                               PROSPECTUS SUMMARY

  The information below is only a summary of more detailed information included
in other sections of this prospectus. This summary may not contain all the
information that is important to you or that you should consider before buying
shares in this offering. The other information is important, so please read
this entire prospectus carefully.

                              VIA NET.WORKS, Inc.


  VIA NET.WORKS is a leading international provider of Internet access and
services focused on small and mid-sized businesses in Europe and Latin America.
By targeting these customers and regions, we are positioned to capitalize on
some of the most rapidly growing areas of the Internet market. Both of these
regions have a relatively low number of total Internet users, and small and
mid-sized businesses in each region have a relatively low number of Internet
services available to them. By choosing to serve these market segments, we have
the opportunity to sell our services to a large number of small and mid-sized
businesses who have identifiable Internet needs but little or no Internet
experience. Once we have developed relationships with these customers, we can
upgrade them from entry-level Internet access services to more sophisticated
and higher margin products and services like web hosting, virtual private
networks and e-commerce solutions which will allow them to compete in both
local and global markets.

  Since our founding in late 1997, we have rapidly established our
international presence by acquiring, integrating and growing 17 business-
focused Internet services providers in 11 European and Latin American
countries. As of September 30, 1999, pro forma for an acquisition we made after
September 30, 1999, we had 80,600 customers in Europe, of which 44.2% were
businesses, and 34,900 customers in Latin America, of which 40.3% were
businesses. Pro forma for this acquisition, as of September 30, 1999 we hosted
17,000 web sites and had registered 46,700 domain names. For the nine months
ended September 30, 1999, we had pro forma revenue of $42.1 million and pro
forma net losses of $30.4 million. To date, our operations have been funded by
investments of $181.0 million from our current investors, which include The
Centennial Funds, Norwest Equity Capital, Telecom Partners II, HarbourVest
International, Providence Equity Partners, Verio Inc. and Boston Millennia
Partners.

  We are a customer-focused sales, marketing and service organization. We
leverage our local marketing, sales and customer care efforts with the benefits
of our global scale by providing our local operations international network
capacity, marketing support, capital and management resources. We believe that
our local focus combined with our global capabilities will allow us to increase
both our market share and revenue.

Our Products and Services

  We offer a suite of bundled and stand-alone Internet products and services
which can be tailored to the individual needs of our small and mid-sized
business customers. Our products and services include

  . dedicated high speed and dial-up Internet access

  . hosting of customer web sites

  . co-location services, where a customer places equipment in our facilities
    for the purposes of hosting software, database, web site and other
    applications

  . e-mail services

  . e-commerce solutions including secure electronic payment processing,
    electronic procurement and business portal design and hosting

                                       1

  . Internet virtual private networks which provide individual commercial
    customers with greater security for their electronic communications over
    the Internet

  . domain name registration of Internet addresses, such as
    www.customername.com

  . Internet security products, which protect the integrity of customer data
    and networks, authenticate users and provide secure data transmissions

Our Markets

  Internet access and services markets are among the fastest growing segments
of the global telecommunications marketplace. Total spending by businesses on
Internet access and services in Western Europe is projected by International
Data Corporation to grow 32.9% annually from $3.0 billion in 1998 to $12.5
billion in 2003. According to The Yankee Group, Internet access revenues in
Latin America are forecasted to increase from an estimated $750.0 million in
1998 to $6.0 billion in 2002, or 68.2% annually. Favorable trends which should
help fuel continued growth in both geographic markets include

  . increasing availability and affordability of computer hardware

  . increasing Internet penetration, which is the ratio of World Wide Web
    users to total population

  . increasing adoption of the Internet and related technologies to drive
    productivity and e-commerce revenue

  . continuing telecommunications industry deregulation, which encourages
    improved infrastructure and competitive pricing

Our Network

  We own and operate a European and trans-Atlantic network which carries
Internet traffic generated by our operating companies. The backbone of this
network provides 155 Mbps of redundant capacity on two fiber optic rings. The
first ring provides trans-Atlantic capacity between New York City and London.
The second ring provides pan-European capacity which we will initially use to
establish network connection points in seven European cities. We currently have
network connection points in London, Dusseldorf and Amsterdam and plan to
establish a Paris connection point by the end of 1999 and connection points in
three additional cities during 2000. We believe that combining the transmission
capacity requirements of our operating companies onto our network increases
efficiency, reduces costs and results in higher service quality than our
operating companies could obtain on their own. We manage the European and
trans-Atlantic network from a regional network operations center located in
Germany. This facility provides network monitoring and service 24 hours a day,
seven days a week. We also operate 109 network points of presence throughout
Europe and Latin America which provide our customers with access to the
Internet. We plan to add points of presence to further expand our international
service capabilities.

Our Strategy

  Our goal is to become the premier international provider of Internet access
and services to small and mid-sized businesses in Europe and Latin America. We
intend to reach our goal by

  . maintaining a strong local presence through locally managed operating
    companies

  . leveraging our brand name and international network

  . delivering single-source Internet solutions to our customers

  . delivering quality customer service supported by continued investment in
    billing, back-office and customer care systems

  . continuing investment in network infrastructure and product development

  . accelerating our growth through strategic acquisitions

  . our combined pro forma financial data for the year ended December 31,
    1998 and for the nine months ended September 30, 1999

  . our pro forma as adjusted balance sheet data as of September 30, 1999,
    which give effect to our sale of    shares of common stock at an assumed
    initial public offering price of $   per share less underwriting fees and
    estimated offering expenses

   Our historical statement of operations data for the period from inception,
June 13, 1997, to December 31, 1997 and for the year ended December 31, 1998
are derived from our audited consolidated financial statements. Our statement
of operations data for the nine months ended September 30, 1998 and 1999 and
our balance sheet data as of September 30, 1999 are derived from our unaudited
interim financial statements and, in the opinion of our management, include all
material adjustments, consisting only of normal and recurring adjustments,
necessary for a fair presentation of the results of operations and financial
condition. Operating results for the nine months ended September 30, 1999 are
not necessarily indicative of the results that may be expected for the full
year.

  Our pro forma statement of operations and other financial data for the year
ended December 31, 1998 and the nine months ended September 30, 1999 give
effect to our acquisition of 15 companies between January 1, 1998 and
September 30, 1999 and our acquisition of InfoAcces, which was completed after
September 30, 1999, as though these acquisitions had occurred on January 1,
1998. The pro forma balance sheet data and operating statistics as of September
30, 1999 give effect to our acquisition of InfoAcces. The pro forma statement
of operations and balance sheet data also give effect to the conversion of all
of our outstanding mandatorily redeemable convertible preferred stock into
common stock and the pro forma balance sheet data are further adjusted to
reflect this offering. The pro forma financial data for the year ended December
31, 1998 and the nine months ended September 30, 1999 are not necessarily
indicative of the results that would have occurred if the transactions had been
consummated as of January 1, 1998 and are not intended to indicate expected
results for any future period.

  As used in the table below, "EBITDA" represents earnings or loss from
operations before interest, taxes, depreciation, amortization and non-cash
stock compensation charges. The primary measure of operating performance is net
earnings. Although EBITDA is a measure commonly used in our industry, it should
not be considered an alternative to net earnings, when determined in accordance
with generally accepted accounting principles or GAAP, as an indicator of
operating performance or as an alternative to cash flows from operating
activities, determined in accordance with GAAP. In addition, the measure of
EBITDA we use may not compare to other similarly titled measures used by other
companies.

  The summary consolidated and combined pro forma financial data shown below
should be read together with our audited consolidated financial statements, our
unaudited interim financial statements, our unaudited pro forma condensed
combined financial statements, our acquired companies' financial statements and
related notes, and other financial information including "Management's
Discussion and Analysis of Financial Condition and Results of Operations," all
of which are included elsewhere in this prospectus.

                                  RISK FACTORS

  You should carefully consider the following risk factors and all of the other
information included in this prospectus before purchasing our common stock.
Investing in our common stock involves a high degree of risk. Any of the
following risks could cause our quarterly operating results to fluctuate or
materially adversely affect our business, operating results or financial
condition and could result in a complete loss of your investment.

Risks Related to our Business

We are not profitable and do not expect to achieve profitability in the near
future, if at all.

  We have not achieved profitability. We expect to continue to incur net losses
for the foreseeable future and may never become profitable. We incurred net
losses of $321,000 from inception through December 31, 1997. For the year ended
December 31, 1998, we incurred additional net losses of $5.3 million. For the
nine months ended September 30, 1999, we incurred additional net losses of
$16.2 million and had an accumulated deficit of $21.9 million as of September
30, 1999.

  We expect to continue to incur net losses in future periods as we acquire and
invest in operating companies and the infrastructure required to support them.
So long as we continue to make these acquisitions, we will continue to amortize
a substantial amount of goodwill, which will reduce our earnings.

We have a history of negative cash flow, and we may never achieve positive cash
flow.

  For the year ended December 31, 1998, we had losses from operations, before
depreciation and amortization, of $4.8 million. For the nine months ended
September 30, 1999, we had losses from operations, before depreciation and
amortization, of $9.1 million. Additionally, we used $14.4 million in 1998 and
$61.7 million in the first nine months of 1999 to acquire operations and fixed
assets. If we are unable to increase our revenue to cover our costs and
investment expenditures, we will continue to experience negative cash flow.

We may not be able to obtain sufficient funds to execute our business plan.

  We expect that the net proceeds of this offering will fund our operations for
the next 12 months. After we have used the net proceeds from this offering, we
will need to obtain additional financings to fund operations, capital
expenditures for expansion of network and information systems, and
acquisitions. If we are unable to obtain these financings on favorable terms,
we may be unable to implement our business plan.

Our combined operating history is limited and may not be indicative of our
future performance.

  Although a number of the operating companies we have acquired have been in
operation for some time, VIA itself has a limited history of operations.
Consequently, the financial information in this prospectus may not be
indicative of our future performance.

Because we have grown rapidly and we expect our growth to continue, we may have
difficulty managing our growth effectively, which could adversely affect the
quality of our services and the results of our operations.

  We have grown rapidly and expect to continue to grow rapidly by acquiring new
companies, increasing the number of customers served and increasing the number
and types of products and services we offer. We have acquired 17 companies
since June 1998 and the total number of our employees grew from five to 798
between June 1, 1998 and October 31, 1999. To manage our expected growth
effectively, we must

  . implement additional management information systems

  . develop additional operating, administrative, financial and accounting
    systems and controls

  . hire and train additional personnel

                                       6
<PAGE>

  If we are unable to meet these demands, the quality of our services may
suffer, causing us to lose customers and revenues.

If we fail to integrate operating systems, networks and management of our
acquired companies successfully, we may suffer operating inefficiencies and
reduced operating cash flow.

  We may not be able to integrate our acquired companies successfully because
we currently operate in 11 different countries with different governmental
regulations, languages, customs, currencies and availabilities of
telecommunication capacity to carry data. We will have to commit substantial
management, operating, financial and other resources to integrate our operating
companies and implement our business model, which will reduce our operating
cash flow.

Because we operate in markets where extended vacations are typical, and since
in some of these markets, we receive a portion of our revenues based on
customer usage, we may experience seasonal variation in our quarterly revenue
and operating results that could cause our stock price to decline.

  In Europe and Latin America, four or more weeks of vacation is typical and
often mandated under law. As a result, extended summer and winter holiday
vacations are common and it is difficult to attract new customers during these
periods. In these markets, our customers also pay their telephone companies for
the number of minutes they spend on-line, even if we provide a local telephone
number that they can use for access. We may receive a portion of these fees
from the telephone companies as payment for generating usage, and customer
usage generally declines in the summer months and in December. As a result, we
may experience lower revenues during these periods and our operating results
may be affected. To the extent our quarterly results fluctuate more widely than
expected by us, securities analysts and investors, our stock price could
decline.

We face increasing competition for the purchase of local Internet services
providers, which may impede our ability to make future acquisitions or may
increase the cost of these acquisitions.

  Our business strategy depends, in part, upon our ability to identify and
acquire new local Internet services providers that meet our acquisition
criteria. In pursuing these opportunities, we compete with other Internet
services providers, local, regional, national and global telecommunication
companies and other buyers. These competitors may drive up the price of our
acquisition targets or may acquire our acquisition targets. Many of these
competitors are larger than we are and have greater financial and other
resources than we have. Increasing competition has raised the price we have
paid for acquisitions in some markets and may continue to do so. In addition,
our acquisition targets may find our competitors more attractive because they
may have greater resources, may be willing to pay more, or may have a more
compatible operating philosophy.

Financial information on which we rely to make future acquisitions may not be
accurate, which may result in our acquiring undisclosed liabilities or
experiencing lower than expected operating results.

  The companies we target for acquisition typically do not have audited
financial statements and have varying degrees of internal controls and detailed
financial information. As a result, we may acquire undisclosed liabilities or
experience lower-than-expected revenues or higher-than-expected costs, which
could adversely affect our operating results.

Fluctuations in the exchange rate between the U.S. dollar and the various
currencies in which we conduct business may affect our operating results.

  Fluctuations in foreign currency exchange rates may adversely affect our
revenues, expenses and results of operations as well as the value of our assets
and liabilities. These fluctuations may adversely affect the comparability of
period-to-period results. For example, the value of the Brazilian Real
fluctuated by 45.6% in relation to the U.S. dollar during the nine months ended
September 30, 1999 and ended the period 37.2% lower than its value to the U.S.
dollar in the beginning of the year. Since each Real converted to fewer U.S.
dollars, our U.S. dollar revenue was reduced.

                                       7
<PAGE>

Logistical problems or economic downturns that could result from the
introduction of the Euro may affect our ability to operate and adversely impact
our operating results.

  On January 1, 1999, 11 of the 15 European Union member countries adopted the
Euro as their common legal currency, at which time their respective individual
currencies became fixed at a rate of exchange to the Euro, and the Euro became
a currency in its own right. During a January 1, 1999 to January 1, 2002
transition period, we must manage transactions with our customers and our
third-party vendors who conduct business in Euro participating countries in
both the Euro and the individual currencies. If we, our customers or our
vendors experience systems problems in converting to the Euro, we could be
unable to bill and collect from customers or pay vendors for services, and our
operating results could be materially adversely affected.

  The establishment of the European Monetary Union may have a significant
effect on the economies of the participant countries. Since a substantial
portion of our revenue will be denominated in the Euro or currencies of
European Union countries, our operating results could be adversely affected if
there is a downturn in the economies of participating countries or if the Euro
weakens against other currencies.

Our brand names are difficult to protect and may infringe on the intellectual
property rights of third parties.

  We are aware of other companies using our trademarks and variations of those
marks. The users of these or similar marks may have senior rights if they were
ever to assert a claim against us for trademark infringement. If an
infringement suit were instituted against us, even if groundless, it could
result in substantial litigation expenses in defending the suit. If such a suit
were to be successful, we could be forced to cease using the mark and to pay
damages.

  In addition, we have applied to register several of our trademarks in various
countries. Our application to register in Argentina the trademark "VIA Net
Works Argentina" has been opposed by a third party. If any of our applications
are unsuccessful, we may be required to discontinue the use of those
trademarks.

Risks Related to our Industry

Regulatory and economic conditions of the countries where our operating
companies are located are uncertain and may decrease demand for our services,
increase our cost of doing business or otherwise reduce our business prospects.

  Our operating companies are located in countries with rapidly changing
regulatory and economic conditions which may affect the Internet services
industry. Any new law or regulation pertaining to the Internet or
telecommunications, or the application or interpretation of existing laws,
could decrease demand for our services, increase our costs or otherwise reduce
our profitability or business prospects. Specific examples of the types of laws
or regulations that could adversely affect us include laws that

  . impose taxes on transactions made over the Internet

  . impose telecommunications access fees on Internet services providers

  . directly or indirectly affect telecommunications costs generally or the
    costs of Internet telecommunications specifically

  . prohibit the transmission over the Internet of various types of
    information and content

  . impose requirements on Internet services providers to protect Internet
    users' privacy

  . increase the likelihood or scope of competition from telecommunications
    or cable companies

  For example, some states of Brazil impose a tax of up to 30% on revenues
generated by communications services. There has been no judicial determination
that Internet access services constitute communications services. If Internet
services providers are ultimately required to pay this tax, our Brazilian
operations would be negatively and significantly impacted.


                                       8
<PAGE>

  These laws could require us to incur costs to comply with them or to incur
new liability. They could also increase our competition or change our
competitive environment so that customer demand for our products and services
is affected. For a discussion of specific regulatory proposals that may affect
our business, see "Business--Regulatory Matters."

  In addition to risks we face from new laws or regulations, we face
uncertainties in connection with the application of existing laws to the
Internet. It may take years to determine the manner in which existing laws
governing issues like property ownership, libel, negligence and personal
privacy will be applied to communications and commerce over the Internet.

Increasing competition for customers in our markets may cause us to reduce our
prices or increase spending, which may negatively affect our revenues and
operating results.

  There are competitors in our markets with more significant market presence
and brand recognition and greater financial, technical and personnel resources
than we have. As a result of this competition, we currently face and expect to
continue to face significant pressure to reduce our prices and improve the
products and services we offer. Although the competitors we face vary depending
on the market and the country, these competitors may include local and regional
Internet services providers, telecommunication companies and cable companies.
Some of our competitors, especially the telecommunications companies, have
large networks in place as well as a significant existing customer base.

If demand for Internet services in our markets does not grow as we expect, our
ability to grow our revenues will be negatively affected.

  Internet use in our markets is relatively low. If the market for Internet
services fails to develop, or develops more slowly than expected, we may not be
able to increase our revenues. Obstacles to the development of Internet
services in our markets include:

  . low rates of personal computer ownership and usage

  . lack of developed infrastructure to develop Internet access and
    applications

  . limited access to Internet services

We are in a rapidly evolving industry in which the products and services we
offer, their methods of delivery and their underlying technologies are changing
rapidly, and if we do not keep pace with these changes, we may fail to retain
and attract customers which would reduce our revenues.

  The Internet services market is characterized by changing customer needs,
frequent new service and product introductions, evolving industry standards and
rapidly changing technology. Our success will depend, in part, on our ability
to recognize and respond to these changes in a timely and cost-effective
manner. If we fail to do so, we will not be able to compete successfully.

We rely on telecommunications companies in our markets to provide our customers
with reliable access to our services, and failures or delays in providing
access could limit our ability to service our customers and impact our revenues
and operating results.

  Our customers access our services either through their normal telephone lines
or dedicated lines provided by local telecommunications companies specifically
for that use. In some of our markets, we experience delays in delivery of new
telephone lines that have prevented our customers from accessing our services.
These delays result in lost revenues. Additionally, some local
telecommunications companies that provide Internet services provide delivery of
telephone or dedicated lines to their Internet customers on a preferential
basis, which may cause us to lose current and potential customers. We also
lease network capacity from telecommunications companies and rely on the
quality and availability of their service. These companies may experience

                                       9
<PAGE>

disruptions of service which could disrupt our services to, or limit Internet
access for, our customers. We may not be able to replace or supplement these
services on a timely basis or in a cost-effective manner, which may result in
customer dissatisfaction and lost revenues.

We depend on the reliability of our network, and a system failure or a breach
of our security measures could result in a loss of customers and reduced
revenues.

  We are able to deliver services only to the extent that we can protect our
network systems against damages from telecommunication failures, computer
viruses, natural disasters and unauthorized access. Any system failure,
accident or security breach that causes interruptions in our operations could
impair our ability to provide Internet services to our customers and negatively
impact our revenues and results of operations. To the extent that any
disruption or security breach results in a loss or damage to our customer's
data or applications, or inappropriate disclosure of confidential information,
we may incur liability as a result. In addition, we may incur additional costs
to remedy the damages caused by these disruptions or security breaches.

If we fail to attract and retain qualified personnel or lose the services of
our key personnel, our operating results may suffer.

  Our success depends on our key management, engineers, sales and marketing
personnel, technical support representatives and other personnel, many of whom
may be difficult to replace. If we lose key personnel, we may not be able to
find suitable replacements which may negatively affect our business. In
addition, since the demand for qualified personnel in our industry is very
high, we may have to increase the salaries and fringe benefits we may offer to
our personnel, which may affect our operating results. We do not maintain key
person life insurance on, or restrictive employment agreements with, any of our
executive officers.

We may be liable for information disseminated over our network.

  We may face liability for information carried on or disseminated through our

The Year 2000 issue could impair our ability to provide services to our
customers, increase our costs, or reduce our revenues or profitability.

  Year 2000 issues may adversely affect our business and our customers'
businesses. Many computer systems may fail or malfunction because they are
unable to distinguish 21st century dates from 20th century dates. We have
incurred costs to upgrade our computers to address the year 2000 issue and may
in the future incur additional costs. Our customers may also need to incur
costs to either upgrade their computers or correct any problems their computers
may encounter, which may reduce our revenues by diverting our customers'
information systems resources away from our products and services. In addition,
if our computer systems or those of our telecommunications suppliers fail or
malfunction as a result of Year 2000 issues, our ability to provide services to
our customers will be disrupted, which could result in lost revenues, lost
customers or claims for damages, which could lead to costly litigation. For
information on how we are addressing year 2000 issues, see "Management's
Discussion and Analysis of Financial Condition and Results of Operations--Year
2000 Readiness Disclosure."

Risks Related to this Offering

We have discretion over the use of all of the net proceeds from this offering
and may fail to use them effectively to grow our business.

  We will retain discretion over how to use the net proceeds of this offering.
Because the proceeds are not required to be allocated to any specific
investment or transaction, you will not be able to determine at this time the
value or appropriateness of our use of the proceeds.

You will pay a higher price for our common stock than was paid by existing
stockholders and will experience immediate and substantial dilution.

  If you purchase common stock in this offering, you will pay more for your
shares than the amounts paid by existing stockholders for their shares. As a
result, assuming an initial public offering price of $    per share, you will
experience immediate and substantial dilution of approximately $    per share.

41,951,321, or   %, of our total outstanding shares may be sold into the market
in the near future. These sales could cause the market price of our common
stock to drop significantly, even if our business is doing well.

  After this offering, we will have outstanding     shares of common stock.
This includes the     shares we are selling in this offering, which may be
resold in the public market immediately. The remaining  %, or 41,951,321
shares, of our total outstanding shares will become available for resale in the
public market, subject to restrictions under federal securities laws, as shown
in the chart below. For information regarding these restrictions, see "Shares
Eligible for Future Sale."

  As restrictions on resale end, the market price could drop significantly if
the holders of these restricted shares sell them or are perceived by the market
as intending to sell them.

                        underwriters. However, the underwriters can waive this
                        restriction and allow these stockholders to sell their
                        shares at any time.

                        securities laws.

  In addition, holders of 40,326,676 shares of common stock and non-voting
common stock will be entitled to registration rights with respect to their
common stock. If these holders exercise their registration rights, causing a
large number of shares to be sold in the public market, our market price may
drop significantly.

Our stock has not traded publicly and may not trade actively after this
offering.

  Prior to this offering, you could not buy or sell our common stock publicly.
We cannot assure you that an active public trading market for our stock will
develop or be sustained after this offering.

The market price of our common stock, like the market prices of stocks of other
Internet-related and technology companies, may fluctuate widely and rapidly.

  The securities of many companies have experienced extreme price and volume
fluctuations in recent years, often unrelated to the companies' operating
performance. Specifically, market prices for securities of Internet-related and
technology companies have frequently reached elevated levels following their
initial public offerings. These levels may be unsustainable and may not bear
any relationship to these companies' operating performances. If the market
price of our common stock reaches an elevated level following this offering, it
may materially and rapidly decline. Fluctuations in our common stock's market
price may affect our visibility and credibility in the Internet services
provider market.

  In the past, following periods of volatility in the market price of a
company's securities, stockholders have often instituted securities class
action litigation against the company. If we were to become involved in a class
action suit, it could be costly and divert the attention of management.
Furthermore, if adversely determined, a class action suit may have a material
adverse effect on our business, financial condition and results of operations.

The price per share of our common stock in this offering may not be indicative
of the market price that will prevail after this offering.

  Since our stock has not yet traded publicly, our management and the
underwriters will negotiate the common stock's initial public offering price
per share. The price they determine may not be indicative of the

                                       11
<PAGE>

market price that will prevail after this offering. For example, the market
price of our common stock after this offering could vary from the initial
public offering price in response to any of the following factors, some of
which are beyond our control:

  . changes in earnings estimates or recommendations by analysts

  . future announcements concerning us or our competitors of key personnel
    changes, significant contracts, strategic partnerships, acquisitions,
    technological innovations or capital commitments

  . additions or departures of key personnel

  . quarterly fluctuations in operating results

  . fluctuations in the stock price and volume of traded shares, especially
    in the traditionally volatile Internet-related and technology sectors

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

  Some of the statements under "Prospectus Summary," "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business" and elsewhere in this prospectus constitute forward-
looking statements. Forward-looking statements relate to future events or our
future financial performance. In some cases, you can identify forward-looking
statements by terminology such as "may," "will," "should," "expects," "plans,"
"anticipates," "could," "believes," "estimates," "predicts," "potential" or
"continue" or the negative of these terms or other similar words. These
statements are only predictions. Actual events or results may differ
materially. In evaluating these statements, you should specifically consider
various factors, including the risks outlined under "Risk Factors." These
factors may cause our actual results to differ materially from any forward-
looking statement.

  Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future events or results.

                                USE OF PROCEEDS

  We estimate that the net proceeds from the sale of the     shares of common
stock we are offering will be approximately $    based upon an assumed initial
public offering price of $    per share, after deducting the estimated
underwriting discounts and commissions and estimated offering expenses. If the
underwriters exercise their over-allotment option in full, we estimate that the
net proceeds will be $   .

  We intend to use the net proceeds of this offering for general corporate
purposes, including funding our operations, capital expenditures, network
expansion, working capital and acquisitions of Internet services providers in
our target markets. As part of our growth strategy, we are continually
evaluating, engaging in discussions with and entering into letters of intent
with acquisition candidates. There can be no assurance that any of these
discussions or letters of intent will lead to completed transactions. Until
they are used, the net proceeds of the offering will be invested in short-term
marketable securities.

                                DIVIDEND POLICY

  We have not paid any dividends to date, and we do not anticipate paying any
dividends on any of our common stock in the foreseeable future. We currently
intend to retain all of our earnings, if any, for use in our business. We may
also incur debt in the future which may prohibit or restrict the payment of
dividends.

                                 CAPITALIZATION

  The following table shows our cash and cash equivalents and capitalization on

  . an actual basis as of September 30, 1999

  . a pro forma basis to reflect one of the two acquisitions we made after
    September 30, 1999 as though this acquisition had occurred on September
    30, 1999 and the conversion of our outstanding mandatorily redeemable
    convertible preferred stock on a one-for-one basis into common stock and
    non-voting common stock, which will occur concurrently with the
    completion of this offering

  . a pro forma as adjusted basis to further reflect

   .the sale of the     shares of common stock we are offering at an assumed
    initial public offering price of $    per share, after deducting the
    underwriting fees and estimated offering expenses

   .an increase in the number of our authorized shares of common stock, a
    reduction in the number of our authorized shares of preferred stock and
    elimination of our currently designated series of mandatorily redeemable
    convertible preferred stock from our certificate of incorporation to be
    effected concurrently with this offering.

                                    DILUTION

  Our net tangible book value at September 30, 1999 was $78.4 million, or $1.87
per share of common stock. Net tangible book value per share represents the
amount of total tangible assets less total liabilities, divided by the number
of shares of common stock outstanding.

  Dilution per share to new investors represents the difference between the
amount per share paid by purchasers of common stock in this offering and the
net tangible book value per share of common stock immediately after completion
of this offering. After giving effect to the sale of     shares of common stock
in the offering at an assumed initial public offering price of $    per share
and after deducting underwriting fees and estimated offering expenses, our
adjusted net tangible book value at September 30, 1999 would have been $   , or
$    per share. This represents an immediate increase in tangible book value
per share to existing stockholders of $    and an immediate dilution in
tangible book value per share to new investors purchasing shares in the
offering of $    per share. The following table illustrates this per share
dilution.

      and outstanding as of November 15, 1999 with a weighted average
      exercise price of $6.08 per share. To the extent any of these stock
      options are exercised, there will be further dilution to new
      investors.

                      SELECTED CONSOLIDATED FINANCIAL DATA

  Our selected consolidated statement of operations data for the period from
inception, June 13, 1997, to December 31, 1997 and for the year ended December
31, 1998 and our balance sheet data as of December 31, 1997 and 1998 are
derived from our consolidated financial statements which have been audited by
PricewaterhouseCoopers LLP, independent accountants. Our statement of
operations data for the nine months ended September 30, 1998 and 1999 and our
balance sheet data as of September 30, 1999 are derived from our unaudited
interim financial statements and, in the opinion of our management, include all
material adjustments, consisting only of normal and recurring adjustments
necessary for a fair presentation of the results of operations and financial
condition. Operating results for the nine months ended September 30, 1999 are
not necessarily indicative of the results that may be expected for the full
year.

  As used in the table below, "EBITDA" represents earnings or loss from
operations before interest, taxes, depreciation, amortization and non-cash
stock compensation charges. The primary measure of operating performance is net
earnings. Although EBITDA is a measure commonly used in our industry, it should
not be considered an alternative to net earnings, when determined in accordance
with generally accepted accounting principles or GAAP, as an indicator of
operating performance or as an alternative to cash flows from operating
activities, determined in accordance with GAAP. In addition, the measure of
EBITDA we use may not compare to other, similarly titled measures used by other
companies.

  The selected consolidated financial data and accompanying notes should be
read together with our audited consolidated financial statements, our unaudited
interim financial statements, our acquired companies' financial statements and
related notes, and other financial information including "Management's
Discussion and Analysis of Financial Condition and Results of Operations," all
of which are included elsewhere in this prospectus.

stock. The pro forma balance sheet data as of September 30, 1999 give effect to
our acquisition of InfoAcces and the conversion of all of the outstanding
mandatorily redeemable convertible preferred stock into common stock. The pro

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

  The following discussion and analysis is based on the consolidated historical
results of VIA NET.WORKS, Inc. and the historical results for each of our
operating companies for which separate data have been included in this
prospectus.

Overview

  We are a leading international provider of Internet access and services
focused on small and mid-sized businesses in Europe and Latin America. We have
built our business through the acquisition, integration and growth of 17
Internet services providers in 11 countries, all of which have been acquired
since June 1998. We currently operate in Argentina, Brazil, France, Germany,
Ireland, Mexico, the Netherlands, Portugal, Spain, Switzerland and the United
Kingdom.

  Our financial statements for the period from inception through December 31,
1997 include only corporate expenses. We were a development stage company
during this period and had no revenue-producing operations. Our consolidated
financial statements as of and for the year ended December 31, 1998 include the
results of the four wholly or majority-owned operating companies we acquired
during 1998. These statements also recognize our equity interest in a fifth
operating company, i-way, in which we acquired a minority interest during 1998.
Our consolidated financial statements as of and for the nine months ended
September 30, 1999, include the results of the 14 wholly or majority-owned
operating companies we acquired during 1998 and the first nine months of 1999.
These statements also recognize our equity interest in i-way through August 5,
1999. On that date we purchased the remaining equity in i-way and began
recognizing its results on a consolidated basis.

  We evaluate our business based on our geographic regions. The following table
presents information about our European and Latin American market segments
individually and on a consolidated basis, which includes corporate financial
data, for the years ended December 31, 1997 and December 31, 1998, and for the
nine months ended September 30, 1998 and September 30, 1999.

</TABLE>

  As used in the above table and in the table under "Quarterly Results of
Operations" in this section, "EBITDA" represents earnings or loss from
operations before interest, taxes, depreciation, amortization and non-cash
stock compensation charges. The primary measure of operating performance is net
earnings. Although EBITDA is a measure commonly used in our industry, it should
not be considered an alternative to net earnings, when determined in accordance
with generally accepted accounting principles or GAAP, as an indicator of
operating performance or as an alternative to cash flows from operating
activities, determined in accordance with GAAP. In addition, the measure of
EBITDA we use may not compare to other, similarly titled measures used by other
companies.

                                       21

Revenues

  We generate revenue from the sale of Internet access and value-added
services. Revenue from Internet access services, both dial-up and dedicated,
comes primarily from subscriptions purchased by businesses and consumers. These
subscriptions, most often for three, six or 12-month service periods, are
generally paid for in advance. Larger business customers may be billed monthly
with payment generally being made by direct charge to a credit or debit
account. Additionally, in some countries we receive revenue in the form of
payments from the telecommunications companies that our customers use to access
our services. These providers charge by the minute for both local and long
distance calls, and pay us a portion of the fees they generate from our
customers' Internet use. All of our access revenues are recognized as they are
earned.

  Revenue from Internet value-added services comes from web hosting,
applications hosting, domain name registration, sales, installation and
maintenance of hardware and software, training and consulting and other
services. Services such as web and applications hosting and domain name
registration are often sold on a subscription basis and are paid for in advance
or by monthly direct charges to credit or debit accounts. These revenues are
recognized over the period in which services are provided. Revenues from
hardware and software sales, installation and maintenance, training and
consulting, and other services are usually on a contract basis. These services
are billed periodically and revenues are recognized as they are earned.

  Internet access charges and fees for value-added services vary among our
operating companies, depending on competition, economic and regulatory
environments and other market factors. In some markets, we have reduced prices,
especially for access services, as a result of competitive pressure. We expect
that this pressure will continue in our markets as the demand for, and supply
of, Internet services continue to grow.

Expenses

  Our Internet services operating costs are the costs we incur to carry
customer traffic to and over the Internet. We lease lines that connect our
points of presence, or PoPs, either to our own network or to other network
providers. We pay other network providers for transit, which allows us to
transmit our customers' information to or from the Internet over their
networks. We also pay other recurring telecommunications costs, including the
cost of the local telephone lines our customers use to reach our PoPs and
access our services. We expect that our Internet services operating costs will
increase as we increase capacity to meet customer demand. We anticipate that
these costs will decline as a percentage of revenue, however, as we expand our
owned network facilities and as competition drives the overall price of network
capacity downward.

  Our largest selling, general and administrative expenses are compensation
costs and the costs associated with marketing our products and services.
Compensation costs include salaries and related benefits, commissions and
bonuses. In many of our markets, we are required to make significant mandatory
payments for government-sponsored social welfare programs, and we have little
control over these costs. Our marketing expenses include the costs of direct
mail and other mass marketing programs, advertising, customer communications,
trade show participation, web site management and other promotional costs.
Other selling, general and administrative expenses include the costs of travel,
rent, utilities, insurance and professional fees. We expect that our selling,
general and administrative expenses will increase to support our growth.

  The largest component of our depreciation and amortization expense is the
amortization of the goodwill arising from our acquisitions. Goodwill, which we
amortize over five years, is created when the price at which we acquire a
company exceeds the value of its tangible and intangible assets. We expect
goodwill amortization expense to increase as we make additional acquisitions
and as competition pushes the prices of those acquisitions higher. We also
recognize depreciation expense primarily related to telecommunications
equipment, computers and network infrastructure. We depreciate these assets
over their useful lives, generally ranging from three to five years. Our
network infrastructure is depreciated over 20 or 25 years, depending on the
contract term. We expect depreciation expense to increase as we expand our
network infrastructure and acquire additional operations.

                                       22
<PAGE>

  When applicable, we also recognize interest income and expense, our interest
in an unconsolidated subsidiary and minority interest. We earn interest income
primarily by investing our available cash in short-term treasury securities
funds. To date, this interest income has been partially offset by interest
expense, largely arising from purchase and lease financing in our operating
subsidiaries. Interest in an unconsolidated subsidiary recognizes the value of
our minority investment in i-way. In August 1999 we acquired all the remaining
shares of i-way and began consolidating the results of that subsidiary. For
subsidiaries where we own less than 100% of the equity, minority interest
eliminates a portion of operating results equal to the percentage of equity we
do not own.

  We have recorded deferred stock compensation totaling $1.8 million in
connection with the grant of stock options to employees. This amount represents
the difference between the deemed fair market value of our common stock on the
dates these options were granted and the exercise price of the options. The
amount is included as a reduction of stockholders' equity and is being
amortized over the vesting period of the individual options, generally four
years. For the nine months ended September 30, 1999, we recorded $483,000 in
non-cash, deferred stock compensation charges, leaving $1.3 million to be
recognized over the remaining vesting periods of the stock options. As a
result, we expect to recognize $575,000 in non-cash, deferred stock
compensation charges in the year ending December 31, 1999, $369,000 in the year
ending December 31, 2000, $368,000 in each of the years ending December 31,
2001 and 2002 and $137,000 in the year ending December 31, 2003.

Results of Operations

Nine months ended September 30, 1999 compared with nine months ended September
30, 1998

  Revenue. For the nine months ended September 30, 1999, we had revenue of
$23.4 million. This revenue was generated by the 15 consolidated subsidiaries
that we owned for all or a portion of the period. Of this revenue, 73.7% came
from the sale of Internet access and 26.3% came from the sale of value-added
and other services. Of our value-added and other services revenue, 72.0% came
from web site services including web hosting, web design and domain name
registration. We had no revenue for the nine months ended September 30, 1998 as
we acquired our first consolidated subsidiary on September 24, 1998 and did not
recognize revenue from that operation until October 1998.

  Internet services operating costs. Our Internet services operating costs were
$10.3 million for the nine months ended September 30, 1999. We incurred these
costs primarily to lease lines and purchase transit for the local networks
maintained by the 15 consolidated subsidiaries that we owned for all or a
portion of the period, as well as for operating costs associated with our
international network. We had no Internet services operating costs for the nine
months ended September 30, 1998. We acquired our first consolidated subsidiary
on September 24, 1998 and did not consolidate the results of that operation
until October 1998. Additionally, we did not establish our international
network until June 1999.

  Selling, general and administrative. We incurred selling, general and
administrative expenses of $22.1 million for the nine months ended September
30, 1999, a 673.5% increase over the $2.9 million we incurred for the nine
months ended September 30, 1998. This increase was primarily due to the
addition of costs incurred by the 15 consolidated subsidiaries that we owned
for all or a portion of the 1999 period, but that we did not own for the 1998
period. During the 1999 period, $16.0 million, or 72.3%, of these expenses were
incurred by our local operations and $6.1 million, or 27.7%, were incurred by
our corporate organization. The expenses incurred by our corporate organization
increased by 114.5% between the 1998 and 1999 periods, largely due to the costs
associated with employing a larger number of corporate and regional personnel
and identifying and acquiring an increasing number of operating companies.

  Depreciation and amortization. Our depreciation and amortization expense was
$10.7 million for the nine months ended September 30, 1999, up from $3,000 for
the nine months ended September 30, 1998. This increase was primarily due to
the amortization of goodwill arising from the acquisitions of the 15
consolidated subsidiaries completed between September 24, 1998 and September
30, 1999. The acquisition of these

                                       23
<PAGE>

subsidiaries and the implementation of our international network also increased
our depreciation expense for telecommunications equipment, computers and other
fixed assets. For the 1999 period, $8.1 million, or 76.2%, of our depreciation
and amortization expense was related to the amortization of acquisition
goodwill and $2.6 million, or 23.8% was related to the depreciation of fixed
assets. For the 1998 period, all of this expense was related to the
depreciation of fixed assets.

  Interest income and expense. For the nine months ended September 30, 1999, we
earned $2.3 million in interest income, a 139.8% increase over the $962,000 we
earned for the nine months ended September 30, 1998. Interest income in both
periods was generated primarily from investing funds generated by the sale of
preferred shares until those funds were used for acquisitions, operating
expenses or capital expenditures. We raised $127.9 million in April 1999, $51.6
million in May 1998 and $1.5 million between August 1997 and April 1998 from
these sales. For the 1999 period, we also incurred $974,000 in interest
expense, primarily for purchase and lease financing of equipment in our
operating subsidiaries. We incurred no interest expense for the 1998 period.

  Interest in unconsolidated subsidiary. For the nine months ended September
30, 1999, we recognized a $177,000 loss related to our minority investment in
i-way. This compared to a $447,000 loss recognized for the nine months ended
September 30, 1998 related to the same minority investment. This improvement
was due to i-way's significantly increased revenue and operating results,
largely related to a single contract under which it provides managed bandwidth
for another Internet services provider. In August 1999, we purchased all of the
remaining equity in i-way.

  Foreign currency gains. We recognized a $1.3 million foreign currency gain
for the nine months ended September 30, 1999. In conjunction with some of our
acquisitions, we incurred debts to the acquired companies or their selling
stockholders denominated in foreign currencies. During this period, the U.S.
dollar strengthened relative to these currencies, and the related reduction in
the U.S. dollar value of these debts created a gain. We had no similar debts
for the nine months ended September 30, 1998 and so incurred no foreign
currency gains or losses for the period.

Year ended December 31, 1998 compared with period from inception, June 13,
1997, to December 31, 1997

  Revenue. For the year ended December 31, 1998, we had revenue of $3.3
million. This revenue was generated by the four consolidated subsidiaries that
we owned for all or a portion of the period. We had no operations and therefore
no revenue for the period from inception to December 31, 1997.

  Internet services operating costs. Our Internet services operating costs were
$1.7 million for the year ended December 31, 1998. We incurred these costs to
expand and maintain the network capabilities of the four consolidated
subsidiaries that we owned for all or a portion of the period. We had no
operations and therefore no Internet services operating costs for the period
from inception to December 31, 1997.

  Selling, general and administrative. We incurred selling, general and
administrative expenses of $6.4 million for the year ended December 31, 1998,
up from $336,000 for the period from inception to December 31, 1997. This
increase was due to the addition of costs incurred by the four consolidated
subsidiaries that we owned for a portion of 1998 but that we did not own for
the 1997 period, and for the expansion of our corporate organization. During
1998, $2.0 million, or 31.3%, of these expenses were incurred by our local
operations and $4.4 million, or 68.7%, were incurred by our corporate
organization. All of the costs for the period from inception to December 31,
1997 were incurred in conjunction with the start-up of our corporate
organization.

  Depreciation and amortization. Our depreciation and amortization expense was
$1.3 million for the year ended December 31, 1998. This expense was largely
made up of the amortization of goodwill arising from the acquisition of four
consolidated subsidiaries during 1998, and of depreciation expense for
telecommunications

                                       24
<PAGE>

equipment, computers and other fixed assets in these operations. For 1998,
$936,000, or 71.8%, of our depreciation and amortization expense was related to
the amortization of acquisition goodwill and $368,000, or 28.2% was related to
the depreciation of fixed assets. We had no depreciation and amortization
expense for the period from inception to December 31, 1997.

  Interest income and expense. For the year ended December 31, 1998, we earned
$1.5 million in interest income, up from $15,000 for the period from inception
to December 31, 1997. Interest income in both periods was generated primarily
from investing funds generated by the sale of preferred shares until those
funds were used for operating expenses, capital expenditures or, in 1998,
acquisitions. We raised $51.6 million in May 1998 and $1.5 million between
August 1997 and April 1998 from these sales. For 1999, we also incurred $29,000
in interest expense for purchase and lease financing of equipment in our
operating subsidiaries. We incurred no interest expense for the 1997 period.

  Interest in unconsolidated subsidiary. For the year ended December 31, 1998,
we recognized a $1.2 million loss related to our minority investment in i-way.
We acquired this minority interest in June 1998 and therefore had recognized no
gains or losses for the period from inception to December 31, 1997.

  Foreign currency gains. We recognized a $115,000 foreign currency gain for
the year ended December 31, 1998. In conjunction with some of our acquisitions,
we incurred debts to the acquired companies or their selling stockholders
denominated in foreign currencies. During this period, the U.S. dollar
strengthened relative to these currencies, and the related reduction in the
U.S. dollar value of these debts created a gain. We had no similar debts for
the period from inception to December 31, 1997 and so incurred no foreign
currency gains or losses for the period.

Provision for Income Taxes

  We incurred operating losses from inception through September 30, 1999 and
therefore have not recorded a provision for income taxes. We have recorded a
valuation allowance for the full amount of our net deferred taxes as the future
realization of the net tax benefit is not currently likely.

  As of December 31, 1998, we had U.S. net operating loss carry-forwards of
approximately $1.4 million, which can be used to reduce future taxable income
through 2018. We also had foreign net operating loss carry-forwards of
$406,000, the majority of which will begin to expire in 2003.

Liquidity and Capital Resources

  Since inception, we have financed our operations primarily through the sale
of equity securities. We have raised an aggregate of $181.0 million in three
private preferred stock offerings since August 1997, and at

                                       26
<PAGE>

September 30, 1999, we had cash and cash equivalents of $91.5 million. We used
an additional $38.1 million to acquire InfoAcces and M&Cnet after September 30,
1999. We are pursuing an aggressive internal growth and acquisition strategy
that we anticipate will require significant additional funding before becoming
self-sustaining.

  Net cash used in operating activities was $6.9 million for the nine months
ended September 30, 1999, $3.8 million for the year ended December 31, 1998 and
$233,000 for the period from inception through December 31, 1997. In each
period, cash was primarily used to fund operating losses.

  Net cash used in investing activities was $61.7 million for the nine months
ended September 30, 1999, $14.4 million for the year ended December 31, 1998
and $8,000 for the period from inception through December 31, 1997. For the
nine months ended September 30, 1999 and the year ended December 31, 1998, cash
was primarily used for acquisitions, including, in 1998, our equity investment
in an unconsolidated subsidiary. We also made purchases of property and
equipment in each of the three periods.

  Net cash provided by financing activities was $126.0 million for the nine
months ended September 30, 1999, $52.2 million for the year ended December 31,
1998 and $1.0 million for the period from inception through December 31, 1997.
In each period, cash was primarily generated by the sale of equity securities.

  In conjunction with our acquisition of InfoAcces, we have agreed to pay
additional purchase price consideration of up to $30.0 million based on that
company's revenue growth between the time of acquisition and December 31, 2000.
Additional purchase price, if earned, will be paid quarterly beginning in
February 2000, with the last possible payment date being February 2001. We have
restricted cash of $15.0 million to secure the payment of any additional earned
purchase price. This amount will be reduced as payments are made. Additionally,
in conjunction with the acquisitions of some other operating companies, we have
issued notes to selling shareholders that, at maturity, will be valued at the
greater of principal plus interest or a percentage of the value of the
operating company based on a predetermined formula which considers revenue
growth, operating results and cash flow. As of October 31, 1999, the aggregate
principal amount of these notes outstanding was $7.7 million. Currently, the
principal amount of these notes is, in aggregate, greater than the value that
would be calculated using the formula. We expect, however, that some or all of
these operating companies will achieve results that will increase the value of
these notes and that we will have to recognize and pay additional purchase
price.

  We believe that the proceeds of this offering, together with our cash and
cash equivalents, will be sufficient to fund our operations for the next 12
months. If our internal growth exceeds our expectations, or if we make more or
larger-than-anticipated acquisitions, we may need to raise additional capital
from debt or equity sources. We cannot be sure that we will be able to obtain
this additional financing or that, if we can, the terms will be acceptable to
us. If we cannot obtain additional financing on terms acceptable to us, we may
be forced to curtail our expansion and may be unable to fund our ongoing
operations.

Foreign Currency Exchange Risks

  We conduct business in 11 different currencies. With the exception of the
Argentine Peso, the value of these currencies fluctuates in relation to the
U.S. dollar. At the end of each reporting period, the revenues and expenses of
our operating companies are translated into U.S. dollars using the average
exchange rate for that period, and their assets and liabilities are translated
into U.S. dollars using the exchange rate in effect at the end of that period.
Fluctuations in these exchange rates impact our financial condition, revenues
and results of operations, as reported in U.S. dollars.

  Exchange rates can vary significantly, including exchange rates between Euro-
linked currencies and the U.S. dollar. This is possible because, although these
currencies are linked to the Euro, the exchange rates of these currencies into
U.S. dollars fluctuates independently from the exchange rate of the Euro into
U.S. dollars. During the first nine months of 1999, we experienced exchange
rate fluctuations in the Euro-linked currencies, and particularly in the German
Mark. The Mark varied by 15.2% in relation to the U.S. dollar during this

                                       27
<PAGE>

period, and ended the period 8.7% below where it was nine months earlier. We
also experienced a devaluation of the Brazilian Real in January 1999. The Real
varied by 45.6% in relation to the U.S. dollar during the first nine months of
the year, and ended the period 37.2% below where it began. We also experienced
fluctuations in other exchange rates but they did not have a material impact on
our results.

  Our local operations collect revenues and pay expenses in their home
currencies. They do not have significant assets, liabilities or other accounts
denominated in currencies other than their home currency, and therefore are not
subject to exchange rate risk with respect to their normal operations.

Year 2000 Readiness Disclosure

  Many currently installed computer systems and software products are coded to
accept only two-digit year entries in the date code field. Consequently, on
January 1, 2000, many of theses systems could fail or malfunction because they
may be unable to distinguish 21st century dates from 20th century dates. As a
result, computer systems and software used by many companies, including us, our
suppliers, our customers and our potential customers, may need upgrades to
comply with Year 2000 requirements.

  Internal readiness assessment. The Year 2000, or Y2K, problem may affect the
network infrastructure, computers, software and other equipment that we use,
operate or maintain for our operations. As a result, we have a formal Year 2000
compliance plan, implemented by our internal Y2K task group. This group is
responsible for monitoring the assessment and remediation status of our Year
2000 projects. Under our Year 2000 compliance plan, the Y2K task group has
compiled a listing of all items critical to our operations, both internally
developed and externally purchased, which may be impacted by the Year 2000
problem. We believe that we have identified most of the major computers,
software applications and related equipment used in connection with our
internal operations that will need to be modified, upgraded or replaced to
minimize the possibility of a material disruption to our business. In 1999 we
upgraded our network and operating systems and purchased Year 2000 compliant
servers, workstations, software packages and peripheral devices. As a result of
our upgrades, new purchases and Year 2000 testing, we believe that our
principal internal systems are Year 2000 compliant. However, we will continue
to assess and test our internal systems to ensure that all additions and
modifications to our systems meet our specifications for Year 2000 compliance.
Because we and our customers depend, to a very substantial degree, upon the
proper functioning of our computer systems, a failure of our systems to
correctly recognize dates beyond December 31, 1999 could materially disrupt our
operations and adversely affect our business, financial condition and results
of operations.

  Third-party readiness assessment. We have obtained verification or validation
from most of our independent third-party suppliers whose products and services
are deemed critical to our operations as part of our assessment of any Year
2000 problems we may encounter. We have also obtained verification or
validation from most of our customers concerning Year 2000 compliance. However,
we have limited or no control over the actions of these third-party suppliers
and customers. Thus, while we expect that we will be able to resolve any
significant Year 2000 problems with these third-parties, we cannot be certain
that these business relationships will resolve any or all Year 2000 problems
before the occurrence of a material disruption to our operations. Any failure
of these third-parties to resolve Year 2000 problems with their systems in a
timely manner could significantly harm our business, financial condition and
results of operations.

  Costs. To date, we have funded the costs to become Year 2000 compliant and
have not separately accounted for these costs. These costs have not been
material. We will incur additional costs related to Year 2000 compliance for
administrative personnel to manage the process of remaining Year 2000
compliant.

  Most likely consequences of Year 2000 problems. We expect to identify and
resolve all Year 2000 problems that could significantly harm our business.
However, we believe that the possibility exists that we may experience problems
and costs with Year 2000 compliance which could divert our time and resources
from ordinary business activities and have a material adverse effect on our
business, financial condition and results

                                       28
<PAGE>

of operations. The worst case scenario for Year 2000 problems for us would be
the need to cease normal operations for an indefinite period or time while we
attempt to respond to our Year 2000 problems.

  Contingency plans. We have developed contingency plans to be implemented if
our efforts to identify and correct Year 2000 problems are not effective. We
expect our contingency plans to be ready for implementation by December 31,
1999.

Conversion to the Euro

  On January 1, 1999, 11 of the 15 European Union member countries adopted the
Euro as their common legal currency, at which time their respective individual
currencies became fixed at a rate of exchange to the Euro, and the Euro became
a currency in its own right. Presently, the following 11 currencies are subject
to the Euro conversion: the Austrian Schilling, the Belgian Franc, the Dutch
Guilder, the Finnish Markka, the French Franc, the German Mark, the Irish Punt,
the Italian Lire, the Luxembourg Franc, the Portuguese Escudo and the Spanish
Peseta.

  During a January 1, 1999 until January 1, 2002 transition period, the Euro
will exist in electronic form only and the participating countries' individual
currencies will continue in tangible form as legal tender in fixed
denominations of the Euro. During the transition period, we must manage
transactions with our customers and our third-party vendors in both the Euro
and the participating countries' respective individual currencies. We have
purchased and specified our business support systems, including accounting and
billing, to accommodate Euro transactions and dual currency operations during
the transition period. In addition, we intend to require all vendors supplying
third-party software to us to warrant that their software will be Euro
compliant.

  We conduct business transactions with customers, network suppliers, banks and
other businesses, and we will be exposed to Euro conversion problems in these
third-party systems. During the transition period, to the extent we are
supplying local service, we can continue billings and collections in the
individual currencies to avoid Euro conversion problems. However, to the extent
we have cross-border transactions in European Union countries, we will be
exposed to Euro-related risks. The establishment of the European Monetary Union
may have a significant effect on the economies of the participant countries.
While we believe that the introduction of the Euro will eliminate exchange rate
risks in respect of the currencies of those member states that have adopted the
Euro, there can be no assurance as to the relative strength of the Euro against
other currencies. Since a substantial portion of our net sales will be
denominated in the Euro or currencies of European Union countries, we will be
exposed to that risk.

Quantitative and Qualitative Disclosures about Market Risk

  We are primarily exposed to market rate risk with respect to foreign currency
denominated debt obligations. With the exception of debt incurred in
conjunction with our acquisitions, the substantial majority of our debt
obligations have fixed interest rates and are denominated in the functional
currencies of our various operating companies. As of December 31, 1998 our non-
acquisition debt obligations amounted to $1.1 million. As of December 31, 1998,
we also had notes payable to the selling shareholders of U-Net in the aggregate
principal amount of (Pounds)4.9 million which accrued interest at 7.561% per
annum and were due October 29, 1999. In October 1999, a portion of these notes
was repaid and the remainder, accruing interest at 7.125%, was extended at the
option of each holder. At December 31, 1998 the aggregate carrying amount of
the notes was $8.3 million, which was equal to the approximate fair market
value on that date.

  Our investments are generally fixed rate short-term investment grade and
government securities denominated in U.S. dollars. At December 31, 1998, all of
our investments were due to mature within 12 months and the carrying value of
such investments approximated fair value. We actively monitor the capital and
investing markets in analyzing our capital raising and investing decisions.

Our Markets

  Overview. The rapidly growing demand for Internet access and other value-
added Internet services, coupled with low barriers to entry into the
marketplace, have resulted in a highly fragmented Internet services industry.
There are currently over 8,000 Internet services providers, of which 3,000
operate outside of the United States. We believe small and mid-sized businesses
in our targeted markets are under-served by both large and small Internet
services providers. Large Internet services providers in Europe and Latin
America, which generally focus on Internet access products and rely on indirect
sales, telemarketing and remote customer call centers to serve their customers,
typically lack the local presence needed to provide customized, hands-on
solutions to small and mid-sized business customers. Small, local Internet
services providers in these markets typically cannot provide dedicated, high-
capacity Internet access, round-the-clock support and a complete range of
competitively priced service offerings.

