                    ON              , 1997, UNLESS EXTENDED.
                             ---------------------
 
    Paging Network do Brasil S.A., a Brazilian corporation (the "Company"),
hereby offers, upon the terms and subject to the conditions set forth in this
Prospectus and the accompanying Letter of Transmittal (which together constitute
the "Exchange Offer"), to exchange an aggregate principal amount of up to
US$125,000,000 of its 13 1/2% Senior Notes due 2005 (the "New Notes"), which
have been registered under the Securities Act of 1933 (the "Securities Act"),
pursuant to a Registration Statement (as defined herein) of which this
Prospectus constitutes a part, for a like principal amount of its outstanding
13 1/2% Senior Notes due 2005 (the "Old Notes"), of which US$125,000,000
aggregate principal amount is outstanding.
 
    The terms of the New Notes are identical in all material respects to the
terms of the Old Notes, except for certain transfer restrictions and
registration rights relating to the Old Notes and except that, if the Exchange
Offer is not consummated by November 3, 1997, the interest rate borne by the Old
Notes will increase by 0.50% per annum for the first 90-day period following
November 3, 1997 and will increase by an additional 0.50% per annum with respect
to each subsequent 90-day period up to a maximum amount of 2.00% per annum until
the Exchange Offer is consummated. The New Notes are being offered hereunder in
order to satisfy certain obligations of the Company under the Purchase Agreement
dated as of May 30, 1997 (the "Purchase Agreement") among the Company, Paging
Brazil Holding Co., LLC ("Holding LLC") and the initial purchasers of the Old
Notes (the "Initial Purchasers") and the Notes Registration Rights Agreement
dated June 6, 1997 (the "Notes Registration Rights Agreement") among the Company
and the Initial Purchasers. The New Notes evidence the same debt as the Old
Notes and will be issued under and entitled to the same benefits under the
Indenture (as defined herein). In addition, the New Notes and the Old Notes will
be treated as one series of securities under the Indenture. The New Notes and
the Old Notes are collectively referred to herein as the "Notes." See
"Description of the Notes."
 
    Interest on the Notes of 13 1/2% per annum is payable semiannually in cash
in U.S. dollars in arrears on June 6 and December 6 of each year, commencing
December 6, 1997. The Notes will mature on June 6, 2005. At the closing of the
offering of the Old Notes, the Company used a portion of the net proceeds to
purchase a portfolio consisting of U.S. Government Securities (as defined
herein), representing funds sufficient to make the first six payments of
interest (exclusive of any Additional Amounts (as defined herein) or Additional
Interest (as defined herein) which may become payable) on the Notes, with any
balance to be retained by the Company. These securities were pledged as security
for the benefit of holders of the Notes. See "Description of the Notes--Escrow
Account." Payments under the Notes will be made in U.S. dollars free and clear
of, and without withholding or deduction for, any taxes imposed by Brazil to the
extent provided herein. See "Description of the Notes."
 
    The Notes will be redeemable at the option of the Company, in whole or in
part, at any time on or after June 6, 2001 at the redemption prices set forth
herein, plus accrued and unpaid interest, if any, thereon to the applicable
redemption date. Notwithstanding the foregoing, on or prior to June 6, 2000, the
Company may, at its option, use the net proceeds of one or more Significant
Equity Offerings (as defined herein) yielding gross cash proceeds of not less
than US$35.0 million to redeem up to an aggregate of 35% of the principal amount
of the Notes originally issued from the holders of Notes on a pro rata basis (or
as nearly pro rata as practicable), at a redemption price of 113 1/2% of the
principal amount thereof, plus accrued and unpaid interest to the date of
redemption; PROVIDED that not less than US$81.25 million aggregate principal
amount of Notes would remain outstanding immediately after such redemption. In
addition, the Notes will be redeemable, in whole but not in part, at the option
of the Company at 100% of the principal amount thereof, plus accrued and unpaid
interest, if any, to the date of redemption, at any time prior to maturity in
the event of certain changes affecting the withholding tax treatment of the
Notes. Upon a Change of Control, each holder of Notes will have the right to
require the Company to purchase such holder's Notes at 101% of the principal
amount thereof, plus accrued and unpaid interest, if any, to the date of
purchase. In the event of a Change of Control, there can be no assurance that
the Company (i) will obtain necessary approval from the Brazilian Central Bank
to permit such purchase, in whole or in part, or (ii) will have available funds
sufficient to pay for all of the Notes that might be delivered by holders. See
"Description of the Notes."

    SEE "RISK FACTORS" BEGINNING ON PAGE 15 FOR A DISCUSSION OF CERTAIN FACTORS
THAT HOLDERS OF THE OLD NOTES SHOULD CONSIDER IN CONNECTION WITH THE EXCHANGE
OFFER AND THAT PROSPECTIVE INVESTORS IN THE NEW NOTES SHOULD CONSIDER IN
CONNECTION WITH SUCH INVESTMENT.
                             ---------------------
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
  AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
      ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
                        CONTRARY IS A CRIMINAL OFFENSE.
 
                  THE DATE OF THIS PROSPECTUS IS       , 1997

(COVER CONTINUED FROM PREVIOUS PAGE)
 
    The Notes will be senior unsecured obligations of the Company ranking PARI
PASSU in right of payment with all existing and future unsubordinated unsecured
indebtedness of the Company. As of March 31, 1997, after giving effect to the
Offering, the Company would have had no indebtedness ranking PARI PASSU with or
junior in right of payment to the Notes. In addition, there are currently no
subsidiaries of the Company.
 
    The Company is making the Exchange Offer in reliance on the position of the
staff of the Securities and Exchange Commission (the "Commission") as set forth
in certain no-action letters addressed to other parties in other transactions.
However, the Company has not sought its own no-action letter and there can be no
assurance that the staff of the Commission would make a similar determination
with respect to the Exchange Offer as in such other circumstances. Based upon
these interpretations by the staff of the commission, the Company believes that
New Notes issued pursuant to this Exchange Offer in exchange for Old Notes may
be offered for resale, resold and otherwise transferred by a holder thereof
other than (i) a broker-dealer who purchased such Old Notes directly from the
Company to resell pursuant to Rule 144A or any other available exemption under
the Securities Act or (ii) a person that is an "affiliate" (as defined in Rule
405 of the Securities Act) of the Company without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that such New Notes are acquired in the ordinary course of such holder's
business and that such holder is not participating, and has no arrangement or
understanding with any person to participate, in the distribution of such New
Notes. Holders of Old Notes accepting the Exchange Offer will represent to the
Company in the Letter of Transmittal that such conditions have been met. Any
holder who participates in the Exchange Offer for the purpose of participating
in a distribution of the New Notes may not rely on the position of the staff of
the Commission as set forth in these no-action letters and would have to comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with any secondary resale transaction. A secondary resale
transaction in the United States by a holder who is using the Exchange Offer to
participate in the distribution of New Notes must be covered by a registration
statement containing the selling securityholder information required by Item 507
of Regulation S-K of the Securities Act.
 
    Each broker-dealer (other than an "affiliate" of the Company) that receives
New Notes for its own account pursuant to the Exchange Offer must acknowledge
that it acquired the Old Notes as a result of market-making activities or other
trading activities and will deliver a prospectus in connection with any resale
of such New Notes. The Letter of Transmittal states that by so acknowledging and
by delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act. This Prospectus,
as it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of New Notes received in exchange for
Old Notes where such Old Notes were acquired by such broker-dealer as a result
of market-making activities or other trading activities. The Company has agreed
that, for a period of 180 days after the Expiration Date (as defined herein), it
will make this Prospectus available to any broker-dealer for use in connection
with any such resale. See "Plan of Distribution." Any broker-dealer who is an
affiliate of the Company may not rely on such no-action letters and must comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with any secondary resale transaction. See "The Exchange Offer."
 
    The New Notes are new securities for which there is currently no market. The
Company presently does not intend to apply for listing of the New Notes on any
securities exchange or for quotation through the National Association of
Securities Dealers Automated Quotation System ("NASDAQ"). The Company has been
advised by the Initial Purchasers, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, Goldman, Sachs & Co. and Bear, Stearns & Co. Inc. that, following
completion of the Exchange Offer, they presently intend to make a market in the
New Notes; however, the Initial Purchasers are not obligated to do so and any
market-making activities with respect to the New Notes may be discontinued at
any time without notice. There can be no assurance that an active public market
for the New Notes will develop.
 
    Any Old Notes not tendered and accepted in the Exchange Offer will remain
outstanding and will be entitled to all the rights and preferences and will be
subject to the limitations applicable thereto under the Indenture. Following
consummation of the Exchange Offer, the holders of Old Notes will continue to be
subject to the existing restrictions upon transfer thereof and the Company will
have no further obligation to such holders (other than the Initial Purchasers)
to provide for the registration under the Securities Act of the Old Notes held
by them. To the extent that Old Notes are tendered and accepted in the Exchange
Offer, a holder's ability to sell untendered Old Notes could be adversely
affected. It is not expected that an active market for the Old Notes will
develop while they are subject to restrictions on transfer.
 
    The Company will accept for exchange any and all Old Notes that are validly
tendered and not withdrawn on or prior to 5:00 p.m., New York City time, on the
date the Exchange Offer expires, which will be         , 1997 (the "Expiration
Date"), unless the Exchange Offer is extended by the Company in its sole
discretion, in which case the term "Expiration Date" shall mean the latest date
and time to which the Exchange Offer is extended. Tenders of Old Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration
Date. The Exchange Offer is not conditioned upon any minimum principal amount of
Old Notes being tendered for exchange. However, the Exchange Offer is subject to
certain conditions which may be waived by the Company and to the terms and
provisions of the Notes Registration Rights Agreement. Old Notes may be tendered
only in denominations of US$1,000 and integral multiples thereof. The Company
has agreed to pay the expenses of the Exchange Offer. See "The Exchange
Offer--Fees and Expenses." The New Notes will bear interest from the last
interest payment date of the Old Notes to occur prior to the issue date of the
New Notes or, if no such interest has been paid, from June 6, 1997. Holders of
the Old Notes whose Old Notes are accepted for exchange will not receive
interest on such Old Notes for any period subsequent to the last interest
payment date to occur prior to the issue date of the New Notes, if any, and will
be deemed to have waived the right to receive any interest payment on the Old
Notes accrued from and after such interest payment date or, if no such interest
has been paid, from June 6, 1997.
 
    This Prospectus, together with the Letter of Transmittal, is being sent to
all registered holders of Old Notes as of         , 1997.
 
    The Company will not receive any proceeds from this Exchange Offer. No
dealer-manager is being used in connection with this Exchange Offer. See "Use of
Proceeds" and "Plan of Distribution."

                      ENFORCEABILITY OF CIVIL LIABILITIES
 
    The Company is a Brazilian corporation with substantially all of its assets
and operations located, and substantially all of its revenues derived, outside
the United States. The Company has appointed CT Corporation System, New York,
New York, as its agent to receive service of process with respect to any action
brought against it in any federal or state court in the State of New York
arising from the offering of the Old Notes and the Exchange Offer. However, it
may not be possible for investors to enforce outside the United States judgments
against the Company obtained in the United States in any such actions, including
actions predicated upon the civil liability provisions of the United States
federal and state securities laws. In addition, all of the directors and
officers of the Company are residents of Brazil, and all or substantially all of
the assets of such persons are located outside the United States. As a result,
it may not be possible for investors to effect service of process within the
United States upon such persons, or to enforce against them judgments obtained
in United States courts, including judgments predicated upon the civil liability
provisions of the United States federal and state securities laws.
 
    The Company has been advised by its Brazilian counsel, Xavier, Bernardes,
Braganca, Sociedade de Advogados, that judgments of U.S. courts for civil
liabilities predicated upon the federal securities laws of the United States,
subject to certain requirements described below, may be enforced in Brazil. A
judgment against the persons described above or the Company obtained outside of
Brazil would be enforceable in Brazil against such persons or the Company
without reconsideration of the merits upon ratification of that judgment by the
Brazilian Federal Supreme Court. The ratification generally will occur if the
foreign judgment (a) fulfills all formalities required for its enforceability
under the laws of the country where the foreign judgment is granted, (b) is
issued following personal service of process on the Company or the persons
described above, or on a properly appointed agent for service of process, (c) is
issued by a competent court after proper service of process, (d) is not subject
to appeal, (e) is authenticated by a Brazilian consular office in the country
where the foreign judgment is issued and is accompanied by a sworn translation
into Portuguese and (f) is not contrary to Brazilian law, national sovereignty
or public policy or "good morals" (as set forth in Brazilian law) and does not
contain any provision which is or would for any reason not be upheld by the
courts of Brazil. Notwithstanding the foregoing, no assurance can be given that
ratification would be obtained, that the process described above can be
conducted in a timely manner or that a Brazilian court would enforce a monetary
judgment for violation of the United States securities laws with respect to the
Notes. The Company has been further advised by its Brazilian counsel that
original actions predicated on the federal securities laws of the United States
may be brought in Brazilian courts and that Brazilian courts may enforce civil
liabilities in such actions against the Company, its directors and certain of
its officers named herein. A plaintiff (whether Brazilian or non-Brazilian) who
resides outside Brazil during the course of litigation in Brazil must provide a
bond to guarantee court costs and legal fees if the plaintiff owns no real
property in Brazil.

COMPANY OVERVIEW
 
    PageNet do Brasil's objective is to become a leading provider of paging and
wireless messaging services in Brazil. The Company has secured licenses which
enable it to broadcast paging services throughout the country, and currently
serves approximately 3,500 subscribers. The Company has installed 44 paging
transmitters in 10 cities (the "Existing Coverage Area"), commenced offering
paging services in greater Sao Paulo in January 1997, and plans to begin
marketing paging services in greater Rio de Janeiro in the first quarter of 1998
and in three additional cities in the first quarter of 1999. PageNet do Brasil
was formed by Paging Network International N.V. ("PageNet NV"), a wholly owned
subsidiary of Paging Network, Inc. ("PageNet"), the largest paging company in
the United States, Warburg, Pincus Ventures, L.P. ("Warburg Pincus"), a private
equity fund, TVA Sistema de Televisao S.A. ("TVA"), a leading pay television
company in Brazil, and a wholly owned subsidiary of Abril S.A., Latin America's
largest publishing enterprise, IVP Paging (Cayman) L.P. ("IVP Cayman"), the
general partner of which is IVP-- International Venture Partners, Inc. ("IVP"),
a private investment fund focused on Brazil, and Multiponto Telecomunicacoes
Ltda. ("Multiponto"), an equity investor focused on the Brazilian
telecommunications sector. Management believes that a number of factors create a
favorable environment for the paging industry in Brazil, including: (i) Brazil's
large population, (ii) its growing and stable economy, (iii) the paging market's
relatively low penetration rate and high historical growth rate, and (iv) the
relatively high demand for reliable communications services. The Company
believes it will be well positioned to be a leading provider of paging services
in Brazil because of its state-of-the-art infrastructure, high quality services,
low cost structure and strategic relationships.
 
    The Company has completed the buildout of the Sao Paulo system, installed
the infrastructure necessary to support its Sao Paulo operations and
substantially built out its paging system in Rio de Janeiro. The Company is
currently focused on Sao Paulo and Rio de Janeiro (the "Initial Markets") and
expects to offer paging services in Brasilia, Curitiba and Belo Horizonte (the
"Expansion Markets") by the first quarter of 1999. The Company currently offers
its Sao Paulo subscribers extended paging service in the other cities in the
Existing Coverage Area.
 
SUBSTANTIAL BUSINESS OPPORTUNITY
 
    Brazil is the largest country in Latin America, with a population of
approximately 158 million people. Although the paging industry began in Brazil
in the 1960s, it remains largely underdeveloped, fragmented and
undercapitalized. The Company estimates that, as of December 1996, there were
approximately 800,000 pagers in operation in Brazil (up from an estimated
400,000 in 1995 and 200,000 in 1994), representing a market penetration of less
than one-half of one percent of the population and an annual
 
                                       5
<PAGE>
growth rate of 100% since 1994. The one-half of one percent penetration rate in
Brazil is considerably lower than the United States rate of approximately 15%.
 
    Although Brazil's economy has strengthened significantly as a result of its
recent openness to direct foreign investment and its reduced inflation rate for
the past two years, the telecommunications industry is still underdeveloped. As
of December 1996, the approximately 13.5 million telephone lines in service in
Brazil corresponded to a penetration rate of only 8.7%, which places Brazil
among the least developed countries in the world for availability of basic
telephone service. The Company believes that a principal factor driving the
significant growth of paging services, and wireless communications generally, is
the demand for reliable, portable communications alternatives to Brazil's
underdeveloped telephone system.
 
    Management believes that paging is a particularly attractive and practical
method of communications. Generally, a pager is a highly reliable, portable and
economical communications alternative to cellular telephone service and often
complements cellular telephone service due to its longer battery life and better
building penetration which allows subscribers to receive pages when cellular
service is not available. Additionally, paging service increases communications
with mobile employees and facilitates call management by allowing the subscriber
to act on messages at the subscriber's convenience. Moreover, in Brazil,
alphanumeric pagers are an alternative to traditional telephone service in the
home, for which the waiting list to obtain ordinary telephone lines from the
local service providers is approximately one to three years and, for many
Brazilians, is prohibitively expensive. Also, the cost and speed of deploying a
paging system is relatively low on a per subscriber basis as compared to other
communications devices: (i) the transmitters and terminals have a lower cost
than certain other wireless communication systems; (ii) paging system capital
expenditures are required only for transmission facilities and the acquisition
of pagers for leasing to customers; and (iii) most costs associated with
increasing the capacity of a paging system and acquiring additional pagers for
lease may be incurred as customers are added to the system.
 
BUSINESS HIGHLIGHTS
 
    ATTRACTIVE LICENSE AREAS.  Pursuant to operating agreements with TVA,
Multiponto and an affiliate of IVP, the Company has secured the use of their
respective paging licenses. The Existing Coverage Area is comprised of the
following 10 cities: Sao Paulo, Rio de Janeiro, Brasilia, Curitiba, Belo
Horizonte, Porto Alegre, Salvador, Recife, Belem and Goiania. The cities of Sao
Paulo and Rio de Janeiro are the business centers of Brazil and encompass a
population of approximately 33 million and represent an estimated two-thirds of
the Brazilian paging market. The remaining eight cities have strong business
communities and their combined metropolitan areas encompassed an aggregate
population of approximately 18 million. Management believes that a significant
market of potential business customers has been neglected by the Company's
competitors and, as the Company enters each of its markets, it intends to
actively target such business customers.
 
    EQUITY SPONSORSHIP/STRATEGIC RELATIONSHIPS.  The Company's investors include
PageNet, Warburg Pincus, TVA, IVP and Multiponto. PageNet is the largest
provider of paging services in the United States, with approximately 9.5 million
pagers in service in the United States, more than the combined number of pagers
in service of the second and third largest U.S. providers of paging services.
PageNet has entered into an agreement (the "Technical Services Agreement") with
the Company which provides the Company with PageNet's products, intellectual
property (including the exclusive use of PageNet's tradename in Brazil), paging
expertise, volume discounts and other capabilities. In addition, certain of the
equity investors have extensive experience in the Brazilian communications
industry. At the closing of the offering of the Old Notes, Warburg Pincus, IVP
and Multiponto had provided approximately US$30 million of redeemable preferred
and common equity capital to the Company, and TVA, IVP and Multiponto had
secured paging licenses for the Company's use.
 
    EXPERIENCED MANAGEMENT TEAM.  The Company's senior management team, which
has been in place since the Company's inception, has extensive experience in the
development, growth and management of
 
                                       6
<PAGE>
paging and other businesses in the United States and Brazil. Additionally,
members of the Company's senior management team have experience in formulating
and implementing marketing strategies directed at business and consumer paging
customers. The Company's management team includes former senior managers of two
of PageNet's largest operations in the United States, former senior managers of
multinational corporations operating in Brazil and former senior managers of
Brazilian paging companies.
 
    STATE-OF-THE-ART PAGING NETWORK.  The Company has built a state-of-the-art,
satellite linked, FLEX-Registered Trademark- based paging network with 44
transmitters in the 10 cities comprising the Existing Coverage Area. Relative to
the systems of the Company's competitors, which use terrestrial communications
networks, the Company believes that its satellite-linked transmission systems
provide customers with more reliable receipt of pages. Moreover, rather than
relying on manufacturers or vendors, management has applied PageNet's expertise
to design and implement all aspects of the paging infrastructure buildout, from
transmitter site selection and transmitter installation alignment to satellite
linkage and the programming of the paging terminal. The Company has completed
the buildout of the Sao Paulo system where it introduced paging services in
January 1997. The Rio de Janeiro system buildout is substantially complete and
local operations are scheduled to commence there in the first quarter of 1998.
In addition to Sao Paulo and Rio de Janeiro, the Company has built transmitters
in eight other cities, and offers subscribers extended paging service in those
cities. The Company expects to launch local operations in the Expansion Markets
in the first quarter of 1999, and will evaluate, on an ongoing basis, the
opportunity for the introduction and provision of services in other markets.
 
    ADVANCED INFORMATION SYSTEMS.  The Company uses an advanced proprietary
management information system, customized for the Brazilian market. This system
is used primarily to support three principal areas of the Company's business:
(i) customer service, including billing systems; (ii) network management and
operational support systems; and (iii) general business support systems,
including financial management. The Company's information systems have been
designed to accommodate efficiently the increased volumes of data that the
Company expects to process in the future as the Company's subscriber base
continues to grow.
 
BUSINESS STRATEGY
 
    The Company's strategy is to become a leading provider of paging services in
Brazil. The principal elements of the Company's business strategy are to: (i)
provide high quality paging services at a low cost, (ii) leverage the PageNet
relationship, (iii) gain rapid market penetration, and (iv) provide superior
customer service.
 
    PROVIDE HIGH QUALITY PAGING SERVICES AT A LOW COST.  The Company has
employed state-of-the-art FLEX-Registered Trademark- technology developed by
Motorola, Inc. and is using equipment similar to that used by PageNet in the
United States. Furthermore, the Company utilizes a fully redundant paging system
that is linked by satellite. Management believes that as the number of
subscribers grows, this advanced technology will allow the Company to be a
provider of high quality paging services at a low cost per subscriber.
 
    LEVERAGE THE PAGENET RELATIONSHIP.  The Company is implementing a marketing
strategy and operating procedures similar to those of PageNet in the United
States, and several members of the Company's senior management have had
significant experience managing PageNet operations in the United States.
Moreover, pursuant to the Technical Services Agreement, PageNet provides the
Company with access to PageNet's products, paging expertise, intellectual
property (including the exclusive use of PageNet's tradename in Brazil), volume
supplier discounts and other capabilities. The Company also expects to benefit
from the favorable relationships that PageNet has established with suppliers of
paging equipment and from its use of the PageNet brand name, which is well
established among multinational corporations. PageNet do Brasil is PageNet's
first venture in the Latin American paging market, and PageNet's only enterprise
in Brazil. See "Business--Trademarks."
 
                                       7
<PAGE>
    GAIN RAPID MARKET PENETRATION.  The Company seeks to gain subscribers in its
markets rapidly through extensive marketing and advertising and competitive
pricing. Unlike competitors whose primary focus has been the consumer market,
the Company focuses on both business and consumer paging customers. The Company
targets business customers through a commissioned direct sales force and through
telemarketing, and will target individual customers through advertising and
through retail distribution channels including the use of "retail showrooms"
located strategically throughout the Company's markets.
 
    PROVIDE SUPERIOR CUSTOMER SERVICE.  Management believes that its competitors
have not made customer service a primary focus of their business strategy and do
not provide the customer with service standards that are prevalent in the United
States. By focusing on key elements of customer satisfaction during the sales
process and over the life of the subscriber, the Company will provide high
levels of customer service similar to those provided by PageNet in the United
States. Moreover, similar to PageNet's practice in the United States, the
Company is introducing customer service account representatives to the paging
industry in Brazil, as a complement to sales representatives. The primary
function of customer service account representatives is to serve existing
accounts. In addition, customer service account representatives act as a
secondary sales force, targeting existing customers for additional services and
paging units. The Company believes this innovation will allow it to ensure
superior customer satisfaction, thereby minimizing customer turnover and
increasing subscriber base growth.
 
FINANCING REQUIREMENTS
 
    The Company commenced the buildout of systems for its paging services in May
1996 and plans to substantially complete the buildout of the Initial Markets by
the first quarter of 1998 and the Expansion Markets by the first quarter of
1999. The Company expects that the available net proceeds from the sale of the
Old Notes, together with cash on hand, will be sufficient to complete the
planned buildout of the Initial Markets only and that it will need to secure
additional financing to complete the planned buildout of the Expansion Markets.
See "Use of Proceeds."
 
    The principal capital expenditure requirements to construct a paging system
involve the acquisition of pagers for leasing and the acquisition and
installation of transmission facilities, both of which are directly related to
the demand for paging service. Additional capital is required to fund operating
losses incurred during the initial stages of constructing and rolling out
services. The Company currently anticipates that its cash requirements
(comprised of capital expenditures, working capital requirements, debt service
requirements and anticipated operating losses) from inception in May 1996
through December 2000, will be approximately US$150 million, including
approximately US$100 million in capital expenditures, of which approximately
US$55 million is attributable to the purchase of pagers for leasing. The Company
estimates that, of the US$150 million, approximately US$80 million will be
required to fund the capital requirements for the Initial Markets through 2000.
The actual amounts required by the Company will vary based upon the timing and
success of the Company's rollout of services in its markets as well as the mix
between leased and purchased pagers. If demand for the Company's services is
less than expected, the Company should be able to reduce certain costs that are,
to a large extent, demand driven and/or delay the rollout of its services in the
Expansion Markets. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

                                      parties in other transactions. However, the Company
                                      has not sought its own no-action letter and there can
                                      be no assurance that the staff of the Commission
                                      would make a similar determination with respect to
                                      the Exchange Offer as in such other circumstances.
                                      Based on these interpretations by the staff of the
                                      Commission, the Company believes that New Notes
                                      issued pursuant to this Exchange Offer in exchange
                                      for Old Notes may be offered for resale, resold and
                                      otherwise transferred by a holder thereof other than
                                      (i) a broker-dealer who purchase such Old Notes
                                      directly from the Company to resell pursuant to Rule
                                      144A or any other available exemption under the
                                      Securities Act or (ii) a person that is an
                                      "affiliate" (as defined in Rule 405 of the Securities
                                      Act) of the Company without compliance with the
                                      registration and prospectus delivery provisions of
                                      the Securities Act, provided that such New Notes are
                                      acquired in the ordinary course of such holder's
                                      business and that such holder is not participating,
                                      and has no arrangement or understanding with any
                                      person to participate, in the distribution of such
                                      New Notes. Holders of Old Notes accepting the
                                      Exchange Offer will represent to the Company in the
                                      Letter of Transmittal that such conditions have been
                                      met. Any holder who participates in the Exchange
                                      Offer for the purpose of participating in a
                                      distribution of the New Notes may not rely on the
                                      position of the staff of the Commission as set forth
                                      in these no-action letters and would have to comply
                                      with the registration and prospectus delivery

                                      broker-dealer (other than an "affiliate" of the
                                      Company) that receives New Notes for its own account
                                      pursuant to the Exchange Offer must acknowledge that
                                      it acquired the Old Notes as the result of
                                      market-making activities or other trading activities
                                      and will deliver a prospectus in connection with any
                                      resale of such New Notes. The Letter of Transmittal
                                      states that by so acknowledging and by delivering a
                                      prospectus, a broker-dealer will not be deemed to

                                      of the Securities Act. This Prospectus, as it may be
                                      amended or supplemented from time to time, may be
                                      used by a broker-dealer in connection with resales of
                                      New Notes received in exchange for Old Notes where
                                      such Old Notes were acquired by such broker-dealer as
                                      a result of market-making activities or other trading
                                      activities. In addition, pursuant to Section 4(3)
                                      under the Securities Act, until            , 1997,

                                      whether or not participating in the Exchange Offer,
                                      may be required to deliver a Prospectus. The Company
                                      has agreed that, for a period of 180 days after the
                                      date of this Prospectus, it will make this Prospectus
                                      available to any broker-dealer for use in connection
                                      with any such resale. See "Plan of Distribution". Any
                                      broker-dealer who is an affiliate of the Company may
                                      not rely on such no-action letters and must comply

                                      preferences, and will be subject to the limitations,
                                      applicable thereto under the Indenture. All
                                      untendered and tendered but unaccepted Old Notes
                                      (collectively, the "Remaining Old Notes") will

                                      that the Company (i) will obtain necessary approval
                                      from the Brazilian Central Bank (the "Central Bank")
                                      to permit such purchase, in whole or in part, or (ii)

Withholding Taxes;
  Additional Amounts................  Under a temporary rate reduction from withholding tax
                                      under current Brazilian tax rules, interest in
                                      respect of the Notes during 1997 will not be subject
                                      to withholding tax. However, if the Notes are
                                      redeemed for any reason prior to the fifth year
                                      following their issuance, then the Company will be
                                      required to pay an additional withholding tax
                                      retroactively on interest, fees and commissions paid
                                      in connection with the Notes from the date of
                                      issuance through the date of such earlier redemption.
                                      Withholding taxes of up to 15% will be payable in
                                      respect of the Notes if the temporary rate reduction
                                      is not extended to years after 1997. The Company has
                                      agreed to pay such Additional Amounts as will result
                                      in receipt by the holders of Notes of such amounts as
                                      would have been received by them had no such
                                      withholding or deduction been required, except as set
                                      forth under "Description of the Notes--Additional
                                      Amounts." See "Tax Considerations."
 
Optional Redemption.................  The Notes will be redeemable at the option of the
                                      Company, in whole or in part, at any time on or after
                                      June 6, 2001 at the redemption prices set forth
                                      herein, plus accrued and unpaid interest, if any,
                                      thereon to the applicable redemption date.
                                      Notwithstanding the foregoing, on or prior to June 6,
                                      2000, the Company may, at its option, use the net
                                      proceeds of one or more Significant Equity Offerings
                                      yielding gross cash proceeds of not less than US$35.0
                                      million to redeem up to an aggregate of 35% of the
                                      principal amount of the Notes originally issued from
                                      the holders of Notes on a pro rata basis (or as
                                      nearly pro rata as practicable), at a redemption
                                      price of 113 1/2% of the principal amount thereof,
                                      plus accrued and unpaid interest to the date of
                                      redemption; PROVIDED that no less than US$81.25
                                      million aggregate principal amount of Notes would
                                      remain outstanding immediately after such redemption.
                                      See "Description of the Notes--Redemption."

Tax Redemption......................  In the event of certain changes affecting withholding
                                      taxes applicable to payments on the Notes, the Notes
                                      will be redeemable, in whole but not in part, at the
                                      option of the Company, at 100% of the principal
                                      amount thereof, plus accrued and unpaid interest, if
                                      any, to the date of redemption.
 
Asset Sale Offer....................  The Company will be required in certain circumstances
                                      to make an offer to purchase Notes with a portion of
                                      the net cash proceeds of certain asset sales at a
                                      purchase price equal to 100% of the principal amount
                                      thereof plus accrued interest, if any, to the date of
                                      purchase. See "Description of the Notes--Certain
                                      Covenants." The Company's ability to consummate such
                                      offer will be subject to prior approval from the
                                      Central Bank. See "Risk Factors--Risk Factors

Certain Covenants...................  The indenture under which the Old Notes were issued
                                      (the "Indenture") contains certain covenants that,
                                      among other things, limits the ability of the Company
                                      to (i) incur additional indebtedness or issue certain
                                      preferred stock, (ii) pay dividends or make
                                      distributions in respect of the capital stock of the
                                      Company or make certain other restricted payments,
                                      (iii) conduct a business other than a Permitted
                                      Business (as defined herein), (iv) create certain
                                      liens and (v) enter into certain transactions with
                                      affiliates or other interested persons. In addition,
                                      the Indenture limits the ability of the Company to
                                      consolidate, merge or sell all or substantially all
                                      of its assets. These covenants are subject to
                                      important exceptions and qualifications. See
                                      "Description of the Notes--Certain Covenants."

                                  RISK FACTORS
 
    BEFORE MAKING AN INVESTMENT DECISION, PROSPECTIVE PURCHASERS SHOULD CONSIDER
CAREFULLY, IN LIGHT OF THEIR OWN FINANCIAL CIRCUMSTANCES AND INVESTMENT
OBJECTIVES, ALL THE INFORMATION SET FORTH HEREIN AND, IN PARTICULAR, THE SPECIAL
FACTORS APPLICABLE TO AN INVESTMENT IN BRAZIL AND APPLICABLE TO AN INVESTMENT IN
THE COMPANY, INCLUDING THOSE SET FORTH BELOW. IN GENERAL, INVESTING IN THE
SECURITIES OF ISSUERS IN DEVELOPING COUNTRIES, SUCH AS BRAZIL, INVOLVES A HIGHER
DEGREE OF RISK THAN INVESTING IN THE SECURITIES OF ISSUERS IN THE UNITED STATES
AND CERTAIN OTHER JURISDICTIONS. A NUMBER OF THE MATTERS DISCUSSED IN THIS
PROSPECTUS ARE NOT HISTORICAL OR CURRENT FACTS BUT RATHER ADDRESS POTENTIAL
FUTURE CIRCUMSTANCES AND DEVELOPMENTS. THE DISCUSSION OF SUCH MATTERS AND
SUBJECT AREAS IS QUALIFIED BY THE RISKS AND UNCERTAINTIES SURROUNDING FUTURE
EXPECTATIONS GENERALLY, AND ALSO MAY MATERIALLY DIFFER FROM THE COMPANY'S ACTUAL
EXPERIENCE INVOLVING ANY ONE OF THE FUTURE MATTERS OR SUBJECT AREAS. THE COMPANY
HAS ATTEMPTED TO IDENTIFY CERTAIN OF THE FACTORS THAT IT CURRENTLY BELIEVES WILL
CAUSE ACTUAL EXPERIENCE TO DIFFER FROM ITS EXPECTATIONS, PARTICULARLY THOSE RISK
FACTORS SET FORTH BELOW; HOWEVER, THERE CAN BE NO ASSURANCE THAT OTHER RISKS AND
UNCERTAINTIES MAY NOT MATERIALLY ADVERSELY IMPACT THE COMPANY'S ABILITY TO MEET
ITS BUSINESS OBJECTIVES.
 
RISK FACTORS RELATING TO BRAZIL
 
    GENERAL.  Social, economic or political instability, among other
developments in Brazil, could adversely affect the financial condition and
results of operations of the Company, the ability of the Company to repay the
Notes. In the past, Brazil has suffered from high levels of inflation, low real
growth rates and political uncertainty. Brazil is generally considered by
investors to be an "emerging market" and thus political, economic, social or
other developments in other such markets may adversely affect the market value
and liquidity of the Notes. For example, in December 1994, the Mexican
government sharply devalued the PESO, resulting in an economic crisis in Mexico.
The Mexican PESO crisis adversely affected the market value and liquidity of
securities issued by companies in many of the "emerging markets," including
Brazil. There can be no assurance that events in other such markets will not
adversely affect the market value and liquidity of the Notes.
 
    ECONOMIC UNCERTAINTY; EFFECTS OF EXCHANGE RATE FLUCTUATIONS.  Brazil has
experienced extremely high rates of inflation for many years. Inflation, as
measured by the Getulio Vargas Foundation's General Index of Market Prices (the
"IGPM Index"), was approximately 458% in 1991, 1,175% in 1992, 2,567% in 1993,
870% in 1994, 15% in 1995 and was an estimated 10% in 1996. Inflation,
government actions to combat inflation and public speculation about future
actions have had significant negative effects on the Brazilian economy in
general and have also contributed materially to economic uncertainty in Brazil.
In periods of inflation, many of the Company's expenses will tend to increase.
Generally, in periods of inflation, a company is able to raise its prices to
offset the rise in its expenses and may set its prices without government
regulation. However, under Brazilian law designed to reduce inflation, the rates
which the Company may charge to a particular subscriber may not be increased
until the next anniversary of the subscriber's initial subscription date. Thus,
the Company is less able to offset expense increases with revenue increases.
Accordingly, inflation may have a material adverse effect on the Company's
results of operations and financial condition.
 
    Beginning in 1994, the Brazilian Government commenced the "Real Plan," an
economic stabilization plan designed to reduce inflation by, among other things,
reducing certain public expenditures, collecting debts owed to the Brazilian
Government, increasing tax revenues and continuing the privatization of certain
state-owned enterprises. On July 1, 1994, as part of the Real Plan, the
Brazilian Government introduced a new currency, the REAL. There can be no
assurance that the Real Plan will continue to be successful in controlling the
level of inflation, that future governmental actions will not trigger an
increase in inflation or that inflation will not have a material adverse effect
on the Company's results of operations and financial condition.
 
                                       15
<PAGE>
    Brazil's rate of inflation and the government's actions to combat inflation
have also affected the relationship of the value of Brazil's currency to the
value of the U.S. dollar. Historically, Brazil's currency frequently had been
devalued in relation to the U.S. dollar. However, after its introduction, the
REAL initially appreciated against the U.S. dollar. In an effort to address
concerns about the possible overvaluation of the REAL relative to the U.S.
dollar, and in light of the economic upheaval in Mexico that resulted from the
rapid devaluation of the Mexican PESO, the Brazilian government in March 1995
introduced new exchange rate policies which established a trading band for the
REAL against the U.S. dollar. From April 30, 1996 to April 30, 1997 the REAL
declined in value relative to the U.S. dollar by approximately 7.18%. There can
be no assurance that the REAL will not again be devalued relative to the U.S.
dollar, or that the REAL will not fluctuate significantly relative to the U.S.
dollar.
 
    Substantially all of the Company's revenues are expected to be denominated
in REAIS. A substantial portion of the Company's indebtedness, including the
Notes, may be expected to be denominated in U.S. dollars. In addition, certain
of the Company's operating expenses, including a significant portion of its
equipment costs and reimbursement obligations under the Technical Services
Agreement, are denominated in U.S. dollars. Any devaluation of the Brazilian
currency relative to any foreign currency in which debt or other obligations of
the Company are denominated could result in a foreign exchange loss with respect
to such indebtedness or obligations, if such devaluation were in excess of
inflation and the rate at which the Company raises prices. Any devaluation could
also force the Company to seek additional financing although the Company's
ability to obtain such financing may be impaired by such event. As a result, the
relationship of Brazil's currency to the value of the U.S. dollar and other
currencies, and the rates of devaluation of Brazil's currency relative to the
prevailing rates of inflation, may adversely affect the Company's financial
condition and results of operations, as well as its ability to meet its debt
service obligations (including payment of principal of, premium, if any, and
interest on the Notes) and operating expenses. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Inflation and
Exchange Rates." Moreover, if the Company cannot increase its prices to match
the rate of inflation, even if the rate of inflation matches the rate of
devaluation, the Company's ability to meet its debt service obligations and
operating expenses may be impaired.
 
    The Company may experience economic loss with respect to its investments and
fluctuations in its reported results of operations solely as a result of
currency rate fluctuations, which may have a material adverse effect on the
Company's financial condition. The Company intends to explore various
alternatives that may be available to hedge exchange rate risks, although there
can be no assurance that any such alternatives will be available on terms
acceptable to the Company.
 
    CONTROLS AND RESTRICTIONS ON U.S. DOLLAR REMITTANCES.  Brazilian law
provides that whenever there is a material imbalance, or a serious risk of a
material imbalance, in Brazil's balance of payments, the Brazilian Government
may, for a limited period of time, impose restrictions on the remittance to
foreign investors of the proceeds of their investments in Brazil, as it did for
approximately six months in 1989 and early 1990. The Brazilian Government may
also impose restrictions on the conversion of the Brazilian currency into
foreign currencies. Such restrictions may hinder or prevent the Company from
purchasing equipment required to be paid for in any currency other than REAIS,
paying scheduled interest and principal payments under the Notes in U.S. dollars
and making payment on judgments obtained in a court in Brazil. Such restrictions
could adversely affect the Company. The Company could also be adversely affected
by delays in, or a refusal to grant, any required Brazilian governmental
approval for conversion of REAL payments and remittances abroad in respect of
such dividends, distributions, interest and principal payments.
 
    The Brazilian Government currently restricts the ability of Brazilian or
foreign persons or entities to convert Brazilian currency into U.S. dollars or
other currencies other than in connection with certain authorized transactions.
The Central Bank has authorized the issuance of the Notes and, although there
can be no assurance, is expected, in due course to issue a certificate of
registration authorizing each of the scheduled payments of principal of, premium
on, and interest on the Notes or for payments of principal of,
 
                                       16
<PAGE>
premium on and interest on the Notes upon any early redemption of the Notes at
the option of a holder of Notes. However, consent from the Central Bank is
needed for the payment of principal of, premium, if any, on and interest on the
Notes upon acceleration of the Notes following an Event of Default. In addition,
consent from the Central Bank is needed for (i) payments in respect of the Notes
upon redemption by the Company in the event of certain changes in Brazilian law
relating to tax withholding, as described under "Description of the
Notes--Redemption--Redemption for Changes in Withholding Taxes," (ii) payments
in respect of the Notes in the event of redemption of the Notes by the Company,
as described under "Description of the Notes--Redemption--Optional Redemption by
the Company," (iii) payments in respect of the Notes in the event of an Asset
Sale Offer, as described under "Description of the Notes--Certain
Covenants--Disposition of Proceeds of Asset Sales," and (iv) payments in respect
of the Notes in the event of a Change of Control Offer, as described under
"Description of the Notes-- Redemption--Mandatory Redemption--Offers to Purchase
upon Change of Control and Certain Asset Sales." There can be no assurance that
any required consent from the Central Bank will be obtained.
 
    There can be no assurance that the Brazilian Government will not in the
future impose more restrictive foreign exchange regulations that would have the
effect of eliminating or restricting the Company's access to foreign currency
that would be required to meet its foreign currency obligations, including the
Notes. The likelihood of the imposition of such restrictions by the Brazilian
Government may be affected by, among other factors, the extent of Brazil's
foreign currency reserves, the availability of sufficient foreign currency on
the date a payment is due, the size of Brazil's debt service burden relative to
the economy as a whole, Brazil's policy toward the International Monetary Fund
and political constraints to which Brazil may be subject.
 
    POLITICAL UNCERTAINTY.  Historically, the Brazilian Government has often
changed monetary, credit, tariff and other policies to influence the course of
Brazil's economy. Such government actions have included wage and price controls
as well as other measures, such as freezing bank accounts, imposing capital
controls and inhibiting imports and exports. A primary objective of the
Brazilian Government in recent years has been to control government spending.
Some progress has been made, but fiscal deficits remain high. Reducing the
deficit is made more difficult by Brazil's Constitution, which requires the
Brazilian Government to make substantial funds available to the state
administrations, while limiting the Brazilian Government's ability to raise
sufficient funds from taxes. Changes in policy involving, among other things,
tariffs, exchange controls, regulatory policy and taxation, as well as events
such as inflation, devaluation, social instability or other political, economic
or diplomatic developments, could adversely affect the Brazilian economy and
have a material adverse effect on the Company's results of operations and
financial condition.
 
    The Brazilian political environment has been marked by high levels of
uncertainty since Brazil returned to civilian rule in 1985 after 20 years of
military government. The death of a President-elect in 1985 and the resignation
of another President in 1992 in the midst of his impeachment trial, as well as
frequent turnover at and immediately below the cabinet level, have contributed
to delays in the adoption of coherent and sustained policies to confront the
country's economic issues. Mr. Fernando Henrique Cardoso, Brazil's Finance
Minister at the time of implementation of the Real Plan, became President of
Brazil in January 1995. President Cardoso was elected by a coalition of
political parties and, as a result, his administration is required, from time to
time, to accept certain compromises. Even though the Brazilian Constitution
currently prohibits re-election of the President, presently a Constitutional
Amendment is being examined by the Brazilian Congress, which, if approved, will
make re-election possible. President Cardoso has supported the Real Plan, the
reduction of inflation, privatization measures and certain free-market policies;
however, the Real Plan has not been definitively approved by the Brazilian
Congress although the provisional measures which instituted the Real Plan have
been successively reenacted. There can be no assurance that any of the
administration's policies, including the Real Plan will be approved without
modifications by the legislature.
 
                                       17
<PAGE>
    ENFORCEABILITY OF JUDGMENTS.  The Company has been advised by its Brazilian
counsel, Xavier, Bernardes, Braganca, Sociedade de Advogados, that judgments for
monetary claims obtained in U.S. courts arising of or in relation to the
obligations of PageNet do Brasil in respect of the Indenture or the Notes will
be enforceable in Brazil without reconsideration of the merits upon ratification
by the Brazilian Federal Supreme Court. The ratification generally will occur if
the foreign judgment (a) fulfills all formalities required for its
enforceability under the laws of the country where the foreign judgment is
granted, (b) is issued following personal service of process on the Company or
on a properly appointed agent for service of process, (c) is issued by a
competent court after proper service of process, (d) is not subject to appeal,
(e) is authenticated by a Brazilian consular office in the country where the
foreign judgment is issued and is accompanied by a sworn translation into
Portuguese and (f) is not contrary to Brazilian law, national sovereignty or
public policy or "good morals" (as set forth in Brazilian law) and does not
contain any provision which is or would for any reason not be upheld by the
courts of Brazil. Notwithstanding the foregoing, no assurance can be given that
ratification would be obtained, that the process described above can be
conducted in a timely manner or that a Brazilian court would enforce such a
monetary judgment for violation of the United States securities laws with
respect to the Notes.
 
    Any judgment obtained against the Company in a court in Brazil in respect of
the Indenture or the Notes will be expressed in the Brazilian currency
equivalent of the U.S. dollar judgment amount at the commercial exchange rate on
the date on which such judgment is obtained, and such Brazilian currency amount
will be corrected in accordance with the exchange variation until the judgment
holder receives effective payment. See "Enforceability of Civil Liabilities."
 
RISK FACTORS RELATING TO THE COMPANY AND THE NOTES
 
    CONSEQUENCES OF FAILURE TO PROPERLY TENDER OLD NOTES PURSUANT TO THE
EXCHANGE OFFER.  Holders of Old Notes who do not exchange their Old Notes for
New Notes pursuant to the Exchange Offer will continue to be subject to the
following restrictions on transfer with respect to their Old Notes: (i) the
Remaining Old Notes may be resold only if registered pursuant to the Securities
Act, if any exemption from registration is available thereunder, or if neither
such registration nor such exemption is required by law, and (ii) the Remaining
Old Notes will bear a legend restricting transfer in the absence of registration
or an exemption therefrom. The Company does not currently anticipate that it
will register the Old Notes under the Securities Act. To the extent that Old
Notes are tendered and accepted in connection with the Exchange Offer, any
trading market for Remaining Old Notes could be adversely affected.
 
    Issuance of the New Notes in exchange for the Old Notes pursuant to the
Exchange Offer will be made only after timely receipt by the Exchange Agent of
such Old Notes, a properly completed and duly executed Letter of Transmittal and
all other required documents. Therefore, holders of the Old Notes desiring to
tender such Old Notes in exchange for New Notes should allow sufficient time to
ensure timely delivery. The Company is under no duty to give notification of
defects or irregularities with respect to tenders of Old Notes for exchange. Old
Notes that are not tendered or that are tendered but not accepted by the Company
for exchange, will, following consummation of the Exchange Offer, continue to be
subject to the existing restrictions upon transfer thereof under the Securities
Act and, upon consummation of the Exchange Offer, certain registration rights
under the Notes Registration Rights Agreement will terminate.
 
    LIMITED OPERATING HISTORY; FUTURE OPERATING LOSSES AND NEGATIVE CASH
FLOW.  The Company was recently formed and has only recently commenced
operations. Prospective investors, therefore, have no meaningful historical
financial or operating information about the Company upon which to base an
evaluation of an investment in the Notes. Businesses which are in their initial
stages of development present substantial business and financial risks and may
suffer significant losses. Such early stage businesses must develop business
relationships, establish operating procedures, hire staff and complete other
tasks appropriate for the conduct of their intended business activities. The
Company's prospects must be considered in light of
 
                                       18
<PAGE>
the uncertainties associated with the formation of a new business in a
developing market with limited comparable competitor experience and under a
regulatory framework which may change substantially as the Brazilian paging
industry develops.
 
    The Company currently is deploying a paging network in the Initial Markets,
plans to have substantially completed the buildout of its paging networks in the
Expansion Markets by the first quarter of 1999 and has recently launched
commercial services in Sao Paulo. The continuing development, construction and
operation of the Company's paging network is expected to place significant
demands on the Company's management and operational and financial resources and
there can be no assurance that delays in completing the planned buildout and
launching service will not occur and adversely affect the Company's liquidity
and results of operations. The Company's future performance will depend, in
part, on the Company's ability to implement its operational and financial
systems successfully and on a timely basis (including certain of its management
information systems), to expand substantially its employee base and to train and
manage its employees, including customer service, marketing and sales personnel.
 
    The Company first generated revenues in March 1997 and has experienced
cumulative negative cash flow of approximately US$18 million from inception
through March 31, 1997. The Company expects to continue to experience
substantial negative cash flow and operating losses as it develops its paging
infrastructure and rolls out its services. The Company anticipates that its
negative cash flow and operating losses will increase significantly in the
foreseeable future, and there can be no assurance that the Company will ever be
profitable or will generate positive cash flow in future years. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business."
 
    NEED FOR ADDITIONAL FINANCING AND LIQUIDITY.  The net proceeds from the sale
of the Old Notes available for use by the Company (together with cash expected
to be on hand as of the closing of the offering of the Old Notes of
approximately US$9 million) will be used to fund operating losses, capital
expenditures, and working capital needs in the development of the Initial
Markets. While the Company believes that these funds will be sufficient for the
planned development of the Initial Markets, there can be no assurance that
operating losses will not exceed expectations or that unanticipated expenditures
will not be necessary or desirable. In addition, the Company will require
additional licenses in order to achieve the capacity necessary to fully
implement its strategy for the Initial Markets. The Company is expected to
require additional financing to fund the buildout of paging infrastructure in
the Expansion Markets and to fund operating losses associated with the rollout
of services in such markets. The Company has no committed sources of financing
and there can be no assurance that additional financing will be available to the
Company on acceptable terms when required. Such additional financing may take
the form of additional debt, thereby further substantially increasing the total
leverage of the Company and the risks to holders of the Notes associated
therewith. If adequate sources of additional financing are not available, the
Company may be forced to delay, scale back or eliminate any portion of its plans
and may be unable to meet its obligations in respect of the Notes and other
liabilities as they become due. Any additional financing may take the form of
debt or equity; however, it is presently expected that a substantial portion of
the additional financing required will take the form of debt. In addition, it
should be noted that, for so long as the Company would constitute a PFIC for
U.S. federal income tax purposes (which is expected to continue through 1998),
it may be difficult for the Company to pursue a public equity offering to U.S.
persons. See "Tax Considerations--United States," "--Substantial Indebtedness;
Effect of Financial Leverage" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
    SUBSTANTIAL INDEBTEDNESS; EFFECT OF FINANCIAL LEVERAGE.  Following the
issuance of the Old Notes, the Company has indebtedness that is substantial in
relation to its shareholders' equity and cash flow. As of March 31, 1997, after
giving effect to the offering of the Old Notes, the Company would have had an
aggregate of approximately US$125.0 million of indebtedness outstanding,
representing the Old Notes, or 80% of total invested capital. The Company is
expected to incur substantial additional indebtedness following the offering of
the Old Notes in the future to pursue its business strategy. See "--Need for
 
                                       19

Additional Financing and Liquidity" and "Capitalization." As a result of the
substantial indebtedness of the Company following the offering of the Old Notes,
fixed charges of the Company are expected to exceed its earnings for the
foreseeable future and there can be no assurance that the Company's operating
cash flow will be sufficient to pay interest on the Notes following the
termination of the escrow arrangement for the Notes or to pay Additional Amounts
or Additional Interest at any time. In addition, the Indenture imposes, and
other agreements governing future indebtedness may contain, significant
operating and financial restrictions on the Company. Such restrictions will
affect, and in many respects significantly limit or prohibit, among other
things, the ability of the Company to incur additional indebtedness and pay
dividends. These restrictions, in combination with the leveraged nature of the
Company, could limit the ability of the Company to effect future financings or
otherwise may restrict the Company's activities. Substantial leverage poses the
risk that the Company may not be able to generate sufficient cash flow to
service its indebtedness, including the Notes, and to adequately fund its
operations. The Indenture permits the Company to incur additional indebtedness
under certain conditions, and the Company expects to incur substantial
additional indebtedness as so permitted. See "Description of the Notes."
 
    The Company's leverage could have important consequences to the holders of
the Notes, including the following: (i) the Company's ability to obtain
additional financing for working capital, capital expenditures, acquisitions,
general corporate purposes or other purposes may be impaired in the future; (ii)
a substantial portion of the Company's cash flow from operations must be
dedicated to the payment of principal of and interest on its indebtedness,
thereby reducing the funds available to the Company for other purposes; (iii)
the Company's leverage may hinder its ability to adjust rapidly to changing
market conditions; and (iv) the leverage could make the Company more vulnerable
in the event of a downturn in general economic conditions or its business.
 
    UNCERTAINTIES ASSOCIATED WITH A NEW INDUSTRY; CUSTOMER ACCEPTANCE AND MARKET
DEMAND.  The success of the Company's operating strategies is subject to factors
that are beyond the control of the Company and impossible to predict due, in
part, to the limited history of paging services in Brazil. Consequently, the
size of the Brazilian market for paging services, the rates of penetration of
that market, the acceptance of paging by subscribers and commercial advertisers,
the sensitivity of potential subscribers to the price of equipment and monthly
fees, the extent and nature of the competitive environment and the immediate and
long-term viability of paging services in Brazil are uncertain.
 
    DEPENDENCE ON PAGENET TECHNICAL SERVICES AND SUPPORT.  The Company has
entered into the Technical Services Agreement with PageNet for the provision of
technical services and support. The initial term of the Technical Services
Agreement is five years (through December 1, 2001). The term may be extended for
successive three-year terms unless either party provides notice of termination
at least one year prior to expiration. PageNet may, however, terminate the
agreement (a) six months after it ceases to beneficially own five percent of the
shares of Common Stock of the Company (the "Common Stock") on a fully diluted
basis or (b) if any person other than Warburg Pincus owns 50% or more of the
Common Stock on a fully diluted basis. The license to use the PageNet name in
Brazil will survive any termination of the Technical Services Agreement absent a
breach by the Company of its obligations thereunder or if Brazilian governmental
action requires a termination of the license. If PageNet were to fail to perform
its obligations thereunder or the Technical Services Agreement were terminated
or expired without renewal, there can be no assurance that the Company would
find another provider of such services and support, which could have a material
adverse effect on the Company's results of operations and financial condition.
See "Certain Transactions--Formation Transactions."
 
    REGULATION AND OWNERSHIP OF LICENSES.  Substantially all of the Company's
business activities are regulated by the Brazilian Ministry of Communications
(the "Ministry of Communications"). Such regulation relates to the licensing of
paging services, the construction of paging infrastructure and foreign
investment
 
                                       20
<PAGE>
in paging license holders, among other things. Changes in these regulations or
in the interpretation of existing regulations and the authorization of competing
technologies on an advantageous basis may materially adversely affect the
Company. Under applicable provisions of Brazilian law currently in effect, a
license to operate a paging system in Brazil may not be transferred for a period
of three years following the date on which such license is built out by its
initial license holder and without prior approval of the Ministry of
Communications. Applicable paging regulations allow license holders to enter
into mutual operating agreements which permit third parties to resell paging
services. The licenses pursuant to which the Company will conduct its business
are held by certain license holders (the "Licenseholders") and the Company has
entered into operating agreements with the Licenseholders. The Company also has
entered into transfer agreements with the Licenseholders for the transfer of the
licenses to the Company after such three-year period subject to necessary
approvals or such earlier date as permissible by the Ministry of Communications.
There also can be no assurance that the Ministry of Communications will approve
the transfer of the licenses upon the expiration of the three-year period during
which such transfer is prohibited. See "Certain Transactions--Formation
Transactions."
 
    The agreements with the Licenseholders are also subject to the risk that the
Licenseholders may undergo bankruptcy or "concordata" proceedings which may
result in the rejection or termination of the operating agreements. Further,
there is a risk that acts or omissions by a Licenseholder could result in the
revocation of its paging license or the unavailability of such license to the
Company. While certain covenants have been included in the operating agreements
to limit such risk, there can be no assurance that such covenants will not be
violated or rendered ineffective. See "Certain Transactions--Formation
Transactions."
 
    In addition, the Company's ability to use paging licenses, to cause them to
be renewed when they expire and to secure the use of new licenses in the future
is essential to the Company's operations. However, these licenses are granted by
the Ministry of Communications, and there can be no assurance that this
governmental agency will not seek to unilaterally limit, revoke or otherwise
adversely modify the terms of these licenses or the Company's ability to use
such licenses in the future, any of which could have a material adverse effect
on the Company; and in such event the Company may have limited or no legal
recourse. Furthermore, there can be no assurance that renewals of these licenses
will be granted or, if renewed, that the renewal terms will not be on
substantially less favorable terms, any of which could have a material adverse
effect on the Company. See "Business--Government Regulation."
 
    DEPENDENCE ON KEY PERSONNEL.  The success of the Company and its growth
strategy depends in large part on the ability of the Company to attract and
retain key management, marketing and operating personnel and, in particular the
Company's current President and Vice President of Operations. There can be no
assurance the Company will continue to attract and retain the qualified
personnel needed for its business. The failure of the Company to retain the
services of such officers and other key personnel could have a material adverse
effect on the Company's results of operations and financial condition. The
Company has entered into employment agreements, containing non-competition and
non-solicitation provisions, with its President and Vice President of
Operations. The Company believes that its future success will depend, in part,
on its ability to attract and retain highly talented managerial personnel. There
can be no assurance that it will be able to attract and retain the personnel it
requires on acceptable terms. See "Management--Employment Agreements."
 
    DEPENDENCE ON SATELLITES.  The Company's business is dependent upon the
operation of satellites by third parties. In order to service its paging
business, the Company utilizes BrasilSat One, a Brazilian satellite, under a
five-year contract with Embratel Sistema Telebras, the Brazilian state-owned
satellite and long distance telephone company. Although the Company has not
experienced nor does it expect to experience any significant disruption of its
transmissions, satellites are subject to significant risks that may prevent or
impair proper commercial operations, including satellite defects, destruction
and damage,
 
                                       21
<PAGE>
incorrect orbital placement and transmission interference from various causes,
including poor weather. See "Business--Paging Systems Equipment."
 
    COMPETITIVE INDUSTRY.  The wireless communications industry in Brazil has
been and is expected to be highly competitive. The Company competes with
providers of paging services utilizing 35 MHz band and 931 MHz band delivery
systems and any new wireless telecommunications technology systems which may be
introduced, as well as telephone and cellular services generally. A number of
the Company's potential competitors have greater experience in the Brazilian
paging industry than the Company and certain of its competitors may have access
to significant debt or equity capital to pursue aggressive business plans. The
Company presently expects that it will compete with, among others, paging
networks operated by Vicom Servicos de Radiochamada Ltda. ("Teletrim"), Mobitel
S.A. Telecomunicacoes ("Mobitel"), Promptel e Comunicacoes S.A. ("Conectel"),
Ino Servicos Especializados de Telecomunicacoes Ltda. ("Powernet"), a company
partially owned by Motorola International Development Corporation, and Intelco
S.A. ("Intelco"). In addition, future technological advances in the
telecommunications industry could create new services or products competitive
with the paging services currently provided by the Company. There can be no
assurance that the Company would not be adversely affected by such new services
or products. See "Business--Competition."
 
    INVESTMENT COMPANY ACT OF 1940.  The Investment Company Act of 1940, as
amended, subjects "investment companies" to registration and regulation.
Generally, an investment company is an issuer that is or is deemed to be
primarily engaged in the business of investing, reinvesting or trading in
certain securities. The Company intends to invest the net proceeds of the
offering of the Old Notes (after acquiring the Pledged Securities) in cash
equivalents pending utilization as set forth in "Use of Proceeds." The Company
will invest the net proceeds of the Offering in such a manner as will cause it
not to be an "investment company" for purposes of the Investment Company Act of
1940.
 
    In addition, as Holding LLC's sole business is to hold Common Stock of the
Company and certain cash assets, under certain circumstances Holding LLC might
be deemed to be an investment company subject to registration and regulation by
reason of its activities. Holding LLC has been advised by its counsel that so
long as the Company is a "majority-owned subsidiary" (as defined under the
Investment Company Act of 1940) of Holding LLC, Holding LLC will not be deemed
to be an investment company. The Company has agreed not to become an "investment
company" in the Indenture and Holding LLC has agreed not to become an investment
company in certain agreements to which it is a party. However, due to actions
beyond the control of the Company and Holding LLC, there can be no assurance
that the Company or Holding LLC will not be deemed to be an investment company
in the future. Potential investors in the New Notes should consult with their
own legal advisors with respect to the consequences, if any, to them as a result
of acquiring or holding such New Notes if either the Company or Holding LLC were
deemed to be an investment company, or a company owned or controlled by an
investment company.

    ABSENCE OF PUBLIC MARKET.  There is no existing trading market for the New
Notes and there can be no assurance regarding the future development of a market
for the New Notes, the ability of holders of any of the New Notes to sell such
New Notes or the price at which such holders may be able to sell their New
Notes. If such a market were to develop, the New Notes could trade at prices
that may be higher or lower than the initial offering price depending on many
factors, including prevailing interest rates, the Company's operating results,
the market for similar New Notes and general macroeconomic and market conditions
in Brazil. The Company does not presently intend to apply for listing of any of
the New Notes on any national Securities exchange or on the NASDAQ system.

                                  THE COMPANY
 
    The Company is a corporation (SOCIEDADE ANONIMA) organized in December 1996
under the laws of Brazil. The Company's predecessor was formed in April 1996 by
Warburg Pincus and members of the Company's senior management. The Company's
principal executive offices are located at Rua Alexandre Dumas, 1,711, Chacara
Santo Antonio, Sao Paulo, 04717-004, Brazil, and its telephone number is
011-55-11-538-3800.
 
    Holding LLC is a limited liability company organized in March 1997 under the
laws of Delaware. Holding LLC's principal executive offices are located at c/o
Warburg, Pincus Ventures, L.P., 466 Lexington Avenue, New York, New York 10017.
Holding LLC's sole assets will be Common Stock of the Company and cash which
will be used to fund expenses of Holding LLC. See "Certain
Transactions--Restructuring Transactions."
 
    The following chart sets forth the Company's ownership structure:

                                USE OF PROCEEDS
 
    The Company will not receive any cash proceeds from the issuance of the New
Notes offered hereby. In consideration for issuing the New Notes as described in
this Prospectus, the Company will receive in exchange Old Notes in like
principal amount, the terms of which are identical in all material respects to
those of the New Notes, except that the New Notes have been registered under the
Securities Act and are issued free of any covenant regarding transfer
restrictions. The Old Notes surrendered in exchange for the New Notes will be
retired and cancelled and cannot be reissued. Accordingly, the issuance of the
New Notes will not result in any change in the indebtedness of the Company.
 
    The net proceeds received by the Company from the sale of the Old Notes were
approximately US$120.0 million. Of these net proceeds, approximately US$46
million were used to purchase the Pledged Securities. The scheduled interest and
principal payments on Pledged Securities will be in an amount sufficient to
provide for payment in full when due of the first six scheduled interest
payments (exclusive of any Additional Amounts or Additional Interest which may
become payable) on the Notes through June 6, 2000.
 
    The Company intends to use the net proceeds (after purchasing the Pledged
Securities), together with the cash expected to be on hand as of June 6, 1997 of
approximately US$9 million, primarily to fund operating losses, capital
expenditures and working capital needs in the development and operations of the
Initial Markets. Capital expenditures will include the purchase of pagers for
leasing, transmitters and other equipment and additional licenses in the Initial
Markets. The remaining proceeds are expected to be used for working capital and
general corporate purposes in the Initial Markets and, to the extent available,
for the buildout of the Expansion Markets. The Company believes that the net
proceeds, together with the cash on hand, will be sufficient to fund the
buildout of the Initial Markets.
 
    The Pledged Securities have been pledged as security for payment of interest
and, under certain circumstances, repayment of principal of, the Notes. See
"Description of the Notes--Escrow Account." The Trustee holds the Pledged
Securities pursuant to a Pledge Agreement pending disbursement.
 
    Because of the number of factors that will determine when and how the
Company funds its capital expenditures and operations, management will retain a
significant amount of discretion over the application of the net proceeds of the
sale of the Old Notes. Pending application of the available net proceeds, the
Company will invest these net proceeds (exclusive of the Escrow Account) in cash
equivalents.

                               EXCHANGE RATE DATA
 
    There are two legal foreign exchange markets in Brazil: the Commercial
Market and the Floating Market. The Commercial Market is reserved primarily for
foreign trade transactions and transactions that generally require prior
approval from Brazilian monetary authorities, including the purchase and sale of
registered investments by foreign persons and related remittances of funds
abroad. Purchases of foreign exchange in the Commercial Market may be carried
out only through a financial institution in Brazil authorized to buy and sell
currency in that market. The "Commercial Market Rate" is the commercial selling
rate for Brazilian currency into U.S. dollars, as reported by the Central Bank.
The "Floating Market Rate" generally applies to transactions to which the
Commercial Market Rate does not apply. Prior to the implementation of the Real
Plan, the Commercial Market Rate and the Floating Market Rate differed
significantly at times. Since the introduction of the REAL, the two rates have
not differed significantly, although there can be no assurance that there will
not be significant differences between the two rates in the future. Both the
Commercial Market Rate and the Floating Market Rate are reported by the Central
Bank on a daily basis.
 
    Both the Commercial Market Rate and the Floating Market Rate are freely
negotiated but are strongly influenced by the Central Bank, which typically
intervened in the Commercial Market, prior to the implementation of the Real
Plan, in order to control fluctuations and to regulate disparities between the
Commercial Market Rate and the Floating Market Rate. After implementation of the
Real Plan, the Central Bank allowed the REAL to float with minimal intervention.
However, as described below, on March 6, 1995, the Central Bank announced its
intention to intervene in the foreign exchange markets and has subsequently
intervened in the markets and taken other actions affecting such markets.
 
    On August 1, 1993, the CRUZEIRO REAL replaced the CRUZEIRO as the unit of
Brazilian currency, with each CRUZEIRO REAL being equal to 1,000 CRUZEIROS.
Beginning in 1994, the Brazilian Government began implementation of the Real
Plan. On July 1, 1994, the REAL replaced the CRUZEIRO REAL as the unit of
Brazilian currency, with each REAL being equal to 2,750 CRUZEIROS REAIS and
having an exchange rate of R$1.00 to US$1.00. According to Brazilian law, the
issuance of REAIS is controlled by quantitative limits backed by a corresponding
amount of U.S. dollars in reserves, but the Brazilian Government subsequently
expanded those quantitative limits and allowed the REAL to float, with parity
between the REAL and the U.S. dollar (R$1.00 to US$1.00) as a ceiling.
 
    On March 6, 1995, the Central Bank announced that it would intervene in the
market and buy or sell U.S. dollars, establishing a band (FAIXA DE FLUTUACAO) in
which the exchange rate between the REAL and the U.S. dollar could fluctuate.
The Central Bank initially set the band with a floor of R$0.86 per US$1.00 and a
ceiling of R$0.90 per US$1.00 and provided that, from and after May 2, 1995, the
band would fluctuate between R$0.86 and R$0.98 per US$1.00. Shortly thereafter,
the Central Bank issued a new directive providing that the band would be between
R$0.88 and R$0.93 per US$1.00. On June 22, 1995, the Central Bank issued another
directive providing that the band would be between R$0.91 and R$0.99 per US$1.00
and subsequently reset the band on January 30, 1996 to between R$0.97 and R$1.06
per US$1.00. There can be no assurance that the band will not be altered in the
future. See "Risk Factors--Factors Relating to Brazil--Economic Uncertainty;
Effects of Exchange Rate Fluctuations" and "--Factors Relating to
Brazil--Controls and Restrictions on U.S. Dollar Remittances." On June 7, 1996,
the Commercial Market rate as reported by the Central Bank was R$0.99910 per
US$1.00. On February 18, 1997, the Central Bank again reset the band to between
R$1.05 and R$1.14 per US$1.00.

    Brazilian law provides that whenever there is a material imbalance, or a
serious risk of a material imbalance, in Brazil's balance of payments, the
Brazilian Government may, for a limited period of time, impose restrictions on
the remittance to foreign investors of the proceeds of their investments in
Brazil, as it did for approximately six months in 1989 and early 1990, as well
as on the conversion of the Brazilian currency into foreign currencies.
 
    The Brazilian Government currently restricts the ability of Brazilian or
foreign persons or entities to convert Brazilian currency into U.S. dollars or
other currencies other than in connection with certain authorized transactions.
The Central Bank has authorized the issuance of the Notes and, although there
can be no assurance, is expected, in due course, after the Closing Date, to
issue a certificate of registration authorizing each of the scheduled payments
of principal of, premium on, and interest on the Notes or for payments of
principal of, premium on and interest on the Notes upon any early redemption of
the Notes at the option of a holder of Notes. However, consent from the Central
Bank is needed for the payment of principal of, premium, if any, on and interest
on the Notes upon acceleration of the Notes following an Event of Default or for
certain late payments of the Notes (I.E., payments made 181 days or more after a
scheduled payment date). In addition, consent from the Central Bank is needed
for (i) payments in respect of the Notes upon redemption by the Company in the
event of certain changes in Brazilian law relating to tax withholding, as
described under "Description of the Notes--Redemption--Redemption for Changes in
Withholding Taxes," (ii) payments in respect of the Notes in the event of
redemption of the Notes by the Company, as described under "Description of the
Notes--Redemption--Optional Redemption by the Company," (iii) payments in
respect of the Notes in the event of an Asset Sale Offer, as described under
"Description of the Notes--Certain Covenants--Disposition of Proceeds of Asset
Sales," and (iv) payments in respect of the Notes in the event of a Change of
Control Offer, as described under "Description of the
Notes--Redemption--Mandatory Redemption--Offers to Purchase upon Change of
Control and Certain Asset Sales." There can be no assurance that any required
consent from the Central Bank will be obtained.
 
    There can be no assurance that the Brazilian Government will not in the
future impose more restrictive foreign exchange regulations that would have the
effect of eliminating or restricting the Company's access to foreign currency
that would be required to meet its foreign currency obligations, including the
Notes. The likelihood of the imposition of such restrictions by the Brazilian
Government may be affected by, among other factors, the extent of Brazil's
foreign currency reserves, the availability of sufficient foreign currency on
the date a payment is due, the size of Brazil's debt service burden relative to
the economy as a whole, Brazil's policy toward the International Monetary Fund
and political constraints to which Brazil may be subject.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH THE
FINANCIAL STATEMENTS, INCLUDING THE NOTES THERETO, INCLUDED ELSEWHERE IN THIS
PROSPECTUS, AND IN CONJUNCTION WITH THE DISCUSSION OF THE METHOD OF PRESENTATION
OF FINANCIAL INFORMATION UNDER "SELECTED FINANCIAL DATA." AS A NEW BUSINESS, THE
COMPANY IS SUBJECT TO ALL OF THE SUBSTANTIAL RISKS INHERENT IN THE COMMENCEMENT
OF A NEW BUSINESS ENTERPRISE WITH NEW MANAGEMENT. ALTHOUGH THE COMPANY BEGAN
GENERATING REVENUES IN MARCH 1997, THERE CAN BE NO ASSURANCE THAT THE COMPANY
WILL BE PROFITABLE. ADDITIONALLY, THE COMPANY HAS A LIMITED BUSINESS HISTORY
THAT INVESTORS CAN ANALYZE TO AID THEM IN MAKING AN INFORMED JUDGMENT AS TO THE
MERITS OF AN INVESTMENT IN THE COMPANY.
 
OVERVIEW
 
    The Company commenced the buildout of its paging service in May 1996 and
began offering paging service in Sao Paulo in January 1997. The Company has also
substantially completed the buildout of its paging system in Rio de Janeiro,
where the Company expects to begin offering paging service in the first quarter
of 1998, and has installed transmitters in eight additional cities in Brazil.
 
    Revenues are expected to increase as the Company adds subscribers and
receives monthly fees from a growing subscriber base. As the Company continues
to develop systems, positive EBITDA(1) from more developed systems is expected
to be offset partially or completely by corporate overhead, negative EBITDA from
less developed systems and from development costs associated with establishing
new systems. This trend is expected to continue until the Company has a
sufficiently large subscriber base to absorb operating and development costs of
new systems or no longer develops or invests in new systems.
 
    The Company both leases and sells pagers to customers. Average monthly
revenue and customer acquisition costs differ depending on whether the customer
leases or purchases the pager.
 
    LEASED PAGER CUSTOMERS.  In addition to the initial capital investment, each
new subscriber requires an incremental investment which will vary based on the
type of product and service purchased. In the Sao Paulo market, for example, the
Company expects the acquisition cost for a customer who leases a pager to
consist primarily of the cost of the pager, the cost of terminal capacity,
certain other equipment and supplies, marketing and selling costs. The Company
capitalizes pager costs and depreciates these costs over 2 1/2 years. The
Company expenses marketing and selling costs. The Company does not anticipate
charging its subscribers a service initiation fee, although it may decide to
charge such a fee in the future in certain markets. Monthly revenue per
subscriber is expected to be approximately US$40 on average in 1997 (which
includes the monthly leasing charge), and is expected to fall moderately over
time.
 
    PURCHASED PAGER CUSTOMERS.  In the Sao Paulo market, the Company expects the
acquisition cost for a customer who purchases a pager to consist primarily of
the cost of terminal capacity, certain other equipment and supplies, marketing
and selling costs. The Company expenses the cost of the pager, marketing and
selling costs. Monthly revenue per subscriber is expected to be approximately
US$28 on average in 1997 and is expected to fall moderately over time.
 
- ------------------------
 
(1) EBITDA is defined as operating income (loss) plus depreciation, amortization
    and non-cash charges. EBITDA is a commonly used measure of performance in
    the paging industry. While EBITDA should not be construed as a substitute
    for operating income (loss) or a better measure of liquidity than cash flow
    from operating activities, each of which is determined in accordance with
    U.S. GAAP, it is included herein to provide additional information regarding
    the ability of the Company to meet its capital expenditures, working capital
    requirements and any future debt service. EBITDA, however, is not
    necessarily a measure of the Company's ability to fund its cash needs,
    because it does not include capital expenditures, which the Company expects
    to continue to be significant.
 
                                       30
<PAGE>
    The Company's operating revenues consist primarily of monthly fees paid by
subscribers for paging service and leasing costs. System operating expenses
include a portion of costs of compensation and benefits for the Company's
employees, transmitter site rentals, telephone line costs, pager costs,
transmission costs, vehicle rental costs, repair and maintenance expenditures
and service call costs. Depreciation and amortization expenses consist primarily
of depreciation of leased pagers, transmitters, paging terminals, telephone
lines and cost of network installation.
 
    The development of a new system requires significant expenditures, a
substantial portion of which are incurred before the realization of revenues.
These expenditures, together with the associated early operating expenses,
result in negative cash flow until an adequate revenue generating subscriber
base is established. As the subscriber base increases, revenues, as well as some
costs, generally increase while other costs remain constant or increase at
proportionately lower levels. Accordingly, although costs increase in the
aggregate as the subscriber base grows, the average costs per subscriber
generally decrease and operating margins generally increase.
 
RESULTS OF OPERATIONS
 
THREE MONTHS ENDED MARCH 31, 1997
 
    During the three months ended March 31, 1997, the Company began to market
its paging services in Sao Paulo. During such three-month period, the Company
generated US$42,106 in operating revenues, had cost of sales of US$18,128 and
incurred selling and general administrative expenses of US$3,460,810 in
connection with the marketing of its services and the continued buildout of its
paging network. These expenses consisted primarily of payroll expenses,
professional fees, advertising expenses and rent.
 
    The Company earned interest income in the three months ended March 31, 1997
of US$205,143 and had exchange translation losses of US$233,634.
 
    As a result, the Company incurred a net loss in the three month period ended
March 31, 1997 of US$3,465,323. The loss is primarily attributable to the
expenses incurred during the period in connection with the continued development
of the Company's business.
 
PERIOD FROM INCEPTION THROUGH DECEMBER 31, 1996
 
    During the period from inception through December 31, 1996, the Company did
not generate any operating revenues. The Company incurred expenses of
US$4,961,639 in connection with the commencement of operations and the buildout
of its service. These expenses primarily consisted of payroll expenses,
professional fees and rent.
 
    The Company earned interest income in such period of US$117,210 and had
exchange and translation losses of US$60,179.
 
    As a result, the Company incurred a net loss in such period of US$4,904,608.
This loss is primarily attributable to the expenses incurred during the period
in connection with the development of the Company's business.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company's operations and expansion into new markets and products lines
will require substantial capital investment for the development and installation
of paging systems and for the procurement of pagers and paging equipment.
 
    The Company commenced the buildout of systems for its paging services in May
1996 and plans to substantially complete the buildout of the Initial Markets by
the first quarter of 1998 and the Expansion
 
                                       31
<PAGE>
Markets by the first quarter of 1999. As of June 6, 1997, the Company has (1)
completed the buildout of its Sao Paulo system, which is currently serving
approximately 3,500 subscribers, (2) installed transmitters in the Existing
Coverage Area, including Rio de Janeiro, where the system buildout is
substantially complete, and (3) hired the personnel and infrastructure necessary
to support the Company's Sao Paulo operations. The Company expects that the
available net proceeds of the Offering of the Old Notes, together with cash on
hand, will be sufficient to complete the planned buildout of the Initial Markets
and that it will need to secure additional financing to complete the planned
buildout of the Expansion Markets. See "Use of Proceeds."
 
    The principal capital expenditure requirements to construct a paging system
involve the acquisition of pagers for leasing and the acquisition and
installation of transmission facilities, both of which are directly related to
the demand for paging service. Additional capital is required to fund operating
losses incurred during the initial stages of constructing and rolling out
services. The Company currently anticipates that its cash requirements
(comprised of capital expenditures, working capital requirements, debt service
requirements and anticipated operating losses) from inception in May 1996
through December 2000, will be approximately US$150 million, including
approximately US$100 million in capital expenditures, of which approximately
US$55 million is attributable to the purchase of pagers for leasing. The Company
estimates that, of the US$150 million, approximately US$80 million will be
required to fund the capital requirements for the Initial Markets through 2000.
The actual amounts required by the Company will vary based upon the time and
success of the Company's rollout of services in its markets as well as the mix
between leased and purchased pagers. If demand for the Company's services is
less than expected, the Company should be able to reduce certain costs that are
to a large extent demand driven and/or delay the rollout of its services in the
Expansion Markets.
 
    The Company also from time to time may selectively pursue the acquisition of
existing paging systems, although it currently has no pending acquisitions. The
Company may implement alternative technologies in the future. If such new
systems are launched, acquisitions are consummated or alternative technologies
implemented, substantial additional funds may be required. The Company intends
to fund such future cash requirements through the issuance of additional debt
and/or equity capital, joint ventures or other arrangements. There can be no
assurance that the Company will be able to obtain such debt or equity capital on
satisfactory terms, or at all, to meet its future financing needs.
 
    The Company has raised approximately US$155 million from issuance of the
Company's redeemable preferred stock and the Old Notes. While the Company
believes that the available portion of these funds will be sufficient for the
planned development of the Initial Markets, there can be no assurance that
operating losses will not exceed expectations or that unanticipated expenditures
will not be necessary or desirable. In addition, commencing in December 2002,
subject to restrictions on the Company's ability to pay dividends contained in
the Indenture, dividends on the Company's Preferred Stock will be payable
quarterly in cash out of earnings and profits of the Company. The Company's
liquidity may also be adversely affected by statutory minimum dividend
requirements that require the distribution of 25% of net income of a company, as
determined under applicable Brazilian law. Moreover, if growth exceeds
expectations, additional funds may be required to finance the Company's
expansion. The Company will also require additional financing to buildout and
commence services in the Expansion Markets. The Company has no committed sources
of financing and there can be no assurance that additional financing will be
available to the Company on acceptable terms when required. If adequate sources
of additional financing are not available, the Company may be forced to delay,
scale back or eliminate any portion of its plans. See "Risk Factors--Risk
Factors Relating to the Company and the Offering--Need for Additional Financing
and Liquidity."
 
    The Company has used approximately US$46 million of the net proceeds to
purchase a portfolio of securities, to be held in the United States, consisting
of U.S. Government Securities, that are pledged as
 
                                       32
<PAGE>
security sufficient to cover the first six payments of interest on the Notes
through June 6, 2000 and, under certain circumstances, as security for repayment
of principal of the Notes. See "Use of Proceeds."
 
INFLATION AND EXCHANGE RATES
 
    Inflation and exchange rate variations may have substantial effects on the
Company's results of operations and financial condition. In periods of
inflation, many of the Company's expenses will tend to increase. Generally, in
periods of inflation, a company is able to raise its prices to offset the rise
in its expenses and may set its prices without government regulation. However,
under Brazilian law designed to reduce inflation, the rates which the Company
may charge to a particular subscriber may not be increased until the next
anniversary of the subscriber's initial subscription date. Thus, the Company is
less able to offset expense increases with revenue increases.
 
    Generally, the effects of inflation in Brazil have been offset in part by
devaluation of the Brazilian currency relative to the U.S. dollar. Devaluation
of the REAL may also have an adverse effect on the Company. The Company collects
substantially all of its revenues in REAIS, but pays certain of its expenses,
including interest on the Notes and a significant portion of its equipment
costs, in U.S. dollars. To the extent the REAL depreciates at a rate greater
than the rate at which the Company raises prices, the value of the Company's
revenues (as expressed in U.S. dollars) may be adversely affected. This effect
on the Company's revenues may negatively impact the Company's ability to fund
U.S. dollar-based expenditures. The Company may experience economic loss with
respect to its investments and fluctuations in its reported results of
operations solely as a result of currency rate fluctuations, which may have a
material adverse effect on the Company's financial condition. The Company
intends to explore various alternatives that may be available to hedge exchange
rate risks, although there can be no assurance that any such alternatives will
be available on terms acceptable to the Company. Accordingly, devaluation of the
REAL may have a material adverse effect on the Company's results of operations
and financial condition.

                               THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
    In connection with the sale of the Old Notes, the Company entered into the
Notes Registration Rights Agreement with the Initial Purchasers, pursuant to
which the Company agreed to use its best efforts to file with the Commission a
registration statement with respect to the exchange of the Old Notes for a
series of registered debt securities with terms identical in all material
respects to the terms of the Old Notes, except that the New Notes are issued
free from any covenant regarding transfer restrictions, and except that if the
Exchange Offer is not consummated by November 3, 1997, the interest rate borne
by the Old Notes will increase by 0.50% per annum for the first 90-day period
following November 3, 1997 and will increase by an additional 0.50% per annum
with respect to each subsequent 45-day period up to a maximum amount of 2.00%
per annum.
 
    The Company is making the Exchange Offer in reliance on the position of the
staff of the Commission as set forth in certain no-action letters addressed to
other parties in other transactions. However, the Company has not sought its own
no-action letter and there can be no assurance that the staff of the Commission
would make a similar determination with respect to the Exchange Offer as in such
other circumstances. Based upon these interpretations by the staff of the
Commission, the Company believes that New Notes issued pursuant to this Exchange
Offer in exchange for Old Notes may be offered for resale, resold and otherwise
transferred by a holder thereof other than (i) a broker-dealer who purchased
such Old Notes directly from the Company to resell pursuant to Rule 144A or any
other available exemption under the Securities Act or (ii) a person that is an
"affiliate" (as defined in Rule 405 of the Securities Act) of the Company
without compliance with the registration and prospectus delivery provisions of
the Securities Act, provided that such New Notes are acquired in the ordinary
course of such holder's business and that such holder is not participating, and
has no arrangement or understanding with any person to participate, in the
distribution of such New Notes. Holders of Old Notes accepting the Exchange
Offer will represent to the Company in the Letter of Transmittal that such
conditions have been met. Any holder who participates in the Exchange Offer for
the purpose of participating in a distribution of the New Notes may not rely on
the position of the staff of the Commission as set forth in these no-action
letters and would have to comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any secondary resale
transaction. A secondary resale transaction in the United States by a holder who
is using the Exchange Offer to participate in the distribution of New Notes must
be covered by a registration statement containing the selling securityholder
information required by Item 507 of Regulation S-K of the Securities Act.
 
    Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it acquired the Old Notes as a result
of market-making activities or other trading activities and will deliver a
prospectus in connection with any resale of such New Notes. This Prospectus, as
it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of New Notes received in exchange for
Old Notes where such Old Notes were acquired by such broker-dealer as a result
of market-making activities or other trading activities. The Letter of
Transmittal states that by acknowledging and delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. The Company has agreed that for a period of 180
days after the Expiration Date, it will make this Prospectus available to
broker-dealers for use in connection with any such resale. See "Plan of
Distribution."
 
    Except as aforesaid, this Prospectus may not be used for an offer to resell,
resale or other retransfer of New Notes.
 
    The Exchange Offer is not being made to, nor will the Company accept tenders
for exchange from, holders of Old Notes in any jurisdiction in which the
Exchange Offer or the acceptance thereof would not be in compliance with the
securities or blue sky laws of such jurisdiction.

TERMS OF THE EXCHANGE
 
    Upon the terms and subject to the conditions of the Exchange Offer, the
Company will, unless such Old Notes are withdrawn in accordance with the
withdrawal rights specified in "--Withdrawal of Tenders" below, accept any and
all Old Notes validly tendered prior to 5:00 p.m., New York City time, on the
Expiration Date. The date of acceptance for exchange of the Old Notes, and
consummation of the Exchange Offer, is the Exchange Date, which will be the
first business day following the Expiration Date (unless extended as described
herein). The Company will issue, on or promptly after the Exchange Date, an
aggregate principal amount of up to US$125,000,000 of New Notes in exchange for
a like principal amount of outstanding Old Notes tendered and accepted in
connection with the Exchange Offer. The New Notes issued in connection with the
Exchange Offer will be delivered on the earliest practicable date following the
Exchange Date. Holders may tender some or all of their Old Notes in connection
with the Exchange Offer. However, Old Notes may be tendered only in integral
multiples of US$1,000.
 
    The terms of the New Notes are identical in all material respects to the
terms of the Old Notes, except that the New Notes have been registered under the
Securities Act and are issued free from any covenant regarding transfer
restrictions, and except that if the Exchange Offer is not consummated by
November 3, 1997, the interest rate borne by the Old Notes will increase by
0.50% per annum for the first 90-day period following November 3, 1997 and will
increase by an additional 0.50% per annum with respect to each subsequent 45-day
period up to a maximum amount of 2.00% per annum. The New Notes will evidence
the same debt as the Old Notes and will be issued under and be entitled to the
same benefits under the Indenture as the Old Notes. As of the date of this
Prospectus, US$125,000,000 aggregate principal amount of the Old Notes is
outstanding.
 
    In connection with the issuance of the Old Notes, the Company arranged for
the Old Notes originally purchased by qualified institutional buyers to be
issued and transferable in book-entry form through the facilities of The
Depository Trust Company ("DTC"), acting as depository. Except as described in
"Book-Entry; Delivery and Form," the New Notes will be issued in the form of a
global note registered in the name of DTC or its nominee and each holder's
interest therein will be transferable in book-entry form through DTC. See
"Book-Entry; Delivery and Form."
 
    Holders of Old Notes do not have any appraisal or dissenters' rights in
connection with the Exchange Offer. Old Notes which are not tendered for
exchange or are tendered but not accepted in connection with the Exchange Offer
will remain outstanding and be entitled to the benefits of the Indenture, but
will not be entitled to any registration rights under the Notes Registration
Rights Agreement.
 
    The Company shall be deemed to have accepted validly tendered Old Notes
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
for the purposes of receiving the New Notes from the Company.
 
    If any tendered Old Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, certificates for any such unaccepted Old Notes will be returned,
without expense, to the tendering holder thereof as promptly as practicable
after the Expiration Date.
 
    Holders who tender Old Notes in connection with the Exchange Offer will not
be required to pay brokerage commissions or fees or, subject to the instructions
in the Letter of Transmittal, transfer taxes with respect to the exchange of Old
Notes in connection with the Exchange Offer. The Company will pay all charges
and expenses, other than certain applicable taxes described below, in connection
with the Exchange Offer. See "-- Fees and Expenses."
 
                                       35
<PAGE>
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
    The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
           , 1997, unless extended by the Company in its sold discretion, in
which case the term "Expiration Date" shall mean the latest date and time to
which the Exchange Offer is extended.
 
    The Company reserves the right, in its sole discretion (i) to delay
accepting any Old Notes, to extend the Exchange Offer or to terminate the
Exchange Offer and to refuse to accept Old Notes not previously accepted, if any
of the conditions set forth below under "--Conditions to the Exchange Offer"
shall not have been satisfied and shall not have been waived by the Company (if
permitted to be waived by the Company) and (ii) to amend the terms of the
Exchange Offer in any manner. Any such delay in acceptance, extension,
termination or amendment will be followed as promptly as practicable by oral or
written notice thereof to the registered holders. If the Exchange Offer is
amended in a manner determined by the Company to constitute a material change,
the Company will promptly disclose such amendment by means of a prospectus
supplement that will be distributed to the registered holders of the Old Notes,
and the Company will extend the Exchange Offer for a period of five to ten
business days, depending upon the significance of the amendment and the manner
of disclosure to the registered holder, if the Exchange Offer would otherwise
expire during such five to ten business day period.
 
    If the Company determines to make a public announcement of any delay,
extension, amendment or termination of the Exchange Offer, the Company shall
have no obligation to publish, advertise or otherwise communicate any such
public announcement, other than by making a timely release to an appropriate
news agency.
 
INTEREST ON THE NEW NOTES
 
    The New Notes will bear interest at the rate of 13 1/2% per annum. Interest
on the New Notes shall accrue from the last Interest Payment Date (June 6 or
December 6) on which interest was paid on the Old Notes surrendered or, if no
interest has been paid on the Old Notes, from June 6, 1996.
 
    Interest on the New Notes will be payable semiannually on June 6 and
December 6 of each year, commencing on the first Interest Payment Date following
the issuance thereof.
 
    Holders of Old Notes whose Old Notes are accepted for exchange will not
receive interest on such Old Notes for any period subsequent to the last
interest payment date to occur prior to the issue date of the New Notes, and
will be deemed to have waived the right to receive any interest payment on the
Old Notes accrued from and after such interest payment date.
 
CONDITIONS TO THE EXCHANGE OFFER
 
    Notwithstanding any other term of the Exchange Offer, the Company will not
be required to accept for exchange, or to exchange, any Old Notes for any New
Notes, and may terminate or amend the Exchange Offer before the acceptance of
any Old Notes for exchange if:
 
            (a) any action or proceeding is instituted or threatened in any
       court or by or before any governmental agency relating to the Exchange
       Offer which, in the Company's reasonable good faith judgment, would be
       expected to impair the ability of the Company to proceed with the
       Exchange Offer, or
 
            (b) any law, statute, rule or regulation is adopted or enacted, or
       any existing law, statute, rule or regulation is interpreted by the
       Commission or its staff, which, in the Company's reasonable good faith
       judgment, would be expected to impair the ability of the Company to
       proceed with the Exchange Offer.
 
                                       36
<PAGE>
    If the Company determines in its reasonable good faith judgment that any of
the foregoing conditions exist, the Company may (i) refuse to accept any Old
Notes and return all tendered Old Notes to the tendering holders, (ii) extend
the Exchange Offer and retain all Old Notes tendered prior to the expiration of
the Exchange Offer, subject, however, to the rights of holders who tendered such
Old Notes to withdraw their tendered Old Notes which have not been withdrawn. If
such waiver constitutes a material change to the Exchange Offer, the Company
will promptly disclose such waiver by means of a prospectus supplement that will
be distributed to the registered holders, and the Company will extend the
Exchange Offer for a period of five to ten business days, depending upon the
significance of the waiver and the manner of disclosure to the registered
holders, if the Exchange Offer would otherwise expire during such five to ten
business days.
 
PROCEDURES FOR TENDERING
 
    Only a holder of record of Old Notes on            , 1997 may tender such
Old Notes in connection with the Exchange Offer. To tender in connection with
the Exchange Offer, a holder must complete, sign and date the Letter of
Transmittal, or a facsimile thereof, have the signatures thereon guaranteed if
required by the Letter of Transmittal and mail or otherwise deliver such Letter
of Transmittal or such facsimile, together with the Old Notes (unless such
tender is being effected pursuant to the procedure for book-entry transfer
described below) and any other required documents, to the Exchange Agent prior
to 5:00 p.m., New York City time, on the Expiration Date.
 
    Any financial institution that is a participant in DTC's Book-Entry Transfer
Facility system may make book-entry delivery of the Old Notes by causing DTC to
transfer such Old Notes into the Exchange Agent's account in accordance with
DTC's procedure for such transfer. Although delivery of Old Notes may be
effected through book-entry transfer into the Exchange Agent's Account at DTC,
the Letter of Transmittal (or facsimile thereof), with any required signature
guarantees and any other required documents, must, in any case, be transmitted
to and received or confirmed by the Exchange Agent at its addresses set forth
under the caption "Exchange Agent," below, prior to 5:00 p.m., New York City
time, on the Expiration Date. DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH
ITS PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.
 
    The tender by a holder of Old Notes will constitute an agreement between
such holder and the Company in accordance with the terms and subject to the
conditions set forth herein and in the Letter of Transmittal.
 
    The method of delivery of Old Notes and the Letter of Transmittal and all
other required documents to the Exchange Agent is at the election and risk of
the holders. Instead of delivery by mail, it is recommended that holders use an
overnight or hand delivery service. In all cases, sufficient time should be
allowed to assure deliver to the Exchange Agent before the Expiration Date. No
Letter of Transmittal or Old Notes should be sent to the Company. Holders may
request their respective brokers, dealers, commercial banks, trust companies or
nominees to effect the tenders for such holders.
 
    Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to tender
should contact the registered holder promptly and instruct such registered
holder to tender on such beneficial owner's behalf. If such beneficial owner
wishes to tender on such owner's own behalf, such owner must, prior to
completing and executing the Letter of Transmittal and delivery of such owner's
Old Notes, either make appropriate arrangements to register ownership of the Old
Notes in such owner's name or obtain a properly completed bond power from the
registered holder. The transfer of registered ownership may take considerable
time.
 
    Signature on a Letter of Transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by an Eligible Institution (as defined below) unless
the Old Notes tendered pursuant thereto are tendered (i) by a registered holder
who has not completed the box entitled "Special Payment Instructions" or
"Special Delivery Instructions" on the Letter of Transmittal, or (ii) for the
account of an Eligible
 
                                       37
<PAGE>
Institution. In the event that signatures on a Letter of Transmittal or a notice
of withdrawal, as the case may be, are required to be guaranteed, such guarantee
must be by a member firm of a registered national securities exchange or of the
National Association of Securities Dealers, Inc., a commercial bank or trust
company having an office or correspondent in the United States or an "eligible
guarantor institution" within the meaning of Rule 17Ad-15 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act") (an "Eligible
Institution").
 
    If the Letter of Transmittal is signed by a person other than the registered
holder of any Old Notes listed therein, such Old Notes must be endorsed by such
registered holder or accompanied by a properly completed bond power, in each
case signed or endorsed in blank by such registered holder as such registered
holder's name appears on such Old Notes.
 
    If the Letter of Transmittal or any Old Notes or bond powers are signed or
endorsed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and unless waived by the
Company, evidence satisfactory to the Company of their authority to so act must
be submitted with the Letter of Transmittal.
 
    All questions as to the validity, form, eligibility (including time of
receipt) and acceptance and withdrawal of tendered Old Notes will be determined
by the Company in its sole discretion, which determination will be final and
binding. The Company reserves the absolute right to reject any and all Old Notes
not properly tendered or any Old Notes whose acceptance by the Company would, in
the opinion of U.S. counsel for the Company, be unlawful. The Company also
reserves the right to waive any defects, irregularities or conditions of tender
as to any particular Old Notes either before or after the Expiration Date. The
Company's interpretation of the terms and conditions of the Exchange Offer
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Old Notes must be accrued within such time as the
Company shall determine. Although the Company intends to request the Exchange
Agent to notify holders of defects or irregularities with respect to tenders of
Old Notes, neither the Company, the Exchange Agent nor any other person shall
have any duty or incur any liability for failure to give such notification.
Tenders of Old Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived. Any Old Notes received by the Exchange
Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering holders, unless otherwise provided in the Letter of
Transmittal, as soon as practicable following the Expiration date.
 
    In addition, the Company reserves the right, as set forth above under
caption "--Conditions to the Exchange Offer," to terminate the Exchange Offer.
 
    By tendering, each holder represents to the Company that, among other
things, the New Notes acquired in connection with the Exchange Offer are being
obtained in the ordinary course of business of the person receiving such New
Notes, whether or not such person is the holder, that neither the holder nor any
such other person has an arrangement or understanding with any person to
participate in the distribution of such New Notes and that neither the holder
nor any such other person is an "affiliate" (as defined in rule 405 under the
Securities Act) of the Company. If the holder is a broker-dealer which will
receive New Notes for its own account in exchange of Old Notes, it will
acknowledge that it acquired such Old Notes as the result of market making
activities or other trading activities and it will deliver a prospectus in
connection with any resale of such New Notes. See "Plan of Distribution."
 
GUARANTEED DELIVERY PROCEDURES
 
    Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available, or (ii) who cannot deliver their Old Notes, the Letter of
Transmittal or any other required documents to the
 
                                       38
<PAGE>
Exchange Agent, or cannot complete the procedure for book-entry transfer, prior
to the Expiration Date, may effect a tender of their Old Notes if:
 
            (a) the tender is made through an Eligible Institution;
 
            (b) Prior to the Expiration Date, the Exchange Agent received from
       such Eligible Institution a properly completed and duly executed Notice
       of Guaranteed Deliver (by facsimile transmission, mail or hand delivery)
       setting forth the name and address of the holder, the certificate
       number(s) of such Old Notes and the principal amount of Old Notes
       tendered, stating that the tender is being made thereby and guaranteeing
       that with five business days after the Expiration Date, the Letter of
       Transmittal (or facsimile thereof) together with the certificate(s)
       representing the Old Notes to be tendered in proper form for transfer (or
       confirmation of a book-entry transfer into the Exchange Agent's account
       at DTC of Old Notes delivered electronically) and any other documents
       required by the Letter of Transmittal will be deposited by the Eligible
       Institution with the Exchange Agent; and
 
            (c) Such properly completed and executed Letter of Transmittal (or
       facsimile thereof) as well as the certificate(s) representing all
       tendered Old Notes in proper form for transfer (or confirmation of a
       book-entry transfer into the Exchange Agent's account at DTC of Old Notes
       delivered electronically) and all other documents required by the Letter
       of Transmittal are received by the Exchange Agent within five business
       days after the Expiration Date.
 
WITHDRAWAL OF TENDERS
 
    Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time prior to 5:00p.m, New York City time, on the Expiration Date.
 
    To withdraw a tender of Old Notes in connection with the Exchange Offer, a
written or facsimile transmission notice of withdrawal must be received by the
Exchange Agent at its address set forth herein prior to 5:00 p.m., New York City
time, on the Expiration Date. Any such notice of withdrawal must (i) specify the
name of the person who deposited the Old Notes to be withdrawn (the
"Depositor"), (ii) identify the Old Notes to be withdrawn (including the
certificate number or numbers and principal amount of such Old Notes), (iii) be
signed by the Depositor in the same manner as the original signature on the
Letter of Transmittal by which such Old Notes were tendered (including any
required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee register the transfer of such Old Notes into the
name of the person withdrawing the tender, and (iv) specify the name in which
any such Old Notes are to be registered, if different from that of the
Depositor. All questions as to the validity, form and eligibility (including
time of receipt) of such withdrawal notices will be determined by the Company,
whose determination shall be final and binding on all parties. Any Old Notes so
withdrawn will be deemed not be have been validly tendered for purposes of the
Exchange Offer and no New Notes will be issued with respect thereto unless the
Old Notes so withdrawn are validly re-tendered. Any Old Notes which have been
tendered but which are not accepted for exchange or which are withdrawn will be
returned to the holder thereof without cost to such holder as soon as
practicable after withdrawal, rejection of tender or termination of the Exchange
Offer. Properly withdrawn Old Notes may be re-tendered by following one of the
procedures described above under the caption "-- Procedures for Tendering" at
any time prior to the Expiration Date.
 
EXCHANGE AGENT
 
    The Chase Manhattan Bank has been appointed as Exchange Agent in connection
with the Exchange Offer. Questions and requests for assistance, requests for
additional copies of this Prospectus or of the Letter of Transmittal should be
directed to the Exchange Agent, at its offices at 450 West 33rd Street, 15th
Floor, New York New York 10001. The Exchange Agent's telephone number is (212)
946-3014 and facsimile number is (212) 946-8177.
 
                                       39
<PAGE>
FEES AND EXPENSES
 
    The Company will not make any payment to brokers, dealers or others
soliciting acceptances of the Exchange Offer.
 
    The Company will pay certain other expenses to be incurred in connection
with the Exchange Offer, including the fees and expenses of the Trustee,
accounting and certain legal fees.
 
    Holders who tender their Old Notes for exchange will not be obligated to pay
any transfer taxes in connection therewith. If, however, New Notes are to be
delivered to, or are to be issued in the name of, any person other than the
registered holder of the Old Notes tendered, or if tendered Old Notes are
registered in the name of any person other than the person signing the Letter of
Transmittal, or if a transfer tax is imposed for any reason other than the
exchange of Old Notes in connection with the Exchange Offer, then the amount of
any such transfer taxes (whether imposed on the registered holder or any other
persons) will be payable by the tendering holder. If satisfactory evidence of
payment of such taxes or exemption therefrom is not submitted with the Letter of
Transmittal, the amount of such transfer taxes will be billed directly to such
tendered holder.
 
ACCOUNTING TREATMENT
 
    The New Notes will be recorded at the same carrying value as the Old Notes
as reflected in the Company's accounting records on the date of the exchange.
Accordingly, no gain or loss for accounting purposes will be recognized by the
Company upon the consummation of the Exchange Offer. Any expenses of the
Exchange Offer that are paid by the Company will be amortized by the Company
over the term of the New Notes under generally accepted accounting principles.
 
CONSEQUENCES OF FAILURE TO PROPERLY TENDER OLD NOTES IN THE EXCHANGE
 
    Issuance of the New Notes in exchange for the Old Notes pursuant to the
Exchange Offer will be made only after timely receipt by the Exchange Agent of
such Old Notes, a properly completed and duly executed Letter of Transmittal and
all other required documents. Therefore, holders of the Old Notes desiring to
tender such Old Notes in exchange for New Notes should allow sufficient time to
ensure timely delivery. The Company is under no duty to give notification of
defects or irregularities with respect to tenders of Old Notes for exchange. Old
Notes that are not tendered or that are tendered but not accepted by the Company
for exchange, will, following consummation of the Exchange Offer, continue to be
subject to the existing restrictions upon transfer thereof under the Securities
Act and, upon consummation of the Exchange Offer, certain registration rights
under the Notes Registration Rights Agreement will terminate.
 
    In the event the Exchange Offer is consummated, the Company will not be
required to register the Remaining Old Notes. Remaining Old Notes will continue
to be subject to the following restrictions on transfer: (i) the Remaining Old
Notes may be resold only if registered pursuant to the Securities Act, if any
exemption from registration is available thereunder, or if neither such
registration nor such exemption is required by law, and (ii) the Remaining Old
Notes will bear a legend restricting transfer in the absence of registration or
an exemption therefrom. The Company does not currently anticipate that it will
register the Old Notes under the Securities Act. To the extent that Old Notes
are tendered and accepted in connection with the Exchange Offer, any trading
market for Remaining Old Notes could be adversely affected.

                                    INDUSTRY
 
OVERVIEW
 
    Paging provides a communications link to a paging service subscriber
throughout the paging service area. Each transmission point is comprised of a
radio transmitter which sits atop a building or tower and services the area
within an approximate 25 mile radius from its location, depending upon signal
power and the surrounding terrain. Typically, a series of transmitters are
linked together and broadcast messages simultaneously (known as simulcasting) to
cover a relatively large and densely populated region. Transmitters are also
linked together to provide national coverage for a paging service subscriber.
Generally, the cost of paging services to the subscriber increases as the area
covered by such paging services increases.
 
    The paging service subscriber carries a pager which is a radio receiver
tuned to a specific frequency and which only accepts messages sent out on that
specific frequency based on a special frequency-unique code. An individual
accesses a paging subscriber's pager by calling a paging terminal and leaving
information. Once the information is left, the paging terminal encodes the
information and sends it to each of the transmitters, which then, in turn and
simultaneously, broadcast the information in the paging service area. Typically,
a paging subscriber receives the information within less than one minute after
the information is left with the paging terminal. Transmitters can be connected
to the paging terminal by dedicated telephone lines, microwave links or
satellites. The most sophisticated paging systems use satellites to link their
transmitters. This allows for the easiest and most reliable transmission of
messages. In a satellite-linked system, the information received by the paging
terminal is encoded and sent via satellite to receivers which are attached to
each of the transmitters in the service area. The receivers then transform the
satellite signal into a signal that is simulcast in the service area for receipt
by the paging unit.
 
    The type of information left by an individual and accepted by a pager is
dependent on the type of service the subscriber has chosen. The "tone only"
pager is one of the oldest and simplest types of service, allowing the sender to
signal to the subscriber that there is a message waiting: the pager is equipped
with a beeper that, when triggered, indicates that the subscriber must call a
pre-determined telephone number, typically an answering service or the
subscriber's office, to gain additional information. The "numeric" display pager
is the most popular type of pager in the United States. A numeric pager allows a
person to send a message consisting of up to 20 numeric characters (typically a
telephone number), using a touch tone telephone, which is then displayed on the
subscriber's pager. The "alphanumeric" pager currently provides the subscriber
with the ability to receive and store the most information, allowing a person to
send a textual message containing from 40 (which is typical) up to 1,990
characters, by calling a dispatch center or by using a computer to
electronically transmit the message which is then displayed on the subscriber's
pager. In many cases, the information-rich alphanumeric message eliminates the
need to make another call or alters the timing of another call.
 
    Additional services may be combined with some of the above services for an
additional cost to the subscriber including a customized greeting to the sender,
voice mail attached to the pager which allows the sender to leave a voice
message (which must be accessed by telephone), and an extended subscriber
service area which allows a subscriber to be paged in a larger geographic area.
 
    Typically, a subscriber is assigned a unique telephone number identifying
that subscriber to the paging terminal when a call is placed to his or her
pager. However, in areas where access to direct dial telephone numbers are
limited, paging companies have employed a personal identification number ("PIN")
system whereby a sender calls a dispatch center and gives the operator the
subscriber's PIN followed by the message. The transmission of messages through
transmitters and the subsequent receipt of those messages by the pager has been
accomplished by using a number of different paging protocols that allow messages
to be broadcast at faster and faster speeds. Transmitter manufacturers have
created technology that substantially increases transmission speed, which in
turn increases frequency capacity. The most recent technological innovation,
known as FLEX-Registered Trademark-, allows for the broadcast of messages at
three times the speed and capacity of the traditional paging protocol.

THE UNITED STATES PAGING INDUSTRY
 
    The United States paging industry has been in existence since 1949 when the
Federal Communications Commission allocated a group of radio frequencies for use
in providing one-way and two-way types of mobile communications services. The
industry grew slowly at first as the quality and reliability of equipment was
developed and the market began to perceive the benefits of mobile
communications. Equipment reliability improved dramatically in the 1970s and
potential customers gained a better understanding of the time savings and
efficiencies that paging services could provide. The 1980s saw significant
developments in the paging industry. New companies began offering monthly
numeric paging service at affordable rates, thereby stimulating demand and
developing the paging industry. This development led to industry consolidation
and transformed the business from a local into a national business. Although
alphanumeric paging was available in the 1980s, it was not until the mid 1990s
with the development of the FLEX-Registered Trademark- transmission protocol
that alphanumeric service became economically viable. In addition to the growth
of alphanumeric paging, the 1990s have been characterized by three other
significant changes: the introduction of national paging at reasonable prices
allowing customers to access national coverage for less than US$30 per month,
the substantial consolidation of medium-sized paging companies and the rapid
growth in the consumer market through the development of the reseller
distribution channel.
 
    In the United States, customers utilizing numeric pagers typically pay
approximately US$65 for the pager and US$10 per month for local service, while
those who take advantage of the more sophisticated alphanumeric pagers typically
pay approximately US$150 for the pager and US$15 per month for local service and
up to US$55 per month for enhanced services, including approximately US$30 per
month for nationwide service. Depending on the credit rating of a business or an
individual, these products may be leased rather than purchased, for an
additional monthly charge of US$1 to US$3, included in the price. Each of these
services is subject to call limits and also may be augmented with additional
revenue enhancing services such as customized greetings, voice mail or extended
coverage. As prices have decreased in the United States, customers have chosen
to pay for the ability to get pages in wider geographic areas, and consequently
nationwide paging has been an increasingly important product in the United
States during the last three years.
 
PAGENET
 
    PageNet is the largest provider of paging services in the United States,
with approximately 9.5 million pagers in service in the United States as of
December 31, 1996, more than the combined number of pagers in service of the
second and third largest U.S. providers of paging services. PageNet was formed
in 1981, aggressively entered the U.S. paging market, and rapidly gained market
share to become a dominant paging service provider. In 1983, PageNet began to
build new paging systems in geographic markets not previously served by PageNet
and since then has established 49 new independent paging operations in major
metropolitan markets and regional clusters. PageNet has employed a low price and
high quality aggressive marketing strategy which has proved successful in making
it the largest paging company in the United States.
 
    PageNet, an equity owner of PageNet do Brasil, has entered into the
Technical Services Agreement which provides the Company with access to PageNet's
products, paging expertise, intellectual property (including the exclusive use
of PageNet's tradename in Brazil), volume supplier discounts and other
capabilities.
 
BRAZILIAN PAGING INDUSTRY
 
    OVERVIEW.  The paging industry in Brazil is in its formative stage. Although
paging services were first offered in 1968, the industry remained undeveloped
until the early 1990s when, following the Brazilian Government's codification of
a regulatory framework for paging services in 1991, several paging companies
entered the Sao Paulo market. In contrast to the United States, where the wide
availability of touch tone
 
                                       42
<PAGE>
telephones has made numeric pagers the service of choice, in Brazil touch tone
telephones are far less common and as a result alphanumeric paging service
accounts for approximately 95% of the paging market. Moreover, the
information-rich messages transmitted to alphanumeric pagers often eliminate the
need for a return telephone call by delivering a complete message.
 
    Paging is one of the areas within the Brazilian telecommunications sector
that is open to private investment and, over the last three years, the Brazilian
paging market has experienced rapid growth. The Company estimates that, as of
December 1996, there were approximately 800,000 pagers in operation in Brazil
(up from approximately 400,000 in 1995 and 200,000 in 1994), representing a
market penetration of less than one-half of one percent of the population and an
annual growth rate of 100% since 1994.
 
    The Company believes that the demand for paging services in Brazil is high
as a result of the convergence of three factors: Brazil's large population, its
growing and stable economy and a state-owned telephone infrastructure that is
insufficient and expensive. The waiting list to obtain ordinary telephone lines
from the local service providers is approximately one to three years and
although there has developed a private market for the immediate purchase of
telephone lines, the cost of a telephone line in the private market is
approximately US$3,000, which is often too expensive for the average wage
earner. For those who desire reliable portable communications, paging service
offers an economical alternative to cellular telephone service, which is far
more expensive and currently subject to long waiting lists to obtain service.
 
    EXISTING MARKETING STRATEGIES.  Prior to 1996, there was very little
marketing by Brazilian paging operators. Most advertising was limited to small
announcements in newspapers and in a few magazines. Paging companies had limited
financial resources and, due to significant concurrent demand for pagers,
expended few resources on promotional activities. This trend began to change in
the second half of 1995 with the entrance of new competitors into the paging
market. Operators began to focus on the need to quickly capture market share.
Consequently, several paging companies have expanded their advertising campaigns
to include radio, outdoors and full color announcements in major magazines.
 
    Currently, the Company estimates that corporate customers account for
approximately 30% of industry sales. Management believes that most major paging
operators have focused on the consumer market as opposed to the business market
which tends to be more oriented towards leasing, due to limited access to
working capital. While all major paging operators in Brazil maintain direct
sales personnel and stores, the tendency recently has been to emphasize the
development of alternative distribution channels allowing retailers to sell
pagers and paging services on behalf of the paging company to individual
customers for a fee. Generally, the paging company provides retailers with
pagers at wholesale prices and the retailer then sells the pagers to the
customer. The Brazilian reseller market, unlike the U.S. market, is in its most
formative stages. Resellers typically receive both pagers and bulk paging
service from the paging company, and provide both the pager and the paging
service to the customer, while maintaining responsibility for various
administrative costs over the life of the subscriber.
 
    Although the Sao Paulo and Rio de Janeiro metropolitan areas together
account for approximately 67% of the existing paging market in Brazil, their
paging penetration rates are only approximately 2.2% and 1.8%, respectively. As
of December 31, 1996, two companies, Teletrim and Mobitel, together accounted
for an aggregate of approximately 330,000 pagers in service including
approximately 45% of the Sao Paulo market and approximately 62% of the Rio de
Janiero market.

                                    BUSINESS
 
COMPANY OVERVIEW
 
    PageNet do Brasil's objective is to become a leading provider of paging and
wireless messaging services in Brazil. The Company has secured licenses which
enable it to broadcast paging services throughout the country and currently
serves approximately 3,500 subscribers. The Company has installed 44 paging
transmitters in the Existing Coverage Area, commenced offering paging services
in greater Sao Paulo in January 1997, and plans to begin marketing paging
services in greater Rio de Janeiro in the first quarter of 1998 and in three
additional cities in the first quarter of 1999. PageNet do Brasil was formed by
PageNet NV, a wholly owned subsidiary of PageNet, the largest paging company in
the United States, Warburg Pincus, a private equity fund, TVA, a leading pay
television company in Brazil, and a wholly owned subsidiary of Abril S.A., Latin
America's largest publishing enterprise, IVP Cayman, the general partner of
which is IVP, a private investment fund focused on Brazil, and Multiponto, an
equity investor focused on the Brazilian telecommunications sector. Management
believes that a number of factors create a favorable environment for the paging
industry in Brazil, including: (i) Brazil's large population, (ii) its growing
and stable economy, (iii) the paging market's relatively low penetration rate
and high historical growth rate, and (iv) the relatively high demand for
reliable communications services. The Company believes it will be well
positioned to be a leading provider of paging services in Brazil because of its
state-of-the-art infrastructure, high quality services, low cost structure and
strategic relationships.
 
    The Company has completed the buildout of the Sao Paulo system, installed
the infrastructure necessary to support its Sao Paulo operations and
substantially built out its paging system in Rio de Janeiro. The Company is
currently focused on the Initial Markets (Sao Paulo and Rio de Janeiro) and
expects to offer paging services in the Expansion Markets (Brasilia, Curitiba
and Belo Horizonte) by the first quarter of 1999. The Company currently offers
its Sao Paulo subscribers extended paging service in the other cities in the
Existing Coverage Area.
 
BUSINESS STRATEGY
 
    The Company's strategy is to become a leading provider of paging services in
Brazil. The principal elements of the Company's business strategy are to: (i)
provide high quality paging services at a low cost, (ii) leverage the PageNet
relationship, (iii) gain rapid market penetration, and (iv) provide superior
customer service.
 
    PROVIDE HIGH QUALITY PAGING SERVICES AT A LOW COST.  The Company has
employed state-of-the-art FLEX-Registered Trademark- technology developed by
Motorola, Inc. and is using equipment similar to that used by PageNet in the
United States. Furthermore, the Company utilizes a fully redundant paging system
that is linked by satellite. Management believes that as the number of
subscribers grows, this advanced technology will allow the Company to be a
provider of high quality paging services at a low cost per subscriber.
 
    LEVERAGE THE PAGENET RELATIONSHIP.  The Company is implementing a marketing
strategy and operating procedures similar to those of PageNet in the United
States, and several members of the Company's senior management have had
significant experience managing PageNet operations in the United States.
Moreover, pursuant to the Technical Services Agreement, PageNet provides the
Company with access to PageNet's products, paging expertise, intellectual
property (including the exclusive use of PageNet's tradename in Brazil), volume
supplier discounts and other capabilities. The Company also expects to benefit
from the favorable relationships that PageNet has established with suppliers of
paging equipment and from its use of the PageNet brand name, which is well
established among multinational corporations. PageNet do Brasil is PageNet's
first venture in the Latin American paging market, and PageNet's only enterprise
in Brazil. See "--Trademarks."
 
    GAIN RAPID MARKET PENETRATION.  The Company seeks to gain subscribers in its
markets rapidly through extensive marketing and advertising and competitive
pricing. Unlike competitors whose primary
 
                                       44
<PAGE>
focus has been the consumer market, the Company focuses on both business and
consumer paging customers. The Company targets business customers through a
commissioned direct sales force and through telemarketing, and will target
individual customers through advertising and through retail distribution
channels including the use of "retail showrooms" located strategically
throughout the Company's markets.
 
    PROVIDE SUPERIOR CUSTOMER SERVICE.  Management believes that its competitors
have not made customer service a primary focus of their business strategy and do
not provide the customer with service standards that are prevalent in the United
States. By focusing on key elements of customer satisfaction during the sales
process and over the life of the subscriber, the Company will provide high
levels of customer service similar to those provided by PageNet in the United
States. Moreover, similar to PageNet's practice in the United States, the
Company is introducing customer service account representatives to the paging
industry in Brazil, as a complement to sales representatives. The primary
function of customer service account representatives is to serve existing
account. In addition, customer service account representatives act as a
secondary sales force, targeting existing customers for additional services and
paging units. The Company believes this innovation will allow it to ensure
superior customer satisfaction, thereby minimizing customer turnover and
increasing subscriber base growth.
 
THE COMPANY'S MARKETS
 
    The Company has secured two licenses which enable it to broadcast paging
services on specified frequencies throughout Brazil. In addition, the Company
has secured local licenses which serve to enhance the Company's capacity in
certain cities in the Existing Coverage Area. The Company is actively marketing
paging services in Sao Paulo, plans to begin marketing paging services in Rio de
Janeiro by the first quarter of 1998 and currently offers extended paging
coverage in the remainder of the Existing Coverage Area.

    INITIAL MARKETS.  The Company has installed 44 paging transmitters in 10
cities and has recently commenced offering paging services in greater Sao Paulo,
the largest metropolitan area in the country with
 
                                       45
<PAGE>
a population of approximately 22.7 million. The Company occupies 43,000 square
feet of office space in Sao Paulo and has (i) approximately 3,500 subscribers;
(ii) installed paging transmitters in each of the nine additional cities where
it has secured licenses to broadcast paging services, including Rio de Janeiro,
(iii) hired the personnel and other infrastructure to support the Company's
operations (including its dispatch center and sales force); (iv) customized and
installed its proprietary billing/collection/inventory/ customer service
information system; (v) linked all of its paging transmitters via satellite; and
(vi) leased and designed a retail location at the Company's headquarters in the
center of Sao Paulo's business district which is scheduled to open in the second
quarter of 1997.
 
    In Rio de Janeiro, the Company has installed 12 transmitters and linked them
via satellite for immediate sale of extended coverage to Sao Paulo customers.
The Company plans to hire key local personnel, lease facilities and acquire
telephone lines from TELERJ, the state-owned telephone company in Rio de
Janeiro, beginning in the second quarter of 1997.
 
    EXPANSION MARKETS.  The Company has installed transmitters in Brasilia,
Curitiba and Belo Horizonte, and plans to develop local offices in these and
other cities as opportunities arise. The extent to which the Company will
develop local offices in any city will depend upon a number of factors,
including business and consumer demand, general economic conditions, the
presence of competing businesses and telephone infrastructure. Moreover, the
Company will consider attractive opportunities to enter other markets on an
ongoing basis.
 
    EXTENDED COVERAGE.  Extended coverage allows a paging customer to receive
pages in cities other than the customer's base city. Through the
satellite-linked transmission system, customers can choose to receive pages only
in their base city or to extend their paging service to include additional
cities. For example, a customer in Sao Paulo can still receive pages when
traveling to a city in the Extended Coverage Area. The Company has installed
transmitters in Porto Alegre, Salvador, Recife, Belem and Goiania and intends to
offer its customers in the Initial Markets and the Expansion Markets extended
paging coverage in all of these cities.
 
    Management expects that the ability to offer nationwide coverage will
increase the Company's marketability and ultimately its subscriber base. While
there is no immediate additional capital expenditure required for the provision
of nationwide service, should the Company decide to offer extended coverage in
additional cities, the Company would incur additional capital expenses in the
future for the installation of transmitters in other cities in Brazil in order
to develop a nationwide paging network. The Company expects that the incremental
cost to build a nationwide network would quickly be offset by the revenue
generated from sales of nationwide paging service in Brazil.
 
OPERATIONS AND SYSTEMS
 
    OVERVIEW.  The Company's day-to-day operations for the provision of paging
service to its subscribers are substantially similar to those of PageNet in the
United States. Pagers and other paging equipment are received by the Company and
placed in inventory, where they are appropriately labeled and coded for proper
tracking after sale, and programmed to respond only to a particular code. These
pagers are then supplied to the Company's direct sales representatives, the
Company's stores or to other sellers of the Company's service, who are
responsible for the initial sales process including up-front payment collection,
the completion of an application for service, and the delivery of a functioning
pager. The Company's billing department enters the appropriate customer
information to begin the billing process, and the collections department begins
tracking the customer's payment history to ensure timely payment. Customer
service representatives address calls from customers regarding the functions of
the pager, service details and payment policies. The dispatch center, which
receives the calls from individuals sending pages to subscribers and enters the
message into the paging terminal, dispatches messages 24 hours per day, seven
days per week. The systems department monitors daily all of the Company's
equipment including transmitters, paging terminals and supporting software and
hardware.
 
                                       46
<PAGE>
    DISPATCH CENTER.  The Company operates a state-of-the-art dispatch center,
utilizing customized dispatch software and analytic staffing software designed
to enhance productivity. The Company currently has sufficient telephone capacity
to conduct its business for the foreseeable future and expects that it will be
able to obtain additional telephone capacity as the demands of its business
require. The Company emphasizes both productivity and quality performance to its
dispatch center staff through training, monthly monitoring and incentive based
performance measures.
 
    ADVANCED INFORMATION SYSTEMS.  The Company uses an advanced proprietary
management information system, customized to accommodate the Brazilian market.
This system is used primarily to support three principal areas of the Company's
business: (i) customer service, including billing systems; (ii) network
management and operational support systems; and (iii) general business support
systems including financial management. The Company's information systems have
been designed to accommodate efficiently the increased volumes of data that the
Company expects to process in the future as the Company's subscriber base
continues to grow.
 
    CUSTOMER SERVICE.  The Company's customer information and billing system
incorporates all aspects of billing and customer preferences, which are intended
to produce a high level of customer satisfaction and to minimize customer
turnover levels. The Company's customer information and billing system provides
management with readily accessible information regarding subscribers' pager
usage, coordinates customer account information among the various departments
and ensures that customers receive all requested products and technical and
support services. This access to information facilitates the provision of
attentive customer service. The Company's account representatives, who are
responsible for customer service, respond to a customer's telephonic inquiry
within 24 hours. The Company believes that customer service is an important
factor in developing customer loyalty and differentiating its service from that
of its competitors.
 
    BILLING AND COLLECTIONS.  The Company utilizes the Brazilian custom of
invoicing customers through the banking system. Billing information is
electronically transmitted to the Company's bank which then sends the invoices
and collects the Company's receivables at its branches or affiliates. The
Company has implemented a collections policy to contact delinquent customers,
charge a late fee and finally suspend service until the account is made current.
The Company will monitor customer payment patterns and is further developing a
subscriber credit criteria policy.
 
    NETWORK MAINTENANCE.  The Company has two separate but coordinated network
maintenance systems. The first is dedicated to the proper maintenance of the
paging system which includes daily dial-in to each of the Company's paging
transmitters, monthly preventative maintenance reviews of each site, periodic
review of the satellite uplink and constant monitoring of the paging terminals
that reside in the Company's local offices. This department is also responsible
for updating and upgrading the hardware and software so that the system is
operating at the highest possible level. The second system is responsible for
the maintenance and interconnectivity of all other computer systems, including
the dispatch department's systems, the Company's LAN and related productivity
software and the telephone system. In addition, this department is responsible
for the Company's relationship with local and long distance telephone companies
including the acquisition of additional telephone lines.
 
SALES AND MARKETING
 
    The Company's current marketing strategy is to differentiate its service
from that which is available in the Brazilian market today. The Company expects
to provide service at a lower cost and with higher quality than its competitors
through the use of its advanced FLEX-Registered Trademark- technology and
satellite-linked network, customized information systems, and focus on customer
service. In its marketing and advertising, the Company will also highlight the
PageNet brand name which is associated with worldwide leadership and quality in
the paging business. The Company expects to price its high quality service
competitively and utilize various sales channels to distribute its product. The
Company will focus on both the business market and the consumer market.
 
                                       47
<PAGE>
BUSINESS MARKET
 
    CUSTOMER SEGMENTATION.  The Company plans to target businesses whose
employees are highly mobile or work at several locations. Such customers include
companies in service industries, hospitals and medical professionals,
construction and manufacturing companies, governmental agencies and retail and
financial institutions. In addition, the Company expects that the PageNet name
will be recognized by U.S.-based multinational companies giving it a competitive
advantage over other paging companies in acquiring multinational accounts.
Management believes that most major paging operators have focused on the
consumer market as opposed to the business market due to limited access to
working capital and an inability to offer the higher standard of service
demanded by business customers. The Company believes that the business market
segment will offer stronger recurring revenues and will experience a higher
subscriber retention rate than the consumer market segment. The Company
estimates that, as of December 31, 1996, businesses accounted for approximately
30% of total pagers in service in Brazil.
 
    Subject to appropriate credit policies, the Company plans to lease pagers to
businesses, thereby reducing the business customer's capital outlay and
increasing the Company's revenue per unit. The Company has identified more than
20,000 business targets for sales in its early months and generally expects that
businesses will account for approximately 40% to 50% of the total units in
service in Brazil.
 
    DISTRIBUTION.  The Company employs a direct sales force to target specific
businesses. Sales representatives receive leads through a number of sources,
including the Company's telemarketing department, referrals and advertising. In
addition, unlike its competitors, the Company employs a separate team of account
representatives, whose primary function is to serve existing accounts. In
addition, the account representatives act as a secondary sales force, targeting
existing customers for additional services and paging units. The Company
believes that by shifting the customer service function from the sales
representative to an account representative, the sales representative is more
productive and the customer is better served.
 
CONSUMER MARKET
 
    CUSTOMER SEGMENTATION.  The Company estimates that, as of December 31, 1996,
individuals accounted for approximately 70% of total pagers in service in
Brazil. Management believes that consumer demand for paging service arises from
four factors: (i) the increased consumer purchasing power due to Brazil's stable
and growing economy; (ii) the need for reliable, portable communications
services; (iii) delayed access to telephone service or the prohibitive cost of
immediate access; and (iv) the higher cost and lower reliability of cellular
telephone service.
 
    Advertising is a key component of the Company's consumer marketing strategy.
To that end, management has hired P/P Asociados, an advertising firm with
extensive experience in consumer products, which was awarded the TOP Marketing
in Retail Award in 1995. The Company's initial advertising campaign will be
followed by an advertising maintenance program, both of which will include the
use of newspapers, magazines, billboards and radio.
 
    DISTRIBUTION.  In Sao Paulo, the Company's advertising campaign will direct
consumers to the Company's retail showrooms that will be located strategically
throughout the area. Additionally, the Company is developing a retail outlet
distribution channel through which the Company may provide pagers to the
retailer at wholesale prices. Once purchased by a subscriber, the pager is
activated on the Company's standard retail contract as a subscriber-owned pager.
The Company may also distribute indirectly under marketing agreements with
unrelated marketing organizations, or "resellers," as developed by PageNet in
the United States. Typically, in the United States, the paging company offers
resellers paging services in bulk quantities at a wholesale monthly rate that is
lower than the regular retail rates, and the resellers endeavor to resell the
paging services to subscribers for a higher price. In the United States, because
resellers bear the economic burden of pager capital investment, direct selling
expense and certain administrative costs including billing for paging service,
collections and customer service, the reseller network has been a very
attractive distribution channel. Management is in discussions with retailers and
 
                                       48
<PAGE>
resellers regarding adapting these methods for the Brazilian market; however,
there can be no assurance that either of these distribution channels will ever
be used.
 
PRODUCTS
 
    INITIAL PRODUCTS.  Initially, the Company will offer PIN-based alphanumeric
paging with dispatch service included, at a competitive price. Additional
product enhancements will be available to subscribers, including extended
coverage in Rio de Janeiro, pager protection against loss or theft and pager
maintenance.
 
    SUBSEQUENT PRODUCTS.  Within the first year of operation, the Company
expects to offer additional products, many of which will be new products to the
Brazilian paging market. These products are expected to include: (i)
page-by-name, which allows the caller to eliminate the use of a PIN and send a
page using only the subscriber's name; (ii) direct dial paging, which allows the
caller to dispense with the use of a PIN and send a page using a subscriber's
direct telephone number; (iii) customized greeting, which allows a subscriber to
customize service and have a dispatch center operator answer using the
subscriber's name and other information as designated by the subscriber; (iv)
numeric paging; (v) PageMail, which adds voice mail service to an existing
subscriber account; (vi) click detection, which enables Brazil's prevalent pulse
telephones to send pages where tone telephones would otherwise be required; and
(vii) self dispatch, which allows subscribers to send pages directly from their
personal computers, without accessing the dispatch center. Although the
Company's current principal focus is offering its initial products at
competitive prices and achieving rapid market penetration, the Company
anticipates that these additional products may enhance revenues and attract more
technologically demanding customers when and if such subscriber products are
implemented and offered.
 
    FUTURE PRODUCTS.  In the future, the Company may deploy new paging or
paging-related products. One such product in an advanced development stage is
VoiceNow. Developed jointly by PageNet and Motorola, Inc., VoiceNow subscribers
would carry a portable receiver, approximately the same size as an alphanumeric
pager, that is capable of receiving, storing and playing brief voice messages.
Although the Company has access to this and additional technologies through its
relationship with PageNet, there can be no assurance that the Company will offer
any of these products or services in the future.
 
PAGING SYSTEMS EQUIPMENT
 
    The Company's paging system equipment consists of call distribution
telephone connectors, dispatch systems, paging terminals, satellite uplinks,
satellite receivers, paging transmitters and pagers. Additional supporting
equipment includes fully redundant telephone switches, dispatch systems and
paging terminals, uninterrupted power supplies, backup generators, dedicated
land lines redundant to the microwave and satellite-linked systems and land
lines to each transmitter for daily diagnostic review and maintenance. The
Company, with the technical support of PageNet, has supervised the entire paging
infrastructure buildout from transmitter site selection to transmitter
installation alignment to programming of the paging terminal.
 
                                       49
<PAGE>
    The Company has secured satellite access from Embratel Sistema Telebras, the
Brazilian state-owned satellite and long distance telephone company, to access
BrasilSat One, a Brazilian satellite, and link its paging transmitters. The
Company leases its satellite access under a five-year contract. A "backbone"
network of satellite paths with microwave and conventional radio links will
connect the operators, telephone lines, terminals and control equipment to
various cities to be served.
 
    The equipment used in the Company's paging operations is available for
purchase from more than one source and the Company anticipates that equipment
and pagers will continue to be available to the Company in the foreseeable
future, consistent with normal manufacturing and delivery lead times. Because of
the high degree of compatibility among different models of transmitters,
computers and other paging equipment manufactured by suppliers, the Company has
designed its systems without being dependent upon any single source of such
equipment.
 
    The Company does not and will not manufacture any of the pagers or related
transmitting and computerized paging terminal equipment used in the Company's
paging operations. The Company's relationship with PageNet provides it with
access to volume discounts on all of its supplies. PageNet has arranged with its
U.S. suppliers to ensure that the Company will receive favorable prices on all
supplies, including pagers. There can be no assurance that PageNet's arrangement
with its suppliers will continue or that the Company will be able to receive all
of its supplies at prices comparable to those obtained by PageNet.
 
COMPETITION
 
    The Company does experience and will continue to experience direct
competition from one or more competitors in all the locations in which it plans
to operate. Competition for subscribers to the Company's paging services in most
geographic markets will be based primarily on price, quality of services offered
and the geographic area covered. The Company believes that its price, quality of
its services and its geographic coverage areas will generally compare favorably
with those of its competitors.
 
    Although some of the Company's competitors are small privately owned
companies serving only one market area, others are subsidiaries or divisions of
larger companies that provide paging services in multiple market areas. Among
the Company's competitors are Teletrim, Mobitel, Conectel, Powernet and Intelco.
 
    In the Sao Paulo and Rio de Janeiro metropolitan areas, which together are
estimated to represent approximately 67% of the current paging market in Brazil,
more than eight competitors share a market of approximately 540,000 pagers.
While there is healthy competition in the paging market, no single competitor
dominates the market. The current industry leaders, Teletrim and Mobitel, each
service fewer than 200,000 subscribers. In Sao Paulo, the Company's main
competitors will be Teletrim, which holds approximately 25% of the market, and
Mobitel, which holds approximately 20% of the market. In Rio de Janeiro,
Teletrim holds approximately 44% of the market while Mobitel and Powernet hold
approximately 18% and 14%, respectively. In the regions of Brazil outside of Sao
Paulo and Rio de Janeiro, which account for approximately 33% of the existing
paging market in Brazil, Mobitel leads the major operators, primarily due to its
strong presence in Brasilia. Approximately 65% of the market outside of Sao
Paulo and Rio de Janeiro is held by smaller paging operators.
 
    The primary focus of the Company's competitors in the Brazilian paging
market has been the consumer market, rather than the business market. Management
believes that the corporate customer in the business markets will be more likely
to maintain service, remit payments on a timely basis, purchase enhanced
services and have a better appreciation for the paging service. The Company
believes that it will be able to maintain a lower than average churn rate due to
the high quality of its service and its emphasis on the corporate customer and
business accounts.

EMPLOYEES
 
    As of April 30, 1997, the Company had a total of 138 employees. The
Company's employees are not currently subject to collective bargaining
agreements, although under the Brazilian Constitution the employees have a right
to organize a union. The Company considers its employee relations to be good.
The Company anticipates that it will employ approximately 300 people by the end
of 1997 as a result of the launch of Sao Paulo operations.
 
GOVERNMENT REGULATION
 
    TELECOMMUNICATIONS.  Under Brazilian law, the provision of public services
requires a concession, license or authorization granted by the relevant
governmental authority. Under the Brazilian Constitution, the Federal Government
is required to provide, directly or through concession, license or
authorization, telecommunication services in accordance with the applicable
regulations. According to this Constitutional provision, the Federal Government
may freely grant concessions to private sector companies to provide telephone
and telecommunications services and data transmission services. On July 19,
1996, Law 9,295 was enacted to regulate telecommunication services, which
includes a provision establishing that the Federal Government may impose
restrictions in the composition of the capital stock of the companies holding
concessions for the provision of mobile cellular telephone services and
satellite signal transportation services for the period of three years following
the enactment of such law. Such restriction will be imposed when required by
national interest and shall require that at least 51% of the voting capital of
such companies is held by Brazilian citizens. It is also provided by such law
that the concessions can only be granted to companies organized under Brazilian
law and having their head offices in Brazil. Decree 2,056 of November 4, 1996,
which approved the regulations applicable to cellular telephone services,
delegated to the Ministry of Communications the authority to establish limits to
foreign participation with respect to such services. The Ministry of
Communication has issued the call for a public bid (Concorrencia 001/96-SFO/MC)
for the purchase of concessions to provide cellular telephone services, with the
requirement that at least 51% of the voting capital of the proposed owners of
the concessions be held by Brazilian citizens. Brazil was divided into 10
concession areas and the interested companies presented their bids on April 7,
1997. The awarding of the concessions will be made in stages of two concession
areas at a time, with all concessions expected to be granted by early 1998. The
city of Sao Paulo and surrounding municipalities are included in the first group
of concessions.
 
    A bill of the General Telecommunications Law was submitted to Congress by
the Federal Government in December 1996, and is designed to eventually replace
the current Telecommunications Code enacted in 1962. The bill focuses on the
following matters: (i) creation of a telecommunication regulatory agency, (ii)
privatization of the Telebras System, and (iii) organization of the
telecommunications system, including the grant of licenses. The bill as
currently drafted permits the Federal Government, under certain conditions, to
impose foreign ownership restrictions relating to the capital stock of companies
providing telecommunications services.
 
    DEVELOPMENT OF PAGING REGULATIONS.  The Ministry of Communications is the
governmental body responsible for the granting of paging licenses in Brazil and
is also the body in charge of regulating the exploitation of such services in
Brazil. Currently, there are four Ordinances, the first of which was enacted by
the Ministry of Infrastructure and the other three of which were enacted by the
Ministry of Communications, that regulate paging services: (i) Ordinance No.
232, of October 23, 1991, which establishes the principles applicable to the
exploitation of paging services; (ii) Ordinance No. 257, of October 23, 1991,
which establishes complementary conditions and procedures applicable to the
exploitation of paging services, as well as the guidelines for public bids and
analysis of related proposals; (iii) Ordinance No. 579, of August 2, 1994, which
created the modality of restricted national exploitation; and (iv) Ordinance No.
1306, of November 29, 1996, which establishes the conditions for the use of the
frequencies by paging services.
 
                                       51
<PAGE>
    Pursuant to paging regulations, a paging operator must first obtain a paging
license from the Ministry of Communications in order to provide paging services
in Brazil. All licenses are non-exclusive licenses to provide paging services in
a service area.
 
    The paging regulations distinguish between local, national and nationwide
restricted paging licenses. Local paging licenses allow the license holder to
provide separate paging services in one or more localities, in accordance with
the service area indicated therein. National licenses require the license holder
to, within the first year from the date of issuance of the license, provide
service in three states and within ten years, provide services in a minimum of
10 states. Pursuant to the terms of Ordinance No. 579, a license holder may
request that the Ministry of Communications transform its local licenses into a
nationwide restricted license, which allows for the provision of integrated
services, if such license holder is providing services in at least 12 localities
in at least six different Brazilian States and its system is capable of
simultaneous or sequential operation. Once the license holder has been granted a
nationwide restricted license, it may utilize its frequency nationwide, except
in localities where the frequency was previously given to a local license
holder.
 
    On April 8, 1997, the President enacted Decree No. 2196, approving the
Regulation for Special Telecommunication Services, within which paging services
are included. Such Decree provides the guidelines for the granting of licenses
with respect to such services by the Ministry of Communications. Such Decree
confirmed the competence of the Ministry of Communications to establish specific
complementary rules, to grant licenses, to allocate frequencies and to supervise
the exploitation of such special services.
 
    Decree No. 2196/7 regulates the procedure for the granting of new licenses
for exploitation of special services, which include the possibility of a prior
public consultation by the Ministry of Communications with respect to the
granting of such licenses, as well as the applicable terms and conditions of
such grants. The Decree also regulates the requirements of the call for public
bid, the rules for pre qualification of the interested parties, the criteria for
judgment of the proposals and for the granting of the licenses. The granting of
new licenses shall be formalized by means of the execution of a contract between
the Ministry of Communications and the awarded party.
 
    Regarding the exploitation of the services the Decree expressly assures the
licensees the right to use equipment not owned by the licensee and to contract
with third parties the development of activities inherent, accessory or
complementary to the licensed services, provided that: (a) the licensee shall
remain responsible before the Ministry of Communications and the users for the
execution and exploitation of the services; and (b) the licensee shall be
contractually bound to the users.
 
    Furthermore, Decree No. 2196/97 specifically provides that the Ministry of
Communications shall issue complementary regulations regarding each of the
modalities of Special Telecommunication Services, which shall regulate the
specific conditions for the exploitation of the services, including: technical
characteristics, rights and obligations of the licensee and of the users,
conditions for interconnection of networks, expansion of the services and use of
the public network, as well as conditions regarding the use of frequencies,
prices and tariffs.
 
    Decree No. 2196/97 assures the transfer of the licenses, provided the
transferee complies with the qualification requirements imposed by the Ministry
of Communications and undertakes to comply with all of the conditions of the
contract, assuming all rights and obligations of the transferor. However the
minimum term for transfer of the licenses shall be established by the
complementary regulations referred above.
 
    The number of requests for paging licenses presented to the Ministry of
Communications increased in 1994 and 1995 and, as of March 14, 1997,
approximately 855 local licenses had been issued. The Ministry of Communications
has estimated that another 1,000 local licenses will be issued in the near
future. In April 1997, two of the Licenseholders (TVA and Multiponto) were
granted nationwide restricted licenses by the Ministry of Communications. As of
May 1997, only twelve national licenses were issued by the Ministry of
Communications.
 
                                       52
<PAGE>
    PAGING LICENSES.  Under Ordinance No. 232/91, paging licenses are granted by
the Ministry of Communications for a period of 15 years and are renewable for
successive 15 year periods. The nationwide restricted licenses which, under the
terms of Ordinance No. 579/94 result from the aggregation of local licenses are
granted by the Ministry of Communications for a period of ten years, regardless
of the remaining term of the original local licenses. Under Decree No. 2196/97,
the original license terms are assured, but renewal terms may vary from 10 to 15
years as established in complementary regulations still to be issued. Renewal of
the license by the Ministry of Communications is expected provided the paging
operator has complied with the terms of the operating license and has requested
the renewal at least 18 months prior to the expiration date of the license.
Under the Decree a fee may be charged for the renewal of the license in an
amount to be agreed between the Ministry of Communications and the licensee, at
least 12 months prior to the expiration of original term. The license
establishes the terms and conditions under which the paging service should be
provided. Those conditions include, among others: (i) lack of exclusivity of the
service, (ii) a prohibition on the transfer of the license during the first
three years, commencing from the date of issuance of the operating license,
(iii) prior authorization from the Ministry of Communications for any transfer
of the license, (iv) the licensee's compliance with certain terms and conditions
specified by the Ministry of Communications such as price schedules, and (v) the
licensee's performance under the license. Any transfer of a paging license is
subject to the prior approval of the Ministry of Communications. A license may
not be directly transferred by a license holder to a third party until after the
expiration of the three year waiting period. Transfers of shares which cause a
change in the control of the licensee or entity which controls the licensee must
also receive prior approval of the Ministry of Communications. Licenses may be
revoked prior to their expiration by the Ministry of Communications for a number
of reasons, including: (i) the public interest as determined by the Ministry of
Communications, (ii) the failure of the licensee to meet the terms and
conditions of the license, (iii) the transfer of the license without the consent
of the Ministry of Communications, or (iv) the failure of the licensee to pay
the required license fees. To initiate paging services, the paging operator must
be granted three different permits or approvals by the Ministry of
Communications: (i) the initial license, granted in the form of a ministerial
ordinance which entitles the license holder to develop paging services under a
certain frequency and in certain localities; (ii) the Project Approval
Certificate which permits installation of equipment necessary for the
development of the paging service in accordance with the installation project of
the license holder and, once the installation period is complete, (iii) the
paging operating license. Under applicable regulations, the Licenseholders
received paging licenses from the Ministry of Communications and pursuant to the
Operating Agreements and other covenants (the "Operating Agreements"), the
Company is required to construct and start the operation of its service within
12 months of the issuance of the paging license. To meet the requirements of
operating within the meaning of the paging license, a licensee is required to
construct a single site from which a radio signal can be directed. The Company
has complied with this condition in each of the cities for which a local paging
license and a Project Approval Certificate have been obtained and, as a result,
the corresponding paging operating permit for each of such cities has been
issued by the Ministry of Communications. Under the recently obtained nationwide
restricted licenses, it will be necessary for the Company to present and obtain
approval from the Ministry of Communications of the installation project, as
well as, the subsequent issuance of the paging operating license for the
relevant station. The fee for an operating license totals one-half of one
percent of the fixed assets of the licensee (deemed to be the transmitters,
paging terminal and initial supply of pagers). In addition, licensees must pay a
fee of approximately US$57 per transmitter installed.
 
    Subject to certain exceptions, generally any paging licenses not already
issued are to be granted pursuant to a public auction administered by the
Ministry of Communications. The rules of the auction are expected to be open to
public comment before the actual process is initiated. The Company is planning
to participate in this auction although there can be no assurance that the
Company will acquire any licenses at the auction.
 
    Additional frequencies have been awarded to Mobitel in Sao Paulo and Rio de
Janeiro, and to Teletrim in Rio de Janeiro. The Company believes that as the
market for pagers grows, the Ministry of
 
                                       53
<PAGE>
Communications will amend current regulations allowing the Company to receive
additional frequency allocations if needed. The Company anticipates needing
additional licenses in the Initial Markets only. There can be no assurance that
the Company will receive the additional licenses, which may materially alter the
Company's market projections.
 
    PAGING LICENSE OWNERSHIP; OPERATING AGREEMENTS; AGREEMENTS TO TRANSFER
LICENSES.  The licenses presently operated by the Company were granted to and
are owned by TVA, Multiponto and San Francisco Comunicacoes Ltda., an affiliate
of IVP (the "Licenseholders"). The Company has entered into Operating Agreements
with each of the Licenseholders pursuant to which the Company has the right to
operate the paging licenses held by the Licenseholders. The Company has also
entered into Agreements of Promise of Assignment and Transfer of Permissions
(the "Transfer Agreement") with each Licenseholder pursuant to which the
Licenseholders have agreed, subject to the necessary approvals, to transfer
their paging licenses to the Company after the three year period established by
Brazilian law, during which such licenses are not allowed to be transferred, or
on such earlier date as may be permitted by Brazilian law. Under the applicable
paging legislation, operating agreements are permitted and do not amount to a
transfer of the license. See "Risk Factors--Risk Factors Relating to the Company
and the Notes--Government Regulations" and "Certain Transactions--Formation
Transactions."
 
TRADEMARKS
 
    The Company markets its paging and related services under various names and
marks, including PageNet and PageMail. The Company's use of each of these marks
is granted by the terms of the Technical Services Agreement with PageNet. Under
the Technical Services Agreement, the Company has use of the PageNet trademarks
and service marks in Brazil for so long as PageNet holds such properties absent
breach by the Company of its obligations thereunder or Brazilian governmental
action requiring its termination. PageNet has applied to register the mark
PageNet in Brazil. PageNet has advised the Company that certain third parties
also have applied to register the PageNet name in Brazil. PageNet intends to
pursue vigorously its registration of the PageNet mark. However, there can be no
assurance that PageNet will be successful in which case the Company may not have
the right to use the PageNet mark. See "Certain Transactions--Formation
Transactions."
 
LEGAL PROCEEDINGS
 
    The Company is not a party to any legal proceedings that would have a
material adverse effect on its results of operations and financial condition.
 
PROPERTIES
 
    The Company currently leases 43,000 square feet of office space in Sao Paulo
under a five-year lease. This space houses the Company's corporate headquarters
as well as its Sao Paulo operation, including its dispatch center, systems room
and a retail showroom. In addition, the Company expects to lease an additional
retail showroom in downtown Sao Paulo.
 
    In each of the cities in which the Company has secured paging licenses, the
Company has entered into and will continue to enter into agreements for the
placement, construction and maintenance of paging transmitter antennas.

Trynin and Fregenal resided in the United States prior to joining the Company,
each employment agreement also provides for additional compensation as a result
of their relocation ("relocation compensation"), including a foreign service
incentive equal to 10% of the base salary, a goods and services allowance to
cover cost of living adjustments and a foreign housing allowance. If the Company
terminates the Executive without "just cause" or if the Executive resigns for
"good reason" (in each case as defined in the employment agreement), the
Executive shall be entitled to receive an additional 12 months' base salary and
the relocation compensation for a period of 45 days following the termination of
employment. The initial term of each employment agreement is two years, which
will be automatically extended for one additional period of two years, unless
the Company or the Executive provides the other with a notice of termination at
least three months prior to the expiration of the initial term. The employment
agreements also include customary non-competition and confidentiality
provisions. Also pursuant to the employment agreement, Warburg Pincus has
granted the Executive certain "tag-along" rights in the event that Warburg
Pincus sells or otherwise disposes of a majority of its shares of Common Stock.
Upon execution of their respective employment agreements, Mr. Trynin was granted
17,603 shares of Common Stock and Mr. Fregenal was granted 13,202 shares of
Common Stock. These shares of Common Stock are subject to forfeiture in the
event the Executive's employment is terminated by the Company for "just cause"
or by the Executive other than for "good reason" before such Executive has
completed five years of employment, with 100%, 80%, 60%, 40% and 20% of the
shares subject to forfeiture if the employment is terminated during the first,
second, third, fourth and fifth years of employment, respectively.
 
SHARES OF COMMON STOCK RESERVED FOR MANAGEMENT
 
    In addition to the shares already issued to Messrs. Trynin and Fregenal, the
Company has reserved 101,340 shares of Common Stock for issuance to members of
the Company's management at the discretion of the Board of Directors. Such
shares may be issued pursuant to a stock option plan adopted by the Company or
directly to management members, in either case subject to vesting or forfeiture
provisions as determined by the Board of Directors.

                              CERTAIN TRANSACTIONS
 
FORMATION TRANSACTIONS
 
    In connection with its formation, the Company has been a party to the
following transactions with its executive officers, directors and five percent
shareholders:
 
    In December 1996, the Company entered into a Securities Subscription
Agreement with PageNet NV, Warburg Pincus, IVP Cayman, Multiponto and TVA
pursuant to which, among other things, the Company issued shares of Common
Stock, Preferred Stock and subscription bonds to purchase Common Stock. The
Company believes that the terms of the Securities Subscription Agreement were
negotiated at arm's-length by the initial investors in the Company. In
connection with the formation of the Company, the Company granted registration
rights to Warburg Pincus, IVP Cayman, PageNet NV, Multiponto and TVA with
respect to all shares of Common Stock and Preferred Stock owned by them. See
"Principal Shareholders-- Registration Rights Agreement."
 
    In December 1996, the Company and PageNet entered into a Technical Services
Agreement pursuant to which PageNet will provide technical services and support,
including (i) assistance with the conversion and construction of the Company's
paging infrastructure; (ii) access to the PageNet personnel and management
supervision to assist the Company in providing paging services; (iii) training
of key members of the Company's management; (iv) making available on an
exclusive basis in Brazil, technology, software, new product development, and
system design; and (v) interfacing with vendors to seek favorable prices and
services, comparable to those obtained by PageNet. In addition, pursuant to the
terms of the Technical Services Agreement, PageNet granted to the Company, among
other things, an exclusive, royalty-free license (the "Intellectual Property
License") to use the trademarks PageNet and VoiceNow and the tradename Paging
Network in connection with the Company's advertisement, promotion, marketing,
sale, development, and provision of telecommunications services in Brazil.
Subject to certain rights to sublicense, the Intellectual Property License is
non-transferable. In consideration of the performance of PageNet's obligations
under the Technical Services Agreement, the Company has granted PageNet NV the
right (in the form of subscription bonds) to purchase 325,982 shares of the
Common Stock at an exercise price of approximately US$.025 per share (after
giving effect to the Common Stock Split). The initial term of the Technical
Services Agreement is five years. The initial term will be extended for
successive three-year terms unless either party gives notice of its intent not
to so extend at least one year prior to the end of the then current term.
PageNet may, however, terminate the agreement (i) six months after it ceases to
beneficially own at least five percent of the Common Stock outstanding on a
fully diluted basis including the subscription bonds to purchase such Common
Stock or (ii) if any entity other than Warburg Pincus owns 50% or more of the
Common Stock outstanding on a fully diluted basis including the subscription
bonds to purchase such Common Stock. The Intellectual Property License will
survive the termination of the Technical Services Agreement absent breach by the
Company of its obligations thereunder or if Brazilian governmental action
requires a termination of the Intellectual Property License. In the event the
Intellectual Property License is terminated, PageNet will not, for a period of
two years from such termination, use the trademarks PageNet or VoiceNow in
Brazil for Licensed Services (as defined in the Intellectual Property License).
In addition, the Company is subject to certain performance standards and other
obligations, the non-compliance with which permit PageNet to terminate the
Technical Services Agreement (including the Intellectual Property License). The
Company believes that the Technical Services Agreement was negotiated at
arm's-length by the initial investors in the Company. See "Risk Factors--Risk
Factors Relating to the Company and the Offering--Dependence on PageNet
Technical Services and Support."
 
    In December 1996, the Company entered into Operating Agreements with each of
the Licenseholders pursuant to which the Licenseholders have granted the Company
the exclusive right to resell paging services utilizing the paging licenses held
by the Licenseholders (the "Licenses"). The Company and each Licenseholder have
also entered into Transfer Agreements, pursuant to which the Licenseholders have
 
                                       59
<PAGE>
agreed to transfer the Licenses to the Company following the three year waiting
period mandated by Brazilian law or on such earlier date as may be permitted by
Brazilian law. In consideration of the performance by each Licenseholder of its
obligations under such agreements and after giving effect to the Common Stock
Split, the Company has (i) issued and sold to IVP Cayman 325,982 shares of the
Common Stock for a purchase price of approximately US$.025 per share, (ii)
issued and sold to Multiponto 81,495 shares of the Common Stock for a purchase
price of approximately US$.025 per share and has granted Multiponto the right
(in the form of subscription bonds) to purchase up to 40,748 shares of Common
Stock at a price of approximately US$.025 per share and (iii) has granted TVA
the right (in the form of subscription bonds) to purchase up to 40,748 shares of
Common Stock at a price of US$.025 per share. The Company believes that the
Operating Agreements and the Transfer Agreements were negotiated at arm's-length
by the initial investors in the Company. Given that certain acts or omissions by
a Licenseholder could result in the revocation of its paging licenses or
unavailability of such licenses to the Company, the Licenseholders have agreed
to several covenants in the Operating Agreements designed to limit such risk to
the Company. See "Risk Factors--Risk Factors Relating to the Company and the
Offering--Regulation and Ownership of Licenses." and "Business--Government
Regulation--Paging License Ownership; Operating Agreements; Agreements to
Transfer Licenses."
 
RESTRUCTURING TRANSACTIONS
 
    In connection with the sale of the Old Notes, Warburg Pincus contributed all
shares of Common Stock directly owned by it to Holding LLC in exchange for 100%
of the voting member interests in Holding LLC. In addition, pursuant to a
subscription agreement (the "Subscription Agreement") with the Company, Holding
LLC purchased shares of Common Stock equivalent to 7.0% of the Common Stock on a
fully diluted basis for the capital accounts of the holders of non-voting member
interests in Holding LCC (such transactions collectively referred to as the
"Restructuring").
 
    The Subscription Agreement imposes a number of covenants on the Company for
the benefit of Holding LLC, including (i) providing certain financial
information concerning the Company and its subsidiaries that Holding LLC is
required to provide to its Members, (ii) subject to debt instruments to which
the Company is a party, distributing cash to Holding LLC in an amount that is
intended to approximate the Members' U.S. federal income tax liability on the
net income allocated to the Members for U.S. federal income tax purposes by
Holding LLC (but there can be no assurance that such amount will be sufficient
in all cases to discharge such tax liabilities), (iii) creating a sponsored
American Depositary Receipt program for the Common Stock that will be in effect
on or prior to the occurrence of a Liquidation Event (as defined in the
Subscription Agreement) and (iv) notifying Holding LLC at the appropriate time
that there is no material likelihood that PageNet do Brasil should be considered
a "passive foreign investment company" for U.S. federal income tax purposes for
its current or any future taxable year. The Company believes that the
Restructuring was negotiated at arm's-length with Holding LLC.
 
    All future transactions between the Company and its officers, directors,
principal shareholders or their respective affiliates, will be on terms no less
favorable to the Company than can be obtained from unaffiliated third parties.

SHAREHOLDERS AGREEMENT
 
    The relations among the Company's shareholders, Warburg Pincus, PageNet NV,
IVP Cayman, Multiponto, TVA (together, the "Shareholders") and Messrs. Trynin
and Fregenal (together with other stockholding members of the Company's
management "Management Investors"), are governed by a Shareholders Agreement,
dated as of December 11, 1996, as amended as of March 10, 1997 (the
"Shareholders Agreement"). The following describes certain terms of the
Shareholders Agreement:
 
    BOARD OF DIRECTORS.  The Company is managed by a Board of Directors that is
currently comprised of five members. For so long as IVP Cayman beneficially owns
at least 10% of the Common Stock outstanding on a fully diluted basis, IVP
Cayman will have the right to designate one director to the Board of Directors.
For so long as (i) PageNet NV beneficially owns at least 10% of the Common Stock
outstanding on a fully diluted basis or (ii) the Technical Services Agreement is
in full force and effect, PageNet NV shall have the right to designate one
director to the Board of Directors. For so long as Warburg Pincus beneficially
owns more shares of Common Stock outstanding on a fully diluted basis than any
other shareholder of the Company, Warburg Pincus will have the right if it so
chooses to designate a majority of the directors of the Board of Directors. In
the event Warburg Pincus is not entitled to designate a majority of the Board of
Directors, but Warburg Pincus beneficially owns at least 10% of the Common Stock
outstanding on a fully diluted basis, Warburg Pincus will have the right to
designate one director to the Board of Directors.
 
    RESTRICTIONS ON TRANSFER OF STOCK.  Neither IVP Cayman nor PageNet NV will
sell, assign, transfer or otherwise dispose of ("Transfer") any capital stock of
the Company ("Capital Stock") held by it without the prior written approval of
Warburg Pincus, which approval will not be unreasonably withheld. Such
restriction applies to IVP Cayman only for a period of five years following the
issuance of any such stock. The Management Investors may not Transfer stock held
by them for a period of five years following the issuance of such stock, subject
to certain exceptions.
 
    PAGENET NV RIGHT OF FIRST OFFER.  PageNet NV has a right of first offer with
respect to either the Transfer by any Shareholder or the Transfer by the Company
of any of its assets.
 
    TAG-ALONG RIGHTS; DRAG-ALONG RIGHTS.  The Shareholders Agreement provides
tag-along rights for (i) the Management Investors in the event that the
Shareholders Transfer all their shares of Common Stock and (ii) each Investor in
the event that another Shareholder Transfers any of its Capital Stock. In the
event that Warburg Pincus chooses to Transfer all its shares of Common Stock or
Preferred Stock to a proposed transferee, the Shareholders Agreement provides
that Warburg Pincus may require each other Shareholder to Transfer all its
shares of Common Stock or Preferred Stock, as the case may be, to such
transferee.
 
    PREEMPTIVE RIGHTS.  Except in connection with an underwritten public
offering or a merger of the Company, the Shareholders Agreement provides each
Shareholder with preemptive rights in connection with any issuance of equity
securities by the Company. Each Shareholder has agreed to waive its preemptive
rights in connection with the issuance of shares of Common Stock to Holding LLC.
 
    CONSENT RIGHTS OF PREFERRED STOCK.  The consent of the holders of a majority
in interest of the outstanding Preferred Stock is required for any of the
following actions to be taken by the Company: (i) the acquisition or disposition
of significant assets outside the ordinary course of business, (ii) the
incurrence of any indebtedness or other commitment in excess of US$250,000,
(iii) the amendment of the by-laws (ESTATUTOS SOCIAIS) of the Company (the
"By-laws"), (iv) the guarantee of any third party indebtedness or the incurrence
of any lien outside the ordinary course of business, (v) transactions with
affiliates, (vi) the entry by the Company into a new business, (vii) the
issuance of any equity securities, and (viii) the winding up, liquidation or
dissolution of the Company. The consent rights of the holders of the Preferred
 
                                       62
<PAGE>
Stock with respect to the matters described in clauses (i) through (vi) above
will not be required in the event that Warburg Pincus ceases to beneficially own
any shares of Preferred Stock.
 
REGISTRATION RIGHTS AGREEMENT
 
    In connection with the formation of the Company, the Company entered into a
Registration Rights Agreement with the Shareholders (the "Registration Rights
Agreement"), pursuant to which the Company granted registration rights with
respect to all shares of Common Stock and Preferred Stock owned by the
Shareholders. Such registration rights also extend to any capital stock of the
Company issued as a dividend in respect of such shares. Subject to certain
customary exceptions and limitations, the Company has agreed to provide two
demand registrations to the holders of Registrable Securities (as defined in the
Registration Rights Agreement), which may be exercised by the holders of more
than 50% of the Registrable Securities. The Registration Rights Agreement also
provides for piggyback registration rights in the event the Company files a
registration statement for the sale of its securities, subject to certain
customary exceptions and limitations. In addition, once the Company is qualified
to use Form F-3 or S-3 under the Securities Act, the holders of Registrable
Securities shall have the right to request four registrations on Form F-3 or S-3
to register all or a portion of such shares under the Securities Act, subject to
certain conditions. In general, all fees, costs and expenses of such
registration (other than underwriting discounts and selling commissions
applicable to sales of the Registrable Securities) will be borne by the Company.
The Company has agreed to indemnify the holders of Registrable Securities from
any liability arising out of or relating to any untrue statement of a material
fact or any omission of a material fact in any registration statement or
prospectus filed by the Company pursuant to the Registration Rights Agreement,
subject to certain exceptions.

<PAGE>
                            DESCRIPTION OF THE NOTES
 
    The Old Notes were issued and the New Notes are issued under an Indenture
dated as of June 1, 1997 between Paging Network do Brasil S.A. (the "Company")
and The Chase Manhattan Bank, as trustee (the "Trustee"), a copy of which is
available upon request to the Company. The terms of the New Notes are identical
in all material respects to the terms of the Old Notes, except for certain
transfer restrictions and registration rights relating to the Old Notes and
except that if the Exchange Offer is not consummated by November 3, 1997, the
interest rate borne by the Old Notes will increase by 0.50% per annum for the
first 90-day period following November 3, 1997 and will increase by an
additional 0.50% per annum with respect to each subsequent 45-day period up to a
maximum amount of 2.00% per annum. The following summary of certain provisions
of the Indenture does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, the Trust Indenture Act of 1939 and
to all of the provisions of the Indenture, including the definitions of certain
terms therein and those terms made a part of the Indenture by reference to the
Trust Indenture Act, as in effect on the date of the Indenture, and to the Trust
Indenture Act, in the case of the Exchange Notes, if any, or the effectiveness
of a Notes Shelf Registration Statement. Whenever particular provisions or
definitions of the Indenture, the Notes or the terms defined therein are
referred to herein, such provisions or definitions are incorporated herein by
reference. The definitions of certain capitalized terms used in the following
summary are set forth below under "--Certain Definitions."
 
    Remaining Old Notes still outstanding after the consummation of the Exchange
Offer and New Notes issued in connection with the Exchange Offer will be treated
as a single class of securities under the Indenture.
 
GENERAL
 
    The Notes will be issued only in registered form, without coupons, in
denominations of US$1,000 and integral multiples of US$1,000. See "Book-Entry;
Delivery and Form." The Company has appointed The Chase Manhattan Bank to serve
as Registrar, Co-Paying Agent and Trustee under the Indenture at its offices at
450 West 33rd Street, New York, New York 10001 and Chase Trust Company ("Chase
Japan") to serve as Principal Paying Agent under the Indenture at its offices at
2-1, Marunouchi 1-chome, Chiyoda-ku, Tokyo 100, Japan. The Trustee, the
Registrar, the Company and the Principal Paying Agent are responsible for, among
other things, (i) maintaining a record of the registration of ownership,
exchange and transfer of the Notes and accepting Notes for exchange and
transfer, (ii) ensuring that payments of the principal and interest received
from the Company or any Guarantor in respect of the Notes are duly paid to the
registered holders thereof, (iii) transmitting to the Company any notices or
other communications from holders of Notes and (iv) transmitting to the holders
of Notes notice of the occurrence of any Default after obtaining knowledge
thereof. No service charge will be made for any registration of transfer or
exchange of the Notes, except for any tax or other governmental charge that may
be imposed in connection therewith.
 
MATURITY, INTEREST AND PRINCIPAL
 
    The Notes are general unsecured senior obligations of the Company, limited
to US$125,000,000 aggregate principal amount, and will mature on June 6, 2005.
See "--Ranking of the Notes."
 
    Interest on the Notes will be payable, in cash at a rate of 13 1/2% per
annum, semi-annually in arrears on each June 6 and December 6 (each, an
"Interest Payment Date"), commencing December 6, 1997, to the holders of record
of Notes at the close of business on the May 15 and November 15 immediately
preceding such Interest Payment Date. Interest will accrue from the most recent
Interest Payment Date to which interest has been paid or duly provided for or,
if no interest has been paid or duly provided for, from the Issue Date. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.
Interest on overdue principal and, to the extent permitted by law, on overdue
installments of interest will accrue at the rate of interest borne by the Notes.
 
                                       64
<PAGE>
    Whenever in the Indenture or in this "Description of the Notes" there is
mentioned, in any context, the payment of amounts based upon the payment of
principal, premium, if any, interest or of any other amount payable under or
with respect to any Note, such mention shall be deemed to include mention of the
payment of Additional Amounts to the extent that, in such context, Additional
Amounts are, were or would be payable in respect thereof.
 
ADDITIONAL AMOUNTS
 
    All payments made by the Company or any Guarantor under or with respect to
the Notes or any Guarantee will be made free and clear of and without
withholding or deduction for or on account of any present or future taxes,
duties, assessments or governmental charges of whatever nature ("Taxes") imposed
or levied by or on behalf of any taxing authority within the Federative Republic
of Brazil or Japan, unless the Company or any Guarantor is required to withhold
or deduct any amount for or on account of Taxes by law or by the interpretation
or administration thereof. If the Company or any Guarantor is required to
withhold or deduct any amount for or on account of Taxes imposed by a taxing
authority within the Federative Republic of Brazil or Japan from any payment
made under or with respect to the Notes, the Company or such Guarantor will pay
such additional amounts ("Additional Amounts") as may be necessary so that the
net amount received by each holder of Notes (including Additional Amounts) after
such withholding or deduction will not be less than the amount the holder would
have received if such Taxes had not been withheld or deducted. No such
Additional Amounts will be payable with respect to a payment made to a holder of
Notes (an "Excluded Holder") with respect to any Tax which would not have been
imposed, payable or due: (i) but for the fact that the holder (or where the
holder is an estate, nominee, trust or partnership, any fiduciary, settlor,
beneficiary or member) is a domiciliary, national or resident of, or engaging in
business, maintaining a permanent establishment or is physically present in, the
Federative Republic of Brazil or Japan; (ii) but for the failure to comply with
a request by the Company or any Guarantor to satisfy any certification,
identification or other reporting requirements, whether imposed by statute,
treaty, regulation or administrative practices, concerning nationality,
residence or connection with the Federative Republic of Brazil or Japan; or
(iii) if, where presentation is required, the presentation for payment had
occurred within 30 days after the date such payment was due and payable or was
provided for, whichever is later. The obligation to pay Taxes and Additional
Amounts in respect of Taxes shall not apply to (a) any estate, inheritance,
gift, sales, transfer, personal property or any similar Tax or (b) any Tax which
is payable otherwise than by deduction or withholding from payments made under
or with respect to the Notes. The Company or the Guarantor, as applicable, will
(i) make such withholding or deduction and (ii) remit the full amount deducted
or withheld to the relevant authority (the "Taxing Authority") in accordance
with applicable law. The Company or the Guarantor, as applicable, will obtain
certified copies of tax receipts evidencing the payment of any Taxes so deducted
or withheld from each Taxing Authority imposing such Taxes and will provide such
certified copy to the Principal Paying Agent for prompt forwarding to the
holder. The Company or the Guarantor, as applicable, will attach to each
certified copy a certificate stating (x) that the amount of withholding tax
evidenced by the certified copy was paid in connection with payments in respect
of the principal amount of Notes then outstanding and (y) the amount of such
withholding tax paid per US$1,000 of principal amount of the Notes. The
Indenture will further provide that, if the Company or any Guarantor conducts
business in any jurisdiction (the "Taxing Jurisdiction") other than the
Federative Republic of Brazil or Japan in a manner which causes Holders to be
liable for taxes on payments under the Notes or any Guarantee, as the case may
be, for which they would not have been so liable but for such conduct of
business in the Taxing Jurisdiction, the Additional Amounts provision described
above shall be considered to apply to such Holders as if references in such
provision to "Taxes" included taxes imposed by way of deduction or withholding
by such Taxing Jurisdiction. See "Tax Considerations--United States--Tax
Considerations Applicable to Holding Notes--Effect of Brazilian Withholding
Taxes."
 
    At least 30 days prior to each date on which any payment under or with
respect to the Notes is due and payable (unless such obligation to pay
Additional Amounts arises after the 30th day prior to such date,
 
                                       65
<PAGE>
in which case it shall be promptly thereafter), if the Company or any Guarantor
will be obligated to pay Additional Amounts with respect to such payment, the
Company or such Guarantor will deliver to the Trustee and each Paying Agent an
Officers' Certificate stating the fact that such Additional Amounts will be
payable and the amounts so payable and will set forth such other information
necessary to enable the Trustee and each Paying Agent to pay such Additional
Amounts to holders of Notes on the payment date. Each Officers' Certificate
shall be relied upon until receipt of a further Officers' Certificate addressing
such matters.
 
ESCROW ACCOUNT
 
    The Indenture provided that upon the closing of the offering of the Old
Notes, the Company purchase and pledge to the Trustee for the benefit of holders
of the Notes the Pledged Securities in such amount as will be sufficient upon
receipt of scheduled interest and principal payments of such securities, based
on the report of an internationally recognized firm of independent public
accountants selected by the Company, to provide for payment in full of the first
six scheduled interest payments due on the Notes through June 6, 2000.
Accordingly, the Company used approximately US$46 million of the net proceeds of
the sale of the Old Notes to acquire the Pledged Securities. The Pledged
Securities are pledged by the Company to the Trustee for the benefit of the
holders of Notes pursuant to the Pledge Agreement and are held in the United
States by the Trustee in the Pledge Account (as defined herein). A failure by
the Company to pay interest on the Notes in a timely manner through June 6, 2000
will constitute an immediate Event of Default under the Indenture, with no grace
or cure period. The Pledge Account does not include collateral to secure any
Additional Amounts which might become payable with respect to the Notes. See "--
Additional Amounts."
 
    Pursuant to the Pledge Agreement, interest earned on the Pledged Securities
will be added to the Pledge Account. In the event that the funds or Pledged
Securities held in the Pledge Account exceed the amount sufficient, based on the
report of an internationally recognized firm of independent public accountants
selected by the Company, to provide for payment in full of the first six
scheduled interest payments due on the Notes (or, in the event an interest
payment or payments have been made, an amount sufficient to provide for payments
in full or any interest payments remaining, up to and including the sixth
scheduled interest payment) the Trustee will be permitted to release to the
Company at the Company's request any such excess amount. The Notes will be
secured by a security interest in the Pledged Securities and in the Pledge
Account and, accordingly, the Pledged Securities and the Pledge Account will
also secure repayment of the principal amount of the Notes to the extent of such
security.
 
    Pursuant to the Pledge Agreement, if the Company makes the first six
scheduled interest payments on the Notes in a timely manner, immediately after
the sixth scheduled interest payment any remaining Pledged Securities will be
released from the Pledge Account and thereafter the Notes will be unsecured.
 
REDEMPTION
 
    OPTIONAL REDEMPTION
 
    Except as set forth below, the Notes will not be redeemable at the Company's
option prior to maturity.
 
    OPTIONAL REDEMPTION BY THE COMPANY.  The Notes will be redeemable, in whole
or in part, at any time on or after June 6, 2001 at the option of the Company,
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
 
                                       66

</TABLE>
 
    Notwithstanding the foregoing, on or prior to June 6, 2000, the Company may,
at its option, use the net proceeds of one or more Significant Equity Offerings
(as defined below) yielding gross cash proceeds of not less than US$35,000,000
(or, to the extent non-U.S. dollar denominated, the U.S. Dollar Equivalent
thereof) to redeem up to an aggregate of 35% of the principal amount of the
Notes originally issued from the holders of Notes on a PRO RATA basis (or as
nearly PRO RATA as practicable), at a redemption price of 113 1/2% of the
principal amount thereof, plus accrued and unpaid interest to the redemption
date; PROVIDED that not less than US$81,250,000 aggregate principal amount of
Notes would remain outstanding immediately after such redemption. To effect the
foregoing redemption, the Company must mail a notice of redemption not later
than 60 days after the consummation of the Significant Equity Offering that
resulted in the requisite gross proceeds.
 
    As used above, "Significant Equity Offering" means a public offering of
Capital Stock (other than Disqualified Capital Stock) of the Company (or
American Depositary Receipts or Global Depositary Receipts representing such
Capital Stock) either (x) in the United States pursuant to an offering
registered under the Securities Act or (y) in Brazil pursuant to an offering
registered with the Comissao de Valores Mobiliarios ("CVM") and listed on the
Sao Paulo Stock Exchange or Rio de Janeiro Stock Exchange and/ or (z) in the
United Kingdom pursuant to an offering that results in such Capital Stock (or
Global Depositary Receipts representing such Capital Stock) being listed on the
London Stock Exchange or the Luxembourg Stock Exchange.
 
    REDEMPTION FOR CHANGES IN WITHHOLDING TAXES.  The Notes may be redeemed at
the option of the Company, in whole but not in part, at any time prior to
maturity if (A) there is any change in or amendment to the Treaty to Avoid
Double Taxation entered into between the Federative Republic of Brazil and
Japan, approved by Legislative Decree No. 43 dated November 23, 1967, and
enacted in Brazil by Decree No. 61,899 dated December 14, 1967, as amended by
Decree No. 81,194 dated January 9, 1978, which has the effect of increasing the
rate of tax applicable under such treaty to a rate exceeding 15.0% of interest
payable; or (B) (i) as the result of any change in or amendment to the laws or
regulations of the Federative Republic of Brazil or Japan, the Company has or
will become obligated to pay, or (ii) any act is taken by a taxing authority of
the Federative Republic of Brazil or Japan after the date of issuance of the
Notes (whether or not such act is taken with respect to the Company or any
Affiliate thereof) that results in a substantial probability that the Company
will be required to pay, Additional Amounts (excluding interest and penalties)
in excess of the Additional Amounts that the Company would be obligated to pay
if Brazilian Taxes (excluding interest and penalties) were payable with respect
to such payments of interest at a rate of 15.0% and such obligation cannot be
avoided by the Company, taking reasonable measures available to it, upon not
more than 60 nor less than 30 days' notice to the holders of such Notes (with
copies to the Trustee and each Paying Agent) at a redemption price of 100% of
the principal amount thereof, plus accrued and unpaid interest to the redemption
date, plus any such Additional Amounts payable with respect to such redemption
price and interest as provided under "--Additional Amounts." Prior to the giving
of notice of redemption of the Notes as described herein and as a condition to
any such redemption, the Company will deliver to the Trustee an Officers'
Certificate (together with a copy of the written opinion of counsel to the
effect that the applicable rate has so increased, or the Company has or will
become so obligated, or that an act taken by a taxing authority of Brazil has
resulted in a substantial probability that the Company will become so obligated
to pay Additional Amounts as a result of such
 
                                       67
<PAGE>
change, amendment, interpretation or act), stating that the Company is entitled
to effect such redemption and setting forth in reasonable detail a statement of
facts relating thereto. No notice of redemption shall be given earlier than 60
days prior to the earliest date on which the Company would be obligated or there
is a substantial probability that the Company would be obligated to pay such
Additional Amounts were a payment in respect of the Notes then due and, at the
time such notice of redemption is given, such obligation to pay, or such
substantial probability that the Company will be required to pay, such
Additional Amounts remains in effect.
 
    SELECTION; EFFECT OF REDEMPTION NOTICE.  Notice of an optional redemption
must be given no less than 30 nor more than 60 days prior to the applicable
redemption date. In the case of a partial redemption, selection of the Notes for
redemption will be made by lot, PRO RATA or by such other method as the Trustee
in its sole discretion deems fair and appropriate or in such manner as complies
with the requirements of the principal securities exchange, if any, on which the
Notes being redeemed are listed and DTC; PROVIDED that any redemption following
one or more Significant Equity Offerings will be made on a PRO RATA or on as
nearly a PRO RATA basis as practicable (subject to the procedures of DTC). Upon
giving of a redemption notice, interest on Notes called for redemption will
cease to accrue from and after the date fixed for redemption (unless the Company
defaults in providing the funds for such redemption) and, upon redemption on
such redemption date, such Notes will cease to be outstanding.
 
    MANDATORY REDEMPTION
 
    SINKING FUND.  The Company will not be required to make any mandatory
sinking fund payments in respect of the Notes.
 
    OFFERS TO PURCHASE UPON CHANGE OF CONTROL AND CERTAIN ASSET
SALES.  Following the occurrence of a Change of Control, the Company will be
required to make an offer to purchase all outstanding Notes at a price of 101%
of the principal amount thereof, plus accrued and unpaid interest, if any, to
the date of purchase, and purchase all Notes validly tendered pursuant thereto.
In addition, the Company may be obligated to make an offer to purchase Notes
with a portion of the Net Cash Proceeds of certain Asset Sales at a price of
100% of the principal amount thereof, plus accrued and unpaid interest, if any,
to the date of purchase. See "--Certain Covenants--Change of Control" and
"--Disposition of Proceeds of Asset Sales," respectively.
 
                                       68
<PAGE>
BRAZILIAN CENTRAL BANK CONSENT FOR OPTIONAL AND MANDATORY REDEMPTION OF NOTES
 
    The consent of the Brazilian Central Bank is needed for the payment of
principal of, premium on and interest on the Notes upon acceleration of the
Notes following an Event of Default. In addition, the consent of the Brazilian
Central Bank is needed for payments in respect of the Notes upon (i) a
redemption or repurchase by the Company at its option, (ii) a Change of Control
or (iii) an Asset Sale. See "Risk Factors--Risk Factors Relating to
Brazil--Controls and Restrictions on U.S. Dollar Remittances."
 
RANKING
 
    The indebtedness of the Company and the Guarantors evidenced by the Notes
and the Guarantees will rank senior in right of payment to all indebtedness of
the Company or such Guarantors, as the case may be, that is subordinated to the
Notes or such Guarantees, as applicable, by its terms and will rank PARI PASSU
in right of payment with all other existing or future unsecured and
unsubordinated indebtedness of the Company or such Guarantors, as the case may
be. At the Issue Date, it is expected that there will be no outstanding
indebtedness of the Company ranking PARI PASSU with or junior in right of
payment to the Notes. As of the date of this Prospectus, the Company has no
Subsidiaries and, accordingly, there are no Guarantors. The Notes will be
effectively subordinated in right of payment to all liabilities, including trade
payables, of any Subsidiaries organized or acquired by the Company hereafter,
except to the extent such Subsidiaries are required to become Guarantors as set
forth under "--Certain Covenants--Issuance of Guarantees by Material Restricted
Subsidiaries; Release of Guarantees." See "Use of Proceeds" and
"Capitalization."
 
CERTAIN COVENANTS
 
    Set forth below are certain covenants that are contained in the Indenture.
 
    LIMITATION ON ADDITIONAL INDEBTEDNESS AND PREFERRED STOCK OF RESTRICTED
SUBSIDIARIES. The Indenture provides that (i) the Company will not, and will not
permit any Restricted Subsidiary to, directly or indirectly, create, incur,
assume, issue, guarantee or in any manner become directly or indirectly liable
for or with respect to, contingently or otherwise, the payment of (collectively,
to "incur") any Indebtedness (including any Acquired Indebtedness) and (ii) the
Company will not permit any Restricted Subsidiary that is not a Guarantor to
issue any Preferred Stock, in each case, except for Permitted Indebtedness;
PROVIDED that (a) the Company and any Guarantor will be permitted to incur
Indebtedness (including Acquired Indebtedness) and (b) any Restricted Subsidiary
that is not a Guarantor will be permitted to issue Preferred Stock, if, in each
case, after giving PRO FORMA effect to such incurrence or issuance and any
concurrent financing (including the application of the net proceeds therefrom),
the ratio of (x) Total Consolidated Indebtedness and Subsidiary Preferred Stock
to (y) Annualized Pro Forma Consolidated Operating Cash Flow for the latest
fiscal quarter for which consolidated financial statements of the Company are
available preceding the date of such incurrence or issuance would be either (1)
less than or equal to 5.75 to 1.00 if such incurrence or issuance is on or prior
to December 31, 2000 or (2) less than or equal to 5.00 to 1.00 if such
incurrence or issuance is on or after January 1, 2001.
 
    LIMITATION ON RESTRICTED PAYMENTS.  The Indenture provides that the Company
will not, and will not permit any of the Restricted Subsidiaries to, make,
directly or indirectly, any Restricted Payment unless:
 
        (i) no Default shall have occurred and be continuing at the time of or
    after giving effect to such Restricted Payment;
 
        (ii) immediately after giving effect to such Restricted Payment, the
    Company would be able to incur US$1.00 of Indebtedness under the proviso of
    the covenant described under "Limitation on Additional Indebtedness and
    Preferred Stock of Restricted Subsidiaries"; and
 
                                       69
<PAGE>
       (iii) immediately after giving effect to such Restricted Payment, the
    aggregate amount of all Restricted Payments declared or made on or after the
    Issue Date (including any Designation Amount) does not exceed an amount
    equal to the sum of (a) the difference between (x) the Cumulative Adjusted
    Available Cash Flow determined at the time of such Restricted Payment and
    (y) 150% of the cumulative Consolidated Interest Expense of the Company
    determined for the period commencing on the Issue Date and ending on the
    last day of the latest fiscal quarter for which consolidated financial
    statements of the Company are available preceding the date of such
    Restricted Payment PLUS (b) the aggregate net cash proceeds received by the
    Company (x) as capital contributions to the Company after the Issue Date or
    (y) from the issue or sale (other than to a Restricted Subsidiary) of its
    Capital Stock (other than Disqualified Stock) on or after the Issue Date
    (including, without duplication, upon the exercise of options, warrants or
    rights) PLUS (c) the aggregate net proceeds received by the Company from the
    issuance (other than to a Restricted Subsidiary) on or after the Issue Date
    of its Capital Stock (other than Disqualified Stock) upon the conversion of,
    or exchange for, Indebtedness of the Company or a Restricted Subsidiary PLUS
    (d) in the case of the disposition or repayment of any Investment
    constituting a Restricted Payment (other than an Investment made pursuant to
    clause (v) of the following paragraph) made after the Issue Date an amount
    equal to the lesser of the return of capital with respect to such Investment
    and the cost of such Investment, in either case, less the cost of the
    disposition of such Investment PLUS (e) in the case of the Revocation of the
    Designation of a Subsidiary as an Unrestricted Subsidiary, an amount equal
    to the consolidated net Investment (exclusive of the net amount of any
    Investment made in such Subsidiary while it was an Unrestricted Subsidiary)
    in such Subsidiary on the date of Revocation but not in an amount exceeding
    the sum of (1) the Designation Amount with respect to such Subsidiary and
    (2) the net amount of any Investment made in such Subsidiary while it was an
    Unrestricted Subsidiary, MINUS (f) 50% of the aggregate outstanding
    principal amount of Indebtedness incurred pursuant to clause (e) of the
    definition of "Permitted Indebtedness." For purposes of the preceding
    clauses (b)(y) and (c) and without duplication, the value of the aggregate
    net cash proceeds received by the Company upon the issuance of Capital Stock
    either upon the conversion of convertible Indebtedness or in exchange for
    outstanding Indebtedness or upon the exercise of options, warrants or rights
    will be the net cash proceeds received upon the issuance of such
    Indebtedness, options, warrants or rights plus the incremental amount
    received by the Company upon the conversion, exchange or exercise thereof.
 
    For purposes of determining the amount expended for Restricted Payments,
cash distributed shall be valued at the face amount thereof and property other
than cash shall be valued at its Fair Market Value.
 
    The provisions of this covenant shall not prohibit (i) the payment of any
dividend or other distribution within 60 days after the date of declaration
thereof, if at such date of declaration such payment would comply with the
provisions of the Indenture; (ii) so long as no Default shall have occurred and
be continuing, the purchase, redemption, retirement or other acquisition of any
shares of Capital Stock of the Company (A) in exchange for or conversion into or
(B) out of the net cash proceeds of the substantially concurrent issue and sale
(other than to a Restricted Subsidiary) of shares of Capital Stock of the
Company (other than Disqualified Stock); PROVIDED that any such net cash
proceeds pursuant to the immediately preceding clause (B) are excluded from
clause (iii)(b) of the preceding paragraph; (iii) so long as no Default shall
have occurred and be continuing, the purchase, redemption, retirement,
defeasance or other acquisition of (A) Preferred Stock of any Restricted
Subsidiary that is not a Guarantor made by exchange for or conversion into, or
out of the net cash proceeds of, a substantially concurrent issue and sale
(other than to a Restricted Subsidiary) of (x) Capital Stock (other than
Disqualified Stock) of the Company or (y) other Preferred Stock of such
Restricted Subsidiary having an Average Life to Stated Maturity equal to or
greater than the Average Life to Stated Maturity of the Preferred Stock being
purchased, redeemed, retired, defeased or otherwise acquired or (B) Subordinated
Indebtedness made by exchange for or conversion into, or out of the net cash
proceeds of, a substantially concurrent issue and sale (other than to a
Restricted Subsidiary) of (x) Capital Stock (other than Disqualified Stock) of
the Company or (y) other Subordinated Indebtedness having an Average Life to
Stated Maturity equal to or
 
                                       70
<PAGE>
greater than the Average Life to Stated Maturity of the Subordinated
Indebtedness being purchased, redeemed, retired, defeased or otherwise acquired
PROVIDED that any such net cash proceeds pursuant to the immediately preceding
clause (iii)(A) or (iii)(B) are excluded from clause (iii)(b) of the preceding
paragraph; (iv) from and after the date that any Shareholder Commitments shall
cease to be effective under applicable law, so long as no Default shall have

exceeding the amount mandated by applicable law; (v) so long as no Default shall
have occurred and be continuing, any Investment constituting a Restricted
Payment by the Company or any Restricted Subsidiary in any person (including any
Unrestricted Subsidiary) in an amount not to exceed US$10,000,000 (or, to the
extent non-U.S. dollar denominated, the U.S. Dollar Equivalent thereof) in the
aggregate at any time outstanding; (vi) so long as no Default shall have
occurred and be continuing and prior to a Liquidation Event (as defined in the
LLC Agreement) with respect to Holding LLC, dividends to Holding LLC in an

Taxes attributable solely to their interest in Holding LLC; (vii) the
redemption, repurchase, retirement or other acquisition of any Capital Stock of
the Company from an employee or former employee of the Company or any of its
Subsidiaries in connection with such employee's death, disability or termination
of employment; PROVIDED that the amount expended by the Company or any of its
Restricted Subsidiaries in connection with such redemption, repurchase,
retirement or other acquisition does not exceed US$500,000 (or, to the extent
non-U.S. dollar denominated, the U.S. Dollar Equivalent thereof) per year;
PROVIDED, FURTHER, that any portion of such permitted amount which is not
expended in one year may be carried forward for up to two consecutive years; or
(viii) so long as no Default shall have occurred and be continuing, the making
of a direct or indirect Investment constituting a Restricted Payment out of the
proceeds of a concurrent capital contribution in respect of existing Capital
Stock (other than Disqualified Capital Stock) of the Company or from the issue
or sale (other than to a Subsidiary) of Capital Stock (other than Disqualified
Capital Stock) of the Company; PROVIDED that any such net cash proceeds are
excluded from clause (iii)(b) of the second preceding paragraph. Restricted
Payments of the type set forth in the preceding clauses (iv), (v), (vi) and
(vii) shall be included in making the determination of available amounts under
clause (iii) of the preceding paragraph.
 
