Notes payable, event of default description										Effective as of February 26, 2024 (the “Appointment Date”), the Company's Board of Directors (the "Board") appointed Mr. Eduardo Iniguez as a Class II director (the “Appointment”) for a term expiring at the annual meeting of stockholders to be held in respect of the Company’s fiscal year ending December 31, 2023. As a result of the Appointment, the total number of members of the Board from the Appointment Date through April 28, 2024, was six (the “Board Size”), including two directors in each class. Pursuant to the Third A&R Super Note and the Fourth A&R Super Note, the Board Size may have constituted an Event of Default under the Super Priority Note (the “Event of Default”). In connection with the Event of Default, the Company has taken the following remedial actions: (i) the Company requested to amend relevant sections of the Super Priority Note so as to provide for a total of six members of the Board, including two directors in each class; (ii) the Company has requested a waiver (effective as of the Appointment Date) by Mudrick of the Event of Default under the Super Priority Note resulting from the Board Size; and (iii) the Company has requested a waiver (effective as of the Appointment Date) by the Holders of a majority in aggregate principal amount of the Mudrick Convertible Notes currently outstanding of the cross default under the Indenture triggered by the Event of Default under the Super Priority Note. Effective as of April 29, 2024, with the issuance of the Fifth A&R Note, the Super Priority Note has been amended and restated to cure the Event of Default resulting from the Board Size. See Note 18 - Subsequent Events for additional information regarding the Fifth A&R Note. The Company continues to discuss the requested waivers with Mudrick.
