The Loan shall be comprised of Component 1, Component 2 and the DOE Component.

[***] = 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 2.02. 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.

[***] = 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.

(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 parties hereto agree that each Account shall be governed by the laws of the State of New York, and regardless of any provision in any other agreement, the “securities intermediary’s jurisdiction” (within the meaning of Section 8-110 of the New York UCC) shall be the State of New York. 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.

Section 5.09. Tax Withholding. In the event that any withholding Tax is imposed on the Borrower’s payment (or allocations of income) to the Lender, such withholding Tax shall reduce the amount otherwise distributable to the Lender in accordance with this Loan Agreement. The Agent is hereby authorized and directed to retain from amounts otherwise distributable to the Lender sufficient funds for the payment of any withholding Tax that is legally owed by the Borrower as instructed by the Servicer, in writing in a Monthly Servicer Report (but such authorization shall not prevent the Agent from contesting at the expense of the Lender 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 the Lender shall be treated as cash distributed to the Lender at the time it is withheld by the Borrower or the Agent (at the direction of the Servicer or the Borrower) and remitted to the appropriate taxing authority. 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.

The Lender by its acceptance of a Loan Note or an interest in a Loan Note, will be deemed to have agreed to provide the Agent or the Borrower, upon request, with the Lender Tax Identification Information, and such other information as the Agent or Borrower may reasonably request. The Lender shall update or replace its previously provided Lender Tax Identification Information promptly if requested by the Agent or Borrower; provided that nothing herein shall require the Agent or Borrower to make such request.

Section 5.10. Statements to Lender; Tax Returns. Within the time period required by Applicable Law after the end of each calendar year, the Borrower shall cause the Agent to furnish to the Lender the information required by the Code, if any, to enable the Lender to prepare its U.S. federal and state income Tax Returns. The obligation of the Agent set forth in this Section 5.10 shall be deemed to have been satisfied to the extent that information shall be provided by the Agent, in the form of Form 1099 or other comparable form, pursuant to any requirements of the Code. The Borrower shall cause Sunnova Management, at Sunnova Management’s expense, to cause a firm of Independent Accountants to prepare any Tax Returns required to be filed by the Borrower. The Agent, upon reasonable written request, shall furnish the Borrower with all such information in the possession of the Agent as may be reasonably required in connection with the preparation of any Tax Return of the Borrower.

Section 5.11. Reports by Agent. Within five Business Days after the end of each Collection Period, the Agent shall provide or make available electronically (or upon written request, by first class mail or email) to the Servicer and the Guarantor a written report (electronic means shall be sufficient) setting forth the amounts in the Collection Account, the Reserve Account, the Section 25D Interest Account and the Equipment Replacement Reserve Account and the identity of the investments included therein, as applicable. Without limiting the generality of the foregoing, the Agent shall, upon the written request of the Servicer or the Guarantor, promptly transmit or make available electronically to the Servicer and the Guarantor (or its or their duly authorized representatives or agents, as the case may be), copies of all accountings of, and information with respect to, the Collection Account, the Reserve Account, the Section 25D Interest Account and the Equipment Replacement Reserve Account, investments thereof, as applicable, and payments thereto and therefrom.

Section 5.13. [Reserved].

Section 5.14. The Guarantee Issuance Agreement. Subject to any automatic adjustments to Guarantee Demand Requests made pursuant to Section 2.05, the following shall apply to the Guarantee Issuance Agreement:

(a) Interest Demands. If Borrower Available Funds for any Payment Date and the Maturity Date are insufficient to pay Interest Distribution Amounts that are due and payable on such Payment Date in respect of Component 1 or Component 2 (after giving effect to any amounts transferred from the Reserve Account to the Collection Account), the Agent shall prior to 12:00 p.m. (New York City time) on the third Business Day prior to such Payment Date, issue a Guarantee Demand Request, as provided by the Borrower (or the Servicer on behalf of the Borrower), to the Guarantor pursuant to the procedures set forth in Sections 9.1 and 9.2 of the Guarantee Issuance Agreement in an amount equal to the Guaranteed Amounts entitled to be demanded thereunder as a result of such insufficiency. Such demands will request that Guaranteed Amounts be remitted to the Guarantor Payment Account for the benefit of the Lender. To the extent the Agent receives the proceeds of such request from the Guarantor, the Agent shall remit such amounts directly to the Guarantor Payment Account.

