1. Scope of Relationship.

a. The Parties envision that (i) Altus Power’s primary role in the collaboration contemplated by this Agreement is to operate as a leading clean electrification company and (ii) CBRE’s primary role in the collaboration contemplated by this Agreement is to unlock customer demand for Altus Power through a robust referral program for potential customers.

The scope and/or terms of the Commercial Arrangements may be amended, supplemented or otherwise modified from time to time by the written agreement of the Parties (subject to Section 16.l), and such amended, supplemented or otherwise modified scope and/or terms of the Commercial Arrangements will constitute “Commercial Arrangements” hereunder and be subject to this Agreement.

2. Ancillary Agreements. To the extent the Parties deem it necessary or otherwise so desire, subject to Section 16.l, the Parties may enter into additional, more detailed agreements memorializing any aspect of the arrangements contemplated by this Agreement in greater specificity (each, an “Ancillary Agreement,” and, collectively, the “Ancillary Agreements”). The Parties agree and acknowledge that the Ancillary Agreements, any exhibits or attachments thereto, as well as any master services agreements, statements of work, purchase orders or any other contracts (oral or written) entered into on or after the date hereof will be subject to the terms and conditions of this Agreement and will not be deemed to amend or waive any provision of this Agreement, in each case except to the extent otherwise expressly agreed in writing by the Parties. For the avoidance of doubt, for all purposes of this Agreement, the Ancillary Agreements will not be construed to include the Business Combination Agreement or any of the other agreements executed in connection therewith.

3. Governance. To govern the Parties’ activities under this Agreement, as soon as practicable, but no later than thirty (30) days after the Effective Date (as defined below), the Parties shall create and operate an executive steering committee (the “Executive Steering Committee”) in accordance with this Section 3.

a. Executive Steering Committee.

i. The Executive Steering Committee will be responsible for providing strategic oversight in respect of the Commercial Arrangements, including: (i) establishing strategic objectives, priorities and goals for the Commercial Arrangements (including success metrics and key performance indicators (“KPIs”)); (ii) driving alignment and accountability for the Commercial Arrangements; (iii) reviewing financial and operational performance for the Commercial Arrangements (including evaluation of the performance of the Commercial Arrangements and results of the activities undertaken by the Parties herein as measured against the agreed-upon success metrics and KPIs), (iv) alignment on internal and external “go-to-market” strategy and development of integrated marketing

2

plans, including with respect to messaging on CBRE’s and Altus Power’s websites, any featured case studies or reports, attendance at any conferences and meetings and any presentation, speaking or display presence; (v) identification, discussion, development and implementation of any potential additional activities of interests, including any products, offerings or customer solutions the Parties wish to explore; (vi) establishing publicity, marketing and other public communication policies with respect to the Commercial Arrangements and other activities of the Parties under this Agreement or any Ancillary Agreement (including vis-à-vis clients, owners/investors and other third parties); (vii) establishing appropriate restrictions, procedures and guidelines for certain communications, discussions or other disclosures of information by and between the Parties and their respective Representatives (as defined below), as contemplated by Section 6; (viii) dispute resolution in accordance with the procedures set forth in Section 10 and such other actions expressly contemplated by the terms of this Agreement or any Ancillary Agreement; and (ix) such other matters as the Executive Steering Committee deems necessary or appropriate from time to time.

ii. The Executive Steering Committee will be comprised of four (4) individuals, or such other even number of individuals as the Parties may mutually determine from time to time, and CBRE and Altus Power will each be entitled to appoint one-half of the total number of such individuals on the Executive Steering Committee. Each Party may remove and replace any of its representatives on the Executive Steering Committee at any time and from time to time, upon written notice to the other Party. The identities and contact information for each Party’s initial representatives on the Executive Steering Committee are set forth on Exhibit A.

iii. The Executive Steering Committee will meet quarterly or as it otherwise deems necessary. Meetings of the Executive Steering Committee will be held on such dates and at such times and places (which may be by video or telephone conference) as may be determined by the Executive Steering Committee. Quorum for any meeting of the Executive Steering Committee will require the presence (in person or by proxy) of at least one representative on the Executive Steering Committee of each Party. All decisions of the Executive Steering Committee (whether in a meeting or by written consent) will require the affirmative vote of all of each Party’s representatives on the Executive Steering Committee. A representative of a Party on the Executive Steering Committee may designate another such representative of the same Party as a proxy for any meeting or written consent, including for quorum purposes.

