                          TO BE HELD ON JUNE 6, 2001

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

  The Annual Meeting of Shareholders of Comcast Corporation (the "Company")
will be held on Wednesday, June 6, 2001 at 9:00 a.m. local time at the offices
of the Company, 1500 Market Street, West Tower, 9th Floor, Philadelphia,
Pennsylvania, for the following purposes:

  1. To elect ten directors to serve for the ensuing year and until their
     respective successors shall have been duly elected and qualified.

  2. To ratify the appointment of Deloitte & Touche LLP as the Company's
     independent auditors for the 2001 fiscal year.

  3. To consider a proposal to approve the adoption of the 2001 Employee
     Stock Purchase Plan.

  4. To consider a proposal to approve an amendment to the 1996 Executive
     Cash Bonus Plan.

  5. To transact such other business as may properly come before the meeting
     or any adjournment or postponement thereof.

  The close of business on April 17, 2001 has been fixed as the record date
for the meeting. All shareholders of record at that time are entitled to
notice of, and all holders of Class A Common Stock and Class B Common Stock
are entitled to vote at, the meeting and any adjournment or postponement
thereof.

  Because holders of Class A Special Common Stock are not generally entitled
to vote and no resolution is proposed for the meeting for which a vote of the
Class A Special Common Stock is required by law, holders of Class A Special
Common Stock are not entitled to vote at the meeting. The enclosed proxy
statement is being sent to holders of Class A Special Common Stock for
informational purposes only.

  In the event that the meeting is adjourned for one or more periods
aggregating at least fifteen days due to the absence of a quorum, those
shareholders entitled to vote who attend the adjourned meeting, although
otherwise less than a quorum, shall constitute a quorum for the purpose of
acting upon any matter set forth in this notice.

  All shareholders are cordially invited to attend the meeting. The Board of
Directors urges you to date, sign and return promptly the enclosed proxy with
respect to your shares of Class A Common Stock. The proxies are solicited by
the Board of Directors of the Company. The return of the proxy will not affect
your right to vote in person if you do attend the meeting. A copy of the
Company's 2000 Financial Report is enclosed.

  The enclosed proxy is solicited by the Board of Directors of Comcast
Corporation (the "Company"), a Pennsylvania corporation, for use at the Annual
Meeting of Shareholders (the "meeting") to be held on Wednesday, June 6, 2001
at 9:00 a.m. local time at the offices of the Company, 1500 Market Street,
West Tower, 9th Floor, Philadelphia, Pennsylvania, and any adjournment or
postponement thereof. This Proxy Statement, the foregoing notice and the
enclosed proxy are being mailed to shareholders on or about May 2, 2001.

  The Board of Directors does not intend to bring any matters before the
meeting other than the matters specifically referred to in the notice of the
meeting, nor does the Board of Directors know of any matter which anyone else
proposes to present for action at the meeting. However, if any other matters
properly come before the meeting, the persons named in the accompanying proxy
or their duly constituted substitutes acting at the meeting will be deemed
authorized to vote or otherwise act thereon in accordance with their judgment
on such matters.

  When your proxy card is returned properly signed, the shares represented
will be voted in accordance with your directions. In the absence of
instructions, the shares represented at the meeting by the enclosed proxy will
be voted "FOR" each of the nominees for the Board of Directors in the election
of directors and "FOR" each of the other proposals submitted to shareholders
in accordance with the foregoing notice of meeting and as set forth in this
Proxy Statement. Any proxy may be revoked at any time prior to its exercise by
notifying the Secretary in writing, by delivering a duly executed proxy
bearing a later date or by attending the meeting and voting in person.

Voting Electronically

  Instead of submitting your vote by mail on the enclosed proxy card, the
Company's by-laws permit you to vote electronically via the Internet. Please
note that there are separate Internet voting arrangements depending on whether
shares registered in the Company's stock records are in your name or in the
name of a brokerage firm or bank.

  The Internet voting procedures are designed to authenticate shareholders'
identities, to allow shareholders to vote their shares and to confirm that
their instructions have been properly recorded. Shareholders voting via the
Internet should understand that there may be costs associated with electronic
access, such as usage charges from Internet access providers and telephone
companies, that will be borne by the shareholder.

 For Shares Registered Directly in the Name of the Shareholder

  Shareholders with shares registered directly in their name in the Company's
stock records maintained by its transfer agent, EquiServe Trust Company, N.A.
("EquiServe"), may vote their shares (1) via the Internet at the following
address on the World Wide Web: http://www.eproxyvote.com/cmcsa, (2) by mailing
their signed proxy card, or (3) by attending the meeting and voting in person.
Specific instructions to be followed by registered shareholders are set forth
on the enclosed proxy card. Votes submitted via the Internet through EquiServe
as described herein must be received by 5:00 p.m. eastern time on June 5,
2001.

                                       1


 For Shares Registered in the Name of a Brokerage Firm or Bank

  A number of brokerage firms and banks are participating in separate programs
that offer Internet voting options. Such programs are different from the
program provided by EquiServe for shares registered directly in the name of
the shareholder. If your shares are held in an account at a brokerage firm or
bank participating in any such program, you may vote those shares via the
Internet in accordance with instructions set forth on the voting form provided
to you by the brokerage firm or bank that holds your shares.

                VOTING SECURITIES AND PRINCIPAL HOLDERS THEREOF

Outstanding Shares and Voting Rights

  At the close of business on April 17, 2001, the record date, the Company had
outstanding 21,832,250 shares of Class A Common Stock, par value $1.00 per
share, 9,444,375 shares of Class B Common Stock, par value $1.00 per share,
and 913,785,165 shares of Class A Special Common Stock, par value $1.00 per
share.

  On each matter voted upon at the meeting and any adjournment or postponement
thereof, the Class A Common Stock and Class B Common Stock will vote together.
Each record holder of Class A Common Stock will be entitled to one vote per
share and each record holder of Class B Common Stock will be entitled to
fifteen votes per share. Holders of Class A Special Common Stock shall not be
entitled to vote at the meeting. References to voting classes of the Company's
Common Stock herein shall not include the Class A Special Common Stock. In the
election of directors, holders of Class A Common Stock and Class B Common
Stock shall not have cumulative voting rights.

  The presence, in person or by proxy, of shareholders entitled to cast a
majority of the votes which shareholders are entitled to cast on each matter
to be voted upon at the meeting will constitute a quorum for the meeting. In
the event that the meeting is adjourned for one or more periods aggregating at
least fifteen days due to the absence of a quorum, those shareholders entitled
to vote who attend the adjourned meeting, although otherwise less than a
quorum as described in the preceding sentence, shall constitute a quorum for
the purpose of acting upon any matter set forth in the foregoing notice of the
meeting.

  In the election of directors, the ten nominees receiving a plurality of the
votes cast at the meeting shall be elected. Approval of all other proposals to
be submitted to shareholders in accordance with the foregoing notice of the
meeting and as set forth in this Proxy Statement requires the affirmative vote
of a majority of the votes cast at the meeting. For purposes of determining
the number of votes cast with respect to any voting matter, only those cast
"FOR," "AGAINST" or, in the case of the election of directors, "WITHHELD," are
included. Abstentions and broker non-votes are counted only for purposes of
determining whether a quorum is present at the meeting.

  The holder of all of the Class B Common Stock has indicated that it will
vote all of its shares "FOR" each of the nominees for director listed below
and "FOR" each of the other proposals submitted to shareholders in accordance
with the foregoing notice of the meeting and as set forth in this Proxy
Statement. Consequently, the election of each of the nominees for director
listed below and the approval of each of the other proposals submitted to
shareholders in accordance with the foregoing notice of the meeting and as set
forth in this Proxy Statement are assured.

  The following table sets forth certain information regarding the holdings of
each shareholder who was known to the Company to be the beneficial owner, as

Act"), of more than 5% of any voting class of the Company's Common Stock
(Class A and Class B) as of February 28, 2001. So far as is known to the
Company, the persons named in the table below as beneficially owning the
shares set forth therein have sole voting power and sole investment power with
respect to such shares, unless otherwise indicated.



                                                                 Amount    Percent

(1)  As of February 28, 2001, Sural Corporation ("Sural"), a Delaware
     corporation, was the sole owner of the Company's outstanding Class B
     Common Stock and owned 136,913 shares of the Company's outstanding Class
     A Common Stock. Mr. Brian L. Roberts, President of the Company, owns
     stock representing substantially all of the voting power of all classes
     of voting securities of Sural. Pursuant to Rule 13d-3 under the Exchange
     Act, Mr. Brian L. Roberts is deemed to be the beneficial owner of the
     shares of Class B Common Stock and Class A Common Stock owned by Sural,
     and he is deemed to be the beneficial owner of 1,356 shares of Class A
     Common Stock owned by his wife, as to which he disclaims beneficial
     ownership. Since each share of Class B Common Stock is entitled to
     fifteen votes, the shares of Class A Common Stock and Class B Common
     Stock owned by Sural and Mr. Brian L. Roberts constituted as of February
     28, 2001 approximately 87% of the voting power of the two classes of the
     Company's voting Common Stock combined. The Class B Common Stock is
     convertible on a share-for-share basis into Class A Common Stock or Class
     A Special Common Stock. If Sural and Mr. Brian L. Roberts were to convert
     the Class B Common Stock that they are deemed to beneficially own into
     Class A Common Stock, Mr. Roberts would beneficially own 9,582,644 shares
     of Class A Common Stock (approximately 30.6% of the Class A Common
     Stock).

Section 16(a) Beneficial Ownership Reporting Compliance

  Section 16(a) of the Exchange Act requires the Company's executive officers
and directors and persons who own more than ten percent of a registered class
of the Company's equity securities (collectively, the "reporting persons") to
file reports of ownership and changes in ownership with the Securities and
Exchange Commission and to furnish the Company with copies of these reports.
Based on the Company's review of the copies of these reports received by it,
and written representations received from reporting persons, the Company
believes that all filings required to be made by the reporting persons for the
period January 1, 2000 through December 31, 2000 were made on a timely basis,
except for: information regarding a disposition of shares of stock by Mr.
Bonovitz, a director of the Company, in connection with sales of shares of
stock by a trust for the benefit of his children, which sales should have been
reported on a Form 4 by February 10, 2000 but were reported on a Form 5 filed
on February 13, 2001; one report regarding a disposition of shares of stock by
Mr. Watson, a director of the Company, in connection with the sale of shares
of stock, for which a Form 4 was inadvertently filed late; and one report
regarding the holdings of Lawrence J. Salva, Senior Vice President and Chief
Accounting Officer of the Company, for which a Form 3 was inadvertently filed
late.

each meeting of the Board of Directors attended and $1,000 for each meeting of
any committee of the Board of Directors attended which is not held in
conjunction with a meeting of the Board of Directors. In addition, any non-
employee director who serves as the chair of a committee of the Board of
Directors receives an annual fee of $1,000. Each director is also reimbursed
for incidental travel expenses for meetings attended.

Plan") provides that each non-employee director will be granted annually, on
each February 1, an option to purchase 5,400 shares of Class A Special Common
Stock (except that the first such grant to a new non-employee director will be
an option to purchase 9,000 shares) at an exercise price per share equal to
the fair market value of a share of Class A Special Common Stock on the date
of grant. Each such option becomes exercisable six months after the date of
grant and generally expires five years from the date

                                       8


of grant. Effective January 1, 1999, a non-employee director of the Company

Report of the Audit Committee

  The Audit Committee of the Board of Directors (the "Audit Committee") is
composed entirely of independent directors as defined in the listing standards
of the National Association of Securities Dealers. The key responsibilities of
the Audit Committee are set forth in its Charter, adopted on May 1, 2000,
which is included as Annex A to this Proxy Statement.

  The Audit Committee serves in an oversight capacity and is not intended to
be part of the Company's operational or managerial decision-making process.
The Company's management is

                                       9


responsible for preparing the Company's consolidated financial statements and
its independent auditors are responsible for auditing the consolidated
financial statements. The principal purpose of the Audit Committee is to
monitor these processes.

  In this context, the Audit Committee met and held discussions with
management and the independent auditors. Management represented to the Audit
Committee that the Company's consolidated financial statements were prepared
in accordance with generally accepted accounting principles applied on a
consistent basis, and the Audit Committee has reviewed and discussed the
consolidated financial statements with management and the independent
auditors. The Audit Committee discussed with the independent auditors matters
required to be discussed by Statement on Auditing Standards No. 61
("Communication With Audit Committees"), as amended.

  The Audit Committee discussed with the independent auditors the auditors'
independence from the Company and its management, including the matters in the
written disclosures required by the Independence Standards Board Standard No.
1 ("Independence Discussions With Audit Committees"). The Audit Committee has
also considered whether the independent auditors' provision of non-audit
related services to the Company is compatible with the auditors' independence.

