OUR BUSINESS

    We are an Internet network providing country-specific and regional content
for Spanish- and Portuguese-speaking audiences in Latin America and the United
States. Recognizing that the countries in the Americas are diverse, we have
designed our network to consist of country Websites as well as a global Website.
We currently have country Websites for, and sales and content production offices
in, Argentina, Brazil, Mexico, the United States and Uruguay. We plan to
establish sales and content production offices in Colombia before the end of
1999, and sales and content production offices in Chile and Venezuela during
2000. By offering content and interactive resources designed to be responsive to
our users' preferences, we seek to make our network their "home on the Internet"
and, in so doing, to create communities of users, develop user loyalty and
increase traffic on our Websites. The launch of each country Website represents
a potential new community of users. By building substantial communities of
users, we are developing a platform for generating revenues from advertising,
branded retail dial-up Internet access, or "connectivity", service and, in the
future, e-commerce. We recently began to offer connectivity services in
Argentina and Brazil and expect to offer similar services in Colombia before the
end of 1999. We are also beginning to develop e-commerce services for Spanish-
and Portuguese-speaking audiences in Latin America and the United States.

    Our founders believed that a scarcity of Spanish- and Portuguese-language
content was the principal factor limiting the growth of Internet usage in Latin
America. As a result, from our inception in mid-1997, we initially concentrated
on the development of a pilot Website for Argentina with quality content and
interactive resources in Spanish and, at the same time, carried out extensive
market testing to understand users' preferences. We then began to roll-out our
network of country Websites during 1998 and, most recently, launched our Website
in the United States in September 1999. Our registered users (meaning users who
have provided personal information such as name, e-mail address and address)
grew from 54,132 persons in June 1998 to 291,567 persons in July 1999. From
June 1998 to July 1999, the number of pages viewed by our users increased from
3.0 million to 21.0 million per month. On August 1, 1999, we launched our first
mass media-based branding and advertising campaign in Argentina, Brazil, Mexico
and Uruguay and, on September 9, 1999, launched the campaign in the United
States. In the first three months of this campaign (through October 31, 1999),
our registered users increased by approximately 69% to 498,515 at October 31,
1999 and the number of pages viewed per month by our users increased by over
250% to 73.9 million in that month. In March 1999, we also commenced measuring
unique visitors (meaning users who visit our Websites multiple times but who are
counted in the relevant period as having visited the Websites only one time).
The number of unique visitors has increased from 174,800 in March 1999 to
approximately 1.6 million in October 1999. We

                                       5
<PAGE>
attribute this recent growth principally to our mass media-based branding and
advertising campaign, and cannot predict whether such growth will continue.

    Our network is located at WWW.ELSITIO.COM for all of our Spanish-language
Websites and at WWW.OSITE.COM.BR for our Portuguese-language Website. An on-line
user accessing our network in any of the countries for which we operate a
country Website is directly linked to our Website for that user's home country;
other users are linked to our global Website. Our users encounter appealing
content and interactive resources in their native language and organized
according to eleven themes, which we call channels. These channels include,
among others, movies, music, news, parenting, relationships, shows, sports and
technology. Our users also receive access to free e-mail, chat rooms, bulletin
boards, personal home pages, contests and prizes. We regularly enhance our
Websites' features in response to user suggestions and our own service, content
and product developments. We provide content and community features on our
Websites to our users (including our registered users) free of charge.

    Each of our country Websites is supported by a team of management,
marketing, sales and content production personnel based in the relevant country.
Each team is responsible for providing country-specific content and community
features adapted to the cultural and other tastes of the relevant market. Our
in-country teams are supported by our global team, which provides technical and
design support and global content for our network. This structure affords our
users the dual advantages of, first, the size and resources of our network and,
second, the country-specific content and community features most useful to them.
Operationally, it permits us to maximize economies of scale to efficiently
support multiple markets with differing content and features from a single
global platform.

    In order to offer our users a broader range of Internet services and to
further foster user loyalty, we recently acquired IMPSAT Corporation's retail
dial-up access customers in Argentina and Brazil and are in the process of
acquiring its retail dial-up access customers in Colombia. The aggregate
purchase price for these acquisitions is $21.5 million. As a result of these
acquisitions, we expect to receive approximately 73,000 dial-up customers in the
three countries. These acquisitions should enable us to utilize our Websites in
Argentina, Brazil and Colombia as portals for our dial-up access customers, as
our connectivity customers will be directly linked to our Websites upon
connecting to the Internet, and to cross-market connectivity services to the
users of our network of Websites. To subscribe to our connectivity services, a
user pays a monthly fee to us in exchange for connectivity to the Internet. A
dial-up access subscriber automatically becomes a registered user of El Sitio's
network, although not vice versa. We will not acquire the telecommunications
infrastructure required to provide these services, but will instead outsource
that infrastructure from third-party providers--initially, under three-year
agreements with subsidiaries of IMPSAT Corporation. In conjunction with these
acquisitions, IMPSAT Corporation, which is a provider of private networks of
integrated data and voice communications systems in a number of countries of
Latin America, has become one of our major shareholders. We do not now offer or
intend to offer connectivity services in countries other than Argentina, Brazil
and Colombia.

    Our results of operations for the nine months ended September 30, 1999
reflect that we continue to be in an early stage of operations. We continue to
build sales and marketing teams, establish advertising and sales offices, and
implement our media-based branding and advertising campaigns. We incurred
increased expenses that more than offset revenue growth during the nine months
ended September 30, 1999. We recorded net revenues of $1.5 million and a net
loss of $13.9 million in the nine months ended September 30, 1999, compared to
net revenues of $609,000 and a net loss of $1.8 million in the corresponding
period of 1998. Our increased net losses for the nine-month period ended
September 30, 1999 were primarily attributable to an increase in personnel and
other expenses necessary to support the roll-out or expansion of offices and
Websites in Brazil, Mexico and the United States and in anticipation of the
launch of commercial operations in these and other countries during the period.
For the nine months ended September 30, 1999, El Sitio generated 46.9%, 29.9%
and 22.2% of its revenues from Argentina, Uruguay and Mexico, respectively.
After taking into account our

                                       6
<PAGE>
acquisitions of the three dial-up access businesses, approximately 50% of our
revenues in this nine-month period would have been generated from Brazil, 31%
from Argentina, 12% from Colombia, 4% from Uruguay and 3% from Mexico.

    We were incorporated in July 1997 in the British Virgin Islands. We are a
holding company with operating subsidiaries in Argentina, Brazil, Mexico, the
United States and Uruguay. Our principal executive offices are located at
Avenida Belgrano 845, 1092 Buenos Aires, Argentina, and our telephone number is
011-5411-4343-6700.

OUR MARKET OPPORTUNITY

    The Spanish- and Portuguese-speaking audiences in Latin America and the
United States together represent one of the fastest growing user groups on the
Web today. While we do not expect to have country Websites or operations for
every country in Latin America, our network is targeted to the entire Latin
American region. In the United States, we are currently targeting the
Spanish-speaking populations in Chicago, Houston, Los Angeles, Miami, New York,
San Antonio and San Diego. We are primarily targeting individual users, although
we anticipate that business and other entities will become important
participants in our communities of users.

    We believe a large and growing market consisting of Spanish- and
Portuguese-speaking audiences exists in Latin America and the United States for
content, connectivity and e-commerce services, and that this market presents us
with a significant opportunity. Latin America had a total population at the end
of 1998 of 492.4 million people, of whom more than two-thirds are under
35 years of age. The region had an aggregate gross domestic product in 1998 of
$2.0 trillion, of which Brazil, Mexico and Argentina accounted for more than
three-fourths. The wealthiest 20% of the Latin American population accounts for
approximately two-thirds of the overall buying power in the region and
constitutes our primary target market in Latin America. Internet use in Latin
America is expected to increase from an estimated 4.8 million users in 1998 to
19.1 million users in 2003. Internet advertising targeting Latin America is
projected to grow from approximately $23.6 million in 1998 to approximately
$948.9 million in 2003. Similarly, on-line sales in Latin America are projected
to increase from approximately $166.8 million in 1998 to approximately
$8.0 billion in 2003. As of May 1999, Internet penetration rates were 1.5% in
Argentina, 2.0% in Brazil, 6.0% in Colombia, 1.0% in Mexico and 2.9% in Chile.

    The United States has a total Hispanic population of approximately
31.4 million people, which has grown at a compound annual rate of 3.7% between
1996 and 1999. By 2000, the U.S. Hispanic population is expected to constitute
approximately 11% of the total U.S. population. Advertising targeting U.S.
Hispanics was $1.7 billion in 1998. As of January 1, 1998, U.S. Hispanics
represented $273.2 billion in annual buying power. As of May 1999, the Internet
penetration rate for the U.S. Hispanics was approximately 19.0%.

OUR STRATEGY

    Our goal is to become the leading Internet network for Spanish- and
Portuguese-speaking audiences in Latin America and the United States. To achieve
our goal, and to take advantage of our market opportunity, we continue to
implement a strategy consisting of the following principal elements:

    - BUILDING A MARKET-LEADING NETWORK. We seek to build a leading Internet
      network by:

        V further developing country-specific and regional content;

        V incorporating additional community-building features; and

        V strengthening our brand identity.

                                       7
<PAGE>
    - GENERATING REVENUES FROM OUR NETWORK. We seek to increase substantially
      revenues from our network by:

        V forging one-on-one relationships with advertisers;

        V integrating connectivity services into our network; and

        V developing our e-commerce business.

    - LEVERAGING STRATEGIC RELATIONSHIPS. We intend to leverage our existing
      relationships with shareholders and enter into new strategic relationships
      to expand our network and enhance our content, marketing and sales.

OUR SHAREHOLDERS

    Roberto Vivo-Chaneton, our chairman, and Roberto Cibrian-Campoy, our chief
executive officer, founded our company in 1997. Mr. Vivo is a co-founder and
deputy chief executive officer of IMPSAT Corporation. Mr. Cibrian was the
founder and the president of Cibrian-Campoy Creativos, S.A., an Argentine
company which engaged in electronic arts, computer animation and multimedia and
which was the predecessor entity for our Argentine subsidiary.

    In July 1999, we completed a private placement of 6,334,004 Class A
convertible preferred shares for a gross purchase price of $44.4 million,
consisting of 5,477,088 shares sold for $38.4 million in cash and 856,916 shares
to be issued on a quarterly basis through January 2001 in exchange for
$6.0 million in non-cash advertising time credits. Each Class A convertible
preferred share will, after giving effect to a 2-for-1 share split, convert
automatically into two common shares upon completion of this offering.

    Our principal shareholders, in addition to Mr. Vivo and Mr. Cibrian,
include:

    - IAMP (El Sitio) Investments Ltd., an investment fund jointly controlled by
      Hicks, Muse, Tate & Furst Incorporated and the Cisneros Group of
      Companies;

    - SLI.Com, an investment fund controlled by Guillermo Liberman, an Argentine
      entrepreneur with interests in agribusiness, fisheries, telecommunications
      and hotel development;

    - GCC Investments, LLC, an indirect subsidiary of GC Companies Inc., which
      owns and operates General Cinema Theatres; and

    - IMPSAT Corporation, a Latin American telecommunications company.

    In mid-November 1999, we completed a private placement of 1,111,111 Class B
convertible preferred shares for a purchase price of $10.0 million in cash, or
$9.00 per Class B convertible preferred share. Purchasers of the Class B
convertible preferred shares consisted of Intel Atlantic, Inc., a subsidiary of
Intel Corporation, and Latinvest Asset Management do Brasil, Ltda., an affiliate
of Globalvest Management Company, L.P. The Class B convertible preferred shares
have an annual dividend rate of 8%. Each Class B convertible preferred share
will automatically convert, on the date six months after the closing of this
offering, into one common share. The difference between the initial public
offering price per common share and $9.00 price per Class B convertible
preferred share will be amortized as a deemed dividend during the same six-month
period.

                             SUMMARY FINANCIAL DATA

    The following financial data should be read in conjunction with the
consolidated financial statements and the unaudited pro forma financial
information, "Selected Financial Data" and "Management's Discussion and Analysis
of Financial Condition and Results of Operations" in this prospectus.

    The pro forma financial information reflects:

    - our acquisitions of the retail dial-up access customers in Argentina and
      Brazil from IMPSAT Corporation, and our pending acquisition of its retail
      dial-up access customers in Colombia, for approximately $21.5 million in
      the aggregate and the related purchase by IMPSAT Corporation of 3,070,615
      of our Class A convertible preferred shares for $21.5 million; and

    - the private placement in mid-November 1999 of 1,111,111 Class B
      convertible preferred shares for an aggregate purchase price of
      $10.0 million in cash.

    The selected pro forma as adjusted balance sheet data give effect to the
sale of the common shares in, and the receipt of the net proceeds from, this
offering. We have assumed an initial public offering price of $12.00 per share,
which is the mid-point of the estimated range of offering prices presented on
the cover page of this prospectus. The pro forma as adjusted data also assume
that all of our outstanding Class A convertible preferred shares have been
converted into our common shares, which will automatically occur upon the
closing of this offering.

    We prepare our consolidated financial statements and the pro forma financial
information in U.S. dollars in accordance with generally accepted accounting
principles in the United States, which is commonly called "U.S. GAAP."

    Results of operations for the periods presented are not necessarily
indicative of results of our operations for future periods.

                                  RISK FACTORS

    AN INVESTMENT IN OUR COMMON SHARES INVOLVES A HIGH DEGREE OF RISK. YOU
SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS AND THE OTHER INFORMATION
IN THIS PROSPECTUS BEFORE PURCHASING OUR SHARES.

    FOR PURPOSES OF THIS "RISK FACTORS" SECTION OF THIS PROSPECTUS, WHEN WE
STATE THAT A RISK, UNCERTAINTY OR PROBLEM MAY, COULD OR WOULD HAVE AN "ADVERSE
EFFECT ON OUR COMPANY," WE MEAN THAT THE RISK, UNCERTAINTY OR PROBLEM MAY, COULD
OR WOULD HAVE AN "ADVERSE EFFECT ON THE BUSINESS, RESULTS OF OPERATIONS,
FINANCIAL CONDITION, CASH FLOW OR PROSPECTS OF OUR COMPANY," IN EACH CASE EXCEPT
AS OTHERWISE INDICATED OR AS THE CONTEXT MAY OTHERWISE REQUIRE. YOU SHOULD VIEW
SIMILAR EXPRESSIONS IN THIS SECTION AS HAVING A SIMILAR MEANING.

RISKS RELATED TO OUR COMPANY

WE HAVE ONLY BEEN IN BUSINESS FOR A SHORT PERIOD OF TIME, SO YOUR BASIS FOR
EVALUATING OUR COMPANY IS LIMITED.

    We commenced operations in July 1997 and began the roll-out of our network
during 1998. We commenced our first mass media-based branding and advertising
campaign in August 1999 in an effort to generate a high volume of user traffic
on our Websites. Accordingly, we have a limited operating and financial history
upon which you can base your evaluation of an investment in our common shares.

    We are subject to the risks, uncertainties and problems frequently
encountered by companies in early stages of operations, particularly companies
in new and rapidly developing markets, such as the Internet industry.

    These risks, uncertainties and problems include, among others, the
following:

    - any inability to maintain and increase levels of traffic on our Websites;

    - any failure to continue to develop and extend the EL SITIO (in Brazil, O
      SITE) brand;

    - any inability to meet minimum guaranteed impressions under our advertising
      agreements;

    - any failure to anticipate and adapt to developing markets;

    - any inability to upgrade and develop our systems and infrastructure and
      attract new personnel in a timely and effective manner;

    - any failure of our network to handle efficiently our Web traffic;

    - any inability to generate significant revenues from e-commerce;

    - any failure to manage rapidly expanding operations; and

    - the level of use of the Internet and online services and consumer
      acceptance of the Internet and other online services.

    We cannot assure you that we will be successful or that we will be able
effectively to compete and achieve market acceptance or otherwise address the
risk factors disclosed in this prospectus.

                                       12
<PAGE>
WE HAVE A HISTORY OF LOSSES AND EXPECT TO CONTINUE TO INCUR INCREASING LOSSES IN
THE NEXT SEVERAL YEARS.

    We have not achieved profitability to date, and we anticipate that we will
incur substantial and increasing losses through 2002. We expect to incur a net
loss of approximately $30 million in 1999. Our business plan contemplates that
we will first become profitable in 2003. We believe that our revenues, chiefly
from advertising and connectivity services, will exceed our expenses in 2003 as
a result of our branding and advertising campaigns and related marketing efforts
prior to that year and the further development of our communities of users.
Until that year, we will continue to incur losses and negative cash flow as we
fund operating and capital expenditures in areas such as content and service
development, marketing and brand promotion, additional personnel and network
infrastructure. The extent of these losses will depend, in part, on the amount
of growth in our revenues. We cannot assure you that our losses will not further
increase in the future or that we will ever achieve or sustain profitability.

WE MAY FAIL TO IMPLEMENT SUCCESSFULLY OUR BUSINESS STRATEGY.

    Our business strategy relies upon the creation of high quality content for
our Website for each country in which we operate and for each of our targeted
metropolitan areas in the United States. Our strategy assumes that consumers
will be attracted to the country-specific content and community features on our
Websites, which will, in turn, allow us to sell advertising, sponsorships and
connectivity services and, in the future, to develop relationships with
merchants for e-commerce designed to reach those consumers. Our strategy remains
unproven and, among other things, could entail higher operating expenses than
are or may be incurred by competitors which are pursuing a more pan-Latin
American approach with limited country-specific content.

    Our strategy may not be successful, and if not successful, we may not be
able to modify it in a timely and successful manner in the rapidly evolving
Internet industry. In addition, we could fail to develop strategies to
capitalize on opportunities in new and unproven areas.

WE WILL NOT BECOME PROFITABLE IF WE DO NOT ATTRACT A SUBSTANTIAL NUMBER OF USERS
AND ADVERTISERS.

    We must continually enhance and improve our Website content and services to
attract, and to meet the expectations of, our users and advertisers. We also
must continue to:

    - improve the features and functionality of our Websites and our dial-up
      access businesses; and

    - develop other services and products to attract users, advertisers and
      e-commerce partners.

In the countries for which we establish new Websites, we believe we will
encounter the same challenges in attracting users and advertisers as in the
countries where we currently conduct operations.

    We constantly seek to deliver the content, features and functionality
desired by our target audience. If other Websites or networks, or Internet
service providers, present more desirable content, features or functionality,
our user traffic could be adversely affected. We cannot assure you that we can
successfully identify new service opportunities and develop and bring new
services and products to market in a cost-efficient and timely manner. Any
failure to develop and introduce new services and service enhancements that are
compatible with industry standards and satisfy customer requirements would have
a material adverse effect on our company.

                                       13
<PAGE>
WE MUST DEVELOP OUR BRAND AND GENERATE INCREASED ADVERTISING REVENUES IN ORDER
TO CREATE A VIABLE BUSINESS.

    We must continue to establish and develop our EL SITIO (in Brazil, O SITE)
brand. Brand loyalty is critical to our ability to expand our user base and our
advertising, connectivity services and e-commerce revenues. We believe that the
importance of brand recognition will increase as the number of Spanish-and
Portuguese-language Websites targeting Latin America and the U.S.
Spanish-speaking market increases. We intend to devote considerable resources
for marketing campaigns, both on-line and in traditional media, to promote our
brand. However, unlike our on-line advertising, which gives us immediate
feedback and allows us to adjust promptly our marketing messages, the
effectiveness of advertising in traditional print and broadcast media is more
difficult to assess. If our marketing efforts are unsuccessful, we may fail to
establish EL SITIO and O SITE as leading brands in our markets. We cannot assure
you that our brand building initiatives and expenditures for this purpose will
prove effective.

    Our success in promoting and enhancing our brand will also depend on our
ability to provide high quality content, features and functionality. If we fail
to promote successfully our brand, if users of our Websites, or our connectivity
services or if advertisers or e-commerce partners do not perceive our services
to be of high quality, the value of our brand could be diminished, which would
have a material adverse effect on our company.

OUR GROWTH AND EXPANSION MAY STRAIN OUR ABILITY TO MANAGE OUR OPERATIONS AND OUR
FINANCIAL RESOURCES.

    We are undergoing rapid growth and plan to continue to grow rapidly, both in
existing markets and by means of expansion into new geographic markets. Rapid
growth places significant strains on our network infrastructure, our managerial,
technical and editorial personnel, and our financial and other resources. To
support growth, we must implement new or upgraded operating and financial
systems, procedures and controls for our existing operations in Argentina,
Brazil, Mexico, the United States and Uruguay, as well as in additional
countries in which we may seek to develop our business. Any failure to expand
and integrate these areas in an efficient manner could have a material adverse
effect on our company.

    We have acquired the retail dial-up access customers of IMPSAT Corporation
in Argentina and Brazil and are in the process of acquiring its retail dial-up
access customers in Colombia. We expect to complete the Colombia acquisition by
the end of 1999. Prior to these acquisitions, our company had no experience in
operating a connectivity services business. In addition, any failure to
integrate these acquisitions, or any other acquired business, could have an
adverse effect on our company.

    The aggregate $21.5 million purchase price for the acquisitions of these
retail dial-up access customers has been allocated principally to an intangible
asset consisting of the newly acquired customer base. This intangible asset will
be amortized over the next five years and, as such, will be reflected as an
expense in our statement of operations in future periods. To the extent that we
fail to retain this customer base during this period, this intangible asset
could be deemed to be impaired, in which case an amount in excess of the
anticipated amortization expense would be charged to our results of operations
and could result in substantially increased losses or, in later years, reduced
profits. As a result, our future financial performance could be materially and
adversely affected if we are not successful in preserving and developing our
newly acquired connectivity customer base.

                                       14
<PAGE>
    Our ability to achieve and to manage planned growth will depend upon, among
other factors, our success in:

    - hiring and retaining qualified management, technical and marketing
      personnel;

    - maintaining the high levels of customer service required to retain users
      while undertaking expansion; and

    - expanding our network infrastructure to service a growing user base.

If we fail to achieve and manage growth, our company, as well as the market
price of our common shares, could be adversely affected.

WE MUST INCREASE OUR ADVERTISING AND OTHER REVENUES IN CASH IN ORDER TO EXPAND
OUR BUSINESS.

    As a network of Websites, our business model is predicated upon our ability
to increase significantly our advertising revenues. Although we will derive
subscriber-based revenues from our acquisitions of the retail dial-up access
customers of IMPSAT Corporation in Argentina and Brazil and our pending
acquisition of its retail dial-up access customers in Colombia, our branded
connectivity services are complementary to the development of communities of
users. Our business model emphasizes growth in advertising revenues through
country-specific and regional advertising agreements. Our growth of advertising
revenues will depend, among other factors, on:

    - the level of acceptance that Internet advertising achieves in Latin
      America, and the growth of the aggregate amount spent on Internet
      advertising in our markets;

    - the market recognition and prestige of our brand and trademarks;

    - the attractiveness of our advertising pricing schedules;

    - the effectiveness of our advertising sales personnel in each of our
      markets; and

    - our ability to generate and continue to grow a large community of loyal
      users in our markets.

    Our five largest advertisers accounted for approximately 40.7% of our total
revenues in the nine months ended September 30, 1999 and approximately 77% of
our total revenues for the nine months ended 1998. Our largest advertiser alone
accounted for approximately 12.8% and 20.4% of our total revenues in the first
nine months of 1999 and 1998, respectively. The loss of any of our major
existing advertisers, unless replaced by other advertisers, could have a
material adverse effect on our company.

    We have received a significant portion of our historical net revenues from
reciprocal services arrangements, pursuant to which we exchange advertising
space on our network for advertising space on television and radio or for
telecommunications services, in lieu of cash payments. In the nine months ended
September 30, 1999, we derived advertising revenues valued at approximately
$554,000, or 36% of our total net revenues for this period, from these non-cash
reciprocal services arrangements. For the year ended December 31, 1998, we
derived approximately $180,000, or 23% of our total net revenues, from these
arrangements. We expect that non-cash revenues from reciprocal services
arrangements will continue to account for a significant portion of our revenues
in the foreseeable future.

                                       15

WE MUST MAINTAIN ACCESS TO QUALITY CONTENT PROVIDED BY THIRD PARTIES IN ORDER TO
DEVELOP OUR SUBSCRIBER BASE.

    Although we seek to produce or edit a substantial portion of the content for
our Websites, we continue to rely upon third parties, such as Reuters, Agence
France-Presse and CBS Sportsline, to provide global content to complement our
own content and thus make our Websites more attractive to users and, by
extension, advertisers. Most of our arrangements with third-party providers of
content are not exclusive, are short-term and may be terminated at the
discretion of the other party. Any termination of any of our arrangements with
some of these providers of content could have an adverse effect on our company.

OUR BUSINESS DEPENDS UPON STABLE RELATIONSHIPS WITH KEY SUPPLIERS.

    We have no long-term contracts with our suppliers. We are dependent on
third-party suppliers for our leased-line connections and bandwidth. Some of
these suppliers are or may become competitors of our company, and they are not
subject to any contractual restrictions upon their ability to compete with us.
If these suppliers change their pricing structures, we may be adversely
affected. Moreover, any failure or delay on the part of our network providers to
deliver bandwidth to us or to provide operations, maintenance and other services
with respect to such bandwidth in a timely or adequate fashion could adversely
affect our company.

    In connection with our acquisitions of retail dial-up access customers from
IMPSAT Corporation, we are not acquiring the telecommunications infrastructure
to provide these services and will instead outsource that infrastructure from
third-party providers--initially, under three-year services agreements with
subsidiaries of IMPSAT Corporation. Our agreements with these subsidiaries of
IMPSAT Corporation, pursuant to which they will provide telecommunications
infrastructure for our dial-up access customers, do not restrict IMPSAT
Corporation from competing directly with us or providing better rates to other
dial-up access providers. These agreements, however, permit us to terminate the
agreements without any penalties after one year if we receive an offer from a
lower-price service provider and IMPSAT Corporation does not match that service
provider's price. If IMPSAT Corporation competes directly with us, charges us
above-market rates for telecommunications infrastructure or offers cut-rate
telecommunications infrastructure to our competitors in the retail dial-up
access business, our business could be adversely affected.

WE MUST FURTHER DEVELOP STRATEGIC RELATIONSHIPS TO STRENGTHEN OUR COMPETITIVE
POSITION.

    In our initial stage of operations, we focused upon understanding our target
markets and delivering high quality services and products designed for such
markets. More recently, we have sought to establish strategic relationships with
leading content providers, dial-up access providers, e-commerce partners, and
technology and infrastructure providers. To date, our principal strategic
relationships have been with our shareholders and their affiliates, such as
Hicks, Muse, Tate & Furst Incorporated, the Cisneros Group of Companies, and
IMPSAT Corporation. We may depend, in part, upon strategic relationships to help
to develop our business. Our future growth will depend upon maintaining our
existing strategic relationships as well as our ability to establish new
relationships.

WE COULD EXPERIENCE CAPACITY CONSTRAINTS AND UNEXPECTED SYSTEM INTERRUPTIONS,
WHICH COULD IMPEDE THE DEVELOPMENT OF OUR BUSINESS.

    The number of pages of information transmitted over our network, commonly
referred to as "page views," has continued to increase over time. We are
actively trying to increase our level of page views.

                                       16
<PAGE>
As a result, our network must accommodate a high volume of traffic, often at
unexpected times. We have, to date, experienced limited capacity constraints in
terms of our ability to serve our increasing user volumes. We are in the process
of improving our network infrastructure to ensure that we will be able to handle
future increases in traffic. We are migrating our platform and our applications
to a Unix platform using Sun Microsystems servers. We do not anticipate that
this migration process, which is expected to be completed before the end of
1999, will affect the continuous operations of our network. However, any break
in the continuous operations of our network could have a material adverse effect
on our company.

    We make our Websites available using 17 Microsoft Windows NT servers and 3
Linux servers as our central production servers, which servers are currently
located at the server farm facilities of Exodus Communications in New Jersey. We
also have a redundant server located at the Miami, Florida server farm
facilities of IMPSAT Corporation. Any failure by Exodus Communications or IMPSAT
Corporation to protect our systems against damage from fire, weather, power
loss, telecommunications failure, break-ins or other events could have a
material adverse effect on our company.

    We may also, from time to time, experience interruptions due to hardware
failures, unsolicited bulk e-mail and operating system failures. Because our
revenues depend on the number of users of our network, we will be adversely
affected if we experience frequent or long system delays or interruptions. If
delays or interruptions continue to occur:

    - our users could perceive our network as being unreliable;

    - traffic on our Website could deteriorate; and

    - our brand could be adversely affected.

    Any failure on our part to minimize or prevent capacity constraints or
system interruptions could have an adverse effect on our company.

WE MAY HAVE DIFFICULTY IN OBTAINING THE ADDITIONAL FINANCING REQUIRED TO DEVELOP
OUR BUSINESS.

    As a company in an early stage of operations, and in order to develop and
expand our business, we anticipate that we will require substantial additional
equity and debt financing after this offering. Under our business plan, we
currently estimate that we will require additional financing between early 2001
and 2003 in the amount of approximately $50 million to provide sufficient
working capital until we become profitable, which is anticipated in the latter
year. Obtaining additional financing will be subject to a number of factors,
including, without limitation, the following:

    - the stage of operations of our company;

    - our actual or anticipated results of operations, financial condition and
      cash flow;

    - investor sentiment towards companies conducting business in Latin America;
      and

    - generally prevailing market conditions.

These factors may make the timing, amount, terms and conditions of additional
financing unattractive for us.

    If additional funds are raised through the issuance of equity securities,
the percentage ownership of our then current shareholders will be reduced, and
the new equity securities may have rights,

                                       17
<PAGE>
preferences or privileges senior to those of the holders of our common shares.
If additional funds are raised through the issuance of debt securities, these
securities would have some rights, preferences and privileges senior to those of
the holders of our common shares, and the terms of this debt could impose
restrictions on our operations and result in significant interest expense to us.

    In the event that we are unable to raise sufficient financing on
satisfactory terms and conditions in the future, our company would be adversely
affected.

WE MUST RETAIN KEY MANAGERS AND REQUIRE ADDITIONAL QUALIFIED PERSONNEL TO
DEVELOP OUR BUSINESS IN AN INDUSTRY IN WHICH IT IS DIFFICULT TO ATTRACT AND
RETAIN QUALIFIED PERSONNEL.

    Our future performance depends, in large part, on the continued service of
our senior management. We rely, in particular, on the strategic guidance of
Roberto Vivo-Chaneton, co-founder and chairman of our company, and on the
services of Roberto Cibrian-Campoy, co-founder and chief executive officer of
our company. The loss, for any reason, of the services of either of these
individuals could have a material adverse effect on our company.

    Our strategy of emphasizing country-specific content and advertising also
requires the hiring and retention of highly qualified personnel in each market.
After they are employed, the knowledge, expertise and relationships of our
personnel makes their retention important to our success. We expect to continue
to enter into share option and non-competition agreements with key personnel.
However, we cannot assure you that we will be able to retain our key personnel
or that we will be able to attract and retain such additional highly qualified
technical and managerial personnel in the future. Any inability to attract and
retain the personnel necessary to support the growth of our business could have
an adverse effect on our company.

WE WILL BE CONTROLLED AFTER THIS OFFERING BY A SMALL GROUP OF EXISTING
SHAREHOLDERS, WHOSE INTERESTS MAY DIFFER FROM THOSE OF OTHER SHAREHOLDERS.

    Prior to this offering, our directors and officers and their respective
affiliates beneficially owned, in the aggregate, a significant majority of our
issued and outstanding share capital. We expect that these shareholders will
continue to own a significant portion of our share capital after this offering.
As a result, these shareholders will be able to control the outcome of all
matters requiring shareholder approval, including the election of directors and
approval of mergers, acquisitions and other significant corporate transactions.
You should understand that there may be circumstances in which interests of
these shareholders may conflict with your interests.

    Commercial and other transactions between our company, on the one hand, and
our directors, officers and controlling shareholders and their affiliates, on
the other, create the potential for, or could result in, conflicting interests.
For example, Roberto Vivo-Chaneton, Ricardo Verdaguer and Sofia Pescarmona,
three of our directors, also serve as directors and senior officers of IMPSAT
Corporation. These relationships may give rise to conflicts of interest from
time to time relating to contracts, such as the telecommunications services
agreements that we are entering into with IMPSAT Corporation, corporate
opportunities and use of directors' time and expertise. We also have acquired
IMPSAT Corporation's retail dial-up access customers in Argentina and Brazil and
are in the process of acquiring its retail dial-up access customers in Colombia,
which are transactions involving our company and this related party. Our board
of directors is in the process of developing procedures with a view to
minimizing such potential conflicts of interest and has adopted guidelines
regarding related party transactions. We intend to enter into all related party
transactions on an arm's length basis (measured against terms that would be
offered by an unaffiliated third party). We cannot assure you, however, that all
of these future transactions will be free of conflicting interests.

                                       18
<PAGE>
WE MUST PRESERVE OUR INTELLECTUAL PROPERTY RIGHTS, WHICH ARE ESSENTIAL TO THE
DEVELOPMENT OF OUR BUSINESS.

    We consider our EL SITIO, O SITE and medallion design trademarks and service
marks to be important to our success. We are pursuing the registration of our
trademarks and service marks in the United States and in key countries of Latin
America as well as in Spain and Portugal. Although some of these countries have
registered our marks, we cannot predict with certainty whether the trademark
offices of the remaining countries will do the same. If we are unable to obtain
a registration in a particular country, we would have trademark or service mark
rights to the extent that we use the mark, but the rights would not be as strong
as if they were registered. Some companies, including other participants in the
Internet industry, use and/or may use trademarks or service marks in English or
other languages which, when translated, are similar or identical to certain of
our core marks. Usage of these marks by other parties could hinder our ability
to build a unique brand identity and may possibly lead to trademark disputes, in
that we may be sued for trademark infringement in court or we may have the
validity of our applications and/or registrations challenged at government
agencies. Although we do not believe that any proceedings against us ultimately
would be meritorious, we cannot provide any assurances to you in this regard. A
judgment against us in an intellectual property-based proceeding could result in
the loss of our ability to use one or more of our marks, as well as the
imposition of monetary damages. Should we lose the right to use a trademark or
service mark, we may be forced to adopt a new mark, which would result in the
loss of substantial resources and brand identity. In any event, whether
successful or not, litigating a trademark dispute would result in the
expenditure of monetary resources and the diversion of executives' time. Any
inability to protect, enforce or use our trademarks, service marks or other
intellectual property may have a material adverse effect on our company.

    We also depend upon technology licensed from third parties for chat,
homepage, search and related Web services. Any dispute with a licensor of the
technology may result in our inability to continue to use that particular
technology. Additionally, there may be patents issued or pending that are held
by third parties and that cover significant parts of the technology, products,
business methods or services used to conduct our business. We cannot be certain
that our technology, products, business methods or services do not or will not
infringe valid patents or other intellectual property rights held by third
parties. In the event that a third party alleges infringement, we may be forced
to take a license, which we may not be able to obtain on commercially reasonable
terms. We may also incur substantial expenses in defending our company against
third-party infringement claims regardless of the merit of these claims.
Successful infringement claims against us could result in substantial monetary
liability and/or being prevented by a court from conducting all or a part of our
business that falls within the scope of the asserted patent, leading to
substantial expenditures to redesign and/or license technology.

OUR RESULTS OF OPERATIONS MAY FLUCTUATE DUE TO SEASONALITY.

    The level of use of our network may be seasonal in nature. Historically,
telecommunications use in Latin America has been significantly lower during the
first calendar quarter of the year because:

    - it includes the summer months in much of Latin America;

    - affluent segments of the population tend to take extended vacations during
      these months; and

    - schools and universities are generally closed.

Our advertising revenues may also be subject to seasonal fluctuations.
Advertisers in traditional media have spent less in the first and second
calendar quarters. We believe that these seasonal trends may affect our results
of operations.

                                       19
<PAGE>
THE MULTI-COUNTRY NATURE OF OUR BUSINESS EXPOSES US TO ADDITIONAL
INTERNATIONAL-BASED RISKS.

    We are subject to a broad range of risks inherent in businesses with
operations in multiple countries, including, among others, the following:

    - unexpected changes in governmental laws and regulations;

    - difficulties and costs of staffing and managing international operations;

    - potentially adverse tax consequences;

    - uncertain protection for intellectual property rights;

    - trade barriers for goods which may be sold over our network;

    - difficulties in maintaining and upgrading our systems;

    - export restrictions and controls;

    - currency fluctuation and exchange risks; and

    - economic, political and other conditions in the countries in which we
      currently, or may seek to, conduct business.

    Any of these factors, many of which are outside our control, could have a
material adverse effect on our company.

RISKS RELATED TO OUR INDUSTRY

WE OPERATE IN AN EXTREMELY COMPETITIVE MARKET AND FACE COMPETITION FROM MORE
DEVELOPED COMPANIES WITH GREATER RESOURCES.

    Many companies already provide Website and on-line destinations targeted to
Spanish- and Portuguese-speaking audiences in Latin America, the United States
and elsewhere. Competition for users, advertisers and e-commerce partners is
intense and is expected to increase significantly in the future, particularly
because there are no substantial barriers to entry in our industry.

    We face competition on both country and regional levels. Our primary
competitors include, among others, StarMedia and Terra Networks (in most of
Latin America and the United States), Quepasa.com and Yupi (in the United
States), Clarin Digital (in Argentina) and Universo Online (in Brazil). We also
face competition from Spanish- and/or Portuguese-language versions of services,
such as Yahoo!, America Online and Prodigy Communications. Our competitors may
develop content that is better than ours or that achieves greater market
acceptance. It is also possible that new competitors may emerge and acquire
significant market share. Some of our established competitors and potential new
competitors may have better brand recognition and significantly greater
financial, technical, and marketing resources than our company. Any significant
loss of users to our competitors could have a material adverse effect on our
company.

    As a result of our completed or pending acquisitions of the retail dial-up
access customers in Argentina, Brazil and Colombia of IMPSAT Corporation, we
will be entering the connectivity services market, which is extremely
competitive and is characterized by rapidly changing technology and evolving
standards. As a result of these acquisitions, we will be amortizing an
intangible asset relating to our customer base in subsequent periods. To the
extent that we fail to retain this customer base, this intangible asset could be
deemed to be impaired, in which case we could sustain substantially increased
losses or, in later years, reduced profits. We also do not own
telecommunications assets and will, therefore, depend upon telecommunications
providers to carry our Internet traffic. Increased competition could require us
to lower our prices, increase our selling and marketing expenses, and raise
subscriber acquisition costs. New technologies permitting faster connectivity
may make our newly acquired retail dial-up access businesses obsolete. We may
not be able to retain our subscribers or, if we do, we may not be able to offset
the effect of increased costs through an increase in subscribers, subscriber
revenues or revenues from other sources.

                                       20
<PAGE>
    If low-cost or free connectivity is offered in Latin America, our
subscribers will have cost-effective alternatives to our service, and they may
have more than one Internet account or may switch to another dial-up access
provider in their country if they are unable to gain access to our service. As a
result, usage of our services by subscribers may decrease; our customer
turnover, which is known as "churn," could increase; and we may be compelled to
reduce our prices further.

    Recently, various cable and telephone companies have made announcements
regarding the planned deployment of broadband services for high-speed Internet
access. These services would include new technologies, such as cable modems,
wireless communications and digital subscriber line, commonly known as DSL. In
addition, a number of free Internet access services have recently been
introduced, particularly in non-U.S. markets, and some Internet access providers
are now offering subsidized or free personal computers to their subscribers.
These trends, if they materialize in Latin America or the U.S., could have a
material adverse effect on our company.

WE WILL BE ADVERSELY AFFECTED IF THE INTERNET DOES NOT BECOME WIDELY ACCEPTED AS
A MEDIUM FOR ADVERTISING AND E-COMMERCE.

    Advertising revenues will continue to be an important component of our total
revenues. In order for us to generate these revenues, advertisers and
advertising agencies must direct a portion of their advertising budgets to the
Internet and, specifically, to our network. Many of our current or potential
advertising and e-commerce partners have limited experience using the Internet
to advertise or to sell their products and services and have not devoted a
significant portion of their budgets to Internet-based advertising and commerce.
The adoption of Internet advertising, particularly in Latin America, requires
the acceptance of a new method of conducting business and exchanging
information. Advertisers that have invested substantial resources in other media
forms may be reluctant to adopt a new method that may limit or compete with
their existing efforts. These businesses may find Internet advertising to be
less effective for promoting and selling their products and services than is
traditional print and broadcast media. We will be adversely affected if Internet
advertising and e-commerce fail to develop or develop slowly in Latin America.

CHANGES IN THE LEGAL AND REGULATORY ENVIRONMENT FOR OUR INDUSTRY COULD INCREASE
OUR COSTS AND LENGTHEN THE PERIOD FOR US TO BECOME PROFITABLE.

    Government regulation has not materially restricted use of the Internet in
our markets to date. However, the legal and regulatory environment pertaining to
the Internet remains relatively undeveloped and may change. New laws and
regulations could be adopted, and existing laws and regulations could be applied
to the Internet and, in particular, to e-commerce. New and existing laws and
regulations could cover issues, including, among others, the following:

    - sales and other taxes;

    - user privacy;

    - pricing controls;

    - characteristics and quality of products and services;

    - consumer protection;

    - cross-border commerce;

    - libel and defamation;

    - copyright, trademark and patent infringement; and

    - other claims based on the nature and content of Internet materials.

Changes in government regulation in any of the countries in which we operate
could increase our costs and prevent us from delivering our services and
products over the Internet. It could also slow the

                                       21
<PAGE>
growth of the Internet, which could, in turn, delay growth in demand for our
network and adversely affect our company.

WE MAY BECOME SUBJECT TO LEGAL LIABILITY BASED ON THE CONTENT PROVIDED THROUGH,
AND THE PRODUCTS SOLD OVER, OUR NETWORK.

    The laws in the United States and in Latin American countries relating to
the liability of on-line service providers, such as our company, for activities
of their users remains unsettled. Claims have been made against other on-line
service providers for defamation, negligence, copyright or trademark
infringement, obscenity or other grounds based on the nature and content of
information that was posted on-line by these providers or their visitors. We
could become subject to similar claims. It is also possible that, if information
provided through our services contains errors, third parties could make claims
against us for losses incurred in reliance on the information. Finally, we could
face personal injury or other product liability claims arising from the use of
products sold through our Website.

    We offer e-mail services, which expose us to potential liabilities or claims
resulting from:

    - unsolicited e-mail;

    - lost or misdirected messages;

    - illegal or fraudulent use of e-mail; or

    - interruptions or delays in e-mail service.

Investigating and defending these claims may involve substantial expenses, even
if they do not result in liability.

    Although we carry general liability insurance, our insurance may not cover
all potential claims to which we are exposed or may not be adequate to indemnify
us for all liabilities that may be imposed. Any imposition of liability that is
not covered by insurance or is in excess of insurance coverage could have a
material adverse effect on our company. In addition, the increased attention
focused on liability issues as a result of these lawsuits and legislative
proposals could impact the overall growth of Internet use.

WE WILL BE ADVERSELY AFFECTED IF WE FAIL TO RESPOND EFFECTIVELY AND ON A TIMELY
BASIS TO RAPID TECHNOLOGICAL CHANGE.

    The Internet industry is characterized by rapidly changing technology,
evolving industry standards, frequent new product and service announcements,
introductions and enhancements, and changing consumer demands. Our future
success will depend on our ongoing ability to improve the performance, features
and reliability of our Internet services and products in response to competitive
product, feature and service offerings and the evolving demands of the
marketplace. New services, products and technologies may be superior to the
services and technologies that we use, and may render our services and
technologies obsolete or require us to incur substantial expenditures to modify
or adapt our services, products or technologies.

OUR NETWORK OPERATIONS MAY BE VULNERABLE TO HACKING, VIRUSES AND OTHER
DISRUPTIONS.

    Internet usage could decline if any well-publicized compromise of security
occurs. "Hacking" involves efforts to gain unauthorized access to information or
systems or to cause intentional malfunctions or loss or corruption of data,
software, hardware or other computer equipment. Hackers, if successful, could
misappropriate proprietary information or cause disruptions in our services. In
August 1999, the Microsoft Windows NT operating system employed by our servers
was subject to a disruption, which may have been caused by either unusually
heavy traffic on our network or a hacking attack. This disruption, which
occurred intermittently over a two-day period, caused a significant

                                       22
<PAGE>
reduction in the speed at which our servers could transmit data, resulting in
delays for our users in accessing our Websites and features on our Websites. To
address this particular situation, we implemented a number of general security
measures, including migrating our operating system to a Unix platform that we
consider more stable and hiring an Internet security company. We cannot assure
you that these measures will be effective. Security breaches could have a
material adverse effect on our business. In addition, the inadvertent
transmission of computer viruses could expose us to a material risk of loss or
litigation and possible liability.

OUR COMPUTER SYSTEMS AND THOSE OF OUR BUSINESS PARTNERS MAY NOT BE YEAR 2000
COMPLIANT, WHICH MAY CAUSE SYSTEM FAILURES AND DISRUPTIONS OF OPERATIONS.

    Many currently installed computer systems and software products are coded to
accept or recognize only two digit entries in the date code field. These systems
and software products will need to accept four digit entries to distinguish 21st
century dates from 20th century dates. As a result, computer systems and/or
software used by many companies and governmental agencies need to be upgraded to
comply with such Year 2000 requirements or risk system failure or
miscalculations which may cause disruptions to normal business activities.

    We have conducted an inventory, and developed testing procedures, for all
software and other systems that we believe might be affected by Year 2000
issues. We have tested our computers, servers and other equipment. If we
discover any Year 2000 issues with our equipment or the equipment acquired from
IMPSAT, we expect to replace the necessary hardware and/or software with
versions that will resolve the difficulties. Because third parties developed and
currently support many of these systems that we use, a significant part of this
effort is directed to ensuring that these third-party systems are Year 2000
compliant. We are unable to test certain systems, such as our telephone centers
and routers. We are seeking certification from these third parties as to the
Year 2000 compliance status of their products. We anticipate that we will have
the certification of all relevant third parties in December 1999.

    The failure of any of our systems or systems maintained by third parties to
be Year 2000 compliant could:

    - cause us to incur major expenses to remedy any problems;

    - affect the availability and performance of our network; or

    - otherwise significantly damage our operations.

    Year 2000-related disruptions to our network could cause our users,
advertisers or e-commerce partners to become dissatisfied with our network or
could impose an unmanageable burden on our technical support staff. Any failure
by us to correct a major Year 2000 problem would have a material adverse effect
on our company.

RISKS RELATED TO LATIN AMERICA

OUR FUTURE SUCCESS DEPENDS UPON SUBSTANTIAL GROWTH IN USE OF THE INTERNET IN
LATIN AMERICA.

    The timing and the degree of our future success will depend on the continued
growth of the market for on-line content, services and e-commerce in Latin
America. The market in the region for our services has only recently begun to
develop and is evolving. The commercial potential for the Internet in Latin
America also remains uncertain. Major issues concerning the use of the Internet,
such as security, intellectual property rights, reliability, cost, ease of
deployment and administration, and quality of service, remain largely unresolved
and may adversely affect our growth and market acceptance.

                                       23
<PAGE>
    Each country in Latin America has its own telephone rate tariff regime
which, if too costly, may make consumers less likely to sign up for and access
the Internet. As a result of broad privatization and deregulation of the
telecommunications industry in Latin America and increased competition, tariffs
have been reduced recently in some countries. However, we cannot assure you that
this trend will continue. Unfavorable tariff developments could have a material
adverse effect on our company.

E-COMMERCE TRANSACTIONS IN LATIN AMERICA CONTINUE TO BE IMPEDED BY THE LACK OF
SECURE PAYMENT METHODS, HIGH CUSTOMS DUTIES AND UNRELIABLE PARCEL DELIVERY
SYSTEMS.

    Unlike in the United States, consumers and merchants in Latin America can be
held fully liable for credit card and other losses due to third-party fraud. As
secure methods of payment for e-commerce transactions have not been widely
adopted in Latin America, both consumers and merchants generally have a
relatively low confidence level in the integrity of e-commerce transactions. In
addition, many banks and other financial institutions have generally been
reluctant to give merchants the right to process on-line transactions due to
these concerns about credit card fraud. Unless consumer fraud laws in Latin
American countries are modified to protect e-commerce merchants and consumers,
and until secure, integrated on-line payment processing methods are fully
implemented across the region, our ability to generate revenues from e-commerce
may be limited, which could have a material adverse effect on our company.

    Heavy customs duties and taxes are imposed on deliveries of international
parcels in many countries in Latin America. Many countries also do not have
systems in place to ensure speedy and reliable delivery of parcels once they
have cleared customs. These problems may deter many merchants and consumers from
engaging in e-commerce transactions. For example, merchants who are familiar
with these barriers to the development of e-commerce may not seek to advertise
or sell their products and services until these problems are addressed. If
governmental authorities in Latin American countries fail to deregulate customs
duties, or if deregulation occurs slowly, our ability to generate meaningful
revenues from e-commerce will be reduced, which could have a material adverse
effect on our company.

ADVERSE LATIN AMERICAN POLITICAL AND ECONOMIC CONDITIONS COULD AFFECT OUR
FINANCIAL PERFORMANCE.

    We currently operate in Argentina, Brazil, Mexico, the United States and
Uruguay. We are planning to expand into Chile, Colombia and Venezuela in the
near future, and we are also considering other markets in Latin America. Our
financial performance and the market price for our common shares may be affected
generally by inflation, exchange rates and controls, price controls, interest
rates, changes in governmental economic policy, taxation and other political,
economic or other developments in or affecting the Latin American countries in
which we operate.

LOCAL CURRENCIES USED IN THE CONDUCT OF OUR BUSINESS ARE SUBJECT TO DEPRECIATION
AND VOLATILITY.

    The currencies of many countries in Latin America have experienced
substantial depreciation and volatility, particularly against the U.S. dollar,
in recent years. Currency movements, as well as higher interest rates, have
materially and adversely affected the economies of many Latin American
countries, including countries which account or are expected to account for a
significant portion of our revenues.

    Our reporting currency is the U.S. dollar. However, customers of our
connectivity services and some advertisers in Latin America may be billed in
local currencies. In Brazil, for example, commercial billing is required to be
in REAIS, the local currency. Our accounts receivable from these subscribers and
advertisers will decline in value if the local currencies depreciate relative to
the U.S. dollar. Similarly, any decline in the value of local currencies
relative to the U.S. dollar is likely to reduce the U.S. dollar prices that we
will be able to charge our advertisers. In addition, we may be subject to
exchange control

                                       24

regulations which might restrict our ability to convert local currencies into
U.S. dollars. Any imposition of exchange controls could adversely affect our
company.

RISKS RELATED TO OUR COMMON SHARES

MARKET PRICES OF, AND TRADING VOLUMES IN, OUR COMMON SHARES MAY BE VOLATILE.

    This offering constitutes the initial public offering of our common shares,
and no public market for our common shares currently exists. We cannot assure
you that an active trading market will develop or be sustained after the
offering is completed. The initial public offering price will be determined
through negotiations between us and the underwriters based on several factors
and may not be indicative of the market price for the common shares after the
offering.

    The market price of our common shares may be significantly affected by,
among others, the following factors:

    - our actual or anticipated results of operations;

    - new services or products offered, or new contracts entered into, by our
      company or our competitors;

    - changes in, or our failure to meet, securities analysts' expectations;

    - legislative and regulatory developments affecting the Internet industry;

    - developments in the Internet industry and technological innovations;

    - investor perceptions of investments relating to Latin America; and

    - general market conditions and other factors beyond our control.

    U.S. and non-U.S. stock markets have periodically experienced significant
price and volume fluctuations that have especially affected the market prices of
common shares of Internet companies. These changes have often been unrelated to
the financial performance of particular companies. These broad market
developments may also adversely affect the market price of our common shares.

WE WILL RETAIN COMPLETE DISCRETION AS TO THE USE OF THE NET PROCEEDS OF THIS
OFFERING.

    We intend to use the net proceeds from this offering for a broad range of
corporate purposes to support and accelerate the development of our company. We
will retain complete discretion in using the net proceeds, including uses with
which shareholders may disagree. Any failure to apply the net proceeds of this
offering in an effective manner could adversely affect our company.

OUR SHAREHOLDERS MAY FACE DIFFICULTIES IN PROTECTING THEIR INTERESTS BECAUSE WE
ARE A BRITISH VIRGIN ISLANDS COMPANY.

    Corporate governance matters for our company are principally determined by
our memorandum of association and articles of association and the International
Business Companies Act, 1984 (Cap. 291) of the British Virgin Islands. The
rights of shareholders and the fiduciary responsibilities of directors, officers
and controlling shareholders under British Virgin Islands law have not been
extensively developed, particularly when compared with statutes and judicial
precedents of most states and other jurisdictions in the United States. As a
result, our shareholders may have more difficulty in protecting their interests
in the case of actions by our directors, officers or controlling shareholders
than would shareholders of a corporation incorporated in a state or other
jurisdiction in the United States.

                                       25
<PAGE>
YOU MAY EXPERIENCE DIFFICULTY IN ENFORCING CIVIL LIABILITIES AGAINST OUR
COMPANY.

    We are a British Virgin Islands company, and a substantial portion of our
assets is located outside of the United States. In addition, most of our
directors and executive officers, as well as other persons controlling our
company, reside or are located outside of the United States. As a result, it may
not be possible for investors to effect service of process within the United
States upon us or these persons or to enforce judgments obtained against us or
these persons in U.S. courts predicated solely upon the civil liability
provisions of the U.S. federal or state securities laws. We have been advised by
Conyers Dill & Pearman, our British Virgin Islands counsel, that there is doubt
as to the enforceability in the British Virgin Islands in original actions or in
actions for enforcement of judgments of U.S. courts, of civil liabilities
predicated upon the U.S. federal or state securities laws. There is also doubt
as to enforceability of judgments of this nature in several of the jurisdictions
in which we operate and our assets are located.

FUTURE SALES OF OUR COMMON SHARES COULD ADVERSELY AFFECT MARKET PRICES OF OUR
COMMON SHARES.

    Upon the closing of this offering, we will have outstanding 38,574,460
common shares, or 39,804,460 common shares if the underwriters' over-allotment
option is exercised in full. Of these shares, the common shares sold in this
offering will be freely tradeable except for any shares purchased by our
"affiliates" as defined in Rule 144 under the Securities Act of 1933. Of the
remaining common shares held by our existing shareholders, 27,121,294 common
shares will be subject to 180-day "lock-up" agreements with the underwriters
and, in addition, will be eligible for sale only if registered or if they
qualify for an exemption from registration under the Securities Act of 1933.
After the 180-day lockup period, these shares may be sold in the public market,
subject to prior registration or qualification for an exemption from
registration and, in the case of shares held by affiliates, to compliance with
applicable volume restrictions. Some of our shareholders are entitled, pursuant
to contractual provisions providing for registration rights, to require our
company to register our securities owned by them for public sale. Sales of a
large number of shares could have an adverse effect on the market price of our
common shares.

YOU WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION.

    Investors purchasing our common shares in this offering will suffer
immediate and substantial dilution of their investment. The initial public
offering price per share will significantly exceed the net tangible book value
per share. You will, in other words, pay a higher price per share than the
amount of our total tangible assets, minus our total liabilities, divided by the
total number of outstanding shares. In addition, you and other investors
participating in this offering will provide approximately 60.7% of the total
equity contributions made to our company, but will own only approximately 21.3%
of our total outstanding shares. If we issue additional common shares in the
future for any reason, or if outstanding or future options or warrants to
purchase our common shares are exercised, you could suffer further dilution.

DATA REGARDING USAGE OF, AND GROWTH PROSPECTS FOR, THE INTERNET MAY NOT BE
ACCURATE.

    The general market and similar data in this prospectus relating to the
Internet industry in Latin America and the United States, including with respect
to projected increases in users of, and advertising and e-commerce on, the
Internet, have been based upon information published by or obtained from
independent market research firms, in each case, except as otherwise indicated.
These research firms include International Data Corporation and Forrester
Research. The market forecasts by these firms are based to a large extent upon
assumptions, including assumptions about the growing acceptance of the Internet
as a medium for commercial activity and continuing advances in computing and
telecommunications technology. We cannot assure you that these assumptions will
prove to be correct or, even if they do, that the forecasts will prove to be
accurate.

                                USE OF PROCEEDS

    The net proceeds from the sale of the common shares in this offering are
estimated to be approximately $89.0 million (after deduction of underwriting
discounts and estimated transaction expenses). This estimate is based on an
assumed initial public offering price of $12.00 per share, which is the
mid-point of the estimated range of offering prices presented on the cover page
of this prospectus. The term "net proceeds" represents the amount that we will
receive after payment of underwriting discounts and commissions and other
transaction expenses related to this offering.

    We also received net proceeds (after payment of a private placement fee to
the agent and transaction expenses) of $9.2 million from the private placement
of our Class B convertible preferred shares in mid-November 1999.

    We intend to use the net proceeds from this offering and the private
placement as follows:

       - approximately $48.0 million to fund our sales and marketing, and
         branding and advertising activities;

       - approximately $20.0 million to develop new services and products, and
         our network infrastructure;

       - approximately $1.3 million to pay dividends in respect of the Class A
         convertible preferred shares accrued as of the closing date of this
         offering; and

       - the balance for general corporate and working capital requirements,
         including strategic investments.

    We have not definitively allocated any portion of these net proceeds for the
above specified purposes. Instead, we will retain complete discretion in
applying the proceeds of this offering. Pending any use, we intend to invest the
net proceeds in short-term money market and other market-rate instruments.

                                DIVIDEND POLICY

    We have never declared or paid any cash dividends on our common shares. We
currently intend to retain our future earnings, if any, to fund the development
and growth of our business and, therefore, do not anticipate paying any cash
dividends on common shares in the foreseeable future.

    The declaration and payment of any dividends on our common shares, whether
in cash or shares, will be subject to the discretion of our board of directors.
We anticipate that any future dividends would be paid in U.S. dollars. Any
future determination to pay dividends, will depend on our results of operations,
financial condition, capital requirements, contractual restrictions and other
factors considered relevant by our board of directors.

                                    DILUTION

    Dilution is the amount by which the initial public offering price paid by
the purchasers of common shares in this offering exceeds the net tangible book
value per share after this offering. Net tangible book value per share is
determined by subtracting our total liabilities from the total book value of our
tangible assets and dividing the difference by the number of common shares
deemed to be outstanding on the date as of which the book value is determined.

    The pro forma net tangible book value deficit at September 30, 1999 has been
determined as follows (dollars in thousands):

</TABLE>

    Pro forma net tangible book value per share is determined by using
12,568,098 common shares outstanding on a pro forma basis and before giving
effect to this offering and the conversion of our Class A convertible preferred
shares into common shares. Pro forma as adjusted net tangible book value per
share is determined by using 38,574,460 common shares outstanding, which is the
sum of:

    - the common shares outstanding on a pro forma basis;

    - the 8,200,000 common shares to be sold in this offering; and

    - the 17,806,362 common shares issuable upon conversion of all of our
      outstanding Class A convertible preferred shares.

    The pro forma net tangible book value deficit of our shares at
September 30, 1999 was approximately $2.63 per share. After giving effect to the
receipt of the net proceeds of this offering based upon an initial public
offering price of $12.00 per share (which is the mid-point of the estimated
range of offering prices on the cover of this prospectus) and the conversion of
the Class A convertible preferred shares into common shares, our pro forma as
adjusted net tangible book value at September 30, 1999 would have been
$115.7 million, or $3.00 per share. These transactions represent an immediate
increase in net tangible book value of $5.63 per share to existing holders of
common shares and an immediate dilution of $9.00 per share to new public
investors. The following table illustrates this per share dilution:

</TABLE>

    If the underwriters' over-allotment option is exercised in full, the pro
forma as adjusted net tangible book value per common share after giving effect
to this offering would be $3.25 per share. After deducting underwriting
discounts and commissions and estimated transaction expenses, the increase in
the net tangible book value per share to existing shareholders would be $5.88,
and the dilution to new public investors would be $8.75 per share.

    After giving further effect to the conversion of all of our Class B
convertible preferred shares into common shares (which will automatically occur
on the date six months after the closing date of this

                                       31

offering), the pro forma as adjusted net tangible book value per common share
would be $3.39 per share and the dilution to new investors would be $8.61 per
share.

    After giving effect to the conversion of all of our Class B convertible
preferred shares into common shares (which will automatically occur on the date
six months after the closing date of this offering), the number of common shares
purchased by existing shareholders, including the holders of the converted Class
B convertible preferred shares, would increase to 31,485,572 shares, the total
consideration paid by them would increase to $72,854,000 and the average price
per share paid by them would increase to $2.31 per share.

    The above tables and calculations assume that none of the options
outstanding at November 1, 1999 have been or will be exercised prior to
completion of this offering and exclude common shares reserved for future
issuance under our 1999 share option plan. At November 1, 1999, there were
2,268,600 options outstanding to purchase a total of common shares with a
weighted average exercise price of $5.73 per share. To the extent that any of
these options are exercised, there will be further dilution to new investors.

                            SELECTED FINANCIAL DATA

    The following financial data should be read in conjunction with the
consolidated financial statements, the unaudited pro forma consolidated
financial information, "Summary Financial Data" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations" in this prospectus.

    The selected balance sheet data at December 31, 1997 and 1998 and
September 30, 1999 and the selected statement of operations data for the period
from July 16, 1997 (date of inception) through December 31, 1997, the year ended
December 31, 1998 and the nine months ended September 30, 1999 have been derived
from our audited consolidated balance sheets and statements of operations
included elsewhere in this prospectus. The statement of operations data for the
nine months ended September 30, 1998 have been derived from our unaudited
consolidated statement of operations included elsewhere in this prospectus. The
unaudited financial statements include all adjustments, consisting only of
normal recurring adjustments, which in the opinion of management, are necessary
for the fair presentation of our consolidated financial condition and results of
operations for those periods. Results of operations for the nine months ended
September 30, 1999 are not necessarily indicative of the results that may be
expected for the entire year or for any future period.

    The selected pro forma balance sheet data and the pro forma statement of
operations data at and for the nine months ended September 30, 1999 and at and
for the year ended December 31, 1998 have been derived from the unaudited pro
forma consolidated financial information included elsewhere in this prospectus.
The pro forma financial information reflects:

    - our recent acquisitions of retail dial-up access customers of IMPSAT
      Corporation in Argentina and Brazil and our pending acquisition of its
      retail dial-up access customers in Colombia from IMPSAT Corporation for an
      aggregate purchase price of $21.5 million and the related purchase by
      IMPSAT Corporation of 3,070,615 of our Class A convertible preferred
      shares for $21.5 million; and

    - the private placement in mid-November 1999 of 1,111,111 Class B
      convertible preferred shares for an aggregate purchase price of
      $10.0 million.

    The selected pro forma as adjusted balance sheet data give effect to the
sale of the common shares in, and the receipt of the net proceeds from, this
offering. We have assumed an initial public offering price of $12.00 per share,
which is the mid-point of the estimated range of offering prices presented on
the cover page of this prospectus. The pro forma as adjusted data also assume
that all of our outstanding Class A convertible preferred shares have been
converted into our common shares. The conversion will automatically occur upon
the closing of this offering.

    We prepare our financial statements and the pro forma financial statements
in U.S. dollars in accordance with generally accepted accounting principles in
the United States, which is commonly called "U.S. GAAP."

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

    The following discussion should be read in conjunction with our consolidated
financial statements, the unaudited pro forma financial information and the
other information appearing elsewhere in this prospectus.

OVERVIEW

    We are an Internet network providing country-specific and regional content
for Spanish- and Portuguese-speaking audiences in Latin America and the United
States. Recognizing that the countries in the Americas are diverse, we have
designed our network to consist of country Websites as well as a global Website.
We currently have country Websites for, and sales and content production offices
in, Argentina, Brazil, Mexico, the United States and Uruguay. We plan to
establish sales and content production offices in Colombia before the end of
1999, and sales and content production offices in Chile and Venezuela during
2000. By offering content and interactive resources designed to be responsive to
our users' preferences, we seek to make our network their "home on the Internet"
and, in so doing, to create communities of users, develop user loyalty and
increase traffic on our Websites. The launch of each country Website represents
a potential new community of users. By building substantial communities of
users, we are developing a platform for generating revenues from advertising,
branded retail dial-up Internet access, or "connectivity", service and, in the
future, e-commerce. We recently began to offer connectivity services in
Argentina and Brazil and expect to offer similar services in Colombia before the
end of 1999. We are also beginning to develop e-commerce for Spanish- and
Portuguese-speaking audiences in Latin America and the United States.

    We were incorporated in the British Virgin Islands, and commenced commercial
operations in Argentina, in 1997. For the period from inception through
October 1998, we focused our activities on developing our network of Websites
and opening content production and sales offices in Brazil, Mexico, the United
States and Uruguay.

    Prior to the commercial roll-out of our network of Websites in
November 1998, we did not generate meaningful revenues, but achieved growth in
terms of registered users and monthly page views by users. Since that time, we
have focused on developing our network to incorporate new content channels and
value-added and interactive resources, recruiting sales and marketing staff,
raising capital, preparing our first mass media-based branding and advertising
campaign and expanding our technological infrastructure. Our registered users
(meaning users who have provided personal information such as name, e-mail
address and address) grew from 54,132 persons in June 1998 to 291,567 persons in
July 1999. From June 1998 to July 1999, the number of pages viewed by our users
increased from 3.0 million to 21.0 million per month. On August 1, 1999, we
launched our first mass media-based branding and advertising campaign in
Argentina, Brazil, Mexico and Uruguay and, on September 9, 1999, in the United
States. In the first three months of this campaign, our registered users
increased by approximately 69% to 498,515 on October 31, 1999 and the number of
pages viewed per month by our users increased by over 250% to 73.9 million pages
in that month. In addition, we commenced measuring unique visitors in March
1999. The number of unique visitors has increased from 174,800 in March 1999 to
approximately 1.6 million in October 1999. We attribute this recent growth
principally to our media-based branding and advertising campaign and cannot
predict whether such growth will continue.

    In July 1999, we completed a private placement of 6,334,004 Class A
convertible preferred shares for a gross purchase price of $44.4 million in
cash, consisting of 5,477,088 shares sold for $38.4 million in cash and an
additional 856,916 shares to be issued on a quarterly basis through
January 2001 in exchange for $6.0 million in non-cash advertising time credits.
Strategic investors in the private placement included Hicks, Muse, Tate & Furst
Incorporated and the Cisneros Group of Companies (through IAMP (El Sitio)
Investments Ltd.) and GC Companies Inc. (through GCC Investments, LLC).

                                       35
<PAGE>
Some of our founders purchased $6.5 million of our Class A convertible preferred
shares in the private placement.

    In August 1999, we entered into a framework agreement with IMPSAT
Corporation, a provider of private networks of integrated data and voice
communications systems in a number of countries in Latin America, to acquire its
retail dial-up access customers in Argentina, Brazil and Colombia. Under this
agreement, we have acquired or will acquire these customers for an aggregate of
$21.5 million, which is based on a price of approximately $294 per subscriber.
IMPSAT Corporation will be purchasing a total of 3,070,615 Class A convertible
preferred shares for an aggregate purchase price of $21.5 million. The Argentine
and Brazilian acquisitions were consummated in November and October 1999,
respectively, and we expect to close the acquisition in Colombia before the end
of 1999. We are not acquiring the telecommunications infrastructure required to
provide connectivity services, which we intend to outsource from third-party
telecommunications providers--initially, under services agreements with
subsidiaries of IMPSAT Corporation under which they will provide us with
telecommunications infrastructure for a three-year term for agreed-upon fees.
Our connectivity customers subscribe to our dial-up operations by paying a
monthly fee to us in exchange for connectivity to the Internet.

    In August 1999, we also entered into an arrangement with TV Azteca, S.A. de
C.V., the second leading television network in Mexico, under which we issued to
TV Azteca 355,478 shares of our Class A convertible preferred shares, then
valued at approximately $2.5 million, in exchange for $3.5 million in
advertising time on TV Azteca. This advertising time will be made available over
a three-year period.

    In mid-November 1999, we completed a private placement of 1,111,111 Class B
convertible preferred shares for a purchase price of $10.0 million in cash, or
$9.00 per Class B convertible preferred share. Purchasers of the Class B
convertible preferred shares consisted of Intel Atlantic, Inc., a subsidiary of
Intel Corporation, and Latinvest Asset Management do Brasil, Ltda., an affiliate
of Globalvest Management Company, L.P. The Class B convertible preferred shares
have an annual dividend rate of 8%. Each Class B convertible preferred share
will automatically convert, on the date six months after the closing date of
this offering, into one common share. The difference between the initial public
offering price per common share and the $9.00 price per Class B convertible
preferred share will be amortized as a deemed dividend during the same six-month
period.

    We have a limited operating and financial history for you to use as a basis
for evaluating an investment in our common shares. We are subject to the risks,
uncertainties and problems frequently encountered by companies in early stages
of development, particularly companies in new and rapidly developing markets,
such as the Internet industry. Our historical results of operations are not
necessarily indicative of the results of operations to be expected in the
future.

INTRODUCTION TO RESULTS OF OPERATIONS

    NET REVENUES

    We expect to derive our future net revenues from three principal sources:

    - advertising on our network of Websites;

    - connectivity to the Internet; and

    - e-commerce.

    ADVERTISING.  To date, we have derived substantially all of our net revenues
from the sale of advertisements and sponsorships on our network. Advertising
revenues are received principally from:

    - advertising arrangements under which we receive fixed fees for banners
      placed on our Websites for specified periods of time;

    - reciprocal services arrangements, under which we exchange advertising
      space on our network for advertising or services from other parties;

                                       36
<PAGE>
    - sponsorship arrangements which allow advertisers to sponsor an area on our
      network in exchange for a fixed payment; and

    - Web design and Web hosting services.

As the Latin American Internet market continues to develop, we believe that an
increasing proportion of our advertising revenues will be derived from
cost-per-thousand impression-based arrangements, under which advertisers will
pay us a specified amount for every 1,000 times their advertisements are viewed
on our network. We expect that our revenues derived from Web design or hosting
activities for other companies will decline significantly beginning in the
fourth quarter of 1999. In future periods, we expect to outsource these
activities and, in any event, intend to offer these services only to customers
purchasing at least $120,000 in yearly advertising on our Websites.

    Advertising revenues are recognized ratably in the period in which the
advertisement is displayed, so long as no significant obligations remain and
collection of the resulting receivable is probable. To the extent that minimum
guaranteed impression levels are not met, we defer recognition of the
corresponding revenues until guaranteed levels are achieved. Payments received
from advertisers prior to displaying their advertisements on our network are
recorded as deferred revenues. Revenues from exclusive sponsorship arrangements
are also recognized ratably. Our contracts with advertisers and advertising
agencies range from one to twelve months in length.

    We have entered into reciprocal services arrangements with various media
companies, such as MGM Networks Latin America, pursuant to which we exchange
advertising on our network for advertising or other services from these media
companies. We do not receive any cash payments pursuant to these arrangements.
Revenues and expenses relating to these arrangements are recorded at the
estimated fair value of the goods or services received or the estimated fair
value of the advertisements given, whichever is more readily determinable.
Expenses are recorded when services are received, which is typically in the same
period as the advertisements are run on our network. These expenses are included
in our marketing and sales expenses.

    CONNECTIVITY.  We have recently taken steps to expand our revenue base
through our acquisitions of the retail dial-up access customers of IMPSAT
Corporation in Argentina and Brazil and our pending acquisition of its retail
dial-up access customers in Colombia. Under these acquisitions, we have a total
of approximately 66,000 dial-up access customers in Argentina and Brazil and
expect to acquire approximately 7,000 customers in Colombia. We expect to derive
revenues from monthly access fees charged to our dial-up access subscribers.
Approximately 70% of our dial-up access subscribers are expected to be billed on
a monthly basis to subscribers' credit cards, which should result in automatic
payment to us by the relevant credit card provider of the billed amounts.

    E-COMMERCE.  We currently do not derive revenues from e-commerce. We are
evaluating several joint venture opportunities with e-commerce merchants in the
United States and Latin America to develop electronic retail operations in the
flower, gifts, books, music and software and hardware businesses. We recently
added a "shopping channel" to our Websites, through which a limited offering of
books, flowers, music, gifts and technology products will be made available from
local and U.S.-based e-merchants. Despite our pending e-commerce initiatives, we
do not expect to derive meaningful revenues from e-commerce activities until at
least 2001.

    OPERATING EXPENSES

    Our principal operating costs and expenses consist of:

    - product, content and technology expenses;

    - marketing and sales expenses;

    - corporate, general and administrative expenses; and

    - depreciation and amortization expenses.

                                       37
<PAGE>
    PRODUCT, CONTENT AND TECHNOLOGY EXPENSES.  Product, content and technology
expenses consist of personnel costs associated with the development, testing and
upgrading of our network of Websites and systems, purchases of content and
specific technology, particularly software, and telecommunications links and
access charges. As a result of our recent acquisitions of the retail dial-up
access customers in Argentina and Brazil from IMPSAT Corporation and our pending
acquisition of its retail dial-up access customers in Colombia, we expect to
incur, in the future, significant expenses relating to telecommunications. In
connection with these acquisitions, we have entered into services agreements
with subsidiaries of IMPSAT Corporation under which, in exchange for an access
fee linked to a number of dial-up access customers and levels of usage, IMPSAT
Corporation will provide the connections and the telecommunication
infrastructure necessary for our users to connect to the Internet. We currently
estimate that the aggregate fee payable to subsidiaries of IMPSAT Corporation
for these services will be approximately $500,000 per month. Except for hardware
(which is depreciated), we expense product, content and technology costs and
telecommunications infrastructure as they are incurred. We believe that
increased investment in new and enhanced features and technology is critical to
attaining our strategic objectives and remaining competitive. Accordingly, we
intend to continue recruiting and hiring experienced product, content and
technology personnel and to make additional investments in product, content and
technology development. We expect that product, content and technology expenses
will continue to increase significantly in future periods.

    MARKETING AND SALES EXPENSES.  Our marketing and sales expenses consist
primarily of salaries and expenses of marketing and sales personnel,
commissions, and sales force and other marketing-related expenses including,
most significantly, our mass media-based branding and advertising activities. We
expect these marketing and sales expenses to continue to increase significantly
for the foreseeable future as a result of:

    - our mass media-based branding and advertising strategy; and

    - the expansion of our sales force and marketing personnel.

    CORPORATE, GENERAL AND ADMINISTRATIVE EXPENSES.  Corporate, general and
administrative expenses consist primarily of costs related to corporate
personnel, occupancy costs, general operating costs and corporate professional
fee expenses, such as legal and accounting fees. We expect that we will incur
additional corporate, general and administrative expenses as we hire additional
personnel and incur additional costs related to the growth of our business and,
after this offering, our operation as a public company. Accordingly, we
anticipate that these expenses will continue to increase significantly in future
periods.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expenses
consist primarily of depreciation of servers and other computer equipment,
office furniture and leasehold improvements. Investments in property, plant and
equipment are recorded at cost and depreciated using the straight-line method
over the following estimated useful lives:

- - computers, software and other equipment                     3 years

</TABLE>

    As a result of our recent acquisitions of retail dial-up access customers of
IMPSAT Corporation in Argentina and Brazil and our pending acquisition of its
retail dial-up access customers in Colombia, we expect to incur significant
amortization expense related to intangible assets, consisting primarily of the
newly acquired customer base. The aggregate $21.5 million purchase price for the
acquisitions of these retail dial-up access customers has been allocated
principally to this intangible asset. This intangible asset will be amortized
over the next five years on a straight-line basis and, as such, will be
reflected as an expense in our statement of operations in future periods. To the
extent that we fail to retain this customer base during this period, this
intangible asset could be deemed to be impaired, in which case

                                       38
<PAGE>
an amount in excess of the anticipated amortization expense would be charged to
our results of operations and could result in substantially increased losses or,
in later years, reduced profitability. As a result, our future financial
performance could be materially and adversely affected if we are not successful
in preserving and developing our newly acquired connectivity customer base.

    SHARE-BASED COMPENSATION.  Our share-based compensation expense relates to
share options granted in August and September 1999. These options were granted
at an exercise price based on the purchase price paid by investors in our July
1999 private placement of Class A convertible preferred shares. Because this
exercise price is well below the initial public offering price for this
offering, we recorded total deferred share-based compensation expense of
$7.8 million, which we will amortize over the respective three-year vesting
periods for these options. See note 11 to our consolidated financial statements.
The total deferred share-based compensation amount and the expense for future
periods may increase depending upon the exercise prices and other terms for
subsequent grants of options. See note 14 to our consolidated financial
statements.

    OTHER INCOME (EXPENSE)

    Other income (expenses) consists primarily of interest expense, net of
interest earned, foreign exchange losses, net of any gains, and other
miscellaneous income and expense items. As a result of the net proceeds of the
offering, we expect that for the foreseeable future our interest income will
exceed our interest expense. Immediately after this offering most of our assets
will be in cash or cash equivalents, which we expect to principally maintain in
U.S. dollars. As our assets in each country of operation increase, so will our
exposure to foreign exchange losses on the translation of assets into U.S.
dollars.

    NET LOSSES

    We have incurred net losses and have experienced negative cash flow from
operations in each quarterly and annual period since our inception. Our overall
strategy is to develop our position as a full-service Internet network providing
country-specific content, connectivity services and e-commerce targeting
Spanish- and Portugese-speaking audiences in Latin America and the United
States. This strategy contemplates that we will make significant expenditures
for, among other things, marketing and sales, equipment, customer support and
personnel. This strategy also envisions that we may make significant investments
involving acquisitions, strategic relationships and joint ventures. Because of
this strategy, we expect that our net losses and negative cash flows from
operations on a quarterly and annual basis will increase significantly for at
least the next several years.

HISTORICAL RESULTS OF OPERATIONS

NINE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO NINE MONTHS ENDED
SEPTEMBER 30, 1998

    Our results of operations for the nine months ended September 30, 1999 were
characterized by increased expenses that more than offset revenue growth during
the period. We recorded a net loss of $13.9 million for the nine months ended
September 30, 1999, compared to a net loss of $1.8 million for the corresponding
period of 1998. During the first nine months of 1999, in addition to the
continued development of quality, content and interactive resources, we expanded
our operations and hired additional personnel to support the roll-out of offices
and Websites in Brazil, Mexico and the United States and the launch of our first
mass media-based branding and advertising campaign. We plan to establish new
sales and content production offices in Chile and Venezuela during 2000. We have
recently acquired a total of approximately 66,000 retail dial-up access
customers from IMPSAT Corporation in Argentina and Brazil, and expect to acquire
approximately 7,000 customers in Colombia by the end of 1999. We anticipate that
these recent developments will contribute to an increase in our revenues in
future periods.

                                       39
<PAGE>
    NET REVENUES

    Our net revenues increased by 146% to $1.5 million for the nine months ended
September 30, 1999 from $609,000 for the corresponding period in 1998. Of our
net revenues for the first nine months of 1999, approximately 78% was comprised
of advertising and the balance to Web design or hosting services. We expect that
our revenues derived from Web design or hosting activities for other companies
will decline significantly in the fourth quarter of 1999. In future periods, we
expect to outsource these activities and, in any event, will offer these
services only to customers who agree to purchase at least $120,000 in yearly
advertising on our Websites. Although most of our advertising revenues are
currently derived from fixed banners and page sponsorships, we believe that an
increasing portion of our advertising revenues will be derived from
cost-per-thousand impression-based arrangements. Under these arrangements
advertisers pay us a specified amount for every 1,000 times their advertisements
are viewed on our network.

    We attribute the increase in advertising revenues principally to the growth
of our network in terms of registered users and page views together with the
expansion of our marketing and sales force. Of these revenues 47% was derived
from Argentina, 22% from Mexico and 30% from Uruguay, as our operations in other
countries were still in the early stages of operations. In the future, we also
expect to derive significant revenues from Brazil, Mexico and the United States
where we have launched commercial operations during 1999. In the nine months
ended September 30, 1999, our largest client, TV Azteca, accounted for 13% of
total net revenues. During this period, 36% of our total revenues was derived
from reciprocal services arrangements compared to 22% of total net revenues in
the corresponding period in 1998. We do not receive any cash payments from these
arrangements.

    COSTS AND EXPENSES

    PRODUCT, CONTENT AND TECHNOLOGY EXPENSES.  Our product, content and
technology expenses increased to $3.2 million for the nine months ended
September 30, 1999 from $848,000 for the corresponding period in 1998. Our
product, content and technology expenses as a percentage of revenues increased
to 209% for the nine months ended September 30, 1999 from 139% in the
corresponding period in 1998. The period-to-period increase was principally
attributable to:

    - an increase in personnel costs relating to the development of content and
      technological support to $2.2 million in the nine months ended
      September 30, 1999 from $600,000 in the corresponding period in 1998;

    - an increase in expenses for telecommunications links to $385,000 in the
      nine months ended September 30, 1999 from $165,000 in the corresponding
      period in 1998; and

    - an increase of third-party content expenses to $130,000 in the nine months
      ended September 30, 1999 from no such expense in the corresponding period
      in 1998.

    We believe that continued development of, and increased investment in, new
and enhanced features and technology is critical to attaining our strategic
objectives and remaining competitive. Accordingly, we intend to continue
recruiting and hiring experienced product, content and technology personnel and
to make additional investments in product, content and technology development.
We expect that product, content and technology expenses will continue to
increase significantly in future periods.

    MARKETING AND SALES EXPENSES.  Our marketing and sales expenses increased to
$7.2 million for the nine months ended September 30, 1999 from $320,000 for the
corresponding period in 1998. Our marketing and sales expenses as a percentage
of net revenues increased to 470% for the nine months ended September 30, 1999
from 53% in the corresponding period in 1998. This increase was principally
attributable to:

    - $5.9 million in costs of our initial mass media-based branding and
      advertising campaign; and

                                       40
<PAGE>
    - an increase in marketing and sales personnel costs to $784,000 in the nine
      months ended September 30, 1999 from $34,000 in the corresponding period
      in 1998, due mainly to opening or expanding offices in Mexico, Brazil and
      the United States.

    We expect these sales expenses to continue to increase significantly for the
foreseeable future as a result of:

    - our mass media-based branding and advertising strategy; and

    - the expansion of our sales force and marketing personnel.

    CORPORATE, GENERAL AND ADMINISTRATIVE EXPENSES.  Our corporate, general and
administrative expenses increased to $3.7 million for the nine months ended
September 30, 1999 from $1.1 million for the corresponding period in 1998. Our
corporate, general and administrative expenses as a percentage of net revenues
increased to 245% for the nine months ended September 30, 1999 from 188% in the
corresponding period in 1998. This increase was principally attributable to:

    - an increase in corporate and administrative personnel costs to
      $1.3 million in the nine months ended September 30, 1999 from $320,000 in
      the corresponding period in 1998, which resulted primarily from the
      expansion of our network and financing activities; and

    - an increase in overhead costs to support the expansion of our business
      activities.

    We expect that we will incur additional corporate, general and
administrative expenses as we hire additional personnel and incur additional
costs related to the growth of our business. Accordingly, we anticipate that
these expenses will continue to increase significantly in future periods.

    DEPRECIATION AND AMORTIZATION.  Our depreciation and amortization expenses
increased to $336,000 for the nine months ended September 30, 1999 from $59,000
for the corresponding period in 1998. Our depreciation and amortization expenses
as a percentage of net revenues increased to 22% for the nine months ended
September 30, 1999 from 9.7% in the corresponding period in 1998. This increase
was principally attributable to an increase of $1.7 million in fixed assets
(principally servers and personal computers).

    As a result of our acquisitions of retail dial-up access customers of IMPSAT
Corporation in Argentina and Brazil and our pending acquisition of its retail
dial-up access customers in Colombia, we expect to incur significant
amortization expense related to intangible assets, consisting primarily of this
newly acquired customer base.

    SHARE-BASED COMPENSATION.  We incurred share-based compensation expense of
$499,000 for the nine months ended September 30, 1999. This amount represents
the amortization in this period of our total deferred share-based compensation
relating to share options granted in August and September 1999. See notes 11 and
14 to our consolidated financial statements.

    OTHER INCOME (EXPENSE)

    Other income (expense), which consists of net interest income (expense),
foreign exchange gain or loss, and other income (expense), net, consisted of
income of $266,000 for the nine months ended September 30, 1999 compared with a
loss of $30,000 for the corresponding period in 1998. This change resulted
primarily from interest income earned on the proceeds of the July 1999 private
placement. We expect that for the foreseeable future our interest income will
exceed our interest expense. As our assets in each country of operation
increase, so will our exposure to foreign exchange losses on the translation of
assets into U.S. dollars.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO PARTIAL YEAR 1997 (FROM INCEPTION IN
JULY 1997 THROUGH DECEMBER 31, 1997)

    Following our inception in July 1997 until the roll-out of our network of
country Websites during 1998, we concentrated on the development of quality
content and interactive resources in Spanish, and

                                       41
<PAGE>
on market testing to understand users' preferences. As a result, our results of
operations for 1998 were characterized by increasing expenses and mostly flat
revenues on a quarter-to-quarter basis. We recorded a net loss of $3.5 million
for 1998, compared to a net loss of $1.0 million for 1997. Our results of
operations for 1997 reflect a partial year consisting of six months.

    NET REVENUES

    Our net revenues increased 192% to $780,000 for 1998 from $267,000 for
partial year 1997. The increase in revenues resulted from the expansion of our
marketing efforts and sales force, as well as the increase in the number of
channels and services available on our network. For 1998, we had four customers,
Arcor S.A., Compaq Corporation, IMPSAT S.A. and Antel (Uruguay), which each
exceeded 10% of total revenues and in the aggregate represented 72% of total
revenues. By contrast, for partial year 1997, we had five customers, Miniphone,
Compaq Corporation, Arcor S.A., Telam S.A., and IMPSAT S.A., which each exceeded
10% of total revenues and in the aggregate represented 89% of total revenues.
Non-cash reciprocal services arrangements accounted for approximately 23% of our
total revenues in 1998 as compared with approximately 14% for partial year 1997.

    COST AND EXPENSES

    PRODUCT, CONTENT AND TECHNOLOGY EXPENSES.  Our product, content and
technology expenses increased to $1,556,000 for 1998 from $221,000 for partial
year 1997. Our product, content and technology expenses as a percentage of net
revenues increased to 200% for 1998 from 83% for partial year 1997. The
year-to-year increase was principally attributable to:

    - an increase in personnel costs dedicated to the development of content and
      technological support to $1.1 million in 1998 from $167,000 in partial
      year 1997; and

    - an increase in expenses for telecommunications links for our network to
      $284,000 in 1998 from $30,000 in partial year 1997.

    MARKETING AND SALES EXPENSES.  Our marketing and sales expenses increased to
$674,000 for 1998 from $142,000 for partial year 1997. Our marketing and sales
expenses as a percentage of revenues increased to 86% for 1998 from 53% for
partial year 1997. The year-to-year increase was principally attributable to:

    - an increase in personnel costs dedicated to marketing and sales to
      $274,000 in 1998 from $7,000 in partial year 1997; and

    - an increase in advertising expenses and sales commissions to $209,000 in
      1998 from $29,000 in partial year 1997.

    CORPORATE, GENERAL AND ADMINISTRATIVE EXPENSES.  Our corporate, general and
administrative expenses increased to $1.9 million for 1998 from $727,000 for
partial year 1997. Our corporate, general and administrative expenses as a
percentage of net revenues amounted to 249% for 1998 from 272% for partial year
ended 1997. The year-to-year increase was principally attributable to:

    - an increase in personnel costs in corporate and administrative functions
      to $480,000 in 1998 from $61,000 in partial year 1997; and

    - increases to $627,000 from $362,000 in professional fees, to $373,000 from
      $104,000 in rent and utilities and to $215,000 from $40,000 in travel and
      entertainment expenses.

                                       42
<PAGE>
    DEPRECIATION AND AMORTIZATION.  Our depreciation and amortization expenses
increased to $107,000 for 1998 from $81,000 for partial year 1997. However, our
depreciation and amortization expenses as a percentage of net revenues decreased
to 14% for 1998 from 30% for partial year 1997. The absolute increase in these
expenses was principally attributable to an increase of $508,000 in fixed assets
(principally servers and personal computers). The relative decrease in
depreciation and amortization expenses was attributable to a more substantial
increase in net revenues when compared with the absolute increase in these
expenses.

    OTHER INCOME (EXPENSE).

    Other expenses decreased to $20,000 for 1998 from $110,000 for partial year
1997. This decrease primarily reflected a decrease in interest expense in 1998
due to a decrease in the debt.

