11.           Governing Law.  THIS AMENDMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY CONFLICT OF LAW PRINCIPLES (BUT GIVING EFFECT TO FEDERAL LAWS RELATING TO NATIONAL BANKS).

12.           Consent to Forum; Arbitration.

(a)           Forum.  EACH OBLIGOR HEREBY CONSENTS TO THE NON-EXCLUSIVE JURISDICTION OF ANY FEDERAL OR STATE COURT SITTING IN OR WITH JURISDICTION OVER THE STATE OF NEW YORK, IN ANY PROCEEDING OR DISPUTE RELATING IN ANY WAY TO THIS AMENDMENT, AND AGREES THAT ANY SUCH PROCEEDING SHALL BE BROUGHT BY IT SOLELY IN ANY SUCH COURT.  EACH OBLIGOR IRREVOCABLY WAIVES ALL CLAIMS, OBJECTIONS AND DEFENSES THAT IT MAY HAVE REGARDING SUCH COURT’S PERSONAL OR SUBJECT MATTER JURISDICTION, VENUE OR INCONVENIENT FORUM.  EACH PARTY HERETO IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 14.3.1 OF THE LOAN AGREEMENT.  Nothing herein shall limit the right of Agent or any Lender to bring proceedings against any Obligor in any other court, nor limit the right of any party to serve process in any other manner

3

permitted by Applicable Law.  Nothing in this Amendment shall be deemed to preclude enforcement by Agent of any judgment or order obtained in any forum or jurisdiction.

(b)           Arbitration.  Notwithstanding any other provision of this Amendment or any other Loan Document to the contrary, if for any reason a court having jurisdiction over an action among the parties relating in any way to any Obligations or Loan Documents does not uphold the waiver of jury trail contained in Section 13 or in any provision of any other Loan Document, any controversy or claim among the parties relating in any way to any Obligations or Loan Documents, including any alleged tort, shall at the request of any party hereto be determined by binding arbitration conducted in accordance with the United States Arbitration Act (Title 9 U.S. Code).  Arbitration proceedings will be determined in accordance with the Act, the then-current rules and procedures for the arbitration of financial services disputes of the American Arbitration Association (“AAA”), and the terms of this Section.  In the event of any inconsistency, the terms of this Section shall control.  If AAA is unwilling or unable to serve as the provider of arbitration or to enforce any provision of this Section, Agent may designate another arbitration organization with similar procedures to serve as the provider of arbitration.  The arbitration proceedings shall be conducted in New York.  The arbitration hearing shall commence within 90 days of the arbitration demand and close within 90 days thereafter.  The arbitration award must be issued within 30 days after close of the hearing (subject to extension by the arbitrator for up to 60 days upon a showing of good cause), and shall include a concise written statement of reasons for the award.  The arbitrator shall give effect to applicable statutes of limitation in determining any controversy or claim, and for these purposes, service on AAA under applicable AAA rules of a notice of claim is the equivalent of the filing of a lawsuit.  Any dispute concerning this Section or whether a controversy or claim is arbitrable shall be determined by the arbitrator.  The arbitrator shall have the power to award legal fees to the extent provided by this Agreement.  Judgment upon an arbitration award may be entered in any court having jurisdiction.  The institution and maintenance of an action for judicial relief or pursuant to a provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for judicial relief.  No controversy or claim shall be submitted to arbitration without the consent of all parties if, at the time of the proposed submission, such controversy or claim relates to an obligation secured by Real Estate, but if all parties do not consent to submission of such a controversy or claim to arbitration, it shall be determined as provided in the next sentence.  At the request of any party, a controversy or claim that is not submitted to arbitration as provided above shall be determined by judicial reference; and if such an election is made, the parties shall designate to the court a referee or referees selected under the auspices of the AAA in the same manner as arbitrators are selected in AAA sponsored proceedings and the presiding referee of the panel (or the referee if there is a single referee) shall be an active attorney or retired judge; and judgment upon the award rendered by such referee or referees shall be entered in the court in which proceeding was commenced.  None of the foregoing provisions of this Section shall limit the right of Agent or Lenders to exercise self-help remedies, such as setoff, foreclosure or sale of any Collateral or to obtain provisional or ancillary remedies from a court of competent jurisdiction before, after or during any arbitration proceeding.  The exercise of a remedy does not waive the right of any party to resort to arbitration or reference.

4

13.           Waiver of Jury Trial.  To the fullest extent permitted by Applicable Law, each Obligor waives (a) the right to trial by jury (which Agent and each Lender hereby also waives) in any proceeding or dispute of any kind relating in any way to this Amendment, any Loan Documents, Obligations or Collateral.

14.           Counterparts.  This Amendment may be executed in counterparts, each of which shall constitute an original, but all of which when taken together shall constitute a single contract.  Delivery of a signature page of any Loan Document by telecopy or electronic mail shall be effective as delivery of a manually executed counterpart of such agreement.

15.           Severability.  Wherever possible, each provision of this Amendment shall be interpreted in such manner as to be valid under Applicable Law.  If any provision is found to be invalid under Applicable Law, it shall be ineffective only to the extent of such invalidity and the remaining provisions of this Amendment shall remain in full force and effect.

16.           Entire Agreement.  Time is of the essence of the Loan Documents.  This Amendment and the Loan Agreement, as amended hereby, and the other Loan Documents constitute the entire contract among the parties relating to the subject matter hereof, and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof.
