THIS INDENTURE (as amended or supplemented from time to time, this “Indenture”) is dated as of June 5, 2024 between Sunnova Hestia II 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 two classes of notes designated as the Issuer’s 5.63% Solar Loan Backed Notes, Series 2024-GRID1, Class 1-A (the “Class 1-A Notes”) and the Issuer’s 9.50% Solar Loan Backed Notes, Series 2024-GRID1, Class 2-A (the “Class 2-A Notes” and together with the Class 1-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 Guaranteed Loan Lender Membership Interests; (ii) all rights and remedies under the Transaction Documents, (iii) amounts deposited from time to time into the Notes Distribution Account (including all payments in respect of the Guaranteed Loan and payments by the Guarantor under the Guarantee Issuance Agreement), the Class 1-A Notes Interest Reserve Account and the Notes General Reserve Account and all amounts deposited from time to time and all Eligible Investments in the Class 1-A Notes Interest Reserve Account and the Notes General Reserve Account, (iv) all other assets of the Issuer and (v) 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 any Excluded Collateral or any 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 the provisions of this Indenture; and (iii) compliance with the provisions of this Indenture, all as provided in this Indenture.

The Indenture Trustee acknowledges such Grant, accepts the trusts hereunder in accordance with the provisions of this Indenture, and agrees to perform the duties herein required pursuant to the terms and provisions of this Indenture and subject to the conditions hereof.

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

ARTICLE I

DEFINITIONS

Except as otherwise specified or as the context may otherwise require, capitalized terms used in this Indenture shall have the respective meanings given to such terms in the Standard Definitions attached hereto as Annex A, which is hereby incorporated by reference into this Indenture as if set forth fully in this Indenture. The rules of construction set forth in Annex A shall apply to this Indenture and are hereby incorporated by reference into this Indenture as if set forth fully in this Indenture.

ARTICLE II

THE NOTES; RECONVEYANCE

Section 2.01. General. (a) The Notes shall be designated as the “Sunnova Hestia II Issuer, LLC, 5.63% Solar Loan Backed Notes, Series 2024-GRID1, Class 1-A” and the “Sunnova Hestia II Issuer, LLC, 9.50% Solar Loan Backed Notes, Series 2024-GRID1, Class 2-A”.

(b) All payments of principal and interest with respect to the Notes shall be made only from the Trust Estate on the terms and conditions specified herein. Each Noteholder and each Note Owner, by its acceptance of a Note, agrees that it will have recourse solely against such Trust Estate and the Guaranteed Loan Lender Collateral.

(c) Except as otherwise provided herein, all Notes shall be substantially identical in all respects. Except as specifically provided herein, all Notes issued, authenticated and delivered under this Indenture shall be in all respects equally and ratably entitled to the benefits hereof without preference, priority or distinction on account of the actual time or times of authentication and delivery, all in accordance with the terms and provisions of this Indenture.

(d) The Initial Outstanding Note Balance of the Class 1-A Notes and the Class 2-A 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 $152,010,000 and $16,890,000, 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.

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

(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 the applicable Minimum Denomination 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 applicable Minimum Denomination 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 the applicable Minimum Denomination.

Section 2.02. Forms of Notes. The Notes shall be in substantially the form set forth in Exhibit A-1 and Exhibit A-2, 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 and Exhibit A-2 and are part of the terms of this Indenture.

(a) Global Notes. The Underwritten Notes are being offered and sold by the Issuer to the Initial Purchasers pursuant to the Note Purchase Agreement and the Placed Notes are being sold directly by the Issuer to certain institutional accredited investors (within the meaning of Rule 501(a)(1),(2),(3),(7) or (9) of the Securities Act) pursuant to the Placed Notes Purchase Agreement.

The Underwritten 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 and the Placed Notes 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.

[***] = Certain information has been excluded from this exhibit because it is both not material and would likely cause 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.

[***] = Certain information has been excluded from this exhibit because it is both not material and would likely cause 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.

