                                 PROXY STATEMENT

                        ANNUAL MEETING OF STOCKHOLDERS OF

                         AUTOMATIC DATA PROCESSING, INC.
                    One ADP Boulevard o Roseland, New Jersey 07068

                         TO BE HELD ON NOVEMBER 13, 2001

                       SOLICITATION AND REVOCATION OF PROXY

     The accompanying proxy is being solicited by the Board of Directors of the
Company for use at the forthcoming Annual Meeting of Stockholders. Each
stockholder giving such a proxy has the power to revoke the same at any time
before it is voted by so notifying the Secretary of the Company in writing. All
expenses in connection with the solicitation will be borne by the Company. This
Proxy Statement and the accompanying proxy are being mailed to stockholders on
or about September 24, 2001.

     The Company has one class of securities outstanding and entitled to vote at
the Annual Meeting of Stockholders, its Common Stock, par value $.10 per share.
At the close of business on September 14, 2001, the record date for determining
stockholders entitled to notice of and to vote at the meeting, the Company had
issued and outstanding 624,070,462 shares of Common Stock (excluding 14,630,123
treasury shares not entitled to vote). Each outstanding share of Common Stock is
entitled to one vote with respect to each matter to be voted on at the meeting.

     The representation in person or by proxy of a majority of the shares
entitled to vote shall constitute a quorum at the Annual Meeting of
Stockholders. Directors are elected by a plurality of the affirmative votes
cast. The affirmative vote of the holders of a majority of the outstanding
shares present in person or by proxy and entitled to vote thereon is required to
(i) approve the amendment to the Company's 2000 Key Employees' Stock Option Plan
to increase by 22,000,000 the number of shares of Common Stock of the Company
available for option grants to employees, (ii) approve the Company's 2001
Executive Incentive Compensation Plan, and (iii) ratify the appointment of
Deloitte & Touche LLP as the Company's independent certified public accountants.
Under the Company's Amended and Restated Certificate of Incorporation and
By-Laws and under Delaware law, abstentions and "non-votes" are counted as
present in determining whether the quorum requirement is satisfied. With regard
to the election of directors, votes may be cast in favor or withheld. Votes that
are withheld will be excluded entirely from the vote and will have no effect.
Abstentions may be specified on any proposal (other than the election of
directors) and will have the effect of a negative vote. Under applicable
Delaware law, a non-vote will have no effect on the outcome of any of the
matters referred to in this Proxy Statement. A non-vote occurs when a nominee
holding shares for a beneficial owner votes on one proposal, but does not vote
on another proposal because the nominee does not have discretionary voting power
and has not received instructions from the beneficial owner.

     The Company's Board of Directors has adopted a policy whereby stockholders'
proxies are received by the Company's independent tabulators and the vote is
certified by independent inspectors of election. Proxies and ballots that
identify the vote of individual stockholders will be kept confidential from the
Company's management and directors, except as necessary to meet legal
requirements, in cases where stockholders request disclosure, or in a contested
election.






                                   PROPOSAL 1

                              ELECTION OF DIRECTORS

     Properly executed proxies will be voted as marked, and if not marked, will
be voted in favor of the election of the persons named below (each of whom is
now a director) as directors to serve until the next Annual Meeting of
Stockholders and until their successors are duly elected and qualified. If any
nominee does not remain a candidate at the time of the meeting (a situation
which management does not anticipate), proxies solicited hereunder will be voted
in favor of those nominees who do remain as candidates and may be voted for
substitute nominees designated by the Board of Directors.

or other fee arrangements provided by the Company.

     The non-employee directors of the Company are entitled to participate in
the 1989 Non-Employee Director Stock Option Plan (the "Directors' Plan")
pursuant to which options to purchase 12,500 shares of Common Stock will
automatically be granted to persons who become non-employee directors. In
addition, each non-employee director will be granted an additional option to
purchase 12,500 shares on the first business day after each fifth anniversary of
the date of the initial grant to each such non-employee director, provided that
he or she is then still serving in such capacity. The Directors' Plan was
adopted on November 2, 1989 and will remain in effect until terminated by action
of the Board of Directors. All options have been and will be granted at the fair
market value of the Common Stock, determined on the basis of the closing price
of the Common Stock in consolidated trading on the date of grant, as reported in
The Wall Street Journal. Twenty percent of the options granted under the
Directors' Plan become exercisable on the first anniversary of the date such
options are granted, and twenty percent become exercisable on each successive
anniversary date thereafter until all such options are exercisable, provided
that options become exercisable only if the director is then still serving in
such capacity, unless certain specified events occur such as the death,
disability or retirement of a director, in which case the options shall
immediately vest and become fully exercisable. All options granted under the
Directors' Plan have a term of ten years. No options to purchase shares of
Common Stock were granted under the Directors' Plan in fiscal 2001.

     Any person who first becomes a non-employee director after August 13, 1997
is not eligible to receive a pension from the Company. A non-employee director
(who was a director on August 13, 1997) who

                                       4



retires after 20 years of service in such capacity and having attained the age
of 70 will receive a pension of $25,000 per year for the remainder of his or her
life. If such non-employee director retires after having attained the age of 65
with 15 years of service, he or she will receive a pension of $12,500 per year.

(1)   None of the named executive officers received any perquisites or other
      personal benefits of an amount, or any other annual compensation of a
      type, required to be reported by the Securities and Exchange Commission
      pursuant to applicable rules and regulations.

      As of June 30, 2001, the aggregate number of shares of restricted stock
      held by a named executive officer and the aggregate fair market value of

      by such named executive officer by the difference between $49.70, the
      closing price of the Common Stock on June 30, 2001, and $.10, the
      consideration paid per share of restricted stock) was: Mr. Weinbach,
      48,800 shares ($2,420,480); Mr. Butler, 61,800 shares ($3,065,280); Mr.

Stock Option Plans

     The Company has in effect a 1990 Key Employees' Stock Option Plan (the
"1990 Plan") and a 2000 Key Employees' Stock Option Plan (the "2000 Plan"). The
1990 Plan and the 2000 Plan collectively are referred to as the "Option Plans".
Officers and key employees are eligible to participate in the Option Plans,
which permit the issuance, in addition to non-qualified options, of "incentive
stock options" ("ISOs") within the meaning of section 422 of the Internal
Revenue Code of 1986, as amended (the "Code"). The Company has ceased granting
options under the 1990 Plan, but outstanding options under the 1990 Plan remain
valid. In the event of a termination of their employment following a change in
control of the Company, the unvested portion of the stock options of Messrs.
Weinbach and Butler will be subject to accelerated vesting as further described
in this Proxy Statement under the heading "Employment Agreements". In the event
of a termination of their employment following a change in control of the
Company, the unvested portion of the stock options of Messrs. Fradin, Hall,
Hogan and Daly will be subject to accelerated vesting as further described in
this Proxy Statement under the heading "Change in Control Severance Plan for
Corporate Officers".

     The Option Plans are administered by the Compensation Committee of the
Board of Directors. The Compensation Committee has the authority to determine
the employees to whom options will be granted and, subject to the Option Plans,
the terms and amount of options granted.