  The Audit Committee discussed with the Company's internal and independent
auditors the overall scope and plans for their respective audits. The Audit
Committee met with the internal and independent auditors, with and without
management present, to discuss the results of their examinations, the
evaluations of the Company's internal controls and the overall quality of the
Company's financial reporting.

  In reliance on the reviews and discussions referred to above, the Audit
Committee recommended to the Board of Directors, and the Board has approved,
that the audited financial statements be included in the Company's Annual
Report on Form 10-K for the year ended December 31, 2000, for filing with the
Securities and Exchange Commission. The Audit Committee has recommended and
the Board has approved, subject to shareholder ratification, the selection of
the Company's independent auditors.

                                PROPOSAL THREE

                        TO APPROVE THE ADOPTION OF THE
             COMCAST CORPORATION 2001 EMPLOYEE STOCK PURCHASE PLAN

  On December 20, 2000, the Board of Directors of the Company adopted the
Comcast Corporation 2001 Employee Stock Purchase Plan (the "Stock Purchase
Plan"). The Stock Purchase Plan is intended to meet the requirements of
Section 423 of the Internal Revenue Code of 1986, as amended (the "Internal
Revenue Code"). Participants in a plan which meets the requirements of Section
423 of the Internal Revenue Code enjoy certain tax advantages, as described
below. In order for the Stock Purchase Plan to be qualified, it must be
approved by the Company's shareholders.

  The Stock Purchase Plan allows eligible employees to purchase shares of the
Company's Class A Special Common Stock at a discount without being subject to
tax until they sell the stock and without having to pay any brokerage
commissions with respect to the purchases.

  The purpose of the Stock Purchase Plan is to encourage the purchase of Class
A Special Common Stock by the Company's employees and the employees of the
subsidiaries of the Company whose participation is approved by the Board of
Directors, to provide employees with a personal stake in the Company and to
help recruit and retain employees. It is currently expected that only
employees of the Company and its wholly-owned subsidiaries Comcast Cable
Communications, Inc. and its subsidiaries and Comcast Online Communications,
Inc. will participate in the Stock Purchase Plan.

  Provided that the Company's adoption of the Stock Purchase Plan is approved
by the Company's shareholders, the first offering period under the Stock
Purchase Plan will commence on the date determined by the Board of Directors
or the Compensation Subcommittee.

Description of the Stock Purchase Plan

  The Stock Purchase Plan provides employees with the right to purchase shares
of Class A Special Common Stock through payroll deductions. A total of
4,250,000 shares of Class A Special Common Stock are available for purchase
under the Stock Purchase Plan, subject to adjustment in the number and price
of shares available for purchase if the number of outstanding shares of Class
A Special Common Stock are increased or decreased through stock dividends,
recapitalizations, stock splits, reorganizations or similar changes.

 Administration

  The Stock Purchase Plan is administered by the Compensation Subcommittee.
Subject to the terms of the Stock Purchase Plan, the Board of Directors and
the Compensation Subcommittee have authority to interpret the Stock Purchase
Plan, prescribe, amend and rescind rules and regulations relating to it and
make all other determinations deemed necessary or advisable in administering
the Stock Purchase Plan.

 Eligibility and Participation

  A full-time employee is eligible to participate in the Stock Purchase Plan
if he or she has been continuously employed for a 90-day period as of the
first day of an offering period. A part-time employee is eligible to
participate in the Stock Purchase Plan if he or she has been continuously
employed for one year as of the first day of an offering period. An employee
is considered to be a part-time employee if he or she is scheduled to work
less than 20 hours per week. If the Stock Purchase Plan had been effective as
of December 31, 2000, approximately 16,500 employees, including the

                                      11


Company's executive officers other than the Chief Executive Officer and Mr.
Brian L. Roberts, would have been eligible to participate in the Stock
Purchase Plan.

  Any eligible employee who, after purchasing shares of Class A Special Common
Stock under the Stock Purchase Plan, would own 5% or more of the total
combined voting power or value of all classes of stock of the Company or any
subsidiary corporation is not eligible to purchase additional stock under the
Stock Purchase Plan. Ownership of stock is determined in accordance with the
provisions of Section 424(d) of the Internal Revenue Code. In addition, under
the Stock Purchase Plan, the maximum fair market value of Class A Special
Common Stock an eligible employee may purchase in a calendar year is limited
to $25,000.

  Shares of Class A Special Common Stock will be available under the Stock
Purchase Plan during each offering period. The offering period will generally
be the calendar quarter. Eligible employees may elect to participate in the
Stock Purchase Plan before the start of an offering period. Shares of Class A
Special Common Stock will be deemed to have been purchased on the last day of
the offering period. The purchase price per share will be 85 percent of the
lesser of the fair market value per share of Class A Special Common Stock on
the first day of the offering period (or, if such date is not a trading day,
then on the next trading day thereafter) or the fair market value per share of
Class A Special Common Stock on the last day of the offering period (or, if
such date is not a trading day, then on the trading day immediately
preceding).

  The purchase price may also be discounted by some lesser amount than
determined above. The Board of Directors or the Compensation Subcommittee will
determine, with respect to any offering period, the amount, if any, by which
the purchase price will be discounted.

  To become a participant in the Stock Purchase Plan (for purposes of this
Proposal Three, a "Participant"), an eligible employee who wishes to
participate in the Stock Purchase Plan must file an election form at least 15
days before the beginning of an offering period. Each Participant will have
payroll deductions of not more than 10% of his or her compensation made on
each regular payday during the time he or she is a Participant in the Stock
Purchase Plan, subject to an annual limit of $10,000. All payroll deductions
will be credited to the Participant's account under the Stock Purchase Plan.

  If the total number of shares of Class A Special Common Stock for which
purchase rights are exercised at the end of an offering period exceeds the
maximum number of shares of Class A Special Common Stock available, the Board
of Directors or the Compensation Subcommittee will make a pro rata allocation
of shares available for delivery and distribution. The unapplied account
balances will be credited to Participants' accounts for the next succeeding
offering or, at the Participant's election, returned to the Participant,
without interest, as soon as practicable following the end of the offering
period.

 Termination of Participation

  A Participant may discontinue his or her participation in the Stock Purchase
Plan at any time, but no other change can be made during an offering period. A
Participant may change the amount of payroll deductions for subsequent
offerings by giving written notice of such change on or before the 15th day of
the month immediately preceding the beginning of an offering period.

  A Participant may elect to withdraw all, but not less than all, of the
balance credited to the Participant's account by providing a termination form
at any time before the end of the offering period. All amounts credited to
such Participant's account shall be paid as soon as practicable following
receipt

                                      12


of the Participant's termination form, and no further payroll deductions will
be made with respect to the Participant. A Participant who elects to withdraw
from an offering period will not be eligible to participate in the offering
period next following the date on which the Participant delivered a
termination form.

  If a Participant's employment terminates for any reason other than death,
all amounts credited to such Participant's account will be delivered to the
Participant. If a Participant's employment terminates due to death or the
Participant dies after termination of employment but before the Participant's
account has been returned, all amounts credited to such Participant's account
will be delivered to the Participant's successor-in-interest. A Participant
who is on an approved leave of absence will remain eligible to participate in
the Stock Purchase Plan through the end of the offering period that commenced
prior to such leave, unless the approved leave of absence ends and the
Participant does not return to active employment prior to the end of that
offering period.

 Method of Share Purchase

  All funds held or received by the Company under the Stock Purchase Plan may
be used for any corporate purpose until applied to the purchase of Class A
Special Common Stock or refunded to employees and shall not be segregated from
the Company's general assets. Shares of Class A Special Common Stock purchased
under the Stock Purchase Plan will be issued from the Company's treasury
shares or from authorized but unissued shares. The Company will pay all fees
and expenses incurred, excluding individual federal, state, local or other
taxes, in connection with the Stock Purchase Plan.

 Transfers of Interests

  An employee's rights under the Stock Purchase Plan belong to the employee
alone and may not be transferred or assigned to any other person during the
employee's lifetime. After shares of Class A Special Common Stock have been
issued under the Stock Purchase Plan and credited to an employee's brokerage
account under the Stock Purchase Plan, such shares may be assigned or
transferred the same as any other shares.

 Federal Income Taxation

  The Stock Purchase Plan is not qualified under Section 401(a) of the
Internal Revenue Code. The Company generally will not be entitled to a
deduction with respect to stock purchased under the Stock Purchase Plan,
unless the stock is disposed of less than one year after it is purchased by
the employee, or less than two years after the start of the offering period
pursuant to which the stock was purchased.

  Generally, no tax consequences arise at the time the Participant purchases
shares of Class A Special Common Stock under the Stock Purchase Plan. In
general, upon a disposition of shares, the Participant will receive
compensation taxable as ordinary income for the taxable year in which the
disposition occurs in an amount equal to the lesser of the excess of the fair
market value over the purchase price value of the shares at the beginning of
the offering period or the excess over the purchase price of (a) the amount
actually received for the shares if sold or exchanged or (b) the fair market
value of the shares on the date of any other termination of his or her
ownership (such as by gift). The amount of such ordinary income is then added
to the Participant's basis in his or her shares for purposes of determining
capital gain or loss. This tax treatment only applies if the Participant does
not dispose of the shares for at least one year after the date of purchase and
the Participant does not dispose of the shares for at least two years after
the beginning of the offering period pursuant to which the shares were
purchased.

  If a Participant disposes of shares of Class A Special Common Stock
purchased under the Stock Purchase Plan before the holding period is
satisfied, he or she will receive compensation taxable as ordinary income in
the amount of the difference between the amount paid for the shares and the
fair market value of the shares at the time of purchase. If the shares are
sold or exchanged, the amount of

                                      13


such ordinary income is added to the Participant's basis in his or her shares
for purposes of determining capital gain or loss.

  If a Participant dies before disposing of the shares purchased under the
Stock Purchase Plan, he or she will be deemed to have realized compensation
income taxable as ordinary income in the taxable year closing with his or her
death in an amount equal to the lesser of the excess of the fair market value
over the purchase price value of the shares at the beginning of the offering
period or the excess over the purchase price of the fair market value of the
shares on the date of death. The Participant is deemed not to have realized
any capital gain or loss because of death.

 Amendment or Termination of the Plan

  The Board of Directors or the Compensation Subcommittee has the right to
amend, modify or terminate the Stock Purchase Plan at any time without notice,
provided that, upon any termination, all shares or unapplied payroll
deductions will be distributed to Participants, and provided further, that no
amendment will affect the right of a Participant to receive his or her
proportionate interest in the shares or unapplied payroll deductions. Upon any
amendment of the Stock Purchase Plan, shareholder approval will be obtained if
required by law.

PURCHASE PLAN.

by the shareholders of the amendment to the Executive Cash Bonus Plan, the
term of the Executive Cash Bonus Plan will be extended through calendar year
2006.

  The Compensation Subcommittee, which administers the Executive Cash Bonus
Plan, determined that the extension of the Executive Cash Bonus Plan was
advisable and noted that the Company is obligated to pay cash bonuses through
the year 2006 under the terms of certain employment agreements with executive
officers. See "Executive Compensation--Agreements with Executive Officers"
below. None of the senior executives eligible under the amended Executive Cash
Bonus Plan will be entitled to receive additional benefits in excess of the
benefits he would receive under the unamended Executive Cash Bonus Plan.

  Section 162(m) of the Internal Revenue Code requires that plans such as the
Executive Cash Bonus Plan be reapproved by shareholders no less frequently
than every five years. The Executive Cash Bonus Plan was approved by
shareholders in 1997 with respect to plan years 1996-2000, and the extension
of the Executive Cash Bonus Plan through the 2003 plan year was approved by
shareholders in 1999. The Compensation Subcommittee and the Company believe
that the Executive Cash Bonus Plan is extremely useful as the Company's
principal means of providing cash incentive bonus compensation to senior
executives and that it should be extended through calendar year 2006.

Description of the Executive Cash Bonus Plan

  The following is a summary of the material features of the Executive Cash
Bonus Plan.

  The Executive Cash Bonus Plan provides for an annual cash bonus to be paid
to eligible employees of the Company (for purposes of this Proposal Four,
"Participants") selected by the Compensation Subcommittee with respect to
years from 1996 (beginning July 1, 1996) through 2003 (each, a "Plan Year").
The purpose of the Executive Cash Bonus Plan is to provide performance-based
cash bonus compensation in accordance with a formula that is based on the
financial success of the Company as part of an integrated compensation
program. The Executive Cash Bonus Plan is intended to satisfy the requirements
in Section 162(m) of the Internal Revenue Code and regulations thereunder for
"performance-based compensation" to employees subject to that provision, which
compensation is deductible by the Company even if total compensation to an
employee receiving it exceeds $1 million in any year. Upon the approval by the
shareholders of the amendment to the Executive Cash Bonus Plan described
above, the term of the Executive Cash Bonus Plan will be extended through
calendar year 2006.

