If any involuntary Transfer of all or any portion of the Subject Shares or Subject Equity Awards of such Stockholder shall occur (including, if applicable, a sale by a Stockholder’s trustee in any bankruptcy, or a sale to a Merger Sub at any creditor’s or court sale), the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold such Subject Shares subject to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until valid termination of this Agreement in accordance with Section 5.2. From and after the date hereof until this Agreement is validly terminated in accordance with Section 5.2, each Stockholder agrees that it shall not, and shall cause each of such Stockholder’s Affiliates not to, become a member of a “group” (as defined under Section 13(d) of the Exchange Act) with respect to any securities in the Company for the purpose of opposing or competing with or taking any actions inconsistent with the transactions contemplated by the Merger Agreement. Notwithstanding the foregoing, each Stockholder may make Transfers of Subject Shares and Subject Equity Awards of such Stockholder (i) to any “Permitted Transferee” (as defined below), in which case any such transferred Subject Shares or Subject Equity Awards shall continue to be bound by this Agreement and provided that any such Permitted Transferee agrees in writing to be bound by the terms and conditions of this Agreement prior to the consummation of any such Transfer, or (ii) as Parent may otherwise agree in writing in its sole discretion. A “Permitted Transferee” means, with respect to any Stockholder, (A) a spouse, lineal descendant or antecedent, brother or sister, adopted child or grandchild or the spouse of any child, adopted child, grandchild or adopted grandchild of such Stockholder, (B) any charitable organization described in Section 170(c) of the Code, (C) any trust, the beneficiaries of which include only the Persons named in clause (A) or (B) of this definition, or (D) any corporation, limited liability company or partnership, the stockholders, members and general or limited partners of which include only the Persons named in clause (A) or (B) of this definition.

(b) All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the State of Delaware lacks subject matter jurisdiction over any Action, any state or federal court within the State of Delaware).

The parties hereto agree that a final Judgment in any such Action shall be conclusive and may be enforced in other jurisdictions by suit on the Judgment or in any other manner provided by applicable Law; provided, however, that nothing in the foregoing shall restrict any parties’ rights to seek any post-judgment relief regarding, or any appeal from, a final trial court Judgment.

(c) EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT 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 LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVER, (C) IT MAKES SUCH WAIVER VOLUNTARILY AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 5.6.

Section 5.7 Counterparts. This Agreement may be executed in one or more counterparts (including by DocuSign, facsimile or electronic mail with .pdf attachments), each of which shall be deemed to be an original but all of which taken together shall constitute one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the parties hereto and delivered to the other parties hereto.

Section 5.8 Entire Agreement. This Agreement (together with Schedule I and the other documents delivered pursuant hereto) constitutes the entire agreement, and supersedes all other prior agreements and understandings, both written and oral, among the parties hereto and their Affiliates, or any of them, with respect to the subject matter of this Agreement.

Section 5.9 Severability. If any term, condition or other provision of this Agreement is determined by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule of Law or public policy (as determined by a final judgement), all other terms, provisions and conditions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term, condition or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable Law.

Section 5.10 Specific Enforcement. The parties hereto agree that irreparable damage for which monetary relief, even if available, would not be an adequate remedy, would occur in the event that any provision of this Agreement is not performed in accordance with its specific terms or is otherwise breached, including if the parties fail to take any action required of them hereunder to consummate this Agreement. The parties acknowledge and agree that (a) the parties shall be entitled to an injunction or injunctions, specific performance or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the courts described in Section 5.6(b) without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement and (b) the right of specific enforcement is an integral part of this Agreement and without that right parties would not have entered into this Agreement. The parties hereto agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason, and not to assert that a remedy of monetary damages would provide an adequate remedy or that the parties otherwise have an adequate remedy at law. The parties acknowledge and agree that any party in seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 5.10 shall not be required to provide any bond or other security in connection with any such order or injunction.

Section 5.11 Mutual Drafting.

Section 5.12 Further Assurances. Parent, Merger Sub and each Stockholder will execute and deliver, or cause to be executed and delivered, all further documents and instruments and use their respective reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws and regulations, to perform their respective obligations under this Agreement.
