Note 8.  Note Payable


In June 2012, the Company entered into a Loan and Security Agreement (the “Credit Agreement”) with Oxford Finance LLC (“Oxford”) and Horizon Technology Finance Corporation (“Horizon”). The Credit Agreement provides for a secured term loan of up to $10 million, with 50% of any loans to be funded by Oxford and 50% to be funded by Horizon. The aggregate loan amount may be advanced in two tranches of $5 million each. The first tranche (the “Term A Loan”) was made available to the Company on June 27, 2012 and the second tranche (the “Term B Loan”) was to be made available, if at all, during the period beginning on the date that the Company achieved positive data in its Phase III clinical trial of RFA and ThermoDox® (the HEAT Study) and ending on March 31, 2013.  On January 31, 2013, the Company announced it did not meet the primary endpoint of the HEAT Study, therefore the second tranche was not drawn down.


The Term A Loan is scheduled to mature on October 15, 2015.   The obligations under the Credit Agreement are secured by substantially all assets of the Company other than its intellectual property and certain other agreed-upon exclusions.


The Term A Loan bears interest at a fixed rate of 11.75%. However, for the period extending from inception through May 1, 2013 for the Term A Loan, the Company was required to make interest payments only. The Company was also obligated to pay other customary facility fees for a credit facility of this size and type.


The Credit Agreement contains customary covenants, including covenants that limit or restrict the Company’s ability to incur liens, incur indebtedness, make certain restricted payments, merge or consolidate and make dispositions of assets. Upon the occurrence of an event of default under the Credit Agreement, the lenders may cease making loans, terminate the Credit Agreement, declare all amounts outstanding to be immediately due and payable and foreclose on or liquidate the Company’s assets that comprise the lenders’ collateral. The Credit Agreement specifies a number of events of default (some of which are subject to applicable grace or cure periods), including, among other things, non-payment defaults, covenant defaults, a material adverse change in the Company’s business, cross-defaults to other materials indebtedness, bankruptcy and insolvency defaults and material judgment defaults.  The Company is currently in compliance with all loan covenants.


As a fee in connection with the Credit Agreement, the Company issued warrants to Horizon and Oxford (the “Warrants”) to purchase the number of shares of the Company’s common stock equal to 3% of each loan amount divided by the exercise price, which was calculated as the average NASDAQ closing price of the Company’s common stock for the three days prior to the funding of the loan amount ($13.14 per share for the Term A Loan).  This resulted in 11,416 warrant shares issued in connection with the Term A Loan.  The Warrants issued in connection with the Term A Loan are immediately exercisable for cash or by net exercise and will expire seven years after their issuance, which is June 27, 2019.


The Company valued the Warrants using the Black-Scholes option pricing model and recorded $73,654 as deferred financing fees.  In calculating the value of the warrants, the Company assumed a volatility rate of 74.3%, risk free interest rate of 1.10%, an expected life of 3.5 years, a stock price equal to the closing price on the date of the Warrant and no expected forfeitures nor dividends. 


In connection with the Credit Agreement, the Company incurred cash and other expenses of $291,369 which were recorded as deferred financing fees.  These deferred financing fees are being amortized as interest expense over the life of the loan.  For the first nine months of 2013, $98,817 in deferred financing fees was amortized as interest expense.  Also, the Company paid $384,607 in interest expense on the Credit Agreement during this same period.


Following is a schedule of future principal payments due on the Credit Agreement:
