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


To the Participants and Administrator of
American Home Products Corporation Savings Plan - Puerto Rico:

In our opinion, the accompanying statement of net assets available for plan
benefits and the related statement of changes in net assets available for plan
benefits present fairly, in all material respects, the net assets available for
benefits of American Home Products Corporation Savings Plan - Puerto Rico (the
"Plan") at December 31, 2001, and the changes in net assets available for
benefits for the year then ended in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the Plan's management; our responsibility is to
express an opinion on these financial statements based on our audit. We
conducted our audit of these statements in accordance with auditing standards
generally accepted in the United States of America, which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

Our audit was conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental Schedule of Assets (Held
at End of Year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements but is supplementary information
required by the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. This
supplemental schedule is the responsibility of the Plan's management. The
supplemental schedule has been subjected to the auditing procedures applied in
the audit of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

We conducted our audits in accordance with auditing standards generally accepted

supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets applicable to participants' equity of the

2000 and 1999, and the changes in its net assets applicable to participants'
equity for the year ended December 31, 2000, in conformity with accounting

Our audits were performed for the purpose of forming an opinion on the basic

                       AMERICAN HOME PRODUCTS CORPORATION
                           SAVINGS PLAN - PUERTO RICO
                          NOTES TO FINANCIAL STATEMENTS




NOTE 1 - PLAN DESCRIPTION
         ----------------

The following description of the American Home Products Corporation Savings Plan
- - Puerto Rico (the "Plan") only provides general information. Participants of
the Plan should refer to the Plan Document for a more detailed and complete
description of the Plan's provisions.

General
- -------

The Plan, a defined profit sharing contribution plan, was approved and adopted
by the Board of Directors of American Home Products Corporation ("AHPC" or the
"Company") and became effective on January 1, 1993. Effective March 11, 2002 the
Company changed its name to Wyeth. Full-time employees of the Company and its
participating subsidiaries who reside in Puerto Rico and are not subject to a
collective bargaining agreement ("non-union") are eligible to participate in the
Plan after attaining age 21, as defined in the Plan. Part-time employees
additionally must complete at least 1,000 hours during the first 12 months of
employment or during any calendar year following the year in which they are
hired. The Plan is subject to the provisions of the Employee Retirement Income
Security Act of 1974 ("ERISA"), as amended, and the Puerto Rico Internal Revenue
Code (the "PR Code").

Contributions
- -------------

Participants may elect to make contributions to the Plan in whole percentages up
to a maximum of 16% of their covered compensation, as defined. Contributions can
be made on a before-tax basis ("salary deferral contributions"), an after-tax
basis ("after-tax contributions"), or a combination of both. The Company will
contribute an amount equal to 50% of the participant's contributions to the Plan
for contributions up to 6% of the participant's covered compensation.
Participants direct the investment of their contributions and Company
contributions into various investment options offered by the Plan. Under the PR
Code, total annual salary deferral contributions that can be included for Plan
purposes are subject to annual limitations.

Vesting and Separation From Service
- -----------------------------------

Participants are fully vested at all times in their salary deferral and
after-tax contributions plus actual earnings thereon. A participant is also
fully vested in Company matching contributions if the participant has at least
five years of continuous service, as defined. If participants have less than
five years of continuous service, such participants become vested in their
Company matching contributions according to the following schedule:

                                      - 3 -







                                                      Vesting
               Years of Continuous Service           Percentage
               ---------------------------           ----------
                    1 year completed                      0%
                    2 years completed                    25%
                    3 years completed                    50%
                    4 years completed                    75%
                    5 years completed                   100%

Regardless of the number of years of continuous service, participants shall be
fully vested in their Company matching contributions account upon reaching age
65 or upon death, if earlier. If employment is terminated prior to full vesting,
the non-vested portion of the Company matching contributions is forfeited and
becomes available to satisfy future Company matching contributions. During 2001,
forfeitures of $61,019 were used to offset Company matching contributions. As of
December 31, 2001 and 2000, the amount of forfeitures available to offset future
Company matching contributions totaled $9,459 and $14,565, respectively.

