 ARTICLE I 

SPONSOR SUPPORT AGREEMENT; COVENANTS 

Section 1.1 Binding Effect of Merger Agreement. Each Sponsor hereby acknowledges that it has read the Merger Agreement and this

Agreement (and any relevant definitions contained in any such Sections) to the same extent as such provisions apply to Acquiror as if such Sponsor was an original signatory to the Merger Agreement with respect to such provisions. 

Section 1.2 No Transfer. During the period commencing on the date hereof and ending on the earliest of (a) the Effective Time, (b)
such date and time as the Merger Agreement shall be terminated in accordance with Section 10.1 thereof (the earlier of (a) and (b), the “Expiration Time”) and (c) the liquidation of Acquiror, each Sponsor shall
not (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, file (or participate in the filing of) a registration statement

acquires the right to vote or share in the voting of any shares of Acquiror Common Stock or other equity securities of Acquiror after the date of this Sponsor Agreement (such shares of Acquiror Common Stock or other equity securities of Acquiror,
collectively the “New Securities”), then such New Securities acquired or purchased by such Sponsor shall be subject to the terms of this Sponsor Agreement to the same extent as if they constituted the shares of Acquiror Common Stock
owned by such Sponsor as of the date hereof. 
 Section 1.4 Closing Date Deliverables. On the Closing Date, Sponsor Holdco and the
KVSB Holders (as defined below) shall deliver to Acquiror and the Company a duly executed copy of that certain Amended and Restated Registration Rights Agreement, by and among Acquiror, Sponsor Holdco, the KVSB Holders (as defined therein) and the

to Sponsors. On or before the Closing, the Sponsors shall cause to be surrendered to Acquiror any certificates representing the Sponsor Exchange Shares, duly endorsed for transfer or accompanied by a duly executed stock transfer instrument
reasonably acceptable to the parties hereto. Acquiror shall, as soon as practicable following the Closing, issue to the Sponsors stock certificates representing the shares of Acquiror Post-Merger Class B Common Stock issued in exchange

calculating a quorum and (ii) vote (or cause to be voted), or execute and deliver a written consent (or cause a written consent to be executed and delivered) covering, all of its shares of Acquiror Common Stock: 

(i) in favor of each Transaction Proposal; 

(ii) in any other circumstances upon which a consent or other approval is required under the certificate of incorporation of
Acquiror, as amended from time to time, or otherwise sought with respect to the Merger Agreement or the Transactions, to vote, consent or approve (or cause to be voted, consented or approved) all shares of Acquiror Common Stock held at such time in
favor thereof, including any Anti-Dilution Waiver; 
 (iii) against any Business Combination Proposal or any proposal

voting rights of any class of capital stock of, Acquiror. 
 Each Sponsor hereby agrees that it shall not commit or agree to take any action
inconsistent with the foregoing. 
 (b) Each Sponsor shall comply with, and fully perform all of its obligations, covenants and agreements

 Section 1.7 Further Assurances. Each Sponsor shall execute and deliver, or cause to be delivered, such additional documents,
and take, or cause to be taken, all such further actions and do, or cause to be done, all things reasonably necessary (including under applicable Laws), in each case as reasonably mutually requested by Acquiror and the Company, to effect the
transactions contemplated by this Agreement on the terms and subject to the conditions set forth herein. 
 Section 1.8 No
Inconsistent Agreement. Each Sponsor hereby represents and covenants that such Sponsor has not entered into, and shall not enter into, any agreement that would in any material respect restrict, limit or interfere with the performance of such
Sponsor’s obligations hereunder. 
 Section 1.9 Lock-Up Agreement. Each Sponsor
will deliver to Acquiror, substantially simultaneously with the Effective Time, a duly executed copy of the Lock-Up Agreement, in the form attached as Exhibit A. 

