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 (accounting principles generally accepted in the United States of America) 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 and nine-month periods ended August 25, 2002 and August 26, 2001. We made certain reclassifications to the 2001 condensed consolidated financial statements to conform to the 2002 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 Business Combinations andGoodwill and Other Intangible Assets

On January 1, 2002, we adopted the provisions of Statement of Financial Accounting Standards (SFAS) No. 141, Business Combinations, and SFAS No. 142, Goodwill and Other Intangible Assets. SFAS No. 141 eliminates the pooling of interests method of accounting for business combinations initiated after June 30, 2001. The adoption of SFAS No. 141 does not impact our financial position or results of operations.

Under the provisions of SFAS No. 142, intangible assets with indefinite lives and goodwill are no longer amortized but are subject to annual impairment tests. Separable intangible assets with definite lives continue to be amortized over their useful lives. Application of the non-amortization provisions of SFAS No. 142 does not have a material effect on our quarterly or annual financial condition or results of operations. As a result of adopting SFAS No. 142, we recorded the following non-cash pre-tax charges of $565 million ($410 million after-tax):

- $536 million for the impairment provisions related to goodwill in our Animal Health business was included in the Pharmaceuticals segment - determined in the second quarter of 2002 and reported as a one-time cumulative effect of a change in accounting principle as of the beginning of 2002.
- $29 million for the impairment provisions related to identifiable intangible assets was included in the Consumer Products segment ($25 million) and the Pharmaceuticals segment ($4 million) - determined in the first quarter of 2002 and reported as a one-time cumulative effect of a change in accounting principle as of the beginning of 2002.

|*                           | As a result of adopting SFAS No. 142, we recorded a write-down of $536 million for the impairment provisions related to goodwill in our Animal Health business. The write-down was offset by the impact of foreign exchange. The fair value of the Animal Health business was determined using discounted cash flows.

Accounting for the Impairment or Disposal of Long-Lived Assets

On January 1, 2002, we adopted the provisions of SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. SFAS No. 144 requires that long-lived assets to be disposed of by sale, including those of discontinued operations, be measured at the lower of carrying amount or fair value less cost to sell, whether reported in continuing operations or in discontinued operations. Under these rules, discontinued operations will no longer be measured at net realizable value or include amounts for operating losses that have not yet been incurred. SFAS No. 144 also broadens the reporting of discontinued operations to include all components of an entity with operations that can be distinguished from the rest of the entity and that will be eliminated from the ongoing operations of the entity in a disposal transaction. The adoption of SFAS No. 144 has no impact on our current operations.

Accounting for Certain Vendor Consideration

The Emerging Issues Task Force (EITF) Issue No. 01-09, Accounting for Consideration Given by a Vendor to a Customer,codified and reconciled the following EITF Issues:

- Issue No. 00-14, Accounting for Certain Sales Incentives
- Issue No. 00-22, Accounting for Points and Certain Other Time-Based or Volume-Based Sales Incentive Offers and Offers for Free Products or Services to be Delivered in the Future
- Issue No. 00-25, Vendor Income Statement Characterization of Consideration Paid to a Reseller of the Vendor's Products

In 2001, we adopted the provisions of EITF Issues No. 00-14 and 00-22 and on January 1, 2002, we adopted the provisions of EITF Issue No. 00-25. EITF Issue No. 00-25 requires the cost of certain vendor consideration to be classified as a reduction of revenue rather than as a marketing expense. We restated our quarterly and full year 2001 statement of income to reflect the reclassification of the cost of certain vendor consideration from Selling, informational and administrative expensesto a reduction in Revenues.These reclassifications have no effect on net income.

The costs of certain marketing expenses reclassified from Selling, informational and administrative expenses to a reduction in Revenues in the quarterly and full year 2001 condensed consolidated statements of income follow:

Note 4:  Financial Instruments

A.  Investments in Debt and Equity Securities

In the second quarter of 2002, we reclassified substantially all of our held-to-maturity debt securities to available-for-sale debt securities. The amortized cost of the securities reclassified was $13,839 million and the unrealized gain on such securities was immaterial. We review the salient characteristics of our debt securities portfolio on at least a quarterly basis. Upon completion of this review, we reclassified the securities because we no longer have the positive intent to hold such securities to maturity. As a result of this decision, any debt security that we may purchase over a two year period, which began July 1, 2002, will not be classified as held-to-maturity.

Information about our investments follow:

B.  Derivative Financial Instruments and Hedging Activities

During the first nine months of 2002, we entered into the following new or incremental derivative and hedging activities:

Foreign Exchange Risk

These foreign exchange financial instruments serve to protect net income against the impact of the translation into U.S. dollars of certain foreign exchange denominated transactions.

- $2,298 million notional amount of foreign currency forward-exchange contracts are designated as cash flow hedges of euro-denominated available-for-sale investments maturing through the fourth quarter of 2002. These contracts fix the exchange rate between euros and U.S. dollars related to both the principal and interest on the investments.
- $631 million notional amount of foreign currency swaps are designated as cash flow hedges of a U.K. pound intercompany loan maturing in late 2006. These swaps fix the exchange rate between U.K. pounds and U.S. dollars related to both the principal and interest on the loan.
- $615 million notional amount of Japanese yen put options are designated as cash flow hedges to partially hedge the U.S. dollar/Japanese yen exchange rate related to forecasted intercompany inventory purchases through 2003. These options fix the exchange rate between Japanese yen and the U.S. dollar and are reported in Prepaid expenses and taxesandAccumulated other comprehensive expense. Gains or losses on such options are recognized in Cost of saleswhen the related inventory is sold to third-party customers.
- $313 million increment 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 related to foreign exchange.
- $202 million notional amount of foreign currency swaps are designated as cash flow hedges of a Japanese yen intercompany loan maturing in the first quarter of 2003. These swaps fix the exchange rate between Japanese yen and Canadian dollars related to both the principal and interest on the loan.

