AGREEMENT


 


NOW,
THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below
and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending
to be legally bound, do hereby agree as follows:


 


1.
Company Stockholder Consent and Related Matters.


 


(a)
Subject to the earlier termination of the Agreement in accordance with Section 4, as promptly as reasonably practicable (and in
any event within one (1) Business Day) following the time at which the Registration Statement / Proxy Statement is declared effective
under the Securities Act, the Stockholder shall duly execute and deliver to the Company and Parent an irrevocable written consent (the
“Company Stockholder Written Consent”) in accordance with the DGCL and the Company’s Governing Documents, approving
and adopting the Merger Agreement, the Transaction Documents to which the Company is or will be a party, and the transactions contemplated
thereunder (including the Merger), the amendment of the Certificate of Incorporation of the Company in the form attached thereto as Schedule
B hereto (the “Amendment”), and the matters, actions and proposals contemplated by Section 5.14(b) of the Merger
Agreement as and to the extent provided herein. Without limiting the generality of the foregoing in this Section 1(a), prior to
the Closing, the Stockholder shall vote (or cause to be voted) the Subject Shares, at any meeting of the Company Stockholders, however
called, and in any action by written consent of Company Stockholders, (1) in favor of the adoption of the Merger Agreement and the approval
of the Merger, and (2) against and withhold consent with respect to (A) any Company Acquisition Proposal or (B) any other matter, action
or proposal that would reasonably be expected to result in (x) a breach of any of the Company’s covenants, agreements or obligations
under the Merger Agreement or (y) any of the conditions to the Closing set forth in Sections 6.1 or 6.2 of the Merger Agreement not being
satisfied.


 




    	 



    	 



    

 


(b)
Without limiting any other rights or remedies of Parent, the Stockholder hereby irrevocably appoints Parent or any individual designated
by Parent 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 Company Stockholders with
respect to the matters described in Section 1(a), to include the Subject Shares in any computation for purposes of establishing
a quorum at any such meeting of the Company Stockholders, to vote (or cause to be voted) the Subject Shares or consent (or withhold consent)
with respect to any of the matters described in Section 1(a) in connection with any meeting of the Company Stockholders or any
action by written consent by the Company Stockholders (including the Company Stockholder 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(a).


 


(c)
The proxy granted by the Stockholder pursuant to Section 1(b) is coupled with an interest sufficient in law to support an irrevocable
proxy and is granted in consideration for Parent entering into the Merger Agreement and agreeing to consummate the transactions contemplated
thereby. The proxy granted by the Stockholder pursuant to Section 1(b) 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 Shares. The vote or consent of the proxyholder in accordance with Section 1(b) and with
respect to the matters described in Section 1(b) shall control in the event of any conflict between such vote or consent by the
proxyholder of the Subject Shares and a vote or consent by the Stockholder of the Subject Shares (or any other Person with the power
to vote or provide consent with respect to the Subject Shares) with respect to the matters described in Section 1(b). The proxyholder
may not exercise the proxy granted pursuant to Section 1(b) on any matter except for those matters described in Section 1(b).


 


(d)
Except as expressly set forth herein, at any time prior to the Termination Date, the Stockholder shall not enter into any agreement,
understanding or arrangement (whether written or oral) with any Person to vote or give instructions in any manner inconsistent with this
Section 1, other than customary prime broker arrangements. Any such vote shall be cast, or consent shall be given, in accordance
with such procedures relating thereto so as to ensure that it is duly counted for purposes of determining that a quorum is present and
for purposes of recording the results of such vote or consent.

2.
Other Covenants and Agreements.


 


(a)
The Stockholder hereby agrees that, notwithstanding anything to the contrary in any such agreement, upon such termination neither the
Company nor any of its Affiliates (including, from and after the Effective Time, Parent and its Affiliates) shall have any further obligations

execute and deliver all additional agreements, documents or instruments, take, or cause to be taken, all actions and provide, or cause
to be provided, all additional information or other materials as may be necessary or reasonably advisable, in each case, as reasonably
determined by Parent, in connection with, or otherwise in furtherance of, the consummation of the transactions contemplated by the Merger
Agreement or this Agreement.


