Item 1.01 Entry Into Material Definitive Agreement.

We previously entered into an Amended and Restated Term Loan Agreement with Capital Royalty Partners II, L.P. and its affiliate funds (“Capital Royalty Partners”), which has since been amended by Consent and Amendment Agreement, dated June 20, 2014, Omnibus Amendment Agreement No. 2, dated February 23, 2015 and Amendment No. 3 to Term Loan Agreement, dated January 8, 2016 (as so amended, the “Term Loan Agreement”).

On March 7, 2017, we entered into Waiver and Amendment No. 4 to the Term Loan Agreement (the “Fourth Amendment”). The Fourth Amendment includes a limited waiver of a potential event of default that could have resulted from the explanatory paragraph in the audit report of our independent registered public accounting firm contained in our financial statements for the year ended December 31, 2016. In consideration for the waiver, we agreed to: (i) issue Capital Royalty Partners ten-year warrants to purchase an aggregate of 1,937,890 shares of our common stock at an exercise price equal to $2.35 per share, the closing price of our common stock on the NASDAQ Global Market on the date of the Fourth Amendment (the “Warrants”), (ii) increase our minimum cash balance requirement under the Term Loan Agreement from $2.0 million to $10.0 million, (iii) provide Capital Royalty Partners the same information we make available to our board of directors, subject to limited exceptions, and (iv) not incur additional third party indebtedness secured solely by accounts receivable, inventory and cash.  In addition, the Fourth Amendment includes a covenant requiring us to complete a financing in which our gross proceeds from the sale of equity securities is at least $30.0 million, no later than January 15, 2018.

Furthermore, in connection with Amendment No. 3 to the Term Loan Agreement (the “Third Amendment”), we previously agreed to pay, on the earlier of (i) the maturity date of the Term Loan Agreement, which is March 31, 2020, (ii) the date that the loan under the Term Loan Agreement becomes due, and (iii) the date on which we make a voluntary pre-payment of the loan, a financing fee equal to 3.0% of the sum of (x) the aggregate amount drawn under the Third Amendment, and (y) any PIK Loans (as defined in the Term Loan Agreement) issued in relation to the Third Amendment (collectively, the “Back End Financing Fee”). Pursuant to the Fourth Amendment, we have agreed to increase the Back End Financing Fee to 5.0% of the entire aggregate principal amount of borrowings outstanding, including total PIK Loans issued, under the Term Loan Agreement, which was $81.1 million as of December 31, 2016.  The Back End Financing Fee is payable at maturity of our loans and on the principal amount of any loans for which we make an optional prepayment, and may be payable in connection with asset sales not permitted under the Term Loan Agreement or in connection with a change of control.  

The foregoing descriptions of the Fourth Amendment and the Warrants do not purport to be complete and are qualified in their entirety by copies of such documents, which will be filed as exhibits to our next periodic report.
