           Proxy Statement                            Prospectus of
       for the Special Meeting                 Prosperity Bancshares, Inc.
         of Shareholders of                 In Connection with an Offering of
    Paradigm Bancorporation, Inc.               Shares of its Common Stock

      The boards of directors of Prosperity Bancshares, Inc. and Paradigm
Bancorporation, Inc. have unanimously approved the merger of Paradigm with and
into Prosperity. If the merger is completed, Paradigm shareholders will be
entitled to receive for each share of Paradigm common stock they own up to
1.08658 shares of Prosperity common stock in the following manner: (i) 1.05489
shares of Prosperity common stock which will be issued upon completion of the
merger and (ii) up to an additional 0.03169 shares of Prosperity common stock,
which will be deposited into a holdback escrow on behalf of Paradigm
shareholders for possible future distribution to you based on whether and to the
extent that certain specified loans of Paradigm are repaid or upgraded within
three years after completion of the merger, as further described in this proxy
statement-prospectus.


      Based on the closing price of Prosperity common stock on July 18, 2002 of
$17.69 and a total exchange ratio of 1.08658, the per share value of the
consideration to be received by Paradigm shareholders as of that date would be
$19.22 and the total transaction value would be approximately $45.6 million. Of
this amount, Paradigm shareholders would receive consideration with a value of
$18.66 per share upon completion of the merger and $0.56 per share would be held
in escrow. If the merger were completed as of the date of this proxy
statement-prospectus, a total of 2,505,379 shares of Prosperity common stock
would be issued to Paradigm shareholders upon completion of the merger and
75,270 shares of Prosperity common stock would be deposited into escrow. As a
result, Paradigm shareholders would own approximately 13.4% of the Prosperity
common stock outstanding on a fully diluted basis immediately after the merger.


      The exchange ratio is subject to possible upward adjustment in the event
that the price of a share of Prosperity common stock falls below a pre-agreed
level. Consequently, as a Paradigm shareholder you will not know the exact
number of shares or value of Prosperity common stock you will receive in the
merger at the time you vote on the merger.


      An investment in the Prosperity common stock in connection with the merger
involves risks. See "Risk Factors" beginning on page 28.

      Your board of directors believes that the merger with Prosperity is in the
best interests of Paradigm and you, our shareholders. Accordingly, the board
unanimously recommends that you vote "FOR" the merger.


                           /s/ Charles J. Howard, M.D.

                     Questions and answers about the merger

Q:   What will happen in the merger?


A:   In the merger, Paradigm will be merged with Prosperity, with Prosperity
     being the surviving corporation. As a result of the merger, you will
     receive for each share of Paradigm common stock you own at least 1.05489
     shares of Prosperity common stock. In addition, for each outstanding share
     of your Paradigm common stock, 0.03169 shares of Prosperity common stock
     will be held in escrow on your behalf for possible future delivery to you
     based on whether and to the extent that specified loans made by Paradigm
     prior to the execution of the merger agreement are paid or upgraded within
     three years of completion of the merger. Additionally, upon a decrease in
     the price of Prosperity common stock below a pre-agreed level, Prosperity
     may increase this exchange ratio, which will prevent Paradigm from
     terminating the merger agreement.


Q:   When do you expect the merger to be completed?

A:   We are working to complete the merger during the third calendar quarter of
     2002.

Q:   What are the shareholders being asked to vote upon?

A:   The shareholders are being asked to approve the merger of Paradigm into
     Prosperity.

Q:   What votes are required for approval?


A:   Approval of the merger requires the affirmative vote of holders of a
     majority of the shares of Paradigm common stock outstanding on July 17,
     2002. Our directors and holders of 10% or more of common stock
     (representing approximately 69.7% of the outstanding shares of common
     stock) have agreed to vote all of their shares of Paradigm common stock for
     approval of the merger.

Q:   How does the board of directors recommend that I vote?

A:   Our board of directors, by a unanimous vote, has approved and adopted the
     merger and the merger agreement and recommends that the shareholders vote
     FOR approval of the merger. The board of directors believes that the merger
     is fair to, and in the best interests of, our shareholders.

Q:   What happens if I transfer my shares after the record date?

A:   The record date for the special meeting is earlier than the expected date
     of the merger. Therefore, if you transfer your shares of common stock after
     the record date, but prior to the merger, you will retain the right to vote
     at the special meeting, but the right to receive the merger consideration
     will transfer with the shares of stock.

Q:   What do I need to do now?

A:   After you have thoroughly reviewed this proxy statement-prospectus, simply
     indicate on your proxy card how you want to vote and sign, date and mail it
     in the enclosed envelope as soon as possible.

Q:   What happens if I don't return a proxy card?

A:   The failure to return your proxy card will have the same effect as a vote
     against the merger unless you attend the meeting in person and vote for the
     merger.

Q:   May I vote in person?

A:   Yes.  You may attend the special meeting and may vote your shares in
     person, rather than signing and mailing a proxy card.

                                       1



Q:   May I change my vote after I have submitted my proxy?


A:   Yes.  You may change your vote at any time before your proxy is voted at
     the special meeting by following the instructions as detailed in the
     "Paradigm Special Meeting - Voting Procedures and Revocation of Proxies" on
     page 33. Before your proxy is voted, you may submit a new proxy or you may
     attend the special meeting and vote in person.

Q:   If my shares are held in "street name" by my broker, will my broker vote my
     shares for me?

A:   Your broker will vote your shares only if you provide instructions on how
     to vote. You should instruct your broker how to vote your shares, following
     the directions your broker provides. If you do not provide instructions to
     your broker, your shares will not be voted, which will have the same effect
     as a vote against the merger.

Q:   Do I have any rights to avoid participating in the merger?


A:   Yes. You have the right to withhold your vote for the merger, dissent form
     the merger and seek appraisal value for yours shares as described in
     "Description of the Transaction - Dissenters' Rights of Appraisal and
     Related Issues" beginning on page 55. The appraised value may be more or
     less than the value of the Prosperity common stock being paid in the
     merger.

Q:   Should I send in my stock certificates now?

A:   No.  After the merger is completed, we will send you written instructions
     for exchanging your stock certificates.

Q:   Who can help answer my questions?

A:   If you have additional questions about the merger, you should contact Peter
     E. Fisher at (832) 249-7650.

                                     SUMMARY

         This brief summary highlights selected information from this proxy
statement-prospectus and may not contain all of the information that is
important to you. We urge you to carefully read this entire document and the
other documents we refer to in this document. These documents will give you a
more complete description of the transaction we are proposing. For more
information about Prosperity, see "Where You Can Find More Information" on page
101. We have included page references in this summary to direct you to other
places in this proxy statement-prospectus where you can find a more complete
description of the topics we have summarized. The exchange ratios, number of
shares of Prosperity common stock, per share financial data for Prosperity and
the pro forma financial data have all been adjusted to give effect to
Prosperity's two-for-one stock split in the form of a stock dividend effective
May 31, 2002.

The Companies (pages 86 and 100)

Prosperity Bancshares, Inc.
4295 San Felipe
Houston, Texas 77027
(713) 693-9300

         Prosperity, a Texas corporation, is a financial holding company
registered under the Gramm-Leach-Bliley Act and the Bank Holding Company Act.
Through Prosperity Bank, its wholly owned subsidiary bank, Prosperity conducts a
complete range of commercial and personal banking activities throughout the
greater Houston metropolitan area and nine contiguous counties extending to the
south and southwest. Including the main office of Prosperity in Houston, Texas,
Prosperity operates a total of 32 full-service banking centers. At March 31,
2002, on a consolidated basis, Prosperity had total assets of $1.29 billion,
total deposits of $1.14 billion and shareholders' equity of $92.8 million.

Paradigm Bancorporation, Inc.
3934 FM 1960 West, Suite 330
Houston, Texas 77068
(832) 249-7650

         Paradigm, a Texas corporation, is a financial holding company
registered under the Gramm-Leach-Bliley Act and the Bank Holding Company Act.
Through Paradigm Bank Texas, its wholly owned subsidiary bank, Paradigm conducts
a complete range of commercial and personal banking activities in the greater
Houston metropolitan area and the surrounding communities of Dayton, Winnie, Mt.
Belvieu and Galveston. Including the main office of Paradigm Bank in Houston,
Paradigm operates a total of 11 full-service banking centers. At March 31, 2002,
on a consolidated basis, Paradigm had total assets of $256.7 million, total
deposits of $230.3 million and shareholders' equity of $18.4 million.


The Merger (page 35)


         We have attached the merger agreement to this document as Appendix A.
Please read the merger agreement. It is the legal document that governs the
merger.

         We propose a merger whereby Paradigm will merge with and into
Prosperity and immediately thereafter, Paradigm Bank will merge with and into
Prosperity Bank. In connection with the merger, the existing offices of Paradigm
Bank will become full-service banking centers of Prosperity, except that
Prosperity currently intends to close Paradigm's Medical Center, Dayton Clayton
Road and Silver Ridge banking centers upon completion of the merger or shortly
thereafter. We expect to complete the merger in the third quarter of 2002,
although delays could occur.


What You Will Receive in the Merger (page 35)

         Each of your shares of Paradigm common stock will automatically become
the right to receive up to 1.08658 shares of Prosperity common stock. Of this
amount, you will receive, for each share of your Paradigm common stock, 1.05489
shares of Prosperity common stock upon completion of the merger and an
additional 0.03169 shares of Prosperity common stock will be deposited into the
holdback escrow on your behalf for possible future distribution to you based on
whether and to the extent that specified loans made by Paradigm are repaid or
upgraded within three years after completion of the merger, as further described
in this proxy statement-prospectus.

                                       3



         The exchange ratio is subject to adjustment at Prosperity's discretion
if the price of Prosperity common stock during the 10 consecutive trading days
ending on and including the third trading day immediately prior to completion of
the merger (price measurement period) is less than $12.205 (measurement price)
and the percentage difference between $16.275 and the measurement price is
greater than 10% lower than the percentage decrease between the closing price of
the KBW Bank Index on April 26, 2002 and the average closing price of the KBW
Bank Index during the price measurement period. The adjusted total exchange
ratio will be calculated by dividing the number of shares of Paradigm common
stock outstanding into the number resulting from dividing $31,500,000 by the
measurement price. If Prosperity elects not to adjust the exchange ratio,
Paradigm may terminate the merger agreement. Consequently, you will not know the
exact exchange ratio when you vote on the merger, and even if approved by
Paradigm's shareholders, the merger may not be completed.

         The aggregate number of shares of Prosperity common stock to be
exchanged for each share of Paradigm common stock will be adjusted appropriately
to reflect any change in the number of shares of Prosperity common stock by
reason of any stock dividends or splits, reclassification, recapitalization or
conversion with respect to Prosperity common stock, received or to be received
by holders of Prosperity common stock, when the record date or payment occurs
prior to the closing. Prosperity declared a two-for-one stock split in the form
of a 100% stock dividend effective on May 31, 2002. The exchange ratio and
related amounts in this proxy statement-prospectus have been adjusted to give
effect to the stock split.

         Prosperity will not issue any certificates for fractional shares of
Prosperity common stock in connection with the merger but will instead pay an
amount of cash determined by multiplying the fractional share by the closing
price of Prosperity common stock on the trading day immediately prior to the
closing.

         You will have to surrender your Paradigm common stock certificates in
order to receive new certificates representing shares of common stock of
Prosperity and the cash consideration for your fractional shares. Do not send in
your certificates until you receive written instructions regarding the
certificate exchange process on or after the completion of the merger.


Effect of the Merger on Paradigm Stock Options and Stock Appreciation Rights
(page 36)


         In the merger, each option to purchase shares of Paradigm common stock
pursuant to the Paradigm Bancorporation, Inc. 1999 Stock Incentive Plan that is
outstanding immediately prior to completion of the merger will vest, will be
automatically converted into an option to purchase shares of Prosperity common
stock and will continue to be governed by the terms of the original plan under
which it was issued. The number of shares of Prosperity common stock subject to
each of these converted stock options, as well as the exercise price of these
stock options, will be adjusted to reflect the total exchange ratio in the
merger, and will not be subject to the holdback escrow.

         In addition, each stock appreciation right granted pursuant to the
Paradigm 1998 Stock Appreciation Rights Plan that is outstanding immediately
prior to completion of the merger will be cancelled and automatically converted
into the right of each holder to receive for each outstanding SAR an amount of
cash determined by multiplying the average of the high and low sale prices of a
share of Prosperity common stock on Nasdaq on the second trading day immediately
prior to completion of the merger by the total exchange ratio of 1.08658 or the
adjusted exchange ratio, if applicable, less the exercise price of the SAR under
each holder's SAR agreement. As a result of the merger, all of the options and
SARs will be fully vested.


The Exchange of Paradigm Common Stock for Prosperity Common Stock Will Generally
Be Tax-Free to Shareholders (page 53)


         Prosperity has received an opinion of its legal counsel that generally
for United States federal income tax purposes your exchange of shares of
Paradigm common stock for shares of Prosperity common stock will not cause you
to recognize any gain or loss. However, you will recognize gain or loss in
connection with the receipt of cash in lieu of a fractional share of Prosperity
common stock. The opinion of counsel was filed as an exhibit to the Registration
Statement, of which this proxy statement-prospectus forms a part.

         Our obligation to complete the merger is conditioned on, among other
things, receipt by each of us of an opinion of our respective counsels that the
exchange of shares, except for a gain or loss recognized in connection with the
receipt of the cash consideration and cash instead of a fractional share, will
be tax-free for federal income tax purposes. The conditions relating to the
receipt of the tax opinion may be waived by both of us. Neither of us

                                       4



currently intends to waive the conditions related to the receipt of an updated
tax opinion. However, if these conditions were waived, Paradigm would re-solicit
the approval of its shareholders prior to completing the merger.

         This tax treatment may not apply to every Paradigm shareholder.
Determining the actual tax consequences of the merger to you may be complicated
and will depend on your specific situation and on variables not within our
control. You should consult your own tax advisor for a full understanding of the
merger's tax consequences.

Paradigm's Financial Advisor Has Opined that the Merger is Fair to Shareholders
(page 40)

         Paradigm's financial advisor, Hoefer & Arnett, Incorporated has
delivered a written opinion to the Paradigm board of directors that, as of the
date of this proxy statement-prospectus, the merger consideration is fair to the
holders of Paradigm common stock from a financial point of view. We have
attached this opinion to this document as Appendix C. You should read this
opinion completely to understand the procedures followed, matters considered and
limitations on the reviews undertaken by Hoefer & Arnett in providing its
opinion.

Ownership of Prosperity After the Merger


         Based on the closing price of Prosperity common stock on July 18, 2002
of $17.69 and based on an assumed exchange ratio of 1.08658 (which includes the
shares to be held in escrow), upon completion of the merger, Prosperity would
issue a total of approximately 2,580,649 shares of its common stock to former
Paradigm shareholders, with 75,270 of these shares being placed in the holdback
escrow. Based on these numbers, after the merger on a fully diluted basis (which
includes the issuance of options to acquire shares of Prosperity common stock to
the holders of Paradigm stock options), former Paradigm shareholders would own
approximately 13.4% of the outstanding shares of Prosperity.

         In addition, as of the date of this proxy statement-prospectus, options
to acquire 4,800 shares of Paradigm common stock are exercisable. If these
options are exercised prior to completion of the merger, the shares of Paradigm
common stock issued to these option holders will be converted into shares of
Prosperity common stock in the merger. Assuming a total exchange ratio of
1.08658, if the options to acquire all 4,800 shares are exercised, Prosperity
would be required to issue an additional 5,215 shares of Prosperity common stock
upon completion of the merger.

Comparative Market Prices of Common Stock (page 97)

         Shares of Prosperity common stock are quoted on The Nasdaq Stock Market
under the symbol "PRSP." On May 1, 2002, the last trading day before we
announced the merger, after giving effect to Prosperity's two-for-one stock
split, Prosperity common stock closed at $16.045 per share. On July 18, 2002,
Prosperity common stock closed at $17.69 per share. Shares of Paradigm common
stock are privately held and not listed on an exchange or quoted on an automated
quotation system. The last known sale price of Paradigm common stock of which
management is aware was $9.00 per share on March 20, 2002. You should obtain the
current stock quotation for Prosperity common stock.

Dissenters' Appraisal Rights (page 55)

         As a shareholder of Paradigm, under Texas law you have the right to
dissent from the merger and have the appraised fair value of your shares of
Paradigm common stock paid to you in cash. To dissent and receive the appraised
fair value of your shares, you must:


         .   make a proper demand for appraisal in accordance with the Texas law
             as more fully described on pages 55 to 56 and in Appendix D;


         .   hold your shares of Paradigm common stock until the merger is
             completed;

         .   not vote in favor of the merger (including by appointing a proxy to
             vote your shares); and

         .   otherwise comply with Texas law.

         Persons having beneficial interests in Paradigm common stock held of
record in the name of another person, such as a broker or bank, must act
promptly to cause the record holder to take the actions required under

                                       5



Texas law to exercise your dissenter's rights. The appraised fair value may be
more or less than the value of the shares of Prosperity common stock being paid
in the merger.


Our Reasons for the Merger (pages 38 and 39)


     Our companies are proposing to merge because we believe that by combining
them we can create a stronger and more diversified company that will provide
significant benefits to our shareholders and customers alike. In deciding to
enter into the merger agreement, Paradigm's board of directors considered a
number of factors, including:

     .    the additional capital and resources needed for Paradigm's operations
          to continue to grow and the dilutive effect on shareholders of
          obtaining this additional capital;

     .    the merger consideration in the form of Prosperity common stock, with
          a value as of April 26, 2002 of $16.275 per share, or an aggregate of
          $42.0 million, which represented a 196% premium over the most recent
          sales price of Paradigm common stock of $9.00 per share in March 2002,
          the last day the Paradigm common stock traded prior to Paradigm
          board's approval of the merger agreement;

     .    the current financial services industry environment, including the
          continued consolidation within the industry, the increased competition
          in the market areas served by Paradigm and the costs of evolving
          trends in technology;

     .    the appreciation in the price of Prosperity common stock since
          Prosperity's initial public offering in 1998 and the prospects for
          positive long-term performance of Prosperity common stock; and

     .    the fact that Prosperity common stock is publicly traded on the Nasdaq
          National Market, thereby representing a more liquid investment than
          Paradigm's common stock, which was closely held with little trading
          activity or liquidity.

     In deciding to enter into the merger agreement, Prosperity's board of
directors considered a number of factors, including the opportunity for future
growth and an expanded geographic presence as the acquisition of Paradigm's
locations in the greater Houston area is a natural extension of Prosperity's
existing market areas. In addition, based on management's experience in past
acquisitions, Prosperity anticipates that it will achieve cost savings of
approximately $2.3 million pre-tax over a 12 month period through the
combination of back office operations and the elimination of duplicate general,
administrative and salary and benefits expenses. Prosperity also believes that
the merger may create certain revenue enhancement opportunities as Prosperity
offers new products and services to existing Paradigm customers.


     The discussion of our reasons for the merger includes forward-looking
statements about possible or assumed future results of our operations and the
performance of the combined company after the merger. For a discussion of
factors that could affect these future results, see "A Warning About
Forward-Looking Statements" on page 32.

Special Meeting of Paradigm Shareholders (page 33)

     The special meeting of Paradigm shareholders will be held on August 26,
2002, at 4:00 p.m., local time, at the Gladebrook Banking Center, 3934 FM 1960
West, Suite 330, Houston, Texas. At the Paradigm meeting, you will be asked:


     .    to approve the merger agreement that provides for the merger of
          Paradigm with and into Prosperity; and

     .    to act on any other matters that may be submitted to a vote at the
          special meeting or any adjournment or postponement of the special
          meeting.


Record Date; Majority Shareholder Vote Required (page 33)

     You can vote at the special meeting of Paradigm shareholders if you owned
Paradigm common stock at the close of business on July 17, 2002, the record
date. You can cast one vote for each share of Paradigm common stock that you
owned at that time. Approval of the merger agreement requires the affirmative
vote of the holders of

                                        6



at least a majority of the outstanding shares entitled to vote. Abstentions,
failures to vote and broker non-votes will have the effect of a vote against the
merger agreement and the merger.

     You may vote your shares by attending the meeting or by sending us your
proxy. If you are the record holder of your shares, you can revoke your proxy at
any time before we take a vote at the meeting by sending a written notice
revoking the proxy or a later-dated proxy to the secretary of Paradigm, or by
attending the meeting and voting in person. Attendance at the special meeting
alone will not revoke your proxy. If your shares are held in street name, you
must contact your bank or broker if you wish to revoke your proxy.


Recommendation of Paradigm's Board to Shareholders (page 38)


     The board of directors of Paradigm believes that the merger is fair to you
and in your best interests, and unanimously recommends that you vote FOR the
proposal to approve the merger agreement.


Members of Paradigm's Management are Expected to Vote Their Shares For Approval
of the Merger Agreement (page 33)


     As of July 17, 2002, the record date, the directors and executive officers
of Paradigm, their immediate family members and entities they control were
entitled to vote 1,409,921 shares, or approximately 59.4% of the outstanding
shares of Paradigm common stock and did not beneficially own any shares of
Prosperity common stock.

     Each director and holder of 10% or more of Paradigm common stock who, in
the aggregate, are entitled to vote 69.7% of the outstanding shares of Paradigm
common stock, has executed an agreement pursuant to which he or she has agreed
to vote his or her shares of common stock in favor of approval of the merger
agreement.


Effective Time of the Merger (page 46)


     The merger will become final when articles of merger are filed with the
Secretary of State for the State of Texas. If Paradigm shareholders approve the
merger at the special meeting, and if we obtain all required regulatory
approvals, we anticipate that the merger will be completed in the third quarter
of 2002, although delays could occur.

     We cannot assure you that we can obtain the necessary shareholder and
regulatory approvals or that the other conditions to completion of the merger
can or will be satisfied.


Exchange of Stock Certificates (page 45)

     After the effective time of the merger, you will receive a letter and
instructions from Computershare Investor Services, acting in its role as
Prosperity's transfer agent, regarding the procedure for surrendering your stock
certificates representing shares of Paradigm common stock in exchange for stock
certificates representing shares of Prosperity common stock and cash in lieu of
any fractional share interest. You must carefully review and complete these
materials and return them as instructed along with your stock certificates for
Paradigm common stock. Please do not send Paradigm any stock certificates until
you receive these instructions.


The Distribution of a Portion of the Shares of Prosperity Common Stock to be
Issued in the Merger is Subject to the Terms of a Holdback Escrow Agreement
(page 36)

     Of the shares of common stock that Prosperity will issue in the merger,
Prosperity Bank's Trust Department, as escrow agent, will hold 75,270 shares of
Prosperity common stock in escrow to cover possible losses that may be incurred
by Prosperity in the three year period following completion of the merger with
respect to certain specified loans made by Paradigm prior to execution of the
merger agreement. At the end of the three year period, or sooner if all of these
loans are paid in full or upgraded as described below, the escrow agent shall
distribute to the Paradigm shareholders a number of holdback shares equal to the
aggregate defined value of the holdback shares of $1,225,000 minus the sum of
(1) the dollar amount of any losses related to the specified loans and (2) the
outstanding balance of the specified loans at the end of the three year period,
divided by $16.275 or, if the exchange ratio is adjusted, by $12.205. A
specified loan is considered to be upgraded if deemed by Prosperity in its
discretion to no longer be a specified loan based on the performance of the loan
and the financial stability of the borrower. Each Paradigm shareholder will
receive his or her pro rata share of any distribution of holdback shares, any
dividends paid with respect to such holdback shares and cash in lieu of any
fractional share interests.

                                        7



     If the merger is approved, you will be bound by the terms of the holdback
escrow agreement whether or not you vote in favor of the merger. A form of the
holdback escrow agreement is attached to this proxy statement-prospectus as
Appendix B. Under the terms of the holdback escrow agreement, the shareholder
representative, who may be removed at any time by a majority vote of the former
Paradigm shareholders, will make decisions on behalf of the former Paradigm
shareholders related to the disposition of the shares held in escrow and will
vote the shares in any action requiring a vote of Prosperity shareholders.
Further, the holdback escrow agreement provides that the former Paradigm
shareholders will indemnify the shareholder representative against any liability
incurred in such capacity in good faith other than as a result of willful
misconduct.

     While the shares are held in escrow, the Paradigm shareholders will not
receive any dividends paid against the shares until such time, if any, that the
shares are issued. However, former Paradigm shareholders will be taxed on any
dividends paid during the three year period. See "Material Federal Income Tax
Consequences" on page 53. The rights of Paradigm shareholders under the escrow
agreement are not transferable other than by will or by the laws of descent and
distribution.


Conditions to Completion of the Merger (page 47)

     The completion of the merger depends on a number of conditions being met.
These include, among others:

     .    approval of the merger agreement by the Paradigm shareholders;

     .    approval of the merger by certain federal and state regulatory
          authorities;

     .    receipt by each of us of an opinion of our respective counsel that the
          merger will qualify as a reorganization under Section 368(a) of the
          Internal Revenue Code;

     .    authorization by the Nasdaq Stock Market for the listing of the shares
          of Prosperity common stock to be issued in the merger;

     .    receipt by Prosperity of release agreements signed by the directors
          and certain officers of Paradigm and Paradigm Bank;

     .    receipt by Prosperity of affiliate letters signed by designated
          Paradigm shareholders, directors and officers;

     .    receipt by Paradigm of an opinion of Hoefer & Arnett, Paradigm's
          financial advisor, that the merger is fair to Paradigm shareholders
          from a financial point of view;

     .    execution of an employment and non-compete agreement between Peter E.
          Fisher, President and Chief Executive Officer of Paradigm, and
          Prosperity Bank;

     .    material accuracy of the representations and warranties made by each
          of us as of the date of completion of the merger;

     .    performance or compliance by each of us with all covenants and
          conditions required by the merger agreement; and

     .    absence of a material adverse change in the financial condition,
          results of operation or business of each of us.

     A party to the merger agreement could choose to complete the merger even
though a condition has not been satisfied, as long as the law allows it to do
so. We cannot be certain when or if the conditions to the merger will be
satisfied or waived, or that the merger will be completed.


Regulatory Approvals (page 57)


     We cannot complete the merger unless it is approved by the Board of
Governors of the Federal Reserve System. Once the Federal Reserve approves the
merger, we have to wait anywhere from 15 to 30 days before we can complete the
merger, during which time the Department of Justice can challenge the merger for
antitrust

                                        8



reasons. In addition, completion of the merger is subject to the approval of, or
notice to, state and other regulatory authorities.

     As of the date of this document, we have not received all of the required
approvals. While we do not know of any reason that we would not be able to
obtain the necessary approvals in a timely manner, we cannot be certain when or
if we will obtain them.


Waiver, Amendment and Termination (page 51)


     We may jointly amend the merger agreement and each of us may waive our
right to require the other party to adhere to any term or condition of the
merger agreement. However, we may not amend the merger agreement or waive any
term or condition in the merger agreement after the Paradigm special meeting of
shareholders without approval of the Paradigm shareholders if the amendment or
waiver reduces the consideration that will be received by the Paradigm
shareholders.


     We can mutually agree at any time to jointly terminate the merger agreement
without completing the merger. Also, either of us can decide, without the
consent of the other, to terminate the merger agreement if:

     .    any government agency denies an approval we need to complete the
          merger;

     .    any governmental entity issues a final non-appealable order blocking
          the merger;

     .    the approval of Paradigm shareholders is not obtained by reason of the
          failure to obtain the required vote at the special meeting;

     .    the merger has not been completed by November 27, 2002 or such later
          date approved in writing by our boards of directors, unless the
          failure to complete the merger by that time is due to a breach of the
          merger agreement by the party that seeks to terminate the merger
          agreement;

     .    the other party fails to comply in any material respect with any of
          its covenants or agreements or if any of its representations or
          warranties is innaccurate in any material respect; or

     .    one or more of the conditions to the merger are not met or waived by
          the other party.

     Paradigm may terminate the merger agreement, without the consent of
Prosperity, if:

     .    the average closing price of the Prosperity common stock during the
          price measurement period is less than $12.205 per share, that being
          the measurement price, and the percentage difference between $16.275
          and the measurement price is greater than 10% lower than the
          percentage decrease between the closing price of the KBW Bank Index on
          April 26, 2002 and the average closing price of the KBW Bank Index
          during the price measurement period, and the Prosperity board elects
          not to adjust the merger consideration to an aggregate amount of
          $31,500,000. For these purposes, the price measurement period is the
          10 consecutive trading days ending on and including the third trading
          day immediately prior to the closing; or

     .    the board of directors of Paradigm receives an acquisition proposal
          prior to the effective date of the merger that, based on opinions of
          independent legal counsel and financial advisors, they determine to be
          a superior proposal and that failure to accept such superior proposal
          would be inconsistent with the fiduciary duties of Paradigm's board to
          its shareholders.

     Prosperity may terminate the merger agreement, without the consent of
Paradigm, if:

     .    the board of directors of Paradigm resolves to accept a superior
          proposal, recommends to shareholders of Paradigm that they tender
          their shares in a tender or exchange offer by a third party or
          withdraws or modifies its recommendation in a manner that is adverse
          to Prosperity or approval of the merger or recommends to shareholders
          of Paradigm that they accept or approve an alternative acquisition
          proposal.

                                        9



Expenses and Termination Fees (page 52)

         If we mutually consent to terminate the merger agreement, or if either
of us terminates the merger agreement because the merger has not been completed
by November 27, 2002, then we will each pay our own fees and expenses.

         If the merger agreement is validly terminated by either party, the
merger agreement will become void without any liability on the part of any
person except that Paradigm must pay to Prosperity a termination fee of
$2,500,000 if the merger is terminated in any one of the following
circumstances:

         .    by Paradigm, if the board of directors of Paradigm receives an
              acquisition proposal that, based on opinions of independent legal
              counsel and financial advisors, they determine to be a superior
              proposal and that failure to accept such superior proposal would
              be inconsistent with the fiduciary duties of Paradigm's board to
              its shareholders;

         .    by either Prosperity or Paradigm, if Paradigm's shareholders fail
              to approve the merger agreement, if at the time of such failure,
              Paradigm has received a bona fide acquisition proposal and, within
              nine months of the termination of the merger agreement, Paradigm
              enters into a definitive agreement with any third party with
              respect to any acquisition proposal; or

         .    by Prosperity, if the board of directors of Paradigm resolves to
              accept a superior proposal, recommends to shareholders of Paradigm
              that they tender their shares in a tender or exchange offer by a
              third party or withdraws or modifies its recommendation or
              approval of the merger.

Management and Operations After the Merger (page 57)

         The present management of Prosperity and Prosperity Bank will have the
responsibility of managing Prosperity and Prosperity Bank after the completion
of the merger. The number of directors on Prosperity's board of directors will
be increased by two and Prosperity has agreed to appoint William H. Fagan, M.D.
and Charles J. Howard, M.D. as directors of Prosperity upon completion of the
merger if they are still directors of Paradigm immediately prior to completion
of the merger and are willing and eligible to serve as directors of Prosperity.

         The number of directors for the board of directors of Prosperity Bank
will be increased by two and Prosperity Bank has agreed to appoint Peter E.
Fisher and Leah Huffmeister Henderson as directors of Prosperity Bank upon
completion of the merger if they are still directors of Paradigm Bank
immediately prior to completion of the merger and are willing and eligible to
serve as directors of Prosperity Bank. In addition, Prosperity has agreed to
appoint Mr. Fisher to serve as Vice Chairman of the Board of Prosperity Bank.


Some of the Directors and Officers of Paradigm Have Financial Interests in the
Merger that Differ from Your Interests (page 50)


         Some of the directors and officers of Paradigm have interests in the
merger that differ from, or are in addition to, their interests as shareholders
in Paradigm. These interests include:

         .    certain of Paradigm's executive officers will serve as officers of
              Prosperity Bank following completion of the merger;

         .    Peter E. Fisher, President and Chief Executive Officer of
              Paradigm, will enter into an employment and non-competition
              agreement with Prosperity Bank upon completion of the merger.
              During the two-year term of the agreement, Mr. Fisher will serve
              as Vice Chairman of Prosperity Bank and will receive an annual
              salary equal to $185,000, an annual bonus of not less than
              $15,000 and options to purchase 30,000 shares of Prosperity
              common stock. Upon termination of his employment by Prosperity
              Bank for other than good cause, Mr. Fisher will receive his
              annual salary and bonus for the remaining term of the agreement
              and the 30,000 options will vest. Upon termination of his
              employment for any reason and pursuant to the terms of the
              agreement, Mr. Fisher will receive a non-competition payment of
              $100,000 in consideration for the covenants set forth in the
              agreement, including an agreement not to compete with Prosperity
              Bank for two years following such termination;

                                       10



         .     Peter E. Fisher, Brad Fagan and Jay W. Porter, each an executive
               officer of Paradigm, will receive change in control payments
               aggregating $653,300 pursuant to employment agreements between
               each officer and Paradigm;

         .     eight officers of Paradigm had previously entered into retention
               agreements with Paradigm Bank, which will continue to be
               effective after the merger and which provide 12 months continued
               employment following a change in control or the payment of the
               officer's annual salary for any portion of the 12 month period in
               which the officer is not employed;

         .     certain of Paradigm's executive officers hold options to purchase
               shares of Paradigm common stock and stock appreciation rights
               which will accelerate and become fully vested at the completion
               of the merger. These options will convert into options to acquire
               shares of Prosperity common stock at the total exchange ratio,
               without being subject to the holdback escrow;

         .     Prosperity has agreed to appoint William H. Fagan, M.D. and
               Charles J. Howard, M.D. to serve as directors of Prosperity as of
               completion of the merger;

         .     Prosperity has agreed to appoint Peter E. Fisher and Leah
               Huffmeister Henderson to serve as directors of Prosperity Bank as
               of completion of the merger; and

         .     the right of Paradigm's directors and officers to continued
               indemnification and insurance coverage by Prosperity for acts or
               omissions occurring prior to completion of the merger.

         The members of Paradigm's board of directors knew about these
additional interests and considered them in approving the merger agreement and
the merger.


Your Rights as a Shareholder of Prosperity will be Different than as a
Shareholder of Paradigm (page 59)


         Both Paradigm and Prosperity are Texas corporations and the rights of
their shareholders are governed by Texas law and their respective articles of
incorporation and bylaws. Upon completion of the merger, Paradigm shareholders
will become shareholders of Prosperity and your rights will be governed by
Prosperity's articles of incorporation and bylaws. Prosperity's articles of
incorporation and bylaws will remain the same unless altered, amended or
repealed in the future.

Recent and Pending Prosperity Acquisitions

         On July 15, 2002, Prosperity announced that it had entered into an
agreement to acquire Bank of the Southwest in Dallas, Texas. Bank of the
Southwest has two offices in Dallas, which will continue to operate with the
same management when the acquisition is completed. On June 30, 2002, Bank of the
Southwest reported total assets of $129.6 million, total deposits of $114.3
million, total loans of $55.3 million and total shareholders' equity of $14.7
million. The proposed transaction, which is expected to close in the fourth
quarter of 2002, is subject to approval by Southwest Bank Holding Company
shareholders, approval by regulators and certain closing conditions.

         On July 12, 2002, Prosperity acquired The First State Bank in
Needville, Texas in a cash transaction. The office of The First State Bank was
consolidated with Prosperity Bank's full service banking center in Needville on
July 15, 2002. As of March 31, 2002, The First State Bank reported total assets
of $17.3 million, total deposits of $15.1 million and total loans of $5.3
million.

         On May 8, 2002, Prosperity acquired Texas Guaranty Bank, N.A. for $11.8
million in cash. Texas Guaranty Bank operated three offices in the western
portion of Houston, Texas, all of which became full service banking centers of
Prosperity Bank. As of March 31, 2002, Texas Guaranty Bank reported total assets
of $79.2 million, total loans of $60.8 million and total deposits of $62.3
million.


Recent Developments

Preliminary Financial Results of Prosperity for the Six Months Ended June 30,
2002

         On July 15, 2002, Prosperity announced unaudited preliminary results
for the first six months of 2002. Net income for the six months ended June 30,
2002 was $9.3 million or $0.56 per diluted share compared with $5.2
million or $0.32 per diluted share for the same period in 2001. Included in net
income in 2001 is $2.4 million in

                                       11



one-time merger-related expenses relating to the merger with Commercial
Bancshares, Inc. Additionally, effective January 1, 2002, Prosperity was
required to adopt a new accounting standard which no longer permits goodwill
amortization. Excluding the merger-related expenses and goodwill amortization
expense, net income for the six months ended June 30, 2001 would have been $7.3
million or $0.44 per diluted share. For the six months ended June 30, 2002, the
return on average assets was 1.42% and the return on average shareholders'
equity was 19.77%.

         Net income for the three months ended June 30, 2002 was $4.8 million or
$0.29 per diluted share, an increase in net income of $1.2 million or 34.3%
compared with net income of $3.6 million or $0.22 per diluted share for the same
period in 2001. Adjusting prior period results to exclude the effects of
goodwill amortization, earnings per diluted share would have been $0.24 for the
three months ended June 30, 2001. For the three months ended June 30, 2002, the
return on average assets was 1.43% and the return on average shareholders'
equity was 20.16%.

         At June 30, 2002, Prosperity had total assets of $1.4 billion compared
with total assets of $1.3 billion at March 31, 2002, total deposits of $1.2
billion and total shareholders' equity of $97.4 million. Total loans were $478.9
million at June 30, 2002, which included $42.8 million in loans from
acquisitions closed during the second quarter of 2002.

         Nonperforming assets totaled $444,000 or 0.09% of total loans at June
30, 2002, compared with $1,000 or 0% of total loans at December 31, 2001 and
$439,000 or 0.10% of total loans at June 30, 2001. The provision for credit
losses was $120,000 and $240,000 for the three and six months ended June 30,
2002, respectively. The allowance for credit losses at June 30, 2002 was $6.9
million and represented 1.43% of total loans compared with $5.6 million and
1.30% of total loans at June 30, 2001.



                                                                             As of and for the

          SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA OF PROSPERITY

         The following table summarizes financial results actually achieved by
Prosperity for the periods and at the dates indicated and should be read in
conjunction with Prosperity's consolidated financial statements and the notes to
the consolidated financial statements contained in reports that Prosperity has
previously filed with the Securities and Exchange Commission. Historical
financial information for Prosperity can be found in its Quarterly Report on
Form 10-Q for the three months ended March 31, 2002 and its Annual Report on
Form 10-K for the year ended December 31, 2001. See "Where You Can Find
Additional Information" on 101 for instructions on how to obtain the information
that has been incorporated by reference. Financial amounts as of and for the
three months ended March 31, 2002 and March 31, 2001 are unaudited, but
management of Prosperity believes that such amounts reflect all normal recurring
adjustments necessary for a fair presentation of the results of operations and
financial position for those periods. You should not assume the results of
operations for past periods and for the three months ended March 31, 2002 and
2001 indicate results for any future period.

(3)      Earnings per share amounts for the three months ended March 31, 2001
         and the year ended December 31, 2001 include the merger-related
         expenses of $2.4 million. If these merger-related expenses were
         excluded, basic earnings per share would have been $0.20 and $0.90,
         respectively, and diluted earnings per share would have been $0.20 and
         $0.88, respectively.

(6)      Calculated on a tax-equivalent basis using a 35% federal income tax
         rate for the three month periods ended March 31, 2002 and March 31,
         2001 and the year ended December 31, 2001 and a 34% federal income tax
         rate for the years ended December 31, 1997 through December 31, 2000.

(7)      Calculated by dividing total noninterest expense, excluding securities
         losses and credit loss provisions, by net interest income plus
         noninterest income. The interest expense related to debentures issued
         by Prosperity in connection with the issuance by subsidiary trusts of
         trust preferred securities is treated as interest expense for this
         calculation. Additionally, taxes are not part of this calculation.

         average shareholders' equity to average total assets, which is for
         periods ended at such dates.

(9)      Nonperforming loans consist of nonaccrual loans, loans contractually
         past due 90 days or more and restructured loans.

           SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA OF PARADIGM

         The following table summarizes financial results actually achieved by
Paradigm for the periods and at the dates indicated and should be read in
conjunction with Paradigm's consolidated financial statements and the notes to
the consolidated financial statements. The selected financial data as of
December 31, 2001 and 2000 and for each of the two years in the period ended
December 31, 2001 are derived from Paradigm's audited consolidated financial
statements and related notes included elsewhere in this proxy-statement
prospectus. The selected financial data as of December 31, 1999, 1998 and 1997
and for each of the years in the three year period ended December 31, 1999 is
derived from Paradigm's audited financial statements and related notes, which
are not included in this proxy statement-prospectus. Financial amounts as of and
for the three months ended March 31, 2002 and March 31, 2001 are unaudited, but
management of Paradigm believes that such amounts reflect all normal recurring
adjustments necessary for a fair presentation of the results of operations and
financial position for those periods. You should not assume the results of
operations for past periods and for the three months ended March 31, 2002 and
2001 indicate results for any future period.

---------------------

(1)      For the federal income tax years beginning after December 31, 1997 and
         until December 1, 1999, Paradigm was taxed under Subchapter S of the
         Internal Revenue Code. Consequently, there is no provision for income
         tax in 1998 and the first eleven months of 1999. Based upon Paradigm's
         federal income tax bracket if it were taxed as a C corporation, the
         provision for income tax would have been approximately $548,000 and
         $277,000 for the years ended December 31, 1999 and 1998, respectively,
         which would have resulted in net earnings of $1.3 million and $840,000
         for the years ended December 31, 1999 and 1998, respectively.

(2)      Calculated by dividing total assets, less total liabilities and
         goodwill, by shares outstanding at end of period.

(3)      Calculated on a tax-equivalent basis using a 34% federal income tax
         rate.

(4)      Calculated by dividing total noninterest expenses, excluding securities
         losses and credit loss provisions, by net interest income plus
         noninterest income. For purposes of this calculation, the minority
         interest expense related to the trust preferred securities is treated
         as interest expense. Additionally, income taxes are not part of this
         calculation.

(5)      Asset quality and capital ratios are based on balances at period end,
         except for net loan charge-offs to average loans and average
         stockholders' equity to average total assets, which are based on
         average balances for periods ended at such dates.

(6)      Nonperforming loans consist of nonaccruing loans, loans contractually
         past due 90 days or more and restructured loans.

              UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

     The following unaudited pro forma financial information and related
footnotes as of March 31, 2002 and for the three months ended March 31, 2002 and
the year ended December 31, 2001 are presented to show the impact of the merger
on the historical financial position and results of operations of Prosperity. As
a result of the merger and assuming no adjustment in the exchange ratio,
Paradigm shareholders will receive up to 1.08658 shares of Prosperity common
stock for each share of Paradigm common stock outstanding, with cash paid for
fractional share interests.

     The unaudited Pro Forma Consolidated Balance Sheet reflects the historical
position of Paradigm and Prosperity at March 31, 2002 with pro forma adjustments
based on the assumption that the merger was effective March 31, 2002. The pro
forma adjustments are based on the purchase method of accounting. The unaudited
Pro Forma Consolidated Statements of Income assume that the merger was
consummated on January 1 of the earliest indicated period. The adjustments are
based on information available and certain assumptions that Prosperity believes
are reasonable. Management has not identified, quantified or evaluated any
material restructuring costs at this time. The final allocation of the purchase
price between shareholders' equity and goodwill will be determined after the
merger is completed and after completion of thorough analyses to determine the
fair values of Paradigm's tangible and identifiable intangible assets and
liabilities as of the date the merger is completed. Any change in the fair value
of the net assets of Paradigm will change the amount of the purchase price
allocable to goodwill. Further, changes to Paradigm's stockholders' equity,
including net income from April 1, 2002 through the date the merger is complete,
will also change the amount of goodwill recorded. In addition, the final
adjustments may be different from the unaudited pro forma adjustments presented
herein.

     The unaudited Pro Forma Consolidated Balance Sheet also reflects the
combined historical position at March 31, 2002 of Texas Guaranty Bank, which
Prosperity acquired on May 8, 2002, and The First State Bank, which Prosperity
acquired on July 12, 2002, with pro forma adjustments based on the assumption
that each of the acquisitions was effective March 31, 2002. The unaudited Pro
Forma Consolidated Statements of Income assume that each of these acquisitions
was consummated on January 1 of the earliest indicated period.

     The following information should be read in conjunction with and is
qualified in its entirety by the consolidated financial statements and
accompanying notes of Paradigm included with this proxy statement-prospectus and
the consolidated financial statements of Prosperity incorporated by reference
into this proxy statement-prospectus.

     The unaudited pro forma financial information is intended for informational
purposes and is not necessarily indicative of the future financial position or
future operating results of the combined company or of the financial position or
operating results of the combined company that would have actually occurred had
the merger been in effect as of the date or for the period presented.

Summary of Historical and Pro Forma Per Share Selected Financial Data

         Set forth below are the net earnings, diluted earnings, cash dividends
and book value per common share data for Prosperity and Paradigm on a historical
basis, on a pro forma combined basis and on a pro forma combined basis per
Paradigm equivalent share. Also included are weighted average shares outstanding
and shares outstanding at end of period for Prosperity and Paradigm and on a pro
forma basis. All share and per share data for Prosperity and the pro forma and
pro forma equivalent share information has been adjusted to reflect a
two-for-one stock split in the Prosperity common stock effective May 31, 2002.

         The pro forma data was derived by combining the historical consolidated
financial information of Prosperity and Paradigm using the purchase method of
accounting for business combinations. In July 2001, the Financial Accounting
Standards Board issued Statement No. 142, "Goodwill and Other Intangible
Assets," which eliminates the requirement to amortize goodwill and requires
goodwill to be evaluated annually, or more frequently if impairment indicators
arise, for impairment. However, the historical and pro forma per share financial
information as of and for the year ended December 31, 2001 includes the impact
of amortizing goodwill since Statement No. 142 was not effective for the year
ended December 31, 2001.

         The pro forma per share information gives effect to the completion of
the Texas Guaranty Bank and The First State Bank acquisitions. The Paradigm pro
forma equivalent share information shows the effect of the merger from the
perspective of an owner of Paradigm common stock. The information was computed
by multiplying the pro forma information based on an assumed exchange ratio of
1.08658, which includes 0.03169 shares of Prosperity common stock to be
deposited in the holdback escrow.

         You should read the information below together with the historical
financial statements and related notes and other information of Paradigm
included in this proxy statement-prospectus and the historical financial
statements and related notes that Prosperity has presented in its prior
Securities and Exchange Commission filings. We have incorporated the information
related to Prosperity into this document by reference. See "Where You Can Find
Additional Information" on page 101 for instructions on how to receive copies of
the incorporated information. We expect that Paradigm and Prosperity will incur
merger and integration charges as a result of combining their companies. The pro
forma information, while helpful in illustrating the financial characteristics
of the combined company under one set of assumptions, does not reflect these
expenses or benefits. The unaudited pro forma combined data below is for
illustrative purposes only. The companies may have performed differently had
they always been combined. You should not rely on this information as being
indicative of the historical results that would have been achieved had the

Comparative Stock Prices

         The following table summarizes the market values of Paradigm common
stock and Prosperity common stock on May 1, 2002, the business day prior to the
announcement of the merger, and as of the most recent date practicable preceding
the date of this proxy statement-prospectus. Because the market price of
Prosperity stock is subject to fluctuation, the market value of the shares of
Prosperity common stock that holders of Paradigm common stock would receive upon
consummation of the merger may increase or decrease prior to the receipt of such
shares following completion of the merger. You should obtain current market
quotations for the Prosperity common stock.

                                  RISK FACTORS

         An investment in the Prosperity common stock in connection with the
merger involves certain risks. In addition to the other information contained in
this proxy statement-prospectus, you should carefully consider the following
risk factors in deciding whether to vote for approval of the merger agreement.

                       Risk Factors Related to the Merger

Fluctuations in market price of the shares of Prosperity common stock will
affect the value that Paradigm shareholders receive for their shares of Paradigm
common stock.

         Upon completion of the merger, your shares of Paradigm common stock
will be converted into the right to receive shares of Prosperity common stock.
The number of shares of Prosperity common stock that you will receive in the
merger is fixed, except as discussed below with respect to a decrease in the
market price of Prosperity common stock below a pre-agreed level. As a result of
the uncertainty of the price of Prosperity common stock up to the merger, we
cannot assure you of the market value of the shares of Prosperity common stock
you will receive in the merger.

         The price of Prosperity common stock may vary from its price on the
date of this proxy statement-prospectus and on the date of the special meeting.
Because the date the merger is to be completed will be later than the date of
the special meeting, the price of the Prosperity common stock on the date of the
special meeting may not be indicative of its price on the date the merger is
completed.

         Stock price fluctuations may result from a variety of factors that are
beyond the control of Prosperity, including, among other things, changes in
Prosperity's businesses, operations and prospects, regulatory considerations and
general market and economic conditions. Therefore, Paradigm shareholders cannot
be assured of receiving any specific market value of Prosperity common stock
upon completion of the merger.

If the price of Prosperity common stock falls and the decrease exceeds a
pre-agreed decrease in the KBW Bank Index, and if Prosperity does not elect to
alter the exchange ratio to provide more shares, Paradigm has the right to
terminate the merger agreement.

         The number of shares of Prosperity common stock you will receive in the
merger may increase, but not decrease, from the date of this proxy
statement-prospectus until completion of the merger if the following events
occur and Prosperity in its sole discretion elects to increase the exchange
ratio:

         .    the price of Prosperity common stock during the price measurement
              period is less than $12.205 per share, that being the measurement
              price; and

         .    the percentage difference between $16.275 and the measurement
              price is greater than 10% lower than the percentage decrease
              between the closing price of the KBW Bank Index on April 26, 2002
              and the average closing price of the KBW Bank Index during the
              price measurement period.

         For these purposes, the price measurement period is the 10 consecutive
trading days ending on and including the third trading day immediately prior to
the closing.

         If the Prosperity board of directors does not increase the merger
consideration to a total exchange ratio calculated by dividing the number of
shares of Paradigm common stock outstanding into the number resulting from
dividing $31,500,000 by the measurement price, the Paradigm board of directors
has the power to terminate the merger agreement and abandon the merger, although
there is no obligation of either board to exercise such power.

There are no assurances that Paradigm shareholders will receive any of the
75,270 shares of Prosperity common stock to be held in escrow, yet you will have
to pay taxes with respect to any dividends accrued on these shares.

         Paradigm has agreed to put into escrow, on behalf of Paradigm
shareholders, 75,270 shares of Prosperity common stock to be issued in the
merger. The Trust Department of Prosperity Bank, acting as escrow agent, will
hold these shares to cover possible losses that may be incurred by Prosperity in
the three year period following completion of the merger with respect to
specified loans made by Paradigm prior to the merger. In the event that a
specified loan is either (1) not paid in full or (2) deemed by Prosperity in its
sole discretion to continue to be a

                                       28



specified loan based on the performance of the loan and the financial stability
of the borrower, the shares will be used to compensate Prosperity for the losses
associated with these loans. As a result, you may receive only a portion or none
of the 75,270 shares held in escrow.

         In addition, for the three year period during which your holdback
shares will be held in escrow, you will be required to recognize as income for
federal income tax purposes an amount equal to any dividends that accrue with
respect to your proportionate share of the holdback shares held in escrow in the
tax year in which the dividends are paid into the escrow and interest earned on
such amounts, even though you will not receive these amounts until a later date,
if at all. As a result, dividend payments and interest earned on such amounts
are likely to result in ordinary income, and a related tax liability, for
non-exempt tax paying entities, even though you will only receive the dividends
if and when you receive the related holdback shares. Further, you may not
transfer your interest in these holdback shares other than by will or the laws
of descent and distribution. Therefore, you would be subject to the same tax
liability even if after the merger you sell all of the shares of Prosperity
common stock that you received in the merger.

Prosperity Bank, the escrow agent pursuant to the holdback escrow agreement, is
a wholly-owned subsidiary of Prosperity.

         Pursuant to an agreement between Paradigm and Prosperity, the Trust
Department of Prosperity Bank will act as escrow agent under the terms of the
holdback escrow agreement. While Prosperity Bank's duties and obligations are
set forth in the holdback escrow agreement, as a wholly-owned subsidiary of
Prosperity, Prosperity Bank is not an unaffiliated third party and is controlled
by Prosperity. Pursuant to the terms of the holdback escrow agreement,
Prosperity has sole discretion with respect to determining whether the loans
specified in the holdback escrow agreement have been sufficiently upgraded to
warrant the release of shares of Prosperity common stock held in escrow.

Prosperity may have difficulty combining the operations of Paradigm with its own
operations.

         Because the markets and industries in which Prosperity operates are
highly competitive, and due to the inherent uncertainties associated with the
integration of acquired companies, Prosperity may not be able to integrate the
operations of Paradigm without encountering difficulties including, without
limitation, the loss of key employees and customers, the disruption of their
respective ongoing businesses and possible inconsistencies in standards,
controls, procedures and policies. Additionally, in determining that the merger
is in the best interests of Prosperity and Paradigm, as the case may be, the
board of directors of each of Prosperity and Paradigm considered that enhanced
earnings may result from the completion of the merger, including from reduction
of duplicate costs, improved efficiency and cross-marketing opportunities.
However, there can be no assurance that any enhanced earnings will result from
the merger.

You will have less influence as a shareholder of Prosperity than as a
shareholder of Paradigm.

         As a Paradigm shareholder, you currently have the right to vote in the
election of the board of directors of Paradigm and on other matters affecting
Paradigm. The merger will transfer control of Paradigm to Prosperity and to the
shareholders of Prosperity. When the merger occurs, you will become a
shareholder of Prosperity with a percentage ownership much smaller than your
percentage ownership of Paradigm. Because of this, you will have less influence
on the management and policies of Prosperity than you now have on the management
and policies of Paradigm.

                       Risk Factors Related to Prosperity

Prosperity's profitability depends significantly on local economic conditions.

         Prosperity's success depends primarily on the general economic
conditions of its geographic market. Unlike larger banks that are more
geographically diversified, Prosperity provides banking and financial services
to customers primarily in the greater Houston metropolitan area and the
southeast area of Texas. The local economic conditions in these areas have a
significant impact on Prosperity's commercial, real estate and construction
loans, the ability of the borrowers to repay these loans and the value of the
collateral securing these loans. A significant decline in general economic
conditions, caused by inflation, recession, acts of terrorism, an outbreak of
hostilities or other international or domestic calamities, unemployment or other
factors beyond the control of Prosperity could impact these local economic
conditions and could negatively affect the financial results of its banking
operations.

                                       29



Prosperity may not be able to maintain its historical growth rate, which may
adversely impact its results of operations and financial condition.

      To achieve past levels of growth, Prosperity has initiated internal growth
programs and completed acquisitions of community banks and branches of community
banks. Prosperity may not be able to sustain its historical rate of growth or
may not even be able to grow at all. Prosperity may not be able to obtain the
financing necessary to fund additional growth and may not be able to find
suitable candidates for acquisition. Various factors, such as economic
conditions and competition, may impede or prohibit its opening of new banking
centers. Further, the inability of Prosperity to attract and retain experienced
bankers may adversely affect its internal growth. A significant decrease in
Prosperity's historical rate of growth may adversely impact its results of
operation and financial condition.

Prosperity may be unable to integrate its acquisitions successfully or may be
unable to complete acquisitions.

      Prosperity's growth strategy includes its ability to acquire other
financial institutions. In addition to the proposed merger with Paradigm,
Prosperity acquired Texas Guaranty Bank, N.A., Houston, Texas in May 2002 and
The First State Bank in Needville, Texas in July 2002, and signed a definitive
agreement on July 14, 2002 to acquire Bank of the Southwest in Dallas, Texas. To
the extent that Prosperity grows through acquisitions, Prosperity may not be
able to adequately and profitably manage such growth. Prosperity's ability to
successfully integrate acquired financial institutions and branches of financial
institutions into its operations depends on its ability to:

      .    monitor operations;

      .    control costs;

      .    maintain positive customer relations;

      .    maintain regulatory compliance; and

      .    attract, assimilate and retain qualified personnel.

      If Prosperity fails to successfully integrate an acquired financial
institution's or branch's operations with its operations, Prosperity may
experience interruptions in its business that may have a material adverse impact
on its business, financial condition or results of operations. Successful
integration of these operations could be more expensive than anticipated. In
addition, Prosperity may not be able to complete any future acquisitions.

Prosperity's small to medium-sized business target market may have fewer
financial resources to weather a downturn in the economy.

      Prosperity targets its business development and marketing strategy
primarily to serve the banking and financial services needs of small to
medium-sized businesses. These small to medium-sized businesses generally have
fewer financial resources in terms of capital or borrowing capacity than larger
entities. If general economic conditions negatively impact this major economic
sector in the southeast Texas area or the other markets in which Prosperity
operates, its results of operations and financial condition may be adversely
affected.

Fluctuations in interest rates could reduce Prosperity's profitability.

      Prosperity's earnings are significantly dependent on its net interest
income. Net interest income is the difference between the interest income earned
on loans, investments and other interest-earning assets and the interest expense
paid on deposits, borrowings and other interest-bearing liabilities. Therefore,
any change in general market interest rates, such as a change in the monetary
policy of the Federal Reserve or otherwise, can have a significant effect on
Prosperity's net interest income. Prosperity's assets and liabilities may react
differently to changes in overall market rates or conditions because there may
be mismatches between the repricing or maturity characteristics of the assets
and liabilities. Although Prosperity's asset-liability management strategy is
designed to control its risk from changes in market interest rates, it may not
be able to prevent increases or decreases in interest rates from having a
material adverse effect on Prosperity's net interest margin, results of
operations and financial condition.

                                       30



If Prosperity's allowance for loan losses is not sufficient to cover actual loan
losses, its earnings could decrease.

      Prosperity's loan customers may not repay their loans according to the
terms of these loans and the collateral securing the payment of these loans may
be insufficient to assure repayment. Prosperity may experience significant loan
losses, which could have a material adverse effect on its operating results.
Management makes various assumptions and judgments about the collectibility of
its loan portfolio, including the creditworthiness of the borrowers and the
value of the real estate and other assets serving as collateral for the
repayment of many of its loans. Prosperity maintains an allowance for loan
losses in an attempt to cover any loan losses which may occur. In determining
the size of the allowance, Prosperity relies on its experience and its
evaluation of economic conditions. If Prosperity's assumptions prove to be
incorrect, its current allowance may not be sufficient to cover future loan
losses and adjustments may be necessary to allow for different economic
conditions or adverse developments in its loan portfolio. Material additions to
the allowance could materially decrease net income.

      In addition, federal and state regulators periodically review Prosperity's
allowance for loan losses and may require it to increase its provision for loan
losses or recognize further loan charge-offs, based on judgments different than
those of Prosperity's management. Any increase in Prosperity's loan allowance or
loan charge-offs as required by these regulatory agencies could have a material
negative effect on its operating results.

Prosperity's current concentration in 1-4 family residential loans could provide
lower yields and profitability, and diversification away from this type of loan
may increase its credit risk.

      At March 31, 2002, 1-4 family residential mortgage loans comprised $174.9
million, or 41.6%, of Prosperity's loan portfolio. These loans are secured
primarily by properties located in Prosperity's market area. Because 1-4 family
residential mortgage loans typically have an interest rate that is lower than
other loans, Prosperity's concentration in these loans results in lower yields
and profitability for it. Further, these loans are generally made on the basis
of the borrower's ability to repay and the value of the property securing the
loan. A downturn in the Southeast Texas economy could have an adverse effect on
the ability of borrowers to repay these loans and the value of the property
securing such loans.

      In addition, one of Prosperity's business strategies is to diversify its
loan portfolio. This diversification may result in a gradual increase in its
consolidated credit risk, which means that there would be a greater risk that
borrowers will be unable to repay their loans from Prosperity. Such defaults,
which could result in losses in excess of Prosperity's allowance for credit
losses, may have a material adverse effect on its business, financial condition
or results of operation.

The business of Prosperity is dependent on technology and its inability to
invest in technological improvements may adversely affect its results of
operations and financial condition.

      The financial services industry is undergoing rapid technological changes
with frequent introductions of new technology-driven products and services. In
addition to better serving customers, the effective use of technology increases
efficiency and enables financial institutions to reduce costs. Prosperity's
future success will depend in part upon its ability to address the needs of its
customers by using technology to provide products and services that will satisfy
customer demands for convenience as well as create additional efficiencies in
our operations. Many of Prosperity's competitors have substantially greater
resources to invest in technological improvements. There can be no assurance
that Prosperity will be able to effectively implement new technology-driven
products and services or be successful in marketing these products and services
to its customers.

Prosperity operates in a highly regulated environment and may be adversely
affected by changes in federal and local laws and regulations.

      Prosperity and Prosperity Bank are subject to extensive regulation,
supervision and examination by federal and state banking authorities. Any change
in applicable regulations or federal or state legislation could have a
substantial impact on Prosperity and its subsidiary bank, Prosperity Bank, and
their respective operations. Additional legislation and regulations may be
enacted or adopted in the future that could significantly affect the powers,
authority and operations of Prosperity and Prosperity Bank, which could have a
material adverse effect on Prosperity's results of operations and financial
condition. Further, regulators have extensive discretion and power to prevent or
remedy unsafe or unsound practices or violations of laws by banks and bank
holding companies in the performance of their supervisory and enforcement
duties. The exercise of this regulatory discretion and power may have a negative
impact on Prosperity.

                                       31



      In addition, Prosperity is required to serve as a source of financial
strength to Prosperity Bank, which could result in a decrease of available funds
for dividends to Prosperity's shareholders and cash flow to securities ranking
senior to the Prosperity common stock. Prosperity Bank's operations are also
subject to a wide variety of state and federal consumer protection and similar
statutes and regulations. Such federal and state regulatory restrictions limit
the manner in which Prosperity and Prosperity Bank may conduct business and
obtain financing. Those laws and regulations can and do change significantly
from time to time, and any such change could adversely affect Prosperity's
business, financial condition and results of operations.

                   A WARNING ABOUT FORWARD-LOOKING STATEMENTS

      We have each made forward-looking statements in this proxy
statement-prospectus (and in documents to which we refer you in this document)
that are subject to risks and uncertainties. These forward-looking statements
include information about possible or assumed future results of our operations
or the performance of Prosperity after the merger is completed. When we use any

      .    our revenues after the merger are less than we expected;

      .    deposit attrition, operating costs, customer loss and business
           disruption before and after the merger are greater than we expected;

      .    competition among financial services companies may increase;

      .    we have more difficulty integrating our businesses than we expected;

      .    changes in the interest rate environment reduce our interest margins;

      .    general business and economic conditions in the markets we serve
           change or are less favorable than we expected;

      .    legislative or regulatory changes adversely affect our businesses;

      .    changes occur in business conditions and inflation;

      .    personal or commercial customers' bankruptcies increase;

      .    changes occur in the securities markets; and

      .    technology-related changes are harder to make or more expensive than
           we expected.

                            PARADIGM SPECIAL MEETING

Purpose

      This proxy statement-prospectus is furnished in connection with the
solicitation of proxies by the board of directors of Paradigm from the
shareholders of Paradigm for use at the special meeting. The special meeting is
a meeting of the shareholders of Paradigm at which the shareholders will
consider and vote upon a proposal to approve the merger agreement. A copy of the
merger agreement is attached to this proxy statement-prospectus as Appendix A.

Date, Place and Time of Special Meeting

      The special meeting of Paradigm's shareholders will be held at 4:00 p.m.,
local time, on August 26, 2002 at the Gladebrook Banking Center, 3934 FM 1960
West, Suite 330, Houston, Texas 77068.

Shares Entitled to Vote, Quorum and Vote Required

      The holders of record of the outstanding shares of Paradigm common stock
at the close of business on July 17, 2002 will be entitled to notice of and to
vote at the special meeting and any adjournment or postponement of the special
meeting. At the close of business on that date, there were 2,375,020 shares of
Paradigm common stock issued and outstanding and entitled to vote at the special
meeting.

      At the special meeting, Paradigm shareholders will be entitled to one vote
for each share of Paradigm common stock owned of record on July 17, 2002, the
record date. The holders of a majority of the Paradigm common stock must be
present, either in person or by proxy, to constitute a quorum at the meeting.
Shares of Paradigm common stock present in person or represented by proxy,
including shares whose holders abstain or do not vote and shares held of record
by a broker or nominee that are voted on any matter, will be counted for
purposes of determining whether a quorum exists at the special meeting.

      The affirmative vote of a majority of the issued and outstanding Paradigm
common stock is required to approve the merger agreement. The affirmative vote
of at least a majority of the Paradigm common stock present at the meeting,
either in person or by proxy, is required to approve any other matters that may
be properly presented at the meeting.

      The proposal to approve the merger agreement is a "non-discretionary"
item, meaning that brokers and banks who hold shares in an account for customers
who are the beneficial owners of such shares may not give a proxy to vote those
shares without specific instructions from their customers. Any abstentions and
broker non-votes will have the same effect as votes against approval of the
merger agreement. Accordingly, the Paradigm board of directors encourages you to
complete, date and sign the accompanying proxy card and return it promptly in
the enclosed postage-paid envelope.

      On the record date, the directors and executive officers of Paradigm were
entitled to vote, in the aggregate, 1,409,921 shares of Paradigm common stock,
or approximately 59.4% of the outstanding shares of Paradigm common stock. Each
director and holder of 10% or more of Paradigm common stock who, in the
aggregate are entitled to vote 69.7% of the outstanding shares of Paradigm
common stock, has executed an agreement to vote his or her shares of Paradigm
common stock in favor of approval of the merger agreement. The Paradigm board of
directors unanimously recommends that you vote in favor of approval of the
merger agreement.

      A list of shareholders will be available for examination by holders of the
Paradigm common stock for any purpose related to the special meeting at the
special meeting and during the 10 days prior to the special meeting at
Paradigm's corporate office at 3934 FM 1960 West, Suite 330, Houston, Texas
77068.

Voting Procedures and Revocation of Proxies

      Proxies, in the form enclosed, which are properly executed by the
shareholders and returned to Paradigm and not subsequently revoked, will be
voted in accordance with the instructions indicated on the proxies. Any properly
executed proxy on which voting instructions are not specified will be voted FOR
the proposal to approve the merger agreement. The proxy also grants authority to
the persons designated in the proxy to vote in accordance with their own
judgment if an unscheduled matter is properly brought before the meeting.

                                       33



      If you are the record holder of your shares, you may revoke any proxy
given pursuant to this solicitation by the Paradigm board of directors at any
time before it is voted at the special meeting by:

      .    giving written notice to the Secretary of Paradigm;

      .    executing a proxy bearing a later date filed with the Secretary of
           Paradigm at or before the meeting; or

      .    attending and voting in person at the meeting. Attendance without
           voting at the special meeting will not in and of itself constitute
           revocation of a proxy.

      All written notices of revocation and other communications with respect to
revocation or proxies should be sent to: Paradigm Bancorporation, Inc., 3934 FM
1960 West, Suite 330, Houston, Texas 77068, Attention: William H. Fagan, M.D.,
Secretary. If you hold your shares in street name with a bank or broker, you
must contact the bank or broker if you wish to revoke your proxy.

Other Matters to be Considered

      Paradigm's board of directors is not aware of any business or matter other
than the proposal to approve the merger agreement. If, however, any matter
properly comes before the special meeting, the proxy holders will vote on these
matters in their discretion.

Solicitation of Proxies and Expenses

      This proxy solicitation is made by the Paradigm board of directors.
Paradigm is responsible for its expenses incurred in preparing, assembling,
printing, and mailing this proxy statement-prospectus. Proxies will be solicited
through the mail. Additionally, directors, officers and regular employees of
Paradigm intend to solicit proxies personally or by telephone or other means of
communication. These directors, officers and employees will not be additionally
compensated. Paradigm will reimburse banks, brokers and other custodians,
nominees and fiduciaries for their reasonable expenses in forwarding the proxy
materials to beneficial owners.

                                       34



                         DESCRIPTION OF THE TRANSACTION

      The following information describes material aspects of the merger. It is
not intended to be a complete description of all information relating to the
merger and is qualified in its entirety by reference to more detailed
information contained in the Appendices to this document, including the merger
agreement. A copy of the merger agreement is included as Appendix A and is
incorporated herein by reference. You are urged to read the merger agreement and
other Appendices in their entirety.

Terms of the Merger

      The merger agreement provides for the merger of Paradigm with and into
Prosperity, and immediately thereafter, the merger of Paradigm Bank, a
wholly-owned subsidiary of Paradigm, with and into Prosperity Bank, a
wholly-owned subsidiary of Prosperity. The merger will be effective as soon as
practicable following the receipt of all necessary regulatory and shareholder
approvals and the satisfaction or waiver of all conditions to the consummation
of the merger. As a result of the merger, holders of Paradigm common stock will
be entitled to receive whole shares of Prosperity common stock, with cash paid
in lieu of fractional shares, and will no longer be owners of Paradigm common
stock. As a result of the merger, certificates for Paradigm common stock will
only represent the right to receive the merger consideration pursuant to the
merger agreement, and otherwise will be null and void after completion of the
merger.

      Each share of Paradigm common stock outstanding prior to the effective
time of the merger will be converted into and exchanged for the right to receive
up to 1.08658 shares of Prosperity common stock unless the exchange ratio is
adjusted upward under the conditions described below. Of this amount, for each
share of Paradigm common stock, you will be entitled to receive 1.05489 shares
of Prosperity common stock upon completion of the merger and an additional
0.03169 shares of Prosperity common stock will be deposited in the holdback
escrow for possible future distribution to you based on whether and to the
extent that certain specified loans are paid or upgraded within three years
following completion of the merger. Subject to any adjustment to the exchange
ratio or the issuance of additional shares of Paradigm common stock in
connection with the exercise of stock options after the date of this proxy
statement-prospectus, (1) an aggregate of 2,505,379 shares of Prosperity common
stock, less any shares that would otherwise be distributed to shareholders who
exercise dissenters' rights, will be distributed to shareholders of Paradigm
upon completion of the merger and (2) an aggregate of up to 75,270 shares of
Prosperity common stock, less any shares that would otherwise be distributed to
shareholders who exercise their dissenters' rights, will be distributed in the
holdback escrow for possible future issuance as described below.

      The exchange ratio may be adjusted in Prosperity's discretion if the price
of Prosperity common stock during the 10 consecutive trading days ending on and
including the third trading day immediately prior to closing (price measurement
period) is less than $12.205 (measurement price) and the percentage difference
between $16.275 and the measurement price is greater than 10% lower than the
percentage decrease between the closing price of the KBW Bank Index on April 26,
2002 and the average closing price of the KBW Bank Index during the price
measurement period. The adjusted total exchange ratio would be calculated by
dividing the number of shares of Paradigm common stock outstanding into the
number resulting from dividing $31,500,000 by the measurement price. If
Prosperity elects not to adjust the exchange ratio, Paradigm may terminate the
merger agreement. Consequently, you will not know the exchange ratio when you
vote on the merger, and even if approved by Paradigm's shareholders, the merger
may not be completed.

      In addition, as of the date of this proxy statement-prospectus, options to
acquire 4,800 shares of Paradigm common stock are exercisable. If these options
are exercised prior to completion of the merger, Prosperity must issue
additional shares of Prosperity common stock for each additional share of
Paradigm common stock issued pursuant to the exercise of such options. These
shares, unlike the options, will be subject to the holdback escrow. If all of
the vested options to acquire shares are exercised, based on an assumed total
exchange ratio of 1.08658, Prosperity would be required to issue an additional
5,215 shares of Prosperity common stock upon completion of the merger.

      As noted above, Prosperity will not issue any certificates for fractional
shares of Prosperity common stock in connection with the merger but will instead
pay cash. The amount of cash will be determined by multiplying the fractional
share interest by the closing price of Prosperity common stock on the trading
day immediately prior to the effective time of the merger.

                                       35



Holdback Escrow Agreement

      Of the shares of common stock that Prosperity will issue in the merger,
Prosperity Bank's Trust Department, as escrow agent, will hold 75,270 shares of
Prosperity common stock in escrow to cover possible losses that may be incurred
by Prosperity in the three year period following consummation of the merger with
respect to specified loans made by Paradigm prior to the execution of the merger
agreement. At the end of the three year period, or sooner if all of these loans
are paid in full or upgraded as described below, the escrow agent shall
distribute to the Paradigm shareholders a number of holdback shares equal to the
aggregate defined value of the holdback shares of $1,225,000 minus the sum of
(1) the dollar amount of any losses related to the specified loans and (2) the
outstanding balance of the specified loans at the end of the three year period,
divided by $16.275 or, if the exchange ratio is adjusted, $12.205. A specified
loan is considered to be upgraded if deemed by Prosperity in its discretion to
no longer be a specified loan based on the performance of the loan and the
financial stability of the borrower. Each Paradigm shareholder will receive his
or her pro rata share of any distribution of holdback shares, any dividends paid
with respect to such holdback shares and any cash paid in lieu of any fractional
share interests with respect to the holdback shares.

      If the merger is approved, you will be bound by the terms of the holdback
escrow whether or not you vote in favor of the merger. A form of the holdback
escrow agreement is attached to this proxy statement-prospectus as Appendix B.
Under the terms of the holdback escrow agreement, Walter G. Finger, as the
shareholder representative of the Paradigm shareholders, is required to
participate in and represent the Paradigm shareholders with respect to any
arbitration or legal proceeding relating to the escrow agreement. The
shareholder representative, who may be removed at any time by a majority vote of
those persons who were Paradigm shareholders immediately prior to the merger,
will make decisions on behalf of the former Paradigm shareholders related to the
disposition of the shares held in escrow and other matters and will vote the
shares in any action requiring a vote of Prosperity shareholders. Further, the
holdback escrow agreement provides that the former Paradigm shareholders will
indemnify the shareholder representative against any liability incurred in such
capacity in good faith other than as a result of willful misconduct.

      The Paradigm shareholders will not receive any dividends paid with respect
to the shares held in escrow until such time, if at all, that the shares are
distributed from the escrow. However, former Paradigm shareholders will be
required to pay federal income taxes on any dividends paid into the escrow
during the three year period. See "Material Federal Income Tax Consequences" on
page 53. The rights of Paradigm shareholders under the escrow agreement are not
transferable other than by will or by the laws of descent and distribution.

Effect of the Merger on Paradigm Stock Options and Stock Appreciation Rights

      Pursuant to the merger agreement, any options to purchase shares of
Paradigm common stock pursuant to the Paradigm Bancorporation, Inc. 1999 Stock
Incentive Plan that are outstanding immediately prior to the completion of the
merger shall be automatically converted into an option to purchase shares of
Prosperity common stock and will continue to be governed by the terms of the
original plan under which they were issued. The number of shares of Prosperity
common stock subject to each of these converted stock options, as well as the
exercise price of these stock options, will be adjusted to reflect the total
exchange ratio in the merger and will not be subject to the holdback escrow. In
addition, upon completion of the merger, all unvested options to purchase shares
of Paradigm common stock will immediately vest and become exercisable. As of
July 17, 2002, there were options outstanding to purchase 32,340 shares of
Paradigm common stock at a weighted average exercise price of $11.61 per share.

      Promptly following the merger, Prosperity intends to register with the
Securities and Exchange Commission, the shares of Prosperity common stock
issuable upon the exercise of these converted options. Unless these shares of
Prosperity common stock are acquired by an affiliate of Paradigm, following
registration, the shares issued upon the exercise of the options will be freely
tradeable.

      In addition, each stock appreciation right granted pursuant to the
Paradigm 1998 Stock Appreciation Rights Plan that is outstanding immediately
prior to completion of the merger will be cancelled and automatically converted
into the right of each holder to receive for each SAR an amount of cash
determined by multiplying the average of the high and low sale prices of a share
of Prosperity common stock on Nasdaq on the second trading day immediately prior
to the closing by the total exchange ratio of 1.08658, less the exercise price
of the SAR under each holder's SAR agreement.

                                       36



Background of the Merger

      In the past several years, Paradigm's board of directors and management
have periodically reviewed Paradigm's future prospects for earnings and asset
growth, and the viability of continuing to operate as an independent bank in
accordance with Paradigm's business plan, considering the long-term best
interests of Paradigm and its shareholders. During that time, several interested
parties other than Prosperity contacted Paradigm to explore the possibility of a
merger. Until early 2002, the Paradigm board elected not to pursue these
expressions of interests, believing it to be in the best interests of Paradigm
and its shareholders for Paradigm to remain independent and to focus on building
a strong community bank.

      A significant aspect of Paradigm's growth strategy has included taking
advantage of the consolidation of both large regional banks and community banks
in the greater Houston, Texas metropolitan area by hiring lending officers of
those financial institutions who were able to bring with them significant loan
and deposit portfolios. Additionally, Paradigm developed an aggressive de novo
branching and small bank acquisition strategy. In May 2001, Paradigm opened its
branch in Galveston with the intention of opening one or more branches between
Galveston and Houston. By the end of 2001, Paradigm had 11 banking offices
stretching from the northern portion of Houston, east to Liberty and Chambers
counties and south to Galveston.

      During the fourth quarter of 2001, in connection with its strategic review
of Paradigm's business plan, the board of directors of Paradigm recognized that
for Paradigm Bank to continue to grow at its then current pace, it would need to
raise additional capital, especially if its acquisition strategy were to be
continued. However, the board also recognized the dilutive impact of the raising
of additional capital.

      In July 2001, Mr. Peter Fisher, Paradigm's President and Chief Executive
Officer, and Mr. David Zalman, President and Chief Executive Officer of
Prosperity, had conversations regarding the possible sale of Paradigm to
Prosperity. Based primarily on those discussions, it was apparent to Mr. Fisher
that Prosperity had a similar business model to Paradigm, in that it operated
banking centers in both urban and rural locations. In addition, each institution
utilized the "branch president" concept to maximize responsiveness to customers.

      In October 2001, the Paradigm board met to consider an offer from a
financial institution other than Prosperity. After discussions with Service
Asset Management Company, Dallas, Texas, the board decided to reject the offer
after evaluating it on the basis of consideration proposed, the operations of
the financial institution making the proposal and the expected future operation
of Paradigm. After deliberating on the terms of the proposal, Paradigm's board
determined that the consideration offered was inadequate. Mr. Fisher was
directed to inform the interested institution of its decision.

      Mr. Fisher and Mr. Zalman continued their dialogue with the hope that a
merger could be accomplished. By the middle of February 2002, the possibility of
a merger began to take shape. On April 2, 2002, Mr. Fisher and Mr. Zalman
reached an agreement with respect to the financial aspects of a merger.
Prosperity submitted a letter of intent to Mr. Fisher dated April 3, 2002.
During the week of April 8, Mr. Fisher held several informal meetings with
members of the Paradigm board to inform them of the offer and the terms of the
letter of intent.

      At a special board meeting held on April 15th, the Paradigm board
discussed the reasons for and the benefits of a merger with Prosperity. It
considered the financial performance, stock performance, market position, growth
prospects and other matters concerning Prosperity. The Paradigm board evaluated
Prosperity's offer in relation to the then perceived current market value of
Paradigm common stock and management's estimate of the future value of the
common stock of Paradigm as an independent entity. After this discussion, the
Paradigm board determined that a merger with Prosperity, as proposed, could
provide substantial long-term benefits to Paradigm's shareholders and its other
constituencies, but, before making any decisions, decided to engage a financial
advisor. The board selected Hoefer & Arnett, Incorporated to serve as its
financial advisor in connection with the merger to analyze the transaction and
determine its fairness for Paradigm shareholders. Subject to Hoefer & Arnett's
analysis of the transaction, Mr. Fisher was authorized to execute the letter of
intent and proceed to negotiate the terms of a definitive merger agreement and
related agreements.

      Prosperity's outside counsel delivered to Paradigm and its outside counsel
a draft merger agreement and other related documents on April 22, 2002. During
the course of the next week, Paradigm and Prosperity and their respective
counsel negotiated the terms of the merger documents. Additional special
meetings of the Paradigm board were held on April 25 and April 30, 2002. Both
meetings were attended by representatives of Hoefer & Arnett to discuss the
terms of the deal.

                                       37



      On April 25, 2002, the Paradigm board of directors convened to consider
the merger agreement's proposed escrow of 75,270 shares of Prosperity stock to
cover possible losses on specified loans identified by Prosperity during its due
diligence. Mr. Fisher reviewed the events that had occurred since the last
meeting of the Paradigm board and the reasoning of Prosperity for the proposed
escrow of a specified number of shares. Hoefer & Arnett also made a presentation
to the Paradigm board on the proposed transaction with Prosperity, the current
bank merger and acquisition environment and the results of various financial
analyses Hoefer & Arnett had prepared in connection with the proposed
transaction.

      At the April 30 special board meeting, the board reviewed the terms of the
merger agreement and related agreements that had been negotiated with
Prosperity. There ensued a lengthy discussion concerning the agreement, timing
for execution of the merger agreement and a review of the implications of taking
Prosperity common stock as the merger consideration. Hoefer & Arnett made a
presentation to the Paradigm board on the proposed transaction and the results
of various financial analyses Hoefer & Arnett had prepared in connection with
the proposed transaction. Hoefer & Arnett then delivered its opinion that the
total merger consideration in the form of a minimum of 1.05489 shares of
Prosperity common stock plus an additional 0.03169 shares of Prosperity common
stock deposited into the holdback escrow, subject to adjustment, for each share
of Paradigm common stock was fair to Paradigm shareholders from a financial
point of view. Throughout the presentations, Hoefer & Arnett responded to
numerous questions from the Paradigm board.

      Following a thorough discussion of the terms of the merger agreement, the
structure of the transaction and other items related to the proposed merger, the
Paradigm board determined that the merger pursuant to the definitive agreement
was in the best interests of Paradigm and its shareholders, approved the
proposed merger, subject to the satisfactory finalization of the merger
documents, and authorized Mr. Fisher, as President and Chief Executive Officer
of Paradigm, to execute and deliver the merger documents on behalf of Paradigm.

      Prosperity's board of directors met on April 16, 2002 to discuss and
consider the transaction with Paradigm. Based primarily on an extensive
discussion of the terms of the merger, the financial condition and valuation for
both Paradigm and Prosperity and the expansion of Prosperity's market area as a
result of the proposed merger, Prosperity's board of directors determined that
the transaction with Paradigm was in the best interest of both Prosperity and
its shareholders. As a result, Prosperity's board of directors authorized,
subject to the satisfactory finalization of the merger documents, Mr. David
Zalman, as President and Chief Executive Officer of Prosperity, to execute and
deliver the merger documents on behalf of Prosperity.

      On May 1, 2002, Paradigm and Prosperity entered into the merger agreement
and each financial institution announced the proposed merger. Prosperity issued
a press release announcing the transaction on May 2, 2002.

Recommendation of the Paradigm Board and Paradigm's Reasons for the Merger

      The terms of the merger agreement, including the consideration to be paid
to Paradigm shareholders, were the result of arm's length negotiations between
representatives of Prosperity and Paradigm. In evaluating whether to affiliate
with Prosperity, the Paradigm board considered a number of factors, including,
without limitation, the following:

      .    the additional capital and resources needed for Paradigm's operations
           to continue to grow and the dilutive effect to shareholders of
           obtaining this additional capital;

      .    information regarding the business, operations, earnings, financial
           condition, technological capabilities, management, earnings and
           prospects of each of Paradigm and Prosperity;

      .    the merger consideration in the form of Prosperity common stock with
           a value as of April 26, 2002 of $16.275 per share, or an aggregate of
           $42.0 million, which represented a 196% premium over the most recent
           sales price of Paradigm common stock of $9.00 in March 2002, the last
           day the Paradigm common stock traded preceding Paradigm board's
           approval of the merger agreement;

      .    the current financial services industry environment, including the
           continued consolidation within the industry, the increased
           competition in the market areas served by Paradigm and the costs of
           evolving trends in technology;

                                       38



      .    the appreciation in the price of Prosperity common stock since
           Prosperity's initial public offering in 1998 and the prospects for
           positive long-term performance of Prosperity common stock;

      .    the belief of Paradigm's board that the terms of the merger and the
           merger agreement are fair to and in the best interests of Paradigm
           shareholders;

      .    the analyses provided by Hoefer & Arnett and the oral and written
           opinion of Hoefer & Arnett provided on April 30, 2002 that, as of
           such date, the exchange ratio as set out in the merger agreement, was
           fair from a financial point of view to Paradigm shareholders (see
           "Opinion of Paradigm's Financial Advisor");

      .    the tax-free nature of the exchange of stock as the merger
           consideration to Paradigm shareholders for federal income tax
           purposes;

      .    the fact that Prosperity common stock is publicly traded on the
           Nasdaq National Market, thereby representing a more liquid investment
           than Paradigm common stock, which was closely held with little
           trading activity or liquidity;

      .    Prosperity's record with respect to the employees and customers of
           the banks it acquires, and the effect upon Paradigm's employees and
           the communities that Paradigm serves;

      .    the historical dividends paid by Prosperity on its common stock as
           compared with the dividends paid on Paradigm common stock;

      .    the board's review of other strategic alternatives potentially
           available to Paradigm;

      .    Prosperity's ability to provide the ever-increasing and broadening
           array of financial services and products demanded by Paradigm's
           customers; and

      .    the financial terms of other recent business combinations in the
           banking industry.

      Paradigm's board of directors determined that Paradigm's competitive
position and the value of its stock could best be enhanced through affiliation
with Prosperity. The aggregate price to be paid to holders of Paradigm common
stock resulted from negotiations which considered the historical earnings and
dividends of Prosperity and Paradigm; the potential growth in Paradigm's market
and earnings, both as an independent entity and as a part of a larger
organization such as Prosperity; Paradigm's asset quality; and the effect of the
merger on the shareholders, customers, and employees of Paradigm and the
communities that Paradigm serves.

      The above discussion of the information and factors considered by the
Paradigm board is not intended to be exhaustive, but includes the material
factors the Paradigm board considered. In reaching its determination to approve
and recommend the merger, the Paradigm board did not assign any relative or
specific weights to the foregoing factors, and individual directors may have
given differing weights to different factors.

      The Paradigm board of directors believes that the merger is in the best
interest of Paradigm and its shareholders. Accordingly, the Paradigm board has
unanimously approved the merger agreement and unanimously recommends that you
vote FOR approval of the merger agreement.

Prosperity's Reasons for the Merger

      As a part of Prosperity's growth strategy, Prosperity routinely evaluates
opportunities to acquire financial institutions. The acquisition of Paradigm is
consistent with Prosperity's expansion strategy. Prosperity's board of directors
reviewed the business, financial condition, results of operation and prospects
for Paradigm, the compatibility of Paradigm's market area and management and the
proposed financial terms of the merger. Management of Prosperity believes that
the addition of eight new banking locations will expand Prosperity's geographic
presence in the greater Houston metropolitan area and the surrounding counties
in which Paradigm has locations, provide opportunities for future growth and
also result in the realization of cost savings as a larger organization.
Prosperity's board of directors also considered the addition of experienced
lenders, the financial condition and valuation for both Paradigm and Prosperity,
the tax-free nature of the exchange of Paradigm common stock for shares of
Prosperity common stock as well as the financial and other effects the merger
would have on Prosperity's shareholders.

                                       39



     Further, based on management's experience in past acquisitions, Prosperity
anticipates that it will achieve cost savings of approximately $2.3 million
pre-tax over a 12-month period through the combination of back office operations
and the elimination of duplicate general, administrative and salary and benefits
expenses. Prosperity also believes that the merger may create certain revenue
enhancement opportunities as Prosperity offers new products and services to
existing Paradigm customers.

     In view of the variety of factors considered in connection with its
evaluation of the merger, the Prosperity board did not find it useful to and did
not attempt to quantify, rank or otherwise assign relative weights to the
factors it considered. Further, individual directors may have given differing
weights to different factors. In addition, the Prosperity board did not
undertake to make any specific determination as to whether any particular
factor, or any aspect of any particular factor, was favorable or unfavorable to
its ultimate determination. Rather, the board conducted an overall analysis of
the factors it considered material, including thorough discussions with, and
questioning of, Prosperity's management.

     Opinion of Paradigm's Financial Advisor

     The fairness opinion of Paradigm's financial advisor, Hoefer & Arnett,
Incorporated, is described below. The description contains projections,
estimates and/or other forward-looking statements about the future earnings or
other measures of the future performance of Prosperity and Paradigm. Hoefer &
Arnett has reviewed and consented to the following description relating to its
opinion. You should not rely on any of these statements as having been made or
adopted by Prosperity or Paradigm.

     Paradigm's board of directors retained Hoefer & Arnett as its financial
advisor because Hoefer & Arnett is a nationally recognized investment banking
firm with substantial expertise in transactions similar to the proposed
transaction and is familiar with Paradigm and its business. The firm is a member
of the National Association of Securities Dealers (NASD) with direct access to
inter-dealer markets in NASD Automated Quotation (NASDAQ) and Over-the-Counter
(OTC) securities, and makes markets in securities under its symbol HOFR. As part
of its investment banking activities, Hoefer & Arnett is regularly engaged in
the independent valuation of financial institutions and securities in connection
with mergers, acquisitions, underwritings, sales and distributions of listed and
unlisted securities, private placements and valuations for estate, corporate and
other purposes.

     Hoefer & Arnett is familiar with Paradigm, having provided Paradigm with
certain financial advice from time to time, including having provided financial
advisory services to Paradigm in September 1999 in connection with the
acquisition of Dayton State Bank and in connection with the terms of a common
stock and trust preferred securities offering. In connection with these
services, Paradigm paid Hoefer & Arnett a fee of $48,000. In February 2001,
Hoefer & Arnett acted as Paradigm's co-underwriter in the offering of $6,000,000
trust preferred securities. In connection with this underwriting, Paradigm
allowed Hoefer & Arnett a selling commission of $96,824. In November 1998,
Hoefer & Arnett acted as Prosperity's co-underwriter in the offering of
$20,601,396 of common stock. In connection with this underwriting, Prosperity
allowed Hoefer & Arnett a selling commission of $394,792. Hoefer & Arnett
provides a full range of financial advisory and securities services and, in the
course of its normal trading activities, may effect transactions and hold
securities of Prosperity for its own account and for the accounts of customers.

     At a meeting of Paradigm's board of directors on April 30, 2002, Hoefer &
Arnett rendered to Paradigm's board of directors a verbal opinion that, as of
such date, and subject to various assumptions and matters considered, the terms
of the proposed merger of Paradigm with and into Prosperity were fair to the
holders of Paradigm common stock from a financial point of view. Hoefer & Arnett
has confirmed its April 30, 2002 oral opinion by delivery of its written opinion
to Paradigm's board of directors, dated the date of this proxy
statement-prospectus, that based upon and subject to various assumptions,
matters considered and limitations described therein, the terms of the proposed
merger of Paradigm with and into Prosperity are fair to the holders of Paradigm
common stock from a financial point of view.

     The full text of the Hoefer & Arnett fairness opinion as of the date of
this proxy statement-prospectus describes the procedures followed, assumptions
made, matters considered and limits on the review undertaken, and is attached as
Appendix C to this proxy statement-prospectus. Paradigm's shareholders are urged
to read the Hoefer & Arnett opinion in its entirety.

     No limitations were imposed by Paradigm's board of directors upon Hoefer &
Arnett with respect to the investigations made or procedures followed in
rendering its opinion. Hoefer & Arnett's fairness opinion is based on

                                       40



the financial analyses described below. Hoefer & Arnett's fairness opinion is
for the use and benefit of Paradigm's board of directors in connection with its
consideration of the proposed transaction. Hoefer & Arnett's fairness opinion is
not intended to be and does not constitute a recommendation to any Paradigm
shareholder as to how such shareholder should vote with respect to the proposed
transaction. Hoefer & Arnett's fairness opinion does not address Paradigm's
underlying business decision to proceed with the proposed transaction.

          In arriving at its opinion, Hoefer & Arnett reviewed and analyzed,
among other things, the following information:

          .    the merger agreement;

          .    annual report on Form 10-KSB of Paradigm for the year ended
               December 31, 2001; quarterly reports on Form Y-9C for the
               quarters ended March, 31, 2002, December 31, 2001, September 30,
               2001, June 30, 2001, March 31, 2001 and December 31, 2000; and
               internal financial statements as of June 30, 2002;

          .    annual reports to shareholders and annual reports on Form 10-K of
               Prosperity for the years ended December 31, 2001, December 31,
               2000 and December 31, 1999; quarterly reports on Form 10-Q of
               Prosperity for the quarters ended March 31, 2002, September 30,
               2001, June 30, 2001 and March 31, 2001; and the press release
               announcing June 30, 2002 financial results of Prosperity issued
               on July 15, 2002;

          .    internal financial analyses for Paradigm prepared by Paradigm's
               management;

          .    information obtained from discussions held with senior management
               of Paradigm and Prosperity concerning their past and current
               operations, financial condition and prospects, as well as the
               results of regulatory examinations;

          .    the publicly reported historical prices and trading activity for
               Prosperity common stock;

          .    certain other publicly available financial and other information
               concerning Paradigm and Prosperity;

          .    the nature and financial terms of certain other merger and
               acquisition transactions involving banks and bank holding
               companies; and

          .    such other information, financial studies, analyses and
               investigations that Hoefer & Arnett considered appropriate.

          This discussion of the documents and information reviewed and analyzed
by Hoefer & Arnett is not intended to be exhaustive, but it includes all
material documents, studies, analyses, investigations and information reviewed
and considered by Hoefer & Arnett.

          In conducting its review and in arriving at its opinion, Hoefer &
Arnett relied upon and assumed the accuracy and completeness of the financial
and other information provided to it or publicly available, and did not attempt
to independently verify the same. Hoefer & Arnett relied upon the management of
Paradigm as to the reasonableness of the financial and operating forecasts, and
projections (and the assumptions and bases therefor) provided to it, and Hoefer
& Arnett assumed that such forecasts and projections reflect the best currently
available estimates and judgments of Paradigm management. Hoefer & Arnett relied
on First Call consensus earnings per share estimates for Prosperity for the
years 2002 and 2003. Hoefer & Arnett also assumed, without independent
verification, that the aggregate allowance for credit losses set forth in the
financial statements of Paradigm and Prosperity is adequate to cover such
losses. Hoefer & Arnett did not make or obtain any evaluations or appraisals of
the properties of Paradigm or Prosperity, nor did it examine any individual loan
credit files. For purposes of its opinion, Hoefer & Arnett assumed that the
reorganization would have the tax, accounting and legal effects described in the
merger agreement. Hoefer & Arnett's opinion as expressed herein is limited to
the fairness, from a financial point of view, to the holders of Paradigm common
stock with respect to the terms of the proposed merger of Paradigm with and into
Prosperity.

          As a matter of policy, Paradigm does not publicly disclose internal
management forecasts, projections or estimates of the type furnished to Hoefer &
Arnett in connection with its analysis of the financial terms of the proposed
transaction, and such forecasts and estimates were not prepared with a view
towards public disclosure.

                                       41



These forecasts and estimates were based on numerous variables and assumptions
that are inherently uncertain and that may not be within the control of the
management of Paradigm, including without limitation, the general economic,
regulatory and competitive conditions. Accordingly, actual results could vary
materially from those set forth in such forecasts and estimates.

          As more fully discussed below, Hoefer & Arnett considered such
financial and other factors as Hoefer & Arnett deemed appropriate under the
circumstances, including among others, the following:

          .    the historical and current financial position and results of
               operations of Paradigm and Prosperity, including interest income,
               interest expense, net interest income, net interest margin,
               provision for credit losses, noninterest income, noninterest
               expense, earnings, dividends, internal capital generation, book
               value, intangible assets, return on assets, return on
               shareholders' equity, capitalization, the amount and type of
               nonperforming assets, credit losses and the reserve for credit
               losses, all as set forth in the financial statements for Paradigm
               and Prosperity;

          .    the assets and liabilities of Paradigm and Prosperity, including
               the loan, investment and mortgage portfolios, deposits, other
               liabilities, historical and current liability sources and costs
               and liquidity; and

          .    Hoefer & Arnett's assessment of general economic, market and
               financial conditions and its experience in other transactions, as
               well as its experience in securities valuation and its knowledge
               of the banking industry generally.

          The opinion expressed by Hoefer & Arnett was based upon market,
economic and other relevant considerations as they existed and have been
evaluated as of the date of the opinion and the information made available to it
through that date. Events occurring after the date of issuance of the opinion,
including but not limited to changes affecting the securities markets, the
results of operations or material changes in the assets or liabilities of
Paradigm or Prosperity, could materially affect the assumptions used in
preparing the opinion.

          The following is a summary of the material financial analyses
performed by Hoefer & Arnett in arriving at its opinion and does not purport to
be a complete description of all the analyses performed by Hoefer & Arnett. The
summary includes information presented in tabular format, which should be read
together with the text that accompanies those tables. Hoefer & Arnett believes
that its analyses must be considered as a whole and that selecting portions of
such analyses and the factors considered therein, without considering all
factors and analyses, could create an incomplete view of the analyses and the
processes underlying its opinion. The preparation of a fairness opinion is a
complex process involving subjective judgments and is not necessarily
susceptible to partial analysis or summary description. In its analyses, Hoefer
& Arnett made numerous assumptions with respect to industry performance,
business and economic conditions, and other matters, many of which are beyond
the control of Paradigm and Prosperity. Any estimates contained in Hoefer &
Arnett's analyses are not necessarily indicative of future results or values,
which may be significantly more or less favorable than such estimates. Estimates
of values of companies do not purport to be appraisals or necessarily reflect
the prices at which companies or their securities may actually be sold. Except
as described below, none of the financial analyses performed by Hoefer & Arnett
was assigned a greater significance by Hoefer & Arnett than any other.

          Summary of Proposal. Hoefer & Arnett reviewed the terms of the
proposed merger as described in the merger agreement. Pursuant to the merger
agreement and subject to the terms and conditions therein, each share of
Paradigm common stock outstanding prior to the effective time of the merger will
be converted into and exchanged for the right to receive, for each share of
Paradigm common stock they own, up to 1.08658 shares of Prosperity common stock
unless the exchange ratio is adjusted upward under certain conditions. Of this
amount, Paradigm shareholders will be entitled to receive 1.05489 shares of
Prosperity common stock upon completion of the merger and an additional 0.03169
shares of Prosperity common stock will be deposited in the holdback escrow for
possible future distribution to Paradigm shareholders as provided in the merger
agreement.

          Hoefer & Arnett's analysis is based on 2,375,020 shares of Paradigm
common stock outstanding, the issuance of an aggregate of 2,505,379 shares of
Prosperity common stock and a market price of $17.69 per share for Prosperity
common stock at July 18, 2002, which translates into a total transaction value
of $44,320,154. On a per share basis, each Paradigm shareholder will be entitled
to receive 1.05489 shares of Prosperity common stock at closing, or a
transaction value of an equivalent of $18.66 per share of Paradigm common stock.
Hoefer & Arnett has assumed that none of the 75,270 holdback shares will be
distributed to Paradigm shareholders.

         Analysis of Selected Bank Merger Transactions. Hoefer & Arnett reviewed
information relating to selected banking mergers and acquisitions announced
between January 1, 2001 and July 18, 2002 in which the acquired banking
organizations were located in Texas (the "Selected Transactions"). Hoefer &
Arnett compared financial performance ratios at Paradigm with financial
performance ratios of the banking organizations making up the Selected
Transactions and compared the pricing multiples to be paid for Paradigm with
those paid in the Selected Transactions. This data was obtained from SNL
Financial.

