Amounts borrowed hereunder and subsequently repaid may not be re-borrowed.

[***] = 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.

2

Section 2.02. Loan Procedures. The Borrower may request the Lender to make the Loan to the Borrower by the delivery to the Agent and the Lender on the proposed borrowing date of a written notice in the form of Exhibit B (a “Borrowing Request”). Such notice shall specify (i) the Initial Outstanding Loan Balance, (ii) the Initial Component 1 Balance, the Initial Component 2 Balance and the Initial DOE Component Balance and (iii) the date of borrowing. Subject to the satisfaction of the conditions precedent set forth in Sections 2.08 and 2.09 hereof, the Lender shall make the Loan in the amount of the Initial Outstanding Loan Balance to the Borrower in the manner set forth in the Borrowing Request.

Section 2.03. Use of Proceeds. Upon receipt by the Agent in the Lender Account from the Lender of the proceeds of the Loan, the Agent shall, based on the Borrowing Request, cause the proceeds of the Loan to be made in accordance with the Borrowing Request.

Section 2.04. Payment of Interest.

(a) The Lender and the Guarantor shall, subject to the priorities and conditions set forth in the Priority of Payments, be entitled to receive payments of interest on each Payment Date.

(b) On each Payment Date, the Interest Distribution Amount for each Component shall be distributed to the extent Borrower Available Funds are sufficient for such distribution in accordance with the Priority of Payments. Interest on each Component of the Loan with respect to any Payment Date shall accrue at the Component 1 Rate, the Component 2 Rate or the DOE Component Rate, as applicable, based on the Interest Accrual Period.

(c) If the Outstanding Component 1 Balance or the Outstanding Component 2 Balance has not been paid in full on or before the then-current Anticipated Repayment Date (if any), additional interest (the “Post-ARD Additional Interest Amounts”) shall begin to accrue during each Interest Accrual Period thereafter on the Outstanding Component 1 Balance or the Outstanding Component 2 Balance, as applicable, at the related Post-ARD Additional Interest Rate. For the avoidance of doubt, (i) if a Permitted Refinancing occurs after the Anticipated Repayment Date for the prior financing of the Loan, Post-ARD Additional Interest Amounts will cease accruing hereunder until the Anticipated Repayment Date for such Permitted Refinancing and (ii) if there is no anticipated repayment date in a Permitted Refinancing, Post-ARD Additional Interest Amounts will cease accruing hereunder on the date such Permitted Refinancing is effected. Post-ARD Additional Interest Amounts, if any, shall only be due and payable (i) after the Outstanding Loan Balance has been paid in full in accordance with the Priority of Payments or (ii) on the date on which a Voluntary Prepayment in full pursuant to Section 6.01(c) hereof is made. Prior to such time, the Post-ARD Additional Interest Amounts accruing on the Outstanding Component 1 Balance and the Outstanding Component 2 Balance, shall 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 shall not bear additional interest on any unpaid amounts after the date such Post-ARD Additional Interest Amounts have initially been accrued.

(d) Interest Distribution Amounts will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