QUARTERLY RESULTS OF OPERATIONS

    The following tables set forth unaudited consolidated statement of
operations data for each of the seven quarters ended September 30, 1999. This
data has been derived from unaudited interim consolidated financial statements
prepared on the same basis as the audited consolidated financial statements
contained in this prospectus. In the opinion of management, this data includes
all adjustments, consisting only of normal recurring adjustments, that are
considered necessary for a fair presentation of this information when read in

    The results of operations for any quarter are not necessarily indicative of
the results of operations for any future period. In particular, because of our
limited operating and financial history, we have limited meaningful financial
data to estimate revenues and operating expenses.

OVERVIEW OF RESULTS OF OPERATIONS FOR NEWLY-ACQUIRED CONNECTIVITY OPERATIONS

    We have acquired IMPSAT Corporation's retail dial-up access customers in
Argentina and Brazil and are in the process of acquiring its retail dial-up
access customers in Colombia. The aggregate purchase price of these three
acquisitions is $21.5 million. As a result of these acquisitions, we recently
began to provide connectivity services in Argentina and Brazil and expect to
provide connectivity services in Colombia by the end of 1999. In connection with
these acquisitions, we have acquired approximately 66,000 retail dial-up access
customers in Argentina and Brazil and expect to acquire an aggregate of
approximately 7,000 dial-up customers in Colombia. We hired a total of 48
employees who previously worked for IMPSAT Corporation in Argentina and Brazil
and expect to hire an additional

                                       43
<PAGE>
five employees from IMPSAT Corporation in Colombia. These employees will perform
tasks which they previously performed for IMPSAT Corporation and which are not
currently performed by our employees. Because of the significance of these
acquisitions relative to our company's current assets and results of operations,
we have included the following brief discussion of the results of operations for
these acquisitions for 1998 and for the nine months ended September 30, 1999.

    The stand-alone financial information for these businesses included in this
prospectus was derived from IMPSAT Corporation's accounting records and based
upon the estimates of IMPSAT Corporation's management. This discussion should be
read in conjunction with the stand-alone audited financial information for the
acquired businesses and the unaudited pro forma consolidated financial
information included elsewhere in this prospectus. The historical results of
operations of these businesses are not necessarily indicative of the results of
operations to be expected in the future. However, in the brief period (since
October 7, 1999) during which we have provided connectivity services to our
retail dial-up access customers, we have generated net revenues and incurred
costs and expenses which are consistent with those reflected in the audited
financial information for the acquired dial-up access businesses included in
this prospectus.

NINE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO NINE MONTHS ENDED
SEPTEMBER 30, 1998

    NET REVENUES.

    For the three dial-up access businesses of IMPSAT Corporation, total net
revenues decreased to $10.0 million for the nine months ended September 30, 1999
from $12.1 million for the corresponding period in 1998.

    In Argentina, net revenues for the dial-up access business increased to
$2.9 million for the nine months ended September 30, 1999 from $2.3 million for
the corresponding period in 1998. This increase resulted from the following
factors:

    - an increase in paying subscribers to 15,646 at September 30, 1999 from
      13,223 at September 30, 1998; and

    - a partially offsetting decline in the average gross subscription fee per
      customer to $24.80 for the month of September 1999 from $33.29 for the
      month of September 1998.

The number of paying subscribers in Argentina increased by 36% during the course
of the nine months ended September 30, 1999 (as measured from the beginning to
the end of such nine-month period) as compared with a 67% increase during the
course of the corresponding period of 1998.

    In Brazil, net revenues for the dial-up access business decreased to
$5.8 million for the nine months ended September 30, 1999 from $8.0 million for
the corresponding period in 1998. This decrease resulted from the following
factors:

    - a decline in the average gross subscription fee per customer (in U.S.
      dollar terms) to $12.39 for the month of September 1999 from $22.19 for
      the month of September 1998, which decline was largely due to a 63%
      decline in the value of the Brazilian REAL to 1.94 REAIS per U.S. dollar
      at September 30, 1999 from 1.19 REAIS per U.S. dollar at September 30,
      1998; and

    - a partially offsetting increase in paying subscribers to 55,449 at
      September 30, 1999 from 48,960 at September 30, 1998.

The number of paying subscribers in Brazil increased by 14% during the course of
the nine months ended September 30, 1999 (as measured from the beginning to the
end of such nine-month period) as compared with a 57% increase during the course
of the corresponding period of 1998.

    In Colombia, net revenues for the dial-up access business decreased to
$1.4 million for the nine months ended September 30, 1999 from $1.7 million for
the corresponding period in 1998. This decrease resulted from the following
factors:

                                       44
<PAGE>
    - a decline in the average gross subscription fee per customer (in U.S.
      dollar terms) to $19.95 for the month of September 1999 from $25.80 for
      the month of September 1998, partially due to a 29.3% decline in the value
      of the Colombian PESO to 2005 PESOS per U.S. dollar at September 30, 1999
      from 1550 PESOS per U.S. dollar at September 30, 1998; and

    - a decrease in paying subscribers to 6,817 at September 30, 1999 from 6,899
      at September 30, 1998.

    We anticipate that our connectivity services business will experience
declining average subscription fees in the future. We cannot predict the rate of
decline. However, we believe that our connectivity services business will
benefit from our overall mass media-based branding and advertising campaigns. We
also intend to dedicate significant resources to increasing our base of
connectivity customers. Accordingly, we believe that the rate of growth in
paying subscribers should increase within the next few months. We also
anticipate that the cost of telecommunications infrastructure services provided
by third parties should decrease in future periods. We believe that the retail
dial-up access businesses were not core businesses of IMPSAT Corporation and, as
a result, did not receive managerial focus during the months leading up to our
acquisition of these businesses. We cannot predict the actual rate of increase
in paying customers or whether any increase will occur or, if it occurs, will
continue.

    DIRECT COSTS AND EXPENSES.

    The principal direct costs and expenses of our dial-up access businesses
consist of product, content and technology costs and marketing and sales
expenses. These costs and expenses together include costs of telecommunications
infrastructure to provide the services, personnel costs, outsourced product
support, such as a 24-hour help desk, and administrative costs. Direct costs and
expenses for these businesses decreased to $8.9 million for the nine months
ended September 30, 1999 from $10.3 million for the corresponding period in
1998. Direct costs and expenses as a percentage of total net revenues was 88%
for the nine months ended September 30, 1999 and 85% for the corresponding
period in 1998.

    EXCESS OF NET REVENUES OVER DIRECT COSTS AND EXPENSES.

    Excess of net revenues over direct costs and expenses decreased to
$1.2 million for the nine months ended September 30, 1999 from $1.8 million for
the corresponding period in 1998.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO PARTIAL YEAR ENDED DECEMBER 31, 1997.

    NET REVENUES.  Total net revenues for the three dial-up access businesses of
IMPSAT Corporation increased to $16.5 million for 1998 from $11.5 million in
partial year 1997. Total paying subscribers increased to 68,646 at December 31,
1998, representing a 40% increase from 48,909 at December 31, 1997.

    In Argentina, net revenues for the dial-up access business increased to
$3.0 million in 1998 from $2.6 million for partial year 1997. This increase
resulted from the following factors:

    - an increase in paying subscribers to 14,329 at December 31, 1998 from
      6,626 at December 31, 1997; and

    - a partially offsetting decline in the average gross subscription fee per
      customer to $37.49 for the year ended December 1998 from $66.99 for
      partial year 1997.

    In Brazil, net revenues for the dial-up access business increased to
$11.4 million for 1998 from $7.0 million for partial year 1997. This increase
resulted from the following factors:

    - an increase in paying subscribers to 48,603 at December 31, 1998 from
      31,119 at December 31, 1997;

    - a partially offsetting decline in the average gross subscription fee (in
      U.S. dollar terms) per customer to $23.31 for December 1998 from $27.79
      for December 1997, partially due to a 8.0%

                                       45
<PAGE>
      decline in the value of the Brazilian REAL to 1.21 REAIS per U.S. dollar
      at December 31, 1998 from 1.12 REAIS per U.S. dollar at December 31, 1997.

    In Colombia, net revenues for the dial-up access business increased to
$2.1 million for 1998 from $1.8 million for partial year 1997. This decrease was
primarily attributable to the following factors:

    - a decline in the average gross subscription fee per customer to $25.80 for
      December 1998 from $32.43 for December 1997 partially due to a 20% decline
      in the value of the Colombian PESO to 1,550 PESOS per U.S. dollar at
      December 31, 1998 from 1,295 PESOS per U.S. dollar at December 31, 1997;
      and

    - a decrease in paying subscribers to 5,714 at December 31, 1998 from 6,122
      at December 31, 1997.

    DIRECT COSTS AND EXPENSES.  Direct costs and expenses for these businesses
increased to $14.1 million for 1998 from $9.7 million for partial year 1997.
Direct costs and expenses as a percentage of total net revenues was 86% for 1998
as compared to 84% in partial year 1997.

    EXCESS OF NET REVENUES OVER DIRECT COSTS AND EXPENSES.  Due to the factors
noted above, the excess of net revenues over direct costs and expenses was
$2.4 million for 1998 as compared to $1.8 million for partial year 1997.

LIQUIDITY AND CAPITAL RESOURCES

    We continue to be a company in an early stage of operations. We have
substantial liquidity and capital resource requirements, but limited sources of
liquidity and capital resources. We have generated net losses and negative cash
flows from our inception and anticipate that we will experience substantial and
increasing net losses and negative cash flows for at least the next several
years. As we implement our strategy and seek to take advantage of our market
opportunity, we anticipate that our liquidity and capital resource requirements
will increase significantly.

    From our inception to date, we have relied principally upon equity
investments to support the development of our business. We expect to continue to
rely mainly on further equity offerings to provide financing, including this
offering which constitutes, by far, the major capital-raising initiative in our
history.

    We received total capital contributions of approximately $1.2 million in
1997 and $4.1 million in 1998. In the nine months ended September 30, 1999 we
received total capital contributions in cash of $36.8 million, which consisted
primarily of the proceeds of a private placement of 6,334,004 Class A
convertible preferred shares for a total purchase price of $44.4 million. This
private placement consisted of 5,477,088 shares sold for $38.4 million in cash
in July 1999 and 856,916 shares to be issued on a quarterly basis through
January 2001 in exchange for $6.0 million in non-cash advertising time credits.
In addition, in connection with our recent acquisitions of retail dial-up access
customers from IMPSAT Corporation in Argentina and Brazil and our pending
acquisition of its retail dial-up access customers in Colombia, IMPSAT
Corporation will purchase approximately $21.5 million of our Class A convertible
preferred shares. Furthermore, in connection with our arrangement with TV
Azteca, S.A. de C.V., we issued to TV Azteca 355,478 Class A convertible
preferred shares in exchange for approximately $3.5 million of advertising time,
which will be made available over a three-year period beginning on July 1999.

    As part of the July 1999 private placement, we entered into an agreement
with Washburn Enterprises, an affiliate of one of our shareholders, under which
we also agreed to purchase at least $4.0 million of advertising time on the
media networks owed by Washburn's affiliate Ibero-American Media Partners
II Ltd. and its affiliates, and Washburn agreed that it and its affiliates would
purchase as least $2 million of advertising time on our network, all during the
period through January 2001.

    In mid-November 1999, we completed a private placement of 1,111,111 Class B
convertible preferred shares for a purchase price of $10.0 million in cash, or
$9.00 per Class B convertible

                                       46
<PAGE>
preferred share. Purchasers of the Class B convertible preferred shares
consisted of Intel Atlantic, Inc., a subsidiary of Intel Corporation, and
Latinvest Asset Management do Brasil, Ltda., an affiliate of Globalvest
Management Company, L.P. Each Class B convertible preferred share will
automatically convert, on the date six months after the closing date of this
offering, into one common share. The difference between the initial public
offering price per common share and the $9.00 price per Class B convertible
preferred share will be amortized as a deemed dividend during the same six-month
period.

    Net cash used in operating activities was $11.2 million for the nine months
ended September 30, 1999, $3.2 million for the year ended December 31, 1998 and
$875,000 for the partial year ended December 31, 1997. We have experienced and
expect to continue to experience significant negative cash flows from operating
activities. Net cash used in operating activities resulted primarily from our
net operating losses.

    Net cash used in investing activities was $1.5 million for the nine months
ended September 30, 1999, $733,000 for the year ended December 1998 and $261,000
for the partial year ended December 31, 1997. Net cash used in investing
activities resulted primarily from purchases of capital assets.

    Net cash provided by financing activities was $36.8 million for the nine
months ended September 30, 1999, $4.1 million for the year ended December 31,
1998 and $1.2 million for the partial year ended December 31, 1997. Net cash
provided by financing activities consisted primarily of the net proceeds from
short-term borrowings and the sale of our common shares.

    We expect to make capital expenditures of approximately $3.0 million in
1999, including $1.5 million spent in the nine months ended September 30, 1999,
and a total of approximately $5.0 million for 2000 and 2001. The capital
expenditures in 1999 principally consist of purchases of, or investments in,
technical equipment. We expect that our capital expenditures will increase
significantly in the future as we make technological improvements to our network
of Websites and technical infrastructure and enter into strategic joint ventures
or acquisitions.

    We expense many of our expenditures related to improvements to our Websites
such as new channels and interactive features. These expenditures are estimated
to be approximately $4.0 million during 2000. We expect to spend a total of
$1.0 million in 2001 on the development of content with respect to our country
Websites for Chile, Colombia and Venezuela. We have not projected any
expenditures related to business combinations other than content and marketing
alliances, which are included in the product, content and technology expenses
and the marketing and sales expenses.

    Our liquidity and capital resource requirements will depend on numerous
factors, including:

    - market acceptance of our services and products;

    - the level of resources that we devote to investments in our network;

    - marketing and sales of our services and products; and

    - our branding and advertising activities.

    We believe that the net proceeds of this offering and of our mid-November
1999 private placement of our Class B convertible preferred shares, together
with our current cash and cash equivalents balance of $24.4 million at
September 30, 1999 (which includes the remaining unused net proceeds from our
July 1999 private placement of our Class A convertible preferred shares) will be
sufficient to meet our liquidity and capital resource requirements through early
2002. We expect to require up to an additional $50 million of additional
financing during the period through 2003, when we expect to achieve
profitability. If our cash resources prove to be insufficient to satisfy these
requirements, we may seek to sell additional equity or debt securities or to
obtain a credit facility. The sale of additional equity or convertible debt
securities could result in additional dilution to our shareholders. The
incurrence of indebtedness would result in increased fixed obligations and most
likely would subject us to covenants that would restrict our operations. We
cannot assure you that financing will be available in amounts or on terms
acceptable to us, if at all.

YEAR 2000 COMPLIANCE

    Many currently installed computer systems and software products are coded to
accept or recognize only two digit entries in the date code field. These systems
and software products will need to accept four digit entries to distinguish 21st
century dates from 20th century dates. As a result, computer systems and/or
software used by many companies and governmental agencies may need to be
upgraded to comply with such Year 2000 requirements or risk system failure or
miscalculations which may cause disruptions to normal business activities.

    We are in the process of conducting an internal review to ensure that our
services and products are Year 2000 compliant. Year 2000 problems may originate
within our own systems and products or within the systems of our third party
suppliers or our customers. Some of our non-information technology systems, such
as equipments or machinery, may also be affected by Year 2000 problems.

    Our internal verification process consists of:

    - component inventory and assessment, including vendor and third party
      evaluation;

    - component remediation;

    - component testing;

    - system testing; and

    - contingency planning.

    We have conducted an inventory, and developed testing procedures, for all
software and other systems that we believe might be affected by Year 2000
issues. We have tested our computers, servers and other equipment. We have
sought written confirmation from each of our third-party suppliers and service
providers as to their respective readiness. We expect to complete upgrades and
testing by the end of 1999. We also expect to receive confirmation as to Year
2000 compliance from all key vendors and suppliers in December 1999. In
connection with our acquisitions of the retail dial-up access customers of
IMPSAT Corporation in Argentina and Brazil and our pending acquisition of its
retail dial-up access customers in Colombia, we are in the process of verifying
Year 2000 compliance of these businesses.

    We have also identified and have begun assessing non-information technology
embedded systems such as voice mail, office security, fire prevention and other
systems. We generally believe that our non-information technology embedded
systems do not present significant Year 2000 issues.

    To date, we have spent an immaterial amount on Year 2000 compliance issues,
but may incur up to approximately $350,000 in connection with identifying and
solving any Year 2000-related problems. We anticipate that most of our expenses
will relate to personnel costs associated with time spent by employees in the
assessment process and Year 2000 compliance matters.

    As discussed above, we are engaged in an ongoing Year 2000 assessment and
have developed no contingency plans to address the worst-case scenario that
might occur if the technologies we are dependent on actually are not Year 2000
compliant. The results of our Year 2000 simulation testing and the responses
received from all third-party suppliers and service providers will be taken into
account in determining the need for, and the nature and extent of, any
contingency plans.

    To the extent that our assessment is finalized without identifying any
additional material non-compliant information technology systems operated by us
or by third parties, the most reasonably likely worst case Year 2000 scenario is
a systemic failure beyond our control, such as a prolonged communications or
electrical failure. Any failure of this type could prevent us from accessing our
network, or change the behavior of advertising customers or persons accessing
our network. We believe that the primary business risks, in the event of such
failure, would include but not be limited to, lost advertising revenues,
increased operating costs, loss of customers or persons accessing our network,
and other business interruptions of a material nature, as well as claims of
mismanagement, misrepresentation or breach of contract.

MARKET RISKS

    We have not had meaningful interest rate exposure because we have maintained
small debt balances to date. Our Class A convertible preferred shares, which
carried an annual dividend rate of 8%, will be automatically converted into
common shares upon completion of this offering. We will pay accumulated
dividends in cash on or about the date of conversion. Our Class B convertible
preferred shares will also carry an annual dividend rate of 8%. We should not,
however, experience significant interest rate risks until such time as we have
material balances of indebtedness or preferred shares.

    Our principal foreign currency exposure has related to our asset base, which
has consisted principally of monetary assets and liabilities, in the countries
in which we operate. Our company's asset base in countries with foreign currency
exposures is summarized as follows:

</TABLE>

    Our subsidiaries have generally used the U.S. dollar as their functional
currency because the sale of advertising has historically been priced and billed
in U.S. dollars. As a result, the financial statements of the subsidiaries have
been remeasured, or translated into U.S. dollars. The effects of foreign
currency transactions and of remeasuring our subsidiaries' financial condition
and results of operations into U.S. dollars have been included as net gain or
loss on foreign exchange. However, our Brazilian subsidiary uses the REAL as its
functional currency and, as such, the effects of foreign currency transactions
and remeasuring are included as an adjustment to shareholders' equity. The
method of accounting for the effects of foreign currency transactions and of
remeasuring for our subsidiaries' financial condition and results of operations
will change in the event that the functional currencies for our subsidiaries
change. For example, due to our recent acquisitions of IMPSAT Corporation's
retail dial-up access customers in Argentina and Brazil and our pending
acquisition of its retail dial-up access customers in Colombia, the principal
source of revenues for several of our subsidiaries will be connectivity services
which will generally be priced and billed in local currency.

    We do not currently hedge against currency exchange transaction risks, but
could in the future engage in hedging activities against specific foreign
currency transaction risks. Because of uncertainties involving exchange rate
movements, we cannot quantify the effect of exchange rate movements on our
future financial condition or results of operations.

    In June 1998, the Financial Accounting Standards Board, which is commonly
called FASB, issued Statement of Financial Accounting Standards (SFAS) No. 133,
"Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133
establishes accounting and reporting standard for derivative instruments,
including derivative instruments embedded in other contracts, and for hedging
activities. In June 1999, FASB issued SFAS 137, "Accounting for Derivative
Instruments and Hedging Activities Deferral of Effective Date of FASB Statement
No. 133," which deferred the effective date of SFAS 133 to all fiscal quarters
of fiscal years beginning after June 15, 2000. We are currently evaluating the
effect that adoption of SFAS No. 133 will have on our financial statements.

                                    BUSINESS

OVERVIEW

    We are an Internet network providing country-specific and regional content
for Spanish- and Portuguese-speaking audiences in Latin America and the United
States. Recognizing that the countries in the Americas are diverse, we have
designed our network to consist of country Websites as well as a global Website.
We currently have country Websites for, and sales and content production offices
in, Argentina, Brazil, Mexico, the United States and Uruguay. We plan to
establish sales and content production offices in Colombia before the end of
1999, and sales and content production offices in Chile and Venezuela during
2000. By offering content and interactive resources designed to be responsive to
our users' preferences, we seek to make our network their "home on the Internet"
and, in so doing, to create communities of users, develop user loyalty and
increase traffic on our Websites. The launch of each country Website represents
a potential new community of users. By building substantial communities of
users, we are developing a platform for generating revenues from advertising,
branded retail dial-up Internet access, or "connectivity", service and, in the
future, e-commerce. We recently began to offer connectivity services in
Argentina and Brazil and expect to offer similar services in Colombia before the
end of 1999. We are also beginning to develop e-commerce for Spanish- and
Portuguese-speaking audiences in Latin America and the United States.

    Our founders believed that a scarcity of Spanish- and Portuguese-language
content was the principal factor limiting the growth of Internet usage in Latin
America. As a result, from our inception in mid-1997, we initially concentrated
on the development of a pilot Website for Argentina with quality content and
interactive resources in Spanish and, at the same time, carried out extensive
market testing to understand users' preferences. We then began to roll-out our
network of country Websites during 1998 and, most recently, launched our Website
in the United States in September 1999. Our registered users (meaning users who
have provided personal information such as name, e-mail address and address)
grew from 54,132 persons in June 1998 to 291,567 persons in July 1999. From
June 1998 to July 1999, the number of pages viewed by our users increased from
3.0 million to 21.0 million per month. On August 1, 1999, we launched our first
mass media-based branding and advertising campaign in Argentina, Brazil, Mexico
and Uruguay and, in September 1999, in the United States. In the first three
months of this campaign (through October 31, 1999), our registered users
increased by approximately 69% to approximately 498,515 at October 31, 1999 and
the number of pages viewed by our users increased by over 250% to approximately
73.9 million pages in that month. In March 1999, we also commenced measuring
unique visitors. The number of unique visitors has increased from 174,800 in
March 1999 to approximately 1.6 million in October 1999. We attribute this
recent growth principally to our mass media-based branding and advertising
campaign, and cannot predict whether such growth will continue.

OUR MARKET OPPORTUNITY

    The Spanish- and Portuguese-speaking audiences in Latin America and the
United States together represent one of the fastest growing user groups on the
Web today. While we do not expect to have country Websites or operations for
every country in Latin America, our network is targeted to the entire Latin
American region. In the United States, we are currently targeting the
Spanish-speaking populations in Chicago, Houston, Los Angeles, Miami, New York,
San Antonio and San Diego. We are primarily targeting individual users, although
we anticipate that business and other entities will become important
participants in our communities of users.

    We believe a large and growing market consisting of Spanish- and
Portuguese-speaking audiences exists in Latin America and the United States for
content, connectivity and e-commerce services, and that this market presents us
with a significant opportunity. Latin America had a total population at the end
of 1998 of 492.4 million people, of whom more than two thirds are under
35 years of age. The

                                       50
<PAGE>
region had an aggregate gross domestic product in 1998 of $2.0 trillion, of
which Brazil, Mexico and Argentina accounted for more than three-fourths. The
wealthiest 20% of the Latin American population accounts for approximately
two-thirds of the overall buying power in the region and constitutes our primary
target market. As a result, we believe that the Latin American market has a
highly desirable demographic profile for advertisers and businesses.

    Internet usage has only begun to penetrate Latin America, but its growth is
expected to be dramatic. Internet users in Latin America have grown from
approximately 2.3 million at year-end 1997 to 4.8 million at year-end 1998, and
are projected to increase to 19.1 million by year-end 2003, representing an
increase in Internet penetration of 0.6% to 3.7% (measured in relation to the
total population of the region). According to industry reports, the Internet
penetration rate in 1998 was 0.8% in Argentina, 1.1% in Brazil, 0.4% in
Colombia, 0.6% in Mexico and 1.9% in Chile.

    The United States has a total Hispanic population of approximately
31.4 million people, which has grown at a compound annual rate of 3.7% from 1996
to 1999. By 2000, the U.S. Hispanic population is expected to constitute
approximately 11% of the total U.S. population. Advertising targeting U.S.
Hispanics was $1.7 billion in 1998. As of May 1999, the Internet penetration
rate for U.S. Hispanics was approximately 19.0%.

    ADVERTISING.  Latin America represents an attractive market for advertisers.
Internet advertising in Latin America continues to grow as an advertising medium
because the Internet is being increasingly used by a desirable segment of the
Latin American population. Although Internet advertising is still in an
incipient stage in Latin America, it is expected to account for an increasing
share of total advertising expenditures in the region. Internet advertising in
Latin America totaled $23.6 million in 1998 and is projected to grow to
$948.9 million in 2003.

    CONNECTIVITY.  Connectivity services permit customers to access the Internet
through a local telephone call. At year-end 1998, there were approximately
3.0 million Internet subscriber accounts in Latin America, a number which is
projected to grow to 14.8 million by year-end 2003.

    Dial-up access charges have been declining in Latin America and at year-end
1998 averaged $31.48 per month. In addition to dial-up access charges, Internet
users are required to pay per minute telephone charges to connect to the
Internet. While per minute charges have not declined as rapidly as monthly
charges, we believe that they will trend downward as the effects of
telecommunications deregulation spread. Nonetheless, the all-in cost of dial-up
access remains significantly higher in Latin America than in the United States.
We believe that this cost has been a factor in limiting Internet penetration in
Latin America. However, the declining cost of dial-up access in Latin America is
a contributor to the projected growth of Internet use in Latin America.

    E-COMMERCE.  We believe that Latin America will, in the long-term, adopt
e-commerce as an increasing number of businesses and consumers embrace the
Internet as a viable method of selling and purchasing goods and services.
On-line expenditures in Latin America totaled $166.8 million in 1998 and are
expected to increase to $8.0 billion for 2003.

THE EL SITIO VISION

    Our founders envisioned an Internet network that would provide quality
country-specific content to Spanish- and Portuguese-speaking audiences in the
countries of Latin America, the United States and elsewhere. From our inception,
our philosophy has been to "Think regional, be local." Consistent with this
philosophy, we have opened offices in five countries in Latin America and in the
United States and have, to date, launched country Websites in each of these
countries. We believe that the combination of country Websites supported by
in-country management, marketing, sales and content production personnel will
enable us to implement the EL SITIO vision and to build the premier Internet
network for

                                       51
<PAGE>
Spanish- and Portuguese-speaking audiences in Latin America, the United States
and, over the long-term, Spain and Portugal.

    We believe our network should provide access for our users to a broad range
of Internet services as a means of further fostering our users' loyalty to our
network. Accordingly, we recently acquired the retail dial-up access customers
of IMPSAT Corporation in Argentina and Brazil, and expect to acquire its retail
dial-up access customers in Colombia by the end of 1999. We intend to utilize
our Websites as gateways to the Internet for subscribers to our connectivity
services. To further enhance the appeal of our network, we are also
incorporating a Web search engine into our network so that our users can utilize
our Websites as portals to search the Web.

    We believe our network provides a platform for generating revenues from the
following principal sources:

    - advertising;

    - connectivity services; and

    - e-commerce.

    To implement the EL SITIO vision, we have assembled a management team
experienced in building and operating pan-Latin American businesses. Our
management team is comprised largely of Latin Americans who provide us with
essential market knowledge and cultural insights. We believe that our local
presence allows us to better understand the needs of local Internet users,
advertisers and businesses, and to maintain strong relationships with them. Our
management team is drawn from diverse fields and includes professionals with
backgrounds in computer technology and design, sales, marketing and finance.

OUR STRATEGY

    Our goal is to become the leading Internet network for Spanish- and
Portuguese-speaking audiences in Latin America and the United States. To achieve
our goal, and to take advantage of our market opportunity, we continue to
implement a strategy consisting of the following principal elements:

  -   BUILDING A MARKET-LEADING NETWORK

    Our strategy is driven by our views, first, that the countries in Latin
America are diverse and, second, that the scarcity of Spanish- and
Portuguese-language content has been the principal factor limiting the growth of
Internet usage in Latin America. As a result, we seek to build a leading
Internet network by:

        V FURTHER DEVELOPING COUNTRY-SPECIFIC AND REGIONAL CONTENT. From our
          inception, we have focused on developing quality country-specific and
          regional Spanish- and Portuguese-language content. At September 30,
          1999, we had 67 employees dedicated to content development in the five
          countries in which we currently operate. During 2000, we expect to
          commence production of content for our planned country Websites for
          Chile, Colombia and Venezuela. We also provide content to our viewers
          under agreements with well-known content providers such as CBS
          Sportsline, Reuters and The Weather Channel. In addition, the
          community features on our Websites are designed to encourage our users
          to contribute content to our network. By continuously expanding and
          enhancing our production of proprietary and user-generated content,
          and, by entering into arrangements with leading third-party content
          providers we intend to maintain our position as a market leader in
          Spanish- and Portuguese-language content.

        V INCORPORATING ADDITIONAL COMMUNITY-BUILDING FEATURES. Our experience
          indicates a strong preference on the part of Latin American users for
          community-building features, such as chat,

                                       52
<PAGE>
          CUPIDO NET, e-mail and other interactive resources. Consistent with
          our user-focused business philosophy, prior to the roll-out of our
          network, we launched a pilot Website and engaged in an extensive
          period of market testing to identify the preferences of Internet users
          in each of our target markets. In response to those preferences, we
          have developed and continuously seek to enhance our content channels
          and interactive resources in order to further build our community of
          users and foster their loyalty to our network. One recent example is
          the launch of CUPIDO NET, an interactive meeting place for users,
          which at September 30, 1999, three months after its inception, had
          43,924 members. We continue to seek to better understand the needs and
          preferences of our users through on-line surveys and analysis of
          traffic patterns and usage of services.

        V STRENGTHENING OUR BRAND IDENTITY. After first dedicating our resources
          to develop our content and network, we launched our first mass
          media-based branding and advertising campaign on August 1, 1999. We
          expect to spend approximately $15.5 million through December 31, 1999
          and approximately $40.0 million in 2000 on this campaign. We seek to
          create the leading network brand among Spanish- and
          Portuguese-speaking Internet users and to expand our presence as a
          mass market Internet network by building strong brand awareness. We
          have positioned our image as user-friendly, informative and
          entertaining. We believe that the essence of our brand is summed up in
          our marketing campaign theme: EL SITIO: TU LUGAR EN INTERNET ("EL
          SITIO: Your Home on the Internet"). To build upon our brand, we plan
          to continue to advertise on the Internet to on-line users, and to
          allocate a significant portion of our resources to advertising,
          marketing and communications in traditional advertising media.

  -   GENERATING REVENUES FROM OUR NETWORK

    While our country-specific and regional content, community-building features
and brand identity are the building blocks to our becoming the premier Internet
network for Spanish- and Portuguese-speaking audiences, our revenue-generation
strategy is the key to our long-term success. We intend to capitalize on our
network to generate substantial revenues by:

        V FORGING ONE-ON-ONE RELATIONSHIPS WITH ADVERTISERS. The market for
          advertising on the Internet by Latin American companies is still in
          its infancy, with limited market awareness of the benefits of Internet
          advertising. As a result, an important part of our sales strategy is
          to forge one-on-one relationships with advertisers in which we educate
          companies regarding the full commercial advantages of the Internet as
          an advertising medium, emphasizing the attractive demographics of
          Latin American Internet users, and thereby attract advertisers to our
          network. With offices in each of our principal markets, at
          September 30, 1999, we had a total of 83 sales and marketing personnel
          dedicated to developing long-term relationships with potential
          advertisers and expanding our advertising revenues. Our structure
          permits us to develop relationships not only with multinationals
          purchasing advertising on all of our Websites, but also with
          country-specific advertisers interested in advertising targeted to
          users in their country. We are generating advertising revenue
          currently in Argentina, Brazil, Mexico, the United States and Uruguay.

        V INTEGRATING CONNECTIVITY INTO OUR NETWORK. In order to broaden the
          services that we offer and to foster user loyalty, we have acquired
          from IMPSAT Corporation its retail dial-up access customers in
          Argentina and Brazil and are in the process of acquiring its retail
          dial-up access customers Colombia. We believe that offering EL
          SITIO-branded connectivity services will increase user loyalty to our
          network. We intend to utilize our Websites as the gateways to the
          Internet for our subscribers. To further enhance the appeal of our
          network, we are incorporating a Web search engine into our network so
          that our users can utilize our Websites as portals to search the Web.
          By establishing a commercial relationship with our users, particularly
          through billing their monthly dial-up access fees to their credit
          cards, we expect

                                       53
<PAGE>
          that resistance to commercial purchases on our network will decline.
          We are currently generating subscription fee-based revenue in
          Argentina and Brazil from the provision of connectivity services.

        V DEVELOPING OUR E-COMMERCE BUSINESS. We believe our e-commerce
          opportunities will, over the long term, expand as an increasing number
          of Latin American businesses and consumers embrace the Internet as a
          viable method of purchasing goods and services, and we intend to
          capitalize on these opportunities. We recently added an e-shopping
          channel to our network. We also concluded a non-exclusive agreement
          with From2.com, a Miami-based e-commerce logistics company, which will
          provide logistics and fulfillment services for international
          e-commerce transactions conducted on our network. We are pursuing
          several revenue-sharing relationships and joint venture opportunities
          with e-commerce merchants in the United States and Latin America to
          develop e-commerce retail operations in the flower, gifts, books,
          music and software and hardware areas. We do not expect to derive
          meaningful revenues from e-commerce activities until at least 2001.

  -   LEVERAGING STRATEGIC RELATIONSHIPS

    We intend to leverage our existing relationships with shareholders and enter
into new strategic relationships to expand our network and enhance our content,
marketing and sales. In the months following our July 1999 private placement,
our key strategic shareholders, Hicks, Muse, Tate & Furst Incorporated, the
Cisneros Group of Companies and GC Companies Inc., have facilitated a variety of
new commercial relationships, including introduction to potential advertising
customers and e-commerce partners.

OUR NETWORK

    We are an Internet network providing country and regional content for
Spanish- and Portuguese-speaking audiences in Latin America and the United
States. Our network currently consists of a global Website and five
country-specific Websites focused upon Argentina, Brazil, Mexico, the United
States and Uruguay. We believe we are distinguished by our strong focus on
country-specific and regional content. We have grown our network by opening
local offices and hiring staff to develop content that is specific to the
countries in which we operate.

    We commenced operations in Argentina in mid-1997 and shortly thereafter
launched a pilot Website for that country. We opened our Montevideo office in
November 1997 and our Mexico City office in May 1998. After extensive market
testing and development of our content production capacity, we launched the
ELSITIO.COM network in November 1998 in Argentina, Mexico and Uruguay. We
currently have 148 employees in Buenos Aires, 58 in Mexico City and 16 in
Montevideo. We opened our office in Brazil in September 1998, launched the
Brazilian OSITE.COM.BR Website in the Portuguese language in July 1999 and now
have 35 employees in Sao Paulo. We opened our office in Miami in May 1998,
launched our U.S. Website in September 1999 and now have 28 employees in Miami.
We believe our local presence allows us to better understand the needs of local
advertisers and businesses. We plan to establish sales and content production
offices in Colombia before the end of 1999 and sales and content production
offices in Chile and Venezuela during 2000. We will hire a total of 53 employees
who previously worked for IMPSAT Corporation or its subsidiaries in connection
with our acquisitions of its retail dial-up access customers in Argentina,
Brazil and Colombia.

    Our offices and country-specific content afford our users the dual
advantages of, first, the size and resources of a regional network and, second,
the country-specific content and community features most useful to them.
Operationally, this structure permits us to maximize economies of scale to
support efficiently multiple markets with differing content and features from a
single global platform.

                                       54
<PAGE>
    Our global content and design team, in consultation with our country
offices, designs our homepage and community features, acquiring or developing
software required to offer the features that our market research indicates will
most appeal to our users. This global team also generates a large volume of
global content, both proprietary and from third-party providers such as Agence
France Presse, Reuters, CBS Sportsline and The Weather Channel. Technological,
financial and administrative functions are also carried out at the global level.

    The content and community features prepared by our global team provides the
starting point from which our in-country production teams adapt our global
Website to their local market preferences. Our local and regional production
offices in Buenos Aires, Mexico City, Miami, Montevideo and Sao Paulo cultivate
our users' preferences by adapting the content and community features on our
channels to local preferences. Local managers and their staff have autonomy to
select the stories and features that are headlined on our channels, to add
country-specific proprietary or third-party content and to add channels or
features with a local focus. For example, the editorial manager of EL SITIO
Mexico might select news items specific to Mexico or enhance a story without a
Mexican focus by including reactions in Mexico to the news item. Similarly, the
editorial manager of O SITE in Brazil might provide reviews of local restaurants
in Sao Paulo or Rio de Janeiro and might add, during February of each year, a
channel on CARNAVAL.

PRODUCT DESCRIPTION

    We have developed a network of country Websites that provide original
proprietary and third-party content and user-friendly interactive resources,
including free e-mail, auctions, chat rooms, personal home pages, bulletin
boards, contests and prizes, that bring our own style to our user base.

    Based on our market research activities, we believe there are four key areas
of interest that attract our targeted users: interactive news; relationships;
technology; and entertainment. These four areas of interest are reflected in our
core channels in each country Website.

    We believe that our core channels define the personality and vision of our
products. Our core channels currently are:

    - INTERACTIVE NEWS--Our staff transforms relevant daily news in each country
      into an interactive experience for our users. User interest is encouraged
      through presentation of the news in an entertaining style. News articles
      include debates, polls, forums and trivia, which allow our readers and
      editors to become part of the articles. In addition to our daily news, we
      have global and local third-party news coverage.

    - RELATIONSHIPS--We cover relationship topics that interest our users, such
      as love, family, friendship, society, sex, politics. We want our users to
      communicate and share important life experiences with our community of
      users. In addition to interactive responses that we generate from polls
      and forums, we typically receive over 500 narratives each day from our
      users from which we select some responses to display on our channels.

    - TECHNOLOGY--Our staff produces technology-related content with both the
      new and the experienced Internet user in mind. Tutorials, guides and news
      about technology and the Internet are provided to assist new users in
      learning how to navigate the Internet. We also cater to more experienced
      users through, among other things, sophisticated materials, software and
      application downloads and technology-related news. Our free technology
      newsletter, which now has over 100,000 subscribers, gives us an
      opportunity to interact with our users on a weekly basis.

    - ENTERTAINMENT--We provide our users with entertainment-related content in
      areas such as music, fashion, TV and movies. We also create an interactive
      environment for our users through interviews, polls and forums. For
      example, our users act as journalists and moderators during

                                       55
<PAGE>
      interviews with top models or TV stars. We also provide our users a
      variety of games, contests and prizes on a daily basis.

    In addition to our four core channels, we recently began to provide an
e-shopping channel:

    - E-SHOPPING--We anticipate that e-shopping opportunities will originate
      from our core channels. Once in the e-shopping channel, our users will
      encounter a user-friendly environment that helps them shop, provides them
      with merchant and product comparisons, and gives them shopping ideas.

    We also provide a series of general and country-specific channels. Our
general channels include:

    - NOTICIAS/NOTICIAS ("NEWS")--provides news sources by a variety of
      strategic partners. Third-party content is complemented by editorials,
      opinion articles and columns produced with local flavor by our journalists
      and staff members in Buenos Aires, Mexico City, Miami, Montevideo and Sao
      Paulo. Our strategic partners in News include Reuters, Agence France
      Presse, Notimex and Infosic.

    - COMUNIDAD/COMUNIDADE ("COMMUNITY")--encourages interaction of our users
      through a series of user-friendly resources that allow them to chat, voice
      their opinions and express their creativity through their own pages on the
      Internet.

    - SERVICIOS/SERVICOS ("SERVICES")--provides a local experience for our users
      through restaurant, hotel and movie recommendations, as well as local
      listings of theaters, museums and the arts in Buenos Aires, Mexico City,
      Miami, Montevideo and Sao Paulo. We expect to develop similar content for
      other major Latin American cities and our targeted cities in the United
      States that have large Spanish-speaking populations.

    - JUEGOS/JOGOS ("GAMES")--offers users a variety of multimedia, action,
      arcade and promotional games, in which users compete for prizes awarded by
      many of the companies advertising on our Websites. Our local writers
      contribute to the channel by providing editorials on Web games. Our users
      have the ability to download games directly from this channel.

    - DEPORTES/ESPORTES ("SPORTS")--provides up-to-date news, analysis,
      interviews and opinions on a broad range of sports. Through an arrangement
      with CBS Sportsline (which excludes Brazil), we receive English-language
      information, which our editorial staff then develops into Spanish-
      language articles, in exchange for Spanish-language articles (also
      displayed on our Website) about sports in Latin America. This year, users
      will able to watch live sports events utilizing our multimedia
      capabilities. Users will also be able to search a reference library with
      features, statistics and other information about sports personalities in
      Latin America.

    - PADRES/PAIS ("PARENTS")--gives information to our users on the subject of
      parenting. This channel is co-produced with a group of specialized
      psychologists who participate in editorial support and respond to the
      confidential mail of users.

    - NEGOCIOS/NEGOCIOS ("BUSINESS")--through a short-term agreement with Zona
      Financiera, a major Latin American producer of business and financial
      information, our users currently have access to the latest business news
      and services such as stock market quotations, exchange rates, interest
      rates, mortgage and car loan rates, and insurance rates. In addition to
      Zona Financiera, we have an agreement with Patagon.com, a leading business
      content site in the region, under which Patagon.com will pay us to be a
      non-exclusive provider of co-branded business content inside our Website
      after the Zona Financiera agreement ends in the first quarter of 2000.

    - EL TIEMPO/O TEMPO ("THE WEATHER")--offers our users comprehensive and
      up-to-the minute weather information, including weather conditions and
      forecasts for over 4,700 cities worldwide. The content is provided through
      an agreement with The Weather Channel.

                                       56
<PAGE>
    We also provide our users in each country with a list of country-specific
channels that are available on some of our country Websites, including the
following:

    - HOMETOWN (USA)--provides local news for each of our targeted cities with
      large Spanish-speaking populations in the United States. News articles are
      produced by our own writers for our targeted markets: Chicago; Houston;
      Los Angeles; Miami; New York; San Antonio; and San Diego.

    - BELEZA (BRAZIL)--is a channel devoted to men and women with interests in
      fashion and beauty topics. Users can find articles that deal with issues
      usually found in fashion magazines. This channel is created with
      interactivity in mind so users can share their ideas and experiences on
      these topics.

    - GEOSFERA (BRAZIL)--is devoted to extreme sports, including hiking,
      skydiving, trekking, mountain climbing and other rigorous outdoor sports.

    - GASTRONOMIA (URUGUAY)--provides news and forums regarding local and
      international cuisine. Users can read and share experiences and recipes
      and also learn about the latest developments in the gastronomical world.

    - ASTROWELS (MEXICO)--is a channel on astrology topics. It includes studies
      and analysis on birth, early childhood, karma, horoscopes and
      compatibility.

    - VIDA (USA)--consists of a compilation of proprietary articles that deal
      with day-to-day issues and concerns of Hispanic populations in the United
      States. This channel covers topics such as race and identity, sex and
      politics, health, art, literature, second generation issues, food and
      nutrition, and others.

    Our user-friendly interactive resources include:

    - CHAT--provides entry to a "virtual community" in which our users interact
      in real-time group or one-on-one discussions. Users may voice their
      opinions on a variety of topics, such as sports, politics, relationships
      and current events. Our users create special interest chat rooms and can
      also participate in moderated chat rooms. On average, each chat user stays
      in our chat rooms for approximately 20 minutes.

    - CUPIDO NET--is an interactive meeting place on our network where users can
      search for new friends or special relationships. Users from different
      backgrounds and experiences share their interests through CUPIDO NET. As
      of September 30, 1999, three months after its launch, CUPIDO NET has
      generated approximately 43,924 members.

    - E-MAIL--permits users to sign up for free e-mail services in Spanish,
      Portuguese and English through our recently signed agreement with USA.Net,
      a leading provider of e-mail and messaging services. As part of this
      alliance, users will benefit from enhanced customization tools that will
      offer them control over their e-mail account, including customization of
      their e-mail interface. Since access to e-mail requires user registration,
      e-mail is expected to be a significant source of registered users and user
      data in the future. As of September 30, 1999, which is three months after
      its launch, we have generated approximately 46,790 EL SITIO e-mail
      accounts and 8,860 O SITE e-mail accounts.

    - AUCTIONS--enables sellers in Latin America and the United States to post
      their products inside our channel and take advantage of our expanding user
      base. Buyers and sellers give us their personal information in order to
      register as users of our auctions channel. We act as a meeting place for
      sellers and bidders, while final transactions are executed outside the El
      Sitio network. We closely monitor the information from our sellers. Our
      company does not receive any fee for

                                       57
<PAGE>
      transactions, but benefits from increased traffic to our network and from
      advertising revenues generated from the channel.

    - BUSCADOR/BUSCADOR ("SEARCH")--is an internal search engine which enables
      users to search our library of over 90,000 pages. To further improve the
      functionality and appeal of our network, we recently reached an agreement
      with Inktomi, a leader in search technology with a library of over
      110 million sites, in which we use their search engine software and have
      access to their database. These search features will enable our users to
      utilize our network to surf the Web.

    - TU SITIO PERSONAL/SEU SITE PESSOAL ("PERSONAL HOME PAGE")--offers our
      users the ability to create their own content through their personalized
      home pages in Spanish and Portugese. We provide the proprietary tools that
      help our users create their own ideas on the Web in order to share their
      content with others. We believe that affinity between us and our users
      increases as they share their own experiences through our network.

    - BULLETIN BOARDS--offer our users the ability to post their own views and
      opinions on a variety of topics to be read by other users on our Websites.
      In that way, our users promote dialogue on relevant issues, topics or
      events of interest to other users on our network.

    - PREMIOS/PREMIOS ("CONTESTS")--uses contests as a marketing tool to attract
      visitors to our network. A recent campaign with nearly 12,000 registered
      users participating is "SUBETE AL TREN DE EL SITIO" ("Climb Aboard the EL
      SITIO Train") in which e-mail users provide us with the e-mail addresses
      of their friends who ride with them in their "trains," thereby increasing
      their chances of winning a trip to one of many destinations in Latin
      America.

    Our network of Websites is designed to be the home of our users on the
Internet. We are positioning ourselves as the friendly Internet network that
informs and entertains. As a result, we are able to develop communities of
interest, fostering user loyalty, increased usage and longer stays at our
Websites. In addition, the interactive resources on our Websites help us to
create communities of interest which are valuable to advertisers and e-commerce
merchants seeking to attract customers with specific interests.

OUR COMMUNITY

    We are developing a substantial community of users, based in large part on
the content and community features of our network.

    Users accessing our Websites are encouraged to register with us on either a
full or partial basis. Full registration requires users to provide us with the
user's name, e-mail address, home address, telephone number, occupation and
other personal information. A partial registration requires a user to provide
only a name and e-mail address. To encourage full registration, some of our
network's most popular features require prior registration, such as private chat
rooms, CUPIDO NET, our interactive meeting place, free e-mail and participation
in games and other promotions. Once a user is registered with our network, we
are able to communicate with the user by e-mail and otherwise seek to involve
the user in our community. Although historically we have been unable to track
the frequency with which a particular user accesses our Websites, we have
recently implemented technology that will permit us to measure more precisely
the activity levels of our registered users.

                                       58
<PAGE>
    We track our user traffic principally on the following basis:

    - REGISTERED USERS--measures the cumulative number of users that have
      registered with our network by providing information such as name, e-mail
      address and address. Some of these registered users may no longer be
      active users. Most of our users have not yet registered with our network.

    - PAGE VIEWS--measures the number of pages opened by our users in a given
      period and is a useful indicator for advertisers.

    - VISITS--measures the number of visits to our Websites in a given period.

    - UNIQUE VISITORS--measures the number of individual visitors in a given
      period, such that an individual user that visits our Websites multiple
      times in the relevant period is only counted one time.

    We have generated statistics concerning our registered users. Our page view
data is supplied by I/Pro Netline reports. Our unique visitor numbers are
audited by I/Pro. In November 1999, we retained ABC Interactive, which has
commenced auditing our traffic statistics.

    The table below sets forth, on a monthly basis over the last thirteen months
(September 1998 through October 1999) the evolution in our registered user base
and page views on a monthly basis:

</TABLE>

    We increased our registered user base from approximately 54,132 persons in
June 1998 to 291,567 in July 1999. From June 1998 to October 1999, the number of
pages viewed by our users increased from 3.0 million to 73.9 million per month.
We achieved a significant increase in registered users and user traffic in
January and February 1999, in part as a result of our purchase for $223,000 in
December 1998 from Mandic S.A. of its chat rooms in Brazil and their integration
into our network. In August 1999, our number of registered users and our user
traffic increased significantly. This latter increase was attributable, in part,
to the launching on August 1, 1999 of our first mass media-based branding and
advertising campaign. In the first three months of this campaign, our registered
users increased by approximately 69% to 498,515 at October 31, 1999 and the
number of pages viewed by our users increased by over 250% to 73.9 million in
the month of October 1999. We commenced

                                       59
<PAGE>
measuring unique visitors in March 1999. The number of unique visitors has
increased from 174,800 in March 1999 to approximately 1.6 million in
October 1999.

CONNECTIVITY

    In order to broaden the services that we offer and to foster user loyalty,
we recently acquired the retail dial-up access subscribers of IMPSAT Corporation
in Argentina and Brazil and are in the process of acquiring its retail dial-up
access subscribers in Colombia. The total purchase price for these acquisitions
will be $21.5 million. As a result of these acquisitions, we have acquired
approximately 52,000 dial-up subscribers in Brazil and 14,000 dial-up
subscribers in Argentina and expect to acquire approximately 7,000 dial-up
subscribers in Colombia, for an aggregate total of approximately 73,000
subscribers.

    We believe our connectivity services will enable us to develop an additional
source of revenue and to create closer ties with Internet users in Latin
America. We also anticipate that our dial-up access service will enhance the
content and e-commerce aspects of our business, because we should be able to
attract our dial-up subscribers to our Websites. We believe that increased use
of our Websites will increase advertisers' interest in placing advertisements
and sponsorships on our network and will encourage e-commerce merchants to
partner with us and drive our e-commerce revenues. For example, a substantial
majority of the dial-up subscribers that we expect to acquire from IMPSAT
Corporation currently are not registered users of our network. We intend to
market to these subscribers by, among other things, having our homepage appear
automatically when they connect to the Internet through our dial-up access
service.

    We have begun an evaluation process to determine the most effective method
of migrating the IMPSAT Corporation Websites, which are currently used as the
homepages for some of these subscribers, to our Websites. We expect to continue
using the existing IMPSAT Corporation Websites during a transition period of
approximately nine months. During this transition, we anticipate that we will
gradually integrate our brand name and features onto these Websites before
migrating these subscribers entirely to our network of Websites.

    We are not acquiring the telecommunications infrastructure, such as
points-of-presence, switches and backhaul capacity, required to provide retail
Internet dial-up access. The acquisitions will be limited to the subscribers and
staff required to provide retail dial-up access. We have entered into three-year
services agreements with subsidiaries of IMPSAT Corporation under which it will
provide to us the necessary telecommunications infrastructure for a fee per port
or "channel" made available to our customers for the transmission of data.

    We plan initially to outsource help desk operations and technical support
for our dial-up access businesses. This approach should enable us to minimize
our fixed costs and respond more flexibly to changes in demand.

MARKETING

    We depend upon advertising to develop our brand and to attract users to our
Websites and subscribers to our connectivity services. We believe that we have
already achieved significant brand name recognition and market share principally
due to positive word-of-mouth resulting from our country-specific content,
without conducting an aggressive marketing campaign in mass media. From our
inception in June 1997 until September 30, 1999, we spent an aggregate total of
approximately $8.0 million on marketing, sales and advertising (including
advertising received in barter transactions in exchange for advertising on our
network). By contrast, we expect to spend $15.5 million in the five months from
August 1, 1999 to year-end 1999. In the future, we expect our branding and
advertising expenses to represent the largest single component of our expenses
and have budgeted approximately $40 million for 2000.

                                       60
<PAGE>
    MARKETING EFFORTS UP TO AUGUST 1, 1999.  During our first two years of
operations, we focused our resources upon the development of quality content in
Spanish and Portuguese and attractive interactive resources for our network. Our
marketing was limited to low-budget initiatives, including:

    - targeted e-mail advertising;

    - banner advertising on the Web with hyperlinks to our Websites; and

    - special games and promotions on our Websites.

    Our advertising seeks to position us as the friendly Internet network that
informs and entertains with quality content, ease of use and responsiveness to
user preferences. Our marketing campaigns communicate these values using the
advertising logo with the tag line underneath: EL SITIO: TU LUGAR EN INTERNET
("EL SITIO: Your Home on the Internet"). These brand values, together with our
country-specific content and interactive resources, are designed to personalize
the on-line experience of our users, so that they may develop a one-to-one
relationship with us. We conduct direct marketing to our registered users
through e-mail campaigns.

    MARKETING EFFORTS SINCE AUGUST 1, 1999.  We launched our first mass
media-based branding and advertising campaign on August 1, 1999. Principally as
a result of this campaign, during the first three months of this campaign
(through October 31, 1999), we experienced an approximately 69% increase in
registered users and an over 250% increase in page views during those three
months. This campaign seeks to build our brand by creating brand recognition in
our target markets, attracting new users to our network and increasing our
exposure and visibility to potential advertisers. To achieve these objectives,
the campaign emphasizes the user friendly attributes of our network with the
theme that EL SITIO SE ADAPTA A VOS ("EL SITIO adapts to you"). The spots and
print media utilize humor to communicate the idea that EL SITIO is a network
that is responsive to its users and provides information and resources useful to
their daily lives.

    Our mass media-based branding and advertising campaign is under way in the
five countries for which we have launched country-specific Websites: Argentina,
Brazil, Mexico, Uruguay and the United States. Our campaign utilizes the
following media:

    - broadcast media, including both television and radio;

    - print media, including general circulation magazines, computer industry
      advertising and business magazines and general circulation newspapers;

    - on-line banner advertising with hyperlinks to our Websites;

    - targeted e-mail;

    - advertising and computer industry trade shows;

    - billboard and other outdoor advertising; and

    - general public relations to generate favorable free news media coverage.

The content and implementation of our branding and advertising campaign is being
coordinated by major advertising agencies in each of our markets under the
umbrella of WPP Group PLC. This campaign is targeting both potential users and
potential advertisers on our network.

    In September 1999, we entered into an agreement with Sammy Sosa, the
renowned baseball player, and Player's Choice International L.L.C. under which
we will have the exclusive right to utilize, modify, reproduce, distribute,
display and transmit Sammy Sosa's name in electronic form for use on the
Internet. Sammy Sosa has agreed to use his best efforts to increase awareness of
our Internet portals by wearing clothing and accessories bearing our logo on at
least four nationally televised events during the term of the agreement and by
attending three of our promotional events per year. Sammy Sosa has also agreed
to make himself available for at least one television show, one radio show and
one still photo advertisement, and for at least three chat sessions per year. As
consideration for entering into

                                       61
<PAGE>
the agreement, Sammy Sosa will receive a total of $1.0 million and 25,000 common
shares of our company, with an option to purchase on or before January 31, 2001
an additional 25,000 common shares at a 25% discount from the closing trading
price of the common shares on January 29, 2001. Additionally, Sammy Sosa and
Player's Choice International L.L.C. will receive a percentage of the
advertising revenues generated and actually received as a result of the
agreement. The initial amount of the discount will be remeasured, on a quarterly
basis, based on the fair value of the common shares at the time they are issued.

    Our marketing strategy seeks, among other things, to build advertising
relationships and generate revenues. Our sales force is focused on major
advertisers and advertising agencies. We believe that relationships with Latin
American advertising agencies are important because they influence advertising
buying decisions by companies in the region.

    In October 1999, we entered into a letter of intent to establish an
arrangement with J. Walter Thompson Argentina S.A., under which it will purchase
advertising from us on each of our country-specific Websites and on our global
Website. We will advertise J. Walter Thompson's products and services, using
banners, sponsorships and other techniques. J. Walter Thompson has agreed to
purchase $3 million of advertising at a 33 1/3% discount from our normal rates
charged for similar advertising. In addition, we have agreed to obtain
approximately $20 million of the advertising that we intend to purchase during
2000 in Argentina, Brazil, Chile, Colombia, Mexico, the United States and
Venezuela, using J. Walter Thompson as our advertising agency.

SALES

    We expect to generate sales from three different sources:

    - advertising;

    - connectivity; and

    - e-commerce.

    The following table sets forth, for the periods indicated, our net revenues
by country of operation (in thousands):

    ADVERTISING.  At September 30, 1999, we had an internal sales organization
of 30 professionals, who are based at our offices in Buenos Aires (10 persons),
Sao Paulo (6), Mexico City (6), Miami (6) and Montevideo (2). We plan to open
additional offices in Chile and Colombia during the fourth quarter of 1999 and
in Venezuela in 2000. A significant portion of our sales personnel's income is
commission-based. All of our sales personnel sell advertising exclusively for
us. We are also seeking representation agreements with advertising agencies for
the sale of advertisements on our Websites. Our sales personnel focus on both
selling advertisements on the Websites and developing long-term strategic
relationships with clients.

    We seek to attract corporate advertisers by educating and communicating with
them regarding the benefits of the Internet as a business tool. Advertising on
the Internet by Latin American companies is still in an early stage of
development. Many Latin American companies have not developed a Website or an
Internet strategy and need advice on how to implement such a strategy. We help
companies to develop and implement Internet strategies.

                                       62
<PAGE>
    Our relationship with Arcor S.A., the world's largest hard sweets producer,
exemplifies our approach with advertisers. In May 1997, we approached Arcor
regarding an advertising program on the Internet. The plan evolved into a
complete on-line campaign consisting of a tri-lingual Website, Web pages for its
products, games, promotions, and interactive press management and maintenance.
We have produced over 1,400 Web pages for Arcor and have an advertising contract
with Arcor for all of Latin America. Arcor advertisements have appeared on our
Websites in Argentina, Brazil and Mexico.

    We offer an assortment of advertising options to our clients, including the
following:

    - banner advertising;

    - sweepstakes and promotions;

    - button advertising and sponsorships;

    - content development;

    - contextual links to merchandise;

    - opt-in direct marketing/lead generation;

    - e-mail sponsorship programs;

    - pre- and post-campaign market research; and

    - celebrity event sponsorships.

    We offer our advertisers the option to display their advertisements on one
or more of our country Websites, or on a regional basis. Our advertisers also
have the flexibility to specify the channels on our network and the Website
pages on which they wish their messages to appear.

    Some of our advertising clients include:

    - MGM Networks Latin America;

    - Nortel Networks;

    - Lucent Technologies;

    - Wall Street Journal Interactive;

    - Arcor S.A.;

    - Intel Corporation;

    - Supermercados Norte;

    - Sun Microsystems; and

    - Banco de Galicia y Buenos Aires.

    We have derived a substantial majority of our revenues to date from the sale
of advertisements and sponsorships. In the nine months ended September 30, 1999,
we had 116 advertisers, representing an increase from 18 advertisers in the
corresponding period of 1998. In the nine months ended September 30, 1999, three
of our customers, Gastardelli, Perez y Gaudio Publicidad, an Argentine publicity
company, IMPSAT S.A. and Gramatur accounted for 7.8%, 7.9% and 6.3%,
respectively, of total revenues. In 1998, each of four advertisers, IMPSAT S.A.,
Arcor, S.A., Compaq Corporation and Antel (Uruguay), accounted for more than 10%
of our revenues. Gastardelli, Perez y Gaudio Publicidad acquired a large block
of advertising to resell to its advertising customers. We intend to pursue
similar relationships with other advertising agencies and brokers.

    Prior to November 1998, we sold advertising primarily at a fixed price per
month for a fixed banner. Currently, our markets are evolving and appear to be
developing along the lines of the U.S. Internet industry model, in which
advertising is sold on a cost-per-thousand impressions, or "CPM,"

                                       63
<PAGE>
basis. The cost of our advertising products varies according to the product. For
example, a banner with "click-through" or "hyper-link" capabilities is more
costly than a simple textual banner. Similarly, sponsorship of a channel or page
is more costly than acquiring a fixed number of CPMs. Our contracts with
advertisers and advertising agencies range from one to twelve months. Our
advertisers have tended to receive a guaranteed number of impressions for a
fixed fee. In the future, we expect that an increasing portion of our
advertising contracts will be long-term CPM-based contracts.

    We provide our advertisers with statistics related to the traffic on our
network provided by ABC Interactive. Receipt of audited statistics enables our
advertisers to assess more accurately the market penetration of their
advertising message. We believe our provision of audited statistics to
advertisers gives us a competitive advantage over networks which do not provide
such statistics to advertisers.

    CONNECTIVITY.  In light of our acquisitions of IMPSAT Corporation's retail
dial-up access customers in Argentina and Brazil and our pending acquisition of
its retail dial-up access customers in Colombia, we are integrating the sales
personnel in each country into our network's existing sales team. We expect to
gain economies of scale as we eliminate overlapping functions and integrate
sales strategies and resources. We are currently assessing our sales strategy
and personnel to determine the best way to integrate our connectivity services
into our mass media-based branding and advertising campaign. By initially
focusing on the connectivity services market in Argentina, Brazil and Colombia
more effectively than IMPSAT Corporation had done before, we hope to increase
our subscriber base. To that end, we expect to expand our sales activities
beyond telemarketing and word-of-mouth advertising to increase our visibility.

    We expect to price our connectivity services in response to market
conditions. We are also likely to launch new pricing initiatives in an effort to
increase the loyalty of subscribers to our network. Initially, we anticipate
maintaining the current sales and pricing strategies for our dial-up access
subscribers. Although we will vary pricing and sales strategies by country, the
connectivity businesses that we are acquiring offer a range of plans ranging
from unlimited access with e-mail accounts to e-mail access only plans. The
following illustrates the principal products, each of which includes an e-mail
account, offered at August 31, 1999 in Argentina and Brazil, our two principal
markets for connectivity services:

<TABLE>

<S>                                              <C>
- - unlimited access (with three e-mail            - unlimited access;
  accounts);

- - unlimited access;                              - 20 hours per month;

- - 15 hours per month;                            - ten hours per month;

- - six hours per month; and                       - one hour per month; and

- - e-mail access only.                            - e-mail access only.
</TABLE>

For Internet use above the pre-paid access levels, subscribers are charged
per-minute rates. In Argentina, at September 30, 1999, the prices for
connectivity services ranged from $45.00 per month (plus VAT) for unlimited
access with three e-mail accounts to $5.00 per month (plus VAT) for e-mail
access only. In Brazil, at September 30, 1999, the prices for connectivity
services ranged from approximately R$34.90 per month for unlimited access to
approximately R$4.95 per month for e-mail access only. The average monthly
subscription fee in Argentina in September 1999 was $24.80 per month, in Brazil
was $12.41 per month and in Colombia was $19.95 per month. The weighted average
subscription fee in September 1999 for the subscribers to be transferred in
Argentina, Brazil and Colombia was $15.74.

    E-COMMERCE.  We recently added an e-shopping channel to our network. This
channel provides a limited offering of books, flowers, music, gifts and
technology products which are made available from local and U.S.-based
e-merchants.

                                       64

CORPORATE ALLIANCES AND CONTENT AND APPLICATIONS PROVIDERS

    In order to increase traffic at our Websites, expand our on-line community
and build our brand, we continue to pursue strategic relationships with business
partners that offer quality content, technology and distribution capabilities as
well as marketing and cross-promotional opportunities.

    CONTENT.  We have an arrangement with CBS Sportsline, pursuant to which we
receive English-language information, which our editorial staff develops into
Spanish-language articles for us, in exchange for Spanish-language articles
(also displayed on our Website) about sports in Latin America. We have also
entered into agreements with leading content producers such as Reuters, Agence
France Presse, The Weather Channel, Notimex and Infosic, among others, under
which such companies provide content to us for publication on our network in
return for a fixed fee or revenue-sharing arrangement based on minimum page
views.

    CONNECTIVITY.  In connection with our acquisitions of retail dial-up access
customers of IMPSAT Corporation in Argentina and Brazil, and our pending
acquisition of its retail dial-up access customers in Colombia, we have not
acquired, and will not acquire, the telecommunications infrastructure to provide
these services. Instead, we will outsource that infrastructure from third-party
providers, initially, from IMPSAT Corporation. We have entered into three-year
services agreements with subsidiaries of IMPSAT Corporation in Argentina and
Brazil, according to which, in exchange for a fee per port or "channel" made
available to our customers for the transmission of data, IMPSAT will provide us
with the telecommunications infrastructure and equipment installation and
maintenance services to provide Internet dial-up access to our subscribers on a
24-hour, 365-day basis using equipment owned by subsidiaries of IMPSAT
Corporation. We currently estimate that the aggregate fee payable by us for
these services will be approximately $500,000 per month. The terms of the
service agreements will be automatically extended for another period of three
years unless prior notice is given by either party to the contrary. The service
agreements do not restrict IMPSAT Corporation from providing better rates to
other dial-up access providers. However, each service agreement provides for a
price adjustment if after the first year of the agreement, we receive an offer
from a third party on more favorable terms. If the subsidiary of IMPSAT
Corporation is unable to match or exceed the offer we receive from such
third-party competitor, we have the right to terminate the agreement, with no
penalties for early termination. Each service agreement also contains quality
standards provisions. We plan to enter into a substantially similar agreement in
Colombia by the end of the fourth quarter 1999.

    APPLICATIONS.  We have recently entered into several important agreements
relating to the provision of a variety of third-party licenses and other
applications. For example, we have entered into an agreement with Inktomi, a
leading Internet company, under which we will acquire the search engine software
and access to the database of Inktomi, a leader in search technology with a
library of over 110 million sites. We also recently concluded a letter of intent
with From2.com, a Miami-based e-commerce logistics company, for it to provide
logistics and fulfillment services for international e-commerce transactions
conducted on our network. Finally, through our recently signed agreement with
USA.Net, a leading provider of e-mail and messaging services, our users will
have access to free e-mail services in Spanish, Portuguese and English.

    E-COMMERCE.  We are pursuing several revenue-sharing relationships and joint
venture opportunities with e-commerce merchants in the United States and Latin
America to develop electronic retail operations in the flower, gifts, books,
music and hardware and software areas. We do not currently offer e-commerce
products or services and are in the process of developing strategic alliances
and relationships to provide e-commerce in the future. Our agreement with
From2.com will allow our users to calculate the actual cost of Internet
purchases from locations outside of their own country by calculating shipping,
handling, taxes and customs costs required to deliver the product.

    RECENT STRATEGIC INVESTORS.  On July 7, 1999, we completed a private
placement of our Class A convertible preferred shares to strategic investors,
including Hicks, Muse, Tate & Furst Incorporated and the Cisneros Group of
Companies (through their jointly owned IAMP (El Sitio) Investments, Ltd.), and
GCC Investments, LLC, an indirect subsidiary of GC Companies, Inc., which owns
and operates General Cinemas Theatres. In connection with our acquisitions of
retail dial-up customers from IMPSAT Corporation, IMPSAT Corporation will
purchase approximately $21.5 million of our Class A convertible preferred
shares. On August 31, 1999, we entered into an agreement with TV Azteca, S.A. de
C.V., pursuant to which we will receive $3.5 million of advertising time on TV
Azteca's television network in return for approximately $2.5 million of Class A
convertible preferred shares.

    In mid-November 1999, we completed a private placement of 1,111,111 Class B
convertible preferred shares for a purchase price of $10.0 million in cash, or
$9.00 per Class B convertible preferred share. Purchasers of the Class B
convertible preferred shares consisted of Intel Atlantic, Inc., a subsidiary of
Intel Corporation, and Latinvest Asset Management do Brasil, Ltda., an affiliate
of Globalvest Management Company, L.P. Each Class B convertible preferred share
will automatically convert, on the date six months after the closing date of
this offering, into one common share. The difference between the initial public
offering price per common share and $9.00 price per Class B convertible
preferred share will be amortized as a deemed dividend during the same six-month
period.

    We believe these strategic investors present us with opportunities to build
strategic relationships, expand brand awareness and grow our network. For
example, our relationship with Hicks, Muse Tate & Furst Incorporated and the
Cisneros Group of Companies is expected to give us access to media in Latin
America in which these shareholders have significant interests, and on which we
can promote our Websites and build brand awareness, including six radio stations
and one television station in Chile, and a number of pan-Latin American cable
television programming networks including Much Music and the Playboy Channel.
The Cisneros Group of Companies also controls Venevision, the number one
television network in Venezuela, and has an interest in Univision, a leading
Spanish-language television network in the United States. In Argentina, Hicks,
Muse also has interests in Canal 11 and Canal Azul, two television channels; in
Cablevision; and in numerous magazines and various sports programming networks.
GCC Investments, LLC is expected to assist us, among other things, in our
marketing efforts by contributing its extensive retail expertise to help us
develop our e-commerce opportunities. In addition, TV Azteca is the number two
television network in Mexico. We intend to work closely with our strategic
investors in order to take advantage of the synergies created by our
relationships. For example, we have commenced discussions with a number of
potential clients or joint venture partners as a result of contacts established
through our strategic investors.

TECHNOLOGY

    NETWORK OF WEBSITES.  We make our Websites available using 17 Microsoft
Windows NT servers and three Linux servers as our central production servers,
which are currently located at the server farm facilities of Exodus
Communications in New Jersey. We also have a back-up production server at IMPSAT
Corporation's server farm facilities in Miami, Florida. In each of Argentina,
Brazil, Mexico, Uruguay and the United States, we maintain a data center for
development and staging.

    We have implemented an environment in which each server can function
separately. Key components of our server architecture are served by multiple
redundant machines. As part of the Exodus server farm facilities, we have up to
100Mbps of bandwidth access over our Internet connections, which are fully
redundant so that if a failure in the network or equipment of one service
provider occurs, traffic is automatically routed through one of several other
providers. Each of Exodus Communications and IMPSAT Corporation provides
comprehensive facilities management services, including human and technical
monitoring of all production servers 24 hours per day, 7 days per week. All
facilities are protected by multiple power supplies. Our operations will depend
on the ability of IMPSAT Corporation and Exodus Communications to provide
adequate space, air-conditioning,

                                       66
<PAGE>
telecommunication connectivity and protection of their systems against damage
from fire, hurricanes, power loss, telecommunications failure, break-ins or
other events.

    We employ in-house and third-party monitoring software for our servers,
processes and network connectivity. Reporting and tracking systems generate
daily traffic, demographic and advertising reports. All of our production
systems are copied to backup tapes each night and regularly stored in a storage
facility on Exodus's premises as well as in a storage facility at our offices in
Buenos Aires. We have implemented these various redundancies and backup systems
in order to minimize the risk associated with damage from fire, power, loss,
telecommunications failure, break-ins, computer viruses and other events beyond
our control.

    Our network of Websites must accommodate a high volume of traffic and
deliver frequently updated information. Components or features of our network
have in the past suffered outages or experienced slower response times because
of equipment or software downtime. We are in the process of migrating our
platform and our applications to a Unix platform using Sun Microsystems servers,
which we believe will increase the reliability, availability and serviceability
of our network. We anticipate that this migration process, which we believe will
not affect the continuous operation of our network, will be completed by the end
of 1999.

    CONNECTIVITY.  In connection with our acquisitions of retail dial-up access
customers of IMPSAT Corporation in Argentina and Brazil, and our pending
acquisition of its retail dial-up access customers in Colombia, we have not
acquired and will not acquire the telecommunications infrastructure, such as
telecommunications bandwidth, points-of-presence, switches and backhaul
capacity, to provide these services. Instead, we will outsource that
infrastructure from third-party providers-- initially, from subsidiaries of
IMPSAT Corporation. We have entered into three-year services agreements with
subsidiaries of IMPSAT Corporation in Argentina and Brazil, according to which,
in exchange for a fee per port or "channel" made available to our customers for
the transmission of data, IMPSAT Corporation will provide us with the
telecommunications infrastructure and equipment installation and maintenance
services to provide connectivity services to our subscribers on a 24-hour,
365-day basis using equipment owned by subsidiaries of IMPSAT Corporation. We
currently estimate that the aggregate fee payable by us for these services will
be approximately $500,000 per month.

    IMPSAT Corporation uses routers with average connectivity speed of 33Kbps,
with a majority of subscribers migrating to a speed of 56Kbps. IMPSAT S.A.
(Argentina) subscribers are able to connect to the Internet through special
Internet dedicated phone lines at rates significantly cheaper than connecting
through conventional phone lines.

COMPETITION

    Many companies provide Websites, connectivity services and e-commerce
targeted to Spanish- and Portuguese-speaking audiences. All of these companies
compete with us for user traffic, advertising dollars and e-commerce
opportunities. The market for Internet content companies in Latin America is new
and rapidly evolving. Competition for users, advertisers and e-commerce
opportunities is intense and is expected to increase significantly in the future
because there are no substantial barriers to entry in our markets.

    We compete with providers of content and services over the Internet,
including Web directories, portals, search engines, content sites, Internet
service providers and sites maintained by government and educational
institutions.

    We face competition on both a country-specific and regional level. Our
primary competitors include, among others, StarMedia and Terra Networks (in most
of Latin America, the United States and the Iberian peninsula), Quepasa.com and
Yupi (in the United States), Clarin Digital (in Argentina) and Universo Online
(in Brazil). We also face competition from Spanish-and/or Portuguese-language

                                       67
<PAGE>
versions of U.S. services, such as Yahoo!, America Online and Prodigy
Communications. Our competitors may develop content that is better than ours or
that achieves greater market acceptance. It is also possible that new
competitors may emerge and acquire significant market share. Some of our
established competitors and potential new competitors may have better brand
recognition and significantly greater financial, technical and marketing
resources than our company.

    As a result of our completed and pending acquisitions of the retail dial-up
access customers in Argentina, Brazil and Colombia of IMPSAT Corporation, we
recently entered the dial-up access services market, which is extremely
competitive and is characterized by rapidly changing technology and evolving
standards. We do not own telecommunications infrastructure and, therefore, will
depend upon telecommunications providers to carry our Internet traffic.
Increased competition could require us to lower our prices, increase our selling
and marketing expenses, and raise subscriber acquisition costs. New technologies
permitting faster dial-up may make our connectivity services business obsolete.
We may not be able to retain our users or, if we do, to offset the effect of
increased costs through an increase in users, user revenues or revenues from
other sources.

    We expect to experience increased competition from the traditional
telecommunications carriers. We believe that there is a move toward horizontal
integration by these carriers through acquisitions of, joint ventures with, or
the wholesale purchase of connectivity from Internet service providers in order
to meet the Internet connectivity requirements of their business customers.

    We also compete with traditional forms of media, such as newspapers,
magazines, radio and televison, for advertisers and advertising revenue. If
advertisers perceive the Internet or our network to be a limited or an
ineffective advertising medium, they may be reluctant to devote a portion of
their advertising budget to Internet advertising or to advertising on our
network.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

    We consider our EL SITIO, O SITE and medallion design trademarks and service
marks to be important to our success. We are pursuing the registration of our
trademarks and service marks in the United States and in key countries of Latin
America as well as Spain and Portugal. Although some of the countries have
registered our marks, we cannot predict with certainty whether the trademarks
office of the remaining countries will do the same. If we are unable to obtain a
registration in a particular country, we would have trademark or service mark
rights to the extent that we use the mark, but the rights would not be as strong
as if they were registered. Some companies, including other participants in the
Internet industry, use and/or may use trademarks or service marks in English or
other languages which, when translated, are similar to certain of our core
marks. This usage may hinder our ability to build a unique brand identity and
may possibly lead to trademark disputes, in that we may be sued for trademark
infringement in court or we may have the validity of our applications and/or
registrations challenged at government agencies. Although we do not believe that
such proceedings against us ultimately would be meritorious, we cannot predict
that with certainty. Should we lose the right to use a trademark or service
mark, we may be forced to adopt a new mark which would result in the loss of
substantial resources and brand identity. In any event, whether successful or
not, litigating a trademark dispute would result in the expenditure of monetary
resources and the diversion of executives' time. Any inability to protect,
enforce or use our trademarks, service marks or other intellectual property may
have a material adverse effect on our company.

    We also depend upon technology licensed from third parties for chat,
homepage, search and related Web services. Any dispute with a licensor of the
technology may result in our inability to continue to use that particular
technology. Additionally, there may be patents issued or pending that are held
by third parties and that cover significant parts of the technology, products,
business methods or services used to conduct our business. We cannot be certain
that our technology, products, business methods or services do not or will not
infringe valid patents or other intellectual property rights held by

                                       68
<PAGE>
third parties. In the event that a third party alleges infringement, we may be
forced to take a license, which we may not be able to obtain on commercially
reasonable terms. We may also incur substantial expenses in defending our
company against third party infringement claims, regardless of the merit of
these claims. Successful infringement claims against us could result in
substantial monetary liability and/or being prevented by a court from conducting
all or a part of our business that falls within the scope of the asserted
patent, leading to substantial expenditures to redesign and/or license
technology.

GOVERNMENT REGULATION

    There are currently few laws or regulations directly applicable to access to
or commerce on the Internet. However, due to the increasing use of the Internet,
a number of legislative and regulatory proposals are under consideration by
various governments and governmental agencies or bodies.

    The following is a brief summary of the current regulatory framework for the
Internet industry in the countries in which we have or plan to have operations:

    - ARGENTINA. There are no laws or regulations governing on-line content
      providers in Argentina, but dial-up access providers, in general, must
      hold a correspondent license from the national telecommunications
      authority. We have applied for that license and expect to receive it in
      due course. The timing for completion of this application process is
      unclear, particularly given recent regulatory changes in Argentina.
      Dial-up access providers are also required to include a legend on their
      invoices to clients, stating that the national government does not control
      or regulate the information on the Internet and to provide contact
      information for help with blocking undesirable content.

    - BRAZIL. There are no laws or regulations governing on-line content
      providers or dial-up access providers in Brazil.

    - COLOMBIA. There are no laws or regulations governing on-line content
      providers. Telecommunications services are public services for which a
      value-added license must be obtained from the Colombian government. We are
      in the process of applying for that license and expect to receive it in
      due course. A dial-up access provider must be incorporated as a Colombian
      company, file an application with the national communications authority
      and meet specific technical and economic criteria. Finally, a dial-up
      access provider is required to pay a royalty for the license of 3% of the
      net annual income.

    - MEXICO. In Mexico, the federal telecommunications law requires that each
      provider of any value-added services (which includes Internet services)
      register with the telecommunications registry of its national
      telecommunications authority. This registration requires, among other
      things, disclosure of foreign investments, a list of transmission
      equipment, and a technical description of the services provided. In
      October 1999, our registration was declared effective by the COMISION
      FEDERAL DE TELECOMUNICACIONES (Mexican Federal Telecommunications
      Commission).

    - URUGUAY. There are no laws or regulations governing on-line content
      providers or dial-up access providers in Uruguay.

    - UNITED STATES. There are currently few U.S. laws or regulations which
      specifically regulate communications or commerce over the Internet.
      On-line content providers may be subject to lawsuits for information that
      they disseminate, such as lawsuits claiming defamation and infringement of
      copyrighted materials.

    It is possible that laws or regulations may be adopted or applied with
respect to the Internet relating to issues such as the following:

    - sales and other taxes;

                                       69
<PAGE>
    - user privacy;

    - pricing controls;

    - characteristics and quality of services and products;

    - consumer protection;

    - cross-border e-commerce;

    - libel and defamation;

    - copyright, trademark and patent infringement; and

    - other claims based on the nature and content of Internet materials.

    The adoption or application of any of these laws or regulations may
negatively affect the growth in the use of the Internet, which could, in turn,
decrease the demand for our services and products, increase our costs of doing
business, or otherwise have a material adverse effect on our company.

EMPLOYEES

    At September 30, 1999, we had 285 full-time employees, including 79 in
production and development, 83 in sales and marketing, 30 in technology and 93
in finance and administration. We believe that we have attracted an experienced
management team and a highly professional staff.

    We have hired 48 employees, who previously worked for IMPSAT Corporation or
its subsidiaries, following our acquisition of its retail dial-up access
customers in Argentina and Brazil. We expect to hire five additional employees
who previously worked for IMPSAT Corporation or its subsidiaries after
completion of our pending acquisition of IMPSAT's retail dial-up access
customers in Colombia.

FACILITIES

    Our headquarters are located in Buenos Aires, where we currently lease
approximately 1,300 square meters. We also are leasing additional premises for
our new corporate headquarters in that city, to which we anticipate moving in
before the end of 1999.

    We lease approximately 240 square meters in Sao Paulo, 265 square meters in
Mexico City, 80 square meters in Montevideo and 230 square meters in Miami.

LEGAL PROCEEDINGS

    There are no material legal proceedings pending or, to our knowledge,
threatened against us.

    - salaries and incentive compensation for our employees and consultants; and

    - the administration of our share option plans.

DIRECTOR COMPENSATION

    Directors currently do not receive stated compensation from our company for
their service as members of our board of directors. However, by resolution of
the board of directors, directors may receive a fixed amount and reimbursement
for expenses in connection with the attendance at board of directors and
committee meetings.

    Our directors did not receive any payments in connection with their services
as such in the year ended December 31, 1998.

    Under a shareholders' agreement entered into in connection with the
July 1999 private placement of our Class A convertible preferred shares,
monitoring and directors' fees of $700,000 per year, in the aggregate, are
payable to IAMP (El Sitio) Investments Ltd., GCC Investments, LLC, Tower Plus
International, SLI.com Inc., Militello Limited and IMPSAT Corporation.

    From time to time, some of our directors may be granted options to purchase
shares of common shares.

EXECUTIVE OFFICER COMPENSATION

    The aggregate amount of compensation paid by us to our executive officers
was $131,637 for the year ended December 31, 1998.

    We operate in an industry that is highly competitive in terms of
compensation to talented executive and technical staff. We believe that we have
been able to attract a group of experienced executives with proven track records
in their areas of expertise for our key management positions.

    Some of our executive officers have employment agreements with our company
for three-year terms. Each of these agreements provides for a specified monthly
salary, a minimum annual bonus and share options.

1999 SHARE OPTION PLAN

    We view share options as a key financial incentive to attract, motivate and
retain our talented employees. Accordingly, we have adopted our 1999 share
option plan which, as amended, provides for the issuance of up to 1,240,000
common shares. An additional 2,000,000 common shares were reserved on
October 28, 1999. Our 1999 share option plan allows for the grant of incentive
share options qualified within the meaning of Section 422 of the U.S. Internal
Revenue Code of 1986 and

                                       74
<PAGE>
non-qualified share options, which do not so qualify. Each option granted under
the plan shall be evidenced by an agreement that specifies the terms and
conditions of the grant. The plan also provides for the issuance of share
appreciation rights.

    Our 1999 share option plan is administered by the compensation committee of
our board of directors. Subject to the limitations in our 1999 share option
plan, the compensation committee has authority to determine to whom options may
be granted and the terms of such options, including the exercise price, the
number of shares subject to each option, the conditions for vesting, the
expiration date and the form of consideration payable upon exercise of options.
All of our directors, employees and bona-fide consultants and advisors are
eligible for non-qualified share option grants; however, incentive share options
may only be granted to our employees. No individual may be granted options
totaling more than 15% of the total number of options issuable under the plan.

    The exercise price of an incentive share option cannot be less than 100% of
the fair market value of a common share on the grant date, provided that no
person who owns, directly or indirectly, more than 10% of the total combined
voting power of all classes of our shares, referred to below as a "Ten-Percent
Shareholder," may receive incentive stock options unless the exercise price is
at least 110% of the fair market value of a common share on the grant date.
Options granted under the 1999 share option plan are not transferable by the
optionee, other than by will or by the laws of descent and distribution. All
options issued under the 1999 share option plan will have a term no longer than
10 years from the grant date, except that in the case of incentive stock options
granted to a Ten-Percent Shareholder, the term shall not exceed five years. The
1999 share option plan terminates on December 1, 2008 but such termination will
not affect the validity of any outstanding option.

    At September 30, 1999, options to purchase 1,238,400 common shares were
outstanding under the 1999 share option plan and 2,001,600 shares remained
available for future option grants. The weighted average exercise price for
these outstanding options is $3.01 per share. Most of these outstanding options
become exercisable either (i) in tranches (as to 30% of the options on the first
anniversary of the grant date, as to 30% of the options on the second
anniversary of the grant date and as to the remaining 40% of the options, on the
third anniversary of the grant date) or (ii) on the third anniversary of the
grant date. These options terminate upon the earliest to occur of the following:
termination of an optionee's employment for good cause, 30 days after an
optionee's resignation, 180 days after an optionee's employment is terminated
for any other reason, including retirement, disability or death, and eight years
after the grant date. Notwithstanding the foregoing, upon a change of control
(for example, a merger or similar transaction or the removal of a majority of
the members of our current board of directors) of our company that occurs on or
after the first anniversary of the grant date, all unvested portions of options
then outstanding will vest in full on that date.

    Our board of directors may amend, alter, suspend, or terminate the 1999
share option plan at any time, provided however, that the board must first seek
the approval of stockholders, if required by law or regulation, and that of each
affected optionee if such amendment, alteration, suspension or termination would
adversely affect his or her obligations under any option granted prior to that
date.

LIMITATION OF OFFICERS' AND DIRECTORS' LIABILITY

    Under British Virgin Islands law, every director and officer of our company,
in performing his or her functions, is required to act honestly and in good
faith with a view to the best interests of our company and exercise the care,
diligence and skill that a reasonably prudent person would exercise in
comparable circumstances. No provision in our memorandum or articles of
association or in any agreement entered into by us relieves a director or
officer from the duty to act in accordance with our memorandum and articles of
association or from any personal liability arising from his or her management of
the business and affairs of our company.

                                       75
<PAGE>
    We may indemnify any director or officer against all expenses, including
legal fees, and against all judgments, fines and amounts paid in settlement and
reasonably incurred in connection with legal, administrative or investigative
proceedings. We may only indemnify a director or officer if the director or
officer acted honestly and in good faith with the view to the best interests of
our company and, in the case of criminal proceedings, the director or officer
had no reasonable cause to believe that his or her conduct was unlawful. The
decision of the board of directors as to whether the director or officer acted
honestly and in good faith with a view to the best interests of our company and
as to whether the director or officer had no reasonable cause to believe that
his or her conduct was unlawful, is in the absence of fraud sufficient for the
purposes of indemnification, unless a question of law is involved. The
termination of any proceedings by any judgment, order, settlement, conviction or
the entry of NO PLEA does not, by itself, create a presumption that a director
or officer did not act honestly and in good faith and with a view to the best
interests of our company or that the director or officer had reasonable cause to
believe that his or her conduct was unlawful. If a director or officer to be
indemnified has been successful in defense of any proceedings referred to above,
the director or officer is entitled to be indemnified against all expenses,
including legal fees, and against all judgments, fines and amounts paid in
settlement and reasonably incurred by the director or officer in connection with
the proceedings.

    We may purchase and maintain insurance in relation to any director or
officer against any liability asserted against the director or officer and
incurred by the director or officer in that capacity, whether or not we have or
would have had the power to indemnify the director or officer against the
liability as provided in our articles of association.

                           RELATED PARTY TRANSACTIONS

    IMPSAT Corporation is controlled largely by the Pescarmona group, of which
Sofia Pescarmona, one of our directors, is a member. The Pescarmona group
indirectly owns approximately 75% of the capital stock of IMPSAT Corporation.
Roberto Vivo-Chaneton, our co-founder and chairman, is a director and deputy
chief executive officer of IMPSAT Corporation. Mr. Vivo beneficially owns
approximately 6% of the capital stock of IMPSAT Corporation. Ricardo Verdaguer,
another of our directors, is the president and chief executive officer of IMPSAT
Corporation. Mr. Verdaguer owns approximately 3.5% of the capital stock of
IMPSAT Corporation. We have acquired the retail dial-up access customers of
IMPSAT Corporation in Argentina and Brazil and are in the process of acquiring
its retail dial-up access customers in Colombia. We will acquire a portfolio of
approximately 73,000 customers of these businesses in the three countries. In
connection with the acquisitions, IMPSAT Corporation will purchase a total of
3,070,615 Class A convertible preferred shares for approximately $21.5 million,
and we will enter into agreements with subsidiaries of IMPSAT Corporation, under
which they will provide us with the telecommunications infrastructure to provide
connectivity services to the acquired customers for approximately $500,000 per
month. Under services agreements with subsidiaries of IMPSAT Corporation, IMPSAT
Corporation provides us with links to the Internet in exchange for advertising
on our network. This arrangement accounted for $38,000, $165,000 and $123,000 of
our net revenues and corresponding amounts of our operating expenses in partial
year 1997, 1998 and the nine months ended September 30, 1999, respectively.

