Proxy. 
 (a) From and after the date hereof until the Expiration Date, each Stockholder hereby irrevocably and unconditionally
grants to, and appoints, Parent and each of its executive officers or other designees as such Stockholder’s proxy and attorney-in-fact (with full power of
substitution), for and in the name, place and stead of such Stockholder, to vote or cause to be voted (including by proxy or written consent, if applicable) its Securities in accordance with the Required Votes. 

(b) Each Stockholder hereby revokes any proxies heretofore given in respect of the Securities, if any, are revocable. 

(c) Each Stockholder hereby affirms that the irrevocable proxy set forth in this Section 1.2 is given in connection
with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Stockholder under this Agreement; provided, that each Stockholder’s grant of the proxy contemplated by
this Section 1.2 shall only entitle Parent or its designee to vote such Stockholder’s Securities in accordance with the Required Votes, and each Stockholder shall retain the authority to vote its Securities on all
other matters. Each Stockholder hereby further affirms that the irrevocable proxy set forth in this Section 1.2 is coupled with an interest and, except upon the occurrence of the Expiration Date, is intended to be
irrevocable. 
 Section 1.3 Restrictions. 

(a) Each Stockholder hereby agrees that, from the date hereof until the Expiration Date, it shall not, directly or indirectly, (i) except
in connection with the consummation of the Merger, sell, transfer (by gift or otherwise), assign, tender in any tender or exchange offer, pledge, encumber, hypothecate or similarly dispose of (by merger, by testamentary disposition, by operation of
law or otherwise), either voluntarily or involuntarily (a “Transfer”), or to enter into any contract, option or other arrangement or understanding with respect to the Transfer, any Securities or any Company Warrants;
(ii) except in connection with the consummation of the Merger, deposit any Securities into a voting trust or enter into a voting agreement or arrangement or grant any proxy, consent or power of attorney with respect thereto that is inconsistent

this Section 1.3(a) shall be null and void; provided, further, that if the Merger Agreement is terminated, then, from and after the date on which the Merger Agreement is terminated until the Expiration Date, each Stockholder may

meaning of Rule 144 promulgated under the Securities Act and (y) to the actual knowledge of such Stockholder at the time of Transfer, such Transfer would not cause any Person to acquire beneficial ownership (as such term is used in Rule 13d-3 of the Exchange Act) of Securities or Warrants representing more than 10% of the aggregate number of shares of Company Common Stock then held by all of the Stockholders. 

  
 3

of Parent Common Stock. Any transfer in violation of this Section 1.3(b) shall be null and void. 

Section 1.4 Company Change in Recommendation. Notwithstanding anything to the contrary in this
Agreement, if at any time following the date hereof and until the termination of the Merger Agreement pursuant to and in compliance with the terms thereof there occurs a Company Change in Recommendation pursuant to Section 5.8(c) of the Merger
Agreement (a “Change of Recommendation Event”), then the obligations of each Stockholder to vote its Securities in accordance with Section 1.1(a) and Section 1.1(e), shall
be limited to the number of shares of Company Common Stock held by such Stockholder, rounded down to the nearest whole share, equal to the product of (a) such Stockholder’s Pro Rata Share multiplied by (b) the Covered Company Common
Stock (such amount for each Stockholder, the “Covered Securities”); provided that all other obligations and restrictions contained in this Agreement, including those set forth in
Section 1.1(b), Section 1.1(c) and Section 1.1(d) shall continue to apply to all of such Stockholder’s Securities; provided, further, however, that if a Change of Recommendation Event occurs,
notwithstanding any other obligations hereunder, any Stockholder shall be expressly permitted to vote its Securities that are not Covered Securities in its sole discretion with respect to any Merger Proposal, including against such Merger Proposal.
For purposes of this Agreement, (i) the “Covered Company Common Stock” shall mean the total number of shares of Company Common Stock outstanding as of the record date of the applicable stockholder meeting multiplied by
0.3999 and (ii) such Stockholder’s “Pro Rata Share” shall mean the quotient of the number of Securities held by such Stockholder divided by the number of Securities held by all of the Voting Agreement Stockholders
in the aggregate. 
 Section 1.5 Injunction. Notwithstanding anything to the contrary in this
Agreement, if at any time following the date hereof and prior to the Expiration Date a Governmental Body of competent jurisdiction enters an order restraining, enjoining or otherwise prohibiting the Stockholders or their Affiliates from
(a) consummating the transactions contemplated by the Merger Agreement or (b) taking any action pursuant to Section 1.1 or Section 1.2 of this Agreement, then (i) the obligations of
each Stockholder set forth in Section 1.1 and the irrevocable proxy and power of attorney in Section 1.2 shall be of no force and effect for so long as such order is in effect and, in the case of
clause (b), solely to the extent such order restrains, enjoins or otherwise prohibits such Stockholder from taking any such action, and (ii) each Stockholder shall cause the Securities to not be represented in person or by proxy at any
meeting at which a vote of such Stockholder on the Merger is requested. Notwithstanding anything to the contrary in this Section 1.5, the restrictions set forth in Section 1.3(a) shall continue to

