Ladies and Gentlemen: 
 Sunnova Energy
International Inc., a Delaware corporation (the “Company”), proposes, subject to the terms and conditions set forth in this agreement (this “Agreement”), to issue and sell to the several initial purchasers named in
Schedule 1 hereto (the “Purchasers”), for whom Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC (the “Representatives”) are acting as representatives of the Purchasers, $500,000,000
aggregate principal amount of its 0.25% Convertible Senior Notes due 2026 (the “Firm Securities”), and, at the option of the Purchasers, up to an additional $75,000,000 aggregate principal amount of its 0.25% Convertible Senior Notes
due 2026 (the “Option Securities”), solely to cover sales in excess of the Firm Securities, if and to the extent that the Purchasers shall exercise the option to purchase such Option Securities granted to the Purchasers in
Section 1 hereof. The Firm Securities and the Option Securities are herein referred to collectively as the “Securities.” The Securities will be convertible into shares of common stock, par value $0.0001 per share,
of the Company (the “Common Stock”), or a combination of cash and Common Stock, at the Company’s election, on the terms, and subject to the conditions, set forth in the Indenture, and any shares of Common Stock into which the
Securities are convertible are referred to herein as the “Underlying Securities.” The Securities will be issued pursuant to an Indenture (the “Indenture”) to be dated as of the Closing Date (as defined in
Section 1(c)), between the Company and Wilmington Trust, National Association, as trustee (the “Trustee”). 

Unless otherwise required by the context, references herein to the “subsidiaries” of the Company refer to the direct or indirect
subsidiaries of the Company. 












 In connection with the offering of the Firm Securities, the Company is entering into capped
call transactions with one or more counterparties, which may include the Purchasers or affiliates thereof (the “Option Counterparties”), pursuant to separate capped call transaction confirmations (the “Base Capped Call
Confirmations”), each dated the date hereof, and in connection with any exercise by the Purchasers of their option to purchase any Option Securities, the Company and the Option Counterparties may enter into additional capped call transactions
pursuant to additional capped call transaction confirmations (the “Additional Capped Call Confirmations”) with each of the Option Counterparties to be dated the date on which the Purchasers exercise their option to purchase such Option
Securities, if any. The Base Capped Call Confirmations and the Additional Capped Call Confirmations are referred to herein collectively as the “Capped Call Confirmations.” 

For the purposes of this Agreement, “Applicable Time” means 9:30 p.m. New York City time on the date of this Agreement. 

 

	1.	 Purchase of the Securities. 



 

	 	(a)	 The Company agrees to issue and sell the Securities, and each Purchaser, on the basis of the representations,
warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally, and not jointly, to purchase at a purchase price of 97.5% of the principal amount thereof plus accrued interest, if any, from May 20,
2021 to the Closing Date (the “Purchase Price”), from the Company, the respective principal amount of Securities set forth opposite such Purchaser’s name in Schedule 1 hereto. 



 

	 	(b)	 In addition, on the basis of the representations, warranties and agreements set forth herein, and subject to
the conditions set forth herein, the Company hereby grants to the Purchasers an option to purchase, severally, and not jointly, at their election, up to $75,000,000 aggregate principal amount of Option Securities at the Purchase Price. Such option
may be exercised in whole or in part at any time or from time to time, by written notice from the Purchasers to the Company setting forth the aggregate principal amount of Option Securities to be purchased and the date on which such Option
Securities are to be delivered, as determined by you but in no event earlier than the Closing Date or, unless you and the Company otherwise agree in writing, earlier than two or later than ten business days after the date of such notice;
provided, in no event shall the delivery date of the Option Securities be later than the last day of the 13 calendar day period beginning on, and including, the Closing Date (the “Option Period”). The principal amount of Option
Securities to be purchased by each Purchaser shall be the same percentage of the total principal amount of Option Securities to be purchased by all Purchasers as such Purchaser is purchasing of the Firm Securities, subject to such adjustments as you
in your absolute discretion shall make to eliminate any fraction of $1,000 principal amount of Securities. 


