Initial PPA

On July 20, 2022, the Company entered into the Pre-Paid Advance Agreement (the "Initial PPA") with YA II PN, Ltd. ("Yorkville") pursuant to which the Company could request advances of up to $50.0 million in cash from Yorkville, with an aggregate limit of $300.0 million (the "Pre-Paid Advance"). Amounts outstanding under Pre-Paid Advances could be offset by the issuance of shares of Common Stock to Yorkville at a price per share calculated pursuant to the Initial PPA as the lower of 120.0% of the daily volume-weighted average price (“VWAP”) on Nasdaq as of the day immediately preceding the date a Pre-Paid Advance was made (“Fixed Price”) or 95.0% of the VWAP on Nasdaq as of the day immediately preceding the conversion date, which in no event would be less than $23.00 per share (“Floor Price”). The third Pre-Paid Advance (the "Third Pre-Paid Advance") amended the purchase price to be the lower of 110.0% of the VWAP on Nasdaq as of the day immediately preceding the date a Pre-Paid Advance was made (“Amended Fixed Price”) or 95.0% of the VWAP on Nasdaq during the five days immediately preceding the conversion date, which in no event would be less than $11.50 per share (“Amended Floor Price”). The Company's stockholders approved the Amended Floor Price, which was proposed and voted on at the special meeting of Company stockholders held on January 24, 2023. The Company's stockholders further approved the Second Amended Floor Price (as defined below), which was proposed and voted on at the special meeting of Company stockholders held on October 5, 2023. The issuance of the shares of Common Stock under the Initial PPA is subject to certain limitations, including that the aggregate number of shares of Common Stock issued pursuant to the Initial PPA (including the aggregation with the issuance of shares of Common Stock under Standby Equity Purchase Agreement entered into by the Company with Yorkville on May 10, 2022 (the “SEPA”), which was terminated effective August 26, 2022) cannot exceed 19.9% of the Company's outstanding shares of Common Stock as of May 10, 2022 ("PPA Exchange Cap"). The Company's stockholders approved the issuance of shares of the Company’s Common Stock in excess of the PPA Exchange Cap, which was proposed and voted on at the special meeting of Company stockholders held on January 24, 2023. Interest accrues on the outstanding balance of any Pre-Paid Advance at an annual rate equal to 5.0%, subject to an increase to 15.0% upon events of default described in the Initial PPA. Each Pre-Paid Advance has a maturity date of 15 months from the Pre-Paid Advance Date. Yorkville is not entitled to participate in any earnings distributions until a Pre-Paid Advance is offset with shares of Common Stock.

Between July 2022 and October 2022, Yorkville agreed to advance amounts to the Company on account of the first and second pre-paid advances (“Previous Pre-Paid Advances”) in accordance with the Initial PPA.

On December 31, 2022, the Company received an aggregate of $32.0 million on account of the fourth Pre-Paid Advance in accordance with the Initial PPA (the "Fourth Pre-Paid Advance"). In accordance with the second supplemental agreement, the Fourth Pre-Paid Advance may, at the sole option of Yorkville, be increased by up to an additional $8.5 million (the "YA PPA Option"). On January 13, 2023, Yorkville partially exercised their option, and increased their investment amount by $5.3 million, which resulted in net proceeds of $5.0 million, and was applied to the Fourth Pre-Paid Advance.

The Initial PPA provides that in respect of any Pre-Paid Advance, if the VWAP of shares of Common Stock is less than the Floor Price (as amended from time to time) for at least five trading days during a period of seven consecutive trading days or the Company has issued substantially all of the shares of Common Stock available under the PPA Exchange Cap, then the Company is required to make monthly cash payments of amounts outstanding under any Pre-Paid Advance beginning on the 10th calendar day and continuing on the same day of each successive calendar month until the entire amount of such Pre-Paid Advance balance has been paid or until the payment obligation ceases. Pursuant to the Initial PPA, the monthly payment obligation ceases if the PPA Exchange Cap no longer applies and the VWAP is greater than the Floor Price (as amended from time to time) for a period of five consecutive trading days, unless a subsequent triggering date occurs.
The Company, at its option, has the right, but not the obligation, to repay early in cash a portion or all amounts outstanding under any Pre-Paid Advance, provided that the VWAP of the Common Stock is less than the Fixed Price during a period of three consecutive trading days immediately prior to the date on which the Company delivers a notice to Yorkville of its intent and such notice is delivered at least ten trading days prior to the date on which the Company will make such payment. If elected, the early repayment amount is to include a 3.0% redemption premium (“Redemption Premium”). If any Pre-Paid Advances are outstanding and any event of default has occurred, the full amount outstanding under the Pre-Paid Advances plus the Redemption Premium, together with interest and other amounts owed in respect thereof, will become, at Yorkville’s election, immediately due and payable in cash.