     ISOs and non-qualified options expire no more than ten years from their
date of grant, with an exercise price no less than 100% of the fair market value
on the date of grant. The Board of Directors has resolved that once granted, no
ISO or non-qualified option may be repriced.

     An optionee has no rights as a stockholder with respect to any shares
covered by his or her options until the date of issuance of a stock certificate
to him or her for such shares. During the life of the optionee, the option is
exercisable only by him or her. No option is exercisable more than 60 days after
termination of employment, or (if termination is due to the death of an
optionee) more than six months after the appointment and qualification of an
executor or administrator of the deceased optionee's estate or 12 months after
the death of the optionee, whichever occurs earlier.

     The following table sets forth certain information concerning stock option
grants to the named executive officers during the fiscal year ended June 30,
2001.

-----------------------
(1)   410,000 options were granted pursuant to the 2000 Plan. The options were
      granted at an exercise price equal to the fair market value of the
      Company's Common Stock on the date of grant. The options were granted for
      terms of ten years, and vest during periods up to six years subsequent to
      the date of grant.

                                       9


(2)   The grant date values were calculated on the basis of the Black-Scholes
      option pricing model. Options were assumed to be exercised 6.3 years after
      the date of grant, based on historical experience. A risk-free interest
      rate of 6.00%, stock price volatility of 27.88% and a dividend yield of
      0.81% was used in the calculation of the option grants to Messrs. Weinbach
      and Butler. A risk-free interest rate of 5.79%, stock price volatility of
      28.23% and a dividend yield of 0.77% was used in the calculation for the
      option grants to Messrs. Fradin, Hall, Hogan and Daly. A discount factor
      of 3% was applied to the calculated value to reflect the risk of
      forfeiture during the option term. The actual value of the options will
      depend on the market value of the Company's Common Stock on the dates the
      options are exercised. No realization of value from the options is
      possible without an increase in the price of the Company's Common Stock,
      which would benefit all stockholders commensurately.

     Compensation covered by the Pension Plan is limited to January 1 base
salary up to the current compensation limit in effect for the plan year.
Compensation covered under the Supplemental Retirement Plan includes cash
compensation (paid or deferred) and compensation from restricted stock vesting
during the year. Benefits under the Supplemental Retirement Plan are subject to
reduction for social security, Pension Plan and 401(k) benefits.

     Messrs. Weinbach, Butler, Fradin, Hall, Hogan and Daly have 20, 25, 3, 1, 7
and 11 years of credited service, respectively, under the Pension Plan and 12,
12, 4, 2, 6 and 7 years of credited service, respectively, under the
Supplemental Retirement Plan. In addition, unless his employment is terminated
for cause, Mr. Weinbach will receive the maximum benefits available under the
Supplemental Retirement Plan, and his benefit will not be reduced for
commencement prior to age 65 as long as the Compensation Committee deems his
retirement prior to age 65 is in the Company's best interest. The figures shown
on the table above are for a straight-life annuity commencing at age 65. Reduced
benefits are available at earlier ages and in other forms of benefits.

Change in Control Severance Plan for Corporate Officers

     To aid the Company in retaining its officers, the Board approved the
Automatic Data Processing, Inc. Change in Control Severance Plan for Corporate
Officers (the "CIC Plan"), which provides for the payment of specified benefits
to officers selected by the Board if their employment terminates after a "change
in control" (as defined below) of the Company. All corporate officers of the
Company ("Participants") participate in the CIC Plan. As of August 31, 2001,
there were 28 Participants in the CIC Plan.

     The CIC Plan provides that Participants who are terminated by the Company
without "cause" (as defined in the CIC Plan) or by the Participant for "good
reason" (as defined in the CIC Plan) (a "Qualifying Termination") during the
two-year period following the occurrence of a change in control will receive a
payment equal to 150% of such Participant's "current total annual compensation."
Participants who have a Qualifying Termination during the third year following
the occurrence of a change in control will receive a payment equal to 100% of
such Participant's current total annual compensation. A Participant's "current
total annual compensation" equals his or her highest rate of annual salary
during the calendar year in which his or her employment terminates or the year
immediately prior to the year of such termination plus his or her average annual
bonus compensation earned in respect of the two most recent calendar years
immediately preceding the calendar year in which his or her employment
terminates.

     In addition to the payments described in the preceding paragraph, options
to purchase Company stock held by Participants who have a Qualifying Termination
during the two-year period following the occurrence of a change in control will
become fully vested and exercisable. Options to purchase Company

                                       11



stock held by Participants who have a Qualifying Termination during the third
year following the occurrence of a change in control will become fully vested
and exercisable to the extent that such options would have otherwise vested
Within one year after the Qualifying Termination.

     Likewise, restricted shares of Company stock ("Restricted Shares") held by
Participants who have a Qualifying Termination during the two-year period
following the occurrence of a change in control will become fully vested as to
those Restricted Shares for which vesting restrictions would otherwise have
lapsed within two years after the Qualifying Termination. Restricted Shares held
by Participants who have a Qualifying Termination during the third year
following the occurrence of a change in control will become fully vested to the
extent that vesting restrictions would have lapsed within one year after the
Qualifying Termination.

     Generally, the CIC Plan supersedes any other change in control severance
plans, policies and practices of the Company with respect to the Participants.
Messrs. Weinbach and Butler are entitled to receive the greater of the benefits
and payments and more favorable conditions provided under their employment
agreements and the CIC Plan on an item-by-item basis.

     A "change in control" as defined in the CIC Plan will have occurred if (i)
any "Person" (as defined in Section 3(a)(9) of the Securities Exchange Act of
1934, as amended (the "Exchange Act")), excluding the Company, any subsidiary of
the Company, or any employee benefit plan sponsored or maintained by the Company
(including any trustee of any such plan acting in its capacity as trustee),
becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act)
of securities of the Company representing 35% or more of the total combined
voting power of the Company's then outstanding securities; (ii) there occurs a
merger, consolidation or other business combination of the Company (a
"Transaction"), other than a Transaction immediately following which the
stockholders of the Company immediately prior to the Transaction continue to be
the beneficial owners of securities of the resulting entity representing more
than 65% of the voting power in the resulting entity, in substantially the same
proportions as their ownership of Company voting securities immediately prior to
the Transaction; or (iii) there occurs the sale of all or substantially all of
the Company's assets, other than a sale immediately following which the
stockholders of the Company immediately prior to the sale are the beneficial
owners of securities of the purchasing entity representing more than 65% of the
voting power in the purchasing entity, in substantially the same proportions as
their ownership of Company voting securities immediately prior to the
Transaction. If instructed by a Participant, the Company will reduce payments
under the CIC Plan to avoid the application of excise taxes pursuant to section
4999 of the Code.