iv. Each Party may invite non-voting observers to any meeting of the Executive Steering Committee, subject to appropriate confidentiality restrictions.

b. Notwithstanding anything to the contrary in this Agreement or any Ancillary Agreement and, for the avoidance of doubt, the Executive Steering Committee will not have any function or bearing on the governance of Altus Power, PubCo or CBRE or in any way that does not directly pertain to the Commercial Arrangements. The

3

Executive Steering Committee is designed to maximize the efficiency in executing, performing, guiding and evaluating the vision for the Commercial Arrangements. Neither the failure of the Executive Steering Committee to meet nor the failure of either such body to meet or satisfy any priority, objective, goal or other outcome of either of the Parties will be considered a breach or default by either Party or otherwise give rise to any liability or other obligation on behalf of either Party or any of their respective affiliates or representatives.

4. Commercial Arrangements and Commitments.

a. Subject to applicable legal, commercial, client-relationship and other considerations for any CBRE business unit, including any specific CBRE customer requirements and preferences, as soon as practicable after the date hereof, (i) CBRE will invite Altus Power to join CBRE’s strategic supplier program as a “Strategic Supplier” and execute and deliver to CBRE a strategic supplier program agreement substantially in the form attached hereto as Exhibit B (with such modifications as the Parties may agree), upon which CBRE will promote Altus Power as its preferred clean energy renewable provider/partner in accordance with the terms of such agreement, and (ii) CBRE and Altus Power will create a business opportunity referral program substantially on the terms set forth in Exhibit C (with such modifications as the Parties may agree).

b. The Parties will work together in good faith and reasonably cooperate to develop integrated marketing plans, including website, case studies, reports, conference/meeting, speaking/display presence.

c. CBRE will create and fund a “Renewable Energy Solutions” team to provide dedicated resources for the efficient interaction between CBRE and Altus Power to support the identification and prioritization of high quality referrals of opportunities, deploy a governance and reporting framework to drive performance and accountability of the Commercial Arrangements.

d. CBRE will reasonably collaborate with Altus Power to develop and bring to market new products and/or bundles for Altus Power’s customers.

e. Altus Power will consider in good faith inviting CBRE to become a solar tax equity partner for Altus Power, on a non-exclusive basis, on market terms to be mutually agreed. For the avoidance of doubt, CBRE shall not be obligated to provide any such financing (or other financing) to Altus Power unless CBRE expressly agrees in writing to do so nor shall Altus Power be obligated to approve CBRE as a financing partner, or otherwise enter into a financing arrangement with CBRE, unless Altus Power expressly agrees in writing.

f. CBRE will provide, at no cost to Altus Power, reasonable access to data-driven research and insights prepared by CBRE; provided, that CBRE will not be required to provide such access to the extent doing so will violate applicable laws or any contract

4

or obligation of confidentiality owed to a third party or result in the loss of attorney-client privilege.

g. Each of the Parties will evaluate opportunities to leverage technology and data to further the objectives of this Agreement.

h. The Parties expect that, to the extent either of them undertakes any of the actions contemplated in (a) through (g) above, the terms and conditions thereof will be governed by one or more Ancillary Agreements.

For the avoidance of doubt, CBRE acknowledges that it is not the exclusive provider to Altus Power of any of the commercial arrangements contemplated by this Agreement, and Altus Power is free to enter into similar or any other commercial arrangements with any other parties.

5. Term and Termination.

a. This Agreement will commence on the Closing Date (as defined in the Business Combination Agreement) (the “Effective Date”) and will continue for a period of seven (7) years from the Effective Date and thereafter shall automatically renew for successive one (1) year periods (unless either Party delivers a written notice of termination within ninety (90) days prior to the end of such seven-year period or, in the case of any one-year extension period, within ninety (90) days prior to the end of such one-year period, in which case this Agreement will expire at the end of such seven-year or one-year period, as the case may be) (the “Term”), unless terminated earlier pursuant to the terms of this Section 5.a. For the avoidance of doubt, any commercial collaboration activities by and between the Parties that occurred or occur prior to the Effective Date shall not be governed by and shall not in any way be deemed to be part of this Agreement.

b. This Agreement may be terminated:

i. Upon the mutual agreement in writing by the Parties.

