Overview

   We seek to become a leading facilities-based provider of high capacity, high
speed Internet, data and voice services in the major urban markets throughout
Latin America. Through local fixed wireless access networks which we own and
operate, we currently provide broadband (i.e., high capacity, high speed) data
transport and dedicated Internet access to large and medium-sized businesses,
telecommunications carriers, Internet service providers, Internet content
providers, e-commerce providers and systems integrators. We currently offer Web
hosting services and are investing substantially in Internet infrastructure to
enable us to provide advanced Web hosting, co-location, facilities-based
Internet transport services and other enhanced Internet services on a large
scale. We also intend to complement our broadband Internet and data offerings
with voice services.

   We have obtained substantial regional and national grants of spectrum as
well as telecommunications operating licenses in Argentina, Brazil, Colombia,
Panama, Peru and Uruguay, covering a total population of more than 135 million
people. In addition, we have obtained voice operating licenses in Argentina and
Peru. We are currently in various stages of designing, building and operating
local fixed wireless broadband access networks in 16 major urban markets in
those six countries. We have launched commercial service in Buenos Aires,
Argentina, Sao Paulo, Brazil, and Bogota, Colombia. At December 31, 1999, we
had 309 employees, 219 buildings on our networks and 102 customers with 1,516
dedicated data and Internet circuit equivalents in service. We count circuit
equivalents on the basis of 64 kilobits per second per circuit. The 102
customers in December 1999 represented an increase of 89 from 13 customers in
March 1999. In addition, for the year ended December 31, 1999 we had revenues
of $1,143,000, an increase of $1,119,000 from $24,000 for the year ended
December 31, 1998.

Market Opportunities in Latin America

   We intend to capitalize on the increasing demand for broadband data and
Internet services in the major urban markets in Latin America. An industry
report, commissioned by us and dated April 1999, estimates that in Buenos
Aires, Sao Paulo and Bogota, revenues for dedicated Internet access and
dedicated broadband access will grow in the aggregate compounded annual rates
of 77% and 73%, respectively from 1999 to 2004. Another industry report dated
August 1999 estimates that Web hosting and co-location services related revenue
in Argentina, Brazil and Colombia in the aggregate will grow at a compounded
annual rate of 58% from 1999 to 2004.


Our Competitive Strengths

   We believe that we distinguish ourselves through several competitive
strengths, including:

  . Pan regional presence and holdings. We have secured one of the largest
    holdings of broadband wireless spectrum and regional and national
    operating licenses in Latin America. We also have established an early
    presence in major urban markets in Latin America, particularly in Brazil
    and Argentina.

                                       1
<PAGE>


  . Fixed wireless broadband access technology. We primarily use fixed
    wireless broadband access technology to enable us to quickly deploy our
    local networks on a cost-effective basis. We are also building and
    leasing fiber optic cable to increase the backbone capacity of our local
    networks in certain markets.

  . Flexible owned and operated networks. As a facilities-based provider, we
    are able to control the quality, capacity and availability of our
    broadband data, dedicated Internet access and enhanced Internet services.

  . Focused sales, marketing and customer service. We have built and continue
    to develop a targeted sales and marketing approach as well as proactive
    customer service groups in each market.

  . Proven management. We effectively combine the substantial experience that
    our corporate management team has obtained in the competitive U.S.
    telecommunications and data industries with the local knowledge, contacts
    and expertise of our in-country management and sales forces.

  . Strong investor and strategic vendor relationships. We have strong equity
    investors, including Goldman Sachs Capital Partners, Alta Communications,
    Norwest Equity Capital, Texas Pacific Group/Newbridge Latin America and
    Rothschild, as well as strong strategic and financing relationships with
    Ericsson and Lucent.

Business Strategy

   Our objective is to be a leading facilities-based provider of broadband
Internet, data and voice services in the major urban markets throughout Latin
America. Our strategy consists of the following key initiatives:

  . Accelerate the development of current markets and the roll-out of
    additional markets by leveraging our substantial spectrum holdings,
    significant operating rights and experience in entering new markets.

  . Lead with dedicated Internet and broadband data services and complement
    with staged introduction of voice services.

  . Expand our large and medium-sized business customer base through a
    focused direct sales force, third-party alliances and proactive customer
    service.

  . Invest substantially in Internet infrastructure to provide enhanced
    Internet services.

  . Pursue strategic acquisitions, partnerships and joint ventures to
    accelerate growth and complement our service offerings.

  . Continue to attract, retain and motivate skilled Latin American and U.S.
    personnel by granting stock options to all employees.

Local Fixed Wireless Broadband Access Networks

   We are currently in various stages of designing, building and operating
local fixed wireless broadband access networks in 16 major urban markets
throughout Latin America. We have built out local networks and launched
operations in Buenos Aires, Sao Paulo and Bogota and plan to launch operations
in Rio de Janeiro, Brazil, Belo Horizonte, Brazil, Lima, Peru and Panama City,
Panama by the end of 2000.


                                       2
<PAGE>

   We primarily use fixed wireless broadband access technology as a high
quality alternative to copper and fiber-based systems because it enables us to
quickly deploy our local networks on a cost-effective basis. We believe that
our costs to launch service in a market and to connect each customer are lower
than for providers using copper or fiber-based networks. Fixed wireless
technology enables our start-up costs for each new market to be only
approximately 25% of our expected total costs for that market and our
subsequent capital expenditures to be success-based, meaning that we do not
incur significant capital expenditures until we have identified sufficient
customer demand. As demand for service grows in each market, we will increase
the backbone capacity of our local networks by adding fixed wireless links or
building or leasing fiber optic cable.

Internet Infrastructure

   We are investing substantially in Internet infrastructure to enable us to
offer Web hosting, co-location, facilities-based Internet transport services
and other enhanced Internet services on a large scale. Our planned investment
includes constructing Internet data centers, securing high quality national and
international Internet connections and hiring additional skilled personnel.

Recent Developments

   On March 29, 2000, we raised $127 million in private equity financing. The
investors in this financing included a new investor to the company, Texas
Pacific Group/Newbridge Latin America, as well as several of our existing
investors including Goldman Sachs Capital Partners, Booth American, Columbia
Management, Meritage Private Equity Fund, Norwest Equity Capital and
Rothschild. The completion of this financing brought our total funded equity
capital raised since inception to over $273 million.

   On February 25, 2000, we entered into an agreement to acquire INEA Internet,
S.A., a company that offers Internet access and related services to businesses
in Buenos Aires. The total purchase price is approximately $8 million,
consisting of cash, notes and stock. INEA had revenues of $2.2 million for the
year ended December 31, 1999. We expect that this transaction will close in
April 2000.

   On March 31, 2000, we entered into an agreement to acquire two companies
that hold certain spectrum and operating rights in Colombia and Peru from
VeloCom, Inc. for $8.25 million in cash. We expect that this transaction will
close in April 2000.

   On March 23, 2000, we entered into an agreement with Thomson-CSF Systems
Argentina S.A. to acquire certain assets consisting of ongoing contracts to
provide primarily broadband access services in Buenos Aires to large and
medium-sized businesses for a purchase price of up to approximately $3 million
in cash. We expect that this transaction will close in May 2000.

                                ---------------

   We were incorporated as a Delaware corporation in October 1996 under the
name Diginet Americas, Inc, and in March 2000, we changed our name to Diveo

New Mexico Avenue, N.W., Suite 320, Washington, D.C. 20016 and our telephone

                                  RISK FACTORS

    You should carefully consider the risks described below before making an
investment decision. The risks and uncertainties described below are not the
only ones facing our company. Additional risks not presently known to us or
that we currently believe to be immaterial may also impair our business
operations.

    Our business, financial condition and results of operations could be
materially adversely affected by any of the following risks. The trading price
of shares of our common stock could decline due to any of these risks, and you
might lose all or part of your investment.

    This prospectus also contains forward-looking statements that involve risks
and uncertainties. Our actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including the risks faced by us described below or elsewhere.

We have had operating losses since our inception, and we expect to continue to
experience operating losses in the next several years.

    We have had significant operating losses and negative cash flow from
operations since our inception. For the year ended December 31, 1999, we had a
loss from operations of $26.6 million and a net loss of $24.9 million. We
expect to continue to incur significant operating losses and have negative cash
flow from operations in the future as we build out our local fixed wireless
broadband access networks and make substantial investments in Internet
infrastructure. If our revenues do not increase significantly, we may not
achieve or sustain profitability or generate positive cash flow.

Our limited history of operations may make it difficult to evaluate our
prospects.

    Our company was formed in October 1996. As of March 31, 2000, we have
commenced operations in three markets and have only limited operating
experience in those markets. In addition, we are only beginning to make the
substantial investments in Internet infrastructure necessary to enable us to
provide enhanced Internet services on a large scale. Accordingly, prospective
investors have limited historical financial and operating information to use in
evaluating our performance and determining whether they should purchase our
common stock.

Our success depends on market acceptance of, and customer demand for, our
services, and we are only beginning to introduce many of the services that we
expect to offer.

    Our success will depend heavily on the extent to which prospective
customers use our services. For us to succeed, demand for existing services
must increase significantly and there must be strong demand for the enhanced
Internet services we intend to introduce in the future. Demand for such
services in our markets in Latin America, however, is uncertain and our success
in creating demand will be subject to business, economic, regulatory and
competitive factors that are beyond our control. Moreover, demand for our
existing and planned services at price levels that will permit us to become
profitable in the long term or to sustain profitability is uncertain.

We may have to delay or abandon our business plan if our anticipated
significant future capital requirements exceed the capital available to us.

    We will require significant amounts of additional capital to fund our
business plan. We estimate that we will need at least $275 million in 2000 to
fund:

  . deployment of our local fixed wireless broadband access networks,
    including the costs to build and lease fiber optic cable to increase the
    capacity of the backbone of our local networks;

                                       7
<PAGE>

  . substantial investments in Internet infrastructure to offer enhanced
    Internet services; and

  . new opportunities, including acquisitions of businesses or investments
    in, or strategic alliances with, companies that are complementary to our
    current or planned operations.

The actual amount and timing of our future capital requirements may differ
materially from our estimates as a result of prevailing economic conditions and
financial, business and other factors, many of which are beyond our control. We
cannot assure you that the capital actually required to complete our network in
our initial target markets will not exceed our expectations. If demand in these
markets exceeds current expectations, our capital requirements may increase
materially. In addition, we may identify new markets in the future and, as
opportunities develop, we may be required to make additional investments in our
networks and facilities or pursue strategic alliances to consummate those
opportunities.

    If required, we expect to raise additional capital through the sale of debt
and equity securities and through vendor financing. We cannot assure you that
we will be able to raise sufficient capital or that such funding will be
available on a timely basis or on terms acceptable to us, if at all. If we
raise capital through the sale of equity securities, you may experience
substantial dilution. If we fail to raise additional funds when and if
required, we may have to delay or abandon expansion of our network into certain
markets, which could prevent revenue growth and would hinder our ability to
compete.

We face significant competition throughout Latin America.

    We face varying degrees of competition in each of our markets, and we
expect to encounter increasing competition in the future.

      Incumbent exchange carriers pose a threat to our operations because
  they possess certain competitive advantages.

    In most of our markets, the primary competitor is the incumbent exchange
carrier, or its affiliate. Although the incumbent exchange carriers have
historically focused more heavily on local and long-distance voice services,
they are now focusing much more on providing data services for corporate users.
The incumbent exchange carriers generally have significant competitive
advantages, including:

  . significantly greater financial and other resources, including greater
    access to financing;

  . close ties with national regulatory authorities;

  . control over connections to local telephone lines;

  . ability to subsidize competitive services with revenues generated from
    services they provide on a monopoly basis; and

  . reluctance of regulators to adopt policies and grant regulatory approvals
    that will result in increased competition.

    In the future, the incumbent exchange carriers may devote substantially
more resources to the sale, marketing and provision of data and other services
that compete with us, which could have a material adverse effect on our
business, results of operations and financial condition.

      International telecommunications carriers have greater resources than
  we do.

    We expect to face competition from large international telecommunications
carriers, such as Telefonica, AT&T, Global One and MCI Worldcom, and from other
industry participants. While international telecommunications carriers have
focused on voice services, they may focus on the private telecommunications
network systems as deregulation of the telecommunications market continues. For
example, when the Argentine government permits full competition in long
distance voice, which is

                                       8
<PAGE>

expected in November 2000, these large telecommunications carriers may enter
the Argentine voice market and provide data transmission services as well. Many
of these potential competitors have substantially greater financial and other
resources than we do. In addition, consolidation of telecommunications
companies and the formation of strategic alliances within the
telecommunications industry could give rise to significant new competitors.
AT&T recently formed a new company, AT&T Latin America, by merging the
operations of a U.S. telecommunications company, FirstCom Corp., and Brazil-
based Netstream. AT&T Latin America has assets in Brazil, Colombia and Peru and
is expected to expand into Argentina through its acquisition of Keytech. To the
extent that new competitors enter our markets, it could have a material adverse
effect on our business.

  Other competitors have announced their intention to launch enhanced
  Internet services in our markets and their ability to establish a
  significant early presence could threaten our planned business.

    We expect to face substantial competition in providing enhanced Internet
services from various Internet service providers, particularly PSINet, a U.S.-
based global provider of Internet services to businesses. PSINet has acquired a
number of Internet service providers in Argentina, Brazil and Panama. Via
Net.Works, Inc. is another international provider of Internet access and
services with which we expect to compete in Argentina and Brazil. In addition,
we expect to face competition from incumbent exchange carriers, international
telecommunications providers and others in the market for enhanced Internet
services, such as Impsat and MetroRED. If PSINet or other providers are able to
establish a significant early presence before we can, it could have an adverse
effect on our ability to achieve and sustain significant enhanced Internet
service revenues.

We may incur substantial future debt obligations which may hinder our growth
and put us at a competitive disadvantage.

    We may need to incur significant additional debt in the future to fund our
business plan. As of December 31, 1999, we had approximately $15 million in
long-term debt outstanding, and we had an additional $386 million available
under our vendor financing agreements, assuming we can incur such debt in
compliance with the covenants set forth in these agreements. Incurrence of
substantial debt in the future could adversely affect our business and
operating results, including:

  . requiring us to use a substantial portion of our operating cash flow to
    pay interest, which reduces funds available to build out our local fixed
    wireless broadband access networks and to invest in Internet
    infrastructure and for other purposes;

  . placing us at a competitive disadvantage compared to our competitors that
    have less debt;

  . making us more vulnerable to economic and industry downturns and reducing
    our flexibility in responding to changing business and economic
    conditions;

  . limiting our ability to pursue business opportunities; and

  . limiting our ability to borrow more money for operations or capital in
    the future.

Our inability to effectively manage our growth could adversely affect our
business.

    Our future performance depends on our ability to develop our networks,
successfully invest in Internet infrastructure, implement our business strategy
and effectively manage our growth. Our planned

                                       9
<PAGE>

growth and expansion will place significant demands on our management and
operations. Our ability to manage this growth successfully will depend on:

  . expanding our management resources, network infrastructure, information
    and reporting systems and controls;

  . expanding, training and managing our employee base, including attracting
    and retaining skilled personnel;

  . evaluating new markets;

  . monitoring operations; and

  . controlling costs.

    If we are not successful in managing our growth effectively, our business,
financial condition and results of operations could be materially adversely
affected.

If we are unable to obtain and maintain the necessary building access rights or
enter into fiber agreements on favorable terms, it could adversely affect the
development of our local fixed wireless broadband access networks.

    Our ability to construct our local fixed wireless broadband access networks
and to offer our existing as well as planned services in each market depends
upon our success in securing building access rights. For each customer building
that we connect to our local network and for each hub that we construct, we
must obtain building access rights from the relevant building owner or
customer. If we are unable to successfully negotiate with building owners or if
negotiations become protracted, it would delay the development of our local
networks. In addition, for some of our connected buildings, we do not have a
lease agreement or other contractual right of access. If our building access
were challenged, it may have an adverse effect on our ability to provide
service to the affected customers.

    In addition, our ability to increase the capacity of our backbone within
each market depends in part on our ability to enter into third-party agreements
with fiber optic cable providers. If we are not able to enter into fiber lease
agreements or to purchase the fiber optic cable necessary to accommodate
expected increases in demand on favorable terms, our costs may increase or we
may not be able to meet anticipated demand for our services.

    Furthermore, our networks need clear lines of sight between our radio
transmitters and our receivers to provide the best service. We cannot assure
you that we will be able to obtain the necessary building access rights to the
most desirable buildings in our markets.

Our ability to offer enhanced Internet services on a large scale is subject to
numerous risks.

    Enhanced Internet services is a new area of business for us and is subject
to many substantial risks, including:

  . our ability to obtain vital interconnection, also known as peering,
    agreements with other communications providers;

  . our ability to obtain sites for construction of our Internet data
    centers;

  . our ability to build out the necessary facilities in a timely manner; and

  . our ability to develop service and support operations, including hiring
    and training employees and developing corporate standards and systems.

    If we are unable to enter into the necessary peering agreements, obtain
sites necessary to build data centers of sufficient size or develop service and
support operations, it could have a material adverse impact on our ability to
offer or develop our enhanced Internet business and operating results.
Moreover, we cannot assure you that we have identified all risks and accurately
estimated the costs associated with offering enhanced Internet services.

                                       10

    The success of our Web hosting services will depend in part on the level of
interest among business customers in Latin America in having their websites
hosted locally. If the demand for such service is less than we anticipate, it
could materially adversely affect our business.

    The installation of various planned undersea cables will increase Latin
American connectivity to Internet access points in the United States. This
could result in overcapacity which could in turn depress the prices we can
charge for our enhanced Internet services.

Our 10 largest customers account for a significant portion of our service fee
revenues and the loss of one or more of these customers could materially
adversely affect our business and results of operations.

    Because of our relatively short operating history, a significant portion of
our consolidated revenues has been derived from a small number of customers.
Our 10 largest customers accounted for 45% of our service fee revenues for the
year ended December 31, 1999. Telefonica de Argentina, our largest customer,
accounted for approximately 17% of our service fee revenues in 1999. The loss
of one or more of our 10 largest customers could materially adversely affect
our business and results of operations.

The non-exclusive nature of our national grant of spectrum in Brazil could
interrupt or threaten our ability to provide service in each of the major urban
markets we expect to serve in Brazil.

    Our national grant of spectrum in Brazil is non-exclusive and therefore may
require us to coordinate with competitors and other third parties regarding
access to the same spectrum frequencies, which could increase our costs of
doing business there and threaten our ability to provide service. To date, we
have encountered one instance in which another telecommunications provider in
Sao Paulo was granted access to an overlapping spectrum frequency. We resolved
the issue without interruption to our service, but we cannot assure you that in
the future there will not be other providers who are granted overlapping
frequencies or that such grants will not overcrowd the spectrum frequencies
that we use to provide broadband services.

We depend on our suppliers of switches, radios and other equipment and may
experience delays in receiving required components.

    We rely on other companies to supply key components of our local network
infrastructure, including data routing and switching equipment, radios,
operating and billing software and facilities construction. These components
are only available in the quantities and quality we require from limited
sources. We have already experienced some delays and may experience further
delays in receiving components or may not be able to obtain these components in
the amounts that we need or on a timely basis or at an affordable cost, or at
all. We also have experienced delays in the construction of our facilities due
to our suppliers.

We intend to pursue acquisitions of spectrum, services, technologies or
businesses, which could result in stockholder dilution and involve other risks.

    To implement our growth strategy, we intend to pursue acquisitions of
spectrum, services, technologies or businesses that are complementary to our
existing operations and our planned operations. Our ability to grow our
existing services and to introduce our planned enhanced Internet services will
depend in part on our ability to make certain acquisitions at prices and terms
that are attractive to us. Acquisitions involve many risks, including
difficulties in assimilating new operations, technologies, services and
products of acquired companies and diversion of management's attention from
other business concerns. We cannot assure you that we will successfully
consummate any acquisitions on acceptable terms, or at all.

    Any acquisitions we complete could result in dilutive issuances of equity
securities, incurrence of debt and contingent liabilities and increased
amortization expenses related to goodwill and other intangible assets.

Damage to our networks, system failure or design defects could result in a loss
of revenue and a loss of customers.

    Our success in marketing our services to business customers and other high
volume users will require that we provide a high level of reliability, capacity
and security via our network infrastructure. Our local networks will be subject
to possible physical damage (including from natural disasters), power loss,
capacity limitations, software defects and breaches of security (by computer
virus, break-ins or otherwise), all of which may cause interruptions in service
or reduced capacity for customers. In addition, any defects in the design of
our local network architecture may cause interruptions in service until
remedied. If any of these events occur, we may lose customers and market share,
which could harm our business and operating results.

If we fail to upgrade or replace our billing, customer service and information
systems as necessary or our systems do not operate as we expect, we will not be
able to conduct our business efficiently.

    Integrated and flexible management information and processing systems are
vital to our growth and our ability to monitor costs, process and provision
customer orders, bill and collect from customers and operate efficiently. We
are in the process of implementing new operating systems to integrate important
facets of our operations. For example, our current billing system is not
adequate to accommodate billing for usage-based services such as voice, which
we currently intend to offer beginning in 2001. We expect to install a new
billing system in 2001, which will enable us to bill for additional services,
including usage-based services such as voice. We cannot assure you that such
systems will be installed in time to launch voice services as currently planned
or that, upon installation, the systems will perform adequately or as expected.

    The development and implementation of our new systems relies in part on the
products and services of third-party vendors over which we have no control.
Unanticipated problems with our systems may harm our business and operating
results.

We will not be able to introduce voice services until we obtain the necessary
operating licenses and until we are able to secure the necessary
interconnection agreements with other telecommunications providers.

    We do not yet have operating licenses to provide voice services in many of
our markets, and we cannot assure you that we will be able to obtain such voice
operating licenses on acceptable terms or at all. In addition, our ability to
offer voice services in countries in which we do have operating licenses
depends on securing and maintaining interconnection agreements with other
providers, which agreements we currently do not have in place.


New competing technologies may pose a threat to our business.

    We cannot predict the effect on our business of technological changes, such
as changes relating to emerging wireline and wireless transmission technologies
and the use of the Internet for traditional voice, data or other broadband
services. Technological changes that render our equipment out of date, less
efficient or more expensive to operate than newer equipment could cause us to
incur substantial increases in capital expenditures to upgrade or replace such
equipment. We believe our future success will depend, in part, on our ability
to anticipate or adapt to such changes and to offer, on a timely basis,
services that meet customer demands. We rely on vendors with whom we have
financing agreements to anticipate and adapt to new technology and to make
products that incorporate such technology available to us. We

                                       12
<PAGE>

cannot assure you that we will obtain access to new technology on a timely
basis or on satisfactory terms. If we fail to obtain new technology it could
have a material adverse effect on our ability to complete successfully.

    New competing technologies may enhance the ability of competitors to
provide the same services that we offer and therefore adversely affect our
business. For example, new technologies such as digital subscriber line, or
DSL, can significantly enhance the speed of traditional copper lines. DSL or
other technologies could enable our incumbent exchange carrier competitors to
offer new high-speed services without incurring the expense of replacing their
existing copper networks. Widespread use of DSL in our markets could have a
material adverse effect on our ability to compete successfully.

Restrictions in our vendor financing agreements may constrain our ability to
operate our business as we desire.

    Each of our vendor financing agreements with Ericsson and Lucent contains
numerous conditions and limitations on the way in which we can operate our
business, including limitations on our ability to raise debt, sell or acquire
assets and pay dividends as well as various covenants that require us to
maintain specific financial ratios. These limitations may force us to pursue
less than optimal business strategies or forego business arrangements which
could have been financially advantageous to us and our shareholders. See
"Description of Our Financing Arrangements".

Our ability to compete in Latin American telecommunications markets is subject
to extensive regulation, which may be changed or administered in a manner
harmful to our business.

    We are subject to extensive regulation in each of the countries in which we
operate. In many of these countries, the opening of competition in the
telecommunications industry occurred only recently, and there is necessarily
some uncertainty as to how regulations and policies that affect our business
will develop. Changes in regulations governing matters such as interconnection
arrangements, capital investment, pricing and foreign ownership could have a
material adverse effect on our business and operations. Accordingly, we cannot
assure you that we will be able to provide our planned services in each of our
markets, and it is possible that regulations could be adopted that would
preclude us from offering some of the services that we expect to provide in the
future. In addition, the government of each of the countries in which we
operate imposes extensive licensing, installation, and build-out requirements,
many of which are difficult to comply with. We cannot assure you that we will
be able to meet these requirements, and our failure to do so could subject us
to the loss of licenses that are important to our business. Many of our
licenses are subject to renewal or expiration, and we cannot assure you that
our licenses will be renewed or that we will be able to obtain new licenses on
favorable terms or at all when our current licenses expire. In addition, we
expect competition for radio spectrum licenses to be strong and if we are
unable to obtain licenses in the future, our ability to expand our business may
be materially adversely affected. Finally, our dependence on licenses and
permits subjects us to the risk that administrative delays could have a
substantial adverse impact on our business and operations.

    Moreover, the government of any of the countries in which we operate may
impose new fees or increase the amount of fees relating to our spectrum grant
or operating licenses that could adversely affect our business, financial
condition and results of operations. For example, in December 1999, we received
notice from the Argentine telecommunications authorities that we will be
required to pay a usage fee which we expect to be no more than $1.4 million
with respect to our 10.5, 23 and 38 GHz spectrum frequencies. We believe that a
usage fee will be payable on an annual basis in the future.

                                       13
<PAGE>

    Our performance will depend, in part, upon how well we anticipate and adapt
to rapid regulatory changes occurring in the communications industry and
whether we are able to offer, on a timely basis, services that meet evolving
industry standards. The enactment of new adverse regulations or regulatory
requirements may increase our costs, which could have a harmful effect on us.
We cannot assure you that we will be able to adapt to these regulatory
developments or offer the necessary services on a timely basis or establish or
maintain a competitive position.

Our operations are subject to special economic and political risks throughout
Latin America.

    All of our operations are conducted in Latin America. Accordingly, we will
be subject to significant economic, political and social instability and other
risks not typical of investments in businesses conducted in the United States.
An investment in our common stock is subject to risks of doing business in
Latin America. Each country where we operate has experienced political and
economic instability in recent years. Moreover, as events in Latin America have
demonstrated, negative economic or political developments in one country in the
region can lead to or exacerbate economic or political crises elsewhere in the
region. In addition, events in recent years in other developing markets have
placed pressures on the stability of the currencies of a number of countries in
Latin America, including Argentina, Brazil and Colombia. Continued pressures on
the local currencies in the countries in which we operate are likely to have a
material adverse effect on many of our customers, which could in turn
materially adversely affect us. Volatility in regional currencies and capital
markets has also had an adverse effect on our ability and that of our customers
to gain access to the international capital markets for necessary financing and
refinancing. A lack of international capital sources for emerging market
borrowers could have a material adverse effect on us and many of our customers.
The imposition by the governments of the countries where we operate of capital
controls, exchange controls, or any other mechanisms that would restrict the
flow of funds from our local subsidiaries to us could significantly impair our
ability to honor our obligations under our vendor financing agreements.

    We do not expect fundamental improvements in macroeconomic conditions in
Latin America in the short term. We cannot assure you that economic
difficulties in Latin America will cease, including volatility in regional
currencies and capital markets, which would have a material adverse effect on
our business, results of operations and financial condition and the market
price of our common stock.

    Many of our targeted markets are in countries in which the rate of
inflation is significantly higher than that in the United States and which have
experienced significant volatility in currency exchange rates. We cannot assure
you that the effect of inflation on our operations in these countries can be
offset, in whole or in part, by corresponding price increases we impose, even
over the long term. Nor can we assure you that currency exchange rates will not
change in a way adverse to us or that currency controls will not be imposed.

    Argentina

    While we anticipate that our business outside Argentina will increase in
the coming years, Argentina is expected to remain our most significant market
in 2000 and, accordingly, developments in Argentina are of particular
importance to our future success.

    The instability and volatility in the world financial markets, which began
with the crisis in the markets of Southeast Asia in 1998 and spread to Russia
and Brazil, has negatively affected the Argentine economy and financial
markets. In addition to the effects of the economic difficulties experienced in
Brazil, Argentina's largest trading partner, in the first nine months of 1999,
Argentina experienced a decline in investor confidence as a result of domestic
political and economic developments. In October 1999, Moody's Investor Services
cut Argentina's long-term foreign currency rating to B1 from Ba3. The
International Monetary Fund recently provided Argentina with a three-year
credit facility amounting to $7.4 billion which is conditioned upon Argentina
achieving fiscal tightening and consistent structural

                                       14
<PAGE>

reforms. We are unable to predict the effects of these reforms on our business,
financial condition and results of operations or the market price of our common
stock. Additionally, Argentina's exchange-rate policy remains a major concern
and we cannot assure you that Argentine monetary authorities will be able to
support the existing parity of the Argentine peso and the U.S. dollar.

    Brazil

    Brazil is our second largest market in terms of revenues generated and we
fully expect that Brazil will become our largest market. Throughout the 1980s
and into the 1990s, the Brazilian economy has suffered from periods of
extremely high rates of inflation and recession. Historically, Brazil's
currency has frequently depreciated in relation to the U.S. dollar. At the end
of 1998, foreign exchange reserves in Brazil had declined to $44.6 billion from
nearly $67.3 billion at the end of August 1998. As of January 2000, Brazil had
exchange reserves of approximately $37.56 billion. These capital outflows,
which resulted from the Russian economic crisis (and the subsequent impact on
risk perception of investments in emerging market countries in general) and
high rates of inflation prevailing in the Brazilian economy, put pressure on
the Brazilian real. The Brazilian government permitted the Real to float freely
against the U.S. dollar in January 1999. Since that time, the Real has devalued
to a low of R$2.17 = $1.00 on March 3, 1999. At March 17, 2000, the Real traded
at a rate of R$1.74 = $1.00. We cannot assure you 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. A continued downturn in Brazil's
economy could further affect other Latin American countries through the loss of
investor confidence and shocks to intra-regional trade.

    Rapid changes in Brazilian political and economic conditions require us to
continually assess the risks associated with our operations in Brazil and
adjust our business and operating strategy. Although the Brazilian government
has indicated that it is committed to solving the economic crisis caused by the
devaluation of the Brazilian real, it will have to overcome internal political
resistance to austerity measures if the economic recession worsens and
unemployment figures rise. Economic forecasts suggest that the Brazilian
economy could suffer a recession in the future as economic austerity measures
and high interest rates depress consumption and investments. Brazil's large
financing needs remain a risk to stability and could cause material adverse
effects on our business, results of operations and financial condition or the
price of our common stock.

    Colombia

    We have recently launched operations in Bogota, and Colombia currently
represents our third largest market in terms of revenues generated. Colombia is
experiencing an economic recession, with unemployment over 20%. The Colombian
economy began experiencing a severe economic crisis in 1998. A combination of
low international commodity prices, a decline in global lending to emerging
markets, a decrease in domestic consumption and high interest rates have
resulted in an economic recession and a negative economic performance.
Preliminary figures indicate that the Colombian economy contracted in 1999 and
that Colombia's gross domestic product fell by 5% through the end of 1999. In
June 1999, Colombia's central bank effectively devalued the Colombian peso by
9% by widening the foreign exchange band for the peso, and in September 1999,
the central bank discontinued the use of the foreign exchange band and
permitted the peso to float freely against the U.S. dollar. In the third
quarter of 1999, citing Colombia's macroeconomic imbalances and rising levels
of government debt, Moody's Investors Services and Standard & Poor's downgraded
the country's credit rating to below "investment grade." In addition to
increasing borrowing costs for Colombian companies, the impairment of
Colombia's credit rating lowered investor confidence in that country and
compounded its economic difficulties.

    Colombia has experienced periods of violence over the past four decades,
primarily from leftist guerrilla groups, right wing paramilitary groups and
drug trade. Despite the promise of peace negotiations between the Colombian
government and the main left-wing guerilla group, known as the FARC,
hostilities between the parties have continued. These hostilities led the
Colombian government to cede effective control of certain portions of the
country to guerilla forces, order a curfew in certain regions of the country
and place the military on a heightened state of alert. We cannot assure you
that these

                                       15
<PAGE>

matters, individually or cumulatively, will not materially adversely affect our
business, results of operations and financial condition and the market price of
our common stock.

    Peru

    After having grown at an annual rate of 7.3% from 1993 through 1997, the
Peruvian economy was hit in 1998 by the wave of international financial crises
and the El Nino phenomenon. This slowed the previous level of growth
considerably. The international economic instability led to a severe liquidity
crisis in the Peruvian financial system, a speculative attack against the
currency and the contraction of credit to the private sector. However, economic
forecasts indicate the economy will continue to grow in the next few years,
though at a lower rate than during the period from 1993 to 1997. During 1999 the
economy expanded by only an estimated 3%, inhibited by tight liquidity and high
interest rates. We cannot assure you that future fluctuation in the world market
will not negatively affect the Peruvian economy, or that the annual growth rate
will return to previous rates.

    Panama

    Following more than two decades of political and economic instability,
since 1994 a democratically elected government has implemented economic policy
reforms to restructure debt, liberalize the trade regime, privatize state-owned
enterprises, lower tariffs and attract foreign investment. Nonetheless,
Standard & Poor's has rated the outlook for local currency and foreign currency
as negative. Moreover, in the wake of the withdrawal by the United States from
its military facilities and control of the Panama Canal, there is some
uncertainty concerning the Panamanian government's ability to attract foreign
investment and manage the vast properties received upon the United States'
withdrawal. Accordingly, we cannot assure you that economic reform will
continue and that uncertainties will not materially adversely affect investor
confidence and financial markets, which could harm our business and financial
condition.

    Uruguay

    Uruguay has strong economic ties to Brazil and Argentina. The February 1999
Brazilian currency devaluation reduced the rate of growth of loans and deposits
in Uruguay. As a result, the Uruguayan economy went through a slump that caused
the unemployment rate to rise above 10%. We cannot assure you that Uruguay's
economy will not be materially adversely affected by continuing economic
instability in Brazil and Argentina, which could harm our business and
financial condition.

We are vulnerable to currency fluctuations, devaluations and restrictions that
may increase our losses and cause fluctuations in our operating results.

    We are exposed to changes in foreign exchange rates because certain of our
revenues and costs are denominated in foreign currencies while a significant
portion of our liabilities are and will continue to be denominated in U.S.
dollars. To date, we have not adopted any hedging strategies to manage our
exposure to foreign currency exchange risk. Our exposure to exchange rate
fluctuations that could negatively affect our business, results of operations,
and common stock price is particularly significant in Brazil. Under Brazilian
law, our contracts with customers cannot be linked to the exchange rate between
the Brazilian real and the U.S. dollar, and we anticipate that a significant
portion of our future growth in sales will come from Brazilian markets. More
generally, our results of operations and business prospects are influenced by
the overall financial and economic conditions in Latin America. Many of the
countries in which we operate have experienced political and economic
volatility in recent years, and each of those countries has experienced some
level of economic contraction and financial difficulties during 1999. We cannot
predict whether prevailing economic conditions in Latin America will improve or
worsen, or what effect these conditions will have on the countries in which we
operate or upon our business.

Labor regulations and strong labor unions in Latin American markets could
increase our expenses.

    In general, labor regulations in Latin America are more favorable to
employees than in the United States. Most Latin American countries also require
higher rates of mandatory social security and similar contributions by
employers than the United States. In addition, labor unions in most Latin
American

                                       16


<PAGE>

countries are considered to be strong and influential. Our employees in Brazil
are currently unionized. Although we have not experienced any strikes in Brazil
yet and none of our operations are currently unionized in any other countries,
we may experience strikes or other significant types of conflicts with labor
unions or our personnel.

Departure of key personnel could harm our business.

    Our business is managed by a small number of key executive officers and
operating personnel. The loss of services of one or more of our key executives
could harm our business and our prospects.

    Further, we believe that our success will depend, in large part, on our
ability to attract and retain skilled and qualified personnel with experience
in each area of our business, including hiring new personnel to operate our
enhanced Internet services business. In particular, our ability to recruit
personnel throughout Latin America, especially for our planned offering of
enhanced Internet services, may be constrained by the relatively small pool of
talent available. If we are unable to recruit the necessary personnel, it could
harm our business and operating results.

We depend on payments from our subsidiaries to pay our obligations.

    We are a holding company, which means that we conduct all of our operations
and derive all of our operating income from our subsidiaries. Our ability to
pay our obligations in the future depends on receiving dividends and other
payments from our subsidiaries, raising additional funds in public or private
debt or equity offerings or selling assets. Our subsidiaries constitute
separate legal entities and their ability to pay dividends or make other
payments or advances to us will depend on their operating results and the
requirements of applicable law.

We are currently restricted from paying dividends and we do not plan to pay
dividends in the foreseeable future.

    We have never declared or paid any cash dividends on our capital stock and
do not anticipate paying cash dividends in the foreseeable future. See
"Dividend Policy." Moreover, our ability to pay dividends is limited by the
terms of our vendor financing agreements with Ericsson and Lucent. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Financial Resources."

Shares of our common stock becoming available for sale could materially
adversely affect the market price of our common stock and may impair our
ability to raise capital through the sale of additional stock.

    The    shares sold in this offering will generally be freely tradable
without restriction. We will have 51,394,331 shares of our common stock
outstanding upon completion of this offering that will be "restricted
securities" as that term is defined in Rule 144 under the Securities Act.
Stockholders holding 50,703,198 shares of our common stock will be entitled to
registration rights.

    Immediately after this offering, we also will have an additional 4,618,804
shares of common stock that are the subject of options and warrants.


                                       17
<PAGE>

    Our directors, officers, the most senior employee of each operating
subsidiary and most of our stockholders have executed lock-up agreements that
limit their ability to sell such common stock. These stockholders have agreed
not to sell or otherwise dispose of any shares of our common stock for a period
of at least 180 days after the date of this prospectus without the prior
written approval of Goldman, Sachs & Co. When the lock-up agreements expire,
these shares and the shares underlying the options will become eligible for
sale, in some cases subject to the volume, manner of sale and notice
requirements of Rule 144. The availability of these shares may depress the
market price of our common stock. See "Shares Eligible for Future Sale."

There is no prior public market for our common stock, the price of shares of
our common stock may be volatile and we cannot assure you that our share price
will not decline after this offering.

    Prior to this offering, there has not been a public market for our common
stock, and an active public market for our common stock may not develop or be
sustained after this offering. The initial public offering price for our common
stock will be determined by negotiations between us and the representatives of
the underwriters and may not be indicative of prices that will prevail in the
trading market. Moreover, the market price of our common stock could be subject
to significant fluctuation after this offering. Some of the factors that could
materially adversely affect our share price include:

  . quarterly variations in our operating results;

  . changes in revenue or earnings estimates or publication of research
    reports by analysts;

  . strategic decisions by us or our competitors, such as changes in business
    strategy, acquisitions or restructurings;

  . actions by institutional stockholders;

  . speculation in the press or investment community;

  . general market conditions; and

  . economic factors unrelated to our performance.

    Recently, stock markets in the United States have experienced significant
price and volume fluctuations and the market prices of securities of
telecommunications service providers and technology companies, particularly
Internet-related companies, have been highly volatile. Investors may not be
able to resell their shares of common stock at or above the initial public
offering price. In the past, periods of volatility in the marketplace for a
company's securities often have been followed by the initiation of securities
class action litigation in the United States against that company. The
institution of such litigation against us could result in substantial costs and
a diversion of our management's attention and resources, which could materially
adversely affect our business and financial condition.

If you purchase shares of our common stock in this offering, you will
experience immediate and substantial dilution.

    The initial public offering price of our common stock is substantially
higher than the book value per share of the outstanding common stock.
Accordingly, if you purchase shares of common stock in this offering, you will
experience immediate dilution of approximately $   in the book value per share
of common stock. This means that the net tangible book value of each share
purchased by you will be less than the purchase price you paid. Moreover, to
the extent that outstanding options to purchase our common stock are exercised,
or options reserved for issuance are issued and exercised, each person
purchasing common stock in this offering will experience further substantial
dilution.

Unauthorized actions of our local representatives or agents could subject us to
liability under the Foreign Corrupt Practices Act.

    We are subject to the Foreign Corrupt Practices Act, which generally
prohibits U.S. companies and their intermediaries from bribing foreign
officials for the purpose of obtaining or keeping business. We have enacted and
adhere to a Foreign Corrupt Practices Program, and we have taken precautions and
instituted a number of procedures to comply with the FCPA. However, we cannot
assure you that such precautions will protect us against liability under the
FCPA. In particular we may be held responsible for actions taken by our local
representatives or agents, regardless of our ability actually to control them.
Any determination that we have violated the FCPA could have a material adverse
effect on our business and operations.

                           FORWARD-LOOKING STATEMENTS

    Some of the statements in this prospectus are forward-looking statements.
These statements involve known and unknown risks, uncertainties and other
factors which may cause our actual results, performance or achievements to be
materially different from any future results, performance or achievements
expressed or implied by the forward-looking statements. Forward-looking
statements include but are not limited to:

  . our expectations and estimates as to completion dates, construction costs
    and subsequent maintenance and growth of the local fixed wireless
    broadband access networks we plan to build;
  . our ability to implement successfully our operating strategy and to sell
    capacity on our planned local fixed wireless broadband access network;
    and
  . future financial performance, including growth in sales and income.

    The following factors, among others, could cause our actual results to
differ materially from those expressed in any forward-looking statements we
make:

  . the rate of expansion of our network and/or customer base;
  . inaccuracies in our forecasts of customer or market demand;
  . loss of a customer that provides us with significant revenues;
  . highly competitive market conditions;
  . changes in or developments under laws, regulations and licensing
    requirements;
  . changes in telecommunications technology;
  . currency fluctuations; and
  . changes in economic conditions in the Latin American countries where we
    operate.

    These factors should not be construed as exhaustive. We will not update or
revise any forward-looking statements.

                           MARKET DATA AND FORECASTS

    This prospectus includes statistical data and forecasts concerning the
telecommunications industry that we obtained from industry publications. These
publications generally indicate that they have obtained information from
sources that they believe are reliable, but that they do not guarantee the
accuracy and completeness of the information. In particular, we do not know
what rates of general economic growth in the countries in which we operate were
assumed in preparing forecasts. Forecasts of developing industries, such as
ours, are not based upon sophisticated analysis of a substantial amount of
historical data as is the case for more mature industries. Often, interviews
with corporate leaders in developing industries, such as ours, form the basis
for much statistical data and forecasts. Thus, statistical data and forecasts
for developing industries, such as ours, are much less likely to be accurate.
We also have not sought the consent of any of these sources to refer to their
data in this prospectus.

                                USE OF PROCEEDS

    We will receive net proceeds from this offering of approximately $
million. If the over-allotment option granted to the underwriters is exercised
in full we will receive approximately $   million. This assumes that our common
stock is offered at $    per share, the midpoint of the range set forth on the
cover page of this prospectus, and is after deducting underwriting discounts
and commissions and the estimated expenses of this offering. We intend to use
the net proceeds to make capital expenditures for the build out of our local
fixed wireless broadband access networks, for our investment in Internet
infrastructure, for potential acquisitions and for working capital and general
corporate purposes, including to fund losses. We have not yet determined the
specific allocation of amounts of the proceeds among the purposes described. As
a result, our management will have significant discretion in applying the net
proceeds of this offering. Pending such application, we will invest the net
proceeds in short-term U.S. dollar denominated liquid securities.

    Consistent with our business strategy, we continually consider acquisition
opportunities that will enhance our business. As of the date of this
prospectus, we have no understandings, commitments or agreements with respect
to any material acquisitions other than those described in this prospectus.

                                    DILUTION

    As of December 31, 1999, our pro forma net tangible book value, after
giving effect to (i) the issuance of $127 million in private equity capital in
March 2000 net of approximately $1.3 million in equity issuance costs, (ii) a
proposed 7 to 1 reverse stock split expected to occur prior to the closing of
this offering, and (iii) the automatic conversion of all shares of preferred
stock outstanding immediately prior to this offering into 47,953,475 shares of
our common stock upon this offering, was $220.5 million, or $4.40 per share of
common stock. Net tangible book value per share represents the amount of our
total tangible assets reduced by the amount of our total liabilities, divided
by the number of shares of common stock outstanding. As of December 31, 1999,
our pro forma net tangible book value, as adjusted for the sale of shares in
this offering at an assumed initial public offering price of $   per share (the
midpoint of the range indicated on the cover of this prospectus), after
deducting the estimated underwriting discounts and commissions and other
expenses, and assuming no exercise of the underwriter's over-allotment option,
would have been approximately $   per share of common stock. This represents an
immediate increase of $   per share to existing stockholders and an immediate
dilution of $   per share to new investors. The following table illustrates
this per share dilution:

    The following table summarizes, as of December 31, 1999, after giving
effect to the automatic conversion of all shares of preferred stock outstanding
immediately prior to this offering into 47,953,475 shares of our common stock
upon the closing of this offering, a proposed 7 to 1 reverse stock split and to
the issuance of $127 million in private equity capital net of approximately
$1.3 million in equity issuance costs in March 2000, the total consideration

</TABLE>

    If the underwriters' over-allotment option is exercised in full:

  . the number of shares of common stock held by the existing stockholders
    would be reduced to    % of the total number of shares of common stock to
    be outstanding after this offering

  .  the number of shares of common stock held by new investors would be
     increased to     or    % of the total number of shares of common stock
     to be outstanding after this offering

    The tables above exclude as of December 31, 1999, (1) 2,800,544 shares of
common stock subject to outstanding options and (2) 368,723 shares of common
stock that may be issued should holders of certain preferred stock warrants
elect to exercise their warrants prior to the consummation of this offering.

                                       22

Upon consummation of this offering, there will be 576,355 shares of common
stock subject to additional outstanding stock purchase warrants. To the extent
outstanding options and warrants are exercised, there will be further dilution
to new investors. See "Capitalization," "Management--Executive Compensation"
and "Management--1996 and 1999 Stock Option Plans."

                                DIVIDEND POLICY

    We have not paid any cash dividends on our common stock and we do not
intend to pay cash dividends in the foreseeable future. We plan to retain
earnings, if any, for use in the operation of our business and to fund future
growth. In addition, our vendor financing agreements currently severely
restrict the payment of dividends on our common stock. See "Description of Our
Financing Arrangements."

    The following table shows our cash and cash equivalents and short-term
investments, and total capitalization as of December 31, 1999:

  . on an historical basis;

  . on a pro forma basis to give effect to (i) the issuance of $127 million
    in private equity capital in March 2000, net of approximately $1.3
    million in equity issuance costs, (ii) the automatic conversion of all
    shares of our preferred stock outstanding immediately prior to this
    offering into 47,953,475 shares of our common stock and (iii) a proposed
    7 to 1 reverse stock split expected to occur prior to the closing of this
    offering; and

  . on a pro forma as adjusted basis to give effect to the issuance and sale
    of    shares of common stock in this offering.


    This table should be read in conjunction with our audited consolidated
financial statements and the notes to the financial statements beginning on
page F-1. Our pro forma as adjusted capitalization assumes no exercise of the
underwriters' over-allotment option.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

    We seek to become a leading facilities-based provider of broadband
Internet, data and voice services in the major urban markets throughout Latin
America. Through local fixed wireless access networks which we own and operate,
we currently provide broadband data transport and dedicated Internet access to
large and medium-sized businesses, telecommunications carriers, Internet
service providers, Internet content providers, e-commerce providers and systems
integrators.

    From our inception to June 1998, our primary focus was to acquire spectrum
and operating licenses in Argentina, Brazil and Colombia. Since that time, we
have continued to obtain spectrum and operating licenses in these countries as
well as in Panama, Peru and Uruguay. In June 1998, we began constructing
substantial portions of our initial local network in Buenos Aires and in June
1999 we began constructing our local networks in Sao Paulo and Bogota.

    We launched commercial operations and sales in our first market, Buenos
Aires, in March 1999. From March to December 1999, we expanded our sales and
marketing force and continued to expand our local network in Buenos Aires. We
subsequently launched operations in Sao Paulo in December 1999 and Bogota in
March 2000.

    In March 2000, we made a strategic decision to enter the market for
enhanced Internet services. Concurrently with the build out of our local
networks, we are investing substantially in Internet infrastructure to enable
us to provide enhanced Internet services. We expect to use a substantial
portion of the proceeds of this offering to fund our investment as well as our
operating losses related to the build out of our local fixed wireless broadband
access networks and our investment in Internet infrastructure.

    To support our plan to build out local fixed wireless broadband access
networks in major urban markets in Latin America, we have raised $273 million
in private equity capital from our inception to March 31, 2000. In addition, we
entered into strategic supply and credit agreements with Ericsson and Lucent in
June and November 1999, respectively, which currently provide for, among other
things, $400 million of financing for equipment, services and related items.

    We currently expect to complete the initial build out of our local
broadband access networks and to launch operations in Rio de Janeiro, Belo
Horizonte, Lima and Panama City by the end of 2000. In Buenos Aires, Sao Paulo
and Bogota, we are expanding our networks to enhance the services we presently
provide and to expand the geographical coverage area of those networks. We are
expanding the capacity of the backbone of our networks by either purchasing
additional fixed wireless links or by building or leasing high capacity fiber
optic cable. As part of our investment in Internet infrastructure, we also
expect to obtain significant backhaul capabilities through leases or
indefeasible rights of use, commonly referred to as IRUs, of undersea fiber
optic and/or satellite capacity.

    We plan to offer voice services in Argentina and Peru beginning in 2001 and
we intend to offer voice services in each of our other markets in Latin America
as these markets are deregulated and we obtain the necessary operating
licenses. In order to offer usage-based services such as voice, we are
implementing new operating and business support systems and expect to invest
approximately $10 million in 2000 for such systems.

Revenues and Expenses

    Revenues

    We provide services to customers under contracts that typically range from
one to three years. The customer generally pays an installation charge at the
beginning of the contract and a fixed monthly fee based on the speed of the
circuit and type of equipment installed. Services, other than installation
fees,

                                       27
<PAGE>

are billed on a flat monthly rate. We recognize installation fees when the
installation is complete and accepted by the customer. We recognize monthly
fees in the month in which the services are provided. We report revenues net of
deductions for sales taxes.

    We have experienced pricing declines in Argentina during our first year of
operations, and we anticipate that we will experience pricing declines as
competition increases in Argentina and each of the other markets where we
operate or intend to operate.

  Expenses

    Our expenses principally include:

  . Technical and operating

  . Sales and marketing

  . General and administrative

  . Salaries and benefits

  . Depreciation and amortization

    The principal items comprising technical and operating expenses are:

     . License and spectrum fees. These are fees we pay to maintain our
       rights under concessions in accordance with government regulations in
       the jurisdictions where we, or a company we acquired, were granted
       radio frequencies. These fees are usually based on the amount of
       spectrum granted or in use in a specific market. We expect these fees
       to increase in the future in Argentina, Brazil, Colombia, Panama and
       Peru as our networks, customer base and revenues increase.

     . Building access rental payments. Wireless transmission equipment
       requires the placement of equipment on the roof of a building and in
       some cases, the rental of interior space for housing electronics. As
       the market for building access rights becomes more competitive, we
       expect the cost of leasing roof and interior space to increase both
       for hubs and customer buildings.

     . Network maintenance. We employ our own engineers in addition to
       engaging outside engineering contracting firms to maintain our local
       fixed wireless broadband access networks in each market. As our
       networks expand, these costs will increase.

     . Capacity leasing costs. We incur operating expenses related to the
       leasing of bandwidth from third parties. While these costs have not
       been significant to date, we expect increases in these expenses as
       part of our investment in Internet infrastructure.

    The principal items comprising our sales and marketing expenses are:

     . Commissions. Our sales personnel are paid a fixed salary and monthly
       or quarterly commissions based on sales productivity.

     . Advertising and Public Relations. We advertise in major print media
       in each market where we have operations or intend to launch
       operations in the near future. We also advertise on the Internet.

    The principal items comprising general and administrative expenses are:

     . Professional services. These are fees for recruiting, accounting and
       legal costs.

     . Office rent. As of March 31, 2000, we had offices in Belo Horizonte,
       Bogota, Buenos Aires, Lima, Panama City, Rio de Janeiro, Sao Paulo,
       and Washington, D.C. (the corporate headquarters). We also maintain a
       small corporate satellite office in New York City.


                                       28
<PAGE>

    The principal items comprising salaries and benefits expenses include:

     . Salaries and hourly wages of all employees except for commissions of
       the sales force. The sales force commissions are classified as sales
       and marketing. We recently have experienced increased costs in hiring
       employees, and we anticipate that such costs will continue to
       increase in the near future. Our total number of employees increased
       from 70 as of December 31, 1998 to 309 as of December 31, 1999. We
       currently anticipate that our total number of employees will increase
       to approximately 800 by the end of 2000, and therefore we expect our
       salaries and benefits to increase substantially as we develop and
       expand our operations.

     . Government mandated bonuses and benefits. Several countries in which
       we operate have laws or regulations that mandate the payment of
       bonuses, vacation pay, an extra month's salary or other continuing
       employment benefit that we account for as those benefits accrue.

     . Discretionary bonuses and benefits.

    Between January and March 2000, we granted to certain employees options to
purchase 1,671,440 shares of common stock at exercise prices ranging between
$4.34 and $10.15 per share. In March 2000, we will record a deferred stock
compensation charge of $7,761,324 for the difference between the estimated fair
market value of our common stock and the exercise price of the options on the
grant date. Such amount will be amortized over the vesting term of the options.

    The principal items comprising depreciation and amortization expense
include:

  . Depreciation of network and office equipment and leasehold improvements.
    These assets are depreciated over their remaining useful lives after they
    are placed in service. We acquire and continue to acquire spectrum rights
    in the future through acquisitions of companies and directly through
    government grants.

  . Amortization of capitalized spectrum and license costs. These costs are
    amortized over the life of the license. As we obtain such rights, we will
    incur increased amortization expense.

  . Amortization of goodwill. We anticipate future acquisitions, which may
    result in goodwill, which will be amortized in future periods.

Results of Operations

  Year ended December 31, 1999 compared to year ended December 31, 1998

    Revenues. Revenues for the year ended December 31, 1999 were $1,143,000,
compared to $24,000 for the same period in 1998. The increase in revenues in
1999 was due to our launch of operations in Buenos Aires in March 1999 and in
Sao Paulo in December 1999 and revenues from some early test customers in
Bogota.

    The breakdown of our customers, revenues and number of circuits for 1999
and 1998 by country and service offering is as follows:

    Technical and operating expenses. Technical and operating expenses for the
year ended December 31, 1999 were $3,276,000, an increase of $2,584,000
compared to the same period in 1998. The increase in these expenses was due
primarily to:

  . An increase in spectrum and licensing fees that totaled $1,568,000 for
    the year ended December 31, 1999, compared to $343,000 for the year ended
    December 31, 1998. This increase was primarily due to increased spectrum-
    based fees in Argentina. We also incurred additional licensing fees and
    taxes on additional spectrum we obtained in Argentina, Peru and Panama in
    1999.

  . An increase in site rental expense for the year ended December 31, 1999
    was $592,000 compared to $82,000 for the year ended December 31, 1998.
    The increase was directly related to the number of leased hubs and
    customer buildings we added, as we expanded our local fixed wireless
    broadband access network in Buenos Aires. Also contributing to this
    increase was an expense incurred from leasing building access rights for
    our backbone sites in Belo Horizonte, Bogota, Lima, Rio de Janiero and
    Sao Paulo.

  . An increase in network maintenance for the year ended December 31, 1999
    was $200,000 compared to $1,000 for the year ended December 31, 1998.
    This increase was due to work that began after completing our network in
    Sao Paulo and continued maintenance costs for our network in Buenos
    Aires.

  . An increase in the costs of leasing capacity from other
    telecommunications providers to carry traffic from our network to the
    Internet backbone in the United States and elsewhere out of Latin
    America.

    Sales and marketing expenses. Sales and marketing expenses were $2,403,000
for the year ended December 31, 1999, an increase of $2,143,000 compared to the
same period in 1998. The increase in these expenses was due primarily to:

  . An increase in direct marketing expenses in Argentina, Brazil and
    Colombia.

  . An increase in advertising in support of our launch of operations in
    Buenos Aires and Sao Paulo in 1999. Also, we increased spending on the
    development of sales materials to support future region wide marketing
    efforts, including the development of our Web site.

  . Sales commissions paid to our sales representatives based on the growth
    of customer circuits in Buenos Aires and Sao Paulo.

    General and administrative expenses. General and administrative expenses
were $6,535,000 for the year ended December 31, 1999, an increase of $3,401,000
compared to the same period in 1998. The increased general and administrative
expenses reflect growth in our operations, including the development and
implementation of our networks. In particular the increase in these expenses
was due primarily to:

  . An increase in recruiting costs as we expanded our management team in
    Latin America and in the United States.

  . An increase in the size of office and network operations center space
    rented. We opened offices in Belo Horizonte, Bogota, Lima, Panama City,
    Rio de Janeiro and Sao Paulo, expanded the office space in the
    Washington, D.C. headquarters and expanded the office/network operations
    space in Buenos Aires.

  . An increase in accounting and legal costs as we grow our business.

                                       30
<PAGE>

    Salaries and benefits expenses. Salaries and benefits expenses were
$13,032,000 for the year ended December 31, 1999, an increase of $8,529,000
compared to the same period in 1998.

    The increase in salaries and benefits was due primarily to:

  . An increase in the number of employees, from 70 as of December 31,1998,
    to 309 as of December 31, 1999. These additional employees were added to
    support the development of our network and operating activities in
    Argentina, Colombia and Brazil. We also added employees to support
    capital formation and business development efforts at our corporate
    headquarters.

  . Increases in the salaries and benefits of our personnel to recruit
    personnel with the expertise we require. Despite significant rates of
    unemployment in some of the markets where we operate, we are facing tight
    labor markets for qualified employees with experience in the
    telecommunications and Internet industries.

    Depreciation and amortization expense. Depreciation and amortization
expense was $2,511,000 for the year ended December 31, 1999, an increase of
$2,135,000 from the same period in 1998. The increase is directly related to
depreciation for customer telecommunications equipment placed into service in
Buenos Aires since March 1999 and network equipment placed into service in Sao
Paulo in December 1999. We expect these expenses to increase in future periods
due to construction of our networks in several markets. During 1999 and 2000,
we completed certain acquisitions and expect to amortize goodwill in connection
with these acquisitions.

    Other income (expense), net. Other income (expense), net was $1,781,000 for
the year ended December 31, 1999, an increase of $1,671,000 from the same
period in 1998. The increase was primarily due to increased interest income
earned on our short-term investments and invested cash balances, partially
offset by increased interest expense incurred under our vendor financing
agreements and losses on foreign currency translation.

    Provision for income taxes. Provision for income taxes was $105,000 for the
year ended December 31, 1999, compared to $0 for the same period in 1998. The
tax for 1999 was incurred by our operations in Colombia due to the deferral of
start-up costs and recognition of inflation adjustment income under Colombian
tax regulations and a minimum income tax assessed in Argentina. Since inception
we have been incurring losses and expect to continue to accumulate losses for
the next several years. These operating losses could, with certain restrictions
produce a tax benefit in future years. We have reserved fully against the tax
benefit, as we are unsure as to our future ability to produce net taxable
income in time to utilize the net loss carry forwards.

    Year ended December 31, 1998 compared to year ended December 31, 1997

    Revenues. Revenues were $24,000 for the year ended December 31, 1998
compared to $0 for the year ended December 31, 1997. Revenues for the year
ended December 31, 1998 were derived from services provided to customers in
Buenos Aires, during the testing phase of the network.

    Technical and operating expenses. Technical and operating expenses were
$692,000 for the year ended December 31, 1998 compared to $0 for the year ended
December 31, 1997. The increase in these expenses was due primarily to:

  .  An increase in spectrum and licensing fees that totaled $343,000 for the
     year ended December 31, 1998 compared to $0 for the year ended December
     31, 1997. This increase was due to fees related to maintaining our
     spectrum grant in Colombia.

  .  An increase in travel fees that totaled $138,000 for the year ended
     December 31, 1998 compared to $0 for the year ended December 31, 1997.
     This increase was due to travel by the engineering staff as we were
     designing and building the initial network in Buenos Aires.

                                       31
<PAGE>

  .  An increase in site rentals that totaled $82,000 for the year ended
     December 31, 1998 compared to $0 for the year ended December 31, 1997.
     This increase was due to our renting roof-top and interior space to
     facilitate building the network backbone in Buenos Aires.

    Sales and marketing expenses. Sales and marketing expenses were $260,000
for the year ended December 31, 1998 compared to $0 for the year ended December
31, 1997. The increase was due to public relations expenditures to support our
brand awareness building efforts.

    General and administrative expenses. General and administrative expenses
were $3,134,000 for the year ended December 31, 1998 compared to $922,000 for
the year ended December 31, 1997. The increase in these expenses was due
primarily to:

  .  An increase in recruiting costs that totaled $563,000 for the year ended
     December 31, 1998 compared to $0 for the year ended December 31, 1997.
     The increase is a result of efforts to build the U.S. and Argentine
     management teams and technical staff.

  .  An increase in accounting and legal costs that totaled $1,062,000 for
     the year ended December 31, 1998 compared to $636,000 for the year ended
     December 31, 1997. The increase was a result of our increasing need for
     these services as we grow our business.

  .  An increase in travel costs that totaled $508,000 for the year ended
     December 31, 1998 compared to $100,000 for the year ended December 31,
     1997. The increase was related to travel by our employees in support of
     business development, spectrum and license development and fundraising
     efforts.

    Salaries and benefits expenses. Salaries and benefits expenses were
$4,503,000 for the year ended December 31, 1998 compared to $415,000 for the
year ended December 31, 1997. The increase was due to an increase in the number
of employees from 12 as of December 31, 1997 to 70 as of December 31, 1998.

    Depreciation and amortization expense. Depreciation and amortization
expense was $376,000 for the year ended December 31, 1998 compared to $3,000
for the year ended December 31, 1997. The increase in these expenses was
directly related to the amortization of the spectrum and license assets in
Argentina and Colombia, depreciation on office equipment and amortization of
leasehold improvements. There was no depreciation of network equipment during
the year ended December 31, 1998 or 1997 as network equipment was not in
service during those years.

    Other income (expense), net. Other income (expense), net was $110,000 for
the year ended December 31, 1998 compared to $(240,000) for the year ended
December 31, 1997. The increase was primarily due to increased interest income
earned on invested cash balances partially offset by increased interest expense
incurred under our related party notes payable and vendor financing agreements.

    Provision for income taxes. There was no provision for income taxes in the
years ended December 31, 1997 or 1998.

    The operating results for any quarter are not necessarily indicative of the
operating results for any future period.

