OVERVIEW

     We are a leading provider of private telecommunications network and
Internet services in Latin America. We offer tailor-made, integrated data, voice
and Internet solutions, with an increasing emphasis on broadband transmission,
for national and multinational companies, financial institutions, governmental
agencies and other business customers. We also offer dedicated Internet services
to Internet service and content providers.


     We have operations in Argentina, Brazil, Colombia, Venezuela, Ecuador,
Mexico and the United States and have recently opened offices in Chile and Peru.
We also provide our services in other countries in Latin America. We currently
provide telecommunications and Internet services through our networks, which
consist of owned fiber optic and wireless links, teleports, earth stations and
leased fiber optic and satellite links. We own and operate 12 metropolitan area
networks in some of the largest cities in Latin America, including Buenos Aires,
Bogota, Caracas and Sao Paulo.


     We are building an extensive pan-Latin American broadband fiber optic
network, which will enhance the services we presently provide and significantly
increase our transmission speed and capacity. Our new network will consist of
long-haul, high capacity fiber optic backbones and metropolitan area fiber optic
and wireless links and will use advanced transmission technologies, including
dense wave division multiplexing, or DWDM, asynchronous transfer mode, or ATM,
and Internet protocol, or IP. We call this new network our Broadband Network. We
already own and operate a long-haul, fiber optic network connecting the cities
of Cali, Medellin and Bogota in Colombia over 698 route kilometers. By December
2000, we expect to have built out our Broadband Network to connect major cities
across Argentina and Brazil.

THE INITIAL PUBLIC OFFERING


     In February 2000, we completed the initial public offering of 11,500,000
shares of our common stock, representing approximately 12.6% of our current
total outstanding common stock, for total proceeds after expenses and
commissions of approximately $180.8 million. In addition, we raised
approximately $48.0 million after expenses through the simultaneous sale,
through a private placement, of 2,850,000 shares of common stock to British
Telecommunications plc, one of our existing stockholders. We refer to this
transaction as the British Telecommunications private placement. We also
exchanged shares of our common stock for minority interests in some of our
subsidiaries, and the holders of our preferred stock converted the preferred
stock into shares of our common stock. We refer to the first of these
transactions as the minority interest roll-ups and the second as the conversion
of our preferred stock.


     Our common stock is quoted on the Nasdaq National Market System under the
symbol "IMPT."

OUR COMPETITIVE STRENGTHS

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

     - strong presence in high growth telecommunications markets in Latin
       America

     - established and growing base of "blue chip" business customers

     - early development of our extensive Broadband Network

     - enduring commitment to superior customer service

                                        5
<PAGE>   6


     - strong equity sponsors, including British Telecommunications and Morgan
       Stanley Dean Witter.


     We also believe that we have differentiated ourselves from our competitors
through our proven historical operating performance. From 1992 to 1999:

     - our business customer base grew from 125 customers in two countries to
       1,745 customers in seven countries

     - property, plant and equipment grew from $47.9 million to $310.3 million

     - total consolidated revenues grew from $20.5 million to $228.5 million

     - EBITDA grew from $7.9 million to $33.9 million

OUR BUSINESS STRATEGY

     We intend to strengthen our market leadership position by:

     - expanding and enhancing our service offerings through our Broadband
       Network

     - focusing on business, government, Internet service provider and
       telecommunications carrier customers in Latin America

     - providing end-to-end seamless solutions over our own network
       infrastructure to assure quality

     - increasing our market share by capitalizing on our pan-Latin American
       presence, one-stop shopping capability, operating experience and regional
       reputation

THE BROADBAND NETWORK

     The Latin American markets in which we operate are expected to experience
compounded annual telecommunications and data services revenue growth of
approximately 14% and 30%, respectively, from 1998 through 2002. We believe that
this forecasted growth, coupled with continued deregulation in Latin America,
will fuel demand for additional broadband capacity. To take advantage of this
demand, we are constructing our Broadband Network, which will enable us to
provide high capacity, high speed telecommunications services across Latin
America. Our Broadband Network will consist of:

     - long-haul, high capacity fiber optic backbones linking major cities in
       Latin America


     - fiber optic local rings and wireless access points within major cities in
       Latin America, including Buenos Aires, Sao Paulo, Rio de Janeiro and
       Bogota


     - capacity on undersea cable systems to provide connections among major
       Latin American cities, as well as global telecommunications connections
       and Internet access

     We believe that our Broadband Network will enable us to:

     - cost-effectively offer more bandwidth-intensive services in the near
       future, including intranet and extranet services

     - substantially reduce our costs for leased satellite capacity and leased
       telecommunications links as a percentage of our net revenues

     - create a high capacity, pan-Latin American Internet backbone

     - offer Latin American companies more efficient access to the U.S. Internet
       backbone

     - continue to provide consistent, high quality service by keeping our
       customer traffic on our network

     Upon completion, we expect that our Broadband Network will have the
capacity to transmit up to 5.7 terabits, or 5.7 trillion bits, of data per
second.

     Nortel Agreements. In September 1999, we executed two agreements with
Nortel Networks Corporation to construct the Broadband Network in Argentina and
Brazil for approximately $265 million. On October 25, 1999, we signed agreements
with Nortel to borrow up to $297 million from Nortel to finance this project and
to purchase related equipment from Nortel.


     Global Crossing Agreement. We have signed an agreement with Global Crossing
Development Co. that contemplates our purchase of at least $46 million in
indefeasible rights of use of capacity on Global Crossing's South American fiber
optic network and on other segments of its networks. These rights should enable
us to interconnect our networks in Argentina and Brazil and other Latin American
markets, while giving us global telecommunications access.


     Following the completion of the Broadband Network in Argentina and Brazil,
we plan to expand our Broadband Network to Colombia and Venezuela.

THE IMPSAT SOLUTION

     Our telecommunications solutions typically consist of combinations of
services from our five service lines:

     - NETWORK SERVICES. We offer our customers a broad range of end-to-end
       network services for their point-to-point and point-to-multipoint
       telecommunications needs, ranging from simple connections to customized
       private telecommunications network solutions.

     - INTERNET SERVICES. We offer backbone and access services to corporate
       customers and Internet service providers, or ISPs. Our Broadband Network
       will allow us to offer these services with higher speeds, greater
       capacity and wider geographic coverage.

     - CARRIER'S CARRIER SERVICES. In the year 2000, we intend to offer dark
       fiber capacity, "lit fiber" services and duct capacity to ISPs and
       telecommunications carriers. These services will include high-bandwidth
       links, co-location services, operation and maintenance services and
       equipment provisioning.

     - TELEPHONY SERVICES. We intend to offer national and international long
       distance services to our corporate customers and resellers. We have a
       license to provide these services in Argentina starting in November 2000
       and expect to be able to provide these services in Brazil in 2004.

     - OTHER SERVICES. We offer transactional services that facilitate the
       e-commerce and e-business initiatives of our customers. We also offer
       information technology services, which include the design, installation
       and integration of intranets, extranets and virtual private data
       networks.

                                  THE EXCHANGE

THE EXCHANGE OFFER.........  We are offering to exchange $300,000,000 in
                             principal amount of our 13 3/4% new notes due
                             February 15, 2005, which have been registered under
                             federal securities laws, for $300,000,000 in
                             principal amount of our outstanding unregistered
                             13 3/4% old notes due February 15, 2005, which we
                             issued on February 16, 2000 in a private placement.
                             Under the terms of the exchange offer, you are
                             entitled to exchange your old notes in the exchange
                             offer for the registered new notes with
                             substantially identical terms. The old notes may be
                             tendered in exchange only in integral multiples of
                             $1,000.

                             In order for your outstanding notes to be
                             exchanged, you must properly tender them prior to
                             the expiration of the exchange offer. All old notes
                             that are validly tendered and not validly withdrawn
                             before the expiration of the exchange offer will be
                             exchanged. We will issue the new notes on or
                             promptly after the expiration of the exchange
                             offer. You should read the discussion under the
                             heading "Description of the New Notes" for further
                             information regarding the new notes.

REGISTRATION RIGHTS
 AGREEMENT.................  We sold the old notes on February 16, 2000 in a
                             private placement. At that time, we signed a
                             registration rights agreement with the initial
                             purchasers of the notes which requires us to
                             conduct this exchange offer.

                             This exchange offer is intended to satisfy those
                             registration rights set forth in the registration
                             rights agreement. After the exchange offer is
                             complete, you will no longer be entitled to
                             registration rights with respect to old notes you
                             do not exchange.

IF YOU FAIL TO EXCHANGE
 YOUR OUTSTANDING NOTES....  If you do not exchange your old notes for new notes
                             in the exchange offer, you will continue to be
                             subject to the restrictions on transfer as provided
                             in the old notes and the indenture governing those
                             notes. In general, you may not offer or sell your
                             outstanding notes unless the offer or sale is
                             registered under the federal securities laws or
                             unless those notes are sold in a transaction exempt
                             from or not subject to the registration
                             requirements of the federal securities laws and
                             applicable state securities laws.

                             York City time, on July 21, 2000, unless we decide

CONDITIONS TO THE EXCHANGE
 OFFER.....................  We may terminate or amend the exchange offer if:

                             - any legal proceeding, government action or other
                               adverse development materially impairs our
                               ability to complete the exchange offer

                             - any SEC rule, regulation or interpretation
                               materially impairs the exchange offer

                             - we have not obtained any necessary governmental
                               approvals with respect to the exchange offer

                             conditions to occur, we cannot assure you that they
                             will not occur.

                      SUMMARY DESCRIPTION OF THE NEW NOTES

     The form and terms of the new notes are the same as the form and terms of
the old notes except that the new notes will be registered under the Securities
Act and, therefore, will not bear legends restricting their transfer and will
not be entitled to further registration under the Securities Act. The new notes
will evidence the same debt as the old notes, and both the old notes and the new
notes are governed by the same indenture.

                                 THE NEW NOTES

SECURITIES OFFERED.........  $300,000,000 aggregate principal amount of Senior
                             Notes due 2005. See "Description of the Notes."

MATURITY...................  February 15, 2005.

INTEREST...................  Interest will be payable in cash on February 15 and
                             August 15 of each year, beginning on August 15,
                             2000.

OPTIONAL REDEMPTION........  We may redeem the notes at any time by paying a
                             "make-whole" premium based on U.S. Treasury rates.
                             In addition, at any time before February 16, 2003,
                             we may redeem up to 35% of the aggregate principal
                             amount of the notes with the proceeds of sales of
                             certain kinds of our capital stock at 113.750% of
                             their principal amount on the redemption date. We
                             may make such redemption only if after such
                             redemption at least 65% of the aggregate principal
                             amount of the notes originally issued remain
                             outstanding. See "Description of the
                             Notes -- Optional Redemption."

CHANGE OF CONTROL..........  Upon a change of control (as defined under
                             "Description of the Notes"), we will be required to
                             make an offer to purchase the notes. The purchase
                             price will equal 101% of the principal amount on
                             their date of purchase plus accrued interest. We
                             may not have sufficient funds available at the time
                             of any change of control to make any required debt
                             payment (including repurchases of the notes).


RANKING....................  The notes will rank equally with all other
                             unsecured, unsubordinated indebtedness of our
                             company. At March 31, 2000, we (on an
                             unconsolidated basis excluding guarantees of
                             indebtedness of our subsidiaries) had approximately
                             $350 million of indebtedness other than the notes.
                             We are a holding company and the notes will be
                             effectively subordinated to all liabilities of our
                             subsidiaries. At March 31, 2000, excluding
                             intercompany payables and the guarantee of our
                             12 1/8% Senior Guaranteed Notes due 2003 by one of
                             our subsidiaries, our subsidiaries had
                             approximately $339.5 million of liabilities,
                             including approximately $170.2 million of
                             indebtedness.


CERTAIN COVENANTS..........  The terms of the notes restrict our ability and the
                             ability of our subsidiaries (as described in
                             "Description of the Notes -- Covenants") to:

                             - incur additional indebtedness

                             - create liens

                             - engage in sale-leaseback transactions

                             - pay dividends or make distributions in respect of
                               capital stock

                             - redeem capital stock

                             - make investments or certain other restricted
                               payments

                                       10
<PAGE>   11

                             - sell assets

                             - issue or sell stock of restricted subsidiaries

                             - enter into transactions with stockholders or
                               affiliates

                             - effect a consolidation or merger


TRANSFER RESTRICTIONS......  The notes are subject to certain restrictions on
                             transfer. See "Transfer Restrictions."



REGISTRATION RIGHTS........  We are obligated to use our best efforts to cause
                             the notes to be registered no later than August 16,
                             2000. If this requirement is not met, then the
                             annual interest rate on the notes will increase by
                             .5% until we have complied with our registration
                             obligations.



                                  RISK FACTORS



     You should read the "Risk Factors" section beginning on page 14 of this
prospectus, as well as other cautionary statements throughout the entire
prospectus, to ensure that you understand the risks associated with the notes.


                                USE OF PROCEEDS

     On February 16, 2000, we issued $300 million principal amount of old notes.
We sold the old notes to a limited number of institutional investors pursuant to
exemptions from the registration requirements of the SEC and applicable state
securities laws. We received proceeds from the offering of the old notes of
approximately $294.1 million after deducting selling discounts and commissions
and expenses of the offering of the old notes. We will use the net proceeds to
make capital expenditures relating to the Broadband Network and for general
corporate purposes. Pending such application, we will invest the net proceeds in
short-term liquid securities.

</TABLE>


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


(1) "EBITDA" is defined as operating income plus depreciation and amortization
    expense. We are presenting EBITDA because some investors use it as a measure
    of a company's ability to service its debt and as a measure of operating
    performance. However, EBITDA is not determined using generally accepted
    accounting principles, and therefore our EBITDA is not necessarily
    comparable to EBITDA of other companies. Investors should not view EBITDA as
    an alternative to cash flows calculated under generally accepted accounting
    principles, which we have also presented. EBITDA is not "free cash flow"
    because it will be used to pay interest expense, and remaining amounts after
    we pay our interest expense will be used to pay taxes and make capital
    expenditures.



(2) The ratio of earnings to fixed charges is computed by dividing operating
    income before fixed charges (other than capitalized interest), by fixed
    charges. Fixed charges consist of interest charges and amortization of debt
    expense and discount or premium related to indebtedness. Our earnings were
    insufficient to cover fixed charges by approximately $9.6 million, $7.1
    million, $2.7 million, $22.5 million, $159.4 million and $35.9 million for
    1995, 1996, 1997, 1998 and 1999 and the three months ended March 31, 2000,
    respectively. On a pro forma basis, our earnings would have been
    insufficient to cover fixed charges by approximately $195.5 million, $24.4
    million and $42.8 million for 1999 and the three months ended March 31, 1999
    and 2000.



(3) Our gross interest expense for 1999 and the three months ended March 31,
    1999 and 2000 exceeded our EBITDA by $29.3 million and $2.9 million and
    $15.8 million. On a pro forma basis our EBITDA would have been insufficient
    to cover gross interest expense by approximately $61.1 million and $13.5
    million and $22.7 million for 1999 and the three months ended March 31, 1999
    and 2000.



(4) Pro forma ratios are presented for 1999 and the three months ended March 31,
    2000 as if the offering of the notes had occurred at the beginning of the
    relevant period. Pro forma ratios do not take into effect any unborrowed
    amounts under the vendor financing agreements that we signed with Nortel.



(5) The ratio of total debt to EBITDA for the three months ended March 31, 1999
    and 2000 assumes annualized EBITDA for those periods.

                                  RISK FACTORS

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

     Our business, financial condition, results of operations and our ability to
make payments on the notes could be materially adversely affected by any of the
following risks.

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

WE HAVE SUBSTANTIAL DEBT AND WE MAY LACK FINANCIAL RESOURCES TO MEET OUR
OBLIGATIONS OR SUPPORT OUR BUSINESS AND OPERATIONS


     As of March 31, 2000, on a consolidated basis, we had approximately $820.2
million of indebtedness, and our stockholder's equity was approximately $367.9
million. In addition, as of May 31, 2000, we have unused commitments from Nortel
of approximately $192.7 million to finance the construction of the Broadband
Network in Argentina and Brazil.



     We had an annual net interest expense of approximately $55.6 million for
1999. At March 31, 2000, our ratio of debt to EBITDA for the prior four quarters
was 29.5 times. Our fixed charges exceeded our earnings by approximately $2.7
million, $22.5 million, and $159.4 million for 1997, 1998 and 1999,
respectively. For the first three months of 2000, our fixed charges exceeded our
earnings by $35.9 million.


     Our high level of indebtedness could have important consequences for the
holders of the notes, including:

     - making it difficult for us to obtain future financing

     - limiting our ability to react to changes in the marketplace

     - a substantial portion of our operating income must be allocated to making
       principal and interest payments

     - we are more indebted than a number of our competitors and this may place
       us at a competitive disadvantage in the future

     Our significant indebtedness could have a material adverse effect on our
business, results of operations and ability to make payments on the notes.

WE MAY BE UNABLE TO RAISE THE ADDITIONAL CAPITAL NECESSARY TO CONTINUE GROWING
OUR BUSINESS

     We will require significant amounts of additional capital to fund:

     - the expansion of our private telecommunications networks, including the
       Broadband Network

     - the refinancing of short term debt

     - net losses

     Continuing to build out the Broadband Network will require significant
amounts of additional capital that is not available in our capital expenditures
budget. We cannot assure you that we will be able to obtain sufficient capital
on acceptable terms to fund the full reach of the Broadband Network. If we fail
to obtain financing, we may have to delay or abandon some or all of our
expansion plans, which could have a material adverse effect on us. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources" for an estimate of our capital
expenditure requirements.

     The exact amount and timing of our future capital requirements will depend
upon many factors, including:

     - the cost, timing and extent of upgrading or expanding our networks and
       services

     - the development of new services

     - our ability to penetrate new markets

                                       14
<PAGE>   15

     - regulatory changes

     - the status of competing services

     - potential acquisitions, investments and strategic alliances

     - our results of operations


     During 1999, our cash flow from operations totaled $3.9 million and capital
expenditures totaled $110.3 million. For the first three months of 2000 our cash
flow from operations totaled $18.1 million, and our capital expenditures totaled
$85.1 million. In addition, as of March 31, 2000, approximately $36.8 million of
our debt was scheduled to mature in 2000, and approximately $783.3 million
thereafter. We have historically incurred substantial amounts of short-term
debt. Although we do not have material commitments for short-term debt, we may
borrow substantial amounts of short-term debt in the future.


     We and our subsidiaries may obtain new capital through subsequent public
and private equity and debt financings. If we incur additional indebtedness, we
may be subject to more restrictive financial covenants. We cannot assure you
that additional financing will be available on acceptable terms or at all. If
unplanned expenditures arise or our estimates of our capital requirements prove
to be inaccurate, we may require additional financing sooner than anticipated
and/or require more than we currently expect.

WE HAVE NO OPERATIONS OR REVENUES AND THE CREDITORS OF OUR SUBSIDIARIES HAVE
PRIOR RIGHTS TO OUR SUBSIDIARIES' ASSETS

     We are a holding company with no business operations of our own. Our assets
consist solely of our interests in our subsidiaries and other equity
investments. We intend to use substantially all of the net proceeds from the
offering of the old notes to make loans and provide additional equity to certain
of our subsidiaries, including our subsidiaries in Argentina and Brazil, so that
they can expand and develop their telecommunications infrastructure.

     We must rely upon debt service payments, dividends and other payments from
our subsidiaries to generate the funds necessary to meet our obligations,
including the payment of principal of and interest on the notes. Our
subsidiaries, however, are legally distinct from us and have no obligation,
contingent or otherwise, to pay amounts due pursuant to the notes. Our
subsidiaries will not guarantee the notes.

     The ability of our subsidiaries to make such payments to us will be subject
to availability of funds, the terms of their own indebtedness and applicable
local laws. These restrictions include withholding taxes that must be paid on
interest payments from our subsidiaries to us and foreign exchange controls. The
maximum withholding tax on interest payments abroad from Argentina, Colombia,
Venezuela, Ecuador, Mexico and Brazil are significant. We have been able to
reduce the applicable withholding tax rates by taking advantage of certain
exemptions and financing structures available to us. The maximum withholding tax
rates on dividends remitted abroad from these countries also are significant.
These rates could change at any time. The laws governing all of our
subsidiaries, except IMPSAT USA, permit companies to pay dividends only out of
positive retained earnings determined in accordance with local generally
accepted accounting principles and also require companies to allocate a minimum
percentage of each year's net income to a legal reserve until the total amount
of those reserves equal a certain percentage of authorized and outstanding
capital stock, and to pay dividends only out of excess income after allocation
of such percentages to legal reserves. As a result of those requirements and in
light of the accumulated net losses incurred to date by IMPSAT Venezuela, IMPSAT
Ecuador, IMPSAT Mexico and IMPSAT Brazil, we do not believe that any of our
subsidiaries other than IMPSAT Argentina and IMPSAT Colombia would be able to
pay dividends to us in the foreseeable future.


     Claims of creditors of our subsidiaries, including trade creditors, will
generally have priority as to the assets of our subsidiaries over our claims and
those of the holders of our indebtedness, including the notes. Accordingly, the
notes will be effectively subordinated to the liabilities including trade
payables, of our subsidiaries. At March 31, 2000, our subsidiaries had
approximately $464.5 million of liabilities (excluding intercompany payables),
including $295.2 million of indebtedness (including guarantees of our 12 1/8%
Senior Guaranteed Notes due 2003).

WE HAVE NOT BEEN OPERATING VERY LONG AND HAVE A HISTORY OF INCURRING LOSSES
WHICH MAY MAKE IT DIFFICULT TO FUND OUR FUTURE OPERATIONS

     We have a limited operating history. We commenced commercial operations in
1990 and have experienced rapid growth, increasing annual revenues from $8.2
million in 1991 to $228.5 million in 1999. We have, however, incurred net losses
in every year except 1994. Our historic rate of growth and expansion may not
continue. In particular, our rates of growth in Argentina and Colombia have
slowed considerably in recent periods. If we do not achieve and sustain
profitability, our ability to respond effectively to market conditions, to make
capital expenditures and to take advantage of business opportunities could be
negatively affected.

     We have recorded net losses of $2.8 million in 1993, $7.4 million in 1995,
$8.5 million in 1996, $7.6 million in 1997, $40.0 million in 1998, and $131.5
million in 1999. In 1994, we recorded net income of $3.0 million.

CONTINUED GROWTH OF OUR BUSINESS DEPENDS UPON OUR ABILITY TO MANAGE EXPANSION
AND DEVELOPMENT EFFECTIVELY

     Our ability to manage our expansion effectively will require us to continue
to implement and improve our operating, financial and accounting systems and to
hire, train and manage new employees. Among other things, the continued
expansion and development of our business will also depend upon our ability to:

     - construct the Broadband Network

     - design and develop integrated private telecommunications networks

     - secure financing

     - install telecommunications infrastructure

     - obtain any required government authorizations

     - evaluate and penetrate potential new markets

     - hire enough qualified employees

In addition, we must perform these tasks in a timely manner, at reasonable costs
and on satisfactory terms and conditions. Failure to effectively manage our
planned expansion could have a material adverse effect on our business, growth,
financial condition, results of operations and ability to make payments on the
notes.

     Our expansion may involve acquiring other companies or assets. These
acquisitions could divert our resources and management attention and require
integration with our existing operations. We cannot assure you that these
acquisitions will be successful. We further cannot assure you that we will be
successful or timely in developing and marketing service enhancements or new
services that respond to technological change, changes in customer requirements
and emerging industry standards.

WE FACE NUMEROUS RISKS THAT COULD ADVERSELY AFFECT THE DEVELOPMENT OF OUR
BROADBAND NETWORK

    DEVELOPING AND BUILDING OUT THE BROADBAND NETWORK MAY HAVE A NEGATIVE IMPACT
    ON OUR RESULTS OF OPERATIONS

     Developing and building out the Broadband Network, which includes the
expansion into new services for our business customers, will involve:

     - regulatory risks, including obtaining the appropriate licenses

     - interconnection difficulties

     - large amounts of capital expenditures


     - competition from large, well-financed international telecommunications
       carriers (such as AT&T Corporation, WorldCom, Inc., Sprint Corporation,
       Telecom Italia, Spain's Telefonica S.A., among others)


     - substantial start-up and marketing costs

     The development and implementation of the Broadband Network may have a
negative impact on our results of operations, at least over the short term. For
example, when we shift our customers from our satellite based networks to our
Broadband Network's terrestrial facilities, our revenues and results of
operations could

                                       16
<PAGE>   17

be adversely affected by the service disruptions and conversion costs (for
example, earth station de-installation expenses) associated with complying with
these requests.

    WE MUST COMPLETE THE BROADBAND NETWORK EFFICIENTLY AND ON SCHEDULE TO
    IMPLEMENT SUCCESSFULLY OUR BUSINESS STRATEGY

     The construction, operation and any upgrading of the Broadband Network is a
significant undertaking. Administrative, technical, operational and other
problems that could arise may be more difficult to address and solve due to its
size and complexity. The Broadband Network may be more costly than planned and
may take longer to complete than we currently estimate. We may be materially
adversely affected as a result of any significant increase in the estimated cost
of the Broadband Network or any significant delay in its anticipated completion.
The successful and timely completion of the Broadband Network will be affected
by a variety of factors, many of which we cannot control, including:

     - our management of costs related to construction of route segments

     - our ability to obtain required licenses, regulatory approvals and
       rights-of-way

     - timely performance by contractors, including Nortel

     - performance of the fiber and equipment used in the Broadband Network

     - our ability to attract and retain qualified personnel

    WE NEED TO OBTAIN AND MAINTAIN THE NECESSARY RIGHTS-OF-WAY FOR THE BROADBAND
    NETWORK

     We have obtained rights-of-way for the long-haul segments of the Broadband
Network in Argentina and Brazil. We also have rights of way covering all of our
proposed metropolitan area rings in Argentina and covering approximately
one-third of our metropolitan area rings in Brazil. We have approximately
one-half of the construction permits needed to complete the Broadband Network in
Argentina and we are in the process of obtaining our construction permits in
Brazil. While we believe that we will obtain all remaining rights-of-way, we
cannot assure you that we will be able to maintain all of our existing rights
and permits or that we will be able to obtain and maintain all additional rights
and permits needed to construct and operate the Broadband Network in accordance
with our plans.

    EXPANSION OF THE BROADBAND NETWORK WILL REQUIRE SUBSTANTIAL ADDITIONAL
    RESOURCES THAT WE MAY NOT HAVE

     We may need to expand and adapt the Broadband Network to respond to:

     - higher than expected growth in the number of our customers

     - increased demands by our existing customers to transmit larger amounts of
       data

     - changes in our customers' service requirements

     - technological advances by our competitors

     We will require substantial additional financial, operational and
managerial resources to expand or adapt the Broadband Network. If we are unable
to expand or adapt the Broadband Network to respond to these developments on a
timely basis and at a commercially reasonable cost, then our business will be
materially adversely affected.

OUR FAILURE TO ACQUIRE, INTEGRATE AND OPERATE NEW TECHNOLOGIES COULD HARM OUR
COMPETITIVE POSITION

     The telecommunications industry is characterized by rapid and significant
technological advancements and the introduction of new products and services. We
do not possess significant intellectual property rights with respect to the
technologies we use and we are dependent on third parties for the development of
and access to new technology. In addition, we generally own the equipment we use
to provide our services and we will own the fiber optic networks, including
switching equipment, that will constitute the Broadband Network. Therefore,
technological changes that render our equipment out of date, less efficient or
more expensive to operate than newer equipment could cause us to incur
substantial increases in capital expenditures to upgrade or replace such
equipment.

                                       17
<PAGE>   18

     We cannot predict the effect on our business of technological changes, such
as changes relating to emerging wireline and wireless transmission technologies
and the use of the Internet for traditional voice, data or other broadband
services. In addition, it is impossible for us to predict with any certainty
which data transmission technology will prove to be the most economic, efficient
or capable of attracting new customers. A reduction in the demand for data
transmission services or a failure by us to obtain and adapt to new technology
in our markets could have a material adverse effect on our ability to compete
successfully.

WE FACE SIGNIFICANT COMPETITION IN LATIN AMERICA

     The private telecommunications network industry in Latin America is highly
competitive and is generally characterized by low barriers to entry. We expect
that competition in the industry will increase substantially. We compete on the
basis of our experience, quality, customer service, range of services offered
and price.

     Recently we have experienced pricing pressure for some of our services in
our more mature markets, and we expect to continue to face pricing pressure. We
may further experience declining operating profit margins as the monopoly public
telephony operators, or PTOs, in the countries in which we operate become more
competitive and place greater emphasis on data telecommunications. In addition,
we expect new competitors to enter our markets.

    PTOS HAVE COMPETITIVE ADVANTAGES IN THE MARKETPLACE

     In most of our markets, our principal competitor is the local PTO or an
affiliate of the local PTO. The PTOs generally have significant competitive
advantages. These advantages generally include:

     - close ties with national regulatory authorities

     - control over connections to local telephone lines

     - ability to subsidize competitive services with revenues generated from
       services they provide on a monopoly basis

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

     For example, our principal competitors in Argentina are Telecom Soluciones
S.A. and Advance Telecomunicaciones S.A., which are data transmission companies
controlled by Telecom Argentina STET-France Telecom S.A. and Telefonica de
Argentina S.A., respectively. Telecom Argentina and Telefonica are the PTOs in
northern and southern Argentina, respectively. Telecom Soluciones and Advance
Telecomunicaciones use the infrastructure of their PTO owners to deliver
services to their customers.

     In the future, the PTOs may devote substantially more resources to the
sale, marketing and provision of services that compete with us, which could have
a material adverse effect on our business, results of operations and financial
condition and ability to make payments on the notes.

    INTERNATIONAL TELECOMMUNICATIONS CARRIERS HAVE GREATER RESOURCES THAN WE DO


     We compete with private operators of VSAT (very small aperture terminal)
networks, other satellite data transmission networks and terrestrial
telecommunications links. We also expect to face competition from large
international telecommunications carriers, such as AT&T, WorldCom and Sprint,
and from other industry participants. While international telecommunications
carriers have focused on long distance telephony services, they may focus on the
private telecommunications network systems segment of the telecommunications
market as deregulation continues. For example, when the Argentine government
permits full competition in long distance telephony, which is expected in
November 2000, these large telecommunications carriers may enter the Argentine
telephony market and provide data transmission services as well. Many of these
potential competitors have substantially greater financial and other resources
than we do. In addition, consolidation of telecommunications companies and the
formation of strategic alliances within the telecommunications industry could
give rise to significant new competitors. For example, AT&T announced in
November 1999 that it planned to form a new company, AT&T Latin America, by
merging the operations of U.S. telecommunications company, FirstCom Corp. and
Brazil-based Netstream, which companies AT&T recently agreed to acquire, and by
acquiring Keytech LD, a local exchange carrier which is licensed to offer
wireless, high-speed internet and other telecommunications services in
Argentina, AT&T Latin America will have


                                       18
<PAGE>   19

assets in Argentina, Brazil, Chile, Colombia and Peru and is expected to expand
into Venezuela. In addition, we face competition from emerging private
telecommunications providers such as MetroRED Telecommunications S.A., Engeredes
S.A. and Diginet S.A. These companies are data transmission service providers
with expanding operations in Argentina and Brazil. If any of our competitors or
potential competitors devote significant additional resources to the provision
of private telecommunications network services to our customers, there could be
a material adverse effect on our business, financial condition and results of
operations and ability to make payments on the notes.

    OUR COMPETITORS COULD TAKE ADVANTAGE OF NEW OR COMPETING TECHNOLOGIES TO OUR
    DETRIMENT

     Although we believe we have the flexibility to act quickly to take
advantage of any significant technological development, new competing
technologies may negatively affect our business. For example, new technologies
such as digital subscriber line, or DSL, can significantly enhance the speed of
traditional copper lines. DSL or other technologies could enable our PTO
competitors to offer new high-speed services without undergoing the expense of
replacing their existing copper networks. Widespread use of DSL in our markets
could have a material adverse effect on our "last mile" advantage. Our private
telecommunications network services may face competition from entities that use
new or emerging voice and data transmission services or technologies which
currently are not widely available in Latin America. Examples of these
technologies are space-based systems dedicated to data distribution services,
generally known as "Little-LEOs" (low earth orbit satellites) and "Broadband"
(Ka-band) systems. Furthermore, competing technologies may gain market and
commercial acceptance. If these technologies are successful, they may provide
significant long-term competition that could have a material adverse effect on
our business, results of operations and financial condition and ability to make
payments on the notes.

OUR EARNINGS WILL DETERIORATE IF WE CANNOT COLLECT ON OUR CUSTOMER ACCOUNTS


     We provide trade credit to our customers in the normal course of business.
At March 31, 2000, approximately 13% of our gross trade accounts receivable were
past due more than six months but less than one year and approximately 15% were
past due more than one year. We recorded a net provision for doubtful accounts
of $1.2 million in the first quarter of 2000 compared to $0.7 million for the
same period in 1999.



     In February, 2000, we reached an agreement with IBM de Argentina for the
settlement of amounts owed to us, for which we received approximately $2.0
million, representing a recovery of 89.7% of the approximately $2.3 million
amount reserved. As a result of the IBM de Argentina recovery, a lower provision
for doubtful accounts was recorded during the period.


     We cannot assure you that difficulties in collecting amounts due from
customers will not have a material adverse effect on our business, results of
operations and financial condition and ability to make payments on the notes.

ECONOMIC AND POLITICAL CONDITIONS IN LATIN AMERICA POSE NUMEROUS RISKS TO OUR
OPERATIONS


     Substantially all of our revenues are derived from operations in Latin
America. During 1999 and the first three months of 2000, we derived
approximately 47.4% and 45.6% of our consolidated net revenues from services
provided by IMPSAT Argentina and approximately 26.7% and 23.5% by IMPSAT
Colombia. We have also established operations in Venezuela, Mexico and Ecuador,
and in 1998 we began operations in Brazil. Other than the United States and
Mexico, each country where we operate has experienced political and economic
instability in recent years. Moreover, as events in the Latin American region
have demonstrated, negative economic or political developments in one country in
the region can lead to or exacerbate economic or political crises elsewhere in
the region. Furthermore, events in recent years in other developing markets have
placed pressures on the stability of the currencies of a number of countries in
Latin America, including Argentina, Brazil, Colombia, Ecuador and Venezuela.
Continued pressures on the local currencies in the countries in which we operate
are likely to have an adverse effect on many of our customers, which could in
turn adversely affect us. Volatility in regional currencies and capital markets
has also had an adverse effect on our ability and that of our customers to gain
access to international capital markets for necessary financing and refinancing.
A lack of international capital sources for emerging market borrowers could have
a material adverse effect on us and many of our customers.


                                       19
<PAGE>   20

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

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


     The instability and volatility in the world financial markets, which began
with the crisis in the markets of Southeast Asia in 1998 and spread to Russia
and Brazil, negatively affected the Argentine economy and financial markets. In
addition to the effects of the economic difficulties experienced in Brazil,
Argentina's largest trading partner, Argentina has experienced a decline in
investor confidence as a result of domestic political and economic developments.
In October 1999, Moody's cut Argentina's long-term foreign currency rating to B1
from Ba3. We are unable to predict the effect of the recession on our business,
financial condition and results of operations or ability to make payments on the
notes. In addition, we cannot assure you that future uncertainties resulting
from the presidential elections will not negatively impact the Argentine
economy, or that the Argentine monetary authorities will continue to support the
existing peso/dollar exchange rate.


     Colombia. Colombia is our second largest market in terms of revenues
generated. Colombia is experiencing its first economic recession in over 50
years, with unemployment over 20%. The Colombian economy began experiencing a
severe economic crisis in 1998. A combination of low international commodity
prices, a decline in global lending to emerging markets, a drop in domestic
consumption and high interest rates have resulted in an economic recession and a
negative economic performance. Preliminary figures indicate that the Colombian
economy contracted in 1999 for the first time in over half a century and that
Colombia's GDP fell by 6% in the first half of 1999. In June of 1999, Colombia's
central bank effectively devalued the Colombian peso by 9% by widening the
foreign exchange band for the peso, and in September 1999, the central bank
discontinued the use of the foreign exchange band and permitted the peso to
float freely against the U.S. dollar. In the third quarter of 1999, citing
Colombia's macroeconomic imbalances and rising levels of government debt,
Moody's Investors Services and Standard & Poor's downgraded the country's credit
rating to below "investment grade." In addition to increasing borrowing costs
for Colombian companies, the impairment of Colombia's credit rating could
further lower investor confidence in that country and compound its economic
difficulties.

     Colombia has experienced periods of violence over the past four decades,
primarily from leftist guerrilla groups, right-wing paramilitary groups and
drug-related activities. Despite the promise of peace negotiations between the
Colombian government and the main left-wing guerrilla group, known as FARC,
offensives by FARC led the Colombian government to cede effective control of
certain portions of the country to guerilla forces, order a curfew in certain
regions of the country and place the military on a heightened state of alert. We
cannot assure you that these matters, individually or cumulatively, will not
materially adversely affect our business, results of operations and financial
condition and ability to make payments on the notes.

     Venezuela. Our operations in Venezuela, which is currently our third
largest market in terms of revenues generated, are expected to grow. The
Venezuelan government exercises significant control over the Venezuelan economy.
This control has included extensive regulation, including foreign exchange and
price controls. In the last 15 years, Venezuela has experienced periods of
recession or slow or negative growth, high inflation, currency devaluations and
limited availability of foreign exchange. Venezuela's ongoing budget deficit,
due in part to the decline in international oil prices in 1998 and the first
half of 1999, has put pressure on the Venezuelan economy. Venezuela has
experienced high levels of inflation during the past decade. The general rate of
inflation, as measured by the consumer price index, was 37.6% in 1997, 29.9% in
1998 and 20.0% in 1999.

     The Venezuelan economy declined by over 7% in 1999. In addition, Venezuela
experienced a period of political uncertainty in 1999 as a result of the actions
of a Constitutional Assembly that was elected to propose a new constitution.
This project is part of a program by Venezuela's recently elected president, Mr.
Hugo Chavez, to reform and amend the Venezuelan political system. In December
1999, a new constitution was
                                       20
<PAGE>   21


approved by national referendum and the Venezuelan Congress was dissolved.
Elections for President, a new unicameral legislature and governorships are
expected to occur in the third quarter of 2000. Mr. Chavez is expected to run
for President in the new elections. The heightened tensions between the
executive branch and the Constitutional Assembly, on the one hand, and the
Venezuelan legislature, on the other hand, and elements of the new constitution,
have made investors reluctant to invest funds in Venezuela. We cannot assure you
that the implementation of a new constitution will not have a material adverse
effect on the Venezuelan economy and our business, results of operations and
prospects in Venezuela.



