         later than twenty (20) Business Days following the date of entering
         into such insurance contracts. Each such notification shall be

         avoidance of doubt, the Assignee shall not have any obligation to
         obtain the counterparties' signed acknowledgements itself.

(d)      The Assignor shall provide the Assignee without delay with a copy
         of any notification given pursuant to this Clause 7, together with
         the adequate evidence of such notification having been sent and
         received. For the avoidance of doubt, the Assignee shall not have
         any obligations to investigate or verify whether the Assignor has
         complied with any of its notification obligations.

(e)      The Assignee may give any notice required to be given pursuant to
         this Clause 7 if the Assignor has not given such notice within five
         (5) Business Days after the Assignor is required or at any time
         following the occurrence and during the continuance of a Payment
         Default. For this purpose, the Assignor will deliver to the
         Assignee simultaneously with the execution of this Agreement,

         perfection measures contemplated in Clause 6 and this Clause 7

8.       ENFORCEMENT AND COLLECTION

(a)      If a Payment Default occurs and is continuing, the Assignee is
         entitled, without regard to the procedures and formalities provided
         for in the Swiss Federal Act Debt Collection and Bankruptcy of
         1889, as amended:

         (i)   to immediately realise any and all of the Claims to the extent
               necessary to satisfy any outstanding Secured Obligations by
               collecting all or part of the Claims;

         (ii)  to revoke, with immediate effect, the Assignor's authorisation
               to dispose of the Account Balances vis-a-vis the Banks; and

         (iii) to realize, at its discretion, all or part of the Account
               Balances (including, for the avoidance of doubt, any new
               payments of Trade Receivables made to the Bank Accounts
               subsequent to the revocation mentioned above).

(b)      To the extent the Assignee is entitled to collect the Claims, it
         may request upon the written instructions of the Requisite
         Noteholders that all documents relating to the Claims be handed
         over to the Assignee and the Assignor hereby agrees to comply
         promptly with any such request. If a Payment Default is not
         continuing, the Assignee's right to collect the Claims shall cease
         and the Assignee shall pay over to the Assignor all moneys received
         in connection with such collection and retained by it during the
         continuance of the Payment Default (such

         payments being inclusive of daily interest) save to the extent any
         such moneys have been applied in payment of any of the Secured
         Obligations.

(c)      If and to the extent the Assignee collects any Claims pursuant to
         this Clause 8 (Enforcement and Collection) hereof, it may take all
         measures and enter into all agreements with such Debtors which it
         considers to be expedient. In particular, the Assignee may grant
         discounts or indulgence to Debtors and/or enter into settlement
         agreements.

9.       RIGHT OF INSPECTION

         The Assignor shall allow the Assignee to inspect at any time during
         normal business hours its records, or to have them inspected by a
         duly authorised representative, for the purpose of evaluating and
         enforcing the Claims. However, as long as no right of realisation
         exists a right of inspection for the purpose of inspecting and
         checking the Claims only shall only be upon reasonable advance
         notification and during normal business hours.

10.      BOOKKEEPING AND DATA-PROCESSING

(a)      If the Claims have been stored in an electronic data-processing
         system, the Assignor shall allow the Assignee access to the
         computer, including the peripheral equipment and all data
         concerning the Claims. Moreover, software operators shall be made
         available insofar as required, and any assistance required shall be
         provided to the Assignee. If a third party handles the electronic
         processing of data, the Assignor hereby authorises the Assignee to
         obtain these services, and instructs such third party to handle the
         processing of data for the Assignee upon its instructions as it did
         for the Assignor.

(b)      If, and to the extent, documents required for the inspecting,
         checking, evaluation or realisation of the assigned Claims have
         been delivered by the Assignor to a third party (especially to an
         accountant or tax advisor) the Assignor hereby assigns to the
         Assignee its claims against such third party for providing
         information and for delivering such documents and hereby instructs
         the third party to provide the Assignee with such information and
         documents required to inspect, check, evaluate and realise the
         assigned Claims. In so far as an electronic data processing is
         executed by third parties the Assignor hereby assigns to the
         Assignee all its claims for performance and instructs these third
         parties to execute the electronic data processing on behalf of the
         Assignee in the same manner as they were obliged towards the
         Assignor, provided that the Assignee requests them to do so. The
         Assignee hereby accepts the aforementioned assignments.

11.      UNDERTAKINGS

         The Assignor undertakes:

         (a)  not to take any steps, including without limitation to the
              exercise of any right it has under any agreement under which
              the Claims arise, which may jeopardise or materially adversely
              affect the security interest constituted in this Agreement.

         (b)  to provide the Assignee promptly at its reasonable request all
              information and documents which are necessary to asserting the
              Claims.

