Agreement by written notice from Parent to Stockholder (such earliest date, the “Expiration Date”).

Section III.3.Effect of Termination. In the event this Agreement is validly terminated as provided in Section 3.2, this Agreement shall immediately become void and no Party will have any further obligations or liabilities under this Agreement, except that nothing in this Section 3.3 shall relieve any Party from liability for fraud or any Willful Breach of this Agreement prior to such termination, which liabilities shall survive the termination of this Agreement. The provisions of this Section 3.3 and of Article VII will survive any termination of this Agreement.

Section III.4.Stockholder Capacity. The Parties acknowledge that this Agreement is entered into by Stockholder in his, her, or its capacity as owner of the Owned Shares and not, if applicable, in such Stockholder’s capacity as a director, officer or employee of the Company, and that nothing in this Agreement is intended to restrict or affect any action or inaction of Stockholder or any representative of Stockholder, as applicable, serving on the Company Board or on the board of directors (or similar body) of any Subsidiary of the Company or as an officer or fiduciary of the Company or any Subsidiary of the Company, acting in such person’s capacity as a director or officer of the Company or any Subsidiary of the Company, or prevent or be construed to create any obligation on the part of any director or officer of the Company or any Subsidiary of the Company from taking any action in his or her capacity as such director or officer, and no action taken in any such capacity as an officer or director of the Company or any Subsidiary of the Company shall be deemed to constitute a breach of this Agreement.

Section VII.1.Entire Agreement; No Third-Party Beneficiaries.

(a)This Agreement (together with Schedule A) and the Merger Agreement constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, between or among the Parties or their Affiliates, or any of them, with respect to the subject matter hereof.

(b)Each Party agrees that (i) their respective representations, warranties, covenants and agreements set forth in this Agreement are solely for the benefit of the other Parties, in accordance with and subject to the terms of this Agreement and (ii) this Agreement is not intended to, and does not, confer upon any Person other than the Parties any rights or remedies under this Agreement, including the right to rely upon the representations and warranties set forth in this Agreement.

Section VII.2.Assignment. Neither this Agreement nor any of the rights, interests, or obligations under this Agreement may be assigned, by operation of law or otherwise, by any Party, other than in connection with a Transfer of Owned Shares pursuant to the requirements of Section 3.1, without the prior written consent of each of the other Parties. Any purported assignment without such consent shall be void. Subject to the preceding sentences, this

Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective successors and assigns.

Section VII.3.Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon any determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner to the end that transactions contemplated by this Agreement are fulfilled to the extent possible.

Section VII.4.Specific Performance. The Parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached or threatened to be breached and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that, at any time prior to the termination of this Agreement pursuant to Section 3.2, the Parties shall be entitled to obtain an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the performance of the terms and provisions of this Agreement, in any court referred to in Section 7.6, without proof of actual damages (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, including monetary damages. The Parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any breach or threatened breach of this Agreement.

Section VII.5.Governing Law. This Agreement, including all matters of construction, and all Claims (whether in contract or in tort or otherwise, whether at law or in equity) that may be based on, arise out of or relate to this Agreement or the negotiation, execution, performance or subject matter of this Agreement, shall be governed by and construed in accordance with the Laws of the State of Delaware applicable to contracts executed and to be performed in that State.

Section VII.6.Jurisdiction; Venue; Service of Process. Each of the Parties hereby (i) expressly and irrevocably submits to the exclusive personal jurisdiction of (A) the Court of Chancery of the State of Delaware or (B) if such Court of Chancery lacks subject-matter jurisdiction, the United States District Court for the District of Delaware, in the event any dispute arises out of this Agreement, (ii) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, and (iii) agrees that it shall not bring any action relating to this Agreement in any court other than (A) the Court of Chancery of the State of Delaware or (B) if such Court of Chancery lacks subject-matter jurisdiction, the United States District Court for the District of Delaware; provided that each of the Parties has the right to bring any proceeding for enforcement of a judgment entered by such court in any other court or jurisdiction. Each Party further agrees that service of any process, summons, notice, or document by U.S. registered mail to the respective addresses set forth in Section 7.8 shall be effective service of process for any Claim brought against such Party in any such court. The foregoing, however, will not limit the right of a Party to effect service of process on any other Party by any other

legally available method. Each Party hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any action or proceeding arising out of or relating to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the courts in Delaware as described herein for any reason, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) that this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

Section VII.7.Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING ARISING OUT OF, RELATING TO OR IN CONNECTION WITH THIS AGREEMENT, THE OFFER OR THE MERGER. EACH PARTY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SUIT OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS Section 7.7.
