This letter agreement (this “Agreement”) is entered into by and among Nuvve Holding Corp., a Delaware corporation (“Nuvve Parent”), Stonepeak Rocket Holdings LP, a Delaware limited partnership (“Stonepeak”), Evolve Transition Infrastructure LP, a Delaware limited partnership (“Evolve”), and Levo Mobility LLC, a Delaware limited liability company (the “Company” and together with Nuvve Parent, Stonepeak and Evolve, each a “Party” and collectively, the “Parties”), to set forth certain agreements with respect to the Company and its Business. Capitalized terms used but not defined herein shall have the meanings assigned to them in the Amended and Restated Limited Liability Company Agreement of the Company, dated as of the date hereof (the “LLCA”).
In consideration of the premises and the mutual covenants set forth herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties covenant and agree as follows:

Opportunities, including, for the avoidance of doubt, (i) acquiring, owning, selling, leasing, developing and managing electric buses, vehicles, transportation assets, and related charging infrastructure and ancillary assets that are provided to third parties that are not utilizing financing, leasing or other similar arrangements in respect of such assets (or provided to third parties that are utilizing financing, leasing or other similar arrangements with respect of such assets, so long as such investment or business opportunity does not include participating in or otherwise providing equity, debt or other financing to any entity or other person engaged in the businesses described in clause (a) of the definition of the “Business” as defined in the LLCA), (ii) Nuvve Parent providing services (including providing grid services and receiving revenues therefrom) to such third parties that are not utilizing financing, leasing or other similar arrangements in respect of such assets (or provided to third parties that are utilizing financing, leasing or other similar arrangements with respect of such assets, so long as such investment or business opportunity does not include Nuvve Parent or its Affiliates participating in or otherwise providing equity, debt or other financing to any entity or other person engaged in the businesses described in clause (a) of the definition of the “Business” as defined in the LLCA) (such investment or business opportunities described in clauses (i) and (ii), collectively, the “Exempted Business Opportunities”) or (iii) Nuvve Parent providing services to the Company pursuant to the DSA.
(b)Nuvve Parent shall, and shall cause each of its Affiliates to, use reasonable best efforts to source and structure each Business Opportunity so that it will constitute a Qualified Opportunity. Each such Business Opportunity will be presented to the Company and the Class B Representative in writing and with reasonable detail as to the nature, terms and other relevant factors relating to such Business Opportunity (including reasonable detail with respect to the satisfaction, as applicable, of each of the applicable qualifying criteria set forth on Exhibit A with respect to such Qualified Opportunity), and Nuvve Parent and each such Affiliate, as applicable, shall (i) provide any additional information and reasonable access to all relevant personnel and third party advisors, properties and books and records relating to such Business Opportunity to the extent reasonably requested by the Company or the Class B Representative and (ii) notify the Company and the Class B Representative as promptly as reasonably practicable of any changes to the nature, terms or other relevant factors relating to such Business Opportunity. The Board, acting with Special Approval, will determine in good faith whether such Business Opportunity constitutes a Qualified Opportunity and shall provide Nuvve Parent with written notice of its decision of whether such Business Opportunity was determined to be a Qualified Opportunity within ten (10) Business Days (which may be extended as mutually agreed by Nuvve Parent and the Board, acting with Special Approval) following receipt of any such written notice describing such Business Opportunity and all material information reasonably necessary for the Board to evaluate such Business Opportunity (including, for the avoidance of doubt, all information reasonably requested by the Board). Following such determination, the Board, acting with Special Approval, will consider such Business Opportunity and elect to either reject or pursue such Business Opportunity in its sole discretion. Within ten (10) Business Days (which may be extended as mutually agreed by Nuvve Parent and the Board, acting with Special Approval) following delivery of such notice to Nuvve Parent with respect to the determination of whether such Business Opportunity constitutes a Qualified Opportunity and the receipt of all material information reasonably necessary for the Board to evaluate such Business Opportunity (including, for the avoidance of doubt, all information reasonably requested by the Board), or twenty (20) Business Days (which may be extended as mutually agreed by Nuvve Parent and the Board, acting with Special Approval) if Stonepeak provides written notice to Nuvve Parent and the Company prior to the end of such