         (c)  to procure, to the extent possible under Swiss law, that no
              executory seizure is made on the Claims, and that any
              conservatory seizure thereon is lifted within sixty (60) days
              of it first being made; and to inform the Assignee promptly of
              any attachments (Pfandungen, Arrest) regarding any and all of
              the Claims or any other measures

                                     8

              which may impair or jeopardise the Assignee's rights relating
              to the Claims. In the event of an attachment, the Assignor
              undertakes to forward to the Assignee without undue delay a
              copy of the attachment order (Pfandungsurkunde, Arrestbefehl)
              and all other documents necessary for a defence against the
              attachment or its realisation. The Assignor shall inform the
              attaching creditor promptly about the Assignee's security
              interests;

         (d)  to notify the Assignee promptly of any event or circumstance
              which might materially adversely affect the validity or
              enforceability of this Agreement;

         (e)  to promptly execute such further instruments and documents and
              do such other acts as are necessary in order to fully effect
              the purposes of this Agreement as the Assignee may from time
              to time reasonably request upon written instructions from the
              Requisite Noteholders;

         (f)  not to assign or sell any of the Claims to any third party
              without the Assignee's prior written consent, except as
              permitted under the Credit Documents;

         (g)  not to enter into any kind of arrangement that would provide
              for the non-assignability of any assigned Claims or subject
              the assignability to the consent of a party other than the
              Assignee, without the prior written consent of the Assignee;

         (h)  not to dispose of the amounts standing to the credit of any
              Bank Account other than in the ordinary course of business or
              where such a disposal is required by law or approved by the
              Assignee in advance in writing; and

         (i)  in relation to the conduct of its business, to exclusively use
              the Bank Accounts, and, in particular, (i) to generally use
              its best endeavours to ensure that all Debtors and other
              persons make payments in relation to Claims to the Bank
              Accounts, and (ii) promptly forward any Trade Receivables that
              have been paid otherwise than into the Bank Accounts to the
              Bank Accounts.

         (j)  Without delay and in any event no later than five (5) Business
              Days following the date of acquisition of an Intra-Group
              Receivable arising from a debtor or counterparty that is not
              listed on Schedule 1-A (as supplemented from time to time),
              the Assignor shall deliver a written notice to the Assignee,
              setting forth the name and address of such additional debtor
              or counterparty (it being understood that such written notice
              shall be deemed to supplement Schedule 1-A annexed hereto for
              all purposes of this Agreement); and without delay and in any
              event no later than five (5) Business Days following the date

         Without prejudice and in addition to the representations and
         warranties of the Assignor under the Collateral Agency Agreement,

              Assignor. No resolutions have been taken, nor has any petition
              been filed, to dissolve or liquidate the Assignor, nor has the

              Accounts have been assigned to any Person other than the
              Assignee;

         (e)  all Claims can be transferred and assigned under the laws and

              ------------
              the provisions of Clause 11(j), contains a true, accurate and
              complete list of the names and addresses of all the Persons

              applicable to the Assignor as of the date hereof, its
              constitutional documents or any material contractual or other
              obligation binding upon it, that would prevent it from

         The Assignee shall not be liable for any loss or damage suffered by
         the Assignor save in respect of such loss or damage which is
         suffered as a result of the gross negligence or wilful misconduct
         of the Assignee. The Assignee shall not be under any obligation to
         the Assignor to take any steps necessary to preserve any rights in
         the Claims against any other parties but may do so at its option,
         and all expenses reasonably incurred in connection therewith shall
         be for the account of the Assignor and shall be part of the Secured

         Obligations.

         contained herein and caused by any breach of the Assignor of any of
         its obligations or undertakings contained herein other than to the
         extent that such losses, actions, claims, expenses, demands and
         liabilities are incurred or made against the Assignee as a result
         of the gross negligence or wilful misconduct of any Assignee.

14.      DURATION AND INDEPENDENCE

         This Agreement shall remain in full force and effect until the
         earlier of (a) the date upon which all Secured Obligations have
         been irrevocably paid and discharged in full; and (b) the date
         notified by the Assignee to the Issuer. This Agreement shall not
         cease to exist if any payments made in satisfaction of the Secured
         Obligations have only temporarily discharged the Secured
         Obligations.

