Item 2.

Pursuant to existing agreements, the company had rights from Sanofi-Synthelabo,
Inc. (Sanofi) to manufacture, sell and market two products in North America:
AMBIEN and KERLONE. AMBIEN is a prescription medicine used in the treatment of
sleep disorders including insomnia. KERLONE, also a prescription medicine, is
used in the treatment of hypertension and cardiovascular disease. Sales of
AMBIEN and KERLONE, included in the company's results, were $902 million and
$5 million for the year ended December 31, 2001, respectively.

From inception of the agreements until December 31, 2001, Pharmacia recorded the
sales and expenses of the products and similarly recorded any related assets and
liabilities. At December 31, 2001, the company relinquished control over the
products to Sanofi and accordingly Pharmacia deconsolidated the related
operating assets and liabilities. Additionally, the company ceased recording
sales and expenses of AMBIEN and KERLONE as of January 1, 2002.

On April 16, 2002, Sanofi exercised its right to acquire all rights to the
products in North America in accordance with the agreements. In connection
with such acquisition, the company received a payment of $671 million for its
interest. The cash is reflected on the following pro forma consolidated balance
sheet, but the portion representing the gain on sale is not included in the pro
forma consolidated statement of earnings due to its nonrecurring nature. In the
second quarter of 2002, the company plans to record the gain resulting from this
payment under the caption of "All other, net" on the company's consolidated
statement of earnings.

The following pro forma consolidated balance sheet and pro forma consolidated
statement of earnings and the related explanatory notes reflect the impact of
this transaction on the company's reported results as of and for the year ended
December 31, 2001. The pro forma consolidated balance sheet reflects the
transaction as if it were consummated at December 31, 2001. Accordingly, the
adjustments to those balances give effect to all events that are directly
attributable to the transaction regardless of whether they have a continuing
impact or are nonrecurring. The pro forma consolidated statement of earnings
reflects the transaction as if it were consummated at January 1, 2001, the
beginning of the company's last fiscal year. All amounts of income and expense
that are expected to have a continuing impact on the company are reflected as
adjustments. Amounts that are not expected to have a continuing impact on the
company's results will not be adjusted. The notes that follow the pro forma
consolidated balance sheet and pro forma consolidated statement of earnings
provide further explanation of the adjustment amounts as appropriate.

The unaudited pro forma consolidated balance sheet and unaudited pro forma
consolidated statement of earnings and the related explanatory notes should be
read in conjunction with the historical consolidated financial statements and
notes thereto and other information included in Pharmacia's 2001 Annual Report
to Shareholders, which is incorporated by reference into Pharmacia's Annual
Report on Form 10-K for 2001. The unaudited pro forma information presented
below is for illustrative purposes only and is not necessarily indicative of the
results of operations or financial position that would have actually occurred if
the transaction had been consummated on the dates indicated or that may be
obtained in the future.

         NOTES TO UNAUDITED PRO FORMA CONSOLIDATED STATEMENT OF EARNINGS

A  - To adjust for net sales of AMBIEN of $902 and KERLONE of $5 for the year
     ended December 31, 2001.

B  - To adjust for cost of products sold of AMBIEN of $217 and $1 of KERLONE
     for the year ended December 31, 2001.

C  - To adjust for promotional expenses of $29 and distribution costs of $7
     for the year ended December 31, 2001.

D  - To adjust for net payments made to Sanofi for the year ended December 31,
     2001.

E  - Taxes have been estimated at 38 percent based on U.S. federal and state
     statutory rates for earnings from continuing operations associated with
     AMBIEN and KERLONE.

F  - As a result of adjusting the tax provision as described in Note E, the
     pro forma consolidated statement of earnings reflects an effective tax rate
     of approximately 11 percent. However, the company believes that








     this rate is not indicative of current operations and expects an effective
     rate of approximately 25 percent to be realized during the fiscal year
     ending 2002.

G  - Earnings from continuing operations per common share:

Basic earnings per share (EPS) is computed by dividing the earnings measure by
the weighted average number of shares of common stock outstanding. Diluted EPS
is computed assuming the exercise of stock options, conversion of preferred
stock and the issuance of stock as incentive compensation to certain employees.
Also in the diluted computations, earnings from continuing operations and net
earnings are reduced by an incremental contribution to the Employee Stock
Ownership Plan (ESOP). This contribution is the after-tax difference between the
income the ESOP would have received in preferred stock dividends and the
dividend on the common shares assumed to have been outstanding. The assumed
conversion of stock options having an exercise price higher than the weighted

reconciles the numerators and denominators of the basic and diluted earnings per
share computations.