Section 2.05. Payment of Principal. The Lender and the Guarantor shall, to the extent Borrower Available Funds are sufficient for such distribution in accordance with the Priority of Payments, be entitled to receive payments of principal on each Payment Date. The maturity date for this facility is the Maturity Date and notwithstanding any other provision to the contrary, the Outstanding Loan Balance of the Loan and the other Borrower Secured Obligations owing under this Loan Agreement and the other Loan Documents, together with all accrued but unpaid interest thereon, shall be due and payable in full, if not due and payable earlier, on the Maturity Date. At the earlier of (i) the acceleration of the Loan and (ii) the Maturity Date, any Guaranteed Principal Amounts that were deemed paid by the Guarantor pursuant to Section 9.4(b) of the Guarantee Issuance Agreement but were not actually paid by the Guarantor will (a) be reinstated to the Outstanding Component 1 Balance and any accrued and unpaid interest on such deemed payments (as of the date such payments were deemed to be paid) will be due and payable in respect of Component 1 and (b) the Outstanding DOE Component Balance and other Guarantor Reimbursable Amounts will be correspondingly reduced; provided that the foregoing reinstatement of Outstanding Component 1 Balance with any accrued and unpaid interest thereon and the corresponding reduction of the Outstanding DOE Component Balance and other Guarantor Reimbursable Amounts shall not occur if the Guarantor has initiated payment of such amounts to the Lender. To the extent the Lender receives proceeds in respect of the Outstanding Component 1 Balance in connection with a foreclosure on the Collateral while Guarantee Demand Requests for such amounts remain outstanding under the Guarantee Issuance Agreement, the Guarantee Demand Requests for such amounts under the Guarantee Issuance Agreement shall automatically be reduced by the amount of such proceeds. Additionally, to the extent any Guarantee Demand Requests by the Agent have been withdrawn, any payments from the Guarantor received by the Lender in respect of withdrawn Guarantee Demand Requests shall be promptly returned to the Guarantor.

Section 2.06. Borrower Secured Obligations. All other payments with respect to Borrower Secured Obligations shall be made to the extent Borrower Available Funds are sufficient for such distribution in accordance with the Priority of Payments.

Section 2.07. Form of Loan Note. The Loan shall be evidenced by a Loan Note, substantially the form set forth in Exhibit A, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Loan Agreement, 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 Borrower, as evidenced by its execution thereof.

The Agent acknowledges and agrees that (1) each item of property (whether investment property, financial asset, security, instrument or cash) credited to the Accounts shall be treated as a “financial asset” within the meaning of Section 8-102(a)(9) of the New York UCC and (2) notwithstanding anything to the contrary, if at any time the Agent shall receive any order from the Agent (in its capacity as securities intermediary) directing transfer or redemption of any financial asset relating to the Accounts, the Agent shall comply with such entitlement order without further consent by the Borrower, or any other person. In the event of any conflict of any provision of this Section 5.01(g)(ii)(F) with any other provision of this Loan Agreement or any other agreement or document, the provisions of this Section 5.01(g)(ii)(F) shall prevail.

If there is a withholding Tax payable with respect to a distribution, the Agent may in its sole discretion withhold such amounts in accordance with this Section 5.09. In the event that the Lender wishes to apply for a refund of any such withholding Tax, the Agent shall reasonably cooperate with the Lender in making such claim so long as the Lender agrees to reimburse the Agent 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 Borrower sending the Notice of Voluntary Prepayment to the Agent, the Guarantor and the Servicer describing the Borrower’s election to prepay the Loan or portion thereof in the form attached hereto as Exhibit C. The Borrower may not prepay the Loan during the Prepayment Lockout Period.

(b) With respect to any Voluntary Prepayment in part, on or prior to the related Voluntary Prepayment Date, the Borrower shall deposit into the Collection Account, an amount equal to the sum of (i) the amount of outstanding principal of the Loan being prepaid and (ii) all accrued and unpaid interest thereon. Such partial Voluntary Prepayment shall be distributed by the Agent, based on the Monthly Servicer Report, on the related Voluntary Prepayment Date pro rata between (i) Component 1 and the DOE Component and (ii) Component 2. With respect to clause (i) of the immediately preceding sentence, such partial Voluntary Prepayment shall be distributed (A) first, to the Lender Account in respect of the Outstanding Component 1 Balance until the Outstanding Component 1 Balance is reduced to $[***] and (B) second, to the Guarantor in respect of the Outstanding DOE Component Balance until the Outstanding DOE Component Balance is reduced to $[***].