  Market size. The Internet experienced rapid growth in the 1990s and has
emerged as a global medium for communications and commerce. Internet access and
services represent two of the fastest growing segments of the
telecommunications services market. This growth is driven by a number of
factors, including:

  . the large and increasing number of personal computers and other devices,
    in both offices and homes, that are linked to the Internet

                                       30
<PAGE>

  . advances in network design which allow for rapid retrieval of information
    from the Internet

  . increased availability of Internet-based software and applications

  . the emergence of useful content and e-commerce technologies

  . Internet access becoming more widely available, convenient and
    inexpensive

  As shown below, market studies forecast strong growth in Internet services
revenue in our target markets. International Data Corporation, or IDC, predicts
that business Internet services revenues will grow 32.9% annually in Western
Europe from $3.0 billion in 1998 to $12.5 billion in 2003. These revenues come
from the sale of access and value-added services, along with the sale of
network capacity and traffic management services to other Internet service
providers. According to IDC, the greatest growth during this period will occur
in the value-added services area, where revenues are forecasted to increase
from $528 million in 1998 to $3.7 billion in 2003, or 48% annually. IDC also
expects that overall business access revenue growth will remain strong,
averaging nearly 29% annually during the same period.

[A bar graph appears here, showing the projected amount (in billions of
dollars) of Western Europe Business Internet Revenues for Business Access,
Value-Added Services, and Managed Bandwidth Services for each of the years
1998-2003]

  According to a December 1998 Yankee Group study of active Internet accounts,
Internet usage in Latin America grew by 120% in 1998, the highest growth rate
of any region in the world. The region remains one of the world's least
penetrated, with an estimated 15 Internet users for each 1,000 people. The same
study predicts that the number of active Internet access accounts will grow
80.0% annually to 26.4 million in 2002, as Latin American markets become
deregulated, network infrastructure improves and local content becomes more
available. The Yankee Group also estimates that Internet access revenues alone
should increase by 68.2% annually, to $6.0 billion in 2002.

  Business use of the Internet. Businesses initially used the Internet by
establishing web sites to improve internal and external corporate
communications. Today, businesses worldwide increasingly are using the Internet
for critical applications, such as on-line sales and marketing, customer
service, purchasing and project management. The Internet presents a compelling
profit opportunity for businesses by enabling them to reduce operating costs,
access valuable information and reach new markets. Internet access provides a
company with a basic gateway to the Internet, allowing it to use e-mail, access
information, and communicate and conduct transactions with employees, customers
and suppliers. A web site provides a company with an identity and interactive
presence on the Internet, allowing it to post company information and automate
business processes such as sales, order entry and customer service.


                                       31

  In Europe, we have seen the emergence of "free Internet" providers. These
companies offer Internet access at no charge, generating income instead through
revenue sharing arrangements with the local telephone providers. In contrast to
the United States where individuals and businesses typically obtain local
telephone service for flat-rate monthly charges, in Europe and Latin America,
customers generally pay on a per-minute basis. We believe the "free Internet"
providers create an opportunity for us because these providers bring a large
number of new Internet users on-line, which makes it more important for small
and mid-sized businesses to have an Internet presence.

  Our targeted customers recognize the benefit of having a business presence on
the Internet. However, they often do not have the resources to implement and
maintain rapidly changing technologies, create and update content and
communicate with employees, customers and suppliers electronically. Outsourcing
arrangements provide a simple and cost-effective solution to these challenges.

  Effect of deregulation. In recent years, European and Latin American
governments have, to varying degrees, pursued efforts to deregulate and
liberalize their telecommunications markets. These efforts, which include the
gradual opening up of the long-held monopolies of the incumbent national
telephone companies and the gradual reduction of price controls and other
regulatory burdens on market competitors, create an environment which fosters
new entrants and competition.

  The immediate effect of deregulation on the Internet market in these
countries has been improved and expanded network infrastructure for the support
of advanced corporate Internet services. These improvements take the form of
greater numbers of both local dial-up access lines and dedicated, high speed
business lines, as well as improved national and international network
capacity, being made available to business users. Over time, deregulation has
proven to be a catalyst for new entrants to enter the market and not only
compete for the business of the existing customers, but also introduce new
service delivery models, such as cable, digital subscriber line, and broadband
wireless platforms for the delivery of telephone, Internet and multimedia
services.

The VIA Strategy

  Our goal is to become the premier international provider of Internet access
and services to small and mid-sized businesses in Europe and Latin America. We
intend to reach our goal by:

  Maintaining a strong local presence through locally managed operating
companies. In our experience, small and mid-sized businesses generally seek a
provider with locally based personnel who are available to respond to technical
issues, who can assist in developing and implementing effective Internet
solutions and with whom they can establish a long-term relationship. To date,
we have acquired 17 companies in 11 European and Latin American countries. We
targeted these companies based on an overall evaluation of the capabilities of
their management teams, their focus on providing Internet solutions to small
and mid-sized businesses and their history of customer satisfaction. At VIA,
local management teams retain the authority to manage day-to-day operations to
meet the demands of their specific business environments. They also participate
in the development of new products and services so that we can ensure that
customer needs in diverse markets are considered and met.

  Leveraging our brand name and international network. Our high capacity trans-
Atlantic and pan-European network and centralized operations support enable our
local market service providers to compete on a global scale and to provide
their customers international Internet solutions, while retaining their
advantage of quality local service. By linking our operations to our own
European and trans-Atlantic network, we significantly reduce our incremental
data communications costs. In addition, our European and trans-Atlantic network
delivers the high level of Internet services increasingly demanded by
businesses. Because a majority of Internet traffic originating in Europe is
directed through the United States, Internet access from Europe is often
characterized by substantial delays and data loss. Because we can control
congestion on our European and

                                       32
<PAGE>

trans-Atlantic network, we can reduce delays and minimize resultant data loss.
We believe similar economic efficiencies and improvements in overall service
levels will result from the investments we are currently making and planning to
make for upgrades to our local, regional and international network and regional
back office, accounting, billing, and customer care systems.

  By being part of an international Internet services provider, our local
operations gain competitive marketing advantage. The companies we acquire
usually retain their pre-acquisition names and add the VIA name as a co-brand.
Additionally, VIA develops commonly branded products that are offered by our
various operating companies across all of our markets. Over time, and as market
conditions allow, we may convert these local operations exclusively to the VIA
brand.

  Delivering single-source Internet solutions to our customers. We believe that
small and mid-sized businesses are seeking to increase their use of the
Internet as a business tool and are integrating web-based products and services
into their business processes. We intend to capitalize on this trend by
offering a single-source solution to our business customers' Internet products
and services needs. By providing our customers with a single source solution,
we can increase customer satisfaction, reduce customer churn and better
leverage our network infrastructure and sales and marketing resources. We
currently offer a wide range of corporate Internet products and services
designed to respond to these needs and to allow our customers to add additional
services as their needs grow. To provide an easy and cost effective way for our
customers to start and expand their Internet presence, we offer a suite of
bundled corporate Internet services under the Expresso brand. We believe these
products and services will allow us to strengthen our relationships with our
customers and offer them higher margin services.

  The following chart shows how our access and value-added services, both
individually and in bundled service offerings, anticipate the evolving business
Internet needs of our customers. By offering products and services at each step
on this value chain, we can expand our customers' Internet usage, help them
transform their business processes to an Internet platform, and increase our
profitability by selling higher margin services.

  Delivering quality customer service supported by continued investment in
billing, back-office and customer care systems. Our customers will benefit from
our continuing investment in billing, back-office and customer care systems
through quality and responsive customer service. We intend to establish local,
national or regional customer care facilities to provide to all our customers
around-the-clock technical support and customer service. Our goal is to be
recognized by our customers as a provider of quality service.

  Continuing investment in network infrastructure and product development. We
intend to continue to make significant investments to improve and expand our
operating infrastructure. We are upgrading and expanding our network capacity
in each of the 11 countries where we now operate. In Europe, we integrate our
local operating companies' networks into our international network. We plan to
extend this network into Latin America as trans-oceanic and land-based network
capacity becomes commercially available. We are significantly increasing the
web hosting, server co-location, data storage and processing capacities at each
of our operating companies. In many of the countries in which we have local
operations, we are continuing to expand our market opportunities by building
new Internet points of presence in commercial centers in those countries. We
are also in the process of upgrading the customer care and billing facilities
of our local companies, as necessary, and integrating them into regional back
office management information data centers. These infrastructure expansions and
improvements will give us the capacity we need to continue to expand the
services we offer to our current customers and to offer services to additional
customers.

  Accelerating our growth through strategic acquisitions. We intend to continue
to acquire business-focused Internet products and services providers. In
identifying acquisition targets, we seek companies that are run by experienced
managers, are well positioned in their markets and will enhance our portfolio
of products and services. Given the increasingly competitive environment in our
targeted markets and the capital resources required to offer a broad base of
reliable Internet services and accommodate rapid anticipated growth, we believe
that under-capitalized local Internet services providers in our markets will
continue to benefit from combining their operations with ours.

Our Network

  Our European and trans-Atlantic network provides our European operating
companies with high-capacity, redundant Internet Protocol transit. Our network
is connected to the Internet by multiple high-speed fiber connections and by
peering arrangements at major commercial Internet exchanges. Using these
diverse connections, our network dynamically routes traffic over the network of
the provider best able to deliver the data in the most efficient manner. Direct
connections to multiple major carriers and Internet exchanges assure reliable
service levels, protecting against traffic congestion and network outages. We
have designed a redundant network to avoid any single point of failure. Our
Latin American operations are currently connected to the Internet by multiple
leased, high-speed links. We expect to expand our network and network
operations center infrastructure to Latin America as capacity becomes
commercially available.

  Our European operating companies' local networks are connected with our
international network via high-capacity optical transmission media and co-
location of routers. Where co-location is not an option, our operating
companies access our international network through high-speed data
communications facilities. Our European network operations center, which is
located in Germany, is staffed 24 hours a day, 7 days a week, by Internet
systems engineers who are responsible for monitoring the performance of our
network equipment. From this center, we are able to efficiently identify and
correct network problems either remotely or by local dispatch.

  We are currently expanding our network infrastructure by replacing individual
Internet transit arrangements previously entered into by our operating
companies. Our network expansion is designed to offer greater reliability,
improved performance and additional functionality at a lower cost per
transmitted data packet.

  The backbone of our network is made up of two STM-1 fiber optic cable rings,
each providing 155 Mbps of redundant capacity. The first ring provides trans-
Atlantic capacity and connects our New York City and London network nodes. We
acquired a 25-year Indefeasible Right of Use, or IRU, from Global Crossing, an

                                       35
<PAGE>

owner of fiber optic cable systems, in June 1999. Our agreement with Global
Crossing also provides us with the right to acquire additional network capacity
at favorable rates. Global Crossing may suspend services provided to us under
the IRU if we fail to make the required payments or are in a breach of the IRU.

  The second ring provides pan-European capacity and allows us to establish
network nodes in up to seven European cities. We acquired a 20-year IRU from
iaxis, an owner of fiber optic cable systems, in July 1999. The iaxis IRU may
be terminated upon written notice by either party if the other party is in
material breach, or may be terminated or suspended upon the occurrence of
specified events, such as insolvency, bankruptcy or material damage by VIA to
the network. We currently have network nodes in London, Dusseldorf and
Amsterdam and plan to connect a Paris node by the end of 1999 and nodes in
three additional cities during 2000. Future cities we are considering
connecting to this network include Madrid and Geneva.

  In the United States, we have co-located routers at the major public peering
locations in Washington, DC, Palo Alto, Chicago and New York. Our U.S. network
nodes are interconnected through diverse, redundant DS-3, or 45 Mbps capacity,
data communications facilities provided by local telephone companies, inter-
exchange carriers and specialized carriers.

  VIA's network has multiple, redundant connections to Tier 1 Internet transit
providers and major public peering locations in London, Frankfurt and
Amsterdam, where we have co-located routers. A substantial number of our
operating companies have established peering relationships with other local or
regional Internet services providers. In peering relationships, Internet
services providers agree to carry each others' traffic on their networks to
improve performance and reduce congestion and costs. We are in the process of
establishing additional peering relationships with international Internet
services providers. Peering relationships can take the form of either public
peering or private peering. Public peering takes place at a physical location,
usually a network access point, designed for the exchange of Internet traffic
between private Internet services providers. Private peering involves an
agreement between two Internet service providers allowing traffic to pass
between each other's networks at private connection points without having to
traverse the public Internet and public peering points. We are actively
pursuing both private and public peering agreements.

Products and Services

  We currently offer a comprehensive range of bundled and stand-alone Internet
access and value-added products and services. The specific products offered in
each market are determined by the needs of the market and local regulations and
competition. We intend to continue to develop a broad range of innovative and
flexible value-added products and services independently, through acquisitions
and through strategic relationships with key vendors.

  Connectivity services. We offer a variety of connectivity solutions,
including Internet access and third-party software and hardware implementations
and configuration services, which are offered in bundled and stand-alone
packages. Internet access currently includes leased line access and corporate
and consumer dial-up connectivity. We also offer a full range of hardware and
software required to connect to the Internet, including routers, servers,
browsers and other products.

  Value-added services. We believe that our customers will increasingly use the
Internet as a business tool and, as a result, will require an expanding array
of services. We currently offer a wide range of services which provide
additional value to our customers, and we intend to continue expanding our
service offerings through
internal development, acquisitions and strategic relationships with software,
hardware and content providers. We do not currently offer all of these services
in each of our markets. The value-added services we offer include the
following:

  . Web hosting, domain name registration and co-location. Web hosting offers
    business customers a presence on the Internet, enabling them to take
    advantage of the marketing, customer service, internal company
    information, or intranets, and other benefits offered by this presence.
    We currently offer our

                                       36
<PAGE>

   customers web hosting services through Internet data centers located in
   our local operations. The services include the full range of web hosting,
   web design, web site maintenance and ongoing consulting services through a
   combination of internal efforts and the use of independent partners. We
   also offer web site co-location, where a customer-owned web server is
   located at one of our local provider's points of presence, or PoPs, for
   higher reliability. This solution allows the customer to own its own web
   server without having to maintain and manage the data center environment.
   We also intend to implement emerging content distribution technologies
   such as content replication, also known as mirroring, and caching for
   enhanced end user performance. Currently, we have registered over 46,700
   domains and host web sites for 17,000 customers.

  . Virtual private networks, or VPNs. Many companies today use private data
    communication networks, often referred to as wide area networks, or WANs,
    to transfer proprietary data between office locations. These networks are
    built using leased lines from traditional telecom providers. We offer
    companies a less expensive alternative to WANs through VPNs which provide
    secure transmission of private Internet traffic through the Internet.
    Additionally, many companies require that their employees have remote
    access to these private networks from home or while traveling. Through
    our VPN products, we can provide intranet and extranet services.
    Intranets are corporate/organizational networks that rely on Internet-
    based technologies to provide secure links between corporate offices.
    Extranets expand the network to selected business partners through
    secured links on the Internet. Increasingly, companies are finding that
    intranets and extranets can enhance corporate productivity more easily
    and less expensively than proprietary systems.

  . Electronic commerce solutions. Electronic commerce, or e-commerce,
    solutions give businesses the ability to process transactions and perform
    other business functions over the Internet. We provide e-commerce
    solutions that allow our customers to sell products or services directly
    to customers, purchase supplies, coordinate inventory systems with
    suppliers, process electronic payments, track shipments and perform other
    business functions, all in a secure on-line environment. To take full
    advantage of the business opportunity offered by e-commerce, we intend to
    construct additional single-source e-commerce applications and hosting
    environments, making use of our own software development capabilities as
    well as those of third-party software development partners.

  . Security. Security solutions are a vital component for most businesses
    connected to the Internet. Our security solutions provide customers

    .an ability to prevent unauthorized users from accessing its corporate
       network

    .authentication of users attempting to gain access to proprietary or
       confidential information

    .encryption services, providing secured transmission of company data
       through the Internet

  . E-mail. We provide e-mail services that enable our business customers to
    outsource their e-mail requirements and e-mail management to our trained
    systems administrators and support staff. We establish accounts, manage
    the associated mail servers and provide full accessibility to e-mail for
    our customers while saving them the investment in additional servers and
    staff.

  . National and global roaming. We offer the ability for employees of small
    and mid-sized businesses to access their e-mail and the Internet while
    traveling. Currently, many users either cannot do so because of the
    limitations of their local service provider or because they are required
    to pay expensive long distance access charges. We are in the process of
    implementing a global dial-up access roaming product to enable business
    customers to access the Internet locally as they travel throughout their
    countries and abroad.

  . Professional services. Our target customers typically do not have the
    internal resources or personnel to design and maintain Internet services.
    As more businesses use the Internet for mission critical applications, we
    expect they will rely on outside support for many of their information
    technology applications. As a result, we believe it will be increasingly
    important for us to offer onsite, technical

                                       37
<PAGE>

   consulting to customers. Our local providers currently offer a broad range
   of professional services to their customers, including network and system
   design, web content creation, security system needs analysis and
   implementation, virtual private network design and implementation, and
   other Internet-related consulting projects. We intend to invest in
   additional professional services capabilities to provide customers with
   single-source Internet solutions.

  . Enhanced products and services. Customers are increasingly seeking to
    tailor the use of the Internet to their business. We plan to serve these
    needs through the packaging and configuration of third-party
    applications, such as data storage and retrieval, Internet Protocol
    telephony, which permits users to make voice calls on the Internet,
    Internet faxing, Internet audio and video conferencing solutions, and
    other applications that may be developed. As businesses commit to using
    the Internet, we believe that the advanced applications product category
    will continue to expand, offering additional revenue opportunities.

  Bundled Services. To expand market share, increase customer loyalty and
develop strong VIA NET.WORKS brand recognition among the small and mid-sized
businesses in our targeted markets, we are bundling Internet services under a
single brand name, Expresso. We are offering the Expresso suite of products in
each of our markets, with only slight differences in features depending upon
local tariffs and network infrastructure. Our entry-level product, ExpressoWeb,
is designed to give the small and mid-sized business customer a simple, cost
effective way to establish a presence on the Internet. By moving up to our
higher level products, ExpressoNet and ExpressoWay, the same business can
expand its Internet capabilities to meet its increasing needs, without
interrupting its ongoing Internet-based business processes.

  ExpressoNet enables businesses that use local area networks, or LANs, to
route e-mail and other information to users quickly and efficiently while
reducing their call charges and other telecommunications costs. ExpressoWay
offers all of the benefits of ExpressoNet and allows businesses to provide
their employees with Internet access at home or while travelling.

  The features of the various Expresso products generally consist of the
following:

Organization

  We have 17 locally managed operating companies located in 11 countries in
Europe and Latin America. These companies focus on providing a full range of
Internet solutions to small and mid-sized business customers in their local
markets. To best serve the market-specific needs of our target customer base,
each of our operations is staffed with local management, sales, technical and
customer care personnel. Our local managers retain the authority to manage the
day-to-day operations of their businesses, allowing them to establish business
practices, create or customize products and services and develop product
delivery mechanisms that meet the Internet business needs of customers in their
local markets. In every aspect of their relationships with us, our customers
are served in their own language, their own currency and by people who
understand the regulations and business practices in the markets in which they
operate. We believe that by maintaining this type of presence within each of
our markets, we are in the best position to understand, and provide solutions
for, the Internet needs of our customers. The following table summarizes our
operations in Europe and Latin America by country, operating company and
percentage ownership. Ecce Terram and INS are each 100% owned by GTN, which is
51% owned by us.

  We have agreements with the minority stockholders of each of our majority-
owned operating companies that give us the right to purchase their shares in
those operating companies based on predetermined price formulas which consider
revenue growth, operating results and cash flows. In some cases, the minority
stockholders have the right to purchase our shares in those operating companies
if we do not exercise our purchase right by a specified date.

  Regional operating, marketing and financial personnel, hired in the regions
they serve, support our local operations. In both Europe and Latin America, a
Regional Vice President is responsible for monitoring the results of,
coordinating efforts among, and assisting in the operations of our local
operating companies. In Europe, regional marketing personnel develop products
for regional deployment, create marketing and advertising programs to promote
cross-market brand recognition and assist our operating managers with local
product, marketing and sales efforts. European financial personnel assist our
local operating companies with financial reporting, budget preparation and the
implementation of proper financial policies, procedures and controls. We are
currently recruiting similar regional marketing and financial positions to
support our Latin American operations.

  We maintain a small corporate staff, located in Reston, Virginia, to perform
and coordinate company-wide activities. These activities include raising
capital and managing its deployment to fund growth, creating and implementing
international network and management information systems, acquiring additional
operating companies in our target markets and creating strategic vendor,
product and service relationships. We intend to keep our corporate staff small,
performing as many functions as possible within the local operating companies
and the regions.

Sales and Marketing

  We sell our products and services through local sales efforts, supported by
local, regional and international advertising and promotion programs. Our
direct sales and marketing force of 237 locally based, technically competent
and experienced Internet sales representatives is our primary sales tool, but
we also maintain significant distribution capabilities through local reseller
and referral channels. We will continue to expand both our direct and indirect
sales capabilities, as well as develop new product and strategic relationships
to support those efforts.

  Direct sales. Each of our local operating companies has a direct sales force.
Depending on the market, the local sales force may include both telemarketing
and field representatives. Typically, telemarketing representatives, both
inbound and outbound, handle sales of basic services, where consulting,
customization or training is not required. Field sales representatives handle
sales of more complex services. Our field representatives are technically
proficient Internet specialists who understand the environment in which their
customers do business and who can create or tailor Internet solutions to meet
customer and market specific needs.

  Our local operating companies maintain customer and prospect data that is
used to identify likely users of existing and new services. They also maintain
competitive data that is used to identify areas of opportunity for new products
and services. Depending on the accepted practices and regulations in their
markets, our operating companies may use techniques such as direct mail or fax,
outbound telemarketing, seminars and trade shows to target large potential
customer groups that they believe would benefit from our Internet business
applications and services.

  Indirect sales. In many of our markets, indirect sales channels represent a
significant source of revenue and revenue growth. Currently, our operating
companies have various indirect sales channels within their markets. These
include reseller and distributor relationships with systems integrators, value-
added resellers, marketers of other subscription-based products and others who
have established relationships with our target customers and sales forces
capable of selling Internet services. Our operating companies also maintain
relationships with referral partners, such as web designers or advertising
agencies, whose core businesses typically do not include providing Internet
services, but who represent a valuable source of leads.

                                       40
<PAGE>

  We are also developing company-wide reseller and referral programs that will
permit us to increase the number of indirect sales channels available to our
operating companies. We will also use these programs to expand the
relationships our local operating companies currently have to a regional or
international basis.

  New products and strategic marketing relationships. To support our local
direct and indirect sales efforts, we are developing strategic relationships
with providers of related technology, products and services, for use in all of
our markets. These relationships will allow our operating companies to offer an
expanded range of Internet services to their customers by giving them access to
new stand-alone or bundled solutions. Our first agreement is with Trellix
Corporation, under which we both resell their web development software on a
stand-alone basis and bundle it into our Expresso products in some of our
markets. By bundling our services with those of related product and service
providers, we believe that we can not only provide expanded services to our
customers, but strengthen our relationship with them as well.

Competition

  Competition in the market for Internet access and value-added services has
increased significantly in our markets as Internet usage has grown, and we
expect this trend to continue. Though Internet usage remains lower in Europe
and Latin America than in more mature markets such as the United States, high
recent growth rates and large potential market sizes have attracted many new
entrants. Though our specific competitors vary from market to market, they
generally are international, regional and local Internet services providers,
long distance and local exchange telecommunications companies, cable television
companies or on-line services providers.

  Internet services providers. According to Boardwatch magazine, there are over
8,000 Internet services providers worldwide with approximately 3,000 of those
located outside of the United States. Depending on the market, our primary
competitors may be small, local services providers with limited ranges of
service and geographic reach, or large international or regional services
providers with broad services offerings, large network capacities and wide
geographic presence. The small, local providers often focus on consumer dial-up
Internet access and frequently do not have the services or expertise to assist
small and mid-sized businesses in establishing a presence on the Internet or
creating an Internet platform to support their business processes. The large
international and regional providers also often focus on consumer dial-up
Internet access. While these large Internet services providers may have the
range of services required to meet the needs of small and mid-sized businesses,
they may not have the local personnel and market expertise to effectively
implement solutions for this customer base. By combining local market expertise
and service with an international network and a wide range of services targeted
towards small and mid-sized business customers, we believe we can compete
effectively with both large and small Internet services providers.

  Telecommunications companies. Many of the major international
telecommunications companies offer Internet services in our markets, either
directly or through subsidiaries or alliances. In several of our markets,
former telecommunications monopolies have been deregulated and privatized, and
have also become providers of Internet services. New telecommunications company
entrants to these markets are beginning to use high-speed wireless technology
to bypass overcrowded, existing networks and are offering Internet and
corporate data services as well. Generally, these network-based companies focus
on consumer dial-up Internet access and large corporate accounts, customer
bases that can generate high volume data traffic to carry on their networks. We
believe that our focus on providing products and services that meet the
Internet needs of small and mid-sized businesses will allow us to compete
effectively with telecommunications company competitors.

  Cable television companies. Cable operators in some of our markets have
either introduced or announced that they intend to introduce Internet access
services, both by upgrading their networks and using new, cable modem
technology. Their existing customers are primarily residential and their
physical networks are largely limited to residential areas. We therefore expect
these companies to present relatively little competition for small and mid-
sized business customers in our markets.

                                       41
<PAGE>

  On-line service providers. We compete with large on-line and portal services
providers in Europe and Latin America. These on-line services providers
generally have business models which rely on consumer dial-up access and
advertising revenue.


Regulatory Matters

  There exists no uniform body of law in Europe or Latin America specific to
the regulation of Internet services or Internet services providers. However,
many local laws which are not specific to Internet services and use of the
Internet apply to the provision of our services generally. As a new and
important medium for communication and business transactions, the Internet is
undergoing considerable legal and regulatory scrutiny worldwide. New laws and
regulations regarding the Internet have been proposed or are currently being
considered in many countries in which we operate, covering issues such as user
privacy and information security, obscenity and child protection, defamation,
taxation, and intellectual property rights. At the same time, the application
of existing laws to communications and the transaction of business through the
Internet are being clarified and refined. We cannot predict what impact future
judicial, legislative or regulatory changes will have on the industry in
general or our operating results specifically, or whether local regulatory
bodies will question our compliance with applicable regulations.

  For example, due to the global nature of the Internet, it is possible that,
although the equipment and software used to provide our services is based in
Europe or Latin America and transmission by us and our users of content over
the Internet would originate primarily in these regions, the governments of
countries in other regions might attempt to regulate the content contained on
or transmitted using our services or prosecute us for violations of their laws.
As content produced by us or our users is available over the Internet in
countries all around the world, these countries may also claim that we are
required to qualify to do business in their jurisdictions. Any application of
existing laws and regulations from jurisdictions whose laws do not currently
apply to our business, or the application of existing laws and regulations to
the Internet and other online services, could have a material adverse effect on
our business, results of operations and financial condition.

  Further, future regulatory developments might decrease the growth of the
Internet, impose taxes or other costly technical requirements, create
uncertainty in the market or in some other manner have a material adverse
effect on our business, financial conditions or results of operations.

  The regulatory framework in each of the two major markets in which we provide
services is described further below.

 European Union

  Overview. Our European operations, other than in Switzerland, are all located
in member countries of the European Union. Within the European Union, the
European Commission, in coordination with the Council of Ministers, can enact
legislation that is enforceable in each of the member states. It is rare,
however, for the European Commission to take legislative action directly.
Instead, it typically adopts "directives" which require member states to enact
laws within their own countries implementing the principles and rules
established by the directive.

  Data Protection. In October 1995, the European Union adopted the "directive
on the protection of individuals with regard to the processing of personal data
and the free movement of such data." This directive imposes restrictions on the
collection, use and processing of personal data. Member states of the European
Union were required to implement the directive into national laws by October
24, 1998, but many of them, including the Netherlands, France, Germany and
Ireland, have yet to do so. In these countries, however, there is prior
legislation that deals with the protection of personal information in varying
degrees.

  The data protection directive is intended to permit the free-flow of personal
information among member states, but also prohibit the transfer of such
information to countries outside the European Union that do not maintain
adequate standards of privacy and data protection. Currently, the European
Union considers the United

                                       42
<PAGE>

States to not have an adequate level of protection in relation to the
processing of personal data. Therefore, except under limited circumstances, we
would not be permitted to cause any of our operations located within European
Union member states to transfer their customers' or employees' personal
information to the United States, including to our Reston, Virginia
headquarters. We cannot predict how the current difference between the United
States and the European Union regarding data protection will be resolved, or
what impact the directive may have on our operations and our effective use of
data collection. In addition, until specific implementing legislation is
enacted in the member states in which we operate, it is unclear how our
operations might be impacted by restrictions that might be established in each
European Union country with respect to the use of personal information about
our customers and employees that we collect in the ordinary course of business.

  Content Regulation and Liability. While there currently are no specific laws
within European Union member states governing liability of Internet services
providers for the content transmitted from or stored on their facilities,
courts in several countries have recognized the general principle that Internet
services providers should not be responsible for content created or maintained
by a third party which the provider makes available to users unless the
provider has knowledge of such content and is technically able and can
reasonably be expected to block the use of such content.

  In November 1998, the European Union published a "proposed directive on
certain legal aspects of electronic commerce in the Internet Market." The draft
of the proposed directive is expected to be adopted by the beginning of 2000
and implemented within one year by all European Union member states. The
proposed directive provides that Internet services providers would not be
liable for any information hosted unless the Internet services provider knew
that the information hosted was illegal. In addition, the proposed directive
provides that Internet services providers, as mere carriers of information
over, or providers of access to, communications networks will not be liable for
the content of that information.

  On December 21, 1998 the European Union approved an "action plan to promote
safer use of the Internet by combating illegal and harmful content on global
networks." This directive would serve as the basis of new laws in member states
relating to the protection of minors, rating and filtering systems and content.
Any legislation that is adopted by European Union member states relating to
this directive could impose additional obligations and expenses on our
operations.

  Licensing Requirements. In the United Kingdom, the Telecommunications Act of
1984 provides that it is a criminal offense to run a telecommunications system
without a license. While Internet services providers fall within a class
license called the Telecommunications Services License and are not required to
hold individual licenses under the Telecommunications Act, we own and operate
our own network facilities in the UK connecting our trans-Atlantic backbone to
connection points in the city of London. Accordingly, we have acquired an
individual public telecommunications operator license issued under the
Telecommunications Act 1984. Under our license, we are legally permitted to
negotiate for direct interconnection with British Telecom and other licensed
network operators in the United Kingdom. Our license also imposes conditions on
us, including the obligation to provide, at our cost, the technical means for
authorized government agencies to intercept communications traffic on our
network within the United Kingdom. If we were to fail to continue to satisfy in
any material respect the conditions on which we hold our license, we would not
be permitted to operate our trans-Atlantic 155 Mbs network within the United
Kingdom, which would have a materially adverse effect on our operations.

 Latin America

  In all Latin America markets in which we currently operate, the provision of
Internet access and value-added services, with the exception of Internet
telephony, is completely deregulated, and companies may satisfy all the
licensing requirements necessary to become an authorized provider of Internet
access and value-added services by obtaining a value-added services license.
All of our Latin American local providers possess these licenses.

                                       43
<PAGE>

  In each of the countries in Latin America in which we are operating, there
are restrictions against the provision of basic, public telephony services over
the Internet by companies other than the licensed basic services providers. The
provision of private corporate network Internet telephony services remains a
gray area. We do not intend to offer either public or private Internet
telephony services in these countries until the respective regulatory
authorities explicitly permit Internet services providers to do so.

  As in Europe, Latin American countries in which we operate are considering
specific legislation with respect to the Internet, covering issues such as user
privacy, obscenity, libel, child protection, taxation, advertising,
intellectual property rights, and information security.

  Our Brazilian local operating company, Dialdata, is located in the state of
Sao Paulo, which levies a 25% sales tax on communication services. The question
of whether providing access to the Internet is a communication service has not
been addressed by the courts or tax authorities in Brazil. Dialdata does not
charge this tax to its customers or pay it to the state tax authority. If
Internet access providers are ultimately required to pay the tax, our operating
results in Brazil would be significantly and negatively impacted.

  In Mexico, the Federal Telecommunications Law prohibits Internet services
providers from building and operating a public telecommunications network or
national satellite connection without first obtaining a concession. Under the
concession scheme, non-Mexican ownership of the concession holder may not
exceed 49%. As a result in Mexico, we will not be able to own our own network
facilities without partnering with a Mexican company or person.

Legal Proceedings

  We are not a party to any material legal proceedings.

Employees

  At October 31, 1999, we employed 798 people on a full-time equivalent basis.
26 employees were located in our Reston, Virginia headquarters and 772 were
located in our local operating companies or European and Latin American
regional offices. Of our total employees, 237 were involved in sales and
marketing, 107 were employed in customer care, 241 were involved in technical
and engineering and the remaining 213 were devoted to finance, legal, strategic
planning and other administrative functions. Relations with our employees are
good. Some of our operating companies in Latin America are parties to
collective bargaining agreements.

  Labor laws in Europe and Latin America are generally more protective of
employees than in the United States. Unlike in the United States where an
employer will often have the right to terminate an employee at will, most
countries in Europe and Latin America have laws protecting employees from being
terminated without proper cause or without paying terminated employees
severance compensation in established statutory amounts. In some European
countries, the law establishes a minimum number of vacation days. In Argentina,
Brazil and Spain, employees are entitled to an additional month's salary each
year as a compulsory bonus. In Portugal, employees are entitled to two
additional months' salary, a summer bonus and a winter holiday vacation bonus.
In Mexico and Brazil, profit-sharing with employees is mandatory.

Facilities

  Our principal executive offices are located in leased facilities at 12100
Sunset Hills Road, Reston, Virginia. Additionally, we lease space in our
operating markets for offices, network operations centers, data centers and
points of presence. We believe that our present facilities are in good
condition and are currently suitable for our business needs. We anticipate that
we will need additional space, particularly in our operating markets, as we
expand, and that we will be able to obtain suitable space where and as needed.

Board of Directors

  Our board of directors is authorized to have up to ten members and we
currently have nine. Directors each serve for a one-year term.

Committees of the Board of Directors

  Our board of directors has established an audit committee, a compensation
committee, a finance committee and a nominating committee.

  Among other functions, the audit committee

  . nominates independent auditors for approval by our stockholders

  . reviews the scope, results and costs of the audit with our independent
    auditors

  . reviews our financial statements

  . reviews and evaluates our internal control practices

  The members of the audit committee are Mr. Torgerson, who is Chairman, and
Messrs. Puente and Eley.

  The compensation committee is responsible for administering our 1998 Stock
Option and Restricted Stock Plan and our Key Employee Equity Plan, both of
which are described below, and for reviewing and approving all compensation
arrangements for our officers. The members of the compensation committee are
Mr. Puente, who is Chairman, and Messrs. Battista and Goldman.

  The finance committee is responsible for reviewing and making recommendations
on proposed debt and equity financings. The members of the finance committee
are Mr. Elsner, who is Chairman, and Messrs. Goldman, Johnston and Masiello.

  The nominating committee is responsible for identifying, evaluating and
recommending individuals for membership on our board of directors and its
committees. The members of the nominating committee are Mr. Battista, who is
Chairman, and Messrs. D'Ottavio, Eley and Elsner.

  None of the members of the audit committee or the compensation committee
performs the same function for any other entity whose executive officers serve
on our board of directors.

Limitation of Liability and Indemnification Matters

  We have adopted provisions in our amended and restated certificate of
incorporation which provide that our directors shall not be liable for monetary
damages to us or our stockholders for any breach of fiduciary duties to the
fullest extent permitted by Delaware law. Such limitation of liability does not
affect the availability of equitable remedies such as injunctive relief or
rescission.

  In addition, our certificate of incorporation and by-laws require us to
indemnify our directors and officers to the fullest extent permitted by
Delaware law. At present, we are not aware of any pending or threatened
material litigation or proceeding involving any director or officer where
indemnification will be required or permitted. We believe that these provisions
in our certificate of incorporation and bylaws are necessary to attract and
retain qualified persons as directors and officers.

  Option Grants in Last Fiscal Year. The following table provides information
relating to options to purchase common stock we granted our named executive
officers during the year ended December 31, 1998. The percentages in the table
below are based on the options to purchase shares of our common stock we
granted under our 1998 Stock Option and Restricted Stock Plan in the year ended
December 31, 1998. The options described in the table below become exercisable
over a period of four years and have a term of ten years. 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 our 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 rates 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 estimates of future stock price growth.

  Option Exercises and Fiscal Year-End Option Values. The table below presents
summary information with respect to stock options owned by our named executive
officers at December 31, 1998, none of whom exercised stock options in 1998. We
have calculated the value of unexercised in-the-money options based on our
determination that the fair value of our common stock on December 31, 1998 was
$2.40 per share. We determined this value on a basis consistent with the method
we used to price shares of preferred stock we sold to our investors.

Key Employee Equity Plan

  In 1998, we adopted the Key Employee Equity Plan to attract and retain
qualified officers, key employees, directors and other persons at VIA and our
operating companies by granting them the right to purchase shares of our common
stock. Typically, purchase rights under this plan are fully vested on the date
of the grant and expire two months from the date of the grant unless earlier
terminated.

  A total of 800,000 shares have been reserved for issuance under our Key
Employee Equity Plan, of which 445,158 have been issued and are currently
outstanding, and an additional 5,000 are subject to outstanding purchase
rights, as of the date of this prospectus.

  Our compensation committee, which administers the Key Employee Equity Plan,
has full power and final authority to designate the grantees, to determine the
number of purchase rights awarded, and to determine the terms and conditions
relating to the vesting, exercise, transfer or forfeiture of the grant,
including the exercise price. Upon termination of a grantee's employment or
other relationship with us, any unexercised purchase rights held by the grantee
terminate immediately.

1998 Stock Option and Restricted Stock Plan

  We have adopted the 1998 Stock Option and Restricted Stock Plan, which allows
us to issue restricted shares of our common stock or options to purchase shares
of our common stock. The total number of shares of our common stock available
for issuance under the 1998 plan is 9,200,000, no more than 125,000 of which
may be issued in the form of restricted common stock. No person may be granted
more than 125,000 shares of restricted stock or options to purchase more than
400,000 shares of stock in any calendar year.

  The 1998 plan is administered by the compensation committee. Except as
described in the plan, our compensation committee determines the grantees, the
type of grant, number of shares subject to each grant, and the term, exercise
price, and vesting schedules for each grant. All of our employees are eligible
to participate under the 1998 plan. The maximum term of options granted under
the 1998 plan is ten years.

  As of the date of this prospectus, options to purchase 4,622,500 shares of
common stock have been issued and are outstanding under the 1998 plan. All of
these options are subject to vesting requirements based on continued
employment, typically vesting over two to four years, and have an exercise
price equal to what the board determined the fair market value of the common
stock to be on the date of the grant.

Employment Agreements

  We have entered into an agreement with Mr. Kenneth Blackman under which he
receives an annual salary of approximately $160,000, is eligible to receive an
annual bonus of up to 50% of his annual base salary and is entitled to other
specified benefits. In addition, Mr. Blackman is entitled to receive 12 months'
notice prior to termination until June 22, 2000 and six months' notice after
June 22, 2000.

  We also have entered into an agreement with Mr. Antonio Tavares under which
he became one of our executive officers. This agreement entitles Mr. Tavares to
receive an annual bonus of up to 60% of his base annual salary through December
31, 1999. Beginning January 1, 2000, Mr. Tavares' maximum annual bonus will be
50% of his base annual salary.

Compensation of Directors

  During fiscal year 1998, our directors were not compensated for serving as
members of the board of directors. Beginning in 1999, each of our independent
directors who is not an employee of VIA or a board designee of one of our
preferred stockholders receives an annual fee of $5,000 for serving on our
board, plus a $1,000 fee for each regularly scheduled meeting he or she attends
and a $500 fee for each special meeting and each committee meeting he or she
attends. In addition, each of these directors, upon joining our board, receives
an option to purchase 100,000 shares of our common stock at an exercise price
equal to the fair market value of the stock on the date of grant. Currently
Messrs. Battista and Puente are our only directors who have received this
compensation. During fiscal year 1999, Mr. Battista also received and exercised
the right to purchase 50,000 shares of our common stock under our Key Employee
Equity Plan at a per share price of $4.00. All of our directors are reimbursed
for travel and other expenses relating to attendance at meetings of the board
of directors or committees of the board of directors.

  Stockholders Agreement. We entered into a stockholders agreement with the
purchasers of our preferred stock. As amended in April 1999, this agreement
gives each of the following stockholders the right to designate one director to
our board: Providence Equity Partners, L.P., BCI Growth V, LLC, Norwest Equity
Partners, LLC, Centennial Fund VI, L.P., Telecom Partners II, L.P., Verio Inc.
and HarbourVest International Private Equity Partners III-Direct Fund L.P. The
stockholders agreement also gives our preferred stockholders a right of first
refusal to purchase some or all of the shares of stock that are proposed to be
sold by us, by some of our officers or by other preferred stockholders. In the
context of our initial public offering, the stockholders agreement gives our
preferred stockholders the right to purchase in the aggregate up to 5% of the
shares of stock sold in the offering. All of these rights will terminate upon
the closing of this offering.

  The stockholders agreement also gives our preferred stockholders the right to
require us to register their shares of common stock for resale and to pay the
expenses of registering their shares. These registration rights will continue
until 2009, but will terminate early for any stockholder whose shares may be
sold under Rule 144(k) under the Securities Act, so long as that stockholder
holds less than 2% of our then outstanding shares of common stock.

  Registration Rights. We have entered into a registration rights agreement
with some purchasers of our common stock, including Mr. Blackman. Under this
agreement, if at any time after our initial public offering we decide to
register shares of our common stock for our own account or for the account of
other stockholders, then our stockholders who are parties to the registration
rights agreement may require us to register their shares of common stock as
well. We are obligated to pay all expenses incurred in connection with
registering shares of common stock under the registration rights agreement.

Options and Warrants

  The table below shows information about stock options we have granted to our
directors and executive officers that have a value in excess of $60,000, based
on the difference between the option exercise price per share and the value of
the underlying stock on the date of grant. Each of these options is subject to
vesting based on the grantee's continued employment or service as a director
and vests over a period of three or four years from the date of grant.

  In April 1998 we issued a warrant to Steven C. Halstedt, who at the time was
a director of VIA, to purchase 100,000 shares of our common stock at a per
share price of $2.40. The warrant, which was exercisable upon issuance and has
a term of five years, was issued in consideration of Mr. Halstedt's services to
VIA as acting president. Centennial Fund V, L.P., of which Mr. Halstedt is a
principal, and which holds more than 5% of our outstanding stock, has informed
us that it is entitled to the economic benefit of this warrant under the terms
of its partnership agreement.

Acquisitions of Dialdata and WorldWide Web Services

  In December 1998, we purchased stock totaling 51% of the outstanding stock of
Dialdata S.A. Internet Systems, located in Brazil, from Dialdata and from some
of Dialdata's shareholders. In exchange for the shares we purchased from
Dialdata, we paid $1.4 million in cash and $4.1 million in notes bearing
interest at an annual rate of 4% and payable in ten equal monthly installments,
the last of which we paid in October 1999. Mr. Antonio Tavares, a co-founder of
Dialdata who owned 35.7% of Dialdata prior to our acquisition and 19.2% after
our acquisition, became one of our executive officers after our acquisition of
Dialdata. As part of our acquisition, Mr. Tavares also sold us shares of stock
in Dialdata for $960,000 in cash. In July 1999, we acquired additional shares
representing 2.3% of Dialdata's stock from Mr. Tavares in exchange for 35,000
shares of VIA common stock.

  In May 1999, we acquired all of the outstanding stock of WorldWide Web
Services, Inc., located in the United Kingdom, for $7.3 million in cash and
promissory notes, which bore interest at an annual rate of 5%. We paid off the
entire outstanding balance due under the notes in September 1999. Mr. Kenneth
Blackman owned 23.0% of WorldWide Web Services prior to our acquisition of the
company. Mr. Blackman became one of our executive officers subsequent to our
acquisition of WorldWide Web Services.

  Our acquisitions of Dialdata and WorldWide Web Services were each consummated
in the local currency for these companies. As a result, the dollar amounts
stated above are based on the exchange rates we used to make these
calculations.

                          DESCRIPTION OF CAPITAL STOCK

General

  Until the closing of this offering, our authorized capital stock will consist
of 57,000,000 shares of common stock, par value $0.001 per share, 7,500,000
shares of non-voting common stock, par value $0.001 per share, and 48,800,000
shares of preferred stock, par value $0.001 per share. As of November 15, 1999,
there were 1,957,671 shares of common stock outstanding and 39,993,650 shares
of mandatorily redeemable convertible preferred stock outstanding which will
convert into 33,223,649 shares of common stock and 6,770,001 shares of non-
voting common stock concurrently with the closing of this offering. Our
outstanding shares were held by 66 stockholders of record. In addition, as of
November 15, 1999 there were outstanding stock options to purchase a total of
4,622,500 shares of common stock at a weighted average exercise price of $6.08
per share, a warrant to purchase a total of 100,000 shares of common stock at
an exercise price of $2.40 per share and a right to purchase 5,000 shares of
common stock for $8.25 per share.

  Following this offering, based on the number of shares of common and
mandatorily redeemable convertible preferred stock outstanding on November 15,
1999, we will have outstanding    shares of common stock and 6,770,001 shares
of non-voting common stock.

  Upon the closing of this offering, our certificate of incorporation will be
amended and restated to include the following provisions:

Common Stock

  We will be authorized to issue 100,000,000 shares of common stock and
7,500,000 shares of non-voting common stock. Each stockholder of record will be
entitled to one vote for each outstanding share of our common stock owned by
that stockholder on every matter properly submitted to the stockholders for
their vote. Holders of non-voting common stock will not be entitled to vote
except as required by law, and each share of non-voting common stock will be
convertible into one share of common stock at the holder's option at any time.
In all other respects, the rights of the non-voting common stock will be the
same as those of the common stock. After satisfaction of the dividend rights of
holders of preferred stock, holders of common stock are entitled to any
dividend declared by the board of directors out of funds legally available for
this purpose, and, after the payment of liquidation preferences to holders of
preferred stock, holders of common stock are entitled to receive, on a pro rata
basis, all our remaining assets available for distribution to the stockholders
in the event of our liquidation, dissolution or winding up. Holders of common
stock do not have any preemptive right to become subscribers or purchasers of
additional shares of any class of our capital stock. The outstanding shares of
common stock are, and the shares of common stock offered in this offering will
be, when issued and paid for, fully paid and non-assessable. The rights,
preferences and privileges of holders of common stock may be adversely affected
by the rights of the holders of shares of any series of preferred stock that we
may designate and issue in the future.

Preferred Stock

  Our certificate of incorporation will allow us to issue without stockholder
approval preferred stock having rights senior to those of the common stock. Our
board of directors will be authorized, without further stockholder approval, to
issue up to 10,000,000 shares of preferred stock in one or more series and to
fix the rights, preferences, privileges and restrictions of any series of
preferred stock, including dividend rights, conversion rights, voting rights,
terms of redemption and liquidation preferences and to fix the number of shares
constituting any series and the designations of these series.

  Our issuance of preferred stock may have the effect of delaying or preventing
a change in control. Our issuance of preferred stock could decrease the amount
of earnings and assets available for distribution to the holders of common
stock or could adversely affect the rights and powers, including voting rights,
of the holders of common stock. The issuance of preferred stock could also have
the effect of decreasing the market price of the common stock.

  The transfer agent and registrar for our common stock is    .

Listing

  We intend to apply to have our common stock approved for quotation on the
Nasdaq National Market under the trading symbol "VNWI."

                        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, we will have outstanding     shares of our common stock and
6,770,001 shares of our non-voting common stock, assuming no exercise of the
underwriters' over-allotment option and no exercise of outstanding options.
Because each share of non-voting common stock may be converted into one share
of common stock at the holder's option, information in this section assumes the
conversion of each share of non-voting common stock into one share of common
stock. 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 "affiliates" of VIA as that term is defined
in Rule 144 under the Securities Act.

  The remaining 41,951,321 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. The
provisions of Rules 144 and 701 provide that the restricted securities will be
available for sale in the public market on the date which is one year from the
date they were issued and fully paid for, so long as the sellers of restricted
securities comply with the volume limitations and other conditions of Rule 144.

Rule 144

  Under Rule 40,652,810 shares of common stock will be freely tradable 90 days
after this offering closes. Sales of some of these shares of common stock will
be limited under lock-up agreements with the underwriters. 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:

  . 1% 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 that sale.

  Sales under Rule 144 are also governed by manner of sale provisions and
notice requirements, and current public information about VIA must be
available.

  Under Rule 144(k), an additional 225,000 shares of common stock will be
freely tradable after this offering closes. Some of these shares of common
stock will be restricted from sale under lock-up agreements. 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.

   MATERIAL FEDERAL INCOME TAX CONSEQUENCES TO NON-UNITED STATES STOCKHOLDERS

  This is a general summary of material United States federal income and estate
tax considerations with respect to your acquisition, ownership and disposition
of common stock if you are a holder other than:

  .  a citizen or resident of the United States

  .  a corporation, partnership or other entity created or organized in, or
     under the laws of, the United States or of any political subdivision of
     the United States

  .  an estate, the income of which is subject to United States federal
     income taxation regardless of its source

  .  a trust, if a court within the United States is able to exercise primary
     supervision over the administration of the trust and one or more United
     States persons have the authority to control all substantial decisions
     of the trust or

  .  a trust that existed on August 20, 1996 and elected to be treated as a
     domestic trust as of that date

  This summary does not address all United States federal income and estate tax
considerations that may be relevant to you in light of your particular
circumstances or if you are a holder subject to special treatment under United
States income tax laws, such as insurance companies, tax-exempt organizations,
financial institutions, brokers, dealers in securities, and certain U.S.
expatriates. This summary does not discuss any aspects of state, local or non-
United States taxation. This summary is based on current provisions of the
Internal Revenue Code, Treasury regulations, judicial opinions, published
positions of the IRS, and all other applicable authorities, all of which are
subject to change, possibly with retroactive effect.

  We urge prospective non-United States investors to consult their tax advisors
regarding the United States federal, state, local and non-United States income
and other tax considerations of acquiring, holding and disposing of shares of
our common stock.

Dividends

  As described above, we do not expect to pay you dividends. If we later decide
to pay dividends, any dividends we pay to you generally would be subject to
United States withholding tax at a rate of 30%, or a lower rate prescribed by
an applicable income tax treaty, of the gross amount of the dividends unless
the dividends were effectively connected with your conduct of a trade or
business within the United States, or if selected tax treaties apply, were
attributable to a United States permanent establishment maintained by you, and
you file the appropriate documentation with us. Dividends effectively connected
with a United States trade or business generally would be subject to United
States federal income tax on a net income basis, in the same manner as
generally applied to United States persons. If you are a corporation,
effectively connected income could also be subject to the branch profits tax at
a rate of 30%, or a lower rate as may be specified by an applicable income tax
treaty, on the repatriation from the United States of your "effectively
connected earnings and profits," subject to adjustments. If we later decide to
pay dividends, you should consult any applicable income tax treaties that may
provide for a lower rate of tax or other rules different from those described
above. You could be required to satisfy certification requirements to claim
treaty benefits or otherwise claim a reduction of, or exemption from,
withholding under these rules.

Sale or Other Dispositions of the Common Stock

  You generally will not be subject to United States federal income tax on any
gain realized upon the sale or other disposition of your shares of common stock
unless:

  .  the gain is effectively connected with the conduct of a trade or
     business within the United States, or, if some tax treaties apply, is
     attributable to a United States permanent establishment you maintain

  .  you are an individual, you hold shares of common stock as a capital
     asset, you are present in the United States for 183 days or more in the
     taxable year of disposition and you meet other requirements

                                       61
<PAGE>

  .  you are subject to tax pursuant to the provisions of the Internal
     Revenue Code regarding the taxation of some U.S. expatriates or

  .  we are or have been a "United States real property holding corporation"
     for United States federal income tax purposes, which we do not believe
     that we are or will become, and you hold or have held, directly or
     indirectly, at any time within the shorter of the five-year period
     preceding disposition or your holding period for the shares of the
     common stock, more than 5% of the common stock

  Gain that is effectively connected with your conduct of a trade or business
within the United States generally will be subject to United States federal
income tax on a net income basis, in the same manner as generally applied to
United States persons, and if you are a corporation, the branch profits tax may
also apply in some circumstances, but you will not be subject to withholding.
If you are described in the second bullet point above, you generally will be
subject to tax at a rate of 30% on the gain realized, although the gain may be
offset by some United States capital losses. You should consult any applicable
income tax treaties that may provide for a lower rate of tax or other rules
different from those described above.

Information Reporting and Backup Withholding

  We do not currently anticipate paying dividends to you, but if we decide to
pay dividends in the future, we would be required to report annually to the IRS
and to you the amount of dividends we pay you and any tax we withhold. These
reporting requirements would apply regardless of whether withholding is reduced
by an applicable income tax treaty. Backup withholding, currently at a rate of
31%, could also apply under special circumstances.

  Under current Treasury regulations, United States information reporting
requirements and backup withholding tax at a rate of 31% will generally apply
to payments to you of the proceeds of a sale of the common stock by a United
States office of a broker unless you certify, under penalties of perjury, that
you are not a U.S. holder or otherwise establish an exemption. Information
reporting, but not backup withholding, generally will also apply to payments of
the proceeds of sales of the common stock by foreign offices of United States
brokers, or foreign brokers with some types of relationships with the United
States, unless the broker has documentary evidence in its records that you are
not a U.S. holder and some other conditions are met, or you otherwise establish
an exemption.

  The IRS has issued Treasury regulations generally effective for payments made
after December 31, 2000 that will affect the procedures to be followed by you
in establishing that you are not a U.S. holder for purposes of the backup
withholding and information reporting requirements. Among other things, if you
are not currently required to furnish certification of foreign status, you may
be required to furnish certification of foreign status in the future. You
should consult your tax advisor concerning the effect of this regulation on an
investment in the common stock.

  Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules from a payment to you can be refunded or credited
against your United States federal income tax liability, if any, if the
required information is furnished to the IRS.

  Pursuant to applicable tax treaties or other agreements, any information
reported to us also may be made available to the tax authorities in the country
in which you reside or are established.

Estate Tax

  Common stock owned or treated as owned by an individual who is not a citizen
or resident, as defined for United States federal estate tax purposes, of the
United States at the time of his or her death, or specified lifetime transfers
made by the individual, will be includible in the individual's gross estate for
United States federal estate tax purposes, unless an applicable estate tax
treaty provides otherwise, and therefore may be subject to United States
federal estate tax.

  The underwriting agreement provides that the obligations of the several
underwriters to purchase and accept delivery of the shares of common stock
included in this offering are subject to approval of legal matters by their
counsel and to customary conditions, including the effectiveness of the
registration statement, the continuing correctness of our representations, the
receipt of a "comfort letter" from our accountants, the listing of the common
stock for quotation on the Nasdaq National Market and no occurrence of an event
that would have a material adverse effect on us. The underwriters are obligated
to purchase and accept delivery of all the shares of common stock, other than
those covered by the over-allotment option described below, if they purchase
any of the shares of common stock.

