I. Net Loss Per Share

Under the 

two

-class method, for periods with net income, basic net income per share of common stock is computed by dividing the net income attributable to shares of common stock by the weighted average number of shares of common stock outstanding during the period. Net income attributable to shares of common stock is computed by subtracting from net income the portion of current period earnings that participating securities would have been entitled to receive pursuant to their dividend rights had all of the period’s earnings been distributed. 

No

 such adjustment to earnings is made during periods with a net loss as the holders of the participating securities have 

no

 obligation to fund losses. Diluted net income (loss) per share of common stock is computed under the 

two

-class method by using the weighted average number of shares of common stock outstanding plus the potential dilutive effects of stock options and warrants. In addition, the Company analyzes the potential dilutive effect of the outstanding convertible securities under the if-converted method when calculating diluted income (loss) per share of common stock in which it is assumed that the outstanding convertible securities convert into common stock at the beginning of the period or date of issuance, if the convertible security was issued during the period. The Company reports the more dilutive of the approaches (

two

-class or if-converted) as its diluted net income (loss) per share of common stock during the period.

Diluted net loss per share of common stock is the same as basic net loss per share of common stock for all periods presented because the effects of potentially dilutive items were anti-dilutive given the Company’s net loss. The following securities, presented on a common stock equivalent basis, have been excluded from the calculation of weighted average number of shares of common stock outstanding because their effect is anti-dilutive:
