PROMISSORY NOTE

$50,000,000

8point3 Operating Company, LLC, a Delaware limited liability company (“Payor”), for value received, hereby unconditionally promises to pay to the order of First Solar Asset Management, LLC, a Delaware limited liability company (“Seller”), on or before the date that is six (6) months after the Maturity Date (the “Note Maturity Date”) the principal amount of Fifty Million Dollars ($50,000,000) (the “Loan”), together with accrued interest thereon at a rate of (a) six percent (6%) per annum (i) in respect of all amounts outstanding under this Promissory Note (this “Note”) upon the occurrence and during the continuance of any Specified Event of Default (as defined herein), and (ii) in respect of the amount of any interest payment accrued as a PIK (as defined herein), and (b) four percent (4%) per annum in respect of all other amounts outstanding under this Note (the “Interest Rate”).

Capitalized terms used herein and not otherwise defined herein shall have the meaning given to such terms in that certain Credit and Guaranty Agreement, dated as of June 5, 2015 (as amended, restated, supplemented or otherwise modified through the date hereof, the “Credit Agreement”), among Payor, 8point3 Energy Partners LP, certain subsidiaries of Payor, Credit Agricole Corporate and Investment Bank, as administrative agent and collateral agent, the lenders party thereto and the other agents party thereto.

1.Payments.

(a)Interest under this Note shall be due and payable quarterly in arrears on the tenth (10^th) Business Day of March, June, September and December with respect to the period ending on the last day of the immediately preceding Fiscal Quarter, commencing on the first such date to occur after the date hereof (each, a “Note Interest Payment Date”); provided, that such amounts shall be paid solely from amounts that would, at such time, otherwise be permitted to be distributed as a Restricted Junior Payment by Payor pursuant to Section 6.4(c) of the Credit Agreement (“Distributable Cash”), such amounts, in any such Fiscal Quarter, not to exceed the Quarterly Prepayment Threshold (as defined herein) for such Fiscal Quarter; provided, further, that, to the

extent Payor does not have sufficient Distributable Cash to pay any such Interest Payment in cash, the portion thereof not paid in cash shall be accrued as a payment-in-kind (“PIK”) and added to the outstanding balance of this Note; provided, further, that the entire unpaid balance of accrued interest, together with the entire unpaid principal balance of this Note if not sooner paid, shall be due and payable in full on the Note Maturity Date.

(b)Except as otherwise expressly provided herein, all repayments (excluding, for the avoidance of doubt, prepayments) hereunder shall include the payment of the unpaid balance of all interest accrued under the Note to and including the date of such repayment.  All repayments and any prepayments pursuant to Section 2(a)(i) made by Payor hereunder shall be applied first to accrued and unpaid interest and then to unpaid principal.  Interest hereunder shall be computed on the basis of a 360-day year for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable.  All repayments and prepayments by Payor of principal and all payments by Payor of interest, and all other sums due under this Note shall be made without deduction, setoff, abatement, suspension, deferment, defense or counterclaim, on or before the due date of repayment or payment, and shall be paid in lawful money of the United States of America, in immediately available funds on the day when payment shall become due, at the principal office of Seller (or at such other place as Seller may designate in writing).  

(c)If at any time any payment made by Payor under this Note is rescinded or must otherwise be restored or returned upon the insolvency, bankruptcy or reorganization of Payor or otherwise, Payor’s obligation to make such payment shall be reinstated as though such payment had not been made.

(d)Upon payment in full of the principal of and interest on this Note and all other sums due from Payor to Seller under the terms of this Note or upon any prepayment, this Note shall be canceled and returned to Payor and shall be of no further operation or effect.  The obligation of Payor to make the payments required to be made on this Note and to perform and observe the other agreements on its part contained herein shall be absolute and unconditional and shall not be subject to diminution by setoff, counterclaim, abatement or otherwise.

(a)Mandatory Prepayments.  Payor shall prepay amounts outstanding under this Note:

(b)A “Note Event of Default” hereunder shall occur if (i) Payor shall fail to pay any amount of interest on or principal of the Loan when and as due hereunder (it being understood that any interest payment accrued as a PIK shall not constitute such a failure to pay interest on the Loan), or (ii) Payor shall fail to comply with or shall breach any covenant or other provision set forth in this Note.  

7.Remedies.  (a) From and after the earlier of (i) the Termination Date (as defined in Schedule 1.1(E) of the Credit Agreement and the Subordination Agreement); and (ii) the Note Maturity Date (but, in the event the Note Maturity Date occurs prior to the Termination Date, solely to the extent permitted pursuant to the Subordination Agreement), upon the occurrence of any Note Event of Default, or (b) upon the occurrence of any Specified Event of Default; and, in each case, at any time thereafter during the continuance thereof, Seller may at its option, by written notice to Payor (x) declare the entire principal amount of this Note, together with all accrued interest thereon and all other amounts payable hereunder, immediately due and payable; and/or (y) exercise any or all of its rights, powers or remedies available at law or in equity; provided, however, that upon the occurrence of any Specified Event of Default, the principal of and accrued interest on the Loan shall become immediately due and payable without any notice, declaration or other act on the part of Seller.
