                               - - - - - - - - - -

              WHEREAS, the Borrower, the Lenders and the Agent are parties to
the Agreement; and

              WHEREAS, the Borrower has requested that the Lenders agree to
amend certain provisions contained in the Agreement, and the Lenders and the
Agent are agreeable to such request upon the terms and subject to the conditions
set forth herein.

              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 Lenders and the Agent hereby
agree as follows:

              1.  DEFINITIONS.  All terms defined in the Agreement shall have
such defined meanings when used herein unless otherwise defined herein.

              2.  AMENDMENT OF SUBSECTION 1.1.  The definition of "U.K.
SUBSIDIARIES" in subsection 1.1 of the AGREEMENT is hereby amended by deleting
such definition in its entirety and substituting in lieu thereof the following:

           ""U.K. SUBSIDIARIES": U.K. Holdings and its Subsidiaries."

              3.  AMENDMENT OF SUBSECTION 8.4. Subsection 8.4 of the Agreement
is hereby amended by (i) deleting the word "and" appearing at the end of
clause (h) thereof and substituting in lieu thereof a COMMA, (ii) replacing
the period at the end of clause (i) thereof with the phrase ", and" and
(iii) adding at the end of such subsection the following:

                  "(j) Guarantee Obligations of the Borrower in respect of

<PAGE>

              4.  AMENDMENT OF SUBSECTION 8.8(A). Subsection 8.8(a) of the
Agreement is hereby amended by deleting from clause (ii) thereof the phrase "in
respect of any management SUBSCRIPTION or similar employment agreement".

              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 subsection 5 of
the Agreement and in the other Loan Documents are true and correct in all
material respects, PROVIDED that the references to the Agreement therein shall
be deemed to be references to this Amendment and to the Agreement as amended by

              7.  LIMITED AMENDMENT. Except as expressly amended herein, the
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 Agreement or
any other Loan Document 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
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 the preparation, negotiation and execution of this
Amendment, and the consummation of the transactions contemplated hereby,
including, without limitation, the reasonable fees and disbursements of its