  Eligibility. The Compensation Subcommittee has designated all of the
Company's named executive officers and nine additional employees, three of
whom are executive officers, as Participants in the Executive Cash Bonus Plan.
The Executive Cash Bonus Plan also provides that the Compensation Subcommittee
may from time to time designate other key executives to be included as
Participants in the Executive Cash Bonus Plan. The Compensation Subcommittee
expects that Participants in the Executive Cash Bonus Plan will be limited to
employees whose compensation is or may be subject to Section 162(m).

  Bonus Entitlement. The maximum amount of the bonus payable under the
Executive Cash Bonus Plan (the "Target Bonus") with respect to any Plan Year
is (a) 150% of the sum of a Participant's base salary and any guaranteed bonus
awarded by the Compensation Subcommittee to such Participant for such Plan
Year, plus (b) the amount, if any, by which the Participant's bonus under the
Executive Cash Bonus Plan in any prior Plan Year was less than the Target
Bonus for such prior Plan Year(s). In no event, however, can a Participant's
Target Bonus for any Plan Year exceed $3 million.

  The Executive Cash Bonus Plan requires that at the beginning of each Plan
Year the Compensation Subcommittee establish two goals for the Company's Cash
Flow (as defined in the Executive Cash Bonus Plan) for such Plan Year, a First
Tier Goal and a Second Tier Goal (which shall be higher than the First Tier
Goal). Each Participant in the Executive Cash Bonus Plan is entitled to a
bonus with respect to a Plan Year which is equal to 66 2/3% of the
Participant's Target Bonus if the Company's Cash Flow for the Plan Year is at
least equal to the First Tier Goal, and 100% of the Target Bonus if the
Company's Cash Flow for the Plan Year is at least equal to the Second Tier
Goal. If the level of Cash Flow for the Plan Year is higher than the First
Tier Goal and lower than the Second Tier Goal, the bonus with respect to such
Plan Year shall be such percentage of the Participant's Target Bonus in excess
of 66 2/3% as is determined by prorating the difference between 66 2/3% and
100%. If the level of Cash Flow for a Plan Year is below the First Tier Goal
established with respect to such Plan Year, no bonus is payable under the
Executive Cash Bonus Plan for that Plan Year.

  Each Participant shall be entitled to receive a bonus in accordance with the
Executive Cash Bonus Plan only after certification by the Compensation
Subcommittee that the performance goals have been satisfied. The bonus payment
under the Executive Cash Bonus Plan is to be paid to each Participant as soon
as practicable following the close of the applicable Plan Year.

  The Compensation Subcommittee has discretion under the Executive Cash Bonus
Plan to reduce or eliminate the bonus otherwise payable to a Participant if it
determines that such a reduction or elimination of the bonus is in the best
interests of the Company.

                                      15


  In the event any payment of a bonus otherwise payable under the Executive
Cash Bonus Plan occurs more than two months after the close of the Plan Year,
the amount of the bonus otherwise payable shall be increased by the amount
such bonus payment would earn if it were invested in an investment bearing a
7% annual rate of return, compounded daily, or such other reasonable rate of
interest as may be determined by the Compensation Subcommittee, during the
period from the close of the Plan Year with respect to which such bonus is
paid and the date the bonus is actually paid.

  "Cash Flow" is defined in the Executive Cash Bonus Plan as the operating
income before depreciation and amortization for the Company and those of its
subsidiaries which are included with the Company in its consolidated financial
statements as prepared by the Company in accordance with generally accepted
accounting principles. In the event of a significant acquisition or
disposition of any assets, business division, company or other business
operations of the Company during a Plan Year that is reasonably expected to
have an effect on Cash Flow as otherwise determined under the terms of the
Executive Cash Bonus Plan, the Executive Cash Bonus Plan provides that the
First Tier Goal and the Second Tier Goal shall be adjusted to take into
account the impact of such acquisition or disposition so as to preserve the
relationship between the Cash Flow goals for the Plan Year and the Company's
performance in the prior comparable period, on a pro forma basis giving effect
to the acquisition or disposition, as further adjusted to reflect any aspects
of the transaction that should be taken into account to ensure comparability
between amounts in the prior Plan Year and the current Plan Year.

  Administration. The Executive Cash Bonus Plan is administered by the
Compensation Subcommittee.

  Amendment and Termination of the Plan. The Executive Cash Bonus Plan may be
terminated or revoked by the Company at any time and amended by the Company
from time to time, provided that neither the termination, revocation or
amendment of the Executive Cash Bonus Plan may, without the written approval
of the Participant, reduce the amount of a bonus payment that is due, but has
not yet been paid, and provided further that no changes that would increase
the amount of bonuses determined under provisions of the Executive Cash Bonus
Plan shall be effective without approval by the Compensation Subcommittee and
without disclosure to and approval by the shareholders of the Company in a
separate vote prior to payment of such bonuses. In addition, the Executive
Cash Bonus Plan may be modified or amended by the Compensation Subcommittee,
as it deems appropriate, in order to comply with any rules, regulations or
other guidance promulgated by the Internal Revenue Service with respect to
applicable provisions of the Internal Revenue Code as they relate to the
exemption for "performance-based compensation" under Section 162(m).

  THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE "FOR"
APPROVAL OF THE AMENDMENT TO THE COMCAST CORPORATION 1996 EXECUTIVE CASH BONUS
PLAN.

(1) The Company's by-laws do not provide for the position of "Chief Executive
    Officer." For purposes of application of the proxy rules of the Securities
    and Exchange Commission to this Proxy Statement, the Company has
    determined that Mr. Ralph J. Roberts should be deemed to be the Company's
    chief executive officer.

(2) The amounts in this column include bonuses earned by the named persons
    under the Company's 1996 Executive Cash Bonus Plan, bonuses paid to the
    named persons (except Messrs. Ralph J. Roberts and Brodsky) relating to
    termination of the Company's discretionary bonus plan (see "Report on
    Executive Compensation--Compensation Related to Termination of Prior Cash
    Bonus Plan"), and guaranteed bonuses of $137,812 paid to Mr. Brian L.
    Roberts in 1998 and $6,077, $5,788 and $5,512, paid to Mr. Smith in 2000,
    1999 and 1998, respectively.

(3) This column includes Company payments to the named executive officers to
    cover their tax liabilities incurred in connection with: (a) local taxes
    on certain stock option exercises for Messrs. Brian L. Roberts and Alchin;
    (b) Company payments to Messrs. Ralph J. Roberts, Brodsky and Brian L.
    Roberts to cover the premiums attributable to the term life insurance
    portion of split-

                                      17


   dollar life insurance policies or separate term life insurance policies
   (see note (4)(b) below); (c) Company payments to cover premiums
   attributable to the executive long-term disability plan (see note (4)(d)
   below); and (d) other incidental taxable fringe benefits provided to the
   named executive officers. Such amounts are calculated based upon the amount
   of tax payable by the executive officers in accordance with the highest
   individual income tax bracket.

(4) The amounts shown in this column include benefits associated with split-
    dollar life insurance arrangements. In accordance with the terms of the
    split-dollar life insurance arrangements, the Company will recover all of
    the cumulative premiums paid by the Company for the whole-life portion of
    such policies. This column includes (with respect to amounts applicable to
    2000): (a) the dollar value, on a term loan approach, of the benefit of
    the whole-life portion of the premiums for split-dollar life insurance
    policies paid by the Company projected on an actuarial basis (Mr. Ralph J.
    Roberts, $7,417,789; Mr. Brodsky, $103,022; Mr. Brian L. Roberts, $23,578;
    Mr. Smith, $21,339; and Mr. Alchin, $20,472); (b) Company payments to
    named executive officers to cover the premiums attributable to the term
    life insurance portion of split-dollar life insurance policies or separate
    term life insurance policies (Mr. Ralph J. Roberts, $1,493,891; Mr.
    Brodsky, $61,727; Mr. Brian L. Roberts, $190,519; Mr. Smith, $1,515; and
    Mr. Alchin, $1,410); (c) Company contributions to the Comcast Corporation
    Retirement--Investment Plan in the amount of $5,950 for each of the named
    executive officers; (d) Company payments to the named executive officers
    (other than Mr. Ralph J. Roberts, who did not participate in such plan) to

    (Mr. Brodsky, $3,535; Mr. Brian L. Roberts, $4,104; Mr. Smith, $1,658; and
    Mr. Alchin, $5,938); and (e) the value, at the date of award, of
    partnership interests in a subsidiary of the Company that owns all of the
    limited partnership interests in Comcast Interactive Capital, L.P.
    ("Comcast Interactive"), an investment partnership, awarded to certain of
    the named executive officers as follows: Mr. Ralph J. Roberts, $694,118;
    Mr. Brian L. Roberts, $694,118; Mr. Smith, $555,294; and Mr. Alchin,
    $520,588, which partnership interests vest 15% on the date of award
    (February 29, 2000), 20% on each of the first through third anniversaries
    of the award, and 25% on the fourth anniversary of the award, conditioned
    upon each such executive officer's continued employment with the Company
    on the date of each such vesting. Does not include any value attributable
    to interests beneficially owned by Mr. Brodsky in the general partner of
    Comcast Interactive, as such interests were of nominal value at the time
    of acquisition. The general partner, in which the Company owns no
    interest, owns a 0.2% partnership interest in Comcast Interactive and is
    entitled to a 15% interest in the profits of Comcast Interactive, subject
    to a return of capital and a 10% preference return to the Company. Mr.
    Brodsky directs the management of Comcast Interactive.

(5) Represents the number of shares of the Company's Class A Special Common
    Stock issuable upon exercise of options. Share amounts with respect to
    options granted prior to May 5, 1999 reflect the stock split in the form
    of a dividend of one share of Class A Special Common Stock for each share
    of Class A Common Stock, Class A Special Common Stock and Class B Common
    Stock paid on May 5, 1999.

(6) Represents the number of shares of the common stock of QVC, Inc., a 57%-
    owned non-public subsidiary of the Company, issuable upon exercise of
    options granted to the named executive officers by the Compensation
    Committee of the QVC, Inc. Board of Directors on April 30, 1998, July 7,
    1998, October 26, 1998, July 7, 1999, June 21, 2000, July 17, 2000 or
    September 21, 2000 pursuant to the 1995 QVC Stock Option and Stock
    Appreciation Rights Plan (the "1995 QVC Plan"). Such options were issued
    with tandem stock appreciation rights exercisable in lieu of the options
    for 75% of the excess of the value of the QVC, Inc. common stock (as
    determined pursuant to the 1995 QVC Plan) over the exercise price of such
    options. Such options have an exercise price per share of $1,127.00 (for
    options granted on June 21, July 17 and September 21, 2000), $865.47 (for
    options granted July 7, 1999), $651.84 (for options granted July 7 and
    October 26, 1998) and $688.14 (for options granted April 30, 1998),
    representing the value of the shares underlying such options on the date
    of grant as determined pursuant to the 1995 QVC Plan, and such options
    vest

                                      18


   20% on each of the first five anniversaries of the date of grant, based on
   the named executive's continued service to the Company. In all cases,
   vesting is accelerated upon a change of control of QVC, Inc. The QVC, Inc.
   options expire ten years after the date of grant. The estimated present
   values of QVC, Inc. stock options at the date of grant which were granted
   in 2000 to Messrs. Brodsky, Brian L. Roberts and Alchin were $393,096,
   $309,933 and $567,060, respectively. Such present values are calculated
   using the Black-Scholes option pricing model, based upon the following
   assumptions used in developing the grant valuation: an expected volatility
   of approximately 20.0%; an expected term to exercise of eight years; an
   interest rate of approximately 6.2%; and no dividend yield. The actual
   value of the options, if any, realized by Messrs. Brodsky, Brian L. Roberts
   and Alchin will depend on the extent to which the market value of the
   common stock of QVC, Inc. exceeds the exercise price of the option on the
   date the option is exercised. Consequently, there is no assurance that the
   value realized by Messrs. Brodsky, Brian L. Roberts and Alchin will be at
   or near the values estimated above. During 2000, such executive officers
   exercised certain of such options to purchase shares of QVC, Inc. common
   stock and realized value upon such exercises as follows: Mr. Brodsky, 1,440
   shares, $1,040,830; Mr. Brian L. Roberts, 4,680 shares, $3,204,283; Mr.
   Smith, 800 shares, $723,160; and Mr. Alchin, 600 shares, $569,970. At
   December 31, 2000, the number of shares of QVC, Inc. common stock
   underlying unexercised options was as follows: Mr. Brodsky (0 exercisable,
   1,760 unexercisable); Mr. Brian L. Roberts (0 exercisable, 7,400
   unexercisable); Mr. Smith (1,000 exercisable, 1,400 unexercisable); and Mr.
   Alchin (480 exercisable, 1,920 unexercisable). At December 31, 2000, the
   excess of the fair market value of QVC, Inc. common stock over the exercise
   price for options outstanding based upon the most recent valuation date was
   as follows: Mr. Brodsky ($0 exercisable, $577,946 unexercisable); Mr. Brian
   L. Roberts ($0 exercisable, $3,356,635 unexercisable); Mr. Smith ($539,476
   exercisable, $756,428 unexercisable); and Mr. Alchin ($253,373 exercisable,
   $486,859 unexercisable).