    The Indenture provides that the Company will be required to obtain, as a
condition to the issuance of the Notes, and to thereafter maintain, enforceable
written commitments (the "Shareholder Commitments") from each shareholder of the
Company agreeing that such shareholder will not exercise its voting rights to
receive mandatory statutory dividends (without limiting such shareholder's right
otherwise to receive dividends pursuant to and in compliance with the covenant
described under "Limitation on Restricted Payments"), provided that a
Shareholder Commitment will cease to be effective on the first to occur of (w)
the date that shares of Capital Stock of the Company are issued and listed on a
Brazilian securities exchange in connection with a bona fide public offering of
such shares or the date that any shares of the Capital Stock of the Company are
otherwise effectively listed and traded on any Brazilian securities exchange;
(x) the date that none of the Notes remain outstanding; (y) June 6, 2002; or (z)
the date that such commitment is no longer effective, enforceable or legal under
applicable Brazilian laws and regulations (including without limitation any
construction or interpretation thereof by the CVM, any court or any other
governmental authority). The Indenture will provide that the Company will obtain
Shareholder Commitments in connection with any future issuances of Capital Stock
to the extent the Shareholder Commitment would then be effective, enforceable
and legal under the terms of the foregoing proviso.
 
    LIMITATION ON LIENS SECURING CERTAIN INDEBTEDNESS.  The Indenture provides
that the Company will not, and will not permit any Restricted Subsidiary to,
create, incur, assume or suffer to exist any Liens of any kind against or upon
any of its property or assets, or any proceeds therefrom, which secure either
(i) Subordinated Debt Securities unless the Notes and the Guarantees, as
applicable, are secured by a Lien
 
                                       71
<PAGE>
on such property, assets or proceeds that is senior in priority to the Liens
securing such Subordinated Debt Securities or (ii) Pari Passu Debt Securities
unless the Notes and the Guarantees, as applicable, are equally and ratably
secured with the Liens securing such Pari Passu Debt Securities. The Indenture
will also provide that the Company will not create, incur or suffer to exist any
Lien of any kind (other than the Lien of the Pledgee) against or upon the
Pledged Securities and will not terminate the Lien of the Pledgee on the Pledged
Securities.
 
    ISSUANCE OF GUARANTEES BY MATERIAL RESTRICTED SUBSIDIARIES; RELEASE OF
GUARANTEES.  The Indenture provides that each Material Restricted Subsidiary
will become a guarantor of the Notes (each a "Guarantor" and collectively the
"Guarantors"). Each Guarantor will fully and unconditionally guarantee
(collectively, the "Guarantees"), jointly and severally, on a senior unsecured
basis to each holder of a Note the due and punctual payment of the principal of,
premium, if any, and interest on, and all other amounts owing in respect of such
Note (and any Additional Amounts payable in respect thereof) and under the
Indenture. Each Guarantor will deliver a written instrument in the form attached
to the Indenture evidencing its Guarantee.
 
    Pursuant to each Guarantee, if the Company defaults in payment of any amount
owing in respect of any Notes, the Guarantor will be obligated to duly and
punctually pay the same. Pursuant to the terms of the Indenture, each of the
Guarantors has agreed that its obligations under its Guarantee will be
unconditional, irrespective of the validity, regularity or enforceability of the
Notes or the Indenture, the absence of any action to enforce the same or any
other circumstance which might otherwise constitute a legal or equitable
discharge or defense of a guarantor.
 
    If no Default exists or would exist under the Indenture, concurrently with
any sale or disposition (by merger or otherwise) of any Guarantor (other than a
transaction subject to the provisions described under "--Consolidation, Merger,
Sale of Assets, Etc.") by the Company or a Restricted Subsidiary to any person
that is not an Affiliate of the Company or any of the Restricted Subsidiaries
which is in compliance with the terms of the Indenture, such Guarantor will
automatically and unconditionally be released from all obligations under its
Guarantee.
 
    BUSINESS OF THE COMPANY AND RESTRICTED SUBSIDIARIES.  The Indenture will
provide that the Company will not, and will not permit any of the Restricted
Subsidiaries to, be principally engaged in any business or activity other than a
Permitted Business.
 
    LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED
SUBSIDIARIES.  The Indenture provides that the Company will not, and will not
permit any Restricted Subsidiary to, directly or indirectly, create or otherwise
enter into or cause to become effective any consensual encumbrance or consensual
restriction of any kind on the ability of any Restricted Subsidiary to (a) pay
dividends, in cash or otherwise, or make any other distributions on its Capital
Stock or any other interest or participation in, or measured by, its profits
owned by the Company or any Restricted Subsidiary, (b) pay any Indebtedness owed
to the Company or a Restricted Subsidiary, (c) make any Investment in the
Company or any Restricted Subsidiary or (d) transfer any of its property or
assets to the Company or to any Restricted Subsidiary, except for (i) any such
customary encumbrance or restriction contained in a security document creating a
Lien permitted under the Indenture to the extent such encumbrance or restriction
applies to action following a default in respect of the applicable secured
obligation, (ii) any such encumbrance or restriction pursuant to any agreement
existing on the Issue Date, (iii) any such encumbrance or restriction with
respect to a Restricted Subsidiary that is not a Restricted Subsidiary on the
Issue Date which encumbrance or restriction is in existence at the time such
person becomes a Restricted Subsidiary but not created in contemplation thereof,
(iv) any such encumbrance or restriction existing under any agreement that
refinances, replaces or amends an agreement containing a restriction permitted
by clause (iii) above, PROVIDED that the terms and conditions of any such
restrictions are not materially less favorable to the holders of Notes than
those under or pursuant to the agreement being replaced or amended or the
 
                                       72
<PAGE>
agreement evidencing the indebtedness refinanced, (v) any such encumbrance or
restriction imposed pursuant to an agreement which has been entered into for the
sale or disposition of all or substantially all of the Capital Stock or assets
of such Restricted Subsidiary and (vi) customary non-assignment provisions in
leases entered into in the ordinary course of business and consistent with past
practices.
 
    LIMITATION ON TRANSACTIONS WITH AFFILIATES.  The Indenture provides that the
Company will not, and will not permit, cause, or suffer any Restricted
Subsidiary to, conduct any business or enter into any transaction or series of
related transactions with or for the benefit of any of their respective
Affiliates or any beneficial holder of ten percent or more of any class of
Capital Stock of the Company or any officer or director of the Company or any
Restricted Subsidiary (each an "Affiliate Transaction"), except on terms that
are fair and reasonable to the Company or such Restricted Subsidiary, as the
case may be. Each Affiliate Transaction involving aggregate payments or other
property having a Fair Market Value in excess of US$2,000,000 (or, to the extent
non-U.S. dollar denominated, the U.S. Dollar Equivalent of such amount) shall be
approved by the Board of Directors of the Company, such approval to be evidenced
by a Resolution of the Board of Directors (delivered to the Trustee) stating
that the Board of Directors of the Company (including a majority of the
Disinterested Directors) has determined that such transaction complies with the
foregoing provisions. In addition to the foregoing, with respect to any
Affiliate Transaction involving aggregate consideration in excess of
US$5,000,000 (or, to the extent non-U.S. dollar denominated, the U.S. Dollar
Equivalent of such amount) or more, the Company must obtain a written opinion
(delivered to the Trustee) from an Independent Financial Advisor stating that
the terms of such Affiliate Transaction to the Company or the Restricted
Subsidiary, as the case may be, are fair from a financial point of view.
 
    Notwithstanding the foregoing, the restrictions set forth in this covenant
shall not apply to (i) transactions with or among the Company and/or any of the
Restricted Subsidiaries; PROVIDED in any such case, no officer, director or
beneficial holder of 10% or more of any class of Capital Stock of the Company
shall beneficially own any Capital Stock of any such Restricted Subsidiary, (ii)
transactions between the Company and any Restricted Subsidiary that are solely
for the benefit of the Company or a Guarantor, (iii) transactions between or
among Unrestricted Subsidiaries, (iv) any dividend permitted by the covenant
"Limitation on Restricted Payments," (v) directors' fees, indemnification and
similar arrangements, officers' indemnification, employee stock option or
employee benefit plans, employee salaries and bonuses or legal fees paid or
created in the ordinary course of business, (vi) payments made to a License
Vehicle in reimbursement of expenses to the extent increased to maintain the
effectiveness of any paging licenses used by the Company or any Restricted
Subsidiary and (vii) payments pursuant to each of the following arrangements as
in effect on June 6, 1997: (A) the Technical Services Agreement, (B) the
Subscription Agreement, (C) the Paging License Operating Agreements and (D) the
Paging License Transfer Agreements.
 
    CHANGE OF CONTROL.  Following the occurrence of a Change of Control (the
date of such occurrence being the "Change of Control Date"), the Company shall
notify the holders of the Notes, in the manner prescribed by the Indenture, of
such occurrence and shall make an offer to purchase (the "Change of Control
Offer"), on a business day (the "Change of Control Payment Date") not later than
60 days following the Change of Control Date, all Notes then outstanding at a
purchase price equal to 101% of the principal amount thereof plus accrued and
unpaid interest, if any, to any Change of Control Payment Date. Notice of a
Change of Control Offer shall be given to holders of Notes, not less than 25
days nor more than 45 days before the Change of Control Payment Date. The Change
of Control Offer is required to remain open for at least 20 business days and
until the close of business on the Change of Control Payment Date. The Company's
obligations may be satisfied if a third party makes the Change of Control Offer
in the manner, at the times and otherwise in compliance with the requirements
applicable to a Change of Control Offer made by the Company and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.
 
                                       73
<PAGE>
    If a Change of Control Offer is made, there can be no assurance that the
Company or the Guarantors will have available funds sufficient to pay for all of
the Notes that might be delivered by holders of Notes seeking to accept the
Change of Control Offer.
 
    If the Company makes a Change of Control Offer, the Company will comply with
all applicable tender offer laws and regulations, including, to the extent
applicable, Section 14(e) and Rule 14e-1 under the Exchange Act, and any other
applicable United States or foreign securities laws and regulations and any
applicable requirements of any securities exchange on which the Notes are
listed.
 
    DISPOSITION OF PROCEEDS OF ASSET SALES.  The Indenture provides that the
Company will not, and will not permit any Restricted Subsidiary to, make any
Asset Sale, unless (a) the Company or such Restricted Subsidiary, as the case
may be, receives consideration at the time of such Asset Sale at least equal to
the Fair Market Value of the shares or assets sold or otherwise disposed of and
(b) at least 75% of such consideration consists of cash or Cash Equivalents
(provided that the following shall be deemed cash for purposes of this provision
and be treated as Net Cash Proceeds, subject to application as hereinafter
provided: the amount of (x) any liabilities (as shown on the balance sheet or in
the notes thereto of the Company or such Restricted Subsidiary) of the Company
or such Restricted Subsidiary that are assumed (and from which the Company or
such Restricted Subsidiary is unconditionally released) in connection with such
Asset Sale by the transferee or purchaser of such assets or on behalf of such
transferee or purchaser by a third party and (y) any notes or other assets
received by the Company or such Restricted Subsidiary from such transferee or
purchaser that are immediately sold or transferred (on a non-recourse basis) for
cash or Cash Equivalents). To the extent the Net Cash Proceeds of any Asset Sale
are not required to be applied to repay, and permanently reduce the commitments
under, any Specified Indebtedness or are required but are not so applied, the
Company or such Restricted Subsidiary, as the case may be, may apply such Net
Cash Proceeds within 365 days thereof, to an investment in properties and assets
that will be used in a Permitted Business (or in Capital Stock of any person
that will become a Restricted Subsidiary as a result of such investment if such
person principally owns properties and assets that will be used in a Permitted
Business) of the Company or any Restricted Subsidiary ("Replacement Assets").
Pending the final application of any such Net Cash Proceeds in accordance with
the second sentence of this paragraph or to an Asset Sale Offer, the Company or
such Restricted Subsidiary may invest such Net Cash Proceeds in any manner not
prohibited by the Indenture and may temporarily repay Specified Indebtedness.
The Pro Rata Share of Net Cash Proceeds from any Asset Sale that are neither
used to repay, and permanently reduce the commitments under, any Specified
Indebtedness nor invested in Replacement Assets within such 365-day period shall
constitute "Excess Proceeds" subject to disposition as provided below.
 
    Within 30 days after the aggregate amount of Excess Proceeds equals or
exceeds US$10,000,000 (or, to the extent non-U.S. dollar denominated, the U.S.
Dollar Equivalent of such amount), the Company shall make an offer to purchase
(an "Asset Sale Offer"), from all holders of the Notes, Notes having an
aggregate purchase price equal to such Excess Proceeds at a price in cash equal
to 100% of the outstanding principal amount thereof plus accrued and unpaid
interest, if any, to the purchase date. Each Asset Sale Offer shall remain open
for a period of 20 business days or such longer period as may be required by
law. To the extent that the aggregate purchase price for Notes tendered pursuant
to an Asset Sale Offer is less than the Excess Proceeds available for such
offer, the Company and the Restricted Subsidiaries may use such deficiency for
general corporate purposes. If the aggregate purchase price for the Notes
validly tendered and not withdrawn by holders thereof exceeds the Excess
Proceeds available for such offer, Notes to be purchased will be selected on a
PRO RATA basis or as nearly PRO RATA as practicable. Upon completion of such
Asset Sale Offer, the amount of Excess Proceeds shall be reset to zero.
 
    If the Company is required to make an Asset Sale Offer, the Company will
comply with all applicable tender offer laws and regulations, including, to the
extent applicable, Section 14(e) and Rule 14e-1 under
 
                                       74
<PAGE>
the Exchange Act, and any other applicable United States or foreign securities
laws and regulations and any applicable requirements of any securities exchange
on which the Notes are listed.
 
    REPORTS.  The Indenture provides that, whether or not the Company has a
class of securities registered under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), following the Exchange Offer or the effectiveness
of any Notes Shelf Registration Statement, the Company shall furnish without
cost to each holder of Notes and file with the Commission (whether or not the
Company is a public reporting company at the time), the Trustee and the Initial
Purchasers: (i) within 120 days after the end of each fiscal year of the
Company, annual reports on Form 20-F (or any successor form) containing the
information required to be contained therein (or required in such successor
form); (ii) within 60 days after the end of each of the first three fiscal
quarters of each fiscal year, reports on Form 6-K (or any successor form)
containing substantially the same information required to be contained in Form
10-Q (or required in any successor form); and (iii) promptly from time to time
after the occurrence of an event required to be therein reported, such other
reports on Form 6-K (or any successor form) containing substantially the same
information required to be contained in Form 8-K (or required in any successor
form). Prior to the effectiveness of the Exchange Offer Registration Statement
or the filing of any Notes Shelf Registration Statement with the Commission, the
Company will file with the Trustee and provide the Initial Purchasers, all of
the information that would have been required to have been filed with the
Commission pursuant to clauses (i), (ii) and (iii) above. Each of the reports
will be prepared in accordance with U.S. GAAP consistently applied and will be
prepared in accordance with the applicable rules and regulations of the
Commission.
 
    The Indenture also provides that, for so long as any Transfer Restricted
Notes remain outstanding, the Company will furnish to the holders of the Notes
and to securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act.
 
    LIMITATION ON DESIGNATIONS OF UNRESTRICTED SUBSIDIARIES.  The Indenture
provides that the Company may designate any Subsidiary of the Company as an
"Unrestricted Subsidiary" under the Indenture (a "Designation") only if:
 
        (a) no Default shall have occurred and be continuing at the time of or
    after giving effect to such Designation; and
 
        (b) the Company would be permitted under the Indenture to make an
    Investment under all applicable provisions of the covenant "Limitation on
    Restricted Payments" at the time of Designation (assuming the effectiveness
    of such Designation) in an amount (the "Designation Amount") equal to the
    Fair Market Value of the Investment of the Company and the Restricted
    Subsidiaries in such Subsidiary on such date.
 
    In the event of any such Designation, (i) the Company shall be deemed to
have made an Investment constituting a Restricted Payment pursuant to the
covenant "Limitation on Restricted Payments" for all purposes of the Indenture
in the Designation Amount and (ii) upon such Designation, the Subsidiary that is
the subject of such Designation shall be deemed to be released from its
Guarantee, if any. The Indenture will further provide that the Company shall not
and shall not permit any Restricted Subsidiary to, at any time (x) guarantee any
Indebtedness of any Unrestricted Subsidiary (including any undertaking,
agreement or instrument evidencing such Indebtedness); PROVIDED that the Company
or any Restricted Subsidiary may pledge Capital Stock or Indebtedness of any
Unrestricted Subsidiary on a non-recourse basis such that the pledgee has no
claim whatsoever against the pledgor other than to obtain such pledged property
or (y) become or be directly or indirectly liable for any Indebtedness of any
Unrestricted Subsidiary or (z) be directly or indirectly liable for any
Indebtedness which provides that the holder thereof may (upon notice, lapse of
time or both) declare a default thereon or cause the payment thereof to be
accelerated or payable prior to its final scheduled maturity upon the occurrence
of a default with respect to any Indebtedness of
 
                                       75
<PAGE>
any Unrestricted Subsidiary (including any right to take enforcement action
against such Unrestricted Subsidiary), except in the case of clause (x) or (y)
to the extent permitted under the covenant "Limitation on Restricted Payments."
 
    The Indenture will further provide that the Company may revoke any
Designation of a Subsidiary as an Unrestricted Subsidiary (a "Revocation") if:
 
        (a) no Default shall have occurred and be continuing at the time of and
    after giving effect to such Revocation; and
 
        (b) all Liens and Indebtedness of such Unrestricted Subsidiary
    outstanding immediately following such Revocation would, if incurred at such
    time, have been permitted to be incurred for all purposes of the Indenture;
    and
 
        (c) such Subsidiary issues a Guarantee to the extent required under
    "--Issuance of Guarantees by Material Restricted Subsidiaries; Release of
    Guarantees."
 
    All Designations and Revocations must be evidenced by Board Resolutions of
the Company delivered to the Trustee certifying compliance with the foregoing
provisions.
 
    LIMITATION ON STATUS AS INVESTMENT COMPANY.  The Indenture will provide that
the Company will not, and will not permit any of its Subsidiaries or controlled
Affiliates to, conduct its business in a fashion that would cause the Company to
be required to register as an "investment company" (as that term is defined in
the Investment Company Act of 1940, as amended (the "Investment Company Act")),
or otherwise become subject to regulation under the Investment Company Act. For
purposes of establishing the Company's compliance with this provision, any
exemption which is or would become available under Section 3(c)(1) or Section
3(c)(7) of the Investment Company Act will be disregarded.
 
CONSOLIDATION, MERGER, SALE OF ASSETS, ETC.
 
    The Indenture provides that the Company will not, in a single transaction or
through a series of transactions, consolidate, amalgamate or combine with or
merge with or into or, directly or indirectly, sell, assign, convey, lease,
transfer or otherwise dispose of all or substantially all of its properties and
assets to any person or persons, and the Company will not permit any of the
Restricted Subsidiaries to enter into any such transaction or series of
transactions if such transaction or series of transactions, in the aggregate,
would result in the sale, assignment, conveyance, lease, transfer or disposition
of all or substantially all of the properties and assets of the Company and the
Restricted Subsidiaries, taken as a whole, to any person or persons, unless (a)
the Company shall be the continuing person or the resulting, surviving or
transferee person (in either case, the "surviving entity") shall be a company
organized and existing under the laws of the Federative Republic of Brazil or
any State or political subdivision thereof; (b) the surviving entity shall
expressly assume all of the obligations of the Company under the Notes and the
Indenture and shall execute a supplemental indenture to effect such assumption
which supplemental indenture shall be delivered to the Trustee and shall be in
form reasonably satisfactory to the Trustee; (c) immediately after giving effect
to such transaction or series of transactions on a pro forma basis (including,
without limitation, any Indebtedness incurred or anticipated to be incurred in
connection with or in respect of such transaction or series of transactions),
the Company or the surviving entity (assuming such surviving entity's assumption
of the Company's obligations under the Notes and the Indenture), as the case may
be, would be able to incur US$1.00 of Indebtedness under the proviso of the
covenant "Limitation on Additional Indebtedness and Preferred Stock of
Restricted Subsidiaries"; (d) immediately after giving effect to such
transaction or series of transactions on a pro forma basis (including, without
limitation, any Indebtedness incurred or anticipated to be incurred in
connection with or in respect of such transaction or series of transactions), no
Default shall have occurred and be continuing; (e) each Guarantor shall have
delivered a written instrument in form satisfactory to the Trustee confirming
its Guarantee; and (f) the Company or
 
                                       76
<PAGE>
the surviving entity, as the case may be, shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel stating that such transaction or
series of transactions, and, if a supplemental indenture is required in
connection with such transaction or series of transactions to effectuate such
assumption, such supplemental indenture complies with this covenant and that all
conditions precedent in the Indenture relating to the transaction or series of
transactions have been satisfied. In addition to the foregoing, in the case of
any merger, consolidation or combination involving a Guarantor as a result of
which such Guarantor's Guarantee is not released as provided under "Certain
Covenants--Issuance of Guarantees by Material Restricted Subsidiaries; Release
of Guarantees," such Guarantor or the resulting, surviving or transferee person
(if other than such Guarantor) shall expressly assume all of such Guarantor's
obligations under its Guarantee and the Indenture and shall execute a
supplemental indenture to effectuate such assumption, which supplemental
indenture shall be delivered to the Trustee and shall be in form and substance
satisfactory to the Trustee.
 
    The Indenture provides that upon any consolidation, combination or merger or
any transfer of all or substantially all of the assets of a person subject to,
and in accordance with, the foregoing, the surviving entity shall succeed to,
and be substituted for, and may exercise every right and power of the Company or
such Guarantor, as the case may be, under the Indenture and the applicable
Guarantee with the same effect as if such surviving entity had been named as
such; provided that, solely for purposes of computing Cumulative Adjusted
Available Cash Flow for purposes of clause (iii) of the first paragraph of the
covenant "Limitation on Restricted Payments" above, the Cumulative Adjusted
Available Cash Flow of any persons other than the Company and the Restricted
Subsidiaries shall only be included for periods subsequent to the effective time
of such merger, consolidation, combination or transfer of assets.
 
    The Indenture provides that, for all purposes of the Indenture and the Notes
(including the provisions of this covenant and the covenants "Limitation on
Additional Indebtedness and Preferred Stock of Restricted Subsidiaries,"
"Limitation on Restricted Payments" and "Limitation on Liens"), Subsidiaries of
any Surviving Entity will, upon such transaction or series of transactions,
become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant
to the covenant described under "Limitation on Designations of Unrestricted
Subsidiaries" and all Indebtedness, and all Liens on property or assets, of the
Company and the Restricted Subsidiaries immediately prior to such transaction or
series of transactions will be deemed to have been incurred upon such
transaction or series of transactions.
 
    The meaning of the phrase "all or substantially all" as used above varies
according to the facts and circumstances of the subject transaction, has no
clearly established meaning under relevant law and is subject to judicial
interpretation. Accordingly, in certain circumstances, there may be a degree of
uncertainty in ascertaining whether a particular transaction would involve a
disposition of "all or substantially all" of the assets of the Company, and
therefore it may be unclear whether the foregoing provisions are applicable.
 
EVENTS OF DEFAULT
 
    The following are Events of Default under the Indenture:
 
        (i) default in the payment of the principal of, or premium, if any, on
    the Notes when due, at maturity, upon redemption or otherwise (including
    pursuant to a Change of Control Offer or an Asset Sale Offer); or
 
        (ii) default in the payment of interest on the Notes when it becomes due
    and payable and continuance of such default for a period of 30 days or more;
    PROVIDED, HOWEVER, that a failure to pay interest (but not Additional
    Amounts) on the Notes in a timely manner through June 6, 2000 will
    constitute an immediate Event of Default under the Indenture, with no grace
    or cure period; or
 
                                       77
<PAGE>
       (iii) (a) failure to comply with the covenant described under
    "Consolidation, Merger, Sale of Assets, Etc." or (b) failure to comply with
    any other covenant or other term in the Indenture (other than those
    specified in clause (i) or (ii)) and, such default continues for a period of
    45 days after notice to the Company thereof by the Trustee or to the Company
    and the Trustee by holders of at least 25% of the aggregate principal amount
    of the Notes then outstanding; or
 
        (iv) (a) failure to pay, following any applicable grace period, any
    installment of principal due (whether at maturity or otherwise) under one or
    more classes or issues of Indebtedness in an aggregate principal amount of
    US$5,000,000 (or, to the extent non-U.S. dollar denominated, the U.S. Dollar
    Equivalent of such amount) or more or (b) failure by the Company or any
    Restricted Subsidiary to perform any other term, covenant, condition or
    provision of one or more classes or issues of indebtedness in an aggregate
    principal amount of the equivalent of US$5,000,000 (or, to the extent
    non-U.S. dollar denominated, the U.S. Dollar Equivalent of such amount) or
    more and, in the case of this clause (b), such failure results in an
    acceleration of the maturity thereof; PROVIDED, that, in the case of a
    termination or expiration of an Interest Rate Protection Obligation or
    Currency Agreement requiring that the monetary liability thereunder be paid,
    no Event of Default shall occur if such payment is made within 30 days after
    such payment is due; or
 
        (v) one or more judgments, orders or decrees for the payment of money
    shall be entered in an amount or amounts of US$5,000,000 (or, to the extent
    non-U.S. dollar denominated, the U.S. Dollar Equivalent of such amount) or
    more, either individually or in the aggregate, against the Company or any
    Restricted Subsidiary or any of their respective properties and shall not be
    discharged or satisfied and there shall have been a period of 60 days during
    which a stay of enforcement of such judgment, order or decree, by reason of
    pending appeal or otherwise, shall not be in effect; or
 
        (vi) certain events of bankruptcy, dissolution, insolvency,
    reorganization, administration, sequestration or similar proceedings
    involving the Company or a Material Restricted Subsidiary of the Company; or
 
       (vii) there shall have occurred any seizure, compulsory acquisition,
    expropriation or nationalization of substantially all of the assets of the
    Company and the Restricted Subsidiaries, taken as a whole; or
 
      (viii) the Company asserts or admits in writing that the Pledge Agreement
    is unenforceable or is not in full force and effect; or
 
        (ix) any Guarantee ceases to be in full force and effect or is declared
    null and void or any Guarantor denies that it has any further liability
    under any Guarantee or gives notice to that effect (other than by reason of
    the termination of the Indenture or the release of any Guarantee in
    accordance with the Indenture).
 
    If an Event of Default (other than an Event of Default specified in clause
(vi) with respect to the Company or clause (vii)) occurs and is continuing, then
the Trustee or the holders of at least 25% in aggregate principal amount of the
outstanding Notes may by written notice, and the Trustee upon request of the
holders of not less than 25% in principal amount of the outstanding Notes shall,
declare the principal of all the outstanding Notes to be due and payable
immediately, together with all accrued and unpaid interest and premium, if any,
thereon. Upon any such declaration, such amount shall become due and payable
immediately. If an Event of Default specified in clause (vi) with respect to the
Company or clause (vii) occurs and is continuing, then such amount will IPSO
FACTO become and be immediately due and payable without any declaration or other
act on the part of the Trustee or any holder.
 
    After a declaration of acceleration or any IPSO FACTO acceleration pursuant
to clauses (vi) or (vii), the holders of a majority in aggregate principal
amount of outstanding Notes may, by notice to the Trustee, rescind such
declaration of acceleration and its consequences if all existing Events of
Default, other than nonpayment of the principal of, and accrued and unpaid
interest on, the Notes that has become due solely
 
                                       78
<PAGE>
as a result of such acceleration, have been cured or waived and if the
rescission of acceleration would not conflict with any judgment or decree. The
holders of a majority in principal amount of the outstanding Notes also have the
right to waive past defaults under the Indenture, except a default in the
payment of the principal of, or any interest on, any outstanding Note, or in
respect of a covenant or a provision that cannot be modified or amended without
the consent of all holders of Notes.
 
    No holder of any of the Notes has any right to institute any proceeding with
respect to the Indenture or any remedy thereunder, unless the holders of at
least 25% in principal amount of the outstanding Notes have made written
request, and offered reasonable indemnity, to the Trustee to institute such
proceeding as Trustee, the Trustee has failed to institute such proceeding
within 45 days after receipt of such notice and the Trustee has not within such
45-day period received directions inconsistent with such written request by
holders of a majority in principal amount of the outstanding Notes. Such
limitations do not apply, however, to a suit instituted by a holder of a Note
for the enforcement of the payment of the principal of, premium, if any, or any
accrued and unpaid interest on, such Note on or after the respective due dates
expressed in such Note.
 
    During the existence of an Event of Default, the Trustee is required to
exercise such rights and powers vested in it under the Indenture and use the
same degree of care and skill in its exercise thereof as a prudent person would
exercise under the circumstances in the conduct of such person's own affairs.
Subject to the provisions of the Indenture relating to the duties of the
Trustee, if an Event of Default shall occur and be continuing, the Trustee is
not under any obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the holders unless such holders
shall have offered to such Trustee reasonable security or indemnity. Subject to
certain provisions concerning the rights of the Trustee, the holders of a
majority in principal amount of the outstanding Notes have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to the Trustee, or exercising any trust, or power conferred on the Trustee.
 
    The Indenture provides that the Trustee will, within 30 days after the
occurrence of any Default, give to the holders of the Notes notice of such
Default known to it, unless such Default shall have been cured or waived;
PROVIDED that, except in the case of a Default in payment of principal of or
premium, if any, on any Note when due or in the case of any Default in the
payment of any interest on the Notes or in the case of any Default arising from
the occurrence of any Change of Control, the Trustee shall be protected in
withholding such notice if it determines in good faith that the withholding of
such notice is in the interest of such holders.
 
    The Company is required to furnish to the Trustee annually a statement as to
compliance with all conditions and covenants under the Indenture.
 
SATISFACTION AND DISCHARGE OF THE INDENTURE; DEFEASANCE
 
    The Company and the Guarantors may terminate their obligations under the
Indenture, when (1) either: (A) all Notes theretofore authenticated and
delivered have been delivered to the Trustee for cancellation, or (B) all such
Notes not theretofore delivered to the Trustee for cancellation will become due
and payable (a "Discharge") under irrevocable arrangements satisfactory to the
Trustee for the giving of notice of redemption by the Trustee in the name, and
at the expense, of the Company, and the Company has irrevocably deposited or
caused to be deposited with the Trustee funds in an amount sufficient to pay and
discharge the entire indebtedness on the Notes, not theretofore delivered to the
Trustee for cancellation, for principal of, premium, if any, on and interest to
the date of deposit or maturity or date of redemption; (2) the Company has paid
or caused to be paid all other sums then due and payable under the Indenture by
the Company; and (3) the Company has delivered to the Trustee an officers'
certificate and an opinion of counsel, each stating that all conditions
precedent under the Indenture relating to the satisfaction and discharge of the
Indenture have been complied with.
 
                                       79
<PAGE>
    The Company may elect, at its option, to have its obligations discharged
with respect to the outstanding Notes ("legal defeasance"). Such defeasance
means that the Company will be deemed to have paid and discharged the entire
indebtedness represented by the outstanding Notes, except for (1) the rights of
holders of such Notes to receive payments in respect of the principal of and any
premium and interest on such Notes when payments are due, (2) the Company's
obligations with respect to such Notes concerning issuing temporary Notes,
registration of transfer of Notes, mutilated, destroyed, lost or stolen Notes
and the maintenance of an office or agency for payment and money for security
payments held in trust, (3) the rights, powers, trusts, duties and immunities of
the Trustee, and (4) the defeasance provisions of the Indenture. In addition,
the Company may elect, at its option, to have its obligations released with
respect to certain covenants in the Indenture, including covenants relating to
Asset Sales and a Change of Control ("covenant defeasance"), and any omission to
comply with such obligation shall not constitute a Default or an Event of
Default with respect to the Notes. In the event covenant defeasance occurs,
certain events (not including non-payment, bankruptcy and insolvency events)
described under "Events of Default" will no longer constitute an Event of
Default with respect to the Notes.
 
    In order to exercise either legal defeasance or covenant defeasance with
respect to outstanding Notes: (1) the Company must irrevocably have deposited or
caused to be deposited with the Trustee as trust funds in trust for the purpose

opinion of an internationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee to pay and

interest on such Notes on the maturity thereof or (if the Company has made
irrevocable arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name and at the expense of the Company) the

Indenture and such Notes; (2) in the case of legal defeasance, the Company shall
have delivered to the Trustee an opinion of U.S. counsel stating that, since the

income tax law, and based thereon such opinion shall confirm that, under then
applicable U.S. federal income tax law, the holders of such Notes will not
recognize gain or loss for U.S. federal income tax purposes as a result of the
deposit, defeasance and discharge to be effected with respect to such Notes and
will be subject to federal income tax on the same amount, in the same manner and
at the same times as would be the case if such deposit, defeasance and discharge
were not to occur; (3) in the case of covenant defeasance, the Company shall
have delivered to the Trustee an opinion of U.S. counsel to the effect that the

be the case if such deposit and covenant defeasance were not to occur; (4) the

after the date of such deposit (it being understood that this condition shall
not be deemed satisfied until after such 91st day); (6) such legal defeasance or
covenant defeasance shall not cause the Trustee to have a conflicting interest
within the meaning of the Trust Indenture Act (assuming all Notes were in
default within the meaning of such Act); (7) such defeasance or covenant
defeasance shall not result in a breach or violation of, or constitute a default
under, any other agreement or instrument to which the Company or any Guarantor
is a party or by which it is bound; (8) such legal defeasance or covenant
 
                                       80

such trust shall be registered under such Act or exempt from registration
thereunder; and (9) the Company shall have delivered to the Trustee an officers'
certificate and an opinion of counsel stating that all conditions precedent with

AMENDMENT AND WAIVERS
 
    From time to time the Company and the Guarantors when authorized by
resolutions of their respective Boards, and the Trustee, without the consent of
the holders of the Notes, may amend, waive or supplement the Indenture, the
Notes or the Guarantees for certain specified purposes, including, among other
things, curing ambiguities, defects or inconsistencies, to provide for the
assumption of the Company's obligations to holders of the Notes in the case of a
merger or consolidation, to make any change that would provide any additional
rights or benefits to the holders of the Notes, to add Guarantors with respect
to the Notes, to secure the Notes, maintaining the qualification of the
Indenture under the Trust Indenture Act or making any change that does not
adversely affect the rights of any holder. Other amendments and modifications of
the Indenture, the Notes or the Guarantees may be made by the Company and the
Guarantors and the Trustee with the consent of the holders of not less than a
majority of the aggregate principal amount of the outstanding Notes; PROVIDED
that no such modification or amendment may, without the consent of the holder of
each outstanding Note affected thereby, (i) reduce the principal amount of,
extend the fixed maturity of the Notes, or alter or waive the redemption
provisions of the Notes (other than, subject to clause (vii) below, provisions
relating to repurchase of Notes upon the occurrence of an Asset Sale or a Change
of Control), (ii) change the currency in which any Notes or the Guarantees or
any premium or the accrued interest thereon is payable, (iii) reduce the
percentage in principal amount outstanding of Notes who must consent to an

Indenture, the Notes or the Guarantees, (iv) impair the right to institute suit
for the enforcement of any payment on or with respect to the Notes or the

FOREIGN EXCHANGE RESTRICTIONS; CURRENCY INDEMNITY
 
    Payments in respect of the Notes or any Guarantee shall be made in United
States dollars as at the time of payment shall be legal tender for the payment
of public and private debts in that currency. In the event that on any payment
date in respect of the Notes or any Guarantee, any restrictions or prohibition
of access to the Brazilian foreign exchange market exists, the Company and each
Guarantor agree to pay all amounts payable under the Notes in U.S. dollars by
means of any legal procedure existing in Brazil (except commencing legal
proceedings against the Brazilian Central Bank), on any due date for payment
under the Notes. All costs and taxes payable in connection with the procedures
referred to in this covenant shall be borne by the Company and each Guarantor.
 
    U.S. dollars are the sole currency of account and payment for all sums
payable by the Company and the Guarantors under or in connection with the Notes,
including damages. Any amount received or recovered in a currency other than
U.S. dollars (whether as a result of, or of the enforcement of, a judgment or
order of a court of any jurisdiction, in the winding-up or dissolution of the
Company or any Guarantor or otherwise) by any holder of a Note in respect of any
sum expressed to be due to it from the
 
                                       81
<PAGE>
Company and the Guarantors shall only constitute a discharge to the Company and
the Guarantors to the extent of the U.S. dollar amount which the recipient is
able to purchase with the amount so received or recovered in that other currency
on the date of that receipt or recovery (or, if it is not practicable to make
that purchase on that date, on the first date on which it is practicable to do
so). If that U.S. dollar amount is less than the U.S. dollar amount expressed to
be due to the recipient under any Note, the Company and the Guarantors, jointly
and severally, shall indemnify it against any loss sustained by it as a result.
In any event, the Company and the Guarantors, jointly and severally, shall
indemnify the recipient against the cost of making any such purchase. For the
purposes of this paragraph, it will be sufficient for the holder of a Note to
certify in a satisfactory manner (indicating sources of information used) that
it would have suffered a loss had an actual purchase of U.S. dollars been made
with the amount so received in that other currency on the date of receipt or
recovery (or, if a purchase of U.S. dollars on such date had not been
practicable, on the first date on which it would have been practicable, it being
required that the need for a change of date be certified in the manner mentioned
above). This indemnity constitutes a separate and independent obligation from
other obligations of the Company and each Guarantor, shall give rise to a
separate and independent cause of action, shall apply irrespective of any
indulgence granted by any holder of a Note and shall continue in full force and
effect despite any other judgment, order, claim or proof for a liquidated amount
in respect of any sum due under any Note.
 
DISCHARGE AND INDEMNIFICATION
 
    Any payment to be made in respect of the Notes or the Guarantees by the
Company or any Guarantor to or to the order of a Paying Agent shall be in
satisfaction PRO TANTO of the obligations of the Company under the Notes. The
Company will indemnify the Holders against any failure on the part of any Paying
Agent to pay any sum due in respect of the Notes and will pay such sum to the
Trustee on demand. This indemnity constitutes a separate and independent
obligation from the other obligations of the Company under the Notes, will give
rise to a separate and independent cause of action, will apply irrespective of
any waiver granted by the Trustee and/or any holder of Notes and will continue
in full force and effect despite any judgment, order, claim, or proof for a
liquidated amount in respect of any sum due under the Indenture, the Notes or
any judgment or order.
 
REGARDING THE TRUSTEE AND PAYING AGENTS
 
    The Chase Manhattan Bank serves as Trustee and Co-Paying Agent under the
Indenture and as Pledgee under the Pledge Agreement. Chase Japan will serve as
Principal Paying Agent. The Indenture provides that, except during the
continuance of an Event of Default, the Trustee thereunder will perform only
such duties as are specifically set forth in the Indenture. If an Event of
Default has occurred and is continuing, the Trustee will exercise such rights
and powers vested in it under the Indenture and use the same degree of care and
skill in its exercise as a prudent person would exercise under the circumstances
in the conduct of such person's own affairs.
 
    The Indenture and provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the Trustee thereunder,
should it become a creditor of the Company or a Guarantor, to obtain payment of
claims in certain cases or to realize on certain property received by it in
respect of any such claims, as security or otherwise. The Trustee is permitted
to engage in other transactions; PROVIDED that if it acquires any conflicting
interest (as defined herein) it must eliminate such conflict or resign.
 
GOVERNING LAW
 
    The Indenture, the Pledge Agreement, the Notes and the Guarantees will each
provide that such agreements will be governed by and construed in accordance
with laws of the State of New York without giving effect to principles of
conflicts of law, except that matters relating to the authorization by the
 
                                       82
<PAGE>
Company or any Guarantor of the Indenture, the Pledge Agreement, the Notes and
the Guarantees shall be governed by the applicable laws of the Federative
Republic of Brazil.
 
ENFORCEABILITY OF JUDGMENTS
 
    Service of process upon the Company or any Guarantor in an action (other
than an insolvency, liquidation or bankruptcy proceeding or any other proceeding
in the nature of an in rem or quasi in rem proceeding) to enforce their
obligations under the Indenture, the Notes and the Guarantees may be obtained
within the United States by service upon CT Corporation System. See "Risk
Factors--Factors Relating to Brazil--Enforceability of Judgments." Since
substantially all of the assets of the Company, the Guarantors and their
respective subsidiaries are outside the United States, any judgment obtained in
the United States against the Company or any Guarantor, including judgments with
respect to the payment of amounts owing with respect to the Notes or the
Guarantees, may not be collectible within the United States.
 
    Judgments for monetary claims obtained in U.S. courts arising out of or in
relation to the obligations of the Company and the Guarantors under the
Indenture and the Notes will be enforceable in Brazil, provided that such
judgment has been previously confirmed by the Brazilian Federal Supreme Court.
In order to be confirmed by the Brazilian Federal Supreme Court, such foreign
judgment must meet the following conditions: (a) it must comply with all
formalities required for its enforceability under the laws of the country where
it was issued; (b) it must have been given by a competent court after the proper
service of process on the parties; (c) it must not be subject to appeal; (d) it
must not offend Brazilian national sovereignty, public policy or good morals;
and (e) it must be duly authenticated by a competent Brazilian consulate and be
accompanied by a sworn translation thereof into Portuguese. Notwithstanding
foregoing, no assurance can be given that such confirmation will be obtained,
that process described above can be conducted in a timely manner or that a
Brazilian court will enforce such monetary judgment. See "Enforceability of
Civil Liabilities."
 
    Any judgment obtained against the Company or any Guarantor in a court in
Brazil under any Note or under the Indenture will be expressed in the Brazilian
currency equivalent to the U.S. dollar amount of such sum at the commercial
exchange rate of the date at which such judgment is obtained, and such Brazilian
currency amount will be corrected in accordance with the exchange variation
until the judgment holder receives effective payment.
 
CERTAIN BANKRUPTCY LAW CONSIDERATIONS
 
    Brazilian bankruptcy laws grant extensive powers to the courts. Brazilian
Bankruptcy Law (Decree-law No. 7,661, of June 21, 1945, the "Brazilian
Bankruptcy Law") establishes two different proceedings for the resolution of
debts of commercial companies which are insolvent or do not pay their
obligations when due: the bankruptcy proceeding ("falencia") and the
reorganization proceeding ("concordata"). Both proceedings apply to all
unsecured creditors of a company which is declared bankrupt or which is under a
reorganization proceeding. In the event that the Company or any Guarantor is
declared bankrupt or enters into a concordata, the Notes will be considered
general unsecured indebtedness of the Company or such Guarantor and therefore
will be subject to such proceedings.
 
    Under a bankruptcy proceeding (essentially a liquidation proceeding),
payments in respect of the Notes or the Guarantees will be subject to an order
of priority. Generally, Brazilian Bankruptcy Law and other applicable rules
establish that claims of employees for wages or indemnity and tax claims have
priority over other claims against the bankrupt estate. Other claims are subject
to the following order of priority: (a) secured credits, (b) credits with
special privileges over certain assets, (c) credits with general privilege and
(d) unsecured credits. Credits in foreign currency are converted into Brazilian
currency on the date the Company is declared bankrupt and are not subject to
adjustment in accordance with the
 
                                       83
<PAGE>
exchange variation. Such amount in Brazilian currency must be monetarily
adjusted to account for inflation (in accordance with the rules applicable from
time to time) and bears no interest.
 
    The general rule under Brazilian Bankruptcy Law is that all of the assets of
a company in bankruptcy proceedings, including those in the possession of third
parties under a deposit or pledge must be collected to the bankrupt estate. In
the event the Company is declared bankrupt or enters into a concordata,
Brazilian Bankruptcy Law provides that the Pledged Securities be collected along
with the other assets of the Company. The credits due in connection with the
Pledged Securities shall be considered secured credits and shall have priority
in the payments made under the bankruptcy proceedings.
 
    Under a concordata proceeding, which is a protection available under the
Brazilian Bankruptcy Law for commercial companies experiencing financial
distress to avoid the declaration of bankruptcy, the Company's or Guarantors'
unsecured credits existing at the time the concordata is declared are
rescheduled for one of the periods defined in the law which in virtually all
cases is 24 months (in which event 40% of the debt must be paid in the first
year). The benefit may be given by the court without any prior consultation with
or manifestation by the creditors, so long as the beneficiary demonstrates,
INTER ALIA, that its assets are worth at least 50% of its unsecured
indebtedness. The concordata proceeding has the following basic characteristics:
(i) it only affects unsecured creditors; (ii) it does not affect the day-to-day
management of the Company, the other commercial obligations of the Company and
the obligations assumed after the date on which the concordata is declared;
(iii) amounts due in foreign currency subject to the concordata are converted
into local currency on the date on which the concordata is accepted by the court
and are not subject to adjustment in accordance with the exchange variation;
(iv) amounts due under the concordata, either in local currency or converted
into local currency, must be monetarily adjusted to account for inflation (in
accordance with the rules applicable from time to time) and bear interest at the
rate of 12% per annum; and (v) a company under concordata which fails to meet
its rescheduled obligations will be declared bankrupt.
 
CONSENT TO JURISDICTION AND SERVICE
 
    The Indenture provides that the Company and each Guarantor will appoint CT
Corporation System as its agent for service of process in any suit, action or
proceeding with respect to the Indenture, the Notes and the Guarantees and for
actions brought under federal or state securities laws brought in any Federal or
state court located in the City of New York and will submit to such
jurisdiction. See "Enforceability of Civil Liabilities."

                               TAX CONSIDERATIONS
 
BRAZIL
 
    The following is a summary of the material Brazilian income tax consequences
to the Company in connection with the sale and repayment of the Notes (including
any interest thereon) and to beneficial owners of the Notes that are
non-residents of Brazil in connection with the purchase, ownership and
disposition of such Notes. This summary is limited to the Company and to
non-residents of Brazil which acquire the Notes at the issue price from the
Initial Purchasers, and does not address investors who purchase Notes at a
premium or market discount. In addition, this summary is based on the Brazilian
tax regulations as presently in effect and does not take into account possible
future changes in such tax laws. Prospective purchasers of the Notes are advised
to consult their tax advisers as to the consequences of a purchase and sale of
the Notes.
 
    Individuals domiciled in Brazil and Brazilian companies are taxed in Brazil
on the basis of their worldwide income (which includes earnings of Brazilian
companies' foreign subsidiaries, branches and affiliates). The income of
non-Brazilian residents in general are taxed in Brazil only when derived from
Brazilian sources. Interest, fees, commissions and any other income (which for
the purposes of this paragraph includes any deemed income on the difference
between the issue price of the Notes and the price at which the Notes are
redeemed ("original discount")) payable by a Brazilian obligor to an individual,
company, entity, trust or organization domiciled outside Brazil is subject to
income tax withheld at source. The rate of withholding with respect to debt
obligations is 15% or such other lower rate as provided for in an applicable tax
treaty between Brazil and such other country where the recipient of the payment
has its domicile. Notwithstanding the foregoing, with respect to the tax events
which take place during the calendar year of 1997, the applicable withholding
income tax rate for interest, commissions, expenses and discounts, payable to
persons or entities domiciled abroad, arising from negotiable instruments such
as the Notes, was reduced to zero, pursuant to Provisional Measure No. 1.563, of
December 31, 1996, published in the Official Gazette of January 2, 1997 and
republished in the Official Gazette of April 24, 1997, which restricts such
income tax reductions to negotiable instruments placed abroad with the previous
approval of the Central Bank, with a minimum average amortization term of at
least 96 months. As a result, since the Notes have an original maturity in
excess of 96 months, such reduction will apply to payments of interest and other
income with respect to the Notes paid during the fiscal year of 1997. It is not
certain whether such reduction will continue to apply after 1997. In any event,
if any Notes are redeemed prior to the maturity date, such reduction will not
apply and upon any such redemption the Brazilian withholding tax will be applied
on the amount of interest (including original discount), fees and commissions
paid on such Notes from the date of issue through the date of redemption. See
"Description of the Notes--Additional Amounts" and "Description of the
Notes--Brazilian Central Bank Consent for Optional and Mandatory Redemption of
Notes."
 
    Since the Principal Paying Agent is located in Japan and payment to the
Principal Paying Agent discharges the obligations of the Company to make
payments in respect of the Notes, if interest and other income with respect to
the Notes were to become subject to Brazilian withholding income tax (as
determined in the preceding paragraph), such tax would be imposed at a rate of
only 12.5% under the current tax treaty in effect between Brazil and Japan. In
any event, under the terms of the Notes, the Company is required to gross-up
Noteholders for Brazilian withholding tax, subject to certain exceptions. See
"Description of the Notes--Additional Amounts." The Company has the right to
redeem the Notes at par in the event of certain increases in Brazilian
withholding tax to a rate in excess of 15%. See "Description of the
Notes--Redemption for Changes in Withholding Taxes."
 
    Any earnings or capital gains made abroad as a result of a transaction
between two non-residents of Brazil are not subject to tax in Brazil. However,
gains realized by a non-resident on the disposition of the Notes inside Brazil,
or to a Brazilian resident outside of Brazil, will be subject to Brazilian tax.
 
                                       99

    Pursuant to Decree 1,815 of February 8, 1996, REAIS resulting from the
conversion of the proceeds received by a Brazilian borrower from a foreign
currency loan (including those in connection with the issue of bonds or notes)
are subject to a tax on exchange transactions. Under Article 4 of Decree
1,815/96, the Minister of Finance is empowered to establish the applicable tax
rate, which was set by means of Portaria 241 of October 31, 1996. Portaria 241
was revoked by Portaria 85, enacted on April 24, 1997, which reduced to zero the
IOF rate applicable on the REAIS. The IOF tax is currently regulated by Decree
No. 2,219 dated May 2, 1997. Under Law 8,894 of June 21, 1994, such tax rate may
be increased up to 25%. In any event, the tax burden falls upon the Brazilian
borrower, not upon foreign creditors such as the holders of the Notes and will
be deducted from the proceeds of the issue of the Notes. See "Description of the
Notes--Additional Amounts."
 
    On August 15, 1996, the Brazilian Congress approved Constitutional Amendment
No. 12 creating a new temporary tax, the CONTRIBUICAO PROVISORIA SOBRE
MOVIMENTACAO FINANCEIRA ("CPMF"). Based on such Amendment, Law No. 9,311 of
October 24, 1996 was enacted, determining the creation of the CPMF tax. Under
Law No. 9,311/96 all financial debt and money transfers effected on or after
January 23, 1997 will be subject to the assessment of the CPMF tax at the rate
of 0.20%. Funds arising from the collection of the CPMF tax will be applied only
in the public health system.
 
    There is no stamp, transfer or other similar tax in Brazil with respect to
the transfer, assignment or sale or any debt instrument outside Brazil
(including the Notes).
 
UNITED STATES
 
    FEDERAL INCOME TAXATION
 
    The following is a summary of certain U.S. federal income tax consequences
associated with the purchase, ownership and disposition of a Note. This summary
does not discuss all of the tax consequences that may be relevant to certain
types of investors subject to special treatment under the U.S. federal income
tax laws (such as individual retirement accounts and other tax-deferred
accounts, securities broker-dealers, life insurance companies, tax-exempt
organizations and foreign persons, or to persons whose "functional currency" is
other than the U.S. dollar or to persons which hold Notes as part of a
"straddle" or "conversion transaction" or otherwise as part of a "synthetic
asset") and is limited to investors which hold Notes as capital assets. In
addition, this summary is limited to initial holders that acquire the Notes at
the issue price from the Initial Purchasers. This summary is based on the
Internal Revenue Code of 1986, as amended (the "Code"), final, temporary and
proposed Treasury regulations thereunder, revenue rulings, court cases, and
other legal authorities as now in effect (or proposed) and as currently
interpreted, and does not take into account possible changes in such tax laws or
other legal authorities or such interpretations. No rulings on any of the issues
discussed below will be sought from the U.S. Internal Revenue Service (the
"IRS").
 
    For purposes of this discussion, a "U.S. Holder" is an individual who is a
citizen or resident of the United States, a corporation, partnership or other
entity created under the laws of the United States or any political subdivision
thereof, an estate that is subject to United States federal income taxation
without regard to the source of income, or a trust if a United States court is
able to exercise primary supervision over the administration of that trust and
one or more United States fiduciaries have the authority to control all
substantial decisions of such trust.
 
    PROSPECTIVE PURCHASERS OF THE NOTES ARE ADVISED TO CONSULT THEIR TAX
ADVISERS AS TO THE CONSEQUENCES OF A PURCHASE AND SALE OF NOTES, INCLUDING,
WITHOUT LIMITATION, (I) THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR NON-
U.S. TAX LAWS TO WHICH THEY MAY BE SUBJECT, AND OF ANY LEGISLATIVE OR
ADMINISTRATIVE CHANGES IN LAW, (II) THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF
THE ISSUER'S DEDUCTION OF BRAZILIAN TAXES AND OTHER AMOUNTS (AND OF THE PAYMENT
BY THE ISSUER OF ADDITIONAL AMOUNTS WITH RESPECT THERETO) WITH RESPECT TO
PAYMENTS

ON THE NOTES, (III) THE AVAILABILITY FOR U.S. FEDERAL INCOME TAX PURPOSES OF A
CREDIT OR DEDUCTION FOR BRAZILIAN TAXES OR OTHER AMOUNTS AND (IV) THE
CONSEQUENCES OF PURCHASING THE NOTES AT A PRICE OTHER THAN THE ISSUE PRICE.
 
    TAX CONSIDERATIONS APPLICABLE TO HOLDING NOTES
 
    TAXATION OF INTEREST AND ADDITIONAL AMOUNTS ON NOTES.  Interest on the Notes
and additional amounts relating thereto (I.E., without reduction for any
Brazilian withholding taxes) will be taxable to a U.S. Holder as ordinary income
at the time it accrues or is received in accordance with the U.S. Holder's
method of accounting for tax purposes.
 
    A U.S. Holder will treat the gross amount of interest and Additional Amounts
relating thereto (I.E., without reduction for any Brazilian withholding taxes,
if any) as ordinary interest income in respect of the Notes. If the IRS were to
successfully contend that a sufficiently large portion of the purchase price
should not be allocated to the Notes, the Notes would bear OID for U.S. federal
income tax purposes. U.S. Holders of Notes would be required to accrue in income
as additional interest (whether such holder was a cash or accrual taxpayer) in
each taxable year during which such U.S. holder held such Note, a portion of the
OID. The amount of OID on a Note would be the excess of its "stated redemption
price at maturity" over the Note's "issue price." In the event of a reallocation
of purchase price, a Note's "issue price" would be the portion of the purchase
price allocated to such Note and its "stated redemption price at maturity" would
generally be its stated principal amount. The amount of OID taken into account
in a particular year would be calculated under the constant yield to maturity
method. The effect of the OID rules, generally, would be that U.S. Holders would
recognize interest income in each year equal to the excess of the product of (i)
the yield to maturity on the Notes and (ii) the adjusted issue price over the
interest payments on the Notes. Generally, the adjusted issue price of the Notes
will be its issue price increased by previously accrued OID. Under this method,
the amount of OID included in the income of a U.S. Holder in early years would
be less than the includible amount in later years.
 
    Pursuant to applicable OID rules, the possibility that Additional Amounts
may be payable in respect of Brazilian withholding taxes on interest payments
could subject the Notes to the rules applicable to contingent payment debt
instruments, regardless of whether or not Brazil actually imposes such a
withholding tax. The Company intends to take the position, based on advice that
it has received from Brazilian counsel, that such rules should not apply to the
Notes. However, the IRS could challenge that position, and if it were to
successfully do so, gain realized by U.S. Holders with respect to the Notes
could be recharacterized as ordinary income rather than capital gain and,
therefore, at present U.S. federal income tax rates, subject to higher tax rates
for U.S. Holders who are individuals. The application of those rules could also
result in an unfavorable mismatch of income and deduction/foreign tax credit for
U.S. Holders. PROSPECTIVE U.S. HOLDERS SHOULD CONTACT THEIR OWN TAX ADVISORS
REGARDING THE APPLICATION OF THE OID RULES TO THE NOTES.
 
    The calculation of foreign tax credits and, in the case of a U.S. Holder
that elects to deduct foreign taxes, the availability of deductions, involves
the application of rules that depend on a U.S. Holder's particular
circumstances. U.S. Holders should consult their own tax advisers regarding the
availability of foreign tax credits and the treatment of additional amounts.
 
    SALE, EXCHANGE OR OTHER DISPOSITION OF NOTES.  A U.S. Holder will generally
recognize gain or loss upon the sale, exchange, retirement or other disposition
of Notes equal to the difference between the amount realized on the sale,
exchange or other disposition of such Note and the U.S. Holder's adjusted tax
basis in the Notes. Such gain or loss generally would be capital gain or loss,
and would be long-term if the Notes were held more than one year.
 
    REGISTRATION AND EXCHANGE OF NOTES.  Neither the Exchange Offer nor the
filing of a Notes Shelf Registration Statement as described under "Exchange
Offer; Notes Registration Rights" should result in a
 
                                      101
<PAGE>
taxable event to the Company or any U.S. Holder since there would be no material
alteration in the terms of the Notes.
 
    Under certain circumstances, Additional Interest shall become payable in
cash with respect to the applicable Notes. See "Exchange Offer; Notes
Registration Rights." This rate increase should not result in a deemed taxable
exchange of the Notes for Exchange Notes.
 
    EFFECT OF BRAZILIAN WITHHOLDING TAXES.  It is believed that payments with
respect to a Note will not be subject to Brazilian withholding tax during the
fiscal year of 1997 unless the Note is redeemed prior to June 6, 2005. After
1997 such payments may be subject to Brazilian withholding tax at a rate of up
to 15%. See "Tax Considerations--Brazil." In the case of any Note which is so
redeemed, withholding taxes in respect of interest previously paid may be
imposed by Brazil at the time of redemption. Any Brazilian tax withheld
generally will be treated as a foreign income tax that U.S. Holders may elect to
deduct in computing their taxable income or, subject to the limitations on
foreign tax credits generally, credit against their U.S. federal income tax
liability. No such deduction or credit will be available to the extent Brazil
pays a subsidy to a U.S. Holder, a related person or the Company, the amount of
which is determined (directly or indirectly) by reference to the amount of the
withholding tax. While Brazil does not have a program or policy of paying such
subsidies at present, it has had programs of that nature in the past and could
implement such programs again in the future. For purposes of determining a U.S.
Holder's United States foreign tax credit, gain or loss on the sale, redemption
or other taxable disposition of a Note will generally constitute United States
source income. Interest (including Brazilian withholding taxes imposed on
payments on a Note and Brazilian withholding taxes imposed with respect to any
Additional Amounts payable by the issuer) will generally constitute non-United
States source income. Such interest will generally constitute passive income.
However, if a Note is redeemed prior to June 6, 2005, and payments with respect
to the Note are subject to Brazilian withholding tax of five percent or more,
the IRS might retroactively treat interest paid with respect to the Note as high
withholding tax interest. In any event, a U.S. Holder may have insufficient
foreign source income to utilize fully any foreign tax credit attributable to
such withholding taxes that could otherwise be utilized (but such withholding
taxes may instead be deductible by the U.S. Holder). A U.S. Holder may be
required to provide the IRS with a certified copy of the receipt evidencing
payment of withholding tax imposed in respect of payments on the Notes (a
"Certified Copy") in order to claim a foreign tax credit in respect of such
withholding tax. A U.S. Holder (or its agent) may obtain a Certified Copy by
providing written demand therefor to the Principal Paying Agent. The Principal
Paying Agent will contact the issuer, which will provide such Certified Copy to
the Principal Paying Agent for prompt forwarding to the relevant U.S. Holder.
The issuer will attach to each Certified Copy a certificate stating (x) that the
amount of withholding tax evidenced by the Certified Copy was paid in connection
with payments in respect of the principal amount of notes then outstanding and
(y) the amount of such withholding tax paid per US$1,000 of principal amount of
the Notes.

                              PLAN OF DISTRIBUTION
 
    Each broker-dealer that receives New Notes for its own account in connection
with the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes if such
Old Notes were acquired as a result of market-making activities or other trading
activities. The Company has agreed that for a period of 180 days after the
Expiration Date, it will make this Prospectus, as amended or supplemented,
available to any broker-dealer that requests such documents in the Letter of
Transmittal, for use in connection with any such resale. In addition, until
           , 1997 (90 days after the date of this Prospectus), all dealers
effecting transactions in the New Notes may be required to deliver a prospectus.
 
    The Company will not receive any proceeds from any sale of New Notes by
broker-dealers. New Notes received by broker-dealers for their own account in
connection with the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the New Notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or at negotiated prices. Any such resale may be
made directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers on any such New Notes. Any broker-dealer
that resells New Notes that were received by it for its own account in
connection with the Exchange Offer and any broker or dealer that participates in
a distribution of such New Notes may be deemed to be an "underwriter" within the
meaning of the Securities Act, and any profit on any such resale of New Notes
and any commissions or concessions received by any such persons may be deemed to
be underwriting compensation under the Securities Act. The Letter of Transmittal
states that by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Shareholders
PAGING NETWORK DO BRASIL S.A.
Sao Paulo, Brazil
 
    We have audited the accompanying balance sheet of Paging Network do Brasil
S.A. (a development stage company) (formerly Warburg Paging do Brasil Ltda.) as
of December 31, 1996, and related statements of operations, shareholders' equity
(deficit) and cash flows for the period April 17, 1996 (inception) through
December 31, 1996. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Paging Network do Brasil
S.A. (a development stage company) as of December 31, 1996 and the results of
its operations and its cash flow for the period April 17, 1996 (inception)
through December 31, 1996, in conformity with generally accepted accounting
principles in the United States.

1. ORGANIZATION
 
    Paging Network do Brasil S.A. (formerly Warburg Paging do Brasil Ltda., the
"Company") is a start-up operation that was formed on April 7, 1996 through an
investment by Warburg, Pincus Ventures, L.P. During 1997, the Company plans to
initially provide paging services in Sao Paulo, where it has begun building
transmission stations, and simultaneously plans for expansion into additional
Brazilian markets.
 
    In October 1996, the Company increased its capital to approximately
$5,500,000 and in December 1996, through the incorporation of three new
shareholders, received approximately $15,000,000 of additional capital. In
December 1996, the Company changed its name from Warburg Paging do Brasil Ltda.
to Paging Network do Brasil Ltda. and then to Paging Network do Brasil S.A.
following a change in its legal formation from a limited liability company
(Ltda.) to a closed corporation (S.A.), at which time common stock in the
limited liability company was exchanged for common and redeemable preferred
stock in the Company.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    The financial statements have been prepared in accordance with generally
accepted accounting principles in the United States in U.S. dollars.
 
    The Company's significant accounting policies are as follows:
 
FOREIGN CURRENCY TRANSLATION
 
    The financial statements were translated from Brazilian reais to U.S.
dollars in accordance with the provisions of Statement of Financial Accounting
Standards No 52 as it applies to entities operating in highly inflationary
economies.
 
    Pager inventories, fixed assets and intangibles and the related income
statement accounts are remeasured at exchange rates in effect when the assets
were acquired or the liabilities were incurred. All other assets and liabilities
are remeasured at period end exchange rates, and all other income and expense
items are remeasured at average exchange rates prevailing during the period.
Remeasurement adjustments are included in exchange and translation gains
(losses).
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
REVENUE RECOGNITION
 
    The Company recognizes revenue under service, rental and maintenance
agreements with customers as the related services are performed. Advance
billings for services are deferred and recognized as revenue when earned. Sales
of pagers are recognized upon delivery. The Company will lease certain pagers
under operating leases. Substantially all of these leases will be on a
month-to-month basis.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES --(CONTINUED)
CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
INVENTORIES
 
    Inventories are valued at the lower of average cost, or market.
 
FIXED ASSETS
 
    Fixed assets are stated at cost. Depreciation is computed by the
straight-line method. Amortization of leasehold improvements is based on the
shorter of the useful life or lease term.
 
INCOME TAXES
 
    The Company adopted the liability method of accounting for income taxes
pursuant to Statement of Financial Accounting Standards No 109. Under this
method, deferred income taxes are recorded to reflect the tax consequences in
future years of temporary differences between the tax bases of the assets and
liabilities and the financial amounts for reporting purposes. The Company has
provided a valuation allowance to reduce deferred tax assets to their net
realizable value of zero. The Company's deferred tax assets arise principally
from start-up costs which for financial reporting purposes are expensed as
incurred; for tax and local statutory purposes they are capitalized and will be
amortized over five years when operations commence.
 
3. FIXED ASSETS
 
    Fixed assets at December 31, 1996 are comprised of the following:

1.  BASIS OF PRESENTATION
 
    The accompanying unaudited consolidated financial statements of Paging
Network do Brasil S.A. (the "Company") have been prepared in accordance with
generally accepted accounting principles for interim financial information.
Accordingly, they do not include all of the information and footnotes required
for complete financial statements. In the opinion of management, all adjustments
(consisting only of normal recurring accruals) considered necessary for a fair
presentation have been included. The results of operations for the three month
period are not necessarily indicative of the results for the entire year.
 
    From April 17, 1996 (inception) through December 31, 1996, the Company was
accounted for as a development stage company. Effective January 1, 1997, the
Company is no longer treated as a development stage company, as it commenced
earning revenues from operations in March 1997.

ITEM 22. UNDERTAKINGS.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted
 
                                      II-2
<PAGE>
by such director, officer or controlling person in connection with the
securities being registered, the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.
 
    The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
    The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in this Registration Statement when it became effective.
 
    The undersigned Registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
Registrant undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to the
reofferings by persons who may be deemed to be underwriters, in addition to the
information called for by the other Items of the applicable form.
 
    The undersigned Registrant hereby undertakes that every prospectus: (i) that
is filed pursuant to the immediately preceding paragraph or (ii) that purports
to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and
is used in connection with an offering of securities subject to Rule 415, will
be filed as a part of an amendment to the registration statement and will not be
used until such amendment is effective, and that, for purposes of determining
any liability under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

      assigned to them therein;

            (c)  all accounting terms not otherwise defined herein have

      shall be deemed in each case to be followed by the phrase "without
      limitation."

            Section 1.04 Form of Documents Delivered to Trustee.

            Upon any request or application by the Company or any Guarantor to
the Trustee to take any action under this Indenture, the Company or such
Guarantor, as the case may be, shall furnish to the Trustee (a) an Officers'
Certificate satisfactory to the Trustee stating that, in the opinion of the
signers, all conditions precedent, if any, provided for in this Indenture
relating to the proposed action have been complied with, (b) an Opinion of
Counsel satisfactory to the Trustee stating that, in the opinion of counsel, all
such conditions have been complied with and (c) where applicable, a certificate
or opinion by an accountant that complies with Section 314(c) of the Trust
Indenture Act.

            Each certificate and Opinion of Counsel with respect to compliance

            (a)  a statement that the person making such certificate or
      Opinion of Counsel has read such covenant or condition;


<PAGE>
                                      -35-


            (b) a brief statement as to the nature and scope of the examination
      or investigation upon which the statements contained in such certificate
      or Opinion of Counsel are based;

            (c) a statement that, in the opinion of such person, he has made

knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to the matters upon which his
certificate or opinion is based are erroneous. Any such certificate or opinion
of counsel may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the
Company or any Guarantor stating that the information with respect to such
factual matters is in the possession of the Company or any Guarantor, unless
such counsel knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to such matters are
erroneous.

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated, with
proper identification of each matter covered therein, and form one instrument.

waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such

to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution (as provided below in
subsection (b) of this Section 1.05) of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 6.01 hereof) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section.

            (b) The fact and date of the execution by any person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient.

            (c) The ownership of Securities shall be proved by the Security
Register.

            (d) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Security shall bind every future
Holder of the same Security or the Holder of every Security issued upon the
transfer thereof or in exchange therefor or in lieu thereof to the same extent
as the original Holder, in respect of anything done, suffered or omitted to be
done by the Trustee, any Paying Agent or the Company or any Guarantor in
reliance thereon, whether or not notation of such action is made upon such
Security.

            Section 1.06 Notices, etc., to the Trustee and the Company.

            Any request, demand, authorization, direction, notice, consent,
waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with:

            (a) the Trustee by any Holder or by the Company shall be sufficient
      for every purpose hereunder if made, 

<PAGE>
                                      -37-


      given, furnished or filed, in writing, to or with the Trustee at 450 West
      33rd Street, 15th Floor, New York, New York 10001, Attention:
      International Corporate Trust Division or at any other address previously
      furnished in writing to the Holders, the Company and the Guarantors by the
      Trustee; or

            (b) the Company by the Trustee or by any Holder shall be sufficient
      for every purpose (except as otherwise expressly provided herein)
      hereunder if in writing and mailed, first-class postage prepaid, to the
      Company addressed to it at Rua Alexandre Dumas, 1.711, Chacara Santa
      Antonio, Sao Paulo 04717-004 Brazil, Attention: Chief Executive Officer,
      or at any other address previously furnished in writing to the Trustee by
      the Company.

            Section 1.07 Notice to Holders; Waiver.

            Where this Indenture provides for notice to Holders of any event,
such notice shall be sufficiently given (unless otherwise expressly provided
herein) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at the address of such Holder as it appears in the
Security Register, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice. In any case where
notice to Holders is given by mail, neither the failure to mail such notice, nor
any defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Any notice when mailed
to a Holder in the aforesaid manner shall be conclusively deemed to have been
received by such Holder whether or not actually received by such Holder. Where
this Indenture provides for notice in any manner, such notice may be waived in
writing by the person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice. Waivers of
notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such
waiver.

            In case by reason of the suspension of regular mail service or by
reason of any other cause, it shall be impracticable to mail notice of any event
as required by any provision of this Indenture, then any method of giving such
notice as shall be satisfactory to the Trustee shall be deemed to be a
sufficient giving of such notice.

            Section 1.19 Agent for Service; Submission to Jurisdiction; Waiver
                         of Immunities.

            By the execution and delivery of this Indenture or any amendment or
supplement hereto, each of the Company and any Guarantor, (i) acknowledges that
it has, by separate written instrument, designated and appointed CT Corporation
System, currently located at 1633 Broadway, New York, New York 10019, as its
authorized agent upon which process may be served in any suit, action or
proceeding with respect to, arising out of, or relating to, the Securities, this
Indenture or any Guarantee that may be instituted in any Federal or state court
in the State of New York, The City of New York, the Borough of Manhattan, or
brought under Federal or state securities laws or brought by the Trustee
(whether in its individual capacity or in its capacity as Trustee hereunder),
and acknowledges that CT Corporation System has accepted such designation, (ii)
submits to the jurisdiction of any such court in any such suit, action or
proceeding, and (iii) agrees that service of process upon CT Corporation System
shall be deemed in every respect effective service of process upon the Company
or any such Guarantor, as the case may be, in any such suit, action or
proceeding. The Company and any Guarantor further agree to take any and all
action, including the execution and filing of any and all such documents and
instruments as may be necessary to continue such designation and appointment of
CT Corporation System in full force and effect so long as this Indenture shall
be in full force and effect; provided that the Company and any Guarantor may and
shall (to the extent CT Corporation System ceases to be able to be served on the
basis contemplated herein), by written notice to the Trustee, designate such
additional or alternative agents for service of process under this Section 1.19
that (i) maintains an office located in the Borough of Manhattan, The City of
New York in the State of New York, (ii) are either (x) counsel for the Company
and any Guarantor or (y) a corporate service company which acts as agent for
service of process for other persons in the ordinary course of its business and
(iii) agrees to act as agent for service of process in accordance with this
Section 1.19. Such notice shall identify the 

<PAGE>
                                      -41-


name of such agent for process and the address of such agent for process in the
Borough of Manhattan, The City of New York, State of New York. Upon the request
of any Holder, the Trustee shall deliver such information to such Holder.
Notwithstanding the foregoing, there shall, at all times, be at least one agent
for service of process for the Company and the Guarantors appointed and acting
in accordance with this Section 1.19.

            To the extent that the Company or any Guarantor has or hereafter may
acquire any immunity from jurisdiction of any court or from any legal process
(whether through service of notice, attachment prior to judgment, attachment in
aid of execution, execution or otherwise) with respect to itself or its
property, the Company and any Guarantor hereby irrevocably waives such immunity
in respect of its obligations under this Indenture and the Securities, to the
extent permitted by law.

            Section 1.20 Currency of Account; Conversion of Currency; Foreign
                         Exchange Restrictions.

            (a) U.S. dollars are the sole currency of account and payment for
all sums payable by the Company and the Guarantors under or in connection with
the Securities, the Guarantees or this Indenture, including damages. Any amount
received or recovered in a currency other than U.S. dollars (whether as a result
of, or of the enforcement of, a judgment or order of a court of any
jurisdiction, in the winding-up or dissolution of the Company and the
Guarantors, if any, or otherwise) by any Holder of the Securities in respect of
any sum expressed to be due to it from the Company and the Guarantors, if any,
shall only constitute a discharge to the Company and the Guarantors, if any, to
the extent of the U.S. dollar amount which the recipient is able to purchase
with the amount so received or recovered in that other currency on the date of
that receipt or recovery (or, if it is not practicable to make that purchase on
that date, on the first date on which it is practicable to do so). If that U.S.
dollar amount is less than the U.S. dollar amount expressed to be due to the
recipient under the Securities, the Company and the Guarantors, if any, shall,
jointly and severally, indemnify it against any loss sustained by it as a result
as set forth in Section 1.20(b). In any event, the Company and the Guarantors,
if any, shall, jointly and severally, indemnify the recipient against the cost
of making any such purchase. For the purposes of this Section 1.20, it will be
sufficient for the holder of a Security to certify in a satisfactory manner
(indicating sources of information used) that it would have suffered a loss had
an actual purchase of U.S. 

<PAGE>
                                      -42-


dollars been made with the amount so received in that other currency on the date
of receipt or recovery (or, if a purchase of U.S. dollars on such date had not
been practicable, on the first date on which it would have been practicable, it
being required that the need for a change of date be certified in the manner
mentioned above). The indemnities set forth in this Section 1.20 constitute
separate and independent obligations from other obligations of the Company and
the Guarantors, if any, shall give rise to a separate and independent cause of
action, shall apply irrespective of any indulgence granted by any Holder of the
Securities and shall continue in full force and effect despite any other
judgment, order, claim or proof for a liquidated amount in respect of any sum
due under the Securities.

            (b) The Company and each Guarantor, if any, covenant and agree that
the following provisions shall apply to conversion of currency in the case of
the Securities, the Guarantees and this Indenture:

            (i)(A) If for the purpose of obtaining judgment in, or enforcing the
      judgment of, any court in any country, it becomes necessary to convert
      into a currency (the "judgment currency") an amount due in any other
      currency (the "Base Currency"), then the conversion shall be made at the
      rate of exchange prevailing on the Business Day before the day on which
      the judgment is given or the order of enforcement is made, as the case may
      be (unless a court shall otherwise determine).

            (B) if there is a change in the rate of exchange prevailing between
      the Business Day before the day on which the judgment is given or an order
      of enforcement is made, as the case may be (or such other date as a court
      shall determine), and the date of receipt of the amount due, the Company
      or the relevant Guarantor, as the case may be, will pay such additional
      (or, as the case may be, such lesser) amount, if any, as may be necessary
      so that the amount paid in the judgment currency when converted at the
      rate of exchange prevailing on the date of receipt will produce the amount
      in the Base Currency originally due.

            (ii) the event of the winding-up of the Company or any Guarantor at
      any time while any amount or damages owing under the Securities, the
      Guarantee and this Indenture, or any judgment or order rendered in respect
      thereof, shall remain outstanding, the Company or the 

<PAGE>
                                      -43-


      relevant Guarantor, as the case may be, shall indemnify and hold the
      Holders and the Trustee harmless against any deficiency arising or
      resulting from any variation in rates of exchange between (1) the date as
      of which the U.S. Dollar Equivalent of the amount due or contingently due
      under the Securities, the Guarantees and this Indenture (other than under
      this Subsection (b)(ii)) is calculated for the purposes of such winding-up
      and (2) the final date for the filing of proofs of claim in such
      winding-up. For the purpose of this Subsection (b)(ii), the final date for
      the filing of proofs of claim in the winding-up of the Company or the
      relevant Guarantor, as the case may be, shall be the date fixed by the
      liquidator or otherwise in accordance with the relevant provisions of
      applicable law as being the latest practicable date as at which
      liabilities of the Company or the relevant Guarantor, as the case may be,
      may be ascertained for such winding-up prior to payment by the liquidator
      or otherwise in respect thereto. 

            (iii) The obligations contained in Subsections (a), (b)(i)(B) and
      (b)(ii) of this Section 1.20 shall constitute separate and independent
      obligations from the other Indenture Obligations of the Company and the
      Guarantors, shall give rise to separate and independent causes of action
      against the Company and each Guarantor, shall apply irrespective of any
      waiver or extension granted by any Holder or the Trustee or either of them
      from time to time and shall continue in full force and effect
      notwithstanding any judgment or order or the filing of any proof of claim
      in the winding-up of the Company or any Guarantor for a liquidated sum in
      respect of amounts due hereunder (other than under Subsection (b)(ii)
      above) or under any such judgment or order. Any such deficiency as
      aforesaid shall be deemed to constitute a loss suffered by the Holders or
      the Trustee, as the case may be, and no proof or evidence of any actual
      loss shall be required by the Company or the relevant Guarantor or the
      liquidator or otherwise or any of them. In the case of Subsection (b)(ii)
      above, the amount of such deficiency shall not be deemed to be reduced by
      any variation in rates of exchange occurring between the said final date
      and the date of any liquidating distribution.

            (iv) The term "rate(s) of exchange" shall mean the rate of exchange
      quoted by Reuters at 10:00 a.m. (New York time) for spot purchases of the
      Base Currency with the judgment currency other than the Base Currency
      referred to 

<PAGE>
                                      -44-


      in Subsections (b)(i) and (b)(ii) above and includes any premiums and
      costs of exchange payable.

            (c) In the event that on any payment date in respect of the
Securities or any Guarantee, any restrictions or prohibition of access to the
Brazilian foreign exchange market exists, the Company and each Guarantor agree
to pay all amounts payable under the Securities and the Guarantees in the
currency of the Securities by means of any legal procedure existing in Brazil
(except commencing legal proceedings against the Central Bank of Brazil), on any
due date for payment under the Securities, for the purchase of the currency of
such Securities. All costs and taxes payable in connection with the procedures
referred to in this Section 1.20 shall be borne by the Company and the
Guarantors.

            (b) Optional Redemption upon Significant Equity Offering. On or
prior to June 6, 2000, the Company may, at its option, use the net proceeds of
one or more Significant Equity Offerings yielding gross cash proceeds of not
less than US$35,000,000 (or, to the extent non-U.S. dollar denominated, the U.S.
Dollar Equivalent thereof) to redeem up to an aggregate of 35% of the principal
amount of the Securities originally issued from Holders on a pro rata basis (or
as nearly pro rata as practicable), at a redemption price of 113 1/2% of the
principal amount thereof, plus accrued and unpaid interest (together with any
Additional Amounts and Additional Interest payable hereon), if any, to the date
of redemption; provided 

<PAGE>
                                      -51-


that not less than US$81,250,000 in aggregate principal amount of Securities
would remain outstanding immediately after such redemption. To effect the
foregoing redemption, the Company must mail a notice of redemption complying
with Section 11.05 of the Indenture not later than 60 days after the
consummation of the Significant Equity Offering that resulted in the requisite
gross proceeds. As used above, "Significant Equity Offering" means a public
offering of Capital Stock (other than Disqualified Capital Stock) of the Company
(or American Depositary Receipts or Global Depositary Receipts representing such
Capital Stock) either (x) in the United States pursuant to an offering
registered under the Securities Act or (y) in Brazil pursuant to an offering
registered with the Comissao de Valores Mobiliarios ("CVM") and listed on the
Sao Paulo Stock Exchange or Rio de Janeiro Stock Exchange and/or (z) in the
United Kingdom pursuant to an offering that results in such Capital Stock (or
Global Depositary Receipts representing such Capital Stock) being listed on the
London Stock Exchange or the Luxembourg Stock Exchange.

            (c) Sinking Fund. The Company will not be required to make any
mandatory sinking fund payments in respect of the Securities.

            (d) Interest Payments. In the case of any redemption of Series A
Securities, interest installments whose Stated Maturity is on or prior to the
Redemption Date (together with any Additional Amounts payable thereon) will be
payable to the Holders of such Securities, or one or more Predecessor
Securities, of record at the close of business on the relevant Record Date
referred to on the face hereof. Securities (or portions thereof) for whose
redemption and payment provision is made in accordance with the Indenture shall
cease to bear interest from and after the Redemption Date.

            (e) Partial Redemption. In the event of redemption of this Series A
Security in part only, a new Series A Security or Securities for the unredeemed
portion hereof shall be issued in the name of the Holder hereof upon the
cancellation hereof.

            4. Tax Redemption. The Securities may be redeemed at the option of
the Company, in whole but not in part, at any time prior to maturity if (A)
there is any change in or amendment to the Treaty to Avoid Double Taxation
entered into between the Federative Republic of Brazil and Japan, approved by
Legislative Decree No. 43 dated November 23, 1967, and enacted in Brazil by
Decree No. 61,899 dated December 14, 1967, as amended by Decree No. 81,194 dated
January 9, 1978, which has

<PAGE>
                                      -52-


the effect of increasing the rate of tax applicable under such treaty to a rate
exceeding 15.0% of interest payable; or (B) (i) as the result of any change in
or amendment to the laws or regulations of the Federative Republic of Brazil or
Japan, the Company has or will become obligated to pay, or (ii) any act is taken
by a taxing authority of the Federative Republic of Brazil or Japan after the
date of issuance of the Securities (whether or not such action is taken with
respect to the Company or any Affiliate thereof) that results in a substantial
probability that the Company will be required to pay, Additional Amounts
(excluding interest and penalties) in excess of the Additional Amounts that the
Company would be obligated to pay if Brazilian Taxes (excluding interest and
penalties) were payable with respect to such payments of interest at a rate of
15.0% and such obligation cannot be avoided by the Company, taking reasonable
measures available to it, upon not more than 60 nor less than 30 days' notice to
the holders of such Securities (with copies to the Trustee and each Paying
Agent) at a redemption price of 100% of the principal amount thereof, plus
accrued and unpaid interest to the redemption date plus any such Additional
Amounts payable with respect to such redemption price and interest as provided
under Section 10.08 of the Indenture. Prior to the giving of notice of
redemption of the Securities as described herein and as a condition to any such
redemption, the Company will deliver to the Trustee an Officers' Certificate
(together with a copy of the written opinion of counsel to the effect that the
applicable rate has so increased, or the Company has or will become so
obligated, or that an action taken by a taxing authority of Brazil has resulted
in a substantial probability that the Company will become so obligated to pay
Additional Amounts as a result of such change, amendment, interpretation or
action), stating that the Company is entitled to effect such redemption and
setting forth in reasonable detail a statement of facts relating thereto. No
notice of redemption shall be given earlier than 60 days prior to the earliest
date on which the Company would be obligated or there is a substantial
probability that the Company would be obligated to pay such Additional Amounts
were a payment in respect of the Securities then due and, at the time such
notice of redemption is given, such obligation to pay, or such substantial
probability that the Company will be required to pay, such Additional Amounts
remains in effect.

            5. Offers to Purchase. Section 10.15 of the Indenture provides that
following any Asset Sale, and subject to further limitations contained therein,
the Company shall make an offer to purchase Securities in accordance with the
procedures set forth in the Indenture. In addition, the Company is 

<PAGE>
                                      -53-


required to make an offer to repurchase this Security at a purchase price of
101% of the principal amount hereof upon the occurrence of a Change of Control
in the manner set forth in Section 10.16.

            6. Defaults and Remedies. Events of Default under the Indenture
include, among others: (a) default in the payment of the principal of, or
premium, if any, on the Securities when due; (b) default in the payment of
interest on the Securities when it becomes due and payable and the continuance
of such default for a period of 30 days or more; provided, however, that a
failure to pay interest (but not Additional Amounts or Additional Interest) on
the Notes in a timely manner through June 6, 2000 will constitute an immediate
Event of Default, with no grace or cure period; (c) default in the performance,
or breach, of certain covenants in the Indenture, this Security or any
Guarantees, and continuance of such default or breach for a period of 45 days or
more after written notice; (d) failure by the Company or any Restricted
Subsidiary to perform any provision of one or more classes or issues of other
Indebtedness in an aggregate principal amount of US$5,000,000 (or, to the extent
non-U.S. dollar denominated, the U.S. Dollar Equivalent thereof) or more, and,
in the case of any such default other than a failure to pay, following any
applicable period of grace, principal on such Indebtedness when due, such
failure results in the acceleration of the maturity of such Indebtedness; (e)
one or more final and non-appealable judgments, orders or decrees for the
payment of money in the amount of US$5,000,000 (or, to the extent non-U.S.
dollar denominated, the U.S. Dollar Equivalent thereof) or more; (f) seizure,
compulsory acquisition, expropriation or nationalization of substantially all of
the assets of the Company and the Restricted Subsidiaries, taken as a whole; (g)
any Guarantee ceases to be in full force and effect or is declared null and void
or any Guarantor denies that it has any further liability under, or disaffirms
its obligations under, any Guarantee or gives notice to that effect (other than
by reason of the termination of the Indenture or the release of any Guarantee in
accordance with the Indenture); (h) the Company asserts or admits in writing
that the Escrow Agreement is unenforceable or is not in full force and effect;
and (i) certain events of bankruptcy, dissolution, insolvency, reorganization or
administration with respect to the Company or any Material Restricted Subsidiary
shall have occurred.

            Subject to certain limitations in the Indenture, if an Event of
Default (other than an Event of Default as specified in clause (i) of the
previous paragraph with respect to 

<PAGE>
                                      -54-


the Company or (f) of the previous paragraph) occurs and is continuing, then the
Trustee or the Holders of not less than 25% in aggregate principal amount of the
Outstanding Securities may, and the Trustee upon the request of the Holders of
not less than 25% in aggregate principal amount of the Outstanding Securities
shall, declare all principal or premium, if any, on and any accrued and unpaid
interest on all Outstanding Securities (and any Additional Amounts payable in
respect thereof) to be immediately due and payable. If an Event of Default
specified in clause (h) of the previous paragraph with respect to the Company or
clause (f) of the previous paragraph occurs, then the principal amount of, and
any accrued and unpaid interest on, all Outstanding Securities (and any
Additional Amounts payable in respect thereof) shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder. Except in the case of a default of a specific amount
of premium due, the amount of any premium shall be determined by interpolation
between (a) the premium payable on the next succeeding date on which either
Holders or the Company may optionally redeem Securities or on which the
Securities mature, as applicable (a "Payment Date"), and (b) the immediately
preceding Payment Date or, if there is no immediately preceding Payment Date,
0%.

            7. Defeasance. The Indenture contains provisions (which provisions
apply to this Series A Security) for defeasance at any time of (a) the entire
indebtedness of the Company and any Guarantors on this Series A Security and (b)
certain restrictive covenants and related Defaults and Events of Default, in
each case upon compliance by the Company with certain conditions set forth
therein.

            8. Amendments and Waivers. The Company, the Guarantors, if any, and
the Trustee (if a party thereto) may, without the consent of the Holders of any
Outstanding Securities, amend, waive or supplement the Indenture, the Securities
or the Guarantees for certain specified purposes, including, among other things,
curing ambiguities, defects or inconsistencies, maintaining the qualification of
the Indenture under the Trust Indenture Act of 1939, as amended, and making any
change that does not adversely affect the rights of any Holder. Other amendments
and modifications of the Indenture, the Securities or the Guarantees may be made
by the Company, the Guarantors, if any, and the Trustee with the consent of the
Holders of not less than a majority of the aggregate principal amount of the
Outstanding Securities, subject to certain exceptions requiring the consent of
the Holders of the particular Securities to be affected. Any such consent or
waiver by or on behalf of the 

<PAGE>
                                      -55-


Holder of this Series A Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Series A Security and of any Series A
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof whether or not notation of such consent or waiver is made upon
this Series A Security.

            9. Denominations, Transfer and Exchange. The Series A Securities are
issuable only in registered form without coupons in denominations of US$1,000
and any integral multiple thereof. As provided in the Indenture and subject to
certain limitations therein set forth, the Series A Securities are exchangeable
for a like aggregate principal amount of Series A Securities of a different
authorized denomination, as requested by the Holder surrendering the same.

            If this Series A Security is in certificated form, then as provided
in the Indenture and subject to certain limitations therein set forth, the
transfer of this Series A Security is registrable on the Security Register of
the Company, upon surrender of this Series A Security for registration of
transfer at the office or agency of the Company maintained for such purpose in
The City of New York or at such other office or agency of the Company as may be
maintained for such purpose, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Series A Securities, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

            If this Series A Security is a Restricted Security in certificated
form, then as provided in the Indenture and subject to certain limitations
therein set forth, the Holder, provided it is a Qualified Institutional Buyer,
may exchange this Series A Security for a book-entry security by instructing the
Trustee to arrange for such Series A Security to be represented by a beneficial
interest in a Global Security in accordance with the customary procedures of the
Depository.

            If this Series A Security is a Global Security, it is exchangeable
for Series A Securities in certificated form if (i) the Depository notifies the
Company that it is unwilling or unable to continue as depository or the
Depository ceases to be a "clearing agency" registered under the Exchange Act
and, in each case, a successor Depository is not appointed by the Company within
90 days of such notice or such cessation, as the 

<PAGE>
                                      -56-


case may be, or (ii) there shall have occurred and be continuing an Event of
Default with respect to any Securities represented by the Global Security and
Holders who hold more than 25% in aggregate principal amount of the Securities
at the time outstanding represented by the Global Security advise the Trustee
through the Depository in writing that the continuation of a book-entry system
through the Depository (or a successor thereto) with respect to the Global
Security is no longer required and the Security Registrar has received a request
from the Depository to issue certificated Securities. In addition, in accordance
with the provisions of the Indenture and subject to certain limitations therein
set forth, a beneficial owner of a beneficial interest in a Global Security may
request a Series A Security in certificated form, in exchange in whole or in
part, as the case may be, for such beneficial owner's interest in the Global
Security. In any such instance, an owner of a beneficial interest in a Global
Security will be entitled to physical delivery in certificated form of Series A
Securities in authorized denominations equal in principal amount to such
beneficial interest and to have such Series A Securities registered in its name.

            No service charge shall be made for any registration of transfer or
exchange or redemption of Series A Securities, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

            10. Certain Information Obligations. At any time when the Company is
not subject to Section 13 or 15(d) of the Securities Exchange Act of 1934, upon
the request of a Holder of a Series A Security, the Company will promptly
furnish or cause to be furnished such information as is specified pursuant to
Rule 144A(d)(4) under the Securities Act (or any successor provision thereto) to
such Holder or to a prospective purchaser of such Series A Security designated
by such Holder, as the case may be, in order to permit compliance by such Holder
with Rule 144A under the Securities Act. In addition, the Company is required to
furnish to the Trustee and to the Holder of this Security certain quarterly,
annual and other financial statements and other information as set forth in
Section 10.09 of the Indenture.

            11. Persons Deemed Owners. Prior to and at the time of due
presentment of this Series A Security for registration of transfer, the Company,
the Trustee and any agent of the Company or the Trustee may treat the person in
whose name this Series A Security is registered as the owner hereof for all
pur-

<PAGE>
                                      -57-


poses, whether or not this Series A Security shall be overdue, and neither the
Company, the Trustee nor any agent shall be affected by notice to the contrary.

            12. GOVERNING LAW. THE INDENTURE, THIS SECURITY AND THE GUARANTEES
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
NEW YORK WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAW, EXCEPT THAT
MATTERS RELATING TO THE AUTHORIZATION BY THE COMPANY OR ANY GUARANTORS OF THE
INDENTURE, THIS SECURITY AND THE GUARANTEES SHALL BE GOVERNED BY THE APPLICABLE
LAWS OF THE FEDERATIVE REPUBLIC OF BRAZIL OR OTHER JURISDICTION OF ITS
ORGANIZATION. THE TRUSTEE, THE COMPANY, ANY GUARANTOR, ANY OTHER OBLIGOR IN
RESPECT OF THE SECURITIES AND THE HOLDERS AGREE TO SUBMIT TO THE NON-EXCLUSIVE
JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT LOCATED IN THE BOROUGH
OF MANHATTAN IN THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF
OR RELATING TO THE INDENTURE, THIS SECURITY OR ANY GUARANTEES.

            13. Paying Agents and Registrar. Initially, The Chase Manhattan
Bank, a banking corporation (the "Trustee"), will act as co-Paying Agent and
Registrar. Initially, Chase Trust Company will act as Principal Paying Agent.
The Company may change any Paying Agent, Registrar or co-Registrar. Upon such
change, the Company shall give written notice thereof to the Trustee and the
Holders. Neither the Company nor any of its Affiliates may act as Registrar or
co-Registrar. The Company may, subject to Section 3.08 and Section 10.03 of the
Indenture, act as Paying Agent.

            14. Additional Amounts. The Company will pay to the Holders of
Securities such Additional Amounts as may become payable under Section 10.08 of
the Indenture.

            15. Conversion of Currency. U.S. dollars are the sole currency of
account and payment for all sums payable by the Company and the Guarantors under
or in connection with the Securities, the Guarantees or the Indenture, including
damages. The Company and each Guarantor have agreed that the provisions of
Section 1.20 of the Indenture shall apply to conversion of currency in the case
of the Securities, the Guarantees and the Indenture. Among other things, Section
1.20 specifies that if there is a change in the rate of exchange prevailing
between the Business Day before the day on which a judgment is given or an order
of enforcement is made, as the case may be (or such other date as a court shall
determine), and the date of receipt of the amount due, the Company or the
relevant Guarantor, as the case may be, will pay such additional (or, as the
case may 

<PAGE>
                                      -58-


be, such lesser) amount, if any, as may be necessary so that the amount paid in
the judgment currency when converted at the rate of exchange prevailing on the
date of receipt will produce the amount in the Base Currency originally due. In
the event that on any payment date in respect of the Securities or any
Guarantee, any restrictions or prohibition of access to the Brazilian foreign
exchange market exists, the Company and each Guarantor agrees to pay all amounts
payable under the Securities and the Guarantees in the currency of the
Securities by means of any legal procedure existing in Brazil (except commencing
legal proceedings against the Central Bank of Brazil), on any due date for
payment under the Securities, for the purchase of the currency of such
Securities. All costs and taxes payable in connection with the procedures
referred to in this paragraph shall be borne by the Company and the Guarantors.

