 (ii) The execution and delivery by the Purchaser of this Agreement and the fulfillment
of and compliance with the terms hereof by the Purchaser does not and shall not as of each Closing Date conflict with or result in a breach by the Purchaser of the terms, conditions or provisions of any agreement, instrument, order, judgment or
decree to which the Purchaser is subject that would materially impact its ability to perform its obligations hereunder. 

C. Investment Representations. 

(i) The Purchaser is acquiring the Private Placement Warrants and, upon exercise of the Private Placement Warrants, the Shares issuable

(ii) The Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D of the
Securities Act of 1933, as amended (the “Securities Act”), and the Purchaser has not experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Securities Act. 

(iii) The Purchaser understands that the Securities are being offered and will be sold to it in reliance on 

specific exemptions from the registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth
and accuracy of, and the Purchaser’s compliance with, the representations and warranties of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire such
Securities. 
 (iv) The Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general
advertising within the meaning of Rule 502(c) under the Securities Act. 
 (v) The Purchaser has been furnished with all
materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by the Purchaser. The Purchaser has been afforded the opportunity to ask questions of
the executive officers and directors of the Company. The Purchaser understands that its investment in the Securities involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an
informed investment decision with respect to the acquisition of the Securities. 
 (vi) The Purchaser understands that no United States

reliance on an exemption therefrom; and (b) except as specifically set forth in the Registration Rights Agreement, neither the Company nor any other person is under any obligation to register the Securities under the Securities Act or any state
securities laws or to comply with the terms and conditions of any exemption thereunder. While the Purchaser understands that Rule 144 under the Securities Act is not available for the resale of securities initially issued by shell companies
(other than business combination related shell companies) or issuers that have been at any time previously a shell company, the Purchaser understands that Rule 144 includes an exception to this prohibition if the following conditions are met:
(i) the issuer of the securities that was formerly a shell company has ceased to be a shell company; (ii) the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act
of 1934, as amended (the “Exchange Act”); (iii) the issuer of the securities has filed all Exchange Act reports and material required to be filed, as applicable, during the preceding 12 months (or such shorter period that the
issuer was required to file such reports and materials), other than Form 8-K reports; and (iv) at least one year has elapsed from the time that the issuer filed current Form 10 type information
with the SEC reflecting its status as an entity that is not a shell company. 

 (viii) The Purchaser has knowledge and experience in financial and business matters,
understands the high degree of risk associated with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the Securities and is able to bear the
economic risk of an investment in the Securities in the amount contemplated hereunder for an indefinite period of time. The Purchaser has adequate means of providing for its current financial needs and contingencies and will have no current or
anticipated future needs for liquidity which would be jeopardized by the investment in the Securities. The Purchaser can afford a complete loss of its investment in the Securities.

obligations under this Agreement and to consummate the transactions contemplated hereby. This Agreement and the Stockholder Consent have been duly executed and delivered by the Stockholder and, assuming this Agreement constitutes a legal, valid and
binding obligation of the other parties hereto and thereto, constitute a valid and binding agreement of the Stockholder enforceable against the Stockholder in accordance with its terms, subject to the Bankruptcy and Equity Exceptions. The
Stockholder has provided to Parent a true and correct excerpt of each provision of the Second Amended and Restated Limited Liability Company Agreement of the Stockholder dated as of September 15, 2019, as amended (the “Stockholder

be obtained by the Stockholder from, or to be given by the Stockholder to, or be made by the Stockholder with, any Governmental Entity in connection with the execution, delivery and performance by the Stockholder of this Agreement, the consummation
of the transactions contemplated hereby or the Merger and the other transactions contemplated by the Merger Agreement. 