    Our future revenues and results of operations may significantly fluctuate
due to a combination of factors, including:

  . growth and acceptance of the Internet in Latin America that will directly
    affect the demand for the services that we offer;

  . our ability to attract and retain customers;

  . our ability to expand our networks into new markets and within existing
    markets to cover larger geographical areas at a lower per link cost;

  . our ability to maintain the quality of our networks and keep them
    technologically up to date with the latest enhancements;

  . our ability to retain key personnel;

  . technical difficulties associated with the manufacturers of the equipment
    we use in our networks and their ability to deliver products and services
    on a timely basis; and

  . general economic and regulatory conditions in the markets where we
    operate or intend to operate throughout Latin America.

Liquidity and Capital Resources

   The telecommunications and Internet infrastructure business is capital
intensive. We have incurred significant operating and net losses and expect
that such losses will continue for the next several years as we develop, build
and operate our local fixed wireless broadband access networks and as we invest
in Internet infrastructure. Cash provided by our operations will not be
sufficient to cover these operating and net losses. As of December 31, 1999, we
had $82.3 million of cash and short-term investments and net working capital of
$73.5 million.

   Cash used in operating activities was $8.5 million in 1998 and $18.6 million
in 1999, an increase of $10.1 million that was primarily due to increased
technical and operating, sales and marketing, general and administrative, and
salaries and benefits expenses. We used cash for investing activities of $4.4
million in 1998 and $100.7 million in 1999. Investing activities were primarily
for property and equipment expenditures, purchases of short-term investments
and spectrum and operating license acquisitions.

   From our inception to March 31, 2000, we have raised $273 million in private
equity investments.

   In June 1999, our wholly-owned operating subsidiary, Diveo, Inc., entered
into a vendor financing agreement with Ericsson Credit AB to provide us with
$100 million in equipment financing which was amended in November 1999 to
provide us with a total of $300 million in equipment financing. In November
1999 Diveo, Inc. also entered into a vendor financing agreement with Lucent
Technologies, Inc. whereby they will provide us with $100 million in equipment
financing. As of March 31, 2000, we had borrowed $26.8 million under the vendor
financing agreements with Ericsson and Lucent.

   We are using the amounts available under these agreements to fund the design
and construction of our local fixed wireless broadband access networks in
Argentina, Brazil, Colombia, Peru, Panama and Uruguay. The vendor financing
agreements together are available in tranches of $250 million and $150 million.
The second tranche of $150 million is available beginning on January 1, 2001
provided that we have borrowed all of the first tranche of $250 million and we
are in compliance with all of the terms of the agreements, including covenants.
We must use any funds that we borrow under these agreements to pay for
equipment, services and other related expenditures for the build out of our
networks. In addition, each of the vendor financing agreements includes various
financial and other covenants and restrictions that limit our ability to, among
other things, pay dividends, incur additional indebtedness, dispose of assets
and effect merger and consolidation transactions. For a detailed description of
these agreements, see "Description of our Financing Agreements" beginning on
page 60.

   As of December 31, 1999, our commitments consisted of various lease and
equipment purchase commitments totalling $48 million through 2004. In addition,
on February 25, 2000 we entered into an agreement to acquire INEA Internet,
S.A. and we are obligated to pay $3.5 million as part of the purchase price in
connection with such acquisition. See notes 12 and 14 to our audited
consolidated financial statements.

   Capital expenditures were $2.8 million in 1998 and $28.7 million in 1999. We
made these capital expenditures for property and equipment, including software,
necessary to deploy local fixed wireless broadband access networks in our
initial markets.

   Based on our current plans, we expect that we will make aggregate capital
expenditures of approximately $185 million in 2000 and $125 million in 2001. We
believe that the proceeds from this offering, earlier private equity capital
financing and funds available to us under our vendor financing agreements will
be sufficient to fund our capital expenditures and operating losses through
2001.

   If our plans change, the assumptions supporting our business plan prove
wrong, we expand or accelerate our business plan or we complete acquisitions,
the sources of funds described above may not

                                       34
<PAGE>

be sufficient to fully fund our capital requirements. We may be required to
seek public or private equity or debt financings, capital or operating leases
and other financing arrangements. To the extent we are unable to obtain
sufficient funding, we may be required to limit the number of markets we enter
or reduce our level of investment within a particular market.

Quantitative and Qualitative Disclosures About Market Risk

  Foreign Currency Risk

    We are exposed to changes in currency exchange rates because certain of our
revenues and costs are denominated in foreign currencies, while a substantial
portion of our liabilities will be denominated in U.S. dollars. Although we
believe that our geographic diversification provides some protection against
economic downturns in any particular country, our results of operations and
business prospects are influenced by the overall financial and economic
conditions in Latin America. Many of the countries in which we operate have
experienced political and economic volatility in recent years. Each of the
countries in which we operate has experienced some level of economic
contraction and financial difficulties during 1999. We cannot predict whether
prevailing economic conditions in Latin America will improve or worsen, or what
effect these conditions will have on the countries in which we operate or upon
our business. As a result, our financial condition and results of operations
may be affected by changes in the value of the local currencies in which we
transact business.

    To date, we have not adopted any hedging strategies to manage our exposure
to foreign currency exchange rate risk. We will continue to evaluate whether to
adopt hedging strategies if a market develops to limit exposure to fluctuations
in the currencies of any of the countries in Latin America in which we operate.

    Except in Brazil, fees set forth in our customer contracts are generally
tied to the exchange rate between the local currency and the U.S. dollar or are
denominated in U.S. dollars directly. Under Brazilian law, our contracts with
customers in Brazil cannot be linked to the exchange rate between the Brazilian
real and the U.S. dollar. We anticipate that a significant portion of our
future growth in sales will come from Brazilian markets and therefore there is
significant exposure to exchange rate fluctuations that could negatively affect
our business, results of operations.

    Our excess cash balances in the United States are invested in high-grade,
short and medium term commercial paper, money market accounts with U.S. banking
institutions and U.S. government securities. We fund our Latin American
operations from the United States on a monthly basis, balancing the need for
timely payments of in-country payables with maintaining low cash balances in
any foreign country, thereby minimizing risk from currency devaluation.

    While we intend to take steps to minimize exchange rate risks to the extent
available, we cannot assure you that we will not be materially adversely
affected by variations in currency exchange rates.

  Interest Rate Sensitivity

    We have interest rate risk exposure related to funds we borrow under our
vendor financing agreements with Ericsson and Lucent. Interest is charged at
the London Interbank Overnight Rate (LIBOR) plus 5.75% and therefore our
repayment obligations will be subject to interest rate risk resulting from
future increases in LIBOR. We currently do not mitigate the risk of interest
rate movements through the use of interest rate swaps or other hedging
techniques, but we may choose to do so in the future.

                                    BUSINESS

Overview

    We seek to become a leading facilities-based provider of broadband
Internet, data and voice services in the major urban markets throughout Latin
America. Through local fixed wireless broadband access networks which we own
and operate, we currently provide broadband data transport and Internet access
services to large and medium-sized businesses, telecommunications carriers,
Internet service providers, Internet content providers, e-commerce providers
and systems integrators. We currently offer Web hosting services and are
investing substantially in Internet infrastructure to enable us to provide
advanced Web hosting, co-location, facilities-based Internet transport services
and other enhanced Internet services on a large scale. We also intend to
complement our broadband Internet and data offerings with voice services.

    We have obtained substantial regional and national grants of spectrum and
telecommunications operating licenses in Argentina, Brazil, Colombia, Panama,
Peru and Uruguay, covering a total population of more than 135 million people.
In addition, we have obtained voice operating licenses in Argentina and Peru.
We are currently in various stages of designing, building and operating local
fixed wireless broadband access networks in 16 major urban markets in those six
countries. We have launched service in Buenos Aires, Sao Paulo and Bogota. In
addition, we have obtained voice operating licenses in Argentina and Peru. At
December 31, 1999, we had 309 employees, 219 buildings on our networks and 102
customers with 1,516 dedicated data and Internet circuit equivalents in
service. The 102 customers in December 1999 represented an increase of 89 from
13 customers in March 1999. In addition, for the year ended December 31, 1999
we had revenues of $1,143,000, an increase of $1,119,000 from $24,000 for the
year ended December 31, 1998.

    We were incorporated as a Delaware corporation in October 1996 under the
name Diginet Americas, Inc., and in March 2000, we changed our name to Diveo
Broadband Networks, Inc. We are a holding company and operate our business
through direct and indirect wholly-owned subsidiaries. Our principal executive
offices are located at 3201 New Mexico Avenue, N.W., Suite 320, Washington,
D.C. 20016 and our telephone number is (202) 274-0040.

Recent Developments

    On March 29, 2000, we raised $127 million in private equity financing.
Investors in this financing included a new investor to the company, Texas
Pacific Group/Newbridge Latin America, as well as several of our existing
investors including Goldman Sachs Capital Partners, Booth American, Columbia
Management, Meritage Private Equity Fund, Norwest Venture Partners and
Rothschild. The completion of this financing brought our total funded equity
capital raised since inception to over $273 million.

    On February 25, 2000, we entered into an agreement to acquire INEA Internet
S.A., a company that offers Internet access and related services to businesses
in Buenos Aires. This acquisition increases our corporate dedicated Internet
access business in Buenos Aires by adding over 50 new corporate customers and
additional personnel with Internet experience. The total purchase price is
approximately $8 million, payable in a combination of cash, promissory notes
and shares of our common stock. The closing of the transaction is subject to,
among other things, obtaining regulatory approval. We expect that this
transaction will close in April 2000. INEA had revenues of $2.2 million for the
year ended December 31, 1999.

    On March 31, 2000, we entered into an agreement to acquire two companies
that hold certain spectrum and operating rights in Colombia and Peru from
VeloCom, Inc. for $8.25 million in cash. The acquisition of these companies
allows us to nearly double our holdings of 38 GHz spectrum in Colombia and
Peru. We expect that this transaction will close in April 2000.

    On March 23, 2000, we entered into an agreement with Thomson-CSF Systems
Argentina S.A. to acquire certain assets consisting of ongoing contracts to
provide primarily broadband access services in Buenos Aires to large and
medium-sized businesses for a purchase price of up to approximately $3 million
in cash. The closing of the transaction is subject to customary closing
conditions. We expect that this transaction will close in May 2000.

Market Opportunities in Latin America

    The data and Internet services markets are two of the fastest growing
segments of the Latin American telecommunications market. These markets are
being reshaped by the increasing demand for bandwidth among corporate
customers, including significant increases in Internet usage. An industry
report, commissioned by us and dated April 1999, estimates that in Buenos
Aires, Sao Paulo and Bogota, revenues for dedicated Internet access and
dedicated data access will grow in the aggregate at compounded annual rates of
77% and 73%, respectively from 1999 to 2004. Another industry report dated
August 1999 estimates that Web hosting and co-location services related revenue
in Argentina, Brazil and Colombia in the aggregate will grow at a compounded
annual rate of 58% from 1999 to 2004.

    Broadband Data

    The limited nature of existing infrastructure in Latin America and the
widespread effect of many years of underinvestment in the broadband data sector
have limited the ability of existing telecommunications providers in Latin
America to address the increasing need of business customers for connectivity
between local access networks (LANs). This need is the result of the growth in
demand for bandwidth intensive applications, such as graphic files, video
conferencing capability, multimedia applications and remote client services
offered by certain industries.

    Basic Internet Access and Enhanced Internet Services

    Industry reports indicate that, as businesses in Latin America increasingly
adopt the Internet as a business tool, the demand for basic Internet access as
well as enhanced Internet services will increase significantly. For example,
one industry report estimates that the number of business Web sites will
increase an average of 120% annually during the next five years. To meet this
anticipated demand, we plan to offer a full range of broadband data services
and enhanced Internet services to large and medium-sized businesses in each of
our markets.

    Introduction of Voice Services

    As markets for voice services in Latin America become deregulated, we
intend to capitalize on the opportunity to provide those services. We believe
that demand for voice services will increase as these markets are deregulated
and the prices charged by existing providers are reduced. Although incumbent
exchange carriers currently hold dominant positions in the market for voice
services, we believe that there will be an attractive opportunity to enter the
market and we intend to offer such services as soon as we are able to obtain
the necessary operating licenses.

    Our Primary Markets in Latin America

    We believe there is a significant opportunity to provide Internet, data and
voice services to large and medium-sized businesses in the major urban markets
in Latin America in which we operate or intend to operate. In particular, we
anticipate that our operations in Brazil and Argentina together will represent
a majority of our revenues in the foreseeable future.

    The table below sets forth total population covered by our national
operating licenses and total population covered by our regional and national
spectrum grants for 1999 for the countries indicated, according to industry
sources:

  Our Target Customers

    Our target customers are large and medium-sized businesses,
telecommunications carriers, Internet service providers, Internet content
providers, e-commerce providers and systems integrators. We believe these
customers generally have:

  . high current and future demand for our services;

  . high demand for additional services;

  . high average revenues;

  . low churn rates; and

  . low credit risk.

  Our Competitive Strengths

    We believe that we distinguish ourselves through several competitive
strengths, including:

    Pan regional presence and holdings. We are leveraging our substantial
holdings of broadband wireless spectrum and regional and national operating
licenses to establish an early presence in Latin America, particularly in
Brazil and Argentina. Our regional and national grants of spectrum cover a
total population of more than 135 million people throughout Latin America. We
have already launched operations in Sao Paulo, Buenos Aires and Bogota and plan
to launch operations in Rio de Janeiro, Belo Horizonte, Lima and Panama City by
the end of 2000. We have developed significant expertise in securing building
access rights and leases to key buildings in business districts in each of the
markets in which we operate.

    Fixed wireless broadband access technology. We primarily use fixed wireless
broadband access technology as a high quality alternative to existing copper
and fiber-based systems because it enables us to rapidly deploy our local
networks on a cost effective basis. In addition, employing fixed wireless
technology enables our capital expenditures to be success-based, meaning that
we do not incur significant capital expenditures until we have identified
sufficient customer demand. Moreover, we are able to reach customer buildings
in areas where it may not be cost-effective for other providers to lay fiber
optic cable.

    Flexible owned and operated networks. As a facilities-based provider, we
are able to control the quality, capacity and availability of our broadband
data, dedicated Internet access and enhanced Internet services.

    Focused sales, marketing and customer service. We have built and continue
to develop a targeted sales and marketing approach as well as proactive
customer service groups in each market.

    Proven management. We effectively combine the substantial experience that
our corporate management team has obtained in the competitive U.S.
telecommunications and Internet industry with the local knowledge, contacts and
expertise of our in-country management and sales forces. We believe the
quality, experience and teamwork of our management team will be critical
factors in the implementation of our growth strategy. Our corporate and local
management teams together have an average of approximately 20 years of
experience in the telecommunications and data industries. Our local sales
forces in each country are knowledgeable about their respective markets and
have enabled us to rapidly penetrate our markets and increase our customer
base.

    Strong investor and strategic vendor relationships. We have strong equity
investors, including Goldman Sachs Capital Partners, Alta Communications,
Norwest Equity Capital, Texas Pacific Group/Newbridge Latin America and
Rothschild, as well as strong strategic and financing relationships with
Ericsson and Lucent. Each of the Goldman Sachs, Alta, Norwest and Texas Pacific
Group/Newbridge Latin America investors has representation on our board of
directors. We believe that the presence of these investors and vendors provides
us with beneficial strategic advantages as we expand our market presence.

Business Strategy

    Our objective is to be a leading facilities-based provider of broadband
Internet, data and voice services in the major urban markets throughout Latin
America. Our strategy consists of the following key initiatives:

  Accelerate the development of current markets and the roll-out of
  additional markets by leveraging our substantial spectrum holdings,
  significant operating rights and experience in entering new markets.

    Demand for broadband data connectivity and Internet access is growing
quickly in Latin America. We are building out our local fixed wireless
broadband access networks in urban markets in Argentina, Brazil, Colombia,
Peru, Panama, and Uruguay. We believe the most attractive market opportunities
are in Brazil and Argentina, and we are focusing a majority of our investment
to build broadband infrastructure in these two countries. We intend to launch
operations in Rio de Janeiro, Belo Horizonte, Lima and Panama City by the end
of 2000. We intend to continue to apply for and obtain additional operating
licenses and spectrum in existing as well as additional markets.

  Lead with dedicated Internet access and dedicated broadband services and
  complement with staged introduction of voice services.

    We intend to focus on providing dedicated Internet and broadband data
services, which we believe will be the fastest growing segment of the
telecommunications services market in Latin America. Our primary services
currently include dedicated broadband access and dedicated Internet access. We
are investing substantially in Internet infrastructure in order to offer Web
hosting, co-location, facilities-based Internet transport services and other
enhanced Internet services. We have an operating license in Argentina that will
allow us to begin providing local voice services, as well as national and
international long distance voice services beginning in November 2000 and are
currently licensed in Peru to offer national and international long distance
voice services. We plan to offer such services in both countries beginning in
2001. As soon as we are able to obtain the necessary operating rights in each
of our other markets, we intend to add local and long distance voice services
as an additional product for existing customers.

  Expand our large and medium-sized business customer base through a focused
  direct sales force, third-party alliances and proactive customer service.


    We are directing our primary marketing efforts to capture large and medium-
sized business customers through a focused sales effort based on detailed
market research. Our approach and focus on corporate end users seeks to
establish a sustainable growing customer base through rapid service
installations, superior quality of connectivity, competitive pricing and
responsive customer service. As we expand our business customer base, we will
continue to provide high speed data transport and dedicated Internet access to
telecommunications carriers, Internet service providers, Internet content
providers, e-commerce providers and systems integrators.

  Invest substantially in Internet infrastructure to provide enhanced
  Internet services.

    We believe there is a significant opportunity to provide enhanced Internet
services and our goal is to establish an early presence in each of the markets
in which we operate or intend to operate. We are investing substantially in
Internet infrastructure to enable us to provide Web hosting, co-location,
facilities-based Internet transport service and other enhanced Internet
services. Our investments include constructing Internet data centers, securing
high quality national and international Internet connections and hiring
additional skilled personnel.

  Pursue strategic acquisitions, partnerships and joint ventures.

    We intend to continue to pursue acquisitions, partnerships and joint
ventures relating to companies, assets and technologies that complement our
current product offerings and enhance our business.

                                       39
<PAGE>

  Continue to attract, retain and motivate skilled personnel.

    We intend to continue to attract, retain and motivate skilled Latin
American and U.S. personnel by granting stock options to all employees.

    In most markets, we use the 23 to 38 GHz frequency range to connect
customers to our central hub sites. That frequency range provides for distances
from a hub of 1.5 to 5 kilometers, depending on such variables as topography,
rain and line of sight. The 23 to 38 GHz frequency range can typically carry
data at speeds ranging from 64 Kbps to 155 Mbps, suitable for the vast majority
of first mile customer requirements. We also use lower frequencies, 7 to 20
GHz, to interconnect our hub sites. Because of the characteristics of 7 to 20
GHz frequency range, our hubs can be placed at distances ranging from 2 to 30
kilometers from each other. This allows for capital efficiency by using fewer
hubs to cover a market or to provide coverage to an area of a city with many
potential customers such as an industrial park that is situated outside the
downtown area.

    We are deploying proven point-to-point technology to build out our local
fixed wireless broadband access networks. With this technology, each customer
building is connected to our local network through a dedicated, point-to-point,
two-way radio link that is set up between a pair of narrow-beam antennae
pointing at each other. This approach has been used for many years throughout
the world, and standardized equipment is currently widely available from a
variety of suppliers.

    Fixed wireless technology provides the following advantages:

    Rapid deployment. We install a radio on the roof of a customer building
with line of sight to another radio installed on one of our hubs. Unlike copper
or fiber-based systems, we do not have to dig up streets or string wires on
poles to establish connections to customers. Therefore, we can complete
installations and provide service more quickly than wireline service providers.

    Success-based capital expenditures. The amount and timing of capital
expenditures for the build-out of our local networks depends greatly upon
customer demand. Our initial costs to install the core network elements for a
market, including the hubs, service gateways and a network operations center is
approximately 25% of our expected total costs for a new market. After this
investment, we are able to initiate service in that market as we connect
customer buildings to our local network. We make the remaining 75% of our total
investment over time as customer demand drives our decision of when to purchase
and install the equipment necessary to connect a new customer building to our
local network.

    Lower build-out costs. We believe that our costs to launch service in a
market and to connect each customer are lower than for copper and fiber-based
network providers. Unlike copper and fiber-based providers that must install
and maintain a significant amount of wire and cable, our fixed wireless
technology does not require installation of wires and cable, except for minimal
amounts within customer buildings. Consequently, our installation and labor
costs are significantly lower compared to copper and fiber-based systems, and
we believe we can reach customer buildings more efficiently.

    We are also currently testing point-to-multipoint technology. This
technology enables the network side of the radio link to be connected through a
"multipoint transceiver" in which an antenna with a larger beam (typically 45
to 180 degrees) communicates with several customer buildings simultaneously.
Point-to-multipoint technology offers certain cost benefits in reaching
buildings with fewer customers as well as in less dense suburban areas. If it
proves to be commercially viable, we intend to employ such technology to
maximize the application of our network assets, reach more customers in
existing coverage areas and expand the reach of our local networks. However,
the success of our current business strategy does not depend on our ability to
implement point-to-multipoint technology.

  Network Architecture

   Set forth below is a representative diagram of our local fixed wireless
broadband access networks:

[Network Diagram]

   The architecture of our local networks consists of five critical parts:

   Building hubs. Our typical urban market initially will consist of 3 to 8
hubs, which are strategically located in high demand areas with good line-of-
sight characteristics and which we believe will cover between 50 to 80% of the
addressable large and medium-sized businesses that we have identified. Each
hub is constructed to provide access to an average of 30 customer buildings.

   Interconnecting the hubs. Initially, all hubs are interconnected within a
market to form the backbone of our network, using fixed wireless links that we
own, which can accommodate data traffic up to 622 Mbps. Hubs are
interconnected in a configuration with redundancy that is optimized according
to the characteristics of each urban market. As demand for service grows, we
will increase the capacity of our network backbone by adding additional fixed
wireless links or building or leasing fiber optic cable. We have recently
begun to deploy fiber to increase the capacity of the backbones in Buenos
Aires and Sao Paulo. We construct our local fixed wireless broadband access
networks using Asynchronous Transfer Mode (ATM) switching technology. This
technology supports true multi-protocol service networking, including Internet
protocol, digital private line, frame relay, ATM, voice and video all in the
same network backbone. This approach gives us the flexibility to rapidly
deploy new services on a cost-effective basis without disrupting services that
are already existing on our networks.

   Connecting customers to hubs. We deploy fixed wireless technology to
connect each customer building to a central hub with an average service radius
of approximately 1 to 2 kilometers. The hubs are strategically located in high
demand areas with good line-of-sight characteristics. Each customer building,
referred to as a tributary, has its own equipment, which consists of two major
components: (1) an integrated antenna/radio outdoor unit, which is installed
on the roof of the building or a nearby building and (2) the indoor customer
interface equipment, which is installed within the customer building. Based on
our experience to date, it requires an average of 21 days to connect a
customer building to a hub from the time an order is received. This process
includes (1) obtaining the building access rights, which typically

                                      41
<PAGE>

requires the most time, (2) installing the necessary equipment and (3)
establishing the connection to our network operations centers. Once we have
connected a customer building to a hub, it requires an average of five days to
connect an additional customer within that building.

    Network operations center. Our network operations centers are staffed to
provide real-time alarm, status and performance information 24 hours each day,
seven days each week, 365 days of the year. As of March 31, 2000, we had
network operations centers operating in Argentina, Brazil and Colombia and we
intend to add a center in Peru. The network operations centers in Argentina and
Colombia will also cover markets in Uruguay and Panama, respectively. We employ
network management systems at each center to assure consistent and reliable
performance. We also plan to build back-up facilities to further enhance our
network reliability.

    The service gateway, taking traffic from the first mile to points outside
our networks. Service gateway nodes are installed to act as interconnection
points to send traffic to destinations covered by other network service
providers, including Internet service providers, digital private line providers
and other data and voice service providers outside our network. Data routing
equipment and switches direct a data packet, digital private line or voice
signal from its origin to its correct destination according to its network
address technology or telephone number.

  Build-out of Local Networks

    We are currently in various stages of designing, building and operating our
local fixed wireless broadband access networks in 16 major urban markets
throughout Latin America. We have substantially built out local fixed wireless
broadband access networks and launched operations in Buenos Aires, Sao Paulo
and Bogota and plan to launch operations in Rio de Janeiro, Belo Horizonte,
Lima and Panama City by the end of 2000.

    The table below sets forth for each country the number of major urban
markets where we operate, the number of hubs built and the number of customer
buildings connected as of December 31, 1999:

Internet Infrastructure

    We are investing substantially in Internet infrastructure to enable us to
provide Web hosting, co-location, facilities-based Internet transport services
and other enhanced Internet services on a large scale. Our planned investment
includes:

    Construction of Internet Data Centers

    We plan to lease appropriate space within each market in which we intend to
offer enhanced Internet services in order to construct high quality Internet
data centers. The Internet data centers will contain the necessary
infrastructure support services and data equipment in order to offer enhanced
Internet services. We currently anticipate that our Internet data centers will
range in size from 10,000 square feet to 100,000 square feet and expect to have
operational Internet data centers in Argentina, Brazil, Colombia and south
Florida by the end of 2000. Each Internet data center will be designed with
back up power, be protected

                                       42
<PAGE>

against damage from natural hazards, and contain 24 hours a day, seven days per
week staffing and security. We also plan to establish new network operations
centers to support each Internet data center and to operate these network
operations centers on a 24 hours a day, seven days per week basis as well.

    Securing High Quality National and International Connectivity

    In order to offer enhanced Internet services, we must secure high quality
national and international connections to the Internet. We are obtaining
dedicated connections to Internet access points in the United States and within
the region from satellite providers and/or undersea fiber optic cable
providers. In addition, we expect to enter into local peering agreements with
other Internet service providers to directly connect our network with the major
Internet service providers within each country. The local peering agreements
will create several advantages, including enabling us to route Internet traffic
efficiently by avoiding the congestion created by the inefficient Latin
American infrastructure.

    Hiring Additional Personnel

    We are hiring additional personnel to manage and operate our Internet data
centers. Depending on the size of each data center, we anticipate hiring
between 30 and 60 additional personnel to operate and maintain each center. In
addition, we plan to hire a new sales and marketing force within each market
dedicated to sales and support of the enhanced Internet services offering.

    Set forth below is a diagram depicting our typical local fixed wireless
broadband access network, our planned Internet data center and Internet access
points:

[Internet data center Diagram]

Third-Party Agreements

  Real Estate Site Acquisition

    Identifying and securing sites is critical to our success. Upon entering a
new market, we immediately hire local site acquisition staff, who are
knowledgeable about local real estate, zoning, and commercial customs and
codes. To facilitate a rapid deployment, our site acquisition team may also
contract with a local firm that has experience working in the industry. We
enlist such local agents to identify, pre-qualify and negotiate with landlords
on our behalf.

    Our site acquisition process typically includes several phases. First, our
engineering staff together with our marketing team designates areas of a market
that represent significant potential customer demand. Our site acquisition team
identifies site candidates that meet certain criteria. Once we have identified
candidates for each search area, the site acquisition team performs a detailed
analysis of each candidate in accordance with these requirements and
subsequently begins negotiations with potential candidates. Prior to signing
any lease, the site acquisition team performs due diligence regarding building
access rights and the existence of any liens or lawsuits against the building
or management company. After signing a lease, our site acquisition team is
responsible for maintaining an ongoing relationship with landlords so that upon
the occurrence of lease renewals, renegotiations or cancellations, we will have
a positive relationship with all parties involved.

  Building Space Lease or Use Agreements

    As part of the build-out of our fixed wireless broadband access networks
and prior to providing service to customers, we obtain real property leases or
building access rights from building owners to lease or use a portion of the
roof and internal space of the building. We use the roof space to install our
radio towers, radios and other equipment and use interior space to house
equipment and drop connections from our roof towers to the customer premise.

    We use different forms of agreements for hubs and customer buildings. Our
hub site agreements are real property leases with at least a five-year term and
an option for us to extend for another five years, and often include the lease
of office space in the building to house our local offices or local network
operations. Our customer building agreements are generally for a shorter term
of three to five years and are either real property leases of specific roof top
space or use agreements that provide us with substantially similar rights.

    The costs to obtain building space for both hub, and customer buildings
generally are payable in local currency and provide us with building access 24
hours a day, 7 days a week, 365 days a year, utilities connections, and
covenants against line of sight interference by other rooftop users. Our
building space and use agreements may only be terminated by the building owner
upon certain limited events, such as nonpayment of rent, bankruptcy and
regulatory noncompliance. In some jurisdictions, monthly rent payments for
customer buildings are a function of revenues produced from sales to customers
in the building. Most of our building space lease and use agreements are non-
exclusive.

  Fiber Lease Agreements

    We recently have entered into two fiber optic cable lease agreements to
increase the capacity of the backbone of our local networks. In December 1999,
we entered into a fiber optic cable lease agreement to increase the capacity of
our network backbone in Buenos Aires and on December 30, 1999, we entered into
a fiber optic cable lease agreement to increase the capacity of our network
backbone in Sao Paulo. We will continue to decide on a market by market basis
whether to increase the capacity of the backbone of each of our local networks
either by entering into additional fiber lease agreements, building fiber or
through installing additional fixed wireless links that we will purchase.

  Supply Agreements

    Ericsson and Lucent Agreements. Through our operating subsidiary, Diveo,
Inc., we are party to five-year purchasing agreements with Ericsson Telecom AB
and Lucent Technologies World Services, Inc.

                                       44
<PAGE>

The agreements extend through June 2004 and November 2004, respectively. In
accordance with the framework established by our agreement with Ericsson,
country-specific purchasing agreements have been entered into between
respective Diveo and Ericsson subsidiaries in Argentina, Brazil, Colombia and
Panama, and such agreements may be set up between the parties' respective
subsidiaries in any other area of Latin America where we operate or intend to
operate. Our agreement with Lucent enables us to purchase equipment and
services in each of the markets in Latin America where we operate or intend to
operate.

    The Ericsson agreement provides that our subsidiaries may, in the
aggregate, purchase up to $300 million in products and services under the
various country-specific agreements. Under the Lucent agreement, we have a
commitment to purchase $25 million in products and services over the initial
five-year term. This commitment is subject to, among other things, a number of
terms, including the performance of Lucent and refinancing of the agreement.

    Products that may be purchased under the Ericsson and Lucent agreements
include:

  . transmission equipment

  . transport equipment

  . data switching equipment

  . access equipment

  . network management hardware and software

    Services that may be purchased under the agreements include:

  . project management              . training


  . microwave systems engineering   . operations support


  . professional consulting services. hardware repair


  . project engineering             . hardware field maintenance


  . site preparation                . software maintenance


  . site engineering and installation
                                    . comprehensive maintenance and management
                                      services

  . network integration and verification

    Available products and services under the Ericsson agreement include those
offered directly by Ericsson, third-party products and services offered on a
preferred basis through Ericsson, and, with some limitations, other third-party
products and services. Under the Lucent agreement, available products and
services include those offered directly by Lucent and third party products and
services offered through Lucent.

    Our agreements with Ericsson and Lucent (and each of the country-specific
agreements) contain detailed provisions governing performance, pricing, and
service levels and customary legal protections relating to representations and
warranties, indemnities, limitations of liability, and compliance with
applicable laws and regulations.

Our Services

    We currently provide the following services:

  Digital Dedicated Access

    We provide dedicated broadband access designed to provide high-speed,
reliable and secure transmissions. With this service companies can connect to
their subsidiaries, branch offices and clients to

                                       45
<PAGE>

exchange broadband data, voice or video with a high level of security and
reliability. We also provide this service to Internet service providers,
telecommunications carriers and systems integrators to permit them to provide
service to their end user customers.

  Dedicated Internet Access

    We provide dedicated Internet access service to large and medium-sized
businesses. These customers are able to receive always-on Internet access at
speeds ranging from 64 Kbps to 155 Mbps.

  Enhanced Internet Services

    Through the Internet data centers we are constructing, we will provide a
number of different enhanced Internet services that include Web hosting, co-
location services and facilities-based Internet transport services.

    Web hosting. We will offer both dedicated hosting and shared hosting
services in our Internet data centers. For dedicated hosting customers, we will
provide one or more servers to customers for their exclusive use. For shared
hosting customers, we will provide up to 150 customer websites on one server,
with each customer provided a portion of the space on that server. In both
cases these hosting servers will be owned and maintained by us and connected to
our facilities-based Internet backbone.

    Co-location. Under our co-location service, we will provide space for a
customer's Internet and telecommunications equipment in our Internet data
centers. This equipment will be connected to our facilities-based Internet
backbone. The service will include both space in the Internet data center as
well as specified amounts of bandwidth on our facilities-based Internet
backbone.

    Facilities-based Internet transport services. We will offer facilities-
based Internet transport services to customers that connect to our facilities
from other locations but may otherwise not be co-location or Web hosting
customers because their equipment is physically located in another location. We
expect to be able to offer services such as heightened levels of privacy and
security, as well as service level agreements whereby customers pay different
prices for different guaranteed levels of Internet service.

  Voice

    We expect to offer local and national and international long distance
services to corporate customers and resellers in each of our markets upon
obtaining voice operating licenses. We have an operating license in Argentina
that will allow us to begin providing local and long distance voice services
beginning in November 2000 and are currently licensed in Peru to offer national
and international voice services. We plan to offer such services in both
countries beginning in 2001. We intend to offer local and long distance voice
services in each of our remaining markets throughout Latin America as these
markets are deregulated and we obtain the necessary operating licenses. We
expect to offer voice services to existing customers as well as new customers
in existing customer buildings.

Customers

    We serve large and medium-sized businesses, telecommunications carriers,
Internet service providers, Internet content providers, e-commerce providers
and systems integrators. Since we commenced operations in early 1999, we have
increased our customer base from 13 in March 1999 to 102 in December 1999.
Because of our relatively short operating history, a significant portion of our
consolidated revenues has been derived from a small number of customers. In
addition, because we have operated primarily in Argentina and Brazil, a
significant number of our customers, including our largest customers, currently
are located in those two countries. Our 10 largest customers accounted for
approximately 45% of our service fee revenues in 1999. One customer alone
accounted for approximately 17% of our service fee revenues in 1999.


                                       46
<PAGE>

    Corporate Customers

    We focus on offering high quality services to large and medium-sized
businesses because we believe this segment offers the most significant
opportunities in our markets. Generally, we believe these companies have the
largest underserved demand for data services and high-speed dedicated Internet
access. As of December 31, 1999, we had 66 corporate customers.

    Telecommunications Carriers

    We provide local broadband services to other telecommunications carriers,
including the incumbent telecommunications services providers in our markets.
By providing service to carriers, we are able to add new buildings by using
such carriers as anchor customers. As of December 31, 1999, we provided service
to 18 telecommunications carriers.

    Internet Service Providers

    We offer dedicated Internet access to Internet service providers so that
their customers can access the Internet through our networks. As of December
31, 1999, we provided services to nine Internet service providers.

    Internet Content Providers and E-Commerce Providers

    We are currently expanding our offerings for Internet content providers and
e-commerce providers to include Web hosting and co-location services, mirroring
and cacheing services and Internet transport services to facilitate and enhance
the performance of their product offerings.

    Systems Integrators

    We provide local broadband services to systems integrators to enable them
to offer a complete solution to their customers. As of December 31, 1999, we
provided services to nine systems integrators.

    Customer Contracts

    Contracts with our customers typically range in duration from one to three
years. To reduce churn, we impose penalties for early termination of customer
contracts. Our customers generally pay a one-time installation fee and a fixed,
monthly fee for service.

    Except in Brazil, our contracts generally provide for payment in U.S.
dollars where permitted or for payment in local currency linked to the exchange
rate at the time of invoicing between the local currency and the U.S. dollar.
The revenues of our customers are generally denominated in local currencies.
Although our customers include some of the largest and financially sound
institutions in each country, devaluation of local currencies relative to the
U.S. dollar could have a material adverse effect on the ability of our
customers to pay for our services. A currency devaluation could also result in
our customers seeking to renegotiate their contracts with us or, alternatively,
defaulting on or canceling their contracts.

Marketing, Sales and Customer Care

    We view our relationship with our customers as a long-term partnership in
which customer satisfaction is critically important. For this reason we employ
a methodical marketing, sales and customer service strategy in each of our
local markets. This strategy is supported by our local marketing teams and our
U.S.-based corporate sales and marketing professionals. We employ these
strategies with the goal of acquiring and retaining the most attractive
customers in each of our local markets.

    Marketing

    Each of our local markets has a marketing staff which supports the sales
efforts by two primary efforts. The first is through targeted marketing and
advertising efforts such as print promotions, event

                                       47
<PAGE>

participation, public relations and local advertising. Our local staffs
coordinate closely with our U.S.-based marketing professionals to ensure
consistency of our brand across our markets. The second is through market
research and geographic and market segmentation. Our local marketing staffs
assist our sales professionals in identifying new customers in targeted new
buildings.

    Sales

    In each of our markets we use three different sales channels to reach our
target customers and plan to introduce a fourth channel.

    Carriers, Integrators and Internet service providers. Each local market has
a group of experienced sales professionals who focus on other carriers, systems
integrators and Internet service providers. This segment of the market is an
attractive customer base given their significant use and need for bandwidth.

    Key Accounts. Our key account sales professionals focus on large corporate
end users who demand maximum availability and unlimited usage at high speeds
and quality levels.

    Building-Centric Sales. Our building-centric sales staffs in each local
market are designed to complement and leverage the work of the two other sales
channels. These professionals focus on selling to new customers in buildings in
which we already have a customer in order to maximize building penetration as
well as to customers in targeted new buildings.

    Enhanced Internet Service Sales. We plan to hire a new sales and marketing
force within each market dedicated to enhanced Internet services.

    Our sales representatives receive a competitive base salary and a series of
individual bonuses. Their bonuses are based on their attaining certain sales
quotas measured on a monthly basis. The fixed and variable mix of compensation
varies by individual and by market. We believe that our compensation plan will
motivate our sales representatives to provide top quality attention and
service.

    Customer Care

    We believe that our ability to provide our customers with a superior level
of service gives us an important competitive advantage. For this reason, we
seek to provide each of our customers with the highest quality service
available. We provide customer service 24 hours a day, 7 days a week, 365 days
a year and commit to giving customers quick and effective responses to
questions or problems they may have with their service.

Operations and Business Support Systems

    Overview

    Our current operations and business support systems are organized to
support four main areas: network management, customer provisioning, billing and
accounting and financial management systems. These systems adequately support
our existing needs.

    We are in the process of replacing our existing operational support systems
with new enhanced systems that we expect will allow us to manage our
anticipated growth and increased service offerings, as well as integrate the
components of our operations. We believe that the systems we have chosen will
allow us to increase the level of sophistication as needed by the business.
Once implemented, these systems should enable us to effectively manage and
monitor our network, process orders, provide customer services, track usage and
accurately bill our clients with one integrated bill. A goal of our operations
and business support systems is to provide each of our departments with an
integrated view of all provisioning, billing, customer service and collection
activities. We expect to complete the installation of our operating and
business support systems in 2001.

                                       48
<PAGE>

    Service Order Entry and Provisioning

    Our strategy has been to acquire sophisticated off-the-shelf technology
that can be easily and cost-effectively configured by our in-house information
technology staff. Our order processing system provides:

  . One point of entry for orders;

  . Customer access to systems to monitor the performance of services
    provided to them;

  . Ability to enter orders online and track orders throughout the process;
    and

  . Inventory integration to enable ease of provisioning and circuit
    selection.

    Billing

    Our current billing system consists of commercially available software for
flat rate billing. This system allows us to effectively produce invoices and
bill customers for all services we presently offer. However, our current
billing system is not sufficient to accommodate the full billing needs we will
have once we introduce voice and enhanced Internet services. We are in the
process of identifying new billing systems that will allow us to provide these
additional services on a broad scale.

    Customer Service

    Our current systems have allowed us to meet our goals to deliver a high
level of personalized service to our clients and to be proactive. As our
products and services expand, we will need to have customer care functions that
will support a "single view" of all customer data, including billing, order
processing, trouble ticket and call history.

Competition

    We face varying degrees of competition in each of our markets and we expect
to encounter increasing competition in the future. The principal competitive
factors in our markets include network capability and flexibility, scope and
quality of services and timely introduction of new services, brand name
recognition, customer service, technical expertise and functionality, system
engineering expertise, ability to maintain and expand distribution channels,
financial resources and management capabilities. We compete on the basis of the
high quality of our local fixed wireless broadband access networks, short
installation time (including our experience in securing access to customer
buildings) and customer service.

    Our competitors fall into three broad categories:

  . Incumbent exchange carriers in each country in which we operate;

  . Large communications carriers that compete with us on a pan-regional
    basis; and

  . Private local communications carriers in each country in which we
    operate.

    Incumbent Exchange Carriers

    In the past 10 years, most incumbent exchange carriers in Latin America
have been privatized. Representative examples of acquiring companies have
included large international telecommunications providers such as Telefonica
(in Argentina, Brazil and Peru), France Telecom and Telecom Italia (joint
venture in Argentina) and Cable and Wireless (in Panama). Historically, the
incumbent carriers have focused on local and long-distance voice services. In
addition, the incumbent carriers have a dominant share of the underdeveloped
data access services market in each of the countries in which we compete. In
the future, the incumbent exchange carriers may dedicate an increasing amount
of resources to providing data access as this market grows and to offering
basic Internet access and enhanced Internet services. These entities have
significantly greater financial and other resources than we do, including
greater access to financing. See "Risk Factors--We face significant competition
throughout Latin America."

    Pan-regional competitors

    Our primary competitors on a pan-regional basis include:

  . AT&T Latin America, a company recently formed by AT&T through its
    acquisition of NetStream (Brazil) and its pending merger with FirstCom
    (Colombia and Peru), each a fiber-based network provider and Keytech (in
    Argentina). Upon completion of these acquisitions, AT&T Latin America
    will compete with us in various markets, including Brazil, Colombia, Peru
    and to a lesser degree in Argentina.

  . COMSAT Corp., a provider of voice, data and Internet communications
    services to corporate customers using satellite and other technologies in
    various countries in Latin America, including Argentina, Brazil, Colombia
    and Peru.

  . GLOBAL ONE, an international provider of telecommunications services for
    corporate clients, controlled by France Telecom and focused in Brazil and
    Latin America generally.

  . IMPSAT Fiber Networks, Inc., a provider of private telecommunications
    networks, data and Internet services to corporate customers in various
    Latin American countries, including Argentina, Brazil, Colombia and Peru.

  . MetroRED Telecommunications, a fiber-based local communications provider
    in Argentina, Brazil and Mexico that competes directly with us in many of
    our service offerings.

  . PSINet, a US-based global provider of Internet services and
    infrastructure to businesses, which provides Internet connectivity and
    Web hosting services. PSINet has acquired a number of Internet service
    providers in Latin America, specifically in Argentina, Brazil, Panama,
    and Uruguay and has announced its intention to dedicate an increasing
    amount of its resources to offering dedicated Internet access and
    enhanced Internet services.

  . VIA NET.WORKS, Inc., an international provider of Internet access and
    services focused on small and mid-sized businesses in Europe and Latin
    America, specifically in Argentina and Brazil.

    Private Local Communications Carriers

    The third category of competitors includes private local communications
carriers that primarily have only a metropolitan or national presence.
Representative examples of data and Internet services providers in this
category are: in Argentina, Fibertel, Techtel and Telelatina; in Brazil, VIS
and Vicom; in Colombia, Americatel, Capitel and Colomsat; in Panama, Charter
Communications; and in Peru, Maurta. Our voice services competitors in this
category include Vesper and Intelig, both in Brazil.

    Rates for data services are not regulated in our countries of operation,
and the prices for our services are strongly influenced by market forces. We
believe that increasing competition will result in pricing declines. We have
faced and expect to continue to face declining prices and may experience
declining margins as the incumbent operators in the countries where we have
operations modernize their facilities, adapt to a competitive marketplace and
place greater emphasis on data telecommunications, and as other companies enter
the Latin American telecommunications market. These price and margin declines
may accelerate if new competitors enter our markets.

    The principal barriers to entry for prospective providers of private
telecommunications network services such as ours are the need to obtain
operating rights and licenses, spectrum licenses if fixed wireless technology
is to be used, the development of the requisite understanding of customer needs
and the technological, commercial and real estate experience and know-how,
infrastructure to provide quality services to meet those needs and capital.

Regulation

  General

    The licensing of telecommunications services and networks and the renewal
of applicable licenses and spectrum grant allocations are regulated by
governmental entities in the markets in which we conduct business. These
matters and other aspects of telecommunications network operations, including
rates charged to customers, may also be subject to public utility regulation in
the countries in which we provide service. Moreover, statutes and regulations
in certain of the markets in which we conduct business impose limitations on
the amount of spectrum that may be owned by telecommunications companies.
Changes in the current regulatory environments in such countries affecting
matters such as interconnection arrangements, requirements for increased
capital investment, regulations affecting our ability to differentiate among
the prices for our services and foreign ownership limitations could have a
material adverse effect on our business and operations. Because of the
uncertainty as to the interpretation of regulations in certain jurisdictions,
there can be no assurance that we will be able to provide planned services in
each jurisdiction and it is possible that we may be prohibited from providing
services we intend to provide in the future in certain jurisdictions.

    We believe that we have a sound and well-informed understanding of and
basis for interpreting the current regulatory framework and that we will be
able to implement our business plans as currently contemplated. However, some
aspects of the law, rules and regulations in the countries in which we operate
are relatively new and still developing. As a result, it is difficult to
determine how regulators will interpret rules, assess compliance and exercise
their powers of enforcement. We expect that in the future further clarifying
interpretations and refinements will be promulgated by the governmental and
regulatory authorities in the countries in which we have operating and spectrum
licenses.

    Telecommunications operating and spectrum licenses are often subject to
ongoing review and, in some cases, modification or early termination for
failure to comply with applicable regulations. Our operating and spectrum
licenses have fixed terms that are renewable. Although there is a presumption
of renewal, there can be no assurance that the renewal of licenses will occur
or that renewal will be on acceptable terms. Failure to meet service or build-
out requirements can result in financial penalties or revocation of the
operating and spectrum licenses. Operating and spectrum licenses may be revoked
for violation of other regulatory authority rules and regulations.

  Compliance with Network Construction, Operation or Build-out Requirements

    We are required to comply with the terms of our licenses and certain
regulatory requirements, such as deadlines by which service must be offered
and/or minimum build-out requirements. We cannot assure you that we will meet
these requirements or that we will not lose any applicable telecommunications
licenses as a result of our failure to meet the requirements. Failure to get
waivers, extensions or similar relief of the relevant deadlines or to otherwise
comply with these requirements may result in financial penalties or revocation
of the affected licenses. As we acquire additional licenses, we expect to be
required to comply with applicable build-out and spectrum usage requirements.

  Argentina

    Regulatory and legal overview. The Secretariat of Communications (SECOM)
and the National Communications Commission (CNC) are the Argentine
telecommunications authorities responsible for the administration and
regulation of the telecommunications industry. The government of Argentina
enacted a series of laws in 1989 to deregulate the telecommunications sector.
In March 1998, the Argentine government announced the demonopolization of
telephony services of Telecom Argentina and Telefonica Argentina, and the
deregulation of local and long distance telephony markets commenced in November
1999. The telecommunications sector is expected to be completely open to
competition in November 2000. Argentina imposes no limitation on foreign
ownership of telecommunications licenses with

                                       51
<PAGE>

the exception of the General License for Telephony Services, the holder of
which must have a local partner as direct or indirect shareholder with an
equity interest of not less than 10% of the capital stock.

    Operating licenses of Diveo Argentina. We have a license to provide
national and international value-added services, including Internet access.
This operating license and applicable regulations issued by the SECOM and CNC
permit us to provide our own national Internet transmission services. We also
have a national license to provide data transmission services. We may only use
our own facilities to provide the international transmission of data and value-
added services beginning in November 2000. At present, only four companies may
provide facilities-based international transmission services. In addition, we
have local and national and international long distance voice
telecommunications licenses. All of our operating licenses have an indefinite
term provided that we fulfill our obligations and do not materially violate any
regulation or law. We may begin to provide local, national and international
voice telecommunications services beginning in November 2000. We have the right
of interconnection with the public switched telephone network (PSTN) as a
result of our local, national and international telephony licenses and pursuant
to applicable laws. Furthermore, interconnection with the PSTN must be on a
nondiscriminatory basis.

    Spectrum licenses of Diveo Argentina. We have the exclusive right to use
600 MHz at 38 GHz, 224 MHz at 23 GHz, and 60 MHz at 10.5 GHz on a block basis
with national coverage. We are authorized to deploy point-to-point and point-
to-multipoint technologies using our 38 GHz and 10.5 GHz frequencies, and
point-to-point technologies using our 23 GHz frequencies. We were also granted
various point-to-point links at 6 GHz, 8 GHz and 15 GHz. All of our spectrum
licenses are for an indefinite period of time.

    Build-out and spectrum usage requirements. The applicable
telecommunications regulations and our installation schedule approved by the
CNC require us to build-out our network and provide service using our
frequencies in cities and regions of Argentina over a five-year period. We were
required to install our initial network and provide service using our
frequencies in Buenos Aires within twelve months from the date when the
installation schedule was approved by the CNC. In addition, we were required to
guarantee our build-out and spectrum usage requirements by contracting with a
bank to issue a performance bond to the SECOM. To date, we have met our build-
out and spectrum usage requirements in a timely fashion, and the performance
bond issued in connection with our build-out obligations expired and no longer
needs to be replaced. The performance bond issued in connection with the
operating and spectrum licenses acquired from Eritown Corporation Argentina
S.A. remains in effect for our build-out and spectrum usage requirements in the
cities of Rosario, Cordoba and Mendoza. Eritown received its spectrum license
in June 1999. We expect to meet our build-out and spectrum usage requirements
in our other Argentine markets in accordance with our installation schedule and
the applicable regulations.

    License and spectrum usage fees and taxes. We are required to pay a usage
fee in connection with the 10.5 GHz, 23 GHz and 38 GHz spectrum licenses. We
received two spectrum fee invoices from the CNC in December 1999; one for
Eritown's 38 GHz spectrum and the other for Diveo's 10.5 GHz spectrum. Both of
these invoices covered the use of the respective spectrum for a period of
several months in 1999. Prior to paying these invoices, in January 2000 the
SECOM suspended frequency payments for the period from January 1, 1999 to March
31, 2000. In February 2000 the SECOM issued a resolution declaring a temporary
administrative state of emergency for a period of 120 days with respect to the
administration and management of the frequency spectrum in Argentina. Despite
receiving spectrum usage invoices for the foregoing bands of spectrum, we
cannot pay these invoices until the CNC verifies the amounts invoiced by the
prior SECOM administration and determines the actual amounts owed for the
period from 1997 to date. Prior to and as a result of the foregoing resolutions
we have not been billed for any other spectrum. Once this 120-day period
expires we believe the CNC will accept payment for the previous invoices, and
we will probably receive additional spectrum fee invoices. We anticipate that
any payments we are ultimately required to make will not restrict or materially
adversely affect our operations.

                                       52
<PAGE>

    We must make a variable payment to the CNC in an amount that increases each
year from 0.6% of our monthly gross revenues in 2000 to 1% in 2004.

  Brazil

    Regulatory and legal overview. The Brazil Ministry of Communications (BMC)
and the National Telecommunications Agency (ANATEL) are the Brazilian
telecommunications authorities responsible for the administration and
regulation of the telecommunications industry. ANATEL is an independent agency
in charge of regulating telecommunications services and performing many of the
tasks formerly performed by the BMC. ANATEL issues specific regulations and
licenses (concessions, authorizations and permissions) and applies the relevant
penalties for any violations of such regulations and licenses.

    Operating licenses of Diveo Brazil. We were granted two licenses from
ANATEL in July 1998, both of which are for indefinite terms. Our Specialized
Network Service license authorizes us to provide a wide range of
telecommunications services, including Internet, data transmission,
international virtual private network services, value-added services, video,
national and international Internet and data transmission.

    Although our Specialized Circuit Service license permits us to provide
point-to-point and point-to-multipoint telecommunications services to final
customers by using wireless, wireline local access circuits or any other type
of technology available from time to time, our spectrum licenses only allow us
to deploy point-to-point technology. The coverage of the Specialized Circuit
Service license is the entire territory of Brazil. Pursuant to our Specialized
Circuit Service license we may use this license to provide the
telecommunications services authorized under our Specialized Network Service
license.

    We have fulfilled our current obligations with respect to our Specialized
Circuit Service and Specialized Network Service licenses, including our
payments for such licenses.

    Spectrum licenses of Diveo Brazil. We have block grants to use 11 GHz, 23
GHz and 38 GHz in each of the following states: Sao Paulo, Rio de Janeiro,
Minas Gerais, Rio Grande do Sul, Santa Catarina and Parana. We also have block
grants to use 7 GHz, 15 GHz and 18 GHz in Minas Gerais, Rio de Janeiro and Sao
Paulo. Our spectrum licenses must be used in connection with our Specialized
Circuit Service license. Our spectrum licenses are non-exclusive. The spectrum
licenses were granted for a term of ten years from the date of the initial
grant.

    Build-out and spectrum usage requirements. We must register each fixed
wireless link in ANATEL's Technical Information System for the Administration
of Radio-Communications and obtain a permit for each microwave station. Upon
registering each link and receiving the corresponding permit for the microwave
station, we have six months in which to install the relevant microwave station
and operate each registered link. This installation time may be extended for an
additional six-month period. Should we fail to install a microwave station for
which a permit has been obtained and consequently fail to operate a link that
was registered within one-year from the grant of the corresponding frequency,
we could lose our right to use that frequency for that particular link if
another company petitions ANATEL to use the same frequency and link within the
same area. We have met this requirement and currently are fulfilling all of our
build-out and spectrum usage requirements in the markets in which we are
operating and in which we plan to commence operations.

    License and spectrum usage fees and taxes. We must pay a spectrum usage fee
for the right to use the spectrum granted to us. This fee is for the term of
the respective license. We have paid this fee for each of our spectrum licenses
and we will not have to pay it again until the end of the first ten-year term.
We are also required to pay two specific telecommunications taxes. A one-time
installation tax (TFI) must be paid within sixty days after installing a radio
and an operation tax (TFF) must be paid in March of each year. The TFF is based
on the capacity of the number of voice channels per bandwidth of spectrum
employed. The TFF is the only variable payment that we must make to ANATEL or
the BMC.

  Colombia

    Regulatory and legal overview. The Colombian Ministry of Communications
(the CMC) and the Telecommunications Regulatory Commission (CRT) regulate the
telecommunications sector in Colombia. The CMC has general rulemaking
authority, supervises and audits the performance of licensees' legal and
contractual obligations, and is responsible for awarding licenses. In
particular, the CMC focuses on obligations related to the technical project
proposals, including frequency use, investment schedules, and range of service
offerings submitted with each license application. The CRT has jurisdiction
over the pricing of certain telecommunications services and is charged with
issuing regulations intended to promote open competition in the
telecommunications industry. In addition, the CRT regulates the pricing aspects
of the relationship between wireless and wireline operators, including
interconnection terms and rates.

    Operating licenses of Diveo Colombia. We have a value-added license with
national coverage. In accordance with this license and the frequencies
discussed below, we may provide national and international value-added
services. Value-added services include, but are not limited to, national
Internet and data transmission services. The term of the license is 10 years,
with a presumption of renewal for an additional period of 10 years provided we
meet the license obligations.

    We have a local carrier license to provide "clear channel" services in and
between the cities of Bogota, Cali and Medellin. The term of the concession is
10 years, with a presumption of renewal for additional periods of ten years
provided we meet the license obligations.

    Spectrum licenses of Diveo Colombia. We have the exclusive right to use 400
MHz at 38 GHz on a block basis, with national coverage. The frequency grant and
the applicable regulations expressly permit point-to-point links and are silent
regarding point-to-multipoint links. However, we believe that point-to-
multipoint links are permissible based on our exclusive right to use the
spectrum. The term of this license is 10 years, with a presumption of renewal
for additional periods of 10 years provided we fulfill our license obligations.
In accordance with the 38 GHz license, we have met our build-out requirements.

    In addition to our block grant, we also have been granted exclusive rights
to use various point-to-point links at 11 GHz, 18 GHz and 23 GHz.

    Build-out and spectrum usage requirements. In accordance with our original
technical project proposal, the value-added license and applicable regulations,
we have fulfilled our obligations to provide value-added service in six cities.
We are currently providing value-added services to clients in Bogota, Medellin,
Cali, Barranquilla, Bucaramanga and Pereira. To date, we have met our value-
added license payments and other obligations, including the issuance of a
performance bond to guarantee our build-out and quality of service
requirements.

    With respect to our local carrier license, we are currently providing
carrier services in Bogota, Cali and Medellin and have met our payments and
other obligations.

    Colombian law requires us to contract with a bank or insurance company to
issue a performance bond in favor of the CMC for each of the value-added and
local carrier licenses for the duration of the licenses. These performance
bonds guarantee service quality and the fulfillment of build-out obligations.
We have performance bonds for both of our operating licenses.

    License and spectrum usage fees and taxes. We are required to pay an annual
spectrum usage fee in connection with the 38 GHz spectrum license. We are also
required to make a variable payment to the CMC (i) with respect to our local
carrier license, in an amount equal to 3% of our gross revenues, less any
payments to telecommunications providers for services such as access and
interconnection charges and (ii) with respect to our value-added license, in an
amount equal to 5% of our gross revenues, less any payments to
telecommunications providers for services such as access and interconnection
charges.

  Panama

    Regulatory and legal overview. The Regulatory Entity of Public Services
(Regulatory Entity) regulates the telecommunications, electricity, water and
sewerage sectors in Panama. The Regulatory Entity issues regulations, grants
all licenses and concessions, and oversees compliance with telecommunications
laws and regulations. In addition, among other functions, the Regulatory Entity
promotes competition, establishes formulas necessary to calculate tariff rates,
imposes sanctions, and resolves disputes among operators. There are currently
no restrictions on foreign ownership in the telecommunications sector in
Panama.

    Telecommunications services in Panama are classified into Type A and Type B
services. Type A services are reserved for Cable & Wireless Panama, S.A., the
incumbent local, national and international exchange carrier, and cellular
services provided by BSC de Panama, S.A. (BellSouth) and Cable & Wireless
Panama, S.A. Cable & Wireless Panama, S.A. has an exclusive monopoly to provide
Type A telecommunications services until January 2003.

    Type B telecommunications services are completely open to competition. Such
services include Internet access, private voice, data transmission and
switching, video, and facsimile retransmission services. Authorization to
provide such services, including the frequencies that may be used in providing
such services, are granted pursuant to an administrative concession by the
Regulatory Entity, and are for a term of 20 years.

    Operating licenses of Diveo Panama. We currently have the following three
operating licenses in Panama to provide Type B services: (i) Internet for
Public Use, which permits the Company to provide Internet access to customers,
with national coverage; (ii) Data Switching with national coverage; and (iii)
Links for High Fidelity Audio, Video and/or Data for Private Use with or
without the Use of the Frequency Spectrum, with coverage in the cities of
Panama City and Colon. This last license permits the deployment of wireless
technology to effect point-to-point and point-to-multipoint transmission. We
also may provide private voice telephony to customers under this last
concession pursuant to regulations issued by the Regulatory Entity provided
that no part of the network carrying the voice transmission is connected to the
PSTN in Panama or abroad unless we receive authorization from Cable & Wireless
Panama S.A. All of our operating licenses are for a period of 20 years, with a
presumption of renewal for additional 20-year periods.

    Spectrum licenses of Diveo Panama. We have the exclusive right to use 896
MHz at 38 GHz and 112 MHz at 18 GHz on a block basis, with coverage in the
cities of Panama City and Colon, using point-to-point and point-to-multipoint
links in connection with our license to provide links for private audio, video
and data signals described above. Transmission requires that one of the two end
points of the link be represented by one of four pre-determined hub sites in
Panama City, or the one designated hub site in Colon. Our spectrum licenses are
for a period of 20 years, with the presumption of renewal for additional 20-
year periods.

    Build-out and spectrum usage requirements. We are required to begin
operations and use our frequencies within sixteen months from the date that the
operating and spectrum licenses were granted.

    License and spectrum usage fees and taxes. We are required to pay annual
spectrum usage fees for our spectrum licenses. We are also required to make a
variable payment of up to 1% of our gross revenues to the Regulatory Entity.
The amount of this payment is set by the Regulatory Entity each year.

  Peru

    Regulatory and legal overview. The Ministry of Transportation,
Communications, Housing and Construction (MTC) and the Organization for
Supervision of Private Investments in Telecommunications

                                       55
<PAGE>

(OSIPTEL) regulate and supervise the telecommunications industry in Peru. The
MTC issues regulations governing the telecommunications industry. The
Specialized Telecommunications Concession Unit (UECT), an agency within the
MTC, is charged with various functions, including: (i) to grant, renew and
cancel concessions, authorizations, permits and licenses; and (ii) to manage
the frequency spectrum and approve the assignment of frequencies. OSIPTEL is
responsible for overseeing private investments in the telecommunications
industry and has jurisdiction over certain telecommunications matters such as
promoting competition, establishing certain tariffs, advising the MTC, and
arbitrating disputes, including interconnection disputes.

    Operating licenses of Diveo Peru. All of our operating licenses have a term
of 20 years, with a presumption of renewal for an additional period of 20
years. We entered into a local carrier license agreement with the MTC. This
agreement grants us the right to operate a local carrier services network to
provide dedicated broadband fixed wireless "clear channel" carrier services to
customers within the department of Lima and the province of Callao. Within 12
months of June 1999, we must have initiated operation with at least one
wireless link in operation in the department of Lima, and we expect to satisfy
this requirement.

    We also have a local carrier license covering the following nine
departments and three provinces: Arequipa, Callao, Chiclayo, Cusco, Huancayo,
Ica, Lima, Maynas, Piura, Santa, Tacna, and Trujillo. Within 12 months of July
1999, we must have initiated operation with at least one wireless link in
operation in the department of Lima and we expect to satisfy this requirement.
In each of the other departments and provinces, we are required to satisfy a
similar requirement within five years of July 1999.

    We have a national and international long distance carrier license for the
transportation of all types of telecommunications signals originating and
terminating within the country and for the transportation of telecommunications
signals originating or terminating in Peru or abroad. Within twelve months of
July 1999, we must offer national and international long distance carrier
services in Lima. We intend to meet this obligation by offering either Internet
or data services during the first year of operations and voice services
beginning in 2001.

