Pfizer to Acquire Pharmacia Corporation for $60 Billion in Stock

Pfizer and
Pharmacia jointly announced today that they have signed a definitive agreement
providing for Pfizer to acquire Pharmacia in a stock-for-stock transaction
valued at $60 billion, expanding the company's core strengths in pharmaceuticals
and health care. Pharmacia also announced that its Board of Directors intends to
proceed with its previously announced spin-off of its remaining 84 percent
ownership of Monsanto to its current shareholders. After the Monsanto spin-off,
Pfizer will exchange 1.4 shares of Pfizer common stock for each outstanding
share of Pharmacia stock in a tax-free transaction valued at $45.08 per
Pharmacia share, based on Pfizer's July 12 closing stock price of $32.20. This
transaction represents a 44 percent premium based on the average closing prices
of the two stocks over the last 30 days, adjusted for the Monsanto spin-off.

ownership of Monsanto stock to Pharmacia shareholders by means of a tax-free
dividend.
