(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 as of 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 3,680 restricted stock units. 920 shares vested on 9/24/2016, 920 vested on 9/24/2017, 920 shares to vest on 9/24/2018 and 920 shares to vest on 9/24/2019, in each case subject to the reporter's continued status as a service provider of the Issuer at the time of each vesting date.
