                                    INFONET

OVERVIEW

      We are a leading provider of cross-border managed data communications
services to more than 1,150 corporations worldwide, including 29% of the top
500 corporations in Business Week's 1998 Global 1000. We own and operate The
World Network, a seamless and versatile Asynchronous Transfer Mode, or ATM,
network that can be accessed from over 180 countries, making it one of the
world's largest data networks in terms of geographic coverage. Through The
World Network, we offer end-to-end seamless connectivity, an advantage over
other service providers that rely on third-party networks. We provide services
directly through our country representatives and indirectly through major
international telecommunications carriers. Our diverse client base includes
multinational corporations such as Allergan, Baan, Microsoft, Nestle, Nokia,
Pharmacia/Upjohn and Volkswagen. For the year ended March 31, 1999, we had
revenues of $303.0 million and EBITDA of $20.6 million.

      Our broad range of integrated service solutions includes Frame Relay,
remote access, intranet, multimedia, Internet and Internet Protocol, or IP,
services; consulting, design, and implementation; sale and installation of
customer premise equipment; e-mail, messaging, collaboration, Web hosting and
other value-added services.

      Our country representatives give us a significant local presence in more
than 60 countries and strong working relationships with leading local
telecommunications providers in those countries. We believe this structure also
provides us with a competitive advantage over other data service providers who
do not have comparable levels of expertise on local operating, regulatory and
market conditions. Our country representative structure emerged from our
historical relationships with major telecommunications companies, such as
Deutsche Telecom, France Telecom, Korea Telecom, Singapore Telecom and Telekom
Malaysia.

      We began operations in 1969 as a part of Computer Sciences Corporation,
or CSC. Today, our stockholders include six of the world's largest
telecommunications companies:

    .KDD--KDD Corporation (Japan);

    .KPN--KPN Telecom B.V. (The Netherlands);

    .Swisscom--Swisscom AG (Switzerland);

    .Telefonica --Telefonica International Holding B.V. (Spain);

    .Telia--Telia AB (Sweden); and

    .Telstra--Telstra Corporation Limited (Australia).

BUSINESS STRATEGY

      Our goal is to be the leading provider of global data communications
services to multinational corporations. To accomplish this objective, we will
continue to:

    .  Focus on multinational clients that require data communications
       solutions;

    .  Upgrade and expand our seamless global network;

    .  Develop innovative, value-added solutions;

    .  Strengthen our sales and customer support structure; and

    .  Provide the highest level of quality, security and reliability for our
       services.

RECENT DEVELOPMENTS

 Access to AUCS Clients

      AT&T-Unisource Communications Services N.V., which we refer to as AUCS,
was a joint venture between AT&T Corp. and Unisource N.V. providing
international voice, data, Internet and messaging services to a broad array of
multinational corporations located primarily in Europe and the United States.
Unisource is owned by three of our stockholders, KPN, Swisscom and Telia. See
"Principal and Selling Stockholders." In early 1999, AT&T elected to exit the
AUCS joint venture. As a result, AUCS sought a new partner through which it
could outsource its services beyond the European region and could provide
international networking services previously provided by AT&T. We have agreed
to provide these services.

      In our ongoing efforts to sell our services to multinational
corporations, on September 30, 1999, we entered into agreements with AUCS,
Unisource, and KPN, Swisscom and Telia. Our agreements with KPN, Swisscom and
Telia will give us access to their approximately 1,300 multinational corporate
clients currently being served by AUCS as well as additional multinational
clients to which KPN, Swisscom and Telia may provide services in the future. In
exchange for the right to market our services to their clients and $40.0
million in cash, we have issued an aggregate of 1,600 shares of our Class B
common stock to KPN, Swisscom and Telia under stock purchase agreements. Based
on publicly available information, AUCS total consolidated revenues for the
1998 calendar year were 875 million guilders, or approximately $441 million.
The multinational clients to which we will have access represented
approximately 50% of AUCS revenues over the past two years.

 Senior Secured Credit Facility

      In August 1999, we entered into a credit agreement with Merrill Lynch &
Co., as lead arranger, the Bank of Nova Scotia, as administrative agent,
Societe Generale, as documentation agent, and Merrill Lynch Capital
Corporation, Warburg Dillon Read LLC and various other banks as lenders. This
agreement provides for a $250.0 million senior secured credit facility
comprised of two term loan facilities in an aggregate principal amount of
$150.0 million which mature in June 2006 and a revolving credit facility in an
aggregate principal amount of $100.0 million that matures in August 2005. Our
ability to borrow under the facilities is subject to various conditions. See
"Description of Credit Facility."

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

      We were incorporated under the laws of the State of Delaware in March
1988 and our executive offices are located at 2160 East Grand Avenue, El
Segundo, California 90245-1022. Our telephone number is (310) 335-2600.

                                             will own approximately 100% of
                                             our Class A common stock and    %
                                             of our Class B common stock.

                                             For more information on the
                                             selling stockholders, please read
                                             the section entitled "Principal
                                             and Selling Stockholders."

 Over-allotment option...................... The selling stockholders have
                                             granted the underwriters the
                                             right to purchase up to
                                             additional shares to cover over-
                                             allotments.

 Voting rights:

       Class A common stock................. Ten votes per share.

       Class B common stock................. One vote per share.

 Other rights............................... Each class of common stock has
                                             the same dividend and liquidation
                                             rights. The Class A common stock
                                             is convertible into Class B
                                             common stock on a one-for-one
                                             basis. However, the Class A
                                             common stock cannot be sold or
                                             transferred except (1) after
                                             conversion to Class B common
                                             stock or (2) after approval by
                                             our stockholders. The Class A
                                             common stock automatically
                                             converts into Class B common
                                             stock upon the occurrence of
                                             specified events. See
                                             "Description of Capital Stock."

               SUMMARY CONSOLIDATED FINANCIAL AND OPERATING DATA

      The following table sets forth our summary consolidated financial and
operating data. You should read this information together with our consolidated
financial statements and the related notes to those statements appearing
elsewhere in this prospectus, the information under "Selected Consolidated
Financial Data" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations." The consolidated statement of operations
data for the years ended March 31, 1997, 1998 and 1999 are derived from our
audited consolidated financial statements which appear elsewhere in this
prospectus. The summary consolidated financial data as of June 30, 1999, and
for the three months ended June 30, 1998 and 1999, are derived from our
unaudited consolidated financial statements which appear elsewhere in this
prospectus. In the opinion of management, the unaudited consolidated financial
statements have been prepared on a basis consistent with our audited
consolidated financial statements and include all adjustments, which are only
normal recurring adjustments, necessary for a fair presentation of the
financial position and results of operations for the unaudited periods. The
historical results are not necessarily indicative of the operating results to
be expected in the future.

<PAGE>

- --------
(1)  Our fiscal year is the 52- or 53-week period ending on the Friday nearest
     to March 31. For simplicity of presentation, we have described the 52-week
     period ended March 28, 1997, the 53-week period ended April 3, 1998 and
     the 52-week period ended April 2, 1999 as the years ended March 31, 1997,
     1998 and 1999, and we have described the 13-week periods ended July 3,
     1998 and July 2, 1999 as the three months ended June 30, 1998 and 1999.

(2)  In our three month period ending December 31, 1999, we will record a non-
     cash compensation charge of $ , resulting from the conversion of our book
     value stock options to market value options as a result of the offering
     and a charge of $ , resulting from our stock appreciation rights, each of
     which is based upon the midpoint of the anticipated price range of this
     offering. Had the offering been completed during our three month period
     ended June 30, 1999, our net loss would have been $    and our basic and
     diluted loss per common share would have been $    .

(3)  As of March 31, 1997 and 1998 and June 30, 1998, there were no options,
     warrants or other forms of potential common stock issued by us. Our
     outstanding common stock purchase rights represent the only form of
     potential common stock as of March 31, 1999. All of these rights were
     excluded from the computation of diluted earnings per share because their
     inclusion would have had an antidilutive effect on earnings per share. Our
     outstanding common stock options represent the only form of potential
     common stock as of June 30, 1999. All of these options were excluded from
     the computation of diluted earnings per share because their inclusion
     would have been antidilutive.

(4)  EBITDA, which we calculate as income from operations before interest,
     other income (expense), provision for income taxes, depreciation,
     amortization and compensation charge for stock option plans, is a
     supplemental financial measure we use in the evaluation of our business
     and is used by many analysts in our industry. However, you should read
     EBITDA only in conjunction with our consolidated financial data summarized
     above and our consolidated financial statements and the related notes to
     those statements prepared in accordance with generally accepted accounting
     principles, which appear elsewhere in this prospectus. You should not
     construe EBITDA as an alternative to income from operations, as determined
     in accordance with generally accepted accounting principles, as an
     indicator of our operating performance or as an alternative to cash flows
     from operating activities, as determined in accordance with generally
     accepted accounting principles, as a measure of our liquidity. Our
     definition of EBITDA may not be comparable to similarly titled measures of
     other companies.

(5)  The consolidated balance sheet data presented on a pro forma as adjusted
     basis reflects: (1) the sale of         shares of our Class B common stock
     in this offering at an assumed public offering price of $        per
     share; (2) $59.9 million of outstanding borrowings under our $250.0
     million senior secured credit facility as of September 30, 1999 at a
     weighted average interest rate of 8.21%; (3) the issuance of 1,600 shares
     of our Class B common stock to KPN, Swisscom and Telia; (4) the
     termination of the repurchase right on our Class C common stock and its
     conversion into our Class B common stock upon the completion of this
     offering; and (5) the conversion of our book value stock option plan to a
     market value stock option plan.

                                  RISK FACTORS

      An investment in our Class B common stock involves risks. You should
consider carefully the following information about these risks, together with
the other information contained in this prospectus, before you decide to buy
our Class B common stock. If any of the following risks actually occur, our
business, results of operations or financial condition would likely suffer. In
that case, the market price of our Class B common stock could decline, and you
might lose all or part of the money you paid to buy our Class B common stock.

OUR ABILITY TO ACHIEVE OUR STRATEGIC OBJECTIVES WILL DEPEND IN LARGE PART UPON
THE SUCCESSFUL, TIMELY AND COST-EFFECTIVE EXPANSION OF OUR NETWORK.

      We must continue to develop and expand our network infrastructure as the
number of clients and the amount of information they wish to transport as well
as the number of services we offer increases. The expansion and development of
our network infrastructure will require substantial financial, operational and
management resources. We may not be able to expand our network adequately to
meet the demand for increased usage. If we do not expand our network rapidly
enough, additional stress may be placed on our network hardware, traffic
management and other systems and operating facilities. Our network may be
unable to service a substantial number of additional clients while maintaining
high performance and competitive data transmission speeds.

      A variety of factors, uncertainties and contingencies that are beyond our
control such as the availability of transmission capacity, price of
transmission capacity, continued deployment of our ATM-enabled network, local
regulations and availability of country representatives or other third-party
sales and support channels will affect the continued expansion of our network.
Currently, there is substantial volatility in the market price for transmission
capacity. We are investing significant capital in acquiring transmission
capacity at current fixed prices. These prices are anticipated to decline in
the future. We cannot assure you that actual expansion costs or the time
required to complete our network will not substantially exceed current
estimates. A failure to continue to expand our network may have a material
adverse effect on our ability to service our clients and to grow our business.

OUR BUSINESS IS EXPANDING RAPIDLY AND OUR BUSINESS PROSPECTS MAY SUFFER IF WE
ARE NOT ABLE TO MANAGE OUR GROWTH.

      We have experienced and are currently experiencing a period of
significant growth. This growth has placed, and our anticipated future growth
in our operations will continue to place, a significant strain on our
management, financial controls, operating and accounting systems, personnel and
other resources. We currently rely on a relatively small core management team.
As we grow, we must not only manage demands on this team but also increase its
management resources, among other things, to continue to expand, train and
manage our employee base and maintain close coordination among our technical,
accounting, finance, marketing and sales staff. We also expect the demands on
our network infrastructure and technical support resources to grow rapidly with
our expanding client base, and we may experience difficulties responding to
client demand for our services and providing technical support in accordance
with clients' expectations. We are upgrading our network infrastructure and
technical support services to address increased client demand. Our network
infrastructure, technical support and other resources may not be sufficient to
facilitate our growth. If we do not successfully manage our growth, we may be
unable to adequately support our clients' communications needs in the future.

WE RELY HEAVILY ON OUR COUNTRY REPRESENTATIVES AND OTHER THIRD-PARTY SALES
CHANNELS.

      We are and will continue to be significantly dependent on a number of
third-party relationships, including our non-consolidated country
representatives, to market and support our services. Many of our arrangements
with third-party providers are not exclusive and may be terminated at the
convenience of either party. We cannot assure you that these third parties
regard our relationship with them as important to their own

                                       7
<PAGE>

respective businesses and operations, that they will not reassess their
commitment to us at any time in the future or that they will not develop their
own competitive services.

      We may not be able to maintain or form new relationships with third
parties that supply us with clients, software or related products that are
important to our success. Accordingly, we cannot assure you that our existing
or prospective relationships will result in sustained business partnerships,
successful service offerings or the generation of significant revenues.

      We rely on our country representatives for some of the support and local
implementation necessary to deliver our services on a global basis. We also
rely on these country representatives for insights into local operating and
market conditions. The failure of these country representatives to perform
their tasks or operate their business effectively could, in turn, adversely
affect our business. In addition, we sometimes provide our country
representatives with equipment and installation services to facilitate our
market participation. We may have limited recourse, or potentially no recourse,
if they do not perform the services that we expect them to perform, and we may
not be able to recover our equipment. Our recourse may be limited because the
local laws and judicial system may not be effective in enforcing our rights.
Also, our country representatives are parties to the legal contracts with
clients. If these agreements are terminated, the clients have no obligation to
purchase our services.

      In addition, we frequently depend on our country representatives to
obtain the regulatory approvals and licenses that we need to offer our
communications services in other countries. In some cases, we cannot determine
whether they are complying with local regulatory laws or taking the steps
necessary to maintain proper licenses and permits. If any of our country
representatives lose their telecommunications licenses, whether by violating
local laws or otherwise, our business could suffer.

WE MAY NOT BE ABLE TO TRANSITION THE MULTINATIONAL CLIENTS OF KPN, SWISSCOM AND
TELIA EFFECTIVELY.

      The multinational corporate clients of KPN, Swisscom and Telia, currently
using AUCS services, have no obligation to use our services. As a result, we
cannot assure you that any significant number of these clients will continue to
use the AUCS services we will provide or transition to The World Network during
the next 12 to 18 months or at all. We cannot assure you that the clients which
do transition to our network will continue to purchase our services or, if they
continue to use our services after the transition, that they will purchase as
many or more services from us than they did from AUCS. Thus, our access to this
additional client base may not yield substantial additional revenue.

WE MAY NOT BE ABLE TO REDUCE AUCS LOSSES AND THEREFORE MAY NOT RECEIVE
MANAGEMENT FEES.

      AUCS has a history of operating losses. If we are unable to reduce the
losses of AUCS, we may not earn the incentive payments provided for in the
management agreement and may be required to rebate our entire management fee.
If this occurs, we will have expended significant amounts of management time
and operational capacity which could have been more profitably spent on other
matters.

      In addition, either party may terminate the management agreement upon 180
days' written notice, or upon 30 days' notice if agreed-upon funding
requirements of Unisource are exceeded. For additional information, please read
the section entitled "Business--AUCS Management Agreement."

DELAYS IN RECEIVING TRANSMISSION CAPACITY FROM SUPPLIERS COULD IMPAIR SERVICE
LEVELS AND OUR GROWTH.

      We lease transmission capacity from a wide range of suppliers, both to
connect client premises to our network and for other network connections. We
have from time to time experienced short-term delays in receiving the requisite
transmission capacity from suppliers. We cannot assure you that we will be able
to obtain these services in the future within the time frames required by us
and at a reasonable cost. Any failure to obtain transmission capacity on a
timely basis and at a reasonable cost in a particular jurisdiction, or any
interruption of local access services, could have an adverse effect on our
service levels and our growth.

                                       8
<PAGE>

DELAYS IN EQUIPMENT DELIVERY OR LOSS OF OUR EQUIPMENT SUPPLIERS COULD ADVERSELY
AFFECT OUR NETWORK.

      The switches and routers used in our network are provided primarily by
Nortel Networks Corp. and Cisco Systems Inc. These suppliers also sell products
to our competitors and may become competitors themselves. We may experience
delays in receiving components from our suppliers or difficulties in obtaining
their products at commercially reasonable terms. If we are required to seek
alternate sources of switches and routers, we are likely to experience delays
in obtaining the requisite equipment we need and may be required to pay higher
prices for that equipment, increasing the cost of expanding and maintaining our
network.

OUR NETWORK INFRASTRUCTURE IS VULNERABLE TO DISRUPTIONS AND SECURITY BREACHES.

      We and other network services providers may in the future experience
interruptions in service as a result of fire, natural disasters, power loss, or
the accidental or intentional actions of service users, current and former
employees and others. Although we continue to implement industry-standard
disaster recovery, security and service continuity protection measures,
including the physical protection of our plant and equipment, similar measures
taken by us or by others have been insufficient or circumvented in the past. We
cannot assure you that these measures will be sufficient or that they will not
be circumvented in the future. Unauthorized use of our network could
potentially jeopardize the security of confidential information stored in the
computer systems of or transmitted by our clients. Furthermore, addressing
security problems may result in interruptions, delays or cessation of services
to our clients. These factors may result in liability to us or our clients.

THE MARKETS WE SERVE ARE HIGHLY COMPETITIVE AND OUR COMPETITORS MAY HAVE MUCH
GREATER RESOURCES.

      Our current and potential competitors include other companies that
provide data communications services to multinational businesses, systems
integrators, national and regional Internet Service Providers, or ISPs,
wireless, cable television and satellite communications companies, software and
hardware vendors, and global, regional and local telecommunications companies.
In addition, we expect that the predicted growth of the data communications
market will attract other established companies and multinational alliances.
Further, there are established and start-up companies building global networks
and beginning to offer data communications as part of a comprehensive
communications services portfolio. Our competitors, which may operate in one or
more of these areas, include companies such as AT&T, British Telecommunications
PLC, or BT, Equant N.V., Global One, Inc. and MCI WorldCom, Inc. and new
entrants such as Qwest Communications International Inc. and Global Crossing
Ltd. Our country representatives and suppliers could also become competitors
either directly or through strategic relationships with our competitors. We
have in the past and expect in the future to encounter competition as a result
of the formation of global alliances among large telecommunications providers,
such as the newly formed joint venture between AT&T and BT.

      Several of our competitors have substantially greater financial,
technical and marketing resources, larger customer bases, greater name
recognition and more established relationships in the telecommunications
industry than we do. We cannot be sure that we will have the resources or
expertise to compete successfully in the future. Our competitors may be able
to:

    .  develop and expand their network infrastructures and service
       offerings more quickly;

    .  adapt better to new or emerging technologies and changing client
       needs;

    .  take advantage of acquisitions and other opportunities more readily;

    .  devote greater resources to the marketing and sale of their products;
       and

    .  adopt more aggressive pricing policies.

      Some of our competitors may also be able to provide clients with
additional benefits at lower overall costs. We cannot be sure that we will be
able to match cost reductions of our competitors. In addition, we believe it is
likely that there will be consolidation in our market, which could increase
price and other competition in ways that may adversely affect our business,
results of operations and financial condition.

BECAUSE WE HAVE INTERNATIONAL OPERATIONS, WE FACE ADDITIONAL RISKS RELATED TO
GLOBAL POLITICAL AND ECONOMIC CONDITIONS.

      We operate in and intend to expand further into international markets. We
cannot be sure that we will be able to obtain or build the necessary global
communications infrastructure in a cost-effective manner or compete effectively
in international markets. There are risks inherent in conducting business
internationally. These include:

    .  unexpected changes in regulatory requirements;

    .  export restrictions;

    .  tariffs and other trade barriers;

    .  challenges in staffing and managing foreign operations;

    .  differing technology standards;

    .  employment laws and practices in foreign countries;

    .  weaker intellectual property protections;

    .  political, social and economic instability;

    .  costs of services tailored to specified markets;

    .  imposition of currency exchange controls; and

    .  potentially adverse tax consequences.

      Any of these factors could adversely affect our operations. In addition,
if we are able to transition a substantial number of the AUCS multinational
clients to our system, or if we derive significant revenues from the delivery
of AUCS services, then a substantial portion of our revenues will be derived
from European clients. Therefore, a future slowdown or recession in the
European economy in particular could have a material adverse effect on our
revenues and profitability.

CURRENCY FLUCTUATIONS AND FOREIGN EXCHANGE CONTROLS COULD HAVE AN ADVERSE
EFFECT ON OUR INTERNATIONAL OPERATIONS.

      We invoice all sales of services to our country representatives and sales
channel partners in U.S. dollars. However, many of our country representatives
and sales channel partners derive their revenues and incur maintenance and
other costs in currencies other than U.S. dollars. The obligations of these
country representatives and sales channel partners whose revenues are largely
in foreign currencies will be subject to unpredictable and indeterminate
fluctuations if those currencies change relative to U.S. dollars. Furthermore,
these country representatives and sales channel partners may be or may become
subject to exchange control regulations which might restrict or prohibit the
conversion of their revenue currencies into U.S. dollars. The occurrence of any
of these factors could have a material adverse effect on our current or future
international operations.

      Our exposure to exchange rate fluctuations may increase while we
transition multinational clients of KPN, Swisscom and Telia to The World
Network because our receivables from these clients and our payables to AUCS
under the services agreement for services provided to those clients will be
denominated in different foreign currencies.

OUR BUSINESS PROSPECTS MAY SUFFER IF WE ARE NOT ABLE TO KEEP UP WITH THE RAPID
TECHNOLOGICAL DEVELOPMENTS IN OUR INDUSTRY.

      The global communications industry is subject to rapid and significant
technological changes, such as continuing developments of alternative
technologies for providing high-speed data communications. We cannot predict
the effect of technological changes on our business. We may rely in part on
third parties, including some of our competitors and potential competitors, for
the development of and access to communications and networking technologies. We
expect that new services and technologies applicable to our market will emerge.
New products and technologies may be superior and/or render obsolete the
products and technologies that we

                                       10
<PAGE>

currently use to deliver our services. Our future success will depend, in part,
on our ability to anticipate and adapt to technological changes and evolving
industry standards. We may be unable to obtain access to new technologies on
acceptable terms or at all, and we may be unable to obtain access to new
technologies and offer services in a competitive manner. Any new products and
technologies may not be compatible with our technologies and business plan. We
believe that the global communications industry should set standards to allow
for the compatibility of various products and technologies. The industry,
however, may not set standards on a timely basis or at all.

WE DEPEND ON THE SERVICES OF OUR SENIOR MANAGEMENT TEAM.

      Our future success depends to a significant extent on the continued
services of our senior management, particularly Jose A. Collazo, President and
Chairman of the Board of Directors, Akbar H. Firdosy, our Chief Financial
Officer, and other members of our executive management team. The loss of the
services of either of Mr. Collazo or Mr. Firdosy, or any other present or
future key employee, could have a material adverse effect on the management of
our business. We have a severance agreement with Mr. Collazo. We do not
maintain "key person" life insurance for any of our personnel.

COMPETITION FOR HIGHLY-SKILLED PERSONNEL IS INTENSE AND THE SUCCESS OF OUR
BUSINESS DEPENDS ON OUR ABILITY TO ATTRACT, RETAIN AND MANAGE KEY PERSONNEL.

      Our future success depends on our continuing ability to attract, retain
and motivate highly-skilled employees. As we continue to grow, we will need to
hire additional personnel in all areas. Competition for personnel throughout
the data and voice communications industries is intense. We may be unable to
attract or retain key employees or other highly qualified employees in the
future. We have from time to time in the past experienced, and we expect to
continue to experience in the future, difficulty in hiring and retaining
highly-skilled employees with appropriate qualifications. If we do not succeed
in attracting sufficient new personnel or retaining and motivating our current
personnel, our ability to provide our services could be adversely affected.

OUR EXISTING STOCKHOLDERS WILL CONTROL THE OUTCOME OF STOCKHOLDER VOTES.

      Following the offering, our existing stockholders will, in the aggregate,
beneficially own all of our Class A common stock and approximately      % of
our Class B common stock, or more than 90% of our voting power. These
stockholders will be able to exercise control over all matters requiring
approval by our stockholders, including the election of directors and approval
of significant corporate transactions. This concentration of ownership may also
have the effect of delaying or preventing a change in control of our company,
which could have a material adverse effect on our stock price.

      Immediately prior to the consummation of this offering, we expect to
enter into a stockholders agreement with all of our Class A stockholders. This
stockholders agreement will provide that each Class A stockholder holding at
least 400 shares of our Class A common stock will have the right to designate
one of our directors, and each Class A stockholder will agree to vote all of
its shares in favor of the directors designated by the other Class A
stockholders and for our president as a director. Accordingly, seven of the
nine directors on our board will be appointed by our Class A stockholders.

      In addition, our revised certificate of incorporation will contain
provisions that require the approval of 95% of the Class A stockholders to take
significant corporate actions such as a merger, consolidation or liquidation.
Based on the current ownership of our Class A common stock, we will not be able
to undertake these actions without the approval of each of our Class A
stockholders.

WE HAVE HAD OPERATING LOSSES.

      We incurred operating losses of approximately $10.4 million and $6.1
million for the years ended March 31, 1997 and 1998. We cannot assure you that
we will be able to achieve or sustain profitability from operations in the
future.

THE YEAR 2000 PROBLEM COULD SIGNIFICANTLY DISRUPT OUR OPERATIONS, CAUSING A
DECLINE IN CASH FLOW AND REVENUE AND OTHER DIFFICULTIES.

      Many currently installed computer systems and software products are
unable to distinguish between twentieth century dates and twenty-first century
dates. As a result, many companies' software and computer systems may need to
be upgraded or replaced to comply with these Year 2000 requirements. Our
business is dependent on the operations of numerous systems that could
potentially be impacted by Year 2000-related problems. As a result, we may
experience serious, unanticipated negative consequences, including material
costs caused by undetected errors in the technology used in our internal
systems.

      We believe that the greatest risk of disruption in our business exists in
less developed countries. The possible consequences of us or our key business
partners not being fully Year 2000 compliant include, among other things,
temporary network closings, delays in the delivery of services, delays in the
receipt of supplies or invoice and collection errors. Based on our assessment
of these risks and after discussions with third parties, including key vendors,
service providers, country representatives and alternate sales channel
partners, we have made an evaluation of our state of readiness, potential risks
and costs, and are preparing a contingency plan. Please read the section in
this prospectus entitled "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Impact of the Year 2000."

      We rely on several telecommunications providers to provide us with
transmission capacity. The Year 2000 compliance of telecommunications carriers
worldwide is beyond our control. There may be no possible alternate
telecommunications company available to us if a major carrier in a large
country breaks down due to Year 2000 problems. Any breakdown could prevent us
from delivering our services in that country, and possibly in other countries
where our service can be routed only through the problem country. Our inability
to deliver a significant portion of our services to our clients would have a
material adverse effect on our business, results of operations and financial
condition.

      In addition, we cannot assure you that governmental agencies, utility
companies, ISPs, third-party service providers and others outside our control
will be Year 2000 compliant. The failure of these or other entities to be Year
2000 compliant could result in a systemic failure beyond our control, such as a
prolonged Internet, telecommunications or electrical failure, which could also
prevent us from delivering our services.

OUR QUARTERLY OPERATING RESULTS MAY VARY WHICH MAY CAUSE VOLATILITY OR A
DECLINE IN THE PRICE OF OUR CLASS B COMMON STOCK.

      Our revenues and operating results may vary significantly from quarter to
quarter due to a number of factors, not all of which are in our control. These
factors include:

    .  the size and timing of significant equipment and transmission
       capacity purchases;

    .  the timing of new service offerings;

    .  changes in our pricing policies or those of our competitors;

    .  the timing and completion of our network expansion;

    .  market acceptance of data communications generally and of new and
       enhanced versions of our services in particular;

    .  the length of our contract cycles; and

    .  our success in expanding our sales force and expanding our
       distribution channels.

      In addition, a relatively large portion of our expenses are fixed in the
short-term, particularly with respect to global communications capacity,
depreciation, real estate and interest expenses and personnel, and therefore
our results of operations are particularly sensitive to fluctuations in
revenues. Due to the factors noted above and the other risks discussed in this
section, you should not rely on period-to-period comparisons of our

                                       12
<PAGE>

results of operations. Quarterly results are not necessarily meaningful and you
should not rely on them as an indication of future performance. It is possible
that in some future periods our operating results may be below the expectations
of public market analysts and investors. In this event, the price of our Class
B common stock may fall. Please see "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

WE FACE UNCERTAIN AND CHANGING REGULATORY RESTRICTIONS.

      The Federal Communications Commission, or the FCC, currently does not
regulate "enhanced services" or value-added networks that we operate in the
United States. These services are classified for regulatory purposes as
"information services" and are currently exempt from the common carrier
regulations that apply to entities providing "telecommunications services." As
a result, most of the services we provide are not currently subject to direct
regulation by the FCC or the states. Future changes in legislation or
regulation, however, could result in some aspects of our current operations
becoming subject to regulation by the FCC or a state of the United States. If
the FCC or a state seeks to regulate some segments of our activities as
"telecommunications services," we cannot predict the impact, if any, that
future regulation or regulatory changes may have on our operations.

      We currently hold common carrier authorizations to provide international
telecommunications services between the United States and other countries. We
apply for authorization as a common carrier in jurisdictions where we believe
this authorization will decrease our costs. We also hold an international
facilities license in the United Kingdom. Our licenses subject us to the
jurisdiction of the relevant regulatory body which, in turn, may require that
we make specified regulatory filings and pay attendant fees. Future regulatory,
judicial and legislative changes in countries in which we operate may impose
additional costs on us or restrict our activities. In addition, regulators or
third parties may raise material issues with regard to our compliance with
applicable regulations. Failure to comply with applicable laws or regulations
in the United States, or other countries in which we operate, could have a
material adverse effect on our operations.

THE LAW RELATING TO THE LIABILITY OF ONLINE SERVICES COMPANIES AND INTERNET
ACCESS PROVIDERS FOR DATA AND CONTENT CARRIED ON OR DISSEMINATED THROUGH THEIR
NETWORKS IS CURRENTLY UNSETTLED.

      It is possible that claims could be made against online services
companies and Internet access providers under United States and/or foreign law
for defamation, negligence, copyright or trademark infringement, or other
theories based on data or content disseminated through their networks, even if
a user independently originated this data or content. Several private lawsuits
seeking to impose liability upon online services companies and Internet access
providers have been filed in U.S. and foreign courts. While the United States
has passed laws protecting Internet access providers from liability for actions
by independent users in limited circumstances, this protection may not apply in
any particular case at issue. In addition, some countries, such as China,
regulate or restrict the transport of voice and data traffic in their
jurisdiction. The risk to us, as an Internet access provider, of potential
liability for data and content carried on or disseminated through our system
could require us to implement measures to reduce our exposure to this
liability. This may require us to expend substantial resources or to
discontinue some of our services. Our ability to monitor, censor or otherwise
restrict the types of data or content distributed through our network is
limited. Failure to comply with any applicable laws or regulations in
particular jurisdictions could result in fines, penalties or the suspension or
termination of our services in these jurisdictions. The negative attention
focused upon liability issues as a result of these lawsuits and legislative
proposals could adversely impact the growth of public Internet use. Our
professional liability insurance may not be adequate to compensate or may not
cover us at all in the event we incur liability for damages due to data and
content carried on or disseminated through our network. Any costs not covered
by insurance that are incurred as a result of this liability or alleged
liability, including any damages awarded and costs of litigation, could harm
our business and prospects.

OUR MANAGEMENT HAS BROAD DISCRETION IN SPENDING THE PROCEEDS OF THE OFFERING.

      Our management, subject to supervision by our board of directors, will
have broad discretion in spending the proceeds of the offering. Because of the
number and variability of factors that determine our use of the net proceeds of
the offering, future uses may vary from our current intentions and stockholders
may not agree with the uses we have chosen.

IF WE OR OUR EXISTING STOCKHOLDERS SELL ADDITIONAL SHARES OF OUR CLASS B COMMON
STOCK AFTER THE OFFERING, IT COULD CAUSE THE MARKET PRICE OF OUR CLASS B COMMON
STOCK TO DECLINE.

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

      Sales of our common stock are restricted by lock-up agreements that we,
our directors, officers and certain stockholders have entered into with the
underwriters. The lock-up agreements restrict us, our directors and officers
and our existing stockholders, subject to certain exceptions, from selling or
otherwise disposing of any shares for a period of 180 days after the date of
this prospectus without the prior written consent of Merrill Lynch, Pierce,
Fenner & Smith Incorporated. Merrill Lynch, Pierce, Fenner & Smith Incorporated
may, however, in its sole discretion and without notice, release all or any
portion of the shares from the restrictions in the lock-up agreements.

      After the offering, we will have       shares of Class B common stock
outstanding. Of these shares, the        shares we are offering will be freely
tradable. This leaves         shares eligible for sale in the public market as
follows:

<TABLE>
<CAPTION>
 NUMBER OF SHARES DATE
 ---------------- ----
 <C>              <S>
                  After the date of this prospectus
                  Upon the filing of a registration statement to register for
                   resale shares of Class B common stock issuable upon the ex-
                   ercise of options granted under our stock option plan
                  At various times after 90 days from the date of this prospec-
                   tus (Rule 144)
                  After 180 days from the date of this prospectus (subject, in
                   some cases, to volume limitations)
                  At various times after 180 days from the date of this pro-
                   spectus (Rule 144)
</TABLE>

      We intend to file one or more registration statements to register shares
of Class B common stock subject to outstanding stock options and Class B common
stock reserved for issuance under our stock option plan after the expiration of
the 180-day lockup. We expect the additional registration statements to become
effective immediately upon filing.

VOLATILITY OF OUR STOCK PRICE MAY EXPOSE US TO SECURITIES LITIGATION.

      The stock market has experienced significant price and volume
fluctuations, and the market prices of global communications companies have
been extremely volatile. The market price of our Class B common stock could be
affected by:

    .  quarterly variations in our operating results;

    .  technological innovations of ours or of our competitors;

    .  changes in government regulations;

    .  conditions in the international data communications and
       telecommunications industries;

    .  increased price competition;

                                       14
<PAGE>

    .  changes in earnings estimates by analysts; and

    .  changes in general economic conditions and volatility in the
       financial markets.

      In the past, following periods of volatility in the market price of a
public company's securities, securities class action litigation has often been
instituted against that company. This litigation could result in substantial
costs and a diversion of management's attention and resources.

There is no existing market for our Class B common stock.

      There has not been a public market for our Class B common stock. We
cannot predict the extent to which investor interest in our company will lead
to the development of a trading market or how liquid that market might become.
The initial public offering price for the shares will be determined by
negotiations between us and the representatives of the underwriters and may not
be indicative of prices that will prevail in the open market.

The book value of shares of Class B common stock purchased in the offering will
be immediately diluted.

      Investors who purchase Class B common stock in the offering will suffer
immediate and significant dilution in the net tangible book value per share. We
also have a large number of outstanding stock options to purchase Class B
common stock with exercise prices significantly below the estimated initial
public offering price of the Class B common stock. To the extent that these
options are exercised, there will be further dilution.

We do not intend to pay dividends on our common stock.

      We presently intend to retain future earnings, if any, to finance the
expansion of our business, rather than paying any cash dividends on our common
stock in the foreseeable future.

Our certificate of incorporation and bylaws include provisions that may
discourage a takeover attempt.

      Provisions contained in our revised certificate of incorporation, our
revised bylaws, Delaware law and our stockholders agreement could make it more
difficult for a third party to acquire us, even if doing so might be beneficial
to our stockholders. The provisions of our certificate of incorporation allow
us to issue preferred stock with rights senior to those of the Class B common
stock without any further vote or action by the stockholders. The issuance of
preferred stock also could decrease the amount of earnings and assets available
for distribution to the holders of Class B common stock or could adversely
affect the rights and powers, including voting rights, of the holders of the
Class B common stock. A provision of our certificate of incorporation,
effective upon the offering, also provides that our board of directors will be
divided into three classes, which may have the effect of delaying or preventing
a change in control or a change in our management because less than a majority
of our board of directors will be up for re-election at each annual meeting. In
addition, provisions of our bylaws and certificate of incorporation impose
various procedural and other requirements which could make it more difficult
for stockholders to effect certain corporate actions. These provisions could
limit the price that certain investors might be willing to pay in the future
for shares of our Class B common stock and may have the effect of delaying or
preventing a change in control.

                                USE OF PROCEEDS

      The net proceeds to us from the sale of the shares we are offering, after
deducting underwriting discounts and estimated offering expenses, are estimated
to be approximately $    million, assuming an initial public offering price of
$   per share. We will not receive any of the proceeds from the sale of shares
by the selling stockholders in the offering.

      We intend to use approximately $        million of the net proceeds of
the offering to develop and expand our network infrastructure, and we intend to
use the remaining net proceeds for working capital and other general corporate
purposes. Expansion of our network infrastructure includes significant
acquisitions of transmission capacity and continued deployment of the ATM-
enabled backbone.

      Our management, subject to supervision by our board of directors, will
have significant flexibility in applying the net proceeds of the offering.
Pending any use as described above, we intend to invest the net proceeds in
interest-bearing investment grade instruments. See "Risk Factors--Our
management has broad discretion in spending the proceeds of the offering."

                                DIVIDEND POLICY

      Since 1996, we have paid cash dividends of $500,000 per year on our
capital stock. However, we do not expect to pay any cash dividends for the
foreseeable future. We currently intend to retain future earnings, if any, to
finance the expansion of our business. Any determination to pay cash dividends
in the future will be at the discretion of our board of directors and will
depend upon our results of operations, financial condition, contractual
restrictions and other factors deemed relevant at that time by our board of
directors.

                                    DILUTION

      Our net tangible book value as of June 30, 1999 was $12.8 million, or
$996.49 per share of outstanding common stock. Net tangible book value per
share is equal to the amount of our total tangible assets (total assets less
intangible assets) less total liabilities, divided by the number of shares of
our common stock outstanding as of June 30, 1999. Assuming the sale of the
shares we are offering by this prospectus at an assumed initial public offering
price of $    per share and after deducting underwriting discounts and the
estimated offering expenses payable, our net tangible book value as of June 30,
1999 would have been $   , or $    per share of common stock. This represents
an immediate increase in net tangible book value of $    per share to existing
stockholders and an immediate dilution in net tangible book value of $    per
share to new investors. The following table illustrates this per share
dilution:

(1) Net of 6,781 shares of Class A common stock we hold in treasury. We paid
    $121.2 million to acquire these shares.

      The tables and calculations above assume no exercise of outstanding
options. As of June 30, 1999, there were 124 shares of our Class B common stock
reserved for issuance upon exercise of outstanding options at a weighted
average exercise price of $25,000 per share. To the extent that these options
are exercised, there will be further dilution to new investors. See

(1) Our fiscal year is the 52- or 53-week period ending on the Friday nearest
    to March 31. For simplicity of presentation, we have described the 52-week
    periods ended April 1, 1995, March 29, 1996, and March 28, 1997, the 53-
    week period ended April 3, 1998 and the 52-week period ended April 2, 1999
    as the years ended March 31, 1995, 1996, 1997, 1998 and 1999, and we have
    described the 13-week periods ended July 3, 1998 and July 2, 1999 as the
    three months ended June 30, 1998 and 1999.

(2) Reflects the acquisition of a 51% interest in Infonet Luxembourg in the
    year ended March 31, 1998.

(3) In our three month period ending December 31, 1999, we will record a non-
    cash compensation charge of $   , resulting from the conversion of our book
    value stock options to market value options as a result of the offering and
    a charge of $  , resulting from our stock appreciation rights, each of
    which is based upon the midpoint of the anticipated price range of this
    offering. Had the offering been completed during our three month period
    ended June 30, 1999, our net loss would have been $    and our basic and
    diluted loss per common share would have been $   .

(4) As of March 31, 1995, 1996, 1997 and 1998 and June 30, 1998, there were no
    options, warrants or other forms of potential common stock issued by us.
    Our outstanding common stock purchase rights represent the only form of
    potential common stock as of March 31, 1999. All of these rights were
    excluded from the computation of diluted earnings per share because their
    inclusion would have had an antidilutive effect on earnings per share. Our
    outstanding common stock options represent the only form of potential
    common stock as of June 30, 1999. All of these options were excluded from
    the computation of diluted earnings per share because their inclusion would
    have been antidilutive.

(5) EBITDA, which we calculate as income from operations before interest, other
    income (expense), provision for income taxes, depreciation, amortization
    and compensation charge for stock option plans, is a supplemental financial
    measure we use in the evaluation of our business and is used by many
    analysts in our industry. However, you should read EBITDA only in
    conjunction with our consolidated financial data summarized above and our
    consolidated financial statements and the related notes to those financial
    statements prepared in accordance with generally accepted accounting
    principles, which appear elsewhere in this prospectus. You should not
    construe EBITDA as an alternative to income from operations, as determined
    in accordance with generally accepted accounting principles, as an
    indicator of our operating performance or as an alternative to cash flows
    from operating activities, as determined in accordance with generally
    accepted accounting principles, as a measure of our liquidity. Our
    definition of EBITDA may not be comparable to similarly titled measures of
    other companies.

(6) The consolidated balance sheet data presented on a pro forma as adjusted
    basis reflects: (1) the sale of         shares of our Class B common stock
    in this offering at an assumed public offering price of $        per share;
    (2) $59.9 million of outstanding borrowings under our $250.0 million senior
    secured credit facility as of September 30, 1999 at a weighted average
    interest rate of 8.21%; (3) the issuance of 1,600 shares of our Class B

                                       21
<PAGE>

   common stock to KPN, Swisscom and Telia; (4) the termination of the
   repurchase right on our Class C common stock and its conversion into our
   Class B common stock upon the completion of this offering; and (5) the
   conversion of our book value stock option plan to a market value stock
   option plan.

(7) Includes employees of non-consolidated country representatives.