Employment Agreements

     Arthur F. Weinbach has entered into an employment agreement with the
Company as of August 13, 2001. The agreement provides for successive one-year
terms unless terminated by the Company or Mr. Weinbach at least six months prior
to the end of the applicable one-year term. Mr. Weinbach's annual base salary is
to be no less than $750,000, and his annual target bonus is to be no less than
$485,000. The actual bonus paid to Mr. Weinbach is based upon his accomplishment
of pre-established performance goals that include business growth and increased
profitability. The agreement provides that Mr. Weinbach is to be granted
performance-based restricted stock awards for a number of shares so that
restrictions may lapse in each fiscal year of the Company on shares with a
market value on the date of the award of at least $1,000,000. The agreement also
provides that Mr. Weinbach will at all times own sufficient shares of restricted
stock such that restrictions may lapse during each of the following two fiscal
years on a number of shares having a market value on the date of their award of
at least $1,000,000. The agreement further provides that Mr. Weinbach is to be
granted, on an annual basis, a minimum of 170,000 options to purchase shares of
Common Stock and that all options to purchase Common Stock not yet vested at the
time of Mr. Weinbach's retirement would fully vest upon his retirement. If the
Company terminates Mr. Weinbach's employment without cause, then he is entitled
to receive his base salary for 18 months and continue to vest in his restricted
stock awards and stock options. If Mr. Weinbach's employment is terminated
following a "change in control" (as defined below) of the Company, he will
receive a termination payment equal to a percentage, ranging from 300% if such
termination occurs within two

                                       12



years after such change in control to 100% if it occurs after the third year, of
his annual base salary and his "current total annual compensation" (as defined
below). In addition, all of his stock options will become fully vested and all
of his restricted stock having restrictions lapsing within three years after
such termination shall have such restrictions automatically removed.

     The definition of a "change in control" in Mr. Weinbach's employment
agreement is the same as the definition of a "change in control" under the CIC
Plan except for the percentage in clause (i) of such CIC Plan definition which
is 25% under Mr. Weinbach's employment agreement.

     Mr. Weinbach's "current total annual compensation" equals his highest rate
of annual salary during the calendar year in which his employment terminates or
the year immediately prior to the year of such termination plus his average
annual bonus compensation earned in respect of the two most recent calendar
years immediately preceding the calendar year in which his employment
terminates. Mr. Weinbach's employment agreement provides that in the event any
payment from the Company to him results in the imposition of an excise tax under
section 4999 of the Code, he will receive an additional payment such that after
the payment of all such excise taxes and any taxes on the additional payments he
will be in the same after-tax position as if no excise tax had been imposed.

     Mr. Butler has entered into an agreement with the Company that provides
that if his employment is terminated following a "change in control" (as defined
below) of the Company, he will receive a termination payment equal to a
percentage, ranging from 200% if such termination occurs within two years of
such change in control to 100% if it occurs after the third year, of his annual
base salary and his average annual bonus for the prior two years. In addition,
all of his stock options will become fully vested and all of his restricted
stock having restrictions lapsing within three years after such termination
shall have such restrictions automatically removed.

     The definition of a "change in control" in Mr. Butler's employment
agreement, as modified by the CIC Plan, is the same as the definition of a
"change in control" under Mr. Weinbach's employment agreement noted above.

     Mr. Butler's employment agreement provides that in the event any payment
from the Company to him results in the imposition of an excise tax under section
4999 of the Code, he will receive an additional payment such that after the
payment of all such excise taxes and any taxes on the additional payments he
will be in the same after-tax position as if no excise tax had been imposed.

Certain Transactions

     Harvey M. Krueger, a director of the Company, is Vice Chairman of Lehman
Brothers, which provided various investment banking and brokerage services to
the Company in the past fiscal year.

Compensation Committee Interlocks and Insider Participation in Compensation
Decisions

     The Compensation Committee of the Board of Directors is composed of three
outside directors: Messrs. Heilmeier, Malek and Tisch.

            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Compensation Committee of the Board of Directors (the "Committee") is
responsible for setting, on behalf of the Board of Directors, the base salaries
and the total compensation levels of the Chairman and Chief Executive Officer,
the President and Chief Operating Officer, the Senior Vice President and the
Group Presidents of the Employer Services, Brokerage Services and Dealer
Services businesses, as well as a structure for other key executives of the
Company. The Committee grants all stock options and reviews all recommendations
for grants of restricted stock to these and other key executives.

Compensation Policies

     The Company's executive compensation policies for fiscal 2001, which were
reviewed by the Committee, were designed to emphasize both competitive and
variable compensation, with direct linkages to business objectives and
exceptional performance.

                                       13



     The primary components of the compensation package for key executives for
fiscal 2001 were base salary, bonus, restricted stock and stock options. The
Company and the Committee have always believed that stock ownership in the form
of restricted stock and longer-term stock option vesting is vital in linking
management to stockholder interests. The Company sets its salary and bonus
targets (i.e., direct cash compensation) at the median of market range levels of
comparable sized companies in the S&P 500. The Company's executives may derive
more economic benefit from stock option price appreciation, as a percentage of
total compensation, than from base salary and bonus combined. The Committee
generally intends to cause all eligible compensation to be exempt from the
limitations of Section 162(m) of the Code, but reserves the right to make
non-exempt awards where appropriate.

Annual Compensation

     Total annual compensation consists of base salary, cash bonus and yearly
vesting of restricted stock. The base salaries for executives for fiscal 2001
were determined based upon the job grade of the position, the salary range of
the job grade and the performance of the executive.

     Key executives earned cash bonuses in fiscal 2001 based upon individual
annual accomplishments versus individual pre-established goals.

Long-Term Compensation

     Long-term compensation is comprised of restricted stock and the expected
value of stock options. The Company has from time to time sold shares of
restricted stock to executive officers and other key employees, at par value, in
recognition of their individual levels of relative responsibility and
prospective contributions to the business. Company-imposed restrictions on
transfer or pledge of the restricted stock generally lapse over a period of up
to five years, and are subject to continued employment. The restricted stock
plan is designed to encourage stock ownership, longevity and long-term
performance.

     Stock options are granted to executive officers and other key employees in
amounts based upon their job grade and individual performance. Stock options are
granted at fair market value as of the date of grant, and have a term of up to
ten years. Stock options provide incentive for the creation of stockholder value
over the long-term, and also significantly aid in executive recruiting and
retention.

     Restricted stock and stock option grants were made to individual key
executives during fiscal 2001 on a basis consistent with the above guidelines.

Benefits

     The Company provided certain supplemental benefits to key executives during
fiscal 2001 to ensure that it could compete effectively for executive talent.
These supplemental benefits included additional Company-paid life insurance and
certain additional retirement benefits described in the "Defined Benefit Plans"
section of this Proxy Statement.

CEO Compensation

     The Committee meets annually to evaluate the performance of the Chief
Executive Officer and to determine his compensation.

     Mr. Weinbach received a base salary of $721,250 and a bonus of $450,000
during fiscal 2001.  Mr. Weinbach's compensation is based on the satisfaction of
specific performance objectives and the terms of his employment agreement. Mr.
Weinbach's compensation approximates the median base salary and bonus
compensation of chief executive officers at companies in the S&P 500 with annual
revenues between $3 and $12 billion, as surveyed by the Company.

                                       14



     The incentives provided to the Chief Executive Officer are provided in the
form of restricted stock and stock options. This ensures that the Chief
Executive Officer and the Company's stockholders have a commonality of purpose
in enhancing stockholder value.

