the Closing shall be unvested and shall be subject to the vesting and forfeiture provisions set forth in this Section 1.9. 

  
 4 

 (b) Vesting of Shares at Closing. 70% of the unvested Founder Shares owned by the
Sponsors (or their respective Affiliates) as of the Closing shall vest (and shall not be subject to forfeiture) at the Closing. 
 (c)
Performance Vesting Shares. 
 (i) 15% of the unvested Founder Shares owned by the Sponsors (or their respective
Affiliates) as of the Closing shall vest (and shall not be subject to forfeiture) upon the occurrence of Triggering Event I (the “$12 Founder Shares”). If Triggering Event I does not occur on or prior to the fifth anniversary of the
Closing Date, the Founder Shares that were eligible to vest pursuant to this Section 1.9(c)(i) shall not vest, and shall be forfeited as provided in Section 1.9(c)(iii). 

(ii) 15% of the unvested Founder Shares owned by the Sponsors (or their respective Affiliates) as of the Closing shall vest
(and shall not be subject to forfeiture) upon the occurrence of Triggering Event II (the “$15 Founder Shares”). If Triggering Event II does not occur on or prior to the fifth anniversary of the Closing Date, the Founder Shares that

Section 1.9(c)(ii) shall be deemed transferred by the forfeiting holder to the Acquiror and shall be cancelled by Acquiror and cease to exist. 

(d) Acquiror Sale. In the event that there is a Company Sale after the Closing but on or prior to the fifth anniversary of the
Closing Date that will result in the holders of Acquiror Common Stock receiving a Company Sale Price equal to or in excess of the applicable price per share attributable to any Triggering Event, then immediately prior to the consummation of the
Company Sale any such Triggering Event that has not previously occurred shall be and the related vesting conditions shall also be deemed to have occurred and the holders of such Founder Shares shall be eligible to participate in such Company Sale.
For avoidance of doubt, assuming no prior Triggering Events have occurred, in the case of clause (y): (i) if the Company Sale Price for acquisition of the Acquiror Common Stock is greater than or equal to $12.00 per share of Acquiror Common Stock
but less than $15.00 per share of Acquiror Common Stock, the $12 Founder Shares shall be deemed to have fully vested (and the $15 Founder Shares shall be deemed forfeited and shall be cancelled by Acquiror); (ii) if the Company Sale Price for
acquisition of the Acquiror Common Stock is greater than or equal to $15.00 per share of Acquiror Common Stock, the $12 Founder Shares and the $15 Founder Shares shall be deemed to have vested; provided, however, that if
the Company Sale Price for acquisition of the Acquiror Common Stock is less than $12.00 per share of Acquiror Common Stock, then no Founder Shares shall be deemed to have vested and all such Founder Shares shall be deemed forfeited and shall be
cancelled by Acquiror. 

  
 5 

 (e) Subject to the limitations contemplated herein, the Sponsors shall have all of the
rights of a stockholder of the Acquiror with respect to the Founder Shares, including the right to receive dividends and/or distributions made to the holders of Acquiror Common Stock and to voting rights generally granted to holders of Acquiror
Common Stock; provided, however, that the unvested Founder Shares shall not entitle the holder thereof to consideration in connection with any sale or other transaction and may not be offered, sold, transferred, redeemed, assigned,
pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) by the Sponsors, as the case may be, or be subject to execution, attachment or similar process, and shall bear a customary legend with respect to
such transfer restrictions. Any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of such unvested Founder Shares shall be null and void. 

(f) If, and as often as, there are any changes in the Acquiror or the Founder Shares by way of stock split, stock dividend, combination or
reclassification, or through merger, consolidation, reorganization, recapitalization or business combination, or by any other means, equitable adjustment shall be made to the provisions of this Sponsor Agreement as may be required so that the
rights, privileges, duties and obligations hereunder shall continue with respect to Acquiror, Acquiror’s successor or the surviving entity of such transaction and the Founder Warrants, each as so changed. Each of the Sponsors will promptly
inform the Company of any elections made by such Sponsor under Section 83(b) of the Internal Revenue Code in connection with the Closing with respect to Founder Shares held by such Sponsor. 

(g) For purposes of this Section 1.9: 

(i) “Company Sale” means (which, for the avoidance of doubt, shall not include the Transactions): (x) any
transaction or series of related transactions that results in any Person or “group” (within the meaning of Section 13(d)(3) of the Exchange Act) acquiring Equity Securities that represent more than 50% of the total voting power of the

and its Subsidiaries on a consolidated basis, in each case other than a transaction or series of related transactions which results in at least 50% of the combined voting power of the then outstanding voting securities of Acquiror (or any successor
to Acquiror) immediately following the closing of such transaction (or series of related transactions) being beneficially owned, directly or indirectly, by individuals and entities (or Affiliates of such individuals and entities) who were the
beneficial owners, respectively, of Equity Securities representing more than 50% of the total voting power of the then outstanding voting securities of Acquiror immediately prior to such transaction (or series of related transactions). 

