Explanation of Responses:
(1)  Each restricted stock unit represents a contingent right to receive one share of the Issuer's common stock.
(2)  The reporter was initially granted restricted stock unit awards under the Rentrak 2011 Incentive Plan. In connection with the acquisition of Rentrak by the Issuer, pursuant to the Agreement and Plan of Merger and Reorganization, dated September 29, 2015 (the "Merger Agreement"), these were assumed by the Issuer and converted into restricted stock unit awards in respect of shares of the Issuer's common stock calculated based on the Exchange Ratio (as defined in the Merger Agreement).
(3)  The reporter was initially granted 2,587 restricted stock units. 863 shares vested on 10/1/2016, 863 vested on 10/1/2017 and 861 shares to vest on 10/1/2018, in each case subject to the reporter's continued status as a service provider of the Issuer at the time of each vesting date.
