                                       4

<PAGE>

The Parent Company has opted for the tax regime applicable to certain groups of
French companies (hereinafter referred to as the "GROUP REGIME") provided by
Sections 223 A and subs.. of the GTC, for a term of five fiscal years, tacitly
renewable, as from April 1, 2004 (hereinafter referred to as the "CONSOLIDATION
PERIOD" or the "OPTION PERIOD"), by way of registered letter with return receipt
requested dated June 18, 2004. The Consolidated Companies granted their consent
to the creation of the Group by registered letter with return receipt requested
dated June 18, 2004. This Tax Consolidation Agreement replaces, nullifies and is
in lieu of any other tax consolidation agreement, which may have been entered
into by the companies parties hereto. This Tax Consolidation Agreement shall
become effective as from April 1, 2004.

The terms and conditions of this Agreement were approved by decisions of the
Boards of Directors of each of the Consolidated Companies.

Consequently, and in accordance with the provisions of Section 223 A paragraph 7
of the GTC, each Consolidated Company shall be jointly and severally liable for
the payment of Corporate Income Tax (hereinafter referred to as "CIT"), of
additional taxes complementing corporate income tax that are in effect on the
date of execution hereof or which are to become effective during the
Consolidation Period, of the minimum annual corporation tax ("imposition
forfaitaire annuelle des societes") referred to in Section 223 septies of the
GTC (hereinafter referred to as "IFA"), of the equalization tax ("precompte
mobilier") referred to in Section 223 sexies of the GTC (hereinafter referred to
as "PRECOMPTE"), of the special 25% tax on any distribution of profits made in
2005, as set forth by Article 95 of the French Finance Bill for 2004, and, as
the case may be, of late interest, tax increases, penalties and related fines,
for the payment of which the Parent Company is or may be liable. This joint and
several obligation shall be limited to the amount of taxes and penalties that
would be due by this Consolidated Company had it not been a member of the Group.

The purpose of the Agreement is to set the terms and conditions of sharing of
CIT, of additional taxes complementing corporate income tax, of the Precompte,
of the special 25% tax on distribution of profits made in 2005, of IFA,
resulting from the Group Regime and the consequences of a Consolidated Company's
exiting the Group. The CIT, the additional contribution complementing the CIT,
the Precompte, the special 25% tax on distribution of profits made in 2005 and
the IFA are hereinafter referred to as "TAX".

The parties' mutual intent is that the application of the Group Regime results
in harming neither the Consolidated Companies nor their shareholders, nor the
Parent Company, in contemplation of what their situation would have been like,
absent any Group Regime. Notably, pursuant to the Agreement each Consolidated
Company shall bear a tax burden equal to that it would have borne had it not
been a member of the Group. Besides, potential tax savings resulting from the
application of the Group Regime shall remain allocated to the Parent Company
except as provided in article 1.6 of this Agreement.

                                       5

PARTIES HAVE AGREED AS FOLLOWS:

ARTICLE 1 DETERMINATION OF THE CONTRIBUTION PAID BY EACH CONSOLIDATED COMPANY TO
          THE PARENT COMPANY FOR THE IT

1.1   Each Consolidated Company which generates a net taxable profit, a long
      term capital gain, or both, during a fiscal year ended within the Option
      Period, shall pay the Parent Company, as contribution to the payment of
      CIT and of any additional taxes complementing CIT due by the Parent
      Company, an amount equal to the CIT and to the additional taxes which the
      aforementioned net taxable profit and/or capital gain would be subject to
      if the Group Regime was not applied (hereinafter referred to as the
      "CONTRIBUTION"). Therefore, for the purposes of determining such
      Contribution, the items which the Consolidated Company would be entitled
      to deduct absent any Group Regime will be deducted. In particular, the
      Consolidated Company shall be entitled to deduct its potential loss carry
      forwards.

      If a Consolidated Company generates a tax loss during the Option Period,
      it will not be entitled to any refund by the Parent Company in relation
      with such situation, even if the latter has opted for the carrying-back of
      Group losses and is consequently entitled to a tax refund by the French
      Tax Authorities.

1.2   For the purposes of this article, the IT rates applicable to the profits
      generated shall be, depending on the nature of the income:

      -     the normal rate, its temporary or permanent increases which may be
            decided by law; and

      -     the rate(s) applicable to long-term capital gains depending on their
            category, including any increases as referred to hereabove.

