EXECUTION VERSION 
 INTERCOMPANY AGREEMENT

 This Intercompany Agreement (this “Agreement”) is made and entered into as of November 17, 2014 (the “Effective
Date”) by and between SunEdison, Inc., a Delaware corporation (“SunEdison” or “Holdco Buyer”), SunEdison Holdings Corporation, a Delaware corporation (“SE Holdings”), and TerraForm Power,
LLC, a Delaware limited liability company (“TERP LLC” or “Operating Buyer,” and together with Holdco Buyer, each a “Buyer,” and collectively “Buyers”). Capitalized terms used but
not defined herein shall have the meanings ascribed to such terms in the Purchase Agreement (as defined below). 
 WHEREAS, SunEdison and TERP LLC are
parties to that certain Project Support Agreement dated as of July 23, 2014 (as the same may be amended or otherwise modified from time to time, the “Project Support Agreement”); SunEdison, TERP LLC, TerraForm Power, Inc., a
Delaware corporation (“TERP Inc.”), and TerraForm Power Operating, LLC, a Delaware limited liability company (“TERP Operating”), are parties to that certain Management Services Agreement dated as of July 23,
2014 (as the same may be amended or otherwise modified from time to time, the “MSA”); and SunEdison, SE Holdings, TERP Inc. and TERP LLC are parties to that certain Interest Payment Agreement dated as of July 23, 2014 (as the
same may be amended or otherwise modified from time to time, the “Interest Payment Agreement”). 
 WHEREAS, simultaneously with the
execution of this Agreement, Buyers will enter into a Purchase and Sale Agreement (the “Purchase Agreement”) with TERP Inc., as guarantor, First Wind Holdings, LLC, a Delaware limited liability company (the
“Company”), First Wind Capital, LLC , a Delaware limited liability company and wholly owned Subsidiary of the Company (“Operating Seller”), D. E. Shaw Composite Holdings, L.L.C., a Delaware limited liability company
(“Blocker Parent”), the Company Members set forth on Schedule 1.01(a) thereto (the “Company Sellers,” and together with Blocker Parent, each a “Seller” and collectively, the
“Sellers”), and D. E. Shaw Composite Holdings, L.L.C. and Madison Dearborn Capital Partners IV, L.P., acting jointly, solely in their capacity as the representative of the Sellers for the purposes specified therein, providing for the
transactions contemplated thereby (collectively, the “Transaction”); 
 WHEREAS, the parties desire to set forth their agreement with
respect to, among other things, (a) contributions towards shared costs and expenses, (b) allocation of the up to $150,000,000 of Earnout Project Payments available to satisfy Losses that are the subject of claims made pursuant to
Section 12.02(a) of the Purchase Agreement (the “Earnout Indemnity Pool”) in case aggregate claims exceed the Earnout Indemnity Pool, (c) reimbursement by Holdco Buyer to Operating Buyer of the up to $20,000,000 of the
Escrow Funds released upon a CAFD Employee Acceleration Event pursuant to Section 2.06(d) of the Purchase Agreement, (d) reimbursement of certain excess capital expenditures that the Operating Entities may make during the first 5 years
following the Closing (“Operating Entity Capital Expenditures”), (e) the grant by SunEdison to TERP of certain call right options with respect to the Earnout Projects, and (f) the modification of certain terms of the
Interest Payment Agreement. 
 NOW, THEREFORE, in consideration of the mutual promises and covenants herein set forth, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows: 
 1. Shared Costs. Subject to the provisions of the
MSA in case the Closing does not occur, and except with respect to any fees, original issuer discounts or other costs of financings or commitments for the benefit of one or more specific parties and the costs of any advisors or consultants of one or
more specific parties, each Buyer agrees to be responsible for, and to pay, reimburse or contribute (or cause one of its Affiliates to pay, reimburse or contribute) its Proportionate Share of (a) any amounts or expenses