Interest Rate Risk

- $985 million notional amount of yen forward-starting interest rate swaps maturing in late 2006 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 .9%. These forward-starting swaps will effectively replace existing yen interest rate swaps with the same notional amount when the existing swaps mature in 2003.
- $600 million notional amount of interest rate swaps maturing in 2009 are designated as fair value hedges of the changes in the fair value of fixed rate debt. These swaps serve to reduce our exposure to long-term U.S. dollar interest rates by effectively converting the fixed rates associated with the long-term debt to floating rates.
- $410 million notional amount of U.S. dollar interest rate swaps maturing in early 2007 are designated as cash flow hedges of "LIBOR" interest rates related to forecasted purchases of short-term fixed rate debt investments to be classified as available-for-sale securities. These swaps serve to reduce the variability of LIBOR interest rates by effectively fixing the rates on short-term debt securities at 5%.
- $171 million notional amount of yen interest rate swaps maturing in early 2009 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 1.1%.
- $142 million notional amount of yen interest rate swaps maturing in early 2006 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 .5%.

There was no material ineffectiveness in any hedging relationship reported in earnings in the first nine months of 2002.

|*Included in Other current liabilities.

Through September 29, 2002, the charges for employee termination costs represent the approved reduction of our work force by 7,611 people, mainly comprising administrative functions for corporate, manufacturing, distribution, sales and research. We notified these people and as of September 29, 2002, 7,394 employees were terminated. We will complete terminations of the remaining personnel by September 29, 2003. 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. Severance benefits deferred for future payments were $218 million at September 29, 2002 and $215 million at December 31, 2001. The deferred severance benefits are considered utilized charges and are included in Other noncurrent liabilitiesin the condensed balance sheet.

The impairment and disposal charges through September 29, 2002 for property, plant and equipment in the above table include the consolidation of facilities and related fixed assets, a contract termination payment and termination of certain software installation projects. Other restructuring charges in the nine months ended September 29, 2002 consist of charges for contract termination payments-$6 million ($2 million in the third quarter ended September  29, 2002); facility closure costs-$4 million ($2 million in the third quarter ended September 29, 2002) and assets we wrote off, including inventory and intangible assets-$1 million (none in the third quarter ended September 29, 2002). Since inception of the merger, other restructuring charges consist of charges for contract termination payments-$49 million; facility closure costs-$10 million and assets we wrote off, including inventory and intangible assets-$7 million.

Stock options and stock issuable under employee compensation plans representing equivalents of 297 million shares of common stock during the three months ended September 29, 2002, 204 million shares of common stock during the nine months ended September 29, 2002 and 137 million shares of common stock during the three months and nine months ended September 30, 2001 had exercise prices greater than the average market price of our common stock. These common stock equivalents were outstanding during the three months and nine months ended September 29, 2002 and September 30, 2001 but were excluded from the computation of diluted earnings per common share for those periods because their inclusion would have had an antidilutive effect.

Note 10:  Defined Contribution Plans

We have savings and investment plans in several countries including the U.S. and Puerto Rico. Employees may contribute a portion of their salaries to the plans and we match, in company stock, a portion of the employee contributions. The contribution and match for U.S. participants is held in an Employee Stock Ownership Plan that was adopted on February 1, 2002.

Note 11:  Proposed Acquisition of Pharmacia Corporation

On July 15, 2002, we announced that we signed a definitive agreement to merge with Pharmacia Corporation (Pharmacia) in a stock-for-stock transaction valued on that date at approximately $60 billion. Under terms of the merger agreement, which has been approved by the boards of directors of both Pfizer and Pharmacia, after the spin-off by Pharmacia of Monsanto Inc., its agricultural products division, (which occurred on August 13, 2002), upon close of the transaction we will exchange 1.4 shares of Pfizer common stock for each outstanding share of Pharmacia common stock in a tax-free transaction resulting in the issuance of approximately 2 billion shares of Pfizer common stock. We also will exchange 1.4 options on Pfizer common stock for each outstanding Pharmacia option at the merger date. In addition, each share of Pharmacia convertible perpetual preferred stock will be exchanged for a newly created class of Pfizer convertible perpetual preferred stock with rights substantially identical to the rights of the Pharmacia convertible perpetual preferred stock. The close of the transaction is subject to shareholder approval at both companies, governmental and regulatory approvals and other usual and customary closing conditions. We are targeting closing the transaction by year-end 2002; however, the final regulatory review process may result in the closing occurring early in the first quarter of 2003.

On October 21, 2002, the Securities and Exchange Commission (SEC) declared effective our Registration Statement on Form S-4 in connection with our proposed acquisition of Pharmacia. The Registration Statement includes a joint proxy statement/prospectus that has been sent to the shareholders of both companies. We have scheduled a Pfizer shareholder meeting on December 6, 2002 to vote to increase the number of authorized shares as well as to vote on the proposed acquisition. Pharmacia has announced a meeting for its shareholders to take place on December 9, 2002 to vote on the proposed acquisition.

Note 12:  Other Matters

On June 27, 2002, we announced that we are exploring strategic options for the Adams confectionery business and the Schick-Wilkinson Sword shaving products business, including possible sale of the businesses. Earlier in the year, we announced that we were exploring strategic options for the Tetra aquarium and pond supplies business, including possible sale of the business. On November 5, 2002, we entered into an agreement to sell the Tetra business for $238.5 million to The Triton Fund. The sale is subject to normal regulatory approvals and other closing conditions and is expected to close by year-end.

On July 15, 2002, we announced an increase in the share-purchase program authorized by our board of directors on June 27, 2002 from $10 billion to $16 billion. We will buy back our common stock via open market purchases, as circumstances and prices warrant, with the anticipation of completing the share-purchase program in 2003. Under the current share-purchase program, we purchased approximately 93.4 million shares of common stock at an average price of $29.22 per share, at a total cost of approximately $2.73 billion. In May 2002, we completed the share-purchase program authorized in June 2001. In total, we purchased approximately 120 million shares at a total cost of $4.8 billion under the June 2001 program. Purchased shares are available for general corporate purposes.

