	 	(a)	 Indemnification of the Purchasers by the Sunnova Entities. Each of the Sunnova Entities agrees, jointly
and severally, 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 Sunnova Entities 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 Sunnova Entities by any Purchaser through the Representative 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 Sunnova Entities by the Purchasers. Each Purchaser, severally and not jointly,
will indemnify and hold harmless each of the Sunnova Entities, its directors and officers and each person, if any, who controls any of the Sunnova Entities within the meaning of Section 15 of the Securities Act or Section

  
 23 

	 	
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 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 Sunnova
Entities by such Purchaser through the Representative 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—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.

  
 24 

	 	
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 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 Representative and any such separate firm for the Sunnova Entities, their directors, their officers and any control persons of any of the Sunnova Entities 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 

  
 25 

	 	
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 Sunnova Entities 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 Sunnova Entities 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, as well as any other relevant equitable considerations. The relative benefits received by the Sunnova Entities 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 Sunnova Entities 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 Sunnova Entities 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 Sunnova
Entities 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 as set forth on Schedule 1 hereto, and not joint. 

 

	 	(e)	 Limitation on Liability. The Sunnova Entities and the Purchasers agree that it would not be just and
equitable if contribution pursuant to paragraph (d) 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 (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) 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 

  
 26 

	 	
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 in this Section 6(e) to contribute are several in proportion to their respective purchase obligations as set forth on Schedule 1 hereto, 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. 

 

	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 Representative, by
notice to the Company, if after the execution and delivery of this Agreement and on or prior to the 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 any of the Sunnova Entities 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 Representative, 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 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 for a period of not more than seven days, 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. 

  
 27 

	 	(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 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 shall thereupon terminate, without liability on the part of any non-defaulting Purchaser or the Sunnova Entities, except for the expenses to be borne by the Sunnova Entities 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. Each of the Sunnova Entities covenants and agrees, jointly and severally, with the
several Purchasers that the Sunnova Entities will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Sunnova Entities’ counsel and accountants in connection with the issue of the Securities and all other
expenses in connection with the preparation, printing, reproduction, distribution (including any form of electronic distribution) 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 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 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 

  
 28 

	 	
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; and (viii) all other costs and
expenses incident 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 15 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 Sunnova Entities and the several Purchasers contained in this Agreement or made by or on behalf of the Sunnova Entities 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 Sunnova Entities 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 and (b) the term “business day” means any day other than a day on which banks are required to be
closed in New York City. 

  

	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 Sunnova Entities, 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 

  
 29 

	 	
to the Purchasers shall be delivered or sent by mail or facsimile transmission to the Representative in care of BofA Securities, Inc., 1540 Broadway, 26th Floor, New York, New York 10036,
Attention: High Yield Legal Department (fax: 212-901-7897); and if to any of the Sunnova Entities shall be delivered or sent by mail or facsimile transmission to
the address of the Company set forth in the Offering Memorandum, Attention: Secretary. 

  

	 	(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. Each of the Sunnova Entities 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 each of the Sunnova Entities agrees to submit to the jurisdiction of, and to venue in, such courts. 

  

	 	(d)	 Waiver of Jury Trial. Each of the Sunnova Entities and each of the Purchasers hereby irrevocably waive,
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:

47.3(b); or 

  

	 	(3)	 a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. §

	 	(f)	 Counterparts. This Agreement may be signed in counterparts (which may include counterparts delivered by
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) 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.

representative. 

  

	 	(j)	 Time is of the Essence. Time shall be of the essence of this Agreement. 

  
 31 

	 	(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 Sunnova Entities and the Purchasers, or any of them, with respect to the subject matter hereof. 

