AHLB's wholly-owned subsidiary Actinium Holdings Ltd. ("AHL"), a Bermuda corporation, is the record holder of such shares and might have been deemed the direct beneficial owner of such shares; however, it has been dissolved for inadvertant failure to pay annual fees. AHLB has begun the process of applying for the reinstatement of AHL; pending such reinstatement, MSKCC and AHLB may not be able to vote, dispose of or benefit from such shares.
