                               PROSPECTUS SUMMARY

    YOU SHOULD READ THE FOLLOWING SUMMARY TOGETHER WITH THE MORE DETAILED
INFORMATION AND OUR CONSOLIDATED FINANCIAL STATEMENTS AND THE NOTES TO THOSE
STATEMENTS APPEARING ELSEWHERE IN THIS PROSPECTUS.

                            STARMEDIA NETWORK, INC.

                                  OUR BUSINESS

    StarMedia is the leading Internet media company targeting Latin America and
other Spanish- and Portuguese-speaking markets worldwide. Our network consists
of seven branded Internet properties:

    - StarMedia.com, our flagship Internet media property;

    - StarMedia Acesso, our premium Internet access service;

    - Cade?, a topical directory of Portuguese-language Web sites;

    - LatinRed, one of the largest Spanish-language online communities;

    - OpenChile, a local Chilean portal;

    - Periscopio.com, our personalized search and retrieval property; and

    - Zeek!, a topical directory of Portuguese-language Web sites.

    Through these properties, we offer our users a variety of in-language
interest-specific areas or channels, extensive Web-based community features,
sophisticated search capabilities, online shopping and Internet access services.
Our content covers a broad array of topics of interest to Latin Americans and
other Spanish- and Portuguese-speaking audiences, including local and regional
news, business and sports. We promote user affinity to the StarMedia community
by providing Spanish and Portuguese language e-mail, chat rooms, instant
messaging and personal homepages. We provide our content and community features
to our users for free. We derive our revenues principally from the sale of
advertisements and sponsorships on our network.

    At a time when content on the Internet is overwhelmingly in English, we
offer our users an in-language community experience, combined with a broad array
of Spanish and Portuguese content tailored for regional dialects and local
cultural norms. We develop our product offerings both internally and through
strategic relationships with third parties, including Netscape, Disney, Reuters,
SkyBox and Ziff-Davis. We also provide advertisers and merchants targeted access
to Latin American and other Spanish- and Portuguese-speaking Internet users, an
audience with a highly desirable demographic profile.

    The total number of Web pages our users access on our network, referred to
as our page views, has grown to over 686 million in the three months ended June
30, 1999. In addition, our active e-mail accounts have grown to 1.2 million as
of June 30, 1999.

    Our growing user base provides advertisers and merchants with a highly
attractive platform to reach their target audience and provides us with
additional revenue opportunities. In addition, we believe that the StarMedia
network appeals to advertisers and merchants because of our:

    - focus on Latin America and other Spanish- and Portuguese-speaking markets;

    - powerful brand image across Latin America and in each of our local
      markets; and

    - a user base with a highly attractive demographic profile.

    Consequently, we had 160 advertisers and sponsors on our network during the
three months ended June 30, 1999. Our customers included such leading
advertisers and sponsors as Banco Santander, Bradesco, Ford, Fox Sports America,
IBM, Nokia, Outpost.com, SkyTel, Sony and USA Networks. These named customers,
in the aggregate, accounted for approximately 20% of total revenues in the three
months ended June 30, 1999 and 33% of total revenues for the year ended December
31, 1998.

                                  OUR STRATEGY

    Our objective is to strengthen our position as the leading Internet media
company targeting Latin America and other Spanish- and Portuguese-speaking
markets worldwide by:

    - aggressively extending the recognition of our brands;

    - enhancing and expanding our Spanish and Portuguese content and community
      features;

    - furthering our penetration into additional Spanish- and
      Portuguese-speaking markets;

    - continuing to pursue strategic acquisitions and alliances;

    - expanding our Internet access service to users across Latin America; and

    - developing and deploying next generation content and service distribution
      platforms such as wireless and broadband capabilities.

                                  RISK FACTORS

    THIS OFFERING INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD CAREFULLY CONSIDER
THE RISKS DESCRIBED BELOW BEFORE YOU DECIDE TO BUY OUR COMMON STOCK. IF ANY OF
THE FOLLOWING RISKS ACTUALLY OCCUR, OUR BUSINESS, FINANCIAL CONDITION OR RESULTS
OF OPERATIONS WOULD LIKELY SUFFER. IN THIS CASE, THE TRADING PRICE OF OUR COMMON
STOCK COULD DECLINE, AND YOU MAY LOSE ALL OR PART OF YOUR INVESTMENT.

          RISKS RELATED TO OUR FINANCIAL CONDITION AND BUSINESS MODEL

OUR LIMITED OPERATING HISTORY MAKES EVALUATING OUR BUSINESS DIFFICULT

    We were incorporated in March 1996. We commenced operations in September
1996 and launched the StarMedia network in December 1996. Accordingly, we have
only a limited operating history for you to evaluate our business. You must
consider the risks, expenses and uncertainties that an early stage company like
ours faces. These risks include our ability to:

    - increase awareness of our Internet brands and continue to build user
      loyalty;

    - expand the content and services on our network;

    - attract a larger audience to our network;

    - attract a large number of advertisers from a variety of industries;

    - maintain our current, and develop new, strategic relationships;

    - respond effectively to competitive pressures; and

    - continue to develop and upgrade our technology.

    If we are unsuccessful in addressing these risks, our business, financial
condition and results of operations will be materially and adversely affected.

WE HAVE NEVER MADE MONEY AND EXPECT OUR LOSSES TO CONTINUE

    We have never been profitable. As of June 30, 1999, we had an accumulated
deficit of approximately $96.3 million. We expect to continue to incur
significant losses for the foreseeable future. Although our revenues have grown
in recent quarters, our expenses have grown even faster and we expect to
increase our spending significantly. Accordingly, we will need to generate
significant revenues to achieve profitability. We may not be able to do so.

WE HAVE DERIVED A PORTION OF OUR REVENUES FROM RECIPROCAL ADVERTISING
  AGREEMENTS, WHICH DO NOT GENERATE CASH REVENUE

    We derive a portion of our revenues from reciprocal advertising arrangements
under which we exchange advertising space on our network predominantly for
advertising space on television and radio stations, rather than cash payments.
In the six months ended June 30, 1999, we derived approximately $1.9 million, or
34% of revenues, from these arrangements. In the year ended December 31, 1998,
we derived approximately $2.4 million, or 42% of revenues, from these
arrangements. We expect that revenues from reciprocal advertising arrangements
will continue to account for a portion of our revenues in the foreseeable
future. Reciprocal advertising arrangements do not generate any cash revenues.

YOU SHOULD NOT RELY ON OUR QUARTERLY OPERATING RESULTS AS AN INDICATION OF OUR
  FUTURE RESULTS BECAUSE THEY ARE SUBJECT TO SIGNIFICANT FLUCTUATIONS

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

    - growth and acceptance of the Internet, particularly in Latin America;

    - our ability to attract and retain users;

                                       8
<PAGE>
    - demand for advertising on the Internet in general and on our network in
      particular;

    - our ability to upgrade and develop our systems and infrastructure;

    - technical difficulties that users may experience on our network;

    - technical difficulties or system downtime resulting from the developing
      telecommunications infrastructure in Latin America;

    - competition in our markets;

    - foreign currency exchange rates that affect our international operations;
      and

    - general economic conditions, particularly in Latin America.

    Accordingly, you should not rely on quarter-to-quarter comparisons of our
results of operations as an indication of our future performance. It is possible
that in future periods our results of operations may be below the expectations
of public market analysts and investors. This could cause the trading price of
our common stock to decline.

OUR OPERATING RESULTS MAY ALSO FLUCTUATE DUE TO SEASONAL FACTORS

    The level of use on our network is highly seasonal. This may cause
fluctuations in our revenues and operating results. Visitor traffic on our
network has historically been significantly lower during the first calendar
quarter of the year because it includes the summer months in much of Latin
America during which:

    - our target audience tends to take extended vacations; and

    - schools and universities are generally closed.

As a result, advertisers have historically spent less in the first calendar
quarter. We believe that these seasonal trends will continue to affect our
results of operations. If our expenses increase during these periods, we may not
generate sufficient revenue to offset these expenses.

WE MAY NOT BE ABLE TO OBTAIN SUFFICIENT FUNDS TO GROW OUR BUSINESS

    We intend to continue to grow our business. Because we expect to generate
losses for the foreseeable future, we do not expect that income from our
operations will be sufficient to meet these needs. Therefore, we will likely
have substantial future capital requirements after this offering. Obtaining
additional financing will be subject to a number of factors, including:

    - market conditions;

    - our operating performance; and

    - investor sentiment.

    These factors may make the timing, amount, terms and conditions of
additional financing unattractive for us. If we are unable to raise additional
capital, our growth could be impeded.

                   RISKS RELATED TO OUR MARKETS AND STRATEGY

IF THE INTERNET IS NOT WIDELY ACCEPTED AS A MEDIUM FOR ADVERTISING AND COMMERCE,
  OUR BUSINESS WILL SUFFER

    We expect to derive most of our revenue for the foreseeable future from
Internet advertising, and to a lesser extent, from electronic commerce. If the
Internet is not accepted as a medium for advertising and commerce, our business
will suffer. The Internet advertising market is new and rapidly evolving,
particularly in Latin America. As a result, we cannot gauge its effectiveness or
long term market acceptance as compared with traditional media.

    Advertisers and advertising agencies must direct a portion of their budgets
to the Internet and, specifically, to our network. Many of our current or
potential advertising and electronic commerce partners have limited experience
using the Internet for advertising purposes and

                                       9
<PAGE>
historically have not devoted a significant portion of their advertising budgets
to Internet-based advertising. Advertisers that have invested substantial
resources in other methods of conducting business may be reluctant to adopt a
new strategy that may limit or compete with their existing efforts.

    In addition, companies may choose not to advertise on the StarMedia network
if they do not perceive our audience demographic to be desirable or advertising
on our network to be effective.

THE ACCEPTANCE OF THE INTERNET AS A MEDIUM FOR ADVERTISING DEPENDS ON THE
  DEVELOPMENT OF A MEASUREMENT STANDARD

    No standards have been widely accepted for the measurement of the
effectiveness of Internet advertising. Standards may not develop sufficiently to
support the Internet as an effective advertising medium. If these standards do
not develop, advertisers may choose not to advertise on the Internet in general
or, specifically, on our network. This would have a material adverse effect on
our business, financial condition and results of operations.

SOCIAL AND POLITICAL CONDITIONS IN LATIN AMERICA MAY CAUSE VOLATILITY IN OUR
  OPERATIONS AND ADVERSELY AFFECT OUR BUSINESS

    We have and expect to continue to derive substantially all of our revenues
from the Latin American markets. Social and political conditions in Latin
America are volatile and may cause our operations to fluctuate. This volatility
could make it difficult for us to sustain our expected growth in revenues and
earnings, which could have an adverse effect on our stock price. Historically,
volatility has been caused by:

    - significant governmental influence over many aspects of local economies;

    - political instability;

    - unexpected changes in regulatory requirements;

    - social unrest;

    - slow or negative growth;

    - imposition of trade barriers; and

    - wage and price controls.

We have no control over these matters. Volatility resulting from these matters
may decrease Internet availability, create uncertainty regarding our operating
climate and adversely affect our customers' advertising budgets, all of which
may adversely impact our business.

CURRENCY FLUCTUATIONS AND GENERAL ECONOMIC CONDITIONS IN LATIN AMERICA MAY
  ADVERSELY AFFECT OUR BUSINESS

    The currencies of many countries in Latin America have experienced
substantial depreciation and volatility. The currency fluctuations, as well as
high interest rates, inflation and high unemployment, have materially and
adversely affected the economies of these countries. Poor general economic
conditions in Latin American countries may cause our customers to reduce their
advertising spending, which could adversely impact our business and could cause
our revenue to decline unexpectedly.

WE MAY SUFFER CURRENCY EXCHANGE LOSSES IF LOCAL LATIN AMERICAN CURRENCIES
  DEPRECIATE RELATIVE TO THE U.S. DOLLAR

    Our reporting currency is the U.S. dollar. In a number of cases, however,
customers in Latin America may be billed in local currencies. Our accounts
receivable from these customers will decline in value if the local currencies
depreciate relative to the U.S. dollar. To date, we have not tried to reduce our
exposure to exchange rate fluctuations by using hedging transactions. Although
we may enter into hedging transactions in the future, we may not be able to do
so successfully. In addition, our currency exchange losses may be magnified if
we become subject to exchange control regulations restricting our ability to
convert local currencies into U.S. dollars.

                                       10
<PAGE>
IF INTERNET USE IN LATIN AMERICA AND OTHER SPANISH- AND PORTUGUESE-SPEAKING
  MARKETS DOES NOT GROW, OUR BUSINESS WILL SUFFER

    The Internet market in Latin America and other Spanish- and
Portuguese-speaking markets is in an early stage of development. Our future
success depends on the continued growth of the Internet in these markets. Our
business, financial condition and results of operations will be materially and
adversely affected if Internet usage in these markets does not continue to grow
or grows more slowly than we anticipate. Internet usage in these markets may be
inhibited for a number of reasons, including:

    - the cost of Internet access;

    - concerns about security, reliability, and privacy;

    - ease of use; and

    - quality of service.

UNDERDEVELOPED TELECOMMUNICATIONS INFRASTRUCTURE MAY LIMIT THE GROWTH OF THE
  INTERNET IN LATIN AMERICA AND ADVERSELY AFFECT OUR BUSINESS

    Access to the Internet requires a relatively advanced telecommunications
infrastructure. The telecommunications infrastructure in many parts of Latin
America is not as well-developed as in the United States or Europe. The quality
and continued development of the telecommunications infrastructure in Latin
America will have a substantial impact on our ability to deliver our services
and on the market acceptance of the Internet in Latin America in general. If
further improvements to the Latin American telecommunications infrastructure are
not made, the Internet will not gain broad market acceptance in Latin America.
If access to the Internet in Latin America does not continue to grow or grows
more slowly than we anticipate, our business, financial condition and results of
operations will be materially and adversely affected.

HIGH COST OF INTERNET ACCESS MAY LIMIT THE GROWTH OF THE INTERNET IN LATIN
  AMERICA AND IMPEDE OUR GROWTH

    Each country in Latin America has its own telephone rate structure which, if
too expensive, may cause consumers to be less likely to access and transact
business over the Internet. Although rates charged by Internet service providers
and local telephone companies have been reduced recently in some countries, we
do not know whether this trend will continue. Unfavorable rate developments
could decrease our visitor traffic and our ability to derive revenues from
transactions over the Internet. This could have a material adverse effect on our
business, financial condition and results of operations.

OUR PAN-REGIONAL APPROACH TO CONTENT DELIVERY MAY NOT BE APPEALING TO OUR USERS

    Our target markets are made up of a number of diverse regions that differ
historically, culturally, economically and politically. We generally use a
pan-regional approach to community development and to advertisements. Users,
however, may prefer content and community features which are specifically
created for a local audience using a strictly localized approach over our
pan-regional approach. If users do not find the pan-regional content on our
network appealing, they will decrease in number and advertisers will find our
network an unattractive medium on which to advertise.

WE MAY NOT BE ABLE TO SUCCESSFULLY OR PROFITABLY PROVIDE INTERNET ACCESS
  SERVICES IN LATIN AMERICA

    We recently began to offer Internet access services in Brazil and intend to
offer these services in other Latin American markets during the second half of
1999. We have contracted with AT&T Global Network Services, formerly the IBM
Global Network, to provide these services. We may also acquire or develop
additional Internet access services in the future. We have no experience in
marketing or operating an Internet access service, and

                                       11
<PAGE>
we may not be able to do so successfully. If we are not able to successfully
develop, market or operate our Internet access services, our expenses could
increase substantially without generating significant additional revenue, our
management's time may be wasted and our business may otherwise be materially and
adversely affected.

    In addition, prices for Internet access services have fallen historically, a
trend we expect will continue. Accordingly, we cannot predict to what extent we
may need to reduce our prices to remain competitive or whether we will be able
to sustain our pricing level as our competition increases. This could have a
material adverse effect on our business, financial condition and results of
operations.

WE MAY NOT BE ABLE TO DEVELOP OUR BRANDS AND ATTRACT USERS TO OUR NETWORK

    Maintaining our brands is critical to our ability to expand our user base
and our revenues. We believe that the importance of brand recognition will
increase as the number of Internet sites in our target markets grows. In order
to attract and retain Internet users, advertisers and electronic commerce
partners, we intend to increase substantially our expenditures for creating and
maintaining brand loyalty.

    Our success in promoting and enhancing our brands will also depend on our
success in providing high quality content, features and functionality. If we
fail to promote our brands successfully or if visitors to our network or
advertisers do not perceive our services to be of high quality, the value of our
brands could be diminished. This could have a material and adverse effect on our
business, financial condition and results of operations.

OUR ADVERTISING PRICING MODEL, THAT IS BASED ON THE NUMBER OF TIMES AN
  ADVERTISEMENT IS DELIVERED TO USERS, MAY NOT BE SUCCESSFUL

    Different pricing models are used to sell advertising on the Internet, and
the models we adopt may prove to not be the most profitable. Advertising based
on impressions, or the number of times an advertisement is delivered to users,
currently comprises substantially all of our revenues. To the extent that
minimum guaranteed impression levels are not met, we defer recognition of the
corresponding revenues until guaranteed impression levels are achieved. To the
extent that minimum impression levels are not achieved, we may be required to
provide additional impressions after the contract term, which would reduce our
advertising inventory. This could have a material adverse effect on our
business, financial condition and results of operations.

WE MAY NOT BE ABLE TO SUCCESSFULLY ADAPT TO NEW INTERNET ADVERTISING PRICING
  MODELS

    It is difficult to predict which pricing model, if any, will emerge as the
industry standard. This makes it difficult to project our future advertising
rates and revenues. Our advertising revenues could be adversely affected if we
are unable to adapt to new forms of Internet advertising or we do not adopt the
most profitable form.

WE MAY NOT BE ABLE TO TRACK THE DELIVERY OF ADVERTISEMENTS ON OUR NETWORK IN A
  WAY THAT MEETS THE NEEDS OF OUR ADVERTISERS

    It is important to our advertisers that we accurately measure the
demographics of our user base and the delivery of advertisements on our network.
Companies may choose to not advertise on our network or may pay less for
advertising if they do not perceive our ability to track and measure the
delivery of advertisements to be reliable. We depend on third parties to provide
us with some of these measurement services. If they are unable to provide these
services in the future, we would need to perform them ourselves or obtain them
from another provider. This could cause us to incur additional costs or cause
interruptions in our business during the time we are replacing these services.
We are currently implementing additional systems designed to record information
on our users. If we do not implement these systems successfully, we may not be
able to accurately evaluate the demographic characteristics of our users.

                                       12
<PAGE>
THE LOSS OF ONE OF OUR TOP ADVERTISERS COULD SIGNIFICANTLY REDUCE OUR
  ADVERTISING REVENUE AND MATERIALLY ADVERSELY AFFECT OUR BUSINESS

    In 1998, our top advertiser, Fox Sports America, accounted for approximately
21% of our total advertising revenues. In 1998, our top five advertisers
accounted for approximately 57% of our total revenues. In the six months ended
June 30, 1999, our top 5 advertisers accounted for approximately 33% of our
total revenues. Our business, results of operations and financial condition
could be materially and adversely affected by the loss of one or more of our top
advertisers. If we do not attract additional advertisers, our business,
financial condition and results of operations could be materially adversely
affected.

WE EXPECT TO CONTINUE TO RELY HEAVILY ON ADVERTISING REVENUES AND IF WE DO NOT
  INCREASE OUR ADVERTISING SALES, OUR BUSINESS WILL NOT GROW AS EXPECTED

    We depend on our advertising sales department to maintain and increase our
advertising sales. Our business, financial condition and results of operations
could be materially and adversely affected if our advertising sales department
is not effective. As of June 30, 1999, our advertising sales department
consisted of 99 employees. Although we expect our advertising sales department
to grow, it can take a relatively long period of time before new sales personnel
become productive.

WE MAY NOT BE ABLE TO EFFECTIVELY MANAGE OUR EXPANDING OPERATIONS

    We have recently experienced a period of rapid growth. This has placed a
significant strain on our managerial, operational and financial resources. To
accommodate this growth, we must implement new or upgraded operating and
financial systems, procedures and controls throughout many different locations.
We may not succeed with these efforts. Our failure to expand and integrate these
areas in an efficient manner could cause our expenses to grow, our revenues to
decline or grow more slowly than expected and could otherwise have a material
adverse effect on our business, financial condition and results of operations.

OUR BUSINESS AND GROWTH WILL SUFFER IF WE ARE UNABLE TO HIRE AND RETAIN KEY
  PERSONNEL THAT ARE IN HIGH DEMAND

    We depend on the services of our senior management and key technical
personnel. In particular, our success depends on the continued efforts of our
Chairman and Chief Executive Officer, Fernando J. Espuelas, and our President,
Jack C. Chen. The loss of the services of either executive officer or any of our
key management, sales or technical personnel could have a material adverse
effect on our business, financial condition and results of operations. In
addition, our success is largely dependent on our ability to hire highly
qualified managerial, sales and technical personnel. These individuals are in
high demand and we may not be able to attract the staff we need. The
difficulties and costs in connection with our personnel growth are compounded by
the fact that many of our operations are internationally based.

OUR JOINT VENTURES, ACQUISITIONS AND ALLIANCES MAY STRAIN OUR MANAGERIAL,
  OPERATIONAL AND FINANCIAL RESOURCES AND MAY BE DISRUPTIVE TO OUR BUSINESS

    In the past, we have acquired or developed alliances or joint ventures with
complementary businesses, technologies, services or products. In particular,
during 1999, we have made six acquisitions. Acquisitions could result in a
number of financial consequences, including:

    - potentially dilutive issuances of equity securities;

    - large non-recurring write-offs;

    - reduced cash balances and related interest income;

    - higher fixed expenses which require a higher level of revenues to maintain
      gross margins;

                                       13
<PAGE>
    - the incurrence of debt and contingent liabilities; and

    - amortization expenses related to goodwill and other intangible assets.

    Furthermore, acquisitions involve numerous operational risks, including:

    - difficulties in the integration of operations, personnel, technologies,
      products and the information systems of the acquired companies;

    - diversion of management's attention from other business concerns;

    - diversion of resources from our existing businesses, products or
      technologies;

    - risks of entering geographic and business markets in which we have no or
      limited prior experience; and

    - potential loss of key employees of acquired organizations.

    We could have difficulty in effectively assimilating and integrating these,
or any future joint ventures, acquisitions or alliances, into our operations.
Any difficulties in this process could disrupt our ongoing business, distract
our management and employees, increase our expenses and otherwise adversely
affect our business.

FINANCING FOR FUTURE JOINT VENTURES, ACQUISITIONS OR ALLIANCES MAY NOT BE
  AVAILABLE OR MAY DILUTE EXISTING STOCKHOLDERS

    We do not know if we will be able to identify any future joint ventures,
acquisitions or alliances or that we will be able to successfully finance these
transactions. A failure to identify or finance future transactions may impair
our growth. In addition, to finance these transactions, it may be necessary for
us to raise additional funds through public or private financings. Any equity or
debt financings, if available at all, may impact our operations and, in the case
of equity financings, may result in dilution to existing stockholders.