     Brazil. Although our business in Brazil is currently limited, we expect
Brazil to constitute an increasing share of our business and revenues.
Throughout the 1980s and into the 1990s, the Brazilian economy has suffered from
periods of extremely high rates of inflation and recession. Historically,
Brazil's currency has frequently depreciated in relation to the U.S. dollar. At
the end of 1998, foreign exchange reserves in Brazil had declined to $40 billion
from nearly $70 billion at the end of August 1998. These outflows, which
resulted from the Russian economic crisis (and the subsequent impact on risk
perception of investments in emerging market countries in general) and high
rates of inflation prevailing in the Brazilian economy, put pressure on the
Brazilian real. The Brazilian government permitted the real to float freely
against the U.S. dollar in January 1999. Since that time, the real has devalued
to a low of R$2.17 = $1.00 on March 3, 1999. At May 15, 2000, the real traded at
a rate of R$1.78 = $1.00. We cannot assure you that the real will not again be
devalued relative to the U.S. dollar, or that the real will not fluctuate
significantly relative to the U.S. dollar. A continued downturn in Brazil's
economy could further affect other Latin American countries through the loss of
investor confidence and shocks to intra-regional trade.



     Rapid changes in Brazilian political and economic conditions require us to
continually assess the risks associated with our operations in Brazil and adjust
our business and operating strategy. Although the Brazilian government has had
some success in resolving the economic crisis caused by the devaluation of the
Brazilian real, it will have to overcome internal political resistance to
austerity measures to assure against a recurrence of economic and financial
difficulties. Economic forecasts suggest that the Brazilian economy could
continue to suffer a recession as economic austerity measures and high interest
rates depress consumption and investment. If the Brazilian government fails to
contain the current economic crisis, it could have an adverse material effect on
our business, results of operations and financial condition and ability to make
payments on the notes.


WE ARE VULNERABLE TO CURRENCY FLUCTUATIONS, DEVALUATIONS AND RESTRICTIONS THAT
MAY INCREASE OUR LOSSES AND CAUSE FLUCTUATIONS IN OUR OPERATING RESULTS

     A substantial portion of our costs, including lease payments for satellite
transponder capacity, purchases of capital equipment, and payments of interest
and principal on our indebtedness, is payable in U.S. dollars. To date, we have
not entered into hedging or swap contracts to address currency risks because our
contracts with our customers generally provide for payment in U.S. dollars or
for payment in local currency linked to the exchange rate between the local
currency and the U.S. dollar at the time of invoicing. These contractual
provisions are structured to reduce our risk if currency exchange rates
fluctuate. However, given that the exchange rate is generally set at the date of
invoicing and that in some cases we experience substantial delays in collecting
receivables, we are exposed to exchange rate risk. Pursuant to Brazilian law,
our contracts with customers in Brazil cannot be denominated in dollars or
linked to the exchange rate between the Brazilian real and the U.S. dollar. Our
expansion in Brazil, including our development of the Broadband Network in
Brazil, will therefore increase our exposure to exchange rate risks.

     We are negatively affected by currency devaluations as our customers'
revenues are generally denominated in local currencies. Substantial or continued
devaluations in local currencies relative to the U.S. dollar could have a
material adverse effect on the ability of our customers to absorb the costs of a
devaluation. This could result in our customers seeking to renegotiate their
contracts with us or, failing satisfactory renegotiation, defaulting on or
canceling their contracts. Our competitors and potential future competitors,
including the PTOs and large, multinational telecommunications companies, may be
less exposed to currency risk or may be better able to hedge their currency risk
and could thereby gain a relative competitive advantage in the event of a
currency devaluation. In addition, Latin American economies have experienced
shortages in foreign currency reserves and restrictions on the ability to
expatriate local earnings and convert local currencies into
                                       21
<PAGE>   22


U.S. dollars. Currency devaluations in one country may have adverse effects in
another country. For example, in late 1994 and 1995, several Latin American
countries were adversely affected by the devaluation of the Mexican peso. The
Asian and Russian economic crises had an adverse effect on the financial and
foreign exchange markets of emerging market countries, leading to increased
pressures on local interest rates and currencies, including in Argentina and
Brazil. These pressures, in turn, inhibited the ability of companies operating
in emerging markets to obtain necessary financing and increase prices. Any
devaluation of local currencies in the countries where we operate, or
restrictions on the expatriation of earnings or capital from such countries,
could have a material adverse effect on our business, results of operations and
financial condition and ability to make payments on the notes.


WE FACE REGULATORY RISKS AND UNCERTAINTY WITH RESPECT TO LOCAL LAWS AND
REGULATIONS

     Our business is dependent upon the procurement and maintenance of licenses
to provide various telecommunications network services in the countries in which
we operate. We believe that we have all licenses required for the conduct of our
current operations. We expect that those licenses that are subject to expiration
will be renewed in due course upon our application to the appropriate
authorities. Due to the political and economic risks associated with the
countries in which we operate, we cannot assure you that we will be able to
maintain our licenses in force or that they will be renewed upon their
expiration. The loss, or substantial limitation upon the terms, of our licenses
could have a material adverse effect on our results of operations. For specific
details of our licenses in the various countries in which we operate, including
the expiration date of such licenses, see "Business -- Description of Country
Operations." We cannot assure you that we will succeed in obtaining all
requisite regulatory approvals to operate in those countries in which we may
desire to do business.

     Local laws and regulations differ significantly among the jurisdictions in
which we operate and in which we may operate in the future. The interpretation
and enforcement of these laws and regulations vary and are often based on the
informal views of the local ministries which, in some cases, are subject to
influence by the PTOs. The conditions governing our service offerings may be
altered by future legislation or regulation. We are prohibited by law from
providing international services to or from Argentina during the term of the
monopoly granted to the two international long-distance service providers owned
by Telecom Argentina and Telefonica, unless we obtain the consent of these
entities. This international long-distance monopoly is due to expire in November
2000. In some of our principal existing and target markets, laws and regulations
prohibit or limit the provision of certain telecommunications services.

OUR BUSINESS IS HIGHLY DEPENDENT ON SATELLITE SYSTEMS AND THEY MAY FAIL AND
IMPAIR OUR ABILITY TO PROVIDE SERVICES TO OUR CUSTOMERS

     We currently depend heavily on the integrity, capability and maintenance of
third party controlled satellite systems. The loss or disruption of any facility
or equipment related to these satellite systems, or the interruption of any such
facility's or equipment's transmission capabilities, could have a material
adverse effect on our operations and our ability to provide service to our
customers. Loss or disruption could also cause one or more of our customers to
terminate their contracts with us or fail to renew their contracts. We believe
that the satellite systems upon which we depend are highly reliable. However,
they have in the past and may in the future experience material operational
anomalies and failures. For example, in April 1999, Nahuelsat's Nahuel-1
satellite failed and service to part of our telecommunications networks was lost
for approximately 12 hours.

WE ARE DEPENDENT ON KEY PERSONNEL FOR OUR FUTURE SUCCESS

     Our success depends to a significant degree on members of our senior
management and certain key employees, who generally are not bound by employment
contracts with us, although Mr. Ricardo Verdaguer, our President and Chief
Executive Officer, and Mr. Roberto Vivo, our Deputy Chief Executive Officer,
indirectly hold significant amounts of our stock. Our success also depends in
part upon our ability to hire and retain highly skilled and qualified operating,
marketing, financial and technical personnel. Competition for qualified
employees in the telecommunications industry is intense and, accordingly, we
cannot assure you that we will be able to hire or retain necessary personnel.

                                       22
<PAGE>   23

     In addition, the successful implementation of our Broadband Network will
require us to recruit, hire and retain a significant number of highly skilled
employees. There may be a limited supply of qualified personnel in our countries
of operations.

WE FACE MULTIPLE RISKS ASSOCIATED WITH PROVIDING INTERNET SERVICES


     We offer Internet access to Internet service and content providers and
business and governmental customers. We had $26.6 million in revenues from
Internet services in 1999 and $6.7 million during the first quarter of 2000. In
August 1999, we entered into an agreement with El Sitio, Inc., an Internet
content provider, for the sale of our retail Internet businesses in Argentina,
Brazil and Colombia for approximately $21.5 million. We concluded the sale of
our Argentine and Brazilian retail Internet businesses to El Sitio during the
fourth quarter of 1999 and the sale of our Colombian retail Internet business
during April 2000. See "Certain Relationships and Related Transactions -- El
Sitio." At March 31, 2000, we had over 387 dedicated Internet access corporate
customers.


     As is typical in newer industries, demand and market acceptance remain
unknown factors in the provision of Internet access services. In addition,
critical issues concerning the commercial use of the Internet remain unresolved
and may impact the growth of Internet use. Despite growing interest in the many
commercial uses of the Internet, many businesses in Latin America and elsewhere
have been deterred from purchasing Internet access services. These businesses
have been deterred for a number of reasons, including:

     - inconsistent service

     - lack of cost-effective, high-speed options

     - limited access points

     - inability to integrate business applications on the Internet

     - the need to deal with multiple and frequently incompatible vendors

     - inadequate protection of the confidentiality of stored data and
       information moving across the Internet

     - a lack of tools to simplify Internet access and use

     Published reports have also indicated that capacity constraints caused by
growth in the use of the Internet may, unless resolved, constrain development of
the Internet to the extent that users experience delays, transmission errors and
other difficulties. For example, inadequate transmission infrastructure in Latin
America (such as an insufficiency of telephone lines for Internet access) could
forestall the growth of Internet services in that region. Furthermore, in some
parts of Latin America, the Internet is not seen as an alternative method of
exchanging information or doing business and we cannot guarantee that the
Internet will be widely accepted in the region as an alternative means of
communicating and conducting business. We anticipate the provision of Internet
access services to ISPs will be an important segment of the services available
through our Broadband Network, and the failure of Internet growth in Latin
America could adversely affect our business, results of operations, financial
condition and ability to make payments on the notes.

OUR AFFAIRS AND BUSINESS POLICIES ARE SUBJECT TO CONTROL BY OUR PRINCIPAL
STOCKHOLDERS

     We are a publicly held corporation. Approximately 46.3% of our issued and
outstanding common stock is held by Nevasa Holdings Ltd., 19.8% by Nunsgate
Limited, a wholly owned subsidiary of British Telecommunications, and 5.1% by
the Suramericana Group of Colombia. Nevasa Holdings is a holding company
controlled by the Pescarmona family, Mr. Verdaguer, our President and Chief
Executive Officer, and Mr. Vivo, our Deputy Chief Executive Officer. As a result
of their stock ownership, these stockholders can control our affairs and
business policies, including the election of directors. In addition, 16.3% of
our common stock is held by certain affiliates of Morgan Stanley Dean Witter
(whom we refer to as the Morgan Stanley investors).


THERE IS NO EXISTING PUBLIC TRADING MARKET FOR THE NOTES AND YOUR ABILITY TO
TRANSFER THEM IS LIMITED


     The new notes are being offered to the holders of the old notes. The old
notes were sold by us on February 16, 2000 to a limited number of institutional
investors and are eligible for trading in the Private

                                       23
<PAGE>   24


Offerings, Resale and Trading through Automated Linkages (PORTAL) Market. To the
extent that old notes are tendered and accepted in the exchange offer, the
trading market for the remaining untendered old notes could be adversely
affected. Although we plan to apply to list the new notes on the Luxembourg
Stock Exchange, there is no existing trading market for the new notes. We cannot
assure you of the future development of a market for the new notes, or the
ability of holders of the new notes to sell their new notes or the price at
which such holders may be able to sell their new notes. If such a market were to
develop, the new notes could trade at prices that may be higher or lower than
their principal amount or purchase price, depending on many factors, including
prevailing interest rates, our operating results and the market for similar
securities. Therefore, we cannot give you any assurance as to the liquidity of
any trading market for the new notes or that an active public market for the new
notes will develop. Historically, the market for noninvestment grade debt has
been subject to disruptions that have caused substantial volatility in the
prices of such securities. We cannot assure you that the market for the new
notes will not be subject to similar disruptions. Any such disruptions may have
a significantly adverse effect on your investment in the new notes.

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

OVERVIEW

     We are a leading provider of private telecommunications network and
Internet services in Latin America. We offer tailor-made, integrated data, voice
and Internet solutions, with an increasing emphasis on broadband transmission,
for national and multinational companies, financial institutions, governmental
agencies and other business customers. We also offer dedicated Internet services
to Internet service and content providers.


     We have operations in Argentina, Brazil, Colombia, Venezuela, Ecuador,
Mexico and the United States and have recently opened offices in Chile and Peru.
We also provide our services in other countries in Latin America. We currently
provide telecommunications and Internet services through our networks, which
consist of owned fiber optic and wireless links, teleports, earth stations and
leased fiber optic and satellite links. We own and operate 12 metropolitan area
networks in some of the largest cities in Latin America, including Buenos Aires,
Bogota, Caracas and Sao Paulo.


     We are building our Broadband Network to enhance the services we presently
provide and significantly increase our transmission speed and capacity. This
network will consist of long-haul, high capacity fiber optic backbones and
metropolitan area fiber optic and wireless links and will use advanced
transmission technologies, including DWDM, ATM and IP. We already own and
operate a long-haul, fiber optic network connecting the cities of Cali, Medellin
and Bogota in Colombia over 698 route kilometers and we are constructing an
additional 1,351 route kilometers to close the ring between Cali and Bogota and
to extend this network to reach Barranquilla. By December 2000, we expect to
have built out our Broadband Network to connect major cities across Argentina,
Brazil and Colombia.

     Revenues. We provide services to our customers under contracts which
typically range from six months to five years, but generally are for three
years. The customer generally pays an installation charge at the beginning of
the contract and a monthly fee based on the quantity and type of equipment
installed. Except in Brazil, the fees stipulated in the contracts are generally
denominated in U.S. dollar equivalents. Services (other than installation fees)
are billed on a monthly, predetermined basis, which coincide with the rendering
of the services. We report our revenues net of deductions for sales taxes.

     We have experienced, and anticipate that we will continue to experience,
downward pressure on our prices as we continue to expand our customer base and
as competition for private telecommunications network services grows. When we
have renewed and/or expanded our contracts with existing customers, the prices
we charge have generally declined. As a result, our revenues per unit of
satellite capacity used have been decreasing. In addition, as our business in a
particular country matures, our rate of growth in that country tends to slow. In
particular, this has occurred in Argentina and in Colombia. To compensate for
slower growth in maturing markets, we will seek to provide new services through
our Broadband Network and to expand into new countries.

     Although we believe that our geographic diversification provides some
protection against economic downturns in any particular country, our results of
operations and business prospects are influenced by the overall financial and
economic conditions in Latin America. Many of the countries in which we operate
have experienced political and economic volatility in recent years. With the
exception of the United States and Mexico (which account for only a small
portion of our consolidated revenues), each of the countries in which we operate
experienced economic recession during 1999. In particular, Argentina and
Colombia, our two largest markets in terms of revenues generated, experienced
significant recessions in 1999. These conditions may have material adverse
effects on our business, results of operation and financial condition and
ability to make payments on the notes.

     Costs and Expenses. Our costs and expenses principally include:

     - direct costs

     - salaries and wages

     - selling, general and administrative expenses

     - depreciation and amortization

                                       28
<PAGE>   29


     Our direct costs include payments for leased satellite transponder and
fiber optic capacity. Building the Broadband Network will decrease our payments
for leased capacity as a percentage of revenues. However, there will be some
delay in recognizing cost savings associated with shifting transmission from
leased satellite facilities to our Broadband Network because our satellite
contracts cannot be cancelled before they expire. The other principal items
comprising direct costs are contracted services costs, and other direct costs.
Contracted services costs include costs of maintenance and installation (and
de-installation) services provided by outside contractors. Installation and
de-installation costs are the costs we incur when we install or remove earth
stations, microstations and other equipment from customer premises. Other direct
costs include:


     - Licenses and other fees

     - Sales commissions paid to third-party sales representatives

     - Allowance for doubtful accounts

     Our selling, general and administrative expenses consist principally of:

     - publicity and promotion costs

     - fees and other remuneration

     - travel and entertainment

     - rent

     - plant services and corporate telecommunication and energy expenses

     In connection with the stock options granted on January 5, 2000 under the
1999 Stock Option Plan, we will record approximately $5.4 million in
stockholders' equity as deferred compensation. The deferred compensation will be
amortized to expense over the vesting period, which commences four years after
the date of grant.

     Capacity Transactions. In September 1999, we sold indefeasible rights of
use of telecommunications capacity on segments of the Broadband Network to
Global Crossing for approximately $25 million. We expect to have other similar
transactions in the future. For these transactions, we expect to recognize
revenue and expenses ratably over the term of the indefeasible rights of use
from the date the fiber optic cables are placed in service for the term of the
indefeasible right of use.

     Currency Risks. Except in Brazil, our contracts with customers generally
provide for payment in U.S. dollars or for payment in local currency linked to
the exchange rate between the local currency and the U.S. dollar at the time of
invoicing. Accordingly, inflationary pressures on local economies in the other
countries in which we operate did not have a material effect on our revenues
during 1999. Given that the exchange rate is generally set at the date of
invoicing and that we in some cases experience substantial delays in collecting
receivables, we are exposed to exchange rate risk. Furthermore, under Brazilian
law, our contracts with customers in Brazil cannot be linked to the exchange
rate between the Brazilian real and the U.S. dollar. Our expansion in Brazil
will increase our exposure to exchange rate risks.


     Sale of Retail Internet Business. In August 1999, we entered into an
agreement to sell our retail Internet businesses in Argentina, Brazil and
Colombia to El Sitio, Inc. for approximately $21.5 million. El Sitio provides
Internet content in Latin America. We also agreed to subscribe for $21.5 million
in convertible preferred stock of El Sitio and El Sitio agreed to enter into a
telecommunications services agreement with us to provide services to El Sitio,
including access to the U.S. Internet backbone. We determined that retail
Internet access was not one of our top priorities and was inconsistent with our
emphasis on providing telecommunications services to businesses and governmental
customers, telecommunications carriers and ISPs. We concluded the Brazil
transaction contemplated by the El Sitio Framework Agreement on October 6, 1999,
the Argentina transaction on November 5, 1999, and the Colombia transaction
during April 2000. Upon the consummation of El Sitio's initial public offering
in December 1999, our shares of El Sitio's preferred stock were automatically
converted into 15.4% of El Sitio's then outstanding common stock.

sold to El Sitio were as follows for the periods indicated:

</TABLE>



     Despite the economic recessions experienced in many of our countries of
operation during 1999 and into the first quarter of 2000, we achieved revenue
growth for the first three months of 2000, as compared to the corresponding
period in 1999. This revenue growth was achieved principally because of an
overall increase in the number of customers and services we provided to them
offset, in part, by decreasing prices. Excluding retail Internet and fax store
and forward customers, we had a total of 1,913 customers at March 31, 2000,
compared to 1,534 customers at March 31, 1999. Customer growth was most
pronounced in Brazil, Argentina and the United States. Significant new customers
we obtained during the first quarter of 2000 included IFX, a U.S. Internet
access provider that has commenced operations in Latin America, Banque Nationale
de Paris, and the Buenos Aires Stock Exchange Clearing House in Argentina.



     In August 1999, we entered into an agreement with El Sitio, Inc., an
Internet content provider, for the sale of our retail Internet businesses in
Argentina, Brazil and Colombia for approximately $21.5 million. We concluded the
sale of our Brazilian retail Internet business to El Sitio in October 1999, the
sale of our Argentine retail Internet business to El Sitio in November 1999, and
the sale of our Colombian retail Internet business during April 2000. Our
revenue for the first quarter of 1999 includes $1.6 million from retail Internet


                                       31
<PAGE>   32


business in Argentina, Brazil and Colombia, and our first quarter 2000 revenue
includes $0.2 million from retail Internet business in Colombia.



     The Company's operations in Brazil recorded the highest revenue growth rate
among our countries of operation. Revenues at IMPSAT Brazil during the first
quarter of 2000 totaled $5.1 million, an increase of $4.1 million, or 399.1%,
compared to the same period in 1999. IMPSAT Brazil's revenues for the first
quarter of 2000 included:



     - $1.3 million in wholesale Internet revenues, including revenues from
       Mandic's operations, which were merged into IMPSAT Brazil in October 1999



     - $0.1 million in wholesale Internet revenues from El Sitio, Inc., which
       relates to our telecommunications services used by El Sitio to provide
       Internet access to the retail Internet business we sold to El Sitio in
       October 1999



     Our operations in the United States and Venezuela also showed improved
results. IMPSAT USA's revenues totaled $5.7 million in the first quarter of
2000, a 37.5% increase as compared to the first quarter of 1999. This is
primarily a result of increased network services and Internet backbone access
services to multinational corporations with operations in Latin America. IMPSAT
Venezuela's revenues totaled $6.5 million for the first three months of 2000,
28.8% higher than in the first quarter of 1999.



     In Argentina, revenues for the Company's satellite-based services declined
as compared to the prior year's first quarter while non-satellite-based
services, including terrestrial-based network services and corporate Internet
services, increased.



     Our improved results in Brazil, Venezuela and the United States were offset
by a decrease in revenues at IMPSAT Colombia. During the first quarter of 2000,
our operations in Colombia, our second oldest market, continued to be adversely
affected by that country's economic recession. IMPSAT Colombia's revenues
totaled $13.8 million during the first quarter of 2000, a 7.2% decrease from the
same period in 1999. Due to continuing effects of the recession, we expect
IMPSAT Colombia to continue to experience declining prices and margin pressure
for the remainder of 2000.



     Our revenue for the first quarter of 2000 includes $1.0 million that we
generated from equipment sales during that period, compared to $1.4 million
during the first quarter of 1999.



     Direct Costs.  Our direct costs for the first quarter of 2000 totaled $26.3
million, an increase of $5.8 million, or 28.3%, compared to the first quarter of
1999. Of our total direct costs for the first quarter of 2000, $11.7 million
related to the operations of IMPSAT Argentina and $5.3 million related to the
operations of IMPSAT Colombia. This compares to $9.9 million at IMPSAT Argentina
and $5.1 million at IMPSAT Colombia for the first quarter of 1999. Direct costs
for IMPSAT Brazil totaled $4.0 million for the first quarter of 2000, compared
to $0.7 million for the corresponding period in 1999. Direct costs of our
subsidiaries are described prior to the elimination of intercompany
transactions.



          (1) Contracted Services.  Contracted services costs include costs of
     maintenance and installation (and de-installation) services provided by
     outside contractors. In the first quarter of 2000, our contracted services
     costs totaled $8.1 million, compared to $6.4 million in the first quarter
     of 1999. Of this amount, maintenance costs for our telecommunications
     network infrastructure totaled $5.0 million, compared to $4.2 million
     during the same period in 1999. Our maintenance costs increased because we
     had more infrastructure. In addition, our installation costs totaled $3.1
     million, compared to $2.3 million for the first quarter of 1999. The
     increase in these costs was due in part to a higher number of
     de-installations of VSAT microstations due to customer cancellations and
     customer upgrades to SCPC technology.



          (2) Other Direct Costs.  Other direct costs principally include
     licenses and other fees; sales commissions paid to third-party sales
     representatives; and our allowance for doubtful accounts.



          Sales commissions paid to third-party sales representatives totaled
     $2.1 million, compared to $1.6 million for the corresponding period in
     1999. Most of these commissions related to customers of IMPSAT Argentina.



          We recorded a net provision for doubtful accounts of $1.2 million
     compared to $0.7 million for the same period in 1999. At March 31, 2000
     approximately 13% of our gross trade accounts receivable were

                                       32
<PAGE>   33


     past due more than six months but less than one year and approximately 15%
     were past due more than one year. In February, 2000, we reached an
     agreement with IBM de Argentina for the settlement of amounts owed to us,
     for which we received approximately $2.0 million, representing a recovery
     of 89.7% of the approximately $2.3 million amount reserved. As a result of
     the IBM de Argentina recovery, a lower provision for doubtful accounts was
     recorded during the period.



          (3) Leased Capacity.  Our leased capacity costs totaled $13.0 million,
     which represented an increase of $3.3 million, or 34.1%, from the
     corresponding period in 1999. We had approximately 810 MHz of leased
     satellite capacity at March 31, 2000 and 680 MHz at March 31, 1999. The
     expansion of our satellite capacity was primarily attributable to
     contractually scheduled increases in satellite capacity to match
     anticipated growth in customer demand.



          In addition, to satisfy increasing customer demand for higher
     bandwidth telecommunications links, during the first quarter of 2000 we
     increased our leased dedicated capacity on third-party fiber optic
     networks, spending $3.3 million, compared to $1.6 million for the same
     period in 1999. These costs were incurred principally in Argentina and
     Brazil. Leased fiber optic capacity in Argentina and Brazil is quite
     expensive due to the very limited number of providers. Due to these higher
     costs of leased fiber optic capacity and the continued preference by some
     of our customers for greater bandwidth, we expect our leased capacity costs
     to increase until the scheduled year-end 2000 implementation of the
     Broadband Network in Argentina and Brazil.



          (4) Costs of Equipment Sold.  We incurred costs of equipment sold of
     $0.8 million, compared to $0.9 million in the first quarter of 1999.



     Salaries and Wages.  Salaries and wages totaled $13.0 million, an increase
of $2.2 million, or 20.0%, from the first quarter of 1999. The increase resulted
primarily from:



     - an increase in the number of employees, from 1,088 at March 31, 1999 to
       1,153 at March 31, 2000, particularly in connection with the progression
       of our operations in Brazil, the development of the Broadband Network and
       changes in our corporate staff as a result of our completed initial
       public offering



     - increases in the salaries and wages of our personnel to match market
       rates for personnel with the expertise we require and increases in cost
       of living



     IMPSAT Argentina incurred salaries and wages for the first quarter of 2000
of $5.9 million compared to $4.4 million during the same period in 1999.
Salaries and wages for the first three months of 2000 with respect to IMPSAT
Brazil totaled $2.1 million. IMPSAT Brazil increased its number of employees to
184 persons at March 31, 2000, compared to 134 persons at March 31, 1999, in
connection with our continued development of operations in that country.



     Selling, General and Administrative Expenses.  We incurred SG&A expenses
totaling $13.0 million for the first quarter of 2000, compared to $9.7 million
for the same period in 1999. The increase in SG&A expenses results from:



     - the expansion strategy we have undertaken commencing in the second half
       of 1999, including our development and implementation of our Broadband
       Network and strategy



     - our capital raising efforts in support of our Broadband Network strategy,
       including our initial public offering in February 2000



     Depreciation and Amortization.  Our depreciation and amortization expense
for the first quarter of 2000 totaled $19.9 million, an increase of $9.0
million, or 82.6%, compared to the same period in 1999. The significant increase
in depreciation and amortization expense reflects the our decision at the end of
the third quarter of 1999 to change the depreciable life of some of our customer
premises telecommunications equipment from ten years to five years, as well as
the continued growth in our infrastructure, including the Broadband Network. The
change in our depreciation policy was in response to technological advances in
our industry.


                                       33
<PAGE>   34


     Interest Expense, Net.  Our net interest expense totaled $17.6 million.
This consists of interest expense of $22.4 million and interest income of $4.8
million. Our net interest expense increased $3.2 million, or 22.6%, from net
interest expense for the first quarter of 1999.



     For the first quarter of 2000, the average interest rate on our
indebtedness was 12.2%, compared to an average interest rate of 12.4% for the
corresponding period in 1999. Our total indebtedness as of March 31, 2000 was
$820.2 million, as compared to $484.3 million as of March 31, 1999. We
anticipate that interest expense will increase in the future based on:



     - expected increased levels of borrowing associated with our development of
       the Broadband Network, including the vendor financing agreements that we
       signed with Nortel in October 1999 for a total of up to $297.4 million to
       construct the Broadband Network in Argentina and Brazil



     - the issuance in February 2000 of our 13 3/4 Senior Notes Due 2005



     See "-- Liquidity and Capital Resources."



     Net (Loss) Gain on Foreign Exchange.  We recorded a net gain on foreign
exchange of $2.6 million, compared to a net loss of $6.2 million for the same
period in 1999. The net gain on foreign exchange reflects the appreciation of
the Brazilian real against the U.S. dollar in the first quarter of 2000 compared
to the first quarter of 1999. At March 31, 2000, the exchange rate for the
Brazilian real equaled R$1.75 = $1.00, compared to R$1.81 = $1.00 at December
31, 1999. The rapid devaluation of the real during the first quarter of 1999
upon the decision of the Brazilian government to permit the real to float
against the U.S. dollar has moderated and reversed in recent periods as the
Brazilian economy has improved over the corresponding period.



     Benefit from Income Taxes.  We recorded a benefit from income taxes (all of
which are for foreign taxes) of $0.7 million compared to a benefit for income
taxes of $2.1 million for the first quarter of 1999.



     Net Loss Attributable to Common Stockholders.  For the first quarter of
2000, we incurred a net loss attributable to common stockholders of $29.1
million, an increase of 41.8% compared to $20.5 million for same period in 1999.
The increase in our net loss attributable to common stockholders was principally
due to the change in our depreciation policy discussed above, and an increase in
net interest expense due to higher average outstanding indebtedness.


     1999 COMPARED TO 1998

     General. Our results of operations for 1999 were not as positive as prior
periods for the following principal reasons:


     - the recession in Latin America during 1999, which was the region's most
       severe in decades, accelerated competitive pricing pressures in our more
       mature markets (especially in Argentina and Colombia)



     - higher leased fiber capacity expenses related to increased customer
       demand for high bandwidth telecommunications links


     - the fact that we purchased too much satellite capacity because we did not
       anticipate the breadth of the recession in Latin America

     - expenses of developing the Broadband Network and our Brazilian operations
       (which are in a relatively early stage of development)

     - an increase in our provision for doubtful accounts as a result of changes
       in our provisioning policy, which we discuss further below

     - a change in the depreciable life of some of our customer premises
       telecommunications equipment in view of technological advances in our
       industry


     Revenues. Our net revenues for 1999 totaled $228.5 million, an increase of
$20.4 million, or 9.8%, from net revenues for 1998. Growth in net revenues was
achieved despite a significant economic recession, especially in the countries
where most of our operations are currently deployed (Argentina, Colombia,
Venezuela). In addition to its general adverse effect on revenue and client
growth, the recession in certain cases accelerated pricing pressures existing in
our more mature markets. These conditions could also affect future periods.

</TABLE>

     Our revenue growth for 1999 was attributable to an overall increase in the
number of customers and services we provided to them offset, in part, by
decreasing prices. Excluding Internet and fax store and forward customers, we
had a total of 1,745 customers at December 31, 1999, compared to 1,467 customers
at year end 1998.


     Revenue figures included $8.6 million from retail internet services in
Argentina and Brazil, which were sold to El Sitio, Inc. in the fourth quarter of
1999, and $2.0 million in retail internet services in Colombia that were
transferred to El Sitio in April 2000.


     The recessions in Argentina and Colombia and, to a lesser extent, increased
competition resulted in some of our customers canceling their contracts or
reducing the services we provide to them. For example, our contract in Argentina
with Banco Bansud S.A., one of Argentina's largest private commercial banks and
one of IMPSAT Argentina's top ten customers in 1998, was terminated due to
pricing competition in April 1999. In Colombia, our contracts with six customers
within the Suramericana group were renegotiated during the first quarter of
1999. This renegotiation resulted in an approximately 24% decrease in our prices
under these contracts. Our net revenues from these six companies totaled $2.0
million during 1998. The Suramericana group includes some of our largest
customers in Colombia.


     Our business in Colombia, our second oldest market, was adversely affected
by the severe economic recession experienced during 1999. Due to continuing
effects of the recession, we expect IMPSAT Colombia to continue to experience
declining prices and margin pressure in 2000.


     In addition, revenue growth at IMPSAT Ecuador could decline in coming
periods due to the effects of the continuing economic and political crisis in
that country. Although IMPSAT Ecuador's revenues and revenue growth have not yet
been adversely affected to date by the recession in Ecuador, we cannot predict
the effect of these matters on our results for future periods.

     We completed our first full year of operations in Brazil in 1999. Although
IMPSAT Brazil's expansion of its customer base (90 customers as of December 31,
1999 compared to 48 customers as of the same date in 1998) and operations
continued, adverse economic conditions in Brazil, including the devaluation of
the real against the U.S. dollar, caused IMPSAT Brazil's revenues in U.S. dollar
terms to be lower than expected. Revenues recorded by Mandic during 1999 as
compared to 1998 were also negatively affected by the devaluation of the
Brazilian real against the U.S. dollar during 1999. The real was at
R$1.21 = $1.00 on January 1, 1999 and R$2.10 = $1.00 on December 31, 1999.
                                       35
<PAGE>   36

     On October 5, 1999, we merged Mandic into IMPSAT Brazil, and Mandic ceased
operations. On October 6, 1999, IMPSAT Brazil sold the retail internet business
acquired in the Mandic merger for $12.3 million to O Site Entretenimentos Ltda.,
a subsidiary of El Sitio.

     Direct Costs. Our direct costs for 1999 totaled $105.0 million, an increase
of $37.6 million, or 55.8%, compared to 1998. Of our total direct costs for
1999, $54.4 million related to the operations of IMPSAT Argentina and $20.3
million related to the operations of IMPSAT Colombia. This compares to $32.0
million at IMPSAT Argentina and $17.3 million at IMPSAT Colombia for 1998.
Direct costs for IMPSAT Brazil, which commenced operations towards the end of
the second quarter of 1998, totaled $8.8 million for 1999. Direct costs of our
subsidiaries are described prior to the elimination of intercompany
transactions.

        (1) Contracted Services. Contracted services costs include costs of
        maintenance and installation (and de-installation) services provided by
        outside contractors. In 1999, our contracted services costs totaled
        $26.8 million, compared to $20.5 million in 1998. Of this amount,
        maintenance costs for our telecommunications network infrastructure
        totaled $17.4 million, compared to $12.7 million for 1998. Our
        maintenance costs increased because we had more infrastructure. In
        addition, our installation costs totaled $9.4 million, compared to $7.6
        million for 1998. The increase in these costs was due in part to:

               - private telecommunications network installations completed in
                 1999 in connection with IMPSAT Argentina's contracts to provide
                 private telecommunications network services to the Government
                 of the Province of Buenos Aires and Banco de la Provincia de
                 Buenos Aires

               - a higher number of de-installations of VSAT microstations due
                 to customer cancellations and customer upgrades to SCPC
                 technology

        (2) Other Direct Costs. Other direct costs principally include licenses
        and other fees; sales commissions paid to third-party sales
        representatives; and our allowance for doubtful accounts.

        Sales commissions paid to third-party sales representatives totaled $8.0
        million, compared to $6.8 million for 1998. Most of these commissions
        related to customers of IMPSAT Argentina.


        We recorded a provision for doubtful accounts of $11.2 million compared
        to $5.3 million for 1998. At December 31, 1999, excluding amounts owed
        by two large former customers (ENCOTESA and IBM de Argentina) that were
        the subject of litigation at that date, approximately 19% of our gross
        trade accounts receivable were past due more than six months but less
        than one year and approximately 26% were past due more than one year.
        See "Business -- Legal Matters" for a description of these litigations.



        During the third quarter of 1999, we amended our provisioning policy to
        remove the discretion previously granted to the presidents of our
        operating subsidiaries to override the provisioning of amounts more than
        180 days past due and to reserve 100% of our outstanding receivables due
        from IBM de Argentina. During that quarter we recognized a charge of
        approximately $1.1 million with respect to receivables due from IBM de
        Argentina and additional charges of approximately $4.1 million. In
        addition, at September 30, 1999, we also estimated that the net
        realizable value on the ENCOTESA receivable to be zero, and accordingly
        we recorded an adjustment of $5.1 million relating to this receivable.
        We are continuing to negotiate with ENCOTESA regarding a settlement of
        amounts due in respect of this receivable.


        In addition, due to a general slowdown in the collection of receivables
        in Argentina and some of the other countries in which we operate
        commencing in the second quarter of 1999, which we believe is due to
        economic difficulties experienced in those countries, we added
        approximately $2.5 million to our allowance for doubtful accounts in the
        third quarter of 1999. In particular, our collection of receivables in
        Argentina was adversely affected by the recession in that country during
        1999. IMPSAT Argentina's average days outstanding for net trade
        receivables due was 90 days at December 31, 1999. This represents an
        improvement from IMPSAT Argentina's average days outstanding for net
        trade receivables due of 97 days at June 30, 1999, but a decline from 69
        days at December 31, 1998.

                                       36
<PAGE>   37

        In February, 2000, we reached an agreement with IBM de Argentina for the
        settlement of its receivables due from that company, for which we
        received approximately $2.0 million, representing a recovery of 89.7% of
        the approximately $2.3 million amount reserved.

        (3) Leased Capacity. Our leased capacity costs totaled $44.8 million,
        which represented an increase of $16.1 million, or 56.1%, from the
        corresponding period in 1998. We had approximately 801 MHz of leased
        satellite capacity at December 31, 1999 and 650 MHz at December 31,
        1998.

        The expansion of our satellite capacity was primarily attributable to
        contractually scheduled increases in satellite capacity to match
        anticipated growth in customer demand. A portion of this increase was
        related to the growth in our SCPC services compared to our VSAT
        services. SCPC earth stations use larger amounts of satellite capacity
        than do VSAT microstations. However, we have not needed as much
        satellite capacity as we contracted for, due to adverse economic
        conditions in Latin America. As a result, our satellite capacity cost as
        a percentage of revenues has increased substantially from prior periods.

        In addition, to satisfy increasing customer demand for high bandwidth
        telecommunications links, during 1999, we increased our leased dedicated
        capacity on third-party fiber optic networks in Argentina, spending
        $16.9 million compared to $10.0 million for 1998. Due to this need for
        greater fiber optic bandwidth, we expect our leased capacity costs to
        increase until we implement the Broadband Network. Leased fiber optic
        capacity in Argentina is quite expensive due to the very limited number
        of providers.

        (4) Costs of Equipment Sold. We incurred costs of equipment sold of $5.2
        million, compared to $3.7 million in 1998.

        Salaries and Wages. Salaries and wages totaled $46.2 million, an
        increase of $8.0 million, or 20.9%, from the 1998. The increase resulted
        primarily from:


           - an increase in the number of employees, from 1,029 at December 31,
             1998 to 1,107 at December 31, 1999, particularly in connection with
             the progression of our operations in Brazil and the development of
             the Broadband Network


           - increases in the salaries and wages of our personnel to match
             market rates for personnel with the expertise we require and
             increases in cost of living


        IMPSAT Argentina incurred salaries and wages for 1999 of $19.7 million
        compared to $16.3 million in 1998. Salaries and wages for 1999 relating
        to the Broadband Network totaled $3.0 million. Salaries and wages for
        1999 paid with respect to IMPSAT Brazil and Mandic totaled $4.7 million.
        IMPSAT Brazil increased its number of employees by 60 persons, or 50.4%,
        during 1999 in connection with our development of operations in that
        country.