 
required to be paid collectively by Buyers pursuant to the Purchase Agreement in order to reach Closing, including without limitation, filing fees under the HSR Act, and (b) fees and
expenses payable to legal, technical, and accounting advisors retained to represent or advise Buyers jointly in connection with the Transaction, with “Proportionate Share” defined as a share of 65% for Holdco Buyer and 35% for
Operating Buyer. 
 2. Earnout Indemnity Pool Allocation. Each Buyer acknowledges and agrees that, in general, its sole recourse to obtain payment of
indemnifiable Losses will be through set-offs against the Earnout Indemnity Pool in accordance with the terms of the Purchase Agreement up to the full amount of such Earnout Indemnity Pool or any applicable sub-limit (as applicable, the
“Indemnity Limit”). Accordingly, Buyers agree as follows: 
 (a) Subject to clauses (b) and (c) immediately below, if an
indemnity payment is due and payable to Operating Buyer pursuant to the Purchase Agreement, Holdco Buyer agrees to set off such indemnity payment against Earnout Project Payments due to the Sellers pursuant to Section 2.04 of the Purchase
Agreement up to the Indemnity Limit, and pay the relevant amount to Operating Buyer within 30 days of such payments becoming due and payable to Operating Buyer. 

(b) If (i) indemnity payments are due to Holdco Buyer pursuant to the Purchase Agreement, but (ii) the Indemnity Limit has been reached and
(iii) this results in the inability of Holdco Buyer to offset all or part of such indemnity payments against Earnout Project Payments (the “Unrecoverable Amount”), and (iv) Operating Buyer has actually received indemnity
payments that exceed its Proportionate Share of the Earnout Indemnity Pool (the “Operating Buyer Excess Indemnification”), then Operating Buyer shall repay to Holdco Buyer an amount equal to the lesser of the Unrecoverable Amount
and the Operating Buyer Excess Indemnification within 30 days of the date such indemnity payment would have become due and payable to Holdco Buyer disregarding the Indemnity Limit. 

(c) If (i) indemnity payments are due to Operating Buyer pursuant to the Purchase Agreement, but (ii) the Indemnity Limit has been reached and
(iii) this results in an Unrecoverable Amount, and (iv) Holdco Buyer has offset indemnity claims due to Holdco Buyer against Earnout Project Payments that exceed, in the aggregate, Holdco Buyer’s Proportionate Share of the Earnout
Indemnity Pool (such excess, the “Holdco Buyer Excess Indemnification”), then Holdco Buyer shall pay to Operating Buyer an amount equal to the lesser of the Unrecoverable Amount and the Holdco Buyer Excess Indemnification within 30
days of the date such indemnity payment would have become due and payable to Operating Buyer disregarding the Indemnity Limit. 
 (d) The provisions
of this Section 2 shall not apply to any indemnification payment any of the Buyers receive that is not counted towards the Indemnity Limit. 
 3. Escrow
Acceleration Payment. The parties acknowledge and agree that, in the event that Operating Buyer is required to release any amounts from the Escrow Account to the Paying Agent as a result of a CAFD Employee Acceleration Event (the “Escrow
Acceleration Payment”), Holdco Buyer shall, upon receipt of a written demand from Operating Buyer, together with reasonable documentation that Operating Buyer would have had the right to withdraw funds from the Escrow Account had there not
been an Escrow Acceleration Payment (a “CAFD Claim”), pay (or cause one of its Affiliates to pay) an amount equal to the CAFD Claim to Operating Buyer within 30 days of such written demand. 

4. Non-Payment. Each Buyer acknowledges and agrees that, in the event that a Buyer does not pay its portion of the Total Purchase Price in accordance with the
Purchase Agreement (the “Non-Paying Buyer,” and such failure to pay, a “Non-Payment Event”), the other Buyer shall have no recourse against the Non-Paying Buyer for liabilities incurred as a result of a Non-Payment
Event, including, without 

  
 -2- 

 
limitation, all cost, fees and expenses incurred in connection with a Non-Payment Event; provided that nothing in this foregoing shall affect the obligations of SunEdison under the MSA to pay
fees or expenses in case Closing does not occur; and provided, further, that to the extent that a Buyer has liability to any Seller in connection with the Purchase Agreement or any other agreement entered into in connection with the Transactions
(collectively, the “Transaction Agreements”) that would not have existed but for a breach of such Transaction Agreement by such other Buyer, then such other Buyer shall indemnify the Buyer not in breach of such Transaction Agreement
for any liability incurred by such non-breaching Buyer. 
 5. Excess CAPEX Reimbursement. 