    Spectrum licenses of Diveo Peru. All of our spectrum licenses have a term
of 20 years, with a presumption of renewal for additional periods of 20 years.
Concurrently with the granting of the local carrier license, we were assigned
exclusive rights to use 400 MHz at 38 GHz on a block basis, for the Lima and
Callao comprising four principal hubs in Lima and Callao, using point-to-point
and point-to-multipoint links. We also hold various point-to-point links at 11
GHz and 13 GHz for use with the same license. We are not required to use our
frequencies during the first year from the date they were granted. However, we
will use our frequencies in connection with our local carrier license
requirement of providing service within the first year from the date of the
execution of the license agreement. Our spectrum use requirements increase each
year over a period of five years. We currently have an application pending to
secure additional spectrum in Lima.

    We have the exclusive right to use 48 MHz at 2.4 GHz on a block basis in
connection with the local carrier license covering twelve provinces, which is
described above. We are required to use certain frequencies by the end of the
second year from the date the license was granted and the channels we must use
increase each year so that by the end of the fifth year of operations we must
use all our frequencies in Lima and the other cities.

    We also have the exclusive right to use frequencies in connection with
satellite up-links and downlinks for our national and international carrier
license described above. We intend to use this spectrum in conjunction with a
satellite dish located in Lima, and intend to use portions of the same
frequencies for up-links and downlinks within Peru. We must use our frequencies
according to a five-year frequency use schedule, and the channels we must use
increase each year so that by the end of the fifth year of operations we must
use all our frequencies in Peru.

                                       56
<PAGE>

    Pursuant to the Telecommunications Law and the General Regulations, all
public local carrier licensees have the right to connect to the PSTN.
Furthermore, interconnection with the PSTN must be on an equal and
nondiscriminatory basis and the terms and conditions of interconnection
agreements must be negotiated in good faith between the parties in accordance
with the interconnection regulations and procedures issued by OSIPTEL. Peru
imposes no limitation on foreign ownership of local companies holding
telecommunications licenses.

    In conformity with the Telecommunications Law, the General Regulations, and
OSIPTEL's regulations, all telecommunications operators must pay certain fees,
tariffs, and other charges on an on-going basis. We may set our own tariff
levels for our services, subject to certain maximum tariff levels set by
OSIPTEL.

    License and spectrum usage fees and taxes. We are required to pay annual
spectrum usage fees in connection with the spectrum licenses. We are also
required to make a variable payment to the MTC in an amount equal to 2% of our
gross revenues.

  Uruguay

    Regulatory and legal overview. The executive branch of the Uruguay federal
government establishes national telecommunications policy with advice from the
National Telecommunications Board (DNC), the administrative agency that
coordinates and executes such policies. The executive branch, through the
National Ministry of Defense, directly authorizes and controls the installation
of "new telecommunications services." Although that term has yet to be legally
defined, to date the executive branch and the DNC have interpreted it to mean
value-added services, including Internet access, data transmission, and
services that are more technologically advanced than those services rendered
mainly by the analog transmission of basic telephony services. Our services
fall under this concept of "new telecommunications services."

    The National Telecommunications Administration (ANTEL), Uruguay's incumbent
local, national and international exchange carrier, currently has a monopoly to
provide basic local, national and international voice telephony. However, there
is an exception to this rule with respect to certain free trade zones in
Uruguay where several companies were granted authority to provide international
switched voice telephony to PSTNs abroad, provided that their networks are not
connected to ANTEL's network.

    Operating licenses of Diveo Uruguay. In May 1999, the executive branch
authorized us to install and operate a commercial wireless broadband network in
the city of Montevideo for the provision of data transmission services. This
authorization was granted for an indefinite term. The services that we may
provide include Internet access, national and international Internet and data
transmission, and voice telecommunications services not connected to the PSTN.
Any international voice services that require connection to the PSTN must be
authorized by ANTEL.

    Spectrum licenses of Diveo Uruguay. In December 1999, the DNC granted us
the exclusive right to use 480 MHz at 38 GHz on a block basis for an indefinite
period of time, with national coverage, using point-to-point and point-to-
multipoint links. Transmission requires that one of the two end points of the
link be represented by one of two predetermined hub sites.

    Build-out and spectrum usage requirements. We were required to file a final
technical project with the DNC, which includes our hub sites and coverage areas
in Montevideo. This final technical project was filed with the DNC. We have
installed our first hub site to meet our obligation to install the first hub
site by March 31, 2000. We were also required to post a performance bond for
fifteen months, which guarantees the completion of our technical project. The
performance bond was issued to fulfill this obligation. Requirements of an
administrative nature include the registration and approval of radio equipment
by the DNC and annual certifications of our investments.

                                       57
<PAGE>

    License and spectrum usage fees and taxes. We are required to pay annual
spectrum usage fees in connection with the spectrum license. We have fulfilled
our obligation to pay the applicable fee for our 38 GHz frequencies for the
first two years. There is no variable payment currently in effect.

  United States of America

    Regulatory and legal overview. We have a Section 214 Authorization granted
to us by the Federal Communications Commission (FCC). We currently are not

Legal Proceedings

    We are currently a party to litigation involving the exchange of shares of
our subsidiary, Diginet Colombia, for shares of our common stock in our August
1999 restructuring. The litigation, which was filed on December 23, 1999, is
pending in the United States District Court for the District of Columbia.
Communications Resources, Inc. and Datacom Investments Limited, former minority
stockholders of Diginet Colombia, allege fraudulent inducement in connection
with their purchase of shares of Diginet Colombia and that the valuation
underlying the August 1999 share exchange was improperly conducted. The former
minority stockholders have asserted a loss to them of over $10 million and
claims of breach of contract, fraud and breach of fiduciary duty. As relief,
the stockholders seek recission of the August 1999 share exchange, the
performance of another valuation of Diginet Colombia and monetary damages. We
are contesting the stockholders' claims and believe that the claims are without
merit.

    Except for the above action, we are not a party to any material litigation
or proceedings.

                   DESCRIPTION OF OUR FINANCING ARRANGEMENTS

    The following is a summary of the material provisions of agreements
governing some of our indebtedness. This summary is subject to, and qualified
in its entirety by reference to, all of the provisions of these agreements,
including the definition of certain terms therein. Terms used and not defined
herein have the meanings given to them in the documents described herein.

    In June and November 1999, we executed agreements with Ericsson Credit AB
and Lucent Technologies Inc, to borrow up to $300 million and $100 million,
respectively, of long-term vendor financing. The vendor financing agreements
are available in aggregate in tranches of $250 million and $150 million. The
first tranche is currently available while the second tranche of $150 million
is available beginning on January 1, 2001 provided that we have borrowed all of
the first tranche of $250 million and we are in compliance with the terms of
the agreement holding the covenants. The borrower under our financing
agreements is our wholly-owned subsidiary, Diveo, Inc., a Delaware corporation.
Copies of our financing agreements with Ericsson and Lucent are filed as
exhibits to the registration statement of which this prospectus is a part.

    We must use any funds that we borrow under the financing agreements to pay
for equipment and services and other related items purchased from Ericsson or
Lucent, as applicable. We also are able to use a portion of the proceeds to
purchase from third-party vendors equipment and services that are reasonably
related to the design and construction of our network.

    Under the terms of the financing agreements, Ericsson and Lucent have a
secured interest in generally all of our assets, including the equipment
financed under the agreements, as well as the common and preferred stock of the
operating subsidiaries of Diveo, Inc. that we hold.

    Subject to mandatory or optional prepayment under the terms of the
financing agreements, the principal amounts that we borrow will be repayable
over a four year period, beginning in 2002. Our borrowings under the financing
agreements will accrue interest at LIBOR plus an applicable margin. The
financing agreements permit us to make voluntary prepayments of the amounts
that we borrow, but we may not reborrow any amounts that we repay or prepay.
The agreements have standard one-time financing fees and recurring unused
commitment fees.

    Under certain conditions, if we sell or otherwise dispose of or suffer
material losses with respect to our property and fail to reinvest the proceeds,
then we must use such proceeds to prepay the amounts we have borrowed under the
financing agreements. In addition, under specified circumstances, we must also
make mandatory prepayments out of excess cashflow or funds that we receive upon
the issuance of debt securities.

    The obligations of Ericsson and Lucent to make each disbursement under the
financing agreements will be subject to our satisfaction of several ongoing
conditions, including the continued validity of customary representations and
warranties made in connection with the agreements, the maintenance of required
governmental and third-party consents and the continuation of our supply
agreements with Ericsson and Lucent. The financing agreements also contain a
number of covenants that, among other things, limit our ability to:

  . pay dividends;

  . incur additional indebtedness;

  . create liens and other encumbrances;

  . merge or consolidate with another entity;

  . enter into transactions with affiliates;

  . engage in any business other than the telecommunications or Internet
    access provider business;

                                       60
<PAGE>

  . amend our material contracts;

  . sell or otherwise dispose of our assets;

  . invest in other entities;

  . enter into lease agreements; and

  . engage in the speculative build out of our network.

    In addition, the financing agreements require us to comply on an ongoing
basis with certain financial and operating covenants relating to, among other
things, the maintenance of: specified amounts of our gross property, plant and
equipment; specified amounts of revenue; levels of the use of our services by
our customers; our EBITDA; and ratios of debt and secured debt to contributed
capital, secured debt to EBITDA and EBITDA to total cash debt service.

    The financing agreements contain customary events of default.

    An additional basis for default under the financing agreements is a change
of control event, which the agreements define to include: the acquisition by
any entity of more than 40% of the voting power of our securities; our ceasing
to own all of the equity interests of Diveo, Inc. The financing agreements
specify cure periods for some of the events of default listed above, but not
for all of them.

                             Option Grants in 1999

    The following table sets forth information regarding the grant of stock
options for the year ended December 31, 1999 to each of the named executive
officers. The percentages in the table below are based on options to purchase
1,836,321 shares of common stock, granted under our stock option plans in the
year ended December 31, 1999 to our directors, employees, and consultants. The
exercise price per share of each option was equal to the fair market value of
the common stock on the date of grant as determined by the board of directors.
Potential realizable values are net of exercise price before taxes and are
based on the assumption that our common stock appreciates at the annual rate
shown, compounded annually, from the date of grant until the expiration of the
10-year term. These numbers are calculated based on the requirements of the SEC
and do not reflect our estimate of future stock price growth.

Employment Agreements

    David R. Schmieg. We entered into an agreement with Mr. Schmieg to employ
him as our President and Chief Executive Officer, effective April 16, 1999. In

    Leon Garza. We have entered into an employment agreement with Mr. Garza to

1996 and 1999 Stock Option Plans

    Our 1996 stock option plan became effective on October 1, 1996 and was
recently amended on March 22, 2000. Our 1999 stock option plan became effective
on August 12, 1999, and was recently amended on January 26, 2000. The purposes
of the plans are to attract and retain personnel, to provide additional
incentive to employees, directors and consultants by increasing their ownership
interests in our company, and to promote the success of our business. We use
our 1996 plan to provide stock options for our own directors and employees and
we use the 1999 plan for the benefit of the directors and employees of our
subsidiaries. Our board of directors and compensation committee administer the
plans, determine the persons who will receive awards and establish the terms
and conditions of those awards.

    Options granted under the plans may be either incentive or non-qualified
stock options, as determined by the board of directors and/or compensation
committee at the time of grant. Our employees, including officers and
directors, are eligible to receive both incentive and nonqualified stock
options. However, non-employee directors and consultants are eligible to
receive only nonqualified stock options.

    The per share exercise price of incentive stock options granted to an
employee who, at the time of the grant, owns stock representing more than 10%
of the voting power of all classes of stock of Diveo or of any subsidiary, must
be no less than 110% of fair market value on the date of grant. The exercise
price of incentive stock options granted to any other employee must be no less
than fair market value on the date of grant. The board of directors and/or
compensation committee determines the exercise price of nonqualified stock
options at the time of grant.

    The term of each option is established by the board of directors and/or
compensation committee, but may not be longer than ten years. In the case of an
incentive option granted to an employee who, at the time of the grant, owns
stock representing more than 10% of the voting power of all classes of our
stock or of any of our subsidiaries, the term may be no longer than 5 years.
Individual option grants vest over time, as determined by the board of
directors and/or compensation committee, which is generally four years. All
stock options granted under the 1996 plan vest automatically upon a change of
control, as defined in that plan.

    Under the 1996 and 1999 plans, the maximum number of shares that may be
subject to outstanding awards is 3,379,205 and 1,107,976, respectively. As of
March 22, 2000, options for 5,310,346 shares had been granted. Each of the
plans has a 10 year term.

Compensation Committee Interlocks and Insider Participation

    The members of the compensation committee of our board of directors are
Robert Benbow, Robert J. Goad, Muneer A. Satter, David L. Solomon and Kevin
Somerville. No member of the compensation committee serves as a member of the
board of directors or the compensation committee of any entity that has one or
more executive officers serving as a member of our board of directors or
compensation committee.

    Certain of our stockholders who purchased our preferred stock in various
private equity offerings entered into a stockholders' agreement and a
registration rights agreement with us at the time of their investment. The
stockholders' agreement provided generally for representation on the board,
veto rights over certain corporate transactions, certain preemptive rights and
rights of first refusal on sales by fellow stockholders. The stockholders'
agreement will terminate upon closing of this offering. Affiliates of Goldman,
Sachs & Co. participated in the first, second and third tranches of our Class B
preferred stock offering in April, June and August 1999, respectively. Muneer
Satter is a Managing Director in the Principal Investment Area of Goldman
Sachs. In connection with this transaction, on April 16, 1999, we amended and
restated our stockholders' agreement to add affiliates of Goldman Sachs as
parties.

    Affiliates of Columbia Management participated in the first and second
tranches of our Class B preferred stock offering in April and June 1999. Robert
J. Goad is President of Columbia Management. Meritage Private Equity Fund
participated in the second and third tranches of our Class B preferred stock
offering in June and August 1999. David L. Solomon is an Investment Director
for Meritage.

    Certain other stockholders participated in our Class B preferred stock
offering, including Alta Communications. Robert F. Benbow currently serves as
the managing general partner of Alta.

    During fiscal year 1999, we paid David L. Solomon approximately $110,000
under a consulting agreement that called for Mr. Solomon to provide us with
certain financial advisory services. We have terminated the agreement.

    In a series of transactions that took place throughout fiscal year 1999, we
paid approximately $70,000 to Somerville & Company. Somerville & Company, of
which Kevin Somerville is the founder and Chief Executive Officer, provided
human resources consulting services including interviewing and hiring senior
personnel.

    In addition, we granted several directors options to purchase shares of
common stock. The following table provides information regarding stock options
granted to the following directors:

                             PRINCIPAL STOCKHOLDERS

    The following table sets forth certain information known to us regarding
the beneficial ownership of our common stock as of March 31, 2000, as adjusted
to reflect the sale of     shares of common stock in this offering, the
conversion of all outstanding shares of our convertible preferred stock into
shares of common stock upon the closing of this offering and the proposed seven
to one reverse stock split, by:

  . each person or group known by us to own beneficially more than 5% of our
    outstanding common stock;

  . each of our directors;

  . each named executive officer; and

  . all of our directors and executive officers as a group.

    We have determined beneficial ownership in accordance with the rules of the
SEC. Unless otherwise indicated, the persons included in the table have sole
voting and investment power with respect to all shares beneficially owned.
Shares of common stock subject to options that are currently exercisable or are
exercisable within 60 days of March 31, 2000 are treated as outstanding and
beneficially owned, with respect to the person holding these options for the
purpose of computing the percentage ownership of that person. However, these
shares are not treated as outstanding for purposes of computing the percentage
ownership of any other person. Unless otherwise indicated, the business address
of the persons included in the table is Diveo Broadband Networks, Inc., 3201
New Mexico Ave., NW, Washington, D.C. 20016. The percentages in the "After the
Offering" column assume that the underwriters do not exercise their over-
allotment option to purchase up to     additional shares.

                        SHARES ELIGIBLE FOR FUTURE SALE

    Sales of substantial amounts of our common stock in the public market could
adversely affect our common stock's prevailing market price. Upon completion of
this offering, and after the automatic conversion of shares of preferred stock
outstanding prior to this offering, we will have outstanding an aggregate of
    shares of our common stock, assuming no exercise of the underwriters over-
allotment option and no exercise of outstanding options. Of these shares, all
of the shares sold in this offering will be freely tradable without restriction
or further registration under the Securities Act, unless the shares are
purchased by our "affiliates" as that term is defined in Rule 144 under the
Securities Act.

    The remaining 51,394,331 shares of common stock held by existing
stockholders are "restricted securities" as that term is defined in Rule 144
under the Securities Act. Restricted securities may be sold in the public
market only if registered or if they qualify for an exemption from registration
under Securities Act Rule 144 or 701. We summarize these two rules below. Rules
144 and 701 provide that the restricted securities will be available for sale
in the public market on the date that is one year from the date they were
issued, subject to the volume limitations and other conditions of Rule 144.

    The information presented herein is adjusted to reflect the conversion of
all outstanding shares of our convertible preferred stock into shares of common
stock upon closing of this offering and the proposed seven to one reverse stock
split.

Lock-Up Agreements

    All of our officers and directors, the most senior employee of each
operating subsidiary and several of our stockholders, who will own an aggregate
of 52,087,151 shares (of which 2,274,780 shares are issuable upon the exercise
of options) of common stock after this offering closes, have signed lock-up
agreements. Under these agreements, they have agreed, among other things, not
to transfer or dispose of any shares of common stock, or any securities
convertible into shares of common stock, for a period of 180 days after the
date of this prospectus. Transfers or dispositions can be made sooner with the
prior written consent of Goldman, Sachs & Co. This consent may be given at any
time without public notice.

Rule 144

    Under Rule 144, 39,645,336 shares of common stock will be freely tradable
90 days after this offering closes. Of these shares of common stock, 39,099,425
shares are subject to lock-up agreements. In general, under Rule 144, beginning
90 days after the closing of this offering, a person who has owned shares of
our common stock for at least one year would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of:

  . one percent of the number of shares of common stock then outstanding,
    which will equal approximately     shares immediately after this
    offering; or

  . the average weekly trading volume of the common stock on The Nasdaq
    National Market during the four calendar weeks preceding the filing of a
    notice on Form 144 with respect to such sale.

    Sales under Rule 144 are also subject to manner of sale provisions and
notice requirements and to the availability of current public information about
us. Persons who are our affiliates must also comply with the restrictions and
requirements of Rule 144, other than the one-year holding period requirement,
in order to sell shares of our common stock in the public that are not
restricted securities.

    Under Rule 144(k), 585,226 shares of common stock will be freely tradable
after this offering closes. Under Rule 144(k), a person who is not one of our
affiliates at any time during the 90 days preceding a sale, and who has owned
the shares proposed to be sold for at least two years, is entitled to sell the
shares without complying with the manner of sale, public information, volume
limitation or notice provisions of Rule 144. Therefore, unless otherwise
restricted, "Rule 144(k) shares" may be sold immediately upon the completion of
this offering.

                                       74

Rule 701

    As of the date of this prospectus, a total of 4,905,421 shares of common
stock have been issued or are issuable upon the exercise of options. All of
these shares, subject to option vesting, will be eligible for sale in reliance
on Rule 701 beginning 90 days after the closing of this offering. Of these
shares of common stock, 2,274,780 are subject to lock-up agreements. In
general, under Rule 701 as currently in effect, any of our employees,
consultants or advisors who has purchased shares from us in connection with a
compensatory plan or other agreement is eligible to resell such shares 90 days
after the effective date of this offering in reliance on Rule 144, but without
compliance with restrictions, including the holding period, contained in Rule
144.

Registration Rights

    180 days after the completion of this offering, most of our stockholders,
who will own an aggregate of 51,071,921 shares of common stock, will have
registration rights as to their shares. Of these shares of common stock,
50,055,786 shares are subject to lock-up agreements. Under certain
circumstances, these stockholders, or their transferees, will be entitled to
demand that we register their shares. In addition, all of the stockholders who
have registration rights are entitled to piggyback registration. See "Related
Party Transactions--Registration Rights Agreement." After registration, these
shares will be freely tradable without restriction under the Securities Act,
unless the shares are purchased by affiliates. Any sales of securities by these
stockholders could have a material adverse effect on the trading price of our
common stock.

Stock Option Plans

    We intend to file a registration statement under the Securities Act
covering 4,923,743 shares of common stock reserved for issuance under our stock
option plans. As of the date of this prospectus, options to purchase     shares
of common stock were outstanding. The registration statement is expected to be
filed and become effective after the effective date of this offering.
Accordingly, shares registered under such registration statement will, subject
to vesting provisions and Rule 144 volume limitations applicable to our
affiliates, be available for sale in the open market shortly after this
offering closes, and in the case of our officers, directors, the most senior
employee of each operating subsidiary, and most stockholders who have entered
into lock-up agreements, after the 180-day lock-up agreements expire.

                          DESCRIPTION OF CAPITAL STOCK

General

    The information presented herein is adjusted to reflect the conversion of
all outstanding shares of our convertible preferred stock into shares of common
stock upon the closing of this offering and the proposed seven to one reverse
stock split. Our authorized capital stock consists of 477,324,819 shares of
common stock, 67,159,073 shares of non-voting common stock and 403,865,714
shares of preferred stock, each with a par value of $.0001 per share.

Common Stock

    As of the date of this prospectus, there were 3,440,807 shares of common
stock outstanding and held of record by 21 stockholders. Based upon the number
of shares outstanding as of the date of this prospectus and giving effect to
the issuance of    shares of common stock by us in this offering and the
conversion of the outstanding preferred stock upon the closing of this offering
there will be    shares of common stock outstanding upon completion of this
offering.

    Holders of common stock are entitled to one vote for each share held on all
matters submitted to a vote of stockholders. They do not have cumulative voting
rights. As a result, holders of a majority of the shares of common stock
entitled to vote in any election of directors may elect all of the directors
standing for election. Holders of common stock are entitled to receive ratably,
dividends, if any, as the board of directors may declare out of funds legally
available, subject to any preferential dividend rights of any then-outstanding
preferred stock. Upon our liquidation, dissolution or winding up, the holders
of common stock are entitled to receive ratably the net assets available after
the payment of all our debts and other liabilities and subject to the prior
rights of any then-outstanding preferred stock. Holders of the common stock
have no preemptive, subscription, redemption or conversion rights. The
outstanding shares of common stock are, and the shares offered by us in the
offering will be, when issued in consideration for payment, fully paid and
nonassessable. The rights, preferences and privileges of holders of common
stock are subject to, and may be adversely affected by, the rights of the
holders of shares of any series of preferred stock which we may designate and
issue in the future. See "--Preferred Stock."

Non-voting Common Stock

    We have one stockholder who, because of certain bank holding company
regulatory restrictions, owns shares of our non-voting common stock. Our non-
voting common stock is identical to our common stock except in two respects.
First, our non-voting common stock is not entitled to any voting rights, except
as required by law. Second, holders of our non-voting common stock may, at the
option of the holder (unless the holder is subject to certain restrictions
under the Bank Holding Company Act of 1956, as amended, and the regulations
thereunder), convert shares of non-voting common stock into fully paid and non-
assessable shares of common stock on a share-for-share basis.

Preferred Stock

    Upon the consummation of this offering, all of our preferred stock
outstanding immediately prior to this offering will be converted into shares of
our common stock. Therefore, the following information pertains to any
preferred stock that we may issue in the future pursuant to our certificate of
incorporation.

    Following the closing of this offering, the board of directors will be
authorized, without further stockholder approval, to issue from time to time up
to an aggregate of    shares of preferred stock in one or more series. The
board of directors may fix or alter the designations, preferences, rights and
any qualification, limitations or restrictions of the shares of any series,
including the dividend rights, dividend rates, conversion rights, voting
rights, redemption terms and prices, liquidation preferences and the numbers of
shares constituting any series. As of the closing of this offering, no shares
of preferred stock will be outstanding. Although the ability of the board of
directors to designate and issue preferred stock

                                       76
<PAGE>

could provide flexibility in possible acquisitions or other corporate purposes,
issuance of preferred stock may have adverse effects on the holders of common
stock. The effects include:

  . restrictions on dividends on the common stock if dividends on the
    preferred stock have not been paid;

  . dilution of voting power of the common stock to the extent the preferred
    stock has voting rights; or

  . deferral of participation in our assets upon liquidation until
    satisfaction of any liquidation preference granted to holders of the
    preferred stock.

    In addition, issuance of preferred stock could make it more difficult for a
third party to acquire a majority of the outstanding voting stock and
accordingly may be used as an "anti-takeover" device. The board of directors,
however, currently does not contemplate the issuance of any preferred stock and
is not aware of any pending transactions that would be affected by such
issuance.

Warrants

    As of the date of this prospectus, warrants were outstanding to purchase an
aggregate of 368,723 shares of our series A-2 preferred stock at an exercise
price of $3.833 per share. These warrants will expire on the earlier of June 1,
2005 or the closing of an underwritten public offering. Also as of the date of
this prospectus, warrants were outstanding to purchase an aggregate of 576,356
shares of our series B-1 preferred stock at an exercise price of $4.338 per
share. These warrants will expire on April 16, 2009. Generally, each warrant
contains provisions for the adjustment of the exercise price and the aggregate
number of shares issuable upon the exercise of the warrant under certain
circumstances, including stock dividends, stock splits, reorganizations,
reclassifications or consolidations. At the close of this offering, all
outstanding shares of our preferred stock will automatically convert to shares
of our common stock, and all warrants to purchase shares of our series B-1
preferred stock will automatically convert to warrants to purchase shares of
our common stock.

Limitation of Liability and Indemnification Matters

    Our certificate of incorporation limits the liability of our directors to
us or our stockholders to the fullest extent permitted by Delaware law.
Specifically, the certificate of incorporation provides that our directors
shall not be personally liable to us or our stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (1) for any
breach of the director's duty of loyalty to us or our stockholders, (2) for
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, (3) under a provision of Delaware law relating to
unlawful payment of dividends or unlawful stock purchase or redemption of stock
or (4) for any transaction from which the director derives an improper personal
benefit. As a result of this provision, we and our stockholders may be unable
to obtain monetary damages from a director for breach of his or her duty of
care.

    Our bylaws provide for the indemnification of directors and officers and
any person who is or was serving at our request as a director or officer to the
fullest extent authorized by, and subject to the conditions set forth in, the
Delaware General Corporation Law against all expenses, liabilities and losses.
The indemnification provided under the bylaws includes the right to be paid for
expenses incurred in connection with indemnifiable claims. In addition, we
maintain directors' and officers' liability insurance.

Future Sale" for a discussion of transfer restrictions.

    Prior to the offering, there has been no public market for the shares. The
initial public offering price has been negotiated among Diveo and the
representatives. Among the factors to be considered in determining the initial
public offering price of the shares, in addition to prevailing market
conditions, will be Diveo's historical performance, estimates of the business
potential and earnings prospects of Diveo, an assessment of Diveo's management
and the consideration of the above factors in relation to market valuation of
companies in related businesses.

    We have applied to have the common stock quoted on The Nasdaq National
Market under the symbol "   ."

    In connection with the offering, the underwriters may purchase and sell
shares of common stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the underwriters of a greater
number of shares than they are required to purchase in the offering.
Stabilizing transactions consist of certain bids or purchases made for the
purpose of preventing or retarding a decline in the market price of the common
stock while the offering is in progress.

    The underwriters also may impose a penalty bid. This occurs when a
particular underwriter repays to the other underwriters a portion of the
underwriting discount received by it because the representatives have
repurchased shares sold by or for the account of such underwriter in
stabilizing or short covering transactions.

    These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of the common stock. As a result, the price of the
common stock may be higher than the price that otherwise might exist in the
open market. If these activities are commenced, they may be discontinued by the
underwriters at any time. These transactions may be effected on The Nasdaq
National Market, in the over-the-counter market or otherwise.

    At the request of Diveo, the underwriters are reserving up to     shares of
common stock for sale at the initial public offering price to certain of
Diveo's directors, employees and associates through a directed share program.
The number of shares of common stock available for sale to the general public
will be reduced to the extent these persons purchase these reserved shares. Any
reserved shares not so purchased will be offered to the general public on the
same basis as the other shares offered by this prospectus.

    The underwriters may not confirm sales to any discretionary account without
the prior specific written approval of the customer.

    Goldman, Sachs & Co. may use this prospectus in connection with offers and
sales related to market-making transactions in the shares of common stock.
Goldman, Sachs & Co. may act as principal or agent in such transactions,
including as agent for the counterparty when acting as principal or agent for
both counterparties, and may receive compensation in the form of discounts and
commissions, including from both counterparties when they act as agent for both
such parties. Such sales will be made at prevailing market prices at the time
of sale, at prices related to prevailing market prices or negotiated prices.

    Diveo estimates that its share of the total expenses of the offering,
excluding underwriting discounts and commissions, will be approximately $   .
The Underwriters have agreed to reimburse Diveo for certain expenses incurred
by Diveo in connection with the offering.

    Diveo has agreed to indemnify the several underwriters against certain
liabilities, including liabilities under the Securities Act of 1933.

    Pursuant to our shareholders agreement, an affiliate of Goldman, Sachs &
Co. has designated Robert Gheewalla and Muneer Satter as directors. Upon the
consummation of this offering, such affiliate shall no longer have a
contractual right to nominate any directors.

    Because an affiliate of Goldman, Sachs & Co. beneficially owns more than
10% of Diveo's shares, the offering is being conducted in accordance with Rule
2720 of the National Association of Securities Dealers, Inc. That rule requires
that the initial public offering price be no higher than that recommended by a
"qualified independent underwriter," as defined by the NASD. Salomon Smith
Barney Inc. has served in that capacity and has performed due diligence
investigations and reviewed and participated in the preparation of the
registration statement of which this prospectus forms a part.

    The validity of the shares of common stock being offered hereby and other
legal matters will be passed upon for Diveo by Hogan & Hartson L.L.P.,

                                    EXPERTS

    Our consolidated financial statements at December 31, 1999 and 1998 and for
each of the three years in the period ended December 31, 1999 appearing in this
prospectus have been audited by Ernst & Young LLP, independent auditors, as set
forth in their report thereon appearing elsewhere in this prospectus and are
included in reliance upon such report given on the authority of such firm as
experts in accounting and auditing.

                      ENFORCEABILITY OF CIVIL LIABILITIES

    Although we are a corporation organized under the laws of the State of
Delaware, our principal operations are in various Latin American countries.
Substantially all of our assets are located in Argentina, Brazil, Colombia,
Panama, Peru and Uruguay. As a result, investors in our common stock may not be
able to enforce against us in U.S. courts judgments predicated upon the civil
liability provisions of the federal securities laws of the United States. There
is doubt as to enforceability in original actions in courts of each of the
foregoing Latin American jurisdictions of liabilities predicated solely on U.S.
federal securities laws and as to the enforceability in the courts in each of
those Latin American jurisdictions of judgments of U.S. courts obtained in
actions predicated upon the civil liability provisions of U.S. federal
securities laws.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

Board of Directors
Diveo Broadband Networks, Inc.

    We have audited the accompanying consolidated balance sheets of Diveo
Broadband Networks, Inc. (formerly Diginet Americas, Inc.) and subsidiaries as
of December 31, 1999 and 1998 and the related consolidated statements of
operations, stockholders' equity (deficit), and cash flows for each of the
three years in the period ended December 31, 1999. 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 audits.

    We conducted our audits in accordance with auditing standards generally
accepted 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 as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Diveo
Broadband Networks, Inc. (formerly Diginet Americas, Inc.) and subsidiaries as
of December 31, 1999 and 1998, and the consolidated results of their operations
and their cash flows for each of the three years in the period ended December
31, 1999 in conformity with accounting principles generally accepted in the
United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of Business

    Diveo Broadband Networks, Inc. (the "Company"), formerly known as Diginet
Americas, Inc., was incorporated in October 1996 as a Delaware corporation. The
Company has incorporated in Delaware subsidiaries for the purpose of owning the
entities incorporated by the Company in each of the Company's operating
markets.

    The Company seeks to become a leading facilities-based provider of
integrated Internet, data and voice services in high growth urban markets
throughout Latin America. Through the Company's local fixed wireless broadband
access networks, the Company currently provides large and medium-sized
corporations, telecommunications carriers, Internet service providers, content
and e-commerce providers and system integrators with high-speed data transport
and Internet access. The Company's communications services are subject to
varying degrees of governmental regulation in the operating markets. The
Company launched services in Buenos Aires, Argentina in March 1999 and in Sao
Paulo, Brazil in December 1999.

2. Summary of Significant Accounting Policies

Consolidation

    The consolidated financial statements include the accounts of Diveo
Broadband Networks, Inc. and its subsidiaries. All material intercompany
transactions and accounts have been eliminated in consolidation.

Development Stage Company

    During 1999, the Company commenced commercial operations by launching its
services in Buenos Aires, Argentina and Sao Paulo, Brazil. Accordingly, as of
December 31, 1999, the Company is no longer considered to be in the development
stage as defined in Statement of Financial Accounting Standards No. 7,
"Accounting and Reporting by Development Stage Enterprises."

Foreign Currency Translation

    The functional currency of the Company's foreign subsidiaries is the U.S.
Dollar. The monetary assets and liabilities of the Company's foreign
subsidiaries are re-measured into U.S. Dollars at the exchange rate in effect
at the balance sheet date. Non-monetary assets and liabilities are re-measured
at historical rates. Revenues, expenses, gains and losses are re-measured at
the average exchange rates for the period. Resulting re-measurement losses are
recognized in results of operations and amounted to $4,000, $6,000 and $179,000
for the years ended December 31, 1997, 1998 and 1999, respectively. Foreign
currency gains or losses resulting from transactions being denominated in
currency other than the local currency have not been significant to date.

Use of Estimates

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make use of estimates and
assumptions that affect amounts in the financial statements and accompanying
notes. Actual results could differ from those estimates.

                                      F-7

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)


Business and Concentrations of Credit Risk

    The Company is developing communications systems in Latin America. Each of
the Company's subsidiaries has a unique and distinct market, operating
environment, and local economy. Achieving each operating plan is dependent on
successfully contending not only with normal risks associated with constructing
and operating communication networks, but also risks unique to operating in
foreign countries, such as regulatory compliance, contractual restrictions,
labor laws, expropriation, nationalization, political, economic or social
instability, and confiscatory taxation.

    The Company places its cash and investments with financial institutions.
Essentially all of the Company's cash and short-term investments are with two
institutions at December 31, 1999. The Company's cash and short-term
investments are comprised mainly of high-credit quality corporate commercial
paper and money market funds. As a result, substantially all of the cash, cash
equivalents and short-term investments at December 31, 1999 are uninsured.
Management believes that the financial risks associated with such investments
are minimal. With respect to accounts receivable, the Company performs ongoing
credit evaluations of its customers, generally does not require collateral, and
maintains an allowance for doubtful accounts based on historical experience and
management's expectations. For the year ended December 31, 1999, one customer
in Buenos Aires, Argentina represented approximately 20% of the Company's
consolidated revenues.

Financial Instruments

    The carrying value of the Company's financial instruments including cash
and cash equivalents, accounts receivable, accounts payable and accrued
liabilities and equipment financing debt approximates fair value.

Cash and Cash Equivalents

    The Company considers all highly liquid investments purchased with an
original maturity of less than three months to be cash equivalents. Cash
equivalents consist of cash in banks, insured money market accounts, money
market mutual fund shares and qualifying corporate commercial paper.

    Included in prepaid expenses and other current assets is approximately
$600,000 of restricted cash at December 31, 1999. The restricted cash
represents cash held in escrow in connection with the Company's acquisition of
spectrum and an operating license in Peru (see Note 4).

Short-Term Investments

    Short-term investments consist of high-credit quality commercial debt and
shares of mutual funds that invest in short and medium term U.S. government
bonds and T-bills with maturities of less than one year. The short-term
investments are classified as available for sale and the carrying amount
approximates fair value.

Recoverable Taxes

    Recoverable taxes relate to value-added taxes (VAT) incurred on the supply
of goods and services purchased by the Company and are eventually borne by the
final consumer. VAT payments made by the Company on the build-out of its
communications networks are recovered from customers as services are provided.
Since the Company believes that the value-added tax receivable is realizable,
the Company has not recorded a reserve against the asset.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)


Property and Equipment

    Property and equipment is stated at cost. Depreciation and amortization are
computed using the straight-line method over the estimated useful lives of the
related assets beginning on the date those assets are put in service.

    The Company constructs certain of its own network systems and related
facilities. Certain internal costs directly related to the construction of such
facilities, including a portion of the salaries, benefits and taxes of some
employees are capitalized. The Company also capitalizes interest expense, to
the extent incurred, as a component of the cost of the construction of its own
network systems and related facilities. During the year ended December 31,
1999, the Company capitalized interest expense of $185,000.

    As of December 31, 1999, portions of the Company's telecommunications
service equipment was in use in a testing phase for several customers in
Colombia and certain markets in Brazil. Accordingly, such telecommunications
service equipment was not being depreciated during 1999.

    Costs incurred during the application development stage for internal use
software, as well as costs incurred for website development, are capitalized as
incurred in accordance with Statement of Position No. 98-1, "Accounting for the
Cost of Computer Software Developed or Obtained for Internal Use." Such costs
amounted to approximately $0, $55,290, and $541,011 during the years ended
December 31, 1997, 1998 and 1999, respectively. The Company amortizes the
capitalized amounts over a three-year period.

Spectrum and Operating Licenses

    Spectrum and operating licenses are amortized using the straight-line
method over the license grant period, usually 10 to 20 years, beginning the
date the license is granted to the Company. Acquired spectrum and operating
licenses are amortized using the straight-line method over the remaining
license grant period. The Company is currently amortizing its spectrum and
operating licenses for Argentina, Brazil, Colombia, Panama and Peru. The
Company is required to pay recurring fees to maintain its spectrum and
operating licenses. Such fees are expensed as incurred.

Other Assets

    Included in other assets is approximately $2.5 million of debt issuance
costs that originated in connection with the Company's equipment financing
debt. The Company is amortizing the debt issuance costs to interest expense
over the five year term of the related equipment financing debt.

    During 1999, the Company and certain of its subsidiaries entered into three
party arrangements with a financial institution whereby an aggregate of
approximately $4.1 million was borrowed by the subsidiaries and concurrently, a
like amount certificate of deposit was placed at the financial institution by
the Company. The arrangements establish a right of setoff and, accordingly, the
amounts have been netted for purposes of the consolidated financial statement
presentation.

Recoverability of Long-Lived Assets

    The recoverability of licenses and property and equipment is dependent upon
the successful build-out of communication networks, especially fixed wireless
communication networks, in each of the respective markets in which the Company
plans to be operating or through the sale of such assets.

                       (FORMERLY DIGINET AMERICAS, INC.)

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)


    In accordance with Statement of Financial Accounting Standards No. 121,
Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of, management periodically reviews, if an impairment indicator
exists, the carrying value and lives of spectrum licenses and property and
equipment it owns. If the expected future cash flows from the use of these
assets (undiscounted and without interest charges) are less than the carrying
value, the Company's policy is to record a write-down that is determined based
on the difference between the carrying value of the asset and its estimated
fair value. During 1999, the Company recorded an impairment charge related to
capitalized spectrum and operating license costs for Mexico. See Note 4.

Stock-Based Compensation

    The Company accounts for its stock-based compensation in accordance with
APB No. 25, Accounting for Stock Issued to Employees ("APB 25") using the
intrinsic value method. Stock-based compensation related to options granted to
non-employees is accounted for using the fair value method in accordance with
Statement of Financial Accounting Standard No. 123 "Accounting for Stock-Based
Compensation" ("FAS 123"). The Company has made pro forma disclosures required
by FAS 123 for all options granted.

Revenue Recognition

    Revenues from providing digital dedicated access and Internet access and
connectivity services are recognized as services are rendered based on
contractual access fees. The Company provides services to customers under
contracts that typically range from one to three years. The Company provides
services to end-user business customers and to other telecommunications service
providers, Internet service providers and systems integrators.

    The Company recognizes non-refundable installation fees upon the customers'
acceptance of the completed installation.

Advertising Costs

    The Company expenses advertising as incurred. Advertising expense was $0,
$231,000, and $1,326,000 for the years ended December 31, 1997, 1998, and 1999,
respectively.

Start-Up Costs

    The Company has expensed all start-up costs as incurred since inception.

Income Taxes

    The Company accounts for its income taxes using the liability method.

Comprehensive Loss

    For the years ended December 31, 1997, 1998 and 1999, the Company's net
loss reflects comprehensive loss and accordingly, no additional disclosure is
presented.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)


Net Loss Per Share and Pro Forma Net Loss Per Share

    Basic net loss per share is based on the weighted average shares
outstanding during the period. Diluted net loss per share increases the shares
used in the basic net loss per share calculation by the dilutive effects of
options, warrants, and preferred stock. The Company's common stock equivalent
shares outstanding from stock options, warrants and preferred stock are
excluded from the diluted net loss per share computation as their effect is
antidilutive.

    Pro forma net loss per share for the year ended December 31, 1999 is
computed using the weighted average number of common shares outstanding,
including the pro forma effects of the automatic conversion of the Company's
Class A Preferred Stock and Class B Preferred Stock into shares of the
Company's common stock as if such conversion occurred at the later of January
1, 1999 or the date of original issuance. The resulting pro forma adjustment
includes an increase in the weighted average shares used to compute basic and
diluted net loss per share of 24,412,237 shares for the year ended December 31,
1999.

amounted to $263,190 and $912,805 at December 31, 1998 and 1999, respectively.

    The Company has acquired all of the outstanding stock of two companies: (a)
Tellink, S.A. ("Tellink") located in Peru and (b) Eritown Corporation Argentina
S.A. ("Eritown") located in Argentina. The Company acquired Tellink on December
17, 1999 for $1.2 million, which consisted of $600,000 of cash and $600,000 of
cash held in escrow (restricted cash) to be released to the seller upon
expiration of the escrow period assuming no claims exist against the seller.
This escrow amount will be released in 2000. The Company acquired Eritown in
October 1999 for $2.0 million of cash. The assets of Tellink and Eritown
consisted entirely of the spectrum and operating licenses and therefore, the
Company has allocated the entire purchase price to the spectrum and operating
licenses acquired and is amortizing the licenses over the remaining grant
period (7-10 years), in accordance with the Company's policy.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)


    The Company capitalizes costs related to efforts to gain spectrum licenses
or operating licenses in existing and new markets. As of December 31, 1998 and
1999, the Company has capitalized approximately $331,000 and $353,000,
respectively, of costs related to markets in which the Company has not yet
obtained a spectrum or operating license. Management believes there is a high
likelihood of success for obtaining licenses in these markets.

    Management periodically reviews the status of all spectrum and operating
license efforts in each target market and estimates the probability of success
of the process. If and when the success of a spectrum or operating license in
any market is deemed less than likely, costs capitalized related to that effort
are written-off to the statements of operations. In connection with this
policy, during the year ended December 31, 1999, the Company wrote off
approximately $105,000 of costs previously capitalized related to the Company's
spectrum and operating license efforts in Mexico.

5. Performance Bonds

    During 1997, in connection with obtaining the Company's spectrum and
operating license in Colombia, the Company was required to obtain a performance
bond of $340,000 in favor of the Colombian telecommunications regulatory body.
During 1999, the Company was required to obtain a performance bond of $300,000
in favor of the Uruguayan telecommunications regulatory body related to a grant
of fixed wireless spectrum. The performance bonds are fully backed by U.S.
dollar denominated deposits held at various financial institutions. These
deposits are classified as other assets on the balance sheets. Release of the
performance bonds, and, therefore, release of the cash collateral, is dependent
on the Company's achievement of certain service offering, investment or network
build out requirements. As of December 31, 1999, the Colombian and Uruguayan
performance bonds were still outstanding.

    Provisions of the equipment financing agreements require the Company to
meet certain financial, operational and other covenants. As of December 31,
1999, the Company was in compliance with all financial covenants.

    Under the terms of the equipment financing agreements, Ericcson Credit AB
and Lucent Technologies, Inc. have a secured interest in generally all assets
of the Company, including the equipment financed under the facilities, as well
as the common and preferred stock held by the Company of its U.S. and Latin
American subsidiaries.

    The equipment financing agreements restrict, to a certain extent, the
Company's ability to engage in certain lines of business, incur additional
borrowings, pay dividends or acquire or merge with another entity.

7. Note Payable to Related Party

    In June 1998, upon the closing of an equity investment by unrelated third
parties, the notes payable to a related party (also an investor), including
both the principal and accrued interest, were exchanged for cash and preferred
stock. The amount due on the first note, $1,137,401 consisting of $1,064,300 of
principal and $73,101 of accrued interest, was redeemed for cash. The total
amount due under the second note, $625,729, consisting of $544,254 of principal
and $81,475 of accrued interest, was redeemed in exchange for shares of the
Company's Class A Preferred Stock. The exchange was effected at the fair market
value of the Company's Class A Preferred Stock, as determined by the price paid
for the Class A Preferred Stock by new investors.

    Interest expense related to these notes payable for the years ended
December 31, 1997, 1998, and 1999 was $85,700, $68,900 and $0, respectively.

8. Convertible Debentures and Warrants

    During 1997 and 1998, the Company issued promissory notes ("the Notes")
with an aggregate principal of $3,250,000 and $5,500,000 in exchange for cash.
In connection with the Notes, the Company issued to the holders of the Notes
warrants to purchase 329,048 shares of the Company's Class A Preferred Stock
(Series A-2 Preferred Stock) at an exercise price of $3.8325. The warrants are
exercisable through June 2008.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)


    In June 1998, as a result of the closing of a private placement of equity
securities, all amounts payable under the Notes, $8,750,000 in principal and
$483,389 in accrued interest, became due. The holders of the Notes exercised
their options under the terms of the Notes by exchanging the Notes and accrued
interest for cash and preferred stock. The Company made cash payments on the
Notes of $546,389, that consisted of $500,000 of principal and $46,389 of
accrued interest. The balance of the Notes, $8,687,000, consisting of
$8,250,000 of principal and $437,000 of accrued interest, was converted to
1,345,819 shares of Class A preferred stock pursuant to the conversion price
terms of the Notes. The conversion price of the Notes was based on the fair
market value of the Class A preferred stock, as determined by the cash price
paid by new investors.

    Interest expense for the years ended December 31, 1997 and 1998 related to
the Notes was $195,000 and $288,389, respectively.

9. Stockholders' Equity (Deficit)

    The Company's Certificate of Organization provides for the following
classes of capital stock: Class A Convertible Preferred Stock, Class B
Convertible Preferred Stock, Common Stock, and Non Voting Common Stock.

Class A Preferred Stock

    In June 1998, the Company issued 8,077,782 shares of Class A Convertible
Preferred Stock ("Class A Preferred Stock") in an equity financing round that
yielded $30,957,795 less approximately $429,000 in equity issuance costs. This
equity financing round included the conversion of the principal and accrued
interest on substantially all of the Notes outstanding (see Note 8) and a
portion of the principal and interest owed to a related party (see Note 7) into
shares of the Company's Class A Preferred Stock. New funds available to the
Company from the equity financing, net of the principal and interest on the
conversion of debt and net of expenses related to the closing of the equity
financing, approximated $19,533,000. In connection with the Class A Preferred
Stock financing, the Company issued warrants to purchase 329,048 shares of
Class A Preferred Stock (Series A-2 Preferred Stock, terms discussed below) at
an exercise price of $3.8325 per share, exercisable over a ten-year term.

    The holders of Class A Preferred Stock are entitled to receive dividends,
compounded annually from the date of issuance, when declared by the Board of
Directors; however, the Board of Directors may elect to defer such payments
until such time as it determines dividends shall be paid. All accumulated and
unpaid dividends on Class A Preferred Stock will be canceled upon conversion of
the Class A Preferred Stock into common stock.

    At any time, each holder of Class A Preferred Stock may convert shares of
Class A Preferred Stock into common stock based on the conversion ratio
disclosed in the above chart, subject to adjustment under certain
circumstances. Conversion is automatic in the event of a public offering of
common stock with aggregate net proceeds of at least $50 million and in which
the gross offering price meets certain specified criteria. At any time, the
holders of Series A-1 Non Voting Preferred Stock may convert all or a portion
of shares into shares of Series A-1 Voting Preferred Stock. The holders of
Series A-1 Voting Preferred Stock and Series A-2 Preferred Stock are entitled
to the number of votes per share equal to the number of shares of common stock
into which such shares of voting preferred stock are convertible in accordance
with the conversion rights described in the above chart. The preferred stock,
including accrued dividends, have preference over common stock in the event of
a liquidation of the Company. Liquidation is defined by the Stock Purchase
Agreement for Series A as the dissolution of the Company through bankruptcy or
other winding up or the sale of substantially all the shares or assets of the
Company. After payment of the liquidation preference, described in the above
chart, to the holders of preferred stock, the remaining assets of the Company
shall be distributed between holders of preferred stock and common stock.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)

(the "1996 Plan") and the Diveo Broadband Networks, Inc. 1999 Stock Option Plan
(the "1999 Plan") (together referred to as the "Plans"). Under the Plans,
options to purchase shares of the Company's common stock may be granted to key
employees, consultants and members of the Board of Directors, as authorized by
the Board of Directors. Awards consist of both non-qualified options and
options intended to qualify as "incentive" stock options under the Internal
Revenue Code. The exercise prices for options granted pursuant to the Plans are
to be set by the Plans' Administrator as directed by the Board of Directors.
The Plans' Administrator, as directed by the Board of Directors, also
establishes the vesting term of the stock options granted.

    As of December 31, 1999, there were 2,318,062 and 915,918 share options
authorized for grant under the 1996 Plan and 1999 Plan, respectively.

    Since inception (October 1, 1996) through June 30, 1999, the Company
maintained common stock incentive plans for consultants and employees of each
of the Company's subsidiaries (the "Subsidiary Plans"). Under the Subsidiary
Plans, options to purchase an aggregate of 687,357 shares of the subsidiaries'
common stock may be granted to key employees and consultants. As in the Plans,
awards in the Subsidiary Plans consist of both non-qualified options and
options intended to qualify as "incentive" stock options under the Internal
Revenue Code. The exercise prices for options granted pursuant to the
Subsidiary Plans are to be set by the Subsidiary Plan Administrator as directed
by the Board of Directors and may be less than the fair market value of the
common stock on the date of the grant. The Subsidiary Plan Administrator, as
directed by the Board of Directors, also establishes the vesting term of the
stock options granted.

    The Subsidiary Plans provided for a "roll-up" provision whereby each
outstanding share of the subsidiaries' common stock (not held by the parent)
and all outstanding stock options to purchase the subsidiaries' common stock
will automatically be exchanged for common stock and stock options in the
Company, respectively, upon the occurrence of a qualifying public offering or
change in control of the Company. The exchange ratios are determined based on
the value of each subsidiary relative to the Company as a whole, as determined
by one of twelve U.S. based investment banks. During 1999, in connection with
the Company's Class B Preferred Stock equity financing, the roll-up provision
was triggered and accordingly, each outstanding share of the subsidiaries'
common stock (not held by the parent) was exchanged for common stock of the
Company. In addition, all outstanding stock options to purchase the
subsidiaries' common stock was exchanged for stock options in the 1999 Plan
based on the exchange ratios determined by the valuation that the Company
obtained. Upon the completion of the roll-up, there were no further grants
under the Subsidiary Plans.

    The Company has recorded approximately $0, $72,000, and $47,000 in expense
during the years ended December 31, 1997, 1998 and 1999, respectively, for the
fair value of options issued to consultants or employees for past services
rendered to the Company.

    The fair value of each option grant was estimated on the date of grant
using the Black-Scholes option-pricing fair value model with the following
weighted-average assumptions used for all grants: dividend yield of 0% for
1997, 1998, and 1999, risk-free interest rate of 6.6%, 5.0%, and 5.5% for 1997,
1998, and 1999, respectively, volatility of 70% for all periods and expected
life between 2 and 6 years.

    The weighted average fair values of options granted during 1997 were $.07
per share--the Plans, and $.07 per share--Subsidiary Plans. The weighted
average fair values of options granted during 1998 were $0.14 per share--the
Plans, and $.07 per share--Subsidiary Plans. The weighted average fair value of
options (including options granted under the Subsidiary Plans exchanged into
options under the Plans) granted during 1999 was $1.74 per share.

11. Income Taxes

    Under FAS 109, deferred income taxes are recognized for temporary
differences between financial statement and income tax bases of assets and
liabilities, loss carryforwards and tax credit carryforwards for which income
tax benefits are expected to be realized in future years. A valuation allowance
is established to reduce deferred tax assets if it is more likely than not that
all or some portion of such deferred tax assets will not be realized. The
effect on deferred taxes of a change in tax rates is recognized in income in
the period that includes the enactment date.

    The tax effect of temporary differences as of December 31, 1998 and 1999 is

a result of these restrictions.

12. Commitments and Contingencies

Operating Leases

    The Company's offices, except for those leased in Brazil, are leased under
non-cancelable operating leases expiring through 2003. The office lease in
Brazil has a base term of three months, which is renewable at the Company's
option. The Company also leases sites to place its equipment on various
rooftops under substantially the same terms as its office leases. The Company's

</TABLE>

    Rent expense for the years ended December 31, 1997, 1998, and 1999 was
$39,812, $330,279, and $1,601,238, respectively.

Purchase Commitments

    As of December 31, 1999, the Company had committed to purchase
communications equipment from a vendor by issuing a non-cancelable purchase
order to purchase approximately $12,500,423 of communications equipment and
services. Under the financing agreement with Lucent Technologies, Inc., the
Company is required to purchase $25 million of products and services over the
initial five-year term of the agreement.

Litigation

    The Company is currently a party to litigation involving the exchange of
shares of its subsidiary, Diginet Colombia, for shares of common stock of the
Company effected in connection with the roll-up of the Company's stock option
plans (see Note 10). The litigation, which was filed on December 23, 1999, is
pending in the United States District Court for the District of Columbia.
Communications Resources, Inc. and Datacom Investments Limited, former minority
stockholders of Diginet Colombia, allege fraudulent inducement in connection
with their purchase of shares of Diginet Colombia and that the valuation
underlying the share exchange was improperly conducted. The former minority
stockholders have asserted a loss to them of over $10 million and claims of
breach of contract, fraud and breach of fiduciary duty. As relief, the
stockholders seek recission of the share exchange, the performance of another
valuation of Diginet Colombia and monetary damages. The Company is contesting
the stockholders' claims and believe that the claims are without merit. It is
management's position, based on a review by outside counsel, that it is not
possible to estimate the amount of loss, if any, that might result from this
action. Accordingly, no provision for this matter has been made in the
Company's consolidated financial statements.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The Third Restated and Amended Certificate of Incorporation and the Bylaws
of the Registrant provide for the indemnification of the Registrant's directors
and officers to the fullest extent authorized by, and subject to the conditions
set forth in the General Corporation Law of the State of Delaware (the "DGCL"),
except that the Registrant will indemnify a director or officer in connection
with a proceeding (or part thereof) initiated by such person only if such
proceeding (or part thereof) was authorized by the Registrant's Board of
Directors. The indemnification provided under the Restated Certificate of
Incorporation and Bylaws includes the right to be paid by the Registrant the
expenses (including attorneys' fees) in defending of any proceeding for which
indemnification may be had in advance of its final disposition, provided that
the payment of such expenses (including attorneys' fees) incurred by a director
or officer in advance of the final disposition of a proceeding may be made only
upon delivery to the Registrant of an undertaking by or on behalf of such
director or officer to repay all amounts so paid in advance if it is ultimately
determined that such director or officer is not entitled to be indemnified.
Pursuant to the Bylaws, if a claim for indemnification is not paid by the
Registrant within 60 days after a written claim has been received by the
Registrant, the claimant may at any time thereafter bring an action against the
Registrant to recover the unpaid amount of the claim, and, if successful in
whole or in part, the claimant will be entitled to be paid also the expense of
prosecuting such action.

    As permitted by the DGCL, the Registrant's Restated Certificate of
Incorporation provides that directors of the Registrant shall not be liable to
the Registrant or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Registrant or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL, relating to
unlawful payment of dividends or unlawful stock purchase or redemption or (iv)
for any transaction from which the director derived an improper personal
benefit. As a result of this provision, the Registrant and its stockholders may
be unable to obtain monetary damages from a director for breach of his or her
duty of care.

                                      II-3
<PAGE>

this Registration Statement, or otherwise, 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 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 a 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 that:

    (1) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in the form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective; and

    (2) For the purposes of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus 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.

the Lenders ratably according to their respective Tranche A Commitments. Amounts
borrowed hereunder and repaid or prepaid may not be reborrowed.

                                       27



     (b) The Tranche B Advances. Each Lender having a Tranche B Commitment
severally agrees, on the terms and conditions hereinafter set forth, to make
Advances (each, a "Tranche B Advance") to the Borrower from time to time on any
Business Day during the period from the Tranche B Effective Date until the
Tranche B Termination Date in an aggregate amount not to exceed at any time
outstanding such Lender's Tranche B Commitment. Each Borrowing consisting of
Tranche B Advances shall be in an amount not exceeding (i) amounts owing under
invoices issued or accepted by the Vendor pursuant to the Supply Agreement
during the calendar month immediately preceding the date of the proposed
Borrowing and that were not paid with the proceeds of any prior Borrowing and
(ii) interest owing on Borrowings to be paid with the proceeds thereof. Each
such Borrowing shall consist of Advances made on the same day by the Lenders
ratably according to their respective Tranche B Commitments. Amounts borrowed
hereunder and repaid or prepaid may not be reborrowed.

     SECTION 2.02. Making the Advances. (a) Each Borrowing shall be made on
notice, given not later than 11:00 A.M. (New York City time) on the third
Business Day prior to the date of the proposed Borrowing by the Borrower to the
Administrative Agent; provided that, except with respect to Borrowings the
proceeds of which shall be used to pay interest owing on Borrowings as permitted
hereunder:

          (i) the Borrower may not give more than one such notice in any
     calendar month; and

          (ii) for any Borrowing proposed to be made after December 31, 1999,
     the date of each Borrowing shall be the twentieth day of each calendar
     month; provided that if such date is not a Business Day, the date of
     Borrowing shall be the next Business Day.

The Administrative Agent shall give to each Lender prompt notice thereof by
telecopier or telex. Each such notice of a Borrowing (a "Notice of Borrowing")
shall be in writing, in substantially the form of Exhibit B, specifying therein:

          (A) the requested date of such Borrowing,

          (B) the requested aggregate amount of such Borrowing,

          (C) the Vendor's invoices to be paid with the proceeds of such
     Borrowing, the respective amounts of such invoices to be paid and the
     aggregate amount of such invoices to be paid, and

          (D) any payments of interest owing on Borrowings to be paid with the
     proceeds of such Borrowing as permitted hereunder.
<PAGE>

                                       28



Each Lender having an applicable Commitment to fund an Advance shall, before
11:00 A.M. (New York City time) on the date of such Borrowing, make available
for the account of its Lending Office to the Administrative Agent at the
Administrative Agent's Account, in same day funds, such Lender's ratable portion
of such Borrowing; provided that if a Commitment is assigned by the Initial
Lender after receipt of a Notice of Borrowing but prior to the Borrowing related
thereto (any such assigned Commitment, a "Fronting Commitment"), and the
Assignment and Acceptance relating thereto specifies such assigned Commitment is
a Fronting Commitment, the Initial Lender's ratable portion of such Borrowing
shall equal (w) the amount the Initial Lender would have funded in respect of
such Borrowing calculated without giving effect to such assignment minus (x) the
amount of such Fronting Commitment, and the assignee's ratable portion of such
Borrowing shall equal (y) the amount such assignee would have funded in respect
of such Borrowing calculated without giving effect to any assignment under which
such assignee was assigned a Fronting Commitment plus (z) the amount of such
Fronting Commitment. After the Administrative Agent's receipt of such funds and
upon fulfillment of the applicable conditions set forth in Article III, the
Administrative Agent will make such funds available to the Borrower. The
Borrower irrevocably directs the Administrative Agent to make available to the
Borrower the portion of any Borrowing to be used to pay amounts owing to the
Vendor, as specified in the related Notice of Borrowing to such account as
notified to the Administrative Agent in the related Notice of Borrowing and to
pay the portion to of any Borrowing to be used to pay interest owing to the
Lenders to the extent permitted hereunder, as specified in the related Notice of
Borrowing, to the Lenders entitled thereto; provided that, if such account is
not with the Administrative Agent such Borrowing shall be deemed to have been
made when the Administrative Agent shall have initiated the transfer of funds
comprising such Borrowing to such account.

     (b) Each Notice of Borrowing shall be irrevocable and binding on the
Borrower. The Borrower shall indemnify each Lender against any loss, cost or
expense incurred by such Lender as a result of any failure to fulfill on or
before the date specified in such Notice of Borrowing for such Borrowing the
applicable conditions set forth in Article III, including (without limitation)
any loss, cost or expense incurred by reason of the liquidation or reemployment
of deposits or other funds acquired by such Lender to fund the Advance to be
made by such Lender as part of such Borrowing when such Advance, as a result of
such failure, is not made on such date. The loss to any Lender attributable to
any such failure shall be deemed to be an amount determined by such Lender to be
equal to the excess, if any, of (i) the amount of interest that such Lender
would pay for a deposit equal to the principal amount of the applicable
Eurodollar Rate Advance not borrowed for the duration of the Interest Period
that would have resulted from such borrowing if the interest rate payable on
such deposit were equal to the Eurodollar Rate for such Interest period, over
(ii) the amount of interest that such Lender would earn on such principal amount
for such period if such Lender were to invest such principal amount for such
period at the interest rate that would be bid by such Lender (or an Affiliate of
such Lender) for dollar deposits from other banks in the eurodollar market at
the commencement
<PAGE>

                                       29



of such period. A certificate as to the amount of such loss, cost or expense,
submitted to the Borrower by such Lender, shall be conclusive and binding for
all purposes, absent manifest error.

     (c) Unless the Administrative Agent shall have received notice from a
Lender that has an applicable Commitment prior to the date of any Borrowing that
such Lender will not make available to the Administrative Agent such Lender's
ratable portion of such Borrowing, the Administrative Agent may assume that such
Lender has made such portion available to the Administrative Agent on the date
of such Borrowing in accordance with subsection (a) of this Section 2.02 and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower on such date a corresponding amount. If and to the extent that such
Lender shall not have so made such ratable portion available to the
Administrative Agent, such Lender and the Borrower severally agree to repay to
the Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is repaid to the Administrative
Agent, at (i) in the case of the Borrower, the interest rate applicable at the
time to Advances comprising such Borrowing and (ii) in the case of such Lender,
the Federal Funds Rate. If such Lender shall repay to the Administrative Agent
such corresponding amount, such amount so repaid shall constitute such Lender's
Advance as part of such Borrowing for purposes of this Agreement.

     (d) The failure of any Lender obligated to make an Advance to make such
Advance to be made by it as part of any Borrowing shall not relieve any other
Lender of its obligation, if any, hereunder to make its Advance on the date of
such Borrowing, but no Lender shall be responsible for the failure of any other
Lender to make any Advance to be made by such other Lender on the date of any
Borrowing.