     Selling, General and Administrative Expenses. We incurred SG&A expenses of
$43.4 million for 1999. SG&A expenses increased $4.7 million, or 12.2%, from
1998.


     The increase in SG&A expenses principally reflects growth in our operations
and the development and implementation of the Broadband Network. For example,
the increase in our expenses for legal, tax and consultancy advice to $8.5
million compared to $7.1 million for 1998 is attributable to the expansion of
our operations, including the financing and development of the Broadband
Network.


     Depreciation and Amortization. Our depreciation and amortization expenses
for 1999 totaled $130.1 million, an increase of $93.1 million, or 252.1%, from
1998. The increase primarily reflected accelerated depreciation resulting from
our decision in the third quarter of 1999 to change the depreciable life of some
of our customer premises telecommunications equipment from 10 years to 5 years
in view of technological advances in our industry.

     Interest Expense, Net. Our net interest expense totaled $55.6 million. This
consists of interest expense of $63.2 million and interest income of $7.4
million. Our net interest expense increased $10.9 million, or 24.3%, from net
interest expense for 1998.


     The increase in our net interest expense reflects higher average
outstanding indebtedness in 1999 compared to 1998 as a result of our issuance in
June 1998 of $225 million principal amount of 12 3/8% Senior

                                       37
<PAGE>   38

Notes due 2008. For 1999, the average interest rate on our indebtedness was
11.3%, compared to an average interest rate of 12.1% for 1998. Our total
indebtedness as of December 31, 1999 was $438.1 million, as compared to $419.7
million as of December 31, 1998. We anticipate that interest expense will
increase in the future based on:

     - expected increased levels of borrowing associated with our development of
       the Broadband Network, including the two financing agreements that we
       signed with Nortel in October 1999 for a total of up to $297.4 million to
       construct the Broadband Network in Argentina and Brazil

     - the issuance of the old notes in February 2000

See "-- Liquidity and Capital Resources."

     Net Loss on Foreign Exchange. We recorded a net loss on foreign exchange of
$8.0 million, compared to a net gain of $0.7 million for 1998. The increase was
principally caused by the devaluation of the Brazilian real against the U.S.
dollar.

     Benefit from (Provision for) Income Taxes. We recorded a benefit from
income taxes (all of which are for foreign taxes) of $20.7 million compared to a
provision for income taxes of $3.8 million for 1998. The increased benefit from
income taxes is attributable to the expected net loss carry-forwards that we
will be able to use in future periods as a result of the accelerated
depreciation expense taken beginning the third quarter of 1999 with respect to
some of our customer premises telecommunications equipment.

     Net Loss Attributable to Common Stockholders. For 1999, we incurred a net
loss attributable to common stockholders of $131.5 million, compared to $34.0
million for 1998.

     1998 COMPARED TO 1997


     Revenues. Revenues for 1998 totaled $208.1 million, compared to $161.1
million for 1997, a $47.0 million increase from revenues for 1997. The following
table shows our revenues by operating subsidiary, including intercompany
amounts, for 1998 and 1997:

</TABLE>

     The increase in IMPSAT Argentina's revenues in 1998 was primarily
attributable to increased revenues from Internet services, as described below.

     Excluding customers of our Internet and our fax store and forward services,
we had a total of 1,467 customers at December 31, 1998, compared to 1,192
customers at December 31, 1997. During 1998, we commenced our operations in
Brazil. At December 31, 1998, IMPSAT Brazil had a total of 48 customers,
compared to 21 customers at the end of the second quarter of 1998.


     Our net revenues in 1998 increased principally from growth in our network
services other than our VSAT based services. For a description of our service
offerings, see "Business -- Existing Network Infrastructure." Revenues from VSAT
services during 1998 totaled $56.7 million, a decrease of $0.7 million, or 1.2%,
from 1997. As a percentage of our net revenues, revenues from VSAT services
declined to 27.3% for 1998 from 35.7% in 1997, reflecting downward pressure on
the prices for our VSAT services. Revenues from Dataplus services for 1998
totaled $45.7 million, an increase of $8.1 million, or 21.6%, from 1997.



     In addition, our revenues from newer network service offerings such as
Minidat increased significantly during 1998. Revenues from Minidat services for
1998 totaled $2.3 million compared to revenues of $17,000 in


                                       38
<PAGE>   39


1997. At December 31, 1998, we had installed 763 Minidat microstations compared
to installations of 119 Minidat microstations at December 31, 1997.


     In 1998, competitive pressures, including lower pricing, resulted in
relatively flat revenues from Argentina's network service offerings. IMPSAT
Argentina's revenues from VSAT and Dataplus services for 1998 totaled $37.6
million and $23.5 million, respectively, an increase of $1.7 million, or 4.7%,
and a decrease of $0.1 million, or 0.6%, from 1997.

     Internet service revenues totaled $21.1 million in 1998, as compared to
$7.7 million for 1997. At December 31, 1998, we had in excess of 79,000 retail
Internet customers and 241 corporate Internet customers, compared to 19,000
retail Internet customers and 45 corporate Internet customers at December 31,
1997. Mandic's net revenues from Internet services in 1998 (after our
acquisition) totaled $8.3 million. IMPSAT Argentina's net revenues from Internet
services in 1998 totaled $6.1 million, an increase of $1.8 million, or 41.4%,
from 1997.

     As part of net revenues, we recorded revenues of $4.7 million from certain
equipment sales in 1998 and $3.1 million in 1997.

     Direct Costs. Our direct costs totaled $67.4 million, an increase of $15.7
million, or 27.4%, from 1997. Of total direct costs for 1998, $32.0 million
related to the operations of IMPSAT Argentina and $17.3 million related to
IMPSAT Colombia (compared to $32.2 million at IMPSAT Argentina and $13.6 million
at IMPSAT Colombia in 1997).

        (1) Contracted Services. Our contracted services costs totaled $20.5
        million, compared to $16.8 million in 1997. Of this amount, our
        maintenance costs totaled $12.7 million, an increase of $6.0 million
        from 1997, and our installation costs totaled $7.6 million, compared to
        $4.7 million in 1997.

        (2) Other Direct Costs. Other direct costs were $14.6 million in 1998,
        compared to $12.5 million in 1997. Of this total, sales commissions paid
        to third party sales representatives equaled $6.8 million, compared to
        $5.7 million in 1997. Sales commissions increased in 1998 as a result of
        new private telecommunications network services contracts that we
        obtained in 1998 through the use of third-party sales representatives.

        Other direct costs also reflected an increase in our provision for
        doubtful accounts. On a company-wide basis, we recorded a provision for
        doubtful accounts of $5.3 million, compared to $3.3 million in 1997, as
        a result of payment arrears experienced by certain customers in
        Argentina, Colombia and Ecuador and our change in policy for
        provisioning doubtful accounts.

        (3) Leased Capacity. Our leased capacity payments totaled $28.7 million,
        an increase of $9.4 million, or 49.0%, from 1997. We had approximately
        650.0 MHz of leased satellite capacity at December 31, 1998 and
        approximately 412.6 MHz at December 31, 1997. The expansion of our
        satellite capacity was primarily attributable to contractually scheduled
        increases in satellite capacity to match anticipated growth in the total
        number of Dataplus earth stations which, because of their greater
        transmission capacity and bandwidth requirements compared to VSAT, use
        larger amounts of satellite capacity.

        (4) Cost of Equipment Sold. We incurred costs of equipment sold of $3.7
        million, compared to $3.1 million in 1997.


     Salaries and Wages. Salaries and wages totaled $38.2 million, an increase
of $9.1 million, or 31.2%, from 1997. We increased the salaries and wages of our
personnel to match market rates and increases in costs of living. The increase
also reflected the acquisitions during the second quarter of 1998 of IMPSAT
Brazil and Mandic, which had 119 and 67 employees, respectively, at December 31,
1998. Salaries and wages paid with respect to IMPSAT Brazil and Mandic for 1998
totaled $3.6 million and $1.1 million, respectively. We maintained a total of
1,029 employees at December 31, 1998, compared to 669 employees at December 31,
1997. Of our total employees at December 31, 1998, 28 individuals were assigned
to the Broadband Network. Salaries and wages for 1998 relating to the Broadband
Network totaled $0.5 million.

     Selling, General and Administrative Expenses. We incurred SG&A expenses of
$38.7 million, an increase of $10.4 million, or 36.9%, compared to 1997. This
increase was principally due to SG&A expenses incurred by our two new
subsidiaries, IMPSAT Brazil and Mandic.

     SG&A expenses at IMPSAT Brazil and Mandic for 1998 totaled $5.6 million and
$2.2 million, respectively. We also incurred SG&A expenses of $1.9 million in
1998 in connection with the Broadband Network.

     Compared to 1997, the increase in our SG&A expenses reflected an increase
in entertainment, advertising and promotion costs to $7.0 million compared to
$2.9 million in 1997 relating to:

     - our expansion of operations into Brazil

     - promotion campaigns for our newer services, including Internet, Conexia
       (electronic HMO benefit verification) and Telecampus (video conference
       distance learning)

     - consultant fees relating to our exploration of a new public image

     - related travel and entertainment expenses

In addition, the increase in our SG&A expenses reflected increased expenses for
legal, tax and consultancy advice ($7.1 million compared to $5.2 million for
1997) with respect to the financing and expansion of our operations, including
the acquisitions of IMPSAT Brazil and Mandic and the development of plans for
the Broadband Network.

     Depreciation and Amortization. Our depreciation and amortization expense
totaled $36.9 million, representing an increase of $8.3 million, or 28.9%,
compared to 1997.

     Interest Expense, Net. Our net interest expense totaled $44.7 million,
consisting of interest expense of $49.4 million and interest income of $4.7
million. Net interest expense for 1998 increased $20.4 million, or 84.2%, from
1997. The increase in net interest expense was primarily attributable to our
increased indebtedness, which increased from $220.1 million as of December 31,
1997 to $419.7 million as of December 31, 1998. This increased indebtedness
related primarily to our 12 3/8% note offering in June 1998. The average
interest rate on our indebtedness for 1998 was 12.1%, compared to 11.9% for
1997.

     Provision for Income Taxes. We recorded a provision for income taxes of
$3.8 million, compared to $5.3 million for 1997. IMPSAT Argentina did not record
a provision for income taxes in 1998, compared to $3.2 million for 1997. This
reduction was attributable to carry-forward losses of Resis S.A., a wholly owned
subsidiary of the company that was merged into IMPSAT Argentina in November
1998, that IMPSAT Argentina used to offset its income tax liability in 1998.

     Net Loss Attributable to Common Stockholders. We incurred a net loss
attributable to common stockholders of $34.0 million, an increase of $26.4
million, compared to 1997. The principal reasons for the increase were:

     - the increase in our provision for doubtful accounts

     - increased interest expense attributable to our increased indebtedness as
       a result of our 12 3/8% note offering

     - the incurrence of a net loss of $7.6 million by IMPSAT Brazil in 1998

     - the effect of accrued dividends of $10.0 million on the preferred stock
       during 1998

LIQUIDITY AND CAPITAL RESOURCES

     We will continue to make significant capital expenditures in the next
several years in connection with the Broadband Network, the further development
of our operations in Brazil and new customer accounts (for which we install our
equipment on customer premises). We also have, and will continue to have,
substantial interest expense.

                                       40
<PAGE>   41


     At March 31, 2000, we had total cash and cash equivalents of $557.5
million. Our cash and cash equivalents relate principally to:



     - unused proceeds from our $300 million 13 3/4 Senior Notes Due 2005
       offering in February 2000



     - unused proceeds of our initial public offering in February 2000 of
       11,500,000 shares of our common stock



     - unused proceeds from our private placement in February 2000 of 2,850,000
       shares of common stock to British Telecommunications plc, one of our
       existing stockholders



     The net proceeds from the offering of our 13 3/4 Senior Notes Due 2005 was
approximately $294.1 million. The net proceeds from our initial public offering
and the British Telecommunications private placement totaled approximately
$228.8 million.



     Our budget contemplates that we will need approximately $246.1 million
during the period from March 31, 2000 (including amounts spent to date) through
the end of 2000 for capital expenditures related to the Broadband Network in
Argentina and Brazil. In October 1999, we executed definitive agreements with
Nortel for long term vendor financing commitments of up to approximately $297
million, which we can use to pay for Nortel's construction of the segments of
our Broadband Network in Argentina and Brazil. In addition, we are negotiating a
vendor financing agreement of approximately $20 million with Lucent
Technologies, Inc. as part of our agreement to purchase Lucent fiber optic cable
for the long-haul portions of the Broadband Network in Argentina.


     We do not have any other commitments regarding financing for the Broadband
Network. As a result, the further expansion and development of the Broadband
Network will depend upon our ability to obtain additional financing. If we are
unable to obtain additional financing, we will not be able to maintain our
levels of growth and market position in any of the countries in which we
operate, which could have a material adverse effect on our results of
operations.


     In addition, we anticipate that we will require approximately $148.2
million for other capital expenditures, including those related to our existing
telecommunications business (including amounts spent to date) through the end of
2000, and significant amounts thereafter.



     In the three months ended March 31, 2000, our operating activities
generated $18.1 million, compared with $6.5 million used during the same period
in 1999. Financing activities, principally our offering of our 13 3/4 Senior
Notes Due 2005, our initial public offering and our private placement of common
stock to British Telecommunications, provided $492.1 million in net cash for the
three months ended March 31, 2000, compared with $1.5 million for the same
period in 1999. During the first quarter of 2000, we used $50.4 million net cash
for investing activities, compared to $17.2 million in the first quarter of
1999.



     At March 31, 2000, we had leased satellite capacity with annual rental
commitments of approximately $33.0 million through the year 2003. In addition,
at March 31, 2000, we had commitments to purchase telecommunications equipment
amounting to approximately $10.0 million.


YEAR 2000

     The year 2000 problem refers to the failure of installed computerized
systems and software products to recognize or accept four digit date entries. In
this case, systems that have date-sensitive features might, for example,
recognize a date using "00" as the year 1900 rather than the year 2000. This
problem could cause malfunctions in certain computer systems, software and
databases with respect to dates on or after January 1, 2000, unless corrected.


     We did not experience any difficulties related to the year 2000 problem on
January 1, 2000 and have not experienced any year 2000 difficulties since that
date. We believe that we have been successful in our efforts to address the year
2000 issue and will, therefore, not suffer any material adverse effect on its
operations or financial condition due to the year 2000 problem. We will,
however, continue to monitor our systems for potential year 2000 difficulties.


                                       41
<PAGE>   42

     We continue to face risks to the extent that the business systems or
products of our suppliers, satellite providers, customers and others with whom
we transact business are not year 2000 compliant. In providing our services, our
systems are required to communicate electronically with customer-owned systems
with respect to a variety of functions. Failure of our customers' systems to be
year 2000 compliant, particularly satellite providers, could impair our ability
to perform these functions. Furthermore, if any of our suppliers cannot provide
us with products, services or systems that meet the year 2000 requirements, our
operating results could be materially adversely affected. We cannot assure you
that the systems of our customers and suppliers will continue to be year 2000
compliant. We could be adversely affected by the year 2000 problem if we or our
suppliers, customers and other businesses have not addressed this issue
successfully.


QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK



     The sections below highlight our exposure to interest rate and foreign
exchange rate risks and change in the market values of our investment in equity
securities. The analyses presented below are illustrative and should not be
viewed as predictive of our future financial performance. Additionally, we
cannot assure you that our actual results in any particular year will not differ
from the amounts indicated below. However, we believe that these results are
reasonable based on our financial instrument portfolio at March 31, 2000 and
assuming that the hypothetical interest rate and foreign exchange rate changes
used in the analyses occurred during year 2000. We do not hold or issue any
market risk sensitive instruments for trading purposes.



     Interest Rate Risk.  Our cash and cash equivalents consist of highly liquid
investments with a maturity of less than three months. As a result of the
short-term nature of the our cash instruments, we do not believe that a
hypothetical 10% change in interest rates would have an impact on our future
earnings and cash flows related to these instruments. A hypothetical 10% change
in interest rates would also have an immaterial impact on the fair values of
these instruments. We are also exposed to interest rate risk on our floating
rate indebtedness, which affects our cost of financing. As of March 31, 2000,
$122.5 million of our long-term debt bears interest at variable rates. Because
these rates are variable, a hypothetical 10% change in interest rates would have
resulted in a related increase or decrease in interest expense of approximately
$61,000 during the first quarter of 2000. The remaining $678.8 million of
long-term debt bears interest at fixed rates. Because these rates are fixed, a
hypothetical 10% change in interest rates would have no material impact on
interest expense or the fair value of these instruments.



     Foreign Currency Risk.  A substantial portion of our costs, including lease
payments for satellite transponder capacity, purchases of capital equipment, and
payments of interest and principal on our indebtedness, is payable in U.S.
dollars. To date, we have not entered into hedging or swap contracts to address
currency risks because our contracts with our customers generally provide for
payment in U.S. dollars or for payment in local currency linked to the exchange
rate between the local currency and the U.S. dollar at the time of invoicing.
These contractual provisions are structured to reduce our risk if currency
exchange rates fluctuate. However, given that the exchange rate is generally set
at the date of invoicing and that in some cases we experience substantial delays
in collecting receivables, we are exposed to exchange rate risk.



     Pursuant to Brazilian law, our contracts with customers in Brazil cannot be
denominated in dollars or linked to the exchange rate between the Brazilian real
and the U.S. dollar. Our expansion in Brazil, including our development of the
Broadband Network in Brazil, has, and will continue to, increase our exposure to
exchange rate risks. Revenues from our Brazilian operations as of December 31,
1999 and March 31, 2000 that are not denominated in the U.S. dollar represented
approximately 3.8% and 8.7% of our total net revenues for 1999 and the first
quarter of 2000, respectively. However, this proportion can be expected to
increase significantly in future periods in connection with the progression of
our operations in Brazil, and the development of the Broadband Network. The
effect of foreign exchange rate fluctuations on our consolidated results in 1999
and the quarter ended March 31, 2000 was not material.



     Changes in Market Value of Investment.  We hold a fair value basis
investment of approximately 15.3% of the common stock of El Sitio, which is
publicly traded on the Nasdaq National Market System. Our investment in El Sitio
is subject to equity price and overall stock market risk. See Note 3 to our
Consolidated Financial Statements. Our El Sitio investment is included in
non-current assets and is accounted for as


                                       42
<PAGE>   43


"available for sale" securities under SFAS No. 115 because our ownership is less
than 20% and we do not have the ability to exercise significant influence over
El Sito's operations.



     Our investment in El Sitio, which is in the Internet industry, is subject
to significant fluctuations in fair market value due to the volatility of the
stock market. A hypothetical 20% decrease in the share price of El Sitio's
common stock from the price at March 31, 2000 would decrease the fair value of
our investment by $26.3 million.



     In the future, we may make additional equity investments in other privately
or publicly held corporations for business and strategic purposes.

                               INDUSTRY OVERVIEW

GENERAL

     The telecommunications industry has recently been undergoing rapid change
due to deregulation, the construction of additional high-bandwidth
infrastructure, the growth of the Internet, the introduction and increasing
adoption of other data intensive applications and the introduction of new
technologies and competition. According to industry sources, the worldwide
telecommunications industry grew by 14.3% per annum from 1989 to 1997 and is
projected to continue to grow at 12% to 18% through the year 2001.

     Deregulation and privatization of telecommunication services, and the
associated onset of competition, have resulted in:

     - the broadening of telecommunications service offerings, including
       advanced and enhanced services (such as voicemail, faxmail, electronic
       mail and Internet applications)

     - lower end-user prices

     These factors have contributed to the increase in worldwide
telecommunications traffic and, specifically, to an even more rapid growth in
data traffic. With our Broadband Network and existing customer relationships, we
believe that we will be well positioned to take advantage of this rapid growth.

THE LATIN AMERICAN TELECOMMUNICATIONS MARKET OPPORTUNITY

     Latin America encompasses some of the largest potential telecommunications
markets in the world. The Latin American markets in which we operate have a
combined:

     - estimated population of 368 million people

     - average GDP per capita of over $4,700

     - estimated compounded annual growth in telephone lines of approximately
       11% through 2002

     - expected compounded annual growth of telecommunications voice service
       minutes of 14% through 2002

     The table below sets forth population, GDP per capita, minutes of outgoing
telecommunications traffic (MTT) and MTT per capita for 1998 for the countries
indicated, according to industry sources:

DEREGULATION

     Latin American telecommunication markets are undergoing significant
deregulation. The countries in Latin America that have or are beginning to
deregulate have done so as their governments have recognized the need to
introduce market competition. Along with many other countries, Argentina,
Brazil, Chile, Colombia, Ecuador, Mexico, Peru and Venezuela have agreed under
the World Trade Organization Agreement on Basic Telecommunications Services to
demonopolize their telecommunications industry within varying time frames that
began in February 1998.

     Argentina's telecommunications sector was privatized in 1990 when Empresa
Nacional de Telecomunicaciones, the then state-owned entity, was split into two
regional monopolies. The Argentine government began demonopolization of the
sector beginning in November 1999 and granted two new licenses that became
operative starting at that time and several others that will be operative in
November 2000. We have been granted one of the licenses that will become
operative in November 2000. In Colombia, the government has

                                       44
<PAGE>   45

awarded two long distance operating licenses to local companies, ending the
monopoly of Colombia's PTO. Similarly, Venezuela has announced the scheduled
demonopolization of its public telephone services by November 2000.

     In July 1998, Brazil privatized its principal PTO, Telebras, and has since
established an independent regulator to oversee its telecommunications industry.
In Mexico, Telefonos de Mexico, S.A. de C.V., the former PTO known as Telmex,
was privatized in 1990, and competitors have been allowed to enter the market
and render long distance services since 1996. In addition, since January 1997,
Telmex has been required to interconnect with the networks of competitors.

INCREASING AVAILABILITY AND DEMAND FOR BROADBAND SERVICES

     In the United States, data service revenues are expected to grow at a
compounded annual rate of approximately 13% through 2002, according to industry
sources. In Latin America, growth in revenues derived from these services is
expected to accelerate and achieve compounded annual growth of approximately 30%
through 2002, assuming relative economic stability is maintained, due to the
following factors:

     - Competition. As competitors enter the Latin American telecommunications
       markets, we expect them to provide an expanded range of
       telecommunications services at competitive prices. We believe that the
       ongoing deregulation of the Latin American telecommunications markets has
       led and will continue to lead to an increase in demand for the more
       sophisticated telecommunications services and solutions. We believe that
       while the incumbent providers in these markets have established customer
       bases, they have not traditionally concentrated on customer service or
       cost efficient operations.

     - Globalization of corporations. As corporations in more developed markets
       expand into growth markets such as Latin America, we believe that the
       need for private network services and broadband capacity between and
       within the major cities in these markets will grow. In addition, as Latin
       American corporations develop into more global enterprises, we believe
       that their need for broadband connections will increase and their
       adoption of bandwidth intensive applications is likely to accelerate.

     - Ongoing development of technologically advanced telecommunications
       infrastructure. Historically, Latin American markets have been dependent
       upon the legacy telecommunications infrastructure of the incumbent
       operators, which is not sufficiently robust to transmit large amounts of
       data traffic. Due to the poor transmission quality of regional
       telecommunications infrastructure, Latin American customers have been
       slower to adopt data intensive applications than similar customers in
       more developed markets such as the United States. We believe that the
       demand for high bandwidth and broadband services will increase as
       infrastructure improves and the use of data intensive applications
       becomes feasible and economical in more markets in Latin America.

     - Increasing worldwide use of the Internet. Technologies such as digital
       subscriber line, or DSL, are driving the adoption of the Internet and
       other data intensive applications in the United States. As Internet use
       increases, corporations are forced to accelerate their adoption of
       additional new technologies and applications, thereby fueling incremental
       demand for broadband services. The Latin American Internet market is,
       according to industry sources, several years behind the market in the
       United States in terms of overall penetration of Internet access and
       Internet related services. Industry sources estimate that the penetration
       rate of web users in the United States was approximately 16% of the U.S.
       population in 1997 and is expected to increase to 40% of the population
       by 2001. The penetration rate of web users in Latin America varies across
       the region but was estimated on average to be 0.8% of the population of
       the Latin American markets in which we operate for 1997 and is forecast
       to reach approximately 4% by 2002. From 1993 to 1998, available data
       indicates that the number of Internet hosts based in the Latin American
       markets in which we operate increased from approximately 7,500 to over
       340,000.

     The Latin American projections that we cite in this prospectus were
published in the last half of 1998 when Latin America was generally in
recession. In contrast, the U.S. growth rates referred to occurred during an
economic expansion. However, we believe that the historical trends in Internet
growth in the U.S. market are broadly indicative of what can be expected to
occur in Latin America.

                                    BUSINESS

OVERVIEW

     We are a leading provider of private telecommunications network and
Internet services in Latin America. We offer tailor-made, integrated data, voice
and Internet solutions, with an increasing emphasis on broadband transmission,
for national and multinational companies, financial institutions, governmental
agencies and other business customers. We also offer Internet services to
Internet service and content providers.


     We have operations in Argentina, Brazil, Colombia, Venezuela, Ecuador,
Mexico, and the United States and have recently opened offices in Chile and
Peru. We also provide our services in other countries in Latin America. We
provide telecommunications and Internet services through our networks, which
consist of owned fiber optic and wireless links, teleports, earth stations and
leased fiber optic and satellite links. We own and operate 12 metropolitan area
networks in some of the largest cities in Latin America, including Buenos Aires,
Bogota, Caracas and Sao Paulo.


     We are building an extensive pan-Latin American broadband fiber optic
network, which will allow us to enhance the services we presently provide and
significantly increase our transmission speed and capacity. Our new network will
consist of long-haul, high capacity fiber optic backbones and metropolitan area
fiber optic and wireless links and will use advanced transmission technologies,
including DWDM, ATM and IP. We already own and operate a long-haul, fiber optic
network connecting the cities of Cali, Medellin and Bogota in Colombia over a
698 route kilometers and we are constructing an additional 1,351 route
kilometers to close the ring between Cali and Bogota to extend this network to
reach Barranquilla. By December 2000, we expect to have built out our Broadband
Network to connect major cities across Argentina and Brazil.


     IMPSAT Fiber Networks, Inc. was organized on August 31, 1994 as a Delaware
holding company to combine the IMPSAT businesses in Argentina, Colombia and
Venezuela. Our operations started in Argentina in 1990 under the name IMPSAT
S.A. (IMPSAT Argentina). We began operations outside of Argentina with the
establishment of IMPSAT Colombia in 1991 and the establishment of IMPSAT
Venezuela in 1992. New operating subsidiaries were created in Ecuador (IMPSAT
Ecuador) and Mexico (IMPSAT Mexico) in 1994, in the United States (IMPSAT USA)
in 1995 and in Brazil (IMPSAT Brazil) in 1998. We have recently opened offices
in Chile and Peru and plan to commence commercial operations in those countries
in the future. In January 2000, we changed our company's name from IMPSAT
Corporation to IMPSAT Fiber Networks, Inc. and on February 4, 2000 we completed
the initial public offering of our common stock and the British
Telecommunications private placement.


OUR COMPETITIVE STRENGTHS

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


     - STRONG PRESENCE IN HIGH GROWTH LATIN AMERICAN TELECOMMUNICATIONS
       MARKETS. We began operations in Argentina in 1990 and have since expanded
       into Colombia, Venezuela, Ecuador, Mexico and Brazil. These markets are
       characterized by emerging economies with less developed
       telecommunications infrastructure. We believe that our experience and
       proven success with operating and growing a competitive
       telecommunications business in these deregulating markets allow us to
       better anticipate future market trends and the needs of our corporate and
       government clients. We also believe that we are well positioned to
       benefit from the forecasted growth in telecommunications needs in Latin
       America and from forecasted worldwide growth in broadband and
       broadband-related telecommunications services. In addition, we are one of
       the few competitive telecommunications companies that has successfully
       competed against the PTOs in Latin America.


     - ESTABLISHED AND GROWING BASE OF "BLUE CHIP" BUSINESS CUSTOMERS. Our early
       penetration of our core Latin American markets provides us with key
       competitive advantages that include industry knowledge and experience,
       name recognition and credibility with customers. As a result, we have
       established a blue chip customer base with numerous large, multinational
       corporations, including YPF/Repsol,

                                       46
<PAGE>   47

       Citibank, Royal Dutch Shell, SmithKline Beecham, Siemens, American
       Express and HSBC, as well as large government entities such as BNA and
       the Government of the Province of Buenos Aires. This customer base has
       grown from 125 in 1992 to 1,745 in 1999. We intend to continue to grow
       with our customers as they expand into other Latin American countries and
       as they increase use of bandwidth-intensive services.

     - EARLY DEVELOPMENT OF OUR EXTENSIVE BROADBAND NETWORK. We possess almost
       all of the authorizations, rights-of-way, easements and governmental
       licenses and permits that we believe are necessary to construct the
       long-haul segments of the Broadband Network in Argentina and Brazil. We
       expect to be equally successful in obtaining these outstanding
       authorizations for our development of the remainder of the local rings
       and last mile segments of the Broadband Network. These regulatory
       processes are time-consuming and we believe we are ahead of competitors
       who are seeking to construct and operate similar networks. We believe
       that this significant time-to-market advantage will enable us to quickly
       establish a leading role in the emerging Latin American market for
       bandwidth intensive data, voice and other transmission solutions.

     - ENDURING COMMITMENT TO SUPERIOR CUSTOMER SERVICE. We view our
       relationships with customers as long-term partnerships in which customer
       satisfaction is of paramount importance. For this reason, we apply an
       integrated approach to our sales, marketing and customer service
       functions. We provide customer service 24 hours a day, 365 days a year.
       We use customer service teams to develop and maintain long-term,
       cooperative relationships with our customers. These relationships provide
       us with an in-depth understanding of our customers' evolving
       telecommunications service requirements and levels of service
       satisfaction. As a result of this approach, we achieve high levels of
       customer satisfaction and are able to identify new revenue generating
       opportunities, customer telecommunications solution enhancements and
       product or service improvements previously overlooked or not adequately
       addressed by the client. We believe that our client service focus is rare
       when compared to many incumbent telecommunications service providers and
       that many customers choose us due to this consultative approach.


     - STRONG EQUITY SPONSORS, INCLUDING BRITISH TELECOMMUNICATIONS AND MORGAN
       STANLEY DEAN WITTER. The Morgan Stanley investors own approximately 16.3%
       and British Telecommunications owns approximately 19.8% of our common
       stock. We believe that the ongoing sponsorship of these investors
       provides us with beneficial strategic advantages as we expand our market
       presence.


     We also believe that we have distinguished ourselves from our competitors
through our proven historical operating performance. From 1992 to 1999:

     - our business customer base grew from 125 customers in two countries to
       1,745 customers in seven countries

     - property, plant and equipment grew from $47.9 million to $310.3 million

     - total consolidated revenues grew from $20.5 million to $228.5 million

     - EBITDA grew from $7.9 million to $33.9 million

BUSINESS STRATEGY

     We intend to maintain and enhance our market leadership position by:

     - EXPANDING AND ENHANCING OUR SERVICE OFFERINGS THROUGH OUR BROADBAND
       NETWORK. We are developing and implementing new service offerings that
       include high-speed Internet access, intranet and extranet service,
       e-commerce and other high-bandwidth broadband telecommunications
       services. We also plan to take advantage of other revenue opportunities
       that we expect to continue to develop as a result of deregulation,
       including domestic long-distance and international switched voice
       telecommunications for our corporate and carrier's carrier customers. We
       are building out the Broadband Network to assist us in these efforts by
       augmenting and complementing our facilities, thereby allowing us to
       provide our customers with a broader array of data intensive
       applications.

                                       47
<PAGE>   48

     - PROVIDING END-TO-END SEAMLESS SOLUTIONS OVER OUR OWN NETWORK
       INFRASTRUCTURE TO ASSURE QUALITY. Since our inception, we have provided
       our services on an end-to-end basis over our networks to ensure quality
       control at both ends and maintain a high level of customer service. We
       seek to continue this operational strategy in the development of our
       Broadband Network, where we will provide both long-haul services and
       last-mile connections through fiber optic and wireless connections. We
       have obtained wireless spectrum in Argentina, Colombia, Venezuela and
       Peru for this purpose.

     - FOCUSING ON BUSINESS, GOVERNMENT, ISP AND TELECOMMUNICATIONS CARRIER
       CUSTOMERS IN LATIN AMERICA. We focus on large national and multinational
       corporate and government end users, for whom reliable data transmission
       is vital. We believe that our superior network quality is especially
       attractive to customers such as these with sophisticated
       telecommunications needs. We also believe that our greater broadband
       capacity and enhanced geographic coverage following the build-out of our
       Broadband Network will be highly attractive to this customer base.

     - INCREASING OUR MARKET SHARE BY CAPITALIZING ON OUR PAN-LATIN AMERICAN
       PRESENCE, ONE-STOP SHOPPING CAPABILITY, OPERATING EXPERIENCE AND REGIONAL
       REPUTATION. We seek to leverage our existing customer base, established
       regional presence, advanced infrastructure and market knowledge to expand
       our operations and service offerings in Latin America. We believe that
       our ability to offer one-stop shopping in Latin America is a key
       competitive advantage. In addition, many of the large national and
       multinational corporations doing business in Latin America demand
       comprehensive telecommunications solutions and increasing amounts of
       bandwidth. We believe that their needs will continue to grow and that our
       established relationships and reputation with these customers will allow
       us to capture an increasing share of their incremental business.
       Additionally, we believe that we are one of the few telecommunications
       service providers in Latin America that can provide the breadth of
       services that we provide on a multinational basis. As an example, we
       provide services in multiple countries to several of our multinational
       customers such as Royal Dutch Shell (Argentina, Colombia and Brazil) and
       Reuters (Argentina, Colombia, Ecuador and Venezuela).

THE BROADBAND NETWORK

     General. The Latin American markets in which we operate are expected to
experience compounded annual telecommunications and data services revenue growth
of approximately 14% and 30%, respectively, from 1998 through 2002. We believe
that this forecasted growth, coupled with continued deregulation in Latin
America, will fuel demand for additional broadband capacity. To take advantage
of this demand, we are constructing the Broadband Network, which will enable us
to provide high capacity, high speed telecommunications services across Latin
America. Our Broadband Network will consist of:

     - long-haul, high capacity fiber optic backbones linking major cities in
       Latin America


     - fiber optic local rings and wireless access points within major cities in
       Latin America, including Buenos Aires, Sao Paulo, Rio de Janeiro and
       Bogota


     - capacity on undersea cable systems to provide connections between major
       Latin American cities, as well as global telecommunications connections
       and Internet access

     We believe that our Broadband Network will enable us to:

     - cost-effectively offer more bandwidth-intensive services in the near
       future, including intranet and extranet services

     - substantially reduce our costs for leased telecommunications links as a
       percentage of our net revenues, over time

     - create a high capacity, pan-Latin American Internet backbone

     - offer Latin American companies more efficient access to the U.S. Internet
       backbone

     - continue to provide consistent, high quality service by keeping our
       customer traffic on our networks

                                       48
<PAGE>   49

     When fully developed and implemented, our Latin American "information
highway" will provide a proprietary fiber optic link among the major cities in
the Latin American countries that we serve, thereby complementing our existing
fiber optic, satellite and wireless networks. Upon completion, we expect that
the long-haul segments of our Broadband Network will have the capacity to
transmit up to 5.7 terabits per second.

     Coverage. By December 2000, we expect the Broadband Network will connect
the principal cities in Argentina and Brazil using fiber optic cable links
complemented by our existing satellite-based networks in Argentina and Brazil.
The Broadband Network will include extensive civil infrastructure in Argentina
and Brazil, including:


     - six ducts along 3,100 route kilometers for the long-haul network in
       Argentina, linking the cities of Buenos Aires, Rosario, Santa Fe,
       Cordoba, San Luis and Mendoza, with one of these ducts containing
       non-zero dispersion fiber, or NZDF, cable (this augments our existing
       fiber optic link between the cities of Buenos Aires and La Plata)



     - three ducts along 1,586 route kilometers for the long-haul network in
       Brazil, linking the cities of Curitiba, Sao Paulo, Belo Horizonte and Rio
       de Janeiro, with one of these ducts containing NZDF cable



     - approximately 320 route kilometers of fiber optic metropolitan area
       backbone and local rings, as well as 3,992 square kilometers of wireless
       coverage, across Buenos Aires, Rosario, Cordoba, La Plata and Mendoza in
       Argentina



     - approximately 688 route kilometers of fiber optic metropolitan area
       backbone and local rings, as well as 1,489 square kilometers of wireless
       coverage, across Sao Paulo, Rio de Janeiro, Belo Horizonte and Curitiba
       in Brazil


     - eight major telehouses (each consisting of infrastructure and equipment
       that form a distribution station within the network) in Buenos Aires,
       Rosario, Cordoba and Mendoza in Argentina and Sao Paulo, Rio de Janeiro,
       Curitiba and Belo Horizonte in Brazil

     In addition to the Broadband Network in Argentina and Brazil, we will
acquire the right to use a duct on the Trans-Andean Crossing System between
Mendoza, Argentina and Valparaiso, Chile as part of our agreements with Global
Crossing. We already own and operate a long-haul fiber optic network connecting
the cities of Cali, Medellin and Bogota in Colombia over 698 route kilometers,
and we are constructing an additional 1,351 route kilometers to close the ring
between Cali and Bogota and to extend this network to reach Barranquilla.

     Nortel Agreements. Nortel has agreed to design and construct the segments
of the Broadband Network in Argentina and Brazil for approximately $265 million.
On September 6, 1999, we executed two turnkey agreements with Nortel to develop:

     - long-haul, high capacity fiber optic backbones linking major cities in
       Argentina and Brazil

     - fiber optic and wireless radio local rings and access points within major
       cities in Argentina and Brazil

     - connections in Argentina and Brazil that will integrate our networks with
       other providers' facilities, including submarine cable systems, and
       provide us with access to global telecommunications links

     Nortel will provide, as part of the turnkey agreements:

     - required equipment and components

     - civil infrastructure design and engineering

     - civil works supervision

     - network infrastructure and configuration planning and engineering

     - formulation of network quality and performance specifications

                                       49
<PAGE>   50

     - compilation of network testing procedures and protocols

     - preparation of network maintenance and operations plans and procedures


     On October 25, 1999 we signed agreements with Nortel to borrow up to $297
million from Nortel to finance this project and to purchase related equipment
from Nortel. At May 31, 2000, we have borrowed $104.7 million from Nortel under
this facility.


