WHEREAS, concurrently with the execution of this Voting Agreement, the Company and Purchaser have entered into an Agreement and Plan of

“Merger”); 
 WHEREAS, as of the date hereof, the Stockholder owns beneficially or of record or has the power
to vote, or direct the vote of, 34,755,329 shares of Company Common Stock (as defined below); 
 WHEREAS, the Merger Agreement
is required under Section 251 of the Delaware General Corporation Law (the “DGCL”) to be adopted by the affirmative vote of the holders of a majority of the shares of the Company’s common stock entitled to vote on such
matter; and 
 WHEREAS, as a condition to the willingness of Purchaser to enter into the Merger Agreement, and in order to
induce Purchaser to enter into the Merger Agreement, the Stockholder has agreed to enter into this Voting Agreement. 
 NOW,
THEREFORE, in consideration of the premises and of the mutual agreements and covenants set forth herein and in the Merger Agreement and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, and
intending to be legally bound hereby, the parties hereto agree as follows: 
 ARTICLE I 

DEFINITIONS 
 1.1 Capitalized Terms. Capitalized terms used but not defined in this Voting Agreement shall have the meanings ascribed to them in the Merger Agreement. 

1.2 Other Definitions. For purposes of this Voting Agreement: 

(a) “Beneficially Own”, “Beneficial Ownership” or “beneficial owner” with respect to
any Company Common Stock means having “beneficial ownership” of such securities (as determined pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), including pursuant to any
agreement, arrangement or understanding, whether or not in writing. Without duplicative counting of the same securities by the same holder, securities Beneficially Owned by a Person shall include securities Beneficially Owned by all other Persons
who are Affiliates of such Person and who together with such Person would 

  
 1 








 
constitute a “group” within the meaning of Section 13(d)(3) of the Exchange Act, but excluding any Stockholder’s Shares that may be owned by employees of Stockholder or its
Affiliates in their capacity as directors of the Company. 
 (b) “Company Common Stock” means the common stock
of the Company, no par value. 
 (c) “Shares” means shares of Company Common Stock. 

(d) “Stockholder’s Shares” means all shares of Company Common Stock held of record or Beneficially Owned by the
Stockholder, whether currently issued and outstanding or hereinafter acquired, including, without limitation, any Company Stock Options or Company Awards held of record or Beneficially Owned by the Stockholder or any New Shares. 

ARTICLE II 

TRANSFER AND VOTING OF SHARES 
 2.1 No Transfer of Shares. Stockholder shall not, directly or indirectly, (A) sell, pledge, encumber, assign, transfer or otherwise dispose of any or all of the Stockholder’s Shares or
any interest in the Stockholder’s Shares, (B) deposit the Stockholder’s Shares or any interest in the Stockholder’s Shares into a voting trust or enter into a voting agreement or arrangement with respect to any of his, her or its
Shares or grant any proxy or power of attorney with respect thereto or (C) enter into any contract, commitment, option or other arrangement or undertaking with respect to the direct or indirect acquisition or sale, assignment, pledge,
encumbrance, transfer or other disposition (whether by actual disposition or effective economic disposition due to hedging, cash settlement or otherwise) of any of the Stockholder’s Shares (any such action in clause (i), (ii) or
(iii) above, a “transfer”). Notwithstanding anything to the contrary in the foregoing sentence, this Section 2.1 shall not prohibit a transfer of Stockholder’s Shares by the Stockholder (i) if the Stockholder is
an individual, (A) to any member of the Stockholder’s immediate family or to a trust for the benefit of the Stockholder or any member of the Stockholder’s immediate family, or (B) upon the death of the Stockholder to such
Stockholder’s heirs, or (ii) if the Stockholder is a partnership or limited liability company, to one or more partners or members of the Stockholder or to an Affiliate under common control with the Stockholder, as applicable;
provided, however, that in each case a transfer shall be permitted only if as a condition precedent to the effectiveness of such transfer, the transferee agrees in a writing, satisfactory in form and substance to Purchaser, to be bound
by all of the terms of this Voting Agreement. For the avoidance of doubt, subject to any changes after the date hereof not contemplated by the Merger Agreement that would affect the status of Stockholder as a non-affiliate of Purchaser within the
meaning of Rule 144 under the Securities Act, Purchaser agrees that it will not instruct the transfer agent to place any securities Laws transfer restriction legend on the shares of common stock of Purchaser held by Stockholder and will not advise
its transfer agent that there are any restrictions on the transfer of shares of common stock of Purchaser by Stockholder under the securities Laws. 
 2.2 Vote in Favor of the Merger and Related Matters. The Stockholder, solely in the Stockholder’s capacity as a stockholder of the Company (and not, if applicable, in the


