WHEREAS

(A)    The Pledgor and the Noteholders have agreed to amend and restate the
       Pledgor's euro 200,000,000 6.25 percent Notes due 2005, as amended and
       restated, the euro 200,000,000 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 Pledgor and the Noteholders party thereto (as
       amended, modified or supplemented from time to time, the AGREEMENT OF
       UNDERSTANDING). In connection with the Notes, the Pledgor will enter
       into a Fiscal Agency Agreement dated on or about the date of this
       Agreement among the Pledgor, 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 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 Pledgor pledge its shares in the
       Company (as defined below) to the Pledgee to secure its obligations
       to the Pledgee as provided herein and undertake the obligations
       contemplated by this Agreement.

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

(D)    The Pledgor is the legal and beneficial owner of the entire share
       capital of Amcis AG (AMCIS or COMPANY), a stock corporation
       (Aktiengesellschaft) organised under the laws of Switzerland,
       having its corporate seat at Hauptstrasse 159, CH-4416 Bubendorf,
       Switzerland, which is registered in the Commercial Register
       (Handelsregister) of the Canton of Basel-Landschaft, under

       (b)    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.

       (c)    The Pledgee or, as the case may be, Requisite Noteholders may
              at any time without discharging or in any way affecting this
              Pledge (a) grant the Pledgor or any Subsidiary Guarantor any
              time or indulgence, (b) concur in any moratorium of the
              Secured Obligations, (c) amend the terms and conditions of the
              Secured Obligations in accordance with the provisions of the
              Terms and Conditions of Notes and the applicable laws,
              (d) abstain from taking or perfecting any other security and
              discharge any other security, (e) abstain from exercising any
              right or recourse or from proving or claiming any debt and
              waive any right or recourse and (f) apply any payment received
              from the Pledgor or for its account towards the Secured
              Obligations or any other obligations of the Pledgor of the
              Pledgee's choice.

8.2.   Rights Additional

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

8.3.   Preservation of Security in Case of Transfer

       Without prejudice to the scope of the Secured Obligations, the
       Pledgor and the Pledgee agree that in the event of 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 Pledgee or the Pledgor in accordance
       with the Credit Documents, this Pledge will be maintained,

                                                                      - 11 -
- ----------------------------------------------------------------------------

       automatically and without any further formality or consent, to
       secure the Secured Obligations as assigned or novated in favour of
       the Pledgee (or the new Pledgee, if any). To the extent that any
       such further formality or consent on the part of Pledgor or of the
       Company will, nevertheless, be required, Pledgor hereby undertakes
       to perform, and to have the Company perform, any such formality or
       consent without delay upon the Pledgee's request.

9.     ENFORCEMENT

9.1.   At any time after the occurrence of an Event of Default which is
       continuing, the pledge created hereunder shall become immediately
       enforceable and the Pledgee shall in particular have the right,
       subject to the Collateral Agency Agreement and to the Terms and
       Conditions of Notes, to:

       (a)    enforce the Pledge in respect of any or all of the Shares, in
              accordance with applicable legal provisions and as set forth
              in this Agreement; and

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

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

9.2.   When exercising its right to enforce the Pledge after the
       occurrence of an Event of Default which is continuing, the Pledgee
       shall be entitled, at its discretion,

       (a)    to sell all or part of the Shares either through public
              auction (offentliche Versteigerung) or in a private sale
              (Selbstverkaufsrecht), without regard to the procedures and
              formalities provided for in the Swiss Federal Act Debt
              Collection and Bankruptcy of 1889, as amended, and without any
              notice thereof to the Pledgor other than a notice intending to
              inform the Pledgor that a sale of the Shares will take place,
              this notice being sent in accordance with Clause 14.6 of this
              Agreement to the Pledgor no later than 10 (ten) Business Days
              prior to such sale; or

       (b)    notwithstanding the foregoing and the provisions of Art. 41 of
              the Swiss Federal Law on the Recovery of Debts and Bankruptcy
              or any other applicable law, to institute and pursue the
              ordinary procedure for recovery of




                                                            Execution version

                                                                      - 12 -
- ----------------------------------------------------------------------------

              debt without having first to dispose of the Shares or to
              institute statutory proceedings for the realization thereof.

9.3.   The Pledgee has the right to acquire for itself all or any part of
       the Shares in any such public auction or private sale
       (Selbsteintrittsrecht). In case of an acquisition of the Shares by
       the Pledgee in a private sale, such sale has to be at arm's length,
       i.e. at the real value (the REAL VALUE (wirklicher Wert)) of the
       acquired Shares. If the Pledgor and the Pledgee do not reach an
       agreement on the Real Value within 30 calendar days following the
       Pledgee's corresponding offer, the Real Value shall be determined by
       an independent expert to be mutually appointed by the Parties. The
       expert's determination of the Real Value shall be final
       (Schiedsgutachten). If the parties cannot, within 60 days following
       the Pledgee's offer, agree on the expert to be appointed, the
       independent expert shall be appointed by the president of the
       "Treuhand-Kammer", Zurich, Switzerland.