(b) Component 1 Parity Principal Payment Demands. If, after giving effect to the application of Borrower Available Funds for any Payment Date, the Component 1 Parity Ratio is greater than [***]%, the Agent shall, prior to 12:00 p.m. (New York City time) on the third Business Day prior to such Payment Date, issue a Guarantee Demand Request, as provided by the Borrower (or the Servicer on behalf of the Borrower), to the Guarantor pursuant to the procedures set forth in Sections 9.1 and 9.2 of the Guarantee Issuance Agreement in an amount equal to the Component 1 Parity Principal Payment due thereunder. Such demands will request that Guaranteed Amounts be remitted to the Guarantor Payment Account for the benefit of the Lender. To the extent the Agent receives the proceeds of such request to the Guarantor, the Agent shall remit such amounts directly to the Guarantor Payment Account.

(c) Final Drawing. If, on the Maturity Date or after an acceleration of the Loan, the Outstanding Component 1 Balance is greater than $[***], the Agent shall, no later than 12:00 p.m. (New York City time) on the third Business Day prior to such Payment Date, issue a Guarantee Demand Request, as provided by the Borrower (or the Servicer on behalf of the Borrower), to the Guarantor under Sections 9.1 and 9.2 of the Guarantee Issuance Agreement in an amount equal to the unpaid balance of thereof. Such demands will request that Guaranteed Amounts be remitted to the Guarantor Payment Account for the benefit of the Lender. To the extent the Agent receives the proceeds of such request to the Guarantor, the Agent shall remit such amounts directly to the Guarantor Payment Account.

37

[***] = 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.

(d) Discharge of Borrower Obligations. All amounts received in the Guarantor Payment Account pursuant to this Section 5.14 shall be deemed to have discharged the Borrower’s obligations to the Lender pro tanto dollar for dollar to the extent such amounts were so paid into the Guarantor Payment Account.

(e) Application of Guaranteed Interest Amounts Deemed Paid. Guaranteed Interest Amounts deemed to be paid by the Guarantor on any Payment Date will be applied in the following order of priority: (i) first, in satisfaction of any Borrower shortfalls in the Interest Distribution Amount with respect to Component 1 on such Payment Date (such amount in this clause (i), “Guaranteed Interest Amounts (Component 1)”) and (ii) second, any remaining amounts (the “Guaranteed Excess Interest Amounts”) as a pro rata payment of principal on Component 1 and Component 2 (based on the Initial Percentage Interest Distribution Methodology) on such Payment Date, in each case after giving effect to the Priority of Payments.

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.

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.

(e) No Voluntary Prepayment in full may be effected hereunder unless the Capital Markets Issuer (if any) has simultaneously exercised a voluntary prepayment under the related Indenture.

(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.

Section 6.02. Notice of Voluntary Prepayment. Any Notice of Voluntary Prepayment received by the Agent from the Borrower shall be made available by the Agent not less than ten (10) days (or such shorter period in the case of an actual or potential Event of Default) and not more than thirty days prior to the date fixed for prepayment to the Lender with copies to the Borrower, the Capital Markets Issuer, the Guarantor, Sunnova Energy, the Servicer and the Rating Agency. 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.

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.

(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.

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

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.

(d) Wherever in this Loan Agreement, in connection with any application or certificate or report to the Agent, it is provided that the Borrower, the Servicer or the Manager shall deliver any document as a condition of the granting of such application, or as evidence of the Borrower’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 Borrower to have such application granted or to the sufficiency of such notice or report. The foregoing shall not, however, be construed to affect the Agent’s right to rely upon the truth and accuracy of any statement or opinion contained in any such document as provided in Section 7.02(b)(ii).

(e) Wherever in this Loan Agreement 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 Agent at the request or direction of the Borrower, then notwithstanding that the satisfaction of such condition is a condition precedent to the Borrower’s or the Agent’s right to make such request or direction, the Agent shall be protected in acting in accordance with such request or direction if a Responsible Officer of the Agent 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 the Lender.

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. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Loan Agreement and (subject to Section 7.02) conclusive in favor of the Agent and the Borrower, if made in the manner provided in this Section 12.03.

In any case where a notice or report to the Lender or Guarantor 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, shall affect the sufficiency of such notice or report with respect to the Lender or Guarantor, 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 Loan Agreement 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.
