certain Business Combination Agreement, dated as of the date hereof (as may be amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Business Combination Agreement”), pursuant to which
and subject to the terms and conditions of which, among other things, indirect shareholders of Altus Power will exchange certain equity interests for shares of PubCo and own a majority of the shares of PubCo at the closing of the Business

WHEREAS, the respective boards of directors of each of the Parties, as well as the board of directors of PubCo (acting upon
the unanimous recommendation of the CBAH Special Committee (as defined in the Business Combination Agreement)), have unanimously approved this Agreement. 

NOW, THEREFORE, the Parties agree as follows: 

 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. 
 b. The specific commercial arrangements of the Parties pursuant to this Agreement are
the provision by each Party to the other Party of certain services and related commitments in accordance with Section 4 (the “Commercial Arrangements”). 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. 

  
 6 

 d. The Parties agree that the terms of this
Section 5 (Term and Termination) and of Section 6 (Confidentiality), Section 7 (Intellectual Property), Section 10 (Dispute Resolution),
Section 11 (Warranties and Limitations), Section 12 (Indemnification), Section 13 (Limitations of Liability) and Section 16 (Miscellaneous
Provisions) will survive the termination or expiration of this Agreement. 
 6. Confidentiality. 

a. Each Party acknowledges and agrees that this Agreement and any Ancillary Agreement and the transactions and
other activities contemplated hereby and thereby are or may constitute confidential and proprietary information of either or both Parties. From and after the date hereof until the fifth (5th) anniversary of the earlier of the termination or
expiration of this Agreement, each of the Parties shall, and shall cause their respective affiliates and representatives to, treat as strictly confidential and not disclose or use for any purpose (other than the purposes contemplated by this
Agreement and the Ancillary Agreements) any information received or obtained in connection with this Agreement and any Ancillary Agreement and the transactions and other activities contemplated hereby and thereby, or performing their respective
obligations under, this Agreement or any Ancillary Agreement which relates to, including, without limitation, (i) the provisions of this Agreement and any Ancillary Agreement, (ii) the negotiations relating to this Agreement and any
Ancillary Agreement, (iii) any information relating to the business, customers, financial or other affairs (including future plans and targets) of each Party and its affiliates, in each case for the foregoing, other than information that

legal or fiduciary obligation owed to such Party) or (z) is independently developed by the applicable Party without the use of any information provided to such Party in connection with this Agreement or the transactions contemplated hereby.

 b. The provisions of this Section 6 shall not prohibit disclosure or use of any
information by a Party if and to the extent: (i) the disclosure or use is required by applicable law, any governmental authority or any recognized stock exchange on which the shares of such Party or its affiliates are listed (including where
this is required as part of any actual or potential offering, placing and/or sale of securities of such person), provided that, prior to disclosure or use of any information pursuant to this clause (i), such Party, as the case may be, shall
promptly notify the other Party of such requirement with a view to providing it with the opportunity to contest such disclosure or use or otherwise to agree the timing and content of such disclosure or use, except that no notice, consent or approval
shall be required to be provided for disclosure (x) pursuant to a routine request by a governmental authority not specifically targeting such information or (y) to the extent that such notice

  
 7 

 
would not be practicable under the circumstances or is prohibited by applicable law, (ii) the disclosure or use is required for the purpose of any lawsuit or other proceeding arising out of
this Agreement or any Ancillary Agreement, (iii) the disclosure is made to a governmental authority in connection with taxes or the tax affairs of such Party, or (iv) the disclosure is made to any parent holding company of such Party or
subsidiary of such Party or parent holding company or any director, officer, employee, or legal, tax or financial advisor of such Party or of any such parent holding company or subsidiary (collectively, “Representatives”) on a
confidential basis, provided that each such Representative is informed of, and agrees to comply with, the provisions of this Section 6 (it being understood that such Party shall be responsible for any breaches of
this Section 6 by each such Representative as if such Representative were a party hereto). 