 

	 	(l)	 Liability. If this Agreement shall be terminated pursuant to Section 8 hereof,
the Sunnova Entities 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 Sunnova Entities as provided herein, the Sunnova Entities will reimburse the Purchasers through the Representative for all expenses approved in
writing by the Representative, 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 Sunnova Entities 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 Sunnova Entities (and the Sunnova
Entities’ 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 to the Sunnova Entities relating to that treatment and structure, without the Purchasers’ imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential

otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to the second business day before delivery will be required, by virtue of the fact that the notes initially will settle in T+5, to specify an alternative settlement
cycle at the time of any such trade to prevent failed settlement. Purchasers of the notes who wish to trade the notes prior to their date of delivery hereunder should consult their own advisors.

 ANNEX I 

Form of Opinion of Counsel for the Sunnova Entities 
  

	 	(i)	 The Company is a corporation validly existing and in good standing under the Delaware General Corporation Law,
with all requisite corporate power and authority to own, lease and operate its properties and conduct its business in all material respects as described in the Pricing Disclosure Package and the Offering Memorandum. 

 

	 	(ii)	 The Parent Guarantor is a corporation validly existing and in good standing under the Delaware General

company validly existing and in good standing under the Delaware Limited Liability Company Act, with all requisite limited liability company power and authority to own, lease and operate its properties and conduct its business in all material

	 	(iv)	 Each of the Company, the Parent Guarantor and Intermediate Holdco is duly qualified to transact business as a
foreign corporation in the jurisdictions set forth opposite its name on Schedule 1 thereto. 

  

	 	(v)	 Each of the Company, the Parent Guarantor and Intermediate Holdco has all requisite corporate or limited
liability company power, and authority to execute and deliver the Purchase Agreement and the Indenture and to perform its obligations thereunder. 

  

	 	(vi)	 The Purchase Agreement has been duly authorized, executed and delivered by each of the Company, the Parent
Guarantor and Intermediate Holdco. 

  

	 	(vii)	 The Indenture has been duly authorized, executed and delivered by the Sunnova Entities, and assuming the due
authorization, execution and delivery thereof by the Trustee, constitutes a valid and legally binding obligation of the Sunnova Entities, enforceable against the Sunnova Entities in accordance with its terms. 

 

	 	(viii)	 The Securities have been duly authorized by the Sunnova Entities, and when duly executed by the Sunnova
Entities and authenticated by the Trustee in the manner provided in the Indenture (assuming due authorization, execution and delivery of the Indenture by the Trustee) and delivered to and paid for by the Initial Purchasers in accordance with the
terms of the Purchase Agreement constitute valid and legally binding obligations of the Sunnova Entities, enforceable against the Sunnova Entities in accordance with their respective terms. 

 

	 	(ix)	 The execution and delivery by the Sunnova Entities of the Purchase Agreement and the Indenture, and the
consummation of the transactions therein contemplated, 

  
 Annex I-1 

	 	
including the issuance and sale of the Securities, do not (i) violate the charter or bylaws or similar organizational documents of the Sunnova Entities, (ii) result in a breach or
violation of any of the terms or provisions of, or constitute a default (or an event that, with notice or lapse of time or both, would constitute such a default) under, or result in the creation or imposition of any lien, charge or encumbrance upon
any property of the Sunnova Entities or any Material Subsidiary pursuant to the express terms of, any Specified Agreement or (iii) violate any Applicable Laws of the United States or the State of New York, the Delaware General Corporation Law
or the Delaware Limited Liability Company Act, except, in the case of clauses (ii) and (iii) above, for any such conflict, breach, violation, default, lien, charge or encumbrance that would not, individually or in the aggregate, have a Material
Adverse Effect; provided, however, that such counsel expresses no opinion with respect to federal or state securities laws or other anti-fraud statutes, rules or regulations. 

 

	 	(x)	 No consent, approval, authorization, order, registration, filing or qualification of or with any governmental
authority is required under the Applicable Laws of the United States and the State of New York, the Delaware Limited Liability Company Act or the Delaware General Corporation Law in connection with the execution and delivery of the Purchase
Agreement and the Indenture by the Sunnova Entities, the performance by each of the Sunnova Entities of its obligations thereunder, including the issuance and sale of the Securities and the consummation of the transactions provided for therein,
except such consents, approvals, authorizations, orders, registrations, filings or qualifications which may be required under applicable state or federal securities laws, as to which such counsel does not express any opinion, and those which have
already been made or obtained. 

