Agreement, on the Closing Date (as defined below) Seller hereby promises to
sell, assign and transfer the Quotas to Buyer, and Buyer hereby promises to

<PAGE>

2000 (the "CLOSING DATE"), or at such other date and/or place as the parties

the Signing Date.


                                  ARTICLE 3
                      PURCHASE PRICE; TERMS OF PAYMENT

3.1  PURCHASE PRICE. Subject to adjustments as set forth in Sections 3.4 and
3.5 hereof, the total purchase price (the "PURCHASE PRICE") for the purchased
Quotas is the amount in the Brazilian currency equivalent to the sum of
US$122,044,000.00 (One hundred twenty two million, forty four thousand U.S.
Dollars), comprised of (i) US$72,044,000.00 (Seventy two million, forty four
thousand U.S. Dollars) representing the net book value of the Transferred
Assets as set forth on the December Balance Sheet (the "DECEMBER BOOK VALUE
AMOUNT"), and (ii) US$50,000,000.00 (Fifty million U.S. Dollars) representing
a premium over the December Book Value Amount (the "PURCHASE PRICE PREMIUM").

3.2  EXCHANGE RATE. The conversion of the Purchase Price from U.S. Dollars
into Reais shall be computed by applying the average buy/sell commercial
exchange rate quoted by the Central Bank of Brazil (SISBACEN PTAX 800 -
Option 5) at the close of business on the day immediately preceding the
Closing Date.

3.3  METHOD OF PAYMENT. Payment of the Purchase Price shall be made on the
Closing Date by Buyer to Seller by check or by wire transfer of immediately
available funds to Seller to such account within Brazil as Seller shall
designate.

3.4  PRE-CLOSING PURCHASE PRICE ADJUSTMENT. Not later than three business
days prior to the Closing, Seller shall deliver to Buyer a good faith
estimate of the balance sheet of the Company as of the Closing Date (the
"CLOSING BALANCE SHEET"). At the Closing, (a) if the book value of the
Transferred Assets as set forth on the Closing Balance Sheet (the "CLOSING
BOOK VALUE AMOUNT") exceeds the December Book Value Amount, the Purchase
Price shall be increased by the amount of such excess, or (b) if the Closing
Book Value Amount is less than the December Book Value Amount, the Purchase
Price shall be decreased by the amount of such

                                      5

<PAGE>

deficit. The conversion method set forth in Section 3.2 above shall be
applied to convert the adjusted Purchase Price from U.S. Dollars into Reais
and for purposes of calculating the estimated Closing Balance Sheet. In
neither of the foregoing events shall the amounts of the Purchase Price
Premium be increased or decreased.

3.5  POST-CLOSING PURCHASE PRICE ADJUSTMENT. The Purchase Price shall be
subject to adjustment after the Closing Date, according to the specifications
mentioned below.

3.5.1 As soon as practicable following the Closing Date, but in any event
within sixty (60) calendar days following the Closing Date, Buyer shall
deliver to Seller an audited balance sheet of the Company as of the Closing
Date (the "POST-CLOSING BALANCE SHEET"), prepared by Buyer, together with a
report thereon from Buyer's independent accountant stating that the
Post-Closing Balance Sheet fairly presents the book value of the Transferred
Assets at the Closing Date in accordance with generally accepted Brazilian
accounting principles ("GAAP") applied on a basis consistent with the
preparation by Seller of the Closing Balance Sheet. In the event that Buyer
fails timely to deliver the Post-Closing Balance Sheet for any reason
whatsoever, the Closing Balance Sheet shall be deemed to be and shall be
final, binding and conclusive on Buyer and Seller and the Purchase Price
shall no longer be subject to adjustment.

3.5.2 Within twenty (20) business days following the delivery by Buyer of the
Post-Closing Balance Sheet, Seller may dispute any amount(s) reflected
thereon, but only on the basis that the amounts reflected thereon were not
arrived at in accordance with GAAP applied on a basis consistent with the
preparation by Seller of the Closing Balance Sheet; provided, however, that
Seller shall have notified Buyer and Buyer's independent accountant in
writing of each disputed item, specifying the amount thereof in dispute and
setting forth, in reasonable detail, the basis for such dispute, within
twenty (20) business days following Buyer's delivery of the Post-Closing
Balance Sheet to Seller. In the event of such a dispute, Seller's controller
and/or independent accountant and Buyer's independent accountant shall
attempt to reconcile their differences, and any mutually agreed resolution by
them as to any disputed amounts shall be deemed to be and shall be final,
binding and conclusive on Buyer and Seller. If Seller's controller and/or
independent accountant and Buyer's independent accountant are unable to