            16. Agent for Service; Submission to Jurisdiction, Waiver of
Immunities. The Company and each Guarantor have appointed CT Corporation System,
currently located at 1633 Broadway, New York, New York 10019, as its authorized
agent upon which process may be served in any suit, or proceeding with respect
to, arising out of, or relating to, this Security, the Indenture or any
Guarantee, that may be instituted in any Federal or state court in the State of
New York, The City of New York, the Borough of Manhattan, or brought under
Federal or state securities laws and have agreed that there shall, at all times,
be at least one agent for service of process for the Company and the Guarantors
appointed and acting in accordance with the provisions of Section 1.19 of the
Indenture relating to agent for service of process. To the extent that the
Company or any Guarantor has or hereafter may acquire any immunity from
jurisdiction of any court or from any legal process (whether through service of
notice, attachment prior to judgment, attachment in aid of execution, execution
or otherwise) with respect to itself or its property, the Company and each
Guarantor have irrevocably waived such immunity in respect of its obligations
under the Indenture, this Security and the Guarantees, to the extent permitted
by law.

            17. Registration Rights. Pursuant to the Notes Registration Rights
Agreement among the Company and the Holders of the Series A Securities, the
Company and any Guarantor will be obligated to consummate an exchange offer
pursuant to which the Holder of this Security shall have the right to exchange
this Security together with the Guarantees hereof whether or not endorsed hereon
for 13 1/2% Senior Notes due 2005, Series B, of the Company (herein called the
"Series B Securities"), which have been registered under the Securities Act, in
like princi-

<PAGE>
                                      -59-


pal amount and having identical terms as the Series A Securities, except that
such Series B Securities shall not bear the Private Placement Legend and this
paragraph relating to registration rights shall not be included therein. The
Holders of Series A Securities shall be entitled to receive certain Additional
Interest in the event such exchange offer is not consummated and upon certain
other conditions, all pursuant to and in accordance with the terms of the Notes
Registration Rights Agreement. Whenever in the Indenture or in this Security
there is mentioned, in any context, the payment of amounts based upon the
payment of principal, premium, if any, interest or of any other amount payable
under or with respect to any Security, such mention shall be deemed to include
mention of the payment of Additional Amounts and Additional Interest to the
extent that, in such context, Additional Amounts and Additional Interest are,
were or would be payable in respect thereof. The Series A Securities and the
Series B Securities are together referred to herein as the "Securities."

            (b) The form of the reverse of the Series B Securities shall be
substantially as follows:

            1. Indenture. This Security is one of a duly authorized issue of
Securities of the Company designated as its 13 1/2% Senior Notes due 2005,
Series B (herein called the "Series B Securities"), limited (except as otherwise
provided in the Indenture referred to below) in aggregate principal amount to
US$125,000,000, which may be issued under an indenture (herein called the
"Indenture") dated as of June 1, 1997, between the Company and The Chase
Manhattan Bank, as trustee (herein called the "Trustee," which term includes any
successor Trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitation of rights, du-

<PAGE>
                                      -63-


ties, obligations, covenants and immunities thereunder of the Company, the
Trustee, the Guarantors and the Holders of the Securities, and of the terms upon
which the Securities are, and are to be, authenticated and delivered.

            All capitalized terms used in this Series B Security which are
defined in the Indenture and not otherwise defined herein shall have the
meanings assigned to them in the Indenture.

            No reference herein to the Indenture and no provision of this Series
B Security or of the Indenture shall alter or impair the obligation of the
Company or any Guarantor, which is absolute and unconditional, to pay the
principal of, premium, if any, and interest on this Security at the times,
place, and rate, and in the coin or currency, herein prescribed.

            The Series B Securities were issued pursuant to an exchange offer
pursuant to which 13 1/2% Senior Notes due 2005, Series A of the Company (herein
called the "Series A Securities"), in like principal amount and having
substantially identical terms as the Series B Securities (except that the Series
A Securities were subject to certain restrictions on transfer thereof), were
exchanged for the Series B Securities. The Series A Securities and the Series B
Securities are together referred to herein as the "Securities."

            2. Guarantees; Collateral. The Indenture provides that each Material
Restricted Subsidiary shall become a Guarantor of this Security. The Holder of
this Security may obtain the endorsement of any such Guarantee upon this
Security by presenting this Security to the Trustee. The Indenture further
provides this Security shall have the full benefit of and every right and
privilege relating to any such Guarantee notwithstanding that such Guarantee is
not endorsed hereon. The Holder of this Security will be entitled to the
benefits of the Escrow Agreement between the Company and the Trustee dated as of
June 1, 1997, including the security interest in the Collateral granted to the
trustee for the benefit of the Holders of Securities pursuant thereto until such
Collateral is released pursuant to the terms of the Escrow Agreement.

            3. Redemption.

            (a) Optional Redemption. The Securities are subject to redemption,
in whole or in part at any time, on or after June 6, 2001 at the option of the
Company, upon not less than 30 nor more than 60 days prior notice in principal
amounts of 

<PAGE>
                                      -64-


US$1,000 or any integral multiple of US$1,000, at the redemption prices
(expressed as percentages of principal amount) set forth below plus accrued and
unpaid interest (together with any Additional Amounts payable hereon) to the
redemption date, if redeemed during the 12 month period beginning June 6 of the
years indicated below:

            Year                                 Redemption Price
            ----                                 ----------------
            2001                                      106.75%
            2002                                      104.50%
            2003                                      102.25%
            2004 and thereafter                       100.00%

            (b) Optional Redemption upon Significant Equity Offering. On or
prior to June 6, 2000, the Company may, at its option, use the net proceeds of
one or more Significant Equity Offerings yielding gross cash proceeds of not
less than US$35,000,000 (or, to the extent non-U.S. dollar denominated, the U.S.
Dollar Equivalent thereof)to redeem up to an aggregate of 35% of the principal
amount of the Securities originally issued from Holders on a pro rata basis (or
as nearly pro rata as practicable), at a redemption price of 113 1/2% of the
principal amount thereof, plus accrued and unpaid interest (together with any
Additional Amounts payable hereon), if any, to the date of redemption; provided
that not less than US$81,250,000 in aggregate principal amount of Securities
would remain outstanding immediately after such redemption. To effect the
foregoing redemption, the Company must mail a notice of redemption complying
with Section 11.05 of the Indenture not later than 60 days after the
consummation of the Significant Equity Offering that resulted in the requisite
gross proceeds. As used above, "Significant Equity Offering" means either a
public offering of Capital Stock (other than Disqualified Capital Stock) of the
Company (or American Depositary Receipts or Global Depositary Receipts
representing such Capital Stock) either (x) in the United States pursuant to an
offering registered under the Securities Act or (y) in Brazil pursuant to an
offering registered with the Comissao de Valores Mobiliarios ("CVM") and listed
on the Sao Paulo Stock Exchange or Rio de Janeiro Stock Exchange and/or (z) in
the United Kingdom pursuant to an offering that results in such Capital Stock
(or Global Depositary Receipts representing such Capital Stock) being listed on
the London Stock Exchange or the Luxembourg Stock Exchange.

                                      -65-


            (c) Sinking Fund. The Company will not be required to make any
mandatory sinking fund payments in respect of the Securities.

            (d) Interest Payments. In the case of any redemption of Series B
Securities, interest installments whose Stated Maturity is on or prior to the
Redemption Date (together with any Additional Amounts payable thereon) will be
payable to the Holders of such Securities, or one or more Predecessor
Securities, of record at the close of business on the relevant Record Date
referred to on the face hereof. Securities (or portions thereof) for whose
redemption and payment provision is made in accordance with the Indenture shall
cease to bear interest from and after the Redemption Date.

            (e) Partial Redemption. In the event of redemption of this Series B
Security in part only, a new Series B Security or Securities for the unredeemed
portion hereof shall be issued in the name of the Holder hereof upon the
cancellation hereof.

            4. Tax Redemption. The Securities may be redeemed at the option of
the Company, in whole but not in part, at any time prior to maturity if (A)
there is any change in or amendment to the Treaty to Avoid Double Taxation
entered into between the Federative Republic of Brazil and Japan, approved by
Legislative Decree No. 43 dated November 23, 1967, and enacted in Brazil by
Decree No. 61,899 dated December 14, 1967, as amended by Decree No. 81,194 dated
January 9, 1978, which has the effect of increasing the rate of tax applicable
under such treaty to a rate exceeding 15.0% of interest payable; or (B) (i) as
the result of any change in or amendment to the laws or regulations of the
Federative Republic of Brazil or Japan, the Company has or will become obligated
to pay, or (ii) any act is taken by a taxing authority of the Federative
Republic of Brazil or Japan after the date of issuance of the Securities
(whether or not such action is taken with respect to the Company or any
Affiliate thereof) that results in a substantial probability that the Company
will be required to pay, Additional Amounts (excluding interest and penalties)
in excess of the Additional Amounts that the Company would be obligated to pay
if Brazilian Taxes (excluding interest and penalties) were payable with respect
to such payments of interest at a rate of 15.0% and such obligation cannot be
avoided by the Company, taking reasonable measures available to it, upon not
more than 60 nor less than 30 days' notice to the holders of such Securities
(with copies to the Trustee and each Paying Agent) at a redemption price of 100%
of the principal amount thereof, plus accrued and unpaid interest to the
redemption date plus any 

<PAGE>
                                      -66-


such additional Amounts payable with respect to such redemption price and
interest as provided under Section 10.08 of the Indenture. Prior to the giving
of notice of redemption of the Securities as described herein and as a condition
to any such redemption, the Company will deliver to the Trustee an Officers'
Certificate (together with a copy of the written opinion of counsel to the
effect that the applicable rate has so increased, or the Company has or will
become so obligated, or that an action taken by a taxing authority of Brazil has
resulted in a substantial probability that the Company will become so obligated
to pay Additional Amounts as a result of such change, amendment, interpretation
or action), stating that the Company is entitled to effect such redemption and
setting forth in reasonable detail a statement of facts relating thereto. No
notice of redemption shall be given earlier than 60 days prior to the earliest
date on which the Company would be obligated or there is a substantial
probability that the Company would be obligated to pay such Additional Amounts
were a payment in respect of the Securities then due and, at the time such
notice of redemption is given, such obligation to pay, or such substantial
probability that the Company will be required to pay, such Additional Amounts
remains in effect.

            5. Offers to Purchase. Section 10.15 of the Indenture provides that
following any Asset Sale, and subject to further limitations contained therein,
the Company shall make an offer to purchase Securities in accordance with the
procedures set forth in the Indenture. In addition, the Company is required to
make an offer to repurchase this Security at a purchase price of 101% of the
principal amount hereof upon the occurrence of a Change of Control in the manner
set forth in Section 10.16.

            6. Defaults and Remedies. Events of Default under the Indenture
include, among others: (a) default in the payment of the principal of, or
premium, if any, on the Securities when due; (b) default in the payment of
interest on the Securities when it becomes due and payable and the continuance
of such default for a period of 30 days or more; provided, however, that a
failure to pay interest (but not Additional Amounts or Additional Interest) on
the Notes in a timely manner through June 6, 2000 will constitute an immediate
Event of Default, with no grace or cure period; (c) default in the performance,
or breach, of certain covenants in the Indenture, this Security or any
Guarantees, and continuance of such default or breach for a period of 45 days or
more after written notice; (d) failure by the Company or any Restricted
Subsidiary to perform any provision of one or more classes or issues of 

<PAGE>
                                      -67-


other Indebtedness in an aggregate principal amount of US$5,000,000 (or, to the
extent non-U.S. dollar denominated, the U.S. Dollar Equivalent thereof) or more,
and, in the case of any such default other than a failure to pay, following any
applicable period of grace, principal on such Indebtedness when due, such
failure results in the acceleration of the maturity of such Indebtedness; (e)
one or more final and non-appealable judgments, orders or decrees for the
payment of money in the amount of US$5,000,000 (or, to the extent non-U.S.
dollar denominated, the U.S. Dollar Equivalent thereof) or more; (f) seizure,
compulsory acquisition, expropriation or nationalization of substantially all of
the assets of the Company and the Restricted Subsidiaries, taken as a whole; (g)
any Guarantee ceases to be in full force and effect or is declared null and void
or any Guarantor denies that it has any further liability under, or disaffirms
its obligations under, any Guarantee or gives notice to that effect (other than
by reason of the termination of the Indenture or the release of any Guarantee in
accordance with the Indenture); (h) the Company asserts or admits in writing
that the Escrow Agreement is unenforceable or is not in full force and effect;
and (i) certain events of bankruptcy, dissolution, insolvency, reorganization or
administration with respect to the Company or any Material Restricted Subsidiary
shall have occurred.

            Subject to certain limitations in the Indenture, if an Event of
Default (other than an Event of Default as specified in clause (i) of the
previous paragraph with respect to the Company or (f) of the previous paragraph)
occurs and is continuing, then the Trustee or the Holders of not less than 25%
in aggregate principal amount of the Outstanding Securities may, and the Trustee
upon the request of the Holders of not less than 25% in aggregate principal
amount of the Outstanding Securities shall, declare all principal or premium, if
any, on and any accrued and unpaid interest on all Outstanding Securities (and
any Additional Amounts payable in respect thereof) to be immediately due and
payable. If an Event of Default specified in clause (h) of the previous
paragraph with respect to the Company or clause (f) of the previous paragraph
occurs, then the principal amount of, and any accrued and unpaid interest on,
all Outstanding Securities (and any Additional Amounts payable in respect
thereof) shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder. Except in the
case of a default of a specific amount of premium due, the amount of any premium
shall be determined by interpolation between (a) the premium payable on the next
succeeding date on which either Holders or the Company may optionally redeem
Securities or on

<PAGE>
                                      -68-


which the Securities mature, as applicable (a "Payment Date"), and (b) the
immediately preceding Payment Date or, if there is no immediately preceding
Payment Date, 0%.

            7. Defeasance. The Indenture contains provisions (which provisions
apply to this Series A Security) for defeasance at any time of (a) the entire
indebtedness of the Company and any Guarantors on this Series A Security and (b)
certain restrictive covenants and related Defaults and Events of Default, in
each case upon compliance by the Company with certain conditions set forth
therein.

            8. Amendments and Waivers. The Company, the Guarantors, if any, and
the Trustee (if a party thereto) may, without the consent of the Holders of any
Outstanding Securities, amend, waive or supplement the Indenture, the Securities
or the Guarantees for certain specified purposes, including, among other things,
curing ambiguities, defects or inconsistencies, maintaining the qualification of
the Indenture under the Trust Indenture Act of 1939, as amended, and making any
change that does not adversely affect the rights of any Holder. Other amendments
and modifications of the Indenture, the Securities or the Guarantees may be made
by the Company, the Guarantors, if any, and the Trustee with the consent of the
Holders of not less than a majority of the aggregate principal amount of the
Outstanding Securities, subject to certain exceptions requiring the consent of
the Holders of the particular Securities to be affected. Any such consent or
waiver by or on behalf of the Holder of this Series B Security shall be
conclusive and binding upon such Holder and upon all future Holders of this
Series B Security and of any Series B Security issued upon the registration of
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent or waiver is made upon this Series B Security.

            9. Denominations, Transfer and Exchange. The Series B Securities are
issuable only in registered form without coupons in denominations of US$1,000
and any integral multiple thereof. As provided in the Indenture and subject to
certain limitations therein set forth, the Series B Securities are exchangeable
for a like aggregate principal amount of Series B Securities of a different
authorized denomination, as requested by the Holder surrendering the same.

            If this Series B Security is in certificated form, then as provided
in the Indenture and subject to certain limitations therein set forth, the
transfer of this Series B Security is registrable on the Security Register of
the Company, 

<PAGE>
                                      -69-


upon surrender of this Series B Security for registration of transfer at the
office or agency of the Company maintained for such purpose in The City of New
York or at such other office or agency of the Company as may be maintained for
such purpose, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Series B Securities, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

            If this Series B Security is a Global Security, it is exchangeable
for Series B Securities in certificated form if (i) the Depository notifies the
Company that it is unwilling or unable to continue as depository or the
Depository ceases to be a "clearing agency" registered under the Exchange Act
and, in each case, a successor Depository is not appointed by the Company within
90 days of such notice or such cessation, as the case may be, or (ii) there
shall have occurred and be continuing an Event of Default with respect to any
Securities represented by this Global Security and Holders who hold more than
25% in aggregate principal amount of the Securities at the time outstanding
represented by this Global Security advise the Trustee through the Depository in
writing that the continuation of book-entry system through the Depository (or a
successor thereto) with respect to this Global Security is no longer required
and the Security Registrar has received a request from the Depository to issue
certificated Securities. In addition, in accordance with the provisions of the
Indenture and subject to certain limitations therein set forth, a beneficial
owner of a beneficial interest in a Global Security may request a Series B
Security in certificated form, in exchange in whole or in part, as the case may
be, for such beneficial owner's interest in the Global Security. In any such
instance, an owner of a beneficial interest in a Global Security will be
entitled to physical delivery in certificated form of Series B Securities in
authorized denominations equal in principal amount to such beneficial interest
and to have such Series B Securities registered in its name.

            No service charge shall be made for any registration of transfer or
exchange or redemption of Series B Securities, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.


<PAGE>
                                      -70-


            10. Certain Information Obligations. The Company is required to
furnish to the Trustee and to the Holder of this Security certain quarterly,
annual and other financial statements and other information as set forth in
Section 10.09 of the Indenture.

            11. Persons Deemed Owners. Prior to and at the time of due
presentment of this Series B Security for registration of transfer, the Company,
the Trustee and any agent of the Company or the Trustee may treat the person in
whose name this Series B Security is registered as the owner hereof for all
purposes, whether or not this Series B Security shall be overdue, and neither
the Company, the Trustee nor any agent shall be affected by notice to the
contrary.

            12. GOVERNING LAW. THE INDENTURE, THIS SECURITY AND THE GUARANTEES
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
NEW YORK WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAW, EXCEPT THAT
MATTERS RELATING TO THE AUTHORIZATION BY THE COMPANY OR ANY GUARANTORS OF THE
INDENTURE, THIS SECURITY AND THE GUARANTEES SHALL BE GOVERNED BY THE APPLICABLE
LAWS OF THE FEDERATIVE REPUBLIC OF BRAZIL OR OTHER JURISDICTION OF ITS
ORGANIZATION. THE TRUSTEE, THE COMPANY, ANY GUARANTOR, ANY OTHER OBLIGOR IN
RESPECT OF THE SECURITIES AND THE HOLDERS AGREE TO SUBMIT TO THE NON-EXCLUSIVE
JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT LOCATED IN THE BOROUGH
OF MANHATTAN IN THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF
OR RELATING TO THE INDENTURE, THIS SECURITY OR ANY GUARANTEES.

            13. Paying Agents and Registrar. Initially, The Chase Manhattan
Bank, a banking corporation (the "Trustee") will act as co-Paying Agent and
Registrar. Initially, Chase Trust Company will act as Principal Paying Agent.
The Company may change any Paying Agent, Registrar or co-Registrar. Upon such
change, the Company shall give written notice thereof to the Trustee and the
Holders. Neither the Company nor any of its Affiliates may act as Registrar or
co-Registrar. The Company may, subject to Section 3.08 and Section 10.03 of the
Indenture, act as Paying Agent.

            14. Additional Amounts. The Company will pay to the Holders of
Securities such Additional Amounts as may become payable under Section 10.08 of
the Indenture.

            15. Conversion of Currency. U.S. dollars are the sole currency of
account and payment for all sums payable by the Company and the Guarantors under
or in connection with the 

<PAGE>
                                      -71-


Securities, the Guarantees or the Indenture, including damages. The Company and
each Guarantor have agreed that the provisions of Section 1.20 of the Indenture
shall apply to conversion of currency in the case of the Securities, the
Guarantees and the Indenture. Among other things, Section 1.20 specifies that if
there is a change in the rate of exchange prevailing between the Business Day
before the day on which a judgment is given or an order of enforcement is made,
as the case may be (or such other date as a court shall determine), and the date
of receipt of the amount due, the Company or the relevant Guarantor, as the case
may be, will pay such additional (or, as the case may be, such lesser) amount,
if any, as may be necessary so that the amount paid in the judgment currency
when converted at the rate of exchange prevailing on the date of receipt will
produce the amount in the Base Currency originally due. In the event that on any
payment date in respect of the Securities or any Guarantee, any restrictions or
prohibition of access to the Brazilian foreign exchange market exists, the
Company and each agrees to pay all amounts payable under the Securities and the
Guarantees in the currency of the Securities by means of any legal procedure
existing in Brazil (except commencing legal proceedings against the Central Bank
of Brazil), on any due date for payment under the Securities, for the purchase
of the currency of such Securities. All costs and taxes payable in connection
with the procedures referred to in this paragraph shall be borne by the Company
and the Guarantors.

            16. Agent for Service; Submission to Jurisdiction; Waiver of
Immunities. The Company and each Guarantor have appointed CT Corporation System,
currently located at 1633 Broadway, New York, New York 10019, as its authorized
agent upon which process may be served in any suit, or proceeding with respect
to, arising out of, or relating to, this Security, the Indenture or any
Guarantee, that may be instituted in any Federal or state court in the State of
New York, The City of New York, the Borough of Manhattan, or brought under
Federal or state securities laws and have agreed that there shall, at all times,
be at least one agent for service of process for the Company and the Guarantors
appointed and acting in accordance with the provisions of Section 1.19 of the
Indenture relating to agent for service of process. To the extent that the
Company or any Guarantor has or hereafter may acquire any immunity from
jurisdiction of any court or from any legal process (whether through service of
notice, attachment prior to judgment, attachment in aid of execution, execution
or otherwise) with respect to itself or its property, the Company and each
Guarantor have irrevocably waived such immunity in respect of 

<PAGE>
                                      -72-


its obligations under the Indenture, this Security and the Guarantees, to the
extent permitted by law.

                               THE SECURITIES

            Section 3.01 Title and Terms.

            The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is limited to US$125,000,000 in
aggregate principal amount of Series A Securities and Series B Securities,
except for Securities authenticated and delivered upon registration of, transfer
of, or in exchange for, or in lieu of, other Securities pursuant to Section
3.03, 3.04, 3.05, 3.06, 9.06, 10.15, 10.16 or 11.08.

            The Series A Securities shall be known and designated as the "13
1/2% Senior Notes due 2005, Series A" of the Company. The Series B Securities
shall be known and designated as the "13 1/2% Senior Notes due 2005, Series B"
of the Company. The final Stated Maturity of the Series A Securities and the
Series B Securities shall be June 6, 2005, and the Series A Securities and
Series B Securities shall each bear interest at the rate of 13 1/2% per annum
from the Issue Date or from the most recent Interest Payment Date to which
interest has been paid, as the case may be, payable on December 6, 1997 and
semi-annually thereafter on June 6 and December 6, in each year, until the
principal thereof is paid or duly provided for. Subject to Article Thirteen,
interest on any overdue principal, interest (to the extent lawful) or premium,
if any, shall be payable on demand.

            Series B Securities may be issued only in exchange for a like
principal amount of Series A Securities pursuant to an Exchange Offer.

            Series A Securities offered and sold in reliance on Rule 144A shall
be issued initially in the form of a single permanent global security (the "U.S.
Global Security") and Series A Securities offered and sold in reliance on
Regulation S 

<PAGE>
                                      -78-


may be issued initially in the form of a permanent global security (the
"Offshore Global Security" and together with the U.S. Global Security, the
"Global Securities"), each substantially in the form set forth in Sections
2.02(a) and 2.03(a) hereof, deposited with the Trustee, as custodian of the
Depository, duly executed by the Company and authenticated by the Trustee as
hereinafter provided. The aggregate principal amount of any Global Security may
from time to time be increased or decreased by adjustments made on the records
of the Trustee, as custodian for the Depository or its nominee, as hereinafter
provided.

            Series A Securities which are offered and sold to Institutional
Accredited Investors which are not QIBs (excluding Non-U.S. Persons) shall be
issued in the form of permanent certificated Securities in registered form (the
"U.S. Physical Securities"). Securities issued pursuant to Section 3.14(b) in
exchange for interests in the U.S. Global Security shall be in the form of U.S.
Physical Securities. Series A Securities offered in reliance on Regulation S may
be issued initially in the form of permanent certificated Securities in
registered form and Securities issued in exchange for interests in the Offshore
Global Security pursuant to Section 3.14(b) shall be in the form of permanent
certificated Securities in registered form (together, the "Offshore Physical
Securities" and together with the U.S. Physical Securities, the "Physical
Securities").

            Physical Securities shall be in substantially the form set forth in
Sections 2.02(a) and 2.03(a) hereof.

            Subject to Section 3.13 hereof, the principal of, premium, if any,
and interest on Global Securities shall be payable at the office or agency of
the Company maintained for such purpose in the Borough of Manhattan in The City
of New York, or at such other office or agency of the Company as may be

Company interest may be paid by check mailed to the addresses of the persons
entitled thereto as such addresses shall appear on the Security Register.

            The Securities shall be redeemable only as provided in Article
Eleven.

            At the election of the Company, the entire Indebtedness on the
Securities or certain of the Company's obligations and covenants and certain
Events of Default thereunder may be defeased as provided in Article Four.

                                      -79-


            Section 3.02 Denominations.

            The Securities shall be issuable only in registered form without
coupons and only in denominations of US$1,000 and any integral multiple thereof.

            Section 3.03 Execution, Authentication, Delivery and Dating.

            The Securities shall be manually executed on behalf of the Company
by its Chairman of the Board, Vice-Chairman, its President or one of its Vice
Presidents.

            Securities bearing the manual signature of individuals who were at
any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices on the date of such Securities.

            At any time and from time to time upon or after the execution and
delivery of this Indenture, the Company may deliver Securities executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as
provided in this Indenture and not otherwise.

            Each Security shall be dated the date of its authentication.

            No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for in Section
2.04 hereof duly executed by the Trustee by manual signature of an authorized
representative, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder.

            In case the Company, pursuant to Article Eight, shall be
consolidated, amalgamated, merged with or into any other person or shall convey,
transfer or lease substantially all of its properties and assets to any person,
and the successor person resulting from such consolidation, amalgamation or
surviving such merger, or into which the Company shall have been merged, or the
person which shall have received a conveyance, 

<PAGE>
                                      -80-


transfer or lease as aforesaid, shall have executed an indenture supplemental
hereto with the Trustee pursuant to Article Eight, any of the Securities
authenticated or delivered prior to such consolidation, amalgamation, merger,
conveyance, transfer or lease may, from time to time, at the request of the
successor person, be exchanged for other Securities executed in the name of the
successor person with such changes in terminology and form as may be
appropriate, but otherwise in substance of like tenor as the Securities
surrendered for such exchange and of like principal amount; and the Trustee,
upon Company Order of the successor person, shall authenticate and deliver
replacement Securities as specified in such request for the purpose of such
exchange. If such Securities shall at any time be authenticated and delivered in
any new name of a successor person pursuant to this Section 3.03 in exchange or
substitution for or upon registration of transfer of any Securities, such
successor person, at the option of the Holders but without expense to them,
shall provide for the exchange of all Securities at the time Outstanding for
Securities authenticated and delivered in such new name.

            The Trustee may appoint an authenticating agent to authenticate
Securities on behalf of the Trustee if directed to do so by a Company Order.
Each reference in this Indenture to authentication by the Trustee includes
authentication by each such agent. An authenticating agent has the same rights
as any Security Registrar or Paying Agent to deal with the Company and its
Affiliates.

            If any of the Securities are to be issued in the form of one or more
Global Securities, then the Company shall execute and the Trustee shall
authenticate and deliver one or more Global Securities that (i) shall represent
and shall be in minimum denominations of US$1,000 or integral multiples thereof,
(ii) shall be registered in the name of the Depository for such Global Security
or Securities or the nominee of such Depository, (iii) shall be delivered by the
Trustee to such Depository or pursuant to such Depository's instructions and
(iv) shall bear the legend in substantially the form set forth in Section 2.06.

            If, pursuant to Section 10.18 hereof or otherwise, any Guarantor is
at any time subject to any Indenture Obligations, such Guarantor shall, upon
request of any Holder, endorse the Guarantee of such Guarantor on the Security
of such Holder or any replacement thereof; provided, however, that every
Guarantor shall be jointly and severally liable for Indenture Obligations and
each Security shall have the full bene-

<PAGE>
                                      -81-


fit of and every right and privilege relating to each Guarantee notwithstanding
that such Guarantee is not endorsed thereon.

            Section 3.04 Temporary Securities.

            Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities. Temporary Securities may be printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities.

            If temporary Securities are issued, the Company will cause
definitive Securities to be prepared without unreasonable delay but in no event
later than the date that the Registered Exchange Offer is consummated. After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company designated for such purpose
pursuant to Section 10.02, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a like
principal amount of definitive Securities of authorized denominations. Until so
exchanged the temporary Securities shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities.

            Section 3.05 Registration, Registration of Transfer and Exchange.

            The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 10.02 being herein sometimes
referred to as the "Security Register") in which, subject to such reasonable
regulations as the Security Registrar may prescribe, the Company shall provide
for the registration of Securities and of transfers of Securities. The Trustee
is hereby initially appointed "Security Registrar" for the purpose of
registering Securities and transfers of Securities as herein provided.

            Upon surrender for registration of transfer of any Security at the
office or agency of the Company designated pur-

<PAGE>
                                      -82-


suant to Section 10.02, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of any authorized denomination or
denominations, of a like aggregate principal amount.

            At the option of the Holder, Securities in certificated form may be
exchanged for other Securities of any authorized denomination or denominations,
of a like aggregate principal amount, upon surrender of the Securities to be
exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

            If a Series A Security is a U.S. Physical Security, then as provided
in this Indenture and subject to the limitations herein set forth, the Holder,
provided it is a Qualified Institutional Buyer, may exchange such Security for a
book-entry security by instructing the Trustee to arrange for such Series A
Security to be represented by a beneficial interest in a Global Security.

            All Securities issued upon any registration of transfer or exchange
of Securities including, without limitation, any exchange pursuant to an
Exchange Offer shall be the valid obligations of the Company, evidencing the
same Indebtedness, and entitled to the same benefits under this Indenture, as
the Securities surrendered upon such registration of transfer or exchange and no
such transfer or exchange shall constitute a repayment of any obligation nor
create any new obligations of the Company.

            Every Security presented or surrendered for registration of
transfer, or for exchange or redemption shall (if so required by the Company or
the Security Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security
Registrar, duly executed by the Holder thereof or his attorney duly authorized
in writing.

            Every Restricted Security shall be subject to the restrictions on
transfer provided in the legend required to be set forth on the face of each
Restricted Security pursuant to Section 2.05, Section 2.02(a) and the
restrictions set forth in this Section 3.05, and the Holder of each Restricted
Security, by such Holder's acceptance thereof, agrees to be bound by such
restrictions on transfer.


<PAGE>
                                      -83-


            The restrictions imposed by this Section 3.05 and Section 2.05 upon
the transferability of any particular Restricted Security shall cease and
terminate on (x) the later of June 6, 1999 or two years (or such shorter period
of time as permitted by Rule 144(k) under the Securities Act or any successor
provision thereunder) after the later of the Issue Date or the last date on
which the Company or any Affiliate of the Company was the owner of such
Restricted Security (or any predecessor of such Restricted Security) or (y) (if
earlier) if and when such Restricted Security has been sold pursuant to an
effective registration statement under the Securities Act or, unless the Holder
thereof is an affiliate of the Company within the meaning of Rule 144 (or such
successor provision), transferred pursuant to Rule 144 or Rule 904 under the
Securities Act (or any successor provision). Any Restricted Security as to which
such restrictions on transfer shall have expired in accordance with their terms
or shall have terminated may, upon surrender of such Restricted Security for
exchange to the Trustee or any transfer agent in accordance with the provisions
of this Section 3.05, be exchanged for a new Security, of like series, tenor and
aggregate principal amount, which shall not bear the restrictive legend required
by Section 2.05 and shall thereafter be deemed not to be a Restricted Security
for any purpose under this Indenture. The Company shall inform the Trustee in
writing of the effective date of any registration statement registering any
Restricted Securities under the Securities Act.

            No service charge shall be made to a Holder for any registration of
transfer or exchange or redemption of Securities, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 3.03, 3.04, 9.06, 10.15,
10.16 or 11.08 not involving any transfer.

            The Company shall not be required (a) to issue, register the
transfer of or exchange any Security during a period beginning at the opening of
business 15 days before the mailing of a notice of redemption of the Securities
selected for redemption under Section 11.04 and ending at the close of business
on the day of such mailing, or (b) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of Securities being redeemed in part.


<PAGE>
                                      -84-


            Any Holder of a Global Security shall, by acceptance of such Global
Security, agree that transfers of beneficial interests in such Global Security
may be effected only through a book-entry system maintained by the Holder of
such Global Security (or its agent), and that ownership of a beneficial interest
in the Security shall be required to be reflected in a book entry.

            When Securities are presented to the Security Registrar with a
request to register the transfer or to exchange them for an equal principal
amount of Securities of other authorized denominations, the Security Registrar
shall register the transfer or make the exchange as requested if its
requirements for such transactions are met. To permit registrations of transfers
and exchanges, the Company shall execute and the Trustee shall authenticate
Securities at the Security Registrar's request.

            Section 3.06 Mutilated, Destroyed, Lost and Stolen Securities.

            If (a) any mutilated Security is surrendered to the Trustee, or (b)
the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company, each Guarantor, if any, and the Trustee, such security or indemnity, in
each case, as may be required by them to save each of them harmless from any
loss which any of them may suffer if a Security is replaced, then, in the
absence of notice to the Company, any Guarantor or the Trustee that such
Security has been acquired by a bona fide purchaser, the Company shall execute
and upon a Company Order the Trustee shall authenticate and deliver, in exchange
for any such mutilated Security or in lieu of any such destroyed, lost or stolen
Security, a replacement Security of like tenor and principal amount, bearing a
number not contemporaneously outstanding and each Guarantor, if any, under this
Indenture as of such date shall duly endorse its Guarantee thereon.

            Upon the issuance of any replacement Securities under this Section,
the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

            Every replacement Security issued pursuant to this Section in lieu
of any destroyed, lost or stolen Security shall 

<PAGE>
                                      -85-


constitute an original additional contractual obligation of the Company and each
Guarantor, whether or not the destroyed, lost or stolen Security shall be at any
time enforceable by anyone, and shall be entitled to all benefits of this
Indenture equally and proportionately with any and all other Securities duly
issued hereunder.

            The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

            Section 3.07 Payment of Interest; Interest Rights Preserved.

            Interest, including any additional interest payable pursuant to the
Notes Registration Rights Agreement relating to increases in the interest rate
on the Securities, on any Security (and any Additional Amounts payable in
respect thereof) which is payable, and is punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest.

            Any interest on any Security (and any Additional Amounts payable in
respect thereof) which is payable, but is not punctually paid or duly provided
for, on any Interest Payment Date and interest (and any Additional Amounts
payable in respect thereof) on such defaulted interest at the then applicable
interest rate borne by the Securities, to the extent lawful (such defaulted
interest and interest thereon herein collectively called "Defaulted Interest")
shall forthwith cease to be payable to the Holder on the Regular Record Date;
and such Defaulted Interest may be paid by the Company or any Guarantor, at its
election in each case, as provided in subsection (a) or (b) below:

            (a) The Company or any Guarantor may elect to make payment of any
      Defaulted Interest to the persons in whose names the Securities (or their
      respective Predecessor Securities) are registered at the close of business
      on a Special Record Date for the payment of such Defaulted Interest, which
      shall be fixed in the following manner. The Company or a Guarantor shall
      notify the Trustee in writing of the amount of Defaulted Interest proposed
      to be paid on each Security and the date of the proposed payment, and at
      the same time the Company or a Guarantor shall deposit 

<PAGE>
                                      -86-


      with the Trustee an amount of money equal to the aggregate amount proposed
      to be paid in respect of such Defaulted Interest or shall make
      arrangements satisfactory to the Trustee for such deposit prior to the
      date of the proposed payment, such money when deposited to be held in
      trust for the benefit of the persons entitled to such Defaulted Interest
      as in this Subsection (a) provided. Thereupon the Trustee shall fix a
      Special Record Date for the payment of such Defaulted Interest which shall
      be not more than 15 days and not less than 10 days prior to the date of
      the proposed payment and not less than 10 days after the receipt by the
      Trustee of the notice of the proposed payment. The Trustee shall promptly
      notify the Company and, if applicable, such Guarantor in writing of such
      Special Record Date. In the name and at the expense of the Company or such
      Guarantor, the Trustee shall cause notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor to be mailed,
      first-class postage prepaid, to each Holder at its address as it appears
      in the Security Register, not less than 10 days prior to such Special
      Record Date. Notice of the proposed payment of such Defaulted Interest and
      the Special Record Date therefor having been so mailed, such Defaulted
      Interest shall be paid to the persons in whose names the Securities (or
      their respective Predecessor Securities) are registered on such Special
      Record Date and shall no longer be payable pursuant to the following
      subsection (b).

            (b) The Company or a Guarantor may make payment of any Defaulted
      Interest in any other lawful manner not inconsistent with the requirements
      of any securities exchange on which the Securities may be listed, and upon
      such notice as may be required by such exchange, if, after written notice
      given by the Company or such Guarantor to the Trustee of the proposed
      payment pursuant to this subsection (b), such payment shall be deemed
      practicable by the Trustee.

            Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

            Section 3.08 Paying Agents; Discharge of Payment Obligations;
                         Indemnity of Holders.

            (a) The Company may from time to time appoint one or more Paying
Agents and may designate a Paying Agent as Principal Paying Agent under this
Indenture and the Securities. By its execution and delivery of this Indenture,
the Company hereby initially designates and appoints Chase Trust Company as
Principal Paying Agent. Subject to Section 10.03, the Company may act as Paying
Agent.

            (b) Unless the Company shall be acting as Paying Agent as provided
in Section 10.03, the Company shall, by 10:00 A.M. New York time, no later than
one Business Day prior to each interest payment date or principal payment date
on any Securities (whether on maturity, redemption or otherwise) (each, a
"Payment Date"), deposit with the Principal Paying Agent in immediately
available funds a sum sufficient to pay such principal, any premium, and
interest when so becoming due (including any Additional Amounts). The Company
shall request that the bank through which such payment is to be made agree to
supply to the Principal Paying Agent by 10:00 A.M. (New York time) two Business
Days prior to the due date for any such payment an irrevocable confirmation (by
tested telex or authenticated SWIFT MT 100 Message) of its intention to make
such payment. The Principal Paying Agent shall arrange with all Paying Agents
for the payment, from funds furnished by the Company or any Guarantor to the
Trustee pursuant to this Indenture, of the principal, and premium, if any, and
interest (including Additional Amounts, if any) on the Securities and of the
compensation of such Paying Agents for their services as such. All Paying Agents
will hold in trust, for the benefit of Holders or the Trustee, all money held by
such Paying Agent for the payment of principal, or premium, if any, of or
interest on the Securities and shall notify the Trustee of any default by the
Company in making any such payment. The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee and to account for any funds
disbursed by it. Upon complying with this Section 3.08 and the applicable
provisions of Section 10.03, the Paying Agents shall have no further liability
for the money delivered to the Trustee.

            (c) Any payment to be made in respect of the Securities or
Guarantees by the Company or any Guarantor to or to the order of a Paying Agent
shall be in satisfaction pro tanto of the obligations of the Company under the
Securities. The Company shall indemnify the Holders against any failure on the
part of any Paying Agent to pay any sum due in respect of the 

<PAGE>
                                      -88-


Securities and shall pay such sum to the Trustee on demand. This indemnity
constitutes a separate and independent obligation from the other obligations of
the Company under the Securities, shall give rise to a separate and independent
cause of action, will apply irrespective of any waiver granted by the Trustee
and/or any holder of Securities and shall continue in full force and effect
despite any judgment, order, claim, or proof for a liquidated amount in respect
of any sum due under the Indenture, the Securities or any judgment or order.

            Section 3.09 Persons Deemed Owners.

            Prior to and at the time of due presentment for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the person in whose name any Security is registered in the Security
Register as the owner of such Security for the purpose of receiving payment of
principal of, premium, if any, and (subject to Section 3.07) interest on such
Security and for all other purposes whatsoever, whether or not such Security
shall be overdue, and neither the Company, the Trustee nor any agent of the
Company or the Trustee shall be affected by notice to the contrary.

            Section 3.10 Cancellation.

            All Securities surrendered for payment, redemption, repurchase,
registration of transfer or exchange shall be delivered to the Trustee and, if
not already cancelled, shall be promptly cancelled by it. The Company and any
Guarantor may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company or such
Guarantor may have acquired in any manner whatsoever, and all Securities so
delivered shall be promptly cancelled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section 3.09, except as expressly permitted by this Indenture. All
cancelled Securities held by the Trustee shall be destroyed and certification of
their destruction delivered to the Company unless by a Company Order the Company
shall direct that the cancelled Securities be returned to it. The Trustee shall
provide the Company a list of all Securities that have been cancelled from time
to time as requested by the Company.

            Section 3.11 Computation of Interest.

            Interest on the Securities shall be computed on the basis of a
360-day year of twelve 30-day months.

                                      -89-


            Section 3.12 Legal Holidays.

            In any case where any Interest Payment Date, Redemption Date, date
established for the payment of Defaulted Interest or Stated Maturity of any
Security shall not be a Business Day, then (notwithstanding any other provision
of this Indenture or of the Securities) payment of principal, premium, if any,
or interest need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on the
Interest Payment Date, Redemption Date, date established for the payment of
Defaulted Interest or at the Stated Maturity, as the case may be, and no
interest shall accrue with respect to such payment for the period from and after
such Interest Payment Date, Redemption Date, date established for the payment of
Defaulted Interest or Stated Maturity, as the case may be, to the next
succeeding Business Day.

            Section 3.13 CUSIP Number.

            The Company in issuing the Securities may use a "CUSIP" number (if
then generally in use), and if so, the Trustee may use the CUSIP numbers in
notices of redemption or exchange as a convenience to Holders; provided,
however, that any such notice may state that no representation is made as to the
correctness or accuracy of the CUSIP number printed in the notice or on the
Securities, and that reliance may be placed only on the other identification
numbers printed on the Securities. All Series B Securities shall bear identical
CUSIP numbers. The Company shall promptly notify the Trustee in writing of any
change in the CUSIP number of either series of Securities.

            Section 3.14 Book-Entry Provisions for Global Security.

            (a) Each Global Security initially shall (i) be registered in the
name of the Depository for such Global Security or the nominee of such
Depository, (ii) be delivered to the Trustee as custodian for such Depository
and (iii) bear legends as set forth in Section 2.06.

            Members of, or participants in, the Depository ("Agent Members")
shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depository, or the Trustee as its custodian, or
under such Global Security, and the Depository may be treated by the Company,
the Trustee and any agent of the Company or the Trustee as the absolute owner of
such Global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein

<PAGE>
                                      -90-


shall prevent the Company, the Trustee or any agent of the Company or the
Trustee, from giving effect to any written certification, proxy or other
authorization furnished by the Depository or shall impair, as between the
Depository and its Agent Members, the operation of customary practices governing
the exercise of the rights of a holder of any Security.

            (b) Transfers of a Global Security shall be limited to transfers of
such Global Security in whole, but not in part, to the Depository, its
successors or their respective nominees. Interests of beneficial owners in a
Global Security may be transferred in accordance with the rules and procedures
of the Depository and the provisions of Section 3.15. Beneficial owners may
obtain Physical Securities in exchange for their beneficial interests in a
Global Security upon request in accordance with the Depository's and the
Security Registrar's procedures (x) in the case of any Offshore Global Security,
at any time on or after the 41st day following the Issue Date, and (y) in the
case of any U.S. Global Security, at any time. In addition, Physical Securities
shall be issued in exchange for a Global Security if (i) the Depository notifies
the Company that it is unwilling or unable to continue as Depository for a
Global Security or the Depository ceases to be a "clearing agency" registered
under the Exchange Act and, in each case, a successor depository is not
appointed by the Company within 90 days of such notice or such cessation, as the
case may be or (ii) an Event of Default has occurred and is continuing with
respect to any Securities represented by a Global Security and Holders who hold
more than 25% in aggregate principal amount of the Securities at the time
outstanding represented by such Global Security advise the Trustee through the
Depository in writing that the continuation of a book-entry system through the
Depository (or a successor thereto) with respect to such Global Security is no
longer required and the Security Registrar has received a request from the
Depository to issue Physical Securities.

            (c) Any beneficial interest in one of the Global Securities that is
transferred to a person who takes delivery in the form of an interest in the
other Global Security will, upon transfer, cease to be an interest in such
Global Security and become an interest in the other Global Security and,
accordingly, will thereafter be subject to all transfer restrictions, if any,
and other procedures applicable to beneficial interests in such other Global
Security for as long as it remains such an interest.

            (d) In connection with any transfer of a portion of the beneficial
interest in any U.S. Global Security to beneficial owners pursuant to subsection
(b) of this Section, the Security Registrar shall reflect on its books and
records the date and a decrease in the principal amount of such U.S. Global
Security in an amount equal to the principal amount of the beneficial interest
in such U.S. Global Security to be transferred, and the Company shall execute,
and the Trustee shall authenticate and deliver, one or more U.S. Physical
Securities of like tenor and amount.

            (e) In connection with the transfer of an entire Global Security to
beneficial owners thereof pursuant to subsection (b) of this Section, such
Global Security shall be deemed to be surrendered to the Trustee for
cancellation, and the Company shall execute, and the Trustee shall authenticate
and deliver, to each beneficial owner identified by the Depository in exchange
for its beneficial interest in such Global Security, an equal aggregate
principal amount of Physical Securities of authorized denominations.

            (f) Any U.S. Physical Security delivered in exchange for an interest
in any U.S. Global Security pursuant to subsection (b) or subsection (d) of this
Section shall, except as otherwise provided by paragraph (a)(i)(x) or paragraph
(e) of Section 3.15, bear the Private Placement Legend.

            (g) The registered holder of any Global Security may grant proxies
and otherwise authorize any person, including Agent Members and persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Securities.

            (h) QIBs that are beneficial owners of interests in a Global
Security may receive Physical Securities (which shall bear the Private Placement
Legend if required by Section 2.05) in accordance with the procedures of the
Depository. In connection with the execution, authentication and delivery of
such Physical Securities, the Registrar shall reflect on its books and records a
decrease in the principal amount of the relevant Global Security equal to the
principal amount of such Physical Securities, and the Company shall execute and
the Trustee shall authenticate and deliver one or more Physical Securities
having an equal aggregate principal amount.

      any such account are QIBs within the meaning of Rule 144A, and that it is
      aware that the sale to it is being made in reliance on Rule 144A and
      acknowledges that it has received such information regarding the Company
      as it has requested pursuant to Rule 144A or has determined not to request
      such information and that it is aware that the transferor is relying upon

transfer of such Security set forth in this Indenture and in the Private
Placement Legend and agrees that it will transfer such Security only as provided
in this Indenture. The Security Registrar shall not register a transfer of any
Security unless such transfer complies with the restrictions on transfer of such
Security set forth in this Indenture. In connection with any transfer of
Securities to an Institutional Accredited Investor, each such Holder or
beneficial owner agrees by its acceptance of the Securities to furnish the
Security Registrar or the Company such certifications, legal opinions or other
information as such Person may reasonably require to confirm that such transfer
is being made pursuant to an exemption from, or a transaction not subject to,
the registration requirements of the Securities Act; provided that the Security
Registrar shall not be required to determine (but may rely on a determination
made by the Company with respect to) the sufficiency of any such certifications,
legal opinions or other information.

            The Security Registrar shall retain copies of all letters, notices
and other written communications received pursuant to Section 3.13 or this
Section 3.14. The Company shall have the right to inspect and make copies of all
such letters, notices or other written communications at any reasonable time
upon the giving of reasonable written notice to the Security Registrar.

            Upon the Company's exercise under Section 4.01 of the option
applicable to this Section 4.02, the Company and each Guarantor, if any, shall
be deemed to have been discharged from its obligations with respect to the
Defeased Securities on the date the conditions set forth below are satisfied
(hereinafter, "legal defeasance"). For this purpose, such legal defeasance means
that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by the Defeased Securities, which shall thereafter be
deemed to be "Outstanding" only for the purposes of Section 4.05 and the other
Sections of this Indenture referred to in (a) and (b) below, and to have
satisfied all its other obligations under such Securities and this Indenture
insofar as such Securities are concerned (and the Trustee, at the expense of the
Company, and, upon Company Request, shall execute proper instruments
acknowledging the same), except for the following, which shall survive until
otherwise terminated or discharged hereunder: (a) the rights of Holders of
Defeased Securities to receive, solely from the trust fund described in Section
4.04 and as more fully set forth in such Section, payments in respect of the
principal of, premium, if any, and interest on such Securities when such
payments are due, (b) the Company's obligations with respect to such Defeased
Securities under Sections 1.19, 1.20, 3.05, 3.06, 3.07 (first and final
paragraphs only), 7.01, 10.02, 10.03 and 10.08 (for the purposes of applying
section 10.08, if the Trustee (or any qualifying trustee pursuant to Section
4.04) is required by law or by the administration or interpretation thereof to
withhold or deduct any amount for or on account of Taxes from any payment made
from the trust fund described in Section 4.04 under or with respect to the
Securities, such payment shall be deemed to have been made by the Company and
the Company shall be deemed to have been so required to deduct or withhold),
10.11 (but only to the extent such section is applicable to Default of an
Indenture Obligation not defeased) and (c) the rights, powers, trusts, duties
and immunities of the Trustee hereunder, including, without limitation, the
Trustee's rights under Section 6.07, and (d) this Article Four. Subject to
compliance with this Article Four, the Company may exercise its option under

            Section 4.03 Covenant Defeasance.

            Upon the Company's exercise under Section 4.01 of the option

Guarantor, if any, shall be released from its obligations under any covenant or
provision contained in Sections 10.05, 10.06, 10.07, 10.09, 10.10, 10.12, 10.13,
10.14, 10.15, 10.16, 10.17, 10.18, 10.19, 10.20 and 10.21 and the provisions of
Article Eight shall not apply, with respect to the Defeased Securities on and
after the date the conditions set forth below are satisfied (hereinafter,
"covenant defeasance"), and the Defeased Securities shall thereafter be deemed
not to be "Outstanding" for the purposes of any direction, waiver, consent or
declaration or Act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "Outstanding"
for all other purposes hereunder. For this purpose, such covenant defeasance
means that, with respect to the Defeased Securities, the Company and each
Guarantor, if any, may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such Section or
Article, whether directly or indirectly, by reason of any reference elsewhere
herein to any such Section or Article or by reason of any reference in any such
Section or Article to any other provision herein or in any other document and
such omission to comply shall not constitute a Default or an Event of Default
under Section 5.01(c) or, to the extent it relates to such Section or Article,
Section 5.01(d), but, except as specified above, the remainder of this Indenture
and such Defeased Securities shall be unaffected thereby.

            Section 4.04 Conditions to Legal Defeasance or Covenant Defeasance.

            The following shall be the conditions to application of either
Section 4.02 or Section 4.03 to the Defeased Securities:

      making the following payments, specifically pledged as security for, and
      dedicated solely to, the benefit of the Holders of such Securities, (a)
      money in an amount, or (b) U.S. Government Obligations which through the
      scheduled payment of principal, premium, if any, and interest in respect
      thereof in accordance with their terms will provide, not later than one
      day before the due date of any payment, money, in an amount, or (c) a
      combination thereof, in any such case, sufficient, in the opinion of an
      internationally recognized firm of independent public

      accountants expressed in a written certification thereof delivered to the
      Trustee, to pay and discharge and which shall be applied by the Trustee
      (or other qualifying trustee) to pay and discharge, the principal of,
      premium, if any, and interest on the Defeased Securities (including any
      Additional Amounts payable in respect thereof) on the Stated Maturity of
      such principal or installment of principal, premium, if any, or interest
      or (if the Company has made irrevocable arrangements satisfactory to the
      Trustee for the giving of notice of redemption by the Trustee in the name
      and at the expense of the Company) the Redemption Date, as the case may
      be; provided, however, that the Trustee shall have been irrevocably
      instructed to apply such money or the proceeds of such U.S. Government
      Obligations to said payments with respect to the Securities; and provided,
      further, that from and after the time of deposit, the money or U.S.
      Government Obligations deposited shall not be subject to the rights of the
      holders of other Indebtedness of the Company or any Guarantor;

            (2) No Default shall have occurred and be continuing on the date of
      such deposit and after giving effect thereto or, in the case of a legal
      defeasance, insofar as Section 5.01(i), (j) or (k) is concerned, at any
      time during the period ending on the ninety-first day after the date of
      such deposit (it being understood that this condition shall not be deemed
      satisfied until the expiration of such period);

            (3) Neither the Company nor any Guarantor of the Company is an
      "insolvent person" within the meaning of any applicable Bankruptcy Law on
      the date of such deposit or at any time during the period ending on the
      ninety-first day after the date of such deposit (it being understood that
      this condition shall not be deemed satisfied until the expiration of such
      period);

            (4) Such legal defeasance or covenant defeasance shall not cause the
      Trustee for the Securities to have a conflicting interest in violation of
      Section 6.08 and for purposes of the Trust Indenture Act with respect to
      any securities of the Company or any Guarantor;

            (5) Such legal defeasance or covenant defeasance shall not result in
      a breach or violation of, or constitute a default under, or cause or
      permit acceleration of any Indebtedness under, this Indenture or any other
      agree-

      ment or instrument to which the Company or any Guarantor is a party or by
      which it is bound;

            (6) In the case of an election under Section 4.02, the Company shall
      have delivered to the Trustee an Opinion of Counsel in the United States
      reasonably acceptable to the Trustee stating that (x) the Company has
      received from, or there has been published by, the Internal Revenue
      Service a ruling or (y) since the date hereof, there has been a change in
      the applicable United States Federal income tax law, in either case to the
      effect that, and based thereon such opinion shall confirm that, the
      Holders of the Outstanding Securities will not recognize income, gain or
      loss for United States Federal income tax purposes as a result of such
      legal defeasance and will be subject to United States Federal income tax
      on the same amounts, in the same manner and at the same times as would
      have been the case if such legal defeasance had not occurred;

            (7) In the case of an election under Section 4.03, the Company shall
      have delivered to the Trustee an Opinion of Counsel in the United States
      reasonably acceptable to the Trustee to the effect that the Holders of the
      Outstanding Securities will not recognize income, gain or loss for United
      States Federal income tax purposes as a result of such covenant defeasance
      and will be subject to United States Federal income tax on the same
      amounts, in the same manner and at the same times as would have been the
      case if such covenant defeasance had not occurred;

            (8) The Company shall have delivered to the Trustee an Opinion of
      Counsel in Brazil reasonably acceptable to the Trustee to the effect that
      the Holders of the Outstanding Securities will not recognize income, gain
      or loss for Brazilian federal or state income tax or other tax purposes as
      a result of such legal defeasance or covenant defeasance, as applicable,
      and will be subject to Brazilian federal and state income tax and other
      tax on the same amounts, in the same manner and at the same times as would
      have been the case if such legal defeasance or covenant defeasance, as
      applicable, had not occurred. Notwithstanding anything to the contrary in
      this Indenture, this condition may not be waived by any Holder or the
      Trustee;

            (9) The Company shall have delivered to the Trustee, an Opinion of
      Counsel in Brazil and an Opinion of Counsel in the United States each of
      which shall be reasonably ac-

                                     -100-


      ceptable to the Trustee to the effect that, (x) the trust funds
      established pursuant to this Article will not be subject to any rights of
      any other creditors of the Company, any of its Affiliates or Subsidiaries
      or of any Guarantor or holders of other Indebtedness of the Company, any
      of its Affiliates or Subsidiaries or of any Guarantor, and (y) immediately
      following the ninety-first day after the deposit, the trust funds
      established pursuant to this Article will not be subject to the effect of
      any applicable Bankruptcy Law;

            (10) The Company shall have delivered to the Trustee an Officers'
      Certificate reasonably acceptable to the Trustee stating that the deposit
      made by the Company pursuant to its election under Section 4.02 or 4.03
      was not made by the Company with the intent of preferring the Holders or
      any Guarantor over the other creditors of the Company or with the intent
      of defeating, hindering, delaying or defrauding creditors of the Company
      or others; and

            (11) The Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel in the United States, the Federative
      Republic of Brazil and such other jurisdictions as the Trustee may
      reasonably request, in each case, reasonably acceptable to the Trustee and
      each stating that all conditions precedent (other than conditions
      requiring the passage of time) provided for relating to either the
      defeasance under Section 4.02 or the covenant defeasance under Section
      4.03 (as the case may be) have been complied with as contemplated by this
      Section 4.04.

            Opinions required to be delivered under this Section may have such
qualifications as are customary for opinions of the type required and acceptable
to the Trustee.

            Section 4.05 Deposited Money and U.S. Government Obligations To Be
                         Held in Trust; Other Miscellaneous Provisions.

            Subject to the provisions of the last paragraph of Section 10.03,
all money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee (or other person that would qualify to act as
successor trustee under Article Six, collectively for purposes of this Section
4.05, the "Trustee") pursuant to Section 4.04 in respect of the Defeased
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities 

<PAGE>
                                     -101-


and this Indenture, to the payment, either directly or through any Paying Agent
(other than the Company) as the Trustee may determine, to the Holders of such
Securities of all sums due and to become due thereon in respect of principal,
premium, if any, and interest, but such money need not be segregated from other
funds except to the extent required by law.

            The Company shall pay and indemnify the Trustee and hold it harmless
against any tax, fee or other charge imposed on or assessed against the U.S.
Government Obligations deposited pursuant to Section 4.04 or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the Defeased
Securities.

            Section 4.06 Reinstatement.

            If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 4.02 or 4.03, as the case may
be, by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, then the
obligations of the Company and of any Guarantor under this Indenture, the
Securities and the Guarantees, if any, shall be revived and reinstated as though
no deposit had occurred pursuant to Section 4.02 or 4.03, as the case may be,
until such time as the Trustee or Paying Agent is permitted to apply all such
money and U.S. Government Obligations in accordance with Section 4.02 or 4.03,
as the case may be; provided, however, that if the Company makes any payment of
principal, premium, if any, or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money and
U.S. Government Obligations held by the Trustee or Paying Agent.

      acceleration of the maturity thereof; provided, that, in the case of a

            Section 5.02 Acceleration of Maturity; Rescission and Annulment.

            If an Event of Default (other than an Event of Default specified in
Section 5.01(i), (j) or (k) with respect to the Company or in Section 5.01(f))
occurs and is continuing, then and in every such case the Trustee or the Holders
of at least 25% in aggregate principal amount of the Securities Outstanding may,
by written notice, and the Trustee upon the request of the Holders of not less
than 25% in aggregate principal amount of the Securities Outstanding shall,
declare all principal of, premium, if any, on and any accrued and unpaid
interest to the date the Securities become due and payable on all outstanding
Securities (and any Additional Amounts relating thereto) to be immediately due
and payable by a notice in writing to the Company (and to the Trustee, if given
by the Holders). Upon any such declaration such principal, premium, if any, and
interest and any Additional Amounts with respect thereto, shall become
immediately due and payable. If an Event of Default specified in Section
5.01(i), (j) or (k) with respect to the Company or Section 5.01(f) occurs and is
continu-

<PAGE>
                                     -105-


ing, then the principal of, premium, if any, and accrued and unpaid interest, if
any, on all the Securities and any Additional Amounts with respect thereto shall
ipso facto become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder. Except in the case of a
default of a specific amount of premium due, the amount of any premium shall be
determined by interpolation between (a) the premium payable on the next
succeeding date on which either Holders of Securities or the Company may
optionally redeem Securities or on which the Securities mature, as applicable (a
"Payment Date"), and (b) the immediately preceding Payment Date or, if there is
no immediately preceding Payment Date, 0%.

            At any time after a declaration of acceleration has been made or
after any ipso facto acceleration following an Event of Default specified in
Section 5.01(i), (j) or (k) with respect to the Company or in Section 5.01(f)
above and, in any such case, before a judgment or decree for payment of the
money due has been obtained by the Trustee as hereinafter provided in this
Article, the Holders of a majority in aggregate principal amount of the
Securities Outstanding, by written notice to the Trustee, may rescind and annul
such declaration of acceleration or such ipso facto acceleration following an
Event of Default specified in Section 5.01(i), (j), (k) or (f), as the case may
be, and its consequences if:

            (a) the Company has paid or deposited with the Trustee a sum
      sufficient to pay

                  (i) all amounts due the Trustee under Section 6.07, including
            the reasonable compensation, fees, expenses, disbursements and
            advances of the Trustee, its agents and counsel,

                  (ii) all overdue interest on all Securities (including any
            Additional Amounts payable in respect thereof),

                  (iii) the principal of and premium, if any, on any Securities
            (including any Additional Amounts payable in respect thereof) which
            have become due otherwise than by such declaration of acceleration
            and interest thereon (including any Additional Amounts payable in
            respect thereof) at the rate then borne by the Securities, and

<PAGE>
                                     -106-


                  (iv) to the extent that payment of such interest is lawful,
            interest (including any Additional Amounts payable in respect
            thereof) upon overdue interest at the rate then borne by the
            Securities;

            (b) all Events of Default, other than the non-payment of principal
      of, premium, if any, and any accrued and unpaid interest on, the
      Securities which have become due solely as a result of such declaration of
      acceleration, have been cured or waived as provided in Section 5.13; and

            (c) such recission or annulment of such declaration of acceleration
      would not conflict with any judgment or decree of any court of competent
      jurisdiction.

            No such rescission shall affect any subsequent Default or impair any
right consequent thereon.

            Section 5.03 Collection of Indebtedness and Suits for Enforcement by
                         Trustee

            The Company and each Guarantor, if any, covenant that if:

            (a) default is made in the payment of any interest on any Security
      when such interest becomes due and payable and such default continues for
      a period of 30 days or more, or

            (b) default is made in the payment of the principal of or premium,
      if any, on any Security at the Stated Maturity thereof,

the Company and each Guarantor, if any, will, jointly and severally, upon demand
of the Trustee, pay to the Trustee, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for
principal, premium, if any, and interest, with interest upon the overdue
principal, premium, if any, and, to the extent that payment of such interest
shall be legally enforceable, upon overdue installments of interest, at the rate
then borne by the Securities; and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, fees, expenses, disbursements and advances of the
Trustee, its agents and counsel.

<PAGE>
                                     -107-


            If the Company and each Guarantor, if any, fail to pay such amounts
forthwith upon such demand, the Trustee, in its own name and as trustee of an
express trust, may, but is not obligated under this paragraph to, institute a
judicial proceeding for the collection of the sums so due and unpaid and may,
but is not obligated under this paragraph to, prosecute such proceeding to
judgment or final decree, and may, but is not obligated under this paragraph to,
enforce the same against the Company, any Guarantor or any other obligor upon
the Securities and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any Guarantor or
any other obligor upon the Securities, wherever situated.

            If an Event of Default occurs and is continuing, the Trustee may in
its discretion, but is not obligated under this paragraph to, (i) proceed to
protect and enforce its rights and the rights of the Holders under this
Indenture or any Guarantees by such appropriate private or judicial proceedings
as the Trustee shall deem most effectual to protect and enforce such rights,
whether for the specific enforcement of any covenant or agreement contained in
this Indenture or in aid of the exercise of any power granted herein, including,
without limitation, seeking recourse against any Guarantor or (ii) proceed to
protect and enforce any other proper remedy, including, without limitation,
seeking recourse against any Guarantor. No recovery of any such judgment upon
any property of the Company or any Guarantor shall affect or impair any rights,
powers or remedies of the Trustee or the Holders.

            Section 5.04 Trustee May File Proofs of Claims.

            In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the
Securities, including each Guarantor, if any, or the property of the Company or
of such other obligor, the Trustee (irrespective of whether the principal of the
Securities shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand
on the Company for the payment of overdue principal or interest) shall be
entitled and empowered, by intervention in such proceeding or otherwise, but is
not obligated under this paragraph

            (a) to file and prove a claim for the whole amount of principal,
      premium, if any, and interest owing and unpaid in respect of the
      Securities and to file such other

                                     -108-


      papers or documents as may be necessary or advisable in order to have the
      claims of the Trustee (including any claim for the reasonable
      compensation, fees, expenses, disbursements and advances of the Trustee,
      its agents and counsel) and of the Holders allowed in such judicial
      proceeding, and

            (b)  to collect and receive any moneys or other property
      payable or deliverable on any such claims and to distribute the same;

and any Custodian, in any such judicial proceeding, is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, fees, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 6.07 hereof.

            Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

            Section 5.05 Trustee May Enforce Claims Without Possession of
                         Securities.

            All rights of action and claims under this Indenture, the Securities
or any Guarantee may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or the production thereof in any proceeding
relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name and as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
fees, expenses, disbursements and advances of the Trustee, its agents and
counsel, be for the ratable benefit of the Holders of the Securities in respect
of which such judgment has been recovered.

            Section 5.06      Application of Money Collected.

            Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,

<PAGE>
                                     -109-


such money on account of principal, premium, if any, or interest, upon
presentation of the Securities and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

            First: to the Trustee for amounts due under Section 6.07;

            Second: to Holders for interest accrued on the Securities (including
      Additional Amounts payable in respect thereof), ratably, without
      preference or priority of any kind, according to the amounts due and
      payable on the Securities for interest;

            Third: to Holders for principal and premium amounts owing under the
      Securities (including Additional Amounts payable in respect thereof),
      ratably, without preference or priority of any kind, according to the
      amounts due and payable on the Securities for principal and premium; and

            Fourth: the balance, if any, to the Company or, to the extent the
      Trustee collects any amounts from any Guarantor, to such Guarantor.

            The Trustee, upon prior written notice to the Company, may fix a
record date and payment date for any payment to Securityholders pursuant to this
Section 5.06.

            Section 5.07 Limitation on Suits.

            No Holder of any Securities shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless

            (a) such Holder has previously given written notice to the Trustee
      of a continuing Event of Default;

            (b) the Holders of not less than 25% in principal amount of the
      Outstanding Securities shall have made written request to the Trustee to
      institute proceedings in respect of such Event of Default in its own name
      as Trustee hereunder;

            (c) such Holder or Holders have offered to the Trustee reasonable
      indemnity against the costs, expenses and liabilities to be incurred in
      compliance with such request;

<PAGE>
                                     -110-


            (d) the Trustee for 45 days after its receipt of such notice,
      request and offer of indemnity has failed to institute any such
      proceeding; and

            (e) no direction inconsistent with such written request has been
      given to the Trustee during such 45-day period by the Holders of a
      majority in aggregate principal amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture, any Security or any Guarantee to affect, disturb or prejudice
the rights of any other Holders, or to obtain or to seek to obtain priority or
preference over any other Holders or to enforce any right under this Indenture,
any Security or any Guarantee, except in the manner provided in this Indenture
and for the equal and ratable benefit of all the Holders.

            Section 5.08 Unconditional Right of Holders To Receive Principal,
                         Premium and Interest.

            Notwithstanding any other provision in this Indenture, the
Securities or any Guarantee, the Holder of any Security shall have the right,
which is absolute and unconditional, to receive cash payment, in United States
dollars, of the principal of, premium, if any, and (subject to Section 3.07
hereof) interest on such Security (including any Additional Amounts payable in
respect thereof) on the respective Stated Maturities expressed in such Security
(or, in the case of redemption, on the respective Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

            Section 5.09 Restoration of Rights and Remedies.

            If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture, any Security or any Guarantee
and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee or to such Holder, then and in every
such case the Company, each of the Guarantors, the Trustee and the Holders
shall, subject to any determination in such proceeding, be restored severally
and respectively to their former positions hereunder, and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

            Section 5.10 Rights and Remedies Cumulative.

            Except as provided in Section 3.06, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

            Section 5.11 Delay or Omission Not Waiver.

            No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

            Section 5.12 Control by Majority.

            The Holders of a majority in aggregate principal amount of the
Outstanding Securities shall have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, provided, however, that:

            (a) such direction shall not be in conflict with any rule of law or
      with this Indenture, any Security or any Guarantee or expose the Trustee
      to personal liability; and

            (b) the Trustee may take any other action deemed proper by the
      Trustee which is not inconsistent with such direction.

            Section 5.13 Waiver of Past Defaults.

            The Holders of not less than a majority in aggregate principal
amount of the Outstanding Securities may on behalf of the Holders of all the
Securities waive any past Default hereunder and its consequences, except a
Default

<PAGE>
                                     -112-


            (a) in the cash payment in U.S. dollars of the principal of,
      premium, if any, or interest on any Security and any Additional Amount
      payable in respect thereof, or

            (b) in respect of a covenant or provision hereof which under Article
      Nine cannot be modified or amended without the consent of the Holder of
      each Outstanding Security affected.

            Upon any such waiver, such Default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

            Section 5.14 Undertaking for Costs.

            All parties to this Indenture agree, and each Holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities,
or to any suit instituted by any Holder for the enforcement of the payment of
the principal of, premium, if any, or interest on any Security on or after the
respective Stated Maturities expressed in such Security (or, in the case of
redemption, on or after the respective Redemption Dates).

            Section 5.15 Waiver of Stay, Extension or Usury Laws.

            Each of the Company and the Guarantors covenants (to the extent that
it may lawfully do so) that it will not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury or other law wherever enacted, now or at any time
hereafter in force, which would prohibit or forgive the Company or any Guarantor
from paying all or any portion of the princi-

<PAGE>
                                     -113-


pal of, premium, if any, or interest on the Securities contemplated herein or in
the Securities or which may affect the covenants or the performance of this
Indenture; and each of the Company and the Guarantors (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                ARTICLE SIX

                                THE TRUSTEE

            Section 6.01 Certain Duties and Responsibilities.

            (a) Except during the continuance of an Event of Default,

            (1) the Trustee undertakes to perform such duties and only such
      duties as are specifically set forth in this Indenture, and no implied
      covenants or obligations shall be read into this Indenture against the
      Trustee; and

            (2) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture; but
      in the case of any such certificates or opinions which by provision hereof
      are specifically required to be furnished to the Trustee, the Trustee
      shall be under a duty to examine the same to determine whether or not they
      conform to the requirements of this Indenture.

            (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

            (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that no provision of this
Indenture 

<PAGE>
                                     -114-


shall require the Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder, or in the
exercise of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it.

            (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section 6.01.

            Section 6.02 Notice of Defaults.

            Within 30 days after the occurrence of any Default, the Trustee
shall transmit by mail to all Holders, as their names and addresses appear in
the Security Register, notice of such Default hereunder known to the Trustee,
unless such Default shall have been cured or waived; provided, however, that,
except in the case of a Default in the payment of the principal of, premium, if
any, or interest on any Security (including any Additional Amounts payable in
respect thereof) or a Default arising from the occurrence of a Change of
Control, the Trustee shall be protected in withholding such notice if and so
long as a trust committee of Responsible Officers of the Trustee in good faith
determines that the withholding of such notice is in the interest of the
Holders.

            Section 6.03 Certain Rights of Trustee.

            Subject to Section 6.01 hereof and the provisions of Section 315 of
the Trust Indenture Act:

            (a) the Trustee may rely and shall be protected in acting or
      refraining from acting upon any resolution, certificate, statement,
      instrument, opinion, report, notice, request, direction, consent, order,
      approval, appraisal, bond, debenture, note, coupon, security, other
      evidence of indebtedness or other paper or document believed by it to be
      genuine and to have been signed or presented by the proper party or
      parties;

            (b) any request or direction of the Company mentioned herein shall
      be sufficiently evidenced by a Company Request or Company Order and any
      resolution of the Board of the Company or any Guarantor may be
      sufficiently evidenced by a Board Resolution thereof;

<PAGE>
                                     -115-


            (c) the Trustee may consult, at the expense of the Company, with
      counsel and any written advice of such counsel or any Opinion of Counsel
      shall be full and complete authorization and protection in respect of any
      action taken, suffered or omitted by it hereunder in good faith and in
      reliance thereon in accordance with such advice or Opinion of Counsel;

            (d) the Trustee shall be under no obligation to exercise any of the
      rights or powers vested in it by this Indenture at the request or
      direction of any of the Holders pursuant to this Indenture, unless such
      Holders shall have offered to the Trustee reasonable security or indemnity
      against the costs, expenses and liabilities which might be incurred by the
      Trustee in compliance with such request or direction;

            (e) the Trustee shall not be liable for any action taken or omitted
      by it in good faith and believed by it to be authorized or within the
      discretion, rights or powers conferred upon it by this Indenture other
      than any liabilities arising out of its own negligence;

            (f) the Trustee shall not be bound to make any investigation into
      the facts or matters stated in any resolution, certificate, statement,
      instrument, opinion, report, notice, request, direction, consent, order,
      approval, appraisal, bond, debenture, note, coupon, security, other
      evidence of indebtedness or other paper or document unless requested in
      writing so to do by the Holders of not less than a majority in aggregate
      principal amount of the Securities then Outstanding; provided, however,
      that, if the payment within a reasonable time to the Trustee of the costs,
      expenses or liabilities likely to be incurred by it in the making of such
      investigation is, in the opinion of the Trustee, not reasonably assured to
      the Trustee by the security afforded to it by the terms of this Indenture,
      the Trustee may require reasonable indemnity against such expenses or
      liabilities as a condition to proceeding; the reasonable expenses of every
      such investigation shall be paid by the Company or, if paid by the Trustee
      or any predecessor Trustee, shall be repaid by the Company upon demand;
      provided, further, the Trustee in its discretion may make such further
      inquiry or investigation into such facts or matters as it may deem fit,
      and, if the Trustee shall determine to make such further inquiry or
      investigation, it shall be entitled to examine the books, records and
      premises of the Company, personally 

<PAGE>
                                     -116-


      or by agent or attorney during the reasonable business hours of the
      Company; and

            (g) the Trustee may execute any of the trusts or powers hereunder or
      perform any duties hereunder either directly or by or through agents or
      attorneys and the Trustee shall not be responsible for any misconduct or
      negligence on the part of any agent or attorney appointed with due care by
      it hereunder.

            Section 6.04 Trustee Not Responsible for Recitals, Dispositions of
                         Securities or Application of Proceeds Thereof.

            The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company and the Guarantors, and the Trustee assumes no responsibility for
their correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities or of any Guarantee. The
Trustee shall not be accountable for the use or application by the Company of
Securities or the proceeds thereof.

            Section 6.05 Trustee and Agents May Hold Securities; Collections;
                         Etc.

            The Trustee, any Paying Agent, Security Registrar or any other agent
of the Company, in its individual or any other capacity, may become the owner or
pledgee of Securities, with the same rights it would have if it were not the
Trustee, Paying Agent, Security Registrar or such other agent and, subject to
Sections 6.08 and 6.13 hereof and Sections 310 and 311 of the Trust Indenture
Act, may otherwise deal with the Company and receive, collect, hold and retain
collections from the Company with the same rights it would have if it were not
the Trustee, Paying Agent, Security Registrar or such other agent.

            Section 6.06      Money Held in Trust.

            All moneys received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received,
but need not be segregated from other funds except to the extent required herein
or by law. The Trustee shall not be under any liability for interest on any
moneys received by it hereunder.

            Section 6.07 Compensation and Indemnification of Trustee and Its
                         Prior Claim.

            The Company and each Guarantor covenant and agree: (a) to pay to the
Trustee from time to time, and the Trustee shall be entitled to, reasonable
compensation for all services rendered by it hereunder (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust); (b) to reimburse the Trustee and each predecessor Trustee upon
its request for all reasonable expenses, fees, disbursements and advances
incurred or made by or on behalf of it in accordance with any of the provisions
of this Indenture (including the reasonable compensation, fees, and the expenses
and disbursements of its counsel and of all agents and other persons not
regularly in its employ), except any such reasonable expense, disbursement or
advance as may arise from its negligence or bad faith; and (c) to indemnify the
Trustee and each predecessor Trustee for, and to hold it harmless against, any
loss, liability or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of this
Indenture or the trusts hereunder and its duties hereunder, including
enforcement of this Section 6.07. The obligations of the Company and each
Guarantor under this Section to compensate and indemnify the Trustee and each
predecessor Trustee and to pay or reimburse the Trustee and each predecessor
Trustee for expenses, fees, disbursements and advances shall constitute an
additional obligation hereunder and shall survive the satisfaction and discharge
of this Indenture. To secure the obligations of the Company and of each
Guarantor to the Trustee under this Section 6.07, the Trustee shall have a prior
Lien upon all property and funds held or collected by the Trustee as such,
except funds and property paid by the Company or any Guarantor and held in trust
for the benefit of the Holders of particular Securities under this Indenture.
All such payments and reimbursements shall be made with interest at the base
(Prime) rate charged at the time by the Trustee for loans to commercial
customers. The Trustee shall be entitled to file a proof of claim in any
bankruptcy proceeding as a secured creditor for its reasonable compensation,
fees and expenses under this Section 6.07.

            Section 6.08 Conflicting Interests.

            The Trustee shall be subject to and shall comply with the provisions
of Section 310(b) of the Trust Indenture Act.

            Section 6.09 Corporate Trustee Required; Eligibility.

            There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under Trust Indenture Act Sections 310(a)(1) and
310(a)(5) and which shall be a United States banking institution with a combined
capital and surplus of at least US$300,000,000, and have a Corporate Trust
Office in the Borough of Manhattan in The City of New York. If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of United States Federal, state, territorial or District of
Columbia supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, the Trustee shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

            Section 6.10 Resignation and Removal; Appointment of Successor
                         Trustee.

            (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.

            (b) The Trustee, or any trustee or trustees hereinafter appointed,
may at any time resign by giving written notice thereof to the Company. Upon
receiving such notice of resignation, the Company shall promptly appoint a
successor trustee by written instrument executed by authority of the Board of
the Company, a copy of which shall be delivered to the resigning Trustee and a
copy to the successor Trustee. If an instrument of acceptance by a successor
Trustee shall not have been delivered to the Trustee within 20 Business Days
after the giving of such notice of resignation, the resigning Trustee may, or
any Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee. Such court
may thereupon, after such notice, if any, as it may deem proper, appoint a
successor Trustee.

            (c) The Trustee may be removed at any time by an Act of the Holders
of a majority in principal amount of the Out-

<PAGE>
                                     -119-


standing Securities, delivered to the Trustee and to the Company.

            (d) If at any time:

            (1) the Trustee shall fail to comply with the provisions of Section
      310(b) of the Trust Indenture Act in accordance with Section 6.08 hereof
      after written request therefor by the Company or by any Holder who has
      been a bona fide Holder of a Security for at least six months, or

            (2) the Trustee shall cease to be eligible under Section 6.09 hereof
      and shall fail to resign after written request therefor by the Company or
      by any such Holder, or

            (3) the Trustee shall become incapable of acting or shall be
      adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
      property shall be appointed or any public officer shall take charge or
      control of the Trustee or of its property or affairs for the purpose or
      rehabilitation, conservation or liquidation,

then, in any case, (i) the Company by a Board Resolution of its Board may remove
the Trustee, or (ii) subject to Section 5.14, the Holder of any Security who has
been a bona fide Holder of a Security for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee. Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, remove the Trustee and appoint a successor Trustee.

            (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution of its Board, shall promptly appoint a successor
Trustee. If, within one year after such resignation, removal or incapability, or
the occurrence of such vacancy, a successor Trustee shall be appointed by Act of
the Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee and supersede the successor Trustee appointed by the Company.
If no successor Trustee shall have been so appointed by the Company or the
Holders of the Securities and accepted appointment in the manner hereinafter
provided, the Holder of any Security who has been a bona fide Holder for at
least six months may, subject to Sec-

tion 5.14, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the appointment of a successor Trustee.

            (f) The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of Securities as their names and addresses appear in the Security
Register. Each notice shall include the name of the successor Trustee and the
address of its Corporate Trust Office.

            Section 6.11 Acceptance of Appointment by Successor.

            Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee as if originally named as
Trustee hereunder; but, nevertheless, on the written request of the Company or
the successor Trustee, upon payment of amounts due it pursuant to Section 6.07,
such retiring Trustee shall duly assign, transfer and deliver to the successor
Trustee all moneys and property at the time held by it hereunder and shall
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers, duties and obligations of the retiring Trustee. Upon request of
any such successor Trustee, the Company shall execute any and all instruments
for more fully and certainly vesting in and confirming to such successor Trustee
all such rights and powers. Any Trustee ceasing to act shall, nevertheless,
retain a prior claim upon all property or funds held or collected by such
Trustee to secure any amounts then due it pursuant to the provisions of Section
6.07.

            No successor Trustee with respect to the Securities shall accept
appointment as provided in this Section 6.11 unless at the time of such
acceptance such successor Trustee shall be eligible to act as Trustee under this
Article.

            Upon acceptance of appointment by any successor Trustee as provided
in this Section 6.11, the successor shall give notice thereof to the Holders of
the Securities, by mailing such notice to such Holders at their addresses as
they shall appear on the Security Register. If the acceptance of appoint-

<PAGE>
                                     -121-


ment is substantially contemporaneous with the resignation, then the notice
called for by the preceding sentence may be combined with the notice called for
by Section 6.10(f).

            Section 6.12 Merger, Conversion, Amalgamation, Consolidation or
                         Succession to Business.

            Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated or amalgamated, or any corporation resulting
from any merger, conversion, amalgamation or consolidation to which the Trustee
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder without the execution or filing of any paper or any further
act on the part of any of the parties hereto, provided such corporation shall be
eligible under this Article to serve as Trustee hereunder.

            In case at the time such successor to the Trustee under this Section
6.12 shall succeed to the trusts created by this Indenture any of the Securities
shall have been authenticated but not delivered, any such successor to the
Trustee may adopt the certificate of authentication of any predecessor Trustee
and deliver such Securities so authenticated; and, in case at that time any of
the Securities shall not have been authenticated, any successor to the Trustee
under this Section 6.12 may authenticate such Securities either in the name of
any predecessor hereunder or in the name of the successor Trustee; and in all
such cases such certificate shall have the full force which it is anywhere in
the Securities or in this Indenture provided that the certificate of the Trustee
shall have.

            Section 6.13 Preferential Collection of Claims Against Company.

            The Trustee shall comply with Section 311(a) of the Trust Indenture
Act, excluding any creditor relationship listed in Section 311(b) of that Act.
If the present or any future Trustee shall resign or be removed, it shall be
subject to Section 311(a) of the Trust Indenture Act to the extent provided
therein.

convey, lease, transfer or otherwise dispose of all or substantially all of its
properties and assets to any other person or persons, or permit any of its
Subsidiaries to enter into any such transaction or series of transactions if
such transaction or series of transactions, in the aggregate, would result in
the sale, assignment, conveyance, lease, transfer or other disposition of all or

      of transactions on a pro forma basis (including, without limitation, any
      Indebtedness incurred or anticipated to be incurred in connection with or

             (v) such Guarantor shall have delivered to the Trustee an Opinion
      of Counsel reasonably satisfactory to the Trustee, to the effect that the

      being required to make any deduction or withholding on account of
      Brazilian taxes from any payments made under or with respect to the
      Securities, which deduction or withholding is greater than any such
      deduction or withholding which is or would be required had such
      transaction not occurred (unless the Company's and Guarantors' obligations
      to pay Additional Amounts pursuant to Section 10.08 would be sufficient to
      protect all Holders from any liability in respect of such withholding or
      deduction, in which case, the Company shall deliver to the Trustee an
      Officer's Certificate to such effect and confirming the Company's
      obligation to pay such Additional Amounts); and

      transfer, lease or other disposition and, if a supplemental indenture or
      Guarantee is required in connection with such transaction or series of
      transactions to effectuate such assumption, such supplemental indenture or
      Guarantee complies with this Indenture and that all conditions precedent
      provided for in this Indenture relating to such transaction or series of
      transactions have been complied with.

assignment, conveyance, transfer, lease or disposition of all or substantially
all of the properties and assets of the Company or any Guarantor in accordance

other disposition is made, shall succeed to, and be substituted for, and may
exercise every right and power of, the Company or such Guarantor, as the case
may be, under this Indenture, the Securities and/or the Guarantee of any such
Guarantor, as the case may be, with the same effect as if such successor had
been named as the Company or such Guarantor, as the case may be, herein, in the

conveyance, transfer, lease or other disposition to a Subsidiary of the Company

            For all purposes of this Indenture and the Securities (including the
provisions of Sections 10.12, 10.13 and 10.17), subsidiaries of any surviving
entity or Surviving Guarantor shall, upon such transaction or series of
transactions, become Restricted Subsidiaries or Unrestricted Subsidiaries as
provided pursuant to Section 10.10 and all Indebtedness, and all Liens on
property or assets of the Company and the Restricted Subsidiaries immediately
prior to such transaction or series of transactions shall be deemed to have been

            It shall not be necessary for any Act of Holders under this Section
to approve the particular form of any proposed supplemental indenture or other
agreement, instrument or waiver, but it shall be sufficient if such Act shall
approve the substance thereof.

            Section 9.03 Execution of Supplemental Indentures, Agreements and
                         Waivers.

            In executing, or accepting the additional trusts created by, any
supplemental indenture, agreement, instrument or waiver permitted by this
Article Nine or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Section
6.01 hereof) shall be fully protected in relying upon, an Opinion of Counsel and
an Officers' Certificate from each obligor under the Securities entering into
such supplemental indenture, agreement, instrument or waiver, each stating that
the execution of such supplemental indenture, agreement, instrument or waiver
(a) is authorized or permitted by this Indenture and (b) does not violate the
provisions of any agreement or instrument evidencing any other Indebtedness of
the Company, any Guarantor or any Subsidiary of the Company. The Trustee may,
but shall not be obligated to, enter into any such supplemental indenture,
agreement, instrument or waiver which affects the Trustee's own rights, duties
or immunities under this Indenture, the Securities, any Guarantee or otherwise.

            Section 9.04 Effect of Supplemental Indentures.

            Upon the execution of any supplemental indenture under this Article
Nine, this Indenture, the Securities, if applicable, and/or the applicable
Guarantee shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture, the Securities, if applicable,
and/or the applicable Guarantee, as the case may be, for all purposes; and every
Holder of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.

            Section 9.05 Conformity with Trust Indenture Act.

            Every supplemental indenture executed pursuant to this Article Nine
shall conform to the requirements of the Trust Indenture Act as then in effect.

            Section 9.06 Reference in Securities to Supplemental Indentures.

            Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so deter-

<PAGE>
                                     -132-


mine, new Securities so modified as to conform, in the opinion of the Trustee
and the Board of the Company, to any such supplemental indenture may be prepared
and executed by the Company and each Guarantor and authenticated and delivered
by the Trustee in exchange for Outstanding Securities.

            Section 9.07 Record Date.

            The Company may, but shall not be obligated to, fix, with the
approval of the Trustee, a record date for the purpose of determining the
Holders entitled to consent to any supplemental indenture, agreement or
instrument or any waiver, and shall promptly notify the Trustee of any such
record date. If a record date is fixed, those persons who were Holders at such
record date (or their duly designated proxies), and only those persons, shall be
entitled to consent to such supplemental indenture, agreement or instrument or
waiver or to revoke any consent previously given, whether or not such persons
continue to be Holders after such record date. No such consent shall be valid or
effective for more than 90 days after such record date.

            Section 9.08 Revocation and Effect of Consents.

            Until an amendment or waiver becomes effective, a consent to it by a
Holder of a Security is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security, even if a notation of the consent is not made
on any Security. However, any such Holder, or subsequent Holder, may revoke the
consent as to his Security or portion of a Security if the Trustee receives the
notice of revocation before the date the amendment or waiver becomes effective.
An amendment or waiver shall become effective in accordance with its terms and
thereafter bind every Holder.

                                 COVENANTS

            Section 10.01 Payment of Principal, Premium and Interest.

            The Company shall pay the principal of, premium, if any, and
interest on the Securities, and any Additional Amounts 

<PAGE>
                                     -133-


payable in respect thereof, in accordance with the terms of the Securities and
this Indenture.

            Section 10.02 Maintenance of Office or Agency.

            The Company shall maintain in The City of New York an office or
agency where Securities may be presented or surrendered for payment, where
Securities may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served. The office of the Trustee at its Corporate Trust Office
shall be such office or agency of the Company, unless the Company shall
designate and maintain some other office or agency for one or more of such
purposes. The Company shall give prompt written notice to the Trustee of any
change in the location of any such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office, and the
Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

            The Company may also from time to time designate one or more other
offices or agencies (in or outside of The City of New York) where the Securities
may be presented or surrendered for any or all such purposes, and may from time
to time rescind such designation; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in The City of New York for such purposes. The Company shall
give prompt written notice to the Trustee of any such designation or rescission
and any change in the location of any such other office or agency.

            Section 10.03 Money for Security Payments To Be Held in Trust

            If the Company shall at any time act as its own Paying Agent, it
shall, on or before each due date of the principal of, premium, if any, or
interest on any of the Securities, segregate and hold in trust for the benefit
of the Holders entitled thereto a sum sufficient to pay the principal, premium,
if any, or interest so becoming due (and any Additional Amounts related thereto)
until such sums shall be paid to such persons or otherwise disposed of as herein
provided, and shall promptly notify the Trustee of its action or failure so to
act.

<PAGE>
                                     -134-


            If the Company is not acting as Paying Agent, the Company shall, on
or before each due date of the principal of, premium, if any, or interest on,
any Securities, deposit with a Paying Agent a sum in same day funds sufficient
to pay the principal, premium, if any, or interest so becoming due (and any
Additional Amounts related thereto) in the manner set forth in Section 3.08,
such sum to be held in trust for the benefit of the Holders entitled to such
principal, premium or interest, and (unless such Paying Agent is the Trustee)
the Company shall promptly notify the Trustee of such action or any failure so
to act.

            If the Company is not acting as Paying Agent, the Company shall
cause each Paying Agent other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section 10.03, that such Paying Agent shall:

            (a) hold all sums held by it for the payment of the principal of,
      premium, if any, or interest on Securities (and any Additional Amounts
      related thereto) in trust for the benefit of the Holders entitled thereto
      until such sums shall be paid to such Holders or otherwise disposed of as
      herein provided;

            (b) give the Trustee notice of any Default by the Company or any
      Guarantors (or any other obligor upon the Securities) in the making of any
      payment of principal of, premium, if any, or interest on the Securities
      (or any Additional Amounts related thereto);

            (c) at any time during the continuance of any such Default, upon the
      written request of the Trustee, forthwith pay to the Trustee all sums so
      held in trust by such Paying Agent; and

            (d) acknowledge, accept and agree to comply in all aspects with the
      provisions of this Indenture relating to the duties, rights and
      liabilities of such Paying Agent.

            The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any 

<PAGE>
                                     -135-


Paying Agent to the Trustee, such Paying Agent shall be released from all
further liability with respect to such money.

            Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of, premium, if
any, or interest on any Security (or any Additional Amounts related thereto) and
remaining unclaimed for two years after such principal, premium, if any, or
interest has become due and payable shall be paid to the Company upon receipt of
a Company Request therefor, or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Security shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in The New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
shall be repaid to the Company.

            Section 10.04 Corporate Existence.

            Subject to Article Eight, the Company shall do or cause to be done
all things necessary to preserve and keep in full force and effect the corporate
existence, rights (charter and statutory), licenses and franchises of the
Company and each of the Restricted Subsidiaries; provided, however, that the
Company shall not be required to preserve any such right, license or franchise
if the Board of the Company shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and the
Restricted Subsidiaries as a whole and that the loss thereof is not adverse in
any material respect to the Holders; provided, further, that the foregoing shall
not prohibit a sale, transfer or conveyance of a Restricted Subsidiary of the
Company or any of its assets in compliance with the terms of this Indenture.

            Section 10.05 Payment of Taxes and Other Claims.

            The Company shall pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (a) all taxes, assessments
and governmental charges levied or imposed (i) upon the Company or any of its
Restricted Subsidi-

<PAGE>
                                     -136-


aries or (ii) upon the income, profits or property of the Company or any of its
Restricted Subsidiaries and (b) all lawful claims for labor, materials and
supplies, which, if unpaid, could reasonably be expected to become a Lien upon
the property of the Company or any of its Restricted Subsidiaries; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim which (i) is
being contested in good faith by appropriate proceedings properly instituted and
diligently conducted and (ii) if unpaid, would not materially adversely affect
the business, properties or financial condition of the Company and Restricted
Subsidiaries, taken as a whole.

            Section 10.06 Maintenance of Properties.

            The Company shall cause all properties owned by the Company or any
of the Restricted Subsidiaries or used or held for use in the conduct of their
respective businesses to be maintained and kept in good condition, repair and
working order (reasonable wear and tear excepted) and supplied with all
necessary equipment and shall cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof except where the failure to
do so would not materially adversely affect the business, properties or
financial condition of the Company and the Restricted Subsidiaries, taken as a
whole. Section 10.06 shall not prevent the Company from discontinuing the
maintenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business or the business of any
of the Restricted Subsidiaries and is not disadvantageous in any material
respect to the Holders.

            Section 10.07 Insurance.

            The Company shall at all times keep its material properties and the
Restricted Subsidiaries' material properties which are of an insurable nature
insured with insurers, believed by the Company in good faith to be financially
sound and responsible, against loss or damage to the extent that property of
similar character is usually and customarily so insured by corporations
similarly situated and owning like properties (which may include self-insurance,
if reasonable and in comparable form to that maintained by companies similarly
situated).

            Section 10.08 Payment of Additional Amounts.