     SECTION 2.03. Fees. (a) Tranche A Commitment Fee. The Borrower shall pay to
the Administrative Agent for the account of each Lender having a Tranche A
Commitment a commitment fee on the average daily unused portion of each Lender's
Tranche A Commitment from the Tranche A Effective Date in the case of the
Initial Lender and from the effective date specified in the Assignment and
Acceptance pursuant to which it became a Lender in the case of each other such
Lender, until the Tranche A Termination Date at the rate of 1.10 % per annum,
payable in cash on the last day of each Interest Period or, in the event no
Advance is then outstanding, in arrears semi-annually on the last Business Day
of each of June and December, commencing on December 31, 1999, and on the
Tranche A Termination Date.

     (b) Tranche B Commitment Fee. The Borrower shall pay to the Administrative
Agent for the account of each Lender having a Tranche B Commitment a commitment
fee on the average daily unused portion of such Lender's Tranche B Commitment,
from the Tranche B Effective Date, in the case of each Person that is such a
Lender on such date, and from the effective date specified in the Assignment and
Acceptance pursuant to which it became a Lender in the case of each other such
Lender, until the Tranche B Termination Date at
<PAGE>

                                       30



the rate of 1.10% per annum, payable in cash on the last day of each Interest
Period or, in the event no Advance is then outstanding, in arrears semi-annually
on the last Business Day of each of June and December, commencing on June 30,
2001, and on the Tranche B Termination Date.

     (c) Tranche A Facility Fee. The Borrower shall pay to the Administrative
Agent for distribution to the Initial Lender, in cash, on the Tranche A
Effective Date, a one-time facility fee (the "Tranche A Facility Fee") of 1.10%
of the Initial Lender's Tranche A Commitment.

     (d) Tranche B Facility Fee. The Borrower shall pay to the Administrative
Agent for distribution to each Lender that has a Tranche B Commitment, in cash,
on the Tranche B Effective Date, a one-time facility fee (the "Tranche B
Facility Fee") of 1.10% of such Tranche B Lender's Tranche B Commitment, other
than any portion thereof reflecting the transfer of any undrawn portion of such
Lender's Tranche A Commitment on the Tranche A Termination Date.

     (e) Administrative Agent's Fees. The Borrower shall pay to the
Administrative Agent for its own account the fee separately agreed with the
Administrative Agent.

     SECTION 2.04. Termination or Reduction of the Commitments. (a) The Borrower
shall have the right, upon at least 10 Business Days' notice to the
Administrative Agent, to terminate in whole or reduce ratably in part the unused
portions of the respective Commitments of the Lenders; provided that each
partial reduction shall be in the aggregate amount of $3,000,000 or an integral
multiple of $1,000,000 in excess thereof.

     (b) On any date on which a mandatory prepayment of Advances would be
required to be prepaid pursuant to Section 2.08(b), the Commitments shall be
automatically reduced by an amount equal to the excess, if any, of the aggregate
principal amount of the Advances that would be required to be prepaid on such
date if the Commitments were fully drawn (whether or not in fact available for
draw on such date) over the aggregate principal unpaid amount of the Advances
then outstanding.

     SECTION 2.05. Repayment of Advances. (a) Repayment of Tranche A Advances.
The Borrower shall repay to the Administrative Agent for the ratable account of
the Lenders that have made Tranche A Advances the aggregate outstanding
principal amount of the Tranche A Advances in six installments payable on the
last day of every sixth calendar month after the second anniversary of the
Tranche A Effective Date each in an amount equal to the product obtained by
multiplying (i) the unpaid principal amount of such Tranche A Advances
outstanding on the Tranche A Termination Date by (ii) 16-2/3%; provided that the
last such installment shall be in an amount necessary to repay in full the
aggregate then-unpaid principal amount of the Tranche A Advances. Each repayment
shall be applied to the unpaid principal amount of Tranche A Advances ratably
across all Borrowings. At the time of such repayment,
<PAGE>

                                       31



the Borrower also will pay accrued and unpaid interest owing on the principal
amount of the Tranche A Advances then being repaid.

     (b) Repayment of Tranche B Advances. The Borrower shall repay to the
Administrative Agent for the ratable account of the Lenders that have made
Tranche B Advances the aggregate outstanding principal amount of the Tranche B
Advances in seven installments payable on the last day of every sixth calendar
month after the eighteen month anniversary of the Tranche B Effective Date each
in an amount equal to the product obtained by multiplying (a) the unpaid
principal amount of such Tranche B Advances outstanding on the Tranche B
Termination Date by (b) 14.29%; provided that the last such installment shall be
in an amount necessary to repay in full the unpaid principal amount of the
Tranche B Advances. Each repayment shall be applied to the unpaid principal
amount of Tranche B Advances ratably across all Borrowings. At the time of such
repayment, the Borrower also will pay accrued and unpaid interest owing on the
principal amount of the Tranche B Advances then being repaid.

     SECTION 2.06. Interest. (a) Scheduled Interest. Except as otherwise
provided in Section 2.09, the Borrower shall pay interest on the unpaid
principal amount of each Advance owing to each Lender from the date of such
Advance until such principal amount shall be paid in full, at a rate per annum
equal at all times during each Interest Period for such Advance to the sum of
(x) the Eurodollar Rate for such Interest Period for such Advance plus (y)
5.75%, payable in arrears on the last day of such Interest Period and on the
date such Advance shall be paid in full.

     (b) Default Interest. Upon the occurrence and during the continuance of an
Event of Default under Section 6.01(a), the Borrower shall pay interest on (i)
the unpaid principal amount of each Advance owing to each Lender, payable in
arrears on the dates referred to in clause (a) above or Section 2.09(c) or (d)
and on demand, at a rate per annum equal at all times to 2% per annum above the
rate per annum required to be paid on such Advance pursuant to clause (a) above
or Section 2.09(c) or (d) and (ii) to the fullest extent permitted by law, the
amount of any interest, fee or other amount payable hereunder that is not paid

demand, at a rate per annum equal at all times to 2% per annum above the rate
per annum required to be paid on Advances pursuant to clause (a) above.

     SECTION 2.07. Interest Rate Determination. The Administrative Agent shall
give prompt notice to the Borrower and the Lenders of the applicable interest
rate determined by the Administrative Agent for purposes of Section 2.06(a) or
Section 2.09(c) or (d) prior to the commencement of each Interest Period;
provided that any failure by the Administrative Agent to give such notice shall
not affect such applicable interest rate or the Borrower's obligations
hereunder, or give rise to any liability on behalf of the Administrative Agent.

                                       32



     SECTION 2.08. Prepayments. (a) Optional Prepayments. The Borrower may, upon
at least 10 Business Days' notice to the Administrative Agent stating the
proposed date and aggregate principal amount of the prepayment, and if such

If the Borrower shall not have made a prepayment pursuant to this subsection
because of the proviso hereto and shall not have fulfilled the conditions set
forth in such proviso within the period specified therein, it shall make the

<PAGE>

                                       34



the "Securities Act"), (B) under Section 4(2) of the Securities Act or (C) in
accordance with the registration and delivery requirements of Section 5 of the
Securities Act, prepay an aggregate principal amount of the Advances comprising
part of the same Borrowings equal to 50% of the Lenders' Pro Rata Portion of
such Net Cash Proceeds (or, if less, the aggregate principal amount of all
Advances).

     (v) Excess Cash Flow. The Borrower shall, within five Business Days of each
date upon which the Borrower is required to furnish to the Lenders its annual
financial statements pursuant to Section 5.03(d), deposit into an escrow account
(the terms of which shall be reasonably satisfactory to the Administrative
Agent) an amount equal to 50% of the Borrower's Excess Cash Flow for the
Borrower's fiscal year reflected in such report (for such fiscal year, the
"Excess Cash Flow Amount"). Upon the last day of the Interest Period during
which such deposit was made, the Borrower shall prepay an aggregate principal
amount of the Advances equal to the Lenders' Pro Rata Portion of such Excess
Cash Flow Amount (or, if the outstanding principal amount of the Advances is

day, the aggregate principal amount of all Advances). Any amounts remaining in
such escrow amount after such prepayment shall be released to the Borrower
immediately following such prepayment.

     (vi) Notice. The Borrower shall give the Administrative Agent at least five
Business Days' prior written notice of (A) each prepayment required by this
Section 2.08(b) and (B) the application of any Net Cash Proceeds pursuant to any

made.

     (c) Mechanics of Prepayments. All prepayments under this Section 2.08 shall
be made together with accrued interest to the date of such prepayment on the
principal amount prepaid and together with any amounts owing to the Lenders
pursuant to Section 8.04(c) in respect of such prepayment. Any prepayment of
Advances pursuant to this Section 2.08 shall be applied to the installments
thereof in inverse order of maturity, ratably across all Advances being so
prepaid. All prepayments under this Section 2.08 shall be made ratably with
prepayments to lenders under the other Permitted Loan Agreements (as defined in
the Intercreditor Agreement), in proportion with the outstanding principal
amounts owing by the Borrower under the Permitted Loan Agreements .

     SECTION 2.09. Increased Costs, Etc. (a) If, due to either (i) the
introduction of or any change (other than any change by way of imposition or
increase of reserve requirements included in the Eurodollar Rate Reserve
Percentage) in or in the interpretation of any law or regulation or (ii) the
compliance with any guideline or request from any central bank or other
governmental authority (whether or not having the force of law), there shall be
any increase in the cost to any Lender of agreeing to make or of making, funding
or maintaining Advances
<PAGE>

                                       35



(excluding for purposes of this Section 2.09 any such increased costs resulting
from (A) Taxes or Other Taxes (as to which Section 2.11 shall govern) or (B)
changes in the basis of taxation of overall net income or overall gross income
by the jurisdiction or state under the laws of which such Lender is organized or
has its Lending Office or any political subdivision thereof), then the Borrower
shall from time to time, upon demand by such Lender (with a copy of such demand
to the Administrative Agent), pay to the Administrative Agent for the account of
such Lender additional amounts sufficient to compensate such Lender for such
increased cost; provided that a Lender claiming additional amounts under this
Section 2.09(a) agrees to use reasonable efforts (consistent with its internal
policy and legal and regulatory restrictions) to designate a different Lending
Office if the making of such a designation would avoid the need for, or reduce
the amount of, such increased cost that may thereafter accrue and would not, in
the reasonable judgment of such Lender be otherwise disadvantageous to such
Lender. If any Lender becomes entitled to claim any additional amounts pursuant
to this Section 2.09(a), it will promptly notify the Borrower (with a copy of
such notice to the Administrative Agent) of the event by reason of which it has
become so entitled and provide a detailed calculation of the amount to be paid;
provided that no Lender shall be required to disclose in connection with such
calculation any information that it deems to be proprietary or confidential,
including, without limitation, any allocation of internal costs. A certificate
as to the amount of such increased cost, submitted to the Borrower by such
Lender, shall be conclusive and binding for all purposes, absent manifest error.

     (b) If any Lender determines that compliance with any law or regulation or
any guideline or request from any central bank or other governmental authority
(whether or not having the force of law) affects or would affect the amount of
capital required or expected to be maintained by such Lender or any corporation
controlling such Lender and that the amount of such capital is increased by or
based upon the existence of such Lender's commitment to lend hereunder then,
upon demand by such Lender (with a copy of such demand to the Administrative
Agent), the Borrower shall pay to the Administrative Agent for the account of
such Lender, from time to time as specified by such Lender, additional amounts
sufficient to compensate such Lender in the light of such circumstances, to the
extent that such Lender reasonably determines such increase in capital to be
allocable to the existence of such Lender's commitment to lend hereunder;
provided that, before making any such demand, such Lender will use reasonable
efforts (consistent with its internal policy and legal and regulatory
restrictions) to designate a different Lending Office if the making of such a
designation would allow such Lender or its Lending Office to continue to perform
its obligations to make Advances or to continue to fund or maintain Advances and
would not, in the judgment of such Lender, be otherwise disadvantageous to such
Lender. If any Lender becomes entitled to claim any additional amounts pursuant
to this Section 2.09(b), it will promptly notify the Borrower (with a copy of
such notice to the Administrative Agent) of the event by reason of which it has
become so entitled and provide a detailed calculation of the amount to be paid;
provided that no Lender shall be required to disclose in connection with such
calculation any information that it deems to be proprietary or confidential,
including, without limitation, any allocation of internal costs. A
<PAGE>

                                       36



certificate as to such amounts submitted to the Borrower by such Lender shall be
conclusive and binding for all purposes, absent manifest error.

     (c) If, with respect to any Advances, a majority in interest of the Lenders
participating in such Advances notify the Administrative Agent that the
Eurodollar Rate for any Interest Period for such Advances will not adequately
reflect the cost to such Lenders of making, funding or maintaining their
Advances for such Interest Period, the Administrative Agent shall forthwith so
notify the Borrower, whereupon (i) each such Advance will automatically, on the
last day of the then existing Interest Period therefor, cease to bear interest
pursuant to Section 2.06(a) and from such date bear interest at a rate per annum
equal at all times to the sum of (A) the Base Rate in effect from time to time
plus (B) 6.25%, payable in arrears semi-annually on the last day of December and
June until the Administrative Agent shall notify the Borrower that such Lenders
have determined that the circumstances causing such suspension no longer exist
and (ii) the Borrower shall pay interest on the unpaid principal amount of each
Advance made after the giving of such notice by the Required Lenders from the
date of such Advance until the earlier of (A) the payment in full of such
Advance and (B) the date upon which the Administrative Agent has notified the
Borrower that such Lenders have determined that the circumstances causing such
suspension no longer exist, at a rate per annum equal to the actual cost
incurred by the Lenders in making such Advance plus 6.25%, payable in arrears
semi-annually on the last day of December and June. A certificate as to the rate
referred to in clause (ii) above submitted to the Borrower by such Lenders shall
be conclusive and binding for all purposes, absent manifest error.

     (d) Notwithstanding any other provision of this Agreement, if the
introduction of or any change in or in the interpretation of any law or
regulation shall make it unlawful, or any central bank or other governmental
authority shall assert that it is unlawful, for any Lender or its Lending Office
to perform its obligations hereunder to make Advances or to continue to fund or
maintain Advances hereunder, then, on notice thereof and demand therefor by the
Required Lenders to the Borrower through the Administrative Agent, (i) each
Advance will automatically, on such demand, cease to bear interest pursuant to
Section 2.06(a) and from such demand bear interest at a rate per annum equal at
all times to the sum of (A) the Base Rate in effect from time to time plus (B)
6.25%, payable in arrears semi-annually on the last day of each December and
June until the Administrative Agent shall notify the Borrower that such Lender
has determined that the circumstances causing such suspension no longer exist,
and (ii) the Borrower shall pay interest on the unpaid principal amount of each
Advance made after the giving of such notice by the Required Lenders from the
date of such Advance until the earlier of (A) the payment in full of such
Advance and (B) the date upon which the Administrative Agent has notified the
Borrower that such Lenders have determined that the circumstances causing such
suspension no longer exist, at a rate per annum equal to the actual cost
incurred by the Lenders in making such Advance plus 6.25%, payable in arrears
semi-annually on the last day of December and June; provided that, before making
any such demand, such Lender will use reasonable efforts (consistent with its
internal policy and legal and regulatory restrictions) to designate a different
Lending Office if the making of such a designation would allow such Lender or
its Lending

                                       37



Office to continue to perform its obligations to make Advances or to continue to
fund or maintain Advances and would not, in the judgment of such Lender, be
otherwise disadvantageous to such Lender. A certificate as to the rate referred
to in clause (ii) above submitted to the Borrower by such Lenders shall be
conclusive and binding for all purposes, absent manifest error.

     SECTION 2.10. Payments and Computations. (a) The Borrower shall make each
payment hereunder and under the Notes issued hereunder not later than 11:00 A.M.
(New York City time) on the day when due in U.S. dollars to the Administrative
Agent at the Administrative Agent's Account in same-day funds. The
Administrative Agent will promptly thereafter cause to be distributed like funds
relating to the payment of principal or interest or fees ratably (other than
amounts payable pursuant to Section 2.09, 2.11 or 8.04(c)) to the Lenders
entitled thereto for the account of their respective Lending Offices, and like
funds relating to the payment of any other amount payable to any Lender to such
Lender for the account of its Lending Office, in each case to be applied in
accordance with the terms of this Agreement. Upon its acceptance of an
Assignment and Acceptance and recording of the information contained therein in
the Register pursuant to Section 8.07(d), from and after the effective date
specified in such Assignment and Acceptance, the Administrative Agent shall make
all payments hereunder and under the Notes issued hereunder in respect of the
interest assigned thereby to the Lender assignee thereunder, and the parties to
such Assignment and Acceptance shall make all appropriate adjustments in such
payments for periods prior to such effective date directly between themselves
and the Borrower shall have no further obligation to such assignee with respect
to such adjustments.

     (b) Promptly on request by any Lender, the Borrower will deliver to such
Lender a Note payable to the order of such Lender.

     (c) All computations of interest based on the Base Rate shall be made by
the Administrative Agent on the basis of a year of 365 or 366 days, as the case
may be, and all computations of other interest and of fees shall be made by the
Administrative Agent on the basis of a year of 360 days, in each case for the
actual number of days (including the first day but excluding the last day)
occurring in the period for which such interest or fees are payable. Each
determination by the Administrative Agent of an interest rate hereunder shall be
conclusive and binding for all purposes, absent manifest error.

     (d) Whenever any payment hereunder or under the Notes issued hereunder
shall be stated to be due on a day other than a Business Day, such payment shall
be made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of payment of interest or commitment
fee, as the case may be; provided that, if such extension would cause payment of
interest on or principal of Advances to be made in the next following calendar
month, such payment shall be made on the next-preceding Business Day.

                                       38



     (e) Unless the Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due to the Lenders hereunder
that the Borrower will not make such payment in full, the Administrative Agent
may assume that the Borrower has made such payment in full to the Administrative
Agent on such date and the Administrative Agent may, in reliance upon such
assumption, cause to be distributed to each Lender on such due date an amount
equal to the amount then due such Lender. If and to the extent the Borrower
shall not have so made such payment in full to the Administrative Agent, each
Lender shall repay to the Administrative Agent forthwith on demand such amount
distributed to such Lender together with interest thereon, for each day from the
date such amount is distributed to such Lender until the date such Lender repays
such amount to the Administrative Agent, at the Federal Funds Rate.

     (f) The obligation of the Borrower to make any payment under this Agreement
or any other Loan Document, including without limitation payments of principal,
interest, fees, costs and expenses due in accordance with the terms of the Loan
Documents, shall be unconditional and absolute, irrespective among other things
of the following:

          (i) any set-off, counterclaim, recoupment, deduction, abatement,
     suspension, diminution, reduction, defense or other right that the Borrower
     may have against the Vendor at any time for any reason whatsoever arising
     under or pursuant to the Supply Agreement or otherwise relating to the
     purchase of goods, equipment, other property or services from or by the
     Vendor;

          (ii) any defect in the condition, design, operation or fitness for use
     of, or any damage to or loss or destruction of, any equipment or material
     provided by the Vendor;

          (iii) any actual or alleged default by the Vendor or any other Person
     under the Supply Agreement; or

          (iv) any other fact or circumstance relating to the Supply Agreement.

     SECTION 2.11. Taxes. (a) Any and all payments by the Borrower hereunder or
under the Notes issued hereunder shall be made, in accordance with Section 2.10,
free and clear of and without deduction for any and all present or future taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, excluding, in the case of each Lender and the Administrative
Agent, taxes that are imposed on its overall net income by the United States and
taxes that are imposed on its overall net income (and franchise taxes imposed in
lieu thereof) by the state or foreign jurisdiction under the laws of which such
Lender or the Administrative Agent (as the case may be) is organized or any
political subdivision thereof and, in the case of each Lender, taxes that are
imposed on its overall net income (and franchise taxes imposed in lieu thereof)
by the state or foreign jurisdiction of such Lender's Lending Office or any
political subdivision thereof (all such non-excluded taxes, levies, imposts,
deductions,
<PAGE>

                                       39



charges, withholdings and liabilities in respect of payments hereunder or under
the Notes being hereinafter referred to as "Taxes"). If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under any Note to any Lender or the Administrative Agent, (i) the
sum payable shall be increased as may be necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 2.11) such Lender or the Administrative Agent (as the case
may be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law.

     (b) In addition, the Borrower shall pay any present or future stamp,
documentary, excise, property or similar taxes, charges or levies that arise
from any payment made hereunder or under the Notes or from the execution,
delivery or registration of, performing under, or otherwise with respect to,
this Agreement, the Notes or the other Loan Documents (hereinafter referred to
as "Other Taxes").

     (c) The Borrower shall indemnify each Lender and the Administrative Agent
for and hold it harmless against the full amount of Taxes or Other Taxes
(including without limitation taxes of any kind imposed by any jurisdiction on
amounts payable under this Section 2.11) imposed on or paid by such Lender or
the Administrative Agent (as the case may be) and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto.
This indemnification shall be made within 30 days from the date such Lender or
the Administrative Agent (as the case may be) makes written demand therefor.

     (d) Within 60 days after the date of any payment of Taxes, the Borrower
shall furnish to the Administrative Agent, at its address referred to in Section
8.02, the original or a certified copy of a receipt evidencing such payment. In
the case of any payment hereunder or under the Notes by or on behalf of the
Borrower through an account or branch outside the United States or by or on
behalf of the Borrower by a payor that is not a United States person, if the
Borrower determines that no Taxes are payable in respect thereof, the Borrower
shall furnish, or shall cause such payor to furnish, to the Administrative
Agent, at such address, an opinion of counsel acceptable to the Administrative
Agent stating that such payment is exempt from Taxes. For purposes of this
subsection (d) and subsection (e), the terms "United States" and "United States
person" shall have the meanings specified in Section 7701 of the Internal
Revenue Code or (in the case of a Lender that has certified in writing to the
Administrative Agent that it is not a "bank" as defined in Section 881(c)(3)(A)
of the Internal Revenue Code) form W-8 (and, if such Lender delivers a form W-8,
a certificate representing that such Lender is not a "bank" for purposes of
Section 881(c) of the Internal Revenue Code, is not a 10-percent shareholder
(within the meaning of Section 871(h)(3)(B) of the Internal Revenue Code) of the
Borrower and is not a controlled foreign corporation related to the Borrower
(within the meaning of Section 864(d)(4) of the Internal Revenue Code)), as
appropriate, or any successor or other form prescribed by the Internal Revenue
Service, certifying that such Lender is exempt from or entitled to a reduced
rate
<PAGE>

                                       40



of United States withholding tax on payments pursuant to this Agreement or the
Notes or, in the case of a Lender providing a form W-8, certifying that such
Lender is a foreign corporation, partnership, estate or trust. If the forms
provided by a Lender at the time such Lender first becomes a party to this
Agreement indicates a United States interest withholding tax rate in excess of
zero, withholding tax at such rate shall be considered excluded from Taxes
unless and until such Lender provides the appropriate form certifying that a
lesser rate applies, whereupon withholding tax at such lesser rate only shall be
considered excluded from Taxes for periods governed by such form; provided that,
if at the date of the Assignment and Acceptance pursuant to which a Lender
becomes a party to this Agreement, the Lender assignor was entitled to payments
under subsection (a) in respect of United States withholding tax with respect to
interest paid at such date, then, to such extent, the term Taxes shall include
(in addition to withholding taxes that may be imposed in the future or other
amounts otherwise includable in Taxes) United States withholding tax, if any,
applicable with respect to the Lender assignee on such date. If any form or
document referred to in this subsection (d) requires the disclosure of
information, other than information necessary to compute the tax payable and
information required on the date hereof by Internal Revenue Service form 1001,
4224 or W-8 (or the related certificate described above), that the Lender
reasonably considers to be confidential, the Lender shall give notice thereof to
the Borrower and shall not be obligated to include in such form or document such
confidential information.

     (e) For any period with respect to which a Lender has failed to provide the
Borrower with the appropriate form described in Section 2.11(d) (other than if
such failure is due to a change in law occurring subsequent to the date on which
a form originally was required to be provided, or if such form otherwise is not
required under subsection (d) above), such Lender shall not be entitled to
indemnification under Section 2.11(a) or (c) with respect to Taxes imposed by
the United States by reason of such failure; provided that should a Lender
become subject to Taxes because of its failure to deliver a form required
hereunder, the Borrower shall take such steps as the Lender shall reasonably
request to assist the Lender to recover such Taxes.

     SECTION 2.12. Sharing of Payments, Etc. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the Advances owing to it (other than
pursuant to Section 2.09, 2.11 or 8.04(c)) in excess of its ratable share of
payments on account of the Advances obtained by all the Lenders, such Lender
shall forthwith purchase from the other Lenders such participations in the
Advances owing to them as shall be necessary to cause such purchasing Lender to
share the excess payment ratably with each of them; provided that if all or any
portion of such excess payment is thereafter recovered from such purchasing
Lender, such purchase from each Lender shall be rescinded and such Lender shall
repay to the purchasing Lender the purchase price to the extent of such recovery
together with an amount equal to such Lender's ratable share (according to the
proportion of (a) the amount of such Lender's required repayment to (b) the
total amount so recovered from the purchasing Lender) of any interest or other
amount paid or payable by the purchasing Lender in respect of the total amount
so recovered. The Borrower agrees that any
<PAGE>

                                       41



Lender so purchasing a participation from another Lender pursuant to this
Section 2.12 may, to the fullest extent permitted by law, exercise all its
rights of payment (including the right of set-off) with respect to such
participation as fully as if such Lender were the direct creditor of the
Borrower in the amount of such participation. With respect to any reduction or
termination of Commitments pursuant to Section 2.04, the reduction or
termination of the Commitments shall be made ratably among the Commitments of
all Lenders outstanding at the time of such reduction or termination. With
respect to any repayment or prepayment made by the Borrower hereunder other than
scheduled amortization pursuant to Section 2.05, such repayment or prepayment
shall be distributed ratably among all Lenders in proportion with the principal
amount of the Advances held by each such Lender outstanding at the time of such
repayment or prepayment. With respect to any repayment of scheduled amortization
made by the Borrower hereunder pursuant to Section 2.05, such repayments shall
be distributed ratably among all Lenders of the relevant tranche in proportion
with the principal amount of the Advances of such tranche held by each such
Lender of outstanding at the time of such repayment or prepayment.

     SECTION 2.13. Use of Proceeds. The proceeds of the Advances shall be
available to the Borrower and its Subsidiaries, directly or indirectly, solely
(a) to make Back-to-Back Loans that shall be used by Operating Subsidiaries to
purchase telecommunications equipment, software, engineering and other services
pursuant to or in accordance with the Supply Agreement and subject to the
limitations set forth therein for the purpose of planning, constructing,
operating and maintaining Networks in the Core Territories, (b) to pay interest
payable to the Lenders on each interest payment date occurring on or prior to
the first anniversary of the Tranche A Effective Date and (c) to pay fees
payable pursuant to Section 2.03 and expenses payable pursuant to Section
8.04(a)(i)(A) and (B), in each case with respect to the Lenders. The proceeds of
all Advances to be used as described in clause (a) of the preceding sentence
shall be paid directly to the financial institution providing Back-to-Back Loans
and the proceeds of such Back-to-Back Loans made to Operating Subsidiaries in
Argentina, Brazil and Peru shall at all times be held in Blocked Accounts until
disbursed to pay invoices under the Supply Agreement.

     SECTION 2.14. First Eurodollar Method and Second Eurodollar Method. The
First Eurodollar Method shall be applicable at all times until such time as the
Second Eurodollar Method becomes applicable. If there is a Lender in addition to
or other than the Initial Lender (other than an Affiliate of the Initial Lender)
and the Administrative Agent at the direction of any Lender shall have notified
the Borrower that the Second Eurodollar Method shall be applicable, the Second
Eurodollar Method shall become applicable immediately as of the date of such
notice for all new Advances made as of and following the date of such notice.
After becoming applicable, the Second Eurodollar Method shall remain applicable
at all times thereafter.

     SECTION 2.15. Redistribution of Payments. In the event that a repayment
under Section 2.05 or a prepayment under Section 2.08 is required to be
redistributed by the Lenders to the lenders (the "Other Lenders") under another
Permitted Loan Agreement (as defined in the
<PAGE>

                                       42



Intercreditor Agreement) pursuant to Section 4.2 or 4.3 of the Intercreditor
Agreement, (i) the Borrower authorizes the Lenders to act as its agent in
connection with such redistribution and make such redistribution to the Other
Lenders on its behalf and acknowledges that any amount so redistributed shall be
deemed not to have been paid by the Borrower to the Lenders in their capacity as
Lenders hereunder and (ii) the Lenders agree to act as agent for the Borrower in
connection with such redistribution and agree to make such redistribution to the
Other Lenders on its behalf. In the event that a repayment or prepayment made by
the Borrower pursuant to another Permitted Loan Agreement to the Other Lenders
party thereto is required to be redistributed by such Other Lenders pursuant to
Section 4.2 or 4.3 of the Intercreditor Agreement, the Lenders acknowledge that
any amount so redistributed (I) shall have been paid by the Other Lenders acting
as agent for the Borrower in connection with such redistribution, (II) shall be
deemed to have been paid by the Borrower to the Lenders in respect of the
Advances pursuant to Section 2.05 or 2.08, as the case may be, and (III) shall
be allocated among the Lenders in accordance with Section 2.12.

     Company Subsidiary of the Borrower during the period when any Advances
     shall be outstanding.

          (c) Each Loan Party has full corporate power and authority to enter

                                       50



          (f) Except as otherwise described on Schedule 4.01 (f) as amended from
     time to time pursuant to Section 5.03 (u) no authorization or approval or
     other action by, and no notice to or filing with, any governmental
     authority or any other third party is required for (i) the due execution,
     delivery, recordation, filing or performance by any Loan Party of this
     Agreement, the Notes or any other Loan Document to which it is or is to be
     a party or for the consummation of the transactions contemplated hereby and
     thereby, (ii) the grant of the Liens granted by any Loan Party pursuant to
     this Agreement, the Security Agreements, the Blocked Account Letter
     Agreements and the Notes (including to the extent permitted by applicable
     law and subject to Permitted Liens and Shared Liens the first-priority
     nature thereof) other than Permitted Liens and Shared Liens and (iii) the
     exercise by the Administrative Agent, the Collateral Agent or any Lender of
     its rights under this Agreement, the Notes or any other Loan Document or of
     the remedies in respect of the collateral granted pursuant to the Security
     Agreements.

          (g) This Agreement, the Notes and each other Loan Document to which it
     is a party have been duly executed and delivered by the Borrower and, when
     executed and delivered hereunder, will constitute legal, valid and binding
     obligations of the Borrower and each of its Subsidiaries that is a party
     thereto, enforceable against the Borrower and such Subsidiaries in
     accordance with their respective terms except as such enforceability may be
     limited by (i) applicable bankruptcy, insolvency, liquidation, fraudulent
     conveyance, reorganization, concordato, moratorium or similar laws now or
     hereafter in effect affecting the enforcement of creditors' rights
     generally and (ii) general principles of equity (regardless of whether such
     enforceability is considered in a proceeding at law or in equity).

          (h) The balance sheet of the Borrower as at September 30, 1999 and the
     related statement of income and cash flows of the Borrower for the three
     month period then ended, copies of which have been furnished to each
     Lender, fairly present in all material respects (subject to year-end audit
     adjustments) the financial condition of the Borrower as at such date and
     the results of operations of the Borrower for the period ended on such
     date, all in accordance with generally accepted accounting principles
     applied on a consistent basis. The Consolidated forecasted balance sheets,
     income statements and cash flow statements of the Borrower and its
     Subsidiaries delivered to the Lenders in connection with the Project were
     prepared in good faith on the basis of the assumptions stated therein,
     which assumptions the Borrower believes were fair in the light of
     conditions existing at the time of delivery of such forecasts, and
     represented, at the time of delivery, the Borrower's best estimate of its
     future financial performance, it being understood that nothing set forth in
     such Consolidated forecasted balance sheets, income statements and cash
     flow statements shall be construed as a representation, warranty, covenant,
     undertaking, guaranty or assurance by the Borrower or any of its
     Subsidiaries as to the future financial or business performance of the
     Borrower and its
<PAGE>

                                       51



     Subsidiaries and that the forward-looking statements contained in such
     Consolidated forecasted balance sheets, income statements and cash flow
     statements involve known and unknown risks, contingencies, uncertainties
     and other factors that may cause the actual results, events or developments
     pertaining to the Borrower and its Subsidiaries to be materially and
     adversely different from any future results, events or developments
     contemplated, expressed or implied by such Consolidated forecasted balance
     sheets, income statements and cash flow statements. Since September 30,
     1999, there has been no Material Adverse Change.

          (i) No information, exhibit or report furnished in writing by (or on
     behalf of) the Borrower to the Administrative Agent, the Collateral Agent
     or any Lender in connection with the negotiation of the Loan Documents or
     pursuant to the terms of the Loan Documents contained at the time when
     furnished any untrue statement of material fact or omitted to state a
     material fact necessary to make the statements made therein (taken as a
     whole) not misleading.

          (j) Except as otherwise described on Schedule 3.01(a)(i), there is no
     pending or, to the best of the Borrower's knowledge, threatened action,
     suit, investigation, litigation or proceeding, including without limitation
     any Environmental Action, affecting the Borrower or any of its Subsidiaries
     before any court, governmental agency or arbitrator that (i) could be
     reasonably likely to have a Material Adverse Effect or (ii) purports to
     affect the legality, validity or enforceability of any Loan Document or the
     consummation of the transactions contemplated hereby or thereby, and there
     has been no material adverse change in the status, or financial effect on
     the Borrower or any of its Subsidiaries, of the Disclosed Litigation from
     that described on Schedule 3.01(a)(i) hereto.

          (k) The Borrower is not engaged in the business of extending credit
     for the purpose of purchasing or carrying Margin Stock, and no proceeds of
     any Advance will be used to purchase or carry any Margin Stock or to extend
     credit to others for the purpose of purchasing or carrying any Margin
     Stock.

          (l) The operations and properties of the Borrower and Subsidiaries
     comply in all material respects with all applicable Environmental Laws and
     Environmental Permits, except where the failure to be in such compliance
     could not reasonably be expected to have a Material Adverse Effect.

          (m) The Borrower and each of its Subsidiaries has filed, has caused to
     be filed or has been included in all tax returns (national, departmental,
     local, municipal and foreign) required to be filed and has paid or caused
     to be paid all taxes, assessments, fees and other charges shown thereon to
     be due, together with applicable interest and penalties, other than the
     payment of any taxes, assessment, fees or other charges (i) the
<PAGE>

                                       52



     nonpayment of which would not have a Material Adverse Effect or (ii) that
     are being contested in good faith and by proper proceedings and for which
     appropriate reserves are being maintained.

          (n) The obligations of the Borrower and each of its Subsidiaries under
     this Agreement, the Notes and each other Loan Document to which it is or is
     to be a party constitute direct, unconditional and unsubordinated
     obligations of the Borrower.

     except for Liens created pursuant to the Loan Documents.

          (p) The Borrower and its Subsidiaries have valid and uncontested legal
     title to and are the beneficial owners of the Collateral and all of their
     respective other material properties and assets, free and clear of all
     Liens other than Permitted Liens and the Liens created pursuant to the Loan
     Documents.

          (q) The Borrower and each of its Subsidiaries is in compliance in all
     material respects with all applicable laws, ordinances, rules, regulations,
     and requirements of all governmental authorities (including without
     limitation certificates, permits, franchises and other governmental
     authorizations necessary to the ownership of its respective properties or
     to the conduct of its respective business, Environmental Laws and laws with
     respect to social security and pension fund obligations), except in each
     case to the extent where such failure to comply would not have a Material
     Adverse Effect.

          (r) Neither the Borrower nor any of its Subsidiaries is an "investment
     company", or an "affiliated person" of, or "promoter" or "principal
     underwriter" for, an "investment company", as such terms are defined in the
     Investment Company Act of 1940, as amended. Neither the making of any
     advance under this Agreement nor the application of the proceeds or
     repayment thereof by the Borrower, nor the consummation of the other
     transactions contemplated hereby, shall violate any provision of such Act
     or any rule, regulation or order thereunder.

          (s) The Borrower is, individually and together with its Subsidiaries,

          (u) Neither the Borrower nor any of its Subsidiaries has any patents,
     trademarks, trade names, service marks or copyrights that are material to
     the conduct of its business.

          (v) Set forth on Schedule 4.01(v) hereto, as amended from time to time
     pursuant to Section 5.03(u), is a complete and accurate list of (i) all

     be, is in full force and effect and is binding upon and enforceable against
     the Borrower or its Subsidiary, as the case may be, in accordance with its
     terms except as such enforceability may be limited by (i) applicable
     bankruptcy, insolvency, liquidation, fraudulent conveyance, reorganization,
     concordato, moratorium or similar laws now or hereafter in effect affecting
     the enforcement of creditors' rights generally, and (ii) general principles
     of equity (regardless of whether such enforceability is considered in a
     proceeding at law or in equity), and there exists no default under any
     Material Contract by the Borrower or its Subsidiaries, as the case may be,
     which default could reasonably be expected to have a Material Adverse
     Effect.

          (y) Set forth on Schedule 4.01(y) hereto, as amended from time to time

     pursuant to Section 5.03(u), is a complete and accurate list of all
     insurance policies naming the Lenders and the other Secured Creditors as

     similar properties in the same general areas in which the Borrower or such
<PAGE>

                                       54



     Subsidiary operates and such insurance is sufficient to cover the risks
     associated with the conduct of the Borrower's or such Subsidiary's business
     and the Project.

          (aa) The activities of the Borrower's Subsidiaries contemplated by the
     Project and this Agreement are commercial in nature rather than
     governmental or public. The Borrower's Subsidiaries are not entitled to any
     right of immunity on the grounds of sovereignty with respect to such
     activities in any legal action or proceeding to enforce, or collect upon,
     or otherwise arising out of or relating to this Agreement, any of the other
     Loan Documents or Material Contracts.

          (bb) As of the date hereof, there is no tax, levy, impost, deduction,
     charge or withholding imposed, levied or made by or in any Core Territory
     or New York or any political subdivision or taxing authority thereof or
     therein (i) on or by virtue of the execution, delivery, performance,
     enforcement or admissibility into evidence of this Agreement or any of the
     other Loan Documents or (ii) on any payment to be made by the Borrower's
     Subsidiaries pursuant to this Agreement or any of the other Loan Documents,
     except that (A) all payments made under a Guaranty granted by the Operating

     that is a resident of a country that does not tax income or taxes it at a
     maximum rate of 20%) or such lower rate as provided in an applicable tax
     treaty between Brazil and another country, and pursuant to Brazilian tax
     laws, a Brazilian Loan Party may pay such additional amounts as will result
     in receipt by the applicable payee of such amounts as would have been
     received by them had no such withholding been required; (B) (i) any
     interest payments made by an Argentine Loan Party may be subject to
     Argentine withholding tax at the current rate of 35%; (ii) a court tax of
     up to 3% of the amount in controversy imposed with respect to the
     institution of any judicial proceeding to enforce any claim in the City of
     Buenos Aires or in any other jurisdiction in Argentina; and (iii) each
     Chattel Mortgage registered pursuant to the Master Chattel Mortgage
     Agreement will be subject to registration fee of 0.2% of the amount secured
     by such Chattel Mortgage (in the case of the Province of Buenos Aires), and
     to a stamp tax at a rate of 1.0% (subject to the provisions of the Fiscal
     Code of the Province of Buenos Aires) on the amount secured (in the case of
     the Province of Buenos Aires); (C) in the case of Colombia, the value of
     the foreclosure in any auction in Colombia is subject to a 3% tax and the

                                EVENTS OF DEFAULT

     SECTION 6.01. Events of Default. If any of the following events ("Events of
Default") shall occur and be continuing:

          (a) the Borrower shall fail to pay any principal of any Advance when
     the same becomes due and payable or the Borrower shall fail to pay any
     interest on any Advance or make any other payment of fees or other amounts
     payable under this Agreement or any Note within three days after the same
     becomes due and payable; or

          (b) any representation or warranty made by any Loan Party (or any of
     its officers) in connection with any Loan Document shall prove to have been
     incorrect in any material respect when made; provided that, if such
     inaccuracy is capable of remedy and is in respect of any representation and
     warranty other than those contained in Sections 4.01(a), (b), (c), (d),
     (g), (h), (i), (j), (k), (n) and (y), such inaccuracy shall continue
     unremedied for a period of 10 days; or

          (c) either:

               (i) the Borrower shall fail to perform or observe any term,
          covenant or agreement contained in Section 2.13, 5.01(e), (f), (k) or
          (n), 5.02 or 5.04, or

               (ii) the Borrower shall fail to perform or observe any other
          covenant in this Agreement or any Loan Party shall fail to perform or
          observe any other covenant to be performed or observed by it in any
          other Loan Document, and in any case such failure shall continue
          unremedied for a period of 30 days; or

          (d) any Security Agreement, once executed and delivered, shall cease
     to provide to the Collateral Agent and the Lenders, with the Liens,
     priority, security interests, rights, titles, interests, remedies, powers
     and privileges intended to be created thereby; or

          (e) any of the following shall occur:

               (i) any License or portion thereof shall become invalid or
          unenforceable or shall terminate or not be renewed and, with respect
          to any such portion, such occurrence is reasonably likely to have a
          material adverse effect on the ability of the Borrower to perform its
          payment obligations under the Loan Documents;
<PAGE>

                                       80



               (ii) any rights of the Borrower or any of its Subsidiaries
          thereunder shall be changed and such change is reasonably likely to
          have a material adverse effect on the ability of the Borrower to
          perform its payment obligations under the Loan Documents;

               (iii) any proceeding shall be commenced with the intention of
          revoking the Licenses or a portion thereof that (A) has a reasonable
          likelihood of succeeding and could reasonably be expected to prevent
          the Borrower from operating a material portion of its Network or does
          succeed in revoking all of the Licenses or (B) could reasonably be
          expected to result in or which actually results in, a material adverse
          effect on the ability of the Borrower to perform its payment
          obligations under the Loan Documents; or

               (iv) any Core Territory shall impose any obligation on the
          Borrower or any of its Subsidiaries in respect of any License that is
          reasonably likely to have a material adverse effect on the ability of
          the Borrower to perform its payment obligations under the Loan
          Documents; or

          (f) either:

               (i) the Borrower or any of its Subsidiaries shall fail to pay (A)
          any principal of or premium or interest on or any other amount payable
          in respect of any Debt or (B) any principal of any Subordinated Debt
          or Intercompany Mirror Subordinated Debt, in each case that is
          outstanding in a principal or notional amount of at least $5,000,000
          in the aggregate (but excluding Debt outstanding hereunder) of the
          Borrower or such Subsidiary (as the case may be), when the same
          becomes due and payable (whether by scheduled maturity, required
          prepayment, acceleration, demand or otherwise), and such failure shall
          continue after the applicable grace period, if any, specified in the
          agreement or instrument relating to such Debt; or any other event
          shall occur or condition shall exist under any agreement or instrument
          relating to any such Debt and shall continue after the applicable
          grace period, if any, specified in such agreement or instrument, if
          the effect of such event or condition is to accelerate, or to permit
          the acceleration of, the maturity of such Debt; or any such Debt shall
          be declared to be due and payable, or required to be prepaid or
          redeemed (other than by a regularly scheduled required prepayment or
          redemption), purchased or defeased, or an offer to prepay, redeem,
          purchase or defease such Debt shall be required to be made, in each
          case prior to the stated maturity thereof; or

               (ii) the Parent shall fail to pay any principal of or premium or
          interest on or any other amount payable in respect of any Debt that is
          outstanding in a principal or notional amount of at least $5,000,000
          in the aggregate, when the
<PAGE>

                                       81



          same becomes due and payable (whether by scheduled maturity, required
          prepayment, acceleration, demand or otherwise), and such failure shall
          continue after the applicable grace period, if any, specified in the
          agreement or instrument relating to such Debt; or any other event
          shall occur or condition shall exist under any agreement or instrument
          relating to any such Debt and shall continue after the applicable
          grace period, if any, specified in such agreement or instrument, if
          the effect of such event or condition is to accelerate the maturity of
          such Debt; or any such Debt shall be declared to be due and payable,
          or required to be prepaid or redeemed (other than by a regularly
          scheduled required prepayment or redemption), purchased or defeased,
          or an offer to prepay, redeem, purchase or defease such Debt shall be
          required to be made, in each case prior to the stated maturity
          thereof; or

          (g) the Parent or any Loan Party shall generally not pay its debts as
     such debts become due, or shall admit in writing its inability to pay its
     debts generally, or shall make a general assignment for the benefit of
     creditors; or any proceeding shall be instituted by or against the Parent,
     any Loan Party or any of its Subsidiaries seeking to adjudicate it as
     bankrupt or insolvent, or seeking liquidation, winding up, reorganization,
     concordato, arrangement, adjustment, protection, relief, or composition of
     it or its debts under any law relating to bankruptcy, insolvency,
     reorganization or concordato or relief of debtors, or seeking the entry of
     an order for relief or the appointment of a receiver, trustee, custodian or
     other similar official for it or for any substantial part of its property
     and, in the case of any such proceeding instituted against it (but not
     instituted by it) that is being diligently contested by it in good faith,
     either such proceeding shall remain undismissed, unvacated or unstayed for
     a period of 60 days, or any of the actions sought in such proceeding
     (including without limitation the entry of an order for relief against, or
     the appointment of a receiver, trustee, custodian or other similar official
     for, it or for any substantial part of its property) shall occur; or the
     Parent, any Loan Party or any of its Subsidiaries shall take any corporate
     action to authorize any of the actions set forth above in this subsection
     (g); or

          (h) any judgment or order for the payment of money in excess of
     $5,000,000 shall be rendered against the Parent, the Borrower or any of its
     Subsidiaries and either (i) enforcement proceedings shall have been
     commenced by any creditor upon such judgment or order or (ii) there shall

     such judgment or order, by reason of a pending appeal or otherwise, shall
     not be in effect; or

          (i) any non-monetary judgment or order shall be rendered against the

     of enforcement of such judgment or order, by reason of a pending appeal or
     otherwise, shall not be in effect; or

          (j) the Borrower or any of its ERISA Affiliates shall incur, or in the
     reasonable opinion of the Required Lenders shall be reasonably likely to
     incur liability in excess of $1,000,000 in the aggregate as a result of one

          (n) any Core Territory shall declare a moratorium on the payment of
     external debt or impose any restrictions on access to foreign exchange or
     transfer of funds, in any case, and such declaration or imposition is
     reasonably likely to have a Material Adverse Effect; or

          (o) there shall occur any condemnation, taking or expropriation of any
     assets of the Borrower or any of its Subsidiaries that is reasonably likely
     to result in a Material Adverse Effect; or

          (p) in the view of the Lenders, a Material Adverse Change shall occur;
     or

          (q) any default on the part of the Borrower or any of its Subsidiaries
     to comply with its obligations under Section 11.2 of the Supply Agreement

such interest and all such amounts shall become and be forthwith due and
payable, without presentment, demand, protest or further notice of any kind, all
of which are hereby expressly waived by the Borrower, and (iii) shall at the
request, or may with the consent, of the Required Lenders, foreclose on any and
all of the Collateral in accordance with the terms of the relevant Security
Agreements; provided that upon the occurrence of an Event of Default under

                                   ARTICLE VII

                            THE ADMINISTRATIVE AGENT

     SECTION 7.01. Authorization and Action. Each Lender hereby appoints and
authorizes the Administrative Agent to take such action as agent on its behalf
and to exercise such powers and discretion under this Agreement as are delegated
to the Administrative Agent by the terms hereof, together with such powers and
discretion as are reasonably incidental thereto. As to any matters not expressly
provided for by this Agreement (including without limitation enforcement or
collection of the Notes), the Administrative Agent shall not be required to
exercise any discretion or take any action, but shall be required to act or to
refrain from acting (and shall be fully protected in so acting or refraining
from acting) upon the instructions of the Required Lenders, and such
instructions shall be binding upon all Lenders and all holders of Notes;
provided that the Administrative Agent shall not be required to take any action
that exposes the Administrative Agent to personal liability or that is contrary
to this Agreement or applicable law. The Administrative Agent agrees to give to
each Lender prompt notice of each notice given to it by the Borrower pursuant to
the terms of this Agreement.

     SECTION 7.02. Agent's Reliance, Etc. Neither the Administrative Agent nor
any of its respective directors, officers, agents or employees shall be liable
for any action taken or omitted to be taken by it or them under or in connection
with this Agreement, except for its or their own gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, the
Administrative Agent: (i) may treat the payee of any Note as the holder thereof
until the Administrative Agent receives and accepts an Assignment and Acceptance
entered into by the Lender that is the payee of such Note, as assignor, and an
Eligible Assignee, as assignee, as provided in Section 8.07; (ii) may consult
with legal counsel (including counsel for the Borrower), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken in good faith by it in accordance with the
advice of such counsel, accountants or experts; (iii) makes no warranty or
representation to any Lender and shall not be responsible to any Lender for any
statements, warranties or representations (whether written or oral) made in or
in connection with this Agreement; (iv) shall not have any duty to ascertain or
to inquire as to the performance or observance of any of the terms, covenants or
conditions of this Agreement on the part of the Borrower or to inspect the
property (including the books and records) of the Borrower; (v) shall not be
responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of, or the perfection or
priority of any lien or security interest created or purported to be created
under or in connection with, this Agreement or any other instrument or document
furnished pursuant hereto; and (vi) shall incur no liability under or in respect
of this Agreement by acting upon any notice, consent, certificate or other
instrument or writing (which may be by telecopier, telegram or telex) believed
by it to be genuine and signed or sent by the proper party or parties.

     SECTION 7.03. Agent and Affiliates. With respect to its Commitment, the
Advances made by it and the Note issued to it, if any, the Person serving as the
Administrative Agent hereunder shall have the same rights and powers under this
Agreement as any other Lender and may exercise the same as though it were not
the Administrative Agent; and the term
<PAGE>

                                       85



"Lender" or "Lenders" shall, unless otherwise expressly indicated, include the
Administrative Agent in its individual capacity. Any Person serving as
Administrative Agent and its Affiliates may accept deposits from, lend money to,
act as trustee under indentures of, accept investment banking engagements from
and generally engage in any kind of business with, the Borrower, any of its
Subsidiaries and any Person who may do business with or own securities of the
Borrower or any such Subsidiary, all as if the Person serving as Administrative
Agent were not the Administrative Agent and without any duty to account therefor
to the Lenders.

     SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent or any other
Lender and based on the financial statements referred to in Section 4.01 and
such other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement.

     SECTION 7.05. Indemnification. The Lenders agree to indemnify the
Administrative Agent (to the extent not reimbursed by the Borrower), ratably
according to the respective principal amounts of the Notes then held by each of
the Lenders (or if no Notes are at the time outstanding or if the Notes are held
by Persons that are not Lenders, ratably according to the respective amounts of
their Commitments), from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever that may be imposed on, incurred
by, or asserted against the Administrative Agent, in any way relating to or
arising out of this Agreement or any action taken or omitted by the
Administrative Agent under this Agreement (collectively, the "Indemnified
Costs"); provided that no Lender shall be liable for any portion of the
Indemnified Costs resulting from the gross negligence or willful misconduct of
the Administrative Agent. Without limitation of the foregoing, each Lender
agrees to reimburse the Administrative Agent promptly upon demand for its
ratable share of any out-of-pocket expenses (including counsel fees) incurred by
it in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, to the extent that such agent is not
reimbursed for such expenses by the Borrower. In the case of any investigation,
litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05
applies whether any such investigation, litigation or proceeding is brought by
the Administrative Agent, any Lender or a third party.

     SECTION 7.06. Successor Agent. The Administrative Agent may resign at any
time by giving written notice thereof to the Lenders and the Borrower and may be
removed at any time with or without cause by the Required Lenders. Upon any such

successor Administrative Agent. If no

successor Administrative Agent shall have been so appointed by the Required
Lenders, and shall have accepted such appointment, within 30 days after such
retiring agent's giving of notice of resignation or the Required Lenders'
removal of such retiring agent, then such retiring agent may, on behalf of the
Lenders, appoint a successor Administrative Agent, which shall be a commercial
bank organized or licensed to do business under the laws of the United States of
America or of any State thereof and having a combined capital and surplus of at
least $1,000,000,000. Upon the acceptance of any appointment as Administrative

Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, discretion, privileges and duties of the retiring Administrative
Agent and the retiring Administrative Agent shall be discharged from its duties
and obligations under this Agreement. After any such retiring agent's
resignation or removal hereunder as Administrative Agent, the provisions of this

     SECTION 8.03. No Waiver; Remedies. No failure on the part of any Lender,
the Administrative Agent or the Collateral Agent to exercise, and no delay in
exercising, any right hereunder or under any Note shall operate as a waiver
thereof; nor shall any single or partial exercise of any such right preclude any

remedies herein provided are cumulative and not exclusive of any remedies
provided by law.

     SECTION 8.04. Costs and Expenses; Indemnification. (a) The Borrower will
pay on demand

          (i) all costs and expenses of the Administrative Agent and the Lenders
     in connection with the preparation, execution, delivery, administration,
     modification and amendment of the Loan Documents (including, without
     limitation, (A) all due diligence, collateral review, syndication,

     or interests, under the Loan Documents, with respect to negotiations with
     any Loan Party or with other creditors of any Loan Party or any of its
     Subsidiaries arising out of any Default or any events or circumstances that
     may give rise to a Default and with
<PAGE>

                                       89



     respect to presenting claims in or otherwise participating in or monitoring
     any bankruptcy, insolvency or other similar proceeding involving creditors'
     rights generally and any proceeding ancillary thereto), and

          (ii) all costs and expenses of the Administrative Agent and the Lender
     Parties in connection with the enforcement of the Loan Documents, whether
     in any action, suit or litigation, any bankruptcy, insolvency or other
     similar proceeding affecting creditors' rights generally (including,
     without limitation, the reasonable fees and expenses of a single counsel
     for the Administrative Agent and each Lender Party in each relevant
     jurisdiction with respect thereto).

     (b) The Borrower will indemnify and hold harmless the Administrative Agent
and each Lender and each of their Affiliates and their officers, directors,
employees, agents and advisors (each, an "Indemnified Party") from and against
any and all claims, damages, losses, liabilities and expenses (including without
limitation reasonable fees and expenses of counsel) that may be incurred by or
asserted or awarded against any Indemnified Party, in each case arising in any
way out of or in connection with or by reason of (i) the Notes, this Agreement,
any of the transactions contemplated herein or the actual or proposed use of the
proceeds of the Advances, except to the extent such claim, damage, loss,
liability or expense resulted from such Indemnified Party's gross negligence or
willful misconduct. In the case of an investigation, litigation or other
proceeding to which the indemnity in this Section 8.04(b) applies, such
indemnity shall be effective whether or not such investigation, litigation or
proceeding is brought by the Borrower, its directors, shareholders or creditors
or an Indemnified Party or any other Person or any Indemnified Party is
otherwise a party thereto and whether or not the transactions contemplated
hereby are consummated. The Borrower also agrees not to assert any claim against
the Agent, any Lender, any of their Affiliates, or any of their respective
directors, officers, employees, attorneys and agents, on any theory of
liability, for special, indirect, consequential or punitive damages arising out
of or otherwise relating to the Notes, this Agreement, any of the transactions
contemplated herein or the actual or proposed use of the proceeds of the
Advances.

     (c) If any payment of principal of any Advance is made by the Borrower to
or for the account of a Lender other than on the last day of the Interest Period
for such Advance, as a result of a payment pursuant to Section 2.09(c) and (d),
acceleration of the maturity of the Notes pursuant to Section 6.01 or for any
other reason, the Borrower shall, upon written demand by such Lender (with a
copy of such demand to the Administrative Agent), pay to the Administrative
Agent for the account of such Lender any amounts reasonably required to
compensate such Lender for any additional losses, costs or expenses that it may
reasonably incur as a result of such payment, including without limitation any
loss, cost or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by any Lender to fund or maintain such Advance.
The loss to any Lender attributable to any such event shall be deemed to be an
amount determined by such Lender to be equal to the excess, if any, of (i) the
amount of interest that such Lender would pay for a deposit equal to the
principal amount of the applicable Eurodollar Rate Advance so prepaid or
accelerated, as applicable, for the period from the date of such payment or
acceleration to the last day of the then current Interest Period for
<PAGE>

                                       90



such Eurodollar Rate Advance if the interest rate payable on such deposit were
equal to the Eurodollar Rate for such Interest Period, over (ii) the amount of
interest that such Lender would earn on such principal amount for such period if
such Lender were to invest such principal amount for such period at the interest
rate that would be bid by such Lender (or an Affiliate of such Lender) for
dollar deposits from other banks in the eurodollar market at the commencement of
such period. A certificate as to the amount of such loss, cost or expense,
submitted to the Borrower by such Lender, shall be conclusive and binding for
all purposes, absent manifest error.

     (d) If any Loan Party fails to pay when due any costs, expenses or other
amounts payable by it under any Loan Document, including, without limitation,
fees and expenses of counsel and indemnities, such amount may be paid on behalf
of such Loan Party by the Agents or any Lender Party, in its sole discretion.

     (e) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
Sections 2.09, 2.11 and 8.04 shall survive the payment in full of principal,
interest and all other amounts payable hereunder and under the Notes.

     SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during the
continuance of any Event of Default and (ii) the making of the request or the
granting of the consent specified by Section 6.01 to authorize the
Administrative Agent to declare the Notes due and payable pursuant to the
provisions of Section 6.01, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any
time owing by such Lender or such Affiliate to or for the credit or the account
of the Borrower against any and all of the obligations of the Borrower now or
hereafter existing under this Agreement and the Note held by such Lender,
whether or not such Lender shall have made any demand under this Agreement or
such Note and although such obligations may be unmatured. Each Lender agrees
promptly to notify the Borrower in writing after any such set-off and
application; provided that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of each Lender and its
Affiliates under this Section 8.05 are in addition to other rights and remedies
(including without limitation other rights of set-off) that such Lender and its
Affiliates may have.

     SECTION 8.06. Binding Effect. This Agreement shall become effective (other
than Section 2.01(a), which shall only become effective upon satisfaction of the
conditions precedent set forth in Sections 3.01), when (i) this Agreement shall
have been executed by the Borrower, the Administrative Agent and the Initial
Lender, and thereafter this Agreement shall be binding upon and inure to the
benefit of the Borrower, the Administrative Agent and each Lender and their
respective successors and assigns, except that the Borrower shall not have the
right to assign its rights hereunder or any interest herein without the prior
written consent of the Lenders.
<PAGE>

                                       91



     SECTION 8.07. Assignments and Participations. (a) Each Lender may assign to
an Eligible Assignee all or a portion of its rights and obligations under this
Agreement (including without limitation all or a portion of its Commitment, the
Advances owing to it and the Note or Notes held by it and either outstanding
Advances or Commitments); provided that (i) except in the case of an assignment
to a Person that, immediately prior to such assignment, was a Lender or an
assignment of all of a Lender's rights and obligations under this Agreement, the
amount of the Advances and unfunded Commitment of the assigning Lender being
assigned pursuant to each such assignment (determined as of the date of the
Assignment and Acceptance with respect to such assignment) shall in no event be
less than $5,000,000 (except that this clause shall not prohibit the assignment
of a Fronting Commitment as contemplated by Section 2.02 in an amount equal to
the Advance that the Initial Lender would have made but for such assignment) and
(ii) the parties to each such assignment shall execute and deliver to the
Administrative Agent, for its acceptance and recording in the Register, an
Assignment and Acceptance, together with any Note subject to such assignment
and, except in the case of an assignment by the Initial Lender, a processing and
recordation fee of $3,500. Notwithstanding the foregoing, nothing in this
Section shall be construed to prohibit the assignment of a proportionate part of
all of the assigning Lender's rights and obligations in respect of (A) Advances
separately from (or without assigning) Commitments, (B) Commitments separately
from (or without assigning) Advances, (C) Tranche A Commitments or Tranche A
Advances separately from (or without assigning) Tranche B Commitments or Tranche
B Advances or (D) Tranche B Commitments or Tranche B Advances separately from
(or without assigning) Tranche A Commitments or Tranche A Advances. Upon such
execution, delivery, acceptance and recording, from and after the effective date
specified in each Assignment and Acceptance, (x) the assignee thereunder shall
be a party hereto and, to the extent that rights and obligations hereunder have
been assigned to it pursuant to such Assignment and Acceptance, have the rights
and obligations of a Lender hereunder and (y) the Lender assignor thereunder
shall, to the extent that rights and obligations hereunder have been assigned by
it pursuant to such Assignment and Acceptance, relinquish its rights and be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such Lender shall upon
such assignment cease to be a party hereto).

     (b) By executing and delivering an Assignment and Acceptance, the Lender
assignor thereunder and the assignee thereunder confirm to and agree with each
other and the other parties hereto as follows: (i) other than as provided in
such Assignment and Acceptance, such assigning Lender makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of, or the perfection or priority of any lien or security interest created
or purported to be created under or in connection with, this Agreement or any
other instrument or document furnished pursuant hereto; (ii) such assigning
Lender makes no representation or warranty and assumes no responsibility with
respect to the financial condition of the Borrower or the performance or
observance by the Borrower of any of its obligations under this Agreement or any
other instrument or document furnished pursuant hereto; (iii) such assignee
confirms that it has received a copy of this Agreement and the Intercreditor
Agreement, together with copies of the
<PAGE>

                                       92



financial statements referred to in Section 4.01 and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (iv) such assignee will,
independently and without reliance upon the Administrative Agent, such assigning
Lender or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement; (v) such assignee confirms
that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the
Administrative Agent and the Collateral Agent to take such action as agent on
its behalf and to exercise such powers and discretion under this Agreement as
are delegated to the Administrative Agent and the Collateral Agent by the terms
hereof, together with such powers and discretion as are reasonably incidental
thereto; and (vii) such assignee agrees that it will perform in accordance with
their terms all of the obligations that by the terms of this Agreement and the
Intercreditor Agreement are required to be performed by it as a Lender.

     (c) The Administrative Agent shall maintain at its address referred to in
Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted
by it and a register for the recordation of the names and addresses of the
Lenders and the Commitment of, and principal amount of the Advances owing to,
each Lender from time to time (the "Register"). The entries in the Register
shall be conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Administrative Agent, the Collateral Agent and the Lenders may
treat each Person whose name is recorded in the Register as a Lender hereunder
for all purposes of this Agreement. The Register shall be available for
inspection by the Borrower or any Lender at any reasonable time and from time to
time upon reasonable prior notice.

