3. Miscellaneous.

(a) Governing Law; Jurisdiction. This Agreement, and all claims or causes of action (whether in contract, tort or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement) shall be governed by and construed in accordance with the law of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws. Each of the parties hereto hereby irrevocably and unconditionally (i) submits, for itself and its property, to the exclusive jurisdiction of the Delaware Court of Chancery (or, only if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, the Delaware Superior Court or the United States District Court for the District of Delaware), and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement), or for recognition or enforcement of any judgment, and agrees that all claims in respect of any such action or proceeding shall be heard and determined in such Delaware Court of Chancery (or, only if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, the Delaware Superior Court or the United States District Court for the District of Delaware), (ii) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement) in the Delaware Court of Chancery or in the Delaware Superior Court or the United States District Court for the District of Delaware, (iii) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court and (iv) agrees that a final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

(b) Waiver of Jury Trial. THE PARTIES HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY OR THE ACTIONS OF THE PARTIES IN THE NEGOTIATION, EXECUTION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE. THE PARTIES AGREE THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE TRIAL BY JURY AND THAT ANY ACTION OR PROCEEDING WHATSOEVER BETWEEN THEM RELATING TO THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY SHALL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.

(c) Assignment; Third Parties. This Agreement and all of the provisions hereof will be binding upon and inure to the benefit of the parties hereto and their respective heirs, successors and permitted assigns. This Agreement and all obligations of a Holder are personal to such Holder and may not be transferred or delegated at any time. Nothing contained in this Agreement shall be construed to confer upon any Person who is not a signatory hereto any rights or benefits, as a third-party beneficiary or otherwise.

(d) Specific Performance. The parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the parties hereto do not perform the provisions of this Agreement in accordance with its specified terms or otherwise breach or threaten to breach such provisions. The parties acknowledge and agree that the parties hereto shall be entitled, in addition to any other remedy to which they are entitled at law or in equity, to an injunction, specific performance and other equitable relief to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions hereof. Without limiting the foregoing, each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that (i) there is adequate remedy at law or (ii) an award of specific performance is not an appropriate remedy for any reason at law or in equity. Any party seeking an order or injunction to prevent breaches or threatened breaches and to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.

(e) Amendment; Waiver. Upon (i) the approval of a majority of the total number of directors serving on the Board of Directors of the Company who are not nominated or designated pursuant to contractual rights of Holders, (ii) the written consent of the Sponsor and (iii) the written consent of the Holders of a majority of the total Lock-Up Shares, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived by the Company, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects a Holder, solely in its capacity as a holder of Lock-Up Shares, shall require the consent of the Holder so affected. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.
