7. Oxford Finance Loan Agreement

On February 12, 2020, the Company entered into a Loan and Security Agreement (as subsequently amended, the “Loan Agreement”) with Oxford Finance LLC (the “Lender”). Pursuant to the terms of an amendment dated May 9, 2024 (the “Fourth Loan Amendment”), the Loan Agreement was modified to increase the aggregate amount of term loans available to the Company from $60.0 million to $100.0 million. A $20.0 million term loan was funded on February 12, 2020 (Term A) and another $20.0 million term loan was funded on December 23, 2020 (Term B). Two additional $20.0 million term loans (Term C and Term D) will become available upon achievement of certain clinical development, regulatory and equity-raising milestones, and another $20.0 million term loan (Term E) remains available solely at the discretion of the Lender.

The floating annual rate for each term loan is equal to the greater of (i) 7.75% and (ii) the sum of (a) the 1-month CME Term SOFR reference rate, (b) 0.10%, and (c) 5.98%. Pursuant to the terms of the Fourth Loan Amendment, the Lender agreed to extend the interest-only period from September 1, 2024 to November 1, 2025, with further extensions to as late as November 1, 2026 upon the achievement of certain milestones and the payment of certain fees, and to provide for the repayment of the aggregate outstanding principal balance of the term loan in monthly installments starting on November 1, 2025 through February 1, 2028 (the “Maturity Date”), subject to the potential further extension of the interest-only period.

The Company paid a facility fee of $0.1 million upon the issuance of the Term A loan, paid a facility fee of $75,000 upon the issuance of the Term B loan, and must pay a $50,000 facility fee if and when each of the Term C loan, the Term D loan, and the Term E loan is issued. In connection with prior extensions of the interest-only period, the Company paid fees of $300,000 in September 2022 and agreed to pay fees of $300,000 upon the first to occur of the Maturity Date or the acceleration or prepayment of any term loan. In connection with the Fourth Loan Amendment, the Company agreed to pay an additional fee of $1,050,000 upon the first to occur of the Maturity Date or the acceleration or prepayment of any term loan. The Company is required to make a final payment equal to 5.00% of the amount of the term loan drawn payable on the earlier of (i) the prepayment of the term loan or (ii) the Maturity Date. At the Company’s option, the Company may elect to prepay the loans subject to a prepayment fee equal to the following percentage of the principal amount being prepaid: 2% if an advance is prepaid during the first 12 months following the applicable advance date, 1% if an advance is prepaid after 12 months but prior to 24 months following the applicable advance date, and 0.5% if an advance is prepaid any time after 24 months following the applicable advance date but prior to the Maturity Date.

In connection with the Loan Agreement, the Company granted the Lender a security interest in all of the Company’s personal property now owned or hereafter acquired, excluding intellectual property (but including the right to payments and proceeds of intellectual property), and a negative pledge on intellectual property. The Loan Agreement also contains certain events of default, representations, warranties and covenants of the Company. In consideration of the Fourth Loan Amendment, the Company has agreed to, among other things, certain cash covenants, which requires an unrestricted cash balance in an aggregate amount of not less than (i) for May 31, 2024 and at all times thereafter through and including January 31, 2025, seventy-five percent (75.00%) of the aggregate principal amount of the outstanding obligations, and (ii) for February 1, 2025 and at all times thereafter through and including May 31, 2026, one hundred twenty percent (120.00%) of the aggregate principal amount of the outstanding obligations, and revenue performance covenants, and that the failure to satisfy the primary endpoint for the SELECT-MDS-1 trial, the termination of the Company’s SELECT-MDS-1 trial for safety reasons, or the failure to obtain United States Food and Drug Administration (“FDA”) approval for tamibarotene for the treatment of newly diagnosed HR-MDS patients with RARA overexpression by May 31, 2026, would each constitute events of default under the Loan Agreement. In addition, upon drawing any further loans under the Loan Agreement the Company has agreed to grant the Lender, to the extent permitted under existing agreements and applicable law, a security interest in all intellectual property owned by the Company. As of June 30, 2024, the Company was in compliance with all covenants under the Loan Agreement.

In connection with the issuance of the Term A loan, the Company issued the Lender warrants to purchase 2,754 shares of the Company’s common stock at an exercise price per share of $72.60 in February 2020. In connection with

the issuance of the Term B loan, the Company issued the Lender warrants to purchase 1,738 shares of the Company’s common stock at an exercise price of $115.00 per share in December 2020 (collectively, the “Oxford Warrants”). The Oxford Warrants are exercisable within five years from the respective dates of issuance.

The Oxford Warrants are classified as a component of permanent equity because they are freestanding financial instruments that are legally detachable and separately exercisable from the shares of common stock with which they were issued, are immediately exercisable, do not embody an obligation for the Company to repurchase its shares, and permit the holders to receive a fixed number of shares of common stock upon exercise. In addition, the Oxford Warrants do not provide any guarantee of value or return.