    Guillermo Liberman is a director of Sociedad Latinoamericana de Inversiones,
the holding company of Grupo Liberman, which is involved in agribusiness,
fisheries, telecommunications and hotel development. An affiliate of Grupo
Liberman, Video Cable Comunicacion, or VCC, is a cable television system
operator which was sold to Tele-Communications, Inc. in 1997 in a series of
transactions for over $1 billion. Prior to the sale of VCC to
Tele-Communications, Inc., we entered into a reciprocal advertising agreement
with VCC pursuant to which each company provided the other with advertising
time. We previously leased offices from Grupo Liberman in Miami. Mr. Liberman
also is affiliated with one of our advertisers, TeleLatina, a start-up regional
telecommunications company in Latin America. TeleLatina accounted for
approximately $68,000 of our advertising revenues for the nine months ended
September 30, 1999.

    In July 1998, we acquired 85% of the Class A shares and 100% of the Class B
shares of Cibrian-Campoy Creativos, S.A., in Argentina, from its shareholders,
who included the following directors and executive officers: Roberto
Cibrian-Campoy; Guillermo Liberman and Roberto Vivo-Chaneton. We paid $50,000
for 85% of the common shares, and issued 3,432,094 of our common shares for 100%
of the preferred shares, of Cibrian-Campoy Creativos, S.A. In October 1997, we
purchased, for an aggregate purchase price of $1,700, the majority of the shares
of Aalefranger, S.A., in Uruguay, from its shareholders, who included Roberto
Vivo-Chaneton and Roberto Cibrian-Campoy. These two companies are the
predecessors of our operating subsidiaries in Argentina and Uruguay.

    Some of our directors have from time to time guaranteed short-term
indebtedness or other liabilities of our company. Mr. Vivo and Mr. Verdaguer
personally guaranteed payment of the monthly rent for our current headquarters
in Buenos Aires ($84,000 per year), as well as the rental of our new
headquarters at Azopardo in Buenos Aires ($228,000 per year).

    On July 7, 1999, we completed a private placement of 5,447,088 Class A
convertible preferred shares for a gross purchase price of $38.4 million in
cash. Strategic investors included Hicks, Muse, Tate & Furst Incorporated and
the Cisneros Group of Companies (through IAMP (El Sitio) Investments Ltd.) and
GC Companies, Inc. (through GCC Investments, LLC). As a part of the private
placement, we entered into an agreement with Washburn Enterprises, an affiliate
of the Cisneros Television Group, under which we also agreed to purchase at
least $4.0 million of advertising time on the media networks owed by Washburn's
affiliate Ibero-American Media Partners II Ltd. and its

                                       80
<PAGE>
affiliates, and Washburn agreed that it and its affiliates would purchase at
least $2 million of advertising time on our network, all during the period
through January 2001.

    Under a shareholders' agreement entered into in conjunction with the
July 1999 private placement, we pay monitoring fees and director fees of
$700,000 per year, in the aggregate, to IAMP (El Sitio) Investments Ltd., GCC
Investments, LLC, Tower Plus International, SLI.com, Inc., Militello Limited and
IMPSAT Corporation.

                        SHARES ELIGIBLE FOR FUTURE SALE

    Sales of our common shares in the public market could adversely affect
market prices for our common shares. Because no shares will be available for
sale shortly after this offering due to the contractual and legal restrictions
on resale described below, sales of substantial numbers of our common shares
after these restrictions lapse could adversely affect market prices and our
ability to raise equity capital in the future.

    Immediately upon completion of this offering, we will have outstanding an
aggregate of 38,574,460 common shares, assuming no exercise of the underwriters'
over-allotment option and no exercise of outstanding options or warrants. Of
these shares, all of the common shares sold in this offering will be freely
tradable without restriction or further registration under the Securities Act,
unless such common shares are purchased by "affiliates" as that term is defined
in Rule 144 under the Securities Act. Of the remaining common shares,
approximately 19,000,000 shares held by existing shareholders or issuable upon
conversion of our Class B convertible preferred shares will be "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 Rule 144 or 701 under the
Securities Act, which rules are summarized below.

LOCK-UP AGREEMENTS

    All of our directors and executive officers, some of our employees, and some
of our existing shareholders have entered into lock-up agreements under which
they agreed not to transfer or dispose of, directly or indirectly, any common
shares, subject to limited exceptions, or any securities convertible into or
exercisable or exchangeable for common shares, for a period of 180 days after
the date of this prospectus. Transfers or dispositions can be made prior to the
end of that 180-day period with the prior written consent of Credit Suisse First
Boston Corporation or in other limited circumstances. Subject to the provisions
of Rules 144, 144(k) and 701, a significant portion of the restricted shares
will be available for sale in the public market, subject in the case of shares
held by affiliates to compliance with certain volume restrictions, shortly after
the end of that 180-day period.

RULE 144

    In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned common shares
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 common shares then outstanding, which will equal
      approximately 385,745 shares immediately after this offering; or

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

    Sales under Rule 144 are also subject to certain manner of sale provisions
and notice requirements and to the availability of current public information
about us.

RULE 144(K)

    Under Rule 144(k), a person who is not one of our affiliates at any time
during the three months preceding a sale, and who has beneficially owned the
shares proposed to be sold for at least two years, including the holding period
of any prior owner other than an affiliate, is entitled to sell such shares
without complying with the manner of sale, public information, volume limitation
or notice provisions of Rule 144.

RULE 701

    In general, under Rule 701 of the Securities Act as currently in effect,
each of our employees, consultants or advisors who purchased common shares from
us in connection with a compensatory share plan or other written agreement is
eligible to resell such shares 90 days after the closing of this offering in
reliance on Rule 144, but without compliance with certain restrictions,
including the holding period, contained in Rule 144.

REGULATION S

REGISTRATION RIGHTS

    Upon completion of this offering, the holders of approximately 19,000,000
common shares, or their transferees, will be entitled to exercise rights to
cause us to register those shares for resale under the Securities Act of 1933.
These holders have these registration rights under the provisions of a
registration rights agreement that was entered into in connection with the
private placement of our Class A convertible preferred shares in July 1999.

1999 SHARE OPTION PLAN

    Immediately after this offering, we intend to file a registration statement
under the Securities Act covering 3,240,000 common shares reserved for issuance
under our 1999 share option plan. This registration statement is expected to be

    At September 30, 1999, options to purchase 1,238,400 shares were issued and
outstanding under our 1999 option plan. All of these shares will be eligible for
sale in the public market from time to time, subject to vesting provisions,
Rule 144 volume limitations applicable to our affiliates and, in the case of
some of the options, the expiration of lock-up agreements.

                          DESCRIPTION OF SHARE CAPITAL

GENERAL

    Our authorized capital consists of 200,000,000 common shares and 100,000,000
preferred shares, with 40,000,000 preferred shares designated as Class A
convertible preferred shares and 1,888,889 preferred shares designated as
Class B convertible preferred shares.

COMMON SHARES

    As of September 30, 1999, we had 12,568,098 common shares issued and
outstanding. All outstanding shares of common shares are fully paid and
non-assessable.

    The holders of common shares are entitled to one vote for each share held of
record on all matters submitted to a vote of our shareholders. Cumulative voting
is not permitted.

    Subject to the prior rights of any series of shares that may be issued in
the future, holders of common shares are entitled to receive, ratably, such
dividends as may be declared by our board of directors from funds legally
available therefor and are entitled to share, ratably, in all our assets
available for distribution to holders of common shares upon the liquidation,
dissolution or winding up of our affairs.

PREFERRED SHARES

    Authorized preferred shares may be issued from time to time by our board of
directors, in one or more series. Subject to the provisions of our articles of
association and the limitations prescribed by law, our board of directors is
authorized to adopt resolutions to issue the authorized preferred shares, to fix
the number of shares and to change the number of shares constituting any series,
and to provide for or change the voting powers, designations, preferences and
relative, participating, optional or other special rights, qualifications,
limitations or restrictions thereof, including dividend rights (including
whether dividends are cumulative), dividend rates, terms of redemption
(including sinking fund provisions), redemption prices, conversion rights and
liquidation preferences of the preferred shares of any class or series, in each
case without any further action or vote by the shareholders.

    One of the effects of undesignated preferred shares may be to enable our
board of directors to render more difficult or to discourage an attempt to
obtain control of our company by means of a tender offer, proxy contest, merger
or otherwise, and thereby to protect continuity of our management. The issuance
of preferred shares may adversely affect the rights of the holders of common
shares. For example, our preferred shares may rank prior to the common shares as
to dividend rights, liquidation preference or both, may have full or limited
voting, rights and may be convertible into common shares. Accordingly, the
issuance of preferred shares may discourage bids for the common shares at a
premium or may otherwise adversely affect the market price of the common shares.

CLASS A CONVERTIBLE PREFERRED SHARES

    GENERAL.  As of September 30, 1999, we had 5,832,566 Class A convertible
preferred shares outstanding. Upon the closing of this offering, each
outstanding Class A convertible preferred share will be automatically converted
into two common shares.

    DIVIDENDS.  The holders of the Class A convertible preferred shares are
entitled to receive cumulative preferential dividends at an annual rate equal to
8% of the liquidation preference per Class A convertible preferred share,
payable quarterly, in arrears.

    CONVERSION.  The holders of Class A convertible preferred shares may, at
their option, convert these shares into common shares at any time in whole or in
part. These Class A convertible preferred shares will be automatically converted
into common shares upon the closing of this offering.

                                       84
<PAGE>

right to vote, together with the holders of all the issued and outstanding
common shares and not by classes, except as otherwise required by British Virgin
Islands law, on all matters on which holders of common shares are entitled to
vote. In addition, we may not take certain corporate actions without the
affirmative vote or consent of the holders of a majority of the Class A
convertible preferred shares.

    Each holder of the Class A convertible preferred shares has the right to
cast one vote for each whole common share which would be issued to such holder
upon conversion of such holder's shares of Class A convertible preferred shares,
assuming that such conversion were to occur on the date immediately prior to the
record date for the determination of shareholders entitled to vote.

    LIQUIDATION, DISSOLUTION OR WINDING UP.  Upon any liquidation, dissolution
or winding up of our company, holders of Class A convertible preferred shares
are entitled to be paid an amount equal to the liquidation preference per
preferred share out of our assets before any distribution is made to any holders
of common or other junior shares.

    REGISTRATION RIGHTS.  In connection with the private placement in July 1999
of Class A convertible preferred shares, we entered into a registration rights
agreement with some of our shareholders. Under the registration rights
agreement, these shareholders have specified rights after a qualified offering
to cause us to register their holdings of common shares of $15.0 million or more
under the Securities Act of 1933. We have requested, and expect, that these
shareholders will waive their registration rights in connection with this
offering. We will also seek a waiver from these shareholders of the minimum
dollar per share feature of the qualified offering definition contained in the
registration rights agreement. We are required to bear all registration expenses
other than underwriting discounts and commissions and fees related to any
exercise of these registration rights. In addition, we have agreed to indemnify
the registration rights recipients against, and provide contribution with
respect to, liabilities under the Securities Act of 1933 in connection with
registrations.

CLASS B CONVERTIBLE PREFERRED SHARES

    GENERAL.  As of the date of this prospectus, we have 1,111,111 Class B
convertible preferred shares outstanding.

    DIVIDENDS.  The holders of the Class B convertible preferred shares are
entitled to receive cumulative preferential dividends at an annual rate equal to
8% of the liquidation preference per Class B convertible preferred share,
payable quarterly, in arrears.

    CONVERSION.  Each Class B convertible preferred share will automatically
convert, on the date six months following the closing date of this offering into
one common share, subject to specified anti-dilution adjustments. If this
offering is not consummated, the holders of Class B convertible preferred shares
may, after a period of six months, at their option, convert these shares into
common shares at any time in whole or in part.

    REDEMPTION.  The Class B convertible preferred shares are subject to
mandatory redemption beginning in July 2004, at a price equal to 100% of the
liquidation preference thereof, plus any and all accrued and unpaid cumulative

right to vote, together with the holders of all the issued and outstanding
common shares and not by classes, except as

                                       85
<PAGE>
otherwise required by British Virgin Islands law, on all matters on which
holders of common shares are entitled to vote.

    Each holder of the Class B convertible preferred shares has the right to
cast one vote for each whole common share which would be issued to such holder
upon conversion of such holder's shares of Class B convertible preferred shares,
assuming that such conversion were to occur on the date immediately prior to the
record date for the determination of shareholders entitled to vote.

    LIQUIDATION, DISSOLUTION OR WINDING UP.  Upon any liquidation, dissolution
or winding up of our company, holders of Class B convertible preferred shares
are entitled to be paid an amount equal to the liquidation preference per
preferred share out of our assets before any distribution is made to any holders
of common or other junior shares.

    REGISTRATION RIGHTS.  In connection with the private placement of Class B
convertible preferred shares, we entered into a registration rights agreement
with those investors. Under the registration rights agreement, the investors
have specified rights after this offering to cause us to register their holdings
of common shares of $5.0 million or more under the Securities Act of 1933. Each
Class B convertible preferred share will be convertible into one common share,
subject to specified anti-dilution adjustments. We will be required to bear all
registration expenses other than underwriting discounts and commissions and fees
related to any exercise of these registration rights. In addition, we have
agreed to indemnify the registration rights recipients against, and provide
contribution with respect to, liabilities under the Securities Act of 1933 in

                                    TAXATION

BRITISH VIRGIN ISLANDS TAX CONSIDERATIONS

    We are exempt from all provisions of the Income Tax Act of the British
Virgin Islands with respect to all dividends, interests, rents, royalties,
compensation and other amounts payable by our company to persons who are not
persons resident in the British Virgin Islands. Persons who are not persons
resident in the British Virgin Islands are also exempt from any capital gains
realized with respect to any shares, debt obligations or other securities,
including the common shares, of our company. No estate, inheritance, succession
or gift tax, rate, duty, levy or other charge is payable by persons who are not
persons resident in the British Virgin Islands with respect to any shares, debt
obligations or other securities, including the common shares, of our company.
There is no reciprocal tax treaty in force between the British Virgin Islands
and the United States.

U.S. FEDERAL INCOME TAXATION CONSIDERATIONS

    The following discussion describes the material U.S. federal income tax
considerations that may be relevant to a prospective purchaser of shares to a
U.S. Holder (as defined below) of the receipt of distributions on, and the
disposition of, our common shares. This discussion is based on provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), on the regulations
promulgated thereunder and on published administrative rulings and judicial
decisions, all as of the date hereof. We cannot assure you that future
legislation, administrative rulings or court decisions will not modify the
conclusions set forth in this summary, possibly with retroactive effect. The
discussion is of a general nature only and prospective purchasers of our common
shares are advised to consult their own tax advisors with respect to U.S.
federal, state and local tax consequences and tax consequences in other
jurisdictions, of the ownership of shares applicable in their particular
situation. Except as specifically set forth herein, this discussion deals only
with common shares held by a U.S. Holder as capital assets within the meaning of
Section 1221 of the Code, and does not address tax considerations applicable to
holders that may be subject to special tax rules, such as banks, insurance
companies, dealers in securities or currencies, tax-exempt entities, persons
that will hold shares as a position in a "straddle" or as part of a "hedging" or
"conversion" transaction for tax purposes or persons that have a "functional
currency" (as defined in Section 985 of the Code) other than the U.S. dollar.

    As used herein, a "U.S. person" is:

    - a United States citizen or resident;

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

    - an estate the income of which is subject to United States federal income
      taxation regardless of its source; or

    - a trust which is subject to the supervision of a court within the United
      States and the control of a United States person as described in
      section 7701(a)(30) of the Code or that has a valid election in effect
      under applicable U.S. Treasury regulations to be treated as a United
      States person.

A "U.S. Holder" is a beneficial owner of common shares that is a U.S. person. A
"non-U.S. Holder" is a beneficial owner of common shares that is not a U.S.
Holder.

    U.S. HOLDERS

    DIVIDENDS.  To the extent that a distribution on our common shares is paid
to a U.S. Holder out of our current or accumulated earnings and profits (as
determined for U.S. federal income tax purposes), that distribution will be
included in the U.S. Holder's gross income as foreign source dividend income

                                       87
<PAGE>
in an amount equal to the U.S. dollar value of the distribution (without
reduction for any applicable foreign withholding tax). Therefore, in the event
that any foreign tax is withheld from a distribution on the common shares, a
U.S. Holder generally will be required to report gross income in an amount
greater than the cash received (although, as discussed below, that U.S. Holder
may be eligible to claim a deduction or a foreign tax credit in respect of such
foreign tax). To the extent that the amount of any distribution on the common
shares exceeds our current and accumulated earnings and profits (as determined
for U.S. federal income tax purposes), a U.S. Holder's pro rata share of the
excess amount would be treated first as a nontaxable return of capital that
would be applied against and would reduce the U.S. Holder's tax basis in its
common shares (but not below zero), and then as capital gain. Distributions in
excess of our current and accumulated earnings and profits (as determined for
U.S. federal income tax purposes) generally will not give rise to foreign source
income and a U.S. Holder may be unable to claim a foreign tax credit in respect
of any British Virgin Islands or other foreign withholding tax imposed on those
distributions unless, subject to applicable limitations, the U.S. Holder has
other foreign source income in the appropriate category for foreign tax credit
purposes. We believe that we do not have current or accumulated earnings and
profits for U.S. federal income tax purposes. However, we cannot predict whether
we will have any such earnings and profits for future taxable years.

    Subject to certain conditions and limitations (including certain minimum
holding period requirements), the U.S. dollar value of the foreign income taxes,
if any, withheld from a distribution to a U.S. Holder on the common shares may
generally be claimed as a credit against the U.S. Holder's U.S. federal income
tax liability. Alternatively, a U.S. Holder may generally claim a deduction for
such amount of foreign income taxes withheld in a taxable year, but only if such
U.S. Holder does not elect to claim a foreign tax credit in respect of any
foreign taxes paid by it in the taxable year. Dividends on common shares
generally will constitute "passive income" or, in the case of some U.S. Holders,
"financial services income" for U.S. foreign tax credit purposes. Special rules
apply to some individuals whose foreign source income during the taxable year
consists entirely of "qualified passive income" and whose creditable foreign
taxes paid or accrued during the taxable year do not exceed $300 ($600 in the
case of a joint return).

    The rules relating to foreign tax credits are extremely complex and the
availability of a foreign tax credit depends on numerous factors. Prospective
purchasers of our common shares should consult their own tax advisors concerning
the application of the U.S. foreign tax credit rules to their particular
situations.

    The U.S. dollar value of any distribution to a U.S. Holder on shares that is
paid in a foreign currency will be calculated by reference to the exchange rate
in effect at the time the distribution is received by the U.S. Holder. If a U.S.
Holder that receives foreign currency from a distribution and does not convert
the foreign currency into U.S. dollars upon receipt, the U.S. Holder will
generally have foreign exchange gain or loss based on any appreciation or
depreciation of the value of the foreign currency against the U.S. dollar, which
will generally be U.S. source ordinary income or loss for U.S. foreign tax
credit purposes.

    A corporate U.S. Holder will not be entitled to a dividends-received
deduction with respect to distributions on our common shares.

    SALE OR EXCHANGE OF COMMON SHARES. A U.S. Holder generally will recognize
taxable gain or loss on any sale or exchange of a common share in an amount
equal to the difference between the amount realized for that common share and
the U.S. Holder's adjusted tax basis in that share. The gain or loss should be
capital gain or loss. Capital gains of individuals derived with respect to
capital assets held for more than one year are eligible for reduced rates of
taxation. The deductibility of capital losses is subject to limitations. Any
gain or loss recognized by a U.S. Holder will generally be treated as United
States source gain or loss for foreign tax credit purposes. As a result of
certain limitations under the

                                       88
<PAGE>
foreign tax credit provisions of the Code, a U.S. Holder may be unable to claim
a foreign tax credit for British Virgin Islands withholding taxes, if any,
imposed on the proceeds received upon the sale, exchange, repurchase by us or
other disposition of common shares.

    PASSIVE FOREIGN INVESTMENT COMPANY PROVISIONS. A foreign corporation will be
classified as a passive foreign investment company (a "PFIC") for U.S. federal
income tax purposes if 75% or more of its gross income for the taxable year is
passive income or on average for the taxable year, 50% or more of its assets, by
value (or, if it so elects, by adjusted basis), produce or are held for the
production of passive income. For this purpose, passive income generally
includes dividends, interest, royalties, rents (other than rents and royalties)
derived in the active conduce of a trade or business and not derived from a
related person), annuities and gains from assets that produce passive income. If
a foreign corporation owns at least 25% by value of the stock of another
corporation, the foreign corporation is treated for purposes of the PFIC tests
as owning its proportionate share of the assets of the other corporation and as
receiving directly its proportionate share of the other corporation's income. If
a foreign corporation is classified as a PFIC, in any year with respect to which
a U.S. Holder owns common shares, it generally will continue to be treated as a
PFIC, with respect to such shareholder in all succeeding years. We will notify
U.S. Holders by letter and provide them with the information as may be required
to make a "qualified electing fund" election effective.

    Based upon our current and projected income, assets and activities, we do
not expect that our common shares will be considered shares of a PFIC for our
current fiscal year or for future years. This conclusion is a factual
determination made annually and thus is subject to change. In reaching the
conclusion that we do not believe that our company is a PFIC, we have valued our
company's assets based on the price per share of the common shares. For purposes
of applying the PFIC rules to our company, this valuation method results in
substantial value being given to intangible assets, including goodwill, that are
considered neither to produce nor to be held for the production of passive
income for purposes of the PFIC rules. The U.S. Internal Revenue Service (the
"IRS") has neither approved or disapproved of this valuation method, although we
believe that it constitutes a reasonable method of valuing our company's
non-passive assets. In addition, we believe that our passive income, as defined
under Section 1297 of the Code, does not, and should not, equal or exceed 75% of
our gross income. We will notify U.S. Holders if our company becomes a PFIC in
any taxable year. We will notify U.S. Holders by letter and provide them with
the information required to make a "QEF election," as described below.

    If our company were treated as a PFIC, unless U.S. Holders make a "QEF
election" or a "mark-to-market election," each as described below:

    - distributions made by our company during a taxable year with respect to
      the common shares that are "excess distributions" (defined generally as
      the excess of the amount received with respect to the shares in any
      taxable year over 125% of the average received in the shorter of either
      the three previous years or your holding period before the taxable year)
      must be allocated ratably to each day of your holding period. The amounts
      allocated to the current taxable year and to taxable years prior to the
      first year in which our company was classified as a PFIC will be included
      as ordinary income in gross income for that year. The amount allocated to
      each other prior taxable year will be taxed as ordinary income at the
      highest rate in effect for the U.S. Holder in that prior year and the tax
      is subject to an interest charge at the rate applicable to deficiencies in
      income taxes; and

    - the entire amount of any gain realized upon the sale or other disposition
      of common shares will be treated as an excess distribution made in the
      year of sale or other disposition and as a consequence will be treated as
      ordinary income and to the extent allocated to years prior to the year of
      sale or disposition, will be subject to the interest charge described
      above.

                                       89
<PAGE>
    These special PFIC tax rules will not apply if the U.S. Holder elects to
have our company treated as a "qualified electing fund" (a "QEF election") and
our company provides certain information required for the QEF election. If our
company is treated as a PFIC, we intend to notify U.S. Holders and provide them
with that information as may be required to make the QEF election effective.

    If a U.S. Holder makes a QEF election, the U.S. Holder will be currently
taxable on its pro rata share of our company's ordinary earnings and net capital
gain (at ordinary income and capital gains rates, respectively) for each taxable
year of our company, regardless of whether or not distributions were received.
The U.S. Holder's basis in the common shares will be increased to reflect taxed
but undistributed income. Distributions of income that had previously been taxed
will result in a corresponding reduction in basis in the common shares and will
not be taxed again as a distribution.

    Alternatively, if the common shares are treated as "marketable stock," a
U.S. Holder may make a mark-to-market election. If this election is made, the
U.S. Holder will not be subject to the PFIC rules described above. Instead, the
U.S. Holder generally will include in each year as ordinary income the excess,
if any, of the fair market value of the common shares at the end of the taxable
year over the U.S. Holder's adjusted basis in the shares and will be permitted
an ordinary loss in respect of the excess, if any, of the U.S. Holder's adjusted
basis in the common shares over its fair market value at the end of the taxable
year (but only to the extent of the net amount previously included in income as
a result of the mark-to-market election). Basis in the shares would be adjusted
to reflect any such income of loss amounts. The mark-to-market election is only
available with respect to stock traded on certain U.S. exchanges and other
exchanges designated by the U.S. Treasury. It is anticipated that such election
would be available to U.S. Holders.

    U.S. Holders that own common shares during any year that our company is a
PFIC, must file IRS Form 8621. U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX
ADVISERS CONCERNING THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF HOLDING SHARES
OF OUR COMPANY IF IT IS CONSIDERED A PFIC.

    CONTROLLED FOREIGN CORPORATIONS.  If United States Shareholders in the
aggregate own more than 50% of the voting power or value of the shares of a
foreign corporation, it will be classified as a "controlled foreign corporation"
("CFC"). A "United States Shareholder" is any United States person that owns
(directly or through certain deemed ownership rules) at least 10% of the total
combined voting power of all classes of shares of a foreign corporation.

    If a foreign corporation is a CFC for an uninterrupted period of 30 days or
more during the taxable year, the United States Shareholders of the CFC will
generally be subject to current U.S. tax on certain types of income of the
foreign corporation ("Subpart F income," which includes dividends, interest,
certain rents and royalties, gain from the sale of property producing such
income and certain income from sales and services) and, in certain
circumstances, on earnings of the CFC that are invested in U.S. property,
whether or not cash is distributed by the CFC. In addition, gain on the sale of
the CFC's shares by a United States Shareholder (during the period that the
corporation is a CFC and thereafter for a five-year period) will be ordinary
income in whole or in part.

    If we are treated as a CFC, any U.S. Holder that acquires (directly or
through certain deemed ownership rules) 10% or more of the total combined voting
power of all classes of our shares will be required to include certain amounts
with respect to its investment in income currently. Our status as a CFC should
have no adverse effect on any U.S. Holder that is not a United States
Shareholder.

    FOREIGN PERSONAL HOLDING COMPANIES.  If five or fewer U.S. individuals own,
or are treated as owning under certain attribution rules, in the aggregate more
than 50% of the voting power or value of the shares of a foreign corporation,
and at least 60% (50% in certain circumstances) of the "gross income" of such
foreign corporation is made up of certain passive type income (for example,
dividends, interest, certain rents and royalties and gain from the sale of stock
or securities) for a taxable year, then such corporation will be a "foreign
personal holding company" ("FPHC"). If a foreign

                                       90
<PAGE>
corporation is a FPHC, U.S. persons that own shares in the FPHC (regardless of
the size of their shareholding and regardless of whether they are individuals)
will generally be subject to current U.S. tax on a pro-rata portion of the
FPHC's undistributed foreign personal holding company income ("FPHCI") for the
taxable year or part thereof, although tax-exempt U.S. investors will not be
subject to tax on amounts attributable to FPHCI. In addition, U.S. persons that
are required under these rules to include undistributed taxable income for a
taxable year and that own at least 5% of the value of the FPHC's shares are
required to comply with certain reporting requirements under Code. In addition,
if our company became a FPHC, U.S. persons who acquire their shares from
decedents would not receive a "stepped-up" basis in such shares. Instead, such
U.S. persons would have a tax basis equal to the lower of fair market value or
the decedent's basis.

    Based upon our current and projected income, assets and activities, we do
not expect the common shares to be considered shares of FPHC for our current
year or for future years. We will notify U.S. Holders if we become a FPHC in any
taxable year.

NON-U.S. HOLDERS

    A non-U.S. Holder generally will not be subject to U.S. federal income tax
on dividends paid by us with respect to the common shares unless such income is
effectively connected with the conduct by the non-U.S. Holder of a trade or
business in the United States.

    A non-U.S. Holder generally will not be subject to United States federal
income tax on any gain recognized on the sale or other disposition of the common
shares unless that gain is effectively connected with the conduct by the
non-U.S. Holder of a trade or business within the United States, or, in the case
of gains recognized by individual non-U.S. Holders, the individual is present in
the United States for 183 days or more and certain other conditions are met.

    Effectively connected dividends and gains of a non-U.S. Holder generally
will be subject to tax in the same manner as a U.S. Holder. These dividends and
gains realized by a corporate non-U.S. Holder may also, under certain
circumstances, be subject to an additional "branch profits tax" at a 30% rate or
such lower rate as may be specified by an applicable income tax treaty.

INFORMATION REPORTING AND BACKUP WITHHOLDING

    In general, information reporting requirements will apply to dividends in
respect of the common shares or the proceeds received on the sale, exchange or
redemption of common shares paid within the U.S. (and in certain cases, outside
the United States) to U.S. Holders other than certain exempt recipients, such as
corporations, and a 31% backup withholding may apply to such amounts if the U.S.
Holder fails to provide an accurate taxpayer identification number or to report
interest and dividends required to be shown on its U.S. federal income tax
returns. The amount of any backup withholding from a payment to a U.S. Holder
will be allowed as credit against the U.S. Holder's U.S. federal income tax
liability.

    Non-U.S. Holders are generally exempt from the information reporting and
backup withholding rules but may be required to comply with certification and
identification requirements in order to prove their exemption.

    The rules for information reporting and backup withholding requirements have
been altered in certain respects with respect to payments after December 31,
2000. It is possible that we and other withholding agents may request a new
withholding certificate in order to qualify for continued exemption from backup
withholding under Treasury regulations when they become effective. Holders of
the common shares should consult their tax advisers concerning the possible
application of these alterations to any payments made with respect to the common
shares.

</TABLE>

    The underwriting agreement provides that, the underwriters are obligated to
purchase and pay for all of the above common shares if any are purchased, other
than those common shares covered by the over-allotment option described below.
The underwriting agreement provides that, if an underwriter defaults, the
purchase commitments on non-defaulting underwriters may, in some circumstances,
be increased or the offering of common shares may be terminated.

    The underwriters propose to offer the common shares initially at the public
offering price set forth on the cover page of this prospectus and at this price
less a concession not in excess of $    per common share to other dealers who
are members of the National Association of Securities Dealers, Inc. The
underwriters may allow, and dealers may reallow, concessions not in excess of
$    per common share to other dealers. After the offering, the offering price,
concessions and other selling terms may be changed by the underwriters.

    We have granted an over-allotment option to the underwriters to purchase an
amount, up to an aggregate of 1,230,000 additional common shares, exercisable at
the initial public offering price less the underwriting discounts and
commissions, each as set forth on the cover page of this prospectus. If the
underwriters exercise this option in whole or in part, then each of the
underwriters will become obligated, subject to customary conditions, to purchase
approximately the same percentage of these additional common shares as is
approximately the percentage of common shares that it is obligated to purchase
of the total number of common shares under the underwriting agreement as shown
in the table set forth above.

    The following table summarizes the underwriting discount and estimated
expenses that we will pay:

    The underwriters have informed us that they do not expect discretionary
sales to exceed 5% of the shares of common shares being offered.

    The underwriting agreement provides that we will indemnify the underwriters
against liabilities under the Securities Act or contribute to payments that the
underwriters may be required to make in respect thereof.

    Our directors and executive officers and some of our existing shareholders
who collectively hold a total of 27,121,294 shares have agreed under lock-up
agreements not to sell or offer to sell or otherwise

                                       92
<PAGE>
dispose of any common shares, subject to limited exceptions, for a period
180 days after the date of this prospectus without the prior written consent of
Credit Suisse First Boston Corporation.

    Prior to the offering, there has been no public market for our common
shares. Consequently, the initial offering price for the common shares offered
hereby was determined by negotiations between us and the representative of the
underwriters. Among the factors considered in these negotiations were our
results of operations in recent periods, estimates of our prospects and the
industry in which we compete, an assessment of our management, the general state
of the securities markets at the time of the offering and the prices of similar
securities of generally comparable companies. We will apply to list our common
shares on the Nasdaq National Market under the symbol "LCTO." We cannot assure
you, however, that an active or orderly trading market will develop for the
common shares or that our common shares will trade in the public markets
subsequent to the offering at or above the initial offering price.

    In order to facilitate the offering, persons participating in the offering
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common shares during and after the offering. Specifically, the
underwriters may over-allot or otherwise create a short position in the common
shares for their own account by selling more common shares than we have actually
sold to them. The underwriters may elect to cover any short position by
purchasing common shares in the open market or by exercising the over-allotment
option granted to the underwriters. In addition, the underwriters may stabilize
or maintain the price of the common shares by bidding for or purchasing common
shares in the open market and may impose penalty bids, under which selling
concessions allowed to syndicate members or other broker-dealers participating
in the offering are reclaimed if common shares previously distributed in the
offering are repurchased in connection with stabilization transactions or
otherwise. The effect of these transactions may be to stabilize or maintain the
market price at a level above that which might otherwise prevail in the open
market. The imposition of a penalty bid may also affect the price of the common
shares to the extent that it discourages resales thereof. No representation is
made as to the magnitude or effect of these activities.

    The underwriters have reserved for sale, at the initial public offering
price, up to 820,000 common shares for directors, officers, employees, directors
and other persons associated with us who have expressed an interest in
purchasing common shares in the offering. The number of common shares available
for sale to the general public in the offering will be reduced to the extent
these persons purchase reserved common shares. Any reserved common shares not
purchased by these persons will be offered by the underwriters to the general
public on the same terms as the other common shares offered in this offering.
Some of the employees and other persons who will be offered reserved common
shares will be required to agree not to sell or offer to sell or otherwise
dispose of any common shares, subject to limited exceptions, for a period of 90
days after the date of this prospectus without the prior written consent of
Credit Suisse First Boston Corporation and Lehman Brothers Inc.

    A prospectus in electronic format is being made available on an Internet
Website maintained by Wit Capital Corporation, which is one of the underwriters
in this offering. In addition, all dealers purchasing common shares from Wit
Capital Corporation in this offering have agreed to make a prospectus in
electronic format available on a Website maintained by each of them. Other than
the prospectus in electronic format, the information on the Website and any
information contained on any other Website maintained by Wit Capital Corporation
or any dealer purchasing common shares from it is not part of this prospectus or
the registration statement of which this prospectus forms a part, has not been
approved and/or endorsed by us or any underwriter in its capacity as underwriter
and should not be relied on by prospective investors.

    Fidelity Capital Markets, a division of National Financial Services
Corporation, which is one of the underwriters in this offering, will be
facilitating electronic distribution of information through the Internet,
Intranet and other proprietary electronic technology.

                          INDEPENDENT AUDITORS' REPORT

To the Shareholders of El Sitio, Inc.:

    We have audited the accompanying consolidated balance sheets of El
Sitio, Inc. and its subsidiaries (the "Company") as of December 31, 1997,
December 31, 1998 and September 30, 1999, and the related consolidated
statements of operations and comprehensive loss, shareholders' equity (deficit)
and cash flows for the period from July 16, 1997 (date of inception) through
December 31, 1997, the year ended December 31, 1998, and the nine months ended
September 30, 1999. 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. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

    In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of the Company at December 31,
1997, December 31, 1998 and September 30, 1999, and the results of its
operations and its cash flows for the period from July 16, 1997 (date of
inception) through December 31, 1997, the year ended December 31, 1998, and the
nine months ended September 30, 1999 in conformity with generally accepted
accounting principles.

        (IN THOUSANDS OF U.S. DOLLARS, EXCEPT SHARE AND PER SHARE DATA)

1. BACKGROUND AND EVOLUTION

    El Sitio, Inc., a British Virgin Islands holding company (the "Company"), is
an Internet network providing country-specific and regional content, for
Spanish- and Portuguese-speaking audiences in Latin America and the United
States. The Company recently began to offer connectivity services in Argentina
and Brazil and expects to offer similar services in Colombia before the end of
1999. The Company intends to provide e-commerce services for Spanish- and
Portuguese- speaking audiences in Latin America and the United States.

    The Company was formed in July 1997 under the name Blasin International
Corporation. In October 1997 and July 1998, the Company acquired ownership of
interests in subsidiaries located in Uruguay and Argentina, respectively, which
were under common ownership. These acquired entities had been established in
Argentina and Uruguay on December 30, 1996 and February 24, 1997, respectively,
under the names of Cibrian Campoy Creativos S.A. ("El Sitio Argentina") and
Aalefranger S.A., an inactive entity ("El Sitio Uruguay"). During 1998,
operating subsidiaries have been established in Mexico ("El Sitio Mexico"), the
United States ("El Sitio USA") and Brazil ("El Sitio Brazil"). At September 30,
1999, the Company's operating subsidiaries were as follows:

</TABLE>

    The Company's successful completion of its development program and,
ultimately, the attainment of profitable operations is dependent on future
events, including maintaining adequate financing to fulfill its development
activities and achieving a level of income adequate to support the Company's
cost structure. With the proceeds of the private placement in July 1999 and from
anticipated future offerings, the Company will fund its sales and marketing, and
branding and advertising activities, expand its sales force, improve its network
infrastructure, develop new services and products, make strategic investments or
acquisitions and fund other corporate purposes.

2. MERGERS AND ACQUISITIONS

    In October 1997, the Company acquired 75% of the common shares of El Sitio
Uruguay, an inactive entity, for $1.7 in cash. This acquisition was accounted
for under the purchase method of accounting.

    In July 1998, the Company acquired 85% of the Class A shares of El Sitio
Argentina for $50 and 100% of the Class B shares of El Sitio Argentina in
exchange for the issuance of 3,432,094 common shares of the Company. This
acquisition, as is generally the case for transactions among companies under
common control, has been accounted for in a manner similar to the pooling of
interests method of accounting, whereby all assets and liabilities have been
recorded at their historical carrying amounts.

2. MERGERS AND ACQUISITIONS (CONTINUED)

    During the nine months ended September 30, 1999, the Company acquired the
remaining minority interest in El Sitio Argentina and El Sitio Uruguay. These
acquisitions were accounted for under the purchase method of accounting.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    BASIS OF PRESENTATION--The financial statements are presented on a
consolidated basis and include the accounts of the Company and its subsidiaries.
All significant intercompany transactions and balances have been eliminated.

    INTERIM FINANCIAL INFORMATION--The unaudited consolidated statements for the
nine months ended September 30, 1998 have been prepared on the same basis as the
audited consolidated financial statements. In the opinion of management, such
unaudited consolidated financial statements include all adjustments (consisting
only of normal recurring adjustments) necessary to present fairly the results
for such period. The results of operations for the nine month periods ended
September 30, 1998 and 1999 are not necessarily indicative of the results of
operations to be expected for the full fiscal year or for any future period.

    USE OF ESTIMATES--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
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.

    CASH AND CASH EQUIVALENTS--Cash and cash equivalents are highly liquid
investments, including short-term investments and time deposits with maturities
of three months or less at the time of purchase. Cash equivalents and short-term
investments are stated at cost, which approximates market value.

    REVENUE RECOGNITION--The Company's revenues are derived principally from the
sale of advertisements. The Company sells advertising primarily at a fixed price
per month. Revenues on these contracts are recognized ratably over the period of
time in which the advertisement is displayed. The Company also sells advertising
on a cost-per-thousand impressions, or "CPM" basis under which such advertisers
and advertising agencies receive a guaranteed number of "impressions,"or number
of times that an advertisement appears in pages viewed by users of the Company's
online properties, for a fixed fee. The Company's contracts with advertisers and
advertising agencies for these types of contracts cover periods ranging from one
month to one year. Advertising revenues are recognized ratably based on the
number of impressions displayed, provided that the Company has no obligations
remaining at the end of a period and collection of the resulting receivable is
probable. Company obligations typically include guarantees of minimum number of
impressions. To the extent that minimum guaranteed impressions are not met, the
Company defers recognition of the corresponding revenues until the remaining
guaranteed impression levels are achieved. Payments received from advertisers
prior to displaying their advertisements on the Company's network are recorded
as deferred revenues. Revenues from exclusive sponsorship arrangements are
recognized ratably. Additional revenue is generated from Website design and Web
hosting. Website design revenues are recognized once the related activities are

performed and the customer's website is complete and operational. Web hosting
revenues are recognized ratably over the term of the contracts.

    For the period ended December 31, 1997 and the year ended December 31, 1998,
the Company had five customers which each exceeded 10% of total revenue and
collectively represented 89% of revenues, and four customers which each exceeded
10% of total revenue and collectively represented 72% of revenues, respectively.
Three of the customers are common in both years. For the nine months ended
September 30, 1999, the Company had one customer which exceeded 10% of total
revenue and represented 13% of revenues.

    The Company in the ordinary course of business enters into reciprocal
services arrangements whereby the Company provides advertising service to third
parties in exchange for telecommunications services and advertising services in
other media. Revenues and expenses from these agreements are recorded at the
fair value of services provided or received, whichever is more determinable in
the circumstances. The fair value represents market prices negotiated on an
arms' length basis. Revenue from reciprocal services arrangements is recognized
as income when advertisements are delivered on the Company's Websites. Expense
from reciprocal services arrangements is recognized when telecommunication
services are received or the Company's advertisements are run in other media
which are typically in the same period when the reciprocal service revenue is
recognized. Related expenses which include telecommunication charges are
classified as product, content and technology and advertising charges are
classified as marketing and sales in the accompanying statements of operations.
During the period ended December 31, 1997 and the year ended December 31, 1998,
revenues attributable to reciprocal services totaled approximately $38 and $180,
respectively. For the nine months ended September 30, 1999, revenues
attributable to reciprocal services totaled approximately $554. No gain or loss
was recognized on these reciprocal services arrangements for the period ended
December 31, 1997, the year ended December 31, 1998 and for the nine months
ended September 30, 1999.

    PROPERTY AND EQUIPMENT--Property and equipment are recorded at cost and
depreciated using the straight-line method over the following estimated useful
lives:

Furniture, fixtures and other fixed assets..............  5 - 10 years
Vehicles................................................  5 years
Leasehold improvements..................................  5 years (lease term)
</TABLE>

    DEFERRED OFFERING COSTS--As of September 30, 1999, the Company had incurred
approximately $94 of transaction expenses relating to the initial public
offering which were included in prepaid expenses. Upon the successful closing of
the initial public offering, these costs will be netted against the proceeds of
the offering as part of additional paid-in-capital.

    LICENSES AND PERMITS--Licenses and permits are being amortized on a
straight-line basis over periods not exceeding two years.

    ADVERTISING EXPENSES--The Company expenses advertising costs as incurred.
Advertising expense was $17, $180 and $5,800 for the period ended December 31,
1997, the year ended December 31, 1998 and the nine months ended September 30,
1999, respectively.

        (IN THOUSANDS OF U.S. DOLLARS, EXCEPT SHARE AND PER SHARE DATA)

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    INCOME TAXES--Deferred income taxes result from temporary differences in the
recognition of expenses for tax and financial reporting purposes and are
accounted for in accordance with Financial Accounting Standards Board ("FASB")
Statement of Financial Accounting Standards No. 109 ("SFAS No. 109"), ACCOUNTING
FOR INCOME TAXES, which requires the liability method of computing deferred
income taxes. Under the liability method, deferred taxes are adjusted for tax
rate changes as they occur.

    SHARE SPLIT--On October 28, 1999, the Company's Board of Directors approved
a 2-for-1 share split. Retroactive restatement has been made to all share
amounts to reflect this share split.

    NET LOSS PER COMMON SHARE--Basic net loss per share is computed based on the
average number of common shares outstanding and diluted net loss per share is
computed based on the average number of common shares outstanding and, when
dilutive, potential common shares from share options and warrants to purchase
common shares using the treasury stock method and from convertible securities
using the if-converted basis.

    FOREIGN CURRENCY TRANSLATION--The Company's subsidiaries generally use the
U.S. dollar as the functional currency because their primary function, the sale
of advertising, is priced and billed in U.S. dollars. Accordingly, the financial
statements of the subsidiaries have been remeasured (or translated into U.S.
Dollars). The effects of foreign currency transactions and of remeasuring the
financial position and results of operations into U.S. dollars are included as
net gain or loss on foreign exchange, except for the Brazil subsidiary which
uses the local currency as its functional currency and the effects of the
translation is included in shareholders' equity.

    SHARE-BASED COMPENSATION--SFAS No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION, encourages, but does not require, companies to record compensation
cost for employees under share-based compensation plans at fair value. The
Company has chosen to continue to account for share-based compensation to
employees using the intrinsic value method as prescribed by Accounting
Principles Board Opinion ("APB") No. 25, ACCOUNTING FOR STOCK ISSUED TO
EMPLOYEES, and related interpretations. Accordingly, compensation cost for share
options issued to employees are measured as the excess, if any, of the fair
value of the Company's common shares at the date of grant over the amount an
employee must pay for the common shares.

    IRREVOCABLE CAPITAL CONTRIBUTIONS--Irrevocable capital contributions
represented capital contributions received from existing shareholders from time
to time to fund operations and carried no obligation on the part of the Company
to issue common shares or repay such contributions. On January 29, 1999, the
Company's Board of Directors approved the issuance of 6,400,000 common shares to
capitalize the $3,200 in irrevocable capital contributions.

    LONG-LIVED ASSETS--Long-lived assets are reviewed on an ongoing basis for
impairment based on comparison of carrying value against estimated undiscounted
future cash flows. If an impairment is identified, the assets carrying amount is
adjusted to fair value. No such adjustments were recorded for the years ended
December 31, 1997 and 1998 and during the nine months ended September 30, 1998
and 1999.

    NEW ACCOUNTING PRONOUNCEMENTS--In June 1998, the FASB issued SFAS No. 133,
ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. Among other
provisions, SFAS No. 133 establishes

accounting and reporting standards for derivative instruments and for hedging
activities. It also requires that an entity recognize all derivatives as either
assets or liabilities in the statement of financial position and measure those
instruments at fair value. SFAS No. 133 is effective for financial statements
for fiscal years beginning after June 15, 2000. Management is currently
evaluating the effect that adoption of SFAS No. 133 will have on the Company's
financial statements.

7. INCOME TAXES

    The Company has not provided for income taxes because of its operating loss
position. Statutory tax rates range from 20% to 35% depending on the particular
country. Deferred tax assets associated with the net operating loss
carryforwards amounted to $266, $1,412, and $5,536 as of December 31, 1997, 1998
and September 30, 1999, respectively. No deferred tax assets have been
recognized for changes in exchange rates for foreign subsidiaries whose
functional currency is the U.S. dollar. Because there is no assurance that the
Company will generate sufficient tax earnings to utilize its available tax
assets derived from loss carryforwards, a corresponding valuation allowance has
been established to offset deferred tax assets.

    No options have been forfeited as of December 31, 1998 and September 30,
1999.

    The Company applies APB No. 25 and related interpretations in accounting for
its share options plan to employees as described in Note 3. In connection with
the granting of share options in August and September 1999, the Company recorded
total deferred share-based compensation of approximately $7,785. Total deferred
share-based compensation is being amortized for financial reporting purposes
over the respective vesting periods of the share options. The amount recognized
as expense during the nine months ended September 30, 1999 amounted to
approximately $499.

    For purposes of pro forma disclosures prescribed by SFAS No. 123, the fair
value of the options granted in 1999 was estimated using the minimum value
method for nonpublic entities with the following assumptions: no dividend
yields; no volatility; risk-free interest rate of 7.0%; and an expected term of
3 years. If compensation cost had been determined based on the fair value at the
date of grant consistent with the requirement of SFAS No. 123, the Company's net
loss and comprehensive loss would have increased by approximately $8 and $63
during the year ended December 31, 1998 and nine months ended September 30,
1999, respectively.

12. CLASS A CONVERTIBLE PREFERRED SHARES

    On July 7, 1999, the Company completed a private placement of 5,477,088
Class A Convertible Preferred Shares (the "Class A Convertible Preferred
Shares") at $7.00186 per share for $35,837 (net of offering costs of $2,513)
under a stock purchase agreement. In addition, the Company has entered into an
arrangement whereby it agreed to issue 856,916 Class A Convertible Preferred
Shares in return for $6,000 in advertising time credit on media networks owned
and controlled by Washburn Enterprises, Inc., an affiliate of our shareholders.
Such advertising must be utilized during an eighteen-month period following the
closing date of the private placement. The Company will be required to issue and
deliver the number of Class A Convertible Preferred Shares equal to the
advertising time incurred on a quarterly basis. The Company currently
anticipates that it will recognize advertising expense based on the fair value
of such shares at the time of issuance. The Company has also agreed to purchase
at least $4,000 of advertising time on the media networks owned by affiliates of
Washburn Enterprises, Inc. in return for Washburn's commitment to purchase at
least $2,000 of advertising time on the Websites maintained by the Company and
its subsidiaries. As agreed in connection with the private placement, the
Company is required to pay annual monitoring fees to certain investor groups and
annual directors' fees to certain directors amounting to $600 per annum in the
aggregate. In addition, the Company issued to the placement agent a warrant
exercisable for the purchase of approximately 239,936 common shares for $1.

    The following are principal terms of the Class A Convertible Preferred
Shares: (a) cumulative preferential dividends at the annual rate of 8% on the
liquidation preference per share, payable quarterly in cash or at the option of
the Board of Directors, in additional Class A Convertible Preferred Shares;
(b) mandatory redemption by the Company in 2004 (five years after issuance) at a
price equal to the liquidation preference per share plus accrued and unpaid
cumulative dividends; (c) convertible into two common shares of the Company at
any time at the option of the holder or automatically upon the closing of this
offering. For purposes of determining the number of common shares issuable upon
conversion, each Class A Convertible Preferred Share will be valued at
liquidation preference, which will be divided by the conversion price in effect
on the date of conversion; (d) the right of certain shareholders holding a
certain minimum number of outstanding Class A Convertible Preferred Shares to
appoint a maximum of three directors to the Company's Board of Directors;
(e) holders of Class A Convertible Preferred Shares have the right to vote,
together with the holders of outstanding common shares, except as otherwise
required by British Virgin Islands law, on all matters on which holders of
common shares are entitled to vote. Each holder of Class A Convertible Preferred
Shares will have the right to cast one vote for each whole share which would be
issued to such holder upon conversion of such holder's Class A Convertible
Preferred Shares to common shares, assuming that such conversion were to occur
on the date immediately prior to the record date for the determination of
shareholders entitled to vote; and (f) upon any liquidation, dissolution or
winding up of the Company, the holders of Class A Convertible Preferred Shares
are entitled to be paid an amount equal to the liquidation preference for each
share out of the assets of the Company before any distribution is made to any
common shares or other junior shares.

    PREFERRED STOCK/BARTER ARRANGEMENT--On August 31, 1999, the Company entered
into an agreement relating to a three-year investment and reciprocal advertising
arrangement with TV Azteca, S.A. de C.V. ("TV Azteca"), Mexico's second largest
television network. Under this agreement, the Company will receive, over a
three-year period beginning in July 1999, $3,500 of advertising time on TV
Azteca's networks (which amounts shall be based on rates actually charged to
similarly situated clients of TV

Azteca at the time), in return for 355,478 shares of Class A Convertible
Preferred Shares issued on August 31, 1999 at the same price per share as in the
July 1999 private placement. At September 30, 1999, approximately $2,500 of
prepaid advertising was included in other assets in the accompanying
consolidated balance sheet. In addition, as of September 30, 1999, TV Azteca has
not provided any advertising time on its network to the Company relating to this
agreement.

13. COMMITMENTS AND CONTINGENCIES

    The Company has entered into a strategic alliance, for a term of two years

player granted the Company the exclusive right to utilize such player's name,
likeness or any derivative thereof via the Internet within the Company's web
sites for the development of joint marketing campaigns, promotions, research and
e-commerce operations. The Company will pay this baseball player $1,000 cash in

shares at the time that such shares are issued.

    The Company has entered into employment agreements with various members of
senior management for periods extending for three years. Minimum annual
compensation approximates $1,024 in the aggregate.

    The Company leases telecommunication links with rental commitments of

our current headquarters in Buenos Aires ($84,000) per year, as well as rental
of our new headquarters in Buenos Aires ($228,000 per year).

1. BACKGROUND

    On August 4, 1999, IMPSAT Corporation ("IMPSAT") entered into a framework
agreement with El Sitio, Inc. ("El Sitio") for the sale of IMPSAT's retail
dial-up access customers in Argentina, Brazil and Colombia for approximately
$21,500 and the related purchase by IMPSAT of 3,070,615 of El Sitio's Class A
convertible preferred shares for $21,500. In connection with these transactions,
El Sitio will also enter into telecommunications services agreements with
subsidiaries of IMPSAT under which they will provide El Sitio with
telecommunications infrastructure. The transactions contemplated by the
framework agreement are subject to the negotiation of definitive documentation
and various other conditions, including governmental approvals.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    BASIS OF PRESENTATION--The retail dial-up access business (the "Business")
is not a "stand-alone" division or subsidiary of IMPSAT and was not generally
accounted for separately. As a result, the distinct and separate accounts
necessary to present an individual balance sheet, income statement and cash flow
statement of the Business have not been maintained. The financial information
presented is limited to the statement of assets to be sold by IMPSAT and it is
not intended to present the financial position of the Business.

    The statement of historical net assets to be sold include property and
equipment and certain accrued liabilities being acquired in accordance with the
contractual terms. Property and equipment consist of computer and office
equipment in Brazil and is recorded at cost. Depreciation is calculated using
the straight line method over the useful life which range from five to ten
years. Accumulated depreciation amounted to $130 at September 30, 1999.

3. SUBSEQUENT EVENTS

    Effective October 7, 1999, the Brazil sale was completed at a sale price of
$12,300. Effective November 5, 1999, the Argentina sale was completed at a sale
price of $6,200. The Colombia sale, which is subject to governmental approvals,
is expected to be completed before the end of 1999.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Shareholders of IMPSAT S.A.:

    We have audited the accompanying statements of net revenues and direct costs
and expenses of IMPSAT S.A.'s retail dial-up access business in Argentina (the
"Business"), for the years ended December 31, 1997 and 1998 and the nine months
ended September 30, 1999. These statements of net revenues and direct costs and
expenses are the responsibility of IMPSAT S.A.'s management. Our responsibility
is to express an opinion on these statements of net revenues and direct costs
and expenses based on our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
statements of net revenues and direct costs and expenses are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the statements of net revenues and direct costs
and expenses. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
statements of net revenues and direct costs and expenses presentation. We
believe that our audits provide a reasonable basis for our opinion.

    As discussed in Note 2 to the statements of net revenues and direct costs
and expenses, the Business comprises IMPSAT S.A.'s retail dial-up access
business in Argentina based on management's estimates. As a result, the net
revenues and direct costs and expenses of the Business may not be indicative of
conditions that would have existed or results that would have occurred had the
Business operated as an unaffiliated entity.

    In our opinion, the statements of net revenues and direct costs and expenses
present fairly, in all material respects, the net revenues and direct costs and
expenses of the Business for the years ended December 31, 1997 and 1998 and the
nine months ended September 30, 1999 in conformity with accounting principles
generally accepted in the United States of America.

       NOTES TO STATEMENTS OF NET REVENUES AND DIRECT COSTS AND EXPENSES

                         (IN THOUSANDS OF U.S. DOLLARS)

1. OPERATIONS

    On August 4, 1999, El Sitio, Inc. ("El Sitio") entered into a framework
agreement with IMPSAT Corporation ("IMPSAT") for the purchase of IMPSAT's retail
dial-up access customers in Argentina, Brazil and Colombia for approximately
$21,500 and the related purchase by IMPSAT of 3,070,615 of El Sitio's Class A
convertible preferred shares for $21,500. In connection with these transactions,
El Sitio will also enter into a telecommunications services agreement with
IMPSAT under which it will provide El Sitio with telecommunications
infrastructure.

    Effective November 5, 1999, the transaction for the Argentina retail dial-up
business was closed for $6,200.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    BASIS OF PRESENTATION--The retail dial-up access business in Argentina (the
"Business") was part of the total Internet services provided by IMPSAT S.A.,
which also included dial-up access to corporate customers. The Business was not
a "stand-alone" division or subsidiary of IMPSAT S.A. and was not generally
accounted for separately. As a result, the distinct and separate accounts
necessary to present an individual balance sheet, income statement and cash flow
statement of the Business have not been maintained. The Business did not
maintain its own stand-alone treasury, legal, financial, information systems and
other similar corporate support functions. The financial information presented
is limited to the statement of net revenues and direct costs and expenses.

    REVENUES--The retail dial-up access business represented 60% of IMPSAT's
S.A.'s total revenues associated with Internet services for the years ended
December 31, 1997 and 1998 and for the nine months ended September 30, 1998 and
64% for the nine months ended September 30, 1999. These percentages were
calculated based on information derived from the general ledger accounts as
follows: actual revenues for retail dial-up and corporate dial-up accounts were
specifically identified and then the revenues for corporate accounts were
subtracted from total actual revenues, resulting in net revenues associated with
retail dial-up customers.

    DIRECT COSTS AND EXPENSES--IMPSAT S.A.'s management allocated direct costs
and expenses (other than credit card fees and bad debt expenses) to the retail
dial-up access business based on the proportionate share of retail dial-up
revenues to total Internet revenues.

    Credit card fee and bad debt expenses associated with the retail dial-up
access business were specifically identified based upon billing and customer
information provided by IMPSAT S.A.'s management information system.

    These allocations were based on, among other things, subscriber statistics
and the shared use by the retail dial-up and corporate dial-up portions of
IMPSAT S.A.'s assets and resources such as the following: call center, technical
and sales and marketing personnel; equipment such as servers, routers and
modems; and supplies. These allocations are believed to be reasonable under the
circumstances. However, the Business may not be indicative of conditions that
would have existed or results that would have occurred had the Business operated
as an unaffiliated entity.

    The same allocation methodologies were used for each of the financial years
and periods presented in these statements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    A statement of cash flow is not being presented as the Business does not
maintain its own cash accounts and components, such as the changes in working
capital, are not available to prepare the cash flow information.

    INTERIM FINANCIAL INFORMATION--The unaudited statement of net revenues and
direct costs and expenses for the nine months ended September 30, 1998 has been
prepared on the same basis as the audited annual statements of net revenues and
direct costs and expenses. In the opinion of management, such unaudited
statement of net revenues and direct costs and expenses includes all adjustments
(consisting only of normal recurring adjustments) necessary to present fairly
the results for such period. The results of operations for the nine months ended
September 30, 1998 are not necessarily indicative of the results of operations
to be expected for the full fiscal year or for any future period.

    REVENUE RECOGNITION--Revenues represent month-to-month subscriptions for
pre-paid and per-minute usage of access levels. Subscription revenues are
recognized over the period that services are provided.

    USE OF ESTIMATES--The preparation of the statements of net revenues and
direct costs and expenses in conformity with generally accepted accounting
principles in the United States requires management to make certain estimates
and assumptions that effect the amounts of the reported amounts of net revenues
and direct costs and expenses during the reporting period. Actual results could
differ from those estimates.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Shareholders of MANDIC INTERNET LTDA.:

    We have audited the accompanying statements of net revenues and direct costs
and expenses of MANDIC INTERNET LTDA.'s (formerly known as MANDIC.COM LTDA.)
retail dial-up access business in Brazil (the "Business") for the years ended
December 31, 1997 and 1998 and the nine months ended September 30, 1999. These
statements of net revenues and direct costs and expenses are the responsibility
of MANDIC INTERNET LTDA.'s management. Our responsibility is to express an
opinion on these statements of net revenues and direct costs and expenses based
on our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
statements of net revenues and direct costs and expenses are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the statements of net revenues and direct costs
and expenses. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
statements of net revenues and direct costs and expenses presentation. We
believe that our audits provide a reasonable basis for our opinion.

    As discussed in Note 2 to the statements of net revenues and direct costs
and expenses, the Business comprises MANDIC INTERNET LTDA.'s retail dial-up
access business in Brazil. Direct costs and expenses included in the statements
of net revenues and direct costs and expenses have been allocated to the retail
dial-up access business based on the proportionate share of retail dial-up
revenues. As a result, the net revenues and direct costs and expenses of the
Business may not be indicative of conditions that would have existed or results
that would have occurred had the Business operated as an unaffiliated entity.

    In our opinion, the statements of net revenues and direct costs and expenses
present fairly, in all material respects, the net revenues and direct costs and
expenses of the Business for the years ended December 31, 1997 and 1998 and the
nine months ended September 30, 1999 in conformity with accounting principles
generally accepted in the United States of America.

                         (IN THOUSANDS OF U.S. DOLLARS)

1. OPERATIONS

    On August 4, 1999, El Sitio, Inc. ("El Sitio") entered into a framework
agreement with IMPSAT Corporation ("IMPSAT") for the purchase of IMPSAT's retail
dial-up access customers in Argentina, Brazil and Colombia for approximately
$21,500 and the related purchase by IMPSAT of 3,070,615 of El Sitio's Class A
convertible preferred shares for $21,500. In connection with these transactions,
El Sitio has also entered into a telecommunications services agreement with an
affiliate of IMPSAT under which it will provide El Sitio with telecommunications
infrastructure.

    Effective October 6, 1999, the transaction for the Brazil retail dial-up
access business was closed for $12,300.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    BASIS OF PRESENTATION--The retail dial-up access business in Brazil (the
"Business") is not a "stand-alone" division or subsidiary of MANDIC
INTERNET LTDA. and was not generally accounted for separately. As a result, the
distinct and separate accounts necessary to present an individual balance sheet,
income statement and cash flow statement of the Business have not been
maintained. The Business does not maintain its own stand-alone treasury, legal,
financial, information systems and other similar corporate support functions.
The financial information presented is limited to the statement of net revenues
and direct costs and expenses.

    For purposes of preparing these statements, revenues of MANDIC INTERNET
LTDA's retail dial up access businesses were specifically identified and
obtained from the general ledger. Direct costs and expenses associated with
MANDIC INTERNET LTDA.'s dial-up access businesses have been allocated to the
Business as follows:

    COST OF SERVICES:

    - telecommunications services expenses reflect direct expenses paid for
      telecommunication links to EMBRATEL, a telecommunications services
      provider. These expenses will be equivalent to El Sitio's cost of
      telecommunication links under El Sitio's new service agreement with a
      subsidiary of IMPSAT for Brazil;

    - salaries and wages were allocated to the retail dial-up access business
      based on the number of managers and employees responsible for the retail
      dial-up access business, as a percentage of the total number of managers
      and employees employed in the entire (i.e., retail plus corporate) dial-up
      access business of IMPSAT in Brazil; and

    - expenses relating to the call center were specifically identified and
      obtained from the general ledger.

    MARKETING AND SALES:

    - credit card fees were specifically identified and obtained from the
      general ledger; and

    - advertising expenses for the Business were based on management's
      good-faith estimates.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    CORPORATE, GENERAL AND ADMINISTRATIVE:

    - depreciation and amortization expense was computed based on the assets
      specifically identified by management as being used in the retail dial-up
      access business;

    - outsourced services were specifically identified and obtained from the
      general ledger; and

    - rent, utilities and services were allocated based on the space utilized by
      the retail dial-up access business, as a percentage of the total space
      used by the entire (i.e., retail plus corporate) dial-up access business.

    Of total retail dial-up access direct costs and expenses for Brazil,
approximately 47% were directly obtained from the general ledger for 1997, 68%
in 1998, 63% in the nine months ended September 30, 1998 and 60% in the nine
months ended September 30, 1999. MANDIC INTERNET LTDA.'s retail dial-up
operations in Brazil accounts for approximately 52,000 of the approximately
73,000 retail dial-up access customers which El Sitio is acquiring from IMPSAT.
However, the Business may not be indicative of conditions that would have
existed or results that would have occurred had the Business operated as an
unaffiliated entity.

    The same allocation methodologies were used for each of the financial years
and periods presented in these statements.

    A statement of cash flow is not being presented as the Business does not
maintain its own cash accounts and components, such as the changes in working
capital, are not available to prepare the cash flow information.

    INTERIM FINANCIAL INFORMATION--The unaudited statement of net revenues and
direct costs and expenses for the nine months ended September 30, 1998 has been
prepared on the same basis as the audited annual statement of net revenues and
direct costs and expenses. In the opinion of management, such unaudited annual
statement of net revenues and direct costs and expenses includes all adjustments
(consisting only of normal recurring adjustments) necessary to present fairly
the results for such period. The operating results for the nine months ended
September 30, 1998 are not necessarily indicative of the operating results to be
expected for the full fiscal year or for any future period.

    REVENUE RECOGNITION--Revenues represent month-to-month subscriptions for
pre-paid and per-minute usage of access levels. Subscription revenues are
recognized over the period that services are provided.

    USE OF ESTIMATES--The preparation of the statements of net revenues and
direct costs and expenses in conformity with generally accepted accounting
principles in the United States of America requires management to make certain
estimates and assumptions that effect the amounts of the reported amounts of net
revenues and direct costs and expenses during the reporting period. Actual
results could differ from those estimates.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Shareholders of IMPSAT S.A.:

    We have audited the accompanying statements of net revenues and direct costs
and expenses of IMPSAT S.A.'s retail dial-up access business in Colombia (the
"Business") for the years ended December 31, 1997 and 1998 and the nine months
ended September 30, 1999. These statements of net revenues and direct costs and
expenses are the responsibility of IMPSAT S.A.'s management. Our responsibility
is to express an opinion on these statements of net revenues and direct costs
and expenses based on our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
statements of net revenues and direct costs and expenses are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the statements of net revenues and direct costs
and expenses. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
statements of net revenues and direct costs and expenses presentation. We
believe that our audits provide a reasonable basis for our opinion.

    As discussed in Note 2 to the statements of net revenues and direct costs
and expenses, the Business comprises IMPSAT S.A.'s retail dial-up access
business in Colombia. Costs incurred directly are included in the statements of
net revenues and direct costs and expenses and operating expenses have been
allocated to the retail dial-up access business based on management's estimates.
As a result, the net revenues and direct costs and expenses of the Business may
not be indicative of conditions that would have existed or results that would
have occurred had the Business operated as an unaffiliated entity.

    In our opinion, the statements of net revenues and direct costs and expenses
present fairly, in all material respects, the net revenues and direct costs and
expenses of the Business for the years ended December 31, 1997 and 1998 and the
nine months ended September 30, 1999 in conformity with accounting principles
generally accepted in the United States of America.

1. OPERATIONS

    On August 4, 1999, El Sitio, Inc. ("El Sitio") entered into a framework
agreement with IMPSAT Corporation ("IMPSAT") for the purchase of IMPSAT's retail
dial-up access customers in Argentina, Brazil and Colombia for $21,500 and the
related purchase by IMPSAT of 3,070,615 Class A Convertible Preferred Shares of
El Sitio for $21,500. In connection with these transactions, El Sitio will also
enter into a telecommunications services agreement with an affiliate of IMPSAT
under which it will provide El Sitio with telecommunications infrastructure.

    The closing of the acquisition of retail dial-up access customers of IMPSAT
in Colombia is subject to the negotiation of definitive documentation and
various other conditions, including governmental approvals, and accordingly,
there can be no assurance that this transaction will be completed. Subject to
the satisfaction of these conditions, the transaction is expected to be
consummated by the end of 1999.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    BASIS OF PRESENTATION--The retail dial-up access business in Colombia (the
"Business") is not a "stand-alone" division or subsidiary of IMPSAT S.A. and was
not generally accounted for separately. As a result, the distinct and separate
accounts necessary to present an individual balance sheet, income statement and
cash flow statement of the Business have not been maintained. The Business does
not maintain its own stand-alone treasury, legal, financial, information systems
and other similar corporate support functions. The financial information
presented is limited to the statement of net revenues and direct costs and
expenses.

    For purposes of preparing these statements, revenues of IMPSAT S.A.'s retail
dial-up access business were specifically identified and obtained from the
general ledger. Product, content and technology costs were also specifically
identified and obtained from the general ledger. Operating expenses such as
marketing and sales and corporate, general and administrative associated with
IMPSAT S.A.'s retail dial-up access business have been allocated based on
management's estimates.

    Product, content and technology expenses accounted for 67% of expenses in
Colombia in 1997, 68% in 1998, 67% in the nine months ended September 30, 1998
and 71% in the nine months ended September 30, 1999.

    IMPSAT S.A.'s management allocated other direct costs and expenses related
to the Business based on the proportionate share of retail Internet revenue to
total Internet revenue. These allocations are based on, among other things,
subscriber statistics and the shared use by the retail dial-up and corporate
dial-up portions of IMPSAT S.A.'s assets and resources such as the following:
call center, technical and sales and marketing personnel; equipment such as
servers, routers and modems; and supplies. These allocations are believed to be
reasonable under the circumstances. However, the Business' may not be indicative
of conditions that would have existed or results that would have occurred had
the Business operated as an unaffiliated entity.

    The same allocation methodologies were used for each of the financial years
and periods presented in these statements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    A statement of cash flow is not being presented as the Business does not
maintain its own cash accounts and components, such as the changes in working
capital, are not available to prepare the cash flow information.

    INTERIM FINANCIAL INFORMATION--The unaudited statement of net revenues and
direct costs and expenses for the nine months ended September 30, 1998 has been
prepared on the same basis as the audited annual statements of net revenues and
direct costs and expenses. In the opinion of management, such unaudited
statement of net revenues and direct costs and expenses includes all adjustments
(consisting only of normal recurring adjustments) necessary to present fairly
the results for such period. The operating results for the nine months ended
September 30, 1998 are not necessarily indicative of the operating results to be
expected for the full fiscal year or for any future period.

    REVENUE RECOGNITION--Revenues represent month-to-month subscriptions for
pre-paid and per-minute usage of access levels. Subscription revenues are
recognized over the period that services are provided.

    CURRENCY TRANSLATIONS--The statements of net revenues and direct costs and
expenses of the Company contain currency translations of Colombian peso amounts
to U.S. dollars at the exchange rate at the date of the transactions reported by
the Superintendency of Banking. No representation is made that the Colombian
peso amounts have been, could have been, or could be converted into U.S.
dollars, at such a rate or any other rate.

    USE OF ESTIMATES--The preparation of the statements of net revenues and
direct costs and expenses in conformity with generally accepted accounting
principles in the United States of America requires management to make certain
estimates and assumptions that effect the amounts of the reported amounts of net
revenues and direct costs and expenses during the reporting period. Actual
results could differ from those estimates.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

    The following sets forth unaudited pro forma consolidated financial
information for our company at September 30, 1999 and for the year ended
December 31, 1998 and the nine months ended September 30, 1999 giving effect to
(i) our completed and pending acquisitions of the retail dial-up access
customers in Argentina, Brazil and Colombia from IMPSAT Corporation for
approximately $21.5 million in the aggregate and the related purchase by IMPSAT
Corporation of 3,070,615 Class A convertible preferred shares for $21.5 million
and (ii) our private placement in mid-November 1999 of 1,111,111 Class B
convertible preferred shares for an aggregate purchase price of $10.0 million in
cash.

    The pro forma financial information assumes that the above transactions had
been completed at January 1, 1998 and January 1, 1999 in the case of the pro
forma statement of operations data for the year ended December 31, 1998 and the
nine months ended September 30, 1999, respectively, and at September 30, 1999 in
the case of the pro forma balance sheet data.

    The pro forma financial information does not purport to present our
financial condition or results of operations had these transactions occurred on
those dates and is not necessarily indicative of our results of operations for
future periods.

    The historical financial information for our company and for the dial-up
access customers in Argentina, Brazil and Colombia of IMPSAT Corporation has
been derived from the financial statements included in this prospectus. The pro
forma adjustments relating to the acquisition of these retail dial-up access
customers are based upon available information and assumptions that we consider
reasonable under the circumstances. Final adjustments could differ from these
adjustments.

       for $12.3 million and Colombia for $3.0 million for a total purchase
       price of $21.5 million. The purchase price has been allocated to the
       assets acquired and liabilities assumed based on management's preliminary
       estimates of fair value. In connection with these acquisitions, we will
       enter into agreements for telecommunication services to be provided to us

       impairment based on comparison of carrying value against estimated
       undiscounted future cash flows. If an impairment is identified, the
       assets carrying amount will be adjusted to fair value.

    (d) Reflects the purchase of 3,070,615 Class A convertible preferred shares

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    The International Business Companies Act, 1984 of the British Virgin Islands
permits an international business company to indemnify directors and officers
and permits an international business company to acquire liability insurance for
directors and officers.

    Under Sections 118 through 123 of our articles of association, our company
is empowered to indemnify our directors and officers as follows:

    "118. Subject to the limitations hereinafter provided, the Company may
          indemnify against all expenses, including legal fees, and against all
          judgments, fines and amounts paid in settlement and reasonably
          incurred in connection with legal, administrative or investigative
          proceedings any person who

         (a) is or was a party or is threatened to be made a party to any
             threatened, pending or completed proceedings, whether civil,
             criminal, administrative or investigative, by reason of the fact
             that the person is or was a director, an officer or a liquidator of
             the Company; or

         (b) is or was, at the request of the Company, serving as a director,
             officer or liquidator of, or in any other capacity is or was acting
             for, another company or a partnership, joint venture, trust or
             other enterprise.

    119. The Company may only indemnify a person if the person acted honestly
         and in good faith with a view to the best interests of the Company and,
         in the case of criminal proceedings, the person had no reasonable cause
         to believe that his conduct was unlawful.

    120. The decision of the directors as to whether the person acted honestly
         and in good faith and with a view to the best interests of the Company
         and as to whether the person had no reasonable cause to believe that
         his conduct was unlawful is, in the absence of fraud, sufficient for
         the purposes of these Articles, unless a question of law is involved.

                                      II-1
<PAGE>
    121. The termination of any proceedings by any judgment, order, settlement,
         conviction or the entering of a nolle prosequi does not, by itself,
         create a presumption that the person did not act honestly and in good
         faith and with a view to the best interests of the Company or that the
         person had reasonable cause to believe that his conduct was unlawful.

    122. If a person to be indemnified has been successful in defense of any
         proceedings referred to above the person is entitled to be indemnified
         against all expenses, including legal fees, and against all judgments,
         fines and amounts paid in settlement and reasonably incurred by the
         person in connection with the proceedings.

    123. The Company may purchase and maintain insurance in relation to any
         person who is or was a director, an officer or a liquidator of the
         Company, or who at the request of the Company is or was serving as a
         director, an officer or a liquidator of, or in any other capacity is or
         was acting for, another company or a partnership, joint venture, trust
         or other enterprise, against any liability asserted against the person
         and incurred by the person in that capacity, whether or not the Company
         has or would have had the power to indemnify the person against the
         liability as provided in these Articles."

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

    On July 7, 1999, we completed the private placement of 6,334,004 Class A
convertible preferred shares for a total purchase price of $44.4 million,
consisting of 5,477,088 shares sold for $38.4 million in cash and 856,916 shares
to be issued on a quarterly basis through 2001 in exchange for $6.0 million in
non-cash advertising time credits. Strategic investors included Hicks, Muse,
Tate & Furst Incorporated, and the Cisneros Group of Companies (through IAMP (El
Sitio) Investments Ltd.) and GC Companies Inc. (through GCC Investments, LLC).
Some of our initial investors purchased $6.5 million of our Class A convertible
preferred shares as part of the private placement. The private placement was
exempt from registration under the Securities Act in reliance upon the exemption
provided by Section 4(2) under that Act.

    In August 1999, we entered into a framework agreement with IMPSAT
Corporation, a leading provider of private networks of integrated data and voice
communications systems in a number of countries in Latin America, to acquire its
retail dial-up access customers in Argentina, Brazil and Colombia. Under this
Agreement, we have acquired or will acquire these customers for an aggregate of
$21.5 million. IMPSAT Corporation will, in turn, purchase a total of 3,070,615
Class A convertible preferred shares for approximately $21.5 million. The
Argentine and Brazilian acquisitions were consummated in October and
November 1999, respectively, and we expect to close the acquisition in Colombia
in fourth quarter 1999. The sale of these shares to IMPSAT Corporation was
exempt from registration under the Securities Act in reliance upon
Regulation S, and in the alternative, Section 4(2) under that Act.

    In mid-November 1999, we completed a private placement of 1,111,111 Class B
convertible preferred shares for a purchase price of $10.0 million in cash, or
$9.00 per Class B convertible preferred share. Purchasers of the Class B
convertible preferred shares consisted of Intel Atlantic, Inc., a subsidiary of
Intel Corporation, and Latinvest Asset Management do Brasil, Ltda., an affiliate
of Globalvest Management Company, L.P. Each Class B convertible preferred share
will automatically convert, on the date six months following the closing date of
this offering, into one common share. The private placement was exempt from
registration under the Securities Act in reliance upon the exemption provided by
Section 4(2) under that Act.

ITEM 17. UNDERTAKINGS.

    (a) The undersigned registrant hereby undertakes to provide to the
underwriters, at the closing specified in the underwriting agreement,
certificates in such denominations and registered in such names as required by
the underwriter to permit prompt delivery to each purchaser.

    (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 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 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.

    (c) 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 purposes 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.

                  consolidated financial information included in the Prospectus
                  are reasonable and the adjustments used therein are
                  appropriate to give effect to the transactions or
                  circumstances referred to therein.

                  Section 27A of the Securities Act and Section 21E of the
                  Exchange Act) contained in the Prospectus has been made or
                  reaffirmed without a reasonable basis or has been disclosed
                  other than in good faith.

                           (q) Neither the Company nor any of its subsidiaries
                  owns any real property; the Company and each of its

                  liens, encumbrances and defects except such as are described
                  in the Prospectus or such as do not materially affect the
                  value of such property and do not materially interfere with
                  the use made and proposed to be made of such property by the
                  Company and its subsidiaries; and all real property and
                  buildings held under lease by the Company and its subsidiaries
                  are held by them under valid, subsisting and enforceable
                  leases, with such exceptions as are not material and do not
                  interfere with the use made and proposed to be made of such
                  property and buildings by the Company and its subsidiaries.

                           (r) Except as set forth in the Prospectus, each of
                  the Company and its subsidiaries possesses adequate

                  issued by appropriate governmental agencies or bodies
                  necessary to conduct its business as presently conducted and
                  as proposed to be conducted, and has not received any notice
                  of proceedings relating to the revocation or modification of
                  any such certificate, authority, approval, license or permit.

                           (s) The Company and each of its subsidiaries carry,
                  or are covered by, insurance from insurers of recognized
                  financial responsibility in such amounts and covering such
                  risks as is adequate for the conduct of their respective
                  businesses and the value of their respective properties and as
                  is prudent and customary for companies engaged in similar
                  businesses in similar industries; all policies of insurance
                  insuring the Company or any of its subsidiaries or their
                  respective businesses, assets, directors, officers and
                  employees are in full force and effect; the Company and its
                  subsidiaries are in compliance with the terms of such policies
                  and instruments in all material respects; and there are no
                  claims by the Company or any of its subsidiaries under any
                  such policy or instrument as to which any insurance company is
                  denying liability or defending under a reservation of rights
                  clause; neither the Company nor any such subsidiary has been
                  refused any insurance coverage sought or applied for; and
                  neither the Company nor any such subsidiary has any reason to
                  believe that it will not be able to renew its existing
                  insurance coverage as and when such coverage expires or to
                  obtain similar coverage from similar insurers as may be
                  necessary to continue its business at a cost that could not
                  reasonably be expected to have a Material Adverse Effect.

                           (t) Except as set forth in the Prospectus, the
                  Company and each of its subsidiaries own or possess adequate
                  rights to use all material uniform resource locators (URLs),

                  names, trademark registrations, service mark registrations,
                  copyrights and licenses necessary for them to conduct their
                  respective businesses as now conducted and as proposed to be
                  conducted and have no reason to believe that the conduct of
                  their

<PAGE>
                                                                               8


                  respective businesses will conflict with, and have not
                  received any notice of any claim of conflict with, any such
                  rights of any other person or entity.

                           (u) There are no legal or governmental proceedings
                  pending to which the Company or any of its subsidiaries is a
                  party or of which any property or assets of the Company or any
                  of its subsidiaries is the subject which, if determined
                  adversely to the Company or any of its subsidiaries, could
                  reasonably be expected to have a Material Adverse Effect; and
                  to the Company's knowledge, no such proceedings are threatened
                  or contemplated by any governmental agency or body or
                  threatened by any other person or entity.

                           (v) There are no contracts or other documents which
                  are required to be described in the Prospectus or filed as
                  exhibits to either of the Registration Statements by the
                  Securities Act or by the Rules and Regulations which have not
                  been described in the Prospectus or filed as exhibits to the
                  Registration Statements.

                           (w) No relationship, direct or indirect, exists
                  between or among the Company or any of its subsidiaries on the
                  one hand, and the directors, officers, shareholders, customers
                  or suppliers of the Company or such subsidiary, as the case
                  may be, on the other hand, which is required to be described
                  in the Prospectus which is not so described.

                           (x) No labor disturbance by the employees of the
                  Company or its subsidiaries exists or, to the knowledge of the
                  Company, is imminent, which could reasonably be expected to
                  have a Material Adverse Effect. Each of the Company and its
                  subsidiaries is in compliance in all material respects with
                  all applicable laws in their respective jurisdictions relating
                  to employees (including, without limitation, laws relating to
                  pension contributions and obligations).

                           (y) Each of the Company and its subsidiaries has
                  filed with all appropriate taxing authorities all income,
                  franchise or other tax returns required to be filed through
                  the date hereof and has paid all taxes due thereon; each such
                  tax return, report or other information, was, when filed,
                  accurate and complete in all material respects; and no tax
                  deficiency has been determined adversely to the Company or any
                  of its subsidiaries which has had (nor does the Company have
                  any knowledge of any tax deficiency which, if determined
                  adversely to the Company or any of its subsidiaries, could
                  reasonably be expected to have) a Material Adverse Effect.

                           (z) All dividends and other distributions properly
                  declared and payable on the Shares may under the current laws
                  and regulations of the British Virgin Islands be paid in U.S.
                  dollars that may be freely transferred from or out of the
                  British Virgin Islands without the necessity of obtaining any
                  consents, approvals, authorizations, orders or clearances from
                  or registering with any governmental agency or body or court

                  irrevocably appointed CT Corporation System as its authorized

                           (ii) As of the date hereof, neither the Company nor
                  any of its subsidiaries is, or intends to conduct its business
                  activities in such a manner that it would become, and, after
                  giving effect to the transactions contemplated hereunder,
                  neither the Company nor any of its subsidiaries will be
                  required to be registered as, an "investment company" pursuant
                  to the U.S. Investment Company Act of 1940, as amended (the
                  "Investment Company Act"), and the rules and regulations of
                  the Commission thereunder.

                           (jj) Under the laws of the British Virgin Islands and

                  jurisdiction of any New York state or U.S. federal court

                                                                              11


                           (kk) Neither the Company nor any of its subsidiaries
                  has (i) violated any material environmental statute, rule,
                  regulation, order, judgment, decree or permit in any
                  jurisdiction in which the Company or such subsidiary conducts
                  any business or owns or holds any properties or assets or (ii)
                  received notice of any actual or potential liability for the
                  investigation or remediation of any disposal or release of
                  hazardous or toxic substance or wastes, pollutants or
                  contaminants, except where such violation or liability could
                  not reasonably be expected to have a Material Adverse Effect.

                           (ll) The acquisitions of the retail dial-up access
                  customers and related assets of the IMPSAT Entities in
                  Argentina and Brazil have been completed in accordance with
                  the terms set forth in the Prospectus. Other than the pending
                  acquisition of the retail dial-up access customers and related
                  assets of IMPSAT S.A. (Colombia), there are no material
                  acquisitions of businesses or assets by the Company or any of
                  its subsidiaries pending or currently being negotiated.

                           (mm) Based on its projected income and assets
                  (including goodwill), which it believes to be reasonable, the
                  nature of the Company's business and assets and taking into
                  account the receipt of proceeds from the offering and sale of
                  the Shares, the Company believes that it will not be
                  classified as a passive foreign investment company ("PFIC")
                  within the meaning of Section 1297(a) of the U.S. Internal
                  Revenue Code of 1986, as amended (the "Internal Revenue
                  Code"), including the regulations and rulings and
                  interpretations thereunder, for its current taxable year. The
                  Company intends to conduct its business activities in an
                  effort to reduce the risk of its classification as a PFIC.

                           (nn) Any reprogramming required to permit the proper
                  functioning, in and following the year 2000, of the Company's
                  and its subsidiaries' (i) computer systems and (ii) equipment
                  containing embedded microchips (including systems and
                  equipment supplied by others or with which the Company's
                  systems interface) and the testing of all such systems and
                  equipment, as so reprogrammed, will be completed by November
                  30, 1999. The cost to the Company of such reprogramming and
                  testing and of the reasonably foreseeable consequences of year
                  2000 to the Company (including, without limitation,
                  reprogramming errors and the failure of others' systems or
                  equipment) will not result in a Material Adverse Effect.
                  Except for such of the reprogramming referred to in the
                  preceding sentence as may be necessary, the computer and
                  management information systems of the Company and its
                  subsidiaries are and, with ordinary course upgrading and
                  maintenance, will continue to be, sufficient to permit the
                  Company to conduct its business without a Material Adverse
                  Effect.

                           (oo) None of the Company and any of its subsidiaries,
                  or any of their respective affiliates, does business with the
                  government of Cuba or with any person or affiliate located in
                  Cuba.

                           (pp) Neither the Company nor any of its officers,
                  directors or affiliates has taken, directly or indirectly, any
                  action designed to stabilize or manipulate the trading price
                  of the Common Shares, or that might reasonably be expected to
                  cause or result in stabilization or manipulation of the
                  trading price of the Common Shares.

                  2. PURCHASE OF THE SHARES BY THE UNDERWRITERS.

                  On the basis of the representations and warranties contained
in, and subject to the terms and conditions of, this Agreement, the Company
agrees to sell 8,200,000 Firm Shares to the several Underwriters, and each of
the Underwriters, severally and not jointly, agrees to purchase the number of
Firm Shares set opposite that Underwriter's name in Schedule 1 hereto. The
respective purchase obligations of the Underwriters with respect to the Firm
Shares shall be rounded among the Underwriters to avoid fractional shares, as
the Representatives may determine.

                  In addition, the Company grants to the Underwriters an option
to purchase up to 1,230,000 Option Shares. Such option is granted solely for the
purpose of covering over-allotments in the sale of Firm Shares and is
exercisable as provided in Section 4 hereof. The Option Shares shall be
purchased severally for the account of the Underwriters in proportion to the
number of Firm Shares set opposite the name of such Underwriters in Schedule 1
hereto. The respective purchase obligations of each Underwriter with respect to
the Option Shares shall be adjusted by the Representatives so that no
Underwriter shall be obligated to purchase Option Shares other than in 100-share
amounts.

                  The purchase price to be paid by the Underwriters for the Firm
Shares and any Option Shares shall be U.S.$__.00 per share.

                  The Company shall not be obligated to deliver any of the
Shares to be delivered on the First Delivery Date or the Second Delivery Date
(as defined in Section 4), as the case may be, except upon payment for all the
Shares to be purchased on such Delivery Date as provided herein.

                  3. OFFERING OF SHARES BY THE UNDERWRITERS.

                  Upon authorization by the Representatives of the release of
the Firm Shares, the several Underwriters propose to offer the Firm Shares for
sale upon the terms and conditions set forth in the Prospectus; PROVIDED,
HOWEVER, that no Shares registered pursuant to the Rule 462(b) Registration
Statement, if any, shall be offered prior to the Effective Time thereof.

                  It is understood that up to 820,000 Firm Shares ("Directed

accordance with the rules and regulations of the NASD to certain persons
designated by the Company ("Directed Sale Share Purchasers") who have heretofore
delivered to the Representatives offers to purchase Directed Sale Shares in form
satisfactory to the Representatives, and that any allocation of Directed Sale
Shares among the Directed Sale Share Purchasers shall be made in accordance with
timely directions received by the Representatives from

the Company; PROVIDED, HOWEVER, that under no circumstances shall the
Representatives or any Underwriter be liable to, or have any liability
whatsoever for, the Company or to any Directed Sale Share Purchaser for any
action taken or omitted in good faith in connection with such offering to the
Directed Sale Share Purchasers. It is further understood that any such Directed
Sale Shares which are not purchased by the Directed Sale Share Purchasers will
be offered by the Underwriters to the public upon the terms and conditions set
forth in the Prospectus.