  

	 	(c)	 The Securities to be purchased by each Purchaser hereunder will be represented by one or more global Securities
in book-entry form which will be deposited by or on behalf of the Company with The Depository Trust Company (“DTC”) or its designated custodian. The Company will deliver the Securities to the




  
 2 














	 	
Representatives, for the account of each Purchaser, against payment by or on behalf of such Purchaser of the purchase price therefor by wire transfer in Federal (same day) funds, by causing DTC
to credit the Securities to the accounts of the Representatives at DTC. The Company will cause the certificates representing the global Securities to be made available to the Representatives not later than 1:00 p.m. New York City Time, on the
business day prior to the Closing Date or any Additional Closing Date (as each is defined in this Section 1(c)) at the office of Baker Botts L.L.P., 910 Louisiana Street, Houston, Texas 77002 (the “Closing Location”). The time
and date of such delivery and payment shall be 10:00 a.m., New York City time, on May 20, 2021 or such other time and date as the Representatives and the Company may agree upon in writing and, with respect to the Option Securities, 10:00
a.m., New York City time, on the date specified by the Representatives in the written notice given by the Representatives of the Purchasers’ election to purchase such Option Securities at least two business days preceding the anticipated
delivery and payment, or such other time and date as the Representatives and the Company may agree upon in writing. Such time and date for such payment of the Firm Securities is herein called the “Closing Date,” and any such time and date
for such payment of any Option Securities, if other than the Closing Date, is herein called an “Additional Closing Date.” 

  

	 	(d)	 The documents to be delivered at the Closing Date or any Additional Closing Date, as the case may be, by or on
behalf of the parties hereto pursuant to Section 5 hereof, including the cross-receipt for the Securities and any additional documents requested by the Purchasers pursuant to Section 5(o) hereof, will be delivered at such time and date at
the Closing Location, and the Securities will be delivered at the office of DTC (or its designated custodian), all at the Closing Date or any Additional Closing Date, as the case may be. For the purposes of this Section 1(d), “New York
Business Day” shall mean each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close. 



 

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

	 	(a)	 Indemnification of the Purchasers by the Company. The Company agrees to indemnify and hold harmless each
Purchaser, its affiliates, directors and officers and each person, if any, who controls such Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims,
damages and liabilities (including, without limitation, reasonable and documented out-of-pocket legal fees and other expenses incurred in connection with any suit,
action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon any untrue statement or alleged untrue statement of a material fact contained or incorporated by reference in
any Preliminary Offering Memorandum, the Pricing Term Sheet, the Pricing Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto, any Company Supplemental Disclosure Document, any Permitted General Solicitation Material
or arise out of or are based upon the omission or alleged omission to state therein a material fact or necessary in order to make the statements therein not misleading; provided, however, that the Company shall not 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 any Preliminary Offering Memorandum, the Pricing Term
Sheet, the Pricing Disclosure Package, the Offering Memorandum or any such amendment or supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material, in reliance upon and in conformity with written
information furnished to the Company by any Purchaser through the Representatives expressly for use therein; it being understood and agreed that the only such information furnished by any Purchaser consists of the information described as such in
Section 6(b) hereof. 


  

	 	(b)	 Indemnification of the Company by the Purchasers. Each Purchaser, severally and not jointly, will
indemnify and hold harmless the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all
losses, claims, damages and liabilities (including, without limitation, reasonable and documented out-of-pocket legal fees and other expenses incurred in connection with
any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Preliminary
Offering Memorandum, the Pricing Term Sheet, the Pricing Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto, or 



  
 25 














	 	
any Company Supplemental Disclosure Document, any Permitted General Solicitation Material or arise out of or are based upon the omission or alleged omission to state therein a material fact
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 any Preliminary Offering Memorandum, the
Pricing Term Sheet, the Pricing Disclosure Package, the Offering Memorandum or any such amendment or supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material, in reliance upon and in conformity with
written information furnished to the Company by such Purchaser through the Representatives expressly for use therein; it being understood and agreed upon that the only such information furnished by any Purchaser consists of the following information
in the Preliminary Offering Memorandum and the Offering Memorandum furnished on behalf of each Purchaser: the information contained in the second and third sentences of the paragraph under the caption “Plan of Distribution—Notes Are Not
Being Registered” and the information contained in the first paragraph under the caption “Plan of Distribution—Price Stabilization, Short Positions.” 