QUARTERLY REVENUE PERFORMANCE

      The following table sets forth quarterly revenue data for the year ended
March 31, 1999 and for the three months ended June 30, 1999. The information

      Our revenues vary from quarter to quarter due to a number of factors
including the timing of new client contracts, new service offerings, changes
in our pricing policies or those of our competitors and the timing and
completion of our network expansion. Quarterly results are not necessarily
meaningful and you should not rely on them as an indication of our future
performance.

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

      You should read the following discussion and analysis of our financial
condition and results of operations in conjunction with the financial
statements and the related notes to those statements appearing elsewhere in
this prospectus. This discussion contains forward-looking statements that
involve risks and uncertainties. Please see "Risk Factors--This prospectus

OVERVIEW

      We are a leading provider of cross-border managed data communications
services to more than 1,150 multinational corporations worldwide. We offer our
services to our clients directly through country representatives and indirectly
through alternate sales channels consisting of major international
telecommunications carriers and value-added resellers. We deploy a broad array
of fully managed data communications services over our reliable, secure, and
high quality global network, which we refer to as The World Network. The World
Network is a seamless and versatile ATM-enabled network that can be accessed by
our clients from over 180 countries.

      We began operations in 1969 as a part of Computer Sciences Corporation,
or CSC. In a series of transactions from 1988 to 1992, CSC sold its ownership
in Infonet to a group of telecommunications companies. From 1988 through March
31, 1999, we funded the majority of our operations, capital expenditures and
other cash requirements from internally generated funds and from two separate
stock issuances of $40.0 million each to our stockholders, one in 1995 and one
in 1999.

      Prior to October 1997, our results included the operations of Government
Systems, Inc., or GSI, a wholly owned subsidiary, and our government accounts
business, which we refer to together as Government Services. In October 1997,
we sold the assets of GSI to a third party for $21.0 million in cash and a
$5.5 million reduction in debt. For the year ended March 31, 1998, results of
operations from GSI included $32.5 million in revenues and $4.0 million in
income before taxes. In addition, we sold our government accounts to the same
third party and entered into an agreement allowing the third party to operate
as a country representative for a total of $7.0 million in cash. These
government accounts contributed $4.3 million in revenues in the year ended
March 31, 1998.

REVENUES BY REGION AND BY COUNTRY

      We provide our services throughout the world, with revenues billed and
costs incurred in more than 60 countries. The following tables set forth our
revenues by region and by country based upon the ten largest countries in terms
of revenues for the three months ended June 30, 1999. Due to the multinational
nature of our client base, the table does not reflect the country in which
services are provided, but rather is based on the jurisdiction in which we
invoice for our services.

DISTRIBUTION CHANNELS

      We offer our services through country representatives and through
alternate sales channels such as major telecommunication service providers and
value-added resellers. In the year ended March 31, 1999, country
representatives contributed 90% of our total revenues, while alternate sales
channels contributed 10% of our total revenues. The table below shows the
relative contribution to revenues from country representatives, excluding
Government Services, and alternate sales channels.

 Country Representatives

      We currently have 56 country representatives, nine consolidated and 47
non-consolidated, which together provide services in more than 60 countries.
Our consolidated country representatives are those in which we own, directly or
indirectly, greater than a 50% equity interest. Our consolidated country
representatives provide services in 14 countries and accounted for
approximately $152.4 million, or approximately 50% of our total revenues, in
the year ended March 31, 1999.

                                       24
<PAGE>

     Our service agreements with our country representatives give us the right
to recommend prices for services, set revenue targets jointly, determine
staffing jointly, appoint one of the three members of the advisory review
board, and terminate the agreement if the country representative fails to meet
the revenue targets or if we cannot agree on revenue targets for two
consecutive years. In addition, each agreement outlines the compensation and
pricing arrangements with the country representatives. Established rates and
support charges are generally the same for all country representatives
throughout the world.

     Our country representatives determine the prices they charge clients, in
accordance with our recommended prices and standard discounts, and enter into
contracts with clients to provide services using The World Network. We bill our
country representatives and recognize the full amount of revenues for all of
our services delivered to the clients. The country representatives bill us for
the sales and support services they provide, which we account for as country
representative compensation. The country representative bears the risk of
collection from the client as well as the exchange rate risk.

 Alternate Sales Channels

     Our alternate sales channel partners sell all or a portion of our suite of
services in their territories to clients that require one or more of our global
communications services that the sales channel partners cannot supply
independently. These sales channel partners include, among others, AT&T and MCI
WorldCom. Our relationships are governed by multi-year contracts, under which
we provide services to our sales channel partners who then resell our services
to clients on terms our sales channel partners determine.

COMPONENTS OF REVENUES

     Our revenues are derived from providing the following global data
communications services to our multinational clients worldwide:

    . Network Services--includes Frame Relay, remote access, intranet,
      multimedia, Internet and IP services;

    . Consulting, Integration and Provisioning Services--includes consulting,
      design, and implementation; sale and installation of customer premise
      equipment associated with the client's access to The World Network and
      use of our Network Services;

    . Applications Services--includes e-mail, messaging, collaboration, Web
      hosting and other value-added services; and

    . Other Communications Services--includes X.25 transport services,
      service access fees and other communications services.

REVENUES BY SERVICES

     We currently derive a majority of our revenues from the sale of Network
Services, specifically Frame Relay, remote access and IP services, as shown
below. We expect that Network Services will continue to constitute the largest
component of our revenue base going forward. We also anticipate that a
significant portion of our future revenue growth will continue to come from
Network Services and Consulting, Integration and Provisioning Services.

PRICING POLICIES

      The pricing for our services differs depending on the services provided,
the speed of service, geographic location and capacity utilization. In the case
of services permitting dedicated client access to the network by leased
circuit, pricing is generally dependent more on the nature and capacity of the
service provided than on actual usage. For example, the pricing for a
connection to be used for Frame Relay services generally consists of a monthly
charge for the connection and the bandwidth access provided through the
connection. Pricing for dedicated access services is therefore largely based on
access equipment and bandwidth. In the case of remote access services, actual
usage and geographic location are more relevant to the pricing determination,
as the client is generally charged based on the duration of each connected
session. Once a base service is set, additional factors are taken into account
such as charges for additional network services, breadth of the service, and
discounts for larger volume clients that are prepared to guarantee specific
revenue levels.

CLIENT CONTRACTS

      The client contracts generally include an agreed-upon price schedule that
details both fixed and variable prices for contracted services. The client
contracts generally have a term of one to three years, however, when clients
implement a number of our services, they may choose to extend the contracts for
a longer period of time. Our country representatives can easily add additional
services to existing contracts, enabling clients to increase the number of
locations through which they access our network, increase the speed of that
access, increase the sophistication of the services they use, or extend the
term for existing services.

COMPONENTS OF COSTS AND EXPENSES

 Country Representative Compensation

      Country representative compensation reflects the amounts paid to the
country representatives for the sales and support services our country
representatives provide to clients. These expenses are variable and increase as
the revenues from country representatives increase.

 Bandwidth and Related Costs

      Our bandwidth and related costs are primarily comprised of leasing and
amortization expenses associated with the leasing or purchasing of network
circuits. Currently, the majority of our network backbone infrastructure is
obtained from various providers from whom we lease bandwidth primarily under
short-term cancellable agreements. We bear these leasing expenses regardless of
whether we lease directly or indirectly through another entity that may lease
communications lines locally on our behalf. In the future, as we move towards
establishing a facilities-based network, we intend to migrate from leasing
bandwidth to purchasing bandwidth. Management believes that these purchases
will ultimately result in a lower unit cost for network infrastructure.
Bandwidth and related costs also include related equipment, maintenance and
personnel costs.

 Network Operations

      Our network operations expenses include costs associated with our network
management, operations and support activities. These costs include personnel,
occupancy, maintenance, equipment depreciation, outsourcing costs and other
network related costs.

 Selling, General and Administrative

      Selling expenses consist primarily of personnel costs and incentive
compensation related to our consolidated country representative sales force, as
well as costs related to providing centralized sales and marketing support for
our non-consolidated country representatives. Our selling expenses also include

                                       26
<PAGE>

promotion, advertising, travel and entertainment. In 1998, we began a global
advertising campaign to increase awareness of the Infonet brand name and our
service offerings. This campaign includes substantial increased spending on
advertising. General and administrative expenses consist primarily of salaries
and other compensation, and occupancy costs for executive, financial and
accounting, human resources, legal and other administrative personnel, as well
as company-wide management incentive related costs.

Future Compensation Charges Related to Stock Option and Stock Appreciation
Rights Grants

      In April 1999, we granted options to employees for the purchase of 124
shares of our Class B common stock at an exercise price of $25,000 per share
pursuant to our 1998 Stock Option Plan. The 1998 Stock Option Plan is a book
value plan which will convert to a market value plan upon the close of this
offering, creating a new measurement date for the stock options. Since the
exercise price of these options is substantially below the anticipated price to
the public in the offering, we will record a non-cash compensation charge in
our three months ended December 31, 1999. The amount of this charge is a
function of the public offering price. Based upon the midpoint of the
anticipated price range in the offering, these charges would total
approximately $      .

      During December 1998, we issued 40 stock appreciation rights, or SARs,
and during April 1999 we issued 13 SARs to employees pursuant to our SARs Plan.
The SARs vest 25% per year and are indexed to our Class B common stock at a
base price of $25,000 per share. We will record a compensation charge in each
quarter of the vesting period based upon the difference between the exercise
price and market value of our Class B common stock during the vesting period.
The total amount of this charge is a function of the price of our Class B
common stock during the vesting period. Based upon the midpoint of the
anticipated price range in the offering, these charges would total
approximately $       over the next three years. However, the aggregate amount
of these charges will differ due to fluctuations in our stock price during the
vesting period and those differences could be material.

 Three Months Ended June 30, 1999 Compared to Three Months Ended June 30, 1998

      Revenues increased $16.7 million, or 24%, from $69.0 million for the
three months ended June 30, 1998 to $85.7 million for the three months ended
June 30, 1999. This increase was primarily due to a $13.4 million increase, or
41%, growth in sales of Network Services over the period, from $32.2 million to
$45.6 million. The majority of the Network Services growth came from increased
sales of Frame Relay and remote access services. Frame Relay sales increased
$11.6 million, or 73%, from $16.0 million to $27.6 million and remote access
sales increased $3.6 million, or 72%, from $5.0 million to $8.6 million, over
the period. In addition, Consulting, Integration and Provisioning Services,
comprised primarily of our Global Connect services increased $8.5 million, or
49%, from $17.2 million to $25.7 million. Our Applications Services and our
Other Communications Services declined over the period, largely due to an
expected decline in our mature messaging product line and our X.25 transport
services as our clients are migrating to more advanced messaging applications
and non-X.25 based transport services.

      Revenues from our country representatives increased $13.2 million, or
21%, from $63.3 million for the three months ended June 30, 1998 to $76.5
million for the three months ended June 30, 1999. While we increased the number
of our country representatives from 55 to 56 over the period, the majority of
our revenue growth was derived from existing country representatives. While the
number of our clients increased only 4% from 1,114 clients as of June 30, 1998
to 1,160 as of June 30, 1999, revenues increased as clients that used mostly
lower revenue generating messaging and X.25 based transport services were
replaced by clients that purchased higher revenue yielding Network Services.
Revenues from our alternate sales channels also grew $3.5 million, or 62%, from
$5.7 million to $9.2 million. Our alternate sales channel partners resold our
suite of services to a net additional 46 clients, or 32% more clients during
the period, from 145 clients as of June 30, 1998 to 191 clients as of June 30,
1999.

      In terms of revenues billed on a regional basis, the largest portion of
our growth was in the EMEA region, which grew $10.5 million, or 30%, from $35.3
million for the three months ended June 30, 1998 to $45.8 million for the three
months ended June 30, 1999. The majority of this revenue growth was derived
from strong alternate sales channel revenue growth in The Netherlands and
strong country representative activities in the United Kingdom and Germany.
Revenues billed in the Americas increased $4.8 million, or 18%, from $26.8
million to $31.5 million over the period. Asia Pacific revenues also increased
$1.4 million, or 21%, from $6.9 million to $8.4 million.

      Country Representative Compensation increased $3.8 million, or 31%, from
$12.1 million for the three months ended June 30, 1998 to $15.9 million for the
three months ended June 30, 1999. This increase was due primarily to the
increase in the services provided by our non-consolidated country
representatives during the period. While we added one new country
representative, nearly all of the growth in these expenses came from increased
payments for services provided by our existing country representatives. These
payments are variable expenses, based on the amount and nature of services
provided by our country representatives. As such, we expect these expenses to
increase in the future as revenues generated by our country representatives
increase.

      Bandwidth and Related Costs increased $2.0 million, or 16%, from $12.6
million for the three months ended June 30, 1998 to $14.6 million for the three
months ended June 30, 1999. This increase was directly related to higher
network leasing costs associated with the increased usage on our network. The
usage growth reflects additional client port growth and increased capacity per
port. While bandwidth costs have been declining over time, clients are
demanding greater bandwidth capacity at the same price. Lease expense, the
largest component of Bandwidth and Related Costs, increased $1.7 million, or
19%, from $9.0 million to $10.7 million over the period. Amortization of
purchased capacity of $245,000 was included in the three months ended June 30,
1999, reflecting the $9.8 million purchase of new capacity in November 1998
that will be amortized over 10 years.

      Network Operations increased $1.6 million, or 13%, from $12.4 million for
the three months ended June 30, 1998 to $14.0 million for the three months
ended June 30, 1999. This increase was related to the

                                       28
<PAGE>

increased costs associated with our network management, operations and support
activities, personnel costs, depreciation and other network operations
expenses. Depreciation expense related to network equipment increased $512,000,
or 32%, from $1.5 million to $2.1 million over the period.

      Selling, General and Administrative increased $7.3 million, or 21%, from
$34.2 million for the three months ended June 30, 1998 to $41.5 million for the
three months ended June 30, 1999. The increase was due, in part, to sales
support expenses for multinational support activities which increased $3.1
million from $14.0 million for the three months ended June 30, 1998 to $17.1
million for the three months ended June 30, 1999. This increase was directly
related to revenue growth. In addition, personnel-related expenses increased by
$1.0 million from $13.7 million for the three months ended June 30, 1998 to
$14.6 million for the three months ended June 30, 1999, due to sales and
marketing efforts to grow our business. Administrative expenses increased by
$1.6 million from $3.2 million for the three months ended June 30, 1998 to $4.8
million for the three months ended June 30, 1999, primarily due to legal and
accounting fees incidental to the AUCS transactions. Depreciation expenses
increased by $582,000 from $1.4 million for the three months ended June 30,
1998 to $2.0 million for the three months ended June 30, 1999, due to the
placement of additional equipment at client premises.

      Operating Income (Loss) narrowed by $2.0 million, or 87%, from $(2.3)
million to $(300,000). This reduction in the loss was due to increased revenues
offset by a slower growth in expenses as described above.

      Other Income (Expense) decreased from income of $503,000 for the three
months ended June 30, 1998 to expense of $(176,000) for the three months ended
June 30, 1999. This decrease was due to an increase in interest expense over
the period of $455,000, or 231%, from $197,000 to $652,000. The increased
interest expense resulted from the $50.0 million bridge loan facility entered
into in May 1999. The decrease in Other Income (Expense) was also impacted by a
decline in interest income of $292,000, or 37%, from $783,000 to $491,000 over
the period.

      Provision (Credit) for Income Taxes increased $743,000, from $61,000 for
the three months ended June 30, 1998 to $804,000 for the three months ended
June 30, 1999. This increase in income taxes was due primarily to an increase
in losses during the period from a subsidiary that we were not able to
consolidate for income tax purposes.

      Net Income (Loss) decreased $643,000, or 34%, from $(1.9) million for the
three months ended June 30, 1998 to $(1.2) million for the three months ended
June 30, 1999, as a result of the factors described above.

 Year Ended March 31, 1999 Compared to Year Ended March 31, 1998

      Revenues increased $8.8 million, or 3%, from $294.2 million in the year
ended March 31, 1998 to $303.0 million in the year ended March 31, 1999.
Revenues in the year ended March 31, 1998 included $40.1 million related to
Government Services, which were sold in the year ended March 31, 1998 and thus
did not contribute to our revenues in the year ended March 31, 1999. Excluding
the contribution in 1998 from this business, our revenues would have grown
$48.8 million, or 19%, over the period from $254.2 million to $303.0 million.
This increase was primarily due to a $44.3 million increase, or 44%, in sales
of Network Services over the period, from $100.3 million to $144.6 million. The
majority of the Network Services growth came from increased sales of Frame
Relay and remote access services. Frame Relay sales increased $37.2 million, or
85%, from $43.7 million to $80.9 million and remote access sales increased
$9.8 million, or 76%, from $12.9 million to $22.7 million, over the period. In
addition, Consulting, Integration and Provisioning Services, comprised
primarily of our Global Connect services, increased $20.1 million, or 34%, from
$58.6 million to $78.8 million over the period. Our Applications Services
declined $2.4 million, or 11%, from $22.4 million to $20.1 million, and our
Other Communications Services declined $13.3 million, or 18%, from $72.8
million to $59.5 million. Our Other Communications Services decreased over the
period largely due to an expected decline in our mature messaging product line
and our X.25 transport services, as our clients are migrating to more advanced
messaging applications and non-X.25 based transport services.

                                       29
<PAGE>

      Revenues from our country representatives excluding amounts generated by
Government Services increased $33.4 million, or 14%, from $239.8 million in the
year ended March 31, 1998 to $273.2 million in the year ended March 31, 1999.
While we increased the number of our country representatives from 52 to 56 over
the period, the largest portion of our revenue growth was derived through
existing country representatives. While the number of our clients increased
only 3%, from 1,101 clients as of March 31, 1998 to 1,129 clients as of March
31, 1999, revenues increased as clients that used mostly lower revenue
generating messaging and X.25 based transport services were replaced by clients
that purchased higher revenue yielding Network Services. Revenues from our
alternate sales channels grew $15.4 million, or 107%, from $14.4 million to
$29.8 million over the period primarily due to increased revenues from
Unisource Business Network, an alternate sales channel partner operating in The
Netherlands. In total, our alternate sales channel partners resold our suite of
services to a net additional 67 clients, or 57% more clients, during the
period, from 117 clients at the year ended March 31, 1998 to 184 clients at the
year ended March 31, 1999.

      In terms of revenues billed on a regional basis, the majority of our
growth was in the EMEA region, which increased $42.1 million, or 36%, from
$116.1 million in the year ended March 31, 1998 to $158.2 million in the year
ended March 31, 1999. More than half of the growth in the EMEA region came from
strong alternate sales channel revenue growth in The Netherlands and strong
country representative activities in the United Kingdom and Germany. Revenues
billed in the Americas grew $6.9 million, or 6%, from $109.0 million to $115.9
million over the period. Revenues billed in Asia Pacific decreased by $178,000
from $29.0 million in the year ended March 31, 1998 to $28.8 million in the
year ended March 31, 1999, reflecting a slowdown in the Asian economy.

      Country Representative Compensation increased $12.6 million, or 31%, from
$41.1 million in the year ended March 31, 1998 to $53.8 million in the year
ended March 31, 1999. This increase was due primarily to the increase in the
services provided by our non-consolidated country representatives during the
period. While we added four new country representatives, nearly all of the
growth in these expenses came from increased payments for services provided by
our existing country representatives.

      Bandwidth and Related Costs increased $4.6 million, or 10%, from $48.1
million in the year ended March 31, 1998 to $52.7 million in the year ended
March 31, 1999. This increase was directly related to the increased traffic on
our network associated with higher usage of our services by our clients. The
usage growth reflects 15% client port growth and increased capacity per port.
This increase was directly related to higher network leasing costs associated
with the increased traffic on our network.

      Network Operations decreased $27.8 million or 34%, from $80.8 million in
the year ended March 31, 1998 to $53.0 million in the year ended March 31,
1999. The majority of this decrease was due to the inclusion of $24.0 million
of network operations expense related to Government Services in the year ended
March 31, 1998 and the absence of those costs in the year ended March 31, 1999
because we sold those businesses in the year ended March 31, 1998. In addition,
in the year ended March 31, 1998 we took a one-time write-off of $5.2 million
for obsolete node equipment. Excluding these factors, network operations would
have increased $1.4 million or, 3%, from $51.6 million to $53.0 million over
the period.

      Selling, General and Administrative increased $9.4 million, or 7%, from
$130.3 million in the year ended March 31, 1998 to $139.7 million in the year
ended March 31, 1999. The year ended March 31, 1998 expenses included $4.6
million in selling and administrative costs associated with GSI. Excluding this
factor, Selling, General and Administrative would have increased $14.0 million,
or 11%, from $125.7 million to $139.7 million over the period. Our sales
support expenses for multinational activities increased $7.0 million from $50.4
million in the year ended March 31, 1998 to $57.4 million in the year ended
March 31, 1999 which was directly related to revenue growth. In addition, sales
and marketing personnel related expenses increased $5.7 million for our
business while the GSI related expenses decreased $4.4 million resulting in a
net increase in these expenses of $1.3 million from $54.3 million in the year
ended March 31, 1998 to $55.6 million in the year ended March 31, 1999. The
decrease in GSI expense was due to the sale of that business and the increase
in our other business expenses was related to increased sales and marketing
efforts. Administrative expenses decreased by $2.4 million from $14.8 million
in the year ended March 31, 1998 to $12.4 million in the year

                                       30
<PAGE>

ended March 31, 1999, primarily due to changes in our management incentive
program, which was replaced by a stock incentive program to better retain key
personnel. Depreciation expenses increased by $2.3 million from $4.4 million in
the year ended March 31, 1998 to $6.7 million in the year ended March 31, 1999.
This was due primarily to increased client premise equipment not associated
with our network.

      Operating Income (Loss) increased by $9.9 million, from a loss of $(6.1)
million in the year ended March 31, 1998 to income of $3.9 million in the year
ended March 31, 1999 due to the factors described above. The year ended March
31, 1998 included $10.9 million in operating income related to Government
Services.

      Other Income (Expense) decreased from $3.6 million in the year ended
March 31, 1998 to $1.6 million in the year ended March 31, 1999. This decrease
was due to a one-time pretax gain of $3.7 million on the sale of GSI's assets
in the year ended March 31, 1998. Excluding this one-time gain, Other Income
(Expense) would have increased from $(100,000) in the year ended March 31, 1998
to $1.6 million in the year ended March 31, 1999. This increase reflects growth
in interest income of $366,000, or 24%, from $1.5 million to $1.9 million due
to higher cash balances provided by the investment of the proceeds from the
sale of Government Services. In addition, the increase reflects a slight
decrease in interest expense of $179,000, or 21%, from $868,000 to $689,000
over the period.

      Provision (Credit) for Income Taxes decreased $2.5 million, or 80%, from
$3.1 million in the year ended March 31, 1998 to $638,000 in the year ended
March 31, 1999. The unusually high tax provision in the year ended March 31,
1998, was primarily due to our inability to realize tax benefits related to
certain U.S. and foreign subsidiary losses. In the year ended March 31, 1999,
changes in circumstances allowed the U.S. tax losses from the year ended March
31, 1998 to be carried forward and included in our tax returns, resulting in a
lower than normal tax provision in the year ended March 31, 1999.

      Net Income (Loss) increased from $(5.4) million in the year ended March
31, 1998 to $4.7 million in the year ended March 31, 1999 due to the factors
described above.

Year Ended March 31, 1998 Compared to Year Ended March 31, 1997

      Revenues increased $29.6 million, or 11%, from $264.7 million in the year
ended March 31, 1997 to $294.2 million in the year ended March 31, 1998.
Revenues in the year ended March 31, 1998 included $40.1 million related to
Government Services, which were sold in the year ended March 31, 1998.
Similarly, revenues in the year ended March 31, 1997 included $45.8 million
related to Government Services. Excluding the contribution from these
businesses, our revenues would have grown $35.3 million, or 16%, over the
period from $218.9 million to $254.2 million. This increase was primarily due
to a $34.2 million increase, or 52%, growth in sales of Network Services over
the period, from $66.2 million in the year ended March 31, 1997 to $100.3
million in the year ended March 31, 1998. The majority of Network Services
growth came from increased sales of Frame Relay and remote access services.
Frame Relay sales increased $24.1 million, or 123%, from $19.6 million to $43.7
million and remote access sales increased $8.1 million, or 169% from
$4.8 million to $12.9 million, over the period. In addition, Consulting,
Integration and Provision Services, comprised primarily of our Global Connect
services increased $10.4 million, or 21%, from $48.3 million to $58.6 million
over the period. Our Applications Services revenues increased $5.8 million, or
35%, from $16.6 million to $22.4 million, and our Other Communications Services
declined $15.1 million, or 17%, from $87.9 million to $72.8 million. Our
Applications Services and Other Communications Services decreased over the
period largely due to an expected decline in our mature messaging product line
and our X.25 transport services, as our clients are migrating to more advanced
messaging applications and non-X.25 based transport services.

      Revenues from our country representatives increased $27.4 million, or
13%, from $212.4 million in the year ended March 31, 1997 to $239.8 million in
the year ended March 31, 1998. While we increased the number of our country
representatives from 51 to 52 over the period, the largest portion of our
revenue growth

                                       31
<PAGE>

was derived through existing country representatives. While the number of our
clients decreased by 4% from 1,152 clients as of March 31, 1997 to
1,101 clients as of March 31, 1998, revenue increased as clients that used
mostly lower revenue generating messaging and X.25 based transport services
were replaced by clients that purchased higher revenue yielding Network
Services. Revenues from our alternate sales channels grew $7.9 million, or
122%, from $6.5 million to $14.4 million over the period primarily due to
increased revenues from Unisource Business Network, an alternate sales channel
partner operating in The Netherlands. In total, our alternate sales channel
partners resold our suite of services to a net additional 54 customers, or 86%
more customers during the period, from 63 customers at the year ended March 31,
1997 to 117 customers at the year ended March 31, 1998.

      In terms of revenues billed on a regional basis, the majority of our
growth was in the EMEA region, which increased $25.4 million, or 28%, from
$90.7 million in the year ended March 31, 1997 to $116.1 million in the year
ended March 31, 1998 primarily due to strong alternate sales channel revenue
growth in The Netherlands, and strong country representative activities in
Germany and Sweden, partially offset by a decline in revenues in Belgium.
Revenues billed in the Americas, grew $4.2 million, or 4%, from $104.9 million
to $109.0 million over the period. Revenues billed from Asia Pacific increased
$5.7 million, or 24%, from $23.3 million in the year ended March 31, 1997 to
$29.0 million in the year ended March 31, 1998, reflecting a strong Asian
economy during the year ended March 31, 1998.

      Country Representative Compensation increased $6.0 million, or 17%, from
$35.1 million in the year ended March 31, 1997 to $41.1 million in the year
ended March 31, 1998. This increase was due primarily to the increase in the
services provided by our non-consolidated country representatives during the
period. As we added only one new country representative over the period,
effectively all of the growth in these expenses came from the growth in
payments for services provided by our existing country representatives.

      Bandwidth and Related Costs increased $5.0 million, or 11%, from $43.1
million in the year ended March 31, 1997 to $48.1 million in the year ended
March 31, 1998. This network leasing cost increase was directly related to the
increased traffic on our network associated with higher usage of our services
by our clients. The usage growth reflects 16% client port growth and increased
capacity per port.

      Network Operations decreased $300,000, from $81.1 million in the year
ended March 31, 1997 to $80.8 million in the year ended March 31, 1998. These
expenses included network operations expense related to Government Services of
$24.0 million in the year ended March 31, 1998 and $30.7 million in the year
ended March 31, 1997. In addition, in the year ended March 31, 1998 we took a
one-time write-off of $5.2 million for certain obsolete node equipment.
Excluding these factors, network operations would have increased $1.2 million,
or 2%, from $50.4 million in the year ended March 31, 1997 to $51.6 million in
the year ended March 31, 1998. This increase was related to the increased costs
associated with our network management, operations and support activities,
including depreciation and personnel costs.

      Selling, General and Administrative increased $14.5 million, or 13%, from
$115.7 million in the year ended March 31, 1997 to $130.3 million in the year
ended March 31, 1998. These expenses included selling and administrative costs
associated with GSI of $6.8 million in the year ended March 31, 1997 and $4.6
million in the year ended March 31, 1998. Excluding GSI, these expenses would
have increased $16.8 million, or 15%, from $108.9 million to $125.7 million
over the period. Our sales support expenses for multinational support
activities increased $8.3 million from $42.1 million in the year ended March
31, 1997 to $50.4 million in the year ended March 31, 1998. The increases were
directly related to revenue growth. Sales and marketing personnel and related
expenses increased $2.1 million for our business while expenses related to GSI
decreased $2.2 million, resulting in a net decrease of these expenses of
$100,000 from $54.4 million in the year ended March 31, 1997 to $54.3 million
in the year ended March 31, 1998. The decrease in GSI expense was due to a
change in business strategy and the increase in our other business expenses was
related to increased sales and marketing efforts to grow the business.
Administrative expenses increased $3.4 million from $11.4 million in the year
ended March 31, 1997 to $14.8 million in the year ended March 31, 1998, due to
changes in our management incentive program. Depreciation expenses decreased by
$400,000 from $4.8 million in the year

                                       32
<PAGE>

ended March 31, 1997 to $4.4 million in the year ended March 31, 1998. This was
due primarily to increased customer premise equipment, offset by a one time
adjustment in the year ended March 31, 1997.

      Operating Income (Loss) narrowed by $4.3 million, or 42%, from a loss of
$(10.4) million in the year ended March 31, 1997 to a loss of $(6.1) million in
the year ended March 31, 1998 due to the factors described above.

      Other Income (Expense) increased from $2.7 million in the year ended
March 31, 1997 to $3.6 million in the year ended March 31, 1998. This reflects
growth in interest income of $501,000, or 49%, from $1.0 million to $1.5
million due to higher cash balances provided by the investment of the proceeds
from the sale of Government Services. In addition, Other, net increased by
$378,000 for the year ended March 31, 1998 primarily related to lower foreign
exchange losses during the period. The year ended March 31, 1998 included a
one-time pretax gain of $3.7 million related to the sale of GSI's assets.
Similarly, the year ended March 31, 1997 included a one-time pretax gain of
$3.7 million related to the sale of an Internet business in Belgium.

      Provision (Credit) for Income Taxes increased $3.3 million, from
$(175,000) in the year ended March 31, 1997 to $3.1 million in the year ended
March 31, 1998. The unusually high tax provision in the year ended March 31,
1998, was primarily due to our inability to realize tax benefits related to net
operating losses of U.S. and foreign subsidiaries.

      Net Income (Loss) narrowed from $(7.5) million in the year ended March
31, 1997 to $(5.4) million in the year ended March 31, 1998 due to the factors
described above.

Liquidity and Capital Resources

      Net cash provided by operating activities was $2.1 million in each of the
three month periods ended June 30, 1998 and 1999. Net cash used in investing
activities for the three months ended June 30, 1999 was $24.9 million compared
to $1.0 million for the three months ended June 30, 1998. The increased cash
used in investing activities in this period primarily resulted from increased
spending of $23.7 million for property, equipment and communications lines. Net
cash provided by financing activities for the three months ended June 30, 1999
was $49.2 million compared to net cash used in financing activities of $412,000
for the three months ended June 30, 1998. This increased cash provided by
financing activities primarily resulted from borrowings under a bridge loan in
the amount of $50.0 million.

      Net cash provided by operating activities during the year ended March 31,
1999 was $13.6 million compared to $14.4 million during the year ended March
31, 1998. The decrease in net cash provided by operating activities in 1999
resulted primarily from a $7.4 million decrease in depreciation and
amortization expense, a $6.7 million increase in deferred income tax assets and
an $11.0 million increase in accounts receivable which were substantially
offset by an increase in net income of $10.1 million and the absence of the
$10.7 million gain from the sale of Government Services in 1999. The decrease
in depreciation and amortization expense was primarily the result of the write-
off of obsolete equipment and the sale of GSI's assets in 1998. We expect
depreciation and amortization expense to increase in the future. Net cash used
in investing activities for 1999 was $22.4 million compared to $6.9 million for
1998. The increase in cash used in investing activities in 1999 primarily
reflects the sale in 1998 of GSI for net proceeds of $22.0 million. Net cash
provided by financing activities for 1999 was $5.8 million compared to net cash
used in financing activities in 1998 of $14.4 million, resulting primarily from
the issuance of $16.0 million of long-term obligations in 1999.

      Net cash provided by operating activities during the year ended March 31,
1998 was $14.4 million compared to $1.6 million in the year ended March 31,
1997. The increase in net cash provided by operating activities in 1998 was
primarily attributable to a decrease in net loss of $2.0 million, a $4.1
million increase in depreciation and amortization and increases in most
operating liabilities, partially offset by the gain of $10.7 million from the
sale of Government Services in 1998. Net cash used in investing activities for
1998 was

                                       33
<PAGE>

$6.9 million compared to $5.0 million for 1997. The increase in cash used for
investing activities during this period primarily resulted from net increased
purchases of short-term investments and other securities of $18.8 million and
increased purchases of property, equipment and communication lines of $6.5
million, partially offset by net proceeds of $22.0 million from the sale of
Government Services. Net cash used in financing activities for 1998 was $14.4
million compared to net cash provided by financing activities of approximately
$13.0 million for the year ended March 31, 1997. The increase in net cash used
in financing activities in the year ended March 31, 1998 primarily reflects the
repayment of $12.0 million of net long-term obligations issued in 1997 and the
absence of $3.3 million of net cash provided by the sale and repurchase of
common stock in 1997.

      As of June 30, 1999, we had $34.7 million of cash and cash equivalents
and working capital of $40.7 million.

      In May 1999, we entered into a $50.0 million bridge loan facility with
Merrill Lynch Capital Corporation. This facility provided for an interest rate
of LIBOR plus 2.5%. In August 1999, we entered into a senior secured credit
facility with a group of lenders. This $250.0 million senior secured credit
facility consists of a seven year $100.0 million Delayed Draw Term Loan, a
seven year $50.0 million Tranche B Term Loan, and a six year $100.0 million
Revolving Credit Facility. The Tranche B Term Loan was fully funded at closing
and was used to pay down in full all amounts outstanding on August 20, 1999
under the bridge loan and a $9.5 million note payable. The Delayed Draw Term
Loan was partially funded in the amount of $10.0 million at closing.

      Availability under the senior secured credit facility is determined by a
number of factors including financial covenants, financial ratios and other
conditions. The term loan facilities mature in June 2006 and the revolving
credit facility matures in August 2005. Amortization and reduced availability
begins September 30, 1999 pursuant to a schedule. Interest on the loans is
payable, at a variable rate based on, at our option, either the base rate or
the eurodollar rate, in each case, plus a margin. The margin for term loans
(and, prior to February 20, 2000, for revolving credit loans) is fixed by
facility and by type of loan at the rates specified in the credit agreement and
ranges from 1.50% to 2.75%. From and after February 20, 2000, the margin for
revolving credit loans varies depending on the ratio of our total indebtedness
to consolidated EBITDA and ranges from 0.50% to 2.50%. Furthermore, we are
required by February 2000 to enter into hedge agreements that fix the interest
rate on at least 50% of the outstanding term loans for a period satisfactory to
our lenders. The senior secured credit facility is secured by substantially all
of our assets and a pledge of the stock of our direct and indirect
subsidiaries, requires us to maintain certain financial covenants and places
restrictions on, among other things, the payment of dividends, the incurrence
of debt and liens, the disposition of assets, transactions with affiliates and
certain investments. Deferred financing fees related to obtaining this senior
secured credit facility and the bridge loan were approximately $4.9 million.

      In June 1999, we authorized, and have subsequently issued, 1,600 shares
of our Class B common stock to KPN, Swisscom and Telia in exchange for access
to their multinational clients and $40.0 million in cash. See "Business--Access
to Multinational Corporate Clients of KPN, Swisscom and Telia." We expect to
use the funds from this issuance for continued upgrade and expansion of our
network and for general corporate purposes.

      Our principal capital expenditure requirements involve the upgrade and
expansion of The World Network through the purchase or lease of transmission
capacity and the purchase of network related equipment as well as computer
equipment, furniture and fixtures. We have funded these expenditures to date
primarily through cash from operations, borrowings under our bridge loan
facility and operating and capitalized leases. Our capital expenditures for the
year ended March 31, 1999 were approximately $11.7 million for network related
equipment, approximately $9.8 million for the purchase of transmission capacity
and approximately $5.5 million for other capital expenditures. As of March 31,
1999, we had capital lease commitments totaling approximately $8.1 million
payable in various years through 2004.


                                       34
<PAGE>

      In connection with the deployment of our ATM-enabled backbone, we
estimate that we will make at least $100.0 million of capital expenditures
during the year ending March 31, 2000. We expect our capital expenditures for
the year ending March 31, 2000 to include $18.0 million for the purchase of an
indefeasible right of use of capacity in a fiberoptic submarine cable system.
In addition, we will have the option for 90 days from the date of occupancy to
purchase our new headquarters facility for approximately $33.0 million. If we
exercise this option, we may finance this purchase with proceeds of the
offering, cash from operations or a mortgage loan from a commercial lender. We
expect that our capital expenditures will be the same or higher in the year
ending March 31, 2001. These expenditures will include payments of
approximately $27.0 million for the purchase of additional submarine cable
capacity. We expect to use cash from operations together with the proceeds of
the offering and availability under the senior secured credit facility to fund
these capital expenditures. The exact amount of future capital expenditures
will depend on a number of factors, including availability under our senior
secured credit facility, our ability to negotiate contracts to purchase
transmission capacity at favorable prices and the demands of our multinational
clients. If we have exhausted the net proceeds of this offering and borrowings
under the senior secured credit facility are not available, we may be required
to seek additional debt or equity financing. We cannot assure you that any
financing will be available on commercially reasonable terms or at all, or that
any additional debt financing would be permitted by the terms of our existing
indebtedness.

      Our ability to make scheduled payments of principal of, or to pay
interest on, our debt obligations, and our ability to refinance any debt
obligations, or to fund planned capital expenditures, will depend on our future
performance, which, to a certain extent, is subject to general economic,
financial, competitive, regulatory and other factors that are beyond our
control. Our business strategy contemplates substantial capital expenditures in
connection with the upgrade and expansion of The World Network. We believe that
cash flow from operations and the proceeds of the offering and available
borrowings under our senior secured credit facility will be sufficient to fund
our anticipated capital expenditures through the year ending March 31, 2002.

INFLATION

      The impact of inflation on our operations has not been significant to
date. Over the past two years, rising prices for some of our supplies have been
offset by decreasing prices for other services. In particular, our per unit
costs for leased lines and circuits has generally decreased over this period.
However, we cannot assure you that per unit costs for leased lines and circuits
will continue to decline or that a high rate of inflation in the future will
not adversely affect our operating results.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      We are exposed to market risks, which arise during the normal course of
business from changes in foreign exchange rates and interest rates. A
discussion of our primary market risks associated with our foreign currency
transactions, short-term investments, and long-term debt exposure is presented
below.

 Foreign Exchange Risk

      We conduct our operations in more than 60 countries around the world in a
number of different currencies. There is exposure to future earnings when
foreign exchange rates change and certain receivables, payables and
intercompany transactions are denominated in foreign currencies. We monitor our
exposure to foreign currencies through our regular operating activities and
have not historically used derivatives to hedge foreign exchange risk.

      We bill our country representatives in U.S. dollars and our prices are in
U.S. dollars. However, many of our country representatives derive their
revenues and incur costs in currencies other than U.S. dollars. To the extent
that the local currency used by the country representative fluctuates against
the U.S. dollar, the obligations of the country representative may increase or
decrease significantly and lead to foreign exchange losses or gains. We assume
the exchange rate risk for our consolidated country representatives, although
our

                                       35
<PAGE>

non-consolidated country representatives assume the exchange rate risk under
our country representative structure. Our exposure to exchange rate
fluctuations may increase while we transition multinational clients of KPN,
Swisscom and Telia to The World Network because our receivables from these
clients and our payables to AUCS under the services agreement for services
provided to those clients will be denominated in different foreign currencies.

      As of March 31, 1999 we were primarily exposed to the following
currencies: the Canadian dollar, the British pound, the Belgian franc, the
French franc, and the Spanish peseta. Based upon a hypothetical ten-percent
strengthening of the U.S. dollar across all currencies, the potential losses in
future earnings due to foreign currency exposures would have been approximately
$513,000 as of that date.

 Interest Rate Risk

      We currently maintain an investment portfolio of high quality marketable
securities. According to our investment policy, we may invest in taxable
instruments including U.S. Treasury bills, obligations issued by government
agencies, certificates of deposit, commercial paper, master notes, corporate
notes and asset-backed securities. In addition, the policy establishes limits
on credit quality, maturity, issuer and type of instrument. All securities are
classified as available for sale, and recorded in the balance sheet at fair
value. Fluctuations in fair value attributable to changes in interest rates are
reported as a separate component of stockholders' equity. We do not use
derivative instruments to hedge our investment portfolio.

      All highly liquid investments with a maturity of three months or less at
the date of purchase are considered to be cash equivalents. The remaining
short-term investments have maturities that range between three and 12 months.

      The carrying amount, principal maturity and estimated fair value of our
investment portfolio and long-term debt exposure are as follows:

</TABLE>

      We have not historically used derivatives to hedge our interest rate
risk. However, under the terms of our senior secured credit facility entered
into on August 17, 1999, we will be required to enter into hedge agreements to
provide that at least 50% of the outstanding term loans are subject to fixed
interest rates.

Impact of the Year 2000

      Many currently installed computer systems and software products are coded
to accept or recognize only two digit entries in the date code field. These
systems may recognize a date using "00" as the year 1900 rather than the year
2000. As a result, computer systems and/or software that many companies and
governmental agencies use may need to be upgraded to comply with Year 2000
requirements or risk system failure or miscalculations causing disruptions of
normal business activities.

                                       36
<PAGE>

      In August 1996, we began working on our Year 2000 readiness project. As
part of the Year 2000 project, we have reviewed the Year 2000 readiness of all
of our systems, software and equipment, including our messaging systems,
billing systems and network services. Following our review, we conducted
simulation and integration tests of our systems. This testing was for the most
part completed by December 1998.