  

	 	(xi)	 The statements set forth in the Pricing Disclosure Package and the Offering Memorandum under the captions
“Description of Notes” insofar as the statements purport to constitute a summary of the terms of the Securities, are accurate summaries in all material respects. 

 

	 	(xii)	 The statements set forth in the Pricing Disclosure Package and the Offering Memorandum under the caption
“Certain U.S. Federal Income Tax Considerations,” insofar as they purport to constitute a summary of laws or regulations, are accurate summaries of such laws or regulations in all material respects. 

 

	 	(xiii)	 None of the Sunnova Entities is, and immediately following the sale of the Securities to be issued and sold by
the Company pursuant to the Purchase Agreement and the application of the net proceeds by the Company from such sale as described in the Pricing Disclosure Package and the Offering Memorandum under the caption “Use of Proceeds,” will not
be required to register as an “investment company,” as such term is defined in the Investment Company Act. 

  

	 	(xiv)	 Assuming without independent investigation, (a) that the Securities are sold to the Purchasers, and
initially resold by the Purchasers, in accordance with the terms of and in the manner contemplated by, the Purchase Agreement and the Offering Memorandum; (b) the accuracy of the representations and warranties of the Sunnova

  
 Annex I-2 

	 	
Entities set forth in the Purchase Agreement and in those certain certificates delivered pursuant thereto on the date hereof; (c) the accuracy of the representations and warranties of the
Purchasers set forth in the Purchase Agreement; (d) the due performance and compliance by the Sunnova Entities and the Purchasers of their respective covenants and agreements set forth in the Purchase Agreement; and (e) the
Purchasers’ and the Sunnova Entities’ compliance with the Offering Memorandum and the transfer procedures and restrictions described therein, it is not necessary to register the issuance and sale of the Securities by the Issuer to the
Purchasers or the initial offer and resale of the Securities by the Purchasers, in each case in the manner contemplated by the Purchase Agreement and the Offering Memorandum, under the Securities Act, or to qualify the Indenture in respect thereof
under the United States Trust Indenture Act of 1939, it being expressly understood that we express no opinion in this paragraph (xiv) as to any subsequent offer or resale of any of the Securities. 

As used in this opinion letter, “Applicable Laws” means those laws, rules and regulations that, in such counsel’s
experience, are normally applicable to transactions of the type contemplated by the Purchase Agreement, without such counsel having made any special investigation as to the applicability of any specific law, rule or regulation, provided,
however, that such references do not include any municipal or other local laws, rules or regulations, any Federal or state securities laws or regulations, any other antifraud laws, any fraudulent transfer laws, or any environmental, labor,
tax, insurance or antitrust, laws, rules or regulations. 
 The opinions set forth in paragraphs (vii) and (viii) are subject to the
qualification that the enforcement of the agreements and instruments referred to therein may be limited by (a) applicable bankruptcy, insolvency, reorganization, arrangement, fraudulent conveyance or transfer, preference, moratorium,
conservatorship or similar laws of general applicability relating to or affecting creditors’ rights and remedies generally and to general principles of equity (whether considered in a proceeding in equity or at law) and comity, including,
without limitation, the possible unavailability of specific performance, injunctive relief or any other equitable remedy, (b) principles of materiality and reasonableness and implied covenants of good faith and fair dealing, (c) possible
judicial action giving effect to governmental actions or foreign laws affecting creditors’ rights and (d) public policy, applicable law relating to fiduciary duties and indemnification and contribution. 