WE MAY NOT BE ABLE TO COMPETE EFFECTIVELY AGAINST OUR COMPETITORS

    There are many companies that provide Web sites and online destinations
targeted to Latin Americans and Spanish- and Portuguese-speaking people in
general. Competition for visitors, advertisers and electronic commerce partners
is intense and is expected to increase significantly in the future because there
are no substantial barriers to entry in our market.

    Increased competition could result in:

    - lower advertising rates;

    - price reductions and lower profit margins;

    - loss of visitors;

    - reduced page views; or

    - loss of market share.

    Any one of these could materially and adversely affect our business,
financial condition and results of operations.

    In addition, 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. A loss of users to
our competitors may have a material and adverse effect on our business,
financial condition and results of operations.

WE WILL NOT BE ABLE TO ATTRACT VISITORS OR ADVERTISERS IF WE DO NOT CONTINUALLY
  ENHANCE AND DEVELOP THE CONTENT AND FEATURES OF OUR NETWORK

    To remain competitive, we must continue to enhance and improve our content.
In addition, we must:

    - continually improve the responsiveness, functionality and features of our
      network; and

    - develop other products and services that are attractive to users and
      advertisers.

    We may not succeed in developing or introducing features, functions,
products and

                                       14
<PAGE>
services that visitors and advertisers find attractive in a timely manner. This
would likely reduce our visitor traffic and materially and adversely affect our
business, financial condition and results of operations.

WE RELY FOR OUR CONTENT ON THIRD PARTIES WHO MAY MAKE THEIR CONTENT AVAILABLE TO
  OUR COMPETITORS

    We constantly attempt to determine what content, features and functionality
our target audience wants. We rely to a large extent on third parties for our
content, much of which is easily available from other sources. If other networks
present the same or similar content in a superior manner, it would adversely
affect our visitor traffic.

IF WE FAIL TO ESTABLISH AND MAINTAIN STRATEGIC RELATIONSHIPS WITH CONTENT
  PROVIDERS, ELECTRONIC COMMERCE MERCHANTS AND TECHNOLOGY PROVIDERS, WE MAY NOT
  BE ABLE TO ATTRACT AND RETAIN USERS

    We have focused on establishing relationships with leading content
providers, electronic commerce merchants, and technology and infrastructure
providers. Our business depends extensively on these relationships. Because most
of our agreements with these third parties are not exclusive, our competitors
may seek to use the same partners as we do and attempt to adversely impact our
relationships with our partners. We might not be able to maintain these
relationships or replace them on financially attractive terms.

    If the parties with which we have these relationships do not adequately
perform their obligations, reduce their activities with us, choose to compete
with us or provide their services to a competitor, we may have more difficulty
attracting and maintaining visitors to our network and our business, financial
condition and results of operations could be materially and adversely affected.
Also, we intend to actively seek additional relationships in the future. Our
efforts in this regard may not be successful.

        RISKS RELATED TO THE INTERNET AND OUR TECHNOLOGY INFRASTRUCTURE

UNEXPECTED NETWORK INTERRUPTIONS CAUSED BY SYSTEM FAILURES MAY RESULT IN REDUCED
  VISITOR TRAFFIC, REDUCED REVENUE AND HARM TO OUR REPUTATION

    In the past, we have experienced:

    - system disruptions;

    - inaccessibility of our network;

    - long response times;

    - impaired quality; and

    - loss of important reporting data.

    Although we are in the process of improving our network, we may not be
successful in implementing these measures. If we experience delays and
interruptions, visitor traffic may decrease and our brand could be adversely
affected. Because our revenues depend on the number of individuals who use our
network, our business may suffer if our improvement efforts are unsuccessful.

    We maintain our central production servers at the New Jersey data center of
Exodus Communications. A failure by Exodus to protect its systems against damage
from fire, hurricanes, power loss, telecommunications failure, break-ins or
other events, could have a material adverse effect on our business, financial
condition and results of operations.

CONCERNS ABOUT SECURITY OF ELECTRONIC COMMERCE TRANSACTIONS AND CONFIDENTIALITY
  OF INFORMATION ON THE INTERNET MAY REDUCE THE USE OF OUR NETWORK AND IMPEDE
  OUR GROWTH

    A significant barrier to electronic commerce and confidential communications
over the Internet has been the need for security. Internet usage could decline
if any well-publicized compromise of security

                                       15
<PAGE>
occurred. We may incur significant costs to protect against the threat of
security breaches or to alleviate problems caused by these breaches.
Unauthorized persons could attempt to penetrate our network security. If
successful, they could misappropriate proprietary information or cause
interruptions in our services. As a result, we may be required to expend capital
and resources to protect against or to alleviate these problems. Security
breaches could have a material adverse effect on our business, financial
condition and results of operations.

COMPUTER VIRUSES MAY CAUSE OUR SYSTEMS TO INCUR DELAYS OR INTERRUPTIONS AND MAY
  ADVERSELY AFFECT OUR BUSINESS

    Computer viruses may cause our systems to incur delays or other service
interruptions. In addition, the inadvertent transmission of computer viruses
could expose us to a material risk of loss or litigation and possible liability.
Moreover, if a computer virus affecting our system is highly publicized, our
reputation could be materially damaged and our visitor traffic may decrease.

YEAR 2000 PROBLEMS MAY DISRUPT OUR INTERNAL OPERATIONS

    Many currently installed computer systems and software products only accept
two digits to identify the year in any date. Therefore, the year 2000 will
appear as "00", which the system might consider to be the year 1900 rather than
the year 2000. This could result in system failures, delays or miscalculations
causing disruptions to our operations. Our failure to correct a material Year
2000 problem could have a material adverse effect on our business, financial
condition and results of operations.

    We continue to develop testing procedures for all software and other systems
that we believe might be affected by Year 2000 issues. Since third parties
developed and currently support many of the systems that we use, a significant
part of this effort will be to ensure that these third-party systems are Year
2000 compliant. We plan to confirm this compliance through a combination of the
representation by these third parties of their products' Year 2000 compliance,
as well as specific testing of these systems.

                       RISKS RELATED TO LEGAL UNCERTAINTY

WE MAY BECOME SUBJECT TO BURDENSOME GOVERNMENT REGULATIONS AND LEGAL
  UNCERTAINTIES AFFECTING THE INTERNET WHICH COULD ADVERSELY AFFECT OUR BUSINESS

    To date, governmental regulations have not materially restricted use of the
Internet in our markets. However, the legal and regulatory environment that
pertains to the Internet is uncertain and may change. Uncertainty and new
regulations could increase our costs of doing business and prevent us from
delivering our products and services over the Internet. The growth of the
Internet may also be significantly slowed. This could delay growth in demand for
our network and limit the growth of our revenues.

    In addition to new laws and regulations being adopted, existing laws may be
applied to the Internet. New and existing laws may cover issues which include:

    - 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;

    - pornography; and

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

WE MAY BECOME SUBJECT TO CLAIMS REGARDING FOREIGN LAWS AND REGULATIONS WHICH MAY
  BE EXPENSIVE, TIME CONSUMING AND DISTRACTING

    Because we have employees, property and business operations throughout the
world, we are subject to the laws and the court systems of many jurisdictions.
We may become subject to claims based on foreign jurisdictions for violations of
their laws. In addition, these laws may be changed or new laws may be enacted in
the future. International litigation is often expensive, time consuming and
distracting. Accordingly, any of the foregoing could have a material adverse
effect on our business, financial condition and results of operations.

UNAUTHORIZED USE OF OUR INTELLECTUAL PROPERTY BY THIRD PARTIES MAY ADVERSELY
  AFFECT OUR BUSINESS

    We regard our copyrights, service marks, trademarks, trade secrets and other
intellectual property as critical to our success. Unauthorized use of our
intellectual property by third parties may adversely affect our business and our
reputation. We rely on trademark and copyright law, trade secret protection and
confidentiality and/or license agreements with our employees, customers,
partners and others to protect our intellectual property rights. Despite our
precautions, it may be possible for third parties to obtain and use our
intellectual property without authorization. Furthermore, the validity,
enforceability and scope of protection of intellectual property in
Internet-related industries is uncertain and still evolving. The laws of some
foreign countries are uncertain or do not protect intellectual property rights
to the same extent as do the laws of the United States.

DEFENDING AGAINST INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS COULD BE TIME
  CONSUMING AND EXPENSIVE AND, IF WE ARE NOT SUCCESSFUL, COULD SUBJECT US TO
  SIGNIFICANT DAMAGES AND DISRUPT OUR BUSINESS

    We cannot be certain that our products do not or will not infringe valid
patents, copyrights or other intellectual property rights held by third parties.
We may be subject to legal proceedings and claims from time to time relating to
the intellectual property of others in the ordinary course of our business. We
may incur substantial expenses in defending against these third-party
infringement claims, regardless of their merit. Successful infringement claims
against us may result in substantial monetary liability or may materially
disrupt the conduct of our business.

WE MAY BE SUBJECT TO CLAIMS BASED ON THE CONTENT WE PROVIDE OVER OUR NETWORK

    The laws in our target markets relating to the liability of companies which
provide online services, like ours, for activities of their visitors are
currently unsettled. Claims have been made against online service providers and
networks in the past for defamation, negligence, copyright or trademark
infringement, obscenity, personal injury or other theories based on the nature
and content of information that was posted online by their visitors. We could be
subject to similar claims and incur significant costs in their defense. In
addition, we could be exposed to liability for the selection of listings that
may be accessible through our network or through content and materials that our
visitors may post in classifieds, message boards, chat rooms or other
interactive services. It is also possible that if any information provided
through our services contains errors, third parties could make claims against us
for losses incurred in reliance on the information. We offer Web-based e-mail
services, which expose us to potential liabilities or claims resulting from:

                                       17
<PAGE>
    - 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 is expensive, even if they do not
result in liability.

WE MAY BE SUBJECT TO CLAIMS BASED ON PRODUCTS SOLD ON OUR NETWORK

    We have entered into arrangements to offer third-party products and services
on our network under which we may be entitled to receive a share of revenues
generated from these transactions. These arrangements may subject us to
additional claims including product liability or personal injury from the
products and services, even if we do not ourselves provide the products or
services. These claims may require us to incur significant expenses in their
defense or satisfaction. While our agreements with these parties often provide
that we will be indemnified against such liabilities, such indemnification may
not be adequate.

    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 liability 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 business, financial condition and results of
operations or could result in the imposition of criminal penalties. 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.

                         RISKS RELATED TO THIS OFFERING

WE MAY USE THE PROCEEDS OF THIS OFFERING IN WAYS WITH WHICH YOU MAY NOT AGREE

    We have not committed the net proceeds of this offering to any particular
purpose. Our management will therefore have significant flexibility in applying
the net proceeds of this offering, including ways in which stockholders may
disagree. If we do not apply the funds we receive effectively, our accumulated
deficit will increase and we may lose significant business opportunities. See
"Use of Proceeds".

OUR STOCK PRICE IS LIKELY TO BE HIGHLY VOLATILE AND COULD DROP UNEXPECTEDLY

    Following this offering, the price at which our common stock will trade is
likely to be highly volatile and may fluctuate substantially.

    In addition, the stock market has from time to time experienced significant
price and volume fluctuations that have affected the market prices for the
securities of technology companies, particularly Internet companies. As a
result, investors in our common stock may experience a decrease in the value of
their common stock regardless of our operating performance or prospects.

IF OUR STOCK PRICE IS VOLATILE, WE MAY BECOME SUBJECT TO SECURITIES LITIGATION
  WHICH IS EXPENSIVE AND COULD RESULT IN A DIVERSION OF RESOURCES

    In the past, following periods of volatility in the market price of a
particular company's securities, securities class action litigation has often
been brought against that company. Many companies in our industry have been
subject to this type of litigation in the past. We may also become involved in
this type of litigation. Litigation is often expensive and diverts management's
attention and resources, which could have a material adverse effect upon our
business, financial condition and results of operations.

                                       18
<PAGE>
SHARES ELIGIBLE FOR PUBLIC SALE AFTER THIS OFFERING COULD ADVERSELY AFFECT OUR
  STOCK PRICE

    The market price of our common stock could decline as a result of sales by
our existing stockholders of shares of common stock in the market after this
offering, or the perception that these sales could occur. These sales also might
make it difficult for us to sell equity securities in the future at a time and
at a price that we deem appropriate.

OUR CHARTER DOCUMENTS AND DELAWARE LAW MAY INHIBIT A TAKEOVER THAT STOCKHOLDERS
  MAY CONSIDER FAVORABLE

    Provisions in our charter and bylaws may have the effect of delaying or
preventing a change of control or changes in our management that stockholders
consider favorable or beneficial. If a change of control or change in management
is delayed or prevented, the market price of our common stock could suffer.

WE ARE CONTROLLED BY A SMALL GROUP OF OUR EXISTING STOCKHOLDERS, WHOSE INTERESTS
  MAY DIFFER FROM OTHER STOCKHOLDERS

    Our directors, executive officers and affiliates currently beneficially own
approximately 53.5% of the outstanding shares of our common stock, and after the
offering will beneficially own approximately 48.8% of the outstanding shares of
our common stock. Accordingly, they will have significant influence in
determining the outcome of any corporate transaction or other matter submitted
to the stockholders for approval, including mergers, consolidations and the sale
of all or substantially all of our assets, and also the power to prevent or
cause a change in control. The interests of these stockholders may differ from
the interests of the other stockholders.

YOU WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION

    The public offering price per share will significantly exceed the net
tangible book value per share. Accordingly, investors purchasing shares in this
offering will suffer immediate and substantial dilution of their investment.

                    FORWARD-LOOKING STATEMENTS; MARKET DATA

    Many statements made in this prospectus under the captions "Prospectus
Summary", "Risk Factors", "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business" and elsewhere are
forward-looking statements that are not based on historical facts. Because these
forward-looking statements involve risks and uncertainties, there are important
factors that could cause actual results to differ materially from those
expressed or implied by these forward-looking statements, including those
discussed under "Risk Factors".

    This prospectus contains market data related to our business and the
Internet. This market data includes projections that are based on a number of
assumptions. The assumptions include that:

    - no catastrophic failure of the Internet will occur;

    - the number of people online and the total number of hours spent online
      will increase significantly over the next five years;

    - the value of online advertising dollars spent per online user hour will
      increase;

    - the download speed of content will increase dramatically; and

    - Internet security and privacy concerns will be adequately addressed.

    If any one or more of the foregoing assumptions turns out to be incorrect,
actual results may differ from the projections based on these assumptions. The
Internet-related markets may not grow over the next three to four years at the
rates projected by these market data, or at all. The failure of these markets to
grow at these projected rates may have a material adverse effect on our
business, results of operations and financial condition, and the market price of
our common stock.

    The forward-looking statements made in this prospectus relate only to events
as of the date on which the statements are made. We undertake no obligation to
update any forward-looking statement to reflect events or circumstances after
the date on which the statement is made or to reflect the occurrence of
unanticipated events.

                                USE OF PROCEEDS

    The net proceeds we will receive from the sale of the shares of common stock
offered by us are $192.5 million, at a public offering price of $34.00 per share
and after deducting the underwriting discount and estimated offering expenses.
If the underwriters' over-allotment option is exercised in full, the net
proceeds we will receive will be $221.5 million.

    The principal purpose of this offering is to increase our working capital.
As of the date of this prospectus, we have not made any specific expenditure
plans with respect to the proceeds of this offering. Accordingly, our management
will have significant flexibility in applying the net proceeds of the offering.

    We may use a portion of the net proceeds to acquire or invest in
complementary businesses, technologies, services or products; however, we
currently have no commitments or agreements with respect to any such
transactions.
    Pending any use, the net proceeds of this offering will be invested in
short-term, interest-bearing securities.

currently intend to retain future earnings, if any, to finance the expansion of
our business. As a result, we do not anticipate paying any cash dividends in the
foreseeable future.

</TABLE>

    The number of shares of common stock to be outstanding after this offering
is based on the number of shares outstanding as of June 30, 1999. It does not
include:

    - 7,271,533 shares subject to options outstanding as of June 30, 1999 at a
      weighted average exercise price of $2.72 per share;

    - 7,594,831 additional shares that could be issued under our stock option
      plans;

    - 1,500,000 additional shares available for issuance under our employee
      stock purchase plan;

    - 58,689 additional shares of our common stock issued in exchange for
      outstanding shares of series A preferred stock of Webcast, issued by
      Webcast subsequent to June 30, 1999; and

    - 174,418 shares of our common stock and 58,140 shares of our junior
      non-voting convertible preferred stock issued upon the consummation of the
      acquisition of PageCell.

                                    DILUTION

    Our net tangible book value as of June 30, 1999 was approximately $165.4
million, or $2.85 per share of common stock after giving retroactive effect to
the Webcast acquisition. Net tangible book value per share is determined by
dividing the amount of our total tangible assets less total liabilities by the
number of shares of common stock outstanding at that date. Dilution in net
tangible book value per share represents the difference between the amount per
share paid by purchasers of shares of common stock in this offering made and the
net tangible book value per share of common stock immediately after the
completion of this offering.

    After giving effect to the issuance and sale of the shares of common stock
offered by us and after deducting the underwriting discount and estimated
offering expenses payable by us, our net tangible book value as of June 30, 1999
after giving retroactive effect to the Webcast acquisition would have been
$357.9 million, or $5.59 per share. This represents an immediate increase in net
tangible book value of $2.74 per share to existing stockholders and an immediate
dilution of $28.41 per share to new investors purchasing shares in this
offering. The following table illustrates this per share dilution:

    This discussion and table assume no exercise of any stock options
outstanding as of June 30, 1999 and do not include the issuance of (1) 58,689
additional shares of our common stock issued in exchange for outstanding shares
of series A preferred stock of Webcast, issued by Webcast subsequent to June 30,
1999 and (2) 174,418 shares of our common stock and 58,140 shares of our junior
non-voting convertible preferred stock issued upon the consummation of the
acquisition of PageCell. As of June 30, 1999, after giving retroactive effect to
the Webcast acquisition, there were options outstanding to purchase a total of
7,271,533 shares of common stock with a weighted average exercise price of $2.72
per share. To the extent that any of these options are exercised, there will be
further dilution to new investors.

December 31, 1996, the years ended December 31, 1997 and 1998 and the six months
ended June 30, 1999 have been derived from our audited supplemental consolidated
financial statements included elsewhere in this prospectus. The selected
supplemental consolidated statement of operations for the six months ended June
30, 1998 have been derived from the unaudited supplemental consolidated
financial statements included elsewhere in this prospectus. The selected
consolidated balance sheet data as of December 31, 1996 are derived from our
consolidated audited financial statements not included in this prospectus. The
supplemental consolidated statement of operations data includes the acquisitions
of Wass Net and Webcast, which have each been accounted for as a pooling of
interests. Accordingly, our supplemental consolidated financial data includes
for all periods presented the results of Wass Net since its inception on August
29, 1997 and Webcast since its inception on July 24, 1998. The pro forma
statement of operations data for the year ended December 31, 1998 and for the
six months ended June 30, 1999 assumes that the acquisition of KD Sistemas
occurred on January 1, 1998. The unaudited supplemental consolidated 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 position and the consolidated results
of operations for such period. Results of operations for the six months ended
June 30, 1999 are not necessarily indicative of the results that may be expected
for the entire year or for any future period. The selected supplemental
consolidated financial data set forth below should be read in conjunction with
"Management's Discussion and Analysis of Financial Condition and Results of
Operations", the pro forma condensed consolidated financial statements and the
consolidated financial statements and the notes to those statements and
supplemental consolidated financial statements and notes to those statements
included elsewhere in this prospectus.

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

    THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH OUR FINANCIAL
STATEMENTS AND NOTES TO THOSE STATEMENTS AND OTHER FINANCIAL INFORMATION
APPEARING ELSEWHERE IN THIS PROSPECTUS.

                                    OVERVIEW

    StarMedia is the leading Internet media company targeting Latin America and
other Spanish- and Portuguese- speaking audiences worldwide. We were
incorporated in March 1996 and commenced operations in September 1996. For the
period from our inception through December 1996, we did not generate any
revenues, incurred minimal operating expenses and focused our operating
activities on the development of the StarMedia network.

    We launched our network in December 1996. During 1997, we continued the
development of the StarMedia network and related technology infrastructure and
also focused on recruiting personnel, raising capital and developing content to
attract and retain users. In 1998, we:

    - improved and upgraded our services;

    - expanded our production staff;

    - built a direct sales force; and

    - increased our marketing activities in order to build the StarMedia brand.

    In March and April 1999, we acquired two leading Brazilian Internet guides,
Zeek!, otherwise known as Achei, and Cade?, otherwise known as KD Sistemas,
which primarily categorize and review Portuguese-language Web sites. The
aggregate purchase price paid by us for these acquisitions was approximately
$6.1 million plus $0.9 million due before March 2000. We are obligated to make
additional payments, estimated to be up to $6.4 million, to the former
stockholders of KD Sistemas if various performance targets are achieved. These
acquisitions were accounted for as purchases.

    Effective May 1999, we acquired LatinRed, otherwise known as Wass Net, a
Spanish-language online community offering e-mail, chat, classified, bulletin
boards, home pages and search capabilities. We issued 1,133,334 shares of our
common stock for all of the outstanding capital stock of Wass Net. This
acquisition was accounted for as a pooling of interests.

    In June 1999, we acquired all of the outstanding stock of OpenChile,
otherwise known as Servicios Interactivos Limitada, for 20,000 shares of our
common stock. This acquisition was accounted for as a purchase.

    In September 1999, we acquired Webcast, a streaming media company focused on
the global delivery of audio, video and other Internet-based interactive media.
We issued 842,887 shares of our common stock for all of the outstanding capital
stock of Webcast. This acquisition was accounted for as a pooling of interests,
which requires the restatement of all relevant periods as if StarMedia and
Webcast had always been combined. Accordingly, the following discussion reflects
the combined results of operations of StarMedia and Webcast. The only
significant effect of the restatement was the inclusion of Webcast's revenues of
$411,000 for the year ended December 31, 1998 and $175,000 for the six months
ended June 30, 1999 as well as Webcast's net loss of $15,000 for the year ended
December 31, 1998 and $212,000 for the six months ended June 30, 1999.

    In September 1999, we purchased substantially all of the assets of PageCell
International Holdings, Inc., a provider of advanced mobile technologies and
services, in exchange for common stock and junior non-voting convertible
preferred stock of the Company valued at $10 million at the closing date and
additional consideration valued at up to $15 million upon the achievement of
certain quarterly performance related targets through December 2000.

    To date, we have derived our revenues primarily from the sale of
advertisements and

                                       26
<PAGE>
sponsorships on our network as well as consulting and technical services.

    Advertising revenues are derived principally from:

    - advertising arrangements under which we receive revenues based on a
      cost-per-thousand-impressions basis, commonly referred to as CPMs;

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

    - reciprocal advertising arrangements, under which we exchange advertising
      space on our network predominantly for advertising on television and radio
      stations; and

    - design, coordination and integration of advertising campaigns and
      sponsorships to be placed on our network.

    Advertising and sponsorship rates depend on:

    - whether the impressions are for general audiences or targeted audiences;

    - the size and placement of the advertisement; and

    - the number of guaranteed impressions, if any.

