On February 13, 2019 (the “CRG Closing Date”), the Company entered into the CRG Loan Agreement among the Company, as borrower, CRG Servicing LLC, as administrative agent and collateral agent (the “Agent”), and the lenders party thereto from time to time (the “Lenders”), providing for a senior secured term loan of up to $60 million (the “CRG Loan”). On the CRG Closing Date, $35 million of the CRG Loan was advanced (the “CRG Initial Advance”). The Company utilized the proceeds from the CRG Initial Advance for the repayment in full of all outstanding obligations under its prior credit agreement (the “SWK Credit Agreement”) with SWK Funding LLC (“SWK”). In April 2019, the Company exercised its option to borrow an additional $15 million of the CRG Loan (the “CRG Second Advance”). The Company did not draw any additional funds under the CRG Loan by the final draw deadline of March 31, 2020.

The CRG Loan is due and payable on December 31, 2023 (the “Maturity Date”). The CRG Loan bears interest at a fixed rate of 12.5% per annum payable in arrears on the last business day of each calendar quarter. The Company is required to make quarterly, interest only payments until the Maturity Date. So long as no default has occurred and is continuing, the Company may elect on each applicable interest payment date to pay 2.5% of the 12.5% per annum interest as Paid In-Kind (“PIK”), whereby such PIK amount would be added to the aggregate principal amount and accrue interest at 12.5% per annum. Through March 31, 2020, total PIK amounts of $323,000 have been added to the principal balance of the CRG Loan. In addition, the Company is required to pay an upfront fee of 1.5% of amounts borrowed under the CRG Loan (excluding any paid-in-kind amounts), which is payable as amounts are advanced under the CRG Loan. The Company will also be required to pay an exit fee equal to 6% of (i) the aggregate principal amounts advanced and (ii) PIK amounts issued, under the CRG Loan Agreement. In connection with the CRG Initial Advance, a 1.5% financing fee of $525,000 and an expense reimbursement of $350,000 were deducted from the net borrowing proceeds. In connection with the CRG Second Advance, a 1.5% financing fee of $225,000 was deducted from the net borrowing proceeds.

Upon the occurrence of a bankruptcy-related event of default, all amounts outstanding with respect to the CRG Loan become due and payable immediately, and upon the occurrence of any other Event of Default (as defined in the CRG Loan Agreement), all or any amounts outstanding with respect to the CRG Loan may become due and payable upon request of the Agent or majority Lenders. Subject to certain exceptions, the Company is required to make mandatory prepayments of the CRG Loan with the proceeds of assets sales and in the event of a change of control of the Company. In addition, the Company may make a voluntary prepayment of the CRG Loan, in whole or in part, at any time. All mandatory and voluntary prepayments of the CRG Loan are subject to the payment of prepayment premiums as follows: (i) if prepayment occurs after December 31, 2019 and on or prior to December 31, 2020, 5% of the aggregate outstanding principal amount of the CRG Loan being prepaid and (ii) if prepayment occurs after December 31, 2020 and on or prior to December 31, 2021, an amount equal to 3% of the aggregate outstanding principal amount of the CRG Loan being prepaid. No prepayment premium is due on any principal prepaid after December 31, 2021. Certain of the Company’s existing and future subsidiaries are guaranteeing the obligations of the Company under the CRG Loan Agreement. The obligations of the Company under the CRG Loan Agreement and the guarantee of such obligations are secured by a pledge of substantially all of the Company’s and the guarantors’ assets.

The CRG Loan Agreement contains affirmative and negative covenants customary for financings of this type, including limitations on our and our subsidiaries’ abilities, among other things, to incur additional debt, grant or permit additional liens, make investments and acquisitions, merge or consolidate with others, dispose of assets, pay dividends and distributions and enter into affiliate transactions, in each case, subject to certain exceptions. In addition, the CRG Loan Agreement contains the following financial covenants requiring the Company and the Guarantors to maintain:

•

liquidity in an amount which shall exceed the greater of (i) $5 million and (ii) to the extent the Company has incurred certain permitted debt, the minimum cash balance, if any, required of the Company by the creditors of such permitted debt; and

•

annual minimum product revenue from YUTIQ and DEXYCU: (i) for the twelve-month period beginning on January 1, 2019 and ending on December 31, 2019, of at least $15 million, (ii) for the twelve-month period beginning on January 1, 2020 and ending on December 31, 2020, of at least $45 million, (iii) for the twelve-month period beginning on January 1, 2021 and ending on December 31, 2021, of at least $80 million and (iv) for the twelve-month period beginning on January 1, 2022 and ending on December 31, 2022, of at least $90 million.

In November 2019, CRG waived the financial covenant associated with the Company’s revenue derived from sales of its products, DEXYCU and YUTIQ, for the twelve-month period ending December 31, 2019.