Distributions
- -------------

Participants are entitled to withdraw all or any portion of their after-tax
contributions. Participants may make full or partial withdrawals of funds in any
of their accounts upon attaining age 59 1/2 or for financial hardship, as
defined in the Plan Document, before that age. Participants may qualify for
hardship withdrawals if they have an immediate and heavy financial need, as
determined by the AHPC Savings Plan Committee - Puerto Rico (the "Committee").
Participants are limited to one non-hardship and one hardship withdrawal each
year. Participants may make hardship withdrawals provided they have no other
funds that are readily available to meet that need.

Upon termination of employment, participants are entitled to a lump-sum
distribution of their vested account balance. Participants can defer the
distribution of their account if the participant's account balance is greater
than $5,000 and if the participant is less than 70 1/2 years of age.

Loans
- -----

Participants who have a vested account balance of at least $2,000 may borrow
from the vested portion of their account, subject to certain maximum amounts.
Participants in the Plan may borrow up to 50% of their vested account balances.
Each loan is secured by the borrower's vested interest in their account balance.
Participants may have outstanding up to two general purpose loans and one loan
to acquire or construct a principal residence. All loans must be repaid within 5
years except for those used to acquire or construct a principal residence, which
must be repaid within 15 years. Defaults on participants' loans during the year
are treated as withdrawals and are fully taxable to the participants. The
interest rate charged on loans provides a return commensurate with a market
rate, or such other rate as permitted by government regulations as of the date
of the loan agreement.

NOTE 2 - ACCOUNTING POLICIES
         -------------------

Basis of Accounting
- -------------------

The accompanying financial statements are prepared on the accrual basis of
accounting.

Contributions
- -------------

Contributions from the employer are accrued based upon amounts required to be
funded under the provisions of the Plan. Contributions from employees are
accrued when deducted from payroll.

Benefits
- --------

Benefits are recorded when paid.

Investment Valuation
- --------------------

The AHPC Common Stock Fund is recorded at fair market value. Shares in the
Fidelity Funds and the MSIF Trust Value Portfolio are recorded at fair market
value, which is based on their published net asset value. The investment
contracts comprising the Interest Income Fund are recorded at contract value
based upon information provided by Fidelity Management Trust Company which
approximates fair market value (see also NOTE 3).

Investment transactions are recorded on a trade date basis.

Administrative Costs
- --------------------

All costs and expenses of administering the Plan are paid by the Company.

Risks and Uncertainties
- -----------------------

The Plan's assets consist of various investments which are exposed to various
risks, such as interest rate, market and credit. Due to the level of risk
associated with certain investment securities and the level of uncertainty
related to changes in the value of investment securities, it is at least
reasonably possible that changes in risks in the near term would materially
affect participants' account balances and the amounts reported in the statements
of net assets available for plan benefits and the statement of changes in net
assets available for plan benefits.

Use of Estimates
- ----------------

The financial statements have been prepared in accordance with accounting
principles generally accepted in the United States and necessarily include
amounts based on judgements and estimates made by management. Actual results

NOTE 3 - INVESTMENT ELECTIONS
         --------------------

Participants can elect to invest amounts credited to their account in any of
eight investment funds offered by the Plan and transfer amounts between these
funds at any time during the year. Investment elections must be made in
multiples of 10%. Transfers between funds must be made in whole percentages
and/or in an amount of at least $250.

The eight investment options are as follows for 2001 and 2000:

    Interest Income Fund - consists primarily of investment contracts issued by
    life insurance companies which pay a specified rate of interest for a fixed
    period of time and repay principal at maturity. The fund and its investment
    contracts are guaranteed by the issuing insurance carrier, but not by the
    Company or any federal agency. However, the Committee has established
    guidelines that provide that investment contracts be placed with companies
    rated Aa3 or higher by Moody's and AA- or higher by Standard & Poor's. The
    interest rate payable to Plan participants in this fund will be a rate which
    reflects a blend of the total investments made by the fund. The average
    blended interest rate attributable to these contracts approximated 6.24% and
    6.53% for 2001 and 2000, respectively.

