EXHIBIT 11

EARNINGS PER SHARE

Basic earnings per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding for the period and, if there are dilutive securities, diluted earnings per share is computed by including common stock equivalents outstanding for the period in the denominator.

Common stock equivalents include shares issuable upon the exercise of stock options or warrants, net of shares assumed to have been purchased with the proceeds, using the treasury stock method.