--------
*   Less than one percent of total options granted to employees in 2000.

                                      19


(1)  All of the options are for the purchase of shares of Class A Special
     Common Stock and were granted on either January 4, March 30, June 2, July
     5 or October 5, 2000 under the Company's 1996 Stock Option Plan. Except
     as described in note (3) below, all options granted in 2000 have exercise
     prices equal to the fair market value of the underlying stock on the date
     of grant and generally become exercisable at the rate of 20% of the
     shares covered thereby on the second anniversary of the date of grant,
     another 10% on each of the third through ninth anniversaries of the date
     of grant and 10% six months prior to the tenth anniversary of the date of
     grant, or, as to 247,165 stock options granted to Mr. Ralph J. Roberts on
     March 30, 2000, 1,000,000 stock options granted to Mr. Brian L. Roberts
     on January 4, 2000 and 1,000,000 stock options granted to Mr. Brian L.
     Roberts on October 5, 2000, at the rate of 40% of the shares covered
     thereby on the second anniversary of the date of the grant and 20% each
     on the third, fourth and fifth anniversaries of the date of the grant.
     All options granted are nonqualified stock options, except for 2,835 of
     the options granted to Mr. Ralph J. Roberts, 2,597 of the options granted
     to Mr. Brodsky, 2,909 of the options granted to Mr. Brian L. Roberts and
     2,662 of the options granted to each of Messrs. Smith and Alchin, which
     are incentive stock options. With respect to the grant of options to
     purchase 1,000,000 shares made to Mr. Brian L. Roberts effective October
     5, 2000, such options shall automatically convert to and become options
     to purchase shares of the Company's Class B Common Stock in the event and
     at such time as the shareholders may approve an amendment to the 1996
     Stock Option Plan permitting such conversion.

(2)  These amounts represent the estimated present value of stock options at
     the date of grant calculated using the Black-Scholes option pricing
     model, based upon the following assumptions used in developing the grant
     valuations: an expected volatility of approximately 35.8%; an expected
     term to exercise of eight years, except for certain incentive stock
     options granted to Messrs. Ralph J. Roberts and Brian L. Roberts, for
     which the expected term to exercise is five years; an interest rate of
     approximately 6.4%; and no dividend yield. The actual value of the
     options, if any, realized by an executive officer will depend on the
     extent to which the market value of the Class A Special Common Stock
     exceeds the exercise price of the option on the date the option is
     exercised. Consequently, there is no assurance that the value realized by
     an executive officer will be at or near the value estimated above. These
     amounts should not be used to predict stock performance.

(3)  In accordance with the tax rules governing incentive stock options, these
     options were granted at an exercise price equal to 110% of the fair
     market value of the underlying stock on the date of grant. The options to
     purchase shares of the Company's Class A Special Common Stock become
     exercisable at the rate of 40% of the shares covered thereby on the
     second anniversary of the date of grant, another 20% on each of the third
     and fourth anniversaries of the date of grant and another 20% six months
     prior to the fifth anniversary of the date of grant.

(4)  In addition to the options described above, (i) on July 17, 2000, options
     to purchase 640 shares of the common stock of QVC, Inc. at an exercise
     price of $1,127.00 per share were issued to Mr. Brian L. Roberts; (ii) on
     June 21, 2000, options to purchase 800 shares of the common stock of QVC,
     Inc. at an exercise price of $1,127.00 per share were issued to Mr.
     Brodsky; and (iii) on September 21, 2000, options to purchase 1,200
     shares of the common stock of QVC, Inc. at an exercise price of $1,127.00
     per share were issued to Mr. Alchin. See note (6) under "Executive
     Compensation--Summary Compensation Table."

--------
(1)  Mr. Ralph J. Roberts realized the value shown above upon the exercise of
     options to purchase 1,229,561 shares of Class A Special Common Stock. In
     addition, the receipt of 809,968 shares of Class A Special Common Stock
     to be issued to Mr. Ralph J. Roberts was deferred until July 15, 2002
     pursuant to the Company's 1997 Deferred Stock Option Plan (the "Deferred
     Stock Option Plan"), resulting from the exercise on June 1, 2000 of
     options to purchase 1,111,516 shares at an exercise price of $9.5625 per
     share, net of 20,917 shares withheld to satisfy certain tax obligations.
     The per share fair market value of such shares on June 1, 2000 was
     $37.875. The value ultimately realized with respect to such shares will
     be determined based on the fair market value of such shares upon their
     issuance to Mr. Ralph J. Roberts. If such shares (and such withheld
     shares) had been issued to Mr. Ralph J. Roberts on the date of exercise,
     the aggregate value realized by him with respect to such exercise would
     have been $31,469,797.

     Table."

(3)  Represents 408,516 shares of Class A Special Common Stock to be issued to
     Mr. Brodsky, the receipt of which has been deferred until January 1, 2003
     pursuant to the Deferred Stock Option Plan, resulting from the net
     exercise on June 20, 2000 of options to purchase 296,541 shares at an
     exercise price of $5.4167 per share and options to purchase 222,660
     shares at an exercise price of $9.5625 per share, net of 11,403 shares
     withheld to satisfy certain tax obligations. The per share fair market
     value of such shares on June 20, 2000 was $37.625. The value ultimately
     realized with respect to such shares will be determined based upon the
     fair market value of such shares upon their issuance to Mr. Brodsky. If
     such shares (and such withheld shares) had been issued to Mr. Brodsky on
     the date of exercise, the aggregate value realized by him with respect to
     such exercises would have been $15,799,478.

Pension Plan

  Under the Company's Supplemental Executive Retirement Plan (the
"Supplemental Executive Retirement Plan"), adopted July 31, 1989, supplemental
retirement, death and disability benefits may be paid to or in respect of
certain senior executives employed by the Company and its affiliated
companies, as selected by the Company's Board of Directors. The Supplemental
Executive Retirement Plan contemplates the payment of various percentages of a
participant's Final Average Compensation (as actuarially reduced, in certain
circumstances, and as defined below) in the event that the participant (i)
elects to retire early (after the later of the participant's 55th birthday or
20 years of service with the Company); (ii) retires at age 65 or after; (iii)
suffers a permanent disability which

                                      21


renders the participant incapable of employment in the same or a similar
occupation; or (iv) dies. A participant may elect a reduction in lifetime
benefits in exchange for the continuation of payments to a surviving spouse.
As of the date of this Proxy Statement, Messrs. Ralph J. Roberts and Brodsky
(who are each credited with 30 years of service, the maximum credited service
allowed under the Supplemental Executive Retirement Plan) are the only current
employees selected by the Board of Directors to participate in the
Supplemental Executive Retirement Plan.

  The following table shows the annual single life annuity retirement benefit
which Messrs. Ralph J. Roberts and Brodsky, respectively, would receive based
on remuneration covered by, and years of service credited under, the
Supplemental Executive Retirement Plan if he had retired on January 1, 2001 at
age 65 (or older). The benefits shown below are subject to reduction for
Social Security benefits.

(1) Final Average Compensation equals one-fifth of the total compensation for
    the five years preceding termination of employment. Compensation includes
    salary, bonus (including any deferred bonus) and any other supplementary
    remuneration, but excludes payments made to participants for split-dollar
    life insurance premium bonuses and payments made to offset tax liabilities
    incurred related to these bonuses. In the case of Mr. Ralph J. Roberts,
    Final Average Compensation may, under some circumstances, be increased as
    described in "Agreements with Executive Officers--Compensation Agreement
    with the Chief Executive Officer--Election to Become a Consultant," below.

(2) This column represents the maximum benefits payable under the Supplemental
    Executive Retirement Plan.

  The Company also has an agreement with Mr. Brodsky pursuant to which he is
entitled to a $30,000 payment each year for 15 years commencing upon his
termination of employment, subject to a vesting schedule. Any benefits
received under this agreement reduce the benefits to which Mr. Brodsky is
entitled under the Supplemental Executive Retirement Plan.

Agreements with Executive Officers

 Compensation Agreement with the Chief Executive Officer

  A Compensation and Deferred Compensation Agreement and Stock Appreciation
Bonus Plan with the Chief Executive Officer (the "1993 Compensation
Agreement") was approved by the Company's shareholders on June 22, 1994.
Certain terms of the 1993 Compensation Agreement expired on December 31, 1997,
and on December 16, 1997 the Company and the Chief Executive Officer entered
into a new Compensation and Deferred Compensation Agreement. This agreement
was amended and restated effective August 31, 1998, and then amended again
effective August 30, 1999 (as so amended, the "1998 Compensation Agreement").
The 1998 Compensation Agreement generally extends the terms of the 1993
Compensation Agreement with certain modifications.

                                      22


  The 1998 Compensation Agreement provides that the Chief Executive Officer
will continue to serve as Chairman of the Board of Directors of the Company
until December 31, 2002, or until such time as he may elect to change his
status to that of a non-executive consultant, and that until he makes such
election he will continue to devote substantially all of his working time to
the Company, on the terms and conditions summarized below. If he elects to
become a non-executive consultant, he shall devote such time as is necessary
to perform the functions reasonably requested by the Company. In addition, for
a period of five years following any termination of the service period of the
1998 Compensation Agreement, the Chief Executive Officer will perform such
reasonable ceremonial functions as the Company may request, and will promote
the interests and goodwill of the Company in such manner as the Company may
reasonably request.

  Base Salary. The 1998 Compensation Agreement provides that the Chief
Executive Officer will receive an annual base salary of $1 million beginning
in 1998, as adjusted (but never reduced, except pursuant to an overall plan to
reduce the compensation of all senior executive officers of the Company) in
order to reflect the greater of increases in the consumer price index
subsequent to 1997 and the average percentage increase in the base
compensation of the five employees of the Company (other than the Chief
Executive Officer) with the highest base compensation.

  Bonus. The 1998 Compensation Agreement provides that so long as he continues
to serve as an executive of the Company the Chief Executive Officer will be
eligible to receive annual bonuses of up to 50% of his base salary in
accordance with the Company's Executive Cash Bonus Plan, based on performance
targets established by the Compensation Subcommittee.

  Split-Dollar Life Insurance. The 1998 Compensation Agreement requires the
Company to continue to provide and to maintain the split-dollar life insurance
provided to the Chief Executive Officer under the 1993 Compensation Agreement,
and in addition to provide additional survivorship split-dollar life insurance
to the Chief Executive Officer and his spouse. Such split-dollar life
insurance includes certain split-dollar life insurance provided pursuant to
the 1993 Compensation Agreement to replace the potential benefits represented
by the Company's terminated discretionary bonus plan with respect to the
appreciation through March 15, 1994, in the options for Class A Special Common
Stock previously awarded to the Chief Executive Officer, taking into account
the financial position of the Company and the tax deductibility of any such
payments. See "Report on Executive Compensation--Compensation Related to
Termination of Prior Cash Bonus Plan" below. Under the split-dollar life
insurance arrangements, the Company pays a portion of the annual premiums for
certain single-life and joint-and-survivor life insurance policies for the
Chief Executive Officer, and upon payment of the policies at the death of the
Chief Executive Officer or of the survivor of the Chief Executive Officer and
his spouse, as applicable, the Company recovers all of the cumulative premiums
previously paid by the Company for the whole-life portion of such policies.
The Chief Executive Officer is responsible for payment of the portion of such
annual premiums representing the cost of term insurance for each year. The
Company also pays the Chief Executive Officer an annual cash bonus in an
amount equal to the portion of the annual premium for such life insurance that
he is required to pay; in addition, the Company increases the bonus by an
amount sufficient to pay any income tax and gift tax liability incurred or to
be incurred in connection with payment of the bonus.

  Supplemental Death Benefit. Upon the death of the Chief Executive Officer,
the 1998 Compensation Agreement requires the Company to pay a supplemental
death benefit (the "Death Benefit") to the personal representatives of the
Chief Executive Officer. The amount of the Death Benefit was initially $31.2
million. The 1998 Compensation Agreement substituted the Death Benefit for two
bonus arrangements included in the 1993 Compensation Agreement that were based
on appreciation of the Company's Class A Common Stock from the date of grant
of options to purchase Class B Common Stock to the date of exercise. The
Compensation Subcommittee determined that the after-tax present value cost to
the Company of the Death Benefit was approximately equal to the cost of the
bonuses that would otherwise have been paid. The Company must pay the Death
Benefit within

                                      23


six months from the date of the Chief Executive Officer's death. Under the
terms of the 1998 Compensation Agreement, the Chief Executive Officer may
request that the Company invest portions of the Death Benefit in certain
investments identified by the Chief Executive Officer. Should the Company
choose to comply with the Chief Executive Officer's request, the amount of the
Death Benefit will be adjusted to reflect the increase or decrease in value of
any such investments.

