This Indenture (as amended or supplemented from time to time, this "Indenture") is dated as of August 17, 2022 between Sunnova Helios IX Issuer, LLC, a limited liability company organized under the laws of the State of Delaware, as issuer (the "Issuer"), and Wilmington Trust, National Association, a national banking association, not in its individual capacity but solely in its capacity as indenture trustee (together with its successors and assigns in such capacity, the "Indenture Trustee").
Preliminary Statement
Pursuant to this Indenture, there is hereby duly authorized the execution and delivery of three classes of notes designated as the Issuer's 5.00% Solar Loan Backed Notes, Series 2022-B, Class A (the "Class A Notes") and the Issuer’s 6.00% Solar Loan Backed Notes, Series 2022-B, Class B (the "Class B Notes" and together with the Class A Notes, the "Notes").  All covenants and agreements made by the Issuer herein are for the benefit and security of the Holders of the Notes.  The Issuer is entering into this Indenture, and the Indenture Trustee is accepting the trusts created hereby, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged.
Granting Clause
The Issuer hereby Grants to the Indenture Trustee, for the benefit of the Holders of the Notes, as their interests may appear, all of the rights, title, interest and benefits of the Issuer whether now existing or hereafter arising in and to (i) the Initial Solar Loans and any Qualified Substitute Solar Loans, (ii) all Solar Loan Files related to the Solar Loans and any property or assets of the Obligors pledged as collateral under a Solar Loan to secure the repayment of such Solar Loan, including without limitation the related PV System and/or Energy Storage System, each now and hereafter owned, (iii) each Solar Loan Agreement including the right to (a) receive all amounts due under or required to be paid pursuant to such Solar Loan Agreement on and after the related Cut-Off Date (including all interest capitalized and added to the Solar Loan Balance of a Solar Loan on a Section 25D Credit Payment Date, if any), (b) all security interests, liens and assignments securing payment of such Solar Loan Agreement and (c) all books, records and computer tapes relating to such Solar Loan Agreement; (iv) the Issuer's rights in the Electronic Vault, (v) all rights and remedies under the Contribution Agreement, the Performance Guaranty, the Management Agreement, the Servicing Agreement, the Custodial Agreement, any Letter of Credit and all other Transaction Documents, (vi) amounts (including all amounts collected from each Obligor under its Solar Loan Agreement) deposited from time to time into the Lockbox Account, the Collection Account, the Reserve Account, the Equipment Replacement Reserve Account, the Section 25D Interest Account and all amounts deposited from time to time and all Eligible Investments in each such account, (vii) all other assets of the Issuer,  and (viii) the proceeds of any and all of the foregoing including all proceeds of the conversion, voluntary or involuntary, of any of the foregoing into cash or other property (collectively, the "Trust Estate").  Notwithstanding the foregoing, the Trust Estate shall not include (i) any returned items required to be returned to the financial institution maintaining the Lockbox Account, (ii) Obligor Security Deposits on deposit in the Obligor Security Deposit Account nor (iii) amounts received relating to Grid Services. 
Such Grant is made in trust, to secure payments of amounts due with respect to the Notes ratably and without prejudice, priority or distinction between or among the Notes, and to secure (i) the payment of all amounts on the Notes as such amounts become due in accordance with their terms; (ii) the payment of all other sums payable in accordance with

[***] Certain information has been excluded from this exhibit because it is both not material and would likely cause competitive harm to the company if publicly disclosed.






(d)The Initial Outstanding Note Balance of the Class A Notes and the Class B Notes, that may be executed by the Issuer and authenticated and delivered by the Indenture Trustee and Outstanding at any given time under this Indenture is limited to $178,000,000 and $49,700,000, respectively.
(e)Holders of the Notes shall be entitled to payments of interest and principal as provided herein.  Each Class of Notes shall have a final maturity on the Rated Final Maturity.  All Notes of the same Class shall be secured on parity with one another, with no Note of any Class having any priority over any other Note of that same Class.
(f)The Notes that are authenticated and delivered to the Noteholders by the Indenture Trustee upon an Issuer Order on the Closing Date shall be dated as of the Closing Date.  Any Note issued later in exchange for, or in replacement of, any Note issued on the Closing Date shall be dated the date of its authentication.
(g)Each Class of Notes is issuable in minimum denominations of $100,000 and integral multiples of $1,000 in excess thereof; provided that one Note of each Class of Notes may be issued in an amount equal to the minimum initial denomination for such Class of Notes plus any remaining portion of the Initial Outstanding Note Balance of such Class of Notes; provided, further, that the foregoing shall not restrict or prevent the transfer in accordance with the last sentence of Section 2.07 hereof of any Note with a remaining Outstanding Note Balance of less than $100,000.
Section 2.02.    Forms of Notes.  The Notes shall be in substantially the form set forth in Exhibit A-1, Exhibit A-2 and Exhibit A-3, as applicable, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may, consistently herewith, be determined by the Issuer, as evidenced by its execution thereof.
The Definitive Notes shall be typewritten, printed, lithographed or engraved or produced by any combination of these methods, all as determined by the officers executing such Notes, as evidenced by their execution of such Notes.
Each Note shall be dated the date of its authentication.  The terms of the Notes are set forth in Exhibit A-1, Exhibit A-2 and Exhibit A-3 are part of the terms of this Indenture.
(a)Global Notes.  The Notes are being offered and sold by the Issuer to the Initial Purchaser pursuant to the Note Purchase Agreement.
Notes offered and sold within the United States to QIBs in reliance on Rule 144A shall be issued initially in the form of Rule 144A Global Notes, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Indenture Trustee, as custodian for the Securities Depository, and registered in the name of the Securities Depository or a nominee of the Securities Depository, duly executed by the Issuer and authenticated by the Indenture Trustee as hereinafter provided.  The Outstanding Note Balance of the Rule 144A Global Notes may from time to time be increased or decreased by adjustments made on the records of the Indenture Trustee and the Securities Depository or its nominee as hereinafter provided.  The Indenture Trustee shall not be liable for any error or omission by the Securities Depository in making such record adjustments and the records of the Indenture Trustee shall be controlling with regard to outstanding principal amount of Notes hereunder.
    3 
[***] Certain information has been excluded from this exhibit because it is both not material and would likely cause competitive harm to the company if publicly disclosed.






