On February 29, 2016, the Company closed on new financings with MidCap and paid off all remaining amounts due to the Company's previous lender Wells Fargo. Additionally, on February 29, 2016, the Company converted certain amounts payable to related parties into unsecured term notes payable to the same related parties as more fully described in Note 6 – Related Party Transactions. On March 31, 2017, the Company entered into an amendment to increase the line of credit, subject to the satisfaction of certain borrowing base restrictions (which have been satisfied), and extend the maturity date more fully described below. On June 23, 2017, in connection with the purchase of equipment to be used in the operation of the Company's business, the Company issued notes totaling $129.0 thousand principal amount due to a related party. See Note 6 – Related Party Transactions.

On February 29, 2016, the Company entered into the 2016 Loan, which, as initially entered into, provided a $6.0 million senior, secured asset-based line of credit with MidCap. The Company could borrow up to the sum of (a) 85% of the value of its eligible domestic accounts receivable; (b) the lesser of (i) $2.5 million and (ii) 75% of the net orderly liquidation value of eligible inventory; and (c) the lesser of (i) $500,000 and (ii) 40% of appraised net forced liquidation value of eligible fixed assets (the "Equipment Sublimit"). The Equipment Sublimit amortizes monthly on a straight line basis over sixty (60) months with no reduction to the overall line of credit availability. As described below, the 2016 Loan was amended on March 31, 2017.

Proceeds from this loan were used to pay transaction expenses, pay off and close the remaining balance on the Wells Fargo revolving line of credit and fund working capital requirements.

The interest rate on the 2016 Loan is equal to the prime rate (4.75% as of March 31, 2018) plus 250 basis points (2.50%). In the Event of a Default (as defined in the 2016 Loan Agreement), the interest rate will increase by 300 basis points (3.00%). The 2016 Loan also has a monthly collateral-monitoring fee equal to 27.5 basis points (0.275%) of the average daily balance outstanding, an annual facility fee of 100 basis points (1.00%) and an unused line fee equal to an annual rate of 50 basis points (0.50%) of the average undrawn portion of the 2016 Loan.

The 2016 Loan has a maturity date of February 28, 2020 based on the amendment described below. The borrowings under the revolving credit agreement are classified as short-term obligations under GAAP as the agreement with MidCap contains a subjective acceleration clause and requires the Company to maintain a lockbox arrangement with the lender.

The Company was subject to a prepayment fee of $120.0 thousand if the 2016 Loan was terminated or prepaid prior to the one year anniversary of the loan. The Company is subject to a prepayment fee of $60.0 thousand if the 2016 Loan is terminated or prepaid subsequent to the one year anniversary of the loan, but prior to the maturity date.

The 2016 Loan Agreement contains a minimum line availability covenant equal to $350.0 thousand. This covenant may be replaced by a Fixed Charge Coverage Ratio ("FCCR") covenant once the Company has achieved a FCCR of 1.0x on an annualized basis.

The Company granted MidCap a first priority security interest in all of the assets of ISA pursuant to the terms of a Security Agreement.

The Company is allowed to sell or refinance up to $3.0 million in fair market value of real property provided (i) the proceeds from such refinance or sale remain with the Company; and (ii) no event of default exists at the time of such refinance or sale.

On March 31, 2017, the Company and each of its wholly-owned subsidiaries entered into an amendment to the 2016 Loan with MidCap ("First Amendment"). The First Amendment increased the line of credit from $6.0 million to $8.0 million and extended the maturity date to February 28, 2020. As amended, the line of credit permits the Company to borrow an amount under the 2016 Loan equal to the lesser of (A) $8.0 million; and (B)(i) 85% of the value of the Company’s eligible domestic accounts receivable, plus (ii) the lesser of (x) $2.5 million and (y) 75% of the net orderly liquidation value of eligible inventory, plus (iii) the lesser of (x) $400,000 and (y) 40% of appraised net forced liquidation value of eligible fixed assets, plus (iv) the lesser of (x) $1.75 million and (y) 45% of the appraised value of certain properties owned by the Company (subject to MidCap's receipt of any third-party or internal approvals it may require in its discretion), minus (v) any amount which MidCap may require from time to time, pursuant to terms of the agreement, in order to secure amounts owed to MidCap under the agreement. The First Amendment contains a minimum line availability covenant equal to $350.0 thousand, the same as the original 2016 Loan. This covenant may be replaced by a FCCR covenant once the Company has achieved an FCCR of 1.1x on an annualized basis. The Company paid underwriting fees of $20.0 thousand at closing.

On April 26, 2017, certain borrowing base restrictions were satisfied with MidCap which resulted in an increase in availability of $1.75 million.