    AHPC Common Stock Fund - consists primarily of Company common stock.
    Purchases and sales of AHPC common stock are made in the open market.
    Participants have full voting rights for equivalent shares purchased at
    their direction under the Plan.

    Fidelity Magellan Fund - consists of shares in a mutual fund managed by
    Fidelity Management & Research Company that seeks long-term capital
    appreciation by actively managing investments in the stocks of companies
    that the investment manager believes possess above average growth potential.

    Fidelity Balanced Fund - consists of shares in a mutual fund managed by
    Fidelity Management & Research Company, which is invested in high yielding
    securities, including common stocks, preferred stocks and bonds, with at
    least 25% of the fund's assets in fixed income senior securities.

    Fidelity International Growth & Income Fund - consists of shares in a mutual
    fund managed by Fidelity Management & Research Company that seeks long-term
    growth and current income by investing in assets, of which at least 65% are
    in securities of issuers that have their principal business activities
    outside of the United States.

    Fidelity Spartan U.S. Equity Index Fund - consists of shares in a mutual
    fund managed by Fidelity Management & Research Company that seeks to provide
    investment results that correspond to the total return performance of the
    stocks of companies that make up the Standard & Poor's 500 Index.

    Fidelity Low-Priced Stock Fund - consists of shares in a mutual fund managed
    by Fidelity Management & Research Company that invests primarily in domestic
    and international small capitalization equities.

                                      - 6 -







    MSIF Trust Value Portfolio - consists of shares in a mutual fund managed by
    Morgan Stanley which seeks long-term returns by investing in stocks of large
    and mid-sized companies.

NOTE 4 - MANAGEMENT OF THE PLAN
         ----------------------

The Plan is administered by the Committee, which was appointed by the Board of
Directors of the Company. Banco Popular de Puerto Rico is the Plan's trustee.
Fidelity Management Trust Company was appointed by the Committee as recordkeeper
and custodian, and is a party-in-interest to the Plan.

NOTE 5 - PLAN AMENDMENTS
         ----------------

The Plan was amended in 2001 for certain regulatory requirements and
administrative enhancements.

NOTE 6 - INCOME TAX STATUS
         -----------------

Puerto Rico
- -----------

The Plan is designed to be a qualified profit-sharing plan under Section 165(a)
of the Puerto Rico Income Tax Act of 1954 (the "Act") and the trust established
under the Plan is intended to be tax-exempt under Section 165(a) of the Act. The
Company has obtained from the Puerto Rico Treasury Department a favorable
determination letter that covers all plan amendments through January 1, 1996.
The Plan has been amended since receiving the determination letter. However, the
Plan administrator believes that the Plan and the trust meet the requirements of
the Act.

Federal Income Tax Status
- -------------------------

The Plan does not constitute a qualified profit-sharing plan under the
provisions of Section 401(a) of the Internal Revenue Code (the "Code") and the
"cash and deferred arrangement" incorporated in the Plan is not intended to
qualify under Section 401(k) of the Code. Pursuant to Section 1022(i)(1) of
ERISA, however, the trust established thereunder is exempt from Federal income
tax under Section 501(a) of the Code. An individual who is a bona fide resident
of Puerto Rico during the entire taxable year will not be subject to any Federal
income tax on income derived from sources within Puerto Rico.

NOTE 7 - PLAN TERMINATION
         ----------------

Although it has not expressed any intention to do so, the Company has the right
under the Plan to discontinue its contributions at any time and to terminate the
Plan subject to the provisions of ERISA. In the event of Plan termination,
participants will become 100% vested in their Company contribution amounts and
are entitled to full distribution of such amounts.