      In our review and testing process we identified several critical and non-
critical systems with Year 2000 problems. To date, most of these systems have
been removed, replaced by compliant systems or transferred to Year 2000
compliant environments, except for one system that requires the cooperation of
multiple third parties in order to migrate to a Year 2000 compliant
environment. We expect this migration to be completed by October 31, 1999.

      We have requested that all of our key vendors, service providers and
sales channels provide us with statements of their Year 2000 readiness.
Wherever possible, our final determination as to whether these entities are
Year 2000 compliant has been based on our testing process, rather than their
responses to our requests. We have received responses from over two-thirds of
our key vendors, service providers and sales channels indicating that they are
compliant and are following up with those who have not yet responded.

      In order to minimize the risk of operational problems due to the Year
2000 date change, we will avoid making changes to our network, services,
products and processes from the period October 1, 1999 to March 31, 2000. We
will, however, continue to support existing and new clients and make client
modifications, although we will not make structural changes such as node
migrations or formatting network modifications during this period.

      To date, almost all of the work associated with our Year 2000 project has
been completed. As of June 30, 1999, we had spent approximately $1.0 million on
our Year 2000 project and do not expect to incur significant additional costs.
Additionally, we have incurred capital expenditures of approximately $2.2
million in upgrading our network to satisfy Year 2000 requirements.

      We believe that the greatest risk of disruption in our businesses exists
in less developed countries. The possible consequences of us or our key
business partners not being fully Year 2000 compliant include, among other
things, temporary network closings, delays in the delivery of services, delays
in the receipt of supplies or invoices and collection errors. Based on our
assessment of these risks and after discussions with third parties, including
key vendors, service providers, country representatives and alternate sales
channel partners, we have made an evaluation of our state of readiness,
potential risks and costs, and are preparing a contingency plan. This
contingency plan is intended to prepare us for failures by these parties and
other business partners.

      Our business and results of operations could be materially adversely
affected by a temporary inability to conduct our business in the ordinary
course for a period of time after January 1, 2000. We believe, however, that
our Year 2000 readiness program, including the contingency planning discussed
above, should significantly reduce the extent of any disruption. See "Risk
Factors--The Year 2000 problem could significantly disrupt our operations,
causing a decline in cash flow and revenue and other difficulties."

RECENTLY ADOPTED ACCOUNTING STANDARDS

      During 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which establishes new standards for
reporting derivative and hedging information. The standard is effective for
periods beginning after June 15, 2000 and will be adopted by us by April 1,
2001. We have not assessed the impact that the adoption of this standard will
have on our consolidated financial position or results of operations.

      The information provided in "Industry" regarding growth in the
communications market was obtained from Data Communications magazine. Although
we believe that this source is reliable, we cannot assure you that these
projections will prove to be correct. See "Risk Factors."

MARKET OPPORTUNITY

      With developments in network technology, advances in communications
service offerings and the globalization of business, multinational corporations
are increasingly demanding integrated solutions for their mission-critical
global communications needs. In addition, the rapid expansion and adoption of
the public Internet is creating additional opportunities for corporations to
interact with a large number of geographically distributed offices, employees,
customers, suppliers and partners. However, the public Internet was not
designed with the reliability, consistency, response time and security required
for mission-critical applications. As a result, multinational corporations rely
on service providers to enhance the quality, reliability and security of their
data communications and to provide global access equivalent to the public
Internet. These corporations require integrated solutions that span multiple
countries, have guaranteed network availability, can deliver continuous
increases in speed and capacity and provide local service and support. The
demand for these managed data services has dramatically increased the size and
growth rate of the communications marketplace.

      The size of the global communications market reached approximately $800
billion in 1998, according to the International Telecommunications Union. The
market for data communications is one of the fastest growing segments of this
market. According to Data Communications, a leading magazine covering
enterprise networking, the global data communications services market, which
includes Frame Relay, ATM, Intranet services, commercial Internet services and
Web hosting, was approximately $22 billion in 1998, or 2.8% of the global
communications market and had a compound annual growth rate of 55% from 1996 to
1998. Within this market, we focus on cross-border managed data communications
services for multinational corporations.

 Industry Drivers

      We believe that there is an attractive opportunity for marketing managed
data communications services to multinational corporations which results from
the following factors:

    .  globalization of business and increased need for connecting
       international locations;

    .  rapid expansion of Internet-based applications;

    .  rising importance of data communications as a service critical to a
       corporation's success; and

    .  increased outsourcing of corporate data communications.

      Globalization of business and increased need for connecting international
locations. Over the past several decades, corporations have significantly
increased the international scope of their businesses. These corporations have
opened and made direct investments in branch offices, factories, and other
local representative facilities around the globe. It is critical for these
corporations to share information accurately and expediently between their
geographically dispersed locations, as well as with travelling and
telecommuting employees. New technologies and advanced remote access
alternatives are enabling these geographically dispersed employees to connect
to corporate and public networks at greater speeds, as well as from more varied
locations.

      Rapid expansion of Internet-based applications. Internet-based
applications are rapidly expanding as an important medium for global
communications and e-commerce with the potential to connect a large number of
geographically dispersed offices, employees, customers, suppliers and partners.
Internet-based applications

                                       38
<PAGE>

have emerged as a strategic component of business, and investment in Internet
services has increased dramatically. The public Internet's lack of reliability
and security for mission-critical data communications, however, has forced many
corporations to seek assistance from service providers and data network
companies to enhance the quality of their Internet communications or to design
and implement high performance private networks.

      Rising importance of data communications as a service critical to a
corporation's success. An increasing number of businesses are investing in data
networks to achieve higher levels of productivity and lower operating expenses.
Increasingly, corporate intranets, public Internet Web sites, extranets and
other managed data networks are creating competitive advantages for companies
that use them to foster internal communications, e-commerce, source supplies,
recruit new employees, communicate with customers, penetrate new market
segments and collect market information. Corporations are demanding that their
networks deliver data quickly, consistently and globally and that these
networks can be upgraded as the complexity of the applications grows and
technologies change. Corporations also require networks that operate 24-hours a
day, seven days a week, and offer application support and a broad range of
functions, such as security, remote access and reliability.

      Increased outsourcing of corporate data communications. Corporations are
focusing their resources on their core competencies. Investing in resources and
personnel required to maintain in-house private corporate networks is costly
and difficult, especially given the shortage of technical talent and risk of
technological change. The ongoing expansion of multinational businesses and
developments in technology, have made it difficult for in-house solutions to
keep pace with corporate needs. Therefore, corporations have sought third
parties to provide managed data communications services. Given the costs and
difficulties involved in implementing international network solutions, we
believe that multinational corporations are even more likely to outsource their
cross-border data communications needs.

TECHNOLOGY OVERVIEW

      The evolution of computing and data network services has had a major
impact on the ways companies function. Most multinational corporations now
depend upon the efficient transmission of information through effective
communications networks. At particular sites, organizations employ localized
data networks known as local area networks, or LANs, to connect personal
computers. These LANs can be used to promote collaborative work practices
through data and directory sharing, facilitate communications through e-mail
and voice messaging, and simplify administrative procedures through services
such as direct facsimile transmission from a desktop computer. When LANs are
connected through a larger network, commonly referred to as a wide area
network, or WAN, an organization is able to replicate the services that can be
provided by a LAN seamlessly throughout the organization's various sites,
enabling personnel in diverse locations to share information.

      A WAN which is designed to connect to and provide information from
diverse locations within a corporate organization is often referred to as an
intranet. An intranet operates like the public Internet but with more
consistent performance and better security. Intranets can also be used to
transmit information to and receive information from outside an organization,
enabling a company to engage in e-commerce. When a WAN or intranet is able to
transmit and receive information from outside an organization via the public
Internet, it is often referred to as an extranet.

      Data protocols enable computers to exchange information by using a
commonly understood language and set of rules. Protocols are critical in data
communications because they dictate the speed and flexibility with which data
can be exchanged between computers. The following are the most commonly used
protocols:

    .  X.25 is a protocol that allows dial-up or permanent access to a
       network from the user's premises at low to medium speeds from 9.6 to
       64 kilobits per second, or Kbps. X.25 is suitable for most lower
       performance applications and for users in developing countries that
       lack the communications infrastructure to deliver high speed
       services;

                                       39
<PAGE>

    .  Frame Relay is a wide area protocol designed for transporting data at
       higher speeds of up to 2 megabits per second, or Mbps. Frame Relay is
       particularly suited for users who transmit high volumes of data. As
       such, Frame Relay is a cost-effective means of connecting
       geographically dispersed LANs;

    .  ATM is a high speed protocol that is capable of very high
       transmission rates, primarily 45 Mbps or greater. ATM can be deployed
       both as a protocol to transport data within core networks and as a
       technology that enables high volume users to access a network. Both
       LANs and WANs can use ATM to support broadband services such as
       voice, video and data services; and

    .  Internet Protocol, or IP, is the protocol used for the Internet and
       on many LANs and WANs that enables efficient communications across
       data networks regardless of the hardware, software and protocols
       used. IP permits WANs and LANs to operate seamlessly with one another
       and permits varied networking and computer platforms to exchange
       information. IP standards can be used to create intranets that link
       IP-based corporate networks and to create extranets to connect
       corporate networks to the public Internet.

                                    BUSINESS

OVERVIEW

      We are a leading provider of cross-border managed data communications
services to more than 1,150 corporations worldwide, including 29% of the top
500 corporations in Business Week's 1998 Global 1000. Our network, which we
refer to as The World Network, can be accessed from over 180 countries, making
it one of the world's largest data networks in terms of geographic coverage. We
own and operate our network on an end-to-end basis giving us seamless
connectivity, an advantage over other service providers that rely on third-
party networks. We provide services directly through our country
representatives and indirectly through major international telecommunications
carriers, such as AT&T and MCI WorldCom, and value-added resellers. Our country
representatives give us a significant local presence in more than 60 countries
and strong working relationships with leading local telecommunications
providers in these countries. Our diverse client base includes multinational
corporations such as Allergan, Baan, Microsoft, Nestle, Nokia, Pharmacia/Upjohn
and Volkswagen.

      We offer a broad range of integrated service solutions to our clients,
such as:

    .  Network Services--includes Frame Relay, remote access, intranet,
       multimedia, Internet and IP services;

    .  Consulting, Integration and Provisioning Services--includes
       consulting, design, and implementation; sale and installation of
       customer premise equipment associated with the client's access to The
       World Network and use of our Network Services;

    .  Applications Services--includes e-mail, messaging, collaboration, Web
       hosting and other value-added services; and

    .  Other Communications Services--includes X.25 transport services,
       service access fees and other communications services.

      We take a consultative, applications-oriented approach to identifying
client needs and developing customized solutions. In addition, we offer a
consolidated billing, management and support system which provides a complete
solution for all the external and internal data communications services our
multinational clients require. Our approach is to integrate our full range of
services with the data communications and network operations of our clients. We
believe our ability to provide a comprehensive solution to our clients gives us
a key competitive advantage because our solutions are costly to develop and
difficult to replicate.

      We own and operate The World Network, a seamless and versatile ATM-
enabled network that provides the delivery platform for our integrated,
enterprise-wide communications solutions. The World Network has approximately
11,142 ports comprised of over 6,000 IP, Frame Relay and X.25 access and
customer premise devices which are connected by over 950,000 route-kilometers
of data transmission circuits, most of which are over fiberoptic routes. This
global private network enables our clients to deploy and manage applications
effectively by combining reliability, security, high performance and a broad
range of functions using a variety of network protocols.

      Our global sales and support structure, based on partnerships with local
telecommunications and other service providers, gives us a strong presence in
each of our markets. We believe this structure also provides us with a
competitive advantage over other data service providers who do not have
comparable levels of expertise as to local operating, regulatory and market
conditions. Our country representative structure emerged from our historical
relationships with major telecommunications companies, such as Deutsche
Telecom, France Telecom, Korea Telecom, Singapore Telecom and Telekom Malaysia.

                                       41

      We began operations in 1969 as a part of Computer Sciences Corporation,
or CSC. In a series of transactions from 1988 to 1992, CSC sold its ownership
in Infonet to a group of telecommunications companies. Our current stockholders
include six of the world's largest telecommunications companies:

      .  KDD--KDD Corporation (Japan);

      .  KPN--KPN Telecom B.V. (The Netherlands);

      .  Swisscom--Swisscom AG (Switzerland);

      .  Telefonica--Telefonica International Holding B.V. (Spain);

      .  Telia--Telia AB (Sweden); and

      .  Telstra--Telstra Corporation Limited (Australia).

BUSINESS STRATEGY

      Our goal is to be the leading provider of global data communications
services to multinational corporations. We will continue to:

 Focus on multinational clients that require data communications solutions

      We will continue to focus on multinational corporations with cross-border
managed data communications needs. We believe that the rapid pace of
technological change, and the resultant complexity and cost of network
communications services, are causing large multinational corporations to
outsource their data communications services to focus on their core
competencies. Our flexible network architecture, local presence in more than 60
countries and consultative sales approach allow us to tailor our data
communications solutions to meet our clients' needs. Given the global reach of
our network, our local support services and our reputation for reliable and
innovative services, we believe we can further penetrate the market for global
data services. Between 1996 and 1998, we increased our penetration of the top
500 corporations in Business Week's Global 1000 from 21% to 29%. As part of
this strategy, we have launched a global branding program to increase awareness
of our services and the Infonet brand.

 Upgrade and expand our seamless global network

      We intend to invest significant capital resources to upgrade and expand
further The World Network to maintain our competitive advantage. Currently, the
majority of our backbone is comprised of circuits leased on a short-term basis.
We are in the process of making significant purchases of transmission capacity
on major terrestrial and undersea routes. We believe that these investments
will enable us to exploit economies of scale associated with high volume
transmission capacity and better meet our clients' requirements for higher
speed connections. Also, as part of this strategy, we are currently expanding
the deployment of ATM backbone switches that will connect our core network
nodes around the world. We believe this ATM-enabled network will provide
greater capacity and improved functionality. We expect to use our ATM-enabled
network as a platform to offer a broader range of value-added services that
combine voice, video and data.

 Develop innovative, value-added solutions

      We are continually developing new solutions to meet our clients' rapidly
changing needs due to technological advances and the globalization of their
businesses. For example, we were the first to offer multiple levels of Frame
Relay service to our clients, providing them the flexibility to manage
standard, as well as mission-critical operations effectively through one
service. In 1998, we were awarded the Data Communications magazine "Hot Product
of the Year" award for our Frame Relay service, marking the sixth time in seven
years we have won this award for innovative services. With the expansion of our
ATM backbone we will begin to offer to our clients a broader range of
innovative, value-added services, including voice, video and data. We intend to
continue developing these services to allow us to derive additional revenue
from our existing client base and to attract new clients.

                                       42
<PAGE>

 Strengthen our sales and customer support structure

      Our country representatives play a major role in the sales and marketing,
local client support and implementation of our services on a global basis. Our
country representative strategy has allowed us to expand geographically without
the related financial and managerial costs associated with building large
numbers of wholly-owned multinational sales and support operations. We are
constantly evaluating new opportunities to expand our sales channels through
the addition of new country representatives and alternate sales channel
partners. In the last three years, we have expanded into seven new countries
and have added 11 new alternate sales channel partners. Our strategy is to
capitalize on the strength of our country representatives and alternate sales
channel partners to build market share among multinational corporations.

 Provide the highest level of quality, security and reliability for our
 services

      We are committed to maintaining the highest level of quality, security
and reliability in delivering data communications services over our network.
Using our network management tools and systems, we are able to proactively
monitor our global network operations and respond quickly to client problems,
24-hours a day, seven days a week. We consistently meet or exceed our 99.7%
quality standard, reflecting our guarantee of network availability. In
addition, we support our clients through our extensive local operations. To
ensure this quality, we continue to make investments in client service and
support, and continually evaluate our performance in order to retain our valued
clients. We also continually hire and train experienced and technically
sophisticated network support and services personnel. We are committed to
adhering to these quality standards, in part by maintaining our ISO 9001
certification.

OUR SERVICE SOLUTIONS

      We provide services to meet clients' global data communications needs. We
offer clients either individual services that they can use as part of their own
networks or more integrated solutions that combine several of our services.
Examples of how our services and solutions meet our clients' needs include:

    .  For one of the world's oldest and largest luxury hotel companies, we
       connect the reservation systems of 300 hotels in 66 countries;

    .  For a global health care company, we manage data communications
       between 40 offices, 4,500 desktop computers and 6,000 employees
       around the world;

    .  For a major European commercial bank, we provide managed data
       communications services to branch offices in 66 cities located in
       Europe and Asia; and

    .  For a German freight services company, we connect offices in 40
       countries and integrate their different e-mail and messaging systems.

      Our services are organized into four categories: Network Services;
Consulting Integration and Provisioning Services; Application Services; and
Other Communications Services.

 Network Services

      We offer multinational corporations and our sales channel partners
private managed data services. Our clients use these services to manage
information among their worldwide locations. For example, manufacturing
companies use our services to integrate production and inventory schedules,
technology companies use our services to transmit design files and financial
institutions use our services to connect their trading desks. Typically,
clients employ these services to transmit information that is critical to their
daily operations. Within Network Services, we offer Frame Relay, ATM, Private
Internet, Global Internet, MultiMedia and Remote Access.

      Frame Relay Services. Our Global Frame Relay service is the largest
component of our Network Services. We offer three levels of Frame Relay service
to meet the specific performance characteristics of our

                                       43
<PAGE>

clients' applications. A premium level Frame Relay service is available for our
clients' mission-critical, interactive applications requiring the highest level
of performance and network availability. For example, clients use this service
to enhance the performance of and maximize their investment in enterprise
resource planning software. Clients use our second level Frame Relay service
for multi-protocol applications with less stringent response time requirements
such as remote printing, intranet browsing, collaborative software and large
file transfers. Our third level Frame Relay service is most suitable for
clients using applications with lower performance requirements which are less
sensitive to longer response times such as Internet browsing, e-mail and small
file transfers.

      ATM Services. We are in the process of commercializing our ATM service.
More advanced than Frame Relay and X.25 technology, ATM enables us to address
the rapidly emerging requirements for high speed integrated voice, video and
data services, as well as the delivery of bandwidth-intensive applications,
such as video conferencing and advanced voice, video and data services.

      Private Internet Services. As part of our Network Services, we offer our
clients a private Internet solution. Our Private Internet Services use IP to
provide corporate networks functionality similar to the public Internet but
with the performance characteristics of The World Network. This means that
clients can effectively run mission-critical applications using cost effective
Internet development tools on our high performance private network. Our Private
Internet Services are ideal for corporations seeking to establish extranets or
to engage in e-commerce.

      Global Internet Services. Global Internet Services provide dedicated and
dial-up connectivity to the public Internet. We offer our multinational clients
dedicated and dial-up public Internet access from our locations through a
series of peering agreements and transit relationships with other global ISPs.
This service is attractive because clients can deal with a single provider
instead of a different ISP in each country. We provide a completely managed
service with local support, network management and 24-hour operations. We also
produce one consolidated invoice for all services.

      MultiMedia Services. We provide high quality voice services, referred to
as our MultiMedia Services, which can be used independently or in combination
with our managed data services. We deliver high quality, cost-effective voice
services by using a technology that we developed with Nortel. We can easily add
office-to-office voice communications for clients that are using our managed
data services by connecting their voice telecommunications systems to The World
Network. We can also offer single-site companies such as shippers,
importers/exporters and telemarketers connections to the local public
telecommunications network. We can offer all of these voice services on a
single global invoice with location and call detail as well as customized dial-
plan capability. We expect to expand our MultiMedia Services to include video
services in the future.

      Remote Access Services. We offer our clients a variety of remote access
services on a wireline and wireless basis. Our remote access services provide
our clients' employees, who are travelling or who are located remotely, with
access to the same network applications that would be available if they were at
their primary office. Using our services, applications such as enterprise
resource planning, file sharing, Internet access and e-mail are accessible with
higher levels of security and performance than would normally be provided by
accessing these networks via the public Internet. We contract with one of the
industry's leading suppliers of enhanced security products to offer these
security products to provide greater security than traditional password
systems. As a result, our remote access service provides connectivity for
"virtual offices" anywhere in the world, quickly, securely and cost
effectively. We provide dial-up connectivity through The World Network to
insure secure access for our clients' employees, business partners and
customers. We also provide worldwide virtual private network connectivity for
remote offices and LANs that support small office/home office, business
partner/client support networks and basic Internet access requirements. We can
offer this service through telecommuters' home computers, through toll free
dial-up service or via mobile phones connecting to our network via the local
public telecommunications network or via access methods appropriate to wireless
data telephony.

                                       44
<PAGE>

 Consulting, Integration and Provisioning

      We offer integration, provisioning and implementation services to our
clients to implement the "last-mile" part of the solution. Our country
representatives provide the on-the-ground support and local implementation
necessary to deliver these services on a global basis. As part of the
integrated solution, the country representatives provision leased lines to
connect our clients' sites to The World Network. In addition, they procure,
install and maintain the appropriate customer premises equipment. We believe
few other global data communications service providers can provide these
localized services on a global scale and our local presence is a significant
competitive advantage. As part of the comprehensive solutions we offer, we also
provide consulting services to assist our clients in integrating our data
communications services into their operations.

 Application Services

      Our Application Services include messaging and collaboration services
that provide an attractive alternative for businesses that prefer to outsource
all of their "non-core" business messaging activities. We provide three types
of messaging and collaboration services. First, we host e-mail services for our
clients using Microsoft Exchange and Lotus Notes software. Our e-mail hosting
activities include management of the client servers, software support and
service, and e-mail translations to telex and fax. Second, we have developed a
proprietary global unified messaging and collaboration service and software
solution called MailMail. MailMail enables voicemail, fax, telex, paging and e-
mail messages to be aggregated and forwarded to a single e-mail location,
accessible via the public Internet. We offer MailMail as an alternate
enterprise wide e-mail service to our multinational clients, and we license it
to other ISPs. Third, our X.400 service enables our clients to exchange
information between different e-mail systems in a seamless and secure manner.

      We offer hosting of Web sites, referred to as Web hosting services, to
clients who wish to outsource their Web sites and other Internet applications.
We run clients' servers for them at an operations center with high bandwidth
Internet connectivity, redundant power and disaster recovery provisioning. We
can connect hosting centers to the clients' private network via Frame Relay
with guaranteed secure access using firewall security services.

 Other Communications Services

      Our highly reliable, widely available and cost-efficient X.25 service is
typically used for lower performance applications requiring secure
connectivity. X.25 is a widely deployed and proven technology frequently used
in developing countries where high speed transmission capacity is not
available.

GLOBAL NETWORK MANAGEMENT/LOCAL SUPPORT

      The World Network is the physical platform across which we deliver all of
our services. Our Global Network Management/Local Support infrastructure is the
combination of support, billing, management and personnel, which allows us to
offer our solutions seamlessly throughout the world.

      We deliver our services through an infrastructure comprised of
technology, connectivity, tools, processes and personnel. We provide seamless
global performance through our network of nodes, switches, circuits and
terminating devices, combined with the management systems and processes for
change, configuration, security, billing and accounting. Changes, upgrades and
enhancements to our network are possible given our common information,
management and tracking infrastructure.

      We develop client solutions through a collaborative effort among the
country representatives responsible for serving each client location. To ensure
the quality of the solution provided, an experienced global project management
team overseas the deployment of the client solution, using a highly-developed
set of systems, processes and infrastructure, which have been developed, tested
and improved over the last 30 years.

                                       45
<PAGE>

After installation, our integrated global billing system allows clients to
receive a single invoice for all services. We believe the time and capital
required to duplicate our global capabilities provides us with a significant
competitive advantage.

DEVELOPMENT OF INNOVATIVE SERVICES

      We are recognized in the industry as an innovative developer of products
and services. For example, Data Communications, a leading magazine covering
enterprise networking, has repeatedly recognized our achievements. In January
1998, it awarded us a "Hot Product of the Year" award for our innovative Frame
Relay technology. This marked the sixth time in seven years that an Infonet
service earned this distinguished award. In addition, we released multiple
levels of Frame Relay service in 1998 and IP service in 1991, in each case,
more than one year before our competitors. Designing solutions for our clients
keeps us closely involved with new market requirements, the most promising of
which are added to our ongoing service development programs.

CLIENT BASE

      We have more than 1,150 multinational clients which typically have
between 15 and 25 locations and are diversified across both industry groups and
geographic regions. We provide our services to many of the world's largest
multinationals including Allergan, Baan, Microsoft, Nestle, Nokia,
Pharmacia/Upjohn and Volkswagen. Our 29% share of the top 500 corporations in
Business Week's 1998 Global 1000, an annual list of the world's largest
corporations, is evidence of the central role that we play in the global data
communications industry. No single client comprised more than 2% of our
revenues in fiscal year 1999.

      A substantial portion of our revenues are under contract for one to three
years. The act of switching service providers not only has the potential to
compromise the security and performance of the client's network, but also
presents a significant inconvenience, particularly to larger clients using a
number of our services. Therefore, we believe that our larger clients typically
are reluctant to terminate their contracts with us.

COUNTRY REPRESENTATIVES

      Our country representative structure gives us global reach and strong
local presence in the countries in which we operate. The country representative
structure emerged from our historical relationship with major
telecommunications companies, such as Deutsche Telecom, Embratel (Brazil),
France Telecom, Korea Telecom, Singapore Telecom and Telekom Malaysia. We have
enjoyed strong relationships with our 56 country representatives. A total of 14
country representatives have been with us for more than ten years and 29 have
been with us for more than five years.

      Our consolidated country representatives consist of nine separate country
representatives that provide service in 14 countries. Our consolidated country
representatives accounted for approximately $152.4 million of our revenues in
fiscal year 1999, representing about 50% of total revenues. In addition to our
consolidated country representatives, we have 47 non-consolidated country
representatives which, together with our consolidated country representatives,
provide service in more than 60 countries. In the aggregate, our country
representatives accounted for approximately 90% of our revenues in fiscal year
1999.

      We are the principal service provider to our clients and control the
delivery of all services to them on an end-to-end basis. We centrally control
and configure our network and rely on our country representatives to deliver
our services and maintain The World Network locally. We rely on our country
representatives for insights into local operating, regulatory and market
conditions. They are involved in sales and marketing, operations, network
management and client support. Depending on the geographic location and needs
of a client, country representatives from different countries will collaborate
with each other when making sales presentations. Country representatives manage
accounts on a daily basis and are the first point of contact for clients,
generally providing service in the local language. To minimize our regulatory
hurdles, each country

                                       46
<PAGE>

representative is a party to a legal contract with the client. Once a new
client has signed a contract, we configure the network for the service and
coordinate with other country representatives to implement the solution for the
client. Our country representatives take a lead role in implementing the last-
mile part of the solution by provisioning leased lines and installing equipment
at the client site. In addition, the country representatives provide local
support for our services, operating our local network nodes and, in some cases,
housing and operating components of the infrastructure for specific services on
our behalf.

 Governance and Controls

      We have service agreements with all of our country representatives that
govern our relationships. The agreements are generally non-exclusive and are
essentially the same for all country representatives and generally have five
year terms. These agreements provide the country representatives with:

    .  the right to market and sell our services;

    .  the right to use our trademarks and service marks;

    .  access to operational and marketing documentation; and

    .  training materials and sessions.

      The agreements give us:

    .  the right to recommend prices;

    .  the right to jointly set revenue targets with the country
       representatives;

    .  the ability to terminate the agreement if the country representative
       fails to meet the revenue targets or if targets cannot be agreed upon
       for two consecutive years;

    .  the ability to determine staffing of the local office jointly with
       the country representatives; and

    .  in many cases, the right to appoint one of the three members of the
       Advisory Review Board, which governs the relationship between us and
       the country representative.

      The agreements outline the fees that the country representatives are
required to pay us for access to our network. In addition, the agreements
outline our compensation and pricing arrangements with the country
representatives.

THE WORLD NETWORK

 Overview

      We own and operate The World Network, one of the world's largest
commercial global data networks in terms of geographic coverage accessible from
over 180 countries. Our network supports several major protocols that allow us
to offer a broad range of services. Our network structure allows us to respond
quickly to our clients' changing needs for increased bandwidth, reliability and
security while enabling us to manage data traffic patterns efficiently. Because
we manage our network on an end-to-end basis, we are better able to control and
customize the services delivered to our clients. The World Network has 11,142
ports comprised of over 6,000 IP, Frame Relay and X.25 access and customer
premise devices which are connected by over 950,000 route-kilometers of data
transmission circuits, most of which are over fiberoptic routes.

                                       47
<PAGE>

      The World Network is based upon a three-tier hierarchical structure which
we believe provides a competitive advantage because it allows for efficient
traffic management, higher performance and reduced cost. This three-tiered
hierarchical structure is comprised of Global Switching Nodes, Regional
Switching/Access Nodes and Local Access Nodes as diagrammed below:


                             [CHART APPEARS HERE]


      Global Switching Nodes: We use our Global Switching Nodes cost
effectively to aggregate and distribute interregional network traffic flows.
Equipped with FORE Systems' high capacity ATM switches, these Global Switching
Nodes are capable of accepting multiple channel inputs of data in excess of 45
Mbps. Our Global Switching Nodes are connected by fiberoptic transmission
capacity and are currently located in the following ten locations: Amsterdam,
Dallas, Kuala Lumpur, London, London-Docklands, Los Angeles, New Jersey, New
York, Stockholm and Tokyo. We plan to add more additional Global Switching
Nodes to further expand and enhance our ATM-enabled network around the world
and to increase our transmission capacity to as high as 2.5 gigabits per
second, or Gbps.

      Regional Switching/Access Nodes: We use our Regional Switching/Access
Nodes to aggregate regional traffic and provide access to The World Network for
clients with bandwidth-intensive applications. These nodes are equipped with
Nortel Passport switches and Cisco hub and access routers. The Nortel Passport
switches provide Frame Relay capability as well as high capacity access (at
speeds of 2 Mbps to 45 Mbps) to the Global Switching Nodes through our
backbone. The Cisco hub and access routers provide high capacity

                                       48
<PAGE>

local access for our clients and aggregation services for regional IP traffic.
The Cisco hub routers can also use the Nortel Passport switches for connection
to the Global Switching Nodes to exchange data interregionally. Our 114
Regional Switching/Access Nodes are located in 48 countries around the world.

      Local Access Nodes: Our Local Access Nodes connect clients to The World
Network at speeds generally less than 2 Mbps. These nodes enable our clients to
connect to and use IP, X.25 and Frame Relay applications through dedicated and
dial-up access. The Local Access Nodes are equipped with Cisco access routers,
Nortel and Siemens X.25 devices and Ascend Dial Access devices. The Cisco
routers provide dedicated IP access, the Nortel and Siemens devices provide
dedicated access using X.25 and the Ascend devices provide dial-up access.
Local access is available in 125 locations in over 60 countries. We are also
able to extend our network reach to countries where the communications
infrastructure is not available by using satellite services, which are
integrated as part of The World Network.

 Local Access

      Clients can access The World Network either directly using a dedicated
line or through dial-up services by connecting through Local Access Nodes,
Regional Switching/Access Nodes, or via our interconnection with the national
data network of our local telecommunications partners. A country representative
arranges dedicated access through a leased line or via the national data
network of the local telecommunications partner. Dial-up services offer local
and remote access to The World Network through the local public
telecommunications network. We plan to offer additional access methods and
adapt them to our backbone for increased efficiency. Among those services
planned or under review for clients that require higher speed access are ATM,
digital subscriber line or DSL, and broadband wireless remote access. In remote
locations clients can access The World Network via satellite services. Clients
can choose to have us manage their entire provisioning and support at and
between each client location.

 Backbone Capacity

      Our backbone connects all nodes on The World Network. Traditionally, we
have obtained backbone capacity from major telecommunications carriers through
short-term leases. We have begun, and expect to continue, to purchase capacity
on major international and regional routes where it is economical to do so and
where capacity is available for purchase or long-term lease. We intend to
invest significant capital resources to expand and upgrade our network in order
to maintain our competitive advantage. We are currently in discussions with
several suppliers of terrestrial and intercontinental undersea cable. In
collaboration with Hughes Electronics, we are also using satellite technology
as a fill-in strategy to provide satellite links to The World Network where
terrestrial connections or alternative paths for specific high availability
applications may not be available. We increased our network capacity by more
than 500% in 1999, and we expect to continue to expand capacity as our clients
require.

 Network Protocols

      Our network strategy is to support a wide range of managed data
communications services over a common infrastructure. As such, our global
network infrastructure supports a variety of protocols including X.25, Frame
Relay, IP and ATM. Our existing Frame Relay network is the basis for our
delivery of seamless managed data communications services on a worldwide basis.
Moreover, by using Frame Relay technology we are able to capitalize efficiently
on The World Network's bandwidth to transport a variety of data traffic. We are
implementing the new industry-standard IP versions and extensions to
differentiate our network from other competitive networks. We intend to
introduce IP Version 6 into the network as it becomes commercially available.

      Our ATM-enabled network is able to support broadband services that
require asynchronous networking capabilities (for example, video services), as
well as provide transport for aggregated data between our Regional
Switching/Access Nodes and our Global Switching Nodes. We believe our ATM-
enabled network will be the transport platform for our managed data
communications services in the future. We expect our ATM-enabled network will
allow for the efficient and high-speed transport of voice, video and data
traffic over

                                       49
<PAGE>

a single network. This capability will not only enable us to further leverage
our network assets, but also allow us to capitalize on the demand for
anticipated new service offerings that combine voice, video and data.
Furthermore, as client demand for additional bandwidth, faster transmission
speeds and enhanced service quality increases for applications such as desktop
videoconferencing, we believe our investment in ATM technology will position us
as a leading provider of these services.

 Network Management

      We manage our network and monitor its operation 24-hours a day, seven
days a week through two network control centers located in Los Angeles and
Brussels and three global customer assistance centers in Los Angeles, London
and Tokyo. The customer support operations consist of multilingual,
technologically experienced staff in over 60 countries.

      Our network management infrastructure is an integral component of the
seamless delivery and management of our suite of services. We proactively
monitor the "real-time" status of over 10,000 network components that provide
performance feedback on a daily basis. Consistent information is available to
all global support entities using trouble tracking services, network alerts and
alarms, change configuration and security management processes. We continue to
enhance these capabilities by adding automation tools and providing on-going
training.

 Network Security

      We have built and maintain an advanced security and control structure.
Because we manage our global network from end-to-end, we maintain central
control of network access, operations and maintenance. We protect our network
through various means including firewalls, intrusion detection platforms,
network address translation, filtering, and network architecture structures, as
well as various dedicated network and remote access authentication processes.

 Backup Network Control Centers and Nodes

      We also have backup network control centers in Sacramento, California and
Chantilly, Virginia, which we created to assume network control center
operations in the event of a disaster or similar emergency. In addition, in
order to lower the potential exposure from major failures or disasters
affecting a node, we have implemented second nodes capable of assuming the
traffic of our primary nodes. The fiber connections in the area and, where
feasible, client access lines are split between the two nodes. Thus, transit
traffic through a city can continue to flow in the event of a major failure or
disaster affecting one of the nodes. We have implemented second nodes in the
London-Docklands, Los Angeles, New York, New Jersey, San Francisco and
Sacramento metropolitan areas.

 Circuit Diversity

      Nodes are connected with other nodes with at least two redundant
connections, so that no single connection failure will result in the isolation
of the node. The failure of a connection results in the automatic rerouting of
traffic to one or more alternate network paths. In the event of a node outage,
transit traffic is automatically rerouted to paths around the failed node. In
addition, we have, over our operating history, sought to ensure that our
circuits are, as much as possible, diversely routed so that a major failure by
a carrier in a given route does not result in a total network outage to our
clients.

 Disaster Recovery

      Under our Disaster Recovery Plan, we distribute our critical operations
over two to three global regions which constantly share information with one
another. These network control centers and customer

                                       50
<PAGE>

assistance centers are essentially self-contained units located in diverse
geographic regions, and thus provide natural disaster backup for each other as
described below:

    .  Network Control Centers in Los Angeles and Brussels;

    .  Global Customer Assistance Centers in Los Angeles, London and Tokyo;

    .  Second Level Customer Assistance in Los Angeles, Brussels and Tokyo;
       and

    .  Third Level Customer Assistance in Los Angeles and Brussels.

      Within the backbone, we have attempted to minimize the risk of node
outages by placing our nodes in highly secure facilities, and by requiring dual
cable entrances, diversely routed circuits and uninterruptable power supplies.
However, clients who need quick recovery from disasters or failures affecting a
node can supplement their service with our Failure Recovery Service option,
which provides access to an alternate Infonet node via a leased line, dial-up
access backup or satellite services. We provide this service on an automatic or
manual backup basis.

 Quality Standards

      We perform ongoing quality system audits and conduct client satisfaction
surveys. As a result, we receive constant performance feedback to ensure that
our quality systems meet client needs and our guarantee of 99.7% network
availability. We have been awarded ISO 9001 certification for several of our
services.

SALES AND MARKETING

 Direct Sales Channels

      Our country representatives are responsible for all of our sales
activities in their respective territories. Each country representative
maintains a sales force which directly calls on clients, coordinates the
contract signing process and manages accounts on a daily basis. We begin our
sales process by working with the client to gain an understanding of its
business needs so we can tailor a solution to meet its specific requirements.
The sales force for each country representative applies its knowledge of the
local operating, regulatory and market conditions to market our service
offerings effectively to best meet the needs of the local client base. In
addition, we provide centralized sales and marketing support for our country
representatives. We conduct sales training centrally and within each sales
region and use computerized training to reinforce classroom training. Direct
sales channels accounted for approximately 90% of our revenues in the year
ended March 31, 1999.

 Alternate Sales Channels

      Our global alternate sales structure is typically comprised of major
telecommunications companies and other value-added resellers. These sales
channel partners sell all or a portion of our suite of services in their
territories to clients that require one or more of our global network
communications services that the sales channel partners cannot supply
independently. Our sales channel partners often market these services under
their own brand names. We act as the "carrier's carrier" and/or as the product
development resource, providing global services to meet the sales channel
partners' specific needs. Multi-year contracts govern these relationships.
Alternate sales channels accounted for approximately 10% of our revenues in the
year ended March 31, 1999. The following are examples of our alternate sales
channel relationships:


    .  AT&T offers our services outside the U.S. to its U.S.-based clients.
       AT&T also offers global access to the AT&T InterSpan Frame Relay
       service using our Frame Relay dial-up and dedicated connectivity;

    .  MCI WorldCom has an agreement that allows it to offer global services
       to its U.S. customers in those countries where MCI WorldCom has no
       coverage; and

                                       51
<PAGE>

    .  Telstra, one of our stockholders and a leading telecommunications
       provider, has entered into an agreement with us which allows it to
       extend its global reach beyond Australia through The World Network.

 Promotion and Advertising

      We recognize that strong brand development and awareness is crucial in
obtaining and maintaining market share. Our promotional and advertising
programs include participation in business seminars and information technology
information/training sessions as well as advertising in selected network
computer publications.

      In 1999, we began a new global campaign to increase awareness of the
Infonet brand name and our service offerings. This campaign includes increased
spending on direct advertising, advertising in airports, major U.S. and
European newspapers, business magazines, trade magazines and inflight
magazines, as well as participation in trade shows and Internet marketing
campaigns.

ACCESS TO MULTINATIONAL CORPORATE CLIENTS OF KPN, SWISSCOM AND TELIA

      In our ongoing efforts to sell our services to multinational
corporations, on September 30, 1999, we entered into agreements with AUCS
Communications Services N.V., Unisource, the owner of AUCS, and the three
companies that own Unisource, KPN, Swisscom and Telia. KPN, Swisscom and Telia
are also our stockholders. See "Principal and Selling Stockholders."

      Our agreements with KPN, Swisscom and Telia will give us access to their
approximately 1,300 multinational corporate clients currently being served by
AUCS as well as additional multinational clients to which KPN, Swisscom and
Telia may provide services in the future. In exchange for the right to market
our services to their clients and $40.0 million in cash, we have issued an
aggregate of 1,600 shares of our Class B common stock to KPN, Swisscom and
Telia under stock purchase agreements.

      These multinational clients represented approximately 50% of AUCS
revenues over the past two years. We understand that no single multinational
client accounted for more than approximately 3% of AUCS revenues in 1998 and
that the top ten multinational clients accounted for approximately 15% of AUCS
revenues in 1998. Based on publicly available information, AUCS total
consolidated revenues for the 1998 calendar year were 875 million guilders, or
approximately $441 million according to the exchange rate on October 1, 1999.
AUCS total revenues include amounts derived from AT&T customers serviced by
AUCS, but we will not obtain access to these clients. In addition, AUCS
revenues include voice and other services that we provide on a limited basis or
not at all. Because it is not possible to predict the multinational clients'
future needs, the multinational clients' contribution to AUCS total revenue is
not indicative of any contribution they may make to our revenues.

      We have assumed the obligation to provide the multinational clients with
the services currently provided to them by AUCS under the terms of an agreement
that assigns existing distribution agreements to us. We also intend to sell
these multinational clients our services as a supplement or replacement for
services previously provided by AUCS and, over time, we expect to transition
the multinational clients onto The World Network. During the transition period,
we will continue to use the AUCS platform to deliver all or some of the
services provided to the multinational clients, which for convenience we refer
to as the AUCS services.

      We will obtain the AUCS services to be provided to the multinational
clients under the terms of a services agreement with AUCS, which is based on
our standard services agreement. The pricing of the AUCS services provides us
with an agreed-upon approximately 20% gross margin on the provision of these
services. The services agreement is terminable upon 180 days' notice by any
party.

      We also entered into a call option for the underlying tangible assets of
AUCS. Until September 2002, the option allows us to purchase any and all of the
AUCS tangible assets at fair market value not to exceed

                                       52
<PAGE>

$130 million. The call right allows us to purchase the assets of AUCS so that
we can continue to offer the AUCS services to our clients if the services
agreement is terminated. The call option may be subject to regulatory approval
and is conditioned upon AUCS ability to continue to fulfill its contractual
obligations to third parties.

      While we will attempt to transition the multinational clients to The
World Network as soon as possible, we expect the transition will be implemented
over a period of 12 to 18 months. Since we already have The World Network, an
existing sales and marketing force and other elements necessary to service
these multinational clients, we believe our infrastructure will be sufficient
to transition these clients. We have not purchased any assets from AUCS, and we
will not obtain the right to use the AUCS sales force or employees.

