THE PURCHASERS NAMED ON EXHIBIT A HERETO WITH RESPECT TO EACH CLASS OF NOTES (the “Initial Purchasers” and, together with any Additional Purchasers, the “Purchasers”)

March 28, 2019

Ladies and Gentlemen:

Sunnova RAYS I Issuer, LLC, a Delaware limited liability company (the “Issuer”), has duly authorized the issuance and sale of asset-backed notes (collectively, the “Notes”) to be authorized, issued and authenticated pursuant to an Indenture, dated as of the date hereof (together with any Indenture Supplement, the “Indenture”), by and among the Issuer and Wilmington Trust, National Association, as indenture trustee (in such capacity, the “Indenture Trustee”). Payments and transfers of the Notes will be subject to the terms and conditions of the Indenture and the Notes. Capitalized terms used but not otherwise defined herein shall have the respective meanings set forth in the Indenture, a copy of which has been provided to the Purchasers. Any reference in this Note Purchase Agreement, as supplemented by any Note Purchase Agreement Supplement substantially in the form of Exhibit C hereto (each a “NPA Supplement” and, collectively, this “Agreement”) to “herein”, “hereto”, “hereunder” or terms of similar import shall refer collectively to this Agreement, each NPA Supplement, and all schedules, exhibits and other attachments to this Agreement and each NPA Supplement. The Purchasers have agreed, severally but not jointly, to purchase the applicable Class of Notes from time to time as specified herein. The Notes purchased by the Purchasers hereunder will be represented by certificated Notes in definitive, fully registered form.

For good and valuable consideration, the Issuer hereby agrees with each Purchaser as follows:

Section 1. Purchase, Sale, Payment and Delivery of the Notes.

(a) At any time and from time to time, but in no event more than once per month and no more than two times in any calendar quarter, prior to the first anniversary of the date hereof, the Issuer may, at its option, offer Notes of any Class and Series for sale to the Purchasers under this Agreement in one or more issuances by delivering a draft NPA Supplement to the Purchasers no less than seven (7) Business Days prior to the Closing Date set forth in such NPA Supplement; provided that (i) the principal amount of any series of Class A Notes issued hereunder shall not be less than $25 million (or, if less, the maximum remaining amount of Notes available to be issued pursuant to clause (ii) of this paragraph (a)), (ii) the aggregate principal amount of Notes of all Series purchased hereunder shall not exceed $403,000,000 and (iii) either (A) such Notes will, for U.S. federal income tax purposes, have the same issue price and issue date as do any Notes that are Outstanding at that time, or (B) such Notes will have a CUSIP or private placement number different from that of any Notes that are Outstanding at that time (or other similar tracking condition).

(b) On the Closing Date set forth in such NPA Supplement, on the terms and subject to satisfaction of the conditions set forth in this Agreement (including Section 4), the Indenture and the other Transaction Documents, the Issuer shall issue and sell, and each Purchaser shall severally purchase its Pro Rata Share of, the Notes of the applicable Class and Series at the

time and place specified in the related NPA Supplement, for the Class A Notes, at the issuance price equal to 100% of the principal value of such Class A Notes, and for the Class B Notes, at the issuance price set forth in the related NPA Supplement; provided that, the aggregate principal amount of all Class A Notes or Class B Notes, as applicable, purchased by each Purchaser shall not exceed the amount set forth opposite such Purchaser’s name on Exhibit A hereto under “Maximum Class A Notes to be Purchased” or “Maximum Class B Notes to be Purchased”, as applicable. On any date of determination, a Purchaser’s “Pro Rata Share” shall, with respect to any Class of Notes, equal a percentage determined by dividing the amount set forth opposite such Purchaser’s name on Exhibit A hereto under “Maximum Class A Notes to be Purchased” or “Maximum Class B Notes to be Purchased”, as applicable, by the sum of the amounts set forth opposite the names of all Purchasers under Maximum Class A Notes to be Purchased” or “Maximum Class B Notes to be Purchased”, as applicable.

