“(r) Agent. Each Buyer hereby (i) appoints AV Securities, Inc. (the “Required Holder”) as the agent hereunder (in such capacity, the “Agent”), and (ii) authorizes the Agent (and its officers, directors, employees and agents) to take such action on such ▇▇▇▇▇’s behalf in accordance with the terms hereof and thereof. The Agent shall not have, by reason hereof, a fiduciary relationship in respect of any Buyer. Neither the Agent nor any of its officers, directors, employees or agents shall have any liability to any Buyer for any action taken or omitted to be taken in connection hereof except to the extent caused by its own gross negligence or willful misconduct, and each Buyer agrees to defend, protect, indemnify and hold harmless the Agent and all of its officers, directors, employees and agents (collectively, the “Agent Indemnitees”) from and against any losses, damages, liabilities, obligations, penalties, actions, judgments, suits, fees, costs and expenses (including, without limitation, reasonable attorneys’ fees, costs and expenses) incurred by such Agent Indemnitee, whether direct, indirect or consequential, arising from or in connection with the performance by such Agent Indemnitee of the duties and obligations of Agent pursuant hereto. The Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Holder, and such instructions shall be binding upon all holders of Notes; provided, however, that the Agent shall not be required to take any action which, in the reasonable opinion of the Agent, exposes the Agent to liability or which is contrary to this Agreement, or any other Transaction Document or applicable law. The Agent shall be entitled to rely upon any written notices, statements, certificates, orders or other documents or any telephone message believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person, and with respect to all matters pertaining to this Agreement or any of the other Transaction Documents and its duties hereunder or thereunder, upon advice of counsel selected by it. As used in this Agreement, the term “Collateral Agent” shall mean any action undertaken in the past by the Agent prior to that certain Amendment No. 1 to Securities Purchase Agreement and Security Release, dated as of July 2, 2025, among the Company, the Buyers and the Agent, as the collateral agent and the Agent continues to be indemnified in full as pursuant to this clause for any action undertaken as such under the Transaction Documents and the Security Documents.”

“(z) Board of Directors. For so long as AV holds Notes issued to it hereunder, AV shall have the right to appoint one (1) director to the board of directors of the Company, at the next annual meeting of the Company’s stockholders; provided that, notwithstanding anything herein to the contrary, AV may not transfer the rights under this clause (z) to appoint any director to the board of directors of the Company to any Person, other than an Affiliate of AV.”

“(e) Entire Agreement; Amendments. Subject to the terms, conditions and restrictions of the Subordination Agreement (as defined below), this Agreement, the other Transaction Documents and the schedules and exhibits attached hereto and thereto and the instruments referenced herein and therein supersede all other prior oral or written agreements between the Buyers, the Company, its Subsidiaries, their affiliates and Persons acting on their behalf, including, without limitation, any transactions by any Buyer with respect to Common Stock or the Securities, and the other matters contained herein and therein, and this Agreement, the other Transaction Documents, the schedules and exhibits attached hereto and thereto and the instruments referenced herein

9

and therein contain the entire understanding of the parties solely with respect to the matters covered herein and therein; provided, however, nothing contained in this Agreement or any other Transaction Document shall (or shall be deemed to) (i) have any effect on any agreements any Buyer has entered into with, or any instruments any Buyer has received from, the Company or any of its Subsidiaries prior to the date hereof with respect to any prior investment made by such Buyer in the Company or (ii) waive, alter, modify or amend in any respect any obligations of the Company or any of its Subsidiaries, or any rights of or benefits to any Buyer or any other Person, in any agreement entered into prior to the date hereof between or among the Company and/or any of its Subsidiaries and any Buyer, or any instruments any Buyer received from the Company and/or any of its Subsidiaries prior to the date hereof, and all such agreements and instruments shall continue in full force and effect. Except as specifically set forth herein or therein, neither the Company nor any Buyer makes any representation, warranty, covenant or undertaking with respect to such matters. For clarification purposes, the Recitals are part of this Agreement. Subject to the terms, conditions and restrictions of the Subordination Agreement (as defined below), no provision of this Agreement may be amended other than by an instrument in writing signed by the Company and the Required Holder (as defined below), and any amendment to any provision of this Agreement made in conformity with the provisions of this Section 8(e) shall be binding on all Buyers and holders of Securities, as applicable; provided that no such amendment shall be effective to the extent that it (A) applies to less than all of the holders of the Securities then outstanding or (B) imposes any obligation or liability on any Buyer without such Buyer’s prior written consent (which may be granted or withheld in such ▇▇▇▇▇’s sole discretion); provided further that the provisions of Sections 4(r) and 4(s) above cannot be amended or waived without the additional prior written approval of the Agent or its successor. Subject to the terms, conditions and restrictions of the Subordination Agreement, no waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party, provided that the Required Holder may waive any provision of this Agreement, and any waiver of any provision of this Agreement made in conformity with the provisions of this Section 8(e) shall be binding on all Buyers and holders of Securities, as applicable, provided that no such waiver shall be effective to the extent that it (1) applies to less than all of the holders of the Securities then outstanding (unless a party gives a waiver as to itself only) or (2) imposes any obligation or liability on any Buyer without such Buyer’s prior written consent (which may be granted or withheld in such ▇▇▇▇▇’s sole discretion). No consideration (other than