  
 4 

 (e) The execution, delivery and performance of this Agreement and the
Stockholder Consent by the Stockholder do not, and the consummation of the transactions contemplated hereby and by the Stockholder Consent, and the Merger and the other transactions contemplated by the Merger Agreement will not, constitute or result
in (i) a breach or violation of, or a default under, the certificate of incorporation, bylaws or comparable organizational documents of the Stockholder, (ii) with or without notice, lapse of time or both, a breach or violation of a
termination (or right of termination) of or a default under, the loss of any benefit under, the creation, modification, cancellation or acceleration (or the right of modification, cancellation or acceleration) of any obligations under or the
creation of a Lien on any of the properties, rights or assets (including the Covered Shares) of the Stockholder pursuant to any Contract binding upon the Stockholder or, assuming (solely with respect to performance of this Agreement and the
transactions contemplated hereby), compliance with the matters referred to in Section 4(d), under any applicable Law, rule, regulation, order, judgment or decree to which the Stockholder is subject or (iii) any change in the rights or
obligations of any party under any Contract legally binding upon the Stockholder, except, in the case of clause (ii) or (iii) directly above, for any such breach, violation, termination, default, creation, acceleration or change that would not,

Merger or the other transactions contemplated by the Merger Agreement.

connection with a Company Acquisition Proposal or potential Company Acquisition Proposal to return or destroy all confidential information furnished to such Third Party by or on behalf of it or any of its subsidiaries prior to the date hereof. The
Stockholder shall promptly (and in any event within one Business Day after the Stockholder’s knowledge of any such event) notify Parent of the receipt of (A) any Company Acquisition Proposal after the execution of this Agreement,
(B) any inquiry, proposal, offer or request for information with respect to, or that could reasonably be expected to result in or lead to, a Company Acquisition Proposal, or (C) any discussions or negotiations sought to be initiated or
continued with the Stockholder, the Company, any of its subsidiaries or its or their Representatives concerning a Company Acquisition Proposal, which notice shall include a summary of the material terms of, and the identity of the Third Party
making, such Company Acquisition Proposal, inquiry, offer, proposal or request for information and an unredacted copy of any Company Acquisition Proposal, inquiry, offer, proposal or request for information (including any proposed transaction
agreements (including any drafts thereof and all schedules and exhibits thereto) relating to any Company Acquisition Proposal) made in writing (including electronically) and a summary of terms and conditions of any Company Acquisition Proposal,
inquiry, offer, proposal or request for information not made in writing. Notwithstanding anything in this Agreement to the contrary, (x) the Stockholder (in its capacity as such) shall not be responsible for the actions of the Company or its
Board of Directors (or any Committee thereof), any Affiliate of the Company (other than the Stockholder), or any officers, directors (in their capacity as such), employees and Representatives of any of the foregoing (the “Company Related
Parties”), including with respect to any of the matters contemplated by this Section 5(a), (y) the Stockholder (in its capacity as such) makes no representations or warranties with respect to the actions of any of the Company Related
Parties, and (z) any 

  
 6 

 
breach by the Company of its obligations under Section 6.1(a) of the Merger Agreement shall not be considered a breach of this Section 5(a) (it being understood for the avoidance of
doubt that the Stockholder shall remain responsible for any breach by it or its Representatives (other than any such Representative that is a Company Related Party) of this Section 5(a)). 

(b) Transfer of the Covered Shares. 

