PFIZER INC. AND SUBSIDIARY COMPANIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)



Note 1:  Basis of Presentation

We prepared the condensed consolidated financial statements following the requirements of the Securities and Exchange Commission (SEC) for interim reporting.  As permitted under those rules, certain footnotes or other financial information that are
normally required by GAAP (generally accepted accounting principles) can be condensed or omitted. Balance sheet amounts and operating results for subsidiaries operating outside the U.S. are as of and for the three-month periods ending February 25,
2001 and February 27, 2000. We made certain reclassifications to the 2000 condensed consolidated financial statements to conform to the 2001 presentation.

Note 2:  Responsibility for Interim Financial Statements

We are responsible for the unaudited financial statements included in this document.  The financial statements include all normal and recurring adjustments that are considered necessary for the fair presentation of our financial position and operating
results.  As these are condensed financial statements, one should also read the financial statements and notes included in our company's latest Form 10-K.

Revenues, expenses, assets and liabilities can vary during each quarter of the year.  Therefore, the results and trends in these interim financial statements may not be the same as those for the full year.

Note 3: Adoption of New Accounting Standards

Accounting for Certain Sales Incentives

On January 1, 2001, we adopted the provisions of the Emerging Issues Task Force Issue No. 00-14,Accounting for Certain Sales Incentives, which address the income statement classification of certain sales incentives.  As a result, we
reclassified the cost of certain sales incentives from Selling, informational and administrative expenses to Revenues.  We restated the prior period to reflect the current year presentation. These reclassifications have no effect on net income.

Derivative Financial Instruments and Hedging Activities

On January 1, 2001, we adopted the provisions of Statement of Financial Accounting Standards (SFAS) No. 138,



The following disclosures relate to derivative and hedging instruments as of April 1, 2001:

Purpose

Foreign Exchange Risk

A significant portion of revenues, earnings and net investments in foreign affiliates are exposed to changes in foreign exchange rates. We seek to manage our foreign exchange risk through operational means, including managing expected local
currency revenues in relation to local currency costs and local currency assets in relation to local currency liabilities. Significant foreign exchange risk is also managed though the use of derivative financial instruments and Japanese yen denominated
debt as follows:

- $3,915 million notional amount of foreign currency forward contracts are used to offset the potential earnings effects from short-term foreign currency assets and liabilities in mostly intercompany cross-border transactions that arise from
operations.  We have entered into such contracts primarily to sell euro, Japanese yen, U.K. pounds and Canadian dollars in exchange for U.S. dollars.

- $1,156 million of short-term Japanese yen debt is designated as a net investment hedge of our yen net investments in operations in order to limit the risk of adverse changes in the value of such investments.

- $438 million notional amount of foreign currency swaps are designated as cash flow hedges of a U.K. pound intercompany loan maturing in 2003 in order to reduce the variability in U.S. dollar cashflows related to the interest payments and the
principal repayment.

- $143 million notional amount of foreign currency swaps are designated as fair value hedges of U.K. pound debt investments maturing through late 2001 in order to reduce the variability in U.S. dollar cash flows related to interest receipts and the
principal repayment.

- $96 million notional amount of foreign currency swaps are designated as fair value hedges of Pfizer International Bank Europe euro loans maturing in late 2001 in order to reduce the variability in U.S. dollar cash flows related to interest receipts
and the principal repayment.



Interest Rate Risk

Our interest-bearing investments, loans and borrowings are subject to interest rate risk. We invest and borrow primarily on a short-term or variable-rate basis. Significant interest rate risk is also managed though the use of derivative financial
instruments as follows:

- $967 million notional amount of yen interest rate swaps maturing in 2003 are designated as cash flow hedges of the yen "LIBOR" interest rate related to forecasted issuances of short-term debt. These swaps serve to reduce the variability of
the yen interest rate by effectively fixing the rates on short-term debt at 1.2%.
- $750 million notional amount of U.S dollar interest rate swaps maturing in 2006 are designated as fair value hedges of the changes in the fair value of fixed-rate debt attributable to changes in the designated benchmark interest rate, "
LIBOR".

Accounting Policies

All derivative contracts are reported at fair value, with changes in fair value reported in earnings or deferred, depending on the nature and effectiveness of the offset or hedging relationship, as follows:

Foreign Exchange Risk

- We recognize the earnings impact of foreign currency forward contracts during the terms of the contracts, along with the earnings impact of the items they generally offset.

- We recognize the earnings impact of foreign currency swaps designated as cash flow or fair value hedges upon the recognition of the foreign exchange gain or loss on the translation to U.S. dollars of the hedged item.

Interest Rate Risk

- We recognize the earnings impact of interest rate swaps designated as cash flow hedges upon the recognition of the interest related to the hedged short-term debt.
- We recognize the earnings impact of interest rate swaps designated as fair value hedges upon the recognition of the change in fair value for interest rate risk related to the hedged long-term debt.

Any ineffectiveness in a hedging relationship is recognized immediately into earnings.

The financial statements include the following items related to the derivatives and other financial instruments serving as hedges or offsets:

Other current liabilities includes:

- fair value of foreign currency forward contracts

- fair value of foreign currency swaps



Other noncurrent liabilities includes:

- fair value of interest rate swaps designated as cash flow and fair value hedges and fair value of foreign currency swaps designated as cash flow hedges

Long-term debt includes:

- changes in the fair value of fixed rate debt hedged by interest rate swaps designated as fair value hedges

Accumulated other comprehensive expense includes changes in the:

- foreign exchange translation of yen debt and foreign currency swaps and interest rate swaps designated as cash flow hedges

Other income - net includes changes in the fair value of:

- foreign exchange forward contracts
- foreign currency swap contracts that hedge foreign exchange

- interest rate swap contracts that hedge interest expense

Through April 1, 2001, the charges for employee termination costs represent the approved reduction of our work force by 5,624 people, mainly comprising administrative functions for corporate, manufacturing, distribution, sales and
research. We notified these people and as of April 1, 2001, 4,940 employees were terminated. We will complete terminations of the remaining personnel within one year of the notification. Employee termination costs include accrued severance benefits
and costs associated with change-in-control provisions of certain Warner-Lambert employment contracts. Under the terms of Warner-Lambert employment contracts, certain terminated employees may elect to defer receipt of severance benefits. The deferred
severance benefits are considered utilized and are included in Other noncurrent liabilitiesas of April 1, 2001 and December 31, 2000.

The impairment and disposal charges through April 1, 2001 for property, plant and equipment represent the consolidation of facilities and related fixed assets, a contract termination payment and termination of certain software installation
projects.  Other restructuring charges in the three months ended April 1, 2001 consist of charges for contract termination payments-$2 million ($18 million since inception of merger) facility closure costs-$1 million ($5 million since inception
of merger) and assets we wrote off, including inventory and intangible assets-$3 million ($8 million since inception of merger).

At April 1, 2001, accrued restructuring charges are included in Other current liabilities.

Stock options and stock issuable under employee compensation plans representing equivalents of 170 million shares of common stock were outstanding during the first quarter of 2000.  These potential common shares were excluded from the
computation of diluted earnings per share in 2000 because their inclusion would have had an antidilutive effect.

INDEPENDENT AUDITORS' REPORT





To the Shareholders and Board of Directors of Pfizer Inc.:

We have reviewed the condensed consolidated balance sheet of Pfizer Inc. and Subsidiary Companies as of April 1, 2001 and the related condensed consolidated statements of operations and cash flows for the three-month periods ended April 1,
2001 and April 2, 2000.  These condensed consolidated financial statements are the responsibility of the Company's management. The condensed consolidated financial statements for 2000 give retroactive effect to the merger on June 19, 2000 of
Pfizer Inc. and Subsidiary Companies and Warner-Lambert Company and its subsidiaries which was accounted for as a pooling of interests.

We conducted our review in accordance with standards established by the American Institute of Certified Public Accountants.  A review of interim financial information consists principally of applying analytical procedures to financial data and making
inquiries of persons responsible for financial and accounting matters.  It is substantially less in scope than an audit conducted in accordance with generally accepted auditing standards, the objective of which is the expression of an opinion regarding
the financial statements taken as a whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the condensed consolidated financial statements referred to above for them to be in conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing standards, the consolidated balance sheet of Pfizer Inc. and Subsidiary Companies as of December 31, 2000, and the related consolidated statements of income, shareholders'
equity and cash flows for the year then ended (not presented herein); and in our report dated February 22, 2001, we expressed an unqualified opinion on those consolidated financial statements.  In our opinion, the information set forth in the
accompanying condensed consolidated balance sheet as of December 31, 2000, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

The revenue increase was due to sales volume growth of our in-line products and revenue generated from product alliances.

