Explanation of Responses:
1. As previously disclosed, on December 30, 2011, Liberty Radio, LLC, a wholly owned subsidiary of the Reporting Person, entered into a forward purchase contract (the "Forward Contract") with an unaffiliated counterparty covering up to a maximum of 315,000,000 notional shares of the Issuer's Common Stock. On May 7, 2012, the unaffiliated counterparty completed its initial hedge, and the number of notional shares of Common Stock covered by the Forward Contract was fixed at 302,198,700 shares. The Forward Contract expired on July 6, 2012 and will be physically settled on July 11, 2012. The forward price under the Forward Contract was equal to the "base price" of $2.15 per share plus an amount equal to the counterparty's internal funding costs plus a spread.
2. The shares of Common Stock are held directly by Liberty Radio, LLC, which is a wholly owned subsidiary of the Reporting Person.