  The underwriters propose to offer initially some of the shares of common
stock directly to the public at the public offering price on the cover page of
this prospectus and some of the shares of common stock to dealers, including
the underwriters, at the initial public offering price less a concession not in
excess of $.  per share. The underwriters may allow, and these dealers may re-
allow, a concession not in excess of $.  per share to other dealers. After the
initial offering of the common stock to the public, the representatives of the
underwriters may change the public offering price and these concessions. The
underwriters do not intend to confirm sales to any accounts over which they
exercise discretionary authority.

  The following table shows the underwriting fees to be paid to the
underwriters by us in this offering. These amounts are shown assuming both no
exercise and full exercise of the underwriters' option to purchase additional
shares of common stock.

  VIA has granted to the U.S. underwriters an option, exercisable within 30
days after the date of the underwriting agreement, to purchase up to
additional shares of common stock at the initial public offering price less
underwriting fees. The U.S. underwriters may exercise this option solely to
cover over-allotments, if any, made in connection with the offering. To the
extent that the U.S. underwriters exercise this option, each U.S. underwriter
will become obligated, subject to conditions, to purchase a number of
additional shares approximately proportionate to that U.S. underwriter's
initial purchase commitment.

  VIA has agreed to indemnify the underwriters against specified liabilities,
including liabilities under the Securities Act, or to contribute to payments
that the underwriters may be required to make in respect of any of those
liabilities.

  VIA, our executive officers, directors and some of our stockholders have
agreed, for a period of 180 days from the date of this prospectus and subject
to some exceptions, they will not, without the prior written consent of
Donaldson, Lufkin & Jenrette Securities Corporation, do either of the
following:

  . offer, pledge, sell, contract to sell, sell any option or contract to
    purchase, purchase any option or contract to sell, grant any option,
    right or warrant to purchase or otherwise transfer or dispose of,
    directly or indirectly, any shares of common stock or any securities
    convertible into or exercisable or exchangeable for common stock; or

  . enter into any swap or other arrangement that transfers all or a portion
    of the economic consequences associated with the ownership of any common
    stock.

  Either of the foregoing transfer restrictions will apply regardless of
whether a covered transaction is to be settled by the delivery of common stock
or such other securities, in cash or otherwise. In addition, during this 180
day period and subject to specified exceptions, VIA has agreed not to file any
registration statement with respect to, and each of our executive officers,
directors and some of our stockholders has agreed not to make any demand for,
or exercise any right with respect to, the registration of any shares of common
stock or any securities convertible into or exercisable for common stock
without the prior written consent of Donaldson, Lufkin & Jenrette Securities
Corporation.

  At our request, the underwriters have reserved for sale up to      shares of
common stock offered by this prospectus for sale at the initial public offering
price to our employees, officers and directors and other persons designated by
us. The number of shares of common stock available for sale to the general
public will be reduced to the extent these individuals purchase or confirm for
purchase, orally or in writing, these reserved shares. Any reserved shares not
purchased or confirmed for purchase will be offered by the underwriters to the
general public on the same basis as the other shares offered by this
prospectus.

  We intend to apply to have our common stock approved for quotation on the
Nasdaq National Market under the symbol "VNWI."

  Under an intersyndicate agreement between the U.S. underwriters and
international managers, each U.S. underwriter has represented and agreed that,
with some exceptions:

  . it is not purchasing any shares of common stock included in this offering
    for the account of anyone other than a United States or Canadian person;
    and

  . it has not offered or sold, and will not offer or sell, directly or
    indirectly, any shares of common stock included in this offering or
    distribute any prospectus relating to the shares of common stock outside
    the United States or Canada or to anyone other than a United States or
    Canadian person.

  With respect to any underwriter that is both a U.S. underwriter and an
international manager, these representations and agreements made by it in its
capacity as a U.S. underwriter apply only to it in its capacity as a U.S.
underwriter and made by it in its capacity as an international manager apply

branch of a person other than a United States or Canadian person.

  Under the intersyndicate agreement, sales may be made between the syndicates
of U.S. underwriters and international managers of a number of the shares of
common stock included in this offering as may be mutually agreed. Unless
otherwise determined by the representatives of the U.S. underwriters and
international managers, the per share price of any shares of common stock so
sold shall be the initial public offering price set forth on the cover page
hereof, in United States dollars, less an amount not greater than the per share
amount of the concession to dealers described above.

agreed that:

    applicable securities laws; and

  . without limiting the generality of the foregoing, any offer or sale of
    shares of common stock in Canada will be made only pursuant to an
    exemption from the requirement to file a prospectus in the province or
    territory of Canada in which the offer or sale is made.

  Each U.S. underwriter has further agreed to send to any dealer who purchases
from it any shares of common stock included in this offering a notice stating

represents and agrees that:

    indirectly, any of those shares of common stock in any province or
    territory of Canada or to, or for the benefit of, any resident of any
    province or territory of Canada in contravention of applicable securities
    laws;

  . any offer or sale of those shares of common stock in Canada will be made
    only pursuant to an exemption from the requirement to file a prospectus
    in the province or territory of Canada in which the offer or sale is
    made; and

    common stock a notice containing substantially the same statement as is
    contained in this sentence.

  Under the intersyndicate agreement, each international manager has
represented and agreed that:

  . it has not offered or sold and, prior to the date six months after the
    closing date for the sale of shares of common stock to the international
    managers under the Underwriting Agreement, will not offer or sell, any
    shares of common stock included in this offering to persons in the United
    Kingdom except to

                                       65
<PAGE>

   persons whose ordinary activities involve them in acquiring, holding,
   managing or disposing of investments, as principal or agent, for the
   purposes of their businesses or otherwise in circumstances which have not
   resulted and will not result in an offer to the public in the United
   Kingdom within the meaning of the Public Offers of Securities Regulations
   1995;

  . it has complied and will comply with all applicable provisions of the
    Financial Services Act 1986 with respect to anything done by it in
    relation to the shares of common stock included in this offering in, from
    or otherwise involving the United Kingdom; and

  . it has only issued or passed on and will only issue or pass on in the
    United Kingdom any document received by it in connection with this
    offering to a person who is of a kind described in Article 11(3) of the
    Financial Services Act 1986 (Investment Advertisements) (Exemptions)
    Order 1996 or is a person to whom the document may otherwise lawfully be
    issued or passed on.

  Under the intersyndicate agreement, each international manager has
represented and agreed that it has not offered or sold and will not offer or
sell, directly or indirectly, any shares of common stock acquired in connection
with the distribution contemplated in this prospectus in Japan or to or for the
account of any resident thereof, except for offers or sales to Japanese
international managers or dealers and except pursuant to an exemption from the
registration requirements of the Securities and Exchange Law of Japan and
otherwise in compliance with applicable provisions of Japanese law. Each
international manager has agreed to send to any dealer who purchases from it
any shares of common stock included in this offering a notice stating in
substance that by purchasing those shares of common stock that dealer
represents and agrees that:

  . it has not offered or sold and will not offer or sell, directly or
    indirectly, any of those shares of common stock in Japan or to or for the
    account of any resident thereof, except for offers or sales to Japanese
    international managers or dealers and except pursuant to an exemption
    from the registration requirements of the Securities and Exchange Law of
    Japan and otherwise in compliance with applicable provisions of Japanese
    law; and

  . it will send to any other dealer to whom it sells any of those shares of
    common stock a notice containing substantially the same statement as is
    contained in this sentence.

  Other than in the United States, no action has been taken by VIA or the
underwriters that would permit a public offering of the shares of common stock
offered by this prospectus in any jurisdiction where action for that purpose is
required. The shares of common stock offered through this prospectus may not be
offered or sold, directly or indirectly, nor may this prospectus or any other
offering material or advertisements associated with the offer and sale of any
the shares of common stock offered through this prospectus be distributed or
published in any jurisdiction, except under circumstances that will result in
compliance with the applicable rules and regulations of that jurisdiction. You
should inform yourself and observe any restrictions relating to the offering of
the common stock and the distribution of this prospectus. This prospectus does
not constitute an offer to sell or a solicitation of an offer to buy any shares
of common stock included in this offering in any jurisdiction where that would
not be permitted or legal.

Stabilization

  In connection with the offering, the underwriters may engage in transactions
that stabilize, maintain or otherwise affect the price of the common stock.
Specifically, the underwriters may over-allot the offering, creating a
syndicate short position. The underwriters may bid for and purchase shares of
common stock in the open market to cover a syndicate short position or to
stabilize the price of the common stock. In addition, the underwriting
syndicate may reclaim selling concessions from syndicate members and selected
dealers if Donaldson, Lufkin & Jenrette Securities Corporation repurchases
previously distributed common stock in syndicate covering transactions, in
stabilization transactions or otherwise if Donaldson, Lufkin & Jenrette
Securities Corporation receives a report that indicates that the clients of
such syndicate members have "flipped" the common stock. These activities may
stabilize or maintain the market price of the common stock

                                       66
<PAGE>

above independent market levels. The underwriters are not required to engage in
these activities, and may end any of these activities at any time.

Pricing of the Offering

  Prior to the offering, there has been no established trading market for our
common stock. The initial public offering price of our common stock will be
determined by negotiation among VIA and the representatives of the
underwriters. The factors to be considered in determining the initial public
offering price include:

  .the history of and the prospects for the industry in which VIA competes
  .VIA's past and present operations
  .VIA's historical results of operations
  .VIA's prospects for future earnings
  .the recent market prices of securities of generally comparable companies
     and

     offering

                              VIA NET.WORKS, INC.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

  During the period beginning September 24, 1998 through November 23, 1999,
VIA NET.WORKS, Inc. (the "Company") completed numerous business combinations,
whereby the Company acquired either 100% or a majority of the voting stock of
companies operating as Internet services providers in Europe and Latin America
(collectively, the "Completed Acquisitions"). All of the Completed Acquisitions
have been or will be accounted for using the purchase method of accounting. The
Completed Acquisitions are described in Note 1--Basis of Presentation to the
accompanying unaudited pro forma condensed combined financial statements.

  The unaudited pro forma condensed combined balance sheet as of September 30,
1999 gives effect to the acquisition of InfoAcces S.A. de C.V. ("InfoAcces")
which occurred subsequent to September 30, 1999 and the conversion of the
outstanding mandatorily redeemable convertible preferred stock into common
stock. The unaudited pro forma condensed combined statements of operations for
the year ended December 31, 1998 and for the nine-month period ended
September 30, 1999 give effect to the acquisition of 15 companies between
January 1, 1998 and September 30, 1999 and the acquisition of InfoAcces, as
though these acquisitions had occurred on January 1, 1998.

  The unaudited pro forma condensed combined statements of operations are not
necessarily indicative of the results of operations that would actually have
occurred if the transactions had been consummated as of January 1, 1998 and is
not intended to indicate the expected results for any future period. These
statements should be read in conjunction with the historical consolidated
financial statements and related notes thereto of the Company, and the
financial statements of certain of the completed acquisitions, included herein.

  The allocation of the purchase price to the acquired tangible and intangible
assets of certain of Completed Acquisitions has not been finalized pending an
analysis of the nature of the intangible assets acquired. The actual purchase
accounting adjustments may be revised, and the Company may allocate a portion
of the purchase price to intangible assets other than goodwill. Such intangible
assets may have an estimated useful life that differs from the five-year life
used for the amortization of goodwill. Any adjustment could have a material
impact on the pro forma statements of operations.

(3) PRO FORMA ADJUSTMENTS

 Pro Forma Condensed Combined Balance Sheet

  (a) To reflect cash of $35.0 million paid for the acquisition of InfoAcces,
including estimated acquisition costs of $966,000. Under the terms of the
purchase agreement for InfoAcces, the sellers may be entitled to additional
consideration based on the results of InfoAcces following the acquisition in an
amount not to exceed $30.0 million. Such additional consideration has not been
reflected in the accompanying pro forma balance sheet but will be reflected as
additional goodwill when paid. Under the terms of the acquisition, the Company
was required to place $15.0 million in escrow (declining $0.50 for every $1.00
of contingent consideration earned and paid out) pending determination of the
contingent consideration.

  (b) To reflect the allocation of the purchase price in excess of the
historical book value of the acquired assets of InfoAcces. Based on preliminary
estimates, in the opinion of management, the historical balances of all other
assets acquired and liabilities have been determined to approximate fair value.
Of the total purchase price $1.0 million has been allocated to a two-year non-
compete agreement and $31.2 million has been allocated to goodwill.

  (c) To reflect the conversion of outstanding manditorily redeemable
convertible preferred stock of the Company into common stock to occur in
conjunction with the offering, including common stock of $40,000 and additional
paid in capital of $180.9 million.

  (d) To eliminate the historical equity of InfoAcces including common stock of
$5.2 million, additional paid in capital of $389,000 and accumulated deficit of
$1.8 million.

 Pro Forma Condensed Combined Statements of Operations

  (e) To reflect amortization expense of goodwill based on an estimated life of
five years and non-compete agreement based on an estimated life of two years.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of VIA NET.WORKS, Inc.

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, stockholders' deficit and cash flows
present fairly, in all material respects, the financial position of VIA
NET.WORKS, Inc. and its subsidiaries at December 31, 1997 and 1998, and the
results of their operations and their cash flows for the period from June 13,
1997 (inception) through December 31, 1997 and for the year ended December 31,
1998, in conformity with generally accepted accounting principles. These
consolidated financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these consolidated
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

        (In thousands of U.S. Dollars, except share and per share data)

1. Organization and Summary of Significant Accounting Policies

 Organization and Nature of Operations

  VIA NET.WORKS, Inc. (the "Company" or "VIA") was founded on June 13, 1997 for
the purpose of acquiring existing Internet services providers around the world.
The focus of the Company is to be a leading, full-service global provider of
Internet connectivity and services, including web hosting, e-commerce, Internet
security and other services, primarily to the small and mid-sized business
market. In 1997, the Company was considered a development stage enterprise, as
it had no significant revenue from principal operations through December 31,
1997. In 1998, the Company acquired or invested in five companies, four of
which have been consolidated in the accompanying consolidated financial
statements. The Company is no longer considered a development stage enterprise.
In 1999, the Company amended its Certificate of Incorporation to change the
Company's name from V-I-A Internet, Inc. to VIA NET.WORKS, Inc.

 Risks and Uncertainties

  The Company has a limited operating history and its operations are subject to
certain risks and uncertainties, including those associated with: the ability
to meet obligations; continuing losses, negative cash flow and fluctuations in
operating results; funding expansion; acquisitions and strategic alliances,
including their integration; managing rapid growth and expansion; international
business activities; suppliers; financing arrangement terms that may restrict
operations; possible Year 2000 issues; regulatory issues; competition in the
Internet services industry; technology trends and evolving industry standards;
and delivering reliable service.

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires the Company to make estimates, judgments and
assumptions that affect the reported amounts of assets, liabilities, revenue
and expenses, together with amounts disclosed in the related notes to the
consolidated financial statements. Actual results could differ from the
recorded estimates.

 Principles of Consolidation

  The accompanying consolidated financial statements include the accounts of
the Company and its majority-owned and controlled subsidiaries, as described in
Note 3. All significant intercompany accounts and transactions have been
eliminated in consolidation. Investments in 20% to 50% owned affiliates over
which the Company has the ability to exercise significant influence are
accounted for under the equity method. Under the equity method of accounting,
an investee's results of operations are not reflected within the Company's
consolidated accounts; however, the Company's share of the earnings or losses
of the investee is reflected in the caption "loss in unconsolidated affiliate"
in the consolidated statements of operations. In applying the equity method to
investments in voting preferred stock, the Company recognizes losses based on
its share of ownership interest of the preferred stock once common equity of
the investee has been fully depleted.

 Revenue Recognition

  Revenue from Internet connectivity and value-added Internet services are
recognized as the services are provided. The Company records deferred revenue
for amounts billed and/or collected in advance. Revenue from consulting,
installation and maintenance services are recognized as the services are
provided. Revenue from hardware and third-party software sales is recognized
upon delivery or installation of the respective products, depending on the
terms of the arrangement.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

        (In thousands of U.S. Dollars, except share and per share data)


 Cash and Cash Equivalents

  The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.

 Concentration of Credit Risk

  Financial instruments that potentially subject the Company to a concentration
of credit risk consist of cash and cash equivalents, and accounts receivable.
The Company's cash and investment policies limit investments to short-term,
investment grade instruments. Concentration of credit risk with respect to
accounts receivable are limited due to the large number and geographic
dispersion of customers comprising the Company's customer base.

 Property and Equipment

  Property and equipment are recorded at cost less accumulated depreciation,
which is provided on the straight-line method over the estimated useful lives
of the assets, generally three to five years. Cost includes major expenditures
for improvements and replacements, which extend useful lives or increase
capacity of the assets. Expenditures for maintenance and repairs are expensed
as incurred.

 Goodwill

  The Company has recorded goodwill related to its acquisitions. Goodwill is
amortized over five years.

 Long-Lived Assets

  The Company periodically evaluates the carrying value of property and
equipment to be held and used when events and circumstances warrant such a
review. The carrying value of property and equipment is considered impaired
when the anticipated undiscounted cash flows from the asset is separately
identifiable and is less than its carrying value. In that event, a loss is
recognized based on the amount by which the carrying value exceeds the fair
value of the asset. Fair value is determined primarily using the anticipated
cash flows discounted at a rate commensurate with the risk involved. Losses on
assets to be disposed of are determined in a similar manner, except that fair
values are reduced for the cost to dispose.

 Advertising Costs

  Costs related to advertising and promotion of service are charged to
operating expense as incurred. Advertising expense was $5 and $975 for the
period from June 13, 1997 (inception) to December 31, 1997 and the year ended
December 31, 1998, respectively.

 Income Taxes

  The Company accounts for income taxes under the asset and liability method,
which requires the recognition of deferred tax assets and liabilities for the
expected future tax consequences of temporary differences between the carrying
amounts and tax bases of assets and liabilities. The Company provides a
valuation allowance on net deferred tax assets when it is more likely than not
that such assets will not be realized. In conjunction with business
acquisitions, the Company records acquired deferred tax assets and liabilities.
Future reversals of the valuation allowance on acquired deferred tax assets
will first be applied against goodwill and other intangibles before recognition
of a benefit in the consolidated statements of operations.

 Stock-Based Compensation

  SFAS No. 123, Accounting for Stock-Based Compensation, encourages, but does
not require companies to record compensation cost for stock-based employee
compensation plans at fair value. The Company has chosen to account for stock-
based compensation using the intrinsic value method prescribed in Accounting
Principles Board Opinion ("APB") No. 25, Accounting for Stock Issued to
Employees, and related Interpretations. Accordingly, compensation cost for
stock options is measured as the excess, if any, of the estimated fair value

                              VIA NET.WORKS, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

        (In thousands of U.S. Dollars, except share and per share data)

of the Company's stock at the date of the grant over the amount an employee
must pay to acquire the stock. The Company has adopted the "disclosure only"
alternative described in SFAS No. 123 which requires pro forma disclosures of
net income and earnings per share as if the fair value method of accounting has
been applied.

 Foreign Currency

  The functional currency for the Company's international subsidiaries is the
applicable local currency. Accordingly, net assets are translated at year-end
exchange rates while revenue and expenses are translated at the average
exchange rates. Adjustments resulting from these translations are accumulated
and reported as a component of accumulated other comprehensive loss in
stockholders' deficit. At December 31, 1997 and 1998, the cumulative foreign
currency translation adjustment was $0 and $434, respectively. Transaction
gains or losses, including gains or losses on foreign currency denominated
intercompany balances, are recorded in the consolidated statements of
operations.

 Fair Value of Financial Instruments

  Carrying amounts of certain of the Company's financial instruments, including
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses and other liabilities approximate fair value due to their short
maturities. Based upon borrowing rates currently available to the Company for
loans with similar terms, the carrying value of debt and capital lease
obligations approximate their fair value.

 Loss Per Share

  Basic loss per share is computed using the weighted-average number of shares
of common stock outstanding during the year. Diluted loss per share is computed
using the weighted-average number of shares of common stock, adjusted for the
dilutive effect of common stock, equivalent shares of common stock options and
warrants and contingently issuable shares of common stock. Common stock
equivalent shares are calculated using the treasury stock method. All stock
options, convertible preferred stock and warrants outstanding have been
excluded from the computation of diluted loss per share, as their effect would
be antidilutive. Accordingly, there is no reconciliation between basic and
diluted loss per share for each of the periods presented.

 Comprehensive Income

  The Company adopted SFAS No. 130, Reporting Comprehensive Income, in 1998.
SFAS No. 130 establishes standards for reporting and displaying comprehensive
income and its components. Comprehensive loss consists of net loss and foreign
currency translation adjustments as presented in the consolidated statement of
stockholders' deficit. The adoption of SFAS No. 130 had no impact on total
stockholders' deficit or net loss.

 Segment Reporting

  The Company adopted SFAS No. 131, Disclosures about Segments of an Enterprise
and Related Information, during 1998. SFAS No. 131 replaces the "industry
segment" approach with the "management" approach to reporting financial
information about an enterprise's segments. The management approach designates
the internal organization that is used by management for allocating resources
and assessing performance as the source of the Company's reportable segments.
SFAS No. 131 also requires disclosures about products and services, geographic
areas, and major customers. The adoption of SFAS No. 131 did not effect the
Company's results of operations or financial position.

 Recent Pronouncements

  In 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-1, Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use, and SOP 98-5, Reporting on the
Costs of Start-Up Activities, both of which are required to be adopted for
fiscal years beginning after December 15, 1998. SOP 98-1 provides guidance on
accounting for the costs of computer software developed or obtained for
internal use, determining whether computer software is for internal use, and
when costs incurred for internal-use computer software are and are not
capitalized. SOP 98-5 requires costs of start-up activities and organization
costs to be expensed as incurred. The adoption of SOP 98-1 and SOP 98-5 did not
have a material effect on the Company's consolidated financial statements.

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 establishes a new model for accounting for derivatives and
hedging activities and supersedes and amends a number of existing standards.
SFAS No. 133 is effective for fiscal years beginning after June 15, 1999, but
earlier application is permitted as of the beginning of any fiscal quarter
subsequent to June 15, 1998. Upon initial application, all derivatives are
required to be recognized in the statement of financial position as either
assets or liabilities and measured at fair value. In addition, all hedging
relationships must be reassessed and documented pursuant to the provisions of
SFAS No. 133. Subsequent to the issuance of SFAS No. 133, the Financial
Accounting Standards Board issued SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133", which defers the effective date of SFAS No. 133 to periods
beginning after June 15, 2000. The Company has not committed or expects to
commit to any derivative instrument transactions, and thus does not anticipate
that this pronouncement will have a significant effect on its results.

 Interim Financial Information (Unaudited)

  Interim financial information for the nine months ended September 30, 1998
and 1999 included herein is unaudited. However, the Company believes the
interim financial information includes all adjustments, consisting of only
normal recurring adjustments, necessary for a fair presentation of the results
of interim periods. The results of operations for the nine months ended
September 30, 1999 are not necessarily indicative of the results to be expected
for the year ending December 31, 1999.

 Pro Forma Stockholder's Equity (Unaudited)

  The unaudited pro forma stockholders' equity presents the effect of the
automatic conversion of all of the outstanding mandatorily redeemable
convertible preferred stock into shares of common stock on a one-for-one basis
upon the closing of an Initial Public Offering (IPO) (see Note 8). The
conversion of the mandatorily redeemable convertible preferred stock has been
reflected in the accompanying unaudited pro forma stockholders' equity as if it
had occurred on September 30, 1999.

2. Investment in Affiliate

  In June 1998, the Company acquired a 36% interest in i-way Limited (i-way) an
Internet services provider located in the United Kingdom. The Company purchased
voting preferred stock for $2,781. The Company had the option to purchase the
remaining 64% equity interest in i-way pursuant to certain conditions as set

        (In thousands of U.S. Dollars, except share and per share data)


  Subsequent to the date of the preferred stock investment and for the year
ended December 31, 1998, and the nine months ended September 30, 1999, i-way
incurred losses of $1,137 and $253 (unaudited), respectively. As discussed in
Note 1, because the common equity of i-way has been fully depleted, the Company
has recognized the full amount of the investee's loss arising subsequent to the
date of the investment. Additionally, the Company is amortizing the accumulated
deficit of i-way, at the date of acquisition, over a five-year period. The
amortization is included in the Company's consolidated statements of operations
in the amount of $62 for the year ended December 31, 1998.

  In June 1999, the Company negotiated the purchase of the remaining 64% equity
interest in i-way for total consideration of $13,097, comprised of $10,479 in
cash and 317,421 of the Company's common stock, valued at $8.25 per share. The
transaction was consummated on August 5, 1999.

  Each of the acquisitions was accounted for using the purchase method of
accounting and, accordingly, the net assets and results of operations of the
acquired companies have been included in the Company's consolidated financial
statements since the acquisition dates. The purchase price of the acquisitions
was allocated to assets acquired, including intangible assets, and liabilities
assumed, based on their respective fair values at the acquisition dates. The
companies acquired are Internet services providers, offering services including
Internet connectivity, web hosting, e-commerce, Internet security and other
services, primarily small and mid-sized businesses. See Note 7 regarding
disclosure of notes payable issued in connection with these acquisitions.

  The Company has the right to purchase the remaining 49% interest in VIA Net
Works Argentina, GTN and Dialdata during certain contractual time periods
ending March 24, 2002, October 9, 2002, and May 29, 2002, respectively. In
connection with the Dialdata acquisition, assuming the Company does not
exercise its option, the existing stockholders have the right to purchase all
the shares held by VIA over a period of 90 days beginning on May 30, 2002.
Pursuant to these purchase agreements, the Company entered into employment
agreements with varying terms, with certain officers of the acquired companies.

  All companies were acquired directly by the Company, except for
Informationstechnik, Netzwerke und Systeme Vertriebs GmbH and Ecce Terram GmbH
("Ecce Terram"), which were acquired by GTN, a majority-owned subsidiary.

  Netlink was acquired for $9,068 in cash and 394,124 shares of the Company's
common stock, valued at $8.25 per share. In conjunction with the acquisitions
of Esoterica-Novas Technologias de Informacao S.A.("Esoterica"), Worldwide Web
Services ("WWS"), and Ecce Terram, the Company entered into promissory notes
with the selling shareholders for a portion of the the purchase price, as

  The promissory notes are denominated and payable in the applicable local
currency. All notes bear interest at 5% per annum. Upon maturity, certain of
the promissory notes are payable at an amount equal to the greater of the
principal and accrued interest or a valuation formula based on the revenues and
earnings before interest,

taxes, depreciation and amortization of the acquired business, as calculated at
maturity. The Esoterica and WWS notes require the continued employment of
certain of the selling shareholders to entitle the holders to receive the
amount based on the valuation formula.

  The Esoterica and WWS promissory notes are payable in common stock or cash at
the option of the holder. If the holder elects payment in common stock, the
stock will be valued at fair value. Upon an IPO of the Company, payment of the
promissory notes can be accelerated at the option of the Company or the holder
in which case the common stock will be valued at the IPO price. Payment date
for the notes may be extended for 6 months at the option of the holder. The
Disbumad promissory notes are payable 50% in cash and 50% in common stock
valued at fair value.

  The principal amount of these promissory notes has been included as a
component of the initial purchase price. Upon payment of the Ecce Terram
promissory note, any excess of the amount determined under the valuation
formula over the principal amount will be recorded as additional purchase
consideration at that time. Because the valuation formula of the WWS and
Esoterica promissory notes is only applicable in the event that certain selling
shareholders remain with as employees of the Company, any excess of the
valuation formula over the principal amount will be recognized as a additional
compensation expense.

  In September 1999, the Company negotiated the early retirement of the WWS
promissory note for $4,124, (inclusive of accrued interest) paid in 332,926
shares of common stock valued at $8.25 per share and $1,377 in cash. The
Company recognized approximately $400,000 (unaudited) in compensation expense
in the nine months ended September 30, 1999.

  In July 1999, the Company purchased the remaining 49% equity interest in VIA
Net Works Argentina S.A. for $2,595, comprised of $1,357 in cash and 150,000 of
the Company's common stock, valued at $8.25 per share.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

        (In thousands of U.S. Dollars, except share and per share data)


  In May 1998, the Company issued 15,795,335 shares of mandatorily redeemable
convertible Series B-1 preferred stock ("Series B-1") and 1,400,000 shares of
mandatorily redeemable convertible Series B-2 non-voting preferred stock
("Series B-2"), collectively ("Series B") at $3.00 per share.

  In April 1999, the Company issued 15,939,657 shares of Series C-1 mandatorily
redeemable convertible preferred stock ("Series C-1") and 5,370,001 shares of
mandatorily redeemable convertible Series C-2 non-voting preferred stock
("Series C-2"), collectively ("Series C") at $6.00 per share.

  The shares of Series A, Series B-1 and Series C-1 are convertible, at the
option of the holder, into equivalent shares of common stock. The shares of
Series B-2 and Series C-2 are convertible, at the option of the holder, into
equivalent shares of non-voting common stock. Shares of Series B-2 and C-2 are
convertible into shares of Series B-1 and Series C-1, respectively on a share-
for-share basis at the option of the holder. The conversion ratios are subject
to adjustment for antidilution provisions.

  In the event of liquidation, dissolution or winding up of the Company, the
Series C holders will be entitled to a liquidation preference over payments to
Series B holders, Series A holders and common stockholders equal to the
investment price plus all declared but unpaid dividends. The holders of Series
B will be entitled to be paid out of the assets prior and in preference to any
payments to Series A and common stockholders. The holders of Series A will be
entitled to be paid out of the assets prior and in preference to any payments
to common stockholders. The preference payments would be in an amount per share
equal to the investment price plus all declared but unpaid dividends. The
holders of Series A and Series B-1 shares, voting as a single class, may elect
four directors to serve on the Company's Board of Directors. The holders of
Series C-1 shares, voting as a single class, may elect three directors to serve
on the Company's Board of Directors.

  Series C participates on an as-converted basis in all dividends payable to
the holders of common stock. Both the Series A and Series B shares are
noncumulative and nonparticipating. Any declared, but unpaid dividends may also
be converted at the option of the holder, into shares of common stock on the
same terms as the underlying preferred stock.

  Concurrent with the private placement of Series C, the Company amended and
restated its Articles of Incorporation (the "Amendment"). The Amendment
increased the total authorized shares of voting common stock of the Company to
57,000,000 shares, increased the total authorized shares of non-voting common
stock of the Company to 7,500,000 shares, increased the total authorized shares
of the preferred stock of the Company to 48,000,000 shares and modified the
redemption rights of the preferred stock whereby the Company must redeem for
cash all outstanding shares of Series A, Series B, and Series C on May 31,
2008.

  The Amendment also amended the automatic conversion feature of all
outstanding preferred stock in the event of an IPO. Upon the closing of an IPO
in which the IPO price per share is at least $12.00 per share, and the gross
cash proceeds to the Company are at least $50,000, each share of the Series A,
Series B-1, Series B-2, Series C-1 and Series C-2 preferred stock automatically
converts into shares of voting or non-voting common stock, based upon the then
effective conversion price, currently on a one-for-one basis.

9. Stock Compensation and Retirement Plans

 Key Employee Equity Plan

  During 1998, the Company adopted the V-I-A Internet Inc. Key Employee Equity
Plan (the "KEEP Plan"), an incentive plan. The KEEP Plan provides for the
granting of stock purchase rights to key employees of the Company. Rights are
granted with an exercise price as determined by the Company's Board of
Directors.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

        (In thousands of U.S. Dollars, except share and per share data)

The stock purchase rights vest immediately and expire on dates specified by the
Board of Directors. As of December 31, 1998 and September 30, 1999, the Company
has reserved 400,000 and 800,000 (unaudited), respectively, common shares for
issuance under the KEEP Plan.

 Stock Option Plan

  During 1998, the Company adopted the V-I-A Internet Inc. Stock Option and
Restricted Stock Plan (the "Option Plan"). The Option Plan allows the Company
to issue employees either incentive or non-qualified options, which options
vest over such periods as may be determined by the Board of Directors. The
vesting period is established in each grant award agreement agreed by the Board
of Directors, generally two to four years. The options expire ten years after
grant date. The Option Plan allows for grants, which would allow the grantees
to exercise their options prior to vesting in exchange for restricted common
stock or restricted stock units, however, no such grants have been made.
Options are granted with an exercise price equal to the estimated fair value of
the common stock at the date of grant as determined by the Company's Board of
Directors. As of December 31, 1998 and September 30, 1999 the Company has
reserved 1,600,000 and 4,200,000 (unaudited), respectively, common shares for
issuance under the Option Plan.

 Warrants for Common Stock

  In April 1998, the Company issued warrants to purchase 100,000 shares of
common stock at an exercise price of $2.40, to a non-employee member of the
Board of Directors. These warrants vest immediately and expire five years from
the grant date. As of December 31, 1998 no warrants have been exercised.

 Fair Value of Stock Options and Warrants

  For disclosure purposes under SFAS No. 123, the fair value of each stock
option and warrant granted is estimated on the date of grant using the Black
Scholes option-pricing model with the following weighted-average assumptions:

<TABLE>
<CAPTION>
                                                  KEEP Plan Option Plan Warrants

   Dividend yield................................      0%          0%       0%
</TABLE>

  Utilizing these assumptions, the weighted-average fair value of the stock
options and warrants granted in 1998 was $0.02, and $0.36, and $0.53 for the
KEEP Plan, Option Plan, and warrants, respectively.

  Under the above model, the total value of stock options and warrants granted
was approximately $440 in 1998, which would be amortized on a pro forma basis
over the option-vesting period. Had the Company determined compensation cost
for these plans in accordance with SFAS No. 123, the Company's pro forma
results for the year ended December 31, 1998 would have been as follows:

</TABLE>

  All stock purchase rights and options granted during 1998 were granted with
exercise prices equal to the fair market value as determined by the Board of
Directors. During the nine months ended September 30, 1999, the Company
determined that the fair value of the underlying common stock exceeded the
exercise price of certain stock purchase right and stock option grants by
$1,816 (unaudited.) Such amount will be amortized over the vesting period. The
Company recognized an expense of $483 (unaudited) in the nine months ended
September 30, 1999.

  In October 1999, the Company granted 1,890,000 (unaudited) stock options, at
an exercise price of $9.00 (unaudited) per share. None of these options have
been exercised.

  The gross deferred tax assets have been reduced by a valuation allowance
because it is currently more likely than not that such benefits will not be
realized. The change in the valuation allowance was an increase of $1,042 in
1998, which is primarily related to additional losses from operations and
start-up costs.

        (In thousands of U.S. Dollars, except share and per share data)


  At December 31, 1997 and 1998, the Company has a U.S. net operating loss
carryforward of approximately $321 and $1,419, respectively, which may be used
to offset future taxable income. This carryforward expires in 2018 and 2012,
respectively. The Internal Revenue Code places certain limitations on the
annual amount of net operating loss carryforwards which can be utilized if
certain changes in the Company's ownership occur.

  At December 31, 1997, the Company did not have any net operating losses
generated from foreign subsidiaries. At December 31, 1998, the Company has net
operating losses generated from its foreign subsidiaries of approximately $406
of which $364 will begin to expire in 2003 and $42 which have an indefinite
carryforward period.

course of business. In the opinion of management, no such matter, individually
or in the aggregate, exists which is expected to have a material effect on the
results of operations, cash flows or financial position of the Company.

12. Segment Reporting

  The Company offers Internet connectivity, web hosting, e-commerce, Internet
security and related services to businesses and consumers in Europe and Latin
America. Both segments generate Internet-related revenues from leased lines,
dial-up Internet access, web hosting and design, consulting services, and
hardware and software sales.

  Each of these geographic operating segments is considered a reportable
segment, and the accounting policies of the operating segments are the same as
those described in Note 1. The Company evaluates the performance of its
segments based on revenue and earnings before interest, taxes, depreciation and
amortization

   Management and
    Communications S.A.
    (M&C).................... Switzerland October 11, 1999  $ 3,300      60%
</TABLE>

  In October 1999, the Company acquired all of the outstanding common stock of
InfoAcces, an Internet services provider located in Mexico City. The purchase
consideration consisted of a $35.0 million initial cash payment and a maximum
of $30.0 million of contingent earn-out payments based on a formula valuation
through December 2000. In connection with the contingent consideration, the
Company has placed $15.0 million in escrow.

        (In thousands of U.S. Dollars, except share and per share data)


  Additionally, in October 1999, the Company acquired 60% of the outstanding
shares of M&C an Internet services provider operating in Switzerland. The
purchase price consisted of cash of $2.1 million payable over a 12 month
period. Following twelve months from the closing of the transaction or under
certain other circumstances, including an IPO, the Company has an option to
acquire the remaining interest in M&C based on a valuation formula, payable in
shares of the Company.

  The purchase price will be allocated to the acquired tangible and intangible
assets of the acquired businesses. It is anticipated that any resultant
goodwill will be amortized over a 5-year period.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of VIA Net Works Argentina S.A.

In our opinion, the accompanying balance sheets and the related statements of
operations, stockholders' deficit, and cash flows expressed in Argentine pesos,
present fairly, in all material respects, the financial position of VIA Net
Works Argentina S.A. as of September 24, 1998 and December 31, 1997, and the
results of its operations and its cash flows for the period from January 1,
1998 to September 24, 1998 and the year ended December 31, 1997, in conformity
with accounting principles generally accepted in the United States of America.
These financial statements are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements based
on our audit. We conducted our audits of these financial statements in
accordance with generally accepted auditing standards in Argentina which are
substantially similar to generally accepted auditing standards in the United
States of America which 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, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for the opinion expressed above.

NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Business Operations

  VIA Net Works Argentina S.A. ("the Company") was formed on September 22,
1995, to operate as an Internet Services Provider (ISP) in the city of Buenos
Aires. Operations commenced in 1996. On September 24, 1998, 51% of the common
stock shares were acquired by VIA NET.WORKS, Inc. for total consideration of
AR$3,926. On July 27, 1999, VIA NET.WORKS, Inc. acquired the remaining 49% of
the Company for total consideration of AR$2,594.

 Basis of Presentation

  The Company maintains its accounting records in accordance with generally
accepted accounting principles (GAAP) in the country of Argentina. These
financial statements have been prepared in accordance with GAAP in the United
States for purposes of filing with the Securities and Exchange Commission and
do not represent the statutory financial statements of the Company. The
accompanying financial statements include the results of the Company for the
year ended December 31, 1997 and for the period from January 1, 1998 to
September 24, 1998 (the date that the Company was acquired by VIA NET.WORKS,
Inc.).

  Amounts in these financial statements are presented in Argentine pesos (AR$)
unless otherwise indicated. Since inception of the Company, the exchange rate
with the U.S. dollar has been AR$1 = US$1.

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires the Company to make estimates, judgements and
assumptions that affect the reported amounts of assets, liabilities, revenue
and expenses, together with amounts disclosed in the related notes to the
financial statements. Actual results could differ from the recorded estimates.

 Fair Value of Financial Instruments

  Carrying amounts of certain of the Company's financial instruments, including
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses and other liabilities approximate fair value due to their short
maturities. Based upon borrowing rates currently available to the Company for
loans with similar terms, the carrying value of debt and capital lease
obligations approximate their fair value.

 Cash and Cash Equivalents

  The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.

 Concentration of Credit Risk

  Financial instruments that potentially subject the Company to a concentration
of credit risk consist of cash, cash equivalents and accounts receivable. The
Company's accounts receivable are derived from revenue earned from customers
located primarily in the city of Buenos Aires. The Company performs ongoing
credit evaluations of its customers' financial condition and, generally,
requires no collateral from its customers. The Company maintains an allowance
for doubtful accounts receivable based upon the expected collectibility of
accounts receivable.

24, 1998 and receivables at December 31, 1997 and September 24, 1998 were
concentrated principally with four customers as follows (amounts represent

</TABLE>

 Equipment and Furniture

  Equipment and furniture are recorded at cost less accumulated depreciation,
which is provided on the straight-line method over the estimated useful lives
of the assets, generally three to ten years. Communication and computer
equipment is depreciated over 3 years and furniture and fixtures over 10 years.
Cost includes major expenditures for improvements and replacements which extend
the useful life or increase capacity of the asset. Expenditures for maintenance
and repairs are expensed as incurred.

  Costs for internal use software are expensed as incurred.

 Long-Lived Assets

  The Company periodically evaluates the carrying value of property and
equipment to be held and used when events and circumstances warrant such a
review. The carrying value of property and equipment is considered impaired
when the anticipated undiscounted cash flows from the asset is separately
identifiable and is less than its carrying value. In that event, a loss is
recognized based on the amount by which the carrying value exceeds the fair
value of the asset. Fair value is determined primarily using the anticipated
cash flows discounted at a rate commensurate with the risk involved. Losses on
assets to be disposed of are determined in a similar manner, except that fair
values are reduced for the cost to dispose.

  Management estimates that there is no impairment of assets.

 Advertising Expense

  Costs related to advertising and promotion of services is charged to sales
and marketing expense as incurred. Advertising expense for all periods
presented is immaterial.

 Dismissal Indemnities

  Dismissal indemnities, required in the event of involuntary termination and
payable in accordance with Argentine law, are expensed when incurred.

 Income Taxes

  The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes". SFAS No. 109 is an asset and liability approach
that requires the recognition of deferred tax assets and

                                      F-39
<PAGE>

                          VIA NET WORKS ARGENTINA S.A.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

       (All amounts in thousands of AR$ except share and per share data)

liabilities for the expected future tax consequences attributable to
differences between the carrying amounts of assets and liabilities for
financial reporting purposes and their respective tax bases, and for operating
loss and tax credit carryforwards. In estimating future tax consequences, SFAS
No. 109 generally considers all expected future events other than the enactment
of changes in tax laws or rates.

 Revenue Recognition

  Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and collected in advance.

  Revenue from consulting services is recognized as the services are provided.
Revenue from hardware and third-party software sales is recognized upon
shipment of the respective products. Through December 31, 1998, such sales have
been immaterial.

 Costs of Revenues

  Costs of access revenues consists of telecommunication expenses inherent in
the network infrastructure.

 Sources of Suppliers

  The Company relies on local telephone companies and other companies to
provide data communications. Athough management believes that alternative
telecommunication facilities could be found in a timely manner, any disruption
of these services could have an adverse effect on operating results.

 Comprehensive Income

  The Company has adopted the accounting treatment prescribed by SFAS No. 130,
"Comprehensive Income". FAS No. 130 establishes standards for reporting and
displaying comprehensive income and its components. The adoption of this
statement has not impacted the Company's financial statements as a result of
the Company not having any comprehensive income other than net loss during the
periods presented.

 Segment Reporting

  The Company adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," during 1998. SFAS No. 131 replaces the
"industry segment" approach with the "management" approach. The management
approach designates the internal organization that is used by management for
allocating resources and assessing performance as the source of the Company's
reportable segments. SFAS No. 131 also requires disclosures about products and
services, geographic areas, and major customers. The adoption of SFAS No. 131
did not affect the Company's results of operations or financial position. The
Company operates in one segment, all within the city of Buenos Aires and its
metropolitan area in Argentina.

 Recent Accounting Pronouncements

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 establishes a new model for accounting for derivatives and
hedging activities and supersedes and amends a number of existing standards.
SFAS No. 133 is effective for fiscal years beginning after June 15, 1999, but
earlier application is permitted as of the beginning of any fiscal quarter
subsequent to June 15, 1998. Upon initial application, all derivatives are
required to be

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

recognized in the statement of financial position as either assets or
liabilities and measured at fair value. In addition, all hedging relationships
must be reassessed and documented pursuant to the provisions of SFAS No. 133.
Subsequent to the issuance of SFAS No. 133, the Financial Accounting Standards
Board issued SFAS No. 137, "Accounting for Derivative Instruments and Hedging
Activities--Deferral of the Effective Date of FASB Statement No. 133" ("SFAS
No. 137"), which defers the effective date of SFAS No. 133 to periods beginning
after June 15, 2000. The Company has not committed or expects to commit to any
derivative instrument transactions, and thus does not anticipate that this
pronouncement will have a significant effect on its results.

  In 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use," which is required to be
adopted for fiscal years beginning after December 15, 1998. SOP 98-1 provides
guidance on accounting for the costs of computer software developed or obtained
for internal use, determining whether computer software is for internal use,
and when costs incurred for internal-use computer software are and are not
capitalized. The adoption of SOP 98-1 is not expected to have a material effect
on the Company's financial statements.

  At December 31, 1997 and at September 24, 1998, there were 1,200 Class A
ordinary common stock shares, of $10 par value each, authorized, issued and
outstanding.

  In a Stockholders' meeting held on September 24, 1998, a capital increase was
approved for an amount of $3,926 in connection with the VIA Net.Works, Inc.
purchase of a 51% interest in the Company. The related capital contribution was
made subsequent to September 24, 1998 in exchange for newly issued preferred
stock to VIA NET.WORKS, Inc.. After this increase, outstanding shares were as
follows:

    Class A common shares 1,110 of $0.01 par value each.

    Class B preferred shares 1,155 of $0.01 par value each.

  Preferred shares grant special rights upon liquidation for an amount
equivalent to the $3,926 paid by VIA NET.WORKS, Inc. Additionally, the
preferred shares have voting rights equivalent to the common stock.

  Argentine law requires that 5% of a company's annual net income be
transferred to a legal reserve within stockholders' equity, until such reserve
reaches an amount equivalent to 20% of the Company's capital stock. This
requirement is effectively a restriction on the Company's ability to distribute
a portion of future earnings.

  The Company has established a valuation allowance for net deferred tax assets
of its operations since realization of these benefits cannot be reasonably
assured. These net operating loss carryforwards expire at various future dates
through 2003. While the need for the valuation allowance is subject to periodic
review, if the allowance is reduced, the tax benefit of the carryforwards will
be recorded in future operations as a reduction of the Company's income tax
expense. No cash was paid for income taxes in the year ended December 31, 1997
or the period ended September 24, 1998.

  The Company's net operating loss carry-forwards as of September 24, 1998

  The net operating loss carry-forward of $500 to expire in 2003 results from
the estimated tax loss for the period ended September 24, 1998, which will be
included in the annual income tax return for 1998.

NOTE 8: RELATED PARTY TRANSACTIONS

  During 1996 and 1998, the Company borrowed $16 and $72, respectively, from
its stockholders. At December 31, 1997 and September 24, 1998, the aggregate
outstanding principal balance was $16 and $88, respectively. The loans bear
interest at 4% per annum and have no specified maturity dates. The Company
repaid the loans in 1999.

  In connection with the investment by a VIA NET.WORKS, Inc., it was agreed
that the Company would forgive certain amounts receivable from founding
stockholders, aggregating approximately $90. Such amount is included in
operating expenses for the period ended September 24, 1998 in the accompanying
Statement of Operations.

  At December 31, 1997 and September 24, 1998, the Company held stockholders'
deposits for future capital stock increases in the amount of $380.
Stockholders' deposits for future capital increases represent cash deposits in
anticipation of future conversion into capital stock. The deposits are
considered to represent

stockholders' equity under accounting principles generally accepted in
Argentina. Such deposits are intended to be converted into capital through the
issuance of shares of stock, although the law does not require such a
conversion. Also, until such time, if any, that deposits are converted into
capital, the law does not preclude the stockholder from obtaining a repayment
of the deposit. Therefore, stockholders' deposits aggregating $380 are
presented as current liabilities in the accompanying balance sheet in
accordance with accounting principles generally accepted in the United States.

NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Business Operations

  GTN (also referred to as the "Company") was formed on April 2, 1993 to
operate as an Internet Services Provider (ISP) in the city of Kaarst, Germany.
On October 9, 1998, 51% of the common stock was acquired by VIA NET.WORKS, Inc.
for total consideration of DM 16,533.

 Basis of Presentation

  The Company maintains its accounting records in accordance with generally
accepted accounting principals (GAAP) in the country of Germany. These
financial statements have been prepared in accordance with GAAP in the United
States of America for purposes of filing with the Securities and Exchange
Commission and do not represent the statutory financial statements of the
Company. The accompanying financial statements include the results of the
Company for the year ended December 31, 1997 and for the period from January 1,
1998 to October 9, 1998 (the date that the Company was acquired by VIA
NET.WORKS, Inc.)

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires the Company to make estimates, judgements and
assumptions that affect the reported amounts of assets, liabilities, revenue
and expenses, together with amounts disclosed in the related notes to the
financial statements. Actual results could differ from the recorded estimates.

 Fair Value of Financial Instruments

  Carrying amounts of certain of the Company's financial instruments, including
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses and other liabilities approximate fair value due to their short
maturities. Based upon borrowing rates currently available to the Company for
loans with similar terms, the carrying value of debt approximate their fair
value.

 Cash and Cash Equivalents

  The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.

 Concentration of Credit Risk

  Financial instruments that potentially subject the Company to a concentration
of credit risk consist of cash, cash equivalents, and accounts receivable. The
Company's accounts receivable are derived from revenue earned from customers
located in Germany. The Company performs ongoing credit evaluations of its
customers' financial condition and, generally, requires no collateral from its
customers. The Company maintains an allowance for doubtful accounts receivable
based upon the expected collectibility of accounts receivable.

 Inventory

  Inventory as of December 31, 1997 includes DM 55 of finished goods and is
stated at the lower of cost or market, cost being determined by the specific
identification method.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

               (All amounts in thousands of DM except share data)


 Property and Equipment

  Property and equipment is recorded at cost less accumulated depreciation,
which is provided on the straight-line method over the estimated useful lives
of the assets, generally three to five years. Expenditures for maintenance and
repairs are expensed as incurred.

 Long-Lived Assets

  The Company periodically evaluates the carrying value of property and
equipment to be held and used when events and circumstances warrant such a
review. The carrying value of property and equipment is considered impaired
when the anticipated undiscounted cash flows from the asset is separately
identifiable and is less than its carrying value. In that event, a loss is
recognized based on the amount by which the carrying value exceeds the fair
value of the asset. Fair value is determined primarily using the anticipated
cash flows discounted at a rate commensurate with the risk involved. Losses on
assets to be disposed of are determined in a similar manner, except that fair
values are reduced for the cost to dispose.

 Income Taxes

  The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes". SFAS No. 109 is an asset and liability approach
that requires the recognition of deferred tax assets and liabilities for the
expected future tax consequences attributable to differences between the
carrying amounts of assets and liabilities for financial reporting purposes and
their respective tax bases, and for operating loss and tax credit
carryforwards. In estimating future tax consequences, SFAS No. 109 generally
considers all expected future events other than the enactment of changes in tax
laws or rates.

 Revenue Recognition

  Internet services are recognized as the services are provided. Revenue from
consulting services is recognized as the services are provided. Revenue from
hardware and third-party software sales is recognized upon shipment of the
respective products through October 9, 1998, such sales have been immaterial.
Other revenues include network installation, maintenance and consulting
services. These services are provided on a time-and-material basis and revenue
is recognized based upon time (at established rates) and other direct costs as
incurred.

 Costs of Revenues

  Costs of access revenues primarily consist of telecommunication expenses
inherent in the network infrastructure. Costs of access revenues also include
fees paid for lease of the Company's network infrastructure, product costs, and
contractor fees for operation and support services.

 Sources of Suppliers

  The Company relies on local telephone companies and other companies to
provide data communications. Although management feels alternative
telecommunication facilities could be found in a timely manner, any disruption
of these services could have an adverse effect on operating results.

 Comprehensive Income

  The Company adopted SFAS No. 130, "Comprehensive Income" in 1998. SFAS No.
130 establishes standards for reporting and displaying comprehensive income and
its components. The adoption of this

               (All amounts in thousands of DM except share data)

statement had no impact on the Company's financial statements as a result of
the Company not having any comprehensive income other than net income and loss
during the periods presented.

 Segment Reporting

  The Company adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," during 1998. SFAS No. 131 replaces the
"industry segment" approach with the "management" approach. The management
approach designates the internal organization that is used by management for
allocating resources and assessing performance as the source of the Company's
reportable segments. SFAS No. 131 also requires disclosures about products and
services, geographic areas, and major customers. The adoption of SFAS No. 131
did not affect results of operations or financial position. The Company
operates in one segment, all within the country of Germany.

 Recent Pronouncements

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 establishes a new model for accounting for derivatives and
hedging activities and supersedes and amends a number of existing standards.
SFAS No. 133 is effective for fiscal years beginning after June 15, 1999, but
earlier application is permitted as of the beginning of any fiscal quarter
subsequent to June 15, 1998. Upon initial application, all derivatives are
required to be recognized in the statement of financial position as either
assets or liabilities and measured at fair value. In addition, all hedging
relationships must be reassessed and documented pursuant to the provisions of
SFAS No. 133. Subsequent to the issuance of SFAS No. 133, the Financial
Accounting Standards Board issued SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133" ("SFAS No. 137"), which defers the effective date of SFAS
No. 133 to periods beginning after June 15, 2000. The Company has not committed
or expects to commit to any derivative instrument transactions, and thus does
not anticipate that this pronouncement will have a significant effect on its
results.

  In 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use", which is required to be
adopted for fiscal years beginning after December 15, 1998. SOP 98-1 provides
guidance on accounting for the costs of computer software developed or obtained
for internal use, determining whether computer software is for internal use,
and when costs incurred for internal-use computer software are and are not
capitalized. The adoption of SOP 98-1 is not expected to have a material effect
on the Company's financial statements.

NOTE 3: BORROWINGS

 Lines of Credit

  At October 9, 1998, the Company had a DM 200 line of credit with Commerzbank
Monchengladbach, Germany. Under the line agreement, borrowings are secured by
personal guarantees of the shareholders, assignment of accounts receivable, a
subordination agreement by all shareholders and a pledge of security accounts
owned by shareholders. The line of credit expired March 31, 1999 and charged
interest at a rate of 7.5% per annum. Under the line of credit, the Company was
restricted from paying dividends as long as the equity ratio was less than 20%
and the ratio of fixed assets to equity was less than 100%. Dividends may be
paid if they are immediately deposited as shareholders' loans. At October 9,
1998, there was no outstanding principal or interest.

  At October 9, 1998, the Company had DM 274 outstanding under a line of credit
with Raiffeisenbank Kaarst/Germany. The line of credit which has been agreed in
writing provides for borrowings of up to DM 160, which are secured by personal
guarantees of shareholders and pledge of security accounts owned by
shareholders. The line of credit originally expired in 1997 but is revolving
and charges interest at a rate of 7.75% per annum. Borrowings in excess of DM
160 are overdraft facilities granted without written contract.

  At December 31, 1997 the Company had DM 67 outstanding under the above
mentioned line of credit.

NOTE 4: COMMITMENTS

 Leases

  The Company leases office space and equipment under noncancelable operating
leases with various expiration dates through May 2003. Rent expense for the
year ended December 31, 1997 and period ended October 9, 1998 was DM 232 and DM
243, respectively. The terms of the facility lease provide for rental payments
increased at 2.5% per year. The Company recognizes rent expense on a straight-
line basis over the lease period, and has accrued for rent expense incurred but
not paid. Future minimum lease payments under noncancelable operating leases,
including lease commitments entered into subsequent to October 9, 1998 as
follows:

year ended July 31, 1997 and 1998 and for the period from August 1, 1998 to
October 29, 1998 (the date that the Company was acquired by VIA NET.WORKS,
Inc.)