Section 2. Representations, Warranties and Covenants of the Sunnova Parties. Each of the Issuer, the Depositor and Sunnova RAYS I Management, LLC (collectively, the “Sunnova Parties”) represents, warrants, covenants and agrees with the Purchasers that, on the date hereof and as of the applicable Closing Date:

(a) Such Person is a limited liability company validly existing and in good standing under the laws of the jurisdiction of its organization, with limited liability company power and authority to execute, deliver and perform its obligations under each of the Transaction Documents to which it is a party. Such Person is duly qualified to do business as a foreign business entity and is in good standing in all jurisdictions in which the ownership or lease of property or the conduct of its business as currently conducted, or as contemplated under the Transaction Documents to which it is a party, requires such qualifications, except those jurisdictions in which failure to be so qualified would not reasonably be expected to have a Material Adverse Effect.

(b) The execution, delivery and the performance by such Person of its obligations under the Transaction Documents to which it is a party have been duly authorized by all necessary limited liability company action on the part of such Person, and the related authorizing resolutions and such authorizations and approvals are in full force and effect and have not been amended, modified or rescinded except as may have been agreed in writing by the Purchasers. The Notes have been duly authorized by the Issuer and, when the Notes are authenticated, delivered and paid for pursuant to this Agreement, such Notes will have been duly executed, authenticated, issued and delivered and will constitute valid and legally binding obligations of the Issuer entitled to the benefits provided by the Indenture, and enforceable in accordance with terms and conditions therein, subject, as to enforcement, to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect affecting the enforcement of creditors’ rights in general, and except as such enforceability may be limited by general principles of equity (whether considered in a suit at law or in equity). When executed and delivered by each Sunnova Party, each of the Transaction Documents to which it is a party will constitute the legal, valid and binding obligation of such Person, enforceable in accordance with its terms, subject, as to enforcement, to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect affecting the enforcement of creditors’ rights in general, and except as such enforceability may be limited by general principles of equity (whether considered in a suit at law or in equity).

(c) No form of general solicitation or general advertising was used by any such Person in connection with the offer and sale of any Notes. No potential investors who were not institutional investors were solicited or otherwise approached by any Sunnova Party or any representative of any of them for the purpose of offering any Notes for sale. No such Person has offered or sold, or will offer or sell, any Notes in any manner that would render the issuance and sale of such Notes a violation of the Securities Act or state blue sky laws, or require registration pursuant thereto, nor has any such Person authorized, nor will any such Person authorize, any other Person to act in such manner.

(d) Assuming that the representations, warranties and covenants of each Purchaser contained in this Agreement are true and correct in all material respects and have been and will be complied with in all material respects and that the Notes are offered and sold in accordance with the applicable Transaction Documents, no registration of any Notes under the Securities Act is required for the offer, sale and delivery of the Notes at the time and in the manner contemplated by this Agreement and the Indenture.

(e) All of the representations and warranties made by such Person in the Transaction Documents to which it is a party are true and correct in all material respects as of each Closing Date, other than representations and warranties with respect to matters set forth on Schedule I of the Sale and Contribution Agreement that refer to the related Cut-Off Date or other matters that refer to a specific date, which shall be true and correct in all material respects on and as of such related Cut-Off Date or other specified date.

(f) None of the Sunnova Parties is in breach of or in default under, (i) any applicable constitutional provision, law or rule or regulation, (ii) its organizational documents, (iii) any applicable judgment, order or decree or (iv) any trust agreement, loan agreement, indenture, bond, note, resolution, ordinance, agreement or other instrument to which such Person is a party or to which such Person or any of its properties or other assets is otherwise subject, and no event has occurred and is continuing which, with the passage of time or the giving of notice, or both, would constitute a default or event of default under any such instrument, except, in each case, as would not reasonably be expected to have a Material Adverse Effect. The authorization, execution and delivery by each Sunnova Party of the Transaction Documents to which it is a party and performance by such Person of the obligations on its part to be performed under such Transaction Documents does not and will not (i) conflict with or constitute a material breach of or material default under (A) any applicable constitutional provision, law or rule or regulation, (B) such Person’s organizational documents, (C) any applicable judgment or decree or (D) any license, permit, trust agreement, loan agreement, indenture, bond, note agreement or other instrument to which such Person (or any of its officers in their respective capacities as such) is subject, or by which it or any of its properties is bound, or (ii) result in the creation or imposition of any lien, charge or other security interest or encumbrance of any nature whatsoever upon any of its assets or properties or under the terms of any such law, regulation or instrument, except for Permitted Liens.