The Agent shall make distributions on the related Voluntary Prepayment Date in accordance with the Priority of Payments (without giving effect to clauses (vi) through (x) thereof) and solely as specified in the related Voluntary Prepayment Servicer Report and to the extent the Outstanding Loan Balance is prepaid and all other obligations of the Borrower under the Loan Documents have been paid, release any remaining assets in the Collateral to, or at the direction of, the Borrower.

(d) If the Borrower elects to rescind the Voluntary Prepayment, it must give written notice to the Agent and the Guarantor of such determination at least two Business Days prior to the Voluntary Prepayment Date. If a Voluntary Prepayment of the Loan has been rescinded pursuant to this Section 6.01(d), the Agent shall provide notice of such rescission to the Lender with copies to the Guarantor, the Borrower, the Capital Markets Issuer, the Indenture Trustee, Sunnova Energy, the Depositor, the Rating Agency and Fitch.

(f) No Voluntary Prepayment in full or in part may be effected unless the Capital Markets Issuer (if any) has deposited into the Lender Account any amounts payable by the Capital Markets Issuer in connection with such prepayment that are not correspondingly payable by the Borrower in respect of the Loan.

Failure to make such Notice of Voluntary Prepayment available to any such Person, or any defect therein, shall not affect the validity of any Proceedings for the prepayment of the Loan. If a Voluntary Prepayment has been rescinded pursuant to Section 6.01(d), and to the extent the Agent had made notice of the Voluntary Prepayment available, the Agent shall make available notice of such rescission to the Lender with copies to the Borrower, the Capital Markets Issuer, the Guarantor, Sunnova Energy, the Servicer and the Rating Agency. Any notice made available as provided in this Section shall be conclusively presumed to have been duly given, whether or not the intended recipient accesses the notice.

In the case of an Event of Default, after the applicable grace period set forth in such subparagraphs, if any, the Agent shall give written notice to the Lender, the Guarantor, the Rating Agency, Fitch, the Manager, the Servicer, the Back-Up Servicer, the Transition Manager and the Borrower that an Event of Default has occurred as of the date of such notice.

Section 9.02. Actions of Agent. If an Event of Default shall have occurred and be continuing hereunder, the Agent shall, at the direction of the Controlling Party, do one of the following:

(a) declare the entire unpaid principal amount of the Loan, all interest accrued and unpaid thereon and all other amounts payable under this Loan Agreement and the other Loan Documents to become immediately due and payable;

(b) either on its own or through an agent, take possession of and sell the Collateral pursuant to Section 9.15, provided, however, that neither the Agent nor any collateral agent may sell or otherwise liquidate the Collateral unless either (i) the proceeds of such sale or liquidation are sufficient to discharge in full the amounts then due and unpaid upon the Loan for principal and accrued interest and the fees and all other amounts required to be paid pursuant to the Priority of Payments, as applicable, or (ii) so long as the Guarantee Issuance Agreement remains in effect and the Guarantor has made all required payments pursuant to the Guarantee Issuance Agreement, the Guarantor consents thereto;

(c) institute Proceedings for collection of amounts due on the Loan or under this Loan Agreement by automatic acceleration or otherwise, or if no such acceleration or collection efforts have been made, or if such acceleration or collection efforts have been made, but have been annulled or rescinded, the Agent may elect to take possession of the Collateral and collect or cause the collection of the proceeds thereof and apply such proceeds in accordance with the applicable provisions of this Loan Agreement;

(d) enforce any judgment obtained and collect any amounts adjudged from the Borrower;

(e) institute any Proceedings for the complete or partial foreclosure of the Lien created by the Agreement with respect to the Collateral; and

Notwithstanding the foregoing, upon the occurrence of an Event of Default of the type described in clause (c) of the definition thereof, the Outstanding Loan Balance, all interest accrued and unpaid thereon and all other amounts payable under the Agreement and the other Loan Documents shall automatically become immediately due and payable.

Section 9.03. Agent May File Proofs of Claim.

[***] = 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.