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

(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, as set forth in the Issuer Pass-Through Distributions, 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 Notes 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 and such purpose in accordance with the Issuer Pass-Through Distributions. 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 “Notes Post-ARD Additional Interest Amounts”) will begin to accrue during each Interest Accrual Period thereafter on each outstanding Class of Notes at the related Notes Post-ARD Additional Interest Rate. The Notes 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 has been paid in full or (ii) on the date on which an Issuer Voluntary Prepayment of the Aggregate Outstanding Note Balance of the Notes is being made. Prior to such time, the Notes Post-ARD Additional Interest Amounts accruing on a Class of Notes will be deferred and added to any Notes Post-ARD Additional Interest Amounts previously deferred and remaining unpaid (“Deferred Notes Post-ARD Additional Interest Amounts”). Deferred Notes 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 Issuer Pass-Through Distributions. 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.

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.

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

(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. All other Notes that are authenticated after the Closing Date for any other purpose under this Indenture shall be dated the date of their authentication.

(d) Notes issued upon transfer, exchange or replacement of other Notes shall be issued in authorized denominations reflecting the Outstanding Note Balance so transferred, exchanged or replaced, but shall represent only the Outstanding Note Balance so transferred, exchanged or replaced. In the event that any Note is divided into more than one Note in accordance with this Article II, such Outstanding Note Balance shall be divided among the Notes delivered in exchange therefor.

(e) No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication, substantially in the form provided for herein, executed by the Indenture Trustee by the manual signature of a Responsible Officer of the Indenture Trustee, and such executed certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered.

Section 2.06. Temporary Notes. Except for the Notes maintained in book-entry form, temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Definitive Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Issuer. Every such temporary Note shall be executed by the Issuer and authenticated by the Indenture Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the Definitive Notes. 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. Such exchange shall be made by the Issuer at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Definitive Notes authenticated and delivered hereunder.

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

Section 2.07. Registration, Registration of Transfer and Exchange. (a) The Indenture Trustee (in such capacity, the “Note Registrar”) shall cause to be kept at its Corporate Trust Office a register (the “Note Register”), in which, subject to such reasonable regulations as it may prescribe, the Note Registrar shall provide for the registration of the Notes and the registration of transfers of such Notes. The Notes are intended to be obligations in registered form for purposes of Section 163(f), Section 871(h)(2) and Section 881(c)(2) of the Code.

(b) Each Person who has or who acquires any Ownership Interest in a Note shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the provisions of this Section 2.07 and Section 2.08.

of such flow-through entity in any Class 2-A Note, other interest (direct or indirect) in the Issuer, or any interest created under this Indenture and (2) it is not and will not be a principal purpose of the arrangement involving the flow-through entity’s beneficial interest in any Class 2-A Note to permit any entity to satisfy the 100-partner limitation of Section 1.7704-1(h)(1)(ii) of the Treasury Regulations necessary for such entity not to be classified as a publicly traded partnership for U.S. federal income tax purposes.

Section 2.15. Recharacterized Notes. Notwithstanding anything to the contrary herein, if (1) any taxing authority asserts that any of the Notes are not properly classifiable as indebtedness for income Tax purposes (“Recharacterized Notes”) and (2) either (A) the Issuer determines that it will not challenge the assertion of such taxing authority or (B) any such challenge is unsuccessful, the Issuer and the Noteholders agree that (i) the Holders of the Recharacterized Notes shall be treated for all income Tax purposes as partners of a partnership from the issuance of the Notes, (ii) payments on the Recharacterized Notes shall be treated as “guaranteed payments” under Section 707 of the Code and (iii) all items of taxable income, gain, loss, deduction, or credit of the partnership for such taxable year and any separately allocable items thereof shall be allocated to the member(s) of the Issuer under the Issuer Operating Agreement. In the event it is determined that payments on the Recharacterized Notes are not properly treated as “guaranteed payments” in accordance with clause (ii) of the preceding sentence, then, prior to the application of clause (iii) of the preceding sentence, taxable income or items of gross income of the partnership for each taxable year of the partnership, in an amount corresponding to the aggregate distributions of interest to the Holders of Recharacterized Notes made pursuant to the terms of this Indenture during such taxable year, shall be specially allocated to the Holders of the Recharacterized Notes pro rata in the proportion that the amount of distributions received by each such Holder during such taxable year bears to the aggregate amount of distributions of interest received by all Holders of Recharacterized Notes pursuant to the terms of this Indenture during such taxable year; provided that to the extent that distributions of interest to the Holders of Recharacterized Notes pursuant to the terms of this Indenture during any taxable year exceed the taxable income or gross income of the partnership during such taxable year, the amount of such excess shall be specially allocated to such Holders in accordance with the preceding provisions of this Section 2.15 in any subsequent taxable year or years of the partnership to the extent of the taxable income or gross income of the partnership in such subsequent taxable year or years. The foregoing provisions of this Section 2.15 are intended to comply with the requirements of Section 704 of the Code and the Treasury Regulations promulgated thereunder, including, without limitation, the “qualified income offset” requirement of Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and the partner minimum gain chargeback provisions of Treasury Regulation Section 1.704-2, and shall be interpreted and applied in a manner consistent therewith.