The currency impact on the first quarter 2001 revenue growth primarily reflects the weakening of the euro and yen relative to the dollar.

Revenues for the first quarter by segment and the changes over the prior year were as follows:

Alliance revenue reflects revenue associated with the copromotion of:

Celebrex, discovered and developed by our alliance partner Pharmacia Corporation, is used for relief of the pain and inflammation of osteoarthritis and adult rheumatoid arthritis.

Aricept, discovered and developed by our alliance partner Eisai Co., Ltd., is used to treat symptoms of Alzheimer's disease.

Alliance revenue in the U.S. declined in the first quarter of 2001 as compared to the first quarter of 2000 mainly due to trade purchasing of Celebrex last year in advance of a December 2000 price increase by Pharmacia and competitive pressures on
Aricept. Strong international performances of both products led to the 15% increase in worldwide alliance revenue in the first quarter of 2001.

Animal Health sales for the first quarter of 2001 decreased 17% (down 13% excluding the effects of foreign exchange) compared to the same period in 2000. The 17% decline principally reflects the sale of feed-additive product lines in November 2000 and
the adverse impact of foreign exchange. Other factors contributing to the decline in sales include the initial distribution of the anti-parasitic Revolution in the U.S. and various international markets in the prior year and the impact in 2001 of mad-cow
and foot-and-mouth diseases in Europe.

We expect performance of the Animal Health business to improve over the course of 2001 reflective of new promotional and distribution practices and various restructuring initiatives.

Consumer Products

Sales of the Consumer Products segment for the first quarter of 2001 decreased by 4% (down 1% at constant exchange rates) to $1,272 million compared to the same period in 2000. Worldwide sales of the Consumer Products segment follow:

|                              | First Quarter
|----------------------------- | -------------
|(millions of dollars)         | 2001         
|                              |              
|Consumer Health Care Products | $  591       
|Confectionery Products        | 469          
|Shaving Products              | 172          
|Tetra Fish Products           | 40           
|Total Consumer Products       | $1,272
======



Consumer Health Care product sales decreased 2% (remained flat at constant exchange rates) in the quarter to $591 million, mainly due to a mild cough/cold season in Europe and the adverse effect of foreign exchange, offset by strong sales growth
of Sudafed, Benadryl, Lubriderm and Zantac 75. Sales of Confectionery products declined 3% (a 1% decline at constant exchange rates) in the first quarter to $469 million, mainly due to the adverse effect of foreign exchange, competition in
Brazil and Italy and weak economies in Mexico and Argentina, offset in part by a strong performance of Dentyne Ice and Trident in North American markets.

Despite the first quarter decline in sales of the Consumer Products segment, we continue to believe that the measures instituted during the course of 2000-new management and productivity improvements-will result in improved operating performance in
2001 relative to a year ago.  We expect sales performance will further benefit from new product introductions and line extensions.

Revenues by Country

Revenues in the U.S. increased due to growth in pharmaceutical sales as described above. Revenues by country were as follows:

COSTS AND EXPENSES

Cost of Sales

Cost of sales decreased 1% in the first quarter of 2001 over the prior year period, while revenues increased 7%. The decrease in cost of sales is primarily due to favorable product and business mix, integration synergies, manufacturing
efficiencies and the favorable impact of foreign exchange.

Selling, Informational and Administrative Expenses

Selling, informational and administrative expenses decreased 6% in the first quarter of 2001 over the prior year period mainly due to cost savings stemming from the integration of Pfizer and Warner-Lambert and the favorable impact of foreign
exchange.

Research and Development Expenses

Research and development expenses decreased 3% in the first quarter of 2001 over the prior year period due to merger-related synergies and the favorable impact of foreign exchange. Excluding merger-related cost savings and foreign exchange,
research and development expenses increased as we continued to increase support for our broad new-product pipeline. For 2001, we have a total R&D budget of about $5 billion.



In the first quarter of 2001, we filed the following indications with the FDA:

|Product   | Indication                                        | Date Filed

|Zoloft    | Premenstrual dysphoric disorder                   | January 2001 

In the first quarter of 2001, Pharmacia Corporation filed a New Drug Application with the FDA for valdecoxib, for the treatment of osteoarthritis, rheumatoid arthritis and pain. Pharmacia is the discoverer of the product and our partner
on commercialization of the compound.

Additional product-related programs are in various stages of discovery and development.

On April 11, 2001, we announced a worldwide agreement with Boehringer Ingelheim to jointly market Spiriva (tiotropium), which we expect to be the first once-a-day inhaled treatment for chronic obstructive pulmonary disease.  Spiriva was discovered and
developed by Boehringer Ingelheim.  A New Drug Application for Spiriva is anticipated to be filed with the FDA later this year.

MERGER-RELATED COSTS

Through April 1, 2001, the charges for employee termination costs represent the approved reduction of our work force by 5,624 people, mainly comprising administrative functions for corporate, manufacturing, distribution, sales and
research. We notified these people and as of April 1, 2001, 4,940 employees were terminated. We will complete terminations of the remaining personnel within one year of the notification. Employee termination costs include accrued severance benefits
and costs associated with change-in-control provisions of certain Warner-Lambert employment contracts. Under the terms of Warner-Lambert employment contracts, certain terminated employees may elect to defer receipt of severance benefits. The deferred
severance benefits are considered utilized and are included in Other noncurrent liabilitiesas of April 1, 2001 and December 31, 2000.

The impairment and disposal charges through April 1, 2001 for property, plant and equipment represent the consolidation of facilities and related fixed assets, a contract termination payment and termination of certain software installation projects.

Other restructuring charges in the three months ended April 1, 2001 consist of charges for contract termination payments-$2 million ($18 million since inception of merger), facility closure costs-$1 million ($5 million since inception of
merger) and assets we wrote off, including inventory and intangible assets-$3 million ($8 million since inception of merger).

At April 1, 2001, accrued restructuring charges are included in Other current liabilities.

We expect to incur additional restructuring and integration charges in future periods as the integration of Pfizer and Warner-Lambert continues.

In the first quarter of 2001, we achieved integration-related synergies of about $270 million.  We anticipate merger-related cost savings of $1.2 billion in 2001 and at least $1.6 billion in 2002.  Savings to date largely stem from the elimination of
redundant positions in the work force and operating expenses.  Most of the savings to date have been realized from the consolidation of various administrative and support functions around the world and our initial realization of the purchasing
opportunities associated with the activities of the combined entity.

Interest income in the first quarter of 2001 increased over the prior year period as a result of higher average investment levels partially offset by lower average interest rates in the first quarter of 2001. Interest expense in the first
quarter of 2001 decreased over the prior year period as a result of a lower average level of borrowings and lower average interest rates in the first quarter of 2001.

TAXES ON INCOME

Our projected tax rate in 2001, excluding the effect of certain significant items and merger-related costs of 26.2%, is lower than the comparable rate of 27.2% in 2000 due primarily to changes in product mix and tax-planning initiatives.

NET INCOME

Net income and diluted earnings per share, excluding certain significant items and merger-related costs, increased by 34% and 32% in the first quarter of 2001. A reconciliation between reported net income and net income excluding certain
significant items and merger-related costs follows:

* Cash is managed by country or region and is not always available to be used in every location throughout the world. When necessary, we utilize short-term borrowings for various corporate purposes.

** Represents total shareholders' equity divided by the actual number of common shares outstanding (which excludes treasury shares and those held by our employee benefit trusts).

The increase in working capital from December 31, 2000 to April 1, 2001 reflects:

- cash from current period operations
- the issuance in January 2001 of $750 million in long-term debt (the proceeds of which were used to repay certain short-term borrowings)
- increases in accounts receivable and inventories partially offset by

- purchases of property, plant and equipment
- purchases of common stock
- dividends on common stock

The increase in shareholders' equity per common share is primarily due to growth in net income.

Net Cash Provided by Operating Activities

During the first quarter of 2001, net cash provided by operating activities was $1,814 million, as compared to $52 million in the 2000 period.  The change was primarily due to:

- the absence in 2001 of the transaction costs in the first quarter of 2000 of $1,838 million related to Warner-Lambert's termination of the Warner-Lambert/American Home Products merger partially offset by

- an increase in accounts receivable

Net Cash Used in Investing Activities

In the first quarter of 2001, investing activities used net cash of $1,259 million, as compared to $1,081 million in the 2000 period.  The increase in net cash used in investing activities in 2001 was primarily attributable to

- higher purchases of long-term investments and other assets
- less proceeds received from the sales of research-related equity investments and other assets
- absence of proceeds from sale of business

partially offset by

- fewer purchases of short-term investments
- fewer purchases of property, plant and equipment

Net Cash Provided by/Used in Financing Activities

In the first quarter of 2001, net cash used in financing activities was $474 million, as compared to net cash provided by financing activities of $32 million in the 2000 period. This change was primarily attributable to:

- an increase in common share purchases
- an increase in cash dividends paid
- less cash received from employee stock option exercises

partially offset by

- an increase in net proceeds from borrowings

In January 2001, we issued $750 million in senior unsecured notes under a $2.5 billion shelf registration filed with the Securities and Exchange Commission in October 2000. The notes mature on February 1, 2006, with interest
payable semi-annually, beginning on August 1, 2001, at a rate of 5.625%.  The proceeds from the notes were used to repay certain short-term borrowings.

