 5

Miscellaneous

the service of the summons and complaint and any other process in any action or proceeding relating to the transactions contemplated by this Agreement, for and on 

  
 6 

 
behalf of itself or any of its properties or assets, in accordance with Section 6.5 or in such other manner as may be permitted by applicable Law, and nothing in this

or proceeding to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or, only if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any federal court within the State of

agreements of each such party contained in this Agreement relate to special, unique and extraordinary matters and (b) a violation of any of the covenants, obligations or agreements of each such party hereto contained in this Agreement will
cause the parties hereto irreparable injury for which adequate remedies are not available at law. Therefore, each party hereto agrees that any other party shall be entitled to an injunction, restraining order or such other equitable relief (without
the requirement to post bond) as a court of competent jurisdiction may deem necessary or appropriate to restrain such other party, as the case may be, from committing any violation of such covenants, obligations or agreements and to specifically

(a) Acquisition Sub will commence a tender offer to purchase all of the outstanding shares of Company Common Stock (such offer as it may be amended from time to time as permitted by the Merger Agreement, the “Offer”), and
(b) following the consummation of the Offer, Acquisition Sub will be merged with and into the Company (the “Merger”), with the Company being the surviving corporation, all upon the terms and subject to the conditions set forth
in the Merger Agreement; and 
 WHEREAS, as a condition to their willingness to enter into and perform their obligations under the Merger
Agreement, Parent and Acquisition Sub have requested that each Company Stockholder enter into this Agreement, and each Company Stockholder has agreed to do so in order to induce Parent and Acquisition Sub to enter into, and in consideration of their
entering into, the Merger Agreement; 
 NOW, THEREFORE, in consideration of the foregoing and of the representations, warranties, covenants
and agreements herein contained, and intending to be legally bound hereby, the parties hereto agree as follows:

Agreement to Tender and Support 

Section 1.1. Agreement to Tender. 

(a) Each Company Stockholder agrees that as promptly as practicable after the commencement of the Offer, and in any event no later than the
tenth (10th) Business Day following the receipt by such Company Stockholder of all Offer Documents, including the letter of transmittal in the case of certificated Subject Shares, such
Company Stockholder shall tender into the Offer all of the Subject Shares owned by such Company Stockholder as of the date of such tender (with respect to each Company Stockholder, his her or its “Tender Date”), free and clear of
all of all claims, liens, encumbrances and security interests of any nature whatsoever that would prevent such Company Stockholder from tendering his, her or its shares in accordance with this Agreement or otherwise

 
complying with his, her or its obligations under this Agreement. If any Company Stockholder acquires any Subject Shares after such Company Stockholder’s Tender Date, such Company Stockholder
shall tender into the Offer such Subject Shares prior to the earlier of (x) three (3) Business Days following the date that such Company Stockholder shall acquire such Subject Shares and (y) the Expiration Date. Notwithstanding the
foregoing, the number of Subject Shares subject to this Agreement, together with the number of “Subject Shares” under all other Tender and Support Agreements entered into on the date hereof by Parent, Acquisition Sub and certain
stockholders of the Company, shall not under any circumstances equal or exceed 15% of the outstanding voting stock of the Company at the time that the Board of Directors of the Company approves the Merger Agreement. 

(b) Each Company Stockholder agrees that once the Subject Shares are tendered into the Offer, such Company Stockholder shall not withdraw the
tender of such Subject Shares unless and until this Agreement shall have been terminated in accordance with Article V. 
 Section 1.2.
Agreement to Vote. 
 (a) From the date hereof until the Termination Date, except to the extent waived in writing by Parent in its
sole and absolute discretion, at any meeting of the stockholders of the Company, however called, or at any adjournment thereof, or in connection with any written consent of the stockholders of the Company or in any other circumstances upon which a
vote, consent or other approval of all or some of the stockholders of the Company is sought, each Company Stockholder shall vote (or cause to be voted) all of such Company Stockholder’s Subject Shares to the extent such Subject Shares are
entitled to vote at such meeting or in such written consent: (a) in favor of adoption of the Merger Agreement; and (b) against the following actions (other than the Merger and the transactions contemplated by the Merger Agreement):
(i) any Acquisition Proposal or Alternative Acquisition Agreement; and (ii) any other action, transaction or proposal involving the Company or any of the Company Subsidiaries that is intended or would reasonably be expected to prevent,
nullify, impede, interfere with, frustrate, delay or postpone, in each case in any material respect the consummation of the Offer, the Merger, or the other transactions contemplated by the Merger Agreement. 

