2.9Section 2.4 of the Credit Agreement is hereby amended by adding new clause (E) as follows:

“(E)    Notwithstanding anything to the contrary set forth herein, after the Borrower has delivered a Notice of Borrowing pursuant to this Section 2.4, any Lender that is incorporated in Canada (but not including any non-Canadian incorporated bank with a branch located in Canada) that has incurred charges (“Basel III Charges”) (which may include external charges incurred by such Lender or internal charges incurred by any business of such Lender as a result of related external charges incurred by such Lender) based on the “liquidity coverage ratio” under the proposals for risk-based capital

framework described by the Basel Committee on Banking Regulations and Supervisory Practices commonly known as Basel III, as amended, modified and supplemented and in effect from time to time or any replacement thereof (“Basel III”), or would incur Basel III Charges as of the relevant Borrowing Date, in respect of the transactions contemplated by this Agreement or any Advance funded hereunder by such Lender, by delivering a written notice (the “Delayed Funding Notice”) to the Borrower one (1) Business Day prior to the proposed Borrowing Date, such Lender may elect to delay the funding of its portion of the Advance by a period of up to 35 days; provided that only a Lender that is subject to the “liquidity coverage ratio” regulations under Basel III may deliver a Delayed Funding Notice. Each Delayed Funding Notice shall indicate (x) the portion of such Lender’s share of the requested Advance which will be subject to a delay (a “Delayed Amount”) and (y) the date (which, if such date is not a Business Day, then on the next succeeding Business Day) such delayed amount will be funded by such Lender (in respect of a Delayed Amount, the “Delayed Drawing Date”). Any Delayed Funding Notice shall be deemed a representation by the applicable Lender that it has incurred Basel III Charges in the respect of this Agreement or any Advance held by it hereunder. Notwithstanding anything to the contrary set forth herein, in the event a Lender elects to delay funding a portion of its share of an Advance in accordance with this Section 2.4(E), the Borrower shall (i) notify the Administrative Agent that such Lender will not be funding such portion of such Advance on the relevant requested Borrowing Date and that the relevant Delayed Amount will be deducted from the total amount of the requested Advance and (ii) offer the right to fund such Lender’s requested portion of such Advance to the other Lenders (so long as within their Unused Portion of the Commitments) prior to the Borrower funding (or cause to be funded) to itself, by way of an equity contribution, such Delayed Amount on the relevant requested Borrowing Date. In the event a Lender elects to delay funding a portion of its share of an Advance in accordance with this Section 2.4(E), such Lender’s share of the Unused Line Fees shall not accrue until such time as such Delayed Amount is funded by such Lender. For the avoidance of doubt, none of the Borrower, any Affiliate of the Borrower, the Administrative Agent, the Collateral Agent, the Custodian, the Securities Intermediary nor any other Lender shall be required to fund the relevant Delayed Amount to the Borrower on the relevant requested Borrowing Date. On the Delayed Drawing Date, the relevant Lender shall make available the Delayed Amount either (i) to the extent the Borrower funded the Delayed Amount by way of an equity contribution, to the Borrower by wire transferring the Delayed Amount, in immediately available funds, to an account of the Borrower as the Borrower may from time to time prior to the Delayed Drawing Date notify such Lender for such purpose, and, notwithstanding anything to the contrary set forth in this Agreement, the Borrower shall be permitted to transfer such Delayed Amount to Sunrun as reimbursement to the extent such Delayed Amount was funded by Sunrun to the Borrower on the Borrowing Date by way of an equity contribution or (ii) to the extent other Lenders funded the Delayed Amount, to such Lenders and such Lenders shall sell and assign at par amounts the advances related to the Delayed Amount to the delaying Lender such that each Lender

holds its pro rata share of all Advances outstanding after giving effect to such assignments.”

2.10Clause (F) of Section 2.5 of the Credit Agreement is deleted in its entirety and replaced with the following:

“(F) Unused Line Fees. On each Payment Date, the Borrower agrees to pay to the Paying Agent, for the benefit of each Committed Lender and as consideration for the Commitment of such Committed Lender (subject to Section 2.4(E) and Section 2.19(A)(i)), unused line fees in Dollars (the “Unused Line Fee”) for each day of the Availability Period occurring during the Interest Accrual Period ending on the day preceding such Payment Date, computed as (i) the Unused Line Fee Percentage for such day multiplied by (ii) the Unused Portion of the Commitments for such day.”

2.11Clause (xi) of Section 10.2 of the Credit Agreement is hereby amended by deleting “Borrowing Base”, “Eligible Solar Asset”, “Liquidity Reserve Account Required Balance” and “Post-PTO Reserve Account Required Balance” therein.

2.12Section 10.2 of the Credit Agreement is hereby amended by adding new clause (xii) as follows:

“(xii)    amend the definitions of “Borrowing Base”, “Eligible Solar Asset”, “Liquidity Reserve Account Required Balance”, “Post-PTO Reserve Account Required Balance”, or any of the component definitions of any thereof in a manner that would have the effect of increasing the Borrowing Base in any material respect without the written consent of all Lenders, except for any amendment to any such definition to (x) correct any scrivener error(s) or (y) clarify the meaning of any such definition;”

2.13Existing clauses (xii) and (xiii) of Section 10.2 of the Credit Agreement are hereby amended to be new clauses (xiii) and (xiv), respectively.