     (d) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee representing that it is an Eligible Assignee,
together with any Note or Notes subject to such assignment, the Administrative
Agent shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit C, (i) accept such Assignment and Acceptance,
(ii) record the information contained therein in the Register and (iii) give
prompt written notice thereof to the Borrower. Within five Business Days after
its receipt of such notice and at the request of such assignee Lender, the
Borrower, at its own expense, shall execute and deliver to the Administrative
Agent in exchange for any surrendered Note a new Note to the order of such
Assignee in an amount equal to the Commitment assumed by it pursuant to such
Assignment and Acceptance and, if the assigning Lender has retained a Commitment
hereunder, a new Note to the order of the assigning Lender in an amount equal to
the Commitment retained by it hereunder. Such new Note or Notes shall be in an
aggregate principal amount equal to the aggregate principal amount of such
surrendered Note or Notes, shall be dated the effective date of such Assignment
and Acceptance and shall otherwise be in substantially the form of Exhibit A.

     (e) Each Lender may sell participations to one or more banks or other
entities (other than the Borrower or any of its Affiliates) in or to all or a
portion of its rights and obligations under this Agreement (including without
limitation all or a portion of its Commitment, the Advances owing to it and the
Note or Notes held by it); provided that (i) such
<PAGE>

                                       93



Lender's obligations under this Agreement (including without limitation its
Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Lender
shall remain solely responsible to the other parties hereto for the performance
of such obligations, (iii) such Lender shall remain the holder of any such Note
for all purposes of this Agreement, (iv) the Borrower, the Administrative Agent,
the Collateral Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and (v) no participant under any such
participation shall have any right to approve any amendment or waiver of any
provision of this Agreement or any Note, or any consent to any departure by the
Borrower therefrom, except to the extent that such amendment, waiver or consent
would reduce the principal of, or interest on, the Notes or any fees or other
amounts payable hereunder, in each case to the extent subject to such
participation, postpone any date fixed for any payment of principal of, or
interest on, the Notes or any fees or other amounts payable hereunder, in each
case to the extent subject to such participation, or to the extent that any such
amendment or consent provides for a release of the Borrower's obligations under
the Security Agreements or any Subsidiary's obligations under any Guaranty.

     (f) Any Lender may, in connection with any assignment or participation or
proposed assignment or participation pursuant to this Section 8.07, disclose to
the assignee or participant or proposed assignee or participant, any information
relating to the Borrower furnished to such Lender by or on behalf of the
Borrower; provided that, prior to any such disclosure, the assignee or
participant or proposed assignee or participant shall agree in writing to
preserve the confidentiality of any Confidential Information relating to the
Borrower received by it from such Lender.

     (g) Notwithstanding any other provision set forth in this Agreement, any
Lender may at any time create a security interest in all or any portion of its
rights under this Agreement (including without limitation the Advances owing to
it and the Note held by it) in favor of any Federal Reserve Bank in accordance
with Regulation A of the Board of Governors of the Federal Reserve System.

     SECTION 8.08. Confidentiality. Neither the Administrative Agent nor any
Lender shall disclose any Confidential Information to any other Person without
the consent of the Borrower, other than (a) to the Administrative Agent's, the
Collateral Agent or such Lender's Affiliates and their officers, directors,
employees, agents and advisors and, as contemplated by Section 8.07(f), to
actual or prospective assignees and participants, and then only on a
confidential basis, (b) to any party to the Intercreditor Agreement, (c) as
required by any law, rule or regulation or judicial process and (d) as requested
or required by any state, federal or foreign authority or examiner regulating
banks or banking.

     SECTION 8.09. Governing Law. This Agreement and the Notes shall be governed
by, and construed in accordance with, the laws of the State of New York.

     SECTION 8.10. Execution in Counterparts. This Agreement may be executed in

counterparts, each of
<PAGE>

                                       94



which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement. Delivery of an executed
counterpart of a signature page to this Agreement by telecopier shall be
effective as delivery of a manually executed counterpart of this Agreement.

     SECTION 8.11. Jurisdiction, Judgment Currency, Etc. (a) Each of the parties
hereto hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
federal court of the United States of America sitting in New York City in the
Borough of Manhattan, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to this Agreement or the Notes, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in any such New York State
court or, to the extent permitted by law, in such federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement shall
affect any right that any party may otherwise have to bring any action or
proceeding relating to this Agreement or the Notes in the courts of any
jurisdiction.

     (b) Each of the parties hereto irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection that it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement or the Notes in any New
York State or federal court. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

     (c) (i) If, for the purpose of obtaining judgment in any court, it is
necessary to convert a sum due hereunder to any party hereunder in one currency
into another currency, the parties hereto agree, to the fullest extent permitted
by law, that the rate of exchange used shall be that at which in accordance with
its normal banking procedures such party could purchase the first currency with
such other currency on the day which is at least two Business Days prior to the
day on which final judgment is rendered.

     (ii) To the fullest extent permitted by law, the obligation of any party in
respect of any sum payable hereunder by it to any other party hereunder shall,
notwithstanding any judgment in a currency (the "Judgment Currency") other than
Dollars (the "Agreement Currency"), be discharged only to the extent that on the
Business Day following receipt by such other party of any sum adjudged to be so
due in the Judgment Currency such other party may in accordance with normal
banking procedures purchase the Agreement Currency with the Judgment Currency;
if the amount of the Agreement Currency which could have been so purchased is
less than the sum originally due to such other party in the Agreement Currency,
such first party agrees, as a separate obligation and notwithstanding any such
judgment, to indemnify such other party against such loss, and, if the amount of
the Agreement Currency which could have been so purchased exceeds the sum
originally due to such other party, such
<PAGE>

                                       95



other party agrees to remit to such first party such excess; provided that
neither any Lender nor the Administrative Agent shall have any obligation to
remit any such excess as long as the Borrower shall have failed to pay any
Lender or the Administrative Agent, as the case may be, any obligations due and
payable under this Agreement, in which case such excess may be applied to such
obligations of the Borrower hereunder in accordance with the terms of this
Agreement.

     SECTION 8.12. Waiver of Jury Trial. Each of the Borrower, the
Administrative Agent and the Lenders hereby irrevocably waive, to the extent
permitted by law, all right to trial by jury in any action, proceeding or
counterclaim (whether based on contract, tort or otherwise) arising out of or
relating to this Agreement or the Notes or the actions of any Agent or any
Lender in the negotiation, administration, performance or enforcement thereof.

     SECTION 8.13. Intercreditor Arrangements. Each of the Lenders and the
Borrower acknowledge that the Lenders hereunder, together with any Other Secured
Creditors, shall be considered to be joint creditors (credores solidarios) with
respect to the Obligations under the Loan Documents and the obligations owed to
such Other Secured Creditors; provided that if requested by the Borrower, any
Other Secured Creditors or potential Other Secured Creditors, the Lenders and
the Agents agree to negotiate in good faith with a view to agreeing to a
substitute structure governing the equal sharing of Collateral under Brazilian
law and to documentation reflecting such structure.

     SECTION 8.14. Intercreditor Agreement; Amendments to Ericsson Credit
Agreement. Except with the consent of the Borrower, the Lenders shall not amend
or modify Section 4.1(a) of the Intercreditor Agreement in a manner that would
add to the limitations set forth therein on the ability of the lenders party to
any Permitted Loan Agreement (as defined in the Intercreditor Agreement) to
agree to amendments to or modifications of such Permitted Loan Agreement. The
Borrower shall not enter into any amendment to or modification of the Ericsson
Credit Agreement unless it shall at the same time have offered to enter into an

                      AMENDED AND RESTATED CREDIT AGREEMENT


     AMENDED AND RESTATED CREDIT AGREEMENT dated as of November 24, 1999 among
DIVEO, INC., a Delaware corporation (the "Borrower"), ERICSSON CREDIT AB (the
"Initial Lender") and ERICSSON CREDIT AB as administrative agent (the
"Administrative Agent") for the Lenders (as hereinafter defined).

                                    RECITALS

     The Borrower has been formed in order to plan, construct, operate and
maintain digital wireless local loop voice and data networks (each, a "Network")
in Mexico, Central America and South America (the "Territory") (the planning,
construction, operation and maintenance of the Networks being the "Project").

     The Borrower entered into the Relationship Agreement dated as of June 25,
1999 with LM Ericsson Telefonaktiebolaget (together with any of its Subsidiaries
providing services pursuant to the Relationship Agreement or providing financing
hereunder, "Vendor") (the "Relationship Agreement", and together with any
Specific Agreements (as defined therein), in each case as amended, modified or
supplemented from time to time, the "Supply Agreement") pursuant to which
Subsidiaries of the Borrower will purchase from Subsidiaries of the Vendor, and
Subsidiaries of the Vendor will sell to Subsidiaries of the Borrower, certain
telecommunications equipment, software, engineering and other services in
connection with the Project. In connection with the execution of the Supply
Agreement, the Borrower and the Vendor entered into the Credit Agreement dated
as of June 25, 1999 (the "Original Credit Agreement"), pursuant to which the
Vendor as Initial Lender would provide financing for purchases made by
Subsidiaries of the Borrower pursuant to the Supply Agreement.

     In connection with an amendment to the Supply Agreement, the Borrower and
the Lenders desire to amend and restate the Original Credit Agreement in its
entirety in accordance with the terms hereof (the "Agreement" or "this
Agreement"). Pursuant to this Agreement, the Borrower has requested that (i) the
Lenders extend credit to it from time to time in order to finance certain costs
of the Project, including, among other things, purchases under the Supply
Agreement and (ii) the terms and conditions of the Original Credit Agreement
with respect to credit extended by the Lenders thereunder prior to the date
hereof be superseded by the terms and conditions of this Agreement with respect
to such credit. The Lenders have agreed to extend credit to the Borrower from
time to time under the terms and conditions of this Agreement, and the Lenders
have agreed that the terms and conditions of this Agreement shall supersede the
terms and conditions of the Original Credit Agreement with respect to credit
extended thereunder prior to the date of effectiveness of this Agreement
pursuant to Section 3.03.

for the account of its Lending Office to the Administrative Agent at the
Administrative Agent's Account, in same day funds, such Lender's ratable portion
of such Borrowing. After the Administrative Agent's receipt of such funds and

Administrative Agent will make such funds available to the Borrower. The
Borrower irrevocably directs the Administrative Agent to make available to the
Borrower the portion of any Borrowing to be used to pay amounts owing to the
Vendor, as specified in the related Notice of Borrowing to account no.

the Lenders entitled thereto; provided that, if such account is not with the

Administrative Agent shall have initiated the transfer of funds comprising such
Borrowing to such account.

     (b) Each Notice of Borrowing shall be irrevocable and binding on the

expense incurred by such Lender as a result of any failure to fulfill on or

<PAGE>

                                       29



(without limitation) any loss, cost or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by such Lender
to fund the Advance to be made by such Lender as part of such Borrowing when
such Advance, as a result of such failure, is not made on such date. The loss to
any Lender attributable to any such failure shall be deemed to be an amount
determined by such Lender to be equal to the excess, if any, of (i) the amount
of interest that such Lender would pay for a deposit equal to the principal
amount of the applicable Eurodollar Rate Advance not borrowed for the duration
of the Interest Period that would have resulted from such borrowing if the
interest rate payable on such deposit were equal to the Eurodollar Rate for such
Interest period, over (ii) the amount of interest that such Lender would earn on
such principal amount for such period if such Lender were to invest such
principal amount for such period at the interest rate that would be bid by such
Lender (or an Affiliate of such Lender) for dollar deposits from other banks in
the eurodollar market at the commencement of such period. A certificate as to
the amount of such loss, cost or expense, submitted to the Borrower by such
Lender, shall be conclusive and binding for all purposes, absent manifest error.

     (c) Unless the Administrative Agent shall have received notice from a
Lender that has an applicable Commitment prior to the date of any Borrowing that
such Lender will not make available to the Administrative Agent such Lender's
ratable portion of such Borrowing, the Administrative Agent may assume that such
Lender has made such portion available to the Administrative Agent on the date
of such Borrowing in accordance with subsection (a) of this Section 2.02 and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower on such date a corresponding amount. If and to the extent that such
Lender shall not have so made such ratable portion available to the
Administrative Agent, such Lender and the Borrower severally agree to repay to
the Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is repaid to the Administrative
Agent, at (i) in the case of the Borrower, the interest rate applicable at the
time to Advances comprising such Borrowing and (ii) in the case of such Lender,
the Federal Funds Rate. If such Lender shall repay to the Administrative Agent
such corresponding amount, such amount so repaid shall constitute such Lender's
Advance as part of such Borrowing for purposes of this Agreement.

     (d) The failure of any Lender obligated to make an Advance to make such
Advance to be made by it as part of any Borrowing shall not relieve any other
Lender of its obligation, if any, hereunder to make its Advance on the date of
such Borrowing, but no Lender shall be responsible for the failure of any other
Lender to make any Advance to be made by such other Lender on the date of any
Borrowing.

the Lenders that have made Tranche A Advances the aggregate outstanding
principal amount of the Tranche A Advances in six installments payable on the
last day of every sixth calendar month after the second anniversary of the
Amendment Effective Date each in an amount equal to the product obtained by
multiplying (i) the unpaid principal amount of such Tranche A Advances
outstanding on the Tranche A Termination Date by (ii) 16-2/3%; provided that the
last such installment shall be in an amount necessary to repay in full the
aggregate then-unpaid principal amount of the Tranche A Advances. Each repayment
shall be applied to the unpaid principal amount of Tranche A Advances ratably
across all Borrowings. At the time of such repayment, the Borrower also will pay
accrued and unpaid interest owing on the principal amount of the Tranche A
Advances then being repaid.

     (b) Repayment of Tranche B Advances. The Borrower shall repay to the
Administrative Agent for the ratable account of the Lenders that have made
Tranche B Advances the aggregate outstanding principal amount of the Tranche B
Advances in seven installments payable on the last day of every sixth calendar
month after the eighteen month anniversary of the Tranche B Effective Date each
in an amount equal to the product obtained by multiplying (a) the unpaid
principal amount of such Tranche B Advances outstanding on the Tranche B
Termination Date by (b) 14.29%; provided that the last such installment shall be
in an amount necessary to repay in full the unpaid principal amount of the
Tranche B Advances. Each repayment shall be applied to the unpaid principal
amount of Tranche B Advances ratably across all Borrowings. At the time of such
repayment, the Borrower also will pay accrued and unpaid interest owing on the
principal amount of the Tranche B Advances then being repaid.

     SECTION 2.06. Interest. (a) Scheduled Interest. Except as otherwise
provided in Section 2.09, the Borrower shall pay interest on the unpaid
principal amount of each Advance owing to each Lender from the date of such
Advance until such principal amount shall be paid in full, at a rate per annum
equal at all times during each Interest Period for such Advance to the sum of
(x) the Eurodollar Rate for such Interest Period for such Advance plus (y)
5.75%, payable in arrears on the last day of such Interest Period and on the
date such Advance shall be paid in full.

     (b) Default Interest. Upon the occurrence and during the continuance of an
Event of Default under Section 6.01(a), the Borrower shall pay interest on (i)
the unpaid principal amount of each Advance owing to each Lender, payable in
arrears on the dates referred to in clause (a) above or Section 2.09(c) or (d)
and on demand, at a rate per annum equal at all
<PAGE>

                                       32



times to 2% per annum above the rate per annum required to be paid on such
Advance pursuant to clause (a) above or Section 2.09(c) or (d) and (ii) to the
fullest extent permitted by law, the amount of any interest, fee or other amount
payable hereunder that is not paid when due, from the date such amount shall be
due until such amount shall be paid in full, payable in arrears on the date such
amount shall be paid in full and on demand, at a rate per annum equal at all
times to 2% per annum above the rate per annum required to be paid on Advances
pursuant to clause (a) above.

     SECTION 2.07. Interest Rate Determination. The Administrative Agent shall
give prompt notice to the Borrower and the Lenders of the applicable interest
rate determined by the Administrative Agent for purposes of Section 2.06(a) or
Section 2.09(c) or (d) prior to the commencement of each Interest Period;
provided that any failure by the Administrative Agent to give such notice shall
not affect such applicable interest rate or the Borrower's obligations
hereunder, or give rise to any liability on behalf of the Administrative Agent.

     SECTION 2.08. Prepayments. (a) Optional Prepayments. The Borrower may, upon
at least 10 Business Days' notice to the Administrative Agent stating the
proposed date and aggregate principal amount of the prepayment, and if such
notice is given the Borrower shall, prepay the outstanding principal amount of
the Advances; provided that (i) each partial prepayment shall be in an aggregate
principal amount of $3,000,000 or an integral multiple of $1,000,000 in excess
thereof and (ii) the Borrower shall be obligated to reimburse the Lenders in
respect thereof pursuant to Section 8.04(c).

     (b) Mandatory Prepayments. (i) Sales of Assets. The Borrower shall, on each
date on which the Borrower or any Subsidiary thereof receives any Net Cash
Proceeds from the sale, lease, transfer or other disposition (other than

the Borrower or any Subsidiary thereof, prepay an aggregate principal amount of
the Advances equal to the Lenders' Pro Rata Portion of such Net Cash Proceeds
(or, if less, the aggregate principal amount of all Advances); provided that the
Borrower shall not be required to make any prepayment pursuant to this
subsection from any such Net Cash Proceeds it intends to apply to the purchase
of any Capital Assets so long as:

          (A) the Borrower shall have notified the Administrative Agent of such
     intent by the date on which such prepayment otherwise would be required;

     evidence satisfactory to the Administrative Agent that such Capital Assets
     were purchased within such 180-day period.
<PAGE>

                                       33



If the Borrower shall not have made a prepayment pursuant to this subsection
because of the proviso hereto and shall not have fulfilled the conditions set
forth in such proviso within the period specified therein, it shall make the
prepayment required by this subsection at the end of such period and the proviso
hereto shall no longer be applicable to such prepayment.

     (ii) Insurance Recoveries. The Borrower shall, on each date on which it or
any Subsidiary thereof receives any Net Cash Proceeds from any property and
casualty insurance recovery, prepay an aggregate principal amount of the

     intent by the date on which such prepayment otherwise would be required;

          (B) such Net Cash Proceeds shall have been so applied within 60 days
     after the date the Borrower or a Subsidiary thereof received such Net Cash
     Proceeds; and

          (C) the Borrower or any Subsidiary thereof shall have provided the
     Administrative Agent with evidence satisfactory to the Administrative Agent
     that such Net Cash Proceeds were so applied within such 60-day period.

If the Borrower shall not have made a prepayment pursuant to this subsection
because of the proviso hereto and shall not have fulfilled the conditions set
forth in such proviso within the period specified therein, it shall make the
prepayment required by this subsection at the end of such period and the proviso
hereto shall no longer be applicable to such prepayment.

     (iii) Condemnation Recoveries. The Borrower shall, on each date on which it
or any Subsidiary thereof receives any Net Cash Proceeds from any condemnation
proceeds or similar awards received by the Borrower or any Subsidiary thereof in
connection with any governmental taking of assets of the Borrower or any
Subsidiary thereof, prepay an aggregate principal amount of the Advances equal

aggregate principal amount of all Advances); provided that the Borrower shall
not be required to make any prepayment pursuant to this subsection from any such
Net Cash Proceeds it intends to apply to the replacement of the condemned or

<PAGE>

                                       34



          (B) such Net Cash Proceeds shall have been so applied within 60 days
     after the date the Borrower or a Subsidiary thereof received such Net Cash
     Proceeds; and

          (C) the Borrower or any Subsidiary thereof shall have provided the
     Administrative Agent with evidence satisfactory to the Administrative Agent
     that such Net Cash Proceeds were so applied within such 60-day period.

If the Borrower shall not have made a prepayment pursuant to this subsection
because of the proviso hereto and shall not have fulfilled the conditions set
forth in such proviso within the period specified therein, it shall make the

under Section 4(2) of the Securities Act or (C) in accordance with the
registration and delivery requirements of Section 5 of the Securities Act,
prepay an aggregate principal amount of the Advances comprising part of the same
Borrowings equal to 50% of the Lenders' Pro Rata Portion of such Net Cash

     (v) Excess Cash Flow. The Borrower shall, within five Business Days of each
date upon which the Borrower is required to furnish to the Lenders its annual
financial statements pursuant to Section 5.03(d), deposit into an escrow account
(the terms of which shall be reasonably satisfactory to the Administrative
Agent) an amount equal to 50% of the Borrower's Excess Cash Flow for the
Borrower's fiscal year reflected in such report (for such fiscal year, the
"Excess Cash Flow Amount"). Upon the last day of the Interest Period during
which such deposit was made, the Borrower shall prepay an aggregate principal
amount of the Advances equal to the Lenders' Pro Rata Portion of such Excess
Cash Flow Amount (or, if the outstanding principal amount of the Advances is
less than the Lenders' Pro Rata Portion of such Excess Cash Flow Amount on such
day, the aggregate principal amount of all Advances). Any amounts remaining in
such escrow amount after such prepayment shall be released to the Borrower
immediately following such prepayment.

     (vi) Notice. The Borrower shall give the Administrative Agent at least five
Business Days' prior written notice of (A) each prepayment required by this
Section 2.08(b) and (B) the application of any Net Cash Proceeds pursuant to any

                                       35



     (c) Mechanics of Prepayments. All prepayments under this Section 2.08 shall
be made together with accrued interest to the date of such prepayment on the
principal amount prepaid and together with any amounts owing to the Lenders
pursuant to Section 8.04(c) in respect of such prepayment. Any prepayment of
Advances pursuant to this Section 2.08 shall be applied to the installments
thereof in inverse order of maturity, ratably across all Advances being so
prepaid. All prepayments under this Section 2.08 shall be made ratably with
prepayments to lenders under the other Permitted Loan Agreements (as defined in
the Intercreditor Agreement), in proportion with the outstanding principal
amounts owing by the Borrower under the Permitted Loan Agreements.

     SECTION 2.09. Increased Costs, Etc. (a) If, due to either (i) the
introduction of or any change (other than any change by way of imposition or
increase of reserve requirements included in the Eurodollar Rate Reserve
Percentage) in or in the interpretation of any law or regulation or (ii) the
compliance with any guideline or request from any central bank or other
governmental authority (whether or not having the force of law), there shall be
any increase in the cost to any Lender of agreeing to make or of making, funding
or maintaining Advances (excluding for purposes of this Section 2.09 any such
increased costs resulting from (A) Taxes or Other Taxes (as to which Section
2.11 shall govern) or (B) changes in the basis of taxation of overall net income
or overall gross income by the jurisdiction or state under the laws of which
such Lender is organized or has its Lending Office or any political subdivision
thereof), then the Borrower shall from time to time, upon demand by such Lender
(with a copy of such demand to the Administrative Agent), pay to the
Administrative Agent for the account of such Lender additional amounts
sufficient to compensate such Lender for such increased cost; provided that a
Lender claiming additional amounts under this Section 2.09(a) agrees to use
reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions) to designate a different Lending Office if the making of such a
designation would avoid the need for, or reduce the amount of, such increased
cost that may thereafter accrue and would not, in the reasonable judgment of
such Lender be otherwise disadvantageous to such Lender. If any Lender becomes
entitled to claim any additional amounts pursuant to this Section 2.09(a), it
will promptly notify the Borrower (with a copy of such notice to the
Administrative Agent) of the event by reason of which it has become so entitled
and provide a detailed calculation of the amount to be paid; provided that no
Lender shall be required to disclose in connection with such calculation any
information that it deems to be proprietary or confidential, including, without
limitation, any allocation of internal costs. A certificate as to the amount of
such increased cost, submitted to the Borrower by such Lender, shall be
conclusive and binding for all purposes, absent manifest error.

     (b) If any Lender determines that compliance with any law or regulation or
any guideline or request from any central bank or other governmental authority
(whether or not having the force of law) affects or would affect the amount of
capital required or expected to be maintained by such Lender or any corporation
controlling such Lender and that the amount of such capital is increased by or
based upon the existence of such Lender's commitment to lend
<PAGE>

                                       36



hereunder then, upon demand by such Lender (with a copy of such demand to the
Administrative Agent), the Borrower shall pay to the Administrative Agent for
the account of such Lender, from time to time as specified by such Lender,
additional amounts sufficient to compensate such Lender in the light of such
circumstances, to the extent that such Lender reasonably determines such
increase in capital to be allocable to the existence of such Lender's commitment
to lend hereunder; provided that, before making any such demand, such Lender
will use reasonable efforts (consistent with its internal policy and legal and
regulatory restrictions) to designate a different Lending Office if the making
of such a designation would allow such Lender or its Lending Office to continue
to perform its obligations to make Advances or to continue to fund or maintain
Advances and would not, in the judgment of such Lender, be otherwise
disadvantageous to such Lender. If any Lender becomes entitled to claim any
additional amounts pursuant to this Section 2.09(b), it will promptly notify the
Borrower (with a copy of such notice to the Administrative Agent) of the event
by reason of which it has become so entitled and provide a detailed calculation
of the amount to be paid; provided that no Lender shall be required to disclose
in connection with such calculation any information that it deems to be
proprietary or confidential, including, without limitation, any allocation of
internal costs. A certificate as to such amounts submitted to the Borrower by
such Lender shall be conclusive and binding for all purposes, absent manifest
error.

     (c) If, with respect to any Advances, a majority in interest of the Lenders
participating in such Advances notify the Administrative Agent that the
Eurodollar Rate for any Interest Period for such Advances will not adequately
reflect the cost to such Lenders of making, funding or maintaining their
Advances for such Interest Period, the Administrative Agent shall forthwith so
notify the Borrower, whereupon (i) each such Advance will automatically, on the
last day of the then existing Interest Period therefor, cease to bear interest
pursuant to Section 2.06(a) and from such date bear interest at a rate per annum
equal at all times to the sum of (A) the Base Rate in effect from time to time
plus (B) 6.25%, payable in arrears semi-annually on the last day of December and
June until the Administrative Agent shall notify the Borrower that such Lenders
have determined that the circumstances causing such suspension no longer exist
and (ii) the Borrower shall pay interest on the unpaid principal amount of each
Advance made after the giving of such notice by the Required Lenders from the
date of such Advance until the earlier of (A) the payment in full of such
Advance and (B) the date upon which the Administrative Agent has notified the
Borrower that such Lenders have determined that the circumstances causing such
suspension no longer exist, at a rate per annum equal to the actual cost
incurred by the Lenders in making such Advance plus 6.25%, payable in arrears
semi-annually on the last day of December and June. A certificate as to the rate
referred to in clause (ii) above submitted to the Borrower by such Lenders shall
be conclusive and binding for all purposes, absent manifest error.

     (d) Notwithstanding any other provision of this Agreement, if the
introduction of or any change in or in the interpretation of any law or
regulation shall make it unlawful, or any central bank or other governmental
authority shall assert that it is unlawful, for any Lender or its Lending Office
to perform its obligations hereunder to make Advances or to continue to fund or
<PAGE>

                                       37



maintain Advances hereunder, then, on notice thereof and demand therefor by the
Required Lenders to the Borrower through the Administrative Agent, (i) each
Advance will automatically, on such demand, cease to bear interest pursuant to
Section 2.06(a) and from such demand bear interest at a rate per annum equal at
all times to the sum of (A) the Base Rate in effect from time to time plus (B)
6.25%, payable in arrears semi-annually on the last day of each December and
June until the Administrative Agent shall notify the Borrower that such Lender
has determined that the circumstances causing such suspension no longer exist,
and (ii) the Borrower shall pay interest on the unpaid principal amount of each
Advance made after the giving of such notice by the Required Lenders from the
date of such Advance until the earlier of (A) the payment in full of such
Advance and (B) the date upon which the Administrative Agent has notified the
Borrower that such Lenders have determined that the circumstances causing such
suspension no longer exist, at a rate per annum equal to the actual cost
incurred by the Lenders in making such Advance plus 6.25%, payable in arrears
semi-annually on the last day of December and June; provided that, before making
any such demand, such Lender will use reasonable efforts (consistent with its
internal policy and legal and regulatory restrictions) to designate a different
Lending Office if the making of such a designation would allow such Lender or
its Lending Office to continue to perform its obligations to make Advances or to
continue to fund or maintain Advances and would not, in the judgment of such
Lender, be otherwise disadvantageous to such Lender. A certificate as to the
rate referred to in clause (ii) above submitted to the Borrower by such Lenders
shall be conclusive and binding for all purposes, absent manifest error.

     SECTION 2.10. Payments and Computations. (a) The Borrower shall make each
payment hereunder and under the Notes issued hereunder not later than 11:00 A.M.
(New York City time) on the day when due in U.S. dollars to the Administrative
Agent at the Administrative Agent's Account in same-day funds. The
Administrative Agent will promptly thereafter cause to be distributed like funds
relating to the payment of principal or interest or fees ratably (other than
amounts payable pursuant to Section 2.09, 2.11 or 8.04(c)) to the Lenders
entitled thereto for the account of their respective Lending Offices, and like
funds relating to the payment of any other amount payable to any Lender to such
Lender for the account of its Lending Office, in each case to be applied in
accordance with the terms of this Agreement. Upon its acceptance of an
Assignment and Acceptance and recording of the information contained therein in
the Register pursuant to Section 8.07(d), from and after the effective date
specified in such Assignment and Acceptance, the Administrative Agent shall make
all payments hereunder and under the Notes issued hereunder in respect of the
interest assigned thereby to the Lender assignee thereunder, and the parties to
such Assignment and Acceptance shall make all appropriate adjustments in such
payments for periods prior to such effective date directly between themselves
and the Borrower shall have no further obligation to such assignee with respect
to such adjustments.

     (b) Promptly on request by any Lender, the Borrower will deliver to such
Lender a Note payable to the order of such Lender.
<PAGE>

                                       38



     (c) All computations of interest based on the Base Rate shall be made by
the Administrative Agent on the basis of a year of 365 or 366 days, as the case
may be, and all computations of other interest and of fees shall be made by the
Administrative Agent on the basis of a year of 360 days, in each case for the
actual number of days (including the first day but excluding the last day)
occurring in the period for which such interest or fees are payable. Each
determination by the Administrative Agent of an interest rate hereunder shall be
conclusive and binding for all purposes, absent manifest error.

     (d) Whenever any payment hereunder or under the Notes issued hereunder
shall be stated to be due on a day other than a Business Day, such payment shall
be made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of payment of interest or commitment
fee, as the case may be; provided that, if such extension would cause payment of
interest on or principal of Advances to be made in the next following calendar
month, such payment shall be made on the next-preceding Business Day.

     (e) Unless the Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due to the Lenders hereunder
that the Borrower will not make such payment in full, the Administrative Agent
may assume that the Borrower has made such payment in full to the Administrative
Agent on such date and the Administrative Agent may, in reliance upon such
assumption, cause to be distributed to each Lender on such due date an amount
equal to the amount then due such Lender. If and to the extent the Borrower
shall not have so made such payment in full to the Administrative Agent, each
Lender shall repay to the Administrative Agent forthwith on demand such amount
distributed to such Lender together with interest thereon, for each day from the
date such amount is distributed to such Lender until the date such Lender repays
such amount to the Administrative Agent, at the Federal Funds Rate.

     (f) The obligation of the Borrower to make any payment under this Agreement
or any other Loan Document, including without limitation payments of principal,
interest, fees, costs and expenses due in accordance with the terms of the Loan
Documents, shall be unconditional and absolute, irrespective among other things
of the following:

          (i) any set-off, counterclaim, recoupment, deduction, abatement,
     suspension, diminution, reduction, defense or other right that the Borrower
     may have against the Vendor at any time for any reason whatsoever arising
     under or pursuant to the Supply Agreement or otherwise relating to the
     purchase of goods, equipment, other property or services from or by the
     Vendor;

          (ii) any defect in the condition, design, operation or fitness for use
     of, or any damage to or loss or destruction of, any equipment or material
     provided by the Vendor;
<PAGE>

                                       39



          (iii) any actual or alleged default by the Vendor or any other Person
     under the Supply Agreement; or

          (iv) any other fact or circumstance relating to the Supply Agreement.

     SECTION 2.11. Taxes. (a) Any and all payments by the Borrower hereunder or
under the Notes issued hereunder shall be made, in accordance with Section 2.10,
free and clear of and without deduction for any and all present or future taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, excluding, in the case of each Lender and the Administrative
Agent, taxes that are imposed on its overall net income by the United States and
taxes that are imposed on its overall net income (and franchise taxes imposed in
lieu thereof) by the state or foreign jurisdiction under the laws of which such
Lender or the Administrative Agent (as the case may be) is organized or any
political subdivision thereof and, in the case of each Lender, taxes that are
imposed on its overall net income (and franchise taxes imposed in lieu thereof)
by the state or foreign jurisdiction of such Lender's Lending Office or any
political subdivision thereof (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities in respect of payments
hereunder or under the Notes being hereinafter referred to as "Taxes"). If the
Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder or under any Note to any Lender or the Administrative
Agent, (i) the sum payable shall be increased as may be necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section 2.11) such Lender or the Administrative Agent
(as the case may be) receives an amount equal to the sum it would have received
had no such deductions been made, (ii) the Borrower shall make such deductions
and (iii) the Borrower shall pay the full amount deducted to the relevant
taxation authority or other authority in accordance with applicable law.

     (b) In addition, the Borrower shall pay any present or future stamp,
documentary, excise, property or similar taxes, charges or levies that arise
from any payment made hereunder or under the Notes or from the execution,
delivery or registration of, performing under, or otherwise with respect to,
this Agreement, the Notes or the other Loan Documents (hereinafter referred to
as "Other Taxes").

     (c) The Borrower shall indemnify each Lender and the Administrative Agent
for and hold it harmless against the full amount of Taxes or Other Taxes
(including without limitation taxes of any kind imposed by any jurisdiction on
amounts payable under this Section 2.11) imposed on or paid by such Lender or
the Administrative Agent (as the case may be) and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto.
This indemnification shall be made within 30 days from the date such Lender or
the Administrative Agent (as the case may be) makes written demand therefor.

     (d) Within 60 days after the date of any payment of Taxes, the Borrower
shall furnish to the Administrative Agent, at its address referred to in Section
8.02, the original or a
<PAGE>

                                       40



certified copy of a receipt evidencing such payment. In the case of any payment
hereunder or under the Notes by or on behalf of the Borrower through an account
or branch outside the United States or by or on behalf of the Borrower by a
payor that is not a United States person, if the Borrower determines that no
Taxes are payable in respect thereof, the Borrower shall furnish, or shall cause
such payor to furnish, to the Administrative Agent, at such address, an opinion
of counsel acceptable to the Administrative Agent stating that such payment is
exempt from Taxes. For purposes of this subsection (d) and subsection (e), the
terms "United States" and "United States person" shall have the meanings
specified in Section 7701 of the Internal Revenue Code or (in the case of a
Lender that has certified in writing to the Administrative Agent that it is not
a "bank" as defined in Section 881(c)(3)(A) of the Internal Revenue Code) form
W-8 (and, if such Lender delivers a form W-8, a certificate representing that
such Lender is not a "bank" for purposes of Section 881(c) of the Internal
Revenue Code, is not a 10-percent shareholder (within the meaning of Section
871(h)(3)(B) of the Internal Revenue Code) of the Borrower and is not a
controlled foreign corporation related to the Borrower (within the meaning of
Section 864(d)(4) of the Internal Revenue Code)), as appropriate, or any
successor or other form prescribed by the Internal Revenue Service, certifying
that such Lender is exempt from or entitled to a reduced rate of United States
withholding tax on payments pursuant to this Agreement or the Notes or, in the
case of a Lender providing a form W-8, certifying that such Lender is a foreign
corporation, partnership, estate or trust. If the forms provided by a Lender at
the time such Lender first becomes a party to this Agreement indicates a United
States interest withholding tax rate in excess of zero, withholding tax at such
rate shall be considered excluded from Taxes unless and until such Lender
provides the appropriate form certifying that a lesser rate applies, whereupon
withholding tax at such lesser rate only shall be considered excluded from Taxes
for periods governed by such form; provided that, if at the date of the
Assignment and Acceptance pursuant to which a Lender becomes a party to this
Agreement, the Lender assignor was entitled to payments under subsection (a) in
respect of United States withholding tax with respect to interest paid at such
date, then, to such extent, the term Taxes shall include (in addition to
withholding taxes that may be imposed in the future or other amounts otherwise
includable in Taxes) United States withholding tax, if any, applicable with
respect to the Lender assignee on such date. If any form or document referred to
in this subsection (d) requires the disclosure of information, other than
information necessary to compute the tax payable and information required on the
date hereof by Internal Revenue Service form 1001, 4224 or W-8 (or the related
certificate described above), that the Lender reasonably considers to be
confidential, the Lender shall give notice thereof to the Borrower and shall not
be obligated to include in such form or document such confidential information.

     (e) For any period with respect to which a Lender has failed to provide the
Borrower with the appropriate form described in Section 2.11(d) (other than if
such failure is due to a change in law occurring subsequent to the date on which

required under subsection (d) above), such Lender shall not be entitled to
indemnification under Section 2.11(a) or (c) with respect to Taxes imposed by

subject to Taxes because of its failure to deliver a form required
hereunder, the Borrower shall take such steps as the Lender shall reasonably
request to assist the Lender to recover such Taxes.

     SECTION 2.12. Sharing of Payments, Etc. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the Advances owing to it (other than
pursuant to Section 2.09, 2.11 or 8.04(c)) in excess of its ratable share of
payments on account of the Advances obtained by all the Lenders, such Lender
shall forthwith purchase from the other Lenders such participations in the
Advances owing to them as shall be necessary to cause such purchasing Lender to
share the excess payment ratably with each of them; provided that if all or any
portion of such excess payment is thereafter recovered from such purchasing
Lender, such purchase from each Lender shall be rescinded and such Lender shall
repay to the purchasing Lender the purchase price to the extent of such recovery
together with an amount equal to such Lender's ratable share (according to the
proportion of (a) the amount of such Lender's required repayment to (b) the
total amount so recovered from the purchasing Lender) of any interest or other
amount paid or payable by the purchasing Lender in respect of the total amount
so recovered. The Borrower agrees that any Lender so purchasing a participation
from another Lender pursuant to this Section 2.12 may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Lender were the
direct creditor of the Borrower in the amount of such participation. With
respect to any reduction or termination of Commitments pursuant to Section 2.04,
the reduction or termination of the Commitments shall be made ratably among the
Commitments of all Lenders outstanding at the time of such reduction or
termination. With respect to any repayment or prepayment made by the Borrower
hereunder other than scheduled amortization pursuant to Section 2.05, such
repayment or prepayment shall be distributed ratably among all Lenders in
proportion with the principal amount of the Advances held by each such Lender
outstanding at the time of such repayment or prepayment. With respect to any
repayment of scheduled amortization made by the Borrower hereunder pursuant to
Section 2.05, such repayments shall be distributed ratably among all Lenders of
the relevant tranche in proportion with the principal amount of the Advances of
such tranche held by each such Lender of outstanding at the time of such
repayment or prepayment.

     SECTION 2.13. Use of Proceeds. The proceeds of the Advances shall be
available to the Borrower and its Subsidiaries, directly or indirectly, solely
(a) to make Back-to-Back Loans that shall be used by Operating Subsidiaries to
purchase telecommunications equipment, software, engineering and other services
(i) pursuant to or in accordance with the Supply Agreement and subject to the
limitations set forth therein for the purpose of planning, constructing,
operating and maintaining Networks in the Core Territories and (ii) described in
the letter dated June 18, 1999 from LM Ericsson Telefonaktiebolaget to the
Borrower, (b) to pay interest payable to the Lenders on each interest payment
date occurring on or prior to the first anniversary of the Amendment Effective
Date and (c) to pay fees payable pursuant to Section 2.03 and expenses payable
pursuant to Section 8.04(a)(i)(A) and (B), in each case with respect to the
Lenders. The proceeds of all Advances to be used as described in clause (a) of
the preceding
<PAGE>

                                       42



sentence shall be paid directly to the financial institution providing
Back-to-Back Loans and the proceeds of such Back-to-Back Loans made to Operating
Subsidiaries in Argentina, Brazil and Peru shall at all times be held in Blocked
Accounts until disbursed to pay invoices under the Supply Agreement.

     SECTION 2.14. First Eurodollar Method and Second Eurodollar Method. The
First Eurodollar Method shall be applicable at all times until such time as the
Second Eurodollar Method becomes applicable. If there is a Lender in addition to
or other than the Initial Lender (other than an Affiliate of the Initial Lender)
and the Administrative Agent at the direction of any Lender shall have notified
the Borrower that the Second Eurodollar Method shall be applicable, the Second
Eurodollar Method shall become applicable immediately as of the date of such
notice for all new Advances made as of and following the date of such notice.
After becoming applicable, the Second Eurodollar Method shall remain applicable
at all times thereafter.

     SECTION 2.15. Redistribution of Payments. In the event that a repayment
under Section 2.05 or a prepayment under Section 2.08 is required to be
redistributed by the Lenders to the lenders (the "Other Lenders") under another
Permitted Loan Agreement (as defined in the Intercreditor Agreement) pursuant to
Section 4.2 or 4.3 of the Intercreditor Agreement, (i) the Borrower authorizes
the Lenders to act as its agent in connection with such redistribution and make
such redistribution to the Other Lenders on its behalf and acknowledges that any
amount so redistributed shall be deemed not to have been paid by the Borrower to
the Lenders in their capacity as Lenders hereunder and (ii) the Lenders agree to
act as agent for the Borrower in connection with such redistribution and agree
to make such redistribution to the Other Lenders on its behalf. In the event
that a repayment or prepayment made by the Borrower pursuant to another
Permitted Loan Agreement to the Other Lenders party thereto is required to be
redistributed by such Other Lenders pursuant to Section 4.2 or 4.3 of the
Intercreditor Agreement, the Lenders acknowledge that any amount so
redistributed (I) shall have been paid by the Other Lenders acting as agent for
the Borrower in connection with such redistribution, (II) shall be deemed to
have been paid by the Borrower to the Lenders in respect of the Advances
pursuant to Section 2.05 or 2.08, as the case may be, and (III) shall be
allocated among the Lenders in accordance with Section 2.12.

     terms except as such enforceability may be limited by (i) applicable
     bankruptcy, insolvency, liquidation, fraudulent conveyance, reorganization,
     concordato, moratorium or similar laws now or hereafter in effect affecting
     the enforcement of creditors' rights generally and (ii) general principles
     of equity (regardless of whether such enforceability is considered in a

     the results of operations of the Borrower for the period ended on such
     date, all in accordance with generally accepted accounting principles
     applied on a consistent basis. The Consolidated forecasted balance sheets,
     income statements and cash flow statements of the Borrower and its
     Subsidiaries delivered to the Lenders in connection with the Project were

     such Consolidated forecasted balance sheets, income statements and cash
     flow statements shall be construed as a representation, warranty, covenant,
     undertaking, guaranty or assurance by the Borrower or any of its
     Subsidiaries as to the future financial or business performance of the
     Borrower and its Subsidiaries and that the forward-looking statements
     contained in such Consolidated forecasted balance sheets, income statements
     and cash flow statements involve known and unknown risks, contingencies,
     uncertainties and other factors that may cause the actual results, events
     or developments pertaining to the Borrower and its Subsidiaries to be
     materially and adversely different from any future results, events or
     developments contemplated, expressed or implied by such Consolidated
     forecasted balance sheets, income statements and cash flow statements.
     Since September 30, 1999, there has been no Material Adverse Change.

          (i) No information, exhibit or report furnished in writing by (or on
     behalf of) the Borrower to the Administrative Agent, the Collateral Agent

     pursuant to the terms of the Loan Documents contained at the time when

     material fact necessary to make the statements made therein (taken as a
     whole) not misleading.

     pending or, to the best of the Borrower's knowledge, threatened action,

     litigation or proceeding, including without limitation any Environmental
     Action, affecting the Borrower or any of its Subsidiaries before any court,
     governmental agency or arbitrator that (i) could be reasonably likely to
     have a Material Adverse Effect or (ii) purports to affect the legality,
     validity or enforceability of any Loan Document or the consummation of the
     transactions contemplated hereby or thereby, and there has been no material
     adverse change in the status, or financial effect on the Borrower or any of
     its Subsidiaries, of the Disclosed Litigation from that described on
     Schedule 3.01(a)(i) hereto.

          (k) The Borrower is not engaged in the business of extending credit

     Stock.

          (l) The operations and properties of the Borrower and Subsidiaries
     comply in all material respects with all applicable Environmental Laws and
     Environmental Permits, except where the failure to be in such compliance
     could not reasonably be expected to have a Material Adverse Effect.

          (m) The Borrower and each of its Subsidiaries has filed, has caused to
     be filed or has been included in all tax returns (national, departmental,
     local, municipal and foreign) required to be filed and has paid or caused

     payment of any taxes, assessment, fees or other charges (i) the nonpayment
     of which would not have a Material Adverse Effect or (ii) that are being
     contested in good faith and by proper proceedings and for which appropriate
     reserves are being maintained.

          (n) The obligations of the Borrower and each of its Subsidiaries under

     to be a party constitute direct, unconditional and unsubordinated

     expected to have a Material Adverse Effect.

     and the Project.

          (aa) The activities of the Borrower's Subsidiaries contemplated by the
     Project and this Agreement are commercial in nature rather than

     per US$1000.00 of face value would be payable on the Credit Agreement and
     the Security Agreements at the time of enforcement in a Panama court should
     this take place; and (E) in the case of Peru, payments of interest, fees,

          deliver any and all further instruments and documents and take all
          such other action as either Agent may deem desirable in obtaining the
          full benefits of or in preserving the Liens of each Security Agreement

     the Loan Documents against the Loan Parties in such jurisdictions,
     including without limitation the consularization of the Loan Documents
     where the laws of the relevant Core Territory may so require.

          (q) Additional Collateral. To the extent the cost of creating,
     perfecting and maintaining a Lien on any such Collateral does not,
     individually or in the aggregate, exceed the value of any recovery proceeds
     reasonably expected to be obtained by the Collateral Agent in connection
     with the enforcement of such Lien against such Collateral, within 30 days
     after delivering the report required pursuant to Section 5.03(t) with
     respect to additional Collateral, cause such relevant Operating Subsidiary,
     at its expense, to assign and pledge to the Collateral Agent for the
     benefit of the Secured Creditors the property described in such report,

          (b) any representation or warranty made by any Loan Party (or any of
     its officers) in connection with any Loan Document shall prove to have been
     incorrect in any material respect when made; provided that, if such
     inaccuracy is capable of remedy and is in respect of any representation and
     warranty other than those contained in Sections 4.01(a), (b), (c), (d),
     (g), (h), (i), (j), (k), (n) and (y), such inaccuracy shall continue
     unremedied for a period of 10 days; or

               (i) the Borrower shall fail to perform or observe any term,
          covenant or agreement contained in Section 2.13, 5.01(e), (f), (k) or
          (n), 5.02 or 5.04, or

          material adverse effect on the ability of the Borrower to perform its
          payment obligations under the Loan Documents;

               (ii) any rights of the Borrower or any of its Subsidiaries
          thereunder shall be changed and such change is reasonably likely to

               (iii) any proceeding shall be commenced with the intention of
          revoking the Licenses or a portion thereof that (A) has a reasonable
          likelihood of succeeding and could reasonably be expected to prevent
          the Borrower from operating a material portion of its Network or does
          succeed in revoking all of the Licenses or (B) could reasonably be
          expected to result in or which actually results in, a material adverse
          effect on the ability of the Borrower to perform its payment
          obligations under the Loan Documents; or

               (iv) any Core Territory shall impose any obligation on the
          Borrower or any of its Subsidiaries in respect of any License that is

          the Borrower to perform its payment obligations under the Loan
          Documents; or

          (f) either:

               (i) the Borrower or any of its Subsidiaries shall fail to pay (A)

          in respect of any Debt or (B) any principal of any Subordinated Debt
          or Intercompany Mirror Subordinated Debt, in each case that is
          outstanding in a principal or notional amount of at least $5,000,000
          in the aggregate (but excluding Debt outstanding hereunder) of the
          Borrower or such Subsidiary (as the case may be), when the same
          becomes due and payable (whether by scheduled maturity, required
          prepayment, acceleration, demand or otherwise), and such failure shall
          continue

          after the applicable grace period, if any, specified in the agreement
          or instrument relating to such Debt; or any other event shall occur or
          condition shall exist under any agreement or instrument relating to
          any such Debt and shall continue after the applicable grace period, if
          any, specified in such agreement or instrument, if the effect of such
          event or condition is to accelerate, or to permit the acceleration of,
          the maturity of such Debt; or any such Debt shall be declared to be
          due and payable, or required to be prepaid or redeemed (other than by

          scheduled maturity, required prepayment, acceleration, demand or
          otherwise), and such failure shall continue after the applicable grace
          period, if any, specified in the agreement or instrument relating to
          such Debt; or any other event shall occur or condition shall exist
          under any agreement or instrument relating to any such Debt and shall
          continue after the applicable grace period, if any, specified in such
          agreement or instrument, if the effect of such event or condition is
          to accelerate the maturity of such Debt; or any such Debt shall be
          declared to be due and payable, or required to be prepaid or redeemed

          (g) the Parent or any Loan Party shall generally not pay its debts as
     such debts become due, or shall admit in writing its inability to pay its
     debts generally, or shall make a general assignment for the benefit of

     instituted by it) that is being diligently contested by it in good faith,
     either such proceeding shall remain undismissed, unvacated or unstayed for
     a period of 60 days, or any of the actions sought in such proceeding
     (including without limitation the entry of an order for relief against, or
     the appointment of a receiver, trustee, custodian or other similar official
     for, it or for any substantial part of its property) shall occur; or the

                                   ARTICLE VII

                            THE ADMINISTRATIVE AGENT

     SECTION 7.01. Authorization and Action. Each Lender hereby appoints and
authorizes the Administrative Agent to take such action as agent on its behalf
and to exercise such powers and discretion under this Agreement as are delegated
to the Administrative Agent by the terms hereof, together with such powers and
discretion as are reasonably incidental thereto. As to any matters not expressly
provided for by this Agreement (including without limitation enforcement or
collection of the Notes), the Administrative Agent shall not be required to
exercise any discretion or take any action, but shall be required to act or to
refrain from acting (and shall be fully protected in so acting or refraining
from acting) upon the instructions of the Required Lenders, and such
instructions shall be binding upon all Lenders and all holders of Notes;
provided that the Administrative Agent shall not be required to take any action
that exposes the Administrative Agent to personal liability or that is contrary
to this Agreement or applicable law. The Administrative Agent agrees to give to
each Lender prompt notice of each notice given to it by the Borrower pursuant to
the terms of this Agreement.

     SECTION 7.02. Agent's Reliance, Etc. Neither the Administrative Agent nor
any of its respective directors, officers, agents or employees shall be liable
for any action taken or omitted to be taken by it or them under or in connection
with this Agreement, except for its or their own gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, the
Administrative Agent: (i) may treat the payee of any Note as the holder thereof
until the Administrative Agent receives and accepts an Assignment and Acceptance
entered into by the Lender that is the payee of such Note, as assignor, and an
Eligible Assignee, as assignee, as provided in Section 8.07; (ii) may consult
with legal counsel (including counsel for the Borrower), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken in good faith by it in accordance with the
advice of such counsel, accountants or experts; (iii) makes no warranty or
representation to any Lender and shall not be responsible to any Lender for any
statements, warranties or representations (whether written or oral) made in or
in connection with this Agreement; (iv) shall not have any duty to ascertain or
to inquire as to the performance or observance of any of the terms, covenants or
conditions of this Agreement on the part of the Borrower or to inspect the
property (including the books and records) of the Borrower; (v) shall not be
responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of, or the perfection or
priority of any lien or security interest created or purported to be created
under or in connection with, this Agreement or any other instrument or document
furnished pursuant hereto; and (vi) shall incur no liability under or in respect
of this Agreement by acting upon any notice, consent, certificate or other
instrument or writing (which may be by telecopier, telegram or telex) believed
by it to be genuine and signed or sent by the proper party or parties.

     SECTION 7.03. Agent and Affiliates. With respect to its Commitment, the
Advances made by it and the Note issued to it, if any, the Person serving as the
Administrative Agent hereunder shall have the same rights and powers under this
Agreement as any other Lender and may exercise the same as though it were not
the Administrative Agent; and the term
<PAGE>

                                       85



"Lender" or "Lenders" shall, unless otherwise expressly indicated, include the
Administrative Agent in its individual capacity. Any Person serving as
Administrative Agent and its Affiliates may accept deposits from, lend money to,
act as trustee under indentures of, accept investment banking engagements from
and generally engage in any kind of business with, the Borrower, any of its
Subsidiaries and any Person who may do business with or own securities of the
Borrower or any such Subsidiary, all as if the Person serving as Administrative
Agent were not the Administrative Agent and without any duty to account therefor
to the Lenders.

     SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent or any other
Lender and based on the financial statements referred to in Section 4.01 and
such other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement.

     SECTION 7.05. Indemnification. The Lenders agree to indemnify the
Administrative Agent (to the extent not reimbursed by the Borrower), ratably
according to the respective principal amounts of the Notes then held by each of
the Lenders (or if no Notes are at the time outstanding or if the Notes are held
by Persons that are not Lenders, ratably according to the respective amounts of
their Commitments), from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever that may be imposed on, incurred
by, or asserted against the Administrative Agent, in any way relating to or
arising out of this Agreement or any action taken or omitted by the
Administrative Agent under this Agreement (collectively, the "Indemnified
Costs"); provided that no Lender shall be liable for any portion of the
Indemnified Costs resulting from the gross negligence or willful misconduct of
the Administrative Agent. Without limitation of the foregoing, each Lender
agrees to reimburse the Administrative Agent promptly upon demand for its
ratable share of any out-of-pocket expenses (including counsel fees) incurred by
it in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, to the extent that such agent is not
reimbursed for such expenses by the Borrower. In the case of any investigation,
litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05
applies whether any such investigation, litigation or proceeding is brought by
the Administrative Agent, any Lender or a third party.

     SECTION 7.06. Successor Agent. The Administrative Agent may resign at any
time by giving written notice thereof to the Lenders and the Borrower and may be
removed at any time with or without cause by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a
successor Administrative Agent. If no
<PAGE>

                                       86



successor Administrative Agent shall have been so appointed by the Required
Lenders, and shall have accepted such appointment, within 30 days after such
retiring agent's giving of notice of resignation or the Required Lenders'
removal of such retiring agent, then such retiring agent may, on behalf of the
Lenders, appoint a successor Administrative Agent, which shall be a commercial
bank organized or licensed to do business under the laws of the United States of
America or of any State thereof and having a combined capital and surplus of at
least $1,000,000,000. Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor Administrative Agent, such successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, discretion, privileges and duties of the retiring Administrative
Agent and the retiring Administrative Agent shall be discharged from its duties
and obligations under this Agreement. After any such retiring agent's
resignation or removal hereunder as Administrative Agent, the provisions of this
Article VII shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Administrative Agent under this Agreement.


                                  ARTICLE VIII

                                  MISCELLANEOUS

     SECTION 8.01. Amendments, Etc. No amendment or waiver of any provision of
this Agreement or the Notes, nor consent to any departure by the Borrower
therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Required Lenders, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided that

          (a) no amendment, waiver or consent shall, unless in writing and
     signed by all of the Lenders (other than any Lender Party that is, at such
     time, a Defaulting Lender), do any of the following at any time:

          of them to take any action hereunder,

               (iii) reduce or limit the obligations of any Guarantor under

     SECTION 8.03. No Waiver; Remedies. No failure on the part of any Lender,
the Administrative Agent or the Collateral Agent to exercise, and no delay in

remedies herein provided are cumulative and not exclusive of any remedies
provided by law.

     SECTION 8.04. Costs and Expenses; Indemnification. (a) The Borrower will
pay on demand

          (i) all costs and expenses of the Administrative Agent and the Lenders
     in connection with the preparation, execution, delivery, administration,
     modification and amendment of the Loan Documents (including, without
     limitation, (A) all due diligence, collateral review, syndication,
     transportation, computer, duplication, appraisal, audit, insurance,
     consultant, search, filing and recording fees and expenses, (B) the
     reasonable fees and expenses of a single counsel for the Agents in each
     relevant jurisdiction with respect thereto, and (C) the reasonable fees and
     expenses of a single counsel for the Agents in each relevant jurisdiction
     with respect to advising the Agents as to their respective rights and
     responsibilities, or the perfection, protection or preservation of rights
     or interests, under the Loan Documents, with respect to negotiations with
     any Loan Party or with other creditors of any Loan Party or any of its
     Subsidiaries arising out of any Default or any events or circumstances that
     may give rise to a Default and with respect to presenting claims in or
     otherwise participating in or monitoring any bankruptcy, insolvency or
     other similar proceeding involving creditors' rights generally and any
     proceeding ancillary thereto), and

          (ii) all costs and expenses of the Administrative Agent and the Lender
     Parties in connection with the enforcement of the Loan Documents, whether
     in any action, suit or litigation, any bankruptcy, insolvency or other
     similar proceeding affecting creditors' rights generally (including,
     without limitation, the reasonable fees and expenses of a single counsel
     for the Administrative Agent and each Lender Party in each relevant
     jurisdiction with respect thereto).

     (b) The Borrower will indemnify and hold harmless the Administrative Agent
and each Lender and each of their Affiliates and their officers, directors,
employees, agents and advisors (each, an "Indemnified Party") from and against
any and all claims, damages, losses, liabilities and expenses (including without
limitation reasonable fees and expenses of counsel) that may be incurred by or
asserted or awarded against any Indemnified Party, in each case arising in any
way out of or in connection with or by reason of (i) the Notes, this Agreement,
any of the transactions contemplated herein or the actual or proposed use of the
proceeds of the Advances, except to the extent such claim, damage, loss,
liability or expense resulted from such
<PAGE>

                                       89



Indemnified Party's gross negligence or willful misconduct. In the case of an
investigation, litigation or other proceeding to which the indemnity in this
Section 8.04(b) applies, such indemnity shall be effective whether or not such
investigation, litigation or proceeding is brought by the Borrower, its
directors, shareholders or creditors or an Indemnified Party or any other Person
or any Indemnified Party is otherwise a party thereto and whether or not the
transactions contemplated hereby are consummated. The Borrower also agrees not
to assert any claim against the Agent, any Lender, any of their Affiliates, or
any of their respective directors, officers, employees, attorneys and agents, on
any theory of liability, for special, indirect, consequential or punitive
damages arising out of or otherwise relating to the Notes, this Agreement, any
of the transactions contemplated herein or the actual or proposed use of the
proceeds of the Advances.

     (c) If any payment of principal of any Advance is made by the Borrower to
or for the account of a Lender other than on the last day of the Interest Period
for such Advance, as a result of a payment pursuant to Section 2.09(c) and (d),
acceleration of the maturity of the Notes pursuant to Section 6.01 or for any
other reason, the Borrower shall, upon written demand by such Lender (with a
copy of such demand to the Administrative Agent), pay to the Administrative
Agent for the account of such Lender any amounts reasonably required to
compensate such Lender for any additional losses, costs or expenses that it may
reasonably incur as a result of such payment, including without limitation any
loss, cost or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by any Lender to fund or maintain such Advance.
The loss to any Lender attributable to any such event shall be deemed to be an
amount determined by such Lender to be equal to the excess, if any, of (i) the
amount of interest that such Lender would pay for a deposit equal to the
principal amount of the applicable Eurodollar Rate Advance so prepaid or
accelerated, as applicable, for the period from the date of such payment or
acceleration to the last day of the then current Interest Period for such
Eurodollar Rate Advance if the interest rate payable on such deposit were equal
to the Eurodollar Rate for such Interest Period, over (ii) the amount of
interest that such Lender would earn on such principal amount for such period if
such Lender were to invest such principal amount for such period at the interest
rate that would be bid by such Lender (or an Affiliate of such Lender) for
dollar deposits from other banks in the eurodollar market at the commencement of
such period. A certificate as to the amount of such loss, cost or expense,
submitted to the Borrower by such Lender, shall be conclusive and binding for
all purposes, absent manifest error.

     (d) If any Loan Party fails to pay when due any costs, expenses or other
amounts payable by it under any Loan Document, including, without limitation,
fees and expenses of counsel and indemnities, such amount may be paid on behalf
of such Loan Party by the Agents or any Lender Party, in its sole discretion.

     (e) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
Sections 2.09, 2.11 and 8.04 shall survive the payment in full of principal,
interest and all other amounts payable hereunder and under the Notes.

     SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during the
continuance of any Event of Default and (ii) the making of the request or the
granting of the consent specified by Section 6.01 to authorize the
Administrative Agent to declare the Notes due and payable pursuant to the
provisions of Section 6.01, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any
time owing by such Lender or such Affiliate to or for the credit or the account
of the Borrower against any and all of the obligations of the Borrower now or
hereafter existing under this Agreement and the Note held by such Lender,
whether or not such Lender shall have made any demand under this Agreement or
such Note and although such obligations may be unmatured. Each Lender agrees
promptly to notify the Borrower in writing after any such set-off and
application; provided that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of each Lender and its
Affiliates under this Section 8.05 are in addition to other rights and remedies
(including without limitation other rights of set-off) that such Lender and its
Affiliates may have.

     SECTION 8.06. Binding Effect. The amendment and restatement of the Original
Credit Agreement, as set forth in this Agreement, shall become effective when
(i) this Agreement shall have been executed by the Borrower, the Administrative
Agent and the Initial Lender and (ii) the conditions set forth in Section 3.03
shall have been fulfilled and thereafter this Agreement shall be binding upon
and inure to the benefit of the Borrower, the Administrative Agent and each
Lender and their respective successors and assigns, except that the Borrower
shall not have the right to assign its rights hereunder or any interest herein
without the prior written consent of the Lenders.

     SECTION 8.07. Assignments and Participations. (a) Each Lender may assign to
an Eligible Assignee all or a portion of its rights and obligations under this
Agreement (including without limitation all or a portion of its Commitment, the
Advances owing to it and the Note or Notes held by it and either outstanding
Advances or Commitments); provided that (i) except in the case of an assignment
to a Person that, immediately prior to such assignment, was a Lender or an
assignment of all of a Lender's rights and obligations under this Agreement, the
amount of the Advances and unfunded Commitment of the assigning Lender being
assigned pursuant to each such assignment (determined as of the date of the
Assignment and Acceptance with respect to such assignment) shall in no event be
less than $5,000,000 and (ii) the parties to each such assignment shall execute
and deliver to the Administrative Agent, for its acceptance and recording in the
Register, an Assignment and Acceptance, together with any Note subject to such
assignment and a processing and recordation fee of $3,500. Notwithstanding the
foregoing, nothing in this Section shall be construed to prohibit the assignment
of a proportionate part of all of the assigning Lender's rights and obligations
in respect of (A) Advances separately from (or without assigning) Commitments,
(B) Commitments separately from (or without assigning) Advances, (C) Tranche A
Commitments or Tranche A Advances separately from (or without assigning) Tranche
B Commitments or Tranche B Advances or (D) Tranche B Commitments or Tranche B
Advances separately from (or without assigning) Tranche A Commitments or Tranche
A Advances. Upon such execution, delivery, acceptance and recording, from and
after the
<PAGE>

                                       91



effective date specified in each Assignment and Acceptance, (x) the assignee
thereunder shall be a party hereto and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such Assignment and
Acceptance, have the rights and obligations of a Lender hereunder and (y) the
Lender assignor thereunder shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such Assignment and Acceptance,
relinquish its rights and be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining
portion of an assigning Lender's rights and obligations under this Agreement,
such Lender shall upon such assignment cease to be a party hereto).