      The percentage of total revenues from the multinational clients
attributable to AUCS services and to our services is expected to vary depending
on the degree of the transition's success and the time necessary to transition
the multinational clients to The World Network. If the transition is not
effected quickly, the revenues attributable to AUCS services will remain a
larger percentage of our total revenues from the multinational clients than
that attributable to our services. As the transition is completed, and assuming
that the multinational clients continue as our clients after the transition,
the percentage of our total revenues attributable to our services, as compared
to that attributable to AUCS services, will correspondingly increase. Since the
multinational clients have no obligation to use our services, we cannot assure
you that all of the multinational clients will transition to our network, that
the multinational clients which do transition to our network will continue to
purchase our services or, if they continue to use our services after the
transition, that the multinational clients will purchase as many or more
services from us than they did from AUCS.

AUCS MANAGEMENT AGREEMENT

      We also entered into a three-year management agreement with AUCS on
September 30, 1999. For our management services, we will receive a quarterly
management fee equal to 1.5% of the total consolidated revenues of AUCS, up to
an aggregate maximum of (Euro)17.1 million, or $18.3 million as of October 7,
1999, over the term of the agreement. In addition, we will receive an incentive
payment equal to 100% of the amount by which the cumulative sum of AUCS EBITDA
losses during the initial three-year term is less than approximately
(Euro)295.3 million, or $316.9 million, or we must rebate to AUCS 25% of the
aggregate amount by which the cumulative sum of AUCS EBITDA losses during the
initial three-year term exceeds (Euro)295.3 million, or $316.9 million, subject
to a cap equal to the aggregate management fee. AUCS owner, Unisource, has the
right to terminate the agreement on 180 days' notice generally and 30 days'
notice if the cumulative EBITDA losses of AUCS exceed approximately
(Euro)368.3 million or $395.2 million during the three-year term of the
management agreement. From its formation in 1996 to December 31, 1998, AUCS
cumulative EBITDA losses were approximately $409 million. While we expect that
our management will improve the performance of AUCS during the three-year term
of the management agreement, we cannot assure you that AUCS losses will
decrease, that we will receive any incentive fee or that we will not have to
rebate all or part of our management fee.

INDUSTRY PARTICIPANTS AND COMPETITION

      The growth and potential size of the data communications industry has
attracted many new entrants as well as existing businesses from several
industries. Current and prospective industry participants include multinational
alliances, long distance and local telecommunications providers, systems
integrators, cable television and satellite communications companies, software
and hardware vendors, wireless telecommunications providers and national, local
and regional ISPs. In addition, we expect that the predicted growth of the data
communications market will attract other established companies and
multinational alliances. Further, there are established and start-up companies
building global networks and beginning to offer data communications as part of
a comprehensive communications services portfolio. Our competitors include
AT&T, BT, Equant, GlobalOne and MCI WorldCom and new entrants such as Global
Crossing and Qwest. We compete in highly fragmented markets. Most participants
specialize in specific segments of the market, such as

                                       53
<PAGE>

access and/or backbone provision, managed access, such as intranets and
extranets, application services such as Web hosting; security services, and
communication services, such as IP-based voice, fax and video services and
commercial e-mail. Many of these existing and potential competitors have
greater financial resources than we do.

      We believe that competition in the data communication market is mainly a
function of the ability to offer a broad variety of innovative services
available on a reliable network supported by an effective service organization.
We believe that the key factors to our competitive position in this market are:

    .  our global reach;

    .  our full range of value-added services;

    .  the reliability of our seamless global network; and

    .  our extensive country representative structure and the support it
       provides to our clients.

EMPLOYEES

      As of June 30, 1999, including our consolidated country representatives,
we had a total of approximately 824 employees, 210 of which are located
internationally. There are approximately 460 additional dedicated Infonet
personnel who are employed by our non-consolidated country representatives, all
of whom are based internationally. We have not experienced any work stoppages
and consider our relations with employees to be good. None of our employees is
represented by a labor union.

FACILITIES

      Our principal offices currently occupy over 107,000 square feet in El
Segundo, California pursuant to a long term lease which expires in November
1999 and then continues on a month-to-month basis at our option. We have
entered into a lease for approximately 150,000 square feet of new office space
in an adjacent building currently under construction. This new building is
being constructed to our specifications and is expected to be completed in
November 1999. We have a 90-day option beginning on the occupancy date to
purchase the building for approximately $33.0 million. Any purchase would be
funded from general corporate funds and may be augmented by a mortgage. Once
complete, this new building will also house our Los Angeles Network Control
Center.

      In addition, we lease sales offices domestically and internationally in a
variety of locations. These leases generally have terms of three to five years.
None of these offices is critical to our success, and we believe that suitable
additional or alternative space is available on commercially reasonable terms
as needed.

      We also lease facilities for our network control centers, global customer
assistance centers and engineering offices around the world. We lease these
facilities at commercial rates under standard commercial leases. We believe
that suitable space for these operations is generally available on commercially
reasonable terms as needed.

LEGAL PROCEEDINGS

      From time to time, we may be involved in litigation that arises in the
normal course of our business operations. As of the date of this prospectus, we
are not a party to any litigation that we believe could reasonably be expected
to have a material adverse effect on our business, financial condition or
results of operations.

REGULATION IN THE UNITED STATES

 Overview

      We operate as an unregulated provider of information services, as that
term is defined in the Communications Act of 1934, as amended, and as an
enhanced service provider, as that term is defined in the

                                       54
<PAGE>

Federal Communications Commission ("FCC") rules. In most foreign jurisdictions
we operate as a value-added network provider. Our operations currently are not
regulated by the FCC, the states or the governments in the other countries
where we operate. Although we do not operate as a common carrier, we hold
authorizations to provide international services in some countries on a common
carrier basis. We have obtained common carrier authorizations only in those
countries in which such authorizations are useful in securing more favorable
terms in our capacity or facilities leases or interconnection arrangements.
These authorizations require us to comply with specified regulatory filing and
reporting requirements. To the extent that we begin to offer regulated
telecommunications services as a common carrier, we will become subject to
additional rules and policies.

      Various existing U.S. federal and state regulations are currently the
subject of judicial proceedings, legislative hearings and administrative
proposals which could change, in varying degrees, the manner in which the
telecommunications industry operates. In addition, some foreign governments are
actively considering regulation of some of the services we offer. We cannot
predict the outcome of these proceedings, or the impact they may have on the
telecommunications or information services industries generally, or on us
particularly. In addition, we cannot assure you that future legislative,
regulatory or judicial changes in the United States or in other countries in
which we operate will not have a material adverse impact on our business.

 FCC Policy on Enhanced Services

      In 1980, the FCC created a distinction between "basic" services, which it
regulates as common carrier services, and "enhanced services," which remain
unregulated. The FCC exempted enhanced service providers from federal
regulations governing common carriers, including the obligation to pay access
charges and contribute to universal service. The Telecommunications Act of 1996
established a similar distinction between "telecommunications services" and
"information services." Changing technology and changing market conditions,
however, have made it increasingly difficult to discern the boundary between
unregulated and regulated services.

      In general, information services are value-added services that provide
access to regulated transmission facilities only as part of a services package
which also uses network or computer software to change or enhance the
information transmitted. We believe the services we provide come within this
definition. Because the regulatory boundaries in this area are unclear and
subject to dispute, however, the FCC could seek to characterize some or all of
our services as "telecommunications services." If that happens, our services
would become subject to FCC regulation, although the impact of that
reclassification is difficult to predict. In general, the FCC does not regulate
the rates, services, and market entry and exit of non-dominant carriers, but
does require them to contribute to universal service and comply with other
regulatory requirements.

 U.S. Licenses

      Although we do not currently provide regulated telecommunications
services, we are authorized under Section 214 of the Communications Act of
1934, as amended, to provide global switched, data, voice, value-added and
private line services on a common carrier basis. We received authorization to
provide these services as a facilities-based common carrier in January 1999 and
to provide these services as a reseller in July 1999. We obtained these
licenses because we believe they allow us to procure the facilities and
capacity we need between the U.S. and foreign points under more favorable terms
and at lower cost than we could otherwise obtain. Although we do not currently
provide regulated telecommunications services, our FCC licenses subject us to
certain reporting and filing requirements.

 FCC Regulatory Requirements

      As noted above, our operation of networks does not currently subject us
to regulation in the U.S. either at the federal or state level. As an
authorized international common carrier, however, we are regulated by the FCC.
In the United States, authorized international carriers are subject to various
annual reporting

                                       55
<PAGE>

requirements as a condition of their licenses. Each year, we must submit data
to the FCC concerning our international traffic as well as the status of our
international circuits. We must also file an annual employment report to comply
with the Commission's Equal Employment Opportunity policies. International
common carriers are also required to file a tariff containing the rates, terms
and conditions applicable to their services before initiating international
telecommunications services. If we fail to maintain proper federal tariffs or
certifications, or if there is any finding by the FCC that we are not operating
under permissible terms and conditions, this may result in an enforcement
action against us or an investigation, either of which could impose upon us
substantial penalties, including the loss of our licenses to provide
telecommunications services.

      If we begin providing interstate, international telecommunications
services on a common carrier basis, we will be required to file additional
reports concerning our interstate and international traffic revenues. We also
may be required to contribute a percentage of these revenues to governmental
funds including Universal Service, Telecommunications Relay Service, Number
Portability, and the administration of the North American Numbering Plan. We
will also be subject to annual regulatory fees assessed by the FCC.

 FCC Policies Applicable to Regulated International Traffic

      If we begin to operate as a common carrier, we will be required to comply
with additional FCC policies governing international common carriers. For
example, the FCC requires carriers such as us to report "significant
affiliations," as defined by the FCC, with global carriers that have market
power in the countries in which we operate. In addition, the FCC administers a
variety of international service regulations, including the international
settlements policy. The international settlements policy governs the
settlements between U.S. carriers and their foreign correspondents of the cost
of terminating traffic over each other's networks, as well as the accounting
rates for settlement. The FCC has considerably relaxed this policy in its
implementation of the 1997 World Trade Organization Agreement on Basic
Telecommunications ("WTO Agreement"), which went into effect in January 1998.
Representing 90% of worldwide telecommunications traffic, the 72 signatory
countries to the WTO Agreement agreed to open their telecommunications markets
to competition and foreign ownership. We believe that this agreement, and its
implementation by the signatory countries, will provide us with significant
opportunities to compete in markets in which we did not previously have access,
and to provide end-to-end facilities-based services to and from these
countries.

      The regulatory requirements that may affect our operations continue to
evolve as a result of the WTO Agreement, federal legislation, court decisions
and new and revised policies of the FCC. In particular, the FCC continues to
refine its international service regulations in order to promote competition,
to reflect and encourage deregulation in foreign countries and to reduce
international accounting rates toward cost. Among other things, these changes
may increase competition and alter our ability to compete with other similar
service providers or to introduce new services. Any change in applicable
regulatory requirements may have an impact on our operations in a way that we
cannot predict.

REGULATION IN NON-U.S. MARKETS

      Although most countries impose little or no regulation on our network
operations, the laws and regulations governing our services are under review in
many countries outside the U.S. and are subject to change. Consistent with our
strategy of obtaining licenses or authorizations to provide regulated services
when we are able to obtain more favorable facilities or capacity lease terms or
interconnection arrangements, we have obtained facilities-based authorization
to provide telecommunications services in the United Kingdom. We anticipate
filing requests for authorization in several other countries as well. In some
countries we are able to obtain the more favorable arrangements we seek simply
by notifying the relevant government authority that we intend to operate on a
common carrier basis. In other countries, we are engaging in discussions with
foreign regulators to determine whether we must apply for authorization in
order to acquire or lease facilities or interconnect with other carriers.

DIRECTORS' TERMS

      Members of our board of directors currently hold office and serve until
our next annual meeting of stockholders, or until their respective successors
have been elected. Our board of directors is currently comprised of seven
directors and we expect to add two additional independent members to our board
of directors within 90 days after the consummation of this offering. In
accordance with the terms of our restated certificate of incorporation,
effective upon the closing of this offering, the terms of office of the board
of directors will be divided into three classes: the Class I term will expire
at the annual meeting of stockholders to be held in        ; the Class II term
will expire at the annual meeting of stockholders to be held in        ; and
the Class III term will expire at the annual meeting of stockholders to be held
in        . The Class I directors will be        ,         and        , the
Class II directors will be         and         and the Class III directors will

the

                                       58
<PAGE>

initial classification, the successors to directors whose term will then expire
will be elected to serve from the time of election and qualification until the
third annual meeting following election. In addition, our restated certificate
of incorporation provides that the authorized number of directors will be
designated by our bylaws. Any additional directorships resulting from an
increase in the number of directors will be distributed among the three classes
so that, as nearly as possible, each class will consist of one-third of the
directors. This classification of the board of directors may have the effect of
delaying or preventing a change in control or change in management. Our
directors may be removed, with or without cause, by the affirmative vote of the
holders of a majority of the shares entitled to vote at an election of
directors. There are no family relationships among any of our directors and
executive officers.

EMPLOYEE BENEFIT PLANS

 1998 Stock Purchase Plan

      Our board of directors adopted a stock purchase plan, effective as of
October 20, 1998. The plan provides all employees designated by our board of
directors the ability to purchase shares of our Class C common stock. Our Class
C common stock is non-voting, but shares ratably with our Class A and Class B
common stock in any dividends. The plan is administered by the compensation
committee of our board of directors. We may issue up to 600 shares of Class C
stock under the plan. No shares of stock purchased under the plan are
transferable until we have effected an initial public offering.

      In April 1999, we sold 315.87 shares of our Class C common stock to our
key employees pursuant to our 1998 Stock Purchase Plan. In accordance with the
provisions of the Stock Purchase Plan, some employees purchased their shares
for cash and other employees received their shares in exchange for a secured,
recourse promissory note held by us. Each share was sold for $25,000, which
price was set by the pricing formula at the time of the sales. All shares of
our Class C common stock will convert into Class B common stock prior to the
consummation of this offering.

 1998 Stock Option Plan

      In October 1998, we adopted our 1998 Stock Option Plan. We may issue up
to 300 shares of our Class C common stock under the plan. The specific terms of
the options issued is to be determined at the time of issuance by the
compensation committee of our board of directors. The exercise price for shares
issued under the plan may be no less than the value of the shares determined by
a pricing formula based on a multiple of our consolidated historic revenues.
Shares of stock purchased under the plan may not be traded or exchanged prior
to our initial public offering. The plan terminates on October 20, 2008, unless
terminated earlier pursuant to its terms.

      In April 1999, we issued options to purchase 124 shares of our Class C
common stock to 29 employees under our 1998 Stock Option Plan. Each option was
evidenced by an option agreement. The exercise price for each option is $25,000
per share. Each option award vests in 20% portions on December 31 of each year
from 1999 to 2004. All shares of our Class C common stock will convert into
Class B common stock prior to the consummation of this offering.

 1999 Stock Option Plan

      We intend to adopt a new stock option plan prior to the consummation of
this offering.

 Pension Plan


      Our pension plan is a contributory defined pension plan in which
substantially all of our domestic employees are eligible to participate. The
pension benefits received by a retiring employee are calculated by multiplying
the employee's total eligible compensation by 2.25%. Eligible compensation
consists of base compensation plus nondiscretionary bonuses and commissions.
Compensation deferred under the Infonet Deferred Income Plan, income related to
the 1998 Stock Option Plan, reimbursements, fringe benefits or other forms of
special pay are not eligible compensation.

      As of March 31, 1999, Jose A. Collazo, Ernest U. Gambaro, Akbar H.
Firdosy, John C. Hoffman and Michael J. Timmins, upon retirement at age 65,
would be entitled to annual retirement benefits of $46,621, $46,384, $15,547,
$18,762, and $20,924.

 Supplemental Executive Retirement Plan

      We also have a Supplemental Executive Retirement Plan, or SERP, which is
a non-qualified, non-contributory pension plan. Our SERP is a defined benefit
retirement plan for specified key officers and executives and provides for
benefits based on years of service, the age of the participant, and the
participant's average compensation during his or her final period of employment
under the SERP.

                                       61

 Stock Appreciation Rights Plan

      The stock referred to in the SARs Plan is our Class B common stock. The
SARs vest at 25% per year over four years with the first quartile vesting on
January 1, 2001. The SARs Plan terminates on October 20, 2004 or earlier if
specified conditions of the SARs Plan have been fully met.

 Deferred Income Plan

      The Infonet Deferred Income Plan, or IDIP, is a nonqualified deferred
income plan for employees earning over a prescribed amount. Participants may
defer receipt of compensation, which is held by us in trust and is invested in
accordance with the participants' directions.

                           RELATED PARTY TRANSACTIONS

STOCKHOLDERS AGREEMENT

      Immediately prior to the consummation of this offering, we expect to
enter into a stockholders agreement with all of our Class A stockholders. This
stockholders agreement provides that each Class A stockholder holding at least
400 shares of our Class A common stock will have the right to designate one of
our directors, and each Class A stockholder will agree to vote all of its
shares of common stock in favor of the directors designated by the other Class
A stockholders and for our president as a director. Accordingly, seven of the
nine directors on our board will be appointed by our Class A stockholders. Each
Class A stockholder will have a right of first refusal to acquire Class A
common stock proposed to be sold by another Class A stockholder. We will agree
in the stockholders agreement to include the Class A stockholders' stock in a
registered offering of stock by us commonly referred to as piggyback
registration and to undertake a registered offering of Class B common stock
upon demand by any Class A stockholder. Each Class A stockholder will agree to
maintain a country representative to support our marketing efforts and our
clients in that stockholder's home country.

COMMERCIAL CONTRACTS WITH RELATED PARTIES

      Some of our country representatives are related parties where either
(1) we hold more than twenty but less than fifty percent ownership interest or
(2) a country representative is owned, directly or indirectly, by one of our
stockholders. In each such case, our agreement with the related party acting as
our country representative is our standard service agreement. Each service
agreement has a term of four or five years, and gives the country
representative the right to sell our services and use our trademarks, marketing
and operating documentation and our training materials and services. In the
agreements, we receive the right to set revenue targets, terminate the
agreement if the revenue targets are not met, jointly determine staffing of the
country office with the country representative and appoint members of the
country representative's advisory review board. The agreements outline monthly
fees the country representatives pay us for access to our network and the fees
we pay the country representatives for the service and customer support.
Additionally, we have alternate sales channel agreements with some of our
stockholders that allow these stockholders to resell our services under their
brand names or to package them with other services they provide to their
customers. These alternate sales channel agreements are generally under the
same terms as alternate sales channel agreements we enter into with other
communications providers. In 1999, $88.3 million of total revenues were
generated by all of these related parties and $40.0 million of total country
representative compensation resulted from a related party acting as our country
representative.

      From time to time we lease transmission capacity from our stockholders
where they are existing local carriers. These leases are short term and at
tariff rates in regulated markets and at standard market rates in unregulated
markets.

RECENT CONTRACTS WITH OUR STOCKHOLDERS

      We recently entered into a number of agreements with our stockholders,
KPN, Swisscom and Telia, as well as a number of their affiliates. As part of
the agreements, our stockholders have agreed to indemnify us and we have agreed
to indemnify them for certain breaches of representations and warranties. For
additional information, please read the sections entitled "Business--Access to
Multinational Corporate Clients of KPN, Swisscom and Telia" and "Business--AUCS
Management Agreement," as well as the applicable risks disclosed in our "Risk
Factors."

LOANS TO OUR SENIOR MANAGEMENT

      In connection with our 1998 Stock Purchase Plan, several members of our
management team borrowed the purchase price for their stock pursuant to terms
of the plan. Persons borrowing from us entered into loan, pledge and security
agreements. In addition, the loan is full recourse to the borrower. Each loan
is at an annual interest rate of five percent. The amounts loaned to each

    of the closing of this offering upon the exercise of all options and other
    rights beneficially owned by the indicated stockholders on that date.
    Beneficial ownership is determined in accordance with the rules of the
    Securities and Exchange Commission, or SEC, and includes voting and
    investment power with respect to shares. Unless otherwise indicated, the
    persons named in the table have sole voting and sole investment control
    with respect to all shares beneficially owned.

                          DESCRIPTION OF CAPITAL STOCK

      The following description of our capital stock and provisions of our
certificate of incorporation and our bylaws are summaries and are qualified by
reference to the provisions of our certificate and our bylaws. Copies of these
documents have been or will be filed with the SEC as exhibits to our
registration statement, of which this prospectus forms a part. The description
of our capital stock reflects changes to our capital structure that will occur
upon the closing of this offering in accordance with the terms of our
certificate.

      Our authorized capital stock consists of 250 million shares of Class A
common stock, par value $0.01 per share, 500 million shares of Class B common
stock, par value $0.01 per share, and 50 million shares of preferred stock, the
rights and preferences which may be established upon issuance by the Board of
Directors. As of June 30, 1999, there were 5,718.83 shares of Class A common
stock, 6,781.17 shares of Class B common stock, and 315.87 shares of Class C
common stock outstanding and held of record by an aggregate of 36 stockholders.
Prior to the closing of this offering, the Class C common stock will
automatically convert to Class B common stock.

COMMON STOCK

      Holders of Class B common stock are entitled to one vote for each share
held on all matters submitted to a vote of stockholders and they do not have
cumulative voting rights. Holders of Class A common stock are entitled to ten
votes for each share on all matters submitted to a vote of stockholders and
they do not have cumulative voting rights. Accordingly, holders of a majority
of the shares of Class A common stock entitled to vote in any election of
directors may elect all of the directors standing for election. However, the
holders of the Class B common stock have the exclusive right to elect two
independent directors. Holders of Class A and Class B common stock are entitled
to receive ratably those dividends, if any, as may be declared by our board of
directors out of funds legally available for that purpose, subject to any
preferential dividend rights of any preferred stock. Upon any liquidation,
dissolution or winding up, the holders of Class A and Class B common stock are
entitled to receive ratably our net assets available after the payment of all
debts and other liabilities and any prior rights of any outstanding preferred
stock. Holders of our Class A common stock have pre-emptive rights to acquire
additional shares of Class A common stock that may be issued, as well as a
right of first refusal upon proposed transfers from other Class A stockholders,
but they have no redemption or conversion rights other than from Class A to
Class B common stock on a one-for-one basis. Holders of our Class B common
stock have no preemptive, subscription, redemption or conversion rights. The
rights, preferences and privileges of holders of both Class A and Class B
common stock are junior to, and may be adversely affected by, the rights of the
holders of shares of any series of preferred stock which we may designate and
issue in the future.

PREFERRED STOCK

      Our board of directors is authorized, subject to any limitations
prescribed by Delaware law, to issue shares of preferred stock in one or more
series, to establish from time to time the number of shares to be included in
each series, to establish or alter the voting powers, designations, preferences
and other rights, or the qualifications, limitations or restrictions of the
series, and to increase (but not above the total number of authorized shares of
the class) or decrease (but not below the number of shares of the series then
outstanding) the number of shares of any series without any further vote or
action by our stockholders. Our board of directors is also authorized to issue
preferred stock with voting, conversion and other rights and preferences that
could adversely affect your voting power or other rights, as a holder of common
stock. Although we have no current plans to issue any preferred stock, the
issuance of preferred stock or of rights to purchase preferred stock could have
the effect of making it more difficult for a third party to acquire, or of
discouraging a third-party from attempting to acquire us. An issuance could
also dilute your voting power or other incidents of ownership as a holder of
common stock. Upon the closing of this offering, there will be no shares of
preferred stock outstanding.

REGISTRATION RIGHTS

      Pursuant to the terms of the stockholders agreement, after the closing of
this offering the holders of Class A common stock will be entitled to require
us to register some or all of their Class B shares under the Securities Act if
we make a subsequent offering of our common stock or if any holder of Class A
common stock demands registration. We will bear the costs and expenses
attributable to the registration.

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

      We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. Subject to exceptions, Section 203 of the Delaware General
Corporation Law prohibits a publicly-held Delaware corporation from engaging in
a "business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an
interested stockholder, unless the interested stockholder attained that status
with the approval of the board of directors or unless the business combination
is approved in a prescribed manner. A "business combination" includes, among
other things, a merger or consolidation involving us and an interested
stockholder and the sale of more than 10% of our assets. Although there are
limited exceptions, an "interested stockholder" is a person who, together with
affiliates and associates, owns, or within three years did own, 15% of our
voting stock. This statute could prohibit or delay the accomplishment of
mergers or other takeover or change in control attempts with respect to us and,
accordingly, may discourage attempts to acquire us. A Delaware corporation may
opt out of the anti-takeover law with an express provision in its original
certificate of incorporation or an express provision in its certificate of
incorporation or bylaws resulting from amendments approved by the holders of at
least a majority of the corporation's outstanding voting shares. We have opted
out of this provision of the anti-takeover law.

      In addition, provisions of our certificate and bylaws that will be in
effect upon the closing of this offering and are summarized in the following
paragraphs, may be deemed to have anti-takeover effects and may delay, defer or
prevent a tender offer or takeover attempt that a stockholder might consider in
its best interest, including those attempts that might result in a premium over
the market price for the shares held by stockholders. These provisions may also
have the effect of preventing changes in our management.

      Our certificate authorizes our board of directors to fill vacant
directorships or increase the size of our board of directors. This may deter a
stockholder from removing incumbent directors and simultaneously gaining
control of our board of directors by filling the vacancies created by that
removal with its own nominees.

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

      Our certificate and bylaws contain other provisions that may be deemed to
have anti-takeover effects, such as the staggering of our board of directors
into three classes, the requirement of a supermajority vote to call special
meetings of our stockholders and a limit on the maximum number of directors.
These provisions could delay, defer or prevent a tender offer or takeover
attempt. In addition, the Class A stockholders will be able to exercise control
over all matters requiring approval by our stockholders, including the approval
of significant corporate transactions.

      The Delaware General Corporation Law provides generally that the
affirmative vote of a majority of the shares entitled to vote on any matter is
required to amend a corporation's certificate of incorporation or bylaws,
unless a corporation's certificate of incorporation or bylaws, as the case may
be, requires a greater percentage. Our certificate of incorporation and bylaws
provide that the affirmative vote of 95% of the Class A common stock entitled
to vote is required to amend our certificate of incorporation and bylaws.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS

      Our certificate of incorporation provides that, except to the extent
prohibited by the Delaware General Corporation Law, our directors are not
personally liable to us or our stockholders for monetary damages for any breach
of fiduciary duty as our directors. Under the Delaware General Corporation Law,
our directors have a fiduciary duty to us that is not eliminated by this
provision of our certificate of incorporation and, in appropriate
circumstances, equitable remedies such as injunctive or other forms of
nonmonetary relief will remain available. In addition, each director will
continue to be subject to liability under the Delaware General Corporation Law
for breach of the director's duty of loyalty to us or our stockholders, for
acts or omissions which are found by a court of competent jurisdiction to be
not in good faith or that involve intentional misconduct, or knowing violations
of law, for actions leading to improper personal benefit to the director, and
for payment of dividends or approval of stock repurchases or redemptions that
are prohibited by the Delaware General Corporation Law. This provision also
does not affect the directors' responsibilities under any other laws, such as
the Federal securities laws or state or Federal environmental laws.

      The Delaware General Corporation Law provides further that any
indemnification will not be deemed exclusive of any other rights to which the
directors and officers may be entitled under a corporation's bylaws, any
agreement, a vote of stockholders or otherwise. Our certificate of
incorporation eliminates the personal liability of directors to the fullest
extent permitted by the Delaware General Corporation Law and provides that we
may fully indemnify any person who was or is a party or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding
(whether civil, criminal, administrative or investigative) by reason of the
fact that such person is or was a director or officer of ours or is or was
serving at our request as a director or officer of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise,
against expenses (including attorney's fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by the person in connection with
the action, suit or proceeding.

      We have entered into agreements to indemnify our directors and executive
officers, in addition to the indemnification provided for in our bylaws. We
believe that these provisions and agreements are necessary to attract and
retain qualified directors and executive officers. Our bylaws also permit us to
secure insurance on behalf of any officer, director, employee or other agent
for any liability arising out of his or her actions, regardless of whether the
Delaware General Corporation Law would permit indemnification. We have
liability insurance for our officers and directors.

      At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under our certificate of incorporation. We are not aware
of any threatened litigation or proceeding that may result in a claim for
indemnification.

TRANSFER AGENT AND REGISTRAR

      Upon the closing of this offering, the transfer agent and registrar for
the Class B common stock will be              .

                         DESCRIPTION OF CREDIT FACILITY

THE SENIOR SECURED CREDIT AGREEMENT

      We entered into a senior secured credit agreement with a syndicate of
lenders arranged by Merrill Lynch & Co., which included The Bank of Nova
Scotia, as administrative agent, Societe Generale, as documentation agent and a
number of financial institutions and other entities as lenders. The credit
agreement provides for the following facilities:

    .  Delayed Draw Term Loan Facility. This is a seven-year delayed-draw
       term loan facility in an aggregate principal amount equal to $100.0
       million available to be drawn until August 20, 2000. The initial draw
       under the facility was used to repay existing indebtedness and fees
       and expenses in connection with the bridge loan facility. The
       proceeds of future draws can be used for our general working capital
       needs as well as those of our subsidiaries, including for capital
       expenditures. The delayed draw term loans are required to be repaid
       in 20 consecutive quarterly installments, commencing on September 30,
       2001. Amounts borrowed and repaid under this facility cannot be
       reborrowed.

    .  Tranche B Term Loan Facility. This is a seven-year term loan facility
       in an aggregate principal amount equal to $50.0 million. The tranche
       B term loan was drawn in full on August 20, 1999, the closing date of
       the credit agreement, and was used to repay our existing indebtedness
       under the bridge loan facility. The tranche B term loan is required
       to be repaid in 28 consecutive quarterly installments, commencing on
       September 30, 1999. Amounts borrowed and repaid under this facility
       cannot be reborrowed.

    .  Revolving Credit Facility. This is a six-year revolving credit
       facility in an aggregate principal amount equal to $100.0 million.
       Loans made under this facility are to be used for our general working
       capital needs as well as those of our subsidiaries, including capital
       expenditures. Amounts borrowed and repaid under this facility can be
       reborrowed during the six-year availability period. This facility
       contains a $10.0 million sub-limit for letters of credit.

OPTIONAL AND MANDATORY PREPAYMENT

      The loans under each facility may be prepaid without premium or penalty
at our option. The term loans are also subject to mandatory prepayment with:

    .  100% of the net proceeds of specified indebtedness (excluding the
       first $100.0 million of senior subordinated indebtedness);

    .  50% (reduced to 25% upon satisfaction of a leverage ratio) of the net
       proceeds of any equity issuance (excluding the first $750.0 million
       realized from an initial public offering by us);

    .  100% of the net proceeds of specified asset sales or dispositions (or
       payments received in respect of property or casualty insurance
       claims); and

    .  beginning in our 2002 fiscal year, 50% (reduced to 25% upon
       satisfaction of a leverage ratio) of excess cash flow.

      The revolving credit loans are subject to mandatory prepayment (with an
accompanying permanent reduction of the commitments under the revolving credit
facility) with:

    .  100% of the net proceeds of specified indebtedness (excluding the
       first $100.0 million of senior subordinated indebtedness); and

    .  100% of the net proceeds of specified asset sales or dispositions (or
       payments received in respect of property or casualty insurance
       claims).

                                       69
<PAGE>

      Mandatory prepayments are applied first to pay down the term loans and
second to pay down the revolving credit loans. As long as any delayed draw term
loans are outstanding, each tranche B term loan lender has the right to refuse
all or any part of any optional or mandatory prepayment that would otherwise be
allocated to its tranche B term loans. Any tranche B prepayment amount refused
will instead be applied to prepay the delayed draw term loans.

INTEREST RATES AND FEES

      Interest on the loans is payable, at a variable rate based on, at our
option, either the base rate or the eurodollar rate, in each case, plus a
margin. The margin for term loans (and, prior to February 20, 2000, for
revolving credit loans) is fixed by facility and by type of loan at the rates
specified in the credit agreement and ranges from 1.50% to 2.75%. From and
after February 17, 2000, the margin for revolving credit loans varies depending
on the ratio of our total indebtedness to consolidated EBITDA and ranges from
0.50% to 2.50%. Eurodollar loans are available, at our option, with an interest
period of one, two, three or six months and, if available to all relevant
lenders, twelve months.

      Under our credit agreement, we are required, by February 17, 2000, to
enter into hedge agreements to provide that at least 50% of the outstanding
term loans are subject to either a fixed interest rate or interest rate
protection for a period acceptable to the administrative agent.

      We are required to pay the lenders under the delayed draw term loan
facility and the revolving credit facility commitment fees, at a variable rate
depending on our level of borrowing under each facility, on the available
undrawn amount under each facility. The commitment fee rate varies from 0.50%
to 1.00%. Commitment fees are payable quarterly in arrears. We are also
required to pay an annual administration fee to the administrative agent and
certain other fees pursuant to a fee letter with Merrill Lynch & Co. and one of
its affiliates.

COLLATERAL

      Our obligations under the credit agreement and the other loan documents
are secured by liens granted by us and our domestic subsidiaries on
substantially all of our tangible assets located in the United States and on
all of our intangible assets. The collateral includes intellectual property and
all of the capital stock of each of our direct and indirect domestic
subsidiaries and 65% of the capital stock of any foreign subsidiaries owned
directly by us or any of our domestic subsidiaries, now owned or hereafter
acquired. Various assets and properties, including our new corporate
headquarters and our Maryland data center facility, are expressly excluded from
the collateral.

      In addition, the payment and performance of our obligations under the
credit agreement and the other loan documents are guaranteed by our domestic
subsidiaries and a Belgian subsidiary.

RESTRICTIONS

      The credit agreement contains representations, warranties, covenants
(including affirmative, negative and financial covenants) and events of
default, including nonpayment of principal and interest, violations of
covenants and the incurrence of material judgments, each of which are customary
for transactions of this type.

      The financial covenants require compliance with a minimum consolidated
fixed charge coverage ratio, a maximum consolidated leverage ratio and a
minimum consolidated interest coverage ratio. The credit agreement also
contains limitations on permitted capital expenditures.

      Certain other negative covenants restrict our ability and our
subsidiaries' ability to, among other things, incur debt, make investments or
acquisitions, grant liens, dispose of property, pay dividends or make other
restricted payments.

      For purposes of the loan documents, Networks Telephony Corporation and
Osiware International S.A. are deemed not to be our subsidiaries.

                        SHARES ELIGIBLE FOR FUTURE SALE

      Prior to this offering, there has not been any public market for our
Class B common stock, and no prediction can be made as to the effect, if any,
that market sales of shares of Class B common stock or the availability of
shares of Class B common stock for sale will have on the market price of our
Class B common stock. Nevertheless, sales of substantial amounts of Class B
common stock in the public market, or the perception that such sales could
occur, could materially and adversely affect the market price of our Class B
common stock and could impair our future ability to raise capital through the
sale of our equity securities. See "Risk Factors--If we or our existing
stockholders sell additional shares of our Class B common stock after the
offering, it could cause the market price of our Class B common stock to
decline."

      Upon the closing of this offering, we will have an aggregate of
shares of Class B common stock outstanding, assuming no exercise of outstanding
options. Of the outstanding shares, the shares sold in this offering will be
freely tradable, except that any shares held by our "affiliates," as that term
is defined under Rule 144 of the Securities Act of 1933, as amended, or the
Act, may be sold only in compliance with the limitations described below. The
remaining         shares of Class B common stock will be deemed "restricted
securities" as defined under Rule 144. Restricted securities may be sold in the
public market only if registered or if they qualify for an exemption from
registration under Rules 144, 144(k) or 701 of the Act, which rules are
summarized below.

      Subject to the lock-up agreements described below and the provisions of
Rules 144, 144(k) and 701, additional shares of our Class B common stock will
be available for sale in the public market as follows:

                 MATERIAL UNITED STATES INCOME TAX CONSEQUENCES
                              FOR NON-U.S. HOLDERS

OVERVIEW

      The following general discussion summarizes certain of the material U.S.
federal income and estate tax aspects of the ownership and disposition of Class
B common stock applicable to non-U.S. holders of Class B common stock. In
general, a "non-U.S. holder" is a person other than:

    .  a citizen or resident of the United States,

    .  a corporation or other entity taxable as a corporation created or
       organized under the laws of the United States or any of its political
       subdivisions,

    .  an estate the income of which is subject to U.S. federal income
       taxation regardless of its sources,

    .  a trust if a U.S. court is able to exercise primary supervision over
       administration of the trust and one or more U.S. persons have
       authority to control all substantial decisions of the trust; or

    .  a trust that has a valid election in effect under applicable U.S.
       Treasury regulations to be treated as a United States person.

      The discussion is based upon the Internal Revenue Code of 1986, as
amended, regulations of the Treasury Department, Internal Revenue Service
rulings and pronouncements and judicial decisions now in effect, all of which
are subject to change (possibly on a retroactive basis). The discussion does
not address aspects of U.S. federal taxation other than income and estate
taxation and does not address all aspects of federal income and estate
taxation. The discussion does not consider any specific facts or circumstances
that may apply to a particular non-U.S. holder and does not address all aspects
of U.S. federal income tax law that may be relevant to non-U.S. holders that
may be subject to special treatment under such law, such as insurance
companies, tax-exempt organizations, financial institutions, broker-dealers,
certain U.S. expatriates, controlled foreign corporations, passive foreign
investment companies or foreign personal holding companies.

      PERSONS CONSIDERING THE PURCHASE OF CLASS B COMMON STOCK SHOULD CONSULT
THEIR TAX ADVISORS CONCERNING THE APPLICATION OF U.S. FEDERAL INCOME TAX LAWS,
AS WELL AS THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION TO THEIR
PARTICULAR SITUATIONS.

DIVIDENDS

      In general, the gross amount of dividends paid to a non-U.S. holder will
be subject to U.S. withholding tax at a 30% rate, or any lower rate prescribed
by an applicable tax treaty, unless the dividends:

    .  are effectively connected with a trade or business carried on by the
       non-U.S. holder within the United States and a Form 4224 is filed
       with the withholding agent, or

    .  if a tax treaty applies, are attributable to a United States
       permanent establishment of the non-U.S. holder.

      If either exception applies, the dividend will be taxed at ordinary U.S.
federal income tax rates. A non-U.S. holder may be required to satisfy certain
certification requirements in order to claim the benefit of an applicable
treaty rate or otherwise claim a reduction of, or exemption from, the
withholding obligation under the above described rules. In the case of a non-
U.S. holder that is a corporation, effectively connected income may also be
subject to an additional branch profits tax, which is generally imposed on a
foreign corporation at a rate of 30% of the deemed repatriation from the United
States of "effectively connected earnings and profits" or such lower rate as an
applicable tax treaty may provide. To the extent a distribution exceeds our
current or accumulated earnings or profits, it will be treated first as a
return of the holder's tax basis, and then as a gain from the sale of a capital
asset. Any withholding tax on a distribution in excess of our accumulated
earnings or profits is refundable to the non-U.S. holder upon filing an
appropriate claim with the Internal Revenue Service.

                                       73
<PAGE>

      Under current law, dividends paid to an address outside the United States
are presumed to be paid to a resident of such country (unless the payor has
knowledge to the contrary) for purposes of the withholding tax discussed above
and, under the current interpretation of United States Treasury regulations,
for purposes of determining the applicability of a tax treaty rate. Under
recently finalized United States Treasury regulations, a non-U.S. holder of
Class B common stock who wishes to claim the benefit of an applicable treaty
rate (and avoid backup withholding as discussed below) for dividends paid after
December 31, 2000, will be required to satisfy applicable certification and
other requirements.

DISPOSITION OF COMMON STOCK

      Generally, a non-U.S. holder will not be subject to U.S. federal income
tax on any gain recognized upon the disposition of Class B common stock unless:

    .  the gain is effectively connected with a trade or business carried on
       by the non-U.S. holder within the United States, or, alternatively,
       if a tax treaty applies, attributable to a United States permanent
       establishment maintained by the non-U.S. holder, in which case such
       gain will be subject to tax at the rates and in the manner applicable
       to U.S. persons, and, if the holder is a foreign corporation, the
       branch profits tax may also apply,

    .  the Class B common stock is disposed of by an individual non-U.S.
       holder, who holds the Class B common stock as a capital asset and is
       present in the United States for 183 days or more in the taxable year
       of the disposition and certain other conditions are met, in which
       case such gain will be subject to a flat 30% tax, which may be offset
       by United States source capital losses even though the individual is
       not considered a resident of the United States, or

    .  (A) we are or have been a "U.S. real property holding corporation"
       within the meaning of Section 897(c)(2) of the Code at any time
       within the shorter of the five-year period preceding such disposition
       or such non-U.S. holder's holding period and (B) assuming that the
       Class B common stock is "regularly traded on an established
       securities market" for U.S. federal income tax purposes, the non-U.S.
       holder held, directly or indirectly, at any time during the
       applicable period from clause (A) above, including on the date of
       disposition, more than 5% of the outstanding Class B common stock. We
       are not and do not anticipate becoming a "U.S. real property holding
       corporation."

      Non-U.S. holders should consult applicable treaties, which may exempt
from U.S. taxation gains realized upon the disposition of Class B common stock
in certain cases.

ESTATE TAX

      Common stock owned, or treated as owned, by an individual non-U.S. holder
at the time of death will be includible in the individual's gross estate for
U.S. federal estate tax purposes, and may be subject to U.S. federal estate
tax, unless an applicable treaty provides otherwise.

INFORMATION REPORTING AND BACKUP WITHHOLDING

      On October 6, 1997, the Internal Revenue Service issued final regulations
relating to withholding, information reporting and backup withholding that
unify current certification procedures and forms and clarify reliance
standards. The final regulations generally will be effective for payments made
after December 31, 2000.

      Except as provided below, this section describes rules applicable to
payments made on or before December 31, 2000. Backup withholding, which
generally is a withholding tax imposed at the rate of 31% on certain payments
to persons that fail to furnish the information required under the U.S.
information reporting

                                       74
<PAGE>

and backup withholding rules, generally will not apply to (1) dividends paid to
non-U.S. holders that are subject to the 30% withholding discussed above, or
that are not so subject because a tax treaty applies that reduces or eliminates
such 30% withholding, or (2) dividends paid on the Class B common stock to a
non-U.S. holder at an address outside the United States, unless the payor has
actual knowledge that the payee is a U.S. person. We will be required to report
annually to the Internal Revenue Service and to each non-U.S. holder the amount
of dividends paid to, and the tax withheld from, such holder, regardless of
whether any tax was actually withheld or whether withholding was required. The
information may also be made available to the tax authorities in the non-U.S.
holder's country of residence.