     Global Crossing Agreements. On July 27, 1999, we entered into an agreement
with Global Crossing that contemplates our entering into a series of definitive
agreements.

     As part of these arrangements, we expect to purchase from Global Crossing
indefeasible rights of use of capacity valued at not less than $46 million on
any of Global Crossing's fiber optic cable networks worldwide. These rights
should enable us to interconnect our networks and give us global international
access.

     On September 22, 1999, we entered into a definitive agreement with Global
Crossing to construct the terrestrial portion of Global Crossing's South
American network between Las Toninas, Argentina on the Atlantic Ocean and
Valparaiso, Chile on the Pacific Ocean (we call this the Trans-Andean Crossing
System). We commenced construction of the Trans-Andean Crossing System in
September 1999. Global Crossing will pay us approximately $64 million for our
turnkey construction of the Trans-Andean Crossing System, which includes our:

     - construction of three ducts and related facilities over 368 route
       kilometers between Las Toninas and Buenos Aires, Argentina and over 464
       route kilometers between Mendoza, Argentina and Valparaiso, Chile

     - licensing to Global Crossing of one duct on our Broadband Network between
       the cities of Buenos Aires and Mendoza in Argentina


     In addition to the Trans-Andean Crossing System, we will sell co-location
space in our telehouses in Rio de Janeiro and Sao Paulo, Brazil; Bogota,
Colombia; Lima, Peru; and Caracas, Venezuela. Our telehouses will contain
switching, routing and other network co-location equipment owned by us or
lessees of space in our telehouses. We will lease space in our telehouses in
Buenos Aires, Argentina and Santiago, Chile to Global Crossing for its network
operations. We also expect to enter into agreements with Global Crossing
providing for our maintenance of Global Crossing's Trans-Andean Crossing System.



     We have also entered into agreements with Global Crossing to license
indefeasible rights of use on portions of the Broadband Network that we are
constructing in Brazil and Peru that will permit Global Crossing to connect its
submarine cable landing points in those countries to Rio de Janeiro and Sao
Paolo in Brazil and Lima in Peru. We also expect to provide backhaul connections
to Global Crossing in Colombia.


     Technology. The Broadband Network will employ advanced technology,
including:

     - Dense wavelength division multiplexing, which allows a pair of fiber
       optic strands to carry simultaneously multiple signals of different
       wavelengths. This dramatically increases the capacity of each fiber
       strand. For example, this technology will enable the long-haul backbones
       of the Broadband Network to carry up to 16 channels at 10 Gbps per pair
       of fiber strands.

     - High capacity wireless links, which enable point-to-point speeds ranging
       from 2 Mbps to 155 Mbps and point-to-multipoint speeds ranging from 64
       kbps to 4 Mbps using local multipoint distribution services (LMDS)
       technology. These links will connect customers that are outside the fiber
       optic rings or in low-density metropolitan areas along the Broadband
       Network.

     - Internet protocol technologies, which will enable us to offer Internet,
       intranet, extranet and voice services and virtual private data networks.

     - Asynchronous Transfer Mode technology, which will allow us to provide low
       latency switching services and support for multiple telecommunications
       protocols, including traditional time division multiplexing (TDM), frame
       relay and Internet protocol.

THE IMPSAT SOLUTION

     Our comprehensive telecommunications solutions consist of any combination
of our service offerings and will consist of services which we intend to offer
following the completion of the Broadband Network in Argentina and Brazil. We
classify these service offerings into five categories: network services,
Internet services, carrier's carrier services, telephony services and other
services.

     Network Services. We offer our customers a broad range of end-to-end
network service combinations for their point-to-point and point-to-multipoint
telecommunications needs, ranging from simple connections to customized private
network solutions. We will offer our network services over our existing and
planned networks, which are comprised of metropolitan area fiber optic rings and
wireless networks, fiber optic and satellite links.

     - Connection Services. Our customers can purchase leased lines, frame relay
       services, ATM services and Internet protocol digital connection services
       to support their specific transmission requirements. Leased lines are
       typically purchased by customers that constantly transmit large amounts
       of voice, data and video traffic. Frame relay and ATM services are
       typically purchased by customers requiring reliable and rapid
       transmission of variable amounts of voice, data and video traffic. We
       typically offer our leased line connection service from 64 Kbps to 2
       Mbps, and we intend to expand this offering to 155 Mbps of capacity. Our
       frame relay services are typically offered from 64 Kbps to 2 Mbps and we
       intend to offer our ATM services from 2 Mbps to 155 Mbps. In addition, we
       offer digital connections using Internet protocol with interfaces of 10
       Mbps to 100 Mbps as one of our options for local data network solutions.

     - Private Network Services. For customers that require significant
       bandwidth and reliable data transmission between a number of sites, we
       offer customized private networks that consist of various components of
       our networks. We also provide them with a variety of other services
       including network management services, trouble shooting reports, quality
       control and value-added services. Our consultative sales process ensures
       that each private network is designed to meet the evolving specific
       business and systems requirements of each customer. We also offer
       services such as video conferencing and remote learning as part of our
       private network services.


     Internet Services. We have offered Internet access services to corporate
and ISP customers since 1996. These services are offered through our satellite
connections and U.S.-based point of presence that link us to the U.S. Internet
backbone through Sprint Corporation, Intermedia Corporation and UUNet. During
this year, we intend to link our Latin American Internet backbone, as part of
the Broadband Network, to the U.S. Internet through our fiber optic links. We
offer both wholesale and corporate Internet services:


     - Backbone Internet Services. We provide a complete Internet service for
       ISPs, including managed line provisioning for domestic and international
       backbone connections between points of presence, access to our
       co-location sites and server services (e-mail and hosting services),
       telephone lines associated with the pool of modems, roaming, as well as
       the use of our network operation and help desk services.

     - Corporate Internet Services. As part of their total telecommunications
       solution, we currently provide our corporate customers with Internet
       access services including line provisioning, equipment provisioning and
       installation, primary and secondary domain registration and maintenance
       and technical support.

     Carrier's Carrier Services. During this year, we intend to offer dark fiber
capacity, "lit" fiber capacity and duct capacity to ISPs and telecommunications
carriers. Our fiber optic cable will provide customers with reliable, broadband
connections between and among our metropolitan area networks at high speeds.
Customers that choose to purchase "lit" capacity will be able to purchase an
initial amount of capacity (typically 45 Mbps) and increase that capacity on
demand. We also plan to offer co-location services including the rental of
secure space, equipment provisioning and operation and maintenance services.

                                       51
<PAGE>   52

     Telephony Services. Following the completion of our Broadband Network in
Argentina and Brazil, we intend to offer domestic and international long
distance services to corporate customers and resellers. We plan to extend our
offering to include private branch exchange (PBX) and centrex connections, toll
free services and calling card services for our corporate customers. We have a
license to provide these services in Argentina starting in November 2000 and
expect to be able to provide these services in Brazil in 2004.

       Other Services.  We offer information technology solutions and
transactional services designed to facilitate our customer's e-business and
e-commerce needs and optimize our customers' business processes.

     - Information Technology Solutions. As part of our end-to-end solutions, we
       also offer a variety of information technology services, including the
       design, installation and integration of intranets, extranets and virtual
       private data networks, through which our customers can conduct business
       in a secure environment as well as integrate these new systems with their
       legacy telecommunications systems. In addition, we offer an outsourcing
       solution for customers that do not have the technical personnel or choose
       not to operate, manage and maintain their telecommunications systems and
       networks.

     - Transactional Services. Our transactional services are designed to
       facilitate the e-commerce and e-business initiatives of our customers.
       For example, we provide our Conexia service to customers in the
       healthcare sector for HMO membership verification, and we intend to
       expand our service to interconnect healthcare service providers (such as
       doctors, pharmacies, hospitals) to allow online prescription
       authorization for patients. We intend to provide additional
       business-to-business e-commerce solutions, primarily to retail businesses
       and financial institutions that conduct high volumes of transactions with
       their suppliers and business customers and increasingly want to establish
       on-line transaction capabilities.

EXISTING NETWORK INFRASTRUCTURE

     Our existing networks are comprised of satellite, fiber optic cable and
wireless links. We are building our Broadband Network to augment and complement
these existing networks by expanding and enhancing the services we presently
provide. The following describes the components of our existing networks:


     VSAT. We are a pioneer in Latin America in the use of a shared hub. We
operate one of the largest shared hub VSAT networks in Latin America as measured
by the number of microstations installed. The use of a shared hub earth station,
whereby many different customers share a central teleport operated by us, allows
us to reduce the cost of telecommunications services to our customers, which
expands our addressable market to smaller and medium-sized businesses. Typical
VSAT network architecture has several VSAT microstations linked to each other by
a teleport and then linked to terrestrially connected sites by one or more local
Teledatos networks. Each remote VSAT location has a relatively small antenna
(typically ranging from 1.2 to 2.4 meters in diameter) and uses time division
multiple access technology, which enhances the use of satellite capacity by
enabling multiple VSATs to share a single satellite channel. Our VSAT
architecture is integrated into our customer's network, in part through protocol
emulation technology that provides support for various data network protocols,
including ATM and frame relay. At March 31, 2000, we had 4,321 VSAT
microstations installed in Latin America.



     We also provide a lower cost VSAT-based service offering under the Minidat
brand name. Our Minidat services use ultra small aperture terminals, which tend
to be about half the size of VSATs. We established Minidat services to meet the
data transmission requirements of customers operating point of sales systems,
automated teller machines, lottery ticket sales, reservation systems, and
wholesales and inventory control and management systems. At March 31, 2000, we
had a total of 1,961 Minidat microstations installed. Certain of our VSAT
microstations and related technology are supplied to us by Hughes Network
Systems.


                                       52
<PAGE>   53


     Single Channel Per Carrier. SCPC uses a multiplexer to transmit either
through several channels bundled into one terminal or through a single channel
that can be used by a number of different terminals (such as data, facsimile or
video). In addition, an SCPC earth station (which has a larger and more powerful
satellite dish than that of the VSAT) can communicate via satellite to another
SCPC earth station or to a teleport, where the transmission can be integrated
with the Teledatos and VSAT networks. SCPC also offers greater transmission
capacity than do VSATs because SCPC uses dedicated satellite links. We provide
these services domestically under the Dataplus brand name and internationally
under the Interplus brand name. At March 31, 2000, we had a total of 1,040
Dataplus earth stations and 383 Interplus earth stations installed.


     Our major suppliers of SCPC technology include Prodelin Corp., Codan, SSE
Technologies Inc. and Radyne ComStream. Our other equipment suppliers include
Newbridge Networks, Cisco Systems, Inc. and General DataComm, Inc. for time
division multiplexers; ACT Networks Inc. for frame relay multiplexers; Harris
Corporation and Digital Microwave Corporation for radiolink systems; and Ascend
Communications and Alcatel Data Networks for packet switches. We also employ
local companies in each location where we operate for installation and
groundwork services.

     Teleports. A teleport has a relatively large antenna (typically ranging
from 3.8 to 11 meters in diameter) as well as sophisticated radio frequency and
network management equipment. Teleports serve as command centers for VSAT
networks in the host country and are linked to our SCPC installations and
metropolitan area networks. Each teleport contains a radio microwave tower to
transmit and receive transmissions to and from nearby customer locations which
are not connected to our existing metropolitan area networks. We own and operate
teleports in Buenos Aires, Argentina; Sao Paulo, Brazil; Bogota, Colombia;
Caracas, Venezuela; Quito, Ecuador; Mexico City, Mexico; and Florida, United
States. In addition to the teleport in Fort Lauderdale, Florida, which commenced
operations in January 1999, IMPSAT USA operates leased teleport facilities in
New Jersey.

     Regional Teleports. Regional teleports are smaller SCPC-based earth
stations that have antennas ranging from 3.8 to 4.5 meters in diameter. Regional
teleports enable us to extend our network to smaller metropolitan area networks
outside a country's capital via satellite to the teleport in that country.
Customers are connected to a regional teleport through one of our metropolitan
area networks, or by wireless or satellite links. We own and operate regional
teleports in Mendoza, Cordoba, Rosario, Tucuman, Mar del Plata, La Plata and
Neuquen in Argentina; Medellin, Cali and Barranquilla in Colombia; Guayaquil,
Ecuador; and Curitiba, Brazil.

     Metropolitan Area Networks. Our fiber optic and/or wireless metropolitan
area networks provide last mile terrestrial fiber optic and wireless links among
and between points in a metropolitan area and also with other points outside the
metropolitan area network by means of satellite and planned fiber optic
connections. Ground-based wireless systems transmit signals in the form of radio
waves from an antenna on top of a building or a transmission tower and are
suitable for use in local transmission because the reach of the transmission
signal typically is limited to one discrete area. While the primary use of the
metropolitan area networks is for interconnection with our teleports and
regional teleports, we have customers that only use the metropolitan area
networks locally and that are not users of the extended satellite and planned
fiber optic telecommunication system. We provide these services under the
Teledatos brand name.

metropolitan area network:


                      [CHART OF METROPOLITAN AREA NETWORK]

     Our first metropolitan area network was established in Buenos Aires,
Argentina in 1990. Other metropolitan area networks now exist in Cordoba,
Mendoza, Rosario, Mar del Plata and Tucuman, Argentina; Bogota, Medellin and
Cali, Colombia; Caracas, Venezuela; and Curitiba and Sao Paulo, Brazil. Our
metropolitan area networks may consist of leased capacity on existing fiber
optic networks owned and maintained by a local PTO (as is the case in Bogota) or
we may design, engineer and manage the installation of our own fiber optic and
radio wireless network (as is the case in Buenos Aires). We charge a monthly fee
for each connection to the Teledatos network and for the number of connections
to the teleport. At March 31, 2000, there were a total of 8,574 connections in
service in our metropolitan area networks. At that date, we had 137 route
kilometers installed in our owned metropolitan area networks. In addition, we
manage and operate a fiber optic network covering 352 route kilometers in
Bogota, Colombia, pursuant to a joint venture with Empresa de Telecomunicaciones
de Santafe de Bogota, the Colombian PTO that provides local telephone service in
the Bogota region.


     In connection with the build-out of the Broadband Network, we will expand
our current metropolitan area networks in Argentina using high speed fiber optic
and wireless links and will construct additional metropolitan area networks in
other major cities in Brazil, which will feature high speed fiber optic and
wireless links.


     Unidirectional Teleport-to-VSAT Network. A unidirectional network typically
consists of the teleport and numerous receive-only, remote VSAT terminals. We
market this service under the Difusat brand name. The source of the information
to be broadcast is generally connected to the teleport through a Teledatos
network. The teleport transmits the information to the VSAT receptors via
satellite. At March 31, 2000, we had installed 350 unidirectional microstations
for use in our Difusat service.



     Undersea Fiber Optic Capacity. We are a member of the Americas-1 and
Columbus-II undersea fiber optic cable consortia and have purchased an initial
total capacity of 2 Mbps on each system for use in our


                                       54
<PAGE>   55

Interplus service. Americas-1, which commenced commercial operation in December
1994, is a 4,960 mile fiber optic cable system connecting Vero Beach, Florida
with the U.S. Virgin Islands, Trinidad, Brazil and Venezuela. Columbus-II links
Mexico, the United States, the U.S. Virgin Islands, Spain, Portugal and Italy
with about 7,440 miles of fiber optic cable.


     As part of the Broadband Network, we intend to secure additional submarine
network capacity linking our metropolitan area networks to points
internationally. We expect to purchase of indefeasible rights of use of capacity
valued at not less than $46 million on any of Global Crossing's undersea digital
fiber optic cable systems (and associated terrestrial capacity) worldwide,
including Global Crossing's South American network. Global Crossing's South
American network, which is currently under development, is an 18,000 km undersea
and terrestrial fiber optic network that will encircle that continent. We have
agreed to construct the terrestrial portion of the South American network
pursuant to a turnkey construction agreement with Global Crossing.


     While undersea capacity to Latin America is scarce at this time, a number
of cables are being developed to satisfy the increasing demand for broadband
capacity. In addition to Global Crossing, we have reserved up to 18 Mbps, 4 Mbps
and 24 Mbps of capacity on the Americas-II, Pan American and Arcos I undersea
fiber optic cable networks, respectively. The Americas-II submarine cable, which
is under development, will connect St. Croix, Puerto Rico, Curacao, Venezuela
and Brazil. Pan American began operations in mid-February 1999 and runs between
the U.S. Virgin Islands, Aruba, Venezuela, Colombia, Panama, Ecuador, Peru and
Chile. Arcos I, an 8,000 km cable system under construction with a planned
fourth quarter 2000 completion date, is expected to connect the United States
with numerous Caribbean and Latin American nations.


     Satellites. Our satellite transmissions use both C-band (4-7 GHz) and
Ku-band (10-18 GHz) frequencies. As of March 31, 2000, we had a total available
leased capacity of 327 MHz, 773 MHz of which we are using in the following
manner:



     - a total of 429 MHz of leased capacity on seven Intelsat satellites,
       various amounts of which are scheduled to expire between June 2000 and
       April 2008 (our satellite capacity on the Intelsat satellites is leased
       both directly by our operating subsidiaries and through subleases with
       Intelsat participants, such as Argentina's Comision Nacional de
       Comunicaciones)


     - satellite capacity on the New Sky Satellite 806 satellite for 39.9 MHz,
       which expires in 2009


     - 60 MHz of capacity on Brasilsat, which expires in 2002



     - 115 MHz of capacity on Nahuelsat's Nahuel-1 satellite, which expires
       between January 2002 and August 2003



     - 54 MHz of capacity on PanAmSat's PAS-1 satellite until the end of the
       useful life of the satellite (estimated to be December 31, 2001)



     - 70 MHz of capacity on PanAmSat's PAS-5 satellite, which expires between
       the end of 2003 and January 2009



     - 5 MHz of capacity on Mexico's Solidaridad-II satellite, which expires in
       December 2002



     Our lease payments for satellite capacity totaled approximately $34.6
million in 1999 and $8.7 million during the first three months of 2000.


     We will contract for additional leased satellite capacity as business
requires. A portion of our satellite capacity is leased by our wholly owned
subsidiary, International Satellite Capacity Holding, NG. This subsidiary's
principal function is to lease private satellite capacity from satellite
carriers and then sublease this capacity at market rates to our operating
subsidiaries. We believe that this method of centralizing our leasing of
satellite capacity provides us with better terms.

CUSTOMERS

     Overview. We have grown rapidly since the commencement of our operations in
1990. Our customer base has increased from 125 corporate customers in two
countries at December 31, 1992 to 1,745 corporate customers in seven countries
at December 31, 1999. Larger entities, which often have significant needs for
reliable, cost-effective data transmissions and other telecommunications
services, were the first to use our customized telecommunications services. As a
result, a significant portion of our revenues has been derived from our largest
customers. In addition, because of our relatively short operating history
outside of Argentina and Colombia, a significant number of our customers,
including our largest customers, are located in those two countries. As our
business matures and as we commence the operation of the Broadband Network, we
expect that the average size of our customers will decline.


     Our customers consist of major governmental agencies, financial
institutions and leading national and multinational corporations and private
sector companies, including YPF/Repsol, Royal Dutch Shell, Banco de Galicia y
Buenos Aires, Siemens and Reuters. Our ten largest customers accounted for
approximately 17.1% of our revenues in 1999 and approximately 17.3% in 1998.


     Our ten largest customers as of December 31, 1999 were:

     - the Government of the Province of Buenos Aires

     - Banco de la Nacion Argentina, or BNA, a state-owned bank and the largest
       bank in Argentina, with over 500 branches throughout Argentina

     - YPF/Repsol, an integrated oil company that is one of the largest
       companies in Argentina

     - Corporacion Nacional de Ahorro y Vivienda, or Conavi, one of Colombia's
       largest financial institutions

     - the Government of the Province of Mendoza

     - Banco Cafetero Bancafe, a large Colombian state-owned financial
       institution

     - Perez Companc S.A., an Argentine energy conglomerate

     - Banco de Galicia y Buenos Aires, a private bank with more than 180
       branches in Argentina

     - BanColombia S.A., a private bank headquartered in Bogota, Colombia and
       the largest commercial bank in Colombia

     - Banco Mercantil SAICA, one of Venezuela's largest commercial banks

     The following table shows our customer concentration by country as of the
dates indicated. Totals presented do not include customers from our Internet
service and fax, store and forward service.

     Customer Contracts. Our contracts with our customers typically range in
duration from six months to five years and contracts with our private
telecommunications network customers are generally for three years. Contracts
generally may be terminated by the customer without penalty. The private
telecommunications network customers generally pay a one-time installation fee
and a fixed, monthly fee. We believe that as we commercialize our Broadband
Network, we will develop a more flexible pricing structure, using both a usage-
based billing and fixed fee-based billing model.

     Except in Brazil, our contracts generally provide for payment in U.S.
dollars or for payment in local currency linked to the exchange rate at the time
of invoicing between the local currency and the U.S. dollar.

                                       56
<PAGE>   57

The revenues of our customers are generally denominated in local currencies.
Although our customers include some of the largest and most financially sound
companies and financial institutions in their markets, devaluation of such
currencies relative to the U.S. dollar could have a material adverse effect on
the ability of our customers to pay us for our services. A currency devaluation
could also result in our customers seeking to renegotiate their contracts with
us or, alternatively, defaulting on their contracts.

SALES, MARKETING AND CUSTOMER SERVICES

     We view our relationship with our customers as a long-term partnership in
which customer satisfaction is of paramount importance. For this reason, we
apply an integrated approach to our sales, marketing and customer service
functions. We provide customer service 24 hours a day, 365 days a year. We use
customer service teams to develop and maintain long-term, cooperative
relationships with our customers. These relationships provide us with an
in-depth understanding of our customers' evolving telecommunications service
requirements and levels of service satisfaction. As a result of this approach,
we achieve high levels of customer satisfaction while being able to identify new
revenue generating opportunities, customer telecommunications solution
enhancements and product or service improvements previously overlooked or not
adequately addressed by the client.

     Within each segment of our market, the respective service team is
responsible both for sales to new customers as well as for service to existing
customers. In addition, each customer is assigned an account manager, who has
overall responsibility for relations with that customer. An important function
of the account manager is to identify new or enhanced services for existing
customers. We will use this team-oriented approach to service our private
network, Internet and other customer groups.

     For our private network customers, we designate a customer service team to
oversee all phases of initial customer contact, service planning, installation
and ongoing service. After we establish initial contact with a potential
customer, the service team conducts a thorough evaluation of the customer's
telecommunications needs. Following the completion of this evaluation, we create
a plan for these customers which describes our proposed tailor-made solution
using the appropriate components of our private telecommunications network
services. When we provide services to governmental agency customers, we often
submit these proposals in response to public bid solicitations and related
governmental bidding procedures that govern the contracting of services by
governmental agencies.

     To market our new and enhanced services, we are developing several service
teams, each focusing on a particular type of services. For example, our
telephony services will be marketed to resellers by a team focused only on
telephony service.

     In addition to salaried sales and marketing personnel, we often use the
services of third-party sales representatives to assist in generating sales and
managing the contract process between ourselves and our potential customers. We
typically pay these third parties a commission and royalties equal to a
percentage of the revenues we collect from any contract with those customers
obtained as a result of the efforts of the third-party sales representative.

     We observe and measure the satisfaction of our customers through our
service teams' frequent customer interaction and, more formally, through a
comprehensive annual survey conducted by an outside consultant hired by us. We
use the results of these surveys to evaluate the performance of our service
teams, to formulate annual customer service plans and to implement improvements
to meet and exceed customer expectations.

COMPETITION

     We compete on the basis of our experience, network quality, customer
service, range of services offered and price. Our competitors fall into three
broad categories:

     - PTOs in each country where we operate

     - other companies that operate competing satellite and terrestrial data
       transmission businesses, including newer entrants from more developed
       telecommunications markets outside of Latin America

     - large international telecommunications carriers

                                       57
<PAGE>   58

     In the past, the PTOs and international telecommunications carriers have
focused on local and long-distance telephony services. In the future, however,
they may focus on the private telecommunications network systems segment of the
telecommunications market. These entities have significantly greater financial
and other resources than we do, including greater access to financing. These
competitors may also be able to subsidize their private telecommunications
network businesses with revenues from public telephony.

     With the first group of competitors, our further expansion into the
telecommunications services market along with continued deregulation of the
telecommunications industry in Latin America, will bring us into more direct
competition with the PTOs. A number of PTOs in the countries where we operate
have established and marketed "large customer" or "grand user" business teams in
an attempt to provide dedicated services to the type of customer that represents
our most important target market.


     We believe that by maintaining our position as a reliable, high quality
provider of telecommunications services while strengthening the quality of our
network and the breadth of service offerings through the Broadband Network, we
will be able to maintain our current customers and successfully attract new
customers. We might consider strategic alliances and other cooperative ventures
with the PTOs in the area of private telecommunications network services to take
advantage of each partner's relative strengths.


     In the second category, our competitors include international satellite
telecommunications providers and local data transmission providers. We believe
that we are able to compete successfully in data transmission services because
we offer a broad array of services and provide high quality, custom-designed
services that are tailored to meet the specific needs of each customer. Among
our competitors in this category are a number of new market entrants, including:

     - Diginet, a fixed wireless broadband services provider that is building a
       network in metropolitan Buenos Aires and has announced plans to enter the
       Brazilian telecommunications market

     - MetroRED Telecommunications, a data transmission service operator in
       Argentina that recently commenced offering local network services in the
       cities of Sao Paulo and Rio de Janeiro in Brazil

     - NetStream, an established fiber optic network service provider that AT&T
       recently acquired and that earlier this year began providing fiber optic
       cable local network services to businesses in Sao Paulo and Rio de
       Janeiro, Brazil and plans to build fiber optic networks in Belo
       Horizonte, Curitiba, Brasilia and Porto Alegre in 2000

     - Engeredes S.A., an infrastructure and data services provider that will
       use both fiber optic and wireless links to connect the cities of Belo
       Horizonte, Rio de Janeiro and Sao Paulo in Brazil

     - NetUno, a local exchange carrier and provider of broadband local access,
       Internet and private network services in Venezuela


     In the third category, major telecommunications carriers have indicated
their intention to enter the market as deregulation in Latin America and
elsewhere opens new market opportunities. For example, AT&T announced in
November 1999 that it planned to form a new company, AT&T Latin America, by
merging the operations of U.S. telecommunications company, FirstCom Corp. and
Brazil-based Netstream, which companies AT&T recently acquired, with Keytech LD,
a local exchange carrier that is licensed to offer wireless, high-speed internet
and other telecommunications services in Argentina. AT&T Latin America will have
assets in Argentina, Brazil, Chile, Colombia and Peru and is expected to expand
into Venezuela. We believe that increasing competition will significantly affect
our pricing policies. We cannot assure you that competition from these alliances
will not adversely affect our financial condition or results of operations. See
"Risk Factors -- We face significant competition in Latin America." The
competition we face in each of our countries of operation is described in the
"-- Description of Country Operations" section below.


     Furthermore, we cannot assure you that competing technologies will not
become available that will negatively affect our position, although we believe
that we have the flexibility to act quickly to take advantage of any significant
technological development. For example, new technologies such as DSL can
significantly enhance the speed of traditional copper lines. These technologies
could enable our PTO competitors to offer customers new high speed services
without undergoing the expense of replacing their existing twisted-pair copper
networks. This, in turn, could negate our last mile advantage. Our private
telecommunications services could also face future competition from entities
using or proposing to use new or emerging voice and data

                                       58
<PAGE>   59

transmission services or technologies which are not widely available in Latin
America, such as space based systems dedicated to data distribution services,
generally known as little-LEOs and broadband systems.

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

     The principal barriers to entry for prospective providers of private
telecommunications network services such as ours are the development of the
requisite understanding of customer needs and the technological and commercial
experience and know-how, infrastructure to provide quality services to meet
those needs and capital.

REGULATION

     Domestic Service. We are subject to regulation by the national
telecommunications authorities of the countries where we operate, and our
operations require us to procure permits and licenses from these authorities.
While we believe that we have received all required authorizations from
regulatory authorities for us to offer our services in the countries in which we
operate, the conditions governing our service offerings may be altered by future
legislation or regulation which could affect our business and operations. The
regulatory regime in each of our countries of operation and our licenses and
permits are separately described in the country-specific business descriptions
under "-- Description of Country Operations" below.


     Cross-Border Service. We provide integrated data, voice and video
transmission services under the Interplus name between and among nineteen Latin
American and Caribbean countries and the United States. We currently are
prohibited by law from providing switched voice services to or from Argentina,
but we have received authorization to provide these services starting in
November 2000. International private line services such as Interplus are
traditionally provided by local carriers in each country acting as
correspondents and establishing dedicated telecommunications links between their
facilities. Due to our pan-Latin American presence, we are often able to offer
our Interplus service using our own facilities and personnel at both ends of the
private line circuit. As a result of this end-to-end control, we maintain
customer service and quality assurance at both ends of an Interplus link and
realize better margins than when we use a correspondent carrier.


     In countries where we do not maintain customer premises equipment or where
we are not authorized to operate in that fashion, our Interplus service uses our
facilities in the originating country to connect with a correspondent local
carrier in the destination country or vice-versa. To date, we have signed
Interplus correspondent agreements with carriers in seven Latin American and
Caribbean countries. We charge customers a monthly fee for Interplus which is
based on the capacity of the circuit provided.

     Deregulation. Various countries in Latin America have taken initial steps
towards deregulation in the telecommunications market during the last few years.
Several Latin American countries have completely or partially privatized their
national carriers, including Argentina, Brazil, Mexico and Venezuela.
Furthermore, some countries have scheduled the demonopolization of their
dominant telecommunications providers. For example, Argentina and Venezuela have
announced the demonopolization of public telephone services by their PTOs in
2000. We believe that this trend toward deregulation, while likely to increase
competition, will also present significant opportunities for us to expand our
private telecommunications network services to, from and within the region, as
well as to present opportunities for us in areas of telecommunications currently
permitted to be conducted only by the PTOs.

EMPLOYEES


     As of March 31, 2000, we employed a total of 1,153 persons, of whom 339
were employed by IMPSAT Argentina and 223 were employed by IMPSAT Colombia. The
number of our employees has generally increased and is expected to continue to
increase as a result of our expansion in the countries in which we


                                       59
<PAGE>   60

operate, including as a result of our development of the Broadband Network. We
do not have any long-term employment contracts with any of our employees,
including management, and none of our employees are members of any union. We
believe that our relations with our employees are good.

LEGAL MATTERS

     We are involved in or subject to various litigation and legal proceedings
incidental to the normal conduct of our business, including with respect to
regulatory matters.


     Prior to 1998, our fourth largest customer in Argentina was ENCOTESA, the
Argentine official postal service. In September 1997, the official postal
service in Argentina was privatized and its operations were succeeded to by
Correo Argentino S.A., the entity formed by a private consortium to acquire and
operate the Argentine postal system. In accordance with the privatization
structure, neither IMPSAT Argentina's accounts receivable nor the contract with
ENCOTESA were assumed by Correo Argentino, and the obligations under IMPSAT
Argentina's contracts with ENCOTESA were retained by the Argentine Government.
In November 1996, IMPSAT Argentina filed suit against ENCOTESA for amounts due
under IMPSAT Argentina's contracts with ENCOTESA totaling $5.6 million, plus
interest from the date of invoice. On December 27, 1996, ENCOTESA filed its
reply to IMPSAT Argentina's claim. The court has not yet ruled upon IMPSAT
Argentina's claim against ENCOTESA. IMPSAT Argentina has held and continues to
hold discussions and negotiations with the Argentine Government regarding the
settlement and payment of the amounts claimed against ENCOTESA. At September 30,
1999, we estimated that the net realizable value of the ENCOTESA receivables to
be zero and recorded an adjustment of $5.1 million on amounts due from ENCOTESA,
see "Risk Factors -- Our earnings will deteriorate if we cannot collect on our
customer accounts," and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."



     Prior to February 2000, IMPSAT Argentina had a past due account receivable
relating to IBM de Argentina totaling $2.2 million. IMPSAT Argentina had
recorded an allowance for 100% of this amount. The past due receivable was
recorded for services provided under a subcontract between IMPSAT Argentina and
IBM de Argentina relating to BNA. BNA, a state-owned bank and the largest bank
in Argentina, is and has been one of our ten largest customers. IBM de Argentina
filed suit against BNA for amounts due and owing under its direct contract with
BNA. IMPSAT Argentina has a direct contract with BNA to provide private network
telecommunications services on which BNA is generally current. On December 14,
1998, IMPSAT Argentina filed suit against IBM de Argentina for amounts due and
arising under IMPSAT Argentina's contract with IBM de Argentina totaling $2.2
million, plus interest from the date of invoice. On February 8, 2000, we signed
an agreement with IBM de Argentina to settle our lawsuit against them. Pursuant
to our settlement, IBM de Argentina paid approximately $2.0 million,
representing a recovery of 89.7% of the approximately $2.3 million amount
reserved.

DESCRIPTION OF COUNTRY OPERATIONS

     The following are brief descriptions of certain specific matters relating
to the operations of our subsidiaries in Argentina, Venezuela, Colombia,
Ecuador, the United States, Brazil and Mexico.

     IMPSAT ARGENTINA

     IMPSAT Argentina, our first subsidiary, was established in 1988 and began
commercial operations in 1990. We own a 100% equity interest in IMPSAT
Argentina.

     In Argentina, we provide our portfolio of services through our fiber optic,
wireless and satellite facilities. Our principal transmission facilities in
Argentina include our teleport in Buenos Aires, regional teleports located in
Cordoba, Mendoza, Rosario, Mar del Plata, Tucuman, La Plata and Neuquen, and
Teledatos networks in Buenos Aires, Cordoba, Mendoza, Rosario, Mar del Plata,
Tucuman and La Plata. Our Teledatos network in Buenos Aires includes
approximately 72 route kilometers of fiber.


     In addition, IMPSAT Argentina operates a microwave link that provides
telecommunications services between Buenos Aires and Mendoza. At March 31, 2000,
we had installed approximately 2,648 VSAT microstations and 497 Dataplus earth
stations in Argentina. We operate on both the C-band and Ku-band in Argentina
with access to the Intelsat 706, 709 and 805, PAS-1, PAS-3, PAS-5 and Nahuel-1
satellites. IMPSAT Argentina uses 15 GHz, 18 GHz and 23 GHz frequencies for
point-to-point data and value-added services. In addition, the Comision Nacional
de Comunicaciones recently granted IMPSAT Argentina a license for the use of the
38 GHz frequency nationwide for point-to-point and point-to-multipoint data and
value-added services.



     At March 31, 2000, IMPSAT Argentina had 778 customers. Financial
institution customers provided approximately 28% of IMPSAT Argentina's revenues
during 1999. The second largest sector of IMPSAT Argentina's customer base
consists of industrial and manufacturing companies, which represented
approximately 26% of its revenues during 1999. IMPSAT Argentina's largest
customers during 1999 included:



     - Gobierno de la Provincia de Buenos Aires (5.8% of IMPSAT Argentina's 1999
       revenues)


     - BNA (5.4% of IMPSAT Argentina's 1999 revenues)


     - YPF/Repsol (4.3% of IMPSAT Argentina's 1998 revenues)


     - Gobierno de Mendoza (3.2% of IMPSAT Argentina's 1999 revenues)

     Revenues from IMPSAT Argentina's top ten customers accounted for
approximately 30.6% of IMPSAT Argentina's revenues for 1999.

     IMPSAT Argentina is a leader in data transmission services in Argentina and
estimates that in 1999 it had over a 30% market share based on revenues. Our
principal competitors in Argentina include Telecom Soluciones and Advance
Telecomunicaciones.

     In May 1999, IMPSAT Argentina entered into a distribution agreement and a
supply agreement with Concert Communications Sales Limited, a global alliance
among British Telecommunications, AT&T and others, to provide network facilities
in Argentina on a non-exclusive basis. In addition, IMPSAT Argentina provides
co-location services to Concert in Argentina.

     The Argentine telecommunications sector is under the supervision and
control of the Comision Nacional de Comunicaciones and the Secretaria de
Comunicaciones. Prior to 1989, telecommunication services in Argentina were
provided by Empresa Nacional de Telecomunicaciones, the former state-owned
national telecommunications monopoly. In 1989, the Argentine government enacted
a series of laws to deregulate the telecommunications sector. Under the current
regime, domestic fixed switched basic telephone services are supplied
exclusively by Telefonica and Telecom Argentina. In March 1998, the Argentine
Government announced the demonopolization of telephony services of Telecom
Argentina and Telefonica and the deregulation of local and long-distance
telephony markets commenced in November 1999. International voice services are
supplied by Telecom International, a subsidiary of Telecom Argentina, and
Telefonica Larga Distancia, a subsidiary of Telefonica. Other services, such as
those rendered by IMPSAT Argentina, are provided on a nonexclusive basis upon
authorization by the Argentine Comision Nacional de Comunicaciones.

     IMPSAT Argentina has a license with no expiration date to provide data
transmission services with ancillary voice channels within Argentina. IMPSAT
Argentina's license is subject to no material conditions. Under the terms of the
license, IMPSAT Argentina may provide point-to-point voice service in Argentina
only if this voice transmission is accomplished without use of the local public
telephone networks and only in connection with providing a service channel to
its data transmission customers. In July 1999, IMPSAT Argentina received two
licenses from the Comision Nacional de Comunicaciones, one to operate local
telephony and the second to operate national and international long distance
telecommunications, both starting in November 2000.

     IMPSAT Argentina provides value-added services in the domestic and
international market pursuant to a license granted by the Secretaria de
Comunicaciones in September 1995. Value-added services include electronic data,
voice and fax mail, fax store and forward and Internet access. IMPSAT Argentina
has also obtained licenses with no expiration date to provide trunking and
paging services within Argentina, although it has no intention of entering into
this business. IMPSAT Argentina also has licenses with no expiration date to
provide domestic and international video conferencing services.

     Although some services are provided on a competitive basis, the Comision
Nacional de Comunicaciones is in charge of the authorization, supervision and
control of the telecommunications services. IMPSAT Argentina is required to pay
the Comision Nacional de Comunicaciones a monthly fee equal to 0.5% of its net
telecommunications revenues.