                            APPROVAL OF AMENDMENT OF THE
                        2000 KEY EMPLOYEES' STOCK OPTION PLAN

     On August 13, 2001, the Board of Directors approved an amendment (the "2000
Plan Amendment") to the 2000 Key Employees' Stock Option Plan (the "2000 Plan"),
which increased the number of shares of the Company's Common Stock that can be
issued under the 2000 Plan by 22,000,000 shares, so that after the 2000 Plan
Amendment the total number of authorized shares that can be issued under the
2000 Plan would be 36,750,000. The 2000 Plan Amendment was effective as of
August 13, 2001, subject to stockholder approval at this meeting.

Summary of the 2000 Plan

     The principal features of the 2000 Plan are summarized below, but such
summary is qualified in its entirety by reference to its full text, a copy of
which is filed with the Securities and Exchange Commission.

     Shares Subject to the 2000 Plan.
     -------------------------------
     As of August 31, 2001, there were no shares of the Company's Common Stock
available for issuance upon the grant of new options under the 1990 Key
Employees' Stock Option Plan (the "1990 Plan")and there were only 1,640,000
shares available for issuance upon the grant of new options under the 2000 Plan.
As of such date, after taking into account the 2000 Plan Amendment, the Company
would have under its stock option plans a total of 71,216,000 shares reserved
for issuance, which reserved shares are allocated as follows: (i) 23,640,000
shares are available for issuance upon the grant of new options under the 2000
Plan; and (ii) 47,576,000 shares are subject to outstanding stock option grants
under the 1990 Plan and the 2000 Plan. Taken together, these reserved shares
represent less than 12% of the aggregate number shares of Common Stock
outstanding.

     Each option granted pursuant to the 2000 Plan shall be in writing and shall
have such terms and conditions not inconsistent with the provisions of the 2000
Plan as the Committee (as defined below) shall provide.

     Exercise Price.
     --------------
     The exercise price under the options shall not be less than the fair market
value (as defined in the 2000 Plan) of the Company's Common Stock on the date
the option is granted. As of August 31, 2001, the fair market value of the
Company's Common Stock was $51.76.

     Eligible Employees.
     ------------------
     Options may be granted to any key employee of the Company or any of its
subsidiaries. There are approximately 9,000 employees eligible to be granted
options under the 2000 Plan. Employees who are also officers or directors of the
Company or its subsidiaries shall not, by reason of holding such offices, be
ineligible to receive options. However, any person who would own, directly or
indirectly, at the time the option is granted to him or her, more than 10% of
the total combined voting power of all classes of stock of the Company or any of
its subsidiaries (a "10% owner") shall only be eligible to receive any incentive
stock options under the 2000 Plan if the option satisfies the requirements of
section 422(c)(5) of the Internal Revenue Code of 1986, as amended (the "Code").

     Rights as a Stockholder and Assignability.
     -----------------------------------------
     An optionee will have no rights as a stockholder with respect to any shares
covered by his or her options untilthe date of issuance of a stock certificate
to the optionee for such shares. During the life of the optionee, the option is
exercisable only by the optionee.

     Duration of Options.
     -------------------
     Options granted under the 2000 Plan shall become exercisable as the
Committee in its discretion may provide upon the granting thereof. Except as
otherwise provided in the applicable award agreement, the unexercised portion of
any option granted under the 2000 Plan shall automatically terminate and expire
on the earliest to occur of (i) ten years (or, in the case of an incentive stock
option ("ISO") under section 422 of the Code, five years with respect to a 10%
owner) from the date of grant, (ii) 60 days after termination of employment (or
such longer period as the Committee may provide in the event of the optionee's
permanent and total disability), (iii) if termination is due to the death of an
optionee during employment or during the period following termination of
employment referred to in clause (ii), six months after the appointment and
qualification of an executor or administrator of the deceased optionee's estate
or twelve months after the death of the optionee,

                                       17



whichever occurs earlier, or (iv) at such earlier time upon the occurrence of
such earlier events as the Committee may provide upon granting of such option.

     Administration of the 2000 Plan.
     -------------------------------
     Except to the extent required in order to qualify for exemptive relief
under Rule 16b-3 or its successor provision under the Securities Exchange Act of
1934,as amended, or to satisfy the requirements for performance-based
compensation under Section 162(m) of the Code, in which case the Board of
Directors of the Company (or a committee appointed by the Board of Directors
which satisfies the requirements of such provisions) shall administer the 2000
Plan, the 2000 Plan shall be administered by a Stock Option Committee (the
"Committee") to be appointed by the Board of Directors of the Company, which
Committee may include members of the Board of Directors and employees of the
Company who are not members of the Board of Directors. The Committee shall have
the authority to determine the employees to whom options will be granted,
whether the options granted shall be incentive stock options or non-qualified
stock options, the number of shares that may be purchased under each option, the
dates options become exercisable and the option price, except that the option
price of each share of Common Stock purchasable under any stock option shall not
be less than 100% of the fair market value thereof at the time the option is
granted. The exercise price for all stock options under the 2000 Plan can be
paid for in cash or with shares of the Company's Common Stock that have been
held for at least six months or previously acquired in the open market or by
delivering to the Committee a copy of irrevocable instructions to a stock broker
to deliver promptly to the Company any amount of loan proceeds, or proceeds of
the sale of the shares subject to the option, sufficient to pay the exercise
price. The Committee shall interpret and generally administer the 2000 Plan.
Options may be granted under the 2000 Plan at any time prior to August 10, 2011,
on which date the 2000 Plan will expire, except as to options then outstanding
under the 2000 Plan. The 2000 Plan may be amended or terminated at any time by
the Board of Directors without stockholder action, provided that any such
amendment is in compliance with all applicable laws and the rules of the New
York Stock Exchange and other exchanges upon which the shares of the Company
are listed. No termination, modification or amendment of the 2000 Plan or any
outstanding agreements which may adversely affect the rights of any optionee may
be made without the consent of the optionee. Provisions are made in the 2000
Plan for appropriate adjustments in the event of changes in the Company's
outstanding Common Stock by reason or merger, stock splits or similar events.
The 2000 Plan also provides that the Committee may, in its sole discretion,
establish procedures whereby optionees may elect to defer the receipt of shares
upon the exercise of an option for a specified time or until the occurrence of a
specified event.

     Incentive Stock Options.
     -----------------------
     The 2000 Plan permits the Company to grant ISOs and contains specific
provisions applicable thereto.


     Non-Qualified Stock Options.
     ---------------------------
     The Committee may grant non-qualified stock options under the 2000 Plan.
The Committee is given the authority to determine the price at which
non-qualified stock options may be granted, which will be no less than the fair
market value of the Company's Common Stock on the day the option is granted.

     Federal Income Tax Consequences Relating to Options.
     ---------------------------------------------------
     The following summary of the federal income tax consequences of the grant
and exercise of non-qualified and incentive stock options awarded under the 2000
Plan, and the disposition of shares of Common Stock purchased pursuant to the
exercise of such stock options, is intended to reflect the current provisions of
the Code and the regulations thereunder. This summary is not intended to be a
complete statement of applicable law, nor does it address foreign, state or
local tax considerations.

