[1] For the three and nine months ended June 30, 2013, options to purchase 56,546 and 131,152 shares of common stock, respectively, were outstanding but not included in the computation of diluted net income per common share because their effect would have been anti-dilutive. For the three and nine months ended June 30, 2012, options to purchase 110,726 and 133,652 shares of common stock, respectively, were outstanding but not included in the computation of diluted net income per common share because their effect would have been anti-dilutive.

[2] For the three and nine months ended June 30, 2012, a warrant to purchase 370,899 shares of common stock was outstanding but not included in the computation of diluted net income per common share because the warrant's exercise price was greater than the average market price of the common stock, and, therefore, its effect would have been anti-dilutive.