(a) The parties acknowledge and agree that the allocation of payments and liabilities with respect to the Transaction among the Buyers assumes that any
Operating Entity Capital Expenditures to be made in the five years after Closing (the “Reimbursement Period”) do not exceed the amounts set forth in the email titled “Capex summary for Hurricane” sent by Francisco Perez
Gundin to Brian Wuebbels and Martin Truong on November 17, 2014 at 5:12 pm Eastern time (the “CAPEX Plan,”). HoldCo Buyer therefore agrees that, to the extent Operating Buyer, in its reasonable discretion, determines that
Operating Entity Capital Expenditures are necessary or appropriate in accordance with good engineering practice in excess of the Plan, (“Excess Capital Expenditures”) and actually incurs such Excess Capital Expenditures during the
Reimbursement Period, Holdco Buyer shall reimburse Operating Buyer for any such Excess Capital Expenditures up to an aggregate amount of $ 50 million. 

(b) Characterization of Payments. Any payments made by Holdco Buyer or any of its Affiliates with respect to Excess Capital Expenditures shall be
treated as a contribution by SunEdison (or its applicable affiliate) to the capital of SE Holdings, followed by a contribution by SE Holdings to the capital of Operating Buyer. However, none of SunEdison, SE Holdings or their respective affiliates
shall have any rights, at any time, to reimbursement of any payments made with respect to Excess Capital Expenditures. 
 6. Earnout Projects as Call Right
Assets. 
 (a) The Parties hereby agree that, subject to the provisions of this Section 6, all Earnout Projects and the projects set forth on
Exhibit A attached hereto (collectively, the “Additional Call Right Projects”) shall be deemed to be “Call Right Assets” as defined in the Project Support Agreement, and be subject to all provisions of the Project Support
Agreement relating to Call Right Assets. 
 (b) Notwithstanding the foregoing, Holdco Buyer may sell, contribute or otherwise transfer its rights in
any Additional Call Right Project to an entity (a “Dropdown Warehouse”) that the parties may set up with third party investors and / or financial institutions for the purpose of providing financing for the construction and
operation of such Earnout Project, as long as (i) TERP LLC or any of its subsidiaries shall have a call right to acquire such Additional Call Right Project from the Dropdown Warehouse following its completion, and (ii) the terms of
such call right, any right the Dropdown Warehouse may have to put the relevant Additional Call Right Project to TERP LLC or any of its subsidiaries, or any other material right of the Dropdown Warehouse with respect to such Additional Call
Right Project that may adversely affect TERP, Inc. or any of its subsidiaries shall have been approved by TERP LLC prior to such sale, contribution or other transfer (with the approval of the Conflicts Committee, as defined below). 

(c) For the avoidance of doubt, (i) neither SunEdison nor Holdco Buyer are making any representations regarding the Estimated CAFD (as defined in
the Project Support Agreement) to be generated by any of the Additional Call Right Projects, (ii) no Estimated CAFD from any Additional Call  

  
 -3- 

 
Right Project shall count towards SunEdison’s CAFD Commitment under the Project Support Agreement and (iii) except pursuant to a separate agreement entered into with the approval
of the Conflicts Committee, neither TERP, Inc., nor TERP LLC, nor TERP Operating or any of their subsidiaries shall have any obligation to make or liability for making any payments to any person with respect to the Additional Call Right
Projects. 
 7. Modifications to Interest Payment Agreement. The parties agree that, effective at the closing of the financing agreements that will replace the
Credit Agreement (as defined in the Interest Payment Agreement) at Closing (the “Replacement Financing Agreement”), the Interest Payment Agreement shall be amended so that SunEdison will provide the same level of support to TERP
Operating (or its relevant affiliate) as is currently provided to TERP Operating pursuant to the Interest Payment Agreement, notwithstanding the repayment of the Term Loan (as defined in the Interest Payment Agreement). 

