Form of Performance Restricted Stock Unit Award Grant Notice and Award Agreement

As a key leader in our business, you are in a position to have significant influence on the performance and success of OPAL Fuels Inc. (the “Company”). I am pleased to inform you that, in recognition of the role you play in our collective success, you have been granted a Performance Restricted Stock Unit Award. This award is subject to the terms and conditions of the OPAL Fuels Inc. 2022 Omnibus Equity Incentive Plan, this Grant Notice, and the following Performance Restricted Stock Unit Agreement. The details of this award are indicated below.

THIS PERFORMANCE RESTRICTED STOCK UNIT AWARD AGREEMENT (together with the above grant notice (the “Grant Notice”), this “Agreement”) is made and entered into as of the date set forth on the Grant Notice by and between the Company and the individual (the “Grantee”) set forth on the Grant Notice.

WHEREAS, pursuant to the OPAL Fuels Inc. 2022 Omnibus Equity Incentive Plan (the “Plan”), the Administrator (the “Administrator”) has determined that it is to the advantage and best interest of the Company to grant to the Grantee this award of performance-based Restricted Stock Units (the “PRSUs”) as set forth in the Grant Notice and subject to the terms and provisions of the Plan, which is incorporated herein by reference, and this Agreement (the “Award”).

NOW, THEREFORE, in consideration of the mutual agreements contained herein, the Grantee and the Company hereby agree as follows:

1.Acceptance of Agreement. Grantee has reviewed all of the provisions of the Plan, the Grant Notice and this Performance Restricted Stock Unit Award Agreement. By accepting this Award, Grantee agrees that this Award is granted under and governed by the terms and conditions of the Plan, the Grant Notice and this Performance Restricted Stock Unit Award Agreement, and the applicable provisions contained in a written employment agreement (if any) between the Company or an Affiliate and the Grantee. Grantee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator on questions relating to the Plan, the Grant Notice, this Agreement and, solely in so far as they relate to this Award, the applicable provisions contained in a written employment agreement (if any) between the Company or an Affiliate and the Grantee. If Grantee signs this Agreement and Grant Notice electronically, Grantee’s electronic signature of this Agreement shall have the same validity and effect as a signature affixed by hand.

2.Grant of Award. The PRSUs granted hereunder pursuant to Section 9 of the Plan shall be subject to the terms and provisions of the Plan, and all capitalized terms not otherwise defined herein shall have the meaning ascribed to them in the Plan. For purposes of this Agreement, “Termination” shall mean the termination of the employment or provision of services of the Grantee with the Company and all Affiliates thereof (including because of the Grantee’s employer ceasing to be an Affiliate of the Company); and “Termination Date” shall mean the date of the Termination. For purposes of this Agreement, Termination will not occur when Grantee goes on a military leave, a sick leave or another bona fide leave of absence that was approved by the Company in writing if the terms of the leave provide for continued service crediting, or when continued service crediting is required by Applicable Laws. Notwithstanding the foregoing, an approved leave of absence for six months or less, which does not in fact exceed six months, will not result in Termination for purposes of this Agreement. However, Termination will occur when approved leave described in this Section 2 ends, unless Grantee immediately returns to active work. Grantee shall be entitled to receive dividends declared during the Restricted Period with respect to the number of Shares covered by PRSUs, which dividends will be paid to Grantee at the time (and to the extent) Shares in respect of the related PRSUs are delivered to the Grantee under the terms of this Agreement.

3.Vesting.

4.Transfer and Settlement of PRSUs. The PRSUs issued under this Agreement may not be sold, transferred or otherwise disposed of and may not be pledged or otherwise hypothecated (each, a “Transfer”). In addition, Grantee shall not sell any Shares received with respect to PRSUs (even following settlement of PRSUs) at a time when Applicable Laws, regulations or Company’s or underwriter trading policies prohibit such sale. The applicable portion of this Award (to the extent vested) shall be settled by the Company by the issuance and delivery of Shares as soon as reasonably practical after (but no later than 60 days after) the Delivery Dates, as indicated in the Grant Notice, to the Grantee (or if applicable, the beneficiaries of the Grantee). Any issuance of Shares shall be made only in whole Shares, and any fractional shares shall be distributed in an equivalent cash amount.

5.General.

1.1Governing Law. This Agreement shall be governed by and construed under the laws of the State of Delaware.

1.2Community Property. Without prejudice to the actual rights of the spouses as between each other, for all purposes of this Agreement, the Grantee shall be treated as agent and attorney-in-fact for that interest held or claimed by his or her spouse with respect to this Award and the parties hereto shall act in all matters as if the Grantee was the sole owner of this Award. This appointment is coupled with an interest and is irrevocable.