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. 
 b. All Intellectual Property, including modifications and improvements, associated
with the CBRE products and services provided under this Agreement or any Ancillary Agreement will be the sole property of CBRE (the “CBRE Intellectual Property”). CBRE will retain all right, title and interest to the CBRE
Intellectual Property and to any modifications and improvements made by either Party to the CBRE Intellectual Property, and to the extent Altus Power retains any right, title or interest in the CBRE Intellectual Property, Altus Power hereby assigns
and agrees to assign such right, title or interest in the CBRE Intellectual Property to CBRE. 
 c. All

d. Subject to the other provisions of this Agreement, any Intellectual Property jointly developed by the
Parties under this Agreement or any Ancillary Agreement pursuant to a written agreement agreeing to joint ownership will be jointly owned; provided, 

  
 8 

 
that the Parties will only develop joint Intellectual Property in accordance with an Ancillary Agreement. 

e. Each Party hereby grants to the other Party a non-exclusive, non-transferable (except as permitted in Section 16.c), non-sublicensable (except to affiliates and its and their service providers as necessary to perform hereunder), royalty-free license
to use its Intellectual Property (other than trademarks, service marks, logos, branding, and other indicia of origin) solely during the Term and solely to the extent necessary for the performance of this Agreement and any Ancillary Agreement, if
applicable; provided, however, that the rights granted under this Section 7.e do not include any Intellectual Property (whether owned or licensed) for which either Party has no right to grant a license to the
other Party or that would otherwise cause such Party to violate the terms of an agreement with any third party. For the avoidance of doubt, neither Party shall have any right to use or practice the other Party’s Intellectual Property after the
Term or for any reason other than as expressly provided in this Agreement or any Ancillary Agreement. Notwithstanding this Section 7.e, if either Party desires to use the other Party’s Intellectual Property after the
Term or outside the scope of the rights expressly granted in this Agreement or any Ancillary Agreement, the terms and conditions for that use may be agreed upon in writing by the Parties in their sole discretion. 

8. Trademarks. Altus Power grants to CBRE and its subsidiaries and affiliates a

Party’s trademark usage guidelines (a copy of which will be provided by each Party, and which may be amended from time to time under the licensing Party’s sole discretion). The use by each Party of any and all logos and trademarks licensed
pursuant to the foregoing sentence or otherwise agreed to by the Parties (the “Trademarks”) will inure to the benefit of the licensing Party and be subject to the prior written approval of the licensing Party for each requested use,
which such approval will not be unreasonably withheld or delayed; provided that each Party may use the other Party’s Trademarks in a manner that does not materially differ from a use previously approved in writing without seeking further
approval for such use; provided, further, that any such permission may be revoked by either Party upon reasonable notice to the other Party. 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. Except as set forth in an Ancillary Agreement, each Party will thereafter promptly destroy all materials in their possession containing a Trademark of the other Party (other than historical materials that are not visible to the
general public), subject to 

  
 9 

 
compliance with applicable law, and will certify to the destruction of such materials upon written request. 

9. Publications; Promotional Materials.

“Publication”) will be made without the other Party’s prior written approval. Each Party agrees to submit each Publication it proposes to make to the other Party for purposes of the other Party’s review, comment and
approval. Each Party further agrees to respond as promptly as reasonably practicable and agrees that it will not unreasonably withhold approval of a Publication; provided, that each Party may make any Publication that is consistent in tone
and substance with previous public statements, disclosures or communications jointly made by the Parties or to the extent that they have been reviewed and previously approved by both Parties. The Parties agree that they will use reasonable efforts
to coordinate any press releases relating to this Agreement or any Ancillary Agreement. 
 b. From time to
time, each Party may provide the other Party with copies of such Party’s sales and promotional materials (the “Materials”), in graphical image files, print or other media. Each Party agrees that it will request the Materials in
a timely manner, providing such other Party sufficient time to process the request. The Materials provided by one Party to the other Party will be used by such other Party solely in connection with the performance of this Commercial Arrangements.
Each Party agrees not to alter, deface or otherwise change the appearance of any Materials of the other Party without such Party’s prior written consent, including the color, character and integrity of same. All title to, and ownership of,
CBRE’s Materials and all derivative works thereof will at all times remain with CBRE, and Altus Power will ensure that all of CBRE’s Materials are adequately and correctly displayed, including any markings requested by CBRE in order to

required to discontinue using in its possession and will certify to the destruction of the Materials upon written request. 

