                  commerce) or similar foreign law security exists over the
                  business of the Company or the Pledgor, nor any mandate
                  with a view to the creation thereof, except for the

         the board of directors (goedkeuringsclausule/clause d'agrement) as
         presently set forth in said article 9 of the articles of
         association do not apply to an enforcement of the pledge under this

         Event of Default has occurred which is continuing in connection
         with the Secured Obligations, any cash return on the Shares, and,

         from any such operation shall be part of the Shares, and, as the
         case may be, the Future Shares.

6.       CONTINUING SECURITY AND OTHER MATTERS

6.1      CONTINUING SECURITY

(a)      This Pledge shall be a continuing security for the due performance
         of the Secured Obligations, and shall remain in force until
         expressly released in accordance with Clause 9 of this Agreement.

(b)      This pledge shall not be discharged by the entry of any Secured
         Obligations into any current account, in which case this Pledge
         shall secure any provisional or final balance of such current
         account up to the amount in which the Secured Obligations were
         entered therein.

(c)      This Pledge shall not be discharged or in any way prejudiced or
         affected by any change in the constitution or status of the Pledgor
         or any other Person or by any legal limitation, disability,
         incapacity or other circumstances relating to the Pledgor or any
         other Person, by any invalidity, illegality or unenforceability of
         the obligations of the Pledgor or any other Person.

(d)      The Pledgee or, as the case may be, Requisite Noteholders may at
         any time without discharging or in any way affecting this Pledge

         other right vested in the Pledgee and all such rights may be

         expedient. The Pledgor waives any right it may have of first

         secure the Secured Obligations as novated and in favour of the
         Pledgee or a new pledgee.

         Notes, to:

                                     9

         (i)      enforce the Pledge in respect of any or all of the Pledged
                  Assets, in accordance with applicable legal provisions;
                  and

         (ii)     apply any payments which may be received or receivable by
                  the Pledgee in respect of the Pledged Assets to
                  satisfaction of the Secured Obligations and as provided in
                  the Collateral Agency Agreement; and

         (iii)    exercise all rights and remedies it possesses, and to act
                  generally in relation to the Pledged Assets in such manner
                  as it shall determine within the limit of the applicable
                  law and its rights under this Agreement.

7.2      The Pledgee shall give the Pledgor not less than five (5) Business
         Days notice prior to the time that it first initiates legal action

         Pledgee shall not required to give notice pursuant to this sentence
         on more than one occasion subject to mandatory law requirements.

7.3      The Pledgee shall have no responsibility in connection with the
         enforcement measures of the Pledge under this Agreement, except in
         case of its gross negligence (grove fout/faute grave) or wilful
         misconduct.

8.       APPLICATION OF PROCEEDS

8.1      All monies received by the Pledgee after the Pledge has become
         enforceable shall be applied towards satisfaction of the Secured
         Obligations, including any costs and expenses of the Pledgee in
         accordance with Clause 4.1 of the Collateral Agency Agreement, but
         without prejudice to the rights of the Pledgee to recover any
         shortfall from the Pledgor.

8.2      Should the proceeds of the enforcement of the Pledge be greater
         than the outstanding amount of the Secured Obligations, the Pledgee
         shall pay to the Pledgor any such excess.

9.       DISCHARGE OF THE PLEDGE

9.1      This Pledge shall be discharged by, and only by, the express
         release thereof granted by the Pledgee.

9.2      The Pledgee shall in accordance with the Collateral Agency
         Agreement, grant an express release of this Pledge without delay
         upon demand of the Pledgor, as soon as all Secured Obligations
         shall have been fully and finally discharged and there is no
         possibility of any further Secured Obligation coming into
         existence.

9.3      Any release or discharge of the Pledge shall be null and void and
         without effect if any payment received by the Pledgee 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 Pledgee to a third party; or

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

         and the Pledgee shall be entitled to enforce the Pledge as if such
         release or discharge had not occurred.

         the Pledgee therefor, and its reimbursement obligation shall be
         part of the Secured Obligations.