     (b) By executing and delivering an Assignment and Acceptance, the Lender
assignor thereunder and the assignee thereunder confirm to and agree with each
other and the other parties hereto as follows: (i) other than as provided in
such Assignment and Acceptance, such assigning Lender makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of, or the perfection or priority of any lien or security interest created
or purported to be created under or in connection with, this Agreement or any
other instrument or document furnished pursuant hereto; (ii) such assigning
Lender makes no representation or warranty and assumes no responsibility with
respect to the financial condition of the Borrower or the performance or
observance by the Borrower of any of its obligations under this Agreement or any
other instrument or document furnished pursuant hereto; (iii) such assignee
confirms that it has received a copy of this Agreement and the Intercreditor
Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (iv) such assignee will, independently and without
reliance upon the Administrative Agent, such assigning Lender or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement; (v) such assignee confirms that it is an Eligible
Assignee; (vi) such assignee appoints and authorizes the Administrative Agent
and the Collateral Agent to take such action as agent on its behalf and to
exercise such powers and discretion under this Agreement as are delegated to the
Administrative Agent and the Collateral Agent by the terms hereof, together with
such powers and discretion as are reasonably incidental thereto; and (vii) such
assignee agrees that it will perform in accordance with their terms all of the
obligations that by the terms of this Agreement and the Intercreditor Agreement
are required to be performed by it as a Lender.

     (c) The Administrative Agent shall maintain at its address referred to in
Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted
by it and a register for the recordation of the names and addresses of the
Lenders and the Commitment of, and principal amount of the Advances owing to,
each Lender from time to time (the "Register"). The entries in the Register
shall be conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Administrative Agent, the Collateral Agent and the Lenders may
treat each Person whose name is recorded in the Register as a Lender hereunder
for all purposes
<PAGE>

                                       92



of this Agreement. The Register shall be available for inspection by the
Borrower or any Lender at any reasonable time and from time to time upon
reasonable prior notice.

     (d) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee representing that it is an Eligible Assignee,
together with any Note or Notes subject to such assignment, the Administrative
Agent shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit C, (i) accept such Assignment and Acceptance,
(ii) record the information contained therein in the Register and (iii) give
prompt written notice thereof to the Borrower. Within five Business Days after
its receipt of such notice and at the request of such assignee Lender, the
Borrower, at its own expense, shall execute and deliver to the Administrative
Agent in exchange for any surrendered Note a new Note to the order of such
Assignee in an amount equal to the Commitment assumed by it pursuant to such
Assignment and Acceptance and, if the assigning Lender has retained a Commitment
hereunder, a new Note to the order of the assigning Lender in an amount equal to
the Commitment retained by it hereunder. Such new Note or Notes shall be in an
aggregate principal amount equal to the aggregate principal amount of such
surrendered Note or Notes, shall be dated the effective date of such Assignment
and Acceptance and shall otherwise be in substantially the form of Exhibit A.

     (e) Each Lender may sell participations to one or more banks or other
entities (other than the Borrower or any of its Affiliates) in or to all or a
portion of its rights and obligations under this Agreement (including without
limitation all or a portion of its Commitment, the Advances owing to it and the
Note or Notes held by it); provided that (i) such Lender's obligations under
this Agreement (including without limitation its Commitment to the Borrower
hereunder) shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Lender shall remain the holder of any such Note for all purposes of
this Agreement, (iv) the Borrower, the Administrative Agent, the Collateral
Agent and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement and (v) no participant under any such participation shall have any
right to approve any amendment or waiver of any provision of this Agreement or
any Note, or any consent to any departure by the Borrower therefrom, except to
the extent that such amendment, waiver or consent would reduce the principal of,
or interest on, the Notes or any fees or other amounts payable hereunder, in
each case to the extent subject to such participation, postpone any date fixed
for any payment of principal of, or interest on, the Notes or any fees or other
amounts payable hereunder, in each case to the extent subject to such
participation, or to the extent that any such amendment or consent provides for
a release of the Borrower's obligations under the Security Agreements or any
Subsidiary's obligations under any Guaranty.

     (f) Any Lender may, in connection with any assignment or participation or
proposed assignment or participation pursuant to this Section 8.07, disclose to
the assignee or participant or proposed assignee or participant, any information
relating to the Borrower furnished to such Lender by or on behalf of the
Borrower; provided that, prior to any such disclosure, the assignee or
participant or proposed assignee or participant shall agree in writing to
<PAGE>

                                       93



preserve the confidentiality of any Confidential Information relating to the
Borrower received by it from such Lender.

     (g) Notwithstanding any other provision set forth in this Agreement, any
Lender may at any time create a security interest in all or any portion of its
rights under this Agreement (including without limitation the Advances owing to
it and the Note held by it) in favor of any Federal Reserve Bank in accordance
with Regulation A of the Board of Governors of the Federal Reserve System.

     SECTION 8.08. Confidentiality. Neither the Administrative Agent nor any
Lender shall disclose any Confidential Information to any other Person without
the consent of the Borrower, other than (a) to the Administrative Agent's, the
Collateral Agent or such Lender's Affiliates and their officers, directors,
employees, agents and advisors and, as contemplated by Section 8.07(f), to
actual or prospective assignees and participants, and then only on a
confidential basis, (b) to any party to the Intercreditor Agreement, (c) as
required by any law, rule or regulation or judicial process and (d) as requested
or required by any state, federal or foreign authority or examiner regulating
banks or banking.

     SECTION 8.09. Governing Law. This Agreement and the Notes shall be governed
by, and construed in accordance with, the laws of the State of New York.

     SECTION 8.10. Execution in Counterparts. This Agreement may be executed in
any number of counterparts and by different 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.
Delivery of an executed counterpart of a signature page to this Agreement by
telecopier shall be effective as delivery of a manually executed counterpart of
this Agreement.

     SECTION 8.11. Jurisdiction, Judgment Currency, Etc. (a) Each of the parties
hereto hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
federal court of the United States of America sitting in New York City in the
Borough of Manhattan, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to this Agreement or the Notes, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in any such New York State
court or, to the extent permitted by law, in such federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement shall
affect any right that any party may otherwise have to bring any action or
proceeding relating to this Agreement or the Notes in the courts of any
jurisdiction.

     (b) Each of the parties hereto irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection that it
may now or hereafter have
<PAGE>

                                       94



to the laying of venue of any suit, action or proceeding arising out of or
relating to this Agreement or the Notes in any New York State or federal court.
Each of the parties hereto hereby irrevocably waives, to the fullest extent
permitted by law, the defense of an inconvenient forum to the maintenance of
such action or proceeding in any such court.

     (c) (i) If, for the purpose of obtaining judgment in any court, it is
necessary to convert a sum due hereunder to any party hereunder in one currency
into another currency, the parties hereto agree, to the fullest extent permitted
by law, that the rate of exchange used shall be that at which in accordance with
its normal banking procedures such party could purchase the first currency with
such other currency on the day which is at least two Business Days prior to the
day on which final judgment is rendered.

     (ii) To the fullest extent permitted by law, the obligation of any party in
respect of any sum payable hereunder by it to any other party hereunder shall,
notwithstanding any judgment in a currency (the "Judgment Currency") other than
Dollars (the "Agreement Currency"), be discharged only to the extent that on the
Business Day following receipt by such other party of any sum adjudged to be so
due in the Judgment Currency such other party may in accordance with normal
banking procedures purchase the Agreement Currency with the Judgment Currency;
if the amount of the Agreement Currency which could have been so purchased is
less than the sum originally due to such other party in the Agreement Currency,
such first party agrees, as a separate obligation and notwithstanding any such
judgment, to indemnify such other party against such loss, and, if the amount of
the Agreement Currency which could have been so purchased exceeds the sum
originally due to such other party, such other party agrees to remit to such
first party such excess; provided that neither any Lender nor the Administrative
Agent shall have any obligation to remit any such excess as long as the Borrower
shall have failed to pay any Lender or the Administrative Agent, as the case may
be, any obligations due and payable under this Agreement, in which case such
excess may be applied to such obligations of the Borrower hereunder in
accordance with the terms of this Agreement.

     SECTION 8.12. Waiver of Jury Trial. Each of the Borrower, the
Administrative Agent and the Lenders hereby irrevocably waive, to the extent
permitted by law, all right to trial by jury in any action, proceeding or
counterclaim (whether based on contract, tort or otherwise) arising out of or
relating to this Agreement or the Notes or the actions of any Agent or any
Lender in the negotiation, administration, performance or enforcement thereof.

     SECTION 8.13. Intercreditor Arrangements. Each of the Lenders and the
Borrower acknowledge that the Lenders hereunder, together with any Other Secured
Creditors, shall be considered to be joint creditors (credores solidarios) with
respect to the Obligations under the Loan Documents and the obligations owed to
such Other Secured Creditors; provided that if requested by the Borrower, any
Other Secured Creditors or potential Other Secured Creditors, the Lenders and
the Agents agree to negotiate in good faith with a view to agreeing to a
substitute structure governing the equal sharing of Collateral under Brazilian
law and to documentation reflecting such structure.

     SECTION 8.14. Intercreditor Agreement; Amendments to Lucent Credit
Agreement. Except with the consent of the Borrower, the Lenders shall not amend
or modify Section 4.1(a) of the Intercreditor Agreement in a manner that would
add to the limitations set forth therein on the ability of the lenders party to
any Permitted Loan Agreement (as defined in the Intercreditor Agreement) to
agree to amendments to or modifications of such Permitted Loan Agreement. The
Borrower shall not enter into any amendment to or modification of the Lucent
Credit Agreement unless it shall at the same time have offered to enter into an
amendment to or modification of this Agreement on substantially the same terms.

                             MASTER SUPPLY AGREEMENT

      This Master Supply Agreement (together with the Schedules attached hereto,
the "Agreement"), effective as of November 22, 1999 (the "Effective Date"), is
entered into by and between DIVEO, INC., a Delaware corporation with offices
located at 3201 New Mexico Avenue, NW, Suite 320, Washington, D.C. 20016 (and
together with its Affiliates, "Diveo" or "Buyer"), and LUCENT TECHNOLOGIES WORLD
SERVICES, INC., a Delaware corporation with offices located at 2333 Ponce De
Leon Boulevard, Coral Gables, Florida 33134 ("Lucent" or "Seller"). The Parties
agree that the following terms and conditions shall apply to the products and
services to be provided by Lucent under this Agreement in consideration of
certain payments to be made by Diveo. Capitalized terms used in this Agreement
are defined in the "Glossary of Defined Terms" attached hereto and incorporated
herein by this reference.


1.    AGREEMENT OVERVIEW

      1.1.  General.

            (a)   This Agreement sets forth the general terms and conditions
                  under which Diveo may purchase and receive Products and
                  Services from Lucent.

            (b)   The Parties acknowledge that this Agreement does not grant to
                  Lucent an exclusive privilege to sell or otherwise provide to
                  Diveo any or all of the Products or Services of the type
                  described in this Agreement. Diveo may contract with other
                  manufacturers and suppliers for the procurement of comparable
                  equipment, software, systems, deliverables or services. Lucent
                  is not restricted from selling the types of products or
                  services that may be purchased and ordered by Diveo hereunder
                  to other parties, except as provided in Section 8.2 with
                  respect to Developed Deliverables.

            (c)   Promptly following the Effective Date, Diveo shall cause its
                  Affiliates in the Territory to execute supplemental signature
                  pages to this Agreement in order to permit such Affiliates to
                  purchase Products and Services under this Agreement. Likewise,
                  Lucent shall, promptly following the Effective Date, cause its
                  Affiliates in the Territory to execute supplemental signature
                  pages to this Agreement to obligate such Affiliates to the
                  terms and conditions of this Agreement. Diveo and Lucent each
                  agree to guarantee the performance of their respective
                  Affiliates under this Agreement.

      1.2.  Territory.

            (a)   The Parties agree that as of the Effective Date the terms of
                  this Agreement shall apply with respect to Lucent's provision
                  of Products and Services within the Territory to Diveo and
                  Diveo's Affiliates.

            (b)   The Territory shall be expanded in the event that (i) the
                  Parties mutually agree to add a country to the list of those
                  countries comprising the Territory, in which case, the Parties
                  shall amend Schedule D to list such country or (ii) Lucent or
                  its Affiliates are directly selling in the normal course of
                  business in other countries in Latin America similar type
                  products and services as those that Diveo can

- --------------------------------------------------------------------------------

<PAGE>

                  purchase hereunder, in which case, Schedule D shall be deemed
                  to be amended to include such additional countries.

      1.3.  Strategic Relationship.

            (a)   Lucent-provided Roof Rights and Building Access. If requested
                  by Diveo, Lucent shall grant to Diveo, at no cost to either
                  Party, roof and interior rights to buildings in the Territory
                  owned by Lucent. In addition, Lucent shall, at no out of
                  pocket cost from Lucent to a third party, reasonably assist
                  Diveo in obtaining such rights with respect to any other
                  buildings leased or occupied by Lucent in the Territory.
                  Nothing herein shall obligate Lucent to violate any of its
                  existing real property lease agreements or any other agreement
                  or legal instrument to which Lucent is subject. Within ninety
                  (90) days of the Effective Date and semi-annually thereafter
                  upon Diveo's written request, Lucent shall provide Diveo with
                  a written list of all addresses of current real estate
                  properties owned or leased by Lucent in the Territory.

            (b)   Business Development. The Parties will provide reasonable
                  marketing support to each other in connection with business
                  opportunities of each Party. Such support may also include
                  co-marketing activities where Lucent would also sell Diveo
                  services and products in conjunction with Lucent services and
                  products.

            (c)   Network Element Recommendations. From time to time during the
                  Term of this Agreement, Lucent may provide, under a Purchase
                  Order Project Engineering and Professional Services (as
                  referred to in Schedule A). In the Event Diveo engages Lucent
                  to provide such Project Engineering and Professional Services
                  pursuant to an accepted Purchase Order, Lucent agrees to
                  consider what is in the best interests of Diveo in making
                  product and services recommendations, including recommending
                  Third Party Products and services where appropriate, even
                  where Lucent has competing products and services.

2.    TERM

      2.1.  Initial Term.

            The term of this Agreement shall begin upon the Effective Date and
            shall continue for a period of five years (the "Initial Term"),
            unless terminated earlier or extended in accordance with this
            Agreement.

      2.2.  Extension.

            This Agreement shall be extended for additional one year periods on
            the terms then in effect (each, an "Extended Term" and together with
            the Initial Term, the "Term") unless (i) a Party gives the other
            Party written notice sixty (60) days prior to the expiration of the
            Initial Term or Extended Term or (ii) the Agreement is otherwise
            terminated earlier in accordance with the terms of this Agreement.

            (a)   All purchases of Products or Services shall be made by means
                  of orders (each, a "Purchase Order", such term to include any
                  changes made to the Purchase Order pursuant to the terms of
                  this Agreement, including the Change Order process set forth
                  in Schedule J) issued and executed by Diveo or any of Diveo's
                  Affiliates to Lucent (or Lucent's applicable Affiliate, in the
                  case of Services to be performed in one of the countries
                  forming part of the Territory) from time to time pursuant to
                  this Section and Schedule J. Diveo will not be liable to
                  Lucent for any charges, additional or otherwise, for Products
                  or Services provided by Lucent unless set forth in a Purchase
                  Order, or otherwise mutually agreed upon by the Parties in
                  writing.

            (b)   Lucent agrees to provide and deliver, and Diveo agrees to
                  purchase according to the terms of this Agreement, including
                  the Purchase Order and Change Order Process and lead times set
                  forth in Schedule J:

                  (i)   Any Product or Service listed in a Schedule hereto that
                        is specified by Diveo in a Purchase Order that conforms
                        to Subsection (f) of this Section; and

                  (ii)  Any other Product or Service specified by Diveo in a
                        Purchase Order that conforms to Subsection (f) of this
                        Section and is accepted or is deemed to be accepted by
                        Lucent in accordance with Subsection (d) below.

            (c)   Schedule J contains Purchase Order processes that the Parties
                  will utilize in connection with the issuance of Purchase
                  Orders. Part of this process includes Purchase Order
                  Initiation Forms (POIFs).

                  (i)   Within five (5) Business Days after Lucent's receipt of
                        a POIF, which Diveo may present in connection with the
                        potential supply of Third Party Content to be provided
                        on a cost plus basis or other Products and Services
                        (including those to be provided by Lucent) for which no
                        price is specified in Schedule C, Lucent shall
                        acknowledge its receipt of such POIF and shall provide
                        Diveo with its preliminary feedback regarding the
                        subject matter thereof.

                  (ii)  As soon as practicable, but in any event within fifteen
                        (15) business days after Lucent's receipt of the POIF,
                        Lucent shall, to the extent applicable, identify for
                        Diveo's approval: (1) the proposed third party
                        suppliers, (2) their associated price quotations, (3)
                        any other proposed terms relating to the purchase of
                        such Products or Services from such third parties, and,
                        (4) in the case of Products or Services to be provided
                        by Lucent, the proposed Lucent price (subject to and in
                        accordance with the pricing set forth in this
                        Agreement).

<PAGE>

                  (iii) If Lucent fails to comply with its obligations as
                        specified in this Subsection (c), but Diveo nevertheless
                        proceeds to order the related Third Party Content
                        through Lucent, Lucent shall only be entitled to an 8%
                        markup on such Third Party Content (i.e., Lucent shall
                        not be eligible for the full 20% markup that it
                        otherwise might have been able to earn with respect to
                        such purchase as provided in Schedule C); provided that
                        nothing in this provision shall be deemed to limit
                        Lucent's otherwise applicable obligations with respect
                        to such Third Party Content.

            (d)   To the extent that any Purchase Order is either consistent
                  with (i) the requirements of a City Plan approved by Lucent or
                  (ii) Lucent's ordering lead times set forth in Schedule J for
                  the Products and Services identified therein, then Lucent may
                  not reject such Purchase Order and shall be deemed to have
                  accepted a Purchase Order on the first business day
                  immediately following receipt of such Purchase Order.
                  Otherwise, Lucent shall be deemed to have accepted a Purchase
                  Order by close of business of the tenth (10th) business day
                  following receipt of such Purchase Order if Lucent has not
                  notified Diveo in writing of its rejection of the Purchase
                  Order pursuant to Section 19.3 prior to such time. In the
                  event of a disaster declared by Diveo, Lucent will use
                  commercially reasonable efforts to expedite the acceptance of
                  any Purchase Orders that are submitted by Diveo as a means of
                  mitigating the adverse effects to Diveo of such disaster;
                  provided, however, that the terms and conditions of Section
                  3.3(c) shall not apply to such Purchase Order.

            (e)   Estimates or forecasts furnished by Diveo to Lucent shall not
                  constitute Purchase Orders or commitments for purchases.

            (f)   Purchase Orders placed under this Agreement may be made by
                  means of mail or fax pursuant to Section 19.3, Diveo's
                  extranet ordering system, or such other mutually agreed upon
                  methods (e.g., electronic data interchange). No Purchase Order
                  or other ordering document which would otherwise modify or
                  supplement this Agreement or any Schedule shall add to or vary
                  the terms of this Agreement. All such proposed variations or
                  additions (whether submitted by either Party) are hereby
                  objected to and deemed material. Each Purchase Order shall
                  contain the applicable information set forth in Schedule J.

      3.2.  Administrative Changes.

            Lucent will use commercially reasonable efforts to notify Diveo at
            least thirty (30) calendar days in advance of any administrative
            changes with respect to any Product set forth in Schedule A or
            previously provided by Lucent to Diveo, such as changes in product
            part numbers or descriptions, as well as newly compatible products
            or components.

      3.3.  Timing of Delivery.

            (a)   The Delivery and Acceptance dates for Products and Delivery
                  for Services shall be firm. Lucent will deliver Products and
                  Services strictly in accordance with

- --------------------------------------------------------------------------------
Master Supply Agreement                 4            Diveo / Lucent Confidential
<PAGE>

                  the terms and conditions of accepted or deemed accepted
                  Purchase Orders or Change Control Form (as such Change Control
                  Form is further described in Schedule J).

            (b)   If Lucent discovers any potential delay that threatens the
                  timely Delivery and Acceptance of Products or the Delivery of
                  Services with respect to a Purchase Order, Lucent shall
                  immediately notify Diveo of such delay. If requested by Diveo,
                  Lucent shall provide a written plan for correction of such
                  delay.

            (c)   Subject to Sections 3.1(d), 9.2 and 15.3, if Lucent fails to
                  deliver

                  (i)   any Product or Service for which a corresponding
                        Delivery time is set forth in Schedule J of the
                        Agreement in accordance with such corresponding Delivery
                        time;

                  (ii)  any other Products or Services in accordance with the
                        scheduled Delivery date or Acceptance date set forth in
                        the corresponding accepted Purchase Order;

                  then after five (5) business days following such scheduled
                  Delivery or Acceptance date, as applicable, Diveo shall be
                  entitled to deduct from the price of the Products, Services or
                  both (if included in the Purchase Order) an amount equal to
                  one-tenth of a percent (.1%) of the price of Products and
                  Services under such Purchase Order for each calendar day of
                  delay after such five-day grace period until actual Delivery
                  or Acceptance (or Provisional Acceptance), as applicable, of
                  such Products and Services, up to a maximum deduction of one
                  hundred percent (100%) of the price for such Products and
                  Services (the "Delivery Pricing Adjustment"). Notwithstanding
                  the preceding sentence, Lucent shall not be liable for a
                  Delivery Pricing Adjustment to the extent that Lucent can
                  demonstrate that its failure to deliver a Product or Service
                  in accordance with the scheduled Delivery or Acceptance date,
                  as applicable, set forth in the corresponding Purchase Order
                  is reasonably caused by (i) the wrongful actions of Diveo, or
                  (ii) a force majeure condition as defined in this Agreement,
                  or (iii) a change, revision, modification, or special
                  requirement with respect to such Product, or Service, or the
                  Delivery date for such Product or Service, each to the extent
                  requested by Diveo and approved by Lucent after Lucent has
                  accepted the Purchase Order corresponding to such Product or
                  Service. To the extent that Diveo has not otherwise terminated
                  the Purchase Order as provided in Subsection 3.5 below and
                  Diveo has elected to take the Delivery Pricing Adjustment as
                  provided above, such adjustment shall be Diveo's sole and
                  exclusive monetary remedy with respect to the delay
                  attributable to the failure to complete the Purchase Order;
                  provided, however, that in the event Lucent has persistent
                  delays over multiple Purchase Orders, such Delivery Pricing
                  Adjustment shall be in addition to any other rights or
                  remedies Diveo may have under this Agreement or at law or in
                  equity. Lucent agrees not to make an economic determination
                  not to deliver a Product or Service under a particular
                  Purchase Order due to the Delivery Pricing Adjustment.

<PAGE>

            (d)   If Lucent fails to make any Delivery or Acceptance (or
                  Provisional Acceptance) of a Product or Delivery of a Service
                  within the lesser of

                  (i)   forty-five (45) calendar days after the scheduled
                        Delivery date or Acceptance date set forth in the
                        corresponding Purchase Order, and

                  (ii)  such other time period as mutually agreed by the
                        Parties,

                  Then Diveo shall be entitled to terminate the corresponding
                  Purchase Order in accordance with Section 3.5.

            (e)   Lucent agrees to use its commercially reasonable efforts to
                  have scheduled shipment dates for Purchase Orders to be as
                  close to the Delivery date as possible.

      3.4.  Cancellation and Rescheduling of Purchase Orders

            (a)   Diveo can cancel Purchase Orders with respect to Products
                  contained in such Purchase Orders, in whole or in part at no
                  cost or liability anytime up to forty-five (45) days prior to
                  the scheduled shipment date for such Product. Should Diveo
                  cancel any Purchase Order for Products, in whole or in part
                  other than pursuant to Section 3.5, during the forty-five (45)
                  day period prior to the scheduled shipment date, Diveo agrees
                  to pay to Lucent cancellation and reconfiguration charges
                  equal to:

                  (i)   five percent (5%) of the value of the canceled portion
                        of the Purchase Order if the cancellation notice is
                        given between twenty (20) and forty-five (45) days prior
                        to the scheduled shipment date; or

                  (ii)  twenty percent (20%) of the value of the canceled
                        portion of the Purchase Order if the cancellation notice
                        is given within twenty (20) days prior to the scheduled
                        shipment date.

            (b)   Diveo can cancel Purchase Orders with respect to Services
                  contained in such Purchase Orders, in whole or in part, at no
                  cost or liability anytime prior up to twenty (20) days prior
                  to the scheduled start date set forth in the Purchase Order.
                  Should Diveo cancel any Purchase Order for Services, in whole
                  or in part other than pursuant to Section 3.5, during the
                  twenty (20) day period prior to the scheduled start date,
                  Diveo agrees to pay to Lucent cancellation charges for which
                  Diveo has been given prior notice on an Out-of-Pocket Expenses
                  basis equal to Lucent's demonstrable cancellation fees payable
                  to a third party, if any, as a direct result of such Diveo
                  cancellation..

            (c)   Purchase Orders for Products only may not be canceled
                  following shipment of the Products. Purchase Orders for
                  Services only may not be canceled following start of the
                  Service. The foregoing shall not impact any rights or remedies
                  otherwise available to Diveo under this Agreement.

            (d)   Following the Change Control process as specified in Schedule
                  J, Diveo may change the "ship to" destination of any Product
                  corresponding to a Purchase

- --------------------------------------------------------------------------------
Master Supply Agreement                 6            Diveo / Lucent Confidential
<PAGE>

                  Order by submitting notice to Lucent in writing at least ten
                  (10) calendar days prior to delivery of the Product(s) at the
                  designated site. If such change is requested by Diveo with
                  less than forty-eight hours of notice prior to shipment,
                  Lucent will use all reasonable efforts to implement such
                  change. Diveo will be responsible for all additional
                  Out-of-Pocket Expenses that Lucent reasonably incurs as a
                  direct result of such change. Lucent will provide Diveo with
                  an estimate of such Out-of-Pocket Expenses as soon as possible
                  following Diveo's notice.

            (e)   Diveo may, without cost to Diveo, reschedule Delivery of any
                  Product corresponding to any Purchase Order at anytime prior
                  to actual shipment such that the resulting rescheduled
                  shipping date is up to one hundred twenty (120) days from the
                  original scheduled shipment date specified in the Purchase
                  Order (or such later date as either mutually agreed upon by
                  the Parties or identified as the ship date by Lucent);
                  provided, however, that unless otherwise agreed upon by the
                  Parties, Diveo may not reschedule any Product if the Delivery
                  of such Product was previously rescheduled by Diveo pursuant
                  to this Subsection (e). Such rescheduling shall be at no
                  liability to Diveo. Provided that the rescheduling was not
                  caused by delays by Lucent, Diveo shall be responsible solely
                  for additional Out-of-Pocket Expenses actually incurred by
                  Lucent for third party storage and transportation, if any.

            (f)   Diveo may reschedule Delivery of any Service corresponding to
                  any Purchase Order at anytime prior to scheduled start date
                  such that the resulting rescheduled delivery date is up to one
                  hundred twenty (120) days from the original start date
                  specified in the Purchase Order (or such later date as either
                  mutually agreed upon by the Parties). Such rescheduling shall
                  be at no cost or liability to Diveo.

            (g)   For the limited purpose of Diveo exercising its rights to
                  cancel or reschedule Delivery of Purchase Orders pursuant to
                  this Section only, all references in this Section 3.4 to the
                  scheduled shipment date specified in the Purchase Order shall
                  be extended day-for-day by the number of days Lucent is
                  delayed or is reasonably expected to be delayed in meeting the
                  scheduled shipment date.

      3.5.  Termination of Purchase Orders.

            (a)   As provided in Sections 3.3(d) and 6.2, Diveo may, by giving
                  written notice to Lucent, terminate the applicable Purchase
                  Order, in whole or in part, for cause as of a date specified
                  in the notice of termination. Additionally, in the event that
                  a Product fails to comply with the applicable Acceptance
                  Criteria as set forth in the Agreement, then Diveo may, by
                  giving written notice to Lucent, terminate, in whole or in
                  part for cause as of a date specified in the notice of
                  termination, any Purchase Orders under which Diveo has ordered
                  a quantity of the same Product or related Services and Lucent
                  has not yet Delivered such Products or related Services.

            (b)   In either of such events as described in Subsection (a), Diveo
                  may return to Lucent, those Products forming part of the same
                  Purchase Order that were delivered by Lucent during the sixty
                  (60) days immediately preceding the

- --------------------------------------------------------------------------------
Master Supply Agreement                 7            Diveo / Lucent Confidential
<PAGE>

                  termination of the Purchase Order and that were intended to be
                  integrated and/or installed by Lucent with the foregoing
                  Products subject of the events described in Subsection (a), in
                  which case Lucent shall promptly refund to Diveo all charges
                  paid by Diveo to Lucent for such Products, and Diveo shall
                  have no further payment obligations to Lucent with respect to
                  such Products. The foregoing refund will be in the form of a
                  credit and payable by Lucent to Diveo in accordance with
                  Section 11.1(c).

      3.6.  Demonstration Products.

            From time to time and at Diveo's reasonable request and at Lucent's
            discretion, Lucent may, at no charge, provide Diveo with limited
            quantities of Lucent Products not previously introduced to the
            market generally by Lucent for the purpose of Diveo's evaluation (or
            demonstration) for a trial period. Such trial shall be conducted
            upon written terms and conditions mutually acceptable to the
            Parties.

4.    SHIPPING AND DELIVERY

      4.1.  Incorrect Delivery.

            (a)   Early deliveries of Products may be refused due to space or
                  security considerations and returned or stored at Lucent's
                  expense and risk of loss.

            (b)   Diveo assumes no liability for Services rendered or Products
                  produced, processed, rendered or shipped in excess of the
                  amounts specified in any Purchase Order submitted pursuant to
                  this Agreement.

            (c)   If Lucent makes a proper shipment in a timely manner and the
                  Diveo facility is not prepared to receive the shipment, Diveo
                  will be responsible for unavoidable Out-of-Pocket Expenses
                  that Lucent reasonably incurs as a direct result of Diveo's
                  failure to prepare. Lucent will provide Diveo with an estimate
                  of such Out-of-Pocket Expenses as soon as possible following
                  Diveo's notice.

      4.2.  Purchase Order Tracking.

            In accordance with Schedule J, Lucent shall be responsible for
            tracking and reporting on the Delivery and Acceptance (if
            installation Services are being provided) of all Products from
            receipt of the corresponding Purchase Order until Delivery or
            Acceptance, as applicable, of such Products to the Diveo-designated
            place of Delivery or Acceptance. Lucent will provide Diveo with
            current status reports and information on Purchase Orders on a
            monthly basis or more often as requested by Diveo and such other
            information and reports as reasonably requested by Diveo regarding
            Purchase Orders.

      4.3.  Packing.

            All Products delivered to Diveo pursuant to this Agreement shall be
            preserved, packaged and packed by Lucent to ensure safe Delivery to
            their destinations without damages due to shipment.

<PAGE>

      4.4.  Labeling.

            (a)   Lucent will label each component of any Lucent Product no
                  later than at the time of Delivery of such components (or upon
                  installation if Lucent is to provide installation Services in
                  connection with such components). In addition to the
                  foregoing, Lucent will use reasonable and good faith efforts
                  to label each component of any Lucent Product, each container
                  and each set of packing documentation with any Diveo-provided
                  asset identification information prior to the Delivery or
                  installation of such components. Lucent shall follow industry
                  practices in labeling Products.

            (b)   Lucent will mark each shipping carton with (i) a brief
                  description of the contents and quantities of the Products
                  shipped within such shipping carton, and (ii) the address of
                  the Delivery destination specified on the applicable Purchase
                  Order.

      4.5.  Factory Testing.

            The Lucent Products shall be tested by Lucent in accordance with
            Lucent's relevant standard factory testing procedures. Diveo shall
            have the right, but not the obligation, to be present during the
            performance of such factory tests. If requested by Diveo, Lucent
            agrees to provide results of the tests for such Lucent Products
            purchased by Diveo hereunder, consistent with Lucent's applicable
            policies.

      4.6.  Shipping

            (a)   Lucent will notify Diveo of Lucent's intent to ship Products
                  within a reasonable time prior to the scheduled Delivery date
                  as specified in the Purchase Order at the Delivery destination
                  address specified in a Purchase Order, so as to permit Diveo
                  to make necessary arrangements for receipt of the shipment.
                  The foregoing notwithstanding, Lucent shall deliver such
                  Products consistent with the agreed upon City Plan and
                  otherwise in accordance with the Agreement.

            (b)   Lucent will ship all Products to the Delivery destination
                  specified by Diveo in the corresponding Purchase Order in
                  accordance with applicable laws and regulations. All shipments
                  to Diveo's premises shall be consistent with Diveo's
                  reasonable shipping and delivery processes and procedures
                  provided or identified to Lucent in writing. Lucent will (i)
                  ship all deliveries complete unless otherwise agreed by Diveo,
                  and (ii) not ship any substitute item in place of a Product
                  specified in a Purchase Order that differs in form, fit or
                  function, unless otherwise agreed by Diveo in writing.

            (c)   Unless otherwise instructed by Diveo, Lucent will:

                  (i)   enclose a packing memorandum with each shipment and,
                        when more than one package is shipped, identify the one
                        which contains the memorandum;

                  (ii)  verify that bills of lading match corresponding shipping
                        invoices; and

- --------------------------------------------------------------------------------

<PAGE>

                  (iii) forward applicable bills of lading and shipping notices
                        with items shipped.

            (d)   All deliveries will be made as provided in Schedule C.

      4.7.  Title and Risk of Loss.

            (a)   Risk of loss of any Product shipped to Diveo will pass to
                  Diveo upon delivery of the Product to the designated site. In
                  the event a Product or Products are ordered with installation,
                  implementation and/or engineering Services, Lucent shall
                  continue to be responsible for all risk of loss on such
                  Product or Products (as if risk of loss did not pass upon
                  Delivery) until Acceptance of the Product or Products. In
                  connection with all of the foregoing, Lucent shall obtain all
                  necessary insurance its own name and shall be responsible for
                  any loss to the Products prior to the time periods set forth
                  above.

            (b)   License to use Software and title to Products shall pass to
                  Diveo as follows:

                  (i)   Where a Product or Software is shipped to the designated
                        site or destination specified in the Purchase Order from
                        a country that is different from the country of such
                        designated site or destination (the country of such
                        designated site or destination the "Destination
                        Country"), such title to the Product or license to use
                        such Software, as applicable, shall pass immediately
                        prior to importation in the Destination Country; or

                  (ii)  Where a Product or Software is shipped to the designated
                        site or destination specified in the Purchase Order from
                        within the same country as the country of such
                        designated site or destination, such title to the
                        Product or license to use such Software, as applicable,
                        shall pass upon delivery of such Product or Software to
                        the designated site or destination specified in the
                        Purchase Order.

5.    DELIVERY OF SERVICES

      5.1.  Use of Third Parties.

            (a)   Lucent shall notify Diveo in writing in advance of engaging
                  any subcontractor to perform any of the obligations of Lucent
                  hereunder. Diveo shall have five (5) business days (or two (2)
                  business days in the event of an emergency) from receipt of
                  such notification to approve or disapprove the named
                  subcontractor in writing, provided that any disapproval of a
                  subcontractor is reasonably based. In the event that Diveo
                  fails to disapprove a subcontractor within the aforesaid
                  period, Diveo shall be deemed to have approved the said
                  subcontractor.

            (b)   Lucent will remain solely responsible for all obligations
                  performed by its subcontractors to the same extent as if such
                  obligations were performed by Lucent itself. Lucent shall be
                  Diveo's sole point of contact regarding Products and Services
                  provided by such subcontractors, including with respect to
                  payment. Lucent will not disclose Confidential Information of
                  Diveo to a

- --------------------------------------------------------------------------------
Master Supply Agreement                10            Diveo / Lucent Confidential
<PAGE>

                  subcontractor unless and until such subcontractor has agreed
                  in writing to protect the confidentiality of such information
                  in a manner substantially equivalent to that required of
                  Lucent under this Agreement, and in all respects, only on a
                  "need-to-know" basis.

            (c)   Upon Diveo's request, Lucent shall provide program management
                  with respect to Diveo's personnel and third party service
                  providers contracted directly by Diveo to perform services
                  related to the Products and Services. Subject to the terms of
                  this Agreement, Diveo retains the option (at its sole
                  discretion) to utilize their direct, indirect or contracted
                  personnel to perform services under this Agreement. In the
                  event Lucent intends to subcontract a particular component of
                  the Services to a third party, Lucent shall notify Diveo and
                  Diveo shall have the option (which option shall be exercised
                  within a reasonable time), in its sole discretion, to perform
                  such services itself or through its own subcontractor. Such
                  Diveo personnel and third parties shall not be considered
                  Lucent subcontractors for the purposes of this Agreement and
                  Lucent shall not be liable for the performance of such
                  services under this Agreement.

      5.2.  Key Lucent Positions and Management Escalation Process.

            (a)   Lucent shall assign individuals reasonably acceptable to Diveo
                  to fill the "Key Lucent Positions" set forth as such in
                  Schedule I, as Schedule I is amended from time to time by the
                  mutual written agreement of the Parties.

            (b)   In accordance with Section 17.1, issues arising between the
                  Parties may be escalated in accordance with management
                  escalation procedures set forth in Schedule I.

            (c)   Lucent agrees to use reasonable efforts to minimize any
                  turn-over or reassignment of the personnel filling the Key
                  Lucent Positions. Lucent agrees that personnel filling Key
                  Lucent Positions may not be transferred or re-assigned until a
                  suitable replacement has been put into place and the functions
                  and responsibilities of the individual being transferred or
                  re-assigned have been properly transitioned to the
                  replacement. Lucent agrees to consult with Diveo in connection
                  with the transfer or re-assignment of any personnel in the Key
                  Lucent Positions.

            (d)   As further provided in Schedule I, upon commencement of each
                  project (i.e., installation, implementation and/or engineering
                  Services), and until such time as the implementation for such
                  project is complete, Lucent shall appoint and maintain a
                  project manager, reasonably acceptable to Diveo, to devote the
                  necessary time and effort to the provision of the Services
                  required to fulfill the implementation of such project. Diveo
                  shall likewise appoint a project manager for each project.
                  Each Party's project manager shall be familiar with the
                  project and shall have authority to make day-to-day and
                  emergency decisions on behalf of such Party during the
                  implementation of the project.

<PAGE>

      5.3.  Implementation Plans, Milestones and Milestone Dates.

            For all projects (e.g., installation, implementation and/or
            engineering Services) that result in the installation,
            implementation and/or engineering of of Product(s):

            (a)   Lucent shall prepare for Diveo's review, comment and approval,
                  a detailed, task-level implementation plan delineating
                  milestones (each, a "Milestone"), Milestone completion dates
                  (each, a "Milestone Date"), together with each Party's
                  respective responsibilities associated with the installation
                  or implementation work.

            (b)   If Lucent fails to achieve a Milestone on or before the
                  corresponding Milestone Date, (i) Lucent's Country Project
                  Manager (or in the event such position no longer exists, an
                  executive with a similar level of responsibility) will meet
                  with Diveo in person at Diveo's facilities, explain to Diveo
                  the root cause for the delay, and present to Diveo a plan to
                  remedy such failure, (ii) Lucent will take appropriate
                  preventive measures so that the failure does not recur, and
                  reasonably demonstrate to Diveo that such measures have been
                  performed.

6.    ACCEPTANCE TESTING AND FINAL ACCEPTANCE

      6.1.  Acceptance Testing.

            (a)   Schedule F (Acceptance Test Plans) describes the three levels
                  of testing for the Products (i.e., unit testing, network
                  element testing and system testing) and such testing will be
                  implemented in accordance with Schedule F.

            (b)   In the event Lucent is providing Services that includes
                  Acceptance testing of Products, Lucent shall perform the
                  testing (for Diveo's review and Acceptance) in accordance with
                  Schedule F and the applicable Acceptance Test Period.
                  Alternatively, if Diveo is performing the Acceptance testing
                  without the assistance of Lucent, Acceptance testing of the
                  Products shall be conducted by Diveo within the applicable
                  Acceptance Test Period.

            (c)   In either case as set forth in (b) above, if such Product(s)
                  meets its Acceptance Criteria, Diveo will notify Lucent in
                  writing that such Product has received Acceptance pursuant to
                  Section 6.3. If such Product(s) does not meet its Acceptance
                  Criteria, Diveo may notify Lucent in writing of the failures
                  of the Product(s) to meet its Acceptance Criteria and Lucent
                  shall correct such problems in accordance with Section 6.2;
                  provided, however, if Lucent is providing Services that
                  includes Acceptance testing, Diveo shall not be obligated to
                  provide such notice of failures until such time following
                  Lucent's notice to Diveo that the Products have passed the
                  applicable Acceptance Criteria (i.e., Lucent Certification)
                  and are available for verification by Diveo in accordance with
                  Schedule F. Alternatively, Diveo may accept such Product
                  pursuant to Section 6.3 upon the condition that such failures
                  will be corrected by Lucent within a period of time reasonably
                  specified by Diveo (such acceptance a "Provisional
                  Acceptance"). In the event Diveo or its Affiliates, as
                  applicable, places a Product into commercial, revenue
                  producing service, such Product shall


- --------------------------------------------------------------------------------
Master Supply Agreement                12            Diveo / Lucent Confidential
<PAGE>

                  be considered Provisionally Accepted; provided that final
                  Acceptance of such Product shall be based upon the condition
                  that all other Products subject of the Purchase Order that are
                  required to be installed together and integrated as a complete
                  system also pass Acceptance.

      6.2.  Acceptance Testing Failures, Cure Periods and Remedies.

            (a)   If any Product(s) subject to Acceptance testing as described
                  in Section 6.1 fails to pass Acceptance testing, Diveo will
                  promptly (and in no event later than the applicable Acceptance
                  Testing Period) notify Lucent in writing, specifying the
                  nature of the failure in reasonable detail. Within ten (10)
                  days after receiving notice from Diveo, Lucent shall either
                  (i) correct all problems identified by Diveo, or, if that is
                  not reasonably possible, (ii) develop a plan for Diveo's
                  acceptance that describes in reasonable detail the steps
                  Lucent intends to take to correct such problem(s) within
                  thirty (30) days, and diligently proceed according to the plan
                  until all of the problem(s) are corrected. Upon completion of
                  such problem corrections, Diveo shall reconduct the Acceptance
                  testing as provided in Section 6.1 to the extent that Diveo
                  deems necessary to determine the compliance of the Product
                  with the Acceptance Criteria.

            (b)   Notwithstanding Subsection (a) above, if after a reasonable
                  number of repeated efforts (but not more than three (3)
                  attempts or more than a total of sixty (60) days for curing
                  all problems encountered), Lucent is unable to correct all of
                  the problems preventing Acceptance, Diveo may at its election:

                  (i)   extend the testing periods for a reasonable period of
                        time and require Lucent to immediately replace the
                        non-conforming item(s);

                  (ii)  accept the affected items at a mutually agreed reduced
                        price that reflects the diminished functionality, to be
                        replaced by full functionality items in the future at
                        Diveo's discretion, at which time full payment will be
                        made; or

                  (iii) cancel or modify the corresponding Purchase Order and
                        any other affected Purchase Order for cause and at no
                        cost to Diveo and Lucent shall promptly refund (not to
                        exceed 30 days) any amounts paid by Diveo or its
                        Affiliates for such Purchase Orders.

      6.3.  Acceptance.

            A Product shall be considered to be accepted (the "Acceptance") only
            as follows:

            (a)   With respect to a Product or Products subject of a Purchase
                  Order without installation, implementation and/or engineering
                  Services), such Products shall be Acceptance tested within
                  five (5) business days of delivery of the Product or Products
                  to the designated site or destination named in the Purchase
                  Order. Such Acceptance testing shall include an incoming
                  inspection to verify that such Product has been delivered in
                  accordance with the corresponding Purchase Order and meets the
                  Acceptance Criteria; and


- --------------------------------------------------------------------------------
Master Supply Agreement                13            Diveo / Lucent Confidential
<PAGE>

            (b)   With respect to any other Product, such Product shall be
                  considered to be accepted upon the earliest of:

                  (i)   receipt by Lucent of written notice by Diveo certifying
                        that such Product conforms to its Acceptance Criteria;

                  (ii)  satisfaction of all conditions underlying a Provisional
                        Acceptance as described in Section 6.1, or

                  (iii) the expiration of the Acceptance Testing Period for such
                        Product without notice of non-acceptance or of the terms
                        of a Provisional Acceptance by Diveo.

                  Notwithstanding anything to the contrary herein, Acceptance of
                  a Product shall only occur in accordance with the terms of
                  this Agreement.

7.    SERVICE LEVELS

      7.1.  General.

            Lucent shall at all times meet or exceed the quantitative and
            qualitative service levels identified in Schedule B (the "Service
            Levels").

      7.2.  Failure to Perform.

            (a)   Lucent recognizes that its failure to meet Service Levels as
                  specified in Schedule B, may have a material adverse impact on
                  the business and operations of Diveo. Accordingly, in the
                  event that Lucent fails to meet such Service Levels for
                  reasons other than the wrongful actions of Diveo (including
                  Diveo's failure to perform its duties and obligations on a
                  timely basis) or circumstances that constitute force majeure
                  under this Agreement, Diveo may elect, in addition to any
                  other rights or remedies available to Diveo hereunder, to
                  pursue remedies according to Schedule B.

            (b)   If Lucent fails to meet any Service Level, Lucent shall (i)
                  investigate and report on the root causes of the problem; (ii)
                  advise Diveo, as and to the extent requested by Diveo, of the
                  status of remedial efforts being undertaken with respect to
                  such problems; (iii) correct the problem and begin meeting the
                  Service Levels in the case that the root causes of the problem
                  are within Lucent's control; and (iv) take appropriate
                  preventive measures so that the problem does not recur.

      7.3.  Periodic Reviews.

            Within three (3) months after the expiration of the first year
            following the Effective Date and at least annually thereafter, Diveo
            and Lucent shall review the Service Levels and shall make
            adjustments to them as appropriate to reflect improved performance
            capabilities associated with advances in the technology and methods
            used to provide the Products and perform the Services.

      7.4.  Measurement and Monitoring Tools.


            Lucent shall use the measurement and monitoring tools and procedures
            required to measure and report Lucent's performance of the Services
            against the applicable Service Levels. Lucent shall report on all
            Service Levels each month during the Term. Such measurement and
            monitoring will permit reporting at a level of detail sufficient to
            verify compliance with the Service Levels and will be subject to
            audit by Diveo. Lucent shall provide Diveo with information and
            access to such tools and procedures upon request, for purposes of
            verification.

8.   SOFTWARE LICENSES AND PROPRIETARY RIGHTS

      8.1.  Licenses.

            (a)   Commencing upon Delivery of Software pursuant to this
                  Agreement, Lucent grants Diveo and its Affiliates a perpetual,
                  transferable (as provided herein), nonexclusive, fully-paid,
                  royalty-free, irrevocable (except as provided by Subsection
                  (b) of this Section) and world-wide right and license (or
                  sublicense in the case of Software owned by a third party) to
                  use, copy (as provided herein), access, display, operate and
                  process the Software provided to Diveo pursuant to a Purchase
                  Order (collectively, the "Licenses"). These rights may be
                  exercised through officers, employees and agents for the sole
                  purpose of providing services to Diveo and its Affiliates.
                  Diveo may copy the Software for back-up purposes and for uses
                  that are in accordance with this Agreement. Any such
                  reproduction will include any copyright or similar proprietary
                  notice contained in the Software being reproduced. Diveo may
                  not decompile, disassemble or reverse engineer the Software.

            (b)   Lucent may revoke a particular License if and only if Diveo
                  (i) fails to pay undisputed licensing fees associated with
                  such License, and such nonpayment is not cured within thirty
                  (30) calendar days after written notice of such nonpayment
                  provided by Lucent to Diveo or (ii) fails to use commercially
                  reasonable efforts to cease from decompiling, disassembling or
                  reverse engineering the Software following receipt of notice
                  from Lucent.

            (c)   To the extent that Lucent is unable to secure the rights
                  specified in Section 8.1 with respect to Software associated
                  with Third Party Products, it shall be excused from that
                  obligation, provided that it gives Diveo prior written notice
                  of such inability sufficiently in advance so that Diveo may
                  seek alternate means of obtaining such rights.

            (d)   Diveo may, at no charge, relocate any Software to another
                  location for reuse with Equipment with which it was originally
                  delivered when such Equipment is itself to be relocated
                  consistent with this Agreement. Such relocation or reuse shall
                  not alter the Licenses.

            (e)   Diveo shall have the right to transfer any of the Licenses in
                  the event Diveo sells the Equipment with which such Software
                  is utilized or any component thereof in accordance with
                  Section 8.3, or in the event of an assignment or change in


- --------------------------------------------------------------------------------
Master Supply Agreement                15            Diveo / Lucent Confidential
<PAGE>

                  control in accordance with Section 19.1. Such transfers shall
                  be subject to (i) the transferee undertaking the restrictions
                  and covenants of the license, (ii) reasonable creditworthiness
                  of the transferee, (iii) a limitation that the transferee is
                  not a direct competitor of Lucent in the area of
                  telecommunications equipment manufacture, and (iv) with
                  respect to Software that is embedded as part of Equipment, a
                  limitation that the Software may be used only with the
                  Equipment on which it was utilized prior to the transfer.

            (f)   Lucent agrees to furnish and convey, at no additional charge
                  to Diveo, such documentation, training materials, manuals,
                  appropriate designs, appropriate drawings, and other media and
                  material pertaining to the use and operation of Products as is
                  necessary to permit Diveo to use and maintain such items in
                  accordance with this Agreement (the "Documentation"). Lucent
                  will provide the Documentation in both hard- and soft-copy
                  formats. Diveo may make a reasonable number of copies of the
                  Documentation; provided, however, that all such copies shall
                  contain the copyright legends placed on the original versions
                  by Lucent.

            (g)   In the event that a Diveo employee violates the License
                  restrictions set forth in Subsection (a) of this Section,
                  Diveo shall, at its own expense take such reasonable actions
                  as may be necessary to remedy such violation and cooperate in
                  all reasonable respects to minimize the violation and any
                  damage resulting therefrom.

            (h)   Except as otherwise provided pursuant to Section 8.4, no
                  Source Code is included in Software provided under the
                  Agreement. Diveo acknowledges that, in the event it attempts
                  to decompile, disassemble or reverse engineer Software other
                  than any Developed Deliverable, Lucent may proceed directly to
                  court. If a court of competent jurisdiction should find that
                  Diveo has attempted to decompile, disassemble or reverse
                  engineer such Software, Diveo agrees that without any
                  additional findings of irreparable injury or other conditions
                  to injunctive relief, Lucent shall be entitled to seek the
                  entry of an appropriate order against Diveo without opposition
                  to restrain Diveo from any further attempt to decompile,
                  disassemble or reverse engineer such Software.

      8.2.  Proprietary Rights.

            (a)   Title to the Software shall remain in Lucent or its suppliers.
                  Title to any software owned or licensed directly by Diveo
                  (other than Software licensed from or through Lucent under
                  this Agreement) shall not be affected by this Agreement and
                  such title shall remain with Diveo or its suppliers. With
                  respect to any documentation, engineering, designs or other
                  requested Services that result in a documentation deliverable,
                  Diveo may use such deliverable in any manner and to the extent
                  such deliverable incorporates or is based on Diveo provided
                  technical information or specifications Lucent agrees not to
                  use such information or specifications in connection with any
                  other similar work for any other customer of Lucent.

<PAGE>

            (b)   The Parties do not expect that Lucent will develop custom
                  Software in the course of performance under this Agreement,
                  and nothing contained in the Agreement may be interpreted to
                  require Lucent to develop such custom Software.

            (c)   Diveo and Lucent may agree that Lucent will perform certain
                  custom development work pursuant to mutually agreed-upon
                  terms, conditions and fees set forth in a separate written
                  agreement duly signed by the Parties (such Deliverables the
                  "Developed Deliverables").

      8.3.  Right to Resell and Sublicense.

            Except as may be otherwise provided by the terms and conditions of
            the Credit Agreement, Diveo shall have the right to assign,
            transfer, sell, alienate or lease Lucent Products, and, subject to
            Section 8.1, sublicense the right to use the Software that is
            embedded or otherwise provided with such Lucent Products to third
            parties in conjunction with (A) the disposal of such Products,
            provided that (i) Diveo shall not sell or otherwise transfer a
            Lucent Product to any person or entity that is a manufacturer of
            telecommunications products that compete directly with the Lucent
            Products being disposed of, and (ii) all warranties applicable to
            such Product shall automatically terminate at the time Diveo makes
            delivery of the Product to the third party, and (B) (i) Customer
            Colocations involving such Products, or (ii) Customer Virtual
            Colocations involving such Products, and pass through to such
            customers the standard warranty rights (and the applicable warranty
            exclusions) granted by Lucent generally to its customers, which
            rights shall be valid only for the remaining term, if any, of the
            Initial Warranty Period applicable to such Products; provided,
            however, if this Agreement is assigned as provided herein, the
            rights granted to Diveo under this Agreement that are applicable to
            such Lucent Products shall be assignable to the assignee of this
            Agreement. In connection therewith:

            (a)   Each third party shall agree in writing that its license for
                  any Software to which Lucent maintains title under this
                  Agreement is revocable by Lucent in the event such third party
                  materially breaches the licensing restrictions imposed upon
                  Diveo under this Agreement pursuant to Section 8.1;

            (b)   Each such third party shall agree in writing to
                  confidentiality terms and conditions substantially similar to
                  those set forth in Article 12; and

            (c)   With respect to rights granted to Diveo under Article 13 and
                  passed through to such third parties, the Parties will agree
                  upon a reasonable means of administering Lucent's fulfillment
                  of its obligations with respect to such rights.

            Where Diveo substantially complies with the obligations set forth
            above, Diveo shall have no liability to Lucent for any action or
            omission of such third parties except for providing Lucent
            reasonable assistance in bringing claims as against the third party
            for reasonable claims.

      8.4.  Technical Materials Availability

            (a)   As used herein, a "Technical Materials Trigger Event" shall
                  mean the satisfaction of any of the following conditions: (i)
                  the insolvency of Lucent or the institution by Lucent of
                  insolvency, receivership or bankruptcy proceedings; (ii) a
                  general assignment by Lucent for the benefit of creditors;
                  (iii) the appointment of a receiver for Lucent; or (iv) the
                  filing of creditors of Lucent of a petition in bankruptcy
                  against Lucent which is not stayed or dismissed within sixty
                  (60) calendar days together with a material breach by Lucent
                  or where there is an inability for Lucent to perform within
                  such sixty (60) days.

            (b)   Upon the occurrence of a Technical Materials Trigger Event,
                  Lucent shall immediately deliver to Diveo the Source Code for
                  Lucent Products and grant to Diveo at no additional charge a
                  license to use, copy, access, display, modify, enhance,
                  operate, process and create derivative works of the Source
                  Code for the Lucent Product(s) then being used by Diveo and
                  any associated documentation for such Lucent Products to the
                  extent necessary for Diveo to modify, maintain and enhance
                  solely for its own use in accordance with the terms of this
                  Agreement, the Lucent Products that Diveo has the right to use
                  under this Agreement; provided, however, such license and
                  delivery of the Source Code will not be required where Diveo
                  can obtain, with Lucent's assistance (e.g., by providing a
                  third party with Source Code or by any other appropriate
                  method), the same support services that Lucent is required to
                  provide under this Agreement from another entity (either
                  working with or independently from Lucent) at a price that is
                  equal to or less than prices for such support as provided
                  herein. Any such released Source Code shall be subject to the
                  confidentiality provisions set forth in this Agreement.

            (c)   Lucent acknowledges that, in the event it breaches its
                  obligation to provide the Source Code and license as provided
                  in this Section, Diveo may be irreparably harmed. In such a
                  circumstance, Diveo may proceed directly to court.

9.    DIVEO RESPONSIBILITIES

      9.1.  Facilities and Resources.

            Diveo's responsibility for providing facilities, personnel and other
            resources as necessary to permit Lucent to deliver the Products and
            Services shall be as set forth in this Agreement.

      9.2.  Savings Clause.

            (a)   Diveo's failure to perform any of its responsibilities set
                  forth in this Agreement (other than Diveo obligations to pay
                  undisputed amounts under Article 10.3) shall not constitute a
                  material breach of the Agreement or otherwise be deemed to be
                  grounds for termination by Lucent.

            (b)   Each Party's nonperformance of its obligations under this
                  Agreement shall be excused (such Party the "Excused Party") if
                  and to the extent: (i) such

- --------------------------------------------------------------------------------
Master Supply Agreement                18            Diveo / Lucent Confidential
<PAGE>

                  nonperformance is a direct result of the other Party's failure
                  to perform its responsibilities, (ii) the Excused Party
                  provides such other Party with reasonable notice of such
                  nonperformance, and (iii) the Excused Party uses commercially
                  reasonable efforts to perform notwithstanding such other
                  Party's failure to perform. Such other Party shall compensate
                  the Excused Party for any documented, out of pocket additional
                  and reasonable costs and expenses incurred by the Excused
                  Party as a direct result of such other Party's failure to
                  perform, or delay in performing, its obligations under the
                  Agreement.

10.   CHARGES

      10.1. General.

            The charging mechanisms and pricing methodologies for Products,
            other Products and Services are expressly set forth in the
            Agreement. The Parties agree to supplement Schedule C in a manner
            consistent with the other pricing terms of this Agreement as
            necessary if and when Diveo purchases Products and Services for
            which pricing is not set forth in Schedule C. Diveo will not be
            liable to Lucent for any charges, additional or otherwise, for
            Products or Services provided by Lucent unless such charges are
            expressly set forth in a Purchase Order, this Agreement (including
            its Schedules) or as otherwise may be mutually agreed by the Parties
            in writing. As more definitively set forth in Schedule C, Lucent
            shall pay all Delivery Duty Paid (DDP) (as set forth in the ICC
            Incoterms 1990) related costs (i.e., transportation, insurance,
            customs duties and taxes) related to the shipment of Products (less
            the costs related to shipping FCA Miami which is included in the
            price for the Products) under this Agreement ("Incremental DDP
            Costs") and Diveo shall reimburse Lucent therefore on an
            Out-of-Pocket Expense basis (i.e., no mark-up).

      10.2. Taxes.

            The Parties' respective responsibilities for taxes arising under or
            in connection with this Agreement shall be as follows:

            (a)   Diveo shall bear all taxes, duties, levies and similar charges
                  (and any related interest and penalties), however designated,
                  imposed as a result of the existence or operation of this
                  Agreement, except (i) any tax imposed upon Lucent in a
                  jurisdiction other than the jurisdiction under the laws of
                  which Lucent was formed (hereinafter the "Resident
                  Jurisdiction") if such tax is allowable as a credit against
                  the Resident Jurisdiction income taxes of Lucent; and (ii) any
                  net income tax imposed upon Lucent by an government entity
                  within Lucent's Resident Jurisdiction. In order for the
                  exception contained in (i) to apply, Diveo must furnish Lucent
                  with such evidence as may be required by the Resident
                  Jurisdiction taxing authorities to establish that such tax has
                  been paid within thirty (30) days of issuance by the local
                  taxing authority so that Lucent may claim the credit.

            (b)   If Diveo is required to bear a tax, duty, levy or similar
                  charge pursuant to (a) above, then Diveo shall pay such tax,
                  duty, levy or similar charge and any additional amounts as are
                  necessary to ensure that the net amounts received by


- --------------------------------------------------------------------------------
Master Supply Agreement                19            Diveo / Lucent Confidential
<PAGE>

                  Lucent hereunder after all such payments or withholdings equal
                  the amounts to which Lucent is otherwise entitled under this
                  Agreement as if such tax, duty, levy or similar charge did not
                  exist.

            (c)   Each Party shall bear all wage withholding, social security
                  and other employment related taxes with respect to its
                  employees. In no event shall Diveo be liable to Lucent for any
                  ex-pat related costs or expenses beyond payment for the price
                  of Services and costs and expenses that Diveo is specifically
                  required to reimburse to Lucent pursuant to this Agreement, if
                  any.

            (d)   Lucent shall not collect an otherwise applicable tax if
                  Diveo's purchase is exempt from Lucent's collection of such
                  tax and a valid exemption certificate is furnished by Diveo to
                  Lucent.

            (e)   The Parties agree to cooperate with each other to minimize, to
                  the extent legally permissible, taxes arising under this
                  Agreement. Lucent's invoices shall separately state the
                  amounts of any taxes Lucent is collecting from Diveo. Each
                  Party shall provide and make available to the other any resale
                  certificates, information regarding out-of-state or
                  out-of-country sales or use of equipment, materials or
                  services, and other exemption certificates or information
                  reasonably requested by either Party.

      10.3. Incidental Expenses.

            Lucent acknowledges that all expenses that Lucent expects to incur
            in performing under this Agreement (including document reproduction
            and long-distance telephone) are included in Lucent's charges under
            in this Agreement. Accordingly, such Lucent expenses are not
            separately reimbursable by Diveo unless, on a case-by-case basis for
            unusual expenses, Diveo has agreed in advance and in writing to
            reimburse Lucent for the expense.

      10.4. Commitment.

            (a)   For purposes of this Agreement, "Commitment" shall mean
                  Diveo's agreement to issue and pay for Purchase Orders in
                  accordance with the terms of this Agreement for at least
                  twenty-five million dollars ($25,000,000) by the end of the
                  Initial Term subject to the provisions of this Section 10.4.

            (b)   Diveo shall be relieved from the Commitment:

                  (i)   By the total price (or portion thereof if only partially
                        terminated) of the Products and Services ordered under
                        any Purchase Order that are terminated in accordance
                        with Section 3.5 or Section 14.1;

                  (ii)  By the total price of any Product returned to Lucent for
                        failing to meet Acceptance in accordance with the terms
                        of this Agreement;

                  (iii) By the total price (or portion thereof if only partially
                        terminated) for Services ordered under a Purchase Order
                        that are terminated due to Lucent's failure to meet its
                        obligations under this Agreement; and


- --------------------------------------------------------------------------------

<PAGE>

                  (iv)  By the total amount of the Commitment not met if this
                        Agreement is terminated in accordance with Sections 14.1
                        or Section 14.3 prior to the expiration of the Initial
                        Term or by the total amount of the Commitment not met at
                        such time funding under the Credit Agreement is not
                        provided through no default of Diveo under the Credit
                        Agreement.

