(“Saulsbury”), as amended by the First Amendment to EPC Agreement dated March 6, 2026, the Second Amendment to EPC Agreement dated May 13, 2026, and the Third Amendment to EPC Agreement dated June 30, 2026 (collectively, the “EPC Agreement”).
B.    Saulsbury is party to an Equipment Supply Contract with Wärtsilä North America, Inc. (“Wärtsilä”) dated December 15, 2025, as amended by the First Amendment to the Equipment Supply Contract dated March 6, 2026, and the Second Amendment dated June 30, 2026 (collectively, the “EEQ Agreement”), which is incorporated by reference into the EPC Agreement as Attachment M, and under which Assignor is currently designated as “Owner” for purposes, among others, of the flow-down benefits, notices, warranties, remedies and step-in rights described in Section 4.6 of the EPC Agreement (collectively, the “EEQ Flow-Down Benefits”).
C.    Assignor and Assignee are parties to that certain Deposit and Exclusivity Agreement dated as of August 13, 2026 (the “Deposit Agreement”), pursuant to which Assignee paid to Assignor a first deposit of $3,000,000 (“Deposit One”) and a second deposit of $17,000,000 (“Deposit Two” and, together with Deposit One, the “Deposits”).

The Security Documents secure Assignor’s obligations under the Deposit Agreement pending closing and, as provided in Section 7.6 below, are to be released and terminated automatically upon closing.
E.    Assignor and Assignee are parties to a confidentiality agreement dated July 20, 2026, permitting EMPower to share the EPC Agreement and the EEQ Agreement with Net Power for purposes of evaluating the assignment contemplated herein (the “NDA”).

G.    Assignor desires to assign to Assignee, and Assignee desires to assume from Assignor, all of Assignor’s right, title, obligations and interest in, to, and under the EPC Agreement, together with the EEQ Flow-Down Benefits, on the terms set forth herein, so that Assignee may utilize the engineering, procurement, and construction scope and the associated equipment procurement position for a separate power generation project at Assignee’s anticipated site.

2.5    Conditions to Effectiveness. The assignment and assumption set forth in this Article 2 shall become effective only upon satisfaction (or written waiver by the Party entitled to the benefit thereof), concurrently with the Assignment Effective Date, of each of the following conditions: (a) Assignor’s confirmed receipt of the Reimbursement Amount and the Premium (net of the Deposit Credit) in immediately available funds in accordance with Section 3.2; (b) the due execution and delivery of the Consent and Acknowledgment, in the form attached as Exhibit A, by Saulsbury and Wärtsilä; (c) the Consent and Acknowledgment including the written confirmations of each of Saulsbury and Wärtsilä described in clauses (a) through (d) of Section 5.1 of the Deposit Agreement; (d) Assignor’s delivery of the schedule, supporting invoices and proof of payment substantiating the Reimbursement Amount; and (e) the representations and warranties of Assignor in Article 5 being true and correct as of the Assignment Effective Date.

Page 3 of 14


3.1    Purchase Price. As consideration for the Assigned Interests, Assignee shall: (a) pay to Assignor the Reimbursement Amount; (b) pay to Assignor the Premium, less a credit in the amount of $20,000,000 (the “Deposit Credit”) representing the Deposits retained by Assignor pursuant to Section 2.3 of the Deposit Agreement; and (c) assume the Assumed Liabilities as provided in Section 2.2 (collectively, the “Purchase Price”).

3.2    Payment Mechanics. Assignee, as of the Assignment Effective Date, has paid the Reimbursement Amount and the Premium (net of the Deposit Credit) to Assignor by wire transfer of immediately available funds to the following account of Assignor:
Beneficiary Name: EMPower USA, LLC Beneficiary Address: 4900 Woodway Dr. Suite 1200, Houston, TX 77056 Bank Name: JPMorgan Chase Bank, N.A.
ABA Routing Number: [***] Account Number: [***]
3.3    Full Notice to Proceed Payment. The Parties acknowledge that the Full Notice to Proceed Payment is due and payable under the EPC Agreement (as amended) on August 31, 2026, and that as of the Assignment Effective Date, any extension of such deadline may be requested by Assignee to Saulsbury and Wärtsilä in connection with the Transaction. Accordingly:
(a)    Since the Full Notice to Proceed Payment has not been paid as of the Assignment Effective Date, it shall constitute an Assumed Liability, and Assignee shall pay the Full Notice to Proceed Payment directly to Saulsbury (or as otherwise directed under the EPC Agreement) on or before August 31, 2026 (or such other date as set forth in the fully executed Consent and Acknowledgment or in any other writing executed by Assignee and Saulsbury).
3.4    No Set-Off. Except as expressly provided in Section 3.1 regarding the Deposit Credit and as contemplated by Section 3.3 of the Deposit Agreement, Assignee shall not have any right to set off, deduct, or withhold any portion of the Purchase Price on account of any actual or asserted claim against Assignor; provided that any amount to be deducted, set off, or withheld by Assignee pursuant to Section 3.3 of the Deposit Agreement shall be subject to prior written notice to Assignor reasonably describing the basis and amount thereof. If Assignor disputes any such deduction, set-off or withholding by notice given within three (3) business days of its receipt of Assignee’s notice, Assignee shall retain the disputed amount rather than apply it, and shall release the retained amount to Assignor promptly upon resolution of the dispute by written agreement of the Parties or by final determination. Any amount retained pursuant to this Section 3.4 shall be held in a segregated account of Assignee and released in accordance with the resolution of the dispute within five (5) business days thereof. If the Parties have not resolved the dispute within ninety (90) days after Assignor’s objection, the retained amount shall be released to Assignor unless Assignee has by then delivered a claim notice under Section 8.1 in respect of the disputed amount. Release of any retained amount to Assignor is without prejudice to Assignor’s obligation under Section 3.3 of the Deposit Agreement to discharge the underlying liability.
ARTICLE 4
ASSUMED LIABILITIES; EXCLUDED LIABILITIES

Page 7 of 14


responsibility, cost or risk associated with obtaining or implementing any such consent, approval, amendment, change order or modification.

7.6    Security Release. Assignee shall deliver, pursuant to Section 7.2 of the Security Agreement, UCC-3 termination statements (or equivalent releases) with respect to any financing statement filed under the Security Agreement, it being acknowledged that the security interest created thereby automatically terminates upon closing since the Assigned Interests are, concurrently therewith, transferred to Assignee outright pursuant to this Agreement.
