Administrative Agent or any other Lender, and (iv) if it is a Foreign Lender,
attached hereto is any documentation required to be delivered by it pursuant to

    Section
5.           
   Miscellaneous.

     

    5.1           Reaffirmation
of Loan Documents.  Any and all of the terms and provisions of
the Credit

Documents shall, except as amended and modified hereby, remain in full force and

affirmed and extended to secure the Lender Indebtedness as they may be increased
pursuant hereto.

     

    
      5.2           Parties
in Interest.  All of the terms and provisions of this First
Amendment shall bind and inure to the benefit of the parties hereto and their
respective successors and assigns.

    

     

    
      
        
           

        

        
          6

          
            

          

        

        
           

        

      

    

     

    5.3           Legal
Expenses.  Borrower hereby agrees to pay on demand all
reasonable and substantiated out-of-pocket fees and expenses of counsel to

documents.

     

    5.4           Counterparts.  This
First Amendment may be executed in counterparts, and all parties need not
execute the same counterpart.  Facsimiles or other electronic
transmissions (e.g., pdf) shall be effective as originals.

     

    5.5           Complete

PARTIES.

     

    5.6           Headings.  The

amplify or modify the terms of this First Amendment, nor affect the meaning

    5.7           No
Waivers.  No failure or delay on the part of Administrative
Agent or Lenders to exercise any right or remedy under the Credit
Agreement,
any other Loan Documents or applicable law shall operate as a waiver thereof,
nor shall any single or partial exercise of any right or remedy preclude any
other or further exercise of any right or remedy, all of which are cumulative
and may be exercised without notice except to the extent notice is expressly
required (and has not been waived) under the Credit
Agreement,
the other Loan Documents and applicable law.

     

    5.8           Effectiveness.  This
First Amendment shall be effective automatically and without necessity of any
further action by Borrower, Administrative Agent or Lenders when counterparts
hereof have been executed by Borrower, the other Credit Parties party hereto,
Administrative Agent and Required Lenders (which shall include New Lender and
each Lender whose Commitment is increasing hereunder), and all conditions to the
effectiveness hereof set forth herein have been satisfied.

     

    IN
WITNESS WHEREOF, the parties hereto have caused this First Amendment to be duly
executed by their respective authorized officers on the date and year first
above written.
