QUESTIONS AND ANSWERS
===============================================================================

Q: Who Can Vote?

A: You can vote if you were a stockholder at the close of business on the record
   date, March 9, 2003. On that date, there were 43,514,317 shares outstanding
   and entitled to vote at the annual meeting.

Q: Who Can Attend The Meeting?

A: All stockholders can attend.

Q: What Am I Voting On?

A: You are voting on:

   .  The election of two nominees as directors for terms that expire in 2006.
      The board of directors' nominees are John G. Nikkel and John S. Zink.

   .  The ratification of the appointment of PricewaterhouseCoopers LLP as
      independent auditors for 2003.

   The two nominees for director who receive the most votes will be elected.
   For the other proposal to be approved, more votes must be cast for it than
   against it.

Q: How Will The Proxies Vote On Any Other Business Brought Up At The Meeting?

A: By submitting your proxy, you authorize the proxies to use their judgment to
   determine how to vote on any other matter brought before the annual meeting.
   We do not know of any other business to be considered at the annual meeting.

   The proxies' authority to vote according to their judgment applies only to
   shares you own as a stockholder of record.

Q: How Do I Cast My Vote?

A: If you hold your shares as a stockholder of record, you can vote in person at
   the annual meeting or you can vote by mail, telephone or the Internet. If you
   are a street-name stockholder, you will receive instructions from your bank,
   broker or other nominee describing how to vote your shares.

   The enclosed proxy contains instructions for mail voting or for voting by
   way of telephone or the Internet. The proxies identified on the back of the
   proxy will vote the shares of which you are the stockholder of record in
   accordance with your instructions. If you submit a proxy without giving
   specific voting instructions, the proxies will vote those shares as
   recommended by the board of directors.

Q: How Does The Board Recommend I Vote On The Proposals?

A: The board recommends you vote for each of the proposals.

Q: Can I Revoke My Proxy?

A: Yes. You can revoke your proxy by:

   .  Submitting a new proxy;
   .  Giving written notice before the meeting to our secretary stating that
      you are revoking your proxy; or
   .  Attending the meeting and voting your shares in person.

Q: Who Will Count The Vote?

A: Mellon Investor Services LLC, our transfer agent, will count the vote.
   Representatives of Mellon Investor Services LLC will act as the inspectors
   of election.

                                       1

Q: What Is A "Quorum"?

A: A quorum is the number of shares that must be present to hold the annual
   meeting. The quorum requirement for the annual meeting is a majority of the
   outstanding shares as of the record date, present in person or represented by
   proxy. If you submit a valid proxy or attend the annual meeting, your shares
   will be counted to determine whether there is a quorum.

   Abstentions and broker non-votes count toward the quorum. "Broker non-votes"
   occur when nominees (such as banks and brokers) that hold shares on behalf of
   beneficial owners do not receive voting instructions from the beneficial
   owners by ten days before the meeting and do not have discretionary voting
   authority to vote those shares.

Q: Will Broker Non-Votes Or Abstentions Affect The Voting Results?

A: Although abstentions and broker non-votes count for quorum purposes, they do
   not count as votes for or against a proposal. As a result, abstentions and
   broker non-votes will not affect the voting results on the election of
   directors or the ratification of the appointment of auditors.

Q: What Shares Are Included On My Proxy?

A: Your proxy represents all shares registered to your account in the same
   social security number and address.

Q: What Does It Mean If I Get More Than One Proxy?

A: Your shares are probably registered in more than one account. You should vote
   each proxy you receive. We encourage you to consolidate all your accounts by
   registering them in the same name, social security number and address.

Q: How Many Votes Can I Cast?

A: On each matter, including each director position, you are entitled to one
   vote per share.

Q: When Are Stockholder Proposals Due For The 2004 Annual Meeting Of
   Stockholders?

A: If you want to present a qualified proposal from the floor at the 2004 annual
   meeting, you must give us written notice of your proposal no earlier than
   January 1, 2004 and no later than January 31, 2004. Your notice should be
   sent to the Senior Vice President, General Counsel and Secretary, Unit
   Corporation, 1000 Kensington Tower I, 7130 South Lewis, Tulsa, Oklahoma
   74136.

