                                                                Execution copy

2.       APPOINTMENT OF THE COLLATERAL AGENT AND RELATED MATTERS

2.1      APPOINTMENT AND DUTIES OF THE COLLATERAL AGENT; COLLATERAL AGENT AS
         JOINT CREDITOR

(a)      The Requisite Noteholders acting pursuant to the Second Noteholders
         Meeting have approved the Appointment of the Collateral Agent and,
         as a result thereof and pursuant hereto, KBC

                                     2



                                                                Execution copy

         Bank NV is hereby irrevocably appointed to act as collateral agent
         hereunder and under the Subsidiary Guaranties and the Collateral
         Documents on behalf of and for the benefit of the Noteholders with
         such powers as are expressly granted to the Collateral Agent by the
         terms of this Agreement, the Subsidiary Guaranties and the
         Collateral Documents, together with such other powers as are
         reasonably incidental thereto. The Collateral Agent hereby accepts
         such appointment, and agrees to act as Collateral Agent as set out
         herein and therein. The Credit Parties, by execution of a
         counterpart hereof, and the Collateral Agent acknowledge that the
         Collateral Agent, as joint creditor of the Obligations, acts in
         respect of the Collateral, the Subsidiary Guaranties and the
         Collateral Documents, in its own name and for its own account, and
         for the benefit of the Noteholders, as set out herein.

(b)      In furtherance but not in limitation of the foregoing, the
         Collateral Agent is authorised to:

         (i)      perform the duties and to exercise the rights, powers and
                  discretions of a secured creditor under the applicable law
                  in respect of the Subsidiary Guaranties, the Collateral
                  Documents and the Collateral, together with any other
                  incidental rights, powers and discretions;

         (ii)     execute each Subsidiary Guaranty and Collateral Document
                  expressed to be executed by the Collateral Agent; and

         (iii)    take the steps required to perfect the Collateral.

(c)      The Issuer and each Subsidiary Guarantor agree that the Collateral
         Agent shall be the joint creditor (together with the relevant
         Noteholders) of each and every obligation of the Issuer and of each
         Subsidiary Guarantor towards the Noteholders under the Notes and
         under each Subsidiary Guaranty, and the other Credit Documents to
         which the Issuer or such Subsidiary Guarantor is party, as the case
         may be. Accordingly, the Collateral Agent will have its own
         independent right to demand performance by the Issuer and each
         Subsidiary Guarantor of those obligations. However, any discharge
         of such obligations to one of the Collateral Agent or a Noteholder
         shall, to the same extent, discharge the corresponding obligation
         owing to the other. Without limiting or affecting the Collateral
         Agent's rights against the Issuer or any Subsidiary Guarantor
         (whether under this paragraph or under any provision of any
         Collateral Document), the Collateral Agent agrees for the benefit
         of each Noteholder (on a several and divided basis) that, subject
         as set out in the next sentence, it will not exercise its rights as
         a joint creditor with a Noteholder except as provided in this
         Collateral Agency Agreement. However, for the avoidance of doubt,
         nothing in the previous sentence shall in any way limit the
         Collateral Agent's right to act in the protection or preservation
         of rights under or to enforce any Subsidiary Guaranty or Collateral
         Document or other Credit Document (or to do any act reasonably
         incidental to any of the foregoing).

2.2      POSITION OF THE COLLATERAL AGENT

(a)      To the extent that it is a Noteholder, the Collateral Agent shall
         have the same rights and powers as any other Noteholder and may
         exercise such rights and powers as though it were not the
         Collateral Agent.

(b)      The Collateral Agent may:

         (i)      carry on any business with a Noteholder, the Issuer, a
                  Subsidiary Guarantor, or any of their respective
                  Affiliates; and

                                     3



                                                                Execution copy

         (ii)     retain any profits or remuneration it receives in relation
                  to any other business it carries on with a Noteholder, the
                  Issuer, a Subsidiary Guarantor, or any of their respective
                  Affiliates.

