                        (as amended on May 14, 2002)

     The purpose of this Supplemental Officers Retirement Plan (the "Plan")
is to provide an additional means by which AUTOMATIC DATA PROCESSING, INC. may
attract, retain and encourage the productive efforts of a select group of
corporate vice presidents and more senior corporate officers who provide
valuable services to AUTOMATIC DATA PROCESSING, INC. and its subsidiaries. The
Plan provides supplemental retirement benefits to qualifying participants.

     The Plan is as follows:

                                     ARTICLE I

     The following terms when used in this Plan shall have the designated
meaning, unless a different meaning is clearly required by the context.

     1.1      Annual Plan Benefit.  The Annual Plan Benefit shall be the annual
              --------------------

total compensation actually paid or accrued by the Company to or for a
Participant (including, without limitation, bonuses paid or accrued,
performance incentive payments and the like and restricted stock plans), and
excluding relocation pay, compensation derived from stock options, and stock

payment, shall be included in Participant's compensation. The Company's chief
executive officer shall determine the deemed value of any stock option grant
made in lieu of a bonus payment, which value shall not, in any event, be: (i)
greater than the "target bonus" amount the stock option grant was made in lieu
of (the "Substituted Amount") or (ii) less than the amount such Participant
would have received had the foregoing stock option grant not been made and the
normal bonus "scoring" methodology been applied to the Substituted Amount,
provided that such amount shall not exceed the Substituted Amount. The deemed
value of such stock option grant shall be included in a Participant's
compensation in the calendar year in which the bonus (which the stock option was
granted in lieu of) would have otherwise been paid. The value (on the date that
restrictions lapse) of a Participant's restricted stock with restrictions
lapsing during the Company's fiscal year that begins during the applicable
calendar year shall be included in the Participant's compensation for such

or otherwise. A Participant's Private Sector Plan Benefits shall be expressed
as an annual amount in the form of an actuarially equivalent straight life
annuity starting at his Normal Retirement Date.

                                  ARTICLE II
                                 ELIGIBILITY
                                 ------------

     (a)     The Committee may at any time and from time to time (but
prospectively only) designate any corporate vice president or any more senior
corporate officer of the Company as a Participant in the Plan; provided that
such person participates to the maximum extent permissible in the Company's
other retirement plans (including, without limitation, the Automatic Data
Processing, Inc. Retirement and Savings Plan and the Automatic Data Processing,
Inc. Pension Retirement Plan) during the entire period he is a Participant in
the Plan.

     (b)     A person shall automatically cease to be a Participant on the
earlier to occur of the date on which: (i) he is no longer a corporate vice
president or a more senior corporate officer of the Company; or (ii) he ceases
to participate to the maximum extent permissible in

                                    -4-

<PAGE>

the Company's retirement plans (including, without limitation, the Automatic
Data Processing, Inc. Retirement and Savings Plan and the Automatic Data
Processing, Inc. Pension Retirement Plan).

                                    ARTICLE III
                                RETIREMENT BENEFITS
                                -------------------

     3.1     In General.

     (a)     A Participant's Annual Plan Benefit is the product of (i) his
Final Average Annual Pay, (ii) his Future Service period, (iii) the Annual
Benefit Multiplier and (iv) his Vested Percentage; provided that, in no event,
may the Participant's Annual Plan Benefit exceed the Maximum Annual Benefit
Limitation applicable to him.

     (b)     In addition, the Annual Plan Benefits otherwise payable to a
Participant under the Plan's basic benefit formula set forth in Section 3.1(a)
above shall be reduced to the extent necessary to cause the total of (i)
Participant's Annual Plan Benefits and (ii) Participant's annual Other
Retirement Benefits not to exceed 60% of Participant's Final Average Annual Pay.

     (c)     A Participant's benefits under this Plan shall be expressed as an
annual amount in the form of a straight life annuity or, at the Committee's
election, another actuarially equivalent payment option, starting as at the date
the payments to such Participant under this Article III begin.

     3.2     Normal Retirement Benefit. If a Participant wishes to receive Plan
             --------------------------
benefits on and after his Normal Retirement Date, the Company will pay the
Participant a monthly benefit, starting on the first of the month after Normal
Retirement Date and ending with the payment for the month in which his death
occurs; provided that no benefit shall be paid hereunder unless and until such
Participant has ceased to be employed by the Company. Such monthly benefit shall
be
                                       -5-

<PAGE>

one-twelfth of such Participant's Annual Plan Benefit determined in accordance
with the provisions of Section 3.1 above.