                  4. DELIVERY OF AND PAYMENT FOR THE SHARES. Delivery of and
payment for the Firm Shares shall be made at the office of Simpson Thacher &
Bartlett, U.S. counsel to the Underwriters, located at 425 Lexington Avenue, New

to be delivered certificates representing the Firm Shares to the Representatives
for the account of each Underwriter against payment to or upon the order of the
Company of the purchase price by wire transfer in immediately available funds to
a bank account at a bank located in New York City designated by the Company in
writing at least one business day prior to the First Delivery Date. Time shall
be of the essence, and delivery at the time and place specified pursuant to this
Agreement is a further condition of the obligation of each Underwriter
hereunder. Upon delivery, the Firm Shares shall be registered in such names and
in such denominations as the Representatives shall request in writing not less
than two full business days prior to the First Delivery Date. For the purpose of
expediting the checking and packaging of the certificates for the Firm Shares,
the Company shall make the certificates representing the Firm Shares available

Agreement, the option granted in Section 2 may be exercised in whole or in part
from time to time by written notice being given to the Company by the
Representatives. Such notice shall set forth the aggregate number of Option
Shares as to which the option is being exercised, the names in which the Option
Shares are to be registered, the denominations in which the Option Shares are to
be issued and the date and time, as determined by the Representatives, when the
Option Shares are to be delivered; PROVIDED, HOWEVER, that this date and time
shall not be earlier than the First Delivery Date nor earlier than the second
business day after the date on which the option shall have been exercised nor
later than the fifth business day after the date on which the option shall have
been exercised. The date and time the Option Shares are delivered are sometimes
referred to as the "Second Delivery Date" and the First Delivery Date and the
Second Delivery Date are sometimes each referred to as a "Delivery Date".

                  Delivery of and payment for the Option Shares shall be made at
the place specified in the first paragraph of this Section 4 (or at such other
place as shall be determined by agreement between the Representatives and the

                  effect of which, in any such case described in clause (i) or
                  (ii), is, in the judgment of the Representatives, so material
                  and adverse as to make it impracticable or inadvisable to
                  proceed with the public offering or the delivery of the Shares
                  being delivered on such Delivery Date on the terms and in the

                  conditions on the financial markets in the United States shall
                  be such) as to make it, in the judgment of a majority in
                  interest of the several Underwriters, impracticable or
                  inadvisable to proceed with the public offering or delivery of
                  the Shares being delivered on such Delivery Date on the terms
                  and in the manner contemplated in the Prospectus.

                  Shares shall have been completed as contemplated in the
                  Prospectus, and the Company shall have duly filed with the
                  British Virgin Islands Registrar of Companies amendments to
                  its Memorandum and Articles of Association to appropriately
                  reflect such share split and other matters relating to the
                  Common Shares in form and substance reasonably satisfactory to

                  insofar as such loss, claim, damage, liability or action
                  arises out of, or is based upon, (i) any untrue statement or
                  alleged untrue statement of a material fact contained (A) in
                  any Preliminary Prospectus, either of the Registration
                  Statements or the Prospectus, or in any amendment or
                  supplement thereto, or (B) in any blue sky application or
                  other document prepared or executed by the Company (or based
                  upon any written information furnished by the Company)
                  specifically for the purpose of qualifying any or all of the
                  Shares under the securities laws of any state or other
                  jurisdiction (any such application, document or information
                  being hereinafter called a "Blue Sky Application"), (ii) the
                  omission or alleged omission to state in any Preliminary
                  Prospectus, either of the Registration Statements or the
                  Prospectus, or in any amendment or supplement thereto, or in
                  any Blue Sky Application any material fact required to be
                  stated therein or necessary to make the statements therein not
                  misleading or (iii) any act or failure to act, or any alleged
                  act or failure to act, by any Underwriter in connection with,
                  or relating in any manner to, the Shares or the offering
                  contemplated hereby, and which is included as part of or
                  referred to in any loss, claim, damage, liability or action
                  arising out of or based upon matters covered by clause (i) or
                  (ii) above (PROVIDED that the Company and the Significant
                  Subsidiaries shall not be liable in the case of any matter
                  covered by this clause (iii) to the extent that it is
                  determined in a final judgment by a court of competent
                  jurisdiction that such loss, claim, damage, liability or
                  action resulted directly from any such act or failure to act
                  undertaken or omitted to be taken by such Underwriter through
                  its gross negligence or wilful misconduct), and shall
                  reimburse each Underwriter and each such director, officer,
                  employee and controlling person promptly upon demand for any
                  legal or other expenses reasonably incurred by that
                  Underwriter, director, officer, employee or controlling person
                  in connection with investigating or defending or preparing to
                  defend against any such loss, claim, damage, liability or
                  action as such expenses are incurred; PROVIDED, HOWEVER, that
                  the Company and the Significant Subsidiaries shall not be
                  liable in any such case to the extent that any such loss,
                  claim, damage, liability or action arises out of, or is based
                  upon, any untrue statement or alleged untrue statement or
                  omission or alleged omission made in any Preliminary
                  Prospectus, the Registration Statement or the Prospectus, or
                  in any such amendment or supplement, or in any Blue Sky
                  Application in reliance upon and in conformity with the
                  written information furnished to the Company through the
                  Representatives by or on behalf of any Underwriter
                  specifically for inclusion therein and described in Section
                  8(e). The foregoing indemnity agreement is in addition to any
                  liability which the Company may

                                                                              40


                  otherwise have to any Underwriter or to any director, officer,
                  employee or controlling person of that Underwriter.

                           (b) Each Underwriter, severally and not jointly,
                  shall indemnify and hold harmless the Company, its directors
                  (including any person who, with his or her consent, is named
                  in either of the Registration Statements as about to become a
                  director of the Company), officers and employees and each
                  person, if any, who controls the Company within the meaning of
                  the Securities Act, from and against any loss, claim, damage
                  or liability, joint or several, or any action in respect
                  thereof, to which the Company or any such director, officer,
                  employee or controlling person may become subject, under the
                  Securities Act or otherwise, insofar as such loss, claim,
                  damage, liability or action arises out of, or is based upon,
                  (i) any untrue statement or alleged untrue statement of a
                  material fact contained (A) in any Preliminary Prospectus,
                  either of the Registration Statements or the Prospectus, or in
                  any amendment or supplement thereto, or (B) in any Blue Sky
                  Application or (ii) the omission or alleged omission to state
                  in any Preliminary Prospectus, either of the Registration
                  Statements or the Prospectus, or in any amendment or
                  supplement thereto, or in any Blue Sky Application any
                  material fact required to be stated therein or necessary to
                  make the statements therein not misleading, but in each case
                  only to the extent that the untrue statement or alleged untrue
                  statement or omission or alleged omission was made in reliance
                  upon and in conformity with the written information furnished
                  to the Company through the Representatives by or on behalf of
                  that Underwriter specifically for inclusion therein and
                  described in Section 8(e), and shall reimburse the Company and
                  any such director, officer, employee or controlling person for
                  any legal or other expenses reasonably incurred by the Company
                  or any such director, officer or controlling person in
                  connection with investigating or defending or preparing to
                  defend against any such loss, claim, damage, liability or
                  action as such expenses are incurred. The foregoing indemnity
                  agreement is in addition to any liability which any
                  Underwriter may otherwise have to the Company or any such
                  director, officer or controlling person.

                           (c) Promptly after receipt by an indemnified party
                  under this Section 8 of notice of any claim or the
                  commencement of any action, the indemnified party shall, if a
                  claim in respect thereof is to be made against the
                  indemnifying party under this Section 8, notify the
                  indemnifying party in writing of the claim or the commencement
                  of that action; PROVIDED, HOWEVER, that the failure to notify
                  the indemnifying party shall not relieve it from any liability
                  which it may have under this Section 8 except to the extent it
                  has been materially prejudiced by such failure and, PROVIDED
                  FURTHER, that the failure to notify the indemnifying party
                  shall not relieve it from any liability which it may have to
                  an indemnified party otherwise than under this Section 8. If
                  any such claim or action shall be brought against an
                  indemnified party, and it shall notify the indemnifying party
                  thereof, the indemnifying party shall be entitled to
                  participate therein and, to the extent that it wishes, jointly
                  with any other similarly notified indemnifying party, to
                  assume the defense thereof with

<PAGE>
                                                                              41


                  counsel satisfactory to the indemnified party. After notice
                  from the indemnifying party to the indemnified party of its
                  election to assume the defense of such claim or action, the
                  indemnifying party shall not be liable to the indemnified
                  party under this Section 8 for any legal or other expenses
                  subsequently incurred by the indemnified party in connection
                  with the defense thereof other than reasonable costs of
                  investigation; PROVIDED, HOWEVER, that the Representatives
                  shall have the right to employ counsel to represent jointly
                  the Representatives and those other Underwriters and their
                  respective directors, officers, employees and controlling
                  persons who may be subject to liability arising out of any
                  claim in respect of which indemnity may be sought by the
                  Underwriters against the Company or any Significant Subsidiary
                  under this Section 8 if, in the reasonable judgment of the
                  Representatives, it is advisable for the Representatives and
                  those Underwriters, directors, officers, employees and
                  controlling persons to be jointly represented by separate
                  counsel, and in that event the fees and expenses of such
                  separate counsel shall be paid by the Company and the
                  Significant Subsidiaries. No indemnifying party shall (i)
                  without the prior written consent of the indemnified parties
                  (which consent shall not be unreasonably withheld), settle or
                  compromise or consent to the entry of any judgment with
                  respect to any pending or threatened claim, action, suit or
                  proceeding in respect of which indemnification or contribution
                  may be sought hereunder (whether or not the indemnified
                  parties are actual or potential parties to such claim or
                  action) unless such settlement, compromise or consent includes
                  an unconditional release of each indemnified party from all
                  liability arising out of such claim, action, suit or
                  proceeding, or (ii) be liable for any settlement of any such
                  action effected without its written consent (which consent
                  shall not be unreasonably withheld), but if settled with its
                  written consent or if there be a final judgment of the
                  plaintiff in any such action, the indemnifying party agrees to
                  indemnify and hold harmless any indemnified party from and
                  against any loss of liability by reason of such settlement or
                  judgment.

                           (d) If the indemnification provided for in this
                  Section 8 shall for any reason be unavailable to or
                  insufficient to hold harmless an indemnified party under
                  Section 8(a) or 8(b) in respect of any loss, claim, damage or
                  liability, or any action in respect thereof, referred to
                  therein, then each indemnifying party shall, in lieu of
                  indemnifying such indemnified party, contribute to the amount
                  paid or payable by such indemnified party as a result of such
                  loss, claim, damage or liability, or action in respect
                  thereof, (i) in such proportion as shall be appropriate to
                  reflect the relative benefits received by the Company and the
                  Significant Subsidiaries on the one hand and the Underwriters
                  on the other from the offering of the Shares or (ii) if the
                  allocation provided by clause (i) above is not permitted by
                  applicable law, in such proportion as is appropriate to
                  reflect not only the relative benefits referred to in clause
                  (i) above but also the relative fault of the Company and the
                  Significant Subsidiaries on the one hand and the Underwriters
                  on the other with respect to the statements or omissions which
                  resulted in such loss, claim, damage or liability, or action
                  in respect thereof, as well as any other relevant equitable
                  considerations. The

<PAGE>
                                                                              42


                  relative benefits received by the Company and the Significant
                  Subsidiaries on the one hand and the Underwriters on the other
                  with respect to such offering shall be deemed to be in the
                  same proportion as the total net proceeds from the offering of
                  the Shares purchased under this Agreement (before deducting
                  expenses) received by the Company, on the one hand, and the
                  total underwriting discounts and commissions received by the
                  Underwriters with respect to the Shares purchased under this
                  Agreement, on the other hand, bear to the total gross proceeds
                  from the offering of the shares of the Shares under this
                  Agreement, in each case as set forth in the table on the cover
                  page of the Prospectus. The relative fault shall be determined
                  by reference to whether the untrue or alleged untrue statement
                  of a material fact or omission or alleged omission to state a
                  material fact relates to information supplied by the Company
                  or the Underwriters, the intent of the parties and their
                  relative knowledge, access to information and opportunity to
                  correct or prevent such statement or omission. For purposes of
                  the preceding two sentences, the net proceeds deemed to be
                  received by the Company shall be deemed to be also for the
                  benefit of the Significant Subsidiaries and information
                  supplied by the Company shall also be deemed to have been
                  supplied by the Significant Subsidiaries. The Company, the
                  Significant Subsidiaries and the Underwriters agree that it
                  would not be just and equitable if contributions pursuant to
                  this Section 8(d) were to be determined by pro rata allocation
                  (even if the Underwriters were treated as one entity for such
                  purpose) or by any other method of allocation which does not
                  take into account the equitable considerations referred to
                  herein. The amount paid or payable by an indemnified party as
                  a result of the loss, claim, damage or liability, or action in
                  respect thereof, referred to above in this Section 8(d) shall
                  be deemed to include, for purposes of this Section 8(d), any
                  legal or other expenses reasonably incurred by such
                  indemnified party in connection with investigating or
                  defending any such action or claim. Notwithstanding the
                  provisions of this Section 8(d), no Underwriter shall be
                  required to contribute any amount in excess of the amount by
                  which the total price at which the Shares underwritten by it
                  and distributed to the public was offered to the public
                  exceeds the amount of any damages which such Underwriter has
                  otherwise paid or become liable to pay by reason of any untrue
                  or alleged untrue statement or omission or alleged omission.
                  No person guilty of fraudulent misrepresentation (within the
                  meaning of Section 11 (f) of the Securities Act) shall be
                  entitled to contribution from any person who was not guilty of
                  such fraudulent misrepresentation. The Underwriters'
                  obligations to contribute as provided in this Section 8(d) are
                  several in proportion to their respective underwriting
                  obligations and not joint.

                           (e) The Underwriters severally confirm, and the
                  Company acknowledges, that the statements with respect to the
                  public offering of the Shares set forth in the box on the
                  cover page of, and the selling concession and reallowance
                  figures under the caption "Underwriting" in, the Prospectus
                  are correct and constitute the only information furnished in
                  writing to the Company by or on behalf of the Underwriters
                  specifically for inclusion in the Registration Statements and
                  the Prospectus.

                                                                              43


                  9. DEFAULTING UNDERWRITERS. If, on either Delivery Date, any
Underwriter defaults in the performance of its obligations under this Agreement,
the remaining non-defaulting Underwriters shall be obligated severally to
purchase the Shares which the defaulting Underwriter agreed but failed to
purchase on such Delivery Date in the respective proportions which the number of
Firm Shares set opposite the name of each remaining non-defaulting Underwriter
in Schedule 1 hereto bears to the total number of Firm Shares set opposite the
names of all the remaining non-defaulting Underwriters in Schedule 1 hereto;
PROVIDED, HOWEVER, that the remaining non-defaulting Underwriters shall not be
obligated to purchase any of the Shares on such Delivery Date if the total
number of Shares which the defaulting Underwriter or Underwriters agreed but
failed to purchase on such date exceeds 9.09% of the total number of the Shares
to be purchased on such Delivery Date, and any remaining non-defaulting
Underwriter shall not be obligated to purchase more than 110% of the number of
Shares which it agreed to purchase on such Delivery Date pursuant to the terms
of Section 2. If the foregoing maximums are exceeded, the remaining
non-defaulting Underwriters, or those other underwriters satisfactory to the
Representatives who so agree, shall have the right, but shall not be obligated,
to purchase, in such proportion as may be agreed upon among them, all the Shares
to be purchased on such Delivery Date. If the remaining Underwriters or other
underwriters satisfactory to the Representatives do not elect to purchase the
shares which the defaulting Underwriter or Underwriters agreed but failed to
purchase on such Delivery Date, this Agreement (or, with respect to the Second
Delivery Date, the obligation of the Underwriters to purchase, and of the
Company to sell, the Option Shares) shall terminate without liability on the
part of any non-defaulting Underwriter or the Company, except that the Company
will continue to be liable for the payment of expenses to the extent set forth
in Sections 6 and 11. As used in this Agreement, the term "Underwriter"
includes, for all purposes of this Agreement unless the context requires
otherwise, any party not listed in Schedule 1 hereto who, pursuant to this
Section 9, purchases Firm Shares which a defaulting Underwriter agreed but
failed to purchase.

                  Nothing contained herein shall relieve a defaulting
Underwriter of any liability it may have to the Company for damages caused by
its default. If other underwriters are obligated or agree to purchase the Shares
of a defaulting or withdrawing Underwriter, either the Representatives or the
Company may postpone the First Delivery Date for up to seven full business days
in order to effect any changes that in the opinion of counsel for the Company or
counsel for the Underwriters may be necessary in the Registration Statement, the
Prospectus or in any other document or arrangement.

                  10. TERMINATION. The obligations of the Underwriters hereunder
may be terminated by the Representatives by notice given to and received by the
Company prior to delivery of and payment for the Firm Shares if, prior to that
time, any of the events described in Sections 7(m) or 7(n) shall have occurred
or if the Underwriters shall decline to purchase the Shares for any reason
permitted under this Agreement.

                  11. REIMBURSEMENT OF UNDERWRITERS' EXPENSES. If (a) the
Company shall fail to tender the Shares for delivery to the Underwriters for any
reason permitted under this Agreement, or (b) the Underwriters shall decline to

than U.S. dollars and as a result of any variation as between (i) the rate of
exchange at which the U.S. dollar amount is converted into the Judgment

such judgment or order as aforesaid. The term "spot rate of exchange" shall

                                      -4-

                  available for the payment of such dividends and whether or not
                  dividends are declared.

         (c)      Unless full cumulative dividends on all outstanding Class A
                  Preferred Shares and Class B Preferred Shares shall have been
                  declared and paid in full, then: (i) no dividend (other than a
                  dividend payable solely in shares of any Class A Junior
                  Securities or Class B Junior Securities) shall be declared or
                  paid upon, or any sum set apart for the payment of dividends

                  or Class B Junior Securities, other than a distribution

                  Securities or Class B Junior Securities shall be purchased,
                  redeemed or otherwise acquired or retired other than
                  securities received from an employee pursuant to a severance
                  agreement for value (excluding an exchange for shares of other
                  Class A Junior Securities or Class B Junior Securities) by the
                  Company or any of its Subsidiaries; and (iv) no monies shall
                  be paid into or set apart or made available for a sinking or
                  other like fund for the purchase, redemption or other
                  acquisition or retirement for value of any shares of Class A
                  Junior Securities or Class B Junior Securities by the Company
                  or any of its Subsidiaries.

         (d)      In the event that the Company declares and pays any dividends
                  upon the Common Shares (whether payable in cash, securities or
                  other property) other than dividends payable solely in Common
                  Shares, the Company shall also declare and pay to the holders
                  of the Preferred Shares at the same time it declares and pays
                  such dividends to the holders of the Common Shares, the
                  dividends which would have been declared and paid with respect
                  to the Common Shares issuable upon conversion of the Preferred
                  Shares had all of the issued and outstanding Preferred Shares
                  been converted immediately prior to the record date for such
                  dividend, or if no record date is fixed, the date as of which
                  the record holders of Common Shares entitled to such dividends
                  are to be determined.

         (3)      CONVERSION.

         (a)      A holder of Class A Preferred Shares may convert such shares,
                  in whole or in part, at the option of such holder into Common
                  Shares at any time after the date of issuance of such Class A
                  Preferred Shares in whole or in part at the option of such
                  holder. For the purposes of conversion, each Class A Preferred
                  Share shall be valued at the Class A Liquidation Preference,
                  which shall be divided by the Class A Conversion Price in
                  effect on the Conversion Date to



                                      -5-
<PAGE>

                  determine the number of Common Shares issuable for each Class
                  A Preferred Share upon conversion. Immediately following such
                  conversion, the rights of the holders of converted Class A
                  Preferred Shares shall cease and the Persons entitled to
                  receive the Common Shares upon the conversion of Class A
                  Preferred Shares shall be treated for all purposes as having
                  become the owners of such Common Shares.

                  A holder of Class B Preferred Shares may convert such shares,
                  in whole or in part, at the option of such holder, into Common
                  Shares at the Class B Conversion Price on or after the earlier
                  of (i) the six month anniversary of the effectiveness of a
                  registration statement of the Company filed with the United
                  States Securities and Exchange Commission in connection with
                  the registration of Common Shares, and (ii) February 15, 2001.
                  For the purposes of conversion, each Class B Preferred Share
                  shall be valued at the Class B Liquidation Preference, which
                  shall be divided by the Class B Conversion Price in effect on
                  the Conversion Date to determine the number of Common Shares
                  issuable for each Class B Preferred Share upon conversion.
                  Immediately following such conversion, the rights of the
                  holders of converted Class B Preferred Shares shall cease and
                  the Persons entitled to receive the Common Shares upon the
                  conversion of Class B Preferred Shares shall be treated for
                  all purposes as having become the owners of such Common
                  Shares.

         (b)      Upon the consummation of a Qualifying IPO, the outstanding
                  Class A Preferred Shares shall be automatically converted into
                  Common Shares at the Class A Conversion Price in effect
                  immediately after giving effect to the consummation of such
                  Qualifying IPO. Promptly following the occurrence of such
                  conversion, the Company shall give written notice thereof to
                  each record holder of converted Class A Preferred Shares,
                  including instructions to be followed to obtain a certificate
                  for the Common Shares into which such holder's Class A
                  Preferred Shares were converted.

                  Upon the six month anniversary of the consummation of a
                  Qualifying IPO, the outstanding Class B Preferred Shares shall
                  be automatically converted into Common Shares at the Class B
                  Conversion Price then in effect. Promptly following the
                  occurrence of such conversion, the Company shall give written
                  notice thereof to each record holder of converted Class B
                  Preferred Shares, including instructions to be followed to
                  obtain a certificate for the Common Shares into which such
                  holder's Class B Preferred Shares were converted.

         (c)      To convert Preferred Shares (other than an automatic
                  conversion pursuant to paragraph 3(b) above), a holder must
                  (i) surrender the certificate or certificates evidencing the
                  Preferred Shares to be converted, duly endorsed in a form
                  satisfactory to the Company, at the office of the Company or
                  transfer agent for



                                      -6-
<PAGE>

                  the Preferred Shares, (ii) notify the Company at such office
                  that he elects to convert Preferred Shares and the number of
                  shares to be converted and (iii) state in writing the name or
                  names in which he wishes the certificate or certificates for
                  Common Shares to be issued. The date on which the holder
                  satisfies all such requirements or the date on which the
                  Preferred Shares is automatically converted pursuant to
                  paragraph 3(b), as the case may be, shall be the "CONVERSION
                  DATE." As soon as practicable thereafter, the Company shall
                  deliver a certificate for the number of full Common Shares
                  issuable upon the conversion, except that the Company shall
                  not be required to deliver such certificate in the case of an
                  automatic conversion until the holders of the converted
                  Preferred Shares shall have complied with the provisions of
                  clauses (i) and (iii) of the first sentence of this paragraph
                  3(c). The Person in whose name the Common Shares certificate
                  is registered shall be treated as the shareholder of record on
                  and after the Conversion Date.

         (d)      The Company shall pay cash (based upon the Fair Market Value
                  of the Common Shares) in lieu of issuing any fractional Common
                  Shares upon conversion of Preferred Shares.

         (e)      If a holder converts Preferred Shares, the Company shall pay
                  any documentary, stamp or similar issue or transfer tax due on
                  the issue of Common Shares upon the conversion. However, the
                  holder shall pay any such tax that is due because the shares
                  are issued in a name other than the holder's name.

         (f)      The Company has reserved and shall continue to reserve out of
                  its authorized but unissued Common Shares or its Common Shares
                  held in treasury a sufficient number of Common Shares to
                  permit the conversion of the Preferred Shares in full. All
                  Common Shares that may be issued upon conversion of Preferred
                  Shares shall be fully paid and non-assessable. The Company
                  shall endeavor to comply with all securities laws regulating
                  the offer and delivery of Common Shares upon conversion of
                  Preferred Shares and if the Common Shares are then listed or
                  thereafter become listed on any national securities exchange
                  or automated quotation system, the Company shall use its best
                  efforts to list such shares on each such exchange or system on
                  which the Common Shares are or become listed, as the case may
                  be.

         (g)      If and whenever after the Class A Preferred Shares Issue Date
                  but prior to a Qualifying IPO, the Company shall issue or
                  sell, or is, in accordance with subparagraphs 3(g)(i) through
                  3(g)(viii) deemed to have issued or sold, any Common Shares
                  (other than options to acquire Common Shares under the
                  Company's share option plan and Common Shares issuable upon
                  the exercise of such options that are reserved for issuance as
                  of the Class A Preferred

                  Shares Issue Date), then, immediately upon such actual issue
                  or sale, or the date Common Shares are deemed to have been
                  issued or sold pursuant to subparagraphs 3(g)(i) through
                  3(g)(viii), the Class A Conversion Price shall be reduced to
                  (a) the price per share at which such Common Shares are sold,
                  in the case of a Strategic Sale, and (b) 75% of the price at
                  which the Common Shares are sold, in the case of any sale

                  provisions of this sentence result in an increase in the Class
                  A Conversion Price. On the date of a Qualifying IPO, the Class
                  A Conversion Price shall be the lower of (i) the Class A

                           issued.

                  (iv)     In case the Company shall declare, if any, a dividend
                           or make any other distribution upon any share of the

                  (v)      In the event the Company shall make or issue, or fix
                           a record date for the determination of holders of
                           Common Shares entitled to receive a dividend or other
                           distribution payable in securities of the Company,
                           then and in each such event lawful and adequate
                           provision shall be made so that the holders of Class

                           of such event and had they thereafter, during the
                           period from the date of such event to and including
                           the Conversion Date, retained such securities
                           receivable by them as aforesaid during such period,
                           giving application to all adjustments called for
                           during such period under this paragraph 3 with
                           respect to the rights of the holders of the Class A
                           Preferred Shares.

                  (vi)     In case any Common Shares, Options or Convertible
                           Securities shall be issued or sold for cash, the
                           consideration received therefor shall be deemed to be
                           the amount received by the Company therefor, without
                           deduction therefrom of any expenses incurred or any
                           underwriting commissions or concessions paid or
                           allowed by the Company in connection therewith. In
                           case any Common Shares, Options or Convertible
                           Securities shall be issued or sold for a
                           consideration other than cash, the amount of the
                           consideration other than cash received by the Company
                           shall be deemed to be the fair value of such
                           consideration as determined in good faith by the
                           Board of Directors, without deduction of any expenses
                           incurred or any underwriting commissions or
                           concessions paid or allowed by the Company in
                           connection therewith. In case any Options shall be
                           issued in connection with the issue and sale of other
                           securities of the Company, together comprising one
                           integral transaction in which no specific
                           consideration is allocated to such Options by the
                           parties thereto, such Options shall be deemed to have
                           been issued for such consideration of US$0.01.

                  (vii)    In case the Company shall fix a record date to
                           determine the holders of its Common Shares for the
                           purpose of entitling them (A) to receive a dividend
                           or other distribution payable in Common Shares,
                           Options or Convertible Securities or (B) to subscribe
                           for or purchase Common Shares, Options or Convertible
                           Securities, then such record date shall be deemed to
                           be the date of the issue or sale of Common Shares
                           deemed to have been issued or sold upon the
                           declaration of such dividend or the making of such
                           other distribution or the date of the granting of
                           such right of subscription or purchase, as the case
                           may be.

                  (viii)   The number of Common Shares issued and outstanding at
                           any given time shall not include shares owned or held
                           by or for the account of the Company (or any
                           Subsidiary), and the disposition of any Common Shares
                           so owned shall be considered an issue or sale of
                           Common Shares for the purpose of this subparagraph
                           3(g)(viii).

                  of the Class B Preferred Shares Issue Date), then, immediately
                  upon such actual issue or sale, or the date Common Shares are
                  deemed to have been issued or sold pursuant to subparagraphs
                  3(h)(i) through 3(h)(viii), the Class B Conversion Price shall
                  be reduced to (a) the price per share at which such Common
                  Shares are sold, in the case of a Strategic Sale, and (b) 75%
                  of the price at which the Common Shares are sold, in the case
                  of any sale (other than a Strategic Sale); provided, that only
                  reductions in the Class B Conversion Price shall be made
                  pursuant to this sentence and in no event shall the
                  application of the provisions of this sentence result in an
                  increase in the Class B Conversion Price. On the date of a
                  Qualifying IPO, the Class B Conversion Price shall be the

                           shall be made by reason of such issue or sale.

                           referred to in subparagraph 3(h)(i) or 3(h)(ii), or
                           the rate at which Convertible Securities referred to
                           in subparagraph 3(h)(i) or 3(h)(ii) are convertible
                           into or exchangeable for Common Shares shall change
                           at any time (including, but not limited to, changes

                           Options or Convertible Securities still outstanding
                           provided for such changed purchase price, additional
                           consideration or conversion rate, as the case may be,

                           Class B Conversion Price pursuant to this paragraph
                           3(h) that would increase the Class B Conversion Price
                           above the Class B Conversion Price in effect
                           immediately prior to the issuance of such Option or
                           Convertible Security; and on the expiration or
                           termination of any such Option or the termination of
                           any such right to convert or exchange such
                           Convertible Securities, the Class B Conversion Price
                           then in effect hereunder shall forthwith be increased
                           to the Class B Conversion Price which would have been
                           in effect at the time of such expiration or
                           termination had such Option or Convertible
                           Securities, to the extent outstanding immediately
                           prior to such expiration or termination, never been
                           issued.

                  (iv)     In case the Company shall declare, if any, a dividend
                           or make any other distribution upon any share of the
                           Company payable in Common Shares (except for
                           dividends or distributions upon the Common Shares
                           payable solely in Common Shares), Options or
                           Convertible Securities, any Common Shares, Options or
                           Convertible Securities, as the case may be, issuable
                           in payment of such dividend or distribution shall be
                           deemed to have been issued or sold without
                           consideration.

                  (v)      In the event the Company shall make or issue, or fix
                           a record date for the determination of holders of
                           Common Shares entitled to receive a dividend or other
                           distribution payable in securities of the Company,
                           then and in each such event lawful and adequate
                           provision shall be

                           shall receive upon conversion thereof in addition to
                           the number of Common Shares receivable thereupon, the
                           number of securities of the Company which they would
                           have received had their Class B Preferred Shares been
                           converted into Common Shares on the date of such
                           event and had they thereafter, during the period from
                           the date of such event to the date of a Qualifying
                           IPO, retained such securities receivable by them as
                           aforesaid during such period, giving application to
                           all adjustments called for during such period under
                           this paragraph 3 with respect to the rights of the
                           holders of the Class B Preferred Shares.

                  (vi)     In case any Common Shares, Options or Convertible
                           Securities shall be issued or sold for cash, the
                           consideration received therefor shall be deemed to be
                           the amount received by the Company therefor, without
                           deduction therefrom of any expenses incurred or any
                           underwriting commissions or concessions paid or
                           allowed by the Company in connection therewith. In
                           case any Common Shares, Options or Convertible
                           Securities shall be issued or sold for a
                           consideration other than cash, the amount of the
                           consideration other than cash received by the Company
                           shall be deemed to be the fair value of such
                           consideration as determined in good faith by the
                           Board of Directors, without deduction of any expenses
                           incurred or any underwriting commissions or
                           concessions paid or allowed by the Company in
                           connection therewith. In case any Options shall be
                           issued in connection with the issue and sale of other
                           securities of the Company, together comprising one
                           integral transaction in which no specific
                           consideration is allocated to such Options by the
                           parties thereto, such Options shall be deemed to have
                           been issued for such consideration of US$0.01.

                  (vii)    In case the Company shall fix a record date to
                           determine the holders of its Common Shares for the
                           purpose of entitling them (A) to receive a dividend
                           or other distribution payable in Common Shares,
                           Options or Convertible Securities or (B) to subscribe
                           for or purchase Common Shares, Options or Convertible
                           Securities, then such record date shall be deemed to
                           be the date of the issue or sale of Common Shares
                           deemed to have been issued or sold upon the
                           declaration of such dividend or the making of such
                           other distribution or the date of the granting of
                           such right of subscription or purchase, as the case
                           may be.

                  (viii)   The number of Common Shares issued and outstanding at
                           any given time shall not include shares owned or held
                           by or for the account of the

                           any Common Shares so owned shall be considered an
                           issue or sale of Common Shares for the purpose of
                           this subparagraph 3(h)(viii).

         (i)      In case the Company shall at any time divide (by any share
                  split, share dividend or otherwise) its outstanding Common
                  Shares into a greater number of shares, the Class A Conversion
                  Price and the Class B Conversion Price in effect immediately
                  prior to such division shall be proportionately reduced, and,
                  conversely in case the issued and outstanding Common Shares
                  shall be combined into a smaller number of shares, the Class A
                  Conversion Price and the Class B Conversion Price in effect
                  immediately prior to such combination shall be proportionately
                  increased.

         (j)      Except for an event which the holders of the Preferred Shares
                  elect to treat as a Liquidation in accordance with the
                  provisions of paragraph 4, if any capital reorganization or
                  reclassification of the shares of the Company, or a merger or
                  consolidation of the Company with or into another company or
                  the sale of all or substantially all of the Company's
                  properties and assets to any other Person, shall be effected
                  in such a way that holders of Common Shares shall be entitled
                  to receive shares, stock, securities or assets with respect to
                  or in exchange for Common Shares, then, as a condition of such
                  reorganization, reclassification, merger, consolidation or
                  sale, lawful and adequate provisions shall be made whereby
                  each holder of Preferred Shares shall thereupon have the right
                  to receive, upon the basis and upon the terms and conditions
                  specified herein and in lieu of Common Shares immediately
                  theretofore receivable upon the conversion of such Preferred
                  Shares, such shares, securities or assets as may be issued or
                  payable with respect to or in exchange for a number of
                  outstanding Common Shares equal to the number of such Common
                  Shares immediately theretofore receivable upon such conversion
                  had such reorganization, reclassification, merger,
                  consolidation or sale not taken place, and in any such case
                  appropriate provisions shall be made with respect to the
                  rights and interests of such holder to the end that the
                  provisions hereof (including without limitation provisions for
                  adjustments of the Conversion Price with respect to such
                  Preferred Shares) shall thereafter be applicable, as nearly as
                  may be, in relation to any shares, stock, securities or assets
                  thereafter deliverable upon the exercise of such conversion
                  rights.

         (k)      No adjustment in the Class A Conversion Price or Class B
                  Conversion Price need be made until all cumulative adjustments
                  amount to 1% or more of the Class A Conversion Price or Class
                  B Conversion Price, respectively, as last adjusted. Any
                  adjustments that are not made shall be carried forward and
                  taken into account in any subsequent adjustment. All
                  calculations under this paragraph 3 shall be made to the
                  nearest

                  1/10,000th of a cent or to the nearest 1/10,000th of a share,
                  as the case may be. No adjustment in the Class A Conversion
                  Price or Class B Conversion Price shall reduce the Class A
                  Conversion Price or Class B Conversion Price below the then
                  par value of the Common Shares.

         (l)      As used in this paragraph 3, the term "COMMON SHARES" shall
                  mean and include the Company's authorized Common Shares, par
                  value US$0.01 per share, as constituted on the date of filing
                  this instrument, and shall also include any shares of any
                  class of the Company thereafter authorized which shall not be
                  limited to a fixed sum or percentage of par value in respect
                  of the rights of the holders thereof to participate in
                  dividends or in the distribution of assets upon the voluntary
                  or involuntary liquidation, dissolution or winding up of the
                  Company; provided that the Common Shares receivable upon
                  conversion of Preferred Shares shall include only shares
                  designated as Common Shares of the Company on the date of
                  filing of this instrument, or in case of any reorganization or
                  reclassification of the outstanding shares thereof, the
                  shares, securities or assets provided for in paragraph 3(i).

         (m)      Whenever the Class A Conversion Price or the Class B
                  Conversion Price is adjusted, the Company shall promptly mail
                  to holders of Preferred Shares, first class, postage prepaid,
                  a notice of the adjustment. The Company shall file with the
                  transfer agent for the Class A Preferred Shares or Class B
                  Preferred Shares, as applicable, if any (and make available to
                  holders of Preferred Shares upon request), a certificate from
                  the Company's independent public accountants briefly stating
                  the facts requiring the adjustment and the manner of computing
                  it.

         (n)      In case at any time (i) the Company shall declare any dividend
                  upon its Common Shares payable in cash or shares or make any
                  other distribution to the holders of its Common Shares, (ii)
                  the Company shall offer for subscription pro rata to the
                  holders of its Common Shares any additional shares of any
                  class or other rights, (iii) there shall be any capital
                  reorganization or reclassification of the share capital of the
                  Company, or a consolidation or merger of the Company with or
                  into, or a sale of all or substantially all its assets to,
                  another Person or Persons or (iv) there shall be a voluntary
                  or involuntary dissolution, liquidation or winding up of the
                  Company, then, in any one or more of said cases, the Company
                  shall give, by first class mail, postage prepaid, or by
                  facsimile, addressed to each holder of any issued and
                  outstanding Preferred Shares at the address of such holder as
                  shown on the books of the Company, (A) at least 20 days' prior
                  written notice of the date on which the books of the Company
                  shall close or a record shall be taken for such dividend,
                  distribution or subscription rights or for determining rights
                  to vote in respect of any such reorganization,
                  reclassification,

                  consolidation, merger, sale, dissolution, liquidation or
                  winding up and (B) in the case of any such reorganization,
                  reclassification, consolidation, merger, sale, dissolution,
                  liquidation or winding up, at least 20 days' prior written
                  notice of the date when the same shall take place. Such notice
                  in accordance with the foregoing clause (A) shall also
                  specify, in the case of any such dividend, distribution or
                  subscription rights, the date on which the holders of Common
                  Shares shall be entitled thereto and such notice in accordance
                  with the foregoing clause (B) shall also specify the date or
                  projected date on which the holders of Common Shares shall be
                  entitled to exchange their Common Shares for securities or
                  other property deliverable upon such reorganization,
                  reclassification, consolidation, merger, sale, dissolution,
                  liquidation or winding up, as the case may be.

         (o)      The Company will at no time close its transfer books against
                  the transfer of any Preferred Shares or of any Common Shares
                  issued or issuable upon the conversion of any Preferred Shares
                  in any manner which interferes with the timely conversion of
                  such Preferred Shares, except as may otherwise be required to
                  comply with applicable securities laws.

         (4)      LIQUIDATION RIGHTS.

                  Upon any voluntary or involuntary liquidation, dissolution or
                  winding up of the Company resulting in a distribution of
                  assets to the holders of the Company's shares (each such
                  event, a "LIQUIDATION"), each holder of Class A Preferred
                  Shares will be entitled to payment out of the assets of the
                  Company available for distribution of an amount equal to the
                  Class A Liquidation Preference per Class A Preferred Share and
                  each holder of Class B Preferred Shares will be entitled to
                  payment out of the assets of the Company available for
                  distribution of an amount equal to the Class B Liquidation
                  Preference per Class B Preferred Share. Upon any Liquidation,
                  each holder of Class A Preferred Shares and each holder of
                  Class B Preferred Shares shall be entitled to payment out of
                  the assets of the Company available for distribution in full
                  up to the amount of the Class A Liquidation Preference per
                  Class A Preferred Share and the amount of the Class B
                  Liquidation Preference per Class B Preferred Share,
                  respectively, before any holder of any other series or class
                  of Preferred Shares or the Common Shares shall be entitled to
                  any payment out of the assets of the Company available for
                  distribution.

                  If, upon any Liquidation, the Class A Liquidation Preference
                  per Class A Preferred Share and the Class B Liquidation
                  Preference per Class B Preferred Share are not paid in full,
                  the holders of the issued and outstanding Class A Preferred
                  Shares and the holders of the issued and outstanding Class B
                  Preferred Shares will share equally and ratably in any
                  distribution of assets of



                                      -18-
<PAGE>

                  the Company in proportion to the full liquidation preference
                  and accumulated and unpaid dividends, to which each is
                  entitled.

                  For the purposes of this paragraph 4, holders of a majority of
                  the issued and outstanding Preferred Shares may designate that
                  a consolidation or merger of the Company (other than a merger
                  (i) in which the Company is the surviving company, (ii) which
                  involves only a change in the Company's state of
                  incorporation, or (iii) with a wholly-owned Subsidiary of the
                  Company) or the sale of all or substantially all of the
                  Company's assets shall be deemed to be a Liquidation with
                  respect to the Preferred Shares (each such event, an "ORGANIC
                  CHANGE"), if (A) the amount of consideration (including the
                  Fair Market Value of any non-cash consideration per share )
                  received would be less than the sum of the Class A Liquidation
                  Preference and the Class B Liquidation Preference, or (B) such
                  consideration consists solely or in part of securities that
                  are not readily marketable on a national exchange or on the
                  NASDAQ National Market System. In the event that the holders
                  of Preferred Shares shall deem any transaction to be a
                  "LIQUIDATION" in accordance with this paragraph 4, the holders
                  of the issued and outstanding Preferred Shares shall be
                  entitled to payment of the amount set forth in the first
                  paragraph of this paragraph 4. To the extent any consideration
                  consists of non-cash items, the consideration shall be the
                  Fair Market Value of such non-cash items.

         (5)      VOTING RIGHTS.

         (a)      The holders of the issued and outstanding Preferred Shares
                  shall have the right to vote, together with the holders of all
                  the issued and outstanding Common Shares and not by classes,
                  except as otherwise required by British Virgin Islands law or
                  the Articles of Association, on all matters on which holders
                  of Common Shares are entitled to vote. Each holder of
                  Preferred Shares shall have the right to cast one vote for
                  each whole Common Share which would be issued to such holder
                  upon conversion of such holder's Preferred Shares, assuming
                  that such conversion were to occur on the date immediately
                  prior to the record date for the determination of shareholders
                  entitled to vote.

         (b)      Subject to paragraph 13 hereof, the Company shall not, without
                  the affirmative vote or consent of the holders of at least a
                  majority of the Preferred Shares then issued and outstanding
                  (with shares held by the Company or any of its Affiliates not
                  being considered to be outstanding for this purpose) voting or
                  consenting, as the case may be, as one class:

                  (i)      amend or otherwise alter the Memorandum (including
                           the provisions of paragraph 5 hereof) in any manner
                           that adversely affects the



                                      -19-
<PAGE>

                           specified rights, preferences, privileges or voting
                           rights of holders of Preferred Shares;

                  (ii)     authorize the issuance of any additional Preferred
                           Shares;

                  (iii)    waive compliance with any provision of the
                           Memorandum; or

                  (iv)     declare or pay any dividend or distribution on any
                           Class A Junior Securities or Class B Junior
                           Securities.

         (6)      REDEMPTION.

         (a)      At the option and written election of any holder of issued and
                  outstanding Preferred Shares (a "REDEMPTION OPTION") given at
                  any time on or after five (5) years after the Class A
                  Preferred Shares Issue Date, the Company shall, subject to
                  applicable law, redeem all or any part of the issued and
                  outstanding Preferred Shares beneficially owned by such holder
                  at the price and upon the terms stated in this paragraph 6, at
                  any time on or after five (5) years after the Class A
                  Preferred Shares Issue Date.

         (b)      The Company shall redeem the Preferred Shares on the
                  Redemption Date (as such term is defined below), unless
                  otherwise prevented by law, at a cash redemption price per
                  share payable in a single installment equal to the Class A
                  Liquidation Preference, in the case of the Class A Preferred
                  Shares and the Class B Liquidation Preference, in the case of
                  the Class B Preferred Shares. The total sum payable per Class
                  A Preferred Share on the Redemption Date is hereinafter
                  referred to as the "CLASS A REDEMPTION PRICE," and the payment
                  to be made on the Redemption Date to the holders of the Class
                  A Preferred Shares is hereinafter referred to as the "CLASS A
                  REDEMPTION PAYMENT." The total sum payable per Class B
                  Preferred Share on the Redemption Date is hereinafter referred
                  to as the "CLASS B REDEMPTION PRICE," and the payment to be
                  made to the holders of the Class B Preferred Shares on the
                  Redemption Date is hereinafter referred to as the "CLASS B
                  REDEMPTION PAYMENT." The Class A Redemption Price and the
                  Class B Redemption Price are hereinafter referred to
                  collectively as the "REDEMPTION PRICES", and the Class A
                  Redemption Payment and the Class B Redemption Payment are
                  hereinafter referred to collectively as the "REDEMPTION
                  PAYMENTS."

         (c)      On and after the Redemption Date, all rights of any holder of
                  Preferred Shares, except the right to receive the applicable
                  Redemption Price per Preferred Share as hereinafter provided,
                  shall cease and terminate, and such Preferred Shares shall no
                  longer be deemed to be outstanding, whether or not the
                  certificates representing such shares have been received by
                  the Company;



                                      -20-
<PAGE>

                  provided, however, that, notwithstanding anything to the
                  contrary set forth herein, (i) if the Company defaults in the
                  payment of the applicable Redemption Payment, the rights of
                  the holders of the affected Preferred Shares with respect to
                  such Preferred Shares shall continue until the Company cures
                  such default, and (ii) without limiting any other rights of
                  such holders, upon the occurrence of (A) a subsequent
                  Liquidation or (B) an Organic Change, with respect to the
                  Preferred Shares in respect of which no Redemption Payment has
                  been received by a holder of Preferred Shares where the
                  Company had been required to make the payment, such holder
                  shall be accorded the rights and benefits set forth in
                  paragraph 4 hereof in respect of such shares, as if no prior
                  redemption request had been made.

         (d)      Within five (5) Business Days of receipt of a redemption
                  request by any holder of Preferred Shares, the Company shall
                  notify in writing all other holders of Preferred Shares of the
                  request for the redemption of Preferred Shares (the "COMPANY
                  NOTICE"). Each Company Notice shall state (i)
                  the Redemption Date, (ii) the number of Preferred Shares to be
                  redeemed, (iii) the Class A Redemption Price and Class B
                  Redemption Price, and the calculation thereof, (iv) the place
                  or places where certificates for such shares are to be
                  surrendered for payment of the applicable Redemption Price,
                  and (v) that dividends on the shares to be redeemed will cease
                  to accrue on such Redemption Date. On the date specified in
                  the Company Notice as the Redemption Date, which date shall be
                  no later than the 60th day following the date upon which the
                  Company shall have sent such Company Notice, the Company shall
                  pay each holder of Preferred Shares the applicable Redemption
                  Price, provided that the Company or its transfer agent has
                  received the certificates representing each Preferred Share to
                  be redeemed. Such payment date shall be referred to herein as
                  the "REDEMPTION DATE." If, on the Redemption
                  Date, less than all the Preferred Shares requested to be
                  redeemed may be legally redeemed by the Company, the
                  redemption of such Preferred Shares shall be made pro rata
                  based upon the total amount that would be paid by the Company
                  to each holder of Preferred Shares being redeemed if all of
                  the Preferred Shares requested to be redeemed by the holders
                  of Preferred Shares being redeemed were so redeemed, and any
                  Preferred Shares not redeemed shall be redeemed, at the
                  holder's election, on any date following the Redemption Date
                  on which the Company may lawfully redeem such shares. The
                  Company shall redeem (unless otherwise prevented by law) the
                  Preferred Shares being redeemed by each holder on the
                  Redemption Date, and the Company shall promptly advise each
                  such holder of Preferred Shares of the Redemption Date, or of
                  the relevant facts applicable thereto preventing such
                  redemption. Upon redemption of only a portion of the number of
                  shares covered by a Preferred Share certificate, the Company
                  shall issue and deliver



                                      -21-

                  to or upon the written order of the holder of such Preferred
                  Share certificate, at the expense of the Company, a new
                  certificate covering the number of Preferred Shares
                  representing the unredeemed portion of the Preferred Share
                  certificate, which new certificate shall entitle the holder
                  thereof to all the rights, powers, and privileges of a holder
                  of such shares.

                  In the event the Preferred Shares are not redeemed after a
                  Redemption Option is exercised, then, in addition to any other
                  remedies the holders of Preferred Shares may have, such
                  holders shall be entitled to elect a majority of the Members
                  of the Board of Directors, to serve until the redemption
                  obligations of the Company hereunder have been satisfied in
                  full.

         consent in writing of the majority of the issued shares of that class

10.      Subject to the provisions of these Articles and any resolution of
         Members, the unissued shares of the Company shall be at the disposal of
         the directors who may, without limiting or affecting any rights
         previously conferred on the holders of any existing shares or class or
         series of shares, offer, allot, grant options over or otherwise dispose
         of shares to such Persons, at such times and upon such terms and
         conditions as the Company may by Resolution of Directors determine.
11.      No share in the Company may be issued until the consideration in
         respect thereof is fully paid, and when issued the share is for all
         purposes fully paid and non-assessable save that a share issued for a
         promissory note or other written obligation for payment of a debt may
         be issued subject to forfeiture in the manner prescribed in these
         Articles.
12.      Shares in the Company shall be issued for money, services rendered,
         personal property, an estate in real property, a promissory note or
         other binding obligation to contribute money or property or any
         combination of the foregoing as shall be determined by a Resolution of
         Directors.
13.      Shares in the Company may be issued for such amount of consideration as
         the directors may from time to time by Resolution of Directors
         determine, except that in the case of shares with par value, the amount
         shall not be less than the par value, and in the absence of fraud the
         decision of the directors as to the value of the consideration received
         by the Company in respect of the issue is conclusive unless a question
         of law is involved. The consideration in respect of the shares




                                      -12-
<PAGE>

         constitutes capital to the extent of the par value and the excess
         constitutes surplus.
14.      A share issued by the Company upon conversion of, or in exchange for,
         another share or a debt obligation or other security in the Company,
         shall be treated for all purposes as having been issued for money equal
         to the consideration received or deemed to have been received by the
         Company in respect of the other share, debt obligation or security.
15.      Treasury shares may be disposed of by the Company on such terms and
         conditions (not otherwise inconsistent with these Articles) as the
         Company may by Resolution of Directors determine.
16.      The Company may issue fractions of a share and a fractional share shall
         have the same liabilities, limitations, preferences, privileges,
         qualifications, restrictions, rights and other attributes of a whole
         share of the same class or series of shares.
17.      Upon the issue by the Company of a share without par value, if an
         amount is stated in the Memorandum to be authorized capital represented
         by such shares then each share shall be issued for no less than the
         appropriate proportion of such amount which shall constitute capital,
         otherwise the consideration in respect of the share constitutes capital
         to the extent designated by the directors and the excess constitutes
         surplus, except that the directors must designate as capital an amount
         of the consideration that is at least equal to the amount that the
         share is entitled to as a preference, if any, in the assets of the
         Company upon liquidation of the Company.
18.      The Company may purchase, redeem or otherwise acquire and hold its own
         shares but only out of surplus or in exchange for newly issued shares
         of equal value.
19.      Subject to provisions to the contrary in
         (a)      the Memorandum or these Articles;
         (b)      the designations, powers, preferences, rights, qualifications,
                  limitations and restrictions with which the shares were
                  issued; or
         (c)      the subscription agreement for the issue of the shares,
         the Company may not purchase, redeem or otherwise acquire its own
         shares without the consent of Members whose shares are to be purchased,
         redeemed or otherwise acquired.
20.      No purchase, redemption or other acquisition of shares shall be made
         unless the directors determine that immediately after the purchase,
         redemption or other acquisition the Company will be able to satisfy its
         liabilities as they become due in the ordinary course of its business
         and the realizable value of the assets of the Company will not be less
         than the sum of its total liabilities, other than deferred taxes, as
         shown in the books of account, and its capital and, in the absence of
         fraud, the decision of the directors as to the realizable value of the
         assets of the Company is conclusive, unless a question of law is
         involved.

21.      A determination by the directors under the preceding Article is not
         required where shares are purchased, redeemed or otherwise acquired (a)
         pursuant to a right of a Member to have his shares redeemed or to have
         his shares exchanged for
                  money or other property of the Company;
         (b)      by virtue of a transfer of capital pursuant to Article 55;
         (c)      by virtue of the provisions of Section 83 of the Act; or
         (d)      pursuant to an order of the Court.
22.      Shares that the Company purchases, redeems or otherwise acquires
         pursuant to the preceding Article may be cancelled or held as treasury
         shares except to the extent that such shares are in excess of 80
         percent of the issued shares of the Company, in which case they shall
         be cancelled but they shall be available for reissue.
23.      Where shares in the Company are held by the Company as treasury shares
         or are held by another company of which the Company holds, directly or
         indirectly, shares having more than 50 percent of the votes in the
         election of directors of the other company, such shares of the Company
         are not entitled to vote or to have dividends paid thereon and shall
         not be treated as outstanding for any purpose except for purposes of
         determining the capital of the Company.
24.      The Company may purchase, redeem or otherwise acquire its shares at a
         price lower than the fair value if permitted by, and then only in
         accordance with, the terms of (a) the Memorandum or these Articles; or
         (b) a written agreement for the subscription for the shares to be
         purchased, redeemed or otherwise
                  acquired.
25.      The Company may by a Resolution of Directors include in the computation
         of surplus, for any purpose the unrealized appreciation of the assets
         of the Company and, in the absence of fraud, the decision of the
         directors as to the value of the assets is conclusive unless a question
         of law is involved.
                   MORTGAGES AND CHARGES OF REGISTERED SHARES
26.      Members may mortgage or charge their registered shares in the Company
         and upon satisfactory evidence thereof the Company shall give effect to
         the terms of any valid mortgage or charge except insofar as it may
         conflict with any requirements herein contained for consent to the
         transfer of shares.
27.      In the case of the mortgage or charge of registered shares there may be
         entered in the share register of the Company at the request of the
         registered holder of such shares (a) a statement that the shares are
         mortgaged or charged; (b) the name of the mortgagee or chargee, and (c)
         the date on which the aforesaid particulars are entered in the share
         register.

28.      Where particulars of a mortgage or charge are registered, such
         particulars shall be cancelled




                                      -14-
<PAGE>


         (a)      with the consent of the named mortgagee or chargee or anyone
                  authorized to act on his behalf; or
         (b)      upon evidence satisfactory to the directors of the discharge
                  of the liability secured by the mortgage or charge and the
                  issue of such indemnities as the directors shall consider
                  necessary or desirable.
29.      Whilst particulars of a mortgage or charge are registered, no transfer
         of any share comprised therein shall be effected without the written
         consent of the named mortgagee or chargee or anyone authorized to act
         on his behalf
                                   FORFEITURE
30.      When shares issued for a promissory note or other written obligation
         for payment of a debt have been issued subject to forfeiture, the
         following provisions shall apply.
31.      Written notice specifying a date for payment to be made and the shares
         in respect of which payment is to be made shall be served on the Member
         who defaults in making payment pursuant to a promissory note or other
         written obligations to pay a debt.
32.      The written notice specifying a date for payment shall
         (a)      name a further date not earlier than the expiration of 14 days
                  from the date of service of the notice on or before which
                  payment required by the notice is to be made; and
         (b)      contain a statement that in the event of non-payment at or
                  before the time named in the notice the shares, or any of
                  them, in respect of which payment is not made, will be liable
                  to be forfeited.
33.      Where a written notice has been issued and the requirements have not
         been complied with within the prescribed time, the directors may at any
         time before tender of payment forfeit and cancel the shares to which
         the notice relates.
34.      The Company is under no obligation to refund any moneys to the Member
         whose shares have been forfeited and cancelled pursuant to these
         provisions. Upon forfeiture and cancellation of the shares the Member
         is discharged from any further obligation to the Company with respect
         to the shares forfeited and cancelled. LIEN
35.      The Company shall have a first and paramount lien on every share issued
         for a promissory note or for any other binding obligation to contribute
         money or property or any combination thereof to the Company, and the
         Company shall also have a first and paramount lien on every share
         standing registered in the name of a Member, whether singly or jointly
         with any other Person or Persons, for all the debts and liabilities of
         such Member or his



                                      -15-
<PAGE>

         estate to the Company, whether the same shall have been incurred before
         or after notice to the Company of any interest of any Person other than
         such Member, and whether the time for the payment or discharge of the
         same shall have actually arrived or not, and notwithstanding that the
         same are joint debts or liabilities of such Member or his estate and
         any other Person, whether a Member of the Company or not. The Company's
         lien on a share shall extend to all dividends payable thereon. The
         directors may at any time either generally, or in any particular case,
         waive any lien that has arisen or declare any share to be wholly or in
         part exempt from the provisions of this Article.
36.      In the absence of express provisions regarding sale in the promissory
         note or other binding obligation to contribute money or property, the
         Company may sell, in such manner as the directors may by Resolution of
         Directors determine, any share on which the Company has a lien, but no
         sale shall be made unless some sum in respect of which the lien exists
         is presently payable nor until the expiration of twenty-one days after
         a notice in writing, stating and demanding payment of the sum presently
         payable and giving notice of the intention to sell in default of such
         payment, has been served on the holder for the time being of the share.
37.      The net proceeds of the sale by the Company of any shares on which it
         has a lien shall be applied in or towards payment of discharge of the
         promissory note or other binding obligation to contribute money or
         property or any combination thereof in respect of which the lien exists
         so far as the same is presently payable and any residue shall (subject
         to a like lien for debts or liabilities not presently payable as
         existed upon the share prior to the sale) be paid to the holder of the
         share immediately before such sale. For giving effect to any such sale
         the directors may authorize some Person to transfer the share sold to
         the purchaser thereof. The purchaser shall be registered as the holder
         of the share and he shall not be bound to see to the application of the
         purchase money, nor shall his title to the share be affected by any
         irregularity or invalidity in the proceedings in reference to the sale.

                               TRANSFER OF SHARES
38.      The El Sitio Shares held by any Member party to the Amended and
         Restated Shareholders Agreement dated as of November 9, 1999 (the
         "Shareholders Agreement") among the Company and the signatories thereto
         representing its Interest ("Covered Shares") shall not be transferable,
         directly or indirectly, except upon the conditions specified pursuant
         to Articles 38 to and including 47 hereof, which conditions are
         intended in part to ensure compliance with the provisions of the
         Securities Act in respect of any disposition of any Covered Shares or
         any interest therein which would constitute a sale thereof within the
         meaning of the Securities Act (a "Transfer"). As used in these
         Articles, the term "Transferor" refers to the transferor (whether by
         voluntary or involuntary means) of any Covered Shares, the term "Other
         Member" means the Member party to the Shareholders Agreement which is
         not the Transferor, and the term "Subject Shares" means the Covered
         Shares that have been or are to be Transferred.



                                      -16-

39.      In the event that an Involuntary Transfer (as hereinafter defined) by
         any Member party to the Shareholders Agreement of any Covered Shares
         may occur, the following procedures shall apply:

         (a)      The Member transferring the Covered Shares due to any
                  Involuntary Transfer shall promptly give written notice of
                  such Involuntary Transfer in reasonable detail to the Company
                  and to the Other Members, and the Person or Persons who take
                  or propose to take any interest in the Subject Shares as a
                  result of such Involuntary Transfer (the "Transferee") shall
                  hold such interest subject to the rights of the Other Members
                  as set forth below.
         (b)      Upon receipt of the notice referred to in paragraph (a) of
                  this Article 39 above or upon discovery of such Involuntary
                  Transfer, the Company shall cause the appraisal referred to in
                  paragraph (c) of this Article 39 to be made and each of the
                  Other Members shall have the irrevocable option, but not the
                  obligation, for a period of sixty (60) days following receipt
                  by all Other Members of the results of such appraisal, to
                  purchase the Subject Shares, subject to the terms set forth
                  herein. Each Other Member may exercise the option for the
                  number of Subject Shares which bears the same relation to the
                  total number of Subject Shares as (x) such Other Member's
                  Interest bears to (y) the aggregate Interest then held by all
                  of the Other Members exercising such option (and purchasing
                  Subject Shares under paragraph (c) of this Article 39 below),
                  or for such other number of Subject Shares as all of the Other
                  Members exercising such option may agree in writing. In the
                  event that the Other Members elect to purchase, in the
                  aggregate, less than all of the Subject Shares, then the Other
                  Members shall have no right to purchase any of the Subject
                  Shares.
         (c)      The closing for any such sale of Subject Shares to one or more
                  Other Members shall be at the offices of the Company on a
                  mutually satisfactory business day within fifteen (15) days
                  after the expiration of such sixty (60) day period. The
                  purchase price per share of any Subject Shares purchased
                  pursuant to this Article 39 shall be the amount which is equal
                  to the fair value, as of the Valuation Date (as hereinafter
                  defined), of a Subject Share, as such fair value is determined
                  by an independent appraiser selected by the Company and
                  reasonably acceptable to the Members holding, in the
                  aggregate, the majority of the aggregate Interests, and all
                  costs of any such appraisal shall be paid by the Company. The
                  "Valuation Date" shall be the last day of the calendar quarter
                  immediately preceding the Involuntary Transfer.

         (d)      The term "Involuntary Transfer" shall mean any involuntary
                  sale, transfer, encumbrance or other disposition by or in
                  which any Member shall transfer any Covered Shares, including,
                  without limitation, any



                                      -17-
<PAGE>

                  levy of execution, transfer in connection with bankruptcy,
                  judicial reorganization, insolvency or similar proceedings or
                  any transfer to a public officer or agency pursuant to any
                  abandoned property or escheat law; provided that any Transfer
                  complying with Articles 40, 41, 42 or 43 hereof shall not be
                  deemed to be an "Involuntary Transfer."

40.      RIGHTS OF FIRST OFFER. Except as otherwise expressly provided in
         Articles 41 and 42 hereof, no Member party to the Shareholders
         Agreement (other than the Class B Members) (such Member, the
         "Transferor") shall Transfer any Covered Shares, except in accordance
         with the following procedures:

         (a)      In the event that a Transferor wishes to Transfer any Covered
                  Shares and to the extent that any offers made pursuant to this
                  paragraph will not violate the Securities Act, the Transferor
                  shall first deliver to the Other Members a written notice (the
                  "Offer Notice"), which Offer Notice shall (i) specify the
                  terms, including the number of Covered Shares to be sold, and
                  the price per share at which the Transferor proposes to
                  Transfer such Covered Shares and (ii) be irrevocable for a
                  period of fifteen (15) days after delivery thereof, offering
                  (the "Offer") to the Other Members all of the Subject Shares
                  proposed to be sold by the Transferor at the purchase price
                  and on the terms specified therein. Each of the Other Members
                  shall have the right and option, at its sole discretion, for a
                  period of fifteen (15) days after delivery of the Offer Notice
                  (the "Acceptance Period"), to accept all, but not less than
                  all, of the Subject Shares (pro rata among such Other Members
                  so electing on the basis of the number of shares of El Sitio
                  Shares owned by such Other Members) offered at a price equal
                  to the purchase price and upon the other terms stated in the
                  Offer Notice. Such acceptance may be made by delivery of a
                  written notice to the Transferor within said fifteen (15) day
                  period, which notice shall specify whether such Member wishes
                  to purchase more than its pro rata share, if Other Members
                  decline to purchase, and if so, the maximum purchase such
                  Member elects to make. In the event that any Member elects not
                  to exercise its pro rata right to purchase, the Other
                  Member(s) shall have the right to purchase the Subject Shares
                  otherwise allocable to the non-participating Member pro rata
                  to their participation in the Offer, subject to the limits set
                  forth in the applicable Offer Notice. In the event that the
                  Other Members elect not to purchase all of the Subject Shares,
                  then the Other Members shall have no right to purchase all or
                  any portion of such Subject Shares and the Transferor shall be
                  free to Transfer the Subject Shares in accordance with
                  paragraph (c) of Article 40. A Member electing to purchase
                  Subject Shares pursuant to this Article 40 is referred to
                  herein as a "Purchasing Member". For purposes of this Article
                  40, if the Transferor is transferring Common Shares, then the
                  Class B Members shall be included as Other Members;



                                      -18-
<PAGE>

                  in all other cases, the Class B Members shall not be included
                  as Other Members.
         (b)      Notwithstanding anything to the contrary contained in Article
                  40 hereof, in the event the Transferor is one of the (i)
                  Initial Members, the other Initial Members will have a
                  priority right of first offer with respect to any Subject
                  Shares offered by an Initial Member, in accordance with the
                  terms and conditions of the Syndication Agreement among the
                  Initial Members and dated as of June 10, 1999, before any such
                  right may be exercised by any other Members or (ii) Preferred
                  Members, the other Preferred Members will have a priority
                  right of first offer with respect to any Preferred Shares
                  offered by a Preferred Member, before any such right may be
                  exercised by the other Members.
         (c)      Transfers, if any, of Subject Shares to the Purchasing Member
                  under the terms of this Article 40 shall be made at the
                  offices of the Company or any other address acceptable to the
                  Company on a mutually satisfactory business day within fifteen
                  (15) days after the expiration of the Acceptance Period. The
                  Transferor shall deliver the Subject Shares by delivering a
                  transfer of shares and the share certificates, if any, against
                  payment of the purchase price thereof, in accordance with the
                  terms of the Offer.
         (d)      If effective acceptance shall not be received pursuant to
                  paragraph (a) of Article 40 above, with respect to all Covered
                  Shares offered for sale pursuant to the Offer Notice, then the
                  Transferor may Transfer all or any part of the El Sitio Shares
                  so offered for sale at a price not less than the price, and on
                  terms not more advantageous to the purchaser than the terms
                  stated in the Offer Notice at any time within one hundred
                  eighty (180) days after the expiration of the Acceptance
                  Period.
         (e)      In the event that any Member exercises a purchase right under
                  paragraph (a) of this Article 40 and then fails to purchase
                  such shares in accordance with the terms of the Offer Notice
                  (each such Member, a "Defaulting Member"), then, in addition
                  to any remedies at law or in equity that the Transferor may
                  have in respect of such failure, the Defaulting Member shall
                  thereafter cease to have any right to receive offers or
                  purchase shares pursuant to paragraph (a) of this Article 40.
41.      EXEMPT TRANSFERS. Anything contained herein to the contrary
         notwithstanding, the provisions of Articles 40, 42 and 43 shall not be
         applicable to a Transfer (i) to an Affiliate of a Member or for the
         benefit of an Affiliate or a family member of a Member, if made solely
         for personal tax or estate planning purposes of the Transferor, or (ii)
         in an offering pursuant to the exercise of registration rights under
         the Amended and Restated Registration Rights Agreement made between the
         Company and the other signatories thereto, provided such Affiliate
         executes all documents (including the representation that such Transfer
         may be elected



                                      -19-

         without registration under the applicable provisions of the Securities
         Act and state securities or blue sky laws) deemed reasonably necessary
         by the Other Members to cause the Affiliate to become a party to, and
         be bound by, the terms of the Shareholders Agreement.

42.      TAG-ALONG RIGHTS.

         (a)      RIGHT TO PARTICIPATE IN SALE. Notwithstanding any other
                  provision hereof, if any Member party to the Shareholders
                  Agreement, other than any Class B Members (such Members,
                  together with their Affiliates, the "Selling Member(s)")
                  proposes to enter into an agreement with a third party to sell
                  or otherwise dispose of for value (such sale or other
                  disposition for value being referred to as a "Tag-Along Sale")
                  El Sitio Shares held by it to a third party who is not an
                  Affiliate (any such party, a "Third Party") pursuant to a bona
                  fide transaction (or series of related transactions) in which
                  shares representing an aggregate Interest of fifty percent
                  (50%) or more will be sold to a Third Party, then the Selling
                  Member(s) shall afford the other Member(s) party to the
                  Shareholders' Agreement (the "Tag-Along Member") the
                  opportunity to require that the sale by the Selling Member(s)
                  be conditioned upon such Third Party purchasing that number of
                  El Sitio Shares owned by such Tag-Along Member which delivers
                  a Tag-Along Notice in accordance with paragraph (c) of this
                  Article 42 equal to the product (rounded up to the nearest
                  whole number) of (i) the quotient determined by dividing (A)
                  the number of El Sitio Shares owned by such Tag-Along Member,
                  by (B) the number of El Sitio Shares owned by the Selling
                  Members and all Tag-Along Members which are selling El Sitio
                  Shares in the contemplated Tag-Along Sale, and (ii) the number
                  of El Sitio Shares proposed to be sold by all Members in the
                  contemplated Tag-Along Sale. In negotiating a Tag-Along Sale,
                  the Selling Member(s) shall provide (i) that the only
                  representations, warranties or covenants which any Tag-Along
                  Member shall be required to make in connection with any
                  Transfer are representations and warranties with respect to
                  its own ownership of the shares to be sold by it and its
                  ability to convey title thereto free and clear of liens,
                  encumbrances or adverse claims, its due organization, its due
                  authorization, execution and delivery of the definitive
                  purchase agreement (if applicable), enforceability of such
                  purchase agreement against it and no conflict of it with such
                  purchase agreement, and (ii) that the liability of the
                  Tag-Along Member with respect to any representation and
                  warranty made in connection with any Transfer is the several
                  liability of such Tag-Along Member (and not joint with any
                  other Person) and that such liability is limited to the amount
                  of proceeds actually received by such Tag-Along Member;
                  provided, however, that the foregoing shall not limit the
                  obligations of



                                      -20-
<PAGE>

                  such Tag-Along Member, and such Tag-Along Member hereby
                  expressly agrees to be bound by and be subject to, any escrow
                  or other holdback arrangement (on a pro rata basis based on
                  the number of shares sold by such Tag-Along Member in
                  proportion to all shares of the Company sold in such Tag-Along
                  Sale) provided for in the agreement relating to the Tag-Along
                  Sale. For purposes of this Article 42, if the Selling Member
                  is transferring Common Shares, then the Class B Members shall
                  be included as Tag-Along Members; in all other cases, the
                  Class B Members shall not be included as Tag-Along Members.
         (b)      SALE NOTICE. The Selling Member(s) shall provide each
                  Tag-Along Member and the Company with written notice (the
                  "Tag-Along Sale Notice") not less than thirty (30) days prior
                  to the proposed date of the Tag-Along Sale (the "Tag-Along
                  Sale Date"). Each Tag-Along Sale Notice shall be accompanied
                  by a copy of any agreement relating to the Tag-Along Sale (if
                  available) and shall set forth: (i) the name and address of
                  the Third Party in the Tag-Along Sale; (ii) the number of
                  Shares proposed to be Transferred by the Selling Member(s);
                  (iii) the proposed amount and form of consideration to be paid
                  for such shares expressed on a per share basis and the terms
                  and conditions of payment offered by the Third Party; (iv) the
                  aggregate number of shares of the Company held of record by
                  the Selling Member(s) as of the close of business on the day
                  immediately preceding the date of the Tag-Along Notice (the
                  "Tag-Along Notice Date"); (v) confirmation that the Third
                  Party has been informed of the "Tag-Along Rights" provided for
                  herein and has agreed to purchase shares from any Tag-Along
                  Member in accordance with the terms hereof; and (vi) the
                  Tag-Along Sale Date.

         (c)      TAG-ALONG NOTICE. Any Tag-Along Member wishing to participate
                  in the Tag-Along Sale shall provide written notice (the
                  "Tag-Along Notice") to the Selling Member(s) no less than
                  fifteen (15) days prior to the Tag-Along Sale Date. The
                  Tag-Along Notice shall set forth the number of El Sitio Shares
                  that such Tag-Along Member elects to include in the Tag-Along
                  Sale. The Tag-Along Notice given by any Tag-Along Member shall
                  constitute such Tag-Along Member's binding agreement to sell
                  the shares specified in the Tag-Along Notice on the terms and
                  conditions applicable to the Tag-Along Sale; provided,
                  however, that in the event that there is any material change
                  in the material terms and conditions of such Tag-Along Sale
                  applicable to the Tag-Along Member (including, but not limited
                  to, any decrease in the purchase price that occurs other than
                  pursuant to an adjustment mechanism set forth in the agreement
                  relating to the Tag-Along Sale) after such Tag-Along Member
                  gives its Tag-Along Notice, then, notwithstanding anything
                  herein to the contrary, the Tag-Along Member shall have the
                  right to



                                      -21-
<PAGE>

                  withdraw from participation in the Tag-Along Sale with respect
                  to all of its shares affected thereby. If the Third Party does
                  not consummate the purchase of all the shares requested to be
                  included in the Tag-Along Sale by any Tag-Along Member on
                  terms and conditions which are no more favorable in any
                  material respect to the Selling Member (except as otherwise
                  provided herein), then the Selling Member(s) shall not
                  consummate the Tag-Along Sale of any of its shares to the
                  Third Party. If a Tag-Along Notice from any Tag-Along Member
                  is not received by the Selling Member(s) prior to the fifteen
                  (15) day period specified above, the Selling Member(s) shall
                  have the right to consummate the Tag-Along Sale without the
                  participation of such Tag-Along Member, but only on terms and
                  conditions which are no more favorable in any material respect
                  to the Selling Member (and in any event, at no greater a
                  purchase price, except as the purchase price may be adjusted
                  pursuant to the agreement regarding the relevant sale or other
                  disposition) than as stated in the Tag-Along Sale Notice and
                  only if such Tag-Along Sale occurs on a date within one
                  hundred eighty (180) days of the Tag-Along Sale Date. If such
                  Tag-Along Sale does not occur within such one hundred eighty
                  (180) day period, the El Sitio Shares that were to be subject
                  to such Tag-Along Sale thereafter shall continue to be subject
                  to all of the restrictions contained in this Agreement.
         (d)      DELIVERY OF SHARES. On the Tag-Along Sale Date, each Tag-Along
                  Member shall deliver the shares to be sold in connection with
                  the Tag-Along Sale to the Third Party by delivering a transfer
                  of shares and the share certificates, if any, against delivery
                  of immediately available funds in the amount of the purchase
                  price for such shares.
         (e)      NO WAIVER. Any election in any instance by a Member not to
                  exercise its rights to participate in a Tag-Along Sale under
                  this Article 42 shall not constitute a waiver of such rights
                  with respect to any other proposed Transfer of shares of the
                  Company which would trigger such rights.
43.      DRAG-ALONG RIGHTS.

         (a)      GRANT OF DRAG-ALONG RIGHTS. If any Member party hereto, other
                  than any Class B Members (such Members, together with their
                  Affiliates, the "Selling Member(s)") proposes to enter into an
                  agreement with a third party to sell or otherwise dispose of
                  for value (such sale or other disposition for value being
                  referred to as a "Drag-Along Sale") El Sitio Shares held by it
                  to a third party who is not an Affiliate (any such party, a
                  "Third Party") pursuant to a bona fide transaction (or series
                  of related transactions) in which securities representing an
                  aggregate Interest of fifty percent (50%) or more will be sold
                  to a Third Party, then the remaining Member(s), other than the
                  Class B Members (the "Drag-Along Members") shall, upon the
                  written request of the Selling



                                      -22-
<PAGE>

                  Member(s), sell to such Third Party (i) El Sitio Shares owned
                  by such Drag-Along Member equal to (A) the number of El Sitio
                  Shares owned by such Drag-Along Member multiplied by (B) a
                  fraction ("Drag-Along Fraction"), the numerator of which is
                  the number of El Sitio Shares the Selling Member(s) intend to
                  sell pursuant to this Article 43 and the denominator of which
                  is the aggregate number of El Sitio Shares owned by the
                  Selling Member(s), and (ii) warrants owned by such Drag-Along
                  Member representing the right to acquire a number of shares
                  equal to (A) the number of shares underlying such Drag-Along
                  Members warrants multiplied by (B) the Drag-Along Fraction,
                  contemporaneously with the sale of such El Sitio Shares by the
                  Selling Member(s), for, with respect to the El Sitio Shares,
                  the same consideration and on the same terms as those provided
                  by such Third Party to the Selling Member(s) and, with respect
                  to the warrants, for the same consideration and on the same
                  terms as those provided by such Third Party to the Selling
                  Member(s) less the aggregate exercise price for the warrants
                  so transferred.
         (a)      EXERCISE OF DRAG-ALONG RIGHT. The Drag-Along Right shall be
                  exercisable by written notice given by the Selling Member(s)
                  to each Drag-Along Member, containing the price and other
                  material terms of the proposed sale and the date of the
                  closing of the proposed sale (the "Drag-Along Sale Date"),
                  which date shall not be less than twenty (20) nor more than
                  sixty (60) calendar days after the date of such notice.
         (b)      DELIVERY OF SHARES. On the Drag-Along Sale Date, each
                  Drag-Along Member shall deliver the shares to be sold in
                  connection with the Drag-Along Sale to the Third Party by
                  delivering a transfer of shares and the share certificates, if
                  any, against delivery of immediately available funds in the
                  amount of the purchase price for such shares.

44.           TRANSFERS IN VIOLATION OF AGREEMENT. If any voluntary Transfer of
         El Sitio Shares is made or attempted contrary to the provisions of this
         Agreement (such Transfer, an "Unauthorized Transfer"), the Other
         Members shall have the right to purchase all or part of such El Sitio
         Shares from the Person entered on the share register as the holder of
         the shares at any time before or after the Transfer at a purchase price
         per share equal to (i) if any El Sitio Shares are listed for trading on
         NASDAQ or the Bolsa de Comercios de Buenos Aires, the lesser of (x)
         eighty percent (80%) of the thirty (30) day average closing price over
         the thirty-day period immediately preceding the date of the initial




                                      -23-
<PAGE>

         Transfer contrary to this Agreement, or (y) eighty percent (80%) of the
         thirty (30) day average closing price for the thirty days immediately
         preceding the date of exercise of the right granted to the Other
         Members herein, or (ii) if no El Sitio Shares are listed for trading on
         NASDAQ or the Bolsa de Comercios de Buenos Aires, the lesser of (x)
         eighty percent (80%) of the Fair Value at the time of the initial
         transfer that was contrary to these Articles, or (y) eighty percent
         (80%) of the Fair Value at the time of the Other Members' purchase of
         such El Sitio Shares. The term "Fair Value" shall mean the amount at
         which the El Sitio Shares would change hands between an independent,
         willing buyer and an independent, willing seller, each having
         reasonable knowledge of all relevant facts and neither being under any
         compulsion to act (considering, where applicable, the relative rights
         of all outstanding classes or series of shares but not discounting the
         value of such securities for illiquidity or because they represent a
         minority ownership position in the Company), which amount shall be
         determined by the Board of Directors in its reasonable discretion and
         in good faith.

45.      PREEMPTIVE RIGHTS.

         (a)      Except for the issuance of the Company's shares or other
                  securities (i) pursuant to a Qualifying IPO; (ii) comprising
                  Class B Preferred Shares, up to an aggregate of 1,888,889
                  Class B Preferred Shares; (iii) comprising additional shares
                  or option issuances to employees of the Company pursuant to
                  share option plans existing on the date of the issuance of the
                  Class A Preferred Shares including the number of shares
                  issuable thereunder as of such date (or amendments to such
                  plans or new plans if agreed to by the Members) or (iv) in
                  connection with acquisitions of businesses by the Company
                  approved by the Members, if the Company at any time after the
                  date of the issuance of the Class A Preferred Shares
                  authorizes the issuance or sale of any shares of the Company
                  or any securities of the Company containing options or rights
                  to acquire any shares (other than as a dividend on the
                  outstanding shares), the Company shall first offer to sell to
                  the Members on a pro rata basis, all of such shares or other
                  securities (the "Offered Shares").
         (b)      In order to exercise its purchase rights under this paragraph
                  (b), each Member must within twenty (20) business days after
                  receipt of written notice from the Company describing in
                  reasonable detail the share capital or securities being
                  offered, the purchase price thereof and the payment terms,
                  deliver a written notice to the Company describing its
                  election hereunder. Such election shall indicate the number of
                  Offered Shares that the Member in its sole discretion elects
                  to purchase, which may be all or any portion of the Offered
                  Shares. The Company shall give the Members no less than
                  fifteen (15) business days notice of the closing of the sale
                  and purchase of such shares.
(c)               Upon the expiration of the 20-day period described above, the
                  Company shall be entitled to sell such shares or securities
                  which the Member has not elected to purchase during the ninety
                  (90) days following such expiration on terms and conditions,
                  including price, no more favorable

                  to the purchasers thereof than those offered to the Members.
                  Any shares or securities offered or sold by the Company to any
                  Person after such 90-day period must be re-offered to the
                  Members pursuant to the terms of this Article 45.
46.      The Company shall not be required to treat a transferee of a registered
         share in the Company as a Member until the transferee's name has been
         entered in the share register.

47.      Subject to any limitations in the Memorandum and these Articles, the
         Company must on the application of the transferor or transferee of a
         registered share in the Company enter in the share register the name of
         the transferee of the share save that the registration of transfers may
         be suspended and the share register closed at such times and for such
         periods as the Company may from time to time by Resolution of Directors
         determine provided always that such registration shall not be suspended
         and the share register closed for more than 60 days in any period of 12
         months.

                             TRANSMISSION OF SHARES
48.      The executor or administrator of a deceased Member, the guardian of an
         incompetent Member or the trustee of a bankrupt Member shall be the
         only Person recognized by the Company as having any title to his share
         but they shall not be entitled to exercise any rights as a Member of
         the Company until they have proceeded as set forth in the next
         following three Articles.

49.      The production to the Company of any document which is evidence of
         probate of the will, or letters of administration of the estate, or
         confirmation as executor, of a deceased Member or of the appointment of
         a guardian of an incompetent Member or the trustee of a bankrupt Member
         shall be accepted by the Company even if the deceased, incompetent or
         bankrupt Member is domiciled outside the British Virgin Islands if the
         document evidencing the grant of probate or letters of administration,
         confirmation as executed appointment as guardian or trustee in
         bankruptcy is issued by a foreign court which had competent
         jurisdiction in the matter. For the purpose of establishing whether or
         not a foreign court had competent jurisdiction in such a matter the
         directors may obtain appropriate legal advice. The directors may also
         require an indemnity to be given by the executor, administrator,
         guardian or trustee in bankruptcy.

50.      Any Person becoming entitled by operation of law or otherwise to a
         share or shares in consequence of the death, incompetence or bankruptcy
         of any Member may be registered as a Member upon such evidence being
         produced as may reasonably be required by the directors. An application
         by any such Person to be registered as a Member shall for all purposes
         be deemed to be a transfer of



                                      -25-
<PAGE>

         shares of the deceased, incompetent or bankrupt Member and the
         directors shall treat it as such.

51.      Any Person who has become entitled to a share or shares in consequence
         of the death, incompetence or bankruptcy of any Member may, instead of
         being registered himself, request in writing that some Person to be
         named by him be registered as the transferee of such share or shares
         and such request shall likewise be treated as if it were a transfer.

52.      What amounts to incompetence on the part of a person is a matter to be
         determined by the court having regard to all the relevant evidence and
         the circumstances of the case.

             REDUCTION OR INCREASE IN AUTHORIZED CAPITAL OR CAPITAL
53.      The Company may by a resolution of Members only amend the Memorandum to
         increase or reduce its authorized capital and in connection therewith
         the Company may in respect of any unissued shares increase or reduce
         the number of such shares, increase or reduce the par value of any such
         shares or effect any combination of the foregoing.

54.      Subject to the provisions relating to Members Reserved Matters, the
         Company may amend the Memorandum to

         (a)      divide the shares, including issued shares, of a class or
                  series into a larger number of shares of the same class or
                  series; or
         (b)      combine the shares, including issued shares, of a class or
                  series into a smaller number of shares of the same class or
                  series, provided, however, that where shares are divided or
                  combined under (a) or (b) of this Article, the aggregate par
                  value of the new shares must be equal to the aggregate par
                  value of the original shares.
55.      The capital of the Company may by a Resolution of Directors be
         increased by transferring an amount of the surplus of the Company to
         capital.

56.      Subject to the provisions of the two next succeeding Articles, the
         capital of the Company may by Resolution of Directors be reduced by
         transferring an amount of the capital of the Company to surplus.

57.      No reduction of capital shall be effected that reduces the capital of
         the Company to an amount that immediately after the reduction is less
         than the aggregate par value of all outstanding shares with par value
         and all shares with par value held by the Company as treasury shares
         and the aggregate of the amounts designated as capital of all
         outstanding shares without par



                                      -26-
<PAGE>

         value and all shares without par value held by the Company as treasury
         shares that are entitled to a preference, if any, in the assets of the
         Company upon liquidation of the Company.

58.      No reduction of capital shall be effected unless the directors
         determine that immediately after the reduction the Company will be able
         to satisfy its liabilities as they become due in the ordinary course of
         its business and that the realizable assets of the Company will not be
         less than its total liabilities, other than deferred taxes, as shown in
         the books of the Company and its remaining capital, and, in the absence
         of fraud, the decision of the directors as to the realizable value of
         the assets of the Company is conclusive, unless a question of law is
         involved.

                               MEETINGS OF MEMBERS
59.      The directors of the Company may convene such meetings of the Members
         of the Company at such times and in such manner and places within or
         outside the British Virgin Islands as the directors consider necessary
         or desirable.

60.      Upon the written request of Members holding 50 percent or more of the
         outstanding voting shares in the Company the directors shall convene a
         meeting of Members.

61.      The directors shall give not less than 10 days and not more than 60
         days prior written notice of meetings of Members to those Persons whose
         names on the date the notice is given appear as Members in the share
         register of the Company and are entitled to vote at the meeting. Except
         as otherwise required by law, notice of each meeting of Members,
         whether an annual meeting of Members or a special meeting of Members,
         shall state the purpose or purposes of the meeting, the place, date and
         hour of the meeting and, unless it is an annual meeting of Members,
         shall indicate that the notice is being issued by or at the direction
         of the Person or Persons calling the meeting.

62.      The directors may fix the date notice is given of a meeting of Members
         as the record date for determining those shares that are entitled to
         vote at the meeting.

63.      A meeting of Members may be called on short notice:

         (a)      if Members holding not less than 90 percent of the total
                  number of shares entitled to vote on all matters to be
                  considered at the meeting, or 90 percent of the votes of each
                  class or series of shares where Members are entitled to vote
                  thereon as a class or series together with not less than a 90
                  percent majority of the remaining votes, have agreed to short
                  notice of the meeting, or


                                      -27-
<PAGE>

         (b)      if all Members holding shares entitled to vote on all or any
                  matters to be considered at the meeting have waived notice of
                  the meeting and for this purpose presence at the meeting shall
                  be deemed to constitute waiver.

64.      The inadvertent failure of the directors to give notice of a meeting to
         a Member, or the fact that a Member has not received notice, does not
         invalidate the meeting.

65.      A Member may be represented at a meeting of Members by a proxy who may
         speak and vote on behalf of the Member.

66.      The instrument appointing a proxy shall be produced at the place
         appointed for the meeting before the time for holding the meeting at
         which the Person named in such instrument proposes to vote.

67.      An instrument appointing a proxy shall be in substantially the
         following form or such other form as the chairman of the meeting shall
         accept as properly evidencing the wishes of the Member appointing the
         proxy.

                                (Name of Company)
                  I/We _______________ being a member of the above Company with
         ______ shares HEREBY APPOINT _________________________________ of
         ________________ or failing him _________________ of _____________ to
         be my/our proxy to vote for me/us at the meeting of members to be held
         on the ___ day of ____________ and at any adjournment thereof. (Any
         restrictions on voting to be inserted here.) Signed this ___ day of
         ____________ Member
68. The following shall apply in respect of joint ownership of shares:

         (a)      if two or more Persons hold shares jointly each of them may be
                  present in Person or by proxy at a meeting of Members and may
                  speak as a Member;
         (b)      if only one of the joint owners is present in Person or by
                  proxy he may vote on behalf of all joint owners, and
         (c)      if two or more of the joint owners are present in or by proxy
                  they must vote as one.
69.      A Member shall be deemed to be present at a meeting of Members if he
         participates by telephone or other electronic means and all Members
         participating in the meeting are able to hear each other.

70.      Subject to Article 71 of these Articles, a meeting of Members is duly
         constituted if, at the commencement of the meeting, there are present
         in person or by proxy not less than 50 percent of the votes of the
         shares or class or series of shares



                                      -28-
<PAGE>

         entitled to vote on resolutions of Members to be considered at the
         meeting. If a quorum be present, notwithstanding the fact that such
         quorum may be represented by only one Person, then such Person may
         resolve any matter and a certificate signed by such Person accompanied
         where such Person be a proxy by a copy of the proxy form shall
         constitute a valid resolution of Members.



71.      With respect to any Members Reserved Matters, a meeting of Members is
         duly constituted if, at the commencement of the meeting, at which a
         quorum is present, there are present in person or by proxy each of the
         holders of the issued and outstanding El Sitio Shares. If a quorum be
         present, notwithstanding the fact that such quorum may be represented
         by only one Person, then such Person may resolve any matter and a
         certificate signed by such Person accompanied where such Person be a
         proxy by a copy of the proxy form shall constitute a valid resolution
         of Members. In case a quorum is not present at a meeting, the Members
         attending such meeting shall take any measures necessary to make such
         meeting ineffective, and thereby agree that any action taken at such
         meeting (other than such measures) shall be void ab initio.