   If instead of presenting your proposal at the meeting you want your proposal
   to be considered for inclusion in next year's proxy statement, you must
   submit the proposal in writing to our Senior Vice President, General Counsel
   and Secretary so that it is received at the above address by November 20,
   2003.

Q: How Is This Proxy Solicitation Being Conducted?

A: We hired Regan & Associates, New York, New York, to assist in the
   distribution of proxy materials and solicitation of votes for a fee of $7,000
   with all of our out-of-pocket expenses included. We will reimburse brokerage
   houses and other custodians, nominees and fiduciaries for their reasonable
   out-of-pocket expenses for forwarding proxy and solicitation materials to
   stockholders. In addition, some of our employees may solicit proxies. Regan &
   Associates and our employees may solicit proxies in person, by telephone and
   by mail. None of our employees will receive special compensation for these
   services, which the employees will perform as part of their regular duties.

                                       2


ITEM 1: ELECTION OF DIRECTORS
===============================================================================

Item 1 is the election of two directors to the board of directors. Our board is
composed of eight members and is divided into three classes with each director
serving for a three-year term. At each annual meeting, the term of one class
expires. The term of service for those directors serving in Class I expires at
this meeting.

We know of no reason why any nominee may be unable to serve as a director. If
any nominee is unable to serve, your proxy may vote for another nominee proposed
by the board, or the board may reduce the number of directors to be elected.

If any director resigns, dies or is otherwise unable to serve out his or her
term, or the board increases the number of directors, the board may fill the
vacancy.

Our Nominating & Governance Committee has recommended, and the board of
directors has approved, the nominees listed below to stand for election.
Information concerning each nominee and each continuing director is provided
below.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE IN FAVOR OF ELECTING THE TWO
NOMINEES.

   .  $2,000 annual fee for service on each committee
   .  $1,000 board meeting attendance fee
   .  $500 committee meeting attendance fee

Expenses:

   .  We reimburse all non-employee directors for travel expenses incurred

Stock Options:

   .  Each non-employee director automatically receives an option to purchase
      3,500 shares of common stock on the first business day following each
      annual meeting of our stockholders. The option exercise price is the
      fair market value of our common stock on such date. Payment of the
      exercise price may be made in cash or in shares of common stock that
      have been held by the director for at least one year. No stock option
      may be exercised during the first six months of its term except in the
      case of death. Each option has a ten-year term. In 2002 stock options
      were granted for an aggregate of 21,000 shares at $20.10 per share. An
      aggregate of 62,000 shares are subject to currently outstanding

(1)  Value realized equals fair market value of the stock on date of exercise,
     less the exercise price, times the number of shares acquired.

(2)  The value of unexercised in-the-money options at year end assumes a fair
     market value for the Company's common stock of $18.80, the average of the
     high and low prices of the Company's common stock on the New York Stock
     Exchange on December 31, 2002. Value is calculated on the basis of the
     difference between $18.80 and the option exercise price multiplied by the
     number of shares of common stock underlying the options.

     Lamborn and Keeley vested 50% on December 31, 2002 and 50% will vest on
     December 31, 2003. All options vest immediately in the event of a "change
     in control," as defined in the plan.

(2)  Based on a total of 160,000 options being granted to certain employees
     during fiscal 2002.

(3)  Caution is recommended in interpreting the financial significance of
     these figures. They are calculated by multiplying the number of options
     granted by the difference between a future hypothetical stock price and
     the option exercise price and are shown pursuant to rules of the
     Securities and Exchange Commission. They assume the value of the Company
     Common Stock appreciates 5% and 10% each year, compounded annually, for
     ten years (the life of each option). They are not intended to forecast
     possible future appreciation, if any, of such stock price or to establish
     a present value of options. Also, if appreciation does not occur at the
     5% or 10% per year rate, the amounts shown would not be realized by the
     year 2012. Depending on inflation rates, these amounts may be worth
     significantly less in 2012, in real terms, than their value today.

