5.7                                 Governing Law; Venue.

(a)                                  This Agreement and all claims or causes of action (whether at Law, in contract, in tort or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance hereof shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to conflicts of laws principles (whether of the State of Delaware or any other jurisdiction) that would result in the application of the Law of any other state.

(b)                                 Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Delaware Court of Chancery, or, if (and only if) such court lacks subject matter jurisdiction, the Federal court of the United States of America sitting in the State of Delaware, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the agreements delivered in connection herewith or the transactions contemplated hereby or thereby or for recognition or enforcement of any judgment relating thereto, and each of the parties hereby irrevocably and unconditionally (i) agrees not to commence any such action or proceeding except in the Delaware Court of Chancery, or, if (and only if) such court lacks subject matter jurisdiction, the Federal court of the United States of America sitting in the State of Delaware, and any appellate court from any thereof, (ii) agrees that any claim in respect of any such action or proceeding shall be heard and determined in the Delaware Court of Chancery, or, if (and only if) such court lacks subject matter jurisdiction, the federal court of the United States of America sitting in the State of Delaware, and any appellate court from any thereof, (iii) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any such action or proceeding in the Delaware Court of Chancery, or, if (and only if) such court lacks subject matter jurisdiction, the federal court of the United States of America sitting in State of Delaware, and any appellate court from any thereof, (iv) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in the Delaware Court of Chancery, or, if (and only if) such court lacks subject matter jurisdiction, the federal court of the United States of America sitting in the State of Delaware, and any appellate court from any thereof, (v) waives, to the fullest extent permitted by Law, any claim that it is not personally subject to

the jurisdiction of the Delaware Court of Chancery, or, if (and only if) such court lacks subject matter jurisdiction, the federal court of the United States of America sitting in Delaware, and any appellate court from any thereof for any reason other than the failure to serve in accordance with this Agreement, (vi) waives, to the fullest extent permitted by Law, any claim that it or its property is exempt or immune from jurisdiction of the Delaware Court of Chancery, or, if (and only if) such court lacks subject matter jurisdiction, the Federal court of the United States of America sitting in the State of Delaware 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 (vii) waives, to the fullest extent permitted by Law, any claim that this Agreement, or the subject mater hereof, may not be enforced in or by such courts.  Each of the parties hereto agrees that a final judgment in any such 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.  Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 5.6.  Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by Law.

(c)                                  EACH PARTY HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT.

5.8                                 Counterparts.  This Agreement may be executed in two or more counterparts, each of which shall be deemed an original but all of which together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties hereto and delivered to the other parties, it being understood that all parties need not sign the same counterpart.  This Agreement may be executed and delivered by facsimile transmission.

5.9                                 Descriptive Headings.  The descriptive headings used herein are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of this Agreement.

5.10                           Severability.  Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.  If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified.  In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

5.11                           Specific Performance.  The parties hereto agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy would occur in the event that any provision of this Agreement were not performed in accordance with the terms hereof and that, prior to the valid termination of this Agreement pursuant to Section 5.1, the parties hereto shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms hereof, in addition to any other remedy at law or equity.

5.12                           Non-Recourse.  No past, present or future director, officer, employee, incorporator, member, partner, stockholder, agent, attorney or representative of any party hereto or any of their respective affiliates shall have any liability (whether in contract or in tort) for any obligations or liabilities of such party arising under, in connection with or related to this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby.
