WHEREAS, as a condition

AGREEMENT:


 


NOW, THEREFORE, in
consideration of the foregoing and the mutual covenants and agreements set forth herein and in the Merger Agreement, and intending
to be legally bound hereby, the parties hereto agree as follows:


 


SECTION 1.     Grant of Irrevocable Proxy;
Appointment of Proxy.


 


(a)          The
Stockholder hereby agrees that, during the Term, the Stockholder will, at every meeting of the stockholders of the Company called
for such purpose, and at every adjournment or postponement thereof (or in any other circumstances upon which a vote, consent or
approval is sought, including by written consent), not vote any of his, her or its Shares at such meeting in favor of, or consent
to, and will vote against and not consent to, the approval of any (i) Acquisition Proposal, (ii) reorganization, recapitalization,
dissolution, liquidation or winding-up of the Company or any other extraordinary transaction involving the Company other than the
Offer, the Merger or any of the other transactions contemplated by the Merger Agreement, or (iii) corporate action, the consummation
of which would prevent or materially delay the consummation of any of the transactions contemplated by the Merger Agreement. The
Stockholder shall use his, her or its commercially reasonable efforts to ensure that, during the Term, any other Person having
voting power with respect to any of his, her or its Shares will not vote any such Shares in favor of or consent to, and will vote
against, the approval of the matters described in clauses (i) through (iii) of the preceding sentence.


 




     


     

    

 


(b)          The
Stockholder hereby revokes (or agrees to cause to be revoked) any and all previous proxies granted with respect to the Shares as
they relate to the matters set forth in Section 1(a). By entering into this Agreement, the Stockholder hereby grants a proxy
appointing Parent as the Stockholder’s attorney-in-fact and proxy, with full power of substitution, for and in the Stockholder’s
name, to vote, express consent or dissent, or otherwise to utilize such voting power in the manner contemplated by Section 1(a)
as Parent or its proxy or substitute shall, in Parent’s sole discretion, deem proper with respect to the Shares.


 


(c)          The
Stockholder hereby affirms that the proxy granted by the Stockholder pursuant to this Section 1 is irrevocable and is granted
in consideration of Parent and Acquisition Sub entering into this Agreement and the Merger Agreement and incurring certain related
fees and expenses. The Stockholder hereby further affirms that the irrevocable proxy is coupled with an interest and, except as
set forth in this Section 1 or in Section 6, is intended to be irrevocable in accordance with the provisions of Section
212 of the DGCL. If, during the Term, for any reason the proxy granted herein is not irrevocable, then the Stockholder agrees that
it shall vote his, her or its Shares in accordance with Section 1(a) as instructed by Parent in writing. The parties agree
that the foregoing shall be a voting agreement created under Section 218 of the DGCL.


 


(d)          Parent
hereby acknowledges and agrees that the proxy set forth in this Section 1 shall not be exercised to vote, consent or act
on any matter except as specifically contemplated by Section 1(a), and Parent agrees not to exercise the proxy granted herein
for any purpose other than the purposes described in Section 1(a). The proxy set forth in this Section 1 shall be
revoked, terminated and of no further force or effect automatically without further action of any party upon the termination of
this Agreement. The power of attorney granted herein is a durable power of attorney and shall survive the dissolution, bankruptcy,
death or incapacity of the Stockholder.


 


SECTION 2.      Representations
and Warranties of the Stockholder. The Stockholder hereby represents and warrants to Parent and Acquisition Sub as follows:


 


(a)          The
Stockholder (i) is the record and beneficial owner of the Shares set forth on the signature page hereto, and (ii) except as set
forth on Schedule I hereto, neither holds nor has any beneficial ownership interest in any other shares of Company Common
Stock or any performance-based stock units, restricted stock, deferred stock units, options (including any granted pursuant to
a Stock Plan) or warrants to acquire shares of Company Common Stock or other right or security convertible into or exercisable
or exchangeable for shares of Company Common Stock.


 


(b)          The
execution, delivery and performance by the Stockholder of this Agreement and the consummation by the Stockholder of the transactions
contemplated hereby are within the powers of the Stockholder and, if applicable, have been duly authorized by all necessary corporate,
company, partnership, trust or other action. If this Agreement is being executed in representative or fiduciary capacity, the Person
signing this Agreement has full power and authority to enter into and perform this Agreement.