            (a) All payments made by the Company or any Guarantor under or with
respect to the Securities or any Guarantee 

<PAGE>
                                     -137-


shall be made free and clear of and without withholding or deduction for or on
account of any present or future Taxes imposed or levied by or on behalf of any
Taxing Authority of the Federative Republic of Brazil or of Japan, unless the
Company or such Guarantor, as the case may be, is required to withhold or deduct
any amount for or on account of Taxes by law or by the interpretation or
administration thereof. If the Company or any Guarantor is required to withhold
or deduct any amount for or on account of Taxes imposed by a Taxing Authority of
the Federative Republic of Brazil or of Japan from any payment made under or
with respect to the Securities or any Guarantee of such Guarantor, the Company
or such Guarantor, as the case may be, shall pay such additional amounts
("Additional Amounts") as may be necessary so that the net amount received by
each Holder of Securities (including Additional Amounts) after such withholding
or deduction shall not be less than the amount the Holder would have received if
such Taxes had not been withheld or deducted. No such Additional Amounts shall
be payable with respect to a payment made to a Holder of Securities (an
"Excluded Holder") with respect to any Tax which would not have been imposed,
payable or due: (i) but for the fact that the Holder (or where the Holder is an
estate, nominee, trust, partnership or corporation, any fiduciary, settlor,
beneficiary, member or shareholder) is a domiciliary, national or resident of,
or engaging in business, maintaining a permanent establishment or physically
present in, Brazil or Japan; (ii) but for the failure to comply with a request
by the Company or any Guarantor to satisfy any certification, identification or
other reporting requirements, whether imposed by statute, treaty, regulation or
administrative practices, concerning nationality, residence or connection with
Brazil or Japan; or (iii) if, where presentation is required, the presentation
for payment had occurred within 30 days after the date such payment was due and
payable or was provided for, whichever is later. The obligation to pay Taxes
shall not apply to (a) any estate, inheritance, gift, sales, transfer, personal
property or any similar Tax or (b) any Tax which is payable otherwise than by
deduction or withholding from payments made under or with respect to the
Securities. The Company or the Guarantor, as applicable, shall (i) make such
withholding or deduction and (ii) remit the full amount deducted or withheld to
the relevant authority (the "Taxing Authority") in accordance with applicable
law. The Company or the Guarantor, as applicable, shall obtain certified copies
of tax receipts evidencing the payment of any Taxes so deducted or withheld from
each Taxing Authority imposing such Taxes and shall provide such certified copy
to the Principal Paying Agent for prompt forwarding to the holder. The Company
or the Guarantor, as applicable, shall attach to each certified 

<PAGE>
                                     -138-


copy a certificate stating (x) that the amount of withholding tax evidenced by
the certified copy was paid in connection with payments in respect of the
principal amount of Securities then outstanding and (y) the amount of such
withholding tax paid per US$1,000 of principal amount of the Securities. If the
Company or any Guarantor conducts business in any jurisdiction (the "Taxing
Jurisdiction") other than the Federative Republic of Brazil or Japan in a manner
which causes Holders to be liable for taxes on payments under the Securities or
any Guarantee, as the case may be, for which they would not have been so liable
but for such conduct of business in the Taxing Jurisdiction, the Additional
Amounts provision described above shall be considered to apply to such Holders
as if references in such provision to "Taxes" included taxes imposed by way of
deduction or withholding by such Taxing Jurisdiction.

            (b) The Company or such Guarantor, as the case may be, shall
indemnify and hold harmless each Holder of Securities (other than an Excluded
Holder) and upon written request of each Holder of Securities (other than an
Excluded Holder), reimburse each such Holder, for the amount of (i) any such
Taxes so levied or imposed on and paid by such Holder as a result of payments
made under or with respect to the Securities, (ii) any liability (including
penalties, interest and expenses) arising under or with respect to the foregoing
clause (i), and (iii) any Taxes so levied or imposed with respect to any
reimbursement under the foregoing clauses (i) or (ii), so that the net amount
received by such Holder after such reimbursement shall not be less than the net
amount the Holder would have received if Taxes on such reimbursement had not
been imposed or levied, but excluding any Taxes on such Holder's net income.

            (c) At least 30 days prior to each date on which any payment under
or with respect to the Securities is due and payable (unless such obligation to
pay Additional Amounts arises after the 30th day prior to such date, in which
case it shall be promptly thereafter), if the Company or any Guarantor shall be
obligated to pay Additional Amounts with respect to such payment, the Company or
such Guarantor shall deliver to the Trustee and each Paying Agent an Officers'
Certificate stating the fact that such Additional Amounts shall be payable and
shall specify by country the amounts to be payable and shall set forth such
other information necessary to enable the Trustee and each Paying Agent to pay
such Additional Amounts to Holders on the payment date. Each Officers'
Certificate shall be relied upon until receipt of a further Officers'
Certificate addressing such matters. The Company and any such Guarantor shall
indemnify the Trustee and any Paying Agent for, and hold 

<PAGE>
                                     -139-


them harmless against, any loss, liability or expense reasonably incurred
without negligence or bad faith on their part arising out of or in connection
with actions taken or omitted by any of them in reliance on any Officers'
Certificate furnished pursuant to this Section. Whenever in this Indenture there
is mentioned, in any context, the payment of principal, premium, if any,
interest or any other amount payable under or with respect to any Security, such
mention shall be deemed to include mention of the payment of Additional Amounts
provided for in this Section 10.08, to the extent that, in such context,
Additional Amounts are, were or would be payable in respect thereof pursuant to
the provisions of this Section 10.08 and express mention of the payment of
Additional Amounts in any provisions hereof shall not be construed as excluding
Additional Amounts in those provisions hereof where such express mention is not
made.

            (d) The obligations of the Company and the Guarantors under this
Section 10.08 shall survive the termination of this Indenture and the payment of
all other amounts under or with respect to the Securities.

            Section 10.09 Provision of Financial Statements and Other
                          Information.
 
            (a) Whether or not the Company has a class of securities registered
under the Exchange Act, the Company shall furnish without cost to each Holder of
Securities and file with the Commission (whether or not the Company is a public
reporting company at the time), the Trustee and the Initial Purchasers: (i)
within 120 days after the end of each fiscal year of the Company, annual reports
on Form 20-F (or any successor form) containing the information required to be
contained therein (or required in such successor form); (ii) within 60 days
after the end of each of the first three fiscal quarters of each fiscal year,
reports on Form 6-K (or any successor form) containing substantially the same
information required to be contained in Form 10-Q (or required in any successor
form); and (iii) promptly from time to time after the occurrence of an event
required to be therein reported, such other reports on Form 6-K (or any
successor form) containing substantially the same information required to be
contained in Form 8-K (or required in any successor form). Each of the reports
shall be prepared in accordance with U.S. GAAP consistently applied and shall be
prepared in accordance with the applicable rules and regulations of the
Commission. Prior to the effectiveness of the Exchange Offer Registration
Statement (as defined in the Registration Rights Agreement) or the filing of any
Shelf Reg-

<PAGE>
                                     -140-


istration Statement with the Commission, the Company shall file with the Trustee
and provide the Initial Purchasers all of the information that would have been
required to have been filed with the Commission pursuant to clauses (i), (ii)
and (iii) of this Section 10.09(b). Each report pursuant to this Section
10.09(b) shall be prepared in accordance with U.S. GAAP consistently applied and
shall be prepared in accordance with the applicable rules and regulations of the
Commission.

            (b) At its own expense, the Company shall supply without cost to
each Holder of the Securities and file with the Trustee within fifteen days
after the Company is required to file the same with the Commission, copies of
any other annual or quarterly reports or other information, documents or reports
which the Company may be required to file with the Commission pursuant to
Section 13(a), 13(c) or 15(d) of the Exchange Act. The Company shall also comply
with the other provisions of Section 314(a) of the Trust Indenture Act.

            (c) At any time when the Company is not subject to Section 13 or
15(d) of the Securities Exchange Act of 1934, upon the request of a Holder of a
Series A Security, the Company shall promptly furnish or cause to be furnished
such information as is specified pursuant to Rule 144A(d)(4) under the
Securities Act (or any successor provision thereto) to such Holder or to a
prospective purchaser of such Series A Security designated by such Holder, as
the case may be, in order to permit compliance by such Holder with Rule 144A
under the Securities Act.

            Section 10.10 Limitation on Designations of Unrestricted
                          Subsidiaries.

            (a) The Company may designate any Subsidiary of the Company as an
"Unrestricted Subsidiary" under this Indenture (a "Designation") only if:

             (i)  no Default shall have occurred and be continuing at the
      time of or after giving effect to such Designation; and

            (ii) the Company would be permitted under this Indenture to make an
      Investment under all applicable provisions of Section 10.13 at the time of
      Designation (assuming the effectiveness of such Designation) in an amount
      (the "Designation Amount") equal to the Fair Market Value of the
      Investment of the Company and the Restricted Subsidiaries in such
      Subsidiary on such date.

<PAGE>
                                     -141-


            In the event of any such Designation, the Company shall be deemed to
have made an Investment constituting a Restricted Payment pursuant to Section
10.13 hereof for all purposes of this Indenture in the Designation Amount and
upon such Designation, the Subsidiary that is the subject of such Designation
shall be deemed to be released from its Guarantee, if any. Further, the Company
shall not, and shall not permit any Restricted Subsidiary to, at any time (x)
guarantee any Indebtedness of any Unrestricted Subsidiary (including any
undertaking, agreement or instrument evidencing such Indebtedness); provided
that the Company or any Restricted Subsidiary may pledge Capital Stock or
Indebtedness of any Unrestricted Subsidiary on a non-recourse basis such that
the pledgee has no claim whatsoever against the pledgor other than to obtain
such pledged property or (y) become or be directly or indirectly liable for any
Indebtedness of any Unrestricted Subsidiary or (z) be directly or indirectly
liable for any Indebtedness which provides that the holder thereof may (upon
notice, lapse of time or both) declare a default thereon or cause the payment
thereof to be accelerated or payable prior to its final scheduled maturity upon
the occurrence of a default with respect to any Indebtedness of any Unrestricted
Subsidiary (including any right to take enforcement action against such
Unrestricted Subsidiary), except in the case of clause (x) or (y) to the extent
permitted under Section 10.13 hereof.

            (b) In addition, the Company may revoke any Designation of a
Subsidiary as an Unrestricted Subsidiary (a "Revocation") if:

            (i) no Default shall have occurred and be continuing at the time of
      and after giving effect to such Revocation; and

            (ii) all Liens and Indebtedness of such Unrestricted Subsidiary
      outstanding immediately following such Revocation would, if incurred at
      such time, have been permitted to be incurred for all purposes of this
      Indenture; and

            (iii) such Subsidiary issues a Guarantee to the extent required
      under Section 10.18.

            All Designations and Revocations shall be evidenced by Board
Resolutions of the Company delivered to the Trustee certifying compliance with
the foregoing provisions.

            Section 10.11 Statement by Officers as to Default.

            (a) The Company shall deliver to the Trustee, within 90 days after
the end of each Fiscal Year of the Company ending after the date hereof, an
Officers' Certificate of the Company signed by the chairman or a chief executive
officer of the Company, and by the principal financial officer or principal
accounting officer of the Company, stating (i) that a review of the activities
of the Company during the preceding Fiscal Year has been made under the
supervision of the signing officers with a view to determining whether the
Company has kept, observed, performed and fulfilled its obligations under this
Indenture, and (ii) that, to the knowledge of each officer signing such
certificate, the Company has kept, observed, performed and fulfilled each and
every covenant and condition contained in this Indenture and is not in default
in the performance or observance of any of the terms, provisions, conditions and
covenants hereof (or, if a Default shall have occurred, describing all such
Defaults of which such officers may have knowledge, their status and what action
the Company is taking or proposes to take with respect thereto).

            (b) When any Default has occurred and is continuing, or if the
Trustee or any Holder or the trustee for or the holder of any other evidence of
Indebtedness of the Company or any Restricted Subsidiary gives any notice or
takes any other action with respect to a claimed default (other than with
respect to Indebtedness (other than Indebtedness evidenced by the Securities) in
an aggregate principal amount of less than US$5,000,000 (or, if non-U.S. dollar
denominated, the U.S. Dollar Equivalent thereof)), the Company shall promptly
notify the Trustee of such Default, notice or action and shall deliver to the
Trustee by registered or certified mail or by telegram, telex or facsimile
transmission an Officers' Certificate specifying such event, notice or other
action within ten Business Days after the Company becomes aware of such

      Company (x) as capital contributions to the Company after the Issue Date
      or (y) from the issue or sale (other than to a Restricted Subsidiary) of

      Restricted Subsidiary plus (d) in the case of the disposition or repayment
      of any Investment constituting a Restricted Payment (other than an
      Investment made pursuant to clause (v) of Section 10.13(b)) made after the
      Issue Date an amount equal to the lesser of the return of capital with
      respect to such Investment and the cost of such Investment, in either
      case, less the cost of the disposition of such Investment plus (e) in the
      case of the Revocation of the Designation of a Subsidiary as an
      Unrestricted Subsidiary, an amount equal to the consolidated net

      Subsidiary while it was an Unrestricted Subsidiary) in such Subsidiary on
      the date of Revocation but not in an amount exceeding the sum of (1) the
      Designation Amount with respect to such Subsidiary and (2) the net amount

      received by the Company upon the issuance of Capital Stock either upon the
      conversion of convertible Indebtedness or in exchange for outstanding

      the net cash proceeds received upon the issuance of such Indebtedness,

            The Company shall not, and shall not permit, cause, or suffer any
Restricted Subsidiary to, conduct any business or enter into any transaction or
series of related transactions with or for the benefit of any of their
respective Affiliates or any beneficial holder of ten percent or more of any
class of Capital Stock of the Company or any officer or director of the Company
or any Restricted Subsidiary (each an "Affiliate Transaction"), except on terms
that are fair and reasonable to the Company or such Restricted Subsidiary, as

other property having a Fair Market Value in excess of US$2,000,000 (or, to the
extent non-U.S. dollar denominated, the U.S. Dollar Equivalent of such amount)

<PAGE>
                                     -147-


that the Board of Directors of the Company (including a majority of the
Disinterested Directors) has determined that such transaction complies with the
foregoing provisions. In addition to the foregoing, with respect to any
Affiliate Transaction involving aggregate consideration in excess of
US$5,000,000 (or, to the extent non-U.S. dollar denominated, the U.S. Dollar
Equivalent of such amount) or more, the Company must obtain a written opinion
(delivered to the Trustee) from an Independent Financial Advisor stating that
the terms of such Affiliate Transaction to the Company or the Restricted

            Notwithstanding the foregoing, the restrictions set forth in this
covenant shall not apply to (i) transactions with or among, the Company and/or
any of the Restricted Subsidiaries; provided in any such case, no officer,
director or beneficial holder of 10% or more of any class of Capital Stock of

            Section 10.15 Disposition of Proceeds of Asset Sales.

            (a) The Company shall not, and shall not permit any Restricted
Subsidiary to, make any Asset Sale unless (i) the Company or such Restricted
Subsidiary, as the case may be, receives consideration at the time of such Asset
Sale at least equal to the Fair Market Value of the shares or assets sold or
otherwise disposed of and (ii) at least 75% of such consideration consists of
cash or Cash Equivalents (provided that the following shall be deemed cash for
purposes of this provision and be treated as Net Cash Proceeds, subject to
application as 

<PAGE>
                                     -148-


hereinafter provided: the amount of (x) any liabilities (as shown on the balance
sheet or in the notes thereto of the Company or such Restricted Subsidiary) of
the Company or such Restricted Subsidiary that are assumed (and from which the
Company or such Restricted Subsidiary is unconditionally released) in connection
with such Asset Sale by the transferee or purchaser of such assets or on behalf
of such transferee or purchaser by a third party and (y) any notes or other
assets received by the Company or such Restricted Subsidiary from such
transferee or purchaser that are immediately sold or transferred (on a
non-recourse basis) for cash or Cash Equivalents). To the extent the Net Cash
Proceeds of any Asset Sale are not required to be applied to repay, and
permanently reduce the commitments under, any Specified Indebtedness or are
required but are not so applied, the Company or such Restricted Subsidiary, as
the case may be, may apply such Net Cash Proceeds within 365 days thereof, to an
investment in properties and assets that shall be used in a Permitted Business
(or in Capital Stock of any person that shall become a Restricted Subsidiary as
a result of such investment if such person principally owns properties and
assets that shall be used in a Permitted Business) of the Company or any
Restricted Subsidiary ("Replacement Assets"). Pending the final application of
any such Net Cash Proceeds in accordance with the second sentence of this
paragraph or to an Asset Sale Offer, the Company or such Restricted Subsidiary
may invest such Net Cash Proceeds in any manner not prohibited by this Indenture
and may temporarily repay Specified Indebtedness. The Pro Rata Share of Net Cash
Proceeds from any Asset Sale that are neither used to repay, and permanently
reduce the commitments under, any Specified Indebtedness nor invested in
Replacement Assets within such 365-day period shall constitute "Excess Proceeds"
subject to disposition as provided in Section 10.15(b).

            (b) Within 30 days after the aggregate amount of Excess Proceeds
equals or exceeds US$10,000,000 (or, to the extent non-U.S. Dollar denominated,
the U.S. Dollar Equivalent of such amount), the Company shall make an offer to
purchase (an "Asset Sale Offer"), from all Holders of the Securities, Securities
having an aggregate purchase price equal to such Excess Proceeds at a price in
cash equal to 100% of the outstanding principal amount thereof plus accrued and
unpaid interest, if any, to the purchase date (including any Additional Amounts
payable in respect thereof). Each Asset Sale Offer shall remain open for a
period of 20 Business Days or such longer period as may be required by law. To
the extent that the aggregate purchase price for Securities tendered pursuant to
an Asset Sale Offer is less than the Excess Proceeds available for 

<PAGE>
                                     -149-


such offer, the Company and the Restricted Subsidiaries may use such deficiency
for general corporate purposes. If the aggregate purchase price for the
Securities validly tendered and not withdrawn by Holders thereof exceeds the
Excess Proceeds available for such offer, Securities to be purchased shall be
selected on a pro rata basis or as nearly pro rata as practicable. Upon
completion of such Asset Sale Offer, the amount of Excess Proceeds shall be
reset to zero.

            (c) The Company shall comply with all applicable tender offer laws
and regulations, including, to the extent applicable, the requirements of
Section 14(e) of, and Rule 14e-1 under, the Exchange Act, and any other
applicable United States or foreign securities laws or regulations, including
applicable laws of the Federative Republic of Brazil or any State thereof, and
any applicable requirements of any securities exchange on which the Notes are
listed, in connection with the repurchase of Securities pursuant to the Asset
Sale Offer. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 10.15, the Company shall
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations under this Section 10.15 by virtue
thereof.

            Section 10.16 Change of Control Offer.

            In the event of a Change of Control (the date of such occurrence,
the "Change of Control Date"), the Company shall notify the Holders of
Securities in writing of such occurrence and will make an offer to purchase (the
"Change of Control Offer"), on a Business Day (the "Change of Control Payment
Date") not later than 60 days following the Change of Control Date, all
Securities then Outstanding at a purchase price equal to 101% of the principal
amount thereof plus accrued and unpaid interest, if any, to the Change of
Control Payment Date (including any Additional Amounts payable in respect
thereof) (the "Change of Control Purchase Price"). Failure to mail the notice on
the date specified below or to have satisfied the foregoing condition precedent
by the date that the notice is required to be mailed shall constitute an Event
of Default under Section 5.01(c).

            Notice of a Change of Control Offer shall be mailed by the Company
not later than 10 days after the Change of Control Date to the Trustee, who, not
less than 25 days nor more than 45 days before the Change of Control Payment
Date, shall mail such notice to each of the Holders of Securities at their last
registered address with a copy to the Paying Agent. The 

<PAGE>
                                     -150-

Control Payment Date. The notice, which shall govern the terms of the Change of
Control Offer, shall include such disclosures as are required by law and shall

      Section 10.16 and that all Securities tendered into the Change of Control
      Offer will be accepted for payment;

            (b) the purchase price (including the amount of accrued interest, if
      any) for each Security, the Change of Control Payment Date, the last date
      on which the Change of Control Notice (as defined below) must be given to
      a Paying Agent, the date on which the Change of Control Offer expires and
      the names and addresses of any Paying Agent;

            (c) that any Security not tendered for payment will continue to
      accrue interest in accordance with its terms;

            (d) that, unless the Company shall default in the payment of the
      Change of Control Purchase Price, any Security accepted for purchase
      pursuant to the Change of Control Offer shall cease to accrue interest
      after the Change of Control Payment Date;

            (e) that Holders electing to have Securities purchased pursuant to a
      Change of Control Offer will be required to surrender their Securities to
      a Paying Agent at the address specified in the notice prior to 5:00 p.m.,
      New York City time, on the Change of Control Payment Date and must
      complete a notice of such election in the form of Exhibit D hereto or such
      other form proposed by the Company and acceptable to the Trustee and the
      Paying Agent (the "Change of Control Purchase Notice");

            (f) that Holders of Securities will be entitled to withdraw their
      election if the Paying Agent receives, not later than 5:00 p.m., New York
      City time, on the Change of Control Payment Date, a tested telex,
      facsimile transmission or letter setting forth the name of the Holder, the
      principal amount of Securities the Holder delivered for purchase, the
      Security certificate number (if any) and a statement that such Holder is
      withdrawing his election to have such Securities purchased;

<PAGE>
                                     -151-


            (g) that Holders whose Securities are purchased only in part will be
      issued Securities equal in principal amount to the unpurchased portion of
      the Securities surrendered;

            (h) the instructions that Holders must follow in order to tender
      their Securities and the procedures for withdrawing a Change in Control
      Purchase Notice; and

            (i) information concerning the business of the Company, the most
      recent annual and quarterly reports of the Company filed with the
      Commission pursuant to the Exchange Act and/or such other information or
      reports prepared pursuant to Section 10.09, a description of material
      developments in the Company's business, information with respect to pro
      forma historical financial information after giving effect to such Change
      of Control and such other information concerning the circumstances and
      relevant facts regarding such Change of Control and Change of Control
      Offer as would be material to a Holder of Securities in connection with
      the decision of such Holder as to whether or not it should tender
      Securities pursuant to the Change of Control Offer, including, but not
      limited to, the events causing such Change of Control and the date such
      Change of Control is deemed to have occurred.

money in United States dollars, in immediately available funds, sufficient to

with an Officers' Certificate setting forth the Securities or portions thereof
tendered to and accepted for payment by the Company. The Paying Agent shall
promptly mail or deliver to the Holders of Securities so accepted payment in an
amount equal to such Change of Control Purchase Price, and the Trustee shall
promptly authenticate and mail or deliver to such Holders a new Security equal
in principal amount to any unpurchased portion of each Security surrendered. Any
Securities not so accepted shall be promptly mailed or delivered by the Company
to the Holder thereof. The Company will publicly announce the results of the
Change of Control Offer not later than the first Business Day following the
Change of Control Payment Date. Notwithstanding the foregoing provisions of this

Section 10.16, the Company shall not be required to make a Change of Control
Offer in order to satisfy the requirements of this Section 10.16 if a third
party makes the Change of Control Offer in the manner, at the times and
otherwise in full compliance with the requirements applicable to a Change of
Control Offer made by the Company and purchases all Securities validly tendered
and not withdrawn pursuant to such Change of Control Offer; provided, however,
that any such third party shall be subject to Section 10.08 in respect of any

modified by replacing "Company" with the name of the third party) and this
covenant shall be deemed satisfied only if such third party complies with
Section 10.08 (as modified) or if the Company satisfies such third party's
obligations under such Section.

            The Company shall comply, to the extent applicable, with the

of Brazil or any State thereof, and any applicable requirements of any
securities exchange on which the Securities are listed, in connection with the
repurchase of Securities pursuant to a Change of Control Offer. To the extent
that the provisions of any securities laws or regulations conflict with the
provisions of this Section 10.16, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under this Section 10.16 by virtue thereof.

            Notwithstanding anything herein to the contrary, any Holder
delivering to the Paying Agent, at the office of the Paying Agent or an office

            Section 10.17 Limitation on Liens Securing Certain Indebtedness.

            The Company shall not, and shall not permit any Restricted
Subsidiary to, create, incur, assume or suffer to exist any Liens of any kind
against or upon any of its property or assets, or any proceeds therefrom, which
secure either (x) Subordinated Debt Securities unless the Securities and the
Guarantees, as applicable, are secured by a Lien on such property, assets or
proceeds that is senior in priority to the Liens securing such Subordinated Debt
Securities or (y) Pari Passu Debt Securities unless the Securities and the
Guarantees, as applicable, are equally and ratably secured with the Liens
securing such Pari Passu Debt Securities. The Company shall not create, incur or
suffer to exist any Lien of any kind (other than the Lien of the Trustee
pursuant to the Escrow Agreement) against or upon the Collateral and will not
terminate the Lien of the Trustee pursuant to the Escrow Agreement on the
Collateral.

            Section 10.18 Issuance of Guarantees by Material Restricted
                          Subsidiaries; Release of Guarantees.

            Each Material Restricted Subsidiary shall be a guarantor of the
Securities (each, a "Guarantor" and, collectively the "Guarantors"). Each
Guarantor shall fully and unconditionally guarantee (collectively, the
"Guarantees"), jointly and severally, on a senior unsecured basis to each holder
of a Security the due and punctual payment of the principal of, premium, if any,
and interest on, and all other amounts owing in respect of such Security (and
any Additional Amounts payable in respect thereof) and under this Indenture.
Each Guarantor shall deliver a written instrument in the form attached to this
Indenture evidencing its Guarantee and shall, upon request by the Trustee or any
Holder promptly endorse its Guarantee on any Security for which such request is
made; provided, however, that every Holder shall have the full benefit of and
every right and privilege relating to each Guarantee whether or not such
Guarantee shall have been endorsed upon any Security.

            Pursuant to each Guarantee, if the Company defaults in payment of
any amount owing in respect of any Security, the Guarantor will be obligated to
duly and punctually pay the same. Each Guarantor covenants and agrees that its
obligations under its Guarantee shall be unconditional, irrespective of the
validity, regularity or enforceability of the Securities or this Indenture, the
absence of any action to enforce the same

                          REDEMPTION OF SECURITIES

            Section 11.01 Redemption Generally.

            The Securities may be redeemed (i) in whole or in part, at any time
on or after June 6, 2001, at the option of the Company, subject to the
conditions and at the redemption prices specified in the forms of Security,
together with accrued but unpaid interest to the redemption date or (ii) on or
prior to June 6, 2000, at the option of the Company, subject to the conditions
and at the redemption price specified in the form of Security, with the proceeds
of one or more Significant Equity Offerings or (iii) in whole, but not in part,
at the option of the Company, at any time, if pursuant to the tax redemption
provisions of the Securities, at the price specified in the forms of Security.

            Section 11.02 Applicability of Article.

            Redemption of Securities at the election of the Company or
otherwise, as permitted or required by any provision of this Indenture or the
Securities, shall be made in accordance with such provision and this Article.

            Section 11.03 Election To Redeem; Notice to Trustee.

            The election of the Company to redeem any Securities pursuant to
Section 11.01 shall be evidenced by a Board Resolution and an Officers'
Certificate. In case of any redemption at the election of the Company, the
Company shall, at least 45 days prior to the Redemption Date fixed by the
Company in such Board Resolution and Officers' Certificate (unless a shorter
notice period shall be satisfactory to the Trustee), notify the Trustee in
writing of such Redemption Date and of the principal amount of Securities to be
redeemed.

            Section 11.04 Selection by Trustee of Securities To Be Redeemed.

            If less than all the Securities are to be redeemed pursuant to
Section 11.01, the particular Securities or portions thereof to be redeemed
shall be selected not more than 60 days and not less than 30 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities not previously
called for redemption by lot, pro rata or by such other method as the Trustee in
its sole discretion deems fair and appropriate and in such manner as complies
with the requirements of the principal securities exchange, if any, on which the
Securities being redeemed are listed and the Depository; provided that any
redemption pursuant to the provisions of the Securities relating to a
Significant Equity Offering shall be made on a pro rata basis or as nearly pro
rata basis as practicable (subject to the procedures of the Depository). In any
such proration, the Trustee shall make such adjustments, reallocations and
eliminations as it shall deem proper to the end that the principal amount of
each Security so prorated shall be equal to an authorized denomination, by
increasing or decreasing or eliminating the amount which would be allocable to
any Security on the basis of exact proportion by an amount not exceeding
US$5,000. The Trustee shall make the selection from the Securities Outstanding
and not previously called for redemption. The Trustee shall promptly notify the
Company and the Security Registrar in writing of such Securities selected for
redemption and, in the case of Securities selected for partial redemption, the
principal amount to be redeemed. The Trustee may select for redemption portions
of the principal amount of Securities that have denominations equal to or larger
than US$1,000 principal amount.

            For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption of Securities shall relate, in
the case of any Security redeemed or to be redeemed only in part, to the portion
of the principal amount of such Security which has been or is to be redeemed.

            Section 11.05 Notice of Redemption.

            (a) In the case of any redemption pursuant to Section 11.01, notice
of redemption shall be given by first-class mail, postage prepaid, mailed not
less than 30 nor more than 60 days prior to the Redemption Date, to each Holder
of Securities to be redeemed, at the address of such Holder appearing in the
Security Register.

      amount of such Security to be redeemed and that after the Redemption Date
      upon surrender of such Security, a new Security or Securities in the
      aggregate principal amount equal to the unredeemed portion thereof shall
      be issued;

            (v) that Securities called for redemption must be surrendered to the
      Paying Agent to collect the Redemption Price;

            (vi) that on the Redemption Date the Redemption Price shall become
      due and payable upon each such Security or portion thereof, together with
      accrued and unpaid interest to the Redemption Date (and any Additional
      Amounts related thereto), and that (unless the Company shall default in
      payment of the Redemption Price) interest thereon shall cease to accrue on
      and after said date;

            (vii) the place or places where such Securities are to be
      surrendered for payment of the Redemption Price;

            (viii) the CUSIP number, if any, relating to such Securities; and

            (ix) the paragraph of the Securities pursuant to which the
      Securities are being redeemed.

            (b) Notice of redemption pursuant to Section 11.05(a) shall be given
by the Company or, at the Company's written request, by the Trustee in the name
and at the expense of the Company.

            (c) The notice if mailed in the manner herein provided shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice 

<PAGE>
                                     -159-


to the Holder of any Security designated for redemption as a whole or in part
shall not affect the validity of the proceedings for the redemption of any other
Security.

            Section 11.06 Deposit of Redemption Price.

            One day prior to any Redemption Date, the Company shall deposit with
the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 10.03) an
amount of money in same day funds sufficient to pay the Redemption Price of, and
accrued interest on, all the Securities or portions thereof which are to be
redeemed on that date (together with any Additional Amounts).

            Section 11.07 Securities Payable on Redemption Date.

            Notice of redemption having been given as aforesaid, the Securities
so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified and from and after such date (unless the
Company shall default in the payment of the Redemption Price) such Securities
shall cease to bear interest. Upon surrender of any such Security for redemption
in accordance with said notice, such Security shall be paid by the Company at
the Redemption Price; provided, however, that installments of interest whose
Stated Maturity is on or prior to the Redemption Date, shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such on the relevant Regular Record Dates according to the terms and the
provisions of Section 3.07.

            If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and premium, if any, shall,
until paid, bear interest from the Redemption Date, at the rate then borne by
such Security.

            Section 11.08 Securities Redeemed or Purchased in Part.

            Any Security which is to be redeemed or purchased only in part shall
be surrendered to the Paying Agent at the office or agency maintained for such
purpose pursuant to Section 10.02 (with, if the Company, the Security Registrar
or the Trustee so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to, the Company, the Security Registrar or the
Trustee duly executed by the Holder thereof or such Holder's attorney duly
authorized in writing),

                                     -160-


and the Company shall execute, and the Trustee shall authenticate and deliver to
the Holder of such Security without service charge, a new Security or
Securities, of any authorized denomination as requested by such Holder in
aggregate principal amount equal to, and in exchange for, the portion of the
principal of the Security so surrendered that is not redeemed or purchased.

proceeds of the Escrow Account. Each Holder of Securities, by its acceptance
thereof, consents and agrees to the terms of the Escrow Agreement (including,
without limitation, the provisions providing for foreclosure and disbursement of
Collateral) as the same may be in effect or may be amended from time to time in
accordance with its terms and authorizes and directs the Escrow Agent and the

required by the provisions of the Escrow Agreement, to assure and confirm to the
Trustee the security interest in the Collateral contemplated by the Escrow
Agreement or in any part thereof, as from time to time constituted, so as to
render the same available for the security and benefit of this Indenture with
respect to, and of, the Securities, according to the intent and purposes

the Escrow Agreement to create and maintain (to the extent possible under
applicable Law) as security for the obligations of the Company hereunder, a
valid and enforceable perfected first priority Lien in and on all the
Collateral, in favor of the Trustee for the benefit of the Trustee, predecessor
trustees, and the Holders of Securities, superior to and prior to the rights of
all third Persons and subject to no other Liens. The Trustee shall have no
responsibility for perfecting or maintaining the perfection of the Trustee's
security interest in the Collateral or for filing any instrument, document or
notice in any public office at any time or times.

            (b) The Escrow Agreement shall further provide that in the event a
portion of the Securities has been retired by the Company, depending upon the
amount available in the Escrow Account, funds representing the interest payments
which have not previously been made on such retired Securities shall, upon the
written request of the Company to the Escrow Agent and the Trustee, be paid to
the Company upon compliance with the release of collateral provisions of the TIA
and upon the receipt of a notice relating thereto from the Trustee.

be created by the Escrow Agreement and reciting with respect to the security
interests in the Collateral the details of such action, or (ii) stating that in
the opinion of such counsel no such action is necessary to make such Lien

Escrow Agreement and reciting with respect 

<PAGE>
                                     -162-


to the security interests in the Collateral the details of such action or
referring to prior Opinions of Counsel in which such details are given and (B)
based on relevant laws as in effect on the date of such Opinion of Counsel, all
financing statements and continuation statements have been executed and filed
that are necessary as of such date and during the succeeding 12 months fully to
preserve and protect, to the extent such protection and preservation are

automatically released by operation of Section 9-306 of the Uniform Commercial
Code or other similar law, no Collateral shall be released from the Lien and
security interest created by the Escrow Agreement pursuant to the provisions of
the Escrow Agreement, other than to the Holders pursuant to the terms thereof,
unless there shall have been delivered to the Trustee the certificate required
by Section 12.03(d) and Section 12.04.

            (c) At any time when a Default shall have occurred and be continuing
and the maturity of the Securities issued on the Issue Date shall have been
accelerated (whether by declaration or otherwise), no Collateral shall be
released pursuant to the provisions of the Escrow Agreement, and no release of
Collateral in contravention of this Section 12.03(c) shall be effective as
against the Holders of Securities, except for the disbursement of all Available
Funds (as defined in the Escrow Agreement) to the Trustee pursuant to Section
6(b) of the Escrow Agreement.

            (d) The release of any Collateral from the Liens and security
interests created by the Escrow Agreement shall not be deemed to impair the
security under this Indenture in contravention of the provisions hereof if and
to the extent the Collateral is released pursuant to the terms hereof or
pursuant to the terms of the Escrow Agreement. To the extent applicable,

Trustee may, without the consent of the Holders of Securities, on behalf of the
Holders of Securities, take all actions it deems necessary or appropriate in
order to (a) enforce any of the terms of the Escrow Agreement and (b) collect

Agreement or this Indenture, and such suits and proceedings as the Trustee may

                          GUARANTEE OF SECURITIES

            Section 14.01 Unconditional Guarantee.

            Subject to the provisions of this Article Fourteen, each Guarantor
upon becoming a Guarantor in accordance with the provisions of Section 10.18 or
otherwise, jointly and severally unconditionally and irrevocably guarantee (such
guarantee to be referred to herein as a "Guarantee") to each Holder of a
Security authenticated and delivered by the Trustee and to the Trustee and its
successors and assigns, irrespective of the validity and enforceability of this
Indenture, the Securities or the obligations of the Company or any other
Guarantors to the Holders or the Trustee hereunder or thereunder, that: (a) the
principal of, premium, if any, and interest on the Securities (and any
Additional Amounts payable thereon) shall be duly and punctually paid in full
when due, whether at maturity, upon redemption at the option of Holders pursuant
to the provisions of the Securities relating thereto, by acceleration or
otherwise, and interest on the overdue principal and (to the extent permitted by
law) interest, if any, on the Securities and all other obligations of the
Company or the Guarantors to the Holders or the Trustee hereunder or thereunder
(including amounts due the Trustee under Section 6.07 hereof) and all other
Indenture Obligations shall be promptly paid in full or performed, all in
accordance with the terms hereof and thereof; and (b) in case of any extension
of time of payment or renewal of any Securities or any of such other Indenture
Obligations, the same shall be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at Stated
Maturity, by acceleration or otherwise. Failing payment when due of any amount
so guaranteed, or failing performance of any other obligation of the Company to
the Holders, for whatever reason, each Guarantor shall be obligated to pay, or
to perform or cause the performance of, the same immediately. An Event of
Default under this Indenture or the Securities shall 

<PAGE>
                                     -167-


constitute an event of default under this Guarantee, and shall entitle the
Holders of Securities to accelerate the obligations of the Guarantors hereunder
in the same manner and to the same extent as the obligations of the Company.

            Each Guarantor agrees, to the fullest extent permitted by applicable
law, that its obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Securities or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any holder
of the Securities with respect to any provisions hereof or thereof, any release
of any other Guarantor, the recovery of any judgment against the Company, any
action to enforce the same, whether or not a Guarantee is affixed to any
particular Security, or any other circumstance which might otherwise constitute
a legal or equitable discharge or defense of a guarantor. Each Guarantor waives,
to the fullest extent permitted by applicable law, the benefit of diligence,
presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first
against the Company, protest, notice and all demands whatsoever and covenant,
that its Guarantee shall not be discharged except by complete performance of the
obligations contained in the Securities, this Indenture and its Guarantee. This
Guarantee is a guarantee of payment and not of collection. If any Holder or the
Trustee is required by any court or otherwise to return to the Company or to any
Guarantor, or any custodian, trustee, liquidator or other similar official
acting in relation to the Company or such Guarantor, any amount paid by the
Company or such Guarantor to the Trustee or such Holder, this Guarantee, to the
extent theretofore discharged, shall be reinstated in full force and effect, to
the fullest extent permitted by applicable law. Each Guarantor further agrees
that, as between it, on the one hand, and the Holders of Securities and the
Trustee, on the other hand, (a) subject to this Article Fourteen, the maturity
of the obligations guaranteed hereby may be accelerated as provided in Article
Five hereof for the purposes of this Guarantee, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the
obligations guaranteed hereby, and (b) in the event of any acceleration of such
obligations as provided in Article Five hereof, such obligations (whether or not
due and payable) shall forthwith become due and payable by the Guarantors for
the purpose of this Guarantee.

            This Guarantee shall remain in full force and effect and continue to
be effective should any petition be filed by or against the Company for
liquidation or reorganization, should 

<PAGE>
                                     -168-


the Company become insolvent or make an assignment for the benefit of creditors
or should a receiver or trustee be appointed for all or any significant part of
the Company's assets, and shall, to the fullest extent permitted by law,
continue to be effective or be reinstated, as the case may be, if at any time
payment and performance of the Securities are, pursuant to applicable law,
rescinded or reduced in amount, or must otherwise be restored or returned by any
obligee on the Securities, whether as a "voidable preference," "fraudulent
transfer" or otherwise, all as though such payment or performance had not been
made. In the event that any payment, or any part thereof, is rescinded, reduced,
restored or returned, the Securities shall, to the fullest extent permitted by
law, be reinstated and deemed reduced only by such amount paid and not so
rescinded, reduced, restored or returned.

            No stockholder, officer, director, employee or incorporator, past,
present or future, or any Guarantor, as such, shall have any personal liability
under this Guarantee by reason of his, her or its status as such stockholder,
officer, director, employee or incorporator.

            Each Guarantor shall have the right to seek contribution from any
other Guarantor so long as the exercise of such right does not impair the rights
of the Holders under this Guarantee.

            Section 14.02 Execution and Delivery of Guarantee.

            To further evidence the Guarantee set forth in Section 14.01, each
Guarantor hereby agrees that a notation of such Guarantee, substantially in the
form included in Exhibit A of this Indenture, shall be endorsed on each Security
authenticated and delivered by the Trustee upon request by any Holder or the
Trustee. Such Guarantee shall be executed on behalf of each Guarantor by either
manual or facsimile signature of two Officers of each Guarantor, each of whom,
in each case, shall have been duly authorized to so execute by all requisite
corporate action. The validity and enforceability of any Guarantee shall not be
affected by the fact that it is not affixed to any particular Security.

            Each of the Guarantors hereby agrees that its Guarantee set forth in
Section 14.01 shall remain in full force and effect notwithstanding any failure
to endorse on each Security a notation of such Guarantee.

<PAGE>
                                     -169-


            If an Officer of a Guarantor whose signature is on this Indenture or
a Guarantee no longer holds that office at the time the Trustee authenticates
the Security on which such Guarantee is endorsed or at any time thereafter, such
Guarantor's Guarantee of such Security shall be valid nevertheless.

            The delivery of any Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of any Guarantee
set forth in this Indenture on behalf of each Guarantor.

            Section 14.03 Additional Guarantors.

            Any person may become a Guarantor by executing and delivering to the
Trustee (a) a supplemental indenture satisfactory to the Trustee, which subjects
such person to the provisions of this Indenture as a Guarantor, (b) a Guarantee
substantially in the form of Exhibit A hereto and (c) an Opinion of Counsel to
the effect that such supplemental indenture and Guarantee have been duly
authorized and executed by such person and constitute the legal, valid, binding
and enforceable obligations of such person (subject to customary exceptions
concerning bankruptcy, fraudulent conveyance, creditors' rights, laws of general
application and equitable principles).

            Section 14.04 Release of a Guarantor.

            (a) If no Default exists or would exist under this Indenture, upon
 the sale or disposition of all of the Capital Stock of a Guarantor by the
 Company or a Restricted Subsidiary of the Company in a transaction constituting
 an Asset Sale the Net Cash Proceeds of which are applied in accordance with
 Section 10.15, or upon the consolidation or merger of a Guarantor with or into
 any person in compliance with Article Eight (in each case, other than to the
 Company or an Affiliate of the Company or a Restricted Subsidiary), such
 Guarantor and each Subsidiary of such Guarantor that is also a Guarantor shall
 be deemed automatically and unconditionally released and discharged from all
 obligations under this Article Fourteen and all related Guarantees without any
 further action required on the part of the Trustee or any Holder; provided,
 however, that each such Guarantor is sold or disposed of in accordance with
 this Indenture.

            (b) The Trustee shall deliver an appropriate instrument evidencing
 the release of a Guarantor upon receipt of a request of the Company or such
 Guarantor accompanied by an Officers' Certificate and an Opinion of Counsel
 certifying as to 

<PAGE>
                                     -170-


the compliance with this Section 14.04. Any Guarantor not so released or the
entity surviving such Guarantor, as applicable, shall remain or be liable under
its Guarantee as provided in this Article Fourteen.

            The Trustee shall execute any documents reasonably requested by the
Company or a Guarantor in order to evidence the release of such Guarantor from
its obligations under its Guarantee endorsed on the Securities and under this
Article Fourteen.

            Except as set forth in Articles Eight and Ten and this Section
14.04, nothing contained in this Indenture or in any of the Securities shall
prevent any consolidation or merger of a Guarantor with or into the Company or
another Guarantor or shall prevent any sale or conveyance of the property of a
Guarantor as an entirety or substantially as an entirety to the Company or
another Guarantor.

            Section 14.05 Waiver of Subrogation.

            Until this Indenture is discharged and all of the Securities are
discharged and paid in full, each Guarantor hereby irrevocably waives and agrees
not to exercise any claim or other rights which it may now or hereafter acquire
against the Company that arise from the existence, payment, performance or
enforcement of the Company's obligations under the Securities or this Indenture
and such Guarantor's obligations under this Guarantee and this Indenture, in any
such instance including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution, indemnification, and any right to
participate in any claim or remedy of the Guaranteed Parties against the
Company, whether or not such claim, remedy or right arises in equity, or under
contract, statute or common law, including, without limitation, the right to
take or receive from the Company, directly or indirectly, in cash or other
property or by set-off or in any other manner, payment or security on account of
such claim or other rights. If any amount shall be paid to any Guarantor in
violation of the preceding sentence and any amounts owing to the Trustee or the
Holders of Securities under the Securities, this Indenture, or any other
document or instrument delivered under or in connection with such agreements or
instruments, shall not have been paid in full, such amount shall have been
deemed to have been paid to such Guarantor for the benefit of, and held in trust
for the benefit of, the Guaranteed Parties and shall forthwith be paid to the
Trustee for the benefit of such Holders to be credited and applied to the
obligations in favor of the Guaranteed Parties, 

<PAGE>
                                     -171-


whether matured or unmatured, in accordance with the terms of this Indenture.
Each Guarantor acknowledges that it will receive direct and indirect benefits
from the financing arrangements contemplated by this Indenture and that the
waiver set forth in this Section 14.05 is knowingly made in contemplation of
such benefits.

            Section 14.06 Immediate Payment.

            Each Guarantor agrees to make immediate payment to the Trustee on
behalf of the Guaranteed Parties of all Guaranteed Obligations owing or payable
to the respective Guaranteed Parties upon receipt of a demand for payment
therefor by the Trustee to such Guarantor in writing.

            Section 14.07 No Set-Off.

            Each payment to be made by a Guarantor hereunder in respect of the
Guaranteed Obligations shall be payable in the currency or currencies in which
such Guaranteed Obligations are denominated, and shall be made without set-off,
counterclaim, reduction or diminution of any kind or nature.

            Section 14.08 Obligations Absolute.

            The obligations of each Guarantor hereunder are and shall be
absolute and unconditional and any monies or amounts expressed to be owing or
payable by each Guarantor hereunder which may not be recoverable from such
Guarantor on the basis of a guarantee shall be recoverable from such Guarantor
as a primary obligor and principal debtor in respect thereof.

            Section 14.09 Obligations Continuing.

            The obligations of each Guarantor hereunder shall be continuing and
shall remain in full force and effect until all the Guaranteed Obligations have
been paid and satisfied in full. Each Guarantor agrees with the Trustee that it
will from time to time deliver to the Trustee suitable acknowledgments of this
continued liability hereunder and under any other instrument or instruments in
such form as counsel to the Trustee may advise and as will prevent any action
brought against it in respect of any default hereunder being barred by any
statute of limitations now or hereafter in force and, in the event of the
failure of a Guarantor so to do, it hereby irrevocably appoints the Trustee the
attorney and agent of such Guarantor to make, execute and deliver such written
acknowledgment or acknowledgments or other instruments as may from time to time
become nec-

<PAGE>
                                     -172-


essary or advisable, in the judgment of the Trustee on the advice of counsel, to
fully maintain and keep in force the liability of such Guarantor hereunder.

            Section 14.10 Obligations Not Reduced.

            The obligations of each Guarantor hereunder shall not be satisfied,
reduced or discharged by any intermediate payment or satisfaction of any part of
the principal, interest, fees and other monies or amounts which may at any time
be or become owing or payable under or by virtue of or otherwise in connection
with the Securities or this Indenture.

            Section 14.11 Obligations Reinstated.

            The obligations of each Guarantor hereunder shall, to the fullest
extent permitted by law, continue to be effective or shall be reinstated, as the
case may be, if at any time any payment which would otherwise have reduced the
obligations of any Guarantor hereunder (whether such payment shall have been
made by or on behalf of the Company or by or on behalf of a Guarantor) is
rescinded or reclaimed from any of the Guaranteed Parties upon the insolvency,
bankruptcy, liquidation or reorganization of the Company or any Guarantor or
otherwise, all as though such payment had not been made. If demand for, or
acceleration of the time for, payment by the Company is stayed upon the
insolvency, bankruptcy, liquidation or reorganization of the Company, all such
indebtedness otherwise subject to demand for payment or acceleration shall
nonetheless be payable by each Guarantor as provided herein.

            Section 14.12 Obligations Not Affected.

            The obligations of each Guarantor hereunder, to the fullest extent
permitted by law, shall not be affected, impaired or diminished in any way by
any act, omission, matter or thing whatsoever, occurring before, upon or after
any demand for payment hereunder (and whether or not known or consented to by
any Guarantor or any of the Guaranteed Parties) which, but for this provision,
might constitute a whole or partial defense to a claim against any Guarantor
hereunder or might operate to release or otherwise exonerate any Guarantor from
any of its obligations hereunder or otherwise affect such obligations, whether
occasioned by default of any of the Guaranteed Parties or otherwise, including,
without limitation:

            (1) any limitation of status or power, disability, incapacity or
      other circumstance relating to the Company 

<PAGE>
                                     -173-


      or any other person, including any insolvency, bankruptcy, liquidation,
      reorganization, readjustment, composition, dissolution, winding-up or
      other proceeding involving or affecting the Company or any other person;

            (2) any irregularity, defect, unenforceability or invalidity in
      respect of any indebtedness or other obligation of the Company or any
      other person under this Indenture, the Securities or any other document or
      instrument;

            (3) any failure of the Company, whether or not without fault on its
      part, to perform or comply with any of the provisions of this Indenture or
      the Securities, or to give notice thereof to a Guarantor;

            (4) the taking or enforcing or exercising or the refusal or neglect
      to take or enforce or exercise any right or remedy from or against the
      Company or any other person or their respective assets or the release or
      discharge of any such right or remedy;

            (5) the granting of time, renewals, extensions, compromises,
      concessions, waivers, releases, discharges and other indulgences to the
      Company or any other person;

            (6) any change in the time, manner or place of payment of, or in any
      other term of, any of the Securities, or any other amendment, variation,
      supplement, replacement or waiver of, or any consent to departure from,
      any of the Securities or this Indenture, including, without limitation,
      any increase or decrease in the principal amount of or premium, if any, or
      interest on any of the Securities;

            (7) any change in the ownership, control, name, objects, businesses,
      assets, capital structure or constitution of the Company or a Guarantor;

            (8) any merger or amalgamation of the Company or a Guarantor with
      any person or persons;

            (9) the occurrence of any change in the laws, rules, regulations or
      ordinances of any jurisdiction by any present or future action of any
      governmental authority or court amending, varying, reducing or otherwise
      affecting, or purporting to amend, vary, reduce or otherwise affect, any
      of the Guaranteed Obligations or the obligations of a Guarantor under its
      Guarantee; and

<PAGE>
                                     -174-


            (10) any other circumstance (other than by complete, irrevocable
      payment or release of its Guarantee in accordance with this Indenture)
      that might otherwise constitute a legal or equitable discharge or defense
      of the Company under this Indenture or the Securities or of a Guarantor in
      respect of its Guarantee hereunder.

            Section 14.13 Waiver.

            Without in any way limiting the provisions of Section 14.01 hereof,
each Guarantor hereby, to the fullest extent permitted by law, waives notice of
acceptance hereof, notice of any liability of any Guarantor hereunder, notice or
proof of reliance by the Guaranteed Parties upon the obligations of any
Guarantor hereunder, and diligence, presentment, demand for payment on the
Company, protest, notice of dishonor or non-payment of any of the Guaranteed
Obligations, or other notice or formalities to the Company or any Guarantor of
any kind whatsoever. Each of the Guarantors hereby waives, to the fullest extent
permitted by applicable law, all benefits set forth in articles 1491, 1494,
1498, 1499, 1500 and 1503 of the Brazilian Civil Code, articles 261 and 262 of
the Brazilian Commercial Code and article 595 of the Brazilian Civil Procedure
Code.

            Section 14.14 No Obligation To Take Action Against Company.

            Neither the Trustee nor any of the other Guaranteed Parties shall
have any obligation to enforce or exhaust any rights or remedies or to take any
other steps under any security for the Guaranteed Obligations or against the
Company or any other person or any property of the Company or any other person
before the Trustee is entitled to demand payment and performance by any or all
Guarantors of their liabilities and obligations under their Guarantees or under
this Indenture.

            Section 14.15 Dealing with the Company and Others.

            The Guaranteed Parties, without releasing, discharging, limiting or
otherwise affecting in whole or in part the obligations and liabilities of any
Guarantor hereunder and without the consent of or notice to any Guarantor, may,
to the fullest extent permitted by applicable law:

            (1) grant time, renewals, extensions, compromises, concessions,
      waivers, releases, discharges and other indulgences to the Company or any
      other person;

<PAGE>
                                     -175-


            (2) take or abstain from taking security or collateral from the
      Company or from perfecting security or collateral of the Company;

            (3) release, discharge, compromise, realize, enforce or otherwise
      deal with or do any act or thing in respect of (with or without
      consideration) any and all collateral, mortgages or other security given
      by the Company or any third party with respect to the obligations or
      matters contemplated by this Indenture or the Securities;

            (4) accept compromises or arrangements from the Company;

            (5) apply all monies at any time received from the Company or from
      any security upon such part of the Guaranteed Obligations as the
      Guaranteed Parties may see fit or change any such application in whole or
      in part from time to time as the Guaranteed Parties may see fit; and

            (6) otherwise deal with, or waive or modify their right to deal
      with, the Company and all other Persons and any security as the Guaranteed
      Parties or the Trustee may see fit.

            Section 14.16 Default and Enforcement.

            If any Guarantor fails to pay in accordance with Section 14.06
hereof, the Trustee may proceed in its name as trustee hereunder in the
enforcement of the Guarantee of any such Guarantor and such Guarantor's
Obligations thereunder and hereunder by any remedy provided by law, whether by
legal proceedings or otherwise, and to recover from such Guarantor the
Guaranteed Obligations.

            Section 14.17 Amendment, Etc.

            No amendment, modification or waiver of any provision of this
Indenture relating to any Guarantor or consent to any departure by any Guarantor
or any other person from any such provision will in any event be effective
unless it is signed by such Guarantor and the Trustee.

            Section 14.18 Acknowledgment.

            Each Guarantor hereby acknowledges communication of the terms of
this Indenture and the Securities and consents to and approves of the same.

            Section 14.19 Costs and Expenses.

            Each Guarantor shall pay on demand by the Trustee any and all costs,
fees and expenses (including, without limitation, legal fees) incurred by the
Trustee, its agents, advisors and counsel or any of the Guaranteed Parties in
enforcing any of their rights under any Guarantee.

            Section 14.20 No Merger or Waiver; Cumulative Remedies.

            No Guarantee shall operate by way of merger of any of the
obligations of the Guarantor under any other agreement, including, without
limitation, this Indenture. No failure to exercise and no delay in exercising,
on the part of the Trustee or the other Guaranteed Parties, any right, remedy,
power or privilege hereunder or under the Indenture or the Securities, shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, remedy, power or privilege hereunder or under this Indenture or the
Securities preclude any other or further exercise thereof or the exercise of any
other right, remedy, power or privilege. The rights, remedies, powers and
privileges in the Guarantee and under this Indenture, the Securities and any
other document or instrument between a Guarantor and/or the Company and the
Trustee are cumulative and not exclusive of any rights, remedies, powers and
privilege provided by law.

            Section 14.21 Guarantee in Addition to Other Obligations.

            The obligations of each Guarantor under its Guarantee and this
Indenture are in addition to and not in substitution for any other obligations
to the Trustee or to any of the Guaranteed Parties in relation to this Indenture
or the Securities and any guarantees or security at any time held by or for the
benefit of any of them.

            Section 14.22 Severability.

            Any provision of this Article Fourteen which is prohibited or
unenforceable in any jurisdiction shall not invalidate the remaining provisions
and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction
unless its removal would substantially defeat the basic intent, spirit and
purpose of this Indenture and this Article Fourteen.

            Section 14.23 Successors and Assigns.

            Each Guarantee shall be binding upon and inure to the benefit of
each Guarantor and the Trustee and the other Guaranteed Parties and their
respective successors and permitted assigns, except that no Guarantor may assign
any of its obligations hereunder or thereunder.

                                 GUARANTEE

            We hereby confirm that:

            (i) we are an institutional "accredited investor" within the meaning
      of Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as
      amended (the "Securities Act") (an "Accredited Investor"), or a "qualified
      institutional buyer" as defined in Rule 144A under the Securities Act (a
      "QIB") purchasing Notes for the account of one or more Accredited
      Investors;

           (ii) any purchase of Notes by us will be for our own account or for
      an account with respect to which we exercise sole investment discretion
      and that we are and any such account are (a) a QIB, and aware that the
      sale is being made in reliance on Rule 144A under the Securities Act, (b)
      an Accredited Investor, or (c) a person other than a U.S. person ("foreign
      purchasers", which term shall 


                                      B-1

      include dealers or other professional fiduciaries in the United States
      acting on a discretionary basis for foreign beneficial owners (other than
      an estate or trust)) in offshore transactions meeting the requirements of
      Rule 903 or 904 of Regulation S under the Securities Act;

          (iii) we have such knowledge and experience in financial and business
      matters that we are capable of evaluating the merits and risk of
      purchasing Notes and we and any accounts for which we are acting are able
      to bear the economic risks of and an entire loss of our or their
      investment in the Notes;

           (iv) we are not acquiring Notes with a view to any distribution of
      Notes in a transaction that would violate the Securities Act or the
      securities laws of any state of the United States or any other applicable
      jurisdiction; provided that the disposition of our property and the
      property of any accounts for which we are acting as fiduciary shall remain
      at all times within our and their control;

            (v) we have had access to such financial and other information, and
      have been afforded the opportunity to ask such questions of
      representatives of the Company and receive answers thereto, as we deem
      necessary in order to evaluate our proposed investment in the Notes; and

           (vi) we acknowledge that the Notes have not been registered under the

we acquire any Notes, that, prior to (x) the date which is two years (or such
shorter period of time as permitted by Rule 144(k) under the Securities Act or
any successor provision thereunder) after the later of the date of original
issuance of the Notes and the last date on which the Company or any affiliate of
the Company was the owner of such Notes, or any predecessors thereto and (y)
such later date, if any, as may be required by applicable laws, the Notes may be
offered, resold, pledged or otherwise transferred only (a) to Multicanal or any
of its subsidiaries, (b) inside the United States to a QIB in compliance with
Rule 144A under the Securities Act,

the requirements of Rule 903 or Rule 904 of Regulation S under the Securities
Act, (e) pursuant to the exemption from registration provided by Rule 144 under

evidence satisfactory to the Company and the Trustee that the foregoing
restrictions on transfer have been complied with. We further understand that the
Notes purchased by us will be in the form of definitive physical certificates
and that such certificates will bear a legend reflecting the substance of this
paragraph. We further agree to provide to any person acquiring any of the Notes
from us a notice advising such person that transfers of such Notes are
restricted as stated herein and that certificates representing such Notes will
bear a legend to that effect.

upon the truth and accuracy of our acknowledgments, representations and
agreements set forth herein, and we agree to notify you promptly in writing if
any of our acknowledgments, representations or agreements herein cease to be
accurate and complete.

The provisions of this Section 2 are for the benefit of the holders from time to
time of Senior Indebtedness, and the Trustee on behalf of such holders, and the

            (i) The holders of Senior Indebtedness shall be entitled to receive

      other amount owing in respect of, this Deeply Subordinated Shareholder
      Indebtedness;

            (ii) until payment in full of all Senior Indebtedness, any
      distribution of assets of any kind or character in respect of this Deeply
      Subordinated Shareholder Indebtedness to which the Holder would be
      entitled but for this Section 2 shall be paid by the Relevant Obligor or
      by any receiver, trustee in bankruptcy, liquidating trustee, assignee,
      agents or other Persons making such payment or distribution to the holders
      of Senior Indebtedness, as their interests may appear; and

            (iii) in the event that, notwithstanding the foregoing, any payment
      or distribution of any assets of any kind or character in respect of this
      Deeply Subordinated Shareholder Indebtedness, shall be received by the
      Holder from the Relevant Obligor or from any receiver, trustee in
      bankruptcy, liquidating trustee, assignee, agents or other Persons making
      such payment in respect of this Deeply Subordinated Shareholder
      Indebtedness or set-off against liabilities of the Holder to the Relevant
      Obligor before all Senior Indebtedness is paid in full, such payment or
      distribution shall be held in trust for the benefit of and shall, at the
      Holder's expense, be paid over to the holders of Senior Indebtedness, as
      their interests may appear, for application to the payment of all Senior
      Indebtedness until all Senior Indebtedness shall have been paid in full
      after giving effect to any concurrent payment or distribution to the
      holders of Senior Indebtedness in respect of such Senior Indebtedness.

<PAGE>
                                      -3-


            For purposes of this Section 2, "payment in full", with respect to
Senior Indebtedness, means the receipt on an irrevocable basis of United States
Dollars in an amount equal to the unpaid principal amount of the Senior
Indebtedness and premium, if any, and interest thereon to the date of such
payment, together with all other amounts owing with respect to such Senior
Indebtedness.

the form required in a bankruptcy, reorganization, insolvency, receivership or
similar proceeding relating to the Relevant Obligor or its property prior to 45
days before the expiration of the time to file such claims then (i) upon the
request of the Trustee, the Holder shall file such claims and proofs of claim in
respect of this Deeply Subordinated Shareholder Indebtedness and execute and
deliver such powers of attorney, assignments and proofs of claim as may be
directed by the Trustee to enable it to enforce any and all claims upon or in
respect of this Deeply Subordinated Shareholder Indebtedness and to collect and
receive any and all payments or distributions which may be payable or
deliverable at any time upon or in respect of this Deeply Subordinated
Shareholder Indebtedness, and (ii) whether or not the Trustee shall take action
described in clause (i) above, the Trustee shall nevertheless be deemed to have
such powers of attorney as may be necessary to file appropriate claims and
proofs of claim and otherwise exercise the powers described above.

            (c) It is hereby agreed that any provision hereof pursuant to which
one party holds assets in trust for the benefit of the other party is not
intended to (and shall not) constitute, create or give rise to a security
interest of any kind in respect of such assets.

            (d) If for any reason a trust in favor of, or a holding of property
for, the holders of Senior Indebtedness or the Trustee is invalid or
unenforceable, the Holder will pay and deliver to the holders of Senior
Indebtedness or the Trustee (as the case may be) for application in accordance
with paragraph (a)(iii) above an amount equal to the payment, receipt or
recovery in cash or in kind which it would otherwise have been bound to hold in

corporated ("Merrill Lynch") and Bear Stearns & Co. Inc. and Goldman, Sachs &
Co. (collectively with Merrill Lynch, the "Initial Purchasers") with respect to
the issue and sale by the Issuers and the purchase by the Initial Purchasers,
acting severally and not jointly, of the respective numbers set forth in
Schedule A of an aggregate of 125,000 Units (the "Units") consisting of
US$125,000,000 aggregate principal amount of 13 1/2% Senior Notes due 2005 of
the Company (the "Notes") and an aggregate of 125,000 Non-Voting Class B Member
Interests (the "Holding Shares") of the LLC. Each Unit will consist of US$1,000
principal amount of Notes and one Holding Share. The Units will be issued under
an agreement (the "Unit Agreement") to be dated as of June 6, 1997 among the
Company, the LLC and The Chase Manhattan Bank, as unit agent (the "Unit Agent").
The Notes are to be issued pursuant to an indenture to be dated as of June 1,
1997 (the "Indenture") between the Company, as issuer of the Notes, and The
Chase Manhattan Bank, as trustee (the "Trustee"). Each of the Trustee and Chase
Trust Bank (the "Principal Paying Agent") will act as a co-paying agent with
respect to the Notes under the Indenture. Pursuant to an agreement (which will
contain customary representations as to, among other things, good title, valid
delivery and lack of claims or encumbrances on such common stock) between the
Company and the LLC to be dated June 6, 1997 (the "Company-LLC Subscription
Agreement"), 125,000 shares of common stock (acoes ordinarias), with no par
value, of the Company (the "Common Stock") representing in the aggregate
approximately 7.0% of the common share capital of the Company, will be issued
and delivered by the Company to the LLC for the capital accounts of the holders
of Holding Shares issued as a part of the Units. The Holding Shares have been
authorized and, at the Closing Time (as defined herein) will be issued in
accordance with the terms of the agreement substantially in the form of Exhibit
C hereto dated as of June 6, 1997 (the "LLC Agreement") among the members from
time to time of the LLC.

            Approximately US$46,000,000 of the net proceeds from the sale of the
Units (the "Initial Escrow Amount"), representing funds that, together with the
proceeds from the investment thereof, are intended to be sufficient to pay the
first six in-

terest payments on the Notes, is to be placed in a collateral account in the
United States and pledged to the Trustee, for the benefit of the holders of the
Notes and the Trustee (in its capacity as such under the Indenture) pursuant to
the Escrow Agreement, dated as of June 6, 1997 (the "Escrow Agreement") among
the Company, Chase Manhattan Bank, as Escrow Agent (the "Escrow Agent"), and the
Trustee.

            Unless the context otherwise requires, the term "Securities" refers
collectively to the Notes, the Holding Shares and the Units. This agreement
(this "Agreement" or the "Purchase Agreement"), the Unit Agreement, the
Indenture, the Securities, the Exchange Notes (as defined below), the Private
Exchange Notes (as defined below), the Escrow Agreement, the agreement with CT
Corporation System referred to in Section 18 hereof (the "Agency Agreement"),
the Notes Registration Rights Agreement (as defined below), the LLC Agreement,
the Company-LLC Subscription Agreement and the Equity Registration Rights
Agreement (as defined below) are referred to collectively as the "Operative
Documents."

            The Securities will be offered and sold to the Initial Purchasers
without registration under the Securities Act of 1933, as amended (the "Act"),
in reliance upon an exemption from the registration requirements of the Act. The
Issuers have prepared and delivered to each Initial Purchaser copies of
preliminary offering memoranda dated March 16, 1997 (the "March Preliminary
Offering Memorandum") and May 16, 1997 (the "May Preliminary Offering Memorandum
and, together with the March Preliminary Offering Memorandum, the "Preliminary
Offering Memorandum") and have prepared and will deliver to each Initial
Purchaser copies of a final offering memorandum dated May 30, 1997 (the "Final
Offering Memorandum"), each to be used by such Initial Purchaser in connection
with its solicitation of purchases of, or offering of, the Securities. "Offering

Agreement, the most recent offering memorandum (whether the Preliminary Offering
Memorandum or the Final Offering Memorandum, together with any amendment or
supplement to either such document), which has been prepared and delivered by

purchases of, or offering of, the Securities. The Issuers hereby confirm that
the use of the Offering Memorandum in connection with the offer and resale of
the Securities by the Initial Purchasers in accordance with the terms hereof is
authorized by each of them. If the Issuers prepare a supplement dated the date
hereof to the Preliminary Offering Memorandum containing only pricing related
information, then the term "Offering Memorandum" for purposes of this Agreement
shall refer collectively to the Preliminary Offering Memorandum and such
supplement.

            All references in this Agreement to financial statements and
schedules and other information which is "contained," "included" or "stated" in
the Offering Memorandum (or other references of like import) shall be deemed to
mean and include all such financial statements and schedules in the Offering
Memorandum.

            The Issuers understand that the Initial Purchasers propose to make
an offering (the "Offering") of the Securities only on the terms and in the
manner set forth herein to purchasers ("Subsequent Purchasers"), as soon as the
Initial Purchasers deem advisable after this Agreement has been executed and
delivered. The Offering will be made only (i) to persons in the United States
whom the Initial Purchasers reasonably believe to be qualified institutional
buyers ("Qualified Institutional Buyers") as defined in Rule 144A under the Act,
as such rule may be amended from time to time ("Rule 144A"), in transactions
under Rule 144A, (ii) to a limited number of other institutional "accredited
investors" (as defined in Rule 501(a)(1), (2), (3) and (7) under Regulation D of
the Act ("Accredited Investors")) in private sales exempt from registration
under the Act and/or (iii) to non-U.S. persons outside the United States to whom
the Initial Purchasers reasonably believe offers and sales of the Securities may
be made in reliance upon Regulation S under the Act ("Regulation S"), in
transactions meeting the requirements of Regulation S.

            The Initial Purchasers and other holders of Securities (including
subsequent transferees) will be entitled to the

"Shareholders") and Chase Mellon Shareholder Services, as transfer agent (the
"Holding Share Transfer Agent"), in the form attached hereto as Exhibit B.

circumstances set forth therein either (i) a registration statement under the
Act registering the Exchange Notes (as defined in the Notes Registration Rights
Agreement) to be offered in exchange for the Notes and to use its best efforts

      circumstances under which they were made, not misleading; provided,
      however, that the Issuers make no representations or warranties as to any
      information contained in or omitted from the Offering Memorandum, or any

      operations, business affairs or business prospects of the Issuers taken as
      a whole or (ii) the ability of any of the Issuers to duly and punctually

      justify the variation, suspension, cancellation or termination of any such
      authorizations or licenses held or controlled by the Company with respect
      to the construction or operation of its businesses, which variation,
      suspension, cancellation or termination could be reasonably expected to

      the Collateral.

            (x) Each the Issuers has all requisite power and authority to
      execute, issue and deliver the Unit Agreement and to incur and perform all

      Offering Memorandum. Each Shareholder Commitment has been duly authorized,
      executed and delivered by the Company, to the Company's knowledge, by each
      other party thereto and constitutes the valid and binding obligations of
      each party thereto. The Shareholder Commitments, taken together, are

            (xx) The Company has the authorized, issued and outstanding
      capitalization set forth in the Offering Memorandum under the subheading
      "Actual" under the caption "Capitalization" (except that 8,700 additional

      issued); all of the outstanding capital stock of the Company has been duly
      authorized and validly issued, is fully paid and nonassessable and was not
      issued in violation of any preemptive or similar rights (whether provided
      contractually or pursuant to any Organizational Document). No holder of
      any securities of either of the Issuers is entitled to (x) have such
      securities (other than the Notes, the Exchange Notes and the Private
      Exchange Notes, if any) registered under any registration statement

      personal liability by reason of being such a holder; the Common Stock is
      not subject to preemptive or similar rights, except to the extent set

      Organizational Documents, ownership of the Common Stock of the Company is

      and no certificates with respect to such shares of capital stock exist;
      the Common Stock conforms to all 
<PAGE>
                                      -17-


      statements relating thereto in the Offering Memorandum and such

      qualifications, limitations and restrictions in respect of the Class B
      Member Interests are valid, binding, and enforceable in accordance with
      the terms of the LLC Agreement under Delaware law. There are no
      outstanding or authorized options, warrants, purchase rights, conversion
      rights, exchange rights or other contracts or commitments or preemptive
      rights that could require the LLC to issue, sell or otherwise cause to
      become outstanding any member interests of the LLC or any other security,
      and there are no outstanding securities convertible into such member
      interests of the LLC or any other security.

      authority, agency or other body, other than, in the case of clauses (B)
      and (C), such defaults or violations which, individually or in the

      Material Adverse Effect.

            (xxiii) The Company owns or possesses, or can acquire on reasonable
      terms, adequate licenses, trademarks, service marks, trade names,
      copyrights and know-how (including trade secrets and other proprietary or

      "intellectual property") necessary to conduct the business now or proposed
      to be operated by each of them as described in the Offering Memorandum,
      except where the failure to own, possess or have the ability to acquire
      any such intellectual property could not, individually or in the
      aggregate, be reasonably expected to have a Material Adverse Effect; and,

      Offering Memorandum, no officers or directors of the Company has received
      any notice of infringement of or conflict with (and the Company does not

      others with respect to any of such intellectual property which, if any
      such assertions of infringement or conflict were sustained, individually

      their respective businesses in the manner described in the Offering
      Memorandum, except to the extent that the failure to so obtain or file,

      or result in a Material Adverse Effect.

            (xxv) There is no legal action, suit, proceeding inquiry or
      investigation before or by any court or governmental body or agency,
      domestic or foreign, now pending or, to the knowledge of the Issuers,

      be, (a) has established appropriate U.S. GAAP reserves for, and (b) is
      contesting in good faith, the payment of, such taxes; and there is no tax

      Amounts (as defined in the Indenture) as may be necessary in order that
      the amounts received by the holder of any Note, Exchange Note or Private

      subdivision or taxing authority thereof or therein.

      each case, as described in the Offering Memorandum or to the extent the
      failure to have such title or the existence of such liens, charges,
      encumbrances or restrictions does not result in a Material Adverse Effect.

      a company "controlled by" an "investment company" as such terms are
      defined in the Investment Com-

<PAGE>
                                      -26-


States to whom the Initial Purchasers reasonably believe offers and sales of the
Securities may be made in reliance upon Regulation S under the Act in
transactions meeting the requirements of Regulation S; provided that with
respect to clause (B), each such transfer of Securities is effected by the
delivery to such purchaser of Securities in definitive form and registered in
its name (or its nominee's name) on the books maintained by the Unit Agent; and
provided, further, that with respect to clause (B), such institutional investors
shall be required to complete and deliver an Accredited Institutional Investor

            SECTION 5. Covenants of the Issuers. Each of the Issuers covenant
with the Initial Purchasers as follows:

            (a) Each of the Issuers will use its reasonable best efforts to
      obtain on or prior to the Closing Time all government authorizations
      (including, but not limited to, the Prior Authorization and any other
      necessary authorizations from the Brazilian Central Bank) required in
      connection with the issue and sale of the Units, the Notes, the Exchange
      Notes, the Private Exchange Notes, the Common Stock delivered to the LLC
      pursuant to the Company-LLC Subscription Agreement or the Holding Shares
      and the performance of their respective obligations thereunder and under
      this Agreement, the Notes Registration Rights Agreement, the Indenture,
      the Escrow Agreement, the Units, the Notes, the Agency Agreement, the LLC
      Agreement, the Company-LLC Subscription Agreement and the Equity
      Registration Rights Agreement, and to cause such authorizations to be
      continued in effect so long as any of the Units, the Notes, the Exchange
      Notes, the Private Exchange Notes, if any, or the Holding Shares remain
      outstanding.

            (b) The Issuers will promptly, and in any event not more than 10
      days after the Closing Time, (i) make application to the Brazilian Central
      Bank for the Registration Certificate and thereafter do all things
      reasonably necessary to obtain the Registration Certificate and provide
<PAGE>
                                      -27-


      evidence thereof to the Initial Purchasers and (ii) do all things
      reasonably necessary to obtain the issuance of the Registration
      Certificate by the Brazilian Central Bank, as soon as practicable after
      such approval is necessitated, to make any payment in dollars not set
      forth in the Registration Certificate or to make any payment provided for
      therein earlier than its originally scheduled date for payment.

            (c) The Issuers will pay such additional amounts as may be necessary
      in order that the net amounts receivable by the Initial Purchasers
      pursuant to this Agreement after any withholding or deduction for or on
      account of any present or future taxes, duties, assessments or other
      governmental charges of whatever nature imposed or levied by or on behalf
      of Brazil or Japan or any political subdivision thereof or by any
      authority therein or thereof having power to tax shall equal the
      respective amounts which would have been receivable in the absence of such
      withholding or deduction.

            (d) The Issuers will furnish to the Initial Purchasers and counsel
      for the Initial Purchasers, without charge, such number of copies of the
      Preliminary Offering Memorandum and the Offering Memorandum and any
      amendments or supplements thereto as the Initial Purchasers and their
      counsel may reasonably request.

            (e) The Issuers will not at any time make any amendment or
      supplement to the Preliminary Offering Memorandum or the Offering
      Memorandum without the prior written consent of the Initial Purchasers,
      which consent shall not be unreasonably withheld or delayed; provided,
      however, that the consent of the Initial Purchasers shall not be required
      if in the judgment of the Issuers upon advice of U.S. counsel to the
      Issuers any such amendment or supplement is necessary so as to make the
      statements contained in the Offering Memorandum not misleading.

            (f) If at any time prior to completion of the distribution of the
      Securities by the Initial Purchasers to 
<PAGE>
                                      -28-


      purchasers who are not its affiliates (as determined by the Initial
      Purchasers) any event shall occur or condition shall exist as a result of
      which it is necessary, in the reasonable opinion of the Initial Purchasers
      or counsel for the Initial Purchasers, to amend or supplement the Offering
      Memorandum in order that the Offering Memorandum, as then amended or
      supplemented, will not include an untrue statement of a material fact or
      omit to state a material fact necessary in order to make the statements
      therein, in the light of the circumstances existing at the time it is
      delivered to a purchaser, not misleading or if in the reasonable opinion
      of the Initial Purchasers or counsel to the Initial Purchasers, such
      amendment or supplement is necessary to comply with applicable law, the
      Issuers will, subject to paragraph (e) of this Section 5, promptly
      prepare, at their own expense, such amendment or supplement as may be
      necessary to correct such untrue statement or omission or to effect such
      compliance (in form and substance agreed upon by the Initial Purchasers
      and counsel to the Initial Purchasers), so that as so amended or
      supplemented, the statements in the Offering Memorandum will not include
      an untrue statement of a material fact or omit to state a material fact
      necessary in order to make the statements therein, in the light of the
      circumstances existing at the time it is delivered to a purchaser, not
      misleading or so that such Offering Memorandum as so amended or
      supplemented will comply with applicable law, as the case may be, and
      furnish to the Initial Purchasers such number of copies of such amendment
      or supplement as the Initial Purchasers may reasonably request. Each of
      the Issuers agrees to notify the Initial Purchasers in writing to suspend
      use of the Offering Memorandum as promptly as practicable after the
      occurrence of an event specified in this paragraph (f) of which it has
      knowledge, and the Initial Purchasers hereby agree upon receipt of such
      notice from the Issuers to suspend use of the Offering Memorandum until
      the Issuers have amended or supplemented the Offering Memorandum to
      correct such misstatement or omission or to effect such compliance.

            (g) Notwithstanding any provision of paragraph (d) or (e) to the
      contrary, however, the Issuers' obligations under paragraphs (d) and (e)
      and the Initial Purchasers' obligations under paragraph (f) shall
      terminate on the date upon which no Initial Purchaser nor any of their
      respective affiliates continues to hold Securities acquired as part of
      their initial distribution.

            (h) None of the Issuers nor any of their affiliates (as defined in
      Rule 501(b) under the Act) will solicit any offer to buy or offer or sell
      the Units, the Notes, the Exchange Notes or the Private Exchange Notes, if
      any, or the Holding Shares by means of any form of general solicitation or
      general advertising (as such terms are used in Regulation D under the
      Act), or by means of any directed selling efforts (as defined in Rule 902
      under the Act) in the United States in connection with the Securities
      being offered and sold pursuant to Regulation S or in any manner involving
      a public offering within the meaning of Section 4(2) of the Act prior to
      the effectiveness of a registration statement with respect to the Units,
      the Notes, the Exchange Notes or the Private Exchange Notes or the Holding
      Shares, as applicable.

            (i) None of the Issuers nor any of their affiliates (as defined in
      Rule 501(b) under the Act) will offer, sell or solicit offers to buy or
      otherwise negotiate in respect of any security (as defined in the Act)
      which could be integrated with the sale of the Securities in a manner that
      would require the registration of any of the Securities under the Act.

            (j) The Company will, so long as any Notes, Exchange Notes, Private
      Exchange Notes or Holding Shares are outstanding, furnish to the Initial
      Purchasers, the Trustee, the Holding Share Transfer Agent and each holder
      of any Notes, Exchange Notes, Private Exchange Notes or Holding Shares on
      a timely basis, whether or not the Company has a class of securities
      registered under the Exchange Act, (i) within 140 days after the end of
      each fiscal year, annual reports on Form 20-F (or any successor form) 
      contain-

<PAGE>
                                      -30-


      ing the information required to be contained therein (or required
      in such successor form); (ii) within 60 days after the end of each of the
      first three fiscal quarters of each fiscal year reports on Form 6-K (or
      any successor form) containing substantially the same information required
      to be contained in Form 10-Q (or required in any successor form); and
      (iii) promptly from time to time after the occurrence of an event required
      to be therein reported, such other reports on Form 6-K (or any successor
      form) containing substantially the same information required to be
      contained in Form 8-K (or required in any successor form). Notwithstanding
      the foregoing, prior to the filing of the Exchange Offer Registration
      Statement with the SEC and in the event that the Company never becomes
      subject to the reporting requirements of Section 13 or 15(d) of the
      Exchange Act, the Company will file with the Trustee and provide the
      Initial Purchasers and the holders of any of the Securities and
      prospective purchasers of any of the Securities designated by such
      holders, upon request of such holders or prospective purchasers, all of
      the information that would have been required to have been filed with the
      SEC pursuant to clauses (i), (ii) and (iii) above. In addition to the
      above, the Company and the LLC will make available any further information
      required to be delivered pursuant to Rule 144A(d)(4) under the Act to
      permit compliance with Rule 144A in connection with resales of any of the
      Securities. Each of the reports will be prepared in accordance with U.S.
      GAAP consistently applied and will be prepared in accordance with the
      applicable rules and regulations of the SEC.

            (k) Each of the Issuers will use its reasonable best efforts in
      cooperation with the Initial Purchasers to (i) permit the Units, the Notes
      and the Holding Shares to be eligible for clearance and settlement through
      The Depository Trust Company, the Euroclear System and Cedel Bank, societe
      anonyme, and (ii) permit the Securities to be designated as PORTAL
      securities in accordance with the rules and regulations of the NASD.

            (l) Each Note, Private Exchange Note, if any, and each Holding Share
      will bear the following legend until such legend shall no longer be
      necessary or advisable because the applicable Security is no longer
      subject to the restrictions on transfer described herein:

                  THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER
            THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
            ANY STATE OR OTHER SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY
            INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED,
            TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE
            ABSENCE OF SUCH REGISTRATION OR UNLESS THE TRANSACTION IS EXEMPT
            FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE

            (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
            DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS AN
            INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1),

            TERMINATION DATE"), OFFER, SELL OR OTHERWISE TRANSFER THIS SECURITY
            EXCEPT (A) TO THE ISSUER OR ANY SUBSIDIARY THEREOF, (B) PURSUANT TO

            SECURITIES ACT, (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR
            RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS
            A "QUALIFIED INSTITUTIONAL BUYER" AS DEFINED IN RULE 144A UNDER THE
            SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT

            THAT IS ACQUIRING THE SECURITIES FOR ITS OWN ACCOUNT, OR FOR THE
            ACCOUNT OF SUCH ACCREDITED INVESTOR, FOR INVESTMENT PURPOSES AND NOT
            WITH A VIEW TO, OR FOR OFFER OR SALE IN CONNECTION WITH, ANY

            TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE
            EFFECT OF THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON THE REQUEST
            OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE. AS USED
            HEREIN, THE TERMS "OFFSHORE TRANSACTION," "UNITED STATES" AND "US
            PERSON" HAVE THE RESPECTIVE MEANINGS GIVEN TO THEM BY REGULATION S
            UNDER THE SECURITIES ACT.

            (m) The Issuers will arrange for the registration and qualification
      of the Securities for offering and sale under the applicable securities or
      "blue sky" laws of such states and other jurisdictions as the Initial
      Purchasers may designate in connection with the resale of the Securities
      as contemplated by this Agreement and the Offering Memorandum and will
      continue such qualifications in effect for as long as may be necessary to
      complete the distribution of the Securities; provided that in no event
      shall the Issuers be obligated to (i) qualify as a foreign corporation or
      as a dealer in securities in any jurisdiction where it would not otherwise
      be required to so qualify but for this Section 5(m), (ii) file any general
      consent to service of process in any jurisdiction where it is not at the
      Closing Time then so subject or (iii) subject itself to taxation in any
      such jurisdiction if it is not so subject. The Issuers will file such
      statements and reports as may be required by the laws of each jurisdiction
      in which the Securities have been qualified as above provided. The Issuers
      shall promptly advise the Initial Purchasers of the receipt by any of the
      Issuers of any notification with respect to the suspension of the
      qualification or exemption from qualification of the Securities for
      offering or sale in any jurisdiction or the institution, threatening or
      contemplation of any proceeding for such purpose.

            (n) From the date hereof to the Closing Time, none of the Issuers
      will issue any press release or other public communication directly or
      indirectly or hold any press conference with respect to the Issuers or the
      business, financial condition, assets, results of operations or prospects
      of the Issuers, without the prior consent of the Initial Purchasers,
      unless in the judgment of the Issuers and their counsel, and after
      notification to the Initial Purchasers, such press release, communication
      or conference is required by law.

            (o) The Company will use the proceeds received from the sale of the
      Securities in the manner specified in the Offering Memorandum under the
      heading "Use of Proceeds."

            (p) Pursuant to the Escrow Agreement, the Company will deposit the
      Initial Escrow Amount into a collateral account in the United States,
      representing funds that together with the proceeds from the investment
      thereof will be sufficient to pay the first six interest payments on the
      Notes, and will take all actions necessary to pledge, assign and set over
      to the Trustee, for the benefit of the holders of the Notes and the
      Trustee (in its capacity as such under the Indenture), and irrevocably
      grant to the Trustee for the benefit of the holders of the Notes and the

consummated because any condition to the obligations of the Initial Purchasers

terminated pursuant to Section 11 hereof or because of any failure, refusal or
inability on the part of any of the Issuers to perform all obligations and
satisfy all conditions on their part to be performed or satisfied hereunder

            required under the securities or Blue Sky laws of certain
            jurisdictions, as to which we express no opinion) nor will such
            issuance, sale and delivery of the Securities to the Initial
            Purchasers or the execution, delivery and performance of such
            instruments and agreements by the Company and the LLC, as
            applicable, conflict with, or result in a violation of any of the
            terms or provisions of, any existing applicable United States
            Federal or New York State judgment, order or decree which is known
            to such counsel or any

            governmental instrumentality or court located in the United States
            having jurisdiction over the Company or any of its properties or
            assets, except that (a) the transactions contemplated by the Notes

            therein, to the registration and other requirements of the Act and
            the Trust Indenture Act of 1939, as amended (the "Trust Indenture

            Registration Rights Agreement are subject, to the extent set forth
            therein, to the registration requirements of the Act;

            action, suit, proceeding, inquiry or investigation to which the
            Company or the LLC is a party, or to which the property of the
            Company or the LLC is subject, before or brought by any court or
            governmental agency or body in the Federal courts of the United
            States or in any State court in the State of New York, which might
            reasonably be expected to have or result in a Material Adverse
            Effect, or which might reasonably be expected to materially and
            adversely affect the properties or assets thereof or the
            consummation or performance by the Company or the LLC of its

            Documents, the issuance by the Company of the Notes, the issuance by
            the LLC of the Holding Shares and the consummation of the
            transactions contemplated in the Operative Documents and compliance
            by the Company and the LLC with their respective obligations under
            the Operative Documents will not, whether with or without the giving
            of notice or lapse of time or both, (a) conflict with or constitute
            a breach of, or a default or otherwise cause or permit any holder of
            indebtedness of the Company to have a

            such indebtedness of the Company or the LLC under or (b) result in
            the creation or imposition of any lien (other than liens
            contemplated by the Escrow Agreement), charge or encumbrance upon
            any property or assets of the Company or the LLC pursuant to any
            material contract, indenture, mortgage, deed of trust, loan or

            known to us, to which the Company or the LLC is a party or by which
            either of them may be bound, or to which any of the property or
            assets of the Company or the LLC is subject, or (c) result in any
            violation of the provisions of the LLC Agreement, or any applicable
            New York or Federal law, statute, rule, regulation, judgment, order,
            writ or decree, known to us, of any government, government
            instrumentality or court having jurisdiction over the Company or the
            LLC or any of their respective properties, assets or operations
            except in the case of (a), (b), or (c) above, such as would not,
            either singly or in the aggregate, have a Material Adverse Effect;

            and assuming that (a) the Company has been duly organized and is
            validly existing and in good standing under the laws of the

            Agency Agreement, the Notes Registration Rights Agreement, the
            Equity Registration Rights Agreement and the Company-LLC
            Subscription Agreement and to perform its obligations thereunder and

            all requisite corporate action by the Company, (e) the Unit
            Agreement, the Indenture, the Escrow Agreement, the Agency
            Agreement, the Notes Registration Rights Agreement, the Equity
            Registration Rights Agreement and the Company-LLC Subscription
            Agreement have been duly executed and delivered by the Company, (f)
            the LLC has all requisite limited liability power and authority to

            Agreement and the Equity Registration Rights Agreement and to

            with the provisions of the Indenture (assuming the due
            authorization, execution and delivery of the Indenture by the
            Trustee) and delivered and paid for in accordance with the terms of
            this Agreement, registered holders of the Notes will be entitled to
            the benefits of the Indenture and the Indenture will constitute the

            against the Company in accordance with their terms, and (III) each
            of the Unit Agreement, the Indenture, the Escrow Agreement, the
            Agency Agreement, the Notes Registration Rights Agreement, the

            Subscription Agreement constitutes a valid and binding agreement of
            the Company, enforceable against the Company in accordance with its
            terms, and (IV) each of the Unit Agreement, the Company-LLC
            Subscription Agreement and the Equity Registration Rights Agreement
            constitutes a valid and binding obligation of the LLC, enforceable
            against the LLC in accordance with its terms, except, in each case,
            (x) as the enforceability thereof may be limited by bankruptcy,
            insolvency, reorganization, fraudulent conveyance, moratorium or
            similar laws affecting the rights and remedies of creditors
            generally and (y) such counsel need express no opinion concerning
            the enforceability of, or the enforceability under law under certain
            circumstances of, the indemnification provisions of Section 4 of the
            Notes Registration Rights Agreement or Section 5 of the Equity
            Registration Rights Agreement with respect to a liability where such
            indemnification is contrary to public policy;

                  (5) assuming compliance by the Escrow Agent with the terms of
            the Escrow Agreement, the Escrow Agreement creates a valid perfected
            security interest in favor of the Trustee in all right, title and
            interest of the Company in and to the Escrow Account and the
            Collateral;

                  (6) the statements in the Offering Memorandum under the
            headings "Summary -- The Offering," "Description of the Units,"
            "Description of the Notes," "Exchange Offer; Notes Registration
            Rights" and "Equity Registration and Other Rights," insofar as such
            statements purport to summarize certain provisions of the Units, the
            Notes, the Exchange Notes, the Private Exchange Notes, the
            Indenture, the Notes Registration 
<PAGE>
                                      -42-


            Rights Agreement and the Equity Registration Rights Agreement,
            provide a fair summary of such provisions of such agreements and
            instruments;

                  (7) assuming the Securities are issued and sold under the
            circumstances contemplated by this Agreement and the representations
            and warranties of the Issuers and the Initial Purchasers set forth
            herein are true and correct, it is not necessary in connection with
            the offer, sale and delivery of the Securities to the Initial
            Purchasers and to each Subsequent Purchaser in the manner
            contemplated by the Purchase Agreement and the Offering Memorandum
            to register the Securities under the 1933 Act or to qualify the
            Indenture under the Trust Indenture Act;

                  (8) assuming the Company invests the net proceeds of the
            Offering as described under "Use of Proceeds" in the Final Offering
            Memorandum, neither the Company nor the LLC is an "investment
            company" or an entity "controlled" by an "investment company," as
            such terms are defined in the Investment Company Act of 1940 (the
            "Investment Company Act") nor is the Company or the LLC otherwise
            subject to regulation or registration under the Investment Company
            Act. In forming the foregoing opinion, we are not relying on the
            availability of any exemption under Section 3(c)(1) or 3(c)(7) of
            the Investment Company Act;

                  (9) the statements in the Offering Memorandum under the
            caption "Tax Considerations -- United States" fairly summarize the
            material United States Federal tax consequences of acquiring, owning
            and disposing of the Units, the Notes, the Exchange Notes and the
            Holding Shares;

                  (10) the LLC will be treated for federal income tax purposes
            as a partnership and, based on the manner in which it intends to
            limit its business activities and monitor its "qualifying income"
            for purposes of Section 7704(c) of the Internal Revenue Code of
<PAGE>
                                      -43-


            1986, as amended (the "Code"), it will not be classified as a
            publicly traded partnership that is treated as a corporation under
            section 7704(a) of the Code.

            In addition such counsel shall state that such counsel has
      participated in conferences with representatives of the Initial
      Purchasers, officers and other representatives of the Issuers and
      representatives of the independent certified accountants of the Issuers,
      at which conferences the contents of the Offering Memorandum and related
      matters were discussed, and although such counsel has not verified and
      does not pass upon or assume any responsibility for the accuracy,
      completeness or fairness of the statements contained in the Offering
      Memorandum (except and only to the extent set forth in subclauses (7) and
      (10) above), on the basis of the foregoing (relying as to materiality to
      the extent such counsel deems appropriate upon opinions of officers and
      other representatives of the Issuers), on the basis of the foregoing
      nothing has come to its attention to cause it to believe that the Offering
      Memorandum at the date thereof or as of the Closing Time, contained or
      contains an untrue statement of a material fact or omitted or omits to
      state a material fact necessary to make the statements therein, in the
      light of the circumstances under which they were made, not misleading (it
      being understood that such counsel has not been requested to and does not
      make any comment with respect to (i) the financial statements, and the
      notes thereto and related schedules, (ii) other financial or statistical
      data found in or derivable from the financial, accounting or internal
      records of the Issuers or (iii) any forward-looking or projected financial
      or statistical data relating to the Issuers, in each case, included in the
      Offering Memorandum).

            In rendering such opinion, such counsel (A) need not express any
      opinion with regard to the application of laws of any jurisdiction other
      than the Federal laws of the United States and the laws of the State of
      New York and (B) may rely as to matters of fact (but not as to legal
<PAGE>
                                      -44-


      conclusions), to the extent they deem proper, on certificates of
      responsible officers of the Issuers and public officials. Such opinion
      shall not state that it is to be governed or qualified by, or that it is
      otherwise subject to, any treatise, written policy or other document
      relating to legal opinions, including, without limitation, the Legal
      Opinion Accord of the ABA Section of Business Law (1991).

            References to the Offering Memorandum in this Section (a) include
      any supplement thereto prior to the Closing Time.

            (b) At the Closing Time, the Initial Purchasers shall have received
      the opinion of Xavier, Bernardes, Braganca, Brazilian counsel to the
      Issuers, dated as of the Closing Time, in form and substance satisfactory
      to the Initial Purchasers and counsel for the Initial Purchaser, to the
      effect that:

            existing sociedade anonima in good standing under the laws of the

            authority to own, lease and operate its assets and properties and
            conduct its business currently conducted and as described in the
            Offering Memorandum;

                  (2) the authorized, issued and outstanding capital stock of
            the Company is as set forth in the Offering Memorandum under the
            subheading "Actual" under the caption "Capitalization" (except that
            8,700 additional shares of the Company's redeemable preferred stock
            were subsequently issued); the Company does not have any
            subsidiaries;

                  (3) (a) the Company has the requisite corporate power and
            authority to issue, sell and deliver the Notes pursuant to the
            Purchase Agreement and the issuance, sale and delivery of the Notes

            all requisite corporate action by the Company; (b) the Company has
            all requisite corporate power and authority to issue and deliver the
            Exchange Notes and the Private Exchange Notes in exchange for the

      assume any responsibility for the accuracy, completeness or fairness of
      the statements contained in the Offering Memorandum (except and only to

      to the extent such counsel deems appropriate upon opinions of officers and
      other representatives of the Issuers), no facts have come to the attention
      of such counsel which lead such counsel to believe that the Offering
      Memorandum at the date thereof or as of the Closing Time, contained or
      contains an untrue statement of a material fact or omitted or omits to
      state a material fact necessary to make the statements therein, in the
      light of the circumstances under which they were made, not misleading; (it
      being understood that such counsel has not been requested to and does not
      make any comment with respect to (i) the financial statements, and the

      involving the application of the Federal laws of the United States or the

      the Initial Purchasers at the Closing Time and shall be satisfactory in
      form and substance to counsel for the Initial Purchasers) and (B) as to
      matters of fact (but not as to legal conclusions), to the extent they deem

      officials. Such opinion shall not state that it is to be governed or
      qualified by, or that it is otherwise subject to, any treatise, written
      policy or other document relating to legal opinions, including, without
      limitation, the Legal Opinion Accord of the ABA Section of Business Law
      (1991).