Long Term Performance Plans and Pension Plans

We do not currently have any long term performance plans or pension plans.

TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL ARRANGEMENTS
===============================================================================

Stock Option Plan

Our stock option plan contains a provision vesting all stock options in the
event of a "change-in-control" of us. A "change-in-control" is deemed to have
occurred at such time

                                       11


as any person or group, other than Unit or an Exempt Person, is or becomes the
beneficial owner, directly or indirectly, of our securities representing 50% or
more of the combined voting power of our then outstanding securities. An Exempt
Person is generally defined to be any person (or estate or trust of such person)
who, on the date of the plan, owned securities representing more than 20% of the
combined voting power of our then outstanding securities, and any spouse, parent
or issue of such person.

Separation Benefit Plan

On December 20, 1996, effective as of January 1, 1997, the board adopted the
Separation Benefit Plan of Unit Corporation and Participating Subsidiaries (the
"Plan"). The Plan is generally applicable to all of our full time salaried
employees and to the employees of our two principal subsidiaries, excluding any
employees who are also our directors, who have been with their employer for at
least one year. Subject to the terms of the Plan, any eligible employee whose
employment is terminated is entitled to receive a separation benefit in an
amount calculated by dividing the eligible employee's average annual base salary
in effect immediately prior to such employee's separation by 52 to determine a
weekly separation benefit amount. The number of weekly separation benefit
payments then payable to an eligible employee is calculated based on the
employee's years of service in accordance with a schedule set forth in the Plan.
Employees who voluntarily leave their employment are not entitled to receive a
separation benefit unless they have completed at least 20 years of service. Any
eligible employee who has completed 20 years of service or more is vested in his
or her separation benefit, subject to fulfilling the other requirements of the
Plan. Separation benefit payments are limited to a maximum of 104 weekly
payments. The Plan also provides that, unless otherwise provided by our board of
directors prior to a "change-in-control" of us, as defined in the Plan, all
eligible employees shall be vested in their separation benefit as of the date of
such "change-in-control" based on their years of service. As a condition to
receiving the separation benefits, employees must sign a separation agreement
waiving any claims the employee may have against our subsidiaries or us.

Senior Management Separation Benefit Plan

On October 28, 1997, the board adopted the Separation Benefit Plan for Senior
Management. This plan is similar in terms to the benefits and requirements
described above for the Separation Benefit Plan, with the exception that the
compensation committee determines who will participate in this plan. In
addition, the committee is given the authority to increase (up to a maximum of
104) the number of weekly separation benefit payments a participant would
otherwise be entitled to receive under the plan if the participant is
involuntarily terminated. Currently, only Messrs. Kirchner, Lamborn and Nikkel
are participants in this plan.

Change of Control Arrangements

We have entered into key employee change of control contracts with Messrs.
Nikkel, Lamborn, Keeley, Pinkston and Schell. These severance contracts have an
initial three-year term that is automatically extended for one year upon each
anniversary, unless a notice not to extend is given by us. If a change of
control of the company (as defined below) occurs during the term of the
severance contract, then the contract becomes operative for a fixed three-year
period. The severance contracts generally provide that the executive's terms and
conditions of employment (including position, work location, compensation and
benefits) will not be adversely changed during the three-year period after a
change of control. If the executive's employment is terminated by the company
(other than for cause, death or disability), the executive terminates for good
reason during such three-year period, or the executive terminates employment for
any reason during the 30-day period following the first anniversary of the
change of control, and upon certain terminations prior to a change of control or
in connection with or in anticipation of a change of control, the executive is
generally entitled to receive the following payment and benefits:

                                       12

   .  earned but unpaid compensation;

   .  up to 2.9 times the executive's base salary plus annual bonus (based
      on historic annual bonus); and

   .  the company matching contributions that would have been made had the
      executive continued to participate in the company's 401(k) plan for up
      to an additional three years.

