 COVENANTS OF THE STOCKHOLDER 

The Stockholder hereby covenants and agrees as follows: 
 Section 4.1 No Transfer. 
 (a) Other than pursuant to the terms of
this Agreement or the Merger Agreement, without the prior written consent of Parent or as otherwise provided in this Agreement, during the term of this Agreement, the Stockholder hereby agrees to not, directly or indirectly, (i) grant any
proxies, options, rights of first offer or refusal or power of attorney or enter into any voting trust or other agreement or arrangement with respect to, or restricting the voting of, any Covered Shares, (ii) enter into a swap or any other
agreement or any transaction that transfers, in whole or in part, the economic consequence of ownership of any Covered Shares or (iii) sell, pledge, assign, transfer, tender, exchange, offer, encumber or otherwise dispose of (including by
merger or consolidation), or enter into any contract, option or other arrangement or understanding with respect to the direct or indirect assignment, transfer, tender, exchange, offer, encumbrance or other disposition of (including by merger or
consolidation) (each, a “Transfer”), any Covered Shares. Any action taken or attempted to be taken in violation of the preceding sentence will be null and void. The Stockholder further agrees to authorize and request Parent and the
Company to notify the Company’s transfer agent that there is a stop transfer order consistent herewith with respect to the Covered Shares and that this Agreement places limits on the voting of the Covered Shares. Notwithstanding the foregoing
or anything to the contrary set forth in this Agreement, the Stockholder may Transfer any or all of the Covered Shares (i) by will, or by operation of law, in which case this Agreement shall, to the extent permitted by Law, bind the transferee,
or (ii) to affiliates, trusts and charitable organizations, so long as the transferee, prior to such Transfer executes a counterpart of this Agreement (with such modifications as Parent may reasonably request solely to reflect such Transfer)
and agrees to be bound by its terms. 
 (b) The Stockholder hereby covenants and agrees that for a period of 90 days following
the Effective Time (the “Lock-Up Period”), such Stockholder shall not Transfer or consent to any Transfer of, any shares of Parent Common Stock received by such Stockholder in the Merger with respect to the Covered Shares, or any
interest therein, or enter into any contract, option or other arrangement or understanding with respect to the direct or indirect Transfer of, any shares of Parent Common Stock received by such Stockholder in the Merger with respect to the Covered
Shares or any interest therein to any Person (other than Parent); provided, however,

  

 -6- 

 
that the Stockholder may participate during the Lock-Up Period with respect to its shares of Parent Common Stock in any merger, tender offer or other business combination or other transaction, in
each case, which the Board of Directors of Parent has recommended to Parent’s stockholders; provided, further, that after the Effective Time and during the Lock-Up Period, the Stockholder may Transfer any or all of the shares of
Parent Common Stock received by such Stockholder in the Merger with respect to the Covered Shares (i) by will, or by operation of law, in which case this Section 4.1(b) shall, to the extent permitted by Law, bind the transferee
until the expiration of the Lock-Up Period, or (ii) to affiliates, trusts and charitable organizations, so long as the transferee, prior to such Transfer executes a counterpart of this Agreement (with such modifications as Parent may reasonably
request solely to reflect such Transfer) and agrees to be bound by its terms (including this Section 4.1(b)). The Stockholder hereby agrees that, in order to ensure compliance with the restrictions referred to herein, Parent may issue
appropriate stop transfer instructions to its transfer agent in respect of the Stockholder’s Parent Common Stock. Parent agrees that it will cause any stop transfer instructions imposed pursuant to this Section 4.1(b) to be lifted,
and any legended certificates of Parent Common Stock delivered to the Stockholder pursuant to the Merger Agreement to be replaced with certificates not bearing such legend, promptly following the termination of the Lock-Up Period. The restrictions
on transfer provided in this Section 4.1(b) shall be in addition to any restrictions on transfer of the Parent Common Stock imposed by any applicable Laws. 
 Section 4.2 Public Announcement. The Stockholder shall consult with Parent before issuing any press releases or otherwise making any public statements with respect to the transactions
contemplated herein, in such Stockholder’s capacity as a stockholder of the Company, except as may be required by applicable Law. The Stockholder hereby consents to disclosure in the Registration Statement and the Proxy Statement (including all
documents and schedules filed with the SEC) and press releases with respect to the Merger in accordance with the Merger Agreement, of the identity of the Stockholder and ownership of the Covered Shares and the nature of such Stockholder’s
commitments, arrangements and understandings pursuant to this Agreement. 
 Section 4.3 Additional Shares. The
Stockholder shall promptly notify Parent of the number of any new Covered Shares acquired by the Stockholder, if any, after the date hereof. Any such shares shall be automatically subject to the terms of this Agreement as though owned by the
Stockholder on the date hereof. 
 Section 4.4 No Restraint on Officer or Director Action; Etc. Notwithstanding
anything to the contrary herein, Parent hereby acknowledges and agrees that no provision in this Agreement shall limit or otherwise restrict the Stockholder with respect to any act or omission that the Stockholder may undertake or authorize in such
Stockholder’s capacity as a director or officer of the Company or any subsidiary thereof, including any vote that such individual may make as a director of the Company with respect to any matter presented to the Company’s board of
directors. The Stockholder has executed this Agreement solely in such Stockholder’s capacity as the record and/or beneficial owner of the Covered Shares and no action taken by the Stockholder in such Stockholder’s capacity as a director or
officer of the Company or any subsidiary thereof shall be deemed to constitute a breach of any provision of this Agreement.