(i) The Stockholder hereby agrees not to, directly or indirectly, (1) sell, transfer, pledge, encumber, assign, hedge,
swap, convert, gift-over or otherwise dispose of (including by sale, merger (including by conversion into securities or other consideration), by tendering into any tender or exchange offer, by testamentary disposition, by liquidation or dissolution,
by dividend or distribution, by operation of Law or otherwise), either voluntarily or involuntarily (collectively, “Transfer”), or enter into any Contract, option or other agreement, arrangement or understanding with respect to the
Transfer of any of the Stockholder’s Covered Shares or (2) take any action that would make any representation or warranty of the Stockholder contained herein untrue or incorrect or have the effect of preventing or disabling the Stockholder
from performing its obligations under this Agreement, provided, however, that (A) from and after the date of the Company Stockholders Meeting at which the Company Requisite Vote is obtained, the Stockholder and its Affiliates
shall be permitted to Transfer (and enter into any Contract or option with respect to any such Transfer) all or a portion of the Covered Shares on any two (2) days during any calendar month, provided, that any such Transfers are executed
at a price equal to or in excess of the lesser of (A) fifteen dollars ($15.00) per share of Company Common Stock and (B) ninety-six percent (96%) of the most recent closing price of the Company
Common Stock on the securities exchange or market on which the Company Common Stock is then listed or quoted; provided, further, that Parent shall not be required to take any actions in order to facilitate any such Transfer (such
shares of Company Common Stock Transferred from time to time, the “Transferable Amount”) and (B) nothing herein shall prohibit a Transfer (x) up to 1,849,347 shares of Company Common Stock in the aggregate pursuant to
Section 5.5 of the Stockholder Limited Liability Company Agreement (each, a “Permitted Redemption”) or (y) to an Affiliate of the Stockholder on the Closing Date (but prior to the Effective Time), in connection with a distribution-in-kind of shares of Company Common Stock pursuant to Section 5.5(e) of the Stockholder Limited Liability Company Agreement (a “Permitted
Transfer”); provided, further, that any Permitted Transfer shall be permitted only if, as a precondition to such Transfer, the transferee agrees in a writing, reasonably satisfactory in form and substance to Parent, to assume
all of the obligations of the Stockholder under, and be bound by all of the terms of, this Agreement. Any Transfer in violation of this Section 5(b) with respect to the Stockholder’s Covered Shares shall be null and void and the
Stockholder agrees that any such prohibited Transfer may and shall be enjoined. 

  
 7 

 (ii) In furtherance of this Agreement, Parent may, on the Stockholder’s
behalf, promptly after the date hereof, cause the Company to enter, or cause the Company’s transfer agent to enter, a stop transfer order with respect to all of the Stockholder’s Covered Shares with respect to any Transfer not permitted
hereunder and to include the following legend on any share certificates for the Stockholder’s Covered Shares: “THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN VOTING AND TRANSFER RESTRICTIONS PURSUANT TO THAT
CERTAIN SUPPORT AGREEMENT, DATED AS OF JULY 6, 2020, BY AND BETWEEN SUNRUN INC., A DELAWARE CORPORATION, AND 313 ACQUISITION LLC, A DELAWARE LIMITED LIABILITY COMPANY. ANY TRANSFER OF SUCH SHARES OF STOCK IN VIOLATION OF THE TERMS AND
PROVISIONS OF SUCH SUPPORT AGREEMENT SHALL BE NULL AND VOID AND HAVE NO FORCE OR EFFECT WHATSOEVER.” The delivery of such securities by the delivering party shall not in any way affect such party’s rights with respect to such securities.
Notwithstanding the foregoing, in connection with any Transfer of Transferable Amounts from time to time in accordance with Section 5(b)(i)(A), the Company shall be permitted to instruct its transfer agent to lift the stop
transfer order with respect to a number of the Stockholder’s shares of Company Common Stock equal to the Transferable Amount (and remove any restrictive legend on such shares). 

(iii) In the event that the Stockholder intends to undertake a Permitted Transfer of any of the Stockholder’s Covered
Shares, the Stockholder shall provide notice thereof to Parent and, if the written agreement to be entered into by the transferee agreeing to be bound by this Agreement pursuant to Section 5(b) hereof is reasonably satisfactory to Parent, the
Company shall be permitted to instruct its transfer agent to, (i) lift any stop transfer order in respect of the Stockholder’s Covered Shares to be so Transferred in order to effect such Permitted Transfer and (ii) re-enter any stop transfer order in respect of the Stockholder’s Covered Shares to be so Transferred upon completion of the Permitted Transfer. 