     IMPSAT COLOMBIA

     IMPSAT Colombia began operations in December 1992. We hold a 100% equity
interest in IMPSAT Colombia. In January 2000, we exchanged 4,624,714 shares of
our common stock for a 24.6% minority interest in IMPSAT Colombia owned by
member companies of the Sindicato Antioqueno. Sindicato Antioqueno, formed in
Medellin, Colombia in the mid-1970s, is a group of over 100 financial services,
food, textile and apparel, construction and real estate companies related
through cross-ownerships and interlocking directorates. Member companies of the
Sindicato Antioqueno include BanColombia, the largest commercial bank in
Colombia; Cementos Argos, Colombia's largest cement manufacturer; and Nacional
de Chocolates, one of Colombia's largest food processing firms. We refer to
Suramericana de Seguros, Suramericana de Capitalizacion and all other entities
affiliated with the Sindicato Antioqueno as the Suramericana Group.


     We provide our portfolio of services in Colombia through fiber optic,
wireless and satellite networks. Our principal transmission facilities in
Colombia include the teleport and Teledatos network in Bogota and regional
teleports and Teledatos networks located in Medellin, Cali and Barranquilla. Our
Teledatos network in Bogota is provided through a joint venture with ETB, the
Colombian PTO that provides local telephone service in the Bogota region. Under
the terms of the joint venture, ETB provides the fiber optic infrastructure for
the network while IMPSAT Colombia provides multiplexing equipment and terminal
equipment on customer premises, controls and monitors the network, provides
technical support and sells network services to customers. We also own and
operate a 698 route kilometer long-haul fiber optic network in Colombia
connecting Bogota, Cali, and Medellin, and we are constructing an additional
1,351 route kilometers to close the ring between Cali and Bogota and to extend
this network to reach Barranquilla. IMPSAT Colombia currently uses the 23 GHz
frequency for point-to-point data and voice services. In addition, in August
1998, we received an authorization from the Ministry of Communications to use
various frequencies within the 38 GHz frequency for the provision of
point-to-point and point-to-multipoint value-added services for a term of ten
years. At March 31, 2000, IMPSAT Colombia had approximately 741 VSAT
microstations and 295 Dataplus earth stations installed. IMPSAT Colombia
operates on the C-band and Ku-Band with access to PAS-1 and the Intelsat 601,
709 and 801 satellites.



     At March 31, 2000, IMPSAT Colombia had 585 customers. Financial
institutions provided approximately 51.5% of IMPSAT Colombia's revenues for
1999. The second largest sector of IMPSAT Colombia's customer base is composed
of manufacturing companies (including oil companies) which provided
approximately 23.5% of IMPSAT Colombia's revenues for 1999. IMPSAT Colombia's
largest customers during 1999 included:


     - BanColombia

     - SECAB, the administrator of government funds for Colombia's National
       Learning Service

                                       62
<PAGE>   63

     - Concasa, a savings and loan corporation

     - Conavi, one of Colombia's largest financial institutions and a member of
       the Suramericana Group

     - Banco de la Republica, the central bank of Colombia


     - Banco Cafetero Bancafe, a large financial institution


     Revenues from IMPSAT Colombia's top ten customers accounted for
approximately 28.5% of IMPSAT Colombia's revenues for 1999.

     In March 1999, we signed an eight-year agreement with the Ardila Lulle
Organization, the fourth largest conglomerate in Colombia. Ardila Lulle's
businesses are in industries such as bottling, textiles and media. We will
initially provide services to 52 of their subsidiaries and affiliates, although
the contract may be expanded to as many as 100 subsidiaries and affiliates. The
contract is valued at $32.9 million. The revenues for 1999 from this contract
totalled approximately $0.5 million.


     At March 31, 2000, we believe that we were a leader in terms of market
share in Colombia in VSAT and data transmission services. Our principal
competitors in Colombia are:


     - Telecom Colombia, a state owned PTO

     - Colomsat, S.A., a privately owned provider of facsimile, data and voice
       transmission services


     - Americatel Colombia, a company owned by Grupo Santo Domingo, Colombia's
       largest conglomerate, which provides voice, data and video services
       primarily to Grupo Santo Domingo


     - EMTELCO, a provider of data transmission and imaging services, which is
       owned by Empresas Publicas de Medellin, the largest telecommunications
       company in the province of Medellin


     - Telefonica Data Colombia, an affiliate of Spain's Telefonica S.A. that
       offers data, internet, videoconferencing, and other corporate network
       services in the main cities in Colombia


     - Comsatcol, a subsidiary of COMSAT Corporation

     The telecommunications industry in Colombia is subject to regulation by the
Colombian Ministry of Communications. Since 1991, the Ministry of Communications
has pursued a policy of liberalization, and has encouraged joint ventures
between public and private telecommunications companies to provide new and
improved telecommunications services.

     Due in part to this policy of liberalization, IMPSAT Colombia has obtained
the following licenses and authorizations:

     - in September 1991, a license to operate national and international
       digital information transmission services for a term of twenty years

     - in November 1997, an authorization to use satellite capacity on Intelsat
       satellites

     - in August 1998, a license that permits it to operate as a national
       telecommunications carrier for a term of ten years

     The licenses and authorizations may be renewed so long as IMPSAT Colombia
complies with the terms and conditions of the licenses and authorizations and
any applicable laws and regulations. The licenses and authorizations permit
IMPSAT Colombia to engage in digital voice, data and video transmission
services, the provision of value added services such as fax store and forward
and electronic mail and Internet access services, and authorizes use by IMPSAT
Colombia of radio frequencies and satellite links in Colombia necessary to
provide such services. IMPSAT Colombia is prohibited by the terms of the
licenses and authorizations from connecting to the Colombian public
telecommunications network for purposes of reselling voice communications.

     IMPSAT Colombia is required to pay taxes in an amount equal to 3% of its
gross revenues, less payments to terrestrial telecommunications providers, to
the Ministry of Communications.

     IMPSAT VENEZUELA

     IMPSAT Venezuela began operations in January 1993. We hold a 100% equity
interest in IMPSAT Venezuela.


     In Venezuela, we provide our portfolio of services through wireless,
satellite networks as well as leased fiber optic links. Our principal
transmission facility in Venezuela is our teleport in Caracas. We also have a
Teledatos network in Caracas. IMPSAT Venezuela uses the 10 GHz, 13 GHz and 23
GHz frequencies for point-to-point data and value-added services. In addition,
the Comision Nacional de Telecomunicaciones (CONATEL) granted IMPSAT Venezuela a
license to use the 10 GHz frequency for point-to-multipoint data and value-added
services. At March 31, 2000 we had 699 VSAT microstations and 90 Dataplus earth
stations in Venezuela. We operate on the C-band in Venezuela using the PAS-1,
PAS-5, New Skies 806 and the Intelsat 805 satellites. In addition, we operate on
the Ku-band using the Intelsat 805 satellite.



     At March 31, 2000, IMPSAT Venezuela had 198 customers. IMPSAT Venezuela's
largest customers are generally large national and multinational corporations.
IMPSAT Venezuela's largest customers during 1999 included:



     - Banco Mercantil SAICA


     - Reacciun, a national academic telecommunications network

     - Cadenas de Tiendas Venezolanas, S.A., one of Venezuela's largest retail
       department stores and supermarket chains

     - Corporacion Andina de Fomento, a multilateral development bank

     - Nabisco de Venezuela C.A., a subsidiary of multinational food and tobacco
       conglomerate RJR Nabisco Holdings Corp.

     - Instituto Nacional de Hipodromos, a horse racing track

     - Compania Occidental de Hidrocarburos, Inc., a subsidiary of Occidental
       Petroleum Corp.

     Revenues from IMPSAT Venezuela's top ten customers accounted for
approximately 27.5% of IMPSAT Venezuela's revenues for 1999.


     Banco Mercantil, which has more than 300 agencies throughout the country
and 15 agencies abroad, is one of the largest banks in Venezuela. Banco
Mercantil became IMPSAT Venezuela's customer in 1994 when it contracted for
three Interplus links. Since then, Banco Mercantil has steadily expanded the
quantity and range of private telecommunications network services it contracts
from us. In May 1999, after a competitive bidding process, IMPSAT Venezuela was
selected to provide the outsourcing of almost all of the private
telecommunications network needs of Banco Mercantil. Participants in this
bidding process included CANTV and Bantel, two of IMPSAT Venezuela's principal
competitors. We completed our implementation of the Banco Mercantil network
during the second quarter of 2000. The monthly revenue of this new contract is
approximately $340,000.



     IMPSAT Venezuela estimates that it had approximately 25.5% market share in
data transmission services based on revenues during 1999. Our principal
competitors in Venezuela include Compania Anonima Nacional de Telefonos de
Venezuela (CANTV), the Venezuelan PTO which is operated by a consortium led by
GTE Corporation; WorldCom, which provides, data transmission and value-added
services; T-Data, the data transmission and Internet services division of
Telcel, one of Venezuela's two cellular telephone providers; and Bantel, which
provides data and voice transmission services.


     The Venezuelan telecommunications industry is regulated by CONATEL, which
is under the jurisdiction of the Ministry of Infrastructure.

     In December 1992, IMPSAT Venezuela obtained a license to build, maintain
and operate a private telecommunications network for the transmission of data,
voice and video information. The license is valid for a period of ten years,
with an option to renew for an additional ten years. The license prohibits
IMPSAT Venezuela from providing voice services through the public switched
telephone networks operated by CANTV

                                       64
<PAGE>   65

and from interconnecting and sharing infrastructure with other operators of
private telecommunications networks for the transmission of voice services.

     In February 1996, IMPSAT Venezuela obtained a ten-year license, with an
option to renew for an additional ten years, to provide value-added services
such as fax store and forward, electronic mail and Internet access. This license
does not prohibit IMPSAT Venezuela from interconnecting with CANTV or other
private networks.

     In February 1996, IMPSAT Venezuela obtained a ten-year license which
permits it to interconnect with CANTV for the national and international
transmission of data. The license does not permit us to interconnect with CANTV
in connection with the transmission of voice.

     Under each of the licenses described above, IMPSAT Venezuela is or will be
required to pay taxes and fees in an amount equal to 5.5% of a stipulated
portion of its gross revenues from the services that are provided pursuant to
the license. In 1999, this stipulated portion of its gross revenues represented
approximately 44.9% of IMPSAT Venezuela's revenues.

     IMPSAT ECUADOR

     In January 1995, we began operations in Ecuador through our wholly owned
subsidiary IMPSAT Ecuador.

     In Ecuador, we provide our portfolio of services through fiber optic,
wireless and satellite links. IMPSAT Ecuador uses the 15 GHz and 23 GHz
frequencies for point-to-point data and value-added services. We operate on the
C-band in Ecuador with access to the PAS-1, PAS-5 and Intelsat 805 satellites.
Our main teleport is located in Quito, Ecuador and we have a regional teleport
in Guayaquil.


     At December 31, 1999, IMPSAT Ecuador's largest customers included Banco del
Pichincha, one of the largest Ecuadoran banks; Aduanas, the Ecuadoran customs
agency; Diners Club del Ecuador, a leading credit card company and Banco la
Previsora, another of Ecuador's largest banks. In addition, we provide
international telecommunications services for the regional PTO located in the
city of Cuenca. Revenues from IMPSAT Ecuador's top ten customers accounted for
approximately 28% of its revenues for 1999.


     We believe that we are a leading provider of data transmission services in
Ecuador with a 49% market share based on revenues for 1999. Our principal
competitors in Ecuador include:

     - Andinatel and Pacifictel, Ecuadoran state-owned PTOs

     - Suratel, S.A., which provides national and international SCPC and voice
       services

     - Consorcio Ecuatoriano de Telecomunicaciones S.A., which provides national
       and international SCPC services and cellular telephony

     - Ram Telecom Telecomunicaciones S.A., which provides national SCPC
       services

     The telecommunications industry in Ecuador is regulated by the Consejo
Nacional de Telecomunicaciones and the Secretaria Nacional de Telecomunicaciones
and is under the control and supervision of the Superintendencia de
Telecomunicaciones.

     In June 1994, IMPSAT Ecuador obtained a 15-year license to provide data,
voice and video transmission services so long as it does not use the installed
networks owned by the Ecuadoran PTOs or any other company granted a monopoly for
the provision of fixed telephony services. The license authorizes the
installation, operation and exploitation by IMPSAT Ecuador of a satellite system
to offer national and international information transmission services, including
the construction of two teleports (in Quito and Guayaquil), VSAT microstations
and Dataplus earth stations. IMPSAT Ecuador is required to pay an annual fee
equal to 6% of certain of its revenues, which historically has represented
approximately half of IMPSAT Ecuador's revenues.

     In March 1998, Secretaria Nacional de Telecomunicaciones granted IMPSAT
Ecuador a ten-year renewable license to provide value-added services. Included
in the value-added services that IMPSAT Ecuador may offer are Internet services.

     IMPSAT USA

     Our wholly owned subsidiary, IMPSAT USA, began offering international
private telecommunications services between Latin America and North America in
February 1996.

     IMPSAT USA operates owned teleports throughout Florida and has leased
teleport facilities in New Jersey.


     IMPSAT USA targets corporate, ISP and telecommunications carrier customers.
IMPSAT USA's corporate sales efforts focus on providing multinational
corporations with extensive voice and data telecommunications needs, which are
the primary end-users in the U.S./Latin American market for international
private-line services. IMPSAT USA offers Internet services to Latin American
ISPs and provides telecommunications services to international long-distance
carriers. As of March 31, 2000, IMPSAT USA was providing services to 50
customers (excluding intercompany accounts).



     IMPSAT USA has an agreement to provide private network communications
services to Citicorp Global Technology, Inc. at 23 locations throughout Latin
America. In addition, IMPSAT USA provides Crowley American Transport, a
California-based logistics and maritime transport provider, with international
links for voice, video and data services at 47 sites in Central and South
America. IMPSAT USA also provides UBESA, the Ecuadoran subsidiary of Dole Fresh
Fruit International Ltd., with international data links between Florida and 5
locations in South America and ABN AMRO Bank with links covering nine locations
throughout Central and South America.


     IMPSAT USA's Internet services customers include Sony Music, Millicom,
Telcel (Paraguay), Celcaribe (Colombia) and Telemovil. IMPSAT USA also provides
Internet access services to Latin American ISPs such as CMET (Chile), Metrocall
(Panama), T-Net (Venezuela), Netsys (Honduras) and Inter Red (Colombia).


     As part of its telecommunications offerings, IMPSAT USA provides MCI Global
Resources, Inc. with circuits from Florida to WorldCom customer locations in
Honduras and Colombia.



     IMPSAT USA expects intense competition in the market for international
private telecommunications services between the United States and Latin America.
This competition is expected to come primarily from large long-distance carriers
(AT&T, WorldCom and Sprint) and Latin American PTOs, as well as from alternative
regional carriers. We believe IMPSAT USA can compete effectively by offering
better end-to-end customer service and quality assurance in Latin America
through its regional knowledge and in-country contacts using IMPSAT sister
companies.


     As a provider of telecommunications between the United States and foreign
countries, IMPSAT USA is subject to the jurisdiction of the Federal
Communications Commission. The FCC has authorized IMPSAT USA to provide
facilities-based and resold international telecommunications services.
Currently, IMPSAT USA provides private telecommunications services which, among
other things, means that IMPSAT USA is exempt from most FCC regulation.

     Although IMPSAT USA currently does not operate as a common carrier, it is
still subject to FCC regulations governing universal service. The FCC's
universal service rules generally require a provider of interstate
telecommunications to contribute a certain percentage, historically
approximately 5%, of its interstate and international end user revenue to the
universal service programs. Historically, IMPSAT USA has not contributed to the
universal service program because it did not provide any interstate
telecommunications. IMPSAT USA may be required to contribute to the universal
service program in the future, under current FCC rules, if IMPSAT USA's end user
revenues for interstate services exceed 8% of its end user revenues from
interstate and international services.

     The FCC is responsible for licensing all radio communications, including
satellite-based radio transmissions, to, from and within the United States.
IMPSAT USA holds non-common carrier earth station licenses and is therefore
subject to FCC regulations governing their operation. Recently, the FCC has
granted earth station operators, such as IMPSAT USA, the right to obtain direct
access to the Intelsat satellite system, a multilateral treaty-based system,
instead of having to obtain access through COMSAT, the U.S. signatory to

                                       66
<PAGE>   67

the Intelsat treaty. IMPSAT USA has requested the right to obtain direct access
to Intelsat, which should make it less expensive for IMPSAT USA to access
Intelsat services.

     IMPSAT BRAZIL

     IMPSAT Brazil was established to apply for a value-added telecommunications
license in Brazil and to develop this business in Brazil. We have a 99.9%
ownership interest in IMPSAT Brazil. IMPSAT Brazil is headquartered in Sao Paulo
and has offices in Rio de Janeiro, Curitiba, Belo Horizonte and Brasilia.

     We provide our portfolio of services using leased satellite capacity. Last
mile solutions in metropolitan areas are anticipated initially to be delivered
through wireless and fiber optic links leased from local PTOs. IMPSAT Brazil
operates its network through two teleports located in Sao Paulo and Curitiba. A
teleport is currently under development in Rio de Janeiro, and we may construct
additional teleports in other Brazilian cities. Our operations in Brazil use the
C-bands and Ku-bands on Brazilsat, PanAmSat, Intelsat and Nahuel satellites.


     At March 31, 2000, IMPSAT Brazil had a total of 103 customers, including
Shell do Brasil S.A., Ericsson, YPF/Repsol, Mercedes Benz do Brasil, TV
Paranaense and Confederacao Nacional de Industrias.



     Brazil is by far the largest telecommunications market in Latin America and
has attracted and is expected to continue to attract numerous providers, many of
whom may be larger and better financed than we are. The presence of large
carriers in Brazil may negatively affect our prospects there. In July 1998, the
Brazilian government split Telebras, the former Brazilian national
telecommunications company, into 17 companies by region and type of provider.
These companies were subsequently privatized. Winning bidders for these
operating companies included Telecom Italia, WorldCom, Telefonica and Sprint. In
addition, numerous additional concessions to provide telephony and data
transmission services were granted. Winning bidders and concessionaires are also
likely to focus on parts of the Brazilian market beyond those in which they
initially obtain a concession.


     As the Brazilian telecommunications sector is further liberalized and
deregulated, competition is likely to come from current telecommunications
service providers in that country, including:


     - Embratel, Brazil's former state-owned, monopoly long-distance carrier in
       which WorldCom acquired a 52% interest in July 1998 as part of the
       Telebras privatization


     - COMSAT do Brazil Ltda.

     - MetroRED Telecomunicacoes S.A., a data services company that provides
       local network services in Sao Paulo and Rio de Janeiro and plans to build
       local networks in other cities as well. In addition, it plans to build a
       fiber optic long distance network among Sao Paulo, Rio de Janeiro and
       Belo Horizonte

     - NetStream, a fiber optic network service provider that AT&T recently
       acquired and that earlier this year launched fiber optic cable local
       network services for businesses in Sao Paulo and Rio de Janeiro, Brazil
       and plans to build fiber optic networks in Belo Horizonte, Curitiba,
       Brasilia and Porto Alegre in 2000

     - Engeredes S.A., an infrastructure and data transmission provider that
       will use both fiber optic and wireless links to connect the cities of
       Belo Horizonte, Rio de Janeiro and Sao Paulo in Brazil

     - Telefonica, the regional fixed switch telephony operator for the state of
       Sao Paulo


     - Intelig Telefonica SA, a joint venture of France Telecom, Sprint and
       National Grid, which holds a license to provide domestic and
       international long-distance telephony and data services. Brazil's
       telecommunications regulators have ordered Sprint to leave the joint
       venture in connection with Sprint's pending merger with WorldCom.



     - Global One, an affiliate of France Telecom that provides international
       telecommunications services, focusing on multinational companies


     In March 1999, IMPSAT Brazil entered into a distribution agreement and a
supply agreement with Concert Communications Sales Limited to provide network
facilities on a non-exclusive basis in Brazil. In addition, IMPSAT Brazil
provides co-location services to Concert in Brazil.

                                       67

     The telecommunications and postal services in Brazil are regulated by the
Ministry of Communications pursuant to the Telecommunications Law of 1962, as
amended. Brazil's telecommunications laws were significantly revised in
September 1997 when the Brazilian legislature enacted the General
Telecommunications Law. This law authorized the creation of the Agencia Nacional
de Telecomunicacoes (ANATEL), an independent agency that regulates all aspects
of telecommunications services, except radio and TV broadcasting, including the
granting of licenses under the General Telecommunications Law.

     Under the General Telecommunications Law, telecommunications services may
not be provided in Brazil without prior governmental authorization. In January
1998, ANATEL granted IMPSAT Brazil a ten-year license to sell corporate
telecommunications services (data, voice and video) using terrestrial and
satellite links to third parties and to provide circuits for use by other
telecommunication carriers. Additionally, in March 1999 IMPSAT Brazil was
authorized by ANATEL to lease satellite capacity directly from satellite
carriers.

     IMPSAT MEXICO

     IMPSAT Mexico was incorporated in 1994. We hold a 99.9% equity interest in
IMPSAT Mexico. We provide our portfolio of services in Mexico through a teleport
located in Mexico City. We operate on the C-band in Mexico with access to
Intelsat 709 and 805, which has been approved by the Secretaria de
Comunicaciones y Transportes (SCT), and to Solidaridad-II, a Mexican satellite.


     As of March 31, 2000, IMPSAT Mexico had 35 customers including:


     - Bimbo, a food industry company

     - Becton Dickinson, a medical equipment company

     - Laboratorios Syntex/Roche, a pharmaceutical company

     - SmithKline Beecham, a pharmaceutical company

     - ATSI de Mexico S.A. de C.V., a private pay phone operator and a
       subsidiary of American TeleSource International, Inc.

     - Andersen Consulting, one of the largest multinational consulting
       companies

     We believe IMPSAT Mexico's market share will continue to be minimal as it
is not presently a strategic focus of the company.

     Our principal competitors in Mexico include:

     - Telmex, which besides offering local and long distance telephony,
       provides data and video services through its wholly owned subsidiary, Red
       Uno

     - Alestra S.A., a joint venture of AT&T, Grupo Financiero Bancomer S.A.,
       and Grupo Industrial Alfa S.A., provides long-distance telecommunications
       and data transmission services using the AT&T brand


     - Avantel, which is owned by WorldCom and Banamex Accival, provides
       national and international data, voice and long distance telephony and
       Internet services


     Other competitors in Mexico include Global One, COMSAT, Optel
Telecommunications, Red Sat and Intervan.

     The Mexican telecommunications industry is regulated primarily by the SCT.
An agency of the SCT, Telecomunicaciones de Mexico, or Telecomm, is charged with
the regulation of non-national satellite and telegraph services. Telecomm
supervises carriers and allocates electronic frequencies for satellite
telecommunications.

     IMPSAT Mexico has a permit from the SCT for the installation, operation and
exploitation of a network of earth stations to provide dedicated-link services,
including VSAT services, for the transmission of voice, data and
videoconferencing signals. This permit provides that these services must use
Mexican satellites or those designated or approved by the Mexican government.
IMPSAT Mexico's permit does not restrict its ability to carry voice.
Interconnection of IMPSAT Mexico's network to networks in other countries
requires the approval of the SCT. While IMPSAT Mexico's permit is valid for 15
years from when it was obtained in May 1994, its terms and conditions may be
revised for a nominal fee after the first five years if the SCT believes changes
to be in the public interest. IMPSAT Mexico has the right to renew the permit
for an

                                       68
<PAGE>   69

additional 15 years if it has complied with the provisions of the permit and
agrees to accept any new conditions that may be imposed by the SCT.

     IMPSAT Mexico is required to pay 5% of its telecommunications services
income to the Mexican government along with certain fees for having its signals
transmitted and received by satellite, and nominal fees for the installation of
new earth stations.


     Mexican law restricts foreign investment in concession holders to no more
than a 49% interest. We have been advised by local Mexican counsel that this
restriction does not apply to IMPSAT Mexico because IMPSAT Mexico provides its
services pursuant to a permit, and does not hold a concession. In addition, the
law does not apply to concessions like ours that were granted prior to the law's
enactment.

STOCK OPTION GRANTS

     The following table shows information regarding grants of options to
purchase our common stock made by us during 1999 to each of the executive
officers named in the summary compensation table above. We granted no stock
appreciation rights during 1999. No stock options were exercised by the
executive officers named in the summary compensation table above during 1999.

     We computed potential realizable values by first multiplying the number of
shares of common stock subject to a given option by the option exercise price to
determine the initial aggregate stock value. We then assumed that the initial
aggregate stock value compounds at an annual 5% or 10% rate shown in the table
for the entire ten-year term of the option to determine the final aggregate
stock value. Finally, we subtracted from the final aggregate stock value the
initial aggregate stock value to determine the potential realizable value. The
5% and 10% assumed annual rates of stock appreciation are mandated by the rules
of the SEC and do not reflect our estimate or projection of future stock price
growth. Actual gains, if any, on stock option exercises depend upon the actual
future price of common stock and the continued employment of the option holders

                                       74
<PAGE>   75

throughout the vesting period. Accordingly, the potential realizable values
listed in this table may not be achieved.

AGGREGATE OPTION EXERCISES DURING 1999 AND OPTION VALUES ON DECEMBER 31, 1999


     No options were exercised during 1999. We have not included information on
the value of unexercised options held by the executive officers named in the
summary compensation table above as of December 31, 1999, because there was no
public market for our common stock in 1999.


STOCK OPTION PLANS


     1998 Stock Option Plan.  On December 21, 1998, IMPSAT's board of directors
and stockholders adopted the 1998 stock option plan, which provides for the
grant to our officers, key employees, consultants, advisors, directors or
affiliates of "incentive stock options" within the meaning of Section 422 of the
U.S. Internal Revenue Code of 1986, as amended, stock options that are
non-qualified for U.S. federal income tax purposes and stock appreciation
rights. A copy of the 1998 stock option plan is included as Exhibit 10.1 to our
1998 Annual Report on Form 10-K filed with the SEC. The total number of shares
of our common stock for which options may be granted pursuant to the 1998 stock
option plan is 4,776,016, subject to certain adjustments reflecting changes in
our capitalization. The 1998 stock option plan is currently administered by our
compensation committee. The compensation committee determines, among other
things, which of our officers, employees, consultants, advisors, affiliates and
directors will receive options under the plan, the time when options will be
granted, and the type of option (incentive stock options or non-qualified stock
options, or both) to be granted. Options granted under the 1998 stock option
plan are on such terms, including the number of shares subject to each option,
the time or times when the options will become exercisable, and the option price
and duration of the options, as determined by the compensation committee.


     The exercise price of incentive and non-qualified stock options is
determined by the compensation committee, but may not be less than the fair
market value of the common stock on the date of grant and the term of any such
option may not exceed ten years from the date of grant.

     Payment of the option price must be made by cash or, in the sole discretion
of the compensation committee, by promissory note, tender of shares of the
common stock then owned by the optionee or, subject to certain conditions, the
surrender to us of an exercisable option to purchase shares of common stock
under the 1998 stock option plan. Payment of the option price may also be made
by delivery to us, on a form prescribed by the compensation committee, of a
properly executed exercise notice and irrevocable instructions to a registered
securities broker approved by the compensation committee to sell the shares of
common stock held by the optionee and promptly deliver cash to us. Options
granted pursuant to the 1998 stock option plan are not transferable, except by
will or the laws of descent and distribution in the event of death. During an
optionee's lifetime, the option is exercisable only by the optionee or, in case
of disability, by the optionee's legal representative.

     Pursuant to the terms of our stock options, if a change in control of our
company occurs, all outstanding stock options become vested and fully
exercisable.

                                       75
<PAGE>   76

     Our board of directors has the right at any time and from time to time to
amend or modify the stock option plan, without the consent of our stockholders
(unless otherwise required by law) or optionees; provided, that no such action
may adversely affect options previously granted without the optionee's consent.
The expiration date of the 1998 stock option plan, after which no option may be
granted thereunder, is October 1, 2008.

     1999 Stock Option Plan.  On January 5, 2000, IMPSAT's board of directors
adopted the 1999 stock option plan, which provides for the grants to our key
officers and employees of stock options that are non-qualified for U.S. federal
income tax purposes. A copy of the 1999 stock option plan is filed as an exhibit
to the registration statement relating to the initial public offering of our
common stock. The terms of the 1999 stock option plan are otherwise identical to
those of the 1998 stock option plan except that:

     - The total number of shares of our common stock for which options may be
       and were granted pursuant to the stock option plan is 355,214

     - The exercise price is $1.69 per share of common stock

     - Ten percent, twenty percent, thirty percent and forty percent of the
       options granted vest on the fourth, fifth, sixth and seventh
       anniversaries, respectively, of the date of grant or upon a change of
       control of our company

     - The expiration date of the 1999 stock option plan is January 5, 2010

See "-- British Telecommunications."

BRITISH TELECOMMUNICATIONS

     On March 11, 1999, a share purchase agreement and related agreements were
entered into among IMPSAT, Nevasa Holdings and Nunsgate Limited, a wholly owned
subsidiary of British Telecommunications. Pursuant to the share purchase

to Nunsgate Limited for $125 million, and Nevasa Holdings agreed to sell
2,386,867 shares of our common stock to Nunsgate Limited for $25 million. These
transactions were consummated on April 19, 1999. On February 4, 2000, Nunsgate
Limited purchased from us an additional 2,850,000 shares of our common stock in
a private placement to maintain its approximate ownership share in us after our
initial public offering.

     We are a party to a shareholders agreement with Nevasa Holdings and
Nunsgate Limited dated as of March 10, 1999, a copy of which has been filed as
an exhibit to the registration statement relating to the initial public offering
of our common stock. Pursuant to the terms of this shareholders agreement, as
long as Nunsgate Limited owns 15% of our outstanding common stock (as determined
on a fully-diluted basis) and subject to certain conditions, Nunsgate Limited
has the right to nominate two members of our board of directors. Nevasa Holdings
has agreed to vote for the two Nunsgate Limited nominees to our board of
directors so long as Nunsgate Limited owns 15% of our outstanding common stock.

     As long as Nunsgate Limited owns 10% of our outstanding common stock (as
determined on a fully-diluted basis) and subject to certain conditions, Nunsgate
Limited has the right to:

     - consult with management on matters relating to us

     - inspect our books and records

                        DESCRIPTION OF OUR INDEBTEDNESS

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

     Senior Notes.  In July 1996, we completed the offering of our $125 million
principal amount of 12 1/8% Senior Notes due 2003, of which an aggregate of $125
million in principal amount is outstanding as of the date hereof. The 12 1/8%
notes bear interest at the rate of 12 1/8% per annum payable semiannually in
cash on January 15 and July 15 of each year. The 12 1/8% notes have the benefit
of a guarantee issued on a senior unsecured basis by IMPSAT Argentina.

     In June 1998, we completed our offering of our $225 million principal
amount of 12 3/8% Senior Notes due 2008, of which an aggregate of $225 million
in principal amount is outstanding as of the date of this prospectus. The
12 3/8% notes bear interest at the rate of 12 3/8% per annum payable
semiannually in cash on June 15 and December 15 of each year.

     The indentures under which our notes were issued contain a number of
covenants which, among other things:

     - restrict our ability to consolidate, merge or sell all or substantially
       all of our assets

     - create restrictions on the ability of our restricted subsidiaries to make
       certain payments, issue or sell stock of certain subsidiaries, and enter
       into transactions with stockholders or affiliates

     These indentures also restrict our and our restricted subsidiaries' ability
to:

     - incur additional indebtedness

     - create liens

     - engage in sale-leaseback transactions

     - make restricted payments

     - sell assets


     Vendor Financing.  On October 25, 1999, each of IMPSAT Argentina and IMPSAT
Brazil signed definitive agreements with Nortel to borrow up to approximately
$149.1 million and $148.3 million, respectively, of long-term vendor financing.
This vendor financing, which will be disbursed over a two year period with final
maturity in 2006, will be used by us to finance Nortel's construction of the
segments of the Broadband Network in each of Argentina and Brazil. At May 31,
2000 we had borrowed a total $104.7 million from Nortel and have unused
commitments of $192.7 million under these agreements.


     Subject to mandatory or optional prepayment under the terms of the vendor
financing, principal amounts borrowed by us will be repayable over the last five
years of a seven-year period beginning on October 25, 2001, and will bear
interest at LIBOR (or, under certain circumstances, prime rate) plus an
applicable margin, commencing on the first disbursement date. The vendor
financing is not revolving. Any amounts that are repaid or prepaid by us may not
be reborrowed.

     To secure repayment of disbursements under the vendor financing, we have
granted Nortel a first priority security interest over equipment, infrastructure
and other assets related to the Broadband Network and to be acquired by us with
the proceeds of the vendor financing. In addition, we have agreed to guarantee
the obligations of each of IMPSAT Argentina and IMPSAT Brazil under the vendor
financing agreements.

     If we sell or otherwise dispose of or suffer material losses with respect
to the property comprising Nortel's security under the financing and fail to
reinvest the proceeds within the time specified, then such proceeds must be used
to prepay the loans under the vendor financing. We are also mandated to prepay
amounts

                                       81
<PAGE>   82

borrowed under the vendor financing if we make voluntary or mandatory
prepayments under the indentures under which our notes are issued. In addition,
under certain circumstances, we are obligated to apply the proceeds of certain
sales of debt securities towards prepayments of the vendor financing. We are
permitted to make voluntary prepayments of amounts borrowed under the vendor
financing.

     The making of each disbursement under the vendor financing will be subject
to our satisfaction of several ongoing conditions. The vendor financing
agreements also contain a number of covenants that, among other things, limit
our ability to:

     - incur additional indebtedness

     - create liens and other encumbrances

     - sell or otherwise dispose of assets

     - make acquisitions, investments, loans and advances

     - merge or consolidate with another entity

     - engage in any business other than the telecommunications business

     - make distributions to our stockholders

     - enter into transactions with affiliates

     In addition, the vendor financing will require ongoing compliance by IMPSAT
Argentina and IMPSAT Brazil with certain financial and operating covenants,
including, without limitation, the maintenance of specified ratios of debt to
total capitalization, total debt to EBITDA, EBITDA to interest expense and
capital expenditure limitations.

                               THE EXCHANGE OFFER


     On February 16, 2000 we sold $300 million in principal amount of the old
notes in a private placement through Morgan Stanley & Co. Incorporated, as the
initial purchaser, to a limited number of institutional investors. In connection
with the sale of the old notes, we entered into a registration rights agreement
with Morgan Stanley & Co. Incorporated, dated as of February 16, 2000. Under
that agreement, we must, among other things, use our best efforts to file with
the Commission a registration statement under the Securities Act of 1933
covering the exchange offer and to cause the registration statement to become
effective under the Securities Act of 1933. Upon the effectiveness of the
registration statement, we must also offer each holder of the old notes the
opportunity to exchange their old notes for an equal principal amount of new
notes. The new notes will be issued without a restrictive legend and may be
reoffered and resold by the holders of the new notes without restrictions or
limitations under the Securities Act of 1933. We are making the exchange offer
to comply with our obligations under the registration rights agreement. A copy
of the registration rights agreement has been filed as an exhibit to the
registration statement of which this prospectus is a part. You are a holder with
respect to the exchange offer if you are a person in whose name any old notes
are registered on our books or if you have obtained a properly completed
assignment of old notes from a registered holder.



     Upon the terms and subject to the conditions set forth in this prospectus
and in the letter of transmittal, we will accept any and all old notes validly
tendered and not withdrawn prior to 5:00 p.m., New York City time, on the day
the exchange offer expires. The expiration date is 5:00 p.m., New York City time
on July 21, 2000, unless we extend the exchange offer, in which case, the
expiration date will be the latest date and time to which the exchange offer is
extended.



     As of the date of this prospectus, $300 million in principal amount of the
notes are outstanding. This prospectus, together with the letter of transmittal,
is being sent to all registered holders of the old notes known to us on this
date. Our obligation to accept old notes for exchange pursuant to the exchange
offer is subject to certain customary conditions described below under
" -- Certain Conditions to Exchange Offer."


     We may, in our sole discretion, extend the expiration date of the exchange
offer, and thereby delay acceptance of any old notes for exchange, by giving
oral or written notice of such extension to the holders of the old notes. During
any such extension, all old notes previously tendered will remain subject to the
exchange offer and may be accepted for exchange by us. Any old notes not
accepted for exchange for any reason will be returned without expense to the
tendering holder of the old notes as promptly as practicable after the
expiration or termination of the exchange offer.

     Old notes you tender in the exchange offer must be in denominations of
principal amount of $1,000 or any integral multiple thereof.

     We expressly reserve the right to amend or terminate the exchange offer,
and not to accept for exchange any old notes not previously accepted for
exchange, upon the occurrence of any of the conditions of the exchange offer
specified below under "-- Certain Conditions to the Exchange Offer." We will
give oral or written notice of any extension, amendment, non-acceptance or
termination to the holders of the old notes as promptly as practicable. We will
give you notice of any extension of the expiration date by means of a press
release or other public announcement no later than 9:00 a.m., New York City
time, on the next business day after the previously scheduled expiration date.

PROCEDURES FOR TENDERING OLD NOTES

     Only a registered holder of old notes may tender such old notes in the
exchange offer. If you tender your old notes and do not withdraw them prior to
the expiration date of the exchange offer, you will be deemed to have an
agreement with us in accordance with the terms and subject to the conditions set
forth in this prospectus and in the letter of transmittal.

     To tender in the exchange offer, you must complete, sign and date an
original or facsimile letter of transmittal, have the signatures thereon
guaranteed if required by the letter of transmittal, and mail or

                                       85
<PAGE>   86

otherwise deliver the letter of transmittal to the exchange agent for receipt
before the expiration date of the exchange offer. In addition, either:

     - the exchange agent must receive from you certificates for the old notes,
       along with the letter of transmittal, on or before the expiration date or

     - the exchange agent must receive, prior to the expiration date of the
       exchange offer, a timely confirmation of transfer by book-entry of those
       old notes into the exchange agent's account at The Depository Trust
       Company, also known as DTC, as set forth in the procedure for book-entry
       transfer described below, or

     - you must comply with the guaranteed delivery procedures described below

     The method of delivery of old notes and the letter of transmittal and all
other required documents to the exchange agent is at your risk. Instead of
delivery by mail, it is recommended that you use an overnight or hand delivery
service, properly insured. In all cases, you should allow sufficient time to
assure delivery to the exchange agent before the expiration date of the exchange
offer. Do not send the letter of transmittal or old notes to us.

     If your old notes are registered in the name of a broker, dealer,
commercial bank, trust company, or other nominee and you wish to tender those
old notes, you should contact the registered holder promptly and instruct that
registered holder to tender the old notes on your behalf. If you wish to tender
your old notes on your own behalf, you must, prior to completing and executing
the letter of transmittal and delivering your old notes, either make appropriate
arrangements to register ownership of the old notes in your name or obtain a
properly completed assignment from the registered holder. The transfer of
registered ownership of old notes may take considerable time.