(g) All written information contained in the Transaction Documents and any other documents, reports, financial models or other written information provided to the Purchasers, in each case, prepared by such Person or was prepared by a third party on behalf of such Person in connection with the transactions contemplated by the Transaction Documents (collectively, the

“Information”) fairly describe as of its respective date, in all material respects, the Transaction, the Trust Estate and the general nature of the business and principal assets of the Sunnova Parties (including the Financing Fund Documents but excluding any term sheet with respect to the Transaction Documents which are superseded by the Transaction Documents). The Information, taken as a whole, does not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(h) There is no fact known to such Person that materially adversely affects or, so far as such Person can now reasonably foresee, will materially adversely affect the ability of such Person, any Managing Member or any Financing Fund to perform its respective obligations under any Transaction Document to which it is a party.

(i) Annex B to each NPA Supplement sets forth a complete and correct list of all Managing Member Interests contributed to the Issuer on the date thereof and the related Financing Funds, showing, as to each such Person, as of the date thereof, the name thereof, the jurisdiction of its organization, and the percentage of shares of each class of its capital stock or similar equity interests outstanding owned by the Issuer or the related Managing Member, as applicable. There are no outstanding contracts, options, warrants, instruments, documents or agreements binding upon the Depositor or Issuer granting to any Person or group of Persons any right to purchase or acquire any Managing Member Membership Interests or any Financing Fund Interests, other than, with respect to any Financing Fund Interests, the related Financing Fund Documents made available to the Purchasers on or prior to the date the related NPA Supplement was delivered.

(j) All of the outstanding Managing Member Membership Interests of the Managing Members listed on Annex B to the NPA Supplements have been contributed and/or sold to the Issuer, free and clear of any Lien other than Permitted Liens. The related Managing Member owns all of the issued and outstanding Financing Fund Interests in each Financing Fund.

(k) All federal, state and local tax returns and reports of each Sunnova Entity required to be filed have been timely filed (or each such Person has timely filed for an extension and the applicable extension has not expired), and all Taxes, assessments, and other governmental charges (including any payments in lieu of Taxes) upon such Persons and upon its properties, assets, income, profits, businesses and franchises which are due and payable have been timely paid except (i) to the extent the same are being contested in accordance with Section 3.01(d) of the Indenture or (ii) to the extent the effect of the failure to file such tax return and reports or to pay such Taxes, assessments, and other governmental charges would not reasonably be expected to result in a Material Adverse Effect. None of the Issuer, any Managing Member nor any Financing Fund is responsible for material income or franchise tax (other than standard payments owed to Delaware or any other state where such Person is qualified to do business). The Issuer and each of the Managing Members is, and shall at all relevant times continue to be, a “disregarded entity” within the meaning of U.S. Treasury Regulation § 301.7701-3 that is disregarded as separate from a United States person (within the meaning of Section 7701(a)(30) of the Code) for U.S. federal income tax purposes. None of the Issuer, Managing Members or Financing Funds is, nor shall become, an association, a publicly traded partnership or a taxable mortgage pool that is taxable as a corporation for U.S. federal income tax purposes. None of the Issuer, Managing Members or Financing Funds is, nor shall become, subject to any tax in any jurisdiction outside the United States.

(l) There is no action, suit or proceeding at law or in equity, before or by any court, government agency, public board or body (collectively and individually, an “Action”) pending with respect to which any Sunnova Party has been served with process which could reasonably be expected to result in a Material Adverse Effect.