(c) Other Actions. 

(i) The Stockholder agrees that it shall not, and shall cause each of its Affiliates not to, become a member of a
“group” (as that term is used in Section 13(d) of the Exchange Act) that it is not currently a part of and that has been disclosed in a filing on Schedule 13D prior to the date hereof (other than as a result of entering into this
Agreement) with respect to any Covered Shares or other Company Securities for the purpose of opposing or competing with the transactions contemplated by the Merger Agreement. 

(ii) The Stockholder hereby authorizes Parent to maintain a copy of this Agreement at either the executive office or the
registered office of Parent. 
 (iii) The Stockholder will not, and agrees to cause the Blackstone Parties not to, amend,
alter, waive, terminate, modify or rescind the Stockholder Consent, provided, that the foregoing shall in no way limit the Stockholder’s or the Blackstone Parties’ rights with respect to the Excess Covered Shares, including, but not
limited to, the adoption any resolutions, consents or other approvals in favor of a transaction other than the transactions contemplated by the Merger Agreement.

 6. Further Assurances. From time to time, at Parent’s request and without
further consideration, the Stockholder shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or reasonably requested to effect the actions and consummate the transactions contemplated by
this Agreement. The Stockholder further irrevocably and unconditionally agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise,
against the Company, Parent or any of their respective successors and assigns relating to the negotiation, execution or delivery of this Agreement, the Merger Agreement or the consummation of the transactions contemplated hereby and thereby,
including any action (i) challenging the validity of, or seeking to enjoin the operation of, any provision of the Merger Agreement or this Agreement or (ii) alleging breach of any fiduciary duty of any Person in connection with the
negotiation and entry into the Merger Agreement, this Agreement or the transactions contemplated hereby or thereby. 
 7. Public
Announcements; Disclosure. The Stockholder shall not, and shall cause its Representatives not to, directly or indirectly, make any press release, public announcement or other public communication in respect of this Agreement or the Merger
Agreement or any of the transactions contemplated hereby and thereby without the prior written consent of Parent, except as required by applicable federal securities Laws; provided, that the foregoing limitations shall not apply following any
Company Change of Recommendation. The Stockholder hereby (i) authorizes Parent and the Company to publish and disclose in any announcement or disclosure required by the SEC (including in the Joint Proxy Statement and the Registration Statement)
the Stockholder’s identity and ownership of the Covered Shares, the nature of the Stockholder’s obligations under this Agreement and any other information that Parent or the Company determines to be necessary in any SEC disclosure document
and (ii) agrees as promptly as practicable to notify Parent and the Company of any required corrections with respect to any written information supplied by the Stockholder specifically for use in any such disclosure document. 

8. Changes in Capital Stock. In the event of a stock split, stock dividend or distribution, or any change in Parent’s capital stock
by reason of any split-up, reverse stock split, recapitalization, combination, reclassification, exchange of shares or the like between the date of this Agreement and the Effective Time, the terms “Owned
Shares”, “Covered Shares”, “Committed Covered Shares”, “Permitted Redemption” and “Transferable Amount” shall be deemed to refer to and include such shares as well as all such stock dividends and
distributions and any securities into which or for which any or all of such shares may be changed or exchanged or which are received in such transaction, in each case subject to Section 1(b) hereof. 

9. Amendment and Modification. This Agreement may not be amended, modified or supplemented in any manner, whether by course of conduct
or otherwise, except by an instrument in writing signed by Parent and the Stockholder.

