                           FREQUENTLY ASKED QUESTIONS

Q. PFIZER RECENTLY ANNOUNCED PLANS TO ACQUIRE PHARMACIA. WHAT DOES THAT MEAN TO
ME AS A PHARMACIA SHAREHOLDER?
A. On July 15, 2002, Pfizer, Inc. and Pharmacia Corporation announced that they
had entered into an agreement by which Pharmacia is to be acquired by Pfizer in
a stock-for-stock transaction. Upon its completion, each Pharmacia Corporation
shareholder of record will receive 1.4 shares of Pfizer, Inc. common stock for
every one share of Pharmacia Corporation common stock held.

Q. WHEN WILL THE ACQUISITION OF PHARMACIA BY PFIZER BE COMPLETE?
A. Pfizer, Inc. expects the transaction to be complete in 4-6 months from July
15, 2002, the date of their announcement of their intent to acquire Pharmacia
Corporation subject to obtaining the necessary regulatory approvals.

Q. WHAT ARE THE TAX CONSEQUENCES OF THE PLANNED ACQUISITION BY PFIZER?
A. The Pfizer acquisition is planned to be a tax-free exchange in the U.S. of
Pharmacia shares for Pfizer shares. Each share of Pharmacia common stock will
convert into 1.4 shares of Pfizer, Inc. common stock.

Q. WHAT STEPS MUST BE COMPLETED FOR THE PFIZER TRANSACTION TO BE FINALIZED?
A. Among the key steps are regulatory filings with the SEC, antitrust filings
with the U.S. Federal Trade Commission (FTC) and Department of Justice (DOJ), EU
antitrust filings, and special shareholder meetings for shareholders of each
company.

Q. SINCE PHARMACIA IS TRADED ON THE NEW YORK STOCK EXCHANGE AND STOCKHOLM
EXCHANGE, WILL PFIZER LIST ITS SHARES IN SWEDEN?
A. Pfizer will determine whether or not to list its shares in Sweden at a later
date. Once that decision is made, more information will be provided to Swedish
shareholders on how to convert their Pharmacia shares.

Q. PLEASE EXPLAIN THE IPO FOR THE MONSANTO AGRICULTURAL BUSINESS AND THE
SUBSEQUENT DISTRIBUTION OF MONSANTO SHARES TO PHARMACIA SHAREHOLDERS OF RECORD.
A. On October 23, 2000, there was an initial public offering (IPO) of a portion
of the Monsanto agricultural business. At the completion of the IPO, Pharmacia
continued to own approximately 84% of Monsanto. Monsanto is represented on the
New York Stock Exchange by ticker symbol MON. No distributions of Monsanto stock
were made to Pharmacia Corporation shareholders of record at the time of the
initial public offering.

In November 2001, Pharmacia Corporation announced a plan to spin-off the
remaining 84% of Monsanto to Pharmacia shareholders by means of a tax-free
dividend. The Monsanto shares were distributed on August 13, 2002 to
shareholders of record on July 29, 2002.




Q. AS A RESULT OF THE SPIN-OFF OF THE REMAINING 84% OF THE AGRICULTURAL
BUSINESS, WHAT WERE PHARMACIA CORPORATION SHAREHOLDERS ENTITLED TO RECEIVE?
A. Pharmacia Corporation shareholders of record on July 29, 2002 were entitled
to receive 0.170593 shares of Monsanto stock for every one share of Pharmacia
stock. This ratio was obtained by dividing Pharmacia's total shares in Monsanto
(220,000,000) by the total number of shares outstanding in Pharmacia at 5:00 PM
Eastern time on July 29, 2002, which was 1,289,621,815.

Q. WILL THE ACQUISITION OF PHARMACIA CORPORATION BY PFIZER, INC. IMPACT THE
MONSANTO STOCK THAT I RECEIVED AS A RESULT OF THE AUGUST 13, 2002 SPIN-OFF?
A. No. With the completion of the spin-off, Monsanto is now a 100% wholly
independent company and Pfizer's acquisition of Pharmacia will not impact
holders of Monsanto stock.

SPIN-OFF.
