        <footnote id="F1">Pursuant to the Agreement and Plan of Merger (the &quot;Merger Agreement&quot;), dated June 20, 2025, by and among Couchbase, Inc. (the &quot;Issuer&quot;), Cascade Parent Inc. (&quot;Parent&quot;) and Cascade Merger Sub Inc. (&quot;Merger Sub&quot;), Merger Sub merged with and into the Issuer (the &quot;Merger&quot;), with Issuer surviving the Merger and becoming a wholly owned subsidiary of Parent.</footnote>
        <footnote id="F2">At the effective time of the Merger (the &quot;Effective Time&quot;), these shares were automatically converted solely into the right to receive cash in an amount equal to $24.50 (without interest) per share (the &quot;Per Share Price&quot;), subject to the terms and conditions of the Merger Agreement.</footnote>
        <footnote id="F3">At the Effective Time, each outstanding restricted stock unit (&quot;RSU&quot;) that was unvested was cancelled and converted solely into the contingent right to receive a cash award (without interest) equal to (i) the total number of shares of common stock subject to such unvested RSU award immediately prior to the Effective Time, multiplied by (ii) the Per Share Price, less applicable withholding taxes. Each converted cash award will continue to have, and will be subject to, the same vesting terms and conditions (including acceleration provisions upon a qualifying termination of employment (if any)) as applied to the corresponding unvested RSU award immediately prior to the Effective Time, except for administrative changes that are not adverse to the former holder of the unvested RSU award.</footnote>
        <footnote id="F4">At the Effective Time, this option to purchase shares of the Issuer's common stock was fully vested and had an exercise price per share that was greater than the Per Share Price and, pursuant to the terms of the Merger Agreement, at the Effective Time, was
automatically cancelled for no consideration.</footnote>
