                        12% Senior Secured Notes due 2004

         Capitalized terms used herein but not defined will have the meanings
assigned to them in the Indenture referred to below unless otherwise indicated.

         1.       INTEREST.

         On any of the first four Interest Payment Dates occurring after the
date of the Indenture, interest on the Notes shall, at the option of the
Company, be paid in kind instead of in cash. Upon such an event, the Company
will issue to Holders of the Notes on any such Interest Payment Date, and the
Trustee will authenticate, an additional Note substantially in the form hereof
registered in the name of such Holder and having a principal amount equal to the
amount of interest paid in kind on all of the outstanding Notes held by such
Holder on such Interest Payment Date. The Notes will mature on December 20,
2004. The Company promises to pay interest on the principal amount of this Note
from December 20, 1999 until maturity. The Company will pay interest
semi-annually on June 20 and December 20 of each year, commencing December 20,
2000, or if any such day is not a Business Day, on the next succeeding Business
Day (each an "Interest Payment Date"). Interest on the Notes will accrue at the
rate of 12% per annum from the most recent date to which interest has been paid
or, if no interest has been paid, from December 20, 1999. The Company will pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law to the extent that such interest is an allowed claim enforceable
against the debtor under such Bankruptcy Law) on overdue principal and premium,
if any, from time to time on demand at the rate equal to 1% per annum in excess
of the then applicable interest rate on this Note to the extent lawful; it will
pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law to the extent that such interest is an allowed claim against the
debtor under such Bankruptcy Law) on overdue installments of interest (without
regard to any applicable grace periods) from time to time on demand at the same
rate to the extent lawful. Interest will be computed on the basis of a 360-day
year comprised of twelve 30-day months.

         2.       METHOD OF PAYMENT.

         The Company will pay the principal of, and premium, and interest on,
the Notes on the dates and in the manner provided herein and in the Indenture.
Principal, premium, if any, and interest on, Certificated Notes will be payable,
and Certificated Notes may be presented for registration of transfer or
exchange, at the office or agency of the Company maintained for such purpose.
Principal of, and premium and interest on, Global Notes will be payable by the
Company through the Trustee to the Depository in immediately available funds.
Holders of Certificated Notes will be entitled to receive interest payments by
wire transfer in immediately available funds if appropriate wire transfer
instructions have been received in writing by the Trustee not less than 15
calendar days prior to the applicable Interest Payment Date. Such wire
instructions, upon receipt by the Trustee, will remain in effect until revoked
by such Holder. If wire instructions have not been received by the Trustee with
respect to any Holder of a Certificated Note, payment of interest may be made by
check in immediately available funds mailed to such Holder at the address set
forth upon the Register maintained by the Registrar.

         3.       PAYING AGENT AND REGISTRAR.

         Initially, Deutsche Trust Bank Limited will act as principal Paying
Agent, and The Bank of New York, the Trustee under the Indenture, will act as
Registrar. The Company may change any Paying Agent or Registrar in accordance
with the terms of the Paying Agent Agreement. The Company or any of its
Subsidiaries may act in any such capacity, PROVIDED, HOWEVER, that none of the
Company, its Subsidiaries or the Affiliates of the foregoing will act (i) as
Paying Agent in connection with any redemption, offer to purchase, discharge or
defeasance, as otherwise specified in the Indenture, and (ii) as Paying Agent or
Registrar if a Default or Event of Default has occurred and is continuing.

         4.       INDENTURE.

         The Company issued the Notes under an Indenture dated as of July 20,
2000 (as such may be amended, supplemented or restated from time to time, the
"Indenture") between the Company and the Trustee. The terms of  the Notes

                                       2
<PAGE>

include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections
77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred
to the Indenture and such Act for a statement of such terms. The Notes are
senior obligations of the Company ranking PARI PASSU in right of payment with
all existing and future senior Indebtedness of the Company and ranking senior in
right of payment to any future subordinated Indebtedness of the Company.

         5.       OPTIONAL REDEMPTION.

         The Notes will be subject to redemption at the option of the Company,
in whole or in part, upon not less than 30 nor more than 60 days' notice, at the
redemption prices (expressed as percentages of principal amount) set forth
below, plus accrued and unpaid interest if any, thereon to the applicable
redemption date, if redeemed during the twelve month period beginning on
December 20 of the years indicated below:

                Year                                 Percentage
               ------                               -------------

                2000                                 106.4375%

                2001                                 104.2917%

                2002                                 102.1458%

                2003 and thereafter                  100.0000%

         6.       MANDATORY REDEMPTION.

         Except as set forth in paragraph 7 below, the Company will not be
required to make mandatory redemption or sinking fund payments with respect to
the Notes.

         7.       REPURCHASE AT OPTION OF HOLDER.

         (a)    Upon a Change of Control, the Company will be required to make
an offer to Holders to repurchase all or any part (equal to US$1,000 or an
integral multiple thereof) of each Holder's Notes at an offer price in cash
equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid
interest thereon to the date of repurchase as provided in, and subject to the
terms of, the Indenture.

         (b)    If the Company or any Restricted Subsidiary consummates any
Asset Sale, the Company may be required, subject to the terms and conditions of
the Indenture, to utilize a certain portion of the proceeds received from such
Asset Sale to repurchase Notes at a purchase price equal to Net Proceeds Offer
Price on the Net Proceeds Purchase Date.

         8.       DENOMINATIONS, TRANSFER, EXCHANGE.

         The Notes are in registered form without coupons in denominations of
US$1,000 and integral multiples of US$1,000. The transfer of Notes may be
registered and Notes may be exchanged as provided in the Indenture. The
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and the Company may require a
Holder to pay any taxes and fees required by law or permitted by the Indenture.
The Company need not exchange or register the transfer of any Note or portion of
a Note selected for redemption, except for the unredeemed portion of any Note
being redeemed in part. Also, it need not exchange or register the transfer of
any Notes for a period of 15 calendar days before a selection of Notes to be
redeemed or during the period between a record date and the next succeeding
Interest Payment Date.

         9.       PERSONS DEEMED OWNERS.

         The registered Holder of a Note may be treated as its owner for all
purposes.

                                       3

<PAGE>

         10.      UNCLAIMED MONEY.

         If money for the payment of principal, premium or interest remains
unclaimed for one year, the Trustee and the Paying Agent will pay the money back
to the Company at its request. After that, all liability of the Trustee and such
Paying Agent with respect to such money will cease.

         11.      DEFEASANCE PRIOR TO REDEMPTION OR MATURITY.

         Subject to certain conditions contained in the Indenture, the Company
at any time may terminate some or all of its obligations under the Notes and the
Indenture if the Company deposits with the Trustee money or Government
Securities sufficient to pay the principal of, premium, and interest on, the
Notes to redemption or maturity, as the case may be.

         12.      AMENDMENT, SUPPLEMENT AND WAIVER.

         Subject to certain exceptions, the Indenture or the Notes may be
amended or supplemented with the consent of the Holders of at least a majority
in principal amount of the Notes then outstanding, and any existing Default or
Event or Default or compliance with any provision of the Indenture or the Notes
may be waived with the consent of the Holders of a majority in principal amount
of the then outstanding Notes. Without the consent of any Holder of a Note, the
Indenture or the Notes may be amended or supplemented to cure any ambiguity,
defect or inconsistency, to provide for uncertificated Notes in addition to or
in place of Certificated Notes, to provide for the assumption of the Company's
obligations to Holders of Notes in case of a merger or consolidation, to make
any change that would provide any additional rights or benefits to the Holders
of the Notes or that does not adversely affect the legal rights under the
Indenture of any such Holder, or to comply with the requirements of the SEC in
order to effect or maintain the qualification of the Indenture under the TIA as
then in effect.