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires the Company to make estimates, judgements and
assumptions that affect the reported amounts of assets, liabilities, revenue
and expenses, together with amounts disclosed in the related notes to the
financial statements. Actual results could differ from the recorded estimates.

 Fair Value of Financial Instruments

  Carrying amounts of certain of the Company's financial instruments, including
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses and other liabilities approximate fair value due to their short
maturities. Based upon borrowing rates currently available to the Company for
loans with similar terms, the carrying value of debt and capital lease
obligations approximate fair value.

 Cash and Cash Equivalents

  The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.

 Concentration of Credit Risk

  Financial instruments that potentially subject the Company to a concentration
of credit risk consist of cash, cash equivalents, short-term investments and
accounts receivable. The Company's accounts receivable are derived from revenue
earned from customers located in the United Kingdom. The Company performs
ongoing credit evaluations of its customers' financial condition and,
generally, requires no collateral from its customers. The Company maintains an
allowance for doubtful accounts receivable based upon the expected
collectibility of accounts receivable.

 Property and Equipment

  Property and equipment is recorded at cost less accumulated depreciation,
which is provided on the straight-line method over the estimated useful lives
of the assets, generally three to five years. Cost includes major expenditures
for improvements and replacements which extend useful lives or increase
capacity of the

asset and interest costs associated with significant capital additions.
Expenditures for maintenance and repairs are expensed as incurred.

  Costs for internal use software are expensed as incurred.

 Long-Lived Assets

  The Company periodically evaluates the carrying value of property and
equipment to be held and used when events and circumstances warrant such a
review. The carrying value of property and equipment is considered impaired
when the anticipated undiscounted cash flows from the asset is separately
identifiable and is less than its carrying value. In that event, a loss is
recognized based on the amount by which the carrying value exceeds the fair
value of the asset. Fair value is determined primarily using the anticipated
cash flows discounted at a rate commensurate with the risk involved. Losses on
assets to be disposed of are determined in a similar manner, except that fair
values are reduced for the cost to dispose.

 Advertising Costs

  Costs related to advertising and promotion of services are charged to sales
and marketing expense as incurred. Advertising expense was (Pounds)22,
(Pounds)133 and (Pounds)108 for the period ended October 29, 1998 and the years
ended July 31, 1998 and 1997, respectively.

 Income Taxes

  The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes". SFAS No. 109 is an asset and liability approach
that requires the recognition of deferred tax assets and liabilities for the
expected future tax consequences attributable to differences between the
carrying amounts of assets and liabilities for financial reporting purposes and
their respective tax bases, and for operating loss and tax credit
carryforwards. In estimating future tax consequences, SFAS No. 109 generally
considers all expected future events other than the enactment of changes in tax
laws or rates.

 Revenue Recognition

  Revenue from Internet connectivity and enhanced Internet services are
recognized as the services are provided, net of Value Added Tax and trade
discounts. Income from subscriptions is recognized ratably over the
subscriptions term, generally a twelve month period. The Company records
deferred revenue for amounts billed and/or collected in advance.

 Costs of Revenues

  Costs of access revenues primarily consist of telecommunication expenses
inherent in the network infrastructure. Costs of access revenues also include
fees paid for lease of the Company's network infrastructure, as well as license
fees for web browser software based on a per-user charge, other license fees
paid to third-party software vendors, product costs, and contractor fees for
operation and support services.

 Sources of Suppliers

  The Company relies on local telephone companies and other companies to
provide data communications. Although management feels alternative
telecommunication facilities could be found in a timely manner, any disruption
of these services could have an adverse effect on operating results.

 Comprehensive Income

  The Company adopted SFAS No. 130, "Comprehensive Income," in 1998. SFAS No.
130 establishes standards for reporting and displaying comprehensive income and
its components. The adoption of this statement had no impact on the Company's
financial statements as a result of the Company not having any comprehensive
income other than net loss during the periods presented.

 Segment Reporting

  The Company adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," during 1998. SFAS No. 131 replaces the
"industry segment" approach with the "management" approach. The management
approach designates the internal organization that is used by management for
allocating resources and assessing performance as the source of the Company's
reportable segments. SFAS No. 131 also requires disclosures about products and
services, geographic areas, and major customers. The adoption of SFAS No. 131
did not affect results of operations or financial position. The Company
operates in one segment, all within the United Kingdom.

 Recent Pronouncements

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 establishes a new model for accounting for derivatives and
hedging activities and supersedes and amends a number of existing standards.
SFAS No. 133 is effective for fiscal years beginning after June 15, 1999, but
earlier application is permitted as of the beginning of any fiscal quarter
subsequent to June 15, 1998. Upon initial application, all derivatives are
required to be recognized in the statement of financial position as either
assets or liabilities and measured at fair value. In addition, all hedging
relationships must be reassessed and documented pursuant to the provisions of
SFAS No. 133. Subsequent to the issuance of SFAS No. 133, the Financial
Accounting Standards Board issued SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133" ("SFAS No. 137"), which defers the effective date of SFAS
No. 133 to periods beginning after June 15, 2000. The Company has not committed
or expects to commit to any derivative instrument transactions, and thus does
not anticipate that this pronouncement will have a significant effect on its
results.

  In 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-1, Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use, which is required to be
adopted for fiscal years beginning after December 15, 1998. SOP 98-1 provides
guidance on accounting for the costs of computer software developed or obtained
for internal use, determining whether computer software is for internal use,
and when costs incurred for internal-use computer software are and are not
capitalized. The adoption of SOP 98-1 is not expected to have a material effect
on the Company's financial statements.

                       Report of Independent Accountants


April 9, 1999

To the Board of Directors and
Stockholders of Dialdata S.A., Internet Systems

In our opinion, the accompanying balance sheets and the related statements of
operations, changes in stockholders' equity, and of cash flows expressed in
U.S. dollars, present fairly, in all material respects, the financial position
of Dialdata S.A. Internet Systems at December 29, 1998 (date of acquisition)
and December 31, 1997 and the results of its operations and its cash flows for
the period from January 1, 1998 to December 29, 1998 and the year ended
December 31, 1997, in conformity with accounting principles generally accepted
in the United States of America. 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 of these statements in accordance with generally accepted auditing
standards in Brazil which are substantially similar to generally accepted
auditing standards in the United States of America, which 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, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

                (In thousands of US dollars, except share data)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Business Operations
 -------------------
  Dial-Data Informatica e Assessoria Ltda. ("the Company") was formed on
February 1, 1993, to operate as an Internet service provider (ISP) in Brazil.
On December 29, 1998, 51% of the common stock was acquired by V-I-A Internet
Holdings Brasil Ltda. for total consideration of $5,996, and the name of the
Company changed to Dialdata S.A. Internet Systems.

  At the same date, a further 30,990 newly authorized shares were subscribed by
V-I-A Internet Holdings Brasil Ltda. and will be paid-up in installments
totaling R$5,158 thousand (equivalent to US$3,750 on that date) during 1999.

 Basis Of Presentation
 ---------------------
  The Company maintains its accounting records in Brazilian reais in accordance
with generally accepted accounting principals (GAAP) in Brazil. These financial
statements have been prepared in U.S. dollars and in accordance with GAAP in
the United States of America for purposes of filing with the Securities and
Exchange Commission and do not represent the statutory financial statements of
the Company. The accompanying financial statements include the results of the
Company for the period ended December 29, 1998 and the year ended December 31,
1997.

  For the year ended December 31, 1997 Brazil was a hyperinflationary economy,
defined as having cumulative inflation in excess of 100% for the prior three-
year period. In accordance with United States GAAP for companies operating in a
hyperinflationary economy, the functional currency of the company for purposes
of remeasuring the local currency under Financial Accounting Standards
Statement 52 (SFAS 52) was the U.S. dollar. Consequently, non-monetary assets
and liabilities and stockholders' equity were translated at historical exchange
rates, all other assets and liabilities being translated at the year-end
exchange rate. The statements of operations and cash flows, except for
depreciation, have been translated at the average monthly exchange rate.

  As of January 1, 1998 Brazil was no longer considered to be a
hyperinflationary economy. Accordingly, as of and for the period ended December
29, 1998 the functional currency is the Brazilian real and the financial
statements have therefore been translated into U.S. dollars using the average
exchange rate for the period for the statements of operations and cash flows
and using the period-end rate for assets and liabilities. The adjustment at
January 1, 1998 to reflect the change in the functional currency and the
translation adjustment arising during the period are shown in accumulated other
comprehensive income.

 Use Of Estimates
 ----------------
  The preparation of financial statements in conformity with generally accepted
accounting principles requires the Company to make estimates, judgements and
assumptions that affect the reported amounts of assets, liabilities, revenue
and expenses, together with amounts disclosed in the related notes to the
financial statements. Actual results could differ from the recorded estimates.

 Fair Value Of Financial Instruments
 -----------------------------------
  Carrying amounts of certain of the Company's financial instruments, including
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses and other liabilities approximate fair value due to their short
maturities.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

                (In thousands of US dollars, except share data)


 Cash And Cash Equivalents
 -------------------------
  The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.

 Concentration Of Credit Risk
 ----------------------------
  Financial instruments that potentially subject the Company to a concentration
of credit risk consist of cash, cash equivalents, short-term investments and
accounts receivable. The Company's accounts receivable are derived from revenue
earned from customers located in Brazil. The Company performs ongoing credit
evaluations of its customers' financial condition and requires no collateral
from its customers.

 Property And Equipment
 ----------------------
  Property and equipment is recorded at cost less accumulated depreciation,
which is provided on the straight-line method over the estimated useful lives
of the assets, generally five to ten years. Cost includes major expenditures
for improvements and replacements which extend useful lives or increase
capacity of the asset and interest costs associated with significant capital
additions. Expenditures for maintenance and repairs are expensed as incurred.
Leasehold improvements include costs associated with telecommunications
equipment, installations and building improvements.

  Long-Lived Assets
  -----------------
  The Company periodically evaluates the carrying value of property and
equipment to be held and used when events and circumstances warrant such a
review. The carrying value of property and equipment is considered impaired
when the anticipated undiscounted cash flows from the asset is separately
identifiable and is less than its carrying value. In that event, a loss is
recognized based on the amount by which the carrying value exceeds the fair
value of the asset. Fair value is determined primarily using the anticipated
cash flows discounted at a rate commensurate with the risk involved. Losses on
assets to be disposed of are determined in a similar manner, except that fair
values are reduced for the cost to dispose.

 Advertising Costs
 -----------------
  Costs related to advertising and promotion of services are charged to sales
and marketing expense as incurred. Advertising expenses for all periods were
not significant.

 Income Taxes
 ------------
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109 (SFAS No. 109), "Accounting for Income
Taxes". SFAS No. 109 is an asset and liability approach that requires the
recognition of deferred tax assets and liabilities for the expected future tax
consequences attributable to differences between the carrying amounts of assets
and liabilities for financial reporting purposes and their respective tax
bases, and for operating loss and tax credit carryforwards. In estimating
future tax consequences, SFAS No. 109 generally considers all expected future
events other than the enactment of changes in tax laws or rates.

 Revenue Recognition
 -------------------
  Revenue from Internet and consulting services is recognized as the services
are provided. Revenue also includes network installation, maintenance and
consulting services. These services are provided on a time-and-

                                      F-72

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

                (In thousands of US dollars, except share data)

material basis and revenue is recognized based upon time (at established rates)
and other direct costs as incurred.

 Costs of Revenues
 -----------------
  Costs of access revenues primarily consists of telecommunication expenses
inherent in the network infrastructure, which are recognized on the accrual
basis.

 Sources of Suppliers
 --------------------
  The Company relies on local telephone companies and other companies to
provide data communications. Although management feels alternative
telecommunication facilities could be found in a timely manner, any disruption
of these services could have an adverse effect on operating results.

 Comprehensive Income
 --------------------
  The Company adopted the accounting treatment prescribed by SFAS No. 130,
"Comprehensive Income", in 1998. SFAS No. 130 establishes standards for
reporting and displaying comprehensive income and its components. Comprehensive
income consists of net income and foreign currency translation adjustments as
presented in the statement of operations and other comprehensive loss. The
adoption of SFAS No. 130 had no impact on total stockholders' equity or net
income.

 Segment Reporting
 -----------------
  The Company adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," during 1998. SFAS No. 131 replaces the
"industry segment" approach with the "management" approach. The management
approach designates the internal organization that is used by management for
allocating resources and assessing performance as the source of the Company's
reportable segments. SFAS No. 131 also requires disclosures about products and
services, geographic areas, and major customers. The adoption of SFAS No. 131
did not affect results of operations or financial position. The Company
operates in one segment, all within the country of Brazil.

 Recent Accounting Pronouncements
 --------------------------------
  In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") 98-1, "Accounting for the Costs
of Computer Software Developed or Obtained for Internal Use", which is required
to be adopted for fiscal years beginning after December 15, 1998. SOP 98-1
provides guidance on accounting for the costs of computer software developed or
obtained for internal use, determining whether computer software is for
internal use, and when costs incurred for internal-use computer software are
and are not capitalized. The adoption of SOP 98-1 is not expected to have a
material effect on the Company's financial statements.

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 establishes a new model for accounting for derivatives and
hedging activities and supersedes and amends a number of existing standards.
SFAS No. 133 is effective for fiscal years beginning after June 15, 1999, but
earlier application is permitted as of the beginning of any fiscal quarter
subsequent to June 15, 1998. Upon initial application, all derivatives are
required to be recognized in the statement of financial position as either
assets or liabilities and measured at fair value. In

addition, all hedging relationships must be reassessed and documented pursuant
to the provisions of SFAS No. 133. Subsequent to the issuance of SFAS No. 133,
the Financial Accounting Standards Board issued SFAS No. 137, "Accounting for
Derivative Instruments and Hedging Activities--Deferral of the Effective Date
of FASB Statement No. 133" ("SFAS No. 137"), which defers the effective date of
SFAS No. 133 to periods beginning after June 15, 2000. The Company has not
committed or expects to commit to any derivative instrument transactions, and
thus does not anticipate that this pronouncement will have a significant effect
on its results.

  Brazilian tax law provides an alternative income tax and social contribution
computation method for small businesses that are wholly-owned by Brazilian
residents, referred to as the presumed profits method. The Company employed the
presumed profits method for calculating its income taxes and social
contribution and as a result there were no temporary differences that would
give rise to deferred tax assets or liabilities. Accordingly, as of December
31, 1997 and December 29, 1998, the Company had no deferred tax assets nor
deferred tax liabilities. Also as a result of this option, the effective tax
rate was 27% compared with a standard tax rate of 33%.

5. SUBSEQUENT EVENTS

 Devaluation of local currency

  On January 15, 1999, the Brazilian Central Bank decided to abandon the
foreign exchange rate controls which were then in force. As a result of this
decision and of the market reaction, the Brazilian real was immediately and
significantly devalued, having traded stable since then. On April 9, 1999 the
closing exchange rate was US$1 : R$1.71, equivalent to an accumulated
devaluation of approximately 40% from December 31, 1998.

  Given that no prediction can be made of the future trend of the exchange
rate, of its effects on suppliers' prices and of the market's capacity to
absorb price increases, it is not possible to estimate the final effects of
these events on the company's future operations. From an immediate financial
perspective, the real devaluation had no significant impact on the Company's
cash flows, as no major U.S. dollar or other foreign currency denominated
balances existed at the devaluation date.

                       Report of Independent Accountants

To the Board of Directors and Stockholders of
I-Way Limited

  In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of stockholders' equity (deficit) and of
cash flows expressed in British Pounds, present fairly, in all material
respects, the financial position of I-Way Limited as of April 30, 1997 and
1998, and December 31, 1998, and the results of its operations and its cash
flows for each of the two years in the period ended April 30, 1998, and the
period from May 1, 1998 to December 31, 1998, in conformity with generally
accepted accounting principles in the United States of America. 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 of these financial statements in accordance
with generally accepted auditing standards in the United Kingdom which are
substantially similar to generally accepted auditing standards in the United
States of America which 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, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

       (All amounts in thousands of GBP, except share and per share data)

NOTE 1: SUMMARY OF SIGNIFICANT POLICIES

 Business Operations

  I-Way Limited ("the Company") was formed on March 6, 1995 and commenced
operation as an internet service provider (ISP) on May 1, 1995 in Reading,
United Kingdom. On June 18, 1998, 36% of the Company's outstanding stock was
acquired by VIA NET.WORKS, Inc., a company incorporated in the USA for
approximately (Pounds)1,347. On August 5, 1999 VIA NET.WORKS, Inc. acquired the
remainder of the Company's outstanding stock for (Pounds)8,078.

 Basis of Presentation

  The Company maintains its accounting records in accordance with generally
accepted accounting principles (GAAP) in the United Kingdom. These financial
statements have been prepared in accordance with GAAP in the United States for
purposes of filing with the Securities and Exchange Commission and do not
represent the statutory financial statements of the Company. The accompanying
consolidated financial statements include the results of the Company for the
year ended April 30, 1997 and 1998 and for the periods from May 1, 1998 to
December 31, 1998, January 1, 1998 to June 30, 1998 (unaudited) and January 1,
1999 to June 30, 1999 (unaudited).

 Principles of Consolidation

  The accompanying consolidated financial statements include the accounts of
the Company and its wholly-owned subsidiary, I-way Oxford Limited. All
significant intercompany accounts and transactions have been eliminated on
consolidation.

 Interim Financial Information (Unaudited)

  Interim financial information for the six months ended June 30, 1998 and 1999
included herein is unaudited. However, the Company believes that interim
financial information includes all adjustments, consisting of only normal
recurring adjustments, necessary for a fair presentation of the results of
interim periods. The results of operations for the six months ended June 30,
1999 are not necessarily indicative of the results to be expected for the year
ending December 31, 1999.


 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires the Company to make estimates, judgements and
assumptions that affect the reported amounts of assets, liabilities, revenue
and expenses, together with amounts disclosed in the related notes to the
financial statements. Actual results could differ from the recorded estimates.

 Fair Value of Financial Instruments

  Carrying amounts of certain of the Company's financial instruments, including
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses and other liabilities approximate fair value due to their short
maturities. Based upon borrowing rates currently available to the Company for
loans with similar terms, the carrying value of debt and capital lease
obligations approximate their fair value.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

       (All amounts in thousands of GBP, except share and per share data)


 Cash and Cash Equivalents

  The Company maintains its cash accounts at a major financial institution and
has not experienced any losses on its cash deposits as of December 31, 1998.
The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.

 Concentration of Credit Risk

  Financial instruments that potentially subject the Company to a concentration
of credit risk consist of cash, cash equivalents, short-term investments and
accounts receivable. The Company's accounts receivable are derived from revenue
earned from customers located in the United Kingdom. The Company performs
ongoing credit evaluations of its customers' financial condition and,
generally, requires no collateral from its customers. The Company maintains an
allowance for doubtful accounts receivable based upon the expected
collectibility of accounts receivable.

  At April 30, 1997 one customer represented 19% of accounts receivables.
During the year ended April 30, 1998 one customer represented 11% of the
Company's consolidated revenues.


 Property and Equipment

  Property and equipment is recorded at cost less accumulated depreciation,
which is provided on the straight-line method over the estimated useful lives
of the assets, generally a three-year period. Cost includes major expenditures
for improvements and replacements, which extend usefulness or increase capacity
of the asset and interest costs associated with significant capital additions.
Expenditures for maintenance and repairs are expensed as incurred. When
property or equipment is retired or otherwise disposed of, the cost and
accumulated depreciation are removed from the appropriate accounts, with the
resulting gain or loss included in current operations.

  The costs of internal use software are expensed as incurred.

 Intangible Assets

  Intangible assets represent the goodwill arising from the purchase of I-Way
Oxford Limited in October 1997. This balance represents the difference between
the fair value of the assets acquired and the fair value of consideration given
on the date of purchase. Intangible assets are recorded at cost less
accumulated amortization over the estimated useful economic lives of the
assets, generally a three-year period.

 Long-Lived Assets

  The Company periodically evaluates the carrying value of property and
equipment to be held and used when events and circumstances warrant such a
review. The carrying value of property and equipment is considered impaired
when the anticipated undiscounted cash flows from the asset is separately
identifiable and is less than its carrying value. In that event, a loss is
recognized based on the amount by which the carrying value exceeds the fair
value of the asset. Fair value is determined primarily using the anticipated
cash flows discounted at a rate commensurate with the risk involved. Losses on
assets to be disposed of are determined in a similar manner, except that fair
values are reduced for the cost to dispose.

       (All amounts in thousands of GBP, except share and per share data)


 Advertising Costs

  Costs related to advertising and promotion of services is charged to
operating expense as incurred. Advertising expense was (Pounds)42, (Pounds)43,
and (Pounds)71 for the years ended April 30, 1997 and 1998, and the period from
May 1, 1998 to December 31, 1998, respectively.

 Income Taxes

  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS
No. 109"). SFAS No. 109 is an asset and liability approach that requires the
recognition of deferred tax assets and liabilities for the expected future tax
consequences attributable to differences between the carrying amounts of assets
and liabilities for financial reporting purposes and their respective tax
bases, and for operating loss and tax credit carryforwards. In estimating
future tax consequences, SFAS No. 109 generally considers all expected future
events other than the enactment of changes in tax laws or rates.

  The Company provides a valuation allowance against net deferred tax assets
if, based upon available evidence, it is more likely than not that some or all
of the deferred tax assets may not be realized.

 Revenue Recognition

  Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance.

  Revenue from consulting services is recognized as the services are provided.
Revenue from third party hardware and software re-sales is recognized upon
shipment of the respective products. Through December 31, 1998, such sales have
been immaterial. Other revenues include network installation and maintenance.
These services are provided on a time-and-material basis and revenue is
recognized based upon time (at established rates) and other direct costs as the
services are provided.

 Costs of Revenues

  Costs of revenues consist primarily of telecommunication expenses inherent in
the network infrastructure. Costs of revenues also includes license fees for
software, third-party Web designers, product costs, and contractor fees for
operation and support services.

 Sources of Suppliers

  The Company relies on local telephone companies and other companies to
provide data communications. Although management feels alternative
telecommunication facilities could be found in a timely manner, any disruption
of these services could have an adverse effect on operating results.

 Comprehensive Income

  The Company adopted Statement of Financial Accounting Standards No. 130,
"Reporting Comprehensive Income" ("SFAS No. 130"), in 1998. SFAS No. 130
establishes standards for reporting and displaying comprehensive income and its
components. Comprehensive income consists of net income as presented in the
consolidated statements of income. The adoption of SFAS No. 130 had no impact
on the Company's financial statements as a result of the Company not having any
comprehensive income other than net loss during the periods presented.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

       (All amounts in thousands of GBP, except share and per share data)


 Segment Reporting

  The Company adopted Statement of Financial Accounting Standard No. 131,
"Disclosures about Segments of an Enterprise and Related Information" ("SFAS
No. 131"), during 1998. SFAS No. 131 replaces the "industry segment" approach
with the "management" approach. The management approach designates the internal
organization that is used by management for allocating resources and assessing
performance as the source of the Company's reportable segments. SFAS No. 131
also requires disclosures about products and services, geographic areas, and
major customers. The adoption of SFAS No. 131 did not affect results of
operations or financial position. The Company operates in one segment, all
within the United Kingdom.

 Recent Accounting Pronouncements

  In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") No. 98-1, "Software for Internal Use," which
provides guidance on accounting for the cost of computer software developed or
obtained for internal use. SOP No. 98-1 is effective for financial statements
for fiscal years beginning after December 15, 1998. The early adoption of SOP
98-1 did not have a material effect on the Company's financial statements.

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 establishes a new model for accounting for derivatives and
hedging activities and supersedes and amends a number of existing standards.
SFAS No. 133 is effective for fiscal years beginning after June 15, 1999, but
earlier application is permitted as of the beginning of any fiscal quarter
subsequent to June 15, 1998. Upon initial application, all derivatives are
required to be recognized in the statement of financial position as either
assets or liabilities and measured at fair value. In addition, all hedging
relationships must be reassessed and documented pursuant to the provisions of
SFAS No. 133. Subsequent to the issuance of SFAS No. 133, the Financial
Accounting Standards Board issued SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133" ("SFAS No. 137"), which defers the effective date of SFAS
No. 133 to periods beginning after June 15, 2000. The Company has not committed
or expects to commit to any derivative instrument transactions, and thus does
not anticipate that this pronouncement will have a significant effect on its
results.

 Capital Leases

  At April 30, and December 31, 1998, the Company had (Pounds)81 and (Pounds)66
outstanding and due under capital lease agreements with Lombard Network
Services. The assets held under these capital lease agreements comprise
machinery and equipment, and fixtures and fittings. Future minimum lease
payments under non-cancelable capital leases, including lease commitments
entered into subsequent to December 31, 1998 were settled during 1999. These
amounted to payments of (Pounds)68, including interest of (Pounds)2.

NOTE 4: BANK OVERDRAFT

  Short-term debt consists of bank overdrafts at April 30, 1998. The bank
overdrafts accrued interest at a rate of 2.5% per annum above the bank's base
rate and are repayable on demand.

  Interest expense for the year ended April 30, 1998 was (Pounds)2.

NOTE 5: STOCKHOLDERS' EQUITY

  At April 30, 1998, and 1997, there were 100,000 6% preferred stock shares
authorized, of which 50,000 shares were issued and outstanding.

  In the period ended December 31, 1998 the Company redeemed 50,000 shares of
6% preferred stock, and the 100,000 6% preferred stock shares authorized were
cancelled. On the same date two new classes of preferred stock shares were
created being 26,789 Series A convertible preferred shares of (Pounds)1 each
and 23,211 Series B convertible preferred shares of (Pounds)1 each. 26,789 of
the Series A shares were then issued and remain outstanding.

  The 6% preferred stock shares were entitled to a 6% dividend, payable in
arrears and only when the company has available distributable profits. Rights
to unpaid dividends were waived when these shares were redeemed.

  The preferred Series A and B convertible shares participate in all dividends
payable to holders of the ordinary shares as if all preferred shares had been
converted into ordinary shares. Any holders of preferred

shares may convert all or any portion of the preferred shares into a number of
fully paid ordinary shares. On winding up the holders have priority before all
other classes of shares to receive repayment of capital plus any arrears of
dividend. The holders have voting rights at general meetings, one vote per
share.

</TABLE>

  The Company has established a valuation allowance for net deferred tax assets
of its operations since realization of these benefits cannot be reasonably
assured. While the need for the valuation allowance is subject to periodic
review, if the allowance is reduced, the tax benefits of the carryforwards will
be recorded in future operations as a reduction of the Company's income tax
expense. No cash was paid for income taxes in the years ended April 30, 1997
and 1998, or the period ended December 31, 1998.

  Net operating losses for tax purposes can be carried forward indefinitely for
offset against future taxable income.

To the Stockholders of bART Holding B.V.,

In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, stockholders'deficit and of cash flows
expressed in Dutch guilders present fairly, in all material respects, the
financial position of bART Holding B.V. and its subsidiaries at December 31,
1998, and the results of their operations and their cash flows for the year
then ended in conformity with generally accepted accounting principles in the
United States of America. These financial statements are the responsibility of
the Company's management; our responsibility is to express an opinion on these
financial statements based on our audit. We conducted our audit of these
statements in accordance with generally accepted auditing standards in the
Netherlands which are substantially similar to generally accepted auditing
standards in the United States of America which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for the
opinion expressed above.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Organization and Nature of Operation

  bART Holding B.V. ("the Company", "bART"), formerly Anjantus Altissima was
incorporated on August 26, 1996 to operate as an Internet service provider
("ISP").

  On March 25, 1999, the Company was acquired by VIA NET.WORKS, Inc. for
NLG 13,450.

  At December 31, 1998, bART Holding B.V. is the parent company of the wholly
owned subsidiaries: Arameta B.V., Xenovic B.V., bART Noord Nederland B.V., bART
Midden Nederland B.V., and bART Den Haag B.V.("bART Internet Services").

 Basis of Presentation

  These financial statements have been prepared in accordance with generally
accepted accounting principles in the United States of America for purposes of
inclusion into the filing of VIA NET.WORKS, Inc. with the Securities and
Exchange Commission and do not represent the statutory financial statements of
the Company. The accompanying financial statements include the results of the
Company for the year ended December 31, 1998.

 Principles of Consolidation

  The accompanying consolidated financial statements include the accounts of
the Company and its majority-owned and controlled subsidiaries. All significant
intercompany balances and transactions have been eliminated in consolidation.

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles in the United States of America requires management to
make estimates, judgements and assumptions that affect the reported amounts of
assets and liabilities, revenues and expenses, together with the amounts
disclosed in the related notes to the financial statements. Actual results
could differ from these estimates.

 Fair Value of Financial Instruments

  Carrying amounts of certain of the Company's financial instruments, including
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses and other liabilities approximate fair value due to their short
maturities. Based upon borrowing rates currently available to the Company for
loans with similar terms, the carrying value of debt and capital lease
obligations approximate their fair value.

 Cash and Cash Equivalents

  The Company considers all highly liquid debt instruments purchased with an
original maturity of three months or less to be cash equivalents.

 Concentration of Credit Risk

  Financial instruments that potentially subject the Company to significant
concentration of credit risk consist primarily of cash, cash equivalents, and
accounts receivable. Accounts receivable are typically unsecured and are
derived from revenues earned from customers located in the Netherlands. The
Company

                               bART HOLDING B.V.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

          (In thousands of NLG, except share data and per share data)

performs ongoing credit evaluations of its customers' financial condition and,
generally, requires no collateral from its customers. The Company maintains an
allowance for doubtful accounts receivable based upon the expected
collectibility of accounts receivable. At December 31, 1998, no one customer
accounted for 10% or more of the accounts receivable balance.

 Property and Equipment

  Property and equipment are stated at cost less accumulated depreciation,
which is recorded on the straight-line method over the estimated useful lives
of the assets, generally three to five years.

  Costs capitalized include major expenditures for improvements which extend
useful lives or increase capacity of the asset and interest costs associated
with significant capital additions. Expenditures for maintenance and repairs
are expensed as incurred. Leasehold improvements include costs associated with
telecommunications equipment installations and building improvements.

  Gains or losses on the disposal of property and equipment are included in
income and the related costs and accumulated depreciation are removed from the
accounts.

  The Company finances part of its data communications equipment and other
fixed assets under capital lease agreements. The assets and liabilities under
capital leases are recorded at the lesser of the present value of aggregate
future minimum lease payments, including estimated bargain purchase options, or
the fair value of the asset under lease. Assets under these capital leases are
depreciated over the terms of the related leases.

 Long-Lived Assets

  The Company periodically evaluates the carrying value of property and
equipment to be held and used when events and circumstances warrant such a
review. The carrying value of property and equipment is considered impaired
when the anticipated undiscounted cash flows from the asset is separately
identifiable and is less than its carrying value. In that event, a loss is
recognized based on the amount by which the carrying value exceeds the fair
value of the asset. Fair value is determined primarily using the anticipated
cash flows discounted at a rate commensurate with the risk involved. Losses on
assets to be disposed of are determined in a similar manner, except that fair
values are reduced for the cost to dispose.

 Income Taxes

  The Company accounts for income taxes under SFAS No. 109, "Accounting for
Income Taxes". SFAS 109 is an asset and liability approach that requires the
recognition of deferred tax assets and liabilities for the expected future tax
consequences attributable to differences between carrying amounts of assets and
liabilities for financial reporting purposes and their respective tax bases,
and for operating loss and tax credit carry forwards. Valuation allowances are
established on deferred tax assets when management estimates that it is more
likely than not that the related benefit will not be realised.

 Stock-Based Compensation

  The Company accounts for stock-based compensation in accordance with the
provisions of Accounting Principles Board (APB) No. 25, "Accounting for Stock
Issued to Employees" and complies with the disclosure provisions of Statement
of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation.". Under APB 25, compensation cost is recognised over the vesting
period based on the differences if any, on the date of the grant between the
fair value of the Company's stock and the exercise price.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

          (In thousands of NLG, except share data and per share data)

 Revenue Recognition

  Internet services are recognised as the services are provided. The Company
records deferred revenue for amounts billed in advance of the service that is
provided.

  The Company provides consulting services. Revenue from these services is
recognized as the services are provided.

 Costs of Revenues

  Costs of access revenues primarily consist of telecommunication expenses
inherent in the network infrastructure. Costs of access revenues also include
fees paid for lease of the network infrastructure, as well as license fees for
Web browser software based on a per-user charge, other license fees paid to
third-party software vendors, product costs, and contractor fees for operation
and support services. Discounts received are set against the related expenses.

 Sources of Suppliers

  The Company relies on local telephone companies and other companies to
provide data communications. Although management feels alternative
telecommunications facilities could be found in a timely manner, any disruption
of these services could have an adverse effect on operating results.

 Recently Issued Accounting Pronouncements

  In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued a Statement of Position ("SOP") 98-1, Accounting for the Costs
of Computer Software Developed or Obtained for Internal Use, and SOP 98-5,
Reporting on the Costs of Start-Up Activities, both of which are required to be
adopted for fiscal years beginning under December 15, 1998. SOP 98-1 provides
guidance on accounting for the costs of computer software developed or obtained
for internal use, determining whether computer software is for internal use,
and when costs incurred for internal-use computer software are and are not
capitalised. SOP 98-5 requires costs of start-up activities and organisation
costs to be expensed as incurred. The adoption of SOP 98-1 and SOP 98-5 would
not have a material effect on the Company's consolidated financial statements.

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 establishes a new model for accounting for derivatives and
hedging activities and supersedes and amends a number of existing standards.
SFAS No. 133 is effective for fiscal years beginning after June 15, 1999, but
earlier application is permitted as of the beginning of any fiscal quarter
subsequent to June 15, 1998. Upon initial application, all derivatives are
required to be recognized in the statement of financial position as either
assets or liabilities and measured at fair value. In addition, all hedging
relationships must be reassessed and documented pursuant to the provisions of
SFAS No. 133. Subsequent to the issuance of SFAS No. 133, the Financial
Accounting Standards Board issued SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133" ("SFAS No. 137"), which defers the effective date of SFAS
No. 133 to periods beginning after June 15, 2000. The Company has not committed
or expects to commit to any derivative instrument transactions, and thus does
not anticipate that this pronouncement will have a significant effect on its
results.

 Segment Reporting

  The Company adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information" during 1998. SFAS No. 131 replaces the
"industry segment" approach with the "management"

                                      F-94

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

          (In thousands of NLG, except share data and per share data)

approach. The management approach designates the internal organisation that is
used by management for allocating resources and assessing performance as the
source of the Company's reportable segments. SFAS No. 131 also requires
disclosure about products and services, geographic areas, and major customers.
The adoption of SFAS No. 131 did not affect results of operations or financial
position. The Company operates in one segment, all within the country of the
Netherlands.

2. PROPERTY AND EQUIPMENT

  Property and equipment at December 31, 1998 consists of the following:

6. RELATED PARTY TRANSACTIONS

  In 1998, a loan from the stockholders of NLG 500 was given to the Company
which had an interest rate of 6%. The purpose of the loan was for immediate
cash needs. The interest expense for the year ended December 31, 1998 was NLG
14.

  These loans were repaid subsequent to year end.

  During the year ended December 31, 1998, management fees of NLG 462 were paid
to former stockholders of the Company, Goede Paard B.V. and Conew B.V.

7. INCOME TAXES

  The Company has a deferred tax asset which consists of net operating loss
carryforwards of NLG 6,777. These net operating loss carryforwards have an
indefinite life. While this tax position is subject to periodic review, the tax
benefits of the carry forwards will be recorded in the future operations as a
reduction of the Company's income tax expense.

  During the year ended December 31, 1998, there were not any net operating
losses utilised in the current year as the entities did not have any profit.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

          (In thousands of NLG, except share data and per share data)


  A 100% valuation allowance has been provided against the deferred tax asset
as the Company has determined that it is not likely that these amounts will be
realized in the future. The Company will continue to review this valuation
allowance and make adjustments when and if deemed appropriate.

8. EXTRAORDINARY ITEM

  During 1998, the Company negotiated a settlement with certain of its trade
creditors. The settlement reduced the amounts owed by NLG 875. This gain has
been disclosed as an extraordinary items as it meets the criteria as defined in
APB 30 "Reporting the Results of Operations--Extraordinary, Unusual and
Infrequently Occurring Events and Transactions, Gains and Losses from Unusual
and Infrequent Occurrences."

9. STOCKHOLDERS' DEFICIT

  The Company's Articles of Incorporation, as amended, authorise the Company to
issue 100,000 shares of NLG 10 par value common stock.

  During 1998, the stockholders contributed capital of NLG 606 in cash for
operating purposes.

10. STOCK COMPENSATION AGREEMENTS

  On April 25, 1998, the Company granted stock options to certain of its
stockholders. The stock option agreements with the stockholders consisted of
the right to purchase an aggregate of 5,625 newly issued shares of bART at an
exercise price of NLG 62 per share. The option was exercisable on April 25,
2000 (2 years from April 25, 1998) or in the event of the shares and/or
activities of bART being sold. The expiration date of the options is April 22,
2002.

  On April 28, 1998, the Company granted stock options to directors. The stock
option agreements with the directors consist of the right to purchase an
aggregate of 2,250 newly issued shares of bART at an exercise price of NLG 31
per share. The options are exercisable on or after April 25, 2000 or in the
event of the shares and/or activities of bART being sold. The options expire 5
years after the date of the grant.

  For disclosure purposes under SFAS No. 123, the fair value of each stock
option and granted is estimated on the date of the grant using the minimum
value method. The assumptions used in the minimum value method are as follows:

<TABLE>
          <S>                                      <C>
          Risk free interest rate.................   6%
          Expected life...........................   2 years
          Dividend yield..........................   0
</TABLE>

  The expected life was assumed to be 2 years as the options are exercisable
after 2 years from the grant date.

  Under the above method, the total value of the stock options granted to the
directors is NLG 7 which would be amortised over the vesting period defined as
two years. Had the Company determined compensation cost for these plans with
SFAS No. 123, the Company's pro forma results would not have differed
materially from the reported amounts.

  The value of the options granted to the stockholders is NLG 37 which would be
considered a stock dividend as these options would not be treated as
compensation expense.

                         NOTES TO FINANCIAL STATEMENTS

                (All amounts in thousand PTE except share data)

NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Business Operations

  Esoterica--Novas Tecnologias de Informacao, SA ("Company") was formed on
February 17, 1995 to operate as an Internet service provider (ISP) in the city
of Oporto. The Company now provides a full range of typical ISP services
throughout Portugal, and has its headoffice in Lisbon. On May 13, 1999, 100% of
the common stock was acquired by VIA NET.WORKS Europe Holding BV, a wholly-
owned subsidiary of VIA NET.WORKS, Inc.

 Basis of Presentation

  The Company is required to maintain its accounting records in accordance with
generally accepted accounting principles (GAAP) in the country of Portugal.
These financial statements have been prepared in accordance with GAAP in the
United States of America for the purposes of filing with the Securities and
Exchange Commission and do not represent the statutory financial statements of
the Company, which in are significantly different. The accompanying financial
statements include the results of the Company for the year ended December 31,
1998.

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires the Company to make estimates, judgements and
assumptions that affect the reported amounts of assets, liabilities, revenue
and expenses, together with amounts disclosed in the related notes to the
financial statements. Actual results could differ from the recorded estimates.

 Fair Value of Financial Instruments

  Carrying amounts of certain of the Company's financial instruments, including
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses and other liabilities approximate fair value due to their short
maturities. Based upon borrowing rates currently available to the Company for
loans with similar terms, the carrying value of debt and capital lease
obligations approximate their fair value.

 Cash and Cash Equivalents

  The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.

 Risks and Uncertainties

  The Company has a limited operating history and its operations are subject to
certain risks and uncertainties, including those associated with: the ability
to meet obligations, continuing losses, negative cash flow and fluctuations in
operating results; funding expansion; acquistions and strategic alliances,
including their integration; managing rapid growth and expansion; international
business activities; suppliers; financing arrangement terms that may restrict
operations; possible Year 2000 issues; regulatory issues; competition in the
Internet services industry; technology trends and evolving industry standards;
and delivering reliable service.

 Concentration of Credit Risk

  Financial instruments that potentially subject the Company to a concentration
of credit risk consist of cash, cash equivalents and accounts receivable. The
Company's accounts receivable are derived from revenue earned

                                     F-104

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

              (All amounts in thousand PTE except for share data)

from customers located in Portugal. The Company performs ongoing credit
evaluations of its customers' financial condition and, generally, requires no
collateral from its customers. The Company maintains an allowance for doubtful
accounts receivable based upon the expected collectibility of accounts
receivable.

 Inventory

  Inventory includes mainly CD ROMs and is stated at the lower of cost or
market, cost being determined using the first in first out (FIFO) method.

 Property and Equipment

  Property and equipment is recorded at cost less accumulated depreciation,
which is provided on the straight-line method over the estimated useful lives
of the assets, generally three to five years. Cost includes major expenditures
for improvements and replacements that extend useful lives or increase capacity
of the asset and interest costs associated with significant capital additions.
Expenditures for maintenance and repairs are expensed as incurred. Leasehold
improvements include costs associated with telecommunications equipment
installations and building improvements.

  The Company finances part of its data communications equipment and other
fixed assets under capital lease agreements. The assets and liabilities under
capital leases are recorded at the lesser of the present value of aggregate
future minimum lease payments, including estimated bargain purchase options, or
the fair value of the assets under lease. Assets under these capital leases are
depreciated over their estimated useful lives of three to five years, which are
generally longer than the terms of the leases.

  Costs for internal use software are expensed as incurred.

 Long-Lived Assets

  The Company periodically evaluates the carrying value of property and
equipment to be held and used when events and circumstances warrant such a
review. The carrying value of property and equipment is considered impaired
when the anticipated undiscounted cash flows from the asset is separately
identifiable and is less than its carrying value. In that event, a loss is
recognized based on the amount by which the carrying value exceeds the fair
value of the asset. Fair value is determined primarily using the anticipated
cash flows discounted at a rate commensurate with the risk involved. Losses on
assets to be disposed of are determined in a similar manner, except that fair
values are reduced for the cost to dispose.

 Income Taxes

  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109 (SFAS No. 109), "Accounting for Income
Taxes". SFAS No. 109 is an asset and liability approach that requires the
recognition of deferred tax assets and liabilities for the expected future tax
consequences attributable to differences between the carrying amounts of assets
and liabilities for financial reporting purposes and their respective tax
bases, and for operating loss and tax credit carryforwards. In estimating
future tax consequences, SFAS No. 109 generally considers all expected future
events other than the enactment of changes in tax laws or rates.

 Revenue Recognition

  Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance.

  Revenue from consulting services is recognized as the services are provided.
Revenue from hardware and third-party software sales is recognized upon
shipment of the respective products. Through December 31, 1998, such sales have
been immaterial. Other revenues include network installation, maintenance and
consulting services. These services are provided on a time-and-material basis
and revenue is recognized based upon time (at established rates) and other
direct costs as incurred.

 Costs of Revenues

  Costs of access revenues primarily consists of telecommunication expenses
inherent in the network infrastructure. Costs of access revenues also includes
fees paid for the network infrastructure, as well as other license fees paid to
third-party software vendors, product costs, and contractor fees for operation
and support services.

 Sources of Suppliers

  The Company relies on local telephone companies and other companies to
provide data communications. Although management feels alternative
telecommunication facilities could be found in a timely manner, any disruption
of these services could have an adverse effect on operating results.

 Recent Pronouncements

  In 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-1, Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use, and SOP 98-5, Reporting on the
Costs of Start-Up Activities, both of which are required to be adopted for
fiscal years beginning after December 15, 1998. SOP 98-1 provides guidance on
accounting for the costs of computer software developed or obtained for
internal use, determining whether computer software is for internal use, and
when costs incurred for internal-use computer software are and are not
capitalized. SOP 98-5 requires costs of start-up activities and organization
costs to be expensed as incurred. The early adoption of SOP 98-1 and SOP 98-5
did not have a material effect on the Company's financial statements.

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities (SFAS No. 133").
SFAS No. 133 establishes a new model for accounting for derivatives and hedging
activities and supersedes and amends a number of existing standards. SFAS No.
133 is effective for fiscal years beginning after June 15, 1999, Upon initial
application, all derivatives are required to be recognized in the statement of
financial position as either assets or liabilities and measured at fair value.
In addition, all hedging relationships must be reassessed and documented
pursuant to the provisions of SFAS No. 133. Subsequent to the issuance of SFAS
No. 133, the Financial Accounting Standards Board issued SFAS No. 137,
"Accounting for Derivative Instruments and Hedging Activities--Deferral of the
Effective Date of FASB Statement No. 133" ("SFAS No. 137"), which defers the
effective date of SFAS No. 133 to periods beginning after June 15, 2000. The
Company has not committed or expects to commit to any derivative instrument
transactions, and thus does not anticipate that this pronouncement will have a
significant effect on its results.

its shareholders.

 Line of credit

a line of credit with Barclays Bank. The line of credit provides for borrowings
of up to PTE 50,000. This line of credit does not expire and charges interest
at a rate of Lisbor (3 months) + 2.5% per annum. The line of credit is
guaranteed by the Company and its shareholders.

  ii) At December 31, 1998, the Company had PTE 10,000 outstanding and due

NOTE 4: COMMITMENTS

 Leases

2001. At December 31, 1998, the Company had PTE 27,975 outstanding and due
under an equipment lease financing line with Mello Leasing (Mello Locacao e
Renault Gest), with annual installments due of approximately PTE 10,000. The

The Company recognizes rent expense on a straight-line basis over the lease
period, and has accrued for rent expense incurred but not paid.

NOTE 5: INCOME TAXES

because it is currently more likely than not that such benefits will not be
realized. At December 31, 1998, the Company has potential net operating loss
carryforwards of approximately PTE 255,000, which may be used to offset future
taxable income. These carryforwards expire after 6 years from the date they are
reported in the fiscal tax return.

  Following the Company's acquisition on May 13, 1999, all bank borrowings have
been repaid and replaced with advances from VIA NET.WORKS, Inc. in the amount
of approximately PTE102,000.

To the Board of Directors and
Stockholders of Worldwide Web Services Limited

In our opinion, the accompanying balance sheet and the related statements of
operations, changes in stockholders' deficit, and of cash flows expressed in
British Pounds present fairly, in all material respects, the financial position
of Worldwide Web Services Limited as of May 27, 1999, and the results of its
operations and its cash flows for the period from July 1, 1998 to May 27, 1999,
in conformity with accounting principles generally accepted in the United
States of America. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audit. We conducted our audit of these
statements in accordance with generally accepted auditing standards in the
United Kingdom which are substantially similar to generally accepted auditing
standards in the United States of America which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for the opinion expressed above.

NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Business Operations

  Worldwide Web Services Limited ("the Company") was formed on May 24, 1996 to

On May 27, 1999, 100% of the common stock was acquired by VIA NET.WORKS, Inc.
Worldwide Web Services Limited was acquired for total consideration
of (Pounds)4,550.

 Basis of Presentation

  The Company maintains its accounting records in accordance with generally
accepted accounting principles (GAAP) in the United Kingdom. These financial
statements have been prepared in accordance with GAAP in the United States for

represent the statutory financial statements of the Company. The accompanying
financial statements include the results of the Company for the period from
July 1, 1998 to May 27, 1999 (the date that the Company was acquired by VIA

the related notes to the financial statements. Actual results could differ from
the recorded estimates.

 Fair Value of Financial Instruments

  The Company's financial instruments include cash and cash equivalents,
accounts receivable, accounts payable, accrued liabilities and other current
liabilities. The carrying amounts of financial instruments approximate fair
value due to their short-term maturities.

 Cash and Cash Equivalents

  The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.

 Concentration of Credit Risk

  Financial instruments that potentially subject the Company to a concentration
of credit risk consist of cash, cash equivalents and accounts receivable. The
Company's accounts receivable are derived from revenue earned from customers
located in United Kingdom. The Company performs ongoing credit evaluations of
its customers' financial condition and, generally, requires no collateral from
its customers. The Company maintains an allowance for doubtful accounts
receivable based upon the expected collectibility of accounts receivable.

 Inventory

  Inventory consists primarily of work-in-progress regarding web site authoring
and is stated at cost.

       (All amounts in thousands of GBP, except share and per share data)


 Property and Equipment

  Property and equipment is recorded at cost less accumulated depreciation,
which is provided on the straight-line method over the estimated useful lives
of the assets as follows:

<TABLE>
          <S>                                        <C>
          Machinery and Equipment................... 4 years
          Vehicles.................................. 4 years
          Furniture and Fixtures.................... 4 years
</TABLE>

  Cost includes major expenditures for improvements and replacements which
extend useful lives or increase capacity of the asset and interest costs
associated with significant capital additions. Expenditures for maintenance and
repairs are expensed as incurred.

  Costs for internal use software are expensed as incurred.

 Long-Lived Assets

  The Company periodically evaluates the carrying value of property and
equipment to be held and used when events and circumstances warrant such a
review. The carrying value of property and equipment is considered impaired
when the anticipated undiscounted cash flows from the asset is separately
identifiable and is less than its carrying value. In that event, a loss is
recognized based on the amount by which the carrying value exceeds the fair
value of the asset. Fair value is determined primarily using the anticipated
cash flows discounted at a rate commensurate with the risk involved. Losses on
assets to be disposed of are determined in a similar manner, except that fair
values are reduced for the cost to dispose.

 Income Taxes

  The Company recognizes deferred tax liabilities and assets for the expected
future tax consequences of events that have been included in the financial
statements or tax returns in accordance with SFAS No. 109, "Accounting for
Income Taxes" ("SFAS 109"). Deferred tax liabilities and assets are determined
on the basis of the difference between the income tax basis of assets and
liabilities and their respective financial reporting amounts at tax rates in
effect for the periods in which the differences are expected to reverse. The
Company provides a valuation allowance for deferred tax assets when it is more
likely than not, based on available evidence, that some portion or all of the
deferred tax assets will not be realized.

 Revenue Recognition

  Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance, and
releases to revenue ratably over subscription term ranging from three to twelve
months.

  Revenue from consulting services is recognized as the services are provided.
Revenue from hardware and third party software sales is recognized upon
shipment of the respective products. Through May 27, 1999, such sales have been
immaterial. Other revenues include network installation, maintenance and
consulting services. These services are provided on a time-and-material basis
and revenue is recognized based upon time (at established rates) and other
direct costs as incurred.

 Costs of Revenues

  Costs of access revenues primarily consist of telecommunication expenses
inherent in the network infrastructure, license fees for Web browser software
based on a per-user charge, other license fees paid to third-party software
vendors, product costs, and contractor fees for operation and support services.

 Advertising Costs

  Advertising costs are charged to operations when incurred. There were no
advertising expenses incurred for the period from July 1, 1998 to May 27, 1999.

 Sources of Suppliers

  The Company relies on local telephone companies and other companies to
provide data communications. Although management feels alternative
telecommunication facilities could be found in a timely manner, any disruption
of these services could have an adverse effect on operating results.

 Recent Pronouncements

  In March 1998, the American Institute of Certified Public Accounts ("AICPA")
issued Statement of Position ("SOP") No. 98-1, "Software for Internal Use,"
which provides guidance on accounting for the cost of computer software
developed or obtained for internal use. SOP No. 98-1 is effective for financial
statements for fiscal years beginning after December 15, 1998. The early
adoption of SOP 98-1 did not have a material effect on the Company's financial
statements.

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 establishes a new model for accounting for derivatives and
hedging activities and supersedes and amends a number of existing standards.
SFAS No. 133 is effective for fiscal years beginning after June 15, 1999, but
earlier application is permitted as of the beginning of any fiscal quarter
subsequent to June 15, 1998. Upon initial application, all derivatives are
required to be recognized in the statement of financial position as either
assets or liabilities and measured at fair value. In addition, all hedging
relationships must be reassessed and documented pursuant to the provisions of
SFAS No. 133. Subsequent to the issuance of SFAS No. 133, the Financial
Accounting Standards Board issued SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133" ("SFAS No. 137"), which defers the effective date of SFAS
No. 133 to periods beginning after June 15, 2000. The Company has not committed
or expects to commit to any derivative instrument transactions, and thus does
not anticipate that this pronouncement will have a significant effect on its
results.

NOTE 3: COMMITMENTS

 Operating Leases

  The Company leases office space under noncancelable operating leases that
expire in 2007. Rent expense for the period from July 1, 1998 to May 27, 1999
was (Pounds)83. The terms of the facility lease provide for rental payments on
a graduated scale. The Company recognizes rent expense as incurred over the
lease period. Future minimum lease payments under noncancelable operating
leases, including lease commitments entered into subsequent to May 27, 1999
under noncancelable operating leases are as follows:

</TABLE>

  In March of 2002, the Company's operating leases will be reviewed by the
landlord and a new monthly rental expense will be assessed at that time through
March of 2007.

NOTE 4: STOCKHOLDERS' DEFICIT

  The Company's Memorandum and Articles of Association, as amended, authorize
the Company to issue 100,000 shares of (Pounds)1.00 par value common stock.
Holders of the Company's common stock are entitled to one vote per share. The
Board of Directors is elected by a majority vote of the shares of common stock
voting thereon and any action to be taken by the stockholders requires a
majority vote of the shares of common stock voting thereon.

  In May 1999, 5,556 common stock shares were issued to two key employees at a
price below the fair market value at the date of the issuance. The exercise
price paid by the employees was (Pounds)1 per share. Fair market value at the
date of issuance was (Pounds)81.89 per share. The Company recognized
(Pounds)449 in compensation expense and (Pounds)235 in related taxes, during
the period from July 1, 1998 to May 27, 1999 in connection with the issuance of
common stock. Compensation expense is equal to the difference between what the
employees paid for the shares and the amount that VIA NET.WORKS, Inc.
subsequently paid to acquire the shares. Had the Company determined
compensation cost for these shares in accordance with SFAS No. 123, the
Company's pro forma results would not have differed materially from the
reported amount.

NOTE 5: INCOME TAXES

  No provision for income taxes was recorded from the period July 1, 1998
through May 27, 1999 as the Company incurred net operating losses during the
period. The components of the net deferred tax asset as of May 27, 1999 is as
follows:

       (All amounts in thousands of GBP, except share and per share data)


  Management has evaluated the positive and negative evidence impacting the
realizeability on the deferred tax asset. Management has considered the history
of losses and has concluded that as of May 27, 1999, the deferred tax asset
more likely than not will not be realized. Therefore, management has recorded a
full valuation allowance against the deferred tax asset. Net operating losses
for tax purposes can be carried forward indefinitely to offset future taxable
income from Internet services.