     3.3     Early Retirement Benefit. If a Participant wishes to receive Plan
             -------------------------
benefits commencing on or after his Early Retirement Date and before his Normal
Retirement Date, the Company will, at Participant's request, pay the Participant
a monthly benefit starting on the first of the month after his Early Retirement
Date after which he requested that he begin receiving benefits under the Plan
and ending with the payment for the month in which his death occurs; provided
that no benefit shall be paid hereunder unless and until such Participant has
ceased to be employed by the Company. Such monthly benefit shall be in an amount
equal to the product of the monthly benefit the Participant would have received
under Section 3.2 if the Participant had elected to commence receiving payments
under the Plan on his Normal Retirement Date, actuarially reduced to reflect the
commencement of the payment of Plan benefits before his Normal Retirement Date.
The Committee may, in its discretion, reduce a Participant's Plan benefits by
less than a straight actuarially reduced amount if Participant begins to receive
Plan benefits after his Early Retirement Date and before his Normal Retirement
Date.

     3.4     Disability Retirement Benefit. If a Participant shall incur a
             ------------------------------
Disability while employed by the Company, the Company shall pay such Participant
a monthly benefit starting on the first day of the calendar month after the date
his Disability begins and ending with the payment for the calendar month in
which his death occurs or his disability ends, whichever occurs first. Such
monthly benefit (which shall not be reduced by, and shall not reduce, the
benefits, if any, payable to a Participant under the Company's Long Term
Disability Insurance Program) shall be calculated in the same way as an Early
Retirement benefit under Section 3.3, based on his Final Average Annual Pay when
his Disability begins (which will, for purposes of this Section 3.4 only, be
determined over less than five full consecutive calendar years to the extent
that his Future Service period is less than five years), except that (i) the
Vested Percentage

                                       -6-

<PAGE>

shall always be 100%, (ii) there shall not be any actuarial reduction to reflect
the commencement of the payment of benefits before his Normal Retirement Date,
and (iii) there shall not be any Future Service period accrual during his
Disability. For purposes of this Section 3.4, "Disability" shall have the same
meaning, and shall be determined in the same manner, as it is determined under
the Company's Long Term Disability Insurance Program as in effect on the date
the Disability begins.

     3.5     No Duplication.  In no event shall benefits become payable to any
             ---------------
Participant under more than one Section of this Article III.


                                    ARTICLE IV
                                    FORFEITURES
                                    -----------

     4.1     Forfeiture for Competitive Employment. If a Participant violates
             --------------------------------------
the non-competition provisions of any agreement he has entered into with the
Company after his employment terminates, or if his employment with the Company
is terminated on account of his dishonesty or gross negligence, such Participant
shall forever and irrevocably forfeit all benefits otherwise due him under the
terms of the Plan.

     4.2     Limitation. If any provision of this Article IV shall be
             -----------
unenforceable as a matter of law, it shall be construed to apply to the greatest
extent permitted by law so as to give effect to its intended purposes.

                                     ARTICLE V
                          CONDITIONS RELATED TO BENEFITS
                          -------------------------------

     5.1     Administration of Plan. The Committee shall administer the Plan and
             -----------------------
shall have the sole and exclusive authority to interpret, construe and apply its
provisions. The Committee shall have the power to establish, adopt and revise
such rules and regulations as it may deem

                                    -7-

<PAGE>

necessary or advisable for the administration of the Plan and the operation of
the Committee's activities in connection therewith. All decisions of the
Committee shall be by vote or written consent of the majority of its members
and shall be final and binding. Members of the Committee shall be eligible to
participate in the Plan while serving as a member of the Committee, but a
member of the Committee shall not vote or act upon any matter which relates
solely to such member in his capacity as a Participant.

     5.2     Grantor Trust. The Committee may, at its discretion, have the
             -------------
Company create a grantor trust (within the meaning of section 671 of the Code)
in connection with the adoption of this Plan to which it may from time to time
contribute amounts to accumulate an appropriate reserve against its obligations
hereunder. Notwithstanding the creation of such trust, the benefits hereunder
shall be a general obligation of the Company. Payment of benefits from such
trust shall, to the extent, discharge the Company's obligations under this Plan.
A Participant shall have only a contractual right as a general creditor of the
Company to the amounts, if any, payable hereunder and such right shall not be
secured by any assets of the Company or the trust.