(b) In the event that a meeting of the stockholders of the Company is held, each Company Stockholder shall, or shall cause the holder of
record of its Subject Shares on any applicable record date to, appear at such meeting or otherwise cause its Subject Shares to be counted as present thereat for purposes of establishing a quorum. 

(c) Each Company Stockholder shall not enter into any agreement or understanding with any Person to vote or give instructions in any manner
inconsistent with the terms of this Section 1.2. 
 (d) Except as set forth in this Section 1.2, nothing in this Agreement
shall limit the right of any Company Stockholder to vote any Subject Shares in favor of, or against, or to abstain from voting with respect to, any matter presented to the Company’s stockholders, in its sole discretion.

ARTICLE IV 
 Covenants of
Each Company Stockholder 
 Each Company Stockholder severally covenants and agrees as follows: 

Section 4.1. Restriction on Transfer, Proxies, and Non-Interference. Except as contemplated by this Agreement or the Merger
Agreement, during the period beginning from the execution and delivery by the parties of this Agreement through the Termination Date, each Company Stockholder shall not (i) directly or indirectly, offer for sale, sell, transfer, tender, pledge,
encumber, assign, or otherwise dispose of (each, a “Transfer”), or agree to effect a Transfer of, any or all of such Company Stockholder’s Subject Shares, Subject Options, Subject Restricted Shares or any other securities of
the Company or any interest therein to any person, other than (x) Transfers to limited partners, members or other equityholders of Company Stockholder to the extent required in connection with any withdrawal or redemption of such limited
partner, member or equityholder pursuant to the terms of the partnership agreement, limited liability company operating agreement or other organizational documents of the Company Stockholder in effect as of the date hereof subject to the Company
Stockholder and its affiliates not directing, encouraging or soliciting any such limited partner, member or other equityholder to so withdraw or redeem and in the event any request for withdrawal or redemption is received, using reasonable best
effort to have such limited partner, member or other equityholder agree to waive any appraisal rights with respect to the Subject Shares it may acquire or (y) pursuant to the Merger Agreement or the Offer or in connection with the exercise of
any Subject Options or vesting of Subject Restricted Shares (it being understood and agreed that any shares of Company Common Stock issued upon the exercise of any Subject Options or Subject Restricted Shares that cease to be subject to any
forfeiture or vesting conditions, in each case shall be subject to the restrictions set forth in this Section 4.1); (ii) grant any proxies or powers of attorney, or any other authorization or consent with respect to any or all of such
Company Stockholder’s Subject Shares that could reasonably be expected to impede, interfere with or prevent the transactions contemplated by the Merger Agreement; (iii) deposit any of such Company Stockholder’s Subject Shares, Subject
Options or Subject Restricted Shares into a voting trust or enter into a voting agreement with respect to any of such Subject Shares, Subject Options or 

