            validly served upon the Seller.

2.3.  Conduct of litigation

      (A)   Upon the Purchaser or the Company becoming aware of any claim,
            action or demand against it or matter likely to give rise to any of
            these in respect of the Warranties and Undertakings, the Purchaser
            shall and shall procure that the Company shall:

      (i)   within seven (7) Business Days from the date any assessment or claim
            made by a third party which may result in a claim under the
            Warranties or Undertakings is notified to the Company or the
            Purchaser, notify the Seller by written notice of such assessment or
            claim. The failure to notify the Seller shall not relieve the Seller
            of any liability that may have to the Purchaser, to the extent that
            the Purchaser may prove that the defence of such claim, action or
            demand by Seller has not been in any way harmed by the Purchaser's
            or the Company's failure to give such notice to the Seller;

      (ii)  take such action and give such information and access to personnel,
            premises, chattels, documents and records to the Seller and its
            professional advisers as the Seller may reasonably request and the
            Seller shall be entitled to require the Purchaser and/or the Company
            to take such reasonable action and give such reasonable information
            and assistance in order to avoid, dispute, resist, mitigate, settle,
            compromise, defend or appeal any claim in respect thereof or
            adjudication with respect thereto;

      (iii) at the request of the Seller, allow the Seller to take the conduct
            of such actions, as the Seller may deem appropriate in connection
            with any such assessment or claim in the name of the Purchaser
            and/or the Company and in that connection the Purchaser shall give
            or cause to be given to the Seller all such assistance as the Seller
            may reasonably require in avoiding, disputing, resisting, settling,
            compromising, defending or appealing any such claim and shall
            instruct such counsels or other professional advisers acceptable to
            the Purchaser or the Company, as the Seller may nominate to act on
            behalf of the Purchaser or the Company, as appropriate, but to act
            in accordance with the Sellers


                                       51
<PAGE>

            instructions. In this event the Seller shall pay all costs and
            expenses in any way related to such action (including legal fees);

      (iv)  unless the Seller fails, upon being notified by the Purchaser, to
            conduct the litigation relating to such claim or adjudication, make
            no admission of liability, agreement, settlement or compromise with
            any third party in relation to any such claim or adjudication
            without the prior written consent of the Seller, such consent not
            being unreasonably withheld; and

      (v)   take all reasonable action to mitigate any loss suffered by it
            and/or the Company in respect of which a claim could be made under
            the Warranties or the Undertakings.

      (B)   In any event, the Seller shall not be entitled at any stage to
            settle any such third party assessment or claim without the prior
            written consent of the Purchaser, such consent not being
            unreasonably withheld.

2.4.  No liability if loss is otherwise compensated for

      Purchaser can only claim once

      (A)   The Purchaser and those deriving title from the Purchaser on or
            after Completion shall not be entitled to recover damages or
            otherwise obtain reimbursement or restitution more than once between
            them in respect of any individual breach of the Warranties or claim
            under the Undertakings.

      (B)   No liability shall attach to the Seller by reason of any breach of
            the Warranties to the extent that the same loss occasioned to the
            Purchaser or the Company by reason of such breach has been recovered
            under the Undertakings and no liability shall attach to the Seller
            under the Undertakings to the extent that the same loss has been
            recovered by a claim under the Warranties given by it.

      (C)   The Seller shall not be liable for breach of any of the Warranties
            nor under any of the Undertakings to the extent that the subject of
            the claim has been or is made good or is otherwise compensated for
            without any cost to the Purchaser or to the Company.

      Insurances

      (D)   If, in respect of any matter which would give rise to a breach of
            the Warranties or a claim under the Undertakings, the Purchaser
            and/or the Company, as the case may be, is entitled to claim under
            any policy of insurance, then except for any amount to be paid by
            the


                                       52
<PAGE>


            Purchaser or the Company to the relevant insurer that exceeds
            R$100.000,00 (including, without limitation, deductibles and
            eventual retrospective premium adjustments) (such amounts being
            reimbursed by the Seller without the limitations set forth in this
            Schedule 2, provided the Seller is notified about such claim within
            60 days after the payment is made), no such matter shall be the
            subject of a claim under the Warranties or the Undertakings unless
            and until the Purchaser and/or the Company shall have made a claim
            against its insurers and any such insurance claim (or any claim
            which could have been made had such policies or their equivalents
            been maintained as aforesaid) shall then reduce by the amount
            recovered or extinguish any such claims for breach of the Warranties
            or under the Undertakings.

      Recovery from third parties

      (E)   If the Seller pays at any time to the Purchaser or the Company an
            amount pursuant to a claim in respect of the Warranties and/or the
            Undertakings or under any provisions of this Agreement and the
            Purchaser or the Company subsequently become entitled to recover
            from some other person any sum in respect of any matter giving rise
            to such claim, the Purchaser shall assign to the Seller the Right
            to, take all reasonably necessary steps to enforce such recovery,
            provided, however, that the excess of the sum recovered by the
            Seller from such other person less all costs, charges and expenses
            incurred by the Seller and the amount paid by the Seller to the
            Purchaser or the Company with respect to such claim, shall be
            promptly paid to the Purchaser or the Company.

2.5.  Acts of the Purchaser

      (A)   No claim shall lie against the Seller under the Warranties or
            Undertakings to the extent that such claim is wholly or partly
            attributable to any voluntary act, transaction or arrangement
            carried out at the request of or with the consent of the Purchaser
            before Completion.

      (B)   The Seller shall not be liable for any breach of Warranties or
            claims under the Undertakings which would not have arisen but for
            any reorganisation or change in ownership of the Shares after
            Completion or any changes in the accounting basis on which the
            Company values its assets or any other change in accounting policy.

2.6.  Allowance, provision or reserve in the Reference Balance Sheet


                                       53
<PAGE>

No matter shall be the subject of a claim for breach of any of the Warranties or
under the Undertakings to the extent that allowance, provision or reserve in
respect of such matter shall have been made in the Reference Balance Sheet or
has been included in calculating creditors or deducted in calculating debtors in
the Reference Balance Sheet and (in the case of creditors or debtors) is
identified in the records of the Company or shall have been otherwise taken
account of or reflected in the Reference Balance Sheet.

2.7.  Future legislation

No liability shall arise in respect of any breach of any of the Warranties or
under the Undertakings if and to the extent that liability for such breach
occurs or is increased as a result of any change after the date hereof of any
legislation, regulation, ordinance or ruling of any governmental, court or
regulatory authority or any interpretation of said authorities.

2.8.  Taxation

No claim shall arise in respect of any breach of any of the Warranties or in
respect of the Undertakings to the extent that such claim would not have arisen
but for:

      (1)   any increase in rates of Tax or any change in law or practice or any
            withdrawal of any extra-statutory concession by a tax authority or
            any change in accountancy practice or principles, being an increase,
            withdrawal or change made, in any such case, after the date of this
            Agreement; or

      (ii)  any changes after Completion in the bases, methods or policies of
            accounting of the Company, except to the extent that such changes
            are necessary to comply with relevant laws and regulations that were
            in force but were not complied by the Company before the Closing
            Date ; or

      (iii) a cessation of, or any change in the nature or conduct of, any trade
            carried on by the Company being a cessation or change occurring on
            or after Completion, except to the extent that such cessation or
            change was caused by an act that occurred on or before Completion;
            or

      (iv)  any differences between the bases, methods or policies of accounting
            of the Purchaser or any member of the Purchasers group and those of
            the Company, except to the extent that such bases, methods or
            policies of accounting of the Company did not comply with the
            relevant laws and regulations prior to the Effective Date.
