On September 4, 2012, the Company entered into an unsecured loan agreement with TMK-ENT, Inc. that provided for a $500,000 working capital revolving line of credit. Advances under the line of credit bear interest at 10% per year, payable annually. On November 13, 2012, the Company amended its loan agreement to increase the revolving line of credit agreement from $500,000 to $750,000, and on December 21, 2012 amended its loan agreement to increase the revolving credit agreement for $750,000 to $1,250,000. The note matures on December 21, 2014. Borrowings under the line of credit amount to $1,018,500 as of March 31, 2014 and December 31, 2013. In conjunction with the line of credit facility, the Company issued 1,250,000 warrants to purchase the Company’s common stock at varying prices from $1.38 to $1.62 per share. The warrants vest one year from issuance and have a ten year term. The fair market value of the warrants at grant date was determined utilizing the Black Scholes option pricing model and amounted to $1,839,250. The difference between the fair market value of the warrants and draws on the line of credit is $820,750 as of March 31, 2014 and December 31, 2013, which is recorded as deferred debt discount. The deferred debt discount will be recognized and recorded as debt discount as the Company continues to borrow against the line of credit. Debt discount costs will be recognized as the Company draws down the available line of credit, and will be amortized over the remaining term of the loan. As a result of the amortization of the debt discount, the Company expensed $84,790 and $199,852, respectively, for the three months ended March 31, 2014 and 2013.

Annual maturities of debt are as follows:

2014 (includes TMK-ENT, Inc. line of credit repayment)	$	1,028,136