NOTE 6: RELATED PARTY TRANSACTIONS

  During the period presented, the Company purchased goods and services for a
total of (Pounds)6 from a related party, a relative of a director. At May 27,
1999 the Company owed a total of (Pounds)50 to two related parties, split
equally. The related parties were a director and a company in which a director
has an interest. Neither loan was interest bearing and both were repaid
subsequent to May 27, 1999 shortly after the end of the period.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of Netlink Internet Services Limited

In our opinion, the accompanying balance sheet and the related statements of
operations, changes in stockholders' deficit, and of cash flows expressed in
British Pounds present fairly, in all material respects, the financial position
of Netlink Internet Services Limited as of December 31, 1998, and the results
of its operations and its cash flows for the year then ended, in conformity
with accounting principles generally accepted in the United States of America.
These financial statements are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements based
on our audit. We conducted our audit of these statements in accordance with
generally accepted auditing standards in the United Kingdom which are
substantially similar to generally accepted auditing standards in the United
States of America which 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, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audit provides a reasonable basis for the opinion expressed above.

NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Business Operations

  Netlink Internet Services, Ltd. ("the Company") was formed on September 7,
1995 to operate as an Internet service provider (ISP) in the city of London,
England. On July 9, 1999, 100% of the common stock was acquired by VIA
NET.WORKS, Inc., for total consideration of (Pounds)7,500.

 Basis of Presentation

  The Company maintains its accounting records in accordance with generally
accepted accounting principles (GAAP) in the United Kingdom. These financial
statements have been prepared in accordance with GAAP in the United States for
purposes of filing with the Securities and Exchange Commission and do not
represent the statutory financial statements of the Company. The accompanying
financial statements include the results of the Company for the year ended
December 31, 1998 and for the unaudited six month periods ended June 30, 1998
and 1999.

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles in the United States requires the Company to make
estimates, judgments and assumptions that affect the reported amounts of
assets, liabilities, revenue and expenses, together with amounts disclosed in
the related notes to the financial statements. Actual results could differ from
the recorded estimates.

 Fair Value of Financial Instruments

  Carrying amounts of certain of the Company's financial instruments, including
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses and other liabilities approximate fair value due to their short
maturities. Based upon borrowing rates currently available to the Company for
loans with similar terms, the carrying value of long-term debt and capital
lease obligations approximate fair value.

 Cash and Cash Equivalents

  The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.

 Property and Equipment

  Property and equipment is recorded at cost less accumulated depreciation,
which is provided on the straight-line method over the estimated useful lives
of the assets, generally three years. Cost includes major expenditures for
improvements and replacements which extend useful lives or increase capacity of
the asset and interest costs associated with significant capital additions.
Expenditures for maintenance and repairs are expensed as incurred.

  Costs for internal use software are expensed as incurred.

 Long-Lived Assets

  The Company periodically evaluates the carrying value of property and
equipment to be held and used when events and circumstances warrant such a
review. The carrying value of property and equipment is

                                     F-123
<PAGE>

                       NETLINK INTERNET SERVICES LIMITED

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

        (All amounts in thousands GBP, except share and per share data)
considered impaired when the anticipated undiscounted cash flows from the asset
is separately identifiable and is less than its carrying value. In that event,
a loss is recognized based on the amount by which the carrying value exceeds
the fair value of the asset. Fair value is determined primarily using the
anticipated cash flows discounted at a rate commensurate with the risk
involved. Losses on assets to be disposed of are determined in a similar
manner, except that fair values are reduced for the cost to dispose.

 Income Taxes

  The Company recognizes deferred tax liabilities and assets for the expected
future tax consequences of events that have been included in the financial
statements or tax returns in accordance with SFAS No. 109, "Accounting for
Income Taxes" ("SFAS 109"). Deferred tax liabilities and assets are determined
on the basis of the difference between the income tax basis of assets and
liabilities and their respective financial reporting amounts at tax rates in
effect for the periods in which the differences are expected to reverse. The
Company provides a valuation allowance for deferred tax assets when it is more
likely than not, based on available evidence, that some portion or all of the
deferred tax assets will not be realized.

 Revenue Recognition

  Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance and
releases to revenue ratably over subscription term ranging from three to twelve
months.

 Concentration of Credit Risk

  Financial instruments that potentially subject the Company to a concentration
of credit risk consist of cash, cash equivalents and accounts receivable. The
Company's accounts receivable are derived from revenue earned from customers
located in United Kingdom and from other European countries. The Company
performs ongoing credit evaluations of its customers' financial condition and,
generally, requires no collateral from its customers. The Company maintains an
allowance for doubtful accounts receivable based upon the expected
collectibility of accounts receivable.

 Costs of Revenues

  Costs of access revenues primarily consist of telecommunication expenses
inherent in the network infrastructure. Costs of access revenues also includes
fees paid for lease of the company's network infrastructure, as well as license
fees for Web browser software based on a per-user charge, other license fees
paid to third-party software vendors, product costs, and contractor fees for
operation and support services.

 Advertising Costs

  Advertising costs are charged to operations when incurred. Advertising
expense for the year ended December 31, 1998, was (Pounds)126.

 Sources of Suppliers

  The Company relies on local telephone companies and other companies to
provide data communications. Although management feels alternative
telecommunication facilities could be found in a timely manner, any disruption
of these services could have an adverse effect on operating results.

 Research and Development

  Costs incurred in research and development are charged to operations when
incurred. Research and development expense for the year ended December 31, 1998
and the unaudited periods ended June 30, 1998 and 1999 were (Pounds)32,
(Pounds)Nil (unaudited) and (Pounds)Nil (unaudited) respectively.

 Recent Pronouncements

  In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") No. 98-1, "Software for Internal
Use," which provides guidance on accounting for the cost of computer software
developed or obtained for internal use. SOP No. 98-1 is effective for financial
statements for fiscal years beginning after December 15, 1998. The early
adoption of SOP 98-1 did not have a material effect on the Company's financial
statements.

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 establishes a new model for accounting for derivatives and
hedging activities and supersedes and amends a number of existing standards.
SFAS No. 133 is effective for fiscal years beginning after June 15, 1999, but
earlier application is permitted as of the beginning of any fiscal quarter
subsequent to June 15, 1998. Upon initial application, all derivatives are
required to be recognized in the statement of financial position as either
assets or liabilities and measured at fair value. In addition, all hedging
relationships must be reassessed and documented pursuant to the provisions of
SFAS No. 133. Subsequent to the issuance of SFAS No. 133, the Financial
Accounting Standards Board issued SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133" ("SFAS No. 137"), which defers the effective date of SFAS
No. 133 to periods beginning after June 15, 2000. The Company has not committed
or expects to commit to any derivative instrument transactions, and thus does
not anticipate that this pronouncement will have a significant effect on its
results.

 Unaudited Interim Financial Information

  The interim financial information for the six months ended June 30, 1998 and
1999 included herein is unaudited. However, the company believes that interim
financial information includes all adjustments, consisting of only normal
recurring adjustments, necessary for a fair presentation of the results of
interim periods. The results of operations for the six months ended June 30,
1999 are not necessarily indicative of the results to be expected for the year
ending December 31, 1999.

</TABLE>

  The Company has established a valuation allowance for net deferred tax assets
of its operations since realization of these benefits cannot be reasonably
assured. These net operating losses are available for carryforward indefinitely
and can be offset against future profits of the same trade. While the need for
the valuation allowance is subject to periodic review, if the allowance is
reduced, the tax benefits of the carryforwards will be recorded in future
operations as a reduction of the Company's income tax expense. No cash was paid
for income taxes in the year ended December 31, 1998.

NOTE 8: RELATED PARTY TRANSACTIONS

  Throughout the year ended December 31, 1998 and the unaudited six months
period ended June 30, 1999, a director of Netlink Internet Services Limited

1999 together with interest charged at a per annum rate of 6.6875%.

                       Report of Independent Accountants

To the Board of Directors and
Stockholders of DISBUMAD, SL

In our opinion, the accompanying balance sheet and the related statements of
operations, stockholders' deficit and cash flows present fairly, in all
material respects, the financial position of Disbumad, SL at December 31, 1998,
and the results of its operations and its cash flows for the year ended
December 31, 1998 in conformity with generally accepted accounting principles
in the United States. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audit. We conducted our audit of these
statements in accordance with generally accepted auditing standards in the
United States, which 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, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audit provides a reasonable basis for the opinion expressed above.

Yours faithfully,

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Business Operations

  DISBUMAD, SL (the "Company") was formed on October 27, 1994 to operate as an
online bookshop. During 1997, the company started its activities as an Internet
Services Provider (ISP) in Spain. On August 26, 1999 the Company was acquired
by VIA NET.WORKS, Inc.

 Basis of Presentation

  The Company maintains its accounting records in accordance with generally
accepted accounting principles (GAAP) in Spain. These financial statements have
been prepared in accordance with GAAP in the United States of America for
purposes of filing with the Securities and Exchange Commission and do not
represent the statutory financial statements of the Company. The accompanying
financial statements include the results of the Company for the year ended
December 31, 1998.

 Interim Financial Information

  Interim financial information for the six months ended June 30, 1998 and 1999
included herein is unaudited. However, the Company believes the interim
financial information includes all adjustments, consisting of only normal
recurring adjustments, necessary for a fair presentation of the results of
interim periods. The results of operations for the six months ended June 30,
1999 are not necessarily indicative of the results to be expected for the year
ending December 31, 1999.

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires the Company to make estimates, judgments and
assumptions that affect the reported amounts of assets, liabilities, revenue
and expenses, together with amounts disclosed in the related notes to the
financial statements. Actual results could differ from the recorded estimates.

 Fair Value of Financial Instruments

  Carrying amounts of certain of the Company's financial instruments, including
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses and other liabilities approximate fair value due to their short
maturities. Based upon borrowing rates currently available to the Company for
loans with similar terms, the carrying value of debt and capital lease
obligations approximate their fair value.

 Cash and Cash Equivalents

  The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.

 Concentration of Credit Risk

  Financial instruments that potentially subject the Company to a concentration
of credit risk consist of cash, cash equivalents and accounts receivable. The
Company performs ongoing credit evaluations of its customers' financial
condition and, generally, requires no collateral from its customers. The
Company maintains an allowance for doubtful accounts receivable based upon the
expected collectibility of accounts receivable. No significant concentration of
credit risk exists.

                 NOTES TO THE FINANCIAL STATEMENTS--(Continued)
    (Information for the six months ended June 30, 1999 and June 30, 1998 is
                                   unaudited)
   (All amounts expressed in thousands of pesetas--Pths except share amounts)


 Inventory

  Inventory consists of books and is stated at the lower of cost or market,
cost being determined by their purchase price.

 Tangible Fixed Assets

  Fixed assets are recorded at cost less accumulated depreciation, which is
provided on the straight-line method over the estimated useful lives of the
assets, generally four to ten years. Cost includes major expenditures for
improvements and replacements which extend the useful life or increase capacity
of the asset and interest cost associated with significant capital additions.
Expenditures for maintenance and repairs are expensed as incurred.

  Costs for internally generated internal use software are expensed as
incurred.

 Long-Lived Assets

  The Company periodically evaluates the carrying value of property and
equipment to be held and used when events and circumstances warrant such a
review. The carrying value of property and equipment is considered impaired
when the anticipated undiscounted cash flows from the asset is separately
identifiable and is less than its carrying value. In that event, a loss is
recognized based on the amount by which the carrying value exceeds the fair
value of the asset. Fair value is determined primarily using the anticipated
cash flows discounted at a rate commensurate with the risk involved. Losses on
assets to be disposed of are determined in a similar manner, except that fair
values are reduced for the cost to dispose.

 Advertising Expense

  Costs related to advertising and promotion of services is charged to sales
and marketing expense as incurred.

  The Company contracted for an advertising campaign on November 15, 1998 for a
twelve-month period for a total amount of Pths 4,644. As of December 31, 1998
the balance of Pths 4,562 related to this contract is included as a prepayment
and will be expensed as the services are rendered.

 Income Taxes

  The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes". SFAS No. 109 is an asset and liability approach
that requires the recognition of deferred tax assets and liabilities for the
expected future tax consequences attributable to differences between the
carrying amounts of assets and liabilities for financial reporting purposes and
their respective tax bases, and for operating loss and tax credit
carryforwards. In estimating future tax consequences, SFAS No. 109 generally
considers all expected future events other than the enactment of changes in tax
laws or rates.

 Revenue Recognition

  Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and collected in advance.

  Revenue from consulting services is recognized as the services are provided.
Revenue from books sales is recognized upon shipment of the product.

                 NOTES TO THE FINANCIAL STATEMENTS--(Continued)
    (Information for the six months ended June 30, 1999 and June 30, 1998 is
                                   unaudited)

 Cost of Revenues

  Costs of access revenues consists of telecommunication expenses inherent in
the network infrastructure.

  Cost of books sold are recorded at their carrying value.

 Sources of Suppliers

  The Company relies on local telephone companies and other companies to
provide data communications. Although Management believes that alternative
telecommunication facilities could be found in a timely manner, however any
disruption of these services could have an adverse effect on operating results.

 Comprehensive Income

  The Company has adopted the accounting treatment prescribed by SFAS No. 130,
Comprehensive Income. FAS No. 130 establishes standards for reporting and
displaying comprehensive income and its components. The adoption of this
statement has not impacted the Company's financial statements as a result of
the Company not having any comprehensive income other than net loss during the
periods presented.

 Segment Reporting

  The Company adopted SFAS No. 131, Disclosures about Segments of an Enterprise
and Related Information, during 1998. SFAS No. 131 replaces the "industry
segment" approach with the "management" approach. The management approach
designates the internal organization that is used by management for allocating
resources and assessing performance as the source of the Company's reportable
segments. SFAS No. 131 also requires disclosures about products and services,
geographic areas, and major customers. The adoption of SFAS No. 131 did not
effect the Company's results of operations or financial position. The Company
operates in two segments, bookshop and ISP. All operations are made within
Spain.

 Recent Pronouncements

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 establishes a new model for accounting for derivatives and
hedging activities and supersedes and amends a number of existing standards.
SFAS No. 133 is effective for fiscal years beginning after June 15, 1999, but
earlier application is permitted as of the beginning of any fiscal quarter
subsequent to June 15, 1998. Upon initial application, all derivatives are
required to be recognized in the statement of financial position as either
assets or liabilities and measured at fair value. In addition, all hedging
relationships must be reassessed and documented pursuant to the provisions of
SFAS No. 133. Subsequent to the issuance of SFAS No. 133, the Financial
Accounting Standards Board issued SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133" ("SFAS No. 137"), which defers the effective date of SFAS
No. 133 to periods beginning after June 15, 2000. The Company has not committed
or expects to commit to any derivative instrument transactions, and thus does
not anticipate that this pronouncement will have a significant effect on its
results.

  In 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-1, Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use, which is required to be
adopted for fiscal years beginning after December 15, 1998. SOP 98-1 provides
guidance on accounting for

  The Company has established a valuation allowance for deferred tax assets of
its operations since realization of these benefits cannot be reasonably
assured. The related operating loss carryforwards expire at various future
dates through 2008. While the need for the valuation allowance is subject to
periodic review, if the allowance is reduced, the tax benefit of the
carryforwards will be recorded in future operations as a reduction of the
Company's income tax expense. No cash was paid for income taxes in the periods
reported.

  The Company's net tax loss carry-forwards as of December 31, 1998 expire as
follows:

  An additional loss carry-forward of Pths 9,432 to expire in 2009 results from
the estimated tax loss for the period ended June 30, 1999, which will be
included in the annual income tax return for 1999.

  Temporary differences will be accounted for in local statutory accounting
records at 1999 year-end, therefore generating additional tax loss
carryforwards that will expire in year 2009.

10. SUBSEQUENT EVENTS

 Audited

  VIA NET.WORKS, Inc. acquired 85.23% of Disbumad, SL common stock as of August
26, 1999. Subject to the purchase agreement, Disbumad, SL will increase its
equity by Pths 303,000 in three tranches.

  The first increase has been completed in August, 1999 for Pths 101,000. This
increase was formalized with a common stock increase of Pths 5,390 and a
premium of Pths 95,610. The following increases are expected for the same
amount in February, 2000 and August, 2000.

  Prior to the acquisition by VIA NET.WORKS, the Company sold the assets
relating to the bookshop activity to its previous stockholders. The main assets
sold were the office building, some equipment, furniture and inventory for a
total amount of Pths 85,076. This operation had a positive impact of Pths 71 in
the Profit and Loss account in August, 1999.

 Unaudited

  During November 1999, the Board of Directors will submit to the approval of
the shareholders, the merger of Disbumad, SL with its Holding Company, Via Net
Works Spain Holdings, SL. Management expects that this transaction will not
have any impact in the activities of the Company.

                          Independent Auditors' Report

The Board of Directors and Stockholders
Infoacces, S. A. de C. V. and Subsidiary:

We have audited the consolidated balance sheets of Infoacces, S. A. de C. V.
and Subsidiary as of December 31, 1997 and 1998, and the related consolidated
statements of operations, changes in stockholders' equity and changes in
financial position for each of the years in the two-year period ended December
31, 1998. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards in Mexico which are substantially the same as those followed 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, and are prepared in accordance with generally accepted
accounting principles. An audit consists of 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.

As discussed in note 1a., the consolidated financial statements have been
restated in order to present all periods of the consolidated financial
statements in constant pesos as of the most recent balance sheet date as
required by Bulletin B-10 "Recognition of the Effects of Inflation on the
Financial Information" issued by the Mexican Institute of Public Accountants.
The above mentioned consolidated financial statements have been restated from
amounts previously reported to reflect the purchasing power of the Mexican peso
as of September 30, 1999.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Infoacces, S. A. de
C. V. and Subsidiary at December 31, 1997 and 1998, and the results of their
operations, the changes in their stockholders' equity and the changes in their
financial position for each of the years in the two-year period ended December
31, 1998, in accordance with generally accepted accounting principles in
Mexico.

Generally accepted accounting principles in Mexico vary in certain significant
respects from generally accepted accounting principles in the United States.
Application of generally accepted accounting principles in the United States
would have affected results of operations for each of the years in the two-year
period ended December 31, 1998, and stockholders' equity as of December 31,
1997 and 1998 to the extent summarized in note 15 to the consolidated financial
statements.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                           December 31, 1997 and 1998

               (Constant Mexican pesos as of September 30, 1999)

(1) Operations and summary of significant accounting policies:

  Infoacces, S. A. de C. V. (Infoaccess or "the Company") was organized in
October 1993. The Company is an internet data communications carrier and
provides a wireline internet connectivity and internet services through its
network capability. The Company also provides internet connectivity in largest
metropolitan areas in Mexico and renders professional, technical and designed
web services and its derivatives.

  The Company's operations are subject to certain risks and uncertainties
including those associated with: acquisition and utilization of bandwidth;
dependence on key personnel; dependence on suppliers; possible year 2000
issues; regulatory issues; competition in the internet services industry;
technology trends; economy changes and evolving industry standards; and,
delivering reliable service.

  On November 30, 1996, Infoacces merged with Infoserv, S. A. de C. V.
(affiliate), Alta Corporativo, S. A. de C. V. (affiliate) and Infoserve
Information Services, S. A. de C. V. (holding company) becoming Infoacces the
sucessor Company.

  Accounting policies and practices used by the Company, in the preparation of
the accompanying consolidated financial statements are as follows:

  a. Financial statement presentation--The accompanying financial statements
     have been prepared in accordance with generally accepted accounting
     principles in Mexico, which include the recognition of the effects of
     inflation on the financial information, and are expressed in Mexican
     pesos of constant purchasing power as of the date of the most recent
     balance sheet presented. The inflation is computed based on the National
     Consumer Price Index (NCPI) provided by the Banco de Mexico (Central
     Bank). The related factors derived therefrom have been used to express
     the financial statements in constant Mexican pesos as of September 30,
     1999. The corresponding notes have been revised from the notes
     originally prepared under Mexican GAAP in order to comply with the
     disclosure requirements of Accounting Principles Generally Accepted in
     the United States (U.S. GAAP) and with the regulations of the U.S.
     Securities and Exchange Commission (SEC).

  b. Unaudited interim financial statements--In the opinion of the
     management, all adjustments (consisting of only normal recurring
     accruals) considered necessary for a fair presentation have been
     included. Operating results for the nine months ended September 30, 1999
     are not necessarily indicative of results that may be expected for the
     year ending December 31, 1999.

  c. Principles of consolidation--The consolidated financial statements
     include those of Infoacces and its subsidiary CSI, S. A. de C. V. (CSI)
     in which the Company holds a majority interest and has control.

    All significant intercompany balances and transactions have been
    eliminated in consolidation.

  d. Revenue recognition--Revenue and related direct costs from customer
     contracts are recognized ratably over the terms of the contract, which
     are generally three months to one year. Cash received in advance of
     revenues earned is recorded as deferred revenue. The Company also
     provides connectivity software products and design services. Revenue
     from the sale of software and services is recognized when software and
     designed web are delivered and accepted by the customer.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

               (Constant Mexican pesos as of September 30, 1999)


  e. Advertising expenses--The Company expenses all advertising costs in the
     period incurred. Advertising expense was Mp$3,796,309, Mp$5,972,671 and
     Mp$4,973,000 for the years ended December 31, 1997 and 1998, and for
     nine months ended September 30, 1999 (unaudited), respectively.

  f. Cash and cash equivalents--Cash and cash equivalents include all highly
     liquid investments purchased with original maturities of three months or
     less. Cash equivalents consist of approximately Mp$3,428 and Mp$5,203 at
     December 31, 1997 and 1998, respectively. Gains or losses resulting from
     changes in market value and the effects of inflation are included in the
     accompanying statements of operations as part of comprehensive financing
     income or costs.

  g. Inventories and cost of sales--Inventory consists primarily of wireless
     modems and accessories and is stated at the lower of cost or market.
     Cost is determined using identified cost. The inventory of the Company
     is subject to rapid technological changes which could have an adverse
     impact on its realization in future periods.

  h. Fair value of financial instruments--The carrying amounts of the
     Company's financial instruments, which include cash equivalents,
     accounts receivable, obligations under capital leases accounts payable
     and accrued expenses approximate their fair values. The carrying amounts
     of long term debt and obligations approximate fair value based upon the
     Company's borrowing activities and assessment of current prices offered
     for similar loans.

  i. Concentration of credit risk--Financial instruments that potentially
     subject the Company to a concentration of credit risk consist of
     accounts receivable. The Company extends credit to its customers on a
     unsecured basis in the normal course of business. As of December 31,
     1998, the Company had concentration of trade receivable denominated in
     foreign currency from two customers of approximately Mp$2,380,000. The
     Company maintains reserves for potential credit losses.

  j. Furniture and equipment--Furniture and equipment are updated using
     factors derived from the NCPI.

    Depreciation is computed under the straight-line method, according to
    the estimated useful lives of the assets, at the annual rates mentioned
    in note 6. The costs of leasehold improvements are capitalized and
    amortized using the straight-line method over the lesser of the lease
    term or the estimated useful life of the asset.

    Leasehold improvements include costs associated with telecommunications
    equipment installation and building improvements. No interest was
    capitalized in 1997 and 1998.

    The Company finances part of its data communication equipment and other
    fixed assets under capital lease agreements. The assets and liabilities
    under capital leases are recorded at the lesser of the present value of
    aggregate future minimum lease payments, or the fair value of the
    assets under lease. Assets under these capital leases are depreciated
    over their estimated useful life three to ten years.

    The carrying value of property, plant and equipment is assessed
    annually and/or when factors indicating possible impairment are
    present. If an impairment is present, the assets are reported at the
    lower of carrying value or fair value.

  k. Other assets--Other assets principally comprise capitalized pre-
     operating expenses and capitalized costs of "Contenidos" project
     (virtual information newspaper developed and customized over the
     internet-web page) updated through NCPI factors. These assets are
     amortized at annual rates ratably over the estimated life of the
     project.

    At December 31, 1998 "Contenidos" project had not been amortized
    because it was in the development stage. The Company has estimated that
    this project will be launched during 1999. (See notes 7 and 14).

  l. Long-lived assets--The Company's policy is to review long lived assets
     for impairment whenever events or changes in circumstances indicate that
     the carrying amounts may not be recoverable.

               (Constant Mexican pesos as of September 30, 1999)

     Impairment is measured by comparing the carrying value of the asset to
     the estimated undiscounted future cash flows expected to result from use
     of the assets and their eventual disposition. The measurement of the
     impairment loss to be recognized is based upon the difference between
     the fair value and the carrying amounts of the assets. The Company
     determined that as of December 31, 1997 and 1998, there had been no
     impairment in the carrying value of long-lived assets.

  m. Income tax (IT) and employees' statutory profit sharing (ESPS)--IT and
     ESPS expenses include the amounts payable and, in addition, recognize
     the effects on IT and ESPS of significant timing differences between
     taxable and book income, on which it may reasonably be estimated that
     over a defined period a tax benefit or liability will arise; other
     effects are recognized when realized.

  n. Seniority premiums and severance payments--Seniority premiums to which
     employees are entitled upon retirement after 15 years or more of
     service, in accordance with the Federal Labor Law, have not been
     recognized as cost of the years in which services are rendered, because
     the accrued liability, based on Company's estimates, is not material.

    Any other payments to which employees may be entitled in the event of
    dismissal, disability or death are charged to operations for the year in
    which paid.

  o. Foreign currency transactions and exchange differences--Foreign currency
     transactions are recorded at the rates of exchange prevailing on the
     date of execution or settlement. Foreign currency assets and liabilities
     are translated at the exchange rates in force at the balance sheet date.
     Exchange differences arising from assets or liabilities denominated in
     foreign currencies are charged to operations for the year, and included
     under comprehensive financing income or cost.

  p. Monetary gain (loss)--Determined by multiplying the difference between
     monetary assets and liabilities, at the beginning of each month, by
     inflation through year-end. The aggregate of these results represents
     the monetary gain or loss for the year, arising from inflation.

  q. Updating of common stock, additional paid-in capital and accumulated
     deficit--Determined by multiplying stockholders' contributions and
     accumulated deficit by factors derived from the NCPI, which measure
     accumulated inflation from the dates contributions were made and
     earnings (losses) arose through year-end. The resulting amounts
     represent the constant values of stockholders' equity.

  r. Use of estimates--The preparation of consolidated financial statements
     in conformity with generally accepted accounting principles requires
     management to make estimates and assumptions that affect the reported
     amounts of assets and liabilities and the disclosure of contingent
     assets and liabilities at the date of the financial statements, and the
     reported amounts of revenues and expenses during the reporting period.
     Actual results could differ from those estimates.

(2) Acquisition and sale of CSI:

  On October 9, 1997, the Company acquired 95% interest of CSI, S. A. de C. V.
(CSI). The acquisition was accounted using the purchase method of accounting
and, accordingly, the net assets and results of operations of the acquired
company has been included in the Company's consolidated financial statements
since the acquisition date. The purchase price of the acquisition was
allocated to assets acquired and liabilities assumed, based on their
respective fair values at the acquisition date.

  CSI develops and designs web pages and other web applications.

               (Constant Mexican pesos as of September 30, 1999)


  In connection with this acquisition, the Company paid approximately
Mp$1,299,000. The amount paid exceeded its fair market value of the net assets
of Mp$154,411, which were recorded in the statements of operations.

  In July 1, 1999, the Company sold its 95% interest of CSI, for approximately
Mp$1,410,000 (unaudited). In connection with the transaction, the Company no
longer consolidates the assets and liabilities of CSI. The net assets of CSI
consolidated into the amounts of the Company was approximately Mp$674,000 as of
June 30, 1999. As a result of this transaction, the Company recognized a gain
of approximately Mp$1,026,000 (unaudited) in the nine months ended September
30, 1999 (see note 14).

  The following represents the results of operations of the Company for the
years ended December 31, 1997 and 1998 as if the acquisition was consummated on

 b. Changes in stockholders' equity:

  --At the Extraordinary Stockholders' Meeting held on January 28, 1997, it
   was agreed to increase the fixed portion of common stock, issuing
   1,824,998 Series "A" shares, with a par value of one Mexican peso each,
   equivalent to Mp$2,674,809 (Mp$1,824,998 historical). These shares were
   paid through capitalization of contributions for future capital stock
   increases, previously paid in cash.

   It was also agreed to change the minimum fixed portion of common stock,
   so that it be represented by 5,750,000 Series "A" shares, not subject to
   withdrawal.

  --At the Extraordinary Stockholders' Meeting held on May 14, 1997, final
    approval was granted for the merger of Infoserv, S. A. de C. V., Alta
    Corporativo, S. A. de C. V. (affiliated companies) and Infoserve
    Information Services, S. A. de C. V. (parent company) into Infoacces, S.
    A. de C. V. and Subsidiary, effective November 30, 1996. Infoacces, S. A

   As a result of the above, the variable portion of the capital stock was
   increased issuing 256,002 Series "B" shares, with a par value of one peso
   each, equivalent to Mp$358,216 ($256,002 historical), which had been
   previously recognized as additional paid-in capital. The new shares are
   represented by registered provisional certificates, to be delivered to
   the stockholders upon signature of the protocolization document of this
   Meeting's minutes. Such provisional certificates must be exchanged for
   final certificates within one year from the date of the meeting.

  --At the Stockholders' Meeting held on October 15, 1997, it was agreed to
    increase the variable portion of common stock, issuing of 350,000 Series
    "B" shares, with a par value of one peso each, equivalent to Mp$466,178
    (Mp$350,000 historical); it was also agreed that these shares were paid
    with a premium of Mp$972,412 (Mp$730,000 historical), through
    capitalization of contributions for future capital stock increases,
    previously paid in cash.

  --At the Extraordinary Stockholders' Meeting held on August 11, 1998, it
    was agreed to transfer 2,250,000 shares of the variable portion to the
    fixed minimum common stock. After this change, the minimum fixed portion
    of common stock was represented by 8,000,000 common, registered Series
    "A" shares with a par value of one Mexican peso each.

  --At the Extraordinary Stockholders' Meeting held on November 26, 1998 it
    was agreed to increase the variable portion of common stock by
    Mp$8,849,371 (Mp$8,000,000 historical), issuing 800,000 Series "B"
    shares, with no par value. Mp$4,180,134 (Mp$3,737,025 historical) was
    paid in cash, while Mp$4,669,237 is still unpaid. It was also agreed to
    eliminate the par value of the shares.

  --At the Ordinary Stockholders' Meeting held on November 30, 1998, it was
    agreed to issue common stock aggregating Mp$657,180 (Mp$600,000
    historical), represented by 600,000 limited vote, common, registered
    shares with no par value, identified as Series "V". The Board of
    Directors was granted the authority to sell these shares and/or to
    establish a trust for an employees' plan, which serves as an incentive to
    retain key personnel. To date, the trust has not been established.

   After the above agreements, the capital stock at December 31, 1998 is
   represented by 8,000,000 Series "A" shares, representing the fixed
   portion of the common stock, and 800,000 Series "B" shares, representing
   the variable portion, which is unlimited. The shares have no par value.

  Subsequent events (unaudited):

  --At the Extraordinary Stockholders' Meeting held on January 22, 1999, it
    was agreed to increase the variable portion of common stock by
    Mp$31,744,440, issuing 1,560,000 Series "A". The shares have no par
    value.

  --At the Extraordinary Stockholders' Meeting held on May 3, 1999, it was
    agreed to adopt the par value of the common stock of U.S.$2 dollars per
    share. The Stockholders' agreed to adopt retroactively the par value of
    the stock regarding the resolution made on January 22, 1999. As a result
    of this change, the increase of the variable portion of common stock was
    Mp$29,555,043 (Mp$28,704,000 historical). Therefore, the difference
    between the par value and the price paid at the subscription date of
    Mp$1,901,802 (Mp$1,817,533 historical) it was considered as an additional
    paid-in capital in the accompanying statement of changes in stockholders'
    equity.

  --During October 1999, the stockholders' subscribed all unpaid common
    stock.

 c. Retained earnings:

  Retained earnings are subject to the following restrictions:

  --5% of net income for the year should be appropriated to the legal reserve
    until it reaches one-fifth of the capital stock. At December 31, 1998,
    the legal reserve was zero.

  --Earnings of subsidiaries may not be distributed until received as
    dividends in the parent company.

 d. Restrictions to stockholders' equity:

  The amount updated on tax bases of stockholders' contributions and retained
earnings, on which income tax has been paid, when applicable, may be reimbursed
or distributed to the stockholders tax-free. Other refunds and distributions,
in excess of these amounts, pursuant to the procedure set forth by the Law, are
subject to income tax at the rate of 35%. Therefore, stockholders may only
receive of 65% of such amounts. Beginning January 1, 1999, profits distributed
to individuals or residents abroad are subject to an additional 5% income tax
withholding.

(12) Income tax (IT), tax on assets (TA), employees' statutory profit sharing
(ESPS) and tax loss carryforwards:

  Under the current tax laws, companies must pay the greater of IT or TA. Both
taxes recognize the effects of inflation, computed on a basis other than
generally accepted accounting principles in Mexico.

  ESPS is computed practically on the same basis as IT, but without recognizing
the effects of inflation.

  The TA Law establishes a 1.8% tax on assets updated for inflation, reduced by
certain liabilities. TA payable in excess of IT for the year may be recovered
in the ten succeeding years, updated for inflation, provided that IT exceeds TA
in any such years. In 1998 and 1997 the Company was not subject to TA in
accordance with the provisions of the Law.

  IT and ESPS expense are summarized as follows:

  The Company and its subsidiary file their income tax and tax on assets
returns on an individual basis. Therefore, the amounts of these items included
in the accompanying consolidated financial statements represents the sum of
individual results of each company. For employees' statutory profit sharing
purposes, the amount presented represents the sum of individual results of each
company.

  In accordance with the Mexican IT Law, the net operating losses of a year,
updated for inflation, may be carried forward to the taxable income of the ten
succeeding years. Tax losses have no effect on ESPS. The remaining net
operating losses sustained in prior years, amounting to Mp$1,165,026, were
carried to the 1997 taxable income, resulting in a tax benefit of Mp$396,109,
reported as an extraordinary item in the consolidated statement of operation of
such year.

  At December 31, 1998, the Company considered tax deductible the aggregate
expenses associated with leasehold improvements (note 8), resulting in a
benefit of Mp$2,062,506. As a result, deferred taxes amounting to Mp$721,877
were charged to operations in 1998.

(13) Contingent liabilities and commitments:

  a. There is a contingent liability arising from labor obligations referred
     to in note 1.

  b. Beginning January 1, 1997, pursuant to the amendments to the Income Tax
     Law, companies carrying out transactions with related parties, whether
     domestic or foreign, are subject to important tax limitations and
     obligations regarding the determination of transfer prices, since such
     prices should be similar to those that would be used in arm's-length
     transactions.

    In the event the tax authorities review the prices and reject the
    amounts determined, they could demand, in addition to the tax and
    corresponding additional charges (updating and surcharges), fines on
    the omitted taxes, which could be of up to 100% of the updated amounts
    of taxes.

  c. The Company has a plan (unaudited) to address the "Year 2000" issue.
     This plan addresses the impact of the Year 2000 problem in the computer
     systems that affect the Company's operations, its transactions with
     third parties and its financial information. Notwithstanding the steps
     being taken by the Company and due to the general uncertainty inherent

(15) Reconciliation between Mexican (Mexican GAAP) and United States of America
    (U.S. GAAP) Generally Accepted Accounting Principles:

  The Company's consolidated financial statements are prepared in accordance
with Mexican GAAP, which differ in certain significant respects from U.S. GAAP.
The Mexican GAAP consolidated financial statements include the effects of
inflation as provided for under Bulletin B-10, "Recognition of the Effects of
Inflation on the Financial Information". The application of this statement
represents a comprehensive measure of the effects of price level changes in the
Mexican economy and is believed to result in a more meaningful presentation
than historical cost-based financial reporting for both Mexican and U.S.
accounting purposes. Therefore, the following reconciliation to U.S. GAAP does
not include the reversal of such inflationary effects.

  The principal differences between Mexican GAAP and U.S. GAAP are summarized
in the following pages with an explanation, where appropriate, of the effects
on consolidated results of operations and stockholders' equity.

 a. Preoperating other assets and deferred costs

  Under Mexican GAAP, all preoperating costs incurred by the Company prior to
commencement of operations are capitalized and amortized over their related
useful lives. In addition, all direct and indirect costs related to the
Contenidos Project are capitalized and amortized over the estimated life of the
project. For U.S. GAAP purposes, the Company expenses all preoperating costs
and project costs that are incurred in the preliminary project stage. Costs
incurred during the application stage are capitalized and amortized over the
estimated life of the project. At December 31, 1998, the Company had
capitalized approximately Mp$1,890,000 for US GAAP purposes.

  The Company capitalized various costs under Mexican GAAP that may not
qualified for U.S. GAAP. These costs were identified and expensed for U.S. GAAP
purposes.

 b. Deferred income taxes and employees' statutory profit sharing

  Under Mexican GAAP deferred income taxes are recognized only for
identifiable, non-recurring timing differences between taxable and book income.
The benefit for utilizing tax loss carryforwards and assets tax credits is not
recognized until realized, at which time it is presented as an extraordinary
item.

  The Company follows Statement of Financial Accounting Standards ("SFAS") No.
109, "Accounting for Income Taxes" for U.S. GAAP reconciliation purposes. This
statement requires an asset and liability approach for financial accounting and
reporting for income taxes under the following basic principles: (a) a current
tax liability or asset is recognized for the estimated taxes payable or
refundable on tax returns for the current year, (b) a deferred tax liability or
asset is recognized for the estimated future tax effects attributable to
temporary differences and tax loss and tax credit carryforwards, (c) the
measurement of current and deferred tax liabilities and assets is based on
provisions of the enacted tax law and the effects of future changes in tax laws
or rates are not anticipated, (d) the measurement of deferred tax assets is
reduced, if necessary, by the amount of any tax benefits that, based on
available evidence, are not expected to be realized. Under this method,
deferred taxes are recognized with respect to all temporary differences, and
the benefit from utilizing tax loss carryforwards and asset tax credits is
recognized in the year in which the loss or credits arise (subject to a
valuation allowance with respect to any tax benefits not expected to be
realized). The subsequent realization of this benefit does not affect income.
Consequently, such realization does not give rise to extraordinary items from
this for U.S. GAAP purposes. The effect on deferred taxes of a change in tax
rates is recognized in income in the period that includes the enactment date.

  The temporary differences under SFAS No. 109 are determined based on the
differences between the indexed tax basis amount of the asset or liability and
the related amount reported in the financial statements.

               (Constant Mexican pesos as of September 30, 1999)


  Deferred tax expense or benefit is calculated as the difference between (a)
deferred tax assets and liabilities net of any valuation allowances reported at
the end of the current year determined as indicated above and (b) deferred tax
assets and liabilities net of any valuation allowances reported at the end of
the prior year, remeasured to units of current general purchasing power at the
end of the current period.

  Since employees' profit sharing is calculated based on taxable income after
certain adjustments and is subject to future consequences of temporary
differences in the same manner as income taxes, the deferred employee's
statutory profit sharing, which is not recorded under Mexican GAAP, must be
included in the reconciliation of Mexican to U.S. GAAP.

  The components of the income tax expense under U.S. GAAP are as follows:

               (Constant Mexican pesos as of September 30, 1999)


  In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion of the deferred tax assets
will not be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the periods in
which those temporary differences become deductible. During 1997, 1998 and the
nine-month period ended September 30, 1999, the valuation allowance for
deferred income tax assets and statutory employees' profit sharing increased by
Mp$136,655, Mp$68,170 and Mp$3,009,835 (unaudited), respectively. The increase
to the allowance was the result of additional net operating loss carryforwards
of its subsidiary and unrealized gain in To2 project and CSI shares as
described in note 15j. The Company is not expecting to apply such net operating
loss carryforwards against future taxable income as well as the uncertainty of
the realization of the deferred tax assets derived from the sales of some
assets. The amount of the deferred tax asset considered realizable could,
however, be reduced in the near term if estimates of future taxable income
during the carryforward period are reduced.

  Effective December 31, 1998, the Company increased its income tax rate from
34% to 35% for temporary differences to give effect to the enactment of the new
income tax law in Mexico. This resulted in a reduction in the deferred tax
benefit of Mp$77,586 for U.S. GAAP purposes in 1998.

 c. Accrued vacation cost

  Under Mexican GAAP, vacation expense is recognized when taken rather than
during the period in which it is earned by the employees. The Company's policy
and practice is that any vacation not taken by employees prior to the end of
the year is lost. The Company has, therefore, not recorded a liability for
vacation pay as of December 31, 1997, 1998 and September 30, 1999.

               (Constant Mexican pesos as of September 30, 1999)

 d. Accrued termination benefits

  Under Mexican GAAP, an accrual is not provided for estimable termination
benefits, and they are recognized in the results of the Company when they are
paid to terminated employees. In order to comply with U.S. GAAP, the Company
estimated the benefits it would pay to terminated employees in the future as of
December 31, 1997, 1998 and September 30, 1999. These amounts were not
considered significant by the Company's management.

 e. Other employee benefits

   The Company has no postretirement health care insurance or other benefit
plans; therefore. SFAS No. 106. "Employers' Accounting for Postretirement
Benefits Other than Pensions" and SFAS No. 112, "Employers' Accounting for
Postemployment Benefits" would have no effect on the Company's financial
position.

 f. Minority interest

  Under Mexican GAAP, Bulletin B-8, minority interests in subsidiaries must be
included as a component of stockholders' equity. Consequently, minority
interest in the income of subsidiaries is not presented as an expense in the
statement of operations. Under U.S. GAAP, minority interest in subsidiaries is
classified as a separate component bin total liabilities & stockholders equity
in the consolidated balance sheet and is excluded from stockholders' equity.

 g. Monetary gain/(loss)

  The U.S. GAAP financial information reflects the effects of inflation as this
provides more meaningful information in inflationary economies.

 h. Extraordinary items

  Infoacces utilized tax loss carryforwards of Ps$1,165,026 (Mp$896,769
historically) for the year ended December 31, 1997. Under Mexican GAAP, the
utilization of these items is presented as extraordinary items in the statement
of operations. Under U.S. GAAP, the utilization of tax loss carryforwards and
tax credits is included in the provision for income taxes.

 i. Segment information under U.S. GAAP

  The Company divides its operations principally into three different business
units: internet services, network and web development. The Company makes
resource allocation decisions on individual business unit level, and therefore,
segment data has been presented for the Company's significant units. During
1997, the company had one business unit only, therefore no financial data is
provided for such year.

 j. Sale of To2 project and CSI stock

  The gain obtained from the To2 project sale and CSI's shares of Mp$3,546,098
and Mp$1,025,790, respectively, recognized for Mexican GAAP purposes (note 14)
is considered as an unrealized gain for U.S. GAAP purposes; These transactions
are not considered to be the culmination of the earnings process, and the
company's investment in the new entity will be reflected at the original
recorded amount.

 k. Comprehensive income (loss)

  In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income". SFAS 130 establishes standards for reporting
and display of comprehensive income and its components in a full set of
financial statements. Comprehensive income (loss) is defined as the change in
equity during the period from transactions and other events and circumstances
from non-owner sources. Comprehensive income (loss) and net income (loss) is
the same at December 31, 1997 and 1998. Adoption of this statement did not have
an impact on the Company's financial condition or result of operations as it
only relates to changes in, or additions to, the financial statements
disclosures.

 l. Recent pronouncements

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133
"Accounting for Derivative Instruments and Hedging Activities" (SFAS 133). The
statement provides guidance for accounting for all

                                     F-165

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

derivative and hedging activities. All derivative instruments are to be
recognized as assets or liabilities in the balance sheet and measured at fair
value. In accounting for a fair value hedge, the derivative hedging instrument
will be measured at fair value with the market to fair value being recorded in
earnings. SFAS No. 133 is effective for fiscal quarters or fiscal years
beginning after June 15, 2000. The Company is not expected to have a
significant impact from the adoption of this standards.

  In March 1998, the AICPA Accounting for Standards Executive Committee (AcSEC)
issued Statements for Position 98-1 "Accounting for the Cost of Computer
Software Developed of obtained for internal Use" (SOP 98-1), which provides
guidance on accounting for the costs of computer software developed or obtained
for internal use. SOP 98-1 requires that certain costs related to the
development or purchase of internal-use software be capitalized and amortized
over the estimated useful life of the software and that costs related to the
preliminary project stage and post-implementation operations stage (as defined
in SOP 98-1), in an internal-use computer software development project be
expensed as incurred. SOP 98-1 is not expected to have a significant impact on
the Company's financial position, results of operations or cash flows.

  In April 1998, the AcSEC issued Statement of Position 98-5 "Reporting on the
Costs of Start-Up Activities" (SOP 98-5), which requires that costs incurred
during start-up activities, including organization costs, be expensed as
incurred. SOP 98-5 is effective for financial statements for fiscal years
beginning after December 15, 1998. Under U.S. GAAP, the Company expenses costs
of start-up activities as incurred and, consequently, the Company believes that
the adoption of this SOP will not have a material impact on its results of
operations, financial position or cash flows.

  The Mexican Institute of Public Accountants issued Bulletin D-4 "Accounting
for Deferred Income Taxes, Tax on Assets and Employees' Statutory Profit
Sharing," which provides guidance an accounting for deferred employees'
statutory profit sharing and income taxes. This statement requires an asset and
liability approach for financial accounting and reporting for deferred income
taxes and statement of operations approach for deferred employees' statutory
profit sharing. This bulletin is similar as SFAS No. 109 for U.S. GAAP, as
described in note 15b. "D-4" is effective for fiscal years beginning after
December 31, 1999, although early application is encouraged.

 m. Cash flow information

  The following table summarizes the cash flow items as required under SFAS 95
provided by (used in) operating, investing and financing activities for the
years ended December 31, 1997 and 1998, and for the nine months ended September
30, 1998 and 1999, giving effect to the U.S. GAAP adjustments, excluding the
effects of inflation required by Bulletin B-10. The following information is
presented on a historical peso basis and it is not presented in constant
purchasing power.

has been accounted for using the purchase method of accounting (see note 2).

Item 14. Indemnification of Directors and Officers.

  Upon completion of this offering, the Certificate of Incorporation and Bylaws
of the Registrant will 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 Delaware General Corporation Law (the "DGCL"),
except that the Registrant will indemnify a director or officer in connection
with a proceeding (or part thereof) initiated by the person only if the
proceeding (or part thereof) was authorized by the Registrant's Board of
Directors. The indemnification provided under the Certificate of Incorporation
and Bylaws includes the right to be paid by the Registrant the expenses
(including attorneys' fees) in advance of any proceeding for which
indemnification may be had in advance of its final disposition, provided that
the payment of those 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
the director or officer to repay all amounts so paid in advance if it is
ultimately determined that the director or officer is not entitled to be
indemnified.

  As permitted by the DGCL, the Registrant's Certificate of Incorporation will
provide 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.

  Under the Bylaws, the Registrant will have the power to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee
or agent of the Registrant, or is or was serving at the request of the
Registrant as a director, officer, employee, partner (limited or general) or
agent of another corporation or of a partnership, joint venture, limited
liability company, trust or other enterprise, against any liability asserted
against the person or incurred by the person in that capacity, or arising out
of the person's status, and related

                                      II-1
<PAGE>

expenses, whether or not the Registrant would have the power to indemnify the
person against liability under the provisions of the DGCL. The Registrant has
purchased director and officer liability insurance on behalf of its directors
and officers.

  The Underwriting Agreement provides that the underwriters are obligated,
under specified circumstances, to indemnify directors, officers and
controlling persons of VIA against specified liabilities, including
liabilities under the Securities Act of 1933, as amended. Reference is made to
the form of Underwriting Agreement to be filed as Exhibit 1.1 hereto.

Item 17. Undertakings.

  The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, 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 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 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 of
  1933, the information omitted from the form of prospectus filed as part of
  this registration statement in reliance upon Rule 430A and contained in a
  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.

    (2) For the purpose of determining any liability under the Securities Act
  of 1933, 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.

                                   SIGNATURES

  Pursuant to the requirements of the Securities Act of 1933, the registrant
has duly caused this Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in the city of Reston, Commonwealth of

highly qualified officers, key employees, directors and other persons, and to
motivate such officers, key employees, directors, and other persons to serve the
Company and its affiliates (as defined herein) and to expend maximum effort to
improve the business results and earnings of the Company, by providing to such
officers, key employees, directors and other persons an opportunity to acquire
or increase a direct proprietary interest in the operations and future success
of the Company. To this end, the Plan provides for the grant of stock options in
accordance with the terms hereof.

2.   DEFINITIONS

     For purposes of interpreting the Plan and related documents (including
Award Agreements), the following definitions shall apply:

     2.1  "affiliate" of, or person "affiliated" with, a person means any

common control with such person within the meaning of Rule 405 of Regulation C
under the Securities Act.

entity (other than persons who are shareholders or affiliates of the Company at

Company, (b) the Option Price established for the Stock in the then-most recent

     3.1. Board.

administration of the Plan as are consistent with the Company's certificate of
incorporation and by-laws and applicable law. The Board shall have full power
and authority to take all actions and to make all determinations required or
provided for under the Plan, any Grant or any Award Agreement, and shall have
full power and authority to take all such other actions and make all such other
determinations not inconsistent with the specific terms and provisions of the
Plan that the Board deems to be necessary or appropriate to the administration
of the Plan, any Grant or any Award Agreement. All such actions and
determinations shall be by the affirmative vote of a majority of the members of
the Board present at a meeting or by unanimous consent of the Board executed in
writing in accordance with the Company's certificate of incorporation and by-
laws and applicable law. The interpretation and construction by the Board of any
provision of the Plan, any Grant or any Award Agreement shall be final and
conclusive.

     3.2. Committee.

     The Board from time to time may delegate to a Committee such powers and
authorities related to the administration and implementation of the Plan, as set
forth in Section 3.1 above and in other applicable provisions, as the Board
shall determine, consistent with the certificate of incorporation and by-laws of
the Company and applicable law. In the event that the Plan, any Grant or any
Award Agreement entered into hereunder provides for any action to be taken by or
determination to be made by the Board, such action may be taken by or such
determination may be made by the Committee if the power and authority to do so
has been delegated to the Committee by the Board as provided for in this
Section. Unless otherwise expressly determined by the Board, any such action or
determination by the Committee shall be final, binding and conclusive.

     3.3. Grants.

     Subject to the other terms and conditions of the Plan, the Board shall have
full and final authority (i) to designate Grantees, (ii) to determine the type
or types of Grant to be made to a Grantee, (iii) to determine the number of
shares of Stock and the type or types of Stock to be subject to a Grant, (iv) to
establish the terms and conditions of each Grant (including, but not limited to,
the exercise price of any Option and the nature and duration of any restriction
or condition (or provision for lapse thereof) relating to the vesting, exercise,
transfer, or forfeiture of a Grant or the shares of Stock subject thereto), (v)
to prescribe the form of each Award Agreement evidencing a Grant, and (vi) to
amend, modify, or supplement the terms of any outstanding Grant. Such authority
specifically includes the authority, in order to effectuate the purposes of the
Plan but without amending the Plan, to modify Grants to eligible individuals who
are foreign nationals or are individuals who are employed outside the United
States to recognize differences in local law, tax policy, or custom. As a
condition to any subsequent Grant, the Board shall have the right, at its

                                       3
<PAGE>

discretion, to require Grantees to return to the Company any unexercised Grants
previously awarded under the Plan. Subject to the terms and conditions of the
Plan, any such new Grant shall be upon such terms and conditions as are
specified by the Board at the time the new Grant is made.

     3.4. No Liability.

     No member of the Board or of the Committee shall be liable for any action
or determination made in good faith with respect to the Plan or any Grant or
Award Agreement.

4.   STOCK SUBJECT TO THE PLAN

     Subject to adjustment as provided in Section 13 hereof, the number of
shares of Stock available for issuance under the Plan shall be 400,000 shares of
Common. Stock issued or to be issued under the Plan shall be authorized but
unissued shares. If any shares covered by a Grant are not purchased or are
forfeited, or if a Grant otherwise terminates without delivery of any Stock
subject thereto, then the number of shares of Stock counted against the
aggregate number of shares available under the Plan with respect to such Grant
shall, to the extent of any such forfeiture or termination, again be available
for making Grants under the Plan.

5.  EFFECTIVE DATE AND TERM OF THE PLAN

     5.1.  Effective Date.

     The Plan shall be effective as of the Effective Date.

     5.2.  Term.

     The Plan has no termination date.

6.   OPTION GRANTS

providing, or who has provided, services to, the Company or any Subsidiary,
including any such employee who is an officer or director of the Company or of
any Subsidiary, as the Board shall determine and designate from time to time.

     6.2.  Successive Grants.

     An eligible person may receive more than one Grant, subject to such
restrictions as are provided herein.

7.   AWARD AGREEMENT

     Each Grant pursuant to the Plan shall be evidenced by an Award Agreement,
in such form or forms as the Board shall from time to time determine. Award

the Award Agreement evidencing such Option. In no case shall the Option Price of
any Option be less than the par value of a share of Stock.

9.   VESTING, TERM AND EXERCISE OF OPTIONS

     9.1.  Vesting and Option Period.

     Subject to Sections 9.2 and 9.3 hereof, each Option granted under the Plan
shall be exercisable from the Grant Date and under such conditions as shall be
determined by the Board and stated in the Award Agreement. For purposes of this
Section 9.1, fractional numbers of shares of Stock subject to an Option shall be
rounded down to the next nearest whole number. The period during which any
Option shall be exercisable shall constitute the "Option Period" with respect to
such Option.

     9.2.  Term.

     Each Option granted under the Plan shall terminate, and all rights to
purchase shares of Stock thereunder shall cease, upon the expiration of ten
years from the date such Option is granted, or under such circumstances and on
such date prior thereto as is set forth in the Plan or as may be fixed by the
Board and stated in the Award Agreement relating to such Option (the
"Termination Date").

     9.3.  Termination of Employment or Other Relationship.

     Upon the termination of a Grantee's employment or other relationship with
the Company (or Grantee's death), any Option or portion thereof held by such
Grantee that has not been exercised shall terminate immediately. Upon
termination of an Option or portion thereof, the Grantee shall have no further
right to purchase shares of Stock pursuant to such Option or portion thereof.
Whether a leave of absence or leave on military or government service shall
constitute a termination of employment or other relationship for purposes of the
Plan shall be determined by the Board, which determination shall be final and
conclusive. For purposes of the Plan, a termination of employment, service or
other relationship shall not be deemed to occur if the Grantee is immediately
thereafter a director of the Company.

     9.4.  Limitations on Exercise of Option.

     Notwithstanding any other provision of the Plan, in no event may any Option
be exercised, in whole or in part, after ten years following the date upon which
the Option is granted, or after the occurrence of an event referred to in
Section 13 hereof which results in termination of the Option.

     9.5.  Method of Exercise.

     An Option that is exercisable may be exercised by the Grantee's delivery to
the Company of written notice of exercise on any business day, at the Company's
principal office, addressed to the attention of the Board. Such notice shall
specify the number of shares of Stock with respect to which the Option is being
exercised and shall be accompanied by payment in full of the Option Price of the
shares for which the Option is being exercised. The minimum number of shares of
Stock with respect to which an Option may be exercised, in whole or in part, at
any time shall be the lesser of (i) 100 shares or such lesser number set forth
in the applicable Award Agreement or (ii) the maximum number of shares available
for purchase under the Option at the time of exercise. Payment of the Option
Price for the shares purchased pursuant to the exercise of an Option shall be
made in cash or

                                       5
<PAGE>

in cash equivalents. Unless otherwise stated in the applicable Award Agreement,
an individual holding or exercising an Option shall have none of the rights of a
shareholder (for example, the right to receive cash or dividend payments or
distributions attributable to the subject shares of Stock or to direct the
voting of the subject shares of Stock) until the shares of Stock covered thereby
are fully paid and issued to such individual. Except as provided in Section 13
hereof, no adjustment shall be made for dividends, distributions or other rights
for which the record date is prior to the date of such issuance.