56

(a) file and prove a claim for the whole amount owing and unpaid with respect to the Loan issued hereunder and file such other papers or documents as may be necessary or advisable in order to have the claims of the Agent (including any claim for the reasonable compensation, expenses and disbursements of the Agent, its agents and counsel) and of the Controlling Party and the Lender allowed in such Insolvency Proceeding; and

(b) collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any receiver, assignee, trustee, liquidator, or sequestrator (or other similar official) in any such Insolvency Proceeding is hereby authorized by the Controlling Party and the Lender to make such payments to the Agent and, in the event that the Agent shall, upon written direction from the Controlling Party, consent to the making of such payments directly to the Controlling Party and the Lender, to pay to the Agent any amount due to it for the reasonable compensation, expenses and disbursements of the Agent, its agents and counsel, and any other amounts due the Agent under Section 7.07.

Nothing herein contained shall be deemed to authorize the Agent to authorize and consent to or accept or adopt on behalf of the Controlling Party and the Lender any plan of reorganization, arrangement, adjustment, or composition affecting the Loan Note or the rights of the Controlling Party and the Lender, or to authorize the Agent to vote with respect to the claim of the Controlling Party and the Lender in any such Insolvency Proceeding.

Section 9.04. Agent May Enforce Claim Without Possession of the Loan Note. All rights of action and claims under this Loan Agreement or the Loan Note may be prosecuted and enforced by the Agent without the possession of the Loan Note or the production thereof in any Proceeding relating thereto, and any such Proceeding instituted by the Agent shall be brought in its own name as trustee for the benefit of the Secured Parties, and any recovery of judgment shall be applied first, to the payment of the reasonable compensation, expenses and disbursements of the Agent, its agents and counsel and any other amounts due the Agent under Section 7.07 (provided that, any indemnification by the Borrower under Section 7.07 shall be paid only in accordance with the Priority of Payments) and second, for the ratable benefit of the Secured Parties for all amounts due to such Secured Parties.

Section 9.07. Unconditional Right of the Lender to Receive Principal and Interest.

Section 9.08. Restoration of Rights and Remedies. If the Agent or the Controlling Party has instituted any Proceeding to enforce any right or remedy under this Loan Agreement and such Proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Agent or to the Controlling Party, then, and in every case, the Borrower, the Agent and the Controlling Party 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 Agent and the Controlling Party shall continue as though no such Proceeding had been instituted.

Section 9.09. Rights and Remedies Cumulative. No right or remedy herein conferred upon or reserved to the Agent or to the Controlling Party 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 Agent or of any Secured Party 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 Agent or any Secured Party may be exercised from time to time, and as often as may be deemed expedient, by the Agent or a Controlling Party, as the case may be.

Section 9.11. Control by the Controlling Party. Other than as set forth herein, the Controlling Party shall have the right to direct the time, method and place of conducting any Proceeding for any remedy available to the Agent or exercising any trust or power conferred on the Agent; provided that:

(a) such direction shall not be in conflict with any rule of law or with this Loan Agreement including;

(b) the Agent may take any other action deemed proper by the Agent which is not inconsistent with such direction; provided, however, that, subject to Section 7.02, the Agent need not take any action which a Responsible Officer of the Agent in good faith determines might involve it in liability (unless the Agent is furnished with the reasonable indemnity referred to in Section 9.11(c)); and

(c) the Agent 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 the Controlling Party. The Controlling Party on behalf of the Secured Parties may waive any past Default, Event of Default, Servicer Termination Event, or Manager Termination Event, and its consequences. Upon any such waiver, such Default, Event of Default, Servicer Termination Event or Manager Termination Event shall cease to exist, and any Default, Event of Default, Servicer Termination Event or Manager Termination Event or other consequence arising therefrom shall be deemed to have been cured for every purpose of this Loan Agreement; 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 Loan Agreement agree that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Loan Agreement, or in any suit against the Agent for any action taken, suffered or omitted by it as the Agent, 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 Agent or to any suit instituted by the Lender or the Guarantor for the enforcement of the payment of the principal of or interest on the Loan Note on or after the Maturity Date expressed in the Loan Note.