 

	 	(c)	 Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory
investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to the preceding paragraphs of this Section 6, such person (the “Indemnified Person”) shall
promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under
the preceding paragraphs of this Section 6 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify
the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under the preceding paragraphs of this Section 6. If any such proceeding shall be brought or asserted against an
Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel
to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 6 that the Indemnifying Person may designate in such proceeding and shall pay the reasonable and documented out-of-pocket fees and expenses in such proceeding and shall pay the reasonable and documented
out-of-pocket fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person 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 Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying
Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different
from or in addition 



  
 26 














	 	
to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified
Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding
or related proceeding in the same jurisdiction, be liable for the reasonable and documented out-of-pocket fees and expenses of more than one separate firm (in addition
to any local counsel) for all Indemnified Persons, and that all such reasonable and documented out-of-pocket fees and expenses shall be paid or reimbursed as they are
incurred. Any such separate firm for any Purchaser, its affiliates, directors and officers and any control persons of such Purchaser shall be designated in writing by the Representatives and any such separate firm for the Company, its directors, its
officers and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent,
the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an
Indemnifying Person reimburse the Indemnified Person for reasonable and documented out-of-pocket fees and expenses of counsel as contemplated by this paragraph, the
Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (x) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (y) the
Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of
any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (1) includes an unconditional
release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (2) does not include any statement as to or any
admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person. 

  

	 	(d)	 Contribution. If the indemnification provided for in this Section 6 is unavailable to or
insufficient to hold harmless an indemnified party under Sections 6(a) or 6(b) above in respect of any losses, claims, damages or liabilities 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 (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Purchasers on the other hand from the
offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, then in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the
relative fault of the Company on the one hand and the Purchasers on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities,




  
 27 














	 	
as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Purchasers on the other hand shall be deemed to be in the same
respective proportions as the total net proceeds from the offering (before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Purchasers in connection therewith bear to
the aggregate offering price of the Securities. 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 the Company on the one hand or the Purchasers on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The
Company and the Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 6(d) were determined by pro rata allocation (even if the Purchasers 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 Section 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities referred to
above in this Section 6(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
Section 6(d), no Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased by it pursuant to this Agreement and distributed to investors were offered to investors
exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Purchasers’ obligations in this Section 6(d) to contribute
are several in proportion to their respective purchase obligations and not joint. 

  

	 	(e)	 Limitation on Liability. The Company and the Purchasers agree that it would not be just and equitable if
contribution pursuant to paragraph (e) above were determined by pro rata allocation (even if the Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable
considerations referred to in paragraph (e) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (e) above shall be deemed to include, subject to the
limitations set forth above, any reasonable and documented out-of-pocket legal or other expenses incurred by such Indemnified Person in connection with any such action
or claim. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The
Purchasers’ obligations to contribute pursuant to paragraphs (e) and (f) are several in proportion to their respective purchase obligations hereunder and not joint. 



 

	 	(f)	 Non-Exclusive Remedies. The remedies provided for in this
Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. 



  
 28 














	7.	 Effectiveness of Agreement. This Agreement shall become effective as of the date first written above.



  

	8.	 Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by
notice to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date or, in the case of the Option Securities, prior to any Additional Closing Date (i) trading generally shall have been suspended or
materially limited on or by any of the Exchange or The Nasdaq Stock Market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak
or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to
proceed with the offering, sale or delivery of the Securities on the Closing Date or any Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Offering
Memorandum. 


  

	9.	 Defaulting Purchaser. 



 

	 	(a)	 If any Purchaser shall default in its obligation to purchase the Securities which it has agreed to purchase
hereunder, you may in your discretion arrange for you or another party or other parties to purchase such Securities on the terms contained herein. If within 36 hours after such default by any Purchaser you do not arrange for the purchase of such
Securities, then the Company shall be entitled to a further period of 36 hours within which to procure another party or other parties reasonably satisfactory to you to purchase such Securities on such terms. In the event that, within the respective
prescribed periods, you notify the Company that you have so arranged for the purchase of such Securities, or the Company notifies you that it has so arranged for the purchase of such Securities, you or the Company shall have the right to postpone
the Closing Date or any Additional Closing Date for a period of not more than seven days (provided, that any Additional Closing Date must occur during the Option Period (after giving effect to any such postponement)), in order to effect whatever
changes may thereby be made necessary in the Offering Memorandum, or in any other documents or arrangements, and the Company agrees to prepare promptly any amendments or supplements to the Offering Memorandum which in your opinion may thereby be
made necessary. The term “Purchaser” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Securities.



  

	 	(b)	 If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or
Purchasers by you and the Company as provided in Section 9(a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal
amount of all the Securities, then the Company shall have the right to require each 



  
 29 














	 	
non-defaulting Purchaser to purchase the principal amount of Securities which such Purchaser agreed to purchase hereunder and, in addition, to require each
non-defaulting Purchaser to purchase its pro rata share (based on the principal amount of Securities which such Purchaser agreed to purchase hereunder) of the Securities of such defaulting Purchaser or
Purchasers for which such arrangements have not been made; but nothing herein shall relieve a defaulting Purchaser from liability for its default. 


