Explanation of Responses:
1. Each restricted stock unit represents a contingent right to receive one share of the Issuer's common stock.
2. Due to an administrative error, the number of shares of common stock beneficially owned by the Reporting Person was overreported by one share in previous Form 4 filings. The amount of securities beneficially owned by the Reporting Person is accurate as of the date of this filing.
3. Granted pursuant to the terms of comScore, Inc. 2007 Equity Incentive Plan. 3,333 shares vested on 2/15/2017, 3,333 shares vest on 2/15/2018 and 3,334 shares to vest on 2/15/2019, subject to the reporter's continued status as a service provider of the Issuer at the time of each vesting date.