ten (10)-Business Day period (or such longer period as may have been mutually agreed by Nuvve Parent and the Board, acting with Special Approval) that a proposal for the Company to exercise its option with respect to the Business Opportunity has been submitted for consideration to the applicable investment committee or general partner, as applicable, of Stonepeak Infrastructure Partners and such investment committee or general partner is evaluating such Business Opportunity in good faith (such period, the “Consideration Period”), the Company shall provide Nuvve Parent with written notice of the Board’s decision (acting with Special Approval), in its sole discretion, to either reject or pursue such Business Opportunity and if such Business Opportunity was rejected, whether such rejection was primarily due to a failure to obtain Special Approval with respect to such Qualified Opportunity (if applicable). Any Business Opportunity that the Company so elects to pursue will hereinafter be referred to as an “Accepted Opportunity.” For purposes of this Agreement, “Qualified Opportunity” means a Business Opportunity that meets the qualifying criteria set forth on Exhibit A, as may be amended, supplemented or modified from time to time in accordance with Section 1(e).
(c)Nuvve Parent shall not, and shall cause its Affiliates not to, directly or indirectly (other than as a direct or indirect equityholder of the Company), individually or on behalf of any Person, company, enterprise, or entity, or as a sole proprietor, partner, equityholder, licensor, director, officer, principal, agent, employee or executive, or in any other capacity or relationship, pursue or participate in any manner (i)(A) in any Accepted Opportunity, or (B) from the date hereof until the earliest to occur of (1) the date that the aggregate Commitment Amount has been funded in full, (2) the end of the Commitment Period, and (3) a Monetization Event (such period in clause (B), the “Non-Compete Period”), in any Business Opportunity other than (x) a Rejected Opportunity to the extent permitted by the terms and conditions set forth in this Agreement or (y) a Business Opportunity with respect to the Business solely outside of North America that the Company elects not to participate in, (ii) during the Non-Compete Period, in any request for proposal or other similar process, in each case, with respect to any Exempted Business Opportunity until such request for proposal or other similar process has concluded and the applicable project has been finally awarded, or (iii) during the Non-Compete Period, in any Exempted Business Opportunity unless Nuvve Parent and its Affiliates have used good faith commercially reasonable efforts to provide the Company an opportunity to participate in such financing, leasing or other similar arrangements with respect to such investment or business opportunity as a financing source.
(d)If the Company elects not to participate in any Business Opportunity that was determined to be a Qualified Opportunity as determined by the Board in good faith with Special Approval, primarily due to a failure to obtain Special Approval (a “Rejected Opportunity”), then Nuvve Parent or its Affiliates may pursue such Rejected Opportunity for its or their own account without any further involvement of the Company, and in such event the Company shall not have any right or interest in such Rejected Opportunity nor any responsibility for any cost, expense or obligation associated with the further review, pursuit or acquisition by Nuvve Parent or its Affiliates of such Rejected Opportunity. In the event that (i) the material terms (including all terms relating to conditionality, pricing, costs, fees, revenues, quantity or any other economic provision regardless of materiality) of such Rejected Opportunity become, in the aggregate, more favorable to Nuvve Parent or its Affiliate, as applicable, from those contemplated when presented to the Company in writing, or (ii) Nuvve Parent or its Affiliates fails to enter into a definitive agreement relating to such Rejected Opportunity within one hundred and twenty days (120) days after the