In addition, the severance contract provides for a continuation of various
medical, dental, disability and life insurance plans and financial counseling
for a period of up to three years, outplacement services and the payment of all
legal fees and expenses incurred by the executive in enforcing any right or
benefit provided by the severance contracts. The severance contract provides
that the executive is entitled to receive a payment in an amount sufficient to
make the executive whole for any excise tax on excess parachute payments imposed
under Section 4999 of the Code. As a condition to receipt of these severance
benefits, the executive must remain in the employ of the company and render
services commensurate with his position. The executive must also agree to retain
in confidence any and all confidential information known to him concerning the
company and its business so long as the information is not otherwise publicly
disclosed. As of the date of this proxy statement, no amounts have been paid
under the severance contracts.

For purposes of the severance contracts, a change of control is generally
defined as:

(1) Any individual, entity or group acquiring beneficial ownership of 15% or
more of either the outstanding shares of the company's common stock or the
combined voting power of the outstanding voting securities of the company
entitled to vote generally for the election of directors;

(2) Individuals who constitute the board on the date hereof cease to constitute
a majority of the board, provided that an individual whose election or
nomination as a director is approved by a vote of at least a majority of the
directors as of the date hereof will be deemed a member of the incumbent board;

(3) Approval by the company's stockholders of a reorganization, merger or
consolidation or sale or other disposition of all or substantially all of the
assets of the company or the acquisition of assets of another entity, unless
following the business combination:

   .  all or substantially all of the beneficial owners of the company's
      outstanding common stock prior to the business combination own more
      than 60% of the outstanding common stock of the corporation resulting
      from the business combination;

   .  no person, entity or group owns 15% or more of the outstanding voting
      securities of the corporation resulting from the
      business combination; and,

   .  at least a majority of the board of the corporation resulting from the
      business combination were members of the company's board prior to the
      business combination; or

(4) Approval by the company's stockholders of a complete liquidation or
dissolution of the company.

REPORT OF THE COMPENSATION COMMITTEE
================================================================================

The following report of the Compensation Committee shall not be incorporated by
reference into any of our prior filings under the Securities Act of 1933 or the
Securities Exchange Act of 1934 that incorporated future filings or portions
thereof (including this proxy statement or the "Executive Compensation" section
of this proxy statement), except to the

                                       13

extent that we specifically incorporate this information by reference.

The Compensation Committee is responsible for setting and overseeing the
compensation of our executive officers. The committee is composed entirely of
independent outside directors. There are no interlocking relationships between
any of our executive officers and any entity whose directors or executive
officers serve on the committee.

Objectives and Considerations

The objectives of the committee in determining executive compensation are to
retain and reward qualified individuals serving as our executive officers. To
achieve these objectives, the committee relies primarily on salary, annual
bonuses (awardable either in stock or cash) and awards under our stock option
plan. In making its decisions, the committee takes into account the conditions
within our industry, our income and cash flow and the attainment of any
designated business objectives. Individual performances are also reviewed,
taking into account the individual's responsibilities, experience and potential,
his or her period of service and current salary and the individual's
compensation level as compared to similar positions at other companies. The
committee's evaluation of these considerations is, for the most part, subjective
and, to date, it has not established any specific written compensation plans or
formulas pursuant to which the executive officers' annual compensation is
determined.

Base Salary

We do not currently have an employment agreement with any of our executive
officers. In determining the base salaries for the executive officers for 2002,
the committee relied primarily on its evaluation of the compensation being paid
to individuals holding comparable positions in the industry. In doing so, the
committee relied, to a large extent, on the results of the Mercer Energy
Compensation Survey, which surveyed the compensation and benefit programs of a
number of oil and gas related companies, one of which was us. It was the
committee's objective to set the executives' base salary at approximately the
competitive mid-range reflected in the survey. Within this range, the committee
then made any adjustments based on individual performance evaluations. Taking
these factors into consideration, the committee, with the exception of Mr.
Nikkel, decided to maintain the 2002 salaries of the named executive officers at
their 2001 level.

