NOTE 8 — BORROWING ARRANGEMENTS AND DEBT EXTINGUISHMENT

K2 HealthVentures Loan and Security Agreement

In May 2020, the Company entered into a Loan and Security Agreement with K2HV (the “K2 Loan and Security Agreement”) in the amount of $45.0 million. The K2 Loan and Security Agreement was drawable in three tranches and the Company had drawn down $35.0 million with the remaining tranche of $10.0 million having lapsed as of December 31, 2021. Pursuant to the terms of the K2 Loan and Security Agreement, the principal accrued interest at an

annual rate equal to the greater of 8.45 % or the sum of the Prime Rate plus 5.2%. In April 2022, the K2 Loan and Security Agreement was amended in exchange for a $0.3 million amendment fee so that (i) payments would be interest only until the loan’s maturity date of June 1, 2024, and (ii) the Financial Covenant would apply for the entire term of the K2 Loan and Security Agreement. This amendment resulted in a debt modification with the $0.3 million amendment fee recorded as a debt discount.

On June 16, 2023, the Company entered into the CVR Agreement with K2HV to fully discharge and satisfy the Company’s outstanding loan obligations under the K2 Loan and Security Agreement, and to terminate the K2 Loan and Security Agreement, in exchange for an aggregate repayment in cash of $27.5 million, the granting of a contingent value right to K2HV, and the issuance of a warrant to purchase shares of common stock to K2HV’s affiliated holder. These contingent value rights require payments to K2HV if certain Contingent Payment Events, as defined in the CVR Agreement, occur, or if there is an Acceleration Event, as defined in the CVR Agreement. The payment due upon any Contingent Payment Event or an Acceleration Event is capped at an amount (the “Remaining Value”) which is initially $10,303,646, which amount, to the extent not repaid is subject to escalating multipliers which increases from the closing date by multiplying the Remaining Value by a multiplier ranging between 1.0 at closing to 2.5x for any Remaining Value not yet paid as of September 16, 2024, resulting in a potential maximum payment obligation of $25,759,115. In addition, upon a Change in Control, as defined in the CVR Agreement, the Company is required to pay an additional payment of $2,500,000.

For Contingent Payment Events, the Company must pay K2HV either a specified percentage of the proceeds received, up to an amount equaling the applicable Remaining Value, 50% of such Remaining Value, or 100% of the Remaining Value, depending on the Contingent Payment Event which occurred. Upon the occurrence and continuation of any Acceleration Event, the applicable Remaining Value shall, at the election of K2HV, be due and payable in full. The Company may at any time elect to repay some or all of the Remaining Value without penalty. In lieu of a portion of these contingent value rights, K2HV may convert up to $3,000,000 of the Remaining Value into an aggregate of 408,267 shares of common stock, subject to adjustment for any stock splits and similar events so long as the number of shares of common stock underlying such conversion right, together with the shares of common stock underlying the warrants described below, do not exceed 19.99% of the number of shares of common stock outstanding immediate prior to the execution of the CVR Agreement.

In satisfaction of its obligations to issue the warrant to K2HV’s affiliated holder pursuant to the CVR Agreement, the Company issued a warrant to purchase up to 340,222 shares of the Company’s common stock at an exercise price of $5.8785 per share. The warrant has a term of 10 years. To protect its interest in any potential payment of the Remaining Value, K2HV has a security interest in, subject to certain limited exceptions, all assets (including intellectual property) of the Company. Further, the Company may not (i) incur any indebtedness for borrowed money that is structured as senior or pari passu to K2HV’s outstanding contingent payments without K2HV’s consent or (ii) permit any other liens (other than customary permitted liens) on this collateral without K2HV’s consent.

In accordance with ASC Topic 740-50, “Debt – Modifications and Extinguishments,” the transaction noted above was determined to be an extinguishment of the existing long-term debt. As a result, the Company recorded a gain on the extinguishment of long-term debt in the amount of $1.8 million in the line item “Gain on the extinguishment of debt” in the condensed consolidated statement of operations.