(c)          This
Agreement has been duly authorized, executed and delivered by the Stockholder and, assuming this Agreement constitutes a valid

availability of the remedy of specific performance or injunctive or other forms of equitable relief may be subject to equitable
defenses and would be subject to the discretion of the court before which any proceeding therefor may be brought.

the execution and delivery of this Agreement by the Stockholder nor the consummation by the Stockholder of the transactions contemplated
hereby will result in a violation of, or a default under, or conflict with, any contract, trust, commitment, agreement, understanding,
arrangement or restriction of any kind to which the Stockholder is a party or by which the Stockholder or any of his, her or its
Shares are bound, except as could not reasonably be expected, either individually or in the aggregate, to impair, impede, delay

contemplated hereby. The consummation by the Stockholder of the transactions contemplated hereby will not (i) violate any provision
of any law, judgment, order or decree applicable to the Stockholder, or (ii) require any consent, approval, or notice under any

nominee or custodian for the benefit of the Stockholder, or by the depository under the Offer, free and clear of all liens, claims,
security interests, proxies, voting trusts or agreements, options, rights (other than community property interests), understandings

in respect of such Shares (collectively, “Encumbrances”), except for (i) any such Encumbrances arising hereunder,
and (ii) Encumbrances imposed by federal or state securities laws (collectively, “Permitted Encumbrances”).


 


(f)          As
of the date of this Agreement, there are no Actions pending or, to the knowledge of the Stockholder, threatened against the Stockholder
at law or in equity before or by any Governmental Entity that could reasonably be expected to impair the ability of the Stockholder
to perform the Stockholder’s obligations hereunder or to consummate the transactions contemplated hereby.

the execution and delivery of this Agreement by Parent or Acquisition Sub nor the consummation by Parent or Acquisition Sub of
the transactions contemplated hereby will result in a violation of, or a default under, or conflict with, any contract, trust,
commitment, agreement, understanding, arrangement or restriction of any kind to which Parent or Acquisition Sub is a party or by
which Parent or Acquisition Sub or any of its assets are bound, except as could not reasonably be expected, either individually

with the performance of the Stockholder’s obligations hereunder, or seek to do or solicit any of the foregoing actions, or
cause or permit any other Person to take any of the foregoing actions. Without limiting the generality of the foregoing, during

of this Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby, and
hereby waive, and agree not to assert, as a defense in any Action for the interpretation or enforcement hereof or of any such document,

(iii)        The
parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed
by any party in accordance with their specific terms or were otherwise breached by such party. It is accordingly agreed that, prior
to the termination of this Agreement pursuant to Section 6, the non-breaching parties shall be entitled to an injunction
or injunctions to prevent breaches of this Agreement by the other party and to enforce specifically the terms and provisions of
this Agreement against the other party, this being in addition to any other remedy to which such party is entitled at law or in
equity, and each party hereby waives any requirement for the posting of any bond or similar collateral in connection therewith.
Prior to the termination of this Agreement pursuant to Section 6, each party hereby agrees that it will not oppose the granting

at law or (ii) an award of specific performance is not an appropriate remedy for any reason at law or in equity.

Successors and Assigns. No party may assign either this Agreement or any of its rights, interests, or obligations hereunder,
other than collateral assignments for the benefit of lenders under existing security agreements existing as of the date hereof,
without the prior written approval of the other parties. Subject to the preceding sentence, this Agreement shall be binding upon
and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. Any purported assignment
not permitted under this Section 10(f) shall be null and void.


 


(g)          Severability.
Any term or provision of this Agreement that is held by a court of competent jurisdiction or other Governmental Entity to be invalid,
void or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms
and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or
in any other jurisdiction. If the final judgment of a court of competent jurisdiction or other Governmental Entity declares that
any term or provision of this Agreement is invalid, void or unenforceable, 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 to the end that
the transactions contemplated hereby are fulfilled to the fullest extent possible.


 


(h)          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.


 


(i)          Counterparts.
This Agreement may be executed in counterparts (each of which shall be deemed to be an original but all of which taken together
shall constitute one and the same agreement) and shall become effective when one or more counterparts have been signed by each
of the parties and delivered (by electronic communication, facsimile or otherwise) to the other parties.


 


(j)          Amendment.
This Agreement may be amended at any time by the parties hereto by written agreement executed and delivered by each of the parties
hereto. 


 


(k)          Action

or understanding herein as a director or officer of the Company. The Stockholder signs this Agreement solely in his, her or its
capacity as an owner of the Shares, and nothing herein shall limit or affect any actions taken in the Stockholder’s capacity
as an officer or director of the Company, including complying with or exercising the Stockholder’s fiduciary duties as a