    Advertising revenues are recognized ratably in the period in which the
advertisement is displayed, provided that no significant obligations remain and
collection of the resulting receivable is probable. To the extent 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 sponsorship arrangements are
recognized ratably over the contract term, provided that we have no significant
obligations remaining. Revenue related to the design, coordination and
integration of content under sponsorship arrangements are recognized ratably
over the contract term or using the percentage of completion method if the
revenue for the services is fixed. Under some of our content arrangements, we
have agreed to pay a portion of the advertising revenue derived from the related
content to the content provider.

    We have entered into reciprocal advertising arrangements with various media
companies, including Fox Sports America and MTV Latin America. We do not receive
any cash payments for these arrangements. We entered into these agreements to
enhance our marketing efforts and to extend our marketing presence beyond the
ten major markets in which our paid advertising is concentrated. Revenues and
expenses from 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 at the
value of the television advertising received when our advertisements are
broadcast, which is typically in the same period as the advertisements are run
on our network. These expenses are included in our sales and marketing expenses.
To date, we have engaged in no reciprocal advertising arrangements under which
we have received online advertising.

    In addition to advertising revenues, we derive revenues from online commerce
transactions conducted through our network. Revenues from our share of the
proceeds from sales are recognized on notification of sales attributable to our
network. To date, commerce revenues have not been significant. We anticipate
that, although commerce revenues will increase in future periods, the
substantial majority of our revenues will continue to be derived from the sale
of advertising on our network.

    We have a limited operating history for you to use as a basis for evaluating
our business. You must consider the risks and difficulties frequently
encountered by early stage companies like us in new and rapidly evolving
markets, including the Internet advertising market.

    We have incurred significant net losses and negative cash flows from
operations since our inception. At June 30, 1999, we had an accumulated deficit
of $96.3 million. These losses have been funded primarily through the issuance
of our equity securities. We intend to continue to invest heavily in marketing
and brand development, content enhancements, and technology and infrastructure
development. As a result, we believe that we will continue to incur net losses
and negative cash flows from operations for the foreseeable future. Moreover,
the rate at which these losses will be incurred may increase from current
levels.

    We recorded cumulative deferred compensation of approximately $25.0 million
through June 30, 1999, which represents the difference between the exercise
price of some stock options granted in 1998 and 1999, and the fair market value
of the underlying common stock at the date of grant. The difference is recorded
as a reduction of stockholders' equity and amortized over the vesting period of
the applicable options. Options granted through February 1999 typically vest
over three years, although a portion of those options vested immediately.
Options granted after February 1999 generally vest over four years. Of the total
deferred compensation amount, approximately $10.4 million and $3.0 million was
amortized during the year ended December 31, 1998 and the six months ended June
30, 1999, respectively. The amortization of deferred compensation is recorded as
an operating expense. As a result, we currently expect to amortize the following
amounts of deferred compensation annually:

    - 1999--$6.2 million;

    - 2000--$5.0 million;

    - 2001--$2.8 million;

    - 2002--$700,000; and

    - 2003--$50,000.

                             RESULTS OF OPERATIONS

                           SIX MONTHS ENDED JUNE 30,
                                 1999 AND 1998

REVENUE

    Revenues increased to $5.5 million for the six months ended June 30, 1999
from $850,000 for the six months ended June 30, 1998. The increase in revenues
was primarily due to an increase in the volume of advertising impressions and
sponsorships sold. During 1999, we continued to:

    - expand our sales force;

    - increase the number of impressions available on our network by adding
      channels and by increasing our marketing efforts; and

    - expand through acquisitions.

    In the six months ended June 30, 1998, four advertisers each accounted for
greater than 10% of total revenues. For the six months ended June 30, 1999, no
advertiser accounted for more than 10% of our revenue. For the six months ended
June 1998, our top five advertisers accounted for 81% of our revenue. For the
six months ended June 1999, our top five advertisers accounted for 33% of our
revenue. In the six months ended June 30, 1999, we derived approximately $1.9
million, or 35% of total revenues, from reciprocal advertising arrangements. We
do not receive any cash payments for these arrangements.

OPERATING EXPENSES

    PRODUCT AND TECHNOLOGY.  Product and technology expenses include:

    - personnel costs;

    - hosting and telecommunication costs; and

    - content acquisition fees and revenue sharing arrangements related to
      agreements with third-party content providers under which we pay
      guaranteed fees and/or a portion of our revenues.

                                       28
<PAGE>
    For the six months ended June 30, 1999, product and technology expenses
increased to $10.0 million, or 182% of total revenues, from $3.2 million, or
376% of total revenues, for the six months ended June 30, 1998. The increase was
primarily due to an increase of approximately $2.9 million related to staffing
levels and approximately $1.3 million to enhance the content and features of the
StarMedia network.

    We have, to date, expensed all product and technology costs as 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 and
technology personnel and to make additional investments in product development
and technological infrastructure. We expect that product expenditures will
continue to increase in absolute dollars in future periods.

    SALES AND MARKETING.  Sales and marketing expenses consist primarily of:

    - advertising costs, including the costs of advertisements placed on various
      television networks under our reciprocal advertising arrangements;

    - salaries and commissions of sales and marketing personnel;

    - public relations costs; and

    - other marketing-related expenses.

    Sales and marketing expenses increased to $22.9 million, or 416% of total
revenues, for the six months ended June 30, 1999 from $6.0 million, or 706% of
total revenues, for the six months ended June 30, 1998.

    The increase in sales and marketing expenses was primarily attributable to:

    - expansion of our advertising, public relations and other promotional
      expenditures related to our branding campaign of approximately $11.1
      million; and

    - higher personnel expenses, including sales commissions, of approximately
      $3.4 million.

    We expect sales and marketing expenses will continue to increase in absolute
dollars for the foreseeable future as we:

    - continue our branding strategy;

    - expand our direct sales force;

    - hire additional marketing personnel; and

    - increase expenditures for marketing and promotion.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist
primarily of:

    - salaries and benefits;

    - costs for general corporate functions, including finance, accounting and
      facilities; and

    - fees for professional services.

    General and administrative expenses increased to $6.7 million, or 122% of
total revenues, for the six months ended June 30, 1999, from $1.0 million, or
118% of total revenues, for the six months ended June 30, 1998. The increase in
general and administrative expenses was primarily due to increased salaries and
related expenses associated with the hiring of additional personnel of
approximately $2.1 million, additional rental costs of approximately $600,000
and additional taxes and insurance charges of approximately $500,000.

    General and administrative expenses for the six months ended June 30,1999
include one-time charges of $1.0 million related to the acquisition of Wass Net.
Since the acquisition was accounted for as a pooling of interests, these costs
were expensed at the consummation of the acquisition.

    We expect that we will incur additional general and administrative expenses
as we hire additional personnel and incur additional costs related to the growth
of our business and our operation as a public company.

                                       29
<PAGE>
Accordingly, we anticipate that general and administrative expenses will
continue to increase in absolute dollars in future periods.

DEPRECIATION AND AMORTIZATION

    Depreciation and amortization expenses increased to $1.6 million, or 29% of
total revenues, for the six months ended June 30, 1999 from $248,000, or 29% of
total revenues, for the six months ended June 30, 1998. The dollar increases
were primarily attributable to the increase in fixed assets of approximately
$6.3 million during 1999 and $5.9 million during 1998. We also incurred goodwill
amortization expenses of $0.5 million related to the acquisitions of Achei and
KD Sistemas. We expect that depreciation and amortization expenses will continue
to increase as we build the structure necessary to improve our products and
acquire other businesses.

STOCK-BASED COMPENSATION EXPENSE

    We recorded additional deferred compensation of $6.0 million during the six
months ended June 30, 1999. Of the cumulative deferred compensation amount, $3.0
million was recorded as an expense during the six months ended June 30, 1999.
The unamortized balance is being amortized over the vesting period for the
individual options, which is typically three years for options issued earlier
than February 1999 and four years for options issued since that date.

INTEREST INCOME, NET

    Interest income, net includes income from our cash and investments. Net
interest income increased from $90,000 for the six months ended June 30, 1998 to
$1.1 million for the six months ended June 30, 1999. Interest income increased
as a result of capital raised from the sale of preferred shares in 1998, the
issuance of 3.7 million shares of common stock to a group of third party
investors in April and May 1999, and the initial public offering of shares of
our common stock in May 1999.

YEARS ENDED DECEMBER 31, 1998 AND 1997 AND THE PERIOD FROM MARCH 5, 1996
  (INCEPTION) TO DECEMBER 31, 1996

REVENUES

    Revenues increased to $5.8 million for the year ended December 31, 1998 from
$472,000 for the year ended December 31, 1997. We did not have any revenue for
the period from March 5, 1996 (inception) to December 31, 1996. The increase in
revenues was primarily due to an increase in the volume of advertising
impressions and sponsorships sold. During 1998, we:

    - expanded our sales force; and

    - increased the number of impressions available on our network by adding
      channels and by increasing our marketing efforts.

    In 1997, three advertisers each accounted for greater than 10% of total
revenues and the five largest advertisers accounted for 98% of total revenues.
In 1998, two advertisers, Netscape and Fox Latin America, each accounted for
greater than 10% of total revenues and the five largest advertisers accounted
for 57% of total revenues. In 1998, 42% of our total revenues were derived from
reciprocal advertising arrangements with our media partners, which consist
primarily of television network operators. We do not receive any cash payments
from these arrangements. We have not engaged in any reciprocal advertising
arrangements under which we received online advertising. Electronic commerce
revenues were not material during these periods.

OPERATING EXPENSES

    PRODUCT AND TECHNOLOGY.  Product and technology expenses increased to $7.1
million, or 122% of total revenues, for the year ended December 31, 1998, from
$1.2 million, or 254% of total revenues, for the year ended December 31, 1997.
We incurred $36,000 of product and technology expenses during 1996. The increase
in product and technology expenses was primarily attributable to an increase of
approximately $3.1 million in 1998

                                       30
<PAGE>
and $668,000 in 1997 related to staffing levels required to support the
StarMedia network and related systems and approximately $1.5 million in 1998 and
$310,000 in 1997 to enhance the content and features on the StarMedia network.
We have, to date, expensed all product and technology costs as incurred.

    SALES AND MARKETING.  Sales and marketing expenses increased to $29.3
million, or 505% of total revenues, for the year ended December 31, 1998, from
$2.1 million, or 445% of total revenues, for the year ended December 31, 1997,
and $12,000 during 1996. The increases in sales and marketing expenses were
primarily attributable to:

    - expansion of our advertising, public relations and other promotional
      expenditures related to our aggressive branding campaign of approximately
      $22.3 million in 1998 and $1.7 million in 1997; and

    - higher personnel expenses, including sales commissions, of approximately
      $2.9 million in 1998 and $222,000 in 1997.

    Sales and marketing expenses as a percentage of total revenues have
increased as a result of the continued development and implementation of
StarMedia's branding and marketing campaign.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
to $4.8 million, or 83% of total revenues, for the year ended December 31, 1998,
from $650,000, or 138% of total revenues, for the year ended December 31, 1997,
and $78,000 during 1996. The increase in general and administrative expenses was
primarily due to increased salaries and related expenses associated with the
hiring of additional personnel of approximately $1.4 million in 1998 and
$200,000 in 1997 to support the growth of our business. General and
administrative expenses decreased on a percentage basis because of the growth in
revenues.

DEPRECIATION AND AMORTIZATION

    Depreciation and amortization expenses increased to $785,000, or 14% of
revenues, for the year ended December 31, 1998, from $38,000, or 8% of revenues,
for the year ended December 31, 1997 and from $2,000 during 1996. The dollar
increases were primarily attributable to the increase in fixed assets of
approximately $5.9 million during 1998 and $270,000 during 1997.

STOCK-BASED COMPENSATION EXPENSE

    We recorded deferred compensation of $19.1 million during the year ended
December 31, 1998. Of this amount, $10.4 million was recorded as an expense in
1998. The unamortized balance is being amortized over the vesting period for the
individual options, which is typically three years.

INTEREST INCOME, NET

    Interest income, net includes income from our cash and investments. Interest
income, net increased to $667,000 for the year ended December 31, 1998 from
$34,000 for the year ended December 31, 1997. We did not record any interest
income, net during 1996. The increase in interest income was primarily due to
higher average cash, cash equivalent and investment balances as a result of
capital received from the sale of preferred stock in the first and third
quarters of 1998.

LIQUIDITY AND CAPITAL RESOURCES

    To date, we have primarily financed our operations through the sale of our
equity securities. At June 30, 1999, we had $164.7 million in cash and cash
equivalents, an increase of $111.6 million from December 31, 1998.

    In the six months ended June 30, 1999, we used $36.0 million in operating
activities, mostly related to our $37.7 million loss during the period which
included non-cash activities such as $1.6 million in depreciation and
amortization and $3.0 million in non-cash charges related to stock option
grants. In the

                                       31
<PAGE>
six months ended June 30, 1998, we used $7.0 million in operating activities,
consisting mostly of $12.8 million for our net loss, partly offset by $3.2
million in non-cash charges related to stock option grants and $3.1 million in
additional liabilities. Net cash used in operating activities was $30.7 million
for the year ended December 31, 1998, $3.3 million for the year ended December
31, 1997 and $127,000 for 1996. To date, we have experienced significant
negative cash flows from operating activities. Net cash used in operating
activities resulted primarily from our net operating losses, offset in part by:

    - the amortization of deferred compensation;

    - depreciation and amortization;

    - increases in accrued expenses and accounts payable; and

    - deferred revenues.

    For the six months ended June 30, 1999, we used $11.1 million in investing
activities, including $6.0 million for fixed assets and $5.1 million in
connection with acquisitions and related costs. Net cash used in investing
activities was $4.7 million for the year ended December 31, 1998, $283,000 for
the year ended December 31, 1997 and $30,000 during 1996. Net cash used in
investing activities during 1996, 1997 and 1998 resulted primarily from the
purchase of fixed assets.

    Net cash provided by financing activities was $159.1 million for the six
months ended June 30, 1999, $88.1 million for the year ended December 31, 1998,
$3.8 million for the year ended December 31, 1997 and $387,000 during 1996. Net
cash provided by financing activities during 1997 and 1998 consisted primarily
of proceeds from the sale of preferred stock. In April and May 1999, we
completed the sale of 3,727,272 shares of our common stock for $41 million. In
May 1999, we raised approximately $110.4 million, net of underwriting discounts
and commissions and related expenses, from the initial public offering of shares
of our common stock. We also entered into a credit line, utilizing $5.1 million
of a $12.0 million facility.

    Our principal commitments consist of obligations outstanding under capital
and operating leases. We expect our capital expenditures will increase
significantly in the future as we make technological improvements to our system
and technical infrastructure.

    In March 1999, we entered into a $12.0 million credit line for the
acquisition of computer equipment and furniture and fixtures. At June 30, 1999,
approximately $4.7 million was outstanding under the equipment line. Amounts
outstanding are payable in monthly installments of principal and interest of
approximately $170,000, bear interest at approximately 13.6% per annum and are
secured by certain computer equipment and furniture and fixtures. The credit
line requires us to maintain at least $10 million in cash and cash equivalents.

    We have entered into an agreement with AT&T Global Network Services,
formerly IBM Global Network, under which we can offer Internet access services
in Argentina, Brazil, Chile, Colombia and Mexico. Under the agreement, we are
obligated to pay AT&T a minimum of approximately $4.3 million in 1999 and
approximately $16.0 million in 2000.

    Our capital requirements depend on numerous factors, including:

    - market acceptance of our services;

    - the amount of resources we devote to investments in the StarMedia network;

    - marketing and selling our services; and

    - promoting our brand.

    We have experienced a substantial increase in our capital expenditures and
operating lease arrangements since our inception consistent with the growth in
our operations and staffing. We anticipate that this will continue for the
foreseeable future. Additionally, we will continue to evaluate possible
investments in businesses, products and technologies, and plan to expand our
sales and marketing programs and conduct more aggressive brand promotions.

                                       32
<PAGE>
    We believe that our current cash and cash equivalents will be sufficient to
meet our anticipated cash needs for working capital and capital expenditures for
at least the next 12 months. If cash generated from operations is insufficient
to satisfy our liquidity requirements, we may seek to sell additional equity or
debt securities or establish an additional credit facility. The sale of
additional equity or convertible debt securities could result in additional
dilution to our stockholders. The incurrence of additional indebtedness would
result in increased fixed obligations and could result in operating 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

    The Year 2000 issue refers to the potential for system and processing
failures of date-related calculations, and is the result of computer-controlled
systems using two digits rather than four to define the applicable year. For
example, computer programs that have time-sensitive software may recognize a
date using "00" as the year 1900 rather than the year 2000. This could result in
system failure or miscalculations causing disruptions of operations, including,
among other things, a temporary inability to process transactions, send
invoices, or engage in similar normal business activities.

STATE OF READINESS

    We have made a preliminary assessment of the Year 2000 readiness of our
operating, financial and administrative systems, including the hardware and
software that support our systems. As part of our assessment plan, we are
evaluating our date-dependent code, internally-developed software, software
developed by third parties and hardware. We plan to complete this evaluation by
October 1999. All internally-developed code will be checked, and any problematic
code identified, fixed and tested by November 1999. All material
externally-developed software that is not Year 2000 compliant will be upgraded
or replaced by November 1999. More specifically:

    - We are quality assurance testing our internally-developed proprietary
      software and systems related to the delivery of our service to our users.
      We plan to complete this testing by November 1999.

    - We have contacted our principal third-party vendors and licensors of
      material hardware, software, and services that are related to the delivery
      of our services to our users, and requested their confirmation of our Year
      2000 compliance of the software, hardware and services they provide to us.
      All of these contacted vendors and licensors have notified us that the
      hardware, software and services that they have provided to us are Year
      2000 compliant.

    - We have contacted our principal vendors of material non-information
      technology systems and services used by us, and requested their
      confirmation of the Year 2000 compliance of their systems and services. We
      have received notification from the majority of these vendors that the
      systems and services that they have provided to us are Year 2000
      compliant. By the end of the third quarter of 1999, we will either have
      received this confirmation from the remaining vendors or have replaced the
      systems and services they provide with compliant systems and services.

    - We are formulating repair or replacement requirements and implementing
      corrective measures. These requirements will be completed by October 1999,
      and, if necessary, corrective measures and repair procedures will be
      implemented by the end of November 1999.

    - We are currently evaluating the need for, and preparing and implementing a
      contingency plan, if required. The results of our assessment and
      simulation testing will be taken into account when we determine the need
      for and the extent of any contingency plans. We

                                       33
<PAGE>
      plan to finalize our contingency plans, if any, by November 1999.

COSTS

    To date, we have spent an immaterial amount on Year 2000 compliance issues
but expect to incur an additional $200,000 to $350,000 in connection with
identifying, evaluating and addressing Year 2000 compliance issues. Most of our
expenses have related to, and are expected to continue to relate to, the
operating costs associated with time spent by employees and consultants in the
evaluation process and Year 2000 compliance matters generally. Such expenses, if
higher than anticipated, could have a material adverse effect on our business,
results of operations, and financial condition.

RISKS

    To the extent that our assessment is finalized without identifying any
additional material non-compliant IT 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 telecommunications or electrical
failure. Such a failure could prevent us from operating our business, prevent
users 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, or other business interruptions of a material nature, as
well as claims of mismanagement, misrepresentation, or breach of contract.

CONTINGENCY PLAN

    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 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 vendors and service providers will be taken into
account in determining the need for and nature and extent of any contingency
plans. We intend to develop any required contingency plans by November 1999.

FORWARD-LOOKING STATEMENTS

    The Year 2000 discussion above is provided as a "Year 2000 Readiness
Disclosure" as defined in the Year 2000 Information and Readiness Disclosure Act
of 1998 (Public Law 105-271, 112 Stat. 2386) enacted on October 19, 1998 and
contains forward-looking statements. These statements are based on management's
best current estimates, which were derived from a number of assumptions about
future events, including the continued availability of resources,
representations received from third parties and other factors. However, we
cannot assure you that these estimates will be achieved, and our actual results
could differ materially from those anticipated. Specific factors that might
cause material differences include:

    - the ability to identify and remediate all relevant systems;

    - results of Year 2000 testing;

    - adequate resolution of Year 2000 issues by governmental agencies,
      businesses and other third parties who are our outsourcing service
      providers, suppliers, and vendors;

    - unanticipated system costs; and

    - our ability to implement adequate contingency plans.

                         INFLATION AND FOREIGN CURRENCY
                              EXCHANGE RATE LOSSES

    To date, our results of operations have not been impacted materially by
inflation in the U.S. or in the countries that comprise Latin America.

    Although a substantial portion of our revenues are denominated in U.S.
dollars, an increasing percentage of our revenues are denominated in foreign
currencies. As a result,

                                       34
<PAGE>
our revenues may be impacted by fluctuations in these currencies and the value
of these currencies relative to the U.S. dollar. In addition, a portion of our
monetary assets and liabilities and our accounts payable and operating expenses
are denominated in foreign currencies. Therefore, we are exposed to foreign
currency exchange risks. However, revenues derived from foreign currencies
historically have not comprised a material portion of our revenues. As a result,
we have not tried to reduce our exposure to exchange rate fluctuations by using
hedging transactions. However, we may choose to do so in the future. We may not
be able to do this successfully. Accordingly, we may experience economic loss
and a negative impact on earnings and equity as a result of foreign currency
exchange rate fluctuations.

                        RECENT ACCOUNTING PRONOUNCEMENTS

    We adopted the provisions of Statement of Financial Accounting Standards
("SFAS") No. 130, "Reporting Comprehensive Income" as of January 1, 1998. SFAS
No. 130 requires us to report in our financial statements, in addition to our
net income (loss), comprehensive income (loss), which includes all changes in
equity during a period from non-owner sources including, as applicable, foreign
currency items, minimum pension liability adjustments and unrealized gains and
losses on investments in debt and equity securities.

    In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 131, "Disclosure About Segments of an Enterprise and Related Information".
SFAS No. 131 establishes standards for the way that public business enterprises
report information about operating segments. It also establishes standards for
related disclosures about products and services, geographic areas and major
customers. SFAS No. 131 is effective for fiscal years beginning after December
15, 1997. We have determined that we do not have any separately reportable
business segments.

    In June 1998, the FASB issued 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, the 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. The statement is not expected to affect us as we currently
do not have any derivative instruments or hedging activities.

                                    BUSINESS

                                    OVERVIEW

    StarMedia is the leading Internet media company targeting Latin America and
other Spanish- and Portuguese-speaking markets worldwide. Our network consists
of seven branded Internet properties:

- - StarMedia.com, our flagship Internet media property;

- - StarMedia Acesso, our premium Internet access service;

- - Cade?, a topical directory of Portuguese-language Web sites;

- - LatinRed, one of the largest Spanish-language online communities;

- - OpenChile, a local Chilean portal;

- - Periscopio.com, our personalized search and retrieval property; and

- - Zeek!, a topical directory of Portuguese-language Web sites.

    Through these properties, we offer our users a variety of in-language
interest-specific areas or channels, extensive Web-based community features,
sophisticated search capabilities, online shopping and Internet access services.
Our content covers a broad array of topics of interest to Latin Americans and
other Spanish- and Portuguese-speaking audiences, including local and regional
news, business and sports. We promote user affinity to the StarMedia community
by providing Spanish and Portuguese language e-mail, chat rooms, instant
messaging and personal homepages. We provide our content and community features
to our users for free. We derive our revenues principally from the sale of
advertisements and sponsorships on our network.

