                                       5.
<Page>
    5.2  INDEMNITY PROCEDURES.  If Buyer shall become aware of facts which give
rise or threaten to give rise to Seller's obligations to indemnify Buyer
pursuant to this section ("EVENT SUBJECT TO INDEMNIFICATION"), regardless of
whether or not the Event Subject to Indemnification involves a third party,
Buyer shall send written notice (the "NOTIFICATION") to Seller promptly and in
no event later than within one half of the period granted for the settlement of
the obligation or the presentation of a defense after discovery of the Event
Subject to Indemnification disclosing the details thereof, and Seller shall
respond within 5 (five) calendar days as of the receipt of Notification (or
sooner, if circumstances require), PROVIDED, HOWEVER, that no delay in
delivering any Notification shall relieve Seller from its obligations hereunder
unless (and then solely to the extent that) Seller is prejudiced thereby,
especially (but not only) as a result of not being able to file the proper
defense because of the lack of time.

        (a) If an Event Subject to Indemnification shall arise which does not
    involve any third party, Seller shall send a written response to Buyer in
    which it states its intention to either (i) pay the amount involved or
    commence any required remedial measures in connection with the Event Subject
    to Indemnification; (ii) refuse to accept the event as an Event Subject to
    Indemnification; or (iii) discuss the matter. If (i), Seller will either pay
    the amount involved or commence any required remedial measures, in either
    case within 30 (thirty) days from the date of Notification. If (ii), Buyer
    may, at its option, commence any required action to pursue or defend its
    rights and remedies. If (iii), the Parties shall discuss the issues involved
    during a period of 30 (thirty) days from the receipt of the Notification,
    and if they reach an agreement, any payment required thereby shall be made
    by Seller to Buyer (in the case of monetary loss) or commenced by Seller (in
    the case of remedial measures) within 45 (forty-five) calendar days from the
    receipt of Notification. If they do not reach an agreement, Buyer may
    commence, at its option, any required action to pursue its rights and
    remedies.

        (b) If an Event Subject to Indemnification shall arise which involves
    any third party, the Seller's response shall indicate its intention either
    to (i) pay the amount involved; (ii) assume the defense of the litigation or
    proceeding, which it shall have the right to do (in which case, Seller shall
    be responsible for all costs, expenses, legal and court fees, as well as any
    guaranties which may be required to be placed for the respective defense
    ("DEFENSE COSTS"), and Buyer shall have the right to retain its own counsel
    at its own expense to monitor the defense); or (iii) not assume the defense
    of the litigation or proceeding, in which case they shall nevertheless be
    liable for the Defense Costs of Buyer and/or the Company in connection
    therewith. Whichever Party assumes the defense shall be entitled to the
    cooperation of the other Party in preparing the defense. Buyer agrees to
    provide Seller with access to all of Buyer's files and records concerning
    said defense.

        (c) If an Event Subject to Indemnification involves the responsibility
    of Buyer and Seller, the Company shall always be the one to take all actions
    to defend its interests and the Parties shall pay all Defense Costs
    proportionally to their respective responsibilities.

        (d) If Buyer sends Notification in accordance with the foregoing
    Section 5.2 and Seller fail to respond within the above-mentioned period,
    such failure to respond shall be deemed as an acceptance to pay the amount
    involved or carry out the required remedial measures in connection with the
    Event Subject to Indemnification.

6.  CONFIDENTIALITY

    6.1  CONFIDENTIALITY. Each Party shall refrain from disclosing and shall
hold confidential the terms and conditions of this Agreement, including without
limitation, the consideration to be paid hereunder, except to the extent that
disclosure of such information is necessary or desirable for consummation of the
transactions contemplated hereby, demanded by any governmental authority,
required by applicable law or stock exchange regulations to which a Party is
subject, or with the consent of all other parties hereto.

rules or regulations. Antitrust approval filing fees shall be borne equally by
the Parties.

    7.2  EFFECT OF NON-APPROVAL. In the event that the Brazilian antitrust
authorities refuse to accept the transaction as contemplated hereunder or impose

Agreement, each Party to this Agreement will bear its respective expenses
incurred in connection with the preparation, execution, and performance of this
Agreement and the transactions contemplated hereby, including all fees and
expenses of agents, representatives, counsel and accountants.

    8.7  SEVERABILITY. If at any time subsequent to the date hereof, any
provisions of this Agreement shall be held by any court of competent
jurisdiction to be illegal, void or unenforceable, such provision shall be of no
force and effect, but the illegality or unenforceability of such provision shall
have no effect upon and shall not impair the enforceability of any other
provision of this Agreement.

    8.8  WAIVER. The rights and remedies of the Parties are cumulative and not
alternative. Neither the failure nor any delay by any Party in exercising any
right, power or privilege under this Agreement will operate as a waiver of such
right, power or privilege, and no single or partial exercise of any such right,
power or privilege will preclude any other or further exercise of such right,
power or privilege or the exercise of any other right, power or privilege. To
the maximum extent permitted by applicable law, (a) no claim or right arising
out of this Agreement can be discharged by one Party, in whole or in part, by a
waiver or renunciation of the claim or right unless in writing signed by the
other Party; (b) no waiver that may be given by a Party will be applicable
except in the specific instance for which it is given; and (c) no notice to or
demand on one Party will be deemed to be a waiver of any obligation of such
Party or of the right of the Party giving such notice or demand to take further
action without notice or demand as provided in this Agreement.

                                       8.

    8.9  ASSIGNMENT. The respective rights and obligations of the Parties under
this Agreement may not be assigned by Buyer or the Seller without the prior
written consent of the other; PROVIDED, HOWEVER, that Buyer may assign this
Agreement in whole or in part to any affiliate of Buyer upon prior written
notice to Seller, in which case Buyer shall continue jointly liable with the
respective assignee. In case the purchase is effected through an affiliate of
the Buyer, such affiliate shall also be required to make the representations and
warranties provided for in Section 4, hereunder.

    8.10  GOVERNING LANGUAGE. This Agreement is executed in the English
language, and all of its terms and provisions shall be construed in accordance
with the English language, which shall prevail, notwithstanding any translation
thereof, which may have been submitted for regulatory approval purposes.

    8.11  COUNTERPARTS. This Agreement may be executed in two (2) counterparts,
each of which shall be deemed an original, but all of which taken together shall
constitute one and the same instrument.
