 5.       Note Payable

On September 30, 2014, we entered into a loan and security agreement, as amended on February 19, 2015, pursuant to which we received a term loan in the amount of $5 million, funded in 3 tranches. The first tranche of $2.5 million was provided to us on October 1, 2014. The proceeds from the first tranche were used to repay the existing loan with a financial institution which totaled approximately $1,631,000 and the balance was used for general working capital purposes and capital expenditures. The first tranche borrowing is repayable in interest only payments until November 1, 2015 and then 30 equal installments of principal and interest at a rate of 5.25% per annum. The second tranche of the term loan is equal to $1.5 million, of which $500,000 was provided to us on February 19, 2015 and an additional $1 million was subject to (i) evidence acceptable to the lender of at least 50% enrollment in the Company’s randomized, blinded and sham-controlled clinical trial in Europe and Canada (the “OUS Clinical Trial”) no later than March 9, 2015, which has been satisfied, and (ii) when documentation or other evidence acceptable to the lender of a prospective equity financing was provided. On March 16, 2015, we received an additional $500,000 in connection with a drawdown of funds from the second tranche, for a total of $1,000,000 received under the second tranche as of March 31, 2015. The second tranche borrowings in February and March 2015 are repayable in interest only payments until March 1, 2016 and then 30 equal installments of principal and interest at a rate of 5.00% and 5.06% per annum, respectively. The Company may receive up to $1 million in connection with the third tranche at any time during the period in which it has provided evidence to lender of positive 3-month interim results with respect to the OUS Clinical Trial until June 30, 2015. The proceeds from the second and third tranches will be used for general working capital purposes and capital expenditures. As of March 31, 2015 and December 31, 2014, the note payable had an outstanding balance of $3,500,000 and $2,500,000, respectively, which is recorded as a current liability on the condensed consolidated balance sheets. All borrowings under the agreement are collateralized by substantially all of the Company’s assets, including intellectual property.

The loan and security agreement also requires that the Company comply with certain financial and other covenants for borrowings to be permitted. The terms of the loan require that the Company meet certain financial covenants and milestones in connection with the OUS Clinical Trial, including but not limited to, (a) full enrollment as of March 31, 2015, (b) positive 3-month interim data as of April 15, 2015, subject to postponement until June 30, 2015 by the lender upon achievement of certain other milestones under the loan, as amended, and (c) positive results from the trial as of January 31, 2016. As of March 31, 2015, full enrollment of the OUS Clinical Trial has been achieved. As of March 31, 2015 the Company was in compliance with all covenants of the loan agreement.

In connection with the loan and security agreement, the Company issued a 10-year warrant to the lender for the purchase of 471,698 shares of the Company’s common stock at $0.53 per share. In connection with the loan amendment, the Company also amended the terms of the warrant issued to the lender to provide for an automatic increase of the number of shares the lender may acquire in the event the Company fails to meet certain covenants (see Note 7).

The loan and security agreement with the financial institution contains a material adverse change clause, as defined in the agreement, which would result in an event of default if the lender deems a material adverse change to have occurred to the Company’s business. The continuing liquidity issues the Company faces could be construed by the note holder as a material adverse change which could trigger an acceleration of all of the outstanding debt. As such, the Company has classified all of its outstanding debt balance as a current liability as of March 31, 2015 and December 31, 2014.

As of March 31, 2015, future minimum payments under the note payable are as follows (in thousands):