Bonuses

Executive officers are eligible to earn annual bonuses either in cash or in
stock. Stock bonuses are awarded pursuant to the bonus plan approved by our
stockholders on May 1, 1985 and, as amended, on May 3, 1995. The amount and type
of any bonuses awarded to executive officers is determined solely at the
subjective discretion of the committee. The committee does not base its
decisions on predetermined formulas, choosing instead to rely on its evaluation
of the various considerations set forth above. In addition, when appropriate,
bonuses are awarded to recognize short-term individual performance.

Stock Options

Stock options are granted under the stock option plan approved by our
stockholders on May 2, 1984 and, as amended, on May 3, 1989 and May 3, 1995. The
committee believes that stock options provide an incentive for the executive
officers to maximize long-term stockholder value. Stock option grants are made
at 100% of the market price on the date of grant. Generally, options become
exercisable in annual 20% increments after one year and have a ten-year life.
The number of options that are granted to an executive officer is based on the
individual's performance and level of responsibility. Option awards will vary in
size based on position level (more senior managers receive a higher multiple).
Stock options are granted to the executive officers at the discretion of the
committee. The committee's decisions with respect to awarding stock options are
generally made late each year thus allowing the committee to evaluate our annual
results as part of its decision making process.

                                       14


Chief Executive Officer

Mr. Nikkel's salary and bonus are determined by the committee substantially in
accordance with the policies described above relating to all executive officers.
Based on its review, the committee chose to raise Mr. Nikkel's 2002 salary by
5.9%.

1993 OBRA - Executive Compensation Tax Deductibility

The Internal Revenue Code, Section 162(m), limits our ability to deduct, for
federal income tax purposes, certain non-performance based compensation in
excess of $1 million per year paid to individual officers named in the

Summary Compensation Table. Based on the amount of compensation paid to each of
the named officers in fiscal 2002, it does not appear that Section 162(m) will
have a significant impact on us in the near term. However, the committee will
continue to monitor whether its executive compensation plans should be amended
to meet the deductibility requirements of the tax law.

Members of the Compensation Committee:

         John S. Zink - Chairman
         Don Cook
         John H. Williams
         J. Michael Adcock


REPORT OF THE AUDIT COMMITTEE
===============================================================================

The following report of the Audit Committee shall not be incorporated by
reference into any of our prior filings under the Securities Act of 1933 or the
Securities Exchange Act of 1934 that incorporated future filings or portions
thereof, except to the extent that we specifically incorporate this information
by reference.

The Securities and Exchange Commission rules now require that we include in our
proxy statement a report from the Audit Committee of the board. The following
report concerns the committee's activities regarding oversight of our financial
reporting and auditing process.

In accordance with its written charter, the Audit Committee of the board assists
the board in fulfilling its responsibility for oversight of the quality and
integrity of our accounting, auditing and financial reporting practices. During
the current year, the committee met three times. The committee chair, as
representative of the committee, discussed the interim financial information
contained in each quarterly earnings announcement and Form 10-Q with the CFO and
independent auditors prior to public release.

The board and the Audit Committee believe that the Audit Committee's current
member composition satisfies the rule of the New York Stock Exchange that
governs audit committee composition, including the requirement that audit
committee members all be "independent directors" as that term is defined by
applicable NYSE rule.

Management has the primary responsibility for the financial statements and the
reporting process including the systems of internal controls. In fulfilling its
oversight responsibilities, the committee reviewed the audited financial
statements in the Annual Report with management including a discussion of the
quality, not just the acceptability, of the accounting principles, the
reasonableness of significant judgments, and the clarity of disclosures in the
financial statements.

The committee reviewed with the independent auditors, who are responsible for
expressing an opinion on the conformity of those audited financial statements
with generally accepted accounting principles, their judgments as to the
quality, not just the acceptability, of our accounting principles and such other
matters as are required to be discussed with the committee under generally
accepted auditing standards, including Statement on Auditing Standards No. 61.

