Explanation of Responses:

1. Pursuant to the Agreement and Plan of Merger, dated as of December 29, 2025 (the "Merger Agreement") among the Issuer, Cvent Atlanta, LLC ("Parent"), and Summit Sub Corp. ("Merger Sub"), on April 1, 2026, Merger Sub merged with and into the Issuer, with the Issuer continuing as the surviving company and a wholly-owned subsidiary of Parent (the "Merger"). At the effective time of the Merger, each outstanding share of Issuer common stock was automatically canceled and converted into the right to receive cash in an amount equal to $8.10 per share, without interest, with similar treatment for outstanding RSUs.

2. Shares are held directly by Lynrock Lake Master Fund LP ("Lynrock Fund"). The investment manager and general partner of Lynrock Fund are Lynrock Lake LP ("Lynrock") and Lynrock Lake Partners LLC ("Lynrock GP"), respectively, and each may be deemed to beneficially own the shares held by Lynrock Fund. Cynthia Paul is the Chief Investment Officer of Lynrock and Sole Member of Lynrock GP and may be deemed to beneficially own the shares held by Lynrock Fund. Each of Lynrock, Lynrock GP and Ms. Paul disclaims beneficial ownership in these shares except to the extent of its or her respective pecuniary interest therein.