Notes offered and sold outside of the United States in reliance on Regulation S under the Securities Act shall initially be issued in the form of a Regulation S Temporary Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Indenture Trustee, as custodian for the Securities Depository, and registered in the name of the Securities Depository or the nominee of the Securities Depository for the investors' respective accounts at Euroclear Bank S.A./N.V. as operator of the Euroclear System ("Euroclear") or Clearstream Banking société anonyme ("Clearstream"), duly executed by the Issuer and authenticated by the Indenture Trustee as hereinafter provided.  Beneficial interests in the Regulation S Temporary Global Notes may be held only through Euroclear or Clearstream.
Within a reasonable period of time following the expiration of the "40-day distribution compliance period" (as defined in Regulation S), beneficial interests in the Regulation S Temporary Global Note shall be exchanged for beneficial interests in Regulation S Permanent Global Notes upon the receipt by the Indenture Trustee of (i) a written certificate from the Securities Depository, together with copies of certificates from Euroclear and Clearstream, certifying that they have received certification of non-United States beneficial ownership of 100% of the Outstanding Note Balance of the Regulation S Temporary Global Note (except to the extent of any beneficial owners thereof who acquired an interest therein pursuant to another exemption from registration under the Securities Act and who will take delivery of a beneficial ownership interest in a Rule 144A Global Note, all as contemplated by Section 2.08(a)(ii)), and (ii) an Officer's Certificate from the Issuer.  The Regulation S Permanent Global Notes will be deposited with the Indenture Trustee, as custodian, and registered in the name of a nominee of the Securities Depository.  Simultaneously with the authentication of the Regulation S Permanent Global Notes, the Indenture Trustee shall cancel the Regulation S Temporary Global Note.  The Outstanding Note Balance of the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes may from time to time be increased or decreased by adjustments made on the records of the Indenture Trustee and the Securities Depository or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided.  The Indenture Trustee shall incur no liability for any error or omission of the Securities Depository in making such record adjustments and the records of the Indenture Trustee shall be controlling with regard to outstanding principal amount of Regulation S Global Notes hereunder.
Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and prepayments.  Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Indenture Trustee, or by the Note Registrar at the direction of the Indenture Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.08.
The provisions of the "Operating Procedures of the Euroclear System" and "Terms and Conditions Governing Use of Euroclear" and the "Management Regulations" and "Instructions to Participants" of Clearstream shall be applicable to interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes that are held by the members of, or participants in, the Securities Depository ("Agent Members") through Euroclear or Clearstream.
    4 
[***] Certain information has been excluded from this exhibit because it is both not material and would likely cause competitive harm to the company if publicly disclosed.