     No income will be realized by an optionee upon grant of a non-qualified
stock option. Upon exercise of a non-qualified stock option, the optionee will
recognize ordinary compensation income in an amount equal to the excess, if any,
of the fair market value of the underlying stock over the option exercise price
(the "Spread") at the time of exercise. The Spread will be deductible by the
Company for federal income tax purposes subject to the possible limitations on
deductibility under sections 280G and 162(m) of the Code for compensation paid
to executives designated in those sections. The optionee's tax basis in the
underlying shares acquired by exercise of a non-qualified stock option will
equal the exercise price plus the amount taxable as compensation to the
optionee. Upon sale of the shares received by the optionee

                                       18



upon exercise of the non-qualified stock option, any gain or loss is generally
long-term or short-term capital gain or loss, depending on the holding period.
The optionee's holding period for shares acquired pursuant to the exercise of a
non-qualified stock option will begin on the date of exercise of such option.

     Pursuant to currently applicable rules under Section 16(b) of the Exchange
Act, the grant of an option (and not its exercise) to a person who is subject to
the reporting and short-swing profit provisions under Section 16 of the Exchange
Act (a "Section 16 Person") begins the six-month period of potential short-swing
liability. The taxable event for the exercise of an option that has been
outstanding at least six months ordinarily will be the date of exercise. If an
option is exercised by a Section 16 Person within six months after the date of
grant, however, taxation ordinarily will be deferred until the date which is six
months after the date of grant, unless the person has filed a timely election
pursuant to section 83(b) of the Code to be taxed on the date of exercise.
However, the six month period of potential short-swing liability may be
eliminated if the option grant (i) is approved in advance by the Company's Board
of Directors (or a committee composed solely of two or more non-employee
directors) or (ii) is approved in advance, or subsequently ratified by the
Company's shareholders no later than the next annual meeting of shareholders.
Consequently, the taxable event for the exercise of an option that satisfies
either of the conditions described in clauses (i) or (ii) above will be the date
of exercise.

     The payment by an optionee of the exercise price, in full or in part, with
previously acquired shares of Common Stock will not affect the tax treatment of
the exercise described above. No gain or loss generally will be recognized by
the optionee upon the surrender of the previously acquired shares to the
Company, and shares received by the optionee, equal in number to the previously
surrendered shares, will have the same tax basis as the shares surrendered to
the Company and will have a holding period that includes the holding period of
the shares surrendered. The value of shares of Common Stock received by the
optionee in excess of the number of shares surrendered to the Company will be
taxable to the optionee. Such additional shares will have a tax basis equal to
the fair market value of such additional shares as of the date ordinary income
is recognized, and will have a holding period that begins on the date ordinary
income is recognized.

     The Code requires that, for ISO treatment, shares of Common Stock acquired
through exercise of an ISO cannot be disposed of before two years from the date
of grant and one year from the date of exercise. ISO holders will generally
incur no federal income tax liability at the time of grant or upon exercise of
such options. However, the Spread will be an "item of tax preference" which may
give rise to "alternative minimum tax" liability at the time of exercise. If the
optionee does not dispose of the shares before two years from the date of grant
and one year from the date of exercise, the difference between the exercise
price and the amount realized upon disposition of the shares will constitute
long-term capital gain or loss, as the case may be. Assuming both the holding
periods are satisfied, no deduction will be allowable to the Company for federal
income tax purposes in connection with the grant or exercise of the option. If,
within two years of the date of grant or within one year from the date of
exercise, the holder of shares acquired through the exercise of an ISO disposes
of such shares, the optionee will generally realize ordinary taxable
compensation at the time of such disposition equal to the difference between the
exercise price and the lesser of the fair market value of the stock on the date
of initial exercise or the amount realized on the subsequent disposition, and
such amount will generally be deductible by the Company for federal income tax
purposes, subject to the possible limitations on deductibility under sections
280G and 162(m) of the Code for compensation paid to executives designated in
those sections.

Stockholder Approval Required

     The 2000 Plan Amendment must be approved by the affirmative vote of the
holders of a majority of the shares cast at the meeting of stockholders in order
to be adopted.

     THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE
APPROVAL OF THE AMENDMENT TO THE 2000 KEY EMPLOYEES' STOCK OPTION PLAN AND THE
AUTHORITY TO ISSUE AN ADDITIONAL 22,000,000 SHARES OF COMMON STOCK THEREUNDER.

                                       19



                                    PROPOSAL 3

                     APPROVAL OF AUTOMATIC DATA PROCESSING, INC.
                     2001 EXECUTIVE INCENTIVE COMPENSATION PLAN

     Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code") generally does not allow publicly held companies to obtain tax
deductions for compensation of more than $1 million paid in any year to their
chief executive officer, or any of their other four most highly compensated
executive officers ("Named Executive Officers"), unless such payments are
"performance-based" in accordance with conditions specified under Section 162(m)
of the Code and the Treasury Regulations promulgated thereunder ("Section
162(m)"). One of those conditions requires the Company to obtain stockholder
approval of the material terms of the Plan (as defined below).

     The Board of Directors of the Company (the "Board") has adopted, and in
this proposal is recommending that the stockholders approve, the Automatic Data
Processing, Inc. 2001 Executive Incentive Compensation Plan (the "Plan") as
described below. Subject to such approval, and if the applicable performance
goals are satisfied, this proposal would enable the Company to pay
performance-based compensation to Named Executive Officers of the Company and to
obtain tax deductions for such payments, without regard to the limitations of
Section 162(m). Further, the Board is requesting stockholder authorization of
shares of the Company's Common Stock for issuance under the Plan (see section
below entitled "Shares Available for Grant").

Summary of the Plan

     The following description of the Plan is only a summary of certain
provisions thereof and is qualified in its entirety by reference to its full
text, a copy of which is filed with the Securities and Exchange Commission.

     Purpose.
     -------
     The purpose of the Plan is to establish an incentive compensation
program for certain executive employees of the Company and its subsidiaries and
divisions who have significant responsibility for the success and growth of the
Company and to assist in attracting, motivating and retaining executive
employees on a competitive basis. The Plan permits the Company to grant annual
incentives ("Bonus Awards") and performance-based restricted stock awards
("Restricted Stock Awards") (collectively referred to herein as "Awards") to
certain executive employees who make substantial contributions to the Company
and/or its subsidiaries and divisions.

     Administration.
     --------------
     The Plan is administered by a committee (the "Committee") that is selected
by the Board and is composed of two or more members of the Board, each of whom
is required to be an "outside director" (within the meaning of Section 162(m)).
The Committee has all the authority that may be necessary or helpful to enable
it to discharge its responsibilities with respect to the Plan. Except as
otherwise specifically limited in the Plan, the Committee has full power and
authority to construe, interpret and administer the Plan.

     Effective Date.
     --------------
     The Plan is effective as of July 1, 2001, subject to approval of the
stockholders, as requested herein.

