meanings ascribed to such terms in the Merger Agreement. As used herein, the term “Section” shall, unless otherwise specified,
refer to the specified Section of this Support Agreement.

 

The Stockholder is currently the record owner
of the shares of Company Preferred Stock and Company Common Stock (the “Stockholder Shares”) set forth on such Stockholder’s
signature page hereto, and together with the Stockholder Shares held by the other Stockholders party to this Support Agreement, such shares
represent the voting power of the Company’s security holders necessary to approve the Transactions.

as present thereat for the purpose of establishing a quorum;

to time (the “Company Charter”);

 

		d.	vote (or execute and return an action by written consent), or cause to be voted at the Meeting (or validly

in a breach of any covenant, representation or warranty or other obligation or agreement of the Company under the Merger Agreement, or
(z) result in a breach of any covenant, representation or warranty or other obligation or agreement of the Stockholder contained in this
Support Agreement; and

 

		e.	in any other circumstances upon which a consent or other approval is required under the Company’s Organizational Documents or

consent or approve (or cause to be voted, consented or approved) all of such Stockholder’s Stockholder Shares held at such time
in favor thereof.

 

		2.	No Challenge. The 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,

employment agreements or arrangements between such Stockholder and the Company or any Subsidiary thereof, which shall survive the Closing
in accordance with their terms, and (ii) any indemnification, advancement of expenses and exculpation rights of any Stockholder or any

		8.	Damages; Remedies. The Stockholder hereby agrees and acknowledges that (i) Parent and Company shall
each would be irreparably injured in the event of a breach by the Stockholder of its obligations under this Support Agreement, (ii) monetary
damages would not be an adequate remedy for such breach, and (iii) the non-breaching party shall be entitled to injunctive relief, in

    3

     

    

 

		10.	During the period commencing on the date hereof and ending on the earlier to occur of (i) the Effective
Time, and (ii) such date and time as the Merger Agreement shall be terminated in accordance with Section 9.1 thereof, in the event that,

Representations and Warranties of Sponsor. Sponsor represents and warrants as of the date
hereof to Parent and the Company as follows:

 

(a) Organization; Due Authorization.
Sponsor 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 its corporate limited liability company or organizational powers and has been duly authorized by all necessary
corporate, limited liability company or organizational actions on the part of Sponsor. This Sponsor Agreement has been duly executed
and delivered by 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 Sponsor, enforceable against 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 Sponsor.

 

    	 	3	 

     

    

 

(b) Ownership. Sponsor
is the record and “beneficial owner” (within the meaning of Rule 13d-3 under the Exchange Act) of, and has good title to,
Sponsor’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 or any other limitation or restriction pursuant to (i) this Sponsor Agreement, (ii) the
Parent Organizational Documents, (iii) the Merger Agreement, (iv) the Insider Letter, (v) any applicable securities laws. Sponsor’s
Subject Securities are the only equity securities in Parent owned of record or beneficially by Sponsor on the date of this Sponsor Agreement,
and none of Sponsor’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 Insider Letter, Merger Agreement and organizational
documents of Sponsor. Other than the warrants of Parent held by Sponsor, Sponsor does not hold or own any rights to acquire (directly
or indirectly) any equity securities of Parent or any equity securities convertible into, or which can be exchanged for, equity securities
of Parent.

 

(c)  
No Conflicts. The execution and delivery of this Sponsor Agreement by Sponsor does not, and the performance by Sponsor of
his, her or its obligations hereunder will not, (i) conflict with or result in a violation of the organizational documents of 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 Sponsor or Sponsor’s Subject Securities), in each case, to the extent such consent, approval or other
action would prevent, enjoin or materially delay the performance by Sponsor of its obligations under this Sponsor Agreement.

 

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

 

(e)  
Brokerage Fees. Except as described on Section 5.21 of the Parent Disclosure Letter, 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 Sponsor, for which Parent or any of its Affiliates may become liable.

 

(f)   
Affiliate Arrangements. Except as set forth on Schedule 1 attached hereto, or as otherwise disclosed in the Parent
SEC Reports filed with the SEC prior to the date of this Sponsor Agreement, neither Sponsor nor any of the present or former directors,
officers, employees, stockholders or Affiliates of Sponsor (or an immediate family member of any of the foregoing) is party to, or has
any rights with respect to or arising from, any Contract with Parent.