         13.      DEFAULTS AND REMEDIES.

         An "Event of Default" occurs if one of the following shall have
occurred and be continuing:

         (a)    the Company defaults in the payment when due of any interest
payable with respect to the Notes at any time, which default continues for a
period of 30 calendar days;

         (b)    the Company defaults in payment when due of the principal of or
premium, if any, on the Notes at maturity, upon repurchase (including, without
limitation, pursuant to a Change of Control Offer or an Asset Sale Offer), upon
acceleration, redemption or otherwise;

         (c)    the granting by the Company or any Restricted Subsidiary of any
Lien to secure Indebtedness in excess of US$100,000 (other than a Permitted
Lien);

         (d)    the Company fails to comply with the provisions of Sections
4.10, 4.14, 4.19 or 5.1 of the Indenture;

         (e)    the Company fails to comply with any of its other agreements in
this Indenture or the Notes and such failure continues for 30 calendar days
after notice from the Trustee or Holders of at least 25% in aggregate principal
amount of the Notes then outstanding;

         (f)    the Company defaults under any mortgage, indenture or instrument
under which there may be issued or by which there may be secured or evidenced
any Indebtedness for money borrowed of the Company or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists or
is created after the Effective Date, which default (i) is caused by a failure to
pay principal of or premium, if any, or interest on such Indebtedness following
the expiration of the grace period provided in such Indebtedness on the date of
such default (a "Payment Default") or (ii) results in the acceleration of such
Indebtedness prior to its express maturity and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other

                                       4
<PAGE>

such Indebtedness under which there has been a Payment Default or the maturity
of which has been so accelerated, aggregates US$5,000,000 (or the equivalent
thereof at time of determination) or more;

         (g)    the Company or any of its Restricted Subsidiaries fails to pay
final non-appealable judgments rendered against the Company or any of its
Restricted Subsidiaries aggregating in excess of US$2,500,000 (or the equivalent
thereof at time of determination), which judgments are not paid, discharged or
stayed for a period of 60 calendar days after such judgments become final and
non-appealable;

         (h)    the Company or any Restricted Subsidiary of the Company pursuant
to or within the meaning of any Bankruptcy Law: (i) commences a voluntary case
or proceeding, (ii) consents to the entry of an order for relief against it in
an involuntary case or proceeding, (iii) consents to the appointment of a
Custodian of it or for all or substantially all of its property, (iv) makes a
general assignment for the benefit of its creditors, (v) admits in writing its
inability to pay its debts generally as they become due or (vi) takes any
comparable action under any foreign laws relating to insolvency;

         (i)    a court of competent jurisdiction enters an order or decree
under any Bankruptcy Law that: (i) is for relief against the Company or any
Significant Subsidiary of the Company in an involuntary case or proceeding, (ii)
appoints a Custodian of the Company or any Significant Subsidiary of the Company
or for all or substantially all of its respective properties, or (iii) orders
the liquidation of the Company or any Significant Subsidiary of the Company, or
any similar relief is granted under any foreign laws, and in each case the order
or decree remains unstayed and in effect for 60 calendar days;

         (j)    (a) a default in the observance or performance of any covenant
or agreement contained in any Security Document which default continues for 20
calendar days after notice has been given to the Company by the Trustee or the
holders of at least 25% in principal amount of the outstanding Notes, or (b) for
any reason other than the satisfaction in full and discharge of all obligations
secured thereby or any action or inaction of the Trustee or the Holders after
receiving notice of the requirement to take any such action from the Company,
any of the Security Documents ceases to be in full force and effect (other than
in accordance with its respective terms), or any of the Security Documents
ceases to give the Trustee the Liens, rights, powers and privileges purported to
be created thereby, or any Security Document is declared null and void, or the
Company or any of its Restricted Subsidiaries denies any of its obligations
under any Security Document, in each case with respect to Collateral the
aggregate value of which is in excess of US$100,000, or the Collateral becomes
subject to one or more Liens other than Permitted Liens securing one or more
obligations in excess of US$100,000 in the aggregate; or

         (k)    any Guarantee is declared null and void or ceases to be in full
force and effect (except as permitted under this Indenture) or any Guarantor
shall deny or disaffirm its obligations under its Guarantee.

         Notwithstanding the foregoing, if an Event of Default specified in
clause (f) above occurs and is continuing, such Event of Default and all
consequences thereof (including, without limitation, any acceleration or
resulting payment default) will be annulled and rescinded, automatically and
without any action by the Trustee or the Holders of the Notes, if (i) the
Indebtedness that is the subject of such Event of Default has been repaid, or
(ii) the default relating to such Indebtedness is waived or cured (and if such
Indebtedness has been accelerated, when the holders thereof have rescinded their
declaration of acceleration in respect of such Indebtedness).

         In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Notes pursuant to the
optional redemption provisions of this Indenture, an equivalent premium will
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Notes.

         If any Event of Default (other than an Event of Default specified in
clause (h) or (i) above occurs and is continuing), then the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes by
written notice to the Company and the Trustee may declare the unpaid principal
of, and any accrued interest on, all the Notes to be due and payable
immediately. If any Event of Default with respect to the Company specified in
clause (h) or (i) hereof occurs with respect to the Company, any Significant
Subsidiary of the Company or any group of Restricted Subsidiaries of the Company

                                       5

<PAGE>

that, taken together, would constitute a Significant Subsidiary of the Company,
all outstanding principal and interest on the Notes will be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder. The Holders of a majority in principal amount of the Notes then
outstanding, by written notice to the Trustee and to the Company, may rescind an
acceleration (except an acceleration due to a default in payment of the
principal of, or premium or interest on, any of the Notes) if the rescission
would not conflict with any judgment or decree and if all existing Events of
Default (except nonpayment of principal, premium, interest that have become due
solely because of the acceleration) have been cured or waived.

         Subject to the preceding paragraph, if an Event of Default occurs and
is continuing, the Trustee may pursue any available remedy by proceeding at law
or in equity to collect any payment due, or to enforce the performance of any
provision, under the Notes, this Indenture or the Security Documents. The
Trustee may refuse to enforce the Indenture or the Notes unless it receives
indemnity or security reasonably satisfactory to it. Holders of Notes may not
enforce the Indenture or the Notes except as provided in the Indenture. Subject
to certain limitations, Holders of a majority in principal amount of the Notes
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of
Default (except under clauses (a) or (b) above) if it determines that
withholding notice is in their interest.

         14.      INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in the event that the Trustee acquires any conflicting
interest (as such term is defined in TIA Section 310(b)), it must eliminate such
conflict within 90 calendar days, apply to the SEC for permission to continue as
trustee (to the extent permitted under TIA Section 310(b)) or resign. Any Agent
may do the same with like rights and duties.

         15.      NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND
OTHERS.

         No past, present or future director, officer, employee, incorporator,
partner or stockholder of either of the Company or any of its Subsidiaries, as
such, will have any liability for any obligations of the Company or its
Subsidiaries under the Notes, the Security Documents, the Guarantees or the
Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. Each Holder of a Note by accepting a Note waives
and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes and the Guarantees.

         16.      AUTHENTICATION.

         This Note will not be valid until authenticated by the manual signature
of the Trustee or an authenticating agent.

