Ensuring Your Vote is Counted

In advance of the Record Date, Capitol advises holders of its securities to move these securities into accounts which do not permit the lending of securities, so called cash accounts or segregated accounts, and out of accounts that permit the lending of securities, such as margin accounts. These steps are designed to ensure that votes related to common stock and warrants beneficially owned by stockholders and warrant holders are properly counted. Beneficial owners of common stock and warrants that have been lent out (either with or without the beneficial owners’ knowledge) are not permitted to vote those shares or warrants.