     Eligibility.
     -----------
     The Plan provides that the Committee shall designate for each period during
which performance is measured the level of attainment of an Award ("Performance
Period") for which executive employees of the Company and its subsidiaries or
divisions, if any, will be eligible ("Participants"). There are approximately
ten employees eligible to participate in the Plan.

     Awards and Performance Goals.
     ----------------------------
     The Committee may establish for each Performance Period the target Bonus
Award and the number of shares of a Restricted Stock Award eligible to vest
(and, if the Committee so determines, a threshold Award Bonus or percentage of
vested shares) with respect to each Award. Further, the Committee shall
establish goals relating to Company, subsidiary, divisional, departmental and/or
functional performance for each Participant (the "Performance Goals") and

                                       20



communicate such Performance Goals to each Participant prior to or during the
applicable Performance Period.  Participants will earn Bonus Awards and/or vest
in Restricted Stock Awards based upon the level of attainment of the applicable
Performance Goals during the applicable Performance Period, as and to the extent
established by the Committee.

     The Performance Goals for the Participants will be based on attainment of
specific levels of performance of the Company (or of a subsidiary, division,
department or function thereof) with reference to one or more of the following
criteria: (i) earnings per share; (ii) stock price; (iii) shareholder return;
(iv) return on investment; (v) return on capital; (vi) earnings before interest,
taxes, depreciation and amortization; (vii) gross or net profits; (viii) gross
or net revenues; (ix) client retention; or (x) any combination of the foregoing.
In calculating the attainment of the Performance Goals, unless determined
otherwise by the Committee prior to the applicable Performance Period, the
Committee shall exclude significant unusual or one-time changes or income,
including gains and losses resulting from divestitures and acquisitions.

     As soon as practicable following the end of the applicable Performance
Period, the Committee will certify the attainment of the Performance Goals and
will calculate the payment amount or vested percentage with respect to each
Award, if any, payable or vested with respect to each Participant. In no event
will any payment or vesting occur with respect to any Award for a Performance
Period in which performance fails to attain or exceed the minimum level for the
applicable Performance Goals.

     Bonus Awards.
     ------------
     The Committee may establish for each Performance Period a target Bonus
Award that may be earned by each Participant (which may be expressed in terms of
a dollar amount, percentage of salary or any other measurement). Bonus Awards
will be paid in a lump sum cash payment, as soon as practicable following the
determination of the amount thereof by the Committee.  The Committee retains the
right to reduce any Bonus Award, in its discretion. The maximum amount of any
Bonus Award payable to a Participant in respect of a single Performance Period
is $2,000,000.

     Restricted Stock Awards.
     -----------------------
     The Committee may grant for each Performance Period a Restricted Stock
Award to any Participant. Each Participant who is granted a Restricted Stock
Award will be required to enter into an agreement with the Company, in a form
specified by the Committee, agreeing to the terms and conditions of the Award
and such other matters consistent with the Plan as the Committee determines
appropriate (an "Agreement").

     Payment for the shares of Common Stock purchased under any Restricted Stock
Award ("Restricted Shares") must be made to the Company as provided for in the
Agreement, at a price determined by the Committee, in its sole discretion. No
fees or commissions are applicable to purchases of Restricted Shares under the
Plan. The maximum number of Restricted Shares that may be granted to a
Participant in a single fiscal year is 200,000.

     In its sole discretion, the Committee will determine the Performance Goals
required for each Participant to vest in his or her Restricted Stock Award. Upon
a Participant's vesting with respect to Restricted Shares, all restrictions
against transfer shall lapse with respect to such shares. Prior to vesting,
Participants may not assign, alienate, pledge, attach, sell or otherwise
transfer or encumber any Restricted Shares.

     The Participant may, as provided in his or her Agreement, have the entire
beneficial ownership of all rights and privileges of a stockholder with respect
to the Restricted Shares awarded to him or her, including the right to receive
dividends and vote such Restricted Shares.

     In the event of any stock dividend, extraordinary cash dividend,
recapitalization, reorganization, merger, consolidation, split-up, spin-off,
combination, exchange of shares, warrants or rights offering to purchase shares
of Common Stock at a price substantially below fair market value, or other
similar corporate event that affects the shares of Common Stock granted or made
available for issuance under the Plan, then the Committee may, in such manner as
it deems equitable, adjust the number and kind of Restricted Shares.

     Market Value of the Common Stock.
     --------------------------------
     On August 31, 2001, the closing price of one share of Common Stock on the
New York Stock Exchange was $51.76.

                                       21



     Shares Available for Grant.
     --------------------------
     The Plan provides that the total number of Restricted Shares that may be
issued under the Plan will not exceed, in the aggregate, 3,500,000.

     Amendment to Plan.
     -----------------
     The Committee may amend, suspend or terminate the Plan at any time;
provided that no amendment may be made without the approval of the Company's
stockholders if the effect of such amendment would be to cause outstanding or
pending Awards to cease to qualify for the performance-based compensation
exception to Section 162(m).

     Withholding.
     -----------
     With respect to any payments made to Participants under the Plan, the
Company will have the right to withhold any taxes required by law to be withheld
because of such payments.

     New Plan Benefits.
     -----------------
     Because amounts payable under the Plan are set at the discretion of the
Committee and are based on satisfaction of Performance Goals in each applicable
Performance Period, it cannot be determined at this time what amounts, if any
will be received by any Participants with respect to the 2002 fiscal year under
the Plan.


Stockholder Approval Required

     The Treasury Regulations promulgated under Section 162(m) require the
affirmative vote of the holders of a majority of the votes cast at the meeting
of stockholders to approve the Plan.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE APPROVAL OF THE
AUTOMATIC DATA PROCESSING, INC. 2001 EXECUTIVE INCENTIVE COMPENSATION PLAN.

                                       22



                             AUDIT COMMITTEE REPORT


     The Audit Committee of the Board of Directors (the "Committee") is
comprised of the four directors named below. Each member of the Committee is an
independent director as defined by New York Stock Exchange rules. The Committee
has adopted a written charter which has been approved by the Board of Directors,
and which is set forth in Appendix A of this Proxy Statement. The Committee has
reviewed and discussed the Company's audited financial statements with
management, which has primary responsibility for the financial statements.
Deloitte & Touche LLP, the Company's independent auditors for fiscal 2001, is
responsible for expressing an opinion on the conformity of the Company's audited
financial statements with generally accepted accounting principles. The
Committee has discussed with Deloitte & Touche LLP the matters that are required
to be discussed by Statement on Auditing Standards No. 61 (Communication With
Audit Committees). Deloitte & Touche LLP has provided to the Committee the
written disclosures and the letter required by Independence Standards Board
Standard No. 1 (Independence Discussions with Audit Committees), and the
Committee discussed with Deloitte & Touche LLP the firm's independence. The
Committee also considered whether Deloitte & Touche LLP's provision of non-audit
services, including financial information systems design and implementation
services, to the Company and its affiliates is compatible with Deloitte & Touche
LLP's independence.


     Based on the considerations referred to above, the Committee recommended to
the Board of Directors that the audited financial statements be included in the
Company's Annual Report on Form 10-K for fiscal 2001 and that Deloitte & Touche
LLP be appointed independent auditors for the Company for fiscal 2002.