​
​

earlier to occur of (A) the date that Nuvve Parent receives the Company’s written notice that it has elected not to pursue such Qualified Opportunity, and (B) the expiration of the applicable Consideration Period, in each case, the procedures set forth in this Section 1 shall once again apply, and Nuvve Parent and its Affiliates may not pursue such Rejected Opportunity without complying with such procedures in full.
(e)The qualifying criteria set forth on Exhibit A may only be waived or amended, supplemented or modified by Stonepeak in its reasonable sole discretion, unless such amendment, supplement or modification would reasonably be expected to be adverse to Nuvve Parent as determined by the Board in good faith with Special Approval, which shall also require Nuvve Parent’s prior written consent (not to be unreasonably withheld, conditioned or delayed). Nuvve Parent may propose, amendments, supplements or modifications to such qualifying criteria in good faith for Stonepeak’s review; provided, that Stonepeak shall have no obligation to consent to any such proposals.
Section 2Future Financing Transactions. If, during the six month period following the end of the Non-Compete Period, Nuvve Parent or any of its Affiliates, directly or indirectly, desires to enter into any material financing transaction, the primary use of proceeds from which will be used with respect to the Business or any business substantially similar to or competitive with the Business (a “Financing Transaction”), Nuvve Parent shall first give Stonepeak written notice (the “Stonepeak ROFO Notice”) of its desire to do so and provide Stonepeak with the proposed terms of the Financing Transaction. Within 15 days after receipt of the Stonepeak ROFO Notice (the “Stonepeak ROFO Response Period”), Stonepeak shall, on behalf of itself and its Affiliates, provide Nuvve Parent with written notice of its election to either (a) pursue the Financing Transaction, or (b) waive its rights in connection with the Financing Transaction (the “Stonepeak ROFO Response Notice”). If (x) Stonepeak waives its rights in connection with the Financing Transaction, (y) Stonepeak (or any of its Affiliates, as applicable) and Nuvve Parent (or any of its Affiliates, as applicable) fail to agree in good faith to a definitive agreement or binding term sheet relating to such Financing Transaction within 120 days (which may be extended as mutually agreed in writing by Nuvve Parent and Stonepeak) of Stonepeak delivering such notice to pursue the Financing Transaction; provided, that such parties have used commercially reasonable efforts to negotiate in good faith during such Period, or (z) Stonepeak fails to deliver a Stonepeak ROFO Response Notice by the end of the Stonepeak ROFO Response Period, then Nuvve Parent or its Affiliates may pursue and consummate such Financing Transaction with any other Person without any further obligation to Stonepeak except as set forth in this Section 2 (the circumstances described in clause (x), (y) or (z) of this subsection, a “Stonepeak Renounced Opportunity”). In the event that (i) the material terms (including all terms relating to conditionality, pricing, costs, fees or any other economic provision regardless of materiality) of such Stonepeak Renounced Opportunity become, in the aggregate, more favorable to Nuvve Parent or its Affiliates, as applicable, from those contemplated at the time the Stonepeak ROFO Notice was provided or (ii) Nuvve Parent or its Affiliates fails to enter into a definitive agreement or binding term sheet relating to such Stonepeak Renounced Opportunity within 120 days of the date such Financing Transaction was determined to be a Stonepeak Renounced Opportunity, the procedures set forth in this Section 2 shall once again apply, and Nuvve Parent and its Affiliates may not pursue such Financing Transaction without complying with such procedures in full. Notwithstanding the foregoing, Stonepeak may only exercise its rights pursuant to this Section 2 on behalf of an Affiliate that is not a Competitor.

Section 3Most Favored Nation. 
(a)From the date hereof until the date that is the fifth (5th) anniversary of the date that Nuvve or its Permitted Transferees no longer own any equity interests in the Company (such period, the “MFN Period”), Nuvve Parent hereby covenants and agrees, (i) that subject to the terms of this Section 3, none of the material terms (including all terms relating to conditionality, pricing, costs, fees, revenues, quantity or any other economic provision regardless of materiality) set forth in any Other Agreement is, has been, or will be more favorable to the Other Customer than those offered to the Company and its Affiliates with respect to any Proposed Contract, solely with respect to the MFN Covered Items, in each case, with respect to the applicable Asset Class, and (ii) to consider in good faith, on a case-by-case basis, the discount (including any additional discount) to be offered to the Company and its Subsidiaries with respect to the MFN Covered Items.
(b)Notwithstanding anything to the contrary herein, if during the MFN Period, Nuvve Parent is in breach of Section 3(a)(i), Nuvve Parent shall be deemed to have cured such breach if, and only if, Nuvve Parent (i) promptly provides written notice thereof to the Company prior to date that the Company or its Affiliates, as applicable, enters into the Proposed Contract or (ii) promptly (and in no event less than ten (10) Business Days following the discovery of such breach by Nuvve Parent), provides written notice thereof to the Company following the date that the Company or its Affiliates, as applicable, entered into the Proposed Contract; provided, that, in each case, so long as such notice includes a copy of the applicable Other Agreement (and any other relevant documents, agreements or material information with respect thereto), a revised Proposed Contract (such that the Company and its Affiliates would receive the benefit (including retroactively as of the date such Proposed Contract had been entered into, as applicable, with respect to clause (ii)) of the more favorable terms set forth in such Other Agreement) that Nuvve Parent or its Affiliates, as applicable, would enter into in good faith, and a good faith proposal with respect to proposed additional discounts, if any, for the Company and its Affiliates. Notwithstanding anything to the contrary herein, (w) this Section 3 shall only apply retroactively to any contract entered into between Company or its Affiliates, on one hand, and Nuvve Parent or its Affiliates, on the other hand, to the extent set forth in this Section 3(b); (x) the duration of the MFN Covered Items (including promotional pricing) shall be taken into account in the application of this Section 3(b); (y) solely with respect to the purchase price for charging infrastructure and related assets (including technology and intellectual property), (1) such purchase price included in such revised Proposed Contract shall, at minimum, unless otherwise waived by Nuvve Parent in its sole discretion, result in a gross margin to Nuvve Parent of at least ten percent (10%) as of the date of such revised Proposed Contract, and (2) the application of this Section 3(b) shall only apply to any Other Agreement that provides for a quantity of five (5) or more of the applicable Asset Class, and (z) in the event any individual Package Term is more favorable in any Other Agreement, the Company shall be required to irrevocably elect by written notice within ten (10) Business Days of receipt of Nuvve Parent’s notice either (1) for Nuvve Parent to incorporate such individual Package Term in such revised Proposed Contract it provides to the Company or its Affiliates along with the other applicable Package Terms set forth in such Other Agreement (which, for the avoidance of doubt, may be less favorable to the Company and its Affiliates) or (2) to waive its rights to adopt any of the Package Terms set forth in the Other Agreement in such revised Proposed Contract.