(m) No authorization or approval or other action by, and no notice to or filing with, any Governmental Authority is required in connection with the execution, delivery or performance by any Sunnova Party of any Transaction Document to which it is a party except (i) those that have been obtained, filed or made on or prior to the applicable Closing Date, (ii) such as may be required under state securities or blue sky laws in any jurisdiction in connection with the purchase and sale of the Notes by the Purchasers and (iii) if not required to be obtained, filed or recorded on or prior to the applicable Closing Date, that will be obtained, filed or made when required. No consent or approval of any other Person (including a Tax Equity Investor) is required in connection with the execution, delivery or performance by any Sunnova Party of any Transaction Document to which it is a party except those that have been obtained, filed or made on or prior to the applicable Closing Date.

(n) None of the Sunnova Parties is engaged in the business of extending credit for the purpose of purchasing or carrying margin stock, and no proceeds from the transactions contemplated hereby, directly or indirectly, will be used for a purpose that violates, or would be inconsistent with, Regulation T, U or X promulgated by the Federal Reserve Board from time to time. As used in this Section 3(n), the terms “margin stock” and “purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U.

(o) All Third-Party Diligence Reports are, as among the parties to this Agreement, deemed to have been obtained by the Issuer pursuant to Rule 15Ga-2 and Rule 17g-10 of the Exchange Act and all legal obligations with respect to any such Third-Party Diligence Report have been timely complied with and will continue to be timely complied with. “Third-Party Diligence Report” means any report generated by a third party with respect to due diligence services obtained by any Sunnova Party within the meaning of Rule 15Ga-2 and Rule 17g-10 of the Exchange Act.

(p) None of the Sunnova Parties has requested (or caused any Person to request) any third party due diligence services, other than the third party due diligence services relating to the Third-Party Diligence Report(s) set forth in Annex F to any NPA Supplement. True and complete copies of each Third-Party Diligence Report have been provided to each Purchaser prior to the furnishing or filing of such report or portion thereof with the U.S. Securities and Exchange Commission or on its 17g-5 website, as applicable.

(q) (i) The Issuer is the owner of the Conveyed Property contributed and sold to it by the Depositor free and clear of all Liens other than Permitted Liens. Each Managing Member is the owner of the related Financing Fund Interests free and clear of all Liens other than Permitted Liens. All assets included in the Trust Estate are free and clear of all Liens other than Permitted Liens. Any and all financing statements and other documents or instruments necessary

to perfect the Indenture Trustee’s Lien on the Trust Estate have been filed (or arrangements have been made for such filings to occur within the time permitted under the Indenture or the Managing Member Pledge Agreement) in each filing office necessary for such purpose, and all filing fees and taxes, if any, payable in connection with such filings have been paid in full; and

(ii) The Indenture and the other Transaction Documents create a valid Grant of a security interest to the Indenture Trustee for the benefit of the Noteholders in all right, title and interest of the Issuer in the Trust Estate owned by it that is of a type in which a security interest may be created under Article 9 of the New York UCC. To the extent the UCC does not apply to the perfection of such security interest, all notices, filings and other actions (including the delivery of certificates representing the Managing Member Membership Interests and the instruments of transfer executed in blank) required by all Applicable Law have been taken to perfect such security interest and lien in the assets of the Trust Estate subject to Permitted Liens.

(r) Immediately after giving effect to the purchase of any Notes, each Sunnova Party will be solvent.

(s) None of the Sunnova Parties has indebtedness for money borrowed by such entity other than such indebtedness incurred pursuant to the Transaction Documents.

(t) Neither the Depositor nor the Issuer has agreed or consented to cause or permit any of its property, whether now owned or hereafter acquired, to be subject to a Lien or to cause or permit in the future (upon the happening of a contingency or otherwise) any of its property, whether now owned or hereafter acquired, to be subject to a Lien, in each case other than Permitted Liens.

(u) None of the Sunnova Parties is an “investment company” required to register under the 1940 Act.

None of the Sunnova Parties has been notified that its name appears or may in the future appear on a state list of Persons that engage in investment or other commercial activities in Iran or any other country that is subject to U.S. Economic Sanctions or Canadian Economic Sanctions Laws.

(w) No part of the proceeds from the sale of the Notes hereunder constitutes or will constitute funds obtained on behalf of any Blocked Person or will otherwise be used by the Issuer, directly or indirectly, (i) in connection with any investment in, or any transactions or dealings with, any Blocked Person, or (ii) otherwise in violation of U.S. Economic Sanctions.

