contemplated hereby, shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without giving effect to principles or rules of conflicts of laws to the extent such principles or rules are not mandatorily applicable

the parties (i) consents to submit itself, and hereby submits itself, to the personal jurisdiction of the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction, any state or federal court located
in the State of Delaware having subject matter jurisdiction, in the event any dispute arises out of this Agreement or any of the transactions contemplated by this Agreement, (ii) agrees that it will not attempt to deny or defeat such personal
jurisdiction by motion or other request for leave from any such court, and agrees not to plead or claim any objection to the laying of venue in any such court or that any judicial proceeding in any such court has been brought in an inconvenient
forum, (iii) agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the Court of Chancery of the State of Delaware or, if such court does not have

impaired or invalidated, so long as the economic and legal substance of the transactions contemplated hereby, taken as a whole, are not affected in a manner materially adverse to any Party hereto. Upon such a determination, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to

 17. Enforcement. The rights and remedies of the parties shall be cumulative with and
not exclusive of any other remedy conferred hereby. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that 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 the parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the
terms and provisions of this Agreement, including each Stockholder’s obligations to vote its Covered Shares as provided in this Agreement, in the Court of Chancery of the State of Delaware or, if under applicable law exclusive jurisdiction over
such matter is vested in the federal courts, any state or federal court located in the State of Delaware, without proof of actual damages or otherwise (and each Party hereby waives any requirement for the securing or posting of any bond in
connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. 
 18.
Severability. If any term or other provision of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void, unenforceable or against its regulatory policy, the remainder of the terms and provisions of
this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated, so long as the economic and legal substance of the transactions contemplated hereby, taken as a whole, are not affected in a manner
materially adverse to any Party hereto. Upon such a determination, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner in
order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible. 
 19.
Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement, it being understood that each Party need not sign the same counterpart. This Agreement shall become
effective when each Party shall have received a counterpart hereof signed by all of the other parties. Signatures delivered electronically or by facsimile shall be deemed to be original signatures. 

20. Interpretation and Construction. The words “hereof,” “herein” and “hereunder” and words of like import
used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The descriptive headings used herein are inserted for convenience of reference only and are not intended to be part of or to
affect the meaning or interpretation of this Agreement. References to Sections are to Sections of this Agreement unless otherwise specified. Any singular term in this Agreement shall be deemed to include the plural, and any plural term the singular.
The definitions contained in this Agreement are applicable to the masculine as well as to the feminine and neuter genders of such term. Whenever the words “include,” “includes” or “including” are used in this Agreement,
they shall be deemed to be followed by the words “without limitation,” whether or not they are in fact followed by those words or words of like import. “Writing,” “written” and comparable terms refer to printing, typing
and other means of reproducing words (including electronic media) in a visible form. References to any statute shall be deemed to refer to such statute and to any rules or regulations promulgated thereunder. References to any person include the
successors and permitted assigns of that person. References from or through any date mean, unless otherwise specified, from and including such date or through and including such date, respectively. In the event an ambiguity or question of intent or
interpretation arises, this Agreement will be construed as if drafted jointly by the Parties, and no presumption or burden of proof will arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement.

 21. Capacity as a Stockholder or Proxy holder. Notwithstanding anything herein to the
contrary, the Stockholder or proxy holder signs this Agreement solely in the Stockholder’s or Proxy holder’s capacity as a stockholder or proxy holder of the Company, and not in any other capacity and this Agreement shall not limit,
prevent or otherwise affect the actions of the Stockholder, proxy holder or any Affiliate, employee or designee of the Stockholder or proxyholder, or any of their respective Affiliates in his or her capacity, if applicable, as an officer or director
of the Company (or any Subsidiary of the Company) or any other Person, including in the exercise of his or her fiduciary duties as a director or officer of the Company or any Subsidiary of the Company. No Stockholder shall be liable or responsible
for any action undertaken by or any breach, default, or violation of any representation, warranty, covenant or agreement by any other Stockholder that is also a Party hereto or the Company and each Stockholder shall solely be required to perform its
obligations hereunder in its individual capacity. 
 22. Affiliate Agreements. The Stockholder irrevocably and unconditionally hereby
agrees and consents to the termination of all affiliate arrangements indicated for termination as set forth in Schedule 2 hereto, to which the Stockholder is party, effective as of the Effective Time without any liability or obligation to the