1.3No Employment Rights. Nothing contained herein shall be construed as an agreement by the Company or any of its subsidiaries, express or implied, to employ the Grantee or contract for the Grantee’s services, to restrict the Company’s or such subsidiary’s right to discharge the Grantee or cease contracting for the Grantee’s services or to modify, extend or otherwise affect in any manner whatsoever the terms of any employment agreement or contract for services which may exist between the Grantee and the Company or any Affiliate.

1.4Application to Other Stock. In the event any capital stock of the Company or any other corporation shall be distributed on, with respect to or in exchange for Shares underlying PRSUs as a stock dividend, stock split, reclassification, recapitalization or similar transaction in connection with any merger or reorganization or otherwise, all restrictions, rights and obligations set forth in this Agreement shall apply with respect to such other capital stock to the same extent as they are, or would have been applicable, to the Shares underlying PRSUs on or with respect to which such other capital stock was distributed, and references to “Company” in respect of such distributed stock shall be deemed to refer to the company to which such distributed stock relates.

1.5No Third-Party Benefits. Except as otherwise expressly provided in this Agreement, none of the provisions of this Agreement shall be for the benefit of, or enforceable by, any third-party beneficiary.

1.6Successors and Assigns. Except as provided herein to the contrary, this Agreement shall be binding upon and inure to the benefit of the parties, their respective successors and permitted assigns.

1.7No Assignment. Except as otherwise provided in this Agreement, the Grantee may not assign any of his or her rights under this Agreement without the prior written consent of the Company, which consent may be withheld in its sole discretion. The Company shall be permitted to assign its rights or obligations under this Agreement so long as such assignee agrees to perform all of the Company’s obligations hereunder.

1.8Severability. The validity, legality or enforceability of the remainder of this Agreement shall not be affected even if one or more of the provisions of this Agreement shall be held to be invalid, illegal or unenforceable in any respect.

1.9Equitable Relief. The Grantee acknowledges that, in the event of a threatened or actual breach of any of the provisions of this Agreement, damages alone will be an inadequate remedy, and such breach will cause the Company great, immediate and irreparable injury and damage. Accordingly, the Grantee agrees that the Company shall be entitled to injunctive and other equitable relief, and that such relief shall be in addition to, and not in lieu of, any remedies it may have at law or under this Agreement.

1.10Jurisdiction. Any suit, action or proceeding with respect to this Agreement, or any judgment entered by any court in respect of any thereof, shall be brought in any court of competent jurisdiction in the State of Delaware, and the Company and the Grantee hereby submit to the exclusive jurisdiction of such courts for the purpose of any such suit, action, proceeding or judgment. The Grantee and the Company hereby irrevocably waive (i) any objections which it may now or hereafter have to the laying of the venue of any suit, action or proceeding arising out of or relating to this Agreement brought in any court of competent jurisdiction in the State of Delaware and (ii) any claim that any such suit, action or proceeding brought in any such court has been brought in any inconvenient forum.

1.11Taxes. By agreeing to this Agreement, the Grantee represents that he or she has reviewed with his or her own tax advisors the federal, state, local and foreign tax consequences of the transactions contemplated by this Agreement and that he or she is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. The Company shall be entitled to require a cash payment by or on behalf of the Grantee and/or to deduct from the Shares or cash issuable hereunder or from other compensation payable to the Grantee the minimum amount of any sums required by federal, state or local tax law to be withheld (or other such sums that that will not cause adverse accounting consequences for the Company and is permitted under applicable withholding rules promulgated by the Internal Revenue Service or another applicable governmental entity) with respect to the Performance Restricted Stock Unit Award.

1.12Section 409A Compliance. The intent of the parties is that payments and benefits under this Agreement comply with Section 409A of Code to the extent subject thereto, and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted and be administered to be in compliance therewith. Notwithstanding anything contained herein to the contrary, to the extent required to avoid accelerated taxation and/or tax penalties under Section 409A of the Code, the Grantee shall not be considered to have separated from service with the Company for purposes of this Agreement and no payment shall be due to the Grantee under this Agreement on account of a separation from service until the Grantee would be considered to have incurred a “separation from service” from the Company within the meaning of Section 409A of the Code. Any payments described in this Agreement that are due within the “short-term deferral period” as defined in Section 409A of the Code shall not be treated as deferred

compensation unless applicable law requires otherwise. Notwithstanding anything to the contrary in this Agreement, to the extent that any amounts are payable upon a separation from service and such payment would result in accelerated taxation and/or tax penalties under Section 409A of the Code, such payment, under this Agreement or any other agreement of the Company, shall be made on the first business day after the date that is six (6) months following such separation from service (or death, if earlier). The Company makes no representation that any or all of the payments described in this Agreement will be exempt from or comply with Section 409A of the Code and makes no undertaking to preclude Section 409A of the Code from applying to any such payment. If it is determined that the terms of this Agreement have been structured in a manner that would result in adverse tax treatment under Section 409A of the Code, the parties agree to cooperate in taking all reasonable measures to restructure the arrangement to minimize or avoid such adverse tax treatment without materially impairing Grantee’s economic rights. The Grantee shall be solely responsible for the payment of any taxes and penalties incurred under Section 409A.