During the first quarter of 2001, we purchased approximately 11.3 million shares of common stock on the open market at an average price of about $42.88 per share.  Through April 1, 2001, we purchased approximately 118 million shares at a total cost of
about $4.6 billion under the current $5 billion share purchase program begun in September 1998.  We are on track to complete the current program during the second quarter of 2001.

INVESTMENT AGREEMENT

In March of 2001, we announced plans to form an independent company along with Microsoft and IBM that will develop software and services for physician practices.  The focus of the company will be to reduce the administrative workload for
physicians, allowing them to put more time toward their mission of providing quality patient care.  The new company is expected to make its first products available to the general market later this year.

FINANCIAL RISK MANAGEMENT

In March 2001, Pfizer purchased $276 million notional amount of Japanese put options to partially hedge the U.S. dollar/Japanese yen exchange impact related to anticipated intercompany inventory purchases through the end of this year.

OUTLOOK

We expect to obtain double-digit reported revenue growth despite the increased negative impact of foreign exchange which based on exchange rates at the end of the first quarter of 2001 would negatively impact revenue growth by more than $700
million. We expect the negative impact of foreign exchange to be felt most heavily in the first half of 2001.  For 2001, diluted earnings per share are projected at $1.27 to $1.30, or 25% to 27% growth, excluding certain significant items and
merger-related costs.  The vast majority of growth in 2001 is expected to come from operations, with merger-related cost savings providing an additional benefit.  For 2002, diluted earnings per share are projected at $1.56 or better, excluding certain
significant items and merger-related costs.

CAUTIONARY FACTORS THAT MAY AFFECT FUTURE RESULTS

Our disclosure and analysis in this report contain forward-looking information about our company's financial results and estimates, business prospects and products in research that involve substantial risks and uncertainties. From time to time, we
also may provide oral or written forward-looking statements in other materials we release to the public.  Forward-looking statements give our current expectations or forecasts of future events. You can identify these statements by the fact that they do
not relate strictly to historic or current facts.  They use words such as "anticipate," "estimate," "expect," "project," "intend," "plan," "believe," and other words and terms of similar meaning in connection with any discussion of future operating or
financial performance.  In particular, these include statements relating to future actions, prospective products or product approvals, future performance or results of current and anticipated products, sales efforts, expenses, the outcome of
contingencies, such as legal proceedings, and financial results.  Among the factors that could cause actual results to differ materially are the following:

- the success of research and development activities and the speed with which regulatory authorizations and product launches may be achieved
- competitive developments affecting our current growth products
- the ability to successfully market both new and existing products domestically and internationally
- difficulties or delays in manufacturing
- trade buying patterns
- ability to meet generic and branded competition after the expiration of our company's patents
- trends toward managed care and health care cost containment
- possible U.S. legislation affecting pharmaceutical pricing and reimbursement or Medicare
- exposure to product liability and other types of lawsuits
- contingencies related to actual or alleged environmental contamination
- our company's ability to protect its intellectual property both domestically or internationally
- interest rate and foreign currency exchange rate fluctuations
- governmental laws and regulations affecting domestic and foreign operations, including tax obligations
- changes in generally accepted accounting principles
- growth in costs and expenses
- changes in our product mix
- the impact of acquisitions, divestitures, restructurings, product withdrawals and other unusual items

We cannot guarantee that any forward-looking statement will be realized, although we believe we have been prudent in our plans and assumptions.  Achievement of future results is subject to risks, uncertainties and inaccurate assumptions.  Should known
or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could vary materially from those anticipated, estimated or projected.  Investors should bear this in mind as they consider forward-looking
statements.

We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise.  You are advised, however, to consult any further disclosures we make on related subjects in our 10-Q, 8-K
and 10-K reports to the Securities and Exchange Commission. Our Form 10-K filing for the 2000 fiscal year listed various important factors that could cause actual results to differ materially from expected and historic results.  We note these factors for
investors as permitted by the Private Securities Litigation Reform Act of 1995.  Readers can find them in Item 1 of that filing under the heading "Cautionary Factors That May Affect Future Results." We incorporate that section of that Form 10-K in
this filing and investors should refer to it.  You should understand that it is not possible to predict or identify all such factors.  Consequently, you should not consider any such list to be a complete set of all potential risks or uncertainties.

On June 9, 1997, the Company received notice of the filing of an Abbreviated New Drug Application (ANDA) by Mylan Pharmaceuticals for a sustained-release nifedipine product asserted to be bioequivalent to Procardia XL. Mylan's notice
asserted that the proposed formulation does not infringe relevant licensed Alza and Bayer patents and thus that approval of their ANDA should be granted before patent expiration. On July 18, 1997, the Company, together with Bayer AG and Bayer Corporation,
filed a patent-infringement suit against Mylan Pharmaceuticals Inc. and Mylan Laboratories Inc. in the U.S. District Court for the Western District of Pennsylvania with respect to Mylan's ANDA. Suit was filed under Bayer AG's U.S. Patent 5,264,446,
licensed to the Company, relating to nifedipine of a specified particle size range. On March 16, 1999, the court granted Mylan's motion to file an amended answer and antitrust counterclaims. On December 17, 1999, Mylan received final approval from the FDA
for its 30 mg. extended-release nifedipine tablet. On February 28, 2000, a settlement agreement was entered into between Mylan and the Company under which the litigation was terminated and Mylan was licensed to market a generic sustained-release
nifedipine product manufactured by the Company under its own trademark.

On or about February 23, 1998, Bayer AG received notice that Biovail Laboratories Incorporated had filed an ANDA for a sustained-release nifedipine product asserted to be bioequivalent to one dosage strength (60 mg.) of Procardia XL. The notice
was subsequently received by the Company as well. The notice asserts that the Biovail product does not infringe Bayer's U.S. Patent 5,264,446. On March 26, 1998, the Company received notice of the filing of an ANDA by Biovail Laboratories of a 30 mg.
dosage formulation of nifedipine alleged to be bioequivalent to Procardia XL. On April 2, 1998, Bayer and Pfizer filed a patent-infringement action against Biovail, relating to their 60 mg. nifedipine product, in the U.S. District Court for the District of Puerto Rico. On May 6, 1998, Bayer and Pfizer filed a
second patent infringement action in Puerto Rico against Biovail under the same patent with respect to Biovail's 30 mg. nifedipine product. These actions have been consolidated for discovery and trial. On April 24, 1998, Biovail Laboratories Inc. brought
suit in the U.S. District Court for the Western District of Pennsylvania against the Company and Bayer seeking a declaratory judgment of invalidity of and/or non-infringement of the 5,264,446 nifedipine patent as well as a finding of violation of the
antitrust laws. Biovail has also moved to transfer the patent infringement actions from Puerto Rico to the Western District of Pennsylvania. Pfizer has opposed this motion to transfer and on June 19, 1998, moved to dismiss Biovail's declaratory judgment
action and antitrust action in the Western District of Pennsylvania, or in the alternative, to stay the action pending the outcome of the infringement actions in Puerto Rico. On January 4, 1999, the court in Pennsylvania granted Pfizer's motion for a stay
of the antitrust action pending the outcome of the infringement actions in Puerto Rico. On January 29, 1999, the court in Puerto Rico denied Biovail's motion to transfer the patent infringement actions from Puerto Rico to the Western District of
Pennsylvania. On April 12, 1999, Biovail filed a motion for summary judgment based in part on the summary judgment motion granted to Elan in the Bayer v. Elan litigation in the Northern District of Georgia. Pfizer and Bayer's response was filed on April
26, 1999. On September 20, 1999, the court in Puerto Rico denied Biovail's motion for summary judgment without prejudice to their refiling after completion of discovery in the Procardia XL patent-infringement litigation. Fact discovery has been completed, but expert discovery continues.