72.      If within two hours from the time appointed for the meeting a quorum is
         not present, the meeting, if convened upon the requisition of Members,
         shall be dissolved; in any other case it shall stand adjourned to the
         next business day at the same time and place or to such other time and
         place as the directors may determine, and if at the adjourned meeting
         there are present within one hour from the time appointed for the
         meeting in person or by proxy not less than one third of the votes of
         the shares or each class or series of shares entitled to vote on the
         resolutions to be considered by the meeting, those present shall
         constitute a quorum but otherwise the meeting shall be dissolved.

73.      At every meeting of Members, the Chairman of the Board of Directors
         shall preside as chairman of the meeting. If there is no Chairman of
         the Board of Directors or if the Chairman of the Board of Directors is
         not present at the meeting, the Members present shall choose some one
         of their number to be the chairman. If the Members are unable to choose
         a chairman for any reason, then the Person representing the greatest
         number of voting shares present in person or by prescribed form of
         proxy at the meeting shall preside as chairman.



74.      The chairman may, with the consent of the meeting, adjourn any meeting
         from time to time, and from place to place, but no business shall be
         transacted at any



                                      -29-
<PAGE>

         adjourned meeting other than the business left unfinished at the
         meeting from which the adjournment took place.

75.      At any meeting of the Members the chairman shall be responsible for
         deciding in such manner as he shall consider appropriate whether any
         resolution has been carried or not and the result of his decision shall
         be announced to the meeting and recorded in the minutes thereof. If the
         chairman shall have any doubt as to the outcome of any resolution put
         to the vote, he shall cause a poll to be taken of all votes cast upon
         such resolution, but if the chairman shall fail to take a poll then any
         Member present in person or by proxy who disputes the announcement by
         the chairman of the result of any vote may immediately following such
         announcement demand that a poll be taken and the chairman shall
         thereupon cause a poll to be taken. If a poll is taken at any meeting,
         the result thereof shall be duly recorded in the minutes of that
         meeting by the chairman.

76.      Any Person other than an individual shall be regarded as one Member and
         subject to the specific provisions hereinafter contained for the
         appointment of representatives of such Persons the right of any
         individual to speak for or represent such Member shall be determined by
         the law of the jurisdiction where, and by the documents by which, the
         Person is constituted or derives its existence. In case of doubt, the
         directors may in good faith seek legal advice from any qualified Person
         and unless and until a court of competent jurisdiction shall otherwise
         rule, the directors may rely and act upon such advice without incurring
         any liability to any Member.

77.      Any Person other than an individual which is a Member of the Company
         may by resolution of its directors or other governing body authorize
         such Person as it thinks fit to act as its representative at any
         meeting of the Company or of any class of Members of the Company, and
         the Person so authorized shall be entitled to exercise the same powers
         on behalf of the Person which he represents as that Person could
         exercise if it were an individual Member of the Company.

78.      The chairman of any meeting at which a vote is cast by proxy or on
         behalf of any Person other than an individual may call for a notarially
         certified copy of such proxy or authority which shall be produced
         within 7 days of being so requested or the votes cast by such proxy or
         on behalf of such Person shall be disregarded.

79.      Directors of the Company may attend and speak at any meeting of Members
         of the Company and at any separate meeting of the holders of any class
         or series of shares in the Company.

80.      An action that may be taken by the Members at a meeting may also be
         taken by a resolution of Members consented to in writing or by telex,
         telegram, cable,



                                      -30-
<PAGE>

         facsimile or other written electronic communication, without the need
         for any notice, but if any resolution of Members is adopted otherwise
         than by the unanimous written consent of all Members, a copy of such
         resolution shall forthwith be sent to all Members not consenting to
         such resolution. The consent may be in the form of counterparts, each
         counterpart being signed by one or more Members.

                                    DIRECTORS
81.      The first directors of the Company shall be appointed by the
         subscribers to the Memorandum; and thereafter, the directors shall be
         elected by the Members as follows:

                  the Initial Shareholders shall have the right to elect four
                  (4) directors to the Board of Directors. The Class A Members

                  Preferred Director for so long as the Ibero Group shall own
                  one percent (1%) or more of El Sitio Shares on an as-converted
                  basis. If the Ibero Group owns less than one percent (1%) of
                  the El Sitio Shares on an as-converted basis, the Ibero Group
                  shall have the right to appoint an observer to the Board of

                  as Chestnut shall own (i) two and one-half percent (2.5%) or
                  more of its holdings of El Sitio Shares as of the date on
                  which El Sitio Shares were first issued to Chestnut on an
                  as-converted basis or (ii) one percent (1%) or more of El
                  Sitio Shares on an as-converted basis. If Chestnut owns less
                  than one percent (1%) of El Sitio Shares on an as-converted
                  basis, Chestnut shall have the right to appoint an observer to
                  the Board of Directors, who shall be entitled to participate
                  in the meetings of the Board of Directors, but shall not have

                  percent (2.5%) of its holdings of El Sitio Shares as of the

                  Sitio Shares on an as-converted basis. If IMPSAT owns less

                  basis,

                  IMPSAT shall have the right to appoint an observer to the
                  Board of Directors who shall be entitled to participate in the
                  meetings of the Board of Directors, but shall not have any
                  vote. The Class B Members shall have the right to appoint an
                  observer to the Board of Directors who shall be entitled to

                  will be nominated by the unanimous vote of all of the
                  directors of the Company and shall be independent to any other
                  holder of common shares or Class A Preferred Shares.

                  For the purpose of the foregoing provision the term "El Sitio
                  Shares" means, collectively, the Common Shares, the Preferred
                  Shares and any other class of shares of the Company issued at
                  any time which has the right to vote in all matters, each as

         (a)      If prior to his election to the Board of Directors, any
                  director-nominee shall be unwilling or unable to serve as a
                  director of the Company, the Member which nominated such
                  director shall be entitled to nominate a replacement who shall
                  then be the director-nominee for such Member for purposes of
                  the foregoing provision.
         (b)      The Common Members may, at any time and from time to time,
                  with or without cause, remove any Common Director by
                  resolution of the Common Members. A Common Director may not be
                  removed from office without cause without the prior written
                  consent of the Common Members. The Class A Members may, at any
                  time and from time to time, with or without cause remove any
                  Class A Director by resolution of the Class A Members. A Class
                  A Director may not be removed from office without cause
                  without the prior written consent of the Class A Members.
82.      The minimum number of directors shall be nine (9).

         members or until his earlier death, resignation or removal.

         resignation to the Company and the resignation shall have effect from
         the date the notice is received by the Company or from such later date
         as may be specified in the notice.

86.      Any vacancy of a Class A Director shall be filled by the Class A
         Members, and any vacancy of a Common Director shall be filled by the
         Common Members. A vacancy occurs through the death, resignation or
         removal of a director, but a vacancy or vacancies shall not be deemed
         to exist where one or more directors shall resign after having
         appointed his or their successor or successors.

87.      The Company may determine by Resolution of Directors to keep a register
         of directors containing

                  the Company;
         (b)      the date on which each person whose name is entered in the
                  register was appointed as a director of the Company; and
         (c)      the date on which each person named as director ceased to be a
                  director of the Company.
88.      If the directors determine to maintain a register of directors, a copy
         thereof shall be kept at the registered office of the Company and the

         capacity to the Company. On or before December 31 in each calendar year
         (beginning December 1, 1999), the Company shall pay to (i) the Ibero
         Group and Chestnut Hill (El Sitio), LLC a monitoring fee equal to
         $300,000 per annum in arrears (pro rated for any partial year), which
         shall be shared by them pro rata based on their respective interests in
         the Company, (ii) IMPSAT Corporation a monitoring fee equal to $100,000
         per annum in arrears (pro rated for any partial year), and (iii) Tower

         1% of the total capital of the Company. The Board of Directors shall
         have the right to review the compensation paid hereunder beginning at

         reduce, eliminate, maintain or increase all such fees.

90.      A director shall not require a share qualification.

<PAGE>

91.      Subject to the provisions of these Articles and any resolution of
         members, the business and affairs of the Company shall be managed by
         the directors who may pay all expenses incurred preliminary to and in
         connection with the formation and registration of the Company and may
         exercise all such powers of the Company as are not by the Act or by the
         Memorandum or these Articles required to be exercised by the Members of
         the Company or reserved for the approval of the majority of the Class A
         Directors, subject to any delegation of such powers as may be
         authorized by these Articles and to such requirements as may be
         prescribed by a resolution of Members; but no requirement made by a
         resolution of Members shall prevail if it be inconsistent with these
         Articles nor shall such requirement invalidate any prior act of the
         directors which would have been valid if such requirement had not been
         made.

92.      The directors may, by a Resolution of Directors, appoint any person,
         including a person who is a director, to be an officer or agent of the
         Company. The Resolution of Directors appointing an agent may authorize
         the agent to appoint one or more substitutes or delegates to exercise
         some or all of the powers conferred on the agent by the Company.

93.      Every officer or agent of the Company has such powers and authority of
         the directors, including the power and authority to affix the Seal, as
         are set forth in these Articles or in the Resolution of Directors
         appointing the officer or agent, except that no officer or agent has
         any power or authority with respect to the matters requiring a
         Resolution of Directors under the Act.

94.      Any director which is a body corporate may appoint any person its duly
         authorized representative for the purpose of representing it at
         meetings of the Board of Directors or with respect to unanimous written
         consents.

95.      The continuing directors may act notwithstanding any vacancy in their
         body, save that if their number is reduced to their knowledge below the
         number fixed by or pursuant to these Articles as the necessary quorum
         for a meeting of directors, the continuing directors or director may
         act only for the purpose of summoning a meeting of Members.

96.      Subject to the Provisions of the Memorandum and these Articles, the
         directors may by Resolution of Directors exercise all the powers of the
         Company to borrow money and to mortgage or charge its undertakings and
         property or any part thereof, to issue debentures, debenture stock and
         other securities whenever money is borrowed or as security for any
         debt, liability or obligation of the Company or of any third party.



                                      -34-

97.      All cheques, promissory notes, drafts, bills of exchange and other
         negotiable instruments and all receipts for moneys paid to the Company,
         shall be signed, drawn, accepted, endorsed or otherwise executed, as
         the case may be, in such manner as shall from time to time be
         determined by Resolution of Directors.

98.      The Company may determine by Resolution of Directors to maintain at its
         registered office a register of mortgages, charges and other
         encumbrances in which there shall be entered the following particulars
         regarding each mortgage, charge and other encumbrance:

         (a)      the sum secured;
         (b)      the assets secured;
         (c)      the name and address of the mortgagee, chargee or other
                  encumbrancer;
         (d)      the date of creation of the mortgage, charge or other
                  encumbrance; and
         (e)      the date on which the particulars specified above in respect
                  of the mortgage, charge or other encumbrance are entered in
                  the register.
99.      The Company may further determine by a Resolution of Directors to
         register a copy of the register of mortgages, charges or other
         encumbrances with the Registrar of Companies.

         PROCEEDINGS OF DIRECTORS
100.     The directors of the Company or any committee thereof may meet at such
         times and in such manner and places within or outside the British
         Virgin Islands as the directors may determine to be necessary or
         desirable, provided that a meeting of directors shall be held at least
         once in every quarter of each calendar year unless otherwise determined
         by a resolution of Members. Questions arising at any meeting shall be
         determined by the affirmative votes of a simple majority of directors
         present at such meeting, except for those matters which have been
         specifically reserved as Directors Reserved Matters.

101.     A director shall be deemed to be present at a meeting of directors if
         he participates by telephone or other electronic means and all
         directors participating in the meeting are able to hear each other.

102.     A director shall be given not less than 3 days notice of meetings of
         directors, but a meeting of directors held without 3 days notice having
         been given to all directors shall be valid if all the directors
         entitled to vote at the meeting who do not attend, waive notice of the
         meeting and for this purpose, the presence of a director at a meeting
         shall constitute waiver on his part. The inadvertent failure to give
         notice of a meeting to a director, or the fact that a director has not
         received the notice, does not invalidate the meeting.



                                      -35-
<PAGE>

103.     A director may by a written instrument appoint an alternate who need
         not be a director and an alternate is entitled to attend meetings in
         the absence of the director who appointed him and to vote or consent in
         place of the director.

104.     A meeting of directors is duly constituted for all purposes if at the
         commencement of the meeting there are present in person or by alternate
         not less than four (4) directors, except that with respect to those
         matters which have been specifically reserved as Directors Reserved
         Matters, a meeting of directors is duly constituted for all purposes if
         at the commencement of the meeting there are present in person or by
         alternate not less than four (4) directors including two (2) Class A
         Directors.

105.     At every meeting of the directors the Chairman of the Board of
         Directors shall preside as chairman of the meeting. If there is no
         Chairman of the Board of Directors or if the Chairman of the Board of
         Directors is not present at the meeting the Vice-Chairman of the Board
         of Directors shall preside. If there is no Vice-Chairman of the Board
         of Directors or if the Vice-Chairman of the Board of Directors is not
         present at the meeting the directors present shall choose some one of
         their number to be chairman of the meeting.

106.     An action that may be taken by the directors or a committee of
         directors at a meeting may also be taken by a Resolution of Directors
         or a committee of directors consented to in writing or by telex,
         telegram, cable, facsimile or other written electronic communication by
         all directors or all Members of the committee as the case may be,
         without the need for any notice. The consent may be in the form of
         counterparts, each counterpart being signed by one or more directors.

107.     The directors shall cause the following corporate records to kept:

         (a)      minutes of all meetings of directors, Members, committees of
                  directors, committees of officers and committees of Members;
         (b)      copies of all resolutions consented to by directors, Members,
                  committees of directors, committees of officers and committees
                  of Members; and
         (c)      such other accounts and records as the directors by Resolution
                  of Directors consider necessary or desirable in order to
                  reflect the financial position of the Company.
108.     The books, records and minutes shall be kept at the registered office
         of the Company, its principal place of business or at such other place
         as the directors determine.

109.     The directors, by Resolution of Directors, shall designate two
         permanently sitting committees, the Compensation Committee and the
         Audit Committee.



                                      -36-
<PAGE>

         Each committee shall consist of three Members, two representatives to
         be nominated by the Class A Members of which one shall be appointed by
         the Ibero Group and one by Chestnut, and the other representative to be
         nominated by the Initial Members.

110.     Each committee of directors has such powers and authorities of the
         directors, including the power and authority to affix the Seal, as are
         set forth in the Resolution of Directors establishing the committee,
         except that no committee has any power or authority to amend the
         Memorandum or these Articles, to appoint directors or fix their
         emoluments or to appoint officers or agents of the Company.

111.     The meetings and proceedings of each committee of directors consisting
         of three (3) or more directors shall be governed MUTATIS MUTANDIS by
         the provisions of those Articles regulating the proceedings of
         directors so far as the same are not superseded by any provisions in
         the resolution establishing the committee.

                                    OFFICERS
112.      The Company may by Resolution of Directors appoint officers of the
          Company at such times as shall be considered necessary or expedient.
          Such officers may consist of a Chairman of the Board of Directors, a
          Vice-Chairman of the Board of Directors, a President and one or more
          Vice-Presidents, Secretaries and Treasurer and such other officers as
          may from time to time be deemed desirable. Any number of offices may
          be held by the same person.

113.     The officers shall perform such duties as shall be prescribed at the
         time of their appointment subject to any modification in such duties as
         may be prescribed thereafter by Resolution of Directors or resolution
         of Members, but in the absence of any specific allocation of duties it
         shall be the responsibility of the Chairman of the Board of Directors
         to preside at meetings of directors and Member, the Vice-Chairman to
         act in the absence of the Chairman, the President to manage the day to
         day affairs of the Company, the Vice-Presidents to act in order of
         seniority in the absence of the President but otherwise to perform such
         duties as may be delegated to them by the President, the Secretaries to
         maintain the share register, minute books and records (other than
         financial records) of the Company and to ensure compliance with all
         procedural requirements imposed on the Company by applicable law, and
         the Treasurer to be responsible for the financial affairs of the
         Company.

114.     The emoluments of all officers shall be fixed by the Compensation
         Committee.

115.     The officers of the Company shall hold office until their successor are
         duly elected and qualified, but any officer elected or appointed by the
         directors may



                                      -37-
<PAGE>

         be removed at any time, with or without cause, by Resolution of
         Directors. Any vacancy occurring in any office of the Company may be
         filled by Resolution of Directors.

                              CONFLICT OF INTERESTS
116.     No Agreement or transaction between the Company and one or more of its
         directors or any Person in which any director has a financial interest
         or to whom any director is related, including as a director of that
         other Person, is void or voidable for this reason only or by reason
         only that the director is present at the meeting of directors or at the
         meeting of the committee of directors that approves the agreement or
         transaction or that the vote or consent of the director is counted for
         that purpose if the material facts of the interest of each director in
         the agreement or transaction are disclosed in good faith or are known
         by the other directors.

117.     A director who has an interest in any particular business to be
         considered at a meeting of directors or Members may be counted for the
         purposes of determining whether the meeting is duly constituted.

                                 INDEMNIFICATION
118.     Subject to the limitation hereinafter provided, the Company shall
         indemnify against all expenses, including legal fees, and against all
         judgments, fines and amounts paid in settlement and reasonably incurred
         in connection with legal, administrative or investigative proceeding
         against any Person who

         (a)      is or was a party or is threatened to be made a party to any
                  threatened, pending or completed proceedings, whether civil,
                  criminal, administrative or investigative, by reason of the
                  fact that the Person is or was a director, an officer or a
                  liquidator of the Company; or
         (b)      is or was, at the request of the Company, serving as a
                  director, officer or liquidator of, or in any other capacity
                  is or was acting for, another company or partnership, joint
                  venture, trust or other enterprise.
119.     The Company shall only indemnify a Person if the Person acted honestly
         and in good faith with a view to the best interests of the Company and,
         in the case of criminal proceedings, the Person had no reasonable cause
         to believe that his conduct was unlawful.

120.     The decision of the directors as to whether the Person acted honestly
         and in good faith and with a view to the best interests of the Company
         and as to whether the Person had no reasonable cause to believe that
         his conduct was unlawful is, in the absence of fraud, sufficient for
         the purposes of these Articles, unless a question of law is involved.



                                      -38-
<PAGE>

121.     The termination of any proceedings by any judgment, order, settlement,
         conviction or the entering of a nolle prosequi does not, by itself,
         create a presumption that the Person did not act honestly and in good
         faith and with a view to the best interests of the Company or that the
         Person had reasonable cause to believe that his conduct was unlawful.

122.     If a Person to be indemnified has been successful in defence of any
         proceedings referred to above the Person is entitled to be indemnified
         against all expenses, including legal fees, and against all judgments,
         fines and amounts paid in settlement and reasonable incurred by their
         Person in connection with the proceedings.

123.     The Company may purchase and maintain insurance in relation to any
         Person who is or was a director, an officer or a liquidator of the
         Company, or who at the request of the Company is or was serving as a
         director, an officer or a liquidator of, or in any other capacity is or
         was acting for, another company or a partnership, joint venture, trust
         or other enterprise, against any liability asserted against the Person
         and incurred by the Person in that capacity, whether or not the Company
         has or would have had the power to indemnify the Person against the
         liability as provided in the Articles.

                                      SEAL
124.     The Company may have more than one Seal and references herein to the
         Seal shall be references to every Seal which shall have been duly
         adopted by Resolution of Directors. The directors shall provide for the
         safe custody of the Seal and for an imprint thereof to be kept at the
         Registered Office. Except as otherwise expressly provided herein the
         Seal when affixed to any written instrument shall be witnessed and
         attested to by the signature of a director or any other Person so
         authorized from time to time by Resolution of Directors. Such
         authorization may be before or after the Seal is affixed, may be
         general or specific and may refer to any number of sealings. The
         Directors may provide for a facsimile of the Seal and of the signature
         of any director or authorized Person which may be reproduced by
         printing or other means on any instrument and it shall have the same
         force and validity as if the Seal had been affixed to such instrument
         and the same had been signed as hereinbefore described.

                                    DIVIDENDS
125.     The Company may by a Resolution of Directors declare and pay dividends
         in money, shares, or other property, but dividends shall only be
         declared and paid out of surplus. In the event that dividends are paid
         in specie the directors shall have responsibility for establishing and
         recording in the Resolution of Directors authorizing the dividends a
         fair and proper value for the assets to be so distributed.



                                      -39-

126.     The directors may from time to time pay to the Members such interim
         dividends as appear to the directors to be justified by the profits of
         the Company.

127.     The directors may, before declaring any dividend, set aside out of the
         profits of the Company such sum as they think proper as a reserve fund,
         and may invest the sum so set aside as a reserve fund upon such
         securities as they may select.

128.     No dividend shall be declared and paid unless the directors determine
         that immediately after the payment of the dividend the Company will be
         able to satisfy its liabilities as they become due in the ordinary
         course of its business and the realizable value of the assets of the
         Company will not be less than the sum of its total liabilities, other
         than deferred taxes, as shown in its books of account, and its capital.
         In the absence of fraud, the decision of the directors as to the
         realizable value of the assets of the Company is conclusive, unless a
         question of law is involved.

129.     Notice of any dividend that may have been declared shall be given to
         each Member in manner hereinaftermentioned and all dividends unclaimed
         for 3 years after having been declared may be forfeited by Resolution
         of Directors for the benefit of the Company.

130.     No dividend shall bear interest as against the Company and no dividend
         shall be paid on treasury shares or shares held by another company of
         which the Company holds, directly or indirectly, share having more than
         50 percent of the vote in electing directors.

131.     A share issued as a dividend by the Company shall be treated for all
         purposes as having been issued for money equal to the surplus that is
         transferred to capital upon the issue of the share.

132.     In the case of a dividend of authorized but unissued shares with par
         value, an amount equal to the aggregate par value of the shares shall
         be transferred from surplus to capital at the time of the distribution.

133.     In the case of a dividend of authorized but unissued shares without par
         value, the amount designated by the directors shall be transferred from
         surplus to capital at the time of the distribution, except that the
         directors must designate as capital an amount that is at least equal to
         the amount that the shares are entitled to as a preference, if any, in
         the assets of the Company upon liquidation of the Company.



                                      -40-

134.     A division of the issued and outstanding shares of a class or series of
         shares into a larger number of shares of the same class or series
         having a proportionately smaller par value does not constitute a
         dividend of shares.

                               ACCOUNTS AND AUDIT
135.     The Company may by resolution of Members call for the directors to
         prepare periodically a profit and loss account and a balance sheet. The
         profit and loss account and balance sheet shall be drawn up so as to
         give respectively a true and fair view of the profit and loss of the
         Company for the financial period and a true and fair view of the state
         of affairs of the Company as at the end of the financial period.

                  Members or in such manner as the Company may by resolution of
                  Members determine.
140.     The auditors shall examine each profit and loss account and balance
         sheet required to be served on every Member of the company or laid
         before a meeting of the Members of the Company and shall state in a
         written report whether or not

         (a)      in their opinion the profit and loss account and balance sheet
                  give a true and fair view respectively of the profit and loss
                  for the period covered by the accounts, and of the state of
                  affairs of the Company at the end of that period; and
         (b)      all the information and explanations required by the auditors
                  have been obtained.

         the rules of arbitration then in effect (the "ICC Rules") of the
         International Chamber of Commerce (the "ICC"). Any Member or Members
         electing to refer a matter to arbitration pursuant hereto (the
         "Petitioner") shall promptly deliver written notice (the "Arbitration
         Notice") to the other parties that it wishes to commence an arbitration
         proceeding. The Arbitration Notice shall set forth the matter being
         referred to arbitration and the name of the individual selected by the
         Petitioner as one of the arbitrators.

<PAGE>

148.     There shall be three (3) arbitrators, and each Member to the
         arbitration shall select one (1) arbitrator. Within twenty days of
         receipt of the Arbitration Notice, the other Member to such arbitration
         (the "Respondent") shall appoint an arbitrator (who shall have
         appropriate qualifications in relation to the matter in dispute) and
         notify the Petitioner of such appointment and submit its counter
         statement, if any, of the matter being referred to arbitration. If the
         Respondent fails to appoint an arbitrator within such twenty (20) day
         period, the Petitioner shall request the ICC President to appoint a
         second arbitrator who shall have appropriate qualifications in relation
         to the matter in dispute. Within twenty (20) days after appointment of
         the second arbitrator, the two arbitrators shall appoint the third
         arbitrator. If the two arbitrators fail to appoint the third arbitrator
         within such twenty (20) day period, either Member to the arbitration
         may request that the ICC President appoint the third arbitrator, who
         shall have appropriate qualifications in relation to the matter in
         dispute. All three (3) arbitrators shall be bilingual
         (Spanish/English). In the event that there are more than two (2)
         Members to such arbitration, all three (3) arbitrators shall be
         appointed by the ICC President.

149.     The arbitration proceedings shall be conducted in the English and
         Spanish languages in London, England, in accordance with the ICC Rules,
         and all documents in connection with any such proceedings shall be
         submitted in the English or Spanish languages or with a complete and
         accurate English or Spanish (as applicable) language translation. In
         any arbitration, the decision of the arbitrators shall be final and
         binding on the Members to the arbitration and judgment on the decision
         may be entered in and enforced in any court of competent jurisdiction
         in accordance with the New York Convention on the Recognition and
         Enforcement of Arbitral Awards. The substantially prevailing Member in
         such arbitration, in addition to all other relief provided, shall be
         entitled to an award of all of its reasonable costs and expenses
         including attorney fees and expenses and deposits and payments to the
         ICC.

150.     Each Member hereby agrees that each of the Members shall have the right
         to seek appropriate emergency or equitable relief to preserve the
         arbitral matter or to otherwise protect its rights pending resolution
         of the arbitral matter, whether in New York, New York, Argentina or in
         any other jurisdiction.

151.     The Members agree to negotiate in good faith to resolve any dispute
         involving the Class B Members regarding arising in connection with or
         relating in any way to the validity, construction, meaning,
         enforceability or performance of the Memorandum or Articles. If the
         negotiations do not resolve the dispute to the reasonable satisfaction
         of both parties to the dispute, then each such party shall nominate one
         senior officer of the rank of Vice President or higher as its




                                      -43-
<PAGE>

         representative. These representatives shall, within thirty (30) days of
         a written request by either party to call such a meeting, meet in
         person and alone (except for one assistant for each party) and shall
         attempt in good faith to resolve the dispute. If the disputes cannot be
         resolved by such senior managers in such meeting, the parties to the
         dispute shall, if requested in writing by either party, meet within
         thirty (30) days after such written notification for one day with an
         impartial mediator and consider dispute resolution alternatives other
         than litigation. If an alternative method of dispute resolution is not
         agreed upon within thirty (30) days after the one-day mediation, either
         party may begin litigation proceedings. This procedure shall be a
         prerequisite before taking any additional action hereunder.

                      VOLUNTARY WINDING UP AND DISSOLUTION
152.     The Company may voluntarily commence to wind up and dissolve by a
         resolution of Members but if the Company has never issued shares it may
         voluntarily commence to wind up and dissolve by resolution of director.

                                  CONTINUATION
153.     The Company may by resolution of Members or by a resolution passed
         unanimously by all directors of the Company continue as a company
         incorporated under the laws of a jurisdiction outside the British
         Virgin Islands in the manner provided under those laws.

         meeting (an "Annual Meeting") shall be held at least once every
         calendar year at such place, on such date, and at such time as the
         Board of Directors shall each year determine. The directors of the
         Company may convene such other meetings of the Members of the Company

                       EL SITIO INTERNATIONAL CORPORATION

                            STOCK PURCHASE AGREEMENT


                                 June 21, 1999

================================================================================
<PAGE>

            STOCK PURCHASE AGREEMENT, dated as of this 21st day of June, 1999
(this "Agreement"), among EL SITIO INTERNATIONAL CORPORATION, a corporation
organized and existing under the laws of the British Virgin Islands (the
"Company"), and each of the persons or entities set forth on Exhibit A (each, a
Purchaser).

                              W I T N E S S E T H:

            WHEREAS, the Company desires to issue to the Purchasers, and the
Purchasers desire to purchase from the Company, the Preferred Shares (as such
term is defined below) as set forth below; and

            WHEREAS, certain terms used in this Agreement are defined in Section
9.1 hereof;

            NOW, THEREFORE, in consideration of the promises and mutual
covenants and agreements hereinafter contained, the parties hereto hereby agree
as follows:

      1. Sale and Purchase of Securities.

            1.1 Sale and Purchase of Preferred Shares. Subject to the terms and
conditions of this Agreement, on the Closing Date (as defined in Section 3.1
hereof), the Company shall issue, sell and deliver to each of the Purchasers,
and each of the Purchasers shall purchase from the Company for the Purchase
Price (as defined in Section 2.1 hereof) that number of shares of Class A
Convertible Preferred Stock of the Company (the "Preferred Shares"), set forth
opposite such Purchaser's name on Exhibit A.

      2. Purchase Price.

            2.1 Amount of Purchase Price. The purchase price of the Preferred
Shares to be purchased pursuant to Section 1.1 by each Purchaser shall be as set
forth opposite such Purchaser's name on Exhibit A (the "Purchase Price"). The
Purchase Price shall be payable as provided in Section 2.2 hereof.

            2.2 Payment of the Purchase Price. At the Closing (as defined in
Section 3.1 hereof), each Purchaser shall pay its Purchase Price by wire
transfer of immediately available funds or by such other method as may be
reasonably acceptable to the Company and such Purchaser, to the account of the
Company as shall have been designated in advance to the Purchasers by the
Company.

            2.3 Barter. Washburn shall cause to be provided to the Company the
equivalent of Six Million Dollars ($6,000,000) in advertising time (the
"Advertising Time Credit") on any or all of the media networks owned or
controlled by Ibero-American Media Partners II Ltd. ("IAMP"), an Affiliate of
Washburn, in consideration for 853,994.06 Preferred Shares (the "Barter Shares")
purchased hereunder (at a purchase price of $7.02581 per share), subject to the
following terms and conditions:

            (a) For a period of 18 months from the Closing Date (the "Credit
Period"), the Company shall have the right to cause Washburn to cause the
Company's (or its Subsidiaries')


                                       2
<PAGE>

advertisements to be played on the media networks then owned or controlled by
IAMP in an amount necessary to exhaust the Advertising Time Credit. Schedule 2.3
sets forth a list of the media networks currently controlled by IAMP and other
media networks. In addition, in the event that the Company desires to run
advertisements on any media network not listed on Schedule 2.3 but with which
IAMP or its Affiliates have a business relationship (e.g., Univision), Washburn
agrees to use commercially reasonable efforts to place the Company's
advertisements on such other media network (but shall have no liability if
unable to do so), and if successful, the cost of such advertising may also be
charged against the Advertising Time Credit. It is the intent of the Company and
Washburn in entering into the agreements set forth in this Section 2.3 that
their relationship be governed by a spirit of good faith, fair dealing and
mutually beneficial usage of their respective assets. The usage of the
Advertising Time Credit will be determined by reference to the rate charged by
the applicable media network to other advertisers running advertisements during
the same programs, and the value of the advertising time actually used by the
Company and its Subsidiaries shall be deducted from the Advertising Time Credit.
Other than with regard to payment (for so long as there is any Advertising Time
Credit available), the Company shall be required to comply with any and all
requirements, procedures or standards (e.g., format, content restrictions,
scheduling, etc.) with which the applicable media network generally requires
other advertisers to comply. Each of the Company and Washburn agree to use
commercially reasonable efforts to establish a schedule for usage of the
Advertising Time Credit which meets their respective business objectives. At the
time advertisements are placed, the Company shall inform Washburn (or its
Affiliate) whether the cost of the advertising will be charged against the
Advertising Time Credit. In the event that at the end of the Credit Period, the
Barter Shares have been delivered to Washburn and the entire Advertising Time
Credit has not been used, any amount of the unused Advertising Time Credit (the
"Unused Credit") shall remain available to the Company to be used in the manner
contemplated by this paragraph for an additional six (6) month period.
Notwithstanding, the Company agrees to use commercially reasonable efforts to
utilize any Unused Credit as soon as is reasonably practicable following the end
of the Credit Period, and Washburn agrees that it shall use commercially
reasonable efforts to assist the Company in exhausting the Advertising Time
Credit during such six (6) month period.

            (b) Washburn (or one of its Affiliates) shall deliver to the Company
a statement of the cost of advertisements placed by the Company in each quarter
which will be charged against the Advertising Time Credit (the "Quarterly
Usage"), as promptly as practicable following the end of each calendar quarter
in which the Company places advertising. Within five (5) business days
thereafter, the Company shall issue, sell and deliver to Washburn that number of
the Barter Shares as is equal to the result of dividing the Quarterly Usage by
7.02581; provided, that in the event that there remain any Barter Shares which
have not been delivered to Washburn on the expiration of the Credit Period, the
Company shall, within five (5) business days following the expiration of the
Credit Period, deliver to the Company all remaining unissued Barter Shares. The
Barter Shares shall be, when delivered to Washburn, duly and irrevocably
authorized and validly issued, fully paid and non-assessable, regardless of
whether the Advertising Time Credit is fully used. In addition to any other
rights or remedies Washburn may have, Washburn shall be authorized to cease
providing any advertising to the Company in the event that the Barter Shares are
not delivered to Washburn when due.


                                       3

            (c) The Company and Washburn agree to discuss in good faith a
possible transfer of ownership of a building in Buenos Aires, Argentina located
at Avenida Melian No. 2752, 1430 Buenos Aires, Argentina from Washburn to the
Company. In the event that the transfer of ownership proceeds, the Company
agrees to assign and transfer all of its rights in respect of the lease of the
offices located at Avenida Ingeniero Huergo 1167/Azopardo 1168 (Puerto Madero)
to Imagen Satelital, S.A. The terms of such transfer are expected to include,
among others, a valuation based on an independent appraisal of the building's
value, a reasonably prompt closing date following agreement on terms, and shall
be conditioned upon the receipt of all necessary correspondent and governmental
permits and approvals for Imagen Satelital S.A. (an Affiliate of Washburn) to
relocate its facilities from the building. In the event that the parties proceed
with this transfer, the Company shall be permitted to apply up to $3 million of
the Advertising Time Credit against the purchase price of the building.

      3. Closing.

            3.1 Closing Date. The closing of the sale and purchase of the
Preferred Shares (the "Closing") shall take place at such place or places as the
parties shall mutually agree and is anticipated to occur on July 2, 1999, or at
such other time, date or place as the parties hereto may mutually agree;
provided that all conditions to the Closing set forth in this Agreement have
been satisfied or waived by such date. The date on which the Closing is held is
referred to in this Agreement as the "Closing Date." At the Closing, the parties
shall execute and deliver the documents referred to in Section 8 hereof.

      4. Representations and Warranties of the Company.

      The Company hereby represents and warrants to the Purchasers that:

            4.1 Organization and Good Standing; Capitalization.

            (a) The Company is duly organized and validly existing under the
laws of the British Virgin Islands and has the corporate power and authority to
own, lease and operate its properties and assets and to carry on its business as
now conducted and as it is proposed to be conducted, except where the lack
thereof would not have a Material Adverse Effect (as defined in Section 9). The
Company is duly qualified or authorized to do business as a foreign corporation
under the laws of each jurisdiction in which the conduct of its business or the
ownership of its properties or assets requires such qualification or
authorization except where the lack thereof would not have a Material Adverse
Effect.

            (b) The authorized and issued capital stock of the Company
immediately prior to and immediately after the Closing and the legal and
beneficial ownership thereof is as set forth on Schedule 4.1(b). All the
outstanding shares of capital stock of the Company have been duly authorized,
and are validly issued, fully paid and non-assessable. Except as disclosed on
Schedule 4.1(b), (i) there is no option, warrant, call, right, commitment or
other agreement of any character to which the Company is a party, (ii) there are
no securities of the Company outstanding which upon conversion or exchange would
require, and (iii) there are no stock appreciation rights, or other similar
rights based on securities of the Company which, in the case of clause (i), (ii)
or (iii), would require the issuance, sale or transfer of any additional shares
of


                                       4
<PAGE>

capital stock or other equity securities of the Company or other securities
convertible into, exchangeable for or evidencing the right to subscribe for or
purchase shares of capital stock or other equity securities of the Company.
Except as disclosed on Schedule 4.1(b) and other than this Agreement, the
Company is not a party to, nor is it aware of, any voting trust or other voting
agreement with respect to any of the securities of the Company or to any
agreement relating to the issuance, sale, redemption, transfer or other
disposition of the capital stock of the Company.

            4.2 Authorization of Agreement; Enforceability. The Company has all
requisite corporate power and authority to execute and deliver this Agreement
and each other agreement, document, instrument and certificate to be executed by
the Company in connection with the consummation of the transactions contemplated
by this Agreement (the "Transaction Documents"), and to perform fully its
obligations hereunder and thereunder. The execution, delivery and performance by
the Company of this Agreement and the Transaction Documents have been duly
authorized by all necessary corporate action on the part of the Company and its
stockholders. This Agreement and each of the Transaction Documents have been
duly and validly executed and delivered by the Company and, assuming the due
authorization, execution and delivery thereof by the Purchasers, this Agreement
and each of the Transaction Documents constitute the legal, valid and binding
obligations of the Company, enforceable against the Company in accordance with
their respective terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium and similar laws affecting creditors' rights and
remedies generally and subject, as to enforceability, to general principles of
equity (regardless of whether enforcement is sought in a proceeding at law or in
equity).

            4.3 Subsidiaries, Joint Ventures, Partnerships, Etc.

            (a) Schedule 4.3(a) hereof sets forth a true, complete and correct
list of each company or other entity in which the Company holds an interest of
greater than fifty percent (50%) (each such corporation or other entity is
referred to herein as a "Subsidiary" and, collectively, the "Subsidiaries").
Each Subsidiary is duly organized and validly existing in good standing (if
applicable) under the laws of the jurisdiction of its incorporation with
corporate power and corporate authority under such laws to own, lease and
operate its properties and conduct its business except, in each case, where the
lack thereof would not have a Material Adverse Effect; and each Subsidiary is
duly qualified to transact business as a foreign corporation and is in good
standing (if applicable) in each other jurisdiction in which it owns or leases
property of a nature, or transacts business of a type, that would make such
qualification necessary, except to the extent that the failure to so qualify or
be in good standing would not result in a Material Adverse Change. All of the
issued and outstanding shares of capital stock of each Subsidiary which are
owned by the Company have been duly authorized and validly issued, and are fully
paid and non-assessable. The Company, directly or indirectly, owns the
percentage of capital indicated in Schedule 4.3(a) next to each such Subsidiary,
free and clear of any Liens, except as set forth in Schedule 4.3(a).

            (b) The Company is not a party to any joint venture, partnership or
similar arrangement in which the Company or any of its Subsidiaries
participates.

            4.4 Consents of Third Parties. None of the execution and delivery by
the Company of this Agreement and the Transaction Documents, the consummation of
the


                                       5
<PAGE>

transactions contemplated hereby or thereby, or compliance by the Company with
any of the provisions hereof or thereof will (a) conflict with, or result in the
breach of, any provision of the articles or certificate of incorporation or
by-laws of the Company, (b) conflict with, violate, result in the breach or
termination of, or constitute a default or give rise to any right of termination
or acceleration or right to increase the obligations or otherwise modify the
terms thereof under any Permit or Order to which the Company is a party or any
Contract to which the Company or any of its Subsidiaries is bound or by which
the Company or any of its properties or assets is bound, (c) constitute a
violation of any Law applicable to the Company or (d) result in the creation of
any Lien upon the properties or assets of the Company. Except as set forth on
Schedule 4.4 and other than those which have been obtained or made, no consent,
waiver, approval, Order, Permit or authorization of, or declaration or filing
with, or notification to, any Person or Governmental Body is required on the
part of the Company in connection with the execution and delivery of this
Agreement or the Transaction Documents, or the compliance by the Company with
any of the provisions hereof or thereof.

            4.5 Authorization of Preferred Shares.

property.

            (b) Schedule 4.10(b) sets forth a complete list of all real property
and interests in real property leased by the Company or any of its Subsidiaries
(each, a "Real Property Lease",


                                       9
<PAGE>

and collectively, the "Real Property Leases") as lessee or lessor. The Company
or the applicable Subsidiary has good, legal and marketable title to the
leasehold estates in all Real Property Leases in each case free and clear of all
Liens. Neither the Company nor any Subsidiary has any reason to believe that
such title would not be insurable subject to customary exceptions.

            (c) Each of the Real Property Leases is valid and enforceable in
accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium and similar laws affecting creditors' rights and
remedies generally and subject, as to enforceability, to general principles of
equity (regardless of whether enforcement is sought in a proceeding at law or in
equity), and there is no default under any Real Property Lease by the Company or
the applicable Subsidiary or, to the knowledge of the Company, by any other
party thereto, and no event has occurred that with the lapse of time or the

modifications, supplements or side letters affecting the obligations of any
party thereunder.

            (d) No previous or current party to any Real Property Lease has
given notice of or made a claim with respect to any breach or default
thereunder. With respect to those Real Property Leases that were assigned or
subleased to the Company or a Subsidiary by a third party, all necessary
consents to such assignments or subleases have been obtained.

            4.11 Tangible Personal Property; Assets. Each of the Company and its
Subsidiaries has good, legal and marketable title to or valid leasehold
interests in, all of its personal property and assets. The personal property
owned by the Company or its Subsidiaries are held in each case free and clear of
all Liens, other than Permitted Liens. With respect to the personal property and
assets that the Company or any Subsidiary leases, the lessee thereunder is in
compliance with such leases except for such noncompliance as would not have a
Material Adverse Effect and the lessee holds a valid leasehold interest free and
clear of any Liens, other than Permitted Liens. All material items of personal
property and assets owned or leased by the Company and its Subsidiaries are in
good operating condition, normal wear and tear excepted.

            4.12 Intangible Property. Each of the Company and its Subsidiaries
owns or possesses adequate licenses or other rights to use all patents, patent
applications, trademarks, trademark applications, service marks, service mark
applications, trade names, copyrights, manufacturing processes, software,
formulae, trade secrets and know how (collectively, "Intellectual Property")
necessary to the conduct of its business as conducted; if any such Intellectual
Property necessary to the conduct of the business as proposed to be conducted is
not owned or licensed to the Company or to any of its Subsidiaries, such
Intellectual Property is readily available to the Company on commercially
reasonable terms, and no claim is pending or, to the knowledge of the Company,
threatened to the effect that the operations of the Company or any Subsidiary
infringe upon or conflict with the asserted rights of any other Person under any
Intellectual Property, and the Company does not know of any basis for any such
claim (whether or not pending or threatened). No claim is pending or, to the
knowledge of the Company, threatened to the effect that any such Intellectual
Property owned or licensed by the Company or any Subsidiary, or which the
Company or a Subsidiary otherwise has the right to use, is invalid or
unenforceable by the Company or the applicable Subsidiary, and the Company does
not know of any basis for any such claim (whether or not pending or threatened).
Neither the Company


                                       10

nor any Subsidiary has granted or assigned to any other Person any right to
provide the services or proposed services of the Company and its Subsidiaries.

(including the schedules and exhibits hereto) represents the entire
understanding and agreement among the parties hereto with respect to the subject
matter hereof and can be amended, supplemented or changed, and any provision
hereof can be waived, only by written instrument making specific reference to
this Agreement signed by the parties hereto. No action taken pursuant to this
Agreement, including without limitation, any investigation by or on behalf of
any party, shall be deemed to constitute a waiver by the party taking such
action of compliance with any representation, warranty, covenant or agreement
contained herein. The waiver by any party hereto of a breach of any provision of
this Agreement shall not operate or be construed as a further or continuing
waiver of such breach or as a waiver of any other or subsequent breach. No
failure on the part of any party to exercise, and no delay in exercising, any
right, power or remedy hereunder shall operate as a waiver thereof, nor shall
any single or partial exercise of such right, power or remedy by such party
preclude any other or further exercise thereof or the exercise of any other
right, power or remedy. All remedies hereunder are cumulative and are not
exclusive of any other remedies provided by law.

            9.7 Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York without giving effect to
the principles of conflict of laws thereunder which would specify the
application of the law of another jurisdiction.

            9.8 Headings; Interpretive Matters. The section headings of this
Agreement are for reference purposes only and are to be given no effect in the
construction or interpretation of this Agreement. No provision of this Agreement
will be interpreted in favor of, or against, any of the parties hereto by reason
of the extent to which any such party or its counsel participated in the
drafting thereof or by reason of the extent to which any such provision is
inconsistent with any prior draft hereof or thereof.

            9.9 Confidentiality. Each party hereto covenants and agrees to treat
any non-public information provided to it by the Company concerning the business
and finances of the Company ("Corporate Information") as confidential and agrees
further that it will not use, exploit, reproduce, disclose or provide Corporate
Information to any third party (other than any agents of the parties who are
bound by substantially similar obligations of confidentiality) on its own behalf
or otherwise, except with the consent of the Company or as required by law,
legal process or any federal or state regulatory body having jurisdiction over
such party. The provisions of this Section 9.9 shall not apply to any
information which:

            (a) was within the public domain prior to the time of disclosure of
Corporate Information to the receiving party or which comes into the public
domain other than as a result of a breach by the party of this Section 9.9;

            (b) was in the possession of the receiving party or any of its
officers, directors, employees, agents, principals, or Affiliates) before the
receiving party received the Corporate Information;

            (c) was rightfully acquired by the receiving party from a third
party without, to the knowledge of the receiving party, any restriction or any
obligation of confidentiality; or

            (d) was independently developed by the receiving party without any
use or reference to the Corporate Information.

            The provisions of this Section 9.9 shall survive the termination of
this Agreement, either in whole or as to any party, for a period of two (2)
years.

            9.10 Notices. All notices and other communications under this

unenforceable, the balance of this Agreement shall remain in effect.

            9.12 Binding Effect; Assignment. This Agreement shall be binding
upon and inure to the benefit of the parties and their respective successors and
permitted assigns. Nothing in this Agreement shall create or be deemed to create
any third-party beneficiary rights in any Person not a party to this Agreement
except as provided below. No assignment of this Agreement or of any rights or
obligations hereunder may be made by the Company or the Purchasers (by operation
of law or otherwise) without the prior written consent of the other parties
hereto and any attempted assignment without the required consents shall be void;
provided, however, that the Purchasers may assign this Agreement and any or all
rights and obligations hereunder, in whole or in part, to any Affiliate of the
Purchasers, but any such assignment shall not relieve the Purchasers of its
obligations hereunder. In addition, and whether or not any express assignment
has been made, the provisions of this Agreement which are for the benefit of the
Purchasers as a purchaser or holder of Preferred Shares (or any securities
pursuant to which such Preferred Shares may be converted or exercised into) are
also for the benefit of and enforceable by, any subsequent holder of such
Preferred Shares who acquires the lesser of (i) $5,000,000 in original purchase
price value of the Preferred Shares other than pursuant to open-market purchases
or (ii) fifty percent (50%) of the number of Preferred Shares purchased by the
Purchasers pursuant hereto. Upon any permitted assignment, the references in
this Agreement to the Purchasers shall also apply to any such assignee unless
the context otherwise requires.

            9.13 Counterparts. This Agreement may be executed simultaneously in
two or more counterparts, each of which shall be deemed an original but all of
which together shall constitute one and the same instrument.

1.    INTERNET DATA CENTER SERVICES.

Subject to the terms and conditions of this Agreement, during the term of this
Agreement, Exodus will provide to Customer the services described in the
Internet Data Center Services Order Form(s) ("IDC Services Order Form(s)")
accepted by Exodus, or substantially similar services if such substantially
similar services would provide Customer with substantially similar benefits
("Internet Data Center Services"). All IDC Services Order Forms accepted by
Exodus are incorporated herein by this reference, each as of the Submission Date
indicated in such form.

2.    FEES AND BILLING.

      2.1 Fees. Customer will pay all fees due according to the IDC Services
Order Form(s).

      2.2 Billing Commencement. Billing for Internet Data Center Services, other
than Setup Fees, indicated in the initial IDC Services Order Form shall commence
on the earlier to occur of (i) the "Installation Date" indicated on the initial
IDC Services Order Form, regardless of whether Customer has commenced use of the
Internet Data Services, unless Customer is unable to install the Customer
Equipment and/or use the Internet Data Center Services by the Installation Date
due to the fault of Exodus, then billing will not begin until the date Exodus
has remedied such fault and (ii) the date the "Customer Equipment" (Customer's
computer hardware and other tangible equipment, as identified in the Customer
Equipment List which is incorporated herein by this reference) is placed by
Customer in the "Customer Area" (the portion(s) of the Internet Data Centers, as
defined in Section 3.1 below, made available to Customer hereunder for the
placement of Customer Equipment) and is operational. All Setup Fees will be
billed upon receipt of a Customer signed IDC Services Order Form. In the event
that Customer orders additional Internet Data Center Services, billing for such
services shall commence on the date Exodus first provides such additional
Internet Data Center Services to Customer or as otherwise agreed to by Customer
and Exodus.

      2.3 Billing and Payment Terms. Customer will be billed monthly in advance
of the provision of Internet Data Center Services, and payment of such fees will
be due within thirty (30) days of the date of each Exodus invoice. All payments
will be made in U.S. dollars. Late payments hereunder will accrue interest at a
rate of one and one-half percent (1 1/2%) per month, or the highest rate allowed
by applicable law, whichever is lower. If in its judgment Exodus determines that
Customer is not creditworthy or is otherwise not financially secure, Exodus may,
upon written notice to Customer, modify the payment terms to require full
payment before the provision of Internet Date Center Services or other
assurances to secure Customer's payment obligation hereunder.

      2.4 Taxes. All payments required by this Agreement are exclusive of all
national, state, municipal or other governmental excise, sales, value-added,
use, personal property, and occupational taxes, excises, withholding taxes and
obligations and other levies now in force or enacted in the future, all of which
Customer will be responsible for and will pay in full, except for taxes based on
Exodus' net income.

3.    CUSTOMER'S OBLIGATIONS.

      3.1 Compliance with Law and Rules and Regulations. Customer agrees that
Customer will comply at all times with all applicable laws and regulations and
Exodus' general rules and regulations relating to its provision of Internet Data
Center Services, as updated by Exodus from time to time ("Rules and
Regulations"). Customer acknowledges that Exodus exercised no control whatsoever
over the content of the information passing through its sites containing the
Customer Area and equipment and facilities used by Exodus to provide Internet
Data Center Services ("Internet Data Centers"), and that it is the sole
responsibility of Customer to ensure that the information it transmits and
receives complies with all applicable laws and regulations.

      3.2 Customer's Costs. Customer agrees that it will be solely responsible,
and at Exodus's request will reimburse Exodus, for all costs and expenses (other
than those included as part of the Internet Data Center Services and except as
otherwise expressly provided herein) it incurs in connection with this
Agreement.

      3.3 Access and Security. Customer will be fully responsible for any
charges, costs, expenses (other than those included in the Internet Data Center
Services), and third party claims that may result form its use of, or access to,
the Internet Data Centers and/or the Customer Area including but not limited to
any unauthorized use of any access devices provided by Exodus hereunder. Except
with the advanced written consent of Exodus, Customer's access to the Internet
Data Centers will be limited solely to the individuals identified and authorized
by Customer to have access to the Internet Data Centers and the Customer Area in
accordance with this Agreement, as identified in the Customer Registration From,
as amended from time to time, which is hereby incorporated by this reference
("Representatives").

      3.4 No Competitive Services. Customer may not at any time permit any
Internet Data Center Services to be utilized for the provision of any services
that compete with any Exodus services, without Exodus' prior written consent.

      3.5 Insurance.

      (a) Minimum Levels. Customer will keep in full force and effect during the
term of this Agreement: (i) comprehensive general liability insurance in an
amount not less than $5 million per occurrence for bodily injury and property
damage; (ii) employer's liability insurance in an amount not less than $1
million per occurrence; and (iii) workers' compensation insurance in an amount
not less than that required by applicable law. Customer also agrees that it
will, and will be solely responsible for ensuring that its agents (including
contractors and subcontractors) maintain, other insurance at levels no less than
those required by applicable law and customer in Customer's and its agents'
industries.

      (b) Certificates of Insurance. Prior to installation of any Customer
Equipment in the Customer Area, Customer will furnish Exodus with certificates
of insurance which evidence the minimum levels of insurance set forth above.

      (c) Naming Exodus as an Additional Insured. Customer agrees that prior to
the installation of any Customer Equipment, Customer will cause its insurance
provider(s) to name Exodus as an additional insured and notify Exodus in writing
of the effective date thereof.

4.    CONFIDENTIAL INFORMATION

      4.1 Confidential Information. Each party acknowledges that it will have
access to certain confidential information of the other party concerning the
other party's business, plans, customers, technology, and products, including
the terms and conditions of this Agreement ("Confidential Information").
Confidential Information will include, but not be limited to, each party's
proprietary software and customer information. Each party agrees that it will
not use in any way, for its own account or the account of any third party,
except as expressly permitted by this Agreement, nor disclose to any third party
(except as required by law or to that party's attorneys, accountants and other
advisors as reasonably necessary), any of the other party's Confidential
Information and will take reasonable precautions to protect the confidentiality
of such information.

      4.2 Exceptions. Information will not be deemed Confidential Information
hereunder if such information: (i) is known to the receiving party prior to the
receipt from the disclosing party directly or indirectly from a source other
than one having an obligation of confidentiality to the disclosing party; (ii)
becomes known (independently of disclosure by the disclosing party) to the
receiving party directly or indirectly from a source other than one having an
obligation of confidentiality to the disclosing party; (iii) becomes publicly
known or otherwise ceases to be secret or confidential, except through a breach
of this Agreement by the receiving party; or (iv) is independently developed by
the receiving party.

5.    REPRESENTATIONS AND WARRANTIES.

      5.1 Warranties by Customer.

      (a) Customer Equipment. Customer represents and warrants that it owns or
has the legal right and authority, and will continue to own or maintain the
legal right and authority during the term of this Agreement, to place and use
the Customer Equipment as contemplated by this Agreement. Customer further
represents and warrants that its placement, arrangement, and use of the Customer
Equipment in the Internet Data Centers complies with the Customer Equipment
Manufacturer's environmental and other specifications.

      (b) Customer's Business. Customer represents and warrants that Customer's
services, products, materials, data, information and Customer Equipment used by
Customer in connection with this Agreement as well as Customer's and its
permitted customer's and users' use of the Internet Data Center Services
(collectively, "Customers' Business") does not as of the Installation Date, and
will not during the term of this Agreement operate in any manner that would
violate any applicable law or regulation.

      (c) Rules and Regulations. Customer has read the Rules and Regulations and
represents and warrants that Customer and Customer's Business are currently in
full compliance with the Rules and Regulations, and will remain so at all times
during the term of this Agreement.

      (d) Breach of Warranties. In the event of any breach, or reasonably
anticipated breach, of any of the foregoing warranties, in addition to any other
remedies available at law or in equity, Exodus will have the right immediately,
in Exodus' sole discretion, to suspend any related Internet Data Center Services
if deemed reasonably necessary by Exodus to prevent any harm to Exodus and its
business.

      5.2 Warranties and Disclaimers by Exodus.

            5.2(a) Service Level Warranty. In the event Customer experiences any
of the following and Exodus determines in its reasonable judgment that such
inability was caused by Exodus' failure to provide Internet Data Center Services
for reasons within Exodus' reasonable control and not as a result of any actions
or inactions of Customer or any third


EXODUS COMMUNICATIONS, INC. CONFIDENTIAL AND PROPRIETARY (rev 6/98)       Page 1
<PAGE>

parties(including Customer Equipment and third party equipment), Exodus will,
upon Customer's request in accordance with paragraph (iii) below, credit
Customer's account as described below:

            (i) Inability to Access the Internet (Downtime). If Customer is
unable to transmit and receive information from Exodus' Internet Data Centers
(i.e., Exodus' LAN and WAN) to other portion of the Internet because Exodus
failed to provide the Internet Data Center Services for more than fifteen (15)
consecutive minutes, Exodus will credit Customer's account the pro-rata
connectivity charges (i.e., all bandwidth related charges) for (1) day of
service, up to an aggregate maximum credit of connectivity charges for seven (7)
days of service in any one calendar (1) month. Exodus' scheduled maintenance of
the Internet Data Centers and Internet Data Center Services, as described in the
Rules and Regulations, shall not be deemed to be a failure of Exodus to provide
Internet Data Center Services. For purposes of the foregoing, "unable to
transmit and receive" shall mean sustained packet loss in excess of 50% based on
Exodus' measurements.

            (ii) Packet Loss and Latency. Exodus does not proactively monitor
the packet loss or transmission latency of specific customers. Exodus does,
however, proactively monitor the aggregate packet loss and transmission latency
within its LAN and WAN. In the event that Exodus discovers (either from its own
efforts or after being notified by Customer) that Customer is experiencing
packet loss in excess of one percent (1%) ("Excess Packet Loss") or transmission
latency in excess of 120 milliseconds round trip time (based on Exodus'
measurements) between any two Internet Data Centers within Exodus' U.S. network
(collectively, "Excess Latency", and with Excess Packet Loss "Excess Packet
Loss/Latency"), and Customer notifies Exodus (or confirms that Exodus has
notified Customer), Exodus will take all actions necessary to determine the
source of Excess Packet Loss/Latency.

                  (A) Time to Discover Source of Excess Packet Loss/Latency;
Notification of Customer. Within two (2) hours of discovering the existence of
Excess Packet Loss/Latency, Exodus will determine whether the source of the
Excess Packet Loss/Latency is limited to the Customer Equipment and the Exodus
equipment connecting the Customer Equipment to Exodus' LAN ("Customer Specific
Packet Loss/Latency"). If the Excess Packet Loss/Latency is not a Customer
Specific Packet Loss/Latency, Exodus will determine the source of the Excess
Packet Loss/Latency within two (2) hours after determining that it is not a
Customer Specific Packet Loss/Latency. In any event, Exodus will notify Customer
of the source of the Excess Packet Loss/Latency within sixty (60) minutes after
identifying the source.

                  (B) Remedy of Excess Packet Loss/Latency. IF the Excess Packet
Loss/Latency remedy is within the sole control of Exodus, Exodus will remedy the
Excess Packet Loss/Latency within two (2) hours of determining the source of the
Excess Packet Loss/Latency. If the Excess Packet Loss/Latency is caused from
outside of the Exodus LAN or WAN, Exodus will notify Customer and will use
commercially reasonable efforts to notify the party(ies) responsible for the
source and cooperate with it(them) to resolve the problem as soon as possible.

                  (C) Failure to Determine Source and/or Resolve Problem. In the
event that Exodus is unable to determine the source of and remedy the Excess
Packet Loss/Latency within the time periods described above (where Exodus was
solely in control of the source), Exodus will credit Customer's account the
pro-rata connectivity charges for one (1) day of service for every two (2) hours
after the time periods described above that it takes Exodus to resolve the
problem, up to an aggregate maximum credit of connectivity charges for seven (7)
days of service in any one (1) month.

            (iii) Customer Must Request Credit: To receive any of the credits
described in this section 5.2(a), Customer must notify Exodus within three (3)
business days from the time Customer becomes eligible to receive a credit.
Failure to comply with this requirement will forfeit Customer's right to receive
a credit.

            (iv) Remedies Shall Not Be Cumulative; Maximum Credit: In the event
that Customer is entitled to multiple credits hereunder arising from the same
event, such credits shall not be cumulative and Customer shall be entitled to
receive only the maximum single credit available for such event. In no event
will Exodus be required to credit Customer in any one (1) calendar month
connectivity charges in excess of seven (7) days of service. A credit shall be
applied only to the month in which there was the incident that resulted in the
credit. Customer shall not be eligible to receive any credits for periods in
which Customer received any Internet Data Center Services free of charge.

            (v) Termination Option for Chronic Problems: If, in any single
calendar month, Customer would be able to receive credits totaling fifteen (15)
or more days (but for the limitation in paragraph (iv) above) resulting from
three (3) or more events during such calendar month or, if any single event
entitling customer to credits under paragraph 5.2(a)(i) exists for a period of
eight (8) consecutive hours, then, Customer may terminate this Agreement for
cause and without penalty by notifying Exodus within five (5) days following the
end of such calendar month. Such termination will be effective thirty (30) days
after receipt of such notice by Exodus.

THIS WARRANTY DOES NOT APPLY TO ANY INTERNET DATA CENTER SERVICES THAT EXPRESSLY
EXCLUDE THIS WARRANTY (AS DESCRIBED IN THE SPECIFICATION SHEETS FOR SUCH
PRODUCTS). THIS SECTION 5.2(a) STATES CUSTOMER'S SOLE AND EXCLUSIVE REMEDY FOR
ANY FAILURE BY EXODUS TO PROVIDE INTERNET DATA CENTER SERVICES.

      (b) No Other Warranty. EXCEPT FOR THE EXPRESS WARRANTY SET OUT IN
SUBSECTION (a) ABOVE, THE INTERNET DATA CENTER SERVICES ARE PROVIDED ON AN "AS
IS" BASIS, AND CUSTOMER'S USE OF THE INTERNET DATA CENTER SERVICES IS AT ITS OWN
RISK. EXODUS DOES NOT MAKE, AND HEREBY DISCLAIMS, ANY AND ALL OTHER EXPRESS
AND/OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT AND TITLE,
AND ANY WARRANTIES ARISING FROM A COURSE OF DEALING, USAGE, OR TRADE PRACTICE.
EXODUS DOES NOT WARRANT THAT THE INTERNET DATA CENTER SERVICES WILL BE
UNINTERRUPTED, ERROR FREE, OR COMPLETELY SECURE.

      (c) Disclaimer of Actions Caused by and/or Under the Control of Third
Parties. EXODUS DOES NOT AND CANNOT CONTROL THE FLOW OF DATA TO OR FROM EXODUS'
INTERNET DATA CENTERS AND OTHER PORTIONS OF THE INTERNET. SUCH FLOW DEPENDS IN
LARGE PART ON THE PERFORMANCE OF INTERNET SERVICES PROVIDED OR CONTROLLED BY

Goods. Any dispute relating to the terms, interpretation or performance of this
Agreement (other than claims for preliminary injunctive relief or other

such consent will be void. Exodus may assign this Agreement in whole or in part.
This Agreement will bind and inure to the benefit of each party's successors and
permitted assigns. Any notice or communication required or permitted to be given
hereunder may be delivered by hand, deposited with an overnight courier, sent by
confirmed facsimile, or mailed by registered or certified mail, return receipt
requested, postage prepaid, in each case to the address of the receiving party
indicated on the signature page hereof, or at such other address as may
hereafter be furnished in writing by either party hereto to the other. Such
notice will be deemed to have been given as of the date it is delivered, mailed
or sent, whichever is earlier.

      9.8 Relationship of Parties. Exodus and Customer are independent
contractors and this Agreement will not establish any relationship of
partnership, joint venture, employment, franchise or agency between Exodus and
Customer. Neither Exodus nor Customer will have the power to bind the other or
incur obligations on the other's behalf without the other's prior written
consent, except as otherwise expressly provided herein.

      9.9 Entire Agreement; Counterparts. This Agreement, including all
documents incorporated herein by reference, constitutes the complete and
exclusive agreement between the parties with respect to the subject matter
hereof, and supersedes and replaces any and all prior or contemporaneous
discussions, negotiations, understandings and agreements, written and oral,
regarding such subject matter. This Agreement may be executed in two or more
counterparts, each of which will be deemed an original, but all of which

has remedied such fault and (ii) the date the "Customer Equipment" (Customer's
computer hardware and other tangible equipment, as identified in the Customer

upon written notice to Customer, modify the payment terms to require full
payment before the provision of Internet Data Center Services or other
assurances to secure Customer's payment obligations hereunder.

except as expressly permitted by this Agreement, not disclose to any third party

advisors as reasonably necessary), any of the other party's Confidential
Information and will take reasonable precautions to protect the confidentiality
of such information.

      4.2 Exceptions. Information will not be deemed Confidential Information

known or otherwise ceases to be secret or confidential, except through a breach
of this Agreement by the receiving party; or (iv) is independently developed by
the receiving party.

5. REPRESENTATIONS AND WARRANTIES.

      5.1 Warranties by Customer.

      (a) Customer Equipment. Customer represents and warrants that it owns or
has the legal right and authority, and will continue to own or maintain the
legal right and authority during the term of this Agreement, to place and use
the Customer Equipment as contemplated by this Agreement. Customer further
represents and warrants that its placement, arrangement, and use of the Customer
Equipment in the Internet Data Centers complies with the Customer Equipment
Manufacturer's environmental and other specifications.

      (b) Customer's Business. Customer represents and warrants that Customer's
services, products, materials, data, information and Customer Equipment used by
Customer in connection with this Agreement as well as Customer's and its
permitted customers' and users' use of the Internet Data Center Services
(collectively, "Customer's Business") does not as of the Installation Date, and
will not during the term of this Agreement operate in any manner that would
violate any applicable law or regulation.

      (c) Rules and Regulations. Customer has read the Rules and Regulations and
represents and warrants that Customer and Customer's Business are currently in
full compliance with the Rules and Regulations, and will remain so at all times
during the term of this Agreement.

      (d) Breach of Warranties. In the event of any breach, or reasonably
anticipated breach, of any of the foregoing warranties, in addition to any other
remedies available at law or in equity, Exodus will have the right immediately,
in Exodus' sole discretion, to suspend any related Internet Data Center Services
if deemed reasonably necessary by Exodus to prevent any harm to Exodus and its
business.

      5.2 Warranties and Disclaimers by Exodus.

            5.2(a) Service Level Warranty. In the event Customer experiences any
of the following and Exodus determines in its reasonable judgment that such
inability was caused by Exodus' failure to provide Internet Data Center Services
for reasons within Exodus' reasonable control and not as a result of any actions
or inactions of Customer or any third
<PAGE>

parties (including Customer Equipment and third party equipment), Exodus will,
upon Customer's request in accordance with paragraph (iii) below, credit
Customer's account as described below:

            (i) Inability to Access the Internet (Downtime). If Customer is
unable to transmit and receive information from Exodus' Internet Data Centers
(i.e., Exodus' LAN and WAN) to other portions of the Internet because Exodus
failed to provide the Internet Data Center Services for more than fifteen (15)
consecutive minutes, Exodus will credit Customer's account the pro-rata
connectivity charges (i.e., all band width related charges) for one (1) day of
service, up to an aggregate maximum credit of connectivity charges for seven (7)
days of service in any one calendar (1) month. Exodus' scheduled maintenance of
the Internet Data Centers and Internet Data Center Services as described in the
Rules and Regulations, must not be deemed to be a failure of Exodus to provide
Internet Data Center Services. For purposes of the foregoing, "unable to
transmit and receive" shall mean sustained partial loss in excess of 50% based
on Exodus' measurements.

            (ii) Packet Loss and Latency. Exodus does not proactively monitor
the packet loss or transmission latency of specific customers. Exodus does,
however, proactively monitor the aggregate packet loss and transmission latency
within LAN and WAN. In the event that Exodus discovers (either from its own
efforts or after being notified by Customer) that Customer is experiencing
packet loss in excess of one percent (1%) ("Excess Packet Loss") or transmission
latency in excess of 120 milliseconds round trip time (based on Exodus'
measurements) between any two Internet Data Centers within Exodus' U.S. network
(collectively, "Excess Latency", and with Excess Packet Loss "Excess Packet
Loss/Latency") and Customer notifies Exodus (or confirms that Exodus has
notified Customer), Exodus will create all actions necessary to determine the
source of the Excess Packet Loss Latency.

                  (A) Time to Discover Source of Excess Packet Loss/Latency:
Notification of Customer. Within two (2) hours of discovering existence of
Excess Packet Loss/Latency, Exodus will determine whether the source of the
Excess Packet Loss/Latency is limited to the Customer Equipment and the Exodus
equipment connecting the Customer Equipment to Exodus' LAN ("Customer Specific
Packet Loss/Latency"). If the Excess Packet Loss/Latency is not a Customer
specific Packet Loss/Latency, Exodus will determine the source of the Excess
Packet Loss/Latency within two (2) hours after determining that it is not a
Customer Specific Packet Loss/Latency. In any event, Exodus will notify Customer
of the source of the Excess Packet Loss/Latency within sixty (60) minutes after
identifying the source.

                  (B) Remedy of Excess Packet Loss/Latency. If the Excess Packet
Loss/Latency remedy is within the sole control of Exodus, Exodus will remedy the
Excess Packet Loss/Latency within two (2) hours of determining the source of the
Excess Packet Loss/Latency. If the Excess Packet Loss/Latency is caused from
outside of the Exodus LAN or WAN, Exodus will notify Customer and will use
commercially reasonably efforts to notify the party(ies) responsible for the
source and cooperate with it (them) to resolve the problem as soon as possible.

                  (C) Failure to Determine Source and/or Resolve Problem: In the
event that Exodus is unable to determine the source and remedy the Excess Packet
Loss/Latency within the time periods described above (where Exodus was solely in
control of the source), Exodus will credit Customer's account the pro-rata
connectivity charges for one (1) day of service for every two (2) hours after
the time periods described above that it takes Exodus to resolve the problem, up
to an aggregate maximum credit of connectivity charges for seven (7) days of
service in any one (1) month.

      (iii) Customer Must Request Credit: To receive any of the credit described
in this section 5.2(a), Customer must notify Exodus within three (3) business
days from the time Customer becomes eligible to receive credit. Failure to
comply with this requirement will forfeit Customer's right to receive a credit.

      (iv) Remedies Shall Not Be Cummulative; Maximum Credit: In the event that
Customer is entitled to multiple credit hereunder arising from the same event,
such credits shall not be cummulative and Customer shall be entitled to receive
only the maximum single credit available for such event. In no event will Exodus
be required to credit Customer in any one (1) calendar month connectivity
charges in excess of seven (7) days of service. A credit shall be applied only
to the month in which there was the incident that resulted in the credit.
Customer shall not be eligible to receive any credit for periods in which
Customer received any Internet Data Center Services free of charge.

      (v) Termination Option for Chronic Problems: If, in any single calendar
month, Customer would be able to receive credits totaling fifteen (15) or more
days (but for the limitation in paragraph (iv) above) resulting from three (3)
or more events during such calendar month or, if any single event [ILLEGIBLE]
customer to credits under paragraph 5.2(a)(i) exists for a period of eight (8)
consecutive hours, then, Customer may terminate this Agreement for cause and
without penalty by notifying Exodus within five (5) days following the end of
such calendar month. Such termination will be effective thirty (30) days after
receipt of such notice by Exodus.

THIS WARRANTY DOES NOT APPLY TO ANY INTERNET DATA CENTER SERVICES THAT EXPRESSLY
EXCLUDE THIS WARRANTY (AS DESCRIBED IN THE SPECIFICATION SHEETS FOR SUCH
PRODUCTS). THIS SECTION 5.2(a) STATES CUSTOMER'S SOLE AND EXCLUSIVE REMEDY FOR
ANY FAILURE BY EXODUS TO PROVIDE INTERNET DATA CENTER SERVICES.

      (b) No Other Warranty. EXCEPT FOR THE EXPRESS WARRANTY SET OUT IN

contractors and this Agreement will not establish any relationship of
partnership, joint venture, employment, franchise or agency between Exodus and

                                                         Agreement #____________
                                     impsat

                              TERMS AND CONDITIONS

      IMPSAT USA and Customer agree that this Service Agreement shall be
      governed by the following terms and conditions

1.    Service Acceptance
      Acceptance of service shall be deemed to occur upon IMPSAT USA's
      certification that service related equipment and service has been
      installed and upon certification of the service by Customer. For each
      such service, Customer shall provide an INTERNET electronic mail address
      to which IMPSAT USA shall send such certification. Certification of the
      service by Customer shall be deemed to have occurred twenty-four (24)
      hours after certification is sent by IMPSAT USA unless Customer certifies
      in writing to IMPSAT USA within that period that the service is
      experiencing a high rate of errors and provides evidence thereof. If
      Customer does not accept the service, IMPSAT USA shall retest the service
      and equipment for a period of (24) hours. If service is found to be
      acceptable, and/or is determined that the problem exists in the Customers
      equipment, IMPSAT USA, shall then have the right to commence billing for
      the service as of the original certification date.

2.    Price Schedule (not including taxes applicable in each country). The
      prices for the communications services shall be as set forth in the
      Service Agreement on page 1 for each service and each term of service
      stated therein. These prices are in U.S. dollars and are net to IMPSAT USA
      in all cases. Customer shall be responsible for the payment of any and all
      applicable fees, charges, taxes, and/or withholdings including, but not
      limited to contributions to Universal Service support mechanisms on the
      service at the time of invoice by IMPSAT USA and its affiliates providing
      service at the non-USA service sites.

3.    Termination by Customer. Customer may terminate Service upon sixty (60)
      days written notice to IMPSAT USA's corporate office, computed from the
      date of receipt by IMPSAT USA of the notice. The termination of this
      Agreement for any reason shall extinguish all of IMPSAT USA's obligations
      to provide, and Customer's obligations to accept IMPSAT USA service but
      shall not relieve either party of any remaining obligations that are
      applicable under this Agreement.

4.    Payment Schedule A. Non-recurring charge shall be invoiced 100% within
      five (5) working days of Agreement signature and 50% within five (5)
      working days of acceptance of service. Customer shall pay invoiced amount
      in full within ten (10) calendar days of the invoice date. B. The monthly
      recurring charge will be invoiced at the beginning of each month for
      service beginning on the first (1st) day of same month Customer
      shall pay this invoice in full no later than the 15th of each month. C.
      Payments not made as provided in Clauses 4A, 4B, shall accrue interest at
      the rate of one and one-half percent (1.5%) per month, or at the highest
      rate allowed by law, whichever is less, from the invoice date until paid.
      Failure of Customer to pay any amounts when due shall constitute
      sufficient cause for IMPSAT USA to terminate service to Customer under
      this Agreement.

5.    Renewal and Cancellation of Service After Expiration of Agreement At
      the end of the Agreement term, service will be automatically renewed for a
      like period unless Customer signs a new service Agreement or cancels the
      service in writing as provided herein at least sixty (60) days prior to
      the expiration of the service period. The rate for service shall be at the
      price and on the terms and conditions of IMPSAT USA then in effect at the
      time of renewal.

6.    Confidential Information

      6.1 Confidential Information. Each party acknowledges that it will have
access to certain confidential information of the other party concerning the
other party's business, plans, customers, technology, and products, including
the terms and conditions of this Agreement ("Confidential Information").
Confidential Information will include, but not be limited to, each party's
proprietary software and Customer information. Each party agrees that it will
not use in any way, for its own account or the account of any third party,
except as expressly permitted by this Agreement, nor disclose to any third
party (except as required by law or to that party's attorneys, accountants
and other advisors as reasonably necessary), any of the other party's
Confidential Information and will take reasonable precautions to protect the
confidentiality of such information.

      6.2 Exceptions. Information will not be deemed Confidential Information

receipt from the disclosing party directly or indirectly from a source other
than one having an obligation of confidentiality to the disclosing party;

the receiving party directly or indirectly from a source other than one
having an obligation of confidentiality to the disclosing party;
(iii) becomes publicly known or otherwise ceases to be secret or

party; or (iv) is independently developed by the receiving party.

7.    Representations and Warranties

      7.1   Warranties by Customer.

      (a) Customer Equipment. Customer represents and warrants that it owns
or has the legal right and authority, and will continue to own or maintain

                                                         Agreement #____________
                                     impsat

      (b) Customer's Business. Customer represents and warrants that
Customer's services, products, materials, data, information and Customer
Equipment used by Customer in connection with this Agreement as well as
Customer's and its permitted customers' and users' use of the Internet Data
Center Services (collectively, "Customer's Business") does not as of the
Installation Date, and will not during the term of this Agreement operate in
any manner that would violate any applicable law or regulation.

      (c) Breach of Warranties. In the event of any breach, or reasonably
anticipated breach, of any of the foregoing warranties, in addition any other
remedies available at law or in equity, IMPSAT USA will have the right
immediately, in IMPSAT USA's sole discretion, to suspend any related Internet
Data Center Services if deemed reasonably necessary by IMPSAT USA to prevent
any harm to IMPSAT USA and its business.

      7.2   Warranties and Disclaimers by IMPSAT USA.

      7.2 (a) Service Level Warranty. In the event Customer experiences any
of the following and IMPSAT USA determines in its reasonable judgment that
such inability was caused by IMPSAT USA's failure to provide Internet Data
Center Services for reasons within IMPSAT USA's reasonable control and not as
a result of any actions or inaction of Customer or any third parties
(including Customer Equipment and third party equipment), IMPSAT USA will,
upon Customer's request in accordance with paragraph (iii) below, credit
Customer's account as described below:

            (i) Inability to Access the Internet (Downtime). If Customer is
unable to transmit and receive information from IMPSAT USA's Internet Data
Centers (i.e., IMPSAT USA's LAN and WAN) to other portions of the Internet
because IMPSAT USA failed to provide the Internet Data Center Services,
IMPSAT USA will credit Customer's account the pro-rata connectivity charges
(i.e., all bandwidth-related charges) according to the table below. IMPSAT
USA's scheduled maintenance of the Internet Data Centers and Internet Data
Center Services, shall not be deemed to be a failure of IMPSAT USA to provide
Internet Data Center Services. IMPSAT USA must notify the Customer of any
maintenance or related tasks that may cause a service downtime. Any service
interruption without a prior notification shall be deemed to be failure of
IMPSAT USA. For purposes of the foregoing, "unable to transmit and receive"
shall mean sustained packet loss in excess of 50% based on IMPSAT USA's
measurements.

             Total Monthly Outage Time          Service credit percentage
             -------------------------          -------------------------

             Less than or equal to 1 hour                  5%

             Greater than one hour                         10%

             Greater than two hours                        20%

            (ii) Packet Loss and Latency. IMPSAT USA does not proactively
monitor the packet loss or transmission latency of specific customers. IMPSAT
USA does, however, proactively monitor the aggregate packet loss and
transmission latency within its LAN and WAN. In the event that IMPSAT USA
discovers (either from its own efforts or after being notified by Customer)
that Customer is experiencing packet loss in excess of one percent (1%)
("Excess Packet Loss") or transmission latency in excess of 120 milliseconds
round trip time (based on IMPSAT USA'S measurements) between IMPSAT USA
Internet Data Centers and the Internet Backbone (collectively, "Excess
Latency," and with Excess Packet Loss "Excess Packet Loss/Latency"), and
Customer notifies IMPSAT USA (or confirms that IMPSAT USA has notified
Customer), IMPSAT USA will take all actions necessary to determine the source
of the Excess Packet Loss/Latency.

                  (A) Time to Discover Source of Excess Packet Loss/Latency;
Notification of Customer. Within two (2) hours of discovering the existence
of Excess Packet Loss/Latency, IMPSAT USA will determine whether the source
of the Excess Packet Loss/Latency is limited to the Customer Equipment and
the IMPSAT USA equipment connecting the Customer Equipment to IMPSAT USA'S
LAN ("Customer Specific Packet Loss/Latency"). If the Excess Packet
Loss/Latency is not a Customer Specific Packet Loss/Latency, IMPSAT/ USA will
determine the source of the Excess Packet Loss/Latency within two (2) hours
after determining that it is not a Customer Specific Packet Loss/Latency. In
any event, IMPSAT USA will notify Customer of the source of the Excess Packet
Loss/Latency within sixty (60) minutes after identifying the source.

                  (B) Remedy of Excess Packet Loss/Latency. If the Excess Packet
Loss/Latency remedy is within the sole control of IMPSAT USA, IMPSAT USA will
remedy the Excess Packet Loss/Latency within two (2) hours of determining the
source of the Excess Packet Loss/Latency. If the Excess Packet Loss/Latency is
caused from outside of the IMPSAT USA LAN or WAN, IMPSAT USA will notify
Customer and will use commercially reasonable efforts to notify the party(ies)
responsible for the source and cooperate with it(them) to resolve the problem as
soon as possible.

                  (C) Failure to Determine Source and/or Resolve Problem. In the
event that IMPSAT USA is unable to determine the source of and remedy the Excess
Packet Loss/Latency within the time periods described above (where IMPSAT USA
was solely in control of the source), IMPSAT USA will credit Customer's account
the pro-rata connectivity charges according to the table below after the time
period described above that it takes IMPSAT USA to resolve the problem.

            (iii) Customer Must Request Credit: To receive any of the credits
described in this section 5.2(a), Customer must notify IMPSAT USA within
three (3) business days from the time Customer becomes eligible to receive a
credit. Failure to comply with this requirement will waive Customer's right
to receive a credit.

            (iv) Remedies Shall Not Be Cumulative: Maximum Credit: In the
event that Customer is entitled to multiple credits hereunder arising from
the same event, such credits shall not be cumulative and Customer shall be
entitled to receive only the maximum single credit available for such event.
A credit shall be applied only to the month in which there was the incident
that resulted in the credit. Customer shall not be eligible to receive any
credits for periods in which Customer received any Internet Data Center
Services free of charge.

                  (A) Service credits issued in any month under this Service
                      Level Guarantee under this Agreement will not exceed 30%
                      of the monthly recurring charges.

                  (B) Service credits issued during a Contract Year under this
                      Service Level Guarantee under this Agreement will not
                      exceed 20% of Customer's Services invoiced during
                      the Contract Year.

            (v) Termination Option for Chronic Problems: If, in any single
calendar month, Customer would be able to receive credits resulting from
three (3) or more events during such calendar month or, if any single event
entitling customer to credits under paragraph 5.2(a)(i) exists for a
period of twelve (12) consecutive hours, then, Customer may terminate this
Agreement for cause and without penalty by notifying IMPSAT USA within five (5)
days following the end of such calendar month. Such termination will be
effective thirty 30 days after receipt of notice by IMPSAT USA.

      (b) No Other Warranty. EXCEPT FOR THE EXPRESS WARRANTY SET OUT IN
SUBSECTION (a) ABOVE, THE INTERNET DATA CENTER SERVICES ARE PROVIDED ON AN
"AS IS" BASIS, AND CUSTOMER'S USE OF THE INTERNET DATA CENTER SERVICES IS AT
ITS OWN RISK. IMPSAT USA DOES NOT MAKE, AND HEREBY Disclaims, ANY AND ALL
OTHER EXPRESS AND/OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
NONINFRINGEMENT AND TITLE, AND ANY WARRANTIES ARISING FROM A COURSE OF
DEALING, USAGE, OR TRADE PRACTICE. IMPSAT USA DOES NOT WARRANT THAT THE
INTERNET DATA CENTER SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, OR
COMPLETELY SECURE.

      (c) Disclaimer of Actions Caused by and/or Under the Control of Third
Parties. IMPSAT USA DOES NOT AND CANNOT CONTROL FLOW OF DATA TO OR FROM
IMPSAT USA'S INTERNET DATA CENTERS AND OTHER PORTIONS OF THE INTERNET. SUCH
FLOW DEPENDS IN LARGE PART ON THE PERFORMANCE OF INTERNET SERVICES PROVIDED
OR CONTROLLED BY THIRD PARTIES. AT TIMES, ACTIONS OR INACTIONS CAUSED BY
THESE THIRD PARTIES CAN PRODUCE SITUATIONS IN WHICH IMPSAT USA'S CUSTOMERS'
CONNECTIONS TO THE INTERNET (OR PORTIONS THEREOF) MAY BE IMPAIRED OR
DISRUPTED. ALTHOUGH IMPSAT USA WILL USE COMMERCIALLY REASONABLE EFFORTS TO
TAKE ACTIONS IT DEEMS APPROPRIATE TO REMEDY AND AVOID SUCH EVENTS, IMPSAT USA
CANNOT GUARANTEE THAT THEY WILL NOT OCCUR. ACCORDINGLY, IMPSAT USA DISCLAIMS
ANY AND ALL LIABILITY RESULTING FROM OR RELATED TO SUCH EVENTS.

8.    Limitations of Liability.

      8.1 PERSONAL Injury. EACH REPRESENTATIVE AND ANY OTHER PERSONS VISITING
THE INTERNET DATA CENTERS DOES SO AT ITS OWN RISK AND IMPSAT USA ASSUMES NO
LIABILITY WHATSOEVER FOR ANY HARM TO SUCH PERSONS RESULTING FROM ANY CAUSE
OTHER THAN IMPSAT USA'S NEGLIGENCE OR WILLFUL MISCONDUCT RESULTING IN
PERSONAL INJURY TO SUCH PERSONS DURING SUCH A VISIT.

      8.2 Damage to Customer Equipment or Business. IMPSAT USA ASSUMES NO
LIABILITY FOR ANY DAMAGE TO, OR LOSS RELATING TO CUSTOMER'S BUSINESS
RESULTING FROM ANY CAUSE WHATSOEVER. CERTAIN CUSTOMER EQUIPMENT, INCLUDING
BUT NOT LIMITED TO CUSTOMER EQUIPMENT LOCATED ON CYBERRACKS, MAY BE DIRECTLY
ACCESSIBLE BY OTHER CUSTOMERS. IMPSAT USA ASSUMES NO LIABILITY FOR ANY DAMAGE
TO, OR LOSS OF, ANY CUSTOMER EQUIPMENT RESULTING FROM ANY CAUSE OTHER THAN
IMPSAT USA'S NEGLIGENCE OR WILLFUL MISCONDUCT. TO THE EXTENT IMPSAT USA IS
LIABLE FOR ANY DAMAGE TO, OR LOSS OF, THE CUSTOMER EQUIPMENT FOR ANY REASON,
SUCH LIABILITY WILL BE LIMITED SOLELY TO THE THEN-CURRENT VALUE OF THE
CUSTOMER EQUIPMENT.

      8.3 EXCLUSIONS. EXCEPT AS SPECIFIED IN SECTIONS 6.1 AND 6.2, IN NO
EVENT WILL IMPSAT USA BE LIABLE TO CUSTOMER'S REPRESENTATIVE, OR ANY THIRD
PARTY FOR ANY CLAIMS ARISING OUT OF OR RELATED TO THIS AGREEMENT, CUSTOMER

      8.5 Customer's Insurance. Customer agrees that it will not pursue any
claims against IMPSAT USA for any liability IMPSAT USA may have under or

resolve(s) such claims.

      8.6 Basis of the Bargain; Failure of Essential Purpose. Customer
acknowledges that IMPSAT USA has set its prices and entered into this
Agreement in reliance upon the limitations of liability and the disclaimers
of warranties and damages set forth herein, and that the same form an
essential basis of the bargain between the parties. The parties agree not to
pursue remedies contrary to the limitations and exclusive of liability and
disclaimers specified in this Agreement will survive and apply even if

section shall survive the termination of the Agreement.

9.    Force Majeure.

      Neither party shall be in default or otherwise liable for any delay in or

      arises by any reason beyond that party's reasonable control, including any

      that lack of funds shall not be deemed to be a reason beyond a party's
      reasonable control. The parties will promptly inform and consult with

      could be the cause of a delay or failure in the performance of this

12.   Non-Waiver.

      No forbearance by either party to enforce any provision under this

      modification of this Agreement.

13.   Jurisdiction and Governing Law.

      This Agreement shall be governed by the laws of the State of Florida,

      A.(i) If either party breaches any term or condition of this Agreement and
      such breach can reasonably be cured (other than default for event
      specified in Section 13 B), the non-defaulting party shall notify the
      defaulting party in writing and grant the defaulting party a minimum
      period of 15 days to cure such default following the date of the notice.
      The nondefaulting party may, in its discretion, grant additional time
      in which to cure as the defaulting party may require if the
      nondefaulting party reasonably believes that the defaulting party is
      diligently pursuing a cure for the breach.

      (ii) If the defaulting party does not cure the default within such 15-day
      period, or if, at any time during the additional period granted for cure,
      the non-defaulting party reasonably believes that the defaulting party is
      not making diligent efforts to cure the default, the non-defaulting party
      may immediately terminate this Agreement by written notice to the
      defaulting party.

      B. Any of the following events will constitute a default of this Agreement
      by Customer and give IMPSAT USA the right to terminate Agreement upon 5
      days notice to Customer.

            (i)   Nonpayment of any portion of the nonrecurring charge within 15
                  days of the date such payment becomes due,

            (ii)  Nonpayment of any portion of the monthly recurring charge

      Customer shall submit within fifteen (15) days following the date of
      invoice, full payment of the undisputed portion of the invoice, and
      written documentation identifying and substantiating the disputed
      amount. If Customer does not report a dispute within the fifteen (15) day
      period Customer shall have waived its dispute rights for that invoice
      IMPSAT USA and Customer agree to use their respective best efforts to
      resolve any dispute with fifteen (15) days after IMPSAT USA receives
      written notice of the dispute from Customer. Any disputed amounts resolved
      in favor of Customer shall be credited to Customer's account on the next
      invoice following resolution of the dispute. Any disputed amounts
      determined to be payable to IMPSAT USA shall  within ten (10) days of
      the resolution of the dispute. Any dispute arising out of or relating to
      this agreement which has not been resolved by the good faith efforts of
      the parties will be settled by binding arbitration. Any controversy or
      claim arising out of or relating to this Agreement shall be finally
      settled by arbitration in Fort Lauderdale, Florida and shall be resolved
      under the laws of the State of Florida. The arbitration shall be conducted
      before a single arbitrator in accordance with the commercial rules and
      practices of the American Arbitration Association then in effect.