            (c)   In the event Diveo fails to issue and pay for Purchase Orders
                  to meet the Commitment (as such Commitment is reduced or
                  relieved as provided in Subsection (b) above, hereinafter the
                  "Adjusted Commitment") by the expiration of the Initial Term,
                  Diveo shall pay Lucent (from funds other than from the Lucent
                  financing) an amount equal to 50% of the difference between
                  the Adjusted Commitment and the total price for all Purchase
                  Orders issued and paid for by Diveo under this Agreement as of
                  the expiration date of Initial Term.

      10.5. Lucent-Provided Financing.

            (a)   Lucent shall provide Diveo financing in accordance with the
                  Credit Agreement and otherwise in accordance with the terms of
                  this Agreement.

            (b)   For purposes of this Agreement, "Lucent Content" shall refer
                  to (i) all Lucent Products and Services, (ii) all Harris
                  radios, radio accessories and antennae (collectively, the
                  "Harris Radios"), subject to the limitation set forth in
                  Section 10.5(d)(ii) below, and (iii) all Incremental DDP Costs
                  related to the foregoing. In the event Harris is no longer
                  selling radios that will work in the Diveo Network or Lucent
                  fails to Deliver Harris radios, radio accessories and
                  antennae, Diveo may change Harris with another radio
                  manufacturer.

            (c)   For purposes of this Agreement, "Non-Lucent Content" shall
                  refer to (i) all Third Party Content and other services
                  ordered under this Agreement (including all Services provided
                  by Diveo under subcontract with Lucent) and (ii) all
                  Incremental DDP Costs related to the foregoing.

            (d)   Lucent agrees to provide financing (subject to the terms and
                  conditions set forth in the Credit Agreement, including limits
                  on the total financing amounts) for all Lucent Content and
                  Non-Lucent Content. For purposes of this Subsection (d) (i)
                  "Total Contract Year Draw Down" shall refer to the total
                  dollar amount drawn down by Diveo under the Credit Agreement
                  during a Contract Year and (ii) "Delta" shall mean that amount
                  equal to the difference between the actual total amount drawn
                  down by Diveo for Lucent Content during a Contract Year and
                  the total amount Diveo would have been required to have drawn
                  down so that eighty percent (80%) of the Total Contract Year
                  Draw Down for such Contract Year was for Lucent Content (the
                  Delta can be a positive number if Diveo's draw down of Lucent
                  Content exceeds 80% or a negative number if Diveo's draw down
                  is below 80%).

                  (i)   Diveo may use up to eighty percent (80%) of the Total
                        Contract Year Draw Down during the each Contract Year
                        for Lucent Content and twenty percent (20%) of the Total
                        Contract Year Draw Down during each Contract Year for
                        Non-Lucent Content (up to fifty percent (50%) of

<PAGE>

                        which twenty percent may be used towards Services
                        provided by Diveo under subcontract with Lucent; Lucent
                        shall have no obligation to provide financing for any
                        Diveo-provided Services in excess of such fifty percent
                        maximum).

                  (ii)  As part of the Lucent Content, Diveo may use up to
                        twenty-five percent (25%) of the Total Contract Year
                        Draw Down during each Contract Year for Harris Radios.
                        In the event Diveo purchases Netro radios from Lucent,
                        the foregoing twenty-five percent will be reduced on a
                        pro rata basis based on the percentage of the Total
                        Contract Year Draw Down Diveo used for purchasing Netro
                        radios, but in no event shall the total percentage Diveo
                        may use for Harris Radios go below fifteen (15%) percent
                        of the Total Contract Year Draw Down.

                  (iii) Ninety (90) days prior to the end of each Contract Year
                        and at the end of each Contract Year, Lucent shall
                        provide for Diveo's review, and subject to Diveo's
                        confirmation, a reconciliation statement that specifies
                        the percentage of the Total Contract Year Draw Down (or
                        the then-current percentage for the statement provided
                        90 days prior to the end of the Contract Year) that was
                        used for Lucent Content and for Non-Lucent Content.

                        (1)   Where the actual percentage for Lucent Content
                              subject of the Total Contract Year Draw Down is
                              lower than eighty percent (80%) in any Contract
                              Year, Diveo shall have a sixty (60) day period
                              from receipt of the reconciliation statement to
                              place Purchase Orders in order to increase the
                              percentage for Lucent Content. If at the end of
                              such sixty day period the percentage for Lucent
                              Content is less than eighty percent (80%) (taking
                              into account the additional Purchase Orders issued
                              by Diveo during the sixty day period), Diveo shall
                              pay Lucent, as Lucent's sole and exclusive remedy,
                              a "Surcharge" calculated as follows: (A) if the
                              Delta is between $1 and $1,000,000, 25% of such
                              amount; (B) if the Delta is between $1 and
                              $5,000,0000, 25% for the first $1,000,000 plus 15%
                              for such amount over $1,000,000.01; and (C) if the
                              Delta is greater than $5,000,000.01, 25% for the
                              first $1,000,000 plus 15% for amounts between
                              $1,000,000.01 and $5,000,000 plus 5% for amounts
                              over $5,000,000.01. Diveo shall be entitled to
                              offset against any Surcharge payable by any
                              Surcharge Credits (as calculated below) Diveo has
                              at the time the Surcharge is payable.

                        (2)   Where the actual percentage for Lucent Content
                              subject of the Total Contract Year Draw Down is
                              greater than eighty percent (80%) in any Contract
                              Year, Diveo shall be entitled to a "Surcharge
                              Credit" calculated as follows: (A) if the Delta is
                              between $1 and $1,000,000, 25% of such amount; (B)
                              if the Delta is between $1 and $5,000,0000, 25%
                              for the first $1,000,000 plus 15% for such amount
                              over $1,000,000.01; and

<PAGE>

                              (C) if the Delta is greater than $5,000,000.01,
                              25% for the first $1,000,000 plus 15% for amounts
                              between $1,000,000.01 and $5,000,000 plus 5% for
                              amounts over $5,000,000.01. Diveo shall be
                              entitled to use all Surcharge Credits against any
                              Surcharges payable by Diveo in any Contract Year;
                              provided, however, that if at the end of the
                              Initial Term Diveo has any Surcharge Credits that
                              have not been off set against Surcharges, such
                              excess Surcharge Credits shall be automatically
                              extinguished, and Lucent shall have no liability
                              to Diveo with respect to such excess Surcharge
                              Credits.

            (e)   Subject to the terms set forth in Subsection (d) above, this
                  Agreement (including Schedule C) and the Credit Agreement,
                  Lucent shall provide financing and purchase Non-Lucent Content
                  on behalf of Diveo (e.g., Third Party Content and third party
                  and Diveo provided services). Such Non-Lucent Content needs to
                  be reasonable related to the Diveo Network. Lucent shall pay
                  all such delivered invoices in accordance with the payment
                  terms set forth on such invoice or as otherwise directed by
                  Diveo.

            (f)   Lucent shall continue to provide Diveo with financing for
                  Products and Services during the Disengagement Period as
                  described in Section 14.4(a) subject to the terms set forth in
                  Subsection (b) above and the terms of the Credit Agreement.

      10.6. Competitive Pricing.

            (a)   Lucent's prices, terms and conditions (including financing),
                  viewed collectively, to Diveo ("Diveo's Overall Terms") shall
                  be no less favorable than the prices, terms and conditions
                  (including financing, if any), viewed collectively, extended
                  by Lucent to another Lucent or Lucent Affiliate customer
                  (excluding Lucent Affiliates, distributors, resellers, sales
                  agents, and governmental entities) in an executed contract
                  during the Term of this Agreement ("Comparable Customer's
                  Overall Terms"), for comparable volumes, mix, and
                  configurations of Products and Services for similar use in a
                  country in the Territory (a "Comparable Purchase").

            (b)   If a Comparable Customer's Overall Terms for a Comparable
                  Purchase in any country in the Territory, are more favorable
                  than Diveo's Overall Terms for a Comparable Purchase in the
                  same country (the "Affected Country"), then Lucent shall
                  prospectively offer amended prices and/or amended terms and
                  conditions (the "Lucent Offer") to Diveo for Comparable
                  Purchases in the Affected Country only, such that Diveo's
                  Overall Terms shall be no less favorable than the Comparable
                  Customer's Overall Terms. Diveo shall have thirty (30) days
                  from receipt of the Lucent Offer to accept, in writing, such
                  Lucent Offer. In the event that Diveo accepts the Lucent
                  Offer, the Parties shall execute a corresponding amendment to
                  this Agreement, which amendment shall be effective as of the
                  date of Diveo's written acceptance of the Lucent Offer. In the
                  event that Diveo does not accept the Lucent Offer, the prices,
                  terms and conditions then in effect pursuant to this Agreement
                  shall remain in effect for all countries in the Territory.

                  first entry into a geographic or product market ("market entry
                  sales"), sales made as part of the settlement of a dispute,
                  sales involving an exchange or the granting of intellectual
                  property rights (other than the granting of licenses to use
                  software furnished by Lucent to the customer), or the
                  provision of laboratory, trial, test, demonstration or
                  promotional hardware, software or services.

            (d)   Upon Diveo's written request, Lucent shall certify in writing
                  after its fiscal close each calendar year its compliance with
                  the undertakings in this Section.

                  (ii)  Products without Installation Services. Lucent shall
                        invoice Diveo for Products ordered without installation
                        Services one hundred percent (100%) upon Delivery.

                  (iii) Services (other than Installation Services with Products
                        as provided above). Unless otherwise agreed upon by the
                        Parties (e.g., invoice based on meeting performance
                        milestones), Lucent shall invoice Diveo for Services
                        monthly in arrears. All invoices for Services to be
                        performed in any country other than the United States
                        shall be issued by the Lucent Affiliate in such country
                        to the Diveo entity on the Purchase Order. Such invoice
                        shall include invoice date, quantities, unit prices and
                        total amount due. Each invoice shall also indicate the
                        corresponding Purchase Order for each line item and the
                        corresponding milestone for each Service (if
                        applicable).

            (b)   All invoices shall be in United States dollars for Products
                  and United States based Services and in local currency for
                  locally provided Services. On each invoice, Lucent shall
                  include the calculations utilized to establish any charges,
                  and each invoice shall show details and information as to
                  charges as may be reasonably specified by Diveo, including as
                  necessary to satisfy Diveo's internal accounting; provided,
                  however, that to the extent that a firm pricing quotation
                  previously delivered to Diveo by Lucent expressly provides
                  such calculations, details and information, Lucent may
                  cross-reference such quotation in the applicable invoice in
                  lieu of including such calculations, details or information,
                  as applicable, in such invoice. Each invoice shall also (i)
                  separately state the amounts of any taxes Lucent is collecting
                  from Diveo and (ii) identify that the invoice is a
                  Lucent-issued invoice.

            (c)   To the extent a credit may be due Diveo pursuant to this
                  Agreement, Lucent shall provide Diveo with an appropriate
                  credit against amounts then due and owing. To the extent that
                  an amount due Diveo pursuant to this Agreement is not credited
                  or paid within sixty (60) days of becoming due, Lucent shall
                  pay such amounts to Diveo within thirty (30) calendar days
                  after such sixty-day period.

      11.2. Payment Due.

            (a)   Subject to the other provisions of this Article 11 and
                  Schedule C, charges shall be due and payable by Diveo in
                  accordance with the time period set forth in Schedule J after
                  receipt of a proper invoice for such amount (i.e., net
                  forty-five (45) days). Subject to the other terms of this
                  Article 11, in the event that any payments are not received by
                  Lucent within ten (10) days after written notice to Diveo by
                  Lucent indicating that such payments are due and owing and
                  unpaid, then commencing at the end of such ten (10) day
                  period, Diveo will also pay a late fee equal to the lesser of
                  (a) one (1) percent of the amount of such payment per month;
                  or (b) the maximum amount permissible by law.

            (b)   In the event that Diveo consistently and repeatedly fails to
                  pay material undisputed amounts due under Purchase Orders in
                  accordance with Subsection

                  (a) of this Section, and Diveo failure continues within sixty
                  (60) calendar days of notice from Lucent of such consistent
                  and repeated failures, then Lucent may, in addition to all
                  other remedies Lucent may have pursuant to this Agreement and
                  applicable law, condition acceptance of future Purchase Orders
                  on reasonable payment terms satisfactory to Lucent that
                  provide Lucent with reasonable assurances that it will be paid
                  in a satisfactory manner; provided, however, that such payment
                  terms shall be no less favorable to Diveo than prepayment in
                  full for such future Purchase Orders.

            (c)   All amounts due and payable to Lucent under this Article 11
                  shall be paid, at Diveo's option, (i) by check payable to the
                  order of Lucent, (ii) through draw-down of Lucent-provided
                  financing under the Credit Agreement, or (iii) by electronic
                  funds transfer to Lucent from account(s) designated by Diveo.

      11.3. Accountability.

            (a)   Lucent shall maintain complete and accurate records of and
                  supporting documentation for the amounts billable to, and
                  payments made by, Diveo for (i) Services billed on a time and
                  materials basis, (ii) incidental expenses payable by Diveo
                  pursuant to Section 10.3, and (iii) any Out-of-Pocket Expenses
                  or costs payable by, or other expenses reimbursable by, Diveo
                  pursuant to the Agreement. Lucent shall maintain such records
                  and supporting documentation in accordance with generally
                  accepted accounting principles applied on a consistent basis.

            (b)   Lucent agrees to provide Diveo with documentation and other
                  information with respect to each invoice as may be reasonably
                  requested by Diveo to verify accuracy and compliance with the
                  provisions of this Agreement.

            (c)   Upon Diveo's reasonable request, Diveo and its authorized
                  agents and representatives shall, at Lucent's option, (i)
                  receive copies of or (ii) have access to such records and
                  supporting documentation as described in Subsection (a) of
                  this Section for purposes of audit during normal business
                  hours during the Term and during the period for which Lucent
                  is otherwise required to maintain such records. Lucent shall
                  reasonably cooperate with Diveo or its designees in connection
                  with audits or examinations by regulatory authorities.

      11.4. Proration.

            Periodic charges under this Agreement are to be computed on a
            calendar month basis, and shall be prorated for any partial month.

      11.5. Set Off.

            With respect to any amount to be paid by Diveo hereunder, Diveo may
            set off against such amount any amount that Lucent is obligated to
            pay Diveo hereunder. With respect to any amount to be paid by Lucent
            hereunder for which Diveo has provided Lucent with notification that
            such amount is to be paid by Lucent, Lucent may set off against such
            amount any amount that Diveo is obligated to pay Lucent hereunder.

      11.6. Disputed Charges.

            Subject to Section 11.5, Diveo shall pay undisputed charges when
            such payments are due under this Article 11. Diveo may withhold
            payment of particular charges that Diveo disputes in good faith.
            Diveo shall notify Lucent of any disputed invoice amounts in
            accordance with Schedule J. In the event a dispute over an invoiced
            amount is resolved against Diveo, Diveo shall pay such amount within
            forty-five (45) days together with interest at the rate set forth in
            Section 11.2(a) from the original due date until the payment date.

      11.7. Encumbrances.

            Except to the extent granted in the Credit Agreement or otherwise
            expressly set forth in this Agreement, Lucent shall not perfect a
            security interest, lien or other encumbrance upon any Product,
            Product component or Service provided pursuant to this Agreement.

12.   CONFIDENTIALITY

      12.1. Confidential Information.

            Lucent and Diveo each acknowledge that they may be furnished with,
            receive, or otherwise have access to information of or concerning
            the other Party that such Party considers to be confidential,
            proprietary, a trade secret or otherwise restricted. As used in this
            Agreement and subject to Section 12.3, "Confidential Information"
            means all information, in any form, furnished or made available
            directly or indirectly by one Party (the "Disclosing Party") to the
            other (the "Receiving Party") that (i) concerns the operations,
            affairs and businesses of the Disclosing Party, the financial
            affairs of the Disclosing Party, the relations of the Disclosing
            Party with its customers, employees and service providers, and
            technical information of a Disclosing Party, or (ii) is marked
            confidential, restricted, proprietary, or with a similar
            designation. The terms and conditions of this Agreement shall be
            deemed Confidential Information.

      12.2. Obligations.


            The following obligations with respect to Confidential Information
            shall survive the expiration or termination of this Agreement for a
            period of seven (7) years or such longer period as required by
            regulation, law or court order.

            (a)   Each Party's Confidential Information shall remain the
                  property of that Party except as expressly provided otherwise
                  by the other provisions of this Agreement. Each Party shall
                  each use at least the same degree of care, but in any event no
                  less than a reasonable degree of care, to prevent unauthorized
                  disclosure of Confidential Information as it employs to avoid
                  unauthorized disclosure of its own information of a similar
                  nature. Except as otherwise permitted hereunder, the Parties
                  may disclose such information to entities performing services
                  required hereunder or to third party consultants, agents or
                  contractors where the entity or person agrees in writing to
                  assume the obligations substantially similar to those
                  described in this Section 12.2.

<PAGE>

            (b)   Each Party shall take reasonable steps to ensure that its
                  employees, consultants, agents and contractors comply with
                  this Section 12.2. In the event of any disclosure or loss of,
                  or inability to account for, any Confidential Information of
                  the Disclosing Party, the Receiving Party shall promptly, at
                  its own expense: (i) notify the Disclosing Party in writing;
                  (ii) take such actions as may be necessary and cooperate in
                  all reasonable respects with the Disclosing Party to minimize
                  the violation and any damage resulting therefrom.

      12.3. Exclusions.

            (a)   Confidential Information shall exclude any particular
                  information that the Receiving Party can demonstrate:

                  (i)   At the time of disclosure, was lawfully in the public
                        domain or in the possession of the Receiving Party;

                  (ii)  After disclosure, is lawfully published or otherwise
                        becomes part of the public domain through no fault of
                        the Receiving Party;

                  (iii) Was received after disclosure from a third party who had
                        a lawful right to disclose such information to the
                        Receiving Party without any obligation to restrict its
                        further use or disclosure;

                  (iv)  Was lawfully independently developed by the Receiving
                        Party without reference to Confidential Information of
                        the Disclosing Party; or

                  (v)   Was required to be disclosed to satisfy a legal
                        requirement of a competent government body; provided
                        that, immediately upon receiving such request and to the
                        extent that it may legally do so, the Receiving Party
                        advises the Disclosing Party promptly and prior to
                        making such disclosure in order that the Disclosing
                        Party may interpose an objection to such disclosure,
                        take action to assure confidential handling of the
                        Confidential Information, or take such other action as
                        it deems appropriate to protect the Confidential
                        Information.

            (b)   Either Party may disclose the terms and conditions of this
                  Agreement to third parties that (i) have expressed a bona fide
                  interest in consummating a significant financing, merger or
                  acquisition transaction between such third parties and such
                  Party, (ii) have a reasonable ability (financial and
                  otherwise) to consummate such transaction, and (iii) have
                  executed a nondisclosure agreement that includes within its
                  scope the terms and conditions of this Agreement and also
                  includes a procedure to limit the extent of copying and
                  distribution of this Agreement. Each Party shall endeavor to
                  delay the disclosure of the terms and conditions of this
                  Agreement until the status of discussions concerning such
                  transaction warrants such disclosure.

      12.4. No Implied Rights.

            Nothing contained in this Section shall be construed as obligating a
            Party to disclose its Confidential Information to the other Party,

            or as granting to or conferring on a Party, expressly or impliedly,
            any rights or license to the Confidential Information of the other
            Party.

            warranties and indemnities from the manufacturers, lessors or
            licensors of such items. Lucent shall pass through to Diveo the
            benefits of such warranties and indemnities to the extent that
            Lucent is permitted pursuant to any agreements between Lucent and
            such manufacturers, lessors or licensors. To the extent that Lucent
            is able to pass through to Diveo any such benefits, Diveo may
            enforce such benefits in Lucent's name, and Lucent shall reasonably
            cooperate with Diveo as necessary to permit Diveo to enforce such
            benefits.

                        by the requisite corporate action on the part of such
                        Party.

            (b)   Each Party represents and warrants to the other that it is not
                  subject to any contractual or other obligation that would

      13.5. Work Standards.

            (a)   Lucent covenants that the Services shall be rendered by Lucent
                  with promptness and diligence and shall be executed in a
                  workmanlike manner, in accordance with the practices and high
                  professional standards used in well-managed operations
                  performing services similar to the Services. Lucent covenants
                  that it shall use adequate numbers of qualified individuals

                  perform the Services.

                  support shall be provided on a 8 hour, 5-days-per-week basis
                  (provided that if Diveo purchases maintenance Services offered

                  7-days-per-week basis). Lucent shall provide a toll-free
                  number for Diveo's calls to Lucent.

            (g)   During the Warranty Period and any Extended Warranty Periods,

                  Software. Lucent shall implement all updates to all Lucent

                  incorporated into Schedule C subject to the following: Diveo
                  shall not be required to pay any additional charges relating
                  to that portion of an upgrade or new software release that (A)
                  constitutes an update, (B) reflects only an immaterial
                  enhancement or improvement in current functionality and not

                  or (C) is provided by Lucent to another customer as part of
                  the provision of software maintenance services under similar
                  terms and conditions. To the extent the upgrade or new
                  software release includes new functionality or materially
                  increased functional capacity and Diveo desires to take
                  advantage of same, Diveo shall pay a fair and competitive
                  price established at the time the upgrade or new software
                  release is implemented by Diveo or on Diveo's behalf and the

            (h)   During the Warranty Period and any Extended Warranty Periods,
                  Lucent shall provide access to technical resources to resolve
                  any problem with Products (other than Third Party Products)

                  including help desk support for problems that cannot be
                  remotely diagnosed and cured. If on-site support reveals that
                  the problem originated with Diveo or a third-party, Lucent may
                  charge Diveo reasonable time and material rates for the
                  on-site support.

            (i)   Subject to Section 19.9 of the Agreement, in the event that

                  will notify Lucent, specifying the nature of the failure in
                  reasonable detail. Lucent shall correct the failure at no
                  additional charge to Diveo so that the Product complies with
                  this Section 13.6. The Parties agree to follow the procedures

                  Product (based upon form, fit and function) this notification
                  period may vary but shall in no event be less than six (6)
                  months.

                  Period and Extended Warranty Period support during Extended

            environmental laws and regulations (collectively, "Laws") in effect
            as of the date of Delivery. Upon Diveo's request, Lucent will issue
            to Diveo written statements of compliance that Products provided to
            Diveo comply with the foregoing representation, warranty and
            covenant. Lucent agrees to provide any required changes to the

            the other Products recommended in writing by Lucent for inclusion in

            promptly cure such defect at Lucent's sole cost and expense. The
            Parties agree to follow the procedures established in Schedule H
            with respect to any warranty claims made by Diveo under this Section
            13.9.

            This warranty shall not apply to the extent that the applicable
            Lucent Product's failure to operate results from:

            (a)   the Lucent Products having been installed by a party other
                  than Lucent not in accordance with the Network Architecture
                  designed by Lucent, or Documentation and other advice and

                  interconnected to the Lucent Products or from such Third Party
                  Product's failure to operate in accordance with its
                  specifications;

            (c)   any changes made to the applicable portion of the Network
                  Architecture without Lucent's written recommendation or
                  approval;

            (f)   Diveo's failure to maintain the Lucent Product and the
                  applicable portion of the Network in accordance with Lucent's

            into any such Lucent Product or other Product that is not a Third
            Party Product either (i) prior to Delivery of such Lucent Product or
            Product to Diveo, or (ii) from any modification, upgrade,
            enhancement or new release to such Lucent Product or Product
            provided by Lucent, Lucent shall use all commercially reasonable
            efforts, at no additional charge, to assist Diveo in reducing the
            effects of the Virus and, if the Virus causes a loss of operational
            efficiency or loss of data, to assist Diveo to the same extent to

            termination of this Agreement (in whole or in part) for any reason,
            without Diveo's prior written consent.

                  PUNITIVE OR SPECIAL DAMAGES, INCLUDING, WITHOUT LIMITATION,
                  LOST REVENUES, LOST PROFITS AND SIMILAR DAMAGES EVEN IF SUCH
                  PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES IN
                  ADVANCE.

            (b)   Subject to Subsections (c) and (d) of this Section, each

            (c)   The limitation set forth in Subsection (b) of this Section
                  shall not apply with respect to: (i) damages occasioned by
                  willful misconduct, including abandonment or wrongful

                  be deemed direct damages.

      15.3. Force Majeure.

            (a)   No Party shall be liable for any default or delay in the
                  performance of its obligations under this Agreement if and to
                  the extent such default or delay is caused, directly or
                  indirectly, by fire, flood, lightning, earthquake, elements of
                  nature or acts of God, riots, civil disorders, rebellions or
                  revolutions in any country, with respect to Lucent, its sole
                  suppliers or its subcontractors, or any other cause beyond the
                  reasonable control of such Party; provided, however, that (i)
                  the non-performing Party is without fault in causing such
                  default or delay, and (ii) such default or delay could not
                  have been prevented by reasonable precautions and cannot
                  reasonably be circumvented by the non-performing Party through
                  the use of alternate sources, workaround plans or other means,
                  including to the extent contemplated by applicable disaster
                  recovery processes or procedures).

            (b)   In such event the non-performing Party shall be excused from
                  further performance or observance of the obligation(s) so
                  affected for as long as such circumstances prevail and such
                  Party continues to use commercially reasonable

                  efforts to recommence performance or observance whenever and
                  to whatever extent possible without delay. In addition, in
                  such event, Lucent shall give priority status to Diveo at
                  least as favorable as that given to other customers to
                  recommence performance or observance of its obligations. Any
                  Party so delayed in its performance shall immediately notify
                  the Party to whom performance is due by telephone (to be
                  confirmed in writing within two (2) business days of the
                  inception of such delay) and describe at a reasonable level of
                  detail the circumstances causing such delay.

            (c)   If any event under Subsection (a) of this Section above
                  substantially prevents, hinders, or delays Lucent's
                  performance for more than sixty (60) consecutive calendar
                  days, then at Diveo's option: (i) Diveo may terminate for
                  convenience at no charge to Diveo or modify any affected
                  portion of any Purchase Order, or terminate for convenience at
                  no charge to Diveo any affected portion of this Agreement, and
                  the charges payable hereunder shall be equitably adjusted to
                  reflect such termination; or (ii) Diveo may terminate this
                  Agreement without liability to Diveo or Lucent as of a date
                  specified by Diveo in a written notice of termination to
                  Lucent. Lucent shall not have the right to any additional
                  payments from Diveo for costs or expenses incurred by Lucent
                  as a result of any force majeure occurrence.

      16.4. Indemnification Procedures.

            With respect to third-party claims, the following procedures shall
            apply:

            (a)   Promptly after receipt of notice of the commencement or
                  threatened commencement of any civil, criminal,
                  administrative, or investigative action or proceeding
                  involving a claim in respect of which Indemnitee will seek
                  indemnification pursuant to this Article 16, Indemnitee will
                  notify Indemnitor of such claim in writing. No failure to so
                  notify Indemnitor will relieve Indemnitor of its obligations
                  under this Agreement except to the extent that it can
                  demonstrate damages attributable to such failure. Within
                  fifteen (15) calendar days following receipt of written notice
                  from Indemnitee relating to any claim, but no later than ten
                  (10) calendar days before the date on which any response to a
                  complaint or summons is due, Indemnitor will notify Indemnitee
                  in writing if Indemnitor elects to assume control of the
                  defense and settlement of that claim (a "Notice of Election").

            (b)   If Indemnitor delivers a Notice of Election relating to any
                  claim within the required notice period, Indemnitor shall be
                  entitled to have sole control over the defense and settlement
                  of such claim; provided that (i) Indemnitee shall be entitled
                  to participate in the defense of such claim and to employ
                  counsel at its own expense to assist in the handling of such
                  claim, and (ii) Indemnitor shall obtain the prior written
                  approval of Indemnitee before entering into any settlement of
                  such claim or ceasing to defend against such claim if such
                  settlement or ceasing to defend shall have a material impact
                  on the Indemnitee. After Indemnitor has delivered a Notice of
                  Election relating to any claim in accordance with the
                  preceding paragraph, Indemnitor shall not be liable to
                  Indemnitee for any legal expenses incurred by Indemnitee in
                  connection with the defense of that claim. In addition,
                  Indemnitor shall not be required to indemnify Indemnitee for
                  any amount paid or payable by the Indemnitee in the settlement
                  of any claim for which the Indemnitor has delivered a timely
                  Notice of Election if such amount was agreed to without the
                  written consent of the Indemnitor.

            (c)   If Indemnitor does not deliver a Notice of Election relating
                  to any claim within the required notice period, Indemnitee
                  shall have the right to defend the claim in such manner as it
                  may deem appropriate, at the cost and expense of Indemnitor.
                  Indemnitor shall promptly reimburse Indemnitee for all such
                  costs and expenses.

17.   DISPUTE RESOLUTION

      Any dispute between the Parties arising out of or relating to this
      Agreement, including with respect to the interpretation of any provision
      of this Agreement and with respect to the performance by Lucent or Diveo,
      shall be resolved as provided in this Article 17.

      17.1. Informal Dispute Resolution.

            (a)   Prior to the initiation of formal dispute resolution
                  procedures, the Parties shall first attempt to resolve their
                  dispute informally pursuant the escalation procedures set
                  forth in Schedule I. In connection with such escalation
                  process:

                  (i)   The designated representatives shall meet as often as
                        the Parties reasonably deem necessary in order to gather
                        and furnish to the other all information with respect to
                        the matter in issue which the Parties believe to be
                        appropriate and germane in connection with its
                        resolution. The representatives shall discuss the
                        problem and attempt to resolve the dispute without the
                        necessity of any formal proceeding.

                  (ii)  During the course of discussion, all reasonable requests
                        made by one Party to another for non-privileged
                        information, reasonably related to this Agreement, shall
                        be honored in order that each of the Parties may be
                        fully advised of the other's position.

                  (iii) The specific format for the discussions shall be left to
                        the discretion of the designated representatives.

            (b)   The Parties agree that disputes, controversies or claims
                  between them shall not be subject to the provisions of this
                  Section where:

                  (i)   A Party makes a good faith determination that a breach
                        of the terms of this Agreement by the other Party is
                        such that a temporary restraining order or other
                        injunctive relief is the only appropriate and adequate
                        remedy; or

                  (ii)  Institution of formal proceedings earlier than as set
                        forth in Section 17.2(a) is necessary to avoid the
                        expiration of any applicable limitations period or to
                        preserve a superior position with respect to other
                        creditors.

            (c)   If a Party files a pleading with a court seeking immediate
                  injunctive relief and this pleading is challenged by the other
                  Party and the injunctive relief sought is not awarded in
                  substantial part, the Party filing the pleading seeking
                  immediate injunctive relief shall pay all of the costs and
                  attorneys' fees of the Party successfully challenging the
                  pleading.

      17.2. Litigation.

            (a)   Formal proceedings for the resolution of a dispute may be
                  commenced after the earlier of:


- --------------------------------------------------------------------------------
Master Supply Agreement                40            Diveo / Lucent Confidential
<PAGE>

                  (i)   The designated representatives described in Section 17.1
                        conclude in good faith that amicable resolution through
                        continued negotiation of the matter does not appear
                        likely; or

                  (ii)  Thirty (30) calendar days after the initial written
                        request to appoint a designated representative pursuant
                        to Subsection 17.1(a) above (this period shall be deemed
                        to run notwithstanding any claim that the process
                        described in this Section 17.1 was not followed or
                        completed).

            (b)   The Parties consent to the jurisdiction of the courts of the
                  State of Florida (and to venue in Dade County), and to
                  jurisdiction and venue in the United States District Court for
                  the Southern District of Florida for all litigation that may
                  be brought with respect to the terms of, and the transactions
                  and relationships contemplated by, this Agreement. The Parties
                  further consent to the jurisdiction of any state court located
                  within a district that encompasses assets of a Party against
                  which a judgment has been rendered for the enforcement of such
                  judgment or award against the assets of such Party.

      17.3. Continued Performance.

            Each Party agrees to continue performing its obligations under this
            Agreement while any dispute is being resolved except to the extent
            the issue in dispute precludes performance.

      17.4. Governing Law.

            This Agreement and performance under it shall be governed by and
            construed in accordance with the laws of the State of New York
            without regard to its choice of law principles.

18.   INSURANCE REQUIREMENTS

      During the Term, Lucent shall have and maintain in force the following
      insurance coverages:

            (a)   Worker's Compensation and Employer's Liability as prescribed
                  by the law of the State or Nation in which the work is
                  performed. Lucent reserves the right to self-insure where
                  allowed by law.

            (b)   General Liability, including Products and Completed Operations
                  Liability, with a combined single limit for bodily injury and
                  property damage of at least US$ 1,000,000 for each occurrence.

            (c)   Automobile Liability if the use of motor vehicles is required
                  with a combined single limit of liability of at least US$
                  1,000,000 for each occurrence for vehicles operated in the
                  United States of America. For vehicles operated outside of the
                  United States of America, the limits of liability will be in
                  accordance with local legal requirements and sufficient to
                  meet normal and customary claims.


      The foregoing insurance coverages shall be primary and non-contributing
      with respect to any other insurance or self insurance that may be
      maintained by Diveo. Lucent shall cause its insurers to issue certificates
      of insurance evidencing that the coverages and policy endorsements

Master Supply Agreement                41            Diveo / Lucent Confidential
<PAGE>

      required under this Agreement are maintained in force and that not less
      than thirty (30) calendar days written notice shall be given to Diveo
      prior to any modification, cancellation or non-renewal of the policies.
      The minimum limits of coverage specified herein are not intended, and
      shall not be construed, to limit any liability or indemnity of Lucent
      under this Agreement.

19.   GENERAL

      19.1. Binding Nature and Assignment.

            (a)   This Agreement shall accrue to the benefit of and be binding
                  upon the Parties hereto and any purchaser or any successor
                  entity into which either Party has been merged or consolidated
                  or to which either Party has sold or transferred all or
                  substantially all of its assets.

            (b)   Neither Party may, or shall have the power to, assign this
                  Agreement or delegate such Party's obligations hereunder
                  without the prior written consent of the other, which consent
                  shall not be unreasonably withheld, except that either Party
                  may assign its rights and obligations under this Agreement
                  without the approval of the other Party to

                  (i)   an entity which acquires all or substantially all of the
                        assets of the Party,

                  (ii)  to any Affiliate, or

                  (iii) to a successor in a merger or acquisition of the Party;

                  provided, however, that in the event that the financing
                  provided by Lucent under the Credit Agreement is terminated as
                  a result of such assignment, then Lucent's consent to such
                  assignment shall be required if the entity has credit
                  worthiness less than that of Diveo.

      19.2. Entire Agreement.

            This Agreement, including any attached Schedules, constitutes the
            entire agreement between the Parties with respect to the subject
            matter in this Agreement, and supersedes all prior agreements,
            whether written or oral, with respect to the subject matter
            contained in this Agreement.

      19.3. Notices.

            All notices, requests, demands, and determinations under this
            Agreement (other than routine operational communications), shall be
            in writing and shall be deemed duly given (i) when delivered by
            hand, (ii) one (1) business day after being given to an express,
            overnight courier with a reliable system for tracking delivery,

            A Party may from time to time change its address or designee for
            notification purposes by giving the other prior written notice of
            the new address or designee and the date upon which it will become
            effective.

      19.4. Counterparts.

            This Agreement may be executed in several counterparts, all of which
            taken together shall constitute one single agreement between the
            Parties hereto.

      19.5. Relationship of Parties.

            Lucent, in furnishing Products and Services hereunder, is acting as
            an independent contractor, and Lucent personnel (including its
            subcontractors) shall not be considered or represented as employees
            or agents of Diveo. Lucent is not otherwise an agent of Diveo and
            has no authority to represent Diveo as to any matters, except as
            expressly authorized in this Agreement. Lucent is solely responsible
            for: (a) performing its responsibilities under this Agreement, (b)
            management and control of its personnel; (c) the payment of all
            compensation owed to its personnel, including payment of
            employment-related taxes, benefits, and worker's compensation
            insurance; (d) the filing of all required employment returns and
            reports; and (e) the withholding and payment of all applicable
            federal, state, and local taxes and other wage or employment
            assessments, including but not limited to income tax, social
            security tax, and unemployment insurance premiums for its personnel.

      19.6. Severability.

            In the event that any provision of this Agreement conflicts with the
            law under which this Agreement is to be construed or if any such
            provision is held invalid by an arbitrator or a court with
            jurisdiction over the Parties, such provision shall be deemed to be
            restated to reflect as nearly as possible the original intentions of
            the Parties in accordance with applicable law. The remainder of this
            Agreement shall remain in full force and effect.

      19.7. Consents and Approval.

            Except where expressly provided as being in the sole discretion of a
            Party, where agreement, approval, acceptance, consent, or similar
            action by either Party is required


- --------------------------------------------------------------------------------
Master Supply Agreement                43            Diveo / Lucent Confidential
<PAGE>

            under this Agreement, such action shall not be unreasonably delayed
            or withheld. An approval or consent given by a Party under this
            Agreement shall not relieve the other Party from responsibility for
            complying with the requirements of this Agreement, nor shall it be
            construed as a waiver of any rights under this Agreement, except as
            and to the extent otherwise expressly provided in such approval or
            consent.

      19.8. Waiver of Default.

            No waiver or discharge hereof shall be valid unless in writing and
            signed by an authorized representative of the Party against which
            such amendment, waiver, or discharge is sought to be enforced. A
            delay or omission by either Party hereto to exercise any right or
            power under this Agreement shall not be construed to be a waiver
            thereof. A waiver by either of the Parties hereto of any of the
            covenants to be performed by the other or any breach thereof shall
            not be construed to be a waiver of any succeeding breach thereof or
            of any other covenant herein contained.

      19.9. Cumulative Remedies.

            Except as otherwise expressly provided herein, all remedies provided
            for in this Agreement shall be cumulative and in addition to and not
            in lieu of any other remedies available to either Party at law, in
            equity or otherwise.

      19.10. Survival.

            Any provision of this Agreement which contemplates performance or
            observance subsequent to any termination or expiration of this
            Agreement (in whole or in part) shall survive any termination or
            expiration of this Agreement (in whole or in part, as applicable)
            and continue in full force and effect. Without limiting the
            generality of the foregoing, Diveo shall have the right to extend
            any Warranty Period or Extended Warranty Periods in accordance with
            the terms of this Agreement and purchase Products and Services
            pursuant to Section 2.2, and each Party's obligations with respect
            to such Products and Services shall survive expiration or
            termination of this Agreement (in whole or in part, as applicable)
            and continue in full force and effect.

      19.11. Public Disclosures.

            All media releases, public announcements, and public disclosures
            relating to this Agreement or the subject matter of this Agreement,
            including promotional or marketing material, but not including
            announcements intended solely for internal distribution or
            disclosures to the extent required to meet legal or regulatory
            requirements beyond the reasonable control of the disclosing Party,
            shall be coordinated with and shall be subject to approval by the
            non-disclosing Party prior to release. In the event Diveo is going
            to file this Agreement as part of public securities filing, Diveo
            will notify Lucent to enable Lucent to provide prompt input to limit
            the extent of the disclosure; provided, however, Diveo shall not be
            required to delay any required filings and Diveo shall ultimately
            determine what will be disclosed.

<PAGE>

      19.12. Service Marks.

            Each Party agree that it shall not, without the other Party's
            written consent, use the name, service marks or trademarks of the
            other Party or its Affiliates.

      19.13. Third Party Beneficiaries.

            Except as otherwise provided in this Agreement, this Agreement shall
            not be deemed to create any rights in third parties, including
            suppliers and customers of a Party, or to create any obligations of
            a Party to any such third parties.

      19.14. Amendment.

            This Agreement shall not be modified, amended or in any way altered
            except by an instrument in writing signed by both Parties.

      19.15. Interpretation

            (a)   Terms other than those defined in this Agreement shall be
                  given their plain English meaning, and those terms, acronyms
                  and phrases known in the telecommunications and information
                  technology services industries shall be interpreted in
                  accordance with their generally known meanings. Unless the
                  context otherwise requires, words importing the singular
                  include the plural and vice-versa. Terms defined in the Credit
                  Agreement shall not be superceded by the same terms defined in
                  this Agreement.

            (b)   References to "Article", "Section", "Subsection" and
                  "Schedule" mean references to an article, section, subsection
                  or schedule of this Agreement, as appropriate, unless
                  otherwise specifically stated.

            (c)   The article and section headings in this Agreement are
                  intended to be for reference purposes only and shall in no way
                  be construed to modify or restrict any of the terms or
                  provisions of this Agreement.

            (d)   The words "include," "includes", and "including", when
                  following a general statement or term, are not to be construed
                  as limiting the general statement or term to any specific item
                  or matter set forth or to similar items or matters, but rather
                  as permitting the general statement or term to refer also to
                  all other items or matters that could reasonably fall within
                  its broadest scope.

            (e)   All dollar amounts set forth herein are in United States
                  dollars.

            (f)   Unless otherwise specified as "business days", reference to
                  "days" in this Agreement shall refer to calendar days.

      19.16. Incorporation by Reference and Order of Precedence.

            (a)   All Schedules attached hereto are hereby incorporated by
                  reference into this Agreement. Subject to Section 19.14, any
                  amendments to this Agreement (including with respect to
                  Schedules), and any additional Schedules that are

                  shall likewise be incorporated by reference into this
                  Agreement.

            (b)   Any conflict among or between the documents making up this
                  Agreement will be resolved in accordance with the following
                  order of precedence (in descending order of precedence):

            facilities reasonably required in connection with Lucent's
            performance of its obligations under this Agreement. No charge shall
            be made for such access.

      19.18. Export Control

            The Parties acknowledge that any Products provided under this
            Agreement are subject to U.S. export laws and regulations, and any
            use or transfer of such Products must be authorized under those
            regulations. Each Party agrees that it will not ship, Deliver, use,
            distribute, transfer, or transmit the Products (even if incorporated
            into other Products) in violation of such laws and regulations. If
            requested by a Party, the other Party shall sign written assurances
            and other export-related documents as may be required by the
            requesting Party to comply with such laws and regulations.


IN WITNESS WHEREOF, this Agreement has been executed and delivered by the
undersigned officers, thereunto, duly authorized, as of the date first written
above.

agree, upon request of the Independent Third Party, to provide the Independent
Third Party with additional time to make its determination, which agreement
shall not be unreasonably withheld). Buyer and Sellers will each bear 50% of the
fees of the Independent Third Party for such determination.

          (d) Within five days after final determination of the Final Purchase
Price Adjustment, (i) if such adjustment is an increase, Buyer shall pay Sellers

be released from escrow and paid to Buyer and Sellers shall pay any additional
shortfall to Buyer in U.S. Dollars in immediately available funds in accordance

Dollars (US $10,000), (i) the portion of the Purchase Price to be placed in
escrow shall be increased by an amount equal to such excess, which shall consist
of Diginet Stock based upon a value of $1.81 per share (and the aggregate number

reduced accordingly), (ii) the Escrow Period (as defined in the Escrow
Agreement) shall be extended, only for this Additional Escrow,  from the six
month anniversary of the Closing Date to the first anniversary of the Closing
Date and (iii) the Escrow Agreement shall be revised to take into account the
foregoing; provided, that, in no event shall the Escrow Fund (as defined in the
           --------  ----
Escrow Agreement) exceed One Million Two Hundred Fifty Thousand U.S. Dollars (US

available and that, even if available, such exemption may not allow such Seller
to transfer all or any portion of such Diginet Stock and Promissory Note under
the circumstances, in the amounts or at the times such Seller might propose.

          (e) Such Seller understands that no public market now exists for the
Diginet Stock or Promissory Note to be acquired by him hereunder and that Buyer
is uncertain whether a public market will ever exist for such Diginet Stock or
Promissory Note.

specified limitations.

warranties of Buyer set forth in Section 5 hereof, such Seller has had an
opportunity to discuss in detail Diginet's and Buyer's business, management and
financial affairs with Diginet's and Buyer's officers and management employees
and has carefully reviewed the representations made herein and all documents and
records of Diginet and Buyer which Diginet or Buyer has provided in response to
such Seller's requests.

          (i) (A)  Such Seller hereby certifies that he is not a "U.S. person"
as that term is defined in Rule 902(k) of Regulation S under the Securities Act
("Regulation S") and is not acquiring the Diginet Stock for the account or
  ------------
benefit of a "U.S. person;" (B) such Seller acknowledges that the issuance of
the Diginet Stock constitutes an "offshore transaction" as that term is defined

registration statement under the Securities Act or pursuant to an available
exemption from registration; (D) such Seller agrees not to engage in hedging
transactions with regard to the Diginet Stock unless in compliance with the

provisions of subsections (C) and (D) above, provided, however, that if

Diginet Stock not made in accordance with the provisions of subsections (C) and

12.  INDEMNIFICATION; REMEDIES

            (a)  Notwithstanding any investigation by Buyer or Diginet, or any
information obtained pursuant thereto, Buyer and Diginet shall be entitled to
rely upon the representations and warranties of the Company and Sellers
contained in this Agreement or any other agreement, document, certificate,

action based upon or arising out of a breach of a representation or
warranty made hereunder must be made within the Survival Period applicable
thereto or the party against which such claim is made shall have no
liability with respect thereto.  Nothing combined in this Section, however,
shall affect the obligations of any party to perform the agreements and
covenants to be performed on its part hereunder or in connection herewith
either before or after the Closing Date.

    12.2. Sellers Indemnification Obligations

          (a)  Subject to the provisions of this Section 12, Sellers hereby

<PAGE>

the "Buyer Indemnified Persons") from and against any and all costs, expenses,
     -------------------------
losses, interest charges, penalties, damages or other liabilities or

                                                                  -----
Damages") incurred by any Buyer Indemnified Person, directly or indirectly,
- -------
by reason of, resulting from or relating to (i) any breach of any
representation or warranty, or breach or violation of any of the covenants
or agreements of the Company or any Seller in this Agreement or any Company
Closing Document or any Seller Closing Document or (ii) any Tax liability
of INEA S.R.L.

          (b)  Sellers hereby irrevocably waive any and all right to recourse

under this Section 12, including, without limitation and right to contribution
from, subrogation to or recovery against the Company with respect to any
such obligations.

                                                                 ------
Indemnified Persons") from and against any and all costs, expenses, losses,
- -------------------
interest charges, penalties, damages or other liabilities or obligations,
including reasonable attorneys fees (collectively, "Seller Damages") incurred by
                                                    --------------
any Seller Indemnified Person, directly or indirectly, by reason of or resulting
from any breach of any representation or warranty, or breach or violation of any
covenants or agreements of Buyer or Diginet in this Agreement, any Buyer Closing
Document or any Diginet Closing Document.

    12.4.  Conditions of Indemnification

           The obligations and liabilities of Sellers, Buyer and Diginet under
this Section 11 shall be subject to the following terms and conditions:

           (a)  The indemnified party shall give prompt written notice to the
indemnifying party of any Proceeding or other event which may give rise to
liability of the indemnifying party pursuant to this Section 12 (an "Indemnity
                                                                     ---------
Claim"); provided, however, that failure to give such notice shall not relieve
- -----
the indemnifying party of its obligations hereunder unless the indemnifying
party shall have suffered actual material damage as a result of such failure.

            (b)  With respect to Indemnity Claims involving matters asserted by
third parties, the indemnified party may engage representatives of its own
choosing with respect to any such Indemnity Claim, such representation
(including the compromise or settlement of any such Indemnity Claim) to be
undertaken on behalf of and for the account and risk of the indemnifying party.
In the event the indemnified party elects not to undertake such defense by its
own Representatives, the indemnified party shall give prompt written notice of

                                       46
<PAGE>

such election to the indemnifying party, and the indemnifying party will
undertake the defense (including the compromise or settlement) thereof by
Representatives designated by it whom the indemnified party determines in
writing to be satisfactory for such purposes.  The consent of the indemnified
party to the indemnifying party's choice of counsel or other representative
shall not be unreasonably withheld.  No party shall compromise or settle an
Indemnity Claim without the written consent of the other relevant party, which
consent shall not be unreasonably withheld, conditioned or delayed.

            (c)  With respect to an Indemnity Claim not involving a third
party, if the indemnifying party objects to such Indemnity Claim the
indemnifying party shall give the indemnified party written notice thereof
within fifteen (15) days following his or its receipt of notice of an
Indemnity Claim pursuant to Section 12.4(a) stating the basis for such
indemnifying party's objection.  Failure to give such notice shall constitute
acceptance by the indemnifying party of such Indemnity Claim.  In the event
the indemnified party and the indemnifying party are unable to resolve their
dispute within thirty (30) days following the receipt by the indemnified
party's notice of the indemnifying party's objection to such Indemnity Claim,
the parties shall submit their dispute to binding arbitration (i) to be held
in New York, New York pursuant to the Commercial Arbitration Rules of the
International Chamber of Commerce by three arbitrators appointed in
accordance with such rules, if the value of the disputed Indemnity Claim is
greater than or equal to U.S. $200,000 or (ii) to the Arbitration Tribunal
of the Mercantile Exchange for the City of Buenos Aires pursuant to the
rules of such tribunal by a three person panel appointed in accordance with
such rules, if the value of such disputed Indemnity Claim is less than U.S.
$200,000.  English shall be the language of any arbitration which takes
place in New York and Spanish shall be the language of any arbitration
which takes place in Buenos Aires.  Costs of the arbitration shall be
shared equally by the parties and each party shall pay its own attorneys'
fees and other expenses, except that the arbitrators may impose all or part
of the defending party's costs, fees and expenses against the party
bringing a claim if the arbitrators determine that there was no reasonable
basis for pursuing such a claim.  All testimony shall be transcribed, and
any award shall be accompanied by written findings of fact and a written
statement of reasons for the decision.

    12.5. Limitations on Liability

          (a)  No amount shall be payable in indemnification by any
indemnifying party under this Section 12 unless the aggregate Buyer Damages
suffered by the Buyer Indemnified Persons or the Aggregate Seller Damages
suffered by the Seller Indemnified Persons, as applicable, in respect of which
such indemnifying party would be liable under this Section 12 exceed Fifty
Thousand Dollars ($50,000) (the "Deductible"); provided however that, the
                                 ----------    -------- -------
Deductible shall not apply to (i) any claim based upon any
misrepresentation or breach of a representation or warranty which was
actually known to be untrue by the indemnifying party when made or asserted,
(ii) any claim for indemnity with respect to Taxes or (iii) any claim for

                                       47
<PAGE>

indemnity under Section 4.7 or Section 5.4.  In the event Aggregate Buyer
Damages or Aggregate Seller Damages, as applicable, exceed the Deductible,
the indemnified party shall be entitled to seek indemnification for all
Buyer Damages or Seller Damages, as applicable, in excess thereof.

          (b)  Except with respect to Indemnity Claims arising out of any
breach of any representation and warranty set forth in Section 3.10, 3.12,
3.13, 3.21 or 4.2, the aggregate indemnification payable in each case by
Sellers, on the one hand, and by Buyer and Diginet, on the other hand, shall
not exceed the Purchase Price.

    12.6. Escrow; Right of Set-off

          Upon notice to Sellers specifying in reasonable detail the basis for
such set-off, Buyer may set off any amount to which it may be entitled under
this Section 12 against amounts otherwise payable under the Promissory Notes or
may give notice of a claim for such amount under the Escrow Agreement.  The
exercise of such right of set-off by Buyer in good faith, whether or not
ultimately determined to be justified, will not constitute an event of default
under the Promissory Notes or any instrument securing a Promissory Note.
Neither the exercise of nor the failure to exercise such right of set-off or to
give a notice of a claim under the Escrow Agreement will constitute an election
of remedies or limit Buyer in any manner in the enforcement of any other
remedies that may be available to it.

    12.7. Exclusive Remedy

          The parties acknowledge that, except in the case of fraud, their sole
remedy after the Closing for any breach of any representation or warranty
contained in this Agreement shall be the indemnification provisions set forth in
this Section 12.  Notwithstanding the foregoing, nothing herein shall be
construed or interpreted as limiting or impairing the rights or remedies that
any party hereto may have at equity, including, but not limited to, specific
performance and injunctive relief, where available.

13.  TERMINATION

    13.1. Termination Events

          This Agreement may be terminated:

          (a)  by mutual consent of Buyer and Sellers;

          (b)  by Buyer, upon written notice to Sellers at any time prior to
the Closing, if Buyer, in its reasonable discretion, is not satisfied with the
results of its due diligence investigation of Sellers, the Company or of INEA
S.R.L. (as described in Section 2.6).

                                       48
<PAGE>

          (c)  by Buyer, upon written notice, to Sellers, if there has been a
breach by the Company or any Seller of any of its or his respective
representations, warranties, covenants or agreements contained herein, or any
such representation or warranty shall have become untrue, in any such case such
that any of the conditions set forth in Article 10 will not be satisfied,
and such breach or condition has not been cured within ten days following
receipt by the breaching party of written notice of such breach;

          (d)  by Sellers upon written notice to Buyer if there has been a
breach by Buyer or Diginet of any of its respective representations,
warranties, covenants or agreements contained herein, or any such representation
or warranty shall have become untrue, in any such case such that any of the
conditions set forth in Article 11 will not be satisfied, and such breach or
condition has not been cured within ten days following receipt by the breaching
party of written notice of such breach.

          (e)  by either Buyer or Sellers if the Closing has not occurred
(other than through the failure of any party seeking to terminate this Agreement
to comply fully with its obligations under this Agreement) on or before April
30, 2000, or such later date as the parties may agree upon.

    13.2. Effect of Termination

          If this Agreement is terminated pursuant to Section 13.1, this
Agreement shall forthwith become wholly void and of no effect, and the parties
shall be released from all future obligations hereunder; provided, however, that
the obligations in Sections 14.1 and 14.2 shall not be extinguished but shall
survive such termination; provided further, however, that if this Agreement is
                          -------- -------
terminated by a party because of the breach of this Agreement by the other party
or because one or more of the conditions to the terminating party's obligations
under this Agreement is not satisfied as a result of the other party's failure
to comply with its obligations under this Agreement, the terminating party's
right to pursue all legal remedies will survive such termination unimpaired.  In
the event of any termination of this Agreement, Buyer shall notify the Secretary
of Communications of Argentina thereof and take such other actions reasonably
required to withdraw any pending application with such Secretary for consent to
a change of control of the Licenses as a result of the transactions contemplated
by this Agreement.

14. GENERAL PROVISIONS

    14.1. Expenses

each Seller, Buyer and Diginet hereby accepts and consents to the jurisdiction

service shall be deemed complete upon delivery thereof to the Process Agent,
provided that in the case of any such service upon the Process Agent, the party
effecting such service shall also deliver a copy thereof to each party in the

effect or to appoint another agent, who will thereafter be referred to herein as
the "Process Agent," so that such party will at all times have an agent for
     -------------
service of process for the above purposes in New York, New York.  In the event
of the transfer of all or substantially all of the assets and business of the

Agent with the same effect as if named herein in place of CSC Corporation or
appointed in place of such other agent that may have been appointed.  Nothing
herein shall affect the right of any party to serve process in any other manner
permitted by applicable law.  Each party expressly acknowledges that the
foregoing waiver is intended to be irrevocable under the laws of the State of
New York and of the United States of America.  The Process Agent must notify to
each of the Seller to the following adreess: Viamonte street 1145, 10 "A" floor,

further information, (b) to execute and deliver to each other such other
documents, and (c) to do such other acts and things, all as the other party may
reasonably request for the purpose of carrying out the intent of this Agreement
and the documents referred to in this Agreement.

    14.6.  Waiver

           The rights and remedies of the parties to this Agreement are
cumulative and not alternative.  Neither the failure nor any delay by any party
in exercising any right, power, or privilege under this Agreement or the Company
Closing Documents, the Seller Closing Documents, the Buyer Closing Documents or
the Diginet Closing Documents, as applicable, will operate as a waiver of such
right, power, or privilege, and no single or partial exercise of any such right,
power, or privilege will preclude any other or further exercise of such right,
power, or privilege or the exercise of any other right, power, or privilege.  No
single or partial exercise of any such right, power or privilege shall preclude
the further exercise of such right, power or privilege, or the exercise of any
other right, power or privilege.  To the maximum extent permitted by applicable
law, (a) no claim or right arising out of this Agreement or the Company Closing
Documents, the Seller Closing Documents, the Buyer Closing Documents or the
Diginet Closing Documents, as

                                       53
<PAGE>

applicable, can be discharged by one party, in whole or in part, by a waiver or
renunciation of the claim or right unless in writing signed by the other party;
(b) no waiver that may be given by a party will be applicable except in the
specific instance for which it is given; and (c) no notice to or demand on one
party will be deemed to be a waiver of any obligation of such party or of the
right of the party giving such notice or demand to take further action without
notice or demand as provided in this Agreement or the Company Closing Documents,
the Seller Closing Documents, the Buyer Closing Documents or the Diginet Closing
Documents, as applicable.

    14.7.  Entire Agreement and Modification

           This Agreement, including the Schedules and Exhibits hereto and
Company Closing Documents, the Seller Closing Documents, the Buyer Closing
Documents or the Diginet Closing Documents, as applicable, supersedes all prior
agreements between the parties with respect to its subject matter (including the
Letter of Intent between Buyer and Sellers dated January 3, 2000) and
constitutes the entire agreement among the parties with respect to its subject
matter.  This Agreement may not be amended except by a written agreement
executed by the party to be charged with the amendment.

    14.8.  Binding Effect

representatives and permitted assigns.

    14.9.  Assignment

           No party may assign its rights or obligations hereunder without the

unreasonably withheld, conditioned, or delayed, except that (a) Diginet may
assign all of its rights and obligations hereunder in connection with a merger,
consolidation, or sale of all or substantially all of its Assets, (b) Buyer may
assign all of its rights and obligations hereunder to an Affiliate and (c)
Diginet and Buyer may assign all or any portion of its rights hereunder as

<PAGE>

agreements set forth in Section 12 also shall be for the benefit of, and
enforceable by, Buyer Indemnified Persons, Seller Indemnified Persons and their
respective successors, heirs, executors, administrators, legal representatives
or permitted assigns.

          If any provision of this Agreement or any other Agreement or document
given pursuant or in connection with this Agreement shall be invalid or
unenforceable in any respect, such part shall be ineffective to the extent of
such invalidity or unenforceability only, without in any way affecting the
remaining parts of such provision or the remaining provisions of this Agreement.

    14.12. Section Headings Construction; Gender

           The headings of sections and subsections in this Agreement are

hereto acknowledge that all parties participated equally in the drafting and
negotiation of this Agreement and were represented by counsel of their own

                                                                       ---------

     This outline briefly summarizes the relevant scope of the United States
("U.S.") Foreign Corrupt Practices Act ("FCPA") of 1977, as amended in 1988, and
related regulations; it is for informational purposes only and is not intended
as legal guidance.

    1.  General
        -------

        The FCPA consists basically of a prohibition against U.S. persons
engaging in bribery of foreign officials either directly or indirectly (through
the nationals or entities of other countries).  It is a violation of the FCPA if
a U.S. company or individual corruptly and knowingly takes steps to offer, pay,
give or transfer anything of value to a foreign official, political party,
official of a foreign political party or candidate for foreign political office,
in order to influence any action in the person's official capacity, or to induce
the official to use his influence or to violate his lawful duty, so that the
U.S. firm or individual may obtain or retain business.  This same prohibition
applies to the use of any intermediary who offers or pays such amounts to any of
the foregoing people.  Further, one cannot avoid "knowledge" (and application of
the statue) by deliberately disregarding facts.  Finally, even if a "sensitive"
or "facilitating" payment does not violate the FCPA, it still may result in
violation of other U.S. federal or state laws or laws of foreign countries in
which the company is operating, such as currency restrictions.

    2.  Exceptions and Exclusions.
        -------------------------
        (a)  "Grease" payments.
              ----------------

        It is not prohibited under the FCPA to make any "facilitating" or
"expediting" payment, the purpose of which is simply to expedite or to secure
the performance of a "routine governmental action".  Therefore, a so-called
"grease" payment may be made to a foreign official of any status, but only if it
is for "routine governmental action", defined to mean that which is "ordinarily
and commonly performed without the exercise of discretion."  This grease payment
exclusion does not exempt payments for governmental actions that are for the
functional equivalent of the award or retention of business.

        (b)  Legality under local written law.
             --------------------------------
        It is a defense under the FCPA to make payments which are "lawful
under the written laws and regulations" of the local country.

        (c)  Reasonable and bona fide expenditures.
             -------------------------------------

        It is also a defense under the FCPA to make payments that are directly
related to the promotion, demonstration, etc. of products or services, or the

                                       59
<PAGE>

execution of an existing contract with a foreign government (such as for travel
and lodging expenses).

    3.  Penalties.
        ---------

        The maximum fine for a U.S. corporation is two million dollars and one
hundred thousand dollars for individuals found to have violated the statute.  If
criminal charges are pursued, the possibility for imprisonment is for a period
up to five years.  Additionally, a civil penalty of ten thousand dollars per
violation may be imposed on corporations and individuals by the Department of
Justice.  Further, an individual corporate employee may be convicted even if the
U.S. corporation has not been found to have violated the FCPA.  Finally, a
violation of the antibribery provisions of the FCPA may result in a U.S.
government-wide suspension or debarment from participation in American funded
programs.

