WARNER-LAMBERT SAVINGS AND STOCK PLAN
FOR COLLEAGUES IN PUERTO RICO

INDEX

INDEPENDENT AUDITORS' REPORT

To the Investment Committee
Warner-Lambert Savings and Stock Plan
for Colleagues in Puerto Rico:

We have audited the accompanying statements of net assets available for plan benefits of the Warner-Lambert Savings and Stock Plan for Colleagues in Puerto Rico (the Plan) as of December 31, 2002 and 2001, and the related statements of changes in net assets available for plan benefits for the years then ended. 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 audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform an 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. 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 available for plan benefits as of December 31, 2002 and 2001, and the changes in net assets available for plan benefits for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule H, line 4i - 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. The supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audits 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.

WARNER-LAMBERT SAVINGS AND STOCK PLAN
FOR COLLEAGUES IN PUERTO RICO
NOTES TO FINANCIAL STATEMENTS
December 31, 2002 and 2001

Note 1 --Description of the Plan

            General -- On June 19, 2000, Pfizer Inc. (the Company) completed a merger with Warner-Lambert Company. In connection with the merger, the Company adopted and assumed the Warner-Lambert Savings and Stock Plan for Colleagues in Puerto Rico (the Plan).  The Plan is a defined contribution profit-sharing savings plan covering employees of the legacy Warner-Lambert Company in Puerto Rico who meet certain eligibility and participation requirements. Those employees who continue to contribute to the Plan are now active employees of the Company.  The following brief description of the Plan is provided for general information purposes only. Participants should refer to the Plan document for more complete information.

            Contributions -- Each Participant may make contributions on a before-tax (that is, choose to reduce his or her compensation and have the Company contribute such amount to the Plan on his or her behalf) and/or an after-tax basis. The Company contributes for each participant an amount equal to 35% and 25% of such participant's before-tax and after-tax contributions, respectively, limited to those participant contributions that are less than or equal to 6% of the participant's base earnings. Based upon the participation and vesting requirements of the Plan, additional lump-sum matching contributions may be made each year of up to 65% of each participant's contributions, up to 6% of base earnings, based upon growth in the Company's earnings-per-common share versus the prior year. Participants who are eligible employees may rollover contributions from other qualified plans into the Plan.

            Investment Options --

            Changes in the participants' allocations relating to their future contributions and their current account balances can be requested at any time. A participant may also suspend contributions or withdraw from the Plan at any time, subject to certain restrictions and penalties.

            The trustee of the Plan, T. Rowe Price (the Trustee), manages investments in its sponsored funds and therefore, is deemed a related party.

            Vesting --Effective January 1, 2002, matching contributions made to participant's accounts on and after that date will become 100% vested upon the completion of three years of service. Matching contributions made to participants' accounts prior to January 1, 2002 will become 100% vested upon the completion of three years of Plan membership or five years of service. Forfeitures reduce contributions otherwise due from the Company. Forfeitures for the plan years 2002 and 2001 were $40 thousand and $19 thousand, respectively.

            Loans to Participants  -- Loans may not exceed the lesser of (1) fifty thousand dollars or (2) 50% of the participant's vested account balance reduced by any current outstanding loan balance. Each loan must be for a minimum of one thousand dollars. All loans will be repaid with interest at a rate that is equal to the prime rate effective as of the last business day of the month before the month in which the loan is taken. Such rate remains in effect for the life of the loan. The term of the loan shall not exceed 60 months. A participant may take only one loan per year and only two loans will be permitted to be outstanding at any time. Participants may only borrow from their vested account balances. Participant loans are presented at cost, which approximates fair value since such loans are subject to variable interest rates.

            Benefit Payments -- Upon retirement, total disability or death, participants or their beneficiaries may elect to have account balances paid as a lump sum payment or in annual installments, or they can purchase an annuity contract. If employment is terminated for any other reason, participants can elect to have a lump-sum payment of the participant account balances in the Company Stock Fund, if vested, and all other savings investment funds.

            Plan Termination -- In the event of termination of the Plan, or if there is a complete discontinuance of contributions under the Plan, all rights of affected participants in accumulated investments credited to them become fully vested. If the Plan is terminated by resolution of the Company's Board of Directors, each participant shall be entitled to the vested balance in accumulated investments credited to his/her account under the Plan.

Note 2 -- Summary of Significant Accounting Policies

            Basis of Accounting -- The financial statements of the Plan are prepared on the accrual basis of accounting.

            Use of Estimates -- The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the plan administrator to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, and the reported amounts of increases and decreases to net assets during the reporting period.  Actual results could differ from those estimates.

            Master Trust Arrangement -- The assets of the Plan have been commingled with the assets of the Warner-Lambert Savings and Stock Plan (collectively referred to as the Plans) in the Warner-Lambert Master Trust (the Master Trust) for investment and administrative purposes. The Plans do not own specific Master Trust assets but rather maintain an undivided beneficial interest in such assets. Each plan's interest in the Master Trust is credited or charged for contributions, transfers and distributions. Investment income is allocated to the Plans based upon each plan's beneficial interest in the net assets of the Master Trust.