In two decisions in March 2001 involving the '446 Patent, in which Bayer, but not the Company, was a party, the U.S. District Court for the Northern District of Georgia found against Bayer on the issue of infringement and held that the proper test to
determine infringement was to compare the nifedipine crystals' particle size in the bulk raw material, rather than in the finished tablets, with the range recited in the patent claims.  Based on these decisions (which are being appealed by Bayer) Biovail
has filed a motion for summary judgment of non-infringement in the Company's two ANDA cases (60 mg. and 30 mg.) in the U.S. District Court for the District of Puerto Rico, asserting that the Puerto Rico court is barred from coming to a contrary conclusion
by the doctrine of collateral estoppel.  Bayer and the Company have responded by asking the Puerto Rico court to stay, rather than dismiss, these two cases pending resolution of Bayer's appeal of the two Georgia decisions.

During 2000, Teva began commercial sale in the United States of Biovail's 60 mg. extended-release nifedipine tablets alleged to be bioequivalent to the Company's 60 mg. Procardia XL tablets.  On February 16, 2001, Bayer AG, Bayer Corporation,
and Pfizer Inc. sued Biovail Corporation, Biovail Laboratories, Inc., and Teva Pharmaceuticals USA, Inc., in the U.S. District Court for the District of Puerto Rico for infringement of Bayer's U.S. Patent 5,264,446 by this actual commercial product.

On April 2, 1998, the Company received notice from Lek U.S.A. Inc. of its filing of an ANDA for a 60 mg. formulation of nifedipine alleged to be bioequivalent to Procardia XL. On May 14, 1998, Bayer and Pfizer commenced suit in the U.S.
District Court for the District of New Jersey against Lek for infringement of Bayer's U.S. Patent 5,264,446, as well as for infringement of a second Bayer patent, 4,412,986 relating to combinations of nifedipine with certain polymeric materials.
Plaintiffs amended the complaint on November 10, 1998, limiting the action to infringement of U.S. Patent 4,412,986. On January 19, 1999, Lek filed a motion to dismiss the complaint alleging non-infringement of U.S. Patent 4,412,986. Pfizer responded to
this motion and oral argument was held in abeyance pending a settlement conference. In September 1999, a settlement agreement was entered into among the parties staying this litigation until the expiration of U.S. Patent 4,412,986 on November 2, 2000.
This suit has now been dismissed.

On February 10, 1999, the Company received a notice from Lek U.S.A. of its filing of an ANDA for a 90 mg. formulation of nifedipine alleged to be bioequivalent to Procardia XL. On March 25, 1999, Bayer and Pfizer commenced suit in the U.S.
District Court for the District of New Jersey against Lek for infringement of the same two Bayer patents originally asserted against Lek's 60 mg. formulation. This case was also the subject of a settlement conference. In September, 1999, a settlement
agreement was entered into among the parties staying this litigation until the expiration of U.S. Patent 4,412,986 on November 2, 2000. This suit has now been dismissed.

On November 9, 1998, Pfizer received an ANDA notice letter from Martec Pharmaceutical, Inc. for generic versions (30 mg., 60 mg., 90 mg.) of Procardia XL. On or about December 18, 1998, Pfizer received a new ANDA certification letter stating
that the ANDA had actually been filed in the name of Martec Scientific, Inc. On December 23, 1998, Pfizer brought an action against Martec Pharmaceutical, Inc. and Martec Scientific, Inc. in the U.S. District Court for the Western District of Missouri for
infringement of Bayer's patent relating to nifedipine of a specific particle size. On January 26, 1999, a second complaint was filed against Martec Scientific in the U.S. District Court for the Western District of Missouri based on Martec's new ANDA
certification letter. Martec filed its response to this complaint on February 26, 1999. These actions were settled and dismissed on consent on July 6, 2000.

On September 26, 2000, Pfizer received an ANDA notice letter from Andrx Pharmaceuticals, Inc. for a generic version of 60 mg. Procardia XL. On November 9 Bayer and Pfizer brought suit against Andrx in the U.S. District Court for the Southern
District of Florida for infringement of Bayer's U.S. Patent 5,264,446.  On February 12, 2001, the Company received another ANDA notice letter from Andrx, this time for a generic version of 30 mg. Procardia XL.  This litigation has now been settled in a settlement agreement that encompasses both the 60 mg. and 30 mg. Andrx products.

Pfizer filed suit on July 8, 1997, against the FDA in the U.S. District Court for the District of Columbia, seeking a declaratory judgment and injunctive relief enjoining the FDA from processing Mylan's ANDA or any other ANDA submission referencing Procardia XL that uses a different extended-release mechanism. Pfizer's suit alleges that extended-release mechanisms that are not identical to the osmotic pump mechanism of Procardia XL constitute different dosage forms requiring the filing and approval
of suitability petitions under the Food Drug and Cosmetics Act before the FDA can accept an ANDA for filing. Mylan intervened in Pfizer's suit. On March 31, 1998, the court granted the government's motion for summary judgment against the Company. On July
16, 1999, the D.C. Court of Appeals dismissed the appeal on the ground that since the FDA had not approved any ANDA referencing Procardia XL that uses a different extended-release mechanism than the osmotic pump mechanism of Procardia XL, it was premature to maintain this action, stating that Pfizer has the right to bring such an action if, and when, the FDA approves
such an ANDA. Subsequent to FDA's final approval of Mylan's ANDA, on December 18, 1999, Pfizer filed suit against FDA in the United States District Court for the District of Delaware. The suit alleges that FDA unlawfully approved Mylan's 30 mg. extended
release product because FDA had not granted an ANDA suitability petition reflecting a difference in dosage form from Procardia XL. As a result of the settlement agreement with Mylan, Pfizer and the FDA have agreed to dismiss this suit without prejudice.

On February 22, 2001, Biovail Corporation and Biovail Laboratories, Inc. filed suit against Pfizer Inc., Mylan Laboratories, Inc., and Mylan Pharmaceuticals, Inc., in the U.S. District Court for the Eastern District of Virginia, claiming that the
February 2000 settlement agreement between Pfizer and Mylan relating to a 30 mg. extended-release nifedipine tablet product is in violation of Section 1 of the Sherman Antitrust Act.  At the defendants' motion this suit has been transferred to the U.S.
District Court for the District of West Virginia.

As has been publicly reported, the Federal Trade Commission is conducting a review of brand-name and generic drug litigations, settlements and agreements. As part of this overall review, documents in connection with certain of the litigations set
forth above have been provided to the Commission.

Zoloft Patents

On December 17, 1999, the Company received notice of the filing of an ANDA by Zenith Goldline Pharmaceuticals for 50 mg. and 100 mg. tablets of sertraline hydrochloride alleged to be bioequivalent to Zoloft. Zenith has certified to the FDA
that it will not engage in the manufacture, use or sale of sertraline hydrochloride until the expiration of Pfizer's U.S. Patent 4,536,518, which covers sertraline per se and expires December 30, 2005. Zenith has also alleged in its certification to the
FDA that the manufacture, use and sale of Zenith's product will not infringe Pfizer's U.S. Patent 4,962,128, which covers methods of treating an anxiety-related disorder or Pfizer's U.S. Patent 5,248,699, which covers a crystalline polymorph of sertraline
hydrochloride. These patents expire in November 2009 and August 2012, respectively. On January 28, 2000, the Company filed a patent infringement action against Zenith Goldline and its parent Ivax Corporation in the U.S. District Court for the District of
New Jersey for infringement of the '128 and '699 Patents. Zenith Goldline filed its answer on March 10, 2000, denying infringement. Discovery is in progress.  No trial date has been set.

Fluconazole Patent

On February 1, 2000, the Company received notice of the filing of an ANDA by Novopharm Limited for 50 mg., 100 mg., 150 mg. and 200 mg. tablets of fluconazole alleged to be bioequivalent to Diflucan. Novopharm has certified to the FDA its
position that the Company's U.S. Patent 4,404,216, which covers fluconazole, is invalid. This patent expires in January 2004. On March 10, 2000, the Company filed a patent infringement action under the '216 Patent against Novopharm in the U.S. District
Court for the Northern District of Illinois. Discovery is ongoing. No trial date has been set.

Neurontin Patents

In April 1998 Warner-Lambert received an ANDA notice from Purepac Pharmaceutical Co., relating to 100 mg., 300 mg., and 400 mg. gabapentin capsules, which certified Purepac's opinion that the proposed Purepac products do not infringe
Warner-Lambert's U.S. Patent 4,894,476 directed to gabapentin monohydrate and that the '476 Patent is invalid in view of the prior art. In June 1998 Warner-Lambert filed a lawsuit in the U.S. District Court for the District of New Jersey against Purepac
and Faulding Inc., its parent company, for infringement of the '476 Patent and U.S. Patent 5,084,479 directed to a method for treating neurodegenerative diseases with compounds including gabapentin. The defendants filed a counterclaim for unfair
competition under New Jersey law based upon alleged improper listing of the'476 Patent in the FDA "Orange Book" and alleged absence of probable cause for filing suit on the '476 and '479 Patents. In August 1999 the court denied the defendants'
motion for summary judgment of non-infringement of the '476 and '479 Patents, and in December 2000 the court denied the Company's motion for summary judgment dismissing the defendants' counterclaim for unfair completion but bifurcated this counterclaim
from the patent infringement claims for discovery and trial. Discovery on the patent infringement claims has been completed and the defendants, on April 16, renewed their motion for summary judgment of non-infringement of the two patents-in-suit.

