         (the MORTGAGEE).

WHEREAS:

(A)      The Mortgagor and the Noteholders have agreed to amend and restate
         the Mortgagor's euro 200,000,000 6.25 percent Notes due 2005, as
         amended and restated, the euro 200,000,00 10.00 percent Senior
         Secured Notes due 2008 (together with the Terms and Conditions of
         Notes annexed thereto, as amended, modified or 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 Agreement of Understanding and
         Restructuring dated 30 January 2004 among the Mortgagor and the
         Noteholders party thereto (as amended, modified or supplemented
         from time to time, the AGREEMENT OF UNDERSTANDING). In connection
         with the Notes, the Mortgagor will enter into the Fiscal Agency
         Agreement dated 11 February 2004 among the Mortgagor, Kredietbank
         S.A. Luxembourgeoise as fiscal agent and paying agent, and KBC Bank
         NV as principal paying agent (as amended, modified or supplemented
         from time to time, the FISCAL AGENCY AGREEMENT). The Noteholders

         and are deemed to have notice of all of the provisions of the
         Fiscal Agency Agreement.

(B)      It is a requirement of the Agreement of Understanding and the Terms

         with the relevant Noteholder) of each and every obligation of the
         Mortgagor towards each of the Noteholders under the Notes and the
         Other Credit Documents to which the Mortgagor is party, and
         accordingly the Mortgagee will have its own independent right to

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

(D)      In consideration of the agreements set forth herein and in the

         set-off as against such other party, other than as expressly
         permitted by the Terms and Conditions of Notes.

Mortgagor, this Mortgage will be maintained, automatically and without any
further formality or consent, to secure the Secured Obligations as novated
and in favour of the Mortgagee or the new mortgagees.

4.5      SETTLEMENTS CONDITIONAL

Any release, discharge or settlement between the Mortgagor and the Mortgagee
shall be conditional upon no security disposition or payment to the
Mortgagee being void or set aside or ordered to be refunded and if such

         to the fullest extent permitted by law and the Collateral Agency

         preferential claims, the proceeds of the enforcement of the
         security created by this Agreement shall be applied towards
         satisfaction of the Secured Obligations in accordance with the
         Collateral Agency Agreement.

(b)      Should the proceeds of the enforcement of the Mortgage be greater
         than the outstanding amount of the Secured Obligations, the
         Mortgagee shall pay to the Mortgagor any such excess.

7.       INDEMNITY

The Mortgagor shall fully indemnify and pay on demand to the Mortgagee in

         de-registration thereof.

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