Item 4 is hereby amended and supplemented as follows: On January 14, 2025, BEP Special Situations IV LLC ("BEP SS IV") purchased $2,500,000 in aggregate principal amount of additional senior secured convertible notes (the "Additional Convertible Notes") pursuant to that certain Amendment No. 4 to the Amended and Restated Note Purchase Agreement, dated January 14, 2025 (the "NPA Fourth Amendment"), by and among the Issuer, Ascend Global Investment Fund SPC for and on behalf of Strategic SP ("Ascend"), BEP SS IV and the other parties thereto. The terms of the Additional Convertible Notes are substantially similar to the Convertible Notes (together with the Additional Convertible Notes, the "Notes"). All or any portion of the Notes may be converted at BEP SS IV's election at any time prior to the close of business on the business day immediately preceding August 15, 2028. The 12,161,865 and 40,947,329 shares of Common Stock reported as underlying the Additional Convertible Notes and the Convertible Notes, respectively, reflect the maximum number of shares of Common Stock BEP SS IV would receive assuming the Issuer pays all accrued interest in kind until maturity. In addition, on January 14, 2025, in connection with certain restructuring and recapitalization transactions with respect to the Issuer's capital structure (collectively, the "Transaction"), the Issuer entered into a Restructuring Support Agreement (the "Restructuring Support Agreement"), with BEP SS IV and Ascend. Pursuant to the terms of the Restructuring Support Agreement, the parties to the Restructuring Support Agreement agreed to implement the Transaction either as: (i) an out of court restructuring transaction (the "Out of Court Restructuring"); or (ii) to the extent that the terms of or the conditions precedent to the Out of Court Restructuring cannot be timely satisfied or waived, then as voluntary pre-packaged cases under chapter 11 of title 11 of the United States Code pursuant to a pre-packaged plan of reorganization. In connection with entry into the Restructuring Support Agreement, the Issuer, BEP SS IV and Ascend entered into (i) an exchange agreement (the "Exchange Agreement"), providing for the conversion of all of the Notes into Common Stock at the closing of the Out of Court Restructuring, (ii) the Fourth Amended and Restated Investor and Registration Rights Agreement (the "Fourth A&R IRRA"), providing customary registration rights and increasing the board designation right held by each of Ascend and BEP from one director to two directors at the closing of the Out of Court Restructuring and (iii) a Securities Subscription Agreement (the "Securities Subscription Agreement") with BEP SS IV, Ascend and the other parties thereto. Pursuant to the terms of the Securities Subscription Agreement, upon the closing of the Out of Court Restructuring, each of BEP SS IV and Ascent will purchase (A) $2,500,000 of shares of Common Stock and (B) up to $10 million of common stock purchase warrants. The Notes continue to be held for investment purposes, but the Reporting Persons may review and evaluate strategic alternatives, opportunities to increase shareholder value, Issuer operations, governance and control, and other matters related to the Issuer. Depending on market conditions and other factors (including consummation of the Out of Court Restructuring on the Issuer's businesses and prospects, availability of funds, alternative uses of funds and general economic conditions), the Reporting Persons may from time to time acquire additional or all securities of the Issuer or dispose of all or a portion of their investment in the Issuer.