         The following table compares selected performance and financial ratios
of Paradigm at March 31, 2002 with the median ratios for the Selected
Transactions:

                                       Paradigm         Selected Transactions
                                       --------         ---------------------

         Total assets             $256.7 million             $89.4 million
         Return on assets                  0.55%                     1.01%
         Return on equity                  7.76%                    11.81%
         Equity to assets                  7.16%                     8.82%


         On the basis of the pricing multiples for the Selected Transactions,
Hoefer & Arnett calculated a range of purchase prices as a multiple of book
value and earnings. The chart below shows the low, high and median for the
Selected Transactions and the resulting indicated price range for Paradigm based
on Paradigm's equity per share of $7.73 at March 31, 2002, tangible equity per
share of $6.34 at March 31, 2002 and based on 2001 earnings per share of $0.47.

                                  Low     High     Median      Low       High       Median

Price/Book Value                 1.15x    5.13x    1.93x     $  8.89    $  39.65   $  14.92

Price/Tangible Book Value        1.15x    5.13x    1.93x     $  7.29    $  32.52   $  12.24

Price/Earnings                  10.42x   57.56x   18.84x     $  4.90    $  27.05   $   8.85


         Based on the median multiples, this analysis resulted in a range of
imputed values for Paradigm's common stock of between $8.85 and $14.92 per
share, which supports the fairness of the $18.66 per share transaction value.

         Present Value Analysis. Hoefer & Arnett calculated the present value of
theoretical future earnings of Paradigm and compared the transaction value to
the calculated present value of one share of Paradigm's common stock on a
stand-alone basis. Based on projected earnings for Paradigm for 2002 through
2006, discount rates

                                       43



ranging from 10% to 14%, and including a residual value, the stand-alone present
value of Paradigm's common stock ranged from $8.36 to $12.07 per share, which is
below the transaction value of $18.66 per share.

      Discounted Cash Flow Analysis. Using a discounted cash flow analysis,
Hoefer & Arnett estimated the net present value of the future streams of
after-tax cash flow that Paradigm could produce to benefit a potential acquiror,
referred to as dividendable net income, and added a terminal value. Based on
projected earnings for Paradigm for 2002 through 2006, Hoefer & Arnett
calculated assumed after-tax distributions to a potential acquiror such that its
Tier 1 leverage ratio would be maintained at 7.00%. The terminal values for
Paradigm were calculated based on Paradigm's projected 2006 tangible equity and
earnings, the median price to book and price to earnings multiples paid the
Selected Transactions and utilized a discount rate of 12%. This discounted cash
flow analysis indicated implied values of $15.97 per share and $16.37 per share,
which are both below the transaction value of $18.66 per share.

      Accretion/Dilution Analysis. Hoefer & Arnett analyzed the financial
implications of the merger to the Paradigm shareholders. This analysis indicated
the level of accretion to earnings per share, equity per share and dividends per
share that a shareholder of Paradigm would achieve on a pro forma equivalent
basis, based on the closing exchange ratio of 1.05489 and including assumed cost
savings and revenue enhancement opportunities. Such cost savings and revenue
enhancements were assumed to equal 18% of Paradigm's overhead on an annualized
basis, as estimated by Prosperity. The table below summarizes these results:

      Stock Trading History. Hoefer & Arnett reviewed the closing per share
market prices and volumes for Prosperity common stock on a daily basis from
January 2, 2002 to July 18, 2002. Hoefer & Arnett compared the stock price
performance for Prosperity to movements in certain stock indices, including the
Standard & Poor's 500 Index, the Nasdaq Bank Index and the median performance of

     Financial Advisory Fees. In its engagement letter, dated April 16, 2002,
Paradigm agreed to pay Hoefer & Arnett 1.00% of the total consideration, up to a
maximum of $420,000, for its services rendered in connection with the proposed
transaction, including the delivery of its opinion. This fee is contingent on
completion of the transaction.

Exchange of Paradigm Stock Certificates

     As soon as practicable after the effective time of the merger, Prosperity's
transfer and exchange agent, Computershare Investor Services, will mail to each
Paradigm shareholder a form letter of transmittal, together with instructions
for the exchange of such holder's Paradigm stock certificates for a certificate
representing the shares of Prosperity common stock to which he or she is
entitled.

     You should not send in your certificates until you receive a letter of
transmittal and instructions.

     After you surrender to the exchange agent one or more certificates for
Paradigm common stock, together with a properly completed letter of transmittal,
the exchange agent will (1) issue and mail to the holder a certificate
representing the number of whole shares of Prosperity common stock and the cash
payment for fractional shares without any interest thereon to which the holder
is entitled and (2) issue and mail to Prosperity Bank, as escrow agent, the
75,270 shares of Prosperity common stock to be held in escrow pursuant to the
holdback escrow agreement. The exchange agent may issue a certificate for
Prosperity common stock in a name other than the name in which the surrendered
certificate is registered only if (a) the certificate surrendered is properly
endorsed or is otherwise in proper form for transfer and (b) the person
requesting the issuance of the certificate either pays to the exchange agent any
transfer or other taxes required by the issuance of a certificate for shares in
a name other than the registered holder of the certificate surrendered or
establishes to the satisfaction of the exchange agent that the taxes have been
paid or are not due.

     All Prosperity common stock issued in the merger will be deemed issued as
of the effective time of the merger. No dividends with respect to the Prosperity
common stock with a record date after the effective time will be paid to the
former shareholders of Paradigm entitled to receive certificates for shares of
Prosperity common stock until such shareholders surrender their certificates
representing shares of Paradigm common stock. After the certificates are
surrendered, Prosperity will pay the shareholder of record any dividends,
without any interest thereon, which become payable with respect to the shares of
Prosperity common stock represented by the certificate, other than those shares
to be held in escrow. If your certificate for Paradigm common stock is lost,
stolen or destroyed, the exchange agent will issue the shares of Prosperity
common stock upon your submission of an affidavit by you claiming the
certificate to be lost, stolen or destroyed and the posting of a bond in such
amount as Prosperity may direct as indemnity against any claim that may be made
against Prosperity with respect to the certificate.

     Upon completion of the merger, you will cease to have any rights as a
shareholder of Paradigm. Until so surrendered, each certificate will be deemed
for all corporate purposes to represent and evidence solely the right to receive
the consideration to be paid pursuant to the merger agreement. Neither
Prosperity, Paradigm, the exchange agent nor any other party will be liable to
any holder of certificates for any amount paid to a public official pursuant to
any applicable abandoned property, escheat or similar law.

                                       45



Effective Time of the Merger

     Subject to the conditions to complete the merger, the merger will become
effective when articles of merger reflecting the merger become effective with
the Secretary of State for the State of Texas. The merger will be completed on a
date we specify after the conditions to the merger have been satisfied or
waived. Although we anticipate that the merger will become effective during the
third quarter of 2002, delays may occur.

     We cannot assume that the necessary shareholder and regulatory approvals
will be obtained or that the other conditions to the merger can or will be
satisfied. Either of our boards of directors may terminate the merger agreement
if the merger is not completed by November 27, 2002, unless it is not completed
because of the willful breach of the merger agreement by the party seeking
termination.

Conduct of Business Pending Effective Time

     The merger agreement requires Paradigm to maintain the general character of
its business and conduct its business prior to the merger only in the ordinary
course consistent with past practices and prudent banking principles. These
requirements include the following:

     .     Paradigm will use its best efforts to preserve its present business
           organizations, relationships and goodwill with customers, and
           advantageous business relationships and to retain its officers,
           directors and key employees; and

     .     Paradigm will remain current under any loan agreements or other types
           of liability or indebtedness, including any liabilities or
           obligations regarding the junior subordinated debentures in the
           aggregate amount of $6,186,000 and other liabilities relating to the
           amended and restated trust agreement of Paradigm Capital Trust II.

     Without the written consent of Prosperity, Paradigm and its subsidiaries
     may not, among other things:

     .     make or agree to make or renew any loans or other extensions of
           credit in excess of $350,000 to any borrower, with certain
           exceptions;

     .     issue, sell or obligate itself to issue or sell any shares of its
           capital stock or securities convertible into its capital stock,
           except that Paradigm may issue shares of its common stock upon the
           exercise of Paradigm stock options prior to completion of the merger;

     .     grant any stock appreciation rights or other form of incentive
           compensation;

     .     open, close, acquire or sell or agree to acquire or sell any branch
           office or any deposit liabilities;

     .     enter into, amend or terminate any material agreement, contract or
           commitment, except in accordance with prudent banking practices;

     .     acquire or dispose of any material amount of assets or liabilities
           other than in the ordinary course of business consistent with prudent
           banking practices;

     .     grant any severance or termination pay or enter into any employment
           or related agreements for itself or any of its subsidiaries;

     .     pay any dividends other than regular periodic cash dividends paid in
           the ordinary course of business and consistent with past practices;
           however, the parties have agreed that Paradigm may pay a cash
           dividend of $0.05 per share in July 2002 and, if the merger is not
           completed prior to the record date for Prosperity's third quarter
           dividend, Paradigm may pay a cash dividend in an amount equal to the
           quarterly dividend Paradigm shareholders would receive as
           shareholders of Prosperity;

     .     excluding loan commitments made and certificates of deposit issued,
           enter into any contract, agreement or commitment that obligates
           Paradigm or any of its subsidiaries for an amount in excess of
           $10,000 over the term of any such contract, agreement or commitment;

     .     amend or change any provision of its articles of incorporation or
           bylaws;

                                       46



     .     sell, transfer, convey or otherwise dispose of any real property,
           including other real estate owned;

     .     foreclose upon or otherwise acquire any commercial real property
           prior to the receipt and approval of Prosperity of a Phase I
           environmental review of such property;

     .     increase or decrease the rate of interest paid on deposit accounts
           other than in accordance with Paradigm's past practices;

     .     establish a new subsidiary;

     .     voluntarily make any material change in the interest rate risk
           profile of Paradigm Bank;

     .     materially deviate from policies and procedures existing as of the
           date of the merger agreement with respect to classification of
           assets, allowance for loan losses or accrual of interest on assets
           except as otherwise required by the merger agreement;

     .     excluding deposits, certificates of deposit, FHLB advances and
           borrowings consistent with past practices, undertake any additional
           borrowings in excess of ninety (90) days;

     .     modify any outstanding loan or acquire any loan participation unless
           such modification is made in the ordinary course of business,
           consistent with past practices; or

     .     make any capital expenditures individually in excess of $25,000 or in
           the aggregate in excess of $100,000, other than previously disclosed
           binding commitments or expenditures necessary to maintain existing
           assets in good repair.

     Refer to the merger agreement for additional restrictions on the conduct of
the business of Paradigm pending the merger.

Financial Interests of Paradigm Directors and Officers in the Merger

     As a Paradigm shareholder, in considering the recommendations of the
Paradigm board of directors to vote for the proposal to approve the merger
agreement, you should be aware that certain directors and officers of Paradigm
may have interests in the merger that are in addition to or different from the
interests of Paradigm shareholders. The Paradigm board of directors was aware of
these interests and considered them in approving the merger agreement.

     Continued Employment. Certain of Paradigm's executive officers will serve
as officers of Prosperity Bank following completion of the merger.

     Employment and Non-competition Agreement. Upon completion of the merger,
Prosperity Bank will enter into an employment and non-competition agreement with
Peter E. Fisher, Paradigm's President and Chief Executive Officer. During the
two-year term of the agreement, Mr. Fisher will serve as Vice Chairman of
Prosperity Bank and receive:

     .    an annual salary of $185,000;
     .    an annual bonus of not less than $15,000; and
     .    upon completion of the merger, Prosperity will deliver to Mr. Fisher
          an incentive stock option agreement granting him an option to purchase
          30,000 shares of Prosperity common stock.

If Prosperity Bank terminates Mr. Fisher's employment without good cause, as
defined in the agreement, Mr. Fisher will be entitled to receive his annual
salary and bonus for the remaining term of the agreement and any of the 30,000
options which are unvested will vest and become immediately exercisable.

     In consideration for the covenants agreed to by Mr. Fisher, he will receive
a lump sum payment of $100,000 upon termination of his employment with
Prosperity Bank as provided for in the agreement. For two years following such
termination, Mr. Fisher is prohibited from:

     .    competing with Prosperity Bank within Houston, Texas and a 50 mile
          radius of Houston;
     .    soliciting employment or employing employees of Prosperity Bank; and
     .    soliciting customers or prospective customers of Prosperity Bank to
          cease or reduce their business relationships with Prosperity Bank.

     In addition, under the agreement, Mr. Fisher is prohibited from disclosing
or improperly using any confidential information, former employee information or
third party information.

     Retention Agreements. Eight officers of Paradigm had previously entered
into retention agreements with Paradigm Bank which provide for 12 months
continued employment following a change in control or the payment of 12 months
salary prorated for any of the 12 month period the officer was employed
following the change in control. These agreements will continue to be effective
after the merger.

     Change in Control Payments. Paradigm has employment agreements with Peter
E. Fisher, Brad Fagan and Jay W. Porter that provide for payments upon a change
in control. The merger will result in payment prior to completion of the merger
of approximately $362,500, $170,800 and $120,000 to Messrs. Fisher, Fagan and
Porter, respectively.

     Stock Options. Certain of Paradigm's officers hold options to purchase
32,340 shares of Paradigm common stock at an average exercise price of $11.61,
27,540 of which are unvested with an average exercise price of $11.48. Upon
completion of the merger all unvested options will vest and become immediately
exercisable. In addition, all options to acquire Paradigm common stock will
convert into options to acquire shares of Prosperity common stock at the total
exchange ratio, without being subject to the holdback escrow. As a result,
option holders, including certain officers, could exercise their options
immediately after completion of the merger and receive shares of Prosperity
common stock without being subject to the holdback escrow.

     Stock Appreciation Rights. Certain of Paradigm's officers hold stock
appreciation rights which will accelerate and become fully vested upon
completion of the merger. Each SAR will be cancelled and automatically converted
into a specified cash payment.

                                       50



     Director Positions. Prosperity has agreed to appoint William H. Fagan, M.D.
and Charles J. Howard, M.D. to serve as directors of Prosperity upon completion
of the merger, and Prosperity has agreed to appoint Peter E. Fisher and Leah
Huffmeister Henderson to serve as directors of Prosperity Bank upon completion
of the merger.

     Indemnification. Prosperity has agreed, for a period of three years after
completion of the merger, to indemnify and hold harmless any person who has
rights to indemnification from Paradigm and its subsidiaries to the fullest
extent permitted by Texas law and Paradigm's articles and bylaws.

     Insurance. Prosperity agreed that for a period of three years after
completion of the merger it will maintain directors' liability insurance
covering the persons presently covered by directors' liability insurance
policies of Paradigm.

Employee Matters

     All employees of Paradigm who continue employment after the closing shall
be eligible to participate in the employee benefit plans and programs of
Prosperity and Prosperity Bank. Prosperity will credit such employees for their
length of service with Paradigm for all purposes under each of the employee
benefit plans and programs, except stock option plans.

Amendment and Termination

     Mutual Consent. The merger agreement may be terminated and the merger
abandoned at any time upon the mutual consent of Prosperity and Paradigm.

     By Either Party. The merger agreement may be terminated and the merger
abandoned at any time prior to the effective date of the merger by either
Prosperity or Paradigm if:

     .    any court of competent jurisdiction or other federal or state
          governmental body shall have issued an order, decree or ruling or
          taken any other action restraining, enjoining or otherwise prohibiting
          the merger and such order, decree, ruling or other action shall have
          been final and non-appealable;

     .    any of the transactions contemplated by the merger agreement are
          disapproved by any regulatory authority or other person whose approval
          is required to consummate any of such transactions;

     .    the approval of the merger agreement by Paradigm shareholders is not
          obtained by reason of the failure to obtain the required vote at the
          special meeting;

     .    the merger has not have become effective by November 27, 2002 and the
          party exercising its termination right is not in default under the
          merger agreement; or

     .    any of the conditions to the respective obligations of Prosperity,
          Prosperity Bank or Paradigm have not been met or waived by the other
          party.

     By Paradigm. The merger agreement may be terminated and the merger
abandoned at any time prior to the effective date of the merger by Paradigm if:

     .    Prosperity fails to comply in any material respect with any of its
          covenants or agreements or if any of its representations or warranties
          shall be inaccurate in any material respect;

     .    any of the conditions to the obligations of Paradigm to complete the
          merger have not been met or waived by Paradigm;


     .    the average closing price of Prosperity common stock during the price
          measurement period is less than $12.205 per share, that being the
          measurement price, and the percentage difference between $16.275 and
          the measurement price is greater than 10% lower than the percentage
          decrease between the closing price of the KBW Bank Index on April 26,
          2002 and the average closing price of the KBW Bank Index during the
          price measurement period; provided, however, that Prosperity has the
          right to nullify Paradigm's termination right by adjusting the
          exchange ratio. For these purposes, the price measurement period is
          the 10 consecutive trading days ending on and including the third
          trading day immediately prior to the closing; or

                                       51



     .    Paradigm receives an acquisition proposal prior to the effective date
          that Paradigm's board of directors determines in its good faith
          judgment and in the exercise of its fiduciary duties, based in part on
          the written opinion of its independent legal counsel and the written
          opinion of an investment banking firm of national reputation, that
          such alternative acquisition proposal would be more favorable to
          Paradigm's shareholders than the merger, and that refusing the
          alternative proposal would be inconsistent with the fiduciary duties
          of Paradigm's board to its shareholders.

     In the event Paradigm desires to terminate the merger agreement as provided
in the third item above, Paradigm must notify Prosperity in writing of its
intent to terminate within two business days following the end of the 10 day
trading period over which the average trading price is determined. Prosperity
has five days from the receipt of the notice to cure the grounds for
termination.

     By Prosperity. The merger agreement may be terminated and the merger
abandoned at any time by Prosperity if:

     .    Paradigm fails to comply in any material respect with any of its
          covenants or agreements or if any of its representations or warranties
          shall be innaccurate in any material respect;

     .    any of the conditions to the obligations of Prosperity to complete the
          merger have not been met or waived by Prosperity;


     .    the board of directors of Prosperity determines, after consultation
          with counsel, that it will be unable to obtain any required regulatory
          approval or such approval contains conditions that would materially
          and adversely affect the financial consequences of the merger; or

     .    the board of directors of Paradigm

               .    received an acquisition proposal which the board of
                    directors resolves to accept;

               .    recommended to Paradigm's shareholders that they tender
                    their shares of Paradigm common stock in a tender or
                    exchange offer to a third party;

               .    withdrew or modified, in any manner that is adverse to
                    Prosperity, its recommendation or approval of the merger; or

               .    recommended to Paradigm shareholders that they accept or
                    approve an alternative acquisition proposal.

Expenses

     Except as otherwise noted above, Prosperity and Paradigm will each pay
their own expenses in connection with the merger.

Termination Fee

     The provisions of the merger agreement relating to expenses and termination
fees as well as the confidentiality provisions will continue in effect
notwithstanding termination of the merger agreement. If the merger agreement is
validly terminated by either party, the merger agreement will become void
without any liability on the part of any person except that Paradigm must pay to
Prosperity a termination fee of $2,500,000 if the merger is terminated as set
forth below:

     .    by Paradigm, if it receives an acquisition proposal that Paradigm's
          board of directors determines in its good faith judgment and in the
          exercise of its fiduciary duties, based in part on the written opinion
          of its independent legal counsel and the written opinion of an
          investment banking firm of national reputation, that such alternative
          acquisition proposal would be more favorable to Paradigm's
          shareholders than the merger, and that refusing the alternative
          proposal would be inconsistent with the fiduciary duties of Paradigm's
          board to its shareholders;

     .    by either Prosperity or Paradigm, if certain mutual conditions have
          not been met at closing due to the failure of Paradigm's shareholders
          to approve the merger agreement, if at the time of such failure

                                       52



          Paradigm has received a bona fide acquisition proposal and, within
          nine months of the termination of the merger agreement, Paradigm
          enters into a definitive agreement with any third party with respect
          to any acquisition proposal; or

     .    by Prosperity, if the board of directors of Paradigm

               .    received a superior acquisition proposal which the board of
                    directors resolves to accept;

               .    recommended to Paradigm's shareholders that they tender
                    their shares of Paradigm common stock in a tender or
                    exchange offer to a third party;

               .    withdrew or modified, in any manner that is adverse to
                    Prosperity, its recommendation or approval of the merger; or

               .    recommended to Paradigm shareholders that they accept or
                    approve an alternative acquisition proposal.

Nasdaq Stock Market Listing

     Prosperity has agreed to use its best efforts to cause the shares of
Prosperity common stock to be issued in the merger to be approved for quotation
on the Nasdaq National Market. The obligations of the parties to complete the
merger are subject to approval for quotation of such shares on the Nasdaq
National Market.

Material Federal Income Tax Consequences

     The following discussion is a general summary of the anticipated material
United States federal income tax consequences of the merger to Paradigm
shareholders who hold Paradigm common stock as a capital asset. This discussion
is based upon the Internal Revenue Code, regulations promulgated by the United
States Treasury Department, court cases and administrative rulings in each case
as in effect as of the date hereof and all of which are subject to change at any
time, possibly with retroactive effect.

     The obligations of the parties to complete the merger are conditioned upon
the receipt by Prosperity and Paradigm of an opinion of counsel from Bracewell &
Patterson, L.L.P. as to the anticipated United States federal income tax
consequences of the merger, but specifically excluding the following:

     .    state, local, foreign or other federal tax consequences of the merger
          not specifically addressed in the opinion;

     .    federal income tax consequences to Paradigm shareholders who are
          subject to special rules under the Internal Revenue Code, such as
          foreign persons, tax-exempt organizations, insurance companies,
          financial institutions, dealers in securities and other persons who do
          not own such stock as a capital asset;

     .    federal income tax consequences affecting shares of Paradigm common
          stock acquired upon the exercise of stock options, similar derivative
          securities or otherwise as compensation; and

     .    the federal income tax consequences to holders of options or other
          rights to acquire shares of Paradigm common stock and Prosperity
          common stock or persons who hold their Paradigm common stock as part
          of a straddle, hedge or conversion transaction.

     Bracewell & Patterson, L.L.P., counsel to Prosperity has delivered its tax
opinion to Prosperity, subject to the limitations discussed above, on the basis
of facts, representations and assumptions set forth or referred to in such
opinion which are consistent with the state of facts existing at the effective
time of the merger. In rendering its tax opinion, such counsel may require and
rely upon representations and covenants, including those contained in
certificates of officers of Prosperity and Paradigm, reasonably satisfactory in
form and substance to such counsel. An opinion of counsel represents counsel's
best legal judgment, but has no binding effect or official status of any kind,
and no assurance can be given that contrary positions will not be taken by the
IRS or a court considering the issues. We have not requested nor do we intend to
request a ruling from the IRS as to the tax consequences of the merger.

                                       53



     Bracewell & Patterson, L.L.P. has rendered its opinion that for United
     States federal income tax purposes:

     .    the merger will constitute a reorganization within the meaning of
          Sections 368(a) of the Internal Revenue Code and Prosperity and
          Paradigm will each be a party to the reorganization;

     .    except as discussed below, you will not recognize any gain or loss for
          United States federal income tax purposes when you exchange your
          Paradigm common stock solely for Prosperity common stock pursuant to
          the merger;

     .    the aggregate tax basis in the shares of Prosperity common stock you
          received as a result of the merger, including the holdback shares held
          pursuant to the holdback escrow agreement, will be equal to the
          aggregate tax basis of the shares of Paradigm common stock you
          surrender in the exchange, increased by the amount of gain recognized
          and reduced by the tax basis of any Paradigm common stock for which
          you receive cash in lieu of a fractional share interest;

     .    the holding period of the Prosperity common stock that you receive in
          the merger, including the holdback shares held pursuant to the
          holdback escrow agreement, will include the holding period of the
          shares of Paradigm common stock that you exchange; and

     .    neither Paradigm nor Prosperity will recognize any gain or loss for
          United States federal income tax purposes as a result of the merger.

     A copy of this opinion is attached as Exhibit 8.1 to the registration
statement of which this proxy statement-prospectus forms a part. It is a
condition to completion of the merger that each of us receive an updated opinion
of Bracewell & Patterson, L.L.P. The conditions relating to receipt of the tax
opinion may be waived by both of us. Neither of us currently intends to waive
the conditions related to the receipt of an updated tax opinion. However, if
these conditions are waived, Paradigm will circulate additional materials to
their shareholders and re-solicit approval of the merger.

     Fractional shares of Prosperity common stock will not be issued in the
merger. You will recognize gain or loss for United States federal income tax
purposes with respect to the cash you receive instead of a fractional share
interest in Prosperity common stock. Your gain or loss will equal the difference
between the amount of cash you receive and the tax basis of your Paradigm common
stock surrendered in the merger that is allocated to fractional shares. This
gain or loss will be capital gain or loss, and will be a long-term capital gain
or loss if your stock has been held for more than one year at the time the
merger is completed.

     You will be treated as owning the shares of Prosperity common stock held
under the holdback escrow agreement. If dividends are paid with respect to the
holdback shares, you will be required to report the dividends as ordinary income
even though you do not receive the cash payment. In addition, you will be
required to report as ordinary income any interest earned on the escrowed
dividends. If some or all of the holdback shares are returned to Prosperity to
discharge a liability under the holdback escrow agreement, you will be treated
as though you sold your portion of the returned shares and will recognize
capital gain or loss based on the difference between your basis in the returned
shares and the value of the shares at the time they are released. You will
increase your basis in any remaining shares by the amount of the liability that
was satisfied. If you no longer own any Prosperity common stock at the time the
escrow is terminated and none of the holdback shares are distributed to you, you
will likely report a capital loss equal to the amount of gain recognized. You
may also be able to report as an ordinary loss the amount of any dividends and
interest held by the escrow and not distributed to you to the extent you have
previously reported ordinary income attributable to such dividends and interest.
You should consult your own tax adviser regarding the proper tax treatment of
the escrowed shares.

     If you exercise the right to dissent in connection with the merger and
receive only cash in exchange for your Paradigm common stock, you will be
treated as having received such cash as a distribution in redemption of your
Paradigm common stock and will generally recognize a capital gain or loss equal
to the difference between the amount of cash received and the adjusted basis of
your Paradigm common stock. However, different tax consequences could apply to
such payment, under your particular facts and circumstances, including whether
you are deemed under any applicable attribution rules to own Prosperity common
stock if the payment is deemed to have the effect of a dividend distribution and
not a redemption treated as an exchange under the principles of Section 302 of
the Code.

                                       54



     The foregoing is a summary discussion of material federal income tax
consequences of the merger. The discussion is included for general information
purposes only and may not apply to a particular Paradigm shareholder in light of
such shareholder's particular circumstances. Paradigm shareholders should
consult their own tax advisors as to the particular tax consequences to them of
the merger, including the application of state, local and foreign tax laws and
possible future changes in federal income tax laws and the interpretation
thereof, which can have retroactive effects.

Dissenters' Rights of Appraisal and Related Issues

     Paradigm shareholders have a statutory right to dissent from the merger by
following the specific procedures set forth below. If the merger is approved by
the shareholders and consummated, any Paradigm shareholder who properly perfects
his or her dissenters' rights will be entitled to receive an amount of cash
equal to the fair value of his or her shares of Paradigm stock rather than being
required to receive the consideration established by the merger agreement. The
following summary is not a complete statement of the statutory dissenters'
rights of appraisal, and such summary is qualified by reference to the
applicable provisions of the Texas Business Corporation Act, or the TBCA, which
are reproduced in full in Appendix D to this proxy statement-prospectus. You
must follow the exact procedure required by the TBCA in order to properly
exercise your dissenters' rights of appraisal and avoid waiver of those rights.

     Any Paradigm shareholder who desires to dissent from the merger must file a
written objection to the merger with the Secretary of Paradigm, William H.
Fagan, M.D., 3934 FM 1960 West, Suite 330, Houston, Texas 77068, prior to the
meeting. The written notice must state that the shareholder will exercise his or
her right to dissent if the merger is consummated and give the shareholder's
address to which notice of effectiveness of the merger should be sent. A vote
against the merger is not sufficient to perfect a shareholder's statutory right
to dissent from the merger. If the merger is consummated, each shareholder of
Paradigm who sent notice to Paradigm as described above and who did not vote in
favor of the merger will be deemed to have dissented from the merger. Failure to
vote against the merger will not constitute a waiver of the dissenters' rights
of appraisal; on the other hand, a vote in favor of the merger will constitute
such a waiver.

     As the company surviving the merger, Prosperity will be liable for any
payments to dissenting shareholders and, within 10 days of the effective date of
the merger, must notify the dissenting shareholders in writing that the merger
has occurred. Each dissenting shareholder so notified must, within 10 days of
the delivery or mailing of such notice, make a written demand on Prosperity, for
payment of the fair value of the dissenting shareholder's shares as estimated by
the dissenting shareholder. Failure to follow this procedure will constitute a
waiver of his dissenter's rights of appraisal by such dissenting shareholder.
The demand shall state the number and class of the shares owned by the
dissenting shareholder and the fair value of the shares as estimated by the
dissenting shareholder. The fair value of the shares shall be the value thereof
as of the date immediately preceding the meeting, excluding any appreciation or
depreciation in anticipation of the merger. Dissenting shareholders who fail to
make a written demand within the 10 day period will be bound by the merger and
lose their rights to dissent. Within twenty days after making a demand, the
dissenting shareholder must submit his stock certificates to Prosperity for
notation thereon that such demand has been made. Failure to do so shall
terminate the dissenting shareholder's right to dissent, unless a court
determines otherwise. Dissenting shareholders who have made a demand for payment
of their shares shall not thereafter be entitled to vote or exercise any other
rights of a shareholder except the right to receive payment for their shares
pursuant to the provisions of the TBCA and the right to maintain an appropriate
action to obtain relief on the basis of fraud.

     Within twenty days after receipt of a dissenting shareholder's demand
letter as described above, Prosperity shall deliver or mail to the dissenting
shareholder written notice stating that Prosperity accepts the amount claimed in
the demand letter and agrees to pay that amount within ninety days after the
effective date and upon surrender of the certificates duly endorsed by the
dissenting shareholder or containing Prosperity's written estimate of the fair
value of the shares of Paradigm stock together with an offer to pay such amount
within ninety days after the effective date of the merger if Prosperity receives
notice, within sixty days after the effective date of the merger, stating that
the dissenting shareholder agrees to accept that amount and upon surrender of
the certificates duly endorsed by the dissenting shareholder. In either case,
the dissenting shareholder shall cease to have any ownership interest in
Paradigm following consummation of the merger.

     If the dissenting shareholder and Prosperity cannot agree on the fair value
of the shares within sixty days after the effective date, either the dissenting
shareholder or Prosperity may, within sixty days of the expiration of the
initial sixty day period, file a petition in any court of competent jurisdiction
in Harris County, Texas requesting a

                                       55



finding and determination of the fair value of the dissenting shareholder's
shares. Each dissenting shareholder is not required to file a separate petition.
If one dissenting shareholder files a petition, Prosperity must, within 10 days
after being served with a copy of the petition, file, with the clerk of the
court in which the petition was filed, a list containing the names and addresses
of the dissenting shareholders with whom agreements as to the value of their
shares have not been reached. If Prosperity files the petition, it will include
the list as part of the filing. The court will give notice of the time and place
of the hearing on the petition to the dissenting shareholders named on the list.
Dissenting shareholders so notified by the court will be bound by the final
judgment of the court regarding fair value of the shares. If no petition is
filed within the appropriate time period, then all dissenting shareholders who
have not reached an agreement with Prosperity on the value of their shares shall
be bound by the merger and lose their rights to dissent.

     After a hearing concerning the petition, the court shall determine which
dissenting shareholders have complied with the provisions of the TBCA and have
become entitled to the valuation of, and payment for, their shares, and shall
appoint one or more qualified appraisers to determine the value of the shares of
Paradigm stock in question. The appraiser or appraisers shall afford a
reasonable opportunity to the parties to submit pertinent evidence as to the
value of the shares. The appraiser or appraisers shall determine such value and
file a report with the court, notice of which will be given to the parties in
interest. The court shall then in its judgment determine the fair value of the
shares of Paradigm. The judgment of the court shall be binding on Prosperity and
on all dissenting shareholders receiving notice of the hearing. This value may
be more than, less than, or equal to what is received by non-dissenting
shareholders. The court shall direct Prosperity to pay such amount, together
with interest thereon beginning ninety-one days after the effective date to the
date of judgment, to the dissenting shareholders entitled thereto. The judgment
shall be payable upon the surrender to Prosperity of the certificates fully
endorsed by the dissenting shareholder. Upon payment of the judgment, the
dissenting shareholder shall cease to have any interest in the certificates. All
court costs shall be allotted between the dissenting shareholders and Prosperity
in the manner the court determines to be fair and equitable.

     Any dissenting shareholder who has made a written demand on Prosperity for
payment of the fair value of his or her Paradigm stock may withdraw such demand
at any time before payment for his shares has been made or before a Petition has
been filed with an appropriate court for determination of the fair value of such
shares. If a dissenting shareholder withdraws his or her demand, or if he or she
is otherwise unsuccessful in asserting his or her dissenters' rights of
appraisal, such dissenting shareholder shall be bound by the merger and his or
her status as a former shareholder shall be restored without prejudice to any
corporate proceedings, dividends, or distributions that may have occurred during
the interim.

     In the absence of fraud in the transaction, a dissenting shareholder's
statutory right to appraisal is the exclusive remedy for the recovery of the
value of his shares or money damages to the shareholder with respect to the
merger. See Appendix D.

Accounting Treatment

     Under generally accepted accounting principles, the merger will be
accounted for under the purchase method of accounting. The assets and
liabilities of Paradigm, including identifiable intangible assets, will be
reflected in the consolidated financial statements of Prosperity based upon the
estimated fair values as of the effective time of the merger. Results of
operations will be reflected in the consolidated financial statements of
Prosperity for all periods subsequent to the effective time of the merger. The
excess purchase price over the fair market value of assets is recorded as
goodwill and is not amortized. Instead, goodwill is evaluated annually, or more
frequently if impairment indicators arise, for impairment.

Restrictions on Resales of Prosperity Common Stock

     Prosperity common stock to be issued in the merger will be registered under
the Securities Act of 1933. Therefore, the Prosperity common stock to be issued
to Paradigm shareholders in the merger will be freely transferable by Paradigm
shareholders who are not considered to be "affiliates" of either of us.
"Affiliates" generally are defined as persons or entities who control, are
controlled by or are under common control with either of us at the time of the
Paradigm special meeting and generally include executive officers, directors and
beneficial owners of 10% or more of the Paradigm common stock.

     If you are considered an affiliate of Paradigm or become an affiliate of
Prosperity after the merger, you may resell the shares of Prosperity common
stock acquired in connection with the merger only pursuant to an

                                       56



effective registration statement under the securities laws, pursuant to Rule 145
of the Securities and Exchange Commission's rules, or in transactions otherwise
exempt from registration under the securities laws. Under Rule 145, during the
first calendar year after the merger becomes effective, affiliates of Paradigm
may publicly resell the Prosperity common stock they receive in the merger but
only within certain limitations as to the number of shares of Prosperity common
stock they can sell in any three-month period and as to the manner of sale.
After the one-year period, affiliates of Paradigm who are not affiliates of
Prosperity may resell their shares without restriction. Prosperity must continue
to satisfy its reporting requirements under the Securities Exchange Act of 1934
in order for these affiliates of Paradigm to resell, under Rule 145, shares of
Prosperity common stock received in the merger. Prosperity is not obligated and
does not intend to register for resale the shares issued to affiliates of
Paradigm.

     A condition to Prosperity's obligation to complete the merger is that each
affiliate of Paradigm signs a written agreement to the effect that he or she
will not offer or sell or otherwise dispose of any of the shares of Prosperity
common stock issued to him or her in the merger in violation of the Securities
Act of 1933.

Regulatory Approvals

     The merger must be approved by the Board of Governors of the Federal
Reserve System. On June 21, 2002, Prosperity filed an application with the
Federal Reserve Bank of Dallas to obtain prior approval of the merger. It is
expected that the Federal Reserve will approve the application in July 2002. The
merger of Paradigm Bank into Prosperity Bank must be approved by the Federal
Deposit Insurance Corporation (FDIC) and the Texas Department of Banking. On
June 3, 2002, Prosperity filed an application with the FDIC and Banking
Department to obtain approval of the bank merger. It is expected that the FDIC
and Banking Department will approve the application in August 2002.

     A period of 15 to 30 days must expire following approval by the Federal
Reserve during which time the Department of Justice may file objections to the
merger under the federal antitrust laws. While Paradigm and Prosperity believe
that the likelihood of such action is remote, there can be no assurance that the
Department of Justice will not initiate such a proceeding, or if such a
proceeding is initiated, as to the result of any such challenge.

     The approval of any application merely implies satisfaction of regulatory
criteria for approval, which does not include review of the merger from the
standpoint of the adequacy of the consideration to be received by, or fairness
to, shareholders. Regulatory approvals do not constitute an endorsement or
recommendation of the proposed merger.

     Prosperity and Paradigm are not aware of any governmental approvals or
compliance with banking laws and regulations that are required for the merger to
become effective other than those described above. There can be no assurance
that any required approval or action can be obtained or taken prior to the
special meeting of Paradigm. The receipt of all necessary regulatory approvals
is a condition to completing the merger.

                   MANAGEMENT AND OPERATIONS AFTER THE MERGER

     Upon completion of the merger, the number of directors of Prosperity will
be increased by two and Prosperity has agreed to appoint William H. Fagan, M.D.
and Charles J. Howard, M.D. as directors of Prosperity if they are still
directors of Paradigm immediately prior to completion of the merger and are
willing and eligible to serve as directors of Prosperity.

                           OF PROSPERITY AND PARADIGM

         The rights of Paradigm shareholders under the articles of incorporation
and bylaws of Paradigm will differ in some respects from the rights Paradigm
shareholders will have as shareholders of Prosperity under the articles of
incorporation and bylaws of Prosperity. Copies of Prosperity's articles of
incorporation and bylaws have been previously filed by Prosperity with the
Securities and Exchange Commission. Copies of Paradigm's articles of
incorporation and bylaws are available upon written request from Paradigm.

         Certain differences between the provisions contained in the Texas
Business Corporation Act, Paradigm's articles of incorporation and bylaws, and
Prosperity's articles of incorporation and bylaws as such differences may affect
the rights of shareholders are summarized below. The summary set forth below is
not intended to be complete and is qualified by reference to Texas law, the
Paradigm articles of incorporation, the Paradigm bylaws, the Prosperity articles
of incorporation and the Prosperity bylaws.

            Summary of Material Differences Between Current Rights of
                 Paradigm Shareholders and Rights Those Persons
          Will Have as Shareholders of Prosperity Following the Merger



                                          Paradigm                                       Prosperity

                        of Paradigm.  Following the completion of      Prosperity.
                        the merger, rights of Paradigm shareholders
                        who become Prosperity shareholders will be
                        governed by Texas law and the articles of
                        incorporation and bylaws of Prosperity.

Authorized Capital      Paradigm's authorized capital stock consists   Prosperity's authorized capital stock
Stock:                  of 25,000,000 shares of common stock, par      consists of 50,000,000 shares of common
                        value $1.00 per share, and 10,000,000 shares   stock, par value $1.00 per share, and
                        of preferred stock, par value $10.00 per       20,000,000 shares of preferred stock, par
                        share.                                         value $1.00 per share.

                        three-year term.  This means that only         three-year term.
                        one-third of the board is elected at each
                        annual meeting of shareholders.  The
                        classification makes it more difficult to
                        change the composition of Paradigm's Board
                        of Directors because at least two annual
                        meetings of shareholders are required to
                        change control of the Board of Directors.

                     not the benefit resulted from an action

                     Paradigm's articles of incorporation
                     provide that no director of Paradigm will
                     be liable to Paradigm or its shareholders
                     for monetary damages for an act or
                     omission in the director's capacity as a
                     director, except to the extent the
                     foregoing exemption from liability is not
                     permitted under Texas law. Paradigm's
                     articles of incorporation and bylaws
                     provide the corporation shall have the
                     power to purchase and maintain insurance
                     on behalf of directors against any
                     liability incurred by directors in such a
                     capacity or arising out of such person's
                     status.

Indemnification:     Under Texas law, Paradigm may indemnify an        Prosperity's articles of incorporation
                     individual acting in his capacity as an           and bylaws provide for mandatory
                     officer or director against liability             indemnification to the fullest extent
                     incurred if (1) he conducted himself in           allowed by Texas law for all former or
                     good faith; and (2) he believed: (a) in           present directors or officers and all
                     the case of conduct in his official               persons who were serving at the request
                     capacity with Paradigm, that his conduct          of Prosperity as a director, officer,
                     was in Paradigm's best interest and (b)           partner or trustee of another entity.
                     in all other cases, that his conduct was
                     at least not opposed to its best
                     interests; and (3) in the case of a
                     criminal proceeding, he had no
                     reasonable cause to believe his conduct
                     was unlawful. Texas law also provides
                     that a director may not be indemnified
                     with respect to a proceeding (1) in
                     which the person is found liable on the
                     basis that personal benefit was
                     improperly received by him, whether or
                     not the benefit resulted from an action
                     taken in the person's official capacity
                     or (2) in which the person is found
                     liable to the corporation. Paradigm's
                     articles of incorporation and bylaws
                     provide for mandatory indemnification to
                     the fullest extent allowed by Texas law
                     for all former or present directors or
                     officers and all


                                       62




                                                                    
                     persons who were serving at the request of
                     Paradigm as a director, officer, partner or
                     trustee of another entity.


     In addition, Prosperity is subject to the provisions of the Texas Business
Combination Law (Articles 13.01 through 13.08 of the TBCA), which provide that a
Texas corporation that has 100 or more shareholders or any class or series of
its voting shares registered under the Securities Exchange Act of 1934 or
similar successor statute, or qualified for trading in a national market system
may not engage in certain business combinations, including mergers,
consolidations and asset sales, with a person, or an affiliate or associate of
such person, who is an "affiliated shareholder" (generally defined as the holder
of 20% or more of the corporation's voting shares) for a period of three years
from the date such person became an affiliated shareholder unless: (1) the
business combination or purchase or acquisition of shares made by the affiliated
shareholder was approved by the board of directors of the corporation before the
affiliated shareholder became an affiliated shareholder or (2) the business
combination was approved by the affirmative vote of the holders of at least
two-thirds of the outstanding voting shares of the corporation not beneficially
owned by the affiliated shareholder, at a meeting of shareholders called for
that purpose (and not by written consent), not less than six months after the
affiliated shareholder became an affiliated shareholder. As long as Paradigm has
less than 100 shareholders or is not a public company as described above,
Paradigm is not subject to this law.

     The Texas Business Combination Law is not applicable to:

     .    the business combination of a corporation:

               .    where the corporation's original charter or bylaws contain a
                    provision expressly electing not to be governed by the Texas
                    Business Combination Law;

               .    that adopts an amendment to its charter or bylaws before
                    December 31, 1997, expressly electing not to be governed by
                    the Texas Business Combination Law; or

               .    that adopts an amendment to its charter or bylaws after
                    December 31, 1997, by the affirmative vote of the holders,
                    other than affiliated shareholders, of at least two-thirds
                    of the outstanding voting shares of the corporation,
                    expressly electing not to be governed by the Texas Business
                    Combination Law;

     .    a business combination of a corporation with an affiliated shareholder
          that became an affiliated shareholder inadvertently, if the affiliated
          shareholder:

               .    as soon as practicable divests itself of enough shares to no
                    longer be an affiliated shareholder; and

               .    would not at any time within the three year period preceding
                    the announcement of the business combination have been an
                    affiliated shareholder but for the inadvertent acquisition;

     .    a business combination with an affiliated shareholder that was the
          beneficial owner of 20% or more of the outstanding voting shares of
          the corporation on December 31, 1996, and continuously until the
          announcement date of the business combination;

     .    a business combination with an affiliated shareholder who became an
          affiliated shareholder through a transfer of shares of the corporation
          by will or intestate succession and continuously was such an
          affiliated shareholder until the announcement date of the business
          combination; and

     .    a business combination of a corporation with a wholly owned subsidiary
          if the subsidiary is not an affiliate or associate of the affiliated
          shareholder other than by reason of the affiliated shareholder's
          beneficial ownership of the voting shares of the corporation.

Neither the articles of incorporation nor the bylaws of Prosperity contain any
provision expressly providing that Prosperity will not be subject to the Texas
Business Combination Law. The Texas Business Combination Law may have the effect
of inhibiting a non-negotiated merger or other business combination involving
Prosperity, even if such event would be beneficial to Prosperity's shareholders.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
            FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF PARADIGM

         Management's Discussion and Analysis of Financial Condition and Results
of Operation of Paradigm analyzes the major elements of Paradigm's balance
sheets and statements of income. This section should be read in conjunction with
Paradigm's consolidated financial statements and the accompanying notes
contained elsewhere in this proxy statement-prospectus.

Overview

         During the quarter ended March 31, 2002, Paradigm earned $354,000, or
$0.15 per share (basic and diluted), compared with $471,000, or $0.20 per share
(basic and diluted), for the same period in 2001. Paradigm earned a return on
average assets of 0.55% and 0.87% and a return on average equity of 7.76% and
10.78% for the first quarters of 2002 and 2001, respectively. Paradigm paid no
dividends during the quarters ended March 31, 2002 and 2001.

         Paradigm's total assets were $256.7 million at March 31, 2002 compared
with $259.3 million at December 31, 2001, a decrease of $2.6 million, or 1.0%.
Total loans decreased $200,000 to $170.6 million at March 31, 2002 compared with
total loans of $170.8 million at December 31, 2001. Total deposits were $230.3
million at March 31, 2002, a decrease of $2.1 million, or 0.9%, compared with
$232.4 million at December 31, 2001.

         In December 2000, Paradigm changed the name of its subsidiary bank,
Woodcreek Bank, to Paradigm Bank Texas to reflect its expanded customer base and
broader geographic range. Also in December 2000, Paradigm merged Dayton State
Bank, which was acquired in December 1999 and operated as a separate bank
subsidiary, into Paradigm Bank in order to expand and improve services offered
to its banking customers, develop efficiencies from a unified management and
consolidate the management, loan processing, back office and accounting
operations.

         During the first quarter of 2001, Paradigm, through its subsidiary
Paradigm Capital Trust II, issued $6.0 million in trust preferred securities.
The proceeds were used mainly to redeem all of Paradigm's outstanding 10.375%
debentures and for general corporate purposes. For more information, see the
discussion in "Financial Condition - Trust Preferred Securities" on page 81.

         From August 2000 through May 2001, Paradigm opened three new banking
centers. The three new locations are in the Copperfield and Gladebrook areas of
north and northwest Houston and in downtown Galveston. Due to the proximity of
Paradigm's Copperfield and Gladebrook banking centers to the Cy-Fair banking
center, Paradigm closed its Cy-Fair banking center on December 1, 2001. Paradigm
moved the staff and most of the business from Cy-Fair to the nearby Gladebrook
location, enabling it to realize cost savings without material loss of loans or
deposits, and without material charges to income.

         During 2001, the Federal Reserve decreased the discount rates eleven
times, totaling 475 basis points. Due to rate re-pricing differences among
Paradigm's interest-bearing assets and liabilities, these rate reductions
effectively lowered Paradigm's net interest margin by 85 basis points for 2001
versus 2000.

         Changing Paradigm Bank's name, merging Dayton State Bank into Paradigm
Bank, staffing and establishing new locations, establishing a consolidated
operations center and modernizing computer systems all represented significant
long-term investments, which increased costs in 2001. Due to these factors and
those discussed below, Paradigm earned $1.1 million, or $0.47 per share (basic
and diluted), in 2001, versus $2.2 million, or $0.94 per share (basic and
diluted), in 2000. Paradigm posted returns on average assets of 0.48%, 1.05%,
and 1.49% for 2001, 2000 and 1999, respectively. For those same years, Paradigm
earned returns on average equity of 6.37%, 13.73%, and 21.11%, respectively.
Dividends paid per weighted average share outstanding (basic and diluted) for
2001, 2000 and 1999, respectively, were $0.06, $0.30 and $0.48.

         Despite the downward pressure on earnings, Paradigm achieved
significant asset and deposit growth in 2001. Total assets grew to $259.3
million at December 31, 2001 from $215.3 million at December 31, 2000, an
increase of $44.0 million, or 20.4%. Total loans increased to $170.8 million at
December 31, 2001 from $133.5 million at December 31, 2000, an increase of $37.3
million, or 27.9%. Total deposits grew $44.4 million, or 23.6%, in 2001, to
$232.4 million at December 31, 2001. Assets, loans and deposits grew in 2001 due
to the growth in branches opened in 2000 and 2001 and the development of
additional business at existing branches.

Results of Operations

Net Interest Income

         Net interest income, a main source of Paradigm's earnings, is the
amount by which interest income exceeds interest expense. Interest rate
fluctuations and changes in the amount and type of earning assets and
liabilities combine to affect net interest margins and net interest income.
Changes in yields earned on interest-earning assets, such as loans and
investments, and rates paid on interest-bearing deposits and other borrowed
funds are called rate changes. Changes in the amount and mix of interest-earning
assets and interest-bearing liabilities are referred to as volume changes.

         For the quarter ended March 31, 2002, net interest income before
provision for credit losses increased $37,000 to $2.6 million compared with the
same period in 2001, as the increase in average loans offset an 89 basis point
decrease in net interest margin resulting from the interest rate declines
throughout 2001.