In the event of any dispute between Nuvve Parent and the Company with respect to this Section 3, either of Nuvve Parent or the Company may submit written notice of such dispute to such other Party. Upon delivery of such written dispute notice, such Parties shall cooperate and negotiate in good faith and use reasonable efforts to resolve such dispute. If such Parties are unable to resolve such dispute within 10 days after delivery of the written dispute notice, either Nuvve Parent or the Company may elect to, within three days following the end of such 10-day period, submit the dispute to binding arbitration in accordance with the Commercial Rules of the American Arbitration Association, by three arbitrators, of whom each such Party shall appoint one and the third shall be chosen by the other two arbitrators. The decision of a majority of the arbitrators shall be final and binding on such Parties and may be enforced before any court of competent jurisdiction and cannot be the subject of any appeal.

Unless otherwise agreed by such Parties, the arbitration proceeding shall commence as soon as practicable following such submission (and not later than three days following such submission), shall be completed as soon as reasonably practicable (and not continue for longer than 10 days from commencement) and the arbitrators shall issue their decision within five days after the conclusion of the proceeding. Each of the Company and Nuvve Parent shall bear its own costs relating to such arbitration; provided, that (x) if such arbitration results in a decision in favor of the Company, Nuvve Parent shall reimburse the Company for all of its reasonable and documented out-of-pocket expenses incurred with respect to such arbitration (including all costs of such arbitration), and (y) if such arbitration results in a decision in favor of Nuvve Parent, the Company shall reimburse Nuvve Parent for all of its reasonable and documented out-of-pocket expenses incurred with respect to such arbitration (including all costs of such arbitration).

Except as otherwise consented to by the disclosing Party in writing, each Party agrees that it will not, during or after the term of this Agreement, whether directly or indirectly through an Affiliate or otherwise, use any Confidential Information for any purposes other than in connection with its investment in the Company or Nuvve, as applicable, or disclose any Confidential Information for any reason or purpose whatsoever, except for disclosures: (a) to authorized directors, managers, officers, representatives, agents and employees of such Party or its Affiliates, the Company or its Subsidiaries and as otherwise may be proper in the course of performing such Party’s obligations, or enforcing such Party’s rights, under this Agreement, the LLCA and the agreements expressly contemplated hereby and thereby; provided, that each such Person is informed of the confidential nature of such Confidential Information, agrees to hold such Confidential Information confidential and that the disclosing Party remains liable for any breach of this provision by such Persons; (b) made by Stonepeak or Evolve to its limited partners, owners, co-investors, general partners and prospective investors; provided that if such limited partners, owners, co-investors, general partners and prospective investors are receiving Confidential Information (other than with respect to high-level summary information regarding the Company’s, or Nuvve Parent’s, as applicable, operations), such receiving Person shall be subject to confidentiality provisions at least as restrictive as the confidentiality obligations contained in this Agreement; (c) to any bona fide prospective purchaser of the equity or assets of the Company, Nuvee Parent, or its Affiliates or the Units or securities of Nuvve Parent held by such Party or its Affiliates, to prospective financing sources, or a prospective merger partner of such Party, Nuvve Parent, the Company or any of their respective Affiliates; provided, that such purchaser, financing sources, or merger partner agrees in writing to be bound by the provisions of this Section 8 or other confidentiality agreement that includes confidentiality and use provisions at least as restrictive as the provisions in this Agreement; (d) to attorneys, accountants and other professionals of such Party or its Affiliates who need to know such Confidential Information in order to perform services for such Party or Affiliate; (e) as is required to be disclosed by order of a court of competent jurisdiction, administrative body or governmental body, or by subpoena, summons or legal process, or by law, rule or regulation; and (f) as required to be disclosed in accordance with any securities law or other legal requirement.