      In the case of a non-U.S. holder that sells Class B common stock to or
through a U.S. office of a broker, the broker must backup withhold at a rate of
31% and report the sale to the Internal Revenue Service, unless the holder
certifies its non-U.S. status under penalties of perjury or otherwise
establishes an exemption. In the case of a non-U.S. holder that sells Class B
common stock to or through the foreign office of a U.S. broker, or a foreign
broker with certain types of relationships to the United States, the broker
must report the sale to the Internal Revenue Service (but not backup withhold)
unless the broker has documentary evidence in its files that the seller is a
non-U.S. holder or certain other conditions are met, or the holder otherwise
establishes an exemption. A non-U.S. holder will generally not be subject to
information reporting or backup withholding if such non-U.S. holder sells the
Class B common stock to or through a foreign office of a non-U.S. broker.

      Any amount withheld under the backup withholding rules from a payment to
a holder is allowable as a credit against the holder's U.S. federal income tax,
which may entitle the holder to a refund, provided that the holder furnishes
the required information to the Internal Revenue Service. In addition, certain
penalties may be imposed by the Internal Revenue Service on a holder who is
required to supply information but does not do so in the proper manner.

      The final regulations eliminate the general, current legal presumption
that dividends paid to an address in a foreign country are paid to a resident
of that country. The final regulations impose certain certification and
documentation requirements on non-U.S. holders claiming the benefit, under a
tax treaty, of a reduced withholding rate on dividends.

      Prospective purchasers of the Class B common stock are urged to consult
their own tax advisors as to the effect, if any, of the final regulations on
their purchase, ownership and disposition of the Class B common stock.

</TABLE>

      In the purchase agreement, the underwriters have agreed, subject to the
terms and conditions set forth in the agreement, to purchase all of the shares
of Class B common stock being sold pursuant to the agreement if any of the
shares of Class B common stock being sold under the agreement are purchased. If
an underwriter defaults, the purchase agreement provides that, in specified
circumstances, the purchase commitments of the nondefaulting underwriters may
be increased or the purchase agreement may be terminated.

      We and the selling stockholders have agreed to indemnify the underwriters
against liabilities under the securities laws, or to contribute to payments the
underwriters may be required to make in respect of those liabilities.

      The shares of Class B common stock are being offered by the underwriters,
subject to prior sale, when, as and if issued to and accepted by them, subject
to approval of certain legal matters by counsel for the underwriters and
certain other conditions. The underwriters reserve the right to withdraw,
cancel or modify such offer and to reject orders in whole or in part.

COMMISSIONS AND DISCOUNTS

      The representatives have advised us that they propose initially to offer
the shares of Class B common stock to the public at the initial public offering
price set forth on the cover page of this prospectus, and to certain dealers at
that price less a concession not in excess of $    per share of Class B common
stock. The underwriters may allow, and those dealers may reallow, a discount
not in excess of $    per share of Class B common stock to certain other
dealers. After the initial public offering, the public offering price,
concession and discount may change.

      The following table shows the per share and total public offering price,
underwriting discount to be paid by us and the selling stockholders to the
underwriters and the proceeds before expenses to us and the selling
stockholders. This information is presented assuming either no exercise or full
exercise by the underwriters of their over-allotment option with respect to the
selling stockholders' shares.

      The expenses of the offering (exclusive of the underwriting discount and
commissions) are estimated at $       . The underwriters have agreed to
reimburse us for up to $2.75 million of our expenses incurred in connection
with this offering.

OVER-ALLOTMENT OPTION

      The selling stockholders have granted an option to the underwriters,
exercisable for 30 days after the date of this prospectus, to purchase up to
        additional shares of Class B common stock at the public offering price
set forth on the cover page of this prospectus, less the underwriting discount.
The underwriters may exercise this option solely to cover over-allotments, if
any, made on the sale of the Class B common stock being offered. To the extent
that the underwriters exercise this option, each underwriter will be obligated,
subject to certain conditions, to purchase a number of additional shares of
Class B common stock proportionate to that underwriter's initial amount
reflected in the above table.

RESERVED SHARES

      At our request, the underwriters have reserved for sale, at the initial
public offering price up to         shares, or five percent, of the shares
offered, to be sold to persons designated by us. The number of shares of Class
B common stock available for sale to the general public will be reduced to the
extent those persons purchase reserved shares. Any reserved shares which are
not orally confirmed for purchase within one day of the pricing of this
offering will be offered by the underwriters to the general public on the same
terms as the other shares offered in this prospectus.

NO SALES OF SIMILAR SECURITIES

      For a period of 180 days after the date of this prospectus, we, our
officers, directors and certain stockholders, have agreed not to, directly or
indirectly, subject to certain exceptions, without the prior written consent of
Merrill Lynch, Pierce, Fenner & Smith Incorporated on behalf of the several
underwriters:

    .  offer, pledge, sell, dispose of or transfer any shares of common
       stock or securities convertible into common stock; or

    .  enter into any agreement that transfers any part of the economic
       consequence of ownership of the common stock.

LISTING ON THE NEW YORK STOCK EXCHANGE AND THE FRANKFURT STOCK EXCHANGE

      In the United States, our Class B common stock will trade on the New York
Stock Exchange under the symbol "       ." In Europe, our Class B common stock
will trade on the Frankfurt Stock Exchange under the symbol "       ."

      Before this offering, there has been no public market for our Class B
common stock. The initial public offering price has been determined through
negotiations between us and the representatives. The principal factors
considered in determining the initial public offering price, in addition to
prevailing market conditions, were the valuation multiples of publicly-traded
companies that the representatives believe to be comparable to us, some of our
financial information, the history of, and the prospects for, our company and
the industry in which we compete, and an assessment of our management, its past
and present operations, the prospects for, and timing of, our future revenues,
the present state of our development and the above factors in relation to
market values and various value measures of other companies engaged in
activities similar to ours. We cannot assure you that an active trading market
will develop for our Class B common stock or that our Class B common stock will
trade in the public market subsequent to this offering at or above the initial
public offering price.

      The underwriters do not expect sales of the Class B common stock to be
made to any accounts over which they exercise discretionary authority to exceed
five percent of the number of shares being offered in this offering.

                                       77

PRICE STABILIZATION, SHORT POSITIONS AND PENALTY BIDS

      Until the distribution of the Class B common stock is completed, rules of
the SEC may limit the ability of the underwriters and some selling group
members to bid for and purchase our Class B common stock. As an exception to
these rules, the representatives are permitted to engage in transactions that
stabilize the price of our Class B common stock. These transactions consist of
bids or purchases for the purpose of pegging, fixing or maintaining the price
of our Class B common stock.

      If the underwriters create a short position in our Class B common stock
in connection with the offering, that is, if they sell more shares of our Class
B common stock than are set forth on the cover page of this prospectus, the
representatives may reduce that short position by purchasing our Class B common
stock in the open market. The representatives may also elect to reduce any
short position by exercising all or part of the over-allotment option described
above.

      The representatives may also impose a penalty bid on our underwriters and
selling group members. This means that if the representatives purchase shares
of our Class B common stock in the open market to reduce the underwriters'
short position or to stabilize the price of our Class B common stock, they may
reclaim the amount of the selling concession from the underwriters and selling
group members who sold those shares.

      In general, purchases of a security for the purpose of stabilization or
to reduce a short position could cause the price of the security to be higher
than it might be in the absence of such purchases. The imposition of a penalty
bid might also have an effect on the price of our Class B common stock to the
extent that it discourages resales of our Class B common stock.

      Neither we nor any of the underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of our Class B common stock. In addition,
neither we nor any of the underwriters makes any representation that the
representatives will engage in these transactions or that these transactions,
once commenced, will not be discontinued.

OTHER RELATIONSHIPS

      Some of the underwriters and their affiliates have from time to time
provided, and may in the future provide, investment banking and general
financing and banking services to us and our affiliates. Merrill Lynch Capital
Corporation acted as the lender for our $50.0 million bridge loan facility.
Merrill Lynch & Co. acted as Lead Arranger and Syndication Agent to underwrite
and syndicate our $250.0 million senior secured credit facility for which it
received customary compensation. Merrill Lynch Capital Corporation and Warburg
Dillon Read LLC are also lenders under the credit facility. Warburg Dillon Read
LLC acted as our financial advisor in connection with the AUCS transactions and
received customary fees.

                          INDEPENDENT AUDITORS' REPORT

To the Stockholders and Board of Directors of
 Infonet Services Corporation
El Segundo, California:

      We have audited the accompanying consolidated balance sheets of Infonet
Services Corporation and its subsidiaries (the "Company") as of March 31, 1998
and 1999, and the related consolidated statements of operations and
comprehensive income (loss), stockholders' equity, and cash flows for each of
the three years in the period ended March 31, 1999. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

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

      In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of the Company as of March 31,
1998 and 1999, and the results of its operations and its cash flows for each of
the three years in the period ended March 31, 1999 in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                   YEARS ENDED MARCH 31, 1997, 1998 AND 1999

1. GENERAL INFORMATION

      DESCRIPTION OF BUSINESS--Infonet Services Corporation ("Infonet" or the
"Company") provides cross-border managed data communications services to
multinational corporations worldwide. Infonet's stockholders include six of the
world's major telecommunication companies. Infonet provides services directly
through country representatives and indirectly through major international
telecommunications carrriers and value-added resellers.

      FISCAL YEAR--The Company's fiscal year is the 52- or 53-week period
ending on the Friday nearest to March 31. For simplicity of presentation, the
Company has described the 52-week period ended March 28, 1997, the 53-week
period ended April 3, 1998 and the 52-week period ended April 2, 1999 as the
years ended March 31, 1997, 1998 and 1999, respectively, and the 13-week
periods ended July 3, 1998 and July 2, 1999 as the three months ended June 30,
1998 and 1999, respectively.

      UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS--The
condensed consolidated financial statements as of June 30, 1999 and for the
three months ended June 30, 1998 and 1999 are unaudited. In the opinion of
management, the unaudited financial statements have been prepared on the same
basis as the audited financial statements and include all adjustments,
consisting of normal recurring adjustments, necessary for a fair presentation
of the financial position and the results of operations as of such date and for
such periods. Results of interim periods are not necessarily indicative of the
results to be expected for the entire fiscal year.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      PRINCIPLES OF CONSOLIDATION--All majority-owned subsidiaries and
subsidiaries where the Company exercises economic control are included in the
consolidated financial statements. All significant intercompany accounts and
transactions have been eliminated. The Company's investments in 20% to 50%
owned companies in which it has the ability to exercise significant influence
over operating and financial policies of the investee are accounted for using
the equity method.

      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. As with any estimates, actual results could differ
from those estimates.

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

      SHORT-TERM INVESTMENTS--Short-term investments are classified as
"available for sale" and are carried at market value.

      FAIR VALUE OF FINANCIAL INSTRUMENTS--The carrying amounts of cash and
cash equivalents, short-term investments, accounts receivable, and accounts
payable approximate fair value because of the short-term maturities of these
instruments. The carrying amount of the long-term note payable approximates
fair value since the fixed rate charged on the note approximates the current
market rate.

                                      F-7

                 INFONET SERVICES CORPORATION AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                   YEARS ENDED MARCH 31, 1997, 1998 AND 1999


      CONCENTRATION OF CREDIT RISK--The Company's financial instruments that
are exposed to concentration of credit risk consist primarily of its cash
equivalents, short-term investments, and accounts receivable. The Company
restricts investments in cash equivalents and short-term investments to
financial institutions with high credit standing. Credit risk on accounts
receivable is minimized as a result of the large and diverse nature of the
Company's worldwide customer base. The Company performs ongoing credit
evaluations of its customers' financial condition and maintains allowances for
potential credit losses.

      REVENUE RECOGNITION--The Company records revenues for communications,
data processing, and management services when the services are provided. Such
services are provided under client contracts which generally have a term of 1
to 3 years. Amounts for services billed in advance of the service period and
cash received in advance of revenues earned are recorded as advance billings
and recognized as revenue when earned. Approximately 14%, 8% and 0% of revenues
for fiscal year 1997, 1998 and 1999, respectively, is derived from long-term
fixed priced contracts with various U.S. government agencies. These long-term
contracts are accounted for utilizing the percentage of completion method of
accounting (cost-to-cost and output methods). An allowance for customer credits
is accrued concurrently with the recognition of revenue.

      DEPRECIATION AND AMORTIZATION--The cost of property, equipment and
communication lines, less applicable estimated residual values, is depreciated
over their useful lives, on the straight-line method, from the date the
specific asset is complete, installed, and ready for normal use, as follows:

<TABLE>
     <S>                                <C>
     Communication, computer and re-
      lated equipment.................. 3 to 5 years
     Communication lines............... 10 years
     Buildings......................... 40 years
     Leasehold improvements............ Shorter of lease term or useful lives
     Furniture and other equipment..... 5 to 10 years
</TABLE>

      GOODWILL AND OTHER INTANGIBLE ASSETS--Goodwill arising from the
acquisition of businesses is amortized on a straight-line basis over a period
of 20 years. Intangible assets include customer base and trademarks, which are
amortized over 10 years on a straight-line basis.

      IMPAIRMENT OF LONG-LIVED ASSETS--The Company evaluates long-lived assets
for impairment whenever events or changes in circumstances indicate that the
carrying value of an asset may no longer be recoverable. If the estimated
future cash flows (undiscounted and without interest charges) from the use of
an asset are less than the carrying value, a write-down would be recorded to
reduce the related asset to its estimated fair value. During fiscal 1998, the
Company recorded an impairment charge on certain equipment in the amount of
$5.2 million, in view of its technological obsolescence.

      INCOME TAXES--Deferred income tax assets and liabilities are computed
annually for differences between the financial statement and income tax bases
of assets and liabilities. Such deferred income tax asset and liability
computations are based on enacted tax laws and rates applicable to periods in
which the differences are expected to reverse. If necessary, a valuation
allowance is established to reduce deferred income tax assets to the amount
expected to be realized. U.S. income taxes have not been provided for the
undistributed earnings of the Company's foreign subsidiaries, since such
earnings are intended to be permanently reinvested in the operations of those
subsidiaries. At March 31, 1999 the cumulative undistributed earnings of the
Company's foreign subsidiaries was approximately $17,154,000 and unrecognized
deferred taxes were not material.

                   YEARS ENDED MARCH 31, 1997, 1998 AND 1999


      FOREIGN CURRENCY TRANSLATION--For foreign operations, the balance sheet
accounts are translated at the year-end exchange rate, and income statement
items are translated at the average exchange rate for the year. Resulting
translation adjustments are recorded as a separate component of other
comprehensive income. Assets and liabilities denominated in foreign currencies
are remeasured at the balance sheet date. Resulting exchange rate gains or
losses are included as a component of current period earnings. Exchange gains
and losses are not material in amount in any period.

      NEW ACCOUNTING PRONOUNCEMENTS--The Financial Accounting Standards Board
("FASB") has issued Statement of Financial Accounting Standards ("SFAS") No.
133, "Accounting for Derivative Instruments and Hedging Activities," which
establishes new standards for reporting derivative and hedging information.
SFAS 133 is effective for periods beginning after June 15, 2000. Management has
not completed its assessment of the impact of the adoption of SFAS No. 133 on
the Company's financial position or results of operations.

      RECLASSIFICATIONS--Certain prior year amounts have been reclassified to
conform to current year presentation.

      Although realization is not assured, management believes that it is more
likely than not that all deferred income tax assets at March 31, 1999 will be
realized. If, however, estimates of future taxable income were to materially
decline, the carrying value of deferred income tax assets could be reduced.

      Rental expense under noncancelable operating leases for the use of real
estate and equipment amounted to approximately $8,480,000, $8,800,000 and
$8,886,000 in 1997, 1998 and 1999, respectively.

      The Company leases certain communication lines and related bandwidth for
its backbone network under short-term arrangements which are cancelable by
either party.

      Capital leases pertain to amounts due under leases for the use of
communications and related equipment. The net book value at March 31, 1998 and
1999 of the related assets included in property, equipment and communication
lines was $219,000 and $6,733,000, respectively.

      During November 1999, the Company's existing headquarters facility lease
with Computer Sciences Corporation will expire and the Company is currently
continuing to lease the facility on a month-to-month basis. The Company has
entered into a 12-year lease agreement for a new facility, which will commence
upon completion of construction. The expected date of the relocation to the new
facility is November 1999. The minimum lease payments disclosure above does not
reflect the new facility lease because the rent has not yet been determined.
However, the annual base rent is expected to approximate $3.0 million with
increases every 30 months. The first increase will be 7%, with additional
increases based on a formula using the Consumer Price Index. The terms of the
lease agreement require the Company to maintain certain financial covenants.
Additionally, the lease agreement includes an option to purchase the building
within 90 days of the commencement of the lease. The Company has not determined
whether it will exercise that option.

      LITIGATION--During the normal course of business, the Company may be
subject to litigation involving various business matters. Management believes
that an adverse outcome of any such known matters would not have a material
adverse impact on the Company.

8. LONG-TERM OBLIGATIONS

      The Company has a $10.0 million credit agreement (the "Credit Agreement")
with a bank, expiring in July 1999, under which no borrowings were outstanding
as of March 31, 1998 or 1999. Borrowings under the Credit Agreement bear
interest, at the Company's option, at either the prime rate or London Interbank
Offering Rate ("LIBOR") plus 1.25%. The terms of the Credit Agreement contain,
among other provisions, requirements for maintaining defined levels of
profitability, tangible net worth, and various financial ratios. The amount of
credit available under the Credit Agreement is reduced by the amount of
outstanding letters of credit, which totaled $2.5 million at March 31, 1999.
Thus, total available credit under the line was $7.5 million at March 31, 1999.

      In December 1998, the Company obtained a $9.5 million note payable with
the same bank. This five-year note accrues interest at a fixed rate of 7.36%
and is collateralized by the leased communication lines.

      Maturities of long-term debt for the next five years are as follows (in

9. EMPLOYEE BENEFIT PLANS

      PENSIONS--The Infonet Pension Plan (the "Plan") is a contributory defined
benefit pension plan in which substantially all domestic employees are eligible
to participate. The benefits for the Plan are based on years of participation
and the employee's compensation over the entire period of participation in the
Plan. In addition, the Company has a Supplemental Executive Retirement Plan
(the "SERP"), which is a nonqualified, noncontributory pension plan. The SERP
is a defined benefit retirement plan for designated key officers and executives
and provides for benefits based on years of service, age of participant, and
the participant's average compensation during his or her final period of
employment under the SERP.

      The following tables provide a reconciliation of the changes in the
plans' benefit obligations and fair value of assets over the two years, and a
statement of the funded status as of each year-end (dollars in thousands):

      The rate of compensation increase shown is for the qualified pension
plan. For the nonqualified pension plan, compensation is assumed to increase at
a 4% annual rate.

      For measurement purposes, an 8% annual rate of increase in the per capita
cost of covered health care benefits was assumed in 1999. The rate was assumed
to decrease gradually to 5% for 2002 and remain at that level thereafter.

      Net periodic benefit cost for pension plans include the following
components (in thousands):

      At March 31, 1998 and 1999, the Company earmarked a total of $4.7 million
and $6.9 million, respectively, and placed these amounts in a rabbi trust to
satisfy future SERP liabilities. These assets are accounted for as "held to
maturity" and included in other assets in the accompanying consolidated
financial statements.

      Employees outside the United States are generally enrolled in pension
plans in the country of domicile. These plans are not considered to be
significant individually or in the aggregate to the Company's financial
statements. The pension liabilities and their related costs are computed in
accordance with the laws of the individual countries and appropriate actuarial
practices.

10. STOCK INCENTIVE AND DEFERRED COMPENSATION PLANS

      During 1999, the Company's Board of Directors adopted the 1998 Employee
Stock Purchase Plan (the "Purchase Plan"), 1998 Stock Appreciation Rights Plan
(the "SARs Plan"), and 1998 Stock Option Plan (the "Option Plan"). The Company
has elected to account for stock-based compensation in accordance with the
provisions of Accounting Principles Board ("APB") Opinion No. 25, "Accounting
for Stock Issued to Employees." SFAS No. 123, "Accounting for Stock-Based
Compensation," encourages a fair value-based method of accounting for stock-
based compensation. As permitted by SFAS No. 123, the Company adopted its
disclosure-only requirements.

                   YEARS ENDED MARCH 31, 1997, 1998 AND 1999


      Under the Purchase Plan, the Company is authorized to issue up to 600
shares of its newly authorized Class C common stock, $0.01 par value ("Class C
Stock") to 35 participants designated by the Committee which administers the
Purchase Plan. The Purchase Plan is a book value plan whereby participants may
purchase shares of the Company's stock at book value at the date of grant, as
calculated in accordance with the Purchase Plan. The Purchase Plan provides
that book value is determined using a formula based on a multiple of the
Company's consolidated revenue. The Purchase Plan also provides that the
Company has a call right to repurchase the shares from stockholders under the
Purchase Plan who leave the Company's employ, or on or after March 15, 2003,
provided that the stock is not publicly traded. The stockholders under the
Purchase Plan also have a right to put the shares purchased under the Purchase
Plan to the Company, which then has to repurchase the shares at its book value
as of that date, provided that the stock is not publicly traded. During 1999,
the Company granted purchase rights with respect to approximately 318 shares at
$25,000 per share.

      Pursuant to the Company's SARs Plan, the maximum number of SARs that may
be offered is 50. The stock referred to in the SARs Plan is the newly
authorized Class C Stock. The SARs vest at 25% per year over four years with
the first quartile vesting on January 1, 2001. The SARs Plan terminates October
20, 2004 or earlier if certain conditions of the SARs Plan have been fully met.
During fiscal 1999, the Company granted approximately 40 SARs which are indexed
to the Company's Class C common stock at a base price of $25,000 per share.

      Under the Option Plan, the Company is authorized to issue options to
purchase up to 300 shares of its Class C Stock. Options granted under the
Option Plan vest ratably over five years. All options must be exercised within
ten years from the date of original grant. The Option Plan is a book value plan
whereby participants are granted options to purchase shares of the Company's
stock at book value, as determined at the date of grant and as calculated in
accordance with the Option Plan. The Option Plan provides that book value is
determined using a formula based on a multiple of the Company's consolidated
revenue. The Option Plan also provides that the Company has a call right to
repurchase the shares from stockholders under the Option Plan who leave the
Company's employ, or on or after March 15, 2003, provided that the stock is not
publicly traded. The stockholders under the Option Plan also have a right to
put the shares purchased under the Option Plan to the Company, which then has
to repurchase the shares at its book value as of that date, provided that the
stock is not publicly traded. During 1999, no options were granted.

      The Company has a nonqualified deferred income plan (the "IDIP") for
employees earning over a prescribed amount. Participants may defer receipt of
compensation, which is held by the Company in trust and is invested in
accordance with the participants' directions. As of March 31, 1998 and 1999,
the trust assets held by the Company aggregated $8,829,000 and $9,813,000,
respectively; the vested portion of trust assets aggregated $6,875,000 and
$8,528,000, respectively. These assets are accounted for as trading securities
and included in other assets in the accompanying financial statements.

      In 1995, the Company created an agreement with the participants of the
Infonet Phantom Stock Option Plan (the "Phantom Stock Plan") whereby the
participants could elect either a cash or deferral option for the vested value
of grants under the Phantom Stock Plan at the end of 1994, effectively
terminating the Phantom Stock Plan. Participants who elected the deferral
option are eligible to receive additional amounts through 1999, based on the
Company's achieving revenue and profit goals and the individuals' continued
employment. Under this arrangement, the expense in 1997, 1998 and 1999 was
$900,000, $803,000 and $830,000, respectively. Participants can elect to have
their annual vested portion contributed to their individual account as part of
the IDIP.

13. ACQUISITIONS AND DIVESTITURES

      On January 3, 1997 the Company acquired 95% of the capital stock of
Interpac Belgium S.A. The purchase price was approximately $3,120,000 and the
resulting goodwill recorded was approximately $103,000. Prior to this date the
Company owned a 5% interest in Interpac Belgium S.A. which was accounted for
on the cost basis. In March 1997 the Company acquired an additional 36%
interest in its Luxembourg subsidiary for $330,000 bringing its ownership to
51%.

      These acquisitions were accounted for under the purchase method. The
excess of the purchase cost of the acquisitions over the fair value of the net
assets acquired was recorded as goodwill which is being amortized on a
straight-line basis over 20 years.

      During fiscal 1997 the Company sold its remaining interest in a foreign
affiliate for a pretax gain of $1,030,000 and Interpac Belgium sold its
Internet business to one of its former shareholders for a net pretax gain of
$2,700,000. These pretax gains are recorded in other income in the statement of
operations and comprehensive income (loss).

      In October 1997, the Company sold the net assets of its subsidiary,
Government Systems, Inc. ("GSI"), to a third party for $21.0 million in cash
and received $5.5 million as a working capital adjustment to pay down GSI loans
prior to transfer of the net assets sold. The sale resulted in a pretax gain of
$3.7 million, which is recorded in other income in the statement of operations
and comprehensive income (loss). GSI's results from operations included in the
1998 consolidated statements of operations and comprehensive income (loss) were
revenues of $32.5 million and income before income taxes of $4.0 million.
Additionally, the Company sold its government accounts to the same third party
and entered into an agreement allowing the third party to operate as a country
representative for a total of $7.0 million in cash.

14. EARNINGS PER SHARE

      As of March 31, 1997 and 1998, there were no forms of potential common
stock issued by the Company. The Company's outstanding purchase rights
represent the only form of potential common stock at March 31, 1999. All of
these potential common shares were excluded from the computation of diluted
earnings per share ("EPS") because their inclusion would have had an
antidilutive effect on EPS.

      Unaudited: As of June 30, 1998, there were no forms of potential common
stock issued by the Company. The Company's outstanding stock options represent
the only form of potential common stock at June 30, 1999. All of these
potential common shares were excluded from the computation of diluted EPS
because their inclusion would have been antidilutive.

15. SEGMENT INFORMATION

      The Company conducts business in two operating segments: country
representatives or Direct Sales Channels ("Direct") and Alternate Sales
Channels ("Alternate"). Both these segments generate revenues from providing
customers with a complete global networking solution.

      The Company has organized its operating segments around differences in
distribution channels used to deliver its services to customers. These segments
are managed and evaluated separately because each segment possesses different
economic characteristics requiring different marketing strategies.

      The accounting policies adopted for each segment are the same as those
described in the summary of significant accounting policies. The Company's
management evaluates performance based on operating contribution, where segment
revenues are reduced by those costs that are allocable to the segments. Costs
relating to operating the Company's core network, and non-allocable general,
administrative, marketing and overhead costs, including income tax expense, are
not charged to the segments. Accordingly, neither assets related to the core
network, nor their associated depreciation expense are allocated to the
segments.

      The Company accounts for intersegment transactions on the same terms and
conditions as if the transactions were with third parties.

16. SUBSEQUENT EVENTS

      During April 1999, approximately 316 of the approximately 318 rights to
purchase shares of Class C Stock granted under the Purchase Plan were exercised
by employees and the remaining rights expired unexercised. Of the total shares
issued, approximately 314 shares were purchased with full recourse notes in the
amount of $7,856,000, by the employees to the Company. Approximately 2 shares
issued were purchased with cash. The notes bear interest at 5% per year and are
payable on January 1, 2002 (the "Maturity Date"); provided however, that if the
shares of common stock, or a class of securities into which such shares are
convertible, are sold in an IPO after January 1, 2000, but before the Maturity
Date, the Maturity Date shall be extended by the period of time, if any,
between January 1, 2000 and the date of such IPO. During April 1999, the
Company granted options to acquire 124 shares of Class C Stock with an exercise
price of $25,000 per share. These options vest ratably over five years.

      In May 1999, the Company obtained a $50.0 million bridge loan facility
(the "Bridge Loan") from Merrill Lynch. The Bridge Loan bears interest at LIBOR
plus 2.5% and expires in November 1999. The Company used a portion of the
proceeds from the Bridge Loan to repay the existing $10.0 million line of
credit.

UNAUDITED

      Subsequent to June 14, 1999, the Company amended the SARs Plan by
eliminating the limit on the maximum number of SARs that may be offered and the
termination date of October 20, 2004. The Company also issued approximately 13
additional SARs under the SARs Plan which are indexed to the Company's Class C
common stock at a base price of $25,000 per share. As of June 30, 1999, there
were approximately 53 SARs outstanding.

      During June 1999, the Company entered into an agreement for the long-term
right of use of capacity in a fiberoptic submarine cable system (the "Right of
Use"). The Right of Use acquired by the Company is comprised of three units of
capacity at a total commitment of $45.0 million. The first unit of capacity was

activated in June 1999 for a payment of $18.0 million. The second installment
of $12.0 million is due on the earlier of the activation of the second unit of
capacity or June 30, 2000. The third installment of $15.0 million is due on the
earlier of the activation of the third unit of capacity or June 30, 2000. The
Company intends to refinance the second and third installment obligations
through drawdowns on the Senior Secured Credit Facility described below. The
Company has the right to have the capacity activated at any time after the date
of the agreement and has the right to use the capacity to the end of the cable
system's design life which is expected to occur in 2022. The Right of Use was
recorded as communication lines.

      On August 17, 1999, the Company entered into a new credit agreement (the
"New Credit Agreement") with a syndicate of lenders to provide credit
facilities to the Company in an aggregate amount of $250.0 million (the "Senior
Secured Credit Facility"). The Senior Secured Credit Facility consists of two
term loan borrowing facilities, in the amount of $100.0 million (the "Delayed
Draw Term Loan") and $50.0 million (the "Tranche B Term Loan"), respectively,
and a revolving credit borrowing facility in the amount of $100.0 million (the
"Revolving Credit Facility"). The Tranche B Term Loan was used to pay down in
full all amounts outstanding on August 20, 1999 under the Bridge Loan and the
$9.5 million note payable. The Tranche B Term Loan bears interest, at the
Company's option, at the Base Rate, as defined below, plus 1.75% or the
eurodollar rate plus 2.75%, and matures in 28 consecutive unequal quarterly
installments, commencing on September 30, 1999. The Delayed Draw Term Loan is
accessible until August 20, 2000, bears interest, at the Company's option, at
the Base Rate, as defined below, plus 1.50% or the eurodollar rate plus 2.50%,
and matures in 20 consecutive unequal quarterly installments, commencing on
September 30, 2001. The Revolving Credit Facility is accessible until August
20, 2005, bears interest, at the Company's option, at the Base Rate, as defined
below, plus 1.50% or the eurodollar rate plus 2.50% (which margin will vary
after February 20, 2000, depending on the Company's leverage ratio), and
matures on August 17, 2005. The Company is also required, by February 17, 2000,
to enter into hedge agreements to provide that at least 50% of the outstanding
term loans are subject to either a fixed interest rate or interest rate
protection for a period acceptable to the administrative agent.

      The Base Rate is defined as the greatest of the Prime Rate, the Base CD
Rate plus 1.00% and the Federal Funds Effective Rate plus 0.50% in effect on a
given day. The loans under the Senior Secured Credit Facility are secured by
substantially all of the domestic tangible assets and all intangible assets of
the Company and its domestic subsidiaries, excluding certain specific assets
identified in the New Credit Agreement. Under the terms of the Senior Secured
Credit Facility the Company is required to maintain certain financial ratios
and other financial conditions, and there are restrictions imposed on certain
transactions of the Company. The Senior Secured Credit Facility also provides
for letters of credit to be available to the Company. Furthermore, the New
Credit Agreement requires the Company to pay commitment fees of between 0.50%
and 1.00% per year calculated quarterly on the average daily amount of
available credit, dependent on the amount of the aggregate principle amounts
outstanding under the Senior Secured Credit Facility. These commitment fees are
payable quarterly in arrears.

      On September 30, 1999, the Company entered into agreements with three of
its stockholders and affiliates of these stockholders which, among other
things, give the Company access to additional multinational corporate clients
currently served by the affiliates of the stockholders. In consideration of the
execution of these agreements and the receipt of $40.0 million of cash, the
Company issued 1,600 shares of the Class B common stock to these stockholders.

effect as of the date hereof, and the Registrant's Second Amended and Restated
Certificate of Incorporation to be in effect upon the closing of this offering
(collectively, the "Certificate") provides that, except to the extent
prohibited by the Delaware General Corporation Law, as amended (the "DGCL"),
the Registrant's directors shall not be personally liable to the Registrant or
its stockholders for monetary damages for any breach of fiduciary duty as
directors of the Registrant. Under the DGCL, the directors have a fiduciary
duty to the Registrant which is not eliminated by this provision of the
Certificate and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of nonmonetary relief will remain available. In
addition, each director will continue to be subject to liability under the DGCL
for breach of the director's duty of loyalty to the Registrant, for acts or
omissions which are found by a court of competent jurisdiction to be not in
good faith or involving intentional misconduct, for knowing violations of law,
for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of stock repurchases or redemptions that are
prohibited by the DGCL. This provision also does not affect the directors'
responsibilities under any other laws, such as the Federal securities laws or
state or Federal environmental laws. The Registrant has applied for liability
insurance for its officers and directors.

      Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers, provided that this
provision shall not eliminate or limit the liability of a director: (i) for any
breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) arising under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit. The DGCL provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any other
rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, a vote of stockholders or otherwise. The
Certificate eliminates the personal liability of directors to the fullest
extent permitted by Section 102(b)(7) of the DGCL and provides that the
Registrant may fully indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (whether civil, criminal, administrative or investigative)
by reason of the fact that such person is

                                      II-1
<PAGE>

or was a director or officer of the Registrant, or is or was serving at the
request of the Registrant as a director or officer of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection
with such action, suit or proceeding.

      At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Certificate. The Registrant is not aware of any
threatened litigation or proceeding that may result in a claim for such
indemnification.

Item 15. Recent Sales of Unregistered Securities

      Pursuant to Rule 701 of the Act, in April 1999, we sold 315.87 shares of
our Class C common stock to our key employees pursuant to our 1998 Stock
Purchase Plan. In accordance with the provisions of the Stock Purchase Plan,
some employees purchased their shares for cash and other employees received
their shares in exchange for a secured, recourse promissory note held by us.
Part of the security for the promissory notes are the shares sold to each
purchaser. Each share was sold for $25,000, which price was set by the pricing
formula at the time of the sales. Immediately prior to the closing of this
offering, our Class C common stock will be converted to Class B common stock.

      During the three months ended September 30, 1999, in exchange for the
right to market our services to their clients and $40.0 million in cash, we
issued an aggregate of 1,600 shares of our Class B common stock to KPN,
Swisscom and Telia in reliance on Rule 506 of Regulation D under the Act.

      In reliance on Rule 506 of Regulation D of the Act, in November 1996, we
sold an aggregate of 967.13 shares of our Class B common stock to KDD, KPN,
Swisscom, Telefonica and Telia for approximately $19.0 million. Part of the
proceeds of the sale were used to repurchase our Class A common stock from
Belgacom S.A. As a result of this transaction, Belgacom was no longer one of
our stockholders.

Item 17. Undertakings

      The undersigned Registrant hereby undertakes to provide to the
Underwriter at the closing specified in the Purchase Agreement, certificates in
such denominations and registered in such names as required by the Underwriter
to permit prompt delivery to each purchaser.

      Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the "Act") may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the SEC such
indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication
of such issue.

      The undersigned Registrant hereby undertakes that:

    (1) For purposes of determining any liability under the Act, the
        information omitted from the form of prospectus filed as part of
        this registration statement in reliance upon Rule 430A and contained
        in a form of prospectus filed by the registrant pursuant to Rule 424
        (b)(1) or (4), or 497(h) under the Act, shall be deemed to be part
        of this registration statement as of the time it was declared
        effective.

    (2) For the purpose of determining any liability under the Act, each
        post-effective amendment that contains a form of prospectus shall be
        deemed to be a new registration statement relating to the securities
        offered therein, and this offering of such securities at that time
        shall be deemed to be the initial bona fide offering thereof.

              --------------------------
exclusive authority to operate, manage and administer the Plan in accordance
with its terms and conditions. Notwithstanding the foregoing, in its absolute
discretion, the Board may at any time and from time to time exercise any and all
rights, duties and responsibilities of the Committee under the Plan, including,
but not limited to, establishing procedures to be followed by the Committee,
except with respect to matters which under any applicable law, regulation or
rule, are required to be determined in the sole discretion of the Committee. If
and to the extent that no Committee exists which has the authority to administer
the Plan, the functions of the Committee shall be exercised by the Board.

          (b) The Committee shall be appointed from time to time by the Board
and the Committee shall consist of not less than two (2) members.  Committee
members may be removed by the Board at any time either with or without cause,
and such members may resign at any time by delivering notice thereof to the
Board.  Any vacancy on the Committee, whether due to action of the Board or any
other reason, shall be filled by the Board.

          (c) The Committee shall have full authority to grant, pursuant to the
terms of the Plan, Options to those individuals who are eligible to receive
Options under the Plan.  In particular, the Committee shall have discretionary
authority to, in accordance with the terms of the Plan:  determine eligibility
for participation in the Plan; select, from time to time, from among those
eligible, the employees, directors and consultants to whom Options shall be
granted under the Plan, which selection may be based upon information furnished
to the Committee by the Company's management; determine whether an Option shall
take the form of an ISO or Option other than an ISO; determine the number of
shares of Stock to be included in any Option or to which any Option shall
otherwise relate and the periods for which Options will be outstanding;
establish and administer any terms, conditions, performance goals, performance
targets, restrictions, limitations, forfeiture, vesting or exercise schedule,
and other provisions of or relating to any Options; to the extent permitted
under the applicable Agreement, grant waivers

                                      -3-
<PAGE>

of terms, conditions, restrictions and limitations under the Plan or applicable
to any Option, or accelerate the vesting or exercisability of any Option; amend
or adjust the terms and conditions of any outstanding Option and/or adjust the
number and/or class of shares of Stock subject to any outstanding Option; at any
time and from time to time after the granting of an Option, specify such
additional terms, conditions and restrictions with respect to any such Option as
may be deemed necessary or appropriate to ensure compliance with any and all
applicable laws or rules, including, but not limited to, terms, restrictions and
conditions for compliance with applicable securities laws, regarding an
Optionee's exercise of Options by tendering shares of Stock or under a "cashless
exercise" program established by the Committee, and methods of withholding or
providing for the payment of required taxes; offer to buy out an Option
previously granted, based on such terms and conditions as the Committee shall
establish and communicate to the Optionee at the time such offer is made; and,
to the extent permitted under the applicable Agreement, permit the transfer of
an Option or the exercise of an Option by one other than the Optionee who
received the grant of such Option (other than any such a transfer or exercise
which would cause any ISO to fail to qualify as an "incentive stock option"
under Section 422 of the Code).

          (d) The Committee shall have all authority that may be necessary or
helpful to enable it to discharge its responsibilities with respect to the Plan.
Without limiting the generality of the foregoing sentence or paragraph (a) of
this Section 3, and in addition to the powers otherwise expressly designated to
the Committee in the Plan, the Committee shall have the exclusive right and
discretionary authority to  interpret the Plan and the Agreements; construe any
ambiguous provision of the Plan and/or the Agreements and decide all questions
concerning eligibility for and the amount of Options granted under the Plan.
The Committee may establish, amend, waive and/or rescind rules and regulations
and administrative guidelines for carrying out the Plan and may correct any
errors, supply any omissions or reconcile any inconsistencies in the Plan and/or
any Agreement or any other instrument relating to any Options.  The Committee
shall have the authority to adopt such procedures and subplans and grant Options
on such terms and conditions as the Committee determines necessary or
appropriate to permit participation in the Plan by individuals otherwise
eligible to so participate who are foreign nationals or employed outside of the
United States, or otherwise to conform to applicable requirements or practices
of jurisdictions outside of the United States; and take any and all such other
actions it deems necessary or advisable for the proper operation and/or
administration of the Plan.  The Committee shall have full discretionary
authority in all matters related to the discharge of its responsibilities and
the exercise of its authority under the Plan.  Decisions and actions by the
Committee with respect to the Plan and any Agreement shall be final, conclusive
and binding on all persons having or claiming to have any right or interest in
or under the Plan and/or any Agreement.

          (e) Each Option shall be evidenced by an Agreement, which shall be
executed by the Company and the Optionee to whom such Option has been granted,
unless the Agreement provides otherwise; however, two or more Options to a
single Optionee may be combined in a single Agreement.  An Agreement shall not
be a precondition to the granting of an Option; however, no person shall have
any rights under any Option unless and until the Optionee to whom the Option
shall have been granted (i) shall have executed and delivered to the

                                      -4-
<PAGE>

Company an Agreement or other instrument evidencing the Option, unless such
Agreement provides otherwise, and (ii) has otherwise complied with the
applicable terms and conditions of the Option. The Committee shall prescribe the
form of all Agreements, and, subject to the terms and conditions of the Plan,
shall determine the content of all Agreements. Any Agreement may be supplemented
or amended in writing from time to time as approved by the Committee; provided
that the terms and conditions of any such Agreement as supplemented or amended
are not inconsistent with the provisions of the Plan.

          (f) A majority of the members of the entire Committee shall constitute
a quorum and the actions of a majority of the members of the Committee in
attendance at a meeting at which a quorum is present, or actions by a written
instrument signed by all members of the Committee, shall be the actions of the
Committee.

          (g) The Committee may consult with counsel who may be counsel to the
Company. The Committee may employ such other attorneys or consultants,
accountants, appraisers, brokers or other persons as it deems necessary or
appropriate. In accordance with Section 12, the Committee shall not incur any
liability for any action taken in good faith in reliance upon the advice of such
counsel or such other persons.

          (h) In serving on the Committee, the members thereof shall be entitled
to indemnification as directors of the Company, and to any limitation of
liability and reimbursement as directors with respect to their services as
members of the Committee.

