(1) At the time of the issuer's Class A common stock becoming registered under the Securities Exchange of 1934, the reporting person held an approximately 47% interest in Virgin Mobile USA, LLC ("VMU"). Pursuant to a reorganization and purchase agreement, the reporting person and the issuer agreed to effect the following transactions immediately prior to the consummation of the issuer's initial public offering (the "IPO"): (1) the reporting person will contribute a portion of its limited liability company interests in VMU ("LLC Interests") to the issuer in exchange for 1,333,333 shares of Class A common stock of the issuer (which the reporting person will sell in the IPO) and one share of Class B common stock of the issuer, and (2) the reporting person will sell a portion of its LLC Interests to the issuer for $136.0 million.
(2) Following the transactions described in footnote (1) and prior to the consummation of the IPO, VMU will convert into a Delaware limited partnership, Virgin Mobile USA, L.P., which will become an indirect, majority-owned subsidiary of the issuer. As a result of this conversion, the reporting person's remaining LLC Interests will be converted into an approximately 18.5% limited partnership interest in Virgin Mobile USA, L.P., which interest will initially be exchangeable for 12,058,626 shares of Class A common stock of the issuer.
