Page 3

Documents and any Swap Agreements executed by and between any Borrower and any Bank constitute the sole agreement of the parties with respect to the subject matter hereof and thereof and supersede all oral negotiations and prior writings with respect to the subject matter hereof and thereof.

However, in the event of any inconsistencies among this Loan Agreement, as modified hereby, and any of the Loan Documents, the terms of the Loan Agreement shall control.

7. ARBITRATION. Upon demand of any party hereto, whether made before or after institution of any judicial proceeding, any dispute, claim or controversy arising out of, connected with or relating to the Loan Agreement or any other Loan Document (“Disputes”) between or among the Borrower, the Agent and the Banks, or any of them, shall be resolved by binding arbitration as provided herein. Institution of a judicial proceeding by a party does not waive the right of that party to demand arbitration hereunder. Disputes may include, without limitation, tort claims, counterclaims, claims brought as class actions, claims arising from documents executed in the future, or claims arising out of or connected with the transactions contemplated by the Loan Agreement and the other Loan Documents. Arbitration shall be conducted under and governed by the Commercial Financial Disputes Arbitration Rules (the “Arbitration Rules” of the American Arbitration Association (the “AAA”), as in effect from time to time, and Title 9 of the U.S. Code, as amended. All arbitration hearings shall be conducted in Philadelphia, Pennsylvania. The expedited procedures set forth in the Arbitration Rules shall be applicable to claims of less than $1,000,000. All applicable statutes of limitation shall apply to any Dispute. A judgment upon the award may be entered in any court having jurisdiction. The panel from which all arbitrators are selected shall be comprised of licensed attorneys. The single arbitrator selected for expedited procedure shall be a retired judge from the highest court of general jurisdiction, state or federal, of the state where the hearing will be conducted. Notwithstanding the foregoing, this arbitration provision does not apply to Disputes under or related to Swap Agreements or Disputes to which the Borrower is not a party. Notwithstanding the preceding binding arbitration provisions, the parties hereto agree to preserve, without diminution, certain remedies that any party hereto may employ or exercise freely, either alone, in conjunction with or during a Dispute. Any party hereto shall have the right to proceed in any court of proper jurisdiction or by self-help to exercise or prosecute the following remedies, as applicable: (1) all rights of self-help, including peaceful occupation of real property and collection of rents, set-off, and peaceful possession of personal property; (2) obtaining provisional or ancillary remedies, including injunctive relief, sequestration, garnishment, attachment, appointment of a receiver and filing an involuntary bankruptcy proceeding; and (3) when applicable, a judgment by confession of judgment. Preservation of these remedies does not limit the power of an arbitrator to grant similar remedies that may be requested by a party in a Dispute. The parties hereto agree that no party shall have a remedy of punitive or exemplary damages against any other party in any Dispute, and each party hereby waives any right or claim to punitive or exemplary damages that it has now or that may arise in the future in connection with any Dispute, whether such Dispute is resolved by arbitration or judicially. Waiver of Jury Trial. THE PARTIES ACKNOWLEDGE THAT BY AGREEING TO BINDING ARBITRATION THEY HAVE IRREVOCABLY WAIVED ANY RIGHT THEY MAY HAVE TO JURY TRIAL WITH REGARD ANY RIGHT OR CLAIM TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT, OR OTHERWISE) IN ANY WAY ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY LOAN DOCUMENT.