  Termination. The 1998 Compensation Agreement will terminate upon the Chief
Executive Officer's death, at the Company's option upon his disability, or for
cause (as such terms are defined in the 1998 Compensation Agreement) upon a
vote of not less than two-thirds of the entire membership of the Company's
Board of Directors. If his employment is terminated by reason of his death or
disability, the Company shall continue to pay his annual base salary on a
monthly basis to him or his spouse, during their lifetimes, for a maximum of
five years, and the Accrued Cash Bonus, the Benefit Plans (as such terms are
defined in the 1998 Compensation Agreement) and the Death Benefit will
continue to be payable. In the event of death, all of his outstanding stock
options will vest fully and remain exercisable for their remaining terms. If
his employment is terminated by the Company in violation of the 1998
Compensation Agreement, he shall remain entitled to substantially all of the
benefits under the 1998 Compensation Agreement.

  Noncompetition and Confidentiality. Under the 1998 Compensation Agreement,
the Chief Executive Officer has agreed not to compete with the Company during
his employment and for five years after termination of his employment. The
agreement also requires him to maintain the confidentiality of certain
information of the Company, and not to use such information except for the
benefit of the Company, at all times during his employment and after
termination of his employment. Breach of any of such obligations constitutes
cause for termination of the 1998 Compensation Agreement and terminates the
Company's obligations for payments subsequent to any discharge of the Chief
Executive Officer.

  Change of Control Provisions. Prior to any "Change of Control" (as defined
below), the Company must establish and fund a grantor trust, the amounts in
which will be subject to claims of the Company's creditors in the case of the
Company's bankruptcy, for the purpose of paying all deferred compensation,
nonqualified retirement benefits, and split-dollar life insurance premiums and
bonuses for the Chief Executive Officer then applicable. Upon the occurrence
of a Change of Control, such trust must become irrevocable (if not already
irrevocable), and the Company must continue to make payments into such trust
to maintain sufficient amounts therein to fund all benefits subject to the
trust. A "Change of Control" is defined as occurring when persons other than
the Chief Executive Officer and members of his immediate family or trusts for
their benefit acquire voting power over more than 50% of the voting stock of
the Company.

  Election to Become a Consultant. The Chief Executive Officer may at any
time, upon 30 days notice to the Company, elect to change his position from
that of an executive to that of consultant to the Company. In such event, he
shall continue to receive all of the compensation provided under the 1998
Compensation Agreement, other than the bonus under the Executive Cash Bonus
Plan. If he elects to become a consultant, the Chief Executive Officer's
entitlement to retirement benefits under the Company's Supplemental Executive
Retirement Plan will be adjusted annually to reflect 150% of his base salary
as a consultant, but his benefits under such plan will not in any event exceed
the bonus he could have received under the 1998 Compensation Agreement had he
continued to work as an executive.

 Compensation Agreement with Mr. Brian L. Roberts

  The Company entered into a Compensation Agreement (the "Compensation
Agreement") with Brian L. Roberts, the Company's President. The following is a
description of the material terms of the Compensation Agreement.

                                      24


  Term. The term of the Compensation Agreement is from June 16, 1998 through
June 30, 2003 (the "Employment Period"). Mr. Brian L. Roberts agrees to work
full time for the Company during the Employment Period.

  Base Salary. The Compensation Agreement provides that Mr. Brian L. Roberts
will receive an annual base salary of $1 million beginning in 1998, as
adjusted (but never reduced, except pursuant to an overall plan to reduce the
compensation of all senior executive officers of the Company) from time to
time to reflect his contribution to the growth and success of the Company.

  Bonus; Options. Pursuant to the Compensation Agreement, Mr. Brian L. Roberts
is eligible to receive an annual performance bonus, payable in cash,
commencing in 1999, of up to 150% of his base salary for the applicable year.
The amount of the bonus is determined annually by the Compensation
Subcommittee, in accordance with, and upon satisfaction of, the standards
contained in the Company's Executive Cash Bonus Plan. The Compensation
Agreement also provides that Mr. Brian L. Roberts is to receive grants of
options to purchase 3,000,000 shares of Class A Special Common Stock of the
Company granted effective June 16, 1998 and options to purchase 1,000,000
shares of Class A Special Common Stock of the Company granted effective the
second business day of each fiscal quarter in 1999 and 2000, or such earlier
date as the Compensation Subcommittee may determine in its sole discretion.

  Deferred Compensation. The Compensation Agreement provides that the Company
and Mr. Brian L. Roberts may, by written agreement prior to the end of any
calendar year during the Employment Period, cause the payment of all or a
portion of the compensation payable to Mr. Brian L. Roberts in the subsequent
calendar year to be deferred to a subsequent calendar year in accordance with
and subject to the Company's 1996 Deferred Compensation Plan.

  Termination. The Compensation Agreement will terminate upon the death of Mr.
Brian L. Roberts, at the Company's option upon his disability, or for cause
(as such terms are defined in the Compensation Agreement) upon a vote of not
less than two-thirds of the entire membership of the Company's Board of
Directors. If his employment is terminated by reason of his death or
disability, the Company shall continue to pay his annual base salary on a
monthly basis to him or his spouse, during their lifetimes, for a maximum of
five years, and the accrued cash bonus as provided for in the Compensation
Agreement and any applicable health plan benefits will continue to be payable.
If his employment is terminated by the Company in violation of the
Compensation Agreement, he shall remain entitled to substantially all of the
benefits under the Compensation Agreement.

  Noncompetition and Confidentiality. Under the Compensation Agreement, Mr.
Brian L. Roberts agrees not to compete with the Company during his employment
and for two years after termination of his employment. The Agreement also
requires him to maintain the confidentiality of certain information of the
Company, and not to use such information except for the benefit of the
Company, at all times during his employment and after termination of his
employment. Breach by Brian L. Roberts of any of such obligations constitutes
cause for termination of the Compensation Agreement, and terminates the
Company's obligations for payments subsequent to such termination.

  Change of Control Provisions. Prior to any "Change of Control" (as defined
below), the Company must establish and fund a grantor trust, the amounts in
which will be subject to claims of the Company's creditors in the case of the
Company's bankruptcy, for the purpose of paying all deferred compensation and
term life insurance premiums and bonuses for Mr. Brian L. Roberts then
applicable. Upon the occurrence of a Change of Control, such trust must become
irrevocable (if not already irrevocable), and the Company must continue to
make payments into such trust to maintain sufficient amounts therein to fund
all benefits subject to the trust. A "Change of Control" is defined as
occurring when persons other than Mr. Brian L. Roberts and members of his
immediate family or trusts for their benefit acquire voting power over more
than 50% of the voting stock of the Company.

 Term Life Insurance Agreement with Mr. Brian L. Roberts

  The Company has entered into a Term Life Insurance Premium and Tax Bonus
Agreement dated as of September 23, 1998 (the "Term Life Insurance Agreement")
with Mr. Brian L. Roberts, the Company's President. The Term Life Insurance
Agreement provides that, as additional compensation to Mr. Brian L. Roberts,
the Company will reimburse him for all of the premiums on certain specified
20- and 15-year level-premium term life insurance policies aggregating $170
million in insurance on his life, and that the Company will pay him an
additional bonus equal to the income tax payable on such reimbursement and the
bonus. The annual amount of the premiums to be reimbursed under the Term Life
Insurance Agreement is approximately $189,000 through 2012 and $177,000 from
2013 through 2017.

  The Term Life Insurance Agreement provides that prior to any "Change of
Control" (as defined below), the Company must establish a grantor trust, the
amounts in which will be subject to claims of the Company's creditors in the
case of the Company's bankruptcy, for the purpose of paying all premium
reimbursements and tax bonuses for the remaining life of the policies subject
to the Term Life Insurance Agreement. Upon the occurrence of a Change of
Control, such trust must become irrevocable (if not already irrevocable), and
the Company must make payments into such trust in an amount equal to the full
amount required to be paid during the remaining term of the insurance
policies. A "Change of Control" is defined as occurring when persons other
than Mr. Brian L. Roberts and members of his immediate family or trusts for
their benefit acquire voting power over more than 50% of the voting stock of
the Company. The Term Life Insurance Agreement does not terminate upon
termination of the employment of Mr. Brian L. Roberts by the Company.

 Employment Agreements with Messrs. Smith and Alchin

  The Company has entered into employment agreements with two other named
executive officers of the Company: Lawrence S. Smith, the Company's Executive
Vice President, and John R. Alchin, the Company's Executive Vice President and
Treasurer. The following is a description of the material terms of such
agreements.

  The term of each such agreement is from May 31, 2000 through December 31,
2005 (the "Executive Employment Period"). Mr. Smith and Mr. Alchin each agree
to work full time for the Company during the Executive Employment Period.

  The agreement with Mr. Smith provides for a base salary of $825,000 in 2001,
and the agreement with Mr. Alchin provides for a base salary of $700,000 in
2001. In each case, for each year in the Executive Employment Period
subsequent to 2001 the base salary is increased by the greater of 5% or the
percentage increase during the previous year in the consumer price index.

  Pursuant to the agreements, each of the executives is eligible to receive an
annual performance bonus, commencing in 2000, of up to 50% of his base salary
for the applicable year. The amount of the bonus is determined annually by the
Compensation Subcommittee, based on the performance of the Company and of the
executive during such year, and is payable in cash or in shares of Class A
Special Common Stock of the Company, at the discretion of the Compensation
Subcommittee.

  Each agreement provides that the executive's employment may be terminated
without cause by the Company and that he may resign voluntarily. If the
executive's employment is terminated without cause, he is entitled to receive
his then-current base salary and all insurance, medical or other similar
benefits for a period of two years from the date of discharge, subject to
offset by other compensation or benefits earned by the executive during such
period, and he is entitled to receive his bonus for the year of discharge. If
the executive resigns, or is terminated for cause (as defined in the
agreement), he is entitled only to his base salary for days actually worked
and any amounts due to him under the Company's 1996 Deferred Compensation
Plan.

                                      26


  Under each of the agreements, the executive agrees not to compete with the
Company during his employment and for one year after termination of his
employment. The agreements also require each executive to maintain the
confidentiality of certain information of the Company, and not to use such
information, except for the benefit of the Company, at all times during his
employment and after termination of his employment. Breach by the executive of
any of such obligations constitutes cause for termination of the applicable
agreement, and terminates the Company's obligations for payments subsequent to
any discharge of the executive. Each of the agreements provides that it shall
continue in effect upon the merger of the Company into another entity, or in
similar events.

Report on Executive Compensation

  This report is issued jointly by the Compensation Committee of the Board of
Directors (the "Committee") and the Compensation Subcommittee. The Committee
is generally responsible for making broad recommendations to the Board of
Directors on executive compensation. However, authority on virtually all
specific compensation decisions for the Company's executive officers has been
delegated to the Compensation Subcommittee, including matters such as
establishing performance-based criteria and goals for compensation to senior
executives and for administering the Company's 1987 Stock Option Plan, 1996
Stock Option Plan, 1990 Restricted Stock Plan, Executive Cash Bonus Plan and
other bonus plans, and for approval of agreements with the Chief Executive
Officer, as well as Mr. Brian L. Roberts and others. The members of the
Compensation Subcommittee (which, for the 2000 fiscal year, included Gustave
G. Amsterdam, who died in early 2001) are disinterested non-employee directors
as well as "outside directors" (as defined in Section 162(m) of the Internal
Revenue Code).

  Compensation Policy. The goal of the Committee and the Compensation
Subcommittee is to attract and retain highly qualified executive officers and
key employees in an effort to enhance shareholder value. The Company attempts
to realize this goal by providing competitive compensation and permitting
executive officers to take an ownership stake in the Company commensurate with
their relative levels of seniority and responsibilities.

  The Committee performs a general review each year of the Company's executive
compensation. A key factor in the assessment of the compensation of the
Company's executive officers is the Company's overall performance, in light of
their principal responsibility for overall corporate policy-making, management
and administration. However, the compensation of the Company's executive
officers, including the Chief Executive Officer, is primarily determined
pursuant to multi-year contracts and the Executive Cash Bonus Plan. Therefore,
the Compensation Subcommittee primarily reviews each executive officer's
compensation in connection with modifications or renewals of the executive's
employment contract. The current compensation structure for the named
executive officers (other than the Chief Executive Officer) resulted from a
comprehensive review of the compensation package of the Company's President
and the overall structure of the Company's incentive compensation programs for
all executive employees, which culminated in the Compensation Subcommittee's
authorization and direction to management in early 2000 to seek to enter into
five-year employment agreements containing non-competition provisions with all
executive officers.

