WHEREAS, all conditions necessary to authorize the execution and delivery of this Supplement and to make it a valid and binding obligation of the Co-Issuers and the Guarantors have been done or performed;

NOW, THEREFORE, in consideration of the agreements and obligations set forth herein and for other good and valuable consideration, the sufficiency of which is hereby acknowledged, the Co-Issuers, the Guarantors and the Purchasers agree as follows.

NOW, THEREFORE, in consideration of the mutual agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1. AUTHORIZATION OF NOTES.

Section 1.1 Authorization of Notes. The Co-Issuers hereby authorize the creation of a new Series of Notes to be issued pursuant to and in accordance with the NPPA, as amended and supplemented by this Supplement, which new series of Notes shall be known and designated as “3.90% Series A Senior Secured Notes due January 14, 2027” (the “Series A Notes”, which term shall include any such Notes issued in substitution therefor pursuant to Section 13 of the NPPA). The aggregate principal amount of Series A Notes which shall be issued, executed and delivered on the Closing Date (as defined below) shall be $170,000,000; provided, however, that subject to the Co-Issuers’ compliance with Section 10.6 of the NPPA, the Co-Issuers from time to time, without giving notice to or seeking the consent of the Purchasers or any holder of Series A Notes, may issue, subject to the terms and conditions set forth herein and in the NPPA, additional Series A Notes (the “Additional Series A Notes”) in any amount having the same terms as the Series A Notes in all respects, except for the issue date, the issue price and the initial Payment Date. Any such Additional Series A Notes will constitute “Series A Notes” and “Notes” for all purposes of the NPPA and will (together with all other Series A Notes issued under the NPPA and this Supplement) constitute a single series of Notes under the NPPA.

Section 1.2 Form of Notes; Term of the Notes. (a) The Series A Notes shall be substantially in the form set forth in Annex A hereto. The terms and provisions contained in the Series A Notes will constitute, and are hereby expressly made, a part of this Supplement and the Co-Issuers, the Guarantors, the Purchasers party hereto and any holder of the Series A Notes expressly agree to such terms and provision and to be bound thereby. However, to the extent any provision of the Series A Notes conflicts with the express provisions of this Supplement, the provisions of this Supplement shall govern and be controlling with respect to the Series A Notes.

2

(b) The final maturity date for the Series A Notes is January 14, 2027 (such date, the “Maturity Date”). On February 29, 2020, and on the last day of each calendar month thereafter (each, a “Payment Date”) through and including the Maturity Date, the Co-Issuers shall pay the principal amount of the Series A Notes in accordance with the Amortization Schedule attached as Schedule 8.1 to this Supplement (as such Amortization Schedule may be amended from time to time to reflect reductions in principal payments resulting from prepayments of the Series A Notes pursuant to Section 8 of the NPPA) at par and without payment of the Make-Whole-Amount (each a “Scheduled Payment Amount”).

(c) The Co-Issuers shall pay interest on the Series A Notes (computed on the basis of a three hundred sixty (360)-day year of twelve (12) thirty (30)-day months) (i) on the unpaid principal balance of the Series A Notes at the rate of 3.90% per annum accruing from the most recent date on which interest has been paid or, if no interest has been paid on the Series A Notes, from the original date of issuance, on each Payment Date or until the aggregate principal amount of the Series A Notes shall have been paid, and (ii) to the extent permitted by law, (x) on any overdue payment of interest and (y) during the continuance of an Event of Default, on such unpaid balance and on any overdue payment of any Make-Whole Amount, at a rate per annum equal to 2% over interest rate stated above, payable monthly as aforesaid (or at option of the registered holder thereof, on demand).

(d) The Series A Notes are subject to the payment and prepayment provisions of Section 8 of the NPPA, including, but not limited to (i) optional prepayments by the Co-Issuers with a Make-Whole Amount at any time prior to the last twelve calendar months prior to the Maturity Date pursuant to Section 8.2(a) thereof, (ii) optional prepayment by the Co-Issuers without a Make-Whole Amount at any time during the twelve calendar months prior to the Maturity Date pursuant to Section 8.2(b) of the NPPA and (iii) mandatory prepayments at par pursuant to Section 8.8(f) thereof in a Control Event occurs.