2.3      RELIANCE

         The Collateral Agent may:

(a)      rely on any notice or document believed by it in good faith to be
         genuine and correct and to have been signed by, or with the
         authority of, the proper Person or Persons;

(b)      rely on any statement made by any Person regarding any matters
         which may reasonably be assumed to be within his knowledge or
         within his power to verify;

(c)      rely on the written direction of the Requisite Noteholders or
         certifying that the Persons signing such direction constitute the
         Requisite Noteholders;

(d)      engage, pay for and rely on professional advisers selected by it;
         and

(e)      act under the Subsidiary Guaranties and the Collateral Documents
         through its personnel and agents.

2.4      REQUISITE NOTEHOLDERS' INSTRUCTIONS

(a)      The Collateral Agent shall be entitled to act and shall be fully
         protected if it acts upon the instructions of the Requisite
         Noteholders in the exercise of any right, power or discretion or
         any matter not expressly provided for in the Subsidiary Guaranties
         or the Collateral Documents. Any such instructions given by the
         Requisite Noteholders will be binding on all the Noteholders. In
         the absence of instructions from the Requisite Noteholders, the
         Collateral Agent may act as it considers to be in the best
         interests of all the Noteholders.

(b)      The Collateral Agent may assume that, unless it has received notice
         to the contrary, any right, power, authority or discretion vested
         in any Noteholder has not been exercised.

(c)      The Collateral Agent may require the receipt of security reasonably
         satisfactory to it, whether by way of payment in advance or
         otherwise, against any liability or loss which it may incur in
         complying with the instructions of the Requisite Noteholders.

(d)      Persons indirectly holding Notes through accounts held with
         intermediary institutions shall be entitled to instruct the
         Collateral Agent, shall be deemed to be a "Noteholder" for purposes
         of such instructions and the Collateral Agent shall be entitled to
         rely thereon.

2.5      APPOINTMENT OF CO-COLLATERAL AGENT

         The Collateral Agent may and, upon the request of the Requisite
         Noteholders, shall, upon the consent of the Issuer (which consent
         shall not be unreasonably withheld and shall not be required if an
         Event of Default has occurred and is continuing) and by an
         instrument in writing delivered to the Issuer, the Subsidiary
         Guarantors and each Noteholder, appoint a bank or trust company or
         an individual to act as separate Collateral Agent or co-Collateral
         Agent in a jurisdiction where the Collateral Agent is disqualified
         from acting or for any other purpose deemed by the Collateral Agent
         or the Requisite Noteholders to be advantageous to their respective
         interests, such separate Collateral Agent or co-Collateral Agent to
         exercise only such rights and to have only such duties as shall be
         specified in the instrument of appointment. The Issuer will pay the
         reasonable compensation and expenses of any such

                                     4



                                                                Execution copy

         separate Collateral Agent or co-Collateral Agent and, if requested
         by the Collateral Agent, such separate Collateral Agent or
         co-Collateral Agent or the Requisite Noteholders, the Issuer and
         the Subsidiary Guarantors will enter into an amendment to this
         Agreement, satisfactory in substance and form to the Collateral
         Agent or the Requisite Noteholders and such separate Collateral
         Agent or co-Collateral Agent, confirming the rights and duties of
         such separate Collateral Agent or co-Collateral Agent.

3.       ENFORCEMENT OF SECURITY

(a)      Subject to the terms of this Agreement and the relevant Subsidiary
         Guaranties and Collateral Documents, the Requisite Noteholders may
         give or refrain from giving instructions to the Collateral Agent to
         enforce or to refrain from enforcing or otherwise exercising its
         rights and remedies under or pursuant to the Subsidiary Guaranties,
         the Collateral Documents and the Collateral as Requisite
         Noteholders see fit.

         If so instructed by the Requisite Noteholders, the Collateral Agent
         shall enforce or otherwise exercise its rights and remedies under
         or pursuant to the Collateral Documents and the Collateral in its
         own name and for its account as a joint creditor of the relevant
         Noteholders.