         17.      ABBREVIATIONS.

         Customary abbreviations may be used in the name of a Holder or an
assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the
entireties), JT TEN (= joint tenants with right of survivorship and not as
tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors
Act).

         18.      CUSIP NUMBERS.

         Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Notes and the Trustee may use CUSIP numbers in notices of
redemption as a convenience to Holders. No representation is made as to the
accuracy of such numbers either as printed on the Notes or as contained in any
notice of redemption and reliance may be placed only on the other identification
numbers placed thereon.

pursuant to which all payments received by such Grantor from its customers in
respect of all Accounts of such Grantor will, immediately upon receipt by such
Grantor (subject to its banks' policies regarding the availability of deposited
funds), be transferred to a specified Concentration Account of such Grantor.
Each Grantor covenants and agrees to cause all amounts received by such Grantor
in respect of its Accounts to be transferred to such Concentration Account
immediately upon receipt thereof.

the continuation of an Event of Default, the Grantors will deliver to the
Collateral Agent a revised, updated SCHEDULE 2 listing all Accounts (including
all Accounts owed by pay television customers) existing on such date in such
detail as the Collateral Agent or the Majority Holders might reasonably require.

            (f) Such Grantor will notify the Collateral Agent immediately if it
knows that any application or registration relating to any material Intellectual
Property may become forfeited, abandoned or dedicated to the public, or of any
adverse determination or development (including, without limitation, the

                                       23

<PAGE>

institution of, or any such determination or development in, any proceeding in
INPI, the United States Patent and Trademark Office, the United States Copyright
Office or any court or tribunal in any country) regarding such Grantor's
ownership of, or the validity of, any material Intellectual Property or such
Grantor's right to register the same or to own and maintain the same.

            (g) Whenever such Grantor, either by itself or through any agent,
employee, licensee or designee, shall file an application for the registration
of any Intellectual Property with INPI, the United States Patent and Trademark
Office, the United States Copyright Office or any similar office or agency in
any other country or any political subdivision thereof, such Grantor shall
report such filing to the Collateral Agent within five Business Days after the

Collateral Agent or the Majority Holders, such Grantor shall execute and
deliver, and have recorded, any and all agreements, instruments, documents, and
papers as the Collateral Agent or the Majority Holders may reasonably request to
evidence the Collateral Agent's security interest in any Copyright, Patent or
Trademark and the goodwill and general intangibles of such Grantor relating

            (h) Such Grantor will take all reasonable and necessary steps,
including, without limitation, in any proceeding before INPI, the United States
Patent and Trademark Office, the United States Copyright Office or any similar
office or agency in any other country or any political subdivision thereof, to
maintain and pursue each application (and to obtain the relevant registration)
and to maintain each registration of the Intellectual Property which is material
to the business of such Grantor, including, without limitation, filing of
applications for renewal, affidavits of use and affidavits of incontestability.

            (i) In the event that any Intellectual Property which is material to
the business of such Grantor is infringed, misappropriated or diluted by a third
party, such Grantor shall (i) take such actions as such Grantor shall reasonably
deem appropriate under the circumstances to protect such Intellectual Property
and (ii) if such Intellectual Property is of material economic value, promptly
notify the Collateral Agent after it learns thereof and take such action as such
Grantor deems appropriate to remedy such infringement, misappropriation or
dilution, to seek injunctive relief where appropriate and to recover any and all
damages for such infringement, misappropriation or dilution.

            4.10 VEHICLES. With respect to any Vehicle acquired by such Grantor
subsequent to the date hereof which has a book value or Fair Market Value equal

to take such action as the Collateral Agent or the Majority Holders may from
time to time reasonably require in order to protect or preserve its interests in
respect of the Authorization Rights;

            (b) In the event the Collateral Agent delivers to the Company the
notice referred to in Section 2.2(a) requiring the Authorization Rights to be
included in the Collateral, such Grantor shall deliver to ANATEL a request for
each required Authorization of the pledge of the Authorization Rights created
herein, such request being in form and substance reasonably satisfactory to the
Collateral Agent and the Majority Holders;

            (c) Such Grantor shall not, without the prior written consent of the
Majority Holders, grant or permit to exist any assignment, sale or transfer of,
or Lien over or in connection with, any of the Authorization Rights, except
pursuant to this Agreement;

            (d) Such Grantor shall not, without the prior written consent of the
Majority Holders, vary, amend, modify or terminate any Authorization Rights
Agreement in any respect which could reasonably be expected to have a material
adverse effect on the value of any Authorization Rights or the ability or
capacity of such Grantor to perform its obligations hereunder, except to the
extent required by ANATEL pursuant to the exercise of its authority under
Applicable Law;

            (e) Such Grantor shall not, without the prior written consent of the
Majority Holders, consent to any act or omission by ANATEL or any
instrumentality thereof which would constitute a material breach under any
Authorization Rights Agreement, to the extent that any such act or omission
could reasonably be expected to have a material adverse effect on the value of
any Authorization Rights or the ability or capacity of such Grantor to perform
its obligations hereunder; and

            (f) Such Grantor shall not, without giving prior written notice to
the Collateral Agent and the Trustee: (i) release ANATEL from any material
obligation under, or waive any material breach by ANATEL of, any Authorization

establish with a bank located in Brazil satisfactory to the Majority Holders
(collectively, the "COLLATERAL ACCOUNT BANK") a cash collateral account
(collectively, the "COLLATERAL ACCOUNT"), in the name of such Grantor, and
(except as provided in paragraph (b) below) under the joint control of the
Collateral Agent and such Grantor, into which there shall be deposited (i) the
Net Proceeds (consisting of cash and Cash Equivalents) received in respect of
any Collateral sold by such Grantor pursuant to an Asset Sale, (ii) any
Insurance Proceeds or Condemnation Proceeds, as the case may be, resulting from
a Loss Event suffered by such Grantor, required to be delivered to the
Collateral Agent pursuant to Section 4.10 of the Indenture and (iii) any
Proceeds of the Collateral transferred from the Concentration Account of such
Grantor after the issuance of a Default Notice in accordance with the provisions

                                       25

<PAGE>

of Section 4.15. Any income received with respect to the balance from time to
time standing to the credit of any Collateral Account, including any interest,
shall remain, or be deposited, in such Collateral Account. All right, title and
interest in and to the cash amounts on deposit from time to time in each
Collateral Account shall constitute part of the Collateral hereunder but shall
not constitute payment of the Secured Obligations until applied thereto as
hereinafter provided.

            (b) The balance from time to time standing to the credit of each
Collateral Account shall be subject to withdrawal only pursuant to written
instructions to the Collateral Account Bank signed by both the Collateral Agent
acting upon the instructions of the Majority Holders and the applicable Grantor,
which together shall have dominion and control over such account; PROVIDED that,
after the occurrence and during the continuation of any Event of Default, the
Collateral Agent shall have sole dominion and control over such account, and
requests for withdrawals therefrom will require only the signature of the
Collateral Agent acting upon the instructions of the Majority Holders. The
balance from time to time standing to the credit of each Collateral Account
shall be applied in the manner specified in paragraph (c) below.