  The principal forms of executive compensation used by the Company in recent
years are base salary, bonuses, stock options, and, for certain executives,
split-dollar (whole) life insurance policies and term insurance policies. The
Company seeks to achieve a mix of these various forms of compensation which
will properly compensate and motivate its executives on an individual basis
commensurate with their relative levels of seniority and responsibility. A
variety of factors are considered in arriving at the compensation paid to the
Company's executive officers. No specific weighting was assigned to any of the
factors considered in determining the remuneration paid to the named executive
officers for 2000. Prior to seeking to enter into five-year employment
agreements in the year 2000 (as noted above), the Committee's general goal had
been to provide the executive officers (other than the Chief Executive
Officer) with total compensation that, based on individual and Company
performance viewed over an appropriate period of time, was generally between
the 50th and 75th percentile of total compensation for executives with
comparable positions at peer companies, as confirmed by an independent
compensation consultant. The employment agreements signed by executive
officers in the year 2000 did not alter this approach substantially. However,
in the case of the Chief Executive Officer, compensation has historically been
determined, as discussed below, by individualized assessment of his
performance and by comparison to executives of other companies who have been
"founders" (i.e., the persons most responsible for extraordinary growth and
success at their companies, regardless of industry). The Committee believes
that the Company's most direct

                                      28


competitors for executive talent are composed of a broader range of companies
than those with which the Company would ordinarily be compared for stock
performance purposes. Thus, the compensation comparison group included
companies that are not included in the peer group index in the stock
performance graph above.

  Base Salary. The Company's philosophy with respect to setting base salary is
to compensate its executive officers with reasonable current income on a
competitive basis. The base salary of the Chief Executive Officer increased by
5% in 2000 pursuant to the terms of the 1998 Compensation Agreement. The base
salaries of Messrs. Brian L. Roberts, Brodsky, Smith and Alchin were increased
by 5% each in 2000. The base salaries of Messrs. Smith and Alchin were
increased pursuant to the terms of their employment agreements with the
Company in effect at the beginning of 2000, and, as of January 1, 2001, the
salaries of Messrs. Smith and Alchin were further increased in accordance with
their employment agreements effective May 31, 2000. In entering into
employment agreements with Messrs. Smith and Alchin in 2000, the Compensation
Subcommittee considered its assessment of their performance, achievements and
increased responsibilities over the past decade.

  Bonuses. Since 1996, annual cash bonuses for executive officers are
primarily determined under the shareholder-approved Executive Cash Bonus Plan.
Under the Executive Cash Bonus Plan, each executive designated by the
Compensation Subcommittee is eligible to earn an annual bonus of up to 150% of
his base salary and guaranteed bonus (the percentage applicable to each
executive as determined by the Compensation Subcommittee), but not more than
$3 million, based on annual Cash Flow performance targets established in
advance by the Compensation Subcommittee. Based on the Company's Cash Flow for
such period, 100% of the Target Bonuses were earned for 2000 under the plan.
The Target Bonus for each of the named executive officers was based on the
advice of an independent compensation consultant and the Compensation
Subcommittee's assessment of the optimal mix of base and incentive cash
compensation.

  The Executive Cash Bonus Plan was adopted based on the recommendation of the
Company's independent compensation consultant and to satisfy the terms of the
Company's employment agreements then in effect with Messrs. Smith and Alchin.
The Compensation Subcommittee selected increases in Cash Flow as the single
most significant measure of operating performance of the Company and other
companies in the Company's industries.

  The named executive officers (other than the Chief Executive Officer and Mr.
Brodsky) also earned certain other bonuses in 2000 which were related to the
termination of a prior cash bonus plan, as discussed below.

  Equity-Based Incentive Compensation. The Company's equity-based incentive
compensation is in the form of stock option grants. The Compensation
Subcommittee believes that reliance upon such incentives is advantageous to
the Company because it fosters a long-term commitment by the recipients to the
Company and motivates these executives to seek to improve the long-term market
performance of the Company's stock. Stock options produce value to executives
only if the price of the Company's stock appreciates, thereby directly linking
the interests of the executives with those of the Company's shareholders.

  The Compensation Subcommittee awarded stock options in 2000 to each of the
named executive officers. In general, such option grants were based on a
proportional relationship to the expected cash compensation of the option
recipients, taking into account prior option grants and grants made at the
same time to other executives of the Company. As provided in the Compensation
Agreement, and as supported by the recommendation of its independent
compensation consultant and its review of Mr. Brian L. Roberts' achievements
on behalf of the Company over the five years prior to such time, Mr. Brian L.
Roberts received in 2000 grants of options to purchase an aggregate of
4,000,000 shares of the Company's Class A Special Common Stock. See
"Agreements with Executive Officers--

                                      29


Compensation Agreement with Mr. Brian L. Roberts." However, with respect to
the grant of options to purchase 1,000,000 shares made effective October 5,
2000, such options shall automatically convert to and become options to
purchase shares of the Company's Class B Common Stock in the event and at such
time as the shareholders may approve an amendment to the 1996 Stock Option
Plan permitting such conversion. In determining that such options could
convert to and become options to purchase shares of the Company's Class B
Common Stock, the Compensation Subcommittee noted that the transition of
control over the Class B Common Stock in 1997 from the Chief Executive Officer
to Mr. Brian L. Roberts had served the Company well and that there were
continuing significant benefits to the Company from the control by the Roberts
family over the vote of the Class B Common Stock. The Committee and the
Compensation Subcommittee determined that awarding options to purchase Class B
Common Stock would encourage Mr. Brian L. Roberts to retain such stock once
the options were exercised. The option grants to Messrs. Smith and Alchin were
awarded in connection with the execution by such executive officers of their
new employment agreements with the Company, and were generally based on a
proportional relationship to their expected cash compensation and were
consistent with options granted at the same time to other members of senior
management of the Company.

  Equity Ownership Policy. The Company's Board of Directors has maintained a
minimum equity ownership policy since 1998, applicable to substantially all
executives of the Company with base salaries in excess of $150,000, as well as
to directors. Executives and directors subject to the policy may not sell
shares of common stock of the Company unless, following such sale, they
continue to own at least an amount of the common stock with a value equal to a
multiple of their annual base compensation from the Company. The Chief
Executive Officer, as well as Mr. Brian L. Roberts, the Company's President,
and all non-employee directors, are required to own stock with a value of five
times base compensation; other executives are required to own stock with a
value of one and one-half to four times their base compensation, depending on
base compensation. Based on their current base compensation, each of the other
named executive officers is required under the policy to own Company stock
with a value of between three and one-half and four times his base
compensation. For purposes of the policy, stock owned by an applicable
person's spouse and children, stock owned pursuant to the Company's 1997
Deferred Stock Option Plan and 60% of the value of an applicable person's
vested in-the-money stock options are considered owned by the applicable
person. In addition, upon the approval by the shareholders of the 2001
Employee Stock Purchase Plan, shares of stock purchased pursuant to the terms
of the 2001 Employee Stock Purchase Plan and held in a broker's account will
be considered owned by the applicable person. The Compensation Subcommittee
believes that such policy serves to align more fully the interests of
management under the Company's equity-based incentive compensation programs
with the interests of the Company's shareholders.

  Compensation of Chief Executive Officer. The Company's by-laws do not
provide for a "Chief Executive Officer" of the Company. The Company has
determined that, for 2000, Mr. Ralph J. Roberts, the Chairman of the Company's
Board of Directors, was its chief executive officer for purposes of this Proxy
Statement.

  The Chief Executive Officer's compensation for 2000 was determined under the
terms of the 1993 Compensation Agreement and the 1998 Compensation Agreement.
See "Agreements with Executive Officers--Compensation Agreement with the Chief
Executive Officer." The levels of compensation provided under the 1993
Compensation Agreement and the 1998 Compensation Agreement were determined
when such agreements were entered into or amended based on a review by the
Committee and the Compensation Subcommittee and the Company's independent
compensation consultant of compensation levels of chief executive officers at
other companies in comparable industries and of certain chief executive
officers in other industries who, like Mr. Ralph J. Roberts, were founders of
companies and the persons primarily responsible for the growth of such
companies over a substantial period of time. The Committee and Compensation
Subcommittee also took into account its assessment of the importance of
maintaining the continued active participation of the Chief Executive Officer
in

                                      30


the Company's affairs over the periods covered by the 1993 Compensation
Agreement and the 1998 Compensation Agreement, the Company's growth and
overall performance during the ten years prior to 1993 and during the period
from 1993 to 1998, and the Chief Executive Officer's prior compensation levels
during those periods. The Committee and the Compensation Subcommittee did not
consider specific performance measures in approving the 1993 Compensation
Agreement and the 1998 Compensation Agreement, except to the extent that the
1993 Compensation Agreement provided for stock option grants in 1994 that were
inherently related to possible future appreciation in the Company's Common
Stock, and for bonuses and other compensation which replaced the Company's
discretionary bonus plan, which also related to appreciation in the value of
the Company's Common Stock over the period from 1986 through 1993.

  The Chief Executive Officer's compensation in 2000 consisted of the salary
and benefits fixed by the 1998 Compensation Agreement, an award of options to
purchase 250,000 shares of Class A Special Common Stock, and additional split-
dollar life insurance benefits in an amount fixed in 1994. The split-dollar
life insurance benefits were originally awarded pursuant to the Company's
undertaking in the 1993 Compensation Agreement to replace the potential
benefits provided prior to 1994 by a bonus plan that had been terminated, and
such benefits were generally calculated to produce the same after-tax cost to
the Company as the potential benefits to the Chief Executive Officer as of
March 15, 1994 under the terminated bonus plan. When such benefits were
awarded in 1994, the Company's compensation consultant reviewed the
calculation of the potential benefits provided by the terminated discretionary
bonus plan and of the expected after-tax cost of the additional split-dollar
life insurance benefits, and advised the Committee that its actions awarding
such benefits were appropriate and reasonable.

  The Compensation Subcommittee in 2000 also modified the terms of a variable
Death Benefit arrangement included in the 1998 Compensation Agreement. The
Death Benefit had replaced two bonus arrangements included in the 1993
Compensation Agreement that were based on appreciation of the Company's Class
A Common Stock from the date of grant to the date of exercise of the Chief
Executive Officer's options to purchase Class B Common Stock. The Compensation
Subcommittee determined that the after-tax present value cost to the Company
of the Death Benefit was $31.2 million, approximately equal to the cost of the
bonuses that would otherwise have been paid. Under the terms of the Death
Benefit, the Chief Executive Officer may request that the Company effectively
invest portions of the Death Benefit in investments identified by the Chief
Executive Officer. The formula under which the Death Benefit is calculated was
amended in 2000 to eliminate as of October 2000 an 8% interest-charge offset
on a $10.8 million portion of the Death Benefit, to the extent such portion
was so invested, which offset otherwise would have terminated at the earlier
of the Chief Executive's death or April 7, 2004. In making such modification,
the Compensation Subcommittee took account of the fact that, in light of the
Chief Executive Officer's continued health, the current actuarial value of the
Death Benefit, and thus its expected value as of 1998, is substantially lower
than was expected when the Death Benefit was created. The Compensation
Subcommittee believes that the change was consistent with the original purpose
of the Death Benefit to provide value equivalent to that of the two bonus
arrangements which it replaced. The Compensation Subcommittee also took into
account that the Chief Executive Officer continued to contribute significant
efforts on behalf of the Company in matters of extreme importance to the
Company and its shareholders.

  Compensation Related to Termination of Prior Cash Bonus Plan. Since 1994,
and continuing in 2000, certain compensation to the named executive officers
has related to the termination of a plan (approved by the Company's
shareholders in 1986) under which the Board of Directors awarded cash bonuses
to employees or directors exercising nonqualified options to reimburse such
persons for the income taxes payable by them upon exercise of the options and
receipt of the bonus. The Committee determined that this bonus plan did not
come within any of the exceptions to Section 162(m) of the Internal Revenue
Code, which became effective in 1994, and that if bonuses were to be awarded
under such plan in 1994 or thereafter, they might not be deductible. In
addition, in light of the appreciation in the Company's common stock over the
period from 1987 to 1993, the Board of Directors determined

                                      31


that continuation of the bonus plan could impose significant cash burdens on
the Company in future years. Accordingly, the Board of Directors terminated
the bonus plan as of December 31, 1993. However, the Committee and
Compensation Subcommittee recognized at such time that each of the named
executive officers had a reasonable expectation of substantial future
compensation under the bonus plan at the time it was terminated, and it
undertook to replace such compensation over a period of years in a manner
generally calculated to produce the same after-tax cost to the Company as the
potential benefits under the terminated bonus plan with respect to
appreciation in previously awarded nonqualified options prior to March 15,
1994. The Compensation Subcommittee has generally considered this compensation
to be payment of compensation which was essentially earned as of 1994, and
therefore has not taken it into account in assessing current compensation of
the named executive officers.

