(a) The Partnership covenants and agrees with the several Underwriters that the Partnership will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Partnership’s counsel and accountants in connection with the registration of the Shares under the Act and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriters; (iii) any road show expenses (except for road show expenses incurred by the Underwriters); (iv) the cost of printing or producing any Agreement among the Underwriters, this Agreement, the Blue Sky Memorandum, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Shares; (v) all expenses in connection with the qualification of the Shares for offering and sale under state securities laws as provided in Section 5(b) hereof, including the fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky survey; (vi) all fees and expenses in connection with listing the Shares on the NASDAQ; (vii) the filing fees incident to securing any required review by FINRA of the terms of the sale of the Shares (including related fees and expenses of counsel to the Underwriters in an amount that is not greater than $30,000); (viii) the cost of preparing any

certificates for the Shares; (ix) the cost and charges of any transfer agent, registrar or depositary; and (x) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section 7. It is understood, however, that, except as provided in this Section 7, and Sections 9 and 12 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, stock transfer taxes on resale of any of the Shares by them, any advertising expenses connected with any offers they may make, all travel expenses of the Underwriters and their representatives in connection with the road show, including 50% of the third-party cost of any aircraft chartered in connection with the road show, and all lodging expenses of the Underwriters and their representatives in connection with the road show.

(b) The provisions of this Section 7 shall not supersede or otherwise affect any agreement that the Partnership, Sponsors or Underwriters may otherwise have for the allocation of such expenses among themselves.

8. The obligations of the Underwriters hereunder, as to the Shares to be delivered at each Time of Delivery, shall be subject, in their discretion, to the condition that all representations and warranties and other statements of the Partnership herein are, as of the date hereof and at and as of such Time of Delivery, true and correct, the condition that the Partnership shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

(a) The Prospectus shall have been filed with the Commission pursuant to Rule 424(b) under the Act within the applicable time period prescribed for such filing by the rules and regulations under the Act and in accordance with Section 5(a) hereof; all material required to be filed by the Partnership pursuant to Rule 433(d) under the Act shall have been filed with the Commission within the applicable time period prescribed for such filing by Rule 433; if the Partnership has elected to rely upon Rule 462(b) under the Act, the Rule 462(b) Registration Statement shall have become effective by 10:00 p.m., Washington, D.C. time, on the date of this Agreement; no stop order suspending the effectiveness of the Registration Statement or any part thereof shall have been issued and no proceeding for that purpose shall have been initiated or, to the Partnership’s knowledge, threatened by the Commission; no stop order suspending or preventing the use of the Prospectus or any Issuer Free Writing Prospectus shall have been initiated or, to the Partnership’s knowledge, threatened by the Commission; and all requests for additional information on the part of the Commission shall have been complied with to your reasonable satisfaction.

(b) ▇▇▇▇▇▇ & ▇▇▇▇▇▇ L.L.P., counsel for the Underwriters, shall have furnished to you such written opinion or opinions, dated such Time of Delivery, in form and substance satisfactory to you, with respect to such matters you may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters.

(c) ▇▇▇▇▇ ▇▇▇▇▇ L.L.P., counsel for the Partnership, shall have furnished to you their written opinion or opinions (a form of each such opinion is attached as Annex I hereto), dated such Time of Delivery, in form and substance satisfactory to you.

(d) Skadden, Arps, Slate, ▇▇▇▇▇▇▇ & ▇▇▇▇ LLP, counsel for the Partnership, shall have furnished to you their written opinion or opinions (a form of each such opinion is attached as Annex II hereto), dated such Time of Delivery, in form and substance satisfactory to you.

(e) On the date of the Prospectus at a time prior to the execution of this Agreement, at 9:30 a.m., New York City time, on the effective date of any post-effective amendment to the Registration Statement filed subsequent to the date of this Agreement and also at each Time of Delivery, each of Ernst & Young LLP, PricewaterhouseCoopers LLP and ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇, LLC shall have furnished to you a letter or letters, dated the respective dates of delivery thereof, in form and substance satisfactory to you.