Except as set forth in Section 2.08, the Global Notes may be transferred, in whole and not in part, only to another nominee of the Securities Depository or to a successor of the Securities Depository or its nominee.
(b)Book-Entry Provisions.  This Section 2.02(b) shall apply only to the Global Notes deposited with or on behalf of the Securities Depository.
The Issuer shall execute and the Indenture Trustee shall, in accordance with this Section 2.02(b), authenticate and deliver one Global Note for each Class of Notes which (i) shall be registered in the name of the Securities Depository or the nominee of the Securities Depository and (ii) shall be delivered by the Indenture Trustee to the Securities Depository or pursuant to the Securities Depository's instructions or held by the Indenture Trustee as custodian for the Securities Depository.
Agent Members shall have no rights either under this Indenture with respect to any Global Note held on their behalf by the Securities Depository or by the Indenture Trustee as custodian for the Securities Depository or under such Global Note, and the Securities Depository may be treated by the Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture Trustee as the absolute owner of such Global Note for all purposes whatsoever.  Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Indenture Trustee or any agent of the Issuer or the Indenture Trustee from giving effect to any written certification, proxy or other authorization furnished by the Securities Depository or impair, as between the Securities Depository and its Agent Members, the operation of customary practices of such Securities Depository governing the exercise of the rights of an owner of a beneficial interest in any Global Note.
The Note Registrar and the Indenture Trustee shall be entitled to treat the Securities Depository for all purposes of this Indenture (including the payment of principal of and interest on the Notes and the giving of instructions or directions hereunder) as the sole Holder of the Notes, and shall have no obligation to the Note Owners.
The rights of Note Owners shall be exercised only through the Securities Depository and shall be limited to those established by law and agreements between such Note Owners and the Securities Depository and/or the Agent Members pursuant to the Note Depository Agreement.  The initial Securities Depository will make book-entry transfers among the Agent Members and receive and transmit payments of principal of and interest on the Notes to such Agent Members with respect to such Global Notes.
Whenever this Indenture requires or permits actions to be taken based upon instructions or directions of Holders of Notes evidencing a specified percentage of the Outstanding amount of the Notes, the Securities Depository shall be deemed to represent such percentage only to the extent that it has received instructions to such effect from Note Owners and/or Agent Members owning or representing, respectively, such required percentage of the beneficial interest in the Notes and has delivered such instructions to the Indenture Trustee.

(c)Definitive Notes.  Except as provided in Sections 2.08 and 2.13, owners of beneficial interests in Global Notes will not be entitled to receive physical delivery of certificated definitive, fully registered Notes (the "Definitive Notes").
Section 2.03.    Payment of Interest.  (a) Noteholders shall, subject to the priorities and conditions set forth in the Priority of Payments, be entitled to receive payments of interest and principal on each Payment Date.  Any payment of interest or principal payable with respect to the Notes on the applicable Payment Date shall be made to the Person in whose name such Note is registered as of the Record Date for such Payment Date in the manner provided in Section 5.09.
(b)On each Payment Date, the Interest Distribution Amount for each Class of Notes will be distributed to the registered Noteholders of the applicable Class of Notes as of the related Record Date to the extent Available Funds are sufficient for such distribution in accordance with the Priority of Payments or the Acceleration Event Priority of Payments, as applicable.  Interest on the Notes with respect to any Payment Date will accrue at the applicable Note Rate based on the Interest Accrual Period.
(c)If the Aggregate Outstanding Note Balance has not been paid in full on or before the Anticipated Repayment Date, additional interest (the "Post-ARD Additional Interest Amounts") will begin to accrue during each Interest Accrual Period thereafter on each outstanding Class of Notes at the related Post-ARD Additional Interest Rate.  The Post-ARD Additional Interest Amounts, if any, for a Class of Notes will only be due and payable (i) after the Aggregate Outstanding Note Balance, any Note Balance Write-Down Amounts and any Deferred Interest amounts have been paid in full or (ii) on the date on which a Voluntary Prepayment of all outstanding Notes in full is being made.  Prior to such time, the Post-ARD Additional Interest Amounts accruing on a Class of Notes will be deferred and added to any Post-ARD Additional Interest Amounts previously deferred and remaining unpaid ("Deferred Post-ARD Additional Interest Amounts"). Deferred Post-ARD Additional Interest Amounts will not bear interest.
Section 2.04.    Payments to Noteholders.  (a) Principal payments and interest on a Class of Notes will be made on each Payment Date to the Noteholders of each Class as of the related Record Date pursuant to the Priority of Payments.  The remaining Outstanding Note Balance of each Class of Notes, if any, shall be payable no later than the Rated Final Maturity.  
(b)All reductions in the principal balance of a Note (or one or more Predecessor Notes) effected by payments of principal made on any Payment Date shall be binding upon all Holders of such Note and of any Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, whether or not such payment is noted on such Note.
(c)The Note Balance Write-Down Amount shall be applied in the following order of priority: (i) to the Class B Notes until the Outstanding Note Balance of the Class B Notes is reduced to zero and (ii) to the Class A Notes until the Outstanding Note Balance of the Class A Notes is reduced to zero.  The application of the Note Balance Write-Down Amount to a Class of Notes will not reduce such Class' entitlement to unpaid principal and interest.