         Net interest income before provision for credit losses decreased
$377,000 or 3.5%, to $10.3 million for the year ended December 31, 2001 compared
with $10.7 million in 2000. After discount rate reductions by the Federal
Reserve Board, which totaled 475 basis points in 2001, interest rates earned on
Paradigm's interest-earning assets decreased more rapidly and more significantly
than the rates paid on its interest-bearing liabilities. The average rate earned
on interest-earning assets was 7.78% in 2001, down 101 basis points from 8.79%
in 2000. The average rate paid for interest-bearing liabilities decreased 27
basis points to 4.04% in 2001 versus 4.31% in 2000. Paradigm's net interest
margin of 5.15% in 2001 was 85 basis points lower than in 2000.

         The increase in average assets and liabilities, and related interest
income and expense, from 1999 to 2000 was mainly due to the purchase of Dayton
State Bank in December 1999.

                                       65



     The following tables present for the periods indicated the total dollar
amount of interest income from average interest-earning assets and the resultant
yields, as well as the interest expense on average interest-bearing liabilities,
expressed both in dollars and rates. No tax-equivalent adjustments were made to
the average balances or interest amounts, and all average balances are daily
average balances. Non-accruing loans have been included in the tables as loans
carrying a zero yield.

     ___________________

     (1)  Yield on securities is based on amortized cost and does not include
          unrealized gains or losses. Average balances for time deposits with
          other banks are included in average securities balances above, in the
          amounts of $2,902, $3,512, and $7,619 for the years ended December 31,
          2001, 2000 and 1999, respectively.

     (2)  Net interest margin equals net interest income divided by average
          interest-earning assets.

     (3)  To make pretax income and yields on tax exempt investments and loans
          comparable to those for taxable investments and loans, a
          tax-equivalent adjustment was computed using the federal income tax
          rate of 34%. The average balances of non-taxable securities which are
          included in the average securities balances above were $11,072,
          $11,088 and $9,763 for the years ended December 31, 2001, 2000 and
          1999, respectively.

                                       67



         In 2001, average interest-earning assets increased $22.4 million, or
12.5%, over 2000, mainly due to an increase in average loan volume of $23.4
million, or 19.1%. The increase in loans was not enough, however, to offset the
effect of the 101 basis point decrease in average yield in 2001, resulting in
lower total interest income.

         Growth in savings, money market and time deposits helped boost average
interest-bearing liabilities by $15.6 million, or 13.3%, in 2001 compared with
2000. The benefit from the gradual reduction of 27 basis points on average rates
paid on interest-bearing liabilities was offset by the deposit growth, resulting
in higher total interest expense for 2001.

         The following tables present the dollar amount of changes in interest
income and interest expense for the major components of interest-earning assets
and interest-bearing liabilities and identifies the change related to
outstanding balances (volume) and the change due to interest rate fluctuations
(rate) for the periods indicated. For purposes of this table, changes
attributable to both rate and volume that cannot be segregated have been
allocated to rate.

Provision for Credit Losses

         The provision for credit losses represents charges to income to bring
the total allowance for credit losses to a level deemed appropriate by
management based on such factors as Paradigm's historical loan loss experience,
industry diversification of the commercial loan portfolio, the amount of
nonperforming loans and related collateral, the volume, growth and composition
of the loan portfolio, current economic conditions that may affect the
borrower's ability to pay and the value of collateral, the evaluation of the
loan portfolio through the internal loan review process and other relevant
factors. See "Financial Condition - Allowance for Credit Losses" for more
information regarding Paradigm's allowance for credit losses.

                                       68



         The allowance for credit losses as a percentage of total loans
increased to 1.13% at March 31, 2002 from 0.66% at March 31, 2001 due primarily
to a contribution of $256,000 to Paradigm's credit loss reserve from the escrow
account established in 1999 in connection with the acquisition of Dayton State
Bank. In January 2002, a final allocation of the escrow funds was made to the
sellers based on the performance of certain loans acquired in the purchase of
Dayton State Bank. In accordance with the escrow agreement, the remaining escrow
funds were paid into Paradigm's credit loss reserve. As a result, Paradigm made
a provision for credit losses of $121,000 for the three months ended March 31,
2002, $94,000 less than the provision of $215,000 made for the same period in
2001.

         The provision for credit losses was $1.0 million for the year ended
December 31, 2001, 44.0% more than for 2000. Average total loans increased $23.4
million, or 19.1%, in 2001 compared with 2000. Management increased the
provision in 2001 primarily as a prudent response to loan growth and the general
economic downturn experienced in 2001. The provision was also increased to
provide for certain loans that increased in risk of loss during 2001. Future
provisions will be based on information then available.

Noninterest Income

         Paradigm's main source of noninterest income is service charges on
accounts, which are augmented by a variety of service fees, including ATM fees,
merchant and lockbox services, check cashing fees, collection and wire transfer
services and other fee services. Paradigm also realizes noninterest income from
occasional sales of loans, investment securities and fixed assets.

         Noninterest income decreased $456,000, or 29.2%, to $1.1 million for
the quarter ended March 31, 2002 compared with the same period in 2001. In the
first quarter of 2002, Paradigm recognized charges to other noninterest income
of $84,000 to write down real estate acquired by foreclosure, based on
reassessments of the value of that group of assets. In addition, in the first
quarter of 2001, Paradigm realized gains on sales of securities of $378,000 as
interest rate declines resulted in appreciation in its portfolio of available
for sale securities, a decrease of $172,000 compared with $206,000 in gains on
sales of securities in the first quarter of 2002, and reported other noninterest
income of $110,000 related to cash value of life insurance and recapture of
deferred compensation expense realized on the departure of certain officers from
Dayton State Bank. Further, due mainly to a decrease in customer usage of check
overdraft privileges, service charges and fee income decreased $71,000 in the
quarter ended March 31, 2002 compared with the same period in 2001.

         Noninterest income increased $1.2 million, or 32.2%, to $5.0 million
for the year ended December 31, 2001 compared with 2000. This increase was
mainly due to service charges on deposit accounts and other banking service
fees, plus gains on sales of securities. Customer service charges and other
service fees increased $633,000 and $96,000, respectively, in 2001 compared with
2000. Service charge and fee revenues increased due to growth in average
deposits in 2001, plus fee increases and increased customer activity. Paradigm
realized $450,000 in pre-tax gains on the sale of investment securities in 2001
due to appreciation in the investment portfolio that resulted from declining
interest rates. Paradigm realized a $105,000 gain on the sale of a cash flow
hedge in 2000. No other significant gains or losses on asset sales were realized
in 2001 or 2000.

         The following table presents the major categories of noninterest income
for the periods indicated:

         Total noninterest expenses decreased by $135,000, or 4.2%, for the
quarter ended March 31, 2002 compared with the same period in 2001. Non-staff
expenses decreased $124,000, or 7.1%, in the quarter ended March 31, 2002 versus
the same period in 2001. Outside service fees, which includes legal, accounting
and data processing fees, decreased $131,000 due mainly to bringing the majority
of Paradigm Bank's item processing activities in-house in the quarter ended
March 31, 2002. In accordance with Statement of Financial Accounting Standard
(SFAS) No. 142, Paradigm ceased amortizing its goodwill effective January 1,
2002. Other noninterest expenses grew $68,000 in the quarter ended March 31,
2002 compared with the same period in 2001, due mainly to higher internet
banking costs in conjunction with greater customer adoption, plus an increase in
other costs due to increases in activity volume.

         Total noninterest expenses increased $2.3 million, or 22.1%, to $12.8
million for 2001 compared with 2000 mainly due to the increase in the number of
branches, establishment of Paradigm's bank operations center and consolidation
activities related to the December 2000 merger of the banks. Salaries and
benefits increased $676,000, or 13.4%, in 2001 compared with 2000. The increase
was due mainly to additional staffing associated with opening three new banking
centers in August and December 2000 and May 2001.

         Non-staff expenses increased $1.6 million, or 30.2%, in 2001 versus
2000. Net occupancy costs were up $165,000 for 2001 versus 2000 due to opening
three new banking centers. Depreciation and amortization of fixed assets was
$402,000 higher for 2001 due to the new branches, the establishment of the bank
operations center, loan center and corporate office and data systems
improvements. Outside service fees increased $403,000 in 2001 due mainly to
higher item processing charges from the increased loan and deposit volume, plus
merger and conversion-related costs. Other noninterest expenses increased
$696,000 in 2001 compared with 2000, due mainly to higher printing costs,
telephone expense, postage and courier costs and a variety of other expense
increases associated with the new branches, name change, merger of the banks and
overall growth.

         Amortization of goodwill was $195,000 for 2001. Effective January 1,
2002, in accordance with Statement of Financial Accounting Standards (SFAS) No.
142, Paradigm no longer amortizes goodwill, but instead reviews goodwill at
least annually, or as impairment indicators arise.

Income Taxes

         The amount of income tax expense is determined by the amounts of
taxable income, tax-exempt income, nondeductible interest expense and other
nondeductible expenses. Income tax expense decreased $74,000 for the quarter
ended March 31, 2002 compared with the same period in 2001. Paradigm's effective
tax rate was 28.1% for the quarter ended March 31, 2002 versus 31.0% for the
same period in 2001. The lower tax expense and effective rate for the first
quarter 2002 was due to higher non-taxable interest income and lower income from
taxable sources.

         Due to the lower taxable income in 2001, income tax expense decreased
$695,000 for the year ended December 31, 2001 compared with 2000. Paradigm's
effective tax rate was 23.4% for 2001 versus 31.8% for 2000.

                                       70



The lower effective rate in 2001 is due to higher non-taxable interest income
and lower income from taxable sources.

         The effects of inflation on Paradigm's market areas and operating
results have been relatively modest for the past several years. Since
substantially all of our assets and liabilities are monetary in nature, such as
cash, securities, loans and deposits, their values are less sensitive to the
effects of inflation than to changing interest rates, which do not necessarily
change in accordance with inflation rates. Paradigm tries to manage the effect
of interest rate changes by managing the relationship between our interest rate
sensitive assets and liabilities.

Financial Condition

Cash, Cash Equivalents and Deposits in Financial Institutions

         Cash and cash equivalents includes cash in vaults, due from other
financial institutions and federal funds sold. Cash and cash equivalents were
$19.9 million at March 31, 2002 compared with $21.3 million at December 31,
2001. Cash and cash equivalents were $21.3 million at December 31, 2001 compared
with $15.8 million at December 31, 2000, an increase of $5.5 million in 2001.

         In the normal course of business, Paradigm maintains correspondent bank
accounts with various banks, which totaled $11.0 million at March 31, 2002 and
$10.0 million at December 31, 2001, including $10.0 million and $9.0 million,
respectively, with Frost Bank, its lead correspondent. Each correspondent bank
account is a demand account with normal bank correspondent services, including
sales and purchases of loan participations and federal funds. At March 31, 2002
and December 31, 2001, $4.3 million and $6.3 million, respectively, of cash
equivalents were in federal funds sold. Interest-earning deposits in financial
institutions were $5.3 million and $5.4 million at March 31, 2002 and December
31, 2001, respectively, including over $5.0 million with maturities of less than
one month.

Loan Portfolio

         The loan portfolio is the largest category of Paradigm's earning
assets. As a community banking organization, Paradigm focuses on providing loans
to businesses, consumers and other entities in our market areas.

         Total loans net of unearned income were $170.6 million at March 31,
2002, down $200,000 from December 31, 2001. At March 31, 2002, loans were 66.5%
of earning assets, compared with 65.9% at December 31, 2001.

         Total loans net of unearned income were $170.8 million at December 31,
2001, up $37.3 million, or 27.9%, from $133.5 million at December 31, 2000.
Loans at December 31, 2001 comprised 68.1% of earning assets, compared with
72.2% at December 31, 2000. The loan growth in 2001 was mainly due to the
business development achieved by the banking center presidents and lending
officers at our three new banking centers and our existing banking centers. Loan
growth in 2000 was due to a combination of business expansion in existing
banking centers and growth related to our Copperfield banking center opened in
August 2000. Much of the loan growth from December 31, 1998 to 1999 was due to
the purchase of Dayton State Bank.

     Our lending focus is on commercial mortgages, small and medium-sized
business loans and consumer loans. Paradigm offers a variety of commercial
lending products including term loans and lines of credit. A broad range of
short to medium-term commercial loans, mainly collateralized, is made available
to businesses for working capital (including inventory and receivables),
business expansion (including acquisitions of real estate and improvements) and
the purchase of equipment and machinery. The purpose of a particular loan
generally determines its structure.

     Loans from $150,000 to $500,000 are evaluated and acted upon by the credit
officer in conjunction with the division president or president of Paradigm
Bank. Loans above $500,000 must be approved by the Directors Loan Committee,
which meets weekly.

     Generally, Paradigm makes commercial loans in its primary market area and
underwrites them on the basis of the borrower's ability to service such debt
from income. Paradigm usually takes a collateral lien on any available real
estate, equipment or other assets owned by the borrower and obtains a personal
guaranty of the borrower. Short-term assets usually collateralize working
capital loans whereas term loans are usually collateralized by long-term assets.

     Paradigm makes commercial mortgage loans to finance the purchase of real
property that generally consists of real estate with completed structures.
Commercial mortgage loans are secured by first liens on real estate, typically
have variable interest rates and amortize over a 10 to 15 year period, with
maturities of 3 to 5 years. In underwriting commercial mortgage loans, Paradigm
considers the property's operating history, future operating projections,
current and projected occupancy, location and physical condition. The
underwriting analysis also includes credit verification, appraisals and a review
of the financial condition of the borrower.

     A portion of our lending activity is the origination of one to four-family
residential mortgage loans collateralized by owner-occupied properties located
in our market areas. Paradigm offers a variety of mortgage loan products that
generally are amortized over 5 to 25 years, with maturities typically not
exceeding five years. Loans

                                       72



collateralized by one to four-family residential real estate generally have been
originated in amounts of no more than 85% of appraised value or have mortgage
insurance. Paradigm requires mortgage title insurance and hazard insurance. All
loans in the one to four-family residential category were originated by us and
are typically on a balloon structure.

     Paradigm makes loans to finance the construction of residential and
nonresidential properties. Construction loans generally are secured by first
liens on real estate and have floating interest rates. Paradigm conducts
periodic inspections, either directly or through an agent, prior to approval of
periodic draws on these loans. Underwriting guidelines similar to those
described above are also used in our construction lending activities. In keeping
with our community-oriented focus, Paradigm provides construction and permanent
financing for churches and public entities located in our market areas.

     Consumer loans made by us include direct "A" credit automobile loans,
recreational vehicle loans, boat loans, home improvement loans, personal loans
(collateralized and uncollateralized) and deposit account collateralized loans.
The terms of these loans typically range from 12 to 120 months and vary based
upon the nature of collateral and size of loan.

     The contractual maturity ranges of the loan portfolio (excluding $21.9
million in installment loans net of discount at March 31, 2002) and the amount
of such loans with predetermined interest rates and floating rates in each
maturity range as of March 31, 2002 are summarized in the following table:

     Paradigm has adopted Statement of Financial Accounting Standards (SFAS) No.
114, "Accounting by Creditors for Impairment of a Loan", as amended by SFAS No.
118, "Accounting by Creditors for Impairment of a Loan-Income Recognition and
Disclosures". Under SFAS No. 114, as amended, a loan is considered impaired
based on current information and events, if it is probable that Paradigm will be
unable to collect the scheduled payments of principal or interest when due
according to the contractual terms of the loan agreement. The fair value of
impaired loans is based on either the present value of expected future cash
flows discounted at the loan's effective interest rate or the loan's observable
market price or the fair value of the collateral if the loan is
collateral-dependent. The implementation of SFAS Nos. 114 and 118 did not have a
material adverse effect on our financial statements.

     At March 31, 2002 and December 31, 2001, Paradigm had outstanding and
unfunded standby letters of credit, which are primarily cash secured, of about
$370,000 and $373,000, respectively. Paradigm also had unfunded loan commitments
at March 31, 2002 of $25.8 million, of which Paradigm considers about 33% likely
to be funded in 2002.

     Paradigm accrues interest on its performing loans daily. Interest is
computed using the simple interest method, which recognizes that as principal
balances are reduced during the term of the loan, a smaller portion of each loan
payment represents interest earned on the balance. Paradigm often charges points
and fees on the origination of certain real estate and construction loans.
Paradigm complies with appropriate accounting principles for recognizing income
on fees and points.

Nonperforming Assets

     Nonperforming assets include nonaccruing loans, loans past due 90 days or
more, and real estate acquired by foreclosure. Paradigm uses a number of
procedures to maintain the overall quality of our loan portfolio. Paradigm has
established underwriting guidelines for officers, and monitors delinquency
levels for any adverse trends. Paradigm also has a third party perform quarterly
loan reviews to help maintain asset quality.

     For potential problem loans, the borrower's overall financial condition is
evaluated to determine the need for possible write-downs or additions to the
allowance for credit losses. Paradigm places a loan on nonaccrual status and
stops accruing interest income when, in the opinion of management, the
borrower's financial condition is such that collection of interest is doubtful.
This assessment is based on criteria such as payments past due or defaulted,

                                       73



asset deterioration, decline in cash flow, operating losses, declining sales,
bankruptcy or other financial indicators. Paradigm usually places a loan on
non-accrual status and stops accruing interest when the payment of principal or
interest is delinquent for 90 days, or earlier in some cases, unless the loan is
in the process of collection and the underlying collateral fully supports the
carrying value of the loan. At March 31, 2002, nonperforming assets were $1.5
million, up from $1.4 million at December 31, 2001.

     Paradigm records real estate acquired by foreclosure at the lesser of the
outstanding loan balance or the fair value of the real estate at the time of
foreclosure, less estimated costs to sell. Paradigm requires appraisals on loans
secured by real estate.

     The following table presents information regarding nonperforming assets at

Allowance for Credit Losses

     The allowance for credit losses is a reserve established through charges to
earnings in the form of a provision for credit losses. Management has
established an allowance for credit losses that it believes is adequate for
estimated losses in the loan portfolio. Based on an evaluation of the loan
portfolio, management presents a monthly review of the allowance for credit
losses to the bank's board of directors, indicating any change in the allowance
since the last review and any recommendations for adjustments in the allowance.

     In evaluating the adequacy of the allowance for credit losses, management
considers the diversification by industry of the commercial loan portfolio, the
effect of changes in the local real estate market on collateral values, the
results of recent regulatory examinations, the effects on the loan portfolio of
current economic indicators and their probable impact on borrowers, the amount
of charge-offs for the period, the amount of nonperforming loans and related
collateral security, and the evaluation of the loan portfolio by the internal
loan review process. Charge-offs are made when loans are deemed to be
uncollectible.

     Paradigm follows a loan review program incorporating both internal and
external reviews to evaluate the credit risk in the loan portfolio. Under the
loan review process, Paradigm maintains an internally classified loan list that,
along with the delinquency loan list, helps management assess the overall
quality of the loan portfolio and the adequacy of the allowance for credit
losses. Loans classified as substandard have clear and defined weaknesses such
as highly leveraged position, unfavorable financial ratios, uncertain repayment
sources or poor financial condition, which may jeopardize recoverability of the
debt. Loans classified as doubtful have characteristics similar to substandard
loans but with an increased risk that a loss may occur or a portion of the loan
may require a charge-off if liquidated currently. Loans classified as loss are
in the process of being charged off.

     Paradigm also maintains a watch list of loans that have one or more
deficiencies that require attention in the short term, or that have pertinent
financial ratios that have weakened such that more frequent monitoring is
warranted. These loans do not have all of the characteristics of a loan
classified as substandard or doubtful, but do show weakened elements compared to
a satisfactory credit. Paradigm monitors these loans to assist in assessing the
adequacy of the allowance for credit losses.

     To determine the adequacy of the allowance for credit losses, management
considers the risk classification (based on grade) or delinquency status of
loans and other factors, such as collateral value, portfolio composition,
economic trends and the financial strength of borrowers. Paradigm establishes
specific allowances for loans that Paradigm believes require reserves greater
than those allocated according to their classification or delinquent status.
Paradigm then charges to operations a provision for credit losses to maintain
the allowance at an adequate level determined by the foregoing methodology.

                                       74



     Paradigm incorporates and analyzes the following factors in establishing
the amount in its allowance for credit losses. A loan grade, which is assigned
to each loan, is based on an analysis of the following general credit criteria:

     .    character (borrower, principals, guarantors, customers, commitments
          kept);

     .    conditions (business, economic, industry, political);

     .    management (quality, experience, succession, knowledge, reputation,
          planning);

     .    accounting and control systems (confidence, inventory, quality,
          records, audits);

     .    financial condition (leverage, trends, history, agency reports, prior
          payment experience, compensating balances);

     .    repayment ability (cash flow, capital replacement needs,
          predictability, reliability, access to outside capital);

     .    structure (appropriate type and maturity - term or revolving, loan
          agreements, borrowing base reports, controls, monitoring ease,
          amortization period, clean-up); and

     .    collateral (type, control, lien perfection, location, liquidity,
          marketability, valuation, insurance).

     It is Paradigm Bank's policy to diversify credit risk and to make credit
available to a broad segment of Paradigm Bank's target market. Accordingly,
Paradigm tries to avoid excessive credit extensions to any one borrower or
related groups of borrowers. Additionally, Paradigm Bank is subject to certain
statutory legal lending limits.

   Through the loan review process, Paradigm assigns one of the following loan
grades to each loan:

     Grade 1 loans are those loans that expose Paradigm Bank to the least
possible credit risk. This grade is associated with individuals or companies
with unquestioned financial strength and substantial and reliable excess cash
flows for debt service. It is also associated with loans that are secured by
appropriately margined liquid collateral.

     Grade 2 loans represent excellent credit risk but are somewhat below a
Grade 1 credit.

     Grade 3 loans represent reasonable and satisfactory credit risk for
Paradigm Bank. Generally these loans will carry additional credit risk compared
to Grades 1 and 2 due to the financial strength of the borrower, type of
collateral pledged, lower but acceptable levels of liquidity, and higher
leverage.

     Grade 4 loans include real estate secured loans within Loan Policy
underwriting guidelines, which do not meet qualifications for Grade 3 and
borrowers with acceptable liquidity, cash flow and net worth but not significant
enough to qualify for Grade 3. This grade includes most commercial loans secured
by accounts receivable, inventory, machinery, equipment, furniture, and
fixtures, and most real estate construction loans.

     Grade 5 (includes Pass-Watch loans) are those loans that appear to have
been prudently underwritten and are generally performing, but the lending
officer is concerned that a negative trend or bias may be developing.

     Loans in the Pass-Watch grade category will also include all loans better
than Grade 6 that are more than thirty (30) days past due (principal or
interest), including all installment loans that are two (2) or more payments
past due, and loans with significant credit and/or collateral exceptions that
have remained uncorrected for more than 60 days.

     Grade 6 loans are currently protected, but potentially weak credits. The
deficiencies, if not checked and corrected, may weaken the loan or inadequately
protect the bank's position at some future date. Grade 6 loans are believed to
be potential problems that warrant more than the usual management attention, but
don't quite justify a classification of substandard. The risk may be relatively
minor, yet is unwarranted in light of the circumstances surrounding the credit.

                                       75



     Grade 7, or substandard loans, involve more than a normal degree of risk
and are inadequately protected by the solid worth and paying ability of the
borrower. They represent unacceptable risk to Paradigm Bank. The credits may be
performing or not, but the weaknesses in the credit may have placed the agreed
upon repayment program in jeopardy. Restructuring of the loan may be necessary
since the borrower is unable to meet originally agreed upon loan terms.
Additional collateral is often required. Although there may be no identifiable
loss in this type of loan, usually due to excess collateral coverage, the loan
is not expected to liquidate according to its terms and collateral liquidation
or other secondary or tertiary repayment sources, including guarantors, will
likely be utilized. The probability of relying on legal remedies is high. If
SFAS 114 or other analysis suggests the loan is impaired, a portion of the
allowance for credit losses may be specifically allocated to the credit.

     Grade 8 loans are doubtful. Grade 8 loans have all the weaknesses of a
substandard loan, but on the basis of currently existing information, collection
in full is unlikely. The probability of some loss is extremely high, but because
of important and reasonably specific pending factors that may work toward
strengthening the loan, loss classification is deferred until a more exact
status may be determined. Pending factors may include a proposed merger,
acquisition, or liquidation, capital injection, additional collateral, or
outside refinancing. The pending factors should be verifiable and likely to be
completed in a reasonably short period. All loans in Grade 8 are on nonaccrual
status.

     Grade 9 represents loss loans that are considered uncollectible or of such
little value that their continuance as active assets of the bank is not
warranted. This classification does not mean that the loan has no recovery or
salvage value, but rather that it is not practical or desirable to defer writing
it off as an asset.

     All loans assigned a grade of 5 through 9 are placed on the Watch List. The
Watch List is provided to the Directors' Loan Committee monthly.

     In connection with the acquisition of Dayton State Bank, about $524,000 of
the purchase price was escrowed as a reserve for the performance of 29 specified
loans. A specific amount of the aggregate reserve was allocated to each loan.
This reserve was held in escrow in an account at the bank. Pursuant to the
escrow agreement, semiannual disbursements of the reserve were made to the
former shareholders of Dayton State Bank only if a specific loan was paid-off or
it was deemed satisfactory by Paradigm. At December 31, 2001, the remaining
escrow balance was $468,000.

     The escrow period was completed in December 2001. In early 2002, escrowed
funds totaling $212,000 and due to the former Dayton State Bank shareholders
were paid or allocated to them. The remainder of $256,000 was paid into Paradigm
Bank's loan loss reserve as stipulated in the escrow agreement. Of this
$256,000, $91,000 was allocated to specific loans which had already been charged
off, and was therefore recorded as recoveries among the various categories in
the first quarter of 2002. The remaining $165,000 was recorded as a special
contribution to the reserve in the first quarter of 2002.

     For the quarter ended March 31, 2002, net recoveries were $73,000,
primarily due to the $91,000 in recoveries recorded from the escrow
contribution. At March 31, 2002, the allowance for credit losses was 1.13% of
total loans, up from 0.92% at December 31, 2001. This increase was mainly due to
the special contribution from the escrow funds from the Dayton State Bank
purchase.

     For 2001, net charge-offs totaled $576,000, or 0.40% of average loans
outstanding for the period, compared with charge-offs of $245,000, or 0.20% of
average loans outstanding for 2000. The increase in net charge-offs was due
primarily to the charge-off of $327,000 on one loan. During 2001, Paradigm
recorded a provision for credit losses of $1.0 million compared with $701,000 in
2000. At December 31, 2001, the allowance for credit losses totaled $1.6
million, or 0.92% of total loans, compared with $1.1 million, or 0.85% of total
loans, at December 31, 2000.

     The increase in average loans and the related provision, charge offs and
recoveries, and allowance for credit losses from 1999 to 2000 was due mainly to
the purchase of Dayton State Bank in December 1999.

     When management can identify specific loans or groups of loans requiring
specific amounts of reserve, portions of the allowance for credit losses are
specifically allocated to those loans. Federal and state bank regulators also
require that a bank maintain an allowance for credit losses that is sufficient
to absorb an estimated amount of unidentified potential losses based on
management's perception of economic conditions, loan portfolio growth,
historical charge-off experience, exposure concentrations, the results of
regulatory examinations, evaluations by independent loan review contractors, the
review by Paradigm's independent auditors and other factors. Not all of the
amounts shown in the table above as applicable to specific categories of loans
are allocated to specific loans; but rather they reflect management's evaluation
of the relative risks inherent in the loan categories indicated based on the
above factors. Management believes that maintaining unallocated reserves is
prudent and consistent with regulatory requirements. Management believes that
the allowance for credit losses at March 31, 2002 is adequate to cover losses
inherent in the portfolio at that date. There can be no assurance, however, that
Paradigm will not sustain losses in future periods that could be substantial in
relation to the allowance at March 31, 2002.

Investment Portfolio

     Paradigm has adopted SFAS No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." At the date of purchase, Paradigm is required to
classify each debt or equity security into one of three categories: held to
maturity (HTM), trading, or available for sale (AFS). Securities are classified
as HTM and measured at amortized cost in the financial statements only if
management has the positive intent and ability to hold them to maturity.
Securities bought mainly to sell in the near term are classified as trading and
measured at fair value in the financial statements, with unrealized gains and
losses included in earnings. Investments not classified as either HTM or trading
are classified as AFS and measured at fair value in the financial statements,
with unrealized gains and losses reported, net of tax, as a separate component
of other comprehensive income in shareholders' equity until realized.

       Paradigm uses its securities portfolio as a source of income and
liquidity, to manage interest rate risk and to provide collateral for municipal
pledging requirements. The portfolio is typically invested in low risk assets,
usually securities rated AA or higher or backed by the United States government.
Investments are managed by Paradigm Bank's Asset and Liability Committee based
on policies set by Paradigm Bank's board of directors.

       At March 31, 2002, investment securities totaled $43.3 million, down from
$43.7 million at December 31, 2001. During the first quarter of 2002, Paradigm
sold some of its investments to realize profits in the available for sale
portfolio that had accrued due to the interest rate decreases in 2001.
Securities were 16.9% of total assets at both March 31, 2002 and December 31,
2001.

       At December 31, 2001, investment securities totaled $43.7 million, down
from $46.8 million at December 31, 2000. Due to interest rate decreases, most of
our investments in callable securities were called in 2001. Paradigm also sold
some of our investments to realize profits in the available for sale portfolio
that had accrued due to the interest rate decreases in 2001. Securities were
16.8% and 21.7% of total assets at December 31, 2001 and 2000, respectively. The
average yield on securities for 2001 was 5.63%, compared with 6.07% for 2000.

         Mortgage-backed securities are pools of real estate mortgages and are
mainly issued by federal agencies such as the Federal National Mortgage
Association and Federal Home Loan Mortgage Corporation. They are deemed to have
high credit ratings, and the minimum regular monthly cash flows of principal and
interest are guaranteed by the issuing agencies. Contractual maturity of
mortgage-backed securities is not a reliable indicator of their expected life
because borrowers have the right to prepay their obligations at any time.

         At December 31, 2001, 88% of the mortgage-backed securities Paradigm
held had contractual final maturities of more than 10 years. However, unlike
U.S. Treasury and U.S. government agency securities, which have a lump sum
payment at maturity, mortgage-backed securities provide cash flows from regular
principal and interest payments and principal prepayments throughout the lives
of the securities. Mortgage-backed securities bought at a premium will generally
suffer decreasing net yields as interest rates drop because homeowners tend to
refinance their mortgages, thus shortening the premium amortization period.
Mortgage-backed securities bought at a discount will generally provide higher
yields in a decreasing rate environment. As interest rates rise, the opposite
will generally be true. During a period of increasing interest rates, fixed rate
mortgage-backed securities do not tend to experience heavy prepayments of
principal, and consequently, the average life of this security will not be
unduly shortened. If interest rates fall, prepayments will increase.

Deposits

         Paradigm relies mainly on its deposits to fund its lending and
investing activities. Deposits also generate service charges and lead to other
fee income. Paradigm offers a variety of deposit accounts with a wide range of
interest rates and terms that are competitive in our market area. Our deposit
liabilities include demand, savings, money market and certificates of deposit.
Paradigm relies mainly on strong customer relationships and service and
competitive pricing to attract and retain these deposits. Paradigm does not have
or accept any brokered deposits.

         Total deposits at March 31, 2002 were $230.3 million, down about $2.1
million from December 31, 2001. Total deposits at December 31, 2001 were $232.4
million compared with $188.0 million at December 31, 2000, an increase of $44.4
million, or 23.6%. The increase in deposits in 2001 was due to the development
of our three new branches, growth at existing branches and an economic trend
that fed deposit growth in banks as investors sought security from riskier
deposit and investment options. Noninterest-bearing deposits were 36.1% of total
deposits at year-end 2001 compared with 37.1% of total deposits for 2000.

         The increase in average deposits from 1999 to 2000 was due mainly to
the purchase of Dayton State Bank in December 1999.

Other Borrowings

         Deposits are the main source of funds for Paradigm's lending and
investing activities. Occasionally, Paradigm may obtain additional funds from
correspondent banks, the Federal Home Loan Bank, or the purchase of federal
funds. At March 31, 2002 and December 31, 2001, Paradigm had no funds borrowed
from any of those sources. In 2001, Paradigm entered into an agreement with
another commercial bank to borrow up to $500,000 under a revolving line of
credit. At March 31, 2002 and at December 31, 2001, Paradigm had no borrowings
under this line.

Trust Preferred Securities

         During the first quarter of 2001, Paradigm formed a new, wholly-owned
Delaware statutory business trust, Paradigm Capital Trust II (Trust II), which
issued $6.0 million of floating rate preferred securities and $186,000 of common
stock. Paradigm purchased the common stock, and third party investors purchased
the preferred securities. Trust II invested the proceeds in $6,186,000 of
Paradigm's floating rate junior subordinated debentures due February 20, 2031
(debentures). These debentures, which are the only assets of the trust, are
subordinate and junior in right of payment to all present and future senior
indebtedness (as defined in the Indenture dated February 20, 2001) of Paradigm.
Paradigm has fully and unconditionally guaranteed the trust's obligations under
the preferred securities.

         For financial reporting purposes, Trust II is treated as a subsidiary
of Paradigm and consolidated in the corporate financial statements. The
preferred securities are eligible to be treated as Tier 1 capital by the Federal
Reserve Board, within certain constraints. The treatment of the preferred
securities as Tier 1 capital and the deductibility of interest on the debentures
for federal income tax purposes made this an attractive way to raise capital.
Paradigm received proceeds of $6.0 million, of which $5.2 million was used to
redeem all of Paradigm's outstanding 10.375% subordinated debentures, including
accrued interest of $77,000, and the remainder was used to pay expenses
associated with the offering and for general corporate purposes.

         The debentures accrue interest at a floating rate that adjusts
quarterly based on the 90-day LIBOR rate. The quarterly distributions on the
trust preferred securities are paid at the same rate that interest is paid on
the debentures. For the quarter ended December 31, 2001, the rate on the
debentures was 7.65%. For the quarter ending March 31, 2002, the rate was 6.37%,
a decrease of $16,000 compared with the quarter ended December 31, 2001. For the
year ended December 31, 2001, the effective interest rate on the debentures,
including amortization of issuance costs, was 8.99%.

Liquidity

         Cash and cash equivalents decreased $1.4 million in the quarter ended
March 31, 2002 compared with an increase of $15.7 million for the same period in
2001.

         Paradigm generated cash from operations of $363,000 in the first
quarter of 2002 compared with $910,000 in the first quarter of 2001. The
decrease was due mainly to the timing of payments of accrued interest receivable
and payable.

         Paradigm realized cash from investing activities of $797,000 in the
first quarter of 2002 compared with $10.1 million in the first quarter of 2001.
Paradigm invested $81,000 of cash in fixed assets in 2002, as it was not
building or remodeling any new banking centers. Paradigm spent $631,000 on fixed
assets in the first quarter of 2001, mainly to complete its Gladebrook banking
center, which opened in December 2000, and to begin work on its Galveston
banking center, which opened in May 2001.

         Financing activities used $2.6 million in the quarter ended March 31,
2002 compared with providing $4.7 million for the same period in 2001. Deposits
decreased $2.1 million in the first quarter of 2002. Deposits had increased $5.3
million in the first quarter of 2001, due to growth in Paradigm's new and
existing banking centers, combined with a general trend for deposit growth at
banks as depositors sought security from more volatile investment options.

         Cash and cash equivalents increased $5.6 million in 2001 compared with
a decrease of $10.8 million in 2000.

         Paradigm generated cash from operations of $2.7 million in 2001
compared with $3.6 million in 2000. The decrease was due mainly to $1.1 million
less net income in 2001.

         Paradigm used $40.2 million of cash for investing activities in 2001
compared with $15.8 million in 2000. In 2001, loan growth consumed $37.9 million
and the net increase in securities and interest-bearing deposits used $494,000.
In 2000, loan growth used $22.5 million and investments in securities and
interest-bearing deposits provided $8.9 million. Paradigm invested about $1.8
million of cash in fixed assets in 2001, including completion of its Gladebrook
banking center and corporate offices, its Galveston banking center and
improvement of its computer systems. Paradigm spent $2.1 million on fixed assets
in 2000, including the development of its Copperfield and Gladebrook banking
centers and expansion of its item and data processing systems.

         Financing activities provided $43.1 million in 2001 versus $1.4 million
in 2000. Increased deposits provided $44.3 million in 2001 compared with $6.0
million in 2000. The deposit growth in 2001 was due mainly to growth in
Paradigm's new and existing banking centers, combined with a general trend for
deposit growth at banks as depositors sought security from more volatile
investment options.

         Paradigm maintains liquidity in the form of readily marketable
investment securities (i.e., U.S. Treasury bills), demand deposits and
short-term time deposits with commercial banks, vault cash and federal funds
sold. While the minimum liquidity requirement for banks is determined by federal
bank regulatory agencies as a percentage of deposit liabilities, Paradigm's
management monitors liquidity requirements as warranted by interest rate trends,
changes in the economy and the scheduled maturity and interest rate sensitivity
of the investment and loan portfolios and deposit liabilities. Paradigm also has
correspondent relationships with other banks in order to sell loans or purchase
overnight funds should additional liquidity be needed. Paradigm is a shareholder
of the Federal Home Loan Bank, which enables it to borrow for an extended
period. Paradigm believes its present position is adequate to meet its liquidity
needs in the near future.

Interest Rate Sensitivity

         Paradigm's Asset, Liability and Funds Management Policy provides
management guidelines for effective funds management, and Paradigm uses a
measurement system for monitoring our net interest rate sensitivity position.
Paradigm manages our sensitivity position within established guidelines.
Interest rate risk is managed by the Asset and Liability Committee (ALCO)
composed of senior officers and directors in accordance with policies approved
by the board of directors of Paradigm Bank.

         The ALCO formulates strategies based on appropriate levels of interest
risk. To determine the appropriate level of interest rate risk, the ALCO
considers the effect on earnings and capital of potential changes in interest

                                       82



rates, economic conditions, liquidity, business strategies and other factors.
The ALCO meets regularly to review, among other things, the sensitivity of
assets and liabilities to interest rate changes, the book and market values of
assets and liabilities, unrealized gains and losses, purchase and sale
activities, loan commitments, the maturities of investments and borrowing. The
ALCO also reviews liquidity, cash flow flexibility, maturities of deposits and
consumer and commercial deposit activity. Management uses two methods to manage
interest rate risk: (i) an analysis of relationships between interest-earning
assets and interest-bearing liabilities, and (ii) an interest rate shock
simulation model.

         An interest rate sensitive asset or liability is one that, within a
defined time period, either matures or experiences an interest rate change in
line with general market interest rates. Interest rate risk is managed by
analyzing the maturity and repricing relationships between interest-earning
assets and interest-bearing liabilities at specific dates (GAP analysis) and by
analyzing the effects of interest rate changes on net interest income over
specific periods by projecting the performance of the mix of assets and
liabilities in varied interest rate environments. Interest rate sensitivity
reflects the potential effect on net interest income of a change in interest
rates. A company is asset sensitive, or has a positive GAP, when the amount of
its interest-earning assets maturing or repricing within that time period
exceeds the amount of its interest-bearing liabilities also maturing or
repricing within that period. Conversely, a company is liability sensitive, or
has a negative GAP, when the amount of its interest-earning liabilities maturing
or repricing in the specified period exceeds the amount of its interest-earning
assets maturing or repricing in that period. In a period of rising interest
rates, a negative GAP tends to lower net interest income, while a positive GAP
would tend to increase interest income. In a period of falling interest rates, a
negative GAP tends to increase net interest income, while a positive GAP tends
to decrease interest income.

         The following table shows Paradigm's interest rate sensitivity analysis
at March 31, 2002:

         Shortcomings are inherent in GAP analysis to the extent that certain
assets and liabilities may not change proportionally as interest rates change.
To supplement GAP analysis, Paradigm uses an interest rate risk simulation model
and shock analysis to test the interest rate sensitivity of net interest income
and the balance sheet. Contractual maturities and repricing opportunities of
loans are incorporated in the model, as are prepayment assumptions, maturity
data and call options within the investment portfolio. Assumptions based on past
experience are incorporated into the model for nonmaturity deposit accounts.

         Based on Paradigm's March 31, 2002 simulation analysis, Paradigm
estimates that a 200 basis point rise in rates over the next 12 months would
increase net interest income $728,000, or 6.7%, and a 200 basis point decline
would reduce net interest income by $687,000, or 6.3%. These estimates are based
on the timing of interest rate changes for liabilities, mainly deposits, and
assets, mainly loans. This assumption incorporated in the simulation model is
generally not fully reflected in a GAP analysis.

         Paradigm's primary market risk is interest rate volatility. Interest
rate changes ultimately affect income and expense from most of our assets and
liabilities, and the market value of interest-earning assets and
interest-bearing liabilities that do not have very short-term maturities.
Paradigm is not subject to foreign exchange or commodity price risk, and does
not own any trading assets.

         Paradigm reviews its exposure to market risk regularly. Interest rate
risk is the potential of economic losses due to future interest rate changes
that reduce future net interest income and current fair market values.
Paradigm's

                                       83



goal is to measure the effect on net interest income and to manage its assets
and liabilities to minimize the inherent risk while maximizing income.

         Paradigm applies a market value (MV) methodology to gauge its interest
rate risk exposure as derived from its simulation model. Generally, MV is the
value of incoming cash flows on interest-earning assets and other investments
less the value of the outgoing cash flows on interest-bearing liabilities. The
methodology attempts to quantify interest rate risk by measuring the change in
MV that would result from a 200 basis point change in market interest rates.

         At March 31, 2002, Paradigm estimated that its MV would increase 6.1%
over the next twelve months if a 200 basis point increase in market interest
rates occurs. Paradigm estimates that its MV would decrease 10.0% over the next
twelve months if there were a 200 basis point decrease in market rates over that
year.

         Management believes that the MV method overcomes three shortcomings of
the typical maturity GAP method. First, it does not use arbitrary repricing
intervals and accounts for all expected future cash flows. Second, because the
MV method projects cash flows of each financial instrument under different
interest rate environments, it can incorporate the effect of embedded options on
an institution's interest rate risk exposure. Third, it allows interest rates on
different instruments to change by varying amounts in response to changes in
market interest rates, providing more accurate cash flow estimates.

         As with any method of gauging interest rate risk, however, there are
certain shortcomings in the MV method. The model assumes interest rate changes
are instantaneous parallel shifts in the yield curve. In reality, rate changes
are rarely instantaneous. The simplifying assumption that short-term and
long-term rates changed by the same degree may also misstate historic rate
patterns, which rarely show parallel yield curve shifts. Further, the model
assumes that certain assets and liabilities of similar maturity or repricing
will react identically to changes in rates. In reality, the market value of
certain types of financial instruments may adjust in anticipation of changes in
market rates, while any adjustment in the valuation of other types of financial
instruments may lag behind the change in general market rates. Also, the MV
method does not reflect the full effect of contractual restrictions on changes
in rates for certain assets, such as adjustable rate loans. When interest rates
change, actual loan prepayments and actual early withdrawals from certificates
of deposit may deviate significantly from the assumptions used in the model.
Finally, this method does not measure or reflect the effect that higher rates
may have on the ability of adjustable-rate loan clients to service their debt.
All of these factors are considered in monitoring Paradigm's exposure to
interest rate risk.

         In July 2000, Paradigm purchased an interest rate floor to hedge
against the effect of future interest rate declines for our portfolio of
floating rate loans. Paradigm paid $195,000 for the floor, which would have paid
us seven quarterly payments based on a notional amount of $30.0 million if the
LIBOR interest rate were below 7.0% from October 25, 2000 through April 25,
2002. This floor was accounted for as a cash flow hedge in accordance with SFAS
No.133, "Accounting for Derivative Instruments and Hedging Activities" as
amended by SFAS No. 138, "Accounting for Certain Derivative Instruments and
Certain Hedging Activities." To capitalize on a market fluctuation, the hedge
was sold in the last quarter of 2000, providing a pre-tax gain of $105,000 in
sale of securities.

Capital Resources

         Capital management consists of providing equity to support both current
and future operations. Paradigm is subject to capital adequacy requirements
imposed by the Board of Governors of the Federal Reserve and Paradigm Bank is
subject to capital adequacy requirements imposed by the FDIC. Both the Federal
Reserve and the FDIC have adopted risk-based capital requirements for assessing
financial holding company and bank capital adequacy. These standards define
capital and establish minimum capital requirements in relation to assets and
off-balance sheet exposure, adjusted for credit risk. The risk-based capital
standards currently in effect are designed to make regulatory capital
requirements more sensitive to differences in risk profiles among financial
holding companies and banks, to account for off-balance sheet exposure and to
minimize disincentives for holding liquid assets. Assets and off-balance sheet
items are assigned to broad risk categories, each with appropriate relative risk
weights. The resulting capital ratios represent capital as a percentage of total
risk-weighted assets and off-balance sheet items.

         The risk-based capital standards of the Federal Reserve require
financial holding companies to have Tier 1 capital of at least 4.0% and total
risk-based capital (Tier 1 and Tier 2) of at least 8.0% of total risk-adjusted
assets. Tier 1 capital generally includes common shareholders' equity and
qualifying perpetual preferred stock together with

                                       84



related surpluses and retained earnings, less deductions for goodwill and
various other intangibles. Tier 2 capital may consist of a limited amount of
intermediate-term preferred stock, a limited amount of term subordinated debt,
certain hybrid capital instruments and other debt securities, perpetual
preferred stock not qualifying as Tier 1 capital, and a limited amount of the
general valuation allowance for loan losses. The sum of Tier 1 capital and Tier
2 capital is total risk-based capital.

         The Federal Reserve has also adopted guidelines which supplement the
risk-based capital guidelines with a minimum ratio of Tier 1 capital to average
total consolidated assets (leverage ratio) of 3.0% for institutions with well
diversified risk, including no undue interest rate exposure; excellent asset
quality; high liquidity; good earnings; and that are generally considered to be
strong banking organizations, rated composite 1 under applicable federal
guidelines, and that are not experiencing or anticipating significant growth.
Other banking organizations are required to maintain a leverage ratio of at
least 4.0%. These rules further provide that banking organizations experiencing
internal growth or making acquisitions will be expected to maintain capital
positions substantially above the minimum supervisory levels and comparable to
peer group averages, without significant reliance on intangible assets.

         Pursuant to the Federal Deposit Insurance Corporation Improvement Act
(FDICIA), each federal banking agency revised its risk-based capital standards
to ensure that those standards take adequate account of interest rate risk,
concentration of credit risk and the risks of nontraditional activities, as well
as reflect the actual performance and expected risk of loss on multifamily
mortgages. Paradigm Bank is subject to capital adequacy guidelines of the FDIC
that are substantially similar to the Federal Reserve's guidelines. Also
pursuant to FDICIA, the FDIC has promulgated regulations setting the levels at
which an insured institution such as the bank would be considered "well
capitalized," "adequately capitalized," "undercapitalized," "significantly
undercapitalized" and "critically undercapitalized." Paradigm Bank is classified
"well capitalized" for purposes of the FDIC's prompt corrective action
regulations.

         Total stockholders' equity was $18.1 million at December 31, 2001
compared with $17.3 million at December 31, 2000, an increase of $800,000, or
4.6%. The increase was due to Paradigm's earnings net of dividends paid and the
change in accumulated gain on securities available for sale. At March 31, 2002,
total shareholders' equity had increased to about $18.4 million due to retained
earnings for the quarter less a reduction in the accumulated gain on securities
available for sale.

         The following table provides a comparison of Paradigm's and Paradigm
Bank's leverage and risk-weighted capital ratios at March 31, 2002 and December

                              BUSINESS OF PARADIGM

General

         Paradigm is a financial holding company headquartered in Houston,
Texas. Paradigm was formed as a bank holding company for Paradigm Bank Texas
under the laws of the State of Texas in 1996, and elected to become a financial
holding company in 2000.

         Paradigm provides commercial and retail banking services from the
community banking offices of Paradigm Bank Texas, its wholly-owned subsidiary, a
Texas banking association headquartered in Houston. Paradigm Bank was originally
chartered in 1980 as Bank of Cypress Trails and renamed Woodcreek Bank when its
principal location was established in the Woodcreek area of north Houston. In
1997, Paradigm acquired First National Bank of Dayton, which was merged into
Woodcreek Bank. In October 2000, Woodcreek Bank changed its name to Paradigm
Bank Texas to reflect its greater geographic and market development.

         In December 1999, Paradigm acquired Dayton State Bank, a Texas banking
association with locations in Dayton, Winnie and Mt. Belvieu. Dayton State Bank
was operated as a separate bank for one year, and merged into Paradigm Bank
Texas in December 2000.

         Paradigm has grown by increasing loans and deposits at existing banking
centers, by acquiring two existing community banks and by opening new banking
centers. Paradigm Bank Texas operates 11 community banking centers (branches)
serving Texas, six in the greater Houston metropolitan area, two in Dayton and
one each in Winnie, Galveston and Mt. Belvieu. Paradigm opened its Galveston
branch in May 2001, and two new Houston branches in August and December 2000.
Between 1991 and 2000, Paradigm opened six new branches in Houston. In November
2001, Paradigm closed one Houston branch in the Cy-Fair area and transferred its
business and staff to its nearby Gladebrook location.

Bank Activities

         Paradigm operates with a community banking philosophy emphasizing
long-term customer relationships based on service and convenience. A key element
of this community banking approach is our banking center model, which Paradigm
implemented in 1998. Each branch is a full-service banking center led by a
banking center president focused on serving local community businesses and
consumers. Paradigm entrusts its banking center presidents with authority and
flexibility for product pricing, customer service and decision-making within
general parameters established by management.

         Paradigm offers a variety of traditional loan and deposit products to
its customers, which are mainly small and medium-size businesses and individual
consumers. For businesses, Paradigm provides term loans, lines of credit and
loans for working capital, business expansion and the purchase of equipment and
machinery, interim construction loans for builders and owner occupied commercial
real estate loans. Paradigm offers consumers a variety of products and services,
including automobile loans, home equity loans and debit cards. Paradigm offers
all of its customers a full array of cash management, Internet banking and
traditional deposit services.