                                       15

The committee has discussed with the independent auditors the auditors'
independence from management, including the implications of the SEC regulations
regarding the provisions of non-audit services by the independent auditors and
determined that the provisions of the non-audit services were not inconsistent
with the independent auditors' status as independent auditors. In addition, the
committee received the written disclosures and letter from the independent
auditors required by the Independence Standards Board, Standard No. 1.

Based on the above-mentioned review and discussions with management and the
independent auditors, the committee recommended to the board that our audited
financial statements be included in its Annual Report on Form 10-K for the year
ended December 31, 2002, for filing with the Securities and Exchange Commission.

The following table sets forth the aggregate fees billed to us for the fiscal
year ended December 31, 2002 by our principal accounting firm,
PricewaterhouseCoopers L.L.P.

The Audit fees for the years ended December 31, 2002 and 2001 were for
professional services rendered for the audits of our consolidated financial
statements, limited reviews of interim financial statements, issuance of
consents and assistance with review of documents filed with the SEC.

The Audit Related fees as of the years ended December 31, 2002 and 2001 were
primarily for assurance and related services to our employee benefit plans.

The Tax fees as of the years ended December 31, 2002 and 2001 were for services
related to review of federal and state income tax returns and research and
consultation on various federal and state tax matters.

plan advisory services.

ITEM 2: RATIFICATION OF APPOINTMENT OF AUDITORS
===============================================================================

Our Audit Committee has unanimously selected PricewaterhouseCoopers LLP as our
independent auditors for our 2003 fiscal year. We are asking you to ratify and
approve this action. A representative of PricewaterhouseCoopers LLP, will attend
the annual meeting, will have the opportunity to make a statement if he or she
desires to do so and will be available to answer appropriate questions.

Although the law does not require such ratification, the Audit Committee
believes that you should be given the opportunity to express your views on this
matter. However, even if you ratify the selection, the Audit Committee may still
appoint new independent auditors at any time if it believes that such change
would be in the best interest of the company and its stockholders. Failure to
ratify such selection is not binding on the Audit Committee.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" APPROVAL,
WHICH VOTE WILL ACT TO RATIFY THE SELECTION OF PRICEWATERHOUSECOOPERS LLP.

OTHER MATTERS
===============================================================================

Certain Transactions Between the Company and Its Officers, Directors, Nominees

us and any related party, including, if applicable, those discussed above, our
board considers the terms that are or would be available to us in similar
transactions with non-affiliated parties dealing at arm's-length.

                                       18

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our
directors and officers and persons who own more than 10% of a registered class
of our equity securities to file initial reports of ownership and reports of
changes in ownership with the Securities and Exchange Commission and the New
York Stock Exchange. These persons are required by Securities and Exchange
Commission regulation to furnish us with copies of all Section 16(a) forms they
file.

Based solely on our review of the forms received by us with respect to fiscal
2002, or written representations from certain reporting persons, we believe that
each of our directors, officers and greater than 10% owners have complied with
all Section 16(a) filing requirements.

Matters Which May Come Before the Meeting

The board does not intend to bring any other matters before the meeting, nor do
we know of any matters that other persons intend to bring before the meeting.
However, should other matters not mentioned in this proxy statement properly
come before the meeting, the persons named in the accompanying proxy card will
vote on them in accordance with their best judgment.

Financial Statement and Disclosure Matters
------------------------------------------
     The Audit Committee, to the extent it deems necessary or appropriate, will:

     1. Review and discuss with management and the independent auditor the
annual audited financial statements, including disclosures made in management's
discussion and analysis, and recommend to the Board whether the audited
financial statements should be included in the Company's Form 10-K.

     2. Review and discuss with management and the independent auditor the
Company's quarterly financial statements prior to the filing of its Form 10-Q,
including the results of the independent auditors' reviews of the quarterly
financial statements.

     3. Discuss with management and the independent auditor significant
financial reporting issues and judgments made in connection with the preparation
of the Company's financial statements, including any significant changes in the
Company's selection or application of accounting principles, any major issues as
to the adequacy of the Company's internal controls, the development, selection
and disclosure of critical accounting estimates, and analyses of the effect of
alternative assumptions, estimates or GAAP methods on the Company's financial
statements.