     9.6.  Delivery of Stock Certificates.

     Promptly after the exercise of an Option by a Grantee and the payment in
full of the Option Price, such Grantee shall be entitled to the issuance of a
stock certificate or certificates evidencing his or her ownership of the shares
of Stock subject to the Option.

10.  TRANSFERABILITY OF OPTIONS; REPURCHASE RIGHTS

     10.1. Transferability of Options

     Only the Grantee may exercise an Option. No Option shall be assignable or
transferable by the Grantee to whom it is granted.

     10.2. Repurchase Rights.

           The Company shall have the right (a "Repurchase Right"), as set forth
in this Section, to purchase from a Grantee (or the Grantee's estate or other
representative, as applicable) all of the shares of Stock acquired by the
Grantee pursuant to Options granted under this Plan, in the event that (i) each
employment or similar relationship (whether as employee, director, independent
contractor or otherwise) between the Grantee and the Company and its affiliates
is terminated by the Grantee during the two year period (the "Minimum Employment
Period") commencing on the date Grantee commenced employment with the Company,
other than by reason of death or "permanent and total disability" (within the
meaning of Section 22(e)(3) of the Code), or (ii) if the employment of the
Grantee with the Company is terminated by the Company "for cause." The
Repurchase Right shall not apply if the employment of the Grantee with the
Company is terminated by the Company other than "for cause." Each Repurchase
Right shall commence on the date of the Grantee's termination of employment and
end 30 days thereafter. The price per share for each share purchased pursuant to
a Repurchase Right shall be at a price equal to the Fair Market Value of such
shares on the date of termination. Termination "for cause" shall mean
termination because of the Grantee's willful misconduct, breach of a fiduciary
duty to the Company resulting in personal profit to the Grantee, conviction of a
felony or crime involving moral turpitude, or material breach of any agreement
between the Grantee and the Company regarding confidential information, trade
secrets, inventions, non-competition or similar matters. The Company may assign
its repurchase rights (but not its obligations), under this Section 10.2 and the
applicable Award Agreement, in whole or in part, to (1) any Stockholder, (2) any
affiliate or (3) any other person or entity that the Board of Directors of the
Company determines has a sufficient relationship with or interest in the
Company. The Company shall give reasonable written notice to the Grantee (or the
Grantee's estate or other representative, as applicable) of any assignment of
its rights under this Section.

     10.3. Transferability of Stock

           No Grantee shall, during the "No-Sale Period" as defined below, sell
or transfer any shares of Stock acquired by the individual pursuant to this Plan
under an Option, and any such transfer shall be deemed void and of no effect.
The "No-Sale Period" shall mean the period commencing on the Grant Date and
ending on the later of (i) the expiration of the Minimum Employment Period or
(ii) if the Company has a Repurchase Right under Section 10.2, the

                                       6
<PAGE>

expiration of the Repurchase Period (or, if the Repurchase Right was exercised,
prior to the closing of the repurchase), to any purchaser or transferee other
than the Company; provided, however, that a transfer shall not be prohibited if
the transferee is an affiliate or immediate family member of such Grantee and
the transferee enters into an agreement reasonably acceptable to the Company to
be bound by this Agreement.

     10.4.  Sale Rights.

            The Grantee (or the Grantee's estate or other representative, as
applicable) shall have the right (a "Sale Right"), as set forth in this Section,
to sell to the Company all of the shares of Stock acquired by the Grantee
pursuant to Options granted under this Plan, in the event of death or "permanent
and total disability" (within the meaning of Section 22(e)(3) of the Code) of
the Grantee during the Minimum Employment Period (an "Involuntary Termination"),
subject to receipt by the Company of all required approvals under the Company's
Certificate of Incorporation (including all Certificates of Designations), By-
laws and material contracts. Each Sale Right shall commence on the date of the
Grantee's Involuntary Termination and end 60 days thereafter. The price per
share for each share purchased pursuant to a Sale Right shall be at a price
equal to the Fair Market Value of such shares on the date of the Involuntary
Termination. The Company may assign the right (but not its obligation) to
acquire Stock following exercise of a Sale Right under this Section 10.4, in
whole or in part, to (1) any Stockholder, (2) any affiliate or (3) any other
person or entity that the Board of Directors of the Company determines has a
sufficient relationship with or interest in the Company. The Company shall give
reasonable written notice to the Grantee (or the Grantee's estate or other
representative, as applicable) of any assignment of its rights under this
Section.

     10.5.  Publicly Traded Stock

          If the Stock is listed on an established national or regional stock
exchange or is admitted to quotation on the National Association of Securities
Dealers Automated Quotation System, or is publicly traded in an established
securities market, the foregoing transfer restrictions of Sections 10.2 and 10.3
shall terminate as of the first date that the Stock is so listed, quoted or
publicly traded.

     10.6.  Legend

            In order to enforce the restrictions imposed upon shares of Stock
under this Plan or as provided in an Award Agreement, the Board may cause a
legend or legends to be placed on any certificate representing shares issued
pursuant to this Plan that complies with the applicable securities laws and
regulations and makes appropriate reference to the restrictions imposed under
it.

11.  REQUIREMENTS OF LAW

     11.1.  General.

     The Company shall not be required to sell or issue any shares of Stock
under any Grant if the sale or issuance of such shares would constitute a
violation by the Grantee, any other individual exercising an Option, or the
Company of any provision of any law or regulation of any governmental authority,
including without limitation any federal or state securities laws or
regulations. If at any time the Company shall determine, in its discretion, that
the listing, registration or qualification of any shares subject to a Grant upon
any securities exchange or under any governmental regulatory body is necessary
or desirable as a condition of, or in connection with, the issuance or purchase
of shares hereunder, no shares of Stock may be issued or sold to the Grantee or
any other individual exercising an Option pursuant to such Grant unless such
listing, registration, qualification, consent or approval shall have been
effected or obtained free of any conditions not acceptable to the Company, and
any delay caused thereby shall in no way affect the date of termination of the
Grant.

                                       7
<PAGE>

Specifically, in connection with the Securities Act, upon the exercise of any
Option, unless a registration statement under such Act is in effect with respect
to the shares of Stock covered by such Grant, the Company shall not be required
to sell or issue such shares unless the Board has received evidence satisfactory
to it that the Grantee or any other individual exercising an Option may acquire
such shares pursuant to an exemption from registration under the Securities Act.
Any determination in this connection by the Board shall be final, binding, and
conclusive. The Company may, but shall in no event be obligated to, register any
securities covered hereby pursuant to the Securities Act. The Company shall not
be obligated to take any affirmative action in order to cause the exercise of an
Option or the issuance of shares of Stock pursuant to the Plan to comply with
any law or regulation of any governmental authority. As to any jurisdiction that
expressly imposes the requirement that an Option shall not be exercisable until
the shares of Stock covered by such Option are registered or are exempt from
registration, the exercise of such Option (under circumstances in which the laws
of such jurisdiction apply) shall be deemed conditioned upon the effectiveness
of such registration or the availability of such an exemption.

     11.2.  Rule 16b-3.

     During any time when the Company has a class of equity security registered
under Section 12 of the Exchange Act, it is the intent of the Company that
Grants pursuant to the Plan and the exercise of Options granted hereunder will
qualify for the exemption provided by Rule 16b-3 under the Exchange Act. To the
extent that any provision of the Plan or action by the Board does not comply
with the requirements of Rule 16b-3, it shall be deemed inoperative to the
extent permitted by law and deemed advisable by the Board, and shall not affect
the validity of the Plan. In the event that Rule 16b-3 is revised or replaced,
the Board may exercise its discretion to modify this Plan in any respect
necessary to satisfy the requirements of, or to take advantage of any features
of, the revised exemption or its replacement.

12.  AMENDMENT AND TERMINATION OF THE PLAN

     The Board may, at any time and from time to time, amend, suspend, or
terminate the Plan as to any shares of Stock as to which Grants have not been
made. The Company may retain the right in an Award Agreement to cause a
forfeiture of the gain realized by a Grantee on account of the Grantee taking
actions in "competition with the Company," as defined in the applicable Award
Agreement. Furthermore, the Company may annul a Grant if the Grantee is an
employee of the Company or an affiliate and is terminated "for cause" as defined
in the applicable Award Agreement. Except as permitted under this Section 12 or
Section 13 hereof, no amendment, suspension, or termination of the Plan shall,
without the consent of the Grantee, alter or impair rights or obligations under
any Grant theretofore awarded under the Plan.

13.  EFFECT OF CHANGES IN CAPITALIZATION

     13.1.  Changes in Stock.

     If the number of outstanding shares of Stock is increased or decreased or
the shares of Stock are changed into or exchanged for a different number or kind
of shares or other securities of the Company on account of any recapitalization,
reclassification, stock split, reverse split, combination of shares, exchange of
shares, stock dividend or other distribution payable in capital stock, or other
increase or decrease in such shares effected without receipt of consideration by
the Company occurring after the Effective Date, the number and kinds of shares
for which Grants of Options may be made under the Plan shall be adjusted
proportionately and accordingly by the Company. In addition, the number and kind
of shares for which Grants are outstanding shall be adjusted proportionately and
accordingly so that the proportionate interest of the Grantee immediately
following such event shall, to the extent practicable, be the same as
immediately before such event. Any such adjustment in outstanding Options shall
not change the aggregate Option Price payable

                                       8
<PAGE>

with respect to shares that are subject to the unexercised portion of an Option
outstanding but shall include a corresponding proportionate adjustment in the
Option Price per share. The conversion of any convertible securities of the
Company shall not be treated as an increase in shares effected without receipt
of consideration.

     13.2.  Reorganization in Which the Company Is the Surviving Entity and in
            Which No Change of Control Occurs.

     Subject to Section 13.3 hereof, if the Company shall be the surviving
entity in any reorganization, merger, or consolidation of the Company with one
or more other entities and in which no Change in Control occurs, any Option
theretofore granted pursuant to the Plan shall pertain to and apply to the
securities to which a holder of the number of shares of Stock subject to such
Option would have been entitled immediately following such reorganization,
merger, or consolidation, with a corresponding proportionate adjustment of the
Option Price per share so that the aggregate Option Price thereafter shall be
the same as the aggregate Option Price of the shares remaining subject to the
Option immediately prior to such reorganization, merger, or consolidation.

     13.3.  Reorganization, Sale of Assets or Sale of Stock Which Involves a
            Change of Control.

     Upon consummation of any Change of Control, the Plan and all outstanding
but unexercised Options shall terminate. The Board shall send written notice of
an event that will result in such a termination to all individuals who hold
Options not later than the time at which the Company gives notice thereof to its
shareholders. This Section 13.3 shall not apply to any Change of Control to the
extent that (A) provision is made in writing in connection with such Change of
Control for the continuation of the Plan or the assumption of the Options
theretofore granted, or for the substitution for such Options of new options
covering the stock of a successor entity, or a parent or subsidiary thereof,
with appropriate adjustments as to the number and kinds of shares or units and
exercise prices, in which event the Plan and Options theretofore granted shall
continue in the manner and under the terms so provided or (B) a majority of the
full Board determines that such Change of Control shall not trigger application
of the provisions of this Section 13.3.

     13.4.  Adjustments.

     Adjustments under this Section 13.4 related to shares of Stock or
securities of the Company shall be made by the Board, whose determination in
that respect shall be final, binding and conclusive. No fractional shares or
other securities shall be issued pursuant to any such adjustment, and any
fractions resulting from any such adjustment shall be eliminated in each case by
rounding downward to the nearest whole share.

     13.5.  No Limitations on Company.

     The making of Grants pursuant to the Plan shall not affect or limit in any
way the right or power of the Company to make adjustments, reclassifications,
reorganizations, or changes of its capital or business structure or to merge,
consolidate, dissolve, or liquidate, or to sell or transfer all or any part of
its business or assets.

14.  DISCLAIMER OF RIGHTS

     No provision in the Plan or in any Grant or Award Agreement shall be
construed to confer upon any individual the right to remain in the employ or
service of the Company or any affiliate, or to interfere in any way with any
contractual or other right or authority of the Company either to increase or
decrease the compensation or other payments to any individual at any time, or to
terminate any employment or other relationship between any individual and the
Company. In

                                       9
<PAGE>

     addition, notwithstanding anything contained in the Plan to the contrary,
unless otherwise stated in the applicable Award Agreement, no Grant awarded
under the Plan shall be affected by any change of duties or position of the
Optionee, so long as such Grantee continues to be a director, officer,
consultant or employee of the Company. The obligation of the Company to pay any
benefits pursuant to this Plan shall be interpreted as a contractual obligation
to pay only those amounts described herein, in the manner and under the
conditions prescribed herein. The Plan shall in no way be interpreted to require
the Company to transfer any amounts to a third party trustee or otherwise hold
any amounts in trust or escrow for payment to any participant or beneficiary
under the terms of the Plan. No Grantee shall have any of the rights of a
shareholder with respect to the shares of Stock subject to an Option except to
the extent the certificates for such shares of Stock shall have been issued upon
the exercise of the Option.

15.  NONEXCLUSIVITY OF THE PLAN

     Neither the adoption of the Plan nor the submission of the Plan to the
shareholders of the Company for approval shall be construed as creating any
limitations upon the right and authority of the Board to adopt such other
incentive compensation arrangements (which arrangements may be applicable either
generally to a class or classes of individuals or specifically to a particular
individual or particular individuals) as the Board in its discretion determines
desirable, including, without limitation, the granting of stock options
otherwise than under the Plan.

16.  WITHHOLDING TAXES

     The Company or a Subsidiary, as the case may be, shall have the right to
deduct from payments of any kind otherwise due to a Grantee any Federal, state,
or local taxes of any kind required by law to be withheld upon the issuance of
any shares of Stock upon the exercise of an Option. At the time of such
exercise, the Grantee shall pay to the Company or the Subsidiary, as the case
may be, any amount that the Company or the Subsidiary may reasonably determine
to be necessary to satisfy such withholding obligation. Subject to the prior
approval of the Company or the Subsidiary, which may be withheld by the Company
or the Subsidiary, as the case may be, in its sole discretion, the Grantee may
elect to satisfy such obligations, in whole or in part, (i) by causing the
Company or the Subsidiary to withhold shares of Stock otherwise issuable to the
Grantee or (ii) by delivering to the Company or the Subsidiary shares of Stock
already owned by the Grantee. The shares of Stock so delivered or withheld shall
have an aggregate Fair Market Value equal to such withholding obligations. The
Fair Market Value of the shares of Stock used to satisfy such withholding
obligation shall be determined by the Company or the Subsidiary as of the date
that the amount of tax to be withheld is to be determined. A Grantee who has
made an election pursuant to this Section 16 may satisfy his or her withholding
obligation only with shares of Stock that are not subject to any repurchase,
forfeiture, unfulfilled vesting, or other similar requirements.

17.  CAPTIONS

     The use of captions in this Plan or any Award Agreement is for the
convenience of reference only and shall not affect the meaning of any provision
of the Plan or such Award Agreement.

18.  OTHER PROVISIONS

     Each Grant awarded under the Plan may contain such other terms and
conditions not inconsistent with the Plan as may be determined by the Board, in
its sole discretion.

19.  NUMBER AND GENDER

     With respect to words used in this Plan, the singular form shall include
the plural form, the masculine gender shall include the feminine gender, etc.,
as the context requires.

                                       10

20.  SEVERABILITY

     If any provision of the Plan or any Award Agreement shall be determined to
be illegal or unenforceable by any court of law in any jurisdiction, the
remaining provisions hereof and thereof shall be severable and enforceable in
accordance with their terms, and all provisions shall remain enforceable in any
other jurisdiction.

21.  GOVERNING LAW

     The validity and construction of this Plan and the instruments evidencing
the Grants awarded hereunder shall be governed by the laws of the State of
Delaware.

                                                                               4

     (b) Payment of Inland Capacity Purchase Price. In exchange for the IRU
         -----------------------------------------
interest granted pursuant to this Agreement in any Inland Capacity, the
Purchaser shall, on or before each Payment Due Date, pay to the Grantor's

the location of any business or properties of the Purchaser (collectively
"Taxes"). If the Purchaser is or was required by law to make any deduction or
withholding for or on account of any Taxes from any payment due hereunder to
Grantor, then, notwithstanding anything to the contrary contained in this
Agreement, the gross amount payable by the Purchaser to Grantor will be
increased so that, after any such deduction or withholding for Taxes, the net
amount received by Grantor will not be less than Grantor would have received had
no such deduction or withholding been required. If any taxing or government
authority asserts that the Purchaser should have made a deduction or withholding
for on account of any Taxes with respect to all or a portion of any payment made
hereunder, the Purchaser hereby agrees to indemnify the Grantor for such Taxes
and hold the Grantor harmless on an after-tax basis from and against any Taxes,
interest or penalties levied or asserted in connection therewith.

     4. OPERATION AND MAINTENANCE OF INLAND CAPACITY.
     -----------------------------------------------

     (a) Except as otherwise set forth in this Agreement, the Purchaser shall
not be required to make any additional payments for costs associated with
operating, maintaining and repairing the Inland Capacity in which an IRU has
been granted hereunder.

     (b) Grantor shall use reasonable commercial efforts to cause the Inland
Capacity in which an IRU has been granted hereunder to be maintained in
efficient working order and in accordance with industry standards and, to the
extent applicable, the Maintenance Performance Standards set forth in Schedule
IV to the Capacity Purchase Agreement which Schedule IV is incorporated herein
by reference. Grantor represents that at all times it shall use commercially
reasonable efforts to require the applicable Backhaul Provider with which it has
contracted to provide routine, preventive and corrective maintenance for the
Inland Capacity in accordance with performance standards that at least meet
prudent industry standards. Grantor will use reasonable commercial efforts to
cause the Backhaul Provider with which it has contracted to perform its
obligations under the applicable Backhaul Agreement.
<PAGE>

                                                                               5

     (c) Grantor will have sole responsibility for negotiating, executing and
administering contracts related to the acquisition of rights in any Inland
Capacity from Backhaul Providers.

     (d) Should any condition exist in any Inland Capacity in which an IRU has
been granted hereunder that may impair the integrity of such Inland Capacity,
Grantor shall take reasonable actions to cause to be initiated maintenance on
such Inland Capacity and Grantor shall take reasonable actions to cause to be
initiated planned maintenance on such Inland Capacity in each case which may
include the deactivation of such Inland Capacity. Grantor shall, to the extent
reasonably practicable, advise the Purchaser in writing at least thirty (30)
days (or such shorter period as may be agreed) prior to the initiation of a
planned maintenance operation of the timing and scope of such planned
maintenance operation.

     (e) In addition to fulfilling its obligations as set forth in Section 4(b),
in the event of disruption of service, Grantor shall use commercially reasonable
efforts to cause service to be restored as quickly as reasonably possible, and
Grantor shall take such measures as are reasonably necessary to obtain such
objective.

     5. INVOICES; DEFAULT INTEREST. (a) Invoices. Grantor or its authorized
     -----------------------------      --------
agent shall render invoices under this Agreement in Dollars, and the Purchaser
shall pay such amount in Dollars. The Purchaser shall make all payments by means
of a wire transfer to the Grantor's Account. Any payments required to be made
pursuant to this Agreement shall, save for the Initial Payment which shall be
made in accordance with the provisions of Section 3(b), be made on the later of
(i) the date when due or (ii) thirty (30) business days after an invoice is
received from Grantor by Purchaser. In the event the Purchaser has a dispute, in
respect of payment(s), and such dispute is of a reasonable, good faith,
commercial and uncapricious nature, the Purchaser shall be entitled to withhold
such payment(s) until the dispute is resolved. The Purchaser shall, however, be
obliged to use best efforts to assist in resolving such dispute referred to in
this Section 5(a).

     (b) Any invoice rendered under this Agreement which is not paid when due,
shall accrue interest at the annual rate of six percent (6%) above the rate for
U.S. dollar LIBOR for one month as quoted in The Wall Street Journal on the
                                             -----------------------
first business day of the month in which such payment is due. Such interest
shall accrue from the day following the date payment was due until it is paid in
full. In the event that applicable law does not allow the imposition of "default
interest" at the rate established in accordance with this Section 5(b), such
"default interest" shall be at the highest rate permitted by applicable law. For
purposes of this Section, "paid" shall mean that funds are available for
immediate use by Grantor.

                                                                               6


     6. DEFAULT. (a) Subject to Section 5(a) hereof, if the Purchaser fails to
     ----------
make any payment required by this Agreement on the date that it is due or if the
Purchaser is otherwise in breach of this Agreement, and such payment default
continues unremedied for a period of at least five (5) days or such other breach
continues for a period of at least thirty (30) days, Grantor or its authorized
agent may notify the Purchaser in writing of such payment default or other
breach and if full payment is not received or such other breach is not fully
remedied within fifteen (15) days of such notification, Grantor (i) may suspend
all service provided to Purchaser hereunder (including suspending Purchaser's
right to use the Inland Capacity), until such payment default or other breach
has been cured (including payment of default interest, if any) and (ii) shall be
entitled to pursue any and all rights and legal and equitable remedies
(including its rights and remedies to enforce the Purchaser's obligations under
this Agreement).

     (b) If the Grantor is in breach of this Agreement and such breach continues
for a period of at least thirty (30) days, the Purchaser may notify the Grantor
in writing of such breach and if such breach is not fully remedied within
fifteen (15) days of such notification, the Purchaser shall be entitled to
pursue any and all rights and legal and equitable remedies, including its rights
and remedies to enforce Grantor's obligations under this Agreement and further
including the right to terminate this Agreement and receive a pro-rata refund of
the Purchase Price based upon the remaining term. The Purchaser's right to
pursue any and all rights and legal and equitable remedies shall continue for so
long as such breach continues, provided, however, that a subsequent cure of any
such breach by Grantor shall not prejudice (i) any right or remedy properly
exercised by the Purchaser prior to the time such cure has been effected, or
(ii) the Purchaser's right to claim damages with respect to the period prior to
the time such cure has been effected.

     7. USE OF CAPACITY. (a) The use of the Inland Capacity granted hereunder
     ------------------
and any equipment associated therewith shall be such as not to interrupt,
interfere with, or impair service over any of the facilities comprising the
System or the Inland Capacity, or impair privacy of any communications over such
facilities, cause damage to plant or create hazards to employees, affiliates or
connecting companies of ACL, the Grantor, any Backhaul Provider or any other
user, owner or operator of the System or the Inland Capacity or the public. The
Purchaser shall bear the cost of any additional protective apparatus reasonably
required to be installed because of the use of such facilities by the Purchaser,
any lessees or permitted transferees of the Purchaser, or any customer or
customers of the Purchaser or of any such lessee or transferee, provided,
however, that this Section 7(a) shall only apply to the extent that such use is
outside the ordinarily anticipated use of such facilities. The Grantor will
cause all other purchasers of capacity in Inland Capacity provided hereunder to
undertake obligations comparable to those of the Purchaser set forth in this
Section, and the Purchaser shall cause all permitted users of the IRU in the
Inland Capacity granted hereunder to undertake comparable obligations.

otherwise) shall not relieve the Purchaser from any liabilities arising prior to
such termination.

     9. APPROVALS; LICENSES. The performance of this Agreement by each party
     ----------------------

hereunder and as may be satisfactory to it. The parties shall use reasonable
efforts to obtain and continue, and to have continued, such approvals, consents,
licenses and permits. No license under patents is granted by Grantor or shall be
implied or arise by estoppel in the Purchaser's favor with respect to any
apparatus, system or method used by the Purchaser in connection with the use of
the Inland Capacity granted to it hereunder.

     10. DISCLAIMER. (a) Grantor has entered into Backhaul Agreements to obtain
     --------------
plant, equipment and services necessary to allow the Inland Capacity to be

INCLUDING BUT NOT LIMITED TO, THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
A PARTICULAR PURPOSE ARE SPECIFICALLY DISCLAIMED.

     (b) The Purchaser has entered into the Capacity Purchase Agreement with ACL

not be deemed to be an event beyond the reasonable control of such party for the
purposes of this Section 11.

          collateral assignment of its rights hereunder to one or more lenders
          to the Purchaser or its affiliates, and (ii) to any present or future

          performance of its obligations hereunder to the extent the assignee
          fails to perform such obligations.

     (d)  (i) The Purchaser may enter into one or more agreements to lease or
          license the right to use any Purchased Capacity, so long as all such
          leases or licenses with any particular lessee or licensee (including
          all affiliates thereof) involve in the aggregate less than one (1) MCU
          of Purchased Capacity;

          (ii) The Purchaser may transfer a right to use any Purchased Capacity
          to a Carrier Party, so long as all such transfers to any particular
          transferee (including all affiliates thereof) involve in the aggregate
          less than one MCU of Purchased Capacity;

          (iii) Purchaser may not enter into any arrangements to lease, license
          or transfer a right to use an aggregate (in any combination of such
          arrangements) of one or more MCUs of Purchased Capacity to any
          particular lessee, licensee or transferee (including all affiliates
          thereof).

          (iv) No lease, license or transfer permitted by this Section 16(d)
          shall involve any delegation or other transfer of any of Purchaser's
          obligations or liabilities hereunder. Each lessee, licensee and
          transferee of any right to use Purchased Capacity shall derive all of
          its rights solely through the Purchaser and such rights shall be
          enforceable solely against the Purchaser. No such lessee, licensee or
          transferee shall become a third party beneficiary of this Agreement or
          obtain any right, title or interest in, to or under this Agreement or
          the Subsidiary IRU Agreement or the ability to enforce any provision
          hereof or thereof nor shall any thereof have any rights or claims
          against the Grantor for any reason whatsoever. The rights of any
          lessee, licensee or transferee of a right to use any Purchased
          Capacity shall be subject and subordinate to all the terms of this
          Agreement (including the Grantor's right to suspend service in the
          event of a default by Purchaser hereunder) and Purchaser shall remain
          primarily liable hereunder for the performance of all the terms of
          this Agreement to the same extent as if such lease, license or
          transfer had not occurred. Any such lease, license or transfer
          agreement shall prohibit further assignment, transfer or other
          disposition of Purchased Capacity except in accordance with the terms
          of this Section 16.

     (e)  The Grantor will cause to be maintained a Customer Care Center to
          provide service to the Purchaser and other users of the System. Only
          Carrier Parties which have acquired and hold the right to use one or
          more whole MCUs of Capacity shall be entitled to utilize the services
          of the Customer Care Center. Every entity which has the right to use
          one or

for or on account of any Taxes from any payment due hereunder to Grantor, then,

amount payable by the Purchaser to Grantor will be increased so that, after any
such deduction or withholding for Taxes, the net amount received by Grantor will

     (a) Except as otherwise set forth in this Agreement, the Purchaser shall
not be required to make any additional payments for costs associated with
operating, maintaining and repairing the Inland Capacity in which an IRU has

     (b) Grantor shall use reasonable commercial efforts to cause the Inland
Capacity in which an IRU has been granted hereunder to be maintained in
efficient working order and in accordance with industry standards and, to the
extent applicable, the Maintenance Performance Standards set forth in Schedule
IV to the Capacity Purchase Agreement which Schedule IV is incorporated herein
by reference. Grantor represents that at all times it shall use commercially
reasonable efforts to require the applicable Backhaul Provider with which it has
contracted to provide routine, preventive and corrective maintenance for the
Inland Capacity in accordance with performance standards that at least meet
prudent industry standards. Grantor will use reasonable commercial efforts to
cause the Backhaul Provider with which it has contracted to perform its
obligations under the applicable Backhaul Agreement.

     (c) Grantor will have sole responsibility for negotiating, executing and
administering contracts related to the acquisition of rights in any Inland
Capacity from Backhaul Providers.

     (d) Should any condition exist in any Inland Capacity in which an IRU has
been granted hereunder that may impair the integrity of such Inland Capacity,
Grantor shall take reasonable actions to cause to be initiated maintenance on
such Inland Capacity and Grantor shall take reasonable actions to cause to be
initiated planned maintenance on such Inland Capacity in each case which may
include the deactivation of such Inland Capacity. Grantor shall, to the extent
reasonably practicable, advise the Purchaser in writing at least thirty (30)
days (or such shorter period as may be agreed) prior to the initiation of a
planned maintenance operation of the timing and scope of such planned
maintenance operation.

     (e) In addition to fulfilling its obligations as set forth in Section 4(b),
in the event of disruption of service, Grantor shall use commercially reasonable
efforts to cause service to be

                                                                               5

as are reasonably necessary to obtain such objective.

     -----------------------------      --------
agent shall render invoices under this Agreement in Dollars, and the Purchaser
shall pay such amount in Dollars. The Purchaser shall make all payments by means
of a wire transfer to the Grantor's Account. Any payments required to be made
pursuant to this Agreement shall, save for the Initial Payment which shall be
made in accordance with the provisions of Section 3(b), be made on the later of
(i) the date when due or (ii) thirty (30) business days after an invoice is
received from Grantor by Purchaser. In the event the Purchaser has a dispute, in
respect of payment(s), and such dispute is of a reasonable, good faith,
commercial and uncapricious nature, the Purchaser shall be entitled to withhold
such payment(s) until the dispute is resolved. The Purchaser shall, however, be
obliged to use best efforts to assist in resolving such dispute referred to in
this Section 5(a).

     (b) Any invoice rendered under this Agreement which is not paid when due,
shall accrue interest at the annual rate of six percent (6%) above the rate for
U.S. dollar LIBOR for one month as quoted in The Wall Street Journal on the
                                             -----------------------
first business day of the month in which such payment is due. Such interest
shall accrue from the day following the date payment was due until it is paid in
full. In the event that applicable law does not allow the imposition of "default
interest" at the rate established in accordance with this Section 5(b), such
"default interest" shall be at the highest rate permitted by applicable law. For
purposes of this Section, "paid" shall mean that funds are available for
immediate use by Grantor.

     6. DEFAULT. (a) Subject to Section 5(a) hereof, if the Purchaser fails to
     ----------
make any payment required by this Agreement on the date that it is due or if the
Purchaser is otherwise in breach of this Agreement, and such payment default
continues unremedied for a period of at least five (5) days or such other breach
continues for a period of at least thirty (30) days, Grantor or its authorized
agent may notify the Purchaser in writing of such payment default or other
breach and if full payment is not received or such other breach is not fully
remedied within fifteen (15) days of such notification, Grantor (i) may suspend
all service provided to Purchaser hereunder (including suspending Purchaser's
right to use the Inland Capacity), until such payment default or other breach
has been cured (including payment of default interest, if any) and (ii) shall be
entitled to pursue any and all rights and legal and equitable remedies
(including its rights and remedies to enforce the Purchaser's obligations under
this Agreement).

     (b) If the Grantor is in breach of this Agreement and such breach continues
for a period of at least thirty (30) days, the Purchaser may notify the Grantor
in writing of such breach and if such breach is not fully remedied within
fifteen (15) days of such notification, the Purchaser shall be entitled to
pursue any and all rights and legal and equitable remedies, including its rights
and remedies to enforce Grantor's obligations under this Agreement and further
including the right to terminate this Agreement and receive a pro-rata refund of
the Purchase Price based upon the remaining term. The Purchaser's right to
pursue any and all rights and legal and equitable remedies shall continue for so
long as such breach continues, provided, however, that a subsequent cure of any
such breach by Grantor shall not prejudice (i) any right or remedy properly
exercised by the Purchaser prior to the time such cure has been effected, or
(ii) the Purchaser's right to claim
<PAGE>

                                                                               6

damages with respect to the period prior to the time such cure has been
effected.

     7. USE OF CAPACITY. (a) The use of the Inland Capacity granted hereunder
     ------------------
and any equipment associated therewith shall be such as not to interrupt,
interfere with, or impair service over any of the facilities comprising the
System or the Inland Capacity, or impair privacy of any communications over such
facilities, cause damage to plant or create hazards to employees, affiliates or
connecting companies of ACL, the Grantor, any Backhaul Provider or any other
user, owner or operator of the System or the Inland Capacity or the public. The
Purchaser shall bear the cost of any additional protective apparatus reasonably
required to be installed because of the use of such facilities by the Purchaser,
any lessees or permitted transferees of the Purchaser, or any customer or
customers of the Purchaser or of any such lessee or transferee, provided,
however, that this Section 7(a) shall only apply to the extent that such use is
outside the ordinarily anticipated use of such facilities. The Grantor will
cause all other purchasers of capacity in Inland Capacity provided hereunder to
undertake obligations comparable to those of the Purchaser set forth in this
Section, and the Purchaser shall cause all permitted users of the IRU in the
Inland Capacity granted hereunder to undertake comparable obligations.

     (b)  The IRU in the Inland Capacity granted hereunder shall be made
available to Grantor or the Backhaul Providers (or any of their subsidiaries or
agents), Iat such times agreeable to the Purchaser and Grantor or the Backhaul
Providers, as the case may be, to permit Grantor or the Backhaul Providers to
conduct such tests and adjustments as may be necessary for such capacity to be
maintained in efficient working order.

     8. DURATION OF AGREEMENT. (a) This Agreement shall become effective on the
     ------------------------
day and year set forth in the preamble hereto and shall continue in operation
until the twenty-fifth (25th) anniversary of the RFS Date for the System (the
"Term").
 ----

     (b) The termination of this Agreement (whether under this Section or
otherwise) shall not relieve the Purchaser from any liabilities arising prior to
such termination.

     9. APPROVALS; LICENSES. The performance of this Agreement by each party
     ----------------------
hereto is contingent upon the obtaining and the continuance of such approvals,
consents, governmental authorizations, licenses and permits as may be required
or reasonably deemed necessary by such party for performance by such party
hereunder and as may be satisfactory to it. The parties shall use reasonable
efforts to obtain and continue, and to have continued, such approvals, consents,
licenses and permits. No license under patents is granted by Grantor or shall be
implied or arise by estoppel in the Purchaser's favor with respect to any
apparatus, system or method used by the Purchaser in connection with the use of
the Inland Capacity granted to it hereunder.

     10. DISCLAIMER. (a) Grantor has entered into Backhaul Agreements to obtain
     --------------
plant, equipment and services necessary to allow the Inland Capacity to be
placed into operation on the applicable scheduled RFS Date. UNLESS SPECIFICALLY
SET FORTH IN THIS AGREEMENT, ANY OTHER WARRANTIES, EXPRESSED OR IMPLIED,
INCLUDING BUT NOT LIMITED TO, THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
A PARTICULAR PURPOSE ARE SPECIFICALLY DISCLAIMED.

                                                                               7

     (b) The Purchaser has entered into the Capacity Purchase Agreement with ACL
in order to acquire an IRU in certain capacity on the System. The Purchaser
acknowledges and agrees that Grantor does not warrant or guarantee the
performance of the Capacity Purchase Agreement (or the Right of Use Agreement)
and shall have no liability with respect thereto.

     11. LIMITATIONS OF LIABILITY. (a) Except as otherwise provided in this
     ----------------------------
Agreement, in no event shall any party hereto be liable to the other for
consequential, incidental, indirect or special damages, including, but not
limited to, loss of revenue, loss of business opportunity or the costs
associated with the use of external restoration facilities, including, without
limitation, for any loss or damage sustained by reason of any failure in or
breakdown of any Inland Capacity or the facilities associated therewith, the
failure of any Backhaul Provider to perform the terms and conditions of any
Backhaul Agreement to which it is a party or for any interruption of service,
whatever the cause and however long it shall last.

     (b) Grantor shall not be liable to the Purchaser for any loss or damage
which may be suffered by the Purchaser by reason of any circumstances beyond the
control of Grantor and having an adverse effect on the provision of any part of
the Inland Capacity in which the Purchaser is entitled to capacity or has any
other right or interest under this Agreement. Failure by a subcontractor of any
of the parties to comply with its contractual commitments to such party shall
not be deemed to be an event beyond the reasonable control of such party for the
purposes of this Section 11.

     (c)(i) Grantor shall not be liable to the Purchaser for any loss or damage
which may be suffered by the Purchaser as a result of, related to, or in
connection with, the Purchaser's compliance or non-compliance with any
applicable state, federal, foreign governmental, international (foreign or
domestic) or other law related to the transfer of the IRU in, or the use of, the
Inland Capacity granted hereunder.

     (ii) The Purchaser shall not be liable to Grantor for any loss or damage
which may be suffered by Grantor as a result of, related to, or in connection
with, Grantor's non-compliance with any applicable state, federal, foreign
governmental, international (foreign or domestic) or other law related to the
transfer by Grantor of the IRU to the Purchaser in, or Grantor's operation,
ownership or use of, the Inland Capacity.

     12. EXPORT CONTROL. The parties hereto acknowledge that to the extent any
     ------------------
products, software or technical information provided under this Agreement are or
may be subject to any applicable export laws and regulations, the parties hereto
agree that they will not use, distribute, transfer or transmit the products,
software or technical information (even if incorporated into other products)
except in compliance with such export laws and regulations (or licenses or
orders issued pursuant thereto). If requested by either party hereto the other
party agrees to sign all necessary export-related documents as may be required
to comply therewith.

     13. REPRESENTATIONS; INDEMNITY. (a) Grantor hereby represents and warrants
     ------------------------------

necessary corporate action on the part of Grantor and this Agreement is a valid,
binding and enforceable obligation of Grantor enforceable in accordance with its

organizational documents or any order, decree or judgment of any court, tribunal

laws of its jurisdiction of organization; (ii) the execution, delivery and

has obtained all approvals, consents, governmental authorizations, licenses and
permits as may be required to enter into this Agreement, and grant or acquire,
as the case may be, the IRU in the Inland Capacity and otherwise to perform its
obligations hereunder.

     (d) The foregoing representations and warranties shall survive the
execution and delivery of this Agreement.

     (e) Subject to Section 11, the Purchaser agrees to indemnify and hold
harmless Grantor and its officers, directors, employees, agents,
representatives, successors and assigns (each, an "indemnitee") from and against
any loss, damage, expense or cost arising out of or in connection with (i) any
breach or violation by the Purchaser of applicable law or governmental
regulation, and (ii) any claims of whatever nature by third parties with respect

permitted user of the Inland Capacity) with any remedy, claim, liability,
reimbursement, cause of action, or any other right, except for assignees
pursuant to an assignment which is permitted under Section 16 of this Agreement.
Furthermore, the Purchaser acknowledges that it is not a third party beneficiary
of any agreement entered into by Grantor including, but not limited to, the
Backhaul Agreements.
<PAGE>

     16.  ASSIGNMENT.
     ---------------

     binding on the "Grantor" hereunder and shall not be permitted to assign,
     transfer or otherwise dispose of any or all of its right, title or interest
     hereunder or delegate any or all of its obligations hereunder to any person
     or entity except that the Grantor and the Subsidiary Grantors shall be
               ------
     permitted to (i) effect a collateral assignment of their respective rights
     hereunder to one or more lenders to Grantor or its affiliates and (ii)
     assign, transfer or otherwise dispose of any or all of their rights
     hereunder and under the Subsidiary IRU Agreement and delegate any or all of
     their obligations hereunder and under the Subsidiary IRU Agreement to any
     present or future affiliated company of the Grantor or to an entity
     controlled by, under the same control as, or controlling, the Grantor. The
     Grantor shall give the Purchaser notice of any such assignment, transfer or
     other disposition or any such delegation.

(c)  The Purchaser shall solely be responsible for complying with all of the
     terms binding on the "Purchaser" hereunder and shall not be permitted to
     assign, transfer or otherwise dispose of any or all of its right, title or
     interest hereunder or under the Subsidiary IRU Agreement (except for
     leases, licenses and transfers of the right to use Capacity to the extent
     set forth in Section 16(d) below) or delegate any or all of its obligations
     hereunder or under the Subsidiary IRU Agreement to any person or entity
     except (i) a collateral assignment of its rights hereunder to one or more
     lenders to the Purchaser or its affiliates, and (ii) to any present or
     future affiliated company of the Purchaser or to an entity controlled by,
     under the same control as, or controlling, the Purchaser; and (iii)
     incident to the transfer of all or substantially all of its business or a
     substantial portion of its business (which shall include, without
     limitation, a transfer of assets); provided, however, that the Purchaser
                                        --------
     shall remain responsible for the performance of its obligations hereunder
     to the extent the assignee fails to perform such obligations.

(d)  (i)  The Purchaser may enter into one or more agreements to lease or
     license the right to use any Purchased Capacity, so long as all such leases
     or licenses with any particular lessee or licensee (including all
     affiliates thereof) involve in the aggregate less than one (1) MCU of
     Purchased Capacity;

     (ii) The Purchaser may transfer a right to use any Purchased Capacity to a
     Carrier Party, so long as all such transfers to any particular transferee
     (including all affiliates thereof) involve in the aggregate less than one

     MCUs of Purchased Capacity to any particular lessee, licensee or transferee
     (including all affiliates thereof).

     (iv) No lease, license or transfer permitted by this Section 16(d) shall
     involve any delegation or other transfer of any of Purchaser's obligations
     or liabilities hereunder. Each lessee, licensee and transferee of any right
     to use Purchased Capacity shall derive all of its rights solely through the
     Purchaser and such rights shall be enforceable solely against the
     Purchaser. No such lessee, licensee or transferee shall become a third
     party beneficiary of this Agreement or obtain any right, title or interest
     in, to or under this Agreement or the Subsidiary IRU Agreement or the
     ability to enforce any provision hereof or thereof nor shall any thereof
     have any rights or claims against the Grantor for any reason whatsoever.
     The rights of any lessee, licensee or transferee of a right to use any
     Purchased Capacity shall be subject and subordinate to all the terms of
     this Agreement (including the Grantor's right to suspend service in the
     event of a default by Purchaser hereunder) and Purchaser shall remain
     primarily liable hereunder for the performance of all the terms of this
     Agreement to the same extent as if such lease, license or transfer had not
     occurred. Any such lease, license or transfer agreement shall prohibit
     further assignment, transfer or other disposition of Purchased Capacity
     except in accordance with the terms of this Section 16.

(e)  The Grantor will cause to be maintained a Customer Care Center to provide
     service to the Purchaser and other users of the System. Only Carrier
     Parties which have acquired and hold the right to use one or more whole
     MCUs of Capacity shall be entitled to utilize the services of the Customer
     Care Center. Every entity which has the right to use one or more MCUs of
     Capacity shall promptly contact the Customer Care Center and provide all
     such information reasonably requested by the Customer Care Center.

(f)  Any assignment, transfer or other disposition by either Party which is in
     violation of this Section shall be void and of no force and effect.

     17. CONDITION TO PURCHASER'S OBLIGATIONS. The Purchaser's obligation to pay
     ----------------------------------------

Capacity on any Segment other than Segment S-1 (for which the RFS Date has
already occurred) shall terminate if the RFS Date for such Purchased Capacity
has not occurred by June 30, 1999. In any such event, the Purchaser may
terminate this Agreement in its entirety and receive a complete refund of all
amounts paid hereunder or the Purchaser may terminate this Agreement only with
respect to such Inland Capacity in which case Grantor shall refund all amounts
paid by the Purchaser, if any, with respect to such Inland Capacity as to which
Purchaser's obligation has terminated within thirty (30) days after the
applicable date.

     18. NOTICES. Each notice, demand, certification or other communication
     -----------
given or made under this Agreement shall be in writing and shall be delivered by
hand or sent by registered mail or by facsimile transmission to the address of

other party hereto in accordance with the terms of this Section). Any change to

postal notice.

transferee or lessee of all or part of its rights hereunder provided that such
actual or proposed assignee agrees in writing to be bound by the provisions of
this Section 20.

     (b) The foregoing shall not restrict either party from publicly announcing
that it has entered into this Agreement with the parties hereto, but without
including any details contained in this Agreement.

3.   PAYMENT FOR CAPACITY.
     --------------------

     (a)   Financing. Grantor shall finance the Purchase Price for the Purchased
           ---------
           Capacity in accordance with Schedule II hereto. Payments by Purchaser
           shall (i) be calculated to pay Grantor interest calculated at the
           rate set out therein, (ii) be pre-payable, in whole or in part,
           without penalty, and (iii) be secured by Grantor retaining a security
           interest in the IRU until the Purchase Price is fully paid. Each of
           the parties shall, at its expense, take all such actions and make all
           such filings and recordings as are reasonably requested to establish,
           perfect and protect the other party's interest in such IRU.

           --------------------------
           at the request of the Grantor, additional payments in respect of the
           right of use granted under this Agreement, or the Right of Use
           Agreement, for access connection rearrangement requested by the
           Purchaser as set forth in Schedule III to this Agreement and such
           other reasonable costs in respect of additional services or equipment

           shall mutually agree.

                                       5
<PAGE>

     (d)   Taxes. All payments made by the Purchaser under this Section 3 shall
           -----
           be made without any deduction or withholding for or on account of any
           tax, duty or other charges of whatever nature imposed by any taxing
           or governmental authority in the jurisdiction from which payment by
           the Purchaser originates or in any other jurisdiction claiming the
           right to impose such tax, duty or charge due to the location of any
           business or properties of the Purchaser (collectively "Taxes"). If
           the Purchaser is or was required by law to make any deduction or
           withholding for or on account of any Taxes from any payment due
           hereunder to the Grantor (for the benefit of the Grantor and the
           benefit of the Subsidiary Grantors ), then, notwithstanding anything
           to the contrary contained in this Agreement, the gross amount payable
           by the Purchaser to the Grantor (for the benefit of the Grantor and
           the benefit of the Subsidiary Grantors) will be increased so that,
           after any such deduction or withholding for Taxes, the net amount
           received by the Grantor (for the benefit of the Grantor and the
           benefit of the Subsidiary Grantors) will not be less than the Grantor
           (for the benefit of the Grantor and the benefit of the Subsidiary
           Grantors) would have received had no such deduction or withholding
           been required. If any taxing or government authority asserts that the
           Purchaser should have made a deduction or withholding for on account
           of any Taxes with respect to all or a portion of any payment made
           hereunder, the Purchaser hereby agrees to indemnify the Grantor for
           such Taxes and hold the Grantor harmless on an after-tax basis from
           and against any Taxes, interest or penalties levied or asserted in
           connection therewith.

           are based on its allocated share of the costs for operating,
           maintaining and repairing the System in accordance with and subject
           to the limitations set forth in Paragraph 8 of Annex B. Maintenance
           Costs shall be payable quarterly in advance on each January 1, April
           1, July 1 and October 1, commencing with the first January 1 after
           the applicable Payment Due Date, except that on the applicable
           Payment Due Date for the Purchased Capacity the Purchaser shall make
           a proportional payment for the period (the "Stub Period") from the
           applicable Payment Due Date to the first January 1 thereafter.

     (b)   Maintenance. (i) The Grantor shall use reasonable commercial efforts
           -----------
           to cause the System to be maintained in efficient working order and
           in accordance with industry standards and the Maintenance Performance
           Standards set forth in Schedule IV to this Agreement which is
           incorporated herein by reference. The Grantor represents that (A) the
           OA&M Agreement (the "OA&M Agreement") is in full force and effect and
           that neither the Grantor nor, to the best of the Grantor's knowledge,
           any other

                                       6
<PAGE>

           party to the OA&M Agreement is in material default of any provision
           thereof; (B) that the OA&M Agreement requires and at all times the
           Grantor shall require TSSL to provide routine, preventive and
           corrective maintenance for the System in accordance with performance
           standards that at least meet prudent industry standards; and (C) the
           Grantor shall maintain the OA&M Agreement in full force and effect
           and will use reasonable commercial efforts to cause TSSL to perform
           its obligations under the OA&M Agreement and the Supply Contract.

           (ii)  The Grantor together with the Subsidiary Grantors will have
                 sole responsibility for negotiating, executing and
                 administering contracts and all other aspects related to the
                 construction, operation, maintenance and repair of the System.

           (iii) Should any condition exist in any Segment that may impair the
                 integrity of the System, the Grantor shall initiate and
                 coordinate planned maintenance (or shall cause such action to
                 occur), on such relevant Segment which may include the
                 deactivation of such Segment. The Grantor shall, to the extent
                 reasonably practicable, advise the Purchaser in writing at
                 least sixty (60) days (or such shorter period as may be
                 necessary), prior to initiating a planned maintenance
                 operation, of the timing, scope and costs of such planned
                 maintenance operation.

           (iv)  In addition to fulfilling its obligations as set forth in
                 Section 4(b)(i), in the event of disruption of service due to
                 force majeure or other emergency, the Grantor shall cause
                 service to be restored as quickly as reasonably possible, and
                 the Grantor shall take such measures as are reasonably
                 necessary to obtain such objective.

           (v)   In addition to fulfilling its obligations as set forth in
                 Section 4(b)(i), the Grantor shall provide the Customer Care
                 Center services as described in Schedule V to this Agreement,
                 which is incorporated by reference herein.

           (vi)  In fulfilling its obligations as set forth in Section 4(b)(i),
                 the Grantor shall not provide any preference for the repair of
                 its or any other party's facilities, but rather shall perform
                 such services in a manner that does not discriminate against
                 the Purchaser.

5.   INVOICES; DEFAULT INTEREST.
     --------------------------

     (a)   Invoices. The Grantor (and/or the Subsidiary Grantors) or its
           --------
           authorized agent (which may include the Operator), shall render
           invoices under this Agreement in Dollars, and the Purchaser shall pay
           such amount in Dollars. The Purchaser shall make all payments by
           means of a wire transfer to Grantor's Account (for the benefit of the
           Grantor and the Subsidiary

                                       7
<PAGE>

           Grantors). Any payments required to be made pursuant to this
           Agreement shall be made on the later of (i) the date when due or (ii)
           thirty (30) business days after an invoice is received from Grantor
           by Purchaser. In the event the Purchaser has a dispute, in respect of
           payment(s), and such dispute is of a reasonable, good faith,
           commercial and uncapricious nature, the Purchaser shall be entitled
           to withhold such payment(s) until the dispute is resolved. The
           Purchaser shall, however, be obliged to use best efforts to assist in
           resolving such dispute referred to in this Section 5(a).

     (b)   Default Interest. Any invoice rendered under this Agreement which is
           ----------------
           not paid when due, shall accrue interest at the annual rate of six
           percent (6%) above the rate for U.S. dollar LIBOR for one month as
           quoted in The Wall Street Journal on the first business day of the
                     -----------------------
           month in which such payment is due. Such interest shall accrue from
           the day following the date payment was due until it is paid in full.
           In the event that applicable law does not allow the imposition of
           "default interest" at the rate established in accordance with this
           Section 5(b), such "default interest" shall be at the highest rate
           permitted by applicable law. For purposes of this Section, "paid"
           shall mean that funds are available for immediate use by the Grantor.

6.   DEFAULT
     -------

     (a)   Subject to Section 5(a) hereof, if the Purchaser fails to make any
           payment required by this Agreement on the date that it is due, or if
           the Purchaser is otherwise in breach of this Agreement, and such
           payment default continues unremedied for a period of at least five
           (5) days or such other breach continues for a period of at least
           thirty (30) days, the Grantor, or its authorized agent, may notify
           the Purchaser in writing of such payment default or other breach and
           if full payment is not received or such other breach is not fully
           remedied within fifteen (15) days of such notification, the Grantor:
           (i) may suspend all service provided to Purchaser hereunder and under
           the Right of Use Agreement (including suspending Purchaser's right to
           use the Purchased Capacity), until such payment default or other
           breach has been cured (including payment of default interest, if any)
           and (ii) shall be entitled to pursue any and all rights and legal and
           equitable remedies (including its rights and remedies to enforce the
           Purchaser's obligations under this Agreement).

     (b)   If the Grantor is in breach of this Agreement and such breach
           continues for a period of at least thirty (30) days, the Purchaser
           may notify the Grantor in writing of such breach and if such breach
           is not fully remedied within fifteen (15) days of such notification,
           the Purchaser shall, for so long as such breach continues, be
           entitled to pursue any and all rights and legal and equitable
           remedies, including its rights and remedies to enforce Grantor's
           obligations under this Agreement and further including the right to
           terminate this Agreement and receive a pro-rata refund of the
           Purchase

                                       8
<PAGE>

           Price based upon the remaining term. The Purchaser's right to pursue
           any and all rights and legal and equitable remedies shall continue
           for so long as such breach continues, provided, however, that a
           subsequent cure of any such breach by Grantor shall not prejudice (i)
           any right or remedy properly exercised by the Purchaser prior to the
           time such cure has been effected, or (ii) the Purchaser's right to
           claim damages with respect to the period prior to the time such cure
           has been effected.

7.   USE OF CAPACITY.
     ---------------

     (a)   The operation of the Purchased Capacity and any equipment associated
           therewith shall be such as not to interrupt, interfere with, or
           impair service over any of the facilities comprising the System, or
           impair privacy of any communications over such facilities, cause
           damage to plant or create hazards to employees, affiliates or
           connecting companies of the Grantor, any Subsidiary Grantor, the
           Purchaser, or any other user, owner or operator of the System or the
           public. The Purchaser shall bear the cost of any additional
           protective apparatus reasonably required to be installed because of
           the use of such facilities by the Purchaser, any lessees or permitted
           transferees of the Purchaser, or any customer or customers of the
           Purchaser or of any such lessee or transferee provided, however, that
           this Section 7(a) shall only apply to the extent that such use is
           outside the ordinarily anticipated use of such facilities. The
           Grantor will cause all other purchasers of capacity in the System to
           undertake obligations comparable to those of the Purchaser set forth
           in this Section, and the Purchaser shall cause all permitted users of
           the IRU in the Purchased Capacity to undertake comparable
           obligations.

     (b)   The Purchased Capacity granted to the Purchaser shall be made
           available to the Grantor (or its subsidiaries, its agents or the
           Operator), at such times agreeable to the Purchaser and the Grantor,
           to permit the Grantor and the Subsidiary Grantors to conduct such
           tests and adjustments as may be necessary for such capacity to be
           maintained in efficient working order.

8.   DURATION OF AGREEMENT.
     ---------------------

     (a)   This Agreement shall become effective on the day and year set forth
           in the preamble hereto and shall continue in operation until the
           twenty-fifth (25th) anniversary of the RFS Date for the System.

     (b)   The termination of this Agreement (whether under this Section or
           otherwise) shall not relieve either party from any liabilities
           arising prior to such termination.

     (c)   Upon the termination of this Agreement, so long as Purchaser is not
           in default hereunder, the Purchaser may elect to extend its rights in
           the System, for so long as the System exists or has not been retired,
           by giving written notice to Grantor and paying to Grantor one (1)
           Dollar. Such election to extend shall not affect or delay the
           termination of the Grantor's

                                       9
<PAGE>

          obligations under this Agreement. Upon such election to extend and
          payment, the Purchaser, together with all other purchasers of capacity
          on the System that also elect to so extend, shall become the sole
          owners of the System. The ownership interests of the Purchaser and
          such other purchasers shall be in proportion to the amount of capacity
          covered by IRU's previously granted to the Purchaser and such other
          purchasers. The Grantor shall execute and deliver such documentation
          as may be reasonably required to effect such transfer of ownership.
          Without limitation to the generality of the foregoing provisions,
          Grantor shall have no obligation to operate or maintain the System
          during such extension.