Section 1.10 Sponsor Share Conversion. Sponsor Holdco and each Sponsor hereby (but subject to the consummation of the Merger): (i)
waives (for itself, for its successors, heirs and assigns), to the fullest extent permitted by law and the Amended and Restated Certificate of Incorporation of Acquiror (as may be amended from time to time, the “Certificate of
Incorporation”), the provisions of Section 4.3(b) of the Certificate of Incorporation to have the Acquiror Class B Common Stock convert to Acquiror Class A Common Stock at a ratio of greater than 1.4694498 shares of Acquiror
Class A Common Stock to be issued for each share of Acquiror Class B Common Stock converted and (ii) acknowledges and agrees (for itself, for its successors, heirs and assigns) that the Certificate of Incorporation that will be filed
and in effect immediately after the Effective Time will provide that all shares of Acquiror Class K Common Stock will be reclassified into an aggregate of 3,061,354 shares of Acquiror Post-Merger Class B Common Stock effective upon the
filing of such Certificate of Incorporation. As a result of the foregoing (i) all shares of Acquiror Class B Common Stock would in connection with the Closing convert to an aggregate of 7,347,249 shares of Acquiror Class A Common
Stock, which shares would then be exchanged pursuant to Section 1.5 for the same number of shares of Acquiror Post-Merger Class B Common Stock and (ii) all shares of Acquiror Class K Common Stock would in connection with the
Closing be reclassified into an aggregate of 3,061,354 shares of Acquiror Post-Merger Class B Common Stock, and (iii) following each of (i) and (ii), the Sponsors would hold an aggregate of 10,408,603 shares of Acquiror Post-Merger
Class B Common Stock. The foregoing shall be applicable only in connection with the transactions contemplated by the Merger Agreement and this Agreement (and any shares of Acquiror Class A Common Stock or equity-linked securities issued in
connection with the transactions contemplated by the Merger Agreement and this Agreement) and shall be void and of no force and effect if the Merger Agreement shall be terminated for any reason.

 ARTICLE II 

REPRESENTATIONS AND WARRANTIES 

Section 2.1 Representations and Warranties of the Sponsors. Each Sponsor represents and warrants as of the date hereof to Acquiror
and the Company (solely with respect to itself, himself or herself and not with respect to any other Sponsor) as follows: 
 (a)
Organization; Due Authorization. If such Sponsor is not an individual, it is duly organized, validly existing and in good standing under the Laws of the jurisdiction in which it is incorporated, formed, organized or constituted, and the
execution, delivery and performance of this Sponsor Agreement and the consummation of the transactions contemplated hereby are within such Sponsor’s corporate, limited liability company or organizational powers and have been duly authorized by
all necessary corporate, limited liability company or organizational actions on the part of such Sponsor. If such Sponsor is an individual, such Sponsor has full legal capacity, right and authority to execute and deliver this Sponsor Agreement and
to perform his or her obligations hereunder. This Sponsor Agreement has been duly executed and delivered by such Sponsor and, assuming due authorization, execution and delivery by the other parties to this Sponsor Agreement, this Sponsor Agreement
constitutes a legally valid and binding obligation of such Sponsor, enforceable against such Sponsor in accordance with the terms hereof (except as enforceability may be limited by bankruptcy Laws, other similar Laws affecting creditors’ rights
and general principles of equity affecting the availability of specific performance and other equitable remedies). If this Sponsor Agreement is being executed in a representative or fiduciary capacity, the Person signing this Sponsor Agreement has
full power and authority to enter into this Sponsor Agreement on behalf of the applicable Sponsor. 
 (b) Ownership. Such Sponsor is
the record and beneficial owner (as defined in Rule 13d-3 of the Exchange Act) of, and has good title to, all of such Sponsor’s shares of Acquiror Common Stock, and there exist no Liens or any other
limitation or restriction (including any restriction on the right to vote, sell or otherwise dispose of such shares of Acquiror Common Stock (other than transfer restrictions under the Securities Act)) affecting any such shares of Acquiror Common
Stock, other than Liens pursuant to (i) this Sponsor Agreement, (ii) the Acquiror Governing Documents, (iii) the Merger Agreement, (iv) the Voting Letter Agreement or (v) any applicable securities Laws. Such Sponsor’s
shares of Acquiror Common Stock are the only equity securities in Acquiror owned of record or beneficially by such Sponsor on the date of this Sponsor Agreement, and none of such Sponsor’s shares of Acquiror Common Stock are subject to any
proxy, voting trust or other agreement or arrangement with respect to the voting of such shares of Acquiror Common Stock, except as provided hereunder, under the Voting Letter Agreement. Other than pursuant to the Forward Purchase Agreement and for
shares of Acquiror Class B Common Stock and shares of Acquiror Class K Common Stock, as applicable, such Sponsor does not hold or own any rights to acquire (directly or indirectly) any equity securities of Acquiror or any equity securities
convertible into, or which can be exchanged for, equity securities of Acquiror. 
 (c) No Conflicts. The execution and delivery of
this Sponsor Agreement by such Sponsor does not, and the performance by such Sponsor of his, her or its obligations hereunder will not, (i) if such Sponsor is not an individual, conflict with or result in a violation of the organizational
documents of such Sponsor or (ii) require any consent or approval that has not been given or other action that has not been taken by any Person (including under any Contract binding upon such Sponsor or such Sponsor’s shares of Acquiror
Common Stock), in each case, to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by such Sponsor of its, his or her obligations under this Sponsor Agreement. 

