• In June 2006, we entered into a license agreement with Bayer Pharmaceuticals Corporation (Bayer) to acquire exclusive worldwide rights to DGAT-1 inhibitors, an innovative class of compounds that modify lipid metabolism. The lead compound in the class, BAY 74-4113, is a potential treatment for obesity, type 2 diabetes and other related disorders.

• In February 2006, we completed the acquisition of the sanofi- aventis worldwide rights, including patent rights and production technology, to manufacture and sell Exubera, an inhaled form of insulin for use in adults with type 1 and type 2 diabetes, and the insulin-production business and facilities located in Frankfurt, Germany, previously jointly owned by Pfizer and sanofi-aventis, for approximately $1.4 billion in cash (including transaction costs). In 2006, in connection with the acquisition, as part of our final purchase price allocation, we recorded $1.0 billion of developed technology rights, $218 million of inventory, and $166 million of Goodwill, all of which have been allocated to our Pharmaceutical segment. The amortization of the developed technology rights is primarily included in Cost of sales. Prior to the acquisition, in connection with our collaboration agreement with sanofi-aventis, we recorded a research and development milestone due to us from sanofi-aventis of $118 million ($71 million, after tax) in Research and development expenses upon the approval of Exubera in January 2006 by the FDA.

• In December 2006, we completed the acquisition of PowderMed Ltd.

(Rinat), a biologics company with several new central-nervous-system product candidates. In 2006, the aggregate cost of these and other smaller acquisitions was approximately $880 million (including transaction costs). In connection with these transactions, we recorded $835 million in Acquisition-related in- process research and development charges.

In 2006, we expensed a payment of $40 million, which was included in Research and development expenses. Additional milestone payments of up to $738 million could potentially be made to Incyte based upon the successful development and commercialization of products in multiple indications.