Section 2.05.    Execution, Authentication, Delivery and Dating.  (a) The Notes shall be executed by the Issuer.  The signature of such Authorized Officer on the Notes may be manual or facsimile.  Notes bearing the manual or facsimile signature of any individual who was, at the time of execution thereof, an Authorized Officer of the Issuer shall bind the Issuer, notwithstanding the fact that such individual ceased to hold such office prior to the authentication and delivery of such Notes or did not hold such office at the date of issuance of such Notes.
(b)On the Closing Date, the Issuer shall, and at any time and from time to time after the execution and delivery of this Indenture, the Issuer may deliver Notes executed by the Issuer to the Indenture Trustee for authentication, and the Indenture Trustee, upon receipt of the Notes and of an Issuer Order, shall authenticate and deliver such Notes; provided, however, that the Indenture Trustee shall not authenticate the Notes on the Closing Date unless and until it shall have received the documents listed in Section 2.12. 
(c)Each Note authenticated and delivered by the Indenture Trustee to or upon an Issuer Order on or prior to the Closing Date shall be dated the Closing Date.

Without unreasonable delay, the Issuer will execute and deliver to the Indenture Trustee Definitive Notes (other than in the case of Notes in global form) and thereupon any or all temporary Notes (other than in the case of Notes in global form) may be surrendered in exchange therefor, at the Corporate Trust Office, and the Indenture Trustee shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Definitive Notes.

(ii)The purchaser understands that the Notes and interests therein are being offered in a transaction not involving any public offering in the United States within the meaning of the Securities Act, that the Notes have not been and will not be registered under the Securities Act or any other applicable securities laws and that (A) if in the future it decides to offer, resell, pledge or otherwise transfer any of the Notes or any interests therein, such Notes (or the interests therein) may only be offered, resold, pledged or otherwise transferred in denominations (the "Minimum Denomination") of $100,000 and in each case, in integral multiples of $1,000 in excess thereof, and only (i) in the United States to a person whom the seller reasonably believes is a QIB in a transaction meeting the requirements of Rule 144A (acting for its own account and not for the account of others, or as a fiduciary or agent for other QIBs to whom notice is given that the sale, pledge or transfer is being made in reliance on Rule 144A), (ii) outside the United States in a transaction complying with the provisions of Regulation S under the Securities Act or (iii) pursuant to another exemption from registration under the Securities Act (if available and evidenced by an opinion of counsel acceptable to the Issuer and the Indenture Trustee), in each of cases (i) through (iii) in accordance with any applicable securities laws of any state of the U.S. and any other applicable jurisdiction, and that (B) the purchaser will, and each subsequent holder is required to, notify any subsequent purchaser of such Notes or interests therein from it of the resale restrictions referred to above.

Covenants; Collateral; Representations; Warranties
Section 3.01.    Performance of Obligations.  (a) The Issuer will not take any action or permit any action to be taken by others which would release any Person from any of such Person's covenants or obligations in any Transaction Document or under any instrument or agreement included in the Trust Estate or that would result in the amendment, hypothecation, subordination, termination or discharge of, or impair the validity or effectiveness of, any such instrument or agreement, except as ordered by any bankruptcy or other court or as permitted by, or expressly provided in this Indenture, the Transaction Documents or such other instrument or agreement.
(b)To the extent consistent with the Issuer Operating Agreement, the Issuer may contract with other Persons to assist it in performing its duties hereunder, and any performance of such duties shall be deemed to be action taken by the Issuer.  To the extent that the Issuer contracts with other Persons which include or may include the furnishing of reports, notices or correspondence to the Indenture Trustee, the Issuer shall identify such Persons in a written notice to the Indenture Trustee.
(c)The Issuer shall and shall require that the Depositor, Sunnova Intermediate Holdings and Sunnova ABS Holdings IX characterize (i) each transfer of the Conveyed Property by Sunnova Intermediate Holdings to Sunnova ABS Holdings IX, each transfer of the Conveyed Property by Sunnova ABS Holdings IX to the Depositor and each transfer of the Conveyed Property by the Depositor to the Issuer pursuant to the Contribution Agreement as an absolute transfer for legal purposes, (ii) the Grant of the Trust Estate by the Issuer under this Indenture as a pledge for financial accounting purposes, and (iii) the Notes as indebtedness for U.S. federal income tax purposes (unless otherwise required by Applicable Law) and for financial accounting purposes.

The Issuer will cause Sunnova Energy, Sunnova Intermediate Holdings, Sunnova ABS Holdings IX and the Depositor to file all required Tax Returns and associated forms, reports, schedules and supplements thereto in a manner consistent with such characterizations unless otherwise required by Applicable Law.

(h)If an Event of Default or Servicer Termination Event shall arise from the failure of the Servicer to perform any of its duties or obligations under the Servicing Agreement, the Issuer shall take all reasonable steps available to it to remedy such failure, including appointing a replacement Servicer pursuant to the terms of the Servicing Agreement.
(i)The Issuer, or the Servicer on behalf of the Issuer, will supply to the Indenture Trustee for further distribution to the Noteholders, at the time and in the manner required by applicable Treasury Regulations, and to the extent required by applicable Treasury Regulations, information with respect to any original issue discount accruing on the Notes.