On October 24, 2002, our board of directors declared a $.13 per share fourth-quarter 2002 cash dividend on our common stock, payable December 5, 2002 to shareholders of record on November 15, 2002.

On November 12, 2002, the SEC declared effective our $5 billion debt shelf-registration statement.

INDEPENDENT ACCOUNTANTS' REVIEW 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 September 29, 2002 and the related condensed consolidated statements of income for the three-month and nine-month periods ended September 29, 2002 and September 30, 2001 and cash flows for the nine-month periods then ended. These condensed consolidated financial statements are the responsibility of the Company's management.

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 auditing standards generally accepted in the United States of America, 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 accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with auditing standards generally accepted in the United States of America, the consolidated balance sheet of Pfizer Inc. and Subsidiary Companies as of December 31, 2001, 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 28, 2002, 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, 2001, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

The revenue increase was primarily due to volume growth of our in-line products and newly launched products across major businesses and regions. Effective January 2, 2002 and July 1, 2002, we increased the published prices of certain of our human pharmaceutical products.

Changes in foreign exchange rates increased revenues in the third quarter of 2002 by $133 million or 1.7% and decreased revenues in the first nine months of 2002 by $144 million or 0.6%. The foreign exchange impact on the third quarter of 2002 revenue growth, relative to the same period last year, primarily reflects the recent weakening of the U.S. dollar relative to the Japanese yen, euro and British pound partially offset by devaluations in several Latin American markets.

In the second quarter of 2001, we brought the accounting methodology pertaining to accruals for estimated liabilities related to Medicaid discounts and contract rebates of Warner-Lambert into conformity with our historical method. We determine the amount of Medicaid discounts and contract rebates based on an estimate of reimbursable prescriptions filled for individuals covered by Medicaid or a provider with whom we contract. At Warner-Lambert, the amount of the liability was determined based on a historical percentage of sales. The adjustment reverses the cumulative effect of several years of applying different methodologies. The adjustment increased revenues in the first nine months of 2001 by $175 million.

The components of the revenue increase in the four quarters and year ended 2001 were as follows:

Aricept, discovered and developed by our alliance partner Eisai Co., Ltd., is the world's leading medicine for the treatment of symptoms of Alzheimer's disease.

Celebrex, a COX-2 specific inhibitor discovered and developed by our alliance partner Pharmacia Corporation (Pharmacia), is used for relief of the pain and inflammation of osteoarthritis (OA), adult rheumatoid arthritis (RA), acute pain and primary dysmenorrhea (menstrual pain) in adults. In addition, Celebrex is approved to reduce the number of adenomatous colorectal polyps in familial adenomatous polyposis, a rare genetic disease that may result in colorectal cancer, as an adjunct to usual care. With the approval for acute pain and primary dysmenorrhea in the U.S., Celebrex is the COX-2 specific inhibitor approved to treat the broadest range of conditions. In June 2002, the FDA approved revised labeling for Celebrex. The new prescribing information includes additional gastrointestinal safety data and data indicating that there was no increased risk for serious cardiovascular adverse events observed, including heart attack, stroke and unstable angina.

Bextra (valdecoxib), discovered and developed by our alliance partner Pharmacia, is used for relief of the pain and inflammation of OA, RA, and primary dysmenorrhea. Bextra was approved by the FDA in November 2001 and launched in the U.S. in April 2002. In July 2002, the regulatory authorities in Europe recommended Bextra for approval. Pfizer and Pharmacia are currently in discussions with the FDA regarding the receipt of some spontaneous adverse reports involving serious skin and hypersensitivity reactions among patients taking Bextra. Some of these cases have occurred in patients with a history of allergic-type reactions to sulfonamides. These reports were identified, reviewed, and reported through the companies' post-marketing pharmacovigilance program. A letter was sent to healthcare providers notifying them of the additional information regarding these adverse events. We are currently in discussions with the FDA regarding appropriate changes to the Bextra package insert.

Pharmacia's worldwide sales of Celebrex decreased 3% to $824 million in the third quarter of 2002 and increased 1% to $2,238 million in the first nine months of 2002. Pharmacia's worldwide sales for Bextra were $139 million in the third quarter of 2002 and $286 million in the first nine months of 2002.

Rebif, a treatment for multiple sclerosis (MS), was approved by the FDA and launched in the U.S. in March 2002.

On July 11, 2002, we announced an agreement with Serono, Inc. (Serono) to co-promote Serono's Rebif in the U.S. Rebif has been shown to decrease the frequency of severe symptoms and delay the accumulation of physical disability associated with relapsing forms of MS. In accordance with the terms of the agreement, on August 8, 2002, we paid Serono $200 million related to our co-promotion rights, which has been capitalized and will be amortized over the life of the agreement. We share all commercialization and development costs in the U.S. and receive payments based on Rebif sales in the U.S. Serono records all sales and continues to distribute the product worldwide, including the U.S. The product is sold under the Rebif brand name. Serono is the sole marketer for Rebif in the rest of the world.

Spiriva, discovered and developed by our alliance partner Boehringer Ingelheim, is used to treat chronic obstructive pulmonary disease. Spiriva completed mutual recognition in the European Union in April 2002 and has been launched in ten countries, including Germany and the United Kingdom.