  
 4 

 
Subject Restricted Shares, other than pursuant to this Agreement or (iv) take any action that would make any representation or warranty of such Company Stockholder contained in this
Agreement to be untrue or incorrect in any material respect or that would reasonably be expected to have a material adverse effect on the ability of such Company Stockholder to perform such Company Stockholder’s obligations hereunder; in each
case other than (a) any Transfer by a Company Stockholder to one or more of its affiliates; provided, however, that prior to and as a condition to the effectiveness of any such Transfer, each proposed transferee agrees to be bound in writing by
this Agreement, or (b) as Parent and Acquisition Sub may otherwise agree in writing. 
 Section 4.2. Stop Transfer; Changes in
Voting Shares. Each Company Stockholder agrees with, and covenants to, Parent and Acquisition Sub that (i) this Agreement and the obligations hereunder shall attach to such Company Stockholder’s Subject Shares, Subject Options and
Subject Restricted Shares and shall be binding upon any person or entity to which legal or beneficial ownership shall pass, whether by operation of law or otherwise, including, without limitation, such Company Stockholder’s successors or
assigns and (ii) such Company Stockholder shall not request that the Company register the transfer (book-entry or otherwise) of any certificate or uncertificated interest representing any or all of the Company Stockholder’s Subject Shares,
Subject Options or Subject Restricted Shares, unless such Transfer is made in compliance with this Agreement. 
 Section 4.3.
Appraisal Rights. From and after the execution and delivery by the parties of this Agreement until the Termination Date, each Company Stockholder hereby agrees not to exercise, assert or perfect, or attempt to exercise, assert or perfect, any
rights of appraisal or rights to dissent from the Merger that such Company Stockholder may have with respect to the Subject Shares (including, without limitation, under Section 262 of the DGCL). 

Section 4.4. Additional Securities. In the event any Company Stockholder becomes the record or beneficial owner of (i) any

owner of its, his or her shares of Company Common Stock, Subject Options and/or Subject Restricted Shares. Nothing contained in this Agreement shall limit the rights and obligations of any Company Stockholder, any of its affiliates, Representatives
or any employee of any of its affiliates in his or her capacity as an employee, director or officer of the Company and the agreements set forth herein shall in no way restrict any director or officer of the Company in the exercise of his or her
fiduciary duties as a director or officer of the Company. 
 Section 4.6. Documentation and Information. Each Company
Stockholder (i) consents to and authorizes the publication and disclosure by Parent and its affiliates of his, her or its identity and holding of such Company Stockholder’s Subject Shares and the nature of his, her or its commitments and
obligations under this Agreement in any announcement or disclosure required by the SEC or other Governmental Authority, the Offer Documents, or any other disclosure document in connection with the Offer, the Merger or any of the other transactions
contemplated by the Merger Agreement or this Agreement, and (ii) agrees to give to Parent reasonably promptly any information it may reasonably require for the preparation of any such disclosure documents to the extent such information is
required by Applicable Law. Each Company Stockholder agrees to promptly notify Parent of any required corrections with respect to any written information supplied by it specifically for use in any such disclosure document, if and to the extent that
any shall have become false or misleading in any material respect. 

  
 5 

 Section 4.7. No Solicitation. 

(a) During the term of this Agreement, each Company Stockholder agrees that it shall not (whether directly or indirectly through its advisors,
agents or other intermediaries), engage in any conduct prohibited by Section 7.03 of the Merger Agreement, provided, however, that any such conduct by a Company Stockholder, or by an affiliate of such Company Stockholder, who is
an officer or director of the Company shall be deemed to have been engaged in by such Company Stockholder, or such affiliate of such Company Stockholder, in his or her capacity as an officer or director and any claim by Parent or any of its
affiliates in respect of such conduct shall first be brought against the Company rather than directly against such Company Stockholder or such affiliate of such Company Stockholder, and such Company Stockholder or such affiliate of such Company
Stockholder shall only be pursued directly if the Company is able to successfully argue that the conduct was taken in such Company Stockholder’s or such affiliate of such Company Stockholder’s capacity as a stockholder rather than as an
officer or director. 
 (b) Notwithstanding anything to the contrary in this Agreement, solely to the extent the Company is permitted to
take the actions set forth in Section 7.03(b) of the Merger Agreement with respect to an Acquisition Proposal, each Company Stockholder and its affiliates and Representatives will be free to participate in any discussions or negotiations
regarding such Acquisition Proposal with the Person making such Acquisition Proposal, provided that (i) such Company Stockholder has not breached this Section 4.7 and (ii) such action by such Company Stockholder and its affiliates and
Representatives would be permitted to be taken by the Company pursuant to Section 7.03(b) of the Merger Agreement.