 10. Waiver. No failure or delay by any party hereto exercising any right, power or
privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the parties
hereto hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder. Any agreement on the part of a party hereto to any such waiver shall be valid only if set forth in a written instrument
executed and delivered by such party. 
 11. Notices. All notices, requests, claims, demands and other communications hereunder shall
be in writing and shall be given (and shall be deemed to have been duly given upon receipt) by delivery in person, by e-mail, by overnight courier or by registered or certified mail (postage prepaid, return
receipt requested) to the respective parties at the following addresses (or at such other address for a party as shall be specified by like notice made pursuant to this Section 11):

 12. No Ownership Interest. Nothing contained in this Agreement shall be deemed to
vest in Parent any direct or indirect ownership or incidence of ownership of or with respect to the Covered Shares. All rights, ownership and economic benefits of and relating to the Covered Shares of the Stockholder shall remain vested in and
belong to the Stockholder, and Parent shall have no authority to direct the Stockholder in the voting or disposition of any of the Covered Shares, except as otherwise provided herein. 

13. Entire Agreement. This Agreement constitutes the entire agreement and supersedes all prior agreements and understandings, both
written and oral, between the parties hereto with respect to the subject matter hereof. Each of the parties hereto hereby acknowledges and agrees, on behalf of itself, its Affiliates and each of their respective Representatives, that, in connection
with such party’s entry into this Agreement and agreement to consummate the transactions contemplated hereby, neither such party nor any of its Affiliates or any of their respective Representatives has relied on any representations or
warranties except for the representations and warranties of the Stockholder expressly set forth in Section 4 of this Agreement. 

14. No Third-Party Beneficiaries. The Stockholder hereby agrees that its representations, warranties and covenants set forth herein are
solely for the benefit of Parent in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does not, confer upon any Person other than the parties hereto any rights or remedies hereunder, including the
right to rely upon the representations and warranties set forth herein, and the parties hereto hereby further agree that this Agreement may only be enforced against, and any Action that may be based upon, arise out of or relate to this Agreement, or
the negotiation, execution or performance of this Agreement may only be made against, the Persons expressly named as parties hereto; provided, however, that the Company shall be a third-party beneficiary of
Section 7 of this Agreement. 
 15. Governing Law and Venue; Service of Process; Waiver of Jury Trial. 

(a) This Agreement and any disputes relating hereto shall be governed by, and construed in accordance with, the laws of the
State of Delaware (without giving effect to choice of law or conflict of law principles thereof or of any other jurisdiction that would cause the application of any laws of any jurisdiction other than the State of Delaware). 

(b) Each of the parties hereto irrevocably (i) consents to submit itself to the personal jurisdiction of the Delaware
Court of Chancery and any state appellate court therefrom within the State of Delaware (unless the Delaware Court of Chancery shall decline to accept jurisdiction over a particular matter, in which case, in any Delaware state or federal court within
the State of Delaware), in connection with any matter based upon or arising out of this Agreement or any of the transactions contemplated by this Agreement or the actions of Parent or the Stockholder in the negotiation, administration, performance
and enforcement hereof and thereof, (ii) agrees that it will not attempt to 

  
 11 

 
deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (iii) agrees that it will not bring any action relating to this Agreement or any of the
transactions contemplated by this Agreement in any court other than the courts of the State of Delaware, as described above, and (iv) consents to service being made through the notice procedures set forth in Section 11. Each party hereto
agrees that service of any process, summons, notice or document by U.S. registered mail to the respective addresses set forth in Section 11 shall be effective service of process for any suit or proceeding in connection with this Agreement or
the transactions contemplated hereby. Each party hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, any claim that it is
not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to serve process in accordance with this Section 15(b), that it or its property is exempt or immune from jurisdiction of any such court
or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), and to the fullest extent permitted by applicable
Law, that the suit, action or proceeding in any such court is brought in an inconvenient forum, that the venue of such suit, action or proceeding is improper, or that this Agreement, or the subject matter hereof or thereof, may not be enforced in or
by such courts and further irrevocably waives, to the fullest extent permitted by applicable Law, the benefit of any defense that would hinder, fetter or delay the levy, execution or collection of any amount to which the party is entitled pursuant
to the final judgment of any court having jurisdiction. Each party expressly acknowledges that the foregoing waiver is intended to be irrevocable under the Laws of the State of Delaware and of the United States of America; provided that each
such party’s consent to jurisdiction and service contained in this Section 15(b) is solely for the purpose referred to in this Section 15(b) and shall not be deemed to be a general submission to said courts or in the State of Delaware
other than for such purpose. 
 (c) EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF PARENT OR THE STOCKHOLDER IN THE NEGOTIATION, ADMINISTRATION,
PERFORMANCE AND ENFORCEMENT HEREOF OR THEREOF. 
 16. Assignment; Successors. Neither this Agreement nor any of the rights, interests
or obligations hereunder shall be assigned by any of the parties hereto in whole or in part (whether by operation of Law or otherwise) without the prior written consent of the other party, and any such assignment without such consent shall be null
and void. This Agreement shall be binding upon, inure to the benefit of and be enforceable by the parties hereto and their respective successors and permitted assigns. 

