 2.    Registration Rights. The Company covenants and agrees as follows:

2.2    Company Offering. 

(a)    If the Company proposes to offer (including, for this purpose, a registration effected by the Company for
shareholders other than the Holders) any of its shares of Common Stock under the Securities Act in connection with the public offering of such securities (including an “at-the market offering,” a
“bought deal” or a “registered direct offering”) solely for cash (other than in an Excluded Registration), the Company shall, at such time, promptly give each Holder notice of such offering (a “Company
Offering”). Such notice shall specify, as applicable, the amount of Common Stock to be registered, the proposed filing date of the registration statement or applicable prospectus supplement and the proposed minimum offering price of the
Common Stock, in each case to the extent then known. In the case of an offering under a shelf registration statement previously filed or to be filed by the Company pursuant to Rule 415 under the Securities Act, including where the Company qualifies
as a WKSI, such notice shall be sent as promptly as reasonably practicable and in any event no later than ten (10) days prior to the expected date of filing of such registration statement or commencement of marketing efforts for such offering
(and no later than five (5) days prior in the case of a “bought deal,” a “registered direct offering” or an “overnight transaction” where no preliminary prospectus is used). In the case of a Company Offering under
a registration statement to be filed that is not a shelf registration statement, such notice shall be sent as promptly as reasonably practicable and in any event no later than ten (10) days prior to the expected date of filing of such
registration statement. Upon the written request of each Holder given within five (5) Business Days after such notice is given by the Company (except that each Holder shall have two (2) Business Days after the Company gives such notice to
request inclusion of Registrable Securities in the Company Offering in the case of a “bought deal,” a “registered direct offering” or an “overnight transaction” where no preliminary prospectus is used), the Company
shall, subject to the provisions of Subsection 2.3, as promptly as reasonably practicable cause to be registered or include in the prospectus supplement, as applicable, all of the Registrable Securities that each such Holder has requested to
be included in such registration. The Company shall have the right to terminate or withdraw any offering initiated by it under this Subsection 2.2 before the effective date of such offering, whether or not any Holder has elected to include
Registrable Securities in such offering. The expenses (other than Selling Expenses) of such withdrawn offering shall be borne by the Company in accordance with Subsection 2.6. 

(b)    [Reserved]. 

(c)    Each Holder shall be permitted to withdraw all or part of its Registrable Securities in an offering under this
Subsection 2.2 by giving written notice to the Company of its request to withdraw; provided, that (i) such request must be made in writing prior to the effectiveness of such Registration Statement or, in the case of a public
offering, at least five (5) Business Days prior to the earlier of the anticipated filing of the “red herring” Prospectus, if applicable, and the anticipated pricing or trade date and (ii) such withdrawal shall be irrevocable and,
after making such withdrawal, the Holder shall no longer have any right to include Registrable Securities in such offering as to which such withdrawal was made. 

  
 4 

 2.3    Underwriting Requirements. 

(a)    If the Company Offering under which the Holders are entitled to registration rights pursuant to Subsection
2.2(a) hereof is a registration effected by the Company for shareholders pursuant to Subsection 2.1 of the Existing Registration Rights Agreement and the Initiating Holders (as defined in the Existing Registration Rights Agreement) intend to
distribute the securities covered by their request by means of an underwriting, the Company shall include such information in its notice to the shareholders under Subsection 2.2(a). In such event, the right of any Holder to include such
Holder’s Registrable Securities in such registration pursuant to Subsection 2.2(a) shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the
underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in Subsection 2.4(e)) enter into an underwriting agreement in customary
form with the underwriter(s) selected for such underwriting and any other participating shareholders, as appropriate. Notwithstanding any other provision of this Subsection 2.3, if the managing underwriter(s) advise(s) the Initiating Holders
in writing that marketing factors require a limitation on the number of shares or units (as applicable) to be underwritten, then the number of securities or Registrable Securities that may be included in the underwriting shall be allocated
(a) first to the holders of securities that have registration rights under the Existing Registration Rights Agreement and the Company and (b) thereafter among the Holders and the holders of Common Stock other than Registrable Securities,
in proportion (as nearly as practicable) to the number of Registrable Securities and the number of shares of Common Stock other than Registrable Securities (on a fully-diluted, as converted basis) owned by such holders or in such other proportion as
shall mutually be agreed to by all such selling holders. 
 (b)    In connection with any offering involving an
underwriting of shares or units (as applicable) of the Company’s capital stock pursuant to Subsection 2.2(a), the Company shall not be required to include any of the Holders’ Registrable Securities in such underwriting unless the
Holders accept the terms of the underwriting as agreed upon between the Company and its underwriters, and then only in such quantity as the underwriters in their sole discretion determine will not jeopardize the success of the offering by the
Company. If the total number of securities, including Registrable Securities, requested by holders to be included in such offering pursuant to Subsection 2.2(a) exceeds the number of securities to be sold (other than by the Company) that the
underwriters in their reasonable discretion determine is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the
underwriters and the Company in their sole discretion determine will not jeopardize the success of the offering. If the underwriters determine that less than all of the securities requested to be registered can be included in such offering, then the
securities that are included in such offering shall be allocated (i) first to holders of securities that have registration rights under the Existing Registration Rights Agreement and the Company and (ii) thereafter among the Holders and
the holders of Common Stock other than Registrable Securities in proportion (as nearly as practicable to) the number of Registrable Securities and the number of shares of Common Stock other than Registrable Securities (on a fully diluted, as
converted basis) owned by such holders or in such other proportions as shall mutually be agreed to by all such selling holders. For purposes of the provision in this Subsection 2.3 concerning apportionment, for any selling Holder that is a
partnership, limited liability company, or corporation, the partners, members, retired partners, retired members, stockholders, and Affiliates of such Holder, or the estates and Immediate Family Members of any such partners, retired partners,
members, and retired members and any trusts for the benefit of any of the foregoing Persons, shall be deemed to be a single “selling Holder,” and any pro rata reduction with respect to such “selling Holder” shall be based upon
the aggregate number of Registrable Securities owned by all Persons included in such “selling Holder,” as defined in this sentence. 

(c)    [Reserved]. 

  
 5 

 (d)    In the case of any underwritten offering under Subsection
2.2, each of the Holders may, subject to any limitations on withdrawal contained herein, withdraw all or part of their request to participate in the registration pursuant Subsection 2.2 after being advised of such price, discount and
other terms and shall not be required to enter into any agreements or documentation that would require otherwise. 

2.4    Obligations of the Company. Whenever required under this Section 2 to effect the
registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible: 

(a)    prepare and file a Registration Statement with respect to such Registrable Securities and use its commercially
reasonable efforts to cause such Registration Statement to become effective, and, to keep such Registration Statement effective for a period of up to one hundred eighty (180) days or, if earlier, until the distribution contemplated in the
Registration Statement has been completed, provided, however, that (i) such one hundred eighty (180) day period shall be extended for a period of time equal to the period the Holders refrain, at the request of an underwriter
of Common Stock (or other securities) of the Company, from selling any securities included in such registration, and (ii) in the case of an automatic Registration Statement on Form S-3, where the Company
shall use its commercially reasonable efforts to keep such Registration Statement effective for three years from the date of effectiveness. 