indirectly, solicit, initiate, knowingly encourage or facilitate, or furnish or disclose non-public information relating to the Company in furtherance of, any inquiries or the making of any Alternative Proposal, or negotiate, explore or otherwise
engage in discussions with any Person with respect to any Alternative Transaction, or approve, endorse or recommend any Alternative Transaction, or enter into any agreement, arrangement or understanding with respect to any Alternative Transaction
and (b) not to take any action which makes, or would reasonably be expected to make, any representation or warranty of such Stockholder herein untrue or incorrect in a material respect. The Stockholder shall notify Parent promptly of any such
inquiries, proposals or offers received by, or any such discussions or negotiations sought to be initiated or continued with, the Stockholder or, to the Stockholder’s knowledge, any of its representatives, indicating the name of such Person and
providing to Parent a summary of the material terms of such proposal or offer for an Alternative Transaction. Notwithstanding the foregoing, the Stockholder shall be permitted to engage in discussions or negotiations with, or furnish or disclose
non-public information relating to the Company to, any Person or group of related Persons that has made an Alternative Proposal if, and only to the extent that, the Company is permitted under Section 4.3(b) of the Merger Agreement to engage in
discussions or negotiations with, or to furnish or disclose non-public information to, such Person or group of related Persons.

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

 ARTICLE I. 
 VOTING AGREEMENT

meeting is held, appear at such meeting or otherwise cause the Covered Shares as to which the Stockholder controls the right to vote to be counted as present thereat for the purpose of establishing a quorum, and (ii) vote (or cause to be voted)

Company and any of its subsidiaries (other than pursuant to the Merger) or any other Alternative Transaction, (D) against any amendment of the Company’s certificate of incorporation or by-laws other than as permitted by the Merger
Agreement, (E) in a manner that is not inconsistent with the publicly stated position or recommendation of Parent (but only to the extent Parent publicly states a position or recommendation) with respect to any other proposal, action or
transaction involving the Company or any of its Subsidiaries, which amendment or other proposal, action or transaction would reasonably be expected to in any manner impede, frustrate, prevent or nullify the Merger Agreement, the Company Stockholder

recapitalization by the Company or change in the capital structure of the Company (other than pursuant to or as permitted by the Merger Agreement). For the purposes of this Agreement, “Voting Period” shall mean the period commencing
on the date hereof and ending immediately prior to any termination of this Agreement in accordance with its terms pursuant to Section 5.1 hereof. The Stockholder further agrees not to commit or agree to take any action inconsistent with the
foregoing. 
 Section 1.2 Grant of Proxy. In order to secure the performance of Stockholder’s obligations under
this Agreement, the Stockholder hereby revokes any and all previous proxies granted with respect to the Covered Shares and irrevocably grants to, and appoints, Parent and each executive officer of Parent, and any other individual designated in
writing by Parent, as such Stockholder’s proxy and attorney-in-fact (with full power of substitution), for and in its name, place and stead, to be counted as present, vote, express consent or dissent or otherwise to act on behalf of such
Stockholder with respect to the Covered Shares in the manner contemplated by Section 1.1 during the Voting Period. The Stockholder understands and acknowledges that Parent is entering into the Merger Agreement in reliance upon the
Stockholder’s execution and delivery of this Agreement. The 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 the Stockholder under this Agreement. Except as provided for in the last sentence of

  

 -2- 

 
this Section 1.2, the Stockholder hereby (i) affirms that the irrevocable proxy is coupled with an interest and may under no circumstances be revoked and (ii) ratifies and confirms
all that the proxies appointed hereunder may lawfully do or cause to be done by virtue hereof. Notwithstanding any other provisions of this Agreement, the irrevocable proxy granted hereunder shall automatically terminate upon the termination of this
Agreement without any notice or other action by any person.