          (i) Except to the extent prohibited by applicable law or the
applicable rules of a stock exchange, the Committee may, in its discretion,
allocate all or any portion of its responsibilities and powers under this
Section 3 to any one or more of its members and/or delegate all or any part of
its responsibilities and powers under this Section 3 to any person or persons
selected by it; provided, however, the Committee may not delegate its authority
to correct errors, omissions or inconsistencies in the Plan.  Any such authority
delegated or allocated by the Committee under this paragraph (i) of Section 3
shall be exercised in accordance with the terms and conditions of the Plan and
any rules, regulations or administrative guidelines that may from time to time
be established by the Committee, and any such allocation or delegation may be
revoked by the Committee at any time.

          4.  Shares of Stock Subject to the Plan.  (a)  The shares of stock
              -----------------------------------
subject to Options granted under the Plan shall be shares of Stock.  Such shares
of Stock subject to the Plan may be either authorized and unissued shares (which
will not be subject to preemptive rights) or previously issued shares acquired
by the Company or any Subsidiary.  The total number of shares of Stock that may
be delivered pursuant to Options granted under the Plan is 300.

          (b) Notwithstanding any of the foregoing limitations set forth in this
Section 4, the numbers of shares of Stock specified in this Section 4 shall be
adjusted as provided in Section 10.

                                      -5-
<PAGE>

          (c) Any shares of Stock subject to an Option which for any reason
expires or is terminated without having been fully exercised may again be
granted pursuant to an Option under the Plan, subject to the limitations of this
Section 4.

          (d) Any shares of Stock delivered under the Plan in assumption or
substitution of outstanding stock options, or obligations to grant future stock
options, under plans or arrangements of an entity other than the Company or an
Affiliate in connection with the Company or an Affiliate acquiring such another
entity, or an interest in such an entity, or a transaction otherwise described
in Section 6(i), shall not reduce the maximum number of shares of Stock
available for delivery under the Plan.

          (e) While the Stock is not Publicly Traded, an Optionee may not sell,
transfer, pledge, assign or otherwise alienate or hypothecate, any share of
Stock delivered under  the Plan without the prior written consent of the
Committee, which consent may be granted or withheld at the Committee's sole
discretion.

          (f) In the event that an Optionee shall cease to be employed by the
Company for any reason, including, without limitation, by reason of the death of
the Optionee, while the Stock is not Publicly Traded, the Company shall have the
right (but not the obligation) ("Call Right") to purchase (and the Optionee
                                 ----------
shall have the obligation to sell) all of such Optionee's shares of Stock
delivered under the Plan at an aggregate purchase price equal to the aggregate
Fair Market Value of the shares of Stock which were owned by the Optionee as of
the date of such cessation of employment.  The Call Right shall be exercised by
written notice to the Optionee, which notice shall fix the date of settlement of
the payment of the subject shares of Stock (the "Call Closing") at not less than
                                                 ------------
5 nor more than 30 days after the date such notice is given, provided that the
Call Closing cannot occur in any event until six months after the exercise date.
The purchase price to be paid for the subject shares of Stock, upon delivery to
the Company of all stock certificates representing Optionee's shares of Stock
and corresponding signed stock powers, shall be paid by check of the Company at
the Call Closing.  The Call Closing shall take place at the offices of the
Company at 1:00 p.m. on the date fixed in the exercise notice.  Such shares of
Stock shall be canceled on the books of Company upon the delivery of the
purchase price therefor.

          (g) After the date which is six months after the exercise of an Option
and for so long as the Stock is not Publicly Traded, an Optionee shall have the
right (but not the obligation) ("Put Right"), exercisable by written notice to
                                 ---------
the Company, to sell to the Company (and the Company shall have the obligation
to buy) any of such Optionee's shares of Stock delivered upon the exercise of
such Option at an aggregate purchase price equal to the aggregate Fair Market
Value of the shares of Stock which are put to the Company as of the date of the
notice of exercise of the Put Right.  The Company shall fix, by written notice
to the Optionee, the date of settlement of the payment of the subject shares of
Stock (the "Put Closing") at not less than 5 nor more than 30 days after the
            -----------
date such notice is given.  The purchase price to be paid for the subject shares
of Stock, upon delivery to the Company of all stock certificates representing
Optionee's shares of Stock and corresponding signed stock powers, shall be paid
by check of the Company at the Put Closing.  The Put Closing shall take place at
the offices of the

                                      -6-
<PAGE>

Company at 1:00 p.m. on the date fixed in the notice. Such shares of Stock shall
be canceled on the books of Company upon the delivery of the purchase price
therefor.

          5.  Eligibility.  Executive and other employees, including officers,
              -----------
of the Company and the Affiliates, directors (whether or not also employees) of
the Company or any Affiliate; and consultants to the Company and the Affiliates,
shall be eligible to become Optionees and receive Options in accordance with the
terms and conditions of the Plan, subject to the limitations on the granting of
ISOs set forth in Section 6(g).

          6.  Terms and Conditions of Stock Options.  All Options to purchase
              -------------------------------------
Stock granted under the Plan shall be either ISOs or Options other than ISOs.
To the extent that any Option does not qualify as an Incentive Stock Option
(whether because of its provisions or the time or manner of its exercise or
otherwise), such Option, or the portion thereof which does not so qualify, shall
constitute a separate Option other than an Incentive Stock Option.  Each Option
shall be subject to all the applicable provisions of the Plan, including the
following terms and conditions, and to such other terms and conditions not
inconsistent therewith as the Committee shall determine and which are set forth
in the applicable Agreement.  Options need not be uniform as to all grants and
recipients thereof.

          (a) The option exercise price per share of shares of Stock subject to
     each Option shall be determined by the Committee and stated in the
     Agreement; provided, however, that, subject to paragraphs (g)(C) and/or (i)
     of this Section 6, if applicable, such price applicable to any ISO shall
     not be less than 100% of the Fair Market Value of a share of Stock at the
     time that the Option is granted.

          (b) Each Option shall be exercisable in whole or in such installments,
     at such times and under such conditions, subject to Section 14, as may be
     determined by the Committee in its discretion and stated in the Agreement,
     and, in any event, over a period of time ending not later than ten (10)
     years from the date such Option was granted, subject to paragraph (g)(C) of
     this Section 6.

          (c) Each Option may be exercised by giving Notice to the Company
     specifying the number of shares of Stock to be purchased, which shall be
     accompanied by payment in full including applicable taxes, if any, in
     accordance with Section 9.  Payment shall be in any manner permitted by
     applicable law and prescribed by the Committee, in its discretion, and set
     forth in the Agreement, including, in the Committee's discretion, and
     subject to such terms, conditions and limitations as the Committee may
     prescribe, payment in accordance with a "cashless exercise" program
     established by the Committee and/or in Stock owned by the Optionee or by
     the Optionee and his or her spouse jointly.

          (d) No Optionee or other person shall become the beneficial owner of
     any shares of Stock subject to an Option, nor have any rights to dividends
     or other rights of a shareholder with respect to any such shares until he
     or she has exercised his or her Option in accordance with the provisions of
     the Plan and the applicable Agreement.

                                      -7-
<PAGE>

          (e) An Option may be exercised only if at all times during the period
     beginning with the date of the granting of the Option and ending on the
     date of such exercise, the Optionee was an employee, director or consultant
     of the Company or an Affiliate. Notwithstanding the preceding sentence, the
     Committee may determine in its discretion that an Option may be exercised
     prior to expiration of such Option following termination of such continuous
     employment, directorship or consultancy, whether or not exercisable at such
     time, to the extent provided in the applicable Agreement.

          (f) Subject to the terms and conditions and within the limitations of
     the Plan, the Committee may modify, extend or renew outstanding Options
     granted under the Plan, or accept the surrender of outstanding Options (up
     to the extent not theretofore exercised) and authorize the granting of new
     Options in substitution therefor (to the extent not theretofore exercised).

          (g) (A) Each Agreement relating to an Option shall state whether such
     Option will or will not be treated as an ISO.  No ISO shall be granted
     unless such Option, when granted, qualifies as an "incentive stock option"
     under Section 422 of the Code.  No ISO shall be granted to any individual
     otherwise eligible to participate in the Plan who is not an employee of the
     Company or any of its Subsidiaries on the date of granting of such Option.
     Any ISO granted under the Plan shall contain such terms and conditions,
     consistent with the Plan, as the Committee may determine to be necessary to
     qualify such Option as an "incentive stock option" under Section 422 of the
     Code.  Any ISO granted under the Plan may be modified by the Committee to
     disqualify such Option from treatment as an "incentive stock option" under
     Section 422 of the Code.

               (B) Notwithstanding any intent to grant ISOs, an Option granted
     under the Plan will not be considered an ISO to the extent that it,
     together with any other "incentive stock options" (within the meaning of
     Section 422 of the Code, but without regard to subsection (d) of such
     Section) under the Plan or any other "incentive stock option" plans of the
     Company and any Subsidiary, are exercisable for the first time by any
     Optionee during any calendar year with respect to Stock having an aggregate
     Fair Market Value in excess of $100,000 (or such other limit as may be
     required by the Code) as of the time the Option with respect to such Stock
     is granted.  The rule set forth in the preceding sentence shall be applied
     by taking Options into account in the order in which they were granted.

               (C) No ISO shall be granted to an individual otherwise eligible
     to participate in the Plan who owns (within the meaning of Section 424(d)
     of the Code), at the time the Option is granted, more than ten percent
     (10%) of the total combined voting power of all classes of stock of the
     Company or a Subsidiary. This restriction does not apply if at the time
     such ISO is granted the Option exercise price per share of Stock subject to
     the Option is at least 110% of the Fair Market Value of a share of Stock on
     the date such ISO is granted, and the ISO by its terms is not exercisable
     after the expiration of five (5) years from such date of grant.

                                      -8-
<PAGE>

          (h) An Option and any shares of Stock received upon the exercise of an
     Option shall be subject to such other transfer and/or ownership
     restrictions and/or legending requirements as the Committee may establish
     in its discretion and which are specified in the Agreement and may be
     referred to on the certificates evidencing such shares of Stock. The
     Committee may require an Optionee to give prompt Notice to the Company
     concerning any disposition of shares of Stock received upon the exercise of
     an ISO within: (i) two (2) years from the date of granting such ISO to such
     Optionee or (ii) one (1) year from the transfer of such shares of Stock to
     such Optionee or (iii) such other period as the Committee may from time to
     time determine. The Committee may direct that an Optionee with respect to
     an ISO undertake in the applicable Agreement to give such notice described
     in the preceding sentence, at such time and containing such information as
     the Committee may prescribe, and/or that the certificates evidencing shares
     of Stock acquired by exercise of an ISO refer to such requirement to give
     such notice.

          (i) In the event that a transaction described in Section 424(a) of the
     Code involving the Company or a Subsidiary is consummated, such as the
     acquisition of property or stock from an unrelated corporation, individuals
     who become eligible to participate in the Plan in connection with such
     transaction, as determined by the Committee, may be granted Options in
     substitution for stock options granted by another corporation that is a
     party to such transaction. If such substitute Options are granted, the
     Committee, in its discretion and consistent with Section 424(a) of the
     Code, if applicable, and the terms of the Plan, though notwithstanding
     paragraph (a) of this Section 6, shall determine the option exercise price
     and other terms and conditions of such substitute Options.

          7.  Transfer, Leave of Absence.  For purposes of the Plan, a transfer
              --------------------------
of an employee from the Company to an Affiliate, or vice versa, or from one
Affiliate to another, and a leave of absence, duly authorized in writing by the
Company or an Affiliate, shall not be deemed a termination of employment of the
employee.

          8.  Rights of Employees and Other Persons.  (a)  No person shall have
              -------------------------------------
any rights or claims under the Plan except in accordance with the provisions of
the Plan and the applicable Agreement.

          (b) Nothing contained in the Plan or in any Agreement shall be deemed
to (i) give any employee or director the right to be retained in the service of
the Company or any Affiliate nor restrict in any way the right of the Company or
any Affiliate to terminate any employee's employment or any director's
directorship at any time with or without cause or (ii) confer on any consultant
any right of continued relationship with the Company or any Affiliate, or alter
any relationship between them, including any right of the Company or an
Affiliate to terminate its relationship with such consultant.

                                      -9-
<PAGE>

          (c)  The adoption of the Plan shall not be deemed to give any employee
of the Company or any Affiliate or any other person any right to be selected to
participate in the Plan or to be granted an Option.

          (d)  Nothing contained in the Plan or in any Agreement shall be deemed
to give any employee the right to receive any bonus, whether payable in cash or
in Stock, or in any combination thereof, from the Company or any Affiliate, nor
be construed as limiting in any way the right of the Company or any Affiliate to
determine, in its sole discretion, whether or not it shall pay any employee
bonuses, and, if so paid, the amount thereof and the manner of such payment.

     9.   Tax Withholding Obligations. (a) The Company and/or any Affiliate are
          ---------------------------
authorized to take whatever actions are necessary and proper to satisfy all
obligations of Optionees (including, for purposes of this Section 9, any other
person entitled to exercise an Option pursuant to the Plan or an Agreement) for
the payment of all Federal, state, local and foreign taxes in connection with
any Options (including, but not limited to, actions pursuant to the following
paragraph (b) of this Section 9).

          (b)  Each Optionee shall (and in no event shall Stock be delivered to
such Optionee with respect to an Option until), no later than the date as of
which the value of the Option first becomes includible in the gross income of
the Optionee for income tax purposes, pay to the Company in cash, or make
arrangements satisfactory to the Company, as determined in the Committee's
discretion, regarding payment to the Company of, any taxes of any kind required
by law to be withheld with respect to the Stock subject to such Option, and the
Company and any Affiliate shall, to the extent permitted by law, have the right
to deduct any such taxes from any payment of any kind otherwise due to such
Optionee. Notwithstanding the above, the Committee may, in its discretion and
pursuant to procedures approved by the Committee, permit the Optionee to (i)
elect withholding by the Company of Stock otherwise deliverable to such Optionee
pursuant to such Option (provided, however, that the amount of any Stock so
withheld shall not exceed the minimum required withholding obligation taking
into account the Optionee's effective tax rate and all applicable Federal,
state, local and foreign taxes) and/or (ii) tender to the Company Stock owned by
such Optionee (or by such Optionee and his or her spouse jointly) and acquired
more than six (6) months prior to such tender in full or partial satisfaction of
such tax obligations, based, in each case, on the Fair Market Value of the Stock
on the payment date as determined by the Committee.

     10.  Changes in Capital. (a) The existence of the Plan and the Options
          ------------------
granted hereunder shall not affect in any way the right or power of the Board or
the stockholders of the Company to make or authorize any adjustment,
recapitalization, reorganization or other change in the Company's capital
structure or its business, any merger or consolidation of the Company or an
Affiliate, any issue of debt, preferred or prior preference stock ahead of or
affecting Stock, the authorization or issuance of additional shares of Stock,
the dissolution or liquidation of the Company or its Affiliates, any sale or
transfer of all or part of its assets or business or any other corporate act or
proceeding.

                                      -10-
<PAGE>

          (b)(i) Upon changes in the outstanding Stock by reason of a stock
dividend, stock split, reverse stock split, subdivision, recapitalization,
reclassification, merger, consolidation (whether or not the Company is a
surviving corporation), combination or exchange of shares of Stock, separation,
or reorganization, or in the event of an extraordinary dividend, "spin-off,"
liquidation, other substantial distribution of assets of the Company or
acquisition of property or stock or other change in capital of the Company, or
the issuance by the Company of shares of its capital stock without receipt of
full consideration therefor, or rights or securities exercisable, convertible or
exchangeable for shares of such capital stock, or any similar change affecting
the Company's capital structure the aggregate number, class and kind of shares
of stock available under the Plan as to which Options may be granted and the
number, class and kind of shares under each outstanding Option, the option price
per share and/or the vesting or exercise schedule applicable to any such Options
shall be appropriately adjusted by the Committee in its discretion to preserve
the benefits or potential benefits intended to be made available under the Plan
or with respect to any outstanding Options or otherwise necessary to reflect any
such change.

                 (ii) Except as set forth in the Agreement, fractional shares of
Stock resulting from any adjustment in Options pursuant to this subsection 10(b)
shall be aggregated until, and eliminated at, the time of exercise of the
affected Options. Notice of any adjustment shall be given by the Committee to
each Optionee whose Option has been adjusted and such adjustment (whether or not
such Notice is given) shall be effective and binding for all purposes of the
Plan.

          (c) In the event of (i) a stock sale, merger, consolidation,
combination, reorganization or other transaction (other than through a public
offering of common stock of the Company) resulting in less than fifty percent
(50%) of the combined voting power of the surviving or resulting entity being
owned by the shareholders of the Company immediately prior to such transaction,
(ii) the liquidation or dissolution of the Company or the sale or other
disposition of all or substantially all of the assets or business of the Company
(other than, in the case of either clause (i) or (ii) above, in connection with
any employee benefit plan of the Company or a Subsidiary), or (iii) a public
offering of the Stock (or any class of the Company's stock into which the Stock
may be converted upon any public offering) pursuant to a registration statement
declared effective under the Securities Act:

          (1) In its discretion and on such terms and conditions as it deems
     appropriate, the Committee may provide, either by the terms of the
     Agreement applicable to any Option or by a resolution adopted prior to the
     occurrence of such event, that any outstanding Option shall be accelerated
     and become immediately exercisable as to all or a portion of the shares of
     Stock covered thereby, notwithstanding anything to the contrary in the Plan
     or the Agreement.

          (2) In its discretion, and on such terms and conditions as it deems
     appropriate, the Committee may provide, either by the terms of the
     Agreement applicable to any Option or by resolution adopted prior to the
     occurrence of such event, that any outstanding Option shall be adjusted by
     substituting for Stock subject to such Option

                                      -11-
<PAGE>

     stock or other securities of the surviving corporation or any successor
     corporation to the Company, or a parent or subsidiary thereof, or that may
     be issuable by another corporation that is a party to the transaction
     whether or not such stock or other securities are publicly traded, in which
     event the aggregate exercise price (as applicable) shall remain the same
     and the amount of shares or other securities subject to the Option shall be
     the amount of shares or other securities which could have been purchased on
     the closing date or expiration date of such transaction with the proceeds
     which would have been received by the Optionee if the Option had been
     exercised in full (or with respect to a portion of such Option, as
     determined by the Committee, in its discretion) prior to such transaction
     or expiration date and the Optionee exchanged all of such shares in the
     transaction.

               (3) In its discretion, and on such terms and conditions as it
     deems appropriate, the Committee may provide, either by the terms of the
     Agreement applicable to any Option or by resolution adopted prior to the
     occurrence of such event, any outstanding Option shall, in each case, be
     converted into a right to receive cash following the closing date or
     expiration date of the transaction in an amount equal to the highest value
     of the consideration to be received in connection with such transaction for
     one share of Stock, or, if higher, the highest Fair Market Value of the
     Stock during the 30 consecutive business days immediately prior to the
     closing date or expiration date of such transaction, less the per share
     exercise price of such Option, multiplied by the number of shares of Stock
     subject to such Option, or a portion thereof.

               (4) The Committee may, in its discretion, provide that an Option
     cannot be exercised after such an event, to the extent that such Option
     becomes subject to any acceleration, adjustment or conversion in accordance
     with the foregoing paragraphs (1), (2) or (3) of this subsection 10(c).

No Optionee shall have any right to prevent the consummation of any of the
foregoing acts affecting the number of shares of Stock available to such
Optionee. Any actions or determinations of the Committee under this Subsection
10(c) need not be uniform as to all outstanding Options, nor treat all Optionees
identically. Notwithstanding the foregoing adjustments, in no event may any
Option be exercised after ten (10) years from the date it was originally
granted, and any changes to ISOs pursuant to this Section 10 shall, unless the
Committee determines otherwise, only be effective to the extent such adjustments
or changes do not cause a "modification" (within the meaning of Section
424(h)(3) of the Code) of such ISOs or adversely affect the tax status of such
ISOs.

          11.  Miscellaneous Provisions.   (a)  The Plan shall be unfunded.  The
               ------------------------
Company shall not be required to establish any special or separate fund or to
make any other segregation of assets to assure the issuance of shares of Stock
or the payment of cash upon exercise or payment of any Option. Proceeds from the
sale of shares of Stock pursuant to Options granted under the Plan shall
constitute general funds of the Company. The expenses of the Plan shall be borne
by the Company.

                                      -12-
<PAGE>

          (b)  Except as otherwise provided in this paragraph (b) of Section 11
or by the Committee, an Option by its terms shall be personal and may not be
sold, transferred, pledged, assigned, encumbered or otherwise alienated or
hypothecated otherwise than by will or by the laws of descent and distribution
and shall be exercisable during the lifetime of an Optionee only by him or her.
At the Committee's discretion, an Agreement may permit the exercise of an
Optionee's Option (or any portion thereof) after his or her death by the
beneficiary most recently named by such Optionee in a written designation
thereof filed with the Company, or, in lieu of any such surviving beneficiary,
as designated by the Optionee by will or by the laws of descent and
distribution. In the event any Option is exercised by the executors,
administrators, heirs or distributees of the estate of a deceased Optionee, or
such an Optionee's beneficiary, or the transferee of an Option, in any such case

named beneficiary of such Optionee, or the valid transferee of such Option, as
applicable.

          (c)(i) If at any time the Committee shall determine, in its
discretion, that the listing, registration and/or qualification of shares of
Stock upon any securities exchange or under any state or Federal law, or the
consent or approval of any governmental regulatory body, is necessary or
desirable as a condition of, or in connection with, the sale or purchase of
shares of Stock hereunder, no Option may be exercised in whole or in part unless

subsection 11(c), any Option affected by such suspension which shall not then
have expired or terminated shall be reinstated as to all shares available before

deems appropriate to reflect any such restrictions.

          (e)  The Committee may, in its discretion, extend one or more loans to
Optionees who are key employees, directors or consultants of the Company or an

Committee, the Company or the Board, in any case in accordance with the terms
and conditions of the Plan.

          (g)  Neither the adoption of the Plan nor anything contained herein

employees or consultants or directors, or grant or assume options or other
rights otherwise than under the Plan.

          (h)  The Plan shall be governed by and construed in accordance with

or without prior notice, amend, alter, suspend, or terminate the Plan,
retroactively or otherwise; provided, however, unless otherwise required by law
or specifically provided herein, no such amendment, alteration, suspension, or
termination shall be made which would impair the previously accrued rights of
any holder of an Option theretofore granted without his or her written consent,
or which, without first obtaining approval of the stockholders of the Company
(where such approval is necessary to satisfy (i) with regard to ISOs, any
requirements under the Code relating to ISOs or (ii) any applicable law,
regulation or rule), would:

          (a)  except as is provided in Section 10, increase the maximum number
               of shares of Stock which may be sold or awarded under the Plan;

          (b)  except as is provided in Section 10, decrease the minimum option

               Options may be exercised under Section 6(b).

          The Committee may amend the terms of any Option theretofore granted,
including any Agreement, retroactively or prospectively, but no such amendment
shall impair the previously accrued rights of any Optionee without his or her
written consent.

          14.  Duration.  Having been duly adopted by the Board of Directors and
               --------
subsequently approved and adopted by the stockholders of the Company, the Plan

               pursuant to the Plan's provisions; or

No Option may be granted under the Plan after the earliest to occur of the
events or dates described in the foregoing paragraphs (a) through (c) of this
Section 14; however, Options theretofore granted may extend beyond such date.

          No such termination of the Plan shall affect the previously accrued
rights of any Optionee hereunder and all Options previously granted hereunder
shall continue in force and in operation after the termination of the Plan,
except as they may be otherwise terminated in accordance with the terms of the
Plan or the Agreement.

     6.7  Rights Not Transferable.  No rights with regard to a Grant or to
          -----------------------
purchase shares of Stock under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than as provided in Section 8.10 hereof)
by the Eligible Employee. Any such attempt at assignment, transfer, pledge or
other disposition shall be without effect. No right of an Eligible Employee
under this Plan may be exercised after his death, by his personal representative
or anyone else, or during his lifetime by any person other than the Eligible
Employee.

              Nontransferability of Stock; Call Right; Put Right
              --------------------------------------------------

     7.1  Nontransferability.  While the Stock or any security to which such
          ------------------
Stock is convertible is not Publicly Traded, a Participant may not sell,
transfer, pledge, assign or otherwise alienate or hypothecate, any share of
Stock received pursuant to the Plan without the prior written consent of the
Committee, which consent may be granted or withheld at the Committee's sole
discretion; provided, however, that notwithstanding the foregoing, a Participant
may make a one-time transfer of some or all of the shares of Stock received
pursuant to the Plan to a trust, the beneficiary or beneficiaries of which are
the Participant and/or the Participant's immediate family (i.e., the
Participant's mother, father, sisters, brothers, children and grandchildren),
provided that (i) the trustee(s) thereof shall agree on behalf of such trust to
abide by the terms and conditions of the Plan and shall execute and deliver all
such documentation as shall be deemed necessary by the Company in order to
effect such agreement and (ii) the terms of such trust provide that the shares
of Stock received pursuant to the Plan must be held of record by one person only
until such time, if any, as the Stock or any security to which such Stock is
convertible becomes Publicly Traded.

     7.2  Call Right of Company Upon Termination of Employment of Participant.
          -------------------------------------------------------------------
In the event that (a) a Participant shall cease to be employed by the Company
for any reason, including, without limitation, by reason of the death of the
Participant, while the Stock or any security to which such Stock is convertible
is not Publicly Traded or (b) if at any time on or after March 15, 2003 the
Stock or any security to which such Stock is convertible is not Publicly Traded,
the Company shall have the right (but not the obligation) ("Call Right") to
                                                            ----------
purchase (and the Participant shall have the obligation to sell) all of such
Participant's shares of Stock received pursuant to the Plan. The per share
purchase price shall be determined by the Committee and shall be not less than
the greater of (a) the Fair Market Value of a share of Stock and (b) in the
event that a Transfer of Interest shall have occurred prior to the exercise of
such Call Right, the Recent Transaction Value of a share of Stock. Such prices
shall be calculated as of the date of such cessation of employment (if the Call
Right is exercised pursuant to (a) hereof) or the date the notice of exercise
described in the next sentence of this Section 7.2 is received by the
Participant pursuant to Section 8.16 (if the Call Right is exercised pursuant to
(b) hereof); provided, however, that, notwithstanding the foregoing, if the Call
Right is exercised within six (6) months of the Participant's purchase of Shares
hereunder, the aggregate purchase price for such Shares shall be not less than
the aggregate Fair Market Value of such shares of Stock as of the date which is
six (6) months after such purchase. The Call Right shall be exercised by written
notice to the Participant, which notice shall fix the date of settlement of the
payment of

                                      -7-
<PAGE>

the subject shares of Stock (the "Call Closing") at not less than 5 nor more
                                  ------------
than 30 days after the date such notice is given, provided that the Call Closing
cannot occur in any event until at least six months after the Exercise Date. The
purchase price to be paid for the subject shares of Stock, upon delivery to the
Company of all stock certificates representing Participant's shares of Stock and
corresponding signed stock powers, shall be paid by check of the Company at the
Call Closing. The Call Closing shall take place at the offices of the Company at
1:00 p.m. on the date fixed in the exercise notice. Such shares of Stock shall
be canceled on the books of Company upon the delivery of the purchase price
therefor.

     7.3  Put Right to the Company.  After the date which is six months after
          ------------------------
the Exercise Date and for so long as the Stock or any security to which such
Stock is convertible is not Publicly Traded, a Participant shall have the right
(but not the obligation) ("Put Right"), exercisable by written notice to the
                           ---------
Company, to sell to the Company (and the Company shall have the obligation to
buy) any of such Participant's shares of Stock received pursuant to the Plan.
The per share purchase price shall be determined by the Committee and shall be
not less than the greater of (a) the Fair Market Value of a share of Stock and
(b) in the event that a Transfer of Interest shall have occurred prior to the
exercise of such Put Right, the Recent Transaction Value of a share of Stock, in
each case calculated as of the date of the notice of exercise of the Put Right.
The Company shall fix, by written notice to the Participant, the date of
settlement of the payment of the subject shares of Stock (the "Put Closing") at
                                                               -----------
not less than 5 nor more than 30 days after the date such notice is given. The
purchase price to be paid for the subject shares of Stock, upon delivery to the
Company of all stock certificates representing Participant's shares of Stock and
corresponding signed stock powers, shall be paid by check of the Company at the
Put Closing. The Put Closing shall take place at the offices of the Company at
1:00 p.m. on the date fixed in the notice. Such shares of Stock shall be
canceled on the books of Company upon the delivery of the purchase price
therefor.

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

     8.1  Stock Adjustments.
          -----------------

     (a)  The existence of the Plan and the Grants granted hereunder shall not
affect in any way the right or power of the Board or the stockholders of the
Company to make or authorize any adjustment, recapitalization, reorganization or
other change in the Company's capital structure or its business, any merger or
consolidation of the Company or an Affiliate, any issue of debt, preferred or
prior preference stock ahead of or affecting Stock, the authorization or
issuance of additional shares of Stock, the dissolution or liquidation of the
Company or its Affiliate, any sale or transfer of all or part of its assets or
business or any other corporate act or proceeding.

     (b)  Upon changes in the outstanding Stock by reason of a stock dividend,
stock split, reverse stock split, subdivision, recapitalization,
reclassification, merger, consolidation (whether or not the Company is a
surviving corporation), combination or exchange of shares of Stock, separation,
or reorganization, or in the event of an extraordinary dividend, "spin-off,"
liquidation, other substantial distribution of assets of the Company or
acquisition of property or stock or

                                      -8-
<PAGE>

other change in capital of the Company, or the issuance by the Company of shares
of its capital stock without receipt of full consideration therefor, or rights
or securities exercisable, convertible or exchangeable for shares of such
capital stock, or any similar change affecting the Company's capital structure
the aggregate number, class and kind of shares of stock available under the Plan
and the number, class and kind of shares under each outstanding Grant and the
price per share applicable to any such Grants shall be appropriately adjusted by
the Committee in its discretion to preserve the benefits or potential benefits
intended to be made available under the Plan or with respect to any outstanding
Grants or otherwise necessary to reflect any such change.

     8.2  Conditions Upon Issuance of Shares.  Shares of Stock shall not be
          ----------------------------------
issued with respect to a Grant unless the exercise of such Grant and the
issuance and delivery of such shares of Stock pursuant thereto shall comply with
all applicable provisions of law, domestic or foreign, including, without
limitation, the Securities Act, the Exchange Act, the rules and regulations
promulgated thereunder, and the requirements of any stock exchange upon which
the shares may then be listed, and shall be further subject to the approval of
counsel for the Company with respect to such compliance. As a condition to the
exercise of a Grant hereunder, the Company may require the person exercising
such Grant to represent and warrant at the time of any such exercise that the
shares of Stock are being purchased only for investment and without any present
intention to sell or distribute such shares of Stock if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law. The certificates evidencing such
shares of Stock may include a legend that the Committee deems appropriate to
reflect such restrictions.

     8.3  Necessity for Delay.
          --------------------

     (a) If at any time the Committee shall determine, in its discretion, that
the listing, registration and/or qualification of shares of Stock upon any
securities exchange or under any state or Federal law, or the consent or
approval of any governmental regulatory body, is necessary or desirable as a
condition of, or in connection with, the sale or purchase of shares of Stock
hereunder, no Grant may be exercised hereunder in whole or in part unless and
until such listing, registration, qualification, consent and/or approval shall
have been effected or obtained, or otherwise provided for, free of any
conditions not acceptable to the Committee.

     (b) If at any time counsel to the Company shall be of the opinion that any
sale or delivery of shares of Stock pursuant to a Grant is or may be in the
circumstances unlawful under the statutes, rules or regulations of any
applicable jurisdiction, the Company shall have no obligation to make such sale
or delivery, or to make any application or to effect or to maintain any
qualification or registration under the Securities Act, or otherwise with
respect to shares of Stock or Grants, and the right to exercise any Grant shall
be suspended until, in the opinion of said counsel, such sale or delivery shall
be lawful or will not result in the imposition of taxes on the Company.

     (c) Notwithstanding anything in the Plan to the contrary, the Company shall
have no obligation under the Plan to cause any shares of Stock to be registered
or qualified under any

                                      -9-
<PAGE>

federal or state law or listed on any stock exchange or admitted to any national
marketing system.

     8.4  Amendment and Termination of the Plan.  The Committee may at any time
          -------------------------------------
for any reason amend or terminate the Plan; provided, however, that in the event
the Plan is terminated pursuant hereto, the Put Right provided for in Section
7.3 shall survive until such right expires according to its terms, if ever.
None of Article 2, Sections 7.2, 7.3 or 8.4 may be amended in any manner without
the prior written approval of Participants holding 51% or more of the Shares
purchased hereunder.

     8.5  Application of Funds.  The Plan shall be unfunded. The Company shall
          --------------------
not be required to establish any special or separate fund or to make any other
segregation of assets to assure the issuance of shares of Stock upon exercise of
any Grant.  Proceeds from the sale of shares of Stock pursuant to Grants granted
under the Plan shall constitute general funds of the Company.

     8.6  No Obligation to Participate.  The offering of any Stock under the
          ----------------------------
Plan shall impose no obligation upon any Eligible Employee to subscribe to
purchase any such shares.

     8.7  No Implied Rights to Employees.  The existence of the Plan, and the
          ------------------------------
offering of shares of Stock under the Plan, shall in no way give any Employee
the right to continued employment, give any Employee the right to receive any
Stock or any additional Stock under the Plan, or otherwise provide any Employee
any rights not specifically set forth in the Plan.

     8.8  Withholding.
          -----------

     (a)  The Company shall have the right to withhold from an Eligible
Employee's compensation the amount necessary to meet any applicable federal,
state or local withholding obligation, including any withholding necessary to
make available any tax deductions to the Company due to sale or early
disposition of the Stock issued to the Eligible Employee under the Plan.

     (b)  Whenever the Company proposes or is required to issue or transfer
shares of Stock under the Plan, the Company shall have the right to require an
Eligible Employee to remit to the Company an amount sufficient to satisfy any
federal, state or local withholding tax liability prior to the delivery of any
certificate or certificates for such shares. Whenever under the Plan payment is
to be made in cash, such payments shall be made net of an amount sufficient to
satisfy any federal, state or local withholding tax liability.

     8.9  Duration.  Having been duly adopted by the Board of Directors and
          --------
subsequently approved and adopted by the stockholders of the Company, the Plan
is effective as of October 20, 1998 (the "Effective Date"). The Plan, unless
                                          --------------
sooner terminated as provided in Section 8.4, shall terminate on the date the
Stock is Publicly Traded.

     8.10 Designation of Beneficiary.
          --------------------------

                                      -10-
<PAGE>

     (a)  An Eligible Employee may file with the Company on a form provided for
such purpose by the Company a written designation of a beneficiary who is to
receive any shares of Stock and/or cash from the Eligible Employee's Account
under the Plan in the event of such Eligible Employee's death subsequent to an
Exercise Date on which a Grant is exercised but prior to delivery to such
Eligible Employee of such shares. In addition, an Eligible Employee may file a
written designation of a beneficiary who is to receive any cash from the
Eligible Employee's Account under the Plan in the event of such Eligible
Employee's death prior to exercise of a Grant.

     (b)  Such designation of beneficiary may be changed by the Eligible
Employee at any time by written notice to the Company on a form supplied by the
Company for such purpose. In the event of the death of an Eligible Employee and
in the absence of a beneficiary validly designated under the Plan who is living
at the time of such Eligible Employee's death, the Company shall deliver such
shares and/or cash to the executor or administrator of the estate of the
Eligible Employee, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the Eligible Employee, or if no spouse, dependent or relative is
known to the Company, then to such other person as the Company may designate.

     8.11  Rights of Stock.  Each share of Stock offered pursuant to the Plan
           ---------------
shall have the rights given such Stock in the Certificate of Incorporation of
the Company, as the same may be amended from time to time.

     8.12  Governing Law.  The Plan shall be governed by and construed in
           -------------
accordance with the laws of California, without regard to such state's choice of
law provisions, except as superseded by applicable Federal law.

     8.13  Expenses of the Plan.  The Company shall bear all costs and expenses
           ---------------------
incurred in administering the Plan, including expenses of issuing shares of
Stock pursuant to any Grants exercised hereunder.

     8.14  Construction.    The words "Section," "paragraph" and "clause" shall
           -------------
refer to provisions of the Plan, unless expressly indicated otherwise. Wherever
any words are used in the Plan in the masculine gender they shall be construed
as though they were also used in the feminine gender in all cases where they
would so apply, and wherever any words are used herein in the singular form they
shall be construed as though they were also used in the plural form in all cases
where they would so apply.

     8.15  Limits of Liability.
           -------------------

     (a) Any liability of the Company or any Affiliate to any Eligible Employee
with respect to any Grant shall be based solely upon contractual obligations
created by the Plan.

     (b) Neither the Company nor any Affiliate nor any member of the Committee
or the Board, nor any other person participating in any determination of any
question under the Plan, or

                                      -11-
<PAGE>

in the interpretation, administration or application of the Plan, shall have any
liability, in the absence of bad faith, to any party for any action taken or not
taken in connection with the Plan, except as may expressly be provided by
statute.

     8.16  Notices.  All notices or other communications (i) by a Participant to
           -------
the Company in connection with the Plan shall be deemed to have been duly given
when received in the form specified by the Company at the location, or by the
person, designated by the Company for the receipt thereof and (ii) by the
Company to a Participant in connection with the Plan shall be deemed to have
been duly given when received by the participant or, if earlier, five days after
deposit in the United States mail by certified or registered mail, return
receipt requested, first class postage prepaid, addressed to the Participant at
his or her address as shown on the records of the Company or as such participant
may request by written notice to the Company hereunder.

     8.17  No Enlargement of Employee Rights.  The Plan is purely voluntary on
           ---------------------------------
the part of the Company, and the continuance of the Plan shall not be deemed to
constitute a contract between the Company and any Employee, or to be
consideration for or a condition of the employment of any Employee. Nothing
contained in this Plan shall be deemed to give any Employee the right to be
retained in the employment of the Company, any Affiliate or a successor
corporation, or to interfere with the right of the Company or any such
corporation to discharge or retire any Employee thereof at any time. No Employee
shall have any right to or interest in Grants authorized hereunder prior to the
grant of a Grant to such Employee, and upon such grant he or she shall have only
such rights and interests as are expressly provided herein, subject, however, to
all applicable provisions of the Company's Certificate of Incorporation, as the
same may be amended from time to time.

term incentive payment and/or (ii) will have the actuarial equivalent of his
supplemental defined benefits converted to a lump sum and credited to his
Account hereunder.  No such election shall become effective if the Participant's
Separation from Service occurs within one year of such election.

or losses shall be allocated at least annually and on such valuation dates as
the Plan Administrator shall determine.  The Plan Administrator shall determine
the rate of earnings which shall be credited to the Participants' Accounts,
which rate may be fixed or variable and which may be based upon any index or
benchmark selected by the Plan Administrator or upon the actual earnings or
losses on any real or phantom investment made by Infonet as may be directed by
the Plan Administrator or by the Participants.  To the

receive a distribution of his Account in a lump sum on the earlier of (a) the
date on which the Participant begins receiving retirement benefits under the
Infonet Pension Plan or (b) the date which is five years from the date on which
his Separation from Service occurs; provided, however, that the Participant may
elect to receive his distribution at an earlier date and/or in a form other than

     hardship is or may be relieved  (i) through reimbursement or compensation
     by insurance or otherwise, (ii) by liquidation of the Participant's assets,
     to the extent the liquidation of such assets would not itself cause severe
     financial hardship, or (iii) by cessation of deferrals under IDIP,

          (c) the denial of the Participant's Hardship withdrawal request would
     result in severe financial hardship to the Participant, and

          (d) the Participant has not received a Hardship withdrawal within the
     12 month period preceding the withdrawal.

          5.6  Change of Control.  Notwithstanding the terms of a Participant's
               -----------------
Participation Form or any election to defer under the IDIP, upon the occurrence
of a Change in Control, each Participant's Account shall be distributed to him
in a lump sum, as soon as practicable after such Change in Control; provided,
however that a Participant may make an irrevocable and unamendable election, by
executing and delivering to the Plan Administrator a new Participation Form, at
least one year prior to the date on which the Change in Control occurs to defer
the receipt of the amount credited to his Account until such amount is otherwise
distributable pursuant to the terms of the IDIP; and provided, further, that the
Plan Administrator may, in its sole discretion, upon written notice to the
Participant, within one year before, or 60 days after, such Change of Control,
defer distributions to a Participant who has not incurred a Separation from
Service until such amount is otherwise distributable to such Participant
pursuant to the terms of the IDIP.

action, failure to act, or other conduct in their official capacity under the
IDIP, except with respect to any Liability which results from an individual's
own gross negligence or willful misconduct.

                                   ARTICLE IX

                            Miscellaneous Provisions
                            ------------------------

          9.1  No Assignment of Benefits.  No benefit payable under, or interest
               -------------------------
in, the IDIP shall be subject in any manner to anticipation, alienation, sale,
transfer, assignment, pledge, encumbrance, garnishment, or charge, and any
attempt to do so shall be void.  Any such benefit or interest shall not in any
manner be liable for or subject to the debts, contracts, liabilities,
engagements, or torts of any Participant or his Beneficiaries.  If the Plan
Administrator finds that any Participant or Beneficiary has become bankrupt or
that any attempt has been made to anticipate, alienate, sell, transfer, assign,
pledge, encumber, or charge any benefit payable under, or interest in, the IDIP,
the Plan Administrator shall hold or apply such benefit or interest or any part
thereof to or for the benefit of such Participant or Beneficiary.

          9.2  Releases.  In connection with any benefit or benefit payment
               --------
under the IDIP, or the designation of any Beneficiary or any election or other
action taken or to be taken under the IDIP by any Participant or any other
person, the Plan Administrator or its delegate, may require such consents or
releases as the Plan Administrator or its delegate determines to be appropriate,
and further may require any such designation election or other action to be in
writing and in form satisfactory to the Plan Administrator or its delegate.

