Computation of Net Loss Per Common Share [Abstract]

COMPUTATION OF NET LOSS PER COMMON SHARE

8. COMPUTATION OF NET LOSS PER COMMON SHARE

     Basic net loss per common share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period, excluding restricted stock that has been issued but is not yet vested. Diluted net loss per common share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period plus additional weighted-average common equivalent shares outstanding during the period. Common equivalent shares result from the assumed exercise of outstanding stock options and warrants (the proceeds of which are then presumed to have been used to repurchase outstanding stock using the treasury stock method) and the vesting of restricted shares of common stock. In loss periods, certain of the common equivalent shares are excluded from the computation of diluted net loss per share, because their effect would have been anti-dilutive.

     For the nine month periods ended June 30, 2011 and 2010, the following options and warrants to purchase shares of common stock and restricted stock units were excluded from the computation of diluted net loss per share, as the inclusion of such shares would be anti-dilutive:

	2011		2010
Stock options		7,908,679		6,257,087
Stock warrants		6,155,170		12,240,437
Restricted stock units (1)		1,798,812		2,050,644

(1) Includes 1,367,231 and 1,069,680 shares of restricted stock at June 30, 2011 and 2010, respectively, awarded to directors that have vested but are still restricted until the directors resign.
