Exhibit 11

Earnings Per Share Calculations

Basic net loss per share are computed by dividing net loss by the weighted
average number of shares outstanding for the year. Diluted loss per share is similar except that the weighted average number of
shares outstanding is increased by shares issuable upon exercise of stock options and warrants for which the market price exceeds
exercise price, less shares that could have been purchased by the Company with the related proceeds.
