MidCap Facility Agreement

The Company’s Amended Credit Facility with MidCap provides for a revolving credit commitment up to $22.5 million and provided for a term loan commitment up to $5 million. As of September 30, 2018, $9.5 million was outstanding under the revolving line of credit and the term loan was paid in full.

The revolving line of credit interest accrues at London Interbank Offered Rate (“LIBOR”) plus 6.0%, reset monthly. At September 30, 2018, the revolving line of credit carried an interest rate of 8.10%, with interest payable monthly. The borrowing base is determined based on the value of domestic eligible accounts receivable. As collateral for the Amended Credit Facility, MidCap has a first lien security interest in accounts receivable and a second lien on substantially all other assets.

At September 30, 2018, $1.1 million remains as unamortized debt discount related to the Amended Credit Facility on the condensed consolidated balance sheet, which will be amortized over the remaining term of the Amended Credit Facility.

The Amended Credit Facility also includes several event of default provisions, such as payment default, insolvency conditions and a material adverse effect clause, which could cause interest to be charged at a rate which is up to five percentage points above the rate effective immediately before the event of default or result in MidCap’s right to declare all outstanding obligations immediately due and payable.

On March 8, 2018, the Company entered into a Seventh Amendment to the Amended Credit Facility to extend the date that the financial covenants of the Amended Credit Facility are effective from April 2018 to April 2019, and established a minimum liquidity covenant of $5.0 million through March 2019. The Company was in compliance with the covenants under the Amended Credit Facility at September 30, 2018. On November 6, 2018, the Company entered into the Eighth Amendment to the MidCap Facility to extend the date that the financial covenants of the MidCap Facility are effective from April 2019 to April 2020, and extended the minimum liquidity covenant through March 2020.
