INDEPENDENT AUDITORS' REPORT



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



We have audited the accompanying statement 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, 2000, and the related statement of
changes in net assets available for plan benefits for the year 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 audit. The
financial statements of the Plan as of and for the year ended December 31, 1999, were audited by other auditors whose report dated June 6, 2000, expressed an unqualified opinion on those statements.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards 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. 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 audit provides a reasonable basis for our opinion.

In our opinion, the 2000 financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Plan as of December 31, 2000, and its changes in net assets available for
plan benefits for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

Our audit was performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes as of December 31, 2000 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 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.

WARNER-LAMBERT SAVINGS AND STOCK PLAN
FOR COLLEAGUES IN PUERTO RICO
NOTES TO FINANCIAL STATEMENTS
December 31, 2000 and 1999

Note 1 - Summary Plan Description

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 agreement for more complete information.

Contributions -  Participants may elect to contribute into the Plan from a minimum of 1% up to a maximum of 15% of their base earnings each year. Participants have the option of contributing on a before-tax and/or an
after-tax basis. The Company contributes for each participant an amount equal to 35% and 25% of such participant's pre-tax and after-tax contributions, respectively, limited to those participant contributions 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 such participants' contributions, up to 6% of base earnings, based upon growth in the
Company's earnings-per-share versus the prior year. Company contributions are invested in the Company Stock Fund.

Investment Options -



|Company Stock Fund - This fund invests employer contributions in common stock of the Company. Beginning at age 55, participants, if they are vested, can transfer assets at
graduated percentages based on age out of the Company Stock Fund into other investment funds. At December 31, 1999, the Company Stock Fund held shares of legacy Warner-Lambert Company.
|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|Participant Directed Funds- Participants are able to invest in the following six investment  funds:                                                                                                                                                                                                                                                                 
|Colleague Stock Fund -This fund invests in common stock of the Company, to provide an additional opportunity to participate in the performance of the Company's common stock. At
December 31, 1999, the Colleague Stock Fund held shares of legacy Warner-Lambert Company.                                                                                          
|Equity Index Trust* - This fund invests in substantially all common stocks that make up the S&P 500 to match, as closely as possible, the performance of the S&P 500
Composite Stock Index.                                                                                                                                                                         
|Fixed Income Fund* - This fund invests in marketable fixed income securities, as well as a diversified mix of guaranteed investment contracts, bank investment contracts, structured
investment contracts, and separate account contracts issued by high-quality companies, to provide stability of principal value, minimal credit risk and current income.        
|Small-Cap Value Fund* - This fund invests in stocks of small U.S. companies believed to be undervalued at the time of purchase and have potential for capital growth, to provide long-term
capital growth.                                                                                                                                                          
|International Stock Fund* - This fund invests primarily in stocks of established growth companies outside the U.S., predominately in Europe, East Asia, Australia and Canada, as well as
other areas, to provide the diversification of an international fund, as well as the opportunity for long-term capital growth.                                             
|Balanced Fund* - This fund invests in a balanced mix of approximately 60% stocks and 40% bonds, to provide long-term growth of capital and current income.
* T. Rowe Price sponsored fund.                                                                                                                                                                          

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

Changes in the participants' allocations relating to their contributions and the allocation of past contributions and earnings 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.

Vesting -Generally, participating employees become fully vested in Company contributions made on their behalf to the Plan after completing three years of Plan membership or five years of service. Forfeitures reduce
contributions otherwise due from the Company. Forfeitures for the plan years 2000 and 1999 were $23 thousand and $7 thousand, respectively.

Participant Loans -Loans may not exceed the lesser of (1) fifty thousand dollars or (2) 50% of the participant's before-tax 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
48 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 borrow from both the participant's contributions before-tax account balance and the vested matching
contributions account balance in the Company Stock Fund. Participant loans are presented at cost, which approximates fair value.

Benefit Payments - Upon retirement, total disability or death, participants 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 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 participants in accumulated investments credited to them become fully
vested. If the Plan is terminated by resolution of the Company's Board of Directors, the balance in accumulated investments credited to each participant shall be distributed to the participant.



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 management 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), for investment and administrative purposes in the
Warner-Lambert Master Trust (the Master Trust). 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.