(b)    (i) prepare and file with the SEC such amendments, including post-effective amendments, and supplements to such
Registration Statement, and the Prospectus used in connection with such Registration Statement, as may be necessary to comply with the Securities Act in order to enable the disposition of all securities covered by such Registration Statement through
the applicable periods during which the Company is obligated to maintain the effectiveness of such Registration Statement, (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement, and as so
supplemented or amended to be filed pursuant to Rule 424 promulgated by the SEC under the Securities Act; and (iii) respond to any comments received from the SEC with respect to each Registration Statement or any amendment thereto; 

(c)    to the extent practicable, at least five (5) Business Days prior to filing any registration statement or
prospectus or any amendments or supplements thereto, furnish to the holders of the Registrable Securities covered by such registration statement and their counsel, copies of all such documents proposed to be filed; 

(d)    furnish to the selling Holders such numbers of copies of the signed Registration Statement, any post-effective
amendment thereto, a Prospectus, including a preliminary Prospectus, as required by the Securities Act, any amendments or supplements thereto, any Free Writing Prospectus, and such other documents as the Holders may reasonably request in order to
facilitate their disposition of their Registrable Securities; 
 (e)    use its commercially reasonable efforts to
register and qualify the securities covered by such Registration Statement under such other securities or blue-sky laws of such jurisdictions as shall be reasonably requested by the selling Holders;
provided that the Company shall not be required to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except
as may be required by the Securities Act; 
 (f)    in the event of any underwritten public offering, (i) enter
into and perform its obligations under an underwriting agreement, in usual and customary form, with the underwriter(s) of such offering and (ii) cooperate with the holders of Registrable Securities to be included in such registration and the
managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of 

  
 6 

 
certificates (not bearing any restrictive legends other than as may be required by applicable law, by the stock transfer agent, depositary or their nominee, if applicable) representing securities
to be sold under such registration, and enable such securities to be in such denominations and registered in such names as the managing underwriter or underwriters, if any, or such holders may request; 

(g)    cooperate with each Holder and each underwriter, if any, participating in the disposition of such Registrable
Securities and their respective counsel in connection with any filings required to be made with FINRA; 
 (h)    to the
extent the Company is eligible under the relevant provisions of Rule 430B under the Securities Act, if the Company files any shelf Registration Statement, include in such shelf Registration Statement such disclosures as may be required by Rule 430B
under the Securities Act (referring to the unnamed selling security holders in a generic manner by identifying the initial offering of the securities to the Holders) in order to ensure that the Holders may be added to such shelf Registration
Statement at a later time through the filing of a Prospectus supplement rather than a post-effective amendment; 

(i)    use its commercially reasonable efforts to cause all such Registrable Securities covered by such Registration
Statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities issued by the Company are then listed; 

(j)    (i) provide a transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and
provide a CUSIP number for all such Registrable Securities, in each case, not later than the effective date of such registration and (ii) cooperate with any selling Holders to facilitate the timely preparation and delivery of book-entry
interests representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which book-entry interests shall be free of all restrictive legends indicating that the Registrable Securities are unregistered or
unqualified for resale under the Securities Act, Exchange Act or other applicable securities laws, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holder may request in writing. 

(k)    (i) promptly make available for inspection by the selling Holders, any managing underwriter(s) participating in any
disposition pursuant to such Registration Statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling Holders, all financial and other records, pertinent corporate documents, and properties of
the Company, (ii) cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant, or agent, in each case, as necessary or
advisable to verify the accuracy of the information in such Registration Statement and to conduct appropriate due diligence in connection therewith (as shall be necessary, in the opinion of such seller or underwriter’s legal counsel, to conduct
a reasonable investigation with the meaning of Section 11(b)(3) of the Securities Act), and (iii) cause appropriate officers and employees to be available, on a customary basis and upon reasonable notice, to meet with prospective investors
in presentations, meetings and road shows. 
 (l)    notify each selling Holder, promptly after the Company receives
notice thereof, of the time when such Registration Statement has been declared effective or a supplement to any Prospectus forming a part of such Registration Statement has been filed; 

(m)    after such Registration Statement becomes effective, promptly notify each selling Holder of any (i) request by
the SEC that the Company amend or supplement such Registration Statement or Prospectus or (ii) stop order or other order suspending the effectiveness of any registration statement, 

  
 7 

 
issued or threatened in writing by the SEC in connection therewith, and use its commercially reasonable efforts to prevent the entry of such stop order or to remove it or obtain withdrawal of it
as soon as practicable if entered; 
 (n)    use its commercially reasonable efforts to obtain: 

(i)    at the time of pricing of any underwritten offering (including an “at-the-market offering,” a “bought deal” or a “registered direct offering”) a “cold comfort letter” from the Company’s independent registered public accounting
firm covering such matters of the type customarily covered by “cold comfort letters” as the Holders and the underwriters reasonably request; and 

(ii)    at the time of any sale in an underwritten offering pursuant to the registration statement, a
“bring-down comfort letter,” dated as of the date of such sale, from the Company’s independent registered public accountants covering such matters of the type customarily covered by “bring-down comfort letters” as the
Holders and the underwriters reasonably request; 
 (o)    use its commercially reasonable efforts to obtain, at the
time of effectiveness of each registration or, in the case of a shelf registration, at the time of pricing, and at the time of any sale pursuant to each registration, an opinion or opinions addressed to the holders of the Registrable Securities to
be included in such registration and the underwriter or underwriters, if any, in customary form and scope from legal counsel for the Company (who may be its internal legal counsel); 

(p)    promptly notify each seller of Registrable Securities covered by such registration, upon discovery by an executive
officer of the Company that the prospectus included in such registration, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements
therein not misleading, and promptly thereafter prepare and file with the SEC and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the
purchasers or prospective purchasers of such securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances under which they are made; and 
 (q)    enter into such agreements
(including underwriting agreements in customary form) and take such other actions as the Holders shall reasonably request in order to expedite or facilitate the disposition of such Registrable Securities, including customary holdback / lock-up provisions.

Statement covering a public offering of securities of the Company under the Securities Act shall have become effective, its insider trading policy shall provide that the directors of the Company may implement a trading program under Rule 10b5-1 of the Exchange Act. 
 2.5    Furnish Information. It shall be a
condition precedent to the obligations of the Company to take any action pursuant to this Section 2 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such

proceeding begun pursuant to Subsection 2.1 of the Existing Registration Rights Agreement if the registration request is subsequently withdrawn at the request of the Initiating Holder(s) (in which case all selling Holders shall bear such expenses
pro rata based upon the number of Registrable Securities that were to be included in the withdrawn registration), unless the Initiating Holder(s) agree to forfeit their right to one registration; provided further, that if, at the time
of such withdrawal, the Holders shall have learned of a material adverse change in the condition, business, or prospects of the Company from that known to the Holders at the time of their request and have withdrawn the request with reasonable
promptness after learning of such information then the Holders shall not be required to pay any of such expenses. All Selling Expenses relating to Registrable Securities registered pursuant to this Section 2 shall be borne
and paid by the Holders pro rata on the basis of the number of Registrable Securities registered on their behalf. 

2.7    Delay of Registration. No Holder shall have any right to obtain or seek an injunction restraining or
otherwise delaying any registration pursuant to this Agreement as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2. 

2.8    Indemnification. If any Registrable Securities are included in a Registration Statement under this
Section 2: 
 (a)    To the extent permitted by law, the Company will indemnify and hold
harmless each selling Holder, and the partners, members, officers, directors, and stockholders of each such Holder; legal counsel and accountants for each such Holder; any underwriter (as defined in the Securities Act) for each such Holder; and each
Person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any Damages, and the Company will pay to each such Holder, underwriter, controlling Person, or other aforementioned Person
any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement
contained in this Subsection 2.8(a) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall
the Company be liable for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any such Holder, underwriter, controlling
Person, or other aforementioned Person expressly for use in connection with such registration. 
 (b)    To the extent
permitted by law, each selling Holder, severally and not jointly, will indemnify and hold harmless the Company, and each of its directors, each of its officers who has signed the Registration Statement, each Person (if any) who controls the Company
within the meaning of the Securities Act, legal counsel and accountants for the Company, any underwriter (as defined in the Securities Act), any other Holder selling securities in such Registration Statement, and any controlling Person of any such
underwriter or other Holder, against any Damages, in each case only to the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of
such selling Holder expressly for use in connection with such registration; and each such selling Holder will pay to the Company and each other aforementioned Person any legal or other expenses reasonably incurred thereby in connection with
investigating or defending any 

