Calculation of Certain Estimates

All financial information relating to Activision, Vivendi Games and Blizzard Entertainment included in these materials, including pro forma estimates for calendar year 2007, and projections for future periods, represent the companies’ respective estimates and projections and were not prepared in accordance with U.S. Generally Accepted Accounting Principles. These estimates exclude the impact of expenses related to equity-based compensation and related tax benefits, potential one-time restructuring charges of up to $100 million that may be incurred in connection with the transaction, and the potential impact from non-cash intangible amortization resulting from purchase price accounting. In addition, these estimates assume continued net revenue growth as well as expense reductions and other synergies that may or may not be realized. Estimates for future periods are subject to significant inherent uncertainties, which increase with periods farther into the future. Actual results may differ materially and are subject to risks, including the risks described in the Cautionary Note below. To the extent that the estimates for calendar year 2007 are based on the historical performance of Activision and Vivendi Games through September 30, 2007, not all such historical information has been audited, the accounting policies of the companies may differ, and the two companies have different fiscal years. The financial information for Blizzard Entertainment contained in these materials is presented on a stand-alone basis and does not reflect the results of operations of other Vivendi Games divisions.