In May 1998 Warner-Lambert received two ANDA notice letters from TorPharm, Inc., relating to 100 mg., 300 mg., and 400 mg. gabapentin capsules, which certified TorPharm's opinion that the proposed products of its Apotex Corp. agent do not infringe
Warner-Lambert's U.S. Patents 4,894,476 and 5,084,479. Warner-Lambert filed a lawsuit in the U.S. District Court for the Northern District of Illinois for infringement of the '476 and '479 Patents. In April 1999 the court denied the defendants' motion for
summary judgment of non-infringement of the '479 Patent. Discovery has been completed.  On March 2 the court granted the defendants' motion for summary judgment of non-infringement of the '476 Patent.  The Company has moved to transfer this suit to the
U.S. District Court for the District of New Jersey, and the defendants have renewed their motion for summary judgment of non-infringement of the '479 Patent.

In November 1999 Warner-Lambert received an ANDA notice letter from Faulding Inc., related to 600 mg. and 800 mg. gabapentin tablets, which certified Faulding's opinion that the proposed products of its Purepac Pharmaceutical Co. subsidiary do not
infringe the '476 Patent and that this patent is invalid in view of the prior art. In December 1999 Warner-Lambert filed a lawsuit in the U.S. District Court for the District of New Jersey for infringement of the '476 and '479 Patents. The defendants
filed counterclaims for unfair competition under New Jersey law and federal antitrust law violations, and in December 2000 the Court denied the Company's motion to dismiss these counterclaims. Discovery has been completed and the defendants, on April 16,
moved for summary judgment of non-infringement of the two patents-in-suit.

In November 1999 Apotex Corp. and Apotex Inc. filed suit against Warner-Lambert in the U.S. District Court for the Northern District of Illinois alleging federal antitrust violations. Warner-Lambert filed a motion to dismiss the action which was
granted. Apotex subsequently added antitrust counterclaims to the copending gabapentin capsule patent infringement suit in the Northern District of Illinois. This counterclaim has been stayed pending resolution of the patent infringement issues.

In February 1999 Geneva Pharmaceuticals, Inc., filed an action in the U.S. District Court for the Eastern District of Michigan against Warner-Lambert for a declaratory judgment that its proposed 100 mg., 300 mg. and 400 mg. gabapentin capsule products
do not infringe the '476 Patent directed to gabapentin monohydrate. This action has been transferred to the U.S. District Court for the District of New Jersey. Discovery has been completed. The Company's motion to dismiss this complaint and Geneva's
motion for summary judgment of non-infringement are pending.

On April 25, 2000, U.S. Patent 6,054,482, which claims anhydrous gabapentin formulations containing low levels of lactam and mineral acid, was issued to Warner-Lambert's Godecke Aktiengesellschaft subsidiary (Godecke). This patent was listed in the
FDA's "Orange Book" under the Company's Neurontin capsule and tablet products on the same day. On April 28 Purepac Pharmaceutical Co. (Purepac) and Faulding Inc. filed suit in the U.S. District Court for the District of New Jersey against Warner-Lambert and Godecke for a declaratory
judgment that the '482 Patent is invalid and would not be infringed by Purepac's proposed gabapentin capsule and tablet products. On June 15 Warner-Lambert and Godecke moved to dismiss the complaint, and also filed suit in the same court against Purepac
and Faulding Inc. seeking orders enjoining them from pursuing their declaratory judgment action and compelling them to submit appropriate certifications to the FDA regarding the '482 Patent. This suit also alleges infringement of the '482 Patent. On June
15 Warner-Lambert received a notice letter from Purepac and Faulding Inc. which certified their position that the proposed Purepac gabapentin tablet and capsule products do not infringe the '482 Patent. On July 20, Pfizer, Warner-Lambert, and Godecke
filed another suit in federal court in New Jersey against Purepac and Faulding Inc. for infringement of the '482 Patent. The defendant's answer to this last suit includes counterclaims for antitrust violations under the Sherman Act and unfair competition.
The three suits were consolidated and the April 28 suit was dismissed by the court. On November 27 the Company filed a motion to dismiss the counterclaims in the July 20 suit and on January 16, 2001, the defendants filed a motion for summary judgment of
non-infringement.  The Company's brief in opposition to this motion for summary judgment was filed on April 12. Discovery is in progress.

On June 15, 2000, Warner-Lambert received a notice letter from TorPharm, Inc., certifying its opinion that the proposed gabapentin capsule products of its Apotex Corp. agent do not infringe the '482 Patent. On July 20 Pfizer, Warner-Lambert, and
Godecke filed suit in the U.S. District Court for the Northern District of Illinois for infringement of the '482 Patent. The defendant's answer includes counterclaims for antitrust violations under the Sherman Act. On November 6 the Company filed a motion
to dismiss these counterclaims.  On March 7 the defendants filed a motion for summary judgment of non-infringement.

On July 25, 2000, Warner-Lambert received a notice letter from Teva Pharmaceuticals USA (Teva), relating to 600 mg. and 800 mg. gabapentin tablets, which certified Teva's opinion that its proposed products do not infringe the '482 Patent, and on
September 7 a similar notice letter relating to 100 mg., 300 mg., and 400 mg. gabapentin capsules, which also stated Teva's opinion that the '482 Patent is invalid. On August 24 and September 20, Pfizer, Warner-Lambert, and Godecke filed two lawsuits, for
tablets and capsules respectively, in the U.S. District Court for the District of New Jersey against Teva and Teva Pharmaceuticals Industries Ltd. for infringement of the '482 Patent.

On October 2, 2000, the Company filed a motion with the Federal Judicial Panel on Multidistrict Litigation to consolidate all of the above-identified patent cases involving U.S. Patent 6,054,482 for pretrial proceedings in the U.S. District Court for
the District of New Jersey. Purepac/Faulding Inc. and Apotex/TorPharm filed oppositions. This motion was granted on February 5.  Patent infringement suits (described below) based on the '482 Patent against Zenith/Ivax and Eon Labs have subsequently been
joined into these consolidated proceedings.

In November 2000, Warner-Lambert and Godecke received notice letters from Zenith Goldline Pharmaceuticals, Inc., relating to its proposed 100 mg., 300 mg. and 400 mg. gabapentin capsules, certifying Zenith's opinion that the Company's '482 Patent is
invalid. On December 14, Pfizer Inc., Warner-Lambert and Godecke filed suit in the U.S. District Court for the District of New Jersey against Zenith Laboratories, Inc., Zenith Goldline Pharmaceuticals, Inc. and Ivax Corporation (Zenith's parent company)
for infringement of the '482 Patent. In December 2000 Warner-Lambert received a notice letter from Zenith Goldline Pharmaceuticals, Inc. notifying Warner-Lambert that Zenith had filed an ANDA on 600 mg. and 800 mg. gabapentin tablets and certifying
Zenith's opinion that the '482 Patent is invalid, and also that the '476 Patent and the '479 Patent are both invalid and would not be infringed by the manufacture, use or sale of the proposed Zenith tablet product. In January and February the Company
filed suits against Zenith Laboratories, Inc., Zenith Goldline Pharmaceuticals, Inc. and Ivax Corporation in the U.S. District Court for the District of New Jersey for infringement of the '482 Patent (January suit) and the '476 and '479 Patents (February
suit).  In February 2001, the Company received a comparable notice letter from Zenith directed to proposed 100 mg., 300 mg. and 400 mg. gabapentin tablet products.  On March 30 the Company filed two suits against Zenith Laboratories, Inc., Zenith Goldline
Pharmaceuticals, Inc., and Ivax Corporation in the U.S. District Court for the District of New Jersey for infringement of the '482 Patent, and the '476 and '479 Patents, respectively.

In February 2001, Warner-Lambert received a notice letter from Eon Labs Manufacturing, Inc. relating to its proposed 100 mg., 300 mg. and 400 mg. gabapentin capsule products, certifying Eon's opinion that the Company's '482, '476 and '479 Patents
would not be infringed by the manufacture, use or sale of the proposed Eon products.  On March 20 the Company filed suit against Eon Labs in the U.S. District Court for the Eastern District of New York for infringement of the '482 Patent.