            (c) The Net Proceeds (consisting of cash and Cash Equivalents)
received in respect of any Collateral sold pursuant to an Asset Sale, and any
Insurance Proceeds or Condemnation Proceeds, as the case may be, resulting from
a Loss Event shall be applied only in the manner and for the purposes described
in Section 4.10(b) of the Indenture. In connection with any request by any
Grantor to use proceeds on deposit in any Collateral Account, the Company or
other applicable Grantor shall deliver to the Collateral Agent, not less than
ten (10) Business Days prior to the intended use of such proceeds, an officer's
certificate signed by the chief executive officer, chief financial officer or
treasurer of the Company or of such other Grantor, describing the transaction or
transactions in which such proceeds are intended to be applied and certifying
that such use is permitted under the Indenture. Upon receipt of a certificate
complying with the foregoing, and provided no Default shall have occurred and be
continuing, the Collateral Agent and the applicable Grantor will, pursuant to
their joint written instructions given to the Collateral Account Bank, cause to
be withdrawn from the Collateral Account and paid to the applicable Grantor or
for its account in accordance with such Grantor's instructions the proceeds to
be so applied.

            (d) Cash on deposit in each Collateral Account shall be invested in
Cash Equivalents from time to time in accordance with the applicable Grantor's
written instructions; PROVIDED that, if an Event of Default shall have occurred
and be continuing, such instructions shall be given by the Collateral Agent
acting upon the instructions of the Majority Holders.

            (e) The procedures relating to the administration of each Collateral
Account will be set forth in greater detail in an agreement or agreements to be
entered into as soon as practicable after the Effective Date among the
applicable Grantor, the applicable Collateral Account Bank and the Collateral
Agent in form reasonably satisfactory to such parties which is consistent in all
material respects with the provisions of this Section 4.12.

            4.13 REGISTRATION. Within 20 days after the execution hereof, this
Agreement shall be registered by the applicable Grantors with the competent
Registry of Titles and Deeds for each city listed on Schedule 18 at the expense
of the Grantors, all in accordance with Article 130 of Law 6.015 of December 31,
1973.

            4.14 AFTER-ACQUIRED PROPERTY. The Grantors will amend the Schedules
hereto from time to time as provided in this Section to include any additional
assets or property acquired after the Effective Date. With respect to SCHEDULE
2, such update shall be made monthly as of the last Business Day of each month
beginning after the date the Company is first required to provide a revised,
updated SCHEDULE 2 to the Collateral Agent pursuant to Section 4.8(b). With
respect to SCHEDULES 4, 5, 6, 7, 8, 9, 10, 11, 12 13, 14 AND 15, such updates
shall be made quarterly as of the last Business Day of each calendar quarter
beginning after the Effective Date. With respect to SCHEDULE 3, such update
shall be made quarterly as of the last Business Day of each calendar quarter
beginning after the date the Collateral Agent notifies the Company pursuant to
Section 2.2(a) that the Authorization Rights are required to be included in the
Collateral. The Company will deliver to the Collateral Agent each updated
Schedule within ten (10) days after the monthly or quarterly date as of which
such Schedule is required to be updated and will cause the same, along with any
other required documents, to be registered with the relevant Registry of Title
and Deeds within ten (10) days after such delivery date in order to perfect the
security interest in such additional Collateral in favor of the Collateral
Agent, for the ratable benefit of the Secured Parties, and will provide evidence
of such registration to the Collateral Agent and the Trustee promptly
thereafter. Nothing herein will limit the Collateral Agent's right to require
the Company to provide more frequent updates of the Schedules if the Collateral
Agent reasonably determines that its security interests are unperfected with
respect to a material portion of the Collateral.

            4.15 CERTAIN MATTERS RELATING TO ACCOUNTS. (a) The Collateral Agent
and the Majority Holders shall have the right to make such test verifications of
the Accounts as they may reasonably consider advisable, and each Grantor shall
furnish all such assistance and information as the Collateral Agent or the
Majority Holders may reasonably require in connection with such test
verifications. At any time and from time to time, upon the Collateral Agent's
request and at the expense of the relevant Grantor, such Grantor shall furnish
to the Collateral Agent and the Secured Parties reports showing reconciliations,
aging and test verifications of, and trial balances for, the Accounts.

            (b) As soon as practicable after the Effective Date, each Grantor
will enter into a Concentration Account Agreement with the Collateral Agent and
a Concentration Account Bank and will cause all amounts received by it from its
customers or otherwise in respect of its Accounts to be paid into or transferred
to the specified Concentration Account at such Concentration Account Bank as
provided in Section 4.8 and the Concentration Account Agreement. So long as no
Event of Default has occurred and is continuing, the applicable Grantor will
have the right of withdrawal from its respective Concentration Account and will
be entitled to give all instructions to its respective Concentration Account
Bank regarding the operation of such Concentration Account and use of the funds
therein so long as such use and operation comply with the terms of the Indenture
and the Concentration Account Agreement. If an Event of Default occurs and is

                                       27

<PAGE>

continuing, upon the instructions of the Majority Holders, the Collateral Agent
will issue a Default Notice to each Concentration Account Bank and thereby
assume dominion and control over each Concentration Account. Each Grantor agrees
that, if a Default Notice is issued, the Collateral Agent alone shall have the
power of withdrawal from each Concentration Account and acknowledges that, while
such Default Notice is in effect, the Grantors shall not have any right, title
or interest in the Concentration Accounts or the amounts at any time appearing
to the credit of the Concentration Accounts. Each Concentration Account Bank
shall agree, after the issuance of a Default Notice, to remit all proceeds of
such payments deposited in the Concentration Accounts directly to the Collateral
Agent for deposit into the Collateral Account of the applicable Grantor or as
the Collateral Agent, acting upon the instructions of the Majority Holders, may
otherwise instruct such Concentration Account Bank. All such payments made to
the Collateral Agent shall be deposited in the Collateral Account of the
applicable Grantor or in such other account as the Collateral Agent, acting upon
the instructions of the Majority Holders, may otherwise designate. Each
Concentration Account Agreement will provide for delivery by the applicable
Grantor of powers of attorney in favor of representatives of the Collateral
Agent to permit the Collateral Agent to exercise dominion and control over each
Concentration Account upon the issuance of a Default Notice under the applicable
Concentration Account Agreement.

            (c) During the continuance of an Event of Default, at the Collateral
Agent's request, each Grantor shall deliver to the Collateral Agent, or provide
the Collateral Agent with access to, all original and other documents
evidencing, and relating to, the agreements and transactions which gave rise to
the Accounts, including, without limitation, all original orders, invoices and
shipping receipts.

            (d) Upon written notice given by the Collateral Agent to each
Concentration Account Bank to the effect that all Events of Default have ceased,
been cured or been waived, each Grantor's respective rights to give all
instructions regarding the operation of the Concentration Accounts and the use
of the funds therein will be reinstated.

            4.16 VISITATION RIGHTS. The Collateral Agent (and after the
occurrence and during the continuation of an Event of Default, any other Secured
Party), or any agents or representatives thereof (or of the other Secured
Parties after the occurrence and during the continuation of an Event of
Default), will have the right at any time during normal business hours and, if
an Event of Default has not occurred and is not continuing, upon prior notice to
the Company, to examine and make copies of and abstracts from the records and
books of account of, and visit the properties of, the Grantors, and to discuss
the affairs, finances and accounts of the Grantors with any of their officers or
directors and with their independent certified public accountants.

            4.17 COMMUNICATIONS WITH OBLIGORS; GRANTORS REMAIN LIABLE. (a) The
Collateral Agent in its own name or in the name of the Secured Parties may at
any time after the occurrence and during the continuance of a Default
communicate with obligors under the Accounts to verify with them to the
Collateral Agent's satisfaction the existence, amount and terms of any Accounts.