Such opinion in paragraph (ix) above is limited in that such counsel expresses no opinion with respect to any breach of, or default
under, or the creation of any lien or security interest under, any Specified Agreement (i) not readily ascertainable from the face of any such Specified Agreement, (ii) arising under or based on any cross-default provision insofar as it
relates to a default under an agreement that is not a Specified Agreement or (iii) arising under or based on any covenant of a financial or numerical nature or requiring computation. 

In rendering such opinion, such counsel may (i) rely in respect of matters of fact upon the representations and warranties of the parties
to the Purchase Agreement, upon certificates of officers and employees of the Company and upon information obtained from public officials, (ii) assume that all documents submitted to us as originals are authentic, that all copies submitted to
us conform to the originals thereof, and that the signatures on all documents examined by us are genuine, (iii) state that such counsel’s opinion is limited to matters governed by the law of the State of New York, the

  
 Annex I-3 

 
Delaware General Corporation Law, the Delaware Limited Liability Company Act and United States federal law to the extent specifically referred to herein, in each case as published and in effect
on the date hereof and (iv) with respect to the opinions expressed as to the valid existence and good standing or due qualification as a foreign corporation or limited liability company, as the case may be, of the Sunnova Entities and the
Material Subsidiaries, state that such opinions are based solely upon certificates of good standing provided by the Secretary of State of the state of formation and certificates of foreign qualification provided by the Secretary of State of the
states listed on a schedule 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 Closing Date and shall be provided to counsel to the Purchasers). 

Such counsel reviewed the Pricing Disclosure Package and the Offering Memorandum and have participated in conferences with officers and other
representatives of the Company, with representatives of the Company’s independent registered public accounting firm, and with your representatives and your counsel, at which the contents of the Pricing Disclosure Package, the Offering
Memorandum and related matters were discussed. The purpose of such counsel’s professional engagement was not to establish or confirm factual matters set forth in the Pricing Disclosure Package or the Offering Memorandum, and such counsel has
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 Pricing Disclosure Package and the Offering Memorandum involve matters of a non-legal nature. Accordingly, such counsel is not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements included in the Pricing Disclosure Package and the
Offering Memorandum (except to the extent stated in paragraphs (xi) and (xii) above). Subject to the foregoing and on the basis of the information such counsel gained in the course of performing the services referred to above, such counsel
advises you that nothing came to such counsel’s attention that caused us to believe that: 
 (1) 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 
 (2) the Offering Memorandum, 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 such counsel 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 included or incorporated by reference therein or omitted therefrom, or (b) the representations and warranties and other statements of fact contained in the exhibits
to the documents incorporated by reference therein. 
 The opinion of Baker Botts L.L.P. described above shall be rendered to the Purchasers
at the request of the Company and shall so state therein. The opinion is being furnished only to you as representative of the Purchasers solely for your benefit and the benefit of the several Purchasers in connection with the offer and sale of the
Securities pursuant to the Purchase Agreement. The opinion may not be relied upon by any other person (including by any person that acquires the 

  
 Annex I-4 

 
Securities from the several Purchasers) or for any other purpose. No other use, circulation, quotation or distribution of the opinion may be made. The opinion speaks as of the date thereof, and
such counsel does not undertake and hereby disclaims any obligation to update the opinion.

	 	6.	 Confidentiality 

 

	 	6.1	 Definition of Confidential Information. 

“Confidential Information” refers to an item of information, or a compilation of information, in any form (tangible or intangible),
related to the Company’s business that the Company has not made public or authorized public disclosure of, and that is not through proper means readily available to persons outside the Company who are under no obligation to keep it
confidential. Confidential Information will not lose its protected status under this Agreement if it becomes known to other persons through improper means such as the unauthorized use or disclosure of the information by Executive or another person.
Confidential Information includes, but is not limited to: (i) information related to the Company’s methods of operations, financial information, strategic planning, operations budgets and strategies, payroll data, management systems,
programs, computer systems, marketing plans and strategies, and merger and acquisition strategies; (ii) the Company’s business plans and analysis, customer and prospect lists, research and development data, buying practices, methods,
techniques, technical data, know-how, innovations, unpatented inventions, and trade secrets; and (iii) information about the business affairs of third parties (including, but not limited to, clients and