  As part of the Committee's effort to replace the potential benefits provided
by the Company's terminated bonus plan, the Committee has awarded annual lump-
sum bonuses, or, in the case of the Chief Executive Officer, as noted under
"Compensation of Chief Executive Officer," above, split-dollar life insurance
benefits, to each of the named executive officers. The Company's compensation
consultant advised the Committee that its actions to terminate the bonus plan
and award the substitute compensation described above were appropriate and
reasonable. The final such annual lump-sum bonuses were paid in 2000. The
Committee expects to continue to maintain the split-dollar life insurance
arrangements put in place for the Chief Executive Officer and Mr. Brodsky.

  Effect of Internal Revenue Code Section 162(m). Effective January 1, 1994,
Section 162(m) of the Internal Revenue Code provides that certain compensation
in excess of $1 million paid to the chief executive officer and the four most
highly compensated executive officers of a public company (determined as of
the last day of the company's tax year) will not be deductible for federal
income tax purposes.

  The Compensation Subcommittee engages in an ongoing review of the Company's
compensation practices for purposes of obtaining the maximum continued
deductibility of compensation paid by the Company consistent with its existing
commitments and ongoing competitive needs. Certain forms of compensation are
not included in determining whether the $1 million limit under Section 162(m)
has been exceeded, such as certain "performance-based" compensation adopted by
a committee of at least two outside directors and approved by shareholders,
compensation paid under binding written contracts (including nonqualified
stock options) in effect prior to the proposal of the new provision, and
compensation paid pursuant to certain plans approved by shareholders prior to
enactment of the new provision. These forms of compensation continue to be
deductible without regard to Section 162(m). In general, compensation pursuant
to nonqualified options granted to date under the Company's 1987 Stock Option
Plan and 1996 Stock Option Plan will continue to be deductible for federal
income tax purposes when the options are exercised, and bonuses awarded under
the Executive Cash Bonus Plan will be deductible when paid.

  The Compensation Subcommittee adopted the Executive Cash Bonus Plan to
conform to the requirements of Section 162(m) for deductibility of the bonus
payments awarded under such plan. See "Description of Executive Cash Bonus
Plan" under Proposal Four above.

  With respect to the 1993 and 1998 Compensation Agreements, a portion of the
compensation paid to the Chief Executive Officer will not or may not be
deductible under Section 162(m) to the extent it is paid during the course of
his employment as an executive officer of the Company. The amount of
compensation paid to the Chief Executive Officer in 2000 that is expected to
be nondeductible to the Company is approximately $1,069,000. In addition,
approximately $658,000 of the compensation paid in 2000 to Mr. Brian L.
Roberts, the Company's President, is also expected to be nondeductible under
Section 162(m), due principally to the payment of amounts to cover premiums on
term life insurance policies and bonuses related to income tax liabilities
arising therefrom, the payment of amounts with respect to income tax
obligations arising upon the exercise of certain stock options and other
incidental

                                      32


taxable fringe benefits, the fair market value of which was considered non-
performance-based compensation for tax purposes in 2000.

  The Compensation Subcommittee determined that the Company should provide the
above-described compensation regardless of its nondeductibility or potential
nondeductibility, based on, among other things, (1) its determination of a
fair and competitive compensation level for the officers involved taking into
account their contributions to the Company, which, in the case of the Chief
Executive Officer, extend over the entire course of the Company's history and
(2) the relatively minimal effect on the Company of forgoing deductibility of
the specific annual compensation in excess of $1 million.

                              COMCAST CORPORATION
                            AUDIT COMMITTEE CHARTER
                              Adopted May 1, 2000

I. Purpose

  The principal purpose of the Audit Committee (the "Committee") is to assist
the Board of Directors (the "Board") in fulfilling its responsibility to
oversee management's conduct of the Company's financial reporting process by,
among other things, reviewing significant financial reports and other
financial information provided by the Company to any governmental or
regulatory body, the public or others, the Company's systems of internal
accounting and financial controls, and the annual independent audit of the
Company's financial statements.

  In discharging its oversight role, the Committee is empowered to address any
matter brought to its attention with full access to all books, records,
facilities and personnel of the Company and the power to retain outside
counsel, outside auditors or other experts for this purpose.

  The Committee shall review the adequacy of this Charter on an annual basis.

II. Membership

  The Committee shall be comprised of no fewer than three members of the
Board, one of whom shall be appointed by the Board as the Committee's
chairperson. The Committee's composition shall meet the requirements of the
rules of the National Association of Securities Dealers, Inc., through its
Nasdaq Stock Market, Inc. ("Nasdaq") subsidiary. All of the members shall be
directors who, except as may otherwise be permitted under the Nasdaq rules,
have no relationship to the Company that may interfere with the exercise of
their independence from management and the Company. Each member of the
Committee shall be financially literate or become financially literate within
a reasonable period of time after appointment to the Committee, and at least
one member of the Committee shall have accounting or related financial
management expertise, as the foregoing qualifications are interpreted by the
Board in its business judgment.

III. Key Responsibilities

  The Committee is to serve in an oversight capacity and is not intended to be
part of the Company's operational or managerial decision-making process. The
Company's management is responsible for preparing the Company's financial
statements and the outside auditors are responsible for auditing the financial
statements. Additionally, the Committee recognizes that the Company's
financial management, including the internal audit staff, as well as the
Company's outside auditors, have more time, knowledge and detailed information
concerning the Company than do Committee members; consequently, in carrying
out its oversight responsibilities, the Committee is not providing any expert
or special assurance as to the Company's financial statements or any
certification as to the outside auditors' work.

  Consistent with the above, the Committee shall:

    Provide an open avenue of communication among management, the internal
  audit staff, the outside auditors and the Board.

    Review with management and the outside auditors the audited financial
  statements to be included in the Company's Annual Report on Form 10-K (or
  the Annual Report to Shareholders, if distributed prior to the filing of
  the Form 10-K) prior to their filing with the Securities and Exchange
  Commission (or prior to such distribution, if earlier) and, in connection
  therewith,

                                      A-1


  review and consider with the outside auditors the matters required to be
  discussed by Statement of Auditing Standards ("SAS") No. 61, as it may be
  modified or supplemented.

    Either on its own or through its chairperson, review with the outside
  auditors, prior to the Company's filing of each quarterly report on Form
  10-Q with the Securities and Exchange Commission, the Company's interim
  financial statements to be included in such Form 10-Q and the matters
  required to be discussed by SAS No. 71, as it may be modified or
  supplemented.

    Discuss with management, the internal audit staff, and the outside
  auditors the quality and adequacy of the Company's internal accounting and
  financial controls.

    Receive from the outside auditors annually a formal written statement
  delineating all relationships between the outside auditors and the Company
  consistent with Independence Standards Board Standard No. 1.

    Discuss with the outside auditors any disclosed relationships or services
  contained in the formal written statement received from the outside
  auditors that may impact the objectivity and independence of the outside
  auditors.

    Take, or recommend that the Board take, appropriate action to oversee the
  independence of the outside auditors.

  The outside auditors are ultimately accountable to the Board and the
Committee, as representatives of the Company's shareholders, and these
shareholder representatives have the ultimate authority and responsibility to
select, evaluate, and, where appropriate, replace the outside auditors (or to
nominate the outside auditors to be proposed for shareholder approval in any
proxy statement).

written notice (or notice in another form pursuant to procedures established by
the Committee) of such change to the Committee on or before the 15th day of the
month immediately preceding the Offering Commencement Date for the Offering for
which such change is effective.

6.   Purchase of Shares.

     (a) In General. On each Offering Termination Date, each Participant shall
be deemed to have purchased a number of whole Shares equal to the quotient
obtained by dividing the balance credited to the Participant's Account as of the
Offering Termination Date, by the Purchase Price, rounded to the next lowest
whole Share. Shares deemed purchased by a Participant under the Plan shall be
credited to the Participant's Brokerage Account as soon as practicable following
the Offering Termination Date.

     (b) Terminating Events. The Company shall give Participants at least 30
days' notice (or, if not practicable, such shorter notice as may be reasonably
practicable) prior to the anticipated date of the consummation of a Terminating
Event. The 20th day following the issuance of such notice by the Company (or
such earlier date as the Board or the Committee may reasonably determine) shall
constitute the Offering Termination Date for any outstanding Offering.

     (c) Fractional Shares and Minimum Number of Shares. Fractional Shares shall
not be issued under the Plan. Amounts credited to an Account remaining after the
application of such Account to the purchase of Shares under the Plan shall be
credited to the Participant's Account for the next succeeding Offering, or, at
the Participant's election, returned to the Participant as soon as practicable
following the Offering Termination Date, without interest.

     (d) Transferability of Rights to Purchase Shares. No right to purchase
Shares pursuant to the Plan shall be transferable other than by will or by the
laws of descent and distribution, and no such right to purchase Shares pursuant
to the Plan shall be exercisable during the Participant's lifetime other than by
the Participant.

7.   Withdrawals.

     (a) Withdrawal of Account. A Participant may elect to withdraw the balance
credited to the Participant's Account by providing a Termination Form to the
Committee at any time before the Offering Termination Date applicable to any
Offering.


     (b) Notification of Withdrawal. A Participant may withdraw all, but not
less than all, of the amounts credited to the Participant's Account by
delivering a Termination Form to the Committee at least 10 days preceding the
Offering Termination Date. All amounts credited to such Participant's Account
shall be paid as soon as practicable following the Committee's receipt of the
Participant's Termination Form, and no further Payroll Deductions will be made
with respect to the Participant. A Participant who elects to withdraw from an
Offering pursuant to Paragraph 7(a) of the Plan shall not be eligible to
participate in the Offering next following the date on which the Participant
delivers a Termination Form to the Committee.

     (c) Termination of Employment. Upon termination of a Participant's
employment for any reason other than death, including termination due to
disability or continuation of an approved leave of absence beyond the Offering
Period which commenced prior to beginning of an approved leave of absence, all
amounts credited to such Participant's Account shall be returned to the
Participant. In the event of a Participant's (1) termination of employment due

Participant's Account shall be returned to the Participant's Successor-in-

or other securities of the Company, whether through merger, consolidation,
reorganization, recapitalization, stock dividend, stock split-up or other
substitution of securities of the Company, the Board or the Committee shall make
appropriate equitable anti-dilution adjustments to the number and class of
shares of stock available for issuance under the Plan, to the number and class
of shares of stock subject to outstanding Offerings and to the Purchase Price.
Any reference to the Purchase Price in the Plan and in any related documents
shall be a reference to the Purchase Price as so adjusted. Any reference to the
term "Shares" in the Plan and in any related documents shall be a reference to
the appropriate number and class of shares of stock available for issuance under
the Plan, as adjusted pursuant to this Paragraph 9. The Board's or the
Committee's adjustment shall be effective and binding for all purposes of this
Plan. All Shares issued pursuant to the Plan shall be validly issued, fully paid

conditioned upon such approval, and no Share certificates shall be issued until
such approval. If shareholder approval is not received within 12 months before

                              COMCAST CORPORATION

                         1996 EXECUTIVE CASH BONUS PLAN
                     (as amended through March 21, 2001)

          1. PURPOSE

          The purpose of the Plan is to provide, subject to shareholder approval
and approval by the Committee (as defined below), performance-based cash bonus
compensation for certain employees of Comcast Corporation, a Pennsylvania
corporation (the "Company") in accordance with a formula that is based on the
financial success of the Company as part of an integrated compensation program
which is intended to assist the Company in motivating and retaining employees of
superior ability, industry and loyalty.

          2. DEFINITIONS

          The following words and phrases as used herein shall have the
following meanings, unless a different meaning is plainly required by the
context:

          "Board of Directors" shall mean the Board of Directors of the Company.

          "Cash Flow" shall mean the operating income before depreciation and
amortization for the Company and those of its affiliates which are included with
the Company in its consolidated financial statements as prepared by the Company
in accordance with generally accepted accounting principles.

          "Committee" shall mean the Subcommittee on Performance-Based
Compensation of the Compensation Committee of the Board of Directors.

          "Company" shall mean Comcast Corporation, a Pennsylvania corporation,
and any successor thereto.