  
 12 

 17. Enforcement. The parties hereto agree that irreparable damage for which monetary
damages, even if available, may not be an adequate remedy, would occur in the event that the parties hereto do not perform the provisions of this Agreement (including the Stockholder’s obligations to vote its Covered Shares as provided in this
Agreement) in accordance with its specified terms or otherwise breach such provisions. The parties hereto acknowledge and agree that the parties hereto shall be entitled to an injunction, specific performance and other equitable relief to prevent
breaches of this Agreement and to enforce specifically the terms and provisions hereof, without any requirement for the posting of security, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the
parties hereto agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief as provided herein on the basis that (x) either party has an adequate remedy at law or (y) an award of specific
performance is not an appropriate remedy for any reason at law or equity. 
 18. Severability. If any term or other provision of this
Agreement is found by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and
effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being
enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are
fulfilled to the fullest extent possible. 
 19. Counterparts. This Agreement may be executed and delivered (including by email
transmission, “.pdf,” or other electronic transmission) in one or more counterparts, and by the different parties in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall
constitute one and the same agreement. 
 20. Interpretation and Construction. When reference is made in this Agreement to a Section,
such reference shall be to a Section of this Agreement unless otherwise indicated. Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words
“without limitation.” The words “hereof,” “herein,” “hereby” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular
provision of this Agreement. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant thereto unless otherwise defined therein. Words of any gender include each
other gender and neuter genders and words using the singular or plural number also include the plural or singular number, respectively. Any Contract or Law defined or referred to herein means such Contract or Law as from time to time amended,
modified or supplemented, including (in the case of Contracts) by waiver or consent and (in the case of Laws) by succession or comparable successor statutes and references to all attachments thereto and instruments incorporated therein. The word
“or” shall not be exclusive. The word “will” shall be construed to have the same meaning as the word “shall”. Whenever this Agreement refers to a number of days, such number shall refer to calendar days unless Business
Days are specified. The word “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if”. Any deadline or time period set forth in this Agreement that by its terms
ends on a day that is not a Business Day shall be automatically extended to the next succeeding Business Day. Each of the parties hereto has participated in the drafting and negotiating of this Agreement. If an ambiguity or question of intent or
interpretation arises, this Agreement shall be construed as if it is drafted by all the parties hereto and without regard to any presumption or rule requiring construction or interpretation against the party drafting or causing any instrument to be
drafted. 

  
 13 

 21. Capacity as a Stockholder. Notwithstanding anything herein to the contrary, the
Stockholder signs this Agreement solely in the Stockholder’s capacity as a stockholder of the Company, and not in any other capacity and this Agreement shall not limit or otherwise affect the actions (including the exercise of fiduciary duties)
in accordance with applicable Law of any Affiliate, employee or designee of the Stockholder or any of its Affiliates in his or her capacity, if applicable, as an officer or director of the Company or any other Person. 

22. Expenses. All fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by
the party incurring such fees or expenses, whether or not the Merger is consummated.