    At a time when content on the Internet is overwhelmingly in English, we
offer our users an in-language community experience, combined with a broad array
of Spanish and Portuguese content tailored for regional dialects and local
cultural norms. As a result, we provide advertisers and merchants targeted
access to Latin American and other Spanish-and Portuguese-speaking Internet
users, an audience with a highly desirable demographic profile.

                              INDUSTRY BACKGROUND

THE GROWTH OF THE INTERNET AND ONLINE ADVERTISING AND COMMERCE

    The Internet has developed into a significant global mass medium that allows
millions of people worldwide to find information, interact with others and
conduct business electronically. International Data Corporation, or IDC,
estimates that the number of Internet users worldwide will grow from
approximately 142 million at the end of 1998 to approximately 399 million by the
end of 2002, representing a compound annual growth rate of 29%. The Internet has
also emerged as an attractive new medium for advertisers. The Internet allows
advertisers to target desired demographic groups or consumers in specific
geographic locations. It also allows them to interact more effectively with
consumers and capture valuable data about buying patterns, preferences and
demands. According to Jupiter Communications, the dollar value of Internet
advertising in the U.S. is expected to increase from $2.1 billion in 1998 to
approximately $8.8 billion in 2002, representing a compound annual growth rate
of 43%. The growth in the use of the Internet is also providing businesses with
a platform to conduct electronic commerce. According to IDC, spending on the
Internet is expected to increase from $50.4 billion in 1998 to approximately
$733.6 billion in 2002, representing a compound annual growth rate of 95%.

INTERNET USE IN LATIN AMERICA

    Latin America is comprised of 23 countries with a total population of
approximately 500 million people. This region consists of the following
countries:

- - Argentina             - Guyana
- - Belize                - Guatemala

- - French Guiana
</TABLE>

                                       36
<PAGE>
    Although divided by geographical and political boundaries, Latin Americans
share many cultural affinities, including common languages and religions, as
well as a similar heritage. A majority of Latin Americans speak Spanish or
Portuguese, with only a small portion of the population being proficient in
English.

    A substantial portion of the buying power in Latin America is concentrated
within 20% of the population, according to Strategy Research Corporation. This
group of approximately 100 million people controls an estimated 60% of the
overall buying power in Latin America and enjoys a standard of living comparable
to the populations of Germany and Great Britain. As a result, the Latin American
market represents a highly desirable demographic profile for advertisers and
businesses. According to a study published in July 1999 by Zenith Media, overall
advertising spending across all media in Latin America was $24 billion in 1998
and is estimated to grow to $26 billion in 2001. According to Forrester
Research, Internet advertising in Latin America was $20 million in 1998 and is
estimated to grow to $259 million in 2001.

    While Internet use in Latin America is in a relatively early stage of
development, it has grown rapidly in recent years and, according to Nazca
Saatchi & Saatchi, is expected to significantly outpace growth in worldwide
Internet usage over the next several years. According to Audits & Surveys
Worldwide, the number of Internet users in Latin America is currently over 15
million. Nazca Saatchi & Saatchi estimates that there will be 34 million
Internet users in Latin America by the end of 2000. According to Nazca Saatchi &
Saatchi, approximately 90% of these users are from upper and middle
socio-economic classes.

    The following factors have contributed to the growth in Internet use in
Latin America:

    - increased use of personal computers, particularly among affluent Latin
      Americans;

    - network infrastructure improvements accelerated by privatization of
      telecommunications providers and increased spending;

    - govermental Internet initiatives;

    - the relative youth of the Latin American population and their tendency to
      use new technologies, like the Internet;

    - reduced Internet access costs; and

    - increased awareness of the Internet.

NEED FOR A LATIN AMERICAN ONLINE NETWORK

    Despite the rapid growth of non-English speaking Internet users worldwide,
approximately 85 to 90% of the content on the Internet remains in English,
according to Audits & Surveys Worldwide. We believe that an increasing number of
Latin American Internet users are seeking a full-service Internet offering in
their local language that provides them with:

    - a social interactive experience across the entire Spanish- and Portuguese-
      speaking world;

    - a variety of in-depth and focused local content;

    - a broad array of compelling content at the regional and international
      level;

    - fast and reliable Internet access;

    - sophisticated Internet applications and tools like e-mail, chat, instant
      messaging, bulletin boards, personal homepages and search capabilities;
      and

    - the ability to easily and securely buy goods and services online.

    To date, few Internet sites have been tailored specifically to the interests
and needs of Latin Americans. In an attempt to address this need, some of the
English language general destination sites have translated a small portion of
their content into Spanish or Portuguese. To date, however, these sites have
generally been focused on expanding into the European and Asian markets. As a
result, they typically do not extend their Spanish and Portuguese translations
beyond selected topical content and do not provide in-depth local content or
in-language applications for Latin Americans. Furthermore, they do not tailor
their translations and content to take into account regional dialects, language
differences or local cultural norms.

    Some regional sites attempt to provide content for the populations of
specific cities or countries in the local dialect. These sites, while

                                       37
<PAGE>
providing Spanish or Portuguese content, have a limited community of users and
do not provide extensive regional or global content. There are also Spanish or
Portuguese language interest-specific sites, like sports sites. These sites
offer in-depth content, but are limited to only one topic.

    We believe that few of these Spanish and Portuguese language sites attract a
broad user audience. Therefore, they cannot provide advertisers with an
attractive platform to effectively reach the highly desirable Latin American
Internet user base.

                             THE STARMEDIA SOLUTION

    We are the leading Internet media company targeting Latin America and other
Spanish- and Portuguese-speaking markets worldwide. Our network consists of
seven branded Internet properties:

    - StarMedia.com, our flagship Internet media property;

    - StarMedia Acesso, our premium Internet access service;

    - Cade?, a topical directory of Portuguese-language Web sites;

    - LatinRed, one of the largest Spanish-language online communities;

    - OpenChile, a local Chilean portal;

    - Periscopio.com, our personalized search and retrieval property; and

    - Zeek!, a topical directory of Portuguese-language Web sites.

    Through these properties, we offer our users a variety of in-language
interest-specific areas or channels, extensive Web-based community features,
sophisticated search capabilities, online shopping and Internet access services.
We believe that we have created an online network that uniquely addresses the
needs of Latin American and other Spanish- and Portuguese-speaking Internet
users and provides advertisers and merchants with a highly desirable platform
for targeting affluent consumers in our markets. Our page views have grown to
over 686 million in the three months ended June 30, 1999. In addition, our
active e-mail accounts have grown to 1.2 million as of June 30, 1999.

    We believe that our success to date is attributable to the following key
factors:

    FOCUS ON LATIN AMERICA AND OTHER SPANISH-AND PORTUGUESE-SPEAKING
MARKETS.  We serve the interests and needs of Latin American and other Spanish-
and Portuguese-speaking Internet users and have developed both a product and a
business infrastructure to support our focus on these markets. We designed our
network around the needs of our users, providing them with:

    - customized global, regional and local content covering a variety of topics
      in the appropriate Spanish and Portuguese dialect;

    - a broad range of in-language community features, like chat, bulletin
      boards, free e-mail, personal homepages, and personal and classified ads,
      that allow users to interact with each other;

    - easy-to-use interfaces and consistent navigation experiences that
      facilitate usage by the growing number of Latin Americans and other
      Spanish- and Portuguese-speaking users coming online for the first time;

    - search capabilities that can be customized by country, region and/or
      language;

    - sophisticated electronic commerce capabilities; and

    - premium Internet access service with high quality customer care and
      international account access through a single network.

    In addition, we have developed a business infrastructure designed to address
the needs of our users by maintaining a strong local presence and employing a
high percentage of Spanish- and Portuguese-speaking employees, both in the U.S.
and abroad. These employees are critical to maintaining our network's focus and
flavor.

    Our employees provide us with important cultural and linguistic insights.
Our local presence allows us to better understand the needs of local advertisers
and businesses, and to maintain strong relationships with them. Our local
offices include Barcelona, Bogota,

                                       38
<PAGE>
Buenos Aires, Caracas, Madrid, Mexico City, Montevideo, Rio de Janeiro, San
Juan, Santiago and Sao Paulo. Each office is staffed predominantly with people
from the country in which the office is located.

    MARKET LEADERSHIP THROUGH BRAND DEVELOPMENT.  We believe that StarMedia is
the most recognized Internet brand in Latin America. As a result, visiting
StarMedia is one of the first Internet experiences for many Latin Americans. We
began our marketing efforts in February 1997 and were the first online network
to make a significant investment in brand development in Latin America. We
believe that many of our regular users first visited our network in response to
our marketing efforts. We have continued to invest heavily in building the
StarMedia brands through our extensive marketing, advertising and public
relations programs. Our brand recognition has enabled us to attract a growing
user audience and leading companies as advertisers and electronic commerce
partners.

    EXTENSIVE COMMUNITY AND CONTENT OFFERINGS.  We believe that our extensive
local and pan-regional content, combined with our community of Internet users,
gives us a competitive advantage and is key to our continued leadership as the
Internet destinations of choice in the region. We provide our users with a broad
array of relevant and in-depth local content. In addition, our network serves as
a virtual central plaza for our users to access region-specific information and
conduct electronic commerce across boundaries. Our pan-regional community
enables us to attract a larger population of users and, consequently, provide
them with greater outlets for online interaction.

    DEDICATION TO USER CARE.  We believe that high quality user care and
technical support are essential to our continued success and brand development
efforts. To further enhance our users' experience and to foster user loyalty, we
have local user care support teams that rapidly respond to e-mail inquiries and
provide technical advice, 24 hours a day, seven days a week in Spanish or
Portuguese. We also proactively solicit feedback from our users in order to
understand their preferences and to enhance their experience on our network.

    HIGHLY ATTRACTIVE PLATFORM FOR ADVERTISING AND COMMERCE.  We believe that
the StarMedia network is a highly attractive platform for advertisers and
businesses because it gives them access to:

    - leading Internet brands in Latin America and other Spanish- and
      Portuguese-speaking markets;

    - a user base with a highly desirable demographic profile; and

    - users with a high degree of affinity and involvement through e-mail, chat,
      bulletin boards and personal homepages.

    Internet advertising is new in our markets, and we believe that buying
advertising on the StarMedia network is often one of the first Internet
advertising purchases made by businesses and advertising agencies targeting
Spanish- and Portuguese-speaking audiences. Accordingly, we have created an
advertising environment that fosters advertiser use of this new medium and
solidifies our relationship with advertisers. We have developed a client
services team that is dedicated to enhancing our relationship with these
advertisers and maximizing the effectiveness of their advertising campaigns. We
use our knowledge about the needs and sensitivities of our user base to help
advertisers create more effective advertising campaigns. In addition, we use
leading advertising techniques and tracking technologies to:

    - target advertising to users with specific demographic profiles;

    - gather extensive data to create an intelligence profile for each campaign;
      and

    - use daily tracking data to analyze the campaign's effectiveness.

    We provide advertisers with detailed and timely feedback on the
effectiveness of campaigns, as well as recommendations on how to improve their
campaigns. We believe that our client services group is a key differentiator
from other competitive Web sites and provides us with a significant competitive
advantage.

                                       39
<PAGE>
    As a result, we have been able to:

    - attract high-profile advertisers, including Bradesco, Ford, Fox Sports
      America, IBM, Nokia and Sony;

    - enter into relationships with leading electronic commerce companies,
      including barnesandnoble.com, CDNow, Disney, Latin Grocer and Outpost.com;
      and

    - charge premium advertising rates.

                                    STRATEGY

    Our objective is to strengthen our position as the leading online network
across Latin America and other Spanish- and Portuguese-speaking markets. In
order to accomplish this, we will:

    AGGRESSIVELY EXTEND THE RECOGNITION OF OUR BRANDS.  Our goal is to make our
brands synonymous with the Internet in our markets. We believe that continuing
to enhance our brand recognition will enable us to capitalize on our leading
position and will make us more attractive to advertisers and businesses
conducting electronic commerce. This will increase in importance as more
Spanish- and Portuguese-speaking consumers move online and as additional
Internet sites compete for these users.

    We intend to continue to build our brands through:

    - extensive television, print, Internet and outdoor advertising;

    - public relations programs;

    - conference sponsorships;

    - new strategic alliances; and

    - additional distribution relationships.

    ENHANCE AND EXPAND OUR SPANISH AND PORTUGUESE CONTENT AND COMMUNITY
FEATURES. We intend to continue to add new content and features to the StarMedia
network. We believe that this will:

    - further differentiate our brands from competing sites;

    - provide users with a more comprehensive and satisfying Internet
      experience; and

    - result in users visiting the StarMedia network more often and remaining
      there longer.

    We currently have relationships with leading content providers, including
Agencia EFE, Fox Sports America, Internet Securities, Mpath, Patagon.com,
Reuters, WeatherLabs, and Ziff-Davis. We are aggressively seeking new content
relationships in order to further increase the breadth and depth of our content
and community features without incurring significant additional costs. We
currently have more than 110 employees in our content development group who are
responsible for gathering, developing and designing our content. We intend to
further enlarge this group.

    We are also expanding our country-specific content to further penetrate
local markets. We are seeking to enter into partnerships with leading local
interest-specific content providers and to further enhance the features and
functions of our network.

    We are also seeking to aggressively expand our electronic commerce business.
We are developing relationships with credit card, fulfillment and transaction
software companies, as well as merchants. We have entered into a relationship
with SkyBox Services Corporation, a provider of logistics solutions, to
facilitate the delivery of goods sold over our network.

    FURTHERING OUR PENETRATION INTO ADDITIONAL SPANISH- AND PORTUGUESE-SPEAKING
MARKETS. We seek to make StarMedia network the first and most frequent
destination on the Internet for the Spanish- and Portuguese-speaking population
worldwide. We believe there is a significant opportunity for a Spanish and
Portuguese language online network that extends beyond Latin America to include
Spain, the United States and Portugal.

    There are approximately 8.6 million Spanish- and Portuguese-speaking
Internet users dispersed through the United States, Spain and Portugal. In the
U.S., the Hispanic population is growing more rapidly than any other minority
group. According to the Tomas Rivera Policy Institute at Claremont University,
from 1994 to 1998, Internet usage by U.S. Hispanics grew 800%. Forrester
Research Inc. estimates that by the end of 1999, 43% of U.S. Hispanic households
will be online. We believe that Hispanic Americans are increasingly using our
network to maintain their cultural identities and to communicate with friends
and family in Latin America and elsewhere.

                                       40
<PAGE>
    We have expanded our presence outside of Latin America through the
acquisition of LatinRed, which has an established user base in the Spanish and
U.S. Hispanic markets. In addition, we recently launched our Puerto Rican
operations by opening an office in San Juan to focus on advertising sales and
new business development. Additionally, we are expanding our advertising and
marketing campaigns in the United States and Spain.

    CONTINUE TO PURSUE STRATEGIC ACQUISITIONS AND ALLIANCES.  We plan to
continue to expand our user base, revenues and competitive position through
strategic acquisitions and alliances. In 1999, we made a number of strategic
acquisitions to further this goal. These include:

    - Cade?, a topical directory of Portuguese-language Web sites;

    - LatinRed, one of the largest Spanish-language online communities;

    - OpenChile, a local Chilean portal;

    - PageCell, a provider of advanced mobile technologies and services;

    - Webcast, a streaming media company focused on the global delivery of
      audio, video and other Internet-based interactive media; and

    - Zeek!, a topical directory of Portuguese-language Web sites.

We believe that these acquisitions have significantly enhanced our presence in
our markets and have enabled us to reach a broader base of users and
advertisers. We intend to aggressively seek other opportunities to acquire or
form alliances with other companies that will complement our network.

    EXPAND OUR INTERNET ACCESS SERVICES TO USERS ACROSS LATIN AMERICA.  We
recently began to offer Internet access services in Brazil and intend to offer
these services in other Latin American markets during the second half of 1999.
We believe this service will enable us to develop an additional source of
revenue and to create closer ties with Internet users in our markets. We have
entered into an agreement with AT&T Global Network Services, formerly known as
IBM Global Network. AT&T will provide us with its existing infrastructure,
billing, operations and customer service capabilities necessary to provide these
services. We will market the service under the StarMedia Acesso brand and
StarMedia will be the pre-programmed homepage for the service. We will charge
users monthly access fees with pricing based on rates that are competitive in
each local market.

    DEVELOP AND DEPLOY NEXT GENERATION CONTENT AND SERVICE DISTRIBUTION
PLATFORMS. We intend to seek opportunities to extend our brands beyond personal
computers to wireless products, consumer electronics and entertainment media. To
that end, we have created two new divisions, StarMedia Broadband and StarMedia
Mobile. StarMedia Broadband will provide Spanish- and Portuguese-speaking users
with premium streaming media services and programming, including audio, video
and interactive multimedia via the Internet. Webcast, our recent acquisition,
will serve as the core of this new division. An additional goal of StarMedia
Broadband is the enhancement of our users' interactive experience by enabling
rich media programming to be delivered quickly and efficiently via high speed
distribution platforms.

    StarMedia Mobile advances our strategy to provide our users worldwide with a
richer Internet experience by allowing them to bring Internet content and
applications to a wide range of wireless devices.

    We intend to continue to seek similar acquisition or investment
opportunities. We believe this strategy will:

    - augment our user base by enabling access to StarMedia's content and
      services by users offline;

    - enhance our brand recognition by extending our presence to new viewership;

    - increase our revenues by providing new advertising and sponsorship
      opportunities to our clients; and

    - prepare StarMedia for the future convergence of interactive and
      entertainment technologies, and further distinguish our network from
      traditional Internet portals.

    StarMedia.com's unique design and layout provides a consistent navigation
experience allowing users to access any channel on StarMedia.com from any other
channel on the service. Additionally, this design allows for persistent

StarMedia Acesso is designed to offer Latin Americans fast, reliable Internet

    We have contracted with AT&T Global Network Services, formerly the IBM

infrastructure, operational, billing, and customer service capabilities.

    We have begun to offer access services through Acesso in Brazil and intend
to expand our Internet access services in other Latin American markets during

                              STRATEGIC ALLIANCES

    We have developed strategic relationships with leading content, electronic
commerce, syndication and application partners. Many of these relationships give
us various exclusive rights. For example, some of these partners have agreed
that StarMedia properties will be the only Internet companies to display their
content in Spanish or Portuguese. Others have agreed that they will not enter
into agreements with other companies targeting the Spanish or Portuguese
Internet markets. These relationships are typically for a period of one to five
years.

    These relationships are designed to:

    - enhance our network;

    - expand our community of users;

    - increase traffic; and

    - provide us with additional revenues.

    Our partners allow us to display their content or technology on our network,
within one or many of our channels, in exchange for a share of revenue or a
licensing fee. We receive some of this content in a format that is ready to
publish on our network. We also receive content that we must modify in order to
publish. For example, some of our partners provide us with English-language
content. In these cases, we translate the content into Spanish and Portuguese
prior to publishing it on our network.

    Our commerce partners typically pay us a flat fee for placement on our
network. This fee is based on location of links that allow for entry into their
online store and the number of links present throughout our network. These
partners also share with us a percentage of transaction revenues generated when
our users purchase their products or services.

both Spanish and Portuguese. NETSCAPE GUIDE BY STARMEDIA is one of the core
services available as part of Netscape's Latin American Spanish and Portuguese
browsers. We also appear as a premium bookmark located on Netscape's Spanish and
Portuguese browser toolbars. These bookmarks link users directly to
StarMedia.com. StarMedia Noticias/Noticias appears as a ticker on the Netscape
Latin America and Brazil homepages and directs users to our news areas. In
addition, Netscape promotes StarMedia throughout its Spanish and Portuguese
offerings.

REALNETWORKS

    In February 1999, we entered into a relationship with RealNetworks, the
leading provider of streaming audio/video over the Internet. StarMedia.com is
the only in-language Internet destination featured as a default channel on both
the Spanish and Portuguese versions of RealNetworks' RealPlayer G2. This
relationship uniquely positions us to enhance our user base by enabling Spanish
and Portuguese-speaking Internet users to access our in-language streaming
content, including music videos, television and radio programming, and sporting
events directly from RealPlayer.

SKYBOX

    We have entered into an exclusive distribution relationship with SkyBox
Services Corporation, a provider of logistics solutions for electronic commerce
clients and U.S. merchandisers targeting Latin America. Through our relationship
with SkyBox, we provide our Latin American users with the ability to make
purchases with an ease of transaction similar to that available to those living
in the U.S. As part of the StarMedia/ SkyBox service, non-U.S. resident clients
are provided with a U.S. suite address at which SkyBox receives correspondence
and

                                       45
<PAGE>
merchandise, and from which it then forwards these items to the clients' home or
office. SkyBox systems handle the receipt of merchandise, the international
transportation, customs clearance and home delivery, all at very competitive
rates.

RECENT STRATEGIC INVESTORS

    In April and May 1999, we completed the private placement of 3,727,272
shares of our common stock to a number of strategic investors for $41 million.
These investors include:

    - Critical Path, Inc.;

    - eBay Inc.;

    - Europortal Holding S.A.;

    - Hearst Communications, Inc.;

    - National Broadcasting Company, Inc.; and

    - Reuters Holdings Switzerland SA.

    We intend to continue to work closely with our strategic investors in order
to develop new content and to add new features to our network.

                              RECENT ACQUISITIONS

    We have made a number of acquisitions in order to further expand the breadth
of the services we provide to Latin American and other Spanish- and
Portuguese-speaking Internet users.

WEBCAST SOLUTIONS

    We acquired Webcast as the foundation of our StarMedia Broadband division,
which will allow us to develop and deploy next generation content and service
distribution platforms. Webcast is a streaming media company focused on the
global delivery of audio, video and other Internet-based interactive media.
Webcast combines the latest streaming media technologies with expert on-location
media production, Web site design, content hosting, media management and online
promotion for use in dynamic, media rich Web sites and broadband applications.
Webcast has accumulated significant expertise in the deployment of international
webcasting and on-site production, particularly in Latin America.

PAGECELL

    In September 1999, we purchased substantially all of the assets of PageCell.
PageCell is a provider of advanced mobile technologies and services. It brings
Internet content and applications to wireless devices such as pagers and cell
phones. PageCell's key offerings include its mobile software technologies,
including its mobile Internet platforms, wireless portal services and messaging
services. Through these technologies, we are able to deliver content and
features such as e-mail, weather, horoscopes, sports, finance and other
personalized information to wireless devices including pagers, cellular phones
and personal digital assistants. PageCell serves as the core of our new
division, StarMedia Mobile.

                               ADVERTISING SALES

    We have built a direct sales organization of 99 professionals located in
Bogota, Buenos Aires, Caracas, Dallas, Los Angeles, Madrid, Mexico City, Miami,
New York, Rio de Janeiro, San Juan, Santiago and Sao Paulo.

SALES ORGANIZATION

    Our sales organization is dedicated to maintaining close relationships with
top advertisers and leading advertising agencies throughout our target markets.
It is structured on a regional basis and is focused solely on selling
advertising on our network. Our sales organization consults regularly with
advertisers and agencies on design and placement of their Web-based advertising,
provides customers with advertising measurement analysis and focuses on
providing a high level of customer service satisfaction.

