        <footnote id="F1">Each restricted stock unit represents a contingent right to receive one share of BITI common stock, par value $.00025.</footnote>
        <footnote id="F2">Represents the automatic grant of 7,500 restricted stock units, granted pursuant to the Company's 2002 Stock Incentive Plan, as amended and restated, upon election to the Board of Directors at the Annual Meeting of Stockholders on May 14, 2008, determined by using the closing price on May 14, 2008.  The restricted stock units shall vest in one-twelfth (1/12) increments on each one-month anniversary from the date of grant; provided, however, that the shares underlying the restricted stock units shall not be issued to the directors until the director's cessation of service on the Board of Directors.</footnote>
        <footnote id="F3">Represents only those shares underlying the restricted stock units.  The director may beneficially own BITI securities not required to be recorded herein.</footnote>