(d) Litigation. There are no Actions pending against such Sponsor, or to the knowledge of such Sponsor threatened against such Sponsor,
before (or, in the case of threatened Actions, that would be before) any arbitrator or any Governmental Authority, which in any manner challenges or seeks to prevent, enjoin or materially delay the performance by such Sponsor of its, his or her
obligations under this Sponsor Agreement. 
 (e) Brokerage Fees. Except for the deferred underwriting commissions and other fees
being held in the Trust Account and for fees payable pursuant to the letter agreement with Evercore Group L.L.C. and Morgan Stanley & Co. LLC dated June 11, 2021 in connection with the PIPE Investment, no broker, finder, investment
banker or other Person is entitled to any brokerage fee, finders’ fee or other commission in connection with the transactions contemplated by the Merger Agreement based upon arrangements made by such Sponsor, for which Acquiror or any of its
Affiliates may become liable. 

  
 5 

 (f) Affiliate Agreements. Except as set forth on Schedule II attached hereto,
neither such Sponsor nor any anyone related by blood, marriage or adoption to such Sponsor or, to the knowledge of such Sponsor, any Person in which such Sponsor has a direct or indirect legal, contractual or beneficial ownership of 5% or greater is
party to, or has any rights with respect to or arising from, any Contract with Acquiror or its Subsidiaries. 
 (g) Acknowledgment.
Such Sponsor understands and acknowledges that each of Acquiror and the Company is entering into the Merger Agreement in reliance upon such Sponsor’s execution and delivery of this Sponsor Agreement.

under this Sponsor Agreement will terminate, without any liability or other obligation on the part of any party hereto to any Person in respect hereof or the transactions contemplated hereby, and no party hereto shall have any claim against another
(and no person shall have any rights against such party), whether under contract, tort or otherwise, with respect to the subject matter hereof; provided, however, that the termination of this Sponsor Agreement shall not relieve any party hereto from

 AGREEMENT 

NOW, THEREFORE, in consideration of the foregoing and the mutual agreements contained herein, and intending to be legally bound hereby, the
parties hereto hereby agree as follows: 
 ARTICLE I 

STOCKHOLDER SUPPORT AGREEMENT; COVENANTS 

Section 1.1 Compliance with Merger Agreement. Each Stockholder hereby acknowledges that it has read the Merger Agreement and this
Agreement and has had the opportunity to consult with its tax and legal advisors. Each Stockholder shall be bound by and comply with Sections 6.5 (Acquisition Proposals) and 11.12 (Publicity) of the Merger Agreement (and any relevant
definitions contained in any such Sections) to the same extent as such provisions apply to the Company as if such Stockholder was an original signatory to the Merger Agreement with respect to such provisions. 