  
 9 

 
claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Subsection 2.8(b) shall
not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and provided further, that in no event shall
the aggregate amounts payable by any Holder by way of indemnity or contribution under Subsections 2.8(b) and 2.8(d) exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except
in the case of fraud or willful misconduct by such Holder. 
 (c)    Promptly after receipt by an indemnified party
under this Subsection 2.8 of notice of the commencement of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made
against any indemnifying party under this Subsection 2.8, give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in such action and, to the extent the indemnifying party so
desires, participate jointly with any other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together
with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified
party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such action. The failure to give notice
to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Subsection 2.8, to the extent that such failure materially
prejudices the indemnifying party’s ability to defend such action. The failure to give notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Subsection
2.8. 
 (d)    To provide for just and equitable contribution to joint liability under the Securities Act in any
case in which either: (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Subsection 2.8 but it is judicially determined (by the entry of a final judgment or decree by a court
of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that this Subsection 2.8 provides for
indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any party hereto for which indemnification is provided under this Subsection 2.8, then, and in each such case, such parties will
contribute to the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of each of the indemnifying party and the
indemnified party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect any other relevant equitable considerations. The relative fault of the
indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact, or the omission or alleged omission of a material fact, relates to
information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission; provided, however,
that, in any such case (x) no Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such Holder pursuant to such Registration Statement, and (y) no
Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and provided
further, that in no event shall a Holder’s liability pursuant to this Subsection 2.8(d), when combined with the amounts paid or payable by such Holder pursuant to Subsection 2.8(b), exceed the proceeds from the offering
received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of willful misconduct or fraud by such Holder. 

  
 10 

 (e)    Notwithstanding the foregoing, to the extent that the provisions
on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

 (f)    Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten
public offering, the obligations of the Company and Holders under this Subsection 2.8 shall survive the completion of any offering of Registrable Securities in a registration under this Section 2, and otherwise shall
survive the termination of this Agreement. 
 2.9    Reports Under Exchange Act. With a view to
making available to the Holders the benefits of SEC Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company shall: 
 (a)    make and keep available adequate current public
information, as those terms are understood and defined in SEC Rule 144, at all times after the effective date of the Registration Statement filed by the Company for the IPO; 

(b)    use commercially reasonable efforts to file with the SEC in a timely manner all reports and other documents
required of the Company under the Securities Act and the Exchange Act (at any time after the Company has become subject to such reporting requirements); and 

(c)    furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) to
the extent accurate, a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after ninety (90) days after the effective date of the Registration Statement filed by the Company for the
IPO), the Securities Act, and the Exchange Act (at any time after the Company has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form
S-3 (at any time after the Company so qualifies); and (ii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any
such securities without registration (at any time after the Company has become subject to the reporting requirements under the Exchange Act) or pursuant to Form S-3 (at any time after the Company so qualifies
to use such form). 
 2.10    Limitations on Registration Rights. Notwithstanding anything to the contrary, the
Holders have no right to, and shall not, (a) include any Registrable Securities in any registration except to the extent that the inclusion of such Registrable Securities will not reduce the number of securities of the parties to the Existing
Registration Rights Agreement that are included; or (b) initiate a demand for registration of any Registrable Securities held by such Holder. 

2.11    “Market Stand-off” Agreement. Each Holder
hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final Prospectus relating to the registration by the Company for its own behalf of shares or units (as
applicable) of its Common Stock or any other equity securities under the Securities Act on a Registration Statement on Form S-1, or Form S-3, and ending on the date
specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days in the case of the IPO), (a) lend; offer; pledge; sell; contract to sell; sell any option or contract to purchase; purchase any
option or contract to sell; grant any option, right, or warrant to purchase; or otherwise transfer or dispose of, directly or indirectly, any shares or units (as applicable) of Common Stock or any securities convertible into or exercisable or
exchangeable (directly or indirectly) for Common Stock held immediately before the effective date of the Registration Statement for such offering or (b) enter into any 

  
 11 

 
swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause
(a) or (b) above is to be settled by delivery of Common Stock or other securities, in cash, or otherwise. The foregoing provisions of this Subsection 2.11 shall apply only to the IPO, shall not apply to the sale of any shares or units
(as applicable) to an underwriter pursuant to an underwriting agreement, or the transfer of any shares or units (as applicable) to any trust for the direct or indirect benefit of the Holder or the immediate family of the Holder, provided that
the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further, that any such transfer shall not involve a disposition for value, and shall be applicable to the Holders only if all
officers and directors are subject to the same restrictions and the Company uses commercially reasonable efforts to obtain a similar agreement from all Holders individually owning more than one percent (1%) of the Company’s outstanding Common
Stock (after giving effect to conversion into Common Stock of any other outstanding securities of the Company). The underwriters in connection with such registration are intended third-party beneficiaries of this Subsection 2.11 and shall
have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in connection with such registration
that are consistent with this Subsection 2.11 or that are necessary to give further effect thereto. Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply
pro rata to all Holders subject to such agreements, based on the number of shares or units (as applicable) subject to such agreements. 

2.12    Restrictions on Transfer. 

(a)    Each certificate, instrument, or book entry representing (i) the Common Stock, (ii) the Registrable
Securities, and (iii) any other securities issued in respect of the securities referenced in clauses (i) and (ii), upon any stock split, stock dividend, recapitalization, merger, consolidation, or similar event, shall (unless otherwise
permitted by the provisions of Subsection 2.12 (b)) be notated with a legend substantially in the following form: 
 THE SECURITIES
REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. SUCH SHARES OR UNITS (AS APPLICABLE) MAY NOT BE SOLD, PLEDGED, OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR A VALID
EXEMPTION FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SAID ACT. THE SECURITIES REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON
FILE WITH THE SECRETARY OF THE COMPANY. 
 The Holders consent to the Company making a notation in its records and giving instructions to
any transfer agent of the Restricted Securities in order to implement the restrictions on transfer set forth in this Subsection 2.12. 

(b)    The holder of such Restricted Securities, by acceptance of ownership thereof, agrees to comply in all respects with
the provisions of this Section 2. Before any proposed sale, pledge, or transfer of any Restricted Securities, unless there is in effect a Registration Statement under the Securities Act covering the proposed transaction,
the Holder thereof shall give notice to the Company of such Holder’s intention to effect such sale, pledge, or transfer. Each such notice shall describe the manner and circumstances of the proposed sale, pledge, or transfer in sufficient detail
and, if reasonably requested by the Company, shall be accompanied at such Holder’s expense by either (i) a written opinion of legal counsel who shall, and whose legal opinion shall, be reasonably satisfactory to the Company, addressed to
the 

  
 12 

 
Company, to the effect that the proposed transaction may be effected without registration under the Securities Act; (ii) a “no action” letter from the SEC to the effect that the
proposed sale, pledge, or transfer of such Restricted Securities without registration will not result in a recommendation by the staff of the SEC that action be taken with respect thereto; or (iii) any other evidence reasonably satisfactory to
counsel to the Company to the effect that the proposed sale, pledge, or transfer of the Restricted Securities may be effected without registration under the Securities Act, whereupon the Holder of such Restricted Securities shall be entitled to
sell, pledge, or transfer such Restricted Securities in accordance with the terms of the notice given by the Holder to the Company. The Company will not require such a legal opinion or “no action” letter (x) in any transaction in
compliance with SEC Rule 144; or (y) in any transaction in which such Holder distributes Restricted Securities to an Affiliate of such Holder for no consideration; provided that each transferee agrees in writing to be subject to the
terms of this Subsection 2.12. Each certificate, instrument, or book entry representing the Restricted Securities transferred as above provided shall be notated with, except if such transfer is made pursuant to SEC Rule 144, the appropriate
restrictive legend set forth in Subsection 2.12(a) except that such certificate instrument, or book entry shall not be notated with such restrictive legend if, in the opinion of counsel for such Holder and the Company, such legend is not
required in order to establish compliance with any provisions of the Securities Act. 
 2.13    Termination of
Registration Rights. The right of any Holder to request registration or inclusion of Registrable Securities in any registration pursuant to Subsection 2.2 shall terminate at such time as SEC Rule 144(b)(1) under the Securities Act (or any
successor provision) is available for the sale of all of such Holder’s shares without any need to comply with the public information requirements of SEC Rule 144(b)(1) (or any successor provision) or any such shares are sold pursuant to SEC
Rule 144. 
 3.    Miscellaneous. 

