Section 3. Securities and Trading Markets Item 3.02 Unregistered Sales of Equity Securities. On January 3, 2006, CBS Corporation (the "Company") (formerly known as Viacom Inc. ("Old Viacom")) issued 8,978,359 shares of its Class B Common Stock, par value $0.001 per share ("CBS Class B Common Stock"), to trustees of rabbi trusts for certain of the Company's employee benefit plans. In consideration for the issuance of such CBS Class B Common Stock, the Company received an aggregate of 7,273,815 shares of class B common stock, par value $0.01 per share, of Old Viacom (the "Old Viacom Shares"). The shares issued on January 3, 2006 represented approximately 1.3% of the outstanding shares of CBS Class B Common Stock on that date. Such shares were issued in private placements which were exempt from registration pursuant to Section 4(2) of the Securities Act of 1933, as amended. The exemption from registration was based on, among other things, the number of former holders of Old Viacom Shares to receive such CBS Class B Common Stock and on representations of such holders made to the Company.
