In the event the undersigned has any Claim against the Company under this Agreement or otherwise, the undersigned shall pursue such Claim solely against the Company and its assets held outside of the Trust Account and not against the Trust Account or any monies or other assets held in the Trust Account.

9. Governing Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the principles of conflicts of law thereof that would require the application of the laws of any jurisdiction other than New York. The undersigned consents to the non-exclusive jurisdiction of the federal courts whose districts encompass any part of the City of New York or the state courts of the State of New York sitting in the City of New York in connection with any dispute arising under this Agreement and hereby waives, to the maximum extent permitted by law, any objection, including any objection based on forum non conveniens, to the bringing of any such proceeding in such jurisdictions.

The parties agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof, and, accordingly, that the parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in any action brought in the federal courts whose districts encompass any part of the City of New York or the state courts of the State of New York sitting in the City of New York, without proof of actual damages or otherwise, in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereby further waives (a) any defense in any action for specific performance that a remedy at law would be adequate and (b) any requirement under any law to post security or a bond as a prerequisite to obtaining equitable relief.

11. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO (ON BEHALF OF ITSELF AND ITS SUBSIDIARIES) HEREBY KNOWINGLY, INTENTIONALLY AND VOLUNTARILY IRREVOCABLY WAIVES ANY AND ALL RIGHTS TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

13. Entire Agreement. This Agreement along with the Investor Questionnaire attached hereto constitutes the entire agreement and supersedes all prior agreements, understandings and representations and warranties, both written and oral, among the parties hereto with respect to the subject matter hereof. Notwithstanding anything in this Agreement to the contrary, nothing herein shall be deemed to modify, amend, or otherwise affect the rights and obligations of the Company set forth in the Merger Agreement.

14. Severability. If any term, provision, covenant or restriction 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, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or unenforceable provision or portion thereof shall be interpreted to be only so broad as is enforceable.

This Agreement may be executed in two or more counterparts, all of which shall be considered one and the same agreement and shall become effective when two or more counterparts have been signed by each of the parties and delivered to the other parties (including by facsimile or via portable document format (.pdf)), it being understood that all parties need not sign the same counterpart.

16. Expiration.