            Rights Agreement and to issue and deliver the Holding Shares

            its governance as set forth in the LLC Agreement and the LLC
            Agreement is valid and in full force and effect in the form attached
            to the Purchase Agreement as Exhibit D.

            attaches to the holders of the Class A Shares or the Class B Shares
            by virtue of their ownership thereof. The Class A Shares and the
            Class B Shares have not been issued in violation of any preemptive
            or similar right arising under the LLC Agreement or Delaware law.
            The Holding Shares have the designations, powers, preferences,
            rights, qualification, limitations and restrictions set forth in the
            LLC Agreement.

            Purchasers from the LLC have been duly authorized for issuance and
            sale to the Initial Purchasers pursuant to the Purchase Agreement,
            and when issued and delivered by the LLC pursuant to the Purchase
            Agreement, will be validly issued, fully paid and non-assessable and
            no holder of the Holding Shares is or will be subject to personal
            liability by reason of being such a Holder.

                  (5) All action on the part of LLC and its members necessary
            for the authorization, execution, delivery and performance of the
            Purchase Agreement, the Unit Agreement, the Company-LLC Subscription
            Agreement and the Equity Registration Rights Agreement and each of
            such agreements has been executed and delivered and is a valid and
            legally binding obligation of the LLC (assuming due authorization,
            execution and delivery by each of the other parties thereto).

                  (6) The statements in the Offering Memorandum under the
            heading "Description of the Class B Holding Shares," insofar as such
            statements purport to summarize certain provisions of the Class B
            Holding Shares, the Class A Holding Shares and the LLC Agreement,
            provide a fair summary of such provisions of such instruments and
            agreement.

                  (7) All consents, approvals, orders or authorizations of, or
            registrations or qualifications, designations, declarations or
            filings with any authority in the State of Delaware on the part of

            force and effect.

                  (8) Under Delaware law as currently in effect, holders of
            Holding Shares are not and will not be required to pay any tax,
            levy, impost or fee to, or register or file any document with, any
            governmental

            their ownership of member interests in the LLC.

            In rendering such opinion, such counsel may rely (A) as to matters

      laws of the State of New York, upon the opinion of Willkie Farr &
      Gallagher, United States counsel to the Issuers, and as to matters
      involving the application of the laws of the Federative Republic of
      Brazil, upon the opinion of Xavier, Bernardes, Braganca, Brazilian counsel

      Purchasers and shall be dated and furnished to the Initial Purchasers at
      the Closing Time and shall be satisfactory in form and substance to
      counsel for the Initial Purchasers) and (B) as to matters of fact (but not
      as to legal conclusions), to the extent they deem proper, on certificates
      of responsible officers of the Issuers and public officials. Such opinion
      shall not state that it is to be governed or qualified by, or that it is
      otherwise subject to, any treatise, written policy or other document
      relating to legal opinions, including, without limitation, the Legal
      Opinion Accord of the ABA Section of Business Law (1991).

            References to the Offering Memorandum in this subsection (c) include
      any supplement thereto prior to the Closing Time.

            (d) The Initial Purchasers shall have received the favorable
      opinion, dated as of the Closing Time, of Cahill Gordon & Reindel, counsel
      for the Initial Purchasers, with respect to certain matters set forth in
      subsection (a) of this Section 7.

            In rendering such opinions, such counsel (A) need not express any
      opinion with regard to the application of laws of any jurisdiction other
      than the Federal laws of the United States and the laws of the State of
      New York and (B) may rely, as to matters of fact, to the extent they deem
      proper on representations or certificates of respon-

      does not pass upon and does not assume any responsibility for the
      accuracy, completeness or fairness of the statements contained in the
      Offering Memorandum, on the basis of the foregoing (relying as to
      materiality to the extent such counsel deems appropriate upon opinions of
      officers and other representatives of the Issuers), no facts have come to
      the attention of such counsel which lead such counsel to believe that the
      Offering Memorandum, at the date thereof or as of the Closing Time,
      contained or contains an untrue statement of a material fact or omitted to
      state a material fact necessary to make the statements therein, in the
      light of the circumstances under which they were made, not misleading (it
      being understood that such counsel has not been requested to and does not
      make any comment with respect to (i) the financial statements, and the
      notes thereto and related schedules, (ii) other financial or statistical
      data found in or derivable from the financial, accounting or internal
      records of the Issuers and (iii) any forward-looking or projected
      financial or statistical data relating to the Issuers, in each case,
      included in the Offering Memorandum).

            In rendering such opinions, such counsel (A) need not express any
      opinion with regard to the application of laws of any jurisdiction other
      than the laws of the Federative Republic of Brazil and of the political
      subdivisions thereof and (B) may rely, as to matters of fact, to the
      extent they deem proper on representations or certificates of responsible
      officers of the Issuers and certificates of public officials.

            In giving its opinion required by this subsection (e) of this
      Section 7, such counsel shall additionally state that such counsel has
      participated in conferences with officers and other representatives of the
      Issuers, representatives of the independent accountants for the Issuers,
      United States and Brazilian counsel to the Issuers, representatives of the
      Initial Purchasers and United States counsel to the Initial Purchasers at

      Offering Memorandum (except and only to the extent set forth in clause
      (7), (19), and (26) of subsection (b) of this Section 7), on the basis of
      the foregoing (relying as to materiality to a large extent upon the
      representations and opinions of officers and other representatives of the
      Issuers), no facts have come to the attention of such counsel which lead
      such counsel to believe that the Offering Memorandum, at the date thereof,
      contained an untrue statement of a material fact or omitted to state a
      material fact necessary to make the statements therein, in the light of
      the circumstances under which they were made, not misleading (it being

      thereto and related schedules, (ii) other financial or statistical data
      found in or derivable from the financial, accounting or internal records

      financial or statistical data relating to the Issuers, in each case,
      included in the Offering Memorandum).

            (f) The following conditions contained in clauses (i) and (ii) of
      this subsection (f) shall have been satisfied at and as of the Closing
      Time and (x) the Company shall have furnished to the Initial Purchasers a
      certificate, signed by the President and the principal financial or

      the Initial Purchasers a certificate, signed by two Members of the
      Management Committee (at least one of whom shall also be a Manager of the
      LLC); each such certificate shall be dated as of the Closing Time and
      shall be to the effect that the signers of such certificate have examined
      the Offering Memorandum, any amendment or supplement to the Offering
      Memorandum, and this Agreement and that:

                  (i) the representations and warranties of the Issuers in this
            Agreement are true and correct in all material respects on and as of
            the Closing Time with the same effect as if made at the Closing Time
            and the Issuers have complied with all the agreements and satisfied
            all the conditions under this Agreement on their part to be
            performed or satisfied at or prior to the Closing Time; and

                 (ii) since the date of the most recent financial statements
            included in the Offering Memorandum (exclusive of any amendment or
            supplement thereto), there has been no Material Adverse Change,
            whether or not arising in the ordinary course of business. As used
            in this subparagraph, the term "Offering Memorandum" means the
            Offering Memorandum in the form first used to confirm sales of the
            Securities.

            (g) At the time that this Agreement is signed and at the Closing
      Time, Ernst & Young Auditores Independentes S.C. shall have furnished to
      the Initial Purchasers a letter or letters, dated respectively as of the
      date of this Agreement and as of the Closing Time, in form and sub-

      stance satisfactory to the Initial Purchasers, confirming that they are
      independent certified public accountants within the meaning of the Act and
      the applicable published rules and regulations thereunder and containing
      statements and information of the type ordinarily included in accountants'
      "comfort letters" to initial purchasers and underwriters with respect to
      financial statements and certain financial information contained in the
      Offering Memorandum.

            (h) Subsequent to the date hereof or, if earlier, the dates as of
      which information is given in the Offering Memorandum (exclusive of any
      amendment or supplement thereto), there shall not have been any change, or
      any development involving a prospective change, in or affecting the
      business or properties of the Issuers the effect of which is, in the
      reasonable judgment of Merrill Lynch, so material and adverse as to make
      it impractical or inadvisable to proceed with the purchase and the
      delivery of the Securities as contemplated by the Offering Memorandum
      (exclusive of any amendment or supplement thereto).

            (i) All government authorizations required in connection with the
      issue and sale of the Securities as contemplated under this Agreement and
      the performance of the Issuers' respective obligations hereunder and under
      Indenture, the Agency Agreement, the Company-LLC Subscription Agreement,
      the Units, the Notes, the Exchange Notes, the Private Exchange Notes, the
      Holding Shares and the Common Stock delivered to the LLC pursuant to the
      Subscription Agreement shall be in full force and effect and the Issuers

      the Prior Authorization of the Brazilian Central Bank) to the Initial
      Purchasers and there shall have been no indication from the Brazilian
      Central Bank that the Registration Certificate will not be forthcoming.

      reasonably require for the purpose of enabling them to pass upon the
      issuance and sale of the Securities as contemplated herein and related
      proceedings, or in order to evidence the accuracy of any of the
      representations or warranties, or the fulfillment of any of the
      conditions, herein contained; and all opinions and certificates mentioned

      required to establish the Escrow Account with the Escrow Agent and to
      prepare to file appropriate financing statements in each of the offices
      where such filing is necessary or, in the opinion of the Initial
      Purchasers, desirable to perfect the lien in favor of the Trustee created
      by the Escrow Agreement.

            (m) The Issuers and the Initial Purchasers shall have entered into
      the Notes Registration Rights Agreement.

                                      -67-


            (q) The Issuers shall have executed the Agency Agreement and CT
      Corporation System shall have accepted its appointment thereunder.

            (r) The Shareholder Commitments shall have been executed and

            If any condition specified in this Section 7 shall not have been
fulfilled in all material respects when and as required to be fulfilled, this
Agreement may be terminated by the Initial Purchasers by notice to the Issuers,
and such termination shall be without liability of any party to any other party
except as provided in Section 6. Notwithstanding any such termination, the
provisions of Sections 1, 8, 18 and 19 shall remain in effect. Notice of such
cancellation shall be given to the Issuers in writing or by telephone, facsimile
transmission or telegraph confirmed in writing. The Issuers shall furnish to the
Initial Purchasers such conformed copies of such opinions, certificates, letters
and documents in such quantities as the Initial Purchasers and counsel for the
Initial Purchasers shall reasonably request.

            SECTION 8. Indemnification.

            (a) Indemnification of Initial Purchasers. Each of the Issuers
agrees, jointly and severally, to indemnify and hold harmless each Initial
Purchaser and each person, if any, who controls any Initial Purchaser within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act as follows:

            (i) against any and all loss, liability, claim, damage and expense
      whatsoever, as incurred, arising out of any untrue statement or alleged
      untrue statement of a material fact contained in the Preliminary Offering
      Memorandum or the Final Offering Memorandum (or any amendment or
      supplement thereto), or the omission or alleged omission therefrom of a
      material fact necessary in order to make the statements therein, in the
      light of the circumstances under which they were made, not misleading;
<PAGE>
                                      -68-


            (ii) against any and all loss, liability, claim, damage and expense
      whatsoever, as incurred, to the extent of the aggregate amount paid in
      settlement of any litigation, or any investigation or proceeding by any
      governmental agency or body, commenced or threatened, or of any claim
      whatsoever based upon any such untrue statement or omission, or any such
      alleged untrue statement or omission; provided that (subject to Section
      8(d) below) any such settlement is effected with the written consent of
      the Company; and

            (iii) against any and all expense whatsoever, as incurred (including
      the reasonable fees and disbursements of counsel chosen by Merrill Lynch),
      reasonably incurred in investigating, preparing or defending against any
      litigation, or any investigation or proceeding by any governmental agency
      or body, commenced or threatened, or any claim whatsoever based upon any
      such untrue statement or omission, or any such alleged untrue statement or
      omission, to the extent that any such expense is not paid under (i) or
      (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
Initial Purchaser through Merrill Lynch expressly for use in the Offering
Memorandum (or any amendment thereto).

            (b) Indemnification of Issuers, Directors and Officers. Each Initial
Purchaser severally agrees to indemnify and hold harmless the Issuers, its
directors and each person, if
<PAGE>
                                      -69-


any, who controls any of the Issuers within the meaning of Section 15 of the Act
or Section 20 of the Exchange Act against any and all loss, liability, claim,
damage and expense described in the indemnity contained in subsection (a) of
this Section 8, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions made in the Offering
Memorandum in reliance upon and in conformity with written information furnished
to the Issuers by such Initial Purchaser through Merrill Lynch expressly for use
in the Offering Memorandum.

            (c) Actions against Parties; Notification. Each indemnified party
shall give notice as promptly as reasonably practicable to each indemnifying
party of any action commenced against it in respect of which indemnity may be
sought hereunder, but failure to so notify an indemnifying party shall not
relieve such indemnifying party from any liability hereunder to the extent it is
not materially prejudiced as a result thereof and in any event shall not relieve
it from any liability which it may have otherwise than on account of this
indemnity agreement. In the case of parties indemnified pursuant to Section 8(a)
above, counsel to the indemnified parties shall be selected by Merrill Lynch,
and, in the case of parties indemnified pursuant to Section 8(b) above, counsel
to the indemnified parties shall be selected by the Issuers. Notwithstanding the
foregoing sentence, in case any such action is brought against any indemnified
party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein and, to the extent it
may wish, jointly with any other indemnifying party similarly notified, unless
such indemnified party shall have one or more legal defenses available to it
which are not available to the indemnifying party, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party. After
notice from the indemnifying party to such indemnified party of its election as
aforesaid to assume the defense thereof and approval by such indemnified party
of counsel appointed to defend such action, the indemnifying party will not be
liable to such indemnified party under this Section 8 for any legal or other
expenses other than reasonable costs of investigation, subsequently incurred by
such indemnified party in connection with the defense thereof. An indemnifying
party may participate at its own expense in the 
<PAGE>
                                      -70-


defense of any such action; provided, however, that counsel to the indemnifying
party shall not (except with the consent of the indemnified party) also be
counsel to the indemnified party. In no event shall the indemnifying parties be
liable for fees and expenses of more than one counsel (in addition to any local
counsel) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising
<PAGE>
                                      -71-


out of the same general allegations or circumstances. No indemnifying party
shall, without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 8 or Section
9 hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to or an admission of fault, culpability or a failure to act by
or on behalf of any indemnified party.

            (d) Settlement Without Consent if Failure To Reimburse. If at any
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel, such
indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by Section 8(a)(ii) effected without its written consent if
(i) such settlement is entered into more than 45 days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
have received notice of the terms of such settlement at least 30 days prior to
such settlement being entered into and (iii) such indemnifying party shall not
have reimbursed such indemnified party in accordance with such request prior to
the date of such settlement.

            SECTION 9. Contribution. If the indemnification provided for in
Section 8 hereof is for any reason unavailable to or insufficient to hold
harmless an indemnified party in respect of any losses, liabilities, claims,
damages or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount of such losses, liabilities, claims, damages
and expenses incurred by such indemnified party, as incurred, (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Issuers on the 
<PAGE>
                                      -72-


one hand and the Initial Purchasers on the other hand from the offering of the
Securities pursuant to this Agreement or (ii) if the allocation provided by
clause (i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Issuers on the one hand and of the
Initial Purchasers on the other hand in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

            The relative benefits received by the Issuers on the one hand and
the Initial Purchasers on the other hand in connection with the offering of the
Securities pursuant to this Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of the
Securities pursuant to this Agreement (before deducting expenses) received by
the Company and the total underwriting discount received by the Initial
Purchasers, bear to the aggregate initial offering price of the Securities.

            The relative fault of the Issuers on the one hand and the Initial
Purchasers on the other hand shall be determined by reference to, among other
things, whether any such untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by the Issuers or by the Initial Purchasers and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

            The Issuers and the Initial Purchasers agree that it would not be
just and equitable if contribution pursuant to this Section 9 were determined by
pro rata allocation (even if the Initial Purchasers were treated as one entity
for such purpose) or by any other method of allocation which does not take
account of the equitable considerations referred to above in this Section 9. The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 9 shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending 
<PAGE>
                                      -73-


against any litigation, or any investigation or proceeding by any governmental
agency or body, commenced or threatened, or any claim whatsoever based upon any
such untrue or alleged untrue statement or omission or alleged omission.

            Notwithstanding the provisions of this Section 9, no Initial
Purchaser shall be required to contribute any amount in excess of the amount by
which the total price at which the Securities underwritten by it and distributed
to the public were offered to the public exceeds the amount of any damages which
such Initial Purchaser has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission.

            No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

            For purposes of this Section 9, each person, if any, who controls an
Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of
the Exchange Act shall have the same rights to contribution as such Initial
Purchaser, and each director of any of the Issuers, each officer, director or
member of any of the Issuers and each person, if any, who controls any of the
Issuers within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act shall have the same rights to contribution as the Company. The
Initial Purchasers' respective obligations to contribute pursuant to this
Section 9 are several in proportion to the number of Securities set forth
opposite their respective names in Schedule A hereto and not joint.

            SECTION 10. Representations, Warranties and Agreements To Survive
Delivery. All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Issuers submitted pursuant
hereto, shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of any Initial Purchaser or controlling
person, or by or on behalf of the Issuers, and 
<PAGE>
                                      -74-


shall survive delivery of the Securities to the Initial Purchasers.

            SECTION 11. Termination of Agreement.

            (a) Termination: General. The Initial Purchasers may terminate this
Agreement, by notice to any of the Issuers, at any time at or prior to the
Closing Time (i) if there has been, since the time of execution of this
Agreement or since the respective dates as of which information is given in the
Offering Memorandum, any material adverse change in the condition, financial or
otherwise, or in the earnings, business affairs or business prospects of the
Issuers considered as one enterprise, whether or not arising in the ordinary
course of business, or (ii) if there has occurred any material adverse change in
the financial markets in the United States, Brazil, Latin America generally or
in the international financial markets, any outbreak of hostilities or
escalation thereof or other calamity or crisis or any change or development
involving a prospective change in national or international political, financial
or economic conditions, in each case the effect of which is such as to make it,
in the reasonable judgment of the Initial Purchasers, impracticable to market
the Securities or to enforce contracts for the sale of the Securities, or (iii)
if trading generally on the American Stock Exchange, the New York Stock
Exchange, the Sao Paulo Stock Exchange or the Rio de Janeiro Stock Exchange, in
the NASDAQ National Market System or in the PORTAL market has been suspended or
limited, or minimum or maximum prices for trading have been fixed, or maximum
ranges for prices have been required, by any of said exchanges or by such system
or by order of the Comissao de Valores Mobiliarios, the Commission, the National
Association of Securities Dealers, Inc. or any governmental authority, or (iv)
if a banking moratorium has been declared by either United States Federal or New
York authorities or by the Brazilian Central Bank or any other competent
governmental authority in the Federative Republic of Brazil or any political
subdivision thereof.

            (b) Liabilities. If this Agreement is terminated pursuant to this
Section, such termination shall be without li-
<PAGE>
                                      -75-


ability of any party to any other party except as provided in Section 6 hereof,
and provided further that Sections 1, 8, 9, 18 and 19 shall survive such
termination and remain in full force and effect.

            SECTION 12. Default By One of the Initial Purchasers. If one or more
of the Initial Purchasers shall fail at the Closing Time to purchase the
Securities which it or they are obligated to purchase under this Agreement (the
"Defaulted Securities"), Merrill Lynch shall have the right, but not the
obligation, within 24 hours thereafter, to make arrangements for one or more of
the nondefaulting Initial Purchasers, or any other Initial Purchasers, to
purchase all, but not less than all, of the Defaulted Securities in such amounts
as may be agreed upon and upon the terms herein set forth; if, however, Merrill
Lynch shall not have completed such arrangements within such 24-hour period,
then this Agreement shall terminate without liability on the part of any
nondefaulting Initial Purchaser.

            No action pursuant to this Section shall relieve any defaulting
Initial Purchaser from liability in respect of its default.

            In the event of any such default which does not result in a
termination of this Agreement, either the non-defaulting Initial Purchaser or
the Issuers shall have the right to postpone the Closing Time for a period not
exceeding seven days in order to effect any required changes in the Offering
Memorandum or in any other documents or arrangement.

            SECTION 13. Notices. All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given if mailed (and
in the case of Section 18, certified, return receipt requested) or (other than
in the case of Section 18) transmitted by any standard form of
telecommunication. Notices to the Initial Purchasers shall be directed to the
Initial Purchasers c/o Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner &
Smith Incorporated, Merrill Lynch World Headquarters, North Tower, World
Financial Center, New York, New York 10281-1305, attention of Christopher A.

at Rua Alexandre Dumas, 1.711-1 andar, 04717-910-Birmann 12-Chacara Santo
Antonio, Sao Paolo, Attention: Thomas C. Trynin, President; and notices to the
LLC shall be directed to the LLC's offices c/o Warburg, Pincus Ventures L.P.,
466 Lexington Avenue, New York, New York 10017, Attention: Douglas M. Karp.

            SECTION 14. Information Supplied by the Initial Purchasers. The
statement set forth in the last paragraph on the inside front cover page in the
Offering Memorandum (to the extent such statement relates to the Initial
Purchasers) and the information specifically relating to the Initial Purchasers
under the caption "Plan of Distribution" in the Offering Memorandum constitute
the only information furnished by the Initial Purchasers to the Company for the
purposes of Sections 1, 8 and 9 hereof.

            SECTION 15. Parties. This Agreement shall inure to the benefit of
and be binding upon the Initial Purchasers and the Issuers and their respective
successors and legal representatives. Nothing expressed or mentioned in this
Agreement is intended or shall be construed to give any person, firm or
corporation, other than the Initial Purchasers and the Issuers and their
respective successors and legal representatives and the controlling persons and
officers, directors, employees and agents referred to in Sections 8, 9 and 19
and their heirs and legal representatives, any legal or equitable right, remedy
or claim under, by virtue of or in respect of this Agreement or any provision
herein contained. This Agreement and all conditions and provisions hereof are
intended to be for the sole and exclusive benefit of the Initial Purchasers and
the Issuers and their respective successors and legal representatives, and said
controlling persons and officers, directors, employees and agents and their
heirs and legal representatives, and for the benefit of no other person, firm or
corporation. No purchaser of Securities from any Initial Purchaser shall be
deemed to be a successor by reason merely of such purchase.

            SECTION 16. Governing Law and Time. THIS AGREEMENT SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS 
<PAGE>
                                      -77-


OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY PROVISIONS RELATING TO
CONFLICTS OF LAWS. Specified times of day refer to New York City time.

            SECTION 17. Counterparts. This Agreement may be executed by manual
or facsimile signature in one or more counterparts and, when each party has
executed a counterpart, all such counterparts taken together shall constitute
one and the same agreement.

            SECTION 18. Agent for Service; Submission to Jurisdiction; Waiver of
Immunities. By the execution and delivery of this Agreement, the Company (i)
acknowledges that it has, by separate written instrument, designated and
appointed CT Corporation System, 1633 Broadway, New York, NY 10019 ("CT
Corporation System") (and any successor entity), as its authorized agent upon
which process may be served in any suit or proceeding arising out of or relating
to this Agreement that may be instituted in any federal or state court in The
City of New York, Borough of Manhattan, State of New York or brought under
federal or state securities laws, and acknowledge that CT Corporation System has
accepted such designation, (ii) submits to the jurisdiction of any such court in
any such suit or proceeding and (iii) agrees that service of process upon CT
Corporation System and written notice of said service to the Company in
accordance with Section 13 shall be deemed in every respect effective service of
process upon the Company, in any such suit or proceeding. The Company further
agrees to take any and all action, including the execution and filing of any and
all such documents and instruments, as may be necessary to continue such
designation and appointment of CT Corporation System in full force and effect so
long as any of the Units, the Notes, the Exchange Notes or the Private Exchange
Notes shall be outstanding; provided that the Company may and to the extent CT
Corporation System ceases to be able to be served on the basis contemplated
herein shall, by written notice to the Initial Purchasers, designate such
additional or alternative agent for service of process under this Section 18
that (i) maintains an office located in the Borough of Manhattan, City of New
York, State of New York and (ii) is either (x) counsel for the Com-
<PAGE>
                                      -78-


pany or (y) a corporate service company which acts as agent for service of
process for other persons in the ordinary course of its business. Such written
notice shall identify the name of such agent for service of process and the
address of the office of such agent for service of process in the Borough of
Manhattan, City of New York, State of New York.

            To the extent that the Company has or hereafter may acquire any
immunity from jurisdiction of any court of (i) any jurisdiction in which the
Company owns or leases property or assets, (ii) the United States or the State
of New York or (iii) the Federative Republic of Brazil or any political
subdivision thereof or from any legal process (whether through service of
notice, attachment prior to judgment, attachment in aid of execution, execution
or otherwise) with respect to itself or its property and assets or this
Agreement or any of the Units, the Notes, Exchange Notes or Private Exchange
Notes or actions to enforce judgments in respect of any thereof, the Company
hereby irrevocably waives such immunity in respect of its obligations under the
above-referenced documents, to the extent permitted by law.

            SECTION 19. Judgment Currency. Each of the Issuers hereby jointly
and severally agrees to indemnify each Purchaser and each Person, if any, who
controls any Initial Purchaser within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act and each of their respective officers, directors,
employees and agents against any loss incurred by such party as a result of any
judgment or order being given or made for any U.S. dollar amount due under this
Agreement and such judgment or order being expressed and paid in a currency (the
"Judgment Currency") other than United States dollars and as a result of any
variation as between (i) the rate of exchange at which the United States dollar
amount is converted into the Judgment Currency for the purpose of such judgment
or order and (ii) the spot rate of exchange in The City of New York at which
such party on the date of payment of such judgment or order is able to purchase
United States dollars with the amount of the Judgment Currency actually received
by such party. The foregoing indemnity shall continue in full force and effect
notwith-
<PAGE>
                                      -79-


standing any such judgment or order as aforesaid. The term "spot rate of
exchange" shall include any premiums and costs of exchange payable in connection
with the purchase of, or conversion into, United States dollars.

            SECTION 20. Prior Agreements Superseded. This Agreement supersedes
all prior agreements, undertakings and arrangements, oral or written, among the
parties hereto with respect to the subject matter hereof.
<PAGE>
                                      -80-


            If the foregoing is in accordance with your understanding of our
agreement, please sign and return to each of the Issuers a counterpart hereof,
whereupon this instrument, along with all counterparts, will become a binding
agreement between the Initial Purchasers and the Issuers in accordance with its
terms.

                                       Very truly yours,

the benefit of the Holders, at the Issuers' cost, use their reasonable best

the Exchange Offer to be consummated not later than 150 days after the Closing
Time. The Exchange Notes will be issued under the Indenture. Upon the
effectiveness of the Exchange Offer Registration Statement, the Issuers shall
promptly commence the Exchange Offer, it being the objective of such Exchange
Offer to enable each Holder eligible and electing to exchange Registrable Notes
for Exchange Notes (assuming that such Holder is not an affiliate of any of the
Issuers within the meaning of Rule 405 under the 1933 Act and is not a

terial restrictions under the securities laws of a substantial proportion of the

            (i) mail to each Holder a copy of the Prospectus forming part of the
      Exchange Offer Registration Statement, together with an appropriate letter
      of transmittal and related documents;

            (ii) keep the Exchange Offer open for acceptance for a period of not
      less than 30 days after the date notice thereof is mailed to the Holders
      (or longer if required by applicable law) (such period referred to herein
      as the "Exchange Period");

            (iii) utilize the services of the Depositary for the Exchange Offer;

            (iv) permit Holders to withdraw tendered Notes at any time prior to
      the close of business, New York time, on the last business day of the
      Exchange Period, by sending to the institution specified in the notice, a
      telegram, telex, facsimile transmission or letter setting forth the name
      of such Holder, the principal amount of Notes delivered for exchange, and
      a statement that such Holder is withdrawing his election to have such
      Notes exchanged;

            (v) notify each Holder, by notice which may be included in any of
      the documents listed in paragraph 2(a)(i) of this Section 2, that any Note
      not tendered will remain outstanding and continue to accrue interest, but
      will not retain any rights under this Agreement (except in the case of the
      Purchasers and Participating Broker-Dealers and in connection with any
      Special Private Exchange as provided herein); and

            (vi) otherwise comply in all respects with all applicable laws
      relating to the Exchange Offer.
<PAGE>
                                      -9-


            If, prior to consummation of the Exchange Offer, the Purchasers hold
any Notes acquired by them and having the status of an unsold allotment in the
initial distribution, the Issuers upon the request of the Purchasers shall,
simultaneously with the delivery of the Exchange Notes in the Exchange Offer,
issue and deliver to the Purchasers, in exchange (the "Private Exchange" (which
term shall also be deemed to refer to any Special Private Exchange (as defined
below) unless the context otherwise requires)) for the Notes held by the
Purchasers, a like principal amount of debt securities (the "Private Exchange
Notes" (which term shall also be deemed to refer to the Special Private Exchange
Notes (as defined below) unless the context otherwise requires)) of the Company,
guaranteed by each of the Guarantors on a senior unsecured basis, that are
identical (except that all of the Private Exchange Notes other than the Special
Private Exchange Notes shall bear appropriate transfer restrictions) to the
Exchange Notes and which are issued pursuant to the Indenture (which will
provide that the Exchange Notes will not be subject to the transfer restrictions
set forth in the Indenture and that the Exchange Notes, the Private Exchange
Notes (including the Special Private Exchange Notes) and the Notes will vote and
consent together on all matters as one class and that neither the Exchange
Notes, the Private Exchange Notes, the Special Private Exchange Notes nor the
Notes will have the right to vote or consent as a separate class on any matter).
The Private Exchange Notes (including the Special Private Exchange Notes) shall
be of the same series as and shall bear the same CUSIP number as the Exchange
Notes.

            Following the Exchange Offer, any Holder of Registrable Notes who
holds such Registrable Notes in the form of Offshore Physical Securities or
Offshore Global Securities (each as defined in the Indenture) and who did not
participate in the Exchange Offer may present such Registrable Notes to the
Company for exchange (a "Special Private Exchange") and the Company shall issue
in exchange for such Registrable Notes a like principal amount of debt
securities ("Special Private Exchange Notes") of the Company issued pursuant to
the Indenture and guaranteed by each of the Guarantors on a senior unsecured
basis which are identical to the Exchange Notes and which are of 
<PAGE>
                                      -10-


the same series and bear the same CUSIP number as the Exchange Notes.

            As soon as practicable after the close of the Exchange Offer, the
Private Exchange or the Special Private Exchange, as the case may be, the
Issuers shall:

            (i) accept for exchange all Notes or portions thereof tendered and
      not validly withdrawn pursuant to the Exchange Offer, Private Exchange or
      Special Private Exchange, as the case may be;

            (ii) accept for exchange all Notes duly tendered pursuant to the
      Exchange Offer, the Private Exchange or the Special Private Exchange; and

            (iii) deliver, or cause to be delivered, to the Trustee for
      cancellation all Notes or portions thereof so accepted for exchange by the
      Issuers, and issue, and cause the Trustee under the Indenture to promptly
      authenticate and deliver to each Holder, a new Exchange Note, Private
      Exchange Note or Special Private Exchange Note, as the case may be, equal
      in principal amount to the principal amount of the Notes surrendered by
      such Holder.

To the extent not prohibited by any law or applicable interpretation of the
staff of the SEC, the Issuers shall use their reasonable best efforts to
complete the Exchange Offer as provided above, and shall comply with the
applicable requirements of the 1933 Act, the 1934 Act and other applicable laws
in connection with the Exchange Offer. The Exchange Offer shall not be subject
to any conditions, other than that the Exchange Offer does not violate
applicable law or any applicable interpretation of the staff of the SEC. Each
Holder of Registrable Notes who wishes to exchange such Registrable Notes for
Exchange Notes in the Exchange Offer will be required to make certain customary
representations in connection therewith, including representations that such
Holder is not an affiliate of any of the Issuers within the meaning of Rule 405
under the 1933 Act, that any Exchange Notes to be received by it will be
acquired in the ordinary course of business and that at the 
<PAGE>
                                      -11-


time of the commencement of the Exchange Offer it has no arrangement with any
Person to participate in the distribution (within the meaning of the 1933 Act)
of the Exchange Notes. The Issuers shall inform the Purchasers, after
consultation with the Trustee and the Purchasers, of the names and addresses of
the Holders to whom the Exchange Offer is made, and the Purchasers shall have
the right to contact such Holders and otherwise facilitate the tender of
Registrable Notes in the Exchange Offer.

            In connection with any Special Private Exchange, the Company may
require the Holder of Registrable Notes to provide appropriate representations
or undertakings to the extent required to comply with the 1933 Act.

            Upon consummation of the Exchange Offer in accordance with this
Section 2(a), the provisions of this Agreement shall continue to apply, mutatis
mutandis, solely with respect to Registrable Notes that are Private Exchange
Notes and Exchange Notes held by Participating Broker-Dealers, and the Issuers
shall have no further obligation to register Registrable Notes (other than
Private Exchange Notes) pursuant to Section 2(b) of this Agreement.

            (b) Notes Shelf Registration. In the event that (i) the Issuers or
the the Holders of a majority of the Notes reasonably determine, after
conferring with counsel, that the Exchange Offer Registration provided in
Section 2(a) above is not available or may not be consummated as soon as
practicable after the last day of the Exchange Period because it would violate
applicable securities laws or because the applicable interpretations of the
staff of the SEC would not permit the Issuers to effect the Exchange Offer, or
(ii) the Exchange Offer is not for any other reason consummated within 150 days
of the Closing Time, or (iii) any Holder notifies the Company prior to
commencement of the Exchange Offer that (a) due to a change in law or policy it
is not entitled to participate in the Exchange Offer, (b) due to a change in law
or policy it may not resell the Exchange Notes acquired by it in the Exchange
Offer to the public without delivering a prospectus and the prospectus contained
in the Exchange Offer Registration Statement is not ap-
<PAGE>
                                      -12-


propriate or available for such resales by such Holder or (c) it is a
broker-dealer and owns Notes acquired directly from the Company or an affiliate
of the Company or any Guarantor, or (iv) the Holders of a majority of the Notes
may not resell the Exchange Notes acquired by them in the Exchange Offer to the
public without restriction under the 1933 Act and without restriction under
applicable blue sky or state securities laws, the Issuers shall, at their cost,
use their best efforts to cause to be filed prior to the later of (a) 90 days
after the Closing Time or (b) 30 days after such filing obligation arises, a
Notes Shelf Registration Statement providing for the sale by the Holders of all
of the Registrable Notes, and shall use their best efforts to have such Notes
Shelf Registration Statement declared effective by the SEC on or prior to 60
days after such Notes Shelf Registration Statement is required to be filed;
provided that if the Company has not consummated the Exchange Offer within 150
days of the Closing Time, then the Issuers will file the Notes Shelf
Registration Statement with the SEC on or prior to the 151st day after the
Closing Time. No Holder of Registrable Notes may include any of its Registrable
Notes in any Notes Shelf Registration pursuant to this Agreement unless and
until such Holder furnishes to the Issuers in writing, within 15 days after
receipt of a request therefor, such information as the Issuers may, after
conferring with counsel with regard to information relating to Holders that
would be required by the SEC to be included in such Notes Shelf Registration
Statement or Prospectus included therein, reasonably request for inclusion in
any Notes Shelf Registration Statement or Prospectus included therein. Each
Holder as to which any Notes Shelf Registration is being effected agrees to
furnish promptly to the Issuers all information to be disclosed in the
applicable Notes Shelf Registration Statement or Prospectus included therein in
order to make the information previously furnished to the Issuers by such Holder
not materially misleading.

            The Issuers agree to use their reasonable best efforts to keep the
Notes Shelf Registration Statement continuously effective, supplemented and
amended for a period of two years (or such shorter period as required by Rule
144(k) under 
<PAGE>
                                      -13-


the 1933 Act) from the effective date of the Notes Shelf Registration Statement
(subject to extension pursuant to the last paragraph of Section 3) (the
"Effectiveness Period"); provided that if such Notes Shelf Registration
Statement has been filed solely at the request of a Holder pursuant to clause
(iv) above, the Issuers shall only be required to use their reasonable best
efforts to keep such Notes Shelf Registration Statement continuously effective
for a period of one year from the date of issuance of the Notes (subject to
extension pursuant to the last paragraph of Section 3 hereof) or for such
shorter period which will terminate when all of the Registrable Notes covered by
the Notes Shelf Registration Statement have been sold pursuant to the Notes
Shelf Registration Statement or cease to be outstanding and provided further
that the Company may suspend the effectiveness of the Shelf Registration
Statement for a period (a "Black Out Period") not to exceed an aggregate of 90
days if (i) an event occurs and is continuing as a result of which the Shelf
Registration Statement would, in the Company's good faith judgment, contain an
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements therein, in the light of the circumstances under
which they were made, not misleading and (ii) (a) the Company determines in its
good faith judgment that the disclosure of such event at such time would have a
material adverse effect on the business, operations or prospects of the Company
or (b) the disclosure otherwise relates to a pending material business
transaction which has not been publicly disclosed. The Issuers shall not permit
any notes other than Registrable Notes to be included in the Notes Shelf
Registration. The Issuers further agree, if necessary, to supplement or amend
the Notes Shelf Registration Statement, if required by the rules, regulations or
instructions applicable to the registration form used by the Issuers for such
Notes Shelf Registration Statement or by the 1933 Act or by any other rules and
regulations thereunder for shelf registrations, and the Issuers agree to furnish
to the Holders of Registrable Notes copies of any such supplement or amendment
promptly after its being used or filed with the SEC.
<PAGE>
                                      -14-


            (c) Expenses. The Issuers shall pay all Registration Expenses in
connection with the registration pursuant to Section 2(a) or 2(b) and will
reimburse the Purchasers for the reasonable fees and disbursements of Cahill
Gordon & Reindel incurred in connection with the Registered Exchange Offer and
any one counsel designated in writing by the the Holders of a majority of the
Notes to act as counsel for the Holders of the Registrable Notes in connection
with a Notes Shelf Registration Statement. Each Holder shall pay all expenses of
its counsel other than as set forth in the preceding sentence, underwriting
discounts and commissions and transfer taxes, if any, relating to the sale or
disposition of such Holder's Registrable Notes pursuant to the Notes Shelf
Registration Statement.

            (d) Effective Registration Statement. An Exchange Offer Registration
Statement pursuant to Section 2(a) hereof or a Notes Shelf Registration
Statement pursuant to Section 2(b) hereof will not be deemed to have become
effective unless it has been declared effective by the SEC; provided that if,
after it has been declared effective, the offering of Registrable Notes pursuant
to a Notes Shelf Registration Statement is interfered with by any stop order,
injunction or other order or requirement of the SEC or any other governmental
agency or court, such Notes Registration Statement will be deemed not to have
been effective during the period of such interference, until the offering of
Registrable Notes pursuant to such Notes Registration Statement may legally
resume. The Issuers will be deemed not to have used their reasonable efforts to
cause the Exchange Offer Registration Statement or the Notes Shelf Registration
Statement, as the case may be, to become, or to remain, effective during the
requisite period if they voluntarily take any action that would result in any
such Notes Registration Statement not being declared effective or in the Holders
of Registrable Notes covered thereby not being able to exchange or offer and
sell such Registrable Notes during that period unless such action is required by
applicable law.

            (e) Additional Interest. In the event that either (i) the Issuers
fail to file the Exchange Offer Registration Statement or the Notes Shelf
Registration Statement, as the 
<PAGE>
                                      -15-


case may be, on or before the date specified for any such filing hereunder, (ii)
the Issuers fail to consummate the Exchange Offer pursuant to an effective
Exchange Offer Registration Statement on or prior to the 150th day following the
Closing Time or (iii) if the law or applicable interpretations of the SEC
thereof prohibit a Holder from participating in the Exchange Offer or if such
Holder does not receive freely tradeable Exchange Notes pursuant to the Exchange
Offer or if for any reason the Exchange Offer is not consummated within 150 days
of the Closing Time, and if by 150 days after the Closing Time a Notes Shelf
Registration Statement is not declared effective (each such event referred to in
clauses (i) through (iii) above, a "Registration Default"), the interest rate
borne by all Registrable Notes shall be increased ("Additional Interest") by
one-half of one percent per annum during the first 90-day period immediately
following the occurrence of such Registration Default. In addition, such rate of
Additional Interest shall be increased by an additional one-half of one percent
per annum for each 90-day period that any Additional Interest continues to
accrue pursuant to this Section 2(e); provided that the aggregate increase in
such interest rate pursuant to this Section 2(e) will in no event exceed two
percent per annum. Following the cure of all Registration Defaults, the accrual
of Additional Interest shall cease and the interest rate borne by all
Registrable Notes shall revert to the original rate.

            In the event that the Notes Shelf Registration Statement has been
declared effective and subsequently ceases to be effective prior to the end of
the Effectiveness Period, or if such Notes Shelf Registration Statement was
filed solely at the request of the Purchasers pursuant to Section 2(b)(iv)
hereof, one year after the date of issuance of the Notes (in each instance,
subject to extension pursuant to the last paragraph of Section 3 hereof), for a
period in excess of 90 days, whether or not consecutive, during the term hereof,
then the interest rate borne by the Notes or the Private Exchange Notes, as the
case may be, shall be increased by an additional one-half of one percent per
annum on the 91st day such Notes Shelf Registration Statement ceases to be
effective. Such interest rate shall be increased by an additional one-half of
one percent per 
<PAGE>
                                      -16-


annum for each additional 90 days that such Notes Shelf Registration Statement
is not effective, subject to an aggregate maximum increase in the interest rate
per annum of two percent. Upon the effectiveness of a Notes Shelf Registration
Statement, the interest rate borne by the Notes or the Private Exchange Notes,
as the case may be, shall be reduced to the original interest rate unless and
until increased as described in this paragraph.

            The Issuers shall notify the Trustee within three business days
after each and every date on which an event occurs in respect of which
Additional Interest is required to be paid (an "Event Date"). Additional
Interest shall be paid by depositing with the Trustee, in trust, for the benefit
of the Holders of Notes or of Private Exchange Notes, as the case may be, on or
before the applicable semiannual interest payment date, immediately available
funds in sums sufficient to pay the Additional Interest then due. The Additional
Interest due shall be payable on each interest payment date to the record Holder
of Notes entitled to receive the interest payment to be paid on such date as set
forth in the Indenture. Each obligation to pay Additional Interest shall be
deemed to accrue from and including the day following the applicable Event Date.

            The Issuers agree to use their best efforts to seek and obtain all
registrations, approvals and consents of any governmental agency or body,
including but not limited to the Central Bank of Brazil, to permit the lawful
payment by the Issuers of the Additional Interest provided for herein.

            (f) Specific Enforcement. Without limiting the remedies available to
the Purchasers and the Holders, the Issuers acknowledge that any failure by the
Issuers to comply with their obligations under Section 2(a) and Section 2(b)
hereof may result in material irreparable injury to the Purchasers or the
Holders for which there is no adequate remedy at law, that it would not be
possible to measure damages for such injuries precisely and that, in the event
of any such failure, the Purchasers or any Holder may obtain such relief as may
be required to specifically enforce the Issuers' obligations under Section 2(a)
and Section 2(b) hereof.

            3. Registration Procedures. In connection with the obligations of
the Issuers with respect to the Registration Statements pursuant to Sections
2(a) and 2(b) hereof, the Issuers shall:

            (a) prepare and file with the SEC a Registration Statement or
      Registration Statements as prescribed by Sections 2(a) and 2(b) hereof

      appropriate form under the 1933 Act, which form (i) shall be selected by
      the Issuers, (ii) shall, in the case of a Notes Shelf Registration, be
      available for the sale of the Registrable Notes by the selling Holders

      reasonable best efforts to cause such Notes Registration Statement to
      become effective and remain effective in accordance with Section 2 hereof;
      provided that if (1) such filing is -------- pursuant to Section 2(b), or
      (2) a Prospectus contained in a Notes Exchange Offer Registration
      Statement filed pursuant to Section 2(a) is required to be delivered under
      the 1933 Act by any Participating Broker-Dealer who seeks to sell Exchange
      Notes, before filing any Notes Registration Statement or Prospectus or any
      amendments or supplements thereto, the Issuers shall furnish to and afford
      the Holders of the Registrable Notes and each such Participating
      Broker-Dealer, as the case may be, covered by such Notes Registration
      Statement, their counsel and the managing underwriters, if any, a
      reasonable opportunity to review copies of all such documents (including
      copies of any documents to be incorporated by reference therein and all
      exhibits thereto) proposed to be filed (at least 10 business days prior to
      such filing). The Issuers shall not file any Registration Statement or
      Prospectus or any amendments or supplements thereto in respect of which
      the Holders must be afforded an opportunity to review prior to the filing
      of such document if the the Holders of a majority of the Notes or such
      Participating Bro-

      underwriters, if any, shall reasonably object;

            (b) prepare and file with the SEC such amendments and post-effective
      amendments to each Notes Registration Statement as may be necessary to
      keep such Notes Registration Statement effective for the Effectiveness

      regulations promulgated thereunder applicable to it with respect to the
      disposition of all securities covered by each Notes Registration Statement
      during the Effectiveness Period or the Applicable Period, as the case may
      be, in accordance with the intended method or methods of distribution by
      the selling Holders thereof described in this Agreement (including sales
      by any Participating Broker-Dealer);

            (c) in the case of a Notes Shelf Registration, (i) notify each
      Holder of Registrable Notes, at least three business days prior to filing,
      that a Notes Shelf Registration Statement with respect to the Registrable
      Notes is being filed and advising such Holder that the distribution of
      Registrable Notes will be made in accordance with the method selected by
      the the Holders of a majority of the Notes; (ii) furnish to each Holder of
      Registrable Notes and to each underwriter of an underwritten offering of
      Registrable Notes, if any, without charge, as many copies of each
      Prospectus, including each preliminary Prospectus, and any amendment or
      supplement thereto and such other documents as such Holder or underwriter
      may reasonably request, in order to facilitate the public sale or other

      connection with the offering and sale of the Registrable Notes covered by
      the Prospectus or any amendment or supplement thereto;

            (d) in the case of a Notes Shelf Registration, use their respective
      reasonable best efforts to register or qualify the Registrable Notes under
      all applicable state securities or "blue sky" laws of such jurisdictions
      by the time the applicable Registration Statement is declared effective by
      the SEC as any Holder of Registrable Notes covered by a Notes Registration
      Statement and each underwriter of an underwritten offering of Registrable
      Notes shall reasonably request in advance of such date of effectiveness,
      and do any and all other acts and things which may be reasonably necessary
      or advisable to enable such Holder and underwriter to consummate the
      disposition in each such jurisdiction of such Registrable Notes owned by
      such Holder; provided that none of the Issuers shall be required to (i)
      qualify as a foreign corporation or as a dealer in securities in any
      jurisdiction where it would not otherwise be required to qualify but for
      this Section 3(d), (ii) file any general consent to service of process or

      2(b) or (2) a Prospectus contained in an Exchange Offer Registration
      Statement filed pursuant to Section 2(a) is required to be delivered under
      the 1933 Act by any Participating Broker-Dealer who seeks to sell Exchange
      Notes during the applicable period as provided in Section 3(t) hereof,
      notify each Holder of Registrable Notes, or such Participating
      Broker-Dealers, as the case may be, their counsel and the managing
      underwriters, if any, promptly and confirm such notice in writing (i) when
      a Notes Registration Statement has become effective and when any
      post-effective amendments and supplements thereto become effective, (ii)
      of any request by the SEC or any state securities authority for amendments
      and supplements to a Notes Registration Statement or Prospectus or for
      ad-

      ditional information after the Notes Registration Statement has become
      effective, (iii) of the issuance by the SEC or any state securities
      authority of any stop order suspending the effectiveness of a Notes
      Registration Statement or the initiation of any proceedings for that
      purpose, (iv) in the case of a Notes Shelf Registration, if, between the
      effective date of a Notes Registration Statement and the closing of any
      sale of Registrable Notes covered thereby, the representations and
      warranties of the Issuers contained in any underwriting agreement,
      securities sales agreement or other similar agreement, if any, relating to
      such offering cease to be true and correct in all material respects, (v)
      if the Issuers receive any notification with respect to the suspension of

      the happening of any event or the failure of any event to occur or the
      discovery of any facts or otherwise, during the period a Notes Shelf
      Registration Statement is effective which makes any statement made in such
      Notes Registration Statement or the related Prospectus untrue in any
      material respect or which causes such Notes Registration Statement or
      Prospectus to omit to state a material fact necessary to make the
      statements therein (in the case of any Prospectus, in the light of the
      circumstances under which they were made) not misleading and (vii) the
      Issuers' reasonable determination that a post-effective amendment to the
      Notes Registration Statement would be appropriate;

            (f) make every reasonable effort to obtain the withdrawal of any
      order suspending the effectiveness of a Notes Registration Statement as
      soon as practicable;

            (g) in the case of a Notes Shelf Registration, furnish to each

      out documents incorporated therein by reference or exhibits thereto,
      unless requested);

            (h) in the case of a Notes Shelf Registration, cooperate with the
      selling Holders of Registrable Notes to facilitate the timely preparation
      and delivery of certificates representing Registrable Notes to be sold and
      not bearing any restrictive legends; and cause such Registrable Notes to

      if any, may reasonably request at least two business days prior to the
      closing of any sale of Registrable Notes;

            (i) in the case of a Notes Shelf Registration or an Exchange Offer
      Registration, upon the occurrence of any circumstance contemplated by
      Section 3(e)(ii), 3(e)(iii), 3(e)(v), 3(e)(vi) or 3(e)(vii) hereof, except
      during Black Out Periods use their respective reasonable best efforts to
      prepare a supplement or post-effective amendment to a Notes Registration
      Statement or the related Prospectus or any document incorporated therein
      by reference or file any other required document so that, as thereafter
      delivered to the purchasers of the Registrable Notes, such Prospectus will
      not contain any untrue statement of a material fact or omit to state a
      material fact necessary to make the statements therein, in the light of
      the circumstances under which they were made, not misleading. The Issuers
      agree to notify each Holder to suspend use of the Prospectus as promptly
      as practicable after the occurrence of such an event, and each Holder
      hereby agrees to suspend use of the Prospectus until the Issuers have
      amended or supplemented the Prospectus to correct such misstatement or
      omission;

            (j) in the case of a Notes Shelf Registration, on or prior to the

      for the Exchange Notes or the Registrable Notes, as the case may be, in a
      form eligible for deposit with the Depositary;

            (l) cause the Indenture to be qualified under the Trust Indenture
      Act of 1939 (the "TIA") in connection with the registration of the
      Exchange Notes or Registrable Notes, as the case may be, cooperate with
      the Trustee and the Holders to effect such changes to the Indenture as may
      be required for the Indenture to be so qualified in accordance with the
      terms of the TIA and execute, and use their respective best efforts to
      cause the Trustee to execute, all documents as may be required to effect
      such changes, and all other forms and documents required to be filed with
      the SEC to enable the Indenture to be so qualified in a timely manner;

            (m) in the case of a Notes Shelf Registration, enter into such
      agreements (including underwriting agreements) as are customary in
      underwritten offerings and take all such other appropriate actions as are
      reasonably requested in order to expedite or facilitate the registration
      or the disposition of such Registrable Notes, and in such connection,
      whether or not an underwriting agreement is entered into and whether or
      not the registration is an underwritten registration: (i) make such
      representations and warranties to Holders of such Registrable Notes and
      the underwriters (if any), with respect to the business of the Issuers and
      any of their subsidiaries and the Notes Registration Statement, Prospectus
      and documents, if any, incorporated or deemed to be incorporated by
      reference therein, in each case, as are customarily made by issuers to
      underwriters in underwritten offerings, and confirm the same if and when
      requested; (ii) in the case of underwritten offerings obtain opinions of
      counsel to the Issuers 
<PAGE>
                                      -23-


      and updates thereof in form and substance reasonably satisfactory to the
      managing underwriters and the Holders of a majority in principal amount of
      the Registrable Notes being sold, addressed to each selling Holder and the

      requested in underwritten offerings and such other matters as may be
      reasonably requested by such Holders and underwriters; (iii) obtain "cold
      comfort" letters and updates thereof in form and substance reasonably
      satisfactory to the managing underwriters from the independent certified

      independent certified public accountants of any subsidiary of any of the
      Issuers or of any business acquired by any of the Issuers for which
      financial statements and financial data are, or are required to be,
      included in the Registration Statement), addressed to the selling Holders
      of Registrable Notes and to each of the underwriters, such letters to be
      in customary form and covering matters of the type customarily covered in
      "cold comfort" letters in connection with underwritten offerings and such
      other matters as reasonably requested by such selling Holders and
      underwriters; and (iv) if an underwriting agreement is entered into, the
      same shall contain indemnification provisions and procedures no less
      favorable than those set forth in Section 4 hereof (or such other
      provisions and procedures acceptable to Holders of a majority in aggregate
      principal amount of Registrable Notes covered by such Registration
      Statement and the managing underwriters or agents) with respect to all
      parties to be indemnified pursuant to said Section. The above shall be
      done at each closing under such underwriting agreement, or as and to the
      extent required thereunder;

            (n) if (1) a Notes Shelf Registration is filed pursuant to Section
      2(b) or (2) a Prospectus contained in an Exchange Offer Registration

      due diligence responsibilities, and cause the officers, directors and
      employees of the Issuers and any of their subsidiaries to supply all
      information in each case reasonably requested by any such Inspector in
      connection with such Notes Registration Statement. Records which the
      Issuers determine, in good faith, to be confidential and any Records which
      they notify the Inspectors are confidential shall not be disclosed by the
      Inspectors unless (i) the disclosure of such Records is necessary to avoid
      or correct a misstatement or omission in such Notes Registration
      Statement, (ii) the release of such Records is ordered pursuant to a
      subpoena or other order from a court of competent jurisdiction or (iii)
      the information in such Records has been made generally available to the
      public. Each selling Holder of such Registrable Notes and each such
      Participating Broker-Dealer will be required to agree that information
      obtained by it as a result of such inspections shall be deemed
      confidential and shall not be used by it as the basis for any market
      transactions in the securities of any of the Issuers unless and until such
      is made generally available to the public. Each selling Holder of such
      Registrable Notes and each such Participating Broker-Dealer will be
      required to further agree that it will, upon learning that disclosure of
      such Records is sought in a court of competent jurisdiction, give notice
      to the Issuers and allow the Issuers at their expense to undertake
<PAGE>
                                      -25-


      appropriate action to prevent disclosure of the Records deemed
      confidential;

            (o) comply with all applicable rules and regulations of the SEC and
      make generally available to its securityholders earnings statements
      satisfying the provisions of Section 11(a) of the 1933 Act and Rule 158
      thereunder (or any similar rule promulgated under the 1933 Act) no later
      than 45 days after the end of any 12-month period (or 90 days after the
      end of any 12-month period if such period is a fiscal year) (i) commencing
      at the end of any fiscal quarter in which Registrable Notes are sold to
      underwriters in a firm commitment or best efforts underwritten offering
      and (ii) if not sold to underwriters in such an offering, commencing on
      the first day of the first fiscal quarter of the Company and each Issuer
      after the effective date of a Registration Statement, which statements
      shall cover said 12-month periods;

            (p) upon consummation of an Exchange Offer or a Private Exchange,
      obtain an opinion of counsel to the Issuers addressed to the Trustee for
      the benefit of all Holders of Registrable Notes participating in the
      Exchange Offer or the Private Exchange, as the case may be, and which
      includes an opinion that (i) the Issuers have duly authorized, executed
      and delivered the Exchange Notes and Private Exchange Notes and the
      Indenture (and, to the extent applicable, the Guarantees), and (ii) each
      of the Exchange Notes or the Private Exchange Notes, as the case may be,
      and the Indenture (and, to the extent applicable, the Guarantees)
      constitute a legal, valid and binding obligation of the Issuers,
      enforceable against the Issuers in accordance with its respective terms
      (in each case, with customary exceptions and qualifications);

            (q) if an Exchange Offer or a Private Exchange is to be consummated,
      upon delivery of the Registrable Notes by Holders to the Issuers (or to
      such other Person as directed by the Issuers) in exchange for the Exchange
      Notes or the Private Exchange Notes, as the case may be, the Issuers shall
      mark, or cause to be marked, on such Registra-
<PAGE>
                                      -26-


      ble Notes delivered by such Holders that such Registrable Notes are being
      cancelled in exchange for the Exchange Notes or the Private Exchange
      Notes, as the case may be; in no event shall such Registrable Notes be
      marked as paid or otherwise satisfied;

            (r) cooperate with each seller of Registrable Notes covered by any
      Notes Registration Statement and each underwriter, if any, participating
      in the disposition of such Registrable Notes and their respective counsel
      in connection with any filings required to be made with the NASD;

            (s) use their respective best efforts to take all other steps
      necessary to effect the registration of the Registrable Notes covered by a
      Notes Registration Statement contemplated hereby;

            (t) (A) in the case of the Exchange Offer Registration Statement (i)
      include in the Exchange Offer Registration Statement a section entitled
      "Plan of Distribution," which section shall be reasonably acceptable to
      the Purchasers or another representative of the Participating
      Broker-Dealers, and which shall contain a summary statement of the
      positions taken or policies made by the staff of the SEC with respect to
      the potential "underwriter" status of any broker-dealer (a "Participating
      Broker-Dealer") that holds Registrable Notes acquired for its own account
      as a result of market-making activities or other trading activities and
      that will be the beneficial owner (as defined in Rule 13d-3 under the 1934
      Act) of Exchange Notes to be received by such broker-dealer in the
      Exchange Offer, whether such positions or policies have been publicly
      disseminated by the staff of the SEC or such positions or policies, in the
      reasonable judgment of the Purchasers or such other representative,
      represent the prevailing views of the staff of the SEC, including a
      statement that any such broker-dealer who receives Exchange Notes for
      Registrable Notes pursuant to the Exchange Offer may be deemed a statutory
      underwriter and must deliver a prospectus meeting the requirements of the
<PAGE>
                                      -27-


      1933 Act in connection with any resale of such Exchange Notes, (ii)
      furnish to each Participating Broker-Dealer who has delivered to the
      Issuers the notice referred to in Section 3(e), without charge, as many
      copies of each Prospectus included in the Exchange Offer Registration
      Statement, including any preliminary prospectus, and any amendment or
      supplement thereto, as such Participating Broker-Dealer may reasonably
      request, (iii) hereby consent to the use of the Prospectus forming part of
      the Exchange Offer Registration Statement or any amendment or supplement
      thereto, by any Person subject to the prospectus delivery requirements of
      the 1933 Act, including all Participating Broker-Dealers, in connection
      with the sale or transfer of the Exchange Notes covered by the Prospectus
      or any amendment or supplement thereto, (iv) use their respective
      reasonable best efforts to keep the Exchange Offer Registration Statement
      effective and to amend and supplement the Prospectus contained therein, in
      order to permit such Prospectus to be lawfully delivered by all Persons
      subject to the prospectus delivery requirements of the 1933 Act for such
      period of time as such Persons must comply with such requirements in order
      to resell the Exchange Notes; provided that such period shall not be
      required to exceed 180 days -------- (or such longer period if extended
      pursuant to the last sentence of Section 3 hereof) (the "Applicable
      Period"), and (v) include in the transmittal letter or similar
      documentation to be executed by an exchange offeree in order to
      participate in the Exchange Offer (x) the following provision:

      "If the exchange offeree is a broker-dealer holding Registrable Notes
      acquired for its own account as a result of market-making activities or
      other trading activities, it will deliver a prospectus meeting the
      requirements of the 1933 Act in connection with any resale of Exchange
      Notes received in respect of such Registrable Notes pursuant to the
      Exchange Offer."

      and (y) a statement to the effect that by a broker-dealer making the
      acknowledgment described in clause (x) and by 
<PAGE>
                                      -28-


      delivering a Prospectus in connection with the exchange of Registrable
      Notes, the broker-dealer will not be deemed to admit that it is an
      underwriter within the meaning of the 1933 Act; and

            (B) in the case of any Exchange Offer Registration Statement, the
      Issuers agree to deliver to the Purchasers on behalf of the Purchasers and
      the Participating Broker-Dealers upon consummation of the Exchange Offer
      (i) an opinion of counsel substantially in the form attached hereto as
      Exhibit A, (ii) an officers certificate containing certifications
      substantially similar to those set forth in Section 7(f) of the Purchase
      Agreement and such additional certifications as are customarily delivered
      in a public offering of debt securities and (iii) as well as upon the
      effectiveness of the Exchange Offer Registration Statement, a comfort
      letter, in each case, in customary form if permitted by Statement on
      Auditing Standards No. 72 of the American Institute of Certified Public
      Accountants.

            The Issuers may require each seller of Registrable Notes as to which
any registration is being effected to furnish to the Issuers such information
and representations regarding such seller and the proposed distribution of such
Registrable Notes, as the Issuers may from time to time reasonably request in
writing. The Issuers may exclude from such registration the Registrable Notes of
any seller who unreasonably fails to furnish such information within a
reasonable time after receiving such request.

            In the case of (1) a Notes Shelf Registration Statement or (2)
Participating Broker-Dealers who have notified the Issuer that they will be
utilizing the Prospectus contained in the Exchange Offer Registration Statement
as provided in Section 3(t) hereof, that are seeking to sell Exchange Notes and
are required to deliver Prospectuses, each Holder agrees that, upon receipt of
any notice from the Issuers of the happening of any event of the kind described
in Section 3(e)(ii), 3(e)(iii), 3(e)(v), 3(e)(vi) or 3(e)(vii) hereof, such
Holder will forthwith discontinue disposition of Registrable Notes pursuant to a
<PAGE>
                                      -29-


Notes Registration Statement until such Holder's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 3(i) hereof or until
it is advised in writing (the "Advice") by the Issuers that the use of the
applicable Prospectus may be resumed, and, if so directed by the Issuers, such
Holder will deliver to the Issuers (at the Issuers' expense) all copies in such
Holder's possession, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Registrable Notes or Exchange Notes,
as the case may be, current at the time of receipt of such notice. If the
Issuers shall give any such notice to suspend the disposition of Registrable
Notes or Exchange Notes, as the case may be, pursuant to a Notes Registration
Statement, the Issuer shall use their respective best efforts to file a
supplement or an amendment to the Notes Registration Statement and, in the case
of an amendment, have such amendment declared effective as soon as practicable
and shall extend the period during which such Notes Registration Statement shall
be maintained effective pursuant to this Agreement by the number of days in the
period from and including the date of the giving of such notice to and including
the date when the Issuer shall have made available to the Holders (x) copies of
the supplemented or amended Prospectus necessary to resume such dispositions or
(y) the Advice.

            4. Indemnification and Contribution. (a) Each of the Issuers,
jointly and severally, agrees to indemnify and hold harmless each Purchaser,
each Holder, each Participating Broker-Dealer, each underwriter who participates
in an offering of Registrable Notes, their respective affiliates, each Person,
if any, who controls any of such parties within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act and each of their respective directors,
officers, employees and agents, as follows:

            (i) against any and all loss, liability, claim, damage and expense
      whatsoever, joint or several, as incurred, arising out of any untrue
      statement or alleged untrue statement of a material fact contained in any
      Registration Statement (or any amendment thereto) covering Registrable
      Notes or Exchange Notes, including all documents incorpo-
<PAGE>
                                      -30-


      rated therein by reference, or the omission or alleged omission therefrom
      of a material fact required to be stated therein or necessary to make the
      statements therein not misleading or arising out of any untrue statement
      or alleged untrue statement of a material fact contained in any Prospectus
      (or any amendment or supplement thereto) or the omission or alleged
      omission therefrom of a material fact necessary in order to make the
      statements therein, in the light of the circumstances under which they
      were made, not misleading;

            (ii) against any and all loss, liability, claim, damage and expense
      whatsoever, joint or several, as incurred, to the extent of the aggregate
      amount paid in settlement of any litigation, or any investigation or
      proceeding by any court or governmental agency or body, commenced or
      threatened, or of any claim whatsoever based upon any such untrue
      statement or omission, or any such alleged untrue statement or omission;
      provided that (subject to Section 4(c) below) any such settlement is
      effected with the prior written consent of the Company; and

            (iii) against any and all expenses whatsoever, as incurred
      (including reasonable fees and disbursements of counsel chosen by such
      Purchaser, such Holder, such Participating Broker-Dealer or any
      underwriter (except to the extent otherwise expressly provided in Section
      4(c) hereof)), reasonably incurred in investigating, preparing or
      defending against any litigation, or any investigation or proceeding by
      any court or governmental agency or body, commenced or threatened, or any
      claim whatsoever based upon any such untrue statement or omission, or any
      such alleged untrue statement or omission, to the extent that any such
      expense is not paid under subparagraph (i) or (ii) of this Section 4(a);

provided that this indemnity does not apply to any loss, liability, claim,
damage or expense to the extent arising out of an untrue statement or omission
or alleged untrue statement or omission (i) made in reliance upon and in
conformity with written information furnished to the Issuers by such Purchaser,
<PAGE>
                                      -31-


such Holder, such Participating Broker-Dealer or any underwriter in writing
expressly for use in the Registration Statement (or any amendment thereto) or
any Prospectus (or any amendment or supplement thereto) or (ii) contained in any
preliminary prospectus if the Purchasers, such Holder, such Participating
Broker-Dealer or such underwriter failed to send or deliver a copy of the
Prospectus (in the form it was first provided to such parties for confirmation
of sales) to the Person asserting such losses, claims, damages or liabilities on
or prior to the delivery of written confirmation of any sale of securities
covered thereby to such Person in any case where such delivery is required by
the 1933 Act and a court of competent jurisdiction in a judgment not subject to
appeal or final review shall have determined that such Prospectus would have
corrected such untrue statement or omission. Any amounts advanced by an
indemnifying party to an indemnified party pursuant to this Section 4 as a
result of such losses shall be returned to such indemnifying party if it shall
be finally determined by such a court in a judgment not subject to appeal or
final review that such indemnified party was not entitled to indemnification by
such indemnifying party.

            (b) Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Issuers, the Purchasers, each underwriter who participates in
an offering of Registrable Notes and the other selling Holders and each of their
respective directors, officers (including each officer of each of the Issuers
who signed the Registration Statement), employees and agents and each Person, if
any, who controls each of the Issuers, the Purchasers, any underwriter or any
other selling Holder within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act, against any and all loss, liability, claim, damage and
expense whatsoever described in the indemnity contained in Section 4(a) hereof,
as incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto) in
reliance upon and in conformity with written information furnished to the
Issuers by such selling Holder expressly for use in the Registration Statement
(or any 
<PAGE>
                                      -32-


amendment thereto), or any such Prospectus (or any amendment or supplement
thereto); provided, however, that in the case of a Notes Shelf Registration
Statement, no such Holder shall be liable for any claims hereunder in excess of
the amount of net proceeds received by such Holder from the sale of Registrable
Notes pursuant to such Notes Shelf Registration Statement.

            (c) Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement. In the case of
parties indemnified pursuant to Section 4(a) above, counsel to the indemnified
parties shall be selected by Merrill Lynch, and, in the case of parties
indemnified pursuant to Section 4(b) above, counsel to the indemnified parties
shall be selected by the Issuers. Notwithstanding the foregoing sentence, in
case any such action is brought against any indemnified party, and it notifies
the indemnifying party of the commencement thereof, the indemnifying party will
be entitled to participate therein and, to the extent it may wish, jointly with
any other indemnifying party similarly notified, unless such indemnified party
shall have one or more legal defenses available to it which are not available to
the indemnifying party to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party. After notice from the indemnifying party
to such indemnified party of its election as aforesaid to assume the defense
thereof and approval by such indemnified party of counsel appointed to defend
such action, the indemnifying party will not be liable to such indemnified party
under this Section 4 for any legal or other expenses other than reasonable costs
of investigation, subsequently incurred by such indemnified party in connection
with the defense thereof. An indemnifying party may participate at its own
expense in the defense of any such action; provided, however, that counsel to
the indemnifying party shall not (except with the consent of the indemnified
<PAGE>
                                      -33-


party) also be counsel to the indemnified party. In no event shall the
indemnifying parties be liable for fees and expenses of more than one counsel
(in addition to any local counsel) separate from their own counsel for all
indemnified parties in connection with any one action or separate but similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances. No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 4 (whether or not the indemnified parties are
actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

            (d) If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 4(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.

            (e) In order to provide for just and equitable contribution in
circumstances under which any of the indemnity provisions set forth in this
Section 4 is for any reason held to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Issuers, the Purchasers
<PAGE>
                                      -34-


and the Holders shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by such indemnity agreement
incurred by the Issuers, the Purchasers and the Holders, as incurred; provided
that no Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person
that was not guilty of such fraudulent misrepresentation. As between the
Issuers, the Purchasers and the Holders, such parties shall contribute to such
aggregate losses, liabilities, claims, damages and expenses of the nature
contemplated by such indemnity agreement in such proportion as shall be
appropriate to reflect the relative fault of the Issuers, on the one hand, and
the Purchasers and the Holders, on the other hand, with respect to the
statements or omissions which resulted in such loss, liability, claim, damage or
expense, or action in respect thereof, as well as any other relevant equitable
considerations. The relative fault of the Issuers, on the one hand, and of the
Purchasers and the Holders, on the other hand, shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Issuers, on the one hand, or by or on
behalf of the Purchasers or the Holders, on the other, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The Issuers, the Purchasers and the Holders of the
Registrable Notes agree that it would not be just and equitable if contribution
pursuant to this Section 4 were to be determined by pro rata allocation or by
any other method of allocation that does not take into account the relevant
equitable considerations. For purposes of this Section 4, each affiliate of the
Purchasers or Holder, and each director, officer, employee, agent and Person, if
any, who controls a Purchasers or Holder or such affiliate within the meaning of
Section 15 of the 1933 Act shall have the same rights to contribution as such
Purchaser or Holder, and each director of each of the Issuers, each officer of
each of the Issuers who signed the Registration Statement, and each Person, if
any, who controls each of the Issuers within the meaning of Section 15 
<PAGE>
                                      -35-


of the 1933 Act shall have the same rights to contribution as each of the
Issuers.

            5. Participation in Underwritten Registrations. No Holder may
participate in any underwritten registration hereunder unless such Holder (a)
agrees to sell such Holder's Registrable Notes on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all reasonable questionnaires,
powers of attorney, indemnities, underwriting agreements, lock-up letters and
other documents reasonably required under the terms of such underwriting
arrangements.

            6. Selection of Underwriters. The Holders of Registrable Securities
covered by the Notes Shelf Registration Statement who desire to do so may sell
the securities covered by such Notes Shelf Registration in an underwritten
offering. In any such underwritten offering, the underwriter or underwriters and
manager or managers that will administer the offering will be selected by the
Holders of a majority in aggregate principal amount of the Registrable Notes
included in such offering; provided that such underwriters and managers must be
satisfactory to the Issuers.

            7. Miscellaneous.

            (a) Rule 144 and Rule 144A. For so long as the Issuers are subject
to the reporting requirements of Section 13 or 15 of the 1934 Act and any
Registrable Notes remain outstanding, the Issuers covenant that they will file
the reports required to be filed by it under the 1933 Act and Section 13(a) or
15(d) of the 1934 Act and the rules and regulations adopted by the SEC
thereunder, that if they cease to be so required to file such reports, they will
upon the request of any Holder of Registrable Notes (a) make publicly available
such information as is necessary to permit sales pursuant to Rule 144 under the
1933 Act, (b) deliver such information to a prospective purchaser as is
necessary to permit sales pursuant to Rule 144A under the 1933 Act and they will
take such further action as any Holder of Registrable Notes may reasonably
request, and (c) 
<PAGE>
                                      -36-


take such further action that is reasonable in the circumstances, in each case,
to the extent required from time to time to enable such Holder to sell its
Registrable Notes without registration under the 1933 Act within the limitation
of the exemptions provided by (i) Rule 144 under the 1933 Act, as such rule may
be amended from time to time, (ii) Rule 144A under the 1933 Act, as such rule
may be amended from time to time, or (iii) any similar rules or regulations
hereafter adopted by the SEC. Upon the request of any Holder of Registrable
Notes, the Issuers will deliver to such Holder a written statement as to whether
it has complied with such requirements.

            (b) No Inconsistent Agreements. The Issuers have not entered into
nor will the Issuers on or after the date of this Agreement enter into any
agreement which is inconsistent with the rights granted to the Holders of
Registrable Notes in this Agreement or otherwise conflicts with the provisions
hereof. The rights granted to the Holders hereunder do not in any way conflict
with and are not inconsistent with the rights granted to the holders of any of
the Issuers' other issued and outstanding securities under any such agreements.

            (c) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Issuers have obtained the written consent of Holders
of at least a majority in aggregate principal amount of the outstanding
Registrable Notes affected by such amendment, modification, supplement, waiver
or departure; provided no amendment, modification or supplement or waiver or
consent to the departure with respect to the provisions of Section 4 hereof
shall be effective as against any Holder of Registrable Notes unless consented
to in writing by such Holder of Registrable Notes; provided, further, that this
Section 7(c) shall not prevent the Company, without the consent of any Holder,
from executing any supplement or amendment to this Agreement the sole purpose of
which is to add any Guarantor as a party and as an Issuer under the terms of
this Agreement.
<PAGE>
                                      -37-


            (d) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Issuers by means of a notice given in accordance with the provisions of this
Section 7(d), which address initially is, with respect to the Purchasers, the
address set forth in the Purchase Agreement; and (ii) if to the Issuers,
initially at the Issuers' address set forth in the Purchase Agreement and
thereafter at such other address, notice of which is given in accordance with
the provisions of this Section 7(d).

            All such notices and communications shall be deemed to have been
duly given: at the time delivered by hand, if personally delivered; five
business days after being deposited in the mail, postage prepaid, if mailed;
when answered back, if telexed; when receipt is acknowledged, if telecopied; and
on the next business day, if timely delivered to an air courier guaranteeing

                           Form of Opinion of Counsel

            1. Each of the Exchange Offer Registration Statement and the
Prospectus (other than the financial statements, notes or schedules thereto and
other financial and statistical data and supplemental schedules included or
referred to therein or omitted therefrom and the Form T-1, as to which such
counsel need express no opinion), complies as to form in all material respects
with the applicable requirements of the 1933 Act and the applicable rules and
regulations promulgated under the 1933 Act.

            2. In the course of such counsel's review and discussion of the
contents of the Exchange Offer Registration Statement and the Prospectus with
certain officers and other representatives of the Issuers and representatives of
the independent certified public accountants of the Issuers, but without
independent check or verification or responsibility for the accuracy,
completeness or fairness of the statements contained therein, on the basis of
the foregoing (relying as to materiality to a large extent upon representations
and opinions of officers and other representatives of the Issuers), no facts
have come to such counsel's attention which cause such counsel to believe that
the Exchange Offer Registration Statement (other than the financial statements,
notes and schedules thereto and other financial and statistical information
contained or referred to therein and the Form T-1, as to which such counsel need
express no belief), at the time the Exchange Offer Registration Statement became
effective and as of the date of this opinion, contained or contains an untrue
statement of a material fact or omitted or omits to state a material fact
required to be stated therein or necessary to make the statements contained
therein not misleading, or that the Prospectus (other than the financial
statements, notes and schedules thereto and other financial and statistical
information contained or referred to therein, as to which such counsel need
express no be-
<PAGE>

lief) contained or contains any untrue statement of a material fact or omitted
or omits to state a material fact necessary to make the statements contained
therein, in the light of the circumstances under which they were made, not
misleading.

      2. Registration Rights.

            2.1. Demand Registration. (a) Request for Registration. At any time
on or after a Triggering Event, Holders owning, individually or in the
aggregate, at least the Requisite Shares may make two written requests for
registration under the Securities Act of their Company Registrable Securities (a
"Demand Registration"). Any such request will specify the number of Company
Registrable Securities proposed to be sold and will also specify the intended
method of disposition thereof. Subject to the other provisions of this Section
2.1, the Company shall give written notice of such registration request within
10 days after the receipt thereof to all other Holders. Within 30 days after
receipt of such notice by any Holder, such Holder may request in writing that
its Company Registrable Securities be included in such registration and the
Company shall include in the Demand Registration the Company Registrable
Securities of any such selling Holder requested to be so included. Each such
request by such other selling Holders shall specify the number of Company
Registrable Securities proposed to be sold and the intended method of
disposition thereof. Upon a demand, the Company will (i) prepare, file with the
SEC and use its reasonable best efforts to cause to become effective within 120
days of such demand a Registration Statement in respect of all the Company
Registrable Securities which Holders request for inclusion therein; provided
that if such demand occurs during a Black Out Period or a period (not to exceed
180 days) during which the Company is prohibited or restricted from issuing or
selling Common Stock pursuant to any underwriting or purchase agreement relating
to an underwritten public offering of Common Stock or securities convertible
into or exchangeable for Common Stock under Rule 144A or registered under the
Security Act or any agreement with a securityholder of the Company exercising
registration rights pursuant to an agreement in existence on the date hereof (a
"Lock Up Period"), the Company shall not be required to notify the Holders of
such demand or file such Registration Statement prior to the end of the Black
Out Period or Lock Up Period, as the case may be, in which event, the Company
will use its best efforts to cause such Registration Statement to become
effective no later than 45 days after the end of the Black Out Period or Lock Up
Period, as the case may be, and (ii) keep such Registration Statement
continuously effective for the shorter of (a) 180 days (the "Effectiveness
Period") and (b) such period of time as all of the Company Registrable
Securities included in such
<PAGE>

                                      -11-


Registration Statement have been sold thereunder; provided, however, that the
Company may postpone the filing period, suspend the effectiveness of any
registration, suspend the use of any Prospectus and shall not be required to
amend or supplement the Registration Statement, any related Prospectus or any
document incorporated therein by reference (other than an effective registration
statement being used for an underwritten offering) in the event that, and for a
period, in the case of any particular Demand Registration, not to exceed an
aggregate of 45 days ("Black Out Period") if (i) an event or circumstance occurs
and is continuing as a result of which the Registration Statement, any related
Prospectus or any document incorporated therein by reference as then amended or
supplemented would, in the Company's good faith judgment, contain an untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein (in the case of any Prospectus, in the light of
the circumstances under which they were made), not misleading, and (ii)(A) the
Company determines in its good faith judgment that the disclosure of such event
at such time would have a material adverse effect on the business, operations or
prospects of the Company or (B) the disclosure otherwise relates to a material
business transaction which has not yet been publicly disclosed; provided,
further, that the Effectiveness Period shall be extended by the number of days
in any Black Out Period. Subject to Section 2.1(b), the Company shall only be
required to register Registrable Securities pursuant to this Section 2.1 once.

            In the event of the occurrence of any Black Out Period during an
Effectiveness Period or Lock Up Period, the Company will promptly notify the
Holders of Company Registrable Securities thereof in writing.

            (b) Effective Registration. A registration will not be deemed to
have been effected as a Demand Registration, and thereby satisfy the obligation
hereunder, unless it has been declared effective by the SEC and the Company has
complied in all material respects with its obligations under this Agreement with
respect thereto; provided that if, after it has become effective, the offering
of Company Registrable Securities pursuant to such registration is or becomes
the subject of any stop order, injunction or other order or requirement of the
SEC or any other governmental or administrative agency, or if any court prevents
or otherwise limits the sale of Company Registrable Securities pursuant to the
registration (for any reason other than the act or omissions of the Holders) for
the period of time contemplated hereby, such registration will be deemed not to
have been effected. If (i) a registration requested
<PAGE>

                                      -12-


pursuant to this Section 2.1 is deemed not to have been effected or (ii) the
registration requested pursuant to this Section 2.1 does not remain effective
for the Effectiveness Period, then the Company shall continue to be obligated to
effect an additional registration pursuant to this Section 2.1. The Holders of
Company Registrable Securities shall be permitted to withdraw all or any part of
the Company Registrable Securities from a Demand Registration at any time prior
to the effective date of such Demand Registration. If at any time a Registration
Statement is filed with the SEC pursuant to a Demand Registration, and
subsequently a sufficient number of the Company Registrable Securities are
withdrawn from the Demand Registration so that such Registration Statement does
not cover that number of Company Registrable Securities at least equal to 25% of
the Shares originally issued to the LLC, the Holders who have not withdrawn
their Company Registrable Securities shall have the opportunity to include an
additional number of Company Registrable Securities in the Demand Registration
so that such Registration Statement covers that number of Company Registrable
Securities at least equal to 25% of the Shares originally issued to the LLC. If
an additional number of Company Registrable Securities is not so included, the
Company may withdraw the Registration Statement. Such withdrawn Registration
Statement will not count as a Demand Registration and the Company shall continue
to be obligated to effect a registration pursuant to this Section 2.1; provided
the Holders that requested withdrawal shall be obligated to reimburse the
Company for all customary and reasonable out-of-pocket expenses incurred by it
in performing its obligations hereunder with respect to such withdrawn
Registration Statement.

            (c) Priority in Demand Registrations Pursuant to Section 2.1. If a
Demand Registration pursuant to this Section 2.1 involves an underwritten
offering and the lead managing underwriter advises the Company in writing that,
in its view, the number of Company Registrable Securities requested by the
Holders to be included in such registration, together with any other securities
permitted to be included in such registration pursuant to Section 8(c) hereof
exceeds the number which, can be sold without adversely affecting the offering:
first, the securities other than the Company Registrable Securities of the
Holders included in such registration shall be reduced in their entirety before
any reduction of Company Registrable Securities; and second, to the extent the
reduction set forth in the immediately preceding clause is insufficient to
reduce the number of securities requested for inclusion in such registration to
a number, which, in the view of such lead managing underwriter, can be sold
without adversely affecting the offer-

<PAGE>

                                      -13-


ing, the number of such Company Registrable Securities to be included in such
registration shall be allocated pro rata among all requesting Holders on the
basis of the relative number of Company Registrable Securities then held by each
such Holder (provided that any Company Registrable Securities thereby allocated
to any such Holder that exceed such Holder's request shall be reallocated among
the remaining requesting Holders in like manner). In the event that the number
of Company Registrable Securities requested to be included in such registration
is less than the number which, in the view of the lead managing underwriter, can
be sold without adversely affecting the offering, the Company may include in
such registration the securities the Company or any other Person proposes to
sell up to the number of securities that, in the view of the lead managing
underwriter, can be sold without adversely affecting the offering.

            (d) Selection of Underwriter. If the Holders so elect, the offering
of such Company Registrable Securities pursuant to a Demand Registration shall
be in the form of an underwritten offering. The Company shall select one or more
nationally recognized firms of investment bankers (to whom a majority of Holders
making such Demand Registration shall not have reasonably objected) to act as
the managing underwriter or underwriters (and if more than one Managing
Underwriter is selected, the Company shall also name the lead managing
underwriter) in connection with such offering and shall select any additional
investment bankers and managers to be used in connection with the offering.

            (e) Expenses. The Company will pay all Registration Expenses in
connection with the registration requested pursuant to Section 2.1(a). Each
Holder shall pay all underwriting discounts and commissions and transfer taxes,
if any, relating to the sale or disposition of such Holder's Company Registrable
Securities pursuant to a registration statement requested pursuant to this
Section 2.1.

            (f) Ability of LLC Shareholders to Effect Rights. In the event that
the Initial Public Equity Offering occurs but a Liquidation Event has not
occurred, Holders of Registrable Securities of the LLC will be entitled to the
rights and privileges pertaining to Company Registrable Securities in accordance
with each such Holder's Percentage Interest (as defined in the Purchase
Agreement) with respect to the Company Registrable Securities held by the LLC
notwithstanding that a Liquidation Event has not occurred and Holders may cause
the LLC to
<PAGE>

                                      -14-


deliver Company Registrable Securities for inclusion in a Demand Registration
pursuant to this Section 2.1.

            2.2. Piggy-Back Registration. If at any time either of the Issuers
proposes to file a Registration Statement under the Securities Act with respect
to an offering by such Issuer for its own account or for the account of any of
its respective securityholders of any class of Common Stock (other than (i) a
registration statement on Form S-8, S-4 or F-4 (or any substitute form that may
be adopted by the SEC), (ii) a registration statement filed in connection with
an offer or offering of securities solely to such Issuer's existing
securityholders or (iii) a Demand Registration), then such Issuer shall give
written notice of such proposed filing to the Holders of Registrable Securities
as soon as practicable (but in no event less than 20 Business Days before the
anticipated filing date), and such notice shall offer such Holders the
opportunity to register such number of Registrable Securities as each such
Holder may request (which request shall specify the Registrable Securities
intended to be disposed of by such Holder (a "Piggy-Back Registration"). Such
Issuer shall use its reasonable best efforts to cause the managing underwriter
or underwriters of such proposed underwritten offering to permit the Registrable
Securities requested to be included in a Piggy-Back Registration to be included
on the same terms and conditions as any similar securities of such Issuer or any
other securityholder included therein and to permit the sale or other
disposition of such Registrable Securities in accordance with the intended
method of distribution thereof, provided, however, in no event shall such Issuer
be required to reduce the number of securities proposed to be sold by such
Issuer or alter the terms of the securities proposed to be sold by such Issuer
in order to induce the managing underwriter or underwriters to permit
Registrable Securities to be included. Any Holder shall have the right to
withdraw its request for inclusion of its Registrable Securities in any
Registration Statement pursuant to this Section 2.2 by giving written notice to
such Issuer of its request to withdraw prior to the effectiveness of the
Registration Statement. An Issuer may withdraw a Piggy-Back Registration at any
time prior to the time it becomes effective; provided that such Issuer shall
give prompt notice thereof to participating Holders. The Company will pay all
Registration Expenses in connection with each registration of Registrable
Securities requested pursuant to this Section 2.2, and each Holder shall pay all
underwriting discounts and commissions and transfer taxes, if any, relating to
the sale or disposition of such Holder's Registrable Securities pursuant to a
registration statement effected pursuant to this Section 2.2.
<PAGE>

                                      -15-


            No registration effected under this Section 2.2, and no failure to
effect a registration under this Section 2.2, shall relieve an Issuer of its
obligation to effect a registration upon the request of Holders pursuant to
Section 2.1, and no failure to effect a registration under this Section 2.2 and
to complete the sale of Registrable Securities in connection therewith shall
relieve an Issuer of any other obligation under this Agreement.

            2.3. Reduction of Offering. (a) If the lead managing underwriter of
any underwritten offering described in Section 2.2 has informed, in writing, the
Holders of the Registrable Securities requesting inclusion in such offering that
it is its view that the total number of securities which an Issuer, the Holders
and any other Persons desiring to participate in such registration intend to
include in such offering is such as to materially and adversely affect the
success of such offering, including the price at which such securities can be
sold, then the number of Registrable Securities to be offered for the account of
such Holders and the number of such securities to be offered for the account of
all such other Persons (other than the Company) participating in such
registration shall be reduced or limited pro rata in proportion to the
respective number of securities requested to be registered to the extent
necessary to reduce the total number of securities requested to be included in
such offering to the number of securities, if any, recommended by such lead
managing underwriter; provided that if such offering is effected for the account
of any securityholder of the Company other than the Holders (either directly or
through the LLC), pursuant to the demand registration rights of any such
securityholder, then the number of securities to be offered for the account of
the Company (if any) and the Holders (but not such securityholders who have
exercised their demand registration rights) shall be reduced or limited pro rata
in proportion to the respective number of securities requested to be registered
to the extent necessary to reduce the total number of securities requested to be
included in such offering to the number of securities, if any, recommended by
such lead managing underwriter.

            (b) If the lead managing underwriter of any underwritten offering
described in Section 2.2 notifies the Holders requesting inclusion of
Registrable Securities in such offering, that the kind of securities that such
Holders, the Company and any other Persons desiring to participate in such
registration intend to include in such offering is such as to materially and
adversely affect the success of such offering, (x) the Registrable Securities to
be included in such offering shall be
<PAGE>

                                      -16-


reduced as described in clause (i) above or (y) if a reduction in the
Registrable Securities pursuant to clause (i) above would, in the judgment of
the lead managing underwriter, be insufficient to substantially eliminate the
adverse effect that inclusion of the Registrable Securities requested to be
included would have on such offering, such Registrable Securities will be
excluded from such offering.

            (c) If, as a result of the proration provisions of this Section 2.3,
any Holder shall not be entitled to include all Registrable Securities in a
Piggy-Back Registration that such Holder has requested to be included, such
Holder may elect to withdraw his request to include Registrable Securities in
such registration (a "Withdrawal Election"); provided that a Withdrawal Election
shall be made prior to the effectiveness of the Registration Statement and shall
be irrevocable and, after making a Withdrawal Election, a Holder shall no longer
have any right to include Registrable Securities in the registration as to which
such Withdrawal Election was made.

            (d) Holders of Registrable Securities of the LLC will be entitled to
the rights and privileges pertaining to Company Registrable Securities in
accordance with each such Holder's Percentage Interest with respect to the
Company Registrable Securities held by the LLC notwithstanding that a
Liquidation Event has not occurred and Holders may cause the LLC to deliver
Company Registrable Securities for inclusion in a Piggy-Back Registration
pursuant to this Section 2.3.

      3. Transfers.

            3.1. Generally. All Shares and Registrable Securities at any time
and from time to time outstanding shall be held subject to the conditions and
restrictions set forth in this Section 3. All shares of Capital Stock of the
Issuers now or hereafter beneficially owned by the Shareholders and each of
their Affiliates shall be held subject to the conditions and restrictions set
forth in this Section 3. Each Holder of Shares and Registrable Securities and
each of the Shareholders by executing this Agreement or by accepting a
certificate representing Capital Stock or other indicia of ownership therefor
from an Issuer agree with each Issuer to such conditions and restrictions.

            3.2. Restrictions on Transfer. (a) The LLC shall keep, at the office
or agency maintained by the LLC for such purpose in the City of New York,
Borough of Manhattan, a register or registers in which, subject to such
reasonable regula-
<PAGE>

                                      -17-


tions as it may prescribe, the LLC shall provide for the registration of, and
registration of transfer of, Shares of the LLC as provided in this Article. The
Company shall at all times maintain appropriate and customary arrangements
providing for the registration of, and registration of transfer of, Shares as
provided in this Article. Each person designated by an Issuer from time to time
as a person authorized to register the transfer and exchange of the Shares of
such Issuer is hereinafter called, individually and collectively, the "Transfer
Agent" and shall be required to agree to Sections 3.2 through 3.5 hereof;
provided, however, that Banco Itau shall not be required to agree to Section 3.5
to the extent such Section shall be inapplicable to Shares of the Company. The
LLC has initially appointed Chase Mellon Shareholder Services as Transfer Agent
with respect to Shares of the LLC. The Company has initially appointed Banco
Itau S.A. as Transfer Agent with respect to Shares of the Company. The Company
shall, promptly following the execution of this Agreement, duly register this
Agreement and shall notify Banco Itau thereof. Upon written notice by any Issuer
to any acting Transfer Agent, such Issuer may appoint a successor Transfer Agent
for such purposes.

            (b) Any Transfer made in violation of this Agreement by a
Shareholder or any of its Affiliates shall be deemed null and void and shall not
be recorded as a transfer upon the transfer books of the applicable Issuer. Each
certificate representing shares of Common Stock held by a Shareholder and each
of its Affiliates shall contain conspicuous notation on such certificate
indicating that the transfer of such shares is subject to the terms and
restrictions of this Agreement, and each of the Shareholders hereby consents to
the placement of such legend on the certificate or certificates representing the
shares of Common Stock beneficially owned by such party.

            3.3. Tag-Along Rights. (a) In the event of any proposed direct or
indirect Transfer of beneficial ownership of Shares (whether now or hereafter
issued) by a Shareholder (the "Proposed Seller") or any of its Affiliates in any
transaction or series of related transactions (including any proposed direct or
indirect transfer of Common Stock by the LLC for the capital account of any
Shareholder or any Affiliate having an interest in the LLC) to any Person (other
than an Excluded Transfer or a Transfer of beneficial ownership of Common Stock
by the LLC to the Member of the LLC whose capital account is at such time
credited with such Common Stock upon the occurrence of a Liquidation Event)
(such other Person being hereinafter referred to as the "Proposed Purchaser") at
any time prior to the Triggering Date, the holders of Shares and Registrable Se-

<PAGE>

                                      -18-


curities shall have the irrevocable right, but not the obligation (the
"Tag-Along Right"), to require the Proposed Purchaser to purchase from each of
them up to such number of Shares and Registrable Securities (the "Included
Securities") determined in accordance with Section 3.3(c). The Proposed Seller
shall give written notice (a "Transfer Notice") at least 30 days prior to the
date of the proposed Transfer (the "Proposed Transfer Date") to the holders of
Shares and Registrable Securities stating (i) the name and address of the
Proposed Purchaser, (ii) the proposed amount of consideration, terms and
conditions of payment offered by such Proposed Purchaser (if the proposed
consideration is not cash, the Transfer Notice shall describe the terms of the
proposed consideration) and the time and place of the closing for the proposed
Transfer, (iii) the number of shares of Common Stock and other securities
proposed to be directly or indirectly Transferred by the Proposed Seller and/or
its Affiliates and (iv) either that the Proposed Purchaser has been informed of
the Tag-Along Right and has agreed to purchase Shares and Registrable Securities
in accordance with the terms hereof or that the Proposed Seller or any of its
Affiliates will make such purchase. The Tag-Along Right shall be exercised by
any or all of the holders of Shares and Registrable Securities by giving written
notice to the Issuers of the Shares or Registrable Securities proposed to be
sold ("Tag-Along Notice"), within 15 days of receipt of the Transfer Notice,
indicating its election to exercise the Tag-Along Right (the "Participating
Holders"). The Tag-Along Notice shall state the amount of Shares and Registrable
Securities that such holder proposes to include in such Transfer to the Proposed
Purchaser. Failure by any holder to give such notice within the 15-day period
shall be deemed an election by such holder not to sell its Shares and
Registrable Securities pursuant to that Transfer. The closing with respect to
any sale to a Proposed Purchaser pursuant to this Section shall be held at the
time and place specified in the Transfer Notice but in any event within 60 days
of the Proposed Transfer Date; provided that if through the exercise of
reasonable efforts the Proposed Seller or any of its Affiliates is unable to
cause such transaction to close within 60 days, such period may be extended for
such reasonable period of time as may be necessary to close such transaction.
Consummation of the sale of Common Stock or other securities by the Proposed
Seller and/or its Affiliates to a Proposed Purchaser shall be conditioned upon
consummation of the sale by each Participating Holder to such Proposed Purchaser
(or the Proposed Seller) of the Included Securities, if any.

