7. PROMISSORY NOTES AND WARRANTS:

On June 18, 2009, the Company entered into a Note and Warrant Purchase Agreement (the "Note Purchase Agreement"), with a limited number of accredited investors. Pursuant to the Note Purchase Agreement, the Company sold an aggregate of $3,800,000 in principal amount of secured promissory notes (the "Notes") and 285,000 warrants (the "Note Warrants") to purchase shares of the Company's common stock. The Notes were payable in full on January 5, 2011 and incurred simple interest at the rate of 10.0% per year. The interest was payable a year after the closing date and at maturity. The Notes were secured by all of the assets of the Company.

The Note Warrants are immediately exercisable at an exercise price of $6.43 per share and expire three years after the date of issuance. Note Warrants to purchase 0.075 shares of the Company's common stock were issued for each $1.00 in principal amount of the Notes sold to each purchaser. The Note Purchase Agreement requires additional warrants (the "Additional Warrants") to be issued at the earlier of a year after the issuance date of the Notes, or the date on which the principal and interest on the Notes is paid in full. The Additional Warrants accrued ratably over the 365 day period at a rate of 7.5% of the aggregate principal amount of all Notes issued pursuant to the Note Purchase Agreement, and otherwise carry the same terms as the Note Warrants issued upon closing of the Note Purchase Agreement. If the Notes remained outstanding for a year, 285,000 Additional Warrants were to be issued. If the Notes, or a portion of the Notes, were redeemed prior to one year after the date the Notes were issued, the number of Additional Warrants issued were to be prorated for the time the Notes are outstanding.

Using a simulation model of discounted cash flows, the relative fair value of the Notes was calculated to be $3,229,675. The fair value of the Note Warrants and Additional Warrants was calculated to be $570,325. The fair value of the Note Warrants was calculated using the Black-Scholes model with the following assumptions: Expected life in years: 3; Estimated volatility: 30%; Risk-free interest rate: 1.86%; Dividend yield: 0%. The fair value of the Additional Warrants was calculated using the Black-Scholes model with a probability matrix for the number of warrants issued and the vesting date of the warrants: Expected life in years: 3; Estimated volatility: 30%; Dividend yield: 0%; Risk-free interest rate: weighted average based on the time to expiration with the 5 year US Treasury bill rate of 2.86%.

The proceeds from the Notes have been discounted for the relative fair value of the Note Warrants and Additional Warrants of $570,325, which was recorded as additional paid-in capital. The discount is being amortized over the life of the Notes using the effective interest method. For the year ended December 31, 2010, $55,433 of the discount was amortized to interest expense.

The Company incurred $196,353 of debt issuance costs which is being amortized over the life of the Notes using the effective interest method. The Company issued 20,684 shares of common stock to the placement agent for services in connection with the private placement of the Notes. The Company estimated the fair value of the services received to be $133,000, based on the agreement with the placement agent. For the year ended December 31, 2010, $19,293 of the debt issuance costs was amortized to interest expense.

In the first quarter of 2010, the Company repaid the principal and $262,356 of accrued interest outstanding on the Notes in full. Pursuant to the Note and Warrant Purchase Agreement, the Company issued 196,766 Additional Warrants on February 25, 2010. The Additional Warrants are immediately exercisable at an exercise price of $6.43 per share and expire three years after the date of issuance. As of December 31, 2010, the Company expensed $113,954 of unamortized debt issuance costs and $327,787 of unamortized discount, resulting in a loss on early extinguishment of debt of $441,741.

The holders of the Notes included certain directors or entities affiliated with them. Patrick Doherty, one of the Company's former directors, is president of Mariner Private Equity, LLC. The Company owed entities affiliated with Mariner Private Equity, LLC, $1,500,000 in principal and $103,562 in accrued interest. Mr. Doherty resigned from the board during 2011. The Company owed Michael Brown, one of the Company's directors, $100,000 in principal and $6,904 in accrued interest.