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 the Guaranteed Loan Lender Collateral 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, the Guaranteed Loan 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 Hestia Holdings characterize (i) the Grant of the Trust Estate by the Issuer under this Indenture and the Grant of the Guaranteed Loan Lender Collateral under the Guaranteed Loan Lender Security Agreement, in each case, as a pledge for financial accounting purposes, and (ii) the Notes as indebtedness for U.S. federal income tax purposes (unless otherwise required by Applicable Law) and for financial accounting purposes. In this regard, the financial statements of SEI and its consolidated subsidiaries will show the Solar Loans as owned by the consolidated group and the Notes as indebtedness of the consolidated group (and will contain appropriate footnotes stating that the assets of the Issuer, the Guaranteed Loan Lender and the Guaranteed Loan Borrower will not be available to creditors of SEI, Sunnova Energy, Sunnova Intermediate Holdings, Sunnova Hestia Holdings or the Depositor or any other Person), and the U.S. federal income Tax Returns of SEI and its consolidated subsidiaries that are regarded entities for U.S. federal income tax purposes will indicate that the Notes are indebtedness unless otherwise required by Applicable Law. The Issuer will cause Sunnova Energy, Sunnova Intermediate Holdings, Sunnova Hestia Holdings 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.

(d) The Issuer covenants to pay, or cause to be paid, all Taxes or other similar charges levied by any governmental authority with regard to the Trust Estate, except to the extent that the validity or amount of such Taxes is contested in good faith, via appropriate Proceedings and with adequate reserves established and maintained therefor in accordance with GAAP.

(e) The Issuer hereby assumes liability for all liabilities associated with the Trust Estate or created under this Indenture, including but not limited to any obligation arising from the breach or inaccuracy of any representation, warranty or covenant of the Issuer set forth herein except as provided in the Transaction Documents. Notwithstanding the foregoing, the Issuer has and shall have no liability with respect to the payment of principal and interest on the Notes, except as otherwise provided in this Indenture.

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

(f) The Issuer will perform and observe all of its obligations and agreements contained in this Indenture, the Transaction Documents and in the instruments and agreements included in the Trust Estate, including, but not limited to, preparing (or causing to be prepared) and filing (or causing to be filed) all UCC financing statements and continuation statements required to be filed by the terms of this Indenture and the other Transaction Documents in accordance with and within the time periods provided for herein and therein. Except as otherwise expressly provided therein, the Issuer shall not waive, amend, modify, supplement or terminate any Transaction Document or any provision thereof without the consent of the Indenture Trustee (acting at the direction of the Majority Noteholders).

(g) [Reserved].

(h) If an Event of Default 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.

(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.

Section 3.02. Negative Covenants. In addition to the restrictions and prohibitions set forth in Sections 3.04 and 3.10 and elsewhere herein, the Issuer will not:

(d) take any action or fail to take any action which action or failure to act may cause the Issuer to become classified as an association, a publicly traded partnership or a taxable mortgage pool that is taxable as a corporation for U.S. federal income tax purposes; or

(e) act in violation of its organization documents.

Section 3.03. Money for Note Payments. (a) All payments with respect to any Notes which are to be made from amounts withdrawn from the Notes Distribution Account pursuant to the Issuer Pass-Through Distributions shall be made on behalf of the Issuer by the Indenture Trustee, and no amounts so withdrawn from an Account for payments with respect to the Notes shall be paid over to the Issuer under any circumstances except as provided in this Section 3.03 and Article V.