Competition

         The banking business is highly competitive, with Paradigm's
profitability dependent on the ability to compete in its market areas. Paradigm
competes with other commercial banks, savings banks, savings and loan
associations, credit unions, finance companies, mutual funds, insurance
companies, brokerage and investment banking firms, asset-based nonbank lenders
and certain other nonfinancial entities, including retail stores that offer
credit programs, and certain governmental organizations which may offer more
favorable financing than Paradigm offers. Paradigm expects competition from both
financial and nonfinancial institutions to continue. Recently enacted federal
legislation eased burdens previously imposed on banks, securities firms,
insurance companies, credit unions and other financial service providers. As a
result, it may be easier for nonbank institutions to compete directly with
Paradigm.

         Paradigm has been able to compete effectively in its market areas by
providing responsive community banking, experienced community lending officers
and a full range of commercial and retail banking services. The greater Houston
area is marked by a large number of local, regional and national financial
institutions. The Galveston, Dayton, Winnie and Mt. Belvieu markets are mainly
served by a smaller number of local competitors.

                                       86



These local competitors compete in Paradigm's customer niche on loan and deposit
pricing, related terms, traditional services offered, less traditional services
such as insurance and brokerage offerings, branch locations, advertising and
promotional programs, and by developing customer relationships.

         Paradigm's competitive edge is built upon developing strong customer
relationships through fast and effective service, and on being more responsive
to the needs and wants of the customer than other institutions. This service
includes loan and deposit pricing within Paradigm's profitability models, being
faster than the competition in providing loan responses and other services,
building a network of convenient locations and providing the banking services
most important to its customers.

Properties

         Paradigm operates from 13 locations, including 11 full-service banking
centers, its loan operations office and its corporate office. Paradigm owns six
of its banking centers, and leases the remaining five plus its loan operations
office and corporate office. The lease terms expire in 2003 through 2010, not
including renewal option periods that may be available. Paradigm's item
processing facility shares a building it owns with its Dayton Clayton Road
banking center, and its bank operations department shares a building it owns
with its Dayton Downtown banking center. Prosperity anticipates that Paradigm's
Medical Center, Dayton Clayton Road and Silver Ridge banking centers will be
closed upon completion of the merger or shortly thereafter.

         The following table sets forth the address, ownership status and
deposit balances for each of Paradigm's banking centers:

Employees

         At March 31, 2002, Paradigm had 146 employees, including 40 officers
and 29 part-time staff. Paradigm pays a significant portion of the cost of
health insurance for its full-time employees, and provides a significant
matching contribution with the 401(k) savings plan it offers them. Paradigm
considers its relations with its employees to be good. Paradigm is not party to
any collective bargaining agreements.

Legal Proceedings

         Paradigm and Paradigm Bank are from time to time parties to or
otherwise involved in legal proceedings arising in the normal course of
business. Management believes that neither Paradigm nor Paradigm Bank is a party
to, nor any of their property the subject of, any material pending or threatened
legal proceedings that, if determined adversely, would have a material adverse
effect on the consolidated financial condition, results of operations or cash
flows of Paradigm.

Supervision and Regulation

         The supervision and regulation of financial holding companies, banks
and affiliates is intended primarily for the protections of depositors,
borrowers, the deposit insurance funds of the Federal Deposit Insurance
Corporation and the banking system as a whole, not for the protection of
financial holding company shareholders or creditors. The regulatory authorities
have broad enforcement power over financial holding companies and banks,
including the power to impose substantial fines and other penalties for
violation of laws and regulations.

         The following descriptions summarize some of the laws and regulations
to which Paradigm and Paradigm Bank are subject. References herein to applicable
statutes and regulations are brief summaries, do not purport to be complete, and
are qualified in their entirety by reference to such statutes and regulations.
Paradigm believes that it is in compliance in all material respects with these
laws and regulations.

Paradigm Bancorporation, Inc.
-----------------------------

         Paradigm is a financial holding company registered under the
Gramm-Leach-Bliley Act, and a bank holding company registered under the Bank
Holding Company Act of 1956 as amended (BHCA). Accordingly, Paradigm is subject
to supervision, regulation and examination by the Federal Reserve. The
Gramm-Leach-Bliley Act, the BHCA and other federal laws subject financial and
bank holding companies to particular restrictions on the types of activities in
which they may engage, and to a range of supervisory requirements and
activities, including regulatory enforcement actions for violations of laws and
regulations.

         Regulatory Restrictions on Dividends; Source of Strength. It is the
policy of the Federal Reserve that financial holding companies should pay cash
dividends on common stock only out of income available over the past year and
only if prospective earnings retention is consistent with the organization's
expected future needs and financial condition. The policy provides that
financial holding companies should not maintain a level of cash dividends that
undermines the financial holding company's ability to serve as a source of
strength to its banking subsidiaries.

         Under the Federal Reserve policy, a financial holding company is
expected to act as a source of financial strength to each of its banking
subsidiaries and commit resources to their support. Such support may be required
at times when, absent this Federal Reserve policy, a holding company may not be
inclined to provide it. As discussed below, a financial holding company in
certain circumstances could be required to guarantee the capital plan of an
undercapitalized banking subsidiary.

         In the event of a financial holding company's bankruptcy under Chapter
11 of the U.S. Bankruptcy Code, the trustee will be deemed to have assumed and
is required to cure immediately any deficit under any commitment by the debtor
holding company to any of the federal banking agencies to maintain the capital
of an insured depository institution, and any claim for breach of such
obligation will generally have priority over most other unsecured claims.

         Scope of Permissible Activities. Under the BHCA, bank holding companies
generally may not acquire a direct or indirect interest in or control of more
than 5% of the voting shares of any company that is not a bank or bank holding
company or engage directly or indirectly in activities other than those of
banking, managing or controlling banks or furnishing services to its subsidiary
banks, except that it may engage in and may own shares of

                                       88



companies engaged in certain activities found by the Federal Reserve to be so
closely related to banking or managing and controlling banks as to be a proper
incident thereto. These activities include, among others, operating a mortgage,
finance, credit card, or factoring company; performing certain data processing
operations; providing investment and financial advice; acting as an insurance
agent for certain types of credit-related insurance; leasing personal property
on a full-payout, non-operating basis; and providing certain stock brokerage and
investment advisory services. In approving acquisitions or the addition of
activities, the Federal Reserve considers whether the acquisition or the
additional activities can reasonably be expected to produce benefits to the
public, such as greater convenience, increased competition, or gains in
efficiency, that outweigh such possible adverse effects as undue concentration
of resources, decreased or unfair competition, conflicts of interest or unsound
banking practices.

         However, the Gramm-Leach-Bliley Act effective in March 2000, eliminated
the barriers to affiliations among banks, securities firms, insurance companies
and other financial service providers. Paradigm elected and was approved to
become a financial holding company in April of 2000. The Gramm-Leach-Bliley Act
permits bank holding companies to become financial holding companies and thereby
affiliate with securities firms and insurance companies and engage in other
activities that are financial in nature. The Gramm-Leach-Bliley Act defines
"financial in nature" generally to include securities underwriting, dealing and
market making; sponsoring mutual funds and investment companies; insurance
underwriting and agency; merchant banking activities; and activities that the
Federal Reserve has determined to be closely related to banking. No regulatory
approval will be required for a financial holding company to acquire a company,
other than a bank or savings association, engaged in activities that are
financial in nature or incidental to activities that are financial in nature as
determined by the Federal Reserve.

         While the Federal Reserve will serve as the umbrella regulator for
financial holding companies and has the power to examine banking organizations
engaged in new activities, regulation and supervision of activities that are
financial in nature or determined to be incidental to such financial activities
will be handled along functional lines. Accordingly, activities of subsidiaries
of a financial holding company will be regulated by the agency or authorities
with the most experience regulating that activity as it is conducted in a
financial holding company.

         Safe and Sound Banking Practices. Financial holding companies are not
permitted to engage in unsafe and unsound banking practices. The Federal
Reserve's Regulation Y, for example, generally requires a holding company to
give the Federal Reserve prior notice of any redemption or repurchase of its own
equity securities, if the consideration to be paid, together with the
consideration paid for any repurchases or redemptions in the preceding year, is
equal to 10% or more of its consolidated net worth. The Federal Reserve may
oppose the transaction if it believes that the transaction would constitute an
unsafe or unsound practice or would violate any law or regulation. Depending
upon the circumstances, the Federal Reserve could take the position that paying
a dividend would constitute an unsafe or unsound banking practice.

         The Federal Reserve has broad authority to prohibit activities of
financial holding companies and their nonbanking subsidiaries which represent
unsafe and unsound banking practices or which constitute violations of laws or
regulations, and can assess civil money penalties for certain activities
conducted on a knowing and reckless basis, if those activities caused a
substantial loss to a depository institution. The penalties can be as high as $1
million for each day the activity continues.

         Anti-Tying Restrictions. Financial holding companies and their
affiliates are prohibited from tying the provision of certain services, such as
extensions of credit, to other nonbanking services offered by a holding company
or its affiliates.

         Capital Adequacy Requirements. The Federal Reserve has adopted a system
using risk-based capital guidelines to evaluate the capital adequacy of
financial holding companies. Under the guidelines, specific categories of assets
are assigned different risk weights, based generally on the perceived credit
risk of the asset. These risk weights are multiplied by corresponding asset
balances to determine a "risk-weighted" asset base. The guidelines require a
minimum total risk-based capital ratio of 8.0% (of which at least 4.0% is
required to consist of Tier 1 capital elements). Total capital is the sum of
Tier 1 and Tier 2 capital. At March 31, 2002, Paradigm's ratio of Tier 1 capital
to total risk-weighted assets was 10.37% and Paradigm's total capital to total
risk-weighted assets was 11.35%.

         In addition to the risk-based capital guidelines, the Federal Reserve
uses a leverage ratio as an additional tool to evaluate the capital adequacy of
financial holding companies. The leverage ratio is a company's Tier 1 capital
divided by its average total consolidated assets less goodwill and other
intangibles. Certain highly rated

                                       89



financial holding companies may maintain a minimum leverage ratio of 3.0%, but
other financial holding companies are required to maintain a leverage ratio of
at least 4.0%. At March 31, 2002, Paradigm's leverage ratio was 8.14%.

         The federal banking agencies' risk-based and leverage ratios are
minimum supervisory ratios generally applicable to banking organizations that
meet certain specified criteria. The federal bank regulatory agencies may set
capital requirements for a particular banking organization that are higher than
the minimum ratios when circumstances warrant. Federal Reserve guidelines also
provide that banking organizations experiencing internal growth or making
acquisitions will be expected to maintain strong capital positions substantially
above the minimum supervisory levels, without significant reliance on intangible
assets.

         Imposition of Liability for Undercapitalized Subsidiaries. Bank
regulators are required to take prompt corrective action to resolve problems
associated with insured depository institutions whose capital declines below
certain levels. In the event an institution becomes undercapitalized, it must
submit a capital restoration plan. The capital restoration plan will not be
accepted by the regulators unless each company having control of the
undercapitalized institution guarantees the subsidiary's compliance with the
capital restoration plan up to a certain specified amount. Any such guarantee
from a depository institution's holding company is entitled to a priority of
payment in bankruptcy.

         The aggregate liability of the holding company of an undercapitalized
bank is limited to the greater of 5% of the institution's assets at the time it
became undercapitalized or the amount necessary to cause the institution to be
adequately capitalized. The bank regulators have greater power in situations
where an institution becomes significantly or critically undercapitalized or
fails to submit a capital restoration plan. For example, a financial holding
company controlling such an institution can be required to obtain prior Federal
Reserve approval of proposed dividends, or might be required to consent to a
consolidation or to divest the troubled institution or other affiliates.

         Acquisitions by Financial Holding Companies. The BHCA requires every
bank holding company to obtain the prior approval of the Federal Reserve before
it may acquire all or substantially all of the assets of any bank, or ownership
or control of any voting shares of any bank, if after such acquisition it would
own or control, directly or indirectly, more than 5% of the voting shares of
such bank. In approving bank acquisitions by financial holding companies, the
Federal Reserve is required to consider the financial and managerial resources
and future prospects of the financial holding company and the banks concerned,
the convenience and needs of the communities to be served, and various
competitive factors.

         Control Acquisitions. The Change in Bank Control Act prohibits a person
or group of persons from acquiring control of a financial holding company unless
the Federal Reserve has been notified and has not objected to the transaction.
Under a rebuttable presumption established by the Federal Reserve, the
acquisition of 10% or more of a class of voting stock of a financial holding
company with a class of securities registered under Section 12 of the Exchange
Act would, under the circumstances set forth in the presumption, constitute
acquisition of control of the holding company.

         In addition, an entity is required to obtain the approval of the
Federal Reserve under the BHCA before acquiring 25% (5% in the case of an
acquiror that is a financial holding company) or more of Paradigm's outstanding
common stock, or otherwise obtaining control or a controlling influence over
Paradigm.

Paradigm Bank Texas
-------------------

         Paradigm Bank is a Texas-chartered banking association, the deposits of
which are insured by the Bank Insurance Fund (BIF) of the FDIC. Paradigm Bank is
not a member of the Federal Reserve System; therefore, it is subject to
supervision and regulation by the FDIC and the Texas Banking Department. Such
supervision and regulation subjects Paradigm Bank to special restrictions,
requirements, potential enforcement actions and periodic examination by the FDIC
and the Texas Banking Department. Because the Federal Reserve regulates
Paradigm, as the financial holding company parent of Paradigm Bank, the Federal
Reserve also has supervisory authority that directly affects Paradigm Bank.

         Equivalence to National Bank Powers. The Texas Constitution, as amended
in 1986, provides that a Texas-chartered bank has the same rights and privileges
that are or may be granted to national banks domiciled in Texas. To the extent
that the Texas laws and regulations may have allowed state-chartered banks to
engage in a broader range of activities than national banks, the Federal Deposit
Insurance Corporation Improvement Act of 1991

                                       90



(FDICIA) has operated to limit this authority. FDICIA provides that no state
bank or subsidiary thereof may engage as principal in any activity not permitted
for national banks, unless the institution complies with applicable capital
requirements and the FDIC determines that the activity poses no significant risk
to the insurance fund. In general, statutory restrictions on the activities of
banks are aimed at protecting the safety and soundness of depository
institutions.

         Branching. Texas law provides that a Texas-chartered bank can establish
a branch anywhere in Texas provided that the branch is approved by the Texas
Department of Banking and the appropriate federal agency, which in Paradigm's
case is the FDIC, which considers a number of factors, including financial
history, capital adequacy, earnings prospects, character of management, needs of
community and consistency with corporate powers.

         Restrictions on Transactions with Affiliates and Insiders. Transactions
between banks and their nonbanking affiliates, including holding companies and
any nonbanking subsidiaries, are subject to Section 23A of the Federal Reserve
Act. In general, Section 23A imposes limits on the amount of such transactions,
and also requires certain levels of collateral for loans to affiliated parties.
It also limits the amount of advances to third parties that are collateralized
by our securities or obligations or the securities or obligations of any of our
nonbanking subsidiaries.

         Affiliated transactions are also subject to Section 23B of the Federal
Reserve Act which generally requires that certain transactions between the banks
and their affiliates be on terms substantially the same, or at least as
favorable to the banks, as those prevailing at the time for comparable
transactions with or involving other nonaffiliated persons.

         The restrictions on loans to directors, executive officers, principal
shareholders and their related interests (collectively referred to herein as
insiders) contained in the Federal Reserve Act and Federal Reserve Regulation O
apply to all insured institutions and their subsidiaries and holding companies.
These restrictions include limits on loans to one borrower and conditions that
must be met before such a loan can be made. There is also an aggregate
limitation on all loans to insiders and their related interests. These loans
cannot exceed the institution's total unimpaired capital and surplus, and the
FDIC may determine that a lesser amount is appropriate. Insiders are subject to
enforcement actions for knowingly accepting loans in violation of applicable
restrictions.

         Restrictions on Distribution of Subsidiary Bank Dividends and Assets.
Dividends paid by Paradigm Bank have provided a substantial part of Paradigm's
operating funds and for the foreseeable future it is anticipated that dividends
paid by Paradigm Bank to Paradigm will continue to be Paradigm's principal
source of operating funds. Capital adequacy requirements serve to limit the
amount of dividends that may be paid by Paradigm Bank. Under federal laws,
Paradigm Bank cannot pay a dividend if, after paying the dividend, Paradigm Bank
will be undercapitalized. The FDIC may declare a dividend payment to be unsafe
and unsound even though Paradigm Bank would continue to meet its capital
requirement after the dividend.

         Because Paradigm is a legal entity separate and distinct from its
subsidiaries, its right to participate in the distribution of assets of any
subsidiary upon the subsidiary's liquidation or reorganization will be subject
to the prior claims of the subsidiary's creditors. In the event of a liquidation
or other resolution of an insured depository institution, the claims of
depositors and other general or subordinated creditors are entitled to a
priority of payment over the claims of holders of any obligation of the
institution to its shareholders, including any depository institution holding
company (such as Paradigm) or any shareholder or creditor thereof.

         Examinations. The FDIC periodically examines and evaluates insured
banks. Based on such an evaluation, the FDIC may revalue the assets of the
institution and require that it establish specific reserves to compensate for
the difference between the FDIC-determined value and the book value of such
assets. The Texas Banking Department also conducts examinations of state banks
but may accept the results of a federal examination in lieu of conducting an
independent examination.

         Capital Adequacy Requirements. The FDIC has adopted regulations
establishing minimum requirements for the capital adequacy of insured
institutions. The FDIC may establish higher minimum requirements if, for
example, a bank has previously received special attention or has a high
susceptibility to interest rate risk.

         The FDIC's risk-based capital guidelines generally require state banks
to have a minimum ratio of Tier 1 capital to total-risk weighted asset of 4.0%
and a ratio of total capital to total risk-weighted assets of 8.0%. The capital
categories have the same definitions for banks as for holding companies. At
March 31, 2002, Paradigm

                                       91



Bank's ratio of Tier 1 capital to total risk-weighted assets was 10.05% and its
ratio of total capital to total risk-weighted assets was 11.03%.

         The FDIC's leverage guidelines require state banks to maintain Tier 1
capital of no less than 5.0% of average total assets, except in the case of
certain highly rated banks for which the requirement is 3.0% of average total
assets. The Texas Banking Department has issued a policy that generally requires
state chartered banks to maintain a leverage ratio (defined in accordance with
federal capital guidelines) of 6.0%. At March 31, 2002, Paradigm Bank's ratio of
Tier 1 capital to average total assets (leverage ratio) was 7.96%.

         Corrective Measures for Capital Deficiencies. The federal banking
regulators are required to take prompt corrective action with respect to
capital-deficient institutions. Agency regulations define, for each capital
category, the levels at which institutions are "well capitalized," "adequately
capitalized," "under capitalized," "significantly under capitalized," and
"critically under capitalized." A "well capitalized" bank has a total risk-based
capital ratio of 10.0% or higher; a Tier 1 risk-based capital ratio of 6.0% or
higher; a leverage ratio of 5.0% or higher; and is not subject to any written
agreement, order or directive requiring it to maintain a specific capital level
for any capital measure. An "adequately capitalized" bank has a total risk-based
capital ratio of 8.0% or higher; a Tier 1 risk-based capital ratio of 4.0% or
higher; a leverage ratio of 4.0% or higher (3.0% or higher if the bank was rated
a composite 1 in its most recent examination report and is not experiencing
significant growth); and does not meet the criteria for being a "well
capitalized bank". A bank is "under capitalized" if it fails to meet any one of
the ratios required to be adequately capitalized. Paradigm Bank is classified as
"well capitalized" for purpose of the FDIC's prompt corrective action
regulations.

         In addition to requiring undercapitalized institutions to submit a
capital restoration plan, agency regulations contain broad restrictions on
certain activities of undercapitalized institutions including asset growth,
acquisitions, branch establishment and expansion into new lines of business.
With certain exceptions, an insured depository institution is prohibited from
making capital distributions, including dividends, and is prohibited from paying
management fees to control persons if the institution would be undercapitalized
after any such payment.

         As an institution's capital decreases, the FDIC's enforcement powers
become more severe. A significantly undercapitalized institution is subject to
mandated capital raising activities, restrictions on interest rates paid and
transactions with affiliates, removal of management and other restrictions. The
FDIC has only very limited discretion in dealing with a critically
undercapitalized institution and is virtually required to appoint a receiver or
conservator.

         Banks with risk-based capital and leverage ratios below the required
minimums may also be subject to certain administrative actions, including the
termination of deposit insurance upon notice and hearing, or a temporary
suspension of insurance without a hearing in the event the institution has no
tangible capital.

         Deposit Insurance Assessments. Paradigm Bank must pay assessments to
the FDIC for federal deposit insurance protection. The FDIC has adopted a
risk-based assessment system as required by FDICIA. Under this system,
FDIC-insured depository institutions pay insurance premiums at rates based on
their risk classification. Institutions assigned to higher risk classifications
(that is, institutions that pose a greater risk of loss to their respective
deposit insurance funds) pay assessments at higher rates than institutions that
pose a lower risk. An institution's risk classification is assigned based on its
capital levels and the level of supervisory concern the institution poses to the
regulators. In addition, the FDIC can impose special assessments in certain
instances. The current range of BIF assessments is between zero and 0.27% of
deposits.

         The FDIC established a process for raising or lowering all rates for
insured institutions semi-annually if conditions warrant a change. Under this
system, the FDIC has the flexibility to adjust the assessment rate schedule
twice a year without seeking prior public comment, but only within a range of
five cents per $100 above or below the premium schedule adopted. The FDIC can
make changes in the rate schedule outside the five-cent range above or below the
current schedule only after a full rulemaking with opportunity for public
comment.

         In addition to BIF assessments, banks insured under the BIF are
required to pay a portion of the interest due on bonds that were issued by the
Financing Corporation (FICO) to help shore up the ailing Federal Savings and
Loan Insurance Corporation in 1987. The BIF-rate was required to equal one-fifth
of the Savings Association Insurance Fund (SAIF) rate through year-end 1999, or
until the insurance funds merged, whichever occurred first. Thereafter, BIF and
SAIF payers will be assessed pro rata for the FICO bond obligations. With regard
to the

                                       92



assessment for the FICO obligation, for the second quarter 2002, both the
BIF and SAIF rates were 0.0176% of deposits.

         Enforcement Powers. The FDIC and the other federal banking agencies
have broad enforcement powers, including the power to terminate deposit
insurance, impose substantial fines and other civil and criminal penalties and
appoint a conservator or receiver. Failure to comply with applicable laws,
regulations and supervisory agreements could subject Paradigm or Paradigm Bank,
as well as officers, directors and other institution-affiliated parties of these
organizations, to administrative sanctions and potentially substantial civil
money penalties.

         The appropriate federal banking agency may appoint the FDIC as
conservator or receiver for a banking institution (or the FDIC may appoint
itself, under certain circumstances) if any one or more of a number of
circumstances exist, including, without limitation, the banking institution is
undercapitalized and has no reasonable prospect of becoming adequately
capitalized; fails to become adequately capitalized when required to do so:
fails to submit a timely and acceptable capital restoration plan; or materially
fails to implement an accepted capital restoration plan. The Texas Banking
Department also has broad enforcement powers over Paradigm Bank, including the
power to impose orders, remove officers and directors, impose fines and appoint
supervisors and conservators.

         Brokered Deposit Restrictions. Institutions that are only adequately
capitalized (as defined for purposes of the prompt corrective action rules
described above) cannot accept, renew or roll over brokered deposits except with
a waiver from the FDIC, and are subject to restrictions on the interest rates
that can be paid on such deposits. Undercapitalized institutions may not accept,
renew, or roll over brokered deposits.

         Cross-Guarantee Provisions. The Financial Institutions Reform, Recovery
and Enforcement Act of 1989 (FIRREA) contains a cross-guarantee provision that
generally makes commonly controlled insured depository institutions liable to
the FDIC for any losses incurred in connection with the failure of a commonly
controlled depository institution.

         Community Reinvestment Act. The Community Reinvestment Act of 1977
(CRA) and the regulations issued thereunder are intended to encourage banks to
help meet the credit needs of their service area, including low and moderate
income neighborhoods, consistent with the safe and sound bank operations. These
regulations also provide for regulatory assessment of a bank's record in meeting
the needs of its service area when considering applications to establish
branches, merger applications and applications to acquire the assets and assume
the liabilities of another bank. FIRREA requires federal banking agencies to
make public a rating of a bank's performance under the CRA. In the case of a
financial holding company, the CRA performance record of the banks involved in
the transaction are reviewed in connection with the filing of an application to
acquire ownership or control of shares or assets of a bank or to merge with any
other financial holding company. An unsatisfactory record can substantially
delay or block the transaction.

         Consumer Laws and Regulations. In addition to the laws and regulations
discussed herein, Paradigm Bank is subject to certain consumer laws and
regulations that are designed to protect consumers in transactions with banks.
While the list set forth herein is not exhaustive, these laws and regulations
include the Truth in Lending Act, the Truth in Savings Act, the Electronic Funds
Transfer Act, The Expedited Funds Availability Act, The Equal Credit Opportunity
Act, and the Fair Housing Act, among others. These laws and regulations mandate
certain disclosure requirements and regulate the manner in which financial
institutions must deal with customers when taking deposits or making loans to
such customers. Paradigm Bank must comply with the applicable provisions of
these consumer protection laws and regulations as part of its ongoing customer
relations.

         The USA Patriot Act of 2001. The USA Patriot Act is intended to
strengthen U.S. law enforcement's and the intelligence community's ability to
work cohesively to combat terrorism on a variety of fronts. The potential impact
of the USA Patriot Act on financial institutions of all kinds is significant and
wide ranging. The USA Patriot Act requires financial institutions to prohibit
correspondent accounts with foreign shell banks, establish an anti-money
laundering program that includes employee training and an independent audit,
follow minimum standards for identifying customers and maintaining records of
the identification information and make regular comparisons of customers against
agency lists of suspected terrorists, their organizations and money launderers.

         Privacy. In addition to expanding the activities in which banks and
bank holding companies may engage, the Gramm-Leach-Bliley Act also imposed new
requirements on financial institutions with respect to customer privacy. The
Gramm-Leach-Bliley Act generally prohibits disclosure of customer information to
non-affiliated third

                                       93



parties unless the customer has been given the opportunity to object and has not
objected to such disclosure. Financial institutions are further required to
disclose their privacy policies to customers annually. Financial institutions,
however, will be required to comply with state law if it is more protective of
customer privacy than the Gramm-Leach-Bliley Act.

Instability and Regulatory Structure

         Various legislation, including proposals to overhaul the bank
regulatory system, expand the powers of banking institutions and financial
holding companies and limit the investments that a depository institution may
make with insured funds, is from time to time introduced in Congress. Such
legislation may change banking statutes and the environment in which Paradigm
and its banking subsidiaries operate in substantial and unpredictable ways.
Paradigm cannot determine the ultimate effect that potential legislation, if
enacted, or implementing regulations with respect thereto, would have upon its
financial condition or results of operations or that of its subsidiaries.

Expanding Enforcement Authority

         One of the major additional burdens imposed on the banking industry by
FDICIA is the increased ability of banking regulators to monitor the activities
of banks and their holding companies. In addition, the Federal Reserve and the
FDIC are possessed of extensive authority to police unsafe and unsound practices
and violations of applicable laws and regulations by depository institutions and
their holding companies. For example, the FDIC may terminate the deposit
insurance of any institution that it determines has engaged in unsafe or unsound
practices. The agencies can also assess civil money penalties, issue cease and
desist or removal orders, seek injunctions, and publicly disclose such actions.
FDICIA, FIRREA and other laws have expanded the agencies' authority in recent
years, and the agencies have not yet fully tested the limits of their powers.

Monetary Policy

         The policies of regulatory authorities, including the monetary policy
of the Federal Reserve, have a significant effect on the operating results of
financial holding companies and their subsidiaries. Among the means available to
the Federal Reserve to affect the money supply are open market operations in
U.S. government securities, changes in the discount rate on member bank
borrowings, and changes in reserve requirements against member bank deposits.
These means are used in varying combinations to influence overall growth and
distribution of bank loans, investments and deposits, and their use may affect
interest rates charged on loans and paid for deposits.

         Federal Reserve monetary policies have materially affected the
operating results of commercial banks in the past and are expected to continue
to do so in the future. The nature of future monetary policies and the effect of
such policies on the business and earnings of Paradigm and its subsidiaries
cannot be predicted.

         Until the merger is completed or the merger agreement is terminated,
Paradigm is prohibited from declaring or paying any dividends on its capital
stock, other than its regular periodic cash dividends per share. However, the
parties have agreed that Paradigm may pay a cash dividend of $0.05 per share in
July 2002 and, if the merger is not completed prior to the record date for
Prosperity's third quarter dividend, Paradigm may pay a cash dividend in an
amount equal to the quarterly dividend Paradigm shareholders would receive as
shareholders of Prosperity. The declaration and payment of such dividends will
be at the discretion of the board of directors of Paradigm and will depend upon
future earnings of Paradigm, its general financial condition, the success of its
business activities, its capital requirements and general business conditions.

         The principal source of cash revenues to Prosperity is dividends paid
by Prosperity Bank with respect to its capital stock. There are certain
restrictions on the payment of such dividends imposed by federal and state
banking laws, regulations and authorities. As of June 30, 2002, an aggregate of
approximately $41.7 million was available for payment of dividends by Prosperity
Bank to Prosperity under applicable restrictions, without regulatory approval.
Regulatory authorities could impose administratively stricter limitations on the
ability of Prosperity Bank to pay dividends to Prosperity if such limits were
deemed appropriate to preserve certain capital adequacy requirements.

         As of May 31, 2002, an aggregate of approximately $3.5 million was
available for payment of dividends by Paradigm Bank to Paradigm under applicable
restrictions, without regulatory approval. If Prosperity and Paradigm do not
merge, the board of directors of Paradigm intends to continue to consider the
payment of quarterly dividends on the outstanding shares of Paradigm common
stock.

                     DESCRIPTION OF PROSPERITY CAPITAL STOCK

General

         Prosperity has authorized two classes of stock: (1) 50,000,000
authorized shares of Prosperity common stock, par value $1.00 per share,
16,279,370 shares of which are outstanding as of July 18, 2002; and (2)
20,000,000 authorized shares of preferred stock, par value $1.00 per share, none
of which have been issued. The following summary is qualified in its entirety by
reference to the articles of incorporation and bylaws of Prosperity.

Prosperity Common Stock

         The holders of Prosperity common stock are entitled to one vote for
each share of Prosperity common stock owned. Except as expressly provided by law
and except for any voting rights that may be conferred on any shares of
preferred stock issued by the Prosperity board, all voting power is in
Prosperity common stock. Holders of Prosperity common stock may not cumulate
their votes for the election of directors. Holders of Prosperity common stock do
not have preemptive rights to acquire any additional, unissued or treasury
shares of Prosperity, or securities of Prosperity convertible into or carrying a
right to subscribe to or acquire shares of Prosperity.

                                       98



         Holders of Prosperity common stock will be entitled to receive
dividends out of funds legally available therefor, if and when properly declared
by the Prosperity board. However, the Prosperity board may not declare or pay
cash dividends on Prosperity common stock, and no Prosperity common stock may be
purchased by Prosperity, unless full dividends on outstanding preferred stock
for all past dividend periods and for the current dividend period, if any, have
been declared and paid.

         On liquidation of Prosperity, the holders of Prosperity common stock
are entitled to share pro rata in any distribution of the assets of Prosperity,
after the holders of shares of preferred stock have received the liquidation
preference of their shares plus any cumulated but unpaid dividends, whether or
not earned or declared, if any, and after all other indebtedness of Prosperity
has been retired.

Preferred Stock

         Prosperity is authorized to issue 20,000,000 shares of preferred stock.
The preferred stock is available for issuance from time to time for various
purposes as determined by the Prosperity board, including making future
acquisitions, raising additional equity capital and financing. Subject to
certain limits set by the Prosperity articles, the preferred stock may be issued
on such terms and conditions, and at such times and in such situations, as the
Prosperity board in its sole discretion determines to be appropriate, without
any further approval or action by the shareholders, unless otherwise required by
laws, rules, regulations or agreements applicable to Prosperity.

         Moreover, except as otherwise limited by the Prosperity articles or
applicable laws, rules or regulations, the Prosperity board has the sole
authority to determine the relative rights and preferences of the preferred
stock and any series thereof without shareholder approval. The Prosperity
articles require all shares of preferred stock to be identical, except as to the
following characteristics, which may vary between different series of preferred
stock:

         .    dividend rate, preference of dividend with respect to any other
              class or series of stock, and cumulativity, non-cumulativity or
              partial cumulativity of dividends;

         .    redemption price and terms, including, to the extent permitted by
              law, the manner in which shares are to be chosen for redemption
              if less than all the shares of a series are to be redeemed;

         .    sinking fund provisions, if any, for the redemption or purchase
              of shares;

         .    the amount payable upon shares in the event of voluntary or
              involuntary liquidation;

         .    the terms and conditions on which shares may be converted, if the
              shares of any series are issued with the privilege of conversion;
              and

         .    voting rights.

         The Prosperity board does not intend to seek shareholder approval prior
to any issuance of preferred stock or any series thereof, unless otherwise
required by law or the rules of any applicable securities exchange. Under Texas
law, shareholder approval prior to the issuance of shares of Prosperity common
stock is required in connection with certain mergers. Frequently, opportunities
arise that require prompt action, such as the possible acquisition of a property
or business or the private sale of securities, and it is the belief of the
Prosperity board that the delay necessary for shareholder approval of a specific
issuance could be to the detriment of Prosperity and its shareholders.

         The preferred stock could be deemed to have an anti-takeover effect in
that, if a hostile takeover situation should arise, shares of preferred stock
could be issued to purchasers sympathetic with Prosperity's management or others
in such a way as to render more difficult or to discourage a merger, tender
offer, proxy contest, the assumption of control by a holder of a large block of
Prosperity's securities or the removal of incumbent management.

         The effects of the issuance of the preferred stock on the holders of
Prosperity common stock could include:

         .    reduction of the amount otherwise available for payments of
              dividends on Prosperity common stock if dividends are payable on
              the series of preferred stock;

                                       99



         .    restrictions on dividends on Prosperity common stock if dividends
              on the series of preferred stock are in arrears;

         .    dilution of the voting power of Prosperity common stock if the
              series of preferred stock has voting rights, including a possible
              "veto" power if the series of preferred stock has class voting
              rights;

         .    dilution of the equity interest of holders of Prosperity common
              stock if the series of preferred stock is convertible, and is
              converted, into Prosperity common stock; and

         .    restrictions on the rights of holders of Prosperity common stock
              to share in Prosperity's assets upon liquidation until
              satisfaction of any liquidation preference granted to the holders
              of the series of preferred stock.

NOTE A    BASIS OF PRESENTATION

          The accompanying unaudited interim consolidated financial statements
          have been prepared in accordance with generally accepted accounting
          principles for interim financial information and with the rules and
          regulations of the Securities and Exchange Commission. Accordingly,
          they do not include all of the information and footnotes required by
          generally accepted accounting principles for complete financial
          statements. In the opinion of management, all adjustments (consisting
          of normal recurring items) considered necessary for a fair
          presentation have been included. Operating results for the three-month
          period ended March 31, 2002 are not necessarily indicative of the
          results that may be expected for the entire year or any interim
          period. For further information, refer to the consolidated financial
          statements and notes thereto included in the annual report on Form
          10-KSB of Paradigm Bancorporation, Inc. and Subsidiaries for the year
          ended December 31, 2001. Certain prior period amounts have been
          reclassified to conform to current period presentation.

NOTE B    EARNINGS PER COMMON SHARE

          Earnings per common share (EPS) were computed based on the following:

          Because share prices have been at or below option strike prices, there
          were no material dilutive securities as of March 31, 2002 and 2001.

NOTE C    SUBSEQUENT EVENT - PROPERTY SALE

          In June 2002, Paradigm received gross proceeds of $1,069,000 from the
          State of Texas and Harris County as compensation for taking part of
          the banking center land and parking lot at 2828 FM 1960 East. In June
          2002, Paradigm recognized a gain on sale of that property of $427,000,
          net of the property cost basis, attorney's fees and other transaction
          costs.

NOTE D    EFFECT OF THE MERGER ON COMPENSATION EXPENSE

          As a result of the proposed merger between Paradigm Bancorporation,
          Inc. and Prosperity Bancshares, Inc., certain senior officers of
          Paradigm will receive change in control payments in the aggregate
          amount of $653,000. The change in control payments will be recorded as
          compensation expense by Paradigm immediately prior to the closing of
          the merger.

--------------------------------------------------------------------------------

NOTE D    EFFECT OF THE MERGER ON COMPENSATION EXPENSE (continued)

          Stock options issued pursuant to the Paradigm Bancorporation, Inc.
          1999 Stock Incentive Plan that are outstanding immediately prior to
          completion of the merger will vest and will automatically be converted
          into an option to purchase Prosperity common stock and will continue
          to be governed by the terms of the original plan under which they were
          issued. Management anticipates that 32,340 stock options will be
          outstanding at the closing date of the merger.

          Stock Appreciation Rights (SAR) granted pursuant to the Paradigm 1998
          Stock Appreciation Rights Plan that are outstanding immediately prior
          to completion of the merger will be cancelled and automatically
          convert into the right of each holder to receive for each SAR an
          amount of cash determined by certain calculations related to the price
          of Prosperity common stock at the agreed upon exchange rate.
          Managements' estimate of expense to be recorded by Paradigm
          immediately prior to the closing of the merger, based upon the market
          price of Prosperity common stock at May 30, 2002, is $640,000.

statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards

used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a

--------------------------------------------------------------------------------

NOTE A     ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING
           POLICIES

           Principles of Consolidation - The accompanying consolidated financial
           ---------------------------
           statements include the accounts of Paradigm Bancorporation, Inc.
           (Paradigm) and its wholly owned subsidiaries Paradigm Capital Trust I
           (Trust I), Paradigm Capital Trust II (Trust II), Paradigm Delaware
           Bancorporation, Inc. (Delaware), and Paradigm Bank Texas (Paradigm
           Bank or Bank). Paradigm Bank was formed as a result of the merger of
           Woodcreek Bank (Woodcreek) and Dayton State Bank (Dayton) in 2000.
           All significant intercompany balances and activity have been
           eliminated.

           Nature of Operations - Paradigm through its subsidiary, Paradigm
           --------------------
           Bank, provides a broad line of banking products and services for
           small to medium-sized businesses and for individuals through its
           community banking offices in Houston, Galveston, Dayton, Winnie and
           Mt. Belvieu, Texas.

           Purchase of First National Bank of Dayton (First National) - In 1997,
           ----------------------------------------------------------
           Woodcreek acquired the First National Bank of Dayton for about
           $2,508,000. This was accounted for as a purchase and accordingly, the
           operating results of First National are included in the results of
           operations of Paradigm Bank from the date of acquisition. The excess
           of the consideration paid over the fair value of the net assets
           acquired was recorded as goodwill of about $794,000. As explained in
           Note I, about $331,000 of goodwill from the purchase of First
           National was reclassified to deferred tax assets in 2000. The
           remaining goodwill of about $463,000 from this purchase is being
           amortized ratably over 15 years. A change in accounting treatment for
           purchased goodwill will be adopted by Paradigm January 1, 2002 as
           explained in Note A under Goodwill and Other Intangible Assets.

           Purchase of Dayton State Bank - Effective December 1, 1999, Paradigm
           -----------------------------
           acquired all of the outstanding common stock of Dayton for
           $17,257,912. This acquisition was accounted for as a purchase and
           accordingly, the operating results of Dayton are included in
           Paradigm's results of operations from the date of acquisition. The
           excess of the consideration paid over the fair value of the net
           assets acquired was recorded as goodwill of about $3,298,000 and is
           being amortized ratably over 20 years. Please refer to Goodwill and
           Other Intangible Assets as included in Note A for a change in this
           accounting method effective January 1, 2002. In December 2000, Dayton
           was merged with Woodcreek to form Paradigm Bank.

           To finance the Dayton purchase, Paradigm: (1) sold 875,000 of its
           common shares for $7,000,000; (2) formed a wholly-owned subsidiary,
           Paradigm Capital Trust I, which sold 512,500 shares of trust
           preferred securities for $5,000,000; and (3) upon closing the
           transaction with the Dayton shareholders, received a $5,600,000
           dividend from Dayton which was then paid to Dayton shareholders as
           part of the purchase price.

                                      Notes To Consolidated Financial Statements
                                                      December 31, 2001 and 2000
--------------------------------------------------------------------------------

NOTE A     ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING
           POLICIES (continued)

           In 2000, Paradigm Capital Trust II (Trust II), a statutory business
           trust was formed under the laws of the State of Delaware. In February
           2001, Trust II then sold 600,000 Floating Rate Cumulative Trust
           Preferred Securities for $6,000,000 cash. These securities are
           registered with the Securities and Exchange Commission and are traded
           in the over the counter market. The trust preferred securities of
           Trust II have a $10 liquidation preference, provide for quarterly
           interest payments at the three month LIBOR rate plus 4.5%, and must
           be redeemed no later than February 14, 2031. The trust preferred
           securities may be redeemed on or after February 14, 2006 if certain
           conditions (including approval from the Federal Reserve, if then
           required) are met. Proceeds of this sale were used primarily to pay
           off the existing outstanding trust preferred securities of Trust I
           for $5,201,814, which included accrued interest of about $77,000.

           At December 31, 2001 and 2000, certain of the selling Dayton
           shareholders had not yet tendered their Dayton shares to Paradigm.
           Consequently, about $222,000 and $646,000 of the purchase cost was
           included in due to former shareholders in the accompanying
           consolidated statements of condition for December 31, 2001 and 2000,
           respectively. This will be paid to the selling Dayton shareholders
           upon receipt by Paradigm of the certificates representing the shares
           of Dayton common stock held by the former Dayton shareholders.

           Pursuant to the terms of the purchase agreement, Paradigm is holding
           approximately $468,000 in escrow for the benefit of the selling
           Dayton shareholders. This amount is included in due to shareholders
           on the consolidated statements of condition. Under this agreement,
           some or all of this escrow will be paid to the former Dayton
           shareholders after specified loans have been paid off or deemed to be
           paying as agreed without risk of loss to the Bank. At the expiration
           of the escrow agreement, amounts held in escrow specifically assigned
           to loans that have not paid off and continue to present a risk of
           loss to the Bank will become the property of Paradigm. The
           dispensation of the funds held in escrow is described in Note U.

           Summary of Significant Accounting and Reporting Policies - The
           --------------------------------------------------------
           accounting and reporting policies of Paradigm conform to generally
           accepted accounting principles in the United States (GAAP) and to the
           prevailing practices within the banking industry. A summary of
           significant accounting policies is as follows:

           Account Classification - Certain prior year amounts have been
           ----------------------
           reclassified to conform to the current year presentation.

           Use of Estimates - The preparation of financial statements in
           ----------------
           conformity with GAAP requires management to make estimates and
           assumptions that affect the reported amounts of assets and
           liabilities and disclosures of contingent assets and liabilities at
           the date of the financial statements and the reported amounts of
           revenues and expenses during the reporting period. Actual results
           could differ from these estimates.

                                                      December 31, 2001 and 2000
--------------------------------------------------------------------------------

NOTE A     ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING
           POLICIES (continued)

           The determination of the adequacy of the allowance for credit losses
           is based on estimates that are susceptible to significant changes in
           the economic environment and market conditions. The Bank's loans are
           generally secured by specific items of collateral including real
           property, consumer assets, and business assets. Although the Bank has
           a diversified loan portfolio, a substantial portion of the debtors'
           ability to honor their contracts is dependent on local economic
           conditions. In connection with the determination of the estimated
           exposure and risk of loss on loans, management obtains independent
           appraisals for significant collateral.

           While management uses available information to recognize losses on
           loans, further reductions in the carrying amounts of loans may be
           necessary based on changes in local economic conditions. In addition,
           regulatory agencies, as an integral part of their examination
           process, periodically review the estimated losses on loans. Such
           agencies may require the Bank to recognize additional losses based on
           their judgments about information available to them at the time of
           their examination. Because of these factors, it is reasonably
           possible that the estimated losses on loans may change materially in
           the near term. However, the amount of the change that is reasonably
           possible cannot be estimated.

           Cash and Due From Banks - The Bank is required to maintain reserves
           -----------------------
           for the purpose of facilitating the implementation of monetary
           policy. These reserves may be maintained in the form of balances at
           the Federal Reserve Bank, a correspondent bank, or by vault cash.
           Reserve requirements were $5,302,000 and $2,485,000 at December 31,
           2001 and 2000, respectively. Accordingly, cash and due from banks
           balances were restricted to that extent. The Bank's cash in financial
           institutions exceeded the federally insured deposits limit by
           approximately $2,460,000 at December 31, 2001. In managing this
           credit risk, the Bank periodically evaluates the stability of the
           financial institutions in which it maintains cash balances.

           Investment Securities - Available-for-sale investment securities are
           ---------------------
           carried at fair value. Unrealized gains and losses are excluded from
           earnings and reported as a separate component of stockholders' equity
           until realized. Securities within the available-for-sale portfolio
           may be used as part of the Bank's assets/liability strategy and may
           be sold in response to changes in interest rate risk, prepayment risk
           or other similar economic factors.

           Held-to-maturity investment securities are carried at cost, adjusted
           for the amortization of premiums and the accretion of discounts.
           Management has the positive intent and the Bank has the ability to
           hold these assets as long-term investments until their estimated
           maturities. Under certain circumstances (including the significant
           deterioration of the issuer's creditworthiness or a significant
           change in tax-exempt status or statutory or regulatory requirements),
           securities held to maturity may be sold or transferred to another
           portfolio.

           Premiums and discounts are amortized and accreted to operations using
           the level yield method of accounting, adjusted for prepayments as
           applicable. The specific identification method of accounting is used
           to compute gains or losses on the sale of these assets.

NOTE A     ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING
           POLICIES (continued)

           Loans - Loans are stated at the principal amount outstanding, net of
           -----
           unearned discounts. Unearned discounts relate principally to consumer
           installment loans and are amortized using a method that approximates
           the interest method. For other loans, such income is recognized using
           the simple interest method.

           Nonperforming Loans and Past-Due Loans - Included in the
           --------------------------------------
           nonperforming and past-due loans category are loans which have been
           categorized by management as nonaccrual because collection of
           interest is doubtful and loans which have been restructured to
           provide a reduction in the interest rate or a deferral of interest or
           principal payments.

           When the payment of principal or interest on a loan is delinquent for
           90 days, or earlier in some cases, the loan is placed on nonaccrual
           status, unless the loan is in the process of collection and the
           underlying collateral fully supports the carrying value of the loan.
           If the decision is made to continue accruing interest on the loan,
           periodic reviews are made to confirm the accruing status of the loan.
           When a loan is placed on nonaccrual status, interest accrued during
           the current year prior to the judgment of uncollectibility is charged
           to operations. Interest accrued during prior periods is charged to
           the allowance for credit losses. Generally, any payments received on
           nonaccrual loans are applied first to outstanding loan amounts and
           next to the recovery of charged-off loan amounts. Any excess is
           treated as recovery of lost interest.

           Restructured loans are those loans on which concessions in terms have
           been granted because of a borrower's financial difficulty. Interest
           is generally accrued on such loans in accordance with the new terms.

           Allowance for Credit Losses - The allowance for credit losses is a
           ---------------------------
           valuation allowance available for losses incurred on loans. All
           losses are charged to the allowance when the loss actually occurs or
           when a determination is made that a loss is likely to occur.
           Recoveries are credited to the allowance at the time of recovery.

           Throughout the year, management estimates the likely level of losses
           to determine whether the allowance for credit losses is adequate to
           absorb losses inherent in the existing portfolio. Based on these
           estimates, an amount is charged to the provision for credit losses
           and credited to the allowance for credit losses in order to adjust
           the allowance to a level determined to be adequate to absorb such
           inherent losses.

           Management's judgment as to the level of losses on existing loans
           involves the consideration of current and anticipated economic
           conditions and their potential effects on specific borrowers; an
           evaluation of the existing relationships among loans, potential
           credit losses and the present level of the allowance; results of
           examinations of the loan portfolio by regulatory agencies; and
           management's internal review of the loan portfolio. In determining
           the collectibility of certain loans, management also considers the
           fair value of any underlying collateral. The amounts ultimately
           realized may differ from the carrying value of these assets because
           of economic, operating or other conditions beyond the Bank's control.

                                                      December 31, 2001 and 2000
--------------------------------------------------------------------------------

NOTE A    ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING
          POLICIES (continued)

          Estimates of credit losses involve an exercise of judgment. While it
          is reasonably possible that in the short-term the Bank may sustain
          losses which are substantial relative to the allowance for credit
          losses, it is the judgment of management that the allowance for credit
          losses reflected in the statements of condition is adequate to absorb
          estimated losses which may exist in the loan portfolio as of the dates
          of the statements of condition.

          Real Estate Acquired by Foreclosure - The Bank records real estate
          -----------------------------------
          acquired by foreclosure at the lesser of the outstanding loan amount
          (including accrued interest, if any) or fair value, less estimated
          costs to sell, at the time of foreclosure. Adjustments are made to
          reflect declines in value subsequent to acquisition, if any, below the
          recorded amounts. Operating expenses of such properties, net of
          related income, and gains and losses on their disposition are included
          in other non-interest expense.