  
 7 

 
acquisition targets) that such third parties provide to the Company in confidence. Confidential Information will include trade secrets, but an item of Confidential Information need not qualify as
a trade secret to be protected by this Agreement. the Company’s confidential exchange of information with a third party for business purposes will not remove it from protection under this Agreement. The presence of non-confidential items of information within an otherwise confidential compilation of information will not remove the compilation itself from the protection of this Agreement. Executive acknowledges that items of
Confidential Information are the Company’s valuable assets and have economic value, actual or potential, because they are not generally known by the public or others who could use them to their own economic benefit and/or to the competitive
disadvantage of the Company, and thus, should be treated as the Company’s trade secrets. 
  

	 	6.2	 Unauthorized Use or Disclosure. 

Executive agrees to hold the Company’s Confidential Information in confidence and trust, and not to engage in any unauthorized use or
disclosure of such information for so long thereafter as such information qualifies as Confidential Information. If disclosure is compelled by law, Executive will give the Company as much written notice as possible under the circumstances, will
refrain from use or disclosure for as long as the law allows, and will cooperate with the Company to protect such information, including taking every reasonable step to protect against unnecessary disclosure. Executive agrees that if he becomes
aware of an unauthorized use or disclosure of the Company’s Confidential Information, he will immediately notify TaskUss Legal Department. Nothing contained in this Agreement precludes Executive, or any individual, from communicating with any
government agency, including the Securities & Exchange Commission (SEC). This Agreement is intended to supplement and not supersede Executive’s Confidentiality and Inventions Assignment Agreement with the Company. 

 

	 	6.3	 Third Party Confidential Information. 

Executive recognizes that TaskUs has received and in the future will receive from third parties their confidential or proprietary information
(“Third Party Confidential Information”) subject to a duty on TaskUs’ behalf to maintain the confidentiality of such information and to use it only for certain limited purposes. Executive agrees to hold each such Third Party
Confidential Information in the strictest confidence and not to disclose it to any person, firm, corporation, or entity in whatever form, or to use it except as necessary in carrying out work for TaskUs consistent with the Company’s agreement
with any such third party.

	 	7.	 Post-Employment Restrictions. 

 

	 	7.1	 Definitions. 

  

	 	(a)	 “Look Back Period” shall mean the final two years of employment. References to the end of
Executive’s employment or termination of employment in this Agreement refer to the end of employment, regardless of which party terminates the relationship or the reason(s) for such termination. 

 

	 	(b)	 “Restricted Area” shall mean the territory or territories that Executive was assigned, had
responsibilities or duties for, or called on Covered Customers (defined below) within the Look Back Period. If this definition is inapplicable, then “Restricted Area” refers to the United States and each additional country where the
Company does business. 

  

	 	(c)	 “Solicit” and related terms such as “Soliciting” shall mean to knowingly engage in
acts or communications, in person or through others, that are intended to cause, or can reasonably be expected to induce or encourage, a particular responsive action (such as buying a good or service or hiring), regardless of which party first
initiates the communication or whether the communication is response to an inquiry or not. 

  

	 	(d)	 “Covered Client” shall mean an established client of the Company (person or entity) as to
which Executive had business-related contact or dealings or received Confidential Information about during Executive’s employment with the Company. A client will be presumed to be established where actual sales and/or services have occurred or
been performed, there is an active proposal for sales or services pending, or sales or services were being negotiated during the Look Back Period. 