          "First Tier Goal" shall mean the performance goal, measured in terms
of level of Cash Flow, as established by the Committee for each Plan Year. The
First Tier Goal is the performance measure which, if achieved, permits payment
to each Participant of 66% of the Participant's Target Bonus. The Committee
shall in all events establish the First Tier Goal for each Plan Year no later
than 90 days after the first day of the Plan Year or, if sooner, within the
first 25% of the Plan Year. The First Tier Goal shall be established at the
discretion of the Committee, provided, however, that the Committee must
determine that, as of the date the First Tier Goal is established, it is
substantially uncertain whether the level of Cash Flow required to meet the
First Tier Goal will be achieved.



          "Participant" shall mean those persons eligible to participate in the
Plan in accordance with Section 3.

          "Plan" shall mean the Comcast Corporation 1996 Executive Cash Bonus
Plan.

          "Plan Year" shall mean the calendar year, except that the first Plan
Year shall be the period from July 1, 1996 through December 31, 1996.

          "Second Tier Goal" shall mean the performance goal, measured in terms
of level of Cash Flow, as established by the Committee for each Plan Year. The
Second Tier Goal is the performance measure which, if achieved, permits payment
to each Participant of 100% of the Participant's Target Bonus. The Committee
shall establish the Second Tier Goal for each Plan Year at the same time that it
establishes the First Tier Goal for such Plan Year. The Second Tier Goal shall
be a level of Cash Flow chosen at the discretion of the Committee that is higher
than the level of Cash Flow chosen for the Plan Year as the First Tier Goal.

          "Target Bonus" shall mean, with respect to any Participant for any
Plan Year, the sum of (a) the Target Percentage of the Participant's base salary
and any guaranteed bonus (other than any bonus awarded on account of the
termination as of December 31, 1993, of the Company's discretionary cash bonus
plan) as of the first day of the Plan Year and (b) the amount, if any, of such
Participant's Target Bonus for any prior Plan Year which was not earned due to
failure to meet the First Tier Goal or the Second Tier Goal; provided, however,
that in no event shall any Participant's Target Bonus for any Plan Year exceed
$3,000,000.

          "Target Percentage" shall mean, with respect to any Participant for
any Plan Year, a percentage, not to exceed 150%, established by the Committee
with respect to such Participant and such Plan Year. If no other percentage is
selected by the Committee, the Target Percentage shall be 50%.

          3. PARTICIPATION

          The Participants in the Plan shall be

          (a) Brian L. Roberts, Lawrence S. Smith, John R. Alchin and Stanley
Wang;

          (b) Effective for Plan Years beginning after 1999, Brian L. Roberts,
Lawrence S. Smith, John R. Alchin, Stanley Wang, Stephen B. Burke, Michael A.
Tallent, Bradley P. Dusto and David N. Watson;

          (c) Effective for Plan Years beginning after 2000, Brian L. Roberts,
Lawrence S. Smith, John R. Alchin, Stanley Wang,  Stephen B. Burke, Michael A.
Tallent, Bradley P. Dusto, David N. Watson, Arthur R. Block, Mark A. Coblitz and
Robert A. Pick; and



          (d) Effective for Plan Years beginning after 2003, Brian L. Roberts,
Lawrence S. Smith, John R. Alchin, Stanley Wang,  Stephen B. Burke, Michael A.
Tallent, Bradley P. Dusto, David N. Watson, Arthur R. Block, Mark A. Coblitz,
Robert A. Pick and Lawrence J. Salva.

In addition, Participants in the Plan shall include such other key executives as
may be designated by the Committee to participate in the Plan from time to time.

          4. TERM OF PLAN

          The original effective date of the Plan was July 1, 1996. Subject to
approval of the shareholders of the Company, the Plan shall continue until all
amounts required to be paid with respect to all Plan Years up through and
including the Plan Year ending December 31, 2006 are paid by the Company, unless
the Plan is sooner terminated by the Board of Directors.

          5. BONUS ENTITLEMENT

          Each Participant shall be entitled to receive a bonus in accordance
with the provisions of Section 6 of the Plan only after certification by the
Committee that the performance goals set forth in Section 6 have been satisfied.
The bonus payment under the Plan shall be paid to each Participant as soon as
practicable following the close of the Plan Year with respect to which the bonus
is to be paid. Notwithstanding anything contained herein to the contrary, no
bonus shall be payable under the Plan without the prior disclosure of the terms
of the Plan to the shareholders of the Company and the approval of the Plan by
such shareholders.

          6. AMOUNT OF PERFORMANCE-BASED COMPENSATION BONUS

          (a) Each Participant in the Plan shall be entitled to a bonus with
respect to a Plan Year which is equal to 66% of the Participant's Target Bonus
if the Company's Cash Flow for the Plan Year is at least equal to the First Tier
Goal, and 100% of the Target Bonus if the Company's Cash Flow for the Plan Year
is at least equal to the Second Tier Goal. If the level of Cash Flow for the
Plan Year is higher than the First Tier Goal and lower than the Second Tier
Goal, the bonus with respect to such Plan Year shall be such percentage of the
Participant's Target Bonus in excess of 66% as is determined by prorating the
difference between 100% and 66% according to the level of Cash Flow in excess
of the First Tier Goal divided by the difference between the levels of Cash Flow
represented by the Second Tier Goal and the First Tier Goal. If the level of
Cash Flow for a Plan Year is below the First Tier Goal established with respect
to such Plan Year, no bonus shall be payable under the Plan for that Plan Year.

          (b) In the event any payment of a bonus otherwise payable under the
Plan occurs more than two months after the close of the Plan Year with respect
to which the bonus is paid because the required disclosure of the terms of the
Plan to the shareholders of the Company and the approval of the Plan by such
shareholders delays such bonus payment, the amount of the



bonus otherwise payable shall be increased by the amount such bonus payment
would earn if it were invested in an investment bearing a 7% annual rate of
return, compounded daily, or such other reasonable rate of interest as may be
determined by the Committee, during the period from the close of the Plan Year
with respect to which such bonus is paid and the date the bonus is actually
paid.

          (c) Notwithstanding anything contained herein to the contrary, in the
event there is a significant acquisition or disposition of any assets, business
division, company or other business operations of the Company that is reasonably
expected to have an effect on Cash Flow as otherwise determined under the terms
of the Plan, the First Tier Goal and the Second Tier Goal shall be adjusted to
take into account the impact of such acquisition or disposition by increasing or
decreasing such goals in the same proportion as Cash Flow of the Company would
have been affected for the prior Plan Year on a pro forma basis had such an
acquisition or disposition occurred on the same date during the prior Plan Year
(except in the case of the first Plan Year the adjustment shall be made by
reference to the effect such an acquisition or disposition on the same date
during the prior calendar year would have had on Cash Flow for the period
commencing July 1, 1995 and ending December 31, 1995). Such adjustment shall be
based upon the historical equivalent of Cash Flow of the assets so acquired or
disposed of for the prior Plan Year, as shown by such records as are available
to the Company, as further adjusted to reflect any aspects of the transaction
that should be taken into account to ensure comparability between amounts in the
prior Plan Year and the current Plan Year.

          (d) Notwithstanding the determination of the amount of a Participant's
bonus payable with respect to any Plan Year under Section 6(a), the Committee
shall have the discretion to reduce or eliminate the bonus otherwise payable to
a Participant if it determines that such a reduction or elimination of the bonus
is in the best interests of the Company.

          7. COMMITTEE

          (a) Powers. The Committee shall have the power and duty to do all
things necessary or convenient to effect the intent and purposes of the Plan and
not inconsistent with any of the provisions hereof, whether or not such powers
and duties are specifically set forth herein, and, by way of amplification and
not limitation of the foregoing, the Committee shall have the power to:

              (i) provide rules and regulations for the management, operation
and administration of the Plan, and, from time to time, to amend or supplement
such rules and regulations;

              (ii) construe the Plan, which construction, as long as made in
good faith, shall be final and conclusive upon all parties hereto; and

              (iii) correct any defect, supply any omission, or reconcile any
inconsistency in the Plan in such manner and to such extent as it shall deem
expedient to carry


the same into effect, and it shall be the sole and final judge of when such
action shall be appropriate.

          The resolution of any questions with respect to payments and
entitlements pursuant to the provisions of the Plan shall be determined by the
Committee, and all such determinations shall be final and conclusive.

              (b) Indemnity. No member of the Committee shall be directly or
indirectly responsible or under any liability by reason of any action or default
by him as a member of the Committee, or the exercise of or failure to exercise
any power or discretion as such member. No member of the Committee shall be
liable in any way for the acts or defaults of any other member of the Committee,
or any of its advisors, agents or representatives. The Company shall indemnify
and save harmless each member of the Committee against any and all expenses and
liabilities arising out of his own membership on the Committee.

              (c) Compensation and Expenses. Members of the Committee shall
receive no separate compensation for services other than compensation for their
services as members of the Board of Directors, which compensation can include
compensation for services at any committee meeting attended in their capacity as
members of the Board of Directors. Members of the Committee shall be entitled to
receive their reasonable expenses incurred in administering the Plan. Any such
expenses, as well as extraordinary expenses authorized by the Company, shall be
paid by the Company.

              (d) Participant Information. The Company shall furnish to the
Committee in writing all information the Company deems appropriate for the
Committee to exercise its powers and duties in administration of the Plan. Such
information shall be conclusive for all purposes of the Plan and the Committee
shall be entitled to rely thereon without any investigation thereof; provided,
however, that the Committee may correct any errors discovered in any such
information.

              (e) Inspection of Documents. The Committee shall make available to
each Participant, for examination at the principal office of the Company (or at
such other location as may be determined by the Committee), a copy of the Plan
and such of its records, or copies thereof, as may pertain to any benefits of
such Participant under the Plan.

          8. TERMINATION AND AMENDMENT

          The Plan may be terminated or revoked by the Company at any time and
amended by the Company from time to time, provided that neither the termination,
revocation or amendment of the Plan may, without the written approval of the
Participant, reduce the amount of a bonus payment that is due, but has not yet
been paid, and provided further that no changes that would increase the amount
of bonuses determined under provisions of the Plan shall be effective without
approval by the Committee and without disclosure to and approval by the
shareholders of the Company in a separate vote prior to payment of such bonuses.
In addition,


the Plan may be modified or amended by the Committee, as it deems appropriate,
in order to comply with any rules, regulations or other guidance promulgated by
the Internal Revenue Service with respect to applicable provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), as they relate to the
exemption for "performance-based compensation" under the limitations on the
deductibility of compensation imposed under Code Section 162(m).

          9.  MISCELLANEOUS PROVISIONS

              (a) Unsecured Creditor Status. A Participant entitled to a bonus
payment hereunder, shall rely solely upon the unsecured promise of the Company,
as set forth herein, for the payment thereof, and nothing herein contained shall
be construed to give to or vest in a Participant or any other person now or at
any time in the future, any right, title, interest, or claim in or to any
specific asset, fund, reserve, account, insurance or annuity policy or contract,
or other property of any kind whatever owned by the Company, or in which the
Company may have any right, title, or interest, nor or at any time in the
future.

              (b) Other Company Plans. It is agreed and understood that any
benefits under this Plan are in addition to any and all benefits to which a
Participant may otherwise be entitled under any other contract, arrangement, or
voluntary pension, profit sharing or other compensation plan of the Company,
whether funded or unfunded, and that this Plan shall not affect or impair the
rights or obligations of the Company or a Participant under any other such
contract, arrangement, or voluntary pension, profit sharing or other
compensation plan.

              (c) Separability. If any term or condition of the Plan shall be
invalid or unenforceable to any extent or in any application, then the remainder
of the Plan, with the exception of such invalid or unenforceable provision,
shall not be affected thereby, and shall continue in effect and application to
its fullest extent.

              (d) Continued Employment. Neither the establishment of the Plan,
any provisions of the Plan, nor any action of the Committee shall be held or
construed to confer upon any Participant the right to a continuation of
employment by the Company. The Company reserves the right to dismiss any
employee (including a Participant), or otherwise deal with any employee
(including a Participant) to the same extent as though the Plan had not been
adopted.

              (e) Incapacity. If the Committee determines that a Participant is
unable to care for his affairs because of illness or accident, any benefit due
such Participant under the Plan may be paid to his spouse, child, parent, or any
other person deemed by the Committee to have incurred expense for such
Participant (including a duly appointed guardian, committee, or other legal
representative), and any such payment shall be a complete discharge of the
Company's obligation hereunder.

              (g) Jurisdiction. The Plan shall be construed, administered, and
enforced according to the laws of the Commonwealth of Pennsylvania, except to
the extent that


such laws are preempted by the Federal laws of the United States of America.

              (h) Withholding. The Participant shall make appropriate
arrangements with the Company for satisfaction of any federal, state or local
income tax withholding requirements and Social Security or other tax
requirements applicable to the accrual or payment of benefits under the Plan. If
no other arrangements are made, the Company may provide, at its discretion, for
any withholding and tax payments as may be required.