Animal Health sales increased 10% to $280 million in the third quarter of 2002 (up 9% excluding the impact of foreign exchange) and increased 10% to $794 million in the first nine months of 2002 (up 13% excluding the impact of foreign exchange) as compared with the prior year periods. Sales of the major categories of Animal Health products in the third quarter and first nine months of 2002 were as follows:

|(in millions)             | Third Quarter |           | First Nine Months
|------------------------- | ------------- | --------- | -----------------

|                          |               |           |

|Total animal health       | $280
====     | $253
==== | 10               

- Revenue growth in the companion animal product lines of 17% in the third quarter of 2002 and 16% in the first nine months of 2002 was driven by strong global performance that was well balanced across key brands. This resulted in:
- an increase in sales of Rimadyl (for relief of arthritis pain in dogs) of 35% in the third quarter of 2002 and 22% in the first nine months of 2002, driven mostly by increased veterinary demand in the U.S. based on new FDA-approved post-operative pain indication.
- an increase in sales of Revolution/Stronghold (for protection against fleas and heartworm) of 25% in the third quarter of 2002 and 40% in the first nine months of 2002. This performance was largely due to the stabilization of product returns, the benefits generated from increased promotional efforts in Europe and a change from distributorship to direct customer sales in one of our Asian markets.
- an increase in sales of Clavamox/Synulox (an antibiotic for dogs and cats) of 21% in the third quarter and first nine months of 2002. The growth was due to increased brand emphasis and promotional efforts throughout our markets.
- Revenue growth in the livestock product lines of 4% in the third quarter of 2002 and 5% in the first nine months of 2002 reflects:
- an increase in livestock vaccines consisting of swine vaccine growth of 23% in the third quarter of 2002 and 16% in the first nine months of 2002. Growth was driven by the third quarter launch of Flusure (a swine influenza vaccine) in the U.S., as well as the launch of RespiSure One/Stellamune One (a single dose swine vaccine to prevent pneumonia) in our international markets.
- an increase in sales of cattle vaccines of 12% in the third quarter of 2002 and 15% in the first nine months of 2002 driven by growth in our European markets, where the livestock market has continued to show signs of recovery, and in Latin America resulting from higher sales of foot-and-mouth vaccines.

Consumer Products

Sales of the Consumer Products segment for the third quarter of 2002 increased 3% (remained flat excluding the impact of foreign exchange) and increased 4% in the first nine months of 2002 (up 6% excluding the impact of foreign exchange) as compared with the prior year periods. Worldwide sales of the Consumer Products segment follow:

Consumer Healthcare product sales increased 6% in the third quarter of 2002 (up 5% excluding the impact of foreign exchange) and increased 9% in the first nine months of 2002 (up 10% excluding the impact of foreign exchange), as compared with the prior year periods. These changes were mainly due to the sales growth of Listerine mouthwash which increased 13% in the third quarter of 2002 and 12% in the first nine months of 2002, and the success of Listerine PocketPaks which was introduced in the United States in September 2001. Worldwide revenue of Listerine PocketPaks was $44 million in the third quarter of 2002 and $162 million in the first nine months of 2002.

Sales of Confectionery products in the third quarter of 2002 remained unchanged at $457 million (up 4% excluding the impact of foreign exchange) and decreased 1% in the first nine months of 2002 (up 2% excluding the impact of foreign exchange), as compared with the prior year periods. These changes were mainly due to strong sales of Trident gums and other dental care products, which increased 14% in the third quarter of 2002 and 8% in the first nine months of 2002, partially offset by sales declines of Halls cough drops, which decreased 7% in the third quarter and first nine months of 2002.

We announced that we are exploring strategic options for the Adams confectionery business, the Schick-Wilkinson Sword shaving products business and the Tetra aquarium and pond supplies business, including possible sale of the businesses. On November 5, 2002, we entered into an agreement to sell the Tetra aquarium and pond supplies business for $238.5 million to The Triton Fund. The sale is subject to normal regulatory approvals and other closing conditions and is expected to close by year-end.

The loss of patent protection with respect to any of our major products, including those described in the Legal Proceedings section, would have an effect on our projected revenues and net income.

COSTS AND EXPENSES

Cost of Sales

Cost of sales increased 12% in the third quarter of 2002 and 5% in the first nine months of 2002 as compared with the prior year periods, while revenues increased 12% in the third quarter of 2002 and 9% in the first nine months of 2002. The growth in cost of sales in the third quarter of 2002 was substantially higher than the growth through the first nine months due to the negative impact of foreign exchange. Excluding the impact of foreign exchange, cost of sales growth was only 1% in the third quarter of 2002. Revenue growth of 9% outpaced cost of sales growth of 5% on a year-to-date basis due to favorable business and product mix, the benefit of integration synergies, and improvements in manufacturing efficiencies. Manufacturing efficiencies stem from greater volume and cost reductions attributable to procurement initiatives and plant operating efficiencies.

Selling, Informational and Administrative Expenses

Selling, informational and administrative (SI&A) expenses increased 13% in the third quarter of 2002 and increased 11% in the first nine months of 2002 as compared with the prior year periods mainly due to strong marketing and sales support for our broad portfolio of human pharmaceutical products. Human pharmaceutical marketing expenses increased by 10% in the third quarter of 2002 and 12% in the first nine months of 2002 as compared with the prior year periods. During 2002, marketing expenses included costs associated with the second quarter U.S. launch of our new anti-arthritic product Bextra, co-promoted with Pharmacia, third quarter U.S. launch of our novel antifungal agent Vfend, and initial commercial support in the third quarter of the multiple sclerosis product Rebif, co-promoted in the U.S. with Serono.

Research and Development Expenses

Research and development (R&D) expenses increased 6% in the third quarter of 2002 and 12% in the first nine months of 2002 as compared with the prior year periods. Year over year growth for R&D spending for the third quarter and first nine months of 2002, as compared with the prior year periods, is attributable to increased support of the late-stage portfolio, higher costs as a result of the recent expansion of facilities and increased information technology costs due to the continued implementation of enterprise-wide resource management systems.