          Premises and Equipment - Land is carried at cost. Premises and
          ----------------------
          equipment are carried at cost less accumulated depreciation and
          amortization. Depreciation expense is computed principally using the
          straight-line method of accounting over the estimated useful lives of
          the assets. Leasehold improvements are amortized straight-line over
          the periods of the leases or the estimated useful lives, whichever is
          shorter.

          Goodwill and Other Intangible Assets - The adoption of Statement of
          ------------------------------------
          Financial Accounting Standard (SFAS) No. 142 by Paradigm, effective
          January 1, 2002, will eliminate the regular amortization of purchased
          goodwill on the Bank's books. Paradigm recognized amortization expense
          for purchased goodwill of $195,000 and $221,000 for the years ended
          December 31, 2001 and 2000, respectively which will not recur in 2002
          under this standard. Instead, this new standard will require a regular
          assessment for impairment of goodwill, and a write down of the
          goodwill if impairment occurs.

          Income Taxes - Paradigm accounts for and reports income taxes in
          ------------
          accordance with SFAS No. 109, "Accounting for Income Taxes." Applying
          SFAS No. 109, deferred tax assets and liabilities are recognized for
          temporary differences caused when the tax basis of an asset or
          liability differs from that reported in the consolidated financial
          statements, and for carryforwards for tax credits and tax losses.
          Deferred tax assets and liabilities are measured using enacted tax
          rates expected to apply to taxable income in the years in which those
          temporary differences are expected to be recovered or settled.
          Deferred tax expense or benefit is recognized for the change in the
          asset or liability during the year.

          Earnings Per Share (EPS) - Paradigm accounts for EPS in compliance
          ------------------------
          with SFAS No. 128, Earnings per Share. Under SFAS No. 128, because it
          has potential common shares, the Company has a complex capital
          structure and must disclose both basic and diluted EPS. Basic EPS is
          computed by dividing consolidated net income available to common
          shareholders by the weighted-average number of common shares
          outstanding for the year. Diluted EPS reflects the potential dilution
          that could occur if all dilutive securities and other contracts to
          issue common stock were exercised or converted into common stock or
          resulted in the issuance of common stock that then shared in the
          consolidated net income of the Company.

--------------------------------------------------------------------------------

NOTE A    ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING
          POLICIES (continued)

          Weighted-average shares outstanding were 2,375,000 shares for the
          years ended December 31, 2001 and 2000. Because recent sales have not
          exceeded the strike price for options, there were no material dilutive
          securities as of December 31, 2001 and 2000.

          Stock-Based Compensation - The Company accounts for stock-based
          ------------------------
          compensation under SFAS No. 123, Accounting for Stock-Based
          Compensation. Under the provisions of SFAS No. 123, companies may
          elect to account for stock-based compensation plans using a fair-value
          method or may measure compensation expense for those plans using the
          intrinsic value method prescribed in Accounting Principles Board
          Opinion No. 25, "Accounting for Stock Issued to Employees" and related
          Interpretations. The Company has elected to use the intrinsic value
          method to account for its stock-based compensation plans. SFAS No. 123
          requires companies electing to use the intrinsic value method to make
          certain pro forma disclosures (see Notes M and N).

          Statements of Cash Flows - Cash and cash equivalents include cash on
          ------------------------
          hand, amounts due from banks, interest-bearing deposits in financial
          institutions with remaining maturities of 90 days or less, and federal
          funds sold; generally, federal funds are sold for one-day periods.

          Comprehensive Income - The Company reports comprehensive income in
          --------------------
          accordance with SFAS No. 130, Reporting Comprehensive Income. SFAS No.
          130 requires the reporting of comprehensive income in addition to net
          income from operations. Comprehensive income is a more inclusive
          financial reporting methodology that includes disclosure of certain
          financial information affecting stockholders' equity that is not
          recognized in the calculation of net income.

           Net Deferred Tax Asset                          ============    ============



          Paradigm acquired federal income tax net operating loss (NOL)
          carryforwards of about $973,000 in the purchase of First National Bank
          of Dayton in 1997, which were not recognized prior to December 1999
          due to Paradigm's subchapter S tax filing status. The carryforwards
          were recognized in December 1999 when Paradigm changed from an S
          corporation to C corporation tax filing status. Also in December 1999,
          due to the Internal Revenue Code regulations regarding acquired
          carryforwards and due to uncertainty about the realization of adequate
          taxable income before the carryforwards expire, a valuation allowance
          was established for the deferred tax asset related to the
          carryforwards.

          During 2000, management reevaluated the deferred tax asset related to
          the acquired NOL carryforwards. Paradigm earned significant taxable
          income for 2000 and established a stable operating environment after
          its 1999 purchase of Dayton State Bank, reducing the previous
          uncertainty regarding realization of sufficient taxable income.
          Therefore, it is considered more likely than not that the
          carryforwards will be realized before they expire. Accordingly, the
          valuation allowance amounting to $330,799 was reversed in 2000 and
          goodwill was reduced by this amount. No reduction in income tax
          expense resulted from this valuation allowance reversal.

          At December 31, 2001, Paradigm has NOL carryforwards of about
          $709,000, which expire during the period 2004 through 2007.
          Realization of the NOL carryforwards is limited to approximately
          $132,000 annually.

NOTE J    CASH FLOW HEDGE

          In 2000, Paradigm purchased an interest rate floor for $195,000 to
          hedge against the effect of future declines in interest rates for the
          floating rate loan portfolio. This hedge was accounted for as a cash
          flow hedge in compliance with SFAS No. 133, as amended by SFAS No.
          138. The terms of the floor called for seven quarterly payments to
          Paradigm based on a notional amount of $30 million if the 90-day LIBOR
          interest rate was below 7% from October 25, 2000 through April 2002.
          In the fourth quarter of 2000, Paradigm sold this hedge and realized a
          pre-tax gain of $105,000 over the original purchase price.

NOTE K    EMPLOYEE BENEFITS

          The Company has an employee tax-deferred savings plan (401(k) Plan)
          under the Internal Revenue Code available to substantially all
          employees. Funds contributed by employees under the 401(k) Plan are
          invested in a variety of investment options at the direction of the
          employee. Contributions made by the Company to the plan are in cash
          and in such amounts, within certain limitations, as management may
          authorize. The 401(k) Plan expense totaled $126,583 and $74,717 for
          the years ended December 31, 2001 and 2000, respectively.

NOTE L    DEFERRED COMPENSATION PLAN

          The Company has deferred compensation agreements with certain
          employees that provide for payment of $25,000 per year to those
          employees or their surviving beneficiaries for a period of ten years
          beginning at retirement. For these employees, the Company has whole
          life insurance policies to provide a cash value to cover part of the
          deferred compensation payments, or in case of the employee's death, to
          pay the beneficiaries.

          Deferred compensation expense is recorded over the estimated remaining
          period of employment. The liability for services previously performed
          totaled approximately $194,000 and $360,000 at December 31, 2001 and
          2000, respectively, and is included in other liabilities in the
          accompanying statements of condition. Cash value of about $485,000 and
          $611,000 accumulated in the life insurance policies purchased for
          these agreements as of December 31, 2001 and 2000, respectively, is
          included in other assets on the accompanying statements of condition.

NOTE M    STOCK APPRECIATION RIGHTS

          Paradigm maintains a stock appreciation rights (SAR) program to offer
          eligible employees an opportunity to acquire or increase their
          proprietary interests in Paradigm and provide additional incentive to
          contribute to its performance and growth. The Board of Directors had
          reserved 150,000 shares under the Plan, however, during 2000 the Board
          elected to discontinue issuing any additional stock appreciation
          rights under this program.

          Paradigm has reported compensation costs for SARs of $68,000 and
          $79,000 in salaries and employee benefits for the years ended December
          31, 2001 and 2000, respectively. Reported compensation cost for SARs
          is measured as the vested portion of the excess, if any, of the market
          price of Paradigm stock at the reporting date over the amount an
          employee must pay to exercise the SARs.

          The pro forma SARs compensation expense computed under SFAS No. 123
          equaled $40,000 and $41,000 for 2001 and 2000, respectively. The pro
          forma change in net earnings, if this compensation expense had been
          recorded instead of the amounts actually reported, would be an
          increase in net earnings after tax of about $18,000 and $24,000 for

NOTE N    STOCK OPTIONS

          In 1999, the Board of Directors and shareholders approved a Stock
          Option Plan (the Plan), which authorizes the issuance of up to 200,000
          shares of common stock for nonqualified and incentive stock options to
          employees and nonqualified stock options to non-employee directors.
          Outstanding options become exercisable cumulatively in five equal
          annual installments commencing one year from the grant date, or
          completely upon certain changes in control of the Company or the Bank.
          The options generally must be exercised within 10 years of the date of
          grant or no later than three months after the grantee's termination of
          employment, if earlier.

          The Plan also provides for the granting of restricted stock awards,
          stock appreciation rights, performance awards and phantom stock
          awards. Of these other awards, only stock appreciation rights have
          been granted (see Note M).

NOTE O       FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

             To meet the financing needs of its customers and to reduce its own
             exposure to fluctuations in interest rates, the Bank is party to
             various financial instruments with off-balance-sheet risk in the
             normal course of business. These financial instruments include
             commitments to extend credit and standby letters of credit. These
             instruments involve, to varying degrees, elements of credit and
             interest rate risk in excess of the amounts recognized in the
             statements of condition. The contract or notional amounts of the
             instruments reflect the extent of the Bank's involvement in
             particular classes of financial instruments. The Bank's exposure to
             credit loss in the event of nonperformance by the other party to
             the financial instrument for commitments to extend credit and
             standby letters of credit is represented by the contractual
             notional amount of these instruments. The Bank uses the same credit
             policies in making these commitments and conditional obligations as
             it does for on-balance-sheet instruments.

             The following is a summary of the various financial instruments
             whose contract amounts represent credit risk:

                                                      December 31, 2001 and 2000
--------------------------------------------------------------------------------

NOTE O       FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK (continued)

             Commitments to extend credit are agreements to lend to a customer
             as long as there is no violation of any condition established in
             the contract. Commitments generally have fixed expiration dates or
             other termination clauses and may require payment of a fee. Since
             many of the commitments are expected to expire without being fully
             drawn upon, the total commitment amounts disclosed above do not
             necessarily represent future cash requirements.

             The Bank evaluates each customer's creditworthiness on a
             case-by-case basis. The amount of collateral obtained, if
             considered necessary by the Bank upon extension of credit, is based
             on management's credit evaluation of the customer.

             Standby letters of credit are conditional commitments issued by the
             Bank to guarantee the performance of a customer to a third party.
             The credit risk involved in issuing letters of credit is
             essentially the same as that involved in extending loan facilities
             to their customers.

NOTE P       OPERATING LEASES

             The Bank leases banking and office facilities under operating
             leases with terms expiring at various dates, some of which contain
             renewal options. A summary of non-cancelable future operating lease
             commitments follows:

                                                         =============

             It is expected that in the normal course of business, leases that
             expire will be renewed or replaced by leases on other property or
             equipment. Rent expense under all non-cancelable operating lease
             obligations totaled about $315,000 and $191,000 for 2001 and 2000,
             respectively.

NOTE Q       COMMITMENTS AND CONTINGENCIES

             Litigation - Various lawsuits are pending against Paradigm arising
             ----------
             in the normal course of business. Paradigm management, after
             reviewing these lawsuits with outside legal counsel, considers that
             the aggregate liabilities, if any, will not be material to the
             consolidated financial statements.

                                                      December 31, 2001 and 2000
--------------------------------------------------------------------------------

NOTE R            REGULATORY MATTERS

                  Paradigm and the Bank are subject to various regulatory
                  capital requirements administered by their primary federal
                  regulators. The regulations include, but are not limited to,
                  the payment of dividends and minimum capital requirements. The
                  payment of dividends by the Bank is limited to the sum of the
                  current year's earnings plus undistributed earnings from the
                  prior two years. As of December 31, 2001, Paradigm had
                  approximately $2,469,000 of retained earnings that could be
                  paid under this restriction without regulatory approval.

                  Any institution that fails to meet its minimum capital
                  requirements is subject to certain mandatory and possibly
                  discretionary actions by regulators that could have a direct
                  material effect on the financial statements of the Company and
                  the Bank. Under the capital adequacy guidelines and the
                  regulatory framework for prompt corrective action, the Bank
                  must meet specific capital guidelines based on the Bank's
                  assets, liabilities and certain off-balance-sheet items as
                  calculated under regulatory accounting practices. Capital
                  amounts and classification are also subject to qualitative
                  judgments by the regulators about components, risk weightings
                  and other factors.

                  To meet the capital adequacy requirements, the Company and the
                  Bank must maintain minimum capital amounts and ratios as
                  defined in the regulations. Management believes, as of
                  December 31, 2001, that the Company and the Bank met all
                  capital adequacy requirements to which it was subject.

                  As of December 31, 2001, the most recent notifications from
                  the Federal Deposit Insurance Corporation which occurred in
                  the year 2001, the Bank was categorized as well capitalized
                  under the regulatory framework for prompt corrective action.
                  To be categorized as well capitalized, the Bank must maintain
                  minimum total risk- based, Tier I risk-based, and Tier I
                  leverage ratios as set forth in the table below. There are no
                  conditions or events since that notification that management

NOTE T    DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

          The following disclosure of the estimated fair value of financial
          instruments is made in accordance with the requirements of SFAS No.
          107, Disclosures About Fair Value of Financial Instruments. The
          estimated fair value amounts have been determined by management using
          available market information and appropriate valuation methodologies.
          However, considerable judgment is necessarily required in interpreting
          market data to develop the estimates of fair value. Accordingly, the
          estimates presented herein are not necessarily indicative of the
          amounts that could be realized in a current market exchange. The use
          of different market assumptions and/or estimation methodologies may
          have a material effect on the estimated fair value amounts. The
          following methods and assumptions were used to estimate the fair value
          of each class of financial instruments for which it is practicable to
          estimate that value.

          Cash and Cash Equivalents - For these short-term instruments, the
          -------------------------
          carrying amount is a reasonable estimate of fair value.

          Investment Securities - For securities held as investments, fair value
          ---------------------
          equals quoted market price, if available. If a quoted market price is
          not available, fair value is estimated using the quoted market price
          for similar securities.

NOTE T    DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS (continued)

          Loan Receivables - The fair value of loans is estimated by discounting
          ----------------
          the future cash flows using the current rates at which similar loans
          would be made to borrowers with similar credit ratings and for the
          same remaining maturities.

          Deposit Liabilities - The fair value of demand deposits, savings
          -------------------
          accounts and certain money market deposits is the amount payable on
          demand at the reporting date. The fair value of fixed-maturity
          certificates of deposit is estimated using the rates currently offered
          for deposits of similar remaining maturities.

          Due to Former Shareholders and Other Liabilities - The fair value of
          ------------------------------------------------
          due to former shareholders and other liabilities is the amount payable
          on demand at the reporting date. Because it is anticipated that these
          amounts will be paid in the near term, the carrying value is a
          reasonable estimate of fair value.

          The estimated fair values of financial instruments are as follows (in
          thousands):

          The fair value estimates are based on pertinent information available
          to management as of December 31, 2001 and 2000. Although management is
          not aware of any factors that would significantly affect the estimated
          fair value amounts, such amounts have not been comprehensively
          revalued for purposes of these financial statements since that date
          and, therefore, current estimates of fair value may differ
          significantly from the amounts presented herein.

          Escrow Agreement - In January 2002, the funds held in escrow and
          ----------------
          included in the amount due to former shareholders, pursuant to the
          terms of the purchase agreement between Paradigm and the selling
          Dayton shareholders, were distributed according to the terms of the
          escrow agreement. As agreed upon by Paradigm and the escrow agent, the
          funds were disbursed according to the payment status of the loans
          subject to this agreement. Of the approximate $468,000 held in escrow
          by Paradigm, $212,000 was distributed to the former Dayton
          shareholders and $256,000 was retained by Paradigm and the funds were
          added to the Bank's reserve for credit losses as stipulated by the
          terms of the escrow agreement.

other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as set forth below:

                                  INTRODUCTION

         A. This Agreement provides for the merger of Paradigm with and into

Agreement and a Plan of Merger by and between Prosperity and Paradigm, a copy of
which is attached hereto as Exhibit A and all of the terms of which are

corporation and wholly-owned subsidiary of Prosperity ("Delaware Company"), (the
"Delaware Merger"), all pursuant to an Agreement of Merger by and between the
Delaware Company and Paradigm Delaware, a copy of which is attached hereto as
Exhibit B.




         C. After the Effective Time of the Merger and on the same date as the

as Exhibit C.

                                 I. THE MERGER

         Section 1.1 The Merger. Paradigm shall be merged with and into

"Continuing Company" whenever reference is made to it at or after the Effective
Time) under the Articles of Incorporation of Prosperity pursuant to the
provisions of, and with the effect provided in Article 5 of the Texas Business
Corporation Act ("TBCA").

         Section 1.2 Articles of Incorporation, Bylaws and Facilities of
Continuing Company. At the Effective Time and until thereafter amended in
accordance with applicable law, the Articles of Incorporation of Continuing
Company shall be the Articles of Incorporation of Prosperity as in effect
immediately prior to the Effective Time. Until altered, amended or repealed as
therein provided and in the Articles of Incorporation of Continuing Company, the
Bylaws of Continuing Company shall be the Bylaws of Prosperity as in effect
immediately prior to the Effective Time. The established offices and facilities
of Paradigm immediately prior to the Merger shall become established offices and
facilities of the Continuing Company. Unless and until changed by the Board of
Directors of Continuing Company, the main office of Prosperity as of the
Effective Time shall become the main office of the Continuing Company. Until
thereafter changed in accordance with law or the Articles of Incorporation or
Bylaws of Continuing Company, all corporate acts, plans, policies, contracts,
approvals and authorizations of Paradigm and Prosperity and their respective
shareholders, boards of directors, committees elected or appointed thereby,
officers and agents, which were valid and effective immediately prior to the
Effective Time, shall be taken for all purposes as the acts, plans, policies,
contracts, approvals and authorizations of Continuing Company and shall be as
effective and binding thereon as the same were with respect to the Paradigm and
Prosperity, respectively, as of the Effective Time.

         Section 1.3 Effect of Merger. At the Effective Time, the corporate
existence of Paradigm and Prosperity shall, as provided in the provisions of law
heretofore mentioned, be merged and continued in Continuing Company, and
Continuing Company shall be deemed to be a continuation in entity and identity
of Paradigm and Prosperity. All rights, franchises and interests of Paradigm and
Prosperity, respectively, in and to any type of property and choses in action
shall be transferred to and vested in Continuing Company by virtue of such
Merger without any deed or other transfer. Continuing Company, without any order
or other action on the part of any court or otherwise, shall hold and enjoy all
rights of property, franchises and interest, including appointments,
designations and nominations, and all other rights and interests as trustee,
executor, administrator, transfer agent or registrar of stocks and bonds,
guardian of estates, assignee, receiver and committee of estates and lunatics,
and in every other fiduciary capacity, in the same manner and to the same extent
as such rights, franchises, and interests were held or enjoyed by Paradigm and
Prosperity, respectively, as of the Effective Time.

                                      A-2



         Section 1.4   Liabilities of Continuing Company. At the Effective Time,
Continuing Company shall be liable for all liabilities of Paradigm and
Prosperity. All debts, liabilities, obligations and contracts of Paradigm and of
Prosperity, respectively, matured or unmatured, whether accrued, absolute,
contingent or otherwise, and whether or not reflected or reserved against on
balance sheets, books of account, or records of Paradigm or Prosperity, as the
case may be, shall be those of Continuing Company and shall not be released or
impaired by the Merger. All rights of creditors and other obligees and all liens
on property of either Paradigm or Prosperity shall be preserved unimpaired
subsequent to the Merger.

         Section 1.5   Ratification by Shareholders. Subject to the terms of
this Agreement, this Agreement shall be submitted to the shareholders of
Paradigm in accordance with applicable provisions of law and the Articles of
Incorporation and Bylaws of Paradigm. Paradigm and Prosperity shall proceed
expeditiously and cooperate fully in the procurement of any other consents and
approvals and the taking of any other actions in satisfaction of all other
requirements prescribed by law or otherwise necessary for consummation of the
Merger on the terms herein provided, including, without limitation, the
preparation and submission of all necessary filings, requests for waivers and
certificates with the Securities and Exchange Commission ("SEC"), Board of
Governors of the Federal Reserve System ("Federal Reserve"), the Federal Deposit
Insurance Corporation ("FDIC") and the Texas Department of Banking (the "Banking
Department.")

         Section 1.6   Tax Consequences. It is intended by the parties hereto
that the Merger shall constitute a reorganization within the meaning of Section
368(a) of the Code, and the parties hereto hereby adopt this Agreement as a
"plan of reorganization" within the meaning of Sections 1.368-2(g) and
1.368-3(a) of the Treasury Regulations promulgated thereunder.

                II. MERGER CONSIDERATION AND EXCHANGE PROCEDURES

         Section 2.1   Merger Consideration.

                (a)    Each share of the Paradigm Common Stock issued and
outstanding immediately prior to the Effective Time, other than Dissenting
Shares (as defined in Section 2.5 of the Agreement), shall, by virtue of the
Merger and without any action on the part of the holder thereof, be cancelled
and converted into and represent the right to receive, upon surrender of the
certificate representing such share, that number of shares of common stock,
$1.00 par value, of Prosperity ("Prosperity Common Stock") equal to the Total
Exchange Ratio or, if applicable, the Adjusted Total Exchange Ratio, as set
forth in Section 2.2 (the "Merger Consideration"), without interest thereon;
provided, however, that a portion of such shares will be distributed in trust
subject to the holdback rights set forth in Section 2.2(d) hereof.

                (b)    Each share of Paradigm Common Stock held in the treasury
of Paradigm and each share of Paradigm Common Stock owned by any direct or
indirect wholly owned Subsidiary of Paradigm immediately prior to the Effective
Time shall be cancelled without any conversion and no payment or distribution
shall be made with respect thereto.

                (c)    Notwithstanding anything in this Agreement to the
contrary, Prosperity will not issue any certificates or scrip representing
fractional shares of Prosperity Common Stock

                                       A-3



otherwise issuable pursuant to the Merger. In lieu of the issuance of any such
fractional shares, Prosperity shall pay to each former holder of Paradigm Common
Stock otherwise entitled to receive such fractional share an amount of cash
determined by multiplying (i) the average closing price per share of Prosperity
Common Stock on The Nasdaq Stock Market, Inc. National Market System ("Nasdaq")
(as reported by The Wall Street Journal or, if not reported thereby, another
alternative source as chosen by Prosperity) on the trading day immediately prior
to the day during which the Effective Time occurs by (ii) the fraction of a
share of Prosperity Common Stock which such holder would otherwise be entitled
to receive pursuant to this Section 2.1.

     Section 2.2   Determination and Adjustment of Exchange Ratio.

            (a)    The aggregate number of shares of Prosperity Common Stock to
be exchanged for each share of Paradigm Common Stock shall be adjusted
appropriately to reflect any change in the number of shares of Prosperity Common
Stock by reason of any stock dividends or splits, reclassification,
recapitalization or conversion with respect to Prosperity Common Stock, received
or to be received by holders of Prosperity Common Stock, when the record date or
payment occurs prior to the Effective Time.

            (b)    Unless otherwise adjusted as provided in Section 2.2(c), each
share of Paradigm Common Stock outstanding prior to the Effective Time of the
Merger shall be converted into and exchanged for the right to receive up to
0.54329 shares of Prosperity Common Stock (the "Total Exchange Ratio") in the
following manner: (i) each shareholder will receive 0.52745 shares of Prosperity
Common Stock at Closing (the "Closing Exchange Ratio") and (ii) each shareholder
will have the right to receive up to 0.01584 shares of Prosperity Common Stock
which will be distributed in trust as further provided in Section 2.2(d) (the
"Holdback Exchange Ratio"). Subject to any adjustment as provided in Section
2.2(c), (i) an aggregate of 1,252,687 shares of Prosperity Common Stock, less
any shares that would otherwise be distributed to shareholders who exercise
dissenters' rights, shall be distributed to shareholders of Paradigm at closing
(collectively, the "Closing Shares") and (ii) an aggregate of up to 37,635
shares of Prosperity Common Stock, less any shares that would otherwise be
distributed to shareholders who exercise their dissenters' rights, shall be
distributed in trust for possible future issuance (collectively, the "Holdback
Shares") as set forth in Section 2.2(d).

            (c)    The Total Exchange Ratio may, at the option of Prosperity, be
adjusted ("Adjusted Total Exchange Ratio") if (i) the average of the closing
price per share of Prosperity Common Stock ("Measurement Price") on Nasdaq (as
reported by The Wall Street Journal or, if not reported thereby, another
alternative source as chosen by Prosperity) during the period of the ten
consecutive trading days ending on the third trading day immediately prior to
the Closing Date ("Price Measurement Period") is less than $24.41 per share and
(ii) the percentage difference between $32.55 and the Measurement Price is
greater than 10% lower than the percentage decrease between the closing price of
the KBW Bank Index on April 26, 2002 and the average closing price of the KBW
Bank Index during the Price Measurement Period. If adjusted, each share of
Paradigm Common Stock outstanding immediately prior to the Effective Time will
be converted and exchanged into the number of shares of Prosperity Common Stock
determined by dividing the Adjusted Prosperity Shares by the number of shares of
Paradigm Common Stock then outstanding. The "Adjusted Prosperity Shares" shall
be a number equal to $31,500,000 divided by the Measurement Price. If Prosperity
elects not to adjust the Total

                                       A-4



Exchange Ratio, Paradigm may terminate this Agreement as provided in Section
9.1(d) hereof. If Prosperity elects to adjust the Total Exchange Ratio, the
Closing Exchange Ratio and the Holdback Exchange Ratio shall be adjusted
accordingly.

               (d)    The Holdback Shares shall be distributed in trust to PRSP
Bank Trust Department, as trustee ("PRSP Trustee"), to be held (the "Escrow")
for possible future distribution to Paradigm shareholders or to be returned to
Prosperity for cancellation, as described in the Holdback Escrow Agreement
referred to in Section 2.8 hereof. Each former Paradigm shareholder (other than
any shareholder who has validly exercised such shareholder's dissenters' rights)
shall be entitled to receive a distribution of Holdback Shares equal to the
number of Holdback Shares to be distributed multiplied by a fraction the
numerator of which is the number of shares of Paradigm Common Stock held by that
shareholder immediately prior to the Effective Time, and the denominator of
which is the total number of Paradigm shares outstanding immediately prior to
Effective Time (excluding for these purposes any shares attributable to
shareholders who have validly exercised their dissenters' rights). The rights
under the trust, including the right to receive any Holdback Shares, will not be
transferable or assignable by the Paradigm shareholders other than by will or by
the laws of descent and distribution in the case of a natural person, or in the
case of a trust or entity, to any successor trustee or successor entity,
including without limitation, the distribution to the beneficial owners in
accordance with the terms of the governing documents or under applicable law.
The Holdback Shares are being distributed in trust in part to protect Prosperity
from any actual or potential losses arising out of or in any manner related to
losses incurred by Prosperity in connection with any of the loans of Paradigm
set forth in Schedule 2.2(d). As of the date hereof, the aggregate outstanding
balance of the Scheduled Loans is $1,877,839 and the value of the Holdback
Shares, based on a price of $32.55 per share, was $1,225,000 ("Holdback Share
Value").

               (e)    For purposes of this Agreement, the aggregate number of
Closing Shares and Holdback Shares as stated in Section 2.2(b) (including for
these purposes any shares that would be distributed to Paradigm shareholders but
for their exercise of dissenters' rights of appraisal), prior to any adjustment
pursuant to Section 2.2(c), and whether or not all Holdback Shares are in fact
actually distributed, is referred to herein as the "Aggregate Maximum Number of
Shares."

          Section 2.3 Conversion of Paradigm Stock Options. (a) At the Effective
Time, each option to acquire shares of Paradigm Common Stock which is
outstanding and unexercised immediately prior thereto ("Paradigm Stock Option")
pursuant to the Paradigm Bancorporation, Inc. 1999 Stock Incentive Plan
("Paradigm Stock Option Plan") shall, in accordance with its terms, be converted
(automatically and without any action on the part of the holder thereof) into an
option to purchase shares of Prosperity Common Stock in an amount and at an
exercise price determined as provided below (and otherwise subject to the terms
of the Paradigm Stock Option Plan and agreements evidencing the grants
thereunder):

                      (i) The number of shares of Prosperity Common Stock to be
subject to the new option shall be equal to the number of shares of Paradigm
Common Stock subject to the original option multiplied by the Total Exchange
Ratio or, if applicable, the Total Adjusted Exchange Ratio; and

                                      A-5



                       (ii) The exercise price per share of Prosperity Common
Stock under the new option shall be equal to the exercise price per share of
Paradigm Common Stock under the original option divided by the Total Exchange
Ratio or, if applicable, the Adjusted Total Exchange Ratio.

               (b)     The adjustment provided herein with respect to any
options which are "incentive stock options" as defined in Section 422 of the
Internal Revenue Code, shall be and is intended to be effected in a manner which
is consistent with Section 424(a) of the Internal Revenue Code. The duration and
other terms of the new option shall be the same as the original option except
that all references to Paradigm shall be deemed to be references to Prosperity.

          Section 2.4  Stock Appreciation Rights.

               (a)     Immediately prior to the Effective Time, all rights with
respect to the Stock Appreciation Rights ("Paradigm SARs") granted pursuant to
the Paradigm 1998 Stock Appreciation Rights Plan ("Paradigm SAR Plan") which are
listed and described (including exercise prices, vesting schedules, expiration
dates, holders of and numbers of SARs) in Schedule 2.4(a), which are outstanding
immediately prior to the Effective Time shall be cancelled immediately prior to
the Effective Time and shall be converted into the right of each holder thereof
to receive for each Paradigm SAR cash in an amount equal to the difference
between (i) the average of the high and low sale prices of a share of Prosperity
Common Stock on Nasdaq on the second trading day immediately prior to the
Closing Date multiplied by the Total Exchange Ratio, or if applicable, the
Adjusted Total Exchange Ratio and (ii) the exercise price of each Paradigm SAR
under such holder's SAR Agreement.

               (b)     Paradigm shall procure from each holder of Paradigm SARs,
and shall deliver to Prosperity at the Closing, an executed acknowledgement of
the treatment and disposition of such holder's Paradigm SARs as provided for
under this Section 2.4 and Section 10.9.

          Section 2.5  Dissenting Shares. Each share of Paradigm Common Stock
issued and outstanding immediately prior to the Effective Time, the holder of
which has not voted in favor of the Merger and who has delivered a written
demand for payment of the fair value of such shares within the time and in the
manner provided in Article 5.12 of the TBCA, is referred to herein as a
"Dissenting Share." Notwithstanding anything in this Agreement to the contrary,
Dissenting Shares shall not be converted into or represent the right to receive
the Merger Consideration pursuant to Section 2.1 of this Agreement unless and
until such holder shall have failed to perfect or shall have effectively
withdrawn or lost his right to appraisal and payment under the TBCA. If any such
holder shall have so failed to perfect or shall have effectively withdrawn or
lost such right, such holder's Dissenting Shares shall thereupon be deemed to
have been converted into and to have become exchangeable for, at the Effective
Time, the right to receive the Merger Consideration without any interest
thereon.

          Section 2.6  Exchange Agent. Immediately prior to the Closing Date,
Prosperity shall deposit or cause to be deposited in trust with Computershare
Investor Services, Inc., Denver, Colorado (the "Exchange Agent") (i)
certificates representing shares of Prosperity Common Stock and (ii) cash, each
in an aggregate amount estimated to be sufficient to make the payments

                                      A-6



of the Merger Consideration set forth in Section 2.1 of this Agreement and to
make the appropriate cash payments (A) to holders of Dissenting Shares pursuant
to Section 2.5 hereof, if any, and (B) holders of a fraction of a share of
Prosperity Common Stock (such amounts being hereinafter referred to as the
"Exchange Fund"). The Exchange Fund shall not be used for any other purpose,
except as provided in this Agreement.

          Section 2.7   Exchange Procedures.

               (a)      At least ten (10) days prior to the Closing Date,
Paradigm shall deliver to Prosperity a list of Paradigm's shareholders which
shall include each shareholder's name, address and the number of shares of
Paradigm Common Stock owned.

               (b)      Promptly after the Effective Time, the Exchange Agent
shall mail to each record holder of an outstanding certificate or certificates
which as of the Effective Date represented shares of Paradigm Common Stock (the
"Certificates"), a form letter of transmittal which will specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon proper delivery of the Certificates to the Exchange Agent and contain
instructions for use in effecting the surrender of the Certificates for payment
therefor. Upon surrender to the Exchange Agent of a Certificate, together with
such letter of transmittal duly executed, the holder of such Certificate shall
be entitled to receive in exchange therefor the amount of cash and number of
shares of Prosperity Common Stock provided in Section 2.1 hereof, and such
Certificate shall forthwith be cancelled. Prosperity shall provide the Exchange
Agent with certificates for Prosperity Common Stock, as requested by the
Exchange Agent, for the number of shares provided in Section 2.1 or, if
applicable, Section 2.2 hereof. No interest will be paid or accrued with respect
to cash payable upon surrender of the Certificate in accordance with this
Article II. Until surrendered in accordance with the provisions of this Section
2.7, each Certificate (other than Certificates representing Dissenting Shares)
shall represent for all purposes the right to receive the Merger Consideration
without any interest thereon.

               (c)      Former shareholders of Paradigm shall be entitled to
vote after the Effective Time at any meeting of Prosperity's shareholders the
number of shares of Prosperity Common Stock into which their shares are
converted, regardless of whether such shareholders of Paradigm have surrendered
their Certificates in exchange therefor.

               (d)      No dividends or other distributions declared after the
Effective Time with respect to shares of Prosperity Common Stock and payable to
the holders thereof shall be paid to the holder of a Certificate until such
holder surrenders such Certificate to the Exchange Agent in accordance with this
Section 2.7. After the surrender of a Certificate in accordance with this
Section 2.7, the holder thereof shall be entitled to receive any such dividends
or other distributions, without interest thereon, which had become payable after
the Effective Time with respect to the shares of Prosperity Common Stock
represented by such Certificate. Any dividends (including stock dividends) or
other amounts attributable to Holdback Shares held in trust pursuant to Section
2.2(d) hereof, shall accrue during the holdback period set forth in the Holdback
Escrow Agreement and shall be distributed to Paradigm shareholders, without
interest thereon, at the same time and in the same proportion as any Holdback
Shares are distributed to

                                      A-7



Paradigm shareholders. No dividends will be paid with respect to any Holdback
Shares which are not distributed to Paradigm shareholders.

               (e) After the Effective Time, the stock transfer ledger of
Paradigm shall be closed and there shall be no transfers on the stock transfer
books of Paradigm of the shares of Paradigm Common Stock which were outstanding
immediately prior to such time of filing. If, after the Effective Time,
Certificates are presented to Prosperity, they shall be promptly presented to
the Exchange Agent and exchanged as provided in this Section 2.7.

               (f) Any portion of the Exchange Fund (including the proceeds of
any investments thereof) that remains unclaimed by the shareholders of Paradigm
for six months after the Exchange Agent mails the letter of transmittal pursuant
to Section 2.7(b) shall be delivered to Prosperity upon demand, and any
shareholders of Paradigm who have not theretofore complied with the exchange
procedures in this Article II shall look to Prosperity only, and not the
Exchange Agent, for the payment of any Merger Consideration in respect of such
shares.

               (g) If any certificate representing shares of Prosperity Common
Stock is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it shall be a condition of the
issuance thereof that the Certificate so surrendered shall be appropriately
endorsed (or accompanied by an appropriate instrument of transfer) and otherwise
in proper form (reasonably satisfactory to Prosperity) for transfer, and that
the person requesting such exchange shall pay to the Exchange Agent in advance
any transfer or other taxes required by reason of the issuance of a certificate
representing shares of Prosperity Common Stock in any name other than that of
the registered holder of the Certificate surrendered, or required for any other
reason, or shall establish to the satisfaction of the Exchange Agent that such
tax has been paid or not payable.

               (h) None of Prosperity, Paradigm, the Exchange Agent or any other
person shall be liable to any former holder of shares of Paradigm Common Stock
for any Prosperity Common Stock (or dividends or distributions with respect
thereto) or cash properly delivered to a public official pursuant to applicable
abandoned property, escheat or similar laws.

               (i) In the event any Certificate shall have been lost, stolen or
destroyed, then upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
Prosperity or the Exchange Agent, the posting by such person of a bond in such
amount as Prosperity or the Exchange Agent may direct as indemnity against any
claim that may be made against the Continuing Company with respect to such
Certificate, the Exchange Agent will issue in exchange for such lost, stolen or
destroyed Certificate the shares of Prosperity Common Stock and cash in lieu of
a fractional share interest deliverable in respect thereof pursuant to this
Agreement.

      Section 2.8  Paradigm Shareholder Representative.

               (a) Walter G. Finger (the "Paradigm Shareholder Representative")
is hereby irrevocably appointed as the attorney in fact and agent of the
Paradigm shareholders effective immediately prior to Closing (other than
Paradigm shareholders who properly and fully exercise

                                      A-8



their dissenters' rights) and any person to whom rights to the Holdback Shares
have been properly assigned under Section 2.2(d) (individually, a "Holdback
Beneficial Owner" and collectively, the "Holdback Beneficial Owners") for all
purposes of the Holdback Escrow Agreement, attached hereto as Exhibit D and made
a part hereof, to act as agent for the Paradigm shareholders to facilitate the
consummation of the transactions herein described and to facilitate distribution
of consideration to the Holdback Beneficial Owners. Prosperity shall be entitled
to rely upon the Paradigm Shareholder Representative's authority to act on
behalf of the Holdback Beneficial Owners in his capacity as such agent. The
Paradigm Shareholder Representative shall have authority on behalf of the
Paradigm shareholders, and shall promptly and completely exercise such authority
in a timely fashion to:

               (i)   participate in, represent and bind the Holdback Beneficial
Owners in all respects with respect to any arbitration or legal proceeding
relating to the Holdback Escrow Agreement, including, without limitation, the
defense and settlement of any matter, and the calculation thereof for every
purpose thereunder, consent to jurisdiction, to enter into any settlement, and
to entry of judgment, each with respect to any or all of the Holdback Beneficial
Owners; provided, however, the Paradigm Shareholder Representative shall have no
authority under this Agreement or the Holdback Escrow Agreement to bind any
Holdback Beneficial Owner to pay or return any money or property other than the
money and/or Holdback Shares that are then being held by the PRSP Trustee under
the Holdback Escrow Agreement;

               (ii)  receive, accept and give notices and other communications
relating to the Holdback Escrow Agreement;

               (iii) take any action that the Paradigm Shareholder
Representative deems necessary or desirable in order to fully effectuate the
transactions contemplated by the Holdback Escrow Agreement; and

               (iv)  execute and deliver any instrument or document that the
Representative deems necessary or desirable in the exercise of his authority
under this Section 2.8.

          (b)  Those Holdback Beneficial Owners who have the right to receive a
majority of the Prosperity Common Stock that may distributed to the Holdback
Beneficial Owners out of the Escrow (a "Majority in Interest"), may at any time
and by written action delivered to Prosperity, remove the Paradigm Shareholder
Representative or any successor thereto, but such removal shall be effective
only upon the replacement of such Paradigm Shareholder Representative or
successor by a new Paradigm Shareholder Representative designated, by written
notice delivered to Prosperity, by those Holdback Beneficial Owners who hold a
Majority in Interest; provided, however, that any such notice shall be only
effective upon actual receipt by Prosperity. Any such written notice shall be
delivered to Prosperity in accordance with the notice provisions set forth
herein. If any Paradigm Shareholder Representative shall have died, become
incapacitated or unable to serve, those Holdback Beneficial Owners who, as of
immediately prior to the Effective Date, hold a Majority in Interest shall
promptly designate by written notice delivered to Prosperity, a replacement
Paradigm Shareholder Representative. Any reasonable costs and expenses incurred
by the Paradigm Shareholder Representative in connection with actions taken
pursuant to or permitted by this

                                      A-9



section will be borne, directly or indirectly, by the Holdback Beneficial Owners
and paid or reimbursed to the Paradigm Shareholder Representative pro rata. If a
Holdback Beneficial Owner does not pay or reimburse such costs and expenses, the
Paradigm Shareholder Representative may require that Holdback Shares or other
property which would otherwise be distributed to such Holdback Beneficial Owners
pursuant to the Holdback Escrow Agreement be distributed to the Paradigm
Shareholder Representative at any time in connection with such reimbursement.

          (c) The foregoing authority is granted and conferred in consideration
for the various agreements and covenants of Prosperity contained herein. In
consideration of the foregoing, and subject to the successorship provisions of
this section, this authorization granted to the Paradigm Shareholder
Representative shall not be terminated by any act of any of the Paradigm
shareholders or by operation of law, whether by death or incompetence of any
Holdback Beneficial Owner or by the occurrence of any other event. If after the
execution hereof, any such Holdback Beneficial Owners shall die or become
incompetent, the Paradigm Shareholder Representative is nevertheless authorized
and directed to exercise the authority granted in this section as if such death
or incompetence had not occurred and regardless of notice thereof. In addition
to the authority granted to the Shareholder Representative as attorney in fact
and agent for the Holdback Beneficial Owners, all the powers, rights and
responsibilities are also given to the Shareholder Representative directly under
the terms of this Agreement and the Holdback Escrow Agreement, and he or she
shall have all such powers, rights and responsibilities whether or not he or she
is or deemed to be the actual attorney in fact or agent for any Holdback
Beneficial Owner. The rights of each Paradigm Shareholder to the Holdback Shares
is subject to this Section 2.8 and the other terms and conditions of this
Agreement and the Holdback Escrow Agreement. The Paradigm Shareholder
Representative shall have no liability to any Holdback Beneficial Owner for any
act or omission or obligation hereunder, provided that such action or omission
is taken by the Paradigm Shareholder Representative in good faith and without
willful misconduct.

                 III. REPRESENTATIONS AND WARRANTIES OF PARADIGM

financial position and results of operations of Paradigm at the dates and for
the periods indicated in conformity with generally accepted accounting
principles ("GAAP") applied on a consistent basis, except for the Call Reports
which are in compliance with regulatory accounting principles.

            (c)   Except as set forth in Schedule 3.5(c), since March 31, 2002,
Paradigm has not had any obligations or liabilities, fixed or contingent, that
(i) have or might reasonably be expected to have, individually or in the
aggregate, a Material Adverse Effect on the Condition of Paradigm or (ii) are
not fully shown or provided for in the Paradigm Financial Statements or
otherwise disclosed in this Agreement, or in any of the documents delivered to
Prosperity. Since March 31, 2002, there have been no material changes in the
financial condition, assets, liabilities or business of Paradigm, other than
changes in the ordinary course of business, which individually or in the
aggregate have not had a Material Adverse Effect on the Condition of Paradigm.

            (d)   Except as set forth in Schedule 3.5(d), Paradigm has not
changed its independent auditing firm since December 31, 1997, and there has
been no disagreement (as such term is used in Item 304 of Regulation S-K under
the Securities Act) between Paradigm and its independent auditing firm since
December 31, 1997 concerning any aspect of the manner in which Paradigm
maintains its books and records or the manner in which it has reported upon its
financial condition and results of operations during such period.

     Section 3.6  Real Property Owned or Leased.

            (a)   Other than real property acquired through foreclosure or deed
in lieu of foreclosure, Schedule 3.6(a) contains a true, correct and complete
list of all real property owned or leased by Paradigm, Paradigm Delaware and the
Bank (the "Paradigm Real Property"). True and complete copies of all of its
deeds, leases and title insurance policies for, or other documentation
evidencing ownership of, the properties referred to in Schedule 3.6(a) and all
mortgages, deeds of trust and security agreements to which such property is
subject have been furnished or made available to Prosperity.

                                      A-13



            (b)   Except as set forth in Schedule 3.6(b), no lease with respect
to any Paradigm Real Property and no deed with respect to any Paradigm Real
Property contains any restrictive covenant that materially restricts the use,
transferability or value of such Paradigm Real Property. Each of such leases is
a legal, valid and binding obligation enforceable in accordance with its terms
(except as may be limited by bankruptcy, insolvency, moratorium, reorganization
or similar laws affecting the rights of creditors generally and the availability
of equitable remedies), and is in full force and effect; there are no existing
defaults by Paradigm, Paradigm Delaware and the Bank or the other party
thereunder and there are no allegations or assertions of such by any party under
such agreement or any events that with notice lapse of time or the happening or
occurrence of any other event would constitute a default thereunder.

            (c)   Except as set forth in Schedule 3.6(c), to the knowledge of
Paradigm, none of the buildings and structures located on any Paradigm Real
Property, nor any appurtenances thereto or equipment therein, nor the operation
or maintenance thereof, violates in any material manner any restrictive
covenants or encroaches on any property owned by others, nor does any building
or structure of third parties encroach upon any Paradigm Real Property, except
for those violations and encroachments which in the aggregate would not
reasonably be expected to cause a Material Adverse Effect on the Condition of
Paradigm. No condemnation proceeding is pending or, to Paradigm's knowledge,
threatened, which would preclude or materially impair the use of any Paradigm
Real Property in the manner in which it is currently being used.

            (d)   Except as set forth in Schedule 3.6(d), Paradigm and its
Subsidiaries have good and indefeasible title to, or a valid and enforceable
leasehold interest in, or a contract vendee's interest in, all Paradigm Real
Property, and such interest is free and clear of all liens, charges or other
encumbrances, except (i) statutory liens for amounts not yet delinquent or which
are being contested in good faith through proper proceedings and (ii) those
liens related to real property taxes, local improvement district assessments,
easements, covenants, restrictions and other matters of record which do not
individually or in the aggregate materially adversely affect the use and
enjoyment of the relevant real property.

            (e)   All buildings and other facilities used in the business of
Paradigm are adequately maintained and, are free from defects which would be
reasonably likely to materially interfere with the current or future use of such
facilities.

     Section 3.7  Personal Property. Paradigm and its Subsidiaries have good
title to, or a valid leasehold interest in, all personal property, whether
tangible or intangible, used in the conduct of their business (the "Paradigm
Personalty"), free and clear of all liens, charges or other encumbrances, except
(a) statutory liens for amounts not yet delinquent or which are being contested
in good faith through proper proceedings and (b) such other liens, charges,
encumbrances and imperfections of title as to not individually or in the
aggregate materially adversely affect the use and enjoyment of the relevant
Paradigm Personalty. Subject to ordinary wear and tear, the Paradigm Personalty
is in good operating condition and repair and is adequate for the uses to which
it is being put.

     Section 3.8  Environmental Laws. To the knowledge of Paradigm, Paradigm and
its Subsidiaries, and any properties or business owned or operated by any of
them, whether or not held in a fiduciary or representative capacity, are in
material compliance with all terms and

                                      A-14



conditions of all applicable federal and state Environmental Laws (as defined
below) and permits thereunder. Except as set forth in Schedule 3.8, (a) neither
Paradigm nor any of its Subsidiaries has received notice of or has knowledge of
any material violation of any Environmental Laws or of any placement, disposal
or release of any materials designated as Hazardous Materials (as defined below)
under the Environmental Laws in a manner that would result in a material claim
or lien against any of them under any Environmental Laws; (b) during the term of
ownership by Paradigm or any of its Subsidiaries no real estate currently owned,
operated, or leased (including any property acquired by foreclosure or deeded in
lieu thereof) by Paradigm or its Subsidiaries, or owned, operated or leased by
Paradigm or its Subsidiaries within the five years preceding the date of this

any similar provision of state, local, or foreign law), as a transferee or
successor, by contract, or otherwise.

            (g)    Schedule 3.10(g) sets forth the following information with
respect to Paradigm and its Subsidiaries as of the most recent practicable date
(as well as on an estimated pro forma basis as of the Closing Date giving effect
to the consummation of the transactions contemplated hereby): (i) the amount of
any net operating loss, net capital loss, unused investment or other credit,
unused foreign tax, or excess charitable contribution allocable to the Bank; and
(ii) the amount of any deferred gain or loss allocable to Paradigm and it
Subsidiaries arising out of any Deferred Intercompany Transaction.

            (h)    The unpaid Taxes of Paradigm and its Subsidiaries (i) did

deferred Taxes) as adjusted for the passage of time through the Closing Date in
accordance with the past custom and practice of Paradigm in filing its Tax
Returns.

            (i)    Except as set forth in Schedule 3.10(i), neither Paradigm nor

evidences of indebtedness in original principal amount in excess of $15,000

binding obligations of the respective obligors named therein in accordance with
their respective terms, (ii) the allowance for loan losses shown on the Paradigm
Financial Statements as of and for the three months ended March 31, 2002, was,
and the allowance for loan losses to be shown on the Paradigm Financial
Statements as of any date subsequent to the execution of this Agreement will be,
as of such dates, in the reasonable judgment of management of Paradigm, adequate
to provide for possible losses, net of recoveries relating to loans previously
charged off, in respect of loans outstanding (including accrued interest
receivable) of Paradigm and other extensions of credit (including letters of
credit or commitments to make loans or extend credit), and (iii) the allowance
for loan losses described in (ii) above has been established in accordance with

borrowing arrangement in violation of any law, regulation or rule applicable to

former employee of Paradigm or any Subsidiary.

          (d)     There is no contract, agreement, plan or arrangement covering
any employee or former employee of Paradigm or any of its Affiliates that,
individually or in the aggregate, could give rise to the payment by Paradigm or
any of its Subsidiaries of any amount that would not be deductible pursuant to
the terms of Section 162(m) or Section 280G of the

                                      A-23



Code. Except as required by the continuation coverage requirements of Section
601 et seq. of ERISA and Section 4980B of the Code, neither Paradigm nor any of

with the Community Reinvestment Act (12 U.S.C. (S) 2901 et seq.) and all
regulations promulgated thereunder ("CRA"). The Bank has a rating of
"satisfactory" as of its most recent CRA compliance examination and, knows of no
reason why it would not receive a rating of "satisfactory" or better pursuant to
its next CRA compliance examination or why the FDIC, Banking Department or any
other governmental entity may seek to restrain, delay or prohibit the
transactions contemplated hereby as a result of any act or omission of the Bank
under the CRA.