Section 1.2 No Transfer. During the period commencing on the date hereof and ending on the earlier to occur of (a) the
Effective Time, and (b) such date and time as the Merger Agreement shall be terminated in accordance with Section 10.1 thereof (the earlier of clause (a) and (b) being the “Expiration Time”), except as expressly
contemplated by the Merger Agreement or with the prior written consent of Acquiror, each Stockholder shall not (i) sell, offer to sell, contract or agree to sell, transfer (including by operation of law), hypothecate, pledge, grant any option
to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, any Subject Securities or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of
ownership of any Subject Securities (clauses (i) and (ii) collectively, a “Transfer”) or (iii) take any action in furtherance of any of the matters described in the foregoing clauses (i) and (ii); provided,
however, that the foregoing shall not apply to (x) any Transfer to a Stockholder’s Affiliates, provided that such transferee agrees in a written agreement to be bound by this Agreement prior to the occurrence of such Transfer or
(y) any other Stockholder that is party to this Agreement. 
 Section 1.3 New Shares. In the event that, during the period
commencing on the date hereof and ending at the Expiration Time, (a) any Subject Securities are issued to a Stockholder after the date of this Agreement pursuant to any stock dividend, stock split, recapitalization, reclassification,
combination or exchange of Subject Securities or otherwise, (b) a Stockholder purchases or otherwise acquires beneficial ownership of any Subject Securities or (c) a Stockholder acquires the right to vote or share in the voting of any
Subject Securities (collectively the “New Securities”), then such New Securities acquired or purchased by such Stockholder shall be subject to the terms of this Agreement to the same extent as if they constituted the Subject
Securities owned by such Stockholder as of the date hereof. 
 Section 1.4 Stockholder Agreements. Hereafter until the
Expiration Time, each Stockholder hereby unconditionally and irrevocably agrees that, at any meeting of the stockholders of the Company (in each case, including any adjournment or postponement thereof), and in any action by written consent of the
stockholders of Company, requested by the Board of Directors of the Company or otherwise undertaken as contemplated by the Transactions, including in the form attached as Exhibit A (which written consent shall be delivered as promptly as
reasonably practicable, and in any event within three (3) Business Days, after the Registration Statement (as contemplated by the Merger Agreement) has been declared effective under the Securities Act and has been delivered or otherwise made
available to the stockholders of Acquiror and the stockholders of the Company), such Stockholder shall, if a meeting is held, appear at the meeting, in person or by proxy, or otherwise cause its Subject Securities to be counted as present thereat
for purposes of establishing a quorum, and such Stockholder shall vote or provide consent (or cause to be voted or consented), in person or by proxy, all of its Subject Securities: 

(a) to approve and adopt the Merger Agreement and the Transactions; 

(b) to authorize and approve, with respect to any and all shares of Company Preferred Stock held by such Stockholder, the
conversion of all outstanding shares of Company Preferred Stock into Company Common Stock as of immediately prior to the Effective Time in accordance with Article VI, Section 6.2(a)(ii) of the certificate of incorporation of the Company; 

  
 2 

 (c) in any other circumstances upon which a consent or other approval is
required under the certificate of incorporation or bylaws of the Company or the Investment Agreements, or a consent or other approval is otherwise sought with respect to the Merger Agreement or the Transactions, to vote, consent or approve (or cause
to be voted, consented or approved) all of such Stockholder’s Subject Securities held at such time in favor thereof; 

(d) against and withhold consent with respect to any Acquisition Proposal; and 

(e) against any and all other proposals that could reasonably be expected to delay or impair the ability of the Company to
consummate the Transactions. 
 Each Stockholder hereby agrees that it shall not commit or agree to take any action inconsistent with the
foregoing. 
 Section 1.5 Proxy. 