(x) None of the Sunnova Parties (i) has been found in violation of, charged with, or convicted of, money laundering, drug trafficking, terrorist-related activities or other money laundering predicate crimes under the Currency and Foreign Transactions Reporting Act of 1970 (otherwise known as the Bank Secrecy Act), the USA PATRIOT Act or any other United States, Canada or other law or regulation governing such activities (collectively, “Anti-Money Laundering Laws”) or any U.S. Economic Sanctions violations or violations of Canadian Economic Sanctions Laws, (ii) to any Sunnova Party’s knowledge or, after making due inquiry, is under investigation by any Governmental Authority for possible violation of Anti-Money Laundering Laws or any U.S. Economic Sanctions violations or violations of Canadian Economic Laws, (iii) has been assessed civil penalties under any Anti-Money Laundering Laws or any U.S. Economic Sanctions or Canadian Economic Sanctions Laws, or (iv) has had any of its funds seized or forfeited in an action under any Anti-Money Laundering Laws. Each Sunnova Party has established procedures and controls which it reasonably believes are adequate (and otherwise comply with applicable law) to ensure that such Person is and will continue to be in compliance with all applicable current and future Anti-Money Laundering Laws and U.S. Economic Sanctions and Canadian Economic Sanctions Laws.

(y) (i) None of the Sunnova Parties (A) has been charged with, or convicted of bribery or any other anti-corruption related activity under any applicable law or regulation in a U.S. or any non-U.S. country or jurisdiction, including but not limited to, the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act 2010 (collectively, “Anti-Corruption Laws”), (B) to any Sunnova Party’s knowledge, after making due inquiry, is under investigation by any U.S. or non-U.S. Governmental Authority for possible violation of Anti-Corruption Laws, (C) has been assessed civil or criminal penalties under any Anti-Corruption Laws or (D) has been or is the target of sanctions imposed by the United Nations, the European Union or Canada; and (ii) to any Sunnova Party’s knowledge, after making due inquiry, such Person has not, within the last five years, directly or indirectly offered, promised, given, paid or authorized the offer, promise, giving or payment of anything of value to a Governmental Authority official or a commercial counterparty for the purposes of: (A) influencing any act, decision or failure to act by such Governmental Authority official in his or her official capacity or such commercial counterparty, (B) inducing a Governmental Authority official to do or omit to do any act in violation of the Governmental Authority official’s lawful duty, or (C) inducing a Governmental Authority official or a commercial counterparty to use his or her influence with a government or instrumentality to affect any act or decision of such government or entity; in each case in order to obtain, retain or direct business or to otherwise secure an improper advantage in violation of any applicable Anti-Corruption Law or which would cause any holder to be in violation of any Anti-Corruption Law applicable to such holder.

(z) No part of the proceeds from the sale of the Notes will be used, directly or indirectly, for any unlawful payments, including bribes, to any Governmental Authority official or commercial counterparty in order to obtain, retain or direct business or obtain any improper advantage in violation of applicable Anti-Corruption Law. Each Sunnova Party has established procedures and controls which it reasonably believes are adequate (and otherwise comply with applicable law) to ensure that such Person is and will continue to be in compliance with all applicable current and future Anti-Corruption Laws.

(ff) The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is subject to the prohibitions of section 406 of ERISA or in connection with which a tax could be imposed pursuant to section 4975(c)(1)(A)-(D) of the Code. The representation by the Sunnova Parties to each Purchaser in the first sentence of this Section 2(ff) is made in reliance upon and subject to the accuracy of each Purchaser’s representations in Section 3(i) and Section 3(j) as to the sources of the funds to be used to pay the purchase price of the Notes to be purchased by such Purchaser.