      The rates for additional taxes of any kind complementing CIT shall be
      those that would have applied to the Consolidated Company absent any Group
      Regime.

1.3   Each Consolidated Company shall pay its Contribution to the Parent Company
      at least ten days prior to the deadlines binding the Parent Company for
      the payment of the Group CIT and additional taxes to the Tax Authorities.

1.4   Each Consolidated Company shall record the tax burden that it should have
      assumed, had said company been taxed separately.

      Such burden shall correspond to the tax calculated on the profit indicated
      in tax form 2058-A-bis and 2058-B-bis, reduced by the prior losses of the
      Consolidated Company, tax credits, withholding taxes, research or training
      tax credits, which may be deducted from CIT.

                                       6

<PAGE>

1.5   In the event that a Consolidated Company were in a situation where, absent
      any tax consolidation, it would have been reimbursed a tax credit by the
      Tax Authorities, including:

      -     research tax credit generated during the consolidation, and/or

      -     training tax credit generated during the consolidation,

      which may not be deducted from said Consolidated Company's CIT, the amount
      which the Consolidated Company may have received in this regard shall be
      paid by the Parent Company to the said Consolidated Company.

1.6   Notwithstanding the foregoing, and for purposes of application of article
      20.1 of the Senior Facilities Agreement dated June 26, 2003 between AGZ
      Holding and Calyon (as assignee of Credit Lyonnais) as amended from time
      to time (the "SENIOR FACILITIES AGREEMENT", the Parent Company undertakes,
      for each fiscal year included in the Consolidation Period, to repay to AGZ
      Holding an amount equal to the tax saving which AGZ Holding would have
      recorded in its financial statements in its capacity as parent company in
      the tax consolidation of AGZ Holding group, had it remained parent company
      of such group and had it applied the tax consolidation agreement
      previously effective between AGZ Holding and its subsidiaries. It is
      understood that this reallocation shall not result in placing AGZ Holding
      in a less favorable or more favorable position that it would have been in
      had it remained the head of the tax consolidation group. This repayment
      shall be implemented as follows:

      AGZ Holding, within fifteen (15) days following the annual approval of its
      financial statements by its general shareholders' meeting (i) shall
      calculate the amount of the accounting profit related to the tax saving
      which would have been generated by the application of the tax
      consolidation agreement previously effective between AGZ Holding and its
      subsidiaries and (ii) shall notify such amount to the Parent Company.

      The Parent Company, within fifteen (15) days from the receipt of this
      information, shall pay said amount to AGZ Holding by way of bank wire.

      From a legal standpoint, this payment may, at the Parent Company's
      election, be effected by way of subsidy or of capital increase. There
      shall be not interest charged by the Parent Company to AGZ Holding on any
      payment made by the Parent Company to AGZ Holding pursuant to this
      Section.

      In case of payment by way of subsidy, the Parent Company and AGZ Holding
      agree that said subsidy shall not be taken into account for determining
      the taxable profit on which is based the Contribution owed by AGZ Holding
      to the Parent Company. In addition, within thirty days from the annual
      approval by its general shareholders' meeting of the financial statements
      relating to the fiscal year when said subsidy shall be paid, AGZ Holding
      undertakes to repay the Parent Company an equivalent amount, if:

      - AGZ Holding is authorized to make such repayment under the conditions
      set forth in the Senior Facilities Agreement and in the Trust Deed of July
      23, 2002, as amended from time to time, relating to the high yield notes
      issued by AGZ Finance, a Luxembourg subsidiary of AGZ Holding, (the "TRUST
      DEED");

                                       7

<PAGE>

      - AGZ Holding is not in default with respect to the provisions of the
      Senior Facilities Agreement and the Trust Deed;

      - AGZ Holding has the necessary cash in order to effect this payment
      without resorting to a loan.

      These conditions shall be appreciated at the date of the relevant
      repayment.

      Should these conditions not be satisfied, the amount which may not be
      reimbursed to the Parent Company shall be rolled over and shall be payable
      during the following fiscal year, subject to the satisfaction of the
      conditions listed hereabove.

