(a) Pursuant to the Securities and Exchange Commission Staff Accounting Bulletin
No. 83, common stock and common stock equivalents issued at prices below the
assumed initial public offering price per share during the twelve-month period
immediately preceding the initial filing date of the Company's Registration
Statement for its public offering have been included as outstanding for the
period.

(b) Computed on a pro forma basis assuming conversion of the convertible note
and all outstanding shares of preferred stock into common stock (which, in each
case, occurred on March 15, 1996 immediately prior to the initial public
offering) as if such conversion occurred on October 1, 1995. Pro forma loss per

share reflects adjustments to eliminate accrued preferred stock dividends.