Stockholder hereby irrevocably and unconditionally waives, and agrees not to assert or perfect, any rights of appraisal, dissenters’ rights or similar rights that such Stockholder may have in connection with the Merger.

 ARTICLE IV. 
 COVENANTS OF THE STOCKHOLDER 
 The Stockholder hereby covenants and agrees
as follows: 
 Section 4.1 No Transfer. 
 (a) Other than pursuant to the terms of this Agreement or the Merger Agreement, without the prior written consent of Parent or as otherwise
provided in this Agreement, during the term of this Agreement, the Stockholder hereby agrees to not, directly or indirectly, (i) grant any proxies, options, rights of first offer or refusal or power of attorney or enter into any voting trust or
other agreement or arrangement with respect to, or restricting the voting of, any Covered Shares, (ii) enter into a swap or any other agreement or any transaction that transfers, in whole or in part, the economic consequence of ownership of any
Covered Shares or (iii) sell, pledge, assign, transfer, tender, exchange, offer, encumber or otherwise dispose of (including by merger or consolidation), or enter into any contract, option or other arrangement or understanding with respect to
the direct or indirect assignment, transfer, tender, exchange, offer, encumbrance or other disposition of (including by merger or consolidation) (each, a “Transfer”), any Covered Shares. Any action taken or attempted to be taken in
violation of the preceding sentence will be null and void. The Stockholder further agrees to authorize and request Parent and the Company to notify the Company’s transfer agent that there is a stop transfer order consistent herewith with
respect to the Covered Shares and that this Agreement places limits on the voting of the Covered Shares. Notwithstanding the foregoing or anything to the contrary set forth in this Agreement, the Stockholder may Transfer any or all of the Covered
Shares (i) by will, or by operation of law, in which case this Agreement shall, to the extent permitted by Law, bind the transferee, or (ii) to affiliates, trusts and charitable organizations, so long as the transferee, prior to such
Transfer executes a counterpart of this Agreement (with such modifications as Parent may reasonably request solely to reflect such Transfer) and agrees to be bound by its terms. 
 (b) The Stockholder hereby covenants and agrees that for a period of 90 days following the Effective Time (the “Lock-Up
Period”), such Stockholder shall not Transfer or consent to any Transfer of, any shares of Parent Common Stock received by such Stockholder in the Merger with respect to the Covered Shares, or any interest therein, or enter into any
contract, option or other arrangement or understanding with respect to the direct or indirect Transfer of, any shares of Parent Common Stock received by such Stockholder in the Merger with respect to the Covered Shares or any interest therein to any
Person (other than Parent); provided, however, that the Stockholder may participate during the Lock-Up Period with respect to its shares of Parent Common Stock in any merger, tender offer or other business combination or other
transaction, in each case, which the Board of Directors of Parent has recommended to Parent’s stockholders; provided, further, that after the Effective Time and during the Lock-Up Period, the Stockholder may Transfer any or all of
the shares of Parent Common Stock received by such Stockholder in the Merger with respect to the Covered Shares (i) by will, or by operation of law, in which case this Section 4.1(b) shall, to the extent permitted by Law, bind the
transferee until the expiration of the Lock-Up Period, or (ii) to affiliates, trusts and charitable organizations, so long as the transferee, prior to such Transfer executes a counterpart of this Agreement (with such modifications as Parent may
reasonably request solely to reflect such Transfer) and agrees to be bound by its terms (including this Section 4.1(b)). The Stockholder hereby agrees that, in order to ensure compliance with the restrictions referred to herein, Parent
may issue appropriate stop transfer instructions to its transfer agent in respect of the Stockholder’s Parent Common Stock. Parent agrees that it will cause any stop transfer instructions imposed pursuant to this Section 4.1(b) to
be lifted, and any legended certificates of Parent Common Stock delivered to the Stockholder pursuant to the Merger Agreement to be replaced with certificates not bearing such legend, promptly following the termination of the Lock-Up Period. The
restrictions on transfer provided in this Section 4.1(b) shall be in addition to any restrictions on transfer of the Parent Common Stock imposed by any applicable Laws. 
  