8. O&M Agreements for Certain Projects. The parties agree that Sec. 2.4.2 (Assumption of O&M and Asset Management Contracts) of the Management
Services Agreement shall apply to the projects set forth on Exhibit B hereto, provided that for the years 2015 through 2019, the aggregate fee charged by the relevant affiliate of SunEdison with respect to labor costs under the relevant O&M
contracts shall not exceed the amount set forth for the relevant year. 
 9. Representations and Warranties. Each party hereby represents and warrants to the
other parties that: 
 (a) it is validly organized and existing under the laws of the State of Delaware; 

(b) it has the power, capacity and authority to enter into this Agreement and to perform its duties and obligations hereunder; 

(c) it has taken all necessary action to authorize the execution, delivery and performance of this Agreement; 

(d) the execution and delivery of this Agreement by it and the performance by it of its duties obligations hereunder do not and will not contravene,
breach or result in any default under its Organizational Documents, or under any mortgage, lease, agreement or other legally binding instrument, permit or applicable law to which it is a party or by which any of its properties or assets may be
bound, except for any such contravention, breach or default which would not have a material adverse effect on its business, assets, financial condition or results of operations taken as a whole; 

(e) no authorization, consent or approval, or filing with or notice to any governmental body or authority or other person is required in connection with
the execution, delivery or performance by it of this Agreement; and 
 (f) this Agreement constitutes its valid and legally binding obligation,
enforceable against it in accordance with its terms, subject to: (i) applicable bankruptcy, insolvency, moratorium, fraudulent conveyance, reorganization and other laws of general application limiting the enforcement of creditors’ rights
and remedies generally; and (ii) general principles of equity, including standards of materiality, good faith, fair dealing and reasonableness, equitable defenses and limits as to the availability of equitable remedies, whether such principles
are considered in a proceeding at law or in equity. 
 10. Term; Termination. 

(a) Term. This Agreement shall become effective as of the Effective Date and shall 

  
 -4- 

 
terminate on the date on which all obligations hereunder shall have been performed in full and amounts due by Buyers hereunder shall have been paid in full, unless terminated earlier as set forth
in this Agreement (the “End Date). 
 (b) Termination. Notwithstanding Section 9(a), this Agreement may be terminated prior to
the End Date as follows: 
 (i) The parties may terminate this Agreement by mutual written agreement. 

(ii) This Agreement shall automatically terminate upon a Change in Control of TERP Inc. As used herein, “Change of Control” means, the
occurrence of any of the following: (A) a “Person” (as such term is used in Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended, but specifically excluding SE Holdings and its Affiliates) becoming a
beneficial owner, directly or indirectly, of equity representing fifty percent (50%) or more of the total voting power of TERP Inc.’s then outstanding equity capital; (B) TERP Inc or TERP LLC merging into, consolidating with or
effecting an amalgamation with another Person, or merging another Person into TERP Inc or TERP LLC, on a basis whereby less than fifty percent (50%) of the total voting power of the surviving Person immediately after such merger, consolidation
or amalgamation is represented by equity held directly or indirectly by former equity holders of (and in respect of their former equity holdings in) TERP Inc immediately prior to such merger, consolidation or amalgamation; and (C) TERP LLC
directly or indirectly selling, transferring or exchanging all, or substantially all, of its assets to another Person unless greater than fifty percent (50%) of the total voting power of the transferee receiving such assets is directly or
indirectly owned by the equity holders of TERP LLC in respect of their former equity holdings in TERP LLC immediately prior to transfer. 
 (iii)
Either Buyer may terminate this Agreement immediately if either Buyer makes a general assignment for the benefit of its creditors, institutes proceedings to be adjudicated voluntarily bankrupt, consents to the filing of a petition of bankruptcy
against it, is adjudicated by a court of competent jurisdiction as being bankrupt or insolvent, seeks reorganization under any bankruptcy law or consents to the filing of a petition seeking such reorganization or has a decree entered against it by a
court of competent jurisdiction appointing a receiver liquidator, trustee or assignee in bankruptcy or in insolvency. 
 (c) This Agreement may only
be terminated pursuant to Section 8(b)(i) or 8(b)(iii) above by TERP LLC with the prior approval of a majority of the members of the Conflicts Committee. “Conflicts Committee” means a committee of the board of directors (or
equivalent body) of TERP Inc, established in accordance with TERP Inc.’s certificate of incorporation and by-laws, in each case as then in effect, made up of directors that are “independent” of TERP Inc. and its affiliates. For
purposes of this definition, “independent” means a person who satisfies the independence requirements of the rules and regulations of the applicable stock exchange, the U.S. Securities and Exchange Commission and TERP Inc.’s
Organizational Documents. The Conflicts Committee shall initially be the Corporate Governance and Conflicts Committee of the board of directors of TERP, Inc. 
 11.
Amendment; Waiver. The parties may amend this Agreement only by a written agreement signed by the parties and that identifies itself as an amendment to this Agreement, provided that, except as expressly provided in this Agreement, no
amendment or waiver of this Agreement will be binding unless the prior approval of a majority of the members of the Conflicts Committee is obtained and the amendment or waiver is executed in writing by the party to be bound thereby. No waiver of any
provision of this Agreement will constitute a waiver of any other provision nor will any waiver of any provision of this Agreement constitute a continuing waiver unless otherwise expressly provided. A party’s failure or delay in exercising any
right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

