4.             Further Assurances.  It is the intent of the Parties that all of FX’s right, title and interest in, to and under the Option Agreement be conveyed, granted, transferred, assigned and delivered to Braeburn as set forth herein.  From time to time after the date hereof, at the request of Braeburn or FX, but without further consideration, Braeburn or FX, as the case may be, will each execute and deliver to the other Party such other instruments of conveyance, assignment and transfer and take such other actions as Braeburn and/or FX reasonably may request in order to consummate the transactions contemplated herein.

5.             Governing Law.  This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdiction other than those of the State of Delaware.

6.             Consent to Jurisdiction.  Each of the Parties hereby irrevocably consents and agrees that any suit, action or proceeding (a “Proceeding”) arising in connection with any disagreement, dispute, controversy or claim arising out of or relating to this Agreement (a “Legal Dispute”) shall be brought only to the exclusive jurisdiction of the courts of the State of Delaware or the federal courts located in the State of Delaware.  The Parties agree that, after a Legal Dispute is before a court as specified in this Section 6 and during the pendency of the Legal Dispute before that court, all Proceedings with respect to the Legal Dispute or any other Legal Dispute, including any counterclaim, cross-claim or interpleader, shall be subject to the exclusive jurisdiction of that court.  Each of the Parties hereby waives, and agrees not to assert, as a defense in any Legal Dispute, that it is not subject thereto or that the Proceeding may not be brought or is not maintainable in that court or that its property is exempt or immune from execution, that the Proceeding is brought in an inconvenient forum or that the venue of the Proceeding is improper.  Each Party hereto agrees that a final judgment in any Proceeding described in this Section 6 after the expiration of any period permitted for appeal and subject to any stay during appeal shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable law.
