Capitalized terms used herein and not otherwise defined herein shall have the meanings ascribed thereto in the Credit Agreements (as defined below), as applicable.

A. The Borrower, each Subsidiary of the Borrower from time to time party thereto (the “Guarantors”), and the Lender are parties to (i) that certain Credit Agreement (Cash Flow) dated as of December 15, 2025 (the “Existing Cash Flow Credit Agreement”, as amended by this Amendment and as may be further amended, modified, extended, restated, replaced, or supplemented from time to time, the “Cash Flow Credit Agreement”) and (ii) that certain Credit Agreement (Customer Orders) dated as of December 15, 2025 (the “Existing Customer Order Credit Agreement”, as amended by this Amendment and as may be further amended, modified, extended, restated, replaced, or supplemented from time to time, the “Customer Order Credit Agreement”; and together with the Cash Flow Credit Agreement, the “Credit Agreements”).

B. The Borrower has requested that Lender (i) amend the Existing Cash Flow Credit Agreement to increase the Commitment thereunder from $10,000,000 to $20,000,000 in accordance with Section 10.01 of the Cash Flow Credit Agreement and (ii) amend the Existing Customer Order Agreement to reduce the Commitment thereunder from $40,000,000 to $30,000,000 in accordance with Section 10.01 of the Customer Order Credit Agreement.

C. Lender is willing to agree to such requests, in accordance with and subject to the terms and conditions set forth herein, and the other parties hereto have agreed to join in the execution of this Amendment in their respective capacities, on the terms and subject to the conditions set forth herein.

sole discretion; provided, however, notwithstanding the foregoing or any other provision contained in this Agreement to the contrary, any reference contained in this Agreement to an “obligation” of Lender to make Loans hereunder shall be construed solely following the PIPE Closing Date to mean the discretionary authority of Lender to make Loans, if any, and not to a binding commitment on the part of Lender to Borrower to make Loans.

(c)“Commitment” means the obligation of Lender to make Loans to Borrower pursuant to Section 2.01, in an aggregate principal amount at any one time outstanding not to exceed $30,000,000 or such greater amount as Lender may agree in writing (including via e-mail) in its sole discretion.