     5.3     No Right to Company Assets. Neither a Participant nor any other
             ---------------------------
person shall acquire by reason of the Plan any right in or title to any assets,
funds or property of the Company whatsoever including, without limiting the
generality of the foregoing, any specific funds or assets which the Company may
set aside in anticipation of a liability hereunder, nor in or to any policy or
policies of insurance on the life of a Participant owned by the Company.

     5.4     No Employment Rights. Nothing herein shall constitute a contract
             --------------------
of continuing employment or in any manner obligate the Company to continue the
service of a Participant, or obligate a Participant to continue in the service
of the Company, and nothing herein shall be construed as fixing or regulating
the compensation paid to a Participant.

     5.5     Company's Right to Terminate and Amend. The Company reserves the
             ---------------------------------------
right in its sole discretion at any time to amend the Plan in any respect or
terminate the Plan.

                                   -8-

<PAGE>

Notwithstanding the foregoing, no such amendment or termination shall reduce the
amount of the benefit theretofore vested by any Participant or change the
conditions required to be satisfied to receive payment of such past accrued
benefit based on the provisions of the Plan as theretofore in effect. For this
purpose, the amount of a Participant's accrued benefit as of the date of any
plan amendment or termination shall be determined as if the Participant was
then retiring in accordance with Section 3.3 with his actual Vested Percentage
accrued as at such date; provided that if the Company is terminating the Plan
and if a Participant has not completed at least 5 years of Future Service,
Participant's Vested Percentage shall be (i) 40% if he has completed 4 years of
Future Service, (ii) 30% if he has completed 3 years of Future Service, (iii)
20% if he has completed 2 years of Future Service, (iv) 10% if he has completed
1 year of Future Service, and (v) 0% if he has not completed 1 year of Future
Service.

     5.6     Protective Provisions.  The Participant shall cooperate with the
             ----------------------
Company by furnishing any and all information requested by the Company in order
to facilitate the payment of benefits hereunder.

     5.7     Right of Offset. If at the time any payment is to be made hereunder
             ----------------
a Participant is indebted to the Company or otherwise subject to a monetary
claim by the Company, the payments remaining to be paid to the Participant under
the Plan may, at the Company's discretion, be reduced by setoff against the
amount of such indebtedness or claim.

     5.8     No Third Party Rights. Nothing in this Plan or any trust
established pursuant to Section 5.2 hereof shall be construed to create any
rights hereunder in favor of any person (other than the Company and any
Participant) or to limit the Company's right to amend or terminate the Plan in
any manner subject to Section 5.5 hereof.

                                    -9-

the same shall be valid, nor shall any such benefit or payment be in any way
liable for or subject to the debts, contracts, liabilities, engagements or torts
of any Participant or subject to levy, garnishment, attachment, execution or
other legal or equitable process. No part of the amounts payable shall, prior to
actual payment, be subject to seizure or sequestration for the payment of any
debts, judgments, alimony or separate maintenance owed by a Participant, nor be
transferable by operation of law in the event of a Participant's bankruptcy or
insolvency.

     6.2    Withholding. To the extent required by law the Company shall be
            -----------
entitled to withhold from any payments due hereunder any federal, state and
local taxes required to be withheld in connection with such payment.

     6.3     Gender and Number.  Wherever appropriate herein, the masculine
             ------------------
shall mean the feminine and the singular shall mean the plural or vice versa.

     6.4     Notice. Any notice required or permitted to be made under the Plan
             -------
shall be sufficient if in writing and hand delivered, or sent by registered or
certified mail, to (a) in the case of notice to the Company or the Committee,
the principal office of the Company, directed to the attention of the Secretary

             ---------------
accordance with the laws of the State of New Jersey.

         In the event of the death of a participant who is at least 35 years of
age at the time of his death and who is vested in accordance with the provisions
of Paragraph 1.18, the surviving spouse is entitled to receive 50% of the death
benefit which the participant would have been entitled to receive at the time of
his death. Such benefit shall be payable monthly as a straight life annuity

participant would have been entitled to at the normal retirement age of 65 or,
at the election of the spouse, in accordance with the early retirement
provision actuarily reduced.
