(1)	Reflects shares acquired from CNET, pursuant to the exercise of the "top-up" option provided in the Agreement and Plan of Merger, dated as of May 15, 2008 (the "Merger Agreement"), by and among CBS Corporation ("CBS"), Ten Acquisition Corp., a wholly-owned subsidiary of CBS ("Ten Acquisition"), and CNET Networks, Inc. ("CNET").
(2)	On June 30, 2008, at the effective time of the merger these shares were cancelled and ceased to exist.
(3)	The shares were held by Ten Acquisition and may also be deemed to be beneficially owned by (a) CBS, (b) NAIRI Inc. ("NAIRI"), which owns approximately 80% of CBS' voting stock, (c) NAIRI's parent corporation, National Amusements Inc. ("NAI"), and (d) Mr. Sumner M. Redstone, who is the controlling stockholder of NAI. Following the consummation of the share purchase pursuant to the exercise of the "top-up" option, CBS contributed all of the shares directly held by it to Ten Acquistion on June 27, 2008.
(4)	Reflects all of the outstanding shares of CNET not tendered in the offer and deemed acquired by CBS pursuant to the consummation of the merger. At the effective time of the merger, these shares were cancelled and ceased to exist.
(5)	Prior to the merger, CBS held 100 shares of the common stock of Ten Acquisition, par value $0.01 per share, which shares represented all of the issued and outstanding capital stock of Ten Acquisition. Upon the merger of Ten Acquisition with and into CNET, each share of Ten Acquisition held by CBS converted into one share of CNET. Ten Acquisition's separate corporate existence ceased and CNET survived the merger as a direct, wholly-owned subsidiary of CBS.