Yorkville has the right and option (the “August Loan Option”) to purchase additional convertible debentures in an aggregate principal amount of up to $53.2 million. In conjunction with the August Initial Loan, the Company issued to Yorkville an initial warrant (the
“August Initial Warrant”) to purchase 2.2 million shares of Common Stock at an exercise price of $12.42 per share. Yorkville did not exercise the August Loan Option, as a result of which, the August Loan Option and the related August Option Warrant are no longer applicable.

On September 26, 2023, the Company entered into a Securities Purchase Agreement with Yorkville (the “September Convertible Debenture”, together with the August Convertible Debenture, collectively, the "YA Convertible Debentures"), receiving an aggregate of $15.0 million (the “September Initial Debenture”).

In conjunction with the September Convertible Debenture, the Company issued to Yorkville an initial warrant (the “September Initial Warrant”) to purchase 1.2 million shares of Common Stock at an exercise price of $12.42. If Yorkville exercises the September Loan Option, the Company will issue to Yorkville an additional warrant (the “September Option Warrant”) for a number of shares of Common Stock determined by dividing the principal amount so exercised (up to $30.0 million) by $12.42 per share.

As of January 19, 2024, the September Convertible Debentures was fully paid off through the issuance of 3.5 million shares of Common Stock to Yorkville, resulting in a loss on extinguishment of debt of $0.8 million. During the six months ended June 30, 2024, the Company incurred $0.1 million of interest expense.

Amounts outstanding in the YA Convertible Debentures could be offset by the issuance of shares of Common Stock to Yorkville at a price per share calculated at the lower of $11.50 (the "Note Fixed Price") or 95.0% of the lowest daily VWAP on Nasdaq as of the five immediately preceding the conversion date (“Variable Price”), which in no event would be less than $2.30 per share. The issuance of the shares of Common Stock under the YA Convertible Debentures are subject to certain limitations, including that the aggregate number of shares of Common Stock issued pursuant to the YA Convertible Debenture cannot exceed 4.1 million ("Note Exchange Cap"). With respect to the August Convertible Debenture, the Company's stockholders approved the issuance of shares of the Company’s Common Stock in excess of the Note Exchange Cap, which was proposed and voted on at the October Special Meeting.

Interest accrues on the outstanding balance of the August Convertible Debenture and the September Convertible Debenture at an annual rate equal to 3.0%, subject to an increase to 15.0% upon events of default described in their respective agreements.

The Company elected to account for the August Convertible Debenture and the September Convertible Debenture under the fair value option of accounting upon issuance. The proceeds were allocated to all freestanding instruments recorded at fair value.

The primary reason for electing the fair value option is for simplification of accounting for the YA Convertible Debentures at fair value in its entirety versus bifurcation of the embedded derivatives. The fair value was determined using a Monte Carlo valuation model.

The YA Convertible Debentures provides that if the VWAP of shares of Common Stock is less than the then-applicable floor price for at least five trading days during a period of seven consecutive trading days (“Trigger Date”) or the Company has issued substantially all of the shares of Common Stock available under the Note Exchange Cap, or the Company is unable to issue Common Stock to Yorkville which may be freely resold by Yorkville without any limitations or restrictions, including, without limitation, due to a stop order or suspension of the effectiveness of the Registration Statement, then the Company is required to make monthly cash payments of amounts outstanding under the YA Convertible Debentures beginning on the 10th Trading Day after the Trigger Date and continuing on the same day of each successive calendar month until the entire amount of the YA Convertible Debentures balance has been paid or until the payment obligation ceases. Pursuant to the YA Convertible Debenture, the monthly payment obligation ceases if the Exchange Cap no longer applies and the VWAP is greater than the Floor Price for a period of five consecutive trading days, unless a subsequent triggering date occurs.

The Company, at its option, has the right, but not the obligation, to repay early in cash a portion or all amounts outstanding under the YA Convertible Debentures, provided that the VWAP of the Common Stock is less than the Fixed Price during a period of three consecutive trading days immediately prior to the date on which the Company delivers a notice to Yorkville of its intent and such notice is delivered at least ten trading days prior to the date on which the Company will make such payment. If elected, the early repayment amount is to include a 5.0% redemption premium (“Redemption Premium”). If any event of default has occurred, the full amount outstanding under the Loan plus the
Redemption Premium, together with interest and other amounts owed in respect thereof, will become, at Yorkville’s election, immediately due and payable in cash.