Section 13Governing Law; Submission to Jurisdiction; Waiver of Jury Trial. This Agreement, and any action or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby, shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without giving effect to any choice-of-law principles that would require the application of the laws of any other jurisdiction. Each Party hereby irrevocably and unconditionally submits, for itself and its properties, to the exclusive jurisdiction of the courts of the State of New York sitting in New York City in the borough of Manhattan or, if it has or can acquire jurisdiction, in the United States District Court for the Southern District of New York located therein, as the appropriate, sole and exclusive venue to for purposes of any suit, action or other proceeding under or arising out of, or matter of interpretation of, this Agreement or the rights of the Parties under this Agreement. EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE MAXIMUM EXTENT IT MAY DO SO UNDER APPLICABLE LAW, ANY RIGHT TO A TRIAL BY JURY IN ANY SUIT, ACTION, OR OTHER PROCEEDING UNDER OR ARISING OUT OF, OR MATTER OF INTERPRETATION OF, THIS AGREEMENT OR THE RIGHTS OF THE PARTIES UNDER THIS AGREEMENT.

Section 14Assignment; Entire Agreement; Amendments; Waivers. No Party may assign any of its rights or obligations under this Agreement without the prior written consent of the other Party. Any attempted assignment in violation of this Agreement shall be void ab initio. This Agreement, the other Transaction Documents, that certain Non-Disclosure Agreement by and between Stonepeak and Nuvve Corporation, a Delaware corporation (the “NDA”), and that certain joinder to the NDA by and between Stonepeak and Evolve, constitute the entire agreement between the Parties with respect to the subject matter of this Agreement and supersede all prior understandings, whether written or oral, between Nuvve Parent, Stonepeak, Evolve, and the Company with respect to the contents hereof. This Agreement may not be amended or modified, in whole or in part, except by a written instrument executed by Stonepeak, Evolve, the Company and Nuvve Parent expressly so amending, or modifying this Agreement or any part hereof. Any agreement on the part of any Party to any waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. No failure or delay on the part of any Party in the exercise of any right hereunder shall impair such right or be construed as a waiver of, or acquiescence in, any breach of any agreement herein, nor shall any single or partial exercise of any such right preclude other or further exercise thereof or of any other right.
Section 15Specific Performance. Each Party agrees that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof and monetary damages, even if available, would not be an adequate remedy. It is accordingly agreed that each Party shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches (or threatened breaches) of this Agreement and to enforce specifically the performance of the terms and provisions hereof, without the necessity of proving irreparable harm or injury as a result of such breach or threatened breach and without the necessity to post any bond or other security in connection with any such order or injunction, this being in addition to any other remedy to which any Party is entitled to at law or in equity. 
Section 16Non-Recourse. Each Party agrees that this Agreement may only be enforced against, and any action for breach of this Agreement may only be made against, the Parties, and no claims of any nature whatsoever arising under or relating to this Agreement shall be asserted against any individual, entity or other person other than the Parties, and no individual, entity or other person that is not a Party shall have any liability arising out of or relating to this Agreement. 
Section 17Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each Party and its successors and permitted assigns and nothing in this Agreement, express or implied, is intended to or shall confer upon any other individual, entity or other person any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement; provided, that any individual, entity or other person other than the Parties shall be an express third-party beneficiary of Section 16.
Section 18Counterparts. This Agreement may be executed in any number of counterparts, each of which, when so executed, shall be deemed to be an original and all of which, taken together, shall constitute one and the same agreement. Delivery of an executed counterpart of this Agreement by e-mail or other electronic transmission (including “.pdf” or “.tif” format) shall be as effective as delivery of an original executed counterpart of this Agreement.

Section 19Severability; Enforcement. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any Party. Upon such a determination, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement be consummated as originally contemplated to the fullest extent possible. It is the intention of the Parties that if any of the restrictions or covenants contained in this Agreement is held to cover a geographic area or to be of a length of time that is not permitted by applicable law, or in any way construed to be too broad or to any extent invalid, such provision will not be construed to be null, void and of no effect; instead, the Parties agree that a court of competent jurisdiction will construe, interpret, reform or judicially modify this Agreement to provide for a covenant having the maximum enforceable geographic area, time period and other provisions (not greater than those contained herein) as will be valid and enforceable under such applicable law.
