Options

We have two nonqualified stock option plans approved by shareholders with an aggregate of 950,000 shares remaining available for grant under one plan as of September 30, 2013. The other plan terminated during the three months ended September 30, 2013.  The exercise price of the options are established by the Board of Directors on the date of grant and are generally equal to the market price of the stock on the grant date.  The Board of Directors may determine the vesting period for each new grant. Options issued are exercisable in whole or in part for a period as determined by the Board of Directors of up to ten years from the date of grant.

We estimate the fair value of each option award at the grant date by using the Black-Scholes option pricing model. We did not award any options during the three or nine months ended September 30, 2013.

Certain options awarded prior to the year ended December 31, 2012 are amortized over certain future vesting periods or contained performance-based vesting terms, and consequently during the nine months ended September 30, 2013, we charged to operating expenses $5,894 for these options.

The following table summarizes our stock option activity for the nine months ended September 30, 2013:

The following table sets forth the warrants outstanding at September 30, 2013:

			Weighted-

Total		31,328,155	$	0.73

During the nine months ended September 30, 2013, pursuant to our 8% convertible promissory notes, we issued warrants to purchase 4,375,004 shares of our common stock pursuant to our issuance and sale of our 8% convertible promissory notes, at an initial exercise price of $0.60 per share. These warrants had fair values on their dates of issuances of $249,151 which was recorded as a credit to derivative liabilities and a charge to debt discount associated with our 8% convertible promissory notes. See Notes 5 and 6 for further discussion of these warrants. The estimated fair value of the warrants was computed by a third party using Monte Carlo simulation models.

In addition, the fair value of a previously issued warrant which is being amortized over a service period spanning multiple reporting periods, was revalued using the Black-Scholes option pricing model, at the end of each reporting period. No revaluation was necessary for the three months ended September 30, 2013 and during the nine months ended September 30, 2013, we decreased the fair value by $2,990 and recorded a credit in our statement of operations.