                                       28

<PAGE>

            (b) Anything herein to the contrary notwithstanding, each Grantor
shall remain liable under each of the Accounts to observe and perform all the
conditions and obligations to be observed and performed by it thereunder, all in
accordance with the terms of any agreement giving rise thereto. Neither the
Collateral Agent nor any Secured Party shall have any obligation or liability
under any Account (or any agreement giving rise thereto) by reason of or arising
out of this Agreement or the receipt by the Collateral Agent or any Secured
Party of any payment relating thereto, nor shall the Collateral Agent or any
Secured Party be obligated in any manner to perform any of the obligations of
any Grantor under or pursuant to any Account (or any agreement giving rise
thereto), to make any payment, to make any inquiry as to the nature or the
sufficiency of any payment received by it or as to the sufficiency of any
performance by any party thereunder, to present or file any claim, to take any
action to enforce any performance or to collect the payment of any amounts which
may have been assigned to it or to which it may be entitled at any time or
times.

                         SECTION 5. REMEDIAL PROVISIONS

            5.1 PLEDGED STOCK. (a) Unless an Event of Default shall have
occurred and be continuing and the Collateral Agent shall have given notice to
the relevant Grantor of the Collateral Agent's intent to exercise its
corresponding rights pursuant to paragraph (b) below, the Grantor shall be
permitted to receive all cash dividends and other distributions paid in respect
of the Pledged Stock and all payments and other distributions made in respect of
the Pledged Notes, in each case paid in the normal course of business of the
relevant Restricted Subsidiary and consistent with past practice, to the extent
permitted in the Indenture, and to exercise all voting and corporate rights with
respect to the Pledged Stock; PROVIDED, HOWEVER, that no vote shall be cast or
corporate right exercised or other action taken which, in the Collateral Agent's
reasonable judgment, would materially impair the Collateral or which would be
inconsistent with or result in any material violation of any provision of this
Agreement.

            (b) If an Event of Default shall occur and be continuing and the
Collateral Agent shall give notice of its intent to exercise such rights to the
relevant Grantor or Grantors, (i) the Collateral Agent shall have the right to
receive any and all cash dividends, payments or other Proceeds paid in respect
of the Investment Property and make application thereof to the Secured
Obligations in accordance with the terms of Section 5.7 hereof, and (ii) the
Collateral Agent shall have the right to require that any or all of the
Investment Property shall be registered in the name of the Collateral Agent or
its nominee, and the Collateral Agent or its nominee may thereafter exercise (x)
all voting, corporate and other rights pertaining to such Investment Property at
any meeting of shareholders of the relevant Restricted Subsidiary or otherwise
and (y) any and all rights of conversion, exchange and subscription and any
other rights, privileges or options pertaining to such Investment Property as if
it were the absolute owner thereof (including, without limitation, the right to
exchange at its discretion any and all of the Investment Property upon the
merger, consolidation, reorganization, recapitalization or other fundamental
change in the corporate structure of any Restricted Subsidiary, or upon the
exercise by the Company or the Collateral Agent of any right, privilege or
option pertaining to such Investment Property, and in connection therewith, the

                                       29

<PAGE>

right to deposit and deliver any and all of the Investment Property with any
committee, depositary, transfer agent, registrar or other designated agency upon
such terms and conditions as the Collateral Agent may determine), all without
liability except to account for property actually received by it, but the
Collateral Agent shall have no duty to any Person to exercise any such right,
privilege or option and shall not be responsible for any failure to do so or
delay in so doing.

            (c) Upon the occurrence and during the continuation of an Event of
Default, the Collateral Agent, for the ratable benefit of the Secured Parties,
shall have the right to exercise all the rights and powers conferred by articles
774, III of the Brazilian Civil Code, and may sell or cause to be sold all or
any part of the Investment Property at public auction or private sale, at the
best price obtainable by the Collateral Agent or its duly-appointed agent or
assignee, as applicable, in good faith and exercising the same degree of
diligence as a prudent owner would do, all in accordance with Section 5.5 below,
and otherwise subject to Applicable Law.

            (d) The Grantors hereby authorize and instruct each Restricted
Subsidiary which has issued any Investment Property pledged by any Grantor
hereunder to (i) comply with any instruction received by it from the Collateral
Agent in writing that (x) states that an Event of Default or a Default has
occurred and is continuing and (y) is otherwise in accordance with the terms of
this Agreement, without any other or further instructions from any Grantor, and
each Grantor agrees that each such Restricted Subsidiary shall be fully
protected in so complying, and (ii) after receipt of notice from the Collateral
Agent that an Event of Default has occurred and is continuing, pay any dividends
or other payments with respect to the Investment Property directly to the
Collateral Agent.

            5.2 NET PROCEEDS TO BE TURNED OVER TO COLLATERAL AGENT. In addition
to the rights of the Collateral Agent specified in Section 4.15 with respect to
payments of Accounts, if an Event of Default shall occur and be continuing, all
Proceeds received by any Grantor consisting of cash, checks and other near-cash
items shall be held by such Grantor in trust for the Collateral Agent, for the
ratable benefit of the Secured Parties, segregated from other funds of such
Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to
the Collateral Agent in the exact form received by such Grantor (duly indorsed
by such Grantor to the Collateral Agent, if required). All Proceeds received by
the Collateral Agent hereunder shall be held by the Collateral Agent in the
Collateral Account. All Proceeds while held by the Collateral Agent in the
Collateral Account (or by a Grantor in trust for the Collateral Agent) shall
continue to be held as collateral security for all the Secured Obligations and
shall not constitute payment thereof until applied as provided in Section 5.3.

            5.3 APPLICATION OF PROCEEDS. If an Event of Default shall have
occurred and be continuing, upon its receipt of instructions from the Majority
Holders, the Collateral Agent may apply all or any part of Proceeds held in the
Collateral Account or any Concentration Account in payment of the Secured
Obligations in accordance with Section 5.7 and any part of such funds which are
not applied and not required as collateral security for the Secured Obligations
shall, upon request, be paid over from time to time by the Collateral Agent to
the Company or other applicable Grantor or to whomsoever may be lawfully
entitled to receive the same. Any balance of such Proceeds remaining after the

                                       30

<PAGE>

Secured Obligations shall have been paid in full shall be paid over to the
Company or other applicable Grantor or to whomsoever may be lawfully entitled to
receive the same.

            5.4 AUTHORIZATION RIGHTS. If an Event of Default shall have occurred
and be continuing, each Grantor shall cause all amounts payable to it from time
to time under or in respect of its Authorization Rights to be paid directly to
the Collateral Account. Each Grantor agrees that, if for any reason it receives
any such amount in any other manner or place, such amount shall be forthwith
deposited by such Grantor into the Collateral Account.