Celebrex Litigation

On April 11, 2000, the University of Rochester filed a patent infringement action in the U.S. District Court for the Western District of New York against the Company, G.D. Searle & Co., Inc., Monsanto Co., and Pharmacia Corp., under its U.S.
Patent 6,048,850, relating to the use of COX-2 inhibiting compounds. It is alleged that sales of Celebrex infringe the broad method of use claims of this patent. The Company has answered denying infringement. Discovery is in progress. No trial date has been set.

Quinapril Patents

In January 1999 Warner-Lambert received a letter from Teva Pharmaceuticals USA informing it that Teva had filed an ANDA on 40 mg. quinapril hydrochloride tablets allegedly bioequivalent to the Company's Accupril product. This letter also
certified Teva's opinion that the Company's U.S. Patent 4,473,450, which is directed to stable formulations of ACE inhibitor compounds and expires in February 2007, is invalid, and further informed us that manufacture, use and sale of the proposed product
would await expiration of the basic product patent on quinapril hydrochloride (U.S. Patent 4,344,949) in October 2002. In March 1999 Warner-Lambert filed suit against Teva Pharmaceuticals USA in the U.S. District Court for the District of New Jersey for
infringement of the '450 Patent. Discovery is in progress. No trial date has yet been scheduled.

Schneider Catheter Litigation

On July 28, 2000, Dr. Tassilo Bonzel filed a suit against the Company and various currently or formerly affiliated codefendants in Minnesota state court alleging breach of contract, fraudulent transfer of his license agreement with Schneider
(Europe) AG, unjust enrichment, breach of fiduciary duty, tortious interference with contractual relationship, and civil conspiracy, and seeking a declaratory judgment that Dr. Bonzel is free to terminate the aforementioned license agreement. The claims
arise from the Company's 1998 sale of the Schneider companies to Boston Scientific Corporation (BSC), which is named in Dr. Bonzel's complaint as an involuntary plaintiff. On August 28 the Company and BSC removed the suit to the U.S. District Court for
the District of Minnesota and on August 30 Dr. Bonzel filed a motion to remand it to state court, which the Company and BSC opposed. This motion to remand was granted on February 6. Additionally, on September 18 BSC filed a motion with the federal court
in Minnesota to be dismissed from this action as an involuntary plaintiff. This motion was also granted on February 6.  On September 5 BSC filed an action in the U.S. District Court for the District of Massachusetts for a declaratory judgment that its
license with Dr. Bonzel cannot be revoked and thus that it would not be infringing Dr. Bonzel's patents on rapid exchange catheters.  This Massachusetts action has been dismissed on the basis of lack of justiciable case or controversy.  BSC has been added
as a codefendant party in the Minnesota state court action and discovery has been commenced.

Trademark and Unfair Competition

Trovan Trademark

On September 22, 1999, the jury in a trademark-infringement litigation brought against Pfizer in the U.S. District Court for the Central District of California by Trovan Ltd. and Electronic Identification Devices, Ltd., relating to use of the Trovan mark for trovafloxacin issued a verdict in favor of the plaintiffs with respect to liability, holding that the Company had infringed Trovan Ltd.'s mark and had acted in bad faith. Following a further damage trial, on October 12, 1999, the jury
awarded Trovan Ltd. a total of $143 million in damages, comprising $5 million actual damages, $3 million as a reasonable royalty and $135 million in punitive damages. The court held a hearing on December 27, 1999, on whether to award the plaintiffs
profits based on the Company's sales of Trovan and, if so, the amount of same. On February 24, 2000, the court entered judgment on the jury verdict and enjoined the Company's use of the Trovan mark effective October 16, 2000. The plaintiff's request to be awarded the Company's
profits from Trovan sales and for treble damages was denied. Following a hearing on March 24, 2000 the court vacated its previous rulings based on the jury verdicts, including the injunction against continued use of Trovan and the cancellation of the
Company's U.S. trademark registration, and granted the motion for mistrial. The court also granted the Company's remittitur motions, eliminating the "reasonable royalty" award ($3 million) and reducing the maximum damages award from $8 million
to $500,000 and the maximum enhanced award from $135 million to $1.5 million. The plaintiffs have appealed to the Ninth Circuit Court of Appeals the district court's refusal to enjoin the Company's continued use of the Trovan trademark. Additionally, the district court (at the plaintiffs' request) has certified certain legal issues to the Ninth Circuit for determination before the case is retried.

Zyrtec Litigation

On October 5, 1998, Schering-Plough, Inc., sought, in the U.S. District Court for the Southern District of New York, and was denied, a temporary restraining order and moved for a temporary injunction based on its allegations that Pfizer breached a
1996 settlement agreement arising from an earlier Lanham Act suit involving the promotion of Zyrtec, in competition with Schering's Claritin. On appeal to the Second Circuit Court of Appeals, the decision denying Schering's request for a preliminary injunction was vacated and the case was remanded to the District Court. The Second Circuit
found that the District Court should have made more detailed findings on the reliability of the surveys used to support the motion. Following a hearing, the District Court entered a preliminary injunction which prohibits Pfizer from claiming that Zyrtecis non-sedating or essentially non-sedating. The matter has been resolved in advance of trial by making permanent the preliminary injunction.



Products Liability Litigation

Shiley Incorporated

As previously disclosed, a number of lawsuits and claims have been brought against the Company and Shiley Incorporated, a wholly owned subsidiary, alleging either personal injury from fracture of 60 degree or 70 degree Shiley Convexo Concave
("C/C") heart valves, or anxiety that properly functioning implanted valves might fracture in the future, or personal injury from a prophylactic replacement of a functioning valve.

In an attempt to resolve all claims alleging anxiety that properly functioning valves might fracture in the future, the Company entered into a settlement agreement in January 1992 in Bowling v. Shiley, et al., a case brought in the U.S. District Court
for the Southern District of Ohio, that established a worldwide settlement class of people with C/C heart valves and their spouses, except those who elected to exclude themselves. The settlement provided for a Consultation Fund of $90 million, which was
fixed by the number of claims filed, from which valve recipients received payments that are intended to cover their cost of consultation with cardiologists or other health care providers with respect to their valves. The settlement agreement established a
second fund of at least $75 million to support C/C valve-related research, including the development of techniques to identify valve recipients who may have significant risk of fracture, and to cover the unreimbursed medical expenses that valve recipients
may incur for certain procedures related to the valves. The Company's obligation as to coverage of these unreimbursed medical expenses is not subject to any dollar limitation. Following a hearing on the fairness of the settlement, it was approved by the
court on August 19, 1992, and all appeals have been exhausted.

Generally, plaintiffs in heart valve litigations seek money damages. Based on the experience of the Company in defending these claims to date, including insurance proceeds and reserves, the Company is of the opinion that such actions should not have a
material adverse effect on the financial position or results of the Company. Litigation involving insurance coverage for the Company's heart valve liabilities has been resolved.

Rezulin

Rezulin, a Warner-Lambert oral therapy for the treatment of type 2 diabetes, was launched in the United States in March 1997 and withdrawn from the market in March 2000, following reports of liver damage, including liver failure requiring liver
transplants, and death. The package insert for Rezulin was revised in October 1997 in response to post-marketing reports of adverse liver events. The revised labeling recommended that physicians monitor liver enzymes periodically. The labeling subsequently was changed three times to increase
the recommended frequency of liver enzyme monitoring and to add other information regarding indications and adverse liver events.

Since Rezulin's withdrawal from the market, a number of suits and claims against Warner-Lambert (and in some instances against the Company as well) have been filed. As of April 13, 2001, 49 Federal and 18 state class action suits have been
filed seeking medical monitoring; five Federal and five state class actions seek damages or restitution; individual Federal and state suits have been filed seeking damages or restitution for personal injuries on behalf of about 2,800 Rezulin patients; and claims on behalf of 565 Rezulin patients have been received.

The cases filed in or removed to Federal courts have been consolidated for certain pretrial purposes in the U.S. District Court for the Southern District of New York by order of the Judicial Panel on Multi-District Litigation, and the class actions
seeking medical monitoring have been consolidated under a single class complaint. Most of these cases are in early stages of discovery.

The Company is defending these actions and, considering its insurance and reserves, is of the opinion that these actions should not have a material adverse effect on the financial position or results of the Company.

Trovan

During May and June, 1999, the FDA and the European Union's Committee for Proprietary Medicinal Products (CPMP) reconsidered the approvals to market Trovan, a broad-spectrum antibiotic, following post-market reports of severe adverse liver
reactions to the drug. On June 9, 1999, the Company announced that, regarding the marketing of Trovan in the United States, it had agreed to restrict the indications, limit product distribution, make certain other labeling changes and communicate revised warnings to health care professionals in the United States. On July 1, 1999, Pfizer
received the opinion of the CPMP recommending a one-year suspension of the licenses to market Trovan in the European Union. The CPMP opinion has been finalized in a Final Decision by the European Commission.