                                      6

<PAGE>

mutually reach a resolution with such effect within said twenty business days
after receipt by Buyer and Buyer's independent accountant of Seller's written
notice of dispute, Seller's controller and/or independent accountant and
Buyer's independent accountant shall submit the items remaining in dispute
for resolution to Arthur Andersen (the "INDEPENDENT ACCOUNTING FIRM"), which
shall, within thirty business days after such submission, determine and
report to Buyer and Seller upon such remaining disputed items, and such
report shall be deemed to be and shall be final, binding and conclusive on
Buyer and Seller. The fees and disbursements of the Independent Accounting
Firm shall be allocated between Buyer and Seller in the same proportion that
the aggregate amount of such remaining disputed items so submitted to the
Independent Accounting Firm that is unsuccessfully disputed by each such
party (as finally determined by the Independent Accounting Firm) bears to the
total amount of such remaining disputed items so submitted. In acting under
this Section 3.5, Seller's controller and/or independent accountant, Buyer's
independent accountant and the Independent Accounting Firm shall be entitled
to the privileges and immunities or arbitrators.

3.5.3 The Post-Closing Balance Sheet shall be deemed final for the purposes
of this Section 3.5 upon the earliest of (i) the failure of Seller to notify
Buyer of a dispute within twenty (20) business days following Buyer's
delivery of the Post-Closing Balance Sheet to Seller, (ii) the resolution of
all disputes, pursuant to Section 3.5.2, by Seller's controller and Buyer's
independent accountant, and (iii) the resolution of all disputes, pursuant to
Section 3.5.2, by the Independent Accounting Firm.

     Within three business days following the Post-Closing Balance Sheet
being deemed final, a Purchase Price adjustment shall be made and become due
and payable as follows: (i) if the book value of the Purchased Assets as set
forth on the Post-Closing Balance Sheet (the "POST-CLOSING BOOK VALUE
AMOUNT") exceeds the Closing Book Value Amount, the Purchase Price shall be
increased by the amount of such excess and Buyer shall pay over such excess
to Seller in accordance with Section 3.5.4 hereof, or (b) if the Post-Closing
Book Value Amount is less than the Closing Book Value Amount, the Purchase
Price shall be decreased by the amount of such deficit and Seller shall pay
over such deficit to Buyer in accordance with Section 3.5.4.

                                      7

<PAGE>

In neither of the foregoing events shall the amount of the Purchase Price
Premium be increased or decreased.

3.5.4   Buyer shall pay to Seller the amount by which the Post-Closing Book
Value Amount exceeds the Closing Book Value Amount, or Seller shall pay to
Buyer the amount by which the Closing Book Value Amount exceeds the
Post-Closing Book Value Amount, as applicable, by a wire transfer of
immediately available funds in Reais, according to the conversion method from
U.S. Dollars into Reais set forth in Section 3.2 herein, to such bank account
or accounts as the party to receive such payment may specify in writing to
the other party. Any such payment shall also include simple interest on the
amount of such payment, calculated at the annual (365 day) rate of eight and
one half percent (8.5%) and accruing from the Closing Date through (but not
including) the date on which such payment is made.

                                  ARTICLE 4

Assets to the Company and until the closing of the Buyer's acquisition of the

the obligations required to be performed by it under the Assigned Contracts,
and is entitled to all benefits thereunder and is not in default or alleged

Manufacturing Operation on such date. Such inventories do not include any

deterioration in the value of the inventory owned by Seller or the Company,
as the case may be, in connection with the Manufacturing Operation since

with the Manufacturing Operation at amounts required for the operation of the
Manufacturing Operation and will continue to be maintained by Seller or the
Company, as the case may be, at such levels until the Closing Date.

                                 INDEMNIFICATION

5.1     LIABILITY. In accordance with the procedures set forth in Section 5.2
below and subject to the limitations set forth in Section 5.3 below, Seller
agrees to indemnify and hold Buyer and the Company harmless from any loss or
damage resulting from or due to breach of any representation, warranty,
covenant or agreement of Seller contained herein or in any document delivered
hereunder.

5.2     INDEMNIFICATION PROCEDURES. If Buyer or the Company shall become
aware of facts which give rise or threaten to give rise to Seller's
obligation to indemnify Buyer or the Company pursuant to Section 5.1 hereof
(hereinafter referred to as an "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 after discovery of the Event Subject to Indemnification disclosing
the details thereof. Subject to Paragraph (b) below, failure to notify Seller
shall release Seller from any liability that it may have to Buyer and/or the
Company. Seller shall respond within thirty (30) calendar days of receipt of
the Notification (or sooner, if a third party is involved and circumstances
require, in which case a shorter period shall be stated in the Notification).
Seller shall only be responsible

                                       15



<PAGE>

for indemnification hereunder if the respective claim is awarded by means of
a final and irrevocable judgement, not subject to any further defense or
appeal.