(f) (i) The YieldCo Entities, taken as a whole, shall not have sustained, since the date of the latest audited financial statements included in the Pricing Prospectus, any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Pricing Prospectus, and (ii) since the respective dates as of which information is given in the Pricing Prospectus there shall not have been any change in the equity interests or long-term debt or any Material Adverse Effect, otherwise than as set forth or contemplated in the Pricing Prospectus, the effect of which, in any such case described in clause (i) or (ii), is in your judgment so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares being delivered at such Time of Delivery on the terms and in the manner contemplated in the Prospectus.

(g) There are no debt securities or preferred stock of, or guaranteed by, any YieldCo Entity that are rated by a “nationally recognized statistical rating organization,” as such term is defined in Section 3(a)(62) of the Exchange Act.

(h) On or after the Applicable Time there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the NASDAQ; (ii) a suspension or material limitation in trading in the Partnership’s securities on the NASDAQ; (iii) a general moratorium on commercial banking activities declared by either Federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency

or war or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in your judgment makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares being delivered at such Time of Delivery on the terms and in the manner contemplated in the Prospectus.

(i) The Shares to be sold at such Time of Delivery shall have been approved for quotation upon notice of issuance on the NASDAQ.

(j) The Partnership shall have obtained and delivered to the Underwriters executed copies of agreements from the officers, directors and shareholders or unitholders, as applicable, of OpCo, the Partnership and the General Partner set forth on Schedule III, substantially to the effect set forth in Section 5(e)(1) hereof in form and substance satisfactory to you.

(k) The Partnership shall have complied with the provisions of Section 5(c) hereof with respect to the furnishing of prospectuses on the New York Business Day next succeeding the date of this Agreement.

(l) The Partnership shall have furnished or caused to be furnished to you at such Time of Delivery certificates of officers of the Partnership reasonably satisfactory to you as to the accuracy of the representations and warranties of the Partnership herein at and as of such Time of Delivery, as to the performance by the Partnership of all of its obligations hereunder to be performed at or prior to such Time of Delivery, as to the matters set forth in subsections (a) and (f) of this Section 8 and as to such other matters as you may reasonably request.

(m) The Organizational Transactions, other than OpCo entering into any of the Debt Facilities, shall have been consummated, or will be consummated upon or substantially concurrently with the issuance of the Shares and payment therefore in accordance with the terms of this Agreement, and the Partnership shall have provided evidence reasonably satisfactory to the Underwriters evidencing such consummation, including the satisfaction of any consents, notices or filings required in connection therewith.

(n) The Transaction Documents shall have been executed and the Partnership shall have provided the Underwriters execution copies thereof.

9. (a) The YieldCo Parties will jointly and severally indemnify and hold harmless each Underwriter, its officers, directors, employees and selling agents, and each affiliate of any Underwriters who has participated in the distribution of the Shares as underwriters and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the

Registration Statement, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that none of the YieldCo Parties shall be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to any of the YieldCo Parties by any Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by or on behalf of the Underwriters consists of the information described in subsection (f) of this Section 9.

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the YieldCo Parties, each of the directors and officers of the General Partner who sign the Registration Statement and each person who controls the Partnership within the meaning of either the Act or the Exchange Act against any losses, claims, damages or liabilities to which the YieldCo Parties may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to any of the YieldCo Parties by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by or on behalf of the Underwriters consists of the information described in subsection (f) of this Section 9; and will reimburse any of the YieldCo Parties for any legal or other expenses reasonably incurred by such YieldCo Entity in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection unless and to the extent it has been materially prejudiced through the forfeiture by the indemnifying party of substantial rights and defenses. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel (other than local counsel) or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation, except, in any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the contrary; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify each indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested that an indemnifying party reimburse the indemnified party for fees and expenses of counsel as contemplated by this paragraph, the indemnifying party shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the indemnifying party of such request and (ii) the indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the written consent of the

indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party, in form and substance reasonably satisfactory to such indemnified party, from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the YieldCo Parties on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of any of the YieldCo Parties on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by any of the YieldCo Parties on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Partnership bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by any of the YieldCo Parties on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The YieldCo Parties and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in

this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the YieldCo Parties under this Section 9 shall be in addition to any liability which the YieldCo Parties may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the General Partner (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the General Partner) and to each person, if any, who controls any of the YieldCo Parties within the meaning of the Act.