     Section 3.22 Accounting Controls. Paradigm has devised and maintained a
system of internal accounting controls sufficient to provide reasonable
assurances that: (i) all material transactions are executed in accordance with
general or specific authorization of the Board of Directors and the duly

recorded as necessary to permit the preparation of financial statements in
conformity with GAAP consistently applied with respect to institutions such as
Paradigm or other criteria applicable to such financial statements, and to

properties and assets of Paradigm is permitted only in accordance with general

thereof).

pledges, set off rights, escrow limitations and similar actions taken in the
ordinary course of business).

Paradigm has filed all material reports and statements, together with any
amendments required to be made with respect thereto, that it was required to
file with the SEC pursuant to the Securities Exchange Act of 1934, as amended
(the "Exchange Act"). As of their respective dates, each of such reports and
statements, (or if amended, as of the date so amended), were true and correct
and complied in all material respects with the relevant statutes, rules and
regulations enforced or promulgated by the SEC and such reports did not contain
any untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading.

indebted to Paradigm or any Subsidiary except for (i) normal business expense
advances and (ii) loans that have been entered into in the ordinary course of

shall be, than if the loan had been entered into on an arm's length basis
pursuant to normal commercial terms and conditions and in compliance with
applicable law; (c) neither Paradigm nor any Subsidiary is indebted to any such
person except for amounts due under normal salary or reimbursement or ordinary
business expenses; and (d) no such person is a party to an agreement (other than
a plan or agreement already disclosed in a Schedule to this Agreement) with

Preferred Issue, Paradigm hereby represents, warrants and agrees as follows:

                                      A-25



          (a)  All representations and warranties as made by Paradigm in the

with the applicable legal requirements in all material respects.

          (b)  Paradigm shall upon execution hereof notify First Union, or any
successor trustee named for purposes of the Trust Preferred Issue, of the
execution of this Agreement and shall use every reasonable effort to obtain from
such trustee confirmation that (i) no Default or Event of Default (as those
terms are defined in the Indenture and the Trust Preferred Securities Guarantee
Agreement dated February 20, 2001) exists or is continuing; (ii) no Default or
Event of Default will occur as a result of the execution, delivery and
performance by Paradigm of its obligations under the terms of this Agreement;

          (c)  Paradigm has filed prior to the date hereof, and will continue to
file between the date hereof and the Closing, all required reports, information
and documents which Paradigm is required to file with the trustees or any other
person under the terms of the documents related to the Trust Preferred Issue.

     Section 3.28  Intellectual Property Rights. Schedule 3.28 will contain a
correct and complete list of all registered trademarks, registered service

copyrights presently owned or held by Paradigm or any Subsidiary or used under

Paradigm or its Subsidiaries own or have the right to use and continue to use
the Intellectual Property in the operation of their business. Except as set
forth in Schedule 3.28, neither Paradigm nor any Subsidiary is infringing or
violating any patent, copyright, trademark, service mark, label filing or trade
name owned or otherwise held by any other party, nor has Paradigm or any
Subsidiary used any confidential information or any trade secrets owned or
otherwise held by any other party, without holding a valid license for such use.

     To Paradigm's knowledge, neither Paradigm or any Subsidiary is engaging,
nor has any been charged with engaging, in any kind of unfair or unlawful
competition. Neither the execution, delivery and performance of this Agreement
nor the consummation of the transactions contemplated hereby will in any way
impair the right of Paradigm or any Subsidiary or the Continuing Company to use,
sell, license or dispose of, or to bring any action for the infringement of, the
Intellectual Property.

                IV. REPRESENTATIONS AND WARRANTIES OF PROSPERITY

          (b)  The Board of Directors of Prosperity has duly and validly
approved this Agreement and the transactions contemplated herein and no further
corporate proceedings of Prosperity are needed to execute and deliver this
Agreement and consummate the Merger. This Agreement has been duly executed and
delivered by Prosperity and is a duly authorized, valid, legally binding
agreement of Prosperity enforceable against Prosperity in accordance with its
terms, subject to the effect of bankruptcy, insolvency, reorganization,
moratorium or other similar laws relating to creditors' rights generally and
general equitable principles.

     Section 4.4  No Conflict With Other Instruments. The execution, delivery
and performance of this Agreement or the consummation of the transactions
contemplated hereby will not (i) violate any provision of the Articles of
Incorporation or Bylaws of Prosperity or (ii) assuming all required shareholder

statute, code, ordinance, rule, regulation, judgment, order, writ, decree or
injunction applicable to Prosperity or any of its properties or assets, or (B)

termination or cancellation under, accelerate the performance required by, cause
Prosperity to become subject to or liable for the payment of any tax, or result

                                      A-28



     Prosperity, threatened before any court or administrative body in any
manner against Prosperity or any of its Subsidiaries, or any of their respective
properties or capital stock, which is reasonably likely to have a Material
Adverse Effect on the Condition of Prosperity or the transactions proposed by
this Agreement. To Prosperity's knowledge, there is no basis on which any
litigation or proceeding could be brought which could have a Material Adverse
Effect on the Condition of Prosperity or which would be reasonably likely to
question the validity of any action taken or to be taken in connection with this
Agreement and the transactions contemplated hereby. Prosperity is not in default
with respect to any judgment, order, writ, injunction, decree, award, rule or
regulation of any court, arbitrator or governmental agency or instrumentality.

     Section 4.6  Brokers and Finders. Except as set forth in Schedule 4.6,
neither Purchaser nor any of its officers, directors or employees have employed
any broker or finder or incurred any liability for any brokerage fees,
commissions or finders' fees in connection with this Agreement.

     Section 4.7  Financial Statements.

          (a)  Prosperity has furnished or made available to Paradigm true and
complete copies of its (i) Annual Report on Form 10-K for the year ended
December 31, 2001 ("Annual Report"), as filed with the SEC, which contains
Prosperity's audited balance sheet as of December 31, 2001 and 2000, and the
related statements of income and statements of changes in shareholders' equity
and cash flow for the years ended December 31, 2001, 2000 and 1999 and (ii) its
unaudited balance sheets and related statements of income and statements of
changes in shareholders' equity and cash flows as of and for the three months
ended March 31, 2002 and 2001. The financial statements referred to above
included in the Annual Report and the unaudited financial statements are
collectively referred to herein as the "Prosperity Financial Statements."

          (b)  The Prosperity Financial Statements fairly present the financial
position and results of operation of Prosperity at the dates and for the periods
indicated in conformity with GAAP applied on a consistent basis.

          (c)  Since December 31, 2001, Prosperity has not had any obligations
or liabilities, fixed or contingent, which are material and are not fully shown
or provided for in the Prosperity Financial Statements or otherwise disclosed in
this Agreement, or in any of the documents delivered to Paradigm. Since December
31, 2001, there have been no material changes in the financial condition,
assets, liabilities or business of Prosperity, other than changes in the
ordinary course of business, which individually or in the aggregate have not had
a Material Adverse Effect on the Condition of Prosperity.

     Section 4.8  Securities and Exchange Commission Reporting Obligations.
Since January 1, 1999, Prosperity has filed all material reports and statements,
together with any amendments required to be made with respect thereto, that it
was required to file with the SEC pursuant to the Securities Exchange Act of
1934, as amended (the "Exchange Act"). As of their respective dates, each of
such reports and statements, (or if amended, as of the date so amended), were
true and correct and complied in all material respects with the relevant
statutes, rules and regulations enforced or promulgated by the SEC and such
reports did not contain any untrue

                                      A-29



statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading.

     Section 4.9  Prosperity Employee Benefit Plans. The employee pension
benefits plans and welfare benefit plans (referred to collectively herein as the
"Prosperity Plans") in effect at Prosperity and its Subsidiaries have all been
operated in all material respects in compliance with ERISA, since ERISA became
applicable with respect thereto. None of the Prosperity Plans nor any of their
respective related trusts have been terminated (except the termination of any
Prosperity Plan which is in compliance with the requirements of ERISA and which
will not result in any additional liability to Prosperity), and there has been
no "reportable event," as that term is defined in Section 4043 of ERISA,
required to be reported since the effective date of ERISA which has not been
reported, and none of such Prosperity Plans nor their respective related trusts
have incurred any "accumulated funding deficiency," as such term is defined in
Section 302 of ERISA (whether or not waived), since the effective date of ERISA.
The Prosperity Plans are the only employee pension benefit plans covering
employees of Prosperity and its Subsidiaries. Prosperity and its Subsidiaries
will not have any material liabilities with respect to employee pension
benefits, whether vested or unvested as of the Closing Date, for any of their
employees other than under the Prosperity Plans, and as of the date hereof the
actuarial present value of Prosperity Plan assets of each Prosperity Plan is not
less (and as of the Effective Time of the Merger such present value will not be
less) than the present value of all benefits payable or to be payable
thereunder.

     Section 4.10 Regulatory Approvals. Prosperity has no reason to believe that
it will not be able to obtain all requisite regulatory approvals necessary to
consummate the transactions set forth in this Agreement.

     Section 4.11 Taxes. Prosperity and its Subsidiaries have filed with the
appropriate federal, state and local governmental authorities all material Tax
Returns and reports required to be filed, and have paid all Taxes and
assessments shown to be due and payable thereon. At the time of filing, all such
Tax Returns were correct in all material respects. Neither Prosperity nor any of
its Subsidiaries has executed or filed with the Internal Revenue Service any
agreement extending the period for assessment and collection of any federal
income Tax. None of Prosperity, or any Subsidiary is a party to any pending
action or proceeding by any governmental authority for assessment or collection
of Taxes, nor has any written claim for assessment or collection of Taxes been
asserted against Prosperity or any Subsidiary. All Taxes which Prosperity or any
Subsidiary is or was required by law to withhold or to collect have been duly
withheld and collected and have been paid over to the proper authorities to the
extent due and payable, or segregated and set aside for such payment and, if so
segregated and set aside will be so paid by Prosperity or any Subsidiary, as
required by applicable law.

     Section 4.12 Insurance. Prosperity currently maintains insurance in amounts
reasonably necessary for its operations. In the judgment of the Board of
Directors of Prosperity, such insurance policies in respect of amounts, types
and risks insured are adequate to insure against risks to which Prosperity and
its assets are normally exposed in the operation of its business, subject to
customary deductibles and policy limits. Prosperity has no reason to believe
that existing insurance coverage cannot be renewed as and when the same shall
expire upon terms and conditions as favorable as those presently in effect,
other than possible increases in

                                      A-30



premiums or unavailability of coverage that do not result from any extraordinary

prohibit the transactions contemplated hereby as a result of any act or omission
of the PRSP Bank under the CRA.

Prosperity full access upon reasonable notice to Paradigm's properties, books
and records and other documents and data in order that Prosperity may have full
opportunity to make such reasonable investigation as it shall desire to make of
the affairs of Paradigm, and (ii) furnish Prosperity with such additional
financial and operating data and other information as to its business and
properties as Prosperity shall, from time to time, reasonably request. As soon
as practicable after they become available, Paradigm will deliver or make
available to Prosperity all unaudited quarterly financial statements prepared
for the internal use of management of Paradigm and all Call Reports filed by the
Bank with the appropriate federal regulatory authority after the date of this
Agreement. All such financial statements shall be prepared in accordance with

                                      A-34



will return to Paradigm all documents and other information obtained pursuant

Agreement.

     Section 5.4  Information for Regulatory Applications and SEC Filings. To
the extent permitted by law, Paradigm will furnish Prosperity with all
information concerning Paradigm required for inclusion in (a) any application,
statement or document to be made or filed by Prosperity or any Subsidiary with
any federal or state regulatory or supervisory authority in connection with the
transactions contemplated by this Agreement during the pendency of this
Agreement and (b) any filings with the SEC, including a Registration Statement
on Form S-4, and any applicable state securities authorities and (c) any proxy

Paradigm agrees at any time, upon the request of Prosperity, to furnish to
Prosperity a written letter or statement confirming the accuracy of the
information with respect to Paradigm contained in any report or other
application or statement referred to in Sections 5.1(b) or 5.4 of this
Agreement, and confirming that the information with respect to Paradigm

therein or, if such is not the case, indicating the inaccuracies contained in
such document or indicating the information not furnished by Paradigm expressly
for use therein.

     Section 5.5  Attendance at Certain Paradigm Meetings. In order to
facilitate the continuing interaction of Prosperity with Paradigm, and in order
to keep Prosperity fully advised of all ongoing activities of Paradigm, subject
to the limitation in this Section 5.5, Paradigm agrees and shall cause its
Subsidiaries to agree to allow Prosperity to designate two representatives (who
shall be officers of Prosperity Bank), each of whom will be allowed to attend as
an invited guest and fully monitor all regular and called meetings of the board
of directors and loan and discount and asset liability management committees of
Paradigm and each of its Subsidiaries (including, but not limited to, meetings
of the officers' loan committee of the Bank). Paradigm shall promptly give
Prosperity prior notice by telephone of all called meetings. Such representative
shall have no right to vote and may be excluded from sessions of the board of
directors or loan or investment committee during which there is being discussed
(a) matters involving this Agreement, (b) information or material which Paradigm
or any of its Subsidiaries is required or obligated to maintain as confidential
under applicable laws or regulations or other legal agreements, or (c) pending
or threatened litigation or investigations if, in the opinion of counsel to
Paradigm, the presence of such representative would or might adversely affect
the confidential nature of or any privilege relating to any matters to be
discussed. No attendance by representatives of Prosperity at board meetings
under this Section 5.5 or knowledge gained or deemed to have been gained by
virtue of such attendance will affect any of the representations and warranties
of Paradigm made in this Agreement. If the transactions contemplated by this
Agreement are disapproved by any regulatory authority whose approval is required
or the Agreement is otherwise terminated prior to the Effective Time, then
Prosperity's designees will no longer be entitled to notice of and permission to
attend such meetings.

     Section 5.6  No Solicitation.

                                      A-35



          (a)  So long as this Agreement is in effect, neither Paradigm nor any
Subsidiary nor any of their respective directors or officers shall initiate,
solicit, encourage or otherwise facilitate any inquiries, provide any
information to or negotiate with any other party any proposal or offer that
constitutes, or may reasonably be expected to lead to an Acquisition Proposal,
or (ii) enter into or maintain or continue discussions or negotiate with any
person in furtherance of such inquiries or to obtain an Acquisition Proposal, or
(iii) agree to, approve, recommend, or endorse any Acquisition Proposal, or
authorize or permit any of its or their directors or officers to take any such
action and Paradigm shall notify Prosperity orally (within one business day) and
in writing (as promptly as practicable) of any such inquiries and proposals
received by Paradigm or any Subsidiary or any of their respective directors or
officers, relating to any of such matters; provided, however, that nothing
contained in this Agreement shall prohibit the Board of Directors of Paradigm
from (A) furnishing information to, or engaging in discussions or negotiations
with, any person in response to an unsolicited bona fide written Acquisition
Proposal; or (B) recommending such an unsolicited bona fide written Acquisition
Proposal to the shareholders of Paradigm, if and only to the extent that (w) the
Board of Directors of Paradigm concludes in good faith (after consultation with
its financial advisors) that such Acquisition Proposal would constitute a
Superior Proposal (as defined below), and (x) the Board of Directors of Paradigm
determines in good faith (after consultation with outside legal counsel) that
the failure to take such action would result in a breach by the Board of
Directors of Paradigm of its fiduciary duties to Paradigm's shareholders under
applicable laws, and (y) prior to furnishing such information to, or entering
into discussions or negotiations with, such person Paradigm provides prompt
written notice to Prosperity to the effect that it is furnishing information to,
or entering into discussions or negotiations with, such person (which notice
shall identify the nature and material terms of the proposal), and (z) prior to
providing any information or data to any person in connection with an
Acquisition Proposal by any such person, the Board of Directors of Paradigm
receives from such person an executed confidentiality agreement. Subject to the
requirements of any applicable law, Paradigm agrees to keep Prosperity fully and
timely informed of the status of any discussions, negotiations, furnishing of
non-public information, or other activities relating to an Acquisition Proposal.

          (b)  For purposes of this Agreement, "Acquisition Proposal" means a
written offer or proposal which contains a fixed price per share or a
mathematically ascertainable formula for calculating a price per share for the
Paradigm Common Stock regarding any of the following (other than the
transactions contemplated by this Agreement) involving Paradigm or any
Subsidiary: (i) any merger, reorganization, consolidation, share exchange,
recapitalization, business combination, liquidation, dissolution or other
similar transaction involving any sale, lease, exchange, mortgage, pledge,
transfer or other disposition of, all or any significant portion of the assets
or equity securities or deposits of, Paradigm or any Subsidiary, in a single
transaction or series of related transactions which could reasonably be expected
to impede, interfere with, prevent or materially delay the completion of the
Merger; (ii) any tender offer or exchange offer for 50% or more of the
outstanding shares of capital stock of Paradigm or the filing of a registration
statement under the Securities Act in connection therewith; or (iii) any public
announcement of a proposal, plan or intention to do any of the foregoing or any
agreement to engage in any of the foregoing.

          (c)  For purposes of this Agreement, "Superior Proposal" means a bona
fide Acquisition Proposal made by a third person that the Board of Directors of
Paradigm determines

                                      A-36



in its good faith judgment to be more favorable to Paradigm's shareholders than
the Merger (taking into account, in good faith, the written opinion, with only
customary qualifications, of Paradigm's independent financial advisor that the
value of the consideration to Paradigm's shareholders provided for in such
proposal exceeds the value of the consideration to Paradigm's shareholders
provided for in the Merger) and for which financing, to the extent required, is
then committed or which, in the good faith judgment of the Board of Directors of
Paradigm (taking into account, in good faith, the written advice of Paradigm's
independent financial advisor), is reasonably capable of being obtained by such
third person.

          (d)  Nothing contained in this Section 5.6 shall prohibit Paradigm
from making any disclosure to Paradigm's shareholders which, in the good faith
judgment of the Board of Directors of Paradigm taking into account, in good
faith, the advice of outside counsel, is required under applicable law; provided
that Paradigm does not withdraw or modify, or propose to withdraw or modify, its
position with respect to the Merger or approve or recommend, or propose to
approve or recommend, an Acquisition Proposal unless Paradigm and its Board of
Directors has complied with all provisions of this Section 5.6.

     Section 5.7  Termination Fee. To compensate Prosperity for entering into
this Agreement, taking actions to consummate the transactions contemplated
hereunder and incurring the costs and expenses related thereto and other losses
and expenses, including foregoing the pursuit of other opportunities by
Prosperity, Paradigm and Prosperity agree as follows:

          (a)  Provided that Prosperity shall not be in material breach of its
obligations under this Agreement (which breach has not been cured promptly
following receipt of written notice thereof by Paradigm specifying in reasonable
detail the basis of such alleged breach), Paradigm shall pay to Prosperity the
sum of $2,500,000 (the "Termination Fee") if this Agreement is terminated (i) by
Paradigm under the provisions of Section 9.1(g), (ii) by either Prosperity or
Paradigm under the provisions of Section 9.1(e) due to the failure of Paradigm's
shareholders to approve and adopt this Agreement and the Merger, if at the time
of such failure to so approve and adopt this Agreement and the Merger there
shall exist an Acquisition Proposal with respect to Paradigm and, within nine
months of the termination of this Agreement, Paradigm enters into a definitive
agreement with any third party with respect to any Acquisition Proposal with
respect to Paradigm or (iii) by Prosperity under the provisions of Section
9.1(h).

          (b)  Any payment required by paragraph (a) of this Section 5.7 shall
become payable within two (2) business days after termination of this Agreement.

          (c)  Paradigm acknowledges that the agreements contained in this
Section 5.7 are an integral part of the transactions contemplated in this
Agreement, and that, without these agreements, Prosperity would not enter into
this Agreement; accordingly, if Paradigm fails to promptly pay the Termination
Fee when due, Paradigm shall in addition thereto pay to Prosperity all costs and
expenses (including fees and disbursements of counsel) incurred in collecting
such Termination Fee together with interest on the amount of the Termination Fee
(or any unpaid portion thereof) from the date such payment was required to be
made until the date such payment is received by Prosperity at the prime rate as
reported in The Wall Street Journal as in effect from time to time during such
period.

                                      A-37



     Section 5.8  Voting Agreement. Paradigm acknowledges that the directors and
10% or greater shareholders of Paradigm as of the date hereof have agreed to
vote their shares of Paradigm Common Stock in favor of this Agreement and the
transactions contemplated hereby, subject to required regulatory approvals,
pursuant to a Voting Agreement substantially in the form of Exhibit E to this
Agreement which has been executed as of the date of this Agreement.

     Section 5.9  Termination of Data Processing Contracts. Paradigm will timely
take any and all actions necessary, including but not limited to notifying
appropriate parties, to ensure that its current data processing contracts will
if the Merger occurs, be terminated.

     Section 5.10 Affiliates' Letters. No later than the fifteenth (15/th/) day
following the date of execution of this Agreement, Paradigm shall deliver to
Prosperity, after consultation with legal counsel, a list of names and addresses
of those persons who are then "affiliates" of Paradigm with respect to the
Merger within the meaning of Rule 144 under the Securities Act. There shall be
added to such list the names and addresses of any other person (within the
meaning of Rule 144) which Prosperity identifies (by written notice to Paradigm
within three business days after receipt of such list) as possibly being a
person who may be deemed to be an "affiliate" of Paradigm within the meaning of
Rule 144. Paradigm shall cause each person identified as an "affiliate" to
deliver, to Prosperity, not later than the thirtieth (30th) day following the
date of execution of this Agreement, an agreement dated as of the date of
delivery thereof in the form of Exhibit F attached hereto.

     Section 5.11 Assumption of Paradigm Stock Options. Paradigm will use its
best efforts to cause each of the holders of Paradigm Stock Options as of the
Execution Date to execute and deliver to Prosperity, at least ten (10) days
prior to the Closing Date, an acknowledgment that such holder's Paradigm Stock
Option shall be converted, in accordance with its terms, into an option to
purchase a number of shares of Prosperity Common Stock equal to the number of
shares of Paradigm Common Stock subject to the original option multiplied by the
Total Exchange Ratio or, if applicable, the Adjusted Total Exchange Ratio, at an
exercise price per share equal to the exercise price per share of the original
option divided by the Total Exchange Ratio or, if applicable, the Adjusted Total
Exchange Ratio, consistent with the provisions of Section 2.3 hereof.

     Section 5.12 Conforming Accounting Adjustments. Paradigm shall, if
requested by Prosperity, consistent with GAAP, immediately prior to Closing,
make such accounting entries as Prosperity may reasonably request in order to
conform the accounting records of Paradigm to the accounting policies and
practices of Prosperity. No such adjustment shall of itself constitute or be
deemed to be a breach, violation or failure to satisfy any representation,
warranty, covenant, condition or other provision or constitute grounds for
termination of this Agreement or be an acknowledgment by Paradigm (i) of any
adverse circumstances for purposes of determining whether the conditions to
Prosperity's obligations under this Agreement have been satisfied, or (ii) that
such adjustment is required for purposes of determining satisfaction of the
condition to Prosperity's obligations under this Agreement set forth in Section
10.3 hereof or (iii) that such adjustment has any bearing on the number of
shares of Prosperity Common Stock issuable hereunder. No adjustment required by
Prosperity shall (a) require any prior filing with any governmental agency or
regulatory authority or (b) violate any law, rule or regulation applicable to
Paradigm.

                                      A-38

     Section 5.14 Trust Preferred Securities. Prosperity shall have received
evidence that all notices required to be given and any consents required to be
obtained pursuant to any document or instrument related to the Trust Preferred
Issue have in fact been given or obtained by Paradigm. Prosperity shall have
received the confirmation referred to in Section 3.27 hereof.

     Section 5.15 Environmental Investigation; Rights to Terminate Agreement.

          (a)  Prosperity and its consultants, agents and representatives shall
have the right to the same extent that Paradigm or its Subsidiaries has such
right, but not the obligation or responsibility, to inspect any property,
including, without limitation, conducting asbestos surveys and sampling,
environmental assessments and investigation, and other non-invasive or
non-destructive environmental surveys and analyses including soil and ground
sampling ("Environmental Inspections") at any time on or prior to thirty (30)
days after the date of this Agreement. If, as a result of any such Environmental
Inspection, further investigation ("secondary investigation") including, without
limitation, test borings, soil, water, asbestos or other sampling, is deemed
desirable by Prosperity, Prosperity shall (i) notify Paradigm of any property
for which it intends to conduct such a secondary investigation and the reasons
for such secondary investigation, and (ii) conclude such secondary
investigation, on or prior to sixty (60) days after the date of this Agreement.
Prosperity shall give reasonable notice to Paradigm of such secondary
investigations, and Paradigm may place reasonable time and place restrictions on
such secondary investigations.

          (b)  Paradigm agrees to indemnify and hold harmless Prosperity for any
claims for damage to property, or injury or death to persons, made as a result
of any Environmental Inspection or secondary investigation conducted by
Prosperity or its agents, or to the extent such damage or injury is attributable
to the negligent actions or negligent omissions of Paradigm or their respective
agents. Prosperity agrees to indemnify and hold harmless Paradigm for any claims
for damage to property, or injury or death to persons, to the extent
attributable to the negligent actions or omissions of Prosperity or its agents
in performing any Environmental Inspection or secondary investigation.
Prosperity shall not have any liability or responsibility of any nature
whatsoever for the results, conclusions or other findings related to any
Environmental Inspection, secondary investigation or other environmental survey.
If this Agreement is terminated, then except as otherwise required by law,
reports to any governmental authority of the results of any Environmental
Inspection, secondary investigation or other environmental survey shall be made
by Paradigm and not by Prosperity. Prosperity shall make no such report prior to
Closing unless required to do so by law, and in such case will give Paradigm
reasonable prior notice of Prosperity's intentions.

          (c)  Prosperity shall have the right to terminate this Agreement
within ninety (90) days after the date of this Agreement if (i) the results of
such Environmental Inspection, secondary investigation or other environmental
survey are disapproved by Prosperity because the

                                      A-39



Environmental Inspection, secondary investigation or other environmental survey
identifies violations or potential violations of Environmental Laws that would
have or are reasonably likely to have a Material Adverse Effect on the Condition
of Paradigm; (ii) any past or present event, condition or circumstance that
would require remedial or cleanup action under Environmental Laws involving an
expenditure in excess of $500,000 or having a Material Adverse Effect on the
Condition of Paradigm; (iii) the Environmental Inspection, secondary
investigation or other environmental survey identifies the presence of any
underground or above ground storage tank in, on or under any property that is
not shown to be in compliance with all Environmental Laws applicable to the tank
either now or at a future time certain, or that has had a release of petroleum
or some other Hazardous Material that has not been cleaned up to the
satisfaction of the relevant governmental authority or any other party with a
legal right to compel cleanup; or (iv) the Environmental Inspection, secondary
investigation or other environmental survey identifies the presence of any
asbestos-containing material in, on or under any property, the removal of which
would have a Material Adverse Effect on the Condition of Paradigm.

                (d) Paradigm agrees to make available upon request to Prosperity
and its consultants, agents and representatives all documents and other material
relating to environmental conditions of any property including, without
limitation, the results of other environmental inspections and surveys to the
extent such documents are in the actual possession of Paradigm. Paradigm also
agrees that all engineers and consultants who prepared or furnished such reports
may discuss such reports and information with Prosperity and, at Prosperity's
cost, shall be entitled to certify the same in favor of Prosperity and its
consultants, agents and representatives and make all other data available to
Prosperity and its consultants, agents and representatives.

                          VI. COVENANTS OF PROSPERITY

     Prosperity covenants and agrees with Paradigm as follows:

     Section 6.1    Best Efforts. Prosperity will take all reasonable action to
aid and assist in the consummation of this Agreement and the transactions
contemplated hereby, and will use its best efforts to take or cause to be taken
all other actions necessary, proper or advisable to consummate the transactions
contemplated by this Agreement, including such actions which are necessary,
proper or advisable in connection with filing applications with, or obtaining
approvals from, all regulatory authorities having jurisdiction over the
transactions contemplated by this Agreement.

     Section 6.2    Information for Regulatory Applications and Proxy
Solicitation. To the extent permitted by law, Prosperity will furnish Paradigm
with all information concerning Prosperity required for inclusion in (a) any
application, statement or document to be made or filed by Paradigm with any
federal or state regulatory or supervisory authority in connection with the
transactions contemplated by this Agreement during the pendency of this
Agreement and (b) any proxy materials to be furnished to the shareholders of
Paradigm in connection with their consideration of the Merger. Prosperity
represents and warrants that all information so furnished for such statements
and applications shall, to the best of its knowledge, be true and correct in all
material respects without omission of any material fact required to be stated to
make the information not misleading. Prosperity agrees, upon the request of
Paradigm, to furnish to

                                      A-40



Paradigm a written letter or statement confirming to the best of its knowledge
the accuracy of the information with respect to Prosperity and its Subsidiaries
contained in any report or other application or statement referred to in
Sections 6.1 or 6.2 of this Agreement, and confirming that the information with
respect to Prosperity contained in such document or draft was furnished
expressly for use therein or, if such is not the case, indicating the
inaccuracies contained in such document or indicating the information not
furnished by Prosperity expressly for use therein.

     Section 6.3    Registration Statement. Within thirty (30) days after the
execution of this Agreement, Prosperity will prepare and file with the SEC a
Registration Statement on Form S-4 under the Securities Act and any other
applicable documents, relating to the shares of Prosperity Common Stock to be
delivered to the shareholders of Paradigm pursuant to this Agreement, and will
use its best efforts to cause the Registration Statement to become effective.
Paradigm and its counsel shall be given the opportunity to participate in the
preparation of the Registration Statement and shall have the right to approve
the content of the Registration Statement with respect to Paradigm and the
Paradigm meeting of shareholders. At the time the Registration Statement becomes
effective, the Registration Statement will comply in all material respects with
the provisions of the Securities Act and the published rules and regulations
thereunder, and will not contain any untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein not false or misleading, and at the time of mailing thereof
to Paradigm's shareholders and at the time of the Paradigm Shareholders' Meeting
held to approve the Merger, the prospectus included as part of the Registration
Statement, as amended or supplemented by any amendment or supplement filed by
Prosperity (the "Proxy Statement/Prospectus"), will not contain any untrue
statement of a material fact or omit to state any material fact necessary to
make the statements therein not false or misleading; provided, however, that
none of the provisions of this subparagraph shall apply to statements in or
omissions from the Registration Statement or the Proxy Statement/Prospectus made
in reliance upon and in conformity with information furnished by Paradigm for
use in the Registration Statement or the Proxy Statement/Prospectus.

     Section 6.4    Nasdaq Listing. Prosperity will file all documents required
to be filed to have the shares of Prosperity Common Stock to be issued pursuant
to the Agreement included for quotation on Nasdaq and use its best efforts to
effect said listing.

     Section 6.5    Rule 144 Compliance. For a period of not less than two years
after the date hereof (or such shorter period of time as may be applicable for
"affiliates" of Paradigm to sell shares of Prosperity Common Stock in accordance
with Rule 145 of the Securities Act), Prosperity shall use its best efforts to
file in a timely manner all reports with the SEC required to be filed by it
pursuant to Section 13 and Section 15(d) of the Exchange Act.

     Section 6.6    Indemnification; Insurance.

                (a) For a period of three (3) years from and after the Effective
Time, Prosperity (the "Indemnifying Party") shall indemnify and hold harmless
each present and former director, officer and employee of Paradigm and its
Subsidiaries determined as of the Effective Time (the "Indemnified Parties")
against any costs or expenses (including reasonable attorneys' fees), judgments,
fines, losses, claims, damages or liabilities (collectively, "Costs") incurred
in connection with any claim, action, suit, proceeding or investigation whether
civil or

                                      A-41



criminal, administrative or investigative, arising out of matters existing or
occurring at or prior to the Effective Time, whether asserted or claimed prior
to, at or after the Effective Time to the fullest extent to which such
Indemnified Parties were entitled under the Paradigm Constituent Documents. The
indemnification provisions currently contained in the Paradigm Constituent
Documents shall not be amended after the date of this Agreement.

                (b) Any Indemnified Party wishing to claim indemnification under
this section, upon learning of any such claim, action, suit, proceeding or
investigation, shall promptly notify the Indemnifying Party, but the failure to
so notify shall not relieve the Indemnifying Party of any liability it may have
to such Indemnified Party if such failure does not materially prejudice the
Indemnifying Party. In the event of any such claim, action, suit, proceeding or
investigation (whether arising before or after the Effective Time), (i) the
Indemnifying Party shall have the right to assume the defense thereof and the
Indemnifying Party shall not be liable to such Indemnified Parties for any legal
expenses of other counsel or any other expenses subsequently incurred by such
Indemnified Parties in connection with the defense thereof, except that if the
Indemnifying Party elects not to assume such defense or counsel for the
Indemnified Party and the Indemnified Parties, the Indemnified Parties may
retain counsel which is reasonably satisfactory to the Indemnifying Party, and
the Indemnifying Party shall pay, promptly as statements therefor are received,
the reasonable fees and expenses of such counsel for the Indemnified Parties
(which may not exceed one firm in any jurisdiction unless the use of one counsel
for such Indemnified Parties would present such counsel with a conflict of
interest), (ii) the Indemnified Parties will cooperate in the defense of any
such matter and (iii) the Indemnifying Party shall not be liable for any
settlement effected without its prior written consent.

                (c) Prosperity shall use its commercially reasonable efforts to
maintain its existing policy of directors and officers liability insurance (or
comparable coverage) for a period of not less than three (3) years after the
Effective Time; which policy shall be amended, however, to include the directors
and officers of Paradigm currently covered under the policy held by Paradigm,
and which shall be a "claims made" policy providing coverage for (among other
things) acts or omissions occurring prior to the Effective Time.

                (d) In the event that Prosperity or any of its respective
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person, then, and in each such case, the successors
and assigns of such entity shall assume the obligations set forth in this
Agreement, which obligations are expressly intended to be for the irrevocable
benefit of, and shall be enforceable by, each director and officer covered
hereby.

     Section 6.7    Access to Properties and Records. To the extent permitted by
applicable laws and any applicable contractual obligations, Prosperity will (i)
afford the executive officers and authorized representatives (including legal
counsel, accountants and consultants) of Paradigm full access upon reasonable
notice to the properties, books and records of Prosperity in order that Paradigm
may have full opportunity to make such reasonable investigation as it shall
desire to make of the affairs of Prosperity, and (ii) furnish Paradigm with such
additional financial and operation data and other information as to the business
and properties of Prosperity

                                      A-42



as Paradigm shall, from time to time, reasonably request. As soon as practicable
after they become available, Prosperity will deliver or make available to
Paradigm all unaudited quarterly financial statements prepared for the internal
use of management of Prosperity and all Call Reports filed by PRSP Bank with the
appropriate federal regulatory authority after the date of this Agreement. All
such financial statements shall be prepared in accordance with GAAP (or
regulatory accounting principles, as applicable) applied on a consistent basis
with previous accounting periods. In the event of the termination of this
Agreement, Paradigm will return to Prosperity all documents and other
information obtained pursuant hereto and will keep confidential any information
obtained pursuant to this Agreement.

     Section 6.8    Assumption of Paradigm Stock Options.

                (a) At the Effective Time, each outstanding and unexercised
Paradigm Stock Option shall be assumed by Prosperity as provided in Section 2.3
hereof.

                (b) Prosperity shall take all corporate action necessary to
reserve for issuance a sufficient number of shares of Prosperity Common Stock
for delivery upon exercise of Paradigm Stock Options assumed by Prosperity in
accordance with Section 2.3. As soon as practicable after the Effective Time,
Prosperity shall file a registration statement on Form S-8 (or any successor or
other appropriate form) with respect to the shares of Prosperity Common Stock
subject to such options and shall use its best efforts to maintain the
effectiveness of the registration statement (and maintain the current status of
the prospectus contained therein) for so long as such options remain
outstanding. With respect to those individuals who subsequent to the Merger will
be subject to the reporting requirements under Section 16(a) of the Exchange
Act, where applicable, Prosperity shall administer the Paradigm Stock Option
Plan in a manner that complies with Rule 16b-3 promulgated under the Exchange
Act to the extent the Paradigm Stock Option Plan complied with such rule prior
to the Merger.

     Section 6.9    Supplemental Indenture. Prosperity agrees that at or prior
to the Effective Time it will enter into a supplemental indenture to the
Indenture dated February 20, 2001 by and between Paradigm and First Union, as
trustee (the "Indenture"), assuming the obligations and performance of the
covenants of Paradigm under the Indenture at the Effective Time in accordance
with Section 12.1 of the Indenture.

     Section 6.10   Appointment of Directors.

                (a) Prosperity agrees, at the Effective Time, to take all
actions necessary to (i) increase by two (2) the number of positions on the
Prosperity Board of Directors and (ii) cause each of William H. Fagan, MD and
Charles J. Howard, MD to be elected or appointed as a director of Prosperity at
the Effective Time, if each is still a member of the Paradigm Board of Directors
immediately prior to the Effective Time and if each is willing and eligible to
serve as a director of Prosperity.

                (b) Prosperity agrees, at the Effective Time, to take all
actions necessary to (i) increase by two (2) the number of positions on the PRSP
Bank Board of Directors and (ii) cause each of Peter E. Fisher and Leah
Huffmeister to be elected or appointed as a director of PRSP Bank at the
Effective Time, if each is still a member of the Paradigm Bank Board of
Directors

                                      A-43



immediately prior to the Effective Time and if each is willing and eligible to
serve as a director of PRSP Bank. Prosperity agrees to appoint Mr. Fisher to
serve as Vice Chairman of the Board of Directors of PRSP Bank.

     Section 6.11   Regulatory and Other Approvals. Prosperity shall promptly,
but in no event later than forty-five (45) days after the date of this
Agreement, file or cause to be filed applications for all regulatory approvals
required to be obtained by Prosperity, Delaware Company or PRSP Bank in
connection with this Agreement and the other agreements contemplated hereby.
Prosperity shall promptly furnish Paradigm with copies of all such regulatory
filings and all correspondence for which confidential treatment has not been
requested. Prosperity shall use its best efforts to obtain all such regulatory
approvals and any other approvals from third parties, at the earliest
practicable time.

                VII. MUTUAL COVENANTS OF PARADIGM AND PROSPERITY

     Section 7.1    Notification; Updated Disclosure Schedules. Paradigm shall
give prompt notice to Prosperity, and Prosperity shall give prompt notice to the
Paradigm, of (i) any representation or warranty made by it in this Agreement
becoming untrue or inaccurate in any material respect, including, without
limitation, as a result of any change in a Schedule, or (ii) the failure by it
to comply with or satisfy in any material respect any covenant, condition or
agreement to be complied with or satisfied by it under this Agreement; provided,
however, that no such notification shall affect the representations, warranties,
covenants or agreements of the parties or the conditions to the obligations of
the parties under this Agreement.

     Section 7.2    Employee Benefit Plans. Paradigm shall execute and deliver
such instruments and take such other actions as Prosperity may reasonably
require in order to cause the amendment or termination of any employee benefit
plan of Paradigm or any of its Subsidiaries on terms satisfactory to Prosperity
and in accordance with applicable law and effective as of the Closing Date.
Prosperity agrees that the employees of Paradigm and its Subsidiaries who
continue their employment after the Closing Date (the "PBT Employees") will be
entitled to participate as newly hired employees in the employee benefit plans
and programs maintained for employees of Prosperity and its Subsidiaries, in
accordance with the respective terms of such plans and programs, and Prosperity
shall take all actions necessary or appropriate to facilitate coverage of the
PBT Employees in such plans and programs from and after the Closing Date,
subject to the following:

                (a) Each PBT Employee will be entitled to credit for prior
service with the Bank for all purposes under the employee welfare benefit plans
and other employee benefit plans and programs (other than stock option plans),
sponsored by Prosperity and PRSP Bank to the extent Paradigm or the Bank
sponsored a similar type of plan in which the PBT Employees participated
immediately prior to the Closing Date. Any eligibility waiting period and
pre-existing condition exclusion applicable to such plans and programs shall be
waived with respect to each PBT Employee and their eligible dependents. For
purposes of determining PBT Employee's benefit for the calendar year in which
the Merger occurs under Prosperity's vacation program, any vacation taken by the
PBT Employee immediately preceding the Effective Time for the calendar year in
which the Merger occurs will be deducted from the total Prosperity vacation
benefit available to such PBT Employee for such calendar year. Prosperity
further

                                      A-44



agrees to credit each PBT Employee and their eligible dependents for the year
during which coverage under Prosperity's group health plan begins, with any
deductibles already incurred during such year, under Paradigm's group health
plan.

               (b) Each PBT Employee shall be entitled to credit for past
service with the Bank for the purpose of satisfying any eligibility or vesting
periods applicable to Prosperity's employee benefit plans which are subject to
Sections 401(a) and 501(a) of the Code (including, without limitation,
Prosperity's 401(k) Profit Sharing Plan).

     Section 7.3   Confidentiality. Neither Prosperity nor Paradigm will,
directly or indirectly, before or after the consummation or termination of this
Agreement, disclose any confidential information, whether written or oral
("Subject Information") acquired from the other party to any person, firm,
corporation, association or other entity for any reason or purpose whatsoever,
other than in connection with the regulatory notice and application process or,
after termination of this Agreement pursuant to Section 9.1 hereof, use such
Subject Information for its own purposes or for the benefit of any person, firm,
corporation, association, or other entity under any circumstances. The term
"Subject Information" does not include any information that (i) at the time of
disclosure or thereafter is generally available to and known to the public,
other than by a breach of this Agreement by the disclosing party, (ii) was
available to the disclosing party on a nonconfidential basis from a source other
than the nondisclosing party or (iii) was independently acquired or developed
without violating any obligations of this Agreement.

     Section 7.4   Publicity. Except as otherwise required by applicable law or
the rules of the Nasdaq, as long as this Agreement is in effect, neither
Prosperity nor Paradigm shall, nor shall they permit any of their respective
Subsidiaries and Affiliates to, issue or cause the publication of any press
release or other public announcement with respect to, or otherwise make any
public statement concerning, the transactions contemplated by this Agreement
without the consent of the other party, which consent shall not be unreasonably
withheld or delayed; provided, however, that this shall not include notices
required to be published pursuant to the regulatory application process. The
parties agree that they will make a good faith effort to reach agreement
expeditiously on such press releases, announcements or other public statements.

     Section 7.5   Restrictions on Trading in Prosperity Common Stock. Neither
Prosperity, Paradigm, any of their respective Subsidiaries nor any director or
executive officer of Prosperity, Paradigm or their respective Subsidiaries shall
directly or indirectly purchase or sell on the Nasdaq any shares of Prosperity

into or exercisable for shares of Prosperity Common Stock during the fifteen
trading days ending on and including the third trading day preceding the
Effective Time.

                                 VIII. CLOSING

     Section 8.1   Closing. Subject to the other provisions of this Article
VIII, on a mutually acceptable date ("Closing Date") as soon as practicable
within a thirty (30) day period commencing with the latest of the following
dates:

               (a) the receipt of all requisite shareholder approvals and the
last approval from any requisite regulatory or supervisory authority and the
expiration of any statutory or

                                      A-45



regulatory waiting period which is necessary to effect the Merger, the Delaware
Merger and the Bank Merger; or

               (b) if the transactions contemplated by this Agreement are being
contested in any legal proceeding and Prosperity or Paradigm, pursuant to
Section 12.1 herein, have elected to contest the same, then the date that such
proceeding has been brought to a conclusion favorable, in the judgment of each
of Prosperity and Paradigm, to the consummation of the transactions contemplated
herein, or such prior date as each of Prosperity and Paradigm shall elect
whether or not such proceeding has been brought to a conclusion;

     A meeting ("Closing") will take place at which the parties to this
Agreement will exchange certificates, opinions, letters and other documents in
order to determine whether any condition exists which would permit the parties
hereto to terminate this Agreement. If no such condition then exists or if no
party elects to exercise any right it may have to terminate this Agreement, then
and thereupon the appropriate parties shall execute such documents and
instruments as may be necessary or appropriate to effect the transactions
contemplated by this Agreement.

     The Closing shall take place at the offices of Bracewell & Patterson,
L.L.P. in Houston, Texas, or at such other place to which the parties hereto may
mutually agree.

     Section 8.2   Effective Time. Prosperity and Paradigm shall, in accordance
with Section 5.04 of the TBCA, file Articles of Merger with the Secretary of
State of Texas regarding the Merger. The Merger shall become effective as of the
close of business on the date on which such filing has been completed and the
Secretary of State of Texas has issued a Certificate of Merger with respect to
the Merger (the "Effective Time"). The parties hereto shall take all such other
and further actions as may be required by applicable law to make the Merger, the
Delaware Merger and the Bank Merger effective on the same date.

                                IX. TERMINATION

     Section 9.1   Termination. Notwithstanding any other provision of this
Agreement, this Agreement may be terminated and the Merger may be abandoned at
any time prior to the Effective Time:

               (a) by the Board of Directors of Prosperity or Paradigm at any
time prior to the Effective Time if:

                   (i)   any court of competent jurisdiction in the United
States or other United States (federal or state) governmental body shall have
issued an order, decree or ruling or taken any other action restraining,
enjoining or otherwise prohibiting the Merger and such order, decree, ruling or
other action shall have been final and non-appealable;

                   (ii)  any of the transactions contemplated by this Agreement
are disapproved by any regulatory authority or other person whose approval is
required to consummate any of such transactions; or

                                      A-46



                   (iii) the Merger shall not have become effective on or before
November 27, 2002, the two hundred and tenth (210th) day following the date of
this Agreement, or such later date as shall have been approved in writing by the
Boards of Directors of Prosperity and Paradigm; provided, however, that the
right to terminate under this Section 9.1(a)(iii) shall not be available to any
party whose failure to fulfill any material obligation under this Agreement has
been the cause of, or has resulted in, the failure of the Merger to become
effective on or before such date;

               (b) by the Board of Directors of Paradigm if (i) Prosperity shall
fail to comply in any material respect with any of its covenants or agreements
contained in this Agreement, or if any of the representations or warranties of
Prosperity contained herein shall be inaccurate in any material respect or (ii)
any of the conditions set forth in Article XI have not been met or waived by
Paradigm. In the event the Board of Directors of Paradigm desires to terminate
this Agreement because of an alleged breach or inaccuracy as provided in (i)
above, such Board of Directors must notify Prosperity in writing of its intent
to terminate stating the reason therefor. Prosperity shall have fifteen (15)
days from the receipt of such notice to cure the alleged breach or inaccuracy,
subject to the approval of Paradigm (which approval shall not be unreasonably
withheld or delayed);

               (c) by action of the Board of Directors of Prosperity if (i)
Paradigm shall fail to comply in any material respect with any of its covenants
or agreements contained in this Agreement, or if any of the representations or
warranties of Paradigm contained herein shall be inaccurate in any material
respect, (ii) if the conditions set forth in Article X have not been met or
waived by Prosperity or (iii) the Board of Directors of Prosperity reasonably
concludes, after consulting with counsel, that Prosperity will be unable to
obtain any regulatory approval required in order to consummate the Merger, the
Delaware Merger or the Bank Merger or any such approval is accompanied by terms
or conditions which materially and adversely impact the financial consequences
of the Merger, the Delaware Merger or the Bank Merger to Prosperity. In the
event the Board of Directors of Prosperity desires to terminate this Agreement
because of an alleged breach or inaccuracy as provided in (i) above, the Board
of Directors must notify Paradigm in writing of its intent to terminate stating
the cause therefor. Paradigm shall have fifteen (15) days from the receipt of
such notice to cure the alleged breach or inaccuracy, subject to the approval of
Prosperity (which approval shall not be unreasonably withheld or delayed);

               (d) by Paradigm if the average closing bid price of a share of
Prosperity Common Stock on the Nasdaq (as reported by The Wall Street Journal
or, if not reported thereby, another alternative source as chosen by Prosperity)
during the Price Measurement Period is less than $24.41 per share and (ii) the
percentage difference between $32.55 and the Measurement Price is less than 10%
lower than the percentage difference between the closing price of the KBW Bank
Index on April 26, 2002 and the average closing price of the KBW Bank Index
during the Price Measurement Period. To terminate this Agreement pursuant to
this Section 9.1(d), Paradigm must provide to Prosperity written notice of its
intent to terminate within two business days following the end of the Price
Measurement Period ("Termination Notice"). For a period of five business days
from the date of receipt of the Termination Notice, Prosperity shall have the
option, but not the obligation, to increase the aggregate number of shares of
Prosperity Common Stock into which shares of Paradigm Common Stock will be
converted at the Effective Time as set forth in Section 2.2 hereof ("Walkaway
Counter Offer").