      The provisions of this Section 1.6 shall cease to apply immediately when
      all the amounts due to the Lenders under the Senior Facilities Agreement
      shall have been repaid.

ARTICLE 2 IFA

2.1   Each Consolidated Company shall pay the Parent Company, at the latest ten
      days prior to the legal deadline, an amount corresponding to the amount of
      the IFA that it would have paid, had it not opted for the Group Regime.

2.2   As an exception, for the fiscal year opening April 1, 2004, AGZ Holding
      shall be substituted to the other Consolidated Companies for the payment
      of IFA and shall continue to pay, for the period in question, such amounts
      on behalf of the said companies.

ARTICLE 3 CIT INSTALLMENTS

3.1   For the fiscal year opening April 1, 2004 on the one hand, and for the
      first CIT installment of the fiscal year opening April 1st, 2005, AGZ
      Holding shall be substituted to the other Consolidated Subsidiaries for
      the payment of IT installments and shall continue to pay, for the period
      in question, said amounts on behalf of the said companies.

3.2   As from the fiscal year opening April 1, 2004, and except for the first
      CIT installment of such fiscal year, each Consolidated Company shall pay
      the Parent Company four installments calculated by applying the rate
      provided by Section 360 to Appendix III to the GTC, to the base defined at
      article 3.3 below.

3.3   The first installment of each fiscal year of application of the Group
      Regime payable to the Parent Company shall be based on the taxable profit
      that was used for the determination of the Contribution paid by the
      Consolidated Company for the fiscal year preceding the latest fiscal year
      ended.

      The three other installments for each fiscal year are based on the taxable
      profit that was used for the determination of the Contribution paid by the
      Consolidated Company for the latest fiscal year ended.

                                       8

<PAGE>

3.4   The Consolidated Company shall pay to the Parent company the amount of the
      CIT installments at the latest ten days prior to the legal deadline for
      paying the installments, as defined by Section 360 of Appendix III to the
      GTC.

3.5   As the case may be, the CIT installments surplus shall be reimbursed by
      the Parent Company to a Consolidated Company within thirty days following
      the deadline for the CIT balance payment.

ARTICLE 4 AVOIR FISCAUX AND TAX CREDITS

4.1   Each Consolidated Company shall transfer to the Parent Company the avoirs
      fiscaux and tax credit certificates attached to gains and income received,
      within thirty days from their receipt.

4.2   Avoirs fiscaux and tax credits attached to gains and income benefiting
      from the parent-subsidiary tax regime defined in Sections 145 and 216 of
      the GTC may be deducted from the gross amount of the Precompte or of the
      special 25% tax on distribution of profits made in 2005 due by the Parent
      Company in case of distribution.

ARTICLE 5 TRANSMISSION OF TAX RETURNS TO THE PARENT COMPANY

5.1   Each Consolidated Company shall transmit to the Parent Company its tax
      return and information necessary for the determination of consolidated
      result, as well as a statement of waived receivables and of direct and
      indirect subsidies granted between the Consolidated Company and another
      Consolidated Company, at least thirty days prior to the deadline for the
      Parent Company to file the consolidated result tax return.

5.2   Each Consolidated Company shall reimburse the Parent Company for the total
      amounts of interest, penalties and IT increases owed by the Parent Company
      for absence or delay in the filing of the consolidated result, if such
      lack or delay was caused by the late transmission to the Parent Company by
      the Consolidated Company of the returns and of the information indicated
      in the paragraph hereabove.

5.3   Each Consolidated Company shall reimburse the Parent Company for the fine
      provided at Section 1734 bis of the GTC, which may be due by the Parent
      Company for failing to mention, in the statement referred to at Section
      223 B of the GTC, the waivers of receivables or the direct or indirect
      subsidies that the Consolidated Company itself failed to mention to the
      Parent Company on the statement provided at paragraph 5.1 hereabove, as
      long the Parent Company was not a party to said waivers of receivables and
      direct and indirect subsidies.

ARTICLE 6 PRECOMPTE/SPECIAL TAX ON PROFITS DISTRIBUTION

6.1   Dividend distributions made by the Parent Company to its shareholders
      shall not be included within the scope of the relationships among
      Consolidated Companies. Accordingly, the Agreement's purpose shall not
      consist in dealing with the treatment of possible implications of
      Precompte on the distributions made by the Parent Company to its
      shareholders.