 


(b)
The Stockholder shall be bound by and subject to (i) Section 5.4(a) (Public Announcements) of the Merger Agreement to the same extent
as such provisions apply to the parties of the Merger Agreement, as if the Stockholder is directly party thereto, and (ii) the first
sentence of Section 5.7(a) (Exclusive Dealing) and Section 8.17 (Trust Account Waiver) of the Merger Agreement to the same extent as
such provisions apply to the Company, as if the Stockholder is directly party thereto.


 


(c)
The Stockholder acknowledges and agrees that Parent is entering into the Merger Agreement in reliance upon the Stockholder entering into
this Agreement and agreeing to be bound by, and perform, or otherwise comply with, as applicable, the agreements, covenants and obligations
contained in this Agreement.


 


3.
No Transfers. Except as expressly contemplated by the Merger Agreement or with the prior written consent of Parent (such consent
to be given or withheld in its sole discretion), from and after the date hereof through the termination of this Agreement pursuant to
Section 4 hereof, the Stockholder agrees not to (a) Transfer any of the Subject Shares, (b) enter into (i) any option, warrant,
purchase right, or other Contract that would (either alone or in connection with one or more events or developments (including the satisfaction
or waiver of any conditions precedent)) require the Stockholder to Transfer the Subject Shares or (ii) any voting trust, proxy or other
Contract with respect to the voting or Transfer of the Subject Shares other than customary prime broker arrangements, or (c) take any
actions in furtherance of any of the matters described in the foregoing clauses (a) or (b). For purposes of this Agreement, “Transfer”
means any, direct or indirect, sale, transfer, assignment, pledge, mortgage, exchange, hypothecation, grant of a security interest in
or disposition or encumbrance of an interest (whether with or without consideration, whether voluntarily or involuntarily or by operation
of law or otherwise).


 


4.
Termination. This Agreement shall automatically terminate, without any notice or other action by any Party, and be void ab initio
upon the earlier of (a) the Effective Time; and (b) the termination of the Merger Agreement in accordance with its terms. Upon termination
of this Agreement as provided in the immediately preceding sentence, none of the Parties shall have any further obligations or Liabilities
under, or with respect to, this Agreement. Notwithstanding the foregoing or anything to the contrary in this Agreement, (i) the termination
of this Agreement pursuant to Section 4(b) shall not affect any Liability on the part of any Party for a Willful Breach of any
covenant or agreement set forth in this Agreement prior to such termination, or in the case of Fraud and (ii) each of Section 2(b)(ii)
(solely to the extent it relates to Section 8.17 (Trust Account Waiver) of the Merger Agreement), Section 7, Section 8,
and Sections 10 to 23 of this Agreement shall remain in full force and effect and survive any termination of this Agreement.

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, as would not reasonably be expected to prevent or materially delay or impair the Stockholder’s
ability to perform its obligations hereunder or to consummate the transactions contemplated hereby.


 


(f)
As of the date of this Agreement, there is no action, proceeding or investigation pending against the Stockholder or, to the knowledge

11.
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. 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.


 


12.
Entire Agreement. This Agreement and the agreements referenced herein constitute the entire agreement and understanding of the
Parties in respect of the subject matter hereof and supersede all prior understandings, agreements or representations by or among the
Parties to the extent they relate in any way to the subject matter hereof.


 


13.
No Third-Party Beneficiaries. The Stockholder hereby agrees that (a) 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, (b) this Agreement is being entered
into in order to induce the Parent to execute and deliver the Merger Agreement and without the representations, warranties, covenants
and agreements of the Stockholder hereunder, the Parent would not enter into the Merger Agreement, and (c) 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 Proceeding 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.


 


14.
Amendment. 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, the Company and the Stockholder.


 


15.
Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall (a) be assigned by the Stockholder,
in whole or in part (whether by operation of Law or otherwise), without the prior written consent of Parent and the Company or (b) be
assigned by Parent or the Company, in whole or in part (whether by operation of law or otherwise), without the prior written consent
of the Company (in the case of an attempted assignment by Parent) or Parent (in the case of an attempted assignment by the Company).
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.


 


16.
Other Remedies; Specific Performance. The Parties agree that irreparable damage (for which monetary damages, even if available,
would not be an adequate remedy) 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 specific performance, an injunction or injunctions, or other equitable relief to prevent
breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, 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. Each Party acknowledges and
agrees that the right of specific enforcement is an integral part of the transactions contemplated hereby and that, without such right,
none of the Parties would have entered into this Agreement. Each Party agrees that it will not oppose the granting of specific performance
and other equitable relief on the basis that the other Parties have an adequate remedy at Law.