  
 2 








 
Stockholder’s capacity as an officer or director of the Company), irrevocably and unconditionally agrees that, from and after the date hereof until the Expiration Date, at any meeting of the
stockholders of the Company or any adjournment thereof, or in connection with any action by written consent of the stockholders of the Company, the Stockholder shall: 
 (a) appear at each such meeting or otherwise cause the Stockholder’s Shares Beneficially Owned or owned of record by the Stockholder to be counted as present thereat for purposes of calculating a
quorum; 
 (b) vote (or cause to be voted), in person or by proxy, or deliver a written consent (or cause a consent to be
delivered) covering, all of the Stockholder’s Shares: (i) in favor of, and will otherwise support, the adoption of the Merger Agreement and approval of the Merger, the Subsequent Mergers and the other transactions contemplated by the
Merger Agreement, including, but not limited to, any stockholder vote required by the Amended and Restated Certificate of Incorporation of the Company (the “Certificate”) and Section 251 of the DGCL, (ii) in favor of any
other matter reasonably relating to the consummation or facilitation of, or otherwise in furtherance of, the transactions contemplated by the Merger Agreement and (iii) except for the Merger, the Subsequent Mergers and the Merger Agreement,
against, and not otherwise support, any Company Acquisition Proposal or any other action, agreement or transaction submitted for approval of the Company’s stockholders that is intended, or would reasonably be expected, to materially impede,
interfere or be inconsistent with, delay, postpone, discourage or materially and adversely affect consummation of the Merger, the Subsequent Mergers or this Agreement, including any extraordinary transaction, including any merger, consolidation,
sale of assets, recapitalization or other business combination involving the Company or any of its Subsidiaries or any other action or agreement that would reasonably be expected to result in a material breach of any covenant, representation or
warranty or any other obligation or agreement of the Company under the Merger Agreement or that would reasonably be expected to result in any of the conditions to the Company’s obligations under the Merger Agreement not being fulfilled or
satisfied. Except as set forth in this Section 2.2, nothing in this Voting Agreement shall limit the right of the Stockholder to vote in favor of, against or abstain with respect to any matter presented to the Company’s stockholders,
including in connection with the election of directors proposed by the Company or Purchaser or by a third party not in connection with a Company Acquisition Proposal proposed by such third party. 

2.3 Termination. This Voting Agreement and the obligations of the Stockholder pursuant to this Voting Agreement shall terminate
upon the earlier to occur of (a) such date and time as the Merger Agreement shall have been validly terminated pursuant to its terms, (b) the date of any amendment, modification, change or waiver to any provision of the Merger Agreement
that reduces the amount or changes the form of the Merger Consideration (subject to adjustment in accordance with the terms of the Merger Agreement) and (c) such date and time as the Merger shall have become effective in accordance with the
terms and provisions of the Merger Agreement (such earlier date, the “Expiration Date”); provided, however, that if the Merger shall become effective, the Purchaser’s obligations pursuant to the last sentence of
Section 2.1 shall survive such termination. 
 2.4 Stockholder Capacity. The parties acknowledge that this
Voting Agreement is entered into by Stockholder in his or its capacity as owner of the Stockholder’s Shares and that 

  
 3 








 
nothing in this Voting Agreement shall in any way restrict, limit or prohibit any affiliate or representative of Stockholder from exercising his or her fiduciary duties in his or her capacity as
a director of the Company.