(b)      Subject to the terms of this Agreement, the Collateral Agent shall
         enforce or refrain from enforcing or otherwise exercising its
         rights and remedies under or pursuant to the Subsidiary Guaranties,
         the Collateral Documents and the Collateral in such manner as the
         Requisite Noteholders shall instruct or, in the absence of such
         instructions, as it sees fit and, subject as required by applicable
         law, solely having regard to the interests of the Noteholders.

(c)      The Collateral Agent shall at all times (whether before or after
         the occurrence and continuance of an Event of Default) have the
         right and authority to direct the time, method and place of
         conducting any proceeding or the exercise of any right or remedy
         available to the Collateral Agent with respect to the Collateral or
         for taking any other action authorised by the Collateral Documents;
         provided that (i) following the occurrence and continuance of an
         Event of Default, upon delivering to the Collateral Agent a notice
         (a "NOTICE OF ENFORCEMENT") stating (a) that an Event of Default
         has occurred and is continuing, and (b) the aggregate principal
         amount of the Notes held by the Noteholders delivering such notice,
         the Requisite Noteholders shall have the right to assume such right
         and authority of the Collateral Agent and thereafter shall have the
         exclusive right and authority to direct the Collateral Agent as to
         such matters and (ii) nothing in this Section 3 shall impair the
         right of the Collateral Agent in its discretion to take any action
         deemed proper by the Collateral Agent which is not inconsistent
         with the direction by the Requisite Noteholders.

(d)      A Notice of Enforcement shall be deemed to have been given when
         such Notice of Enforcement has actually been received by the
         Collateral Agent and to have been rescinded when the Collateral
         Agent has actually received a notice of such rescindment. A Notice
         of Enforcement shall be deemed to be in effect at all times after
         such Notice of Enforcement has been given until such time, if any,
         as such Notice of Enforcement has been rescinded.

(e)      If:

         (i)      upon enforcement of any of the Collateral, the Collateral
                  Agent sells or otherwise disposes of any asset; or

         (ii)     the Issuer or any Subsidiary sells or otherwise disposes
                  of an asset either when permitted to do so under the Notes
                  or at the request of or with the consent of the Requisite
                  Noteholders upon the occurrence and continuance of an
                  Event of Default under the Notes,

                                     5



                                                                Execution copy

         the Collateral Agent is authorised to, and, at the request of the
         Issuer or the Requisite Noteholders, as applicable, shall execute
         in the name and on behalf of itself and each Noteholder, without
         the need for any further referral to or authority from such
         Noteholder, as the case may be:

         (A)      a release of the Liens on such asset; and/or

         (B)      if such asset comprises all of the Capital Stock of a
                  Subsidiary Guarantor, a release of (i) all present and
                  future liabilities (both actual and contingent) of such
                  Subsidiary Guarantor under the Notes and (ii) the Liens
                  created by the Collateral Documents with respect to any
                  Collateral of such Subsidiary Guarantor.

         provided that in each such case the proceeds are to be applied in
         the manner provided for in this Agreement and the Terms and
         Conditions of Notes.

4.       PROCEEDS OF ENFORCEMENT

4.1      APPLICATION OF PROCEEDS

         Subject to the rights of any preferential creditor(s) the net
         proceeds of enforcement of any of the Subsidiary Guaranties, the

         such event in accordance with Section 14 of the Terms and

         the Noteholders the original or a copy of any document which is
         delivered to the Collateral Agent for such purpose.

(b)      Except where a Subsidiary Guaranty or a Collateral Document
         specifically provides otherwise, the Collateral Agent shall not be
         obliged to review or check the adequacy, accuracy or completeness

         Parties.

