        Pfizer Will Respond to FTC's Request for Additional Information

[The following message is based on an October 4 Pfizer news release]

Pfizer received an anticipated Request for Additional Information (Second
Request) from the Federal Trade Commission (FTC) on Thursday, October 3, the
company announced Friday, October 4. Pfizer is continuing to cooperate fully
with the FTC and, given the nature of the inquiries, we should be able to
address their questions promptly.

Pfizer also said that it continues to target regulatory approvals and closing of
the Pharmacia acquisition by year's end.

Since the Pharmacia acquisition was announced on July 15, Pfizer has made
significant progress in transition planning with more than 100 teams engaged in
the process across all business divisions and functions on a global basis. The
leadership of these teams includes both Pfizer and Pharmacia personnel. Pfizer
characterized the working relationship between the two companies during the
transition process as highly cooperative.

Pfizer has scheduled a shareholder meeting December 6 to discuss and vote on the
proposed acquisition. Pharmacia has announced a meeting for its shareholders to
take place December 9. Both meetings will be held in Wilmington, Delaware.

Certain statements contained in this document are "forward-looking statements"
provided under the "safe harbor" protection of the Private Securities Litigation
Reform Act of 1995. These statements are made to enable a better understanding
of the Company's business, but because these forward-looking statements are
subject to many risks, uncertainties, future developments and changes over time,
actual results may differ materially from those expressed or implied by such
forward-looking statements. Examples of forward-looking statements are
statements about anticipated financial or operating results, financial
projections, business prospects, future product performance, future research and

Company does not undertake any obligation to update any forward-looking
statements in any communications of the Company, whether as a result of new
information, future events, changed assumptions or otherwise, and all such
forward-looking statements should be read as of the time when the statements
were made, and with the recognition that these forward-looking statements may
not be complete or accurate at a later date.





Many factors may cause or contribute to actual results or events being
materially different from those expressed or implied by such forward-looking
statements. Although it is not possible to predict or identify all such factors,
they may include the following: competition for our products; pharmaceutical
pricing, price constraints and other restrictions on the marketing of products
imposed by governmental agencies or by managed care groups, institutions and
other purchasing agencies; product discovery and approval; product recalls or
withdrawals; manufacturing quality issues with respect to our products;
compliance with Current Good Manufacturing Practices and other quality assurance
guidelines; the company's ability to secure and defend its intellectual property
rights; product liability claims, antitrust litigation, environmental concerns,
and commercial disputes; social, legal, political and governmental developments;
changes in foreign currency exchange rates or in general economic or business
conditions including inflation and interest rates; acquisitions, divestitures,
mergers, restructurings or strategic initiatives that change the Company's
structure; business combinations among the Company's competitors and major
customers; changes to accounting standards or GAAP.