17.
Governing Law and Venue; Service of Process; Waiver of Jury Trial.


 


(a)
This Agreement, and all claims or causes of action based upon, arising out of or related to this Agreement or the transactions contemplated
hereby shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without giving effect to principles
or rules of conflict of laws to the extent such principles or rules would require or permit the application of Laws of another jurisdiction.


 


(b)
Any Proceeding based upon, arising out of or related to this Agreement, or the transactions contemplated hereby, shall be brought in
the Court of Chancery of the State of Delaware or, if such court lacks jurisdiction, the state or federal courts in the State of Delaware,
and each of the parties irrevocably submits to the exclusive jurisdiction of each such court in any such Proceeding, waives any objection
it may now or hereafter have to personal jurisdiction, venue or to convenience of forum, agrees that all claims in respect of the Proceeding
shall be heard and determined only in any such court, and agrees not to bring any Proceeding arising out of or relating to this Agreement
or the transactions contemplated hereby in any other court. Nothing herein contained shall be deemed to affect the right of any party
to serve process in any manner permitted by Law, or to commence legal proceedings or otherwise proceed against any other party in any
other jurisdiction, in each case, to enforce judgments obtained in any Proceeding brought pursuant to this Section 17.


 


(c)
EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW ANY AND ALL RIGHT TO
TRIAL BY JURY IN ANY ACTION BASED UPON, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.


 


18.
Counterparts; Electronic Signatures. This Agreement may be executed in one or more counterparts, each of which shall be deemed
to be an original, but all of which shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page
to this Agreement by e-mail, or scanned pages shall be effective as delivery of a manually executed counterpart to this Agreement.


 


19.
Headings. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning
or interpretation of this Agreement.


 


20.
Mutual Drafting. Each party hereto has participated in the drafting of this Agreement, which each party acknowledges is the result
of extensive negotiations between the parties. If an ambiguity or question of intent or interpretation arises, this Agreement shall be
construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by
virtue of the authorship of any provision.


 




    	9



    	 



    

 


21.
No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or remedy under
this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of
such party. No single or partial exercise of any right, power or remedy under this Agreement by a party hereto, and no abandonment or
discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof
or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver
of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Agreement
shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or
constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without
such notice or demand.


 


22.
Interpretation. The words “include,” “includes,” and “including” will
be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed
to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context
otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,”
“hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision
unless expressly so limited. The parties hereto intend that each representation, warranty and covenant contained herein will have independent
significance. If any party hereto has breached any representation, warranty or covenant contained herein in any respect, the fact that
there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity)
which such party has not breached will not detract from or mitigate the fact that such party is in breach of the first representation,
warranty or covenant. References to any person include the successors and permitted assigns of that person. 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.
All references in this to numbers of shares, per share amounts and purchase prices shall be appropriately adjusted to reflect any stock
split, cash dividend, reverse stock split, stock dividend, reorganization, recapitalization, reclassification, combination, exchange
of shares or other like change or transaction after the date hereof.


 


23.
Non-Recourse. Without limiting any rights of any party against any other party to the Merger Agreement or to any other Ancillary
Document, this Agreement may only be enforced against, and any claim or cause of action based upon, arising out of or related to this
Agreement may only be brought against, the entities that are expressly named as parties hereto, and then only with respect to the specific
obligations set forth herein with respect to such party. Without limiting any rights of any party against another party to the Merger
Agreement or to any other Ancillary Document, except to the extent named as a party to this Agreement (and then only to the extent of
the specific obligations undertaken by such named party in this Agreement), (a) no past, present or future director, officer, employee,
incorporator, member, partner, stockholder, Affiliate, agent, attorney, advisor or representative or Affiliate of any named party to
this Agreement and (b) no past, present or future director, officer, employee, incorporator, member, partner, stockholder, Affiliate,
agent, attorney, advisor or representative or Affiliate of any of the foregoing shall have any liability (whether in contract, tort,
equity or otherwise) for any one or more of the representations, warranties, covenants, agreements or other obligations or liabilities
of any one or more of the parties under this Agreement or for any claim based on, arising out of, or related to this Agreement.