                                       Audit Committee
                                       of the Board of Directors


                                       Harvey M. Krueger, Chairman
                                       Joseph A. Califano, Jr.
                                       Leon G. Cooperman
                                       Ann Dibble Jordan

                                       23



                             INDEPENDENT AUDITORS FEES

     In addition to retaining Deloitte & Touche LLP to audit the consolidated
financial statements for fiscal 2001, the Company and its affiliates retained
Deloitte & Touche LLP, as well as other accounting and consulting firms, to
provide various consulting services in fiscal 2001, and expect to continue to do
so in the future. The aggregate fees billed for professional services by
Deloitte & Touche LLP in 2001 for these various services were:

Audit Fees:  $1.1 million for services rendered for the annual audit of the
Company's consolidated financial statements for fiscal 2001 and the quarterly
reviews of the financial statements included in the Company's Forms 10-Q;

Financial Information Systems Design and Implementation Fees: $3.5 million for
services rendered in connection with the design or implementation of hardware or
software systems that aggregate source data underlying the financial statements
or generate information that is significant to the financial statements taken as
a whole; and

All Other Fees:  $5.9 million for all other services consisting  primarily of
tax services, non-financial statement audit services, information technology
consulting and assistance for systems not associated with the financial
statements.

     Although the Company expects to continue to retain Deloitte & Touche LLP
and other firms to assist in the design and implementation of its financial
information systems, the Company's managers make all management decisions with
respect to such systems, and are responsible for evaluating the adequacy of such
systems and for establishing and maintaining the Company's system of internal
accounting controls.


                                     PROPOSAL 4

                               APPOINTMENT OF AUDITORS

     At the Annual Meeting of Stockholders, the stockholders will vote on the
ratification of the appointment of Deloitte & Touche LLP, certified public
accountants, as independent auditors to audit the accounts of the Company and
its subsidiaries for the fiscal year begun July 1, 2001. Deloitte & Touche LLP
is a member of the SEC Practice Section of the American Institute of Certified
Public Accountants. A representative of Deloitte & Touche LLP will be present at
the Annual Meeting of Stockholders and will have an opportunity to make a
statement if he or she desires. He or she will be available to answer
appropriate questions.

     THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE
RATIFICATION OF THE APPOINTMENT OF THE AUDITORS.

                                    OTHER MATTERS

     So far as the Board of Directors is aware, only the aforementioned matters
will be acted upon at the meeting. If any other matters properly come before the
meeting, the accompanying proxy may be voted on such other matters in accordance
with the best judgment of the person or persons voting said proxy.

                SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     During the fiscal year ended June 30, 2001, no directors or officers
submitted late filings under Section 16(a) of the Exchange Act.

                                 STOCKHOLDER PROPOSALS

     Stockholder proposals intended to be presented at the 2002 Annual Meeting
must be received by the Company for inclusion in the 2002 Proxy Statement no
later than May 27, 2002.

     Stockholder proposals intended to be presented at the 2002 Annual Meeting,

                                       24



                                  ANNUAL REPORT

     The Company's Annual Report for the fiscal year ended June 30, 2001, which
is not a part of the proxy soliciting material, is being mailed to the Company's
stockholders together with this Proxy Statement.

               ELECTRONIC ACCESS TO PROXY MATERIALS AND ANNUAL REPORT

     This Proxy Statement and the Company's Annual Report may be viewed online
at www.adp.com. Stockholders of record may elect to view future proxy statements
and annual reports over the Internet rather than receiving paper copies in the
mail and can thereby save the Company the cost of producing and mailing these
documents. If you vote your shares over the Internet this year, you will be
given the opportunity to choose electronic access at the time you vote. You can
also choose electronic access by following the instructions that you will
receive in connection with next year's annual meeting of stockholders.
Stockholders who choose electronic access will receive an e-mail next year
containing the Internet address to use to access the proxy statement and annual
report. Your choice will remain in effect until you cancel it. You do not have
to elect Internet access each year.

        IMPORTANT NOTICE REGARDING DELIVERY OF SECURITY HOLDER DOCUMENTS

     Please see the enclosed separate notice regarding delivery of security
holder documents.

     The SEC issued a new rule that became effective December 4, 2000 regarding
the delivery of proxy statements and information statements to households. This
rule is intended to complement a ruling on the delivery of disclosure documents
to households that was issued on December 20, 1999. Together these rules spell
out the conditions under which annual reports, information statements, proxy
statements, prospectuses and other disclosure documents of a particular company
that would otherwise be mailed in separate envelopes to more than one person at
a shared address may be mailed as one copy in one envelope addressed to all
holders at that address. In accordance with that rule, the Company will begin
"householding" all such disclosure documents effective December 1, 2001.

     If you are a registered shareholder and you choose not to have the
aforementioned disclosure documents sent to a single household address as
described above, you must "opt-out" by marking the designated box on the
enclosed proxy card. If you choose to "opt-out" of the householding program at a
future date, please write to ADP Investor Communication Services, Sharelink
Department, 51 Mercedes Way, Edgewood, New York 11717 or call (631) 254-7637 and
we will cease householding all such disclosure documents within 30 days. If we
do not receive instructions to remove your account(s) from this service, your
account(s) will continue to be "householded" until we notify you otherwise.

     If you own the Company's Common Stock in nominee name (such as through a
broker), information regarding householding of disclosure documents should be
forwarded to you by your broker.

                         AUTOMATIC DATA PROCESSING, INC.

                             AUDIT COMMITTEE CHARTER

I.     Purpose

       The primary functions of the Audit Committee are to assist the Board of
Directors in fulfilling its oversight responsibilities with respect to: (i) the
Company's systems of internal controls regarding finance, accounting, legal
compliance and ethical behavior; (ii) the Company's auditing, accounting and
financial reporting processes generally; and (iii) the Company's annual audited
financial statements. Consistent with these functions, the Committee will
encourage continuous improvement of, and foster adherence to, the Company's
policies, procedures and practices at all levels.

       In meeting its oversight responsibilities, the Committee is expected
to:

       o  Serve as an independent and objective party to oversee the
          appropriateness of the Company's financial reporting processes and
          internal control systems.

       o  Review the audit activities of the Company's outside auditors and
          Corporate Audit Department.

       o  Provide an open avenue of communications among the outside auditors,
          financial and senior management, the Corporate Audit Department, and
          the Board of Directors.

       Without limiting the foregoing, and in recognition of the fact that the
Company's outside auditors are ultimately accountable to the Board of Directors
and the Committee, the Board of Directors and the Committee have the ultimate
authority and responsibility to select, evaluate and (where appropriate) replace
the outside auditors, and/or to nominate the outside auditors for shareholder
approval.

       The Committee will primarily fulfill these responsibilities by carrying
out the activities enumerated in Section IV of this Charter.

II.    Organization

       The Audit Committee shall be comprised of three or more directors as
determined by the Board of Directors, each of whom shall be independent of the
Management, and free from any relationship that, in the opinion of the Board,
would interfere with the exercise of the director's independence from the
Management and the Company. Each Committee member shall satisfy the further
restrictions set forth on Annex I to this Charter.