            5.5 CODE AND OTHER REMEDIES. If an Event of Default shall occur and
be continuing, the Collateral Agent, on behalf of the Secured Parties, may
exercise, in addition to all other rights and remedies granted to them in this
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Secured Obligations, all rights and remedies of a secured party
under Brazilian law or any other Applicable Law. Without limiting the generality
of the foregoing, the Collateral Agent, without demand of performance or other
demand, presentment, protest, advertisement or notice of any kind (except any
notice required by law referred to below) to or upon any Grantor or any other
Person (all and each of which demands, defenses, advertisements and notices are
hereby waived), may in such circumstances forthwith collect, receive,
appropriate and realize upon the Collateral, or any part thereof, and/or may
forthwith sell, lease, assign, give option or options to purchase, or otherwise
dispose of and deliver the Collateral or any part thereof (or contract to do any
of the foregoing), in one or more parcels at public or private sale or sales, at
any exchange, broker's board or office of the Collateral Agent, or elsewhere
upon such terms and conditions as it may deem advisable and at such prices as it
may deem best, for cash or on credit or for future delivery without assumption
of any credit risk. The Collateral Agent or any Secured Party shall have the
right upon any such public sale or sales, and, to the extent permitted by law,
upon any such private sale or sales, to purchase the whole or any part of the
Collateral so sold, free of any right or equity of redemption in any Grantor,
which right or equity is hereby waived and released. Each Grantor further
agrees, at the Collateral Agent's request, to assemble the Collateral and make
it available to the Collateral Agent at places which the Collateral Agent shall
reasonably select, whether at such Grantor's premises or elsewhere. The
Collateral Agent shall apply the Net Proceeds of any action taken by it pursuant
to this Section 5.5, after deducting all reasonable costs and expenses of every
kind incurred in connection therewith or incidental to the care or safekeeping
of any of the Collateral or in any way relating to the Collateral or the rights
of the Collateral Agent and the Secured Parties hereunder, including, without
limitation, reasonable attorneys' fees and disbursements, to the payment in
whole or in part of the Secured Obligations in accordance with Section 5.7, and
only after such application and after the payment by the Collateral Agent of any
other amount required by any provision of law, need the Collateral Agent account
for the surplus, if any, to any Grantor. To the extent permitted by applicable
law, each Grantor waives all claims, damages and demands it may acquire against
the Collateral Agent or any Secured Party arising out of the exercise by them of
any rights hereunder. Notice of a proposed sale or other disposition of
Collateral shall be given to each Grantor at least ten (10) Business Days before
such sale or other disposition. Such notice, (a) in case of public sale, shall
state the time and place fixed for such sale, (b) in the case of sale at a
broker's board or on a securities exchange, shall state the board or exchange at
which such sale is to be made and the day on which the Collateral, or portion

                                       31

<PAGE>

thereof, will first be offered for sale at such board or exchange, and (c) in
the case of private sale, shall state the principal terms of the proposed
private sale (including price, payment terms and proposed purchaser). Any such
public sale shall be held at such time or times during ordinary business hours
and at such place or places as the Collateral Agent or its assignee may fix in
the notice of such sale. At any such public or private sale, the Collateral, or
portion thereof, to be sold may be sold in one lot as an entirety or in separate
parcels, as the Collateral Agent or its assignee may determine. The Collateral
Agent or its assignee shall not be obligated to make any sale of Collateral if
it shall determine not to do so or if it shall not have been so instructed by
the Majority Holders, regardless of the fact that notice of sale may have been
given.

            5.6 SALE OF PLEDGED STOCK. (a) The Grantors recognize that the
Collateral Agent may be unable to effect a public sale of any or all the Pledged
Stock, by reason of certain prohibitions contained in Law 6.385 of December 7,
1976, as amended, and complementary legislation and that the Collateral Agent
may be compelled to resort to one or more private sales thereof to a restricted
group of purchasers which will be obliged to agree, among other things, to
acquire such securities for their own account for investment and not with a view
to the distribution or resale thereof. The Grantors acknowledge and agree that
any such private sale may result in prices and other terms less favorable than
if such sale were a public sale and, notwithstanding such circumstances, agree
that any such private sale shall be deemed to have been made in a commercially
reasonable manner. The Collateral Agent shall be under no obligation to delay a
sale of any of the Pledged Stock for the period of time necessary to permit the
relevant Restricted Subsidiary to register such securities for public sale under
Law 6.385 of December 7, 1976, as amended, and complementary legislation, or
under other applicable securities laws, even if such Restricted Subsidiary would
agree to do so.

            (b) Each Grantor agrees to use its best efforts to do or cause to be
done all such other acts as may be necessary to make such sale or sales of all
or any portion of the Pledged Stock pursuant to the exercise by the Collateral
Agent of its rights hereunder valid and binding and in compliance with any and
all other Applicable Law. Each Grantor further agrees that a breach of the
foregoing covenant will cause irreparable injury to the Collateral Agent and the
Secured Parties, that the Collateral Agent and the Secured Parties have no
adequate remedy at law in respect of such breach and, as a consequence, that the
foregoing covenant shall be specifically enforceable against such Grantor, and
such Grantor hereby waives and agrees not to assert any defenses against an
action for specific performance of such covenant except for a defense that no
Event of Default or Default has occurred under the Indenture.

            5.7 APPLICATION OF PROCEEDS. All proceeds (including without
limitation all Proceeds of the Collateral) received by the Collateral Agent or
any Secured Party hereunder or under any other Security Document, the Indenture,
the Senior Notes or otherwise in connection with the exercise of remedies under
any of the foregoing, shall be applied to the Secured Obligations in the
following order of priority:

            (1)   FIRST, to pay fees and expenses of the Collateral Agent
                  pursuant to Section 7.4 or otherwise;

                                       32

<PAGE>

            (2)   SECOND, to pay fees and expenses of the Trustee pursuant to
                  Section 7.4 and other amounts payable to the Trustee under
                  Section 7.7 of the Indenture;

            (3)   THIRD, to pay fees and expenses of the holders of the
                  Senior Notes pursuant to Section 7.4;

            (4)   FOURTH, to pay accrued interest on the Senior Notes;

            (5)   FIFTH, to pay principal of the Senior Notes;

            (6)   SIXTH, to pay any remaining Secured Obligations; and

            (7)   SEVENTH, the balance, if any, to the applicable Grantor.

            5.8 WAIVER; DEFICIENCY. Each Grantor shall remain liable for any
deficiency if the proceeds of any sale or other disposition of the Collateral
are insufficient to pay the Secured Obligations and the reasonable fees and
disbursements of any attorneys employed by the Collateral Agent or the Secured
Parties to collect such deficiency.

                         SECTION 6. THE COLLATERAL AGENT

            6.1 COLLATERAL AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT, ETC. (a)
Each Grantor hereby irrevocably constitutes and appoints the Collateral Agent
and any officer or agent thereof, with full power of substitution, as its true
and lawful attorney-in-fact with full irrevocable power and authority in the
place and stead of such Grantor and in the name of such Grantor or in its own
name, for the purpose of carrying out the terms of this Agreement, to take any
and all appropriate action and to execute any and all documents and instruments
which may be necessary or desirable to accomplish the purposes of this Agreement
and which such Grantor has failed to take or exercise when required hereunder,
and, without limiting the generality of the foregoing, each Grantor hereby gives
the Collateral Agent the power and right, on behalf of such Grantor, without
notice to or assent by such Grantor, to do any or all of the following during
the continuance of an Event of Default:

            (i) in the name of such Grantor or its own name, or otherwise, take
      possession of and indorse and collect any checks, drafts, notes,
      acceptances or other instruments for the payment of moneys due under any
      Account or with respect to any other Collateral and file any claim or take
      any other action or proceeding in any court of law or equity or otherwise
      deemed appropriate by the Collateral Agent for the purpose of collecting
      any and all such moneys due under any Account or with respect to any other
      Collateral whenever payable;

                                       33

<PAGE>

            (ii) in the case of any Intellectual Property, execute and deliver,
      and have recorded, any and all agreements, instruments, documents and
      papers as the Collateral Agent may request to evidence the Collateral
      Agent's and the Secured Parties' security interest in such Intellectual
      Property and the goodwill and general intangibles of such Grantor relating
      thereto or represented thereby;