(f) The YieldCo Parties acknowledge that the last paragraph of the cover page regarding the delivery of the Shares and under the caption “Underwriting,” (i) the sentences related to concessions and (ii) the paragraphs related to stabilization and syndicate covering transactions in the Registration Statement, the Pricing Disclosure Package and the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion therein.

10. (a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Partnership shall be entitled to a further period of thirty-six hours within which to procure another party or other parties reasonably satisfactory to you to purchase such Shares on such terms. In the event that, within the respective prescribed periods, you notify the Partnership that you have so arranged for the purchase of such Shares, or the Partnership notifies you that it has so arranged for the purchase of such Shares, you or the Partnership shall have the right to

postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Partnership agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term “Underwriter,” as used in this Agreement, shall include any person substituted under this Section 10 with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Partnership as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, then the Partnership shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Partnership as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, or if the Partnership shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligations of the Underwriters to purchase and of the Partnership to sell the Optional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Partnership, except for the expenses to be borne by the Partnership and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11. The respective indemnities, rights of contribution, agreements, representations, warranties and other statements of the YieldCo Parties and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or any of the YieldCo Entities, or any officer or director or controlling person of any of the YieldCo Entities, and shall survive delivery of and payment for the Shares.

12. If this Agreement shall be terminated pursuant to Section 10 hereof, the YieldCo Entities shall not then be under any liability to any Underwriter, except as provided in Sections 7 and 9 hereof; but, if for any other reason (other than those set forth in clauses (i), (iii), (iv) or (v) of Section 8(h)), any Shares are not delivered by or on behalf of the Partnership as provided herein, the Partnership will reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Partnership shall then be under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

13. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by you jointly or by ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co. or Citigroup Global Markets Inc. on behalf of you as the Representatives.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to you as the Representatives in care of ▇▇▇▇▇▇▇, Sachs & Co., ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇-▇▇▇▇, Attention: Registration Department, with a copy to Citigroup Global Markets Inc., ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: General Counsel (facsimile: (▇▇▇) ▇▇▇-▇▇▇▇); and if to the Partnership, shall be delivered or sent by mail, telex or facsimile transmission to the address of the Partnership set forth in the Registration Statement, Attention: Chief Executive Officer; provided, however, that any notice to an Underwriter pursuant to Section 9(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Partnership by you upon request; provided, however, that notices under subsection 5(e) shall be in writing, and if to the Underwriters, shall be delivered or sent by mail, telex or facsimile transmission to you as the Representatives at ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co., ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇-▇▇▇▇, Attention: Control Room, with a copy to Citigroup Global Markets Inc., ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: General Counsel (facsimile: (▇▇▇) ▇▇▇-▇▇▇▇). Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Partnership, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

14. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the YieldCo Entities and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the YieldCo Entities and each person who controls any of the YieldCo Entities or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

15. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

16. The Partnership acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Partnership, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction, each Underwriter is acting solely as a principal and not the agent or fiduciary of the Partnership, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Partnership with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Partnership on other matters) or any other obligation to the Partnership except the obligations expressly set forth in this Agreement and (iv) the Partnership has consulted its own legal and financial advisors to the extent it deemed appropriate. The Partnership agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Partnership, in connection with such transaction or the process leading thereto.

17. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Partnership and the Underwriters, or any of them, with respect to the subject matter hereof.