(c)Any money held by the Indenture Trustee in trust for the payment of any amount distributable but unclaimed with respect to any Note shall be held in a non-interest bearing trust account, and if the same remains unclaimed for two years after such amount has become due to such Noteholder, such money shall be discharged from such trust and paid to the Issuer upon an Issuer Order without any further action by any Person; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof (but only to the extent of the amounts so paid to the Issuer), and all liability of the Indenture Trustee with respect to such trust money shall thereupon cease.  The Indenture Trustee may adopt and employ, at the expense of the Issuer, any reasonable means of notification of such payment (including, but not limited to, mailing notice of such payment to Noteholders whose Notes have been called but have not been surrendered for prepayment or whose right to or interest in moneys due and payable but not claimed is determinable from the records of the Indenture Trustee, at the last address of record for each such Noteholder).

Section 5.09.    Note Payments.  (a) The Indenture Trustee shall pay from amounts on deposit in the Collection Account in accordance with the Monthly Servicer Report and the Priority of Payments or the Acceleration Event Priority of Payments, as applicable, to each Noteholder of record as of the related Record Date either (i) by wire transfer, in immediately available funds to the account of such Noteholder at a bank or other entity having appropriate facilities therefor, if such Noteholder shall have provided to the Indenture Trustee appropriate written instructions at least five Business Days prior to the related Payment Date (which instructions may remain in effect for subsequent Payment Dates unless revoked by such Noteholder), or (ii) if not, by check mailed to such Noteholder at the address of such Noteholder appearing in the Note Register, the amounts to be paid to such Noteholder pursuant to such Noteholder's Notes; provided, however, that so long as the Notes are registered in the name of the Securities Depository such payments shall be made to the nominee thereof in immediately available funds.
(b)In the event that any withholding Tax is imposed on the Issuer's payment (or allocations of income) to a Noteholder, such withholding Tax shall reduce the amount otherwise distributable to the Noteholder in accordance with this Indenture.  The Indenture Trustee is hereby authorized and directed to retain from amounts otherwise distributable to the Noteholders sufficient funds for the payment of any withholding Tax that is legally owed by the Issuer as instructed by the Servicer, in writing in a Monthly Servicer Report (but such authorization shall not prevent the Indenture Trustee from contesting at the expense of the applicable Noteholder any such withholding Tax in appropriate Proceedings, and withholding payment of such withholding Tax, if permitted by law, pending the outcome of such Proceedings).  The amount of any withholding Tax imposed with respect to a Noteholder shall be treated as cash distributed to such Noteholder at the time it is withheld by the Issuer or the Indenture Trustee (at the direction of the Servicer or the Issuer) and remitted to the appropriate taxing authority.  If there is a withholding Tax payable with respect to a distribution (such as a distribution to a non-U.S. Noteholder), the Indenture Trustee may in its sole discretion withhold such amounts in accordance with this clause (b).  In the event that a Noteholder wishes to apply for a refund of any such withholding Tax, the Indenture Trustee shall reasonably cooperate with such Noteholder in making such claim so long as such Noteholder agrees to reimburse the Indenture Trustee for any out-of-pocket expenses incurred.

Any such Voluntary Prepayment is required to be made on no less than ten (10) days' prior notice (or such shorter period, but not less than two Business Days, as is necessary to cure an Event of Default) by the Issuer sending the Notice of Prepayment to the Indenture Trustee and the Servicer describing the Issuer's election to prepay the Notes or portion thereof in the form attached hereto as Exhibit C.

The Indenture Trustee will make distributions on the related Voluntary Prepayment Date in accordance with the Priority of Payments (without giving effect to clauses (vii) through (xi) thereof) and solely as specified in the related Voluntary Prepayment Servicer Report and to the extent the Aggregate Outstanding Note Balance is prepaid and all other obligations of the Issuer under the Transaction Documents have been paid, release any remaining assets in the Trust Estate to, or at the direction of, the Issuer.
(d)If a Voluntary Prepayment Date occurs prior to the Make Whole Determination Date for a Class of Notes, the Issuer will be required to pay the Noteholders the applicable Make Whole Amount.  No Make Whole Amount will be due to the Noteholders if a Voluntary Prepayment is made on or after the Make Whole Determination Date. 
(e)If the Issuer elects to rescind the Voluntary Prepayment, it must give written notice to the Indenture Trustee of such determination at least two Business Days prior to the Voluntary Prepayment Date. If a Voluntary Prepayment of the Notes has been rescinded pursuant to this Section 6.01(e), the Indenture Trustee shall provide notice of such rescission to the registered owner of each Note which had been subject to the rescinded redemption at the address shown on the Note Register maintained by the Note Registrar with copies to the Issuer, Sunnova Energy, the Depositor and the Rating Agencies.