                                      A-47



In the event that Prosperity elects to make the Walkaway Counter Offer, the
Termination Notice previously sent by Paradigm shall be null and void and of no
effect, and Paradigm shall no longer have the right to terminate the Agreement
pursuant to this Section 9.1(d). If Prosperity does not elect to make the
Walkaway Counter Offer, this Agreement shall terminate;

               (e) by the Board of Directors of either Paradigm or Prosperity if
the conditions set forth in Article XII have not been met or waived by the other
party;

               (f) by mutual written consent of the Board of Directors of
Prosperity and Paradigm;

               (g) by Paradigm if (i) there shall not have been a breach of any
covenant or agreement on the part of Paradigm or any Subsidiary under this
Agreement and (ii) prior to the Effective Time, Paradigm shall have received a
bona fide Acquisition Proposal and the Paradigm Board of Directors determines in
its good faith judgment and in the exercise of its fiduciary duties, based as to
legal matters on the written opinion of independent legal counsel and as to
financial matters on the written opinion of an investment banking firm of
national reputation, that such alternative Acquisition Proposal (if consummated
pursuant to its terms) is a Superior Proposal and that the failure to terminate
this Agreement and accept such Superior Proposal would be inconsistent with the
proper exercise of such fiduciary duties; provided, however, that termination
under this clause (ii) shall not be deemed effective until payment of the
Termination Fee required by Section 5.7 hereof; and

               (h) by Prosperity if the Paradigm Board of Directors shall have
(i) resolved to accept a Superior Proposal, (ii) recommended to the shareholders
of Paradigm that they tender their shares in a tender or exchange offer
commenced by a third party or (iii) withdrawn or modified, in any manner that is
adverse to Prosperity, its recommendation or approval of this Agreement or the
Merger or recommended to the Paradigm shareholders acceptance or approval of any
alternative Acquisition Proposal, or shall have resolved to the foregoing.

       Section 9.2 Effect of Termination. In the event of abandonment of the
Merger and termination of this Agreement by either Prosperity or Paradigm as
provided under Section 9.1 hereof without breach by any party hereto, this
Agreement shall become void and have no effect, without any liability, except as
specifically contemplated in Section 9.1, on the part of any party or its
directors, officers, agents, representatives or shareholders, except that the
provisions of this Section 9.2, Section 7.3, Section 5.7 and Section 13.4 shall
survive any such termination and abandonment. Nothing contained in this Section
9.2 shall relieve any party of any liability for a breach of this Agreement.

condition of Paradigm or any of its Subsidiaries which, individually or in the
aggregate, has had or is reasonably likely to have, a Material Adverse Effect on
the Condition of Paradigm or the transactions contemplated hereby, nor shall any
event have occurred which, with the lapse of time, will cause or result in a
Material Adverse Effect on the Condition of Paradigm; provided, however, that
such a change for purposes of this Section 10.3, does not include a change with
respect to, or effect on, Paradigm resulting from (i) a change in law, rule,
regulation or GAAP, (ii) as a result of entering into this Agreement or
complying with the terms of this Agreement or (iii) from any other matter

counsel to Paradigm, dated as of the Closing Date, in form and substance
satisfactory to counsel for Prosperity.

     Section 10.5  Tax Opinion. Prosperity shall have received an opinion of
Bracewell & Patterson, L.L.P. to the effect that on the basis of certain facts,
representations and opinions set forth in such opinion that the Merger will

In rendering such opinion, such counsel may require and rely upon and may
incorporate by reference representations and covenants, including those
contained in certificates of officers and/or directors of Prosperity, Paradigm
and others.

     Section 10.6  Releases. Each of the officers (with a title of senior vice

                              W I T N E S S E T H:
                              - - - - - - - - - -

         WHEREAS, Prosperity and Paradigm entered into that certain Agreement
and Plan of Reorganization dated as of May 1, 2002 (the "Merger Agreement"),
pursuant to which Paradigm will be merged with and into Prosperity (the
"Merger") and the holders of the common stock of Paradigm, par value $1.00 per
share (the "Paradigm Common Stock"), shall receive consideration in the form of
shares of common stock of Prosperity, par value $1.00 per share ("Prosperity
Common Stock") and cash in lieu of fractional shares, in accordance with such
Merger Agreement (the "Merger Consideration");

         WHEREAS, Section 2.2 of the Merger Agreement provides for the escrow of
a portion of the shares of Prosperity Common Stock (along with all shares of
Prosperity Common Stock received as a result of a stock split, stock dividends
or other similar transaction and any securities received in exchange for the
Prosperity Common Stock as a result of a merger, stock exchange, sale of
substantially all of the assets of Prosperity or other corporate reorganization)
(collectively, the "Holdback Shares") and cash to be distributed to Beneficial
Owners, and such Holdback Shares and cash shall be distributed either to
Prosperity, to the Beneficial Owners, or to both Prosperity and the Beneficial
Owners as more particularly described herein; and

         WHEREAS, Prosperity, Paradigm and the Escrow Agent believe it is in
their respective best interests and the best interests of the shareholders of
Prosperity and Paradigm to enter into this Escrow Agreement;

         NOW, THEREFORE, in consideration of the premises and covenants
contained herein and in the Merger Agreement, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties, intending to be legally bound, hereby agree as follows:

         1. Definitions. Except as herein defined, capitalized terms used in
            -----------
this Holdback Escrow Agreement have the meanings set forth in the Merger
Agreement.

                                       B-1



         2. Appointment of Escrow Agent. Prosperity Bank is hereby appointed as
            ---------------------------
Escrow Agent under this Holdback Escrow Agreement to perform the services
described herein, and the Escrow Agent hereby accepts such appointment.

         3. Loan Portfolio. Attached hereto as Schedule 2 is a list of certain
            --------------
loans in Paradigm's loan portfolio as of the Closing Date (the "Scheduled
Loans"), setting forth the principal amount and outstanding balance as of the
date of the Merger Agreement. As of the date of the Merger Agreement, the
aggregate outstanding balance of the Scheduled Loans was $1,877,839 and the
aggregate value of the Holdback Shares, based on a price of $16.275 per share,
was $1,225,000 ("Holdback Share Value").

         4. Holdback Shares Deposited into Escrow. Pursuant to the terms of the
            -------------------------------------
Merger Agreement, Prosperity shall deposit or cause to be deposited 75,270
shares of Prosperity Common Stock, subject to adjustment as provided in Section
2.2(c) of the Merger Agreement, into an account maintained by the Escrow Agent
("Escrow Account") on the Closing Date. All Holdback Shares and all dividends
earned on the Holdback Shares, shall remain in the Escrow Account, subject only
to disbursement in accordance with Section 5 of this Escrow Agreement, and such
shares shall not be disbursed in any other manner.

         At all times during which any Holdback Shares are held pursuant to this
Holdback Escrow Agreement, the Beneficial Owners shall be treated as the
beneficial owners of the Holdback Shares and as the beneficial owners of any
dividends thereon and any other proceeds thereof, in each case subject to the
rights of Prosperity under this Holdback Escrow Agreement to require that such
Holdback Shares and dividends thereon be distributed to Prosperity in payment of
Covered Losses (as herein defined) attributable to one or more Scheduled Loans.
The Beneficial Owners shall have no right to substitute other property for the
Holdback Shares. The Shareholder Representative shall be entitled to vote the
allocated Holdback Shares in any action requiring a vote of the shareholders of
Prosperity, until such time as such Holdback Shares are distributed to
Prosperity or to the Beneficial Owners as set out herein. The rights of the
Beneficial Owners hereunder, including any interest in or right to receive
Holdback Shares and dividends thereon held by any Beneficial Owner, are not
transferable or assignable by the Beneficial Owners other than by will or by the
laws of descent and distribution in the case of a natural person, or in the case
of a trust or entity, to any successor trustee or successor entity, including,
without limitation, the distribution to the beneficial owners in accordance with
the terms of the governing documents or under applicable law.

         5. Investment of Escrowed Funds. Pending distribution of any cash held
            ----------------------------
in the Escrow Account, the Escrow Agent shall invest and reinvest all cash
balances in the Escrow Account. The cash balances shall be invested in the
discretion of the Escrow Agent, provided that the Escrow Agent shall invest such
cash balances in a money market account providing an annual percentage yield
comparable to money market mutual funds to the extent prudent and practicable.
The Escrow Agent in its discretion may hold any portion of the funds held in the
Escrow Account in cash pending investment without liability for interest,
provided that the Escrow Agent shall not hold any portion of the funds held in
the Escrow Account uninvested for any period of time greater than the time
reasonably required to settle the sale or liquidation of any investment and to
settle the subsequent purchase of an investment as required herein. The Escrow
Agent will use its best efforts to collect investments at maturity but assumes
no responsibility for failure to do so as a result of any factor beyond its
control and shall not be obligated to institute or participate in any legal
proceedings relative thereto. The Escrow Agent shall not be responsible for any
loss resulting from

                                      B-2



any investment made in accordance with the provisions hereof or any loss
resulting from any such sale, absent the Escrow Agent's gross negligence or
willful misconduct. The Escrow Agent shall have no authority or obligation to
sell or liquidate any Holdback Shares held in the Escrow Account under any
circumstance.

         6. Disbursement From Escrow. The Holdback Shares shall be disposed of
            ------------------------
as follows:

            (a) Within ten (10) business days following the earlier of (i) the
third anniversary of the Closing Date or (ii) the date on which all Scheduled
Loans have been paid in full or upgraded as set forth below ("Holdback Payment
Date"), Prosperity shall deliver to the Escrow Agent and the Shareholder
Representative a written accounting (the "Notice") setting forth (i) any
Scheduled Loans (A) that have paid-off during such three-year period or (B) that
have been deemed by Prosperity's management, in its sole discretion, to no
longer be a Scheduled Loan based on the performance of the loan and the
financial stability of the borrower (collectively, "Satisfactory Loans");
provided, that renewed or restructured loans shall not be considered paid off
loans and (ii) the amount of any losses arising in the Scheduled Loans
(including all costs and expenses, including, without limitation, legal fees,
expenses, reasonable research time (as published by Prosperity) incurred in
investigating, attempting to collect or enforce the same) (the "Covered Losses")
incurred by Prosperity or its successor on or after the Closing Date.

            (b) Fifteen (15) business days after receipt of the Notice, the
Escrow Agent shall distribute to the Beneficial Owners (i) the aggregate number
of the Holdback Shares equal to (A) the Holdback Share Value less (x) the
Covered Losses and (y) the outstanding balance of Scheduled Loans on the
Holdback Payment Date, divided by (B) $16.275, or, if adjusted pursuant to
Section 2.2(c) of the Merger Agreement, by $12.205, (ii) any dividends with
respect to the Holdback Shares and (iii) an accompanying pro rata portion of the
cash paid in lieu of fractional shares (collectively, the "Holdback
Distribution"). Immediately prior to distribution of the Holdback Shares,
Prosperity shall deposit with the Escrow Agent cash sufficient to pay any
fractional shares and upon payment therefor such fractional shares shall be
returned to Prosperity. After the Holdback Distribution to the Beneficial
Owners, all of Prosperity's and the Escrow Agent's liabilities and obligations
to the Beneficial Owners in connection with the Holdback Shares, any dividends
with respect thereto, and cash, shall terminate.

            (c) Five (5) business days after the Holdback Distribution to the
Beneficial Owners, the Escrow Agent shall distribute the remaining Holdback
Shares and remaining dividends thereon and cash in the Escrow Account to
Prosperity. In the event of any return of Holdback Shares to Prosperity pursuant
to this Holdback Escrow Agreement, such Holdback Shares shall be deemed
repurchased by Prosperity as treasury stock as of the date of return of the
Holdback Shares. After all Holdback Shares have been distributed out `of the
Escrow Account, this Escrow Agreement shall terminate, whereupon all of the
Escrow Agent's liabilities and obligations in connection with the Holdback
Shares and cash shall terminate.

         7. Dividends or Other Proceeds. Dividends or other distributions paid
            ---------------------------
to the Escrow Agent with respect to the Holdback Shares then being held by the
Escrow Agent shall be allocated, distributed and paid to the Beneficial Owners
at the same time and in the same proportion as distribution of the Holdback
Shares, if any, along with dividends on the fractional shares that are returned
to Prosperity. No dividends or other proceeds will be paid to Beneficial Owners
with respect to any Holdback Shares that are distributed to Prosperity other
than those that relate to fractional shares.

                                       B-3



         8.  Changes to Capital Structure or Ownership. In the event that the
             -----------------------------------------
Prosperity Common Stock is changed into any shares of any other class, or if
Prosperity's capital structure is otherwise modified in a manner that
reclassifies the Prosperity Common Stock, then the Escrow Agent shall be given
full power and authority to tender any Holdback Shares for exchange or
modification, and thereafter such securities as have been received in exchange
shall be held as Holdback Shares for purposes of this Section 8.

         9.  Distributions to Beneficial Owners. Subject to Section 5 hereof,
             ----------------------------------
the Holdback Shares shall be distributed to the Beneficial Owners as follows:

             (a) Each Beneficial Owner will receive his or her pro rata share
(rounded to the nearest whole share) of any distribution made of the Holdback
Shares, and will receive an accompanying pro rata portion of the cash received
in lieu of any fractional share interest. Prosperity shall pay to each
Beneficial Owner otherwise entitled to receive such fractional share an amount
of cash determined by multiplying (i) the average closing price per share of
Prosperity Common Stock on The Nasdaq Stock Market, Inc. National Market System
("Nasdaq") (as reported by The Wall Street Journal or, if not reported thereby,
another alternative source as chosen by Prosperity) on the trading day
immediately prior to the day during which the Effective Time occurs by (ii) the
fraction of a share of Prosperity Common Stock which such holder would otherwise
be entitled to receive. For purposes of the first sentence in this paragraph,
each Beneficial Owner's pro rata share of the Holdback Shares shall be
determined by the number of Holdback Shares to be distributed multiplied by a
fraction the numerator of which is the number of shares of Paradigm Common Stock
held by that Beneficial Owner immediately prior to the Closing Date, and the
denominator of which is the total number of Paradigm shares outstanding on the
Closing Date (excluding for these purposes any shares attributable to
shareholders who have validly exercised their dissenters' rights). In the event
the Escrow Agent shall have any questions regarding the amount to be paid to any
Beneficial Owner, the Escrow Agent shall promptly refer such questions to the
Shareholder Representative for resolution. The Escrow Agent shall be entitled to
rely on the instructions and decisions of the Shareholder Representative with
respect to the amount to be paid to any Beneficial Owner, and the Escrow Agent
shall have no duty to determine or confirm the accuracy of any calculations or
other information provided to the Escrow Agent by the Shareholder
Representative.

             (b) Each Beneficial Owner shall provide the Escrow Agent with all
information and shall execute all documents deemed necessary or advisable by the
Escrow Agent as to the Holdback Shares. The Escrow Agent shall not be obligated
to make distributions to a Beneficial Owner until all such information and
documentation has been supplied to the Escrow Agent.

             (c) Each Beneficial Owner shall be responsible for complying with
Federal income tax laws as they relate to him or her.

         10. Shareholder Representative.
             --------------------------

             (a) Walter G. Finger shall be the initial representative for the
Beneficial Owners and shall have and exercise the responsibility and authority
set forth in this Escrow Agreement and shall have such authority on behalf of
the Beneficial Owners, and shall promptly and completely exercise such authority
in a timely manner to:

                                       B-4



                (i)   participate in, represent and bind the Beneficial Owners
in all respects with respect to any arbitration or legal proceeding relating to
this Escrow Agreement, including, without limitation, the defense and settlement
of any matter, and the calculation thereof for every purpose thereunder, consent
to jurisdiction, to enter into any settlement, and to entry of judgment, each
with respect to any or all of the Beneficial Owners; provided, however, the
Shareholder Representative shall have no authority under the Merger Agreement or
this Escrow Agreement to bind any Beneficial Owner to pay or return any money or
property other than the money and/or Holdback Shares that are then being held by
the Escrow Agent under this Escrow Agreement;

                (ii)  receive, comment on, accept and give notices and other
communications relating to this Escrow Agreement;

                (iii) take any action that the Shareholder Representative deems
necessary or desirable in order to fully effectuate the transactions
contemplated by this Escrow Agreement;

                (iv) vote the Holdback Shares in any action requiring a vote of
the shareholders of Prosperity until such Holdback Shares are distributed to
Prosperity or to the Beneficial Owners as set out herein; and

                (v)   execute and deliver any instrument or document that the
Shareholders Representative deems necessary or desirable in the exercise of his
authority under this Escrow Agreement.

            (b) Those Beneficial Owners who have the right to receive a majority
of the Prosperity Common Stock that may be distributed to the Beneficial Owners
out of the Escrow (a "Majority in Interest"), may at any time and by written
action delivered to the Escrow Agent, remove the Shareholder Representative or
any successor thereto, but such removal shall be effective only upon the
replacement of such Shareholder Representative or successor by a new Shareholder
Representative designated, by written notice delivered to the Escrow Agent by
those Beneficial Owners who hold a Majority in Interest; provided, however, that
any such notice shall be only effective upon actual receipt by the Escrow Agent.
Any such written notice shall be delivered to the Escrow Agent in accordance
with the notice provisions set forth herein. If any Shareholder Representative
shall have died, become incapacitated or unable to serve or resigned, those
Beneficial Owners who, as of immediately prior to the Effective Date, hold a
Majority in Interest shall promptly designate by written notice delivered to the
Escrow Agent, a replacement Shareholder Representative.

            (c) Any reasonable costs and expenses incurred by the Shareholder
Representative in connection with actions taken pursuant to or permitted by this
section will be borne, directly or indirectly, by the Beneficial Owners and paid
or reimbursed to the Shareholder Representative pro rata. If a Beneficial Owner
does not pay or reimburse such costs and expenses, the Shareholder
Representative may require that Holdback Shares or other property which would
otherwise be distributed to such Beneficial Owners pursuant to this Escrow
Agreement be distributed to the Shareholder Representative at any time in
connection with such reimbursement. Any such claims for reimbursement shall be
delivered to the Escrow Agent on or before the date of notice required pursuant
to Section 6(a) hereof.

            (d) All parties hereto shall be entitled to rely on all actions and
communications of any such Shareholder Representative as being genuine and
binding on all of the Beneficial Owners.

                                       B-5



              (e)  The Shareholder Representative shall have no liability to any
Beneficial Owner for any act or omission or obligation hereunder, provided that
such action or omission is taken by the Shareholder Representative in good faith
and without willful misconduct.

         11.  The Escrow Agent's Responsibilities.

              (a)  The Escrow Agent's Responsibilities. The Escrow Agent's sole
                   -----------------------------------
responsibilities with respect to the Holdback Shares and cash shall be for the
receipt and holding of the Holdback Shares in the Escrow Account, and the
disbursement thereof in accordance with this Escrow Agreement. The Escrow Agent
shall have no other responsibility or obligation of any kind, and shall not be
required to take any other action with reference to any matters that might
arise, in connection with the Holdback Shares and cash in the Escrow Account,
any dividends with respect thereto, or this Escrow Agreement. The Escrow Agent
may in accordance with this Escrow Agreement act upon (and shall be fully
protected in acting upon) any written instruction or other instrument that the
Escrow Agent in good faith believes to be genuine and what it purports to be.
The Escrow Agent shall not be liable to any person for anything that the Escrow
Agent may do or refrain from doing in accordance with this Escrow Agreement,
unless such action or inaction results from the Escrow Agent's gross negligence
or willful misconduct.

              The Escrow Agent has no duty to determine or inquire into any
happening or occurrence or any performance or failure of performance of the
Shareholder Representative with respect to agreements or arrangements with any
other party. The Escrow Agent shall not be required to determine the validity or
sufficiency, whether in form or in substance, of any instrument, document,
certificate, statement or notice referred to in this Escrow Agreement or
contemplated hereby, and it shall be sufficient if any writing purporting to be
such instrument, document, certificate, statement or notice is delivered to the
Escrow Agent and purports on its face to be correct in form and signed or
otherwise executed by the party or parties required to sign or execute the same
under this Escrow Agreement.

              The duties and responsibilities of the Escrow Agent hereunder
shall be determined solely by the express provisions of this Escrow Agreement
and no other or further duties or responsibilities shall be implied, including,
but not limited to, any obligation under or imposed by any laws of the State of
Texas upon fiduciaries.

              No shares of Prosperity Common Stock or monies with respect
thereto shall be disbursed by the Escrow Agent until it has collected such
shares and funds. The Escrow Agent shall act as a depository only, and the
Escrow Agent is not a party to, and is not bound by or charged with notice of,
any agreement out of which this escrow may arise, other than this Escrow
Agreement.

              (b)  Possible Disagreements. If any disagreement should arise
                   ----------------------
among any of the parties hereto or any other party (and the Escrow Agent is
notified in writing of such disagreement) with respect to the Holdback Shares or
cash held in the Escrow Account, any dividends with respect thereto, or this
Escrow Agreement, or if the Escrow Agent in good faith is in doubt as to what
action should be taken hereunder, the Escrow Agent shall have the absolute right
(but not the obligation) as its election to do either or both of the following:

                                      B-6



                   (i)  withhold or stop all further performance under this
         Escrow Agreement and all notices or instructions received in connection
         herewith until the Escrow Agent is satisfied that such disagreement or
         such doubt has been resolved; or

                   (ii) file a suit in interpleader and obtain an order from a
         court of appropriate jurisdiction requiring all persons involved to
         litigate in such court, at their own expense, their respective claims
         arising out of or in connection with the Holdback Shares and cash held
         in the Escrow Account and any dividends with respect thereto (the right
         of the Escrow Agent to institute such bill of interpleader, however,
         shall not be deemed to modify the manner in which the Escrow Agent is
         entitled to make disbursements of the Holdback Shares and cash held in
         the Escrow Account and any dividends with respect thereto as herein
         above set forth, other than to tender the Holdback Shares into a
         registry of such court).

         12.  Reimbursement of Expenses. The Escrow Agent will be reimbursed by
              -------------------------
Prosperity for the costs and expenses incurred by the Escrow Agent in connection
with the operation, administration and enforcement of this Escrow Agreement;
provided, however, that the Escrow Agent shall not have any right to
reimbursement for any such costs or expenses incurred as a result of the Escrow
Agent's acting outside the scope of its responsibilities and duties hereunder or
as a result of the Escrow Agent's gross negligence or willful misconduct.

         13.  Hold Harmless. The Shareholder Representative, on behalf of all of
              -------------
the Beneficial Owners, hereby releases, acquits and discharges the Escrow Agent
and agrees to hold the Escrow Agent and its officers, directors, employees,
agents and attorneys (collectively, the "Indemnitee") harmless from any and all
losses, costs, damages, expenses, claims and attorneys' fees suffered or
incurred by the Shareholder Representative or the Beneficial Owners as a result
of, in connection with or arising from or out of the acts or omissions of an
Indemnitee in performance of or pursuant to this Escrow Agreement, except such
acts or omissions as may result from such Indemnitee's willful misconduct or
gross negligence. All protections and indemnities benefiting the Escrow Agent
(and any other Indemnitee) are cumulative of any other rights it (or they) may
have by law or otherwise, and shall survive the termination of the Escrow
Agreement.

         14.  Miscellaneous.

              (a)  Notices. Any and all notices, requests, instructions and
                   -------

Escrow Agreement or any provision contained herein.

         (c) Specific Performance. The parties to this Escrow Agreement hereby
             --------------------
declare that it may be impossible to measure in money the damages that will
accrue to a party to this Escrow Agreement, his legal representatives,
successors or assigns by reason of a failure to perform any of the obligations
under this Escrow Agreement. Therefore, if a party hereto, his legal
representatives, successors or assigns shall institute any action or proceeding

any notice that is reasonably required under the terms of this Section 13 of
this Escrow Agreement, the prevailing party shall be entitled to recover
reasonable attorney's fees from the other party, which fees may be set by the
court in the trial of such action or may be enforced in a separate action
brought for that purpose, and which fees shall be in addition to any other
relief that may be awarded.

         (e) Assignment. This Escrow Agreement shall not be assigned by

July 22, 2002



Members of the Board of Directors
Paradigm Bancorporation, Inc.
3934 F.M. 1960, Suite 330
Houston, Texas 77068

Members of the Board:

You have requested our opinion as investment bankers as to the fairness, from a
financial point of view, to the shareholders of Paradigm Bancorporation, Inc.,
Houston, Texas ("Paradigm") of the consideration to be paid in connection with
the proposed merger of Paradigm with and into Prosperity Bancshares, Inc.,
Houston, Texas ("Prosperity") in accordance with the terms and conditions of the
Agreement and Plan of Reorganization, dated as of May 1, 2002, (the
"Agreement"). Pursuant to the Agreement and subject to the terms and conditions
therein, each share of Paradigm common stock outstanding prior to the effective
time of the merger will be converted into and exchanged for the right to
receive, for each share of Paradigm common stock they own, up to 1.08568 shares
of Prosperity common stock unless the exchange ratio is adjusted upward under
certain conditions. Of this amount, Paradigm shareholders will be entitled to
receive a minimum of 1.05489 shares of Prosperity common stock upon completion
of the merger and an additional 0.03169 shares of Prosperity common stock will
be deposited in a holdback escrow for possible future distributions to Paradigm
shareholders as provided in the Agreement. Subject to any adjustment, (1) an
aggregate of 2,505,379 shares of Prosperity common stock, less any shares that
would otherwise be distributed to shareholders who exercise dissenters' rights,
will be distributed to shareholders of Paradigm upon completion of the merger
and (2) an aggregate of up to 75,270 shares of Prosperity common stock, less any
shares that would otherwise be distributed to shareholders who exercise their
dissenters' rights, will be distributed in the holdback escrow for possible
future issuance as set forth in the Agreement.

Based on 2,375,020 common shares outstanding at Paradigm, the issuance of
2,505,379 shares of Prosperity common stock and a market price of $17.69 per
share for Prosperity common stock at July 18, 2002, the transaction value equals
$44,320,154. On a per share basis, each Paradigm shareholder will be entitled to
receive 1.05489 shares of Prosperity common stock at closing, or a transaction
value equivalent to $18.66 per share. We have assumed that none of the 75,270
holdback shares will be distributed to Paradigm shareholders. A transaction
value of $44,320,154 or $18.66 per share represents a price to stated book value




at March 31, 2002 of 2.41x, a price to tangible book value at March 31, 2002 of
2.94x, a price to 2001 earnings multiple of 39.70x and a price to estimated 2002
earnings multiple of 22.48x.

As part of its investment banking business, Hoefer & Arnett, Incorporated is
regularly engaged in the valuation of bank, bank holding company and thrift
securities in connection with mergers, acquisitions, underwritings, sales and
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes.

Hoefer & Arnett, is familiar with Paradigm, having provided certain financial
advice from time to time, including having provided financial advisory services
to Paradigm in September 1999 in connection with the acquisition of Dayton State
Bank and in connection with the terms of a common stock and trust preferred
securities offering. Paradigm paid Hoefer & Arnett $48,000 for such services. In
February of 2001, Hoefer and Arnett acted as Paradigm's co-underwriter in the
offering of $6,000,000 trust preferred securities. In connection with this
underwriting, Paradigm allowed Hoefer & Arnett a selling commission of $96,824.
In November of 1998, Hoefer & Arnett acted as Prosperity's co-underwriter in the
offering of $20,601,396 of common stock. In connection with this underwriting,
Prosperity allowed Hoefer & Arnett a selling commission of $394,792. Hoefer &
Arnett Incorporated provides a full range of financial advisory and securities
services and, in the course of its normal trading activities, may effect
transactions and hold securities of Prosperity for its own account and for the
accounts of customers.

In connection with this assignment, we have reviewed and analyzed, among other
things, the following: (i) the Agreement and Plan of Reorganization dated May 1,
2002; (ii) Annual Report on Form 10-KSB to shareholders of Paradigm for the year
ended December 31, 2001; Quarterly reports on Form Y-9C for the quarters ended
March, 31, 2002, December 31, 2001, September 30, 2001, June 30, 2001, March 31,
2001 and December 31, 2000; and internal financial statements as of June 30,
2002; (iii) Annual Reports to Shareholders and Annual Reports on Form 10-K of
Prosperity for December 31, 2001, December 31, 2000 and December 31, 1999;
Quarterly Reports on Form 10-Q of Prosperity for the quarters ended March 31,
2002, September 30, 2001, June 30, 2001 and March 31, 2001; and the press
release announcing June 30, 2002 financial results of Prosperity; (iv) certain
other publicly available financial and other information concerning Paradigm and
Prosperity; (v) publicly reported historical prices and trading activity for
Prosperity common stock; and (vi) the nature and terms of certain other merger
and acquisition transactions we believe relevant to our inquiry. We have held
discussions with senior management of Paradigm and Prosperity concerning their
past and current operations, financial condition and prospects, as well as the
results of regulatory examinations. We have conducted such other financial
studies, analyses and investigations, as we deemed appropriate for purposes of
this opinion.




In conducting our review, we have relied upon and assumed the accuracy and
completeness of the financial and other information provided to us or publicly
available, and we have not assumed any responsibility for independent
verification of the same. We have relied upon the management of Paradigm as to
the reasonableness of the financial and operating forecasts, projections (and
the assumptions and bases therefor) provided to us, and we have assumed that
such forecasts and projections reflect the best currently available estimates
and judgments of the management of Paradigm. Hoefer & Arnett relied on First
Call consensus earnings per share estimates for Prosperity for the years 2002
and 2003. We have also assumed, without assuming any responsibility for the
independent verification of same, that the aggregate allowance for loan losses
for Paradigm and Prosperity is adequate to cover such losses. We have not made
or obtained any evaluations or appraisals of the property of Paradigm or
Prosperity, nor have we examined any individual loan credit files. Our opinion
as expressed herein is limited to the fairness, from a financial point of view,
to the holders of the common shares of Paradigm of the terms of the proposed
merger of Paradigm with and into Prosperity and does not address Paradigm's
underlying business decision to proceed with the transaction.

We have considered such financial and other factors as we have deemed
appropriate under the circumstances, including among others the following: (i)
the historical and current financial position and results of operations of
Paradigm and Prosperity, including interest income, interest expense, net
interest income, net interest margin, provision for loan losses, non-interest
income, non-interest expense, earnings, dividends, internal capital generation,
book value, intangible assets, return on assets, return on shareholders' equity,
capitalization, the amount and type of non-performing assets, loan losses and
the reserve for loan losses, all as set forth in the financial statements for
Paradigm and Prosperity; (ii) the assets and liabilities of Paradigm and
Prosperity, including the loan, investment and mortgage portfolios, deposits,
other liabilities, historical and current liability sources and costs and
liquidity; and (iii) the nature and terms of certain other merger and
acquisition transactions involving banks and bank holding companies. We have
also taken into account our assessment of general economic, market and financial
conditions and our experience in other transactions, as well as our experience
in securities valuation and our knowledge of the banking industry generally. Our
opinion is necessarily based upon conditions as they exist and can be evaluated
on the date hereof and the information made available to us through the date
hereof.

Based upon and subject to the foregoing, we are of the opinion as investment
bankers that, as of the date hereof, the terms of the proposed merger of
Paradigm with and into Prosperity are fair, from a financial point of view, to
the holders of shares of Paradigm common stock.

Our opinion is directed to the Board of Directors of Paradigm for its
information and assistance in connection with its consideration of the financial
terms of the transaction



contemplated by the Agreement and does not constitute a recommendation to any
shareholder of Paradigm as to how such shareholder should vote on the proposed
transaction. We hereby consent to the reference to our firm in the proxy
statement related to the transaction and to the inclusion of our opinion as an
exhibit to the proxy statement related to the transaction.

     A. Any shareholder of a domestic corporation shall have the right to
dissent from any of the following corporate actions:

               (1) Any plan of merger to which the corporation is a party if
shareholder approval is required by Article 5.03 or 5.16 of this Act and the
shareholder holds shares of a class or series that was entitled to vote thereon
as a class or otherwise;

               (2) Any sale, lease, exchange or other disposition (not including
any pledge, mortgage, deed of trust or trust indenture unless otherwise provided
in the articles of incorporation) of all, or substantially all, the property and
assets, with or without goodwill, of a corporation requiring the special
authorization of the shareholders as provided by this Act;

               (3) Any plan of exchange pursuant to Article 5.02 of this Act in
which the shares of the corporation of the class or series held by the
shareholder are to be acquired.

     B. Notwithstanding the provisions of Section A of this Article, a
shareholder shall not have the right to dissent from any plan of merger in which
there is a single surviving or new domestic or foreign corporation, or from any
plan of exchange, if:

          (2)  the shareholder is not required by the terms of the plan of

series of shares held by such shareholder; and

          (3)  the shareholder is not required by the terms of the plan of
merger or the plan of exchange to accept for the shareholder's shares any

immediately after the effective time of the merger or exchange, will be part of

                 (c)  any combination of the securities and cash described in
Subdivisions (a) and (b) of this subsection.

Article 5.12.  Procedure for Dissent by Shareholders as to Said Corporate
               Actions

     A.   Any shareholder of any domestic corporation who has the right to
dissent from any of the corporate actions referred to in Article 5.11 of this
Act may exercise that right to dissent only by complying with the following
procedures:

          (1)(a) With respect to proposed corporate action that is submitted to
a vote of shareholders at a meeting, the shareholder shall file with the
corporation, prior to the meeting, a written objection to the action, setting
out that the shareholder's right to dissent will be exercised if the action is
effective and giving the shareholder's address, to which notice thereof shall be
delivered or mailed in that event. If the action is effected and the shareholder
shall not have voted in favor of the action, the corporation, in the case of
action other than a merger, or the surviving or new corporation (foreign or
domestic) or other entity that is liable to discharge the shareholder's right of
dissent, in the case of a merger, shall, within ten (10) days after the action
is effected, deliver or mail to the shareholder written notice that the action
has been effected, and the shareholder may, within ten (10) days from the
delivery or mailing of the notice, make written demand on the existing,
surviving, or new corporation (foreign or domestic) or other entity, as the case
may be, for payment of the fair value of the shareholder's shares. The fair
value of the shares shall be the value thereof as of the day immediately
preceding the meeting, excluding any appreciation or depreciation in
anticipation of the proposed action. The demand shall state the number and class
of the shares owned by the shareholder and the fair value of the shares as
estimated by the shareholder. Any shareholder failing to make demand within the
ten (10) day period shall be bound by the action.

          (b)    With respect to proposed corporate action that is approved
pursuant to Section A of Article 9.10 of this Act, the corporation, in the case
of action other than a merger, and the surviving or new corporation (foreign or
domestic) or other entity that is liable to discharge the shareholder's right of
dissent, in the case of a merger, shall, within ten (10) days after the date the
action is effected, mail to each shareholder of record as of the effective date
of the action notice of the fact and date of the action and that the shareholder
may exercise the

                                       -2-



shareholder's right to dissent from the action. The notice shall be accompanied
by a copy of this Article and any articles or documents filed by the corporation
with the Secretary of State to effect the action. If the shareholder shall not
have consented to the taking of the action, the shareholder may, within twenty
(20) days after the mailing of the notice, make written demand on the existing,
surviving, or new corporation (foreign or domestic) or other entity, as the case
may be, for payment of the fair value of the shareholder's shares. The fair
value of the shares shall be the value thereof as of the date the written
consent authorizing the action was delivered to the corporation pursuant to
Section A of Article 9.10 of this Act, excluding any appreciation or
depreciation in anticipation of the action. The demand shall state the number
and class of shares owned by the dissenting shareholder and the fair value of
the shares as estimated by the shareholder. Any shareholder failing to make
demand within the twenty (20) day period shall be bound by the action.

         (2) Within twenty (20) days after receipt by the existing, surviving,
or new corporation (foreign or domestic) or other entity, as the case may be, of
a demand for payment made by a dissenting shareholder in accordance with
Subsection (1) of this Section, the corporation (foreign or domestic) or other
entity shall deliver or mail to the shareholder a written notice that shall
either set out that the corporation (foreign or domestic) or other entity
accepts the amount claimed in the demand and agrees to pay that amount within
ninety (90) days after the date on which the action was effected, and, in the
case of shares represented by certificates, upon the surrender of the
certificates duly endorsed, or shall contain an estimate by the corporation
(foreign or domestic) or other entity of the fair value of the shares, together
with an offer to pay the amount of that estimate within ninety (90) days after
the date on which the action was effected, upon receipt of notice within sixty
(60) days after that date from the shareholder that the shareholder agrees to
accept that amount and, in the case of shares represented by certificates, upon
the surrender of the certificates duly endorsed.

         (3) If, within sixty (60) days after the date on which the corporate
action was effected, the value of the shares is agreed upon between the
shareholder and the existing, surviving, or new corporation (foreign or
domestic) or other entity, as the case may be, payment for the shares shall be
made within ninety (90) days after the date on which the action was effected,
and in the case of shares represented by certificates, upon surrender of the
certificates duly endorsed. Upon payment of the agreed value, the shareholder
shall cease to have any interest in the shares or in the corporation.

         B.  If, within the period of sixty (60) days after the date on which
the corporate action was effected, the shareholder and the existing, surviving,
or new corporation (foreign or domestic) or other entity, as the case may be, do
not so agree, then the shareholder or the corporation (foreign or domestic) or
other entity may, within sixty (60) days after the expiration of the sixty (60)
day period, file a petition in any court of competent jurisdiction in the county
in which the principal office of the domestic corporation is located, asking for
a finding and determination of the fair value of the shareholder's shares. Upon
the filing of any such petition by the shareholder, service or a copy thereof
shall be made upon the corporation (foreign or domestic) or other entity, which
shall, within ten (10) days after service, file in the office of the clerk of
the court in which the petition was filed a list containing the names and
addresses of all shareholders of the domestic corporation who have demanded
payment for their shares and with whom agreements as to the value of their
shares have not been reached by the corporation

                                       -3-



(foreign or domestic) or other entity. If the petition shall be filed by the
corporation (foreign or domestic) or other entity, the petition shall be
accompanied by such a list. The clerk of the court shall give notice of the time
and place fixed for the hearing of the petition by registered mail to the
corporation (foreign or domestic) or other entity and to the shareholders named
on the list at the addresses therein stated. The forms of the notices by mail
shall be approved by the court. All shareholders thus notified and the
corporation (foreign or domestic) or other entity shall thereafter be bound by
the final judgment of the court.

         C. After the hearing of the petition, the court shall determine the
shareholders who have complied with the provisions of this Article and have
become entitled to the valuation of and payment for their shares, and shall
appoint one or more qualified appraisers to determine that value. The appraisers
shall have power to examine any of the books and records of the corporation the
shares of which they are charged with the duty of valuing, and they shall make a
determination of the fair value of the shares upon such investigation as to them
may seem proper. The appraisers shall also afford a reasonable opportunity to
the parties interested to submit to them pertinent evidence as to the value of
the shares. The appraisers shall also have such power and authority as may be
conferred on Masters in Chancery by the Rules of Civil Procedure or by the order
of their appointment.

         D. The appraisers shall determine the fair value of the shares of the
shareholders adjudged by the court to be entitled to payment for their shares
and shall file their report of their value in the office of the clerk of the
court. Notice of the filing of the report shall be given by the clerk to the
parties in interest. The report shall be subject to exceptions to be heard
before the court both upon the law and the facts. The court shall by its
judgment determine the fair value of the shares of the shareholders entitled to
payment for their shares and shall direct the payment of that value by the
existing, surviving, or new corporation (foreign or domestic) or other entity,
together with interest thereon, beginning 91 days after the date on which the
applicable corporate action from which the shareholder elected to dissent was
affected to the date of such judgment, to the shareholders entitled to payment.
The judgment shall be payable to the holders of uncertificated shares
immediately but to the holders of shares represented by certificates only upon,
and simultaneously with, the surrender to the existing, surviving, or new
corporation (foreign or domestic) or other entity, as the case may be, of duly
endorsed certificates for those shares. Upon payment of the judgment, the
dissenting shareholders shall cease to have any interest in those shares or in
the corporation. The court shall allow the appraisers a reasonable fee as court
costs, and all court costs shall be allotted between the parties in the manner
that the court determines to be fair and equitable.

         E. Shares acquired by the existing, surviving, or new corporation
(foreign or domestic) or other entity, as the case may be, pursuant to the
payment of the agreed value of the shares or pursuant to payment of the judgment
entered for the value of the shares, as in this Article provided, shall, in the
case of a merger, be treated as provided in the plan of merger and, in all other
cases, may be held and disposed of by the corporation as in the case of other
treasury shares.

         F. The provisions of this Article shall not apply to a merger if, on
the date of the filing of the articles of merger, the surviving corporation is
the owner of all the outstanding shares of the other corporations, domestic or
foreign, that are parties to the merger.

                                       -4-



         G.    In the absence of fraud in the transaction, the remedy provided
by this Article to a shareholder objecting to any corporate action referred to
in Article 5.11 of this Act is the exclusive remedy for the recovery of the
value of his shares or money damages to the shareholder with respect to the
action. If the existing, surviving, or new corporation (foreign or domestic) or
other entity, as the case may be, complies with the requirements of this
Article, any shareholder who fails to comply with the requirements of this
Article shall not be entitled to bring suit for the recovery of the value of his
shares or money damages to the shareholder with respect to the action.

Article 5.13.  Provisions Affecting Remedies of Dissenting Shareholders

         A.    Any shareholder who has demanded payment for his shares in
accordance with either Article 5.12 or 5.16 of this Act shall not thereafter be
entitled to vote or exercise any other rights of a shareholder except the right
to receive payment for his shares pursuant to the provisions of those articles
and the right to maintain an appropriate action to obtain relief on the ground
that the corporate action would be or was fraudulent, and the respective shares
for which payment has been demanded shall not thereafter be considered
outstanding for the purposes of any subsequent vote of shareholders.

         B.    Upon receiving a demand for payment from any dissenting
shareholder, the corporation shall make an appropriate notation thereof in its
shareholder records. Within twenty (20) days after demanding payment for his
shares in accordance with either Article 5.12 or 5.16 of this Act, each holder
of certificates representing shares so demanding payment shall submit such
certificates to the corporation for notation thereon that such demand has been
made. The failure of holders of certificated shares to do so shall, at the
option of the corporation, terminate such shareholder's rights under Articles
5.12 and 5.16 of this Act unless a court of competent jurisdiction for good and
sufficient cause shown shall otherwise direct. If uncertificated shares for
which payment has been demanded or shares represented by a certificate on which
notation has been so made shall be transferred, any new certificate issued
therefor shall bear similar notation together with the name of the original
dissenting holder of such shares and a transferee of such shares shall acquire
by such transfer no rights in the corporation other than those which the
original dissenting shareholder had after making demand for payment of the fair
value thereof.

         C.    Any shareholder who has demanded payment for his shares in
accordance with either Article 5.12 or 5.16 of this Act may withdraw such demand
at any time before payment for his shares or before any petition has been filed
pursuant to Article 5.12 or 5.16 of this Act asking for a finding and
determination of the fair value of such shares, but no such demand may be
withdrawn after such payment has been made or, unless the corporation shall
consent thereto, after any such petition has been filed. If, however, such
demand shall be withdrawn as hereinbefore provided, or if pursuant to Section B
of this Article the corporation shall terminate the shareholder's rights under
Article 5.12 of 5.16 of this Act, as the case may be, or if no petition asking
for a finding and determination of fair value of such shares by a court shall
have been filed within the time provided in Article 5.12 or 5.16 of this Act, as
the case may be, or if after the hearing of a petition filed pursuant to Article
5.12 or 5.16, the court shall determine that such shareholder is not entitled to
the relief provided by those articles, then, in any such case, such shareholder
and all persons claiming under him shall be conclusively presumed to have

                                       -5-



approved and ratified the corporate action from which he dissented and shall be
bound thereby, the right of such shareholder to be paid the fair value of his
shares shall cease, and his status as a shareholder shall be restored without
prejudice to any corporate proceedings which may have been taken during the
interim, and such shareholders shall be entitled to receive any dividends or
other distributions made to shareholders in the interim.

                                       -6-



                                     PART II
                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

         The Registrant's Articles of Incorporation and Bylaws require the
Registrant to indemnify officers and directors of the Registrant to the fullest
extent permitted by Article 2.02-1 of the Business Corporation Act of the State
of Texas (the "TBCA"). The Articles of Incorporation and Bylaws of the
Registrant are filed as Exhibit 3.1 and 3.2 to the Registration Statement.
Generally, Article 2.02-1 of the TBCA permits a corporation to indemnify a
person who was, is, or is threatened to be made a named defendant or respondent
in a proceeding because the person was or is a director or officer if it is
determined that such person (i) conducted himself in good faith; (ii) reasonably
believed (a) in the case of conduct in his official capacity as a director or
officer of the corporation, that his conduct was in the corporation's best
interests; and/or (b) in other cases, that his conduct was at least not opposed
to the corporation's best interests; and (iii) in the case of any criminal
proceeding, had no reasonable cause to believe that his conduct was unlawful. In
addition, the TBCA requires a corporation to indemnify a director or officer for
any action that such director or officer is wholly successfully in defending on
the merits.

         The Registrant's Articles of Incorporation provide that a director of
the Registrant will not be liable to the corporation for monetary damages for an
act or omission in the director's capacity as a director, except to the extent
not permitted by law. Texas law does not permit exculpation of liability in the
case of (i) a breach of the director's duty of loyalty to the corporation or its
shareholders; (ii) an act or omission not in good faith that constitutes a
breach of duty of the director to the corporation or that involves intentional
misconduct or a knowing violation of the law; (iii) a transaction from which a
director received an improper benefit, whether or not the benefit resulted from
an action taken within the scope of the director's office; or (iv) an act or
omission for which the liability of the director is expressly provided by
statute.

         The Registrant may provide liability insurance for each director and
officer for certain losses arising from claims or changes made against them
while acting in their capabilities as directors or officers of the Registrant,
whether or not the Registrant would have the power to indemnify such person
against such liability, as permitted by law.

Item 22.  Undertakings

(a)     The undersigned registrant hereby undertakes:

        (1)   To file, during any period in which offers or sales are being
              made, a post-effective amendment to this Registration Statement:

              (i)      To include any prospectus required by Section 10(a)(3) of
                       the Securities Act of 1933;

              (ii)     To reflect in the prospectus any facts or events arising
                       after the effective date of the registration statement
                       (or the most recent post-effective amendment thereof),
                       which, individually or in the aggregate, represent a
                       fundamental change in the information set forth in the
                       registration statement. Notwithstanding the foregoing,
                       any increase or decrease in volume of securities offered
                       (if the total dollar value of securities offered would
                       not exceed that which was registered) and any deviation
                       from the low or high end of the estimated maximum
                       offering range may be reflected in the form of prospectus
                       filed with the Commission pursuant to Rule 424(b) if, in
                       the aggregate, the changes in volume and price represent
                       no more than a 20 percent change in the maximum aggregate
                       offering price set forth in the "Calculation of
                       Registration Fee" table in the effective Registration
                       Statement;

              (iii)    To include any material information with respect to the
                       plan of distribution not previously disclosed in the
                       Registration Statement or any material change to such
                       information in the Registration Statement.

        (2)   That, for the purpose of determining any liability under the
              Securities Act of 1933, each such post-effective amendment shall
              be deemed to be a new registration statement relating to the
              securities offered therein, and the offering of such securities at
              that time shall be deemed to be the initial bona fide offering
              thereof.

        (3)   To remove from registration by means of a post-effective
              amendment any of the securities being registered which remain
              unsold at the termination of the offering.

(b)     The undersigned Registrant hereby undertakes that, for purposes of
        determining any liability under the Securities Act, each filing of the
        registrant's annual report pursuant to Section 13(a) or Section 15(d)
        of the Securities Exchange Act of 1934, as amended (and, where
        applicable, each filing of an employee benefit plan's annual report
        pursuant to section 15(d) of the Exchange Act) that is incorporated by
        reference in the Registration Statement shall be deemed to be a new
        Registration Statement relating to the securities offered therein, and
        the offering of such securities at that time shall be deemed to be the
        initial bona fide offering thereof.

(g)

        (1)   The undersigned registrant hereby undertakes as follows: that
              prior to any public reoffering of the securities registered
              hereunder through use of a prospectus which is a part of this
              registration statement, by any person or party who is deemed
              to be an underwriter within the meaning of Rule 145(c), the
              issuer undertakes that such reoffering prospectus will contain
              the information called for by the applicable registration form
              with respect to reofferings by persons who may be deemed
              underwriters, in addition to the information called for by the
              other items of the applicable form.

                                      II-4



        (2)   The registrant undertakes that every prospectus: (i) that is
              filed pursuant to paragraph (1) immediately preceding; or (ii)
              that purports to meet the requirements of Section 10(a)(3) of
              the Act and is used in connection with an offering of
              securities subject to Rule 415, will be filed as a part of an
              amendment to the registration statement and will not be used
              until such amendment is effective, and that, for purposes of
              determining any liability under the Securities Act of 1933,
              each such post-effective amendment shall be deemed to be a new
              registration statement relating to the securities offered
              therein, and the offering of such securities at that time
              shall be deemed to be the initial bona fide offering thereof.

   (h)  Insofar as indemnification for liabilities arising under the
        Securities Act of 1933 may be permitted to directors, officers and
        controlling persons of the Registrant pursuant to the foregoing
        provisions, or otherwise, the registrant has been advised that in the
        opinion of the Securities and Exchange Commission, such
        indemnification is against public policy as expressed in the
        Securities Act and is, therefore, unenforceable. In the event that a
        claim for indemnification against such liabilities (other than the
        payment by the registrant of expenses incurred or paid by a director,
        officer or controlling person of the registrant in the successful
        defense of any action, suit or proceeding) is asserted by such
        director, officer or controlling person in connection with the
        securities being registered, the registrant will, unless in the
        opinion of its counsel the matter has been settled by controlling
        precedent, submit to a court of appropriate jurisdiction the question
        whether such indemnification by it is against public policy as
        expressed in the Securities Act and will be governed by the final
        adjudication of such issue.

        The undersigned registrant hereby undertakes to respond to requests for
        information that is incorporated by reference into the prospectus
        pursuant to Item 4, 10(b), 11 or 13 of this Form, within one business
        day of receipt of such request, and to send the incorporated documents
        by first class mail or other equally prompt means. This includes
        information contained in documents filed subsequent to the effective
        date of the registration statement through the date of responding to
        the request.

        The undersigned registrant hereby undertakes to supply by means of a
        post-effective amendment all information concerning a transaction, and
        the company being acquired involved therein, that was not the subject
        of and included in the registration statement when it became effective.

                                      II-5