We continue to invest in R&D to provide future sources of revenue through the development of new products, as well as through additional uses for existing in-line and alliance products. Currently, we have six new products that were recently approved or are undergoing regulatory review in the U.S. and/or European Union (E.U.):

- Bextra (discovered and developed by Pharmacia Corporation) for relief of the pain and inflammation of osteoarthritis and adult rheumatoid arthritis, and primary dysmenorrhea, was made available in the U.S. in February 2002 in an early experience program, and was launched in April 2002. Bextra was filed in the E.U. in June 2001. Bextra was recommended for approval by the regulatory authorities in Europe in July 2002.
- Spiriva (discovered and developed by Boehringer Ingelheim), for chronic obstructive pulmonary disease (COPD), completed mutual recognition in the E.U. in April 2002. Spiriva has now been launched in ten countries, including Germany and the U.K. Spiriva was filed in the U.S. with the FDA in December 2001. In September 2002, an advisory committee to the FDA recommended that Spiriva be approved for the long-term, once-daily maintenance treatment of bronchospasm associated with COPD.
- Vfend, a new antifungal, was approved in both oral and intravenous forms in the U.S. by the FDA in May 2002 and in the E.U. in March 2002. Vfend was launched in July 2002 in the U.S. and in Europe in September 2002.
- Geodon, a new antipsychotic, was launched in the U.S. in the first quarter of 2001. In June 2002, the FDA approved the IM form of Geodon making it the first new generation (atypical antipsychotic) medicine for schizophrenia approved in the U.S. for IM use. Geodon IM was launched in the U.S. in September 2002. Geodon has also been launched in Sweden, Germany and 21 other countries. Launches of both the oral and IM form of Geodon will continue to occur in 15 countries throughout 2002 and 2003.
- Relpax, a treatment for migraine headaches, completed mutual recognition and approval in the E.U. in July 2001 and has been launched in the U.K., Italy, Japan and other markets. In April 2002, we received marketing approval for Relpax in Japan and launched the product in July 2002. In the U.S., we recently completed a cardiovascular physiology safety study requested by the FDA in their approvable letter of December 2000. We analyzed the data and submitted the results to the FDA in June 2002. We anticipate FDA approval by year end 2002 and U.S. launch soon thereafter.
- Rebif, which we co-promote with Serono in the U.S., has been shown to decrease the frequency of severe symptoms and delay the accumulation of physical disability associated with relapsing forms of multiple sclerosis. Rebif was approved by the FDA and launched in the U.S. in March 2002.

We expect to launch all six products in new markets once regulatory approval is received. However, there are no assurances as to when, or if, we will receive regulatory approval for these or any of our new products.

In the first nine months of 2002, we submitted the following new indications/dosage forms to the FDA:

It is our current intention to submit applications for the following new chemical compounds subject to ongoing negotiations and discussions with various regulatory agencies:

- darifenacin in 2002 for the treatment of overactive bladder
- pregabalin in 2003 for the treatment of neuropathic pain, epilepsy, and generalized anxiety disorder
- Lipitor/Norvasc dual therapy in early 2003 and make it available to patients by 2004

Advanced-stage clinical studies are continuing for several agents, including capravirine for HIV/AIDS, lasofoxifene for osteoporosis and other indications, and Exubera, an inhalable form of insulin under co-development, co-manufacture, and co-marketing with Aventis Pharma (Aventis), with the participation of Inhale Therapeutic Systems.

Together with Aventis, we will complete additional long-term studies for the Exubera development program. These trials are well under way and involve patients with Type 1 and Type 2 diabetes. Because of the potential widespread use of Exubera among diabetes patients, additional rigorous testing and assessment of all pulmonary function measures are appropriate to deepen the medical understanding of diabetes and Exubera's role in the future management of diabetes. Based on interim data from one-year controlled safety studies, we are confident that Exubera will be an important medication to treat this devastating disease. We are continuing our discussions with regulatory agencies regarding the timing of the submission.

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

Merger-Related Synergies

The growth rates of cost of sales, SI&A expenses and R&D expenses were reduced for the quarter and the year due to greater synergies related to the acquisition of Warner-Lambert. Merger-related synergies of about $440 million were achieved in the third quarter of 2002 versus about $360 million in the prior year period. Merger-related synergies of about $1.3 billion were achieved in the first nine months of 2002 versus about $1.0 billion in the prior year period.

MERGER-RELATED COSTS

We incurred the following merger-related costs in connection with our merger with Warner-Lambert which was completed on June 19, 2000:

|*Included in Other current liabilities.

Through September 29, 2002, the charges for employee termination costs represent the approved reduction of our work force by 7,611 people, mainly comprising administrative functions for corporate, manufacturing, distribution, sales and research. We notified these people and as of September 29, 2002, 7,394 employees were terminated. We will complete terminations of the remaining personnel by September 29, 2003. 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. Severance benefits deferred for future payments were $218 million at September 29, 2002 and $215 million at December 31, 2001. The deferred severance benefits are considered utilized charges and are included in Other noncurrent liabilitiesin the condensed balance sheet.

The impairment and disposal charges through September 29, 2002 for property, plant and equipment in the above table include the consolidation of facilities and related fixed assets, a contract termination payment and termination of certain software installation projects. Other restructuring charges in the nine months ended September 29, 2002 consist of charges for contract termination payments-$6 million ($2 million in the third quarter ended September 29, 2002); facility closure costs-$4 million ($2 million in the third quarter ended September 29, 2002) and assets we wrote off, including inventory and intangible assets-$1 million (none in the third quarter ended September 29, 2002). Since inception of the merger, other restructuring charges consist of charges for contract termination payments-$49 million; facility closure costs-$10 million and assets we wrote off, including inventory and intangible assets-$7 million.

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

We anticipate total merger-related costs through 2002, excluding the transaction costs of approximately $1.8 billion related to Warner-Lambert's termination of the Warner-Lambert/American Home Products merger agreement, of about $2.8 billion.