(hh) The Issuer shall provide such information and documentation as may reasonably be requested by any Purchaser from time to time for purposes of compliance by each Sunnova Party with applicable laws and any policy or procedure implemented by the Issuer to comply with the 31 C.F.R. § 1010.230 (the “Beneficial Ownership Regulation”). To the extent required by the Beneficial Ownership Regulation, the Issuer shall, as soon as practicable, and in

any event within five (5) Business Days after an officer of the Issuer obtains knowledge thereof, notify the Purchasers of any change in the information provided in any Beneficial Ownership Certificate that would result in a change to the list of beneficial owners identified therein and, in connection with each such notice (and at the same time such notice is provided), deliver to the Purchasers a new Beneficial Ownership Certificate, in form and substance reasonably acceptable to the Purchasers.

Section 3. Representations, Warranties and Covenants of each Purchaser. Each Purchaser, severally and not jointly, represents and warrants to, and agrees with the Issuer, on each Closing Date, that:

(a) Such Purchaser (i) is sufficiently experienced in financial and business matters to be capable of evaluating the merits and risks involved in purchasing the Notes and to make an informed decision relating thereto, (ii) has the ability to bear the economic risk of such Purchaser’s investment in such Notes, (iii) has been furnished with, and has carefully reviewed, all materials that it considers relevant to an investment in such Notes and (iv) has had a full opportunity to ask questions of and receive answers from each Sunnova Party and any Persons acting on their behalf relating to such Notes and an investment therein.

(b) Such Purchaser acknowledges that no market for the Notes currently exists. Such Purchaser acknowledges that it may find it impossible to liquidate its investment in the Notes at a time when it may be desirable to do so, or at any other time.

(c) No Person (i) has acted, directly or indirectly, as a broker, finder or financial advisor for such Purchaser in connection with the transactions contemplated by this Agreement (as supplemented by the NPA Supplements), or (ii) is entitled to any fee or commission or like payment in respect thereof for which, in respect of both clauses (i) and (ii), the Depositor or the Issuer may be liable.

(d) Such Purchaser has the requisite power and authority to execute and deliver this Agreement (if such Closing Date is the initial Closing Date) and the related NPA Supplement, and to purchase the Notes in accordance herewith, has duly authorized such execution, delivery and purchase, and has duly executed and delivered this Agreement (if such Closing Date is the initial Closing Date) and such NPA Supplement.

(e) Such Purchaser is acquiring the Notes as principal for its own account (or for one or more accounts each holder of which is both a Qualified Purchaser (defined below) and an Institutional Accredited Investor (defined below), and with respect to which accounts the Purchaser has investment discretion) for investment and not with a view toward, or for sale in connection with any distribution thereof in violation of the registration requirements of the Securities Act.

(f) Such Purchaser understands that the Notes have not been and will not be registered under the Securities Act in reliance upon exemptions from the registration requirements thereof, and, if in the future it decides to offer, resell, pledge or otherwise transfer the Notes, such Notes may be offered, resold, pledged or otherwise transferred only in accordance with applicable state and federal securities laws, the provisions of the Indenture (as supplemented by the related

Indenture Supplements and any other supplemental indentures) and the restrictive legends that the Purchaser understands such Notes will bear on such Notes, including without limitation the requirement for written certifications. In particular, such Purchaser understands that the Notes may be transferred only to a person that is both a Qualified Purchaser (with respect to the Issuer) and an Institutional Accredited Investor. Such Purchaser acknowledges that no representation is made as to the availability of any exemption under the Securities Act or any state securities laws for resale of the Notes. Such Purchaser understands that the Issuer is relying upon the truth and accuracy of, and such Purchaser’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of such Purchaser set forth in this Agreement in order to determine the availability of such exemptions.

(g) Such Purchaser has a properly completed and signed Internal Revenue Service Form W-9, Form W-8BEN, W-8BEN-E, W-8ECI, or W-8IMY, as applicable (or applicable successor form) and has delivered it to the Indenture Trustee. By the purchase of the Notes or its acceptance of a beneficial interest therein, such Purchaser acknowledges and agrees that, for all tax purposes, it is entering into this Agreement with the intention that the Notes will be characterized as indebtedness and shall treat the Notes as indebtedness, unless otherwise required by applicable law. The Purchaser also acknowledges and agrees that interest on the Notes will be treated as United States source interest, and, as such, United States withholding tax may apply. Each Purchaser of a Class B Note, and any Person that has or will have a direct or indirect ownership interest in it, is not and will not become a Disqualified Entity.