18. THIS AGREEMENT AND ANY MATTERS RELATED TO THIS TRANSACTION SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK. Each of the YieldCo Parties agrees that any suit or proceeding arising in respect of this Agreement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and each of the YieldCo Parties agrees to submit to the jurisdiction of, and to venue in, such courts.

19. Each of the YieldCo Parties and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

20. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

21. Notwithstanding anything herein to the contrary, the Partnership is authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the transactions contemplated by this Agreement and the Transaction Documents and all materials of any kind (including tax opinions and other tax analyses) provided to the Partnership relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

If the foregoing is in accordance with your understanding, please sign and return counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof shall constitute a binding agreement between each of the Underwriters, on the one hand, and the YieldCo Parties, on the other hand. It is understood that your acceptance of this letter on behalf of each of the Underwriters is pursuant to the authority set forth in a form of Agreement among Underwriters, the form of which shall be submitted to the Partnership for examination upon request, but without warranty on your part as to the authority of the signers thereof.

To the knowledge of such counsel, neither the filing of the Registration Statement nor the offering or sale of the Shares as contemplated by the Underwriting Agreement gives rise to any rights for or relating to the registration of any Class A Shares or other securities of the Partnership, except such rights as have been waived or satisfied.

17. Investment Company Act. The Partnership is not now, and immediately following the sale of the Shares to be sold by the Partnership pursuant to the Underwriting Agreement and application of the net proceeds from such sale as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus under the caption “Use of Proceeds” will not be, an “investment company” as defined in the Investment Company Act.

18. Non-contravention. None of (i) the execution and delivery by the Partnership of the Underwriting Agreement or consummation of the issuance and sale of the Shares contemplated thereby, or (ii) the execution and delivery of the Transaction Documents by the Opinion Parties that are parties thereto or consummation of the transactions contemplated thereby (excluding consummation of the Sponsors’ Contribution and the Debt Facilities) by the Opinion Parties party thereto: (A) conflicts with the organizational documents of any Opinion Parties, (B) constitutes a violation of, or a default under, any Scheduled Agreements, or (C) violates the DRULPA, the DLLCA or federal law, which violations or defaults, in the case of clauses (B) or (C), would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or to materially impair the ability of any of the Opinion Parties to consummate the

transactions contemplated by the Transaction Documents (excluding consummation of the Sponsors’ Contribution and the Debt Facilities) or any other transactions provided for in the Underwriting Agreement; provided, however, that such counsel need express no opinion in this paragraph 17 with respect to federal or state securities laws and other anti-fraud laws.

19. No Consents. No permit, consent, approval, authorization, order, registration or qualification (“consent”) of or with any Delaware or federal court, governmental agency or body having jurisdiction over any of the Opinion Parties or their properties or assets, is required in connection with (i) the offering, issuance or sale by the Partnership of the Shares, (ii) the execution and delivery of the Underwriting Agreement and the Transaction Documents by the Opinion Parties party thereto or (iii) the consummation of the transactions contemplated by the Transaction Documents (excluding consummation of the Sponsors’ Contribution and the Debt Facilities) by the Opinion Parties party thereto, other than (a) registration of the Shares under the Act or the Exchange Act (as to which such counsel need not express an opinion), (b) any necessary qualification under the securities or blue sky laws of the various jurisdictions in which the Shares are being offered by the Underwriters (as to which such counsel need not express an opinion), (c) under the by-laws and rules and regulations of FINRA (as to which such counsel need not express an opinion), (d) consents that have been obtained and (e) where the failure to obtain such consent would neither reasonably be expected to have a Material Adverse Effect nor materially impair the ability of the Opinion Parties to consummate the transactions provided for in the Underwriting Agreement or the Transaction Documents (excluding consummation of the Sponsors’ Contribution and the Debt Facilities).

20. Effectiveness of the Registration Statement. The Registration Statement has been declared effective under the Securities Act; any required filing of the Prospectus, and any supplements thereto, with the Commission pursuant to Rule 424(b) has been made in the manner and within the time period required by Rule 424(b); to such counsel’s knowledge, no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings or examinations for that purpose have been instituted by the Commission.