Since June 1999, suits in both Federal and state courts, and unfiled claims, on behalf of approximately 40 Trovan patients have been received by the Company alleging liver injuries due to ingestion of Trovan. Approximately half of these
matters have been resolved. There are also three purported state court class actions in South Carolina seeking damages and injunctive relief on behalf of Trovanpatients and their spouses and one purported class action in Nigeria arising out of a clinical trial during a meningitis epidemic in 1996. The cases are in early stages of discovery.

The Company is defending these actions and, considering its insurance and reserves, is of the opinion that these actions should not have a material adverse effect on the financial position or results of the Company.

Asbestos Matters

Through the early 1970s, Pfizer Inc. (Minerals Division) and Quigley Company, Inc. ("Quigley"), a wholly owned subsidiary, sold a minimal amount of one construction product and several refractory products containing some asbestos. These
sales were discontinued thereafter. Although these sales represented a minor market share, the Company has been named as one of a number of defendants in numerous lawsuits. These actions, and actions related to the Company's sale of talc products in the
past, claim personal injury resulting from exposure to asbestos-containing products, and nearly all seek general and punitive damages. In these actions, the Company or Quigley is typically one of a number of defendants, and both have been members of the
Center for Claims Resolution (the "CCR"), a joint defense organization of several defendants that has been defending these claims. The Company and Quigley have been responsible for varying percentages of defense and liability payments for all
members of the CCR. With the reformation and/or dissolution of CCR, the Company and Quigley will defend the litigation separately from other CCR members. A number of cases alleging property damage from asbestos-containing products installed in buildings
have also been brought against the Company, but most have been resolved and none are active.

As of April 1, 2001, there were 66,910 personal injury claims pending against Quigley and 39,756 such claims against the Company (excluding those that are inactive or have been settled in principle), and 67 talc cases against the Company.

The Company believes that its costs incurred in defending and ultimately disposing of the asbestos personal injury claims, as well as the property damage and talc claims, will be largely covered by insurance policies issued by several primary
insurance carriers and a number of excess carriers that have agreed to provide coverage, subject to deductibles, exclusions, retentions and policy limits. Litigation against excess insurance carriers seeking damages and/or declaratory relief to secure
their coverage obligations has been largely resolved.

From 1967 to 1982, a Warner-Lambert subsidiary owned American Optical Company, which at certain times manufactured a line of personal protective clothing and respirators for use in general industrial settings. Certain of the protective clothing items
(e.g., certain gloves) contained asbestos. American Optical discontinued production of protective clothing in 1976, and sold its protective clothing business in its entirety in 1977. In May 1982, Warner-Lambert sold American Optical. As part of that sale,
the Warner-Lambert subsidiary agreed to indemnify the purchaser against product liability claims arising out of alleged use or exposure to American Optical products up to the date of closing.

As of April 1, 2001, American Optical was named a defendant in lawsuits involving approximately 46,075 individual plaintiffs. Approximately two-thirds of these lawsuits involve claims for asbestos-related disease developed as a result of exposure to
asbestos-containing protective clothing allegedly manufactured by American Optical. The remaining one-third consists of claims for silica-related disease developed as a result of exposure to silica while using allegedly defective respirators manufactured
by American Optical.

Based on the Company's experience in defending the claims to date and considering its insurance and reserves, the Company is of the opinion that the actions should not have a material adverse effect on the financial position or results of the Company.

Rimadyl

In October 1999 the Company was sued in an action seeking unspecified damages, costs and attorney's fees on behalf of a purported class of people whose dogs had suffered injury or death after ingesting Rimadyl, an antiarthritic medication
for older dogs. The suit, which was filed in state court in South Carolina, is in the early pretrial stages. The Company is defending this action and is of the opinion that it should not have a material adverse effect on the financial position or results
of the Company.

Consumer Litigation

Plax

FDA administrative proceedings relating to Plax are pending, principally an industry-wide call for data on all anti-plaque products by the FDA. The call-for-data notice specified that products that have been marketed for a material time and
to a material extent may remain on the market pending FDA review of the data, provided the manufacturer has a good faith belief that the product is generally recognized as safe and effective and is not misbranded. The Company believes that Plax satisfied these requirements and prepared a response to the FDA's request, which was filed on June 17, 1991. This filing, as well as the filings of other manufacturers, is still under review and is currently being considered by an FDA Advisory
Committee. The Committee has issued a draft report recommending that plaque removal claims should not be permitted in the absence of data establishing efficacy against gingivitis. The process of incorporating the Advisory Committee recommendations into a
final monograph is expected to take several years. If the draft recommendation is ultimately accepted in the final monograph, although it would have a negative impact on sales of Plax, it will not have a material adverse effect on the sales, financial position or results of the Company.

On January 15, 1997, an action was filed in Circuit Court, Chambers County, Alabama, purportedly on behalf of a class of consumers, variously defined by the laws or types of laws governing their rights and encompassing residents of up to 47 states.
The complaint alleges that the Company's claims for Plax were untrue, entitling them to a refund of their purchase price for purchases since 1988.  The court has issued an order denying class certification.

Pediculicides

Since December 1998, five actions have been filed, in state courts in Texas, California, Illinois and Louisiana, purportedly on behalf of statewide or nationwide classes of consumers who allege that Pfizer's and/or Warner-Lambert's and other
manufacturers' advertising and promotional claims for Pfizer's Rid and Warner-Lambert's Nixand other pediculicides were untrue, entitling them to refunds, other damages and/or injunctive relief. One of the Texas cases has been voluntarily dismissed, the Louisiana case has been resolved, and we obtained
summary judgment in the California case. Proceedings in the other Texas case and Illinois cases are still in early stages.

The Company is defending these actions and is of the opinion that they should not have a material adverse effect on the financial position or results of the Company.

Desitin

In December 1999 and January 2000, two suits were filed in California state courts against the Company and other manufacturers of zinc oxide-containing powders. The first suit was filed by the Center for Environmental Health and the second was
filed by an individual plaintiff on behalf of a purported class of purchasers of baby powder products. The suits generally allege that the label of Desitin powder violates California's "Proposition 65" by failing to warn of the presence of lead, which is alleged to be a carcinogen. In January, 2000, the Company received a notice from a California environmental group alleging that the
labeling of Desitin ointment and powder also violates Proposition 65 by failing to warn of the presence of cadmium, which is alleged to be a carcinogen. Several other manufacturers of zinc oxide-containing topical baby products have received similar notices.
The Company believes that the labeling for Desitin complies with applicable legal requirements.

Diabinese (Brazil)

In June, the Ministry of Justice of the State of Sao Paulo, Brazil, commenced a civil public action against the Company's Brazilian subsidiary, Laboratorios Pfizer Ltda. ("Pfizer Brazil") asserting that during a period in 1991 Pfizer
Brazil withheld sale of the pharmaceutical product Diabinese in violation of antitrust and consumer protection laws. The action sought the award of moral, economic and personal damages to individuals and the payment to a public reserve fund. In February 1996, the trial court issued a decision
holding Pfizer Brazil liable. The trial court's opinion also established the amount of moral damages for individuals who might make claims later in the proceeding and set out a formula for calculating the payment into the public reserve fund which could
have resulted in a sum of approximately $88 million. Pfizer Brazil appealed this decision. In September 1999, the appeals court issued a ruling upholding the trial court's decision as to liability. However, the appeals court decision overturned the trial
court's decision concerning damages, ruling that criteria to apply in the calculation of damages, both as to individuals and as to payment of any amounts to the reserve fund, should be established only in a later stage of the proceeding. The Company's
appeal from the ruling is still pending.  The Company believes that this action should not have a material adverse effect on the financial position or results of the Company.

Employment Litigation

A wholly-owned subsidiary of Warner-Lambert has been named as a defendant in class actions filed in Puerto Rico Superior Court by current and former employees from the Vega Baja, Carolina and Fajardo plants, as well as Kelly Services temporary
employees assigned to those plants. The lawsuits seek monetary relief for alleged violations of local statutes and decrees relating to meal period payments, minimum wage, overtime and vacation pay. The Company is defending these actions and is of the
opinion that they should not have a material adverse effect on the financial position or results of the Company.