(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 3.04. Restriction of Issuer Activities. Until the date that is 365 days after the Termination Date, the Issuer will not on or after the date of execution of this Indenture:

(a) engage in any business or investment activities other than those necessary for, incident to, connected with or arising out of, owning and Granting the Trust Estate to the Indenture Trustee for the benefit of the Noteholders, or contemplated hereby, in the Transaction Documents, the Guaranteed Loan Documents and the Issuer Operating Agreement;

(g) permit the validity or effectiveness of this Indenture to be impaired, or permit the Lien in favor of the Indenture Trustee created by this Indenture or the Guaranteed Loan Lender Security Agreement to be amended, hypothecated, subordinated, terminated or discharged, or permit any Person to be released from any covenants or obligations with respect to the Notes under this Indenture except as may be expressly permitted hereby;

(h) permit the Lien of this Indenture or the Guaranteed Loan Lender Security Agreement not to constitute a valid perfected first priority (other than with respect to a Permitted Lien) Lien on the Trust Estate or the Guaranteed Loan Lender Collateral; or

(i) dissolve, liquidate, merge or consolidate with any other Person, other than in compliance with Section 3.10 if any Notes are Outstanding.

Section 3.05. Protection of Trust Estate. (a) The Issuer intends the Lien Granted pursuant to this Indenture in favor of the Indenture Trustee for the benefit of the Noteholders to be prior to all other Liens in respect of the Trust Estate, subject to Permitted Liens, and the Issuer shall take all actions necessary to obtain and maintain, in favor of the Indenture Trustee and the Noteholders, a first priority, perfected Lien on the Trust Estate, subject to Permitted Liens. The Issuer shall cause the Guaranteed Loan Lender to take all actions necessary to obtain and maintain, in favor of the Issuer, a first priority, perfected Lien on the Guaranteed Loan Collateral, subject to Permitted Liens.

(i) provide (or cause to be provided) further assurance with respect to such Grant and/or Grant more effectively all or any portion of the Trust Estate and the Guaranteed Loan Lender Collateral;

The Indenture Trustee, as secured party of record, hereby authorizes the Issuer and its designees to file amendments to financing statements (other than any amendment terminating a financing statement or reducing the collateral covered thereby) and continuation statements necessary or advisable to accomplish the foregoing. The Issuer shall deliver or cause to be delivered to the Indenture Trustee file-stamped copies of, or filing receipts for, any document recorded, registered or filed as provided above, as soon as available following such recording, registration or filing.

Each Noteholder and Note Owner shall update or replace its previously provided Noteholder Tax Identification Information and Noteholder FATCA Information promptly if requested by the Indenture Trustee; provided that nothing herein shall require the Indenture Trustee to make such request. In addition, each Noteholder and each Note Owner will be deemed to agree that the Indenture Trustee has the right to withhold from any amount of interest or other amounts (without any corresponding gross-up) payable to a Noteholder or Note Owner that fails to comply with the foregoing requirements. The Issuer hereby covenants with the Indenture Trustee that the Issuer will cooperate with the Indenture Trustee in obtaining sufficient information so as to enable the Indenture Trustee to (i) determine whether or not the Indenture Trustee is obliged to make any withholding, including FATCA Withholding Tax, in respect of any payments with respect to a Note and (ii) to effectuate any such withholding.

The Indenture Trustee, upon reasonable written request, shall furnish the Issuer with all such information in the possession of the Indenture Trustee as may be reasonably required in connection with the preparation of any Tax Return of the Issuer.

Section 5.11. Reports by Indenture Trustee. Within five Business Days after the end of each calendar month, the Indenture Trustee shall provide or make available electronically (or upon written request, by first class mail or email) to the Servicer a written report (electronic means shall be sufficient) setting forth the amounts in the Notes Distribution Account, the Class 1-A Notes Interest Reserve Account and the Notes General Reserve Account and the identity of the investments included therein, as applicable.