(a) Without limiting any other rights or remedies of the Company, each Stockholder hereby irrevocably appoints the Company or any individual
designated by the Company as the Stockholder’s agent, attorney-in-fact and proxy (with full power of substitution and resubstituting), for and in the name, place
and stead of the Stockholder, to attend on behalf of the Stockholder any meeting of the stockholders of the Company with respect to the matters described in Section 1.4, to include the Subject Securities in any computation
for purposes of establishing a quorum at any such meeting of the stockholders of the Company, to vote (or cause to be voted) the Subject Securities or consent (or withhold consent) with respect to any of the matters described in
Section 1.4 in connection with any meeting of the stockholders of the Company or any action by written consent by the stockholders of the Company (including the Written Consent), in each case, in the event that the
Stockholder fails to perform or otherwise comply with the covenants, agreements or obligations set forth in Section 1.4. 

(b) The proxy granted by the Stockholder pursuant to Section 1.5(a) is coupled with an interest sufficient in Law to
support an irrevocable proxy and is granted in consideration for the Company entering into the Merger Agreement and agreeing to consummate the transactions contemplated thereby. The proxy granted by the Stockholder pursuant to
Section 1.5(a) is also a durable proxy and shall survive the bankruptcy, dissolution, death, incapacity or other inability to act by the Stockholder and shall revoke any and all prior proxies granted by the Stockholder with
respect to the Subject Securities. The vote or consent of the proxyholder in accordance with Section 1.5(a) and with respect to the matters in Section 1.4 shall control in the event of any conflict
between such vote or consent by the proxyholder of the Subject Securities and a vote or consent by the Stockholder of the Subject Securities (or any other Person with the power to vote the Subject Securities) with respect to the matters in
Section 1.4. The proxyholder may not exercise the proxy granted pursuant to Section 1.5(a) on any matter except those provided in Section 1.4. For the avoidance of doubt,
the Stockholder may vote the Subject Securities on all other matters, subject to, for the avoidance of doubt, the other applicable covenants, agreements and obligations set forth in this Agreement. 

Section 1.6 No Challenges. Each Stockholder agrees not to commence, join in, facilitate, assist or encourage, and agrees to take
all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Acquiror, Merger Sub, the Company or any of their respective successors or directors (a) challenging the validity of,
or seeking to enjoin the operation of, any provision of this Agreement or (b) alleging a breach of any fiduciary duty of any person in connection with the evaluation, negotiation or entry into this Agreement, the Merger Agreement or the
Transactions (including the Pre-Closing Restructuring).  

  
 3 

 Section 1.7 Appraisal Rights. Each Stockholder hereby waives and agrees not to
exercise any rights of appraisal or rights to dissent from the transactions contemplated by the Merger Agreement that he, she or it may have with respect to the Subject Securities under applicable Law. 

Section 1.8 Affiliate Agreements. Each Stockholder hereby agrees and consents to the termination of each Contract between such
Stockholder or its Affiliates, on the one hand, and the Company or its Affiliates, on the other hand, providing for management rights, notice rights, information or examination rights or other similar rights in such Stockholder’s capacity as a
securityholder of the Company, including all Affiliate Agreements set forth on Schedule II attached hereto to which such Stockholder is party, in each case effective as of the Effective Time and without any further liability or obligation to
the Company, the Company’s Subsidiaries or Acquiror. 
 Section 1.9 Registration Rights Agreement. Each of the Stockholders
that is a Major Company Stockholder will deliver, substantially simultaneously with the Effective Time, a duly executed copy of the Amended and Restated Registration Rights Agreement, by and among Acquiror, the KVSB Holders (as defined therein) and
the Target Holders (as defined therein) and, in substantially in the form attached as Exhibit C to the Merger Agreement. 

