of its non-standardized definition, Adjusted income (unlike U.S. GAAP Net income) may not be comparable with the calculation of similar measures for other companies. Adjusted income is presented solely to permit investors to more fully understand how management assesses our performance.

We also recognize that, as an internal measure of performance, the Adjusted income measure has limitations and we do not restrict our performance-management process solely to this metric. A limitation of the Adjusted income measure is that it provides a view of our operations without including all events during a period, such as the effects of an acquisition or amortization of purchased intangibles and does not provide a comparable view of our performance to other companies in the pharmaceutical industry. We also use other specifically tailored tools designed to ensure the highest levels of our performance. For example, our R&D organization has productivity targets, upon which its effectiveness is measured. In addition, Performance Share Awards grants made in 2006, 2007 and future years will be paid based on a non-discretionary formula that measures our performance using relative total shareholder return.

Purchase Accounting Adjustments

Adjusted income is calculated prior to considering certain significant purchase-accounting impacts, such as those related to our acquisitions of BioRexis, Embrex, Rinat, sanofi-aventis’ rights to Exubera, PowderMed, Idun and Vicuron, as well as net asset acquisitions. These impacts can include charges for purchased in-process R&D, the incremental charge to cost of sales from the sale of acquired inventory that was written up to fair value and the incremental charges related to the amortization of finite-lived

General Description of Adjusted Income Measure

Adjusted income is an alternative view of performance used by management and we believe that investors’ understanding of our performance is enhanced by disclosing this performance measure. We report Adjusted income in order to portray the results of our major operations—the discovery, development, manufacture, marketing and sale of prescription medicines for humans and animals—prior to considering certain income statement elements. We have defined Adjusted income as Net income before the impact of purchase accounting for acquisitions, acquisition-related costs, discontinued operations, the cumulative effect of a change in accounting principles and certain significant items. The Adjusted income measure is not, and should not be viewed as, a substitute for U.S. GAAP Net income.

intangible assets for the increase to fair value. Therefore, the Adjusted income measure includes the revenues earned upon the sale of the acquired products without considering the aforementioned significant charges.

Certain of the purchase-accounting adjustments associated with a business combination, such as the amortization of intangibles acquired in connection with our acquisition of Pharmacia in 2003, can occur for up to 40 years (these assets have a weighted-average useful life of approximately nine years), but this presentation provides an alternative view of our