                                       9

<PAGE>

6.2   When the Precompte is payable by reason of a distribution made by a
      Consolidated Company of dividends that are not derived from the profit
      and/or a long-term capital gain made during the Option Period, the
      Precompte is borne by the Consolidated Company, which shall pay the
      corresponding amount to the Parent Company ten days before the legal due
      date of the Precompte, less the tax credits that would be offset against
      such Precompte in the absence of Group Regime.

6.3   The Consolidated Companies shall not withhold any amount corresponding to
      the Precompte due on the portion of the dividends derived from a profit
      and/or a long-term gain capital made during the Option Period, and paid to
      a shareholder other than the Parent Company. The Parent Company shall bear
      by itself the burden of the corresponding Precompte.

6.4   These provisions relating to the Precompte shall apply to the
      distributions of dividends made by the Consolidated Company until December
      31, 2004 included. Distributions of dividends, and more generally any
      distribution of profits made as from January 1st, 2005 will not be subject
      to the Precompte but to the special 25% tax set forth by the 2004 Finance
      Act.

SPECIAL TAX ON THE DISTRIBUTION OF PROFITS

6.5   The special 25% tax due by the Consolidated Company by reason of its own
      distributions of profits shall be paid by the Parent Company to the
      Treasury and then reimbursed by the Consolidated Company to the Parent
      Company in the same conditions as those applicable to the Precompte
      (paragraph 5.1).

6.6   However, any special tax paid to the Treasury by the Parent Company shall
      create, to the benefit of the latter, a claim on the Treasury equal to the
      paid tax. Such claim shall be offset by equal portions on the CIT due by
      the Parent Company over the three following fiscal years.

6.7   Consequently, the amount of special tax paid by the Consolidated Company
      to the Parent Company by reason of a distribution made as from January
      1st, 2005 by the Consolidated Company, shall constitute, for the
      Consolidated Company a claim on the Parent Company. The Parent Company
      shall reimburse the Consolidated Company the total amount of special tax
      paid by the latter in similar conditions to those that would have been
      applicable to the Consolidated Company should this company had not been
      consolidated, for the concerned fiscal years.

ARTICLE 7 SANCTIONS APPLICABLE TO LATE PAYMENTS MADE BY A CONSOLIDATED COMPANY
          TO THE PARENT COMPANY

7.1   When a Consolidated Company has not made a payment to the Parent Company
      at a date where the corresponding amount should have been paid pursuant to
      the provisions of the Agreement, it shall pay the Parent Company a
      surcharge based on the annual rate of the legal interest (hereinafter
      referred to as the "SURCHARGE").

7.2   Furthermore, if, by reason of the late payment of the Consolidated
      Company, the Parent Company is liable for default interest payment,
      penalties or tax surcharge superior to the

                                       10

<PAGE>

      Surcharge, the Consolidated Company shall reimburse the Parent Company all
      of the excess (i) of interest payment, penalties and tax surcharge due by
      the Parent Company by reason of the late payment of the Consolidated
      Company on (ii) the amount of Surcharge that the latter has already paid.

ARTICLE 8 EXIT OF A CONSOLIDATED COMPANY DURING THE OPTION PERIOD AND
          TERMINATION OF THE GROUP REGIME

8.1   A Consolidated Company can exit the Group (hereinafter referred as the
      "EXIT") providing that it gives the other Consolidated Companies a written
      notice at least six months prior to the end of a fiscal year, the Exit
      taking necessarily place the first day of the following fiscal year. The
      Parent Company undertakes to fulfill the formalities required for the
      implementation of the Exit.

8.2   The Exit of a Consolidated Company from the Group may also occur if one of
      the conditions required for the creation of a tax consolidation is no
      longer fulfilled, and especially, if the Parent Company holds directly or
      indirectly less than 95% of its stated capital.

8.3   Moreover, the three following situations will result in the termination of
      the Group Regime :

      -     the Parent Company breaks the option at the end of the Option
            Period;

      -     the Parent Company is the only member of the Group ;

      -     the Group does not meet one of the conditions stated in Article 223
            A of the GTC.

8.4   The Exit of a Consolidated Company shall not result in the termination of
      this Agreement, which shall continue to apply among the other Consolidated
      Companies.