  

	 	(e)	 “Conflicting Product or Service” shall mean a product and/or service provided by a person or
entity other than TaskUs that would replace or compete with a TaskUs product or service (existing or under development) that Executive had material involvement with or was provided Confidential Information about during Executive’s employment
with the Company. By way of example, the products and services the Company provides to its clients that Executive is involved in may include but are not limited to content moderation services, digital customer experience services, artificial
intelligence operations services, trust and safety services, including anti-money laundering and KYC services, other digital business process outsourcing services, and the provision of information technology or information services to the extent
necessary to provide the foregoing. For the sake of clarity, a Conflicting Products or Service is a product or service actually offered or provided by TaskUs to its clients or one that it has plans to offer or provide during Executive’s
employment with the Company. Conflicting Products or Services do not include a product or service of TaskUs if TaskUs is no longer in the business of providing such product or service to its customers at the relevant time of enforcement.

  

	 	(f)	 “Competing Activities” shall mean any activities or services undertaken on behalf of a
competitor (which is understood to mean any person or entity engaged in the business of providing a Conflicting Product or Service) that are: (i) the same or similar in function or purpose to those Executive performed for the Company during the
Look Back Period, or (ii) otherwise likely to result in the use or disclosure of Confidential Information. Competing Activities are understood to exclude: activities on behalf of an independently operated subsidiary, division, or unit of a
diversified corporation or similar business that has common ownership with a competitor so long as the independently operated business unit does not involve a Conflicting Product or Service; and, a passive and
non-controlling ownership interest in a competitor through ownership of less than 2% of the stock in a publicly traded company. 

  
 9 

	 	7.2	 Restriction on Unfair Competition.  

Executive agrees that during Executive’s employment with the Company and for a period of one year thereafter, Executive will not
participate in, supervise, or manage (as an employee, consultant, contractor, officer, owner, director, or otherwise) Competing Activities in the Restricted Area. The Parties agree this restriction is necessary to protect trade secrets, Confidential
Information, goodwill, and other legitimate business interests of the Company. 
  

	 	7.3	 Restriction on Interfering with Employee Relationships. 

Executive agrees that during Executive’s employment with the Company and for a period of two (2) years thereafter, Executive will not
Solicit any employee of the Company that Executive has knowledge of through employment with the Company to terminate his or her employment with the Company. The restriction in this Section is necessary to protect Confidential Information, workforce
stability, and other legitimate business interests, and to prevent unfair competition. Nothing herein is intended to be construed as a prohibition against general advertising such as “help wanted” ads that are not targeted at TaskUs’
employees. The Parties agree this restriction is inherently reasonable in geography because it is limited to the places or locations where the employees that Executive has knowledge of are located; however, if an additional geographic limitation is
needed in order for the foregoing restriction to be enforceable, then it shall be considered limited to the Restricted Area. In the event TaskUs loses an employee due, in whole or in part, to conduct by Executive that violates this Agreement prior
to the issuance of injunctive relief, Executive shall pay the Company a sum equal to thirty percent (30%) of the annual wages of the person(s) who were improperly solicited and left TaskUs, based on such person’s last rate of pay with TaskUs.
This payment shall not preclude or act as a substitute for any remedy that would otherwise be available, including but not limited to, injunctive relief to prevent further violations. 

 

	 	7.4	 Restriction on Interfering with Customer Relationships. 

Executive agrees that during Executive’s employment with the Company and for a period of two (2) years thereafter, Executive will not
directly or indirectly, Solicit a Covered Client to (i) cease or reduce doing business with TaskUs or (ii) purchase a Conflicting Product or Service. Executive understands and agrees that this restriction is necessary to protect trade
secrets, Confidential Information, goodwill, and other legitimate business interests of the Company. The parties agree this restriction is inherently reasonable in geography because it is limited to the places or locations where the Covered Customer
is doing business at the time; however, if an additional geographic limitation is needed in order for the foregoing restriction to be enforceable, then it shall be considered limited to the Restricted Area. 

 

	 	7.5	 Reasonableness of Covenants. 

Executive acknowledges and agrees that the covenants in this Agreement are reasonable and valid in geographical and temporal scope and in all
other respects. 
  