            (iii) pay or discharge taxes and Liens levied or placed on or
      threatened against the Collateral, effect any repairs or any insurance
      called for by the terms of this Agreement and pay all or any part of the
      premiums therefor and the costs thereof;

            (iv) execute, in connection with any sale provided for in Section
      5.5 or 5.6, any indorsements, assignments or other instruments of
      conveyance or transfer with respect to the Collateral; and

            (v) (1) direct any party liable for any payment under any of the
      Collateral to make payment of any and all moneys due or to become due
      thereunder directly to the Collateral Agent or as the Collateral Agent
      shall direct; (2) ask or demand for, collect, and receive payment of and
      receipt for, any and all moneys, claims and other amounts due or to become
      due at any time in respect of or arising out of any Collateral; (3) sign
      and indorse any invoices, freight or express bills, bills of lading,
      storage or warehouse receipts, drafts against debtors, assignments,
      verifications, notices and other documents in connection with any of the
      Collateral; (4) commence and prosecute any suits, actions or proceedings
      at law or in equity in any court of competent jurisdiction to collect the
      Collateral or any portion thereof and to enforce any other right in
      respect of any Collateral; (5) defend any suit, action or proceeding
      brought against such Grantor with respect to any Collateral; (6) settle,
      compromise or adjust any such suit, action or proceeding and, in
      connection therewith, give such discharges or releases as the Collateral
      Agent may deem appropriate; (7) assign any Copyright, Patent or Trademark
      (along with the goodwill of the business to which any such Copyright,
      Patent or Trademark pertains), throughout the world for such term or
      terms, on such conditions, and in such manner, as the Collateral Agent
      shall in its sole discretion determine; and (8) generally, sell, transfer,
      pledge and make any agreement with respect to or otherwise deal with any
      of the Collateral as fully and completely as though the Collateral Agent
      were the absolute owner thereof for all purposes, and do, at the
      Collateral Agent's option and such Grantor's expense, at any time, or from
      time to time, all acts and things which the Collateral Agent deems
      necessary to protect, preserve or realize upon the Collateral and the
      Collateral Agent's, and the Secured Parties' security interests therein
      and to effect the intent of this Agreement, all as fully and effectively
      as such Grantor might do.

            (vi) For the purposes of any Investment Property, to perform all
      necessary acts and to execute and deliver any instrument before any
      Authority, including, without limitation, CVM and ANATEL, and any stock
      exchange in case of public sale, and to execute all documents required for
      the transfer and assignment of any Investment Property sold.

                                       34

<PAGE>

            (vii) For purposes of any Authorization Rights, to represent such
      Grantor before any third party or Authority, to act, and to sign any
      agreement, instrument or document, in the name of and on behalf of such
      Grantor in order to give effect to the security interests created pursuant
      to this Agreement, if, within fifteen (15) days after notice from the
      Collateral Agent or the Majority Holders, such Grantor fails to do so.

            Anything in this Section 6.1(a) to the contrary notwithstanding, the
Collateral Agent agrees that it will not exercise any rights under the power of
attorney provided for in this Section 6.1(a) unless an Event of Default or
Default shall have occurred and be continuing.

            (b) If any Grantor fails to perform or comply with any of its
agreements contained herein, the Collateral Agent, at its option, but without
any obligation so to do, may perform or comply, or otherwise cause performance
or compliance, with such agreement.

            (c) The expenses of the Collateral Agent incurred in connection with
actions undertaken as provided in this Section 6.1, together with interest
thereon at a rate per annum equal to 13% (thirteen percent), from the date of
payment by the Collateral Agent to the date reimbursed by the relevant Grantor,
shall be payable by such Grantor to the Collateral Agent on demand.

            (d) All powers, authorizations and agencies contained in this
Agreement are coupled with an interest and are irrevocable until this Agreement
is terminated and the security interests created hereby are released.

            6.2 DUTY OF COLLATERAL AGENT. The Collateral Agent's sole duty with
respect to the custody, safekeeping and physical preservation of the Collateral
in its possession, shall be to deal with it in the same manner as the Collateral
Agent deals with similar property for its own account. The Collateral Agent and
the Secured Parties and any of their respective officers, directors, employees
or agents shall not be liable for failure to demand, collect or realize upon any
of the Collateral or for any delay in doing so or shall be under any obligation
to sell or otherwise dispose of any Collateral upon the request of any Grantor
or any other Person or to take any other action whatsoever with regard to the
Collateral or any part thereof. The powers conferred on the Collateral Agent and
the Secured Parties hereunder are solely to protect the Collateral Agent's and
the Secured Parties' interests in the Collateral and shall not impose any duty
upon the Collateral Agent or any Secured Party to exercise any such powers. The
Collateral Agent and the Secured Parties shall be accountable only for amounts
that they actually receive as a result of the exercise of such powers, and
neither they nor any of their officers, directors, employees or agents shall be
responsible to any Grantor for any act or failure to act hereunder, except for
their own or their employees', agents' directors' or assigns' gross negligence
or willful misconduct.

            6.3 FILINGS AND RECORDINGS FOR PERFECTION OF SECURITY Interests. To
the extent permitted by Applicable Law, each Grantor authorizes the Collateral
Agent (or any sub-agent duly appointed by it) to file or record with the
relevant Authority in Brazil and to make other filings or recordings of
documents or instruments with respect to the Collateral without the signature of

                                       35

<PAGE>

such Grantor in such form and in such offices as the Collateral Agent determines
appropriate to perfect the security interests of the Collateral Agent under this
Agreement. Anything herein to the contrary notwithstanding, in no event shall
the Collateral Agent be liable or responsible for compliance with any amendments
or changes to Brazilian law in the absence of specific instruction received by
it from the Majority Holders as to any required actions necessary in order to
comply therewith.

            6.4 AUTHORITY OF COLLATERAL AGENT. Each Grantor acknowledges that
the rights and responsibilities of the Collateral Agent under this Agreement
with respect to any action taken by the Collateral Agent or the exercise or
non-exercise by the Collateral Agent of any option, voting right, request,
judgment or other right or remedy provided for herein or resulting from or
arising out of this Agreement shall, as among the Collateral Agent, the Secured
Parties and the Grantors, be governed by the Collateral Agency Agreement and by
such other agreements with respect thereto as may exist from time to time among
them, but, as among the Collateral Agent and the Grantors, the Collateral Agent
shall be conclusively presumed to be acting as agent for the ratable benefit of
the Secured Parties, with full and valid authority so to act or refrain from
acting, and no Grantor shall be under any obligation, or entitlement, to make
any inquiry respecting such authority.

                            SECTION 7. MISCELLANEOUS

            7.1 AMENDMENTS IN WRITING. None of the terms or provisions of this
Agreement may be waived, amended, supplemented or otherwise modified except by a
written instrument executed by each affected Grantor and the Collateral Agent,
PROVIDED that any provision of this Agreement imposing obligations on any
Grantor may be waived by the Collateral Agent in a written instrument executed
by the Collateral Agent.

            7.2 NOTICES. All notices, requests and demands to or upon the
Collateral Agent or any Grantor hereunder shall be addressed at its notice
address set forth on SCHEDULE 1.