10

reimbursement of legal fees) shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same consideration also is offered to all of the parties to the Transaction Documents, all holders of the Notes. From the date hereof and while any Notes are outstanding, the Company shall not be permitted to receive any consideration from a Buyer or a holder of Notes that is not otherwise contemplated by the Transaction Documents in order to, directly or indirectly, induce the Company or any Subsidiary (i) to treat such Buyer or holder of Notes in a manner that is more favorable than to other similarly situated Buyers or holders of Notes, or (ii) to treat any Buyer(s) or holder(s) of Notes in a manner that is less favorable than the Buyer or holder of Notes that is paying such consideration; provided, however, that the determination of whether a Buyer has been treated more or less favorably than another Buyer shall disregard any securities of the Company purchased or sold by any Buyer. The Company has not, directly or indirectly, made any agreements with any Buyers relating to the terms or conditions of the transactions contemplated by the Transaction Documents except as set forth in the Transaction Documents. Without limiting the foregoing, the Company confirms that, except as set forth in this Agreement, no Buyer has made any commitment or promise or has any other obligation to provide any financing to the Company, any Subsidiary or otherwise. As a material inducement for each Buyer to enter into this Agreement, the Company expressly acknowledges and agrees that (x) no due diligence or other investigation or inquiry conducted by a Buyer, any of its advisors or any of its representatives shall affect such Buyer’s right to rely on, or shall modify or qualify in any manner or be an exception to any of, the Company’s representations and warranties contained in this Agreement or any other Transaction Document and (y) unless a provision of this Agreement or any other Transaction Document is expressly preceded by the phrase “except as disclosed in the SEC Documents,” nothing contained in any of the SEC Documents shall affect such Buyer’s right to rely on, or shall modify or qualify in any manner or be an exception to any of, the Company’s representations and warranties contained in this Agreement or any other Transaction Document. “Required Holder” means AV.”

“(m) Remedies. Subject to the terms, conditions and restrictions of the Subordination Agreement, each Buyer and in the event of assignment by ▇▇▇▇▇ of its rights and obligations hereunder, each holder of Securities, shall have all rights and remedies set forth in the Transaction Documents and all rights and remedies which such holders have been granted at any time under any other agreement or contract and all of the rights which such holders have under any law. Subject to the terms, conditions and restrictions of the Subordination Agreement, any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. Furthermore, the Company recognizes that in the event that it or any Subsidiary fails to perform, observe, or discharge any or all of its or such Subsidiary’s (as the case may be) obligations under the Transaction Documents, any remedy at law would inadequate relief to the Buyers. Subject to the terms, conditions and restrictions of the Subordination Agreement, the Company therefore agrees that the Buyers shall be entitled to specific performance and/or temporary, preliminary and permanent injunctive or other equitable relief from any court of competent jurisdiction in any such case without the necessity of proving actual damages and without posting a bond or other security. The remedies provided in this Agreement and the other Transaction Documents shall be cumulative and in addition to all other remedies available under this Agreement and the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive relief). 

“(r) Subordination Agreement. This Agreement, the other Transaction Documents and the rights and obligations evidenced hereby and thereby are subordinate in the manner and to the extent set forth in the Subordination Agreement, dated as of July 2, 2025, by and among the Buyers and the Senior Agent (the “Subordination Agreement”). Each party hereto hereby irrevocably agrees to be bound by the provisions of the Subordination Agreement. In the event of any conflict between the terms of the Subordination Agreement and this Agreement or any other Transaction Document, the terms of the Subordination Agreement shall govern and control.”

12

“(s) Termination. This Agreement, each Note and each other Transaction Document (other than any Warrant) and all Obligations of the Company and its Subsidiaries under this Agreement, each Note and each other Transaction Document (other than any Warrant) shall terminate upon the payment in full of all obligations (including principal and interest, but excluding any contingent obligations for which no claim has been made) under the Notes.”
