NOW, THEREFORE, in consideration of the mutual agreements and covenants contained therein and for other good and valuable consideration. the receipt and sufficiency of which hereby are acknowledged, Owner and Contractor agree as follows:

1. Term of Agreement

Unless extended by mutual written agreement of the Parties or terminated earlier in accordance with Section 5, the term of this Agreement shall commence on the Effective Date and continue with respect to each portion of the Products until the date on which (a) an EPC Agreement is entered into by the Parties which governs such portion of the Products, (b) with respect to any portion of the Products not governed by an EPC Agreement, Owner provides written notice to Contractor electing to take assignment of the underlying Product Subcontract applicable to such portion of the Products, and the rights thereunder (including warranties) and in such event, Contractor shall promptly effect such assignment to Owner (the “Term”), or (c) this Agreement is otherwise terminated for one of the reasons described in Section 5.1.

2. Process

2.1 From the Effective Date and for the Term, Contractor shall procure sufficient capacity and inventory from one or more manufacturers, vendors, or suppliers under one or more purchase orders, subcontracts, or other procurement agreements (each, a “Product Subcontract” and collectively, the “Product Subcontracts”) as required to deliver the Products set forth in Exhibit A,and Contractor shall make such Products available at the applicable Delivery Point identified in Exhibit Band Exhibit C in accordance with this Section 2.1and the ready-to-ship dates specified in Exhibit C(the “RTS Dates”). Contractor shall (i) provide Owner with written procurement updates or reports no less than twice per week that provide Owner with information reasonably available to Contractor that is sufficient to assess the procurement status of the Products, substantially in a form mutually agreed by the Parties and subject to any confidentiality restrictions applicable to Contractor’s manufacturers, vendors, and suppliers, (ii) provide Owner with written notice promptly after Contractor receives written confirmation from the applicable Product Subcontractor of a firm ready-to-ship dates for any portion of the Products, which date shall thereafter become the RTS Date for such portion of the Products for all purposes herein; and (iii) provide Owner with written notice of any event that Contractor has actual knowledge of and reasonably believes is likely to cause a material delay to an applicable RTS Date, within twenty-four (24) hours after Contractor obtains such knowledge. Such notice shall include the material facts then know to Contractor concerning the nature and anticipated duration of the event and the Products reasonably expected to be affected, and Contractor may supplement the notice as additional material information becomes reasonably available. Contractor shall issue all purchase orders for all Products within seven (7) Business Days after the Effective Date.

2.2 At any time following the Effective Date and prior to shipment of the Products by Contractor, Owner may, in its sole discretion, direct Contractor to deliver the Products to a different project site other than the one identified in Exhibit B. For the avoidance of doubt, Contractor shall not be permitted to ship or deliver any portion of the Products to any of Owner’s project sites prior to the execution of an EPC Agreement governing such portion of the Products.

3. Purchase Price

Owner shall pay to Contractor for the Products and for all obligations specified herein an amount equal to Three Hundred Forty Million Four Hundred Eighty-Seven Thousand Four Hundred Ninety-Nine and 00/100 Dollars ($340,487,499.00) (the “Purchase Price”).

4. Intent to Enter into EPC Agreement

4.1 The Parties intend to negotiate and execute one or more agreements covering engineering, procurement and construction (each an, “EPC Agreement”)for one or more Projects. An EPC Agreement shall include customary terms and conditions governing the manufacturing and delivery of the Products and the engineering, procurement and construction services provided by Contractor, including but not limited terms related to transit and delivery, insurance, indemnification, standards of performance, testing and commissioning, performance guarantees, liens, subcontractors, warranties, delay liquidated damages, performance liquidated damages, taxes and duties, audit, intellectual property, hazardous materials, safety, retainage, title and risk of loss, termination and events of default, completion dates, performance security and excused delays (including force majeure). This Agreement is preliminary in nature, except for the procurement of the Products, and is not intended to be, nor shall it be construed as, a contract for the development of any Project. No such contract shall exist, if at all, unless and until Contractor and Owner (or its affiliate) execute an EPC Agreement. In the event the Parties enter into an EPC Agreement, then, solely with respect to the portion of the Products governed by such EPC Agreement (“Transferred Equipment”): (a) this Agreement will be superseded and replaced by such EPC Agreement; (b) all obligations and responsibilities of the Parties under this Agreement will be governed by and deemed to have been performed under such EPC Agreement; and (c) all amounts incurred by or paid to Contractor pursuant to this Agreement shall be included in and credited to the contract sum established in such EPC Agreement and any amounts then remaining to be paid for such Transferred Equipment shall be paid, as and when required by such EPC Agreement. For the avoidance of doubt, with respect to any Products that are not Transferred Equipment and are not governed by an EPC Agreement, the payment obligations set forth in ExhibitDshall continue in full force and effect unless otherwise agreed by the Parties in writing. Notwithstanding the foregoing, neither Party is obligated to enter into an EPC Agreement unless and until it agrees to do so in its sole and absolute discretion.