          9.3  No Waiver.  The failure of an Employer, the Plan Administrator or
               ---------
any other person acting on behalf thereof to demand that a Participant or other
person claiming rights with respect to a Participant perform any act which such
Participant or person is or may be required to perform hereunder shall not
constitute a waiver of

                                     -13-
<PAGE>

the right to require such act. The exercise of or failure to exercise any
discretion reserved to an Employer, the Plan Administrator or its delegate, to
grant or deny any benefit to any Participant or other person under the IDIP
shall in no way require the Employer, the Plan Administrator or its delegate to
similarly exercise or fail to exercise such discretion with respect to any other
Participant or person.


          9.4  No Contract.  The IDIP is strictly a voluntary undertaking on the
               -----------
part of the Employers and shall not be deemed to constitute a contract or part
of a contract between an Employer and any Employee or other person, nor shall it
be deemed to give any Employee the right to be retained for any specified period
of time in the employ of an Employer or to interfere with the right of an
Employer to discharge any Employee at any time, with or without cause, nor shall
the IDIP interfere with the right of an Employer to establish the terms and
conditions of employment of any Employee.

          9.5  Nature of IDIP Benefits.  The IDIP shall not be "funded" for tax
               -----------------------
purposes or within the meaning of ERISA.  It is intended that the IDIP shall not
be a "pension plan" for purposes of ERISA and, therefore, that the IDIP shall
not be subject to any of the provisions of ERISA.  All payments hereunder to
Participants or their Beneficiaries shall be paid from the general assets of the
Employers.  The Employers shall not, by virtue of any provisions of the IDIP or
by any action of any person, be deemed to be trustees or other fiduciaries of
any property for any Participant or his Beneficiaries, and the liabilities of an
Employer to any Participant or his Beneficiaries pursuant to the IDIP shall be
those of a debtor pursuant only to such contractual obligations as are created
by the IDIP; no such obligation of an Employer shall be deemed to be secured by
any pledge or other encumbrance on any property of the Employer.  Benefits under

                                      -14-
<PAGE>

the IDIP shall be payable from the general assets of the Employer or pursuant to
such other means as the Employer deems appropriate and no Participant or other
person shall be entitled to look to any source for payment of such benefits
other than the general assets of the Employer.  No Participant shall have any
interest in any fund used for measuring the rate of Earnings, and the Employer
may, but shall not be obligated to, invest its funds in the same manner as the
measuring factors for the rate of Earnings (as discussed in Section 4.3 hereof)
elected by the Participants.  To the extent that any Participant or any of his
beneficiaries acquires a right to receive payment under the IDIP, such right
shall be no greater than the right of an unsecured general creditor of the
Employers.

          9.6  Governing Law.  The IDIP shall be construed, administered and
               -------------
governed in all respects under and by applicable federal laws and, where state
law is applicable, the laws of the State of California.

          9.7  Pronouns and Plurality.  The masculine pronoun shall include the
               ----------------------
feminine pronoun, and the singular the plural where the context so indicates.

          9.8  Titles.  Titles are provided herein for convenience of reference
               ------
only and are not to serve as a basis for interpretation or construction of the
IDIP.

          9.9  References.  Unless the context clearly indicates to the
               ----------
contrary, a reference to a statute, regulation or document shall be construed as
referring to any subsequently enacted, adopted or executed statute, regulation
or document.

<PAGE>

          9.10  Severable Provisions.  The provisions of the IDIP are severable
                --------------------
and if any one or more articles, sections, subsections, paragraphs, clauses or
provisions of the IDIP is determined to be illegal, indefinite, invalid or
otherwise unenforceable, in whole or in part, the remaining provisions, and any
partially unenforceable provisions to the extent enforceable in any
jurisdiction, shall continue in full force and effect and shall be binding and
enforceable.

          9.11  Inability to Ascertain Amount of Payment or to Locate Payee.  If
                -----------------------------------------------------------

Section 4.4 hereof within one (1) year of the date of such retirement, may be
exercised after such termination for a period of one (1) year from the date of
such termination or until the termination of the Plan, whichever period is
shorter.

          (d)  Notwithstanding the provisions of Section 5.1, if the Participant
dies after termination of his employment with the Company or an Affiliate under
paragraphs (b) or (c) of this Section 5.2 above during the one (1) year period
specified in such paragraphs, the SARs, to the extent they would have been
exercisable in accordance with such applicable paragraph (b) or (c) as of the
date of the Participant's death, may be exercised after the Participant's death
by the Participant's designated beneficiary, heir, the legal representative of
his estate or by the legatee of the Participant under his last will until the
expiration of the period of two (2) years from the date of his death or until
the termination of the Plan, whichever period is shorter.

          (e)  If the Participant's employment with the Company or an Affiliate
shall terminate under any circumstances not otherwise described in this Section
4.4, the SARs, to the extent exercisable in accordance with Section 4.4 hereof
as of the date of such termination, may be exercised after such termination but
may not be exercised after the expiration of the period of three (3) months from
the date of such termination or until the termination of the Plan, whichever
period is the shorter.

     5.3  Redemption by the Company.  The Company shall have the right at its
          -------------------------
option ("Redemption Right") to redeem any SARs received pursuant to a Grant
         ----------------
under the Plan at the Redemption Price.  The Redemption Right shall be exercised
by written notice to the Participant (the date this notice is given by the
Company, calculated pursuant to Section 6.12(b), the "Redemption Date"), which
                                                      ---------------
notice shall fix the date of settlement of the payment of the Redemption Price
(the "Redemption Closing") at not less than 5 nor more than 30 days after the
      ------------------
date such notice is given.  The Redemption Price to be paid for the subject SARs
shall be paid by

have no further rights pursuant thereto upon the delivery of the Redemption
Price therefor.

exchangeable for shares of such capital stock, or any similar change affecting
the Company's capital structure the, aggregate number of SARs and the class and
kind of shares of stock defined as "Stock" under the Plan and the number of SARS
under each outstanding Grant shall be appropriately adjusted by the Committee in
its discretion to preserve the benefits or potential benefits intended to be
made available under the Plan or with respect to any outstanding Grants or
otherwise necessary to reflect any such change.

     6.2  Conditions Upon Issuance of SARs.  SARs shall not be issued pursuant

the circumstances unlawful under the statutes, rules or regulations of any
applicable jurisdiction, the Company shall have no obligation to make such
redemption and the Redemption Right, if any, pertaining to the subject SARs
shall be suspended until, in the opinion of said counsel, such redemption shall

additional SARs under the Plan, give any Employee any rights with regard to the
Stock or otherwise provide any Employee any rights not specifically set forth in
the Plan.

     6.7   Term of Plan.  Having been duly adopted by the Board of Directors and

maintain the Register pursuant to Section 10.6(e), and a subaccount therein for
each Lender, in which shall be recorded (i) the amount of each Loan made
hereunder and any Note evidencing such Loan, the Type of such Loan and each
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Lender
hereunder and (iii) both the amount of any sum received by the Administrative
Agent hereunder from the Borrower and each Lender's share thereof.

          (d   The entries made in the Register and the accounts of each Lender
maintained pursuant to Section 2.6(b) shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the

Register or any such account, or any error therein, shall not in any manner
affect the obligation of the Borrower to repay (with applicable interest) the
Loans made to the Borrower by such Lender in accordance with the terms of this
Agreement.

          (e   The Borrower agrees that, upon the request to the Administrative
Agent by any Lender, the Borrower will execute and deliver to such Lender a
promissory note of the Borrower evidencing any Term Loans or Revolving Credit
Loans, as the case may be, of such Lender, substantially in the forms of Exhibit
D-1 or D-2, respectively, with appropriate insertions as to date and principal
amount.

          2.7  Commitment Fees, etc.  (a)  The Borrower agrees to pay to the
               ---------------------
Administrative Agent for the account of each Revolving Credit Lender a
commitment fee for the period from and including the date hereof to and
including the Revolving Credit Termination Date, computed at the Commitment Fee
Rate on the average daily amount of the Available Revolving Credit Commitment of
such Lender during the period for which payment is made, payable quarterly in
arrears on the last day of each March, June, September and December and on the
Revolving Credit Termination Date, commencing on the first of such dates to
occur after the date hereof.

          (b   The Borrower agrees to pay to the Administrative Agent for the
account of each Delayed Draw Term Loan Lender a commitment fee for the period
from and including the date hereof to and including the Delayed Draw Termination
Date, computed at the Commitment Fee Rate on the average daily amount of the
Available Delayed Draw Term Loan Commitment of such Lender during the period for
which payment is made, payable quarterly in arrears on the last day of each
March, June, September and December and on the Delayed Draw Termination Date,
commencing on the first of such dates to occur after the date hereof.

               ---------------------------------------
have the right, upon not less than three Business Days' notice to the
Administrative Agent, to terminate the Revolving Credit Commitments or, from
time to time, to reduce the aggregate amount of the Revolving Credit
Commitments; provided that no such termination or reduction of Revolving Credit
             --------
Commitments shall be permitted if, after giving effect thereto and to any
prepayments of the Revolving Credit Loans made on the effective date thereof,
the Total Revolving Extensions of Credit would exceed the Total Revolving Credit
Commitments. Any such reduction shall be in an amount equal to $1,000,000, or a
whole multiple thereof (or, if the Revolving Credit Commitments are less than
$1,000,000, such lesser amount), and shall reduce permanently the Revolving
Credit Commitments then in effect.

          (b   The Borrower shall have the right, upon not less than three
Business Days' notice to the Administrative Agent, to terminate the Delayed Draw
Term Loan Commitments, or, from time to time, reduce the aggregate amount of
Delayed Draw Term Loan Commitments. Any such reduction shall be in an amount
equal to $1,000,000, or a whole multiple thereof (or, if the Delayed Draw Term
Loan Commitments are less than $1,000,000, such lesser amount), and shall reduce
permanently the Delayed Draw Term Loan Commitments then in effect.

          2.9  Optional Prepayments. The Borrower may at any time and from time
               --------------------
to time prepay the Loans, in whole or in part, without premium or penalty
(except as otherwise provided herein), upon irrevocable notice delivered to the
Administrative Agent at least three Business Days prior thereto in the case of
Eurodollar Loans and at least one Business Day prior thereto in the case of Base
Rate Loans, which notice shall specify the date and amount of prepayment and
whether the prepayment is of Eurodollar Loans or Base Rate Loans; provided, that
                                                                  --------
if a Eurodollar Loan is prepaid on any day other than the last day of the
Interest Period applicable thereto, the Borrower shall also pay any amounts
owing pursuant to Section 2.19. Upon receipt of any such notice the
Administrative Agent shall promptly notify each relevant Lender thereof. If any
such notice is given, the amount specified in such notice shall be due and
payable on the date specified therein, together with (except in the case of
Revolving Credit Loans that are Base Rate Loans) accrued interest to such date
on the amount prepaid. Partial prepayments of Loans shall be in an aggregate
principal amount of $1,000,000 or a whole multiple thereof.

          2.10 Mandatory Prepayments and Commitment Reductions.  (a)  Unless
               -----------------------------------------------
the Required Prepayment Lenders shall otherwise agree, subject to Section
2.16(d), if any Capital Stock shall be issued by the Borrower or any of its
Subsidiaries, on the date of such issuance an amount equal to 50% (or, if the
Consolidated Leverage Ratio, determined as at the end of the most recent period
of four consecutive fiscal quarters ended prior to the required date of
prepayment for which the relevant financial information is available on a pro

toward the prepayment of the Term Loans, as set forth in Section 2.10(e);
provided that the first $750,000,000 of Net Cash Proceeds received by the
- --------
Borrower of an IPO of Capital Stock of the Borrower shall be excluded from the
foregoing requirement.

          (b   Unless the Required Prepayment Lenders shall otherwise agree,
subject to Section 2.16(d), if any Indebtedness (in respect of which the
Borrower or any Subsidiary received  Net Cash Proceeds) shall be incurred by the
Borrower or any of its Subsidiaries (excluding any Indebtedness incurred in
accordance with Section 7.2), an amount equal to 100% of the Net Cash Proceeds
thereof shall be applied on the date of such incurrence toward the prepayment of
the Term Loans and/or the reduction of the Revolving Credit Commitments, as set
forth in Section 2.10(e); provided that the first $100,000,000 of Net Cash
                          --------
Proceeds of such Indebtedness constituting senior subordinated Indebtedness (if
such Indebtedness is permitted to be incurred hereunder) shall be excluded from
the foregoing requirement.

          (c   Unless the Required Prepayment Lenders shall otherwise agree,
subject to Section 2.16(d), if on any date the Borrower or any of its
Subsidiaries shall receive Net Cash Proceeds from any Asset Sale or Recovery
Event then, unless a Reinvestment Notice shall be delivered in respect thereof,
on such date the Term Loans shall be prepaid, and/or the Revolving Credit
Commitments shall be reduced, by an amount equal to 100% of the amount of such
Net Cash Proceeds, as set forth in Section 2.10(e); provided, that,
                                                    --------
notwithstanding the foregoing, (i) the aggregate Net Cash Proceeds of Asset
Sales and Recovery Events that may be excluded from the foregoing requirement
pursuant to a Reinvestment Notice shall not exceed $10,000,000 in any fiscal

reduced, by an amount equal to the Reinvestment Prepayment Amount with respect
to the relevant Reinvestment Event, as set forth in Section 2.10(e).

          (d)  Unless the Required Prepayment Lenders shall otherwise agree,
subject to Section 2.16(d), if, for any fiscal year of the Borrower commencing
with the fiscal year beginning in 2002, there shall be Excess Cash Flow, on the
relevant Excess Cash Flow Application Date the Term Loans shall be prepaid by an
amount equal to 50% (or, if the Consolidated Leverage Ratio as of the last day
of such fiscal year is less than 4.0 to 1.0, 25%) of such Excess Cash Flow, as
set forth in Section 2.10(e).  Each such prepayment and commitment reduction
shall be made on a date (an "Excess Cash Flow Application Date") no later than
                             ---------------------------------
five days after the earlier of (i) the date on which the financial statements of
the Borrower referred to in Section 6.1(a), for the fiscal year with respect to
which such prepayment is made, are required to be delivered to the Lenders and
(ii) the date such financial statements are actually delivered.

          (e)  Subject to Section 2.16, amounts to be applied in connection with
prepayments and Commitment reductions made pursuant to this Section shall be
applied, first, to the prepayment of the Term Loans and, second, if required
         -----                                           ------
above and after the Term Loans are paid in full, to reduce permanently the
Revolving Credit Commitments.  Any such reduction of the Revolving Credit
Commitments shall be accompanied by prepayment of the Revolving Credit Loans to
the extent, if any, that the Total Revolving Extensions of Credit exceed the
amount of the Total Revolving Credit Commitments as so reduced, provided that if
                                                                --------
the aggregate principal amount of Revolving Credit Loans then outstanding is
less than the amount of such excess (because L/C Obligations constitute a
portion thereof), the Borrower shall, to the extent of the balance of such
excess, replace outstanding Letters of Credit and/or deposit an amount in cash
or Cash Equivalents in an interest bearing cash collateral account established
with the Administrative Agent for the benefit of the Lenders on terms and
conditions reasonably satisfactory to the Administrative Agent.  The application
of any prepayment of Loans under any Facility pursuant to this Section shall be
made, first, to Base Rate Loans under such Facility and, second, to Eurodollar
      -----                                              ------
Loans under such Facility.  Each prepayment of the Loans under this Section
(except in the case of Revolving Credit Loans that are Base Rate Loans) shall be
accompanied by accrued interest to the date of such prepayment on the amount
prepaid.

          2.11  Conversion and Continuation Options.  (a) The Borrower may elect
                -----------------------------------
from time to time to convert Eurodollar Loans to Base Rate Loans by giving the
Administrative Agent at least two Business Days' prior irrevocable notice of
such election, provided that any such conversion of Eurodollar Loans may be made
               --------
only on the last day of an Interest Period with respect thereto.  The Borrower
may elect from time to time to convert Base Rate Loans to Eurodollar Loans by
giving the Administrative Agent at least three Business Days' prior irrevocable
notice of such election (which notice shall specify the length of the initial
Interest Period therefor), provided that no Base Rate Loan under a particular
                           --------
Facility may be converted into a Eurodollar Loan (i) when any Event of Default
has occurred and is continuing and the Administrative Agent has, or the Majority
Facility Lenders in respect of such Facility have, determined in its or their
sole discretion not to permit such conversions or (ii) after the date that is
one month prior to the final scheduled termination or maturity date of such
Facility.  Upon

receipt of any such notice the Administrative Agent shall promptly notify each
relevant Lender thereof.

          (b)  The Borrower may elect to continue any Eurodollar Loan as such
upon the expiration of the then current Interest Period with respect thereto by
giving irrevocable notice to the Administrative Agent, in accordance with the
applicable provisions of the term "Interest Period" set forth in Section 1.1, of
the length of the next Interest Period to be applicable to such Loans, provided
                                                                       --------
that no Eurodollar Loan under a particular Facility may be continued as such (i)
when any Event of Default has occurred and is continuing and the Administrative
Agent has, or the Majority Facility Lenders in respect of such Facility have,
determined in its or their sole discretion not to permit such continuations or
(ii) after the date that is one month prior to the final scheduled termination
or maturity date of such Facility, and provided, further, that if the Borrower
                                       --------  -------
shall fail to give any required notice as described above in this paragraph or
if such continuation is not permitted pursuant to the preceding proviso, such
Loans shall be converted automatically to Base Rate Loans on the last day of
such then expiring Interest Period.  Upon receipt of any such notice the
Administrative Agent shall promptly notify each relevant Lender thereof.

          2.12  Minimum Amounts and Maximum Number of Eurodollar Tranches.
                ---------------------------------------------------------
Notwithstanding anything to the contrary in this Agreement, all borrowings,
conversions, continuations and optional prepayments of Eurodollar Loans and all
selections of Interest Periods shall be in such amounts and be made pursuant to
such elections so that, (a) after giving effect thereto, the aggregate principal
amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal
to $5,000,000 or a whole multiple of $1,000,000 in excess thereof and (b) no
more than ten Eurodollar Tranches shall be outstanding at any one time.

          2.13  Interest Rates and Payment Dates.  (a)  Each Eurodollar Loan
                --------------------------------
shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such day
plus the Applicable Margin.

          (b)   Each Base Rate Loan shall bear interest at a rate per annum
equal to the Base Rate plus the Applicable Margin.

          (c)   (i) If all or a portion of the principal amount of any Loan
shall not be paid when due (whether at the stated maturity, by acceleration or
otherwise), all outstanding Loans and Reimbursement Obligations (whether or not
overdue) shall bear interest at a rate per annum that is equal to (x) in the
case of the Loans, the rate that would otherwise be applicable thereto pursuant
to the foregoing provisions of this Section plus 2% or (y) in the case of

Reimbursement Obligations, the rate applicable to Base Rate Loans under the
Revolving Credit Facility plus 2%, and (ii) if all or a portion of any interest
                          ----
payable on any Loan or Reimbursement Obligation or any commitment fee or other
amount payable hereunder shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), such overdue amount shall bear interest
at a rate per annum equal to the rate then applicable to Base Rate Loans under
the relevant Facility plus 2% (or, in the case of any such other amounts that do
                      ----
not relate to a particular Facility, the rate then applicable to Base Rate Loans
under the Revolving Credit Facility plus 2%), in each

case, with respect to clauses (i) and (ii) above, from the date of such non-
payment until such amount is paid in full (after as well as before judgment).

          (d)  Interest shall be payable in arrears on each Interest Payment
Date, provided that interest accruing pursuant to paragraph (c) of this Section
      --------
shall be payable from time to time on demand.

          2.14  Computation of Interest and Fees.  (a)  Interest, fees,
                --------------------------------
commissions payable pursuant hereto shall be calculated on the basis of a 360-
day year for the actual days elapsed, except that, with respect to Base Rate
Loans on which interest is calculated on the basis of the Prime Rate, the
interest thereon shall be calculated on the basis of a 365- (or 366-, as the
case may be) day year for the actual days elapsed.  The Administrative Agent
shall as soon as practicable notify the Borrower and the relevant Lenders of
each determination of a Eurodollar Rate.  Any change in the interest rate on a
Loan resulting from a change in the Base Rate or the Eurocurrency Reserve
Requirements shall become effective as of the opening of business on the day on
which such change becomes effective.  The Administrative Agent shall as soon as
practicable notify the Borrower and the relevant Lenders of the effective date
and the amount of each such change in interest rate.

          (b)   Each determination of an interest rate by the Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrower and the Lenders in the absence of manifest error.  The
Administrative Agent shall, at the request of the Borrower, deliver to the
Borrower a statement showing the quotations used by the Administrative Agent in
determining any interest rate pursuant to Section 2.13(a).

          2.15  Inability to Determine Interest Rate.  If prior to the first day
                ------------------------------------
of any Interest Period:

          (a)   the Administrative Agent shall have determined (which
     determination shall be conclusive and binding upon the Borrower) that, by
     reason of circumstances affecting the relevant market, adequate and
     reasonable means do not exist for ascertaining the Eurodollar Rate for such
     Interest Period, or

          (b)   the Administrative Agent shall have received notice from the
     Majority Facility Lenders in respect of the relevant Facility that the
     Eurodollar Rate determined or to be determined for such Interest Period
     will not adequately and fairly reflect the cost to such Lenders (as
     conclusively certified by such Lenders) of making or maintaining their
     affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the relevant Lenders as soon as practicable thereafter.  If such
notice is given (x) any Eurodollar Loans under the relevant Facility requested
to be made on the first day of such Interest Period shall be made as Base Rate
Loans, (y) any Loans under the relevant Facility that were to have been
converted on the first day of such Interest Period to Eurodollar Loans shall be
continued as Base Rate Loans and (z) any outstanding Eurodollar Loans under the
relevant Facility shall be

converted, on the last day of the then current Interest Period with respect
thereto, to Base Rate Loans.  Until such notice has been withdrawn by the
Administrative Agent, no further Eurodollar Loans under the relevant Facility
shall be made or continued as such, nor shall the Borrower have the right to
convert Loans under the relevant Facility to Eurodollar Loans.

          2.16  Pro Rata Treatment and Payments.  (a)  Each borrowing by the
                -------------------------------
Borrower from the Lenders hereunder, each payment by the Borrower on account of
any commitment fee or Letter of Credit fee, and any reduction of the Commitments
of the Lenders, shall be made pro rata according to the respective Delayed Draw
                              --- ----
Term Loan Percentages, Tranche B Term Loan Percentages or Revolving Credit
Percentages, as the case may be, of the relevant Lenders.  Each payment (other
than prepayments) in respect of principal or interest in respect of the Loans
and each payment in respect of fees payable hereunder shall be applied to the
amounts of such obligations owing to the Lenders pro rata according to the
                                                 --- ----
respective amounts then due and owing to the Lenders.

          (b)  Each mandatory prepayment required by Section 2.10 to be applied
to Term Loans shall be allocated between the Term Loan Facilities pro rata

according to the respective outstanding principal amounts of Term Loans under
such Facilities.  Each optional prepayment in respect of the Term Loans shall be
allocated between the Term Loan Facilities pro rata according to the respective
                                           --- ----
outstanding principal amounts of Term Loans under such Facilities.  Each payment
(including each prepayment) of the Term Loans outstanding under any Term Loan
Facility shall be allocated among the Term Loan Lenders holding such Term Loans
pro rata based on the principal amount of such Term Loans held by such Term Loan
- --- ----
Lenders, and shall be applied to the installments of such Term Loans pro rata
                                                                     --- ----
based on the remaining outstanding principal amount of such installments.
Amounts prepaid on account of the Term Loans may not be reborrowed.

          (c)  Each payment (including each prepayment) by the Borrower on
account of principal of and interest on the Revolving Credit Loans shall be made
pro rata according to the respective outstanding principal amounts of the
- --- ----
Revolving Credit Loans then held by the Revolving Credit Lenders.  Each payment
in respect of outstanding Reimbursement Obligations in respect of any Letter of
Credit shall be made to the Issuing Lender that issued such Letters of Credit.

          (d)  Notwithstanding anything to the contrary in Sections 2.9, 2.10 or
2.16, so long as any Delayed Draw Term Loans are outstanding, each Tranche B
Term Loan Lender may, at its option, decline up to all or a portion of any
optional prepayment or mandatory payment applicable to the Tranche B Term Loans
of such Lender; accordingly, with respect to the amount of any optional
prepayment described in Section 2.9 or mandatory prepayment described in
Section 2.10, in each case that is allocated to Tranche B Term Loans (such
amounts, the "Tranche B Prepayment Amount"), at any time when Delayed Draw Term
              ---------------------------
Loans remain outstanding, the Borrower will, (i) in the case of any optional
prepayment which the Borrower wishes to make, not later than 10 Business Days
prior to the date on which the Borrower wishes to make such optional prepayment,

B Term Loans as provided in Section 2.10(e) and 2.16(b), on the date specified
in Section 2.10 for such prepayment, give the Administrative Agent telephonic
notice (promptly confirmed in writing) requesting that the Administrative Agent
prepare and provide to each Tranche B Term Loan Lender a notice (each, a
"Prepayment Option Notice") as described below.  As promptly as practicable
 ------------------------
after receiving such notice from the Borrower, the Administrative Agent will
send to each Tranche B Term Loan Lender (with a copy to the Borrower) a
Prepayment Option Notice, which shall be in the form of Exhibit H, and shall
include an offer by the Borrower to prepay on the date (each a "Prepayment
                                                                ----------

the relevant Tranche B Term Loans of such Lender by an amount equal to the
portion of the Prepayment Amount indicated in such Lender's Prepayment Option
Notice as being applicable to such Lender's Tranche B Term Loans.  On the
Prepayment Date, (i) the Borrower shall pay to the Administrative Agent the
aggregate amount necessary to prepay that portion of the outstanding relevant
Tranche B Term Loans in respect of which Tranche B Term Loan  Lenders have
accepted prepayment as described above (such Lenders, the "Accepting Lenders"),
                                                           -----------------
and such amount shall be applied toward prepayment of the Tranche B Term Loans
with respect to each Accepting Lender and (ii) the Borrower shall pay to the
Administrative Agent an amount equal to the portion of the Tranche B Prepayment
Amount not accepted by the Tranche B Term Loan Lenders, and such amount shall be
applied to the prepayment of the Delayed Draw Term Loans.

          (e)  All payments (including prepayments) to be made by the Borrower
hereunder, whether on account of principal, interest, fees or otherwise, shall
be made without setoff or counterclaim and shall be made prior to 1:00 pm, New
York City time, on the due date thereof to the Administrative Agent, for the
account of the Lenders, at the Payment Office, in Dollars and in immediately
available funds.  Any payment made by the Borrower after 1:00 pm, New York City
time, on any Business Day shall be deemed to have been on the next following
Business Day. The Administrative Agent shall distribute such payments to the
Lenders promptly upon receipt in like funds as received.  If any payment
hereunder (other than payments on the Eurodollar Loans) becomes due and payable
on a day other than a Business Day, such payment shall be extended to the next
succeeding Business Day.  If any payment on a Eurodollar Loan becomes due and
payable on a day other than a Business Day, the maturity thereof shall be
extended to the next succeeding Business Day unless the result of such extension
would be to extend such payment into another calendar month, in which event such
payment shall be made on the immediately preceding Business Day.  In the case of
any extension of any payment of principal pursuant to the preceding two
sentences, interest thereon shall be payable at the then applicable rate during
such extension.

          (f)  Unless the Administrative Agent shall have been notified in
writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its share of such borrowing available to the
Administrative Agent, the Administrative Agent may assume that such Lender is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrower a
corresponding amount.  If such amount is not made available to the
Administrative Agent by the required time on the Borrowing Date therefor, such
Lender shall pay to the Administrative Agent, on demand, such amount with
interest thereon at a rate equal to the daily average Federal
<PAGE>

                                                                              36

Funds Effective Rate for the period until such Lender makes such amount
immediately available to the Administrative Agent.  A certificate of the
Administrative Agent submitted to any Lender with respect to any amounts owing
under this paragraph shall be conclusive in the absence of manifest error.  If
such Lender's share of such borrowing is not made available to the
Administrative Agent by such Lender within three Business Days after such
Borrowing Date, the Administrative Agent shall also be entitled to recover such
amount with interest thereon at the rate per annum applicable to Base Rate Loans
under the relevant Facility, on demand, from the Borrower.

          (g)  Unless the Administrative Agent shall have been notified in
writing by the Borrower prior to the date of any payment due to be made by the
Borrower hereunder that the Borrower will not make such payment to the
Administrative Agent, the Administrative Agent may assume that the Borrower is
making such payment, and the Administrative Agent may, but shall not be required
to, in reliance upon such assumption, make available to the Lenders their
respective pro rata shares of a corresponding amount.  If such payment is not
           --- ----
made to the Administrative Agent by the Borrower within three Business Days
after such due date, the Administrative Agent shall be entitled to recover, on
demand, from each Lender to which any amount which was made available pursuant
to the preceding sentence, such amount with interest thereon at the rate per
annum equal to the daily average Federal Funds Effective Rate.  Nothing herein
shall be deemed to limit the rights of the Administrative Agent or any Lender
against the Borrower.

          2.17  Requirements of Law.  (a)  If the adoption of or any change in
                -------------------
any Requirement of Law or in the interpretation or application thereof or
compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority made
subsequent to the date hereof:

          (i)   shall subject any Lender to any tax of any kind whatsoever
     with respect to this Agreement, any Letter of Credit, any Application or
     any Eurodollar Loan made by it, or change the basis of taxation of payments
     to such Lender in respect thereof (except for Non-Excluded Taxes covered by
     Section 2.18 and changes in the rate of tax on the overall net income of
     such Lender);

          (ii)  shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender that is not otherwise included in the determination
     of the Eurodollar Rate hereunder; or

          (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or issuing or participating in
Letters of Credit, or to reduce any amount receivable hereunder in respect
thereof, then, in any such case, the Borrower shall pay such
<PAGE>

                                                                              37

Lender, within 30 days following its demand, any additional amounts necessary to
compensate such Lender for such increased cost or reduced amount receivable. If
any Lender becomes entitled to claim any additional amounts pursuant to this
Section, it shall promptly notify the Borrower (with a copy to the
Administrative Agent) of the event by reason of which it has become so entitled.

          (b)  If any Lender shall have determined that the adoption of or any
change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under or in respect of any Letter of
Credit to a level below that which such Lender or such corporation could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or such corporation's policies with respect to capital adequacy)
by an amount deemed by such Lender to be material, then from time to time,
within 30 days following submission by such Lender to the Borrower (with a copy
to the Administrative Agent) of a written request therefor, the Borrower shall
pay to such Lender such additional amount or amounts as will compensate such
Lender or such corporation for such reduction.

          (c)  A certificate as to any additional amounts payable pursuant to
this Section submitted by any Lender to the Borrower (with a copy to the
Administrative Agent), together with an explanation and accompanying
calculations in reasonable detail, shall be conclusive in the absence of
manifest error.  The obligations of the Borrower pursuant to this Section shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder.

          2.18  Taxes.  (a)  All payments made by the Borrower under this
                -----
Agreement shall be made free and clear of, and without deduction or withholding
for or on account of, any present or future income, stamp or other taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, now or
hereafter imposed, levied, collected, withheld or assessed by any Governmental
Authority, excluding net income taxes and franchise taxes (imposed in lieu of
net income taxes) imposed on any Agent or any Lender as a result of a present or
former connection between such Agent or such Lender and the jurisdiction of the
Governmental Authority imposing such tax or any political subdivision or taxing
authority thereof or therein (other than any such connection arising solely from
such Agent's or such Lender's having executed, delivered or performed its
obligations or received a payment under, or enforced, this Agreement or any
other Loan Document).  If any such non-excluded taxes, levies, imposts, duties,
charges, fees, deductions or withholdings ("Non-Excluded Taxes") or any Other
                                            ------------------
Taxes are required to be withheld from any amounts payable to any Agent or any
Lender hereunder, the amounts so payable to such Agent or such Lender shall be
increased to the extent necessary to yield to such Agent or such Lender (after
payment of all Non-Excluded Taxes and Other Taxes) interest or any such other
amounts payable hereunder at the rates or in the amounts specified in this
Agreement; provided, however, that the Borrower shall not be required to
           --------  -------
increase any such amounts payable to any Lender with respect to any Non-Excluded
Taxes (i) that are attributable to such Lender's
<PAGE>

                                                                              38

failure to comply with the requirements of paragraph (d) or (e) of this Section
or (ii) that are United States withholding taxes imposed on amounts payable to
such Lender at the time such Lender becomes a party to this Agreement, except to
the extent that such Lender's assignor (if any) was entitled, at the time of
assignment, to receive additional amounts from the Borrower with respect to such
Non-Excluded Taxes pursuant to Section 2.18(a).

          (b)  In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

          (c)  Whenever any Non-Excluded Taxes or Other Taxes are payable by the
Borrower, as promptly as possible thereafter the Borrower shall send to the
Administrative Agent for the account of the relevant Agent or Lender, as the
case may be, a certified copy of an original official receipt received by the
Borrower showing payment thereof.  If the Borrower fails to pay any Non-Excluded
Taxes or Other Taxes when due to the appropriate taxing authority or fails to
remit to the Administrative Agent the required receipts or other required
documentary evidence, the Borrower shall indemnify the Agents and the Lenders
for any incremental taxes, interest or penalties that become payable by any
Agent or any Lender as a result of any such failure.  The agreements in this
Section 2.18 shall survive the termination of this Agreement and the payment of
the Loans and all other amounts payable hereunder.

          (d)  Each Lender (or Transferee) that is not a citizen or resident of
the United States of America, a corporation, partnership or other entity created
or organized in or under the laws of the United States of America (or any
jurisdiction thereof), or any estate or trust that is subject to federal income
taxation regardless of the source of its income (a "Non-U.S. Lender") shall
                                                    ---------------
deliver to the Borrower and the Administrative Agent (or, in the case of a
Participant, to the Lender from which the related participation shall have been
purchased) two copies of either U.S. Internal Revenue Service Form 1001 or Form
4224 (or, if required, Form W-8BEN or Form W-8ECI), or, in the case of a Non-
U.S. Lender claiming exemption from U.S. federal withholding tax under Section
871(h) or 881(c) of the Code with respect to payments of "portfolio interest" a
statement substantially in the form of Exhibit G and a Form W-8, or any
subsequent versions thereof or successors thereto properly completed and duly
executed by such Non-U.S. Lender claiming complete exemption from U.S. federal
withholding tax on all payments by the Borrower under this Agreement and the
other Loan Documents.  Such forms shall be delivered by each Non-U.S. Lender on
or before the date it becomes a party to this Agreement (or, in the case of any
Participant, on or before the date such Participant purchases the related
participation).  In addition, each Non-U.S. Lender shall deliver such forms
promptly upon the obsolescence or invalidity of any form previously delivered by
such Non-U.S. Lender.  Each Non-U.S. Lender shall promptly notify the Borrower
at any time it determines that it is no longer in a position to provide any
previously delivered certificate to the Borrower (or any other form of
certification adopted by the U.S. taxing authorities for such purpose).
Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall
not be required to deliver any form pursuant to this paragraph that such Non-
U.S. Lender is not legally able to deliver.

          (e)  A Lender that is entitled to an exemption from non-U.S.
withholding tax under the law of the jurisdiction in which the Borrower is
located, or any treaty to which such
<PAGE>

                                                                              39

jurisdiction is a party, with respect to payments under this Agreement shall
deliver to the Borrower (with a copy to the Administrative Agent), at the time
or times prescribed by applicable law or reasonably requested by the Borrower,
such properly completed and executed documentation prescribed by applicable law
as will permit such payments to be made without withholding, provided that such
                                                             --------
Lender is legally entitled to complete, execute and deliver such documentation
and in such Lender's reasonable judgment such completion, execution or
submission would not materially prejudice the legal position of such Lender.

          (f)   No Lender shall be subject to U.S withholding tax or non-U.S.
withholding tax on the date it becomes a party to this Agreement (or, in the
case of any Participant, on the date such Participant purchases the related
participation).

          2.19  Indemnity.  The Borrower agrees to indemnify each Lender for,
                ---------
and to hold each Lender harmless from, any loss or expense that such Lender may
sustain or incur as a consequence of (a) default by the Borrower in making a
borrowing of, conversion into or continuation of Eurodollar Loans after the
Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (b) subject to Section 2.16(d), default by the
Borrower in making any prepayment after the Borrower has given a notice thereof
in accordance with the provisions of this Agreement or (c) subject to Section
2.16(d), the making of a prepayment or conversion of Eurodollar Loans on a day
that is not the last day of an Interest Period with respect thereto.  Such
indemnification may include an amount equal to the excess, if any, of (i) the
amount of interest that would have accrued on the amount so prepaid, or not so
borrowed, converted or continued, for the period from the date of such
prepayment or of such failure to borrow, convert or continue to the last day of
such Interest Period (or, in the case of a failure to borrow, convert or
continue, the Interest Period that would have commenced on the date of such
failure) in each case at the applicable rate of interest for such Loans provided
for herein (excluding, however, the Applicable Margin included therein, if any)
over (ii) the amount of interest (as reasonably determined by such Lender) that
- ----
would have accrued to such Lender on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank Eurodollar
market.  A certificate as to any amounts payable pursuant to this Section
submitted to the Borrower by any Lender shall be conclusive in the absence of
manifest error.  This covenant shall survive the termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder.

          2.20  Illegality.  Notwithstanding any other provision herein, if
                ----------
after the date hereof the adoption of or any change in any Requirement of Law or
in the interpretation or application thereof shall make it unlawful for any
Lender to make or maintain Eurodollar Loans as contemplated by this Agreement,
(a) the commitment of such Lender hereunder to make Eurodollar Loans, continue
Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall
forthwith be canceled and (b) such Lender's Loans then outstanding as Eurodollar
Loans, if any, shall be converted automatically to Base Rate Loans on the
respective last days of the then current Interest Periods with respect to such
Loans or within such earlier period as required by law.  If any such conversion
of a Eurodollar Loan occurs on a day which is not the last day of the then
current Interest Period with respect thereto, the Borrower shall pay to such
Lender such amounts, if any, as may be required pursuant to Section 2.19.

          2.21  Change of Lending Office.  Each Lender agrees that, upon the
                ------------------------
occurrence of any event giving rise to the operation of Section 2.17, 2.18(a) or
2.20 with respect to such Lender, it will, if requested by the Borrower, use
reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans affected by such event with the
object of avoiding the consequences of such event; provided, that such
                                                   --------
designation is made on terms that, in the sole judgment of such Lender, cause
such Lender and its lending office(s) to suffer no economic, legal or regulatory
disadvantage, and provided, further, that nothing in this Section shall affect
                  --------  -------
or postpone any of the obligations of any Borrower or the rights of any Lender
pursuant to Section 2.17, 2.18(a) or 2.20.

          2.22  Replacement of Lenders under Certain Circumstances.  The
                --------------------------------------------------
Borrower shall be permitted to replace any Lender that (a) requests
reimbursement for amounts owing pursuant to Section 2.17 or 2.18 or (b) defaults
in its obligation to make Loans hereunder, with a replacement financial
institution; provided that (i) such replacement does not conflict with any
             --------
Requirement of Law, (ii) no Event of Default shall have occurred and be
continuing at the time of such replacement, (iii) prior to any such replacement,
such Lender shall have taken each required action under Section 2.21 so as to
eliminate the continued need for payment of amounts owing pursuant to Section
2.17 or 2.18, (iv) the replacement financial institution shall purchase, at par,
all Loans and other amounts owing to such replaced Lender on or prior to the
date of replacement, (v) the Borrower shall be liable to such replaced Lender
under Section 2.19 (as though Section 2.19 were applicable) if any Eurodollar
Loan owing to such replaced Lender shall be purchased other than on the last day
of the Interest Period relating thereto, (vi) the replacement financial
institution, if not already a Lender, shall be reasonably satisfactory to the
Administrative Agent, (vii)  the replaced Lender shall be obligated to make such
replacement in accordance with the provisions of Section 10.6 (provided that the
Borrower or such replacement financial institution shall be obligated to pay the
registration and processing fee referred to therein), (viii) the Borrower shall
pay all additional amounts (if any) required pursuant to Section 2.17 or 2.18,
as the case may be, in respect of any period prior to the date on which such
replacement shall be consummated, and (ix) any such replacement shall not be
deemed to be a waiver of any rights that the Borrower, any Agent or any other
Lender shall have against the replaced Lender.


                         SECTION 3.  LETTERS OF CREDIT

          3.1  L/C Commitment.  (a)  Subject to the terms and conditions hereof,
               --------------
each Issuing Lender, in reliance on the agreements of the other Revolving Credit
Lenders set forth in Section 3.4(a), agrees to issue letters of credit ("Letters
                                                                         -------
of Credit") for the account of the Borrower (or for the joint and several
- ---------
account of the Borrower and any Domestic Subsidiary thereof, if so requested by
the Borrower) on any Business Day during the Revolving Credit Commitment Period
in such form as may be approved from time to time by such Issuing Lender;
provided, that no Issuing Lender shall have any obligation to issue any Letter
- --------
of Credit if, after giving effect to such issuance, (i) the L/C Obligations
would exceed the L/C Commitment or (ii) the aggregate amount of the Available
Revolving Credit Commitments would be less than zero.
<PAGE>

                                                                              41



Each Letter of Credit shall (i) be denominated in Dollars and (ii) expire no
later than the earlier of (x) the first anniversary of its date of issuance and
(y) the date which is five Business Days prior to the Scheduled Revolving Credit
Termination Date, provided that any Letter of Credit with a one-year term may
                  --------
provide for the renewal thereof for additional one-year periods (which shall in
no event extend beyond the date referred to in clause (y) above).

          (b)  No Issuing Lender shall at any time be obligated to issue any
Letter of Credit hereunder if such issuance would conflict with, or cause such
Issuing Lender or any L/C Participant to exceed any limits imposed by, any
applicable Requirement of Law.

