        <footnote id="F1">On November 9, 2006, Ingrid Zerbe exercised an option to purchase 225,000 shares. The exercise was rescinded on January 10, 2007 due to the fact that the exercise was incorrectly authorized.</footnote>
        <footnote id="F2">The issuer acquired a subsidiary, IntelGenx Corp.,in April of 2006. As part of this Acquisition, Ingrid Zerbe became Secretary of the Issuer and acquired 4,709,643.5 exchangeable shares of the Company's Canadian subsidiary, 6544631 Canada Inc. These 4,709,643.5 shares are exchangeable, on a one for one basis, into shares of common stock of the Issuer at Ingrid Zerbe's discretion. Prior to exchanging the exchangeable shares for shares of the issuer, Ingrid Zerbe has the right to vote 4,709,643.5 shares of the Issuer. It is because of these vote rights, which indicate control over the shares, that these shares are included on this Form 4. The 4,709,643.5 shares of the Issuer have not been registered for resale at this time. The acquisition and the terms under which the exchangable shares were issued are more completely described in the Issuer's Report on the SB-2 filed on July 3, 2006.</footnote>
