Loans and Security Agreement

Loan and Security Agreement

On March 16, 2020, the Company and Rockwell Transportation, Inc., as Borrowers, entered into a Loan and Security Agreement (the "Loan Agreement") with Innovatus Life Sciences Lending Fund I, LP ("Innovatus"), as collateral agent and the lenders party thereto, pursuant to which Innovatus, as a lender, agreed to make certain term loans to the Company in the aggregate principal amount of up to $35.0 million (the "Term Loans"). Funding of the first $22.5 million tranche was completed on March 16, 2020. The Company is no longer eligible to draw on a second tranche of $5.0 million or a third tranche of $7.5 million, which were tied to the achievement of certain milestones by a specific date. Net draw down proceeds were $21.2 million with closing costs of $1.3 million.

In connection with each funding of the Term Loans, the Company was required to issue to Innovatus a warrant (the “Warrants”) to purchase a number of shares of the Company’s common stock equal to 3.5% of the principal amount of the relevant Term Loan funded divided by the exercise price, which was based on the lower of (i) the volume weighted average closing price of the Company’s stock for the 5-trading day period ending on the last trading day immediately preceding the execution of the Loan Agreement or (ii) the closing price on the last trading day immediately preceding the execution of the Loan Agreement (or for the second and third tranches only at the lower of (i) $18.15 per share or (ii) the volume weighted average closing price of the Company’s stock for the 5-trading day period ending on the last trading day immediately preceding the relevant Term Loan funding). The Warrants may be exercised on a cashless basis and are immediately exercisable through the seventh anniversary of the applicable funding date. The number of shares of common stock for which each Warrant is exercisable and the associated exercise price are subject to certain proportional adjustments as set forth in such Warrant. In connection with the first tranche of the Term Loans, the Company issued a Warrant to Innovatus, exercisable for an aggregate of 43,388 shares of the Company’s common stock at an exercise price of $18.15 per share. The Company evaluated the warrant under ASC 470, Debt, and recognized an additional debt discount of approximately $0.5 million based on the relative fair value of the base instruments and warrants. The Company calculated the fair value of the warrant using the Black-Scholes model.

The Company is entitled to make interest-only payments for thirty months, or up to thirty-six months if certain conditions are met. The Term Loans will mature on March 16, 2025, and will bear interest at the greater of (i) Prime Rate (as defined in the Loan Agreement) and (ii) 4.75%, plus 4.00% with an initial interest rate of 8.75% per annum and an effective interest rate of 10.9%. The Company has the option, under certain circumstances, to add 1.00% of such interest rate amount to the then outstanding principal balance in lieu of paying such amount in cash. For the three months ended June 30, 2023 and 2022, interest expense amounted to $0.3 million and $0.4 million, respectively. For the six months ended June 30, 2023 and 2022, interest expense amounted to $0.6 million and $0.8 million, respectively.

The Loan Agreement is secured by all assets of the Company and Rockwell Transportation, Inc. Proceeds are used for working capital purposes. The Loan Agreement contained customary representations and warranties and covenants, subject to customary carve outs, and included financial covenants related to liquidity and trailing twelve months sales of Triferic, with the latter beginning with the period ending December 31, 2020.

In September 2021, the Company entered into an amendment to the Loan Agreement in which the Company, in exchange for Innovatus lowering the sales covenants, agreed to (i) prepay an aggregate principal amount of $7.5 million in ten installments commencing on December 1, 2021; (ii) pay an additional prepayment premium of 5% on prepaid amounts if the Company elects to prepay all outstanding Term Loans on or before September 24, 2023 and (iii) maintain minimum liquidity of no less than $5.0 million if the aggregate principal amount of Term Loans is greater than $15 million pursuant to the liquidity covenant in the Loan Agreement.

On November 10, 2022, the Company entered into a Second Amendment to the Loan and Security Agreement (the “Second Amendment”) dated as of November 14, 2022 with Innovatus, which amended the Loan Agreement. Pursuant to the Second Amendment, the Company (i) prepaid an aggregate principal amount of $5.0 million in Term Loans in one installment on November 14, 2022; (ii) shall pay interest only payments until September 2023 at which time will resume scheduled debt payments. Additionally, the financial covenants related to the trailing twelve months sales of Triferic was replaced with a trailing 6 months revenue of our concentrates products beginning with the period ending September 30, 2022. The Company cannot assure that it can maintain compliance with the covenants under our Loan Agreement, which may result in an event of default. The Company's ability to comply with these covenants may be adversely affected by events beyond its control. If the Company is unable to comply with the covenants under the Loan Agreement, it would pursue all available cure options in order to regain compliance. However, the Company may not be able to mutually agree with Innovatus on appropriate remedies to

cure a future breach of a covenant, which could give rise to an event of default. If the Company is unable to avoid an event of default, any required repayments could have an adverse effect on its liquidity.

As of June 30, 2023, the Company was in compliance with all covenants under the Loan Agreement.

As of June 30, 2023, the outstanding balance of the Term Loan was $9.4 million, net of unamortized issuance costs and discount of $0.6 million.