If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by you and the Company
as provided in Section 9(a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company
shall not exercise the right described in Section 9(b) above to require non-defaulting Purchasers to purchase Securities of a defaulting Purchaser or Purchasers, then this Agreement (or, with respect to
any Additional Closing Date, the obligations of the Purchasers to purchase and of the Company to sell the Option Securities) shall thereupon terminate, without liability on the part of any non-defaulting
Purchaser or the Company, except for the expenses to be borne by the Company and the Purchasers as provided in Section 10 hereof and the indemnity and contribution agreements in Section 6 hereof;
but nothing herein shall relieve a defaulting Purchaser from liability for its default. 
  

	10.	 Payment of Expenses. The Company covenants and agrees with the several Purchasers that the Company
will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the issue of the Securities and the shares of Common Stock issuable upon conversion of the
Securities and all other expenses in connection with the preparation, printing, reproduction and filing of the Preliminary Offering Memorandum and the Offering Memorandum and any amendments and supplements thereto and the mailing and delivering of
copies thereof to the Purchasers and dealers; (ii) the cost of printing or producing any Agreement among Purchasers, this Agreement, the Indenture, the Capped Call Confirmations, the Securities, the Blue Sky and legal investment memoranda,
closing documents (including any compilations thereof), Permitted General Solicitation Materials and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (iii) all expenses in connection with the
qualification of the Securities and the shares of Common Stock issuable upon conversion of the Securities for offering and sale under state securities laws as provided in Section 3(c) hereof, including the reasonable and
documented fees and disbursements of counsel for the Purchasers in connection with such qualification and in connection with the Blue Sky and legal investment memoranda; provided that the reasonable fees of counsel for the Purchasers relating
to subclause (iii) of this Section 10 shall not exceed $10,000, (iv) any fees charged by securities rating services for rating the Securities; (v) the cost of preparing the Securities; (vi) the fees and expenses of the Trustee
and any agent of the Trustee and the fees and disbursements of counsel for the Trustee in connection with the Indenture and the Securities; (vii) all costs and expenses incurred in connection with any “road show” presentation to
potential purchasers of the Securities; (viii) any cost incurred in connection with the listing of the shares of Common Stock issuable upon conversion of the Securities; and (ix) all other costs and expenses incident




  
 30 














	 	
to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section, including any stamp, transfer and similar taxes in connection with the original
issue and sale of the Securities to the Purchasers. It is understood, however, that, except as provided in this Section 10, and Sections 6 and 13 hereof, the Purchasers will pay all of their
own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Securities by them, and any advertising expenses connected with any offers they may make. 


 

	11.	 Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Purchaser referred to in Section 6 hereof. Nothing in this Agreement is intended
or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Purchaser shall be deemed to be a successor
merely by reason of such purchase. 


  

	12.	 Survival. The respective indemnities, rights of contribution, representations, warranties and agreements
of the Company and the several Purchasers contained in this Agreement or made by or on behalf of the Company or the several Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment
for the Securities and shall remain in full force and effect, regardless termination of this Agreement or any investigations made by or on behalf of the Company or the several Purchasers or the directors, officers, controlling persons or affiliates
referred to in Section 6 hereof. 


  

	13.	 Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly
provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are required to be closed in New York City; and
(c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act. 


  

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


  

	15.	 Miscellaneous. 



 

	 	(a)	 Notices. All statements, requests, notices, agreements and other communications hereunder shall be in
writing and shall be deemed to have been duly given if mailed or transmitted and confirmed by any standard form of telecommunication. Notices to the Purchasers shall be delivered or sent by mail or facsimile transmission to the Representatives in
care of Goldman Sachs & Co. LLC, 200 West Street, New York, New York 10282-2198, Attention: Registration Department and J.P. Morgan Securities LLC, 383 Madison Avenue, New York, New York 10179 (fax: 917-456- 3534); and if to the Company
shall be delivered or sent by mail or facsimile transmission to the address of the Company set forth in the Offering Memorandum, Attention: Secretary. 



  
 31 














	 	(b)	 Governing Law. This Agreement and any claim, controversy or dispute arising under or related to this
Agreement 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 any law other than the laws of the State of New York. 