       All Committee members shall have a working familiarity with basic
finance and accounting practices, and at least one Committee member shall have
accounting or related financial management expertise.

       Committee members shall be elected by the Board at the annual
organizational meeting of the Board of Directors; members shall serve until
their successors shall be duly elected and qualified. The Committee's Chairman
shall be designated by the full Board or, if it does not do so, the Committee
members shall elect a Chairman by vote of a majority of the full Committee.

III.   Meetings

       The Audit Committee shall meet four times per year on a quarterly basis,
or more frequently as circumstances require. The Committee shall require members
of Management, the Corporate Audit Department, the outside auditors and others
to attend meetings and to provide pertinent information, as necessary. As part
of its job to foster open communications, the Committee shall meet in separate
executive sessions during each of its four regularly scheduled meetings with
the head of the Corporate Audit Department and the Company's outside auditors to
discuss any matters that the Committee (or either of these groups) believes
should be discussed privately. The annual reoccurring required agenda

                                       A-1



items for each of the Committee's four regularly scheduled meetings are set
forth on Annex II to this Charter. Additional matters will be added to each
meeting's agenda at the request of the Committee, Management, the Corporate
Audit Department, and/or the outside auditors.

IV.    Responsibilities and Duties

       To fulfill its responsibilities and duties, the Audit Committee shall:

       1.  Review the performance of the Company's outside auditors and
           Management's recommendation as to the selection, retention or
           discharge of the outside auditors to serve as the Company's
           independent auditors. The Committee shall make recommendations to the
           Board of Directors regarding the appointment or replacement of the
           outside auditors.

       2.  On an annual basis, review and discuss with the outside auditors all
           relationships the outside auditors have with the Company in order to
           evaluate the outside auditors' continued independence. The Committee:
           (i) shall ensure that the outside auditors submit to the Committee on
           an annual basis a written statement delineating all such
           relationships; and (ii) shall discuss with the outside auditors any
           disclosed relationship or services that may impact the objectivity
           and independence of the outside auditors.

       3.  Review the outside auditors' and the Corporate Audit Department's
           audit plan for each fiscal year, and report to the Board of Directors
           the Committee's agreement or disagreement with the scope of each such
           fiscal year audit plan.

       4.  Have a predetermined arrangement with Management and the outside
           auditors that the Committee's Chairman will be advised of any
           significant matters in the interim quarterly financial statements
           prior to the Company's issuance of its applicable press release, and
           that following the completion of the quarterly review performed by
           the outside auditors the Committee will receive, prior to the
           Company's filing of its applicable Form 10-Q, a report from the
           outside auditors on their findings.

       5.  Review the Company's annual financial statements with the outside
           auditors and Management, and report the same to the Board of
           Directors and recommend their inclusion in the Company's Form 10-K
           for the applicable fiscal year.

       6.  Periodically discuss with the outside auditors their judgments about
           the quality, appropriateness, and acceptability of the Company's
           accounting principles and financial disclosure practices, as applied
           in its financial reporting.

       7.  Inquire about the application of the Company's accounting policies
           and its consistency from period to period, and the compatibility of
           these accounting policies with generally accepted accounting
           principles, and (where appropriate) the Company's provisions for
           future occurrences which may have a material impact on the financial
           statements of the Company.

       8.  Review the Company's processes of assessing the risk of fraudulent
           financial reporting and the program that Management has established
           to monitor compliance with its Code of Corporate Responsibility and
           the Code of Corporate Conduct.

       9.  Obtain explanations from Management for unusual variances in the
           Company's annual financial statements from year to year, and review
           annually the auditor's letter of the recommendations to Management
           and Management's response.

      10.  Review any significant proposed changes in the Company's accounting
           policies with the outside auditors and Management.

      11.  Review the adequacy of the Company's financial and administrative
           controls, procedures and practices with the outside auditors,
           Management and the Corporate Audit Department.

      12.  Inquire of Management, the Corporate Audit Department and the outside
           auditors if there were any significant reporting, accounting or
           auditing issues during the relevant fiscal period and, if so, how
           they were resolved.

                                       A-2



      13.  Periodically consult with the outside auditors without Management
           being present about the Company's financial statements.

      14.  Review the fees of the outside auditors and the scope of non-audit
           services performed by such auditors.

      15.  Review any Management decision to seek a second opinion from
           independent auditors other than the Company's regular outside
           auditors with respect to any significant accounting issue.

      16.  Review with Management and the outside auditors the sufficiency and
           quality of the Corporate Audit Department staff and other financial
           and accounting personnel of the Company.

      17.  Meet with the head of the Corporate Audit Department and the outside
           auditors lead partner on a regular basis and maintain direct lines of
           communication with the head of the Corporate Audit Department and the
           outside auditors.

      18.  Review with the Company's counsel, material pending litigation, legal
           compliance matters or other any legal matter that could have a
           significant impact on the Company's financial statements.

      19.  Prepare any Committee reports required by applicable securities laws
           or stock exchange listing requirements or rules to be included in any
           proxy statements, information statements or other documents.

      20.  Review and reassess the adequacy of this Charter annually and
           recommend to the Board any changes the Committee deems appropriate.

      21.  Perform any other activities consistent with this Charter, the
           Company's By-laws and governing law, as the Committee or the Board
           deems appropriate.

                                     Annex I

     Further restrictions and conditions on Audit Committee membership:

     (a) Employees. A director who is an employee (including non-employee
executive officers) of the Company or any of its affiliates may not serve on the
Committee until three years following the termination of his or her employment.
In the event the employment relationship is with a former parent or predecessor
of the Company, the director may serve on the Committee after three years
following the termination of the relationship between the Company and the former
parent or predecessor.

     (b) Business Relationship. A director (i) who is a partner, controlling
shareholder or executive officer of an organization that has a business
relationship with the Company or (ii) who has a direct business relationship
with the Company (e.g., a consultant) may serve on the Committee only if the
Board determines in its business judgment that the relationship does not
interfere with the director's exercise of independent judgment. In making a
determination regarding the independence of a director, the Board should
consider (among other things) the materiality of the relationship to the
Company, to the director, and, if applicable, to the organization with which the
director is affiliated.

     "Business relationships" can include commercial, industrial, banking,
consulting, legal, accounting and other relationships. A director can have this
relationship directly with the Company, or the director can be a partner,
officer or employee of an organization that has such a relationship. The
director may serve on the Committee without the Board's determination after
three years following the termination of, as applicable, either (1) the
relationship between the organization with which the director is affiliated and
the Company, (2) the relationship between the director and his or her
partnership status, shareholder interest or executive officer position, or (3)
the direct business relationship between the director and the Company.

     (c) Cross-Compensation Committee Link. A director who is employed as an
executive of another corporation where any of the Company's executives serve on
that corporation's compensation committee may not serve on the Committee.

     (d) Immediate Family. A director who is an Immediate Family member of an
individual who is an executive officer of the Company or any of its affiliates
cannot serve on the Committee until three years following the termination of
such employment relationship. See para. 303.02 of the NYSE Listed Company Manual
for the definition of "Immediate Family."