21. Description of Class A Shares. The statements in the Prospectus and the Pricing Disclosure Package under the captions “Description of the Shares,” “Our Cash Distribution Policy and Restrictions on Distributions,” “Provisions of Our Partnership Agreement and the OpCo Limited Liability Company Agreement Relating to Cash Distributions,” “Material Provisions of the 8point3 Partners Partnership Agreement” and “Material Provisions of the OpCo Limited Liability Company Agreement,” insofar as such statements constitute descriptions or summaries of the terms of the Class A Shares, are accurate in all material respects.

22. Descriptions and Summaries. The statements in the Prospectus and the Pricing Disclosure Package under the captions “Our Cash Distribution Policy and Restrictions on Distributions,” “Certain Relationships and Related Party Transactions,” “Business—Regulatory Matters” and “Business—Environmental Matters” (only with respect to environmental regulation in the United States), “Material Provisions of the 8point3 Partners Partnership Agreement,” “Material Provisions of the OpCo Limited Liability Company Agreement” and “Certain U.S. Federal Income and Estate Tax Consequences to Non-U.S. Holders,” insofar as such statements purport to constitute summaries of certain provisions of the documents, federal laws of the United States, the DRULPA or the DLLCA, are accurate summaries of the provisions of such documents, federal laws of the United States, the DRULPA or the DLLCA in all material respects.

In rendering such opinion, such counsel may (i) rely in respect of matters of fact upon certificates of officers and employees of the Opinion Parties and upon information obtained from public officials, (ii) assume that all documents submitted to such counsel as originals are authentic, that all copies submitted to such counsel conform to the originals thereof, and that the signatures on all documents examined by such counsel are genuine, (iii) state that its opinion is limited to matters governed by federal law, the DRULPA and the DLLCA, (iv) with respect to the opinions expressed as to the good standing or due qualification or registration as a foreign limited partnership, foreign limited liability company or foreign general partnership, as the case may be, of the Opinion Parties, state that such opinions are based upon certificates of good standing provided by the Secretary of State of the state of formation and certificates of foreign qualification or registration provided by the Secretary of State of the states listed on an annex to be attached to such counsel’s opinion (each of which shall be dated as of a date not more than fourteen days prior to the applicable Time of Delivery and shall be provided to counsel to the Underwriters), (v) state that they express no opinion with respect to (A) any permits to own or operate any real or personal property or (B) state or local taxes or tax statutes to which any of the limited partners of the Partnership or any of the Opinion Parties may be subject, and (vi) with respect to the opinions expressed in paragraphs 8, 10, 12 and 14 relating to the existence of any Lien for which a financing statement under the Uniform Commercial Code is on file, rely solely upon such counsel’s review of reports, dated as of recent dates, prepared by CT Corporation, purporting to describe all financing statements on file as of the dates thereof in the office of the Secretary of State of the State of Delaware, naming Holdings or either Sponsor, as applicable, as debtor.

In addition, such counsel shall make a statement to the following effect:

We have reviewed the Registration Statement, the Pricing Disclosure Package and the Prospectus and have participated in conferences with officers and other representatives of the Partnership, representatives of the Partnership’s independent registered public accountants, co-counsel for the Partnership, and with your representatives and your counsel at which the contents of the Registration Statement, the Pricing Disclosure Package, the Prospectus and related matters were discussed. The purpose of our professional engagement was not to establish or confirm factual matters set forth in the Registration Statement, the Pricing Disclosure Package or the Prospectus, and we have not undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Registration Statement, the Pricing Disclosure Package and the Prospectus involve matters of a non-legal nature. Accordingly, we are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or included in the Registration Statement, the Pricing Disclosure Package and the Prospectus (except to the extent stated in paragraphs 21 and 22 above). Subject to the foregoing and on the basis of the information we gained in the course of performing the services referred to above, we advise you that:

(a) the Registration Statement, at the time it became effective, the Preliminary Prospectus, as of the Applicable Time, and the Prospectus, as of its date and the date hereof, appear on their face to be appropriately responsive in all material respects to the requirements of the Securities Act and the rules and regulations of the Commission thereunder; and

(b) nothing came to our attention that caused us to believe that:

(1) the Registration Statement, at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(2) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

(3) the Prospectus, as of its date or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that in each case we have not been asked to, and do not, express any belief with respect to (a) the financial statements and schedules or other financial or accounting information contained or included therein or omitted therefrom, or (b) representations and warranties and other statements of fact contained in the exhibits to the Registration Statement.

This letter is being furnished to you pursuant to Section 8(d) of the Underwriting Agreement. Neither the delivery of this letter nor anything in connection with the preparation, execution or delivery of the Underwriting Agreement or the agreements contemplated thereby is intended to create or shall create an attorney-client relationship with you or any other party except Our Client.

In the above capacity, we have reviewed the registration statement on Form S-1 (File No. 333-202634) of the Partnership relating to the Securities filed on March 10, 2015 with the Securities and Exchange Commission (the “Commission”), under the Securities Act of 1933 (the “Securities Act”) and

Re: 8point3 Energy Partners LP—Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an Underwriting Agreement on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with 8point3 Energy Partners LP, a Delaware limited partnership (the “Partnership”), providing for a public offering of Class A shares representing limited partner interests in the Partnership (the “Shares”) pursuant to a Registration Statement on Form S-1 to be filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any Class A shares of the Partnership, or any options or warrants to purchase any Class A shares of the Partnership, or any securities convertible into, exchangeable for or that represent the right to receive Class A shares of the Partnership (including common units and subordinated units representing limited liability company interests in 8point3 Operating Company, LLC, a Delaware limited liability company (“OpCo”)), whether now owned or hereinafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the SEC (collectively the “Undersigned’s Shares”). The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale

or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Shares. If the undersigned is an officer or director of the issuer, the undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed Shares the undersigned may purchase in the offering.

The initial Lock-Up Period will commence on the date of this Lock-Up Agreement and continue for 180 days after the public offering date set forth on the final prospectus used to sell the Shares (the “Public Offering Date”) pursuant to the Underwriting Agreement.

If the undersigned is an officer or director of 8point3 General Partner, LLC, a Delaware limited liability company and the general partner of the Partnership (the “General Partner”), (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of Class A shares of the Partnership, the Representatives will notify the Partnership of the impending release or waiver, and (ii) the Partnership has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this letter to the extent and for the duration that such terms remain in effect at the time of the transfer.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Shares (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, or (iii) with the prior written consent of the Representatives on behalf of the Underwriters; provided, however, that in the case of clause (i) or (ii) above, it shall be a condition that such transfers are not required to be reported with the SEC on Form 4 in accordance with Section 16 of the Securities Exchange Act of 1934, as amended, and the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. In addition, notwithstanding the foregoing, if the undersigned is a corporation, the

corporation may transfer equity interests of the Partnership or OpCo to any wholly-owned subsidiary of such corporation; provided, however, that in any such case, it shall be a condition to the transfer that the transferee execute an agreement stating that the transferee is receiving and holding such equity interests subject to the provisions of this Agreement and there shall be no further transfer of such equity interests except in accordance with this Agreement, and provided further that any such transfer shall not involve a disposition for value. Furthermore, the undersigned may sell Class A shares of the Partnership purchased by the Undersigned on the open market following the Public Offering Date if and only if (a) such sales are not required to be reported in any public report or filing with the SEC, or otherwise and (b) the undersigned does not otherwise voluntarily effect any public filing or report regarding such sales. The undersigned now has, and, except as contemplated by clause (i), (ii), or (iii) above, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned’s Shares, free and clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Partnership’s transfer agent and registrar against the transfer of the Undersigned’s Shares except in compliance with the foregoing restrictions.

The undersigned understands that the Partnership and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.

Very truly yours,