 -6- 

 Section 4.2 Public Announcement. The Stockholder shall consult with Parent
before issuing any press releases or otherwise making any public statements with respect to the transactions contemplated herein, in such Stockholder’s capacity as a stockholder of the Company, except as may be required by applicable Law. The
Stockholder hereby consents to disclosure in the Registration Statement and the Proxy Statement (including all documents and schedules filed with the SEC) and press releases with respect to the Merger in accordance with the Merger Agreement, of the
identity of the Stockholder and ownership of the Covered Shares and the nature of such Stockholder’s commitments, arrangements and understandings pursuant to this Agreement. 
 Section 4.3 Additional Shares. The Stockholder shall promptly notify Parent of the number of any new Covered Shares
acquired by the Stockholder, if any, after the date hereof. Any such shares shall be automatically subject to the terms of this Agreement as though owned by the Stockholder on the date hereof. 
 Section 4.4 No Restraint on Officer or Director Action; Etc. Notwithstanding anything to the contrary herein, Parent hereby
acknowledges and agrees that no provision in this Agreement shall limit or otherwise restrict the Stockholder with respect to any act or omission that the Stockholder may undertake or authorize in such Stockholder’s capacity as a director or
officer of the Company or any subsidiary thereof, including any vote that such individual may make as a director of the Company with respect to any matter presented to the Company’s board of directors. The Stockholder has executed this
Agreement solely in such Stockholder’s capacity as the record and/or beneficial owner of the Covered Shares and no action taken by the Stockholder in such Stockholder’s capacity as a director or officer of the Company or any subsidiary
thereof shall be deemed to constitute a breach of any provision of this Agreement. 
 Section 4.5 Other Obligations.
From and after the date of this Agreement until the termination hereof in accordance with its terms pursuant to Section 5.1 hereof, the Stockholder agrees (a) not to, and to cause any investment banker, attorney or other advisor or
representative of such Stockholder not to, directly or indirectly, solicit, initiate, knowingly encourage or facilitate, or furnish or disclose non-public information relating to the Company in furtherance of, any inquiries or the making of any
Alternative Proposal, or negotiate, explore or otherwise engage in discussions with any Person with respect to any Alternative Transaction, or approve, endorse or recommend any Alternative Transaction, or enter into any agreement, arrangement or
understanding with respect to any Alternative Transaction and (b) not to take any action which makes, or would reasonably be expected to make, any representation or warranty of such Stockholder herein untrue or incorrect in a material respect.
The Stockholder shall notify Parent promptly of any such inquiries, proposals or offers received by, or any such discussions or negotiations sought to be initiated or continued with, the Stockholder or, to the Stockholder’s knowledge, any of
its representatives, indicating the name of such Person and providing to Parent a summary of the material terms of such proposal or offer for an Alternative Transaction. Notwithstanding the foregoing, the Stockholder shall be permitted to engage in
discussions or negotiations with, or furnish or disclose non-public information relating to the Company to, any Person or group of related Persons that has made an Alternative Proposal if, and only to the

  

 -7- 

 
extent that, the Company is permitted under Section 4.3(b) of the Merger Agreement to engage in discussions or negotiations with, or to furnish or disclose non-public information to, such
Person or group of related Persons.

 -9- 

 
written consent of the other party, except that Parent may assign all or any of its rights and obligations hereunder to an affiliate; provided, however, that no such assignment

with any of the covenants, agreements or conditions contained herein which may legally be waived. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on
behalf of such party. 
 Section 5.9 Parties in Interest. This Agreement shall be binding upon and inure solely to
the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. However, if after
the execution hereof and before the Termination Date the Stockholder should die or become incapacitated, this Agreement shall be binding on the Stockholder’s estate or other legal representative. 
 Section 5.10 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of

 Section 5.11 Specific Performance; Submission To Jurisdiction. (a) The parties agree that irreparable damage
would occur if 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 each of the parties shall be entitled (in addition to any other remedy that