14.2     CONTINUING SECURITY

(a)      This Agreement shall create a continuing security and no change or
         amendment or increase whatsoever to the Notes or in any document or
         agreement related thereto nor shall any release of Security affect
         the validity or the scope of this Agreement. This Agreement shall
         not be discharged or in any way prejudiced or affected by any
         change in the constitution or status of the Assignor or any other
         Person or by any legal limitation, disability, incapacity or other
         circumstances relating to the Assignor or any other Person, by any
         invalidity, illegality or unenforceability of the obligations of
         the Assignor or any other Person. The Assignee or, as the case may
         be, Requisite Noteholders may at any time without discharging or in
         any way affecting this Agreement (a) grant the Issuer or any
         Subsidiary Guarantor any time or indulgence, (b) concur in any
         moratorium of the Secured Obligations, (c) abstain from taking or
         perfecting any other security and discharge any other security, (d)
         abstain from exercising any right or recourse or from proving or
         claiming any debt and waive any right or recourse, (e) amend the
         terms and conditions of the Secured Obligations in accordance with
         the Terms and Conditions of Notes and applicable law, and (f) apply
         any payment received from the Assignor or for its account towards
         the Secured Obligations or any other obligations of the Assignor of
         the Assignee's choice.

         Assignor and the Assignee agree that in the event of a transfer of
         all or any part of the Secured Obligations by way of assignment or
         novation in accordance with the Credit Documents or in the event of
         a change or replacement of the Assignee or the Assignor in
         accordance with the Credit Documents, the Assignments will be
         maintained, automatically and without any further formality or
         consent, to secure the Secured Obligations as assigned or novated
         in favour of the Assignee (or a new assignee, if any). To the
         extent that any such further formality or consent on the part of
         Assignor will, nevertheless, be required, the Assignor hereby
         undertakes to perform any such formality or consent without delay
         upon the Assignee request.

14.3     INDEPENDENCE

         This Agreement is independent from any other Security. No other
         such Security shall prejudice, be prejudiced by, or be merged in
         any way with, this Agreement. If there is a conflict between this
         Agreement and the Terms and Conditions of Notes then (to the extent
         permitted by law) the Terms and Conditions of Notes shall take
         priority over the provisions of this Agreement.

15.      COSTS AND EXPENSES

         The Assignor will pay to the Assignee the amount of all costs,
         charges, fees and expenses (including fees for legal advisers)

         preparation, execution, performance, enforcement and amendment of
         this Agreement, or any waiver in relation thereto, together in each
         case with any applicable value added tax or other taxes.

         Changes to and amendments of this Agreement including this Clause
         16.1 (Amendments) must be made in writing. No oral supplements to
         this Agreement have been or will be made.

16.2     WAIVERS AND REMEDIES CUMULATIVE

         The rights of each Party under this Agreement:

         (a)  may be exercised as often as necessary;

         (b)  are cumulative and not exclusive of its rights or remedies
              provided by law;

         (c)  may be waived only in writing and specifically.

         No failure or delay by a party in exercising any right, power or
         privilege under this Agreement shall operate as a waiver thereof,
         nor shall any single or partial exercise of any right, power or
         privilege preclude any other or further exercise thereof or the
         exercise of any other right, power or privilege.

         All the rights of the Assignee hereunder shall be in addition to
         any other right vested in the Assignee and all such rights may be
         exercised from time to time and as often as the Assignee may deem
         expedient. The Assignor waives any right it may have of first
         requiring the Assignee to proceed against or claim payment from any
         other party, or enforce any guarantee or security before enforcing
         the Assignment.

17.      SEVERABILITY

         If any of the provisions of this Agreement should be or become
         invalid, unenforceable or impractical in whole or in part, the
         validity of the other provisions hereof shall not be affected. In
         that case the invalid, unenforceable or impractical provision is
         deemed to be replaced by such valid and enforceable provision or
         arrangement, which corresponds as closely as possible to the
         invalid, unenforceable or impractical provision and to the Parties'
         economic aims pursued by and reflected in this Agreement. The same
         applies in the event that this Agreement does not contain a
         provision which it needs to contain in order to achieve the
         economic purpose as expressed herein (Regelungslucke).

18.      RELEASE OF SECURITY

         After the full and complete satisfaction of all Secured Obligations
         or if so required by Swiss mandatory law, the Assignee shall
         reassign to the Assignor the Claims and surrender the excess
         proceeds, if any, resulting from any realisation of the Claims. The
         Assignee will, however, transfer any claims to a third party to the
         extent it is obliged to do so.

         Any release or discharge shall be null and void and without effect
         if any payment received by the Assignee and applied towards
         satisfaction of all or part of the Secured Obligations

         (a)  is avoided or declared invalid as against the creditors of the
              maker of such payment; or

         (b)  becomes repayable by the Assignee to a third party; or

         (c)  proves not to have been effectively received by the Assignee;

         and the Assignee shall be entitled to enforce this Agreement as if
         such release or discharge had not occurred.
