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 Spanish- and
Portuguese-speaking markets online, including local and regional news, business
and sports. The Company promotes user affinity to the StarMedia community by

rooms, instant messaging and personal homepages.

financial statements and footnotes thereto included in the Company's annual

3. FOREIGN CURRENCY AND INTERNATIONAL OPERATIONS

    The functional currency of the Company's active subsidiaries in Argentina,
Brazil, Chile, Mexico, Spain and Colombia is the local currency in each nation.
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 the highly inflationary economies of
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,
net loss and total assets of the Company's foreign subsidiaries were $7,183,000,
$22,186,000 and $50,295,000, respectively, as of and for the six months ended
June 30, 2000.

    In February 2000, the Company acquired all of the shares of Ola
Turista Ltda. ("Ola Turista"), the owner of Guia SP and Guia RJ, leading culture
and entertainment guides in the cities of Sao Paulo and Rio de Jeneiro in
exchange for 71,524 shares of its common stock and $2,000,000 cash. Ola
Turista's portals provide users in the Sao Paulo and Rio de Janeiro metro areas
searchable listings of restaurants, theaters, nightclubs, cinemas, and sports
events. Other offerings include columns on issues of interest to the region such
as sports, fitness, psychology, and a special teen area. We accounted for this
acquisition under the purchase method of accounting.

    In April 2000, the company acquired all of the outstanding equity interests
of Adnet, a leading search portal and Mexico's largest web directory in exchange
for 469,577 shares of common stock and $5,000,000 in cash. We accounted for this
acquisition under the purchase method of accounting.

                             RESULTS OF OPERATIONS
       FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2000 AND JUNE 30, 1999

REVENUE

    Revenues increased to $13.8 million for the three months ended June 30, 2000
from $3.9 million, for the three months ended June 30, 1999. Revenues increased
to $23.8 million for the six months ended June 30, 2000 from $5.5 million for
the six months ended June 30, 1999. The increase in revenues was primarily due
to an increase in the volume of revenue-producing advertising impressions and
sponsorships. During 2000, we continued to:

    - expand our sales force;

    - increase the number of impressions available on our network;

    - increase our marketing efforts; and

    - expand through acquisitions.

    For the three months ended June 30, 1999 and 2000, no single advertiser
accounted for more than 10% of our revenue. For the three months ended June 30,
1999, our top five advertisers accounted for 31% of our revenue. For the three
months ended June 30, 2000, our top five advertisers accounted for 23% of our
revenue.

    For the six months ended June 30, 1999 and 2000, no single advertiser
accounted for more than 10% of our revenue. For the six months ended June 30,
1999, our top five advertisers accounted for 34% of our revenue. For the six
months ended June 30, 2000, our top five advertisers accounted for 24% of our
revenue.

OPERATING EXPENSES

PRODUCT AND TECHNOLOGY

    Product and technology expenses increased to $19.5 million, or 141% of total
revenues, for the three months ended June 30, 2000, from $6.4 million, or 166%
of total revenues, for the three months ended June 30, 1999. This increase was
primarily due to an increase of approximately $7.3 million in expenses related
to additional staffing levels required to support the StarMedia network and
related systems, increased hosting costs of approximately $1.8 million and
approximately $1.9 million in expenses to enhance the content and features of
the StarMedia network. For the six months ended June 30, 2000, product and
technology expenses increased to $35.4 million, or 148% of total revenues, from
$10.0 million, or 183% of total revenues, for the six months ended June 30,
1999. This increase was primarily due to an increase of approximately
$12.4 million related to staffing levels, approximately $3.5 million to enhance
the content and features of the StarMedia network, increased hosting costs of
approximately $4.9 million and additional costs related to consultants,
contracts, and fees of $1.8 million.

    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.

                                       11
<PAGE>
SALES AND MARKETING

    Sales and marketing expenses increased to $22.3 million, or 162% of total
revenues, for the three months ended June 30, 2000, from $13.3 million, or 342%
of total revenues, for the three months ended June 30, 1999. Sales and marketing
expense increased to $40.9 million, or 172% of total revenues, for the six
months ended June 30, 2000 from $22.9 million, or 419% of total revenues, for
the six months ended June 30, 1999. This increase in sales and marketing
expenses was primarily attributable to higher personnel expenses, including
sales commissions, of approximately $6.1 million, expansion of our advertising,
public relations and other promotional expenditures related to an increase in
our branding campaign of approximately $9.2 million. We expect sales and
marketing expenses will continue to increase in absolute dollars.

