Section 5.5 Severability. If any term or other provision of this Agreement is held by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term 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 in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the party or parties to be bound thereby. The failure of any party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

Section 5.9 Parties in Interest.

Section 5.11 Specific Performance; Submission To Jurisdiction. The parties 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. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions, without the necessity of proving the inadequacy of money damages as a remedy and without the necessity of posting any bond or other security, to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in Court of Chancery or other courts of the State of Delaware, this being in addition to any other remedy to which such party is entitled at law or in equity. In addition, each of the parties hereto (i) consents to submit itself to the personal jurisdiction of the Court of Chancery or other courts of the State of Delaware in the event any dispute arises out of this Agreement or any of the transactions contemplated by 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 such court, (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 or other courts of the State of Delaware and (iv) to the fullest extent permitted by Law, consents to service being made through the notice procedures set forth in Section 5.4.