Interest income in the third quarter and first nine months of 2002 decreased over the prior year periods as a result of significantly lower short-term interest rates, partially offset by increased levels of investments. Interest expense in the third quarter of 2002 increased over the prior year period as a result of higher average levels of borrowings in 2002 related primarily to the share-purchase program. The lower interest expense in the first nine months of 2002 reflects lower average interest rates, partially offset by higher average levels of borrowings. Amortization of goodwill and other intangibles decreased in the third quarter and first nine months of 2002 over the prior year periods largely as a result of the adoption of SFAS No. 142, Goodwill and Other Intangible Assets.Amortization of other intangibles is also recorded in Cost of sales and Research and development expenses in the condensed consolidated statement of income.

TAXES ON INCOME

Our projected tax rate for continuing operations in 2002 is 22.9%. Our projected tax rate of 23.5% for continuing operations in 2002, excluding the cumulative effect of a change in accounting principle, certain significant items and merger-related costs has been reduced from the first quarter 2002 estimate of 25.0%. This rate reduction is due primarily to changes in product mix and tax-planning initiatives.

INCOME FROM CONTINUING OPERATIONS

Income from continuing operations, excluding certain significant items and merger-related costs, increased 12% in the third quarter of 2002. Income from continuing operations, excluding the cumulative effect of a change in accounting principle, certain significant items and merger-related costs, increased 12% in the first nine months of 2002. A reconciliation between reported income from continuing operations before cumulative effect of a change in accounting principle and income from continuing operations excluding the cumulative effect of a change in accounting principle, certain significant items and merger-related costs follows:

* Wherever possible, cash management is centralized and intercompany financing is used to provide working capital to countries as needed. Where local restrictions prevent intercompany financing, then cash balances would remain in the country and local needs would be met through ongoing cash flows and/or external borrowings.

**We rely on operating cash flow, short-term commercial paper borrowings and long-term debt to provide for working capital needs.

***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, 2001 to September 29, 2002 primarily reflects:

- cash from current period operations and long-term debt issuances

partially offset by:

- purchases of property, plant and equipment ($1,259 million)
- purchases of our common stock ($4,726 million)
- cash dividends on common stock ($2,382 million)

The increase in shareholders' equity per common share is primarily due to net income in excess of dividends declared and/or paid.

Net Cash Provided by Operating Activities

During the first nine months of 2002, net cash provided by operating activities was $6,449 million, as compared to $6,817 million in the 2001 period. The change in net cash provided by operating activities in 2002 was primarily due to:

- an increase in accounts receivable (an increase of $833 million) due in part to efforts in 2001 to accelerate collections from certain of our customers
- an increase in inventories (an increase of $109 million)

partially offset by:

- an increase in operating income

Net Cash Used in Investing Activities

During the first nine months of 2002, investing activities used net cash of $3,754 million, as compared to $5,170 million in the 2001 period. The change in net cash used in investing activities in 2002 was primarily attributable to:

- fewer purchases of property, plant and equipment (a decrease of $260 million)
- more proceeds received from sales of investments (an increase of $4,163 million)

partially offset by:

- more purchases of investments and other assets (an increase of $3,080 million)

Net Cash Used in Financing Activities

During the first nine months of 2002, net cash used in financing activities was $1,955 million, as compared to $814 million in the 2001 period. The change in net cash used in financing activities in 2002 was primarily attributable to:

- an increase in common share purchases (an increase of $2,513 million)
- an increase in cash dividends paid (an increase of $344 million)

partially offset by:

- an increase in net borrowings (an increase of $1,686 million)

In April 2002, we issued $600 million of senior unsubordinated dollar-denominated debt. The notes mature on April 15, 2009 with interest payable annually, in arrears, beginning on April 15, 2003 at a rate of 5.625%.

In July 2002, we announced an increase in the share-purchase program authorized by our board of directors on June 27, 2002 from $10 billion to $16 billion. We will buy back our common stock via open market purchases, as circumstances and prices warrant, with the anticipation of completing the share-purchase program in 2003. Under the current share-purchase program, we purchased approximately 93.4 million shares of common stock at an average price of $29.22 per share, at a total cost of approximately $2.73 billion, during the third quarter of 2002. In May 2002, we completed the share-purchase program authorized in June 2001. In total, we purchased approximately 120 million shares at a total cost of $4.8 billion under the June 2001 program. In the first nine months, under both the 2002 and 2001 programs, we purchased approximately 145 million shares of common stock at a total cost of $4,726 million. Purchased shares are available for general corporate purposes.

On November 12, 2002, the Securities and Exchange Commission (SEC) declared effective our $5 billion debt shelf-registration statement.

Proposed Acquisition

On July 15, 2002, we announced that we signed a definitive agreement to merge with Pharmacia Corporation (Pharmacia) in a stock-for-stock transaction valued on that date at approximately $60 billion. Under terms of the merger agreement, which has been approved by the boards of directors of both Pfizer and Pharmacia, after the spin-off by Pharmacia of Monsanto Inc., its agricultural products division, (which occurred on August 13, 2002), upon close of the transaction we will exchange 1.4 shares of Pfizer common stock for each outstanding share of Pharmacia common stock in a tax-free transaction resulting in the issuance of approximately 2 billion shares of Pfizer common stock. We also will exchange 1.4 options on Pfizer common stock for each outstanding Pharmacia option at the merger date. In addition, each share of Pharmacia convertible perpetual preferred stock will be exchanged for a newly created class of Pfizer convertible perpetual preferred stock with rights substantially identical to the rights of the Pharmacia convertible perpetual preferred stock. The close of the transaction is subject to shareholder approval at both companies, governmental and regulatory approvals and other usual and customary closing conditions. We are targeting closing the transaction by year-end 2002; however, the final regulatory review process may result in the closing occurring early in the first quarter of 2003.

