Notes:
(1)  All shares of convertible preferred stock are considered, on a
     supplementary 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.
