ARTICLE IV

MISCELLANEOUS

Section 4.1.                                Amendments; Interpretation.  No amendment or modification of any provision of this Amendment shall be effective without the written agreement of each Loan Party, the Administrative Agent and the Required Lenders, and no waiver of any provision of this Amendment, or consent to any departure by any Loan Party therefrom, shall in any event be effective without the written concurrence of the Required Lenders.  Any waiver or consent shall be effective only in the specific instance and for the specific purpose for which it was given.  No notice to or demand upon any Loan Party in any case shall entitle any Loan Party to any other or further notice or demand in similar or other circumstances.  No prior drafts of this Amendment, or any negotiations regarding the terms contained in those drafts, shall be admissible in any court to vary or interpret the terms of this Amendment, the parties hereto agreeing that this Amendment constitutes the final expression of the parties’ agreement and supersedes all prior written and oral understandings regarding the terms of this Amendment.  The parties hereto have had the opportunity to be represented by counsel in their negotiations of the terms of this Amendment, and therefore no provision of this Amendment shall be construed against any party hereto on the theory that such party drafted such provision.

Section 4.2.                                No Waiver.  The Administrative Agent’s or any Lender’s failure, at any time or times, to require strict performance by any Loan Party of any provision or term of this Amendment or of any of the Credit Documents shall not waive, affect or diminish any right of the Administrative Agent or the Lenders thereafter to demand strict compliance and performance therewith.  Any suspension or waiver by the Administrative Agent or the Lenders of a Forbearance Default shall not suspend, waive or affect any other Forbearance Default or any Event of Default, whether the same is prior or subsequent thereto and whether of the same or of a different kind or character.  Without limiting the generality of the foregoing, nothing herein

6

constitutes a waiver of any Event of Default (whether or not such Event of Default constitutes a Designated Event of Default).

Section 4.3.                                Submission to Jurisdiction.  The Administrative Agent, the Lenders and each Loan Party each agree that all disputes among them arising out of, connected with, related to, or incidental to the relationship established between them in this Amendment, and whether arising in contract, tort, equity, or otherwise, shall be resolved only by the courts of the State of New York sitting in the Borough of Manhattan in the City of New York or the United States District Court for the Southern District of New York, and appellate court from any thereof.  The Administrative Agent, the Lenders and each Loan Party each waives in all disputes any objection that any of them may have to the location of the court considering the dispute which court shall have been chosen in accordance with the foregoing.

Section 4.4.                                WAIVER OF JURY TRIAL.  EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE, BETWEEN THE ADMINISTRATIVE AGENT AND THE LENDERS AND ANY LOAN PARTY OR ANY OF THEIR RESPECTIVE AFFILIATES ARISING OUT OF, CONNECTED WITH, RELATED TO OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN THIS AMENDMENT.  INSTEAD, ANY DISPUTES RESOLVED IN COURT WILL BE RESOLVED IN A BENCH TRIAL WITHOUT A JURY.

Section 4.5.                                Section Titles.  The section and subsection titles contained in this Amendment are included for the sake of convenience only, shall be without substantive meaning or content of any kind whatsoever, and are not a part of the agreement between each Loan Party, the Administrative Agent and the Lenders.  Any reference in this Amendment to any “Section” refers, unless the context otherwise indicates, to a section of this Amendment.

Section 4.6.                                CHOICE OF LAW.  EACH OF THE LENDERS, THE ADMINISTRATIVE AGENT AND EACH LOAN PARTY HEREBY AGREES THAT ALL DISPUTES AMONG OR BETWEEN THEM, ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO, THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN THIS AMENDMENT, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY, OTHERWISE, SHALL BE RESOLVED IN ACCORDANCE WITH THE INTERNAL LAWS (AND NOT THE CONFLICTS OF LAW PROVISIONS) OF THE STATE OF NEW YORK.

Section 4.7.                                Notices.  All notices, requests and demands to or upon the respective parties hereto shall be given in accordance with the Credit Agreement.

Section 4.8.                                Counterparts.  This Amendment may be executed in any number of separate counterparts (which may include counterparts delivered by facsimile or electronic mail), each of which shall be deemed an original but all of which together shall constitute one and the same instrument.