16.   Entire Agreement.

      The attached Conditions of Service, Installation, and Maintenance and any

      part of the present Agreement. This Agreement constitutes the entire and
      exclusive statement of the rights, obligations and understandings of the

Avenida Belgrano, 845
Fourth Floor

Argentina

                                LETTER AGREEMENT

Ladies and Gentlemen:

            Subject to the terms and conditions set forth below, El Sitio
International Corporation ("El Sitio") hereby agrees to sell, and TV Azteca,
S.A. de C.V. ("TVA") hereby agrees to purchase in exchange for certain services,
certain shares of preferred stock of El Sitio.

            1. Shares to be Purchased. (a) TVA will purchase from El Sitio newly
issued shares ("Shares") or preferred stock of El Sitio that are fungible with
the Shares to be offered in the private placement currently contemplated by El
Sitio (the "Private Placement"), in exchange for Consideration (as defined in
paragraph 2), on a quarterly basis over a period of three years. Beginning on
the last day of the three-month period after Closing (as defined in paragraph
6), and every successive three-month period thereafter, El Sitio agrees to issue
and transfer Shares to TVA in an amount equal to (x) the Consideration TVA is
deemed to provide during the relevant three-month period (as set forth in
Schedule A), divided by (y) the Share Price. For purposes of this letter
agreement, "Share Price" means the price per Share at which the Shares are sold
by El Sitio in the Private Placement.

            (b) El Sitio represents and warrants that, when issued to TVA in
accordance with this letter agreement, the Shares purchased by TVA hereunder,
including, without limitation, any

<PAGE>
                                                                              2.


additional Shares purchased pursuant to paragraph 3, will be duly authorized,
validly issued, fully paid and nonassessable.

      (c) In the event of any failure by El Sitio to issue and transfer Shares
in accordance with paragraph 1(a) or if the representation and warranty
described in paragraph 1(b) shall prove to be incorrect in any material respect,
without prejudice to any other remedy provided by law, TVA will be entitled to
cease performance of the services described in paragraphs 2, 3 and 5.

            2. Consideration. (a) In consideration for the purchase of Shares,
TVA agrees to provide El Sitio with television advertising time on TVA's
television channels equivalent in value to the following amounts (which amounts
shall be based on rates actually charged to similarily-situated clients of TVA
at the time): (i) US$1,500,000 in the first year; (ii) US$1,000,000 in the
second year; and (iii) US$1,000,000 in the third year. For purposes of
calculating the amount of Shares to be issued under paragraph 1, in any given
year, TVA shall be deemed to provide one-fourth of the advertising due in such
year during each quarter of such year. The net present value of such advertising
time, calculated using an annual discount rate of 30%, shall constitute the
"Consideration" for purposes of this letter agreement. Schedule A sets forth for
each quarter of each year during which TVA is obligated to deliver advertising
time, the actual value and the net present value of the advertising time TVA
will be deemed to have delivered.

            (b) El Sitio shall use TVA's standard service order form to request
the times and/or channels which it elects for advertising and TVA will treat
such a request in the same manner in which treats similar requests from
cash-paying clients. The value of television advertising time made available to
El Sitio will qualify as Consideration regardless of whether El Sitio actually
uses such time; provided that if El Sitio does not use all the advertising time
to which it is entitled in any given year, TVA agrees to provide El Sitio with
advertising time of an equivalent value (measured at the then applicable rates)
which El Sitio may use at a future date, so long as such future date shall be no
later than 42 months after Closing.

                                                                              3.


            3. Purchase of Additional Shares. TVA agrees to use reasonable
efforts to enter into barter arrangements with third parties (i) to reduce El
Sitio's cash infrastructure and promotional costs related to office space and
other overhead expenses, and (ii) to reduce El Sitio's cash costs related to the
promotional event described in paragraph 5(b), in the event that such event is
held at a location at which TVA has barter arrangement in place. Any cash
savings for El Sitio obtained by TVA through such arrangements (as mutually
agreed in good faith by the parties hereto) shall be treated as additional
consideration for the purchase of Shares. Promptly (and in any event within 15
days) after realizing any such cash savings, El Sitio agrees to issue Shares in
an amount equal to (x) such additional consideration, divided by (y) the Share
Price.

            4. Subscription Agreement. Following execution of this letter
arrangement the parties shall commence preparation of a definitive subscription
agreement (the "Subscription Agreement"), which shall conform to the terms and
provisions of this letter agreement and, to the extent not inconsistent
therewith, shall contain substantially the same covenants, conditions to the
parties' obligations, indemnities, representations and warranties and other
applicable provisions of any subscription agreement or understanding entered
into by El Sitio and any equity investor in connection with the Private
Placement. The Subscription Agreement shall be executed by the parties no later
than the Closing.

            5. Other Agreements. In connection with the sale an purchase of
Shares, El Sitio and TVA agree to the following undertakings (the definitive
terms of which shall be incorporated into the Subscription Agreement or an
ancillary agreement).

            (a) Barter Arrangement. For a three-year period after the Closing,
El Sitio will provide TVA with advertising space on El Sitio's internet site
with a value equivalent to US$500,000 per year and TVA will provide El Sitio
with advertising time on any of TVA's television channels with a value
equivalent to US$500,000 per year. The amount of such advertising space or time,
as the case may be, shall be determined based on the rates charged to
similarly-situated clients of the respective party at the time. Any advertising
space received by TVA hereunder may be used by TVA or any of TVA's current or
future clients, provided that

<PAGE>
                                                                              4.


TVA may not grant use of such space (i) to more than five of TVA's clients in
any given year and (ii) to any TVA client to which it is granted such space in
the preceding year. Any advertising time received by El Sitio pursuant to this
paragraph 5(a) may be used by El Sitio alone or in conjunction with up to a
maximum of two sponsors of El Sitio per airing. El Sitio may not sell or
transfer such advertising time to third parties.

            (b) Promotional Event. In consideration for the other agreements
provided herein, TVA agrees to assist El Sitio in organizing and holding an
event at a location in Mexico City to be selected by El Sitio, to which TVA will
invite its advertising clients, for the purpose of promoting El Sitio and
selling advertising space on El Sitio's internet site. TVA will not bear any
cost or expense associated with such event, although TVA agrees to use its
reasonable efforts to reduce costs as described in paragraph 3. All use of TVA's
name in connection with such event is subject to the prior consent of TVA, which
consent shall not be unreasonably withheld.

            (c) Commissions. El Sitio agrees to pay to TVA a commission upon the
consummation by TVA of any sale of advertising space on El Sitio's internet
site, including, without limitation, additional sales made to repeat clients
during the three-year period after the Closing. El Sitio will be entitled to
give its prior consent (not to be unreasonably withheld) as to the form of any
sales proposal used by TVA and the identity of a potential client. The amount of
such commission shall be a percentage of the contract value of each sale made,
determined as follows: (i) 15% for sales with a contract value equal to less
than US$40,000; (ii) 30% for sales with a contract value between US$400,001 and
US$80,000; and (iii) 50% for sales with a contract greater than US$80,000. In
the event that any amount of tax is required to be withheld in respect of any
payments made by El Sitio hereunder, El Sitio shall be responsible for the
deduction and payment to any tax authority of any such taxes and shall increase
the amount of the payment to TVA by such additional amounts as are necessary so
that the amount actually received by TVA after the withholding and payments of
such taxes (including in respect of such additional amounts) is equal to the
payment due hereunder; provided that no such additional amounts shall be payable
in respect of any taxes imposed by Mexico on the net income of TVA or taxes
imposed by reason of any connection between TVA and a taxing jurisdiction other
than

                                                                              5.


entering into or enforcing its rights under this letter agreement or receiving
payment hereunder. Commissions shall be payable within 15 days following the
receipt of payment for a sale by El Sitio.

            6. Conditions to Closing. The closing of transactions contemplated
hereunder (the "Closing") shall occur concurrently with the consummation of the
Private Placement if the following conditions are met:

            (i) consummation of the Private Placement with an aggregate
            investment of not less than US$15,000,000;

            (ii) execution of the Subscription Agreement and, if applicable, any
            ancillary agreements, in each case, in a form satisfactory to TVA in
            its sole discretion;

            (iii) TVA's satisfaction, in its sole discretion, with the results
            of its legal, accounting, tax and business due diligence review of
            El Sitio, its subsidiaries, and any of its affiliates, including,
            without limitation, the operations, business, assets, liabilities
            and prospects of such entities or persons;

            (iv) the absence of any material adverse change in the condition
            (financial or otherwise), results of operations, assets,
            liabilities, businesses, properties or prospects of El Sitio, any of
            its subsidiaries or any of its affiliates after the date of this
            letter agreement; and

            (v) the receipt of all necessary regulatory, governmental,
            shareholders, board of directors and third party approvals, waivers
            and comments (El Sitio hereby representing that it has or will
            obtain the same prior to the Closing).

expenses, damages, claims or proceedings (including legal fees and expenses)
which any of them may pay, incur or be subject to, arising out of or relating to
the Private Placement (whether or not consummated). El Sitio will be not liable
under the foregoing indemnification provision for any expense of TVA referred to

TVA's bad faith or gross negligence.

                           Dated as of August 31, 1999

<PAGE>

            THIS SUBSCRIPTION AGREEMENT, dated as of this 31st day of August.
1999 (this "Agreement"), by and between El Sitio International Corporation, a
corporation organized and existing under the laws of the British Virgin Islands
(the "Company"), and TV Azteca, S.A. de C.V., a corporation organized and
existing under the laws of Mexico (the "Purchaser").

                              W I T N E S S E T H:

            WHEREAS, the Company desires to issue to the Purchaser, and the
Purchaser desires to purchase from the Company, Shares (as such term is defined
below) in exchange for the Purchaser providing the Company television
advertising time; and

            WHEREAS, certain terms used in this Agreement are defined in Section
6.1 hereof;

            NOW, THEREFORE, in consideration of the promises and mutual
covenants and agreements hereinafter contained, the parties hereto agree as
follows:

      1. Sale and Purchase of Securities.

            1.1 Sale and Purchase of Shares. Subject to the terms and conditions
of this Agreement, the Company shall issue, sell and deliver to the Purchaser,
and the Purchaser shall purchase from the Company 355,478 shares of Class A
Preferred Stock, par value $1.00 per share, of the Company ("Shares").

      2. Purchase Price.

            2.1 Amount of Consideration. The Purchaser agrees to provide the
Company with television advertising time worth US$3,500,000 over a period of
three (3) years, beginning on July 2, 1999, on the Purchaser's television
channels (which amounts shall be based on rates actually charged to
similarly-situated clients of the Purchaser at the time) as set forth on
Schedule A. For purposes of calculating the number of Shares to be issued
pursuant to this Agreement, the value of the advertising time provided by the
Purchaser shall be the net present value of such advertising time, which has
been calculated by applying an annual discount rate of 30% and equals
US$2,489,010.

            2.2 Additional Consideration. The Purchaser agrees to use reasonable
efforts to enter into barter arrangements with third parties to reduce the
Company's cash infrastructure and promotional costs related to office space and
other overhead expenses. Any cash savings for the Company obtained by the
Purchaser through such arrangements (as mutually agreed in good faith by the
parties hereto) shall be treated as "Additional Consideration" for the purchase
of Shares. Within 15 days after realizing any such cash savings, the Company
agrees to issue Shares in an amount equal to (x) such Additional Consideration

ARTICLE 2. Registration Rights

            2.1 Demand Registration.

            (a) Upon notice to the Corporation from Stockholder(s) holding in
the aggregate $15.0 million or more of the Restricted Shares (or Preferred
Shares which are convertible into Restricted Shares), such Stockholders (the
"Requesting Stockholders") shall have the right to request in writing a
registration of such shares of Stock that are (or which would be upon
conversion) Restricted Shares. Such request (a "Demand Request") by the
Requesting Stockholders shall (i) specify the number of Restricted Shares which
each Requesting Stockholder intends to sell or dispose of, and (ii) state the
intended method or methods by which the Requesting Stockholder intends to sell
or dispose of such Restricted Shares. Upon receipt of a Demand Request pursuant
to this Section 2.1, the Corporation shall (as requested) (i) cause to be filed,
within the later of (x) ninety (90) days of the date of delivery to the
Corporation of the Demand Request, or (y) one hundred eighty (180) days after
the effectiveness of the most recently filed registration statement by the
Corporation, a registration statement covering such Restricted Shares which the
Corporation has been so requested to register, providing for the registration
under the Securities Act of such Restricted Shares to the extent necessary to
permit the disposition of such Restricted Shares so to be registered in
accordance with the intended method of distribution specified in such Demand
Request, provided, that the Corporation may delay making such filing or taking
such action by not more than one hundred twenty (120) days if the Corporation,
prior to the time it would otherwise have been required to file such
registration statement or take such action, determines in good faith that the
filing of such registration statement or the taking of such action would require
the disclosure of material, non-public information that, in the reasonable
judgment of the Corporation, would be detrimental to the Corporation if so
disclosed (and a delay would be likely to reduce the detrimental effect of such
disclosure or obviate the need for such disclosure to be made, or would
otherwise adversely affect a financing, acquisition, disposition, merger or
other material transaction), (ii) shall use its


                                       2
<PAGE>

best efforts to have such registration statement declared effective by the
Commission as soon as practicable thereafter, and (iii) refrain from filing any
other registration statements with respect to any other securities of the
Corporation until such date which is one hundred eighty (180) days following
effectiveness of the registration statement filed in response to the Demand
Request. Subject to any existing written agreement between the Corporation and
Bear, Stearns & Co. Inc., the underwriter shall be selected by the Requesting
Stockholders and shall be reasonably acceptable to the Corporation for any
registration pursuant to this Section 2.1.

            (b) In the event that the Corporation is required to file a
registration statement covering any Restricted Shares of any Requesting
Stockholder(s) pursuant to Section 2.1(a) above, the Corporation shall be
permitted to include newly-issued securities ("Piggyback Securities") in such
registration. Notwithstanding the foregoing, if the managing underwriter of such
proposed registration determines and advises in writing that the inclusion of
all Piggyback Securities proposed to be included in the underwritten public
offering would interfere with the successful marketing of the Requesting
Stockholders' Restricted Shares, then the Corporation shall not be permitted to
include any Piggyback Securities in excess of the amount, if any, of Piggyback
Securities which the managing underwriter of such underwritten offering shall
reasonably and in good faith agree in writing to include in such offering in
excess of any amount to be registered for the Requesting Stockholder(s). The
Piggyback Securities that are excluded from the underwritten public offering
pursuant to the preceding sentence shall be withheld from the market by the
Corporation for a period, not to exceed 180 days from the closing of such
underwritten public offering, that the managing underwriter determines is
necessary in order to effect such underwritten public offering.

            (c) The Corporation shall not be required to comply with more than
four (4) Demand Requests, at least one (1) of which shall be reserved for
IAMP(El Sitio) Investments Ltd. (and its affiliates) and at least one (1) of
which shall be reserved for the Initial Stockholders.

            2.2 Piggyback Registration.

            (a) Each time that the Corporation proposes for any reason to
register any of its Stock under the Securities Act (a "Proposed Registration"),
other than pursuant to a registration statement on Form F-4 or Form F-8 or
similar or successor forms, the Corporation shall promptly give written notice
of such Proposed Registration to the holders of the Restricted Shares (which
notice shall be given not less than thirty (30) days prior to the expected
effective date of the Corporation's registration statement) and shall offer such
holders the right to request inclusion of any of such holder's Restricted Shares
in the Proposed Registration. No registration pursuant to this Section 2.2 shall
relieve the Corporation of its obligation to register Restricted Shares pursuant
to Section 2.1.

            (b) Each Stockholder shall have twenty (20) days from the receipt of
such notice to deliver to the Corporation a written request specifying the
number of Restricted Shares such Stockholder intends to sell and such
Stockholder's intended method of disposition. Any Stockholder shall have the
right to withdraw such Stockholder's request for inclusion of such Stockholder's
Restricted Shares in any registration statement pursuant to this Section 2.2 by
giving written notice to the Corporation of such withdrawal. Subject to Section
2.3 below, the Corporation shall include in such registration statement all such
Restricted Shares so requested to


                                       3
<PAGE>

be included therein; provided, however, that the Corporation may at any time
withdraw or cease proceeding with any such Proposed Registration if it shall at
the same time withdraw or cease proceeding with the registration of all other
equity securities originally proposed to be registered.

            (c) In the event that the Proposed Registration by the Corporation
is, in whole or in part, an underwritten public offering of securities of the
Corporation, any request under Section 2.2(b) hereof must specify that the
Restricted Shares be included in the underwriting on the same terms and
conditions as the shares of Stock, if any, otherwise being sold through
underwriters under such registration.

            2.3 Priority on Registrations.

            (a) If the managing underwriter advises the Corporation that the
inclusion of such Restricted Shares would cause a Material Adverse Effect, the
Corporation will be obligated to include in such registration statement, as to
each Stockholder, only a portion of the Restricted Shares such Stockholder has
requested be registered equal to the ratio which such Stockholder's requested
Restricted Shares bears to the total number of Restricted Shares requested to be
included in such registration statement by all Stockholders who have requested
that their Restricted Shares be included in such registration statement, in the
case of Stockholders exercising rights under Section 2.2 hereof. It is
acknowledged by the Stockholders, that pursuant to the foregoing provision, the
securities to be included in such registration shall be allocated (x) if such
registration has been initiated by the Corporation for securities to be offered
by the Corporation, first to the Corporation, second to Stockholders exercising
their piggyback right and third to all others requesting securities to be
included therein and (y) if such registration has been initiated by Requesting
Stockholders requesting a Demand Registration, first to such Requesting
Stockholders, second to the Corporation if it exercises its piggyback right and
third to all others requesting securities to be included therein. If as a result
of the provisions of this Section 2.3(b) any Stockholder shall not be entitled
to include all of its Restricted Shares in a registration that such Stockholder
has requested to be so included, such Stockholder may withdraw such
Stockholder's request to include Restricted Shares in such registration
statement. The Restricted Shares that are excluded from the underwritten public
offering pursuant to the preceding sentence shall be withheld from the market by
the Stockholders for a period, not to exceed 180 days from the closing of such
underwritten public offering, that the managing underwriter determines as
necessary in order to effect such underwritten public offering.

            (b) No Stockholder may participate in any registration statement
hereunder unless such Stockholder completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements, and other documents
reasonably required under the terms of such underwriting arrangements, including
an opinion of its counsel; provided, however, that no such Stockholder shall be
required to make any representations or warranties in connection with any such
registration other than representations and warranties as to (i) such
Stockholder's ownership of its Restricted Shares to be sold or transferred free
and clear of all liens, claims, and encumbrances, (ii) such Stockholder's power
and authority to effect such transfer, and (iii) such matters pertaining to
compliance with securities laws as may be reasonably requested.

            2.4 Registration Procedures. Whenever any Stockholder has requested
that any Restricted Shares be registered pursuant to the provisions of this
Article 2, the Corporation


                                       4
<PAGE>

will use its commercially reasonable efforts to effect the registration and the
sale of such Restricted Shares in accordance with the intended method of
disposition thereof as set forth in the written request, and pursuant thereto
the Corporation shall:

            (a) prepare and file with the Commission registration statement(s)
with respect to such securities on the appropriate forms, and use its best
efforts to cause such registration statement(s) to become and remain effective
in accordance with Section 2.4(b) hereof and in accordance with all laws, rules
and regulations applicable thereto;

            (b) prepare and file with the Commission such amendments and
supplements to such registration statement(s) and the prospectus(es) used in
connection therewith as may be necessary to keep such registration statement(s)
effective until the earlier of (i) the sale of all Restricted Shares covered
thereby or (ii) the date required therefor by the underwriters in the
underwriting agreement, and to comply with the provisions of the Securities Act
with respect to the sale or other disposition of all Restricted Shares covered
by such registration statement(s);

            (c) furnish to each Stockholder participating in such registration
pursuant to Section 2.1 or Section 2.2 (each, a "Participating Stockholder")
such number of copies of any summary prospectus or other prospectus, including a
preliminary prospectus, in conformity with the requirements of the Securities
Act, and such other documents as the Stockholder may reasonably request in order
to facilitate the public sale or other disposition of such Restricted Shares;

            (d) use its best efforts to register or qualify the Restricted
Shares covered by such registration statement(s) under the securities or blue
sky laws of such jurisdictions as the Participating Stockholder shall reasonably
request and do any and all other acts or things which may be necessary or
advisable to enable the Participating Stockholders to consummate the public sale
or other disposition in such jurisdictions of such Restricted Shares; provided,
however, that the Corporation shall not be required to consent to general
service of process for all purposes in any jurisdiction where it is not then
subject to process, qualify to do business as a foreign corporation where it
would not be otherwise required to qualify or submit to liability for state or
local taxes where it is not otherwise liable for such taxes;

            (e) at any time when a prospectus relating thereto covered by such
registration statement(s) is required to be delivered under the Securities Act
within the appropriate period mentioned in Section 2.4(b) hereof, promptly
notify each Stockholder and each underwriter and (if requested by any such
Stockholder) confirm such notice in writing (i) when a prospectus or any
prospectus supplement or post-effective amendment has been filed and, with
respect to a registration statement or any post-effective amendment, when the
same has become effective, (ii) of the issuance by any state securities or other
regulatory authority of any order suspending the qualification or exemption from
qualification of any of the Restricted Shares under state securities or blue sky
laws or the initiation of any proceedings for that purpose, and (iii) 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 in light of the
circumstances then existing and, at the request of any Participating
Stockholder, prepare, file and furnish to such Participating Stockholder a
reasonable number of


                                       5
<PAGE>

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 in the light of the circumstances then
existing;

            (f) if the Corporation has delivered preliminary or final
prospectuses to any Participating Stockholder and after having done so the
prospectus is amended to comply with the requirements of the Securities Act, the
Corporation shall promptly notify such Participating Stockholder and, if
requested, the Participating Stockholder shall immediately cease making offers
of Restricted Shares and return all prospectuses to the Corporation. The
Corporation shall promptly provide the Participating Stockholder with revised
prospectuses and, following receipt of the revised prospectuses, the
Participating Stockholder shall be free to resume making offers of the
Restricted Shares;

            (g) furnish, at the request of the Participating Stockholder on the
date such Restricted Shares are delivered to the underwriters for sale in
connection with a registration pursuant to this Article 2, if such Restricted
Shares are being sold through underwriters, or, if such Restricted Shares are
not being sold through underwriters, on the date that the registration statement
with respect to such Restricted Shares becomes effective, (i) an opinion, dated
such date, of the counsel representing the Corporation for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters, if any, and to
the Participating Stockholders and (ii) a letter dated such date, from the
independent certified public accountants of the Corporation, in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and the Participating Stockholders;

            (h) if any proposed registration effected pursuant to Section 2.1 or
Section 2.2 involves an underwritten public offering, (i) subject to Section
2.1, select a reputable managing underwriter to underwrite such public offering,
(ii) cause all Restricted Shares to be listed for trading on the principal
national securities exchange (including, without limitation, the NASDAQ National
Market System) (as defined in the Securities and Exchange Act of 1934, as
amended) where the Corporation's Stock is listed for trading, and (iii) enter
into (x) an underwriting agreement with the underwriter providing for such
representations, warranties, covenants, conditions and indemnities as may be
requested by the underwriter and (y) a deposit agreement with a depositary, if
applicable, providing for such representations, warranties, covenants,
conditions and indemnities as may be requested by the depositary;

            (i) before filing a registration statement or amendment thereto,
furnish to each Participating Stockholder and its counsel and other
representatives and the underwriters, if any, copies of each such registration
statement or amendment proposed to be filed, which documents shall be made
available on a timely basis for review and comment by the Participating
Stockholders, the underwriters (if any) and their respective representatives;

            (j) make generally available to the Corporation's security holders
an earnings statement satisfying the provisions of Section 11(a) of the
Securities Act, as promptly as


                                       6
<PAGE>

practicable, but in any event no later than forty-five (45) days after the end
of the 12-month period beginning with the first day of the Corporation's first
fiscal quarter commencing after the effective date of a registration statement,
which earnings statement shall cover said 12-month period, and which requirement
will be deemed to be satisfied if the Corporation timely files complete and
accurate information on Forms 20-F and 6-K under the Exchange Act and otherwise
complies with Rule 158 under the Securities Act;

            (k) if requested by the managing underwriter or any Participating
Stockholder, promptly incorporate in a prospectus supplement or post-effective
amendment such information as the managing underwriter or any Participating
Stockholder reasonably requests to be included therein, including, without
limitation, with respect to the Restricted Shares being sold by such
Participating Stockholder, the purchase price being paid therefor by the
underwriters and with respect to any other terms of the underwritten offering of
the Restricted Shares to be sold in such offering, and promptly make all
required filings of such prospectus supplement or post-effective amendment;

            (l) as promptly as practicable after filing with the SEC of any
document which is incorporated by reference into a registration statement (in
the form in which it was incorporated), deliver a copy of each such document to
each Participating Stockholder;

            (m) cooperate with the Participating Stockholders and the managing
underwriter to facilitate the timely preparation and delivery of certificates
(which shall not bear any restrictive legends unless required under applicable
law) representing securities sold under any registration statement (if any), and
enable such securities to be in such denominations and registered in such names
as the managing underwriter or such sellers may request and keep available and
make available to the Corporation's transfer agent prior to the effectiveness of
such registration statement a supply of such certificates;

            (n) promptly make available for inspection by any Participating
Stockholder, any underwriter participating in any disposition pursuant to any
registration statement, and any attorney, accountant or other agent or
representative retained by any such Participating Stockholder or underwriter
(collectively, the "Inspectors"), all financial and other records, pertinent
corporate documents and properties of the Corporation (collectively, the
"Records"), as shall be reasonably necessary to enable them to exercise their
due diligence responsibility, and cause the Corporation's officers, directors
and employees to supply all information requested by any such Inspector in
connection with such registration statement; provided, that, unless the
disclosure of such Records is necessary to avoid or correct a misstatement or
omission in the registration statement or the release of such Records is ordered
pursuant to a subpoena or other order from a court of competent jurisdiction,
the Corporation shall not be required to provide any information under this
subparagraph (n) if (A) the Corporation believes, after consultation with
counsel for the Corporation, that to do so would cause the Corporation to
forfeit an attorney-client privilege that was applicable to such information or
(B) if either (i) the Corporation has requested and been granted from the SEC
confidential treatment of such information contained in any filing with the SEC
of documents provided supplementally or otherwise or (ii) the Corporation
reasonably determines in good faith that such Records are confidential and so
notifies the Inspectors in writing unless prior to furnishing any such
information with respect to (A) or (B) such Participating Stockholder requesting
such information agrees to enter into a


                                       7
<PAGE>

confidentiality agreement in customary form and subject to customary exceptions;
and provided, further, that each Participating Stockholder agrees that it will,
upon learning that disclosure of such Records is sought in a court of competent
jurisdiction, give notice to the Corporation and allow the Corporation at its
expense, to undertake appropriate action and to prevent disclosure of the
Records deemed confidential;

            (o) provide a CUSIP number for the Restricted Shares included in any
registration statement not later than the effective date of such registration
statement;

            (p) cooperate with each Participating Stockholder and each
underwriter participating in the disposition of such Restricted Shares and their
respective counsel in connection with any filings required to be made with the
National Association of Securities Dealers, Inc. ("NASD");

            (q) during the period when the prospectus is required to be
delivered under the Securities Act, promptly file all documents required to be
filed with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the
Exchange Act;

            (r) notify each Participating Stockholder promptly of any request by
the SEC for the amending or supplementing of such registration statement or
prospectus or for additional information;

            (s) prepare and file with the SEC promptly any amendments or
supplements to such registration statement or prospectus which, in the opinion
of counsel for the Corporation or the managing underwriter, is required in
connection with the distribution of the Restricted Shares;

            (t) advise each Participating Stockholder, promptly after it shall
receive notice or obtain knowledge thereof, of the issuance of any stop order by
the SEC suspending the effectiveness of such registration statement or the
initiation or threatening of any proceeding for such purpose and promptly use
its best efforts to prevent the issuance of any stop order or to obtain its
withdrawal at the earliest possible moment if such stop order should be issued;
and

            (u) if the Participating Stockholders so request, to request
acceleration of effectiveness of the registration statement from the Commission,
provided at the time of such request the Corporation does not, in good faith,
believe it is necessary to amend further the registration statement in order to
comply with the provisions of this Section 2.4. If the Corporation wishes to
further amend the registration statement prior to requesting acceleration, it
shall have five (5) business days to so amend prior to requesting acceleration.

            2.5 Suspension of Dispositions. Each Participating Stockholder
agrees that upon receipt of any notice (a "Suspension Notice") from the
Corporation of the happening of any event of the kind described in Section
2.4(e)(iii), such Participating Stockholder will forthwith discontinue
disposition of Restricted Shares until such Participating Stockholder's receipt
of the copies of the supplemented or amended prospectus, or until it is advised
in writing (the "Advice") by the Corporation that the use of the prospectus may
be resumed, and has received copies of any additional or supplemental filings
which are incorporated by reference in the prospectus, and, if so directed by
the Corporation, such Participating Stockholder will deliver to


                                       8
<PAGE>

the Corporation all copies, other than permanent file copies then in such
Participating Stockholder's possession, of the prospectus covering such
Restricted Shares current at the time of receipt of such notice. In the event
the Corporation shall give any such notice, the time period regarding the
effectiveness of registration statements set forth in Section 2.4(b) hereof
shall be extended by the number of days during the period from and including the
date of the giving of the Suspension Notice to and including the date when each
seller of Restricted Shares covered by such registration statement shall have
received the copies of the supplemented or amended prospectus or the Advice. The
Corporation shall use its commercially reasonable efforts and take such actions
as are reasonably necessary to render the Advice as promptly as practicable.

            2.6 Cooperation upon a Registration. The Stockholders and the
Corporation agree that, in connection with any exercise of registration rights
pursuant to this Article 2, the Stockholders will authorize, and will authorize
and direct the Board to take, such actions as are necessary and appropriate to
effectuate such registration. In addition, each Participating Stockholder agrees
to cooperate fully with the Corporation and the underwriters of any underwritten
public offering in the preparation of all documentation necessary or desirable
to effectuate any registration of any Restricted Shares under the Securities Act
pursuant to this Article 2, or registration or qualification of any Restricted
Shares pursuant to Section 2.4(d) hereof. In addition, the Corporation agrees to
cooperate fully with the Participating Stockholders in connection with any such
registration or qualification.

            2.7 Limitations. Notwithstanding anything in this Agreement to the
contrary, if requested in writing by the managing underwriter, if any, of any
underwritten public offering of the Corporation's capital stock pursuant to this
Article 2, each Stockholder agrees not to offer, sell, contract to sell or
otherwise dispose of any shares of capital stock of the Corporation except as
part of such underwritten public offering within thirty (30) days before or one
hundred and eighty (180) days after the effective date of the registration
statement filed with respect to said offering, unless expressly authorized to do
so by the managing underwriter.

            2.8 Expenses. The Corporation shall pay all expenses incurred by the
Corporation in complying with Sections 2.1, 2.2 and 2.4 hereof, including,
without limitation, all registration and filing fees (including all expenses
incident to filing with the NASD), fees and expenses of complying with the
securities or blue sky laws of all such jurisdictions in which the Restricted
Shares are proposed to be offered and sold (including reasonable fees and
disbursements of counsel in connection with blue sky qualification of Restricted
Shares), rating agency fees, printing expenses, messenger and delivery expenses,
the Corporation's internal expenses (including without limitation all salaries
and expenses of its officers and employees performing legal or accounting
duties), fees and expenses incurred in connection with any listing of the
Restricted Shares, fees and expenses of counsel for the Corporation and its
independent certified public accountants (including the expenses of any special
audit or cold comfort letters required by or incident to such performance),
securities act liability insurance (if the Corporation elects to obtain such
insurance) and fees and disbursements of underwriters (to the extent the
Corporation is liable therefor under the terms of any underwriting agreement),
whether or not any registration statement becomes effective; provided, however,
that all underwriting discounts and selling commissions applicable to the
Restricted Shares covered by registrations effected pursuant to Section 2.1 or
Section 2.2 hereof shall be borne by the Participating Stockholders, in
proportion to the number of Restricted Shares sold by each such Participating
Stockholder, and


                                       9
<PAGE>

except as expressly provided in this Section 2.8, in no event shall the
Corporation pay any fees or expenses attributable to any counsel, accountants or
other persons retained or employed by the Participating Stockholders. Further to
the foregoing, the Corporation shall pay all reasonable and customary expenses
incurred by any Participating Stockholder, including, without limitation, all
reasonable expenses and fees of one (1) firm of counsel for all Participating
Stockholders (which shall be selected by a majority (based on the number of
Restricted Securities to be sold) of the Participating Stockholders), plus, to
the extent reasonably necessary, one (1) firm of local counsel for all of the
Participating Stockholders in each state or country where reasonably necessary
(the "Expenses").

            2.9 Indemnification.

            (a) In the event of any registration of any Restricted Shares under
the Securities Act pursuant to this Article 2 or registration or qualification
of any Restricted Shares pursuant to Section 2.4(d) hereof, the Corporation
shall indemnify and hold harmless each Participating Stockholder, each
underwriter of such shares, if any, each broker or any other person acting on
behalf of the Participating Stockholders, each director, officer, employee and
partner of any of the foregoing and each other person, if any, who controls any
of the foregoing persons, within the meaning of the Securities Act (each, an
"Indemnified Person"), against any losses, claims, damages, liabilities or
expenses, joint or several, to which any of the foregoing persons may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of, are related
to, result from or are based upon an untrue statement or alleged untrue
statement of a material fact contained in any registration statement under which
such Restricted Shares were registered under the Securities Act, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereto, or any document incident to registration or qualification of any
Restricted Shares pursuant to Section 2.4(d) hereof, or arise out of, are
related to, result from or are based upon the 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, with respect to any prospectus,
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, or any violation by the Corporation of the
state securities or blue sky laws applicable to the Corporation and relating to
action or inaction required of the Corporation in connection with such
registration or qualification under such state securities or blue sky laws and
the Corporation shall reimburse on demand each Indemnified Person for any legal
or any other costs and expenses reasonably incurred by any of them in connection
with investigating, preparing for, defending or settling any such loss, claim,
damage, liability or action by any governmental agency or body; provided,
however, that the Corporation shall not be liable in any such case to the extent
that any such loss, claim, damage, liability or expense arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in said registration statement, preliminary or final
prospectus or amendment or supplement thereto or any document incident to
registration or qualification of any Restricted Shares pursuant to Section
2.4(d) hereof, in reliance upon and in conformity with written information
furnished to the Corporation by any Participating Stockholder, underwriter,
broker, other person or controlling person specifically for use in the
preparation thereof or arises out of or is based upon the Indemnified Person's
failure to deliver a copy of the registration statement or prospectus or any
amendments or supplements thereto after the Corporation has furnished such
Indemnified Person with a sufficient number of copies of the same; provided
further, that the


                                       10
<PAGE>

Corporation shall not be liable for any settlement made without its prior
written consent, such consent not to be unreasonably withheld.

            (b) Before Restricted Shares shall be included in any registration
pursuant to this Article 2, each Participating Stockholder will furnish to the
Corporation in writing such information and affidavits as the Corporation
reasonably requests for use in connection with any registration statement and
prospectus, and each such Participating Stockholder and any underwriter acting
on its behalf shall have agreed to indemnify and hold harmless (in the same
manner and to the same extent as set forth in paragraph (a) above) the
Corporation, each director of the Corporation, each officer of the Corporation
who signs such registration statement, every other Participating Stockholder and
any person who controls the Corporation within the meaning of the Securities
Act, with respect to any untrue statement or omission from such registration
statement, any preliminary prospectus or final prospectus contained therein, or
any amendment or supplement thereto, if such untrue statement or omission was
made in reliance upon and in conformity with written information furnished to
the Corporation by the Participating Stockholder or such underwriter for use in
the preparation of such registration statement, preliminary prospectus, final
prospectus or amendment or supplement; provided, however, that the maximum
amount of liability in respect of such indemnification shall be limited to an
amount equal to the net proceeds actually received by such Participating
Stockholder from the sale of Restricted Shares effected pursuant to such
registration.

            (c) Promptly after receipt by an indemnified party of notice of the
commencement of any action involving a claim referred to in Section 2.9(a) or
(b) hereof, such indemnified party will, if a claim in respect thereof is to be
made against the indemnifying party under this Section 2.9, give prompt written
notice to the latter of the commencement of such action (provided that the
failure to give such notice shall not limit the rights of such indemnified party
unless and to the extent such failure is prejudicial to its ability to defend
such action). In case any such action is brought against an indemnified party,
the indemnifying party will be entitled to participate in and to assume the
defense thereof, jointly with any other indemnifying party similarly notified to
the extent that it may wish, with counsel reasonably satisfactory to such
indemnified party, and, after notice to such indemnified party from the
indemnifying party of its election to assume the defense thereof; provided,
however, that, if any indemnified party shall have reasonably concluded that
there may be one or more legal defenses available to such indemnified party
which are different from, in conflict with or additional to those available to
the indemnifying party, or that such claim or litigation involves or could
reasonably be expected to have an effect upon matters beyond the scope of the
indemnity agreement provided in this Section 2.9, or if the indemnifying party
fails to take diligent action to defend such claim within twenty (20) days
following notice thereof from the indemnified party, the indemnifying party
shall not have the right to assume the defense of such action on behalf of such
indemnified party, or that such claim or litigation involves or could have an
effect upon matters beyond the scope of the indemnity agreement provided in this
Section 2.9, or if the indemnifying party fails to take diligent action to
defend such claim within twenty (20) days following notice thereof from the
indemnified party, and such indemnifying party shall reimburse such indemnified
party and any person controlling such indemnified party for the fees and
expenses of counsel retained by the indemnified party which are reasonably
related to the matters covered by the indemnity agreement provided in this
Section 2.9. If the indemnifying party does assume its own defense, from such
time the indemnified party shall bear the expenses of its own separate counsel.
If such


                                       11
<PAGE>

defense is not assumed by the indemnifying party as permitted hereunder, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without its written consent, which consent shall not be
unreasonably withheld. If such defense is assumed by the indemnifying party
pursuant to the provisions hereof, such indemnifying party shall not make any
settlement of the applicable claim indemnified against hereunder without the
written consent of the indemnified party or parties, which consent shall not be
unreasonably withheld. An indemnifying party that is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party and any other such indemnified party with respect to such
claim, unless in the reasonable judgment of any indemnified party, a conflict of
interest may exist between such indemnified party with respect to such claim, in
which event the indemnifying party shall be obligated to pay the reasonable fees
and disbursements of such additional counsel or counsels.

            (d) In order to provide for just and equitable contribution to joint
liability under the Securities Act in any case in which an Indemnified Person
makes a claim for indemnification pursuant to this Section 2.9, but it is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced
notwithstanding the fact that this Section 2.9 provides for indemnification in
such case, then the Corporation and the Participating Stockholder will
contribute to the aggregate losses, claims, damages or liabilities to which they
may be subject as is appropriate to reflect, as between the indemnifying party,
on the one hand, and the indemnified party on the other hand, the relative fault
of the indemnifying party, on the one hand, and the indemnified party, on the
other hand, in connection with the statements or omissions which resulted in
such losses, claims, damages or liabilities, it being understood that the
parties acknowledge that the overriding equitable consideration to be given
effect in connection with this provision is the ability of one party or the
other to correct the statement or omission which resulted in such losses,
claims, damages or liabilities, and that it would not be just and equitable if
contribution pursuant hereto were to be determined by pro rata allocation or by
any other method of allocation which does not take into consideration the
foregoing equitable considerations. Notwithstanding the foregoing, (i) the
Participating Stockholder will not be required to contribute any amount in
excess of the proceeds to it of all Restricted Shares sold by it pursuant to
such registration statement, (ii) no underwriter shall be required to contribute
any amount in excess of the proceeds to it from the offering pursuant to such
registration statement, and (iii) no person or entity guilty of fraudulent
misrepresentation, within the meaning of Section 11(f) of the Securities Act,
shall be entitled to contribution from any person or entity who is not guilty of
such fraudulent misrepresentation. If indemnification is available under this
Section 2.9, the indemnifying parties shall indemnify each indemnified party to
the full extent provided in Section 2.9(a) and 2.9(b) without regard to the
relative fault of said indemnifying party or indemnified party or any other
equitable consideration provided for in this Section 2.9(d).

            (e) Notwithstanding any of the foregoing, if in connection with an
underwritten public offering of any Restricted Shares, the Corporation, the
Participating Stockholder and the underwriters enter into an underwriting or
purchase agreement relating to such offering which contains provisions covering
indemnification among the parties, the


                                       12
<PAGE>

indemnification provided thereunder shall be in addition to (and not in lieu of)
the indemnification provided to the Stockholders hereunder.

            (f) The indemnification and contribution required by this Section
2.9 shall be made by periodic payment of the amount thereof during the course of
the investigation or defense, as and when bills are received or expense, loss,
damage or liability is incurred; provided, that if a court of competent
jurisdiction finally determines that any Indemnified Person which has received
payments hereunder does not have an indemnification right under Section 2.9 for
any reason, then such Indemnified Person shall within five (5) days of such
final determination, refund all amounts received hereunder to the Corporation.

            (g) The indemnification and contribution provided for hereunder will
remain in full force and effect regardless of any investigation made by or on
behalf of any Indemnified Person and will survive the transfer of securities.

ARTICLE 3. Miscellaneous

            3.1 Notices. Any and all notices, designations, consents, offers,
acceptances, or any other communication required or permitted to be given by any
provision of this Agreement shall be deemed to be sufficient if contained in a
written instrument delivered in person or duly sent by registered mail or
telecopied with acknowledgment of receipt sent by telecopier, registered mail or
delivered in person, as the case may be, to such party at the address or
telecopier number, as the case may be, set forth on the signature pages hereto
or to such other address or telecopier number, as the case may be, as such party
may from time to time designate in writing to the other parties. All such
notices, requests, consents and other communications shall be deemed to have
been received: (a) in the case of personal delivery or registered mail, on the
date of receipt; or (b) in the case of telecopying, on the date of
acknowledgment thereof.

            3.2 Amendment and Waiver. No change or modification of, or waiver of
compliance with, this Agreement shall be valid unless the same shall be in
writing and signed by all of the parties hereto.

            3.3 Termination. This Agreement may be terminated at any time by an
instrument in writing signed by all of the parties hereto. This Agreement shall
terminate automatically as to any Stockholder which transfers all of its
Restricted Shares. Unless sooner terminated, this Agreement shall terminate
eight (8) years from the date hereof, unless, at any time within one (1) year
prior to such date, all of the parties extend its duration for as many
additional periods, each not to exceed eight (8) years, as they may desire.

            3.4 No Waiver. No failure or delay on the part of the Stockholders
or any of them in exercising any right, between the Corporation and the
Stockholders or any of them shall operate as a waiver thereof nor shall any
single or partial exercise of any right, power or privilege hereunder preclude
the simultaneous or later exercise of any other right, power or privilege. The
rights and remedies herein expressly provided are cumulative and not exclusive
of any rights or remedies which the Stockholders or any of them would otherwise
have. No notice to or demand on the Corporation in any case shall entitle the
Corporation to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of


                                       13
<PAGE>

the Stockholders or any of them to take any other or further action in any
circumstances without notice or demand.

            3.5 Specific Performance. Each party to this Agreement acknowledges
that the other parties will suffer irreparable injury in the event of any breach
of any provision of this Agreement and that therefore the remedy at law for any
breach or threatened breach of any such provision of this Agreement will be
inadequate. Accordingly, upon a breach or threatened breach of any such
provision of this Agreement by any party hereto, the other parties shall, in
addition and without prejudice to any of the rights and remedies they may have,
be entitled as a matter of right, without proof of actual damages, to seek
specific performance of such provisions of this Agreement and to such other
injunctive or equitable relief to enforce, or prevent any violations (whether
anticipatory, continuing or future) of, such provisions of this Agreement.

            3.6 Counterparts and Headings. This Agreement may be executed in two
or more counterparts, each of which shall be deemed to be an original, but all
of which together shall constitute one and the same instrument. All headings and
any cover page or table of contents are inserted for convenience or reference
only and shall not affect its meaning or interpretation.

            3.7 Nouns and Pronouns. Whenever the context may require, any
pronouns used herein shall include the corresponding masculine, feminine or
neuter forms, and the singular form of nouns and pronouns shall include the
plural and vice-versa.

            3.8 Expenses. Except as provided in Section 2.8 hereto, each of the
parties to this Agreement shall bear its own expenses, including, without
limitation, the fees and disbursements of its respective counsel, in connection
with the negotiation and execution of this Agreement and the consummation of the
transactions contemplated hereby.

            3.9 Governing Law. This Agreement will be governed by, and construed
and enforced in accordance with, the laws of the State of New York, U.S.A.,
without regard to its conflict of law rules.

            3.10 Submission to Jurisdiction; Consent to Service of Process.

            (a) The parties hereto hereby irrevocably submit to the
non-exclusive jurisdiction of any federal or state court located within the
Borough of Manhattan, State of New York over any dispute arising out of or
relating to this Agreement or any of the transactions contemplated hereby and
each party hereby irrevocably agrees that all claims in respect of such dispute
or any suit, action or proceeding related thereto may be heard and determined in
such courts. The parties hereby irrevocably waive, to the fullest extent
permitted by applicable law, any objection which they may now or hereafter have
to the laying of venue of any such dispute brought in such court or any defense
of inconvenient forum for the maintenance of such dispute. Each of the parties
hereto agrees that a judgment in any such dispute may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

            (b) Each of the parties hereto hereby consents to process being
served by any party to this Agreement in any suit, action or proceeding by the
mailing of a copy thereof in accordance with the provisions of Section 3.1
hereof.

            3.11 Successors and Assigns. This Agreement shall be binding upon
and shall inure to the benefit of the Corporation and its successors, and each
of the Stockholders and their respective executors, administrators and personal
representatives and heirs and their successors and assigns.

            3.12 Severability. In the event that any provision of this Agreement
becomes or is declared by a court of competent jurisdiction to be illegal,
invalid or unenforceable, the remaining provisions hereof shall nevertheless
continue in full force and effect as though the illegal, invalid or
unenforceable provisions were not a part hereof, and the parties shall exert
their best efforts to amend this Agreement to include a provision which is
legal, valid and enforceable and which carries out the original intent of the
parties.

            3.13 Complete Agreement. This Agreement contains the entire
agreement among the parties with respect to the subject matter hereof and
supersedes all prior and contemporaneous arrangements or understandings, whether
written or oral, between or among any of the parties hereto, with respect to the
subject matter hereof.

            3.14 Further Assurances. Each of the parties to this Agreement
agrees to execute such other documents and take such other action as may be
reasonably necessary to implement and carry out the intent of this agreement.

            3.15 Confidentiality. Each Stockholder covenants and agrees to treat
any non-public information provided to it by the Corporation concerning the
business and finances of the Corporation ("Corporate Information") as
confidential and agrees further that it will not use, exploit, reproduce,
disclose or provide Corporate Information to any third party (other than any
agents of the Stockholder who are bound by substantially similar obligations of
confidentiality) on its own behalf or otherwise, except with the consent of the
Corporation or as required by law, legal process or any federal or state
regulatory body having jurisdiction over such Stockholder. The provisions of
this Section 3.15 shall not apply to any information which:

            (a) was within the public domain prior to the time of disclosure of
Corporate Information to the Stockholder or which comes into the public domain
other than as a result of a breach by the Stockholder of this Section 3.15;

            (b) was in the possession of the Stockholder (or any of its
officers, directors, employees, agents, principals, or affiliates) before the
Stockholder received the Corporate Information;

            (c) was rightfully acquired by the Stockholder from a third party
without, to the knowledge of the Stockholder, any restriction or any obligation
of confidentiality; or

            (d) was independently developed by the Stockholder without any use
or reference to the Corporate Information.

            The provisions of this Section 3.15 shall survive the termination of
this Agreement, either in whole or as to any Stockholder, for a period of two
(2) years.


                                       15

3.16. Failure to Execute. Failure of any party to execute this Agreement renders
this Agreement void as to the non-executing party, but such Agreement shall be
valid and binding as to all other parties that execute such Agreement.

discretion shall deem relevant. Subject to the provisions of the Plan, the
Committee shall have plenary authority to construe and interpret the Plan and
the Agreements, to prescribe, amend and rescind rules and regulations relating

Individual shall be granted Options or Rights totally more than 15% of the total
number of Shares issuable under the Plan

      5. Stock Subject to the Plan

      5.1. Subject to adjustment as provided in Article 9, the number of Shares
that may be issued under the Plan is 620,000.

      5.2 If an Option or right expires or terminates for any reason (other than

been fully exercised, the unissued Shares which had been subject to such Option
shall become available for the grant of additional Options or Rights.

      5.3 Upon exercise of a Right (regardless of whether the Right is settled
in cash or Shares), the number of Shares with respect to which the Right is
exercised shall be charged against the number of Shares issuable under the Plan
and shall not become available for the grant of other Awards.

6. Options

      6.1 Options granted under the Plan shall be either Incentive Stock Options
or Nonstatutory Stock Options, as designated by the Committee. Each Option
granted under the Plan shall be clearly identified either as an Incentive Stock
Option or a Nonstatutory Stock Option and shall be evidenced by an Agreement
that specifies the terms and conditions of the grant. Options granted to
Eligible Individuals shall be subject to the terms and conditions set forth in
this Article 6 and such other terms and conditions not inconsistent with this
Plan as the Committee may specify.

      6.2 The Option Period for Options granted to Eligible Individuals shall be
determined by the Committee and specifically set forth in the Agreement,
provided, however, that an Option shall not be exercisable after ten years (five
years in the case of an Incentive Stock Option granted to a Ten-Percent
Stockholder) from its Date of Grant.

7. Rights

      7.1 Rights granted under the Plan shall be evidenced by an Agreement
specifying the terms and conditions of the grant.

<PAGE>

      7.2 A Right may be granted under the Plan:

      (a) in connection with, and at the same time as, the grant of an Option
under the Plan;

      (b) by amendment of an outstanding Option granted under the Plan; or

      (c) independently of any Option granted under the Plan.

      7.3 A right granted under Section 7.2(a) or Section 7.2(b) of this Plan is
a Related Right. A Related Right may, in the Committee's discretion, apply to
all or any portion of the Shares subject to the Related Option.

      7.4 A Right may be exercised in whole or in part as provided in the
applicable Agreement, and, subject to the terms of the Agreement, entitles an
Optionee to receive, without payment to the Company (but subject to required tax
withholding), either cash or that number of Shares (equal to the highest whole
number of Shares), or a combination thereof, in an amount or having a fair
market value determined as of the Date of Exercise not to exceed the number of
Shares subject to the portion of the Right exercised multiplied by an amount
equal to the excess of (i) the Fair Market Value on the Date of Exercise of the
Right over (ii) either (A) the Fair Market Value on the Date of Grant of the
Right if it is not a Related Right, or (B) the Option Price as provided in the
Related Option if the Right is a Related Right.

      7.5 The Right Period shall be determined by the Committee and specifically
set forth in the applicable Agreement, subject to the following conditions:

      (a) a Right will expire no later than the earlier of (1) ten years from
the Date of Grant, or (2) in the case of a Related Right, the expiration of the
Related Option;

      (b) a Right may be exercised only when the Fair Market Value on the Date
of Exercise exceeds either (1) the Fair Market Value on the Date of Grant of the
Right if it is not a Related Right, or (2) the Option Price of the Related
Option if the Right is a Related Right; and

      (c) a Right that is a Related Right to an Incentive Stock Option may be
exercised only when and to the extent the Related Option is exercisable.

      7.6 The exercise, in whole or in part, of a Related Right shall cause a
reduction in the number of Shares subject to the Related Option equal to the
number of Shares with respect to which the Related Right is exercised.
Similarly,

<PAGE>

the exercise, in whole or in part, of a Related Option shall cause a
reduction in the number of Shares subject to the Related Right equal to the
number of Shares with respect to which the Related Option is exercised.

8. Exercise of Options and Rights

      8.1 An Option or Right may, subject to the terms of the applicable
Agreement under which it is granted. be exercised in whole or in part by the
delivery to the Company of written notice of the exercise, in such form as the
Committee may prescribe, accompanied, in the case of an Option, by full payment
of the Option Price for the Shares with respect to which the Option is exercised
as provided in Section 8.2 hereof.

      8.2 Payment of the aggregate Option Price for the Shares with respect to
which an Option is being exercised shall be made in cash; provided, however,
that the Committee, in its sole discretion, may provide in an Agreement that
part or all of such payment may be made by the Optionee in one or more of the
following manners: (a) by delivery (including constructive delivery) to the
Company of Shares valued at Fair Market Value on Date of Exercise; (b) by
delivery on a form prescribed by the Committee of a properly executed exercise
notice and irrevocable instructions to a registered securities broker approved
by the Committee to sell Shares and promptly deliver cash to the Company; (c) by
delivery of a promissory note as provided in Section 8.3 hereof, or (d) by
surrender to the Company of an Option (or a portion thereof) that has become
exercisible and the receipt from the Company upon such surrender, without any
payment to the Company (other than required tax withholding amounts), of (x)
that number of Shares (equal to the highest whole number of Shares) having an
aggregate Fair Market Value as of the date of surrender equal to that number of
Shares subject to the Option (or portion thereof) being surrendered multiplied
by an amount equal to the excess of (i) the Fair Market Value on the date of
surrender over (ii) the Option Price, plus (y) an amount of cash equal to the
Fair Market Value of any fractional Share to which the Optionee would be
entitled but for the parenthetical in clause (x) above relating to whole number
of Shares.

      8.3 To the extent provided in an Agreement and permitted by applicable
law, the Committee may accept as payment of the Option Price a promissory note
executed by the Optionee evidencing his or her obligation to make future cash
payment thereof; provided, however, that in no event may the Committee accept a
promissory note for an amount in excess of the difference between the aggregate
Option Price and the par value of the Shares. Promissory notes made pursuant to
this Section 8.3 shall be payable upon such terms as may be determined by the
Committee, shall be secured by a pledge of the Shares received upon exercise of
the Option and shall bear interest at a rate fixed by the

<PAGE>

Committee.

9. Restrictions on Transfer

      Options and Rights shall not be transferable other than by will or the
laws of descent and distribution. An Option or Right may be exercised during the
Optionee's lifetime only by the Optionee or, in the event of his or her legal
disability, by his or her legal representative. The Shares acquired pursuant to
the Plan shall be subject to such restrictions and agreements regarding sale,
assignment, encumbrances, or other transfers or dispositions thereof (i) as are
in effect among the stockholders of the Company at the time such Shares are
acquired, (ii) as the Committee shall deem appropriate and (iii) as are required
by applicable law.

10. Capital Adjustments

      In the event of any change in the outstanding Common Stock by reason of
any stock dividend, split-up (or reverse stock split), recapitalization,
reclassifcation, reorganization, reincorporation, combination or exchange of
shares, merger, consolidation, liquidation or similar change incorporate
structure, the Committee may, in its discretion, proved for a substitution for
or adjustment in (i) the number and class of Shares subject to outstanding
Options or Rights, (ii) the Option Price of outstanding Options the base price
upon which payments under Rights that are not Related Rights are determined, and
(iii) the aggregate number and class of Shares that may be issued under the
Plan.

11. Termination or Amendment

      The Board may amend, alter, suspend or terminate the Plan in any respect
at any time; provided, however, that after the Plan has been approved by the
stockholders of the Company, no amendment, alteration, suspension or termination
of the Plan shall be made by the Board without approval of (i) the Company's
stockholders to the extent stockholder approval is required by applicable law or
regulations and (ii) each affected Optionee if such amendment, alteration,
suspension or termination would adversely affect his or her rights or
obligations under any Option granted prior to the date of such amendment,
alteration, suspension or termination. No Option may be granted nor any Shares
issued under the Plan during any suspension or after termination of the Plan.

12. Modification, Extension and Renewal of Options; Substituted Options

      12.1 Subject to the terms and conditions of the Plan, the Committee may
modify, extend or renew the terms of any outstanding Options and Rights, or

<PAGE>

accept the surrender of outstanding Options and Rights granted under the Plan or
options and stock appreciation rights granted under any other plan of the
Company or an Affiliate (to the extent not theretofore exercised) and authorize
the granting of new Options and Rights in substitution therefor (to the extent
not theretofore exercised). Any such substituted Options or Rights may specify a
lower exercise price than the surrendered options and stock appreciation rights,
a longer term than the surrendered options and stock appreciation rights, or
have any other provisions that are authorized by the Plan. Notwithstanding the
foregoing, however, no modification of an Option or Right shall, without the
consent of the Optionee, alter or impair any of the Optionee's rights or
obligations under such Option.

      12.2 Anything contained herein to the contrary notwithstanding, Options
and Rights may, at the discretion of the Committee, be granted under the Plan in
substitution for stock appreciation rights and options to purchase shares of
capital stock of another corporation which is merged into, consolidated with, or
all or a substantial portion of the property or stock of which is acquired by,
the Company or one of its Affiliates. The terms and conditions of the substitute
Options so granted may vary from the terms and conditions set forth in this Plan
to such extent as the Committee may deem appropriate in order to conform in
whole or part, to the provisions of the options and stock appreciation rights in
substitution for which they are granted.

      13. Effectiveness of the Plan

      The Plan and any amendment thereto shall be effective on the date on which
it is adopted by the Board, provided that any such adoption requiring
stockholder approval is subject to approval by vote of the stockholders of the
Company within 12 months after such adoption by the Board. Options and Rights
may be granted prior to stockholder approval of the Plan, and the date on which
any such Option or Right is granted shall be the Date of Grant for all purposes
provided that (a) each such Option or Right shall be subject to stockholders
approval of the Plan, (b) no Option or Right may be exercised prior to such
stockholder approval, and (c) any such Option or Right shall be void ab initio
if such stockholder approval is not obtained.

14. Witholding

      The Company's obligation to deliver Shares or pay any amount pursuant to
the terms of any Option or Right shall be subject to the satisfaction of
applicable federal, state and local tax and social security, if applicable,
withholding requirements. To the extent provided in the applicable Agreement and
in accordance with rules prescribed by the Committee, an Optionee may

<PAGE>

satisfy any such withholding tax obligation by any of the following means or by
a combination of such means: (i) tendering a cash payment, (ii) authorizing the
Company to withhold Shares otherwise issuable to the Optionee, or (iii)
delivering to the Company already owned and unencumbered Shares.

15. Term of the Plan

      Unless sooner terminated by the Board pursuant to Article 11, the Plan
shall terminate on December 1, 2008 and no Options or Rights may be granted
after such date. The termination of the Plan shall not affect the validity of
any Option or Right outstanding on the date of termination.

16. Indemnification of Committee

      In addition to such other rights of indemnification as they may have as
Directors or as members of the Committee, the members of the Committee shall be
indemnified by the Company against the reasonable expenses, including attorneys'
fees, actually and reasonably incurred in connection with the defense of any
action, suit or proceeding, or in connection with any appeal therein, to which
they or any of them may be a party by reason of any action taken or failure to
act under or in connection with the Plan or any Option or Right granted
hereunder, and against all amounts reasonably paid by them in settlement hereof
or paid by them in satisfaction of a judgment in any such action, suit or
proceeding, if such members acted in good faith and in a manner which they
believed to be in, and not opposed to, the best interest of the Company.

17. General Provisions

      17.1 The establishment of the Plan shall not confer upon any Eligible

contained in the Plan, this Agreement or the Securities Act or to comply with
other applicable laws.

      8. Rights as Stockholder. The Optionee shall have no rights as a
stockholder with respect to any Covered Shares until and unless a certificate or
certificates representing such shares are issued to the Optionee pursuant to

dividends or other rights for which the record date is prior to the issuance of
such certificate or certificates.

                        (i) The termination by El Sitio of this Agreement for
                  any reason (including, but not limited to, El Sitio's election
                  not to renew this Agreement pursuant to Paragraph 2(a) hereof)
                  other than "cause" (as defined in Paragraph 6 herein); or

                        (ii) Executive's termination of this Agreement, pursuant
                  to:

                                    A. a material change by El Sitio of the
                  Executive's responsibilities or assignments, which change
                  would cause Executive's responsibilities or assignments to
                  become of less responsibility or importance from the
                  assignments and responsibilities described in Paragraph 2
                  above, and any such material change shall be deemed a
                  continuing breach of this Agreement; or

                                    B. any other breach of this Agreement by El
                  Sitio.

            Upon the occurrence of any event described in clauses A or B above,
Executive shall have the right to elect to terminate this Agreement, upon not
less than thirty (30) days prior written notice given within a reasonable period
of time not to exceed, except in case of a continuing breach, three (3) calendar
months after the event giving rise to said right to elect.

                  (b) Continuation of Benefits. Upon the occurrence of an Event
of Termination, in addition to any amounts payable pursuant to Section 3 hereof,
El Sitio shall pay monthly to Executive the compensation described an Paragraph
3 herein, including the Base Salary. Such payments shall commence on the first
day of the month following the date of termination hereof and shall continue
until the Termination Date (or the end of the renewal period, as applicable) or
twenty-four (24) months, whichever is greater (the "Severance

Period"). During the Severance Period, Executive shall continue to receive all
other benefits to which Executive was entitled under Paragraphs 3 and 4 hereof.

                  (c) Offset. If Executive becomes employed other than with El
Sitio, after an Event of Termination, but prior to the date at which the
continued Base Salary, Bonus and-other payments would have expired, any salary
received by Executive as a result of such employment will be subtracted from any
payments due Executive from El Sitio under Paragraph 5(b) hereunder.

            6. Termination for Breach by Executive.

                  (a) Conditions for Termination. Executive shall be considered
in breach of this Agreement, and the Agreement subject to termination by El
Sitio, in the following events (each, a "cause");

                        (i) Willful disobedience of lawful instructions of the
                  Board of Directors of El Sitio by Executive which continues
                  after being afforded a reasonable opportunity to cure such
                  disobedience; or

                        (ii) The commission of a felony by Executive; or

                        (iii) Gross negligence by Executive in carrying out his
                  duties on behalf of El Sitio.

                  (b) Notice. In the event El Sitio elects to terminate this
Agreement pursuant to Paragraph 6(a), El Sitio shall have a thirty (30) day
written notice of termination to Executive setting out, in detail, the reasons
for termination. Upon the expiration of such thirty (30) day notice period this
Agreement shall be wholly terminated subject to the payment to executive of any
remuneration or other amounts owing pursuant hereto.

            7. Effect of Prior Agreements. This Agreement contains the full and
complete understanding between the parties hereto with respect to the subject
matter hereof and supersedes any prior agreement between El Sitio or any
predecessor of El Sitio and Executive, except that this Agreement shall not
affect or operate to reduce any benefit or compensation inuring to Executive of
a kind elsewhere provided and not expressly provided in this Agreement.

            8. Binding Agreement This Agreement shall be binding upon, and inure
to the benefit of Executive and El Sitio and their respective permitted
successors and assigns. Notwithstanding any provision herein to the contrary, in
the event of a sale (whether by an asset acquisition, merger, consolidation,
stock acquisition or similar transaction), this

deemed to have been waived, nor shall there be any estoppel against the
enforcement of any provision of this Agreement, except by written instrument of
the party charged with such waiver or estoppel. No such written waiver shall be
deemed a continuing waiver unless specifically stated therein, and each such
waiver shall operate only as to the specific term or condition waived and shall
not constitute a waiver of such term or condition for the future or as to any
act other than that specifically waived.

            10. Governing Law. This Agreement shall be governed by the laws of
the State of New York, without regard to the conflict of laws principles
thereof.

            11. Ownership.

through which El Sitio's business is conducted. Except for illness, vacation
periods and reasonable

            5. Payments to Executive Upon Termination of Agreement.

                  (a) Termination. Upon the occurrence of an Event of

                        (i) The termination by El Sitio of this Agreement for
                  any reason (including, but not limited to, El Sitio's election
                  not to renew this Agreement pursuant to Paragraph 2(a) hereof)
                  other than "cause" (as defined in Paragraph 6 therein); or

                        (ii) Executive's termination of this Agreement, pursuant
                  to:

                              A. a material change by El Sitio of the
                  Executive's responsibilities or assignments, which change
                  would cause Executive's responsibilities or assignments to
                  become of less responsibility or importance from the
                  assignments and responsibilities described in Paragraph 2
                  above, and any such material change shall be deemed a
                  continuing breach of this Agreement; or

                              B. any other breach of this Agreement by El Sitio.

            Upon the occurrence of any event described in clauses A or B above,

                                                  Rotsztain Employment Agreement

termination hereof and shall continue until the Termination Date (or the end of
the renewal period, as applicable) or twenty-four (24) months, whichever is
greater (the "Severance Period"). During the Severance Period, Executive shall
continue to receive all other benefits to which Executive was entitled under
Paragraphs 3 and 4 hereof.

                  (c) Offset. If Executive becomes employed, other than with El
Sitio, after an Event of Termination, but prior to the date at which the
continued Base Salary, Bonus and other payments would have expired, any salary
received by Executive as a result of such employment will be subtracted from any
payments due Executive from El Sitio under Paragraph 5(b) hereunder.

            6. Termination for Breach by Executive.

                  (a) Conditions for Termination. Executive shall be considered

                        (iii) Gross negligence by Executive in carrying out his
                  duties on behalf of El Sitio.

                  (b) Notice. In the event El Sitio elects to terminate this
Agreement pursuant to Paragraph 6(a), El Sitio shall give a thirty (30) day
written notice of termination to Executive setting out, in detail, the reasons
for termination. Upon the expiration of such thirty (30) day notice period this
Agreement shall be wholly terminated subject to the payment to Executive of any
remuneration or other amounts owing pursuant hereto.

            7. Effect of Prior Agreements. This Agreement contains the full and
complete understanding between the parties hereto with respect to the subject
matter hereof and supersedes any prior agreement between El Sitio or any
predecessor of El Sitio and Executive, except that this Agreement shall not
affect or operate to reduce any benefit or compensation inuring to Executive of

any such trade secrets, information, knowledge or data to anyone other than the

<PAGE>

            2.1. Board of Directors. It is agreed that there shall be up to
seven (7) members and seven (7) alternate members of the Board, all to be
elected at the same time and serving for a term of one fiscal year, and the
Memorandum shall so provide. Each director shall be entitled to vote on all
matters presented to the Board, except as expressly provided herein.

            2.2 Election and Removal of Directors.

            (a) The Initial Stockholders shall have the right in any election of
directors to the Board to select four (4) directors. Each Stockholder agrees
that the holders of Class A Preferred shall have the right to nominate three (3)
directors to the Board, two (2) of which shall be nominated by the Ibero Group
for so long as the Ibero Group shall own ten percent (10%) or more of its
current holdings of El Sitio Stock on an as-converted basis or one (1) for so
long as the Ibero Group shall own one percent (1%) or more of El Sitio Stock on
an as-converted basis. If the Ibero Group owns less than one percent (1%) of El
Sitio Stock on an as-converted basis, the Ibero Group shall have the right to
appoint an observer to the Board, who shall be entitled to participate in the
meetings of the Board, but shall not have any vote. Chestnut shall have the
right to nominate the third of such directors for so long as Chestnut shall own
(i) two and one-half percent (2.5%) or more of the El Sitio Stock on an
as-converted basis or (ii) one percent (1%) or more of El Sitio Stock on an
as-converted basis. If Chestnut owns less than one percent (1%) of El Sitio
Stock on an as-converted basis, Chestnut shall have the right to appoint an
observer to the Board, who shall be entitled to participate in the meetings of
the Board, but shall not have any vote.

            (b) If, prior to his election to the Board, any director-nominee
shall be unwilling or unable to serve as a director of the Corporation, the
Stockholder which nominated such director shall be entitled to nominate a
replacement who shall then be the director-nominee for such Stockholder for
purposes of this Article 2. Except as set forth in Section 2.2(c) and to the
extent the Stockholders shall otherwise agree in writing, each Stockholder
agrees not to take any action or to cause the Corporation to take any action to
remove or replace any director (or any alternate therefor) nominated by another
Stockholder.

            (c) Each Stockholder agrees to vote in favor of each other's
nominees upon initial election and upon replacement. In particular, upon the
written request of any other Stockholder, each Stockholder agrees to take all
actions available to it, including, without limitation, voting or acting by
written consent, with respect to all of the El Sitio Stock that it is entitled
to vote or so act, to (i) remove from the Board any member who had been
nominated by such other Stockholder and (ii) appoint any new member designated
by such other Stockholder to fill any vacancy on the Board caused by removal,
resignation or death of a member originally nominated by such other Stockholder.
A Stockholder shall have the right to cause the removal of any director
(including those nominated by another Stockholder) for Cause, and upon notice
from a Stockholder of its desire to remove a director for Cause, setting forth a
description of the facts and circumstances which constitute "Cause," each
Stockholder agrees to take any action necessary to remove such member of the
Board for Cause, if Cause exists.

            (d) The Stockholders agree that the Memorandum shall provide for
certain notice, quorum and voting requirements for action of the Board and agree
not to take any action inconsistent with such provisions. The Memorandum shall
provide for quarterly meetings of the


                                       3

Board unless a majority in Interest of the Stockholders otherwise agree. Special
meetings of the Board may be held by conference telephone or any other means
consistent with British Virgin Islands law.

            2.3. Board Action.

            (a) Except as provided in Section 2.3(b) below or in the Memorandum
or in applicable law, all actions of the Board shall require the affirmative
vote of four (4) directors. Unless prohibited by applicable law, the directors
shall be permitted to vote on any matter brought before the Board. The
Stockholders and the Corporation agree to take any action necessary or desirable
to effect the foregoing.

            (b) The Stockholders agree that the matters set forth below will
require the affirmative vote of the majority of the directors nominated by the
holders of the Class A Preferred Stock:

                  (i) any guarantees, loans or contractual obligations to make

Subsidiary having a fair value of more than $100,000 which constitute less than
all or substantially all of the assets of the Corporation;

                  (viii) any transactions between the Corporation or any of its
Subsidiaries, on the one hand, and any Stockholder or any of its Affiliates, on

            2.5. Right to Inspect Records. Each Stockholder shall have the right

unaudited financial statement need not contain all of the required footnotes and

            2.7. Ethical Business Practices. Each Stockholder agrees, severally
and not jointly, not to offer or give on behalf of the Corporation or any of its
Subsidiaries, and the Corporation agrees not to offer or give, either directly
or through a Third Party, anything of value to: (a) any government official, any
political party or official thereof, or any candidate for political office; (b)
any customer or member of the government; or (c) any other Person, in any such
case while knowing or having reason to know that all or a portion of such money
or thing of value may be offered, given or promised, directly or indirectly, to
any customer or member of the government or candidate for political office for
the purpose of the following: (i) influencing any action or decision of such
Person, in his or its official capacity, including a decision to fail to perform
his or its official function; (ii) inducing such Person to use his or its
influence with any government or instrumentality thereof to effect or influence

<PAGE>

business for, or with, or directing business to, any Person; or (iii) where such
payment would constitute a bribe, kickback or illegal or improper payment.

            2.8. Liability Insurance. The Corporation will maintain in full
force and effect directors' and officers' liability insurance with a reputable,
financially stable insurance company in such amounts and on such usual and
customary terms (including, without limitation, as to coverage for claims
against directors following the termination of their Board service) as the Board
shall authorize from time to time.

            2.9. Compensation Committee and Audit Committee. The board of

as long as Chestnut retains its Board seat. One (1) representative shall be
appointed by the Initial Stockholders to each of the committees.

ARTICLE 3. Transfers of Shares; Preemptive Rights

            3.1. Restriction on Transfer. The El Sitio Stock held by any
Stockholder and comprising its Interest ("Covered Stock") shall not be
transferable, directly or indirectly, except upon the conditions specified in
this Article 3, which conditions are intended in part to ensure compliance with
the provisions of the Securities Act in respect of any disposition of any
Covered Stock or any interest therein which would constitute a sale thereof
within the meaning of the Securities Act (a "Transfer"). As used in this Article
3, the term "Transferor" refers to the transferor (whether by voluntary or
involuntary means) of any Covered Stock, the term "Other Stockholder" means the
Stockholder which is not the Transferor, and the term "Subject Shares" means the
shares of Covered Stock that have been or are to be Transferred.

            3.2. Involuntary Transfers. In the event that an Involuntary
Transfer (as hereinafter defined) by any Stockholder of any Covered Stock may
occur, the following procedures shall apply:

            (a) The Stockholder to be deprived or divested of Covered Stock by
the Involuntary Transfer shall promptly give written notice of such Involuntary
Transfer in reasonable detail to the Corporation and to the Other Stockholders
and the person or persons who take or propose to take any interest in the
Subject Shares as a result of such Involuntary Transfer (the "Transferee") shall
hold such interest subject to the rights of the Other Stockholder as set forth
below.

            (b) Upon receipt of the notice referred to in Section 3.2(a) above
or upon discovery of such Involuntary Transfer, the Corporation shall cause the
appraisal referred to in Section 3.2(c) to be made and each of the Other
Stockholders shall have the irrevocable option, but not the obligation, for a
period of sixty (60) days following receipt by all Other Stockholders of the
results of such appraisal, to purchase the Subject Shares, subject to the terms
set forth


                                       8
<PAGE>

herein. Each Other Stockholder may exercise the option for the number of Subject
Shares which bears the same relation to the total number of Subject Shares as
(x) such Other Stockholder's Interest bears to (y) the aggregate Interest then
held by all of the Other Stockholders exercising such option (and purchasing
Subject Shares under Section 3.2(c) below), or for such other number of Subject
Shares as all of the Other Stockholders exercising such option may agree in
writing. In the event that the Other Stockholders elect to purchase, in the
aggregate, less than all of the Subject Shares, then the Other Stockholders
shall have no right to purchase any of the Subject Shares.

            (c) The closing for any such sale of Subject Shares to one or more
Other Stockholders shall be at the offices of the Corporation on a mutually
satisfactory business day within fifteen (15) days after the expiration of such
sixty (60) day period. The purchase price per share of any Subject Shares
purchased pursuant to this Section 3.2 shall be the amount which is equal to the
fair value, as of the Valuation Date (as hereinafter defined), of a Subject
Share, as such fair value is determined by an independent appraiser selected by
the Corporation and reasonably acceptable to the Stockholders holding, in the
aggregate, the majority of the aggregate Interests, and all costs of any such
appraisal shall be paid by the Corporation. The "Valuation Date" shall be the
last day of the calendar quarter immediately preceding the Involuntary Transfer.

            (d) For purposes of this Agreement, the term "Involuntary Transfer"
shall mean any involuntary sale, transfer, encumbrance or other disposition by
or in which any Stockholder shall be deprived or divested of any right, title or
interest in or to any Covered Stock, including, without limitation, any levy of
execution, transfer in connection with bankruptcy, judicial reorganization,
insolvency or similar proceedings or any transfer to a public officer or agency
pursuant to any abandoned property or escheat law; provided that any Transfer
complying with Section 3.3, Section 3.4, Section 3.5 or Section 3.6 hereof shall
not be deemed to be an "Involuntary Transfer."

            3.3. Rights of First Offer. Except as otherwise expressly provided
in Sections 3.4 and 3.5 hereof, each Stockholder hereby agrees that it shall not
effect a Transfer of any Covered Stock, except in accordance with the following
procedures:

            (a) In the event that a Stockholder wishes to make a Transfer of any
Covered Stock, the Transferor shall first deliver to the Other Stockholders a
written notice (the "Offer Notice"), which Offer Notice shall (i) specify the
terms, including the number of shares of Covered Stock to be sold, and the price
per share at which the Transferor proposes to Transfer such Covered Stock, and
(ii) be irrevocable for a period of fifteen (15) days after delivery thereof,
offering (the "Offer") to the Other Stockholders all of the Subject Shares
proposed to be sold by the Transferor at the purchase price and on the terms
specified therein. Each of the Other Stockholders shall have the right and
option, at its sole discretion, for a period of fifteen (15) days after delivery
of the Offer Notice (the "Acceptance Period"), to accept all, but not less than
all, of the Subject Shares (pro rata among such Other Stockholders so electing
on the basis of the number of shares of El Sitio Stock owned by such Other
Stockholders) offered at a price equal to the purchase price and upon the other
terms stated in the Offer Notice. Such acceptance may be made by delivery of a
written notice to the Transferor within said fifteen (15) day period, which
notice shall specify whether such Stockholder wishes to purchase more than its
pro rata share, if


                                       9
<PAGE>

Other Stockholders decline to purchase, and if so, the maximum purchase such
Stockholder elects to make. In the event that any Stockholder elects not to
exercise its pro rata right to purchase, the Other Stockholder(s) shall have the
right to purchase the Subject Shares otherwise allocable to the
non-participating Stockholder pro rata to their participation in the Offer,
subject to the limits set forth in the applicable Acceptance Notice. In the
event that the Other Stockholders elect not to purchase all of the Subject
Shares, then the Other Stockholders shall have no right to purchase all or any
portion of such Subject Shares and the Transferor shall be free to Transfer the
Subject Shares in accordance with Section 3.3(c). A Stockholder electing to
purchase Subject Shares pursuant to this Section 3.3 is referred to herein as a
"Purchasing Stockholder").

            (b) Notwithstanding anything to the contrary contained in Section
3.3 hereof, in the event the Transferor is one of the (i) Initial Stockholders,
the other Initial Stockholders will have a priority right of first offer with
respect to any Subject Shares offered by an Initial Stockholder, in accordance
with the terms and conditions of the Syndication Agreement among the Initial
Stockholders and dated as of June 10, 1999, before any such right may be
exercised by the Stockholders of any other class or (ii) holders of Class A
Preferred, the other holders of Class A Preferred will have a priority right of
first offer with respect to any Class A Preferred offered by a holder of Class A
Preferred, before any such right may be exercised by the other Stockholders.

            (c) Transfers, if any, of Subject Shares to the Purchasing
Stockholder under the terms of this Section 3.3 shall be made at the offices of
the Corporation or any other address acceptable to the Corporation on a mutually
satisfactory business day within fifteen (15) days after the expiration of the
Acceptance Period. The Transferor shall deliver the Subject Shares by delivering
shares, duly endorsed for transfer, against payment of the purchase price
thereof, in accordance with the terms of the Offer.

            (d) If effective acceptance shall not be received pursuant to
Section 3.3(a) above, with respect to all Covered Stock offered for sale
pursuant to the Offer Notice, then the Transferor may Transfer all or any part
of the El Sitio Stock so offered for sale at a price not less than the price,
and on terms not more advantageous to the purchaser than the terms stated in the
Offer Notice at any time within one hundred eighty (180) days after the
expiration of the Acceptance Period.

            (e) In the event that any Stockholder exercises a purchase right
under Section 3.3(a) and then fails to consummate such purchase in accordance
with the terms of the Offer Notice (each such Stockholder, a "Defaulting
Stockholder"), then, in addition to any remedies at law or in equity that the
Transferor may have in respect of such failure, the Defaulting Stockholder shall
thereafter cease to have any right to receive offers or purchase shares pursuant
to Section 3.3(a).

            3.4. Exempt Transfers. Anything contained herein to the contrary
notwithstanding, the provisions of Sections 3.3, 3.5 and 3.6 shall not be
applicable to a Transfer (i) to an Affiliate of a Stockholder or for the benefit
of an Affiliate or family member of a Stockholder, if made solely for personal
tax or estate planning purposes, or (ii) in an offering pursuant to the exercise
of registration rights under the Registration Rights Agreement, provided


                                       10
<PAGE>

such Affiliate executes all documents (including the representation that such
Transfer may be effected without registration under the applicable provisions of
the Securities Act and state securities or blue sky laws) deemed reasonably
necessary by the Other Stockholder to cause the Affiliate to become a party to,
and be bound by, the terms of this Agreement.

            3.5. Tag-Along Rights.

            (a) Right to Participate in Sale. Notwithstanding any other
provision hereof, if any Stockholder party hereto (such Stockholders, together
with their Affiliates, the "Selling Stockholder(s)") proposes to enter into an
agreement with a third party to sell or otherwise dispose of for value (such
sale or other disposition for value being referred to as a "Tag-Along Sale") El
Sitio Stock held by it to a third party who is not an Affiliate (any such party,
a "Third Party") pursuant to a bona fide transaction (or series of related
transactions) in which securities representing an aggregate Interest of fifty
percent (50%) or more will be sold to a Third Party, then the Selling
Stockholder(s) shall afford the other Stockholder(s) (the "Tag-Along
Stockholder") the opportunity to require that the sale by the Selling
Stockholder(s) be conditioned upon such Third Party purchasing that number of
shares of El Sitio Stock owned by such Tag-Along Stockholder which delivers a
Tag-Along Notice in accordance with Section 3.5(c) equal to the product (rounded
up to the nearest whole number) of (i) the quotient determined by dividing (A)
the number of shares of El Sitio Stock owned by such Tag-Along Stockholder, by
(B) the number of shares of El Sitio Stock owned by the Selling Stockholders and
all Tag-Along Stockholders which are selling shares of El Sitio Stock in the
contemplated Tag-Along Sale, and (ii) the number of shares of El Sitio Stock
proposed to be sold by all Stockholders in the contemplated Tag-Along Sale. In
negotiating a Tag-Along Sale, the Selling Stockholder(s) shall provide (i) that
the only representations, warranties or covenants which any Tag-Along
Stockholder shall be required to make in connection with any Transfer are
representations and warranties with respect to its own ownership of the shares
to be sold by it and its ability to convey title thereto free and clear of
liens, encumbrances or adverse claims, its due organization, its due
authorization, execution and delivery of the definitive purchase agreement (if
applicable), enforceability of such purchase agreement against it and no
conflict of it with such purchase agreement, and (ii) that the liability of the
Tag-Along Stockholder with respect to any representation and warranty made in
connection with any Transfer is the several liability of such Tag-Along
Stockholder (and not joint with any other person) and that such liability is
limited to the amount of proceeds actually received by such Tag-Along
Stockholder; provided, however, that the foregoing shall not limit the
obligations of such Tag-Along Stockholder, and such Tag-Along Stockholder hereby
expressly agrees to be bound by and be subject to, any escrow or other holdback
arrangement (on a pro rata basis based on the number of shares sold by such
Tag-Along Stockholder in proportion to all shares of the Corporation sold in
such Tag-Along Sale) provided for in the agreement relating to the Tag-Along
Sale.

            (b) Sale Notice. The Selling Stockholder(s) shall provide each
Tag-Along Stockholder and the Corporation with written notice (the "Tag-Along
Sale Notice") not less than thirty (30) days prior to the proposed date of the
Tag-Along Sale (the "Tag-Along Sale Date"). Each Tag-Along Sale Notice shall be
accompanied by a copy of any agreement relating to the Tag-Along Sale (if
available) and shall set forth: (i) the name and address of the Third Party in
the Tag-Along Sale; (ii) the number of shares proposed to be Transferred by the
Selling Stockholder(s); (iii) the proposed amount and form of consideration to
be paid for such shares


                                       11
<PAGE>

expressed on a per share basis and the terms and conditions of payment offered
by the Third Party; (iv) the aggregate number of shares of the Corporation held
of record by the Selling Stockholder(s) as of the close of business on the day
immediately preceding the date of the Tag-Along Notice (the "Tag-Along Notice
Date"); (v) confirmation that the Third Party has been informed of the
"Tag-Along Rights" provided for herein and has agreed to purchase shares from
any Tag-Along Stockholder in accordance with the terms hereof; and (vi) the
Tag-Along Sale Date.

            (c) Tag-Along Notice. Any Tag-Along Stockholder wishing to
participate in the Tag-Along Sale shall provide written notice (the "Tag-Along
Notice") to the Selling Stockholder(s) no less than fifteen (15) days prior to
the Tag-Along Sale Date. The Tag-Along Notice shall set forth the number of
shares of El Sitio Stock that such Tag-Along Stockholder elects to include in
the Tag-Along Sale. The Tag-Along Notice given by any Tag-Along Stockholder
shall constitute such Tag-Along Stockholder's binding agreement to sell the
shares specified in the Tag-Along Notice on the terms and conditions applicable
to the Tag-Along Sale; provided, however, that in the event that there is any
material change in the material terms and conditions of such Tag-Along Sale
applicable to the Tag-Along Stockholder (including, but not limited to, any
decrease in the purchase price that occurs other than pursuant to an adjustment
mechanism set forth in the agreement relating to the Tag-Along Sale) after such
Tag-Along Stockholder gives its Tag-Along Notice, then, notwithstanding anything
herein to the contrary, the Tag-Along Stockholder shall have the right to
withdraw from participation in the Tag-Along Sale with respect to all of its
shares affected thereby. If the Third Party does not consummate the purchase of
all the shares requested to be included in the Tag-Along Sale by any Tag-Along
Stockholder on terms and conditions which are no more favorable in any material
respect to the Selling Stockholder (except as otherwise provided herein), then
the Selling Stockholder(s) shall not consummate the Tag-Along Sale of any of its
shares to the Third Party. If a Tag-Along Notice from any Tag-Along Stockholder
is not received by the Selling Stockholder(s) prior to the fifteen (15) day
period specified above, the Selling Stockholder(s) shall have the right to
consummate the Tag-Along Sale without the participation of such Tag-Along
Stockholder, but only on terms and conditions which are no more favorable in any
material respect to the Selling Stockholder (and in any event, at no greater a
purchase price, except as the purchase price may be adjusted pursuant to the
agreement regarding the relevant sale or other disposition) than as stated in
the Tag-Along Sale Notice and only if such Tag-Along Sale occurs on a date
within one hundred eighty (180) days of the Tag-Along Sale Date. If such
Tag-Along Sale does not occur within such one hundred eighty (180) day period,
the shares of El Sitio Stock that were to be subject to such Tag-Along Sale
thereafter shall continue to be subject to all of the restrictions contained in
this Agreement.

            (d) Delivery of Shares. On the Tag-Along Sale Date, each Tag-Along
Stockholder shall deliver the shares to be sold in connection with the Tag-Along
Sale to the Third Party by delivering shares, duly endorsed for transfer,
against delivery of immediately available funds in the amount of the purchase
price for such shares.

            (e) No Waiver. Any election in any instance by a Stockholder not to
exercise its rights to participate in a Tag-Along Sale under this Section 3.5
shall not constitute a waiver of such rights with respect to any other proposed
Transfer of shares of the Corporation which would trigger such rights.


                                       12

            3.6. Drag-Along Rights.

            (a) Grant of Drag-Along Rights. If any Stockholder party hereto
(such Stockholders, together with their Affiliates, the "Selling
Stockholder(s)") proposes to enter into an agreement with a third party to sell
or otherwise dispose of for value (such sale or other disposition for value
being referred to as a "Drag-Along Sale") El Sitio Stock held by it to a third
party who is not an Affiliate (any such party, a "Third Party") pursuant to a
bona fide transaction (or series of related transactions) in which securities
representing an aggregate Interest of fifty percent (50%) or more will be sold
to a Third Party, then the remaining Stockholder(s) (the "Drag-Along
Stockholder") shall, upon the written request of the Selling Shareholder(s),
sell to such Third Party (i) El Sitio Stock owned by such Drag-Along Stockholder
equal to (A) the number of shares of El Sitio Stock owned by such Drag-Along
Stockholder multiplied by (B) a fraction ("Drag-Along Fraction"), the numerator
of which is the number of shares of El Sitio Stock, the Selling Shareholder(s)
intend to sell pursuant to this Section 3.6 and the denominator of which is the
aggregate number of shares of El Sitio Stock owned by the Selling
Shareholder(s), and (ii) warrants owned by such Drag-Along Stockholder
representing the right to acquire a number of shares equal to (A) the number of
shares underlying such Drag-Along Stockholders warrants multiplied by (B) the
Drag-Along Fraction, contemporaneously with the sale of such El Sitio Stock by
the Selling Stockholder(s), for, with respect to the El Sitio Stock, the same
consideration and on the same terms as those provided by such Third Party to the
Selling Stockholder(s) and, with respect to the warrants, for the same
consideration and on the same terms as those provided by such Third Party to the
Selling Stockholder(s) less the aggregate exercise price for the warrants so
transferred.