ii. If the other Party materially breaches any provision of this Agreement and either the material breach cannot be cured or, if the material breach can be cured, if the non-breaching Party provides written notice (in reasonable detail) of such material breach to the breaching Party (which notice shall be deemed to commence the dispute resolution procedures under Section 10.a), and such material breach has not been cured or otherwise resolved (in each case, to the reasonable satisfaction of the non-breaching Party) by the later of (x) the end of the dispute resolution procedures under Section 10.a and Section 10.b and (y) the end of any other cure period mutually agreed in writing by the Parties or the Executive Steering Committee.

iii. If, at any time, any person or “group” (as such term is defined and used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), other than CBRE or any of its affiliates, acquires,

5

directly or indirectly, “beneficial ownership” (as such term is defined in Rule 13d-3 promulgated under the Exchange Act) of more than 30% of the outstanding equity securities or the consolidated assets of PubCo (by way of acquisition, merger, consolidation or otherwise), CBRE will have the right to terminate this Agreement within forty-five (45) days’ written notice to Altus Power to such effect.

iv. If, after the Closing (as defined in the Business Combination Agreement), CBRE (together with its affiliates) ceases to “beneficially own” (including rights to acquire by way of exchange, conversion, exercise of any security or otherwise) any equity securities of PubCo, either Party will have the right to terminate this Agreement on not less than ninety (90) days’ written notice to the other Party to such effect.

v. Without prejudice to any of its other rights and remedies hereunder or otherwise, either Party may terminate this Agreement, immediately upon written notice to the other Party to such effect, if the other Party: (a) has become insolvent; (b) has become unable, or admitted in writing its inability, to pay its debts as they mature; (c) has made a general assignment for the benefit of creditors or to an agent authorized to liquidate any substantial amount of its property; (d) has become the subject of “an order for relief” within the meaning of the United States Bankruptcy Code; (e) has become the subject of a creditor’s petition for liquidation, reorganization or to effect a plan or other arrangement with creditors; (f) has applied to a court for the appointment of a custodian or receiver for any of its assets and such receiver will not be discharged within sixty (60) days after his or her appointment; or (g) otherwise has become the subject of any insolvency proceeding that such Party does not promptly and actively oppose or is not dismissed within thirty (30) days after receiving notice of such proceeding.

vi. In the event of the termination of the Business Combination Agreement prior to the Closing (as defined in the Business Combination Agreement), this Agreement shall be deemed abandoned and for any reason shall automatically terminate and have no further force and effect.

c. Upon termination or expiration of this Agreement for any reason: (a) all activities under this Agreement and, except as otherwise expressly provided in such Ancillary Agreement, each Ancillary Agreement will terminate and (b) except as otherwise expressly provided in such Ancillary Agreements, each Party will, within thirty (30) days, return to the other Party its Confidential Information (as defined below), or will destroy all copies of the other Party’s Confidential Information in its possession and provide certification that such action has been taken. Notwithstanding the above, unless the Parties otherwise mutually agree in writing, each Party will fulfill all outstanding payment or performance obligations arising under this Agreement and, except as otherwise expressly provided in such Ancillary Agreement, each Ancillary Agreement in effect at the time of termination or expiration of this Agreement, and will agree on a process to wind-down activities required under this Agreement and such Ancillary Agreement.

7. Intellectual Property.

a. Neither Party will acquire any rights of ownership to any intellectual property worldwide held or licensed by the other Party, including any patents, patent applications (including any foreign, divisional, continuation or continuation-in-part applications based thereon), copyrights, inventions, improvements (whether patentable or not), trademarks, service marks, trade names, domain names, trade secrets, software, plans, methods, processes, designs, know-how, concepts, formulas, algorithms, research, studies, technologies, proprietary data, and any other intellectual property rights (collectively, “Intellectual Property”), by virtue of the Parties’ activities under this Agreement or any Ancillary Agreement.

Neither Party will acquire any rights of ownership to any Trademarks of the other Party under this Agreement or any Ancillary Agreement. On termination of this Agreement or upon the revocation by the licensing Party of any approved use, each Party will cease using any materials that bear the Trademarks of the other Party, except as required by applicable law.

a. In the event that there arises any dispute relating to this Agreement or any Ancillary Agreement that is not resolved in the normal course without commencing a dispute resolution process, within twenty (20) days of notice by one Party to the other to

10

commence the dispute resolution process with respect to such dispute, the Executive Steering Committee will meet to attempt to resolve such dispute in good faith. If the Executive Steering Committee does not come to a satisfactory resolution within sixty (60) days after such 20-day period (or such longer period as the Executive Steering Committee may agree), the Parties may proceed to the next step described in Section 10.b below.

