        <footnote id="F1">The Sponsor Warrants are identical to the warrants included in the units that were sold by the Issuer in its initial public offering, except for those differences set forth in the Issuer's registration statement on Form S-1 (File No. 333-168798). In addition, the Sponsor Warrants generally are not transferable, assignable or salable until 30 days after the completion of the Issuer's initial business combination and will expire worthless if the Issuer does not complete an initial business combination within 21 months from the closing of the Issuer's initial public offering.</footnote>