8.5   Consequences of the Exit of a Consolidated Company from the Group or of
      the termination of the Group Regime :

      8.5.1 Increase of the consolidated result

            The Parent Company shall owe the additional tax that it will
            possibly have to pay in case of Exit from the Group by a
            Consolidated Company.

      8.5.2 CIT installments

            The provisions of Article 223 N.2 of the GTC, pursuant to which he
            Parent Company bears the payment of CIT installments for the leaving
            Consolidated Company for the 12-month period starting at the
            beginning of the fiscal year during which it leaves the Group,
            create a claim on the leaving Consolidated Company at the benefit of
            the Parent Company, on each of the installments due date. The
            corresponding claim shall be reimbursed by the Consolidated Company
            on the date of the Exit, at the latest, for the installments already
            paid, and for the others, ten days prior to their legal due date.
            The Consolidated Company shall

                                       11

<PAGE>

            grant the Parent Company, in guarantee for the payment of such
            amounts, any security that the latter could reasonably request.

      8.5.3 Consolidation termination agreement

            The Parent Company and the exiting company shall agree on the
            drafting of a consolidation termination agreement.

ARTICLE 9 TAX ADJUSTMENTS

9.1   The Parent Company, as the unique person liable for tax, shall bear
      towards the tax administration the consequences of the adjustments made on
      the tax profits of each of the Consolidated Company for the fiscal years
      during which the Group Regime applies.

9.2   Consequently, if the profits of a Consolidated Company, for a fiscal year
      during which the Group Regime applies, are subject to adjustments
      (hereinafter referred as the "ADJUSTMENTS"), the Consolidated Company that
      has suffered the Adjustments shall pay the Parent Company a sum
      corresponding to the additional taxations and to the interest and
      penalties paid pursuant to the Adjustments and calculated in accordance
      with the provisions of this Agreement, ten days prior to the due dates.

9.3   The Consolidated Company shall assume the responsibility of challenging
      the Adjustments. It may choose any counsel to do so. The Consolidated
      Company shall bear the costs and fees relating to the challenging of the
      Adjustment. The strategy and defenses to be used shall be determined by
      the Consolidated Company with prior consent of the Parent Company on the
      said strategy as well as on any other contemplated compromise or
      transaction.

9.4   The Parent Company shall have access to any document that is in possession
      of the Consolidated Company and that would be necessary for the
      challenging of the Adjustments.

9.5   The provisions of Sections 9.2, 9.3 et 9.4 above shall apply similarly
      during or after the Option Period and before or after the Exit.

      If the examination of the accounts of a Consolidated Company for a fiscal
      year belonging to the Option Period takes place after the Option Period or
      after the Exit, the Parent Company shall communicate to the Consolidated
      Company and the Consolidated Company shall communicate to the Parent
      Company within 8 days from the receipt of a copy of all notice of
      examination of accounts, or notice of adjustments, or objections or
      document relating, directly or indirectly, to the examination of accounts
      procedure.

9.6   The Parent Company shall return to the Consolidated Company any tax relief
      and payment of late interest that the latter is entitled to upon the
      granting of a refund, in the limit of what it would have received from the
      tax administration should it have not been a member of the Group.

                                       12

ARTICLE 10 TERM

This Agreement is concluded for a term of five fiscal years, as from April 1st,
2004.

It will be automatically renewed, for the same term, at each renewal of the
option by the Parent Company.

The term of 5 years as provided in paragraph 1 hereabove shall not apply in
cases of Exit from the Group by a Company or of termination of the Group. In
these cases, the parties shall stay bound by their obligations, by reason of
their membership to the Group, until they effectively fulfill these obligations.
That will be specially the case when a tax control, taking place after the Exit
from the Group by a Company or at the termination of the Group, concerns a
fiscal year during which the Group Regime did apply.

ARTICLE 11 CONSOLIDATION OF NEW SUBSIDIARIES

This Agreement with all its provisions shall continue to apply in case of
consolidation of new subsidiaries by the Parent Company. Upon their joining the
Group, these new subsidiaries shall enter this Agreement by signing an amendment
with all the parties to the Agreement.

this Agreement shall be submitted to the jurisdiction of the Commerce Tribunal
of Nanterre.