                                      -19-


            (b) In the event that the Proposed Purchaser does not purchase
Included Securities from the holders on the same terms and conditions as
purchased from the Proposed Seller and its Affiliates, then the Proposed Seller
or such Affiliate shall purchase, or cause another Person to purchase, such
Included Securities if the Transfer occurs.

            (c) Each holder of Shares and Registrable Securities shall have the
right to require the Proposed Purchaser to purchase from such holder up to a
percentage of the number of Shares and Registrable Securities owned by such
holder equaling the percentage derived by dividing the total number of shares of
Common Stock that the Proposed Seller and its Affiliates propose to directly or
indirectly Transfer by the total number of shares of Common Stock at the time
beneficially owned by the Proposed Seller and its Affiliates; provided that in
the event of any proposed Transfer, either at a time or as a result of which
there would result a Change of Control, each holder of Shares and Registrable
Securities shall have the right to require the Proposed Purchaser to purchase
all of the Shares and Registrable Securities owned by such holder.

            (d) Any Shares and/or Registrable Securities purchased from the
Participating Holders pursuant to this Section 3.3 shall be paid for in the same
type of consideration and at the same price per share of Common Stock and upon
the same terms and conditions of such proposed Transfer of Common Stock by the
Proposed Seller and/or any of its Affiliates. If the Registrable Securities to
be purchased include securities or property other than Common Stock, the price
to be paid for such securities or property shall be the same price per share or
other denomination paid by the Proposed Purchaser for like securities purchased
from the Proposed Seller and/or its Affiliates or, if like securities are not
purchased from the Proposed Seller and/or its Affiliates by the Proposed
Purchaser, the Fair Market Value of such securities. The Proposed Seller shall
arrange for payment directly by the Proposed Purchaser to each Participating
Holder, upon delivery of the certificate or certificates representing the Shares
and/or Registrable Securities duly endorsed for transfer, together with such
other documents as the Proposed Purchaser may reasonably request.

            (e) If at the end of 60 days following the Proposed Transfer Date,
or as otherwise extended pursuant to the provisions of Section 3.3(a), the sale
of Common Stock by the Proposed Seller and/or its Affiliates and the sale of the
Included Securities have not been completed in accordance with the terms of the
Proposed Purchaser's offer, all certificates represent-
<PAGE>

                                      -20-


ing the Included Securities shall be returned to the Participating Holders, and
all the restrictions on Transfer contained in this Agreement with respect to
Common Stock beneficially owned by the Proposed Seller and its Affiliates shall
remain in effect.

            3.4. Obligation to Sell. If at any time prior to the Triggering Date
the Shareholders and/or any of their Affiliates determine to sell all of the
Common Stock of the Company then beneficially owned by the Shareholders and
their Affiliates to a Person other than an Affiliate of a Shareholder, the
Shareholders shall have the right to require the Holders of Registrable
Securities to sell such Registrable Securities to such transferee; provided that
(a) the consideration to be received by the Shareholders of Registrable
Securities shall be the same type of consideration received by the Shareholders
and their Affiliates and, in any event, shall be cash and/or securities
registered under the Securities Act and listed on a national securities exchange
or authorized for quotation on the Nasdaq National Market System, (b) after
giving effect to such transaction, the Shareholders and their Affiliates shall
not beneficially own, directly or indirectly, any Capital Stock or rights to
purchase Capital Stock of the Company and (c) the foregoing provisions shall not
apply to sales of Common Stock by the Company in a registered public offering
under the Securities Act or an offering pursuant to Rule 144A. Any Registrable
Securities purchased from the Holders pursuant to this Section 3.4 shall be paid
for at the same price per share of Common Stock and upon the same terms and
conditions of such proposed transfer of Common Stock by the Shareholders and
their Affiliates. If the Registrable Securities to be purchased include
securities other than Common Stock, the price to be paid for such securities
shall be the same price per share or other denomination paid by the Proposed
Purchaser for like securities purchased from the Shareholders and their
Affiliates or, if like securities are not purchased from the Shareholders and
their Affiliates, the Fair Market Value of such securities.

            3.5. Registration of Transfers or Exchanges.

            (a) Transfer or Exchange of Definitive Certificates. When Definitive
Certificates are presented to the Transfer Agent with a request from the holder:

      (i)   to register the transfer of the Definitive Certificates; or
<PAGE>

      (ii)  to exchange such Definitive Certificates for an equal number of
            Definitive Certificates of other authorized denominations,

the Transfer Agent shall register the transfer or make the exchange as requested
if the requirements under this Agreement as set forth in this Section 3.5 for
such transactions are met; provided, however, that the Definitive Certificates
presented or surrendered by a holder for registration of transfer or exchange:

      (x)   shall be duly endorsed or accompanied by a written instruction of
            transfer or exchange in form satisfactory to the Company and the
            Transfer Agent, duly executed by such holder or by his attorney,
            duly authorized in writing; and

      (y)   in the case of Shares the offer and sale of which have not been
            registered under the Securities Act and are presented for transfer
            or exchange prior to (X) the date which is two years (or such
            shorter period as may be prescribed by Rule 144(k) (or any successor
            provision thereto)) after the later of the date of original issuance
            of the Shares and the last date on which the Company or the LLC or
            any or their affiliates was the owner of such Shares, or any
            predecessor thereto, and (Y) such later date, if any, as may be
            required by any subsequent change in applicable law (the "Resale
            Restriction Termination Date"), such Shares shall be accompanied by
            the following additional information and documents, as applicable:

            (A)   if such Shares are being delivered to the Transfer Agent by a
                  holder for registration in the name of such holder, without
                  transfer, a certification from such holder to that effect (in
                  substantially the form of Exhibit C hereto); or

            (B)   if such Shares are being transferred to a qualified
                  institutional buyer (as defined in Rule 144A under the
                  Securities Act) (a "QIB") in accordance with Rule 144A under

            (C)   if such Shares are being transferred to an institutional
                  "accredited investor" within the meaning of subparagraphs
                  (a)(1), (a)(2), (a)(3) or (a)(7) of Rule 501 under the
                  Securities Act (an "Institutional Accredited Investor"),
                  delivery by the transferor of a certification to that effect
                  (in substantially the form of Exhibit C hereto), and delivery
                  by the proposed transferee of a Transferee Certificate for
                  Institutional Accredited Investors (in substantially the form
                  of Exhibit D hereto); or

            (D)   if such Shares are being transferred in reliance on Regulation
                  S under the Securities Act, delivery by the transferor of a
                  certification to that effect (in substantially the form of
                  Exhibit C hereto), and a Certificate for Regulation S
                  Transfers in the form of Exhibit E hereto; or

            (E)   if such Shares are being transferred in reliance on Rule 144
                  under the Securities Act, delivery by the transferor of (i) a
                  certification from the transferor to that effect (in
                  substantially the form of Exhibit C hereto), and (ii) an
                  opinion of counsel reasonably satisfactory to the Company or
                  the LLC, as the case may be, to the effect that such transfer
                  is in compliance with the Securities Act; or

            (F)   if such Shares are being transferred in reliance on another
                  exemption from the registration requirements of the Securities
                  Act, a certification from the transferor to that effect (in
                  substantially the form of Exhibit C hereto) and an opinion of
                  counsel reasonably satisfactory to the Company or the LLC, as
                  the case may be, to the effect that such transfer is in
                  compliance with the Securities Act; provided that the Company
                  or the LLC, as the case may be, may, based upon the views of
                  its own counsel, instruct the Transfer Agent not to register
                  such transfer in any case where the proposed transferee is not
                  a QIB, non-U.S. Person (as defined in Regulation S) or
                  Institutional Accredited Investor.

            (b) Restrictions on Transfer of a Definitive Certificate for a
Beneficial Interest in a Global Certificate. A Definitive Certificate may not be
transferred by a holder for a
<PAGE>

                                      -23-


beneficial interest in a Global Certificate except upon satisfaction of the
requirements set forth below. Upon receipt by the Transfer Agent of a Definitive
Certificate, duly endorsed or accompanied by appropriate instruments of
transfer, in form satisfactory to the Transfer Agent, together with:

            (A)   certification from such holder (in substantially the form of
                  Exhibit C hereto) that such Definitive Certificate is being
                  transferred to a QIB in accordance with Rule 144A under the
                  Securities Act; and

                  Certificate to reflect an increase in the aggregate amount of
                  the Shares represented by the Global Certificate,

then the Transfer Agent shall cancel such Definitive Certificate and cause, or
direct the Depositary to cause, in accordance with the standing instructions and
procedures existing between the Depositary and the Transfer Agent, the number of
Shares represented by the Global Certificate to be increased accordingly. If no
Global Certificate is then outstanding, the Company shall issue and the Transfer
Agent shall upon written instructions from the Company authenticate a new Global
Certificate in the appropriate amount.

            (c) Transfer or Exchange of Global Certificates. The transfer or
exchange of Global Certificates or beneficial interests therein shall be
effected through the Depositary, in accordance with this Section 3.5, the
Private Placement Legend, this Agreement (including the restrictions on transfer

            the Depositary from the Depositary or its nominee on behalf of any
            person having a beneficial interest in a Global Certificate,

            in the case of

            any such transfer or exchange prior to the Resale Restriction
            Termination Date, the following additional information and
            documents:

            (A)   if such beneficial interest is being transferred to the person
                  designated by the Depositary as being the beneficial owner, a
                  certification from such person to that effect (in
                  substantially the form of Exhibit C hereto); or

            (B)   if such beneficial interest is being transferred to a QIB in
                  accordance with Rule 144A under the Securities Act, a
                  certification from the transferor to that effect (in

                  of Exhibit C hereto), and delivery by the proposed transferee
                  of a Transferee Certificate for Institutional Accredited
                  Investors (in substantially the form of Exhibit D hereto); or

            (D)   if such beneficial interest is being transferred in reliance
                  on Regulation S under the Securities Act, delivery by the
                  transferor of (i) a certification to that effect (in
                  substantially in the form of Exhibit C hereto), and (ii) a
                  Certificate for Regulation S Transfers in the form of Exhibit
                  E hereto; or

            (E)   if such beneficial interest is being transferred in reliance

                  is in compliance with the Securities Act; or

            (F)   if such beneficial interest is being transferred in reliance
                  on another exemption from the registration requirements of the

                  and an opinion of counsel reasonably satisfactory to the
                  Company or the LLC, as the case may be, to the effect that
                  such transfer is in compliance with the Securities Act;
                  provided that the Company or the LLC, as the case may be, may
                  instruct the Transfer Agent not to register such transfer in
                  any case where the proposed transferee is not a QIB, non-U.S.
                  Person or Institutional Accredited Investor;

            then the Transfer Agent will cause, in accordance with the standing
            instructions and procedures existing between the Depositary and the
            Transfer Agent, the aggregate amount of the Global Certificate to be
            reduced and, following such reduction, the Company will execute and,
            upon receipt of an authentication order in the form of an officers'
            certificate (a certificate signed by two officers of such company,
            one of whom must be the principal executive officer, principal
            financial officer or principal accounting officer) (an "Officers'
            Certificate"), the Transfer Agent will authenticate and deliver to
            the transferee a Definitive Certificate.

      (ii)  Definitive Certificates issued in exchange for a beneficial interest
            in a Global Certificate pursuant to this Section 3.5(d) shall be
            registered in such names and in such authorized denominations as the
            Depositary, pursuant to instructions from its direct or indirect
            participants or otherwise, shall instruct the Transfer Agent in
            writing. The Transfer Agent shall deliver such Definitive
            Certificates to the persons in whose names such Shares are so
            registered and adjust the Global Certificate pursuant to paragraph
            (h) of this Section 3.5.

            (e) Restrictions on Transfer or Exchange of Global Certificates.
Notwithstanding any other provisions of this Agreement (other than the
provisions set forth in subsection (f) of this Section 3.5), a Global
Certificate may not be transferred or exchanged as a whole except by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to
the Depositary or another nominee of the Depositary or by the Depositary or any
such nominee to a successor Depositary or a nominee of such successor
Depositary.

            (f) Authentication of Definitive Certificates in Absence of
Depositary. If at any time:
<PAGE>

                                      -26-


      (i)   the Depositary for the Global Certificates notifies the Company that
            the Depositary is unwilling or unable to continue as Depositary for
            the Global Certificate and a successor Depositary for the Global
            Certificate is not appointed by the Company within 90 days after
            delivery of such notice; or

      (ii)  the Company and, if prior to the occurrence of a Liquidation Event,
            the LLC, notify the Transfer Agent in writing that it elects to
            cause the issuance of Definitive Certificates for all Global
            Certificates under this Agreement,

then the Company and, if applicable, the LLC, will execute, and the Transfer
Agent will, upon receipt of an Officers' Certificate requesting the
authentication and delivery of Definitive Certificates, authenticate and deliver
Definitive Certificates, in an aggregate number equal to the aggregate number of
Shares represented by the Global Certificate, in exchange for such Global
Certificate.

            (g) Private Placement Legend. Upon the registration of transfer,
exchange or replacement of Share certificates not bearing the legend set forth
in the first paragraph of Exhibit A attached hereto (the "Private Placement
Legend"), the Transfer Agent shall deliver Share certificates that do not bear
the Private Placement Legend. Upon the registration of transfer, exchange or
replacement of Share certificates bearing the Private Placement Legend, the
Transfer Agent shall deliver Share certificates that bear the Private Placement
Legend unless, and the Transfer Agent is hereby authorized to deliver Share
certificates without the Private Placement Legend if, (i) the requested transfer
is not prior to the date which is two years (or such shorter period as may be
prescribed by Rule 144(k) (or any successor provision thereto) under the
Securities Act or any successor provision thereunder) after the later of the
original Issue Date of the Shares or the last day on which the Company or the
LLC, as the case may be, or any of its Affiliates was the owner of the Shares or
any predecessor security, (ii) there is delivered to the Transfer Agent an
opinion of counsel reasonably satisfactory to the Company and the Transfer Agent
to the effect that neither such legend nor the related restrictions on transfer
are required in order to maintain compliance with the provisions of the
Securities Act or (iii) the Shares to be transferred or exchanged represented by
such Share Certificates are being transferred or exchanged pursuant to an
effective registration statement under the Securities Act.

            (h) Cancellation or Adjustment of a Global Certificate. At such time
as all beneficial interests in a Global Certificate have either been exchanged
for Definitive Certificates, redeemed, repurchased or cancelled, such Global
Certificate shall be returned to the Company or the LLC, as the case may be, or,
upon written order to the Transfer Agent in the form of an Officers' Certificate
from the Company or the LLC, as the case may be, retained and cancelled by the
Transfer Agent. At any time prior to such cancellation, if any beneficial
interest in a Global Certificate is exchanged for Definitive Certificates,
redeemed, repurchased or cancelled, the number of Shares represented by such
Global Certificate shall be reduced and an endorsement shall be made on such
Global Certificate by the Transfer Agent to reflect such reduction.

            (i) Obligations with Respect to Transfers or Exchanges of Definitive
Certificates.

      (i)   To permit registrations of transfers or exchanges, the Company or
            the LLC, as the case may be, shall execute, at the Transfer Agent's
            request, and the Transfer Agent shall authenticate Definitive
            Certificates and Global Certificates.

      (ii)  All Definitive Certificates and Global Certificates issued upon any
            registration, transfer or exchange of Definitive Certificates or
            Global Certificates shall be the valid obligations of the Company or
            the LLC, as the case may be, entitled to the same benefits under
            this Agreement as the Definitive Certificates or Global Certificates
            surrendered upon the registration of transfer or exchange.

      (iii) Prior to due presentment for registration of transfer of any Shares,
            the Transfer Agent and the Company or the LLC, as the case may be,
            may deem and treat the person in whose name any Shares are
            registered as the absolute owner of such Shares, and neither the
            Transfer Agent nor the Company or the LLC, as the case may be, shall
            be affected by notice to the contrary.

            (j) Compliance. Other than following the applicable terms and
requirements of this Agreement, the Transfer Agent shall have no additional duty
to monitor compliance with federal, state or other securities laws.

            3.6. Lost, Stolen, Destroyed, Defaced or Mutilated Share
Certificates. Upon receipt by the Company and the Transfer Agent (or any agent
of the Company or the Transfer Agent, if requested by the Company) of evidence
satisfactory to them of the loss, theft, destruction, defacement, or mutilation
of any Share certificate and of an indemnity bond satisfactory to them and, in
the case of mutilation or defacement, upon surrender thereof to the Transfer
Agent for cancellation, then, in the absence of notice to the Company or the
Transfer Agent that such Share certificate has been acquired by a bona fide
purchaser or holder in due course, the Company shall execute, and an authorized
signatory of the Transfer Agent shall manually authenticate and deliver, in
exchange for or in lieu of the lost, stolen, destroyed, defaced or mutilated
Share certificate, a new Share certificate representing a like number of Shares,
bearing a number or other distinguishing symbol not contemporaneously
outstanding. Upon the issuance of any new Share certificate under this Section
in a name other than the prior registered holder of the lost, stolen, destroyed,
defaced or mutilated Share certificate, the Company or the LLC, as the case may
be, may require the payment from the holder of such Share certificate of a sum
sufficient to cover any tax, stamp tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Transfer Agent) in connection therewith. Every substitute Share
certificate executed and delivered pursuant to this Section in lieu of any lost,
stolen or destroyed Share certificate shall constitute an additional contractual
obligation of the Company or the LLC, as the case may be, whether or not the
lost, stolen or destroyed Share certificate shall be at any time enforceable by
anyone, and shall be entitled to the benefits of (but shall be subject to all
the limitations of rights set forth in) this Agreement equally and
proportionately with any and all other Share certificates duly executed and
delivered hereunder. The provisions of this Section 3.6 are exclusive with
respect to the replacement of lost, stolen, destroyed, defaced or mutilated
Share certificates and shall preclude (to the extent lawful) any and all other
rights or remedies notwithstanding any law or statute existing or hereafter
enacted to the contrary with respect to the replacement of lost, stolen,
destroyed, defaced or mutilated Share certificates.

            3.7. Separation of Shares and Notes. The Notes and the LLC Shares
will not be separately transferable until the Separability Date. "Separability
Date" shall mean the earliest to occur of: (i) six months after the offering,
(ii) the date on which a registration statement under the Securities Act,
<PAGE>

                                      -29-


with respect to a registered exchange offer for the Notes or covering the sale
by holders of the Notes is declared effective under the Securities Act, (iii)
the occurrence of an Event of Default (as defined in the Indenture), (iv)
immediately prior to the occurrence of a Change of Control (as defined in the
Indenture) or (v) such earlier date as may be determined by Merrill Lynch & Co.
in its sole discretion and specified to the Company, the LLC, the Trustee, the
Transfer Agent and the Unit Agent in writing. Notwithstanding the foregoing, in
the event a Change of Control (as defined in the Indenture) is proposed and the
Company commences a Change of Control Offer (as defined in the Indenture) prior
to the Separability Date, as determined by the preceding sentence, the
Separability Date shall be such earlier date of commencement. The separation of
the Shares and the Notes is herein referred to as a "Separation."

      4. Registration Procedures.

            In connection with the obligations of the Company with respect to
any Registration Statement pursuant to Sections 2.1 and 2.2 hereof, the Company
shall:

            (a) A reasonable period of time prior to the initial filing of a
      Registration Statement or Prospectus and a reasonable period of time prior
      to the filing of any amendment or supplement thereto (including any
      document that would be incorporated or deemed to be incorporated therein
      by reference), furnish to the Holders of the Registrable Securities
      included in such Registration Statement, and the managing underwriters, if
      any, copies of all such documents proposed to be filed, which documents
      (other than those incorporated or deemed to be incorporated by reference)
      will be subject to the review of such Holders, and such underwriters, if
      any, and use reasonable commercial efforts to cause the officers and
      directors of the Company, counsel to the Company and independent certified
      public accountants to the Company to respond to such reasonable inquiries
      as shall be necessary, in the opinion of respective counsel to such
      Holders and such underwriters, to conduct a reasonable investigation
      within the meaning of the Securities Act. The Company shall not file any
      such Registration Statement or related Prospectus or any amendments or
      supplements thereto to which the Holders of a majority of the Registrable
      Securities included in such Registration Statement shall reasonably object
      on a timely basis;
<PAGE>

                                      -30-


            (b) Prepare and file with the SEC such amendments, including
      post-effective amendments, to each Registration Statement as may be
      necessary to keep such Registration Statement continuously effective for
      the applicable time period required hereunder (except for Black Out
      Periods); cause the related Prospectus to be supplemented by any required
      Prospectus supplement, and as so supplemented to be filed pursuant to Rule
      424 under the Securities Act; and comply with the provisions of the
      Securities Act and the Exchange Act with respect to the disposition of all
      securities covered by such Registration Statement during such period in
      accordance with the intended methods of disposition by the sellers thereof
      set forth in such Registration Statement as so amended or in such
      Prospectus as so supplemented;

            (c) Notify the holders of Registrable Securities to be sold and the
      managing underwriters, if any, promptly, and (if requested by any such
      person), confirm such notice in writing, (i)(A) when a Prospectus or any
      Prospectus supplement or post-effective amendment is proposed to be filed,
      and (B) with respect to a Registration Statement or any post-effective
      amendment, when the same has become effective, (ii) of any request by the
      SEC or any other Federal or state governmental authority for amendments or
      supplements to a Registration Statement or related Prospectus or for
      additional information, (iii) of the issuance by the SEC, any state
      securities commission, any other governmental agency or any court or any
      stop order, order or injunction suspending or enjoining the use of a
      Prospectus or the effectiveness of a Registration Statement or the
      initiation of any proceedings for that purpose, (iv) of the receipt by the
      Company of any notification with respect to the suspension of the
      qualification or exemption from qualification of any of the Registrable
      Securities for sale in any jurisdiction, or the initiation or threatening
      of any proceeding for such purpose, and (v) of the happening of any event
      or information becoming known that makes any statement made in a
      Registration Statement or related Prospectus untrue in any material
      respect or that requires the making of any changes in such Registration
      Statement or Prospectus so that, in the case of a Registration Statement,
      it will not contain any untrue statement of a material
<PAGE>

                                      -31-


      fact or omit to state any material fact required to be stated therein or
      necessary to make the statements therein not misleading, and that in the
      case of a Prospectus, it will not contain any untrue statement of a
      material fact or omit to state any material fact required to be stated
      therein or necessary to make the statements therein, in light of the
      circumstances under which they were made, not misleading;

            (d) Use its reasonable best efforts to avoid the issuance of or, if
      issued, obtain the withdrawal of any order enjoining or suspending the use
      of a Prospectus or the effectiveness of a Registration Statement or the
      lifting of any suspension of the qualification (or exemption from
      qualification) of any of the Registrable Securities for sale in any
      jurisdiction described in Section 4(h), at the earliest practicable
      moment;

            (e) If requested by the managing underwriters, if any, (i) promptly
      incorporate in a Prospectus supplement or post-effective amendment such
      information as the managing underwriters, if any, reasonably believe
      should be included therein, and (ii) make all required filings of such
      Prospectus supplement or such post-effective amendment under the
      Securities Act as soon as practicable after the Company has received
      notification of the matters to be incorporated in such Prospectus
      supplement or post-effective amendment; provided, however, that the
      Company shall not be required to take any action pursuant to this Section
      4(e) that would, in the opinion of counsel for the Company, violate
      applicable law;

            (f) Upon written request to the Company, furnish to each Holder of
      Registrable Securities to be sold pursuant to a Registration Statement and
      each managing underwriter, if any, without charge, at least one conformed
      copy of such Registration Statement and each amendment thereto, including
      financial statements and schedules, all documents incorporated or deemed
      to be incorporated therein by reference, and all exhibits to the extent
      requested (including those previously furnished or incorporated by
      reference) as soon as practicable after the filing of such documents with
      the SEC;

            (g) Deliver to each Holder of Registrable Securities to be sold
      pursuant to a Registration Statement, and the underwriters, if any,
      without charge, as many copies of the Prospectus (including each form of
      prospectus) and each amendment or supplement thereto as such persons
      reasonably request; and the Company hereby consents to the use of such
      Prospectus and each amendment or supplement thereto by each of the selling
      holders of Registrable Securities and the underwriters, if any, in
      connection with
<PAGE>

                                      -32-


      the offering and sale of the Registrable Securities covered by such
      Prospectus and any amendment or supplement thereto;

            (h) Prior to any public offering of Registrable Securities, use its
      reasonable best efforts to register or qualify or cooperate with the
      Holders of Registrable Securities to be sold, the underwriters, if any,
      and their respective counsel in connection with the registration or
      qualification (or exemption from such registration or qualification) of
      such Registrable Securities for offer and sale under the securities or
      Blue Sky laws of such jurisdictions as any such Holder or underwriter
      reasonably requests in writing; keep each such registration or
      qualification (or exemption therefrom) effective during the period such
      Registration Statement is required to be kept effective hereunder and do
      any and all other acts or things necessary or advisable to enable the
      disposition in such jurisdictions of the Registrable Securities covered by
      the applicable Registration Statement; provided, however, that the Company
      shall not be required to (i) qualify generally to do business in any
      jurisdiction where it is not then so qualified or (ii) take any action
      which would subject it to general service of process or to taxation in any
      jurisdiction where they are not so subject;

            (i) In connection with any sale or transfer of Registrable
      Securities that will result in such securities no longer being Registrable
      Securities, cooperate with the Holders thereof and the managing
      underwriters, if any, to facilitate the timely preparation and delivery of
      certificates representing Registrable Securities to be sold, which
      certificates shall not bear any restrictive legends and shall be in a form
      eligible for deposit with The Depository Trust Company and to enable such
      Registrable Securities to be in such denominations and registered in such
      names as the managing underwriters, if any, or such Holders may request at
      least two Business Days prior to any sale of Registrable Securities;

            (j) Upon the occurrence of any event contemplated by Section
      4(c)(v), except during Black Out Periods as promptly as practicable,
      prepare a supplement or amendment, including, if appropriate, a
      post-effective amendment, to each Registration Statement or a supplement
      to the related Prospectus or any document incorporated or deemed to be
      incorporated therein by reference, and file
<PAGE>

                                      -33-


      any other required document so that, as thereafter delivered, such
      Prospectus will not contain an untrue statement of a material fact or omit
      to state a material fact required to be stated therein or necessary to
      make the statements therein, in the light of the circumstances under which
      they were made, not misleading;

            (k) Enter into such agreements (including an underwriting agreement
      in form, scope and substance as is customary in underwritten offerings)
      and take all such other reasonable actions in connection therewith
      (including those reasonably requested by the managing underwriters, if
      any) in order to expedite or facilitate the disposition of such
      Registrable Securities, and, whether or not an underwriting agreement is
      entered into and whether or not the registration is an underwritten
      registration, (i) make such representations and warranties to the
      underwriters and selling Holders, if any, with respect to the business of
      the Company and its subsidiaries (including with respect to businesses or
      assets acquired or to be acquired by any of them), and the Registration
      Statement, Prospectus and documents, if any, incorporated or deemed to be
      incorporated by reference therein, in each case, in form, substance and
      scope as are customarily made by issuers to underwriters in underwritten
      offerings, and confirm the same if and when requested; (ii) in the case of
      an underwritten offering, obtain opinions of counsel to the Company and
      updates thereof (which counsel and opinions (in form, scope and substance)
      shall be reasonably satisfactory to the managing underwriters, addressed
      to each of the underwriters, and selling Holders), covering the matters
      customarily covered in opinions requested in underwritten offerings and
      such other matters as may be reasonably requested by such underwriters or
      selling Holders; (iii) use their reasonable best efforts to obtain
      customary "cold comfort" letters and updates thereof from the independent
      certified public accountants of the Company (and, if necessary, any other
      independent certified public accountants of any subsidiary of the Company
      or of any business acquired by the Company for which financial statements
      and financial data is, or is required to be, included in the Registration
      Statement), addressed (where reasonably possible) to each of the
      underwriters and selling Holders, if any, such letters to be in customary
      form and covering matters of the type customarily covered in "cold
      comfort" letters in connection with underwritten offerings; (iv) if an
      underwriting agreement is entered into, the same shall contain
      indemnification provisions
<PAGE>

                                      -34-


      and procedures no less favorable to the underwriters, if any, than those
      set forth in Section 5 hereof (or such other provisions and procedures
      acceptable to the managing underwriters, if any); and (v) deliver such
      documents and certificates as may be reasonably requested by the managing
      underwriters, if any, to evidence the continued validity of the
      representations and warranties made pursuant to clause (i) above and to
      evidence compliance with any customary conditions contained in the
      underwriting agreement or other agreement entered into by the Company;

            (l) Make available for inspection by a representative of any
      underwriter participating in any such disposition of Registrable
      Securities, and any attorney, consultant or accountant retained by such
      selling Holders or underwriter, at the offices where normally kept, during
      reasonable business hours, all pertinent financial and other records,
      corporate documents and properties of the Company and its subsidiaries
      (including with respect to businesses and assets acquired or to be
      acquired to the extent that such information is available to the Company),
      and cause the officers, directors, agents and employees of the Company and
      its subsidiaries (including with respect to businesses and assets acquired
      or to be acquired to the extent that such information is available to the
      Company) to supply all information in each case reasonably requested by
      any such representative, underwriter, attorney, consultant or accountant
      in connection with such Registration Statement; provided, however, that
      such persons shall first agree in writing with the Company that any
      information that is reasonably and in good faith designated by the Company
      in writing as confidential at the time of delivery of such information
      shall be kept confidential by such Persons, unless (i) disclosure of such
      information is required by court or administrative order or is necessary
      to respond to inquiries of regulatory authorities, (ii) disclosure of such
      information is required by law (including any disclosure requirements
      pursuant to Federal securities laws in connection with the filing of the
      Registration Statement or the use of any Prospectus), (iii) such
      information becomes generally available to the public other than as a
      result of a disclosure or failure to safeguard such information by such
      Person or (iv) such information becomes available to such Person from a
      source other than the Company and its subsidiaries and such source is not
      bound by a confidentiality agreement;
<PAGE>

                                      -35-


            (m) Comply with all applicable rules and regulations of the SEC and
      make generally available to their securityholders earnings statements
      satisfying the provisions of Section 11(a) of the Securities Act and Rule
      158 under the Securities Act, no later than 45 days after the end of any
      12-month period (or 90 days after the end of any 12-month period if such
      period is a fiscal year) (i) commencing at the end of any fiscal quarter
      in which Registrable Securities are sold to underwriters in a firm
      commitment or reasonable efforts underwritten offering and (ii) if not
      sold to underwriters in such an offering, commencing on the first day of
      the first fiscal quarter after the effective date of a Registration
      Statement, which statement shall cover said period, consistent with the
      requirements of Rule 158 under the Securities Act; and

            (n) Cooperate with each seller of Registrable Securities covered by
      any Registration Statement and each underwriter, if any, participating in
      the disposition of such Registrable Securities and their respective
      counsel in connection with any filings required to be made with the
      National Association of Securities Dealers, Inc.

            The Company may require a Holder of Registrable Securities to be
included in a Registration Statement to furnish to the Company such information
regarding (i) the intended method of distribution of such Registrable Securities
(ii) such Holder and (iii) the Registrable Securities held by such Holder as is
required by law to be disclosed in such Registration Statement and the Company
may exclude from such Registration Statement the Registrable Securities of any
Holder who unreasonably fails to furnish such information within a reasonable
time after receiving such request. The Company shall not be required to provide
indemnification to any Underwriter or any other person relating to information
referred to in clauses (i) and (ii) provided to the Company in writing
specifically for inclusion in such Registration Statement.

            If any such Registration Statement refers to any Holder by name or
otherwise as the Holder of any securities of the Company, then such Holder shall
have the right to require (i) the insertion therein of language, in form and
substance reasonably satisfactory to such Holder, to the effect that the holding
by such Holder of such securities is not to be construed as a recommendation by
such Holder of the investment quality of the Company's securities covered
thereby and that such holding does not imply that such Holder will assist in
meeting any future financial requirements of the Company, or
<PAGE>

                                      -36-


(ii) in the event that such reference to such Holder by name or otherwise is not
required by the Securities Act, the deletion of the reference to such Holder in
any amendment or supplement to the Registration Statement filed or prepared
subsequent to the time that such reference ceases to be required.

            Each Holder of Registrable Securities agrees by acquisition of such
Registrable Securities that, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 4(c)(ii), 4(c)(iii),
4(c)(iv) or 4(c)(v) hereof, such Holder will forthwith discontinue disposition
of such Registrable Securities covered by such Registration Statement or
Prospectus until such Holder's receipt of the copies of the supplemented or
amended Prospectus contemplated by Section 4(j) hereof, or until it is advised
in writing (the "Advice") by the Company that the use of the applicable
Prospectus may be resumed, and, in either case, has received copies of any
additional or supplemental filings that are incorporated or deemed to be
incorporated by reference in such Prospectus. If the Company shall give any such
notice, the Effectiveness Period shall be extended by the number of days during
such period from and including the date of the giving of such notice to and
including the date when each Holder of Registrable Securities covered by such
Registration Statement shall have received (x) the copies of the supplemented or
amended Prospectus contemplated by Section 4(j) hereof or (y) the Advice, and,
in either case, has received copies of any additional or supplemental filings
that are incorporated or deemed to be incorporated by reference in such
Prospectus.

      5. Indemnification and Contribution.

            (a) Each Issuer agrees, jointly and severally, to indemnify and hold
harmless each Initial Purchaser, each Holder, each underwriter who participates
in an offering of Registrable Securities, their respective Affiliates, each
Person, if any, who controls any of such parties within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act and each of their
respective directors, officers, employees and agents, as follows:

            (i) against any and all loss, liability, claim, damage and expense
      whatsoever, joint or several, as incurred, arising out of any untrue
      statement or alleged untrue statement of a material fact contained in any
      Registration Statement (or any amendment thereto), covering Registrable
      Securities, including all documents incorporated therein by reference, or
      the omission or alleged omission there-
<PAGE>

                                      -37-


      from of a material fact required to be stated therein or necessary to make
      the statements therein, in the light of the circumstances under which they
      were made, not misleading or arising out of any untrue statement or
      alleged untrue statement of a material fact contained in any Prospectus
      (or any amendment or supplement thereto) or the omission or alleged
      omission therefrom of a material fact necessary in order to make the
      statements therein, in the light of the circumstances under which they
      were made, not misleading;

            (ii) against any and all loss, liability, claim, damage and expense
      whatsoever, joint or several, as incurred, to the extent of the aggregate
      amount paid in settlement of any litigation, or any investigation or
      proceeding by any court or governmental agency or body, commenced or
      threatened, or of any claim whatsoever based upon any such untrue
      statement or omission, or any such alleged untrue statement or omission;
      provided that (subject to Section 5(d) below) any such settlement is
      effected with the written consent of the Issuers; and

            (iii) against any and all expenses whatsoever, as incurred
      (including reasonable fees and disbursements of one counsel chosen by
      Merrill Lynch), reasonably incurred in investigating, preparing or
      defending against any litigation, or any investigation or proceeding by
      any court or governmental agency or body, commenced or threatened, or any
      claim whatsoever based upon any such untrue statement or omission, or any
      such alleged untrue statement or omission, to the extent that any such
      expense is not paid under subparagraph (i) or (ii) of this Section 5(a);

provided that this indemnity does not apply to any loss, liability, claim,
damage or expense to the extent arising out of an untrue statement or omission
or alleged untrue statement or omission (i) made in reliance upon and in
conformity with written information furnished to any Issuer by an Initial
Purchaser, such Holder or any underwriter in writing expressly for use in the
Registration Statement (or any amendment thereto) or any Prospectus (or any
amendment or supplement thereto) or (ii) contained in any preliminary prospectus
if such Initial Purchaser, such Holder or such underwriter failed to send or
deliver a copy of the Prospectus (in the form it was first provided to such
parties for confirmation of sales) to the Person asserting such losses, claims,
damages or liabilities on or prior to the delivery of written confirmation of
any sale of securities covered thereby to such Person in any case where 
<PAGE>

                                      -38-


such delivery is required by the Securities Act and such Prospectus would have
corrected such untrue statement or omission. Any amounts advanced by any Issuer
to an indemnified party pursuant to this Section 5 as a result of such losses
shall be returned to such Issuer if it shall be finally determined by such a
court in a judgment not subject to appeal or final review that such indemnified
party was not entitled to indemnification by any Issuer.

            (b) By accepting the benefits of this Agreement, each Holder agrees,
severally and not jointly, to indemnify and hold harmless the Issuers, each
Initial Purchaser, each underwriter who participates in an offering of
Registrable Securities and the other selling Holders and each of their
respective directors, officers (including each officer of the Issuers who signed
the Registration Statement), employees and agents and each Person, if any, who
controls the Issuers, an Initial Purchaser through Merrill Lynch expressly for
use in the Offering Memorandum, any underwriter or any other selling Holder
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act, from and against any and all loss, liability, claim, damage and
expense whatsoever described in the indemnity contained in Section 5(a) hereof,
as incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto) in
reliance upon and in conformity with written information furnished to the
Issuers by such selling Holder expressly for use in the Registration Statement
(or any amendment thereto), or any such Prospectus (or any amendment or
supplement thereto).

            (c) Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, but failure to so notify an indemnifying
party shall not relieve such indemnifying party from any liability hereunder to
the extent it is not materially prejudiced as a result thereof and in any event
shall not relieve it from any liability which it may have otherwise than on
account of this indemnity agreement. In the case of parties indemnified pursuant
to Section 5(a) above, counsel to the indemnified parties shall be selected by
Merrill Lynch and, in the case of parties indemnified pursuant to Section 5(b)
above, counsel to the indemnified parties shall be selected by the Issuers.
Notwithstanding the foregoing sentence, in case any such action is brought
against any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to
<PAGE>

                                      -39-


participate therein and, to the extent it may wish, jointly with any other
indemnifying party similarly notified, unless such indemnified party shall have
one or more legal defenses available to it which are not available to the
indemnifying party, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party. After notice from the indemnifying party
to such indemnified party of its election as aforesaid to assume the defense
thereof and approval by such indemnified party of counsel appointed to defend
such action, the indemnifying party will not be liable to such indemnified party
under this Section 5 for any legal or other expenses other than reasonable costs
of investigation, subsequently incurred by such indemnified party in connection
with the defense thereof. An indemnifying party may participate at its own
expense in the defense of any such action; provided, however, that counsel to
the indemnifying party shall not (except with the consent of the indemnified
party) also be counsel to the indemnified party. In no event shall the
indemnifying parties be liable for fees and expenses of more than one counsel
(in addition to any local counsel) separate from their own counsel for all
indemnified parties in connection with any one action or separate but similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances. No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any Judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 5 (whether or not the indemnified parties are
actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

            (d) If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 5(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying
<PAGE>

                                      -41-


party shall not have reimbursed such indemnified party in accordance with such
request prior to the date of such settlement.

            (e) In order to provide for just and equitable contribution in
circumstances under which any of the indemnity provisions set forth in this
Section 5 is for any reason held to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Issuers, each Initial
Purchaser and the Holders shall contribute to the aggregate losses, liabilities,
claims, damages and expenses of the nature contemplated by such indemnity
agreement incurred by the Issuers, the Initial Purchasers and the Holders, as
incurred; provided that no Person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person that was not guilty of such fraudulent
misrepresentation. As between the Issuers, the Initial Purchasers and the
Holders, such parties shall contribute to such aggregate losses, liabilities,
claims, damages and expenses of the nature contemplated by such indemnity
agreement in such proportion as shall be appropriate to reflect the relative
fault of either of the Issuers, on the one hand, and the Initial Purchasers and
the Holders, on the other hand, with respect to the statements or omissions
which resulted in such loss, liability, claim, damage or expense, or action in
respect thereof, as well as any other relevant equitable considerations. The
relative fault of either of the Issuers, on the one hand, and of the Initial
Purchasers and the Holders, on the other hand, shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by either of the Issuers, on the one hand, or by
or on behalf of an Initial Purchaser or the Holders, on the other, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Issuers, the Initial
Purchasers and the Holders of the Registrable Securities agree that it would not
be just and equitable if contribution pursuant to this Section 5 were to be
determined by pro rata allocation or by any other method of allocation that does
not take into account the relevant equitable considerations. For purposes of
this Section 5, each Affiliate of each Initial Purchaser or a Holder, and each
director, officer, employee, agent and Person, if any, who controls an Initial
Purchaser or Holder or such Affiliate within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act shall have the same rights to
contribution as such Initial Purchaser or Holder, and each director of the any
Is-
<PAGE>

                                      -41-


suer, each officer of any Issuer who signed the Registration Statement, and
each Person, if any, who controls either Issuer within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act shall have the same
rights to contribution as the Issuers.

      6. Rule 144A and Future IPOs

            (a) The Company and the LLC shall use their respective best efforts
to file the reports required to be filed by it under the Securities Act and the
Exchange Act in a timely manner and, if at any time it is not required to file
such reports but in the past had been required to or did file such reports, it
will, upon the request of any holder or beneficial owner of Registrable
Securities, make available other information as required by, and so long as
necessary to permit, sales of Registrable Securities pursuant to Rule 144A.
Notwithstanding the foregoing, nothing in this Section 6 shall be deemed to
require the Company or the LLC to register any of its securities pursuant to the
Exchange Act.

            (b) The Company hereby agrees not to make an Initial Public Equity
Offering of any class of Common Stock without amending, if necessary, the terms
of the Company's Estatutos to provide that the existing Common Stock is
convertible into such class of Common Stock on a share-for-share basis and that
the rights, conditions and privileges attaching to such class of Common Stock
are not adverse to holders of the existing Common Stock.

      7. Underwritten Registrations

            No Person may participate in any underwritten registration hereunder
unless such person (i) agrees to sell such Registrable Securities on the basis
reasonably provided in any underwriting arrangements approved by the Persons
entitled hereunder to approve such arrangements and (ii) completes and executes
all questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents required under the terms of such underwriting arrangements.

      8. Miscellaneous

            (a) Remedies. In the event of a breach by the Company, the LLC, any
Shareholder or by a holder of Shares of any of its obligations under this
Agreement, each holder of Shares, the LLC, any Shareholder and the Company, in
addition to being entitled to exercise all rights granted by law, including re-
<PAGE>

                                      -42-


covery of damages, will be entitled to specific performance of its rights
under this Agreement. The Company, the LLC, any Shareholder and each holder of
Shares agree that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach of any of the provisions of this Agreement
and each hereby further agrees that, in the event of any action for specific
performance in respect of such breach, it shall waive the defense that a remedy
at law would be adequate.

            (b) No Inconsistent Agreements. Except for certain registration
rights granted to the Shareholders pursuant to the Registration Rights
Agreement, dated as of December 9, 1996, among the Company and the Shareholders,
the Company, the LLC and the Shareholders have not entered into and shall not
enter into any agreement that is inconsistent with the rights granted to the
holders of Shares and indemnified persons in this Agreement or otherwise
conflicts with the provisions hereof. Except for certain registration rights
granted to the Shareholders pursuant to the Registration Rights Agreement, dated
as of December 9, 1996, among the Company and the Shareholders, without the
written consent of the holders of a majority of the outstanding Shares
(including for this purpose the Percentage Interest of any holder of LLC
Shares), the Company, the LLC and the Shareholders have not granted and shall
not grant to any Person any rights which conflict with or are inconsistent with
the provisions of this Agreement.

            (c) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, otherwise than with the prior written consent of the holders
of not less than a majority of the then outstanding Shares and/or Registrable
Securities, as applicable (including for this purpose the Percentage Interest of
any holder of LLC Shares). Notwithstanding the foregoing, a waiver or consent to
depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of Holders whose securities are being sold pursuant to
a Registration Statement and that does not directly or indirectly affect the
rights of other Holders may be given by Holders of a majority of the Registrable
Securities being sold by such Holders pursuant to such Registration Statement;
provided, however, that the provisions of this sentence may not be amended,
modified or supplemented except in accordance with the provisions of the
immediately preceding sentence. Notwithstanding the foregoing, no amendment,
modification, supplement, waiver or consent with respect to Section 5 shall be
made or given otherwise than with the prior

written consent of each Holder or former Holder affected thereby.

            (e) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors and permitted assigns of each of
the parties hereto and shall inure to the benefit of each holder of Shares and
Registrable Securities. Neither the Company nor the LLC may assign any of its
rights hereunder without the prior written consent of each holder of Shares and
Registrable Securities, provided that a merger or consolidation of the Company
with another Person pursuant to which the issuer or issuers of any securities
issued to holders of Shares or Registrable Securities in connection with such
merger or consolidation becomes obligated under this Agreement and each of the
Shareholders confirm their agreements with respect to the securities of such
issuer or issuers shall not be considered an assignment. Notwithstanding the
foregoing, no successor or assignee of the Company shall have any of the rights
granted under this Agreement until such Person shall acknowledge its rights and
obligations hereunder by a signed written statement of such Person's acceptance
of such rights and obligations. If any transferee of any holder shall acquire
Shares or Registrable Securities, in any manner, whether by operation of law or
otherwise, such Shares or Registrable Securities shall be held subject to all of
the terms of this Agreement, and by taking and holding such Shares or
Registrable Securities such person shall be conclusively deemed to have agreed
to be bound by and to perform all of the terms and provisions of this Agreement
and such person shall be entitled to receive the benefits hereof.

            (f) Counterparts. This Agreement may be executed by manual or
facsimile signature in any number of counterparts and by the parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and, all of which taken together shall constitute one and the same
Agreement.

            (g) Governing Law; Submission to Jurisdiction. THIS AGREEMENT SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK.
THE COMPANY, THE LLC, THE SHAREHOLDERS AND THE INITIAL PURCHASERS HEREBY

            (h) Severability. The remedies provided herein are cumulative and

be invalid, illegal, void or unenforceable, the remainder of the terms,
provisions, covenants and restrictions set forth herein shall remain in full
force and effect and shall in no way be affected, impaired or invalidated, and
the parties hereto shall use their reasonable efforts to find and employ an
alternative means to achieve the same or substantially the same result as that
contemplated by such term, provision, covenant or restriction. It is hereby
stipulated and declared to be the intention of the parties that they would have
executed the remaining terms, provisions, covenants and restrictions without
including any of such that may be hereafter declared invalid, illegal, void or
unenforceable.

            (i) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof. All
references made in this Agreement to "Section" and "paragraph" refer to such
Section or paragraph of this Agreement, unless expressly stated otherwise.

            (j) Agent for Service; Submission to Jurisdiction; Waiver of
Immunities. By the execution and delivery of this Agreement, each of the
Company, PNNV, IVP, TVA and MT (i) hereby designates and appoints CT Corporation

and agrees to furnish to each other party hereto, promptly following the
execution hereof, satisfactory evidence that CT Corporation System has accepted

<PAGE>

                                      -46-


Each of the Issuers and the Shareholders further agrees to take any and all
action, including the execution and filing of any and all such documents and
instruments, as may be necessary to continue such designation and appointment of
CT Corporation System in full force and effect so long as any of the Units, the
Notes, the Exchange Notes or the Private Exchange Notes shall be outstanding;
provided that each of the Issuers and Shareholders may and to the extent CT
Corporation System ceases to be able to be served on the basis contemplated
herein shall, by written notice to the Initial Purchasers, designate such
additional or alternative agent for service of process under this Section 8(j)
that (i) maintains an office located in the Borough of Manhattan, City of New
York, State of New York and (ii) is either (x) counsel for such Issuer or
Shareholder or (y) a corporate service company which acts as agent for service
of process for other persons in the ordinary course of its business. Such
written notice shall identify the name of such agent for service of process and
the address of the office of such agent for service of process in the Borough of
Manhattan, City of New York, State of New York.

            To the extent that any of the Issuers or Shareholders has or
hereafter may acquire any immunity from jurisdiction of any court of (i) any
jurisdiction in which they own or lease property or assets, (ii) the United
States or the State of New York or (iii) the Federative Republic of Brazil or
any political subdivision thereof or from any legal process (whether through
service of notice, attachment prior to judgment, attachment in aid of execution,
execution or otherwise) with respect to itself or its property and assets or
this Agreement or any of the Units, the Notes, Exchange Notes or Private
Exchange Notes (as those terms are defined in the Purchase Agreement) or actions
to enforce judgments in respect of any thereof, each of the Issuers and
Shareholders hereby irrevocably waives such immunity in respect of its
obligations under the above-referenced documents, to the extent permitted by
law.

            (iv) We understand that, on any proposed resale of Securities, we
will be required to furnish to the Transfer Agent and the Company, such
certification, legal opinions and other information as the Transfer Agent and
the Company may reasonably require to confirm that the proposed sale complies

      balance of funds held in the Escrow Account, provide for the payment of
      interest on the outstanding Secu-

      rities on each Interest Payment Date beginning on and including December
      6, 1997 and through and including the Interest Payment Date on June 6,
      2000; provided, further, however, that any such written instruction shall
      specify the particular investment to be made, shall state that such
      investment is authorized to be made hereby and in particular satisfies the
      requirements of the preceding proviso and Section 2(d)(v), shall contain
      the certification referred to in Section 2(d)(ii), if required, and shall
      be executed by an Officer of the Company. All U.S. Government Securities
      shall be assigned to and held in the possession of, or, in the case of
      U.S. Government Securities maintained in book entry form with the Federal
      Reserve Bank (i.e., TRADES), transferred to a book entry account in the
      name of, the Escrow Agent, for the benefit of the Trustee, with such
      guarantees as are customary, except that U.S. Government Securities
      maintained in book entry form with the Federal Reserve Bank shall be
      transferred to a book entry account in the name of the Escrow Agent at the
      Federal Reserve Bank that includes only U.S. Government Securities held by
      the Escrow Agent for its customers and segregated by separate recordation
      in the books and records of the Escrow Agent of the security interest in
      favor of the Trustee and confirmed in writing to the Trustee. The Company
      shall execute and deliver to the Trustee a UCC-1 Financing Statement
      covering all its rights in the Collateral and the proceeds thereof, and
      the Escrow Agent shall cause such Financing Statement to be filed with the
      Department of State of the State of New York as required by the Uniform
      Commercial Code of the State of New York. The Escrow Agent shall not be
      liable for losses on any investments made by it pursuant to and in
      compliance with such instructions. In the absence of qualifying
      instructions from the Company that meet the requirements of this Section
      2(d)(i), the Escrow Agent shall have no obligation to invest funds held in
      the Escrow Account.

            (ii) Security Interest in Investments. No investment of funds in the
      Escrow Account shall be made unless the Company has certified to the
      Escrow Agent and the 
<PAGE>
                                      -6-


      Trustee that, upon such investment, the Trustee will have a first priority
      perfected security interest in the applicable investment. If a certificate
      as to a class of investments has been provided to the Escrow Agent, a
      certificate need not be issued with respect to individual investments in
      securities in that class if the certificate applicable to the class
      remains accurate with respect to such individual investments, which
      continued accuracy the Escrow Agent may conclusively assume. On the Issue
      Date, and on each thereafter until the date upon which the balance of the
      Available Funds shall have been reduced to zero, each of the Trustee and
      the Escrow Agent shall receive an Opinion of Counsel to the Company, dated
      each such date as applicable, which opinion shall meet the requirements of
      Section 314(b) of the Trust Indenture Act of 1939, as amended (the "TIA")
      and shall comply with Section 12.02 of the Indenture. 

            (iii) Interest and Dividends. All interest earned and dividends paid
      on funds invested in U.S. Government Securities shall be deposited in the
      Escrow Account as additional Collateral for the exclusive benefit of the
      Beneficiaries and, if not required to be disbursed in accordance with the
      terms hereof, shall be reinvested in accordance with the terms hereof at
      the Company's written instruction. 

            (iv) Limitation on Escrow Agent's Responsibilities. The Escrow
      Agent's sole responsibilities under this Section 2 shall be (A) to retain
      possession of certificated U.S. Government Securities (except, however,
      that the Escrow Agent may surrender possession to the issuer of any such
      U.S. Government Security in New York for the purposes of effecting
      assignment, crediting interest, or reinvesting such security or reducing
      such security to cash) and to be the registered or designated owner of
      U.S. Government Securities which are not certificated, (B) to follow the
      Company's written instructions given in accordance with Section 2(d)(i),
      (C) to invest and reinvest funds pursuant to this Section 2(d) and (D) to
      use reasonable efforts to reduce to cash such U.S. Government Securities
<PAGE>
                                      -7-


      as may be required to fund any disbursement or payment in accordance with
      Section 3. In connection with clause (A) above, the Escrow Agent will
      maintain continuous possession in the State of New York of certificated
      U.S. Government Securities and cash included in the Collateral and will
      cause uncertificated U.S. Government Securities to be registered in the
      book-entry system of, and transferred to an account of the Escrow Agent or
      a sub-agent of the Escrow Agent at, the Federal Reserve Bank of New York.
      Except as provided in Section 6, the Escrow Agent shall have no other
      responsibilities with respect to perfecting or maintaining the perfection
      of the Trustee's security interest in the Collateral and shall not be
      required to file any instrument, document or notice in any public office
      at any time or times. In connection with clause (D) above and subject to
      the following sentence, the Escrow Agent shall not be required to reduce
      to cash any U.S. Government Securities to fund any disbursement or payment
      in accordance with Section 3 in the absence of written instructions signed
      by an Officer of the Company specifying the particular investment to
      liquidate. If no such written instructions are received, the Escrow Agent
      may liquidate those U.S. Government Securities having the lowest interest
      rate per annum or if none such exist, those having the nearest maturity.

            (v) Manner of Investment. Funds deposited in the Escrow Account
      shall initially be invested in accordance with the Initial Instructions
      (attached hereto as Schedule A), which is in a manner such that there will
      be sufficient funds available without any further investment by the
      Company to cover all interest due on the outstanding Securities, as such
      interest becomes due, for each Interest Payment Date occurring from the
      Issue Date and ending on (and including) June 6, 2000, provided that such
      investments shall have such maturities and/or interest payment dates such
      that funds will be available with respect to each such Interest Payment
      Date no later than the time the Escrow Agent is required to disburse such
      funds to the Trustee pursuant to Section 3(a). The Escrow Agent shall 
<PAGE>
                                      -8-


      have no responsibility for determining whether funds held in the Escrow
      Account shall have been invested in such a manner so as to comply with the
      requirements of this clause (v). 

            (e) Substitution of Escrow Agent. The Escrow Agent may resign by
giving no less than 20 Business Days prior written notice to the Company and the
Trustee. Such resignation shall take effect upon the later to occur of (i)
delivery of all funds and U.S. Government Securities maintained by the Escrow
Agent hereunder and copies of all books, records, plans and other documents in
the Escrow Agent's possession relating to such funds or U.S. Government
Securities or this Agreement to a successor escrow agent acceptable to the
Trustee (which approvals shall not be unreasonably withheld or delayed) and (ii)
the Company, the Trustee and such successor escrow agent entering into this
Agreement or any written successor agreement no less favorable to the interests
of the holders of the Securities and the Trustee than this Agreement; and the
Escrow Agent shall thereupon be discharged of all obligations under this
Agreement and shall have no further duties, obligations or responsibilities in
connection herewith, except as set forth in Section 4. If a successor escrow
agent has not been appointed or has not accepted such appointment within 20
Business Days after notice of resignation is given to the Company, the Escrow
Agent may apply to a court of competent jurisdiction for the appointment of a
successor escrow agent.

            (f) Escrow Account Statement. At least 30 days prior to each
Interest Payment Date, the Escrow Agent shall deliver to the Company and the
Trustee a statement setting forth with reasonable particularity the balance of
funds then in the Escrow Account and the manner in which such funds are invested
("Escrow Account Statement"). The parties hereto irrevocably instruct the Escrow
Agent that on the first date upon which the balance in the Escrow Account
(including the holdings of all U.S. Government Securities) is reduced to zero,
the Escrow Agent shall deliver to the Company and to the Trustee a notice that
the balance in the Escrow Account has been reduced to zero.

            3. Disbursements.

            (a) Payment Notice and Disbursement Request; Disbursements. The
Trustee shall, at least five business days prior to an Interest Payment Date,
submit to the Escrow Agent a completed Payment Notice and Disbursement Request
substantially in the form of Exhibit A hereto.

            The Escrow Agent's disbursement pursuant to any Payment Notice and
Disbursement Request shall be subject to the satisfaction of the applicable
conditions set forth in Section 3(b). Provided such Payment Notice and
Disbursement Request is not rejected by it, the Escrow Agent, as soon as
reasonably practicable on the Interest Payment Date, but in no event later than
12:00 Noon (New York City time) on the Interest Payment Date, shall disburse the
funds requested in such Payment Notice and Disbursement Request by wire or
book-entry transfer of immediately available funds to the account of the Trustee
for the benefit of the Beneficiaries. The Escrow Agent shall notify the Trustee
as soon as reasonably possible (but not later than two (2) business days from
the date of receipt of the Payment Notice and Disbursement Request) if any
Payment Notice and Disbursement Request is rejected and the reason(s) therefor.
In the event such rejection is based upon nonsatisfaction of the condition in
Section 3(b)(I) below, the Trustee shall thereupon resubmit the Payment Notice
and Disbursement Request with appropriate changes.

            (b) Conditions Precedent to Disbursement. The Escrow Agent's payment
of any disbursement shall be made only if: (I) the Trustee shall have submitted,
in accordance with the provisions of Section 3(a) herein, a completed Payment
Notice and Disbursement Request to the Escrow Agent substantially in the form of
Exhibit A with blanks appropriately filled in and (II) the Escrow Agent shall
not have received any notice from the Trustee that as a result of an Event of
Default the indebtedness represented by the Securities has been accelerated and
has become due and payable (in which event the Escrow Agent shall apply all
Available Funds as required by Section 6(b)(iii)).
<PAGE>
                                      -10-


            (c) Retired Securities. In the event a portion of the Securities has
been retired by the Company and submitted to the Trustee for cancellation and
there is no Default or Event of Default under the Indenture, funds representing
the lesser of (A) any funds remaining in the Escrow Account that are in excess
of the amount sufficient to pay interest through and including June 6, 2000 on
the Securities not so retired and (B) the interest payments which have not
previously been made on such retired Securities for each Interest Payment Date
through the Interest Payment Date to occur on June 6, 2000 shall, upon the
written request of the Company to the Escrow Agent and the Trustee, be paid to
the Company upon compliance with the release of collateral provisions of the TIA
and upon receipt by the Escrow Agent of a notice relating thereto from the
Trustee. 

            4. Escrow Agent.

            (a) Limitation of the Escrow Agent's Liability; Responsibilities of
the Escrow Agent. The Escrow Agent's responsibility and liability under this
Agreement shall be limited as follows: (i) the Escrow Agent does not represent,
warrant or guaranty to the holders of the Securities from time to time the
performance of the Company; (ii) the Escrow Agent shall have no responsibility
to the Company or the holders of the Securities or the Trustee from time to time
as a consequence of performance or non-performance by the Escrow Agent
hereunder, except for any gross negligence or willful misconduct of the Escrow
Agent; (iii) the Company shall remain solely responsible for all aspects of the
Company's business and conduct; and (iv) the Escrow Agent is not obligated to
supervise, inspect or inform the Company or any third party of any matter
referred to above.

            No implied covenants or obligations shall be inferred from this
Agreement against the Escrow Agent, nor shall the Escrow Agent be bound by the
provisions of any agreement beyond the specific terms hereof. Specifically and
without limiting the foregoing, the Escrow Agent shall in no event have any
liability in connection with its investment, reinvestment or liquidation, in
good faith and in accordance with the terms hereof, of any funds or U.S.
Government Securities held by it 
<PAGE>
                                      -11-


hereunder, including without limitation any liability for any delay not
resulting from gross negligence or willful misconduct in such investment,
reinvestment or liquidation, or for any loss of principal or income incident to
any such delay.

            The Escrow Agent shall be entitled to rely upon any judicial order
or judgment, upon any written opinion of counsel or upon any certification,
instruction, notice, or other writing delivered to it by the Trustee in
compliance with the provisions of this Agreement or by the Company, to the
extent not inconsistent with any instruction of the Trustee, in either case,
without being required to determine the authenticity or the correctness of any
fact stated therein or the propriety or validity of service thereof. The Escrow
Agent may act in reliance upon any instrument comporting with the provisions of
this Agreement or signature believed by it to be genuine and may assume that any
person purporting to give notice or receipt or advice or make any statement or
execute any document in connection with the provisions hereof has been duly
authorized to do so.

            At any time the Escrow Agent may request in writing an instruction
in writing from the Company, and may at its own option include in such request
the course of action it proposes to take and the date on which it proposes to
act, regarding any matter arising in connection with its duties and obligations
hereunder; provided, however, that the Escrow Agent shall state in such request
that it believes in good faith that such proposed course of action is consistent
with another identified provision of this Agreement. The Escrow Agent shall not
be liable to the Company for acting without the Company's consent in accordance
with such a proposal on or after the date specified therein if (i) the specified
date is at least two business days after the Company receives the Escrow Agent's
request for instructions and its proposed course of action, and (ii) prior to so
acting, the Escrow Agent has not received the written instructions requested
from the Company.

            The Escrow Agent may act pursuant to the written advice of counsel
chosen by it with respect to any matter relating to this Agreement and (subject
to clause (ii) of the first 
<PAGE>
                                      -12-


paragraph of this Section 4(a)) shall not be liable for any action taken or
omitted in accordance with such advice.

            The Escrow Agent shall not be called upon to advise any party as to
selling or retaining, or taking or refraining from taking any action with
respect to, any securities or other property deposited hereunder.

            In the event of any ambiguity in the provisions of this Agreement
with respect to any funds or property deposited hereunder, the Escrow Agent
shall be entitled to refuse to comply with any and all claims, demands or
instructions with respect to such funds or property, and the Escrow Agent shall
not be or become liable for its failure or refusal to comply with conflicting
claims, demands or instructions. The Escrow Agent shall be entitled to refuse to
act until either any conflicting or adverse claims or demands shall have been
finally determined by a court of competent jurisdiction or settled by agreement
between the conflicting claimants as evidenced in a writing, satisfactory to the
Escrow Agent, or the Escrow Agent shall have received security or an indemnity
satisfactory to the Escrow Agent sufficient to save the Escrow Agent harmless
from and against any and all loss, liability or expense which the Escrow Agent
may incur by reason of its acting. The Escrow Agent may in addition elect in its
sole option to commence an interpleader action or seek other judicial relief or
orders as the Escrow Agent may deem necessary.

            No provision of this Agreement shall require the Escrow Agent to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder.

            5. Indemnity. The Company shall indemnify, hold harmless and defend
the Escrow Agent and its directors, officers, agents, employees and controlling
persons, from and against any and all claims, actions, obligations, liabilities
and expenses, including defense costs, investigative fees and costs, legal fees,
and claims for damages, arising from the Escrow Agent's performance or
non-performance, or in connection with its acceptance or appointment as Escrow
Agent, under this 
<PAGE>
                                      -13-


Agreement, except to the extent that such liability, expense or claim is solely
and directly attributable to the gross negligence or willful misconduct of any
of the foregoing persons. The provisions of this Section 5 shall survive any
termination, satisfaction or discharge of this Agreement as well as the
resignation or removal of the Escrow Agent.

            6. Grant of Security Interest; Instructions to Escrow Agent. 

            (a) The Company hereby irrevocably grants a first priority security
interest in and lien on, and pledges, assigns and sets over to the Trustee for
the ratable benefit of the Beneficiaries, all of the Company's right, title and
interest in the Escrow Account, and all property now or hereafter placed or
deposited in, or delivered to the Escrow Agent for placement or deposit in, the
Escrow Account, including, without limitation, all funds held therein, all U.S.
Government Securities held by (or otherwise maintained in the name of) the
Escrow Agent pursuant to Section 2, and all proceeds thereof as well as all
rights of the Company under this Agreement (collectively, the "Collateral"), in
order to secure all obligations and indebtedness of the Company under the
Indenture, the Securities and any other obligation, now or hereafter arising, of
every kind and nature, owed by the Company under the Indenture to the holders of
the Securities or to the Trustee or any predecessor Trustee. The Escrow Agent
hereby acknowledges the Trustee's security interest and lien as set forth above.
The Company shall take all actions necessary on its part to insure the
continuance of a first priority security interest in the Collateral in favor of
the Trustee in order to secure all such obligations and indebtedness.

            (b) The Company and the Trustee hereby irrevocably instruct the
Escrow Agent to, and the Escrow Agent shall: (i) (A) maintain sole dominion and
control over funds and U.S. Government Securities in the Escrow Account for the
benefit of the Trustee to the extent specifically required herein, (B) maintain,
or cause its agent within the State of New York to maintain, possession in New
York of all certificated U.S. Government Securities purchased hereunder that are
physically pos-
<PAGE>
                                      -14-


sessed by the Escrow Agent in order for the Trustee to enjoy a continuous
perfected first priority security interest therein under the law of the State of
New York (the Company hereby agreeing that in the event any certificated U.S.
Government Securities are in the possession of the Company or a third party, the
Company shall use its best efforts to deliver all such certificates to the
Escrow Agent), (C) take all steps specified by the Company pursuant to paragraph
(a) of this Section 6 to cause the Trustee to enjoy a continuous perfected first
priority security interest under any applicable Federal and State of New York
law in all U.S. Government Securities purchased hereunder that are not
certificated and (D) maintain the Collateral free and clear of all liens,
security interests, safekeeping or other charges, demands and claims against the
Escrow Agent of any nature now or hereafter existing in favor of anyone other
than the Trustee; (ii) promptly notify the Trustee if a responsible officer of
the Escrow Agent receives written notice that any Person other than the Trustee
has a lien or security interest upon any portion of the Collateral; and (iii) in
addition to disbursing amounts held in escrow pursuant to any Payment Notice and
Disbursement Requests given to it by the Trustee pursuant to Section 3, upon
receipt of written notice from the Trustee of the acceleration of the maturity
of the Securities, and direction from the Trustee to disburse all Available
Funds to the Trustee, as promptly as practicable, after following, if it so
chooses, the procedures set forth in the fourth paragraph of Section 4(a),
disburse all funds held in the Escrow Account to the Trustee and transfer title
to all U.S. Government Securities held by the Escrow Agent hereunder to the
Trustee. The lien and security interest provided for by this Section 6 shall
automatically terminate and cease as to, and shall not extend or apply to, and
the Trustee shall have no security interest in, any funds disbursed by the
Escrow Agent to the Company pursuant to this Agreement to the extent not
inconsistent with the terms hereof. Notwithstanding any other provision
contained in this Agreement, the Escrow Agent shall act solely as the Trustee's
agent for purposes of holding and perfecting the Trustee's security interest in
the Collateral in connection with its duties under this Section 6 or any other
duties herein relating to the Escrow Account or any funds or 
<PAGE>
                                      -15-


U.S. Government Securities held thereunder. The Escrow Agent shall not have any
right to receive compensation from the Trustee and shall have no authority to
obligate the Trustee or to compromise or pledge its security interest hereunder.
Accordingly, the Escrow Agent is hereby directed to cooperate with the Trustee
in the exercise of its rights in the Collateral provided for herein.

            (c) Any money and U.S. Government Securities collected by the
Trustee pursuant to Section 6(b)(iii) shall be applied as provided in Section
5.06 of the Indenture. Any surplus of such cash or cash proceeds held by the
Trustee and remaining after indefeasible payment in full of all the obligations
under the Indenture shall be paid over to the Company or to whomsoever may be
lawfully entitled to receive such surplus or as a court of competent
jurisdiction may direct.

            (d) Upon demand, the Company will execute and deliver to the Trustee
such instruments and documents as the Trustee may deem necessary or advisable to
confirm or perfect the rights of the Trustee under this Agreement and the
Trustee's interest in the Collateral. The Trustee shall be entitled to take all
necessary action to preserve and protect the security interest created hereby as
a lien and encumbrance upon the Collateral.

            (e) The Company hereby appoints the Trustee as its attorney-in-fact
with full power of substitution to do any act which the Company is obligated
hereto to do, and the Trustee may exercise such rights as the Company might
exercise with respect to the Collateral and take any action in the Company's
name to protect the Trustee's security interest hereunder. In addition to the
rights provided under Section 6(b)(iii) hereof, upon an Event of Default as
defined in the Indenture and for so long as such Event of Default continues, the
Trustee may exercise in respect of the Collateral, in addition to other rights
and remedies provided for herein or otherwise available to it, all the rights
and remedies of a secured party under the UCC or other applicable law, and the
Trustee may also upon obtaining possession of the Collateral as set forth
herein, without notice to the Company except as specified below, sell the
Collat-
<PAGE>
                                      -16-


eral or any part thereof in one or more parcels at public or private sale, at
any exchange, broker's board or at any of the Trustee's offices or elsewhere,
for cash, on credit or for future delivery, and upon such other terms as the
Trustee may deem commercially reasonable. The Company acknowledges and agrees
that any such private sale may result in prices and other terms less favorable
to the seller than if such sale were a public sale. The Company agrees that, to
the extent notice of sale shall be required by law, at least ten (10) days'
notice to the Company of the time and place of any public sale or the time after
which any private sale is to be made shall constitute reasonable notification.
The Trustee shall not be obligated to make any sale regardless of notice of sale
having been given. The Trustee may adjourn any public or private sale from time
to time by announcement at the time and place fixed therefor, and such sale may,
without further notice, be made at the time and place to which it was so
adjourned.

            7. Termination. This Agreement shall terminate automatically ten
(10) days following disbursement of all funds remaining in the Escrow Account
(including U.S. Government Securities), unless sooner terminated by agreement of
the parties hereto (in accordance with the terms hereof and not in violation of
the Indenture; provided, that the Trustee may not agree to terminate unless it
has received the consent of 100% of the holders of all of the Securities
outstanding); provided, however, that the obligations of the Company under
Section 2(c) and Section 5 (and any existing claims thereunder) shall survive
termination of this Agreement and the resignation of the Escrow Agent; provided,
further, however, that until such tenth day, the Company will cause this
Agreement (or any permitted successor agreement) to remain in effect and will
cause there to be an escrow agent (including any permitted successor thereto)
acting hereunder (or under any such permitted successor agreement).

            8. Miscellaneous.

            (a) Waiver. Any party hereto may specifically waive any breach of
this Agreement by any other party, but no such waiver shall be deemed to have
been given unless such waiver is 
<PAGE>
                                      -17-


in writing, signed by the waiving party and specifically designating the breach
waived, nor shall any such waiver constitute a continuing waiver of similar or
other breaches.

            (b) Invalidity. If for any reason whatsoever any one or more of the
provisions of this Agreement shall be held or deemed to be inoperative,
unenforceable or invalid in a particular case or in all cases, such
circumstances shall not have the effect of rendering any of the other provisions
of this Agreement inoperative, unenforceable or invalid, and the inoperative,
unenforceable or invalid provision shall be construed as if it were written so
as to effectuate, to the maximum extent possible, the parties' intent.

            (c) Assignment. This Agreement is personal to the parties hereto,
and the rights and duties of any party hereunder shall not be assignable except
with the prior written consent of the other parties. Notwithstanding the
foregoing, this Agreement shall inure to and be binding upon the parties and
their successors and permitted assigns.

            (d) Benefit. The parties hereto and their successors and permitted
assigns, but no others, shall be bound hereby and entitled to the benefits
hereof; provided, however, that the Beneficiaries (including holders of the
Securities) and their assigns or successors in interest shall be entitled to the
benefits hereof and to enforce this Agreement.

            (e) Time. Time is of the essence with respect to each provision of
this Agreement.

            (f) Entire Agreement; Amendments. This Agreement and the Indenture
contain the entire agreement among the parties with respect to the subject
matter hereof and supersede any and all prior agreements, understandings and
commitments, whether oral or written. This Agreement may be amended only in
accordance with Article Nine of the Indenture and further by a writing signed by
a duly authorized representative of each party hereto.

to be paid in cash shall have been paid or declared and a sum set apart
sufficient for the payment thereof, and (ii) unless, if at any time the
Corporation is obligated to retire Preferred Stock pursuant to any mandatory
redemption requirement, sinking fund or a fund of a similar nature, all arrears,
if any, in respect of the retirement of the Preferred Stock shall have been made
good. Subject to the foregoing provisions and not otherwise, such dividends
(payable in cash, stock or otherwise) as may be determined by the Shareholders'
Meeting may be declared and paid on the Common Stock from time to time out of
the remaining funds of the Corporation legally available therefor, and the
Preferred Stock shall not be entitled to participate in any such dividend,
whether payable in cash, stock or otherwise.

      (c)   Rights on Liquidation.

               (i) Priority on Liquidation. In the event of any liquidation,
      dissolution or winding up of the Corporation, whether voluntary or
      involuntary, then, before any distribution or payment shall be made to the
      holders of the Common Stock, the holders of the Preferred Stock shall be


                                      -5-
<PAGE>

      entitled to be paid an amount per Share equal to U.S. $1,000 Dollars or
      its equivalent in Reais or other currency, plus an amount equal to any and
      all dividends accrued and unpaid thereon as of the date of such
      distribution or payment (the "Preferred Priority"). If, upon any
      liquidation, dissolution or winding up of the Corporation, the assets to
      be distributed to the holders of the Preferred Stock shall be insufficient
      to permit the payment to such holders of the full Preferred Priority, then
      all of the assets of the Corporation shall be distributed ratably to the
      holders of the Preferred Stock based on the aggregate Preferred Priority
      for the shares of Preferred Stock held by each holder.

              (ii) Distribution of Remaining Assets. If such payment of the
      Preferred Priority shall have been made in full to the holders of the
      Preferred Stock, the remaining assets and funds of the Corporation, if
      any, shall be distributed among the holders of the Common Stock according
      to their respective equity investment.

             (iii) Merger or Sale of Assets. A consolidation or merger of the
      Corporation with or into any other corporation or other entity in which
      the holders of the Corporation's outstanding Common Stock before the
      merger or consolidation do not retain a majority of the voting power of
      the surviving corporation or other entity, or a sale of all or
      substantially all of the assets of the Corporation, shall be deemed to be
      a liquidation, dissolution or winding up of the Corporation as those terms
      are used in this Clause 3.1(c).

              (iv) Non-Cash Consideration. In the event that such distribution
      to the holders of Preferred Stock shall include any assets other than
      cash, the following provisions shall govern. The Shareholders owning
      Common Stock shall first determine the fair market value of such assets
      for such purpose, and shall notify all holders of Preferred Stock of such
      determination. The fair market value of such assets for purposes of the
      distribution under this subsection shall be the fair market value as
      determined by a majority vote of the Shareholders in good faith, unless
      the holders of a majority of the outstanding Preferred Stock shall object
      thereto in writing within fifteen (15) days after the date of such notice.
      In the event of such objection, the valuation of such assets for purposes
      of such distribution shall be determined by an arbitrator selected by the
      objecting Shareholders and the other Shareholders, or in the event a
      single arbitrator cannot be agreed upon within ten (10) days after the
      written objection sent by the objecting Shareholders in accordance with
      the previous sentence, the valuation of such assets shall be determined by
      arbitration in which (A) the objecting Shareholders shall name in their
      notice of objection one arbitrator, (B) the other Shareholders shall name
      a second arbitrator within fifteen 


                                      -6-
<PAGE>

      (15) days from the receipt of such notice, (C) the two arbitrators thus
      selected shall select a third arbitrator within fifteen (15) days
      thereafter, and (D) the three arbitrators thus selected shall determine
      the valuation of such assets within fifteen (15) days thereafter for
      purposes of such distribution by majority vote. In the event the second or
      third arbitrator is not selected as provided herein, then such arbitrator
      shall be selected by the President of the American Arbitration Association
      ("AAA"). The costs of such arbitration shall be borne by the Corporation
      or by the holders of Preferred Stock (on a pro rata basis out of the
      assets otherwise distributable to them) as follows: (A) if the valuation
      as determined by the arbitrators is greater than ninety percent (90%) of
      the valuation as determined by the Shareholders, the holders of Preferred
      Stock shall pay the costs of the arbitration, and (B) otherwise, the
      Corporation shall bear the costs of the arbitration. The arbitration shall
      be held in New York, New York in accordance with the International
      Arbitration Rules of the AAA. The award made by the arbitrators shall be
      binding upon the parties hereto, no appeal shall be taken from such award
      and judgment thereon may be entered in any court of competent jurisdiction
      to the extent permitted by such jurisdiction.

      (d)   Redemption.

               (i) At the election of the holders of a majority of the
      outstanding Preferred Stock, made by written notice to the Corporation,
      the Preferred Stock shall be subject to mandatory redemption (to the
      extent that such redemption shall not violate any applicable provisions of
      the laws of Brazil, based upon the advice of counsel) at a price per share
      equal to U.S. $1,000, plus an amount equal to any and all dividends
      accrued and unpaid thereon as of the date of such redemption (the
      "Redemption Price") as follows:

            (A) if the Corporation defaults in the performance of or compliance
            with any term contained herein and such default is not remedied
            within thirty (30) days after the earlier of (1) a Responsible
            Officer obtaining actual knowledge of such default and (2) the
            Corporation receiving written notice of such default from any
            Preferred Stock holder; or

            (B) if a Material  Adverse  Change (as  defined in the  Securities
            Subscription Agreement) occurs; or

            (C) if a Liquidity Event (as defined in the Securities Subscription
            Agreement) occurs.

              (ii) On the tenth anniversary of the date of issuance of Preferred
      Stock pursuant to the Securities Subscription Agreement, all shares of
      Preferred Stock then 


                                      -7-
<PAGE>

      outstanding shall be redeemed at the per share price equal to the
      Redemption Price.

             (iii) If the Corporation is unable to redeem any shares of
      Preferred Stock because such redemption would violate the applicable laws
      of Brazil, then the Corporation shall redeem such shares to the extent
      possible on a pro rata basis and thereafter as soon thereafter as the
      restrictions precluding such redemption shall no longer be applicable.

              (iv) In case of redemption of only part of the shares of Preferred
      Stock at any time outstanding, the shares to be redeemed shall be selected
      pro rata (as nearly as may be) from all holders in proportion to the
      number of shares of Preferred Stock held by each of them, except as may be
      required by applicable law. Notice of every redemption provided for in
      this Clause 3.1(d) shall be given by as provided in Clause 12(e) to every
      holder of record, any of whose shares are then to be redeemed, not less
      than 15 nor more than 30 days prior to the date fixed as the date of the
      redemption thereof, at the respective addresses of such holders as the
      same shall appear on the stock transfer books of the Corporation. The
      notice shall state that the shares specified in such notice will be
      redeemed by the Corporation at the Redemption Price and on the date
      specified in such notice, accompanied by cash or a certified check in the
      amount of any stock transfer tax applicable to such transaction. On and
      after the date specified in the notice described above, each holder of
      shares called for redemption shall be entitled to receive therefor the
      applicable Redemption Price. If the Corporation shall give notice of
      redemption as aforesaid (and unless the Corporation shall fail to pay the
      Redemption Price in accordance with such notice), all shares called for
      redemption shall be deemed to have been redeemed on the date specified in
      such notice, and such shares so called for redemption shall from and after
      such date cease to represent any interest whatever in the Corporation or
      its property, and the holders thereof shall have no rights other than the
      right to receive such Redemption Price but without any interest thereon
      from or after such date.

               (v) Cancellation of Redeemed Shares. All shares of the Preferred
      Stock purchased or redeemed by the Corporation shall be forthwith retired
      and canceled and shall not be reissued, nor shall any other stock be
      issued in place thereof, but the Corporation may, nevertheless, from time
      to time thereafter increase its capital stock in the manner and to the
      extent permitted by law and by the Corporation's bylaws.

      (e) Voting Rights. The Preferred Stock shall be entitled to vote as a
class in connection with the matters set forth in 


                                      -8-

of Directors and out of funds legally available therefor. Holders of Common
Stock shall be entitled to share equally, share for share, in such dividends.
The holders of Common Stock hereby agree to the accumulation and non-payment of
dividends for a period of ten (10) years from the date hereof or until the
redemption of the Preferred Stock, whichever occurs earlier.

      (b) Liquidation. In the event of any liquidation, dissolution or winding
up of the affairs of the Corporation, voluntary or involuntary, after payment or
provision for payment to the holders of Preferred Stock of the amounts to which
they may be entitled as set out above, the remaining assets of the Corporation
available to Shareholders shall be distributed equally per share to the holders
of Common Stock.

      (c) Voting Rights. Each share of Common Stock shall be entitled to one
vote in the Shareholders' Meeting.

                  indebtedness  and which do not in the  aggregate  materially
                  interfere  with  the use or value  of such  property  in the

      (a) Resale of Securities.

            (i) No Shareholder shall Transfer any Securities other than in
      accordance with the provisions of this Clause 8. Any Transfer or purported
      Transfer made in violation of this Clause 8 shall be null and void and of
      no effect. For purposes of this Clause 8, the term Common Stock shall
      include any subscription bonds or options to acquire shares of Common
      Stock.

            (ii) For a period commencing on the Closing Date and ending on the
      20th annual anniversary thereof, no Shareholder will sell or otherwise
      Transfer its Securities without the prior written approval of Warburg,
      which approval will not be unreasonably withheld. The foregoing
      restriction shall not apply to Transfers to such Shareholder's Affiliates,
      which Affiliates agree in writing to be bound by all restrictions
      applicable to the transferring Shareholder or to Transfers to Directors as
      Directors' qualifying shares. Notwithstanding the foregoing, after the
      fifth anniversary of the date hereof, each of IPC and Multiponto shall be
      permitted to Transfer Common or Preferred Stock owned by it without the
      prior written approval of Warburg, provided that any such Transfer shall
      be subject to the provisions of Clause 8(b)(i).

            (iii) No Management Investor will sell or otherwise Transfer any of
      his or her Common Stock for a period of five (5) years from the date on
      which such Common Stock is no longer subject to forfeiture (pursuant to
      the Subscription Agreement between the Corporation and such Management
      Investor pursuant to which such Common Stock was acquired) without the
      prior written approval of the Board, which approval will not be
      unreasonably withheld. The foregoing restriction shall not apply to
      Transfers (A) to members of such Management Investor's family or trusts
      for the benefit of such Management Investor or such Management Investor's
      family; provided in each instance that such transferee agrees to be bound
      by the provisions of this Agreement as if such transferee were an original
      signatory hereto and (B) pursuant to the terms of Section 11 of the
      Employment Agreement between the Corporation and such Management Investor.

      (b) Right of First Offer.

            (i) No Shareholder shall Transfer any of the Securities owned by it
      (except for Transfers to one of its Affiliates, provided in each instance
      that such Affiliate agrees to be bound by the provisions of this Agreement
      as if such Affiliate were an original signatory hereto) unless the
      Shareholder desiring to make the Transfer (hereinafter 


                                      -20-
<PAGE>

      referred to as the "Transferor") shall have first provided notice of such
      intention to Transfer pursuant to Clause 8(b)(1)(A).

                  (A) Offer by PageNet. In the event the Transferor wishes to
            Transfer any of its Securities (the securities proposed to be
            transferred being referred to as the "Subject Securities"), it shall
            provide written notice of such intention to PageNet. PageNet shall,
            within thirty (30) days of the date of such notice (i) irrevocably
            offer in writing to purchase the Subject Securities for an amount
            (the "Offer Price") as may be specified by PageNet (the "Offer") or
            (ii) inform the Transferor in writing that it does not wish to
            purchase the Subject Securities. In the event PageNet fails to
            comply with the preceding sentence within such 30-day period, it
            shall be deemed to have waived its right to offer to purchase the
            Subject Securities. The Offer shall not contain any material
            conditions (other than the receipt of all required consents and
            approvals) and shall specify a date for the closing of the purchase
            which shall not be more than thirty (30) days after the later of the
            giving of such notice or the receipt of all required consents and
            approvals. The Corporation, PageNet and the Transferor agree to use
            their best efforts to obtain all required consents and approvals
            promptly.

                  (B) Acceptance of Offer. Within 10 business days after the
            receipt of the Offer, the Transferor may, at its option, accept the
            Offer by giving written notice thereof to PageNet.

                  (C) Closing of Purchase. In the event the Transferor accepts
            the Offer, the closing of the purchase shall take place at the
            office of the Corporation or such other location as shall be
            mutually agreed upon and the purchase price shall be paid at the
            closing. At the closing, the Transferor shall deliver to PageNet all
            instruments required to transfer the Subject Securities.

                  (D) Release from Restriction; Termination of Rights. If
            PageNet fails to make an Offer in accordance with Clause 8(b)(i)(A),
            the Transferor shall be free to Transfer the Subject Securities
            without restriction. If PageNet makes an Offer that is not accepted
            by the Transferor, the Transferor shall disclose to PageNet the
            terms of each offer (including the identity of the offeror) received
            by the Transferor in respect of the Subject Securities and shall
            thereafter be entitled to Transfer the Subject Securities to a third
            party at a price equal to or greater than the Offer Price (and
            subject to no 


                                      -21-
<PAGE>

            material conditions other than regulatory approvals and those
            contained in PageNet's offer, except as otherwise provided in this
            Clause 8(b)(i)(D)); provided that the transferee agrees, in writing,
            to be bound by the provisions of this Agreement. If the Transferor
            shall fail to Transfer the Subject Securities within 180 days
            following the date on which the Transferor receives the Offer or, if
            no Offer is received, the last day on which PageNet was entitled to
            make the Offer, such Subject Securities shall again become subject
            to all the restrictions of this Clause 8. Any Transfer by Warburg
            pursuant to this Clause 8(b)(i) shall be subject to the provisions
            of Clause 8(d) hereof.

                  (E) Right to Match Offer. Notwithstanding the provisions of
            Clause 8(b)(i)(D), if the offer price received by the Transferor in
            connection with a third party offer is no more than seven and
            one-half percent (7.5%) greater than the offer price of the Offer
            made by PageNet, then PageNet shall have the right, within ten (10)
            business days after the Transferor notifies PageNet of such third
            party offer, to make an Offer that matches the offer price and is on
            terms as favorable as the third party offer. If PageNet makes such
            an Offer, such Offer shall be accepted by the Transferor.

              (ii) Neither the Corporation nor any of its Subsidiaries shall
      Transfer all or substantially all of the assets of the Corporation and its
      Subsidiaries, taken as a whole (the "Corporation Assets"), unless it shall
      have first provided notice of such intention to effect such Transfer
      pursuant to Clause 8(b)(ii)(A).

                  (A) Offer by PageNet. In the event the Corporation or any of
            its Subsidiaries (hereinafter referred to as an "Asset Transferor")
            wishes to Transfer the Corporation Assets, it shall provide written
            notice of such intention to PageNet. PageNet shall, within thirty
            (30) days of the date of such notice (i) irrevocably offer in
            writing to purchase the Corporation Assets for an amount (the "Asset
            Offer Price") as may be specified by PageNet (the "Asset Offer") or
            (ii) inform the Corporation in writing that it does not wish to
            purchase the Corporation Assets. In the event PageNet fails to
            comply with the preceding sentence within such 30-day period, it
            shall be deemed to have waived its right to offer to purchase the
            Corporation Assets. The Asset Offer shall not contain any material
            conditions (other than the receipt of all required consents and
            approvals and those that would be required by any purchaser) and
            shall specify a date for the closing of the purchase which shall not
            be more than thirty (30) days after the later of the giving of 


                                      -22-
<PAGE>

            such notice or the receipt of all required consents and approvals.
            The Corporation, its Subsidiaries and PageNet agree to use their
            best efforts to obtain all required consents and approvals promptly.

                  (B) Acceptance of Offer. Within ten (10) business days after
            the receipt of the Asset Offer, the Asset Transferor may, at its
            option, accept the Asset Offer by giving written notice thereof to
            PageNet.

                  (C) Closing of Purchase. In the event the Asset Transferor
            accepts the Asset Offer, the closing of the purchase shall take
            place at the office of the Corporation or such other location as
            shall be mutually agreed upon and the purchase price shall be paid
            at the closing. At the closing, the Asset Transferor shall deliver
            to PageNet all certificates, instruments and other documents
            necessary to effectuate the transfer and conveyance of the
            Corporation Assets.

                  (D) Release from Restriction, Termination of Rights. If
            PageNet fails to make an Asset Offer in accordance with Clause
            8(b)(ii)(A), the Asset Transferor shall be free to Transfer the
            Corporation Assets without restriction. If PageNet makes an Asset
            Offer that is not accepted by the Asset Transferor, the Asset
            Transferor shall disclose the terms of each offer (including the
            identity of the offeree) received by it in respect of the
            Corporation Assets and shall thereafter be entitled to Transfer the
            Corporation Assets to a third party at a price equal to or greater
            than the Asset Offer Price (and subject to no material conditions
            other than regulatory approvals and those imposed by PageNet). If
            the Asset Transferor shall fail to Transfer the Corporation Assets
            within 180 days following the date on which it receives the Asset
            Offer or, if no Asset Offer is received, the last day on which
            PageNet was entitled to make the Asset Offer, such the Corporation
            Assets shall again become subject to all the restrictions of this
            Clause 8.

                  (E) Right to Match Offer. Notwithstanding the provisions of
            Clause 8(b)(ii)(D), if the offer price received by the Asset
            Transferor in connection with a third party offer is no more than
            seven and one-half percent (7.5%) greater than the offer price of
            the Asset Offer made by PageNet, then PageNet shall have the right,
            within ten (10) business days after the Asset Transferor notifies
            PageNet of such third party offer, to make an Asset Offer that
            matches the offer price and is on terms as favorable as the third
            party offer. If PageNet makes such an Offer, such Offer shall be
            accepted by the Asset Transferor.

             (iii) For purposes of Clause 8(b)(i) and (b)(ii) above, if the
      consideration to be received by the Transferor or the Asset Transferor is
      other than cash, indebtedness or securities, the value of such
      consideration shall be its fair market value. Any securities offered as
      consideration shall be valued as follows:

                  (A) If traded on a national securities exchange, the value
            shall be deemed to be the average of the closing prices of the
            securities on such exchange over the 30-day period ending three (3)
            days prior to the closing; and

                  (B) If actively traded over-the-counter, the value shall be
            deemed to be the average of the daily averages of the closing bid
            and asked prices over the 30-day period ending three (3) days prior
            to the closing; and

                  (C) If there is no active public market, the value shall be
            the fair market value thereof, as determined in good faith by the
            Transferor or the Asset Transferor, as the case may be; provided,
            however, that in the event any such securities are subject to
            investment letter or similar restrictions on free marketability,
            such securities shall reflect an appropriate discount from the
            market value determined pursuant to paragraphs (A), (B) or (C) of
            this clause to reflect the fair market value thereof, as determined
            in good faith by the Transferor or the Asset Transferor, as the case
            may be.

              (iv)   Neither  Warburg,  Pincus & Co. nor any of its Affiliates
      will  Transfer  its equity  interest  in Warburg if the sole  purpose of
      such Transfer is to circumvent the provisions of this Clause 8(b).

               (v) None of TVA, IPC or Multiponto nor any Affiliate thereof
      having an ownership interest (direct ownership in the case of a general
      partner of a partnership and indirect ownership in the case of a limited
      partner of a limited partnership) in the Corporation will undergo a Change
      of Control without providing prior written notice of such Change of
      Control to PageNet, which shall notify PageNet of all of the facts and
      circumstances surrounding such Change of Control. If such a Change of
      Control of TVA, IPC or Multiponto, as the case may be, or any such
      Affiliate shall have occurred without advance notice to TVA, IPC or
      Multiponto, as the case may be, or such Affiliate, IPC shall provide such
      notice of Change of Control as soon as practicable after becoming aware of
      it. Within thirty (30) days of the date of such notice, PageNet shall have
      the right, exercisable by written notice (the "Call Notice") to TVA, IPC
      or Multiponto, as the case may be, and such 


                                      -24-
<PAGE>

      Affiliates (the "Callees") to purchase itself or cause to be purchased at
      the purchase price set forth below, all but not less than all of the
      Securities owned by the Callees, on such date that is the later of thirty
      (30) days following the Call Notice, or thirty (30) days after the later
      of the date on which all required consents and approvals have been
      received, or such shorter time as may be specified by PageNet in the Call
      Notice. The purchase price to be paid by PageNet shall be the Fair Market
      Value of the Securities, without regard to the Change of Control, on the
      date the Call Notice is given. For purposes of this clause (iv), "Fair
      Market Value" means the value as determined by PageNet in good faith and
      with due care, unless TVA, IPC or Multiponto, as the case may be, shall
      object thereto in writing within 15 days after the date of such Call
      Notice. In the event of such objection, the Fair Market Value shall be
      determined by an arbitrator selected by PageNet and TVA, IPC or
      Multiponto, as the case may be, in the event a single arbitrator cannot be
      agreed upon within 10 days after the written objection sent by TVA, IPC or
      Multiponto, as the case may be, in accordance with the previous sentence,
      the Fair Market Value shall be determined by arbitration in which (1) TVA,
      IPC or Multiponto, as the case may be, shall name in its notice of
      objection one arbitrator, (2) PageNet shall name a second arbitrator
      within 15 days from the receipt of such notice, (3) the two arbitrators
      thus selected shall select a third arbitrator within 15 days thereafter,
      and (4) the three arbitrators thus selected shall determine the Fair
      Market Value within 15 days thereafter by majority vote. In the event the
      third arbitrator is not selected as provided herein, then such arbitrator
      shall be selected by the President of the AAA. The costs of such
      arbitration shall be borne by PageNet or TVA, IPC or Multiponto, as the
      case may be, as follows: (1) if the Fair Market Value determined by the
      arbitrators is greater than 90% of the Fair Market Value as determined by
      PageNet, then any of TVA, IPC or Multiponto, as the case may be, shall pay
      the costs of the arbitration, and (2) otherwise, PageNet shall bear the
      costs of the arbitration. The arbitration shall be held in New York, New
      York in accordance with the International Arbitration Rules of the AAA.
      The award made by the arbitrators shall be binding upon the parties
      hereto, no appeal shall be taken from such award and judgment thereon may
      be entered in any court of competent jurisdiction. For purposes of this
      Clause 8(b)(v), a "Change of Control" shall occur upon the earlier of (1)
      a Person or group of affiliated or associated Persons (an "Acquiring
      Person") (in the case of IPC, not including any existing shareholder, or
      employee or group of shareholders or group of employees of IPC's general
      partner) having acquired beneficial ownership of 50% or more of the
      outstanding 


                                      -25-
<PAGE>

      equity securities or equity interests of TVA, IPC or Multiponto, as the
      case may be, or such Affiliate (or, in the case of IPC, 50% or more of the
      outstanding equity securities or equity interests of the general partner
      of such entity or any such Affiliate) or a public announcement or
      knowledge by TVA, IPC or Multiponto, as the case may be, or any such
      Affiliate that an Acquiring Person intends to acquire beneficial ownership
      of 50% or more of such outstanding equity securities or equity interests,
      or, in the case of any other Investor or such Affiliate organized as a
      partnership or limited liability company, a change in the majority control
      of a general or managing partner, of such Investor or Affiliate; or (2)
      immediately following the commencement of, or announcement of an intention
      to make, a tender offer or exchange offer the consummation of which would
      result in the beneficial ownership by a person or group of 50% or more of
      such outstanding equity securities or equity interests.