ADVERTISING PROGRAMS

    Currently, advertisers and advertising agencies enter into agreements under
which they pay for a guaranteed number of impressions for a fixed fee. These
agreements

                                       46
<PAGE>
range from one month to multiple years. Advertising on our network currently
consists primarily of banner-style advertisements, buttons and sponsorships from
which viewers can hyperlink directly to the advertiser's own Web site. Our
standard cost per thousand impressions, commonly referred to as CPMs, for banner
advertisements varies depending on location of the advertisements on the
network, the targeted country and the extent to which advertisements are
targeted for a particular audience. Discounts from standard CPM rates may be
provided for higher volume, longer-term advertising contracts.

    We also offer promotional advertising programs, such as contests, sampling
and couponing opportunities, in order to build brand awareness, generate leads
and drive traffic to an advertiser's site.

ADVERTISING CUSTOMERS

    We had 160 advertisers and sponsors on our network during the three months
ended June 30, 1999. The following is a selected list of our current advertising
customers, which are representative of our customer base:

<TABLE>
<S>                    <C>
Banco Santander        Nokia
Bradesco               Outpost.com
Ford                   SkyTel
Fox Sports America     Sony
IBM                    USA Networks
</TABLE>

    These customers, in the aggregate, accounted for approximately 20% of total
revenues in the three months ended June 30, 1999 and 33% of total revenues for
the year ended December 31, 1998.

    We have derived substantially all of our revenues to date from the sale of
advertisements and sponsorships. In the six months ended June 30, 1999, no
advertiser accounted for greater than 10% of total revenues. During the same
period, our five largest advertisers accounted for 33% of total revenues. In
1998, two advertisers, Fox Sports America and Netscape, each accounted for
greater than 10% of total revenues. During the same period, our five largest
advertisers accounted for 57% of total revenues.

                         MARKETING AND BRAND AWARENESS

    We use multiple advertising media, like television, print and Web-based
advertising in order to:

    - build our brand;

    - increase traffic; and

    - raise our profile among potential advertisers.

    Our television advertisements have appeared on broadcast television in
Brazil, Mexico, Colombia, Argentina, Chile, the United States, Uruguay,
Venezuela, Spain, Peru and on cable networks throughout Latin America. Our first
television commercial, "Birth of a Star", began airing in 18 Latin American
markets in Spanish and Portuguese in February 1997. In addition to advertising
on television, we advertise in print, use outdoor advertising and have a
significant presence in highly-targeted online media. We also have an extensive
public relations campaign. We are currently in the midst of our fourth
advertising campaign across Latin America. Our strategic and content partners
also typically provide us with advertising support.

    We form marketing alliances with companies that have broad reach and whose
customers are similar to our target customers. We currently have co-marketing
relationships with Fox Sports America and MTV Latin America and regional
television stations.

                           TECHNOLOGY INFRASTRUCTURE

    Our technology infrastructure is built and maintained for reliability,
security, and flexibility and is administered by our technical staff.

    We maintain our central production servers at the New Jersey data center of
Exodus Communications. We maintain regional network operating centers in Brazil
and Argentina. Our operations depend on the ability of Exodus to protect its
systems against damage from fire, hurricanes, power loss, telecommunications
failure, break-ins, or other events.

    Exodus provides comprehensive facilities management services, including
human and

                                       47
<PAGE>
technical monitoring of all production servers 24 hours per day, 7 days per
week. Exodus also provides connectivity for our U.S. servers through multiple
high-speed connections. In Brazil and Argentina, our servers are connected to
the largest Internet service providers in each country. All facilities are
protected by multiple uninterruptible power supplies.

    For reliability, availability, and serviceability, we have implemented an
environment in which each server can function separately. Key components of our
server architecture are served by multiple redundant machines.

    We employ in-house and third-party monitoring software. Reporting and
tracking systems generate daily traffic, demographic, and advertising reports.
Our production data is copied to backup tapes each night.

    We employ in-house and third-party software to monitor access to our
production and development servers.

    Our network 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. These events did not have a material adverse effect on our
business.

                LATIN AMERICAN TELECOMMUNICATION INFRASTRUCTURE

    Many of the largest markets in Latin America, including Argentina, Brazil,
Chile, Colombia and Mexico, have privatized and begun to deregulate their
telephone industries. As a result, many Latin American telephone companies in
recent years have undertaken significant investments in their infrastructure.
These investments have resulted in an improvement in the quality of telephone
service in these countries. In addition, deregulation has had a direct impact on
the cost and quality of Internet access as competition has driven down both
monthly access fees and per minute usage charges.

    In the past, Internet service providers, or ISPs, in Latin America charged
an average of more than $80 per month for basic Internet access. Today, monthly
Internet access fees have decreased to an average of $20 to $25 per month. In
addition to access charges, local calls to connect to the ISP range in cost from
$.02-$.05 per minute in some countries, including Venezuela, Peru, Argentina,
Chile and Brazil and up to $.12 per minute in Mexico. These per minute charges
may make the total cost of Internet access substantially greater in Latin
America than in the United States, where users typically only pay a monthly
access fee and nominal local charges, if any. Long distance charges, if
required, would make the total cost of Internet access in Latin America even
greater.

    While per minute charges have not declined as rapidly as access costs, we
believe that they will trend downward as the effects of deregulation spread.
Because our target market consists of a relatively affluent part of the
population across Latin America, we do not believe that Internet access costs
are a significant deterrent for many of our users. However, if rates were to
increase substantially or fail to decline in the future, the number of visitors
to our network may decline or fail to grow.

    The majority of Latin Americans access the Internet via traditional analog
dial-up accounts. Digital access is still relatively expensive and is not widely
available throughout Latin America. We do not believe that the quality of
telephone service has to date been a deterrent to the number of users that visit
our network.

                                  COMPETITION

    There are many companies that provide Web sites and online destinations
targeted to Latin Americans and Spanish- and Portuguese-speaking people in
general. All of these companies compete with us for visitor traffic, advertising
dollars and electronic commerce partners. The market for Internet content
companies in Latin America is new and rapidly evolving. Competition for
visitors, advertisers and electronic commerce partners is intense

                                       48
<PAGE>
and is expected to increase significantly in the future because there are no
substantial barriers to entry in our market. Increased competition could result
in:

    - lower advertising rates;

    - price reductions and lower profit margins;

    - loss of visitors;

    - reduced page views; or

    - loss of market share.

Any one of these could materially and adversely affect our business, financial
condition and results of operations.

    Our ability to compete successfully depends on many factors. These factors
include:

    - the quality of the content provided by us and our competitors;

    - how easy our respective services are to use;

    - sales and marketing efforts; and

    - the performance of our technology.

    We compete with providers of Spanish-and Portuguese-language content and
services over the Internet, including Web directories, search engines, content
sites, Internet service providers and sites maintained by government and
educational institutions. Our current and anticipated competitors include:

    - America Online;

    - Telefonica Interactiva;

    - Telefonos de Mexico/Prodigy;

    - Universo Online; and

    - Yahoo! en espanol/Yahoo! Brasil.

    Many of our competitors and potential new competitors have:

    - longer operating histories;

    - greater name recognition in some markets;

    - larger customer bases; and

    - significantly greater financial, technical and marketing resources.

    These competitors may also be able to:

    - undertake more extensive marketing campaigns for their brands and
      services;

    - adopt more aggressive advertising pricing policies;

    - use superior technology platforms to deliver their products and services;
      and

    - make more attractive offers to potential employees, distribution partners,
      commerce companies, advertisers and third-party content providers.

    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. This could have a material and
adverse effect on our business, financial condition and results of operations.

    We also compete with traditional forms of media, like newspapers, magazines,
radio and television 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.

                 GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES

    To date, regulations have not materially restricted use of the Internet in
our markets. However, the legal and regulatory environment that pertains to the
Internet is uncertain and may change. New laws and regulations may be adopted.
Existing laws may be applied to the Internet and new forms of electronic
commerce. Uncertainty and new regulations could increase our costs and prevent
us from delivering our products and services over the Internet. It could also
slow the growth of the Internet significantly. This could delay growth in demand
for our network and limit the growth of our revenues. New and existing laws may
cover issues like:

                                       49
<PAGE>
    - 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;

    - pornography; and

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

                  INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

    We regard our copyrights, service marks, trademarks, trade secrets and other
intellectual property as critical to our success. We rely on trademark and
copyright law, trade secret protection and confidentiality and/or license
agreements with our employees, customers, partners and others to protect our
intellectual property rights. Despite our precautions, it may be possible for
third parties to obtain and use our intellectual property without authorization.
Furthermore, the validity, enforceability and scope of protection of
intellectual property in Internet-related industries is uncertain and still
evolving. The laws of some foreign countries do not protect intellectual
property to the same extent as do the laws of the United States.

    We pursue the registration of our trademarks in the United States and
internationally in Latin America, Spain and Portugal. We may not be able to
secure adequate protection for our trademarks in the United States and other
countries. [An action has been filed in Chile opposing our STARMEDIA and design
mark, which we are currently contesting.] In addition, there have been
oppositions filed against our applications in other countries for some of our
other marks.

    We currently hold service mark or trademark registrations in the United
States, Peru, Uruguay, Colombia and Paraguay for the StarMedia mark and
registrations for other marks in some of these and other countries. Effective
trademark protection may not be available in all the countries in which we
conduct business. Policing unauthorized use of our marks is also difficult and
expensive. In addition, it is possible that our competitors will adopt product
or service names similar to ours, thereby impeding our ability to build brand
identity and possibly leading to customer confusion.

    We actively seek to protect our marks against similar and confusing marks of
third parties by:

    - using a watch service which identifies applications to register
      trademarks;

    - filing oppositions to third parties' applications for trademarks; and

    - bringing lawsuits against infringers.

    For example, we were aware of an unauthorized use of our PIZARRAS trademark
and successfully pursued enforcement of our rights against that party. Similar
actions like this may be time consuming and expensive. Our inability to
effectively protect our trademarks and service marks would have a material
adverse effect on our business, financial condition and results of operations.

    Many parties are actively developing chat, homepage, search and related Web
technologies. We expect these developers to continue to take steps to protect
these technologies, including seeking patent protection. There may be patents
issued or pending that are held by others and that cover significant parts of
our technology, business methods or services. For example, we are aware that a
number of patents have been issued in the areas of electronic commerce,
Web-based information indexing and retrieval and online direct marketing.
Disputes over rights to these technologies are likely to arise in the future. We
cannot be certain that our products do not or will not infringe valid patents,
copyrights or other intellectual property rights held by third parties. We may
be subject to legal proceedings and claims from time to time relating to the
intellectual property of others in the ordinary course of our

                                       50
<PAGE>
business. In the event that we determine that licensing this intellectual
property is appropriate, we may not be able to obtain a license on reasonable
terms or at all. We may also incur substantial expenses in defending against
third-party infringement claims, regardless of the merit of these claims.
Successful infringement claims against us may result in substantial monetary
liability or may prevent us from conducting all or a part of our business.

    We also intend to continue to license technology from third parties,
including our Web-server and encryption technology. The market is evolving and
we may need to license additional technologies to remain competitive. We may not
be able to license these technologies on commercially reasonable terms or at
all. In addition, we may fail to successfully integrate any licensed technology
into our services. Our inability to obtain any of these licenses could delay
product and service development until alternative technologies can be
identified, licensed and integrated.

                                   EMPLOYEES

    As of June 30, 1999, we had 409 full-time employees, of whom 99 worked in
sales, 10 in editorial, 24 in marketing, 203 in product and technology and 73 in
finance and administration. From time to time, we employ independent contractors
to support our research and development, marketing, sales and editorial
departments. None of our personnel are represented under collective bargaining
agreements. We consider our relations with our employees to be good.

                                   FACILITIES

    Our principal executive offices are located in approximately 19,500 square
feet of office space in New York, New York, under a lease that expires in August
2003. We also lease sales and business development office space in:

    - Barcelona, Spain;

    - Bogota, Colombia;

    - Buenos Aires, Argentina;

    - Caracas, Venezuela;

    - Madrid, Spain;

    - Mexico City, Mexico;

    - Miami, Florida;

    - Montevideo, Uruguay;

    - Rio de Janeiro, Brazil;

    - San Francisco, California;

    - San Juan, Puerto Rico;

    - Santiago, Chile; and

    - Sao Paulo, Brazil.

                               LEGAL PROCEEDINGS

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

                         CLASSIFIED BOARD OF DIRECTORS

    Our board of directors is divided into three classes of directors serving
staggered three-year terms. Upon expiration of the term of a class of directors,
the directors in that class will be elected for three-year terms at the annual
meeting of stockholders in the year in which their term expires. Our board of
directors has resolved that Messrs. Chen and Karp will be Class I directors
whose terms expire at the 2000 annual meeting of stockholders, Messrs. Linen and
Wilson will be Class II directors whose terms expire at the 2001 annual meeting
of stockholders, and Messrs. Espuelas and Rosenkranz and Ms. Segal will be Class
III directors whose terms expire at the 2002 annual meeting of stockholders.
With respect to each class, a director's term will be subject to the election
and qualification of their successors, or their earlier death, resignation or
removal. In addition, our directors may be removed only for cause and only by
the affirmative vote of holders of not less than 66.67% of our outstanding
capital stock entitled to vote generally in the election of directors. These
provisions, when coupled with the provision of our amended and restated
certificate of incorporation authorizing the board of directors to fill vacant
directorships, may delay a stockholder from removing incumbent directors and
simultaneously gaining control of the board of directors by filling the
vacancies with its own nominees.

                                BOARD COMMITTEES

    The audit committee reports to the board regarding the appointment of our
independent public accountants, the scope and results of our annual audits,
compliance with our accounting and financial policies and management's
procedures and policies relative

                                       54
<PAGE>
to the adequacy of our internal accounting controls. The audit committee
consists of Gerardo M. Rosenkranz and Frederick R. Wilson.

    The compensation committee of the board of directors reviews and makes
recommendations to the board regarding our compensation policies and all forms
of compensation to be provided to our executive officers and directors. In
addition, the compensation committee reviews bonus and stock compensation
arrangements for all of our other employees. The current members of the
compensation committee are Christopher T. Linen and Frederick R. Wilson. No
interlocking relationships exist between our board of directors or compensation
committee and the board of directors or compensation committee of any other
company, nor has any interlocking relationship existed in the past.

                             DIRECTOR COMPENSATION

    Directors currently do not receive a stated salary from StarMedia for their
service as members of the board of directors, although by resolution of the
board, they may receive a fixed sum and reimbursement for expenses in connection
with the attendance at board and committee meetings. We currently do not provide
additional compensation for committee participation or special assignments of
the board of directors. From time to time, some of our directors have received
grants of options to purchase shares of common stock.

                             EXECUTIVE COMPENSATION

the year ended December 31, 1998 to our Chief Executive Officer and to each of

                       OPTION GRANTS IN LAST FISCAL YEAR

    The following table sets forth grants of stock options for the year ended
December 31, 1998 to our Chief Executive Officer and our most highly compensated
executive officers, other than our Chief Executive Officer, whose salary and
bonus exceeded $100,000. The options shown for each executive officer do not
include options cancelled under our 1997 Plan, but do include the immediate
reissuance of options equal to the cancelled options under our 1998 Plan. We
have never granted any stock appreciation rights. The potential

                                       55
<PAGE>
realizable value is calculated based on the term of the option at its time of
grant. It is calculated assuming that the fair market value of common stock on
the date of grant appreciates at the indicated annual rate compounded annually
for the entire term of the option and that the option is exercised and sold on
the last day of its term for the appreciated stock price. These numbers are
calculated based on the requirements of the Securities and Exchange Commission
and do not reflect our estimate of future stock price growth. The percentage of
total options granted to employees in the last fiscal year is based on options
to purchase an aggregate of 5,782,000 shares of common stock granted under our
1998 Plan to our employees, consultants and directors and under our 1997 Plan to
Messrs. Espuelas and Chen in the year ended December 31, 1998. All options
granted under our 1997 Plan, other than those granted to Messrs. Espuelas and
Chen, have been cancelled and reissued under our 1998 Plan.

    The following table provides some information about stock options held as of
December 31, 1998 by our Chief Executive Officer and our most highly compensated
executive officers other than our Chief Executive Officer. No options were
exercised during fiscal 1998 by any of these executive officers. There was no
public trading market for the common stock as of December 31, 1998. Accordingly,
the value of unexercised in-the-money options at fiscal year-end is based on
$15.00 per share, less the exercise price per share, multiplied by the number of
shares underlying the options.

                              EMPLOYMENT CONTRACTS

    We have entered into executive employment agreements with Fernando J.
Espuelas, our Chairman and Chief Executive Officer, and Jack C. Chen, our
President. Each employment agreement provides for an initial annual base salary
of $150,000 that will be automatically increased effective each January 1 by not
less than 10% of the previous year's base salary. Each employment agreement also
provides for an initial annual bonus of not less than $100,000, that will also
be increased annually by not less than 10% of the previous year's bonus amount.
Each executive is also entitled to participate in our
stock option plans as well as all health, welfare and other benefit plans
provided by us to key executive employees.

    Each employment agreement expires on July 31, 2000, subject to earlier
termination or extension. Each employment agreement provides that, if Messrs.
Espuelas or Chen is terminated by us without cause, or if they choose to
terminate their employment with us for good reason, they will be entitled to
receive from us:

    - their base salary through the termination date;

    - any accrued but unpaid vacation pay;

    - the amount of all compensation previously deferred, if any, together with
      any accrued interest or earnings on any deferred compensation;

    - a termination payment of 200% of the annual base salary and guaranteed
      minimum bonus amount applicable to the year in which the termination
      occurs; and

    - health and disability benefits for twenty-four months following the
      termination date.

    Under the agreements, good reason includes:

    - a material breach of the compensation provisions of the employment
      agreements;

    - assignment of Messrs. Espuelas or Chen to duties that are inconsistent
      with their roles as executive officers;

    - relocation of Messrs. Espuelas or Chen outside of the New York
      metropolitan area;

    - a change of the reporting relationship of Messrs. Espuelas or Chen; or

    - a change of control.

    In addition, in the event Messrs. Espuelas or Chen is terminated by us
without cause, or if they choose to terminate their employment with us for good
reason, all stock options previously granted to them that have not been
exercised and are outstanding will remain outstanding and continue to become
exercisable pursuant to their respective terms.

    Each employment agreement prohibits Messrs. Espuelas and Chen from competing
with us for a period of two years from the date of their termination of
employment, if they are terminated either by us for cause or if they choose to
terminate their employment with us without good reason. If we terminate their
employment without cause, the non-compete period lasts for one year from the
date of termination.

    We have agreed to indemnify Messrs. Espuelas and Chen for all liabilities
relating to their status as officers or directors, and any actions committed or
omitted by them in this capacity, to the maximum extent permitted by the laws of
the State of Delaware.

                               STOCK OPTION PLANS

1997 STOCK OPTION PLAN

    Our 1997 Stock Option Plan was adopted by the board of directors in June
1997. A total of 5,000,000 shares of common stock were authorized for issuance
under the 1997 Plan. When the 1998 Plan was adopted, all options outstanding
under the 1997 Plan were cancelled and reissued under the 1998 Plan, other than
those granted to Messrs. Espuelas and Chen in the aggregate amount of 2,000,000.
We will not issue additional options under the 1997 Plan.

                                       57
<PAGE>
    The exercise price for the shares of common stock subject to option grants
made under the 1997 Plan may, at the discretion of the plan administrator, be
paid in cash or in shares of common stock valued at fair market value on the
exercise date.

    In the event of a merger pursuant to which StarMedia is acquired, each
outstanding option may, at the discretion of the plan administrator, be assumed
by the successor corporation or terminated in exchange for a cash payment equal
to the difference between the fair market value of the shares for which the
option is at the time exercisable and the exercise price payable for such
shares.

    The board may amend or modify the 1997 Plan at any time. The 1997 Plan will
terminate in all events on December 31, 1999. Options under the 1997 Plan,
however, will remain outstanding in accordance with their terms.

1998 STOCK PLAN

    Our 1998 Stock Plan was adopted by the board of directors and approved by
the stockholders in July 1998. A total of 17,000,000 shares of common stock have
been authorized for issuance under the 1998 Plan. The number of shares of common
stock available for issuance under the 1998 Plan will increase on July 1 of each
year beginning in 2000 by the lesser of:

    - 4 million shares;

    - 4% of the outstanding shares on such date; or

    - an amount determined by the board.

    Under the 1998 Plan, eligible individuals in StarMedia's employ or service
may, at the discretion of the plan administrator, be granted options to purchase
shares of common stock at an exercise price determined by the plan administrator
or may be issued shares of common stock directly through the purchase of such
shares at a price determined by the plan administrator. Eligible individuals
include officers, non-employee board members and consultants.

    The 1998 Plan is administered by the compensation committee of the board.
The compensation committee as plan administrator has complete discretion to
determine which eligible individuals are to receive option grants or stock
issuances, the time or times when option grants or stock issuances are to be
made, the number of shares subject to each grant or issuance, the status of any
granted option as either an incentive stock option or a non-statutory stock
option under the Federal tax laws, the vesting schedule to be in effect for the
option grant or stock issuance and the maximum term for which any granted option
is to remain outstanding.

    The exercise price for the shares of common stock subject to option grants
made under the 1998 Plan may, at the discretion of the plan administrator, be
paid in cash, in shares of common stock valued at fair market value on the
exercise date, through a same-day sale program without any cash outlay by the
optionee or by delivering a full-recourse, interest-bearing promissory note.

    In the event of an acquisition of StarMedia, whether by merger or asset
sale, each option which is not to be assumed by the successor corporation will
automatically accelerate in full and all unvested shares will immediately vest,
except to the extent that StarMedia's repurchase rights with respect to those
shares are to be assigned to the successor corporation.

    The plan administrator has the authority to effect the cancellation of
outstanding options in return for the grant of new options for the same or
different number of option shares with an exercise price per share based upon
the fair market value of the common stock on the new grant date.

    The board may amend or modify the 1998 Plan at any time, subject to any
required stockholder approval. The 1998 Plan will terminate on the earliest of:

    - the date determined by the board;

    - the date on which all shares available for issuance under the 1998 Plan
      have been issued as fully-vested shares; or

                                       58
<PAGE>
    - the termination of all outstanding options in connection with an
      acquisition of StarMedia.

1999 EMPLOYEE STOCK PURCHASE PLAN

    Our 1999 Employee Stock Purchase Plan was adopted by the Board of Directors
in May 1999. A total of 1,500,000 shares of common stock has been reserved for
issuance under the purchase plan, plus annual increases, on July 1 of each year
beginning in 2000, equal to the lesser of:

    - 500,000 shares;

    - 1% of the outstanding shares on such date; or

    - a lesser amount determined by the Board.

    The purchase plan is intended to qualify under Section 423 of the Internal
Revenue Code of 1986, as amended. It contains successive, overlapping 24-month
offering periods, each consisting of four six-month purchase periods. The
offering periods generally start on the first trading day on or after May 15 and
November 15 of each year, except for the first offering period which commences
on the first trading day on or after the effective date of this offering and
ends on the last trading day on or before May 14, 2001.