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. Short-term investments of the Master Trust are valued at cost, which approximates
fair value. The fully benefit-responsive group annuity and investment contracts, the principal and interest of which are guaranteed, of the Master Trust 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 group annuity and investment contracts for the years ended 12/31/00 and
12/31/99 were 6.45% and 6%, respectively.

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

Expenses -All significant expenses incurred are borne by the Plan.

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 Income Tax Act of 1954 (the Act) and is, therefore, not
subject to tax under present income tax law.  The Plan, being exempt under Section 165 (a) of the Act is subject to the provision of Section 404, which requires the trust to file an annual return stating income, receipts, disbursements, and other
pertinent information.  Further, the Plan has received a determination letter advising that the original plan and subsequent amendments through October 1, 1993 are qualified under Section 165(a) of the Act, as amended, and will be treated for purposes of
Section 501(a) of the 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 compliance with the applicable requirements of the Code.  Accordingly, no provision has been made for federal income taxes.



Note 4 - Plan Administration

The Investment Committee (the Committee) 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, trustee and investment managers.

Note 5 - Interest in Investment Income from the Master Trust

The Plan's interest in investment income from the Warner-Lambert Master Trust was as follows:

EXHIBIT I

WARNER-LAMBERT MASTER TRUST
NOTES TO FINANCIAL STATEMENTS
(thousands of dollars)

(unaudited)

Note 1 - Summary of Significant Accounting Policies

Basis of Accounting - The financial statements of the Warner-Lambert Master Trust (the Master Trust) include the assets of the Warner-Lambert Savings and Stock Plan and the Warner-Lambert Savings and Stock Plan for Colleagues in Puerto
Rico (collectively referred to as the Plans) and are prepared on the cash basis of accounting. The Plans are defined contribution profit-sharing savings plans, subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA), as
amended.

The assets of the Plans have been commingled for investment and administrative purposes in the Master Trust. Accordingly, 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.

Valuation of Investments - Investments traded on a national exchange are valued based upon the last published quotations for the last business day of the year. Short-term investments are valued at cost, which approximates fair value. The
fully benefit-responsive group annuity and investment contracts, the principal and interest of which are guaranteed, 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 group annuity and investment contracts for the years ended 12/31/00 and 12/31/99 were 6.45% and 6%,
respectively.

Investment Income -Dividend and interest income are recorded by T. Rowe Price (the Trustee) as earned. Net appreciation on fair value of investments consists of realized and unrealized gains and losses.

Expenses -All significant expenses incurred are borne by the Plans.

Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management 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.

Risk and Uncertainties -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 and the level of uncertainty related to
changes in the value of investment securities, it is at least reasonably possible that changes in the risks in the near term would materially affect the amounts reported in the Statement of Net Assets Available for Benefits and the Statement of Changes in
Net Assets Available for Benefits.

Note 2 - Tax Status of the Master Trust

The Plans in the Master Trust are intended to be qualified plans under Section 401(a) of the Internal Revenue Code (the Code), and the Master Trust established thereunder is entitled to exemption from federal income tax under the
provisions of section 501(a) of the Code. Accordingly, no provision for federal income taxes has been made.



Note 3 - Significant Investments

The following investments represent over 5% of the assets held for investment purposes by the Master Trust:

In our opinion, the accompanying statements of net assets available for benefits with fund information and the related statements of changes in net assets available for benefits with fund information present fairly, in all material respects, the net
assets available for benefits of the Warner-Lambert Savings and Stock Plan for Colleagues in Puerto Rico (the "Plan") at December 31, 1999 and 1998, and the changes in net assets available for benefits for the years then ended, in conformity with
accounting principles generally accepted in the United States. 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 of these statements in accordance with auditing standards generally accepted in the United States 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 audits provide a reasonable basis for the opinion expressed above.  We have not audited the statements of net assets available for benefits and the related statements of changes in net assets available
for benefits of the Warner-Lambert Savings and Stock Plan for Colleagues in Puerto Rico for any period subsequent to December 31, 1999.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule of Assets Held for Investment Purposes is presented for purposes 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 Fund Information in the statements of net assets available for benefits with fund information and the statements of changes in net assets available for benefits with fund information is presented for purposes
of additional analysis rather than to present the net assets available for benefits and changes in net assets available for benefits of each fund. The Schedule of Assets Held for Investment Purposes and the Fund Information have been subjected to the
auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.
