(1) Certain wholly owned subsidiaries of Comcast Corporation ("Comcast") have entered into an Equityholders' Agreement dated as of November 28, 2008 (the "Equityholders' Agreement") with Clearwire Corporation (the "Issuer") and the other parties thereto (collectively, the "Unaffiliated Stockholders").
(2) By virtue of the Equityholders' Agreement, Comcast and the Unaffiliated Stockholders may be deemed to be members of a group under Section 13(d) of the Securities Exchange Act of 1934, as amended, that, in the aggregate, beneficially owns more than 10% of the Issuer's outstanding shares of Class A Common Stock. The number of securities of the Issuer and Clearwire Communications, LLC, a subsidiary of the Issuer ("Clearwire LLC"), beneficially owned by Comcast as reported herein does not include the holdings of any Unaffiliated Stockholders. Comcast does not have any "pecuniary interest" in the securities of the Issuer or any of its subsidiaries owned by the Unaffiliated Stockholders.
(3) Each share of Class B Common Stock of the Issuer, together with one Class B Common Unit of Clearwire LLC (a "Class B Common Unit"), is exchangeable at any time into one fully paid and nonassessable share of Class A Common Stock of the Issuer, subject to certain limited exceptions, without an expiration date. There is no exercise price payable in connection with exchanges.
(4) On November 9, 2009, Comcast entered into an Investment Agreement (the "Investment Agreement") with the Issuer, Clearwire LLC, Sprint Nextel Corporation, Time Warner Cable Inc., Intel Corporation, Eagle River Holdings, LLC, and Bright House Networks, LLC pursuant to which Comcast will invest a total of approximately $196 million in Clearwire LLC in exchange for shares of Class B Common Stock and Class B Common Units over a series of three closings, the first of which occurred on November 13, 2009. Comcast received the shares of Class B Common Stock and Class B Common Units reported in Table II on November 13, 2009 pursuant to the first closing under the Investment Agreement in exchange for a $132,489,881.94 investment in Clearwire LLC and based upon a purchase price of $7.33 per share.
(5) The shares of Class B Common Stock and Class B Common Units reported in Table II are owned indirectly by Comcast through indirect wholly owned subsidiaries.