1.22Amendments and Termination. To the extent permitted by the Plan, this Agreement may be wholly or partially amended, altered or terminated at any time or from time to time by the Administrator or the Board, but no amendment, alteration or termination shall be made that would materially impair the rights of a Grantee under this Performance Restricted Stock Unit Award Agreement without such Grantee’s consent.

1.23Clawback of Incentive Compensation. If the Company is required to prepare an accounting restatement of its financial statements due to the Company’s material noncompliance (whether one occurrence or a series of occurrences of noncompliance) with any financial reporting requirement under the securities laws (including if the Company is required to prepare an accounting restatement to correct an error (or a series of errors)) (a “Covered Accounting Restatement”), and if such Covered Accounting Restatement includes (i) restatements that correct errors that are material to previously issued financial statements (commonly referred to as “Big R” restatements), or (ii) restatements that correct errors that are not material to previously issued financial statements, but would result in a material misstatement if (a) the errors were left uncorrected in the current report or (b) the error correction was recognized in the current period (commonly referred to as “little r” restatements), then the Committee may require Grantee to repay (in which event, Grantee shall, within thirty (30) days of the notice by the Company, repay to the Company) or forfeit (in which case, Grantee shall immediately forfeit to the Company) to the Company, and Grantee hereby agrees to so repay or forfeit, that portion of the Incentive Compensation (as defined below) received by Grantee during the period comprised of the Company’s three (3) completed fiscal years (together with any intermittent stub fiscal year period(s) of less than nine (9) months resulting from Company’s transition to different fiscal year measurement dates) immediately preceding the date the Company is deemed (as described below) to be required to prepare a Covered Accounting Restatement (such period, the “Look-Back Period”), that the Committee determines was in excess of the amount of Incentive Compensation that Grantee would have received during such Look-Back Period, had such Incentive Compensation been calculated based on the restated amounts, and irrespective of any fault, misconduct or responsibility of Grantee for the Covered Accounting Restatement. It is specifically understood that, to the extent that the impact of the

Covered Accounting Restatement on the amount of Incentive Compensation received cannot be calculated directly from the information therein (e.g., if such restatement’s impact on the Company’s stock price is not clear), such excess amount of Incentive Compensation shall be determined based on a reasonable estimate by the Committee of the effect of the Covered Accounting Restatement on the applicable financial measure (including the stock price or total shareholder return) based upon which the Incentive Compensation was received. The amount of the Incentive Compensation to be recouped shall be determined by the Committee in its sole and absolute discretion and calculated on a pre-tax basis, and the form of such recoupment of Incentive Compensation may be made, in the Committee’s sole and absolute discretion, through the forfeiture or cancellation of vested or unvested Awards, cash repayment or both. Incentive Compensation shall be deemed received, either wholly or in part, in the fiscal year during which the financial reporting measure specified in such Incentive Compensation award is attained (or with respect to, or based upon the achievement of, such financial reporting measure, such Incentive Compensation was granted, earned or vested, as applicable), even if the payment, vesting or grant of such Incentive Compensation occurs after the end of such fiscal year. For purposes of this Section 5.23, the Company is deemed to be required to prepare a Covered Accounting Restatement on the earlier of: (A) the date upon which the Board or an applicable committee thereof, or the officer or officers of the Company authorized to take such action if Board action is not required, concludes, or reasonably should have concluded, that the Company is required to prepare a Covered Accounting Restatement; or (B) the date a court, regulator, or other legally authorized body directs the Company to prepare a Covered Accounting Restatement. For the purposes of this Agreement, “Incentive Compensation” shall mean any compensation (including any Award or any other short-term or long-term cash or equity incentive award or any other payment) that is granted, earned, or vested based wholly or in part upon the attainment of any financial reporting measure (i.e., any measures that are determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any measure that is derived wholly or in part from such measures, including stock price and total shareholder return). For the avoidance of doubt, financial reporting measures include “non-GAAP financial measures” for purposes of Exchange Act Regulation G and 17 CFR 229.10, as well as other measures, metrics and ratios that are not non-GAAP measures, like same store sales. Financial reporting measures may or may not be included in a filing with the Securities and Exchange Commission, and may be presented outside the Company’s financial statements, such as in Management’s Discussion and Analysis of Financial Conditions and Results of Operations or the performance graph.