Failure to make such Notice of Prepayment available to any Noteholder, or any defect therein, shall not affect the validity of any Proceedings for the prepayment of other Notes.  If a Voluntary Prepayment has been rescinded pursuant to Section 6.01(e), and to the extent the Indenture Trustee had made notice of the Voluntary Prepayment available, the Indenture Trustee shall make available notice of such rescission to the registered owner of each Note which had been subject to the rescinded Voluntary Prepayment with copies to the Issuer, Sunnova Energy, the Servicer and the Rating Agencies.
Any notice made available as provided in this Section shall be conclusively presumed to have been duly given, whether or not the registered owner of such Notes accesses the notice.

Article IX or by law to the Indenture Trustee or to the Noteholders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture Trustee or by the Noteholders, as the case may be.
Section 9.11.    Control by Noteholders.  Other than as set forth herein, the Majority Noteholders of the Controlling Class shall have the right to direct the time, method and place of conducting any Proceeding for any remedy available to the Indenture Trustee or exercising any trust or power conferred on the Indenture Trustee; provided that:
(a)such direction shall not be in conflict with any rule of law or with this Indenture including, without limitation, any provision hereof which expressly provides for approval by a greater percentage of the aggregate principal amount of all Outstanding Notes;
(b)the Indenture Trustee may take any other action deemed proper by the Indenture Trustee which is not inconsistent with such direction; provided, however, that, subject to Section 7.01, the Indenture Trustee need not take any action which a Responsible Officer or Officers of the Indenture Trustee in good faith determines might involve it in liability (unless the Indenture Trustee is furnished with the reasonable indemnity referred to in Section 9.11(c)); and
(c)the Indenture Trustee has been furnished reasonable indemnity against costs, expenses and liabilities which it might incur in connection therewith.
Section 9.12.    Waiver of Certain Events by Less Than All Noteholders. The Super-Majority Noteholders of the Controlling Class may, on behalf of the Holders of all the Notes, waive any past Default, Event of Default, Acceleration Event, Servicer Termination Event, or Manager Termination Event, and its consequences, except:
(a)a Default in the payment of the principal of or interest on any Note, or a Default caused by the Issuer becoming subject to registration as an "investment company" under the 1940 Act, or
(b)with respect to a covenant or provision hereof which under Article X cannot be modified or amended without the consent of the Holder of each Outstanding Note affected.
Upon any such waiver, such Default, Event of Default, Acceleration Event, Servicer Termination Event or Manager Termination Event shall cease to exist, and any Default, Event of Default, Acceleration Event, Servicer Termination or Manager Termination Event or other consequence arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default, Event of Default, Servicer Termination Event or Manager Termination Event or impair any right consequent thereon.
Section 9.13.    Undertaking for Costs.  All parties to this Indenture agree, and each Noteholder and each Note Owner by its acceptance of a Note shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Indenture Trustee for any action taken, suffered or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses 
    71

made by such party litigant; but the provisions of this Section 9.13 shall not apply to any suit instituted by the Indenture Trustee or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or interest on any Note on or after the Rated Final Maturity expressed in such Note.
Section 9.14.    Waiver of Stay or Extension Laws.  The Issuer covenants (to the extent that it may lawfully do so) that it will not, at any time, insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.
Section 9.15.    Sale of Trust Estate.  (a) The power to effect any sale of any portion of the Trust Estate pursuant to this Article IX shall not be exhausted by any one or more sales as to any portion of the Trust Estate remaining unsold, but shall continue unimpaired until the entire Trust Estate securing the Notes shall have been sold or all amounts payable on the Notes and under this Indenture with respect thereto shall have been paid.  The Indenture Trustee, acting on its own or through an agent, may from time to time postpone any sale by public announcement made at the time and place of such sale.
(b)The Indenture Trustee shall not, in any private sale, sell to a third party the Trust Estate, or any portion thereof unless the Super-Majority Noteholders of the Controlling Class direct the Indenture Trustee, in writing, to make such sale or unless either (i) the proceeds of such sale or liquidation are sufficient to discharge in full the amounts then due and unpaid upon the Notes for principal and accrued interest and the fees and all other amounts required to be paid pursuant the Priority of Payments or (ii) the Holders of 100% of the principal amount of each Class of Notes then Outstanding consent thereto.  Notwithstanding the foregoing, prior to the consummation of any sale of the Trust Estate (either private or public), the Indenture Trustee shall first offer the Originator the opportunity to purchase the Trust Estate for a purchase price equal to the greater of (x) the fair market value of the Trust Estate and (y) the aggregate outstanding note balance of the Notes, plus accrued interest thereon and fees owed thereto (such right, the "Right of First Refusal"). If the Originator does not exercise its Right of First Refusal within two Business Days of receipt thereof, then the Indenture Trustee shall sell the Trust Estate as otherwise set forth in this Section 9.15; provided, further, that if the Originator does not exercise its Right of First Refusal and the Indenture Trustee elects to sell the Trust Estate in a private sale to a third party, then prior to the sale thereof, the Indenture Trustee shall offer the Originator the opportunity to purchase the Trust Estate for the purchase price being offered by such third party, and the Originator shall have two Business Days to accept such offer.
(c)The Indenture Trustee or any Noteholder may bid for and acquire any portion of the Trust Estate in connection with a public or private sale thereof, and in lieu of paying cash therefor, any Noteholder may make settlement for the purchase price by crediting against amounts owing on the Notes of such Holder or other amounts owing to such Holder secured by this Indenture, that portion of the net proceeds of such sale to which such Holder would be entitled, after deducting the reasonable costs, charges and expenses incurred by the Indenture Trustee or the Noteholders in connection with such sale.  The Notes need not be produced in order to complete any such sale, or in order for the net proceeds of such sale to be credited against the Notes.  The Indenture Trustee or the Noteholders may hold, lease, 
    72

