Important Information Calculation of Certain Estimates All financial information relating to Activision, Vivendi Games and Blizzard Entertainment included in this presentation, 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 this presentation is presented on a stand-alone basis and does not reflect the results of operations of other Vivendi Games divisions. Cautionary Note Regarding Forward-looking Statements Information in this presentation that involves expectations, plans, intentions or strategies regarding the future are forward-looking statements that are not facts and involve a number of risks and uncertainties.

Factors that could cause actual future results to differ materially from those expressed in the forward-looking statements set forth in this release include, but are not limited to, the timing and successful completion of the transactions described in this release (including the timing and receipt of stockholder and regulatory approvals and the satisfaction of other closing conditions), the combined companies’ success in executing planned strategies and achieving assumed synergies and cost savings, sales of each company’s titles, shifts in consumer spending trends, the seasonal and cyclical nature of the interactive game market, the ability of Activision Blizzard to predict consumer preferences among competing hardware platforms (including next-generation hardware), declines in software pricing, product returns and price protection, product delays, retail acceptance of the company’s products, adoption rate and availability of new hardware and related software, industry competition, rapid changes in technology and industry standards, protection of proprietary rights, maintenance of relationships with key personnel, customers, vendors and third-party developers, international economic and political conditions, integration of recent acquisitions and identification of suitable future acquisition opportunities, and foreign exchange rate changes. Other such factors include, without limitation, the additional risks identified in Activision's most recent annual report on Form 10-K and in the documents Vivendi has filed with the Autorité des Marchés Financiers (French securities regulator) and which are also available in English on Vivendi’s website (www.vivendi.com).