3.1    Successors and Assigns. The rights under this Agreement may be assigned (but only with all related
obligations) by a Holder to a transferee of Registrable Securities that (a) is an Affiliate of a Holder; (b) is a Holder’s Immediate Family Member or trust for the benefit of an individual Holder or one or more of such Holder’s
Immediate Family Members; or (c) after such transfer, holds at least one percent (1%) of the Company’s then outstanding Registrable Securities; provided, however, that (i) the Company is, within a reasonable time after
such transfer, furnished with written notice of the name and address of such transferee and the Registrable Securities with respect to which such rights are being transferred; and (ii) such transferee executes and delivers to the Company a
Joinder Agreement or a counterpart signature page to this Agreement, pursuant to which such Person will thereupon become a party to, and be bound by and obligated to comply with, the terms and provisions of this Agreement. For the purposes of
determining the number of shares or units (as applicable) of Registrable Securities held by a transferee, the holdings of a transferee (1) that is an Affiliate, member or stockholder of a Holder; (2) who is a Holder’s Immediate Family
Member; or (3) that is a trust for the benefit of an individual Holder or such Holder’s Immediate Family Member shall be aggregated together and with those of the transferring Holder; provided further, that all transferees
who would not qualify individually for assignment of rights shall have a single attorney-in-fact for the purpose of exercising any rights, receiving notices, or taking
any action under this Agreement. The terms and conditions of this Agreement inure to the benefit of and are binding upon the respective successors and permitted assignees of the parties. Nothing in this Agreement, express or implied, is intended to
confer upon any party other than the parties hereto or their respective successors and permitted assignees any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided herein. 

3.2    Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000,
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. 

  
 13 

 3.3    Titles and Subtitles. The titles and subtitles used in
this Agreement are for convenience only and are not to be considered in construing or interpreting this Agreement. 

3.4    Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing
and shall be deemed effectively given upon the earlier of actual receipt or (a) personal delivery to the party to be notified; (b) when sent, if sent by electronic mail or facsimile during the recipient’s normal business hours, and if
not sent during normal business hours, then on the recipient’s next Business Day; (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (d) one (1) Business Day after
the Business Day of deposit with a nationally recognized overnight courier, freight prepaid, specifying next-day delivery, with written verification of receipt. All communications shall be sent to the
respective parties at their addresses as set forth on Schedule A hereto, or to the principal office of the Company and to the attention of the Chief Executive Officer, in the case of the Company, or to such email address, facsimile number, or
address as subsequently modified by written notice given in accordance with this Subsection 3.4. 

3.5    Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this
Agreement may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written consent of the Company and the Holders of seventy-five percent (75%) of the Registrable Securities then
outstanding; provided that the Company may in its sole discretion enter into any number of Joinder Agreements with shareholders of the Company and, from time to time, update and distribute Schedule A to reflect any such updates; and
provided further, that the Company may in its sole discretion waive compliance with Subsection 2.12(b) (and the Company’s failure to object promptly in writing after notification of a proposed assignment allegedly in
violation of Subsection 2.12(b) shall be deemed to be a waiver); and provided further, that any provision hereof may be waived by any waiving party on such party’s own behalf, without the consent of any other party. The
Company shall give prompt notice of any amendment or termination hereof or waiver hereunder to any party hereto that did not consent in writing to such amendment, termination, or waiver. Any amendment, termination, or waiver effected in accordance
with this Subsection 3.5 shall be binding on all parties hereto, regardless of whether any such party has consented thereto. No waivers of or exceptions to any term, condition, or provision of this Agreement, in any one or more instances,
shall be deemed to be or construed as a further or continuing waiver of any such term, condition, or provision. 

3.6    Severability. In case any one or more of the provisions contained in this Agreement is for any reason held
to be invalid, illegal or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision of this Agreement, and such invalid, illegal, or unenforceable provision shall be reformed and construed so
that it will be valid, legal, and enforceable to the maximum extent permitted by law. 
 3.7    Entire Agreement.
This Agreement (including any Schedules and Exhibits hereto) constitutes the full and entire understanding and agreement among the parties with respect to the subject matter hereof (other than any lock-up or
similar agreement between any Holder and any underwriter), and any other written or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled. This Agreement hereby amends, restates and supersedes the
Original Piggy-back Registration Rights Agreement in all respects. 
 3.8    Governing Law; Jurisdiction. This
Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without regard to the conflicts of law principles of such State. The parties (a) hereby irrevocably and unconditionally submit to the
jurisdiction of the courts 

  
 14 

 
of the State of Delaware sitting in New Castle County and to the jurisdiction of the United States District Court sitting in Wilmington, Delaware for the purpose of any suit, action or other
proceeding arising out of or based upon this Agreement, (b) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in the courts of the State of Delaware sitting in New Castle County or the
United States District Court sitting in Wilmington, Delaware, and (c) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to
the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the
suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court. 

3.9    WAIVER OF JURY TRIAL. EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT OF THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS, THE SECURITIES OR THE SUBJECT MATTER HEREOF OR THEREOF. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL
DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION, INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS (INCLUDING NEGLIGENCE), BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY
CLAIMS. THIS SECTION HAS BEEN FULLY DISCUSSED BY EACH OF THE PARTIES HERETO AND THESE PROVISIONS WILL NOT BE SUBJECT TO ANY EXCEPTIONS. EACH PARTY HERETO HEREBY FURTHER WARRANTS AND REPRESENTS THAT SUCH PARTY HAS REVIEWED THIS WAIVER WITH ITS LEGAL
COUNSEL, AND THAT SUCH PARTY KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. 

3.10    Delays or Omissions. No delay or omission to exercise any right, power, or remedy accruing to any party
under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power, or remedy of such nonbreaching or nondefaulting party, nor shall it be construed to be a waiver of or acquiescence to any
such breach or default, or to any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. All remedies, whether under
this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative. 

3.11    Other Interpretive Matters. For purposes of this Agreement, (a) when calculating the period of time
before which, within which or following which any act is to be done or step taken pursuant to this Agreement, the date that is the reference date in calculating such period is excluded, and if the last day of such period is a non-Business Day, the period in question ends on the next succeeding Business Day, (b) unless the context otherwise requires, all references in this Agreement to any “Section,” “Subsection”
or “Exhibit” are to the corresponding Section, Subsection or Exhibit of this Agreement, (c) the word “including,” or any variation thereof, means “including, without limitation” and does not limit any general
statement that it follows to the specific or similar items or matters immediately following it, and (d) all references to dollar amounts are expressed in United States Dollars. As used herein, the singular shall include the plural, the plural
shall include the singular and any use of the male or female gender shall include the other gender, all wherever the same shall be applicable and when the context shall admit or require. 

3.12    No Recourse. Notwithstanding anything to the contrary that may be expressed or implied in this Agreement,
and notwithstanding the fact that the Holders or their Affiliates or any of their or their successors or permitted assignees may be a partnership or a limited liability company, the Company, by its acceptance of the benefits hereof, covenants,
agrees and acknowledges that no Person other than the 

  
 15 

 
Holders and their respective successors and permitted assignees shall have any obligation hereunder, and that it has no rights of recovery against, and no recourse hereunder against, any former,
current or future director, officer, agent, advisor, attorney, representative, Affiliate, manager or employee of any Holder (or any of its successors or assignees), against any former, current or future general or limited partner, manager, member or
stockholder of any Holder or any Affiliate thereof or against any former, current or future director, officer, agent, advisor, attorney, representative, employee, Affiliate, assignee, general or limited partner, stockholder, manager or member of any
of the foregoing, whether by or through attempted piercing of the corporate veil, by the enforcement of any judgment or assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable law. 