     Signatures on a letter of transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an eligible institution unless the old notes
tendered are:

     - by a registered holder of the old notes who has not completed the box
       entitled "Special Issuance Instructions" or "Special Delivery
       Instructions" on the letter of transmittal

     - for the account of an eligible institution

     In the event that signatures on a letter of transmittal or a notice of
withdrawal, as the case may be, are required to be guaranteed, such guarantee
must be made by an eligible financial institution. An eligible institution,
including most banks, savings and loan associations and brokerage houses, is a
financial institution that is a participant in the:

                - Securities Transfer Agents Medallion Program, or

                - New York Stock Exchange Medallion Program, or

                - Stock Exchanges Medallion Program

     If the letter of transmittal is signed by a person other than the
registered holder of any old notes, the old notes must be endorsed or
accompanied by a written instrument or instruments of transfer or exchange.

     The written instrument should be in satisfactory form as shall be
determined by us, in our sole discretion, and:

     - duly executed by the registered holder exactly as the name or names of
       the registered holder or holders appear on the old notes

     - with the signature thereon guaranteed by an eligible institution

     We will determine all questions as to the validity, form, eligibility,
including time of receipt, acceptance of tendered old notes, and withdrawal of
tendered old notes, in our sole discretion. All of our determinations will be
final and binding. We reserve the absolute right to reject any old notes not
properly tendered or any old notes the acceptance of which would, in the opinion
of our counsel, be unlawful. We also reserve the right to

                                       86
<PAGE>   87

waive any defects, irregularities or conditions of tender as to particular old
notes. Our interpretation of the terms and conditions of the exchange offer,
including the instructions in the letter of transmittal, will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of old notes must be cured within the time we determine.
Although we intend to notify holders of old notes of defects or irregularities
with respect to tenders of old notes, neither we, nor the exchange agent, or any
other person will incur any liability for failure to give this notification.

     If trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity sign the letter of transmittal or any of the old notes or bond power,
those persons should so indicate when signing, and evidence satisfactory to us
of their authority to so act must be submitted with the letter of transmittal,
unless we waive that requirement.

     Based on a previous interpretation by the staff of the SEC set forth in
no-action letters to third parties, we believe that the new notes issued
pursuant to the exchange offer in exchange for old notes may be offered for
resale, resold, and otherwise transferred by a holder thereof, other than:

     - a broker-dealer who purchases such new notes directly from us to resell
       pursuant to Rule 144A or any other available exemption under the
       Securities Act of 1933

     - a person that is our affiliate (within the meaning of Rule 405 under the
       Securities Act of 1933) without compliance with the registration and
       prospectus delivery provisions of the Securities Act of 1933, provided
       that the holder is acquiring the new notes in the ordinary course of its
       business and is not participating, and has no arrangement or
       understanding with any person to participate, in the distribution of the
       new notes

     By tendering, each holder will represent to us that, among other things,
the new notes acquired pursuant to the exchange offer are being obtained in the
ordinary course of its business, whether or not such person is the holder, and
that neither the holder nor such other person has any arrangement or
understanding with any person to participate in the distribution of the new
notes. You are our "affiliate", as defined under Rule 405 of the Securities Act
of 1933, if you are engaged in or intend to engage in, or have an arrangement or
understanding with any person to participate in, a distribution of the new
notes. If an affiliate, you or any such other person

     - may not rely on the applicable interpretation of the staff of the SEC

     - must comply with the registration and prospectus delivery requirements of
       the Securities Act of 1933 in connection with any resale transaction

     In addition, each broker-dealer that receives new notes for its own account
in exchange for old notes, where such old notes were acquired by the
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus meeting the
requirements of the Securities Act of 1933 in connection with any resale of the
new notes. See "Plan of Distribution." The letter of transmittal states that by
so acknowledging and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act of 1933.


     This prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with resales of new notes received
in exchange for old notes where such old notes were acquired by the
broker-dealer as a result of market-making activities or other trading
activities. We have agreed that, for a period of 180 days after the expiration
date, we will make this prospectus available to any broker-dealer for use in
connection with any such resale. See "Plan of Distribution."


     To comply with the securities laws of certain jurisdictions, if applicable,
the new notes may not be offered or sold unless they have been registered or
qualified for sale in such jurisdictions or any exemption from registration or
qualification is available and is complied with. We have agreed, pursuant to the
registration rights agreement, subject to certain limitations specified therein,
to register or qualify the new notes for offer or sale under the securities laws
of such jurisdictions as any holder reasonably requests in writing. Unless a
holder so requests, we do not currently intend to register or qualify the sale
of the new notes in any such jurisdictions.

                                       87
<PAGE>   88

ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES

     Upon satisfaction or waiver of all of the conditions to the exchange offer,
we will accept, promptly after the expiration date, all old notes properly
tendered and will issue the new notes promptly after acceptance of the old
notes. See "-- Certain Conditions to the Exchange Offer" below. For purposes of
the exchange offer, we will be deemed to have accepted properly tendered old
notes for exchange when, as and if we have given oral or written notice thereof
to the exchange agent.

     The holder of each old note accepted for exchange will receive as set forth
below under "Description of the Notes -- Book-Entry, Delivery and Form" a new
note having a principal amount equal to that of the surrendered old note.
Accordingly, registered holders of new notes on the relevant record date for the
first interest payment date following the consummation of the exchange offer
will receive interest accruing from the most recent date to which interest has
been paid on the old notes or, if no interest has been paid, from February 15,
2000. Old notes accepted for exchange will cease to accrue interest from and
after the date of consummation of the exchange offer. You will not receive any
payment in respect of accrued interest on your old notes that are accepted for
exchange on any interest payment date the record date for which occurs on or
after consummation of the exchange offer. If the exchange offer is not
consummated and a Shelf Registration Statement is not declared effective on or
prior to August 16, 2000, the annual interest rate borne by the notes will be
increased to 14.25%. Upon consummation of the exchange offer or the
effectiveness of the Shelf Registration Statement, the interest rate on the
notes will revert to 13.75%. See "Description of the Notes -- Registration
Rights." Old notes not tendered or not accepted for exchange will continue to
accrue interest from and after the date of consummation of the exchange offer.

     In all cases, issuance of new notes for old notes that are accepted for
exchange pursuant to the exchange offer will be made only after

     - timely receipt by the exchange agent of


        - certificates for such old notes or



        - a timely book-entry confirmation of such old notes into the exchange
          agent's account at the Depository Trust Company


     - a properly completed and duly executed letter of transmittal and all
       other required documents


     If any tendered old notes are not accepted for any reason set forth in the
terms and conditions of the exchange offer or if any of your old notes are
submitted for a greater principal amount than you desire to exchange, such
unaccepted or non-exchanged old notes will be returned to you without expense to
you (or, in the case of old notes tendered by book-entry transfer into the
exchange agent's account at DTC pursuant to the book-entry procedures described
below, such non-exchanged old notes will be credited to your account maintained
with DTC) as promptly as practicable after the expiration or termination of the
exchange offer.


BOOK-ENTRY TRANSFER

     The exchange agent will make a request to establish an account with respect
to the old notes at DTC for the purposes of the exchange offer within two
business days after the date of this prospectus, and any financial institution
that is a participant in DTC's systems may make book-entry delivery of old notes
by causing DTC to transfer the old notes into the exchange agent's account at
DTC in accordance with DTC's procedures for transfer. However, although delivery
of old notes may be effected through book-entry transfer at DTC, the letter of
transmittal or facsimile thereof, with any required signature guarantees and any
other required documents, must, in any case, be transmitted to and received by
the exchange agent at the address set forth below under "-- Exchange Agent" on
or prior to the expiration date of the exchange offer, unless the holder
complies with the guaranteed delivery procedures described below.

                                       88
<PAGE>   89

GUARANTEED DELIVERY PROCEDURES

     If you desire to tender old notes and (1) the old notes are not immediately
available, or (2) time will not permit your old notes or other required
documents to reach the exchange agent before the expiration date, or the
procedure for book-entry transfer cannot be completed on a timely basis, you may
effect a tender if

     - the tender is made through an eligible institution

     - on or prior to 5:00 P.M., New York City time, on the expiration date, the
       exchange agent receives from such eligible institution a properly
       completed and duly executed letter of transmittal (or a facsimile
       thereof) and notice of guaranteed delivery, substantially in the form
       provided by us (by telegram, telex, facsimile transmission, mail or hand
       delivery), setting forth your name and address as the holder of old notes
       and the amount of old notes tendered, stating that the tender is being
       made thereby and guaranteeing that within three New York Stock Exchange
       ("NYSE") trading days after the date of execution of the notice of
       guaranteed delivery, the certificates for all physically tendered old
       notes, in proper form for transfer, or a book-entry confirmation, as the
       case may be, and any other documents required by the letter of
       transmittal will be deposited by the eligible institution with the
       exchange agent, and

     - you will deposit the certificates for all physically tendered old notes,
       in proper form for transfer, or a book-entry confirmation, as the case
       may be, and any other documents required by the letter of transmittal
       with the eligible institution within three NYSE trading days after the
       date of execution of the notice of guaranteed delivery

WITHDRAWAL RIGHTS

     Except as otherwise provided, you may withdraw tender of old notes at any
time prior to 5:00 p.m., New York City time, on the expiration date of the
exchange offer.

     To withdraw a tender of old notes in the exchange offer, a written or
facsimile transmission notice of withdrawal must be received by the exchange
agent at its address set forth herein prior to 5:00 p.m., New York City time, on
the expiration date of the exchange offer. Any such notice of withdrawal must

     - specify the name of the person having deposited the old notes to be
       withdrawn

     - identify the old notes to be withdrawn

     - be signed by the holder in the same manner as the original signature on
       the Letter of Transmittal by which the old notes were tendered or be
       accompanied by documents of transfer sufficient to have the exchange
       agent register the transfer of the old notes in the name of the person
       withdrawing the tender and

     - specify the name in which any old notes are to be registered, if
       different from that of the person who deposited the old notes to be
       withdrawn

     We will determine all questions as to the validity, form, and eligibility
of the notices, which determination will be final and binding on all parties.
Any old notes so withdrawn will be deemed not to have been validly tendered for
purposes of the exchange offer, and no new notes will be issued with respect to
those old notes unless the old notes so withdrawn are validly retendered.

     Any old notes that have been tendered but that are withdrawn or not
accepted for payment will be returned to the holder of those old notes, or in
the case of old notes tendered by book-entry transfer, will be credited to an
account maintained with DTC, without cost to the holder as soon as practicable
after withdrawal, rejection of tender or termination of the exchange offer.
Properly withdrawn old notes may be retendered by following one of the
procedures described above under "-- Procedures for Tendering" at any time
before the expiration date of the exchange offer.

CERTAIN CONDITIONS TO THE EXCHANGE OFFER

     Notwithstanding any other provisions of the exchange offer, and subject to
our obligations pursuant to the registration rights agreement, we shall not be
required to accept for exchange, or to issue new notes in exchange for, any old
notes and may terminate or amend the exchange offer, if at any time before the
acceptance of such new notes for exchange, any of the following events shall
occur:

     - any injunction, order or decree shall have been issued by any court or
       any governmental agency that would prohibit, prevent or otherwise
       materially impair our ability to proceed with the exchange offer

     - the exchange offer will violate any applicable law or any applicable
       interpretation of the staff of the SEC

     The foregoing conditions are for our sole benefit and may be asserted by us
in whole or in part at any time and from time to time in its sole discretion.
Our failure at any time to exercise any of the foregoing rights shall not be
deemed a waiver of any such right and such right shall be deemed an ongoing
right which may be asserted at any time and from time to time.

     In addition, we will not accept for exchange any old notes tendered, and no
new notes will be issued in exchange for any such old notes, if at such time any
stop order is threatened by the SEC or in effect with respect to the
registration statement of which this prospectus is a part or the qualification
of the Indenture under the Trust Indenture Act of 1939, as amended.

     The exchange offer is not conditioned on any minimum principal amount of
old notes being tendered for exchange.

FEES AND EXPENSES

     We will not make any payment to brokers, dealers, or others soliciting
acceptances of the exchange offer.

     We will pay the cash expenses to be incurred in connection with the
exchange offer. Such expenses include registration fees, fees and expenses of
the exchange agent and trustee, accounting and legal fees and printing costs,
among others.

TRANSFER TAXES

     Holders who tender their old notes for exchanges will not be obligated to
pay any transfer taxes in connection therewith, except that holders who instruct
us to register new notes in the name of, or request that old notes not tendered
or not accepted in the exchange offer be returned to, a person other than the
registered tendering holder will be responsible for the payment of the
applicable transfer tax thereon.

CONSEQUENCES OF FAILURE TO EXCHANGE OLD NOTES

     If you do not exchange your old notes for new notes pursuant to the
exchange offer, you will continue to be subject to the provisions in the
indenture regarding transfer and exchange of the old notes and the restrictions
on transfer of such old notes as set forth in the legend thereon as a
consequence of the issuance of the old notes pursuant to exemptions from, or in
transactions not subject to, the registration requirements of the Securities Act
of 1933 and applicable state securities laws.


     In general, the old notes may not be offered or sold, unless registered
under the Securities Act of 1933 and applicable state securities laws. We do not
currently anticipate that we will register old notes under the Securities Act of
1933. See "Description of the Notes -- Registration Rights." Based on
interpretations by the staff of the SEC, as set forth in no-action letters
issued to third parties, we believe that new notes issued pursuant to the
exchange offer in exchange for old notes may be offered for resale, resold or
otherwise transferred by holders thereof (other than any such holder which is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act of 1933) without compliance with the registration and prospectus delivery
provisions of the Securities Act of 1933, provided that such new notes are
acquired in the ordinary course or such holders' business and such holders,
other than broker-dealers, have no arrangement or understanding with any person
to participate in the distribution of such new notes. However, the SEC has not
considered the exchange offer in the context of a no-action letter and we can
give you no assurance that the staff of the SEC would make a similar
determination with respect to the exchange offer as in such other circumstances.

                            DESCRIPTION OF THE NOTES


     The notes were issued under an Indenture, dated as of February 16, 2000
(the "Indenture"), between us, as issuer, and The Bank of New York, as Trustee,
Registrar and Paying Agent (the "Trustee"), and Banque Internationale a
Luxembourg S.A., as Paying Agent and Transfer Agent. The following summary of
certain provisions of the Indenture is not complete and is subject to, and is
qualified by reference to, all the provisions of the Indenture. A copy of the
Indenture is available from us upon request. Whenever particular defined terms
of the Indenture are referred to but not defined, those terms are incorporated
herein by reference. For definitions of capitalized terms used in the following
summary, see "-- Certain Definitions." As used in this "Description of the
Notes," the term "company" means IMPSAT Fiber Networks, Inc., and excludes any
subsidiaries.


     The following description of the terms of the Indenture is a summary. This
summary does not restate the Indenture and excludes certain definitions and
complex legal terminology contained in the Indenture. While we believe this
summary contains all of the information about the Indenture that is important to
your decision to exchange the old notes for new notes, it does not include all
of the provisions of the Indenture that you may feel are important. It is the
Indenture, and not this summary, that defines your rights as a noteholder. If
you would like to read the Indenture in its entirety, you may obtain a copy from
us by contacting us as the address set forth on page 3 of this prospectus.

GENERAL


     The notes will be unsecured unsubordinated obligations of our company,
limited to $300 million aggregate principal amount, and will mature on February
15, 2005 at their principal amount. Each note bears interest at the rate per
annum shown on the front cover of this prospectus from and including the Closing
Date, to but excluding August 15, 2000 (and each successive period thereafter
from and including an interest payment date, to but excluding the next interest
date or at maturity, as the case may be), or from and including the most recent
interest payment date to which interest has been paid or provided for, payable
semiannually (to holders of record at the close of business on the February 1 or
August 1 immediately preceding the interest payment date) on February 15 and
August 15 of each year, commencing August 15, 2000, to but excluding February
15, 2001 (and each successive period thereafter from and including an interest
payment date, to but excluding the next interest payment date or at maturity, as
the case may be). Interest will be computed on the basis of a 360-day year of
twelve 30-day months. If a payment date is a date other than a business day at a
place of payment, payment may be made at that place on the next succeeding day
that is a business day and no interest shall accrue for the intervening period.



     Principal of and interest on the notes will be payable, and the notes may
be exchanged or transferred, at the office or agency of our company in the
Borough of Manhattan, the City of New York (which initially will be the
corporate trust office of the Trustee at 101 Barclay Street, Floor 21 West, New
York, New York 10286) and at the offices of the Luxembourg Paying and Transfer
Agent in Luxembourg upon presentation and/or surrender of the notes; provided
that, at our option, payment of interest may be made by check mailed to the
holders at their addresses as they appear in the Security Register at the close
of business on the February 1 and August 1 immediately preceding the relevant
interest payment date. Principal of the notes will be paid in U.S. dollars at
their maturity, provided that we will not make payment to the holder unless the
note is surrendered to a Paying Agent. For so long as the notes are listed on
the Luxembourg Stock Exchange and the rules of such stock exchange so require,
we will maintain a Paying Agent and a Transfer Agent in Luxembourg where notes
may be presented for registration of transfer or for exchange and where notes
may be presented for payment. We have initially appointed Banque Internationale
a Luxembourg as such paying agent and transfer agent in Luxembourg.



     The notes will be issued only in fully registered form, without coupons, in
denominations of $1,000 of principal amount and any integral multiple thereof.
See "-- Book-Entry; Delivery and Form." Notes will be initially represented by
one or more permanent global notes. Any holder of or beneficial owner of an
interest in


                                       92
<PAGE>   93


a global note shall, by acceptance of such global note, be deemed to have agreed
that transfers of beneficial interests in such global note may be effected only
through the a book-entry system maintained by the Depositary (or its agent), and
that ownership of a beneficial interest in the note shall be required to be
reflected in a book-entry. See "-- Book Entry; Delivery and Form." No service
charge will be made for any registration of transfer or exchange of notes, but
we may require payment of a sum sufficient to cover any transfer tax or other
similar governmental charge payable in connection therewith. We will not make
any additional payments to holders in respect of any withholding or deduction
for, or on account of, any present or future taxes, duties, assessments or
government charges of whatever nature imposed or levied by or on behalf of any
governmental authority in relation to any payment by us of interest on, or
principal of, the notes.


     Subject to the covenants described below under "Covenants" and applicable
law, we may issue additional notes under the Indenture. The notes offered hereby
and any additional notes subsequently issued would be treated as a single class
for all purposes under the Indenture.

     For purposes of determining compliance with the Indenture, the U.S. dollar
equivalent of any amounts denominated in a foreign currency shall be calculated
using the noon dollar buying rate in New York City for wire transfers of such
currency as published by the Federal Reserve Bank of New York on the date such
foreign currency amount is received, incurred or paid. For other financial
reporting purposes, currency translations will be performed in accordance with
U.S. generally accepted accounting practices.

OPTIONAL REDEMPTION

     The notes may be redeemed, in whole or in part, at any time at our option
at a redemption price (the "Make-Whole Price") equal to the greater of (1) 100%
of the principal amount thereof or (2) as determined by an Independent
Investment Banker, the sum of the present values of the Remaining Scheduled
Payments discounted to the redemption date on a semiannual basis (assuming a
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate,
plus, in each case, accrued and unpaid interest (including Additional Interest,
as provided for in the Registration Rights Agreement), if any, to the date of
redemption.

     "Adjusted Treasury Rate" means with respect to any redemption date, the
rate per annum equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date, plus 0.50%.

     "Comparable Treasury Issue" means the United States Treasury Security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the notes that would be utilized, at the time of selection
and in accordance with customary financial practice, in pricing new issues of
corporate debt securities of comparable maturity to the remaining term of the
notes.

     "Comparable Treasury Price" means, with respect to any redemption date, (1)
the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
business day preceding such redemption date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities" or (2) if such release (or any successor release) is not
published or does not contain such prices on such business day, (A) the
Reference Treasury Dealer Quotations for such redemption date, after excluding
the highest and lowest of such Reference Treasury Dealer Quotations, or (B) if
the Trustee obtains fewer than three such Reference Treasury Dealer Quotations,
the average of all such Quotations.

     "Independent Investment Banker" means any Reference Treasury Dealer
appointed by the Trustee after consultation with us.

     "Reference Treasury Dealer" means each of Morgan Stanley & Co.
Incorporated, Chase Securities Inc., First Union Capital Markets, a division of
Wheat First Securities, Inc., NationsBanc Montgomery Securities LLC and TD
Securities (USA) Inc. and their respective successors; provided, however, that
if any of the

                                       93
<PAGE>   94

foregoing shall cease to be a primary U.S. Government securities dealer in New
York City (a "Primary Treasury Dealer"), our company shall substitute another
Primary Treasury Dealer.

     "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average as determined by
the Trustee, of the bid and asked prices of the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third business day preceding such redemption date.

     "Remaining Scheduled Payments" means, with respect to each note to be
redeemed, the remaining scheduled payments of the principal thereof and interest
thereon that would be due after the related redemption date but for such
redemption; provided, however, that, if such redemption date is not an interest
payment date with respect to such note, the amount of the next succeeding
scheduled interest payment thereon will be reduced by the amount of interest
accrued and unpaid thereon to such redemption date.

     In addition, at any time before February 16, 2003, we may redeem up to 35%
of the principal amount of the notes originally issued with the Net Cash
Proceeds of one or more public or private issuances of Capital Stock (other than
Disqualified Stock) at any time or from time to time in part, at a redemption
price of 113.750% of the principal amount thereof on the redemption date,
together with accrued and unpaid interest, if any, thereon; provided that (i) at
least 65% of the principal amount of the notes remain outstanding after each
such redemption and (ii) notice of such redemption is mailed within 60 days of
such issuance.


     In the case of any partial redemption, selection of the notes for
redemption will be made by the Trustee in compliance with the requirements of
the principal national securities exchange, if any, on which the notes are
listed or, if the notes are not listed on a national securities exchange, by lot
or by such other method as the Trustee in its sole discretion shall deem to be
fair and appropriate. If any note (of greater than $1,000 in principal amount at
maturity) is to be redeemed in part only, the notice of redemption relating to
such note shall state the portion of the principal amount thereof to be
redeemed. A new note in principal amount equal to the unredeemed portion thereof
will be issued in the name of the holder thereof upon cancellation of the
original note.


     Unless we default in payment of the redemption price, on and after the
redemption date, interest will cease to accrue on the notes or portion thereof
called for redemption.

SINKING FUND

     There will be no sinking fund payments for the notes.

REGISTRATION RIGHTS


     We have agreed to use our best efforts to prepare, file and cause to become
effective a registration statement with respect to a registered offer (the
"Exchange Offer") to exchange the notes for an issue of unsubordinated notes of
our company, which we call the exchange notes, with terms identical to the
notes, except that the exchange notes will not bear legends restricting their
transfer. We plan to list the new notes on the Luxembourg Stock Exchange.



     We have agreed to use our best efforts to have the exchange offer
consummated before August 16, 2000. The registration statement for the notes
will remain effective until we are able to close the exchange offer.


     If the Securities and Exchange Commission, also known as the SEC or the
Commission, does not permit us to effect the exchange offer, or under certain
other circumstances, we will use our best efforts to cause to become effective a
shelf registration statement with respect to resales of the old notes. Under
such circumstances, the shelf registration statement will remain effective until
the expiration of the time period referred to in Rule 144(k) under the
Securities Act, or such shorter period that will terminate when all notes
covered by the shelf registration statement have been sold pursuant to the shelf
registration statement.


     If the Exchange Offer for the notes is not consummated or a shelf
registration statement is not declared effective on or prior to August 16, 2000,
interest on the notes will accrue at the rate of 14.25% per annum and

                                       94
<PAGE>   95


be payable in cash semiannually on each interest payment date, commencing
February 15, 2001, until the consummation of a registered exchange offer or the
effectiveness of a shelf registration statement.



     If we effect the Exchange Offer, we will be entitled to close the Exchange
Offer 20 business days after the commencement thereof, provided that we have
accepted all notes theretofore validly surrendered in accordance with the terms
of the Exchange Offer. Notes not tendered in the Exchange Offer shall bear
interest at the applicable rate set forth on the cover page of this Memorandum
and be subject to all of the terms and conditions specified in the Indenture and
to the transfer restrictions described in "Transfer Restrictions."



     The foregoing summary of the material provisions of the Registration Rights
Agreement is not complete. You should read the proposed form of the Registration
Rights Agreement. A copy of the proposed Registration Rights Agreement is
available from us.


RANKING


     The indebtedness evidenced by the notes ranks equally among themselves and
with all of our other unsecured unsubordinated indebtedness. At March 31, 2000,
we (on an unconsolidated basis but giving effect to guarantees of $6.7 million
of indebtedness of our subsidiaries) had approximately $356.7 million of
indebtedness (other than the notes). We are a holding company, and the notes are
effectively subordinated to all existing and future liabilities (including trade
payables) of our subsidiaries. At March 31, 2000, excluding intercompany
payables and the guarantee of our 12 1/8% Senior Guaranteed Notes due 2003 by
one of our subsidiaries, our subsidiaries had approximately $339.5 million of
liabilities, including approximately $170.2 million of indebtedness. The
Indenture will permit us and our subsidiaries to incur substantial amounts of
additional indebtedness.



CERTAIN DEFINITIONS



     Set forth below is a summary of certain of the defined terms used in the

          to be refinanced is subordinated in right of payment to the notes,
          such new Indebtedness, by its terms or by the terms of any agreement
          or instrument pursuant to which such new Indebtedness is issued or
          remains outstanding, is expressly made subordinate in right of payment

      (6) Guarantees of the notes and Guarantees of Indebtedness of our company
          by any Restricted Subsidiary provided the Guarantee of such

          covenant described below;

      (7) Indebtedness (including Guarantees) Incurred to finance the cost
          (including the cost of design, development, acquisition, construction,

          of Capitalized Lease and acquisitions of the Capital Stock of a Person
          that becomes a Restricted Subsidiary to the extent of the fair market
          value of the equipment, inventory or network assets so acquired) by

      (8) Indebtedness of our company not to exceed, at any one time
          outstanding, two times the sum of (A) the Net Cash Proceeds received

          the issuance and sale of its Capital Stock (other than Disqualified
          Stock) to a Person that is not a Subsidiary of our company, to the
          extent (I) such capital contribution or Net Cash Proceeds are not, at
          our company's option, added to the amount calculated pursuant to
          clause (C)(ii) of the first paragraph of the "Limitation on Restricted
          Payments" covenant or used to make a Restricted Payment pursuant to
          clause (3), (4) or (8) of the second paragraph of the "Limitation on
          Restricted Payments" covenant and (II) if such capital contribution or
          Net Cash Proceeds are used to consummate a transaction pursuant to
          which our company Incurs Acquired Indebtedness, the amount of such Net

          so Incurred and (B) 80% of the fair market value of property (other
          than cash and cash equivalents) received by our company after the
          Closing Date from the sale of its Capital Stock (other than

          or Capital Stock is used to consummate a transaction pursuant to which
          our company Incurs Acquired Indebtedness, 80% of the fair market value
          of the property received exceeds one-half of the amount of Acquired
          Indebtedness so Incurred; provided that such Indebtedness does not
          mature prior to the Stated Maturity of the notes and has an Average
          Life longer than the notes;

          aggregate principal amount equal to the aggregate principal amount of
          the Certificates of Deposit and shall not be

                                       109

          outstanding at any time that the Certificates of Deposit are not
          validly outstanding and beneficially owned by our company;

     (12) Indebtedness of any Restricted Subsidiary, to the extent that our
          company is the beneficial owner of such Indebtedness and such
          Indebtedness is evidenced by a promissory note or participation
          certificate issued to our company by the record holder of such
          Indebtedness;

     (13) Indebtedness of our company, the proceeds of which are used to make an
          Investment in Intelsat, in an amount at any one time outstanding not
          to exceed $30 million; provided that our company reasonably believes,
          at the time such Indebtedness is Incurred, that the benefits of such
          Investment will result in cash flow sufficient to cover the payment of
          interest and principal on such Indebtedness; and

     (14) subordinated Indebtedness of our company (in addition to Indebtedness
          permitted under clauses (1) through (13) above) in an aggregate
          principal amount outstanding at any time not to exceed $100 million,
          less any amount of such Indebtedness permanently repaid as provided
          under the "Limitation on Asset Sales" covenant described below.

     (b) Notwithstanding any other provision of this "Limitation on
Indebtedness" covenant, the maximum amount of Indebtedness that our company or a
Restricted Subsidiary may Incur pursuant to this "Limitation on Indebtedness"
covenant shall not be deemed to be exceeded, with respect to any outstanding
Indebtedness due solely to the result of fluctuations in the exchange rates of
currencies.

     (c) For purposes of determining any particular amount of Indebtedness under
this "Limitation on Indebtedness" covenant, (1) Guarantees, Liens or obligations
with respect to letters of credit supporting Indebtedness otherwise included in
the determination of such particular amount shall not be included and (2) any
Liens granted pursuant to the equal and ratable provisions referred to in the
"Limitation on Liens" covenant described below shall not be treated as
Indebtedness. For purposes of determining compliance with this "Limitation on
Indebtedness" covenant, in the event that an item of Indebtedness meets the
criteria of more than one of the types of Indebtedness described in the above
clauses, our company, in its sole discretion, shall classify, and from time to
time may reclassify, such item of Indebtedness and only be required to include
the amount and type of such Indebtedness in one of such clauses.

  Limitation on Restricted Payments

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly,

     (1) declare or pay any dividend or make any distribution on or with respect
         to its Capital Stock held by Persons other than our company or any
         Restricted Subsidiary (other than (x) dividends or distributions
         payable solely in shares of its or such Restricted Subsidiary's Capital
         Stock (other than Disqualified Stock) or in options, warrants or other

     (3) make any voluntary or optional principal payment, or voluntary or
         optional redemption, repurchase, defeasance, or other acquisition or

         subordinated in right of payment to the notes or


     (4) make any Investment, other than a Permitted Investment, in any Person
         (such payments or any other actions described in clauses (1) through
         (4) above being collectively "Restricted Payments")

     if, at the time of, and after giving effect to, the proposed Restricted
Payment:

     (A) a Default or Event of Default shall have occurred and be continuing,


     (B) our company could not Incur at least $1.00 of Indebtedness under the

<PAGE>   111


     (C) the aggregate amount of all Restricted Payments (the amount, if other
than in cash, to be determined in good faith by the Board of Directors, whose
determination shall be conclusive and evidenced by a Board Resolution) made
after the Closing Date shall exceed the sum of (i) 50% of the aggregate amount
of the Adjusted Consolidated Net Income (or, if the Adjusted Consolidated Net
Income is a loss, minus 100% of the amount of such loss) (determined by
excluding income resulting from transfers of assets by our company or a
Restricted Subsidiary to an Unrestricted Subsidiary) accrued on a cumulative
basis during the period (taken as one accounting period) beginning on the first
day of the fiscal quarter commencing July 1, 1998 and ending on the last day of
the last fiscal quarter preceding the Transaction Date for which reports have
been filed with the Commission or provided to the Trustee pursuant to the
"Commission Reports and Reports to Holders" covenant plus (ii) the aggregate Net
Cash Proceeds received by our company after June 17, 1998 as a capital
contribution or from the issuance and sale of its Capital Stock (other than
Disqualified Stock) to a Person who is not a Subsidiary of our company,
including an issuance or sale permitted by the Indenture of Indebtedness of our
company for cash subsequent to the Closing Date upon the conversion of such
Indebtedness into Capital Stock (other than Disqualified Stock) of our company,
or from the issuance to a Person who is not a Subsidiary of our company of any
options, warrants or other rights to acquire Capital Stock of our company (in
each case, exclusive of any convertible indebtedness, Disqualified Stock or any
options, warrants or other rights that are redeemable at the option of the
holder, or are required to be redeemed, prior to the Stated Maturity of the
notes), in each case except to the extent such Net Cash Proceeds are used to
Incur Indebtedness pursuant to clause (8) of the second paragraph under the
"Limitation on Indebtedness" covenant, plus (3) an amount equal to the net
reduction in Investments made pursuant to this first paragraph of this
"Limitation on Restricted Payments" covenant in any Person resulting from
payments of interest on Indebtedness, dividends, repayments of loans or
advances, or other transfers of assets, in each case to our company or any
Restricted Subsidiary or from the Net Cash Proceeds from the sale of any such
Investment (except, in each case, to the extent any such payment or proceeds are
included in the calculation of Adjusted Consolidated Net Income), or from
redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries (valued
in each case as provided in the definition of "Investments"), not to exceed, in
each case, the amount of Investments previously made by our company or any
Restricted Subsidiary in such Person or Unrestricted Subsidiary.


     The foregoing provision shall not be violated by reason of:

      (1) the payment of any dividend within 60 days after the date of
          declaration thereof if, at said date of declaration, such payment
          would comply with the foregoing paragraph;

      (2) the redemption, repurchase, defeasance or other acquisition or
          retirement for value of Indebtedness that is subordinated in right of
          payment to the notes including premium, if any, and accrued and unpaid
          interest, with the proceeds of, or in exchange for, Indebtedness
          Incurred under clause (3) of the second paragraph of part (a) of the
          "Limitation on Indebtedness" covenant;

      (3) the repurchase, redemption or other acquisition of Capital Stock of
          our company (or options, warrants or other rights to acquire such
          Capital Stock) in exchange for, or out of the proceeds of a capital
          contribution or a substantially concurrent offering of, shares of
          Capital Stock (other than Disqualified Stock) of our company (or
          options, warrants or other rights to acquire such Capital Stock);

      (4) the making of any principal payment or the repurchase, redemption,
          retirement, defeasance or other acquisition for value of Indebtedness
          of our company which is subordinated in right of payment to the notes
          in exchange for, or out of the proceeds of a capital contribution or a
          substantially concurrent offering of, shares of the Capital Stock
          (other than Disqualified Stock) of our company (or options, warrants
          or other rights to acquire such Capital Stock);

      (5) payments or distributions to dissenting stockholders pursuant to
          applicable law, pursuant to or in connection with a consolidation,
          merger or transfer of assets that complies with the provisions of the
          Indenture applicable to mergers, consolidations and transfers of all
          or substantially all of the property and assets of our company;

                                       111
<PAGE>   112

      (6) Investments in Unrestricted Subsidiaries not to exceed, at any one
          time outstanding, the greater of (A) $5 million or (B) 10% of
          Consolidated EBITDA for the preceding four quarters for which reports
          have been filed pursuant to the "Commission Reports and Reports to
          Holders" covenant;

      (7) Investments in any Person the primary business of which is related,
          ancillary or complementary to the business of our company and its
          Restricted Subsidiaries on the date of such Investments; provided that
          the aggregate amount of Investments made pursuant to this clause (7)
          does not exceed $20 million;

      (8) Investments acquired in exchange for Capital Stock (other than
          Disqualified Stock) of our company or with the proceeds of such
          Capital Stock; provided that such proceeds are so applied within 90
          days of receipt thereof;

      (9) the declaration or payment of dividends on our common stock following
          a public offering of common stock of up to 6% per annum of the Net
          Cash Proceeds received by our company in such Public Equity Offering;

     (10) other Restricted Payments in an aggregate amount not to exceed $25
          million; provided that, except in the case of clauses (1) and (3), no
          Default or Event of Default shall have occurred and be continuing or
          occur as a consequence of the actions or payments set forth therein.
          The value of any Restricted Payment made other than in cash shall be
          the fair market value thereof. The amount of any Investment
          "outstanding" at any time shall be deemed to be equal to the amount of
          such Investment on the date made, less the return of capital to our
          company and its Restricted Subsidiaries with respect to such
          Investment (up to the amount of such Investment).

     Each Restricted Payment permitted pursuant to the preceding paragraph
(other than the Restricted Payment referred to in clause (2) thereof, an
exchange of Capital Stock for Capital Stock or Indebtedness referred to in
clause (3) or (4) thereof and an Investment referred to in clause (6) thereof),
and the Net Cash Proceeds from any capital contribution or any issuance of
Capital Stock referred to in clauses (3), (4) and (8), shall be included in
calculating whether the conditions of clause (C) of the first paragraph of this
"Limitation on Restricted Payments" covenant have been met with respect to any
subsequent Restricted Payments. If the proceeds of an issuance of Capital Stock
of our company are used for the redemption, repurchase or other acquisition of
the notes, or Indebtedness that is pari passu with the notes, then the Net Cash
Proceeds of such issuance shall be included in clause (C) of the first paragraph
of this "Limitation on Restricted Payments" covenant only to the extent such
proceeds are not used for such redemption, repurchase or other acquisition of
Indebtedness. For purposes of determining compliance with this "Limitation on
Restricted Payments" covenant, in the event that a Restricted Payment meets the
criteria of more than one of the types of Restricted Payments described in
clauses (1) through (10) of the preceding paragraph, our company, in its sole
discretion, shall classify such Restricted Payment and only be required to
include the amount and type of such Restricted Payment in one of such clauses.

  Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries

     We will not, and will not permit any Restricted Subsidiary to, create or
otherwise cause or suffer to exist or become effective any consensual
encumbrance or restriction of any kind on the ability of any Restricted
Subsidiary to

     (1) pay dividends or make any other distributions permitted by applicable
         law on any Capital Stock of such Restricted Subsidiary owned by our
         company or any other Restricted Subsidiary,

     (2) pay any Indebtedness owed to our company or any other Restricted
         Subsidiary,


     (3) make loans or advances to our company or any other Restricted
         Subsidiary or


     (4) transfer any of its property or assets to our company or any other
         Restricted Subsidiary.

