3.	Net Loss Per Share

Net loss per share is computed by dividing the net loss by the weighted average number of shares of common stock outstanding. Any outstanding stock options and warrants have not been included in the calculation of the diluted net loss per share because to do so would be anti-dilutive. Accordingly, the numerator and the denominator used in computing both basic and diluted net loss per share for each period are the same.

The following outstanding options and warrants were excluded from the computation of basic and diluted net loss per share for the periods presented because their effect would have been anti-dilutive (in thousands):
