proceeding pending against, or, to the knowledge of the Stockholder, overtly threatened against or affecting, the Stockholder or any of its, his or her properties or assets (including the Shares) that could reasonably be expected to impair the

identity and ownership of Shares and the nature of the Stockholder’s commitments, arrangements and understandings under this Agreement; provided that, Parent shall provide the Stockholder, the Company and Dechert LLP, Company counsel,
reasonable opportunity to review and comment on such disclosure and Parent shall give reasonable consideration to any comments made by the Stockholder, the Company or Dechert LLP. 
 14. Further Assurances. Subject to the terms and conditions of this Agreement, (a) the Stockholder shall use commercially reasonable efforts

Agreement shall relieve either party hereto from liability, or otherwise limit the liability of either party hereto, for any material breach, prior to the Expiration Date, of any covenant contained in this Agreement. 
 16. Miscellaneous. 
 (a) Successors
and Assigns. All covenants and agreements and other provisions set forth in this Agreement and made by or on behalf of any of the parties hereto shall bind and inure to the benefit of the successors, heirs and permitted assigns of such party,
whether or not so expressed. None of the parties may assign, transfer or delegate any of their respective rights or obligations under this Agreement, by operation of law or otherwise, without the consent in writing of the Parent and the Stockholder
provided, that (i) Parent may, without obtaining the prior written consent of the Stockholder, assign any of its rights, or delegate any of its obligations under this Agreement to any affiliate of Parent to which Parent has assigned its rights
under, and in accordance with, the Merger Agreement, provided, that such affiliate agrees in writing, reasonably satisfactory in form and substance to the Stockholder, to be bound by all of the terms of this Agreement, and (ii) the Stockholder
may, without obtaining the prior written consent of Parent, assign any of its rights, or delegate any of its obligations under this Agreement to (X) any successor of the Stockholder by merger or otherwise, or (Y) the purchaser of all or
substantially all of the assets (if such assets include all of the Shares) of the Stockholder and the purchaser agrees in a writing, reasonably satisfactory in form and substance to Parent, to be bound by all of the terms of the Agreement; and
provided further, that such assignment or delegation has been made in good faith and has not been made for the purpose of avoiding or frustrating any of the assigning or delegating party’s obligations hereunder. No such assignment or delegation
shall constitute or result in a release of the assigning or delegating party from any of its obligations under this Agreement, and following any such assignment or delegation, the assigning or delegating party shall remain jointly and severally
liable with the assignee or delegee for any breach of the Agreement by the assignee or delegee. Each of Parent and the Stockholder shall execute such acknowledgements of such assignments in such forms as the other may from time to time reasonably
request. Any purported assignment or delegation of rights or obligations in violation of this Section 16(a) shall be void and of no force or effect.

 (b) Amendments; No Waiver. Subject to applicable law, any provision of this Agreement may be
amended or waived, but only if such amendment or waiver is in writing and signed, in the case of an amendment, by each of the parties hereto, or in case of a waiver, by each party against whom the waiver is to be effective. No course of dealing and
no failure or delay on the part of any party hereto in exercising any right, power or remedy conferred by this Agreement shall operate as a waiver thereof or otherwise prejudice such party’s rights, powers and remedies. The failure of any of
the parties to this Agreement to require the performance of a term or obligation under this Agreement or the waiver by any of the parties to this Agreement of any breach hereunder shall not prevent subsequent enforcement of any term or obligation or
be deemed a waiver of any subsequent breach hereunder. No single or partial exercise of any right, power or remedy conferred by this Agreement shall preclude any other or further exercise thereof or the exercise of any other right, power or remedy.

 (c) Specific Performance. The parties hereto agree that irreparable damage would occur to the parties in the event that the
provisions contained in this Agreement were not performed by the other parties in accordance with its specific terms or were otherwise breached by the other parties. It is accordingly agreed that the parties shall be entitled to an injunction or
injunctions, without the posting of any bond, to prevent breaches of this Agreement by the other parties and to enforce specifically the terms and provisions of this Agreement in any court of the United States or any state having jurisdiction, this
being in addition to any other remedy to which the parties are entitled at law or in equity.

and irrevocably consents and submits to the jurisdiction of each such court, and each appellate court located in the State of Delaware, in connection with any such proceeding; (ii) agrees that each such court shall be deemed to be a convenient
forum; and (iii) agrees not to assert, by way of motion, as a defense or otherwise, in any such proceeding commenced in any such court, any claim that such party is not subject personally to the jurisdiction of such court, that such proceeding
has been brought in an inconvenient forum, that the venue of such proceeding is improper or that this Agreement or the subject matter of this Agreement may not be enforced in or by such court. 
 (g) Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation and execution of this
Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

impaired or affected, it being intended that each of parties’ rights and privileges shall be enforceable to the fullest extent permitted by Applicable Law, and any such invalidity, illegality and unenforceability in any jurisdiction shall not

another provision (instead of the provision held to be invalid, illegal or unenforceable) that is valid, legal and enforceable and carry out the intentions of the parties hereto under this Agreement and, in the event that such court does not
exercise such power, the parties hereto shall negotiate in good faith in an attempt to agree to another provision (instead of the provision held to be invalid, illegal or unenforceable) that is valid, legal and enforceable and carries out the
parties’ intentions to the greatest lawful extent under this Agreement. 
 (j) Interpretation. For purposes of this Agreement,
the following rules of interpretation apply:

next succeeding Business Day.

Agreement to any “Section,” “Schedule” or “Exhibit” are to the corresponding Section, Schedule or Exhibit of this Agreement. 
 (iv) Whenever the words “include,” “includes” or “including” are used in this Agreement they shall be deemed to be followed by the words “without limitation.” As used in this

the respective meanings ascribed to them in the Support Agreement. 
 The attorneys and proxies named above, and each of them, are hereby
authorized and empowered by the undersigned, at any time prior to the Expiration Date, to act as the undersigned’s attorney and proxy to vote the Shares, and to exercise all voting, consent and similar rights of the undersigned with respect to
the Shares (including, without limitation, the power to execute and deliver written consents) at every annual, special, adjourned or postponed meeting of stockholders of the Company and, in the event the Company determines to solicit written
consents in lieu of any such meeting, in every such written consent: (i) in favor of the Merger, the adoption, execution and delivery by the Company of the Merger Agreement and the approval of the terms thereof, and each of the actions
contemplated by the Merger Agreement and this Agreement and any actions required in furtherance hereof or thereof; (ii) against approval of any proposal made in opposition to, or in competition with, consummation of the Merger or any other

undersigned agrees that the Shares that are entitled to be voted shall be voted (or cause to be voted) as set forth in this paragraph whether or not the undersigned’s vote, consent or other approval is sought on only one or any combination of
the matters set forth in (i)-(iii) above and at any time following the date hereof. 
 The attorneys and proxies named above may not
exercise this Irrevocable Proxy on any other matter. The Stockholder may vote the Shares on all other matters. 
 Any obligation of the
undersigned hereunder shall be binding upon the successors and assigns of the undersigned.

of no further force and effect, automatically upon the Expiration Date.