 18. Invalidity of Provisions. Each of the
provisions contained in this Agreement is distinct and severable and a declaration of invalidity or unenforceability of any such provision or part thereof by a court of competent jurisdiction will not affect the validity or enforceability of any

Agreement by reason of any such warranty, representation, opinion, advice or assertion of fact. Accordingly, there will be no liability, either in tort or in contract, assessed in relation to any such warranty, representation, opinion, advice or

as Administrative Agent (“Administrative Agent”), and is made with reference to that certain CREDIT AND GUARANTY AGREEMENT dated as of July 23, 2014 (as amended through the date hereof, the “Credit
Agreement”) by and among Borrower, TERRAFORM POWER, LLC, a Delaware limited liability company, the subsidiaries of Borrower named therein, the Lenders, the Administrative Agent, Collateral Agent and the other Agents named therein.
Capitalized terms used herein without definition shall have the same meanings herein as set forth in the Credit Agreement after giving effect to this Amendment. 

RECITALS 
 WHEREAS,
pursuant to Section 10.5 of the Credit Agreement, Borrower has requested that Administrative Agent agree to certain technical amendments to the Credit Agreement as provided for herein; and

 NOW, THEREFORE, in consideration of the premises and the agreements, provisions and covenants herein contained, the parties hereto
agree as follows: 
 SECTION I. AMENDMENTS TO CREDIT AGREEMENT 

A. Amendment to Section 1.1. Clause (v) of the definition of “Permitted M&A Transaction” in Section 1.1 of
the Credit Agreement is hereby amended to add the bolded and underlined text as set forth below: 
 “(v) Borrower shall be in
compliance with the financial covenants set forth in Section 6.7 by giving pro forma effect to such acquisition as if such acquisition had occurred on the first day of the current Fiscal Quarter, and by deeming historical financial performance
of the acquired Person or property for such Fiscal Quarter and each Fiscal Quarter prior thereto to be equal to the projected financial performance for the corresponding Fiscal Quarter in the following calendar year (as determined in
the good faith reasonable judgment of Borrower); and” 
 A. Amendment to Section 2.4. Section 2.4(a) of the Credit
Agreement is hereby amended to add the bolded and underlined text and delete the bolded and stricken text as set forth below: 
 “(a)
Letters of Credit. During the Revolving Commitment Period, subject to the terms and conditions hereof, Issuing Bank agrees to issue Letters of Credit for the account of Holdings, Borrower or any of Borrower’s
subsidiariesBorrower in the aggregate amount up to but not exceeding the Letter of Credit Sublimit; provided, (i) each Letter of Credit shall be denominated in Dollars or one or more Alternative Currencies;
(ii) the stated amount of each Letter of Credit shall not be less than $250,000 or such lesser amount as is acceptable to Issuing Bank; (iii) after giving effect to such issuance, in no event shall the Total Utilization of Revolving

additional period; provided, Issuing Bank shall not extend any such Letter of Credit if it has received written notice that an Event of Default has occurred and is continuing at the time Issuing Bank must elect to allow such extension; provided
further, if any Lender is a Defaulting Lender, Issuing Bank shall not be required to issue any Letter of Credit unless Issuing Bank has entered into arrangements satisfactory to it and Borrower to eliminate Issuing Bank’s risk with respect to
the participation in Letters of Credit of the Defaulting Lender. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement
submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.”