                  Noteholder with any credit or other information concerning
                  the risks arising under or in connection with the Notes,
                  Subsidiary Guaranties or Collateral Documents (including
                  any information relating to the financial condition or
                  affairs of the Issuer or the Subsidiary Guarantors or the
                  nature or extent of recourse against any party or its
                  assets) whether coming into its possession before, on or
                  after the date of this Agreement; or

         (ii)     unless specifically requested to do so by a Noteholder or

         Collateral Agent is treated as a separate entity from its other
         divisions and departments. Any information acquired by the
         Collateral Agent which, in its opinion, is acquired by it other
         than in its capacity as the Collateral Agent may be treated as

         information possessed by the Collateral Agent in its capacity as
         such.

         employees and agents to maintain confidential) any confidential
         information that it may receive from any Credit Party in its

         accordance with its established practices for keeping information
         confidential (which shall be in compliance with laws applicable to
         it) and, prior to the occurrence and continuance of an Event of
         Default, shall not disclose such information to third parties

         professional advisors to the Collateral Agent; (b) to regulatory
         officials having jurisdiction over the Collateral Agent; (c) as
         required by applicable law or in connection with any legal
         proceeding after prior notification to the Issuer; (d) to any

         advisors, provided that such Noteholder shall have agreed in
         writing to keep such information confidential in the same manner as
         the Collateral Agent has agreed pursuant to this paragraph; (e) to
         account debtors and other persons as expressly required or
         permitted pursuant to the Credit Documents; and (f) of information
         that has been previously disclosed publicly without breach of this
         provision; provided that this paragraph shall not apply after the
         occurrence and during the continuance of any Event of Default.

5.5      COMPLIANCE

         The Collateral Agent may refrain from taking any action (including

         its opinion, is reasonable necessary or desirable to comply with
         any law or regulation.

         and Subsidiary Guarantors as may be in possession of the Collateral
         Agent and has not theretofore been disposed of, applied or

6.       EXPENSES AND INDEMNITIES

(a)      The Issuer agrees to indemnify and hold harmless the Collateral
         Agent and its directors, officers, employees, agents and advisors
         from and against any and all claims, losses, liabilities,
         obligations, damages and expenses (including reasonable fees and
         expenses of counsel) that may be incurred by or asserted or awarded
         against the Collateral Agent or any such Person (hereinafter the
         "INDEMNIFICATION AMOUNT") arising out of, related to or in
         connection with (i) this Agreement or any Subsidiary Guaranty or
         Collateral Document (including the enforcement of any Subsidiary
         Guaranty or Collateral Document) or (ii) any refund or adjustment
         of any amount paid or payable to the Collateral Agent under or in
         respect of any Subsidiary Guaranty or Collateral Document or any
         Collateral, or any interest thereon, which may be ordered or
         otherwise required by any Person, except to the extent such claims,
         losses, liabilities, damages and expenses are found by a court of
         competent jurisdiction to have resulted from such Person's gross
         negligence or wilful misconduct. If the Issuer fails to pay on
         demand the Indemnification Amount, interest will accrue thereon at
         a rate per annum equal to that specified in Section 1 of the Terms
         and Conditions of Notes from the scheduled date for payment thereof
         until the actual date of payment and such interest shall be added
         to the Indemnification Amount.

         amount of any and all reasonable out-of-pocket expenses, including

         may incur in connection with (i) the administration of this
         Agreement and the other Subsidiary Guaranties and Collateral
         Documents including all filings, fees and other matters relating to
         or in connection with the perfection of Liens in the Collateral,
         (ii) the custody or preservation of, or the sale of, collection
         from, or other realisation upon, any of the Collateral, (iii) the
         exercise or enforcement (whether through negotiations, legal
         proceedings or otherwise) of any of the rights or remedies of the
         Collateral Agent under the Subsidiary Guaranties or the Collateral
         Documents or (iv) the failure by any Credit Party or any other
         Person (other than the Collateral Agent) to perform or observe any
         of the provisions of the Subsidiary Guaranties, Collateral
         Documents or any other Credit Document. The Issuer hereby agrees to
         pay to the Collateral Agent, for its own account, an annual fee in
         an amount agreed upon by the Issuer and the Collateral Agent from
         time to time, which shall be payable by the Issuer annually in

         of this Agreement and all other Credit Documents.