    Our employees are eligible to participate in the stock plan if they work
with StarMedia for at least 20 hours per week and more than five months in any
calendar year. However, any employee who:

    - immediately after grant owns stock representing 5% or more of the total
      combined voting power or value of all classes of our capital stock, or

    - whose rights to purchase stock under all of our employee stock purchase
      plans exceed $25,000 worth of stock for any calendar year

may not be granted any rights to purchase stock under the purchase plan. The
purchase plan permits participants to purchase common stock through payroll
deductions of not less than 2% and up to 10% of their "cash earnings". Cash
earnings is defined as the participant's base salary plus all overtime payments,
bonuses, commissions, current profit sharing distributions and other incentive-
type payments. Cash earnings are calculated before the deduction of any income
or employment tax withholdings or any pre-tax contributions made by the
participant to a 401(k) plan or cafeteria benefit program. The maximum number of
shares a participant may purchase during a single purchase period is 2,500
shares.

    Amounts deducted and accumulated by the participant are used to purchase
shares of common stock at the end of each offering period. The price of stock
purchased under the purchase plan is 85% of the lower of the fair market value
of the common stock at the beginning or end of the offering period. Participants
may end their participation at any time during an offering period, and they will
be paid their payroll deductions to date. Participation ends automatically upon
termination of a participant's employment.

    Rights granted under the purchase plan are not transferable by a participant
other than by will, the laws of descent and distribution, or as otherwise
provided under the purchase plan. The purchase plan provides that, in the event
that we merge with or into another corporation or sell substantially all of our
assets, each outstanding right to purchase stock will be assumed or substituted
for by the successor corporation. If the successor corporation refuses to assume
or substitute for the outstanding rights to purchase stock, the offering period
then in progress will be shortened and a new exercise date will be set. The
purchase plan will terminate in 2009. The Board has the authority to amend or
terminate the purchase plan, except that, subject to certain exceptions, no such
action may adversely affect any outstanding rights to purchase stock under the
purchase plan.

                          DESCRIPTION OF CAPITAL STOCK

                                    GENERAL

    StarMedia's amended and restated certificate of incorporation authorizes the
issuance of up to 200,000,000 shares of common stock, par value $.001 per share,
and 10,000,000 shares of preferred stock, par value $.001 per share, the rights
and preferences of which may be established from time to time by StarMedia's
board of directors. As of June 30, 1999, 58,006,198 shares of common stock were
outstanding and no shares of preferred stock were outstanding. As of June 30,
1999, StarMedia had 162 stockholders of record.

                                  COMMON STOCK

    Under our amended and restated certificate of incorporation, holders of our
common stock are entitled to one vote for each share held of record on all
matters submitted to a vote of the stockholders, including the election of
directors. They do not have cumulative voting rights. Subject to preferences
that may be applicable to any then-outstanding preferred stock, holders of our
common stock are entitled to receive ratably dividends, if any, as may be
declared by the board of directors out of legally available funds. In case of a
liquidation, dissolution or winding up of StarMedia, the holders of common stock
will be entitled to share ratably in the net assets legally available for
distribution to shareholders after payment of all of our liabilities and any
preferred stock then outstanding. Holders of common stock have no preemptive or
conversion rights or other subscription rights. There are no redemption or
sinking fund provisions applicable to the common stock. The rights, preferences
and privileges of holders of common stock are subject to the rights of the
holders of shares of any series of preferred stock that we may designate and
issue in the future.

                                PREFERRED STOCK

    Under our amended and restated certificate of incorporation, our board of
directors has the authority, without further action by the stockholders, to
issue from time to time, shares of preferred stock in one or more series. The
board of directors may fix the number of shares, designations, preferences,
powers and other special rights of the preferred stock. The preferences, powers,
rights and restrictions of different series of preferred stock may differ. The
issuance of preferred stock could decrease the amount of earnings and assets
available for distribution to holders of common stock or affect adversely the
rights and powers, including voting rights, of the holders of common stock. The
issuance may also have the effect of delaying, deferring or preventing a change
in control of StarMedia.

    Our board of directors has authorized the issuance of shares of junior
non-voting convertible preferred stock in connection with our acquisition of
PageCell, of which 58,140 shares are issued and outstanding. Holders of our
junior non-voting convertible preferred stock rank junior or PARI PASSU to any
other series of our preferred stock that we may subsequently issue in terms of
distribution of assets upon the liquidation, dissolution or winding up of our
company and the payment of dividends.

    If and when we pay a dividend on our common stock, the holders of our junior
non-voting convertible preferred stock will be entitled to receive a dividend
equal to the amount they would have received if their shares had been converted
into shares of common stock immediately prior to the record date for the
dividend. Also, in the event of the liquidation, dissolution or winding up of
our company, the holders of the preferred stock will receive, before the payment
or distribution of our assets to the holders of our common stock, a payment or
distribution equal to the amount the holders would have received if their shares
were converted into shares of common stock.

    The holders of the junior non-voting convertible preferred stock are not
entitled to vote on any matter to be voted upon by our stockholders, except as
required by Delaware law. After the first anniversary of the issuance of the
junior non-voting convertible preferred

                                       64
<PAGE>
stock, the holders of the junior non-voting convertible preferred stock will be
entitled to convert all of their shares into shares of our common stock at a
one-to-one conversion rate.

                              REGISTRATION RIGHTS

    Under the terms of our amended and restated registration rights agreement,
at any time on or after June 1, 2000, each of Chase Venture Capital Associates,
Warburg, Pincus Equity Partners and the holders of a majority of the outstanding
shares of common stock held by parties to that agreement may, on one occasion
only, require us to register for sale all or any portion of the shares of common
stock held by them. We are also obligated to register any of the shares of
common stock held by parties to the registration rights agreement if they
request to be included in the registration. These parties, in the aggregate,
have three demand registration rights. Further, if we become eligible to file
registration statements on Form S-3, a holder of our common stock which is a
party to the registration rights agreement may require us to file a registration
statement on Form S-3 under the Securities Act with respect to their shares of
common stock. We are also obligated to register the shares of common stock held
by parties to the registration rights agreement if they request to be included
in the registration, provided that we will not be required to effect any Form
S-3 registration more than once in any 180-day period. In addition, holders of
common stock which are parties to the registration rights agreement will be
entitled to require us to register the common stock when we register stock for
our own account or the account of other stockholders. This type of registration
right is known as a "piggyback" registration right. Mr. Espuelas and Mr. Chen
may also participate in any demand, S-3 or piggyback registration.

    The foregoing registration rights are subject to certain conditions and
limitations, including:

    - the right of the underwriters in any underwritten offering to limit the
      number of shares of common stock held by stockholders with registration
      rights to be included in any demand, S-3 or piggyback registration; and

    - our right to delay for up to 90 days the filing or effectiveness of a
      registration statement pursuant to a demand for registration if the board
      of directors of determines that the registration would not be in our best
      interest at that time.

    We are generally required to bear all of the expenses of all registrations,
except underwriting discounts and commissions. Registration of any of the shares
of common stock held by stockholders with registration rights would result in
those shares becoming freely tradable without restriction under the Securities
Act immediately after effectiveness of the registration. We have agreed to
indemnify the holders of registration rights in connection with demand, S-3 and
piggyback registration under the terms of our amended and restated registration
rights agreement.

    In connection with our private placement of an aggregate of 3,727,272 shares
of common stock in May 1999, we granted the investors registration rights. As a
result, each of the investors may require us to register the shares of common
stock they purchased. If at any time between the first and third anniversary of
the private placement we propose to register any of our common stock, we have
agreed, upon their written request, to include the investors' shares of common
stock in the registration. The number of shares of common stock which we will be
required to register for the investors may be reduced in an underwritten
offering by the managing underwriter.

    We are generally required to bear all of the expenses of registering the
investors' shares of common stock, other than underwriting discounts and
commissions. Registration of any of the shares of common stock held by the
investors would result in those shares becoming freely tradable without
restriction under the Securities Act immediately after effectiveness of the
registration. We have agreed to indemnify the investors in connection with the
registration of their shares of common stock under the terms of the registration
rights agreements.

 ANTI-TAKEOVER EFFECTS OF DELAWARE LAW AND OUR AMENDED AND RESTATED CERTIFICATE
                          OF INCORPORATION AND BYLAWS

    Provisions of our amended and restated certificate of incorporation and
amended and restated bylaws, which are summarized in the following paragraphs,
may be deemed to have an anti-takeover effect and may delay, defer or prevent a
tender offer or takeover attempt that a stockholder might consider it its best
interest, including those attempts that might result in a premium over the
market price for the shares held by stockholders.

CLASSIFIED BOARD OF DIRECTORS

    Our board of directors is divided into three classes of directors serving
staggered three-year terms. Upon expiration of the term of a class of directors,
the directors in that class will be elected for three-year terms at the annual
meeting of stockholders in the year in which their term expires. Our board of
directors has resolved that Messrs. Chen and Karp will be Class I directors
whose terms expire at the 2000 annual meeting of stockholders, Messrs. Linen and
Wilson will be Class II directors whose terms expire at the 2001 annual meeting
of stockholders, and Messrs. Espuelas and Rosenkranz and Ms. Segal will be Class
III directors whose terms expire at the 2002 annual meeting of stockholders.
With respect to each class, a director's term will be subject to the election
and qualification of their successors, or their earlier death, resignation or
removal. In addition, our board of directors may be removed only for cause and
only by the affirmative vote of holders of not less than 66.67% of our
outstanding capital stock entitled to vote generally in the election of
directors. These provisions, when coupled with the provision of our amended and
restated certificate of incorporation authorizing the board of directors to fill
vacant directorships, may delay a stockholder from removing incumbent directors
and simultaneously gaining control of the board of directors by filling the
vacancies created by such removal with its own nominees.

STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS

    Our amended and restated certificate of incorporation eliminates the ability
of stockholders to act by written consent. Our amended and restated bylaws
further provide that special meetings of our stockholders may be called only by
the chairman of the board of directors or the president at the request of two-
thirds of the board of directors.

ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTORS NOMINATIONS

    Our amended and restated bylaws provide that stockholders seeking to bring
business before an annual meeting of stockholders, or to nominate candidates for
election as directors at an annual meeting of stockholders, must provide timely
notice thereof in writing. To be timely, a stockholder's notice must be received
at our principal executive offices not less than 90 days nor more than 120 days
prior to the anniversary date of the immediately preceding annual meeting of
stockholders. In the event that the annual meeting is called for a date that is
not within 30 days before or 70 days after the anniversary date, in order to be
timely, notice from the stockholder must be received:

    - not earlier than 120 days prior to the annual meeting of stockholders, and

    - not later than 90 days prior to the annual meeting of stockholders or the
      tenth day following the date on which notice of the annual meeting was
      made public.

    In the case of a special meeting of stockholders called for the purpose of
electing directors, notice by the stockholder, in order to be timely, must be
received:

    - not earlier than 120 days prior to the special meeting, and

    - not later than 90 days prior to the special meeting or the close of
      business on the tenth day following the day on which public disclosure of
      the date of the special meeting was made.

                                       66
<PAGE>
    Our amended and restated bylaws also specify certain requirements as to the
form and content of a stockholder's notice. These provisions may preclude
stockholders from bringing matters before an annual meeting of stockholders or
from making nominations for directors at an annual meeting of stockholders.

AUTHORIZED BUT UNISSUED SHARES

    The authorized but unissued shares of common stock and preferred stock are
available for future issuance without stockholder approval. These additional
shares may be utilized for a variety of corporate purposes, including future
public offerings to raise additional capital, corporate acquisitions and
employee benefit plans. The existence of authorized but unissued shares of
common stock and preferred stock could render more difficult or discourage an
attempt to obtain control of us by means of a proxy contest, tender offer,
merger or otherwise.

AMENDMENTS; SUPERMAJORITY VOTE REQUIREMENTS

    The Delaware General Corporation Law provides generally that the affirmative
vote of a majority of the shares entitled to vote on any matter is required to
amend a corporation's certificate of incorporation or bylaws, unless a
corporation's certificate of incorporation or bylaws, as the case may be,
requires a greater percentage. Our amended and restated certificate of
incorporation imposes supermajority vote requirements in connection with various
business combination transactions and the amendment of various provisions of our
amended and restated certificate of incorporation and amended and restated
bylaws, including those provisions relating to the classified board of directors
and the ability of stockholders to call special meetings.

RIGHTS AGREEMENT

    Under Delaware law, every corporation may create and issue rights entitling
the holders of such rights to purchase from the corporation shares of its
capital stock of any class or classes, subject to any provisions in its
certificate of incorporation. The price and terms of such shares must be stated
in the certificate of incorporation or in a resolution adopted by the board of
directors for the creation or issuance of such rights.

    We have entered into a stockholder rights agreement. As with most
stockholder rights agreements, the terms of our rights agreement are complex and
not easily summarized, particularly as they relate to the acquisition of our
common stock and to exercisability. This summary may not contain all of the
information that is important to you.

    Our rights agreement provides that each share of our common stock
outstanding will have one right to purchase one ten-thousandth of a preferred
share attached to it. The purchase price per one ten-thousandth of a preferred
share under the stockholder rights agreement is four times the average closing
price of our common stock for the first five days of trading after the
consummation of this offering.

    Initially, the rights under our rights agreement are attached to outstanding
certificates representing our common stock and no separate certificates
representing the rights will be distributed. The rights will separate from our
common stock and be represented by separate certificates on the day someone
acquires 15% of our common stock, or approximately 10 days after someone
commences a tender offer for 15% of our outstanding common stock.

    After the rights separate from our common stock, certificates representing
the rights will be mailed to record holders of the common stock. Once
distributed, the rights certificates alone will represent the rights.

    All shares of our common stock issued prior to the date the rights separate
from the common stock will be issued with the rights attached. The rights are
not exercisable until the date the rights separate from the common stock. The
rights will expire on the tenth anniversary of the date of the completion of
this offering unless earlier redeemed or exchanged by us.

    If an acquiror obtains or has the rights to obtain 15% or more of our common
stock, then each right will entitle the holder to

                                       67
<PAGE>
purchase a number of one ten-thousandths of a preferred share having a market
value of twice the purchase price of each right.

    Each right will entitle the holder to purchase a number of shares of common
stock of the acquiror having a then current market value of twice the purchase
price if an acquiror obtains 15% or more of our common stock and any of the
following occurs:

    - we merge into another entity;

    - an acquiring entity merges into us; or

    - we sell more than 50% of our assets or earning power.

    Under our rights agreement, any rights that are or were owned by an acquiror
of more than 15% of our outstanding common stock will be null and void.

    Our rights agreement contains exchange provisions which provide that after
an acquiror obtains 15% or more, but less than 50% of our respective outstanding
common stock, our board of directors may, at its option, exchange all or part of
the then outstanding and exercisable rights for common shares. In such an event,
the exchange ratio is one common share per right, adjusted to reflect any stock
split, stock dividend or similar transaction.

    Our board of directors may, at its option, redeem all of the outstanding
rights under our rights agreement prior to the earlier of (1) the time that an
acquiror obtains 15% or more of our outstanding common stock or (2) the final
expiration date of the rights agreement. The redemption price under our rights
agreement is $0.001 per right, subject to adjustment. The right to exercise the
rights will terminate upon the action of our board ordering the redemption of
the rights and the only right of the holders of the rights will be to receive
the redemption price.

    Holders of rights will have no rights as our stockholders including the
right to vote or receive dividends, simply by virtue of holding the rights.

    Our rights agreement provides that the provisions of the rights agreement
may be amended by the board of directors prior to the day someone acquires 15%
of our outstanding common stock or 10 days after someone commences a tender
offer for 15% of our outstanding common stock without the approval of the
holders of the rights. However, after that date, the rights agreement may not be
amended in any manner which would adversely effect the interests of the holders
of the rights, excluding the interests of any acquiror. In addition, our rights
agreement provides that no amendment may be made to adjust the time period
governing redemption at a time when the rights are not redeemable.

    Our rights agreement contains rights that have anti-takeover effects. The
rights may cause substantial dilution to a person or group that attempts to
acquire us without conditioning the offer on a substantial number of rights
being acquired. Accordingly, the existence of the rights may deter acquirors
from making takeover proposals or tender offers. However, the rights are not
intended to prevent a takeover, but rather are designed to enhance the ability
of our board to negotiate with an acquiror on behalf of all the stockholders. In
addition, the rights should not interfere with a proxy contest.

                          TRANSFER AGENT AND REGISTRAR

    The Transfer Agent and Registrar for StarMedia's common stock is American
Stock Transfer & Trust Company, New York, New York.

                                    LISTING

    Our common stock is quoted on the Nasdaq National Market under the trading
symbol "STRM".

<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE

    Sales of substantial amounts of our common stock in the public market could
adversely affect prevailing market prices of our common stock. Furthermore, many
sales of substantial amounts of common stock in the public market after
contractual and legal restrictions lapse could adversely affect the prevailing
market price and our ability to raise equity capital in the future.

    Upon completion of this offering, we will have outstanding an aggregate of
64,006,198 shares of our common stock, assuming no exercise of the underwriters'
over-allotment option and no exercise of outstanding options. Of these shares,
all of the shares sold in this offering will be freely tradable without
restriction or further registration under the Securities Act, unless the shares
are purchased by "affiliates" as that term is defined in Rule 144 under the
Securities Act. Of the remaining 58,006,198 shares of common stock held by
existing stockholders, 49,902,032 are "restricted securities" as that term is
defined in Rule 144 under the Securities Act. Restricted securities may be sold
in the public market only if registered or if they qualify for an exemption from
registration under Rule 144 or 701 under the Securities Act, which rules are
summarized below.

                               LOCK-UP AGREEMENTS

    Our officers, certain of our directors and Chase Venture Capital Associates,
L.P. have signed lock-up agreements under which they have agreed not to transfer
or dispose of, directly or indirectly, any shares of common stock or any
securities convertible into or exercisable or exchangeable for shares of common
stock, for a period of 90 days after the date of this prospectus. Transfers or
dispositions can be made sooner:

    - with the prior written consent of Goldman, Sachs & Co.;

    - in the case of some transfers to affiliates;

    - as a bona fide gift; or

    - to any trust.

    Approximately 21,970,811 shares of our common stock are subject to lock-up
agreements entered into in connection with our initial public offering that
expire on November 22, 1999, 22,606,151 shares of common stock are subject to
lock-up agreements that expire 90 days after the date of this prospectus, and
approximately 3,876,363 additional shares of our common stock are subject to
one-year lock-up agreements that expire in April and May 2000.

    Subject to the provisions of Rule 144, 144(k) and 701, restricted shares
totaling 1,448,707 will be available for sale in the public market, subject in
the case of shares held by affiliates to the volume restrictions contained in
those rules.

                                    RULE 144

    In general, under Rule 144 as currently in effect, a person who has
beneficially owned shares of our common stock for at least one year entitled to
sell within any three-month period a number of shares that does not exceed the
greater of:

    - 1% of the number of shares of common stock then outstanding, which will
      equal approximately 640,062 shares immediately after this offering; or

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

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

                                  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

                                       69
<PAGE>
an affiliate, is entitled to sell those shares without complying with the manner
of sale, public information, volume limitation or notice provisions of Rule 144.
Therefore, unless otherwise restricted, "144(k) shares" may be sold at any time.

                                    RULE 701

    In general, under Rule 701 of the Securities Act as currently in effect,
each of our employees, consultants or advisors who purchases shares from us in
connection with a compensatory stock plan or other written agreement is eligible
to resell such shares in reliance on Rule 144, but without compliance with some
of the restrictions, including the holding period, contained in Rule 144.

                              REGISTRATION RIGHTS

    Upon completion of this offering, the holders of 41,771,818 shares of our
common stock, or their transferees will be entitled to request that we register
their shares under the Securities Act.

                                  STOCK PLANS

    At June 30, 1999, options to purchase 7,271,533 shares were issued and
outstanding under our Plans and otherwise. 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.

                            VALIDITY OF COMMON STOCK

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors and Stockholders
StarMedia Network, Inc.

    We have audited the accompanying consolidated balance sheets of StarMedia
Network, Inc. (the "Company") as of December 31, 1997 and 1998 and June 30,
1999, and the related consolidated statements of operations, changes in
stockholders' equity and cash flows for the period from March 5, 1996 (date of
inception) to December 31, 1996, the years ended December 31, 1997 and 1998 and
the six months ended June 30, 1999. These consolidated financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

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

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
StarMedia Network, Inc. at December 31, 1997 and 1998 and June 30, 1999 and the
results of their operations and their cash flows for the period from March 5,
1996 (date of inception) to December 31, 1996, the years ended December 31, 1997
and 1998 and the six months ended June 30, 1999 in conformity with generally
accepted accounting principles.

1. SIGNIFICANT ACCOUNTING POLICIES

CONSOLIDATION AND DESCRIPTION OF BUSINESS

The accompanying consolidated financial statements include the accounts of
StarMedia Network, Inc. and its wholly-owned subsidiaries (collectively, the
"Company"). All intercompany account balances and transactions have been
eliminated in consolidation. StarMedia Network, Inc. was incorporated under
Delaware law in March 1996.

The Company is the leading Internet media company targeting Latin America and
other Spanish-and Portuguese-speaking markets worldwide. The Company's network
consists of interest-specific channels, extensive Web-based community features,
sophisticated search capabilities and access to online shopping in Spanish and
Portuguese. These channels cover topics of interest to Latin Americans online,
including local and regional news, business and sports. The Company promotes
user affinity to the StarMedia community by providing Spanish- and
Portuguese-language e-mail, chat rooms, instant messaging and personal
homepages. During 1999, the Company also launched sales offices in Spain and
Puerto Rico and began hiring regional sales managers throughout the United
States, focusing on those regions with large Spanish-speaking populations.

The accompanying consolidated financial statements have been restated to reflect
the May 26, 1999 acquisition of Wass Net, S.L. ("Wass Net"), which was accounted
for as a pooling-of-interests. (See Note 4.)

INTERIM FINANCIAL STATEMENTS

The financial statements as of June 30, 1998, and for the six months ended June
30, 1998 have been prepared by the Company without audit. In the opinion of
management, all adjustments (which include only normal recurring adjustments)
necessary to present fairly the financial position as of June 30, 1998 and the
results of operations and cash flows for the six months ended June 30, 1998 have
been made. Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or eliminated.

REVENUE RECOGNITION

The Company's revenues are derived principally from the sale of banner
advertisements and sponsorships, some of which also involve more integration,
design and coordination of the customer's content with the Company's services,
such as the placement of sponsor buttons in specific areas of the Network. The
sponsor buttons generally provide users with direct links to sponsor homepages
that exist within the Network which are usually focused on selling sponsor

                THE SIX MONTHS ENDED JUNE 30, 1998 IS UNAUDITED)

merchandise and services to users of the Network. Advertising revenues on both
banner and sponsorship contracts, which range from one month to two years, are
recognized ratably in the period in which the advertisement is displayed,
provided that no significant Company obligations remain and collection of the
resulting receivable is probable. Company obligations typically include
guarantees of minimum number of "impressions," or times that an advertisement
appears in pages viewed by users of the Company's Network. To the extent minimum
guaranteed impressions are not met, the Company defers recognition of the
corresponding revenues until the remaining guaranteed impression levels are
achieved. The Company also earns revenues on sponsorship contracts for fees
relating to the design, coordination, and integration of the customer's content.
Revenue related to the design, coordination and integration of the customers'
content are recognized ratably over the term of the contract or using the
percentage of completion method if the fee for such services is fixed. A number
of the Company's agreements provide for the Company to receive a percentage of
revenues from electronic commerce transactions conducted by advertisers who are
selling goods or services to users of the Network. These revenues are recognized
by the Company upon notification from the advertiser of its share of revenues
earned by the Company and, to date, have not been significant.

