Upon the resignation and forfeiture by Ketan Seth, David Bauer, the Issuer's interim Chief Executive Officer and Chief Financial Officer, was appointed as the managing member of BHM and holds voting and investment discretion with respect to the securities held of record by the Sponsor. As such, Mr. Bauer may be deemed to have beneficial ownership of the securities held of record by the Sponsor. Mr. Bauer disclaims any beneficial ownership except to the extent of his pecuniary interest therein.