Section 1.10 Further Assurances. Each Stockholder shall execute and deliver, or cause to be delivered, such additional documents,
and take, or cause to be taken, all such further actions and do, or cause to be done, all things reasonably necessary (including under applicable Laws), in each case as reasonably mutually requested by Acquiror and the Company, to effect the
transactions contemplated by this Agreement on the terms and subject to the conditions set forth herein. 
 Section 1.11 No
Inconsistent Agreement. Each Stockholder hereby represents and covenants that such Stockholder has not entered into, and shall not enter into, any agreement that would in any material respect restrict, limit or interfere with the performance of
such Stockholder’s obligations hereunder. 
 Section 1.12 Consent to Disclosure. Each Stockholder hereby consents to the
publication and disclosure in the Registration Statement (and, as and to the extent otherwise required by applicable securities Laws or the SEC or any other securities authorities, any other documents or communications provided by Acquiror or the
Company to any Governmental Authority or to securityholders of Acquiror) of such Stockholder’s identity and beneficial ownership of Subject Securities and the nature of such Stockholder’s commitments, arrangements and understandings under
and relating to this Agreement and, if deemed appropriate by Acquiror or the Company, a copy of this Agreement. Each Stockholder will promptly provide any information reasonably requested by Acquiror or the Company that is necessary for any
regulatory application or filing made or approval sought in connection with the Transactions (including filings with the SEC).

 ARTICLE II 

REPRESENTATIONS AND WARRANTIES 

Section 2.1 Representations and Warranties of the Stockholders. Each Stockholder represents and warrants as of the date hereof to
Acquiror and the Company (solely with respect to itself, himself or herself and not with respect to any other Stockholder) as follows: 

(a) Organization; Due Authorization. If such Stockholder is not an individual, it is duly organized, validly existing
and in good standing under the Laws of the jurisdiction in which it is incorporated, formed, organized or constituted, and the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby are
within such Stockholder’s corporate, limited liability company or organizational powers and have been duly authorized by all necessary corporate, limited liability company or organizational actions on the part of such Stockholder. If such
Stockholder is an individual, such Stockholder has full legal capacity, right and authority to execute and deliver this Agreement and to perform his or her obligations hereunder. This Agreement has been duly executed and delivered by such
Stockholder and, assuming due authorization, execution and delivery by the other parties to this Agreement, this Agreement constitutes a legally valid and binding obligation of such Stockholder, enforceable against such Stockholder in accordance
with the terms hereof (except as enforceability may be limited by bankruptcy Laws, other similar Laws affecting creditors’ rights and general principles of equity affecting the availability of specific performance and other equitable remedies).
If this Agreement is being executed in a representative or fiduciary capacity, the Person signing this Agreement has full power and authority to enter into this Agreement on behalf of the applicable Stockholder. 

(b) Ownership. Such Stockholder is the record and beneficial owner (as defined in Rule
13d-3 of the Exchange Act) of, and has good title to, all of such Stockholder’s Subject Securities, and there exist no Liens or any other limitation or restriction (including any restriction on the right
to vote, sell or otherwise dispose of such Subject Securities (other than transfer restrictions under the Securities Act)) affecting any such Subject Securities, other than Liens pursuant to (i) this Agreement, (ii) the certificate of
incorporation of the Company, (iii) the Investment Agreements, (iv) the Merger Agreement, or (v) any applicable securities Laws. Such Stockholder’s Subject Securities are the only equity securities in the Company owned of record
or beneficially by such Stockholder on the date of this Agreement, and none of such Stockholder’s Subject Securities are subject to any proxy, voting trust or other agreement or arrangement with respect to the voting of such Subject Securities,
except as provided hereunder and under the certificate of incorporation of the Company and the Investment Agreements. Such Stockholder does not hold or own any rights to acquire (directly or indirectly) any equity securities of the Company or any
equity securities convertible into, or which can be exchanged for, equity securities of the Company. 
 (c) No
Conflicts. The execution and delivery of this Agreement by such Stockholder does not, and the performance by such Stockholder of his, her or its obligations hereunder will not, (i) if such Stockholder is not an individual, conflict with or
result in a violation of the organizational documents of such Stockholder or (ii) require any consent or approval that has not been given or other action that has not been taken by any Person (including under any Contract binding upon such
Stockholder or such Stockholder’s Subject Securities) to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by such Stockholder of its, his or her obligations under this Agreement. 