	 	7.6	 Tolling. 

If Executive violates one of the restrictions in this Agreement that contains a time limitation, the time period for the restriction at issue
shall be extended by one day for each day Executive remains in violation of the restriction; provided, however, that this extension of time shall be capped so that once Executive has complied with the restriction for the originally proscribed length
of time it shall expire. 
  

	 	8.	 Notice 

Before accepting new employment, Executive will advise any such future employer of the restrictions in this Agreement. Executive agrees
that the Company may advise any such future employer or prospective employer of this Agreement and its position on the potential application of this Agreement without such giving rise to any legal claim. 

  
 10 

	 	9.	 Remedies for Breach.  

If Executive breaches or threatens to breach any of the provisions of this Agreement, the Company shall have the following rights and remedies,
in addition to any others, each of which shall be independent of the other and severally enforceable: 
  

	 	9.1	 The right to an injunction restraining such breach or threatened breach and to have the provisions of this
Agreement specifically enforced by a court of competent jurisdiction, it being acknowledged and agreed that any such breach or threatened breach will cause irreparable injury to the Company and that money damages will not provide an adequate remedy,
and that no bond or other security shall be required in obtaining such equitable relief, provided however, that if the posting of a bond is required by law for injunctive relief to issue then a bond of $1,000 shall be deemed a reasonable bond; and

  

	 	9.2	 The right and remedy to require Executive to account for and repay to the Company the severance described in
Section 4.3 above, if any. 

  

	 	9.3	 In accordance with the terms of the Omnibus Plan, the right to cancel any of the Executive’s outstanding
awards or provide for forfeiture and repayment to the Company on any gain realized on the vesting or exercise of any awards previously granted to Executive. 

  

	 	9.4	 Survival. The post-employment restrictions provided for in this Agreement shall survive the
termination of Executive’s employment with the Company regardless of the cause of the termination. All of the restrictive covenants in this Agreement shall be construed as independent agreements; and, the existence of any claim or cause of
action against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of any of Executive’s obligations under this Agreement. If a court determines that a restriction
provided for herein cannot be enforced as written due to over breadth (such as time, scope of activity, or geography) within the relevant jurisdiction, the court will (for purposes of that jurisdiction) enforce the restrictions to such lesser extent
as is allowed by law and/or reform the restriction where such is necessary to make it enforceable to protect the Company’s legitimate business interests. If, despite the foregoing, any provision contained in this Agreement is determined to be
void, illegal or unenforceable, in whole or in part, then the other provisions contained herein shall remain in full force and effect as if the provision that was determined to be void, illegal, or unenforceable had not been contained herein. Any
waiver by the Company of a breach of any provision of this Agreement shall not operate or be construed as waiver of any subsequent breach hereof. 

  

	 	10.	 Arbitration. 

Any dispute, controversy, or claim arising out of or related to the Executive’s employment by the Company, or termination of employment,
including but not limited to claims arising under or related to this Agreement or any breach of this Agreement, and any alleged violation of federal, state, or local statute, regulation, common law, or public policy, shall be submitted to and
decided by binding arbitration in accordance with the Alternative Dispute Resolution & Mutual Arbitration Agreement between the Parties (the “Arbitration Agreement”). The Arbitration Agreement is incorporated herein by reference.

  

	 	11.	 Governing Law, Jurisdiction, and Venue. This Agreement, for all purposes, shall be construed in
accordance with the laws of Texas without regard to conflicts of law principles. 

  
 11 

	 	12.	 Entire Agreement. Unless specifically provided herein, this Agreement, together with the Arbitration
Agreement and any confidentiality agreement between the Executive and the Company, contains all of the understandings and representations between the Executive and the Company pertaining to the subject matter hereof and supersedes all prior and
contemporaneous understandings, agreements, representations and warranties, both written and oral, with respect to such subject matter. 