GENERAL AND ADMINISTRATIVE

    General and administrative expenses increased to $7.7 million, or 56% of
total revenues, for the three months ended June 30, 2000, from $3.2 million, or
82% of total revenues, for the three months ended June 30, 1999. The increase in
general and administrative expenses was primarily due to additional salary and
related charges of $1.1 million and additional rent and related costs of
$1.6 million to support the growth of our business. General and administrative
expenses increased to $15.8 million, or 66% of total revenues, for the six
months ended June 30, 2000, from $5.6 million, or 103% of total revenues, for
the six months ended June 30, 1999. 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 $3.3 million,
additional rental costs of approximately $3.2 million, additional professional
fees and consulting charges of $1.0 million and additional business taxes and
insurance of $900,000. Non-recurring merger charges of $1.0 million for the
three and six months ended June 30, 1999 were incurred as part of the merger
with WassNet.

    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. 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 $7.3 million, or 53% of
total revenues, for the three months ended June 30, 2000, from $1.2 million, or
30% of total revenues, for the three months ended June 30, 1999. Depreciation
and amortization expenses increased to $11.8 million, or 50% of total revenues,
in the six months ended June 30, 2000 from $1.6 million, or 30% of total
revenues, for the six months ended June 30, 1999. The dollar increases were
primarily attributable to the increase in fixed assets of approximately
$33.2 million in the six months ended June 30, 2000 and $6.1 million during the
six months ended June 30, 1999 and goodwill amortization expense of
$3.7 million and $5.8 million in the three months and six months ended June 30,
2000, respectively, related to acquisitions. We expect that depreciation and
amortization expenses will continue to increase as we build the structure
necessary to improve StarMedia's product and acquire other businesses.

STOCK-BASED COMPENSATION EXPENSE

    Of the cumulative deferred compensation amount, $2.3 million was recorded as
an expense during the six months ended June 30, 2000 and $1.1 million was
recorded as expense in the three months ended June 30, 2000. The unamortized
balance is being amortized over the vesting period for the individual options,
which is typically three years for options issued prior to February 1999 and
four years for options issued thereafter.

                                       12
<PAGE>
INTEREST INCOME, NET

    Interest income, net includes income from our cash and investments. Net
interest income increased from $700,000 in the three months ended June 30, 1999
to $3.0 million for the three months ended June 30, 2000. Net interest income
increased from $1.1 million for the six months ended June 30, 1999 to
$6.1 million for the six months ended June 30, 2000. Interest income increased
as a result of capital raised from the issuance of 3,727,272 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 and the follow-on
public offering of shares of our common stock in October 1999.

                        LIQUIDITY AND CAPITAL RESOURCES

    To date, we have primarily financed our operations through the sale of our
equity securities. At June 30, 2000, we had $169.9 million in cash and cash
equivalents, a decrease of $104.2 million from December 31, 1999.

    In the six months ended June 30, 2000, we used $52.4 million in operating
activities, substantially related to our $79.1 million loss during the period,
which included non-cash activities such as $11.8 million in depreciation and
amortization and $2.3 million in non-cash charges related to stock option grants
and $2.2 million of deferred rent.

    For the six months ended June 30, 2000, we used $54.2 million in investing
activities, including $33.2 million for fixed assets, $12.2 million for
investments and other long-term assets and $7.5 million in connection with
acquisitions and related costs.

    Net cash provided by financing activities were $2.3 million and
$159.2 million for the six months ended June 30, 2000 and 1999, respectively.
Net cash provided by financing activities during the six months ended June 30,
2000 consisted of proceeds from the exercise of stock options and the sale of
stock under our Employee Stock Purchase Plan offset by long-term debt payments.
Net proceeds during the six months ended June 30, 1999 consisted primarily of
proceeds from issuance of common stock.

    We have a $12.0 million credit line for the acquisition of computer
equipment and furniture and fixtures. At June 30, 2000, approximately
$3.2 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 terms of the credit
line requires us to maintain at least $10 million in cash and cash equivalents
at all times.

    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 were
obligated to pay AT&T certain minimum amounts. Subsequently, this agreement has
been assigned to Gratis1 with StarMedia providing AT&T a $2.8 million Letter of
Credit.

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

    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.

                                       13
<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.