     The foregoing provisions shall not restrict any encumbrances or
restrictions:

                                       112
<PAGE>   113

     (1) existing on the Closing Date in the Indenture or any other agreements
         in effect on the Closing Date, and any extensions, refinancings,
         renewals or replacements of such agreements; provided that the
         encumbrances and restrictions in any such extensions, refinancings,
         renewals or replacements are no less favorable in any material respect
         to the holders than those encumbrances or restrictions that are then in
         effect and that are being extended, refinanced, renewed or replaced;

     (2) existing under or by reason of applicable law;

     (3) existing with respect to any Person or the property or assets of such
         Person acquired by our company or any Restricted Subsidiary, existing
         at the time of such acquisition and not incurred in contemplation
         thereof, which encumbrances or restrictions are not applicable to any
         Person or the property or assets of any Person other than such Person
         or the property or assets of such Person so acquired;

     (4) in the case of clause (4) of the first paragraph of this "Limitation on
         Dividend and Other Payment Restrictions Affecting Restricted
         Subsidiaries" covenant, (A) that restrict in a customary manner the
         subletting, assignment or transfer of any property or asset that is a
         lease, license, conveyance or contract or similar property or asset,
         (B) existing by virtue of any transfer of, agreement to transfer,
         option or right with respect to, or Lien on, any property or assets of
         our company or any Restricted Subsidiary not otherwise prohibited by
         the Indenture or (C) arising or agreed to in the ordinary course of
         business, not relating to any Indebtedness, and that do not,
         individually or in the aggregate, detract from the value of property or
         assets of our company or any Restricted Subsidiary in any manner
         material to our company or any Restricted Subsidiary;

     (5) with respect to a Restricted Subsidiary and imposed pursuant to an
         agreement that has been entered into for the sale or disposition of all
         or substantially all of the Capital Stock of, or property and assets
         of, such Restricted Subsidiary during the period between the execution
         of such agreement and the closing thereunder within three months of
         such execution;

     (6) with respect to Restricted Subsidiaries in which, on and subsequent to
         the Closing Date, our company and other Restricted Subsidiaries only
         make Investments that are evidenced by unsubordinated promissory notes
         that bear a reasonable rate of interest and are payable prior to the
         Stated Maturity of the notes; provided that such encumbrances and
         restrictions expressly allow the payment of interest and principal on
         such promissory notes;

     (7) encumbrances or restrictions solely of the type referred to in clause
         (3) or (4) of the preceding paragraph that are contained in any
         stockholders' agreement, joint venture agreement or similar agreement
         among owners of Common Stock of a Restricted Subsidiary; provided that
         such restrictions consist solely of requirements that transactions
         between such Restricted Subsidiaries and affiliates thereof (including
         our company and its Restricted Subsidiaries) be on fair and reasonable
         terms no less favorable to such Restricted Subsidiary than could be
         obtained in a comparable arm's-length transaction with a Person that is
         not such an affiliate; or

     (8) contained in the terms of any Indebtedness or any agreement pursuant to
         which such Indebtedness was issued if (A) the encumbrance or
         restriction applies only in the event of a payment default or a default
         with respect to a financial covenant contained in such Indebtedness or
         agreement, (B) the encumbrance or restriction is not materially more
         disadvantageous to the holders of the notes than is customary in
         comparable financings (as determined by our company) and (C) our
         company determines that any such encumbrance or restriction will not
         materially affect our company's ability to make principal or interest
         payments on the notes. Nothing contained in this "Limitation on
         Dividend and Other Payment Restrictions Affecting Restricted
         Subsidiaries" covenant shall prevent our company or any Restricted
         Subsidiary from (i) creating, incurring, assuming or suffering to exist
         any Liens otherwise permitted in the "Limitation on Liens" covenant or
         (ii) restricting the sale or other disposition of property or assets of
         our company or any of its Restricted Subsidiaries that secure
         Indebtedness of our company or any of its Restricted Subsidiaries.

  Limitation on the Issuance and Sale of Capital Stock of Restricted
Subsidiaries

     We will not sell, and will not permit any Restricted Subsidiary, directly
or indirectly, to issue or sell, any shares of Capital Stock of a Restricted
Subsidiary (including options, warrants or other rights to purchase shares of
such Capital Stock) except

     (1) to our company or a Wholly-Owned Restricted Subsidiary;

     (2) issuances of director's qualifying shares or sales to foreign nationals
         of shares of Capital Stock of foreign Restricted Subsidiaries, to the
         extent required by applicable law;

     (3) if, immediately after giving effect to such issuance or sale, such
         Restricted Subsidiary would no longer constitute a Restricted
         Subsidiary and any Investment in such Person remaining after giving
         effect to such issuance or sale would have been permitted to be made
         under the "Limitation on Restricted Payments" covenant if made on the
         date of such issuance or sale; or

     (4) the sale of common stock of Restricted Subsidiaries that is not
         Disqualified Stock, if the proceeds of such issuance or sale are
         applied in accordance with clause (A) or (B) of the first paragraph of
         the "Limitation on Asset Sales" covenant or

     (5) the transfer of up to 3% of the common stock of each Restricted
         Subsidiary to employees of such Restricted Subsidiary in connection
         with such employment.

  Limitation on Issuances of Guarantees by Restricted Subsidiaries

     We will not permit any Restricted Subsidiary, directly or indirectly, to
Guarantee any of our Indebtedness which is pari passu with or subordinate in
right of payment to the notes ("Guaranteed Indebtedness"), unless

     (1) such Restricted Subsidiary simultaneously executes and delivers a
         supplemental indenture to the Indenture providing for a Guarantee (a
         "Subsidiary Guarantee") of payment of the notes by such Restricted
         Subsidiary and

     (2) such Restricted Subsidiary waives and will not in any manner whatsoever
         claim or take the benefit or advantage of, any rights of reimbursement,
         indemnity or subrogation or any other rights against our company or any
         other Restricted Subsidiary as a result of any payment by such
         Restricted Subsidiary under its Subsidiary Guarantee; provided that
         this paragraph shall not be applicable to any Guarantee of any
         Restricted Subsidiary that existed at the time such Person became a
         Restricted Subsidiary and was not Incurred in connection with, or in
         contemplation of, such Person becoming a Restricted Subsidiary. If the
         Guaranteed Indebtedness is (A) pari passu with the notes, then the
         Guarantee of such Guaranteed Indebtedness shall be pari passu with, or
         subordinated to, the Subsidiary Guarantee or (B) subordinated to the
         notes, then the Guarantee of such Guaranteed Indebtedness shall be
         subordinated to the Subsidiary Guarantee at least to the extent that
         the Guaranteed Indebtedness is subordinated to the notes.

     Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary may provide by its terms that it shall be automatically and
unconditionally released and discharged upon

     (1) any sale, exchange or transfer, to any Person not an Affiliate of our
         company, of all of our company's and each Restricted Subsidiary's
         Capital Stock in, or all or substantially all the assets of, such
         Restricted Subsidiary (which sale, exchange or transfer is not
         prohibited by the Indenture) or

     (2) the release or discharge of the Guarantee which resulted in the
         creation of such Subsidiary Guarantee, except a discharge or release by
         or as a result of payment under such Guarantee.

  Limitation on Transactions with Shareholders and Affiliates

     We will not, and will not permit any Restricted Subsidiary to, directly or
indirectly, enter into, renew or extend any transaction (including, without
limitation, the purchase, sale, lease or exchange of property or assets, or the

class of Capital Stock of our company or with any Affiliate of our company or
any Restricted Subsidiary, except upon fair and reasonable terms no less
favorable to our company or such Restricted Subsidiary than could be obtained,
at the time of such transaction or, if such transaction is pursuant to a written
agreement, at the time of the execution of the agreement providing therefor, in
a comparable arm's-length transaction with a Person that is not such a holder or
an Affiliate.

     The foregoing limitation does not limit, and shall not apply to:

     (1) transactions (A) approved by a majority of the disinterested members of
         the Board of Directors or (B) for which our company or a Restricted
         Subsidiary delivers to the Trustee a written opinion of a nationally
         recognized U.S. investment banking firm stating that the transaction is
         fair to our company or such Restricted Subsidiary from a financial
         point of view;

     (2) any transaction solely between our company and any of its Wholly-Owned
         Restricted Subsidiaries or solely between Wholly-Owned Restricted
         Subsidiaries;

     (3) the payment of reasonable and customary regular fees to directors of
         our company who are not employees of our company;

     (4) any payments or other transactions pursuant to any tax-sharing
         agreement between our company and any other Person with which our
         company files a consolidated tax return or with which our company is
         part of a consolidated group for tax purposes; or

     (5) any Restricted Payments not prohibited by the "Limitation on Restricted
         Payments" covenant (other than pursuant to clause (4) of the definition
         or "Permitted Investment"). Notwithstanding the foregoing, any
         transaction or series of related transactions covered by the first
         paragraph of this "Limitation on Transactions with Shareholders and
         Affiliates" covenant and not covered by clauses (2) through (5) of this
         paragraph, the aggregate amount of which exceeds $1 million in value,
         must be approved or determined to be fair in the manner provided for in
         clause (1)(A) or (B) above.

  Limitation on Liens

     We will not, and will not permit any Restricted Subsidiary to, create,
incur, assume or suffer to exist any Lien on any of its assets or properties of
any character (including, without limitation, licenses), or any shares of
Capital Stock or Indebtedness of any Restricted Subsidiary, without making
effective provision for all of the notes and all other amounts due under the
Indenture to be directly secured equally and ratably with (or, if the obligation
or liability to be secured by such Lien is subordinated in right of payment to
the notes, prior to) the obligation or liability secured by such Lien.

     The foregoing limitation does not apply to

     (1) Liens existing on the Closing Date;

     (2) Liens granted after the Closing Date on any assets or Capital Stock of
         our company or its Restricted Subsidiaries created in favor of the
         holders;

     (3) Liens with respect to the assets of a Restricted Subsidiary granted by
         such Restricted Subsidiary to our company or a Wholly-Owned Restricted
         Subsidiary to secure Indebtedness owing to our company or such other
         Restricted Subsidiary;

     (4) Liens securing Indebtedness which is Incurred to refinance secured
         Indebtedness which is permitted to be Incurred under clause (3) of the
         second paragraph of the "Limitation on Indebtedness" covenant; provided
         that such Liens do not extend to or cover any property or assets of our
         company or any Restricted Subsidiary other than the property or assets
         securing the Indebtedness being refinanced;

     (5) Liens on the Capital Stock of, or any property or assets of, a
         Restricted Subsidiary securing Indebtedness of such Restricted
         Subsidiary permitted under the "Limitation on Indebtedness" covenant;

                                       115
<PAGE>   116

     (6) Liens on the Capital Stock of Restricted Subsidiaries securing up to
         $100.0 million of Indebtedness Incurred under clause (7) of the second
         paragraph of the "Limitation on Indebtedness" covenant;

     (7) Liens on assets having a fair market value equal to no more than 10% of
         the fair market value of the Adjusted Consolidated Net Tangible Assets
         that are not subject to Liens on the Closing Date; or

     (8) Permitted Liens.

  Limitation on Sale-Leaseback Transactions

     We will not, and will not permit any Restricted Subsidiary to, enter into
any sale-leaseback transaction involving any of its assets or properties whether
now owned or hereafter acquired, whereby our company or a Restricted Subsidiary
sells or transfers such assets or properties and then or thereafter leases such
assets or properties or any part thereof or any other assets or properties which
our company or such Restricted Subsidiary, as the case may be, intends to use
for substantially the same purpose or purposes as the assets or properties sold
or transferred.

     The foregoing restriction does not apply to any sale-leaseback transaction
if

     (1) the lease is for a period, including renewal rights, of not in excess
         of three years;

     (2) the lease secures or relates to industrial revenue or pollution control
         bonds;

     (3) the transaction is solely between our company and any Wholly-Owned
         Restricted Subsidiary or solely between Wholly-Owned Restricted
         Subsidiaries; or

     (4) our company or such Restricted Subsidiary, within 12 months after the
         sale or transfer of any assets or properties is completed, applies an
         amount not less than the net proceeds received from such sale in
         accordance with clause (A) or (B) of the first paragraph of the
         "Limitation on Asset Sales" covenant described below.

  Limitation on Asset Sales

     We will not, and will not permit any Restricted Subsidiary to, consummate
any Asset Sale, unless

     (1) the consideration received by our company or such Restricted Subsidiary
         is at least equal to the fair market value of the assets sold or
         disposed of and


     (2) at least 75% of the consideration received consists of cash or
         Temporary Cash Investments; provided, however, that this clause (2)
         shall not apply to long-term assignments in capacity in a
         telecommunications network. In the event and to the extent that the Net
         Cash Proceeds received by our company or any of its Restricted
         Subsidiaries from one or more Asset Sales occurring on or after the
         Closing Date in any period of 12 consecutive months exceed 10% of
         Adjusted Consolidated Net Tangible Assets (determined as of the date
         closest to the commencement of such 12-month period for which a
         consolidated balance sheet of our company and its Subsidiaries has been
         filed with the Commission pursuant to the "Commission Reports and
         Reports to Holders" covenant), then our company shall or shall cause
         the relevant Restricted Subsidiary to (1) within 12 months after the
         date Net Cash Proceeds so received exceed 10% of Adjusted Consolidated
         Net Tangible Assets (A) apply an amount equal to such excess Net Cash
         Proceeds to permanently repay unsubordinated Indebtedness of our
         company, or any Restricted Subsidiary providing a Subsidiary Guarantee
         pursuant to the "Limitation on Issuances of Guarantees by Restricted
         Subsidiaries" covenant described above or Indebtedness of any other
         Restricted Subsidiary, in each case owing to a Person other than our
         company or any of its Restricted Subsidiaries or (B) invest an equal
         amount, or the amount not so applied pursuant to clause (A) (or enter
         into a definitive agreement committing to so invest within 12 months
         after the date of such agreement), in property or assets (other than
         current assets) of a nature or type or that are used in a business (or
         in a company having property and assets of a nature or type, or engaged
         in a business) similar or related to the nature or type of the property
         and assets of, or the business of, our company and its Restricted
         Subsidiaries existing on the date of


                                       116
<PAGE>   117

         such investment (as determined in good faith by the Board of Directors,
         whose determination shall be conclusive and evidenced by a Board
         Resolution) and (2) apply (no later than the end of the 12-month period
         referred to in clause (1)) such excess Net Cash Proceeds (to the extent
         not applied pursuant to clause (1)) as provided in the following
         paragraph of this "Limitation on Asset Sales" covenant. The amount of
         such excess Net Cash Proceeds required to be applied (or to be
         committed to be applied) during such 12-month period as set forth in
         clause (1) of the preceding sentence and not applied as so required by
         the end of such period shall constitute "Excess Proceeds."

     If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
"Limitation on Asset Sales" covenant totals at least $5 million, our company
must commence, not later than the fifteenth Business Day of such month, and
consummate an Offer to Purchase from the holders on a pro rata basis an
aggregate principal amount of notes equal to the Excess Proceeds on such date,
at a purchase price equal to 101% of the principal amount of the notes, plus
accrued interest (if any) to the Payment Date.

REPURCHASE OF NOTES UPON A CHANGE OF CONTROL

     We must commence, within 30 days of the occurrence of a Change of Control,
and consummate an Offer to Purchase for all notes then outstanding, at a
purchase price equal to 101% of the principal amount of the notes on the
relevant Payment Date, plus, accrued interest (if any) to the Payment Date.
Prior to the mailing of the notice to holders commencing such Offer to Purchase,
but in any event within 30 days following any Change of Control, our company
covenants to

     (1) repay in full all indebtedness of our company that would prohibit the
         repurchase of the notes pursuant to such Offer to Purchase or

     (2) obtain any requisite consents under instruments governing any such
         indebtedness of our company to permit the repurchase of the notes. The
         Company shall first comply with the covenant in the preceding sentence
         before it shall be required to repurchase notes pursuant to this
         "Repurchase of Notes upon a Change of Control" covenant.

     If our company is unable to repay all of its indebtedness that would
prohibit repurchase of the notes or is unable to obtain the consents of the
holders of indebtedness, if any, of our company outstanding at the time of a
Change of Control whose consent would be so required to permit the repurchase of
notes, then our company will have breached such covenant. This breach will
constitute an Event of Default under the Indenture if it continues for a period
of 30 consecutive days after written notice is given to our company by the
Trustee or the holders of at least 25% in aggregate principal amount of the
notes outstanding. In addition, the failure by our company to repurchase the
notes at the conclusion of the Offer to Purchase will constitute an Event of
Default without any waiting period or notice requirements.


COMMISSION REPORTS AND REPORTS TO HOLDERS



     Whether or not we are required to file reports with the Commission, if any
notes are outstanding, we will file with the Commission all such reports and
other information as we would be required to file with the Commission by
Sections 13(a) or 15(d) under the Securities Exchange Act of 1934, as amended,
if we were subject thereto, unless we will be unable to effect such filing or
the Commission will refuse to accept such filing. We will supply the Trustee and
each holder or will supply to the Trustee for forwarding to each holder, without
cost to such holder, copies of such reports and other information, whether or
not we will be unable to effect such filing or the Commission refuses to accept
such filing.


EVENTS OF DEFAULT

     The following events will be defined as "Events of Default" in the
Indenture:

     (a) default in the payment of principal of (or premium, if any, on) any
         note when the same becomes due and payable at maturity, upon
         acceleration, redemption or otherwise;

                                       117
<PAGE>   118

     (b) default in the payment of interest on any note when the same becomes
         due and payable, and such default continues for a period of 30 days;

     (c) our company defaults in the performance of or breaches any other
         covenant or agreement of our company in the Indenture or under the
         notes and such default or breach continues for a period of 30
         consecutive days after written notice by the Trustee or the holders of
         25% or more in aggregate principal amount of the notes;

     (d) there occurs with respect to any issue or issues of Indebtedness of our
         company or any Significant Subsidiary having an outstanding principal
         amount of $5 million or more in the aggregate for all such issues of
         all such Persons, whether such Indebtedness now exists or shall
         hereafter be created, (I) an event of default that has caused the
         holder thereof to declare such Indebtedness to be due and payable prior
         to its Stated Maturity and such Indebtedness has not been discharged in
         full or such acceleration has not been rescinded or annulled within 30
         days of such acceleration and/or (II) the failure to make a principal
         payment at the final (but not any interim) fixed maturity and such
         defaulted payment shall not have been made, waived or extended within
         30 days of such payment default;

     (e) any final judgment or order (not covered by insurance) for the payment
         of money in excess of $5 million in the aggregate for all such final
         judgments or orders against all such Persons (treating any deductibles,
         self-insurance or retention as not so covered) shall be rendered
         against our company or any Significant Subsidiary and shall not be paid
         or discharged, and either (A) an enforcement proceeding shall have been
         commenced by a creditor upon such judgment or order or (B) there shall
         be any period of 30 consecutive days following entry of the final
         judgment or order that causes the aggregate amount for all such final
         judgments or orders outstanding and not paid or discharged against all
         such Persons to exceed $5 million during which a stay of enforcement of
         such final judgment or order, by reason of a pending appeal or
         otherwise, shall not be in effect;

     (f) a court having jurisdiction in the premises enters a decree or order
         for (A) relief in respect of our company or any Significant Subsidiary
         in an involuntary case under any applicable bankruptcy, insolvency or
         other similar law now or hereafter in effect, (B) appointment of a
         receiver, liquidator, assignee, custodian, trustee, sequestrator or
         similar official of our company or any Significant Subsidiary or for
         all or substantially all of the property and assets of our company or
         any Significant Subsidiary or (C) the winding up or liquidation of the
         affairs of our company or any Significant Subsidiary and, in each case,
         such decree or order shall remain unstayed and in effect for a period
         of 30 consecutive days; or

     (g) our company or any Significant Subsidiary (A) commences a voluntary
         case under any applicable bankruptcy, insolvency or other similar law
         now or hereafter in effect, or consents to the entry of an order for
         relief in an involuntary case under any such law, (B) consents to the
         appointment of or taking possession by a receiver, liquidator,
         assignee, custodian, trustee, sequestrator or similar official of our
         company or any Significant Subsidiary or for all or substantially all
         of the property and assets of our company or any Significant Subsidiary
         or (C) effects any general assignment for the benefit of creditors.

     If an Event of Default (other than an Event of Default specified in clause
(f) or (g) above that occurs with respect to our company) occurs and is
continuing under the Indenture, the Trustee or the holders of at least 25% in
aggregate principal amount of the notes then outstanding, by written notice to
our company (and to the Trustee if such notice is given by the holders), may,
and the Trustee at the request of such holders shall, declare the principal of,
premium, if any, and accrued interest on the notes to be immediately due and
payable. Upon a declaration of acceleration, such principal of, premium, if any,
and accrued interest on the notes shall be immediately due and payable. In the
event of a declaration of acceleration because an Event of Default set forth in
clause (d) above has occurred and is continuing, such declaration of
acceleration shall be automatically rescinded and annulled if the event of
default triggering such Event of Default pursuant to clause (d) shall be
remedied or cured by our company or the relevant Significant Subsidiary or
waived by the holders of the relevant Indebtedness within 60 days after the
declaration of acceleration with respect thereto,
                                       118
<PAGE>   119

and no other Defaults under the Indenture have occurred and are continuing after
giving pro forma effect to such remedy, cure or waiver. If an Event of Default
specified in clause (f) or (g) above occurs with respect to our company, the
principal of, premium, if any, and accrued interest on the notes then
outstanding shall ipso facto become and be immediately due and payable without
any declaration or other act on the part of either Trustee or any holder. The
holders of at least a majority in principal amount of the outstanding notes by
written notice to the Trustee, may waive all past defaults and rescind and annul
a declaration of acceleration and its consequences if (i) all existing Events of
Default, other than the nonpayment of the principal of, premium, if any, and
interest on the notes that have become due solely by such declaration of
acceleration, have been cured or waived and (ii) the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction. For
information as to the waiver of defaults, see "-- Modification and Waiver."

     The holders of at least a majority in aggregate principal amount of the
outstanding notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the Trustee
in personal liability, or that the Trustee determines in good faith may be
unduly prejudicial to the rights of holders of notes not joining in the giving
of such direction and may take any other action it deems proper that is not
inconsistent with any such direction received from holders of notes. A holder
may not pursue any remedy with respect to the Indenture or the notes unless:

     (1) the holder gives the Trustee written notice of a continuing Event of
         Default;

     (2) the holders of at least 25% in aggregate principal amount of
         outstanding notes make a written request to the Trustee to pursue the
         remedy;

     (3) such holder or holders offer the Trustee indemnity satisfactory to the
         Trustee against any costs, liability or expense;

     (4) the Trustee does not comply with the request within 60 days after
         receipt of the request and the offer of indemnity; and

     (5) during such 60-day period, the holders of a majority in aggregate
         principal amount of the outstanding notes do not give the Trustee a
         direction that is inconsistent with the request. However, such
         limitations do not apply to the right of any holder of a note to
         receive payment of the principal of, premium, if any, or interest on,
         such note or to bring suit for the enforcement of any such payment, on
         or after the due date expressed in the notes, which right shall not be
         impaired or affected without the consent of the holder.

     The Indenture will require certain officers of our company to certify, on
or before a date not more than 90 days after the end of each fiscal year, that a
review has been conducted of the activities of our company and its Restricted
Subsidiaries and our company's, and its Restricted Subsidiaries' performance
under the Indenture and that our company has fulfilled all obligations
thereunder, or, if there has been a default in the fulfillment of any such
obligation, specifying each such default and the nature and status thereof. The
Company will also be obligated to notify the Trustee of any default or defaults
in the performance of any covenants or agreements under the Indenture.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     The Company will not consolidate with, merge with or into, or sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its property
and assets (as an entirety or substantially an entirety in one transaction or a
series of related transactions) to, any Person (other than a consolidation or
merger with or into a Wholly-Owned Restricted Subsidiary with a positive net
worth; provided that, in connection with any such merger or consolidation, no
consideration (other than Common Stock in the surviving Person or our company
shall be issued or distributed to the stockholders of our company) or permit any
Person to merge with or into our company unless:

                                       119
<PAGE>   120

     (1) our company shall be the continuing Person, or the Person (if other
         than our company) formed by such consolidation or into which our
         company is merged or that acquired or leased such property and assets
         of our company shall be a corporation organized and validly existing
         under the laws of the United States of America or any jurisdiction
         thereof and shall expressly assume, by a supplemental indenture,
         executed and delivered to the Trustees, all of the obligations of our
         company on all of the notes and under the Indenture;

     (2) immediately after giving effect to such transaction, no Default or
         Event of Default shall have occurred and be continuing;

     (3) immediately after giving effect to such transaction on a pro forma
         basis, our company or any Person becoming the successor obligor of the
         notes shall have a Consolidated Net Worth equal to or greater than the
         Consolidated Net Worth of our company immediately prior to such
         transaction;

     (4) immediately after giving effect to such transaction on a pro forma
         basis our company, or any Person becoming the successor obligor of the
         notes, as the case may be, could Incur at least $1.00 of Indebtedness
         under the first paragraph of the "Limitation on Indebtedness" covenant;
         provided that this clause (4) shall not apply to (x) a consolidation,
         merger or sale of all (but not less than all) of the assets of our
         company if all Liens and Indebtedness of our company or any Person
         becoming the successor obligor on the notes, as the case may be, and
         its Restricted Subsidiaries outstanding immediately after such
         transaction would, if Incurred at such time, have been permitted to be
         Incurred (and all such Liens and Indebtedness, other than Liens and
         Indebtedness of our company and its Restricted Subsidiaries outstanding
         immediately prior to the transaction, shall be deemed to have been
         Incurred) for all purposes of the Indenture or (y) a consolidation,
         merger or sale of all or substantially all of the assets of our company
         if immediately after giving effect to such transaction on a pro forma
         basis, our company or any Person becoming the successor obligor of the
         notes shall have an Indebtedness to EBITDA Ratio equal to or less than
         the Indebtedness to EBITDA Ratio of our company immediately prior to
         such transaction; and

     (5) our company delivers to the Trustee an Officers' Certificate (attaching
         the arithmetic computations to demonstrate compliance with clauses (3)
         and (4) above) and Opinion of Counsel, in each case stating that such
         consolidation, merger or transfer and such supplemental indenture
         complies with this provision and that all conditions precedent provided
         for herein relating to such transaction have been complied with;
         provided, however, that clauses (3) and (4) above do not apply if, in
         the good faith determination of the Board of Directors of our company,
         whose determination shall be evidenced by a Board Resolution, the
         principal purpose of such transaction is to change the state of
         incorporation of our company; and provided further that any such
         transaction shall not have as one of its purposes the evasion of the
         foregoing limitations.

DEFEASANCE

     Defeasance and Discharge.  The Indenture will provide that our company will
be deemed to have paid and will be discharged from any and all obligations in
respect of the notes on the 123rd day after the deposit referred to below, and
the provisions of the Indenture will no longer be in effect with respect to the
notes (except for, among other matters, certain obligations to register the
transfer or exchange of the notes, to replace stolen, lost or mutilated notes,
to maintain paying agencies and to hold monies for payment in trust) if, among
other things,

     (A) our company has deposited with the Trustee, in trust, money and/or U.S.
         Government Obligations that through the payment of interest and
         principal in respect thereof in accordance with their terms will
         provide money in an amount sufficient to pay the principal of, premium,
         if any, and accrued interest on the notes on the Stated Maturity of
         such payments in accordance with the terms of the Indenture and the
         notes,

     (B) our company has delivered to the Trustee (1) either (x) an Opinion of
         Counsel to the effect that holders will not recognize income, gain or
         loss for federal income tax purposes as a result of our

                                       120
<PAGE>   121

         company's exercise of its option under this "Defeasance" provision and
         will be subject to federal income tax on the same amount and in the
         same manner and at the same times as would have been the case if such
         deposit, defeasance and discharge had not occurred, which Opinion of
         Counsel must be based upon (and accompanied by a copy of) a ruling of
         the Internal Revenue Service to the same effect unless there has been a
         change in applicable federal income tax law after the Closing Date such
         that a ruling is no longer required or (y) a ruling directed to the
         Trustee received from the Internal Revenue Service to the same effect
         as the aforementioned Opinion of Counsel and (2) an Opinion of Counsel
         to the effect that the creation of the defeasance trust does not
         violate the Investment Company Act of 1940 and after the passage of 123
         days following the deposit, the trust fund will not be subject to the
         effect of Section 547 of the United States Bankruptcy Code or Section
         15 of the New York Debtor and Creditor Law,


     (C) immediately after giving effect to such deposit on a pro forma basis,
         no Event of Default, or event that after the giving of notice or lapse
         of time or both would become an Event of Default, shall have occurred
         and be continuing on the date of such deposit or during the period
         ending on the 123rd day after the date of such deposit, and such
         deposit shall not result in a breach or violation of, or constitute a
         default under, any other agreement or instrument to which our company
         or any of its Subsidiaries is a party or by which our company or any of
         its Subsidiaries is bound and


     (D) if at such time the notes are listed on a national securities exchange,
         our company has delivered to the Trustee an Opinion of Counsel to the
         effect that the notes will not be delisted as a result of such deposit,
         defeasance and discharge.

     Defeasance of Certain Covenants and Certain Events of Default. The
Indenture further will provide that the provisions of the Indenture will no
longer be in effect with respect to clauses (3) and (4) under "Consolidation,
Merger and Sale of Assets" and all the covenants described herein under
"Covenants," and clause (c) under "Events of Default" with respect to such
clauses (3) and (4) under "Consolidation, Merger and Sale of Assets," and
clauses (d) and (e) under "Events of Default" shall be deemed not to be Events
of Default upon, among other things, the deposit with the Trustee, in trust, of
money and/or U.S. Government Obligations that through the payment of interest
and principal in respect thereof in accordance with their terms will provide
money in an amount sufficient to pay the principal of, premium, if any, and
accrued interest on the notes on the Stated Maturity of such payments in
accordance with the terms of the Indenture and the notes, the satisfaction of
the provisions described in clauses (B)(2), (C) and (D) of the preceding
paragraph and the delivery by our company to the Trustee of an Opinion of
Counsel to the effect that, among other things, the holders will not recognize
income, gain or loss for federal income tax purposes as a result of such deposit
and defeasance of certain covenants and Events of Default and will be subject to
federal income tax on the same amount and in the same manner and at the same
times as would have been the case if such deposit and defeasance had not
occurred.

     Defeasance and Certain Other Events of Default.  If our company exercises
its option to omit compliance with certain covenants and provisions of the
Indenture with respect to the notes as described in the immediately preceding
paragraph and the notes are declared due and payable because of the occurrence
of an Event of Default that remains applicable, the amount of money and/or U.S.
Government Obligations on deposit with the Trustee will be sufficient to pay
amounts due on the notes at the time of their Stated Maturity but may not be
sufficient to pay amounts due on the notes at the time of the acceleration
resulting from such Event of Default. However, our company will remain liable
for such payments.

MODIFICATION AND WAIVER

     Modifications and amendments of an Indenture may be made by our company and
the Trustee with the consent of the holders of not less than a majority in
aggregate principal amount of the outstanding notes; provided, however, that no
such modification or amendment may, without the consent of each holder affected
thereby,

     (1) change the Stated Maturity of the principal of, or any installment of
         interest on, any note,

                                       121
<PAGE>   122

     (2) reduce the principal amount of, or premium, if any, or interest on, any
         note, or adversely affect any right of repayment at the option of any
         holder of any note,

     (3) change the place or currency of payment of principal of, or premium, if
         any, or interest on, any note,

     (4) impair the right to institute suit for the enforcement of any payment
         on or after the Stated Maturity (or, in the case of a redemption, on or
         after the Redemption Date) of any note,

     (5) reduce the above-stated percentage of outstanding notes the consent of
         whose holders is necessary to modify, supplement or amend the
         Indenture,


     (6) waive a default in the payment of principal of, premium, if any, or
         interest on the notes or


     (7) reduce the percentage or aggregate principal amount of outstanding
         notes the consent of whose holders is necessary for waiver of
         compliance with certain provisions of the Indenture or for waiver of
         certain defaults.

NO PERSONAL LIABILITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS, DIRECTORS, OR
EMPLOYEES

     The Indenture provides that no recourse for the payment of the principal
of, premium, if any, or interest on any of the notes or for any claim based
thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of our company in the Indenture, or in any of
the notes or because of the creation of any Indebtedness represented thereby,
shall be had against any incorporator, stockholder, officer, director, employee
or controlling person of our company or of any successor Person thereof. Each
holder, by accepting the notes, waives and releases all such liability.

CONCERNING THE TRUSTEE

     The Indenture provides that, except during the continuance of a Default,
the Trustee will not be liable, except for the performance of such duties as are
specifically set forth in such Indenture. If an Event of Default has occurred
and is continuing, the Trustee will use the same degree of care and skill in its
exercise of the rights and powers vested in it under the Indenture as a prudent
person would exercise under the circumstances in the conduct of such person's
own affairs.

     The Indenture and provisions of the Trust Indenture Act of 1939, as
amended, incorporated by reference therein contain limitations on the rights of
the Trustee, should it become a creditor of our company, to obtain payment of
claims in certain cases or to realize on certain property received by it in
respect of any such claims, as security or otherwise. The Trustee is permitted
to engage in other transactions; provided, however, that if it acquires any
conflicting interest, it must eliminate such conflict or resign.

GOVERNING LAW AND SUBMISSION TO JURISDICTION

     The notes and the Indenture will be governed by the laws of the State of
New York. We will submit to the jurisdiction of the U.S. federal and New York
state courts located in the City of New York for purposes of all legal actions
and proceedings instituted in connection with the notes and the Indenture.

CURRENCY INDEMNITY

     U.S. dollars are the sole currency of account and payment for all sums
payable by us under or in connection with the notes, including damages. Any
amount received or recovered in a currency other than dollars (whether as a
result of, or of the enforcement of, a judgment or order of a court of any
jurisdiction, in the winding-up or dissolution of our company or otherwise) by
any holder of a note in respect of any sum expressed to be due to it from our
company shall only constitute a discharge to our company to the extent of the
dollar amount which the recipient is able to purchase with the amount so
received or recovered in that other currency on the date of that receipt or
recovery (or, if it is not practicable to make that purchase on that date, on
the first date on which it is practicable to do so). If that dollar amount is
less than the dollar amount expressed to be due to the recipient under any note,
we will indemnify the recipient against any loss sustained by it as a result. In
any event, we will indemnify the recipient against the cost of making any such
purchase.
                                       122
<PAGE>   123

For the purposes of this paragraph, it will be sufficient for the holder of a
note to certify in a satisfactory manner (indicating the sources of information
used) that it would have suffered a loss had an actual purchase of dollars been
made with the amount so received in that other currency on the date of receipt
or recovery (or, if a purchase of dollars on such date had not been practicable,
on the first date on which it would have been practicable, it being required
that the need for a change of date be certified in the manner mentioned above).
These indemnities constitute a separate and independent obligation from our
Company's other obligations, shall give rise to a separate and independent cause
of action, shall apply irrespective of any indulgence granted by any holder of a
note and shall continue in full force and effect despite any other judgment,
order, claim or proof for a liquidated amount in respect of any sum due under
any note.

BOOK-ENTRY; DELIVERY AND FORM


     Except as set forth below, the new notes to be issued upon the consummation
of the Exchange Offer will be issued in the form of a single global note. The
global note will be deposited with the Trustee as custodian for, and registered
in the name of, a nominee of DTC. Except as set forth below, the global note may
be transferred, in whole and not in part, only to the DTC or another nominee of
the DTC. Ownership of beneficial interests in a global note will be limited to
persons who have accounts with DTC (referred to as "participants") or persons
who hold interests through participants. Ownership of beneficial interests in a
global note will be shown on, and the transfer of that ownership will be
effected only through, records maintained by DTC or its nominee (with respect to
interests of participants) and the records of participants (with respect to
interests of persons other than participants).



     Investors may also hold their book-entry interests in the global note
through Euroclear or Cedelbank or another such organization that is a
participant. Euroclear and Cedelbank will hold book-entry interests in the
global note on behalf of their account holders through securities accounts in
the respective account holders' names on Euroclear's and Cedelbank's respective
book-entry registration and transfer systems, and Euroclear and Cedelbank will
in turn hold such book entry interests in the global note in accounts in their
respective names on the books of DTC.


     So long as DTC, or its nominee, is the registered owner or holder of a
global note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the notes represented by such global note for all
purposes under the Indenture and the notes. You will not be able to transfer
your interest in a global note except in accordance with DTC's applicable
procedures in addition to those provided for under the Indenture.

     Payments of the principal of, and interest on, a global note will be made
to DTC or its nominee, as the case may be, as the registered owner thereof.
Neither our company, the Trustee nor any Paying Agent will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a global note or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

     We expect that DTC or its nominee, upon receipt of any payment of principal
or interest in respect of a global note, will credit participants' accounts with
payments in amounts proportionate to their respective beneficial interests in
the principal amount of such global note as shown on the records of DTC or its
nominee. We also expect that payments by participants to owners of beneficial
interests in such global note held through such participants will be governed by
standing instructions and customary practices, as is now the case with
securities held for the accounts of customers registered in the names of
nominees for such customers. Such payments will be the responsibility of such
participants.

     Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same-day funds. Transfers
between participants in Euroclear and Cedel Bank will be effected in the
ordinary way in accordance with their respective rules and operating procedures.

     We expect that DTC will take any action permitted to be taken by a holder
of notes (including the presentation of notes for exchange as described below)
only at the direction of one or more participants to whose account the DTC
interests in a global note is credited and only in respect of such portion of
the aggregate principal amount of notes as to which such participant or
participants has or have given such

                                       123
<PAGE>   124

direction. However, if there is an event of default under the notes, DTC will
exchange the applicable global note for certificated notes, which it will
distribute to its participants and which may bear a legend containing certain
transfer restrictions.

     We understand that DTC is a limited purpose trust company organized under
the laws of the State of New York, a "banking organization" within the meaning
of New York Banking Law, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the Uniform Commercial Code and a "Clearing
Agency" registered pursuant to the provisions of Section 17A of the Exchange
Act. DTC was created to hold securities for its participants and facilitate the
clearance and settlement of securities transactions between participants through
electronic book-entry changes in accounts of its participants, thereby
eliminating the need for physical movement of certificates and certain other
organizations. Indirect access to the DTC system is available to others such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a participant, either directly or indirectly
("indirect participants").


     Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in a global note among participants of DTC,
they are under no obligation to perform or continue to perform these procedures,
and these procedures may be discontinued at any time. Neither our company nor
the Trustee will have any responsibility for the performance by DTC or its
respective participants or indirect participants of their respective obligations
under the rules and procedures governing their operations.


     If DTC is at any time unwilling or unable to continue as a depositary for
the global notes and a successor depositary is not appointed by our company
within 90 days, we will issue certificated notes, which may bear a legend
containing certain transfer restrictions in exchange for the global notes.
Holders of an interest in a global note may receive certificated notes, which
may bear a legend containing certain transfer restrictions in accordance with
the DTC's rules and procedures in addition to those provided for under the
Indenture.

LUXEMBOURG STOCK EXCHANGE LISTING


     We intend to apply to list the new notes on the Luxembourg Stock Exchange.
As long as the notes are listed on the Luxembourg Stock Exchange and the
exchange so requires, we will maintain a transfer and paying agent in
Luxembourg.


                                       124
<PAGE>   125

                              PLAN OF DISTRIBUTION


     Except as described below, a broker-dealer may not participate in the
exchange offer in connection with a distribution of the new notes. Each
broker-dealer that receives new notes for its own account pursuant to the
exchange offer must acknowledge that it will deliver a prospectus in connection
with any resale of the new notes by such broker-dealer. This prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of new notes received for its own account in exchange
for outstanding notes where those outstanding notes were acquired as a result of
market-making activities or other trading activities. We have agreed that for a
period of 180 days after the expiration date of the exchange offer, it will make
this prospectus, as amended or supplemented, available to any broker-dealer for
use in connection with any resale subject to the conditions described under "The
Exchange Offer -- Procedure for Tendering Old Notes."