(h) Such Purchaser is a “qualified purchaser” as defined in Section 2(a)(51) of the 1940 Act (“Qualified Purchaser”) and an “accredited investor” as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act (“Institutional Accredited Investor”).

(i) Each Purchaser of a Class A Note severally represents that at least one of the following statements is an accurate representation as to each source of funds (a “Source”) to be used by such Purchaser to pay the purchase price of the Notes to be purchased by such Purchaser hereunder:

(i) the Source is an “insurance company general account” (as the term is defined in the United States Department of Labor’s Prohibited Transaction Exemption (“PTE”) 95-60) in respect of which the reserves and liabilities (as defined by the annual statement for life insurance companies approved by the NAIC (the “NAIC Annual Statement”)) for the general account contract(s) held by or on behalf of any employee benefit plan together with the amount of the reserves and liabilities for the general account contract(s) held by or on behalf of any other employee benefit plans maintained by the same employer (or affiliate thereof as defined in PTE 95-60) or by the same employee organization in the general account do not exceed 10% of the total reserves and liabilities of the general account (exclusive of separate account liabilities) plus surplus as set forth in the NAIC Annual Statement filed with such Purchaser’s state of domicile; or

Each of the Sunnova Parties and the Purchasers agree with respect to any Notes (a) to treat and shall treat the Notes as indebtedness for all tax purposes and (b) to take no action or fail to take any action, which could reasonably be expected to prevent the Notes from being treated as indebtedness for tax purposes unless otherwise required by Applicable Law.

Section 16. Acknowledgement and Consent to Bail-In of EEA Financial Institutions. Notwithstanding anything to the contrary in any Transaction Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any EEA Financial Institution arising under any Transaction Document, to the extent such liability is unsecured, may be subject to the write-down and conversion powers of an EEA Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

(a) the application of any Write-Down and Conversion Powers by an EEA Resolution Authority to any such liabilities arising hereunder which may be payable to it by any party hereto that is an EEA Financial Institution; and

(i) a reduction in full or in part or cancellation of any such liability;

(ii) a conversion of all, or a portion of, such liability into shares or other instruments of ownership in such EEA Financial Institution, its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Transaction Document; or

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to us the enclosed duplicate hereof, whereupon this Agreement will become a binding agreement between the undersigned in accordance with its terms.

of notification of the terms thereof by the Issuer in writing and (b) such Class B Note Purchase Commitment, when exercised, would not result in such Additional Purchaser failing to be able to make the representations set forth in Section 2.06(n)(xi) of the Indenture.

Interest Rate Determination

The interest rate for any Series of Notes will be automatic and determined on the applicable Closing Date as follows:

•

The Class A Notes Interest Rate shall be a percentage (rounded to the nearest hundredths decimal place) equal to (i) ICUR Treasury yield matching the average life of such Series of Class A Notes; plus (ii) the Net Spread at the time such Notes’ interest rate is set.

•

The Class B Notes Interest Rate shall be 6.35%.

For purposes of calculating the Class A Notes Interest Rate, the Net Spread and Spread Premium shall be calculated as follows:

•

Adjusted Spread: shall mean, the Initial Spread plus the Index Spread minus the Initial Index Spread.

•

Index Spread: shall mean, the interpolated yield corresponding to the weighted average life of such Class of such Series of Notes (using BVCSUP10 and BVCSUP30 yields); minus (ii) the ICUR Treasury yield matching the average life of such Series of Notes (to remove the Treasury yield component of the index yield); as of two Business Days Prior to the Funding Date for each Series of Notes

•

Initial Index Spread: shall mean, the interpolated yield corresponding to the weighted average life of such Class of such Series of Notes (using BVCSUP10 and BVCSUP30 yields); minus (ii) the ICUR Treasury yield matching the average life of such Series of Notes (to remove the Treasury yield component of the index yield) as of two Business Days Prior to the Closing Date

•

Initial Spread: shall mean 230 basis points.

•

Net Spread: The Net Spread shall be the greater of (i) 150 bps or (ii) the Adjusted Spread.
