EIGHTH AMENDMENT TO CREDIT AND GUARANTY AGREEMENT

THIS EIGHTH AMENDMENT TO CREDIT AND GUARANTY AGREEMENT (this “Amendment”) is dated as of September 9, 2016 and is entered into by and among TERRAFORM POWER OPERATING, LLC, a Delaware limited liability company (“Borrower’’), the other Credit Parties party hereto, BARCLAYS BANK PLC (“Barclays”), as a Lender and as Administrative Agent (“Administrative Agent”) and the other Lenders party hereto, and is made with reference to that certain CREDIT AND GUARANTY AGREEMENT dated as of January 28, 2015 (as amended through the date hereof, the “Credit Agreement”) by and among Borrower, TERRAFORM POWER, LLC, a Delaware limited liability company, the subsidiaries of Borrower named therein, the Lenders, the Administrative Agent, Collateral Agent and the other Agents named therein. Capitalized terms used herein without definition shall have the same meanings herein as set forth in the Credit Agreement after giving effect to this Amendment.

WHEREAS, if the interest rate payable with respect to the Senior Notes is materially increased in connection with any Senior Notes Waiver, Section 5.19 of the Credit Agreement requires the Borrower and the other Credit Parties to offer to enter into an amendment to the Credit Agreement to increase the Applicable Margin at all leverage levels equal to 50% of the increase in the interest rate (expressed in basis points) of the increase in interest rate for the Senior Notes in connection with the terms of the Senior Notes Waiver, for such period as such increased interest rate shall be in effect with respect to the Senior Notes; and

WHEREAS, the Borrower and the other Credit Parties have offered to enter into such amendment and the Requisite Lenders have accepted such offer.

NOW, THEREFORE, in consideration of the premises and the agreements, provisions and covenants herein contained, the parties hereto agree as follows:

“(iii) from September 6, 2016 until December 6, 2016, a percentage, per annum, determined by reference to the Leverage Ratio in effect from time to time as set forth below:

(iv) thereafter, a percentage, per annum, determined by reference to the Leverage Ratio in effect from time to time as set forth below:

The parties hereto acknowledge and agree, for the avoidance of doubt, that any subsequent waiver or amendment to the Senior Notes Indenture entered into after August 29, 2016, that further amends or otherwise extends the deadline for delivery of the annual report required to be delivered by Section 4.03(a)(1) of the Senior Notes Indenture, or otherwise waives any default or event of default arising from the Borrower’s failure to comply with Section 4.03(a)(1) of the Senior Notes Indenture, in each case with respect

to the Fiscal Year ending December 31, 2015, shall constitute a Senior Notes Waiver subject to the provisions of Section 5.19 of the Credit Agreement.
