Stock Option Program Description

     As of June 30, 2011, the Company had two equity compensation plans, the 1996 Stock Option Plan (the “1996 Plan”) and the 2006 equity compensation plan (the “2006 Plan”). The 1996 Plan has expired for the purposes of issuing new grants. However, the 1996 Plan will continue to govern awards previously granted under that plan. The 2006 Plan has been approved by the Company’s Shareholders. Equity compensation grants are designed to reward employees and executives for their long term contributions to the Company and to provide incentives for them to remain with the Company. The number and frequency of equity compensation grants are based on competitive practices, operating results of the company, and government regulations.

     The 2006 Plan has a total of 3,000,000 shares reserved for issuance, of which 1,614,000 shares were available for grant as of June 30, 2011. All stock options have terms of between five and ten years and generally vest and become fully exercisable from one to three years from the date of grant.

     As of June 30, 2011, the total compensation cost related to non-vested awards not yet recognized is $319,000. The weighted average period over which the future compensation cost is expected to be recognized is 18 months.

     The following table summarizes information about stock options outstanding and exercisable at June 30, 2011:

(1)	Aggregate intrinsic value represents the value of the closing price per share of our common stock on the last trading day of the fiscal period in excess of the exercise price multiplied by the number of options outstanding or exercisable, except for the “Exercised” line, which uses the closing price on the date exercised.
(2)	Number of shares includes options vested and those expected to vest net of estimated forfeitures.

     The exercise prices of the options outstanding at June 30, 2011 ranged from $0.21 to $4.35. The weighted average grant-date fair value of options granted during the six months ended June 30, 2011 was $0.79. There were no options granted during the six months ended June 30, 2010. The Company’s policy is to issue shares from its authorized shares upon the exercise of stock options.

     Unvested share activity for the six months ended June 30, 2011 is summarized below:

	Unvested			Weighted-Average
	Number of			Grant Date Fair
	Options			Value
Unvested balance at December 31, 2010		435,000		$	0.93

Forfeited		(86,000	)	$	0.90
Unvested balance at June 30, 2011		353,000		$	0.91

     The fair values of all stock options granted during the six months ended June 30, 2011 were estimated on the date of grant using the Black-Scholes option-pricing model with the following range of assumptions:

	For the six months ended
	June 30,			June 30,
	2011			2010
Expected life (in years)		2.5 — 6.5			—
Average risk-free interest rate		2.00	%		—
Expected volatility		107 — 132	%		—
Expected dividend yield		0	%		—
Forfeiture rate		3	%		—

     The estimated fair value of grants of stock options to nonemployees of the Company is charged to expense in the financial statements. These options vest in the same manner as the employee options granted under each of the option plans as described above.