3.13    Specific Performance. The rights of each party to consummate the transactions contemplated hereby are
agreed to be unique, and recognizing that the remedy at law for any breach or threatened breach by a party hereto of the agreements and conditions set forth herein would be inadequate, and further recognizing that any such breach or threatened
breach would cause immediate, irreparable and permanent damage to the parties, the extent of which would be impossible or difficult to ascertain, the parties hereto agree that in the event of any such breach or threatened breach, and in addition to
any and all remedies at law or otherwise provided herein, any party hereto may specifically enforce the terms of this Agreement and may obtain temporary and/or permanent injunctive relief (including a mandatory injunction) without the necessity of
proving actual damage or the lack of an adequate remedy at law and, to the extent permissible under applicable rules, provision and statutes, a temporary injunction may be granted immediately upon the commencement of any suit hereunder regardless of
whether the breaching party or parties have actually received notice thereof. Such remedy shall be cumulative and not exclusive, and shall be in addition to any other remedy or remedies available to the parties. 

3.14    [Reserved].

Execution Version 

INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (“Agreement”) is made as of July 29, 2019, by and between Sunnova Energy International Inc., a
Delaware corporation (the “Company”) and Stuart D. Allen (“Indemnitee” and, together with the Company, the “Parties”). 

RECITALS: 
 WHEREAS,
managers, directors, officers and other persons in service to corporations and other business enterprises are subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally would have been brought
only against the Company or the business enterprise itself; 
 WHEREAS, highly competent persons have become more reluctant to serve as
managers, directors, officers or in other capacities unless they are provided with adequate protection through insurance and adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and
activities on behalf of the business enterprise; 
 WHEREAS, the Board of Directors of the Company (the “Board”) has determined
that the increased difficulty in attracting and retaining such persons is detrimental to the best interests of the Company and its shareholders, and that the Company should act to assure such persons that there will be increased certainty of such
protection in the future; 
 WHEREAS, the Bylaws of the Company (as they may be amended, the “Bylaws”) expressly require that the
Company indemnify its directors and officers, and empowers the Company to indemnify its employees and agents, as authorized by the Delaware General Corporation Law, as amended (the “DGCL”), under which the Company is organized and such
Bylaws expressly provide that the indemnification provisions set forth therein are not exclusive and thereby contemplate that contracts may be entered into between the Company and directors, officers and other persons with respect to
indemnification; 
 WHEREAS, this Agreement is a supplement to and in furtherance of the protections provided in applicable law, the Bylaws

its Affiliates, as the case may be, on the condition that he or she be furnished the indemnity provided for herein by the Company.

as to which Indemnitee shall have been finally adjudged by a court of competent jurisdiction to be liable to Indemnitor, unless and only to the extent that the Delaware Court of Chancery or any court in which the Proceeding was brought shall
determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to such indemnification. 

Section 4     Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any
other provisions of this Agreement, and without limiting the rights of Indemnitee under any other provision hereof, including any rights to indemnification pursuant to Sections 2 or 3 hereof, to the maximum extent permitted by applicable law,
to the extent that Indemnitee is successful, on the merits or otherwise, in defense of any Proceeding or any claim, issue or matter therein, in whole or in part, Indemnitor shall indemnify Indemnitee against all Expenses actually and reasonably
incurred by Indemnitee or on Indemnitee’s behalf in connection with each successfully resolved Proceeding, claim, issue or matter. For purposes of this Section 4 and without limitation, the termination of any Proceeding or claim, issue or
matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

Section 5     Indemnification For Expenses of a Witness. Notwithstanding any other provision of this

Affiliate of Indemnitor, a witness or otherwise a participant in any Proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses suffered or incurred (or, in the case of retainers, reasonably expected to be
incurred) by Indemnitee or on Indemnitee’s behalf in connection therewith. 
 Section 6     Additional
Indemnification. Notwithstanding any limitation in Sections 2, 3 or 4 hereof, Indemnitor shall indemnify Indemnitee to the maximum extent permitted by applicable law if Indemnitee is a party to or threatened to be made a party to or a
participant in any Proceeding (including a Proceeding by or in the right of Indemnitor to procure a judgment in its favor) against all Expenses suffered or reasonably incurred by Indemnitee in connection with such Proceeding, including but not
limited to: 
 (a) the fullest extent permitted by the provision of the DGCL that authorizes or contemplates additional indemnification by
agreement, or the corresponding provision of any amendment to or replacement of the DGCL; and 
 (b) the fullest extent authorized or
permitted by any amendments to or replacements of the DGCL adopted after the date of this Agreement that increase the extent to which a limited liability company or a corporation, as applicable, may indemnify its officers and Directors. 

 Section 7     Exclusions. Notwithstanding any provision in
this Agreement, Indemnitor shall not be obligated under this Agreement to indemnify or hold harmless Indemnitee in connection with any Proceeding (or any part of any Proceeding): 

(a) for which payment has actually been made to or on behalf of Indemnitee under any statute, indemnity, insurance policy, vote or otherwise,
except with respect to any excess beyond the amount paid, subject to any subrogation rights set forth in Section 13; 
 (b) for a
disgorgement or accounting of profits made pursuant to Section 16(b) of the Exchange Act or similar provisions of federal, state or local statutory law or common law, if Indemnitee is held liable therefor (including pursuant to any settlement
arrangements); 
 (c) except as provided in Section 12(d) of this Agreement, initiated by Indemnitee, including any Proceeding (or any
part of any Proceeding) initiated by Indemnitee against Indemnitor or its Directors, officers, employees, agents or other indemnitees, unless (i) the Board authorized the Proceeding (or the relevant part of any Proceeding) prior to its
initiation; (ii) Indemnitor provides the indemnification, in its sole discretion, pursuant to the powers vested in Indemnitor under applicable law; (iii) such Proceeding is being brought by Indemnitee to assert, interpret or enforce
Indemnitee’s rights under this Agreement (for the avoidance of doubt, Indemnitee shall not be deemed, for purposes of this subsection, to have initiated or brought any claim by reason of (A) having asserted any affirmative defenses in
connection with a claim not initiated by Indemnitee or (B) having made any counterclaim (whether permissive or mandatory) in connection with any claim not initiated by Indemnitee); or (iv) otherwise required by applicable law; 

(d) if a final, non-appealable decision by a court of competent jurisdiction in the matter shall determine that such indemnification is not
lawful; or 
 (e) for any claim, issue or matter as to which Indemnitee shall have (i) entered a plea of guilty or nolo contendere to a
felony or (ii) received a final, non-appealable judgment or verdict of guilty or its equivalent in any criminal proceeding. 

Section 8     Advancement. Indemnitor shall advance, to the maximum extent not prohibited by applicable law,
the Expenses reasonably incurred by Indemnitee in connection with any Proceeding (or any part of any Proceeding) not initiated by Indemnitee (other than pursuant to Section 7(c)(iii) or any Proceeding initiated by Indemnitee with the prior
approval of the Board as provided in Section 7(c)), and such advancement shall be made within thirty (30) days after the receipt by Indemnitor of a statement or statements requesting such advances from time to time (which shall include
invoices received by Indemnitee in connection with such Expenses but, in the case of invoices in connection with legal services, any references to legal work performed or to expenditure made that would cause Indemnitee to waive any privilege
accorded by applicable law shall not be required to be included with the invoice), whether prior to or after final disposition of any Proceeding. Advances shall be unsecured and interest free. Advances shall be made without regard to
Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement or otherwise than under this Agreement. Advances shall include any and all
Expenses reasonably incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to Indemnitor to support the advances claimed. Indemnitee shall qualify for advances upon the
execution and delivery to Indemnitor of this Agreement, which shall hereby constitute an undertaking providing that Indemnitee undertakes to repay any and all amounts advanced to the extent that it is ultimately determined by final judicial decision
from which there is no further right to appeal that Indemnitee is not entitled to be indemnified by Indemnitor under the terms of this Agreement, and no other form of undertaking shall be required other than the execution of this Agreement. Nothing
in this Section 8 shall limit Indemnitee’s right to advancement pursuant to Section 12(d) of this Agreement. This Section 8 shall not apply to any claim made by Indemnitee for which indemnification of Expenses is excluded pursuant to
Section 7 hereof. 