Section 9.03. Indenture Trustee May File Proofs of Claim. In case of the pendency of any Insolvency Event relative to the Issuer or any other obligor upon the Notes or the property of the Issuer or of such other obligor or their creditors, the Indenture Trustee (irrespective of whether the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Indenture Trustee shall have made any demand on the Issuer for the payment of overdue principal or any interest or other amounts) shall, at the written direction of the Majority Noteholders, by intervention in such Insolvency Event or otherwise,

Nothing herein contained shall be deemed to authorize the Indenture Trustee to authorize and consent to or accept or adopt on behalf of any Noteholder any plan of reorganization, arrangement, adjustment, or composition affecting any of the Notes or the rights of any Noteholder thereof, or to authorize the Indenture Trustee to vote with respect to the claim of any Noteholder in any such Insolvency Event.

Section 9.04. Indenture Trustee May Enforce Claim Without Possession of Notes.

Section 9.05. Knowledge of Indenture Trustee. Any references herein to the knowledge of the Indenture Trustee shall mean and refer to actual knowledge of a Responsible Officer of the Indenture Trustee.

Section 9.06. Limitation on Suits. No Holder of any Note shall have any right to institute any Proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder unless:

it being understood and intended that no one or more Holders of Notes shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders of Notes, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided.

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

Section 9.07. Unconditional Right of Noteholders to Receive Principal and Interest. The Holders of the Notes shall have the right, which is absolute and unconditional, subject to the express terms of this Indenture, to receive payment of principal and interest on such Notes, subject to the respective relative priorities provided for in this Indenture, as such principal and interest becomes due and payable from the Trust Estate and the Guaranteed Loan Lender Collateral and, subject to Section 9.06, to institute Proceedings for the enforcement of any such payment, and such right shall not be impaired except as expressly permitted herein without the consent of such Holders.

Section 9.08. Restoration of Rights and Remedies. If the Indenture Trustee or any Noteholder has instituted any Proceeding to enforce any right or remedy under this Indenture and such Proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Indenture Trustee or to such Noteholder, then, and in every case, the Issuer, the Indenture Trustee and the Noteholders shall, subject to any determination in such Proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Indenture Trustee and the Noteholders shall continue as though no such Proceeding had been instituted.

Section 9.09. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.09, no right or remedy herein conferred upon or reserved to the Indenture Trustee or to the Noteholders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 9.10. Delay or Omission; Not Waiver. No delay or omission of the Indenture Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein. Every right and remedy given by this 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 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

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

(c) the Indenture Trustee has been furnished reasonable indemnity against costs, expenses and liabilities which it might incur in connection therewith.

(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 or Servicer Termination Event shall cease to exist, and any Default, Event of Default or Servicer 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 or Servicer 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 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.

(a) The power to effect any sale of any portion of the Trust Estate pursuant to this Article IX and the Guaranteed Loan Lender Collateral pursuant to the Guaranteed Loan Lender Security Agreement shall not be exhausted by any one or more sales as to any portion of the Trust Estate and the Guaranteed Loan Lender Collateral remaining unsold, but shall continue unimpaired until the entire Trust Estate and entire Guaranteed Loan Lender Collateral 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 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 Issuer Pass-Through Distributions or (ii) other than with respect to an Event of Default described in Section 9.01(b), the Holders of 100% of the Aggregate Outstanding Note Balance consent thereto.

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, 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 and the Guaranteed Loan Lender Collateral in connection with a sale thereof.

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.

Section 9.17. Application of Proceeds Upon Foreclosure. Proceeds received by the Indenture Trustee in connection with a foreclosure of the Trust Estate and/or the Guaranteed Loan Lender Collateral shall be distributed first, to the payment of the reasonable compensation, expenses and disbursements of the Indenture Trustee, its agents and counsel and any other amounts due the Indenture Trustee under Section 7.07 and second, to the Class 1-A Noteholders and the Class 2-A Noteholders as follows: (i) with respect to accrued and unpaid Notes Interest Distribution Amounts, on a pro rata basis (based on amounts due) and (ii) with respect to Outstanding Note Balances of the Notes, on a pro rata basis (based on the Initial Percentage Interest Distribution Methodology).

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.

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

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 or the Servicer shall deliver any document as a condition of the granting of such application, or as evidence of the Issuer’s or the Servicer’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 or Servicer 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, an Event of Default or Servicer Termination Event.