(iii) the first Business Day following the End Date, provided, however, that the right to terminate this Agreement pursuant to this clause (iii) is not available to any Company Stockholder whose breach of this Agreement principally causes
the failure of the Offer to be consummated by such time, (v) the entry without the prior written consent of each of the Company Stockholders into any amendment or modification to the Merger Agreement or any waiver of any of the Company’s
rights under the Merger Agreement, in each case, that results in (1) a decrease in the Offer Price or Merger Consideration (each as defined in the Merger Agreement on the date hereof), except to the extent such decrease is in accordance with
the provisions of Section 2.01(e) of the Merger Agreement or (2) a change in the form of consideration to be paid in the Offer or in the form of Merger Consideration (vi) the termination or withdrawal of the Offer by Parent or
Acquisition Subsidiary, and (vii) the expiration of the Offer without Acquisition Subsidiary having accepted for payment the Shares validly tendered in the Offer. In the event of termination of this Agreement pursuant to this Section 5.1,
(i) all obligations of the parties under this Agreement will terminate, without any liability on the part of any party; provided, however, no such termination shall relieve any party from liability for any breach hereof prior to such
termination, and (ii) each Company Stockholder shall be permitted to withdraw, and unless otherwise agreed to by such Company Stockholder, shall be deemed to have validly and timely withdrawn, and Subject Securities tendered in the Offer.

 ARTICLE VI 

Miscellaneous 

Section 6.1. Governing Law; Jurisdiction; Waiver of Jury Trial.

the service of the summons and complaint and any other process in any action or proceeding relating to the transactions contemplated by this Agreement, for and on behalf of itself or any of its properties or assets, in accordance with
Section 6.5 or in such other manner as may be permitted by applicable Law, and nothing in this Section 6.1(b) shall affect the right of any party to serve legal process in any other manner permitted by applicable Law;
(ii) irrevocably and unconditionally consents and submits itself and its properties and assets in any action or proceeding to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or, only if the Court of Chancery of the

recognition and enforcement of any judgment in respect thereof; (iii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court; (iv) agrees that any actions or

IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF PARENT, ACQUISITION SUB OR THE COMPANY STOCKHOLDERS
IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF.

acknowledges and agrees that (a) the covenants, obligations and agreements of each such party contained in this Agreement relate to special, unique and extraordinary matters and (b) a violation of any of the covenants, obligations or
agreements of each such party hereto contained in this Agreement will cause the parties hereto irreparable injury for which adequate remedies are not available at law. Therefore, each party hereto agrees that any other party shall be entitled to an
injunction, restraining order or such other equitable relief (without the requirement to post bond) as a court of competent jurisdiction may deem necessary or appropriate to restrain such other party, as the case may be, from committing any
violation of such covenants, obligations or agreements and to specifically enforce the terms of this Agreement. These injunctive remedies are cumulative and in addition to any other rights and remedies any party hereto may have under applicable Law.

 Section 6.3. Assignment; No Third Party Beneficiaries. This Agreement shall not be assignable or otherwise transferable by a
party without the prior consent of the other parties, and any attempt to so assign or otherwise transfer this Agreement without such consent shall be void and of no effect; provided, however, that Parent may,

  
 7 

 
in its sole discretion, assign or transfer all or any of its rights, interests and obligations under this Agreement to any direct or indirect wholly owned subsidiary of Parent, but no such
assignment shall relieve Parent from its obligations under this Agreement. This Agreement shall be binding upon the respective heirs, successors, legal representatives and permitted assigns of the parties hereto. Nothing in this Agreement shall be

than voided, if possible, in order to achieve the intent of the parties hereto to the maximum extent possible. In any event, the invalidity or unenforceability of any provision of this Agreement
in any jurisdiction shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of this Agreement, including that provision, in any other jurisdiction. Upon such

subject or submits. 
 Section 6.13. Counterparts. This Agreement may be executed in two or more counterparts, each of which
when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier or pdf shall be effective as
delivery of a manually executed counterpart of this Agreement.