Section 9.14. Waiver of Stay or Extension Laws. The Borrower covenants (to the extent that it may lawfully do so) that it shall 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 Loan Agreement; and the Borrower (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Agent, but shall suffer and permit the execution of every such power as though no such law had been enacted.

Section 9.15. Sale of Collateral. (a) The power to effect any sale of any portion of the Collateral pursuant to this Article IX shall not be exhausted by any one or more sales as to any portion of the Collateral remaining unsold, but shall continue unimpaired until the Collateral securing the Loan shall have been sold or all amounts payable on the Loan and under this Loan Agreement with respect thereto shall have been paid. The Agent, 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 Agent shall not, in any private sale, sell to a third party the Collateral, or any portion thereof unless the Controlling Party directs the Agent, 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 Loan for principal and accrued interest and the fees and all other amounts required to be paid pursuant the Priority of Payments or (ii) so long as the Guarantee Issuance Agreement remains in effect and the Guarantor has made all required payments pursuant to the Guarantee Issuance Agreement, the Guarantor consents thereto.

(c) The Agent, the Guarantor, the Lender and the Originator shall have the right to notice of and to bid for and acquire any portion of the Collateral in connection with a public or private sale thereof, and in lieu of paying cash therefor, such Person may make settlement for the purchase price by crediting against amounts owing on the Loan or other amounts owing to such Person secured by this Loan Agreement, that portion of the net proceeds of such sale to which such Person would be entitled, after deducting the reasonable costs, charges and expenses incurred by the Agent, the Guarantor or the Lender in connection with such sale. The Loan Note 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 Loan. The Agent, the Guarantor, the Lender and the Originator may hold, lease, operate, manage or otherwise deal with any property so acquired in any manner permitted by law.

(d) The Agent shall execute and deliver an appropriate instrument of conveyance transferring its interest in any portion of the Collateral in connection with a sale thereof. In addition, the Agent is hereby irrevocably appointed the agent and attorney-in-fact of the Borrower to transfer and convey its interest in any portion of the Collateral 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 Agent’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 Collateral shall be commercially reasonable and conducted in accordance with Applicable Law; provided that if the Agent, the Guarantor, the Lender or the Originator is the highest bidder for the Collateral or any portion thereof, the Agent shall sell such portion of the Collateral to such Person.

(f) In connection with any sale of any portion of the Collateral pursuant to this Article IX, the Guarantor may at its sole discretion (but shall not be required to) if requested by the holders of the ABS Notes corresponding to Component 2, instruct the Agent to transfer to the Lender (for further distribution to such holders) a representative sample of Solar Loans with an aggregate Solar Loan Balance equal to the Initial Component 2 Percentage Interest of the Aggregate Solar Loan Balance in lieu of distributing cash proceeds of such sale to the Lender. The selection of a representative sample pursuant to this Section 9.15(f) shall be conducted by an Independent Accountant.

Section 9.16. Action on the Loan Note.

Upon any application or request by the Borrower to the Agent to take any action under any provision of this Loan Agreement (except with respect to ordinary course actions under this Loan Agreement and except as otherwise specifically provided in this Loan Agreement), the Borrower at the request of the Agent shall furnish to the Agent a certificate describing that all conditions precedent, if any, provided for in this Loan Agreement 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 Loan Agreement 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 the Agent. (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 Borrower 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 Agent may reasonably rely upon the opinion of such other counsel.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Loan Agreement to be given or taken by the Lender may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by the Lender 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 Agent, and, where it is hereby expressly required, to the Borrower. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Lender signing such instrument or instruments.

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) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Controlling Party shall bind the Lender 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 Agent or the Borrower in reliance thereon, whether or not notation of such action is made upon the Loan Note.
