and Stock-Based Compensation

Stock Option Plan.

The Company has adopted a stock option plan for the granting of options or restricted shares to employees, officers, directors and consultants of the Company that originally provided for the purchase of up to 7,000,000 shares of common stock, at the discretion of the Board of Directors. Subsequent to the adoption, the Board of Directors and stockholders approved additional common stock shares aggregating 6,000,000 to be available for grant, for a total of 13,000,000 shares of common stock reserved for issuance under the Company’s 2001 Stock Option Plan, as amended. Stock option grants may not be priced less than the fair market value of the Company’s common stock at the date of grant. Options granted are generally for ten-year periods, except that incentive stock options granted to a 10% stockholder (as defined) are limited to five-year terms.

In June, 2015, there were 2,248,000 stock options authorized by the Board of Directors and issued to Company officers, employees and directors with an exercise price ranging from $0.09 to $0.10, vesting over three years, with terms of either five or ten years. During the fiscal year ended June 30, 2015, the Company incurred stock compensation expense of approximately $0.1 million. The Company did not incur any stock compensation expense in the fiscal year ended June 30, 2014. The Company expects to record additional stock compensation expense of approximately $75 over the estimated weighted average vesting period of three years.

The Company used the following assumptions to calculate the fair value of the stock option grants using the Black-Scholes option pricing model on the grant date:

Risk Free Interest Rate	1.49%	to	1.99%
Volatility	93.9%	to	106.0%
Term (years)	5	to	10
Dividend Rate		0.00%
Closing Price of Common Stock		$0.09

The Company calculates expected volatility for a stock-based grant based on historic daily stock price observations of its common stock during the period immediately preceding the grant that is equal in length to the expected term of the grant. The expected term of the options is estimated based on the Company’s historical exercise rate and forfeiture rates are estimated based on employment termination experience. The risk free interest rate is based on U.S. Treasury yields for securities in effect at the time of grants with terms approximating the term of the grants. The assumptions used in the Black-Scholes option valuation model are highly subjective, and can materially affect the resulting valuations.

The following options and potentially dilutive shares for convertible notes payable (see Note 6. Senior Credit Facility, Subordinated Convertible Note Payable, net - CD Financial, LLC and other Long Term Debt) were not included in the computation of weighted average diluted common shares outstanding as the effect of doing so would be anti-dilutive for fiscal years ended June 30, 2015 and 2014:

	Fiscal Year Ended
	June 30,
	2015		2014
Anti-dilutive stock options		2,139,550		1,236,770
Anti-dilutive shares for convertible notes payable		-		8,230,769
Total anti-dilutive shares		2,139,550		9,467,539

The intrinsic value of options outstanding and exercisable at June 30, 2015 and 2014 was $0 and $68, respectively.
