         supplemented from time to time, the NOTES and such Terms and
         Conditions of Notes, as amended, modified or supplemented from time
         to time, the TERMS AND CONDITIONS OF NOTES) pursuant to an

         among the Issuer and the Noteholders party thereto (as amended,
         modified or supplemented from time to time, the AGREEMENT OF
         UNDERSTANDING). In connection with the Notes, the Issuer will enter
         into the Fiscal Agency Agreement dated 11 February 2004 among the
         Issuer, Kredietbank S.A. Luxembourgeoise as fiscal agent and paying
         agent, and KBC Bank NV as principal paying agent (as amended,

(C)      Pursuant to Clause 2.1 of the Collateral Agency Agreement (as
         defined below), the Pledgee shall be the joint creditor (together
         with the relevant Noteholder) of each and every obligation of the
         Pledgor, as guarantor, towards each of the Noteholders under the

         between the Noteholders and the Pledgee with regard to the sums
         owed under the Notes and the other Credit Documents.

4.       COLLECTION OF RECEIVABLES AND NOTIFICATION

4.1      RECEIVABLES

(a)      As long as no Event of Default shall have occurred and is
         continuing, the Pledgor shall be free to collect all amounts due
         under the Receivables as it sees fit provided that the Pledgor
         shall not be entitled to collect any amount under any Insurance
         Receivable in excess of EUR 1,000,000.

(b)      The Pledgor shall notify, without delay and in any event no later
         than five (5) Business Days following the date hereof, the debtors
         and counterparties listed on Schedule 1-A against whom it currently
         holds Intra-Group Receivables of the fact that such Intra-Group
         Receivables owing or to be owed from them have been pledged to the
         Pledgee pursuant to this Agreement, and the Pledgor shall use its
         best efforts to deliver to the Pledgee such debtors' and
         counterparties' signed acknowledgements thereto no later than ten
         (10) Business Days following the date hereof. Each such
         notification shall be substantially in the form of Schedule 2 to
         this Agreement. With respect to each Intra-Group Receivable arising
         from debtors other than those listed in Schedule 1-A to this
         Agreement (as said Schedule 1-A may be supplemented from time to
         time pursuant to Clause 5.2 (e)) that the Pledgor acquires after
         the date hereof, the Pledgor shall notify, without delay and in any
         event no later than five (5) Business Days following the date of
         such acquisition, the debtors and counterparties against whom it
         holds such Intra-Group Receivables of the fact that such
         Intra-Group Receivables owing from them have been pledged to the
         Pledgee pursuant to this Agreement, and the Pledgor shall use its
         best efforts to deliver to the Pledgee such debtors' and
         counterparties' signed acknowledgements thereto no later than ten
         (10) Business Days following the date of such acquisition. Each
         such notification shall be substantially in the form of Schedule 2
         to this Agreement. For the avoidance of doubt, the Pledgee shall
         not have any obligation to obtain the debtors' and counterparties'
         signed acknowledgement itself.

(c)      Upon the occurrence of an Event of Default that is continuing, the
         Pledgor shall immediately notify the debtors and counter parties
         against whom it holds Trade Receivables of the fact that the Trade
         Receivables owing from them have been pledged to the Pledgee
         pursuant to this Agreement, and that such Receivables may only be
         discharged by payment to the Pledgee. Such notification shall be
         substantially in the form of Schedule 3 to this Agreement.

(d)      As long as no Event of Default shall have occurred and is
         continuing, the Pledgor shall be free to operate the Bank Accounts
         and to collect any amounts due to it with respect to the Bank
         Accounts. The Pledgor shall notify, without delay and in any event
         no later than five (5) Business Days following the date hereof, the
         Persons listed on Schedule 1-B at which it currently maintains Bank
         Accounts of the fact that such Bank Accounts have been pledged to
         the Pledgee pursuant to this Agreement, and the Pledgor shall use
         its best efforts to deliver to the Pledgee such Persons' signed
         acknowledgements thereto no later than ten (10) Business Days
         following the date hereof which shall include a waiver of set-off
         or pledge and the benefit of any 'unicity of account' or similar
         provision, except with respect to the payment of its customary fees
         and commissions in connection with ordinary course banking
         services. Each such notification shall be substantially in the form
         of Schedule 4 to this Agreement. With respect to each Person other
         than as listed in Schedule 1-B (as said Schedule 1-B may be
         supplemented from time to time pursuant to Clause 5.2 (e)) at which
         the Pledgor maintains any other Bank Account after the date hereof,
         the Pledgor shall notify, without delay and in any event no later
         than five (5) Business Days following the date it opens such Bank
         Account, such Persons of the fact that such Bank Accounts have been
         pledged to the Pledgee pursuant to this Agreement, and the Pledgor
         shall use its best efforts to deliver to the Pledgee such Persons'
         signed acknowledgements thereto no later than ten (10) Business
         Days following the date such Bank Accounts are opened which shall
         include a waiver of set-off or pledge and the

         benefit of any 'unicity of account' or similar provision, except
         with respect to the payment of its customary fees and commissions
         in connection with ordinary course banking services. Each such
         notification shall be substantially in the form of Schedule 4 to
         this Agreement. For the avoidance of doubt, the Pledgee shall not
         have any obligation to obtain the signed acknowledgement (including
         a waiver of set-off or pledge) and the benefit of any "unicity of
         account" or similar provision itself.

(e)      The Pledgor shall notify, without delay and in any event no later
         than ten (10) Business Days following the date hereof, the
         counterparties to the insurance contracts listed on Schedule 1-C of
         the fact that any Insurance Receivable owed or to be owed under
         such insurance contracts have been pledged to the Pledgee pursuant
         to this Agreement, and the Pledgor shall use its best efforts to
         deliver to the Pledgee such counterparties' signed acknowledgements
         thereto no later than twenty (20) Business Days following the date
         hereof. Each such notification shall be substantially in the form
         of Schedule 5 to this Agreement. With respect to any Insurance
         Receivables owed or to be owed under insurance contracts other than
         those listed in Schedule 1-C to this Agreement (as said Schedule
         1-C may be supplemented from time to time pursuant to Clause 5.2
         (e)) that the Pledgor enters into after the date hereof that are
         subject to Clause 3.1(f), the Pledgor shall notify, without delay
         and in any event no later than ten (10) Business Days following the
         date of such entering into such insurance contracts, the
         counterparties to such insurance contracts of the fact that such
         Insurance Receivables owing or to be owed from them have been
         pledged to the Pledgee pursuant to this Agreement, and the Pledgor
         shall use its best efforts to deliver to the Pledgee such
         counterparties' signed acknowledgements thereto no later than
         twenty (20) Business Days following the date of such entering into
         such insurance contracts. Each such notification shall be
         substantially in the form of Schedule 5 to this Agreement. For the
