Explanation of Responses:
(1)  The Redeemable Convertible Preferred Stock is immediately convertible, provided that such conversion would not cause the Reporting Person and its affiliates to beneficially own, in the aggregate, a number of shares of the Issuer's capital stock that represents in excess of 19.99% of the Issuer's voting power, subject to certain exceptions pursuant to the terms of the Redeemable Convertible Preferred Stock. The Redeemable Convertible Preferred Stock has no expiration date.
(2)  The securities reported as directly beneficially owned by the designated Reporting Person may be deemed to be indirectly beneficially owned by each of the Reporting Owners listed below, each of whom is a managing member of One Palmer Square Associates VIII, LLC, the sole general partner of the designated Reporting Person. Pursuant to Instruction 4(b)(iv) of Form 4, each such individual has elected to report as indirectly beneficially owned the entire number of securities owned by the designated Reporting Person, however each of them disclaims beneficial ownership of any securities, and any proceeds thereof, that exceed his or her pecuniary interest therein and/or that are not actually distributed to him or her.
(3)  As managing members of the sole general partner of DP VIII Associates, L.P., each Reporting Owner listed below may also be deemed to indirectly beneficially own the securities of the Issuer held by DP VIII Associates, L.P., as reported on a Form 4 for DP VIII Associates, L.P. filed on the same date as this Form 4.
