          WHEREAS, the Borrower and the Parent have requested that the Lenders 
agree to amend or waive certain provisions of the Credit Agreement and the

          NOW, THEREFORE, in consideration of the premises and mutual 
agreements contained herein, and for other valuable consideration the receipt 
of which is hereby acknowledged, the Borrower, the Parent and the Agent hereby
agree as follows:

          1. Definitions.  All terms defined in the Credit

Agreement shall have such defined meanings when used herein unless otherwise
defined herein.

          2. Amendment of Subsection 1.1.  Subsection 1.1 of the Credit 
Agreement is hereby amended by deleting the word "required" in the sixth line

               Subsidiary of the parent in respect of loans made pursuant to   
               the Operator Financing Program which are sold as described in   
               clause (iii) of the definition of such term, provided that      
               such Guarantee Obligations do not, in the aggregate, exceed     
               $50 million at any one time outstanding."

relettering paragraph (h) as (i) and adding the following new paragraph (h):

                 "(h)  Guarantee Obligations relating to obligations of any 
                  kind of the Borrower, the Parent, or any of the Parent's     
                  subsidiaries that are not prohibited by this Agreement".

          4. Waivers.  The Lenders hereby waive any Default or Event of Default 
that may have arisen by the reason of the incurrence, prior to the effective 
date of this Amendment, of a Guarantee Obligation of a type covered by 
subsection 7.4(h) of the Credit Agreement, as amended hereby.

          5. Representations; No Default.  On and as of the date hereof, and 
after giving effect to this Amendment, the Borrower confirms, reaffirms and 
restates that the representations and warranties set forth in Section 4 of the

          6. Conditions to Effectiveness.  This Amendment shall become 
effective on the date on which the Agent shall have received counterparts of 
this Amendment, duly executed and delivered by a duly authorized officer of 
each of the Borrower, the Parent, each Guarantor which is a party to the 
Subsidiaries Guarantee and the Required Lenders.
                              


          7. Limited Effect.  Except as expressly amended herein, the Credit 
Agreement shall continue to be, and shall remain, in full force and effect.  
This Amendment shall not be deemed to be a waiver of, or consent to, or a 
modification or amendment of, any other term or condition of the Credit 
Agreement or to prejudice any other right or rights which the Lenders may now 
have or may have in the future under or in connection with the Credit Agreement 
or any of the instruments or agreements referred to therein, as the same may be 
amended from time to time.

          8. Costs and Expenses.  The Borrower agrees to pay or reimburse the 
Agent for all its reasonable and customary out-of-pocket costs and expenses 
incurred in connection with this Amendment, including, without limitation, the 
reasonable fees and disbursements of its counsel.

AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.