     We will not receive any proceeds from any sale of the notes by
broker-dealers. New notes received by broker-dealers for their own account
pursuant to the exchange offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the new notes or a combination of those methods of
resale, at market prices prevailing at the time of resale, at prices related to
the prevailing market prices, or negotiated prices. Any resale may be made
directly to purchasers or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any broker-dealer
and/or the purchasers of any new notes. Any broker or dealer that participates
in a distribution of the new notes may be deemed to be an "underwriter" within
the meaning of the Securities Act of 1933, and any profit on the resale of new
notes and any commissions or concessions received by those persons may be deemed
to be underwriting compensation under the Securities Act of 1933. The Letter of
Transmittal states that by acknowledging that it will deliver and by delivering
a prospectus a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act of 1933.

     We have agreed to pay all expenses incident to the exchange offer other
than commissions or concessions of any brokers or dealers and expenses of
counsel for the holders of the new notes and will indemnify the holders of the
new notes, including any broker-dealers, against some liabilities, including
some liabilities under the Securities Act of 1933.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS


     The following general discussion summarizes certain of the principal
material United States federal income tax consequences of the exchange of the
old notes for the new notes, and the ownership and disposition of the new notes.
This discussion is a summary for general information only and does not consider
all aspects of United States federal income taxation that may be relevant to an
investor in light of that investor's particular circumstances. This discussion
deals only with notes purchased at their original offering price and held as
capital assets within the meaning of Section 1221 of the United States Internal
Revenue Code of 1986, as amended to the date hereof (the "Code"). This summary
does not address all of the tax consequences that may be relevant to a holder of
notes nor does it address the federal income tax consequences to holders subject
to special treatment under the United States federal income tax laws, such as
brokers or dealers in securities or currencies, certain securities traders,
tax-exempt entities, banks, thrifts, insurance companies, other financial
institutions, persons that hold notes as a position in a "straddle" or as part
of a "synthetic security," "hedging," "conversion" or other integrated
instrument, persons that have a "functional currency" other than the United
States dollar, investors in pass-through entities and certain United States
expatriates. Further, this summary does not address (i) the income tax
consequences to shareholders in or partners or beneficiaries of, a holder of the
notes, (ii) the United States federal alternative minimum tax consequences of
the purchase, ownership or disposition of the notes, or (iii) any state, local
or foreign tax consequences of the purchase, ownership, or disposition of the
notes.


     This discussion is based upon the Code, existing and proposed regulations
thereunder, and current administrative rulings and court decisions. All of the
foregoing are subject to change, possibly on a retroactive basis, and any such
change could affect the continuing validity of this discussion.

     PERSONS CONSIDERING THE EXCHANGE OFFER SHOULD CONSULT THEIR OWN TAX
ADVISORS CONCERNING THE APPLICATION OF UNITED STATES FEDERAL INCOME TAXES LAWS,
AS WELL AS THE LAWS OF ANY STATE, LOCAL, OR FOREIGN TAXING JURISDICTION.

     For purposes of this discussion, the term "United States holder" means a
beneficial owner of notes that for United States federal income tax purposes is

     - a citizen or resident of the United States

     - a corporation or partnership created or organized under the laws of the
       United States or any State thereof or the District of Columbia


     - an estate the income of which may be included in its gross income for
       United States federal income tax purposes without regard to its source


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

Certain United States federal income tax consequences relevant to a beneficial
owner of a note other than a United States holder, referred to herein as a
non-U.S. holder, are discussed separately below.

UNITED STATES HOLDERS

     The following discussion applies to you if you are a United States holder.

     Exchange Offer

     You will not recognize any taxable gain or loss on an exchange of notes for
new notes pursuant to the exchange offer. You will have the same tax basis and
holding period in the new notes as you had in the notes.

                                       126
<PAGE>   127

  Payments of Interest

     Stated interest paid or accrued on the notes generally will be taxable to
you as ordinary income at the time such interest is paid or accrued in
accordance with your method of accounting for United States federal income tax
purposes.

  Foreign Source


     At present, we believe that we are an "80/20 company" for United States
federal income tax purposes (as defined below), and therefore that interest
income on the notes generally will be treated as foreign source income for
United States federal income tax purposes. A U.S. corporation is an 80/20
company if at least 80 percent of its gross income during an applicable testing
period is, directly or through its subsidiaries, "active foreign business
income". However, the 80% test for active foreign business income is applied on
a periodic basis, and our operations and business plans may change in future
years. Therefore, while at present it appears that interest income on the notes
will be treated as foreign source income, we can give no assurance regarding
future treatment. In addition, special source rules will apply to interest paid
to certain holders related to our company.


  Repurchase Premium


     The notes may be redeemed prior to their stated maturity under certain
circumstances at our option or at your option or automatically upon the
occurrence of certain events. We believe that none of such redemption rights or
obligations are more likely than not to occur. Accordingly, under applicable
U.S. Treasury regulations, we do not intend to treat such redemption rights or
obligations as affecting the yield or tax treatment of the notes.



  Sale or Redemption of the Notes.



     When you dispose of a note by sale, exchange or redemption, you generally
will recognize gain or loss equal to the difference, if any, between (i) the
amount realized on the disposition (other than amounts attributable to accrued
and unpaid interest) and (ii) your tax basis in the note. Your tax basis in a
note generally will equal the cost of the note reduced by any payments other
than payments of stated interest made on the note. When a note is sold, disposed
of or redeemed between Interest Payment Dates, the portion of the amount
realized on the disposition that is attributable to interest accrued to the date
of sale must be reported as interest income by a cash method investor and an
accrual method investor that has not included the interest in income as it
accrued.



     If you hold a note is held as a capital asset, such gain or loss generally
will constitute capital gain or loss and will be long-term capital gain or loss
if you have held such note for longer than one year. Under current law, net
capital gains of individuals may be taxed at lower rates than items of ordinary
income. The ability of a United States holder to offset capital losses against
ordinary income is limited. Any gain or loss recognized by a United States
holder on the sale, redemption or retirement of a note generally will be treated
as income from sources within the United States or loss allocable to income from
sources within the United States for United States federal income tax purposes.


NON-U.S. HOLDERS

     The following discussion summarizes certain United States federal income
tax consequences relevant to a non-U.S. holder of a note. This discussion does
not deal with all aspects of United States federal income taxation that may be
relevant to any particular non-U.S. holder in light of that holder's personal
circumstances with respect to such holder's purchase, ownership or disposition
of the notes, including such holder holding the notes through a partnership. For
example, persons who are partners in foreign partnerships and beneficiaries of
foreign trusts or estates who are subject to United States federal income tax
because of their own status may be subject to United States federal income tax
even though the entity is not subject to such tax.

                                       127
<PAGE>   128


  Exchange Offer



     A non-U.S. holder will not recognize any taxable gain or loss for United
States federal income tax purposes on an exchange of old notes for new notes
pursuant to the exchange offer.


  Stated Interest on the Notes

     If we are an 80/20 company as described above, subject to the discussion of
backup withholding below, payments of stated interest on a note by our company
or any paying agent to a non-U.S. holder will not be subject to United States
federal income tax, including United States withholding tax, unless the holder
has an office or other fixed place of business in the United States to which the
interest is attributable and the interest is derived in the active conduct of a
banking, financing or similar business within the United States. Special rules
will apply to payments of interest to non-U.S. holders related to our company.


     If we are not an 80/20 company, then under current United States federal
income tax law, and subject to the discussion of backup withholding below,
payments of stated interest on a note by our company or any paying agent to a
non-U.S. holder will not be subject to withholding of United States federal
income tax if (i) such payment is effectively connected with a trade or business
within the United States by such non-U.S. holder, or (ii) both (a) the holder
does not actually or constructively own 10 percent or more of the combined
voting power of all classes of stock of our company and is not a controlled
foreign corporation related to our company through stock ownership and (b) the
non-U.S. holder as the beneficial owner of the note, or a financial institution
holding the note on behalf of such holder, provides a statement signed under
penalties of perjury that includes its name and address and certifies (on an IRS
Form W-8BEN or a substantially similar substitute form) that the beneficial
owner of the note is a non-U.S. holder in compliance with applicable
requirements. Interest on a note that is effectively connected with the conduct
of a trade or business in the United States by a non-U.S. holder, although
exempt from the withholding tax (assuming appropriate certification is
provided), generally will be subject to graduated United States federal income
tax on a net income basis as if such amounts were earned by a United States
Holder. Corporate non-U.S. holders receiving effectively connected interest may
also be subject to an additional branch profits tax.


  Sale or Redemption of Notes

     Except as described below and subject to the discussion concerning backup
withholding, a non-U.S. holder generally will not be subject to withholding of
United States federal income tax with respect to any gain realized upon the sale
or redemption of notes. Further, a non-U.S. holder generally will not be subject
to United States federal income tax with respect to any such gain unless (i) the
gain is effectively connected with a United States trade or business of such
Non-U.S. Person, (ii) subject to certain exceptions, the non-U.S. holder is an
individual who holds such notes as a capital asset and is present in the United
States for 183 days or more in the taxable year of the disposition, or (iii) the
non-U.S. holder is subject to tax pursuant to the provisions of United States
tax law applicable to certain United States expatriates.


     A non-U.S. holder will not recognize any taxable gain or loss on exchange
of notes for exchange notes pursuant to an exchange offer. As such, an
exchanging holder will have the same tax basis and holding period in the
exchange notes as the holder had in the notes.



  New Regulations Relating to Withholding and Information Reporting for Non-U.S.
Holders.



     The IRS recently issued final regulations relating to withholding and
information reporting (described below) with respect to payments made to
non-U.S. holders. The regulations generally apply to payments made after
December 31, 2000. However, withholding certificates that are valid under the
present rules on December 31, 2000 remain valid until the earlier of December
31, 2001 or the expiration date of the certificate under the present rules
(unless otherwise invalidated due to changes in the circumstances of the person
whose name is on the certificate).


     When effective, the new regulations will streamline and, in some cases,
alter the types of statements and information that must be furnished to claim a
reduced rate of withholding. The regulations also clarify the

                                       128
<PAGE>   129


duties of United States payors making payments to foreign persons and modify the
rules concerning withholding on payments made to non-U.S. holders through
foreign intermediaries. With some exceptions, the new regulations treat a
payment to a foreign partnership as a payment directly to the partners. It is
possible that our company and other withholding agents may request new
withholding exemptions forms from Non-United States Holders in order to qualify
for continued exemption from withholding under the New Regulations when they
become effective. Non-U.S. holders should consult their own tax advisors to
determine the effects of the application of the new regulations to their
particular circumstances.


INFORMATION REPORTING AND BACKUP WITHHOLDING


     In general, information reporting requirements will apply to payments made
on, and proceeds from the sale of, notes held by a noncorporate United States
holder within the United States. In addition, payments made on, and payments of
proceeds from the sale of such notes to a non-U.S. holder made to or through the
United States office of a broker or a broker that is a United States person, a
controlled foreign corporation for United States federal income tax purposes, a
foreign person 50% or more of whose gross income is effectively connected with a
United States trade or business for a specified three-year period or (in the
case of payments made after December 31, 2000) a foreign partnership with
certain connections to the United States are subject to information reporting
unless the holder thereof certifies as to its non-U.S. status or otherwise
establishes an exemption from information reporting and backup withholding.


     Payments made on, and proceeds from the sale of, notes held by a United
States holder may be subject to a "backup" withholding tax of 31% unless the
holder complies with certain identification or exemption requirements. Backup
withholding at a rate of 31% will apply to payments by our company or its agent
on notes held by non-U.S. holders and proceeds from the sale or other
disposition of such notes through certain brokers unless the non-U.S. holder
certifies to its Non-U.S. status or otherwise establishes entitlement to
exemption. A non-U.S. holder may certify to its Non-U.S. status and obtain
exemption from backup withholding by providing an IRS Form W-8BEN or a
substantially similar substitute form. Backup withholding may apply to any
payment if the broker has actual knowledge that a payee claiming non-U.S. status
is a United States holder. Any amounts so withheld will be allowed as a credit
against the holder's income tax liability, or refunded, provided the required
information is provided to the IRS.

     Non-U.S. holders of notes should consult their tax advisers regarding the
application of information reporting and backup withholding in their particular
situations, the availability of an exemption therefrom, and the procedure for
obtaining such an exemption, if available.

                                 LEGAL MATTERS

     The validity of the new notes offered hereby will be passed upon by Arnold
& Porter, Washington, D.C., U.S. counsel to IMPSAT.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Shareholders of IMPSAT Fiber Networks, Inc.:

     We have audited the accompanying consolidated balance sheets of IMPSAT
Fiber Networks, Inc. and its subsidiaries (the "Company") as of December 31,
1998 and 1999, and the related consolidated statements of operations,
comprehensive (loss) income, stockholders' equity (deficit) and of cash flows
for each of the three years in the period ended December 31, 1999. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

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

     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of the Company at December 31,
1998 and 1999, and the results of its operations and its cash flows for each of
the three years in the period ended December 31, 1999 in conformity with
accounting principles generally accepted in the United States of America.

     As discussed in Note 3 to the consolidated financial statements, the
Company changed its method of accounting for license and permit costs in 1998.

                         (IN THOUSANDS OF U.S. DOLLARS)

1. GENERAL

     IMPSAT Fiber Networks, Inc., a Delaware holding company (the "Company"), is
a leading provider of private telecommunications network services in Latin
America. The Company offers tailor-made, integrated telecommunications
solutions, with an emphasis on data transmission, for national and multinational
companies, financial institutions, governmental agencies and other business
customers. In addition, the Company is building an extensive pan-Latin American
high capacity fiber optic network (the "Broadband Network"). The Company expects
that the first phase of the Broadband Network (see Note 6), which will connect
points across Argentina and Brazil, will be completed by December 2000.

     The Company currently provides telecommunications and data services through
its advanced fiber optic, satellite and microwave telecommunications networks.
These networks consist of owned teleports, earth stations, fiber optic and
microwave links, and leased satellite and fiber optic links. The Company
operates 12 metropolitan area networks in some of the largest cities in Latin
America, including: Buenos Aires, Sao Paulo, Bogota and Caracas.

     The Company was formed in August 1994 for the purpose of combining
operating entities in Argentina, Colombia, and Venezuela, which were previously
controlled by common ownership. The original operating entity was established in
Argentina in 1990 under the name of IMPSAT S.A. ("IMPSAT Argentina").
Thereafter, operating entities were established in Colombia in 1992 ("IMPSAT
Colombia") and in Venezuela in 1993 ("IMPSAT Venezuela"). Other operating
subsidiaries have been created or acquired in Brazil, Chile, Ecuador, Mexico,
Peru, and the United States.

     The Company's operating subsidiaries and percentages owned by the Company
after the minority interest transactions described in Note 12 are as follows:

2. MERGERS AND ACQUISITIONS

     Impsat Brazil -- On June 1, 1998, the Company acquired from Nevasa Holdings
Limited ("Nevasa"), the Company's parent, 99.9% of the capital stock of IMPSAT
Comunicacoes Ltda. ("IMPSAT Brazil"), a Brazilian company, for approximately
$5.7 million. The purchase price for IMPSAT Brazil represented the total amount
of pre-operating and development costs and expenses incurred for IMPSAT Brazil
by Nevasa. IMPSAT Brazil was established by Nevasa and operates under a value
added telecommunications license permitting IMPSAT Brazil to lease satellite
capacity directly from EMBRATEL, Brazil's long-distance carrier, and sell
corporate private telecommunications network services (data, voice and video)
using terrestrial and satellite links to third parties. The acquisition, as is
the case for transactions among companies

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

under common control, has been accounted for in a manner similar to the pooling
of interests method of accounting, whereby all assets and liabilities have been
recorded at their historical carrying amounts and the acquisition was recorded
as if the transaction occurred on January 1, 1998. IMPSAT Brazil did not have
material operations in 1997 as it was in the pre-operating phase. Amounts paid
in excess of carrying value of the underlying net assets acquired were recorded
as a reduction of stockholders' deficit and are being amortized on a
straight-line basis over a period of 10 years.

     Mandic S.A. -- On April 20, 1998, the Company signed a definitive agreement
to purchase a 75.1% interest in Mandic BBS Planejamento e Informatica S.A.
("Mandic S.A."), a Brazilian Internet access provider, for approximately $9.8
million. The initial stage of the acquisition of Mandic S.A., pursuant to which
the Company acquired a 58.5% interest, was consummated on May 29, 1998, and the
remaining 16.6% interest was acquired during November 1998. The acquisition was
accounted for as a purchase. On July 28, 1999, the Company acquired the
remaining 24.9% interest in Mandic S.A. for $3.7 million. The Company merged
Mandic S.A. into Impsat Brazil on October 5, 1999 and Mandic S.A. ceased
operations.

     Framework Agreement with El Sitio -- On August 4, 1999, the Company entered
into a Framework Agreement with El Sitio, Inc. ("El Sitio") for the sale of the
Company's retail Internet businesses in Argentina, Brazil and Colombia for
approximately $21.5 million and the purchase of shares of El Sitio's 8%
convertible redeemable preferred stock for $21.5 million. In connection with
these transactions, El Sitio will enter into telecommunications services
agreements with IMPSAT Argentina, IMPSAT Brazil and IMPSAT Colombia under which
these entities will provide El Sitio with telecommunication networks to access
the Internet backbone. El Sitio, a British Virgin Islands corporation, is an
Internet content and Internet service provider headquartered in Argentina that
has other offices in Brazil, Mexico, Uruguay and the United States.

     On October 6, 1999, IMPSAT Brazil sold its retail Internet business for
$12.3 million to O Site Entretenimentos Ltda., a subsidiary of El Sitio. In
addition, on the same date, the Company acquired 1,756,677 shares of El Sitio's
8% convertible redeemable preferred stock for $12.3 million. IMPSAT Brazil
recorded a net gain on the sale of its retail Internet business of approximately
$8.9 million, which is included in other (expense) income, net, in the
accompanying 1999 statement of operations.

     On November 5, 1999, IMPSAT Argentina consummated the sale of its retail
Internet business to El Sitio for $6.2 million, of which $5.3 million was
received on that date with the remainder due in 24 equal monthly installments.
Simultaneously, the Company purchased 885,480 shares of El Sitio's 8%
convertible redeemable preferred stock for $6.2 million. On November 12, 1999,
the Company acquired an additional 428,458 shares of El Sitio's 8% convertible
redeemable preferred stock for $3.0 million. IMPSAT Argentina recorded a net
gain on the sale of its retail Internet business of approximately $5.0 million,
which is included in other (expense) income, net in the accompanying 1999
statement of operations. The Company and El Sitio expect to consummate the sale
of the Company's retail Internet business in Colombia to El Sitio during April
2000.


     Upon the consummation of El Sitio's initial public offering in December
1999, the shares of El Sitio's preferred stock were automatically converted into
15.4% of El Sitio's then outstanding common stock.


3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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


     Interim Financial Information -- The unaudited consolidated statements as
of March 31, 2000 and for the three months ended March 31, 1999 and 2000 have
been prepared on the same basis as the Company's audited consolidated financial
statements. In the opinion of management, the unaudited consolidated financial
statements include all adjustments (consisting only of normal recurring
adjustments) necessary to present

fairly the results for such period. The operating results for the three-month
periods ended March 31, 1999 and 2000 are not necessarily indicative of the
operating results to be expected for the full fiscal year or for any future
period.


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

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


     Revenue Recognition -- The Company provides services to its customers
pursuant to contracts, which range from six months to five years but generally
are for three years. The customer generally pays a monthly fee based on the
quantity and type of equipment installed. The fees stipulated in the contracts
are generally denominated in U.S. dollars equivalents. Services are billed on a
monthly, predetermined basis, which coincides with when the services are
rendered. No single customer accounted for greater than 10% of total net revenue
from services for the years ended December 31, 1997, 1998 and 1999 and the three
months ended March 31, 1999 and 2000.


     In connection with the Company's build out of the Broadband Network, the
Company has granted Global Crossing Development Co., a subsidiary of Global
Crossings Ltd. ("Global Crossing"), for a fixed advanced payment, an
indefeasible right of use ("IRU") to a portion of its broadband network capacity
(see Note 6) when the Broadband Network is completed. The Company will recognize
the revenue from the IRU ratably over the life of the IRU.

     Broadband Network -- The Broadband Network is under construction. Costs in
connection with the construction, installation and expansion of the Broadband
Network are capitalized. Depreciation will be computed using the straight-line
method over the life of the rights of way for the related network. Rights of way
agreements represent the fees paid and the net present value of fees to be paid
per signed agreements entered into for obtaining rights of way and other permits
for the Broadband Network. These capitalized agreements are being amortized over
the term of the rights of way, which range from 5 to 20 years.

     Property, Plant and Equipment Costs -- Property, plant and equipment are
recorded at cost and depreciated using the straight-line method over the
following estimated useful lives:

<TABLE>
<S>                                                       <C>
Buildings and improvements..............................  10-25 years
Operating communications equipment......................   5-10 years
Furniture, fixtures and other equipment.................   2-10 years
</TABLE>

     The operating communications equipment owned by the Company is subject to
rapid technological obsolescence. In view of these developments, the Company
decided to change the depreciable life of certain customer premises
telecommunications equipment from 10 years to 5 years effective September 30,
1999. The effect of this change in estimate totaled approximately $52.1 million
and was included in depreciation expense for 1999.

     Investments -- Investments covered under the scope of Statement of
Financial Accounting Standards ("SFAS") No. 115, Accounting for Certain
Investments in Debt and Equity Securities, are classified as "available for
sale" and are carried at fair value with any unrealized gain or loss, net of
tax, being included in accumulated other comprehensive income (loss) within
stockholders' equity. All other investments are carried at cost.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)


     The Company's investments consist of the following at December 31, 1998 and
1999 and March 31, 2000:

                                                              MARCH 31,

Investment, at cost....................  $10,708   $ 10,235   $ 10,261
Investment, at fair value ($21,527 at
  cost)................................             225,690    131,653
                                         -------   --------   --------
          Total........................  $10,708   $235,925   $141,914
                                         =======   ========   ========
</TABLE>



     The Company's cost basis investment represents a less than 1% ownership in
unaffiliated entities established for the purchase and leasing of satellite
capacity time. The fair value basis investment represents the 15.3% stake in El
Sitio's outstanding common stock, see Note 2. The Company's investment in El
Sitio's common stock is subject to equity price risk. The Company has not taken
any actions to hedge this market risk exposure.



     Deferred Financing Costs -- Debt issuance costs and transaction fees, which
are associated with the issuance of the Company's 12 1/8% Senior Guaranteed
Notes due 2003 (the "Senior Guaranteed Notes"), the 13 3/4% Senior Notes due
2005 (the "Senior Notes 2005") and the 12 3/8% Senior Notes due 2008 (the
"Senior Notes 2008") are being amortized (and charged to interest expense) over
the term of the related notes on a method which approximates the level yield
method.


     Intangible Assets -- Goodwill, representing the excess of the purchase
price over the estimated fair value of the net assets acquired of Mandic S.A.
(see Note 2) of approximately $11.7 million and other acquisitions of $0.9
million are being amortized on a straight-line basis of over a period of 15
years. In connection with the early adoption of the American Institute of
Certified Public Accountants' Statement of Position 98-5, Reporting on the Costs
of Start-Up Activities, as of January 1, 1998, the Company expensed the
unamortized license and permit costs as a cumulative effect of a change in
accounting principles. The Company reviews the carrying value of goodwill on an
ongoing basis. If such review indicates that these values may not be
recoverable, the Company's carrying value will be reduced to its estimated fair
value.

     In connection with the merger of Mandic S.A. with IMPSAT Brazil and the
subsequent sale of its retail Internet business as described in Note 2, the
Company expensed the unamortized balance of the Mandic S.A.'s goodwill of
approximately $7.4 million. Goodwill, net is included in other non-current
assets in the accompanying consolidated balance sheets.

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

     Income Taxes -- Deferred income taxes result from temporary differences in
the recognition of expenses for tax and financial reporting purposes and are
accounted for in accordance with SFAS No. 109, Accounting for Income Taxes,
which requires the liability method of computing deferred income taxes. Under
the liability method, deferred taxes are adjusted for tax rate changes as they
occur.

     Foreign Currency Translation -- The Company's subsidiaries generally use
the U.S. dollar as the functional currency. Accordingly, the financial
statements of the subsidiaries were remeasured. The effects of foreign currency
transactions and of remeasuring the financial position and results of operations
into the functional currency are included as net gain or loss on foreign
exchange, except for IMPSAT Brazil which uses the local currency as the
functional currency and its effects are included in the stockholders' equity.

     Fair Value of Financial Instruments -- The Company's financial instruments
include receivables, investment, payables, short- and long-term debt. The
Company's Senior Guaranteed Notes, Senior Notes and
                                      F-11

available for sale investment, were valued at market closing prices at December
31, 1998 and 1999. The fair value of all other financial instruments have been
determined using available market information and interest rates as of December
31, 1998 and 1999.

     At December 31, 1998 and 1999, the fair value of the Senior Guaranteed
Notes and Senior Notes was approximately $299 million and $324 million,
respectively, compared to the carrying value of $350 million. At December 31,
1999, the fair value and carrying value of the Company's investment in El
Sitio's common stock was approximately $225.7 million. The fair value of all
other financial instruments were not materially different from their carrying
value.

     Stock-Based Compensation -- SFAS No. 123, Accounting for Stock-Based
Compensation, encourages, but does not require, companies to record compensation
cost for stock-based employee and non-employee members of the Board of Directors
(the "Board") compensation plans at fair value. The Company has chosen to
continue to account for stock-based compensation to employees and non-employee
members of the Board using the intrinsic value method as prescribed by
Accounting Principles Board Opinion ("APB") No. 25, Accounting for Stock Issued
to Employees, and related interpretations. Accordingly, compensation cost for
stock options issued to employees and non-employee members of the Board are
measured as the excess, if any, of the fair value of the Company's stock at the
date of grant over the amount an employee or non-employee member of the Board
must pay for the stock.

     Stock Split -- On January 11, 2000, the Company's Board approved a .592 to
1 reverse common stock split (see Note 12). Retroactive restatement has been
made to all share amounts to reflect the stock split.

     Net Loss Per Common Share -- Basic earnings per share is computed based on
the average number of common shares outstanding and diluted earnings per share
is computed based on the average number of common and potential common shares
outstanding under the treasury stock method.

     Reclassifications -- Certain amounts in the 1997 and 1998 consolidated
financial statements have been reclassified to conform with the 1999
presentation.

     New Accounting Pronouncement-- In June 1998, the Financial Accounting
Standards Board ("FASB") issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. Among other provisions, SFAS No. 133
establishes accounting and reporting standards for derivative instruments and
for hedging activities. It also requires that an entity recognize all
derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. In June 1999, the FASB
issued SFAS No. 137, Accounting for Derivative Instruments and Hedging
Activities -- Deferral of the Effective Date of FASB Statement No. 133, an
amendment to SFAS No. 133. SFAS No. 137 deferred the effective date of adoption
of SFAS No. 133 to fiscal years beginning after June 15, 2000. Management has
not determined what effects, if any, the adoption of SFAS No. 133 will have on
the Company's consolidated financial statements.

     Nortel Networks Agreements -- On September 6, 1999, the Company executed
two turnkey agreements with Nortel Networks Corporation ("Nortel") relating to
Nortel's design and construction of segments of the Broadband Network in
Argentina and Brazil for approximately $265 million. Pursuant to these
agreements, Nortel will construct:


     - long-haul, high capacity fiber optic backbones linking major cities in
       Argentina and Brazil;

     - fiber optic and wireless radio local rings and access points within major
       cities in Argentina and Brazil; and

     - connections in Argentina and Brazil that will integrate the Company's
       networks with other providers' facilities, including submarine cable
       systems, and provide the Company with access to global telecommunications
       links.

     In addition, Nortel will provide, as part of the turnkey agreements:

     - required equipment and components;

Company to interconnect the Company's networks in Argentina and Brazil and give
the Company global international access.

     On September 22, 1999, the Company entered into a definitive agreement with
Global Crossing to construct the terrestrial portion of the Global Crossing's
South American network between Las Toninas, Argentina on the Atlantic Ocean and
Valparaiso, Chile on the Pacific Ocean (the "Trans-Andean Crossing System"). The
Company commenced construction of the Trans-Andean Crossing System in September
1999. Global Crossing will pay the Company $64 million for the Company's turnkey
construction of the Trans-Andean Crossing System, as follows:

     - construction of three ducts (the "Global Crossing Ducts") and related
       facilities over 230 route miles between Las Toninas and Buenos Aires,
       Argentina and over 290 route miles between Mendoza, Argentina and
       Valparaiso, Chile for approximately $39 million.

     - licensing to Global Crossing of one duct on our Broadband Network between
       the cities of Buenos Aires and Mendoza in Argentina for approximately $25
       million.

     During 1999, Global Crossing paid the Company $23.2 million in respect of
the ongoing construction of the Global Crossing Ducts. The Company will
accumulate all construction costs for the Global Crossing Ducts in projects
under construction and will defer all payment received from Global Crossing
until completion and deliver of the respective ducts.

     In addition to the Trans-Andean Crossing System, the Company will:


     - construct fiber optic terrestrial backhauls that will connect Global
       Crossing's submarine cable landing points in Brazil, Colombia and Peru to
       major cities in these countries


     - sell co-location space in our telehouses in Rio de Janeiro and Sao Paulo,
       Brazil; Bogota, Colombia; Lima, Peru; and Caracas, Venezuela

     The Company's telehouses will contain switching, routing and other network
co-location equipment owned by the Company or lessees of space in the
telehouses. The Company will lease space in the telehouses in Buenos Aires,
Argentina and Santiago, Chile to Global Crossing for its network operations. The
Company will also expect to enter into agreements with Global Crossing to
provide maintenance of the Global Crossing's Trans-Andean Crossing System.


     During the first quarter of 2000, the Company entered into agreements with
Global Crossing to provide Global Crossing with IRUs of up to 20 years relating
to broadband backhaul and network maintenance services in Rio de Janeiro and Sao
Paulo, Brazil. The terrestrial fiber optic backhauls will connect Global
Crossings landing points in Rio de Janeiro and Sao Paulo with its
points-of-presence to be co-located in the Company's telehouses in those cities.

     The foreign statutory tax rates range from 20% to 35% depending on the
particular country. There is no provision or benefit for U.S. income taxes, as
the Company has net operating loss carryforwards in the amount of approximately
$35.0 million, which begin to expire in the year 2010. Deferred taxes result
from temporary differences in the capitalization policies of preoperating costs,
depreciation methods and net operating loss carryforwards. The composition of
net deferred tax (liability) asset at December 31 is as follows:

     As there is no assurance that the Company will generate sufficient earnings
to utilize its available tax assets, a valuation allowance has been established
to offset deferred tax assets.

11. REDEEMABLE PREFERRED STOCK

     On March 19, 1998, the Company redeemed 25% of its outstanding common stock
previously held by STET International Netherlands NV (the "STET Shares") with
the proceeds of a substantially concurrent issuance and sale of $125 million of
the Company's Series A Convertible Preferred Stock (the "Series A Preferred
Stock"). The Series A Preferred Stock was offered and sold to Princes Gate
Investors II, L.P. ("Princes Gate") and Morgan Stanley Global Emerging Markets
Private Investment Fund, L.P. ("MSGEM"), two private equity funds that are
affiliates of Morgan Stanley Dean Witter , and to certain

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

other investors affiliated with Princes Gate and MSGEM (such investors along
with Princes Gate and MSGEM, the "Purchasers").

     The following are some of the principal features of the Series A Preferred
Stock: (a) cumulative dividends at the rate of 10% per annum, compounded
quarterly and, with certain exceptions, payable in kind; (b) mandatorily
redeemable in cash by the Company at maturity (ten years after issuance) plus
accrued and unpaid dividends; (c) callable under certain circumstances by the
Company, in whole, at 100% of the principal amount, plus accrued and unpaid
dividends; (d) convertible into common stock of the Company at any time at the
option of the Purchasers (including upon a call by the Company), at a specified
conversion rate subject to certain antidilution rights; (e) the right by
Purchasers holding a certain minimum number of outstanding Series A Preferred
Stock to appoint two directors to the Company's Board of Directors as well as to
immediately appoint half of the members of the Company's Board of Directors upon
the occurrence of certain specified events; and (f) the right by Directors
appointed by the Purchasers holding a certain minimum number of outstanding
Series A Preferred Stock, to a veto over certain major corporate actions.

     As part of the Company's initial public offering (see Note 12), the Company
redeemed approximately $32.5 million of the redeemable preferred stock and the
Purchasers converted their remaining preferred shares into 14,917,915 shares of
common stock.

12. STOCKHOLDERS' EQUITY

     Share Purchase Agreement -- On March 11, 1999, a Share Purchase Agreement
was entered into among the Company, Nevasa and Nunsgate Limited, a wholly owned
subsidiary of British Telecommunications plc ("BT"), in which the Company agreed
to issue, sell and deliver 11,934,332 newly issued shares of common stock to BT
and Nevasa agreed to sell 2,386,867 currently owned shares of common stock to BT
for $125.0 million and $25.0 million, respectively. These transactions were
consummated on April 19, 1999.

     Stock Option Plans -- In December 1998, the Company adopted the 1998 Stock
Option Plan (the "1998 Plan"), pursuant to which 4,776,016 shares of Company's
Common Stock were reserved for issuance upon exercise of options. The 1998 Plan
is designed as a means to retain and motivate key employees and directors. The
Company's compensation committee, or in the absence thereof, the Board,
administers and interprets the 1998 Plan and is authorized to grant options
thereunder to all eligible employees of the Company, including executive
officers and directors (whether or not they are employees) of the Company or
affiliated companies. Options granted under the 1998 Plan are on such terms and
at such prices as determined by the stock option committee, except that the per
share exercise price of incentive stock options cannot be less than the fair
market value of the Common Stock on the date of grant. The 1998 Plan will
terminate on December 1, 2008, unless sooner terminated by the Company's Board.

     The Company granted options for 441,650 shares at an exercise price of
$8.38 during the year ended December 31, 1998 and options for 393,340 at an
exercise price of $10.47 during the year ended December 31, 1999. These options
vest on each of the first, second and third anniversaries of the date of grant,
as to 10%, 30%, and 30%, respectively, of the granted shares. On the fourth
anniversary of the date of grant, the option vests as to the remainder of the
granted shares.

     The Company applies APB No. 25 and related interpretations in accounting
for its stock options plan to employees and non-employee members of the Board as
described in Note 3. Accordingly, no compensation expense has been recognized in
the years ended December 31, 1998 and 1999 related to this plan.

     For purposes of the following pro forma disclosures, the fair value of the
options granted in 1998 and 1999 was estimated using the minimum value method
prescribed by SFAS No. 123 for nonpublic entities with the following
assumptions: no dividend yields; no volatility; risk-free interest rate of 7.0%;
and an expected term of four years. Had compensation cost been determined based
on the fair value at the date of grant consistent with

the requirement of SFAS 123, the Company's net loss and comprehensive loss would
have increased by approximately $0.2 million and $0.3 million for the years
ended December 31, 1998 and 1999, respectively.

     On January 5, 2000, the Company's board of directors adopted the 1999 Stock
Option Plan (the "1999 Plan"), which provides for the grants to its key officers
and employees of stock options that are non- qualified for U.S. federal income
tax purposes. The terms of the 1999 Plan are otherwise identical to those of the
1998 Plan except that:

     - The total number of shares of our common stock for which options may be
       and were granted pursuant to the 1999 Plan is 355,214;

     - The exercise price is $1.69 per share of common stock; and

     - Ten percent, twenty percent, thirty percent and forty percent of the
       options granted vest on each of the fourth, fifth, sixth and seventh
       anniversaries, respectively, of the date of grant or upon a change of
       control of the Company.

     The expiration date of the 1999 Plan is January 5, 2010


     In connection with the stock options granted under the 1999 Plan, the
Company recorded approximately $5.4 million in stockholders' equity as deferred
compensation during January 2000. The deferred compensation will be amortized to
expense over the vesting period, which commences four years after the date of
grant.


     Initial Public Offering -- The Company's completed an initial public
offering ("IPO") of 11,500,000 shares of common stock on February 4, 2000. On
the same date, BT purchased 2,050,000 shares of the Company's common stock
simultaneously with this offering to maintain its approximate current ownership
share in the Company. In anticipation of the IPO, on January 11, 2000, the Board
amended and restated the articles of incorporation of the Company to change the
name of the Company to IMPSAT Fiber Networks, Inc. and authorized 300,000,000
shares of common stock, $0.01 par value, and 5,000,000 shares of "blank check"
preferred stock, $0.01 par value. In addition, the Board approved a .592 for 1
reverse common stock split (see Note 3), adopted a stockholders rights plan and
approved the issuance of 5,472,579 shares of common stock to the minority
shareholders in IMPSAT Argentina, IMPSAT Venezuela and IMPSAT Colombia in
exchange for their minority interests in those subsidiaries. The acquisition of
these minority interests will be accounted for under the purchase method.

amounting to approximately $28.5 million at December 31, 1999, and was not
obligated under any letters of credit at December 31, 1999.

     Guarantees -- The Company is a third party guarantor of up to 75% of a $6.0
million credit facility provided to IMPSAT Venezuela by a regional development
fund. At December 31, 1999, the balance outstanding on the credit facility
amounted to approximately $2.4 million.

     IMPSAT Brazil has entered into a $5.3 million term note with El Camino
Resources, which is guaranteed by the Company and IMPSAT Argentina. At December
31, 1999, the balance outstanding was approximately $4.7 million.

     Litigation -- The Company is involved in or subject to various litigation
and legal proceedings incidental to the normal conduct of its business. Whenever
justified, the Company expects to vigorously prosecute or defend such claims,
although there can be no assurance that the Company will ultimately prevail with
respect to any such matters.


     In November 1996, IMPSAT Argentina filed suit against one of its customers,
ENCOTESA, for amounts due and arising under IMPSAT Argentina's contracts with
ENCOTESA, the Argentine national postal service for $7.3 million. Although the
Company's recovery of sums related to this matter continues to be negotiated for
settlement, the Company has valued this receivable at a net receivable value of
zero.

approximately $8.9 million in foreign exchange losses during the year ended
December 31, 1999, which are reflected in net gain (loss) on foreign exchange in
the accompanying 1999 statement of operations.
