        <footnote id="F1">Reflects disposition following a tender pursuant to the offer by Buzz Merger Sub Inc. (&quot;Merger Sub&quot;) to purchase all of the Issuer's outstanding common stock at a price of $15.00 per share in cash, without interest, less any applicable withholding taxes, upon the terms and conditions set forth in Merger Sub's Offer to Purchase, dated January 13, 2020, and the related letter of transmittal.</footnote>
        <footnote id="F2">Reflects disposition pursuant to that certain Agreement and Plan of Merger, dated December 20, 2019, by and among IAC/InterActiveCorp, Merger Sub and the Issuer, pursuant to which Merger Sub merged with and into the Issuer on February 11, 2020 (the &quot;Merger&quot;). At the effective time of the Merger, each Issuer restricted stock unit held by the Reporting Person became fully vested and was cancelled and converted into the right to receive an amount in cash, less applicable withholding taxes, equal to (x) the total number of shares of Issuer common stock underlying such restricted stock units multiplied by (y) $15.00. Each restricted stock unit represents a contingent right to receive one share of Issuer common stock. The restricted stock units do not have an expiration date.</footnote>