Revenues from barter transactions are recognized during the period in which the
advertisements are displayed on the Company's Network. Barter transactions are
recorded at the estimated fair market value of the goods or services received or
the estimated fair market value of the advertisements given, whichever is more
readily determinable. For the year ended December 31, 1997, substantially all of
the Company's revenues were derived from barter transactions. For the year ended
December 31, 1998 and the six months ended June 30, 1998 and 1999, revenues
derived from barter transactions, were approximately $2,400,000, $500,000 and
$1,900,000, respectively.

Deferred revenues are primarily comprised of billings in excess of recognized
revenues relating to advertising contracts and sponsorship and banner
advertising contracts.

PRODUCT DEVELOPMENT

Costs incurred in the classification and organization of listings within the
Network and the development of new products and enhancements to existing
products are charged to expense as incurred. Statement of Financial Accounting
Standards ("SFAS") No. 86, "Accounting for the Costs of Computer Software to be
Sold, Leased or Otherwise Marketed," requires capitalization of certain software
development costs subsequent to the establishment of technological feasibility.
Based upon the Company's product development process, technological feasibility
is established upon completion of a working model. Costs incurred by the Company
between completion of the working model and the point at which the product is
ready for general release have been insignificant.

CASH AND CASH EQUIVALENTS

The Company considers all financial instruments with a maturity of three months
or less when purchased to be cash equivalents. Such amounts are stated at cost
which approximates market value.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                    (INFORMATION AS OF JUNE 30, 1998 AND FOR
                THE SIX MONTHS ENDED JUNE 30, 1998 IS UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
FIXED ASSETS

Fixed assets, including those acquired under capital leases, are stated at cost
and depreciated by the straight-line method over the estimated useful lives of
the assets, which range from three to five years. Leasehold improvements are
amortized over the lesser of the useful life of the asset or the remaining
period of the lease.

INTANGIBLE ASSETS

Intangible assets consist of trademarks and trade names and are being amortized
on a straight-line basis over a period of five years.

Goodwill consists of the excess of the purchase price paid over the tangible net
assets of acquired companies. Goodwill is amortized using the straight-line
method over three years. Amortization expense and accumulated amortization as of
June 30, 1999 and for the six months ended June 30, 1999 were approximately
$538,000.

The Company assesses the recoverability of its goodwill and intangible assets by
determining whether the amortization of the unamortized balance over its
remaining life can be recovered through forecasted cash flows. If undiscounted
forecasted cash flows indicate that the unamortized amounts will not be
recovered, an adjustment will be made to reduce the net amounts to an amount
consistent with forecasted future cash flows discounted at the Company's
incremental borrowing rate. Cash flow forecasts are based on trends of
historical performance and management's estimate of future performance, giving
consideration to existing and anticipated competitive and economic conditions.

INCOME TAXES

The Company uses the liability method of accounting for income taxes, whereby
deferred income taxes are provided on items recognized for financial reporting
purposes over different periods than for income tax purposes. Valuation
allowances are provided when the expected realization of tax assets does not
meet a more likely than not criteria.

ADVERTISING COSTS

Advertising costs are expensed as incurred. For the period from March 5, 1996
(date of inception) to December 31, 1996, the years ended December 31, 1997 and
1998 and the six months ended June 30, 1998 and 1999, advertising expense
amounted to approximately $0, $1,610,000, $21,246,000, $4,578,000 and

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 amounts reported in the financial statements and footnotes thereto.
Actual results could differ from those estimates.

STOCK-BASED COMPENSATION

The Company grants stock options generally for a fixed number of shares to
certain employees with an exercise price equal to or below the fair value of the
shares at the date of grant. The Company accounts for stock option grants in
accordance with Accounting Principles Board ("APB") Opinion No. 25, "Accounting
for Stock Issued to Employees", and, accordingly, recognizes compensation
expense only if the fair value of the underlying Common Stock exceeds the
exercise price of the stock option on the date of grant. In October 1995, the
FASB issued SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS No.
123"), which provides an alternative to APB Opinion No. 25 in accounting for
stock-based compensation. As permitted by SFAS No. 123, the Company continues to
account for stock-based compensation in accordance with APB Opinion No. 25 and
has elected the pro forma disclosure alternative of SFAS No. 123 (See Note 6).

COMPUTATION OF HISTORICAL NET LOSS PER SHARE

The Company calculates earnings per share in accordance with SFAS No. 128,
"Computation of Earnings Per Share" and SEC Staff Accounting Bulletin No. 98.
Accordingly, basic earnings per share is computed using the weighted average
number of common and dilutive common equivalent shares outstanding during the
period. Common equivalent shares consist of the incremental common shares
issuable upon the conversion of the Preferred Stock (using the if-converted
method) and shares issuable upon the exercise of stock options (using the
treasury stock method); common equivalent shares are excluded from the
calculation if their effect is anti-dilutive.

CONCENTRATIONS OF CREDIT RISK

Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash and cash equivalents
and accounts receivable. The Company maintains the majority of its cash and cash
equivalents with one financial institution. The Company's sales are primarily to
companies located in the United States and Latin American region. The Company
performs periodic credit evaluations of its customers' financial condition and
does not require collateral. Accounts receivable are due principally from large
U.S. companies under stated contract terms and the Company provides for
estimated credit losses at the time of sale. Such losses have not been
significant to date.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts reported in the consolidated balance sheets for cash and
cash equivalents, accounts receivable, accounts payable and loan payable
approximate their fair values.

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
FOREIGN CURRENCY AND INTERNATIONAL OPERATIONS

The functional currency of the Company's active subsidiaries in Argentina,
Brazil, Chile, Spain and Colombia is the local currency. The financial
statements of these subsidiaries are translated to U.S. dollars using period-end
rates of exchange for assets and liabilities, and average rates for the period
for revenues and expenses. Translation gains and losses are deferred and
accumulated as a component of stockholders' equity. The functional currency of
the Company's subsidiaries in highly inflationary economies, Mexico, Uruguay,
and Venezuela, is the U.S. dollar. Accordingly, for those subsidiaries that use
U.S. dollars as the functional currency, monetary assets and liabilities are
translated using the current exchange rate in effect at the period-end date,
while nonmonetary assets and liabilities are translated at historical rates.
Operations are generally translated at the weighted average exchange rate in
effect during the period. The resulting foreign exchange gains and losses are
recorded in the consolidated statement of operations. Revenues earned by the
Company's foreign subsidiaries and assets of such foreign subsidiaries were not
significant for all periods presented or at December 31, 1997, 1998 and June 30,
1999. Commencing January 1, 1999, the functional currency of the Company's
Mexican subsidiary changed from the U.S. dollar to the local currency as Mexico
was no longer considered a hyper-inflationary economy.

COMPREHENSIVE INCOME

The Company reports comprehensive income in accordance with SFAS No. 130,
"Reporting Comprehensive Income." SFAS No. 130 establishes rules for the
reporting and display of comprehensive income and its components. SFAS No. 130
requires foreign currency translation adjustments to be included in other
comprehensive loss.

SEGMENT INFORMATION

The Company discloses information regarding segments in accordance with SFAS No.
131, "Disclosures about Segments of an Enterprise and Related Information." SFAS
No. 131 establishes standards for reporting of financial information about
operating segments in annual financial statements and requires reporting
selected information about operating segments in interim financial reports. The
disclosure of segment information was not required as the Company operates in
only one business segment.

As of and for the period and years ended December 31, 1996, 1997 and 1998 and
June 30, 1999, substantially all of the Company's assets were located in the
U.S. and the Company derived substantially all of its revenue from businesses
located in the U.S.

3. STOCKHOLDERS' (DEFICIT) EQUITY

Between April 30 and May 5, 1999, a group of third party investors purchased an
aggregate of 3,727,272 shares of the Company's common stock at $11 per share, or
approximately $41,000,000, less fees and commissions of $1,640,000 paid by
issuing 149,091 shares of the Company's common stock. These investors are
subject to a one-year restriction on the sale or transfer of such shares, after
which such investors have been granted certain registration rights.

On May 25, 1999, the Company's initial public offering ("IPO") was declared
effective by the SEC. The Company realized proceeds of approximately
$110,400,000, net of underwriting discounts and commissions and related
expenses, from the initial public offering of 8,050,000 shares of its common
stock.

On May 26, 1999, the Company issued 1,133,334 shares of its common stock in
connection with the Wass Net merger.

On June 26, 1999, the Company issued 20,000 shares of its common stock in
connection with an acquisition valued at $1,000,000.

During the six months ended June 30, 1999, the Company issued 1,753,636 shares
of its common stock for $2,016,000 in connection with the exercise of stock
options.

REDEEMABLE CONVERTIBLE PREFERRED STOCK

In July 1997, the Company sold 7,330,000 shares of Series A Redeemable
Convertible Preferred Stock (the "Series A Preferred") for $3,665,000, or $.50
per share. In February 1998, the Company sold 8,000,000 shares of Series B
Redeemable Convertible Stock (the "Series B Preferred") for $12,000,000, or
$1.50 per share. In August and September 1998, the Company sold an aggregate
16,666,667 shares of Series C Redeemable Convertible Preferred Stock (the
"Series C Preferred") for $80,000,000, or $4.80 per share. The Series A
Preferred, Series B Preferred and the Series C Preferred (collectively, the
"Preferred Stock") were convertible into common stock on a one for one basis,
subject to certain anti-dilution provisions, as defined, at any time at the
option of the holder or automatically in the event of a qualified IPO. The
holders of the Preferred Stock were entitled to the number of votes equal to the
number of common shares that could be obtained upon conversion on the date of
the vote and are entitled to a discretionary noncumulative dividend.

3. STOCKHOLDERS' (DEFICIT) EQUITY (CONTINUED)

Upon a liquidation, including any merger or acquisition where the existing
stockholders of the Company own less than 50% of the successor entity, the
holders of the Preferred Stock were entitled to have the Company redeem their
shares at the original price paid per share (the "Original Investment"), plus a
10% cumulative return less any dividends paid.

In the event that the Preferred Stock had not been converted as of December 31,
2004, the holders of the Preferred Stock could elect to have the Company redeem
their Preferred Stock for an amount equal to their original investment plus any
dividends declared but unpaid.

The Preferred Stock was converted into 31,996,667 shares common stocks on a
one-for-one basis, upon the consummation of the IPO. No Preferred Stock
dividends had been declared or paid. At December 31, 1997 and 1998, and at the
date of conversion total cumulative dividends in arrears, that would be payable
upon a liquidation, were approximately $183,000, $4,233,000 and $8,499,000,
respectively.

The Company has recorded issuance costs incurred in connection with the
Preferred Stock as discounts at issuance and accreted the discounts from the
date of issuance through the date of mandatory redemption on December 31, 2004.

CONVERTIBLE SUBORDINATED NOTES

In January 1998 the Company issued $4,000,000 8% convertible subordinated notes
due at the earlier of the closing of the Series B Preferred financing, or on
July 21, 1998. In August 1998 the Company issued $2,000,000 8% convertible
subordinated notes due at the earlier of the closing of the Series C Preferred
financing or on December 31, 1998. All amounts outstanding were repaid during
1998 in accordance with their terms.

expense, estimated to be $3,000,000, when and if such performance targets are
met.

SERVICIOS INTERACTIVOS LIMITADA

In June 1999, the Company acquired all the outstanding stock of Servicios
Interactivos Limitada ("SIL") for 20,000 shares of the Company's common stock.

acquisitions. The excess purchase price over the fair value of the net assets
acquired, including expenses incurred by the Company, has been recorded as
goodwill. Goodwill resulting from the acquisitions of approximately $7,967,000
is being amortized using the straight-line method over three years.

The pro forma unaudited consolidated results of operations, assuming the
consummation of the KD Sistemas acquisition as of January 1, 1998, are as

per share would have been immaterial.

WASS NET, S.L.

Effective May 26, 1999, the Company acquired all of the outstanding stock of
Wass Net, a company organized under the laws of Spain. The acquisition was

common stock for each outstanding Wass Net share. Accordingly, the Company
issued 1,133,334 shares of its common stock for all the outstanding shares of
Wass Net stock. Wass Net is a Spanish-language online community offering e-mail,

6. STOCK OPTIONS

    In January 1997, the Company adopted the 1997 Stock Option Plan and, in July
1998, the Company adopted the 1998 Stock Option Plan (collectively, the "Option
Plans"). The 1997 Stock Option Plan and the 1998 Stock Plan provide for the
authorization of 10,000,000 shares. In February 1999, an additional 7,000,000
shares were reserved for issuance pursuant to the 1998 Stock Option Plan. The
Option Plans provide for the granting of incentive stock options or
non-qualified stock options to purchase common stock to eligible participants.
Options granted under the Option Plan are for periods not to exceed ten years.
In July 1998, approximately 1,400,000 non-qualified options outstanding were
exchanged for incentive stock options having generally equivalent terms as the
non-qualified options.

    Other than options to purchase 2,000,000 and 1,500,000 shares granted in
April and December 1998, respectively, which were immediately vested, options
outstanding under the Option Plans generally vest one-third after the first year
of service and ratably each month over the next two years.

    In connection with the granting of stock options in 1998 and the exchange of
non-qualified options to incentive stock options, the Company recorded deferred
compensation of approximately $19,087,000. In connection with the granting of
stock options in 1999, the Company recorded additional deferred compensation of
approximately $5,955,000. Deferred compensation is being

Company became a public entity will include an expected volatility factor in
addition to the factors described in the preceding paragraph, the above results
may not be representative of future periods. No options were granted subsequent

                       NOTES TO THE FINANCIAL STATEMENTS

                            AS OF DECEMBER 31, 1998

                      (AMOUNTS EXPRESSED IN U.S. DOLLARS)

1. BACKGROUND

    KD Sistemas de Informacao Ltda. was incorporated on January 2, 1996 under
the laws of the Federal Republic of Brazil. Initially denominated Skynet
Sistemas Ltda., the Company developed and maintains www.cade.com.br, a branded
Internet on-line network ("the network") located in the World Wide Web ("the
Web"). The network develops, trains and provides systems and a search engine for
Internet network purposes. The Company also provides graphic arts, editing of
virtual programs, publicity, consulting, and other community Internet features
targeted to the Brazilian market.

2. BASIS OF PRESENTATION

    The Company is required to maintain its books and records in local currency
(Brazilian reais) and in the Portuguese language, based on generally accepted
accounting principles in Brazil. All of the Company's sales and other
transactions are denominated in local currency.

    The Company's official financial statements as of December 31, 1998 were
originally prepared in local currency and in the Portuguese language. The
accompanying financial statements herein presented have been translated into
U.S. dollars and adjusted to be in conformity with generally accepted accounting
principles in the United States (U.S. GAAP), in accordance with the criteria set
forth in Statement of Financial Accounting Standards 52 (SFAS 52).

    As from July 1, 1997, the Brazilian economy had ceased to be highly
inflationary so the functional currency (U.S. dollars) was changed to the local
currency (Brazilian reais).

    The accompanying financial statements stated in U.S. dollars have been
translated at the official exchange rate prevailing at December 31, 1998 of
R$1.2087 to US$1.00. The criteria for translating the revenue and expense
accounts is the average rate of January 31, 1998 and December 31, 1998 or
R$1.1626, which does not differ significantly from using the average monthly
rate. The gain or loss resulting from this translation process is included in
the Cumulative Translation Adjustments component of stockholders' equity.

3. SIGNIFICANT ACCOUNTING POLICIES

    The significant accounting policies followed in the preparation and
presentation of the financial statements are summarized as follows:

    a.  Cash and banks are stated at cost.

    b.  Short-term investments are stated at the lower of the market value of
       the investment funds quota value at the balance sheet date or cost plus
       income accrued to the balance sheet date.

    c.  Assets and liabilities to be realized or paid within 12 months following
       the balance sheet dates are classified as current assets and current
       liabilities, respectively.

    d.  Property, plant and equipment are stated at cost of purchase or
       construction less accumulated depreciation. Depreciation is calculated
       using the straight-line method. The annual rates used take into
       consideration the estimated useful lives of the assets.

                      (AMOUNTS EXPRESSED IN U.S. DOLLARS)

3. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    e.  Revenues, costs and expenses are recognized on the accrual basis. The
       Company's revenues are derived from the sale of advertisements.
       Advertising revenues are recognized ratably in the period in which the
       advertisement is displayed, provided that no significant Company
       obligations remain outstanding and collection of the resulting receivable
       is probable.

    f.  Accrued salaries are fully accrued liabilities for future compensation
       to employees for vacations vested during the year.

    g.  The Company pays the corporate income tax and social contribution on
       profits based on the Presumed Profit Computation. Such method consists,
       basically, of the calculation of the above taxes through the calculation
       of 32% and 12%, respectively, on the revenues of the Company. On this
       amount, called Presumed Profits, the income tax, at the rate of 15% plus
       surtax of 10% on presumed profits exceeding 20,000 Brazilian reais per
       month, and the social contribution, at the rate of 8%, apply.

10. SUBSEQUENT EVENT

    EXCHANGE POLICY

    On January 13, 1999, the Brazilian Central Bank changed its exchange policy,
discontinuing the so-called exchange band through which it controlled the real
fluctuation margin in relation to the U.S. dollar; therefore, the exchange rate
was freely negotiated in the market. As a consequence of such change, the real
had devalued in relation to the U.S. dollar, from R$1.2087 per U.S. dollar at
December 31, 1998 to R$1.7597 per U.S. dollar at June 10, 1999. It is still not
possible to determine if the U.S. dollar quotation will remain at this level and
its impact on the Company's transactions and financial position.

    CHANGE IN CONTROL

    On April 13, 1999 the stockholders' entered into an agreement with StarMedia
Network Inc., an U.S. corporation, and sold all the outstanding equity interest
in the Company.

                  NOTES TO THE UNAUDITED FINANCIAL STATEMENTS

                         AS OF MARCH 31, 1999 AND 1998

                      (AMOUNTS EXPRESSED IN U.S. DOLLARS)

1. BACKGROUND

    KD Sistemas de Informacao Ltda. was incorporated on January 2, 1996 under
the laws of the Federative Republic of Brazil. Initially denominated Skynet
Sistemas Ltda., the Company developed and maintains www.cade.com.br, a branded
Internet on-line network ("the network") located in the World Wide Web ("the
Web"). The network develops, trains and provides systems and a search engine for
Internet network purposes. The Company also provides graphic arts, editing of
virtual programs, publicity, consulting, and other community Internet features
targeted to the Brazilian market.

2. BASIS OF PRESENTATION

    The Company is required to maintain its books and records in local currency
(Brazilian reais) and in the Portuguese language, based on generally accepted
accounting principles in Brazil.

    The Company's official financial statements as of March 31, 1999 and 1998
were originally prepared in local currency and in the Portuguese language. The
accompanying financial statements herein presented have been translated into
U.S. dollars and adjusted to be in conformity with generally accepted accounting
principles in the United States (U.S. GAAP), in accordance with the criteria set
forth in Statement of Financial Accounting Standards 52 (SFAS 52).

    As from July 1, 1997, the Brazilian economy had ceased to be highly
inflationary so the functional currency (U.S. dollars) was changed to the local
currency (Brazilian reais).

    The accompanying financial statements stated in U.S. dollars have been
translated at the official exchange rate prevailing at March 31, 1999 (R$1.7220
to US$1.00) and March 31, 1998 (R$1.1374 to US$1.00). The criteria for
translating the revenue and expense accounts are the average rates prevailing
during the period. The gain or loss resulting from this translation process is
included in the Cumulative Translation Adjustment component of stockholders'
equity.

    The unaudited financial statements as of March 31, 1999 and 1998 include, in
the opinion of the management, all adjustments (which are of a normal recurring
nature) necessary for fair presentation thereof. The results of operations for
the three-month period ended March 31, 1999 are not necessarily indicative of
the results for the full fiscal year ending December 31, 1999.

3. SIGNIFICANT ACCOUNTING POLICIES

    The significant accounting policies followed in the preparation and
presentation of the financial statements are summarized as follows:

    a.  Cash and banks are stated at cost.

    b.  Short-term investments are stated at the lower of the market value of
       the investment funds quota value at the balance sheet date or cost plus
       income accrued to the balance sheet date.

    c.  Assets and liabilities to be realized or paid within 12 months following
       the balance sheet dates are classified as current assets and current
       liabilities, respectively.

            NOTES TO THE UNAUDITED FINANCIAL STATEMENTS (CONTINUED)

                         AS OF MARCH 31, 1999 AND 1998

                      (AMOUNTS EXPRESSED IN U.S. DOLLARS)

3. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    d.  Property, plant and equipment are stated at cost of purchase or
       construction less accumulated depreciation. Depreciation is calculated
       using the straight-line method. The annual rates used take into
       consideration the estimated useful lives of the assets.

    e.  Revenues, costs and expenses are recognized on the accrual basis. The
       Company's revenues are derived from the sale of advertisements.
       Advertising revenues are recognized ratably in the period in which the
       advertisement is displayed, provided that no significant Company
       obligations remain outstanding and collection of the resulting receivable
       is probable.

    f.  Accrued salaries are fully accrued liabilities for future compensation
       to employees for vacations vested during the year.

    g.  The Company pays the corporate income tax and social contribution on
       profits based on the Presumed Profit Computation. Such method consists,
       basically, of the calculation of the above taxes through the calculation
       of 32% and 12%, respectively, on the revenues of the Company. On this
       amount, called Presumed Profits, the income tax, at the rate of 15% plus
       surtax of 10% on all amounts exceeding 20,000 Brazilian reais of presumed
       profit per month, and the social contribution, at the rate of 8%, apply.

4. SHORT-TERM INVESTMENTS

    As of March 31, 1999 and 1998, short-term investments were comprised of
financial investment fund--fixed income, denominated in Brazilian reais at Banco
Brasileiro de Descontos--BRADESCO, in the total amount of US$216,091 and
US$112,437, respectively.

10. RELEVANT ISSUE

    On January 13, 1999, the Brazilian Central Bank changed its exchange policy,
discontinuing the so-called exchange band through which it controlled the real
fluctuation margin in relation to the U.S. dollar; therefore, the exchange rate
was freely negotiated in the market. As a consequence of such change, the real
had devalued in relation to the U.S. dollar, from R$1.2087 per U.S. dollar at
December 31, 1998 to R$1.7597 per U.S. dollar at June 10, 1999. It is still not
possible to determine if the U.S. dollar quotation will remain at this level and
its impact on the Company's transactions and financial position.

11. SUBSEQUENT EVENT

    On April 13, 1999 the Company's stockholders' entered into an agreement with
StarMedia Network Inc., a U.S. corporation, and sold all the outstanding equity
interest in the Company.

       PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

    On April 13, 1999, StarMedia Network, Inc. (the "Company") acquired all of
the outstanding stock of KD Sistemas De Informacao Ltda. ("KD Sistemas"), a
Brazilian company. As a result of the acquisition, KD Sistemas became a
wholly-owned subsidiary of the Company. The purchase price consisted of a cash
payment of $5,000,000 at closing, $890,000 payable in March 2000, and additional
estimated cash payments of up to $6,400,000, in the aggregate, due in March
2000, 2001, and 2002 upon the achievement of certain performance targets (the
"Earn-out"), plus related expenses of approximately $250,000. As a portion of
the Earn-out is contingent upon the continued employment of certain key
individuals, the Company will record a portion of such payments as compensation
expense, estimated to be $3,000,000 when and if such performance targets are
met. The KD Sistemas acquisition was accounted for as a purchase.