7.       RESIGNATION OF THE COLLATERAL AGENT

(a)      The Collateral Agent may resign and appoint any of its affiliates
         as successor Collateral Agent by giving 30 days' prior written
         notice to the Issuer and the Requisite Noteholders.

(b)      Alternatively, the Collateral Agent may resign by giving 30 days'
         prior written notice to the Issuer, the Subsidiary Guarantors and
         the Noteholders, in which case the Requisite Noteholders may
         appoint a successor Collateral Agent; provided that, if an Event of
         Default has not occurred and is continuing, such successor shall be
         reasonably acceptable to the Issuer.

(c)      If no successor Collateral Agent has been appointed under paragraph
         (b) above within 60 days after notice of resignation was given, the
         Collateral Agent may appoint a successor Collateral Agent who is
         reasonably acceptable to the Requisite Noteholders and the Issuer.

         banking business in the European Community that is eligible to act
         in the capacity as Collateral Agent.

         successor Collateral Agent shall become effective upon notification
         of the successor Collateral Agent to the Issuer, the Subsidiary
         Guarantors and the Noteholders that it accepts its appointment.
         Upon receipt of such notification, the successor Collateral Agent
         will succeed to the position of the Collateral Agent and the term
         "COLLATERAL AGENT" will mean the successor Collateral Agent.

(f)      The retiring Collateral Agent shall, at the Issuer's cost and
         expense, make available to the successor Collateral Agent such
         documents and records and provide such assistance as the successor
         Collateral Agent may reasonably request for the purposes of
         performing its functions as the Collateral Agent under this
         Agreement, the Subsidiary Guaranties and the Collateral Documents.

(g)      Upon its resignation becoming effective, this Clause shall continue
         to benefit the retiring Collateral Agent in respect of any action
         taken or not taken by it in connection with this Agreement, the
         Subsidiary Guaranties or the Collateral Documents while it was the
         Collateral Agent, and, subject to paragraph (f) above, it will have
         no further obligations under any Subsidiary Guaranty or Collateral
         Document.

(h)      The Requisite Noteholders may, by notice to the Collateral Agent,
         require the Collateral Agent to resign under paragraph (b) above.

(i)      Notwithstanding the foregoing, the appointment of a successor
         Collateral Agent shall not be effective unless and until all
         actions have been taken to ensure that all Liens (including the
         perfection thereof) under the Collateral Documents will be
         maintained after giving effect to the appointment of such successor
         Collateral Agent. Both the retiring and successor Collateral Agent
         shall use commercially reasonable efforts to minimise any fees and
         expenses in connection with this clause (i).

         (b)      Any amendment to Section 6 of this Agreement or this
                  Section 9.2 must be in writing and acknowledged and agreed
                  to by the Issuer.

9.3      NO WAIVER

         No failure or delay by the Collateral Agent or the Noteholders in
         exercising any right, power or remedy under this Agreement shall
         operate as a waiver thereof nor shall any single or partial
         exercise or waiver of any right, power or remedy. The remedies
         provided in this Agreement are cumulative and are not exclusive of
         any remedies provided by law. Unless otherwise specified in such
         waiver or consent, a waiver or consent given hereunder shall be
         effective only in the specific instance and for the specific
         purpose for which given.

9.4      SEVERABILITY

         Each of the provisions of this Agreement is several and distinct
         from the others and if at any time one or more of such provisions
         is or becomes invalid illegal or unenforceable the validity,
         legality and enforceability of the remaining provisions hereof
         shall not in any way be affected or impaired thereby.

         In case of any such illegality, invalidity or unenforceability, the
         parties shall negotiate in good faith with a view to agree on the
         replacement of such provision by a provision which is legal, valid
         and enforceable and which is to the extent practicable in
         accordance with the intents and purposes of this Agreement and
         which in its economic effect comes as close as practicable to the
         provision being replaced.

                                                                Execution copy