 

	 	(c)	 Submission to Jurisdiction. The Company agrees that any suit or proceeding arising in respect of this
agreement or our engagement 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 the
Company agrees to submit to the jurisdiction of, and to venue in, such courts. 


  

	 	(d)	 Waiver of Jury Trial. The Company and each of the Purchasers 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. 



 

	 	(e)	 Recognition of the U.S. Special Resolution Regimes. 



 

	 	(i)	 In the event that any Purchaser that is a Covered Entity becomes subject to a proceeding under a U.S. Special
Resolution Regime, the transfer from such Purchaser of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if
this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States. 


  

	 	(ii)	 In the event that any Purchaser that is a Covered Entity or a BHC Act Affiliate of such Purchaser becomes
subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Purchaser are permitted to be exercised to no greater extent than such Default Rights could be exercised under the
U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States. 



As used in this section: 

“BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12
U.S.C. § 1841(k).

any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including any electronic signature
covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall
be deemed to have been duly and validly delivered and be valid and effective for all purposes. 


  

	 	(g)	 Amendments or Waivers. No amendment or waiver of any provision of this Agreement, nor any consent or
approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

	 	(k)	 Entire Agreement. This Agreement constitutes the entire agreement of the parties to this Agreement and
supersedes all prior agreements and understandings (whether written or oral) between the Company and the Purchasers, or any of them, with respect to the subject matter hereof. 



  
 33 














	 	(l)	 Liability. If this Agreement shall be terminated pursuant to Section 7 hereof,
the Company shall not then be under any liability to any Purchaser except as provided in Sections 10 and 6 hereof; but, if for any other reason (other than solely because of the termination of this Agreement
pursuant to Section 9), the Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Purchasers through you for all expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the Purchasers in making preparations for the purchase, sale and delivery of the Securities, but the Company shall then be under no further liability to any Purchaser except as provided in
Sections 10 and 6 hereof. 


  

	 	(m)	 Tax Treatment. Notwithstanding anything herein to the contrary, the Company (and the Company’s
employees, representatives and other agents) are authorized to disclose to any and all persons, the tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided

“Eligible Green Projects” (as defined in “Use of Proceeds” in the Preliminary Offering Memorandum).
		
	Increase in Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change or a Notice of Redemption:	  	If the “effective date” of a “make-whole fundamental change” (each as defined in the Preliminary Offering Memorandum) occurs prior to the maturity date of the Notes or if the Issuer delivers a notice of
redemption with respect to any or all of the Notes, the Issuer will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Notes in connection with such a make-whole fundamental change or notice of redemption,
as the case may be, as described under “Description of Notes—Conversion Rights— Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or Notice of Redemption” in the Preliminary Offering
Memorandum.
		
		  	The following table sets forth the number of additional shares by which the conversion rate will be increased per $1,000 principal amount of Notes for conversions in connection with a make-whole fundamental change or notice of

 The exact stock prices and effective dates may not be set forth in the table above, in which case: 

 

	 	•	 	 If the stock price is between two stock prices in the table above or the effective date is between two effective
dates in the table above, the number of additional shares by which the conversion rate for the Notes will be increased will be determined by a straight-line interpolation between the number of additional shares set forth for the higher and lower
stock prices and the earlier and later effective dates, as applicable, based on a 365-day year. 


  

	 	•	 	 If the stock price is greater than $175.00 per share (subject to adjustment in the same manner as the stock
prices set forth in the column headings of the table above as described in the Preliminary Offering Memorandum), no additional shares will be added to the conversion rate for the Notes. 



 

	 	•	 	 If the stock price is less than $26.60 per share (subject to adjustment in the same manner as the stock prices
set forth in the column headings of the table above as described in the Preliminary Offering Memorandum), no additional shares will be added to the conversion rate for the Notes. 



  
 Schedule 4-3 













 Notwithstanding the foregoing, in no event will the conversion rate per $1,000 principal amount of Notes
exceed 37.5939 shares of common stock, subject to adjustment in the same manner as the conversion rate as set forth under “Description of Notes—Conversion Rights—Conversion Rate Adjustments” in the Preliminary Offering
Memorandum.

beneficial ownership of shares of Common Stock shall be required or shall be made voluntarily in connection with such donation, transfer or distribution (other than any required filing on a Form 5 that is made after the expiration of the close of
business 60 days after the date of the Offering Memorandum), (C) in the case of any transfer or distribution pursuant to clause (vii), (viii), (xi) and (xii) it shall be a condition to such transfer that any filing under Section 16(a) of