The total debt discount related to the CRG Loan was approximately $4.3 million and consisted of (i) the accrual of a $3.0 million exit fee; (ii) the $750,000 upfront fee; and (iii) $591,000 of legal and other transaction costs. This amount is being amortized as additional interest expense over the term of the CRG Loan using the effective interest rate method.

Amortization of debt discount under the CRG Loan totaled $171,000 and $56,000 for the three months ended March 31, 2020 and 2019, respectively.

On March 28, 2018(the “SWK Closing Date”), the Company entered into the SWK Credit Agreement among the Company, as borrower, SWK, as agent, and the lenders party thereto from time to time, providing for a senior secured term loan of up to $20 million (the “SWK Loan”). On the SWK Closing Date, $15 million of the SWK Loan was advanced (the “SWK Initial Advance”). The remaining $5 million of the SWK Loan was advanced on June 26, 2018 (the “SWK Additional Advance”).

In connection with the SWK Loan, the Company issued a warrant (the “SWK Warrant”) to the Agent to purchase (a) 409,091 shares of Common Stock (the “Initial Advance Warrant Shares”) at an exercise price of $1.10 per share and (b) 77,721 shares of Common Stock (the “Additional Advance Warrant Shares”) at an exercise price of $1.93 per share (see Note 10). The SWK Warrant is exercisable (i) with respect to the Initial Advance Warrant Shares, any time on or after the SWK Closing Date until the close of business on the 7-year anniversary of the SWK Initial Advance and (ii) with respect to the Additional Advance Warrant Shares, any time on or after the closing of the SWK Additional Advance until the close of business on the 7-year anniversary of the SWK Additional Advance. The Agent may exercise the SWK Warrant on a cashless basis at any time. In the event the Agent exercises the SWK Warrant on a cashless basis, the Company will not receive any proceeds.

The Additional Advance Warrant Shares were recorded as a liability at the Closing Date and were remeasured at fair value at each reporting period until the date of the SWK Additional Advance. The aggregate fair value of the Additional Advance Warrant Shares at the Closing Date was $69,000. The Initial Advance Warrant Shares were recorded as equity on the Company’s balance sheet at their relative fair value of $284,000. The remaining $14.6 million of the proceeds received were allocated to the SWK Initial Advance term loan. Upon the closing of the SWK Additional Advance in June 2018, the Additional Advance Warrant Shares were re-valued at $87,000 and reclassified to equity.

The total debt discount related to the SWK Initial Advance was $2.1 million and was comprised of (1) $1.8 million, which included a 1.5% upfront fee, a 6% exit fee (the “Exit Fee”) and legal and other transaction costs, which were ratably allocated to each of the two tranches of the SWK Loan based upon the total principal amount available to the Company under each tranche and (2) $353,000 related to the aggregate fair value of the Initial Advance Warrant Shares and the Additional Advance Warrant Shares. This amount was being amortized as additional interest expense over the term of the SWK Loan using the effective interest rate method.

The total debt issue costs related to the SWK Additional Advance was $299,000 and was comprised of the allocated portions of the 1.5% upfront fee and the Exit Fee. This amount was recorded as a prepaid expense to be amortized ratably from the SWK Closing Date through December 31, 2018. Through the date of the SWK Additional Advance, $97,000 was amortized and the remaining balance of $202,000 was reclassified to debt discount in June 2018. Together with the 6% Exit Fee on the SWK Additional Advance and other transaction costs, total debt discount of $652,000 associated with the SWK Additional Advance was to be amortized over the remaining life of the SWK Additional Advance portion of the SWK Loan using the effective interest rate method.

The SWK Loan was originally scheduled to mature on March 27, 2023 and bore interest at a per annum rate of the three-month LIBOR rate (subject to a 1.5% floor) plus 10.50%. On February 13, 2019, the Company repaid the SWK Loan in connection with the consummation of the CRG Loan Agreement. In addition to repayment of the $20 million principal balance, the Company paid (i) a $1.2 million prepayment penalty, (ii) the $1.2 million Exit Fee, (iii) accrued and unpaid interest of $664,000 through that date and (iv) an additional make-whole interest payment of $306,000 covering the additional period through what would have been the first anniversary of the SWK Loan. In connection with the prepayment of the SWK Loan, the Company recorded a loss on extinguishment of debt of $3.8 million in the three months ended March 31, 2019. In addition to the prepayment penalty and make-whole interest payment amounts, the loss on extinguishment of debt included the write-off of the remaining balance of unamortized debt discount of approximately $2.3 million.

Amortization of debt discount under the SWK Loan totaled $84,000 in the first quarter of 2019 through the SWK loan extinguishment date.