            (b) Exercise of Drag-Along Right. The Drag-Along Right shall be
exercisable by written notice given by the Selling Stockholder(s) to each
Drag-Along Stockholder, containing the price and other material terms of the
proposed sale and the date of the closing of the proposed sale (the "Drag-Along
Sale Date"), which date shall not be less than twenty (20) nor more than sixty
(60) calendar days after the date of such notice.

            (c) Delivery of Shares. On the Drag-Along Sale Date, each Drag-Along
Stockholder shall deliver the shares to be sold in connection with the
Drag-Along Sale to the Third Party by delivering shares, duly endorsed for
transfer, against delivery of immediately available funds in the amount of the
purchase price for such shares.

            3.7. Transfers in Violation of Agreement. If any voluntary Transfer
of El Sitio Stock is made or attempted contrary to the provisions of this
Agreement (such Transfer, an "Unauthorized Transfer"), the Other Stockholders
shall have the right to purchase all or part of such El Sitio Stock from the
owner thereof or the owner's transferee at any time before or after the Transfer
at a purchase price per share equal to (i) if any shares of El Sitio Stock are
listed for trading on NASDAQ or the Bolsa de Comercios de Buenos Aires, the
lesser of (x) eighty percent (80%) of the thirty (30) day average closing price
over the thirty day period immediately preceding the date of the initial
Transfer contrary to this Agreement, or (y) eighty percent (80%) of the thirty
(30) day average closing price for the thirty days immediately preceding the
date of exercise of the right granted to the Other Stockholders herein, or (ii)
if no shares of El Sitio Stock are listed for trading on NASDAQ or the Bolsa de
Comercios de Buenos Aires, the lesser of (x) eighty percent (80%) of the Fair
Value at the time of the initial transfer that was contrary to this


                                       13
<PAGE>

Agreement, or (y) eighty percent (80%) of the Fair Value at the time of the
Other Stockholders' purchase of such El Sitio Stock. The term "Fair Value" shall
mean the amount at which the El Sitio Stock would change hands between an
independent, willing buyer and an independent, willing seller, each having
reasonable knowledge of all relevant facts and neither being under any
compulsion to act (considering, where applicable, the relative rights of all
outstanding classes or series of capital stock but not discounting the value of
such securities for illiquidity or because they represent a minority ownership
position in the Corporation), which amount shall be determined by the Board of
Directors of the Corporation in its reasonable discretion and in good faith.

            3.8. Preemptive Rights.

            (a) Except for the issuance of the Corporation's capital stock or
other securities (i) pursuant to a Qualifying IPO, (ii) comprising additional
stock or option issuances to Employees of the Corporation pursuant to stock
option plans existing on the date hereof including the number of shares issuable
thereunder as of the date hereof (or amendments to such plans or new plans if
agreed to by the Stockholders) or (iii) in connection with acquisitions of
businesses by the Corporation approved by the Stockholders, if the Corporation
at any time after the date hereof authorizes the issuance or sale of any capital
stock of the Corporation or any securities of the Corporation containing options
or rights to acquire any shares of capital stock (other than as a dividend on
the outstanding capital stock), the Corporation shall first offer to sell to the
Stockholders on a pro rata basis, all of such capital stock or other securities
(the "Offered Shares").

            (b) In order to exercise its purchase rights under this Section 3.8,
each Stockholder must within twenty (20) business days after receipt of written
notice from the Corporation describing in reasonable detail the capital stock or
securities being offered, the purchase price thereof and the payment terms,
deliver a written notice to the Corporation describing its election hereunder.
Such election shall indicate the number of Offered Shares that the Stockholder
in its sole discretion elects to purchase, which may be all or any portion of
the Offered Shares. The Corporation shall give the Stockholders no less than
fifteen (15) business days notice of the closing of the sale and purchase of
such shares.

            (c) Upon the expiration of the 20-day period described above, the
Corporation shall be entitled to sell such capital stock or securities which the
Stockholder has not elected to purchase during the ninety (90) days following
such expiration on terms and conditions, including price, no more favorable to
the purchasers thereof than those offered to the Stockholders. Any capital stock
or securities offered or sold by the Corporation to any person after such 90-day
period must be re-offered to the Stockholders pursuant to the terms of this
Section 3.8.

ARTICLE 4. Other Agreements

            IAMP (El Sitio) Investments Ltd.., Washburn and the Corporation
agree to use reasonable efforts to exploit jointly strategic business
opportunities in the future, including, but not limited to: (i) the Ibero Group
advertising on the Internet site of the Corporation and the Corporation
advertising on media networks of the Ibero Group and its Affiliates (including


                                       14
<PAGE>

agreements whereby the Corporation will utilize media networks of the Ibero
Group and its Affiliates as the preferred choice for its advertising
expenditures); (ii) the Corporation and the Ibero Group developing Internet
sites for Ibero Group's media networks as a preferred provider; (iii) the
Corporation and the Ibero Group sharing production and advertising sales assets;
and (iv) the Corporation and the Ibero Group sharing offices and other
administrative overhead; provided, however, that such opportunities are mutually
beneficial for both Ibero Group and the Corporation. The Ibero Group and the
Corporation agree that these strategic business opportunities are intended to be
a part of a long-term strategic initiative.

ARTICLE 5. Miscellaneous

            5.1. Notices. Any and all notices, designations, consents, offers,
acceptances, or any other communication required or permitted to be given by any
provision of this Agreement shall be deemed to be sufficient if contained in a
written instrument delivered in person or duly sent by telecopier with
acknowledgment of receipt sent by telecopier or delivered in person, as the case
may be, to such party at the address or telecopier number, as the case may be,
set forth on the signature pages hereto. All such notices, requests, consents
and other communications shall be deemed to have been received: (a) in the case
of personal delivery, on the date of receipt; or (b) in the case of telecopying,
on the date of acknowledgment thereof.

            5.2. Amendment and Waiver. No change or modification of, or waiver
of compliance with, this Agreement shall be valid unless the same shall be in
writing and signed by each of the Stockholders party hereto which holds an
Interest of one percent (1%) or more.

            5.3. Termination. This Agreement may be terminated at any time by an
instrument in writing signed by all of the Stockholders party hereto. This
Agreement shall terminate automatically as to any Stockholder which transfers
all of its El Sitio Stock, or upon the occurrence of a Qualifying IPO (as
defined in the Memorandum). Unless sooner terminated, this Agreement shall
terminate ten (10) years from the date hereof, unless, at any time within one
(1) year prior to such date, all of the parties extend its duration for as many
additional periods, each not to exceed ten (10) years, as they may desire.

            5.4. No Waiver. No failure or delay on the part of the Stockholders
or any of them in exercising any right, between the Corporation and the
Stockholders or any of them shall operate as a waiver thereof nor shall any
single or partial exercise of any right, power or privilege hereunder preclude
the simultaneous or later exercise of any other right, power or privilege. The
rights and remedies herein expressly provided are cumulative and not exclusive
of any rights or remedies which the Stockholders or any of them would otherwise
have. No notice to or demand on the Corporation in any case shall entitle the
Corporation to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Stockholders or any of
them to take any other or further action in any circumstances without notice or
demand.

            5.5. Specific Performance. Each party to this Agreement acknowledges
that the other parties will suffer irreparable injury in the event of any breach
of any provision of this Agreement and that therefore the remedy at law for any
breach or threatened breach of any such provision of this Agreement will be
inadequate. Accordingly, upon a breach or threatened breach of any such
provision of this Agreement by any party hereto, the other parties shall, in


                                       15
<PAGE>

addition and without prejudice to any of the rights and remedies they may have,
be entitled as a matter of right, without proof of actual damages, to seek
specific performance of such provisions of this Agreement and to such other
injunctive or equitable relief to enforce, or prevent any violations (whether
anticipatory, continuing or future) of, such provisions of this Agreement.

            5.6. Counterparts and Headings. This Agreement may be executed in
two or more counterparts, each of which shall be deemed to be an original, but
all of which together shall constitute one and the same instrument. All headings
and any cover page or table of contents are inserted for convenience or
reference only and shall not affect its meaning or interpretation.

            5.7. Nouns and Pronouns. Whenever the context may require, any
pronouns used herein shall include the corresponding masculine, feminine or
neuter forms, and the singular form of nouns and pronouns shall include the
plural and vice-versa. Dollars or $ means the currency of the United States or
its foreign currency equivalent at the time the determination is made.

            5.8. Expenses. Each of the parties to this Agreement shall bear its
own expenses, including, without limitation, the fees and disbursements of its
respective counsel, in connection with the negotiation and execution of this
Agreement and the consummation of the transactions contemplated hereby.

            5.9. Governing Law. This Agreement will be governed by, and
construed and enforced in accordance with, the laws of the British Virgin
Islands, without regard to its conflict of law rules.

            5.10. Dispute Resolution.

            (a) Any and all disputes between or among the parties arising in
connection with or relating in any way to the validity, construction, meaning,
enforceability or performance of this Agreement shall be settled by binding
arbitration in accordance with the rules of arbitration then in effect (the "ICC
Rules") of the International Chamber of Commerce (the "ICC"). Any party or
parties electing to refer a matter to arbitration pursuant hereto (the
"Petitioner") shall promptly deliver written notice (the "Arbitration Notice")
to the other parties that it wishes to commence an arbitration proceeding under
this Section 5.10. The Arbitration Notice shall set forth the matter being
referred to arbitration and the name of the individual selected by the
Petitioner as one of the arbitrators.

            (b) There shall be three (3) arbitrators, and each party to the
arbitration shall select one (1) arbitrator. Within twenty (20) days of receipt
of the Arbitration Notice, the other party to such arbitration (the
"Respondent") shall appoint an arbitrator (who shall have appropriate
qualifications in relation to the matter in dispute) and notify the Petitioner
of such appointment and submit its counter statement, if any, of the matter
being referred to arbitration. If the Respondent fails to appoint an arbitrator
within such twenty (20) day period, the Petitioner shall request the ICC
President to appoint a second arbitrator who shall have appropriate
qualifications in relation to the matter in dispute. Within twenty (20) days
after appointment of the second arbitrator, the two arbitrators shall appoint
the third arbitrator. If the two arbitrators


                                       16
<PAGE>

fail to appoint the third arbitrator within such twenty (20) day period, either
party to the arbitration may request that the ICC President appoint the third
arbitrator, who shall have appropriate qualifications in relation to the matter
in dispute. All three (3) arbitrators shall be bilingual (Spanish/English). In
the event that there are more than two (2) parties to such arbitration, all
three (3) arbitrators shall be appointed by the ICC President.

            (c) The arbitration proceedings shall be conducted in the English
and Spanish languages in London, England, in accordance with the ICC Rules, and
all documents in connection with any such proceedings shall be submitted in the
English or Spanish languages or with a complete and accurate English or Spanish
(as applicable) language translation. In any arbitration, the decision of the
arbitrators shall be final and binding on the parties to the arbitration and
judgment on the decision may be entered in and enforced in any court of
competent jurisdiction in accordance with the New York Convention on the
Recognition and Enforcement of Arbitral Awards. The substantially prevailing
party in such arbitration, in addition to all other relief provided, shall be
entitled to an award of all its reasonable costs and expenses including attorney
fees and expenses and deposits and payments to the ICC.

            (d) Each party hereto hereby agrees that each of the parties hereto
shall have the right to seek appropriate emergency or equitable relief to
preserve the arbitral matter or to otherwise protect its rights pending
resolution of the arbitral matter, whether in New York, New York, Argentina or
in any other jurisdiction.

            5.11. Successors and Assigns. This Agreement shall be binding upon
and shall inure to the benefit of each of the Stockholders and their respective
executors, administrators and personal representatives and heirs and their
successors and assigns. The rights and obligations of any Stockholder hereunder
shall inure to the benefit of and be binding upon any transferee of such
Stockholder, if (i) such transferee agrees in writing to be bound by the
provisions of this Agreement and (ii) the Interest of such transferee would,
immediately upon becoming a party to this Agreement, equal or exceed five
percent (5%).

            5.12. Severability. In the event that any provision of this
Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, invalid or unenforceable, the remaining provisions hereof shall
nevertheless continue in full force and effect as though the illegal, invalid or
unenforceable provisions were not a part hereof, and the parties shall exert
their best efforts to amend this Agreement to include a provision which is
legal, valid and enforceable and which carries out the original intent of the
parties.

            5.13. Complete Agreement. This Agreement contains the entire
agreement among the parties with respect to the subject matter hereof and
supersedes all prior and contemporaneous arrangements or understandings, whether
written or oral, between or among any of the parties hereto, with respect to the
subject matter hereof, other than the Registration Rights Agreement and the
Syndication Agreement among the Initial Stockholders, dated as of June 10, 1999.

            5.14. Further Assurances. Each of the parties to this Agreement
agrees to execute such other documents and take such other action as may be
reasonably necessary to implement and carry out the intent of this agreement.

            5.15. Conflict with Memorandum. In the event that any of the terms
or provisions contained herein conflict with any of the provisions contained in
the Memorandum, the provisions of this Agreement shall govern to the extent that
they are consistent with applicable British Virgin Islands law, as in effect
from time to time.

            5.16. Confidentiality. Each Stockholder covenants and agrees to
treat any non-public information provided to it by the Corporation concerning
the business and finances of the Corporation ("Corporate Information") as
confidential and agrees further that it will not use, exploit, reproduce,
disclose or provide Corporate Information to any third party (other than any
agents of the Stockholder who are bound by substantially similar obligations of
confidentiality) on its own behalf or otherwise, except with the consent of the
Corporation or as required by law, legal process or any federal or state
regulatory body having jurisdiction over such Stockholder. The provisions of
this Section 5.16 shall not apply to any information which:

            (a) was within the public domain prior to the time of disclosure of
Corporate Information to the Stockholder or which comes into the public domain
other than as a result of a breach by the Stockholder of this Section 5.16;

            (b) was in the possession of the Stockholder (or any of its
officers, directors, employees, agents, principals, or Affiliates) before the
Stockholder received the Corporate Information;

            (c) was rightfully acquired by the Stockholder from a third party
without, to the knowledge of the Stockholder, any restriction or any obligation
of confidentiality; or

            (d) was independently developed by the Stockholder without any use
or reference to the Corporate Information.

            The provisions of this Section 5.16 shall survive the termination of
this Agreement, either in whole or as to any Stockholder, for a period of two
(2) years.

            5.17. Failure to Execute. Failure of any party to execute this
Agreement renders this Agreement void as to the non-executing party, but such
Agreement shall be valid and binding as to all other parties that execute such
Agreement.

ARTICLE 2. Registration Rights

            2.1 Demand Registration.

            (a) Upon notice to the Corporation from Stockholder(s) holding in
the aggregate $15.0 million or more of the Restricted Shares (or Preferred
Shares which are convertible into Restricted Shares), such Stockholders (the
"Requesting Stockholders") shall have the right to request in writing a
registration of such shares of Stock that are (or which would be upon
conversion) Restricted Shares. Such request (a "Demand Request") by the
Requesting Stockholders shall (i) specify the number of Restricted Shares which
each Requesting Stockholder intends to sell or dispose of, and (ii) state the
intended method or methods by which the Requesting Stockholder intends to sell
or dispose of such Restricted Shares. Upon receipt of a Demand Request pursuant
to this Section 2.1, the Corporation shall (as requested) (i) cause to be filed,
within the later of (x) ninety (90) days of the date of delivery to the
Corporation of the Demand Request, or (y) one hundred eighty (180) days after
the effectiveness of the most recently filed registration statement by the
Corporation, a registration statement covering such Restricted Shares which the
Corporation has been so requested to register, providing for the registration
under the Securities Act of such Restricted Shares to the extent necessary to
permit the disposition of such Restricted Shares so to be registered in
accordance with the intended method of distribution specified in such Demand
Request, provided, that the Corporation may delay making such filing or taking
such action by not more than one hundred twenty (120) days if the Corporation,
prior to the time it would otherwise have been required to file such
registration statement or take such action, determines in good faith that the
filing of such registration statement or the taking of such action would require
the disclosure of material, non-public information that, in the reasonable
judgment of the Corporation, would be detrimental to the Corporation if so
disclosed (and a delay would be likely to reduce the detrimental effect of such
disclosure or obviate the need for such disclosure to be made, or would
otherwise adversely affect a financing, acquisition, disposition, merger or
other material transaction), (ii) shall use its


                                       2
<PAGE>

best efforts to have such registration statement declared effective by the
Commission as soon as practicable thereafter, and (iii) refrain from filing any
other registration statements with respect to any other securities of the
Corporation until such date which is one hundred eighty (180) days following
effectiveness of the registration statement filed in response to the Demand
Request. Subject to any existing written agreement between the Corporation and
Bear, Stearns & Co. Inc., the underwriter shall be selected by the Requesting
Stockholders and shall be reasonably acceptable to the Corporation for any
registration pursuant to this Section 2.1.

            (b) In the event that the Corporation is required to file a
registration statement covering any Restricted Shares of any Requesting
Stockholder(s) pursuant to Section 2.1(a) above, the Corporation shall be
permitted to include newly-issued securities ("Piggyback Securities") in such
registration. Notwithstanding the foregoing, if the managing underwriter of such
proposed registration determines and advises in writing that the inclusion of
all Piggyback Securities proposed to be included in the underwritten public
offering would interfere with the successful marketing of the Requesting
Stockholders' Restricted Shares, then the Corporation shall not be permitted to
include any Piggyback Securities in excess of the amount, if any, of Piggyback
Securities which the managing underwriter of such underwritten offering shall
reasonably and in good faith agree in writing to include in such offering in
excess of any amount to be registered for the Requesting Stockholder(s). The
Piggyback Securities that are excluded from the underwritten public offering
pursuant to the preceding sentence shall be withheld from the market by the
Corporation for a period, not to exceed 180 days from the closing of such
underwritten public offering, that the managing underwriter determines is
necessary in order to effect such underwritten public offering.

            (c) The Corporation shall not be required to comply with more
than four (4) Demand Requests, at least one (1) of which shall be reserved
for IAMP (El Sitio) Investments Ltd. (and its affiliates) and at least one
(1) of which shall be reserved for the Initial Stockholders.

            2.2 Piggyback Registration.

            (a) Each time that the Corporation proposes for any reason to
register any of its Stock under the Securities Act (a "Proposed Registration"),
other than pursuant to a registration statement on Form F-4 or Form F-8 or
similar or successor forms, the Corporation shall promptly give written notice
of such Proposed Registration to the holders of the Restricted Shares (which
notice shall be given not less than thirty (30) days prior to the expected
effective date of the Corporation's registration statement) and shall offer such
holders the right to request inclusion of any of such holder's Restricted Shares
in the Proposed Registration. No registration pursuant to this Section 2.2 shall
relieve the Corporation of its obligation to register Restricted Shares pursuant
to Section 2.1.

            (b) Each Stockholder shall have twenty (20) days from the receipt of
such notice to deliver to the Corporation a written request specifying the
number of Restricted Shares such Stockholder intends to sell and such
Stockholder's intended method of disposition. Any Stockholder shall have the
right to withdraw such Stockholder's request for inclusion of such Stockholder's
Restricted Shares in any registration statement pursuant to this Section 2.2 by
giving written notice to the Corporation of such withdrawal. Subject to Section
2.3 below, the Corporation shall include in such registration statement all such
Restricted Shares so requested to


                                       3
<PAGE>

be included therein; provided, however, that the Corporation may at any time
withdraw or cease proceeding with any such Proposed Registration if it shall at
the same time withdraw or cease proceeding with the registration of all other
equity securities originally proposed to be registered.

            (c) In the event that the Proposed Registration by the Corporation
is, in whole or in part, an underwritten public offering of securities of the
Corporation, any request under Section 2.2(b) hereof must specify that the
Restricted Shares be included in the underwriting on the same terms and
conditions as the shares of Stock, if any, otherwise being sold through
underwriters under such registration.

            2.3 Priority on Registrations.

            (a) If the managing underwriter advises the Corporation that the
inclusion of such Restricted Shares would cause a Material Adverse Effect, the
Corporation will be obligated to include in such registration statement, as to
each Stockholder, only a portion of the Restricted Shares such Stockholder has
requested be registered equal to the ratio which such Stockholder's requested
Restricted Shares bears to the total number of Restricted Shares requested to be
included in such registration statement by all Stockholders who have requested
that their Restricted Shares be included in such registration statement, in the
case of Stockholders exercising rights under Section 2.2 hereof. It is
acknowledged by the Stockholders, that pursuant to the foregoing provision, the
securities to be included in such registration shall be allocated (x) if such
registration has been initiated by the Corporation for securities to be offered
by the Corporation, first to the Corporation, second to Stockholders exercising
their piggyback right and third to all others requesting securities to be
included therein and (y) if such registration has been initiated by Requesting
Stockholders requesting a Demand Registration, first to such Requesting
Stockholders, second to the Corporation if it exercises its piggyback right and
third to all others requesting securities to be included therein. If as a result
of the provisions of this Section 2.3(b) any Stockholder shall not be entitled
to include all of its Restricted Shares in a registration that such Stockholder
has requested to be so included, such Stockholder may withdraw such
Stockholder's request to include Restricted Shares in such registration
statement. The Restricted Shares that are excluded from the underwritten public
offering pursuant to the preceding sentence shall be withheld from the market by
the Stockholders for a period, not to exceed 180 days from the closing of such
underwritten public offering, that the managing underwriter determines as
necessary in order to effect such underwritten public offering.

            (b) No Stockholder may participate in any registration statement
hereunder unless such Stockholder completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements, and other documents
reasonably required under the terms of such underwriting arrangements, including
an opinion of its counsel; provided, however, that no such Stockholder shall be
required to make any representations or warranties in connection with any such
registration other than representations and warranties as to (i) such
Stockholder's ownership of its Restricted Shares to be sold or transferred free
and clear of all liens, claims, and encumbrances, (ii) such Stockholder's power
and authority to effect such transfer, and (iii) such matters pertaining to
compliance with securities laws as may be reasonably requested.

            2.4 Registration Procedures. Whenever any Stockholder has requested
that any Restricted Shares be registered pursuant to the provisions of this
Article 2, the Corporation


                                       4
<PAGE>

will use its commercially reasonable efforts to effect the registration and the
sale of such Restricted Shares in accordance with the intended method of
disposition thereof as set forth in the written request, and pursuant thereto
the Corporation shall:

            (a) prepare and file with the Commission registration statement(s)
with respect to such securities on the appropriate forms, and use its best
efforts to cause such registration statement(s) to become and remain effective
in accordance with Section 2.4(b) hereof and in accordance with all laws, rules
and regulations applicable thereto;

            (b) prepare and file with the Commission such amendments and
supplements to such registration statement(s) and the prospectus(es) used in
connection therewith as may be necessary to keep such registration statement(s)
effective until the earlier of (i) the sale of all Restricted Shares covered
thereby or (ii) the date required therefor by the underwriters in the
underwriting agreement, and to comply with the provisions of the Securities Act
with respect to the sale or other disposition of all Restricted Shares covered
by such registration statement(s);

            (c) furnish to each Stockholder participating in such registration
pursuant to Section 2.1 or Section 2.2 (each, a "Participating Stockholder")
such number of copies of any summary prospectus or other prospectus, including a
preliminary prospectus, in conformity with the requirements of the Securities
Act, and such other documents as the Stockholder may reasonably request in order
to facilitate the public sale or other disposition of such Restricted Shares;

            (d) use its best efforts to register or qualify the Restricted
Shares covered by such registration statement(s) under the securities or blue
sky laws of such jurisdictions as the Participating Stockholder shall reasonably
request and do any and all other acts or things which may be necessary or
advisable to enable the Participating Stockholders to consummate the public sale
or other disposition in such jurisdictions of such Restricted Shares; provided,
however, that the Corporation shall not be required to consent to general
service of process for all purposes in any jurisdiction where it is not then
subject to process, qualify to do business as a foreign corporation where it
would not be otherwise required to qualify or submit to liability for state or
local taxes where it is not otherwise liable for such taxes;

            (e) at any time when a prospectus relating thereto covered by such
registration statement(s) is required to be delivered under the Securities Act
within the appropriate period mentioned in Section 2.4(b) hereof, promptly
notify each Stockholder and each underwriter and (if requested by any such
Stockholder) confirm such notice in writing (i) when a prospectus or any
prospectus supplement or post-effective amendment has been filed and, with
respect to a registration statement or any post-effective amendment, when the
same has become effective, (ii) of the issuance by any state securities or other
regulatory authority of any order suspending the qualification or exemption from
qualification of any of the Restricted Shares under state securities or blue sky
laws or the initiation of any proceedings for that purpose, and (iii) 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 in light of the
circumstances then existing and, at the request of any Participating
Stockholder, prepare, file and furnish to such Participating Stockholder a
reasonable number of


                                       5
<PAGE>

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 in the light of the circumstances then
existing;

            (f) if the Corporation has delivered preliminary or final
prospectuses to any Participating Stockholder and after having done so the
prospectus is amended to comply with the requirements of the Securities Act, the
Corporation shall promptly notify such Participating Stockholder and, if
requested, the Participating Stockholder shall immediately cease making offers
of Restricted Shares and return all prospectuses to the Corporation. The
Corporation shall promptly provide the Participating Stockholder with revised
prospectuses and, following receipt of the revised prospectuses, the
Participating Stockholder shall be free to resume making offers of the
Restricted Shares;

            (g) furnish, at the request of the Participating Stockholder on the
date such Restricted Shares are delivered to the underwriters for sale in
connection with a registration pursuant to this Article 2, if such Restricted
Shares are being sold through underwriters, or, if such Restricted Shares are
not being sold through underwriters, on the date that the registration statement
with respect to such Restricted Shares becomes effective, (i) an opinion, dated
such date, of the counsel representing the Corporation for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters, if any, and to
the Participating Stockholders and (ii) a letter dated such date, from the
independent certified public accountants of the Corporation, in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and the Participating Stockholders;

            (h) if any proposed registration effected pursuant to Section 2.1 or
Section 2.2 involves an underwritten public offering, (i) subject to Section
2.1, select a reputable managing underwriter to underwrite such public offering,
(ii) cause all Restricted Shares to be listed for trading on the principal
national securities exchange (including, without limitation, the NASDAQ National
Market System) (as defined in the Securities and Exchange Act of 1934, as
amended) where the Corporation's Stock is listed for trading, and (iii) enter
into (x) an underwriting agreement with the underwriter providing for such
representations, warranties, covenants, conditions and indemnities as may be
requested by the underwriter and (y) a deposit agreement with a depositary, if
applicable, providing for such representations, warranties, covenants,
conditions and indemnities as may be requested by the depositary;

            (i) before filing a registration statement or amendment thereto,
furnish to each Participating Stockholder and its counsel and other
representatives and the underwriters, if any, copies of each such registration
statement or amendment proposed to be filed, which documents shall be made
available on a timely basis for review and comment by the Participating
Stockholders, the underwriters (if any) and their respective representatives;

            (j) make generally available to the Corporation's security holders
an earnings statement satisfying the provisions of Section 11(a) of the
Securities Act, as promptly as


                                       6
<PAGE>

practicable, but in any event no later than forty-five (45) days after the end
of the 12-month period beginning with the first day of the Corporation's first
fiscal quarter commencing after the effective date of a registration statement,
which earnings statement shall cover said 12-month period, and which requirement
will be deemed to be satisfied if the Corporation timely files complete and
accurate information on Forms 20-F and 6-K under the Exchange Act and otherwise
complies with Rule 158 under the Securities Act;

            (k) if requested by the managing underwriter or any Participating
Stockholder, promptly incorporate in a prospectus supplement or post-effective
amendment such information as the managing underwriter or any Participating
Stockholder reasonably requests to be included therein, including, without
limitation, with respect to the Restricted Shares being sold by such
Participating Stockholder, the purchase price being paid therefor by the
underwriters and with respect to any other terms of the underwritten offering of
the Restricted Shares to be sold in such offering, and promptly make all
required filings of such prospectus supplement or post-effective amendment;

            (l) as promptly as practicable after filing with the SEC of any
document which is incorporated by reference into a registration statement (in
the form in which it was incorporated), deliver a copy of each such document to
each Participating Stockholder;

            (m) cooperate with the Participating Stockholders and the managing
underwriter to facilitate the timely preparation and delivery of certificates
(which shall not bear any restrictive legends unless required under applicable
law) representing securities sold under any registration statement (if any), and
enable such securities to be in such denominations and registered in such names
as the managing underwriter or such sellers may request and keep available and
make available to the Corporation's transfer agent prior to the effectiveness of
such registration statement a supply of such certificates;

            (n) promptly make available for inspection by any Participating
Stockholder, any underwriter participating in any disposition pursuant to any
registration statement, and any attorney, accountant or other agent or
representative retained by any such Participating Stockholder or underwriter
(collectively, the "Inspectors"), all financial and other records, pertinent
corporate documents and properties of the Corporation (collectively, the
"Records"), as shall be reasonably necessary to enable them to exercise their
due diligence responsibility, and cause the Corporation's officers, directors
and employees to supply all information requested by any such Inspector in
connection with such registration statement; provided, that, unless the
disclosure of such Records is necessary to avoid or correct a misstatement or
omission in the registration statement or the release of such Records is ordered
pursuant to a subpoena or other order from a court of competent jurisdiction,
the Corporation shall not be required to provide any information under this
subparagraph (n) if (A) the Corporation believes, after consultation with
counsel for the Corporation, that to do so would cause the Corporation to
forfeit an attorney-client privilege that was applicable to such information or
(B) if either (i) the Corporation has requested and been granted from the SEC
confidential treatment of such information contained in any filing with the SEC
of documents provided supplementally or otherwise or (ii) the Corporation
reasonably determines in good faith that such Records are confidential and so
notifies the Inspectors in writing unless prior to furnishing any such
information with respect to (A) or (B) such Participating Stockholder requesting
such information agrees to enter into a


                                       7
<PAGE>

confidentiality agreement in customary form and subject to customary exceptions;
and provided, further, that each Participating Stockholder agrees that it will,
upon learning that disclosure of such Records is sought in a court of competent
jurisdiction, give notice to the Corporation and allow the Corporation at its
expense, to undertake appropriate action and to prevent disclosure of the
Records deemed confidential;

            (o) provide a CUSIP number for the Restricted Shares included in any
registration statement not later than the effective date of such registration
statement;

            (p) cooperate with each Participating Stockholder and each
underwriter participating in the disposition of such Restricted Shares and their
respective counsel in connection with any filings required to be made with the
National Association of Securities Dealers, Inc. ("NASD");

            (q) during the period when the prospectus is required to be
delivered under the Securities Act, promptly file all documents required to be
filed with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the
Exchange Act;

            (r) notify each Participating Stockholder promptly of any request by
the SEC for the amending or supplementing of such registration statement or
prospectus or for additional information;

            (s) prepare and file with the SEC promptly any amendments or
supplements to such registration statement or prospectus which, in the opinion
of counsel for the Corporation or the managing underwriter, is required in
connection with the distribution of the Restricted Shares;

            (t) advise each Participating Stockholder, promptly after it shall
receive notice or obtain knowledge thereof, of the issuance of any stop order by
the SEC suspending the effectiveness of such registration statement or the
initiation or threatening of any proceeding for such purpose and promptly use
its best efforts to prevent the issuance of any stop order or to obtain its
withdrawal at the earliest possible moment if such stop order should be issued;
and

            (u) if the Participating Stockholders so request, to request
acceleration of effectiveness of the registration statement from the Commission,
provided at the time of such request the Corporation does not, in good faith,
believe it is necessary to amend further the registration statement in order to
comply with the provisions of this Section 2.4. If the Corporation wishes to
further amend the registration statement prior to requesting acceleration, it
shall have five (5) business days to so amend prior to requesting acceleration.

            2.5 Suspension of Dispositions. Each Participating Stockholder
agrees that upon receipt of any notice (a "Suspension Notice") from the
Corporation of the happening of any event of the kind described in Section
2.4(e)(iii), such Participating Stockholder will forthwith discontinue
disposition of Restricted Shares until such Participating Stockholder's receipt
of the copies of the supplemented or amended prospectus, or until it is advised
in writing (the "Advice") by the Corporation that the use of the prospectus may
be resumed, and has received copies of any additional or supplemental filings
which are incorporated by reference in the prospectus, and, if so directed by
the Corporation, such Participating Stockholder will deliver to


                                       8
<PAGE>

the Corporation all copies, other than permanent file copies then in such
Participating Stockholder's possession, of the prospectus covering such
Restricted Shares current at the time of receipt of such notice. In the event
the Corporation shall give any such notice, the time period regarding the
effectiveness of registration statements set forth in Section 2.4(b) hereof
shall be extended by the number of days during the period from and including the
date of the giving of the Suspension Notice to and including the date when each
seller of Restricted Shares covered by such registration statement shall have
received the copies of the supplemented or amended prospectus or the Advice. The
Corporation shall use its commercially reasonable efforts and take such actions
as are reasonably necessary to render the Advice as promptly as practicable.

            2.6 Cooperation upon a Registration. The Stockholders and the
Corporation agree that, in connection with any exercise of registration rights
pursuant to this Article 2, the Stockholders will authorize, and will authorize
and direct the Board to take, such actions as are necessary and appropriate to
effectuate such registration. In addition, each Participating Stockholder agrees
to cooperate fully with the Corporation and the underwriters of any underwritten
public offering in the preparation of all documentation necessary or desirable
to effectuate any registration of any Restricted Shares under the Securities Act
pursuant to this Article 2, or registration or qualification of any Restricted
Shares pursuant to Section 2.4(d) hereof. In addition, the Corporation agrees to
cooperate fully with the Participating Stockholders in connection with any such
registration or qualification.

            2.7 Limitations. Notwithstanding anything in this Agreement to the
contrary, if requested in writing by the managing underwriter, if any, of any
underwritten public offering of the Corporation's capital stock pursuant to this
Article 2, each Stockholder agrees not to offer, sell, contract to sell or
otherwise dispose of any shares of capital stock of the Corporation except as
part of such underwritten public offering within thirty (30) days before or one
hundred and eighty (180) days after the effective date of the registration
statement filed with respect to said offering, unless expressly authorized to do
so by the managing underwriter.

            2.8 Expenses. The Corporation shall pay all expenses incurred by the
Corporation in complying with Sections 2.1, 2.2 and 2.4 hereof, including,
without limitation, all registration and filing fees (including all expenses
incident to filing with the NASD), fees and expenses of complying with the
securities or blue sky laws of all such jurisdictions in which the Restricted
Shares are proposed to be offered and sold (including reasonable fees and
disbursements of counsel in connection with blue sky qualification of Restricted
Shares), rating agency fees, printing expenses, messenger and delivery expenses,
the Corporation's internal expenses (including without limitation all salaries
and expenses of its officers and employees performing legal or accounting
duties), fees and expenses incurred in connection with any listing of the
Restricted Shares, fees and expenses of counsel for the Corporation and its
independent certified public accountants (including the expenses of any special
audit or cold comfort letters required by or incident to such performance),
securities act liability insurance (if the Corporation elects to obtain such
insurance) and fees and disbursements of underwriters (to the extent the
Corporation is liable therefor under the terms of any underwriting agreement),
whether or not any registration statement becomes effective; provided, however,
that all underwriting discounts and selling commissions applicable to the
Restricted Shares covered by registrations effected pursuant to Section 2.1 or
Section 2.2 hereof shall be borne by the Participating Stockholders, in
proportion to the number of Restricted Shares sold by each such Participating
Stockholder, and


                                       9
<PAGE>

except as expressly provided in this Section 2.8, in no event shall the
Corporation pay any fees or expenses attributable to any counsel, accountants or
other persons retained or employed by the Participating Stockholders. Further to
the foregoing, the Corporation shall pay all reasonable and customary expenses
incurred by any Participating Stockholder, including, without limitation, all
reasonable expenses and fees of one (1) firm of counsel for all Participating
Stockholders (which shall be selected by a majority (based on the number of
Restricted Securities to be sold) of the Participating Stockholders), plus, to
the extent reasonably necessary, one (1) firm of local counsel for all of the
Participating Stockholders in each state or country where reasonably necessary
(the "Expenses").

            2.9 Indemnification.

            (a) In the event of any registration of any Restricted Shares under
the Securities Act pursuant to this Article 2 or registration or qualification
of any Restricted Shares pursuant to Section 2.4(d) hereof, the Corporation
shall indemnify and hold harmless each Participating Stockholder, each
underwriter of such shares, if any, each broker or any other person acting on
behalf of the Participating Stockholders, each director, officer, employee and
partner of any of the foregoing and each other person, if any, who controls any
of the foregoing persons, within the meaning of the Securities Act (each, an
"Indemnified Person"), against any losses, claims, damages, liabilities or
expenses, joint or several, to which any of the foregoing persons may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of, are related
to, result from or are based upon an untrue statement or alleged untrue
statement of a material fact contained in any registration statement under which
such Restricted Shares were registered under the Securities Act, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereto, or any document incident to registration or qualification of any
Restricted Shares pursuant to Section 2.4(d) hereof, or arise out of, are
related to, result from or are based upon the 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, with respect to any prospectus,
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, or any violation by the Corporation of the
state securities or blue sky laws applicable to the Corporation and relating to
action or inaction required of the Corporation in connection with such
registration or qualification under such state securities or blue sky laws and
the Corporation shall reimburse on demand each Indemnified Person for any legal
or any other costs and expenses reasonably incurred by any of them in connection
with investigating, preparing for, defending or settling any such loss, claim,
damage, liability or action by any governmental agency or body; provided,
however, that the Corporation shall not be liable in any such case to the extent
that any such loss, claim, damage, liability or expense arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in said registration statement, preliminary or final
prospectus or amendment or supplement thereto or any document incident to
registration or qualification of any Restricted Shares pursuant to Section
2.4(d) hereof, in reliance upon and in conformity with written information
furnished to the Corporation by any Participating Stockholder, underwriter,
broker, other person or controlling person specifically for use in the
preparation thereof or arises out of or is based upon the Indemnified Person's
failure to deliver a copy of the registration statement or prospectus or any
amendments or supplements thereto after the Corporation has furnished such
Indemnified Person with a sufficient number of copies of the same; provided
further, that the


                                       10
<PAGE>

Corporation shall not be liable for any settlement made without its prior
written consent, such consent not to be unreasonably withheld.

            (b) Before Restricted Shares shall be included in any registration
pursuant to this Article 2, each Participating Stockholder will furnish to the
Corporation in writing such information and affidavits as the Corporation
reasonably requests for use in connection with any registration statement and
prospectus, and each such Participating Stockholder and any underwriter acting
on its behalf shall have agreed to indemnify and hold harmless (in the same
manner and to the same extent as set forth in paragraph (a) above) the
Corporation, each director of the Corporation, each officer of the Corporation
who signs such registration statement, every other Participating Stockholder and
any person who controls the Corporation within the meaning of the Securities
Act, with respect to any untrue statement or omission from such registration
statement, any preliminary prospectus or final prospectus contained therein, or
any amendment or supplement thereto, if such untrue statement or omission was
made in reliance upon and in conformity with written information furnished to
the Corporation by the Participating Stockholder or such underwriter for use in
the preparation of such registration statement, preliminary prospectus, final
prospectus or amendment or supplement; provided, however, that the maximum
amount of liability in respect of such indemnification shall be limited to an
amount equal to the net proceeds actually received by such Participating
Stockholder from the sale of Restricted Shares effected pursuant to such
registration.

            (c) Promptly after receipt by an indemnified party of notice of the
commencement of any action involving a claim referred to in Section 2.9(a) or
(b) hereof, such indemnified party will, if a claim in respect thereof is to be
made against the indemnifying party under this Section 2.9, give prompt written
notice to the latter of the commencement of such action (provided that the
failure to give such notice shall not limit the rights of such indemnified party
unless and to the extent such failure is prejudicial to its ability to defend
such action). In case any such action is brought against an indemnified party,
the indemnifying party will be entitled to participate in and to assume the
defense thereof, jointly with any other indemnifying party similarly notified to
the extent that it may wish, with counsel reasonably satisfactory to such
indemnified party, and, after notice to such indemnified party from the
indemnifying party of its election to assume the defense thereof; provided,
however, that, if any indemnified party shall have reasonably concluded that
there may be one or more legal defenses available to such indemnified party
which are different from, in conflict with or additional to those available to
the indemnifying party, or that such claim or litigation involves or could
reasonably be expected to have an effect upon matters beyond the scope of the
indemnity agreement provided in this Section 2.9, or if the indemnifying party
fails to take diligent action to defend such claim within twenty (20) days
following notice thereof from the indemnified party, the indemnifying party
shall not have the right to assume the defense of such action on behalf of such
indemnified party, or that such claim or litigation involves or could have an
effect upon matters beyond the scope of the indemnity agreement provided in this
Section 2.9, or if the indemnifying party fails to take diligent action to
defend such claim within twenty (20) days following notice thereof from the
indemnified party, and such indemnifying party shall reimburse such indemnified
party and any person controlling such indemnified party for the fees and
expenses of counsel retained by the indemnified party which are reasonably
related to the matters covered by the indemnity agreement provided in this
Section 2.9. If the indemnifying party does assume its own defense, from such
time the indemnified party shall bear the expenses of its own separate counsel.
If such


                                       11
<PAGE>

defense is not assumed by the indemnifying party as permitted hereunder, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without its written consent, which consent shall not be
unreasonably withheld. If such defense is assumed by the indemnifying party
pursuant to the provisions hereof, such indemnifying party shall not make any
settlement of the applicable claim indemnified against hereunder without the
written consent of the indemnified party or parties, which consent shall not be
unreasonably withheld. An indemnifying party that is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party and any other such indemnified party with respect to such
claim, unless in the reasonable judgment of any indemnified party, a conflict of
interest may exist between such indemnified party with respect to such claim, in
which event the indemnifying party shall be obligated to pay the reasonable fees
and disbursements of such additional counsel or counsels.

            (d) In order to provide for just and equitable contribution to joint
liability under the Securities Act in any case in which an Indemnified Person
makes a claim for indemnification pursuant to this Section 2.9, but it is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced
notwithstanding the fact that this Section 2.9 provides for indemnification in
such case, then the Corporation and the Participating Stockholder will
contribute to the aggregate losses, claims, damages or liabilities to which they
may be subject as is appropriate to reflect, as between the indemnifying party,
on the one hand, and the indemnified party on the other hand, the relative fault
of the indemnifying party, on the one hand, and the indemnified party, on the
other hand, in connection with the statements or omissions which resulted in
such losses, claims, damages or liabilities, it being understood that the
parties acknowledge that the overriding equitable consideration to be given
effect in connection with this provision is the ability of one party or the
other to correct the statement or omission which resulted in such losses,
claims, damages or liabilities, and that it would not be just and equitable if
contribution pursuant hereto were to be determined by pro rata allocation or by
any other method of allocation which does not take into consideration the
foregoing equitable considerations. Notwithstanding the foregoing, (i) the
Participating Stockholder will not be required to contribute any amount in
excess of the proceeds to it of all Restricted Shares sold by it pursuant to
such registration statement, (ii) no underwriter shall be required to contribute
any amount in excess of the proceeds to it from the offering pursuant to such
registration statement, and (iii) no person or entity guilty of fraudulent
misrepresentation, within the meaning of Section 11(f) of the Securities Act,
shall be entitled to contribution from any person or entity who is not guilty of
such fraudulent misrepresentation. If indemnification is available under this
Section 2.9, the indemnifying parties shall indemnify each indemnified party to
the full extent provided in Section 2.9(a) and 2.9(b) without regard to the
relative fault of said indemnifying party or indemnified party or any other
equitable consideration provided for in this Section 2.9(d).

            (e) Notwithstanding any of the foregoing, if in connection with an
underwritten public offering of any Restricted Shares, the Corporation, the
Participating Stockholder and the underwriters enter into an underwriting or
purchase agreement relating to such offering which contains provisions covering
indemnification among the parties, the


                                       12
<PAGE>

indemnification provided thereunder shall be in addition to (and not in lieu of)
the indemnification provided to the Stockholders hereunder.

            (f) The indemnification and contribution required by this Section
2.9 shall be made by periodic payment of the amount thereof during the course of
the investigation or defense, as and when bills are received or expense, loss,
damage or liability is incurred; provided, that if a court of competent
jurisdiction finally determines that any Indemnified Person which has received
payments hereunder does not have an indemnification right under Section 2.9 for
any reason, then such Indemnified Person shall within five (5) days of such
final determination, refund all amounts received hereunder to the Corporation.

            (g) The indemnification and contribution provided for hereunder will
remain in full force and effect regardless of any investigation made by or on
behalf of any Indemnified Person and will survive the transfer of securities.

ARTICLE 3. Miscellaneous

            3.1 Notices. Any and all notices, designations, consents, offers,

or to such other address or telecopier number, as the case may be, as such party
may from time to time designate in writing to the other parties. All such
notices, requests, consents and other communications shall be deemed to have
been received: (a) in the case of personal delivery or registered mail, on the
date of receipt; or (b) in the case of telecopying, on the date of
acknowledgment thereof.

            3.2 Amendment and Waiver. No change or modification of, or waiver of
compliance with, this Agreement shall be valid unless the same shall be in
writing and signed by all of the parties hereto.

            3.3 Termination. This Agreement may be terminated at any time by an
instrument in writing signed by all of the parties hereto. This Agreement shall
terminate automatically as to any Stockholder which transfers all of its
Restricted Shares. Unless sooner terminated, this Agreement shall terminate
eight (8) years from the date hereof, unless, at any time within one (1) year
prior to such date, all of the parties extend its duration for as many
additional periods, each not to exceed eight (8) years, as they may desire.

            3.4 No Waiver. No failure or delay on the part of the Stockholders
or any of them in exercising any right, between the Corporation and the
Stockholders or any of them shall operate as a waiver thereof nor shall any
single or partial exercise of any right, power or privilege hereunder preclude
the simultaneous or later exercise of any other right, power or privilege. The
rights and remedies herein expressly provided are cumulative and not exclusive
of any rights or remedies which the Stockholders or any of them would otherwise
have. No notice to or demand on the Corporation in any case shall entitle the
Corporation to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of


                                       13
<PAGE>

the Stockholders or any of them to take any other or further action in any
circumstances without notice or demand.

            3.5 Specific Performance. Each party to this Agreement acknowledges
that the other parties will suffer irreparable injury in the event of any breach
of any provision of this Agreement and that therefore the remedy at law for any
breach or threatened breach of any such provision of this Agreement will be
inadequate. Accordingly, upon a breach or threatened breach of any such
provision of this Agreement by any party hereto, the other parties shall, in
addition and without prejudice to any of the rights and remedies they may have,
be entitled as a matter of right, without proof of actual damages, to seek
specific performance of such provisions of this Agreement and to such other
injunctive or equitable relief to enforce, or prevent any violations (whether
anticipatory, continuing or future) of, such provisions of this Agreement.

            3.6 Counterparts and Headings. This Agreement may be executed in two
or more counterparts, each of which shall be deemed to be an original, but all
of which together shall constitute one and the same instrument. All headings and
any cover page or table of contents are inserted for convenience or reference
only and shall not affect its meaning or interpretation.

            3.7 Nouns and Pronouns. Whenever the context may require, any
pronouns used herein shall include the corresponding masculine, feminine or
neuter forms, and the singular form of nouns and pronouns shall include the
plural and vice-versa.

            3.8 Expenses. Except as provided in Section 2.8 hereto, each of the
parties to this Agreement shall bear its own expenses, including, without
limitation, the fees and disbursements of its respective counsel, in connection
with the negotiation and execution of this Agreement and the consummation of the
transactions contemplated hereby.

            3.9 Governing Law. This Agreement will be governed by, and construed
and enforced in accordance with, the laws of the State of New York, U.S.A.,
without regard to its conflict of law rules.

            3.10 Submission to Jurisdiction; Consent to Service of Process.

            (a) The parties hereto hereby irrevocably submit to the
non-exclusive jurisdiction of any federal or state court located within the
Borough of Manhattan, State of New York over any dispute arising out of or
relating to this Agreement or any of the transactions contemplated hereby and
each party hereby irrevocably agrees that all claims in respect of such dispute
or any suit, action or proceeding related thereto may be heard and determined in
such courts. The parties hereby irrevocably waive, to the fullest extent
permitted by applicable law, any objection which they may now or hereafter have
to the laying of venue of any such dispute brought in such court or any defense
of inconvenient forum for the maintenance of such dispute. Each of the parties
hereto agrees that a judgment in any such dispute may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

            (b) Each of the parties hereto hereby consents to process being
served by any party to this Agreement in any suit, action or proceeding by the
mailing of a copy thereof in accordance with the provisions of Section 3.1
hereof.

            3.11 Successors and Assigns. This Agreement shall be binding upon
and shall inure to the benefit of the Corporation and its successors, and each
of the Stockholders and their respective executors, administrators and personal
representatives and heirs and their successors and assigns.

            3.12 Severability. In the event that any provision of this Agreement
becomes or is declared by a court of competent jurisdiction to be illegal,
invalid or unenforceable, the remaining provisions hereof shall nevertheless
continue in full force and effect as though the illegal, invalid or
unenforceable provisions were not a part hereof, and the parties shall exert
their best efforts to amend this Agreement to include a provision which is
legal, valid and enforceable and which carries out the original intent of the
parties.

            3.13 Complete Agreement. This Agreement contains the entire
agreement among the parties with respect to the subject matter hereof and
supersedes all prior and contemporaneous arrangements or understandings, whether
written or oral, between or among any of the parties hereto, with respect to the
subject matter hereof.

            3.14 Further Assurances. Each of the parties to this Agreement
agrees to execute such other documents and take such other action as may be
reasonably necessary to implement and carry out the intent of this agreement.

            3.15 Confidentiality. Each Stockholder covenants and agrees to treat
any non-public information provided to it by the Corporation concerning the
business and finances of the Corporation ("Corporate Information") as
confidential and agrees further that it will not use, exploit, reproduce,
disclose or provide Corporate Information to any third party (other than any
agents of the Stockholder who are bound by substantially similar obligations of
confidentiality) on its own behalf or otherwise, except with the consent of the
Corporation or as required by law, legal process or any federal or state
regulatory body having jurisdiction over such Stockholder. The provisions of
this Section 3.15 shall not apply to any information which:

            (a) was within the public domain prior to the time of disclosure of
Corporate Information to the Stockholder or which comes into the public domain
other than as a result of a breach by the Stockholder of this Section 3.15;

            (b) was in the possession of the Stockholder (or any of its
officers, directors, employees, agents, principals, or affiliates) before the
Stockholder received the Corporate Information;

            (c) was rightfully acquired by the Stockholder from a third party
without, to the knowledge of the Stockholder, any restriction or any obligation
of confidentiality; or

            (d) was independently developed by the Stockholder without any use
or reference to the Corporate Information.

            The provisions of this Section 3.15 shall survive the termination of
this Agreement, either in whole or as to any Stockholder, for a period of two
(2) years.

3.16. Failure to Execute. Failure of any party to execute this Agreement renders
this Agreement void as to the non-executing party, but such Agreement shall be
valid and binding as to all other parties that execute such Agreement.

                                                                              21

7.3 - Indemnification Procedure.

      In the case of any claim asserted by a third party against a party
entitled to indemnification under this Agreement (the "Indemnified Party"),
notice shall be given by the Indemnified Party to the indemnifying party (the
"Indemnitor") promptly after such Indemnified Party has actual knowledge of any
claim as to which indemnity may be sought, and the Indemnified Party shall
permit the Indemnitor (at Indemnitor's expense) to assume the defense of any
claim or any litigation resulting therefrom, provided that (i) the counsel for
the Indemnitor who shall conduct the defense of such claim or litigation shall
be reasonably satisfactory to the Indemnified Party, (ii) the Indemnified Party
may participate in such defense at such Indemnified Party's expense, and (iii)
the omission by any Indemnified Party to give notice as provided herein shall
not relieve the Indemnitor of its indemnification obligation under this
Agreement except to the extent that such omission results in a failure of actual
notice to the Indemnitor and the Indemnitor is materially damaged as a result of
such failure to give notice. Except with the prior written consent of the
Indemnified Party, the Indemnitor, in the defense of any such claim or
litigation, shall not consent to

<PAGE>
                                                                              22


entry of any judgment or order, interim or otherwise, or enter into any
settlement that provides for injunctive or other nonmonetary relief affecting
the Indemnified Party or that does not include as an unconditional term thereof
the giving by each claimant or plaintiff to such Indemnified Party of a release
from all liability with respect to such claim or litigation. In the event that
the Indemnified Party shall in good faith determine that the conduct of the
defense of any claim subject to indemnification hereunder or any proposed
settlement of any such claim by the Indemnitor might be expected to affect
adversely the Indemnified Party's tax liability or the ability of the
Indemnified Party or any of its subsidiaries to conduct its business, or that
the Indemnified Party may have available to it one or more defenses or
counterclaims that are inconsistent with one or more of those that may be
available to the Indemnitor in respect of such claim or any litigation relating
thereto, the Indemnified Party shall have the right at all times to take over
and assume control over the defense, settlement, negotiations or litigation
relating to any such claim at the sole cost of the Indemnitor, provided that if
the Indemnified Party does so take over and assume control, the Indemnified
Party shall not settle such claim or litigation without the written consent of
the Indemnitor, such consent not to be unreasonably withheld. In the event that
the Indemnitor does not accept the defense of any matter as above provided, the
Indemnified Party shall have the full right to defend against any such claim or
demand and shall be entitled to settle or agree to pay in full such claim or
demand. Notwithstanding the foregoing, the Indemnitor shall still provide
indemnification to the Indemnified Party. In any event, the Indemnitor and the
Indemnified Party shall cooperate in the defense of any claim or litigation
subject to this Section 7.3 and the records of each shall be available to the
other with respect to such defense.

7.4 - Survival of Indemnification Obligations.

      The obligations of the parties under this Article shall survive the
execution and delivery of this Agreement for a period of not less than five (5)
years.

      5.1   By the present Agreement, IMPSAT will provide to MANDIC

            required for exclusive dial-up access to the Internet, according to

            for the operation and maintenance of the Service.

            responsibilities will be limited to providing maintenance service
            described in Annex D hereof. In case of Service unavailability or
            failure, IMPSAT will use its best efforts to reinstate the Service
            as promptly as possible. MANDIC will be entitled to discounts from

            of Annex D.

            responsible for other damages that MANDIC and/or third parties
            may suffer, including loss of profits, loss of cash resources and/or
            stored properties.

      5.4   IMPSAT is liable for providing MANDIC with the Service specified in
            the Agreement hereof, but in no case it will assure the possibility
            of use or access availability to different services existing in the
            Internet, to which the responsibility will be entirely of the
            providers of each one of such services. IMPSAT will not assume any
            responsibility for the contents, origin, or use of the
            communications, of any type, received or transmitted via Internet.

      5.5   Additionally, and since most of the services and systems comprising
            the Internet are under the responsibility of third parties, IMPSAT
            will not be responsible for transmission speed variations that may
            occur when accessing different servers comprising the web.

laws of the British Virgin Islands and has the corporate power and authority to
own, lease and operate its properties and assets and to carry on its business as
now conducted and as it is proposed to be conducted, except where the lack
thereof would not have a Material Adverse Effect (as defined in Section 9). The
Company is duly qualified or authorized to do business as a foreign corporation
under the laws of each jurisdiction in which the conduct of its business or the
ownership of its properties or assets requires such qualification or
authorization except where the lack thereof would not have a Material Adverse
Effect.

            (b) The authorized and issued capital of the Company immediately
prior to and immediately after the Closing and the legal and beneficial
ownership thereof is as set forth on Schedule 4.1(b). All the outstanding shares
of capital stock of the Company have been duly authorized, and are validly
issued, fully paid and non-assessable. Except as disclosed on Schedule 4.1(b),
(i) there is no option, warrant, call, right, commitment or other agreement of
any character to which the Company is a party, (ii) there are no securities of
the Company outstanding which upon conversion or exchange would require, and
(iii) there are no stock appreciation rights, or other similar rights based on

or other equity securities of the Company or other securities convertible into,


                                       2
<PAGE>

exchangeable for or evidencing the right to subscribe for or purchase shares of
capital stock or other equity securities of the Company. Except as disclosed on
Schedule 4.1(b) and other than this Agreement, the Company is not a party to,
nor is it aware of, any voting trust or other voting agreement with respect to

            4.2 Authorization of Agreement; Enforceability. The Company has all
requisite corporate power and authority to execute and deliver this Agreement
and each other agreement, document, instrument and certificate to be executed by
the Company in connection with the consummation of the transactions contemplated
by this Agreement (the "Transaction Documents"), and to perform fully its
obligations hereunder and thereunder. The execution, delivery and performance by
the Company of this Agreement and the Transaction Documents have been duly
authorized by all necessary corporate action on the part of the Company and its
members. This Agreement and each of the Transaction Documents have been duly and
validly executed and delivered by the Company and, assuming the due
authorization, execution and delivery thereof by the Purchaser, this Agreement
and each of the Transaction Documents constitute the legal, valid and binding
obligations of the Company, enforceable against the Company in accordance with
their respective terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium and similar laws affecting creditors' rights and
remedies generally and subject, as to enforceability, to general principles of

well as each entity in which the Company holds a minority interest. Each
Subsidiary is duly organized and validly existing in good standing (if
applicable) under the laws of the jurisdiction of its incorporation with
corporate power and corporate authority under such laws to own, lease and
operate its properties and conduct its business except, in each case, where the
lack thereof would not have a Material Adverse Effect; and each Subsidiary is
duly qualified to transact business as a foreign corporation and is in good
standing (if applicable) in each other jurisdiction in which it owns or leases
property of a nature, or transacts business of a type, that would make such
qualification necessary, except to the extent that the failure to so qualify or
be in good standing would not result in a Material Adverse Change. All of the
issued and outstanding shares of capital stock of each Subsidiary which are
owned by the Company have been duly authorized and validly issued, and are fully
paid and non-assessable. The Company, directly or indirectly, owns the
percentage of capital indicated in Schedule 4.3(a) next to each such Subsidiary,
free and clear of any Liens, except as set forth in Schedule 4.3(a).

similar arrangement in which the Company or any of its Subsidiaries

filing with, or notification to, any Person or Governmental Body is required on

Agreement or the Transaction Documents, or the compliance by the Company with
any of the provisions hereof or thereof.

leasehold estates in all Real Property Leases in each case free and clear of all
Liens. Neither the Company nor any Subsidiary has any reason to believe that
such title would not be insurable subject to customary exceptions.

            (c) Each of the Real Property Leases is valid and enforceable in
accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium and similar laws affecting creditors' rights and
remedies generally and subject, as to enforceability, to general principles of
equity (regardless of whether enforcement is sought in a proceeding at law or in
equity), and there is no default under any Real Property Lease by the Company or
the applicable Subsidiary or, to the knowledge of the Company, by any other
party thereto, and no event has occurred that with the lapse of time or the
giving of notice or both would constitute a default thereunder. The Company has
delivered or otherwise made available to the Purchaser true, correct and
complete copies of the Real Property Leases, together with all amendments,
modifications, supplements or side letters affecting the obligations of any
party thereunder.

            (d) No previous or current party to any Real Property Lease has
given notice of or made a claim with respect to any breach or default
thereunder. With respect to those Real Property Leases that were assigned or
subleased to the Company or a Subsidiary by a third party, all necessary
consents to such assignments or subleases have been obtained.

            4.11 Tangible Personal Property; Assets. Each of the Company and its
Subsidiaries has good, legal and marketable title to or valid leasehold
interests in, all of its personal property and assets. The personal property
owned by the Company or its Subsidiaries are held in each case free and clear of
all Liens, other than Permitted Liens. With respect to the personal property and
assets that the Company or any Subsidiary leases, the lessee thereunder is in
compliance with such leases except for such noncompliance as would not have a
Material Adverse Effect and the lessee holds a valid leasehold interest free and
clear of any Liens, other than Permitted Liens. All material items of personal
property and assets owned or leased by the Company and its Subsidiaries are in
good operating condition, normal wear and tear excepted.

            4.12 Intangible Property. Each of the Company and its Subsidiaries
owns or possesses adequate licenses or other rights to use all patents, patent
applications, trademarks, trademark applications, service marks, service mark
applications, trade names, copyrights, manufacturing processes, software,
formulae, trade secrets and know how (collectively, "Intellectual Property")
necessary to the conduct of its business as conducted; if any such Intellectual
Property necessary to the conduct of the business as proposed to be conducted is
not owned or licensed to the Company or to any of its Subsidiaries, such
Intellectual Property is readily available to the Company on commercially
reasonable terms, and no claim is pending or, to the knowledge of the Company,
threatened to the effect that the operations of the Company or any Subsidiary
infringe upon or conflict with the asserted rights of any other Person under any
Intellectual Property, and the Company does not know of any basis for any such
claim (whether or not pending or threatened). No claim is pending or, to the
knowledge of the Company, threatened to the effect that any such Intellectual
Property owned or licensed by the Company or any Subsidiary, or which the
Company or a Subsidiary otherwise has the right to use, is invalid or
unenforceable by the Company or the applicable Subsidiary, and the Company does
not know of any basis for any such claim (whether or not pending or threatened).
Neither the Company


                                       8

nor any Subsidiary has granted or assigned to any other Person any right to
provide the services or proposed services of the Company and its Subsidiaries.

full-time employees only; the concepts, inventions and original works of
authorship owned or used by the Company or its Subsidiaries were developed or
conceived by employees within the scope of their employment by the Company (or
the applicable Subsidiary) and are connected with the Company's and its
Subsidiaries' underlying products, processes and proprietary technology. Except

products, processes, proprietary technology and other proprietary know-how owned
or used by the Company and its Subsidiaries.

enforceable against the Company or its Subsidiaries in accordance with its
terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium

conditions established herein, on the Closing Date (i) the Assignor shall assign
to the Assignee the Assigned Contracts, and the Assignee shall acquire from the
Assignor the Assigned Contracts and (ii) the Assignee will pay the Assignor the
Initial Purchase Price (as defined below) in accordance with the terms and
conditions set forth in Section 2.2(a) below.

          (b) The Assignor hereby grants to the Assignee the non-exclusive
right, fully paid, to use the domain name "impsat1.com.ar" in order to allow the
Assignee to continue rendering services exclusively to the Assigned Clients (the
"Dominion"), for a nine month period from the Closing Date. Before the
expiration of said term, the Assignee shall cease to use and cause the Assigned
Clients to cease in the use of the Dominion. Notwithstanding the aforesaid, the
Assignor shall be solely responsible for the lawful administration of the
Dominion during the nine month period referred above.

     2.2 PRICE OF THE ASSIGNMENT. PAYMENT DATES. In consideration for the
assignment of the Assigned Contracts, the Assignee shall pay the Assignor the
Purchase Price. The Purchase Price equals Six Million Two Hundred Thousand U.S.
Dollars (US$6,200,000). Assignee will also be responsible for paying a value
added tax calculated at 21% ("VAT") on the purchase price in the amount of One
Million Three Hundred and Two Thousand U.S. Dollars (US$1,302,000).

The Purchase Price shall be paid by the Assignee to the Assignor as follows:

          (a) 85% of the Purchase Price, i.e. Five Million Two Hundred Seventy
Thousand US Dollars (US $5,270,000) (the "Initial Purchase Price") plus
corresponding VAT equal to One Million One Hundred and Six Thousand Seven
Hundred US Dollars (US$ 1,106,700), shall be paid on the Closing Date by the
Assignee to the Assignor through a wire transfer to account number 3601-8798 at
Citibank N.A. (Beneficiary: IMPSAT S.A.) (ABA #021000089) or as otherwise agreed
to by the Parties.

          (b) the balance of the Purchase Price, i.e. Nine Hundred Thirty
Thousand U.S. Dollars (US$ 930,000) plus the corresponding VAT equal to One
Hundred Ninety Five Thousand Three Hundred U.S. Dollars (US$195,300) shall be
paid by Assignee to Assignor, beginning on December 5, 1999, in 24 equal
consecutive monthly installments plus an annual 12% interest on the balance,
jointly payable with each installment through a deposit in the account to be
specified by the Assignor to the Assignee (hereinafter called the "Balance").
The Balance, or any portion thereof, outstanding at any time may be prepaid by
the Assignee in full at any time without penalty.

          (c) For each day that payment of the Balance is in arrears pursuant to
Section 2.2, the Assignee shall pay to the Assignor interest on loan arrears on
the amount owed at an Annual Effective Rate of 15%.

     2.3 PAYMENT IN US DOLLARS; WAIVER OF THE DOCTRINE OF UNFORESEEABILITY.

          (a) PAYMENT IN US DOLLARS. All the payments shall be made in
unrestricted US Dollars (hereinafter called "Dollars"), free of discounts due to
transfer costs or any other banking expense. If it is legally impossible to buy
Dollars in the Republic of Argentina, the Assignee shall be able to pay with
Dollars bought abroad or with Pesos, or the current Argentine legal currency.
(hereinafter called "Argentine Currency"). The Assignor shall have the exclusive
right to elect one of the following payment options:

                                      -3-

<PAGE>

               (i) exchange rate (bid) of Dollars with Argentine Currency,
pursuant to the quotation of Citibank N.A. at 1:00 p.m. on the payment date,
plus commissions, expenses and taxes on said exchange operation; or

               (ii) the actual amount of Argentine Currency necessary to buy, in
Buenos Aires or Montevideo Republic of Uruguay, at the Assignor's option, the
amount of Foreign Bonds of the Republic of Argentina that sold for Dollars in
New York or Montevideo, at the Assignor's exclusive option, plus any commission,
expense and tax on said operation- is necessary to buy, at 1:00 p.m. of the
effective payment date, the amount owed in Dollars. If this cannot be applied,
the exchange rate to buy Dollars with Argentine Currency in New York or
Montevideo, pursuant to the quotation of Citibank N.A., at 1:00 p.m. on the
effective payment date, will be applied.

          (b) WAIVER OF THE DOCTRINE OF UNFORESEEABILITY. The Parties expressly
agree that the amounts payable pursuant to this Agreement may significantly vary
due to inflationary or hyperinflationary peaks, or due to an increase of taxes
and/or the variation of interest and/or exchange rates, for any reason. These
unforeseeable and important events that may affect the Parties, are a risk for
this Agreement that the Parties accept and, consequently, wholly assume.
Consequently, none of the Parties hereof shall claim either unforeseeability or
contractual adjustments with regard to the agreed amount or currency, nor as a
consequence of the application of economic emergency systems that may affect
what the Parties hereof have freely agreed to pursuant to this Agreement.

     2.4 DELIVERIES. At or before the Closing, the Parties have delivered all
documents required to be delivered by them pursuant to this Agreement or any
other document signed in connection with this Agreement.

     2.5 FRAMEWORK AGREEMENT. The Assignor and the Assignee hereby waive their
rights to an adjustment in the Purchase Price on a per subscriber basis as
contemplated by the Framework Agreement.

agreement shall accrue only if the aggregate amount of such losses exceeds one
percent of the Purchase Price (or $62,000), and the Assignor shall be liable for
all such losses, including such initial one percent amount; provided, however,
that the maximum liability of the Assignor under this Section 8.1 shall not

     8.2 INDEMNIFICATION BY ASSIGNEE. The Assignee shall indemnify and hold
harmless the Assignor and each of its directors, officers, agents, employees,
advisers and representatives from and against any losses, expenses, claims,
damages or liabilities, joint or several, including without limitation

legal counsel to which the Assignor and/or each of its directors, officers,

or are based upon:

          (a) any representation or warranty of the Assignee made herein not
having been materially true, complete and accurate when made;

          (b) any covenant made herein by the Assignee not having been complied
with;

percent of the Purchase Price (or $62,000), and in such event Assignee shall be
liable for all such losses, including such initial one percent amount; provided,
however, that the maximum liability of the Assignee under this Section 8.2 shall
not exceed the Purchase Price. The one percent threshold shall not apply to any
default of the Assignee under Section 2.2(b) of this Agreement, and Assignee

     8.3 INDEMNIFICATION PROCEDURE

          (a) In the case of any claim asserted by a third party against a party
entitled to indemnification under this Agreement (the "Indemnified Party"),
notice shall be given by the Indemnified Party to the indemnifying party (the
"Indemnitor") promptly after such Indemnified Party has actual knowledge of any
claim as to which indemnity may be sought, and the Indemnified Party shall
permit the Indemnitor (at Indemnitor's expense) to assume the defense of any
claim or any litigation resulting therefrom, provided that (i) the counsel for
the Indemnitor who shall conduct the defense of such claim or litigation shall
be reasonably satisfactory to the Indemnified Party, (ii) the Indemnified Party
may participate in such defense at such Indemnified Party's expense, and (iii)
the omission by any Indemnified Party to give notice as provided herein shall
not relieve the Indemnitor of its

                                      -11-

<PAGE>

indemnification obligation under this Agreement except to the extent that such
omission results in a failure of actual notice to the Indemnitor and the
Indemnitor is materially damaged as a result of such failure to give notice.
Except with the prior written consent of the Indemnified Party, the Indemnitor,
in the defense of any such claim or litigation, shall not consent to entry of
any judgment or order, interim or otherwise, or enter into any settlement that
provides for injunctive or other nonmonetary relief affecting the Indemnified
Party or that does not include as an unconditional term thereof the giving by
each claimant or plaintiff to such Indemnified Party of a release from all
liability with respect to such claim or litigation. In the event that the
Indemnified Party shall in good faith determine that the conduct of the defense
of any claim subject to indemnification hereunder or any proposed settlement of
any such claim by the Indemnitor might be expected to affect adversely the
Indemnified Party's tax liability or the ability of the Indemnified Party or any
of its subsidiaries to conduct its business, or that the Indemnified Party may
have available to it one or more defenses or counterclaims that are inconsistent
with one or more of those that may be available to the Indemnitor in respect of
such claim or any litigation relating thereto, the Indemnified Party shall have
the right at all times to take over and assume control over the defense,
settlement, negotiations or litigation relating to any such claim at the sole
cost of the Indemnitor, provided that if the Indemnified Party does so take over
and assume control, the Indemnified Party shall not settle such claim or
litigation without the written consent of the Indemnitor, such consent not to be
unreasonably withheld. In the event that the Indemnitor does not accept the
defense of any matter as above provided, the Indemnified Party shall have the
full right to defend against any such claim or demand and shall be entitled to
settle or agree to pay in full such claim or demand. Notwithstanding the
foregoing, the Indemnitor shall still provide indemnification to the Indemnified
Party. In any event, the Indemnitor and the Indemnified Party shall cooperate in
the defense of any claim or litigation subject to this Section and the records
of each shall be available to the other with respect to such defense.

          (b) The obligations of the parties under this Section shall survive
the execution and delivery of this Agreement for a period of two (2) years.

9.       EXPENSES

                           ANNEX J OPINION OF COUNSEL

                      FORM OF OPINION OF COMPANY'S COUNSEL

Gentlemen:

     This opinion is furnished to you pursuant to Section 6.1(g) of the
Assignment Agreement dated as of , 1999 (the "Agreement") between Impsat S.A.
(the "Assignor") and El Sitio Argentina S.A. (the "Assignee"). Terms defined in
the Agreement are used herein as therein defined.

     We have acted as counsel for the Assignor in connection with the
preparation, execution and delivery of the Agreement.

     In that connection we have examined:

          (1) the Agreement; and

          (2) the corporate documents of the Assignor.

     Based upon the foregoing, we, having regard for legal considerations we
deem relevant, are of the opinion that:

          (a) The Assignor is a company validly existing and in good standing
under the laws of the Republic of Argentina.

          (b) The Agreement is a legal, valid and binding obligation of the
Assignor, enforceable against the Assignor in accordance with its terms, except
to the extent that the enforceability thereof may be subject to bankruptcy,
insolvency, reorganization, moratorium, CONCORDATA, fraudulent conveyance or
other similar laws now or hereafter in effect relating to creditors' rights
generally.

          (c) Except as set forth in the Annexes to the Agreement or otherwise
specified in the Agreement, there are (i) to our knowledge, no material pending
or threatened action, suit, claim, litigation or governmental proceedings or
investigations involving the Acquired Business off any nature, in law or equity;
(ii) no preemptive, contractual or similar rights to purchase or otherwise
acquire the Acquired Business, except pursuant to the Agreement; and (iii) no
liens, pledges, security interest and encumbrances of the Acquired Business
imposed by any Argentine statute, or to our knowledge, any agreement to which
the Assignor is a party or any order of any court or any government agency to
which the Assignor is subject.

          (d) The execution, delivery and performance by the Assignor of the
Agreement, and the compliance with the provisions thereof by the Assignor, do
not:

                                      -26-

<PAGE>

               (i)  Violate to our knowledge any ruling, writ, injunction,
                    order, judgment or decree of any court, administrative
                    agency or other governmental body applicable to the Acquired
                    Business or its properties or assets; or

               (ii) conflict with or result in any breach of any of the terms,
                    conditions or provisions of, or constitute (with due notice
                    or lapse of time, or both) a default (or give rise to any
                    right of termination, cancellation or acceleration) or
                    result in the creation of any lien, security interest,
                    charge or encumbrance upon the Acquired Business under any
                    agreement, document, instrument, contract, note indenture,
                    mortgage or lease to which the Assignor is known by us to be
                    a party or under which the Assignor or any of its assets is
                    known by us to be bound or affected, except for a default
                    under an Assigned Contract.

          (e) Except for the approval required for the ISP License by
[_________], and with respect to (ii) of this paragraph 2(e) any approvals
required under an Assigned Contract, no authorization, consent, approval or
other order of, or declaration to or filing with, any governmental agency or
body, and to our knowledge, no consent, waiver, or authorization under any
agreement, instrument, contract, note, indenture, mortgage or lease to which the
Assignor is known by us to be a party or under which the Assignor or any of
their assets is known by us to be bound or affected, is required for: (i) the
valid authorization, execution, delivery and performance by the Assignor of the
Agreement, or (ii) the valid authorization, sale and delivery of the Acquired
Business, except for the authorization given under the _______ Meeting of the
Assignor held on _________, 1999.

          (f) The Assignor has the necessary corporate power and authority to
own its properties and conduct its businesses as presently conducted, to enter
into the Agreement, and consummate the transactions contemplated thereby.

          (g) All corporate action required by the Assignor in order to
authorize the execution, delivery and performance of the Agreement and the
consummation of the transactions contemplated thereby by the Assignor has been
duly and validly taken.

          (h) The execution and delivery of the Agreement does not violate the
bylaws of the Assignor.

          This opinion is given only as of the date hereof and is addressed only
to and is provided solely for the benefit of the addressees listed herein. It
may not be delivered to or relied upon by any other person without our express
consent, and is strictly limited to the matters stated herein and is not to be

          This opinion is being rendered based on the legal provisions
applicable in Argentina as of the date hereof. We assume no obligation to
supplement this opinion if any applicable law changes after the date hereof or
if we become aware of any facts that might

                                      -27-

             immediate use by EL SITIO, are described in Annex A.

       3.2   For NEW SERVICE ACCESS POINTS and for EXPANSION of the EXISTING
             SERVICE ACCESS POINTS, IMPSAT will provide and install the

             resulting from its fault or deceit.

4.       COVERAGE

       4.1   The area covered by the SERVICES will comprise, initially, the
             locations defined in Annex A.

       4.2   Without any prejudice to this initial coverage, THE PARTIES may
             include, in the Agreement hereof, upon mutual consent,
             successively, cities and areas in which IMPSAT already provides
             dial-up Internet services.


       4.3   IMPSAT will communicate to EL SITIO the incorporation of new
             locations for supply of the SERVICE. At its own discretion, IMPSAT
             will decide on the provision of services in each location.

       4.4   In the event that IMPSAT is not capable of providing the Service in
             a location required by EL SITIO, EL SITIO shall have the right to
             enter into an agreement with another service provider.

5.       IMPSAT'S LIABILITIES AND LIMITS OF RESPONSIBILITY

       5.1   By the present Agreement, IMPSAT will provide to EL SITIO
             installation, management, maintenance, equipment and infrastructure
             services required for exclusive dial-up access to the Internet,
             according to conditions described in Annex B hereof, thus becoming
             responsible for the operation and maintenance of the SERVICE.

       5.2   In case of SERVICE unavailability or failure, IMPSAT's
             responsibilities will be limited to providing maintenance service
             described in Annex D hereof, and to provide EL SITIO with a
             24-hour, 365 days a year telephone service for the solution of
             problems related to the interruption of the Service. In case of
             SERVICE unavailability or failure, IMPSAT will use its best efforts
             to reinstate the SERVICE as promptly as possible. EL SITIO will be
             entitled to discounts from SERVICE payments to IMPSAT
             proportionally to the extent and to the time of unavailability of
             the SERVICE, according to the provisions of Annex D.

       5.3   IMPSAT's responsibilities before EL SITIO will be limited to the
             damages that IMPSAT may cause as a result of the installation,
             management, maintenance, equipment and infrastructure services
             object of this Agreement. Therefore, under no other conditions
             IMPSAT will be responsible for other damages that EL SITIO and/or

<PAGE>

             third parties may suffer, including loss of profits, loss of cash
             resources and/or stored properties.

       5.4   IMPSAT is liable for providing EL SITIO with the SERVICE specified
             in the Agreement hereof, but in no case it will assure the
             possibility of use or access availability to different services
             existing in the Internet, to which the responsibility will be
             entirely of the providers of each one of such services. IMPSAT will
             not assume any responsibility for the contents, origin, or use of
             the communications, of any type, received or transmitted via
             Internet.

       5.5   Additionally, and since most of the services and systems comprising
             the Internet are under the responsibility of third parties, IMPSAT
             will not be responsible for transmission speed variations that may
             occur when accessing different servers comprising the web.

6.       CUSTOMER'S LIABILITIES

             b)  Should IMPSAT provide IP addresses necessary for operation of
                 EL SITIO's internal network, the latter must inform IMPSAT what
                 use has been made of them, every time IMPSAT may so request.

             c)  EL SITIO will exempt IMPSAT from any violation to intellectual
                 property laws, defamation, calumny, and/or any other acts or
                 omissions of EL SITIO, or of any of its customers, which may
                 cause any damages to third parties, through the use of the
                 SERVICE, resulting in liabilities imposed to IMPSAT by any
                 competent court seeking for compensation to such third parties.

             d)  EL SITIO will explain to its customers the adequate computing
                 structure for use of the SERVICE and for its adequate
                 operation, which involves a personal computer, telephone line
                 and modem. The customer will be solely responsible for the
                 maintenace of such computing structure essential for access to
                 the SERVICE.

10.      GENERAL

<PAGE>

       10.1  The entire responsibility related to the services provided by EL
             SITIO to its customers will be of its own liability. EL SITIO will
             also be the sole responsible before its customers in relation to
             providing its services. EL SITIO is forbidden to make any statement
             and/or grant warranties in relation to the services on behalf of
             IMPSAT.

       10.2  THE PARTIES hereby state, in compliance with their contractual
             liabilities, that they will have access to confidential information
             from the other party, such as, but not limiting to working methods,
             marketing plans, prices, list of customers, costs, etc. THE PARTIES
             are committed to maintain this information, or any other to which
             access is provided, under strict confidentiality and using the
             information solely for the purposes of compliance with this
             Agreement. The confidentiality commitment will be maintained for a
             period of two years after the termination of this Agreement, no
             matter what may have caused the termination.

       10.3  IMPSAT agrees to respect and recognize EL SITIO's customers as
             belonging to the latter, thus avoiding any type of business contact
             with them, except in case of written indication or authority for
             such.

       10.4  EL SITIO must not assign rights and liabilities resulting hereof,
             without prior written consent from IMPSAT.

       10.5  EL SITIO will give preference to IMPSAT in contracting the services
             according to the following procedures:

             a)  EL SITIO will notify IMPSAT about services to be contracted,
                 specifying the terms and conditions required to prepare an
                 offer (proposal). IMPSAT will submit to EL SITIO the offer
                 within 10 days as of the reception of such notice.

             b)  Should EL SITIO receive an offer from a third party more
                 favorable than that of IMPSAT, EL SITIO will immediately notify
                 IMPSAT of the terms and conditions contained in such offer.
                 IMPSAT will have the right to match the offer and EL SITIO will
                 then contract the services from IMPSAT.

       10.6  Price adjustment, according to market conditions, may be effected
             after the twelve first months of this Agreement. After twelve
             months, and should EL SITIO receive an offer from a third party
             with more favorable conditions than IMPSAT's, EL SITIO will
             immediately notify IMPSAT about the terms and conditions contained
             in such offer. IMPSAT will have the right to match this offer and
             EL SITIO will then contract or continue to contract the services
             from IMPSAT. Should IMPSAT fail to match or exceed the offer, EL
             SITIO will have the right to terminate this Agreement without any
             penalties.

       10.7  In order to maintain the economic-financial balance of the
             Agreement, EL SITIO expressly agrees, hereafter, to revise the
             prices for the SERVICE to be paid to IMPSAT by the customer, should
             there occur any significant change in the current

<PAGE>

             economic situation of the country, or in the case of any economic
             measure that may significantly devaluate or outdate the agreed
             prices.

       10.8  THE PARTIES shall not assign, transfer or subcontract this
             Agreement or the SERVICES, without the express written
             authorization of the other parties.

11.      SUSPENSION

       11.1  Without any prejudice to any of its other rights, IMPSAT will have
             the right to automatically suspend the SERVICE should EL SITIO fail
             to meet any of its liabilities before the present Agreement, upon
             at least 10 days prior written notice requesting the performance of
             such obligation.

       11.2  Without any prejudice to any of its other rights, EL SITIO will
             have the right to suspend the payment of any amount, under the
             present Agreement, in face of any contractual default by IMPSAT,
             upon at least 10 days prior written notice requesting the
             performance of such obligation.

12.      ACTS OF GOD OR FORCE MAJEURE

       12.1  Any default or delay in its responsibilities regarding equipment
             installation, beginning or continuation of services provided by
             IMPSAT will not generate any liabilities against IMPSAT if such
             default or delay should result from acts of God or force majeure,
             being these understood as acts or facts of the government, natural
             phenomena, or any other circumstances outside IMPSAT's control,

       The dial-up service has the following features:

       -     Modules of 30 telephone channels (ports) via E1 digital trunks when
             available at the location. In some locations, only analog lines are
             available; in others there are analog and digital lines.

       -     Initial capacity for each new POP: 30 ports (channels)

       -     Current capacity for each existing POP: see Annex A

       -     Incrementing modules: 30 ports (channels)

       -     Minimum 4.5 Kbps average connectivity to the backbone for each
             telephone channel (port)

       -     Number of existing POPs = 4

       -     Number of existing dial-up ports = 1,200 (see Annex A)

B.3      SERVICE EXPANSION IN EXISTING POPS

       In case of expansion of the number of ports in the existing IMPSAT's
       POPs, the time for service availability is 30 to 60 days after a formal
       request from EL SITIO to IMPSAT. This time frame depends on facilities
       (telephone infrastructure) available at the site and provided by the
       telephone company.

<PAGE>

Expansion modularity is 30 ports, i.e., E1 trunk modules having 30 telephone
channels.

<PAGE>


B.4      SERVICE EXPANSION IN NEW LOCATIONS (NEW POPs)

       Should EL SITIO need to expand to new locations, or Points of Presence
       (POPs), IMPSAT may provide the services depending on the technical
       availability. Should IMPSAT not be capable of providing the services
       according to conditions and average time established, EL SITIO may freely
       contract the services from other providers.

       The initial modularity will be 30 ports (or one E1 trunk) minimum, and
       expansion in one E1 trunk module (30 ports).

       The time for implementation will be 90 days average, to be confirmed,
       after analysis of technical feasibility by IMPSAT.

                          PRICES AND PAYMENT CONDITIONS


C.1      PRICES

       The prices to be paid by EL SITIO to IMPSAT will be in function of the
       number of ports made available.

       The price is:

       -     $116.88 per month per port

       that is,

       -     $140,256.00 per 1,200 ports

       The prices do not include the Value Added Tax ("VAT"). Prices included in
       this offer are expressed in Argentina Pesos which can be converted
       directly into U.S. Dollars at an exchange rate of U.S. $1/$1, in
       accordance with the provisions of Argentina Convertibility Law No. 23,982
       and taking into consideration the legal force of such Law at the time of
       this offer and its surveillance during the term of this Agreement. In the
       event EL SITIO invoices its customers in U.S. Dollars, the prices indexed
       in this offer will be expressed in U.S. Dollars.

C.2      PAYMENT CONDITIONS

       An amount corresponding to one monthly payment for the contracted
       configuration will be invoiced upon the execution of the Agreement, when
       the SERVICE will already be available at the existing IMPSAT's POPs,
       according to configurations detailed in Annexes A and B.

       The first monthly payment will be invoiced 30 days after execution of the
       Agreement, being due in 5 working days after reception of the invoice by
       EL SITIO. Subsequent payments will be invoiced on a monthly basis, due in
       five working days.

       In case of service expansion, this rule also applies, i.e., upon
       expansion request, a monthly sum will be invoiced relative to such
       expansion, and the first payment after the actuation of the services.
       Subsequent payments will be invoiced on a monthly basis, included in the
       other invoices.

       The payments to be made by EL SITIO to IMPSAT, for any concept as
       established in this Agreement, must be made via bank deposit to a current
       account to be indicated by IMPSAT, or by other means that IMPSAT may
       indicate.

<PAGE>

       In case of delinquency by EL SITIO in meeting any of its payment duties,
       the amounts due will be added of a two percent (2%) fine applied as of
       the next day following the due date of each payment, in addition to one
       percent (1%) interest a month should the delay exceed thirty (30) days,
       calculated as of the day immediately after the due date of the respective
       payment, up to the date of the effective payment. Every payment made by
       EL SITIO, which shall not cover the amount due integrally, the
       corresponding fine, interests and currency update, will be considered
       partial payment. IMPSAT has no obligation to receive partial payments,
       but if it does the amounts received will be imputed first as interests,
       and the due balance, if any, will continue to accumulate interests up to
       its final cancellation. The reception by IMPSAT of any partial payment
       will not imply in delinquency exemption, nor in novation of the
       obligation of EL SITIO.

C.3      CONFIGURATION EXPANSION

       The expansion of the configuration, both for new POPs and expansion of
       the number of dial-up access ports, may be requested during the term of
       the Agreement, with the requested expansion being valid for 12 months,
       i.e., the requested expansions will be a commitment to a minimum term of
       12 months. The price to be charged for new POPs and dial-up access ports
       will be mutually agreed upon by both parties. Each request will result in
       an amendment to the Agreement. For configuration reductions before the
       end of the 12 month period, the same conditions set in section 13.1 will
       apply.

       EL SITIO will deliver to IMPSAT, on a quarterly basis, the estimates for
       growth of the number of new ports required for its customers, in order to
       facilitate the operation of the infrastructure necessary to provide the
       SERVICE at the points of presence.

C.4      PRICE ADJUSTMENT

       Depending on market conditions, specially in relation to prices practiced
       for basic inputs of telephone channels and Internet backbone, the prices
       may be revised, up or down, in 12-month periods.

                                     ANNEX D

                              MAINTENANCE SERVICES


D.1    IMPSAT will directly provide, or by means of an authorized contractor,
       the maintenance services necessary for preserving the infrastructure and
       the equipment in good operating conditions, being understood that it will
       provide for every replacement of spare parts, repairs, and adjustments
       necessary, as resulted of weather exposure, wear and tear from normal and
       proper use, or of defects.

D.2    EL SITIO must inform IMPSAT of any fault immediately after being
       detected, in addition to observing the procedures established to request
       maintenance services. Such event will be communicated orally or by e-mail
       notice.

D.3    As the same manner, IMPSAT shall communicate orally or by e-mail about
       any fault or suspension of the SERVICES within 30 minutes counted from
       its detection.

D.4    IMPSAT reserves the right to check and confirm that the maintenance
       service requested is actually necessary.

D.5    Network preventive and general maintenance will be conducted during
       low-demand hours, being service interruptions notified to EL SITIO at
       least two (2) days before the service. Every unforeseen fault that may
       occur to the network must be repaired by IMPSAT.

D.6    Maintenance service will be provided free of cost to EL SITIO.

D.7    Impossibility of Internet access

       In case EL SITIO or the users of the SERVICES are not able to transmit or
       receive information from the access ports to Internet, in view of a fault
       of the SERVICES rendered by IMPSAT, IMPSAT will credit to EL SITIO the
       proportional amount corresponding to the period that the Services were
       not available, according to the Formula 1 below:

       Such credit will be included in the subsequent invoice to be issued after
       the event.

D.8    Discount Formula in view of unavailability of the SERVICES.

       The interruption period subject to discounts, will be considered due only
       after 30 minutes of continuous interruption, and each complete period of
       30 minutes will be considered for

<PAGE>

       discount purposes. This means that the discount will be due only for
       interruptions which exceeds 30 minutes and for each break of 30 minutes.