(d) Litigation. There are no Actions pending against such Stockholder, or to the knowledge of such Stockholder
threatened against such Stockholder, before (or, in the case of threatened Actions, that would be before) any arbitrator or any Governmental Authority, which in any manner challenges or seeks to prevent, enjoin or materially delay the performance by
such Stockholder of its, his or her obligations under this Agreement. 

  
 5 

 (e) Adequate Information. Such Stockholder has been furnished or
given access to adequate information concerning the business and financial condition of Acquiror and the Company to make an informed decision regarding this Agreement and the Transactions and has independently and without reliance upon Acquiror or
the Company and based on such information as such Stockholder has deemed appropriate, made its own analysis and decision to enter into this Agreement. Such Stockholder acknowledges that Acquiror and the Company have not made and do not make any
representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement. Such Stockholder acknowledges that the agreements contained herein with respect to the Subject Securities held by such
Stockholder are irrevocable and result in the waiver of any right of the undersigned to demand appraisal in connection with the Merger under Section 262 of the General Corporation Law of the State of Delaware or any other Law. 

(f) Brokerage Fees. No broker, finder, investment banker or other Person is entitled to any brokerage fee, finders’
fee or other commission in connection with the transactions contemplated by the Merger Agreement based upon arrangements made by such Stockholder, for which the Company or any of its Affiliates may become liable. 

(g) Acknowledgment. Such Stockholder understands and acknowledges that each of Acquiror and the Company is entering into
the Merger Agreement in reliance upon such Stockholder’s execution and delivery of this Agreement. 
 ARTICLE III 

MISCELLANEOUS 

Section 3.1 Termination. This Agreement and all of its provisions shall terminate and be of no further force or effect upon the
earlier of (a) the Expiration Time and (b) as to each Stockholder, the written agreement of Acquiror, the Company and such Stockholder. Upon such termination of this Agreement, all obligations of the parties under this Agreement will
terminate, without any liability or other obligation on the part of any party hereto to any Person in respect hereof or the transactions contemplated hereby, and no party hereto shall have any claim against another (and no person shall have any
rights against such party), whether under contract, tort or otherwise, with respect to the subject matter hereof; provided, however, that the termination of this Agreement shall not relieve any party hereto from liability arising in
respect of any willful breach of this Agreement prior to such termination. This ARTICLE III shall survive the termination of this Agreement. 

Section 3.2 Miscellaneous. Sections 11.7 (Governing Law), 11.13 (Severability) 11.14 (Jurisdiction; Waiver of
Jury Trial) and 11.15 (Enforcement) of the Merger Agreement are incorporated herein by reference and shall apply to this Agreement, mutatis mutandis. 

Section 3.3 Assignment. This Agreement and all of the provisions hereof will be binding upon and inure to the benefit of the
parties hereto and their respective heirs, successors and permitted assigns. Except by a Stockholder in connection with a transfer of Subject Securities permitted by Section 2.1 herein, neither this Agreement nor any of the
rights, interests or obligations hereunder will be assigned (including by operation of Law) without the prior written consent of the parties hereto. 

Section 3.4 Amendment; Waiver. This Agreement may not be amended, changed, supplemented, waived or otherwise modified or
terminated, except upon the execution and delivery of a written agreement executed by Acquiror, the Stockholders and the Company.