<PAGE>

  (a) Requested Registration.  At any time after the earlier to occur of (i)
      ----------------------
April 16, 2003, and (ii) the Company's initial public offering of equity
securities (such an offering, an "Initial Public Offering"), upon written
request by the Initiating Holders to the Company that the Company effect a
registration under the Securities Act (a "Requested Registration"), the Company
shall use its diligent efforts to file a registration statement on Form S-1 or
any similar long-form registration statement (each, a "Long-Form Registration
Statement") (x) with respect to the first such Long-Form Registration Statement
within ninety (90) days after receipt of such request by such Initiating Holders
and (y) with respect to each successive Long-Form Registration Statement, within
sixty (60) days after receipt of such request by such Initiating Holders, in
each case in order to effect the registration under the Securities Act of the
Registrable Securities (other than Founder Stock) that the Company has been so
requested to register or to file a registration statement on Commission Form S-2
or Form S-3 or any successor or similar short-form registration statement (each,
a "Short-Form Registration Statement") within forty-five (45) days after receipt
of such request if the Company is qualified to file a Short-Form Registration
Statement; provided, however, that the Company shall not be obligated to file a
           --------  -------
Requested Registration on a Short-Form Registration Statement (a "Short-Form
Registration") pursuant to this Section 2(a) unless the anticipated gross
aggregate offering price of the Registrable Securities to be sold pursuant
thereto is at least two million dollars ($2,000,000) in the aggregate; provided,
                                                                       --------
further, however, that in the event the Company has not completed an Initial
- -------  -------
Public Offering, the Company shall not be obligated to file a Requested
Registration on a Long-Form Registration Statement (a "Long-Form Registration")
pursuant to this Section 2(a) unless at least eighty million dollars
($80,000,000) in aggregate principal amount of the Registrable Securities (as
measured by the aggregate gross offering price thereof as reflected in the
registration statement with respect thereto), after giving effect to such
registration, would be registered under the Securities Act; provided, further,
                                                            --------  -------
however, that if the Company has previously completed an Initial Public Offering
- -------
the Company shall not be obligated to file a Long-Form Registration unless the
anticipated aggregate gross offering price with respect thereto would equal or
exceed thirty million dollars ($30,000,000).  The Company must file an unlimited
number of Short-Form Registrations pursuant to this Section 2(a) subject to the
requirement that any such Short-Form Registration meets the two million dollar
($2,000,000) aggregate offering threshold referenced above and otherwise
satisfies the conditions or requirements applicable thereto.  In no event shall
the Company be obligated hereunder to file more than six (6) Long-Form
Registrations in the aggregate or more than two (2) Long-Form Registrations
requested by any Investor and the affiliates thereof.  Subject to Section 2(f),
the Company may include in such Requested Registration other securities of the
Company for sale, for the Company's account or for the account of any other
person, if and to the extent that the managing underwriter determines that the
inclusion of such additional shares will not interfere with the orderly sale of
the Registrable Securities subject to such Requested Registration at a price
range acceptable to the Majority Initiating Holders.  Upon filing of a Long-Form
Registration Statement or a Short-Form Registration Statement, as the case may
be, the Company shall thereafter use its diligent efforts to cause such
registration statement to be declared effective under the Securities Act as
promptly as possible.

  (b) Incidental Registration.  If the Company for itself or any of its security
      -----------------------
holders shall at any time or times after the date hereof determine to register
under the Securities Act any shares of its capital stock or other securities
(other than (i) the registration of an offer, sale or other disposition of
securities solely to employees of, or other persons providing services to, the

                                      -5-
<PAGE>

Company or any subsidiary pursuant to an employee or similar benefit plan or
(ii) relating to a merger, acquisition or other transaction of the type
described in Rule 145 under the Securities Act or a comparable or successor
rule, registered on Form S-4 or similar or successor forms), on each such
occasion the Company will notify each Holder of such determination at least ten
(10) days after receipt of any Requested Registration or, in the case that the
Company determines to register for its own account any shares of its capital
stock, at least thirty (30) days prior to the filing of the registration
statement applicable thereto, and upon the request of any Holder given in
writing within twenty (20) days after the receipt of such notice, subject to
Section 2(f), the Company will use its diligent efforts as soon as practicable
thereafter to cause any of the Registrable Securities specified by any such
Holder to be included in such registration statement to the extent such
registration is permissible under the Securities Act and subject to the
conditions of the Securities Act (an "Incidental Registration").

  (c) Registration Statement Form.  The Company shall, if permitted by law,
      ---------------------------
effect any registration requested under this Section 2 by the filing of a Short-
Form Registration Statement and shall use its diligent efforts to take any
action reasonably necessary to maintain its eligibility to utilize a Short-Form
Registration Statement to permit resales as requested by the Holders with
respect to "Transactions Involving Secondary Offerings" as described in General
Instruction I.B.3 of Commission Form S-3.

  (d) Expenses.  The Company shall pay all Registration Expenses incurred in
      --------
connection with any Incidental Registration and any Requested Registration.

  (e) Effective Registration Statement.  A Requested Registration or an
      --------------------------------
Incidental Registration pursuant to Section 2(a) or Section 2(b), respectively,
shall not be deemed to have been effected unless the registration statement
filed with respect thereto in accordance with the Securities Act has been
declared effective by the Commission.  Notwithstanding the foregoing, a
registration statement will not be deemed to have become effective if (i) after
it has become effective with the Commission, such registration is interfered
with by any stop order, injunction or other order or requirement of the
Commission or other governmental agency or any court proceeding for any reason
other than a misrepresentation or omission by any Holder, or (ii) the conditions
to closing specified in the purchase agreement or underwriting agreement entered
into in connection with such registration are not satisfied, other than solely
by reason of some act or omission by any Holder.

  (f) Priority in  Registration. If a Requested Registration or an Incidental
      -------------------------
Registration is made in connection with an underwritten offering, and the
managing underwriters give written advice to the Initiating Holders or the
Company, as the case may be, that, in their opinion, market conditions dictate
that no more than a specified maximum number of securities (the "Underwriter's
Maximum Number") could successfully be included in such registration, then the
Company and the Holders shall participate in such offering in the following
order of priority:  (A) in the case of a Requested Registration, (i) there shall
be included in such registration that number of Registrable Securities issued
upon conversion of shares of Series A-1 Preferred Stock, Series A-2 Preferred
Stock, Series B-1 Preferred Stock, Series B-2 Preferred Stock (including
Registrable Securities issuable upon conversion of (x) the Series A-2 Preferred
Stock issuable upon conversion of the Series A-2 Warrants and (y) the Series B-1
Preferred Stock issuable upon conversion of the Series B-1 Warrants) and Series
C-1 Preferred Stock that the holders thereof

                                      -6-
<PAGE>

shall have requested to be included in such offering either as an Initiating
Holder or as to an Incidental Registrant and that does not exceed the
Underwriter's Maximum Number; (ii) the Company shall be entitled to include in
such registration that number of securities that it proposes to offer and sell
for its own account to the full extent of the remaining portion of the
Underwriter's Maximum Number; and (iii) to the extent not inconsistent with any
registration rights hereafter granted by the Company to holders of Company
securities, the Founder Holders shall be entitled to include in such
registration that number of shares of Registrable Securities that the Founder
Holders shall have requested to be included in such registration to the full
extent of the remaining portion of the Underwriter's Maximum Number; and (B) in
the case of an Incidental Registration triggered by a proposed registration for
the account of the Company (i) the Company shall be entitled to include in such
registration that number of securities that the Company proposes to offer and
sell for its own account in such registration and that does not exceed the
Underwriter's Maximum Number; (ii) the Company will be obligated and required to
include in such registration that number of shares of Registrable Securities
issued upon the conversion of shares of Series A-1 Preferred Stock, Series A-2
Preferred Stock, Series B-1 Preferred Stock, Series B-2 Preferred Stock
(including Registrable Securities issuable upon conversion of (x) the Series A-2
Preferred Stock issuable upon conversion of the Series A-2 Warrants and (y) the

and Series C-1 Preferred Stock that the holders thereof shall have requested to
be included in such offering as an Incidental Registration to the full extent of
the remaining portion of the Underwriter's Maximum Number; and (iii) to the
extent not inconsistent with any registration rights hereafter granted by the
Company to holders of the Company's securities, the Company will be obligated
and required to include in such registration that number of shares of Founder
Stock requested to be included in such offering by the Founder Holders along
with other securities of the Company that shall have been requested by other
Persons having registration rights pursuant to one or more other registration
rights agreements with the Company. If the number of shares of Registrable
Securities requested to be included in an underwritten offering exceeds the then
remaining portion of the Underwriter's Maximum Number as provided in clauses (A)
and (B) of this Section 2(f), as the case may be, then the Holders whose
aggregate request so exceeds the then remaining portion of the Underwriter's
Maximum Number and who are then entitled to include shares up to such
Underwriter's Maximum Number in accordance with the priority established in
clauses (A) and (B) of this Section 2(f) may include shares of Registrable
Securities in such underwritten offering pro rata in accordance with the
                                         --- ----
relative number of shares originally requested to be included in such offering
by such Holders in the writing delivered in accordance with Section 2(a) or
Section 2(b), as the case may be.

  (g) Notwithstanding anything in this Section 2 to the contrary, the Company
shall have the right to delay any registration of Registrable Securities
requested pursuant to Section 2(a) for up to ninety (90) days if such
registration would, in the good faith judgment of the Company's Board of
Directors, substantially interfere with any material transaction being
considered at the time of receipt of the request from the Holders.

  (h) Notwithstanding anything in this Agreement to the contrary, the Company
shall not be obligated to take any action to effect registration, qualification
or compliance with respect to its Registrable Securities:

                                      -7-

Securities Act;

      (ii)   that would require it to qualify generally to do business in any
jurisdiction which it is not already so qualified;

Company, provided that the Company is actively employing in good faith
         --------

                                      -11-
<PAGE>

underwriters under such underwriting agreement be conditions precedent to the
obligations of such Holder. No Holder participating in any such underwritten
registration shall be required to make any representations or warranties to or
agreements with the Company or the underwriters other than representations,
warranties or agreements regarding such Holder and its intended method of
distribution and any other representation required by law.

  (b) Selection of Underwriters.  If a Requested Registration involves an
      -------------------------
underwritten offering, then the Company shall select the underwriter from among
underwriting firms of national reputation, subject to the consent of the
Majority Initiating Holders, which consent shall not be unreasonably withheld.

  (c) Holdback Agreements.  (i)  Each Holder agrees, if so requested by the
      -------------------
managing underwriter in each underwritten registration of the Company's capital
stock or other securities described in Section 2(a) and Section 2(b), to sign an
agreement not to effect (except as part of such underwritten registration in
accordance with the provisions hereof) any sale, distribution, short sale, loan,
grant of options for the purchase of, or otherwise dispose of, any Registrable
Securities for such period as such underwriter requests, such period in no event
to commence earlier than seven (7) days prior to, or to end more than (i) 180
days after an Initial Public Offering or (ii) 90 days after the effective date
of any other registration, provided that each Holder is treated on an equal
basis in being required to comply with such underwriter's request.

      (ii) The Company agrees, if so requested by the managing underwriter in
each underwritten registration of the Company's capital stock or other
securities described in Section 2(a), to sign an agreement not to effect (except
as part of such underwritten registration in accordance with the provisions
hereof) any sale, distribution, short sale, loan, grant of options for the
purchase of, or otherwise dispose of, any Registrable Securities for such period
as such underwriter requests, such period in no event to commence earlier than
seven (7) days prior to, or to end more than 180 days after, the effective date
of such Requested Registration.

  5.  Preparation, Reasonable Investigation.
      -------------------------------------

  In connection with the preparation and filing of each registration statement
under the Securities Act, the Company will give the Holders of Registrable
Securities to be sold under such registration statement, the underwriters, if
any, and their respective counsel and accountants, advance draft copies of such
registration statement and each prospectus included therein or filed with the
Commission at least 5 business days prior to the filing thereof with the
Commission, and any amendments and supplements thereto promptly as they become
available, and will give each of them such access to its books and records and
such opportunities to discuss the business of the Company with its officers and
the independent public accountants who have certified its financial statements
as shall be necessary, in the reasonable opinion of such Holders and such
underwriters' respective counsel, to conduct a reasonable investigation within
the meaning of the Securities Act.

  6.  Controlling Stockholders Rights.
      -------------------------------

      If any registration statement prepared in connection with a Requested
Registration or an Incidental Registration refers to any holder by name or
otherwise as the holder of any securities

                                      -12-
<PAGE>

of the Company and if, in such holder's sole and exclusive judgment, such holder
is or might be deemed to be a controlling person of the Company, such holder
shall have the right to require (i) the insertion therein of language, in form
and substance satisfactory to such holder and presented to the Company in
writing and reasonably acceptable to the Company, 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 financial requirements of the Company, or (ii) in the event that
such reference to such holder by name or otherwise is not required by the
Securities Act or any similar Federal statute then in force, the deletion of the
reference to such holder to the extent not required thereby.

  7.  Withdrawal of Requested Registration.
      ------------------------------------

      A Requested Registration may only be withdrawn upon the request of the
Majority Initiating Holders with respect to such Requested Registration.

  8.  Indemnification and Contribution.
      --------------------------------

  (a) Indemnification by the Company.  In the event of any registration under
      ------------------------------
the Securities Act pursuant to Section 2 of any Registrable Securities, the
Company shall indemnify and hold harmless each Holder of Registrable Securities
to be sold pursuant to such registration statement, its directors, officers and
each Person, if any, who controls any Holder within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act, each other
Person who participates as an underwriter or a Qualified Independent
Underwriter, if any, in the offering or sale of such securities (if so required
by such underwriter as a condition to including the Registrable Securities of
the Holders in such registration), and each Person, if any, who controls any
such underwriter or Qualified Independent Underwriter, within the meaning of
either Section 15 of the Securities Act or Section 20 of the Exchange Act
(collectively, the "Indemnified Parties"), from and against any losses, claims,
damages or liabilities, joint or several, arising out of, based upon or caused
by any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which such securities were
registered under the Securities Act, or any preliminary prospectus, final
prospectus or summary prospectus contained therein or any document incorporated
therein by reference, or any amendment or supplement thereto, or arising out of,
based upon or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein in light of the circumstances in which they were made not misleading or
arise out of any violation by the Company of any rule or regulation promulgated
under the Securities Act or state securities law applicable to the Company and
relating to action or inaction required of the Company in connection with any
such registration, except (i) with respect to a Holder insofar as such losses,
claims, damages or liabilities are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information relating
to such Holder furnished to the Company in writing by such Holder specifically
for use therein or (ii) with respect to an Underwriter insofar as such losses,
claims, damages or liabilities are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information relating
to such underwriter or Qualified Independent Underwriter furnished to the
Company in writing by such underwriter or Qualified Independent Underwriter
specifically for use therein, and the Company will reimburse the Indemnified
Parties for any legal or any other expenses reasonably

                                      -13-
<PAGE>

incurred by them in connection with investigating or defending any such loss,
claim, liability, action or proceeding; provided, that the foregoing indemnity
                                        --------
agreement with respect to any preliminary prospectus shall not inure to the
benefit of any underwriter from whom the person asserting any such losses,
claims, damages or liabilities purchased Registrable Securities or any person
controlling such underwriter, if a copy of the Final Prospectus (as then amended
or supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such underwriter
to such person, if required by law so to have been delivered, at or prior to the
written confirmation of the sale of the Registrable Securities to such person.

  (b) Indemnification by the Holders.  The Company may require, as a condition
      ------------------------------
to including any Registrable Securities of any person or entity in any
registration statement filed pursuant to Section 2, that the Company shall have
received an undertaking reasonably satisfactory to it from such person or entity
to indemnify and hold harmless (in the same manner and to the same extent as set
forth in subdivision (a) of this Section 8) the Company, each director of the
Company, each officer who has signed the registration statement and each other
Person, if any, who controls the Company within the meaning of either Section 15
of the Securities Act or Section 20 of the Exchange Act, with respect to any
statement or alleged statement in or omission or alleged omission from such
registration statement or any preliminary prospectus, final prospectus or
summary prospectus contained therein, or any amendment or supplement thereto,
if, and only if, such statement or alleged statement or omission or alleged
omission was made in reliance upon and in conformity with information furnished
in writing to the Company by such person or entity specifically for use therein.
The obligation of any Holder hereunder is a separate obligation of each Holder
and is not a joint obligation with any other holder of Registrable Securities
and shall be limited to an amount equal to the net proceeds received by such
Holder from the sale of Registrable Securities in the offering covered by such
registration, unless such liability arises out of or is based upon such Holder's
willful misconduct.

  (c) Indemnification Procedures.  Promptly after receipt by an Indemnified
      --------------------------
Party of notice of the commencement of any action or proceeding involving a
claim referred to in the preceding subdivisions of this Section 8, such
Indemnified Party shall, if a claim in respect thereof is to be made against a
party required to provide indemnification (an "Indemnifying Party"), give
written notice to the latter of the commencement of such action; provided,
                                                                 --------
however, that the failure of any Indemnified Party to give notice as provided
- -------
herein shall not relieve the Indemnifying Party of its obligation under the
preceding subdivisions of this Section 8, except to the extent that the
Indemnifying Party is actually prejudiced by such failure to give notice.  In
case any such action is brought against an Indemnified Party, the Indemnifying
Party shall be entitled to participate in and to assume the defense thereof,
jointly with any other Indemnifying Party similarly notified to the extent that
it may wish, with counsel reasonably satisfactory to such Indemnified Party, and
after notice from the Indemnifying Party to such Indemnified Party of its
election so to assume the defense thereof, the Indemnifying Party shall not be
liable to such Indemnified Party for any legal or other expenses subsequently
incurred by the latter in connection with the defense thereof other than
reasonable costs of investigation. In any such proceeding, any Indemnified Party
shall have the right to retain its own counsel, but the fees and expenses of
such counsel shall be at the expense of such Indemnified Party unless (i) the
Indemnifying Party and the Indemnified Party shall have mutually agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties)

                                      -14-
<PAGE>

include both the Indemnifying Party and the Indemnified Party and representation
of both parties by the same counsel would be, in the reasonable judgment of the
Indemnified Party, inappropriate due to actual differing interests between them.
It is understood that the Indemnifying Party shall not, in respect of the legal
expenses of any Indemnified Party in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for (i) the fees and expenses of
more than one separate firm (in addition to any local counsel) for all
underwriters and all persons, if any, who control any underwriter within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act, (ii) the fees and expenses of more than one separate firm (in addition to
any local counsel) for the Company, its directors, its officers who sign the
Registration Statement and each Person, if any, who controls the Company within
the meaning of either such Section and (iii) the fees and expenses of more than
one separate firm (in addition to any local counsel) for any Holders and all
Persons, if any, who control any Holder within the meaning of either such
Section. The Indemnifying Party shall not be liable for any settlement of any
proceeding effected without its written consent, which consent will not be
unreasonably withheld, but if settled with such consent or if there be a final
judgment for the plaintiff, the Indemnifying Party agrees to indemnify the
Indemnified Party from and against any loss or liability by reason of such
settlement or judgment. No Indemnifying Party shall, without the consent of the
Indemnified Party, effect the settlement or compromise of, or consent to entry
of any judgment or enter into any settlement with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the Indemnified Party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (A) includes an unconditional release of the Indemnified Party from all
liability arising out of such action or claim and (B) 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) Other Indemnification.  Indemnification similar to that specified in the
      ---------------------
preceding subdivisions of this Section 8 (with appropriate modifications) shall
be given by the Company and each Holder of Registrable Securities included in
any registration statement with respect to any required registration or other
qualification of securities under any Federal or state law or regulation of any
governmental authority, other than the Securities Act.

  (e) Indemnification Payment.  The indemnification required by this Section 8
      -----------------------
shall be made by periodic payments of the amount thereof during the course of
the investigation or defense, as and when bills are received or expense, loss,
damage or liability is incurred.

  (f) Survival of Obligations.  The obligations of the Company and of the
      -----------------------
Holders under this Section 8 shall survive the completion of any offering of
Registrable Securities in accordance with this Agreement and will remain in full
force and effect regardless of any investigation made by or on behalf of the
indemnified party or any officer, director or controlling Person of such
indemnified party.

  (g) Contribution.  If the indemnification provided for in this Section 8 is
      ------------
unavailable or insufficient to hold harmless an Indemnified Party, then each
Indemnifying Party shall contribute to the amount paid or payable to such
Indemnified Party as a result of the losses, claims, damages or liabilities
referred to in this Section 8 an amount or additional amount, as the case may
be, in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party

                                      -15-
<PAGE>

or Indemnifying Parties on the one hand and the Indemnified Party on the other
in connection with the statements or omissions which resulted in such losses,
claims, demands or liabilities as well as any other relevant equitable
considerations. With respect to contribution required pursuant to this Section
8(g), the relative fault 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 Indemnifying Parties on the one hand or
the Indemnified Party on the other, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such untrue
statement or omission. The amount paid to an Indemnified Party as a result of
the losses, claims, damages or liabilities referred to in the first sentence of
this Section 8(g) shall be deemed to include any legal or other expenses
reasonably incurred by such Indemnified Party in connection with investigating
or defending any action or claim which is the subject of this Section 8.
Notwithstanding the provisions of this Section 8(g), an indemnified holder of
Registrable Securities shall not be required to contribute any amount in excess
of the amount by which the net proceeds to such holder of Registrable Securities
from the sale thereof exceed the amount of damages which such indemnified holder
has otherwise been required to pay pursuant to Section 8(a) or Section 8(b), as
applicable, by reason of any 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 Securities Act shall be entitled to contribution
from any Person who was not guilty of such fraudulent misrepresentation.

  If indemnification is available under Section 8(a) or Section 8(b), an
indemnifying party shall indemnify an indemnified party to the full extent
provided in Section 8(a) or Section 8(b), as applicable, without regard to the
equitable considerations provided for in the immediately preceding paragraph.

  9.  Covenants Relating to Rule 144.
      ------------------------------

  With a view to making available the benefits of certain rules and regulations
of the Commission which may at any time permit the sale of securities of the
Company to the public without registration after such time as a public market
exists for the Common Stock of the Company, the Company agrees:

  (a) to make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times after
the effective date of the first registration under the Securities Act filed by
the Company for an offering of its securities to the general public;

  (b) to use its diligent efforts to then file with the Commission 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 a Holder owns any Registrable Securities, to furnish to the
Holder forthwith upon request (i) a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144 (at any time after
90 days after 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

                                      -16-
<PAGE>

reporting requirements) or that it qualifies as a registrant whose securities
may be resold pursuant to a Short-Form Registration Statement (at any time after
it so qualifies), (ii) a copy of the most recent annual or quarterly report of
the Company filed with the Commission and (iii) such other reports and documents
of the Company as a Holder may reasonably request in availing itself of any rule
or regulation of the Commission allowing a Holder to sell any such securities
without registration.

  10.  Other Registration Rights.
       -------------------------

  The Company represents and warrants that it has not granted any registration
rights to any Person. The Company shall not grant to any Person any registration
rights more favorable than or inconsistent with any of those contained herein,
so long as any of the registration rights under this Agreement remain in effect.

  11.  Miscellaneous.
       -------------

  (a) Specific Performance.  The parties hereto acknowledge that there may be no
      --------------------
adequate remedy at law if any party fails to perform any of its obligations
hereunder and that each party may be irreparably harmed by any such failure, and
accordingly agree that each party, in addition to any other remedy to which it
may be entitled at law or in equity, shall be entitled to compel specific
performance of the obligations of any other party under this Agreement in
accordance with the terms and conditions of this Agreement.

  (c) Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
      -------------
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO ANY
CONFLICTS OR CHOICE OF LAWS PROVISIONS THAT WOULD CAUSE THE APPLICATION OF THE
DOMESTIC SUBSTANTIVE LAWS OF ANY OTHER JURISDICTION).

  (d) Headings.  The descriptive headings of the several sections and paragraphs
      --------
of this Agreement are inserted for convenience only and do not constitute a part
of this Agreement and shall not affect in any way the meaning or interpretation
of this Agreement.

  (e) Entire Agreement; Amendments.  This Agreement and the other writings
      ----------------------------
referred to herein or delivered pursuant hereto which form a part hereof contain
the entire understanding of the parties with respect to its subject matter.
This Agreement terminates, restates and supersedes all prior agreements and
understandings between the parties with respect to its subject matter, including
the Original Registration Rights Agreement.  This Agreement may be amended and
the observance of any term of this Agreement may be waived (either generally or
in a particular instance and either retroactively or prospectively) only by a
written instrument duly executed by the Company and the Holders of not less than
85% of the Registrable Securities.  Each Holder of any Registrable Securities at
the time or thereafter outstanding shall be bound by an amendment

                                      -18-
<PAGE>

or waiver authorized by this Section 11(e), whether or not any such Registrable
Securities shall have been marked to indicate such consent.

  (f) Assignability.  This Agreement and all of the provisions hereof will be
      -------------
assigned, without the consent of the Company, by any Holder to, and shall inure
to the benefit of, any purchaser, transferee or assignee of any Registrable
Security, unless the Holder specifies otherwise in connection with particular
transfers of Registrable Securities.  However, the Company shall not be required
to recognize any such purchaser, transferee or assignee as a Holder under this
Agreement unless and until either (i) such person becomes the holder of record
of Registrable Securities or (ii) the Company receives written notice of such
purchase, transfer or assignment.

  (g) Counterparts.  This Agreement may be executed in two or more counterparts,
      ------------
each of which shall be deemed an original, but all of which together shall
constitute one and the same instrument.

  (h) Adjustments Affecting Registrable Securities.  Unless failure to do so
      --------------------------------------------
would have a material adverse effect on the Company or its subsidiaries, the
Company will not take any action, or permit any change to occur, with respect to
its securities which would materially and adversely affect the ability of the
holders of Registrable Securities to include such Registrable Securities in a
registration undertaken pursuant to this Agreement or which would materially and
adversely affect the marketability of such Registrable Securities in any such
registration (including, without limitation, effecting a stock split or a
combination of shares).

                             EMPLOYMENT AGREEMENT
                             ---------------------

        THIS EMPLOYMENT AGREEMENT, dated as of April 16, 1999 (this
"Agreement"), by and between Diginet Americas, Inc., a Delaware corporation (the
 ---------
"Company"), and David Schmieg (the "Employee").
 -------        -------------       --------

        WHEREAS, the Employee represents that he possesses skills, experience
and knowledge that are of value to the Company; and

        WHEREAS, the Company desires to enlist the services and employment of
the Employee on behalf of the Company and the Employee is willing to render such
services on the terms and conditions set forth herein.

        NOW, THEREFORE, in consideration of the mutual covenants contained
herein, the parties hereto agree as follows:

        1.   Employment Term.  Except for earlier termination as provided for in
             ---------------
Section 7 hereof, the Company hereby agrees to employ the Employee, and the
Employee hereby agrees to be employed by the Company, subject to the terms and
provisions of this Agreement, for the period commencing on the "Effective Date"
                                                                --------------
(as defined in Section 21 below) and ending on the third anniversary of such
date (the "Initial Term"), provided, however, that upon the expiration of the
           ------------    --------  -------
Initial Term, the term of employment shall be automatically extended for a
period of two years, unless either the Company or the Employee shall have given
written notice to the other at least ninety (90) days prior the expiration of
the Initial Term that the term of employment shall not be so extended (the
Initial Period and any subsequent period of extension of employment, the
"Employment Term").
 ---------------

        2.  Duties.  During the Employment Term the Employee shall serve as
            ------
President and Chief Executive Officer of the Company, and (for so long as the
Company is not subject to the reporting requirements of Sections 13(a) and 15(d)
of the Securities Exchange Act of 1934) the Employee shall serve as a member of
the Board of Directors of the Company (the "Board"). The Employee shall perform
                                            -----
such senior executive duties, services and responsibilities on behalf of the
Company and its subsidiaries as may be determined from time to time by the
Board. In performing such duties hereunder, the Employee will report directly to
the Board.

        The Employee shall devote his full business time, attention and skill to
the performance of such duties, services and responsibilities, and will use his
best efforts to promote the interests of the Company. The Employee will not,
without the approval of the Board (a) engage in any corporate, civic or
charitable activity which would interfere with the performance of his duties as
an employee of the Company, is in violation of written Company policies, is in
violation of applicable law, or would create a conflict of
<PAGE>

interest with respect to the Employee's obligation as an employee of the
Company, or (b) deliver lectures, fulfill speaking engagements or teach at
educational institutions.

        3.  Compensation.  In full consideration of the performance by the
            ------------

services as an officer, director, employee or member of any committee of any
subsidiary or affiliate of the Company, or otherwise on behalf of the Company),
the Employee shall receive a base salary (the "Base Salary") at an annual rate
                                               -----------
of $400,000 per year, payable semimonthly. During the Employment Term, the
Employee will be eligible to receive annual increases in the Base Salary as
determined in the sole discretion of the Board. The Employee shall be solely
responsible for taxes imposed on the Employee by reason of any compensation and
benefits provided under this Agreement and all such compensation and benefits
shall be subject to applicable withholding taxes.

        4.  Disability.  If the Employee is unable, as reasonably determined by
            ----------
the Board, to perform his duties, services and responsibilities hereunder by
reason of a physical or mental infirmity for a total of ninety (90) calendar
days in any twelve-month period during the Employment Term ("Disability"), the
                                                             ----------
Company shall not be obligated to pay the Employee any Base Salary for any
period of absence in excess of such ninety (90) calendar days and, in any case,
shall be entitled to terminate the Employee's employment hereunder in accordance
with Section 7.

        5.  Incentive Plans/Benefits.  In addition to the payments of the Base
            ------------------------
Salary described above, during the Employment Term the Employee shall be: (i)
eligible to receive a performance based annual bonus equal to 100% of the
Employee's Base Salary upon attainment of 100% target performance, (ii) entitled
to reimbursement for reasonable membership dues in professional organizations,
and (iii) entitled to participate in employee benefit plans, policies, programs
and arrangements, as may be amended from time to time, that are provided
generally to senior executives of the Company to the extent the Employee meets
the eligibility requirements for any such plan, policy, program or arrangement.

        6.  Vacations.  During the Employment Term the Employee shall be
            ---------
entitled to the number of paid vacation days in each calendar year determined by
the Company in accordance with the Company's policies in effect from time to
time.

        7.  Termination.  The Employee's employment with the Company and the
            -----------
Employment Term shall terminate upon the expiration of the Employment Term or
upon the earlier occurrence of any of the following events (the date of
termination, the "Termination Date"):
                  ----------------

        (a) The death of the Employee ("Death").

business of the Company, (ii) the Employee's repeated, reckless misconduct
injurious to the Company and failure to cure such action within ten (10) days
after written demand for substantial improvement in performance with reasonable
detail delivered to the Employee by the Board, or (iii) the Employee's material
breach of this Agreement. For all purposes of the Employee's employment by the
Company, if the Employee's employment is terminated for Cause, the effective
date of such termination shall be the date of delivery of the Cause Notice.

Reason" shall mean: (i) any reduction in Base Salary, (ii) any material
- ------
diminution in the Employee's position, duties or responsibilities, or (iii) any

corporate headquarters.

        In the event of termination of the Employee's employment, for whatever
reason (other than Death), the Employee agrees to cooperate with the Company,
its subsidiaries and affiliates and to be reasonably available to the Company,
its subsidiaries and affiliates with respect to continuing and/or future matters
arising out of the Employee's employment hereunder or any other relationship
with the Company, its subsidiaries or affiliates, whether such matters are

business expenses incurred by the Employee in connection with the Employee's
employment on behalf of the Company on or prior to the Termination Date but not
previously paid to the Employee (the "Accrued Compensation").
                                      --------------------

        (b) If the Employee's employment with the Company terminates pursuant to
Subsection (e) or (f) of Section 7 hereof, for a period of one year following

                                     - 3 -

the Termination Date, but only for so long as the Employee is in compliance with
Section 10 hereof, the Company shall continue to pay the Employee the Base
Salary in accordance with the normal payroll practices of the Company with
respect to such Base Salary, and shall continue to provide the Employee with
medical coverage substantially comparable to that provided generally to senior

        (c)     If the Employee's employment with the Company terminates
pursuant to Subsections (a) or (d) of Section 7 hereof, for a period of six
months following the Termination Date, but only for so long as the Employee is
in compliance with Section 10 hereof, the Company shall continue to pay the
Employee the Base Salary in accordance with the normal payroll practices of the
Company with respect to such Base Salary, and shall continue to provide the
Employee with medical coverage substantially comparable to that provided
generally to senior officers of the Company.

       (d)      Vesting of Options. In the event the Employee's employment

        (e)     All options to acquire shares of Common Stock granted to the
Employee on March 10, 1999 (the "Grant Date") shall be subject to all of the

options shall vest and no longer be forfeitable according to the following
schedule:  10% of the shares of Common Stock shall be vested on the Grant Date,
15% of the shares of Common Stock shall vest on March 10, 2000, and 1/48 of the
shares of Common Stock shall vest on the 10th of each month thereafter, in each
case, if the Employee is employed by the Company on such date.

             -----------------------
in the Employee's position with the Company, the Employee will be exposed to and
will receive information relating to the confidential affairs of the Company,
its subsidiaries and affiliates, including but not limited to technical

Employment Term, and thereafter during the "Non-competition Term" (as defined
                                            --------------------
below), directly or indirectly, own, manage, operate, join, control, be employed
by, or participate in the ownership, management, operation or control of, or be
connected in any manner with, including but not limited to holding any position
as a shareholder, director, officer, consultant, independent contractor,

                                        ---------------------
below); provided that in no event shall ownership of less than 1% of the
        --------
outstanding equity securities of any issuer whose securities are registered

prohibited by this Subsection (b) of this Section 10. For purposes of this
paragraph, the term "Restricted Enterprise" shall mean any person, corporation,
                     ---------------------
partnership or other entity that is engaged, directly or indirectly, in
providing local data and/or voice telecommunications services in Latin America.
Following termination of the Employment Term, upon request of the Company, the
Employee shall notify the Company of the Employee's then current employment
status. For purposes of this Agreement, the "Non-competition Term" shall mean
                                             --------------------
the period beginning on the Termination Date and ending on the second
anniversary of such date. Any material breach of the terms of this paragraph
shall be considered Cause.

        (c) Non-solicitation. During the Non-competition Term, the Employee
            ----------------
shall not, and shall not cause any other person to, interfere with or harm, or
attempt to interfere with or harm, the relationship of the Company, any of its
subsidiaries or affiliates with, or endeavor to entice away from the Company,
any of its subsidiaries or affiliates, or hire, any person who at any time
during the Employment Term was an employee or customer of the Company, any of
its subsidiaries or affiliates, or otherwise had a material business
relationship with the Company, any of its subsidiaries or affiliates.

        (d) Remedies. The Employee agrees that any breach of the terms of this
            --------
Section 10 would result in irreparable injury and damage to the Company, its
subsidiaries and/or its affiliates for which the Company, its subsidiaries
and/or its affiliates would have no adequate remedy at law; the Employee
therefore also agrees that in the event of said breach or any threat of breach,
the Company, its subsidiaries and/or its affiliates, as applicable, shall be
entitled to an immediate injunction and restraining order to prevent such breach
and/or threatened breach and/or continued breach by the Employee and/or any and
all persons and/or entities acting for and/or with the Employee, without having
to prove damages, in addition to any other remedies to which the Company, its
subsidiaries and/or its affiliates may be entitled at law or in equity. The
terms of this paragraph shall not prevent the Company, its subsidiaries and/or
its affiliates from pursuing any other available remedies for any breach or
threatened breach hereof, including but not limited to the recover of damages
from the Employee. The Employee and the Company further agree that the
provisions of the covenants contained in this Section 10 are reasonable and
necessary to protect the businesses of the Company, its subsidiaries and
affiliates because of the Employee's access to Confidential Information and his
material participation in the operation of such businesses. Should a court,
arbitrator or other similar authority

                                     - 6 -
<PAGE>

determine, however, that any provision of the covenants contained in this
Section 10 are not reasonable or valid, either in period of time, geographical
area, or otherwise, the parties hereto agree that such covenants should be
interpreted and enforced to the maximum extent to which such court or arbitrator
deems reasonable or valid.

        The existence of any claim or cause of action by the Employee against
the Company and/or its subsidiaries and/or its affiliates, whether predicated on
this Agreement or otherwise, shall not constitute a defense to the enforcement
by the Company or the covenants contained in this Section 10.

        11.     Non-Waiver of Rights. The failure to enforce at any time the
                --------------------
provisions of this Agreement or to require at any time performance by any other
party of any of the provisions hereof shall in no way be construed to be a
waiver of such provisions or to affect either the validity of this Agreement or
any part hereof, or the right of any party to enforce each and every provision
in accordance with its terms.

        12.     Notices.  Every notice relating to this Agreement shall be in
                -------
writing and shall be given by personal delivery or by registered or certified
mail, postage prepaid, return receipt requested.

        13.     Binding Effect/Assignment.  This Agreement shall inure to the
                -------------------------
benefit of and be binding upon the parties hereto and their respective heirs,
executors, personal representatives, estates, successors (including, without
limitations, by way of merger) and assigns.  Notwithstanding the provisions of
the immediately preceding sentence, the Employee shall not assign all or any
portion of this Agreement without the prior written consent of the Company.

        14.     Entire Agreement.  This Agreement and the Option Agreement,
                ----------------
dated April 16, 1999, between the Employee and the Company, sets forth the
entire understanding of the parties hereto with respect to the subject matter
hereof and supersedes all prior agreements, written or oral, between them as to
such subject matter, including the Employment Agreement between the Employee and
the Company executed by the Employee on January 30, 1999, which shall be null
and void.  This Agreement may not be amended, nor may any provision hereof be
modified or waived, except by an instrument in writing duly signed by the party
to be charges.

        15.     Severability.  If any provision of this Agreement, or any
                ------------
application thereof to any circumstances, is invalid, in whole or in part, such
provision or application shall to that extent be severable and shall not affect
other provisions or applications of this Agreement.

        16.     Governing Law.  This Agreement shall be governed by and
                -------------
construed in accordance with the internal laws of the State of New York, without
reference to the principles of conflict of laws.

                                     - 7 -

        17.  Arbitration.  The Employee agrees that, at the Company's election
             -----------
(which election may be made on the Company's sole and absolute discretion at any
time prior to the commencement of a judicial proceeding by the Company or, in
the event instituted by the Employee, at any time prior to the last day to
answer and/or respond to a summons and/or complaint made by the Employee), any
dispute of any kind, nature or description between the parties hereto in respect
of, relating to, or arising out of this agreement, the Employee's employment by
the Company, and/or the termination thereof, shall be submitted to binding
arbitration in the District of Columbia before the American Arbitration
Association.

        18.  Modifications and Waivers.  No provision of this Agreement may be
             -------------------------
modified, altered or amended except by an instrument in writing executed by the
parties hereto.  No waiver by any party hereto of any breach by any other party
hereto of any provision of this Agreement to be performed by such other party
shall be deemed a waiver of similar or dissimilar provisions at the time or at
any prior or subsequent time.

        19.  Headings.  The headings contained herein are solely for the
             --------
purposes of reference, are not part of this Agreement and shall not in any way
affect the meaning or interpretation of this Agreement.

        20.  Counterparts.  This Agreement may be executed in two or more
             ------------
counterparts, each of which shall be deemed to be an original but all of which

             --------------
the date of the First Closing, as defined in the Purchase Agreement (the
"Effective Date").  If the First Closing Agreement does not occur, this
 --------------
Agreement shall be null and void.

                             EMPLOYMENT AGREEMENT
                             --------------------

securities of any issuer whose securities are registered under the Securities
and Exchange Act of 1934, as amended, standing alone, be prohibited by this
Subsection (b) of this Section 10. For purposes of this paragraph, the term
"Restricted Enterprise" shall mean any person, corporation, partnership or other
 ---------------------
entity that is principally engaged in providing local data and/or voice
telecommunications services in Latin America. Following termination of the
Employment Term, upon request of the Company, the Employee shall notify the
Company of the Employee's then current employment status. For purposes of this
Agreement, the "Non-competition Term" shall mean the period beginning on the
                --------------------
Termination Date and ending on the six month anniversary, if less than one year
employment, and on the first anniversary of such date if more than one year.

         (c)  Non-solicitation.  During the Non-competition Term, the
              ----------------
Employee shall not, and shall not intentionally cause any other person to,
entice away from the Company, any of its subsidiaries or Affiliates, any person
who is an employee or customer of the Company, any of its subsidiaries or
Affiliates at the time of the Termination Date.

         (d)  Remedies.  The Employee agrees that any breach of the terms of
              --------
this Section 10 may result in irreparable injury and damage to the Company, its
subsidiaries and/or its Affiliates for which the Company, its subsidiaries
and/or its Affiliates may have no adequate remedy at law; the Employee therefore
also agrees that in the event of said breach or any threat of breach, the
Company, its subsidiaries and/or its Affiliates, as applicable, shall be
entitled to an immediate injunction and restraining order to prevent such breach
and/or threatened breach and/or continued breach by the Employee and/or any and
all persons and/or entities acting for and/or with the Employee, without having
to prove damages, in addition to any other remedies to which the Company, its
subsidiaries and/or its Affiliates may be entitled at law or in equity.  The
terms of this paragraph shall not prevent the Company, its subsidiaries and/or
its Affiliates from pursuing any other available remedies for any breach or
threatened breach hereof, including but not limited to the recovery of damages
from the Employee.  The Employee and the Company further agree that the
provisions of the covenants contained in this Section 10 are reasonable and
necessary to protect the businesses of the Company, its subsidiaries and
Affiliates because of the Employee's access to Confidential Information and his
material participation in the operation of such businesses.  Should a court,
arbitrator or other similar authority determine, however, that any provision of
the covenants contained in this Section 10 are not reasonable or valid, either
in period of time, geographical area, or otherwise, the parties hereto agree
that such covenants should be interpreted and enforced to the maximum extent to
which such court or arbitrator deems reasonable or valid.

     The existence of any claim or cause of action by the Employee against
the Company and/or its subsidiaries and/or its Affiliates, whether predicated on
this Agreement or otherwise, shall not constitute a defense to the enforcement
by the Company of the covenants contained in this Section 10.

in accordance with its terms.

the party to be charged.

     15. Severability.  If any provision of this Agreement, or any application
         ------------
thereof to any circumstances is invalid, in whole or in part, such provision or
application shall to that extent be severable and shall not affect other
provisions or applications of this Agreement.

         -------------
accordance with the internal laws of the State of New York, without reference to

[DIGINET LETTERHEAD APPEARS HERE]                                  Exhibit 10.11


March 29, 1998



Mr. Laurence A. Hinz
1015 33rd Street, NW #706
Washington, D.C. 20007


Dear Larry,

I am pleased to present to you a formal offer to join the Diginet Americas, Inc.
("Diginet") team and, as a partner, play a pivotal role in building Diginet
into a great telecommunications company. I am confident that you will make a
significant contribution to Diginet's ambitious growth plans, flourish
professionally, and enjoy the endeavor on many levels. You clearly are a very
accomplished professional, and I truly believe that Diginet represents an
excellent platform for your considerable talents and natural abilities.

The position's formal title is Chief Financial Officer. You will report
directly to me, the Company's Chief Executive Officer, with dotted line
reporting to the Company's President and COO, Francisco Amaro. Your direct
responsibilities will include, but not be limited to, five broad areas:

     .  Capital Formation- Leading the capital formation effort, as the company
        progresses through several rounds of private equity, vendor and/or
        OPIC/IFC/Ex-Im Bank debt facilities, a possible strategic investment,
        and onto the IPO and rounds of public high yield debt.

                             [Diginet Letterhead]

<PAGE>
                                                                               2

     .  Board of Directors/Shareholder "Management"- I anticipate that the
        Diginet Board of Directors will be very high powered and very involved
        in Diginet's development. You will have primary responsibility for
        interfacing with Investor and Outside Directors (including David
        Solomon, the former CFO of Brooks Fiber), and facilitating efficient
        Board dynamics. I suspect that you will find this Board-level exposure
        professionally stimulating.

     .  Vendor Relations- Diginet will soon be negotiating a multi-country
        strategic vendor contract, involving pricing, performance, and a long
        term debt facility. You will be a key member of the team that negotiates
        this critical transaction.

     .  M&A/Strategic Partnering- While there are no M&A or strategic partnering
        activities planned in the near term, I envision a potential strategic
        investment at the corporate level (candidates include ATT, Worldcom,
        Sprint, Teleglobe, Intermedia, wireless CLECs), and strategic
        investments at the country level to enhance Diginet's political/economic
        clout. As such M&A/Strategic Partnering activity develops, you will be
        intimately involved in this process.

     .  Classic Financial Management- Planning, budgeting, financial controls.

In addition to your central, line operating responsibilities, as a core member
of the management team, I anticipate that you actively will be involved in a
range of high-level decision making, including:

        .  Overall Corporate strategy and direction

        .  Key spectrum decisions throughout Latin America

        .  Establishing corporate culture and value-system

        .  Key sales and marketing decisions

        .  Establishment of in-country strategic/marketing alliances

        .  Creating and deploying new products/service offerings that leverage
           Diginet's transmission capabilities, lock-in customers, and provide
           Diginet with enduring competitive advantages

I believe that Diginet represents an entrepreneurial opportunity, with many
unique advantages. We have put together a remuneration package that provides you
with venture upside and rewards, while offering you downside protection. The
offer includes "market" cash compensation, a signing bonus and an attractive
initial stock option package that rewards you for value-creation and also has
the potential to significantly enhance your net worth.

In addition, you will have all of the excitement, challenges, and satisfaction
of building a business from "the ground floor up", without corporate politics.
You will have an opportunity to build a team that you respect professionally,
and enjoy working with on a personal level. You will have an opportunity to
create with us a company, and a work environment, that reflects your values,
that is humane, meritocritous, and equitable. You also will be challenged
intellectually in determining how best to "export" new telecom/datacom/IT
technologies and product/services to the infrastructure-deprived environments of
Latin America.

The key terms of the revised Job Offer are outlined in Exhibit A. I appreciate
the importance of this career decision for you, and I would be pleased to
discuss the offer with you in depth.

Larry, we very much look forward to working with you, and to making Diginet an
overwhelming success. While we have known each other only a very short time, I
am confident that you will play a critical role in Diginet's success and that
you will find the experience exceptionally satisfying intellectually,
emotionally, and financially.

         (a)  The death of the Employee ("Death").

termination based on: (i) the conviction of the Employee of any crime involving
the property or business of the Company or; (ii) the Employee's repeated,
reckless misconduct injurious to the Company and failure to cure such action
within ten (10) days after written demand for substantial improvement in
performance with reasonable detail delivered to the Employee by the Board.  For
all purposes of the Employee's employment by the Company, if the Employee's
employment is terminated for Cause, the effective date of such termination shall
be the date of delivery of the Cause Notice.

         (d)  The termination of employment by the Company for Disability.

         (e)  The termination of employment by the Company other than for
Cause,  Disability or Death.

"Good Reason" shall mean: (i)  any reduction in Base Salary, (ii) any material
- ------------
diminution in the Employee's position, duties or responsibilities, (iii) a
change of control of the Company (as defined below),  (iv) any relocation of the
corporate headquarters of Diginet Americas, Inc.  to a location that is more
than one hundred (100) miles from the present location of such corporate
headquarters.

         (g)  Termination by the Employee for other than Good Reason.

In the event of the termination of the Employee's employment, for whatever
reason (other than Death), the Employee agrees to cooperate upon reasonable
request with the Company, its subsidiaries and Affiliates and to be reasonably
available to the Company, its subsidiaries and Affiliates as a matter of
professional courtesy, with respect to continuing and/or future matters arising
out of the Employee's employment hereunder with the Company, its subsidiaries or
Affiliates, whether such matters are business-related, legal or otherwise.

     8.  Termination Payments.
         --------------------

         (a)  If the Employee's employment with the Company terminates, the
Company will pay the Employee (i) any accrued and unpaid Base Salary as of the
Termination Date and (ii) an amount equal to such reasonable and necessary
business expenses incurred by the Employee in connection with the Employee's
employment on behalf of the Company on or prior to the Termination Date but not
previously paid to the Employee (the "Accrued Compensation").
                                      --------------------

         (b)  If the Employee's employment with the Company terminates

Company with respect to such Base Salary, and shall continue to provide the
Employee with medical coverage and related benefits substantially comparable to
that provided generally to senior officers of the Company.

         (d)  Vesting of Options.  In the event the Employee's employment
              ------------------
terminates pursuant to Subsections (a), (d), (e) or (f) of Section 7 hereof, (i)
the portion of any options to acquire shares of the Company's common stock (the
"Common Stock") held by the Employee which are scheduled to become vested and
exercisable within six months of the Termination Date shall become vested and
exercisable on the Termination Date, (ii), any unvested shares of Common Stock
acquired by the Employee, pursuant to the exercise of options, which are
scheduled to vest within six months of the Termination date shall vest on the
Termination Date, and (iii) any vested options held by the Employee on the

                               ----------
of the Company's standard early exercise stock option agreement as in effect on
the Grant Date.  Notwithstanding the foregoing sentence or anything to the
contrary in any stock option agreement or plan, such options and any restricted
shares of Common Stock acquired

     9.  Change of Control.
         -----------------

         (a)  Notwithstanding the provisions of any agreement or
plan pursuant to which the Employee shall have been granted options to purchase
shares of the Company's capital stock ("Options") upon an IPO (as defined below)
                                        -------
or upon a Change in Control of the Company or a public announcement of an
agreement or arrangement which will result in a Change in Control, all such
Options granted to the Employee shall become fully vested and in the event that
the Employee's employment is terminated for any reason all such Options shall
not expire prior to the 181st day after the date of such termination.

         (b)  For purposes of this Agreement, a Change of Control shall be
deemed to have occurred if: (a) any "person" (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act")), is or becomes the "beneficial owner" (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities of the Company
(not including any securities acquired directly from the Company) representing
more than 30% of the combined voting power of the Company's then outstanding
securities; (b) during any period of two (2) consecutive years during the term
of this Agreement, individuals who at the beginning of such period constitute
the Board cease for any reason to constitute at least a majority thereof, unless
the election of each director who was not a director at the beginning of such
period has been approved in advance by directors representing at least two-
thirds of the directors then in office who were directors at the beginning of
the period; (c) the stockholders of the Company approve a merger or
consolidation of the Company with or into another unaffiliated entity, or the
merger of another unaffiliated entity into the Company or any subsidiary thereof
with the effect that immediately after such transaction the stockholders of the
Company immediately prior to such transaction hold less than fifty percent (50%)
of the total voting power of all securities generally entitled to vote in the
election of directors, managers or trustees of the entity surviving such merger
or consolidation; (d) the stockholders of the Company approve a plan for the
sale, lease or other transfer of all or substantially all of the Company's
assets to an unaffiliated person or group (as such term is used in Section
13(d)(3) of the Securities Exchange Act of 1934, as amended); or (e) the
adoption by the stockholders of the Company of a plan relating to the
liquidation or dissolution of the Company.

         (c)  For the purposes of the Agreement, an IPO shall mean the first
registration under the Securities Act of 1933, as amended, of any shares of the
Company's capital stock.

<PAGE>

         (d)  Subject to Subsection (e) of this Section 9, in the event that the
Employee's employment terminates pursuant to Subsection (c) of Section 7 hereof,
the Company shall have a call right, enabling the Company (or its designee) to
require the Employee (or his successor or representative, as the case may be) to
sell to the Company (or its designee) all shares of Common Stock held by the
Employee at a per share purchase price equal to the lesser of the amount paid by
the Employee for each share or the Fair Market Value of each such share as of
the date of exercise of such call right.  The call right shall be exercisable by
the Company for twelve months after the later of (i) the Employee's termination
of employment and (ii) the exercise of the Option.

         (e)  The Company's call right as provided herein shall expire at the
time of  an IPO.

         (f)  For purposes of this Section 9, the term "Fair Market Value" of a
                                                        -----------------
share of Common Stock on any date means the value of such share of Common Stock
as determined in good faith by the Board.

     10. Employee Covenants.
         ------------------

         (a)  Unauthorized Disclosure.  The Employee agrees and understands
              -----------------------
that in the Employee's position with the Company, the Employee will be exposed
to and will receive information relating to the confidential affairs of the
Company, its subsidiaries and Affiliates, including but not limited to technical
information, intellectual property, business and marketing plans, strategies,
customer information, other information concerning the products, promotions,
development, financing, expansion plans, business policies and practices of the
Company, its subsidiaries and Affiliates, and other forms of information
reasonably considered by the Company to be confidential and in the nature of
trade secrets ("Confidential Information").  The Employee agrees that during the
                ------------------------
Employment Term and  for a commercially reasonable period thereafter, the
Employee will not disclose such Confidential Information, either directly or
indirectly, to any third person or entity without the prior written consent of
the Company.  Upon termination of the employment Term, the Employee will supply
or make available to the Company in a timely manner all property, keys, notes,
memoranda, writings, lists, files, reports, customer lists, correspondence,
tapes, disks, cards, surveys, maps, logs, machines, technical data or any other
tangible product or document which has been produced by, received by or
otherwise submitted to the Employee during or prior to the Employment Term.

          Confidential Information shall not include information that: (i) is
previously know by Employee at the time of disclosure without obligation of
confidence, or without breach of this Agreement; (ii) is publicly disclosed
through no wrongful act of Employee; (iii) is received from a third party having
the right to lawfully possess and disclose same and without breach of this
Agreement; (iv) is independently developed by Employee without access or
reference to the Confidential Information, (v) is approved for release by
authorization of the Company; or (vi) is required to be disclosed by a court or
regulatory body of competent jurisdiction pursuant to applicable law or
regulation.

                                       6
<PAGE>

         (b)  Non-competition.  By and in consideration of the Company's
              ------------------
entering into this Agreement and the payments to be made and benefits to be
provided by the Company hereunder, and further in consideration of the
Employee's exposure to the Confidential Information of the Company, its
subsidiaries and Affiliates, the Employee agrees that the Employee will not,
during the  Employment Term, and thereafter during the "Non-competition Term"
                                                        --------------------
(as defined below), directly or indirectly, own, manage, operate, join, control,
be employed by, or participate in the ownership, management, operation or
control of, or hold any position as an officer, consultant, independent
contractor, employee or partner in, any "Restricted Enterprise" (as defined
                                         ---------------------
below); provided that in no event shall ownership of less than 1% of the
        --------
outstanding equity securities of any issuer whose securities are registered
under the Securities and Exchange Act of 1934, as amended, standing alone, be
prohibited by this Subsection (b) of this Section 10.  For purposes of this
paragraph, the term "Restricted Enterprise" shall mean any person, corporation,
                     ---------------------
partnership or other entity that is principally engaged in providing local data
and/or voice telecommunications services in Latin America.  Following
termination of the Employment Term, upon request of the Company, the Employee
shall notify the Company of the Employee's then current employment status.  For
purposes of this Agreement, the "Non-competition Term" shall mean the period
                                 --------------------
beginning on the Termination Date and ending on the first anniversary of such
date.

         (c)  Non-solicitation.  During the Non-competition Term, the
              ----------------
Employee shall not, and shall not intentionally cause any other person to,
entice away from the Company, any of its subsidiaries or Affiliates, any person
who is an employee or customer of the Company, any of its subsidiaries or
Affiliates at the time of the Termination Date.

         (d)  Remedies.  The Employee agrees that any breach of the terms of
              --------
this Section 10 may result in irreparable injury and damage to the Company, its
subsidiaries and/or its Affiliates for which the Company, its subsidiaries
and/or its Affiliates may have no adequate remedy at law; the Employee therefore
also agrees that in the event of said breach or any threat of breach, the
Company, its subsidiaries and/or its Affiliates, as applicable, shall be
entitled to an immediate injunction and restraining order to prevent such breach
and/or threatened breach and/or continued breach by the Employee and/or any and
all persons and/or entities acting for and/or with the Employee, without having
to prove damages, in addition to any other remedies to which the Company, its
subsidiaries and/or its Affiliates may be entitled at law or in equity.  The
terms of this paragraph shall not prevent the Company, its subsidiaries and/or
its Affiliates from pursuing any other available remedies for any breach or
threatened breach hereof, including but not limited to the recovery of damages
from the Employee.  The Employee and the Company further agree that the
provisions of the covenants contained in this Section 10 are reasonable and
necessary to protect the businesses of the Company, its subsidiaries and
Affiliates because of the Employee's access to Confidential Information and his
material participation in the operation of such businesses.  Should a court,
arbitrator or other similar authority determine, however, that any provision of
the covenants contained in this Section 10 are not reasonable or valid, either
in period of time, geographical area, or otherwise, the parties hereto agree
that such covenants should be interpreted and enforced to the maximum extent to
which such court or arbitrator deems reasonable or valid.

                                       7
<PAGE>

          The existence of any claim or cause of action by the Employee against
the Company and/or its subsidiaries and/or its Affiliates, whether predicated on
this Agreement or otherwise, shall not constitute a defense to the enforcement
by the Company of the covenants contained in this Section 10.

     11. Non-Waiver of Rights.  The failure to enforce at any time the
         --------------------
provisions of this Agreement or to require at any time performance by any other
party of any of the provisions hereof shall in no way be construed to be a
waiver of such provisions or to affect either the validity of this Agreement or
any part hereof, or the right of any party to enforce each and every provision
in accordance with its terms.

     12. Notices.  Every notice relating to this Agreement shall be in
         -------
writing and shall be given by personal delivery or by registered or certified
mail, postage prepaid, return receipt requested.

     13. Binding Effect/Assignment.  This Agreement shall inure to the
         -------------------------
benefit of and be binding upon the parties hereto and their respective heirs,
executors, personal representatives, estates, successors (including, without
limitation, by way of merger) and assigns.  Notwithstanding the provisions of
the immediately preceding sentence, the Employee shall not assign all or any
portion of this Agreement without the prior written consent of the Company.

     14. Entire Agreement.  This Agreement and the Option Agreement,
         ----------------
dated July 5, 1999, between the Employee and the Company, sets forth the entire
understanding of the parties hereto with respect to the subject matter hereof
and supersedes all prior agreements, written or oral, between them as to such
subject matter.  This Agreement may not be amended, nor may any provision hereof
be modified or waived, except by an instrument in writing duly signed by the
party to be charged.

     15. Severability.  If any provision of this Agreement, or any
         ------------
application thereof to any circumstances is invalid, in whole or in part, such
provision or application shall to that extent be severable and shall not affect
other provisions or applications of this Agreement.

     16. Governing Law.  This Agreement shall be governed by and
         -------------
construed in accordance with the internal laws of the State of New York, without
reference to the principles of conflict of laws.

     17. Arbitration.  The Employee agrees that, at the Company's election
         -----------
(which election may be made on the Company's sole and absolute discretion at any
time prior to the commencement of a judicial proceeding by the Company or, in
the event instituted by the Employee, at any time prior to the last day to
answer and/or respond to a summons and/or complaint made by the Employee), any
dispute of any kind, nature or

                                       8
<PAGE>

description between the parties hereto in respect of arising out of this
Agreement, the Employee's employment by the Company, and/or the termination
thereof, shall be submitted to binding arbitration in the District of Columbia
before the American Arbitration Association.

     18. Modifications and Waivers.  No provision of this Agreement may be
         --------------------------
modified, altered or amended except by an instrument in writing executed by the
parties hereto.  No waiver by any party hereto of any breach by any other party
hereto of any provision of this Agreement to be performed by such other party
shall be deemed a waiver of similar or dissimilar provisions at the time or at
any prior or subsequent time.

     19. Headings.  The headings contained herein are solely for the
         --------
purposes of reference, are not part of this Agreement and shall not in any way
affect the meaning or interpretation of this Agreement.

     20. Counterparts.  This Agreement may be executed in two or more
         ------------
counterparts, each of which shall be deemed to be an original but all of which
together shall constitute one and the same instrument.

     IN WITNESS WHEREOF, the Company has caused this Agreement to be
executed by authority of its Board of Directors, and the Employee has hereunto
set his hand, on the day and year first above written.

[DIGINET Letterhead appears here]


October 5, 1997


John B. Holmblad
11686 Fox Glen Drive
Oakton, Virginia 22124


Dear John,

I am please to present to you a formal job offer to join the Diginet Americas,
Inc. ("Diginet") team and play a pivotal role in building Diginet into a great
telecommunications company.  I am confident that you will make a significant
contribution to Diginet's ambitious growth plans, flourish professionally, and
enjoy the endeavor on many levels.

The formal title that we propose for you is Chief Technical Officer and Senior
Vice President Operations.  As we have discussed, this title does not adequately
describe the pivotal role that I envision you playing.  You will be one of three
executives, including myself and the Chief Operating Officer, who will lead the
Company and be responsible for its growth and ultimate success.  In this
capacity, I anticipate that you will be actively involved with:

        .  Board of Director-level decision making

        .  Overall Corporate strategy and direction

        .  Capital formation

        .  Strategic partnering, M&A

        .  Key spectrum decisions throughout Latin America

        .  Establishing corporate culture and value-system


                             [DIGINET Letterhead]

<PAGE>

                                                                               2

        .  Key hiring decisions, including selection of key executive positions
           in Latin America

        .  Key sales and marketing decisions

        .  Establishment of in-country strategic/marketing alliances

        .  Creating and deploying new product/service offerings that leverage
           Diginet's transmission capabilities, lock-in customers, and provide
           Diginet with enduring competitive advantages

I anticipate that we will work closely together through various rounds of
private equity and debt financings, and that you will be involved in all phases
of the IPO process, including selection of the lead underwriters, production of
the IPO prospectus, and participation in the marketing "road show".  I suspect
that you will find this capital formation exposure quite enjoyable, and that the
experience will certainly enhance your career profile.

Your direct responsibilities will include, but not be limited to, everything
involved in designing, building, maintaining, and growing Diginet's "wireless
fiber" networks throughout the major urban markets of Latin America.  I
anticipate that this will include negotiating with vendors, assembling
management teams at both the U.S. and Latin American levels, establishing
U.S.-levels of quality and customer service, negotiating with Latin regulatory
authorities, and intelligently leveraging Diginet's transmission capabilities
with value-added product/services.

I am very sensitive to the importance of the career decision that currently
confronts you, your role as sole family "bread winner", and to the risks that
one normally associates with early stage companies.  As such, we have put
together a job offer that addresses many of these concerns, and, in my opinion,
provides you with venture upside and rewards, while offering you unique downside
protection.  The offer includes "market" cash compensation, and a stock option
package currently valued at $700,000 today (as determined by Series A
Convertible Preferred investors), and hopefully worth multiples of this figure
in the not too distant future.

                                                                               3


I have complete confidence in our ability to furnish Diginet with the proper
levels of capital to effectively grow the Company into a world-class
telecommunications competitor. This is based upon my fund-raising track record
(over $50 million in 2.5 years for Radio Movil Diginet Americas, Inc.), the ease
with which we have established a $2 million Bridge Financing facility (and the
high quality of the Bridge Financing investors), and the tremendous response
that Diginet has received after being in the capital markets only a short period
of time (including having received a term sheet for a $15 million equity
investment). The level of our personal investment in Diginet (almost $2 million
to date) further highlights our level of confidence.

Nonetheless, I can fully appreciate your concerns regarding Diginet's short and
medium-term financial health. As such, I am prepared to completely eliminate
this risk factor, so that you can fully assess the Diginet opportunity, and how
it fits with your career goals and ambitions. As a backstop to Diginet's
corporate financial resources, I will personally guarantee your cash
compensation for the next 12 months. This is a highly unusual gesture, and one
that reflects both my level of confidence in Diginet's future, and my sense that
you are ideally suited to play a pivotal role in Diginet's growth.

As we have discussed, in my experience, participation in a successful emerging
growth company provides many unique and rewarding benefits - You will have an
opportunity to build a management team that you respect professionally, and
enjoy working with on a personal level. You will have an opportunity to utilize
your professional experiences to mentor the next generation of Latin American
telecom/datacom engineers and senior executives. You will have an opportunity to
create a company, and a work environment, that reflects your values, that is
humane and equitable, and brings "economic democracy" to Latin America. You will
be challenged intellectually in determining how best to "export" new
telecom/datacom/IT technologies and product/services to the
infrastructure-deprived environments of Latin America.

                                                                               4


You will be part of a team of people that will be dramatically improving Latin
American telecommunications infrastructure, thereby helping these counties and