            7.3 NO WAIVER BY COURSE OF CONDUCT; CUMULATIVE REMEDIES. Neither the
Collateral Agent nor any Secured Party shall by any act (except by a written
instrument pursuant to Section 7.1), delay, indulgence, omission or otherwise be
deemed to have waived any right or remedy hereunder or to have acquiesced in any
Default or Event of Default. No failure to exercise, nor any delay in
exercising, on the part of the Collateral Agent or any Secured Party, any right,
power or privilege hereunder shall operate as a waiver thereof. No single or
partial exercise of any right, power or privilege hereunder shall preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. A waiver by the Collateral Agent or any Secured Party of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Collateral Agent or such Secured Party would otherwise
have on any future occasion. The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of any
other rights or remedies provided by law.

                                       36

<PAGE>

            7.4 ENFORCEMENT EXPENSES; INDEMNIFICATION. (a) Each Grantor agrees
to pay or reimburse the Collateral Agent and each Secured Party for all their
costs and expenses incurred in collecting against such Grantor in enforcing or
preserving any rights under this Agreement and the other Security Documents to
which such Grantor is a party, including, without limitation, the reasonable
fees and disbursements of counsel (including the allocated fees and expenses of
in-house counsel) to the Collateral Agent and the Secured Parties, respectively.

            (b) Each Grantor agrees to pay, and to save the Collateral Agent and
the Secured Parties harmless from, any and all liabilities with respect to, or
resulting from any delay in paying, any and all stamp, excise, sales or other
taxes which may be payable or determined to be payable with respect to any of
the Collateral or in connection with any of the transactions contemplated by
this Agreement.

            (c) Each Grantor agrees to pay, and to save the Collateral Agent
harmless from, any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration of this Agreement to the extent the Company and
the Guarantors would be required to do so pursuant to the Indenture, except for
amounts arising as a result of the gross negligence or willful misconduct of the
Collateral Agent, or its agents, employees, directors or assigns.

            (d) Each Grantor agrees to pay, and to save the Secured Parties
harmless from, any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration of this Agreement to the extent the Company and
the Guarantors would be required to do so pursuant to the Indenture, except for
amounts arising as a result of the gross negligence or willful misconduct of the
Secured Parties, or their agents, employees, directors or assigns.

            (e) The agreements in this Section 7.4 shall survive repayment of
the Secured Obligations and all other amounts payable under the Indenture, and
the other Security Documents.

            7.5 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
successors and assigns of each Grantor and shall inure to the benefit of the
Collateral Agent, the Secured Parties and their successors and assigns; PROVIDED
that no Grantor may assign, transfer or delegate any of its rights or
obligations under this Agreement without the prior written consent of the
Collateral Agent and the Majority Holders.

            7.6 SET-OFF. (a) Each Grantor hereby irrevocably authorizes the
Collateral Agent and the Secured Parties at any time and from time to time while
an Event of Default or Default shall have occurred and be continuing, without
notice to such Grantor or any other Grantor, any such notice being expressly
waived by each Grantor, to set-off and appropriate and apply any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or

                                       37

<PAGE>

unmatured, at any time held or owing by the Collateral Agent or any Secured
Party to or for the credit or the account of such Grantor, or any part thereof
in such amounts as the Collateral Agent or such Secured Party may elect, against
and on account of the obligations and liabilities of such Grantor to the
Collateral Agent or such Secured Party hereunder and claims of every nature and
description of the Collateral Agent or such Secured Party against such Grantor,
in any currency, whether arising hereunder, under the Indenture, the Senior
Notes, any other Security Document or otherwise, as the Collateral Agent or such
Secured Party may elect, whether or not the Collateral Agent or such Secured
Party has made any demand for payment and although such obligations, liabilities
and claims may be contingent or unmatured. The Collateral Agent and each Secured
Party shall notify such Grantor promptly of any such set-off and the application
made by the Collateral Agent or such Secured Party of the proceeds thereof. The
rights of the Collateral Agent and each Secured Party under this Section 7.6 are
in addition to other rights and remedies (including, without limitation, other
rights of set-off) which the Collateral Agent or such Secured Party may have.

            (b) If any Secured Party (a "benefitted Secured Party") at any time
shall receive any payment of all or part of its Secured Obligations, or receive
any collateral in respect thereof (whether voluntarily or involuntarily, by
set-off pursuant to paragraph (a) above or otherwise), in a greater proportion
than any such payment to or collateral received by any other Secured Party, if
any, in respect of such other Secured Party's Secured Obligations, such
benefitted Secured Party shall purchase for cash from the other Secured Parties
such portion of such other Secured Party's Secured Obligations, or shall provide
such other Secured Parties with the benefits of any such collateral, or the
proceeds thereof, as shall be necessary to cause such benefitted Secured Party
to share the excess payment or benefits of such collateral or proceeds ratably
with each of the other Secured Parties; and if after taking into account such
sharing the benefitted Secured Party continues to have access to additional
funds of or collateral granted by the Grantors for application on account of the
Secured Obligations, then the benefitted Secured Party shall use such funds or
collateral to reduce indebtedness of the Company held by it and share such
payments and the benefits of the collateral with the other Secured Parties;
PROVIDED, HOWEVER, that if all or any portion of such excess payment or benefits
is thereafter recovered from such benefitted Secured Party, such purchase shall
be rescinded, and the purchase price and benefits returned, to the extent of
such recovery, but without interest. The Grantors agree that each Secured Party
so purchasing a portion of another Secured Party's Secured Obligations may
exercise all rights of payment (including, without limitation, rights of
set-off) with respect to such portion as fully as if such Secured Party were the
direct holder of such portion.

            7.7 COUNTERPARTS. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts (including
by telecopy), and all of said counterparts taken together shall be deemed to
constitute one and the same instrument.

            7.8 SEVERABILITY. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

            7.9  SECTION HEADINGS.  The Section headings used in this
Agreement are for convenience of reference only and are not to affect the
construction hereof or be taken into consideration in the interpretation
hereof.

            7.10 INTEGRATION. This Agreement, the Indenture, the Mortgage and
the Collateral Agency Agreement represent the entire agreement of the Grantors,
the Collateral Agent and the Secured Parties with respect to the subject matter
hereof and thereof, and there are no promises, undertakings, representations or
warranties by the Collateral Agent or any Secured Party relative to subject
matter hereof and thereof not expressly set forth or referred to herein or in

            7.11 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND

HOWEVER, THAT ALL PROVISIONS REGARDING THE RIGHTS, DUTIES AND OBLIGATIONS OF THE
COLLATERAL AGENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED
ENTIRELY WITHIN SUCH STATE.

            7.12  SUBMISSION TO JURISDICTION; WAIVERS.  Each Grantor hereby
irrevocably and unconditionally:

            (a) submits for itself and its property in any legal action or
proceeding relating to this Agreement, or for recognition and enforcement of any
judgment in respect thereof, to the non-exclusive general jurisdiction of the
courts sitting in Brasilia, Distrito Federal, S_o Paulo, State of S_o Paulo, and
Rio de Janeiro, State of Rio de Janeiro;

            (b) consents that any such action or proceeding may be brought in
such courts and waives any objection that it may now or hereafter have to the
venue of any such action or proceeding in any such court or that such action or
proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

            (c) agrees that service of process in any such action or proceeding
may be effected by mailing a copy thereof by registered or certified mail (or
any substantially similar form of mail), postage prepaid, to such Grantor at its
address referred to in Section 7.2 or at such other address of which the

stated to survive such termination) of the Collateral Agent and each Grantor