 5

Section 5.3 Amendments; Waivers. This Agreement may not be amended, except by an instrument in writing
signed by or on behalf of each of the Parties. The rights and remedies of the Parties are cumulative and not alternative. Neither any failure nor any delay by any Party in exercising any right, power, or privilege under this Agreement or any of the
documents referred to in this Agreement will operate as a waiver of such right, power, or privilege and no single or partial exercise of any such right, power, or privilege will preclude any other or further exercise of such right, power, or
privilege or the exercise of any other right, power, or privilege. To the maximum extent permitted by applicable Legal Requirements, (i) no waiver that may be given by a Party will be applicable except in the specific instance for which it is
given; and (ii) no notice to or demand on one Party will be deemed to be a waiver of any obligation of that Party or of the right of the Party giving such notice or demand to take further action without notice or demand as provided in this
Agreement or the documents referred to in this Agreement. 
 Section 5.4 Assignment. No Party may
assign any of its rights or delegate any of its obligations under this Agreement without the prior written Consent of the other Parties. Any attempted assignment of this Agreement or of any such rights or delegation of obligations without such
consent shall be void and of no effect. This Agreement will be binding upon, and shall be enforceable by and inure solely to the benefit of, the parties hereto and their respective successors and permitted assigns. 

Section 5.5 No Partnership, Agency, or Joint Venture. This Agreement is intended to create, and
creates, a contractual relationship and is not intended to create, and does not create, any agency, partnership, joint venture or any like relationship among the Parties. 

Section 5.6 Entire Agreement. This Agreement, including the schedules, exhibits, and amendments hereto
and any other document or instrument referred to herein constitute the entire agreement among the Parties and supersede all other prior or contemporaneous agreements and understandings, both written and oral, among or between any of the Parties with
respect to the subject matter hereof and thereof.

 Section 5.7 No Third-Party Rights. Nothing in this
Agreement, express or implied, is intended to or shall confer upon any Person (other than the Parties) any right, benefit, or remedy of any nature whatsoever under or by reason of this Agreement. 

Section 5.8 Jurisdiction; Specific Performance; Waiver of Jury Trial. 

(a) The Parties submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware or, if such Court does not have subject
matter jurisdiction, to the Superior Court of the State of Delaware or, if jurisdiction is vested exclusively in the Federal courts of the United States, the Federal courts of the United States sitting in the State of Delaware, and hereby
irrevocably and unconditionally agree that all claims with respect to any such claim shall be heard and determined in such Delaware court or, to the extent required by applicable Legal Requirements, in such Federal courts of the United States
sitting in the State of Delaware. The Parties agree that a final judgment in any such claim is conclusive and may be enforced in any other jurisdiction by suit on the judgment or in any other manner provided by Legal Requirements. Each Party
irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this
Agreement or any related matter in any Delaware state or Federal court located in the State of Delaware and the defense of an inconvenient forum to the maintenance of such claim in any such court. 

(b) The Parties acknowledge and agree that each Party would be irreparably damaged if any of the provisions of this Agreement are not performed
in accordance with their specific terms and that any breach of this Agreement by any Party could not be adequately compensated by monetary damages alone. Accordingly, in addition to any other right or remedy to which any Party may be entitled, at
law or in equity, each Party shall be entitled to enforce any provision of this Agreement by a decree of specific performance and temporary, preliminary, and permanent injunctive relief to prevent breaches or threatened breaches of any of the
provisions of this Agreement, without posting any bond or other undertaking. In the event that any action shall be brought by a Party in equity to enforce the provisions of the Agreement, no other Party shall allege or assert, and each Party hereby
waives the defense, that there is an adequate remedy at law or that the award of specific performance is not an appropriate remedy for any reason of law or equity. 

(c) Each of the parties irrevocably waives any and all rights to trial by jury in any action or proceeding between the Parties arising out of
or relating to this Agreement and the transactions contemplated hereby. 
 Section 5.9 Governing
Law. This Agreement and the agreements, instruments, and documents contemplated hereby, shall be governed by, and construed in accordance with, the Legal Requirements of the State of Delaware, without regard to any applicable principles of

subject of representations and warranties set forth herein, copies of all addenda, exhibits, schedules, or amendments have been provided on or prior to the date of this Agreement to the Party to whom such representations and warranties are being
made). This Agreement was negotiated by the Parties with the benefit of legal representation and any rule of construction or interpretation otherwise requiring this Agreement to be construed or interpreted against any Party shall not apply to any
construction or interpretation hereof. The headings contained in this Agreement are for convenience of reference only, shall not be deemed to be a part of this Agreement, and shall not be referred to in connection with the construction or
interpretation of this Agreement.

Parties; it being understood that all Parties need not sign the same counterpart. 
 (b) The exchange of signed copies of this Agreement or