 Section 9    Procedure for Notification and Defense of
Claim. 
 (a) Indemnitee shall promptly notify Indemnitor in writing of any Proceeding with respect to which Indemnitee intends to seek
indemnification hereunder following the receipt by Indemnitee of written notice thereof. The written notification to Indemnitor shall include a description of the nature of the Proceeding and, to the extent known, the facts underlying the
Proceeding. To obtain indemnification under this Agreement, Indemnitee shall submit to Indemnitor a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably
necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of a Proceeding. Any delay or failure by Indemnitee to notify Indemnitor hereunder will not relieve Indemnitor from any
liability which it may have to Indemnitee hereunder or otherwise than under this Agreement, and any delay or failure in so notifying Indemnitor shall not constitute a waiver by Indemnitee of any rights under this Agreement. The Secretary of
Indemnitor shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. 

(b) In the event Indemnitee is entitled to indemnification and/or advancement of Expenses with respect to any Proceeding, Indemnitee may, at
Indemnitee’s option, (i) retain counsel (including local counsel) selected by Indemnitee and approved (which approval shall not be unreasonably withheld, conditioned or delayed) by Indemnitor to defend Indemnitee in such Proceeding, at the
sole expense of Indemnitor, or (ii) have Indemnitor assume the defense of Indemnitee in such Proceeding, in which case Indemnitor shall assume the defense of such Proceeding with counsel selected by Indemnitor and approved by Indemnitee (which
approval shall not be unreasonably withheld, conditioned or delayed) within ten (10) days of Indemnitor’s receipt of written notice of Indemnitee’s election to cause Indemnitor to do so. If Indemnitor is required to assume the defense
of any such Proceeding, it shall engage legal counsel (including local counsel) for such defense, and Indemnitor shall be solely responsible for all fees and expenses of such counsel and otherwise of such defense. Such counsel may represent both
Indemnitee and Indemnitor (and any other party or parties entitled to be indemnified by Indemnitor with respect to such matter) unless, in the reasonable opinion of counsel to Indemnitee, joint representation of all such parties could give rise to a
conflict of interest between Indemnitee and Indemnitor (or any other such party or parties) or there may be legal defenses available to Indemnitee that are not available to Indemnitor (or any such other party or parties). Notwithstanding a
Party’s assumption of responsibility for defense of a Proceeding, each Party shall have the right to engage separate counsel at its own expense. If Indemnitor has responsibility for defense of a Proceeding, Indemnitor shall provide the
Indemnitee and its counsel with all copies of pleadings and material correspondence relating to the Proceeding. Indemnitee and Indemnitor shall reasonably cooperate in the defense of any Proceeding with respect to which indemnification is sought
hereunder, regardless of whether Indemnitor or Indemnitee assumes the defense thereof. Indemnitee may not settle or compromise any Proceeding without the prior written consent of Indemnitor, which consent shall not be unreasonably withheld,
conditioned or delayed. Indemnitor may not settle or compromise any Proceeding without the prior written consent of Indemnitee. 

Section 10    Procedure Upon Application for Indemnification. 

(a) Upon written request by Indemnitee for indemnification pursuant to Section 9(a) hereof, if any determination by Indemnitor is required
by applicable law with respect to Indemnitee’s entitlement thereto, such determination shall be made (i) if Indemnitee shall request such determination be 

 
made by Independent Counsel, by Independent Counsel, and (ii) in all other circumstances, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the
Board, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (C) if there are no such Disinterested Directors or, if such Disinterested
Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee, or (D) if so directed by the Board, by the members or stockholders of Indemnitor; and, if it is so determined that
Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days after such determination. Indemnitee shall cooperate with the person, persons or entity making such determination with respect to
Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is
reasonably available to Indemnitee and reasonably necessary to such determination. Any Expenses incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by Indemnitor (irrespective of the
determination as to Indemnitee’s entitlement to indemnification) and Indemnitor hereby indemnifies and agrees to hold Indemnitee harmless therefrom and agrees to pay such Expenses as they are incurred. Indemnitor will not deny any written
request for indemnification hereunder made in good faith by Indemnitee unless a determination as to Indemnitee’s entitlement to such indemnification described in this Section 10(a) has been made. Indemnitor agrees to pay the reasonable
fees and expenses of the Independent Counsel referred to above and to fully indemnify such counsel against any and all Liabilities and Expenses arising out of or relating to this Agreement or its engagement pursuant hereto. 

(b) In the event the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 10(a)
hereof, (i) the Independent Counsel shall be selected by Indemnitor within ten (10) days of the Submission Date (the cost of such Independent Counsel to be paid by Indemnitor), (ii) Indemnitor shall give written notice to Indemnitee
advising it of the identity of the Independent Counsel so selected and (iii) Indemnitee may, within ten (10) days after such written notice of selection shall have been given, deliver to Indemnitor Indemnitee’s written objection to
such selection. Such objection by Indemnitee may be asserted only on the ground that the Independent Counsel selected does not meet the requirements of “Independent Counsel” as defined in this Agreement. If such written objection is made,
the Independent Counsel selected shall not serve as Independent Counsel unless and until Indemnitee withdraws the objection or a court has determined that such objection is without merit. Absent a timely objection, the person so selected shall act
as Independent Counsel. If no Independent Counsel shall have been selected and not objected to before the later of (i) thirty (30) days after the later of submission by Indemnitee of a written request for indemnification pursuant to
Section 10(a) hereof (the “Submission Date”) and (ii) ten (10) days after the final disposition of the Proceeding, each of Indemnitor and Indemnitee shall select a law firm or member of a law firm meeting the qualifications to
serve as Independent Counsel, and such law firms or members of law firms shall select the Independent Counsel. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 12(a) of this Agreement, Independent Counsel
shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 

Section 11    Presumptions and Effect of Certain Proceedings. 

(a) In making a determination with respect to entitlement to indemnification hereunder, the person, persons or entity making such determination
shall, to the fullest extent not prohibited by applicable law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 9(a) of this
Agreement, and Indemnitor shall, to the fullest extent not prohibited by applicable law, have the burden of proof to overcome 

 
that presumption by clear and convincing evidence in connection with the making by any person, persons or entity of any determination contrary to that presumption. Neither (i) the
failure of Indemnitor (including by its Directors, the Board, any committee or subgroup of the Board, Independent Counsel or stockholders) to have made a determination that indemnification is proper in the circumstances because Indemnitee has met
the applicable standard of conduct, nor (ii) an actual determination by Indemnitor (including by its Directors, the Board, any committee or subgroup of the Board, Independent Counsel or stockholders) that Indemnitee has not met such applicable
standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(b) Subject to Section 12(e) hereof, if the person, persons or entity empowered or selected under Section 10 of this Agreement to
determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by Indemnitor of the request therefor, the requisite determination of entitlement to indemnification shall, to
the fullest extent not prohibited by applicable law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary
to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be extended
for a reasonable time, not to exceed an additional thirty (30) days, if (i) the determination is to be made by Independent Counsel and Indemnitee objects to Indemnitor’s selection of Independent Counsel and (ii) the Independent
Counsel ultimately selected requires such additional time for the obtaining or evaluating of documentation or information relating thereto; provided further, however, that such 60-day period may also be extended for a reasonable time, not to exceed
an additional sixty (60) days, if the determination of entitlement to indemnification is to be made by the members or stockholders of Indemnitor. 