    The pro forma condensed consolidated statements of operations for the year
ended December 31, 1998 and the six months ended June 30, 1999 assume that the
KD Sistemas acquisition occurred as of January 1, 1998. The unaudited pro forma
statements of operations for the year ended December 31, 1998 and the six months
ended June 30, 1999 are based on the supplemental consolidated statements of
operations for the Company for the year ended December 31, 1998 and the six
months ended June 30, 1999, the historical financial statements of KD Sistemas
for the year ended December 31, 1998 and the period from January 1, 1999 through
April 13, 1999.

    The pro forma condensed consolidated statements of operations have been
prepared by the Company's management. The pro forma consolidated financial
statements may not be indicative of the results that actually would have
occurred if the acquisitions had been consummated on the respective dates
indicated or which may be obtained in the future. The pro forma condensed
consolidated financial statements should be read in conjunction with financial
statements and notes of the Company and KD Sistemas.

    The Company's supplemental consolidated financial statements have been
prepared to give retroactive effect to the Webcast Merger which is being
accounted as a pooling of interests. These supplemental consolidated financial
statements will become the historical consolidated financial statements of the
Company after financial statements covering the consummation date of the Webcast
Merger are issued.

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors and Stockholders
StarMedia Network, Inc.

We have audited the accompanying supplemental consolidated balance sheets of
Starmedia Network, Inc. (the "Company") (formed as a result of the consolidation
of the Company and Webcast Solutions, Inc. ("Webcast")) as of December 31, 1997
and 1998 and June 30, 1999 and the related supplemental consolidated statements
of operations, changes in stockholders' equity and cash flows for the period
from March 5, 1996 (date of inception) to December 31, 1996, the years ended
December 31, 1997 and 1998 and the six months ended June 30, 1999. The
supplemental consolidated financial statements give retroactive effect to the
merger of the Company and Webcast on September 14, 1999, which has been
accounted for using the pooling of interests method as described in the notes to
the supplemental consolidated financial statements. These supplemental financial
statements are the responsibility of the management of the Company. Our
responsibility is to express an opinion on these supplemental 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 financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the supplemental consolidated financial statements referred to
above present fairly, in all material respects, the consolidated financial
position of the Company at December 31, 1997 and 1998 and June 30, 1999, and the
results of their operations and their cash flows for the period from March 5,
1996 (date of inception) to December 31, 1996, the years ended December 31, 1997
and 1998 and the six months ended June 30, 1999, after giving retroactive effect
to the merger of Webcast as described in the notes to the supplemental
consolidated financial statements, in conformity with generally accepted
accounting principles.

1. SIGNIFICANT ACCOUNTING POLICIES

CONSOLIDATION AND DESCRIPTION OF BUSINESS

The supplemental consolidated financial statements of Starmedia Network, Inc.
and its wholly-owned subsidiaries (collectively the "Company") have been
prepared to give retroactive effect to the merger with Webcast Solutions, Inc.
("Webcast") on September 14, 1999, (the "Webcast Merger"). The
pooling-of-interest method of accounting requires the restatement of all periods
as if the Company and Webcast had always been combined. Webcast was incorporated
on July 24, 1998. Generally accepted accounting principles proscribe giving
effect to a consummated business combination accounted for as a
pooling-of-interests that do not include the date of combination. These
supplemental consolidated financial statements included do not extend through
the date of consummation; however, they will become the historical consolidated
financial statements of the Company after financial statements covering the
consummation date of the Webcast Merger are issued. (See Notes 3, 4 and 6).

All intercompany account balances and transactions have been eliminated in
consolidation. StarMedia Network, Inc. was incorporated under Delaware law in
March 1996.

The Company is the leading Internet media company targeting Latin America and
other Spanish-and Portuguese-speaking markets worldwide. The Company's network
consists of interest-specific channels, extensive Web-based community features,
sophisticated search capabilities and access to online shopping in Spanish and
Portuguese. These channels cover topics of interest to Latin Americans online,
including local and regional news, business and sports. The Company promotes
user affinity to the StarMedia community by providing Spanish- and
Portuguese-language e-mail, chat rooms, instant messaging and personal
homepages. During 1999, the Company also launched sales offices in Spain and
Puerto Rico and began hiring regional sales managers throughout the United
States, focusing on those regions with large Spanish-speaking populations.

The accompanying consolidated financial statements have been restated to reflect
the May 26, 1999 acquisition of Wass Net, S.L. ("Wass Net"), which was accounted
for as a pooling-of-interests. (See Note 4).

INTERIM FINANCIAL STATEMENTS

The financial statements as of June 30, 1998, and for the six months ended June
30, 1998 have been prepared by the Company without audit. In the opinion of
management, all adjustments (which include only normal recurring adjustments)
necessary to present fairly the financial position as of June 30, 1998 and the
results of operations and cash flows for the six months ended June 30, 1998 have
been made. Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or eliminated.

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
REVENUE RECOGNITION

The Company's revenues are derived principally from the sale of banner
advertisements and sponsorships, some of which also involve more integration,
design and coordination of the customer's content with the Company's services,
such as the placement of sponsor buttons in specific areas of the Network. The
sponsor buttons generally provide users with direct links to sponsor homepages
that exist within the Network which are usually focused on selling sponsor
merchandise and services to users of the Network. Advertising revenues on both
banner and sponsorship contracts, which range from one month to two years, are
recognized ratably in the period in which the advertisement is displayed,
provided that no significant Company obligations remain and collection of the
resulting receivable is probable. Company obligations typically include
guarantees of minimum number of "impressions," or times that an advertisement
appears in pages viewed by users of the Company's Network. To the extent minimum
guaranteed impressions are not met, the Company defers recognition of the
corresponding revenues until the remaining guaranteed impression levels are
achieved. The Company also earns revenues on sponsorship contracts for fees
relating to the design, coordination, and integration of the customer's content.
Revenue related to the design, coordination and integration of the customers'
content are recognized ratably over the term of the contract or using the
percentage of completion method if the fee for such services is fixed. A number
of the Company's agreements provide for the Company to receive a percentage of
revenues from electronic commerce transactions conducted by advertisers who are
selling goods or services to users of the Network. These revenues are recognized
by the Company upon notification from the advertiser of its share of revenues
earned by the Company and, to date, have not been significant.

Revenues from barter transactions are recognized during the period in which the
advertisements are displayed on the Company's Network. Barter transactions are
recorded at the estimated fair market value of the goods or services received or
the estimated fair market value of the advertisements given, whichever is more
readily determinable. For the year ended December 31, 1997, substantially all of
the Company's revenues were derived from barter transactions. For the year ended
December 31, 1998 and the six months ended June 30, 1998 and 1999, revenues
derived from barter transactions, were approximately $2,400,000, $500,000 and
$1,900,000, respectively.

Revenues derived from the Company's Webcast subsidiary related to webcasting
services are recognized during the period in which the webcasting services are
delivered. Revenues related to consulting and technical services from time and
material contracts are recognized during the period in which the related
services are provided and revenue from fixed price contracts is recognized using
the percentage-of-completion method.

Deferred revenues are primarily comprised of billings in excess of recognized
revenues relating to advertising contracts and sponsorship and banner
advertising contracts.

PRODUCT DEVELOPMENT

Costs incurred in the classification and organization of listings within the
Network and the development of new products and enhancements to existing
products are charged to expense as

incurred. Statement of Financial Accounting Standards ("SFAS") No. 86,
"Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise
Marketed," requires capitalization of certain software development costs
subsequent to the establishment of technological feasibility. Based upon the
Company's product development process, technological feasibility is established
upon completion of a working model. Costs incurred by the Company between
completion of the working model and the point at which the product is ready for
general release have been insignificant.

CASH AND CASH EQUIVALENTS

The Company considers all financial instruments with a maturity of three months
or less when purchased to be cash equivalents. Such amounts are stated at cost
which approximates market value.

FIXED ASSETS

Fixed assets, including those acquired under capital leases, are stated at cost
and depreciated by the straight-line method over the estimated useful lives of
the assets, which range from three to five years. Leasehold improvements are
amortized over the lesser of the useful life of the asset or the remaining
period of the lease.

INTANGIBLE ASSETS

Intangible assets consist of trademarks and trade names and are being amortized
on a straight-line basis over a period of five years.

Goodwill consists of the excess of the purchase price paid over the tangible net
assets of acquired companies. Goodwill is amortized using the straight-line
method over three years. Amortization expense and accumulated amortization as of
June 30, 1999 and for the six months ended June 30, 1999 was approximately
$538,000.

The Company assesses the recoverability of its goodwill and intangible assets by
determining whether the amortization of the unamortized balance over its
remaining life can be recovered through forecasted cash flows. If undiscounted
forecasted cash flows indicate that the unamortized amounts will not be
recovered, an adjustment will be made to reduce the net amounts to an amount
consistent with forecasted future cash flows discounted at the Company's
incremental borrowing rate. Cash flow forecasts are based on trends of
historical performance and management's estimate of future performance, giving
consideration to existing and anticipated competitive and economic conditions.

INCOME TAXES

The Company uses the liability method of accounting for income taxes, whereby
deferred income taxes are provided on items recognized for financial reporting
purposes over different periods than for income tax purposes. Valuation
allowances are provided when the expected realization of tax assets does not
meet a more likely than not criteria.

ADVERTISING COSTS

Advertising costs are expensed as incurred. For the period from March 5, 1996
(date of inception) to December 31, 1996, the years ended December 31, 1997 and
1998 and the six months ended June 30, 1998 and 1999, advertising expense
amounted to approximately $0, $1,610,000, $21,246,000, $4,578,000 and
$15,661,000, respectively. For the years ended December 31, 1997 and 1998 and
the six months ended June 30, 1998 and 1999, advertising expense includes
approximately $460,000, $2,400,000, $483,000 and $1,900,000 of charges related
to barter advertising transactions.

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 amounts reported in the financial statements and footnotes thereto.
Actual results could differ from those estimates.

STOCK-BASED COMPENSATION

The Company grants stock options generally for a fixed number of shares to
certain employees with an exercise price equal to or below the fair value of the
shares at the date of grant. The Company accounts for stock option grants in
accordance with Accounting Principles Board ("APB") Opinion No. 25, "Accounting
for Stock Issued to Employees", and, accordingly, recognizes compensation
expense only if the fair value of the underlying Common Stock exceeds the
exercise price of the stock option on the date of grant. In October 1995, the
FASB issued SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS No.
123"), which provides an alternative to APB Opinion No. 25 in accounting for
stock-based compensation. As permitted by SFAS No. 123, the Company continues to
account for stock-based compensation in accordance with APB Opinion No. 25 and
has elected the pro forma disclosure alternative of SFAS No. 123 (See Note 6).

COMPUTATION OF HISTORICAL NET LOSS PER SHARE

The Company calculates earnings per share in accordance with SFAS No. 128,
"Computation of Earnings Per Share" and SEC Staff Accounting Bulletin No. 98.
Accordingly, basic earnings per share is computed using the weighted average
number of common and dilutive common equivalent shares outstanding during the
period. Common equivalent shares consist of the incremental common shares
issuable upon the conversion of the Preferred Stock (using the if-converted
method) and shares issuable upon the exercise of stock options (using the
treasury stock method); common equivalent shares are excluded from the
calculation if their effect is anti-dilutive.

CONCENTRATIONS OF CREDIT RISK

Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash and cash equivalents
and accounts receivable. The Company maintains the majority of its cash and cash
equivalents with one financial institution. The Company's sales are primarily to
companies located in the United States and Latin American region. The Company
performs periodic credit evaluations of its customers' financial condition and
does not require

collateral. Accounts receivable are due principally from large U.S. companies
under stated contract terms and the Company provides for estimated credit losses
at the time of sale. Such losses have not been significant to date.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts reported in the supplemental consolidated balance sheets
for cash and cash equivalents, accounts receivable, accounts payable and loan
payable approximate their fair values.

FOREIGN CURRENCY AND INTERNATIONAL OPERATIONS

The functional currency of the Company's active subsidiaries in Argentina,
Brazil, Chile, Spain and Colombia is the local currency. The financial
statements of these subsidiaries are translated to U.S. dollars using period-end
rates of exchange for assets and liabilities, and average rates for the period
for revenues and expenses. Translation gains and losses are deferred and
accumulated as a component of stockholders' equity. The functional currency of
the Company's subsidiaries in highly inflationary economies, Mexico, Uruguay,
and Venezuela, is the U.S. dollar. Accordingly, for those subsidiaries that use
U.S. dollars as the functional currency, monetary assets and liabilities are
translated using the current exchange rate in effect at the period-end date,
while nonmonetary assets and liabilities are translated at historical rates.
Operations are generally translated at the weighted average exchange rate in
effect during the period. The resulting foreign exchange gains and losses are
recorded in the consolidated statement of operations. Revenues earned by the
Company's foreign subsidiaries and assets of such foreign subsidiaries were not
significant for all periods presented or at December 31, 1997, 1998 and June 30,
1999. Commencing January 1, 1999, the functional currency of the Company's
Mexican subsidiary changed from the U.S. dollar to the local currency as Mexico
was no longer considered a hyper-inflationary economy.

COMPREHENSIVE INCOME

The Company reports comprehensive income in accordance with SFAS No. 130,
"Reporting Comprehensive Income". SFAS No. 130 establishes rules for the
reporting and display of comprehensive income and its components. SFAS No. 130
requires foreign currency translation adjustments to be included in other
comprehensive loss.

SEGMENT INFORMATION

The Company discloses information regarding segments in accordance with SFAS No.
131, "Disclosures about Segments of an Enterprise and Related Information." SFAS
No. 131 establishes standards for reporting of financial information about
operating segments in annual financial statements and requires reporting
selected information about operating segments in interim financial reports. The
disclosure of segment information was not required as the Company operates in
only one business segment.

As of and for the period and years ended December 31, 1996, 1997 and 1998 and
June 30, 1999, substantially all of the Company's assets were located in the
U.S. and the Company derived substantially all of its revenue from businesses
located in the U.S.

3. STOCKHOLDERS' (DEFICIT) EQUITY

Between April 30 and May 5, 1999, a group of third party investors purchased an
aggregate of 3,727,272 shares of the Company's common stock at $11 per share, or
approximately $41,000,000, less fees and commissions of $1,640,000 paid by
issuing 149,091 shares of the Company's common stock. These investors are
subject to a one-year restriction on the sale or transfer of such shares, after
which such investors have been granted certain registration rights.

On May 25, 1999, the Company's initial public offering was declared effective by
the SEC. The Company realized proceeds of approximately $110,400,000, net of
underwriting discounts and commissions and related expenses, from the initial
public offering of 8,050,000 shares of its common stock.

On May 26, 1999, the Company issued 1,133,334 shares of its common stock in
connection with the Wass Net merger.

On June 26, 1999, the Company issued 20,000 shares of its common stock in
connection with an acquisition valued at $1,000,000.

During the six months ended June 30, 1999, the Company issued 1,753,636 shares
of its common stock for $2,016,000 in connection with the exercise of stock
options.

REDEEMABLE CONVERTIBLE PREFERRED STOCK

In July 1997, the Company sold 7,330,000 shares of Series A Redeemable
Convertible Preferred Stock (the "Series A Preferred") for $3,665,000, or $.50
per share. In February 1998, the Company sold 8,000,000 shares of Series B
Redeemable Convertible Stock (the "Series B Preferred") for $12,000,000, or

Preferred, Series B Preferred and the Series C Preferred (collectively, the
"Preferred Stock") were convertible into common stock on a one for one basis,
subject to certain anti-dilution provisions, as defined, at any time at the
option of the holder or automatically in the event of a qualified IPO. The
holders of the Preferred Stock were entitled to the number of votes equal to the
number of common shares that could be obtained upon conversion on the date of
the vote and are entitled to a discretionary noncumulative dividend.

3. STOCKHOLDERS' (DEFICIT) EQUITY (CONTINUED)
Upon a liquidation, including any merger or acquisition where the existing
stockholders of the Company own less than 50% of the successor entity, the
holders of the Preferred Stock were entitled to have the Company redeem their
shares at the original price paid per share (the "Original Investment"), plus a
10% cumulative return less any dividends paid.

In the event that the Preferred Stock had not been converted as of December 31,
2004, the holders of the Preferred Stock can elect to have the Company redeem
their Preferred Stock for an amount equal to their original investment plus any
dividends declared but unpaid.

The Preferred Stock were converted into 31,996,667 shares common stocks on a
one-for-one basis, upon the consummation of the IPO. No Preferred Stock
dividends had been declared or paid. At December 31, 1997 and 1998, and at the
date of conversion total cumulative dividends in arrears, that would be payable
upon a liquidation, were approximately $183,000, $4,233,000 and $8,499,000,
respectively.

The Company has recorded issuance costs incurred in connection with the
Preferred Stock as discounts at issuance and accreted the discounts from the
date of issuance through the date of mandatory redemption on December 31, 2004.

CONVERTIBLE SUBORDINATED NOTES

    In January 1998 the Company issued $4,000,000 8% convertible subordinated
notes due at the earlier of the closing of the Series B Preferred financing, or
on July 21, 1998. In August 1998 the Company issued $2,000,000 8% convertible
subordinated notes due at the earlier of the closing of the Series C Preferred
financing or on December 31, 1998. All amounts outstanding were repaid during
1998 in accordance with their terms.

WEBCAST

    As of June 30, 1999 Webcast had 7,237,500 shares of common stock
outstanding. On July 1, 1999 Webcast issued 541,650 shares of Series A Preferred
Stock for $1.80 per share. The Series A Preferred Stock was convertible into
Webcast common stock at $1.80 per share at any time. In connection with the
Webcast Merger, all the outstanding Webcast common stock and Series A Preferred
Stock were exchanged for 842,887 shares of the Company's common stock. (See
Notes 1, 4 and 6).

up to $6,400,000, in the aggregate, due in March 2000, 2001 and 2002 upon the
achievement of certain performance targets (the "Earn-out"), plus related
expenses of approximately $250,000. As a portion of the Earn-out is contingent
upon the continued employment of certain key individuals, the Company will
record a portion of such payments as compensation expense, estimated to be
$3,000,000, when and if such performance targets are met.

SERVICIOS INTERACTIVOS LIMITADA

In June 1999, the Company acquired all the outstanding stock of Servicios
Interactivos Limitada ("SIL") for 20,000 shares of the Company's common stock.

The Company accounted for the aforementioned acquisitions under the purchase
method of accounting and the results of their operations have been included in
the financial statements of the Company from the respective dates of the
acquisitions. The excess purchase price over the fair value of the net assets
acquired, including expenses incurred by the Company, has been recorded as
goodwill. Goodwill resulting from the acquisitions of approximately $7,967,000
is being amortized using the straight-line method over three years.

The pro forma unaudited consolidated results of operations, assuming the
consummation of the KD Sistemas acquisition as of January 1, 1998, are as

6. STOCK OPTIONS

    In January 1997, the Company adopted the 1997 Stock Option Plan and, in July
1998, the Company adopted the 1998 Stock Option Plan (collectively, the "Option
Plans"). The 1997 Stock Option Plan and the 1998 Stock Plan provide for the
authorization of 10,000,000 shares. In February 1999, an additional 7,000,000
shares were reserved for issuance pursuant to the 1998 Stock Option Plan. The
Option Plans provide for the granting of incentive stock options or
non-qualified stock options to purchase common stock to eligible participants.
Options granted under the Option Plan are for periods not to exceed ten years.
In July 1998, approximately 1,400,000 non-qualified options outstanding were
exchanged for incentive stock options having generally equivalent terms as the
non-qualified options.

    Other than options to purchase 2,000,000 and 1,500,000 shares granted in
April and December 1998, respectively, which were immediately vested, options
outstanding under the Option Plans generally vest one-third after the first year
of service and ratably each month over the next two years.

    In connection with the granting of stock options in 1998 and the exchange of
non-qualified options to incentive stock options, the Company recorded deferred
compensation of approximately $19,087,000. In connection with the granting of
stock options in 1999, the Company recorded additional deferred compensation of
approximately $5,955,000. Deferred compensation is being amortized for financial
reporting purposes over the vesting period of the options. The amount recognized
as expense during the year ended December 31, 1998 and the six months ended June
30, 1998 and 1999 amounted to approximately $10,421,000, $3,250,000 and
$3,012,000, respectively.

    Because the determination of fair value of all options granted after the
Company became a public entity will include an expected volatility factor in
addition to the factors described in the preceding paragraph, the above results
may not be representative of future periods. No options were granted subsequent
to the consummation of the IPO through June 30, 1999.

    Shares sold by the underwriters to the public will initially be offered at
the initial price to public set forth on the cover of this prospectus. Any
shares sold by the underwriters to securities dealers may be sold at a discount
of up to $1.06 per share from the initial price to public. Any of those
securities dealers may resell any shares purchased from the underwriters to
other brokers or dealers at a discount of up to $0.10 per share from the initial
price to public. If all the shares are not sold at the initial price to public,
the representatives may change the offering price and the other selling terms.

    StarMedia and certain of its directors, its officers and Chase Venture
Capital Associates, L.P. have agreed with the underwriters not to dispose of or
hedge any of their common stock or securities convertible into or exchangeable
for shares of common stock during the period from the date of this prospectus
continuing through the date

                                      U-1
<PAGE>
90 days after the date of this prospectus, except with the prior written consent
of the representatives. This agreement does not apply to any existing employee
benefit plans. Please see "Shares Eligible for Future Sale" for a discussion of
transfer restrictions relating to StarMedia's outstanding shares of common
stock.

    Thomas Weisel Partners LLC, one of the representatives of the underwriters,
was organized and registered as a broker-dealer in December 1998. Since December
1998, Thomas Weisel Partners has been named as a lead or co-manager of 77 filed
public offerings of equity securities, of which 49 have been completed, and has
acted as a syndicate member in an additional 38 public offerings of equity
securities. Thomas Weisel Partners does not have any material relationship with
StarMedia or any of StarMedia's officers, directors or other controlling
persons, except for its proposed contractual relationship with StarMedia under
the terms of the underwriting agreement to be entered into in connection with
this offering.

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

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

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

    As permitted by Rule 103 under the Exchange Act, underwriters and selling
group members that are market makers ("passive market makers") in the common
stock may make bids for or purchases of common stock in the Nasdaq National
Market until a stabilizing bid has been made. Rule 103 generally provides that:

    - a passive market maker's net daily purchases of the common stock may not
      exceed 30% of its average daily trading volume in such securities for the
      two full consecutive calendar months, or any 60 consecutive days ending
      within the 10 days, immediately preceding the filing date of the
      registration statement of which this prospectus forms a part,

    - a passive market maker may not effect transactions or display bids for
      common stock at a price that exceeds the highest independent bid for the
      common stock by persons who are not passive market makers, and

    - bids made by passive market makers must be identified as such.

    StarMedia estimates that its share of the total expenses of this offering,
excluding underwriting discounts and commissions, will be approximately
$800,000.

share. Goldman, Sachs & Co. received 149,091 shares and agreed with StarMedia
