Bristol-Myers Squibb Sets Exchange Ratio of 0.6313 for the Exchange Offer

(NEW YORK, December 16, 2009)—Bristol-Myers Squibb Company (NYSE: BMY) and Mead Johnson Nutrition Company (NYSE: MJN) announced today that Bristol-Myers Squibb has set the exchange ratio for its offer to exchange up to 170.0 million shares of common stock of Mead Johnson for outstanding shares of Bristol-Myers Squibb common stock that are validly tendered and not validly withdrawn. The exchange ratio is 0.6313 shares of Mead Johnson common stock for each share of Bristol-Myers Squibb common stock accepted in the exchange offer.

The final calculated average Bristol-Myers Squibb price and the final calculated average Mead Johnson price, in each case determined in the manner described in the registration statement described below under “Additional Information,” would have resulted in an exchange ratio of more than the upper limit of 0.6313 shares of Mead Johnson common stock for each share of Bristol-Myers Squibb common stock. Accordingly, the upper limit is in effect.

The exchange offer will expire at 12 midnight, New York City time, on December 17, 2009, unless extended. The exchange offer is subject to customary closing conditions, including a minimum tender condition.

Based on the final exchange ratio, Bristol-Myers Squibb will accept for exchange a maximum of 269,285,601 shares of its common stock. The exchange offer will be subject to proration if it is over-subscribed, and, accordingly, the number of shares of Bristol-Myers Squibb common stock accepted in the exchange offer may be less than the number of shares of Bristol-Myers Squibb common stock tendered. If the exchange offer is consummated but not fully subscribed, Bristol-Myers Squibb intends to distribute any shares of Mead Johnson common stock it continues to own as a pro rata dividend to Bristol-Myers Squibb common stockholders.

Citigroup Global Markets Inc., Goldman, Sachs & Co. and Morgan Stanley & Co. Incorporated are serving as the dealer managers for the exchange offer.