(ii) “Company Sale Price” means the price per share for Acquiror Common Stock in a Company Sale. If and to
the extent the price paid per share includes any escrows, holdbacks, deferred purchase price, earnouts or other contingent consideration, Acquiror’s Board of Directors shall determine the price paid per share of Acquiror Common Stock in such
Company Sale in good faith. If and to the extent the price is payable in whole or in part with consideration other than cash, the price for such non-cash consideration shall be determined as follows:
(x) with respect to any securities: (A) the average of the closing prices of the sales of the securities on all securities exchanges on which the securities may at the time 

  
 6 

 
be listed averaged over a period of 21 days consisting of the day as of which such value is being determined and the 20 consecutive business days prior to such day or (B) if the information
in (A) is not practically available, the value of each such security shall be equal to the fair value thereof as of the date of valuation as determined by an independent, nationally recognized investment banking firm to be appointed with the
mutual approval of Acquiror, the Company and the HEC Representative on the basis of an orderly sale to a willing, unaffiliated buyer in an arm’s-length transaction, taking into account all factors
determinative of value as the investment banking firm determines relevant (and, in the case of clause (A) or (B), reduced by the amount of any transfer Taxes payable in connection with such sale) and (y) with respect to any other non-cash assets, the fair value thereof as of the date of valuation as determined by an independent, nationally recognized investment banking firm to be appointed with the mutual approval of Acquiror and HEC on the
basis of an orderly sale to a willing, unaffiliated buyer in an arm’s-length transaction, taking into account all factors determinative of value as the investment banking firm determines relevant (and
reduced by the amount of any transfer Taxes payable in connection with such sale). 
 (iii) “Earn Out
Period” means the date that is five (5) years following the Closing Date. 
 (iv) “Triggering Event
I” means the date following the Closing but prior to the expiration of the Earn Out Period, on which the per-share price on Nasdaq (as reported by Bloomberg) of the Acquiror Common Stock is greater
than or equal to $12.00. 
 (v) “Triggering Event II” means the date following the Closing but prior to the
expiration of the Earn Out Period, on which the per-share price on Nasdaq (as reported by Bloomberg) of the Acquiror Common Stock is greater than or equal to $15.00.

further consideration, each 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 and the
transactions contemplated hereby. Each Stockholder further 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 action or claim, derivative or otherwise, against

contemplated hereby and thereby.

or otherwise, except by an instrument in writing signed by Acquiror, the Company and the applicable Stockholder. 
 10. Waiver. No
failure or delay by any Party 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 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 to any such waiver shall be valid

Neither this Agreement nor any of the rights, interests or obligations hereunder shall (a) be assigned by any of the Stockholders in whole or in part (whether by operation of Law or otherwise) without the prior written consent of Acquiror and
the Company or (b) be assigned by Acquiror or the Company in whole or in part (whether by operation of law or otherwise) without the prior written consent of (i) the Company or Acquiror, respectively, and (ii) the applicable
Stockholder. 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 and their respective successors and permitted assigns. 

17. Enforcement. The rights and remedies of the Parties shall be cumulative with and not exclusive of any other remedy conferred hereby.
The Parties agree that irreparable damage would occur and that the Parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement,
including each Stockholder’s obligations to vote its Covered Shares as provided in this Agreement, in the Court of Chancery of the State of Delaware or, if under applicable law exclusive jurisdiction over such matter is vested in the federal
courts, any state or federal court located in the State of Delaware, without proof of actual damages or otherwise (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in
addition to any other remedy to which they are entitled at law or in equity. 
 18. Severability. If any term or other provision of
this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void, unenforceable or against its regulatory policy, the remainder of the terms and provisions of this Agreement shall remain in full force and effect and
shall in no way be affected, impaired or invalidated, so long as the economic and legal substance of the transactions contemplated hereby, taken as a whole, are not affected in a manner materially adverse to any Party. Upon such a determination, the
Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally
contemplated to the fullest extent possible.

 19. Counterparts. This Agreement may be executed in one or more counterparts, all of
which shall be considered one and the same agreement, it being understood that each Party need not sign the same counterpart. This Agreement shall become effective when each Party shall have received a counterpart hereof signed by all of the other
Parties. Signatures delivered electronically or by facsimile shall be deemed to be original signatures. 
 20. Interpretation and
Construction. The words “hereof,” “herein” and “hereunder” and words of like import used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The
descriptive headings used herein are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of this Agreement. References to Sections are to Sections of this Agreement unless
otherwise specified. Any singular term in this Agreement shall be deemed to include the plural, and any plural term the singular. The definitions contained in this Agreement are applicable to the masculine as well as to the feminine and neuter
genders of such term. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation,” whether or not they are in fact
followed by those words or words of like import. “Writing,” “written” and comparable terms refer to printing, typing and other means of reproducing words (including electronic media) in a visible form. References to any statute
shall be deemed to refer to such statute and to any rules or regulations promulgated thereunder. References to any person include the successors and permitted assigns of that person. References from or through any date mean, unless otherwise
specified, from and including such date or through and including such date, respectively. In the event an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the Parties, and no
presumption or burden of proof will arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement. 

21. Capacity as a Stockholder or Proxy holder. Notwithstanding anything herein to the contrary, the Stockholder or proxy holder signs
this Agreement solely in the Stockholder’s or proxy holder’s capacity as a stockholder or proxy holder of the Company, and not in any other capacity and this Agreement shall not limit, prevent or otherwise affect the actions of the
Stockholder, proxy holder or any Affiliate or Representative of the Stockholder or proxyholder, or any of their respective Affiliates in his or her capacity, if applicable, as an officer or director of the Company (or any Subsidiary of the Company)
or any other Person, including in the exercise of his or her fiduciary duties as a director or officer of the Company or any Subsidiary of the Company. No Stockholder shall be liable or responsible for any breach, default, or violation of any
representation, warranty, covenant or agreement hereunder by any other Stockholder that is also a Party and each Stockholder shall solely be required to perform its obligations hereunder in its individual capacity.
