selected by the Participant under the Wyeth Retirement Plan. Notwithstanding the
foregoing, a Participant may select any optional form of payment available under
the Wyeth Retirement Plan. If a Plan Benefit is payable in a form other than a
Single Life Annuity over the life of the Participant, such Plan Benefit shall be
subject to adjustment by the same actuarial equivalent factors as are applied
under the Wyeth Retirement Plan with respect to the Wyeth Retirement Plan
benefit of the Participant to determine Actuarial Equivalence. Any election made
by a Participant pursuant Section 4 shall be in writing in a form acceptable to
the Retirement Committee and filed at least six (6) months prior to his/her
retirement.
         Effective as of April 1, 2001, an election by a Participant to receive
a lump sum distribution of his or her benefit under the Plan shall only be
effective six (6) months after the date of his or her retirement (and effective

"Deferral Period"). The plan benefit of a Participant shall be credited with
interest on a quarterly basis during the Deferral Period using the same interest
rate as that rate being used to determine the value of the Refund Feature under
the Wyeth Retirement Plan on the date of the commencement of the Deferral
Period. Such interest rate shall be adjusted during the Deferral Period to
reflect changes in the interest rate being used to determine the value of the
Refund Feature under the Wyeth Retirement Plan. In the event a Participant dies
during the Deferral Period, his or her plan benefit shall be paid to his or her
designated beneficiary and shall be adjusted to include in a lump sum, as soon
as practicable after such death interest credited thereto during the Deferral
Period. Notwithstanding the foregoing, a Participant may elect upon his or her
retirement, in lieu of receiving a distribution from the Plan, to transfer all
or any part of his or her plan benefit to the Wyeth Deferred Compensation Plan
on the terms and conditions set forth therein, in accordance with the election
procedures set forth in that plan.

immediate survivors benefit under this Plan equal to one-half of the Plan
Benefit the Participant would be entitled to receive commencing on the date of
his/her death, assuming the Participant had lived and retired on the day prior
to his death with a 50% Contingent Annuity Option in effect.

         (b) Death of Participant Prior to Attaining Early Retirement Age. Upon
the death of a Participant while employed by the Company prior to having reached

         (c) Death of Participant After a Separation of Service but Before
Commencement of Early Retirement or Vested Plan Benefits. If a Participant has a
Separation from Service while vested and dies prior to attaining his/her Early
Retirement Age or commencing a Vested Plan Benefit, the Participant's Surviving
Spouse shall be entitled to a survivor's annuity commencing on the later of the
Participant's death or the date the Participant would have attained age 55. The
amount of such an annuity shall be equal to one-half of the Early Retirement
Benefit or the Vested Plan Benefit the Participant was entitled to receive as of
the date of his/her Separation from Service commencing as of the date described
above assuming the Participant had elected a 50% Contingent Annuity option.

                     SECTION SEVEN-AMENDMENT AND TERMINATION

or terminate the Plan at any time for any reason. Any such amendment,
modification or termination shall be made pursuant to a resolution of the Board
of Directors and shall be effective as of the date specified in the resolution.
However, no such amendment, modification or termination of the Plan shall
directly or indirectly deprive or adversely affect a Participant's Plan Benefit
under the Plan as in effect on the date immediately preceding the date of such
amendment, modification or termination.

7.2. Termination Benefit. In the event of a Plan termination, each Participant
shall become fully vested in his/her accrued Plan Benefit as of the termination
date. Such accrued Plan Benefit shall be calculated as set forth in Section
4.1(b) above, and shall be based upon the Participant's Years of Service, Final
Average Pension Earnings, and Retirement Plan benefit as of the termination
date. For purposes of determining a Participant's accrued Plan Benefit pursuant
to this paragraph, the Participant's Retirement Plan benefit shall be his/her
accrued benefit from the Retirement Plan payable at age sixty (60). Payment of a
Participant's accrued Plan Benefit shall not be contingent upon his/her
continuation of employment with the Company following the Plan termination date,

Plan Benefit pursuant to of Section Five.

                           SECTION EIGHT-MISCELLANEOUS

limit the right of the Company to discharge or otherwise deal with any
Participant without regard to the existence of the Plan.

8.2. Funding. The Plan at all times shall be entirely unfunded, and no provision

creditor of the Company with respect to any rights under the Plan.
Notwithstanding the foregoing, the Retirement Committee or the Board of
Directors, in their discretion, may segregate the assets in a separate trust
(treated for tax purposes as a Rabbi trust), for the payment of Plan Benefits
and such segregation shall not be regarded as funding the Plan.

8.3. Anti-assignment. To the maximum extent permitted by law, no benefit payable
under the Plan shall be subject in any manner to anticipation, alienation, sale,
transfer, assignment, pledge, attachment, encumbrance, or charge prior to actual

transfer, assign, pledge, attach, encumber, or charge prior to such receipt

full discretionary authority to construe and interpret the Plan, including the
right to remedy possible ambiguities, to adopt, amend, and rescind rules and

the laws of the State of New York, to the extent that such laws are not
preempted by ERISA and the regulations promulgated thereunder.

8.6. Incapacity of Recipient. In the event a Participant, or Surviving Spouse is
declared incompetent and a conservator or other person legally charged with the
care of his/her person or his/her estate is appointed, any benefits under the
Plan to which such Participant, or Surviving Spouse is entitled shall be paid to
such conservator or other person legally charged with the care of his/her person
or estate.

                          SECTION NINE-CLAIMS PROCEDURE

         (c)      set forth any issues or comments which the Participant deems
                  pertinent to the appeal.

The Administrator shall act upon each appeal within 60 days after receipt
thereof unless special circumstances require an extension of the time for
processing, in which case a decision shall be rendered by the Administrator as
soon as possible but not later than 120 days after the appeal is received by it.
The Administrator may require the Participant to submit such additional facts,
documents or other evidence as the Administrator in its discretion deems
necessary or advisable in making its review. The Participant shall be given the
opportunity to review pertinent documents or materials upon submission of a
written request to the Administrator, provided the Administrator finds the
requested documents or materials are pertinent to the appeal.

On the basis of its review, the Administrator shall make an independent
determination of the Participant's eligibility for benefits under the Plan. The
decision of the Administrator on any appeal of a claim for benefits shall be
final and conclusive upon all parties thereto.

In the event the Administrator denies an appeal in whole or in part, it shall
give written notice of the decision to the Participant, which notice shall set
forth, in a manner calculated to be understood by the Participant, the specific
reasons for such denial and which shall make specific reference to the pertinent
provisions of the Plan on which the Administrator's decision is based.