On October 21, 2002, the SEC declared effective our Registration Statement on Form S-4 in connection with our proposed acquisition of Pharmacia. This Registration Statement includes a joint proxy statement/prospectus that has been sent to the shareholders of both companies. We have scheduled a Pfizer shareholder meeting on December 6, 2002 to vote to increase the number of authorized shares as well as to vote on the proposed acquisition. Pharmacia has announced a meeting for its shareholders to take place on December 9, 2002 to vote on the proposed acquisition.

Financial Risk Management - Interest Rate Risk

We entered into yen forward-starting interest rate swaps in the first quarter of 2002 to adjust interest-sensitive forecasted short-term borrowings from 2003 through late 2006.

OUTLOOK

We anticipate double-digit full-year 2002 revenue growth at current exchange rates, margin improvements, and continuing investments in product support and in R&D, which is expected to be about $5.2 billion for the year. We expect nine products to each contribute more than $1 billion in 2002 Pfizer revenues, including four with more than $2 billion, two with more than $3 billion and one with more than $7 billion. We expect merger-related cost savings from our merger with Warner-Lambert to be $1.8 billion for 2002.

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 loss of patent protection for our products
- trends toward managed care and health care cost containment
- possible U.S. legislation affecting pharmaceutical pricing and reimbursement, including Medicaid and Medicare
- contingencies related to actual or alleged environmental contamination
- legal defense costs, insurance expense, settlement costs and the risk of an adverse decision related to product liability, patent protection and other lawsuits
- our company's ability to protect its patents and other 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
- changes in business, political and economic conditions due to the threat of future terrorist activity in the U.S. and other parts of the world, and related U.S. military action overseas
- growth in costs and expenses
- changes in our product mix
- the impact of acquisitions, divestitures, restructurings, product withdrawals and other unusual items, including our ability to obtain the anticipated results and synergies from our announced proposed acquisition of Pharmacia and the increased uncertainty created by the integration of the two businesses, as well as our proposed sale of the Tetra business and the timing and success of the announced exploration of strategic options for the Adams and Schick-Wilkinson Sword businesses, including the possible sale of such businesses

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 past results and 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 Forms 10-Q, 8-K and 10-K reports to the Securities and Exchange Commission. Our Form 10-K filing for the 2001 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.

Recently Issued Accounting Standard

In July 2002, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards (SFAS) No. 146 "Accounting for Costs Associated with Exit or Disposal Activities." SFAS No. 146 amends existing accounting rules for these costs by requiring that a liability be recorded at fair value when incurred. The liability would be reviewed regularly for changes in fair value with adjustments recorded in the consolidated financial statements. SFAS No. 146 also provides specific guidance for lease termination costs and one-time employee termination benefits when incurred as part of an exit or disposal activity. We have not determined the impact, if any, on our consolidated financial statements of adopting the provisions of SFAS No. 146. We expect to adopt the provisions of SFAS No. 146 on January 1, 2003.

Item 4.  Disclosure Controls and Procedures

Within 90 days prior to the date of this report, we carried out an evaluation, under the supervision and with the participation of our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures are effective in timely alerting them to material information required to be disclosed in our periodic reports filed with the SEC. It should be noted that the design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

In addition, we reviewed our internal controls, and there have been no significant changes in our internal controls or in other factors that could significantly affect those controls subsequent to the date of their last evaluation.

FORM 10-Q

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

A description of the legal proceedings in which we are involved, both in general and with respect to certain specific matters and types of matters, is contained in our Reports on Form 10-K for 2001 and on Form 10-Q for the first quarter of 2002, as amended, and Form 10-Q for the second quarter of 2002. The following is limited to an update on significant developments in previously reported matters as well as descriptions of certain new matters and should be read with reference to those earlier Reports. Unless specifically indicated, all previously reported matters remain pending.

Patent Litigation

We are involved in a number of patent suits, the majority of which involve claims by generic drug manufacturers that patents covering our products, processes or dosage forms are invalid and/or do not cover the product of the generic manufacturer. Pending suits include challenges to patents covering, among other products, gabapentin (Neurontin), fluconazole (Diflucan), amlodipine (Norvasc), quinapril (Accupril), glipizide (Glucotrol XL), nifedipine (Procardia XL), Estrostep Fe (oral contraceptive) and Femhrt 1/5 (hormone replacement therapy). There can be no assurances as to the outcome of any of these matters and a loss in any of these cases could result in a loss of patent protection for the drug at issue, which could lead to significant loss of sales of that drug in the U.S. market and could materially affect future results.

Norvasc

As previously reported, a generic manufacturer has filed an application with the FDA seeking approval to market amlodipine maleate, a different salt form from amlodipine besylate, which is employed in our approved product, Norvasc. The basic patent for Norvasc received an extension of term under the Hatch-Waxman Act to compensate for regulatory delays in approving the product. The generic manufacturer asserts that during the period of extension the exclusionary rights of the patent are restricted to amlodipine besylate and that after the original expiration date, February 2003, sales of amlodipine maleate would not infringe. We filed a patent infringement suit in the U. S. District Court for the District of New Jersey. The defendant has moved to dismiss the complaint. A second generic manufacturer has filed an abbreviated new drug application seeking to market amlodipine besylate, asserting the invalidity of our amlodipine patents. We also filed a patent infringement suit against this generic manufacturer in the U.S. District Court for the District of New Jersey in October 2002.

Neurontin

In the previously reported patent infringement litigation in the U. S. District Court for the District of New Jersey against generic manufacturers that filed abbreviated new drug applications asserting the invalidity and non-infringement of our gabapentin low-lactam patent, the generic manufacturers' motions to shorten the statutory 30-month stay period were denied. The defendants have filed further summary judgment motions, to which our responses are due in January 2003. The previously reported antitrust suits and counterclaims against us alleging antitrust violations in connection with our attempts to enforce our gabapentin patents have been consolidated in the same court and stayed pending the outcome of the underlying patent litigation.