                        RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes an accounting and
reporting standards for derivative instruments, including derivative instruments
embedded in other contracts, and for hedging activities. In June 1999, the FASB
issued SFAS No. 137, "Accounting for Derivative Instruments and Hedging
Activities Deferral of Effective Date of FASB Statement No. 133", which deferred
the effective date of SFAS No. 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.

                              IMPACT OF YEAR 2000

    The Company has previously discussed the nature of its plans related to Year
2000 compliance. As a result of those planning efforts, the Company experienced
no significant disruptions in mission critical information technology and
non-information technology systems and believes those systems successfully
responded to the Year 2000 date change. The costs associated with Year 2000
compliance were nominal. The Company is not aware of any material problems
resulting from Year 2000 issues, whether with its internal systems, or the
services of third parties. The Company will continue to monitor its mission
critical computer applications and those of its suppliers and vendors throughout
the year to ensure that any latent Year 2000 matters that may arise are
addressed properly.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INFLATION AND FOREIGN CURRENCY EXCHANGE RATE LOSSES

    To date, our results of operations have not been impacted materially by
inflation in the United States 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, 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, our accounts payable and
operating expenses are denominated in foreign currencies. Therefore, we are
exposed to foreign currency exchange risks. Revenues derived from foreign
currencies, however, 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. We may, however, 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.

MARKET RISK

    Our accounts receivable are subject, in the normal course of business, to
collection risks. We regularly assess these risks and have established policies
and business practices to protect against the adverse effects of collection
risks. As a result, we do not anticipate any material losses in this area.

INTEREST RATE RISK

    Our investments are classified as cash and cash equivalents with original
maturities of three months or less. Therefore, changes in the market's interest
rates do not affect the value of the investments as recorded by us.

                                  RISK FACTORS

          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 from which 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 strategic relationships, and develop new ones;

    --  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.

                                       15
<PAGE>
WE HAVE NEVER MADE MONEY AND EXPECT OUR LOSSES TO CONTINUE.

    We have never been profitable. As of June 30, 2000, we had an accumulated
deficit of approximately $228.4 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 three months ended June 30, 2000, we derived approximately $1.9 million,
or 14% 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 ANNUAL OPERATING RESULTS AS AN INDICATION OF OUR
FUTURE RESULTS BECAUSE THEY ARE SUBJECT TO SIGNIFICANT FLUCTUATIONS.

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

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

    --  our ability to attract and retain users;

    --  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 year-to-year 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.

                                       16
<PAGE>
    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. 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 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 on our network specifically. 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 MAY ADVERSELY AFFECT OUR BUSINESS.

    We have and expect to continue to derive substantially all of our revenues
from 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

                                       17
<PAGE>
earnings, which could have an adverse effect on our stock price. Historically,
volatility in Latin America 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.

IF INTERNET USE IN SPANISH- AND PORTUGUESE-SPEAKING MARKETS DOES NOT GROW, OUR
BUSINESS WILL SUFFER.

    The Internet in 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 by a number of factors,
including:

    --  the cost of Internet access;

    --  concerns about security, reliability, and privacy;

    --  ease of use; and

    --  quality of service.

                                       18
<PAGE>
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.

THE 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 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,
comprises a significant portion of our revenues. To the extent that

                                       19
<PAGE>
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.

THE LOSS OF ONE OF OUR TOP ADVERTISERS COULD SIGNIFICANTLY REDUCE OUR
ADVERTISING REVENUE AND MATERIALLY ADVERSELY AFFECT OUR BUSINESS.

    In the three months ended June 30, 2000, our top 5 advertisers accounted for
approximately 23% of our total revenues. Our top 10 advertisers accounted for
approximately 35% of our total revenues. Our business, financial condition and
results of operations could be materially and adversely affected by the loss of
one or more of our top advertisers.

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, 2000, our advertising sales department
consisted of 77 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.

                                       20
<PAGE>
OUR BUSINESS AND GROWTH WILL SUFFER IF WE ARE UNABLE TO HIRE AND RETAIN KEY
PERSONNEL.

    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. Acquisitions could
result in a number of adverse 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;

    --  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

                                       21
<PAGE>
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 websites and online destinations
targeted to 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
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 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 could adversely
affect our visitor traffic.

                                       22
<PAGE>
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 favorable 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.
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. We maintain regional network operating centers in Brazil
and Argentina. 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 occurrs. 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.

                                       23
<PAGE>
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.

                       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

                                       24
<PAGE>
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:

    --  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.

                                       25
<PAGE>
    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.

                                  OTHER RISKS

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

    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.

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
a substantial percentage 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.