(a)  If the Event Subject to Indemnification does not involve any third
     party, then Seller's response shall indicate its intention to (i) pay
     the amount involved or commence any required remedial measures in the
     Event Subject to Indemnification; (ii) refuse to accept the event as an
     Event Subject to Indemnification; or (iii) discuss the matter.

     --   If option (i) is elected, Seller will either pay the amount
          involved, or commence any required remedial measures in the Event
          Subject to Indemnification, in either case within 30 days from the
          date of Notification.

     --   If option (ii) is elected, Buyer or the Company may, at its option,
          commence any required action to pursue or defend its rights and
          remedies.

     --   If option (iii) is elected, the parties shall discuss the issues
          involved during a period of 30 days from receipt of the
          Notification, and if they reach an agreement, any payment required
          thereby shall be made (in the case of payment) or commenced (in the
          case of remedial measures) by Seller to Buyer or the Company within
          45 calendar days from receipt of the Notification.

(b)  If the Event Subject to Indemnification involves any third party, then
     Seller's response shall indicate its intention (i) to assume the defense
     of the litigation or proceeding, which it shall have the right to do, in
     which case, Buyer and the Company shall each have the right to retain
     their own counsel at their own expense; or (ii) not to assume the
     defense of the litigation or proceeding, in which case it shall
     nevertheless be liable for expenses of Buyer and/or the Company in
     connection therewith.

(c)  Any failure by Seller to respond within the strict time limits specified
     in this Section 5.2 shall give rise to further liability only if and to
     the extent that Buyer or the Company can

                                     16

     failure to respond in timely fashion.

to indemnify set forth in Section 5.1 above shall apply:

(a)  The aggregate losses subject to indemnification hereunder shall not
     exceed **** of the Purchase Price.

(b)  Seller shall not be liable to Buyer for any single event subject to
     indemnification unless it results in an actual loss in an amount equal
     to or greater than ****.

(c)  As to events subject to indemnification that result in actual losses
     equal to or greater than ****, Seller shall not be required to make
     payment until the aggregate of such losses equals or exceeds ****, for
     which purpose Buyer shall notify Seller of each such actual loss at
     which time Seller shall be required to make payment for all losses
     subject to the provisions of Section 5.3(b) above including the first
     ****.

(d)  The indemnification obligations of Seller contained in this Agreement
     shall terminate **** after the Closing Date except for the
     indemnification obligations in respect of (i) the representations and
     warranties contained in Sections **** and the **** which shall survive
     ****; and (ii) the representation and warranty in section **** which
     shall survive until ****.

                                     17

<PAGE>

(e)  If any indemnifiable loss is a tax deductible item for the Company
     and/or Buyer, the indemnification hereunder shall be reduced by the tax
     rate which is applicable at the time of the payment.

from the constitution of the arbitration tribunal, or from the substitution
of an arbitrator. It shall be final and binding upon all the Parties and
shall be enforceable in accordance with its terms and conditions.

10.10.3  The cost of the arbitration, including a reasonable allowance for
attorneys' fees, shall be borne by the losing party or as otherwise specified
in the ruling of the arbitration tribunal. All proceedings and records of the
arbitration shall be conducted and maintained in Portuguese.

10.10.4   The parties agree that the award is to be considered as a
settlement of the dispute between them and shall accept it as the true
expression of their own determination in connection therewith.

10.10.5   The parties agree that either party may, in certain circumstances,
need to obtain immediate relief from the court. Therefore, the filing for and
obtaining of injunctive relief (or another type of remedy which cannot be
obtained from an arbitration tribunal under Brazilian law) in connection with
this Agreement shall be accepted, and shall not be considered a breach
hereof. In this case, the competent court shall be the court of Sao Paulo,
State of Sao Paulo, Brazil.

10.11     EXPENSES. Whether or not the transactions contemplated hereby are
consummated, the parties hereto shall pay their own respective expenses.

10.12     SEVERABILITY. If any provision of this Agreement is 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.

10.13     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 (collectively, "RIGHT"), and no single or
partial exercise of any Right will preclude any other or further exercise of
such or other Right. 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.

shall not be assignable by Buyer or Seller without the prior written consent
of the other party; provided that the Buyer may assign its rights and
obligations hereunder to any wholly-owned subsidiary of Buyer.

10.16     COUNTERPARTS. This Agreement shall be executed in five
counterparts, each of which shall be deemed an original, but all of which
taken together shall constitute one and the same instrument.

10.17     LANGUAGE; ATTACHMENTS. This Agreement shall be executed in English
and Portuguese. In the event of a discrepancy between the English and the
Portuguese version, the English-language version shall prevail. The
Attachments to this Agreement shall be in Portuguese.