       The discount amount will be calculated based on the following manner
       (Formula F.1), per each port affected by the interruption:

       FORMULA F1:

       D = P X H /T

       Where:

       D = amount of the discount per each port
       P = monthly price per each port
       H = number of 30 minutes breaks (completed) interruption
       T = number of 30 minutes in each month = 30 X 24 X 2 = 1440

D.9    SLA - Service Level Agreement

       The SLA - Service Level Agreement will be obtained based on the periods
       of unavailability of the SERVICES, calculated in monthly, trimestrial,
       semestral and annual periods.

       In the calculation of the SERVICE's quality, the non-programmed
       interruptions shall not exceed the following percentages, considering the
       global number of ports:

       In a month:         2.0%
       In a trimester:     1.5%
       In a semester:      1.3%
       In a year:          1.0%

D.10   Audit and Report on Activities

       For follow up and audit purposes, IMPSAT will provide to EL SITIO the
       following reports on:

       -  Internet Backbone Performance
       -  Modems and telephone trunks (E1 or analogical) Performance
       -  Telephone Trunks Occupation

                        RESELLER AND MANAGEMENT AGREEMENT


       THIS RESELLER AND MANAGEMENT AGREEMENT (this "Agreement") is made as of
November 5, 1999, by and between IMPSAT S.A., a company duly created under the
laws of Argentina (the "Assignor"), and El Sitio Argentina S.A., a company duly
created under the laws of Argentina (the "Assignee").

       WHEREAS, pursuant to that certain Assignment Agreement, dated as of the
date hereof (the "Assignment Agreement") between Assignor and Assignee, the
Assignor has agreed to assign the contracts (written and oral) for the provision
of Internet Dial Up access relating to the clients listed on ANNEX C of the
Assignment Agreement;

       WHEREAS, the Assignee has informed the Assignor that it has not yet
obtained certain consents (the "Consents") required to transfer or to obtain the
license (the "ISP License") required to operate the Acquired Business;

       WHEREAS, the Assignee has informed the Assignor that it does not yet have
the capacity and resources to provide certain services with respect to the
Acquired Business;

       WHEREAS, the Assignment Agreement and the Purchase Price that the
Assignee shall pay to the Assignor is a condition for the execution of this
Agreement;

       WHEREAS, the Assignor and the Assignee desire to enter into this
Agreement according to the terms as set forth below; and

       WHEREAS, all capitalized terms used herein and not defined shall have the
meanings ascribed to such terms in the Assignment Agreement.

       NOW, THEREFORE, for the consideration herein stipulated, the parties
hereby agree as follows:

1.       MANAGEMENT OF THE ACQUIRED BUSINESS.

          (a) From and after the Closing Date, the Assignee shall use its best
efforts in seeking the granting by the SECRETARIA DE COMUNICACIONES of the
Republic of Aregentina of the ISP License to Assignee.

          (b) From the Closing Date, the Assignor will render the services set
forth on ANNEX A attached hereto (the "IMPSAT Services") to the Assignee and its
clients included in the Acquired Business and to any other client that Assignee
may incorporate in the future (hereafter referred jointly as the "Assignee
Clients"), until the date which is ninety (90) days after the Closing Date (the
"Services Termination Date"). In addition, the IMPSAT Services specified on
ANNEX B may be rendered for a period greater than ninety (90) days if the ISP
License is not

<PAGE>

received by the Services Termination Date. In such event, the IMPSAT Services
listed on ANNEX B shall be provided until the date such ISP License is received.
Except for the provision of the IMPSAT Services, the Assignor shall have no
other obligation to perform any services for the Assignee pursuant hereto.

          (c) Until the date on which the ISP license is granted to the
Assignee, the parties agree that the Assignee will act as a reseller of the
Services pursuant to Section 5 of the General Licensing Rules approved by
Resolution 16,200 of the Secretary of Communications. During such period the
Assignor shall be responsible to the Assignee Clients for the quality,
reliability and availability of the ISP service and the Assignee will be
responsible for the commercial aspects of the relationship with the Assignee
Clients, including, but not limited to pre- and post-sale activities, customer
services, etc.; provided, however, that the Assignee shall indemnify and hold
harmless the Assignor for all Losses (as defined below) relating to or arising
out of the Acquired Business in accordance with Section 6 hereof

          (d) Until the later of (i) the Services Termination Date and (ii) the
date on which the ISP license is granted to the Assignee, the parties agree that
the Assignee shall have the right to monitor the activities of the Assignor in
providing the IMPSAT Services, provided, however, that Assignee's monitoring of
operations shall not in any way interfere with the Assignor's day-to-day
operation thereof in accordance with this Agreement.

       2. COMPENSATION. As a result of the Assignment Agreement and the Purchase
Price that the Assignee shall pay to Assignor for the Acquired Business, the
Parties mutually agree that as sole consideration for the provision of the
IMPSAT Services, the Assignor will be entitled to all Expenses (as defined
herein) incurred by the Assignor in connection with the provision of the IMPSAT
Services. The Assignor will not be entitled to receive any profit or revenue
arising from the rendering of any services provided by the Assignee to the
Assignee Clients or to any other customers of the Assignee. All amounts payable
to the Assignor pursuant to this Section 2(a) shall be invoiced, due and payable
in accordance with the terms of Clause C2 of Annex C to the Services Agreement
entered into between the Assignor and Assignee, dated as of the date hereof.
Expenses shall include all operating expenses incurred by Assignor, as
calculated in good faith, in conjunction with the provision of the IMPSAT
Services.

       3. RISK OF LOSS. The risk of any loss or damage with respect to the
Acquired Business shall continue to be borne by the Assignee at all times from
the date hereof.

       4. THE ASSIGNOR AS THE AGENT OF THE ASSIGNEE. The Assignor shall perform
the IMPSAT Services hereunder on behalf of the Assignee and shall act solely as
the agent of the Assignee. Neither party hereto shall have any right or
authority to bind the other or to incur or create any liability for or on behalf
of the other.

       5. TERM OF AGREEMENT; EFFECT OF TERMINATION. This Agreement shall
continue in full force and effect until the later of (i) the Services
Termination Date and (ii) the date on which the ISP license is granted to the
Assignee. The Assignee shall pay to the Assignor within 10 days of termination
of this Agreement all outstanding amounts due under Section 2 for the period
prior to the termination of this Agreement.

settlements, including, without limitation, any claims, damage or liabilities

benefit of the heirs, successors and administrators of the Indemnitee.

Assignor's gross negligence, fraud or willful misconduct in connection with the
performance (or failure to perform) by the Assignor of this Agreement.

benefit of the Assignee's heirs, successors and administrators.

          (d) The provisions of this Section 7 are for the benefit of the
Assignee and its affiliates and shall not be deemed to create any rights for the
benefit of any other persons.

          (e) The indemnification obligations of the Assignor set forth in this

written consent of the other Party.

       9. WAIVER. No waiver of any term, provision, or condition of this

provision shall not affect any other provision of this Agreement, which shall
remain in full force and effect to the extent possible.

any character to which the Company is a party, (ii) there are no securities of

standing (if applicable) under the laws of the jurisdiction of its incorporation

and each Subsidiary is duly qualified to transact business as a foreign
corporation and is in good standing (if applicable) in each other jurisdiction
in which it owns or leases property of a nature, or transacts business of a

Subsidiaries participates. 4.4 CONSENTS OF THIRD PARTIES. None of the execution
and delivery by the Company of this Agreement and the Transaction Documents, the

with, or result in the breach of, any provision of the Memorandum of Association
or Articles of Association of the Company, (b) conflict with, violate, result in

         In consideration of the purchase by Intel Atlantic, Inc. ("Intel") of
555,555.55 shares of Class B Preferred Stock of El Sitio, Inc. ("Company"),
pursuant to a Share Purchase Agreement dated November 9, 1999 (the "Purchase
Agreement"), Company and Intel agree to the terms and obligations of this letter
agreement ("Agreement").

1.       CONFIDENTIALITY

         (a) DISCLOSURE OF TERMS. The terms and conditions of this Agreement,
the Purchase Agreement, the Amended and Restated Shareholders Agreement, dated
November 9, 1999 and the Amended and Restated Registration Rights Agreement,
dated November 9, 1999 (collectively, the "Financing Terms"), including their
existence, shall be considered confidential information and shall not be
disclosed by the Company to any third party except in accordance with the
provisions set forth below.

         (b) PRESS RELEASES, ETC. Within sixty (60) days after the closing of
the transactions contemplated by the Purchase Agreement, the Company may issue a
press release disclosing that the Investors, including Intel, have invested in
the Company; provided that the release does not disclose any of the Financing
Terms and the final form of the press release is approved in advance in writing
by Intel. Intel's name and the fact that Intel is an investor in the Company can
be included in a reusable press release boilerplate statement, so long as Intel
has given the Company its initial approval of such boilerplate statement and the
boilerplate statement is reproduced in exactly the form in which it was
approved. No other announcements regarding Intel in a press release, conference,
advertisement, announcement, professional or trade publication, mass marketing
materials or otherwise to the general public may be made without Intel's prior
written consent.

         (c) PERMITTED DISCLOSURES. Notwithstanding the foregoing, (i) the
Company may disclose any of the Financing Terms to its current or bona fide
prospective investors, employees, investment bankers, lenders, accountants and
attorneys, in each case only where such persons or entities are under
appropriate nondisclosure obligations; (ii) the Company may disclose (other than
in a press release or other public announcement described in subsection (b))
solely the fact that Intel is an investor in the Company to any third parties
without the requirement for the consent of any other party or nondisclosure
obligations; and (iii) Intel may disclose its investment in the Company and the
Financing Terms to third parties or to the public at its sole discretion and, if
it does so, the Company shall have the right to disclose to third parties any
such information disclosed in a press release or other public announcement by
Intel.


                  [Signature Page to Share Purchase Agreement]
<PAGE>

         (d) LEGALLY COMPELLED DISCLOSURE. In the event that any party is
requested or becomes legally compelled (including without limitation, pursuant
to securities laws and regulations) to disclose the existence of the agreements
referenced in paragraph (a) above or any of the Financing Terms hereof in
contravention of the provisions of this letter, the Company shall provide Intel
with prompt written notice of that fact so that the appropriate party may seek
(with the cooperation and reasonable efforts of the other) a protective order,
confidential treatment or other appropriate remedy. In such event, the Company
shall furnish only that portion of the information which is legally required and
shall exercise reasonable efforts to obtain reliable assurance that confidential
treatment will be accorded such information to the extent reasonably requested
by Intel.

         (e) OTHER INFORMATION. The provisions of this Letter Agreement shall be
in addition to, and not in substitution for, the provisions of any separate
nondisclosure agreement executed by any of the parties hereto with respect to
the transactions contemplated hereby. Additional disclosures and exchange of

ARTICLE 2.        Registration Rights

                  2.1 DEMAND REGISTRATION.

                  (a) Upon notice to the Company (x) from Shareholder(s) holding
in the aggregate $15.0 million or more of the Restricted Shares (or Preferred
Shares which are convertible into Restricted Shares) or (y) Class B
Shareholder(s) holding in the aggregate $5.0 million or more of the Restricted
Shares (or Preferred Shares which are convertible into Restricted Shares), such
Shareholders (the "Requesting Shareholders") shall have the right to request in
writing a registration of such shares that are (or which would be upon
conversion) Restricted Shares. Such request (a "Demand Request") by the
Requesting Shareholders shall (i) specify the number of Restricted Shares which
each Requesting Shareholder intends to sell or dispose of, and (ii) state the
intended method or methods by which the Requesting Shareholder intends to sell
or dispose of such Restricted Shares. Upon receipt of a Demand Request pursuant
to this Section 2.1, the Company shall (as requested) (i) cause to be filed,
within the later of (x) ninety (90) days of the date of delivery to the Company
of the Demand Request, or (y) one hundred eighty (180) days after the
effectiveness of the most recently filed registration statement by the Company,
a registration statement covering such Restricted Shares which the Company has
been so requested



                                       2
<PAGE>



to register, providing for the registration under the Securities Act of such
Restricted Shares to the extent necessary to permit the disposition of such
Restricted Shares so to be registered in accordance with the intended method of
distribution specified in such Demand Request, provided, that the Company may
delay making such filing or taking such action by not more than one hundred
twenty (120) days if the Company, prior to the time it would otherwise have been
required to file such registration statement or take such action, determines in
good faith that the filing of such registration statement or the taking of such
action would require the disclosure of material, non-public information that, in
the reasonable judgment of the Company, would be detrimental to the Company if
so disclosed (and a delay would be likely to reduce the detrimental effect of
such disclosure or obviate the need for such disclosure to be made, or would
otherwise adversely affect a financing, acquisition, disposition, merger or
other material transaction), (ii) shall use its best efforts to have such
registration statement declared effective by the Commission as soon as
practicable thereafter, and (iii) refrain from filing any other registration
statements with respect to any other securities of the Company until such date
which is one hundred eighty (180) days following effectiveness of the
registration statement filed in response to the Demand Request. Subject to any
existing written agreement between the Company and Bear, Stearns & Co. Inc., the
underwriter shall be selected by the Requesting Shareholders and shall be
reasonably acceptable to the Company for any registration pursuant to this
Section 2.1.

                  (b) In the event that the Company is required to file a
registration statement covering any Restricted Shares of any Requesting
Shareholder(s) pursuant to Section 2.1(a) above, the Company shall be permitted
to include newly-issued securities ("Piggyback Securities") in such
registration. Notwithstanding the foregoing, if the managing underwriter of such
proposed registration determines and advises in writing that the inclusion of
all Piggyback Securities proposed to be included in the underwritten public
offering would interfere with the successful marketing of the Requesting
Shareholders' Restricted Shares, then the Company shall not be permitted to
include any Piggyback Securities in excess of the amount, if any, of Piggyback
Securities which the managing underwriter of such underwritten offering shall
reasonably and in good faith agree in writing to include in such offering in
excess of any amount to be registered for the Requesting Shareholder(s). The
Piggyback Securities that are excluded from the underwritten public offering
pursuant to the preceding sentence shall be withheld from the market by the
Company for a period, not to exceed 90 days from the closing of such
underwritten public offering, that the managing underwriter determines is
necessary in order to effect such underwritten public offering.

                  (c) The Company shall not be required to comply with more than
four (4) Demand Requests, one (1) of which shall be reserved for IAMP (El Sitio)
Investments Ltd. (and its affiliates), one (1) of which shall be reserved for
IMPSAT Corporation, one (1) of which shall be reserved for the Initial
Shareholders, and one (1) of which shall be reserved for the Class B
Shareholders holding a majority of the Class B Preferred Shares or Restricted
Shares issued upon conversion of Class B Preferred Shares; provided, that the
Class B Shareholders and the Class A Shareholders shall each have two (2) Demand
Rights per annum commencing at such time as the Company becomes eligible to
register its Common Shares on Form F-3, for so long as the Company remains, or
at any time the Company is, so eligible.

                  2.2 PIGGYBACK REGISTRATION.

                  (a) Each time that the Company proposes for any reason to
register any of its Stock under the Securities Act (a "Proposed Registration"),
other than pursuant to a registration statement on Form F-4 or Form F-8 or
similar or successor forms, the Company shall promptly give written notice of
such Proposed Registration to the holders of the Restricted Shares (which notice
shall be given not less than thirty (30) days prior to the expected effective
date of the Company's registration statement) and shall offer such holders the
right to request inclusion of any of such holder's Restricted Shares in the
Proposed Registration. No registration pursuant to this Section 2.2 shall
relieve the Company of its obligation to register Restricted Shares pursuant to
Section 2.1.

                  (b) Each Shareholder shall have twenty (20) days from the
receipt of such notice to deliver to the Company a written request specifying
the number of Restricted Shares such Shareholder intends to sell and such
Shareholder's intended method of disposition. Any Shareholder shall have the
right to withdraw such Shareholder's request for inclusion of such Shareholder's
Restricted Shares in any registration statement pursuant to this Section 2.2 by
giving written notice to the Company of such withdrawal. Subject to Section 2.3
below, the Company shall include in such registration statement all such
Restricted Shares so requested to be included therein; provided, however, that
the Company may at any time withdraw or cease proceeding with any such Proposed
Registration if it shall at the same time withdraw or cease proceeding with the
registration of all other equity securities originally proposed to be
registered.

                  (c) In the event that the Proposed Registration by the Company
is, in whole or in part, an underwritten public offering of securities of the
Company, any request under Section 2.2(b) hereof must specify that the
Restricted Shares be included in the underwriting on the same terms and
conditions as the shares of Stock, if any, otherwise being sold through
underwriters under such registration.

                  2.3 PRIORITY ON REGISTRATIONS.

                  (a) If the managing underwriter advises the Company that the
inclusion of such Restricted Shares would cause a Material Adverse Effect, the
Company will be obligated to include in such registration statement, as to each
Shareholder, only a portion of the Restricted Shares such Shareholder has
requested be registered equal to the ratio which such Shareholder's requested
Restricted Shares bears to the total number of Restricted Shares requested to be
included in such registration statement by all Shareholders who have requested
that their Restricted Shares be included in such registration statement, in the
case of Shareholders exercising rights under Section 2.2 hereof. It is
acknowledged by the Shareholders, that pursuant to the foregoing provision, the
securities to be included in such registration shall be allocated (x) if such
registration has been initiated by the Company for securities to be offered by
the Company, first to the Company, second to Shareholders exercising their
piggyback right and third to all others requesting securities to be included
therein and (y) if such registration has been initiated by a Requesting
Shareholder requesting a Demand Registration, first to such Requesting
Shareholder, second to the Company if it exercises its piggyback right and third
to all others requesting securities to be included therein. If as a result of
the provisions of this Section 2.3(a) any Shareholder shall not be entitled to
include all of its Restricted Shares in a registration that



                                       4
<PAGE>

such Shareholder has requested to be so included, such Shareholder may withdraw
such Shareholder's request to include Restricted Shares in such registration
statement. The Restricted Shares that are excluded from the underwritten public
offering pursuant to the preceding sentence shall be withheld from the market by
the Shareholders for the applicable period set forth in Section 2.7, if the
managing underwriter determines it necessary in order to effect such
underwritten public offering.

                  (b) No Shareholder may participate in any registration
statement hereunder unless such Shareholder completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements, and
other documents reasonably required under the terms of such underwriting
arrangements, including an opinion of its counsel; provided, however, that no
such Shareholder shall be required to make any representations or warranties in
connection with any such registration other than representations and warranties
as to (i) such Shareholder's ownership of its Restricted Shares to be sold or
transferred free and clear of all liens, claims, and encumbrances, (ii) such
Shareholder's power and authority to effect such transfer, and (iii) such
matters pertaining to compliance with securities laws as may be reasonably
requested.

                  2.4 REGISTRATION PROCEDURES. Whenever any Shareholder has
requested that any Restricted Shares be registered pursuant to the provisions of
this Article 2, the Company will use its commercially reasonable efforts to
effect the registration and the sale of such Restricted Shares in accordance
with the intended method of disposition thereof as set forth in the written
request, and pursuant thereto the Company shall:

                  (a) prepare and file with the Commission registration
statement(s) with respect to such securities on the appropriate forms, and use
its best efforts to cause such registration statement(s) to become and remain
effective in accordance with Section 2.4(b) hereof and in accordance with all
laws, rules and regulations applicable thereto;

                  (b) prepare and file with the Commission such amendments and
supplements to such registration statement(s) and the prospectus(es) used in
connection therewith as may be necessary to keep such registration statement(s)
effective until the earlier of (i) the sale of all Restricted Shares covered
thereby or (ii) the date required therefor by the underwriters in the
underwriting agreement, and to comply with the provisions of the Securities Act
with respect to the sale or other disposition of all Restricted Shares covered
by such registration statement(s);

                  (c) furnish to each Shareholder participating in such
registration pursuant to Section 2.1 or Section 2.2 (each, a "Participating
Shareholder") such number of copies of any summary prospectus or other
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as the Shareholder
may reasonably request in order to facilitate the public sale or other
disposition of such Restricted Shares;

                  (d) use its best efforts to register or qualify the Restricted
Shares covered by such registration statement(s) under the securities or blue
sky laws of such jurisdictions as the Participating Shareholder shall reasonably
request and do any and all other acts or things which may be necessary or
advisable to enable the Participating Shareholders to consummate the public sale
or other disposition in such jurisdictions of such Restricted Shares; provided,
however, that



                                       5
<PAGE>

the Company shall not be required to consent to general service of process for
all purposes in any jurisdiction where it is not then subject to process,
qualify to do business as a foreign Company where it would not be otherwise
required to qualify or submit to liability for state or local taxes where it is
not otherwise liable for such taxes;

                  (e) at any time when a prospectus relating thereto covered by
such registration statement(s) is required to be delivered under the Securities
Act within the appropriate period mentioned in Section 2.4(b) hereof, promptly
notify each Shareholder and each underwriter and (if requested by any such
Shareholder) confirm such notice in writing (i) when a prospectus or any
prospectus supplement or post-effective amendment has been filed and, with
respect to a registration statement or any post-effective amendment, when the
same has become effective, (ii) of the issuance by any state securities or other
regulatory authority of any order suspending the qualification or exemption from
qualification of any of the Restricted Shares under state securities or blue sky
laws or the initiation of any proceedings for that purpose, and (iii) 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 in light of the
circumstances then existing and, at the request of any Participating
Shareholder, prepare, file and furnish to such Participating Shareholder 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 in the light
of the circumstances then existing;

                  (f) if the Company has delivered preliminary or final
prospectuses to any Participating Shareholder and after having done so the
prospectus is amended to comply with the requirements of the Securities Act, the
Company shall promptly notify such Participating Shareholder and, if requested,
the Participating Shareholder shall immediately cease making offers of
Restricted Shares and return all prospectuses to the Company. The Company shall
promptly provide the Participating Shareholder with revised prospectuses and,
following receipt of the revised prospectuses, the Participating Shareholder
shall be free to resume making offers of the Restricted Shares;

                  (g) furnish, at the request of the Participating Shareholder
on the date such Restricted Shares are delivered to the underwriters for sale in
connection with a registration pursuant to this Article 2, if such Restricted
Shares are being sold through underwriters, or, if such Restricted Shares are
not being sold through underwriters, on the date that the registration statement
with respect to such Restricted Shares becomes effective, (i) an opinion, dated
such date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters, if any, and to
the Participating Shareholders and (ii) a letter dated such date, from the
independent certified public accountants of the Company, in form and substance
as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and the Participating Shareholders;

<PAGE>

                  (h) if any proposed registration effected pursuant to Section
2.1 or Section 2.2 involves an underwritten public offering, (i) subject to
Section 2.1, select a reputable managing underwriter to underwrite such public
offering, (ii) cause all Restricted Shares to be listed for trading on the
principal national securities exchange (including, without limitation, the
NASDAQ National Market System) (as defined in the Securities and Exchange Act of
1934, as amended) where the Company's Stock is listed for trading, and (iii)
enter into (x) an underwriting agreement with the underwriter providing for such
representations, warranties, covenants, conditions and indemnities as may be
requested by the underwriter and (y) a deposit agreement with a depositary, if
applicable, providing for such representations, warranties, covenants,
conditions and indemnities as may be requested by the depositary;

                  (i) before filing a registration statement or amendment
thereto, furnish to each Participating Shareholder and its counsel and other
representatives and the underwriters, if any, copies of each such registration
statement or amendment proposed to be filed, which documents shall be made
available on a timely basis for review and comment by the Participating
Shareholders, the underwriters (if any) and their respective representatives;

                  (j) make generally available to the Company's security holders
an earnings statement satisfying the provisions of Section 11(a) of the
Securities Act, as promptly as practicable, but in any event no later than
forty-five (45) days after the end of the 12-month period beginning with the
first day of the Company's first fiscal quarter commencing after the effective
date of a registration statement, which earnings statement shall cover said
12-month period, and which requirement will be deemed to be satisfied if the
Company timely files complete and accurate information on Forms 20-F and 6-K
under the Exchange Act and otherwise complies with Rule 158 under the Securities
Act;

                  (k) if requested by the managing underwriter or any
Participating Shareholder, promptly incorporate in a prospectus supplement or
post-effective amendment such information as the managing underwriter or any
Participating Shareholder reasonably requests to be included therein, including,
without limitation, with respect to the Restricted Shares being sold by such
Participating Shareholder, the purchase price being paid therefor by the
underwriters and with respect to any other terms of the underwritten offering of
the Restricted Shares to be sold in such offering, and promptly make all
required filings of such prospectus supplement or post-effective amendment;

to each Participating Shareholder;

<PAGE>

                  (n) promptly make available for inspection by any

agent or representative retained by any such Participating Shareholder or
underwriter (collectively, the "Inspectors"), all financial and other records,
pertinent corporate documents and properties of the Company (collectively, the
"Records"), as shall be reasonably necessary to enable them to exercise their
due diligence responsibility, and cause the Company's officers, directors and
employees to supply all information requested by any such Inspector in
connection with such registration statement; provided, that, unless the
disclosure of such Records is necessary to avoid or correct a misstatement or
omission in the registration statement or the release of such Records is ordered
pursuant to a subpoena or other order from a court of competent jurisdiction,
the Company shall not be required to provide any information under this
subparagraph (n) if (A) the Company believes, after consultation with counsel
for the Company, that to do so would cause the Company to forfeit an
attorney-client privilege that was applicable to such information or (B) if
either (i) the Company has requested and been granted from the SEC confidential
treatment of such information contained in any filing with the SEC of documents
provided supplementally or otherwise or (ii) the Company reasonably determines

customary exceptions; and provided, further, that each Participating Shareholder
agrees that it will, upon learning that disclosure of such Records is sought in
a court of competent jurisdiction, give notice to the Company and allow the
Company at its expense, to undertake appropriate action and to prevent
disclosure of the Records deemed confidential;

                  (o) provide a CUSIP number for the Restricted Shares included

                  (s) prepare and file with the SEC promptly any amendments or
supplements to such registration statement or prospectus which, in the opinion
of counsel for the Company or the managing underwriter, is required in
connection with the distribution of the Restricted Shares;



                                       8
<PAGE>

                  (t) advise each Participating Shareholder, promptly after it
shall receive notice or obtain knowledge thereof, of the issuance of any stop
order by the SEC suspending the effectiveness of such registration statement or
the initiation or threatening of any proceeding for such purpose and promptly
use its best efforts to prevent the issuance of any stop order or to obtain its
withdrawal at the earliest possible moment if such stop order should be issued;
and

                  (u) if the Participating Shareholders so request, to request
acceleration of effectiveness of the registration statement from the Commission,
provided at the time of such request the Company does not, in good faith,
believe it is necessary to amend further the registration statement in order to
comply with the provisions of this Section 2.4. If the Company wishes to further
amend the registration statement prior to requesting acceleration, it shall have
five (5) business days to so amend prior to requesting acceleration.

                  2.5 SUSPENSION OF DISPOSITIONS. Each Participating Shareholder
agrees that upon receipt of any notice (a "Suspension Notice") from the Company
of the happening of any event of the kind described in Section 2.4(e)(iii), such
Participating Shareholder will forthwith discontinue disposition of Restricted
Shares until such Participating Shareholder's receipt of the copies of the
supplemented or amended prospectus, or until it is advised in writing (the
"Advice") by the Company that the use of the prospectus may be resumed, and has
received copies of any additional or supplemental filings which are incorporated
by reference in the prospectus, and, if so directed by the Company, such
Participating Shareholder will deliver to the Company all copies, other than
permanent file copies then in such Participating Shareholder's possession, of
the prospectus covering such Restricted Shares current at the time of receipt of
such notice. In the event the Company shall give any such notice, the time
period regarding the effectiveness of registration statements set forth in
Section 2.4(b) hereof shall be extended by the number of days during the period
from and including the date of the giving of the Suspension Notice to and
including the date when each seller of Restricted Shares covered by such
registration statement shall have received the copies of the supplemented or
amended prospectus or the Advice. The Company shall use its commercially
reasonable efforts and take such actions as are reasonably necessary to render
the Advice as promptly as practicable.

                  2.6 COOPERATION UPON A REGISTRATION. The Shareholders and the
Company agree that, in connection with any exercise of registration rights
pursuant to this Article 2, the Shareholders will authorize, and will authorize
and direct the Board to take, such actions as are necessary and appropriate to
effectuate such registration. In addition, each Participating Shareholder agrees
to cooperate fully with the Company and the underwriters of any underwritten
public offering in the preparation of all documentation necessary or desirable
to effectuate any registration of any Restricted Shares under the Securities Act
pursuant to this Article 2, or registration or qualification of any Restricted
Shares pursuant to Section 2.4(d) hereof. In addition, the Company agrees to
cooperate fully with the Participating Shareholders in connection with any such
registration or qualification.

                  2.7 LIMITATIONS. Notwithstanding anything in this Agreement to
the contrary, if requested in writing by the managing underwriter, if any, of
any underwritten public offering of the Company's capital stock pursuant to this
Article 2, each Shareholder agrees not to offer, sell, contract to sell or
otherwise dispose of any shares of capital stock of the Company except as part
of such underwritten public offering within thirty (30) days before or (i)
ninety (90) days after



                                       9
<PAGE>

the effective date of the registration statement filed with respect to said
offering, and (ii) one hundred eighty (180) days in the case of the Company's
initial public offering, unless in each case expressly authorized to do so by
the managing underwriter; provided, however, that if any officer, director or
shareholder holding 5% or more of the share capital of the Company is not
obligated under this Section 2.7 or a similar provision in another agreement, or
if any such person is released from its obligations under this Section 2.7 or
such other agreement, and accordingly is entitled to sell its shares within the
periods set forth above, then each Class A Shareholder and each Class B
Shareholder shall also be entitled to sell a pro rata amount of its shares in
proportion to the ratio that the number of shares held by such persons that are
not obligated under this Section 2.7 or a similar provision in another agreement
or is otherwise released from such obligation bears to the total number of
shares subject to such obligation.

                  2.8 EXPENSES. The Company shall pay all expenses incurred by
the Company in complying with Sections 2.1, 2.2 and 2.4 hereof, including,
without limitation, all registration and filing fees (including all expenses
incident to filing with the NASD), fees and expenses of complying with the
securities or blue sky laws of all such jurisdictions in which the Restricted
Shares are proposed to be offered and sold (including reasonable fees and
disbursements of counsel in connection with blue sky qualification of Restricted
Shares), rating agency fees, printing expenses, messenger and delivery expenses,
the Company's internal expenses (including without limitation all salaries and
expenses of its officers and employees performing legal or accounting duties),
fees and expenses incurred in connection with any listing of the Restricted
Shares, fees and expenses of counsel for the Company and its independent
certified public accountants (including the expenses of any special audit or
cold comfort letters required by or incident to such performance), securities
act liability insurance (if the Company elects to obtain such insurance) and
fees and disbursements of underwriters (to the extent the Company is liable
therefor under the terms of any underwriting agreement), whether or not any
registration statement becomes effective; provided, however, that all
underwriting discounts and selling commissions applicable to the Restricted
Shares covered by registrations effected pursuant to Section 2.1 or Section 2.2
hereof shall be borne by the Participating Shareholders, in proportion to the
number of Restricted Shares sold by each such Participating Shareholder, and
except as expressly provided in this Section 2.8, in no event shall the Company
pay any fees or expenses attributable to any counsel, accountants or other
persons retained or employed by the Participating Shareholders. Further to the
foregoing, the Company shall pay all reasonable and customary expenses incurred
by any Participating Shareholder, including, without limitation, all reasonable
expenses and fees of one (1) firm of counsel for all Participating Shareholders
(which shall be selected by a majority (based on the number of Restricted
Securities to be sold) of the Participating Shareholders), plus, to the extent
reasonably necessary, one (1) firm of local counsel for all of the Participating
Shareholders in each state or country where reasonably necessary (the
"Expenses").

                  2.9 INDEMNIFICATION.

                  (a) In the event of any registration of any Restricted Shares
under the Securities Act pursuant to this Article 2 or registration or
qualification of any Restricted Shares pursuant to Section 2.4(d) hereof, the
Company shall indemnify and hold harmless each Participating Shareholder, each
underwriter of such shares, if any, each broker or any other person acting on
behalf of the Participating Shareholders, each director, officer, employee and




                                       10
<PAGE>

partner of any of the foregoing and each other person, if any, who controls any
of the foregoing persons, within the meaning of the Securities Act (each, an
"Indemnified Person"), against any losses, claims, damages, liabilities or
expenses, joint or several, to which any of the foregoing persons may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of, are related
to, result from or are based upon an untrue statement or alleged untrue
statement of a material fact contained in any registration statement under which
such Restricted Shares were registered under the Securities Act, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereto, or any document incident to registration or qualification of any
Restricted Shares pursuant to Section 2.4(d) hereof, or arise out of, are
related to, result from or are based upon the 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, with respect to any prospectus,
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, or any violation by the Company of the
state securities or blue sky laws applicable to the Company and relating to
action or inaction required of the Company in connection with such registration
or qualification under such state securities or blue sky laws and the Company
shall reimburse on demand each Indemnified Person for any legal or any other
costs and expenses reasonably incurred by any of them in connection with
investigating, preparing for, defending or settling any such loss, claim,
damage, liability or action by any governmental agency or body; provided,
however, that the Company shall not be liable in any such case to the extent
that any such loss, claim, damage, liability or expense arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in said registration statement, preliminary or final
prospectus or amendment or supplement thereto or any document incident to
registration or qualification of any Restricted Shares pursuant to Section
2.4(d) hereof, in reliance upon and in conformity with written information
furnished to the Company by any Participating Shareholder, underwriter, broker,
other person or controlling person specifically for use in the preparation
thereof or arises out of or is based upon the Indemnified Person's failure to
deliver a copy of the registration statement or prospectus or any amendments or
supplements thereto after the Company has furnished such Indemnified Person with
a sufficient number of copies of the same; provided further, that the Company
shall not be liable for any settlement made without its prior written consent,
such consent not to be unreasonably withheld.

                  (b) Before Restricted Shares shall be included in any
registration pursuant to this Article 2, each Participating Shareholder will
furnish to the Company in writing such information and affidavits as the Company
reasonably requests for use in connection with any registration statement and
prospectus, and each such Participating Shareholder and any underwriter acting
on its behalf shall have agreed to indemnify and hold harmless (in the same
manner and to the same extent as set forth in paragraph (a) above) the Company,
each director of the Company, each officer of the Company who signs such
registration statement, every other Participating Shareholder and any person who
controls the Company within the meaning of the Securities Act, with respect to
any untrue statement or omission from such registration statement, any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereto, if such untrue statement or omission was made in reliance
upon and in conformity with written information furnished to the Company by the
Participating Shareholder or such underwriter specifically for use in the
preparation of such registration statement, preliminary prospectus, final
prospectus or amendment or supplement; provided, however, that



                                       11
<PAGE>

the maximum amount of liability in respect of such indemnification shall be
limited to an amount equal to the net proceeds actually received by such
Participating Shareholder from the sale of Restricted Shares effected pursuant
to such registration.

                  (c) Promptly after receipt by an indemnified party of notice
of the commencement of any action involving a claim referred to in Section
2.9(a) or (b) hereof, such indemnified party will, if a claim in respect thereof
is to be made against the indemnifying party under this Section 2.9, give prompt
written notice to the latter of the commencement of such action (provided that
the failure to give such notice shall not limit the rights of such indemnified
party unless and to the extent such failure is prejudicial to its ability to
defend such action). In case any such action is brought against an indemnified
party, the indemnifying party will be entitled to participate in and to assume
the defense thereof, jointly with any other indemnifying party similarly
notified to the extent that it may wish, with counsel reasonably satisfactory to
such indemnified party, and, after notice to such indemnified party from the
indemnifying party of its election to assume the defense thereof; provided,
however, that, if any indemnified party shall have reasonably concluded that
there may be one or more legal defenses available to such indemnified party
which are different from, in conflict with or additional to those available to
the indemnifying party, or that such claim or litigation involves or could
reasonably be expected to have an effect upon matters beyond the scope of the
indemnity agreement provided in this Section 2.9, or if the indemnifying party
fails to take diligent action to defend such claim within twenty (20) days
following notice thereof from the indemnified party, the indemnifying party
shall not have the right to assume the defense of such action on behalf of such
indemnified party, or that such claim or litigation involves or could have an
effect upon matters beyond the scope of the indemnity agreement provided in this
Section 2.9, or if the indemnifying party fails to take diligent action to
defend such claim within twenty (20) days following notice thereof from the
indemnified party, and such indemnifying party shall reimburse such indemnified
party and any person controlling such indemnified party for the fees and
expenses of counsel retained by the indemnified party which are reasonably
related to the matters covered by the indemnity agreement provided in this
Section 2.9. If the indemnifying party does assume its own defense, from such
time the indemnified party shall bear the expenses of its own separate counsel.
If such defense is not assumed by the indemnifying party as permitted hereunder,
the indemnifying party will not be subject to any liability for any settlement
made by the indemnified party without its written consent, which consent shall
not be unreasonably withheld. If such defense is assumed by the indemnifying
party pursuant to the provisions hereof, such indemnifying party shall not make
any settlement of the applicable claim indemnified against hereunder without the
written consent of the indemnified party or parties, which consent shall not be
unreasonably withheld. An indemnifying party that is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party and any other such indemnified party with respect to such
claim, unless in the reasonable judgment of any indemnified party, a conflict of
interest may exist between such indemnified party with respect to such claim, in
which event the indemnifying party shall be obligated to pay the reasonable fees
and disbursements of such additional counsel or counsels.

                  (d) In order to provide for just and equitable contribution to
joint liability under the Securities Act in any case in which an Indemnified
Person makes a claim for indemnification pursuant to this Section 2.9, but it is
judicially determined (by the entry of a final



                                       12
<PAGE>

judgment or decree by a court of competent jurisdiction and the expiration of
time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced notwithstanding the fact that this Section
2.9 provides for indemnification in such case, then the Company and the
Participating Shareholder will contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject as is appropriate to
reflect, as between the indemnifying party, on the one hand, and the indemnified
party on the other hand, the relative fault of the indemnifying party, on the
one hand, and the indemnified party, on the other hand, in connection with the
statements or omissions which resulted in such losses, claims, damages or
liabilities, it being understood that the parties acknowledge that the
overriding equitable consideration to be given effect in connection with this
provision is the ability of one party or the other to correct the statement or
omission which resulted in such losses, claims, damages or liabilities, and that
it would not be just and equitable if contribution pursuant hereto were to be
determined by pro rata allocation or by any other method of allocation which
does not take into consideration the foregoing equitable considerations.
Notwithstanding the foregoing, (i) the Participating Shareholder will not be
required to contribute any amount in excess of the proceeds to it of all
Restricted Shares sold by it pursuant to such registration statement, (ii) no
underwriter shall be required to contribute any amount in excess of the proceeds
to it from the offering pursuant to such registration statement, and (iii) no
person or entity guilty of fraudulent misrepresentation, within the meaning of
Section 11(f) of the Securities Act, shall be entitled to contribution from any
person or entity who is not guilty of such fraudulent misrepresentation. If
indemnification is available under this Section 2.9, the indemnifying parties
shall indemnify each indemnified party to the full extent provided in Section
2.9(a) and 2.9(b) without regard to the relative fault of said indemnifying
party or indemnified party or any other equitable consideration provided for in
this Section 2.9(d).

                  (e) Notwithstanding any of the foregoing, if in connection
with an underwritten public offering of any Restricted Shares, the Company, the
Participating Shareholder and the underwriters enter into an underwriting or
purchase agreement relating to such offering which contains provisions covering
indemnification among the parties, the indemnification provided thereunder shall
be in addition to (and not in lieu of) the indemnification provided to the
Shareholders hereunder.

                  (f) The indemnification and contribution required by this
Section 2.9 shall be made by periodic payment of the amount thereof during the
course of the investigation or defense, as and when bills are received or
expense, loss, damage or liability is incurred; provided, that if a court of
competent jurisdiction finally determines that any Indemnified Person which has
received payments hereunder does not have an indemnification right under Section
2.9 for any reason, then such Indemnified Person shall within five (5) days of
such final determination, refund all amounts received hereunder to the Company.

                  (g) The indemnification and contribution provided for
hereunder will remain in full force and effect regardless of any investigation
made by or on behalf of any Indemnified Person and will survive the transfer of
securities.

                  ARTICLE 3. MISCELLANEOUS



                                       13
<PAGE>

                  3.1 NOTICES. Any and all notices, designations, consents,
offers, acceptances, or any other communication required or permitted to be
given by any provision of this Agreement shall be deemed to be sufficient if
contained in a written instrument delivered in person or duly sent by registered
mail or telecopied with acknowledgment of receipt sent by telecopier, registered
mail or delivered in person, as the case may be, to such party at the address or
telecopier number, as the case may be, set forth on the signature pages hereto
or to such other address or telecopier number, as the case may be, as such party
may from time to time designate in writing to the other parties. All such
notices, requests, consents and other communications shall be deemed to have
been received: (a) in the case of personal delivery or registered mail, on the
date of receipt; or (b) in the case of telecopying, on the date of
acknowledgment thereof.

                  3.2 AMENDMENT AND WAIVER. No change or modification of, or
waiver of compliance with, this Agreement shall be valid unless the same shall
be in writing and signed by all of the parties hereto which hold at least 50,000
shares of the Stock, on an as-converted basis.

                  3.3 TERMINATION. This Agreement may be terminated at any time
by an instrument in writing signed by all of the parties hereto. This Agreement
shall terminate automatically as to any Shareholder which transfers all of its
Restricted Shares. Unless sooner terminated, this Agreement shall terminate
eight (8) years from the date hereof, unless, at any time within one (1) year
prior to such date, all of the parties extend its duration for as many
additional periods, each not to exceed eight (8) years, as they may desire.

                  3.4 NO WAIVER. No failure or delay on the part of the
Shareholders or any of them in exercising any right, between the Company and the
Shareholders or any of them shall operate as a waiver thereof nor shall any
single or partial exercise of any right, power or privilege hereunder preclude
the simultaneous or later exercise of any other right, power or privilege. The
rights and remedies herein expressly provided are cumulative and not exclusive
of any rights or remedies which the Shareholders or any of them would otherwise
have. No notice to or demand on the Company in any case shall entitle the
Company to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Shareholders or any of
them to take any other or further action in any circumstances without notice or
demand.

                  3.5 SPECIFIC PERFORMANCE. Each party to this Agreement
acknowledges that the other parties will suffer irreparable injury in the event
of any breach of any provision of this Agreement and that therefore the remedy
at law for any breach or threatened breach of any such provision of this
Agreement will be inadequate. Accordingly, upon a breach or threatened breach of
any such provision of this Agreement by any party hereto, the other parties
shall, in addition and without prejudice to any of the rights and remedies they
may have, be entitled as a matter of right, without proof of actual damages, to
seek specific performance of such provisions of this Agreement and to such other
injunctive or equitable relief to enforce, or prevent any violations (whether
anticipatory, continuing or future) of, such provisions of this Agreement.

                  3.6 COUNTERPARTS AND HEADINGS. This Agreement may be executed
in two or more counterparts, each of which shall be deemed to be an original,
but all of which together shall constitute one and the same instrument. All
headings and any cover page or table of



                                       14
<PAGE>

contents are inserted for convenience or reference only and shall not affect its
meaning or interpretation.

                  3.7 NOUNS AND PRONOUNS. Whenever the context may require, any
pronouns used herein shall include the corresponding masculine, feminine or
neuter forms, and the singular form of nouns and pronouns shall include the
plural and vice-versa.

                  3.8 EXPENSES. Except as provided in Section 2.8 hereto, each
of the parties to this Agreement shall bear its own expenses, including, without
limitation, the fees and disbursements of its respective counsel, in connection
with the negotiation and execution of this Agreement and the consummation of the
transactions contemplated hereby.

                  3.9 GOVERNING LAW. This Agreement will be governed by, and
construed and enforced in accordance with, the laws of the State of New York,
U.S.A., without regard to its conflict of law rules.

                  3.10 SUBMISSION TO JURISDICTION; CONSENT TO SERVICE OF
PROCESS.

                  (a) The parties hereto hereby irrevocably submit to the
non-exclusive jurisdiction of any federal or state court located within the
Borough of Manhattan, State of New York over any dispute arising out of or
relating to this Agreement or any of the transactions contemplated hereby and
each party hereby irrevocably agrees that all claims in respect of such dispute
or any suit, action or proceeding related thereto may be heard and determined in
such courts. The parties hereby irrevocably waive, to the fullest extent
permitted by applicable law, any objection which they may now or hereafter have
to the laying of venue of any such dispute brought in such court or any defense
of inconvenient forum for the maintenance of such dispute. Each of the parties
hereto agrees that a judgment in any such dispute may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

                  (b) Each of the parties hereto hereby consents to process
being served by any party to this Agreement in any suit, action or proceeding by
the mailing of a copy thereof in accordance with the provisions of Section 3.1
hereof.

                  3.11 SUCCESSORS AND ASSIGNS. This Agreement shall be binding
upon and shall inure to the benefit of the Company and its successors, and each
of the Shareholders and their respective executors, administrators and personal
representatives and heirs and their successors and assigns.

                  3.12 SEVERABILITY. In the event that any provision of this
Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, invalid or unenforceable, the remaining provisions hereof shall
nevertheless continue in full force and effect as though the illegal, invalid or
unenforceable provisions were not a part hereof, and the parties shall exert
their best efforts to amend this Agreement to include a provision which is
legal, valid and enforceable and which carries out the original intent of the
parties.

                  3.13 COMPLETE AGREEMENT. This Agreement contains the entire
agreement among the parties with respect to the subject matter hereof and
supersedes all prior and



                                       15
<PAGE>

contemporaneous arrangements or understandings, whether written or oral, between
or among any of the parties hereto, with respect to the subject matter hereof.

                  3.14 FURTHER ASSURANCES. Each of the parties to this Agreement
agrees to execute such other documents and take such other action as may be
reasonably necessary to implement and carry out the intent of this agreement.

                  3.15 CONFIDENTIALITY. Each Shareholder (other than Intel
Atlantic, Inc.) covenants and agrees to treat any non-public information
provided to it by the Company concerning the business and finances of the
Company ("Corporate Information") as confidential and agrees further that it
will not use, exploit, reproduce, disclose or provide Corporate Information to
any third party (other than any agents of the Shareholder who are bound by
substantially similar obligations of confidentiality) on its own behalf or
otherwise, except with the consent of the Company or as required by law, legal
process or any federal or state regulatory body having jurisdiction over such
Shareholder. The provisions of this Section 3.15 shall not apply to any
information which:

                  (a) was within the public domain prior to the time of
disclosure of Corporate Information to the Shareholder or which comes into the
public domain other than as a result of a breach by the Shareholder of this
Section 3.15;

                  (b) was in the possession of the Shareholder (or any of its
officers, directors, employees, agents, principals, or affiliates) before the
Shareholder received the Corporate Information;

                  (c) was rightfully acquired by the Shareholder from a third
party without, to the knowledge of the Shareholder, any restriction or any
obligation of confidentiality; or

                  (d) was independently developed by the Shareholder without any
use or reference to the Corporate Information.

                  The provisions of this Section 3.15 shall survive the
termination of this Agreement, either in whole or as to any Shareholder, for a
period of two (2) years.

                  The obligations of Intel Atlantic, Inc., with respect to the
treatment of Corporate Information are set forth in Exhibit A hereto.

Intel Corporation
2200 Mission College Blvd.
Santa Clara, CA  95052


         In consideration of the purchase by Intel Atlantic, Inc. ("Intel") of
555,555.55 shares of Class B Preferred Stock of El Sitio, Inc. ("Company"),
pursuant to a Share Purchase Agreement dated November 9, 1999 (the "Purchase
Agreement"), Company and Intel agree to the terms and obligations of this letter
agreement ("Agreement").

1.       CONFIDENTIALITY

         (a) DISCLOSURE OF TERMS. The terms and conditions of this Agreement,
the Purchase Agreement, the Amended and Restated Shareholders Agreement, dated
November 9, 1999 and the Amended and Restated Registration Rights Agreement,
dated November 9, 1999 (collectively, the "Financing Terms"), including their
existence, shall be considered confidential information and shall not be
disclosed by the Company to any third party except in accordance with the
provisions set forth below.

         (b) PRESS RELEASES, ETC. Within sixty (60) days after the closing of
the transactions contemplated by the Purchase Agreement, the Company may issue a
press release disclosing that the Investors, including Intel, have invested in
the Company; provided that the release does not disclose any of the Financing
Terms and the final form of the press release is approved in advance in writing
by the Intel. Intel's name and the fact that Intel is an investor in the Company
can be included in a reusable press release boilerplate statement, so long as
Intel has given the Company its initial approval of such boilerplate statement
and the boilerplate statement is reproduced in exactly the form in which it was
approved. No other announcements regarding Intel in a press release, conference,
advertisement, announcement, professional or trade publication, mass marketing
materials or otherwise to the general public may be made without Intel's prior
written consent.

         (c) PERMITTED DISCLOSURES. Notwithstanding the foregoing, (i) the
Company may disclose any of the Financing Terms to its current or bona fide
prospective investors, employees, investment bankers, lenders, accountants and
attorneys, in each case only where such persons or entities are under
appropriate nondisclosure obligations; (ii) the Company may disclose (other than
in a press release or other public announcement described in subsection (b))
solely the fact that Intel is an investor in the Company to any third parties
without the requirement for the consent of any other party or nondisclosure
obligations; and (iii) Intel may disclose its investment in the Company and the
Financing Terms to third parties or to the public at its sole


<PAGE>

discretion and, if it does so, the Company shall have the right to disclose to
third parties any such information disclosed in a press release or other public
announcement by Intel.

         (d) LEGALLY COMPELLED DISCLOSURE. In the event that any party is
requested or becomes legally compelled (including without limitation, pursuant
to securities laws and regulations) to disclose the existence of the agreements
referenced in paragraph (a) above or any of the Financing Terms hereof in
contravention of the provisions of this letter, the Company shall provide Intel
with prompt written notice of that fact so that the appropriate party may seek
(with the cooperation and reasonable efforts of the other) a protective order,
confidential treatment or other appropriate remedy. In such event, the Company
shall furnish only that portion of the information which is legally required and
shall exercise reasonable efforts to obtain reliable assurance that confidential
treatment will be accorded such information to the extent reasonably requested
by Intel.

         (e) OTHER INFORMATION. The provisions of this Letter Agreement shall be
in addition to, and not in substitution for, the provisions of any separate
nondisclosure agreement executed by any of the parties hereto with respect to
the transactions contemplated hereby. Additional disclosures and exchange of
confidential information between the Company and Intel Corporation shall be
governed by the terms of the Corporate Non-Disclosure Agreement No. 7626010,
dated October 18, 1999, executed by the Company and Intel, and any Confidential
Information Transmittal Records (CITR) provided in connection therewith.

         (f) All notices required under this section shall be made pursuant to
Section 9.10 of the Purchase Agreement.

2.       MISCELLANEOUS.

         2.1 DEFINITIONS. All capitalized terms used but not otherwise defined
in this Agreement have the meaning defined for such terms in the Purchase
Agreement.

         2.2 GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

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

         2.4 AMENDMENTS AND WAIVERS. This Agreement may not be amended or
modified without the written consent of Intel and the Company, nor shall any
waiver be effective against any party unless in a writing executed on behalf of
such party.

         2.5 SEVERABILITY. If any provision of this Agreement shall be declared
void or unenforceable by any judicial or administrative authority, the validity
of any other provision and of the entire Agreement shall not be affected
thereby.

employment related buy-back is carried out in accordance with a severance
arrangement;

                        (iv)    insolvency, protection measures against

ARTICLE 3.         TRANSFERS OF SHARES; PREEMPTIVE RIGHTS

                  3.1.  RESTRICTION ON TRANSFER. The El Sitio Shares held by any
Shareholder and comprising its Interest ("Covered Shares") shall not be
transferable, directly or indirectly, except upon the conditions specified in
this Article 3, which conditions are intended, in part, to ensure compliance
with the provisions of the Securities Act in respect of any disposition of any
Covered Shares or any interest therein which would constitute a sale thereof
within the meaning of the Securities Act (a "Transfer"). As used in this Article
3, the term "Transferor" refers to the transferor (whether by voluntary or
involuntary means) of any Covered Shares, the term "Other Shareholder" means the
Shareholder which is not the Transferor, and the term "Subject Shares" means the
shares of Covered Shares that have been or are to be Transferred.

                  3.2.  INVOLUNTARY TRANSFERS. In the event that an Involuntary
Transfer (as hereinafter defined) by any Shareholder of any Covered Shares may
occur, the following procedures shall apply:

                  (a)   The Shareholder to be deprived or divested of Covered
Shares by the Involuntary Transfer shall promptly give written notice of such
Involuntary Transfer in reasonable detail to the Company and to the Other
Shareholders, and the person or persons who take or propose to take any interest
in the Subject Shares as a result of such Involuntary Transfer (the
"Transferee") shall hold such interest subject to the rights of the Other
Shareholder as set forth below.

                  (b)   Upon receipt of the notice referred to in Section 3.2(a)
above or upon discovery of such Involuntary Transfer, the Company shall cause
the appraisal referred to in Section 3.2(c) to be made and each of the Other
Shareholders shall have the irrevocable option, but not the obligation, for a
period of sixty (60) days following receipt by all Other Shareholders of the
results of such appraisal, to purchase the Subject Shares, subject to the terms
set forth herein. Each Other Shareholder may exercise the option for the number
of Subject Shares which bears the same relation to the total number of Subject
Shares as (x) such Other Shareholder's Interest bears to (y) the aggregate
Interest then held by all of the Other Shareholders exercising such option (and
purchasing Subject Shares under Section 3.2(c) below), or for such other number
of Subject Shares as all of the Other Shareholders exercising such option may
agree in writing. In the event that the Other Shareholders elect to purchase, in
the aggregate, less than all of the Subject Shares, then the Other Shareholders
shall have no right to purchase any of the Subject Shares.

                  (c)   The closing for any such sale of Subject Shares to one
or more Other Shareholders shall be at the offices of the Company on a mutually
satisfactory business day within fifteen (15) days after the expiration of such
sixty (60) day period. The purchase price per share of any Subject Shares
purchased pursuant to this Section 3.2 shall be the amount which is equal to the
fair value, as of the Valuation Date (as hereinafter defined), of a Subject
Share, as such fair value is determined by an independent appraiser selected by
the Company and reasonably acceptable to the Shareholders holding, in the
aggregate, the majority of the aggregate Interests, and all costs of any such
appraisal shall be paid by the Company. The "Valuation


                                       10
<PAGE>

Date" shall be the last day of the calendar quarter immediately preceding the
Involuntary Transfer.

                  (d)   For purposes of this Agreement, the term "Involuntary
Transfer" shall mean any involuntary sale, transfer, encumbrance or other
disposition by or in which any Shareholder shall be deprived or divested of any
right, title or interest in or to any Covered Shares, including, without
limitation, any levy of execution, transfer in connection with bankruptcy,
judicial reorganization, insolvency or similar proceedings or any transfer to a
public officer or agency pursuant to any abandoned property or escheat law;
provided that any Transfer complying with Section 3.3, Section 3.4, Section 3.5
or Section 3.6 hereof shall not be deemed to be an "Involuntary Transfer."

                  3.3.  RIGHTS OF FIRST OFFER. Except as otherwise expressly
provided in Sections 3.4 and 3.5 hereof, each Shareholder (other than any Class
B Shareholder) hereby agrees that it shall not effect a Transfer of any Covered
Shares and to the extent that any offers made pursuant to this Section 3.3(a)
will not violate the Securities Act, except in accordance with the following
procedures:

                  (a)   In the event that a Shareholder (other than a Class B
Shareholder) wishes to make a Transfer of any Covered Shares, the Transferor
shall first deliver to the Other Shareholders a written notice (the "Offer
Notice"), which Offer Notice shall (i) specify the terms, including the number
of shares of Covered Shares to be sold, and the price per share at which the
Transferor proposes to Transfer such Covered Shares, and (ii) be irrevocable for
a period of fifteen (15) days after delivery thereof, offering (the "Offer") to
the Other Shareholders all of the Subject Shares proposed to be sold by the
Transferor at the purchase price and on the terms specified therein. Each of the
Other Shareholders shall have the right and option, at its sole discretion, for
a period of fifteen (15) days after delivery of the Offer Notice (the
"Acceptance Period"), to accept all, but not less than all, of the Subject
Shares (pro rata among such Other Shareholders so electing on the basis of the
number of El Sitio Shares owned by such Other Shareholders) offered at a price
equal to the purchase price and upon the other terms stated in the Offer Notice.
Such acceptance may be made by delivery of a written notice to the Transferor
within said fifteen (15) day period, which notice shall specify whether such
Shareholder wishes to purchase more than its pro rata share, if Other
Shareholders decline to purchase, and if so, the maximum purchase such
Shareholder elects to make. In the event that any Shareholder elects not to
exercise its pro rata right to purchase, the Other Shareholder(s) shall have the
right to purchase the Subject Shares otherwise allocable to the
non-participating Shareholder pro rata to their participation in the Offer,
subject to the limits set forth in the applicable Offer Notice. In the event
that the Other Shareholders elect not to purchase all of the Subject Shares,
then the Other Shareholders shall have no right to purchase all or any portion
of such Subject Shares and the Transferor shall be free to Transfer the Subject
Shares in accordance with Section 3.3(c). A Shareholder electing to purchase
Subject Shares pursuant to this Section 3.3 is referred to herein as a
"Purchasing Shareholder"). For purposes of this Section 3.3, if the Transferor
is transferring the Company's common shares, then the Class B Shareholders shall
be included as Other Shareholders; in all other cases, the Class B Shareholders
shall not be included as Other Shareholders


                                       11
<PAGE>


                  (b)   Notwithstanding anything to the contrary contained in
Section 3.3 hereof, in the event the Transferor is one of the (i) Initial
Shareholders, the other Initial Shareholders will have a priority right of first
offer with respect to any Subject Shares offered by an Initial Shareholder, in
accordance with the terms and conditions of the Syndication Agreement among the
Initial Shareholders and dated as of June 10, 1999, before any such right may be
exercised by the Shareholders of any other class or (ii) Class A Shareholders,
the other Class A Shareholders will have a priority right of first offer with
respect to any Class A Preferred Shares offered by a Class A Shareholder, before
any such right may be exercised by the Other Shareholders.

                  (c)   Transfers, if any, of Subject Shares to the Purchasing
Shareholder under the terms of this Section 3.3 shall be made at the offices of
the Company or any other address acceptable to the Company on a mutually
satisfactory business day within fifteen (15) days after the expiration of the
Acceptance Period. The Transferor shall deliver the Subject Shares by delivering
share certificates representing such Subject Shares, duly endorsed for transfer,
against payment of the purchase price thereof, in accordance with the terms of
the Offer.

                  (d)   If effective acceptance shall not be received pursuant
to Section 3.3(a) above, with respect to all Covered Shares offered for sale
pursuant to the Offer Notice, then the Transferor may Transfer all or any part
of the El Sitio Shares so offered for sale at a price not less than the price,
and on terms not more advantageous to the purchaser than the terms stated in the
Offer Notice at any time within one hundred eighty (180) days after the
expiration of the Acceptance Period.

                  (e)   In the event that any Shareholder exercises a purchase
right under Section 3.3(a) and then fails to consummate such purchase in
accordance with the terms of the Offer Notice (each such Shareholder, a
"Defaulting Shareholder"), then, in addition to any remedies at law or in equity
that the Transferor may have in respect of such failure, the Defaulting
Shareholder shall thereafter cease to have any right to receive offers or
purchase shares pursuant to Section 3.3(a).

                  3.4.  EXEMPT TRANSFERS. Anything contained herein to the
contrary notwithstanding, the provisions of Sections 3.3, 3.5 and 3.6 shall not
be applicable to a Transfer (i) to an Affiliate of a Shareholder or for the
benefit of an Affiliate or family member of a Shareholder, if made solely for
personal tax or estate planning purposes of the Transferor, or (ii) in an
offering pursuant to the exercise of registration rights under the Registration
Rights Agreement, provided such Affiliate executes all documents (including the
representation that such Transfer may be effected without registration under the
applicable provisions of the Securities Act and state securities or blue sky
laws) deemed reasonably necessary by the Other Shareholder to cause the
Affiliate to become a party to, and be bound by, the terms of this Agreement.

                  3.5.  TAG-ALONG RIGHTS.

                  (a)   RIGHT TO PARTICIPATE IN SALE. Notwithstanding any other
provision hereof, if any Shareholder party hereto, other than any Class B
Shareholder (such Shareholders, together with their Affiliates, the "Selling
Shareholder(s)") proposes to enter into an agreement with a


                                       12
<PAGE>


third party to sell or otherwise dispose of for value (such sale or other
disposition for value being referred to as a "Tag-Along Sale") El Sitio Shares
held by it to a third party who is not an Affiliate (any such party, a "Third
Party") pursuant to a bona fide transaction (or series of related transactions)
in which securities representing an aggregate Interest of fifty percent (50%) or
more will be sold to a Third Party, then the Selling Shareholder(s) shall afford
the Other Shareholder(s), (the "Tag-Along Shareholders") the opportunity to
require that the sale by the Selling Shareholder(s) be conditioned upon such
Third Party purchasing that number of El Sitio Shares owned by such Tag-Along
Shareholder which delivers a Tag-Along Notice in accordance with Section 3.5(c)
equal to the product (rounded up to the nearest whole number) of (i) the
quotient determined by dividing (A) the number of El Sitio Shares owned by such
Tag-Along Shareholder, by (B) the number of El Sitio Shares owned by the Selling
Shareholders and all Tag-Along Shareholders which are selling El Sitio Shares in
the contemplated Tag-Along Sale, and (ii) the number of El Sitio Shares proposed
to be sold by all Shareholders in the contemplated Tag-Along Sale. In
negotiating a Tag-Along Sale, the Selling Shareholder(s) shall provide (i) that
the only representations, warranties or covenants which any Tag-Along
Shareholder shall be required to make in connection with any Transfer are
representations and warranties with respect to its own ownership of the shares
to be sold by it and its ability to convey title thereto free and clear of
liens, encumbrances or adverse claims, its due organization, its due
authorization, execution and delivery of the definitive purchase agreement (if
applicable), enforceability of such purchase agreement against it and no
conflict of it with such purchase agreement, and (ii) that the liability of the
Tag-Along Shareholder with respect to any representation and warranty made in
connection with any Transfer is the several liability of such Tag-Along
Shareholder (and not joint with any other person) and that such liability is
limited to the amount of proceeds actually received by such Tag-Along
Shareholder; provided, however, that the foregoing shall not limit the
obligations of such Tag-Along Shareholder, and such Tag-Along Shareholder hereby
expressly agrees to be bound by and be subject to, any escrow or other holdback
arrangement (on a pro rata basis based on the number of shares sold by such
Tag-Along Shareholder in proportion to all shares of the Company sold in such
Tag-Along Sale) provided for in the agreement relating to the Tag-Along Sale.
For purposes of this Section 3.5, if the Selling Shareholder is transferring the
Company's common shares, then the Class B Shareholders shall be included as
Tag-Along Shareholders; in all other cases, the Class B Shareholders shall not
be included as Other Shareholders.

                  (b)   SALE NOTICE. The Selling Shareholder(s) shall provide
each Tag-Along Shareholder and the Company with written notice (the "Tag-Along
Sale Notice") not less than thirty (30) days prior to the proposed date of the
Tag-Along Sale (the "Tag-Along Sale Date"). Each Tag-Along Sale Notice shall be
accompanied by a copy of any agreement relating to the Tag-Along Sale (if
available) and shall set forth: (i) the name and address of the Third Party in
the Tag-Along Sale; (ii) the number of shares proposed to be Transferred by the
Selling Shareholder(s); (iii) the proposed amount and form of consideration to
be paid for such shares expressed on a per share basis and the terms and
conditions of payment offered by the Third Party; (iv) the aggregate number of
shares of the Company held of record by the Selling Shareholder(s) as of the
close of business on the day immediately preceding the date of the Tag-Along
Notice (the "Tag-Along Notice Date"); (v) confirmation that the Third Party has
been informed of the "Tag-Along Rights" provided for herein and has agreed to
purchase shares from


                                       13
<PAGE>

any Tag-Along Shareholder in accordance with the terms hereof; and (vi) the
Tag-Along Sale Date.

                  (c)   TAG-ALONG NOTICE. Any Tag-Along Shareholder wishing to
participate in the Tag-Along Sale shall provide written notice (the "Tag-Along
Notice") to the Selling Shareholder(s) no less than fifteen (15) days prior to
the Tag-Along Sale Date. The Tag-Along Notice shall set forth the number of El
Sitio Shares that such Tag-Along Shareholder elects to include in the Tag-Along
Sale. The Tag-Along Notice given by any Tag-Along Shareholder shall constitute
such Tag-Along Shareholder's binding agreement to sell the shares specified in
the Tag-Along Notice on the terms and conditions applicable to the Tag-Along
Sale; provided, however, that in the event that there is any material change in
the material terms and conditions of such Tag-Along Sale applicable to the
Tag-Along Shareholder (including, but not limited to, any decrease in the
purchase price that occurs other than pursuant to an adjustment mechanism set
forth in the agreement relating to the Tag-Along Sale) after such Tag-Along
Shareholder gives its Tag-Along Notice, then, notwithstanding anything herein to
the contrary, the Tag-Along Shareholder shall have the right to withdraw from
participation in the Tag-Along Sale with respect to all of its El Sitio Shares
affected thereby. If the Third Party does not consummate the purchase of all the
El Sitio Shares requested to be included in the Tag-Along Sale by any Tag-Along
Shareholder on terms and conditions which are no more favorable in any material
respect to the Selling Shareholder (except as otherwise provided herein), then
the Selling Shareholder(s) shall not consummate the Tag-Along Sale of any of its
shares to the Third Party. If a Tag-Along Notice from any Tag-Along Shareholder
is not received by the Selling Shareholder(s) prior to the fifteen (15) day
period specified above, the Selling Shareholder(s) shall have the right to
consummate the Tag-Along Sale without the participation of such Tag-Along
Shareholder, but only on terms and conditions which are no more favorable in any
material respect to the Selling Shareholder (and in any event, at no greater a
purchase price, except as the purchase price may be adjusted pursuant to the
agreement regarding the relevant sale or other disposition) than as stated in
the Tag-Along Sale Notice and only if such Tag-Along Sale occurs on a date
within one hundred eighty (180) days of the Tag-Along Sale Date. If such
Tag-Along Sale does not occur within such one hundred eighty (180) day period,
the El Sitio Shares that were to be subject to such Tag-Along Sale thereafter
shall continue to be subject to all of the restrictions contained in this
Agreement.

                  (d)   DELIVERY OF SHARES. On the Tag-Along Sale Date, each
Tag-Along Shareholder shall deliver the shares to be sold in connection with the
Tag-Along Sale to the Third Party by delivering share certificates representing
such shares, duly endorsed for transfer, against delivery of immediately
available funds in the amount of the purchase price for such shares.

                  (e)   NO WAIVER. Any election in any instance by a Shareholder
not to exercise its rights to participate in a Tag-Along Sale under this Section
3.5 shall not constitute a waiver of such rights with respect to any other
proposed Transfer of shares of the Company which would trigger such rights.

                  3.6.  DRAG-ALONG RIGHTS.

                  (a)   GRANT OF DRAG-ALONG RIGHTS. If any Shareholder(s) party
hereto, other than any Class B Shareholder (such Shareholders, together with
their Affiliates, the "Selling Shareholder(s)") proposes to enter into an
agreement with a Third Party to sell or otherwise dispose of for value (such
sale or other disposition for value being referred to as a "Drag-Along Sale") El
Sitio Shares held by it to a Third Party pursuant to a bona fide transaction (or
series of related transactions) in which securities representing an aggregate
Interest of fifty percent (50%) or more will be sold to a Third Party, then the
remaining Shareholder(s), other than the Class B Shareholders (the "Drag-Along
Shareholder") shall, upon the written request of the Selling Shareholder(s),
sell to such Third Party (i) El Sitio Shares owned by such Drag-Along
Shareholder equal to (A) the number of El Sitio Shares owned by such Drag-Along
Shareholder multiplied by (B) a fraction ("Drag-Along Fraction"), the numerator
of which is the number of El Sitio Shares the Selling Shareholder(s) intend to
sell pursuant to this Section 3.6 and the denominator of which is the aggregate
number of El Sitio Shares owned by the Selling Shareholder(s), and (ii) warrants
owned by such Drag-Along Shareholder representing the right to acquire a number
of shares equal to (A) the number of shares underlying such Drag-Along
Shareholders warrants multiplied by (B) the Drag-Along Fraction,
contemporaneously with the sale of such El Sitio Shares by the Selling
Shareholder(s), for, with respect to the El Sitio Shares, the same consideration
and on the same terms as those provided by such Third Party to the Selling
Shareholder(s) and, with respect to the warrants, for the same consideration and
on the same terms as those provided by such Third Party to the Selling
Shareholder(s) less the aggregate exercise price for the warrants so
transferred.

                  (b)   EXERCISE OF DRAG-ALONG RIGHT. The Drag-Along Right shall
be exercisable by written notice given by the Selling Shareholder(s) to each
Drag-Along Shareholder containing the price and other material terms of the
proposed sale and the date of the closing of the proposed sale (the "Drag-Along
Sale Date"), which date shall not be less than twenty (20) nor more than sixty
(60) calendar days after the date of such notice.

                  (c)   DELIVERY OF SHARES. On the Drag-Along Sale Date, each
Drag-Along Shareholder shall deliver the shares to be sold in connection with
the Drag-Along Sale to the Third Party by delivering share certificates
representing such shares, duly endorsed for transfer, against delivery of
immediately available funds in the amount of the purchase price for such shares.

                  3.7.  TRANSFERS IN VIOLATION OF AGREEMENT. If any voluntary
Transfer of El Sitio Shares is made or attempted contrary to the provisions of
this Agreement (such Transfer, an "Unauthorized Transfer"), the Other
Shareholders shall have the right to purchase all or part of such El Sitio
Shares from the owner thereof or the owner's transferee at any time before or
after the Transfer at a purchase price per share equal to (i) if any El Sitio
Shares are listed for trading on NASDAQ or the Bolsa de Comercios de Buenos
Aires, the lesser of (x) eighty percent (80%) of the thirty (30) day average
closing price over the thirty-day period immediately preceding the date of the
initial Transfer contrary to this Agreement, or (y) eighty percent (80%) of the
thirty (30) day average closing price for the thirty days immediately preceding
the date of exercise of


                                       15
<PAGE>


the right granted to the Other Shareholders herein, or (ii) if no El Sitio
Shares are listed for trading on NASDAQ or the Bolsa de Comercios de Buenos
Aires, the lesser of (x) eighty percent (80%) of the Fair Value at the time of
the initial transfer that was contrary to this Agreement, or (y) eighty percent
(80%) of the Fair Value at the time of the Other Shareholders' purchase of such
El Sitio Shares. The term "Fair Value" shall mean the amount at which the El
Sitio Shares would change hands between an independent, willing buyer and an
independent, willing seller, each having reasonable knowledge of all relevant
facts and neither being under any compulsion to act (considering, where
applicable, the relative rights of all outstanding classes or series of capital
stock but not discounting the value of such securities for illiquidity or
because they represent a minority ownership position in the Company), which
amount shall be determined by the Board in its reasonable discretion and in good
faith.

                  3.8.  PREEMPTIVE RIGHTS.

                  (a)   Except for the issuance of the Company's capital stock
or other securities (i) pursuant to a Qualifying IPO (as defined in the
Memorandum), (ii) comprising additional shares or option issuances to Employees
of the Company pursuant to share option plans existing on the date hereof
including the number of shares issuable thereunder as of the date hereof (or
amendments to such plans or new plans if agreed to by the Shareholders), (iii)
comprising Class B Preferred Shares, up to an aggregate of 1,888,889 Class B
Preferred Shares, or (iv) in connection with acquisitions of businesses by the
Company approved by the Shareholders, if the Company at any time after the date
hereof authorizes the issuance or sale of any capital stock of the Company or
any securities of the Company containing options or rights to acquire any shares
of capital stock (other than as a dividend on the outstanding capital stock),
the Company shall first offer to sell to the Shareholders on a pro rata basis,
all of such capital stock or other securities (the "Offered Shares").

                  (b)   In order to exercise its purchase rights under this
Section 3.8, each Shareholder must within twenty (20) business days after
receipt of written notice from the Company describing in reasonable detail the
capital stock or securities being offered, the purchase price thereof and the
payment terms, deliver a written notice to the Company describing its election
hereunder. Such election shall indicate the number of Offered Shares that the
Shareholder in its sole discretion elects to purchase, which may be all or any
portion of the Offered Shares. The Company shall give the Shareholders no less
than fifteen (15) business days notice of the closing of the sale and purchase
of such shares.

                  (c)   Upon the expiration of the 20-day period described
above, the Company shall be entitled to sell such capital stock or securities
which the Shareholder has not elected to purchase during the ninety (90) days
following such expiration on terms and conditions, including price, no more
favorable to the purchasers thereof than those offered to the Shareholders. Any
capital stock or securities offered or sold by the Company to any person after
such 90-day period must be re-offered to the Shareholders pursuant to the terms
of this Section 3.8.

whereby the Company will utilize media networks of the Ibero Group and its
Affiliates as the preferred choice for its advertising expenditures); (ii) the
Company and the Ibero Group developing Internet sites for Ibero Group's media
networks as a preferred provider; (iii) the Company and the Ibero Group sharing

such opportunities are mutually beneficial for both Ibero Group and the Company.
The Ibero Group and the Company agree that these strategic business
opportunities are intended to be a part of a long-term strategic initiative.

ARTICLE 5.         MISCELLANEOUS

                  5.1.  NOTICES. Any and all notices, designations, consents,
offers, acceptances, or any other communication required or permitted to be
given by any provision of this Agreement shall be deemed to be sufficient if
contained in a written instrument delivered in person or duly sent by telecopier
with acknowledgment of receipt sent by telecopier or delivered in person, as the
case may be, to such party at the address or telecopier number, as the case may
be, set forth on the signature pages hereto. All such notices, requests,
consents and other communications shall be deemed to have been received: (a) in
the case of personal delivery, on the date of receipt; or (b) in the case of
telecopying, on the date of acknowledgment thereof.

                  5.2.  AMENDMENT AND WAIVER. No change or modification of, or
waiver of compliance with, this Agreement shall be valid unless the same shall
be in writing and signed by each of the Shareholders party hereto which holds an
Interest of one percent (1%) or more.

                  5.3.  TERMINATION. This Agreement may be terminated at any
time by an instrument in writing signed by all of the Shareholders party hereto.
This Agreement shall terminate automatically as to any Shareholder which
transfers all of its El Sitio Shares, or upon the occurrence of a Qualifying IPO
(as defined in the Memorandum). Unless sooner terminated, this Agreement shall
terminate ten (10) years from the date hereof, unless, at any time within one
(1) year prior to such date, all of the parties extend its duration for as many
additional periods, each not to exceed ten (10) years, as they may desire.

                  5.4.  NO WAIVER. No failure or delay on the part of the
Shareholders or any of them in exercising any right, between the Company and the
Shareholders or any of them shall operate as a waiver thereof nor shall any
single or partial exercise of any right, power or privilege hereunder preclude
the simultaneous or later exercise of any other right, power or privilege. The
rights and remedies herein expressly provided are cumulative and not exclusive
of any rights or remedies which the Shareholders or any of them would otherwise
have. No notice to or demand on the Company in any case shall entitle the
Company to any other or further notice or demand


                                       17
<PAGE>

in similar or other circumstances or constitute a waiver of the rights of the
Shareholders or any of them to take any other or further action in any
circumstances without notice or demand.

                  5.5.  SPECIFIC PERFORMANCE. Each party to this Agreement
acknowledges that the other parties will suffer irreparable injury in the event
of any breach of any provision of this Agreement and that therefore the remedy
at law for any breach or threatened breach of any such provision of this
Agreement will be inadequate. Accordingly, upon a breach or threatened breach of
any such provision of this Agreement by any party hereto, the other parties
shall, in addition and without prejudice to any of the rights and remedies they
may have, be entitled as a matter of right, without proof of actual damages, to
seek specific performance of such provisions of this Agreement and to such other
injunctive or equitable relief to enforce, or prevent any violations (whether
anticipatory, continuing or future) of, such provisions of this Agreement.

                  5.6.  COUNTERPARTS AND HEADINGS. This Agreement may be
executed in two or more counterparts, each of which shall be deemed to be an
original, but all of which together shall constitute one and the same
instrument. All headings and any cover page or table of contents are inserted
for convenience or reference only and shall not affect its meaning or
interpretation.

                  5.7.  NOUNS AND PRONOUNS. Whenever the context may require,
any pronouns used herein shall include the corresponding masculine, feminine or
neuter forms, and the singular form of nouns and pronouns shall include the
plural and vice-versa. Dollars or $ means the currency of the United States or
its foreign currency equivalent at the time the determination is made.

                  5.8.  EXPENSES. Each of the parties to this Agreement shall
bear its own expenses, including, without limitation, the fees and disbursements
of its respective counsel, in connection with the negotiation and execution of
this Agreement and the consummation of the transactions contemplated hereby.

                  5.9.  GOVERNING LAW. This Agreement will be governed by, and
construed and enforced in accordance with, the laws of the British Virgin
Islands, without regard to its conflict of law rules.

                  5.10. DISPUTE RESOLUTION.

                  (a)   Any and all disputes between or among the parties not
involving any Class B Shareholder arising in connection with or relating in any
way to the validity, construction, meaning, enforceability or performance of
this Agreement shall be settled by binding arbitration in accordance with the
rules of arbitration then in effect (the "ICC Rules") of the International
Chamber of Commerce (the "ICC"). Any party or parties electing to refer a matter
to arbitration pursuant hereto (the "Petitioner") shall promptly deliver written
notice (the "Arbitration Notice") to the other parties that it wishes to
commence an arbitration proceeding under this Section 5.10. The Arbitration
Notice shall set forth the matter being referred to arbitration and the name of
the individual selected by the Petitioner as one of the arbitrators.


                                       18
<PAGE>


                  (b)   There shall be three (3) arbitrators, and each party to
the arbitration shall select one (1) arbitrator. Within twenty (20) days of
receipt of the Arbitration Notice, the other party to such arbitration (the
"Respondent") shall appoint an arbitrator (who shall have appropriate
qualifications in relation to the matter in dispute) and notify the Petitioner
of such appointment and submit its counter statement, if any, of the matter
being referred to arbitration. If the Respondent fails to appoint an arbitrator
within such twenty (20) day period, the Petitioner shall request the ICC
President to appoint a second arbitrator who shall have appropriate
qualifications in relation to the matter in dispute. Within twenty (20) days
after appointment of the second arbitrator, the two arbitrators shall appoint
the third arbitrator. If the two arbitrators fail to appoint the third
arbitrator within such twenty (20) day period, either party to the arbitration
may request that the ICC President appoint the third arbitrator, who shall have
appropriate qualifications in relation to the matter in dispute. All three (3)
arbitrators shall be bilingual (Spanish/English). In the event that there are
more than two (2) parties to such arbitration, all three (3) arbitrators shall
be appointed by the ICC President.

                  (c)   The arbitration proceedings shall be conducted in the
English and Spanish languages in London, England, in accordance with the ICC
Rules, and all documents in connection with any such proceedings shall be
submitted in the English or Spanish languages or with a complete and accurate
English or Spanish (as applicable) language translation. In any arbitration, the
decision of the arbitrators shall be final and binding on the parties to the
arbitration and judgment on the decision may be entered in and enforced in any
court of competent jurisdiction in accordance with the New York Convention on
the Recognition and Enforcement of Arbitral Awards. The substantially prevailing
party in such arbitration, in addition to all other relief provided, shall be
entitled to an award of all its reasonable costs and expenses including attorney
fees and expenses and deposits and payments to the ICC.

                  (d)   Each party hereto hereby agrees that each of the parties
hereto shall have the right to seek appropriate emergency or equitable relief to
preserve the arbitral matter or to otherwise protect its rights pending
resolution of the arbitral matter, whether in New York, New York, Argentina or
in any other jurisdiction.

                  (e)   The parties agree to negotiate in good faith to resolve
any dispute involving the Class B Shareholders regarding arising in connection
with or relating in any way to the validity, construction, meaning,
enforceability or performance of this Agreement. If the negotiations do not
resolve the dispute to the reasonable satisfaction of both parties to the
dispute, then each party shall nominate one senior officer of the rank of Vice
President or higher as its representative. These representatives shall, within
thirty (30) days of a written request by either party to call such a meeting,
meet in person and alone (except for one assistant for each party) and shall
attempt in good faith to resolve the dispute. If the disputes cannot be resolved
by such senior managers in such meeting, the parties agree that they shall, if
requested in writing by either party, meet within thirty (30) days after such
written notification for one day with an impartial mediator and consider dispute
resolution alternatives other than litigation. If an alternative method of
dispute resolution is not agreed upon within thirty (30) days after the one-day
mediation, either party may begin litigation proceedings. This procedure shall
be a prerequisite before taking any additional action hereunder.


                                       19

                  5.11. SUCCESSORS AND ASSIGNS. This Agreement shall be binding
upon and shall inure to the benefit of each of the Shareholders and their
respective executors, administrators and personal representatives and heirs and
their successors and assigns. The rights and obligations of any Shareholder
hereunder shall inure to the benefit of and be binding upon any transferee of
such Shareholder, if (i) such transferee agrees in writing to be bound by the
provisions of this Agreement and (ii) the Interest of such transferee would,
immediately upon becoming a party to this Agreement, equal or exceed five
percent (5%).

                  5.12. SEVERABILITY. In the event that any provision of this
Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, invalid or unenforceable, the remaining provisions hereof shall
nevertheless continue in full force and effect as though the illegal, invalid or
unenforceable provisions were not a part hereof, and the parties shall exert
their best efforts to amend this Agreement to include a provision which is
legal, valid and enforceable and which carries out the original intent of the
parties.

                  5.13. COMPLETE AGREEMENT. This Agreement contains the entire
agreement among the parties with respect to the subject matter hereof and
supersedes all prior and contemporaneous arrangements or understandings, whether
written or oral, between or among any of the parties hereto, with respect to the
subject matter hereof, other than the Registration Rights Agreement and the
Syndication Agreement among the Initial Shareholders, dated as of June 10, 1999.

                  5.14. FURTHER ASSURANCES. Each of the parties to this
Agreement agrees to execute such other documents and take such other action as
may be reasonably necessary to implement and carry out the intent of this
agreement.

                  5.15. CONFLICT WITH MEMORANDUM. In the event that any of the
terms or provisions contained herein conflict with any of the provisions
contained in the Memorandum, the provisions of this Agreement shall govern to
the extent consistent with applicable British Virgin Islands law, as in effect
from time to time.

                  5.16. CONFIDENTIALITY. Each Shareholder (other than Intel
Atlantic, Inc.) covenants and agrees to treat any non-public information
provided to it by the Company concerning the business and finances of the
Company ("Corporate Information") as confidential and agrees further that it
will not use, exploit, reproduce, disclose or provide Corporate Information to
any third party (other than any agents of the Shareholder who are bound by
substantially similar obligations of confidentiality) on its own behalf or
otherwise, except with the consent of the Company or as required by law, legal
process or any federal or state regulatory body having jurisdiction over such
Shareholder. The provisions of this Section 5.16 shall not apply to any
information which:

                  (a)   was within the public domain prior to the time of
disclosure of Corporate Information to the Shareholder or which comes into the
public domain other than as a result of a breach by the Shareholder of this
Section 5.16;


                                       20
<PAGE>


                  (b)   was in the possession of the Shareholder (or any of its
officers, directors, employees, agents, principals, or Affiliates) before the
Shareholder received the Corporate Information;

                  (c)   was rightfully acquired by the Shareholder from a third
party without, to the knowledge of the Shareholder, any restriction or any
obligation of confidentiality; or

                  (d)   was independently developed by the Shareholder without
any use or reference to the Corporate Information.

                  The provisions of this Section 5.16 shall survive the
termination of this Agreement, either in whole or as to any Shareholder, for a
period of two (2) years.

                  The obligations of Intel Atlantic, Inc. with respect to the
treatment of Corporate Information are set forth in Exhibit 4 hereto.

November 9, 1999

Intel Atlantic, Inc.
2200 Mission College Blvd.
Santa Clara, CA  95052


         In consideration of the purchase by Intel Atlantic, Inc. ("Intel") of
555,555.55 shares of Class B Preferred Stock of El Sitio, Inc. ("Company"),
pursuant to a Share Purchase Agreement dated November 9, 1999 (the "Purchase
Agreement"), Company and Intel agree to the terms and obligations of this letter
agreement ("Agreement").

1.       CONFIDENTIALITY

         (a) DISCLOSURE OF TERMS. The terms and conditions of this Agreement,
the Purchase Agreement, the Amended and Restated Shareholders Agreement, dated
November 9, 1999 and the Amended and Restated Registration Rights Agreement,
dated November 9, 1999 (collectively, the "Financing Terms"), including their
existence, shall be considered confidential information and shall not be
disclosed by the Company to any third party except in accordance with the
provisions set forth below.

         (b) PRESS RELEASES, ETC. Within sixty (60) days after the closing of
the transactions contemplated by the Purchase Agreement, the Company may issue a
press release disclosing that the Investors, including Intel, have invested in
the Company; provided that the release does not disclose any of the Financing
Terms and the final form of the press release is approved in advance in writing
by Intel. Intel's name and the fact that Intel is an investor in the Company can
be included in a reusable press release boilerplate statement, so long as Intel
has given the Company its initial approval of such boilerplate statement and the
boilerplate statement is reproduced in exactly the form in which it was
approved. No other announcements regarding Intel in a press release, conference,
advertisement, announcement, professional or trade publication, mass marketing
materials or otherwise to the general public may be made without Intel's prior
written consent.

         (c) PERMITTED DISCLOSURES. Notwithstanding the foregoing, (i) the
Company may disclose any of the Financing Terms to its current or bona fide
prospective investors, employees, investment bankers, lenders, accountants and
attorneys, in each case only where such persons or entities are under
appropriate nondisclosure obligations; (ii) the Company may disclose (other than
in a press release or other public announcement described in subsection (b))
solely the fact that Intel is an investor in the Company to any third parties
without the requirement for the consent of any other party or nondisclosure
obligations; and (iii) Intel may disclose its

investment in the Company and the Financing Terms to third parties or to the
public at its sole discretion and, if it does so, the Company shall have the
right to disclose to third parties any such information disclosed in a press
release or other public announcement by Intel.

         (d) LEGALLY COMPELLED DISCLOSURE. In the event that any party is
requested or becomes legally compelled (including without limitation, pursuant
to securities laws and regulations) to disclose the existence of the agreements
referenced in paragraph (a) above or any of the Financing Terms hereof in
contravention of the provisions of this letter, the Company shall provide Intel
with prompt written notice of that fact so that the appropriate party may seek
(with the cooperation and reasonable efforts of the other) a protective order,
confidential treatment or other appropriate remedy. In such event, the Company
shall furnish only that portion of the information which is legally required and
shall exercise reasonable efforts to obtain reliable assurance that confidential
treatment will be accorded such information to the extent reasonably requested
by Intel.

         (e) OTHER INFORMATION. The provisions of this letter agreement shall be
in addition to, and not in substitution for, the provisions of any separate
nondisclosure agreement executed by any of the parties hereto with respect to
the transactions contemplated hereby. Additional disclosures and exchange of
confidential information between the Company and Intel Corporation or Intel
Atlantic, Inc. shall be governed by the terms of the Corporate Non-Disclosure
Agreement No. 7626010, dated October 18, 1999, executed by the Company and Intel
Corporation, and any Confidential Information Transmittal Records (CITR)
provided in connection therewith.

         (f) All notices required under this section shall be made pursuant to
Section 9.10 of the Purchase Agreement.

2.       MISCELLANEOUS.

         2.1 DEFINITIONS. All capitalized terms used but not otherwise defined
in this Agreement have the meaning defined for such terms in the Purchase
Agreement.

         2.2 GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

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

         2.4 AMENDMENTS AND WAIVERS. This Agreement may not be amended or
modified without the written consent of Intel and the Company, nor shall any
waiver be effective against any party unless in a writing executed on behalf of
such party.

         2.5 SEVERABILITY. If any provision of this Agreement shall be declared
void or unenforceable by any judicial or administrative authority, the validity
of any other provision and of the entire Agreement shall not be affected
thereby.