Zoloft

Two generic manufacturers have each filed applications with the FDA seeking to market sertraline (Zoloft) and notified us that they are not seeking an effective date of approval until after the June 2006 expiration of the basic drug substance patent and pediatric exclusivity period. The manufacturers' applications to the FDA include challenges to later-expiring patents covering therapeutic uses and/or crystal forms of sertraline.

Lipitor

A generic manufacturer has filed an application with the FDA seeking to market atorvastatin (Lipitor) and notified us that it is not seeking an effective date of approval until after the June 2011 expiration of the patent covering the drug substance. The manufacturer's application to the FDA includes challenges to later-expiring patents covering formulations and crystal forms of atorvastatin.

Products Liability Litigation

Rezulin

As of October 31, 2002, suits filed in state and federal courts involved approximately 7,868 Rezulin users and approximately 1,088 users had asserted unfiled claims. In addition, we have agreed with certain plaintiffs' lawyers to extend the statute of limitations for approximately 30,345 people who do not have lawsuits on file and who may or may not eventually pursue claims.

On September 12, the U. S. District Court for the Southern District of New York, which is overseeing the Multidistrict proceedings, including the consolidated federal class actions, denied the plaintiffs' motion to certify a class of allegedly injured Rezulin users seeking money damages and a subclass of uninjured users seeking medical monitoring and damages for alleged consumer fraud or restitution of amounts they paid for Rezulin.

Twenty-three purported state class actions remain pending.

One of our insurance carriers that provides the first layer of excess coverage for these claims has sent us a letter denying coverage in connection with the Rezulin cases. We and our counsel believe that the carrier's position is without merit. If we are unable to resolve the matter satisfactorily with the carrier, we intend to initiate an arbitration proceeding to resolve the dispute and we would expect to prevail.

Asbestos

As of October 31, 2002, approximately 117,957 claims naming Pfizer and/or Quigley, as well as numerous other defendants, were pending in state and federal courts seeking damages for alleged asbestos exposures. Approximately 77,680 multi-defendant claims named American Optical, a former subsidiary of Warner-Lambert, alleging asbestos and other exposures.

Other Matters

Average Wholesale Price Litigation

On September 10, 2002, we were named as a defendant in a purported consolidated class action that had been previously pending in a Multidistrict proceeding in the U. S. District Court for the District of Massachusetts. The amended complaint alleges that Pfizer and other pharmaceutical manufacturers defrauded the plaintiff health care insurers and payors by selling certain products at prices lower than the published "average wholesale price" (AWP) at which the products were reimbursed by the plaintiffs. We were also added as a defendant in a virtually identical suit in state court in Los Angeles under California's unfair competition laws. Pretrial proceedings are at an early stage in both cases. Because we do not employ AWP in marketing our products, we believe both complaints are without merit.

South Africa

On October 23, 2002, we were served with a complaint in the U. S. District Court for the Southern District of New York on behalf of various purported classes and subclasses of current and former residents of South Africa, or their survivors, who allege that the defendants-83 foreign and domestic corporations-injured the plaintiffs by supporting and profiting from the Apartheid regime in South Africa during the period 1948-94. Claims are based on the Alien Tort Claims Act, the Torture Protection Act, RICO, and a variety of other international laws and treaties relating to violations of human rights, war crimes, and crimes against humanity. The complaint seeks, among other things, an accounting, the creation of a historic commission, compensatory damages in excess of $200 billion, punitive damages in excess of $200 billion, costs, and attorneys' fees. We believe the action is without merit.

Lipitor

As previously reported, the Department of Justice commenced a civil investigation into pricing for Lipitor during 1998 through 2001, aimed at determining whether grants and other payments made to certain health plans and pharmacy benefit managers should be characterized as rebates, which would entitle the government to a further discount under the Medicaid best-price rules. The investigation originated with a qui tam (private False Claims Act) lawsuit filed by a former Warner-Lambert employee. Pfizer has entered into an agreement to settle allegations relating to two grants made by Warner-Lambert to the Ochsner Health Plan in 1999 for $49 million, for which a reserve had previously been taken. With respect to additional allegations of payments to pharmacy benefit managers and other health plans, both Pfizer and the government have investigated and found the allegations not substantiated. The government thus has declined to intervene in the qui tam case with respect to these allegations but the private plaintiff is free to pursue them. In addition to the settlement, Pfizer has entered into a Corporate Integrity Agreement (CIA) with the Department of Health and Human Services's Office of Inspector General. The CIA enhances elements of Pfizer's existing health care law compliance program. Because a portion of the settlement is allocated to the states under the Medicaid rebate law, Pfizer is negotiating agreements with the states that will allow the funds to be released to them.

Neurontin

The U. S. Attorney's office in Boston, Massachusetts, has been conducting an investigation into Warner-Lambert's promotion of Neurontin. The investigation originated with a qui tam lawsuit filed by a former Warner-Lambert employee, alleging that Warner-Lambert violated the Federal False Claims Act based on certain sales and marketing practices concerning Neurontin. It is possible that criminal charges and fines could result from this investigation. We continue to cooperate with the inquiry. The allegations are also under review by a coalition of state attorneys general.

Tax Matters

The Internal Revenue Service (IRS) has completed and closed its audits of Pfizer Inc.'s tax returns through 1998 and Warner-Lambert Company through 1995. The IRS is currently conducting audits of Pfizer Inc.'s tax returns for the years 1999 and 2000 and Warner-Lambert Company for the years 1996 through 1998.

In November 1994, Belgian tax authorities notified Pfizer Research and Development Company NV/SA. ("PRDCO"), an indirect, wholly owned subsidiary of our company, of a proposed adjustment to the taxable income of PRDCO for fiscal year 1992. In January 1996, PRDCO received an assessment from the tax authorities for fiscal year 1993. On May 14, 2002, PRDCO reached an agreement with the Belgian authorities to settle this matter for an immaterial amount.

We believe that our accrual for tax liabilities are adequate for the relevant periods.