(c) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea
of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification under this Agreement or create a presumption that Indemnitee did not act
in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of Indemnitor or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was
unlawful. 
 (d) For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if Indemnitee
relied in good faith on (i) the records or books of account of the Enterprise, including financial statements, (ii) information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, (iii) the advice
of legal counsel for the Enterprise, or its board of directors or counsel selected by any committee of the board of directors, (iv) information or records given or reports made to the Enterprise by an independent certified public accountant,
appraiser, investment banker or other expert selected with reasonable care by the Enterprise or its board of directors or any committee thereof or (v) if the Indemnitee has met any other related standard set forth in the Governing Documents.
The provisions of this Section 11(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement or otherwise.

 (e) The knowledge or actions, or failure to act, of any Director, officer, employee or agent of the Enterprise shall not be imputed to
Indemnitee for purposes of determining the right to indemnification under this Agreement. 

 Section 12    Remedies of Indemnitee. 

(a) Subject to Section 12(e) hereof, in the event that (i) a determination is made pursuant to Section 10 of
this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement is not timely made pursuant to Section 8 or 12(d) of this Agreement, (iii) no determination of entitlement to indemnification
shall have been made pursuant to Section 10(a) of this Agreement within sixty (60) days after the later of receipt by Indemnitor of the request for indemnification or the final disposition of the Proceeding, (iv) payment of
indemnification pursuant to this Agreement is not made (A) within thirty days after a determination has been made that Indemnitee is entitled to indemnification or (B) pursuant to Sections 4 or 5 or the last sentence of Section 10(a)
of this Agreement within ten (10) days after receipt by Indemnitor of a written request therefor, (v) payment of indemnification pursuant to Sections 2, 3 or 6 of this Agreement is not made within ten (10) days after a determination
has been made that Indemnitee is entitled to indemnification, or (vi) in the event that Indemnitor or any other Person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other
action or proceeding designed to deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by the Delaware Court of Chancery of Indemnitee’s
entitlement to such indemnification or advancement. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration with respect to his or her entitlement to such indemnification or advancement of Expenses, to be conducted
by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which
Indemnitee first has the right to commence such proceeding pursuant to this Section 12(a). Indemnitor shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 

(b) In the event that a determination shall have been made pursuant to Section 10 of this Agreement that Indemnitee is not entitled to
indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 12 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that
adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 12 Indemnitor shall, to the fullest extent not prohibited by law, have the burden of proving Indemnitee is not entitled to indemnification or
advancement, as the case may be. 
 (c) If a determination shall have been made pursuant to Section 10(a) of this Agreement that
Indemnitee is entitled to indemnification, Indemnitor shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 12, absent (i) a misstatement by Indemnitee of a material fact, or an
omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) Indemnitor shall, to the fullest extent not prohibited by applicable law, be precluded from asserting in any judicial proceeding or
arbitration commenced pursuant to this Section 12 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that Indemnitor is bound by all
the provisions of this Agreement. It is the intent of Indemnitor that Indemnitee not be required to incur Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement (or under any
directors’ and officers’ liability insurance policies maintained by Indemnitor or any Affiliate of Indemnitor) by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be
extended to Indemnitee hereunder. Indemnitor shall indemnify Indemnitee against any and all such Expenses and, if requested by Indemnitee, shall (as soon as reasonably practicable, but in any event 

 
no later than within thirty (30) days after receipt by Indemnitor of a written request therefor) advance, to the maximum extent not prohibited by applicable law, such Expenses to Indemnitee,
as they are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advancement from Indemnitor under this Agreement or under any directors’ and officers’ liability insurance policies maintained by
Indemnitor or any Affiliate of Indemnitor, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement or insurance recovery, as the case may be. 

(e) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement
shall be required to be made prior to the final disposition of the Proceeding, including any appeal thereof; provided that, for the avoidance of doubt, in the absence of any such determination as to indemnification prior to the final
disposition of such Proceeding, Indemnitor shall advance Expenses as they are incurred with respect to such Proceeding. 

Section 13    Non-Exclusivity; Survival of Rights; Insurance; Subrogation. 

(a) The rights of indemnification and to receive advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any
other rights to which Indemnitee may at any time be entitled under applicable law, Indemnitor’s Governing Documents, any agreement, a vote of members or stockholders or a resolution of Directors, or otherwise. No amendment, alteration or repeal
of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee by reason of Indemnitee’s Corporate Status prior to such amendment,
alteration or repeal. To the extent that a change in Delaware law, whether by statute or judicial decision, permits greater indemnification or advancement than would be afforded currently under Indemnitor’s Governing Documents or this
Agreement, it is the intent of the Parties that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other
right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not
prevent the concurrent assertion or employment of any other right or remedy. 
 (b) Indemnitor hereby acknowledges that Indemnitee may have
certain rights to indemnification, advancement of Expenses and insurance provided by one or more Persons with whom or which Indemnitee may be associated. To the extent not in contravention of any insurance policy or policies providing liability or
other insurance for the Company or any director, trustee, general partner, managing member, officer, employee, agent or fiduciary of the Company or any other Enterprise, Indemnitor hereby acknowledges and agrees that (i) Indemnitor shall be the
indemnitor of first resort with respect to any Proceeding, Expense, Liability or matter that is the subject of the Indemnity Obligations, (ii) Indemnitor shall be primarily liable for all Indemnity Obligations and any indemnification afforded
to Indemnitee in respect of any Proceeding, Expense, Liability or matter that is the subject of Indemnity Obligations, whether created by applicable law, organizational or constituent documents, contract (including this Agreement) or otherwise,
(iii) any obligation of any other Persons with whom or which Indemnitee may be associated to indemnify Indemnitee or advance Expenses or Liabilities to Indemnitee in respect of any Proceeding shall be secondary to the obligations of Indemnitor
hereunder, (iv) Indemnitor shall be required to indemnify Indemnitee and advance Expenses or Liabilities to Indemnitee hereunder to the fullest extent provided herein without regard to any rights Indemnitee may have against any other Person
with whom or which Indemnitee may be associated or insurer of any such Person and (v) Indemnitor irrevocably waives, relinquishes and releases any other Person with whom or which Indemnitee may be associated from any claim of contribution,
subrogation or any other recovery of any kind in respect of amounts paid by 

 
Indemnitor hereunder. In the event any other Person with whom or which Indemnitee may be associated or their insurers advances or extinguishes any liability or loss which is the subject of any
Indemnity Obligation owed by Indemnitor or payable under any Company insurance policy, the payor shall have a right of subrogation against Indemnitor or its insurer or insurers for all amounts so paid which would otherwise be payable by Indemnitor
or its insurer or insurers under this Agreement. In no event will payment of an Indemnity Obligation by any other Person with whom or which Indemnitee may be associated or their insurers affect the obligations of Indemnitor hereunder or shift
primary liability for any Indemnity Obligation to any other Person with whom or which Indemnitee may be associated. Any indemnification, insurance or advancement provided by any other Person with whom or which Indemnitee may be associated with
respect to any Liability arising as a result of Indemnitee’s Corporate Status or capacity as an officer or Director of any Person is specifically in excess over any Indemnity Obligation of Indemnitor or any collectible insurance (including but
not limited to any malpractice insurance or professional errors and omissions insurance) provided by Indemnitor under this Agreement. The Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable
hereunder (or for which advancement is provided hereunder) if and to the extent that Indemnitee has otherwise actually received payment for such amounts under any insurance policy, contract, agreement or otherwise, subject to any subrogation right
set forth in this Section 13. 
 (c) To the extent that Indemnitor maintains an insurance policy or policies providing liability
insurance for Directors, officers, trustees, general partners, managing members, employees, fiduciaries, or agents of Indemnitor or of any other Enterprise, Indemnitee shall be covered by such policy or policies in accordance with its or their terms
to the maximum extent of the coverage available for any such Director, officer, trustee, general partner, managing member, employee, fiduciary or agent under such policy or policies and such policies shall provide for and recognize that the
insurance policies are primary to any rights to indemnification, advancement or insurance proceeds to which Indemnitee may be entitled from one or more Persons with whom or which Indemnitee may be associated to the same extent as Indemnitor’s
indemnification and advancement obligations set forth in this Agreement. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, Indemnitor has director and officer liability insurance in effect, Indemnitor shall give
prompt notice of the commencement of such Proceeding to the insurers in accordance with the procedures set forth in the respective policies. Indemnitor shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf
of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. 
 (d) In the event of any
payment under this Agreement, Indemnitor shall not be subrogated to the rights of recovery of Indemnitee, including rights of indemnification provided to Indemnitee from any other person or entity with whom Indemnitee may be associated; provided,
however, that Indemnitor shall be subrogated to the extent of any such payment of all rights of recovery of Indemnitee under insurance policies of Indemnitor or any of its subsidiaries. 