10. Dispute Resolution. 

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. The fees and costs of the arbitrator will be shared equally by the Parties; provided that each Party
will pay its own attorneys’ fees; provided, further, that the arbitrator may award legal fees, disbursements and other expenses to the prevailing Party for such amounts as determined by the arbitrator to be appropriate. Judgment
upon the arbitrator’s award may be entered as if after trial in accordance with Delaware law. 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. 

11. Warranties and Limitations. 

a. CBRE represents and warrants to Altus Power that it is a corporation duly formed, validly existing and in
active status under the laws of the State of Delaware. The execution of this Agreement has been duly authorized by all required corporate action, and

losses, damages, liabilities, demands, actions, costs, claims and expenses, including reasonable attorney’s fees (collectively, “Losses”), asserted against or incurred by the Indemnified Party arising out of, relating to or

breach and will have a cure period of thirty (30) days, provided, further, that if at the end of such 30-day period such breach remains uncured but the Indemnifying Party has been diligently
pursuing the cure of such breach, the cure period will be extended for such time as is reasonably required for the Indemnifying Party to complete the cure so long as the Indemnifying Party continues to diligently pursue such cure). 

13. Limitation of Liability. EXCEPT FOR VIOLATION OF SECTION 6 (CONFIDENTIALITY) OR TO

 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 – 
  

	 	1)	 The CBRE Broker will submit a referral through a CBRE website which will request some specific information
(e.g., property address, client contact information, etc.) about the opportunity. 

  

	 	2)	 CBRE’s Renewable Energy Solutions team will evaluate these referrals and prioritize which referrals to
pursue and what additional information is required 

  

	 	3)	 CBRE’s Renewable team will present the opportunities to Altus who will determine which referrals are
Qualified Referrals 

 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: 

 

			
	 New-Build Solar
Systems

	 Megawatts Per Project
	  	 Referral Fee

	 <2 MW – 10 MW
	  	 $0.030/watt

	 On Portion of Sizes Above 10 MW
	  	 $0.020/watt

 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 
  

			
	 New-Build Storage
Systems

	 Megawatts Per Project
	  	 Referral Fee

	 <2 MWH – 10 MWH
	  	 $0.030/watthour [to be confirmed]

	 On Portion of Sizes Above 10 MWH
	  	 $0.020/watthour [to be confirmed]

 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. 

			
	 Secondary/Existing Solar & Storage
Systems

	 Megawatts Per Project
	  	 Referral Fee

	 <2 MWH – 10 MWH
	  	 $0.020/watt for solar and $0.020/watthour for storage [to be confirmed]

	 On Portion of Sizes Above 10 MWH
	  	 $0.015/watt for solar and $0.015/watthour for storage [to be confirmed]

 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.

 [VIA EMAIL] 

Re: Post-Merger Incentive Equity 
 Dear
Mr. Felton and Mr. Norell: 
 Altus Power, Inc. (the “Company”) is pleased to present the
incentive equity package outlined below, contingent upon consummation of an anticipated business combination (the “Transaction”) with a special purpose acquisition company (the ultimate public company being the
“PubCo”). 
 Reference is made to the Business Combination Agreement (the “Combination
Agreement”), dated as of July 12, 2021, by and among CBRE Acquisition Holdings, Inc., a Delaware corporation (“PubCo”), CBAH Merger Sub I, Inc., a Delaware corporation, CBAH Merger Sub II, LLC, a Delaware limited liability
company, Altus Power America Holdings, LLC, a Delaware limited liability company, APAM Holdings LLC, a Delaware limited liability company, and Altus Power, Inc., a Delaware corporation (the “Company”). Except as otherwise indicated,
capitalized terms used but not defined herein shall have the meanings set forth in Article I of the Combination Agreement 

Subject to, and as soon as practicable following, the consummation of the Transaction, the board of directors of PubCo (the
“Board”) or the compensation committee of the Board (the “Compensation Committee”) will grant to senior members of Company, including to Mr. Felton and Mr. Norell, time-based restricted stock
units (“RSUs”) with respect to an aggregate five percent (5%) of PubCo’s Class A Common Stock on a fully diluted basis, excluding the then-outstanding shares of PubCo Class B Common Stock or any shares of Pubco’s
Class A Common Stock into which such shares of Pubco’s Class B Common Stock are or may be convertible. The RSUs will be allocated based on the recommendation of the compensation consultant(s) to the Compensation Committee (which shall