5. Termination

(a)

by the mutual written agreement of the Parties;

(b)

by any Party, in the event the other Party engages in fraud, gross negligence, willful misconduct or intentional breach of this Agreement;

(c)

by any Party, upon the filing by or against the other Party of a petition or application for any proceeding relating to such Party as debtor under any bankruptcy or insolvency law of any jurisdiction;

(d)

automatically, upon (i) Contractor and Owner executing one or more EPC Agreements which cumulatively govern all portions of the Products, or (ii) with respect to any portion of the Products not governed by an EPC Agreement, Owner provides notice to Contractor pursuant to Section 1, notifying Contractor that Owner elects to take assignment of an underlying Product Subcontract applicable to such portion of the Products, and the rights thereunder (including warranties).

(e)

Upon assignment of any Product Subcontract and associated Products to Owner or any potential assignee under Section 11, except with respect to any and all obligations of Contractor under the applicable Product Subcontract in connection with events occurring prior to or as of the date of such assignment or any surviving obligations in connection with the Product Subcontract, Contractor shall have no further liability or obligation with respect to such assigned Products or Product Subcontract except to the extent arising from Contractor’s fraud, gross negligence, or willful misconduct occurring prior to such assignment.

(f)

Owner may terminate all or any portion of the Products for convenience upon not less than fourteen (14) days’ prior written notice to Contractor. After such termination, Owner shall owe Contractor the following costs (provided that there shall be no duplication of any costs owed by Owner): (i) all amounts then due to Contractor under this Agreement as of the date of termination; (ii) all cancelation costs incurred by Contractor in the close-out / termination of its Product Subcontracts, which may include non-cancellable costs, non-returnable costs, or otherwise committed costs to Product Subcontractors, including cancellation, restocking, transportation, storage, preservation, insurance, tax and financing costs directly resulting from such termination by Owner; and (iii) the reasonable internal costs, overhead and profit attributable to work performed by Contractor through the effective date of termination and any additional work required to be performed by Contractor as a result of such termination by Owner. Contractor shall submit all such costs for Owner’s review within sixty (60) days after the date of such termination by Owner. Contractor shall undertake commercially reasonable efforts to mitigate such costs, which shall include offsetting the net amounts actually received by Contractor, after deduction of reasonable and documented resale costs, from third parties in reselling the Products against amounts charged to Owner, but Contractor shall not be required to sell any Product for less than its commercially reasonable value or on terms that would cause Contractor to incur additional liability hereunder. Assignment or delivery of any terminated Products shall occur only after Contractor has received full payment of all applicable termination amounts and any required supplier consent. If Owner takes assignment of any Product Subcontracts, Owner shall not have any liability to Contractor for any cancelation or termination costs in connection with such subcontracts to the extent such costs are avoided as a result of the assignment. Amounts previously paid and properly allocable to the terminated portion of the Products shall be credited against the termination settlement. Contractor shall not be required to refund any previously paid amount except to the extent such amount exceeds the total termination settlement. Owner shall pay the termination settlement within thirty (30) days after receipt of Contractor’s invoice and reasonable supporting documentation demonstrating all costs in connection with such termination by Owner.

5.2 If the rights and obligations of Owner under this Agreement are assigned to a third party pursuant to Section 11after the execution of an EPC Agreement applicable to such rights and obligations for any reason at any time prior to the end of the term of such EPC Agreement, Owner shall pay Contractor a one-time termination fee equal to [***] (“Termination Fee”) pro-rated with respect to such portion of the Products being assigned. For the avoidance of doubt, in no event shall Contractor be entitled to the Termination Fee unless the Parties have executed an EPC Agreement applicable to such portion of Products to which the rights and obligations have been assigned in accordance with Section 4.

5.3 Notwithstanding anything else contained in this Agreement, if Owner elects to terminate this Agreement as a result of Contractor’s fraud, gross negligence, willful misconduct or intentional breach of this Agreement, Owner may elect that (i) all amounts paid to Contractor shall be immediately refunded to Owner and Owner shall be entitled to seek all remedies it has at law or (ii) Owner may take assignment of the underlying Product Subcontract. Upon termination of this Agreement, such termination shall not affect: (i) Owner’s obligation to pay any amount accrued or payable under this Agreement, including any termination settlement payable under Section 5.1(f); (ii) either Party’s rights, remedies, liabilities, or claims arising before the effective date of termination; (iii) any obligations concerning the assignment, transfer, storage, or delivery of Products or Product Subcontracts following termination; or (iv) any provision that expressly or by its nature is intended to survive termination, including Sections 6, 8, 10, and 15. Section 6 shall survive termination for the term of the NDA (as defined below).