9.4.   In view of a realization of the Pledge in accordance with the terms
       and conditions set forth above, the Pledgor, being the sole owner
       and holder of the Shares, hereby expressly declares its approval of
       the assignment and transfer of the Shares being subject to such
       realization to the acquirer of such Shares. The Pledgor further
       agrees that the respective acquirer will hold the Shares following
       their assignment and transfer and Pledgor will see for it that such
       acquirer will without any delay be entered in the Company's share
       register as the owner of the Shares.

9.5.   The proceeds from the realization of the Pledge shall be applied to
       towards the Secured Obligations, including any costs and expenses
       of the Pledgee, in accordance with the Collateral Agency Agreement,
       but without prejudice to the rights of the Pledgee to recover any
       shortfall from the Pledgor.

10.    DURATION AND RELEASE

10.1.  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 Pledgee to the Pledgor. The Pledge shall not cease
       to exist if any payments made in satisfaction of the Secured
       Obligations have only temporarily discharged the Secured
       Obligations.

10.2.  This Pledge is in addition to any existing or future collateral,
       guarantee or other security held by the Pledgee.

                                                                      - 13 -
- ----------------------------------------------------------------------------

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

10.4.  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.

10.5.  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.

11.    DUTIES OF THE PLEDGEE

       The Pledgee shall not be liable for any acts or omissions with respect
       to the Shares or the enforcement or the losses arising in connection
       with the exercise of any of its rights, powers and discretions
       hereunder, save for liabilities and expenses arising from the gross
       negligence or willful misconduct of the Pledgee. The Pledgee shall
       not be under any obligation to the Pledgor to take any steps
       necessary to preserve any rights in the Shares 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
       Pledgor and shall be part of the Secured Obligations. If any such
       expenses are borne by the Pledgee, the Pledgor shall on first demand
       reimburse the Pledgee therefor, and its reimbursement obligation
       shall be part of the Secured Obligations.

12.    EXPENSES AND COSTS

       All expenses that the Pledgee may incur in connection with (i) the
       administration of this Agreement as further provided in the
       Collateral Agency Agreement, (ii) the custody or preservation of,
       or the sale of, collection from, or other realization upon, any of
       the Shares, (iii) the exercise or enforcement of any of the rights
       of the

                                                                      - 14 -
- ----------------------------------------------------------------------------

       Pledgee hereunder, or (iv) the failure by the Pledgor to perform or
       observe any of the provisions hereof, shall be borne by the Pledgor. All
       other expenses and duties reasonably incurred in connection with this
       Agreement, in particular with regard to the establishment and
       perfection of the Pledge, its enforcement and the granting of any
       release, shall be borne by the Pledgor. The Pledgor shall on first
       demand reimburse the Pledgee for any such expenses or duties paid by
       it, and the same shall be part of the Secured Obligations.

13.    TAXES

       The Pledgor shall pay, promptly on demand of the Pledgee all stamp,
       registration, notarial and other similar Taxes or fees paid or
       payable by the Pledgee in connection with any action taken or
       contemplated by or on behalf of the Pledgee for perfecting,
       enforcing, releasing, canceling, reassigning or resolving any doubt
       concerning, or for any other purpose in relation to this Agreement,
       any amendment thereto, any transfer and/or assignment of the rights
       and/or obligations under the same or the Security created or
       intended to be created in respect of the Share and shall, from time
       to time, indemnify the Pledgee promptly on demand against any
       liabilities, costs, claims and expenses resulting from any failure
       to pay by the Pledgor or any delay by Pledgor in paying any such
       Taxes or fees.

14.    MISCELLANEOUS

14.1.  During the continuation of this Agreement, so long as no Event of
       Default has occurred and is continuing, the Pledgee will not
       declare itself to be the beneficial owner of the Shares or any
       additional pledged shares and the Pledgee may disclose and deliver
       a copy of the present Agreement to any tax or other authority, if
       asked to do so.

14.2.  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).

- ----------------------------------------------------------------------------

14.3.  Notwithstanding any provision to the contrary contained herein, the
       parties hereto agree that this Agreement is subject in all respects
       to the terms of the Collateral Agency Agreement and for the
       avoidance of doubt, in the event of any inconsistency, the
       provisions of the Collateral Agency Agreement shall prevail.

14.4.  No modification or amendment of this Agreement shall be binding
       upon any party hereto unless such modification or amendment shall
       be in writing and signed a duly authorized officer of the Pledgee
       and the Pledgor.

14.5.  No failure or delay by a party hereto 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 Pledgee hereunder shall be in addition to any
       other right vested in the Pledgee and all such rights may be
       exercised from time to time and as often as the Pledgee may deem
       expedient. The Pledgor waives any right it may have of first
       requiring the Pledgee to proceed against or claim payment from any
       other party, or enforce any guarantee or security before enforcing
       the Pledge.
