 Stock-Based Compensation

 As of June 30, 2014, 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. On July 1, 2014, the Company began soliciting written consents from its shareholders to approve an amendment to the Company’s 1999 Stock Option Plan to increase the number of shares authorized for issuance thereunder from approximately 4.0 million to approximately 7.0 million (the “Amendment”).  As of July 21, 2014, the Company had received written consents approving the Amendment from over 50% of the Company’s stockholders. As such, the Amendment was approved.

 The Company estimates the fair value of its stock options using a Black-Scholes option-pricing model, consistent with the provisions of ASC No. 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 $148,000 and $306,000 for the three and six months ended June 30, 2014, respectively. Stock-based compensation expense related to equity options was approximately $144,000 and $269,000 for the three and six months ended June 30, 2013, respectively.

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 six months ended June 30, 2014 and 2013 ranged from 78% to 135%. 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 six months ended June 31, 2014 and 2013 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 six months ended June 30, 2014 and 2013 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.

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

	Options			Weighted- Average Exercise Price
Balance at December 31, 2013		3,783,411		$	0.94
Granted		15,000		$	2.31
Expired/Cancelled		(46,250	)	$	1.85
Exercised		(83,745	)	$	0.78
Balance at June 30, 2014		3,668,416		$	0.94

      In December 2013, the Company issued 144,000 shares of its common stock to certain members of the Company’s Board of Directors as compensation for services to be rendered through December 2014. Such shares are forfeitable should the Board members’ service be terminated.  For the three and six months ended June 30, 2014, the Company recorded $60,000 and $119,000, respectively, as compensation expense.