(e) The indemnification and contribution provided for in this Agreement will remain in full force and effect regardless of any investigation
made by or on behalf of Indemnitee. 
 Section 14     Duration of Agreement; Not Employment
Contract.     This Agreement shall continue until and terminate upon the latest of: (a) ten (10) years after the date that Indemnitee shall have ceased to serve as a Director, officer, employee, fiduciary or agent of
Indemnitor or any other Enterprise and (b) for so long as any Proceeding, including any appeal thereof, is pending in respect of which Indemnitee is granted rights of indemnification or advancement hereunder and of any proceeding, including any
appeal thereof, commenced by Indemnitee pursuant to Section 12 of this Agreement relating thereto, even after Indemnitee has ceased to serve as a director or officer of the Company or as a director, officer,

 
trustee, general partner, managing member, officer, employee, agent or fiduciary of any other Enterprise, as applicable, and for one (1) year after the final termination of any such
Proceeding, including any appeal, and of any proceeding commenced by Indemnitee pursuant to Section 12 relating thereto. This Agreement shall be binding upon Indemnitor and its successors and assigns, including, without limitation, any
corporation or other entity which may have acquired all or substantially all of Indemnitor’s assets or business or into which Indemnitor may be reorganized, consolidated or merged or into which Indemnitor may elect to convert, and shall inure
to the benefit of Indemnitee and Indemnitee’s heirs, executors and administrators. This Agreement shall not be deemed an employment contract between Indemnitor (or any of its subsidiaries or any other Enterprise) and Indemnitee. Indemnitee
specifically acknowledges that Indemnitee’s employment with Indemnitor (or any of its subsidiaries or any other Enterprise), if any, is at will, and Indemnitee may be discharged at any time for any reason, with or without cause, except as may
be otherwise provided in any written employment contract between Indemnitee and Indemnitor (or any of its subsidiaries or any other Enterprise), other applicable formal severance policies duly adopted by the Board, or, with respect to service as a
Director or officer of Indemnitor, by Indemnitor’s Governing Documents or Delaware law. 
 Section 15    
Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement
(including, without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable that is not itself invalid, illegal or unenforceable) shall not in any way be affected or
impaired thereby and shall remain enforceable to the fullest extent permitted by applicable law; (b) such provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to
the intent of the Parties; and (c) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or
unenforceable that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested thereby. 

Section 16    Enforcement. 

(a) Indemnitor expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order
to induce Indemnitee to serve as a Director, officer, employee, fiduciary or agent of Indemnitor, and Indemnitor acknowledges that Indemnitee is relying upon this Agreement in serving as a Director, officer, employee, fiduciary or agent of
Indemnitor. 
 (b) This Agreement constitutes the entire agreement among the Parties with respect to the subject matter hereof and
supersedes all prior agreements and understandings, oral, written and implied, among the Parties with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in furtherance of the Governing
Documents and applicable law, and shall not be deemed a substitute therefore, nor diminish or abrogate any rights of Indemnitee thereunder. 

Section 17     Modification and Waiver. No supplement, modification or amendment of this Agreement shall be
binding unless executed in writing by the Parties thereto. No amendment, alteration or repeal of this Agreement shall adversely affect any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his
or her Corporate Status prior to such amendment, alteration or repeal. No waiver of any of the provisions of this Agreement shall be deemed to be or shall constitute a waiver of any other provision of this Agreement nor shall any waiver constitute a
continuing waiver. 

 Section 18     Notices. All notices and other communications
required or permitted hereunder shall be in writing and shall be mailed by registered or certified mail, postage prepaid, sent by electronic mail or otherwise delivered by hand, messenger or courier service addressed: 

(a) if to Indemnitee, to Indemnitee’s address or electronic mail address as shown on the signature page of this Agreement or in the
Company’s records, as may be updated in accordance with the provisions hereof; or 
 (b) if to the Company, to the attention of the
Chief Executive Officer or Chief Financial Officer of the Company at Sunnova Energy International Inc., Attn: General Counsel, 20 Greenway Plaza, Suite 475, Houston, Texas 77046, or at such other current address of Indemnitor as Indemnitor shall
have furnished to Indemnitee for such purposes. 
 Each such notice or other communication shall for all purposes of this Agreement be
treated as effective or having been given (i) if delivered by hand, messenger or courier service, when delivered (or if sent via a nationally-recognized overnight courier service, freight prepaid, specifying next-business-day delivery, one
business day after deposit with the courier), or (ii) if sent via mail, at the earlier of its receipt or five days after the same has been deposited in a regularly-maintained receptacle for the deposit of the United States mail, addressed and
mailed as aforesaid, or (iii) if sent via electronic mail, upon confirmation of delivery when directed to the relevant electronic mail address, if sent during normal business hours of the recipient, or if not sent during normal business hours
of the recipient, then on the recipient’s next business day. 
 Section 19    Contribution. 

(a) Whether or not the indemnification provided in Sections 2, 3, 4, 5 and 6 hereof is available, in respect of any threatened, pending or
completed action, suit or proceeding in which Indemnitor is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), Indemnitor shall pay, in the first instance, the entire amount of any judgment or settlement of
such action, suit or proceeding without requiring Indemnitee to contribute to such payment and, to the fullest extent permitted by law, Indemnitor hereby waives and relinquishes any right of contribution it may have against Indemnitee. Indemnitor
shall not enter into any settlement of any action, suit or proceeding in which Indemnitor is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding) unless such settlement provides for a full and final and
unconditional release of all claims asserted against Indemnitee. 
 (b) To the maximum extent permitted by applicable law, if the
indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, Indemnitor, in lieu of indemnifying Indemnitee, shall contribute to the amounts incurred by Indemnitee, whether for Liabilities or for Expenses,
in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits
received by Indemnitor and Indemnitee as a result of the event(s) and transaction(s) giving cause to such Proceeding; and (ii) the relative fault of Indemnitor (and its Directors, officers, employees and agents) and Indemnitee in connection
with such event(s) and transaction(s). 
 Section 20     Applicable Law and Consent to Jurisdiction. This
Agreement and the legal relations among the Parties shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of laws rules. Except with respect to any arbitration
commenced by Indemnitee pursuant to Section 12(a) of this Agreement, the Parties hereby irrevocably and 

 
unconditionally (a) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought only in the Delaware Court of Chancery, and not in any other
state or federal court in the United States of America or any court in any other country, (b) consent to submit to the exclusive jurisdiction of the Delaware Court of Chancery for purposes of any action or proceeding arising out of or in
connection with this Agreement, (c) waive any objection to the laying of venue of any such action or proceeding in the Delaware Court of Chancery, and (d) waive, and agree not to plead or to make, any claim that any such action or
proceeding brought in the Delaware Court of Chancery has been brought in an improper or inconvenient forum. 

Section 21     Counterparts. This Agreement may be executed in one or more counterparts, each of which shall
for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the Party against whom enforceability is sought needs to be produced to evidence the existence of
this Agreement. 
 Section 22     Miscellaneous. Use of the masculine pronoun shall be deemed to include
usage of the feminine pronoun where appropriate. The headings of the paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof.