     (d)  The parties hereto shall discuss with each other and the other
          purchasers of capacity on the System establishing a procedure for the
          early retirement of the System if such retirement appears to be
          commercially appropriate.

9.   APPROVALS; LICENSES.
     -------------------

     The performance of this Agreement by each party hereto is contingent upon
     the obtaining and continuance of such approvals, consents, governmental
     authorizations, licenses and permits as may be required or reasonably
     deemed necessary by such party for performance by such party hereunder and
     as may be satisfactory to it. The parties shall use (and in the case of the
     Grantor, shall cause the Subsidiary Grantors to use) reasonable efforts to
     obtain and continue, and to have continued, such approvals, consents,
     licenses and permits. No license under patents is granted by the Grantor or
     any of the Subsidiary Grantors or shall be implied or arise by estoppel in
     the Purchaser's favor with respect to any apparatus, system or method used
     by the Purchaser in connection with the use of the capacity granted to it
     hereunder or under the Right of Use Agreement.

10.  DISCLAIMER.
     ----------

     (a)  The Grantor and the Subsidiary Grantors have entered into the Supply
          Contract to obtain plant, equipment and services necessary to allow
          the Purchased Capacity to be placed into operation on the applicable
          scheduled RFS Date. UNLESS SPECIFICALLY SET FORTH IN THIS AGREEMENT,
          ANY OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING BUT NOT LIMITED
          TO, THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
          PURPOSE ARE SPECIFICALLY DISCLAIMED.

     (b)  In order to make it more convenient for the Purchaser to connect the
          Purchased Capacity to inland networks, the Grantor and the Subsidiary
          Grantors have permitted certain Inland Carriers to collocate at the
          cable stations located at each T Segment. Neither the Grantor, any
          Subsidiary Grantor or any of their respective affiliates warrants or
          guarantees any agreement between the Purchaser and any Inland Carrier
          and neither the Grantor, any Subsidiary Grantor or any of their
          respective affiliates shall

                                      10
<PAGE>

          have any liability to the Purchaser for any failure of any Inland
          Carrier to perform the terms and conditions of any such agreement.

11.  LIMITATIONS OF LIABILITY.
     ------------------------

     (a)  Except as otherwise provided in this Agreement or in the Right of Use
          Agreement, in no event shall the Purchaser, the Grantor or any
          Subsidiary Grantor be liable to the other for consequential,
          incidental, indirect or special damages, including, but not limited
          to, loss of revenue, loss of business opportunity, or the costs
          associated with the use of external restoration facilities, including,
          without limitation, for any loss or damage sustained by reason of any
          failure in or breakdown of the System or the facilities associated
          with the System, the failure of any Inland Carrier to perform the
          terms and conditions of any agreement to which it and the Purchaser
          are parties or for any interruption of service, whatever the cause and
          however long it shall last.

     (b)  Neither the Grantor nor any Subsidiary Grantor shall be liable to the
          Purchaser for any loss or damage which may be suffered by the
          Purchaser by reason of any circumstances beyond the control of the
          Grantor and the Subsidiary Grantors and having an adverse effect on
          the provision of any part of the System in which the Purchaser is
          entitled to capacity or has any other right or interest under this
          Agreement or under the Right of Use Agreement. Failure by a
          subcontractor of any of the parties to comply with its contractual
          commitments to such party shall not be deemed to be an event beyond
          the reasonable control of such party for the purposes of this Section
          11.

     (c)  (i) Neither the Grantor nor any Subsidiary Grantor shall be liable to
          the Purchaser for any loss or damage which may be suffered by the
          Purchaser as a result of, related to, or in connection with, the
          Purchaser's compliance or non-compliance with any applicable state,
          federal, foreign governmental, international (foreign or domestic) or
          other law related to the transfer of the IRU in, or the use of, the
          Purchased Capacity.

          (ii) The Purchaser shall not be liable to the Grantor or any
          Subsidiary Grantor for any loss or damage which may be suffered by
          Grantor or any Subsidiary Grantor as a result of, related to, or in
          connection with, Grantor's or Subsidiary Grantor's non-compliance with
          any applicable state, federal, foreign governmental, international
          (foreign or domestic) or other law related to the transfer by Grantor
          of the IRU to the Purchaser in, or Grantor's operation, ownership or
          use of, the System.

12.  SETTLEMENT OF DISPUTES.
     ----------------------

     (a)  The parties hereto shall endeavor to settle amicably by mutual
          discussions any disputes, differences, or claims whatsoever related to
          this Agreement.

     (b)  Failing such amicable settlement, any controversy, claim or dispute
          arising under or relating to this Agreement, including the existence,
          validity, interpretation, performance, termination or breach thereof,
          shall finally be settled by arbitration in accordance with the
          International Arbitration Rules of the American Arbitration
          Association ("AAA"). There shall be three (3) arbitrators (the
          "Arbitration Tribunal"), the first of which shall be appointed by the
          claimant in its notice of arbitration, the second of which shall be
          appointed by the respondent within thirty (30) days of the appointment
          of the first arbitrator and the third of which shall be jointly
          appointed by the party-appointed arbitrators within thirty (30) days
          thereafter. The language of the arbitration shall be English. The
          Arbitration Tribunal will not have authority to award punitive damages
          to either party. Each party shall bear its own expenses, but the
          parties shall share equally the expenses of the Arbitration Tribunal
          and the AAA. This Agreement shall be enforceable, and any arbitration
          award shall be final, and judgment thereon may be entered in any court
          of competent jurisdiction. The arbitration shall be held in New York,
          New York, USA.

13.  INCREASE OF INITIAL DESIGN CAPACITY.
     -----------------------------------

     The Grantor and the Subsidiary Grantors shall have authority to increase,
     at their own cost and expense, the Initial Design Capacity of the System.

14.  GOVERNING LAW.
     -------------

     This agreement shall be governed by and construed in accordance with the
     laws of the State of New York, United States of America without regard to
     the conflicts of laws rules of such State or any other jurisdiction that
     would apply the law of a different jurisdiction.

15.  WAIVER OF IMMUNITY.
     ------------------

     The parties hereto acknowledge that this Agreement is commercial in nature,
     and each party hereto expressly and irrevocably waives any claim or right
     which it may have to immunity (whether sovereign immunity, act of state or
     otherwise) for itself or with respect to any of its assets in connection
     with an arbitration, arbitral award or other proceeding to enforce this
     Agreement, including, without limitation, immunity from service of process,
     immunity of any of its assets from pre- or post-judgment attachment or
     execution and immunity from the jurisdiction of any court or arbitral
     tribunal.

     The parties hereto acknowledge that to the extent any products, software or
     technical information provided under this Agreement or the Right of Use
     Agreement are or may be subject to any applicable export laws and
     regulations, the parties hereto agree that they will not use, distribute,
     transfer or transmit the products, software or technical information (even
     if incorporated into other products) except in compliance with such export
     laws and regulations (or licenses or orders issued pursuant thereto). If

          Subsidiary IRU Agreement to any person or entity except (i) a
          collateral assignment of its rights hereunder to one or more lenders
          to the Purchaser or its affiliates, and (ii) to any present or future
          affiliated company of the Purchaser or to an entity controlled by,

          incident to the transfer of all or substantially all of its business

                                             --------
          Purchaser shall remain responsible for the performance of its

          obligations.

     (d)  (i) The Purchaser may enter into one or more agreements to lease or

          (iii) Purchaser may not enter into any arrangements to lease, license
          or transfer a right to use an aggregate (in any combination of such

          particular lessee, licensee or transferee (including all affiliates
          thereof).

<PAGE>

          (iv) No lease, license or transfer permitted by this Section 25(d)
          shall involve any delegation or other transfer of any of Purchaser's
          obligations or liabilities hereunder. Each lessee, licensee and
          transferee of any right to use Purchased Capacity shall derive all of
          its rights solely through the Purchaser and such rights shall be
          enforceable solely against the Purchaser. No such lessee, licensee or
          transferee shall become a third party beneficiary of this Agreement or
          obtain any right, title or interest in, to or under this Agreement or
          the Subsidiary IRU Agreement or the ability to enforce any provision
          hereof or thereof nor shall any thereof have any rights or claims
          against the Grantor for any reason whatsoever. The rights of any
          lessee, licensee or transferee of a right to use any Purchased
          Capacity shall be subject and subordinate to all the terms of this
          Agreement (including the Grantor's right to suspend service in the
          event of a default by Purchaser hereunder) and Purchaser shall remain
          primarily liable hereunder for the performance of all the terms of
          this Agreement to the same extent as if such lease, license or
          transfer had not occurred. Any such lease, license or transfer
          agreement shall prohibit further assignment, transfer or other
          disposition of Purchased Capacity except in accordance with the terms
          of this Section 25.

     (e)  The Grantor will cause to be maintained a Customer Care Center to
          provide service to the Purchaser and other users of the System. Only
          Carrier Parties which have acquired and hold the right to use one or
          more whole MCUs of Capacity shall be entitled to utilize the services
          of the Customer Care Center. Every entity which has the right to use
          one or more MCUs of Capacity shall promptly contact the Customer Care
          Center and provide all such information reasonably requested by the
          Customer Care Center.

     (f)  Any assignment, transfer or other disposition by either Party which is
          in violation of this Section shall be void and of no force and effect.

21.  CONDITION TO PURCHASER'S OBLIGATIONS.
     ------------------------------------

     The Purchaser's obligation to pay for an IRU with respect to any Purchased
     Capacity shall terminate if the RFS Date for such Purchased Capacity has
     not occurred by June 30, 1999. In any such event, the Purchaser may
     terminate this Agreement in its entirety and receive a complete refund of
     all amounts paid hereunder or the Purchaser may terminate this Agreement
     only with respect to such Purchased Capacity in which case the Grantor
     shall refund all amounts paid by the Purchaser, if any, with respect to
     such Purchased Capacity as to which Purchaser's obligation has terminated
     within thirty (30) days after the applicable date.

                             ADDENDUM TO AGREEMENTS
                               DATED JUNE 21, 1999
                                 BETWEEN EACH OF
                             ATLANTIC CROSSING LTD.,
                              GT LANDING CORP. AND
                                  GT U.K. LTD.
                                       AND
                        VIA NET WORKS EUROPE HOLDING B.V.

     This Addendum is made and entered into concurrently with (i) a Capacity
Purchase Agreement (the "CPA") of even date herewith by and between Atlantic
Crossing Ltd. ("Grantor") and VIA Net Works Europe Holding B.V. ("Purchaser"),
(ii) an Indefeasible Right of Use Agreement in Inland Capacity (United States)
(the "US Backhaul Agreement") of even date herewith by and between GT Landing
Corp. and Purchaser, and (iii) an Indefeasible Right of Use Agreement in Inland
Capacity (United Kingdom) (the "UK Backhaul Agreement") of even date herewith by
and between GT U.K. Ltd. and Purchaser. The CPA, the US Backhaul Agreement and
the UK Backhaul Agreement are referred to collectively as the "Agreements". If
there is any inconsistency between the terms and conditions of this Addendum and
the Agreements, the terms and conditions of this Addendum shall control.
Capitalized terms used in this Addendum without separate definition shall have
the meanings set forth in the Agreements.

     1. Interim Lease Arrangement. Notwithstanding anything in the Agreements to
        -------------------------
the contrary, Grantor hereby Leases on an interim basis the Purchased Capacity
to Purchaser in accordance with the terms and conditions of this Addendum (the
"Interim Lease"). This Interim Lease shall be in lieu of the transfer of an IRU
in the Purchased Capacity and the Inland Capacity as described in the
Agreements. This Interim Lease shall commence as of the Effective Date and shall
remain in effect for an initial term of six months (the "Initial Term"). In
consideration of the Purchased Capacity and the Inland Capacity to be provided
to Purchaser, Purchaser shall make Interim Lease payments of US [*****] per
quarter, payable on or before the first day of each quarter.

     2. Conversion to Purchase Agreement. Purchaser shall have the option to
        --------------------------------
convert the Interim Lease into a purchase of an IRU in the Purchased Capacity
and the Inland Capacity in accordance with the terms and conditions originally
set forth in the Agreements. Such option shall be exercisable in Purchaser's
sole discretion at any time during the Initial Term; provided, however, that
Purchaser shall be required to exercise such option within 15 days after
Purchaser receives such licenses as Purchaser requires in
<PAGE>

order to hold title to the IRU in the Purchased Capacity and the Inland Capacity
in Europe. Upon exercise of the option, Purchaser shall provide written notice
of exercise to Grantor, which notice shall be accompanied by payment of the
remaining portion of the down payment for the Purchased Capacity and the Inland
Capacity as set forth in Part B of Schedule II of the CPA. In determining the
remaining portion of the down payment for the Purchased Capacity and the Inland
Capacity, Purchaser shall receive full credit for any Interim Lease payments
made pursuant to this Addendum. Following the exercise of such conversion
option, Purchaser shall pay the remaining balance of the Purchase Price for the
Purchased Capacity and the Inland Capacity in accordance with the terms and
conditions originally set forth in the Agreements.

     3. Conversion to Three Year Lease. If Purchaser is unable to obtain such
        ------------------------------
licenses as Purchaser requires in order to hold title to the IRU in the
Purchased Capacity and the Inland Capacity in Europe and does not otherwise
Ichoose to exercise the purchase option described in Section 2 of this Addendum
during the Initial Term, the parties shall, effective as of the termination of
the Initial Term, convert the Interim Lease into a three year lease with
payments as agreed by the parties. To the extent reasonably possible, all other
terms applicable to the three year lease shall be the same as the terms set
forth in the Agreements. The parties shall cooperate with one another and shall
execute and deliver, or cause to be executed and delivered, all such documents
and instruments, in addition to those otherwise required by this Addendum, as
may be reasonably required to reflect such three year lease.

     4. OA&M Charges. OA&M charges on the System are not included in Interim
        ------------
Lease payments and shall be made separately during the Initial Term in
accordance with the CPA. If Purchaser is unable to convert the Interim Lease
into a purchase of the Purchased Capacity within the Initial Term and
subsequently enters into the three year lease, the OA&M charges will be credited
to the Purchaser against the next following three year lease payment(s).

     5. Exception to Purchaser Representations and Warranties. Grantor hereby
        -----------------------------------------------------
acknowledges that Purchaser has disclosed to Grantor that Purchaser is in the
process of obtaining the licenses it needs in order to hold title to the IRU in
the Purchased Capacity and the Inland Capacity in Europe and that the need to

<PAGE>

                                   SCHEDULE II

                           CAPACITY PURCHASE AGREEMENT

                                     Part A
                                     ------

     Notwithstanding anything to the contrary contained in the Capacity Purchase
Agreement to which this Schedule II is attached (as amended, supplemented or
otherwise modified from time to time, the "Capacity Purchase Agreement"):

     In exchange for the IRU interest granted pursuant to this Agreement and the
Right of Use Agreement in any Purchased Capacity, the Purchaser shall, on or
before (the "Initial Payment Due Date"), pay the Grantor (for the benefit of the
Grantor and the benefit of the Subsidiary Grantors), in immediately available
funds equal to an amount set out in the Payment Schedule attached hereto (the
"Initial Payment"). Thereafter, the Purchaser shall pay the remaining balance of
the Purchase Price for such Purchased Capacity quarterly, with the first such
payment being due on the date which is three months after such Initial Payment
Due Date and each remaining payment being due quarterly thereafter. Such
payments shall be in the amounts set forth in Part B of Schedule II to this
Agreement, it being understood that the aggregate amount paid will exceed the
Purchase Price set forth in Schedule I because the amounts set forth in said
Part B include an interest calculation. The amounts set forth in Part B of
Schedule II to this Agreement may be prepaid, in whole or in part, by Purchaser
at any time. In the event of prepayment, the installments shall be reduced to
their present value calculated at 12% per annum, to the date of payment. Title
in the IRU to the Purchased Capacity shall pass to Purchaser upon payment to the
Grantor's Account of the amount specified in the first sentence of this
paragraph.

     The parties agree to co-operate in good faith to structure payments
hereunder so that the interest component thereof should not be subject to
withholding taxes under current law (at the time the first payment is made
hereunder) in the reasonable opinion of the Grantor and the Purchaser; provided
that if in the Grantor's reasonable opinion such interest component will be, or
if at any time prior to the first installment payment hereunder, the Internal
Revenue Service asserts that such interest component is, subject to withholding
taxes under current law, the Grantor will reduce the 12% per annum interest rate
payable hereunder such that the total interest cost (including withholding taxes
payable on such reduced interest rate) to the Purchaser will not exceed 12% per
annum.

     The definition of the term "Purchase Price" contained in the Capacity
<PAGE>

Purchase Agreement shall be modified to add the following phrase immediately at
the end of said definition:

     , as such amount may be adjusted and paid in accordance with Part B of
     Schedule II to this Agreement.

     Clause (ii) of Section 20 (c) of the Capacity Purchase Agreement shall be
modified to include the following phrase immediately after the phrase
"maintenance expenses":

     and in respect of payments for the Purchase Price for Purchased Capacity.


                                     Part B
                                     ------

          The attached amortization schedule sets forth the dates and amounts
     for installment payments for Purchased Capacity based on the Purchase Price
     as set forth in Schedule I.

          Notwithstanding anything to the contrary in Section 21, the right to
     receipt of payments hereunder shall be transferable only upon surrender for
     cancellation of this Schedule II, and the issuance of a new Schedule II
     registered in the name of the transferee. In addition, the Purchaser shall
     maintain a register in which it shall record the name of the Grantor and
     the Subsidiary Grantors or any transferee, and no transfer shall be valid
     unless so registered.

          Capitalized terms used in this Schedule II and not otherwise defined
     in this Schedule II shall have the meanings assigned to them in the
     Capacity Purchase Agreement.

          This Schedule II shall be deemed a part of the Capacity Purchase
     Agreement with respect to each Purchaser signing this Schedule II below and
     the terms set forth in this Schedule II shall be incorporated into the
     Capacity Purchase Agreement with respect to each such Purchaser as if fully
     set forth therein.

          Purchaser hereby represents and warrants that its chief executive
     office is located at 12100 Sunset Hills Road, Suite 110, Reston, VA 20190.
     Purchaser agrees to promptly notify Grantor of any change in such location.

                           CAPACITY PURCHASE AGREEMENT

                        MAINTENANCE PERFORMANCE STANDARDS


1.   GENERAL

This Schedule IV supplements the Capacity Purchase Agreement and describes (i)
additional maintenance and performance responsibilities of Grantor to Purchaser
and (ii) certain remedies available to Purchaser with respect to the provision
of Purchased Capacity thereunder. Capitalized terms used in this Schedule
without separate definition shall have the meanings specified in the Capacity
Purchase Agreement, as the context requires.

2.   OVERVIEW

Grantor is initially providing to Purchaser an STM-1 "SDH self-healing ring
protected" service between New York City, New York, USA, and London, UK. This
Schedule applies to such capacity and to any further capacity provided by
Grantor to Purchaser.

While Purchaser understands that Grantor may sub-contract some services, such as
terrestrial backhaul and/or maintenance services with respect to the System and
the Purchased Capacity, such sub-contracting is transparent to Purchaser, and
therefore, Grantor shall appear as the single vendor providing these services to
Purchaser.

3.   NETWORK OPERATIONS CENTER (NOC)

Grantor shall maintain a round-the-clock NOC (i.e., it operates 24 hours a day,
seven days a week), which shall be staffed by trained and qualified personnel
who are familiar with the operation and maintenance of the System and the
Purchased Capacity. Grantor shall provide Purchaser with a NOC telephone number,
which Purchaser shall use to report troubles with respect to the use of the
Purchased Capacity, to input service requests, and to request service
information.

4.   TROUBLE REPORTING AND RESOLUTION

When Purchaser reports a major service affecting trouble (i.e., the Purchased
                                                          ----
Capacity fails to meet the standards set forth in the Capacity Purchase
Agreement or this Schedule or connectivity is lost between two or more of the
cities in which service is purchased) Grantor will, without interruption, work
the trouble to completion. When a service affecting trouble (as described
herein) occurs, the Grantor NOC will provide updates to Purchaser in accordance
with Grantor's standard practices.

Prior to activation of any part of the Purchased Capacity, Grantor shall provide
Purchaser with an operations management organization chart showing the
escalation path for reporting service affecting troubles. Purchaser shall be
provided the telephone

                                                                     Page 2 of 3

numbers, through the Vice Presidential level, for the escalation of service
affecting troubles. Grantor shall promptly update such chart to reflect any
changes.

5.   SYSTEM PERFORMANCE STM-1

This section applies to the STM-1 capacity, including without limitation the S
Capacity, the T Capacity and any connecting backhaul or inland capacity.

5.1  STM-1 to STM-1 Transmission

Grantor shall provide STM-1 to STM-1 transmission of 155 Mbps clear channel
capacity service. Grantor shall provide both service and protection pairs to
Purchaser at each offered termination point of the service.

STM-1 Transmission Performance shall equal or exceed the standards shown in
column AC-1, below:

Grantor commits this SESR and this BBER to the performance standard throughout
the life of the system.

5.2  Protection Switching

Grantor shall provide protection switching in respect of the AC-1 System in the
following forms:

Span Switching - protects against a failure affecting the service line traffic
between service termination points. Span switching reroutes service traffic onto
the protection fiber pair in the common cable segment.

- ----------------------------
1  Severely Errored Second Ratio

2  Background Bit Error Ratio

                                                                     SCHEDULE IV
                                                                     Page 3 of 3

Ring Switching - protects against a failure affecting both the service and
protection fibers in one cable segment between service termination points. Ring
switching reroutes service traffic over the other cable segments in the ring.

Grantor shall protect the STM-1 service against a single cable failure in less
than 300 ms (milli-seconds).

5.3  Service Traffic

Grantor shall provide a common protection facility shared by all switching nodes
or landing sites, which provides for full service traffic capacity in the event
of a failure.

5.4  Service Traffic Availability

Grantor's STM-1 155 Mbps "SDH self-healing ring protected" service between
Purchaser's interfaces shall have a service availability of at least 99.995 %.
This availability figure equates to no more than twenty-six (26) minutes of
service outage in any given twelve (12) month period.

Excluded from this calculation shall be planned service outages for the purpose
of Purchaser initiated upgrades or modifications to the service.

Service availability will be maintained and calculated monthly based on the
following formula:

                              Time Service Available
         Availability (%) = -----------------------------------------------
                              Time Service Scheduled to be Available

In the event that the service falls below 99.995%, Grantor will, for a maximum
period of thirty (30) months, credit forty (40%) percent of any month's OA&M
where service levels fall below the 99.995% threshold listed above. The credit
will be applied to the following quarter's OA&M charges.

5.5  Routing Capability

Grantor confirms that any STM-1 tributary and any landing site can be routed in
either direction of transmission to any other landing site, providing maximum
flexibility in traffic provisioning between the landing sites.

5.6  STM-1 Backhaul

Grantor will, where terrestrial backhaul providers are used to complete the
STM-1 transmission facilities, ensure that such backhaul is ring and span
protected with geographically diverse routes and entry points into the service
termination points.

5.7  Mean-Time-Between-Failure (MTBF) / Mean-Time-To-Restore (MTTR)

Grantor shall protect the STM-1 service against a single cable failure in less
than 300 ms (milli-seconds).

Order Confirmation

The information that is provided on this form is straight forward and serves
only to indicate to you that Customer Care has received your RFS and is
beginning to process the Request.  The ITU Circuit Designation is the name you
have called the circuit.  The Order Number is the installation order number that
Global Crossing has assigned to the installation order.  The scheduled due date
is the requested date you placed on the RFS.  The Overseas Channel Assignment is
the identification number of the undersea portion of the circuit.

Assignment Order

The information for the Assignment Order will come to you after Global Crossing
has designed the circuit.  This form can be sent to the Inland Provider, the
Alternate Access Vendor or the Local Loop Provider that you have contracted for
your portion of the circuit.  It tells them what assignments have been made on
the Global Crossing portion of the circuit.

Order Completion

Once notification is received from the NOC that the order has been completed, we
will notify you using the Order Completion Form.  The information on this form
tells you that the Order has been completed, the date it was completed, the ITU
Circuit Designation, the Overseas Channel Assignment, the Order type (add,
disconnect or change) and the Bay, Panel and Jack information for extended
service.

Activation Authorization

The Activation Authorization will be sent to you once the circuit has been
completed and we have verified that all financial obligations have been met.  It
authorizes the Capacity Providers that you have contracted with to turn up the
service associated with the listed circuit(s).

                          TRANSFER OF SERVICE AGREEMENT

Current Customer: _________________________________________________________

New Customer: _____________________________________________________________

Atlantic Crossing Ltd. Service(s) to be transferred (referred to in this
Agreement as the "Identified Service"): are outlined in Attachment A.
___________________________________________________________________________

1.  Current Customer is Atlantic Crossing Ltd.'s existing customer of record for
the identified Service.  Current Customer hereby requests that Atlantic Crossing
Ltd. transfer the Identified Service to New Customer.  Current Customer
understands that it will no longer be Atlantic Crossing Ltd.'s customer for the
identified Service after the Effective Date of the transfer.

2.  New Customer agrees to assume all obligations of Current Customer as of the
Effective Date of the Transfer.  These obligations include, for example: all
outstanding indebtedness for the Identified Service and the ongoing maintenance
and interconnection charges (where applicable).  This transfer of service does
not relieve or discharge Current Customer from remaining jointly and severally
liable with New Customer for any obligations existing as of the Effective Date

     WHEREAS, each Subsidiary Grantor is a wholly-owned subsidiary of Atlantic

Agreement (as amended, supplemented or otherwise modified from time to time, the
"Capacity Purchase Agreement") to which a copy of this Agreement is attached;

     WHEREAS, capitalized terms used in this Agreement and not otherwise defined

this Agreement will not enable you to refuse to pay those amounts to us.

4.5    Force Majeure

4.5.1  Neither party will be liable to the other for any failure to perform its
       obligations under this Agreement if anything happens beyond its
       reasonable control, which includes but is not limited to an Act of God,
       inclement weather, act or omission of government or other competent
       authority, military operations, war, riot, insurrection, or other civil
       disturbance. Failure of a subcontractor to either of the parties to
       fulfil its obligations to such party shall not be deemed to be an event
       beyond the reasonable control of such party for purposes of this
       Agreement.

4.5.2  If as a result of any such circumstances we are unable to perform this
       Agreement and the Capacity is unavailable for use by you for a period
       longer than sixty (60) days, you shall be entitled, upon written notice
       to us, to terminate this Agreement and receive a pro-rata refund of any
       amounts paid with respect to the IRU in the Capacity based upon the
       remaining term of the Duration plus a pro-rata portion of any maintenance
       paid for the term then in effect plus any amount paid for any future
       maintenance term.

4.6    Liability

Neither party limits its liability for causing death or personal injury due to
its negligence or intentional misconduct.

The maximum liability either party has to the other under this Agreement for any
direct loss, other than payments properly due under this Agreement, is limited
to (Pounds)1,000,000 (one million pounds sterling) for any one event or series
of connected events, subject to a maximum of (Pounds)5,000,000 (five million
pounds sterling), in any twelve month period.

Neither party will  be liable to the other for any indirect or consequential
loss or damage, which includes loss of bargain, loss of business, loss of
contract, loss of future profit, loss of opportunity, loss of savings, loss of
sales, or loss of turnover including negligence however caused.

Our relationship is with you and therefore you also agree to indemnify us from
any claims from a third party who has a relationship with you where you supply
services over the iaxisenroute network.

4.7    Waiver and Severability

No delay, tolerance, or indulgence by either party shall constitute a waiver of
its rights and in the event that any part of this Agreement is found to be void,
invalid or unenforceable, it will not affect the remainder of the Agreement.

4.8    Maintenance

We will give you at least 5 days notice of our intention to carry out any
scheduled maintenance that might affect you or the provision of the Capacity to
you.  Sometimes we need to carry out emergency maintenance and if we do, we will
give you as much notice as is reasonably possible in the circumstances.

4.9    Internal Escalation

Should a dispute arise between the parties, both parties will attempt to resolve
the dispute in accordance with the following procedure:

Any dispute which cannot be resolved within 14 days of first arising may be
escalated to a line manager (or equivalent) in writing, and if it is not
resolved within a further 7 days, may be escalated by notice in writing to
senior management:

i)     Our line manager is the Director of Operations
       Your line manager is the ISP Systems Engineer

ii)    Our senior management is the Chief Operating Officer and/or Chief
       Executive Officer. Your senior management is the President and/or Chief
       Executive Officer.

The procedure in this paragraph does not prevent either party from having
recourse to the courts if the circumstances necessitate it.

parties agree to have it dealt with in the exclusive jurisdiction of the English
Courts.

Notes

1.  Open Optical Link (OOL) breakout capability is currently available at all
Phase 1 PoPs except for the Strasbourg/Kehl PoP which will be available in
October 1999.

2.  Additional breakout points may be provided at Customer's request (at
additional cost).


1.2  iaxisenroute Pan-European Network

iaxis will use its best endeavours to deploy the iaxisenroute network throughout
Europe in three distinct phases (or rings). Phase 1 will be lit by June 1st;
Phase 2 should be lit by September 31st; and Phase 3 should be lit by December
31st 1999.

The iaxisenroute fibre ring comprises 1 fibre pair and employs advanced Ciena
DWDM technology to increase bandwidth capacity.  The Ciena equipment provides
initially for up to 40 distinct wavelengths at a capacity of 2.5 Gigabits per
wavelength (a total of 100 Gigabits).  Based on Ciena technology currently under
development and expected to be available in July 2000, iaxis should be able to
expand the iaxisenroute network capacity to 96 wavelengths, and by December 2000
to 192 wavelengths each with 10 Gigabits of capacity, which will bring the total
capacity to two Terabits.  iaxis can achieve this increase in capacity on its
existing pair of fibre optic cables without laying or leasing additional fibre
optic cables or incurring significant costs and network downtime.  iaxis is the
first telecommunications company in Europe to utilise Ciena's 96-wavelength
system technology.

2.0  Network Operations & Fault Management

2.1  Overview

iaxis will manage the network 24 hours a day * 7 days a week * 52 weeks a year
from its Network Operations Centre (NOC). A full-time NOC team manages the
network to ensure stated service levels are achieved. The NOC shall proactively
monitor services and automatically flag service-affecting faults. Customer shall
be notified and fault reports shall be made available to the Customer whenever
service-affecting faults occur.

The NOC is a secure facility offering a Single Point of Contact (SPOC) for all
iaxis Customer calls and is the interface between Customer and iaxisenroute
Network Operations.  A single telephone number in the NOC will be provided where
all calls are processed.

iaxis will provide a single point of contact (SPOC) for use by Customer to
address payment issues and provide billing support.

Customer will have remote access capability to allow direct monitoring of
network performance.


2.2  Fault Reporting and Service Levels

All faults will be reported to iaxis Network Operations personnel on a number
located in the iaxis NOC.  Faults may also be automatically detected by one of
the network management tools available to the Network Operations Centre
engineers. On receipt of a fault report or automatic detection of a fault, NOC
engineers shall initiate primary diagnostics with the intent of clearing the
fault remotely.  If this is not possible, first-line maintenance personnel shall
be despatched to site to clear the fault. Iaxis shall also inform Customer of
the fault and shall continue to provide updates and advisory information
necessary to keep Customer fully informed of progress towards fault resolution
and restoration of service.

All faults shall be recorded on the iaxis Fault Management System (FMS). The FMS
shall record all faults, date and time stamp them, and maintain a true and
accurate record of the progress of the fault resolution through to clearance.
The FMS shall permit tracing of all faults from initiation through to clearance.
Faults shall be recorded in sufficient detail to allow detailed post-fault
analysis and ensure that a record of the fault and actions taken is available
for future reference.

iaxis enters into a detailed Service Level Agreement (SLA) with each of its
fibre and equipment suppliers as well as each of its Customers. The FMS
configuration shall permit automatic checking of all faults against prevailing
SLAs to ascertain whether or not criteria have been met.  All SLAs shall be
agreed prior to the service being handed over to ensure that the performance
criteria are both realistic and achievable.

Customers shall be able to view on-line their own service faults via a password
and username accessed web screen. This functionality will be further expanded
(date still to be finalised) to enable Customers to view progress associated
with service provisioning.

4.2  Escalation Procedure

The flow diagram in Figure 2 outlines the Escalation Procedure that the iaxis
NOC uses whenever a fault needs to be escalated to a higher level within the
organisation. In finalising the operational interfaces between the Customer and
iaxis, it is accepted that the Escalation Procedure may need to be refined.


Escalation path is as follows:

The flow diagram in Figure 4 outlines the Service Interruption Procedure that
iaxis NOC follows whenever a planned service interruption occurs.

 .  Network outage requested by iaxis

 .  Network Operations pass to NOC for network and Customer impact analysis

 .  NOC report findings back to Network Operations

 .  If authority to proceed not received, outage rescheduled, postponed or
   abandoned

 .  Customer notifications sent out, warning of service interruption

 .  If authority to proceed not received from Customer, outage rescheduled,
   postponed or abandoned

 .  NOC produce outage record

 .  Outage carried out in accordance with planned work procedure

 .  If outage did not proceed as planned, Network Operations carry out post-
   failure investigation

 .  After outage, Network Operations produce report, review and recommendations

 .  In the event of planned works being imminent, when an unplanned outage on
   another part of the network occurs, the planned works shall be postponed
   until the fault has been cleared.

4.5  Management Reporting

The iaxis NOC will provide the following reports, to be delivered via e-mail or
other media as required by Customer, to Customer's NOC, and to other recipients
designated in writing by Customer:

 .  Fault report detailing Customer or network faults - analysis within 24 hours

 .  Ad-hoc Customer service reports, including:

   .  Service availability
   .  Service interruptions and downtime
   .  Service delivery against requirements
   .  Total number of faults
   .  Fault resolution against SLA


4.6  Planned Maintenance

iaxis shall maintain its buildings and equipment. Accordingly iaxis shall
provide its Customers with a comprehensive maintenance schedule which covers all
aspects of iaxis planned maintenance activities. It will include, among other
things, planned maintenance for active equipment, fibre, buildings and building
services.  The network may be maintained by a number of parties under the
control of the iaxis Network Operations Manager who shall have overall
responsibility for the operational network.

iaxis shall perform preventive maintenance on all equipment contributing to the
iaxis network in accordance with manufacturers' specifications.

Planned maintenance activities will only be undertaken after prior consultation
with the Customer has taken place, and when the timing, frequency and duration
of the planned outage(s) has been mutually agreed. In situations where emergency
maintenance (e.g. for potentially service affecting faults) is required, prior
permission may not be sought from the Customer.

Downtime as a result of planned maintenance outages will not be included in the
Service Availability calculations and consequently will not incur compensation
payments from iaxis.


4.7  Customer Visits

Customer shall have the right to visit the iaxis NOC to observe NOC operations,
procedures, capabilities and equipment.  Should Customers wish to visit the
iaxis NOC iaxis will agree mutually convenient times and make appropriate
arrangements for Customer visits in advance.

5.0  Service Levels and Compensation Schemes


iaxis is committed to providing high quality point-to-point and managed
bandwidth services to our Customers. This section details the service levels and
compensation schemes that apply to iaxis service provision.


5.1  Services Covered

All Open Optical Links and managed bandwidth services between the iaxis PoPs.


5.2  Ready For Services (RFS) Dates

iaxis target Ready For Service (RFS) dates are:

   .  7 days for DS3 and STM-1 circuits
   .  10 days for STM-4 and OOL circuits
   .  15 days for STM-16 circuits.

When an order is placed with iaxis the RFS date shall be confirmed in writing.
If iaxis fails to meet this date and cannot demonstrate that the delay was
caused by circumstances beyond its reasonable control, the Customer shall be
entitled to compensation for late delivery.

For IRUs compensation will be in the form of a credit of 1% of the annual
Operating & Maintenance (O&M) charge for each working day or part thereof beyond
the agreed RFS date (up to a max. of 50 days).

For rentals compensation will be in the form of a credit of 1% of the annual
rental charge for each working day or part thereof beyond the agreed RFS date
(up to a maximum of 5 days).


5.3  Services Restoration Time (SRT)

The fault resolution process will be initiated immediately a fault has been
auto-detected by the FMS or has been reported to the NOC by the Customer.

In the event that iaxis fails to repair service-affecting faults of either fibre
or equipment within the Target Repair Time (TRT), measured from the agreed fault
start time, the Customer shall be entitled to compensation as detailed in the
table below.  The Target Repair Time (TRT) referred to below is defined as the
time from the agreed fault start time to the time that the service is restored.

Circuit Availability will be calculated on a quarterly basis from the
anniversary of the RFS date. The total time of Service Availability (SA) is
calculated as follows:

SA = (Ts * 100)/MST %

Where:

     Ts   = Total time for which service is available across all circuits during
          the previous 3 month period

     MST  = Maximum Service Time, the total amount of time (maximum circuit
            minutes) which the service could have been available across all
            circuits i.e. the number of circuit minutes for 100% availability in
            a given 3 month period.


5.5  Cancellation of Service by Customer

If a service is cancelled prior to the RFS date, iaxis reserves the right make a
Cancellation Charge to cover costs incurred as a result of the cancellation. The
level of these charges is laid out in the table below.

8.0  SDH Service - Technical Overview

8.1  Managed SDH Service

iaxis shall provide the Customer with SDH circuits as described in this Section.
Circuits shall be presented to Customer at the System Interface Points, which
shall be located in the iaxis Points of Presence set forth in the Agreement
unless otherwise jointly agreed to in writing by iaxis and Customer. Circuit
hand-off and presentation shall conform to applicable industry standards, to the
technical specifications set forth in this Agreement, and to Customer's
requirements as detailed in writing by Customer as part of the circuit
provisioning process.


8.2  iaxisenroute SDH Network

The iaxisenroute network is the terrestrial fibre optic cable system (initially
operating at per wavelength digital transmission capacity of 2.5 Gbit/s),
initially with the configuration set forth in this Agreement, and all plant and
equipment between and including all the System Interface Points, including all
SDH and OOL equipment, as such shall be modified and upgraded from time to time.


8.3  Main Advantages of the iaxisenroute SDH Network

 .    Simplified multiplexing/demultiplexing techniques compared to PDH.

 .    Access to lower speed tributaries without the need to multiplex/demultiplex
     the entire high-speed signal. This facilitates efficient drop and insert of
     channels and cross connect applications.

 .    Embedded network management channels that provide enhanced Operations,
     Administration and Maintenance (OAM) capabilities enabling the network to
     be more efficiently controlled.

 .    Facilitates easy growth to higher multiplexing levels.

 .    Enables the transport of digital signals at the hierarchy bit rates
     specified in ITU-T Recommendation G.702 and at broadband channel bit rates.
     This permits SDH equipment to be introduced directly into existing networks
     and also facilitates the introduction of a wide range of additional
     services.

 .    Defines an optical interface that allows mid span fibre meets between
     equipment from different suppliers.


8.4  Conformance to Standards

The iaxisenroute network shall conform to ITU-T Recommendation G.707 - Network
Node Interface for the Synchronous Digital Hierarchy, and other published
standards and recommendations including (but not limited to) ITU-T G.702, G.708,
G.709, G.781, G.782, G.783, G.803, G.826, G.957, and G.958, which detail the
international standards covering synchronous digital multiplexing and
transmission systems


                                                                   Page 26 of 30
<PAGE>

8.5  Functionality

ITU-T Recommendation G.702, and others, define the line rates permitted in and
supported by SDH networks. The iaxisenroute network will offer equipment and
configurations capable of supporting the following data rates:


- ------------------------------------------------------------------
   Synchronous Transport Module             Line Rate (Mbps)
- ------------------------------------------------------------------
               STM-1                            155 Mbps
- ------------------------------------------------------------------
               STM-4                            622 Mbps
- ------------------------------------------------------------------
              STM-16                            2.5 Gbps
- ------------------------------------------------------------------



Although the ITU-T has defined the STM-1 data rate as the basic building block
of all SDH networks, allowances were made for any of the current transmission
rates to be mapped into an STM-1. This is done by using Virtual Containers,
which can be combined into standard formats in order to form the payload of the
STM-1 signal. Different containers can be mixed, allowing for different rates to
be carried simultaneously with the same structure.

Therefore, iaxisenroute network will supply STM-1 and STM-4 signals as well as
support mapping of E1 signals into VC-12s, and E3 and DS-3 signals into VC-3s
allowing for a complete range of traffic signals which can be both added to
and/or dropped from the iaxisenroute network.


8.6  Protection Approach

The ITU-T, when defining the content of SDH allowed for an overhead that would
carry management information. This is broken down into the following:

 .    Path Overhead - including trace, labelling, error monitoring and status
     information for PDH Signals

 .    Regenerator Section Overhead - including framing, error monitoring, trace
     and data communications information, and

 .    Multiplexer Section Overhead - including error monitoring, automatic
     protection switching, data communications and synchronisation status
     information

Practical uses of the overhead extend to flexible management of the iaxisenroute
network. Automatic protection switching data, otherwise known as K-bytes, K1 and
K2, carries information on faults throughout the network. Where a fault such as
a broken fibre occurs in the network the K-bytes carries messages throughout the
network instructing the network elements to take appropriate action to minimise
traffic disruptions.

iaxisenroute network shall employ a protection mechanism called 2-Fibre
Multiplexer Section Protection Ring (2F MSPRing) throughout the network. This is
a very efficient protection strategy defined in the ITU-T recommendation G.841,
which allows eight of the STM-1s in an STM-16 channel to be used for protection.
Where a protection switch occurs the traffic that would otherwise be lost is
transported around the ring using these protection channels. The tributaries are
protected by adopting a 1+1 protection scheme consisting of two identical
channels per tributary - one working and one protecting - both of which may
carry traffic.


                                                                   Page 27 of 30
<PAGE>

By utilising the 2F MSPRing protection strategy combined with 1+1 protection
switching at the tributary level throughout the iaxisenroute network, iaxis will
deliver a service availability of 99.99%.


8.7  Network Management Capability

The Data Communications Channel (DCC) in the overhead is used to carry
miscellaneous information throughout the network as well as being the main route
for management information from the Network Operations Centre (NOC) to the
Network Elements (NE).

The iaxis NOC is situated in London with the NEs being distributed throughout
Europe. iaxis uses an E1 to connect the Integrated Network Manager (INM) to a
gateway NE at Telecity. The DCC then carries information throughout the network.
Through the DCC the Network Operator can remotely configure the network, check
for alarms and download new software from a single site. For example, should the
network SDH equipment require a software upgrade, the download can be initiated
from the INM to every NE in the iaxisenroute network without having to visit any
remote site. This management feature allows for flexible reconfiguration and
surveillance of the network.

It is also possible to reconfigure the network remotely from the iaxis NOC.
Physical connections to the ports (where the connections originate and
terminate) can often be made in advance of the actual provisioning of a circuit.
Accurate forecasting of network circuit requirements can significantly reduce
the period between the actual ordering of circuits and their being provisioned.

       copyright Act of 1976, Title 17 USC Section 101 et. Seq.) or any
       intellectual property rights related thereto, whether by implication,
       estoppel or otherwise, except those rights expressly granted in this
       Section 2.

3    LICENSE RESTRICTIONS

3.1    Licensee agrees, except to the extent provided by Section 2.1 above, that
       it will not itself, or through any parent, subsidiary, affiliate, agent

3.1.1     sell, lease, license, sublicense, or encumber with any portion of the
          Licensed Software or Documentation;

3.1.2     except to the minimum extent necessary to comply with EC Directive, if
          applicable, or other applicable legislation, decompile, disassemble,
          or reverse engineer any portion of the Licensed Software or attempt to
          discover any source code or underlying ideas or algorithms of any
          Licensed Software;

3.1.3     other than to the extent permitted by Section 2.4 above, create any
          Derivative Work based on the Licensed Software or any Portal
          Confidential Information;

          Software to provide processing services to third parties, commercial
          timesharing, rental or sharing arrangements, or on a "service bureau"
          basis or otherwise use or allow others to use the Licensed Software
          for the benefit of any third party;

3.1.5     provide, disclose, divulge or make available to, or permit use of the
          Licensed Software by persons other than employees and subcontractors

          obligations consistent with the terms and provisions herein, without
          Portal's prior written consent;

3.1.6     use any Licensed Software, or allow the transfer, transmission,
          export, or re-export of any Licensed Software or portion thereof in
          violation of any export control laws or regulations administered by
          the U.S. Commerce Department, OFAC, or any other government agency.
          All the limitations and restrictions on the Licensed Software in this
          Agreement also apply to the Documentation. At the present time, Portal
          warrants that as of the Effective date the Licensed Software may be
          exported to the European Union, Switzerland, Brazil, Argentina and/or
          Mexico.

4    PAYMENTS AND TAXES

4.1    Unless otherwise agreed in writing, all payments due hereunder shall be
       made in U.S. dollars. In addition to any remedies Portal may have
       hereunder or at law, any payments more than forty five (45) days overdue
       will bear a late payment fee of 1.5% per month, or, if lower, the maximum
       rate allowed by law. Delinquency in payment will result in a delay or
       suspension of the Licensed Software implementation timetable or services
       (including Support Services) provided by Portal. Resumption of services
       will occur after Licensee has brought itself current on all of its
       outstanding payment obligations to Portal. The services will be scheduled
       in accordance with the availability of Portal resources. Portal will not
       be liable for any damages caused by rescheduling of suspended services
       pursuant to this Section 4.1.

4.2    Licensee agrees to pay or reimburse Portal for all federal, state,
       dominion, provincial, or local sales, use, personal property, payroll,
       excise or other taxes, fees, or duties arising out of this Agreement or
       the transactions contemplated by this Agreement (other than taxes on the
       net income of Portal.) If any tax is payable by Licensee under this
       Section 4.2, then the Licensee shall provide evidence of payment to
       Portal and Portal shall use all reasonable efforts to obtain a credit,
       rebate, or benefit for that amount against its own tax, and if it
       receives such credit, rebate, or benefit it shall refund to Licensee an
       amount equal to the lesser of the amount paid by Licensee and the credit,
       rebate, or benefit obtained by Portal.

5    LICENSE FEE

In consideration of the rights granted herein, Licensee shall pay Portal the
license fee(s) as set forth in Schedule A. 6 Maintenance and Technical Support

6    MAINTENANCE AND TECHNICAL SUPPORT

6.1    Upon payment of the annual maintenance and support fee set forth on
       Schedule A, Licensee shall be entitled to receive Updates and technical

     renew Support Services, Licensee must first pay Portal the then current
     annual support services fee and all past support service fees. In the event
     Licensee fails to make any required payment or in the event Licensee
     breaches any of its material obligations under the Support Services
     provisions and such breach has not been cured within sixty (60) days of
     receipt of notice of breach, Portal may suspend or cancel Support Services.
     No Updates of the Licensed Software will be provided to Licensee and no
     Updates may be copied by Licensee to update any copies of the Licensed
     Software unless Support Services have been purchased for such copies.
     Support Services fees shall be billed on an annual basis, payable in
     advance.

6.3  Portal shall have no obligation to support (a) altered, damaged or modified
     Licensed Software (except as authorized by Portal) or any portion of the
     Licensed Software incorporated into other software, (b) Licensed Software
     that is not the then current or immediately previous sequential release,
     but in any event Portal shall support each major release of the Licensed
     Software for at least eighteen (18) months from its initial applicable
     release date and at least six months from the initial general availability
     of the next major release, (c) problems caused by Licensee's gross
     negligence, abuse, or misapplication, or use of the Licensed Software other
     than as specified in all material respects in Portal's user documentation
     or other causes beyond the control of Portal, or (d) Licensed Software
     installed in an operating environment or hardware environment for which the
     Licensed Software has not been licensed. Portal shall have no liability for
     any changes in Licensee's hardware which may be necessary to use the
     Licensed Software.

6.4  Portal reserves the right to change its technical support guidelines and
     procedures provided (i) Portal provides Licensee with at least sixty (60)
     days prior written notice of such changes, and (ii) such changes do not
     diminish Portal's overall technical support obligations to Licensee in any
     material respect.

7    Restricted Release

If Licensee is selected for participation and elects to participate in a
Restricted Release program, Licensee agrees (i) Portal shall have no obligation
to correct errors in or deliver updates to the Restricted Release, (ii) Portal
shall have no obligation to otherwise support the Restricted Release, (iii)
Licensee will provide Portal with appropriate test data for the Restricted
Release if necessary to resolve problems in the Restricted Release encountered
by Licensee and will promptly report to Portal any error discovered in the
Restricted Release, (iv) the Restricted Release is experimental, may contain
problems and errors and is being provided to Licensee on an "AS-IS" basis with
no warranty of any kind, express or implied, (v) neither party will be
responsible to the other for any losses, claims or damages of whatever nature,
arising out of or in connection with the performance or nonperformance of the
Restricted Release, (vi) Licensee will not use the Restricted Release in
production applications without the prior written approval of Portal, and (vii)
Licensee will stop using and return or destroy any Restriction Release promptly
upon Portal's request.

8    Termination

8.1  This Agreement commences on the Effective Date and will remain in force
     until it is terminated.

8.2  Portal may, by written notice to Licensee, terminate this Agreement if for
     nonpayment or if Licensee is in breach in any material respect of Sections
     2, 3, or 14 of this Agreement, which nonpayment or breach is not cured
     within thirty (30) days after Portal gives Licensee written notice of such
     breach;

8.3  Termination will become effective immediately or on the date set forth in
     the written notice of termination and any payment obligations under this
     Agreement shall immediately become due and owing. Termination of this
     Agreement will not affect the provisions regarding Licensee's or Portal's
     treatment of Confidential Information, provisions relating to the payments
     of amounts due, provisions limiting or disclaiming Portal's liability,
     and/or provisions regarding applicable law, which provisions will survive
     termination of this Agreement. In the event of such termination of this
     Agreement or any Licensed Software product license granted hereunder,
     Portal will promptly refund all applicable pro-rated, prepaid annual
     maintenance Support Services fees relating to the period following the
     termination.

8.4  Upon termination, all licenses granted hereunder shall cease to be
     effective and Licensee shall immediately cease all use of any affected
     Licensed Software, Documentation and Portal Confidential Information.

8.5  Within fourteen (14) days of the date of termination or discontinuance of
     this Agreement for any reason whatsoever, Licensee shall return the
     Licensed Software and all copies thereof, in whole or in part, all related
     Documentation and all copies thereof, and any other Confidential
     Information in its possession. Licensee shall furnish Portal, at Portal's
     request, with a certificate signed by an executive officer of Licensee
     verifying that the same has been done.

8.6  Termination is not an exclusive remedy and all other remedies will be
     available whether or not termination occurs.

9    Patent and copyright indemnity

9.1  Portal will defend and indemnify Licensee for all costs (including
     reasonable attorneys fees) arising from a claim that the Licensed Software
     infringes a copyright or patent or constitutes a violation of a trade
     secret provided that (i) Licensee notifies Portal in writing within thirty
     (30) days of the claim (ii) Portal has sole control of the defense and all
     related settlement negotiations, and (iii) Licensee provides Portal with
     the assistance, information, and authority necessary to perform the above;
     reasonable out-of- pocket expenses incurred by Licensee in providing such
     assistance will be reimbursed by Portal.

9.2  Portal shall have no liability for any claim of infringement based on (i)
     use of a superseded or altered release of the Licensed Software, except for


Software License & Support Agreement                                 Page 3 of 7
<PAGE>

                       PORTAL PROPRIETARY & CONFIDENTIAL


     which alteration(s) or modification(s) has been made by Portal or under
     Portal's direction, if such infringement would have been avoided by the use
     of the current unaltered release of the Licensed Software that Portal
     provides to Licensee, or (ii) the combination, operation, or use of any
     Licensed Software furnished under this Agreement with programs or data not
     furnished by Portal if such infringement would have been avoided by the use
     of the Licensed Software without such programs or data.

9.3  In the event that the Licensed Software is held or believed by Portal to
     infringe, or Licensee's use of the Licensed Software is enjoined, Portal
     shall have the option, at its expense, and preferably in the following
     order to the extent commercially practicable, (a) obtain for Licensee a
     license to continue using the Licensed Software, (b) modify the Licensed
     Software to be non-infringing in a manner that does not materially reduce,
     restrict or adversely impact the functionality of the Licensed Software,
     (c) substitute the Licensed Software with other software reasonably
     suitable to Licensee, or (d) if none of the foregoing remedies are
     commercially feasible, terminate the license for the infringing Licensed
     Software and refund the fees paid for that Licensed Software, prorated over
     a five-year term from the Effective Date of this Agreement or applicable
     amendment or additions schedule. This Section 9.3 states Portal's entire
     liability for infringement.

10   Warranty

10.1 Portal warrants that it has title to and/or the authority to grant licenses
     of the Licensed Software, including without limitation, any third party
     products that may contained therein or distributed therewith.

10.2 Portal warrants to Licensee that the Licensed Software will perform in
     substantial accordance with the Documentation for a period of one hundred
     eighty (180) days from the Effective Date. If the Licensed Software does
     not perform as herein warranted, Portal shall undertake at its own expense
     to correct the non- conforming part of the Licensed Software. If correction
     is not reasonably possible or commercially practicable, Portal shall refund
     the monies paid by Licensee for that non-conforming Licensed Software.

10.3 Portal warrants that the Licensed Software is designed to be used prior to,
     during and after the calendar year 2000 and that the Licensed Software will
     operate during each such time period without error relating to, or the
     product of, date data which references different centuries or more than one
     century. If the Licensed Software does not perform as warranted, Portal
     shall undertake at its own expense to correct the non-conforming part of
     the Licensed Software, or if correction is reasonably not possible, replace
     such non-conforming part of the Licensed Software free of charge. If
     neither of the foregoing is commercially practicable, Portal shall refund
     the license and annual maintenance support fees paid by Licensee for the
     non-conforming Licensed Software. If a refund is made in the manner herein
     contemplated, the parties will amend the definition of "Licensed Software"
     in Schedule A to reflect the same. The foregoing Year 2000 Warranty shall
     not apply (i) if the Licensed Software is used or interfaced with other
     software, data or operating systems which are not Year 2000 compliant, (ii)
     if the Licensed Software has been modified in a manner not authorized by
     Portal, or (iii) if Licensee fails to install an Update if the
     non-compliance would have been avoided by installation of such Update.

10.4 Portal's warranty obligations as set forth above are made to and for the
     benefit of Licensee only and shall be enforceable against Portal only if:

10.4.1 The Licensed Software has been properly installed and has been used
       at all times in accordance with the Documentation and this Agreement;

10.4.2 All modifications, alterations or additions to the Licensed Software, if
       any, have been made using Licensed Software Customization Tools provided
       by Portal to Licensee or in a manner authorized by Portal.

10.5 Except as set forth in this Section 10, Portal makes no warranties, whether
     express or implied, or statutory regarding or relating to the Licensed
     Software or the Documentation, or any materials or services furnished or
     provided to Licensee under this Agreement. Specifically, Portal does not
     warrant that the Licensed Software will be error free or will perform in an
     uninterrupted manner. To the maximum extent allowed by law, Portal
     specifically disclaims all implied warranties of merchantability and
     fitness for a particular purpose (even if Portal had been informed of such
     purpose) with respect to the Licensed Software, Documentation and support
     and with respect to the use of any of the foregoing.

