         CONDITIONS OF NOTES) pursuant to an Agreement of Understanding and
         Restructuring dated 30 January 2004 among the Grantor and the
         Noteholders party thereto (as amended, modified or supplemented
         from time to time, the AGREEMENT OF UNDERSTANDING). In connection
         with the Notes, the Grantor will enter into the Fiscal Agency
         Agreement dated 11 February 2004 among the Grantor, 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

                                     3



                                                             Execution copy

         Noteholders and the Couponholders are entitled to the benefit of,
         are bound by 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
         and Conditions of Notes that the Grantor grant this mortgage
         mandate to the Attorneys to secure its obligations to the
         Beneficiary as provided herein and undertake the obligations
         contemplated by this Mandate.

(C)      Pursuant to Clause 2.1 of the Collateral Agency Agreement (as
         defined below), the Beneficiary shall be the joint creditor
         (together with the relevant Noteholder) of each and every
         obligation of the Grantor towards each of the Noteholders under the
         Notes and the other Credit Documents to which the Grantor is party,
         and accordingly the Beneficiary will have its own independent right
         to demand performance by the Grantor of those obligations. There is
         as a result a joint creditorship under New York law between the
         Noteholders and the Beneficiary 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

         -    a building located at Scheldelaan 460 (the ANTWERP PROPERTY),

         provided that this Mandate shall only become effective for the
         Antwerp Property after the Gemeentelijk Havenbedrijf Antwerp has
         given its express consent to this Mandate and the Mortgages
         resulting from the exercise of this Mandate in relation to the
         Antwerp Property.

This Mandate and the Mortgage created pursuant to this Mandate and in
accordance with Clause 13.8(b) of this Mandate shall not include a mortgage
of the Grantor's immovable property and rights in Ghent and Antwerp to the
extent that such Mandate or Mortgage would violate the express and
enforceable provisions of the Master Operating Agreement effective as of
1 September 1997 between Monsanto Company and the Parent including its
appendixes between Monsanto Europe SA and the beneficiary thereunder,
binding on the Grantor under applicable law.

The mortgages to be granted pursuant to this Mandate also include all
present and future accessories regarded as immovable, and all present and
future improvements, including, amongst others, all erected or to be erected
buildings.

2.2      AMOUNT

The mortgages (hypotheken/hypotheques) may be granted up to the following
maximum aggregate amounts:

         (ii)     three years of interest calculated at the rate of 18%, or
                  such other rate as may be agreed between the parties, in
                  accordance with article 87 of the Mortgage Law

                                                         pro memorie/memoire

         (iii)    for accessories such as retaining fees, reinvestment and
                  broken funding, costs for subrogation and inscription,
                  expenses and fees concerning collection of debt, costs and
                  fees concerning the perfection, foreclosure, release and
                  preservation of the security, estimate and file costs as
                  well as all amounts exceeding the above mentioned
                  principal, because of accounting matured interests,

                                                               EUR 2,000,000

This Mandate and the mortgages which may result therefrom are joined to and
shall not impair the other personal or collateral security the Beneficiary
now has or will have in the future as security for the Secured Obligations.
The Beneficiary is entitled to release, reduce, amend or enforce other
security granted or permitted pursuant to the Terms and Conditions of Notes
in accordance with the terms and conditions of the agreements relating
thereto, without notice to Grantor in its capacity as grantor of the Mandate
hereunder and this will not reduce the obligations of Grantor in any way.

2.3      RANKING

Without prejudice to the security interests created or permitted pursuant to
the Terms and Conditions of Notes and without limitations to the exceptions
provided therein, the Grantor confirms that the Property to be encumbered by
the mortgages granted pursuant to this Mandate are and will remain free and
clear of any Liens, including any seizure, inscription, contractual liens
(voorrechten), transcriptions (kantmeldingen), with the exception of
Permitted Liens and all existing rights of way, easements and the like

a branch of activity or a universality of one or more Attorneys.

         Terms and Conditions of Notes or any other document, by the taking,
         variation, compromise, exchange, renewal or release of or refusal
         or neglect to perfect or enforce any right, remedy or security over
         the Property or by anything done or omitted which but for this
         provision might operate to exonerate the Grantor;

(f)      shall not in any way be prejudiced or affected by any change in the
         constitution or status of the Grantor or any other Person or by any
         legal limitation, disability, incapacity or other circumstances
         relating to the Grantor or any other Person, by any invalidity,
         illegality or unenforceability of the obligations of the Grantor or
         any other Person; and

(g)      the Beneficiary or, as the case may be, Requisite Noteholders may

realised or monies received pursuant to this Mandate for or on the account
of the liability of any other party:

         receivable by the Beneficiary or be entitled to any right of
         contribution or indemnity; or

         in competition with the Beneficiary; or

         security from or on account of any party, or exercise any right of
         set-off as against such other party, other than as expressly
         permitted by the Terms and Conditions of Notes.

In accordance with article 1278 of the Belgian Civil Code and without
prejudice to the scope of the Secured Obligations, the Grantor and the

will be maintained, automatically and without any further formality or
consent, to secure the Secured Obligations as novated and in favour of the
Beneficiary or the new beneficiaries.

4.5      SETTLEMENTS CONDITIONAL

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

enforce the security created by this Mandate as if such release, settlement
or discharge had not occurred and any such payment had not been made.

         fullest extent permitted by law and the Collateral Agency
         Agreement.

(b)      All enforcement costs will be considered as accessories to the main
         obligation and will be borne by the Grantor.

6.       APPLICATION OF PROCEEDS

(a)      Subject to the rights of any creditor with prior security or
         preferential claims, the proceeds of the enforcement of the
         security created by this Mandate shall be applied towards
         satisfaction of the Secured Obligations in accordance with the
         Collateral Agency Agreement.
