NOTE 5 — LOAN AND SECURITY AGREEMENT

On April 14, 2021, the Company entered into a $30.0 million Loan and Security Agreement (the “Loan Agreement”) with SLR Investment Corp. and certain other lenders (the “Lenders”). The Lenders agreed to loan up to $30.0 million in three tranches consisting of (i) a $15.0 million term A loan that was funded on April 14, 2021, (ii) term B and C loans for an aggregate of $15.0 million, which were subject to the Company’s ability to obtain prescribed amounts of financing and the achievement of certain clinical milestones. The Company did not achieve the initial clinical milestones by January 2022 and, accordingly, the term B and term C loans are no longer a source of liquidity. The term A loan has a maturity date of April 1, 2026 (the “Maturity Date”).

In addition, the Company’s cash and cash equivalents became subject to a blocked account control agreement (“BACA”) in favor of the Lenders whereby a cash balance of at least $5.0 million was required beginning on December 31, 2021. Accordingly, the Company has classified $5.0 million as a long-term restricted cash asset in the accompanying unaudited condensed consolidated balance sheet as of March 31, 2022. In the event of a default under the Loan Agreement, the BACA would enable the Lenders to prevent the release of funds from the Company’s cash accounts.

Outstanding borrowings under the Loan Agreement bear interest at a floating rate equal to (a) 8.75% per annum plus (b) the greater of (i) the rate per annum published by the Intercontinental Exchange Benchmark Administration Ltd. (“IEBA”) for a term of one month and (ii) 0.12% per annum. For the period from April 14, 2021 through February 28, 2022, the IEBA rate for a term of one month was approximately 0.12% per annum. For the period from February 28, 2022 through March 31, 2022, the IEBA rate for a term of one month was approximately 0.23% per annum. Therefore, the contractual rate was 8.98% and 8.87% as of March 31, 2022 and June 30, 2021, respectively. The Company is permitted to make interest-only payments on the term A loan through May 1, 2023. At the Company’s request, the interest-only period can be extended until May 1, 2024, provided that no event of default shall have occurred. The Company will be required to make monthly payments of principal and interest commencing at the end of the interest-only period.

The Company is obligated to pay the Lenders (i) a non-refundable facility fee in the amount of 1.00% of the term A loan that was funded (the “Facility Fee”), and (ii) a final fee equal to 4.75% of the aggregate amount of the term A loan that was funded (the “Final Fee”). As of March 31, 2022, the Company incurred debt discounts for an aggregate of $1.7 million that consisted of $0.4 million for financial advisory and legal fees, an aggregate of $0.9 million for the Facility Fee and the Final Fee, and an aggregate of $0.4 million as an exit fee as discussed below. The Final Fee is payable upon the earliest to occur of (i) the Maturity Date, (ii) the acceleration of the term loans, and (iii) the prepayment of the term loans. The total debt discount of $1.7 million related to the term A loan is being accreted to interest expense using the effective interest method whereby the effective interest rate amounted to 12.7% and 12.6% as of March 31, 2022 and June 30, 2021, respectively.

Concurrently with the execution of the Loan Agreement, the Company entered into an exit fee agreement (the “Exit Fee Agreement”) that provides for a fee of 4.00% of the funded principal balance of each term loan in the event certain transactions (defined as “Exit Events”) occur prior to April 13, 2031. Exit Events include, but are not limited to, sales of substantially all assets, certain mergers, change of control transactions, and issuances of common stock that result in new investors owning more than 35% of the Company’s shares. As of April 14, 2021, the Company allocated a portion of the proceeds from the term A loan to recognize a liability for the fair value of this embedded derivative for approximately $354,000. Fair value was determined based on the Company’s strategic corporate development plans and management has performed a detailed evaluation of the different types of Exit Events that could occur and using a discounted rate equivalent to the effective rate for the term A loan. Fair value of this embedded derivative is assessed at the end of each reporting period with changes in fair value recognized as a nonoperating gain or loss.

The Company has the option to prepay all, but not less than all, of the outstanding principal balance of the term loans. In the event of a voluntary or mandatory prepayment prior to the Maturity Date, the Company will incur a prepayment fee ranging from 1.00% to 3.00% of the outstanding principal balance.

The Company’s obligations under the Loan Agreement are secured by a first-priority security interest in substantially all the Company’s assets, including its intellectual property. This security interest will not be released until all obligations are repaid, including the requirement to pay an Exit Fee of $0.6 million for certain fundamental transactions that may occur through April 13, 2031. The Loan

Agreement contains customary representations, warranties and covenants and also includes customary events of default, including payment defaults, breaches of covenants, and a default upon the occurrence of a material adverse change affecting the Company. Upon the occurrence of an event of default, a default interest rate of an additional 5.00% per annum may be applied to the outstanding loan balance, and the Lenders may declare all outstanding obligations immediately due and payable and exercise all of their rights and remedies as set forth in the Loan Agreement.

As of March 31, 2022, the Company had outstanding contractual obligations under the Loan Agreement consisting of the principal balance of $15.0 million and the Final Fee of $0.7 million for a total of $15.7 million. After deducting the unaccreted discount of $1.4 million, the net carrying value was $14.3 million as of March 31, 2022. Future minimum principal payments and the net carrying value of the term A loan are as follows as of March 31, 2022 (in thousands):