      (c) Tag-Along Rights for Management Investors.

            (i) In the event the Shareholders, acting together, intend to
      Transfer one hundred percent (100%) of their shares of Common Stock, they
      shall notify the Management Investors, in writing, of such proposed
      Transfer and its terms and conditions. Within ten (10) business days of
      the date of such notice, each Management Investor shall notify the
      Shareholders if he or she elects to participate in such Transfer. Each
      Management Investor who so notifies the Shareholders shall have the right
      to sell, at the same price and on the same terms and conditions as the
      Shareholders, all (but not less than all) of his or her shares of Common
      Stock. Any Transfer by the Shareholders pursuant to this Clause 8(c) shall
      be subject to the provisions of Clause 8(b) hereof.

            (ii) Notwithstanding anything contained in this Clause 8(c), in the
      event that all or a portion of the purchase price consists of securities
      and the sale of such securities to the Management Investors would require
      either a registration under any securities laws or the preparation of a
      disclosure document, then, at the option of the Shareholders, the
      Management Investors may receive, in lieu of such securities, the fair
      market value of such securities in cash, as determined in good faith by
      the Board under this Clause 8(d). Any transfer by the Shareholders
      pursuant to this Clause 8(d) shall be subject to the provisions of Clause
      8(b) hereof.

      (d) Tag-Along Rights of Shareholders.

            (i) In the event any Shareholder intends to Transfer its shares of
      Common Stock (a "Selling Shareholder") (other than to an Affiliate of such
      Selling Shareholder), such Selling Shareholder shall notify the other
      Shareholders, in writing, of such proposed Transfer and its terms and
      conditions. Within thirty (30) days of 


                                      -26-
<PAGE>

      the date of such notice, each Shareholder shall notify the Selling
      Shareholder if it elects to participate in such Transfer. Each Shareholder
      that so notifies the Selling Shareholder shall have the right to sell, at
      the same price and on the same terms and conditions as the Selling
      Shareholder, an amount of shares equal to the shares of Common Stock the
      third party actually proposes to purchase multiplied by a fraction, the
      numerator of which shall be the number of shares of Common Stock issued
      and owned by such Shareholder and the denominator of which shall be the
      aggregate number of shares of Common Stock issued and owned by the Selling
      Shareholder and each Shareholder exercising its rights under this Clause
      8(d). Any Transfer by the Shareholders pursuant to this Clause 8(d) shall
      be subject to the provisions of Clause 8(b) hereof.

              (ii) In the event the Selling Shareholder intends to Transfer its
      Preferred Stock (other than to an Affiliate of the Selling Shareholder),
      the Selling Shareholder shall notify the other Shareholders, in writing,
      of such proposed Transfer and its terms and conditions. Within thirty (30)
      days of the date of such notice, each Shareholder shall notify the Selling
      Shareholder if it elects to participate in such Transfer. Each Shareholder
      that so notifies the Selling Shareholder shall have the right to sell, at
      the same price and on the same terms and conditions as the Selling
      Shareholder, a number of shares of Preferred Stock equal to the aggregate
      number of shares of Preferred Stock the third party actually proposes to
      purchase multiplied by a fraction, the numerator of which shall be the
      aggregate number of shares of Preferred Stock owned by such Shareholder
      and the denominator of which shall be the aggregate number of shares of
      Preferred Stock owned by the Selling Shareholder and each Shareholder
      exercising its rights under this Clause 8(d). Any Transfer by the
      Shareholders pursuant to this Clause 8(d) shall be subject to the
      provisions of Clause 8(b) hereof.

             (iii) Notwithstanding anything contained in this Clause 8(d), in
      the event that all or a portion of the purchase price consists of
      securities and the sale of such securities to the Shareholders would
      require either a registration under any securities laws or the preparation
      of a disclosure document, then, at the option of the Selling Shareholder,
      the Shareholders may receive, in lieu of such securities, the fair market
      value of such securities in cash, as determined in good faith by the
      Board.

      (e) Drag-Along Right.

               (i) Subject to the provisions of Clause 8(b), if at any time and
      from time to time after the date of this Agreement, Warburg wishes to
      Transfer in a bona fide arms' length sale all of its shares of Common
      Stock or Preferred 


                                      -27-
<PAGE>

      Stock to any Person or Persons who are not Affiliates of Warburg (for
      purposes of this Clause 8(e), the "Proposed Transferee"), Warburg shall
      have the right (for purposes of Clause 8(e), the "Drag-Along Right") to
      require each Shareholder to sell to the Proposed Transferee all of the
      shares of Common Stock (including any subscription rights or options to
      acquire Common Stock) or Preferred Stock, as applicable (for the same per
      share consideration as proposed to be received by Warburg) then owned by
      such Shareholder. Each Shareholder agrees to take all steps necessary to
      enable him or it to comply with the provisions of this Clause 8(e) to
      facilitate Warburg's exercise of a Drag-Along Right.

              (ii) To exercise a Drag-Along Right, Warburg shall give each
      Shareholder a written notice (for purposes of this Clause 8(e), a
      "Drag-Along Notice") containing (1) the name and address of the Proposed
      Transferee and (2) the proposed purchase price, terms of payment and other
      material terms and conditions of the Proposed Transferee's offer. Each
      Shareholder shall thereafter be obligated to sell the shares of Common
      Stock (including shares of Common Stock issuable upon exercise of any
      subscription rights or options held directly or indirectly by such
      Shareholder), and/or, if applicable, Preferred Stock subject to such
      Drag-Along Notice; provided that the sale to the Proposed Transferee is
      consummated within ninety (90) days of delivery of the Drag-Along Notice.
      If the sale is not consummated within such 90-day period, then each
      Shareholder shall no longer be obligated to sell such Shareholder's shares
      pursuant to that specific Drag Along Right, but shall remain subject to
      the provisions of this Clause 8(e).

             (iii) Notwithstanding anything contained in this Clause 8(e), in
      the event that all or a portion of the purchase price consists of
      securities and the sale of such securities to the Shareholders would
      require either a registration under any securities laws or the preparation
      of a disclosure document, then, at the option of Warburg, the Shareholders
      may receive, in lieu of such securities, the fair market value of such
      securities in cash, as determined in good faith by the Board.

      (f) Repurchase of Management Shareholder Shares.

               (i) In the event that the employment of any Management Investor
      with the Corporation or any of its Subsidiaries is terminated by the
      Corporation for Just Cause (as defined in the Employment Agreement between
      the Corporation and such Management Investor), the Corporation may, at its
      option, exercisable by delivering written notice to such Management
      Investor at any time specifying the date of the repurchase, repurchase
      from such Management Investor any and all shares of Common Stock owned by
      such Management Investor, and such Management 


                                      -28-
<PAGE>

      Investor shall sell to the Corporation such Common Stock, at a purchase
      price equal to U.S. $1.00 per share of Common Stock.

              (ii) In the event that (A) the employment of any Management
      Investor with the Corporation or any of its Subsidiaries is terminated by
      the Corporation without Just Cause or by the Management Investor for Good
      Reason (as defined in such person's Employment Agreement) or (B) any
      Management Investor voluntarily terminates employment with the Corporation
      or any of its Subsidiaries or (C) the employment of any Management
      Investor is terminated by reason of death, disability, or retirement on or
      after the normal retirement age set forth in the Corporation's (or any
      Subsidiary's) policies, the Corporation may, at its option, exercisable by
      delivering written notice to such Management Investor (or his estate) at
      any time specifying the date of the repurchase, repurchase from such
      Management Investor (or his estate) any and all shares of Common Stock
      owned by such Management Investor, and such Management Investor shall sell
      to the Corporation such Common Stock, at a purchase price per share equal
      to the greater of U.S. $1.00 or the fair market value of such shares of
      Common Stock, as determined in good faith by the Board.

             (iii) Any repurchase pursuant to clauses (i) or (ii) above by the
      Corporation shall be effected by such Management Investor delivering to
      the Corporation the duly endorsed stock certificates evidencing the Common
      Stock to be repurchased, or such other instrument for the transfer of
      ownership thereof as provided by Brazilian law against delivery by the
      Corporation to such Management Investor of the aggregate purchase price
      for such shares of Common Stock.

      (g) Preemptive Right. If at any time after the date hereof, the
Corporation proposes to issue equity securities of any kind (the term "equity
securities" shall include for these purposes any subscription rights, options or
other rights to acquire equity securities and debt securities convertible into
equity securities) of the Corporation, other than the issuance of (i) securities
to the public in a firm commitment underwriting pursuant to a registration
statement filed under any securities laws, (ii) securities pursuant to the
acquisition of another corporation by the Corporation by merger, purchase of
substantially all of the assets or other form of reorganization, (iii) Common
Stock (or options or subscription rights to acquire Common Stock) issued to
Management Investors or pursuant to an employee stock option plan, stock bonus
plan, stock purchase plan or other management equity program approved by the
Shareholders, provided such securities do not exceed seven and one-half percent
(7.5%) of the shares of Common Stock outstanding on the date hereof on a fully
diluted basis after giving effect to the subscription rights held by PageNet,
Multiponto and TVA, with 


                                      -29-
<PAGE>

respect to which the Shareholders hereby agree to waive their preemptive rights,

then as to each Shareholder, the Corporation shall:

      (A) give written notice setting forth in reasonable detail (1) the
designation and all of the terms and provisions of the securities proposed to be
issued (the "Proposed Securities"), including, where applicable, the voting
powers, preferences and relative participating, optional or other special
rights, and the qualification, limitations or restrictions thereof and interest
rate and maturity; (2) the price and other terms of the proposed sale of such
securities; (3) the amount of such securities proposed to be issued; and (4)
such other information as the Shareholders may reasonably request in order to
evaluate the proposed issuance;

      (B) offer to issue to each such Shareholder a portion of the Proposed
Securities equal to a percentage determined by dividing (x) the number of shares
of Common Stock held directly or indirectly by such Shareholder and issuable to
such Shareholder, assuming conversion in full of any convertible securities then
held directly or indirectly by such Shareholder, by (y) the total number of
shares of Common Stock then held directly or indirectly by all of the
Shareholders; and

      (C) offer to issue to each such Shareholder holding Preferred Stock that
portion of the Proposed Securities necessary to preserve such Preferred
Shareholder's ownership interest of the Corporation represented by such
Preferred Stock.

      Each Shareholder holding Preferred Stock hereby agrees to waive its
preemptive rights under Brazilian law except those preemptive rights under (C)
above to purchase the Proposed Securities.

      Each Investor must exercise its purchase rights hereunder within ten (10)
days after receipt of such notice from the Corporation. Each Management Investor
must notify the Corporation within ten (10) days after receipt of such notice of
his election to exercise his purchase rights within thirty (30) days after
receipt of such notice, subject only to the procurement of adequate financing.
If all of the Proposed Securities offered to such Shareholders are not fully
subscribed by such Shareholders, the remaining Proposed Securities will be
reoffered to the Shareholders purchasing their full allotment upon the terms set
forth in this Clause 8(g), until all such Proposed Securities are fully
subscribed for or until all such Shareholders have subscribed for all such
Proposed Securities which they desire to purchase, except that such Shareholders
must exercise their purchase rights within five days after receipt of an such
reoffers. To the extent that the Corporation offers two or more securities in
units, Shareholders must purchase such 


                                      -30-
<PAGE>

units as a whole and will not be given the opportunity to purchase only one of
the securities making up such unit.

      Upon the expiration of the offering periods described above, the
Corporation will be free to sell such Proposed Securities that the Shareholders
have not elected to purchase during the ninety (90) days following such
expiration on terms and conditions no more favorable to the purchasers thereof
than those offered to such holders. Any Proposed Securities offered but not sold
by the Corporation after such 90-day period must be reoffered to the
Shareholders pursuant to this Clause 8(g).

      The election by a Shareholder not to exercise its subscription rights
under this Clause 8(g) in any one instance shall not affect its right (other
than in respect of a reduction in its percentage holdings) as to any subsequent
proposed issuance. Any sale of such securities by the Corporation without first
giving the Shareholders the rights described in this Clause 8(g) shall be void
and of no force and effect.

                       CLAUSE 9--NONCOMPETITION PROVISIONS

      (a) Non-Competition Agreement. Each Investor acknowledges that the
agreements and covenants contained in this Agreement are essential to protect
the value of the Corporation's business and assets and, in its capacity as a
Shareholder, it has obtained and will obtain such confidential or proprietary
knowledge, contacts, know-how and experience and there is a substantial
probability that such knowledge, know-how, contacts and experience could be used
to the substantial advantage of a competitor of the Corporation and to the
Corporation's substantial detriment. Therefore, each Investor other than TVA and
Multiponto agrees that for the period commencing on the date of this Agreement
and ending on the earlier of (i) three years following the date on which such
Investor no longer holds any Common Stock and (ii) the date on which this
Agreement is terminated pursuant to Clause 12(d)(i) (such period is hereinafter
referred to as the "Restricted Period"), neither the Investor nor its controlled
Affiliates shall participate or engage, directly or indirectly, for itself or on
behalf of or in conjunction with any person, partnership, corporation or other
entity, whether as an agent, employee, officer, director, shareholder, partner,
joint venturer, investor or otherwise, in the provision of facilities-based
one-way or two-way paging or portable wireless messaging services (including
without limitation a service that provides substantially the same service as
VoiceNow(R) and other advanced paging services) in Brazil at any time during the
Restricted Period. Notwithstanding the foregoing, nothing herein shall prohibit
an Investor from owning up to 5% of any publicly traded entity. In the event
that TVA engages in any activity that would be prohibited by the provisions of
the second sentence of this Clause 9(a) if it were applicable to TVA, TVA agrees
that, notwithstanding any provisions of this Agreement or the Securities
Subscription Agreement or the bylaws of the 


                                      -31-
<PAGE>

Corporation or otherwise, it shall no longer be entitled to receive from the
Corporation any information not in the public domain or generally known in the
industry. In the event that Multiponto engages in any activity that would be
prohibited by the provisions of the second sentence of this Clause 9(a) if it
were applicable to Multiponto, Multiponto agrees that, notwithstanding any
provisions of this Agreement or the Securities Subscription Agreement or the
bylaws of the Corporation or otherwise, it shall no longer be entitled to
receive from the Corporation any information not in the public domain or
generally known in the industry.

      (b) Nondisclosure of Confidential Information. The Shareholder shall not
disclose to any person or entity or use, either during the Restricted Period or
at any time thereafter, any information not in the public domain or generally
known in the industry, in any form, acquired by the Shareholder or, if acquired
following the Restricted Period, such information which, to the Shareholder's
knowledge, has been acquired, directly or indirectly, from any person or entity
owing a duty of confidentiality to the Corporation or any of its Subsidiaries or
affiliates, relating to the Corporation, its Subsidiaries or affiliates,
including but not limited to information regarding customers, vendors,
suppliers, trade secrets, training programs, manuals or materials, technical
information, contracts, systems, procedures, mailing lists, know-how, trade
names, improvements, price lists, financial or other data (including the
revenues, costs or profits associated with any of the Corporation's products or
services), business plans, code books, invoices and other financial statements,
computer programs, software systems, databases, discs and printouts, plans
(business, technical or otherwise), customer and industry lists, correspondence,
internal reports, personnel files, sales and advertising material, which is or
was used in the business of the Corporation or any of its Subsidiaries. The
Shareholder agrees and acknowledges that all of such information, in any form,
and copies and extracts thereof, are and shall remain the sole and exclusive
property of the Corporation, and upon request of the Board, the Shareholder
shall return to the Corporation the originals and all copies of any such
information provided to or acquired by the Shareholder, and shall have destroyed
or return to the Corporation all files, correspondence and/or other
communications received from the Corporation, maintained and/or originated by
the Shareholder during the Restricted Period. Notwithstanding the foregoing, if
and to the extent that any Investor is a limited partnership, or resells or
transfers the Securities acquired by it to a limited partnership of which such
Investor (or another entity controlled by or under common control with such
Investor) is the majority or controlling general partner or to any other entity
controlled by or under common control with such Investor, financial and other
information regarding the Corporation of the type customarily included in a
private placement memorandum offering interests in a private equity investment
fund may be included in the private placement memorandum or other offering
document used by such 


                                      -32-
<PAGE>

limited partnership in connection with the offering and sale of its interests.
In addition, financial and other information regarding the Corporation of the
type typically provided to limited partners in private equity investment funds
with respect to the investments made by those funds may be provided on a
periodic basis to the limited partners of such limited partnership, and to the
shareholders of the general partner of such limited partnership, provided that
under no circumstances will any proprietary information (which, for this
purpose, excludes such financial information) of the Corporation be disclosed to
such limited partners or shareholders.

      (c) Injunctive Relief; Modification of Provisions. Without intending to
limit the remedies available to the Corporation, each Shareholder acknowledges
that a breach of any of the covenants contained in this Clause 9 may result in
material irreparable injury to the Corporation or its Subsidiaries or Affiliates
for which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of such a
breach or threat thereof, the Corporation shall be entitled to obtain a
temporary restraining order and/or a preliminary or permanent injunction
restraining the Shareholder from engaging in activities prohibited by this
Clause 9 or such other relief as may be required specifically to enforce any of
the covenants in this Clause 9. If any provision of this Clause 9 is determined
by a court of competent jurisdiction to be invalid in part, it shall be
curtailed, both as to time and location, to the minimum extent required for its
validity under the applicable law and shall be binding and enforceable with
respect to each Shareholder as so curtailed. In any case, whether or not the
injunctive relief provided for herein is obtained, the breach of any of the
covenants contained in this Clause 9 shall give rise to the payment by the
violating shareholder to the Corporation, of a penalty equal to the market value
of the Securities held by such Shareholder.

                   CLAUSE 10--INTERPRETATION OF THIS AGREEMENT

      (a)   Terms  Defined.  As used in this  Agreement,  the following  terms
have the respective meaning set forth below:

      Affiliate: means, with respect to any Person, any other Person directly or
indirectly controlling (including, but not limited to, all directors and

constitute a part thereof.

      (f) Monetary Damages, Specific Performance and Injunctive Relief. The
obligations arising from this Agreement shall be registered in the Book of
Registration of Nominative Shares of the Corporation and in the respective share
certificates, if issued, such registration constituting an impediment to the
carrying out of any acts contrary to the provisions of this Agreement, the
Corporation being thus legitimately authorized not to effect, in this case, the
registration of such acts and thus refuse to transfer the ownership or title to
any rights on the shares covered by this Agreement. The failure to comply with
the obligations arising from this Agreement by the Shareholders, their heirs,
successors or assigns, shall give rise to a right of specific performance of
such obligation ("obrigacao de fazer"), the Court order substituting for the
consent of the defaulting party or Shareholders, as provided for in Articles 639
and 641 of the Brazilian Civil Procedure Code, as well as in Article 119 of Law
6.404, of December 15, 1976, notwithstanding the right to receive
indemnification for the losses and damages arising from such violation.

      (g) Consent of the Corporation. For purposes of article 118 of Law 6.404,
of December 15, 1976, one of the counterparts of this Agreement shall be filed
at the Corporation's head offices. The Corporation executes this Agreement as a
consenting party and undertakes to faithfully observe all of the terms and
conditions hereof.

                           CLAUSE 11--INDEMNIFICATION

      The Corporation shall indemnify to the fullest extent permitted under and
in accordance with the laws of Brazil any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative by
reason of the fact that he is or was a director, 


                                      -36-
<PAGE>

officer, employee or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, trustee, employee or agent of
or in any other capacity with another corporation, partnership, joint venture,
trust or other enterprise, against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.

      Expenses incurred in defending a civil or criminal action, suit or
proceeding shall (in the case of any action, suit or proceeding against a
director or officer of the Corporation) or may (in the case of any action, suit
or proceeding against a trustee, employee or agent) be paid by the Corporation
in advance of the final disposition of such action, suit or proceeding as
authorized by the Board upon receipt of an undertaking by or on behalf of the
indemnified person to repay such amount if it shall ultimately be determined
that he is not entitled to be indemnified by the Corporation as authorized in
this Clause.

      No director shall be personally liable to the Corporation or any
Shareholder for monetary damages for breach of fiduciary duty as a director,
except for any matter in respect of which such director shall be liable by
reason that, in addition to any and all other requirements for liability, he:

               (i)   shall   have   breached   his  duty  of  loyalty  to  the
      Corporation or the Shareholder(s);

              (ii)   shall not have  acted in good  faith or,  in  failing  to
      act, shall not have acted in good faith;

             (iii) shall have acted in a manner involving intentional misconduct
      or a knowing violation of law or, in failing to act, shall have acted in a
      manner involving intentional misconduct or a knowing violation of law; or

              (iv)   shall have derived an improper personal benefit.

      The indemnification and other rights set forth in this Article shall not
be exclusive of any provisions with respect thereto in the By-laws or any other
contract or agreement between the Corporation and any officer, director,
employee or agent of the Corporation.

                            CLAUSE 12--MISCELLANEOUS

the Corporation or one of its Affiliates to become a shareholder (to the largest
degree permitted under applicable law) in such entities or such other entity as
may be the transferee of the Licenses.

      (c) Shareholder Commitment to Vote. Each of the Shareholders agrees that,

of this Agreement.

      (d) Termination. The initial term of this Agreement shall commence on the
date hereof and shall continue until the tenth (10th) anniversary of the date

directly or indirectly by more than one of the Shareholders and (ii) no
Shareholder has given notice of termination of this Agreement by delivering

            (A) Each of Multiponto, San Francisco and TVA covenants to cause the
      following provisions to be completed within six (6) months of the Closing
      Date (as defined in the Securities Subscription Agreement):

            (i)   use its best efforts to obtain all necessary approvals and to
                  comply with all applicable regulations and each shall
                  incorporate a wholly owned new company ("NewCo") for the sole
                  purpose of holding the Paging Assets; and

            (ii)  use its best efforts to obtain all necessary approvals and to
                  comply with all applicable regulations and each shall make the
                  necessary applications to the Ministry of Communications of
                  Brazil in order to transfer the Paging Assets to NewCo; and

            (iii) assuming such approvals are obtained, transfer the Paging
                  Assets to NewCo in a lawful manner; and

            (iv)  assuming such approvals are obtained, each shall permit the
                  Corporation to purchase 49% of the voting stock and 100% of
                  the non-voting stock, which shall constitute 66 2/3% of all of
                  the capital stock, of each NewCo, the consideration being the
                  receipt by each of Multiponto and TVA of Subscription Bonds
                  pursuant to the Securities Subscription Agreement and, in the
                  case of San Francisco, by an indirect participation of its
                  principal quotaholder, through IPC, in the Corporation; and

            (v)   assuming such approvals are obtained, use its best efforts to
                  obtain all necessary approvals in order to transfer to the
                  Corporation the Licenses


                                      -41-
<PAGE>

                   and the remaining voting stock of NewCo, and all its Paging
                   Assets; and

            (vi)  each shall use its best efforts, in cooperation with the
                  Company, to obtain assurances from the Ministry of
                  Communications so as to permit the organization of the
                  business using a reseller structure which employs two-party
                  subscriber agreements between the Operator or its agents and
                  the subscribers to the paging services; and each shall take
                  all measures necessary to amend the operating agreement
                  between each and the Company so as to achieve this objective
                  once such assurances have been obtained.

      (B) In connection with the foregoing provisions of Section 12(m)(A), the
Corporation agrees to reimburse each of Multiponto, San Francisco and TVA for
their reasonable out-of-pocket expenses incurred in connection with the
foregoing activities, up to a maximum of $10,000 per entity.

      (C) In the event of a breach of Section 12(m)(A), the breaching party
shall forfeit its equity interest in the Corporation; provided that the breach
was not the result of the action or inaction of a government or regulatory
authority, such as the Ministry of Communications of Brazil. In the case of a
breach by San Francisco (which does not have an equity interest in the
Corporation), IPC shall forfeit 2,000 of its 8,000 shares of Common Stock and
25% (up to a maximum of 2,000 shares) of its shares of Preferred Stock, but
shall retain the balance of its equity interest in the Corporation.

      (D) The Shareholders covenant and agree that they shall organize or
restructure the Corporation in order to comply with Brazilian legal and
regulatory requirements relating to foreign ownership of the Paging Assets.

      (E) IPC shall transfer its equity interest in the Corporation (or its
remaining interest in each Paging Assets holding company) to a Brazilian entity
if necessary in order to satisfy Brazilian ownership requirements under
Brazilian law.

      (F) The Corporation and the shareholders of the respective Paging Assets
companies will agree to enter into shareholder agreements pursuant to which the
Corporation shall have a veto over any transfer or any other disposition of the
Paging Assets or use of them not related to the conduct of the Corporation's
business.

repurchase from such Investor, and such Investor shall sell to the Company, that
number of shares of Common Stock equal to the excess of (i) the number of shares
of Initial Common Stock owned by such Investor, over (ii) the number of shares
of Preferred Stock owned by such Investor, with the effect that such Investor

Stock.

1.3.     Subsequent Issuances of Preferred Stock

            (a) Subject to the terms and conditions hereof, from time to time
after the Closing Date at the written request of the Board of Directors of the

Date.

            (c) The obligation of the Initial Stock Investors to subscribe and

1.4.     Subscription Bonds

            Subject to the terms and conditions hereof, on the Closing Date the
Company shall issue the Subscription Bonds to each of the Investors named on
Schedule 2.1 to purchase the number of shares of Common Stock set forth opposite
their respective names on Schedule 2.1 in accordance with Section 2 below.

1.5.     Several Obligations

            The obligations of the Investors hereunder are several and not
joint, and no Investor shall be obligated to subscribe for and purchase any
Securities hereunder unless each of the other Investors has subscribed for and
purchased the Securities it is obligated to purchase hereunder.

SECTION 2.  SUBSCRIPTION BONDS

2.1.     Issuance of Subscription Bonds

            The Company hereby agrees to issue to each of the persons named on
Schedule 2.1 (each a "Holder"), a subscription bond (a "Subscription Bond"),
exercisable for an aggregate of 9,996 shares of the Common Stock of the Company
at a purchase price, subject to the provisions of Section 2.4 hereof, of U.S.
$1.00 per share (the "Purchase Price"). The Purchase Price and the number and
character of such shares of Common Stock are subject to adjustment as provided
below.

2.2.     Exercise of Subscription Bond

            The purchase rights evidenced by each Subscription Bond shall be
exercised by the Holder surrendering such Subscription Bond, with the form of
subscription at the end hereof duly executed by such Holder, to the Company at
its office, accompanied by payment, in cash, by certified or official bank check
or by wire transfer of an amount equal to the Purchase Price multiplied by the
number of shares of Common Stock being purchased pursuant to such exercise of
the Subscription Bond on or before the fifth anniversary of the date of such
Subscription Bond.

            2.2.1.  Partial Exercise

            Each Subscription Bond may be exercised for less than the full
number of shares of Common Stock, in which case the number of shares receivable
upon the exercise of such Subscription Bond as a whole, and the sum payable upon
the exercise of such Subscription Bond as a whole, shall be proportionately
reduced. Upon any such partial exercise, the Company at its expense will
forthwith issue to the Holder a new Subscription Bond or Subscription Bonds of
like tenor calling for the number of shares of Common Stock as to which rights
have not 


                                      -4-
<PAGE>

been exercised, such Subscription Bond or Subscription Bonds to be issued in the
name of the Holder or his nominee (upon payment by such Holder of any applicable
transfer taxes).

2.3.     Registration of Stock on Exercise

            Immediately after the exercise of a Subscription Bond and payment of
the Purchase Price, the Company, at its expense, will cause to be registered in
the Company's book of registration of shares the number of fully paid and
non-assessable shares of Common Stock or other securities or property to which
such Holder shall be entitled upon such exercise. The Company agrees that the
shares of Common Stock so registered shall be deemed to be issued to the Holder
as the record owner of such shares as of the close of business on the date on
which the corresponding Subscription Bond shall have been surrendered and
payment made for such shares as aforesaid.

2.4.     Adjustments

            The Purchase Price shall be subject to adjustment from time to time
in accordance with this Section 2.4. Upon each adjustment of the Purchase Price
pursuant to this Section 2.4, the Holder shall thereafter be entitled to acquire
upon exercise, at the Purchase Price resulting from such adjustment, the number
of shares of the Common Stock obtainable by multiplying the Purchase Price in
effect immediately prior to such adjustment by the number of shares of the
Common Stock acquirable immediately prior to such adjustment and dividing the
product thereof by the Purchase Price resulting from such adjustment.

            2.4.1.  Adjustment for Stock Dividends

            (a) If and whenever on or after the date of issuance hereof the
Company shall declare a dividend or make any other distribution upon the capital
stock of the Company payable in Common Stock, any rights to subscribe for or to
purchase, or any options or subscription bonds for the purchase of, Common Stock
or any stock of other securities convertible or exchangeable for Common Stock,
if such rights, options or subscription bonds permit the holder thereof to
acquire the Common Stock at a price that is below fair market value (such
rights, options or subscription bonds being herein called "Options" and such
convertible or exchangeable stock or securities being herein called "Convertible
Securities"), then forthwith upon such declaration of a dividend or other
distribution (the "Triggering Transaction"), the Purchase Price shall be reduced
to the Purchase Price (calculated to the nearest tenth of a cent) determined by
dividing:

                  (i) an amount equal to the product derived by multiplying the
Number of Shares of Common Stock Deemed Outstanding immediately prior to the
Triggering Transaction by the Purchase Price then in effect, by


                                      -5-
<PAGE>

                  (ii) an amount equal to the sum of (x) the Number of Shares of
Common Stock Deemed Outstanding immediately prior to such Triggering Transaction
plus (y) the number of shares of Common Stock issued (or issuable if all of such
Options or Convertible Securities are exercised or converted as the case may be)
in connection with the Triggering Transaction.

            The term "Number of Shares of Common Stock Deemed Outstanding" at
any given time shall mean the sum of (i) the number of shares of the Common
Stock outstanding at such time, and (ii) the total maximum amount of Common
Stock issuable upon the exercise of Options or the conversion or exchange of
Convertible Securities.

            For purposes of determining the adjusted Purchase Price under this
Section 2.4.1, Options or Convertible Securities issuable in payment of such
dividend or distribution shall be deemed to have been issued or sold without
consideration.

            (b) In case the Company shall at any time subdivide (other than by
means of a dividend payable in Common Stock covered by this Section 2.4.1), its
outstanding shares of Common Stock into a greater number of shares, the Purchase
Price in effect immediately prior to such subdivision shall be proportionately
reduced, and, conversely, in case the outstanding shares of Common Stock of the
Company shall be combined into a smaller number of shares, the Purchase Price in
effect immediately prior to such combination shall be proportionately increased.

            2.4.2.     Reorganization, Reclassification, Consolidation,
                       Merger or Sale of Assets

            If any capital reorganization or reclassification of the capital
stock of the Company, or consolidation or merger of the Company with another
corporation, or the sale of all or substantially all of its assets to another
corporation shall be effected in such a way that holders of Common Stock shall
be entitled to receive stock, securities, cash or other property with respect to
or in exchange for Common Stock, then, as a condition of such reorganization,
reclassification, consolidation, merger or sale, lawful and adequate provision
shall be made whereby the Holder shall have the right to acquire and receive
upon exercise of a Subscription Bond such shares of stock, securities, cash or
other property issuable or payable (as part of the reorganization,
reclassification, consolidation, merger or sale) with respect to or in exchange
for such number of outstanding shares of the Company's Common Stock as would
have been received upon exercise of such Subscription Bond at the Purchase Price
then in effect. The Company will not effect any such consolidation, merger or
sale, unless prior to the consummation thereof the successor corporation (if
other than the Company) resulting from such consolidation or merger or the
corporation purchasing such assets shall assume by written 


                                      -6-
<PAGE>

instrument mailed or delivered to the Holder at the last address of such Holder
appearing on the books of the Company, the obligation to deliver to such Holder
such shares of stock, securities or assets as, in accordance with the foregoing
provisions, such Holder may be entitled to purchase.

            2.4.3.  Notices of Record Date, Etc.

            In the event that

            (1) the Company shall declare any cash dividend upon its Common
Stock, or

            (2) the Company shall declare any dividend upon its Common Stock
payable in stock or make any special dividend or other distribution to the
holders of its Common Stock, or

            (3) the Company shall offer for subscription pro rata to the holders
of its Common Stock any additional shares of stock of any class or other rights,
or

            (4) there shall be any capital reorganization or reclassification of
the capital stock of the Company, including any subdivision or combination of
its outstanding shares of Common Stock, or consolidation or merger of the
Company with, or sale of all or substantially all of its assets to, another
corporation, or

            (5) there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then, in connection with such event, the Company shall give to the Holder:

                  (i) at least twenty (20) days' prior written notice of the
date on which the books of the Company shall close or a record shall be taken
for such dividend, distribution or subscription rights or for determining rights
to vote in respect of any such reorganization, reclassification, consolidation,
merger, sale, dissolution, liquidation or winding up; and

                  (ii) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding up, at least
twenty (20) days' prior written notice of the date when the same shall take
place.

            Such notice in accordance with the foregoing clause (i) shall also
specify, in the case of any such dividend, distribution or subscription rights,
the date on which the holders of Common Stock shall be entitled thereto, and
such notice in accordance with the foregoing clause (ii) shall also specify the
date on which the holders of Common Stock shall be entitled to exchange their
Common Stock for securities or other property deliverable upon such
reorganization, reclassification, 


                                      -7-
<PAGE>

consolidation, merger, sale, dissolution, liquidation or winding up, as the case
may be. Each such written notice shall be given by first class mail, postage
prepaid, addressed to the Holder at the address of such Holder as shown on the
books of the Company.

            2.4.4.  Adjustment by Shareholders

            If any event occurs as to which, in the opinion of the holders of a
majority of the outstanding Preferred Stock, the provisions of this Section 2.4
are not strictly applicable or if strictly applicable would not fairly protect
the rights of the Holder in accordance with the essential intent and principles
of such provisions, then the Company shall make an adjustment in the application
of such provisions, in accordance with such essential intent and principles, so
as to protect such rights as aforesaid, but in no event shall any adjustment
have the effect of increasing the Purchase Price as otherwise determined
pursuant to any of the provisions of this Section 2.4 except in the case of a
combination of shares of a type contemplated in Section 2.4.1 and then in no
event to an amount larger than the Purchase Price as adjusted pursuant to this
Section 2.4.

            2.4.5.  Officer's Statement as to Adjustments

            Whenever the Purchase Price shall be adjusted as provided in Section
2.4 hereof, the Company shall forthwith file at each office designated for the
exercise of this Subscription Bond, a statement, signed by the Chairman of the
Board, the President, any Vice President or Treasurer of the Company, showing in
reasonable detail the facts requiring such adjustment and the Purchase Price
that will be effective after such adjustment. The Company shall also cause a
notice setting forth any such adjustments to be sent by mail, first class,
postage prepaid, to the record Holder at his or its address appearing on the
Company's book of registration of shares. If such notice relates to an
adjustment resulting from an event referred to in Section 2.4.3, such notice
shall be included as part of the notice required to be mailed and published
under the provisions of Section 2.4.3 hereof.

2.5.     No Impairment

            The Company will not, by amendment of its by-laws or through
reorganization, consolidation, merger, dissolution, sale of assets or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of any Subscription Bond, but will at all times in good faith assist
in the carrying out of all such terms and in the taking of all such action as
may be necessary or appropriate in order to protect the rights of the Holder
against impairment. Without limiting the generality of the foregoing, the
Company will not increase the par value of any shares of stock receivable upon
the exercise of each Subscription Bond above the amount payable therefor upon
such exercise, and at all times will take all such action as may 


                                      -8-
<PAGE>

be necessary or appropriate in order that the Company may validly and legally
issue fully paid and non-assessable stock upon the exercise of each Subscription
Bond.

2.6.     Reservation of Stock, etc., issuable on exercise of Subscription
         Bonds

            The Company shall at all times reserve and keep available out of its
authorized but unissued stock, solely for the issuance and delivery upon the
exercise of each Subscription Bond and other similar Subscription Bonds, such
number of its duly authorized shares of Common Stock as from time to time shall
be issuable upon the exercise of each Subscription Bond and all other similar
warrants at the time outstanding.

2.7.     Replacement of Subscription Bond

            Upon receipt of evidence reasonably satisfactory to the Company of
the loss, theft, destruction or mutilation of a Subscription Bond and (in the
case of loss, theft or destruction) upon delivery of an indemnity agreement
(with surety if reasonably required) in an amount reasonably satisfactory to it,
or (in the case of mutilation) upon surrender and cancellation thereof, the
Company will issue, in lieu thereof, a new Subscription Bond of like tenor.

2.8.     Remedies

            The Company stipulates that the remedies at law of the Holder in the
event of any default by the Company in the performance of or compliance with any
of the terms of a Subscription Bond are not and will not be adequate, and that
the same may be specifically enforced.

2.9.     Negotiability, etc.

            Each Subscription Bond is issued upon the following terms, to all of
which each taker or owner thereof consents and agrees:

            (a) Subject to the legend appearing in Section 2.11 hereof, title to
a Subscription Bond may be transferred by endorsement (by the Holder executing a
form of assignment including guaranty of signature) and delivery in the same
manner as in the case of a negotiable instrument transferable by endorsement and
delivery.

            (b) Any person in possession of a Subscription Bond properly
endorsed is authorized to represent himself as absolute owner thereof and is
granted power to transfer absolute title thereto by endorsement and delivery
thereof to a bona fide purchaser thereof for value; each prior taker or owner 
waives and renounces all of his equities or rights in a Subscription Bond in 
favor of every such bona fide purchaser, and every such bona fide 


                                       -9-
<PAGE>

purchaser shall acquire title thereto and to all rights represented hereby and
thereby.

            (c) Until a Subscription Bond is transferred on the books of the
Company, the Company may treat the registered Holder as the absolute owner
thereof for all purposes without being affected by any notice to the contrary.

            (d) Prior to the exercise of a Subscription Bond, the Holder shall
not be entitled to any rights of a stockholder of the Company with respect to
shares for which the Subscription Bond shall be exercisable, including, without
limitation, the right to vote, to receive dividends or other distributions or to
exercise any preemptive rights, and shall not be entitled to receive any notice
of any proceedings of the Company, except as provided herein.

            (e) The Company shall not be required to pay any federal or state
transfer tax or charge in Brazil or the United States that may be payable in
respect of any transfer involved in the transfer or delivery of a Subscription
Bond or the entry in the book of registration of shares of Common Stock or the
entry in the book of transfer of shares of Common Stock upon the exercise of a
Subscription Bond until any and all such taxes and charges shall have been paid
by the Holder or until it has been established to the Company's satisfaction
that no such tax or charge is due.

2.10.    Subdivision of Bonds

            Each Subscription Bond (as well as any new Subscription Bonds issued
pursuant to the provisions of this Section) is exchangeable, upon the surrender
thereof by the Holder, at the principal office of the Company, for any number of
new Subscription Bonds of like tenor and date representing in the aggregate the
right to subscribe for and purchase the number of shares of Common Stock of the
Company which may be subscribed for and purchased hereunder.

2.11.    Legends

            All Subscription Bonds shall be in substantially the form as Exhibit
A attached hereto and shall bear the following legends:

      1.2. Requested Registration

      (a) Request for Registration. (i) If the Company shall receive from an
Initiating Holder a written request that the Company effect any registration
with respect to all or a part of the Registrable Securities, the Company will:

            (A) promptly give written notice of the proposed registration,
      qualification or compliance to all other Holders of Registrable
      Securities; and

            (B) as soon as practicable, use its diligent best efforts to effect
      such registration in the jurisdictions of Brazil or the United States or
      any other jurisdiction which may be accessed by the Company (including,
      without limitation, the execution of an undertaking to file post-effective
      amendments, appropriate qualification under applicable Securities Laws and
      appropriate compliance with applicable regulations issued under the
      Securities Act) as may be so requested and as would permit or facilitate
      the sale and distribution of all or such portion of such Registrable
      Securities as are specified in such request, together with all or such
      portion of the Registrable Securities of any Holder or Holders joining in
      such request as are specified in a written request received by the Company
      within ten (10) business days after written notice from the Company is
      given under Section 1.2(a)(A); provided that the Company shall not be
      obligated to effect, or take any action to effect, any such registration
      pursuant to this Section 1.2(a):

            (x) In any particular jurisdiction in which the Company would be
      required to execute a general consent to service of process in effecting
      such registration, qualification or compliance, unless the Company is
      already subject to service in such jurisdiction and except as may be
      required by the Securities Laws;

            (y) After the Company has effected two (2) such registrations
      pursuant to this Section 1.2 and such registrations have been declared or
      ordered effective and the sales of such Registrable Securities shall have
      closed; or

            (z) If the Registrable Securities requested by all Holders to be
      registered pursuant to such request do not have an anticipated aggregate
      public offering price (before any underwriting discounts and commissions)
      of not less than $15,000,000 (or $30,000,000 if such requested
      registration is the initial public offering).

            The  registration  statement  filed  pursuant to the request of an
Initiating  Holder may,  subject to the  provisions  of Section  1.2(b) below,
include  other  securities  of the Company  


                                       3
<PAGE>

which are held by Persons who, by virtue of agreements with the Company, are
entitled to include their securities in any such registration ("Other Holders"),
subject to the terms of this Agreement.

      The registration rights set forth in this Section 1 shall be assignable,
in whole or in part, to any transferee of Registrable Securities (who shall be
bound by all obligations of this Section 1).

      (b) Underwriting. If an Initiating Holder intends to distribute the
Registrable Securities covered by its request by means of an underwriting, it
shall so advise the Company as a part of its request made pursuant to Section
1.2.

      If Other Holders request such inclusion, the Holders shall offer to
include the Registrable Securities of such Other Holders in the underwriting and
may condition such offer on their acceptance of the further applicable
provisions of this Section 1. The Holders whose Registrable Securities are to be
included in such registration and the Company shall (together with Other Holders
proposing to distribute their Registrable Securities through such underwriting)
enter into an underwriting agreement in customary form with the representative
of the underwriter or underwriters selected for such underwriting by the
Initiating Holder and reasonably acceptable to the Company. Notwithstanding any
other provision of this Section 1.2, if the representative advises the Holders
in writing that marketing factors require a limitation on the number of shares
of Registrable Securities to be underwritten, the securities of the Company held
by Other Holders shall be excluded from such registration to the extent so
required by such limitation. If, after the exclusion of such shares of
Registrable Securities, further reductions are still required, the number of
shares of Registrable Securities included in the registration by each Holder
shall be reduced on a pro rata basis (based on the number of shares of
Registrable Securities held by such Holder), by such minimum number of shares of
Registrable Securities as is necessary to comply with such request. No
Registrable Securities excluded from the underwriting by reason of the
underwriter's marketing limitation shall be included in such registration. In
addition to the foregoing limitation, if the registration proposed to be
underwritten by the Company relates to Common Stock, but not Preferred Stock (or
vice versa), the registration can, at the election of the Company, be limited to
the type of Registrable Securities proposed to be registered. If any Other
Holder who has requested inclusion in such registration as provided above
disapproves of the terms of the underwriting, such person may elect to withdraw
therefrom by written notice to the Company, the underwriter and the Initiating
Holder. The Registrable Securities so withdrawn shall also be withdrawn from
registration. If the underwriter has not limited the number of Registrable
Securities to be underwritten, the Company may include its securities for its
own account in such registration 


                                       4
<PAGE>

if the representative so agrees and if the number of Registrable Securities and
other securities which would otherwise have been included in such registration
and underwriting will not thereby be limited.

      1.3. Company Registration.

      (a) Inclusion in Registration. If the Company shall determine to register
any of its securities either for its own account or for the account of a
security holder or holders exercising their respective demand registration
rights, other than a registration relating solely to employee benefit plans, or
a registration relating solely to a SEC Rule 145 transaction, or a registration
on any registration form which does not permit secondary sales or does not
include substantially the same information as would be required to be included
in a registration statement covering the sale of Registrable Securities, the
Company will:

            (i) promptly give to each of the Holders of Registrable Securities a
      written notice thereof (which shall include a list of the jurisdictions in
      which the Company intends to attempt to qualify such securities under the
      applicable Securities Laws); and

            (ii) include in such registration (and any related qualification
      under the Securities Laws or other compliance), and in any underwriting
      involved therein, all the Registrable Securities specified in a written
      request or requests, made by the Holders within fifteen (15) days after
      receipt of the written notice from the Company described in clause (A)
      above, except as set forth in Section 1.3(b) below. Such written request
      may specify all or a part of the Holders' Registrable Securities.

      (b) Underwriting. If the registration of which the Company gives notice is
for a registered public offering involving an underwriting, the Company shall so
advise each of the Holders as a part of the written notice given pursuant to
Section 1.3(a)(i). In such event, the right of each of the Holders to
registration pursuant to this Section 1.3 shall be conditioned upon such
Holders' participation in such underwriting and the inclusion of such Holders'
Registrable Securities in the underwriting to the extent provided herein. The
Holders whose Registrable Securities are to be included in such registration
shall (together with the Company and the Other Holders distributing their
securities through such underwriting) enter into an underwriting agreement in
customary form with the representative of the underwriter or underwriters
selected for underwriting by the Company. Notwithstanding any other provision of
this Section 1.3, if the representative determines that marketing factors
require a limitation on the number of shares of Registrable Securities to be
underwritten, and (x) if such registration is the initial public offering, the
representative may (subject to the allocation priority set forth below) exclude
from such registration and underwriting some or all of the shares of Registrable
Securities which would otherwise be underwritten pursuant hereto, and (y) if
such registration is other than the initial public offering, the representative


                                       5
<PAGE>

may (subject to the allocation priority set forth below) limit the number of
Registrable Securities to be included in the registration and underwriting to
not less than twenty-five percent (25%) of the Registrable Securities included
therein (based on aggregate market values). The Company shall so advise all
Holders of Registrable Securities requesting registration, and the number of
shares of Registrable Securities that are entitled to be included in the
registration and underwriting shall be allocated in the following manner: The
securities of the Company held by officers, directors and Other Holders of the
Company (other than Registrable Securities and other than securities held by
holders who by contractual right demanded such registration ("Demanding
Holders")) shall be excluded from such registration and underwriting to the
extent required by such limitation, and, if a limitation on the number of shares
is still required, the securities that may be included in the registration and
underwriting by each of the Holders and Demanding Holders shall be reduced, on a
pro rata basis (based on the number of shares held by such Holder), by such
minimum number of shares as is necessary to comply with such limitation. In
addition to the foregoing limitation, if the registration proposed to be
underwritten by the Company relates to Common Stock, but not Preferred Stock (or
vice versa), the registration can, at the election of the Company, be limited to
the type of securities proposed to be registered. If any of the Holders or any
officer, director or Other Holder disapproves of the terms of any such
underwriting, he may elect to withdraw therefrom by written notice to the
Company and the underwriter. Any Registrable Securities or other securities
excluded or withdrawn from such underwriting shall be withdrawn from such
registration.

      1.4. Form S-3

      Following an initial public offering in the United States, the Company
shall use its best efforts to qualify for registration on Form S-3 for secondary
sales. After the Company has qualified for the use of Form S-3 (or, if
available, Form F-3), Holders of Registrable Securities shall have the right to
request up to 4 registrations on Form S-3 (such requests shall be in writing and
shall state the Registrable Securities to be disposed of and the intended method
of disposition of such Registrable Securities by such Holders), subject only to
the following:

      (a) The Company shall not be required to effect a registration pursuant to
this Section 1.4 unless the Holder or Holders of Registrable Securities
requesting registration propose to dispose of Registrable Securities having an
aggregate price to 


                                       6
<PAGE>

the public (before deduction of underwriting discounts and expenses of sale) of
more than $5,000,000.

            (b) The Company shall not be required to effect a registration
      pursuant to this Section 1.4 within one hundred eighty (180) days of the
      effective date of the most recent registration pursuant to this Section 1
      in which securities held by the requesting Holder could have been included
      for sale or distribution.

            (c) The Company shall not be obligated to effect any registration
      pursuant to this Section 1.4 in any particular jurisdiction in which the
      Company would be required to execute a general consent to service of
      process in effecting such registration, qualification or compliance,
      unless the Company is already subject to service in such jurisdiction and
      except as may be required by the Securities Act or applicable rules or
      regulations thereunder.

      The Company shall give written notice to all Holders of such Registrable
Securities of the receipt of a request for registration pursuant to this Section
1.4 and shall provide a reasonable opportunity for other Holders of such
Registrable Securities to participate in the registration, provided that if the
registration is for an underwritten offering, the terms of Section 1.2(b) shall
apply to all participants in such offering. Subject to the foregoing, the
Company will use its best efforts to effect promptly the registration of all
such Registrable Securities on Form S-3 to the extent requested by the Holder or
Holders thereof for purposes of disposition.

      1.5. Expenses of Registration

      All Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to this Section 1 shall be borne by the
Company, and all Selling Expenses shall be borne by the Holders of the
securities so registered pro rata on the basis of the number of their shares so
registered; provided, however, that the Company shall not be required to pay any
Registration Expenses if, as a result of the withdrawal of a request for
registration by any of the Holders, as applicable, the registration statement
does not become effective, in which case each of the Holders and Other Holders
requesting registration shall bear such Registration Expenses pro rata on the
basis of the number of their shares so included in the registration request, and
provided further that such registration shall not be counted as a registration
pursuant to Section 1.2(a) or 1.4.

      1.6. Registration Procedures

      In the case of each registration effected by the Company pursuant to this
Section 1, the Company will keep the Holders, as applicable, advised in writing
as to the initiation 


                                       7
<PAGE>

of each registration and as to the completion thereof. At its expense, the
Company will:

      (a) keep such registration effective for a period of one hundred twenty
(120) days or until the Holders, as applicable, have completed the distribution
described in the registration statement relating thereto, whichever first
occurs; provided, however, that (i) such 120-day period shall be extended for a
period of time equal to the period during which the Holders, as applicable,
refrain from selling any securities in accordance with provisions in Section
1.10 hereof; and (ii) in the case of any registration of Registrable Securities
on Form S-3 which are intended to be offered on a continuous or delayed basis,
such 120-day period shall be extended until all such Registrable Securities are
sold, provided that Rule 415, or any successor rule under the Securities Act,
permits an offering on a continuous or delayed basis, and provided further that
applicable rules under the Securities Act governing the obligation to file a
post-effective amendment permit, in lieu of filing a post-effective amendment
which (y) includes any prospectus required by Section 10(a) of the Securities
Act or (z) reflects facts or events representing a material or fundamental
change in the information set forth in the registration statement, the
incorporation by reference of information required to be included in (y) and (z)
above to be contained in periodic reports filed pursuant to Section 12 or 15(d)
of the Exchange Act in the registration statement; and

      (b) furnish such number of prospectuses and other documents incident
thereto as each of the Holders, as applicable, from time to time may reasonably
request.

      1.7. Indemnification

      (a) The Company will indemnify each of the Holders, as applicable, each of
its officers, directors and partners, and each person controlling each of the
Holders, with respect to each registration which has been effected pursuant to
this Section 1, and each underwriter, if any, and each person who controls any
underwriter, against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any prospectus, offering
circular or other document (including any related registration statement,
notification or the like) incident to any such registration, qualification or
compliance, or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or any violation by the Company of the Securities Laws
applicable to the Company and relating to action or inaction required of the
Company in connection with any such registration, qualification or compliance,
and will reimburse each of the Holders, each of its officers, directors and
partners, and each person controlling each of the Holders, each such underwriter
and each person who 


                                       8
<PAGE>

controls any such underwriter, for any legal and any other expenses reasonably
incurred in connection with investigating and defending any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission based upon written
information furnished to the Company by the Holders or underwriter and stated to
be specifically for use therein.

      (b) Each of the Holders will, if Registrable Securities held by it are
included in the securities as to which such registration, qualification or
compliance is being effected, indemnify the Company, each of its directors and
officers and each underwriter, if any, of the Company's securities covered by
such a registration statement, each person who controls the Company or such
underwriter, each Other Holder and each of their officers, directors, and
partners, and each person controlling such Other Holder against all claims,
losses, damages and liabilities (or actions in respect thereof) arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any such registration statement, prospectus, offering circular
or other document made by such Holder, or any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements by such Holder therein not misleading, and will reimburse the
Company and such Other Holders, directors, officers, partners, persons,
underwriters or control persons for any legal or any other expenses reasonably
incurred in connection with investigating or defending any such claim, loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by such Holder and stated to be specifically for use
therein; provided, however, that the obligations of each of the Holders
hereunder shall be limited to an amount equal to the net proceeds to such Holder
of securities sold as contemplated herein.

      (c) Each party entitled to indemnification under this Section 1.7 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom; provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or any litigation resulting
therefrom, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld) and the Indemnified Party may participate in such
defense at such party's expense (unless the Indemnified Party shall have
reasonably concluded that there may 


                                       9
<PAGE>

be a conflict of interest between the Indemnifying Party and the Indemnified
Party in such action, in which case the fees and expenses of counsel shall be at
the expense of the Indemnifying Party), and provided further that the failure of
any Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 1.7 unless the
Indemnifying Party is materially prejudiced thereby. No Indemnifying Party, in
the defense of any such claim or litigation shall, except with the consent of
each Indemnified Party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect to such claim or litigation. Each Indemnified Party shall
furnish such information regarding itself or the claim in question as an
Indemnifying Party may reasonably request in writing and as shall be reasonably
required in connection with the defense of such claim and litigation resulting
therefrom.

      (d) If the indemnification provided for in this Section 1.7 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage or expense referred to herein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party
hereunder, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, liability, claim, damage or expense in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party on the one hand and of the Indemnified Party on the other in connection
with the statements or omissions which resulted in such loss, liability, claim,
damage or expense, as well as any other relevant equitable considerations. The
relative fault of the Indemnifying Party and of the Indemnified Party shall be
determined by reference to, among other things, whether the untrue (or alleged
untrue) statement of a material fact or the omission (or alleged omission) to
state a material fact relates to information supplied by the Indemnifying Party
or by the Indemnified Party and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.

      (e) Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with any underwritten public offering contemplated by this
Agreement are in conflict with the foregoing provisions, the provisions in such
underwriting agreement shall be controlling.

      (f) The foregoing indemnity agreement of the Company and the Holders is
subject to the condition that, insofar as they relate to any loss, claim,
liability or damage made in a preliminary prospectus but eliminated or remedied

      1.8. Information by the Holders

      Each of the Holders holding securities included in any registration shall
furnish to the Company such information regarding such Holder and the
distribution proposed by such Holder as the Company may reasonably request in
writing and as shall be reasonably required in connection with any registration,
qualification or compliance referred to in this Section 1.

      1.9. Rule 144 Reporting

      With a view to making available the benefits of certain rules and
regulations of the SEC which may permit the sale of restricted securities to the
public without registration, the Company agrees to:

      (a) make and keep public information available as those terms are
understood and defined in Rule 144 under the Securities Act ("Rule 144"), at all
times from and after ninety (90) days following the effective date of the first
registration statement under the Securities Act filed by the Company for an
offering of its securities to the general public;

      (b) use its best efforts to file with the SEC in a timely manner all
reports and other documents required of the Company under the Securities Act and
the Exchange Act at any time after it has become subject to such reporting
requirements; and

      (c) so long as the Holder owns any Registrable Securities, furnish to the
Holder upon request, a written statement by the Company as to its compliance
with the reporting requirements of Rule 144 (at any time from and after ninety
(90) days following the effective date of the first registration statement filed
by the Company for an offering of its securities to the general public), and of
the Securities Act and the Exchange Act (at any time after it has become subject
to such reporting requirements), a copy of the most recent annual or quarterly
report of the Company, and such other reports and documents so filed as the
Holder may reasonably request in availing itself of any rule or regulation of
the SEC allowing the Holder to sell any such securities without registration.

      1.10. "Market Stand-off" Agreement

      Each of the Holders agrees, if requested by the Company and an underwriter
of Registrable Securities (or other securities) of the Company, not to sell or
otherwise transfer or 


                                       11
<PAGE>

dispose of any Registrable Securities (or other securities) of the Company held
by such Holder during the 180-day period following the effective date of a
registration statement of the Company, provided that:

      (a) such agreement only applies to the initial public offering; and

      (b) all officers and directors of the Company enter into similar
agreements.

      If requested by the underwriters, the Holders shall execute a separate
agreement to the foregoing effect. The Company may impose stop-transfer
instructions with respect to the shares (or securities) subject to the foregoing
restriction until the end of said 180-day period. The provisions of this Section
1.10 shall be binding upon any transferee who acquires Registrable Securities,
whether or not such transferee is entitled to the registration rights provided
hereunder.

      1.11. Termination.

      The registration rights set forth in this Section 1 shall not be available
to any Holder if, in the opinion of counsel to the Company, all of the
Registrable Securities then owned by such Holder could be sold in any 90-day
period pursuant to Rule 144 (without giving effect to the provisions of Rule
144(k)).

                                 - - - - - - - - - -

PNB's current facilities and equipment and with the construction, where
necessary, of additional facilities and sites for the provision of
Telecommunications Services by PNB in the Territory, and (b) provide the
services listed on Exhibit A hereto from time to time upon the request of PNB. 
PNB shall request PageNet Services either in writing or orally if confirmed in
writing within 24 hours.  All PageNet Services will be supplied to PNB at the
earliest practicable time, with the understanding that although PageNet will
consider the provision of such services to PNB to be of the same importance as
the provision of such services by PageNet to its own operations, PageNet has
limited personnel resources that will have to be allocated by PageNet. PageNet
agrees to complete the requested PageNet Services as promptly as is reasonably
practicable in a professional manner, conforming to PageNet's standards. PageNet
shall have the sole and exclusive right to determine who shall perform the
PageNet Services (whether they be employees, subcontractors or others) and
PageNet shall have sole and complete authority for the direction of, and shall
remain responsible for, the PageNet Services to be performed.

    2.2. Costs and Expenses. The provision of PageNet Services hereunder shall
be without charge by PageNet, except that PageNet shall invoice PNB, and PNB
shall reimburse PageNet, for any out-of-pocket costs and expenses incurred by
PageNet in connection with the provision of PageNet Services, including, but not
limited to: (i) expenses of PageNet in connection with providing the employees
listed on Exhibit A hereto (such expenses to include those paid pursuant to its
expatriate policy and those, such as stock options (valued at the time of grant
according to the Black-Scholes Formula), benefits and contributions to its
401(k) plan, paid by agreement with such employees), and (ii) expenses relating
to PageNet personnel travel to and from, and accommodations and transportation
within, Brazil.  PageNet may request in writing to PNB that certain expenses in
connection with PageNet Services be paid directly by PNB to others.

    2.3. Invoicing. PageNet shall submit to PNB an invoice for monthly payments
due under Section 2.2 on before the tenth (10th) business day after the close of
such month. PNB shall pay the full amount set forth in such invoice, without
offset, on or before the thirtieth (30th) day after the receipt of the invoice
and in accordance with Section 6.

    Section 3.     License of PageNet Intellectual Property.

    3.1. Grant of License.

    (a)  PageNet hereby grants to PNB, and PNB hereby accepts, during the term
of this Agreement and thereafter to the extent and as provided in Section 3.5
hereof, an exclusive, royalty-free, nontransferable (except as otherwise
provided in Section 3.4 hereof) license (the "License") to use and otherwise
exploit in the Territory the trade names, trademarks and service marks owned by
PageNet and set forth on Exhibit B hereto (as said Exhibit B may be amended from
time to time) (the "Marks") and any trade secrets, patents, copyrights or other
intellectual property included in the Confidential Information disclosed or
provided by PageNet to PNB in connection with this Agreement (all of the
foregoing, including the Marks, collectively referred to herein as the "PageNet
Intellectual Property"), in connection with (and limited solely to) PNB's
advertisement, promotion, marketing, sale, development and provision of the
Telecommunication Services and products and services related thereto (all such
Telecommunication Services and related products and services referred to as the
"Licensed Services") in the Territory.  For purposes of this Agreement,
"exclusive" means that PageNet, (i) during the term of this Agreement, will
neither use itself nor grant to any third party a license to use the PageNet
Intellectual Property in connection with the advertising, promotion, marketing,
sale, development or provision of Licensed Services in the Territory, and
(ii) during the term of the License (and thereafter in accordance with and to
the extent provided in Section 3.5(e) hereof), will neither use itself nor grant
to any third party a license to use the Marks in connection with any products,
services or business activity in the Territory.

    (b)  The granting of the foregoing License shall in no manner whatsoever
limit the rights of PageNet, except as specifically provided in Sections 3.1(a)
and 3.5(e) hereof; and except as so provided PageNet hereby expressly reserves
full and unrestricted rights to use and exploit itself the PageNet Intellectual
Property, and to grant to others rights and licenses to use and exploit the
PageNet Intellectual Property, including without limitation the rights to use
and exploit itself and to grant to others licenses to use and exploit (i) the
PageNet Intellectual Property outside of the Territory in connection with any
products, services or business activities, and (ii) the PageNet Intellectual
Property (excluding the Marks) within the Territory other than for Licensed
Services.



                                       4

<PAGE>


    (c)  PNB acknowledges PageNet's sole and exclusive ownership of the PageNet
Intellectual Property and any and all registrations or applications with respect
thereto (whether issued by or filed with the relevant governmental authorities
in the Territory or otherwise), and that the provisions of this Agreement do not
convey to PNB and PNB shall not obtain any title to or ownership right or
interest in the PageNet Intellectual Property or any such registrations or
applications.  All use of the Marks by PNB in connection with the
Telecommunications Services or otherwise hereunder shall inure to the exclusive
benefit of PageNet.  Each party agrees, at the reasonable request of the other
party, to execute and deliver any and all instruments and documents deemed
necessary or desirable by the requesting party to develop, protect, preserve,
extend or enforce the parties' respective rights relating to the PageNet
Intellectual Property, including but not limited to any documents required by
the United States Patent and Trademark Office or the Brazilian National
Institute of Intellectual Property to show the relationship between PNB and
PageNet.

    (d)  It is the specific intent of the parties hereto that nothing contained
in this Agreement shall in any way endanger, jeopardize or adversely affect any
right of PageNet in and to the PageNet Intellectual Property.  To that end,
should any provision or provisions of this Agreement be interpreted by a court
or other governmental authority so as to endanger, jeopardize or adversely
affect such right or rights, whether or not such interpretation is made at the
instance of PNB or another, the parties agree that such provision or provisions
shall be deemed deleted from this Agreement, and the parties shall negotiate in
good faith to replace such deleted provision(s) with substitute provision(s)
which do not endanger, jeopardize or adversely affect such right(s) but which,
to the extent practicable, implement the purposes and intent of the parties as
set forth in the deleted provision(s).

    (e)  Subject to the prior written consent of PageNet, which consent will
not be unreasonably withheld or delayed, PNB shall have the right under the
License to grant to any third party (a "Sublicensee") a sublicense (a
"Sublicense"), to use and otherwise exploit in the Territory, the PageNet
Intellectual Property in connection with PNB's and/or such Sublicensee's
advertisement, promotion, marketing, sale, development and provision of Licensed
Services in the Territory.  The granting of any Sublicense by PNB pursuant to
this subsection (e) shall be subject to all of the following: (i) such
Sublicense shall be subject to the provisions of this Section 3, any Sublicensee
shall be subject to any and all of the obligations of PNB contained in this
Section 3, mutatis mutandis, and upon the request of PageNet any such
Sublicensee shall expressly acknowledge such obligations in a written instrument
delivered to PageNet; (ii) the granting of such Sublicense shall in no manner
whatsoever relieve, waive, or excuse the performance of, any of the obligations



                                           5

<PAGE>


and/or responsibilities of PNB with respect to the License or the provisions of
this Section 3; (iii) with respect to the granting of such Sublicense, PNB
covenants and agrees that it will take any and all steps, as may be necessary or
appropriate or as reasonably requested by PageNet, to ensure the full and
complete performance of, and compliance with, the obligations under such
Sublicense by such Sublicensee; (iv) any breach by such Sublicensee under such
Sublicense, which breach--if committed by PNB--would be a breach of the License,
shall be deemed a breach of the License and the provisions of this Section 3 by
PNB; and (v) any termination of the License hereunder (whether with respect to
the Marks, the PageNet Intellectual Property other than the Marks, or all of the
PageNet Intellectual Property) shall automatically terminate such Sublicense
with respect to the affected PageNet Intellectual Property.

    3.2. Quality Control; Compliance with Laws.

    (a)  PNB will not use the Marks without PageNet's express prior written
consent to such use, which consent will not be unreasonably withheld or delayed;
provided, however, that this Agreement shall constitute such prior written
approval of PageNet unless PageNet notifies PNB in writing that PageNet has
determined, reasonably and in good faith, that (i) the Marks have been or are
proposed to be used incorrectly from a technical standpoint (i.e., proper
trademark usage) or otherwise not in compliance with the License, or (ii) PNB's
actual or proposed use of the Marks would materially adversely affect the value
of the Marks or materially adversely affect PageNet's ability to register,
protect, preserve or enforce its rights and interests in the Marks (whether
inside or outside the Territory).  Copies or prototypes of all proposed Licensed
Services-related advertising, promotional, marketing, sales and operating
materials or items using and/or bearing the Marks will be submitted by PNB to
PageNet, a reasonable time prior to any use, sale or distribution of the same. 
If at any time PageNet, reasonably and in good faith, determines that any use
and/or display of the Marks by PNB is not in compliance with the License or does
or may materially adversely affect the value of the Marks or materially
adversely affect PageNet's ability to register, protect, preserve or enforce its
rights and interests in the Marks (whether inside or outside the Territory),
PageNet may issue instructions to PNB concerning the manner in which PNB may
continue to use the Marks in compliance with the License, and PNB will promptly
comply with such instructions or the parties will negotiate in good faith to
reach agreement on an alternative use and/or display of the Marks that complies
with the License and is reasonably acceptable to both parties.

    (b)  PNB shall advertise, promote, market, sell and provide the Licensed
Services in accordance with the terms of this Agreement and in a high quality,
professional manner consistent with the quality of similar services and/or
products either (i) provided by PageNet or others under the Marks in the United


                                         6

<PAGE>


States or other countries outside the Territory, or (ii) provided by significant
competitors of PNB or other significant such service providers  within the
Territory (taking into account the then-current commercial and technical
standards and capabilities then prevailing in the Territory), and, in either
case, consistent with the high quality, professional image of and goodwill
associated with the Marks and taking into consideration for a reasonable and
appropriate period the start-up nature of PNB's operations (all of the foregoing
referred to as the "Quality Standard").

    (c)  In order to ensure that the Licensed Services are provided in an
appropriate manner commensurate with the Quality Standard, PNB, upon reasonable
prior oral or written notice to PNB by PageNet, will allow representatives of
PageNet to make reasonable tests or inspections of the Licensed Services, and to
have access to PNB premises or facilities at any reasonable time during business
hours; provided, however, that PNB shall not be required to allow any such
tests, inspections or access more than twice in any one-year period.  In
connection therewith, PNB shall make available to such representatives any
facilities, equipment, services or information reasonably requested and permit
such representatives to test or inspect the Licensed Services and to inspect its
premises and facilities and any and all items and/or materials provided to
customers or others in connection with the Licensed Services at any reasonable
time during business hours, and PNB shall otherwise cooperate with PageNet as
PageNet may reasonably request.  

    (d)  If PageNet reasonably determines that the Licensed Services (or any
portion thereof) do not meet the Quality Standard, then PageNet will provide PNB
with written notice (the "Defect Notice") of such failure, specifying the
specific product or service and the particular deficiency, and (if applicable)
the relevant geographic region of the Territory, together with any reasonably
available supporting documentation of such deficiency.  If PNB shall not have
met such Quality Standard for such specific product or service and does not
(i) take appropriate action to diligently commence to cure such deficiency
within sixty (60) days after receipt of the Defect Notice, and (ii) cure such
deficiency by causing such product or service to meet such Quality Standard and
provide documentation of such cure reasonably acceptable to PageNet within
ninety (90) days after receipt of the Defect Notice (or, if such deficiency is
not reasonably susceptible to cure within such 90-day period, within one hundred
eighty (180) days after the receipt of the Defect Notice), then PageNet may, by
written notice to PNB (the "Suspension Notice"), immediately suspend the License
of the Marks only with respect to the particular product or service (and the
relevant geographic region, if applicable) specified in the Defect Notice, and
PNB shall as promptly as possible cease all use of the Marks with respect to
such particular product or service (in such geographic region, if applicable). 
As long as the License remains in effect hereunder with respect to the Marks, if
at any subsequent time PNB demonstrates, to PageNet's reasonable satisfaction,


                                       7

<PAGE>

that such particular product or service (with respect to which the License of
the Marks had been suspended) then meets the Quality Standard (in the relevant
geographic area, if applicable), then the License of the Marks shall be
reinstated and once again in effect with respect to such product or service (in
the relevant geographic area, if applicable).  However, if PageNet sends more
than three (3) Suspension Notices in any period of twenty-four (24) months or
less with respect to separate violations of the Quality Standard, PageNet shall
have the right, by written notice to PNB, immediately to terminate the License
of the Marks (only) provided herein.

    (e)  In connection with its use of the Marks and its advertisement,
promotion, marketing, sale and provision of the Licensed Services, PNB shall, at
all times during the term of this Agreement and thereafter during the term of
the License, comply in all material respects with all applicable laws and
regulations, including, without limitation, the Brazilian Regulations and any
other terms or conditions that may be imposed by the Brazilian Regulators, any
of their successor departments or agencies, or any other departments or agencies
serving the same or similar function, and any state or local agencies.

    3.3. Infringement and Adverse Governmental Action.  Each of PageNet and PNB
will promptly notify the other party of any infringement or misappropriation and
of any adverse governmental action or the commencement of any legal action by a
third party relating to the PageNet Intellectual Property or the Licensed
Services within the Territory, of which it becomes aware.  Each party shall also
notify the other party of any other factor of which it becomes aware that may
materially affect the PageNet Intellectual Property or the provision of the
Licensed Services.  PNB shall have the right, exercisable at its option and with
notice to PageNet, (a) to prosecute any and all actions against alleged
infringers or misappropriators of the PageNet Intellectual Property and/or
defend the PageNet Intellectual Property against any and all claims or actions
made or brought by third parties with respect thereto within the Territory, and
(b) to seek to remedy governmental actions adversely affecting the PageNet
Intellectual Property or the provision of the Licensed Services in the
Territory; PageNet will cooperate in any action brought or defended against by
PNB within the Territory, at PNB's request and expense.  If PNB does not
commence to prosecute, defend against or seek to remedy any of the foregoing
actions within ninety (90) days after PNB becomes aware thereof, then PageNet
shall have the right, exercisable at its option and with notice to PNB, to
prosecute, defend against or seek to remedy any such actions; PNB will cooperate
in any action brought or defended against by PageNet within the Territory, at
PageNet's request and expense.  Each party will bear the costs of its own legal
expenses and other costs in connection with any actions taken, and the party
bearing the costs will be entitled to receive any amounts received in settlement
and/or damages awarded.  

                                       8

    3.4  Assignment or Transfer of the License.  

    (a)  Except as provided in Sections 3.4(b) and (c), PNB shall not have the
right to assign or transfer the License to any third party, whether by sale or
assignment of assets or stock, merger consolidation or otherwise.

    (b)  As long as this Agreement remains in full force and effect, PNB shall
have the right to assign or transfer the License in conjunction with any
permitted assignment or transfer of this Agreement pursuant to Section 13.1
hereof.

    (c)  At any time upon or subsequent to a termination of this Agreement
whereby the provisions of this Section 3 have survived such termination and
PageNet has not terminated the License (either with respect to the Marks only or
the entire License) pursuant to Section 3.5, then PNB shall have the right to
assign or transfer the License, with respect to the PageNet Intellectual
Property for which the License remains in effect at the time of such assignment
or transfer, to any third party to which PNB shall simultaneously assign or
transfer all or substantially all of PNB's assets (other than this Agreement)
associated with its Licensed Services business (however such assignment or
transfer is structured, e.g., as an assignment of assets, sale of stock, merger,
consolidation, or otherwise), provided that both of the following conditions are
satisfied prior to or at the time of such assignment or transfer: (i) such
assignee or transferee shall be subject to any and all of the obligations of PNB
contained in this Section 3, mutatis mutandis, and shall expressly acknowledge
such obligations in a written instrument delivered to PageNet; and (ii) such
assignee or transferee represents and warrants to PageNet, in writing, that it
is such party's intention itself to continue to carry on and conduct the
Licensed Services business being acquired by such party from PNB.  

    3.5. Effect of Termination.

    (a)  Notwithstanding anything in this Agreement to the contrary, the
provisions of this Section 3 shall survive termination of this Agreement, other
than: (i) a termination pursuant to Section 10.1; or (ii) a termination
initiated by PageNet pursuant to Section 10.2 where the relevant breach or
default by PNB is a breach or default under the terms of the License set forth
in this Section 3; or (iii) a termination pursuant to Section 10.3 if such
termination is on account of governmental action which requires a termination of
the License, provided, however, if such governmental action (with respect to its
required termination of the License) is reversed within the period up to and
including the first anniversary of the date of such termination pursuant to this
clause (iii), PNB shall have the right to reinstate the License by delivery to
PageNet of written notice of such reversal and reinstatement within such time
period or up to five (5) business days thereafter, whereupon the provisions of
this Section 3 shall be reinstated and revived and in full force and effect.  In
the event of any post-termination survival and/or reinstatement of this Section


                                        9

<PAGE>

3, the License shall remain exclusive only with respect to the Marks and shall
become non-exclusive with respect to any and all other PageNet Intellectual
Property (as provided in Section 3.1(a)).

    (b)  At any time subsequent to a termination of this Agreement whereby the
provisions of this Section 3 have survived such termination (or been reinstated
pursuant to Section 3.5(a)(iii)) and remain in full force and effect pursuant to
Section 3.5(a), PageNet may thereafter (i) partially suspend or terminate the
License of the Marks (only) pursuant to Section 3.2(d), or (ii) terminate the
License if PNB commits any breach or default of any of the terms or conditions
of the License (other than a breach or default to which Section 3.2(d) applies)
and such breach or default has not been cured within ninety (90) days after
receipt by PNB of PageNet's notice of such breach or default (or, if such breach
or default is not reasonably susceptible to cure within such 90-day period,
within one hundred eighty (180) days after receipt by PNB of PageNet's notice of
such breach or default).

    (c)  Upon any termination of the License of the Marks, whether pursuant to
Section 3.2(d) or Section 3.5(b), then:

         (i)  all rights and licenses granted hereunder by PageNet to PNB
(including but not limited to the License) with respect to the Marks shall
terminate, and PNB shall have no claim against PageNet for losses or expenses
incurred or for lost profits or goodwill;

         (ii) PNB shall promptly cease entirely the use of all of the Marks;

         (iii) PNB shall promptly change its corporate name from "Paging
Network do Brasil S.A." to "Warburg Paging do Brasil S.A." or such other
corporate name as long as such name does not include, is not similar to or
likely to be confused with, and is not a colorable imitation of any of the
Marks, and PNB shall file with the appropriate Brazilian authorities the
necessary documentation in connection with such name change within thirty (30)
days following the date of any such termination;

         (iv) in order to protect and preserve PageNet's rights in and the
identity of the Marks, PNB agrees that it will not use or register or apply to
register any trademark or trade name which is similar to or likely to be
confused with or is a colorable imitation of the Marks; and

         (v)  subsections (iii) and (iv) are intended to prevent confusion,
mistake or deception among purchasers of and users of the same or related

                                       10

<PAGE>


goods or services which might be caused by the same or similar corporate 
names, trademarks or trade names.

    (d)  If the License (in its entirety) is terminated pursuant to Section
3.5(b), or if this Agreement is terminated pursuant to Section 10.1, pursuant to
Section 10.2 at the initiation of PageNet where the relevant breach or default
by PNB is a breach or default under the terms and conditions of the License set
forth in this Section 3, or pursuant to Section 10.3 if such termination is on
account of governmental action which requires a termination of the License and
PNB does not reinstate the License pursuant to Section 3.5(a)(iii), then in
addition to the application of clauses (i) - (v) of Section 3.5(c):

         (i)  all rights and licenses granted hereunder by PageNet to PNB
(including but not limited to the License) shall terminate, and PNB shall have
no claim against PageNet for losses or expenses incurred or for lost profits or
goodwill; and

         (ii) PNB shall promptly cease entirely the use of all of the PageNet
Intellectual Property.

    (e)  Upon any termination of the License with respect to the Marks (whether
alone or as part of a termination of the License with respect to all the PageNet
Intellectual Property), PageNet shall not, for a period of two (2) years
immediately following such termination, either directly itself or indirectly
through a licensee, use the Marks in the Territory for or in association with
any Licensed Services.

    Section 4.     Equipment Purchase Option.

    4.1.  Procurement of Equipment. PageNet agrees to use its commercially
reasonable efforts to arrange with vendors to furnish to PNB equipment relating
to the operation of the Telecommunications Services in the Territory (the
"Equipment"), as and when requested by PNB to PageNet in writing from time to
time, at prices and terms (including but not limited to financing and
cooperative advertising) as favorable to PNB as PageNet is able to obtain for
such Equipment for itself. If such favorable prices and terms cannot be secured,
PageNet shall use its commercially reasonable efforts to order such Equipment
from vendors on PNB's behalf with the vendors directly billing PNB therefor. At
PNB's request, PageNet shall use its commercially reasonable efforts to have
vendors extend credit to PNB for Equipment purchased either directly by PNB or
by PageNet on behalf of PNB; provided, however, that under no circumstances
shall PageNet be obligated to use its own credit with vendors to procure
Equipment for or on behalf of PNB. If Equipment ordered by PageNet for or on
behalf of PNB is actually invoiced by vendors to PageNet, PageNet shall
immediately forward such invoice to PNB and PNB shall directly pay such


                                       11

<PAGE>

invoice in accordance with its terms. If, for any reason, PageNet, in its 
sole discretion (a) pays vendors with its own funds, or (b) uses its own 
credit with vendors to obtain Equipment for or on behalf of PNB, PageNet 
shall advise PNB in writing of such payment or credit arrangement along with 
appropriate documentation and PNB shall reimburse PageNet for the price 
actually paid or to be paid by PageNet for such Equipment, including all 
shipping, handling, insurance, taxes, duties and other charges, in accordance 
with the provisions of Sections 4.2 and 6.

    4.2.  Invoicing. PageNet shall submit to PNB an invoice for Equipment
purchased or procured by PageNet for or on behalf of PNB under Section 4.1 on or
before the tenth (10th) business day after the close of the month during which
such Equipment was ordered. PNB shall pay the full amount set forth in such
invoice, without offset, on or before the fifth (5th) business day prior to the
date that the vendor of the Equipment has required payment and in accordance
with Section 6. If the vendor has other requirements for payment, such as
C.O.D., PNB shall comply with such payment terms as if it were the direct
purchaser of the Equipment.

    4.3  Warranties. If PageNet shall purchase any Equipment on behalf of PNB,
PageNet shall, to the extent possible, pass through to PNB all warranties
provided by the vendor of such Equipment, and, if the vendor does not permit
PageNet's pass through of such warranties, PageNet will use its best efforts to
enforce such warranties on behalf of PNB. PageNet and PNB shall work together to
preserve any benefits that PageNet would receive from the vendor as the
purchaser of the Equipment.

    4.4.  Shipping. To the extent possible, the Equipment shall be shipped and
delivered in accordance with PNB's instructions. If for any reason PageNet must
take delivery of and reship Equipment to PNB, any additional expenses in
connection therewith shall be invoiced by PageNet to PNB, and PNB shall pay such
invoices in the manner set forth in Section 6. PageNet shall use commercially
reasonable efforts to arrange shipping, delivery and title transfers so as to
minimize duties and other import levies.

    4.5.  Relationship between PageNet and PNB.  As between PageNet and PNB, it
is intended by the parties that PageNet's role as a facilitator of purchases of
the Equipment by PNB is ministerial and that PNB is to be considered the
purchaser of the Equipment even if PageNet must purchase the Equipment in its
name for and on behalf of PNB. Therefore, PageNet assumes no risk by acting in
this capacity. Consistent with the foregoing, but not in limitation thereof, all
risk of loss on all Equipment shipped by any vendor or PageNet shall be borne by
PNB and not PageNet (even if delivered to PageNet).

    Section 5.     Disclaimer: Limitation of Liability and Damages.

    ALL EQUIPMENT PROCURED, PURCHASED, SUPPLIED OR INSTALLED BY PAGENET FOR PNB
IS PROVIDED TO PNB ON AN "AS IS" BASIS, WITHOUT ANY REPRESENTATION OR WARRANTY
OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. PageNet
shall not be liable for any delay in the performance of orders or contracts for
Equipment, or for any delay in the shipment or delivery thereof, or for any
direct or indirect damages suffered by PNB by reason of such delays.

    Section 6.     Payments, Taxes and Exchange Control.

    All payments by PNB hereunder shall be made in United States Dollars (or,
if requested by PageNet, in Brazilian Reais at the prevailing exchange rate on
the date of payment) in immediately available funds. Payments to PageNet shall
be made to the address set forth in Section 13.2 or at such other address as
PageNet may specify from time to time. PNB shall, at its own expense, be solely
responsible for obtaining all governmental and non-governmental approvals
required or necessary for the prompt and complete remittance of payments under
this Agreement. All payments shall be made in the full and actual amounts
invoiced and no deductions shall be made for of any direct or indirect taxes,
duties, fees, costs, expenses, commissions, contributions, surcharges or other
amounts of any kind that may be imposed or required on such payments by any
third party (including but not limited to governmental authorities or financial
institutions) (all of such amounts, the "Charges"). PNB shall be solely
responsible for the prompt and complete payment of all Charges. PageNet shall
assess a late charge of one and one-half percent (1.5%) per month, or at
PageNet's sole discretion, the highest applicable rate permitted under
prevailing law, on any amount due from PNB to PageNet which is not received when
due for payment.

    Section 7.     Regulations.

    PageNet and PNB acknowledge that the activities of PNB and/or its
Affiliates in connection with the operation of Telecommunications Services in
the Territory hereunder are subject to the Brazilian Telecommunications Code and
other applicable laws (all of such laws, statutes, orders, rules and
regulations, together the "Brazilian Regulations") and are regulated by the
Ministry of Communications of Brazil and other Brazilian regulatory agencies and
governmental authorities (all such regulatory entities or authorities, together
the "Brazilian Regulators"). Accordingly, PageNet and PNB mutually agree as
follows:

                                        13

<PAGE>


    7.1. Consents. The execution, delivery and performance of this Agreement
and the transactions contemplated hereby may be subject to the receipt of any
necessary prior approvals or authorizations by or from the Brazilian Regulators
or any other governmental authority. PageNet and PNB agree to use their best
efforts to promptly obtain any such approvals or authorizations applicable to
them. PNB shall, at its own expense, be responsible for obtaining all Brazilian
approvals for the importation of Equipment or relocation of persons necessary to
perform the PageNet Services into the Territory.

    7.2. Compliance. PageNet and PNB shall each comply, in all material
respects, with all Brazilian Regulations and all applicable laws and regulations
of the United States of America. In the event Brazilian Regulators or any
governmental authority shall require any material additions, deletions, or
modifications to the terms or conditions of this Agreement, PNB and PageNet
shall use commercially reasonable efforts to reconstitute this Agreement to
comply with such requirements.


    7.3. Records. Each of PNB and PageNet shall maintain complete and accurate
records regarding its business activities, showing the information required (i)
to permit calculation of all amounts owed hereunder by PNB to PageNet, (ii) to
permit the verification of costs and expenses referred to in Section 2.2, and
(iii) to compile any information required by the Brazilian Regulators or any
other governmental authority. Each of PNB and PageNet shall have the right, at
its own expense, to examine (or to have its duly authorized agent examine) on a
confidential basis and upon at least ten (10) days prior notice thereof such
records and books of account with respect to operation of the Telecommunications
Services in the Territory of the other during regular business hours.

    7.4. Control of Radio Facilities. PageNet acknowledges that PNB has, or has
entered into agreements with others to obtain, the rights to operate the
frequencies and facilities necessary to re-sell Telecommunications Services in
the Territory.  PNB shall ensure that the frequencies and facilities are
operated in compliance with the Brazilian Regulations.  No provision of this
Agreement shall be construed as vesting in PageNet any control over legal
entities holding concessions or licenses for the operation of frequencies or
facilities utilized to re-sell Telecommunication Services in the Territory by
PNB.  PNB shall take all actions necessary to ensure that all of the terms and
conditions of the licenses are complied with and fulfilled and the frequencies
remain available for the operation of Telecommunication Services in the
Territory by PNB.  PNB shall maintain full responsibility for the control,
supervision, maintenance, and expense of such operation of frequencies and
facilities.  PNB shall promptly notify PageNet of any complaints received from
End-users relating to the 


                                     14

<PAGE>


operation of Telecommunications Services in the Territory and shall confirm 
such complaints to PageNet in writing.

    Section 9.     Term.

    9.1. Initial Term.  The initial term of this Agreement shall commence on
the date hereof and shall continue until the fifth (5th) anniversary of the date
hereof. The initial term shall be extended for successive three (3) year terms

    9.2. Termination Under Certain Circumstances.

    (a)  Notwithstanding the provisions of Section 9.1, this Agreement shall

    Anything set forth herein to the contrary notwithstanding, this Agreement
may be terminated by PNB or PageNet as provided below by the giving of written
notice of such termination by the terminating party at least thirty (30) days in
advance:

    10.1.     Non-Payment. PageNet may terminate this Agreement if PNB has
failed to pay any amounts due under Sections 2 and 4, and such failure continues
for a period of thirty (30) days after the receipt by PNB of notice of
non-payment from PageNet; provided, however, that any such termination by
PageNet shall not terminate the License pursuant to Section 3 hereof, if PNB
reasonably and in good faith disputes its obligation to pay PageNet the amount
not paid (as evidenced by written notice given by PNB to PageNet within such
30-day period setting forth the amount in dispute and PNB's reasonable and good
faith basis for disputing such obligation), unless and until such dispute is
resolved (whether by agreement, settlement, mediation, arbitration decision,
court decision or otherwise) and PNB shall not have paid PageNet the amount (if
any) which PNB is obligated to pay pursuant to such resolution within thirty
(30) days after the effective date of such resolution.

    10.2.     Breach. Either party may terminate this Agreement if the other
party commits a material breach or default of any of the provisions of this
Agreement (other than actual or potential material breaches or defaults to

                                         16

<PAGE>

which Section 3.2(d) hereof applies) and such breach or default has not been 
cured within thirty (30) days after receipt by the breaching party of the 
non-breaching party's notice of such breach or default. Either party may 
terminate this Agreement if the other party commits any other breach or 
default of any of the provisions of this Agreement (other than actual or 
potential other breaches or defaults to which Section 3.2(d) hereof applies)

Agreement if the performance of this Agreement pursuant to the terms hereof has

authority or regulatory body, by a final, nonappealable rule, decision, order or
law and the parties are unable to reconstitute this Agreement pursuant to
Section 13.4.

    10.4.     Consequences of Termination.  The termination of this Agreement

against all claims, damages and liabilities resulting from the failure by
PageNet to perform its obligations hereunder.  Notwithstanding any provision of
this Agreement, in no event shall PageNet nor its directors, officers, employees
or agents be liable for any loss of profits, loss of business, loss of goodwill,
indirect, special, exemplary, consequential or punitive damages that may be
suffered by PNB, its directors, officers, employees' agents or End-users arising

or any legal theory.

    11.2.  PNB Indemnity.  PNB shall indemnify and hold harmless PageNet, its
Affiliates, their respective directors, officers, employees, agents,
subsidiaries, affiliates, subcontractors and assignees, or any of them, from and
against all claims, damages and liabilities resulting from PageNet's performance
of its obligations hereunder and from the acts or omissions of PNB or the

                                       17

<PAGE>

failure by PNB to perform its obligations hereunder or any acts or omissions
associated therewith.  

    Section 12.    Confidentiality.

    All Confidential Information made available by one party (the "Disclosing
Party") to the other party (the "Receiving Party") in connection with this
Agreement shall be held in strict confidence by the Receiving Party for a period
extending through the date five (5) years from the expiration or termination of
this Agreement, provided that such Confidential Information continues to be

      adverse effect on the ability of the PROMISING TRANSFEROR to consummate
      the transactions contemplated hereby.

      Clause Six: REPRESENTATIONS AND WARRANTIES OF THE PROMISING TRANSFEREE

      First Paragraph: The PROMISING TRANSFEREE is a corporation (S.A.) duly
      organized, validly existing and in good standing under the laws of the
      Federative Republic of Brazil and has full corporate power and authority

                                                                               6
<PAGE>

      standing in each jurisdiction in which the ownership of its properties or
      the conduct of its business requires such qualification.

      Second Paragraph: The PROMISING TRANSFEREE has all necessary corporate
      power and authority and has taken all corporate action necessary to enter
      into this Agreement, to consummate the transactions contemplated on its
      part hereby and to perform its obligations hereunder. The execution,
      delivery and performance or this Agreement and the consummation of the
      transactions described herein by the PROMISING TRANSFEREE have been duly
      authorized by all requisite corporate action. This Agreement has been duly
      executed and delivered by the PROMISING TRANSFEREE and, assuming the due
      execution and delivery thereof by the PROMISING TRANSFEROR, is a valid and
      binding obligation of the PROMISING TRANSFEREE, enforceable against it in
      accordance with its terms, except as such enforceability may be limited by
      bankruptcy, insolvency, reorganization, moratoriums or other similar laws
      now or hereafter in effect relating to creditors, rights generally and by
      general principles of equity (whether considered in an action at law or in
      equity) and the discretion of the court before which any proceeding
      therefor may be brought.

Clause Seven: MUTUAL COVENANTS OF THE PARTIES

      First Paragraph: From the date hereof until the date upon which the
      definitive agreement(s) for the transfer of the Permissions are executed,
      the PROMISING TRANSFEROR shall:

      (a)   not take any action that would result in the rescission of the grant
            of the Permissions to the PROMISING TRANSFEREE, or any action
            inconsistent with the consummation of the transactions contemplated
            hereby;

      (b)   take all action necessary to maintain good title to the Permissions
            and the Rights, including using its best efforts to preserve
            generally the present relationships with persons or governmental
            agencies instrumental in the granting of the Permissions;
            instructions for such actions shall be given by the PROMISING
            TRANSFEREE to the PROMISING TRANSFEROR; or

      (c)   not sell, transfer or otherwise dispose of any of the Permissions or
            Rights or permit any lien, charge, pledge, mortgage, security
            interest or other encumbrance of any kind to exist thereon.


                                                                               7
<PAGE>

      Second Paragraph: From the date hereof until the date upon which the
      definitive agreement(s) for the transfer of the Permissions are executed,
      the PROMISING TRANSFEREE shall not take any action inconsistent with the
      consummation of the transactions contemplated hereby.

Clause Eight: CONSIDERATION

      8.1.  As consideration for the transfer of all the Permissions, now
            promised, the PROMISING TRANSFEROR shall be entitled to the increase
            of value of its assets and rights arising from technological,
            organizational, operational and managing goodwill developed by the
            PROMISING TRANSFEREE, in accordance with the Operating Agreement.

      8.2.  The increase of value to which the PROMISING TRANSFEROR shall be
            entitled is that verified from the date hereof until the date upon
            which all the Permissions have been transferred to the PROMISING
            TRANSFEREE, by means of a direct or indirect mechanism of transfer.

      8.3.  The failure of the Promising Transferee to complete the assignment
            and transfer now agreed, once the regulatory term has elapsed and
            the approval of the competent authorities is obtained, and provided
            that the breach was not a result of the action or inaction of the
            government or of a regulatory authority, such as the Ministry of
            Communications of Brazil, but of the PROMISING TRANSFEROR fault,
            shall give rise to the forfeit of its right to such increase of
            value of its assets and rights.

Clause Nine: JURISDICTION

      9.1.  This Agreement and all questions arising in connection with its
            interpretation and legal relations between the parties in connection
            herewith shall be governed and construed in accordance with the
            substantive law of Brazil.

      9.2.  All disputes and differences arising from or in connection with this
            Agreement, or in relations between the parties with respect to the
            subject matter hereof, shall be finally settled by binding
            arbitration in accordance with the Rules for Conciliation and
            Arbitration of the International Chamber of Commerce (ICC) by three
            arbitrators 


                                                                               8

            appointed in accordance with said Rules. The place of arbitration
            shall be New York, New York, and the arbitration proceedings shall
            be conducted in English.

      9.3.  If for any reason, notwithstanding the international character of
            this Agreement and the diverse nationalities of the shareholders in
            the companies parties to the same, the preceding clause 9.2. should
            not be applied or be held invalid by any court in Brazil or in the
            United States of America, the parties specifically agree that any
            dispute or controversy relating to this Agreement or otherwise
            described in clause 9.2. shall be decided solely and exclusively by
            the competent courts of the State of New York, United States of
            America.


                                                                               9