operate, manage or otherwise deal with any property so acquired in any manner permitted by law.
(d)The Indenture Trustee shall execute and deliver an appropriate instrument of conveyance transferring its interest in any portion of the Trust Estate in connection with a sale thereof.  In addition, the Indenture Trustee is hereby irrevocably appointed the agent and attorney-in-fact of the Issuer to transfer and convey its interest in any portion of the Trust Estate in connection with a sale thereof, pursuant to this Section 9.15, and to take all action necessary to effect such sale.  No purchaser or transferee at such a sale shall be bound to ascertain the Indenture Trustee's authority, inquire into the satisfaction of any conditions precedent or see to the application of any monies.
(e)The method, manner, time, place and terms of any sale of all or any portion of the Trust Estate shall be commercially reasonable.
Section 9.16.    Action on Notes.  The Indenture Trustee's right to seek and recover judgment on the Notes or under this Indenture shall not be affected by the seeking, obtaining or application of any other relief under or with respect to this Indenture.  Neither the Lien of this Indenture nor any rights or remedies of the Indenture Trustee or the Noteholders shall be impaired by the recovery of any judgment by the Indenture Trustee against the Issuer or by the levy of any execution under such judgment upon any portion of the Trust Estate or upon any of the assets of the Issuer.

(b)With the prior written consent of the Majority Noteholders of the Controlling Class, and receipt by the Indenture Trustee of a Tax Opinion, the Issuer and the Indenture Trustee, when authorized by an Issuer Order, at any time and from time to time, may enter into one or more amendments or indentures supplemental hereto, in form satisfactory to the Indenture Trustee for the purpose of modifying, eliminating or adding to the provisions of this Indenture; provided that such supplemental indentures shall not have any of the effects described in paragraphs (i) through (v) of Section 10.02(a).
(c)Promptly after the execution by the Issuer and the Indenture Trustee of any amendment or supplemental indenture pursuant to this Section 10.02, the Indenture Trustee shall make available to the Noteholders and the Rating Agencies a copy of such supplemental indenture.

Miscellaneous
Section 12.01.    Compliance Certificates and Opinions; Furnishing of Information.  Upon any application or request by the Issuer to the Indenture Trustee to take any action under any provision of this Indenture (except with respect to ordinary course actions under this Indenture and except as otherwise specifically provided in this Indenture), the Issuer at the request of the Indenture Trustee shall furnish to the Indenture Trustee a certificate describing that all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel describing that, in the opinion of such counsel, all such conditions precedent, if any, have been complied with, except that in the case of any such application or request as to which the furnishing of certificates and Opinions of Counsel are specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or Opinion of Counsel need be furnished.
Section 12.02.    Form of Documents Delivered to Indenture Trustee.  (a) If several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.
(b)Any certificate or opinion of an Authorized Officer of the Issuer may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by outside counsel, unless such Authorized Officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous.  Any such certificate or opinion or any Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an Authorized Officer of any relevant Person, describing that the information with respect to such factual matters is in the possession of such Person, unless such officer or counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.  Any Opinion of Counsel may be based on the written opinion of other counsel, in which event such Opinion of Counsel shall be accompanied by a copy of such other counsel's opinion and shall include a statement to the effect that such counsel believes that such counsel and the Indenture Trustee may reasonably rely upon the opinion of such other counsel.
(c)Where any Person is required to make, give or execute two or more applications, requests, consents, notices, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