  

	 	13.	 Modification and Waiver. No provision of this Agreement may be amended or modified unless such amendment
or modification is agreed to in writing and signed by the Executive and by the Chief Executive Officer of the Company. No waiver by either of the parties of any breach by the other party hereto of any condition or provision of this Agreement to be
performed by the other party hereto shall be deemed a waiver of any similar or dissimilar provision or condition at the same or any prior or subsequent time. 

 

	 	14.	 Severability. Should any provisions of this Agreement be held to be invalid, illegal, or unenforceable
in any respect, such invalidity, illegality, or unenforceability shall not affect any other provisions hereof, and if such provision or provisions are not modified as provided above, this Agreement shall be construed as if such invalid, illegal, or
unenforceable provisions had not been set forth herein. 

  

	 	15.	 Captions. Captions and headings of the sections and paragraphs of this Agreement are intended solely for
convenience and no provision of this Agreement is to be construed by reference to the caption or heading of any section or paragraph. 

  

	 	16.	 Counterparts. This Agreement may be executed in separate counterparts, each of which shall be deemed an
original, but all of which taken together shall constitute one and the same instrument. 

  

	 	17.	 Section 409A. 

 

	 	17.1	 General Compliance. 

This Agreement is intended to comply with Section 409A or an exemption thereunder and shall be construed and administered in accordance
with such intent. Notwithstanding any other provision of this Agreement, payments provided under this Agreement may only be made upon an event and in a manner that complies with Section 409A or an applicable exemption. Any nonqualified deferred
compensation payments under this Agreement that may be excluded from Section 409A either as separation pay due to an involuntary separation from service or as a short-term deferral shall be excluded from Section 409A to the maximum extent
possible. For purposes of Section 409A, each installment payment provided under this Agreement shall be treated as a separate payment. Any payments to be made under this Agreement upon a termination of employment shall only be made upon a
“separation from service” under Section 409A. Notwithstanding the foregoing, the Company makes no representations that the payments and benefits provided under this Agreement comply with Section 409A, and in no event shall the
Company be liable for all or any portion of any taxes, penalties, interest, or other expenses that may be incurred by the Executive on account of non-compliance with Section 409A. 

Specified Employees. Notwithstanding any other provision of this Agreement, if any payment or benefit provided to the Executive in
connection with his termination of employment is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A and the Executive is determined to be a “specified employee” as defined in
Section 409A(a)(2)(b)(i), then such payment or benefit shall not be paid until the first payroll date to occur following the six-month anniversary of the date of the Executive’s termination or, if
earlier, on the Executive’s death (the “Specified Employee Payment Date”). The aggregate of any payments that would otherwise have been paid before the Specified Employee Payment Date [and interest on such amounts calculated
based on the applicable federal rate published by the Internal Revenue Service for the month in which the Executive’s separation from service occurs] shall be paid to the Executive in a lump sum on the Specified Employee Payment Date and
thereafter, any remaining payments shall be paid without delay in accordance with their original schedule. 

  
 12 

	 	17.2	 Reimbursements. To the extent required by Section 409A, each reimbursement or in-kind benefit provided under this Agreement shall be provided in accordance with the following: 

  

	 	(a)	 the amount of expenses eligible for reimbursement, or in-kind benefits
provided, during each calendar year cannot affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year; 

 

	 	(b)	 any reimbursement of an eligible expense shall be paid to the Executive on or before the last day of the
calendar year following the calendar year in which the expense was incurred; and 

  

	 	(c)	 any right to reimbursements or in-kind benefits under this Agreement
shall not be subject to liquidation or exchange for another benefit. 

  

	 	18.	 Successors and Assigns. This Agreement is personal to the Executive and shall not be assigned by the
Executive. Any purported assignment by the Executive shall be null and void from the initial date of the purported assignment. The Company may assign this Agreement to any successor or assign (whether direct or indirect, by purchase, merger,
consolidation, or otherwise) to all or substantially all of the business or assets of the Company. This Agreement shall inure to the benefit of the Company and permitted successors and assigns.