(e) Make-Whole Amount for the Series A Notes.

“Make-Whole Amount” means, with respect to any Series A Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Series A Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“Called Principal” means, with respect to any Series A Note, the principal of such Series A Note that is to be prepaid pursuant to Section 8.2 of the NPPA or has become or is declared to be immediately due and payable pursuant to Section 12.1 of the NPPA, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any Series A Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Series A Notes of such series is payable) equal to the Reinvestment Yield with respect to such Called Principal.

3

“Reinvestment Yield” means, with respect to the Called Principal of any Series A Note, 0.50% over the “Ask Yield(s)” to maturity implied by the yield(s) reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the “Ask Yield(s)” Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any Series A Note, 0.50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Series A Note.

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year comprised of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Series A Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the Series A Notes of such series, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 of the NPPA or Section 12.1 of the NPPA.

4

“Settlement Date” means, with respect to the Called Principal of any Series A Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 of the NPPA or has become or is declared to be immediately due and payable pursuant to Section 12.1 of the NPPA, as the context requires.

(f) The Series A Notes shall be senior unsubordinated obligations of the Co-Issuers, guaranteed, jointly and severally, by each of the Guarantors, ranking equally in right of payment with any other Notes issued under the NPPA and any other senior unsubordinated obligations of the Obligors and shall constitute Secured Obligations secured equally and ratably with the other Secured Obligations by the pledge of and Lien on the Collateral under the Security Documents.

Section 1.3 Notes Entitled to the Benefits of the NPPA and other Transaction Documents; Joinder by new Guarantors and Purchaser.

(a) The Series A Notes are a series of Notes issued under the NPPA and shall be entitled to the benefits of the NPPA, including the guaranty by the Guarantors set forth in Section 22 thereof, and the other Transaction Documents. Each of the Co-Issuers and the Guarantors hereby agree that all of their obligations under the NPPA and the other Transaction Documents with respect to the Notes and to the Purchasers of Notes shall apply to the Series A Notes and to each Purchaser party hereto, respectively.

(b) Any Guarantor that was not party to the NPPA (whether as an original signatory thereto or by subsequently executing a joinder thereto (including by entering into a prior NPPA Series Supplement)) prior to the execution and delivery of this Supplement, hereby agrees that by executing and delivering this Supplement, such Guarantor hereby becomes a party to the NPPA as a “Guarantor”, an “Obligor”, a “Project Company” or a “Project Company Parent”, as the case may be, thereunder and shall be bound by the terms and provisions of the NPPA, including but not limited to the guaranty set forth in Section 22 thereof with respect to the Series A Notes authorized hereby and all other Notes issued under the NPPA prior to or after the date hereof, in the same manner as if such Guarantor was an original signatory to the NPPA and, at all times from and after the date hereof, such Guarantor shall be subject to all of the obligations, and be entitled to the rights and benefits, of a Guarantor, an Obligor and a Project Company as set forth in the NPPA.

(c) Each Purchaser hereto agrees that by executing and delivering this Supplement, such Purchaser hereby becomes a party to the NPPA as a “Purchaser” as of the Closing Date with respect to the Series A Notes only and shall be entitled to the rights and benefits, and be bound by the terms and provisions of the NPPA, including but not limited to the representations and warranties of a Purchaser set forth in Section 6 thereof and the provisions relating to confidentiality set forth in Section 20 thereof, in the same manner as if such Purchaser was an original signatory to the NPPA.

(d) The Series A Notes shall be entitled to the benefits of the Collateral Trust Indenture and Security Agreement, dated as of January 15, 2020 (as amended, restated, supplemented, or otherwise modified from time to time, the “Collateral Trust Indenture”), pursuant to which the Co-Issuers and the other Guarantors, to secure their respective obligations under the Notes, including the Series A Notes, the NPPA and the other Transaction Documents, granted a security interest and mortgage and deed of trust Lien to the Trustee on behalf of the Secured Parties (including the holders of the Series A Notes). Concurrently with the entering into of this Supplement, each Purchaser shall execute and deliver to the Trustee a Joinder to the Collateral

5