(d)Wherever in this Indenture, in connection with any application or certificate or report to the Indenture Trustee, it is provided that the Issuer, the Servicer or the Manager shall deliver any document as a condition of the granting of such application, or as evidence of the Issuer's, the Servicer's or the Manager's compliance with any term hereof, it is intended that the truth and accuracy, at the time of the granting of such application or at the effective date of such notice or report (as the case may be), of the facts and opinions stated in such document shall in such case be conditions precedent to the right of the Issuer to have such application granted or to the sufficiency of such notice or report.  The foregoing shall not, however, be construed to affect the Indenture Trustee's right to rely upon the truth and accuracy of any statement or opinion contained in any such document as provided in Section 7.01(b)(ii).
(e)Wherever in this Indenture it is provided that the absence of the occurrence and continuation of a Default, an Event of Default, a Servicer Termination Event or a Manager Termination Event is a condition precedent to the taking of any action by the Indenture Trustee at the request or direction of the Issuer, then notwithstanding that the satisfaction of such condition is a condition precedent to the Issuer's or the Indenture Trustee's right to make such request or direction, the Indenture Trustee shall be protected in acting in accordance with such request or direction if a Responsible Officer of the Indenture Trustee does not have actual knowledge of the occurrence and continuation of such Default, Event of Default, Servicer Termination Event or Manager Termination Event.
Section 12.03.    Acts of Noteholders.  (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Noteholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Noteholders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Indenture Trustee, and, where it is hereby expressly required, to the Issuer.  Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Noteholders signing such instrument or instruments.  Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 7.01) conclusive in favor of the Indenture Trustee and the Issuer, if made in the manner provided in this Section 12.03.
(b)The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof.  Whenever such execution is by an officer of a corporation or a member of a limited liability company or a partnership on behalf of such corporation, limited liability company or partnership, such certificate or affidavit shall also constitute sufficient proof of his authority.
(c)The ownership of Notes shall be proved by the Note Register.
(d)Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Notes shall bind the Holder of every Note issued upon the registration or transfer thereof or in exchange therefor or in lieu thereof, with respect to anything done, omitted or suffered to be done by the Indenture Trustee or the Issuer in reliance thereon, whether or not notation of such action is made upon such Notes.

Notices delivered to the Rating Agencies shall be by electronic delivery to the email address set forth above where information is available in electronic format.  In addition, upon the written request of any beneficial owner of a Note, the Indenture Trustee shall provide to such beneficial owner copies of such notices, reports or other information delivered, in one or more of the means requested, by the Indenture Trustee hereunder to other Persons as such beneficial owner may reasonably request.
Section 12.05.    Notices and Reports to Noteholders; Waiver of Notices.  (a) Where this Indenture provides for notice to Noteholders of any event or the mailing of any report to the Noteholders, such notice or report shall be written and shall be sufficiently given (unless otherwise herein expressly provided) if mailed, first-class, postage-prepaid, to each Noteholder affected by such event or to whom such report is required to be mailed or sent via electronic mail, at the address or electronic mail address of such Noteholder as it appears on the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice or the mailing of such report.  In any case where a notice or report to Noteholders is mailed in the manner provided above, neither the failure to mail such notice or report, nor any defect in any notice or report so mailed, to any particular Noteholder shall affect the sufficiency of such notice or report with respect to other Noteholders, and any notice or report which is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided.
(b)Where this Indenture provides for notice in any manner, such notice may be waived in writing by any Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice.  Waivers of notice by Noteholders shall be filed with the Indenture Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.
(c)If, by reason of the suspension of regular mail service as a result of a strike, work stoppage or similar activity, it shall be impractical to mail notice of any event to the Noteholders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving of such notice.
(d)The Indenture Trustee shall promptly upon written request furnish to each Noteholder each Monthly Servicer Report and, unless directed to do so under any other provision of this Indenture or any other Transaction Document (in which case no request shall be necessary), a copy of all reports, financial statements and notices received by the Indenture Trustee pursuant to this Indenture and the other Transaction Documents, but only with the use of a password provided by the Indenture Trustee; provided, however, the Indenture Trustee shall have no obligation to provide such information described in this Section 12.05 until it has received the requisite information from the Issuer or the Servicer.  The Indenture Trustee will make no representation or warranties as to the accuracy or completeness of such documents and will assume no responsibility therefor.  The Indenture Trustee's internet website will initially be located at www.wilmingtontrustconnect.com or at such other address as the Indenture Trustee shall notify the parties to the Indenture from time

to time.  In connection with providing access to the Indenture Trustee's website, the Indenture Trustee may require registration and the acceptance of a disclaimer.  The Indenture Trustee shall not be liable for the dissemination of information in accordance with this Indenture.
Section 12.06.    Rules by Indenture Trustee.  The Indenture Trustee may make reasonable rules for any meeting of Noteholders.
Section 12.07.    Issuer Obligation.  Each of the Indenture Trustee and each Noteholder accepts that the enforcement against the Issuer under this Indenture and under the Notes shall be limited to the assets of the Issuer, whether tangible or intangible, real or person (including the Trust Estate) and the proceeds thereof.  No recourse may be taken, directly or indirectly, against (a) any member, manager, officer, employee, trustee, agent or director of the Issuer or of any predecessor of the Issuer, (b) any member, manager, beneficiary, officer, employee, trustee, agent, director or successor or assign of a holder of a member or limited liability company interest in the Issuer, or (c) any incorporator, subscriber to capital stock, stockholder, officer, director, employee or agent of the Indenture Trustee or any predecessor or successor thereof, with respect to the Issuer's obligations with respect to the Notes or any of the statements, representations, covenants, warranties or obligations of the Issuer under this Indenture or any Note or other writing delivered in connection herewith or therewith.