            The value of the Fixed Income fund is determined by multiplying $1.00 by the number of shares owned by the Master Trust in the fund.  Within the Fixed Income fund are fully benefit-responsive guaranteed investment contracts, the principal and interest of which are guaranteed. These contracts are valued at contract value representing contributions made under the contracts, plus interest at the contract rate, less funds withdrawn. Contract value approximates fair value. The average annual yield and average annual crediting interest rate of the fully benefit-responsive guaranteed investment contracts for the year ended December 31, 2001 was 6.58%. During 2002, this fund was closed and all assets were redistributed, at the participants' discretion, to other remaining funds. The Equity Index Trust fund is stated at net asset value as determined based on the closing market prices of the underlying investments held. The Stable Value fund's investment contracts, including synthetic investment contracts, are reported at their estimated fair value. The investment contracts are nontransferable, but provide for benefit-responsive withdrawals by plan participants at contract value. Benefit-responsive withdrawals are provided for on a proportional basis by the issuers of the investment contracts. In determining fair value, the fund primarily considers factors such as the benefit responsiveness of the investment contract and the ability of the parties to the investment contract to perform in accordance with the terms of the contract. Generally, fair value approximates contract value (contributions made plus interest accrued at the contract rate, less withdrawals and fees). The investments of the Master Trust that are traded on a national exchange are valued based upon the last published quotations for the last business day of the year.

            Dividend and interest income are recorded by the Trustee as earned by the Master Trust. Net appreciation/ (depreciation) in fair value of Master Trust investments consists of realized and unrealized gains and losses.

            Loan Fund  -- The Loan fund maintains participant loan activity. Interest earned on participant loans is not included in this fund.

            Interest Income from Loans to Participants  -- Interest income from participant loans is recorded by the Trustee as earned in the nonparticipant and participant directed funds in the same proportion as the original loan issuance.

            Expenses -- All expenses are paid by the Plan unless paid by the Company.

Note 3 -- Tax Status of the Plan

            The Bureau of Income Tax of the Department of the Treasury of the Commonwealth of Puerto Rico has ruled that the Plan qualifies under section 165(a) of the Puerto Rico Internal Revenue Code of 1994 (PRIRC) and is, therefore, not subject to tax under present income tax law.  Further, the Plan has received a determination letter advising that the original plan and subsequent amendments through January 1, 1997 are qualified under Section 165(a) of the PRIRC and will be treated for purposes of Section 501(a) of the U.S. Internal Revenue Code (the Code) as an organization described in Section 401(a) of the Code by reason of Section 1022(i)(1) of the Employee Retirement Income Security Act of 1974 (ERISA), as amended.  The Company believes that the Plan is designed and is currently being operated in material compliance with the applicable requirements of the Code and the PRIRC. Accordingly, no provision has been made for federal income taxes.

Note 4 -- Plan Administration

            The Investment Committee (the Committee) of the Plan monitors and reports on the selection and termination of the trustee and investment managers and on the investment activity and performance. The Committee is responsible for the daily administration of the Plan and the Master Trust, including oversight of the investments, the trustee and investment managers.

Note 5 -- Master Trust Financial Information

            The investments of the Master Trust as of December 31, 2002 and 2001 were as follows:

 The investment activity of the Master Trust for the years ended December 31, 2002 and 2001 was as follows:

            Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is possible that changes in their values could occur in the near term and such changes could materially affect the amounts reported in the investments and investment activity of the Master Trust.

            At December 31, 2002 and 2001, the Plan's interest in the Master Trust was approximately 44% and 2%, respectively. The increase in the Plan's interest in the Master Trust results from the transfer out of approximately $1,813 million of assets allocated to the other plan within the Master Trust (see Exhibit I, Note 6 - Transfer Out of Master Trust). The unaudited financial statements of the Master Trust as of and for the years ended October 31, 2002 and 2001 are prepared on the modified cash basis of accounting and are included as Exhibit I to the Plan's Form 11-K.

Note 6 -- Transfer into Plan

            During 2002, the assets for certain participants of another company plan, Agouron Pharmaceuticals, Inc. 401(k) plan, became part of the Plan. As a result, certain participants in this plan became eligible to participate in the Plan and assets of $116 thousand were transferred into the Master Trust.

Note 7 -- Related Party Transactions

            The Master Trust has investments which are managed by the Trustee, therefore, all transactions between the Master Trust and the Trustee qualify as party-in-interest transactions.

Note 8 -- Subsequent Event

            Effective in April 2003, the Plan was merged into the Pfizer Savings and Investment Plan for Employees Resident in Puerto Rico, another Company plan, to form a new plan, The Pfizer Savings Plan for Employees Resident in Puerto Rico.
