An aggregate of 80,000 of these warrants become exercisable only upon the attainment of specified events. No such events were obtained during the nine months ended September 30, 2013.

 During the nine months ended September 30, 2013, the Company issued to certain members of a newly established advisory board, warrants to purchase an aggregate of 70,000 shares of the Company’s common stock. Such warrants have an exercise price of $1.72 per share and have a two year term. The Company recorded the estimated grant date fair value of these warrants using the Black-Scholes option valuation model as a component of general and administrative expense.

 During the nine months ended September 30, 2013, there were 6,437,541 warrants exercised pursuant to cashless transactions resulting in the issuance of 4,336,741 shares of common stock, 3,577,779 warrants exercised for cash resulting in the issuance of 3,577,779 shares of common stock and proceeds to the Company of approximately $2,014,000 and 688,749 warrants that expired.

 As of September 30, 2013, warrants to purchase 9,317,048 shares of common stock at prices ranging from $0.50 to $1.72 were outstanding. All warrants are exercisable as of September 30, 2013, and expire at various dates through December 2016, with the exception of an aggregate of 330,000 warrants, which become exercisable only upon the attainment of specified events.

 Stock-Based Compensation

 As of September 30, 2013, the Company had two active stock-based compensation plans for employees and nonemployee directors, which authorize the granting of various equity-based incentives including stock options and restricted stock.

 The Company estimates the fair value of its stock options using a Black-Scholes option-pricing model, consistent with the provisions of ASC 718, Compensation – Stock Compensation. The fair value of stock options granted is recognized to expense over the requisite service period. Stock-based compensation expense is reported in general and administrative, sales and marketing, engineering and customer service expenses based upon the departments to which substantially all of the associated employees report and credited to additional paid-in capital.  Stock-based compensation expense related to equity options was approximately $142,000 and $411,000 for the three and nine months ended September 30, 2013, respectively. Stock-based compensation expense related to equity options was approximately $145,000 and $426,000 for the three and nine months ended September 30, 2012, respectively. 

 In January of 2010, the Company issued 847,258 shares of restricted stock to members of management and the Board. These shares vest quarterly over a three-year period. The restricted shares were issued as compensation for the cancellation of 1,412,096 options held by members of management and the Board. The Company evaluated the exchange in accordance with ASC 718 and determined there was no incremental cost to be recorded in conjunction with the exchange as the fair value of the options surrendered at the modification date exceeded the fair value of the restricted shares issued at the modification date. Stock-based compensation expense related to these restricted stock grants was $0 for the three and nine months ended September 30, 2013. Stock-based compensation expense related to these restricted stock grants was approximately $9,000 and $28,000 for the three and nine months ended September 30, 2012, respectively. 

 During March 2011, the Company granted 880,000 performance units to certain key employees that grant the holder the right to receive compensation based on the appreciation in the Company’s common stock in the event of transfer of control of the Company ("Performance Units"). As the vesting of the Performance Units is contingent upon the sale of the Company, the expense associated with the granting of the Performance Units was not material. The Performance Units issued to such key employees were terminated, and exchanged for options to purchase a total of 435,000 shares of common stock during the three months ended March 31, 2012.

 ASC 718 requires the use of a valuation model to calculate the fair value of stock-based awards. The Company has elected to use the Black-Scholes option-pricing model, which incorporates various assumptions including volatility, expected life, and interest rates. The Company is required to make various assumptions in the application of the Black-Scholes option-pricing model. The Company has determined that the best measure of expected volatility is based on the historical weekly volatility of the Company’s common stock. Historical volatility factors utilized in the Company’s Black-Scholes computations for the nine months ended September 30, 2013 and 2012 ranged from 78% to 144%. The Company has elected to estimate the expected life of an award based upon the SEC approved “simplified method” noted under the provisions of Staff Accounting Bulletin No. 110. The expected term used by the Company during the nine months ended September 30, 2013 and 2012 was 5.9 years. The difference between the actual historical expected life and the simplified method was immaterial.  The interest rate used is the risk free interest rate and is based upon U.S. Treasury rates appropriate for the expected term. Interest rates used in the Company’s Black-Scholes calculations for the nine months ended September 30, 2013 and 2012 was 2.6%. Dividend yield is zero as the Company does not expect to declare any dividends on the Company’s common stock in the foreseeable future.

 In addition to the key assumptions used in the Black-Scholes model, the estimated forfeiture rate at the time of valuation is a critical assumption.  The Company has estimated an annualized forfeiture rate of approximately 0% for corporate officers, 4.1% for members of the Board of Directors and 6.0% for all other employees.  The Company reviews the expected forfeiture rate annually to determine if that percent is still reasonable based on historical experience.

 In March 2013, the Company issued 410,000 options under existing stock-based compensation plans to certain members of senior management, certain members of the Board of Directors and certain employees. Such options have an exercise price of $0.93 per share. In May and July 2013, the Company issued 42,500 and 35,000 options, respectively, under existing stock-based compensation plans to certain employees. The exercise price of the May 2013 grant was $1.00 per share and the exercise price of the July 2013 grant was $2.30 per share.

 A summary of the activity under the Company’s stock option plans is as follows:

	Options			Weighted-Average Exercise Price
Balance at December 31, 2012		3,031,221		$	0.82
Granted		487,500		$	1.03
Expired/Cancelled		(27,500	)	$	1.00
Exercised		(32,713	)	$	0.27
Balance at September 30, 2013		3,458,508		$	0.85

 The per share weighted-average grant date fair value of options granted during the nine months ended September 30, 2013 was $0.74.
