The Company follows Statement of Financial Accounting Standards (SFAS) No. 128,
Earnings Per Share, issued by the Financial Accounting Standards Board. Under
SFAS No. 128, the basic and diluted net loss per share of common stock for the
periods ended June 30, 1997 and 1998 is computed by dividing the net loss by the
weighted average number of common shares outstanding during the period,
including stock options issued at nominal amounts within twelve months of the
Company's initial public offering (IPO). Stock options issued at nominal amounts
within twelve months prior to the Company's IPO are considered outstanding for
all periods presented for the diluted calculation in accordance with the
Securities and Exchange Commission Staff Accounting Bulletin No. 98.
 
The Company's convertible preferred stock and other convertible instruments are
not considered outstanding for the diluted calculation since their effect is
antidilutive. The weighted average number of common shares outstanding excludes
1,200,000 shares of common stock subject to a contingent repurchase right of the
Company. The 1,200,000 shares will only be released upon the attainment of
certain revenue, net income and stock price milestones, as defined in an
agreement between Palomar and the Company. At June 30, 1998 such conditions were
not satisfied.
