Notes:
 (1)    All shares of convertible preferred stock are considered, on a pro forma
        basis, to be common stock and are included using the if-converted method
        on the dates of their original issuance.
 (2)    In accordance with Securities and Exchange Commission Staff Accounting
        Bulletin No. 83, issuances of common stock, common stock equivalents and
        Series J Preferred Stock within one year prior of the initial filing of
        the registration statement, at share prices below the assumed initial
        public offering price of $10.00 per share are considered to have been
        made in anticipation of the contemplated public offering for which this
        registration statement was prepared. Accordingly, these stock issuances
        are treated as if issued and outstanding, using the treasury stock
        method for options, since the inception of the Company.