b. Within ten (10) days of notice by one Party to the other to escalate the dispute resolution process with respect to a particular dispute, the chief executive officer of Altus Power and the global chief investment officer of CBRE (each, an “Executive Officer”) will meet to attempt to resolve such dispute in good faith. If the Executive Officers do not come to a satisfactory resolution within twenty (20) days after such 10-day period (or such longer period as the Executive Officers may agree in writing), the Parties may proceed to the next step described in Section 10.c below.

c. If a dispute remains unresolved after the expiration of the procedures described in Section 10.a and Section 10.b, then either Party may submit the unresolved dispute to binding arbitration in the State of Delaware (or other location as agreed to by the Parties) administered by the American Arbitration Association in accordance with its Commercial Arbitration Rules and, to the maximum extent applicable, pursuant to the Federal Arbitration Act, 9 U.S.C. 1 et seq. Either Party may commence the arbitration by giving notice to the other Party pursuant to Section 15 with a copy to the American Arbitration Association. Each Party agrees irrevocably to submit itself, in any suit to confirm the judgment or finding of such arbitrator, to the jurisdiction of the state or federal courts of the State of Delaware and waives any and all objections to jurisdiction that such Party may have under the laws of the State of Delaware or the United States.

d.

Should a Party fail to pay fees as required, the other Party may advance the same upon notice to such Party and will be entitled to a judgment from the arbitrator in the amount of such fees plus three percent (3%) per annum simple interest.

e. Notwithstanding the foregoing, the Parties agree that, without the necessity of commencing any dispute resolution procedure in accordance with this Section 10, a Party may commence proceedings in any court of competent jurisdiction to seek specific performance, an injunction or other equitable remedy in the event of any material breach by the other Party of any provision of this Agreement or any Ancillary Agreement.

EXHIBIT C

CBRE BROKER REFERRAL PROGRAM

Altus Power (“Altus”) and CBRE Broker Referral Program

Objective – Altus and CBRE will create an efficient referral program to encourage CBRE Brokers to refer attractive opportunities for Altus to market its products and services. Through CBRE’s broker community throughout the U.S., we expect that this program will lead to attractive opportunities for Altus due to CBRE’s market presence and CBRE broker / client relationships.

Communication Approach – Following the public announcement of the transaction, the parties will work together to prepare an education and marketing plan focused on prioritized markets (e.g., Tri-State, Washington DC/Baltimore, Los Angeles, Chicago) and will target select CBRE national teams (e.g., CBRE Land Services and CBRE’s National Partners). As the program expands, the team will prioritize additional markets and opportunistically discuss the opportunity with CBRE leaders and brokers.

Referral Process / Approach –

Qualified Referral – In order for a referral to be eligible for compensation it must meet certain minimum requirements as a “Qualified Referral.” A Qualified Referral will be determined by Altus, and requires, at a minimum, CBRE Broker to actively facilitate the initial communications between CBRE Renewables or Altus and the referral prospect (i.e. joint conference call, face-to-face meeting or referral contact information to allow direct communication). If such referral property or client is already an existing Altus client, then Altus can determine at its discretion if such referral is a Qualified Referral

Referral Fee – The Company will pay to CBRE a referral fee based on the following approach:

Illustrative examples: i) A 200k SF warehouse would imply a 2MW solar system and at $0.03/watt the referral fee could be $60k; ii) A 1.5M SF warehouse would imply a 15MW solar system and at $0.02/watt the referral fee could be $300k

The Referral Fee for New-Build Solar or Storage Systems will be paid out: i) 50% when client executes final agreement with Altus; and ii) 50% when Altus connects the solar or storage system to the grid for operation. The Referral Fees will be paid quarterly by Altus to CBRE and be accompanied by a detailed report providing additional information on the payments being made. CBRE will then pay individual CBRE Broker his/her referral fee.

The Referral Fee for Secondary Solar & Storage Systems will be paid out 100% on financial close of the purchase by Altus of the asset. The Referral Fees will be paid quarterly by Altus to CBRE and be accompanied by a detailed report providing additional information on the payments being made. CBRE will then pay individual CBRE Broker his/her referral fee.

Miscellaneous—Notwithstanding anything herein or otherwise to the contrary, Altus shall not be obligated to provide any products or services to any potential customer referred by a CBRE Broker, and all pricing decisions related to the Altus products and services shall be made by Altus. Any referral fee paid to CBRE will be applied to each individual’s brokerage commission structure and therefore CBRE’s Advisory business segment will receive a portion of the referral fee.
