        <footnote id="F1">Reflects disposition of Issuer common stock with the consummation of the transactions contemplated by the Agreement and Plan of Merger (the
&quot;Merger Agreement&quot;), dated as of July 20, 2022, by and among Issuer, Amazon.com, Inc. (&quot;Parent&quot;) and Negroni Merger Sub, Inc., a wholly
owned subsidiary of Parent (&quot;Merger Sub&quot;), including the consummation of the merger (the &quot;Merger&quot;) between Issuer and Merger Sub on
February 22, 2023. Pursuant to the Merger Agreement, as of the effective time of the Merger (the &quot;Effective Time&quot;), each share of Issuer
common stock, par value $0.001 per share (&quot;Shares&quot;) issued and outstanding immediately prior to the Effective Time was converted
automatically into the right to receive $18.00 in cash, without interest (the &quot;Merger Consideration&quot;).</footnote>
        <footnote id="F2">Each restricted stock unit (&quot;RSU&quot;) represents a contingent right to receive one share of the issuer's common stock. RSUs convert into the
issuer's common stock on a one-for-one basis.</footnote>
        <footnote id="F3">Pursuant to the Merger Agreement, at the Effective Time, each outstanding RSU granted under any Issuer Stock Plan that was unvested as of
the Effective Time, by virtue of the Merger, was converted into the right to receive an amount in cash equal to the product of (i) the Merger
Consideration and (ii) the aggregate number of Shares subject to such unvested RSU as of immediately prior to the Effective Time (the
&quot;Unvested RSU Payment&quot;), provided that such Unvested RSU Payment (x) shall be subject to the same vesting and forfeiture provisions as were
applicable to such unvested RSU immediately prior to the Effective Time, (y) shall vest in installments over the remainder of the vesting schedule
of such RSU based on the same percentage of the RSU that would have vested on each applicable vesting date and (z) shall be subject to
forfeiture on the same terms and conditions as were applicable to such RSU, subject to any required withholding of taxes.</footnote>
        <footnote id="F4">The RSUs vest in equal annual installments over four years on the anniversary of the vesting commencement date, subject to the reporting
person's continuous service as of each such date.</footnote>
        <footnote id="F5">The RSUs vest annually over four years, with 50% of the RSUs units vesting on the first anniversary of the grant date; 20% vesting on the
second anniversary of the grant date; and 15% vesting on each of the third and fourth anniversaries of the grant date, subject to reporting
person's continuous service as of each such date.</footnote>