Antitrust

Brand-Name Prescription Drugs Antitrust Litigation

In 1993, both Pfizer and Warner-Lambert were named, together with numerous other manufacturers of brand-name prescription drugs and certain companies that distribute brand-name prescription drugs, in suits in federal and state courts brought by
various groups of retail pharmacy companies, alleging that the manufacturers violated the Sherman Act by agreeing not to give retailers certain discounts and that the failure to give such discounts violated the Robinson Patman Act. A class action was
brought on the Sherman Act claim, as well as additional actions by approximately 3,500 individual retail pharmacies and a group of chain and supermarket pharmacies (the "individual actions") on both the Sherman Act and Robinson Patman Act
claims. A retailer class was certified in 1994 (the "Federal Class Action"). In 1996, fifteen manufacturer defendants, including Pfizer and Warner-Lambert, settled the Federal Class Action. Pfizer's share was $31.25 million and Warner-Lambert's
share was $15.1 million. Trial began in September 1998 for the class case against the non-settlers, and the District Court also permitted the opt-out plaintiffs to add the wholesalers as named defendants in their cases. The District Court dismissed the
case at the close of the plaintiffs' evidence. The plaintiffs appealed and, on July 13, 1999, the Court of Appeals upheld most of the dismissal but remanded on one issue, while expressing doubts that the plaintiffs could prove any damages. The District
Court has since opined that the plaintiffs cannot prove such damages.

Retail pharmacy cases also have been filed in state courts in five states, and consumer class actions were filed in state courts in fourteen states and the District of Columbia alleging injury to consumers from the failure to give discounts to retail
pharmacy companies. Most of the consumer class actions have been settled in principle.

In addition to its settlement of the retailer Federal Class Action (see above), Pfizer and Warner-Lambert have also settled several major opt-out retail cases, and along with other manufacturers: (1) have entered into agreements to settle all
outstanding consumer class actions, which settlements are going through the approval process in the various courts in which the actions are pending; and (2) have settled the California consumer case.

The Company believes that these brand-name prescription drug antitrust cases, which generally seek damages and certain injunctive relief should not have a material adverse effect on the financial position or results of the Company.

The Federal Trade Commission opened an investigation focusing on the pricing practices at issue in the above pharmacy antitrust litigation. In July 1996, the Commission issued subpoenas for documents to both Pfizer and Warner-Lambert, among others, to
which both responded. A second subpoena was issued to both companies for documents in May 1997 and both again responded. We are not aware of any further activity.

Former Food Science Division

In 1999, the Company pleaded guilty to one count of price fixing of sodium erythorbate from July 1992 until December 1994, and one count of market allocation of maltols from December 1989 until December 1995, and paid a total fine of $20 million.
The activities at issue involved the Company's former Food Science Group, a division that manufactured food additives and that the Company divested in 1996. The Department of Justice has stated that no further antitrust charges will be brought against the
Company relating to the former Food Science Group, that no antitrust charges will be brought against any current director, officer or employee of the Company for conduct related to the products of the former Food Science Group, and that none of the
Company's current directors, officers or employees was aware of any aspect of the activity that gave rise to the violations. Five purported class action suits involving these products have been filed against the Company; two in California State Court, and
three in New York Federal Court, all of which have been settled in principle. The Company does not believe that this plea and settlement, or the civil litigation involving these products, should have a material adverse effect on the financial position or
results of the Company.

Environmental Matters

The operations of the Company are subject to federal, state, local and foreign environmental laws and regulations. Under the Comprehensive Environmental Response Compensation and Liability Act of 1980, as amended ("CERCLA" or "
Superfund"), the Company has been designated as a potentially responsible party by the United States Environmental Protection Agency with respect to certain waste sites with which the Company may have had direct or indirect involvement. Similar
designations have been made by some state environmental agencies under applicable state Superfund laws. Such designations are made regardless of the extent of the Company's involvement. The Company owns or previously owned several sites for which it may
be the sole responsible party. There are also claims that the Company may be a responsible party or participant with respect to several waste site matters in foreign jurisdictions. Such claims have been made by the filing of a complaint, the issuance of
an administrative directive or order, or the issuance of a notice or demand letter. These claims are in various stages of administrative or judicial proceedings. They include demands for recovery of past governmental costs and for future investigative or
remedial actions. In many cases, the dollar amount of the claim is not specified. In most cases, claims have been asserted against a number of other entities for the same recovery or other relief as was asserted against the Company. The Company is
currently participating in remedial action at a number of sites under federal, state, local and foreign laws.

To the extent possible with the limited amount of information available at this time, the Company has evaluated its responsibility for costs and related liability with respect to the above sites and is of the opinion that the Company's liability with
respect to these sites should not have a material adverse effect on the financial position or results of the Company. In arriving at this conclusion, the Company has considered, among other things, the payments that have been made with respect to the
sites in the past; the factors, such as volume and relative toxicity, ordinarily applied to allocate defense and remedial costs at such sites; the probable costs to be paid by the other potentially responsible parties; total projected remedial costs for a
site, if known; existing technology; and the currently enacted laws and regulations. The Company anticipates that a portion of these costs and related liability will be covered by available insurance.

FDA Required Post-Marketing Reports

In April 1996, Pfizer received a Warning Letter from the FDA relating to the timeliness and completeness of required post-marketing reports for pharmaceutical products. The letter did not raise any safety issue about Pfizer drugs. The Company has been
implementing remedial actions designed to remedy the issues raised in the letter. During 1997, the Company met with the FDA to apprise them of the scope and status of these activities. A review of the Company's new procedures was undertaken by FDA in
1999. The Company and Agency met to review the findings of this review and agreed that commitments and remedial measures undertaken by the Company related to the Warning Letter have been accomplished. The Company agreed to keep the Agency informed of its
activities as it continues to modify its processes and procedures.

Neurontin Investigation

Certain employees of Warner-Lambert were served with subpoenas in January 2000, by the U.S. Attorney's office in Boston, Massachusetts, directing them to provide testimony before a federal grand jury in Boston. The U.S. Attorney's office is conducting
an inquiry into Warner-Lambert's promotion of Neurontin. The Company is cooperating with the inquiry and cannot predict what the outcome of the investigation will be.

In addition, a former employee of Warner-Lambert has commenced a civil lawsuit in the U.S. District Court for the District of Massachusetts against Warner-Lambert, on behalf of the United States, under 31 U.S.C. 3730. The lawsuit alleges that the
company has violated the Federal False Claims Act based on certain alleged sales and marketing practices concerning its drugs Neurontin and Accupril. The Company is defending this action and is of the opinion that it should not have a material adverse effect on the financial position or results of the Company.

Merger Litigation

In November 1999, following the announcement by Warner-Lambert of its executions of the American Home Products Corporation (AHP) Merger Agreement, Pfizer filed suit against Warner-Lambert, its board of directors and AHP, seeking to invalidate certain
provisions in the AHP Merger Agreement and enjoin their implementation. Pursuant to a settlement agreement executed on February 6, 2000, in connection with the termination of the AHP Merger Agreement and the execution of the Pfizer Merger Agreement,
Warner-Lambert, AHP and Pfizer entered into settlement agreements with respect to this litigation. Shortly thereafter the litigation against AHP was dismissed with prejudice and the litigation between Pfizer and Warner-Lambert was dismissed without
prejudice.

Warner-Lambert, its Directors and AHP have been named in approximately 40 lawsuits in Delaware Chancery Court, one lawsuit in Morris County, New Jersey, and two lawsuits in federal court in New Jersey brought on behalf of purported classes of
Warner-Lambert's shareholders. These lawsuits involve allegations similar to those contained in Pfizer's lawsuit, referred to above, and contain additional allegations, including that the consideration to be paid to Warner-Lambert's shareholders in the
proposed merger with AHP was inadequate. The Company is defending these actions and is of the opinion that they should not have a material adverse effect on the financial position or results of the Company.



Tax Matters

The Internal Revenue Service has completed and closed its audits of our tax returns through 1995.

In November 1994, Belgian tax authorities notified Pfizer Research and Development Company N.V./S.A. ("PRDCO"), an indirect, wholly owned subsidiary of our company, of a proposed adjustment to the taxable income of PRDCO for fiscal year 1992.  The
proposed adjustment arises from an assertion by the Belgian tax authorities of jurisdiction with respect to income resulting primarily from certain transfers of property by our non-Belgian subsidiaries to the Irish branch of PRDCO.  In January 1995, PRDCO
received an assessment from the tax authorities for additional taxes and interest of approximately $432 million and $97 million, respectively, relating to these matters.  In January 1996, PRDCO received an assessment from the tax authorities, for fiscal
year 1993, for additional taxes and interest of approximately $86 million and $18 million, respectively. The additional assessment arises from the same assertion by the Belgian tax authorities of jurisdiction with respect to all income of the Irish branch
of PRDCO.  Based upon the relevant facts regarding the Irish branch of PRDCO and the provisions of Belgian tax laws and the written opinions of outside counsel, we believe that the assessments are without merit.

We believe that our accrued tax liabilities are adequate for all years.
