     Borrowers' obligations under the Documents or in respect of the Cash
     Management Obligations.

3.2  Neither the obligations of the Guarantor herein contained nor the rights,

     of the Cash Management Obligations or by law shall be discharged, impaired
     or otherwise affected by:

     (i)       the winding-up, dissolution, administration or reorganisation of
               any of the Borrowers or any change in their status, function,
               control or ownership;

     (ii)      any of the obligations of any of the Borrowers under the
               Documents or in respect of the Cash Management Obligations or

               respect;

     (iii)     time or other indulgence being granted or agreed to be granted to
               any of the Borrowers in respect of their obligations under the
               Documents or in respect of the Cash Management Obligations or
               under any other security;

     (iv)      any amendment to, or any variation, waiver or release of any

               by the Documents or in respect of the Cash Management Obligations
               or otherwise agreed to be taken in respect of any of the
               Borrowers' obligations under the Documents or in respect of the
               Cash Management Obligations;

     (vi)      any failure to realise or fully to realise the value of, or any
               release, discharge, exchange or substitution of, any security
               taken in respect of any of the Borrowers' obligations under the
               Documents or in respect of the Cash Management Obligations; or

     (vii)     any other act, event or omission which, but for this Clause 3.2,
               might operate to discharge, impair or otherwise affect any of the
               obligations of the Guarantor herein contained or any of the
               rights, powers or remedies conferred upon the


               Administrative Agent or any of the Obligees by the Documents
               or in respect of the Cash Management Obligations or by law.

3.3  Any settlement or discharge given by the Administrative Agent and/or any of
     the Obligees to the Guarantor in respect of the Guarantor's obligations
     hereunder or any other agreement reached between the Administrative Agent
     and/or any of the Obligees and the Guarantor in relation thereto shall be,
     and be deemed always to have been, void if any act on the faith of which
     the Administrative Agent and/or any of the Obligees gave the Guarantor that
     settlement or discharge or entered into that agreement is subsequently
     avoided by or in pursuance of any provision of law.

3.4  The Administrative Agent and/or any of the Obligees shall not be obliged
     before exercising any of the rights, powers or remedies conferred upon it
     in respect of the Guarantor hereby or by law:

     (i)       to make any demand of any of the Borrowers;

     (ii)      to take any action or obtain judgment in any court against any
               Borrower;

     (iii)     to make or file any claim or proof in a winding-up or dissolution
               of any Borrower; or

     (iv)      to enforce or seek to enforce any security taken in respect of
               any of the obligations of any of the Borrowers under the
               Documents or in respect of the Cash Management Obligations.

3.5  The Guarantor agrees that, so long as any amounts are or may be owed by any
     Borrower under the Documents or in respect of the Cash Management
     Obligations or any Borrower is under any actual or contingent obligations
     under the Documents or in respect of the Cash Management Obligations, the
     Guarantor shall not exercise any rights which the Guarantor may at any time
     have by reason of performance by it of its obligations hereunder:

     (i)       to be indemnified by any of the Borrowers;

     (ii)      to claim any contribution from any other guarantor of any of the
               Borrowers' obligations under the Documents or in respect of the
               Cash Management Obligations; and/or

     (iii)     to take the benefit (in whole or in part and whether by way of
               subrogation or otherwise) of any rights of the Administrative
               Agent and/or the Obligees under the Documents or in respect of
               the Cash Management Obligations or of any other security taken
               pursuant to, or in connection with, the Documents or in respect
               of the Cash Management Obligations by the Administrative Agent
               and/or the Obligees.

4.   REPRESENTATIONS AND WARRANTIES

     The Guarantor represents and warrants to each of the Obligees that the
     representations and warranties set forth in Article VIII of the Credit
     Agreement as they relate to the Guarantor or to the Documents to which the
     Guarantor is a party or in respect of the


     Cash Management Obligations, each of which is hereby incorporated herein by
     reference, are true and correct, and the Administrative Agent and each
     Obligee shall be entitled to rely on each of them as if they were fully set
     forth herein provided that each reference in each such representation and
     warranty to the Company's knowledge shall, for the purposes of this Clause
     4, be deemed to be a reference to the Guarantor's knowledge.

5.   PAYMENTS

     The provisions of the Credit Agreement relating to the payments to be made
     thereunder (including, without limitation, those regulating what is to
     happen if the Borrowers are required by law to make a deduction or
     withholding from any such payment) shall apply mutatis mutandis to payments
     to be made hereunder.

6.   CURRENCY OF ACCOUNT

     Moneys received or recovered by the Administrative Agent from the Guarantor
     in a currency other than that in which the said sums are due and payable
     under or pursuant to the Documents or in respect of the Cash Management
     Obligations or under Clause 2 hereof shall be converted into the latter
     currency at the spot rate for purchasing Dollars with such moneys as set
     forth in The Wall Street Journal on the business day prior to the date on
     which such calculation is made.

7.   CONTINUING SECURITY

     The obligations of the Guarantor herein contained shall constitute and be
     continuing obligations notwithstanding any settlement of account or other
     matter or thing whatsoever, and in particular but without limitation, shall
     not be considered satisfied by any intermediate payment or satisfaction of
     all or any of the obligations of any of the Borrowers under the Documents
     or in respect of the Cash Management Obligations and shall continue in full
     force and effect until final payment in full of all amounts owing by the
     Borrowers thereunder and total satisfaction of all the Borrowers' actual
     and contingent obligations thereunder.

8.   SET-OFF

     Upon the occurrence and during the continuation of any Event of Default,
     the Guarantor hereby irrevocably authorises each Obligee at any time and
     from time to time without notice to the Guarantor, any such notice being
     expressly waived by the Guarantor, to set-off and appropriate and apply any
     and all deposits (general or special, time or demand, provisional or
     final), in any currency, and any other credits, indebtedness or claims, in
     any currency, in each case whether direct or indirect, absolute or
     contingent, matured or unmatured, at any time held or owing by such Obligee
     to or for the credit or the account of the Guarantor, or any part thereof
     in such amounts as such Obligee may elect, against and on account of the
     obligations and liabilities of the Guarantor to such Obligee hereunder
     which are then due and payable and claims of every nature and description
     of such Obligee against the Guarantor, in any currency, whether arising
     hereunder, under any of the Documents or in respect of the Cash Management
     Obligations or otherwise in connection therewith, as such Obligee may
     elect, whether or not the Administrative Agent or any Obligee has made any
     demand for payment and although such obligations,


     liabilities and claims may be contingent or unmatured. The Administrative
     Agent and each Obligee shall notify the Guarantor promptly of any such set-
     off and the application made by the Administrative Agent or such Obligee
     provided that the failure to give such notice shall not affect the validity
     of such set-off and application. The rights of the Administrative Agent and
     each Obligee under this Clause are in addition to other rights and remedies
     (including, without limitation, other rights of set-off) which the
     Administrative Agent or such Obligee may have.

     herein.