     4. Discuss with management the Company's earnings press releases, including
the use of "pro forma" or "adjusted" non-GAAP information, as well as financial
information and earnings guidance provided to analysts and rating agencies.

     5. Discuss with management and the independent auditor the effect of
regulatory and accounting initiatives as well as off-balance sheet structures on
the Company's financial statements.

     6. Discuss with management the Company's major financial risk exposures and
the steps management has taken to monitor and control such exposures, including
the Company's risk assessment and risk management policies.

     7. Discuss with the independent auditor the matters required to be
discussed by Statement on Auditing Standards No. 61 relating to the conduct of
the audit. In particular, discuss:

        (a) The adoption of, or changes to, the Company's significant auditing
     and accounting principles and practices as suggested by the independent
     auditor, internal auditors or management.

        (b) The management letter provided by the independent auditor and the
     Company's response to that letter.

        (c) Any difficulties encountered in the course of the audit work,
     including any restrictions on the scope of activities or access to
     requested information, and any significant disagreements with management.

Oversight of the Company's Relationship with the Independent Auditor
--------------------------------------------------------------------
     8. Review the experience and qualifications of the senior members of the
independent auditor team.

     9. Obtain and review a report from the independent auditor at least
annually regarding

        (a) the auditor's internal quality-control procedures,

                                      A-2


        (b) any material issues raised by the most recent quality-control
     review, or peer review, of the firm, or by any inquiry or investigation by
     governmental or professional authorities within the preceding five years
     respecting one or more independent audits carried out by the firm,

        (c) any steps taken to deal with any such issues, and

        (d) all relationships between the independent auditor and the Company.

     Evaluate the qualifications, performance and independence of the
independent auditor, including considering whether the auditor's quality
controls are adequate and the provision of non-audit services is compatible with
maintaining the auditor's independence, and taking into account the opinions of
management and the internal auditor. The Audit Committee shall present its
conclusions to the Board and, if so determined by the Audit Committee, recommend
that the Board take additional action to satisfy itself of the qualifications,
performance and independence of the auditor.

     10. Consider whether, in order to assure continuing auditor independence,
it is appropriate to adopt a policy of rotating the lead audit partner or even
the independent auditing firm itself on a regular basis.

     11. Recommend to the Board policies for the Company's hiring of employees
or former employees of the independent auditor who were engaged on the Company's
account.

     12. Meet with the independent auditor prior to the audit to discuss the
planning and staffing of the audit.

Oversight of the Company's Internal Audit Function

executive.

responsibilities, budget and staffing and any recommended changes in the planned
scope of the internal audit.

Compliance Oversight Responsibilities
-------------------------------------
     16. Obtain from the independent auditor assurance that Section 10A of the
Securities Exchange Act of 1934 has been complied with.

     17. Obtain reports from management, the Company's senior internal auditing
executive and the independent auditor that the Company and its
subsidiary/foreign affiliated entities are in conformity with applicable legal
requirements and the Company's Code of Business Conduct and Ethics. Review
reports and disclosures of insider and affiliated party transactions. Advise the
Board with respect to the Company's policies and procedures regarding compliance
with applicable laws and regulations and with the Company's Code of Business
Conduct and Ethics.

     18. Discuss with management and the independent auditor any correspondence
with regulators or governmental agencies and establish and maintain procedures
for the confidential and anonymous receipt, retention and treatment of any
employee complaints or published reports which raise material issues regarding
the Company's financial statements or accounting policies.

     19. Discuss with the Company's General Counsel legal matters that may have
a material impact on the financial statements or the Company's compliance
policies.

Limitation of Audit Committee's Role
------------------------------------
     While the Audit Committee has the responsibilities and powers set forth in
this Charter, it is not the duty of the Audit Committee to plan or conduct
audits or to determine that the Company's financial statements and disclosures
are complete and accurate and are in accordance with generally accepted
accounting principles and applicable rules and regulations. These are the
responsibilities of management and the independent auditor.