11   Limitation of liability

11.1 IN NO EVENT WILL PORTAL OR ITS SUBCONTRACTORS BE LIABLE FOR ANY LOSS OF
     PROFITS, LOSS OF USE, BUSINESS INTERRUPTION, LOSS OF DATA, COST OF COVER OR
     INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND IN
     CONNECTION WITH OR ARISING OUT OF THE FURNISHING, PERFORMANCE OR USE OF THE
     LICENSED SOFTWARE OR SERVICES PERFORMED HEREUNDER OR ANY DELAY IN DELIVERY
     OR FURNISHING THE LICENSED SOFTWARE OR SAID SERVICES WHETHER ALLEGED AS A
     BREACH OF CONTRACT OR TORTIOUS CONDUCT, INCLUDING NEGLIGENCE, EVEN IF
     PORTAL HAD BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

11.2 PORTAL'S MAXIMUM AGGREGATE LIABILITY FOR DAMAGES OR LOSS, HOWSOEVER ARISING
     OR CAUSED, WHETHER OR NOT ARISING FROM PORTAL'S NEGLIGENCE, SHALL IN NO
     EVENT BE GREATER THAN (A) IN THE EVENT SUCH DAMAGE IS NOT RELATED TO
     SUPPORT, THE LICENSE FEE SPECIFIED IN SCHEDULE A RELATED TO THE PARTICULAR
     LICENSED SOFTWARE PROGRAM WHICH CAUSED THE DAMAGE OR LOSS, OR (B) IN THE
     EVENT SUCH DAMAGE OR LOSS IS RELATED TO SUPPORT, THE SUPPORT FEES PAID BY
     LICENSEE FOR THE THEN CURRENT SUPPORT TERM.

                       PORTAL PROPRIETARY & CONFIDENTIAL


11.3 No employee, agent, representative or affiliate of Portal has authority to
     bind Portal to any oral representations or warranty concerning the Licensed
     Software. Any written representation or warranty not expressly contained in
     this Agreement is unenforceable.

12   AUDIT RIGHTS/QUARTERLY REPORTS

12.1 Licensee shall keep and maintain full and accurate records regarding its
     obligations under this Agreement and the number of Subscribers of the
     Licensed Software Database. Portal or its representatives shall be entitled
     to review and audit such books and records, no more often than once per
     year, and/or Licensee's compliance with the provisions of this Agreement
     from time to time during normal business hours by providing written notice
     to Licensee at least ten (10) business days prior to such audit. If any
     such audit reveals a deficiency in any amounts due to Portal hereunder,
     Licensee will immediately pay such amounts as are required to re-establish
     compliance with the terms of this Agreement.

12.2 Commencing on the third anniversary of the Effective Date, Licensee will
     provide Portal with annual reports setting forth the gross annual revenue
     (to be determined in accordance with GAAP) for Licensee and its Affiliates
     for the immediate preceding year and a reasonable description of any
     amounts owed to Portal under this Agreement.

13   ASSIGNMENT/BINDING AGREEMENT

13.1 Neither this Agreement nor any rights under this Agreement may be assigned
     or otherwise transferred by Licensee (by operation of law or otherwise), in
     whole or in part, without Portal's prior written consent. Notwithstanding
     the foregoing:

13.1.1 In the event that Licensee is acquired by a third party by way of merger,
       acquisition, or a sale of all or substantially all of Licensee's assets
       in one or more related transactions, but where there is no co-mingling of
       the assets of Licensee and the third party acquirer, such acquisition
       shall not be deemed a prohibited transfer or assignment and Licensee and
       its Affiliates shall have the right to continue using the Licensed
       Software as if no such transfer or assignment had occurred and the third
       party acquirer and its affiliates (excluding Licensee and its Affiliates)
       shall have no rights to use the Licensed Software.

13.1.2 Subject to Section 13.2 below, Licensee may assign this Agreement in its
       entirety to an Affiliate by providing written notice to Portal.

13.1.3 Subject to Sections 13.1.4, 13.1.5, and 13.2 below, Licensee may assign
       this Agreement in its entirety by way of merger, acquisition or sale of
       all or substantially all of its voting rights in one or more related
       transactions.

13.1.4 In the event of an assignment of this Agreement pursuant to Section
       13.1.3 above occurring within three years of the Effective Date, the
       number of Subscribers in the Licensed Software Database(s) shall be
       counted immediately prior to the assignment and the acquiring entity and
       the original VIA NET.WORKS Inc. Affiliates shall have a perpetual license
       for that number of Subscribers plus 10% (which number shall be
       distributed across the acquiring entity and the Affiliates). The annual
       maintenance Support Services fee for those Subscriber licenses shall be
       an amount equal to 20% of the aggregate license fees due or paid to
       Portal on the first day of the applicable annual maintenance Support
       Services term. During the six month period immediately following the
       assignment Portal will negotiate in good faith with the acquiring entity
       to determine the applicable future license and Support Services fees.

13.1.5 In the event of a transfer or assignment of this Agreement pursuant to
       Section 13.1.3 above occurring more than three years from the Effective
       Date, the acquiring entity and the original Affiliates shall be permitted
       to continue using the Licensed Software for up to six (6) months
       following the assignment provided such entity and Affiliates shall pay
       Portal all amounts (appropriately adjusted to reflect the six months of
       usage) that would have been owed by Licensee and its Affiliates had no
       assignment occurred. During the aforementioned six month period Portal
       will negotiate in good faith with the acquiring entity to determine the
       applicable future license and Support Services fees.

13.2 Notwithstanding the foregoing or anything else in this Agreement, no
     transfer or assignment of this Agreement shall be effective unless and
     until (i) the purported assignee/transferee becomes bound in writing to all
     of Licensee's obligations under this Agreement; (ii) Licensee must not be
     in default of any material provision of this Agreement, including without
     limitation any payment obligations hereunder, at the time of transfer or
     assignment. The license(s) transferred to the assignee/transferee shall be
     restricted to the continued operation of Licensee's original business and
     Application and shall not apply to other businesses of the
     assignee/transferee, even if such businesses are similar to or the same as
     the original Application. Further, the rights granted to Licensee with
     respect to its Affiliates shall not be applicable to the subsidiaries or
     affiliates of the assignee/transferee.

14   CONFIDENTIALITY

14.1 Each Party acknowledges that the Confidential Information constitutes
     valuable trade secrets and each party agrees that it shall use the
     Confidential Information of the other party solely in accordance with the
     provisions of this Agreement and it will not disclose, or permit to be
     disclosed, the same directly or indirectly, to any third party without the
     other party's prior written consent. Each party agrees to exercise due care

     permitted by and practical under the circumstances, Receiving Party
     provides to Disclosing Party prior notice of the intended disclosure and an
     opportunity to respond or object to the disclosure or if prior notice is
     not permitted or practical under the circumstances, prompt notice of such
     disclosure.

14.2 In the event of actual or threatened breach of the provisions of Section 3
     or Section 14, the non-breaching party will be entitled to immediate
     injunctive and other equitable relief, without bond and without the

           use its commercially reasonable, consistent with good business
           practice, to market and distribute the Software in the Territory.

     2.7   VIA NET.WORKS understands and agrees that the operation of the

           agreements with third parties with regard to such operating system

           rights underlying the Software.

          business transactions that relate to the required payments hereunder.
          VIA NET.WORKS hereby agrees to conduct its business (as it relates to
          VIA NET.WORKS performance of this Agreement) in such a manner as to
          reasonably facilitate the tracking

                                       12
<PAGE>

          and record keeping necessary to properly determine in an orderly and
          efficient manner all payments required hereunder.

          In the event that TRELLIX conducts or has conducted an examination,
          audit or inspection of records and, as a result of such examination,
          audit, or inspection of records, it is determined that there are
          unreported amounts payable to TRELLIX, such amounts shall be deemed to
          be payable when due and VIA NET.WORKS shall immediately pay to TRELLIX
          such payments and any interest due thereon.  In addition, if the
          unreported payments exceed fifteen percent (15%) of the amounts
          actually due, VIA NET.WORKS shall reimburse TRELLIX for its costs and
          expenses in conducting such examination, audit, inspection of records.

9.  INTELLECTUAL PROPERTY RIGHTS

    9.1   VIA NET.WORKS acknowledges that all right, title, and interest in and
          to the Software and any extensions or modifications created pursuant
          to this Agreement (including, without limitation, all rights under any
          applicable patents, copyrights, trademarks, trade secrets, and mask
          works) belongs to and shall remain the exclusive property of TRELLIX
          or its subsidiaries, affiliates or licensors.  To the extent permitted
          by applicable law, VIA NET.WORKS agrees that it shall not, either
          directly or indirectly, dispute or challenge the ownership or any such
          rights of TRELLIX, during or at any time after expiration or
          termination of this Agreement.

    9.2   VIA NET.WORKS agrees that it shall not alter, remove or conceal any
          copyright, trademark, trade name, or other proprietary rights or
          commercial markings which may appear on any copies of the Software.

    9.3   VIA NET.WORKS shall not, during or at any time after the expiration or
          termination of this Agreement, use or adopt any trademark, trade name
          or commercial designation that may be mistaken for or confused with
          the trademarks, trade names, and other proprietary rights or
          commercial markings of TRELLIX.

    9.4   VIA NET.WORKS shall not, either directly or indirectly, deposit or
          register the Software with any governmental agency or entity for any
          purpose or make any claim, whether in TRELLIX's name or otherwise,
          with any governmental agency or entity for copyright, trademark,
          patent, or any other form of intellectual property protection.

    9.5   VIA NET.WORKS at the expense of TRELLIX, use commercially reasonable
          effort to TRELLIX in maintaining the validity and enforceability of
          the intellectual property of TRELLIX during the term of this
          Agreement.

    9.6   VIA NET.WORKS and its affiliates shall not use any of the trademarks
          of TRELLIX in any manner that will prejudice their distinctiveness or
          validity, or otherwise affect the goodwill of any TRELLIX trademark.

10.  CONFIDENTIALITY AND NON-DISCLOSURE

     10.1  As used in this Section 10, the term "Confidential Information" shall
           mean any information disclosed by one party to the other pursuant to
           this Agreement which is in written, graphic, machine readable or
           other tangible form and is marked "Confidential", "Proprietary" or in
           some other manner to indicate its confidential nature. Confidential
           Information may also include oral information disclosed by one party
           to the other pursuant to this Agreement, provided that such
           information is designated as confidential at the time of disclosure
           and is reduced to writing by the disclosing party within a reasonable
           time (not to exceed thirty (30) days) after its oral disclosure, and
           such writing is marked in a manner to indicate its confidential
           nature and delivered to the receiving party. Notwithstanding the
           foregoing designation requirements, the source code underlying the
           Software shall be deemed to be Confidential Information of TRELLIX.
           VIA NET.WORKS and its affiliates shall also protect the
           confidentiality of any third party software contained in the Software
           in the same fashion that it is required to protect the Software
           itself.

     10.2  Each party shall treat as confidential all Confidential Information
           of the other party, shall not use such Confidential Information
           except as set forth herein, and shall not disclose such Confidential
           Information to any third party. Without limiting the foregoing, each
           of the parties shall use at least the same degree of care which it
           uses to prevent the disclosure of its own confidential information of
           like importance to prevent the disclosure of Confidential Information
           disclosed to it by the other party under this Agreement, provided,
           however, that in no event shall such degree of care be less than
           reasonable in light of general industry practice.

     10.3  Notwithstanding the foregoing, neither party shall have liability to
           the other with regard to any Confidential Information of the other
           which:

           (i)   was in the public domain at the time it was disclosed or
                    becomes in the public domain through no fault of the
                    receiver;

           (ii)  was known to the receiver, without restriction, at the time of
                    disclosure as shown by the files of the receiver in
                    existence at the time of disclosure;

           (iii) is disclosed with the prior written approval of the disclosure;

           (iv)  was independently developed by the receiver without any use of
                    the Confidential Information;

           (v)   becomes known to the receiver, without restriction, from a
                    source other than the discloser without breach of this
                    Agreement by the receiver; or

                                       14
<PAGE>

          (vi)  is disclosed pursuant to the order or requirement of a court,
                    administrative agency, or other governmental body, provided,
                    however, that the receiver shall provide prompt notice
                    thereof to enable the discloser to seek a protective order
                    to otherwise prevent such disclosure.

     10.4 Each party shall use all reasonable efforts, including, but not
          limited to, the execution of proprietary non-disclosure agreements
          with employees to enforce compliance with the provisions of this
          Section 10 by its directors, officers, employees, and any third party
          having access to the other party's Confidential Information.

     10.5 VIA NET.WORKS and its affiliates agree to notify TRELLIX promptly in
          writing of the existence of any circumstances surrounding unauthorized
          access, disclosure, distribution, possession, alteration, transfer,
          reproduction or use of the Software or any portions thereof.

     10.6 Each party agrees that in the event of any breach of this Section 10
          by the other party hereto, there shall be no adequate remedy at law
          and therefore such party shall be entitled to seek injunctive and/or
          other equitable relief, in addition to any other remedies afforded by
          law.

11.  INDEMNIFICATION

     11.1 TRELLIX shall defend, at its expense, VIA NET.WORKS and its affiliates
          from and against claims brought by third parties alleging that
          the Software infringes any (i) patent issued on or before the
          Effective Date, (ii) trademark issued on or before the Effective Date,
          (iii) copyright, or (iv) trade secret, and shall indemnify VIA
          NET.WORKS against all damages assessed against VIA NET.WORKS as part
          of a final judgment or settlement thereof. In addition, should the
          Software become, or in TRELLIX's opinion be likely to become, the
          subject of a claim of infringement, TRELLIX shall (a) obtain for VIA
          NET.WORKS the right to continue using the Software pursuant to the
          terms and conditions of this Agreement, (b) replace or modify the
          Software so that it becomes noninfringing but functionally equivalent,
          or if TRELLIX determines that neither of the foregoing is commercially
          reasonable, (c) provide for the return to VIA NET.WORKS of an amount
          equal to the fees paid by VIA NET.WORKS to TRELLIX for all copies of
          the Software subject to the claim of infringement, provided that VIA
          NET.WORKS and its affiliates returns to TRELLIX all such copies in its
          possession, upon which the licenses granted for the Software in this
          Agreement in the infringing jurisdiction shall terminate. Such
          indemnification obligation shall not apply to any claim based on (A)
          software not claimed to be owned or developed by or on behalf of
          TRELLIX, (B) the combination of the Software with other products not
          claimed to be owned or developed by or on behalf of TRELLIX, (C)
          software supplied by TRELLIX in accordance

                                       15
<PAGE>

          with VIA NET.WORKS designs, specifications, or instructions, or (D)
          arising from the failure of VIA NET.WORKS and its affiliates to use
          updated Software provided by TRELLIX for avoiding such infringement.

     11.2 If VIA NET.WORKS seeks indemnification pursuant to this Section 11
          from or against the assertion of any claim by a third person (a "Third
          Person Assertion"), it shall give prompt notice to TRELLIX, provided,
                                                                      --------
          however, that failure to give prompt notice will not relieve TRELLIX
          -------
          of any liability hereunder (except to the extent that TRELLIX has
          suffered actual material prejudice by such failure).

     11.3 Within ten (10) business days of receipt of notice from VIA NET.WORKS
          or its affiliates pursuant to Section 11.2 hereof, TRELLIX shall have
          the right, exercisable by written notice to VIA NET.WORKS, to assume
          the defense of a Third Person Assertion.  If TRELLIX assumes such
          defense, TRELLIX may select counsel, which shall be reasonably
          acceptable to VIA NET.WORKS.

     11.4 If TRELLIX (a) does not assume the defense of any Third Person
          Assertion in accordance with Section 11.3 hereof; (b) having so
          assumed such defense, unreasonably fails to defend against such Third
          Person Assertion; or (c) has been advised by the written opinion of
          counsel to VIA NET.WORKS that the use of the same counsel to represent
          both TRELLIX and VIA NET.WORKS would present a conflict of interest,
          then, upon ten (10) days' written notice to TRELLIX, VIA NET.WORKS may
          assume the defense of such Third Person Assertion.  In such event, VIA
          NET.WORKS shall be entitled under this Section 11 as part of its
          damages to indemnification for the costs of such defense.

     11.5 The party controlling the defense of a Third Person Assertion, will
          have the right to consent to the entry of judgment with respect to, or
          otherwise settle, such Third Person Assertion with the prior written
          consent of the other party, which consent shall not be unreasonably
          withheld.

     11.6 TRELLIX and VIA NET.WORKS (and each of its affiliates, as applicable)
          shall cooperate in the defense or prosecution of any Third Person
          Assertion.  TRELLIX or VIA NET.WORKS, as the case may be, shall have
          the right to participate, at its own expense, in the defense or
          settlement of any Third Person Assertion.

     11.7 THE FOREGOING STATES THE ENTIRE LIABILITY OF TRELLIX TO VIA NET.WORKS
          OR ANY OF ITS AFFILIATES AND ANY AND ALL THIRD PARTIES, WHETHER FOR
          DAMAGES OR OTHERWISE, FOR CLAIMS OF INFRINGEMENT OF ANY COPYRIGHT,
          PATENT, TRADEMARK, TRADE SECRET, OR OTHER INTELLECTUAL PROPERTY RIGHT.

     11.8 If a claim has been made that the Software infringes any (i) patent,
          (ii) trademark, (iii) copyright, or (iv) trade secret, and to the
          extent that

                                       16
<PAGE>

          TRELLIX is exposed to liability therefrom arising from VIA NET.WORKS
          continued use or distribution of the Software, TRELLIX may in its
          discretion terminate the rights and licenses granted hereunder with
          respect to the Software.

          obligations under this Agreement and shall indemnify TRELLIX against
          any loss or damage arising out of or in connection with any breach of
          the terms of this Agreement or any sublicense hereunder by any
          subsidiary of VIA NET.WORKS.

          compliance definition does not apply to the extent that the Software
          interoperates or exchange date-related data with other software,
          hardware, firmware, or data that is not Year 2000 compliant.


     13.2 THIRD PARTY HARDWARE WARRANTY: Any Third Party Hardware is subject to

                                  ARTICLE II

                              REGISTRATION RIGHTS

          2.1  Demand Registrations.
               --------------------

          (a)  Request for Registration.  At any time or times after the
               ------------------------
effective date of the first registration statement filed by the Company under
the Securities Act, the Initiating Holders may require that the Company effect a
registration under the Securities Act (i) in the case of a requested
registration on Form S-1 or any similar form (a "Long Form Registration"), with
                                                 ----------------------
respect to at least ten percent (10%) of the Registrable Securities then
outstanding, or (ii) in the case of a requested registration on Form S-3 or any
similar form, if available (a "Short-Form Registration"), with respect to
                               -----------------------
Registrable Securities with an anticipated offering price of $5,000,000 or more
(each a "Demand Registration"). Upon receipt of written notice of such demand,
         -------------------
the Company will promptly give written notice of the proposed registration to
all other holders of Registrable Securities and will include in such
registration all Registrable Securities specified in such demand, together with
all Registrable Securities of any other holder of Registrable Securities joining
in such demand as are specified in a written request received by the Company
within twenty (20) days after delivery of the Company's notice.

          (b)  Deferral of Demand Registration.  The Company shall file a
               -------------------------------
registration statement with respect to each Demand Registration requested
pursuant to Section 2.1 (a) as soon as practicable after receipt of the demand
of the Initiating Holders; provided, however, that if in the good faith judgment
of the Board of Directors of the Company, such registration would be seriously
detrimental to the Company in that such registration would interfere with a
proposed primary registration of securities by the Company or any other material
corporate transaction and the Board of Directors concludes, as a result, that it
is advisable to defer the filing of such registration statement at such time (as
evidenced by an appropriate resolution of the Board), then the Company shall
have the right to defer such filing for the period during which such
registration would be seriously detrimental; provided, however, that (x) the
Company may not defer the filing for a period of more than one hundred eighty
(180) days after receipt of the demand of the Initiating Holders, (ii) the
Company shall not exercise its right to defer a Demand Registration more than
once, and (iii) if the Company undertakes a primary registration following an
exercise of its deferral right, the holders of Registrable Securities shall have
"piggyback" rights under Section 2.2 hereof with respect to not less than one-
third (1/3) of the number of shares of Common Stock to be sold in such offering.

          (c)  Underwriting.  If the Initiating Holders intend to distribute the
               ------------
Registrable Securities covered by a Demand Registration by means of an
underwriting, they shall so advise the Company as a part of their demand made
pursuant to Section 2.1 and the Company shall include such information in its
written notice to holders of Registrable Securities. The Initiating Holders
shall have the right to select the managing underwriter(s) for an underwritten
Demand Registration, subject to the approval of the Company's Board of Directors
(which will not be unreasonably withheld or delayed). The right of any

                                       4
<PAGE>

holder of Registrable Securities to participate in an underwritten Demand
Registration shall be conditioned upon such holder's participation in such
underwriting in accordance with the terms and conditions thereof, and the
Company and such holders will enter into an underwriting agreement in customary
form.

          (d)  Priorities.  The holders of Registrable Securities will have
               ----------
absolute priority over any other securities included in a Demand Registration.
If other securities are included in any Demand Registration that is not an
underwritten offering, all Registrable Securities included in such offering
shall be sold prior to the sale of any of such other securities. If other
securities are included in any Demand Registration that is an underwritten
offering, and the managing underwriter for such offering advises the Company
that in its opinion the amount of securities to be included exceeds the amount
of securities which can be sold in such offering without adversely affecting the
marketability thereof, the Company will include in such registration all
Registrable Securities requested to be included therein prior to the inclusion
of any other securities. If the number of Registrable Securities requested to be
included in such registration exceeds the amount of securities which in the
opinion of such underwriter can be sold without adversely affecting the
marketability of such offering, such Registrable Securities shall be included
pro rata among the holders thereof based on the percentage of the outstanding
Common Stock held by each such Stockholder (assuming the conversion of the
Convertible Preferred and the exercise of all options, warrants and similar
rights held by such Stockholder).

          2.2  Piggyback Registrations
               -----------------------

          (a)  Request for Inclusion.  If the Company shall determine to
               ---------------------
register any of its securities for its own account or for the account of other
security holders of the Company on any registration form (other than Form S-4 or
S-8) which permits the inclusion of Registrable Securities (a "Piggyback
                                                               ---------
Registration"), the Company will promptly give each holder of Registrable
- ------------
Securities written notice thereof and, subject to Section 2.2(c), shall include
in such registration all the Registrable Securities requested to be included
therein pursuant to the written requests of holders of Registrable Securities
received within twenty (20) days after delivery of the Company's notice.

          (b)  Underwriting.  If the Piggyback Registration relates to an
               ------------
underwritten public offering, the Company shall so advise the holders of
Registrable Securities as a part of the written notice given pursuant to Section
2.2(a). In such event, the right of any holder of Registrable Securities to
participate in such registration shall be conditioned upon such holder's
participation in such underwriting in accordance with the terms and conditions
thereof. All holders of Registrable Securities proposing to distribute their
securities through such underwriting shall (together with the Company) enter
into an underwriting agreement in customary form with the representative of the
underwriter or underwriters selected by the Company.

          (c)  Priorities.  If such proposed Piggyback Registration is an
               ----------
underwritten offering and the managing underwriter for such offering advises the
Company that the securities requested to be included therein exceeds the amount
of securities that can be sold in such offering without adversely affecting the
marketability thereof, except as provided in Section 2.1(b), any securities to
be sold by the Company in such offering shall have priority over any Registrable
Securities, and the Registrable Securities to be sold in such

                                       5
<PAGE>

offering shall have priority over any other securities. In the event that less
than all the Registrable Securities proposed to be sold are included in such
registration as a result of the priorities set forth in this Section 2.2(c), the
number of shares to be included by a holder of Registrable Securities in such
registration shall be reduced pro rata on the basis of the percentage of the
outstanding Common Stock held by such Stockholder (assuming the conversion of
the Convertible Preferred and the exercise of all options, warrants and similar
rights held by such Stockholder) and all other holders exercising similar
registration rights. The Company shall not grant any registration rights that
entitle the holders of other securities to any priority over the Registrable
Securities in any Piggyback Registration without the prior consent of the
holders of a majority or more of the then-outstanding Registrable Securities.

          2.3  Expenses of Registration.  All Registration Expenses incurred in
               ------------------------
connection with up to two Long-Form Registrations and all Short-Form and
Piggyback Registrations shall be borne by the Company; provided, however, that
(x) no registration shall count as one of the Company-paid Long Form
Registrations unless the holders of Registrable Securities are able to register
and sell at least 90% of the Registrable Securities requested to be included
therein, and (y) the holders of Registrable Securities shall be entitled to
additional Long-Form Registrations so long as such holders agree to bear all
Registration Expenses associated therewith. All Selling Expenses relating to
Registrable Securities included in any Demand or Piggyback Registration shall be
borne by the holders of such securities pro rata on the basis of the number of
shares sold by them.

          2.4  Registration Procedures.  In the case of each registration
               -----------------------
effected by the Company pursuant to this Article II, the Company will keep each
holder of Registrable Securities advised in writing as to the initiation of such
registration and as to the completion thereof. At its expense, the Company will
use its best efforts to:

          (a)  cause such registration to be declared effective by the
Commission and, in the case of a Demand Registration, keep such registration
effective for a period of one hundred eighty (180) days or until the holders of
Registrable Securities included therein have completed the distribution
described in the registration statement relating thereto, whichever first
occurs;

          (b)  prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement (including post-effective amendments) as may be
necessary to comply with the provisions of the Securities Act with respect to
the disposition of all securities covered by such registration statement;

          (c)  obtain appropriate qualifications of the securities covered by
such registration under state securities or "blue sky" laws in such
jurisdictions as may be requested by the holders of Registrable Securities;
provided, however, that the Company shall not be required to file a general
consent to service of process in any jurisdiction in which it is not otherwise
subject to service in order to obtain any such qualification;

                                       6
<PAGE>

          (d)  furnish such number of prospectuses and other documents incident
thereto, including any amendment of or supplement to the prospectus, as a holder
of Registrable Securities from time to time may reasonably request;

          (e)  notify each holder of Registrable Securities covered by such
registration statement, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or incomplete in the light of the
circumstances then existing, and at the request of any such holder, prepare and
furnish to such holder a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such shares, such prospectus shall not include an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading or
incomplete in the light of the circumstances then existing;

          (f)  cause all Registrable Securities covered by such registration to
be listed on each securities exchange or inter-dealer quotation system on which
similar securities issued by the Company are then listed;

          (g)  provide a transfer agent and registrar for all Registrable
Securities covered by such registration and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration;

          (h)  otherwise comply with all applicable rules and regulations of the
Commission, and make available to its security holders, as soon as reasonably
practicable, an earnings statement covering the period of at least twelve
months, but not more than 18 months, beginning with the first month after the
effective date of the registration statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act; and

          (i)  in connection with any underwritten Demand Registration, the
Company will enter into an underwriting agreement reasonably satisfactory to the
Initiating Holders containing customary underwriting provisions, including
indemnification and contribution provisions.

          2.5  Indemnification.
               ---------------

          (a)  The Company will indemnify each holder of Registrable Securities,
each of such holder's officers, directors, partners, agents, employees and
representatives, and each person controlling such holder within the meaning of
Section 15 of the Securities Act, with respect to each registration,
qualification or compliance effected pursuant to this Article II, against all
expenses, claims, losses, damages and liabilities (or actions, proceedings or
settlements in respect thereof) arising out of or based on any untrue statement
(or alleged untrue statement) of a material fact contained in any prospectus,
offering circular or other

                                       7
<PAGE>

document (including any related registration statement, notification or the
like) incident to any such registration, qualification or compliance, or based
on any omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
or any violation by the Company of the Securities Act or any rule or regulation
thereunder applicable to the Company and relating to action or inaction required
of the Company in connection with any such registration, qualification or
compliance, and will reimburse each such indemnified person for any legal and
any other expenses reasonably incurred in connection with investigating and
defending or settling any such claim, loss, damage, liability or action;
provided, however, that the Company will not be liable in any such case to the
extent that any such claim, loss, damage, liability or expense arises out of or
is based on any untrue statement or omission based upon written information
furnished to the Company by such holder of Registrable Securities and stated to
be specifically for use therein. It is agreed that the indemnity agreement
contained in this Section 2.5(a) shall not apply to amounts paid in settlement
of any such loss, claim, damage, liability or action if such settlement is
effected without the consent of the Company (which consent has not been
unreasonably withheld).

          (b)  Each holder of Registrable Securities included in any
registration effected pursuant to this Article II shall indemnify the Company,
each of its directors, officers, agents, employees and representatives, and each
person who controls the Company within the meaning of Section 15 of the
Securities Act, each other participating holder of Registrable Securities and
each of their officers, directors and partners, and each person controlling such
holders, against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse
such indemnified persons for any legal or any other expenses reasonably incurred
in connection with investigating or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in strict conformity with written
information furnished to the Company by such holder of Registrable Securities;
provided, however, that (x) no holder of Registrable Securities shall be liable
hereunder for any amounts in excess of the net proceeds received by such holder
pursuant to such registration, and (y) the obligations of such holder of
Registrable Securities hereunder shall not apply to amounts paid in settlement
of any such claims, losses, damages or liabilities (or actions in respect
thereof) if such settlement is effected without the consent of such holder
(which consent has not been unreasonably withheld).

          (c)  Each party entitled to indemnification under this Section 2.5
(the "Indemnified Party") shall give notice to the party required to provide
      -----------------
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
                      ------------------
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom through counsel approved by the Indemnified Party
(whose approval shall not unreasonably be withheld), and the Indemnified Party
may participate in such defense at such party's expense; provided, however, that
the failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations under this Section 2.5 to the
extent such failure is not prejudicial. No Indemnifying Party in the defense of
any such claim or litigation shall, except with the consent of each Indemnified
Party, consent to entry of any judgment or enter into any settlement which does

                                       8
<PAGE>

not include an unconditional release of such Indemnified Party from all
liability in respect to such claim or litigation. Each Indemnified Party shall
furnish such information regarding itself or the claim in question as an
Indemnifying Party may reasonably request in writing and as shall be reasonably
required in connection with defense of such claim and litigation resulting
therefrom.

          (d)  If the indemnification provided for in this Section 2.5 is held
by a court of competent jurisdiction to be unavailable to an Indemnified Party
with respect to any loss, liability, claim, damage or expense referred to
therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified
Party hereunder, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such loss, liability, claim, damage or expense
in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party on the one hand and of the Indemnified Party on the other in
connection with the statements or omissions which resulted in such loss,
liability, claim, damage or expense as well as any other relevant equitable
considerations. The relative fault of the Indemnifying Party and of the
Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
Indemnifying Party or by the Indemnified Party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. Notwithstanding the foregoing, no holder of Registrable
Securities shall be required to contribute amounts in excess of the amounts that
such holder would have been required to pay pursuant to the indemnification
provisions of this Section 2.5 (assuming such provisions were enforceable).

          (e)  Notwithstanding the foregoing, to the extent that the provisions
on indemnification and contribution contained in an underwriting agreement
entered into in connection with an underwritten public offering are in conflict
with the foregoing provisions, the provisions in the underwriting agreement
shall control.

          2.6  Other Obligations.  With a view to making available the benefits
               -----------------
of certain rules and regulations of the Commission that may effectuate the
registration of Registrable Securities or permit the sale of Registrable
Securities to the public without registration, the Company agrees to:

          (a)  after its initial registration under the Securities Act, exercise
best efforts to cause the Company to be eligible to utilize Form S-3 (or any
similar form) for the registration of Registrable Securities;

          (b)  at such time as any Registrable Securities are eligible for
transfer under Rule 144(k), upon the request of the holder of such Registrable
Securities, remove any restrictive legend from the certificates evidencing such
securities at no cost to such holder;

          (c)  make and keep available public information as defined in Rule 144
under the Securities Act at all times from and after ninety (90) days following
its initial registration under the Securities Act;

                                       9
<PAGE>

          (d)  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;

          (e)  furnish any holder of Registrable Securities upon request a
written statement by the Company as to its compliance with the reporting
requirements of Rule 144 (at any time from and after ninety (90) days following
the effective date of the first registration statement filed by the Company for
an offering of its securities to the general public), and of the Securities Act
and the Exchange Act (at any time after it has become subject to such reporting
requirements), a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents as a holder of Registrable
Securities may reasonably request in availing itself of any rule or regulation
of the Commission (including Rule 144A) allowing a holder of Registrable
Securities to sell any such securities without registration.

          2.7  Hold-Back Agreements.  If requested by the Company or any
               --------------------
underwriter of Common Stock of the Company, a holder of Registrable Securities
shall not sell or otherwise transfer or dispose of any Common Stock (other than
pursuant to such registration) during (a) in the case of the Company's initial
public offering of Common Stock for its own account, the one hundred eighty
(180) day period following the effective date of such registration statement,
and (b) in the case of all subsequent registrations of the Company's Common
Stock, the ninety (90) day period following the effective date of such
registration statement; provided, however, that if holders of Management Stock
are subjected to hold-back restrictions of shorter duration, such shorter
periods shall apply to holders of Registrable Securities. The obligations
described in this Section 2.7 shall not apply to a registration on Form S-4 or
Form S-8 or similar forms which may be promulgated in the future and, except in
the case of the Company's initial public offering, shall not apply to a holder
of Registrable Securities representing less than one percent (1%) of the then-
outstanding Common Stock.

          2.8  Termination of Registration Rights.  The right of any holder of
               ----------------------------------
Registrable Securities to request inclusion of Registrable Securities in any
registration pursuant to this Article II shall terminate when (i) all
Registrable Securities beneficially owned by such holder of Registrable
Securities may immediately be sold under Rule 144(k), and (ii) the Company's
Common Stock is listed on a national securities exchange or traded in The Nasdaq
Stock Market; provided, however, that the provisions of this Section 2.8 shall
not apply to any holder of Registrable Securities representing more than two
percent (2%) of the then-outstanding Common Stock.

                             TRANSFER RESTRICTIONS

          3.1  Prohibition on Transfer.  No Stockholder shall sell, transfer,

assign, pledge or otherwise dispose of any interest in any Common Stock (a
"Transfer") other than in compliance with this Article III. Each Stockholder

agrees not to consummate any Transfer (other than a Transfer to a Permitted
Transferee pursuant to Section 3.4) until the expiration of a 30-day period (the
"Election Period") following

delivery by such Stockholder of a Sale Notice pursuant to Section 3.2 or an
Offer Notice pursuant to Section 3.3, as applicable.

          3.2  Right of First Refusal.  If at any time a Management Holder
               ----------------------
receives a bona fide offer from any person to purchase shares of Common Stock
held by such Management Holder (a "Third-Party Offer"), such Management Holder
                                   -----------------
shall cause such Third-Party Offer to be reduced to writing and shall notify the
Company and each holder of Investor Stock of such Management Holder's desire to
accept the Third-Party Offer.  The Management Holder's notice (the "Sale
                                                                    ----
Notice") shall contain an irrevocable offer to sell such Common Stock to the
- ------
Company at a purchase price equal to the price contained in, and on the same
terms and conditions of, the Third-Party Offer and shall be accompanied by a
true copy of the Third-Party Offer (which shall identify the offeror).  At any
time within 20 days after the date of receipt by the Company of the Sale Notice,
the Company shall have the right, exercisable by delivery of written notice to
the transferring Stockholder, to purchase all or any portion of the Common Stock
covered by the Sale Notice at the same price and on the same terms and
conditions as the Sale Notice.  In the event that the Company does not elect to
acquire all of the Common Stock specified in the Sale Notice, each holder of
Investor Stock shall have the right, exercisable by delivery of written notice
to the transferring Stockholder prior to the expiration of the Election Period,
to purchase all or any portion of its pro rata share (equal to such electing
Stockholder's percentage interest in the outstanding Investor Stock) of the
remaining shares covered by the Sale Notice.  The Company or the holders of
Investor Stock may pay cash to the selling Management Holder equal in amount to
the fair market value of any non-cash consideration offered in the Third-Party
Offer.  If the Company and/or the holders of Investor Stock have not notified
the selling Management Holder in writing of their election to purchase all
shares of such Common Stock as set forth herein prior to the expiration of the
Election Period, the selling Management Holder may within 60 days thereafter
sell the balance of such Common Stock not purchased by the Company and/or the
holders of Investor Stock on the terms set forth in the original Third-Party
Offer.  Any Management Stock covered by the Third Party Offer that is not so
transferred during such 60-day period shall again be subject to this Section
3.2.

          3.3  Right of First Offer.  Prior to any Transfer of Investor Stock,
               --------------------
the transferring Stockholder shall deliver a written notice (the "Offer Notice")
                                                                  ------------
to the Company and the other holders of Investor Stock disclosing in reasonable
detail the number of shares of Investor Stock proposed to be transferred (the
"Offered Shares") and the terms and conditions of such proposed Transfer.  Each
- ---------------
other holder of Investor Stock shall have the right, exercisable by delivery of
written notice to the transferring Stockholder within 20 days after delivery of
the Offer Notice, to purchase all (but not less than all) of its pro rata share
(equal to such electing holder's percentage interest in the outstanding Investor
Stock) of the Offered Shares on the terms and conditions set forth in the Offer
Notice.  In the event that any holder of Investor Stock declines to exercise its
right of first offer, the remaining unpurchased portion of the Offered Shares
shall be reoffered to the electing holders of Investor Stock on a pro rata basis
until the expiration of the Election Period.  To the extent that the holders of
Investor Stock have not elected to purchase all of the Offered Shares prior to
the expiration of the Election Period, the transferring Stockholder may, within
90 days after the expiration of the Election Period, Transfer such Offered
Shares to one or more third parties at a price not less than 95% of the price
per share specified in the Offer Notice.  Any Offered Shares not transferred
during such 90-day period shall again be subject to the provisions of this
Section 3.3 upon subsequent Transfer.

          3.4  Exempt Transactions.  The restrictions set forth in this Article
               -------------------
III shall not apply to Transfers of Management Stock or Investor Stock to a
Permitted Transferee of the transferring Stockholder; provided, however, that
such Permitted Transferee shall agree in writing to be bound by such
restrictions in connection with subsequent Transfers.

          3.5  Repurchase Restrictions.  In the event of termination of a
               -----------------------
Management Holder's employment with the Company and its subsidiaries for any
reason, the Company shall have the right, exercisable by written notice to the
Management Holder at any time prior to the expiration of a 30-day period
following such termination of employment, to repurchase all or any portion of
the Management Stock held by such Management Holder and its Permitted
Transferees at a cash price per share equal to the fair market value of the
Common Stock as determined in good faith by the Company's Board of Directors as
of the date of termination or, in the case of Management Stock that is subject
to vesting or similar restrictions at the time of termination, at the Management
Holder's original purchase price for such shares of Management Stock.  The
closing of the repurchase of Management Stock shall occur within 90 days of
termination of the Management Holder's employment or such longer period of time
determined by the Company in good faith to be necessary to avoid the loss of
"qualified small business stock" treatment under Section 1202 of the Internal
Revenue Code for any Stockholder other than the terminated Management Holder.

representing at least five percent (5%) of the fully-diluted Common Stock (a
"Significant Holder"), to visit and inspect any of the properties of the
Company, including its books of account and other records (and make copies
thereof and take extracts therefrom), and to discuss its affairs, finances and

prohibited from using any such information for the sole purpose of generating

          4.3   Prompt Payment of Taxes, etc. The Company will promptly pay and
                -----------------------------
discharge, or cause to be paid and discharged, when due and payable, all lawful

proceedings and if the Company shall have set aside on its books adequate
reserves with respect thereto; and provided, further, that the Company will pay
all such taxes, assessments, charges or levies forthwith upon the commencement
of proceedings to foreclose any lien which may have attached as security

needful and proper repairs, renewals, replacements, additions and improvements
thereto; and the Company and its subsidiaries will at all times comply with each
material provision of all leases to which any of them is a party or under which
any of them occupies property if the breach of such provision might have a
material and adverse effect on the condition, financial or otherwise, or
operations of the Company.

          4.5   Insurance.  The Company will keep its assets and those of its
                ---------
subsidiaries which are of an insurable character insured by financially sound

customarily insured against by companies in the Company's line of business, and
the Company will maintain, with financially sound and reputable insurers,

          4.7   Independent Accountants.  The Company will retain a "Big Five"
                -----------------------
national accounting firm as its independent public accountants who shall certify
the Company's financial statements at the end of each fiscal year.  In the event
the services of the independent public accountants so selected are terminated,

to the Investors a letter from such firm setting forth the reasons for the
termination of their services. In the event of such termination, the Company
will promptly thereafter engage another "Big Five" national accounting firm as
its independent public accountants. In its notice to the holders of Investor
Stock the Company shall state whether the change of accountants was recommended
or approved by the Board of Directors of the Company or any committee thereof.

          4.8   Compliance with Laws. The Company and all its subsidiaries shall

trademarks, trade names or copyrights owned or possessed by it or any subsidiary
and deemed by the Company to be necessary to the conduct of their business.

          4.10  Preemptive Rights. In the event that the Company proposes to
                -----------------
issue any Common Stock or any other equity securities, the Company shall give
not less than 30 days' prior written notice to the Investors setting forth the
terms and conditions of such proposed issuance (the "Issuance Notice").  The
                                                     ---------------
Investors shall have the preemptive right to purchase up to 80% of the
securities so offered on the terms and conditions set forth in the Issuance
Notice by giving written notice to the Company within fifteen days after receipt
of the Issuance Notice (the "Preemptive Election Period").  Each electing
                             --------------------------
Investor shall have the right to purchase all or any portion of its pro rata
share of the offered securities (determined by dividing such Investor's
percentage interest in the Common Stock on a fully-diluted basis by the
aggregate percentage interest of all electing Investors and multiplying such
quotient by 80% of the offered securities); provided, however, that if any
Investor declines to exercise its preemptive right in full, the remaining
electing Investors shall be entitled to purchase such Investor's unpurchased
portion of the offered securities on a pro rata basis. The Company may issue and
sell all offered securities not purchased by the Investors on the terms and
conditions set forth in the issuance Notice within 90 days after the expiration
of the Preemptive Election Period; provided, however, that any offered
securities not sold within such 90 day period or any offered securities that are
proposed to be sold on terms and conditions less favorable to the Company than
those set forth in the Issuance Notice shall again be subject to the procedure
set forth in this Section 4.10 prior to issuance.  The provisions of this
Section 4.10 shall not apply to any Permitted Issuance (as defined in Section 6
of Article Four of the Company's Certificate of Incorporation, as amended) or
any issuance of equity securities for non-cash consideration to non-Affiliates
of the Company.  For purposes of this Section 4.10, an Investor and its
Affiliates shall be deemed to be one person, and an Investor may assign its
rights pursuant to this Section 4.10 to one or more of such Affiliates, subject
only to compliance with applicable securities laws.

          4.11  Directed Share Program.  In connection with the Company's
                ----------------------
initial public offering of Common Stock, to the extent permitted by applicable
laws and the rules and regulations of the Commission, the Company will set aside
not less than 5.0% of the securities proposed to be offered to the public for
purchase by holders of Investor Stock, which holders shall be entitled to
subscribe for such

                                       15
<PAGE>

securities on a pro rata basis (determined by dividing each participating
holder's percentage interest in the fully-diluted Common Stock by the aggregate
percentage interest of all participating holders).

          4.12   Issuance of Management Stock.   The Company shall not issue
                 ----------------------------
any shares of Common Stock to its officers or employees unless such persons
agree in writing to be bound by the provisions hereof as a Management Holder.

          4.13   Investment Company Act.  The Company shall conduct its
                 ----------------------
operations such that it does not become subject to regulation as an "investment
company" as that term is defined in the Investment Company Act of 1940, as
amended, and the rules and regulations of the Commission thereunder.

          6.1  Governing Law.  This Agreement shall be governed in all respects
               -------------

preferences of the security or interest" of such holder, as such terms are used
in Section 225.2(q)(2)(i) of Regulation Y of the Board of Governors of the
Federal Reserve System or (ii) if the requirement for such vote or consent would
be to cause the shares of Series B-2 Preferred or Series C-2 Preferred held by

          6.5   Delays or Omissions.  No delay or omission to exercise any
                -------------------
right, power or remedy accruing to any Stockholder under this Agreement shall
impair any such right, power or remedy of such Stockholder nor shall it be
construed to be a waiver of any such breach or default, or an acquiescence
therein, or of or in any similar breach or default thereafter occurring; nor
shall any waiver of any single breach or default be deemed a waiver of any other
breach or default theretofore or thereafter occurring. Any waiver, permit,
consent or approval of any kind or character on the part of any Stockholder of
any breach or default under this Agreement or any waiver on the part of any
Stockholder of any provisions or conditions of this Agreement must be made in
writing and shall be effective only to the extent specifically set forth in such
writing.  All remedies, either under this Agreement or by law or otherwise
afforded to any Stockholder, shall be cumulative and not alternative.

          6.6   Severability. Unless otherwise expressly provided herein, a
                ------------
Stockholder's rights hereunder are several rights, not rights jointly held with
any of the other Stockholders.  In case any provision of the Agreement shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

          6.7   Counterparts.  This Agreement may be executed in any number of
                ------------
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

          6.8   Termination.  The provisions of this Agreement (other than
                -----------
Article II hereof) shall terminate upon consummation of a Qualified Public
Offering.  The provisions of Article II shall terminate on the tenth anniversary
of the date hereof.

          6.9   Specific Enforcement.  Any holder of Investor Stock shall be
                --------------------
entitled to specific enforcement of its rights under this Agreement.  The
parties acknowledge that money damages would be an inadequate remedy for a
breach of this Agreement and consent to an action for specific performance or
other injunctive relief in the event of any such breach.

    Customer support available 24 hours per day, 365 days per year. Colocation
    space for one rack at Verio's POP location at 60 Hudson, New York

    (additional terms to be defined.)
    No local loops required. This is a local interconnect at 60 Hudson between

    Customer will provide, at its cost, a DS3 interface on its router at 60
    Hudson for the Verio IP connection.

8)  Service Date:  Will enter date as soon as one is available from Qwest.

9)  Fees and Charges:

    a)   One time fees:

         Installation and startup fee for DS3 interface:      $2,000

         Colocation installation and startup:                 $1,000

    b)   Monthly recurring fees:

         IP charges are based on measured usage of the interface.

         Verio will sample the traffic level on the interface no less frequently
         than once every 5 minutes. Traffic level is determined by the maximum
         of the input or output level on the interface. Measured usage is the
         traffic level under which 95% of samples fall over each calendar month.

         If Customer orders a second Verio connection at a different Verio
         backbone location, this price will apply to the sum of the measured
         usage for the two locations, with each location being separately
         measured as above.

         Minimum monthly fee for IP services is $3,300 per month. Services will
         be billed monthly in arrears and will be based on the prior month's
         actual usage.

10) Term Commitment:  36 months from the Commencement Date (defined below).

12) Other Terms and Conditions

    a)   Customer Obligations: Customer shall be responsible for providing and
         --------------------
         maintaining, at Customer's cost, all equipment and space, conduit,
         electrical power and environmental conditions required to enable VERIO
         to offer the Services. Customer shall also be responsible for
         provisioning local loops, unless VERIO has specifically agreed to
         provide local loops as noted in paragraph (7) above. VERIO has no
         responsibility for Customer provided equipment and/or facilities. In
         the event that Customer's equipment and/or facilities impair Customer's
         use of the Services, Customer shall nevertheless be liable for payment
         for the Services. In addition, should Customer's use of or failure to
         maintain its equipment and/or facilities cause or be likely to cause in
         VERIO'S reasonable judgment hazard, interference or obstruction of
         VERIO's or its suppliers' networks or services, VERIO shall be entitled
         to terminate or suspend the Services.

    b)   Fees and Payment: Customer shall pay the fees and other charges
         ----------------
         ("Service charges") set forth in Paragraph (9) for each Service as
         provided in this Agreement. Billing for transport services shall
         commence on the later of the Service Date, or the date that VERIO can
         provide end to end connectivity ("Commencement Date"). In the event
         that VERIO has failed to deliver the Services within forty-five (45)
         days of the Service Date (other than as the result of a failure by
         Customer to meet its obligations under Paragraph 12(a) or Customer's
         failure to accept installation of the Services), Customer may, as its
         sole and exclusive remedy for VERIO's failure to provide the Services,
         terminate this Agreement. Service charges shall be invoiced monthly in
         advance, unless otherwise agreed, and payment shall be due on the date
         specified in the invoice ("Due Date"). Set-Up charges shall be invoiced
         upon installation of Services by VERIO. Customer shall pay a late
         payment charge equal to 1.5% (or the highest amount permitted by law,
         whichever Is lower) per month or portion thereof on the outstanding
         balance of any invoice remaining unpaid thirty (30) days after the Due
         Date. Customer's failure to pay the invoiced amount in full by the end
         of the thirty (30) day period shall entitle VERIO to suspend or
         terminate the Services. Such suspension or termination shall not
         relieve Customer of its obligation to pay the Service charges. Customer
         agrees to pay VERIO its reasonable expenses, including attorney's fees
         and collection agency fees, incurred in enforcing VERIO's rights under
         this Agreement. Customer shall pay all federal, state, and local sales,
         use, value added, excise, duty and any other taxes assessed with
         respect to the Services, except taxes based on VERIO's net income. In
         addition,
<PAGE>

         Customer may also be required to pay telco installation and
         recurring fees, domain name registration fees, and other equipment
         costs. All payments shall be in U.S. dollars.

    c)   Customer Representations and Warranties: Customer represents and
         ---------------------------------------
         warrants that: i) Customer has received all necessary permits, licenses
         approvals and grants necessary to carry out the businesses in which
         Customer is engaged; ii) Customer has complied and will comply for the
         term of this Agreement with all laws, regulations, orders and statues
         which may be applicable to Customer. A breach by Customer of this
         paragraph 12(c) shall entitle VERIO to immediately terminate this
         Agreement.

    d)   Use of Services: Customer shall use and permit the use of the Services
         ---------------
         solely for provision by Customer of data services, and not for the
         provision of telephony services. Customer shall ensure that the
         Services are not used for any unlawful purposes, or in violation of any
         applicable law, regulation, order or statute. Customer's use of the
         Services shall i) not interfere with or impair service over VERIO's or
         its suppliers' networks or facilities; ii) impair privacy of any
         communications over such networks or facilities; iii) cause damage of
         any nature to VERIO's or its suppliers' assets. Customer shall at all
         times adhere and shall ensure that its customers and authorized users
         shall adhere to the VERIO Acceptable Use Policy located at
         http://www.verio.net/isite/policy.html as amended from time to time by
         --------------------------------------
         VERIO, with amendments becoming effective upon posting of the revised
         policy at the URL. A breach by Customer of this paragraph 12(d) shall
         entitle VERIO to take immediate corrective action, including
         disconnection or discontinuance of any and all service, and/or
         termination of this Agreement.

    e)   Term and Termination: This Agreement shall commence on the date hereof
         --------------------
         and continue through the end of the Term Commitment. This Agreement
         shall be automatically renewed on a month to month basis at the end of
         the Term Commitment until terminated by either party on sixty (60) days
         prior written notice to the other party. This Agreement may be
         terminated by either party if (i) the other party is in breach or
         default of any term of this Agreement and fails to cure such breach or
         default within thirty (30) days from the date of written notice
         specifying such breach or default or (ii) the other party becomes
         insolvent, fails to pay its debts as they become due, or becomes the
         subject of any proceeding in bankruptcy, liquidation, dissolution,
         receivership, attachment, or composition or general assignment for the
         benefit of creditors. In the event that this agreement is terminated by
         VERIO as provided in Paragraphs 12(a), (c), (d), or (e) by Customer
         (other than for a breach of this Agreement by VERIO) prior to the end
         of the Term Commitment, Customer will be required to pay for each month
         remaining in the Term Commitment either i) for fixed rate contracts,
         75% of VERIO's standard monthly charge, or ii) for burst transit
         contracts, 40% of the full utilization rate for the circuit. Customer
         will also be required to pay to VERIO any charges or costs incurred by
         VERIO in terminating local loop facilities (if any) provided by VERIO
         hereunder. VERIO reserves the right to change the rates it charges for
         Services at the end of the Term Commitment. VERIO will provide sixty

         POSSIBLITY OF SUCH DAMAGES) TO THE OTHER PARTY OR ANY THIRD PARTY, IN
         CONNECTION WITH THE SERVICES OR OTHER MATTERS COVERED BY THIS
         AGREEMENT, WHETHER SUCH CLAIM IS BASED ON AN ACTION IN CONTRACT OR TORT
         OR STRICT LIABILITY OR OTHER LEGAL THEORY. With the exception of any
         indemnity obligation or a breach of paragraph (l) below, in no event
         shall either party's liability for any damages, losses and causes of
         actions whether in contract or tort (including negligence or otherwise)

         Services which gave rise to such damages, losses and causes of actions
         during the 12-month period prior to the date the damage or loss
         occurred or the cause of action arose. Neither party shall be liable
         for failure or delay in performing its obligations hereunder if such

         including, without limitation, acts of any governmental body, war,
         insurrection, sabotage, embargo, fire, flood, strike or other labor
         disturbance, interruption of or delay in transportation, interruption

         notice to VERIO terminate this Agreement without any further liability
         to VERIO, apart from the obligation to pay for Services rendered to the
         date of the termination. For the purposes of this paragraph (j),
         "Interruption" means a service outage that is not due to scheduled
         maintenance or to any action or inaction on the part of Customer.

    k)   Miscellaneous: The validity, interpretation, enforceability, and

         failure to exercise and no delay in exercising any right, remedy, or
         power hereunder shall operate as a waiver thereof, nor shall any single
         or partial exercise of any right, remedy, or power hereunder preclude
         any other or further exercise thereof or the exercise of any other
         right, remedy, or power provided herein or by law or in equity. The
         waiver by any party of the time for performance of any act or condition
         hereunder shall not constitute a waiver of the act or condition itself.

         parties and their respective successors, and permitted assigns.
         Customer may not assign this Agreement without the prior written

         is acknowledged by the recipient) to the addresses set forth in
         Paragraphs (1) and (2) above, or such other addresses as may be
         notified by the parties. Any notice or request shall be deemed given on
         the date of delivery.

    l)   Confidentiality: Each party agrees to keep confidential and to use only

         disclosed pursuant to this Agreement which is appropriately marked as
         confidential or which would reasonably be considered to be of a
         confidential nature ("Confidential Information") and (ii) the terms of
         this Agreement and all negotiations relating thereto. The obligation of
         confidentiality shall not apply to information which is publicly
         available through authorized disclosure, is known by the receiving
         party at the time of disclosure as evidenced by a writing in the
         possession of the receiving party at the time of disclosure, is
         rightfully obtained from a third party who has the right to disclose
         it, or which is required by law to be disclosed. Upon any termination
         of this Agreement, the receiving party shall return all Confidential
         Information of the disclosing party, and all copies thereof, in the
         possession or control of the receiving party.

    m)   Entire Agreement: This agreement supersedes all previous
         ----------------
         representations, understandings or agreements and shall prevail
         notwithstanding any variance with the terms and conditions of any order
         submitted by Customer.
