(1) On November 4, 2014, Liberty Media Corporation ("Liberty") completed the spin-off (the "spin-off") of the Issuer (its former wholly-owned subsidiary), which was effected by the distribution to each holder of its common stock of shares of the corresponding series of the Issuer's common stock. In connection with the completion of the spin-off, all equity awards held by the reporting person with respect to Liberty's common stock (each an "Original LMC Award") were adjusted pursuant to the anti-dilution provisions of the incentive plan under which the equity awards were granted, such that the reporting person received (i) an adjustment to the exercise price or base price, as applicable, and number of shares relating to the Original LMC Award and (ii) an equity award relating to shares of the corresponding series of the Issuer's common stock. These adjustments were approved by the Issuer's board of directors pursuant to Rule 16b-3 under the Securities Exchange Act of 1934, as amended.
(2) The derivative security is fully vested.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