          3.2  Procedure for Issuance of Letter of Credit.  The Borrower may
               ------------------------------------------
from time to time request that an Issuing Lender issue a Letter of Credit by
delivering to such Issuing Lender at its address for notices specified herein an
Application therefor, completed to the reasonable satisfaction of such Issuing
Lender, and such other certificates, documents and other papers and information
as such Issuing Lender may reasonably request.  Upon receipt of any Application,
an Issuing Lender will process such Application and the certificates, documents
and other papers and information delivered to it in connection therewith in
accordance with its customary procedures and shall promptly issue the Letter of
Credit requested thereby by issuing the original of such Letter of Credit to the
beneficiary thereof or as otherwise may be agreed to by such Issuing Lender and
the Borrower (but in no event shall any Issuing Lender be required to issue any
Letter of Credit earlier than three Business Days after its receipt of the
Application therefor and all such other certificates, documents and other papers
and information relating thereto).  Promptly after issuance by an Issuing Lender
of a Letter of Credit, such  Issuing Lender shall furnish a copy of such Letter
of Credit to the Borrower.  Each Issuing Lender shall promptly furnish to the
Administrative Agent, notice of the issuance of each Letter of Credit issued by
it (including the amount thereof).

          3.3  Fees and Other Charges.  (a)  The Borrower will pay a fee on the
               ----------------------
aggregate drawable amount of each outstanding Letter of Credit at a per annum
rate equal to the Applicable Margin then in effect with respect to Eurodollar
Loans under the Revolving Credit Facility, shared ratably among the Revolving
Credit Lenders in accordance with their respective Revolving Credit Percentages
and payable quarterly in arrears on each L/C Fee Payment Date after the issuance
date of such Letter of Credit.  In addition, the Borrower shall pay to the
relevant Issuing Lender for its own account a fronting fee on the aggregate
drawable amount of each outstanding Letter of Credit issued by it at a rate per
annum to be agreed upon by the Borrower and the Issuing Lender, payable
quarterly in arrears on each L/C Fee Payment Date after the issuance date of
such Letter of Credit.

          (b)  In addition to the foregoing fees, the Borrower shall pay or
reimburse each Issuing Lender for such normal and customary costs and expenses
as are incurred or charged by the Issuing Lender in issuing, negotiating,
effecting payment under, amending or otherwise administering any Letter of
Credit.

          3.4  L/C Participations.  (a)  Each Issuing Lender irrevocably agrees
               ------------------
to grant and hereby grants to each L/C Participant, and, to induce each Issuing
Lender to issue Letters of
<PAGE>

                                                                              42

Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase
and hereby accepts and purchases from each Issuing Lender, on the terms and
conditions hereinafter stated, for such L/C Participant's own account and risk
an undivided interest equal to such L/C Participant's Revolving Credit
Percentage in each Issuing Lender's obligations and rights under each Letter of
Credit issued by such Issuing Lender hereunder and the amount of each draft paid
by such Issuing Lender thereunder. Each L/C Participant unconditionally and
irrevocably agrees with each Issuing Lender that, if a draft is paid under any
Letter of Credit issued by such Issuing Lender for which such Issuing Lender is
not reimbursed in full by the Borrower in accordance with the terms of this
Agreement, such L/C Participant shall pay to such Issuing Lender upon demand at
such Issuing Lender's address for notices specified herein an amount equal to
such L/C Participant's Revolving Credit Percentage of the amount of such draft,
or any part thereof, that is not so reimbursed.

          (b)  If any amount required to be paid by any L/C Participant to an
Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion
of any payment made by such Issuing Lender under any Letter of Credit is paid to
such Issuing Lender within three Business Days after the date such payment is
due, such L/C Participant shall pay to such Issuing Lender on demand an amount
equal to the product of (i) such amount, times (ii) the daily average Federal
Funds Effective Rate during the period from and including the date such payment
is required to the date on which such payment is immediately available to such
Issuing Lender, times (iii) a fraction the numerator of which is the number of
days that elapse during such period and the denominator of which is 360.  If any
such amount required to be paid by any L/C Participant pursuant to Section
3.4(a) is not made available to such Issuing Lender by such L/C Participant
within three Business Days after the date such payment is due, such Issuing
Lender shall be entitled to recover from such L/C Participant, on demand, such
amount with interest thereon calculated from such due date at the rate per annum
applicable to Base Rate Loans under the Revolving Credit Facility.  A
certificate of such Issuing Lender submitted to any L/C Participant with respect
to any such amounts owing under this Section shall be conclusive in the absence
of manifest error.

          (c)  Whenever, at any time after an Issuing Lender has made payment
under any Letter of Credit and has received from any L/C Participant its pro
                                                                         ---
rata share of such payment in accordance with Section 3.4(a), such Issuing
- ----
Lender receives any payment related to such Letter of Credit (whether directly
from the Borrower or otherwise, including proceeds of collateral applied thereto
by such Issuing Lender), or any payment of interest on account thereof, such
Issuing Lender will distribute to such L/C Participant its pro rata share
                                                           --- ----
thereof; provided, however, that in the event that any such payment received by
         --------  -------
such Issuing Lender shall be required to be returned by such Issuing Lender,
such L/C Participant shall return to such Issuing Lender the portion thereof
previously distributed by such Issuing Lender to it.

          3.5  Reimbursement Obligation of the Borrower.  The Borrower agrees to
               ----------------------------------------
reimburse each Issuing Lender on the next Business Day after each date on which
such Issuing Lender notifies the Borrower of the date and amount of a draft
presented under any Letter of Credit and paid by such Issuing Lender for the
amount of (a) such draft so paid and (b) any taxes, fees, charges or other costs
or expenses incurred by such Issuing Lender in connection with such
<PAGE>

                                                                              43

payment (the amounts described in the foregoing clauses (a) and (b) in respect
of any drawing, collectively, the "Payment Amount"). Each such payment shall be
                                   --------------
made to such Issuing Lender at its address for notices specified herein in
lawful money of the United States of America and in immediately available funds.
Interest shall be payable on each Payment Amount from the date of the applicable
drawing until payment in full at the rate set forth in (i) until the second
Business Day following the date of the applicable drawing, Section 2.13(b) and
(ii) thereafter, Section 2.13(c). Each drawing under any Letter of Credit shall
(unless an event of the type described in clause (i) or (ii) of Section 8(f)
shall have occurred and be continuing with respect to the Borrower, in which
case the procedures specified in Section 3.4 for funding by L/C Participants
shall apply) constitute a request by the Borrower to the Administrative Agent
for a borrowing pursuant to Section 2.5 of Base Rate Loans in the amount of such
drawing. The Borrowing Date with respect to such borrowing shall be the first
date on which a borrowing of Revolving Credit Loans could be made (without
regard to whether the conditions precedent in Section 5.2 are satisfied),
pursuant to Section 2.5, if the Administrative Agent had received a notice of
such borrowing at the time the Administrative Agent receives notice from the
relevant Issuing Lender of such drawing under such Letter of Credit.

          3.6  Obligations Absolute.  The Borrower's obligations under this
               --------------------
Section 3 shall be absolute and unconditional under any and all circumstances
and irrespective of any setoff, counterclaim or defense to payment that the
Borrower may have or have had against any Issuing Lender, any beneficiary of a
Letter of Credit or any other Person.  The Borrower also agrees with each
Issuing Lender that such Issuing Lender shall not be responsible for, and the
Borrower's Reimbursement Obligations under Section 3.5 shall not be affected by,
among other things, the validity or genuineness of documents or of any
endorsements thereon, even though such documents shall in fact prove to be
invalid, fraudulent or forged, or any dispute between or among the Borrower and
any beneficiary of any Letter of Credit or any other party to which such Letter
of Credit may be transferred or any claims whatsoever of the Borrower against
any beneficiary of such Letter of Credit or any such transferee.  No Issuing
Lender shall be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except for errors or
omissions resulting from the gross negligence or willful misconduct of such
Issuing Lender.  The Borrower agrees that any action taken or omitted by an
Issuing Lender under or in connection with any Letter of Credit issued by it or
the related drafts or documents, if done in the absence of gross negligence or
willful misconduct and in accordance with the standards of care specified in the
Uniform Commercial Code of the State of New York, shall be binding on the
Borrower and shall not result in any liability of such Issuing Lender to the
Borrower.

          3.7  Letter of Credit Payments.  If any draft shall be presented for
               -------------------------
payment under any Letter of Credit, the relevant Issuing Lender shall promptly
notify the Borrower of the date and amount thereof.  The responsibility of the
relevant Issuing Lender to the Borrower in connection with any draft presented
for payment under any Letter of Credit shall, in addition to any payment
obligation expressly provided for in such Letter of Credit issued by such
Issuing Lender, be limited to determining that the documents (including each
draft) delivered under such Letter of Credit in connection with such presentment
are substantially in conformity with such Letter of Credit.

          3.8  Applications.  To the extent that any provision of any
               ------------
Application related to any Letter of Credit is inconsistent with the provisions
of this Section 3, the provisions of this Section 3 shall apply.


                  SECTION 4.  REPRESENTATIONS AND WARRANTIES

          To induce the Agents and the Lenders to enter into this Agreement and
to make the Loans, the Borrower hereby represents and warrants to each Agent and
each Lender that:

          4.1  Financial Condition.  (a)  The audited consolidated balance
               -------------------
sheets of the Borrower as at April 2, 1999 and the related consolidated
statements of income and of cash flows for the fiscal year ended on such dates,
reported on by and accompanied by an unqualified report from Deloitte & Touche,
present fairly the consolidated financial condition of the Borrower as at such
date, and the consolidated results of its operations and its consolidated cash
flows for the fiscal year then ended.  The pro forma unaudited consolidated
balance sheet of the Borrower (excluding NTC) as at April 2, 1999, and the
related unaudited consolidated statements of income and cash flows for the
twelve-month period ended on such date, present fairly the consolidated
financial condition of the Borrower as at such date, and the consolidated
results of its operations and its consolidated cash flows for the twelve-month
period then ended (subject to normal year-end audit adjustments)(excluding NTC).
All such financial statements, including the related schedules and notes
thereto, have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by the aforementioned firm
of accountants and disclosed therein).  The Borrower and its Subsidiaries do not
have any material Guarantee Obligations, contingent liabilities and liabilities
for taxes, or any long-term leases or unusual forward or long-term commitments,
including, without limitation, any interest rate or foreign currency swap or
exchange transaction or other obligation in respect of derivatives, that are not
reflected in the most recent financial statements referred to in this paragraph.
During the period from April 2, 1999 to and including the date hereof there has
been no Disposition by the Borrower or any of its Subsidiaries of any material
part of their business or Property.

          4.2  No Change.  Since April 2, 1999 there has been no development or

corporate power and authority, and the legal right, to own and operate its
Property, to lease the Property it operates as lessee and to conduct the
business in which it is currently engaged, (c) is duly qualified as a foreign
corporation and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of Property or the conduct of its business
requires such qualification except where failure to be so qualified or in good
standing could not reasonably be expected to have a Material Adverse Effect
<PAGE>

                                                                              45

and (d) is in compliance with all Requirements of Law except to the extent that
the failure to comply therewith could not, in the aggregate, reasonably be
expected to have a Material Adverse Effect.

          4.4  Corporate Power; Authorization; Enforceable Obligations.  Each
               -------------------------------------------------------
Loan Party has the corporate power and authority, and the legal right, to make,
deliver and perform the Loan Documents to which it is a party and, in the case
of the Borrower, to borrow hereunder.  Each Loan Party has taken all necessary
corporate or other action to authorize the execution, delivery and performance
of the Loan Documents to which it is a party and, in the case of the Borrower,
to authorize the borrowings on the terms and conditions of this Agreement.  No
consent or authorization of, filing with, notice to or other act by or in
respect of, any Governmental Authority or any other Person is required in
connection with the borrowings hereunder or the execution, delivery,
performance, validity or enforceability of this Agreement or any of the other
Loan Documents, except (i) approvals by the board of directors or other
governing body and such consents, authorizations, filings and notices described
in Schedule 4.4, which approvals, consents, authorizations, filings and notices
have been obtained or made and are in full force and effect, (ii) the filings
referred to in Section 4.22 and (iii) such approvals, consents, authorizations,
filings and notices the absence of which could not reasonably be expected to
have a Material Adverse Effect.  This Agreement has been, and each other Loan
Document when executed and delivered pursuant hereto will have been, duly
executed and delivered on behalf of each Loan Party that is a party thereto.
This Agreement constitutes, and each other Loan Document upon execution will
constitute, a legal, valid and binding obligation of each Loan Party that is a
party thereto, enforceable against each such Loan Party in accordance with its
terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement
of creditors' rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

          4.5  No Legal Bar.  The execution, delivery and performance of this
               ------------
Agreement and the other Loan Documents, the issuance of Letters of Credit, the
borrowings hereunder and the use of the proceeds thereof will not violate any
Requirement of Law or any Contractual Obligation of  the Borrower or any of its
Subsidiaries in any respect that could reasonably be expected to have a Material
Adverse Effect and will not result in, or require, the creation or imposition of
any Lien on any of their respective properties or revenues pursuant to any
Requirement of Law or any such Contractual Obligation (other than the Liens
created by the Security Documents).

          4.6  No Material Litigation.  No litigation, investigation or
               ----------------------
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of the Borrower, threatened by or against the Borrower or any
of its Subsidiaries or against any of their respective properties or revenues
(a) with respect to any of the Loan Documents or any of the transactions
contemplated hereby or thereby, or (b) that could reasonably be expected to have
a Material Adverse Effect.

          4.7  No Default.  Neither  the Borrower nor any of its Subsidiaries is
               ----------
in default under or with respect to any of its Contractual Obligations in any
respect that could reasonably
<PAGE>

                                                                              46

be expected to have a Material Adverse Effect. No Default or Event of Default
has occurred and is continuing.

          4.8   Ownership of Property; Liens.  Each of  the Borrower and its
                ----------------------------
Subsidiaries has title in fee simple to, or a valid leasehold interest in, all
its real property, and good title to, or a valid leasehold interest in, all its
other Property, and none of such Property is subject to any Lien except as
permitted by Section 7.3.  The Borrower and its Subsidiaries have all material
rights of way and permits required to use communications lines or facilities
required for the conduct of their business.

          4.9   Intellectual Property.  The Borrower and each of its
                ---------------------
Subsidiaries owns, or is licensed to use, all Intellectual Property necessary
for the conduct of its business as currently conducted. No material claim has
been asserted and is pending by any Person challenging or questioning the use by
the Borrower or any of its Subsidiaries of any material Intellectual Property or
the validity or effectiveness of any material Intellectual Property owned by the
Borrower or any of its Subsidiaries, nor does the Borrower know of any valid
basis for any such claim. The use of material Intellectual Property by the
Borrower and its Subsidiaries does not infringe on the rights of any Person in
any material respect.

          4.10  Taxes.  Each of  the Borrower and each of its Subsidiaries has
                -----
filed or caused to be filed all Federal, state and other material tax returns
that are required to be filed and has paid all taxes shown to be due and payable
on said returns or on any assessments made against it or any of its Property and
all other material taxes, fees or other charges imposed on it or any of its
Property by any Governmental Authority (other than any the amount or validity of
which are currently being contested in good faith by appropriate proceedings and
with respect to which reserves in conformity with GAAP have been provided on the
books of the Borrower or its Subsidiaries, as the case may be); and no tax Lien
has been filed, and, to the knowledge of the Borrower, no claim is being
asserted, with respect to any such material tax, fee or other charge.

          4.11  Federal Regulations.  No part of the proceeds of any Revolving
                -------------------
Credit Loans will be used for "purchasing" or "carrying" any "margin stock"
within the respective meanings of each of the quoted terms under Regulation U as
now and from time to time hereafter in effect or for any purpose that violates
the provisions of the Regulations of the Board.  If requested by any Lender or
the Administrative Agent, the Borrower will furnish to the Administrative Agent
and each Lender a statement to the foregoing effect in conformity with the
requirements of FR Form G-3 or FR Form U-1 referred to in Regulation U.

          4.12  Labor Matters. There are no strikes or other labor disputes
                -------------
against the Borrower or any of its Subsidiaries pending or, to the knowledge of
the Borrower, threatened that (individually or in the aggregate) could
reasonably be expected to have a Material Adverse Effect.  Hours worked by and
payment made to employees of  the Borrower and its Subsidiaries have not been in
violation of the Fair Labor Standards Act or any other applicable Requirement of
Law dealing with such matters that (individually or in the aggregate) could
reasonably be expected to have a Material Adverse Effect.  All payments due from
the Borrower or any of its Subsidiaries on account of employee health and
welfare insurance that (individually or in the
<PAGE>

                                                                              47

aggregate) could reasonably be expected to have a Material Adverse Effect if not
paid have been paid or accrued as a liability on the books of the Borrower or
the relevant Subsidiary.

          4.13  ERISA.  Neither a Reportable Event nor an "accumulated funding
                -----
deficiency" (within the meaning of Section 412 of the Code or Section 302 of
ERISA) has occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code.  No termination of a Single Employer Plan has occurred, and no
Lien in favor of the PBGC or a Plan has arisen, during such five-year period.
The present value of all accrued benefits under each Single Employer Plan (based
on those assumptions used to fund such Plans) did not, as of the last annual
valuation date prior to the date on which this representation is made or deemed
made, exceed the value of the assets of such Plan allocable to such accrued
benefits by a material amount.  Neither the Borrower nor any Commonly Controlled
Entity has had a complete or partial withdrawal from any Multiemployer Plan that
has resulted or could reasonably be expected to result in a material liability
under ERISA, and neither the Borrower nor any Commonly Controlled Entity would
become subject to any material liability under ERISA if the Borrower or any such
Commonly Controlled Entity were to withdraw completely from all Multiemployer
Plans as of the valuation date most closely preceding the date on which this
representation is made or deemed made.  No such Multiemployer Plan is in
Reorganization or Insolvent.

          4.14  Investment Company Act; Other Regulations.  No Loan Party is an
                -----------------------------------------
"investment company", or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended.  No Loan
Party is subject to regulation under any Requirement of Law (other than
Regulation X of the Board) which limits its ability to incur Indebtedness.

          4.15  Subsidiaries.  (a) The Subsidiaries listed on Schedule 4.15
                ------------
constitute all the Subsidiaries of the Borrower at the date hereof.  Schedule
4.15 sets forth as of the Closing Date the name and jurisdiction of
incorporation of each Subsidiary and, as to each Subsidiary, the percentage of
each class of Capital Stock owned by each Loan Party.

          (b)  As of the Closing Date, there are no outstanding subscriptions,
options, warrants, calls, rights or other agreements or commitments (other than
stock options granted to employees or directors and directors' qualifying
shares) of any nature relating to any Capital Stock of  any Subsidiary, except
as disclosed on Schedule 4.15.

          4.16  Use of Proceeds.   The proceeds of the Tranche B Term Loans and
                ---------------
a portion of the proceeds of the Delayed Draw Term Loans shall be used to repay
the Existing Credit Facilities.  The proceeds of the Delayed Draw Term Loans and
the Revolving Credit Loans shall be used for the general working capital needs
of the Borrower and its Subsidiaries, including Capital Expenditures and a loan
from the Borrower to NTC in an aggregate principal amount not to exceed
$5,000,000.

          4.17  Environmental Matters.  Other than exceptions to any of the
                ---------------------
following that could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect:

          (a)  the Borrower and its Subsidiaries:  (i) are, and within the
     period of all applicable statutes of limitation have been, in compliance
     with all applicable Environmental Laws; (ii) hold all Environmental Permits
     (each of which is in full force and effect) required for any of their
     current or intended operations or for any property owned, leased, or
     otherwise operated by any of them; (iii) are, and within the period of all
     applicable statutes of limitation have been, in compliance with all of
     their Environmental Permits; and (iv) reasonably believe that:  each of
     their Environmental Permits will be timely renewed and complied with,
     without material expense; any additional Environmental Permits that may be
     required of any of them will be timely obtained and complied with, without
     material expense; and compliance with any Environmental Law that is or is
     expected to become applicable to any of them will be timely attained and
     maintained, without material expense.

          (b)  Materials of Environmental Concern are not present at, on, under,
     in, or about any real property now or formerly owned, leased or operated by
     the Borrower or any of its Subsidiaries, or at any other location
     (including, without limitation, any location to which Materials of
     Environmental Concern have been sent for re-use or recycling or for
     treatment, storage, or disposal) which could reasonably be expected to (i)
     give rise to liability of the Borrower or any of its Subsidiaries under any
     applicable Environmental Law or otherwise result in costs to the Borrower
     or any of its Subsidiaries, or (ii) interfere with the Borrower's or any of
     its Subsidiaries' continued operations, or (iii) impair the fair saleable
     value of any real property owned by the Borrower or any of its
     Subsidiaries.

          (c)  There is no judicial, administrative, or arbitral proceeding
     (including any notice of violation or alleged violation) under or relating
     to any Environmental Law to which the Borrower or any of its Subsidiaries
     is, or to the knowledge of the Borrower or will be, named as a party that
     is pending or, to the knowledge of the Borrower, threatened.

          (d)  Neither the Borrower nor any of its Subsidiaries has received any
     written request for information, or been notified that it is a potentially
     responsible party under or relating to the federal Comprehensive
     Environmental Response, Compensation, and Liability Act or any similar
     Environmental Law, or with respect to any Materials of Environmental
     Concern.

          (e)  Neither the Borrower nor any of its Subsidiaries has entered into
     or agreed to any consent decree, order, or settlement or other agreement,
     or is subject to any judgment, decree, or order or other agreement, in any
     judicial, administrative, arbitral, or other forum for dispute resolution,
     relating to compliance with or liability under any Environmental Law.

          (f)  Neither the Borrower nor any of its Subsidiaries has assumed or
     retained, by contract or operation of law, any liabilities of any kind,
     fixed or contingent, known or unknown, under any Environmental Law or with
     respect to any Material of Environmental Concern.

          4.18  Accuracy of Information, etc.  No factual statement or
                -----------------------------
information contained in this Agreement, any other Loan Document, the
Confidential Information Memorandum or any other document, certificate or
statement furnished in writing to the Administrative Agent or the Lenders or any
of them, by or on behalf of any Loan Party for use in connection with the
transactions contemplated by this Agreement or the other Loan Documents,
contained as of the date such statement, information, document or certificate
was so furnished (or, in the case of the Confidential Information Memorandum, as
of the date of this Agreement), any untrue statement of a material fact or
omitted to state a material fact necessary in order to make the statements
contained herein or therein not misleading in light of the circumstances when
made.  The projections and pro forma financial information contained in the
                           --- -----
materials referenced above are based upon good faith estimates and assumptions
believed by management of the Borrower to be reasonable at the time made, it
being recognized by the Lenders that such financial information as it relates to
future events is not to be viewed as fact and that actual results during the
period or periods covered by such financial information may differ from the
projected results set forth therein by a material amount.  There is no fact
known to any Loan Party that could reasonably be expected to have a Material
Adverse Effect that has not been expressly disclosed herein, in the other Loan
Documents, in the Confidential Information Memorandum or in any other documents,
certificates and statements furnished to the Agents and the Lenders for use in
connection with the transactions contemplated hereby and by the other Loan
Documents.

          4.19  Solvency.  Each Loan Party is, and after giving effect to the
                --------
incurrence of all Indebtedness and obligations being incurred in connection
herewith will be and will continue to be, Solvent.

          4.20  Year 2000 Matters.  Except where the failure to do so could not
                -----------------
reasonably be expected to have a Material Adverse Effect, any reprogramming
required to permit the proper functioning, in and following the year 2000, of
(i) the Borrower's computer systems and (ii) the Borrower's equipment containing
embedded microchips and the testing of all such systems and equipment owned by
the Borrower, as so reprogrammed, will be completed by September 30, 1999.  To
the knowledge of the Borrower, the cost to the Borrower of such reprogramming
and testing and of the reasonably foreseeable consequences of year 2000 to the
Borrower (including, without limitation, reprogramming errors and the failure of
others' systems or equipment) will not result in a Default or a Material Adverse
Effect.  Except for such of the reprogramming referred to in the preceding
sentence as may be necessary, the computer and management information systems of
the Borrower and its Subsidiaries are and, with ordinary course upgrading and
maintenance, will continue for the term of this Agreement to be, sufficient to
permit the Borrower to conduct its business without Material Adverse Effect.

          4.21   FCC and State Regulatory Compliance.  (a)  The Borrower and its
                 -----------------------------------
Subsidiaries are in compliance with (i) the Communications Act, (ii) all
applicable communications laws and regulations of any state of the United States
(the "States") and (iii), to the knowledge of the Borrower, all applicable
communications laws and regulations of any foreign jurisdiction (the "Foreign
Jurisdictions"), except in the case of the foregoing clauses (i), (ii) and (iii)
taken together to the extent that the failure to be in compliance could not
reasonably be expected to have a Material Adverse Effect.  To the knowledge of
the Borrower, there is no license or permit required for the operations of the
business of the Borrower or its Subsidiaries by any State or Foreign
Jurisdiction or by the FCC which is not held by the Borrower and its
Subsidiaries.

          (b)  The Borrower and its Subsidiaries hold the FCC Authorizations
identified in Schedule 4.21(b).  Except as described in Schedule 4.21(b), each
of such FCC Authorizations is in full force and effect and has not been revoked,
suspended, canceled, or modified in any adverse way and, except as may be set
forth on Schedule 4.21(b), is not subject to any conditions or requirements that
are not generally imposed by the FCC upon the holders of such authorizations.
The FCC Authorizations listed in Schedule 4.21(b) are the only FCC
Authorizations required for the conduct of the business of the Borrower and its
Subsidiaries as conducted on the Closing Date.  Neither the Borrower nor any of
its Subsidiaries holds any radio license issued by the FCC under Title III of
the Communications Act.

          (c)  Except as described on Schedule 4.21(c), (i) the Borrower has no
knowledge of any investigation, notice of apparent liability, violation,
forfeiture or other order or complaint issued by or before the FCC or any
governmental body in any State or any Foreign Jurisdiction, or of any other
proceedings of or before the FCC or any governmental body in any State or any
Foreign Jurisdiction, which could reasonably be expected to have a Material
Adverse Effect; and (ii) no proceedings are pending or, to the knowledge of the
Borrower, threatened, to revoke or limit any FCC Authorization, any permits,
certificates, licenses, registrations, tariff filings or approvals or other
authorizations from the States to conduct their current business (collectively
"State Permits") or any permits, certificates, licenses, registrations, tariff
 -------------
filings or approvals or other authorizations from the Foreign Jurisdictions to
conduct their current business (collectively "Foreign Permits"), except, in each
                                              ---------------
case, those the absence or violation of which do not and could not reasonably be
expected to have a Material Adverse Effect.

          (d)  Except as described on Schedule 4.21(d), the Borrower has no
knowledge of the occurrence of any event which results in, or after notice or
lapse of time or both would result in, (i) revocation, suspension, adverse
modification, non-renewal, impairment, restriction or termination of, or order
of forfeiture with respect to, any State Permit, Foreign Permit or FCC
Authorization or (ii) any requirement to obtain any FCC Authorization, State
Permit or Foreign Permit which (in the case of (i) and (ii) above), in any
respect, could reasonably be expected in the future to affect any of the rights
of the Borrower or any of its Subsidiaries under any State Permit, Foreign
Permit or FCC Authorization or the qualifications of the Borrower to conduct its
business consistent with the FCC's regulation and the applicable law of any
State or Foreign Jurisdiction in any respect that could reasonably be expected
to have a Material Adverse Effect, except such changes in laws or regulations in
any jurisdiction arising after the date of this
<PAGE>

                                                                              51

Agreement which are generally applicable in the industry and may affect the
Borrower or its Subsidiaries.

          (e)  Each of the Borrower and  its Subsidiaries has duly filed in a
timely manner all material filings, reports, applications, documents,
instruments and information required to be filed by it under the Communications
Act and all applicable State and Foreign Jurisdiction communications laws and
regulations, and all such filings were when made true, correct and complete in
all material respects, except to the extent that the failure to comply or the

          4.22  Security Documents.  The Guarantee and Collateral Agreement is
                ------------------
effective to create in favor of the Administrative Agent, for the benefit of the
Lenders, a legal, valid and enforceable security interest in the Collateral
described therein and proceeds thereof.  In the case of the Pledged Stock
described in the Guarantee and Collateral Agreement, when any stock certificates
representing such Pledged Stock are delivered to the Administrative Agent, and
in the case of the other Collateral described in the Guarantee and Collateral
Agreement, when financing statements in appropriate form are filed in the
offices specified on Schedule 4.22-1 (which financing statements have been duly
completed and executed and delivered to the Administrative Agent) and such other
filings and actions as are specified on Schedule 3 to the Guarantee and
Collateral Agreement  have been duly completed, the Guarantee and Collateral
Agreement shall constitute a fully perfected Lien on, and security interest in,
all right, title and interest of the Loan Parties in such Collateral and the
proceeds thereof, as security for the Obligations (as defined in the Guarantee
and Collateral Agreement), in each case prior and superior in right to any other
Person (except, in the case of Collateral other than Pledged Stock, Liens
permitted by Section 7.3 and, in the case of Pledged Stock, Liens that arise by
operation of law).  Schedule 4.22-2 lists each UCC Financing Statement that (i)
names any Loan Party as debtor and (ii) will remain on file after the Closing
Date.  Schedule 4.22-3 lists each UCC Financing Statement that (i) names any
Loan Party as debtor and (ii) will be terminated on or prior to the Closing
Date; and on or prior to the Closing Date, the Borrower will have delivered to
the Administrative Agent, or caused to be filed, duly completed UCC termination
statements, signed by the relevant secured party, in respect of each UCC
Financing Statement listed in Schedule 4.22-3.

     created thereby; or

          (j)  The guarantee contained in Section 2 of the Guarantee and
     Collateral Agreement shall cease, for any reason (other than by reason of
     the express release thereof pursuant to Section 10.15), to be in full force
     and effect or any Loan Party or any Affiliate of any Loan Party shall so
     assert in writing; or

          (k)  The failure of any of the Original Investors, or any other

     purchase of stock or assets, or any other similar transaction) an Original
     Investor or any or all of the common stock of the Borrower held by an
     Original Investor (so long as such telecommunications company is of a
     stature similar to, and other long term senior unsecured debt ratings of
     which by Standard & Poors Ratings Services and Moody's Investors Service,
     Inc., are equal to or higher than, that of the acquired Original Investor
     and so long as at least four of the Original Investors have not been so

     of directors of the Borrower or to otherwise control, directly or
     indirectly, through one or more intermediaries, the Borrower.

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) above with respect to the Borrower,
automatically the Commitments shall immediately terminate and the Loans
hereunder (with accrued interest thereon) and all other amounts owing under this
Agreement and the other Loan Documents (including, without limitation, all
amounts of L/C Obligations, whether or not the beneficiaries of the then
outstanding Letters of Credit shall have presented the documents required
thereunder) shall immediately become due and payable, and (B) if such event is
any other Event of Default, either or both of the following actions may be
taken: (i) with the consent of the Majority Revolving Credit Facility Lenders,
the Administrative Agent may, or upon the request of the Majority Revolving
Credit Facility Lenders, the Administrative Agent shall, by notice to the
Borrower declare the Revolving Credit Commitments to be terminated forthwith,
whereupon the Revolving Credit Commitments shall immediately terminate; and (ii)
with the consent of the Required Lenders, the Administrative Agent may, or upon
the request of the Required Lenders, the Administrative Agent shall, by notice
to the Borrower, declare the Loans hereunder (with
<PAGE>

                                                                              70

accrued interest thereon) and all other amounts owing under this Agreement and
the other Loan Documents (including, without limitation, all amounts of L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required thereunder) to be due and
payable forthwith, whereupon the same shall immediately become due and payable.
In the case of all Letters of Credit with respect to which presentment for honor
shall not have occurred at the time of an acceleration pursuant to this
paragraph, the Borrower shall at such time deposit in a cash collateral account
opened by the Administrative Agent an amount equal to the aggregate then undrawn
and unexpired amount of such Letters of Credit. Amounts held in such cash
collateral account shall be applied by the Administrative Agent to the payment
of drafts drawn under such Letters of Credit, and the unused portion thereof
after all such Letters of Credit shall have expired or been fully drawn upon, if
any, shall be applied to repay other Obligations of the Borrower hereunder and
under the other Loan Documents. After all such Letters of Credit shall have
expired or been fully drawn upon, all Reimbursement Obligations shall have been
satisfied and all other Obligations of the Borrower hereunder and under the
other Loan Documents (other than contingent indemnification and reimbursement
obligations) shall have been paid in full, the balance, if any, in such cash
collateral account shall be returned to the Borrower (or such other Person as
may be lawfully entitled thereto).

                             SECTION 9. THE AGENTS

          9.1  Appointment. Each Lender hereby irrevocably designates and
               -----------
appoints the Agents as the agents of such Lender under this Agreement and the
other Loan Documents, and each Lender irrevocably authorizes each Agent, in such
capacity, to take such action on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers and perform
such duties as are expressly delegated to such Agent by the terms of this
Agreement and the other Loan Documents, together with such other powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
elsewhere in this Agreement, no Agent shall have any duties or responsibilities,
except those expressly set forth herein, or any fiduciary relationship with any
Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against any Agent.

          9.2  Delegation of Duties. Each Agent may execute any of its duties
               --------------------
under this Agreement and the other Loan Documents by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. No Agent shall be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by it with
reasonable care.

          9.3  Exculpatory Provisions. Neither any Agent nor any of its
               ----------------------
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be
(i) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Agreement or any other Loan Document
(except to the extent that any of the foregoing are found by a final and
nonappealable decision of a court of competent jurisdiction to have resulted
from its or such Person's own gross negligence or willful misconduct) or (ii)
responsible in any manner to any of
<PAGE>

                                                                              71

the Lenders for any recitals, statements, representations or warranties made by
any Loan Party or any officer thereof contained in this Agreement or any other
Loan Document or in any certificate, report, statement or other document
referred to or provided for in, or received by the Agents under or in connection
with, this Agreement or any other Loan Document or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document or for any failure of any Loan Party a party thereto to
perform its obligations hereunder or thereunder. The Agents shall not be under
any obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document, or to inspect the properties, books or
records of any Loan Party.

          9.4  Reliance by Agents. Each Agent shall be entitled to rely, and
               ------------------
shall be fully protected in relying, upon any instrument, writing, resolution,
notice, consent, certificate, affidavit, letter, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to the Loan Parties), independent accountants and other
experts selected by such Agent. The Agents may deem and treat the payee of any
Note as the owner thereof for all purposes unless such Note shall have been
transferred in accordance with Section 10.6 and all actions required by such
Section in connection with such transfer shall have been taken. Each Agent shall
be fully justified in failing or refusing to take any action under this
Agreement or any other Loan Document unless it shall first receive such advice
or concurrence of the Required Lenders (or, if so specified by this Agreement,
all Lenders or any other instructing group of Lenders specified by this
Agreement) as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense that may
be incurred by it by reason of taking or continuing to take any such action.
Each Agent shall in all cases be fully protected in acting, or in refraining
from acting, under this Agreement and the other Loan Documents in accordance
with a request of the Required Lenders (or, if so specified by this Agreement,
all Lenders or any other instructing group of Lenders specified by this
Agreement), and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Lenders and all future holders of the
Loans.

          9.5  Notice of Default. No Agent shall be deemed to have knowledge or
               -----------------
notice of the occurrence of any Default or Event of Default hereunder unless
such Agent shall have received notice from a Lender or the Borrower referring to
this Agreement, describing such Default or Event of Default and stating that
such notice is a "notice of default". In the event that the Administrative Agent
shall receive such a notice, the Administrative Agent shall give notice thereof
to the Lenders and the Borrower. The Administrative Agent shall take such action
with respect to such Default or Event of Default as shall be reasonably directed
by the Required Lenders (or, if so specified by this Agreement, all Lenders or
any other instructing group of Lenders specified by this Agreement); provided
                                                                     --------
that unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable in the best interests of the
Lenders.

                                                                              72


          9.6  Non-Reliance on Agents and Other Lenders. Each Lender expressly
               ----------------------------------------
acknowledges that neither any of the Agents nor any of their respective
officers, directors, employees, agents, attorneys-in-fact or affiliates have
made any representations or warranties to it and that no act by any Agent
hereafter taken, including any review of the affairs of a Loan Party or any
affiliate of a Loan Party, shall be deemed to constitute any representation or
warranty by any Agent to any Lender. Each Lender represents to the Agents that
it has, independently and without reliance upon any Agent or any other Lender,
and based on such documents and information as it has deemed appropriate, made
its own appraisal of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Loan Parties and their
affiliates and made its own decision to make its Loans hereunder and enter into
this Agreement. Each Lender also represents that it will, independently and
without reliance upon any Agent or any other Lender, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit analysis, appraisals and decisions in taking or not taking action
under this Agreement and the other Loan Documents, and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Loan Parties and their affiliates. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, no Agent shall have any duty or responsibility
to provide any Lender with any credit or other information concerning the
business, operations, property, condition (financial or otherwise), prospects or
creditworthiness of any Loan Party or any affiliate of a Loan Party that may
come into the possession of such Agent or any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates.

          9.7  Indemnification. The Lenders agree to indemnify the
               ---------------
Administrative Agent in its capacity as such (to the extent not reimbursed by
the Borrower and without limiting the obligation of the Borrower to do so),
ratably according to their respective Aggregate Exposure Percentages in effect
on the date on which indemnification is sought under this Section (or, if
indemnification is sought after the date upon which the Commitments shall have
terminated and the Loans shall have been paid in full, ratably in accordance
with such Aggregate Exposure Percentages immediately prior to such date), for,
and to save the Administrative Agent harmless from and against, any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind whatsoever that may at any time
(including, without limitation, at any time following the payment of the Loans)
be imposed on, incurred by or asserted against the Administrative Agent in any
way relating to or arising out of, the Commitments, this Agreement, any of the
other Loan Documents or any documents contemplated by or referred to herein or
therein or the transactions contemplated hereby or thereby or any action taken
or omitted by the Administrative Agent under or in connection with any of the
foregoing; provided that no Lender shall be liable for the payment of any
           --------
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements that are found by a final and
nonappealable decision of a court of competent jurisdiction to have resulted
from such Agent's gross negligence or willful misconduct. The agreements in this
Section shall survive the payment of the Loans and all other amounts payable
hereunder.
<PAGE>

                                                                              73

          9.8  Agent in Its Individual Capacity. Each Agent and its affiliates
               --------------------------------
may make loans to, accept deposits from and generally engage in any kind of
business with any Loan Party as though such Agent were not an Agent. With
respect to its Loans made or renewed by it and with respect to any Letter of
Credit issued or participated in by it, each Agent shall have the same rights
and powers under this Agreement and the other Loan Documents as any Lender and
may exercise the same as though it were not an Agent, and the terms "Lender" and
"Lenders" shall include each Agent in its individual capacity.

          9.9  Successor Agents. The Administrative Agent may resign as
               ----------------
Administrative Agent upon 30 days' notice to the Lenders and the Borrower. If
the Administrative Agent shall resign as Administrative Agent under this
Agreement and the other Loan Documents, then the Required Lenders shall appoint
from among the Lenders a successor agent for the Lenders, which successor agent
shall (unless an Event of Default under Section 8(a) or Section 8(f) with
respect to the Borrower shall have occurred and be continuing) be subject to
approval by the Borrower (which approval shall not be unreasonably withheld or
delayed), whereupon such successor agent shall succeed to the rights, powers and
duties of the Administrative Agent, and the term "Administrative Agent" shall
mean such successor agent effective upon such appointment and approval, and the
former Administrative Agent's rights, powers and duties as Administrative Agent
shall be terminated, without any other or further act or deed on the part of
such former Administrative Agent or any of the parties to this Agreement or any
holders of the Loans. If no successor agent has accepted appointment as
Administrative Agent by the date that is 30 days following a retiring
Administrative Agent's notice of resignation, the retiring Administrative
Agent's resignation shall nevertheless thereupon become effective, and the
Lenders shall assume and perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Required Lenders appoint a successor
agent as provided for above. After any retiring Agent's resignation as Agent,
the provisions of this Section 9 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this Agreement and
the other Loan Documents.

          9.10 Authorization to Release Liens and Guarantees. The Administrative
               ---------------------------------------------
Agent is hereby irrevocably authorized by each of the Lenders to effect any
release of Liens or guarantee obligations contemplated by Section 10.15.

          9.11 The Arranger; the Documentation Agent. The Arranger, in its
               -------------------------------------
capacity as such, shall have no duties or responsibilities, and shall incur no
liability, under this Agreement and the other Loan Documents. The Documentation
Agent, in its capacity as such, shall have no duties or responsibilities, and
shall incur no liability, under this Agreement and the other Loan Documents.

                           SECTION 10. MISCELLANEOUS

          10.1 Amendments and Waivers. Neither this Agreement or any other Loan
               ----------------------

conditions as may be specified in the instrument of waiver, any of the
requirements of this Agreement or the other Loan Documents or any Default or
Event of Default and its consequences; provided, however, that no such waiver
                                       --------  -------
and no such amendment, supplement or modification shall:

     (i) forgive the principal amount or extend the final scheduled date of
     maturity of any Loan or Reimbursement Obligation, extend the scheduled date
     or change the amount of any amortization payment in respect of any Term
     Loan, reduce the stated rate of any interest or fee payable hereunder or
     extend the scheduled date of any payment thereof, or increase the amount or
     extend the expiration date of any Revolving Credit Commitment or Delayed
     Draw Term Loans Commitment of any Lender, in each case without the consent
     of each Lender directly affected thereby;

     Agreement and the other Loan Documents, release all or substantially all of
     the Collateral or release all or substantially all of the Subsidiary
     Guarantors from their guarantee obligations under the Guarantee and
     Collateral Agreement, in each case without the consent of all Lenders;

     (iii) amend, modify or waive any condition precedent to any extension of
     credit under the Delayed Draw Term Loan Facility or Revolving Credit
     Facility set forth in Section 5.2 (including, without limitation, the
     waiver of an existing Default or Event of Default required to be waived
     solely in order for such extension of credit to be made) without the
     consent of any Majority Facility Lenders with respect to the Delayed Draw
     Term Loan Facility or any Majority Revolving Credit Facility Lenders, as
     the case may be;

     (iv) reduce the percentage specified in the definition of Majority Facility
     Lenders with respect to any Facility without the written consent of all
     Lenders under such Facility;

     (v) amend, modify or waive any provision of Section 9 without the consent
     of any Agent directly affected thereby;

     (vi) amend, modify or waive any provision of Section 2.10 or 2.16 without
     the consent of each Lender directly affected thereby; or

     (vii) amend, modify or waive any provision of Section 3 without the consent
     of each Issuing Lender affected thereby.

Any such waiver and any such amendment, supplement or modification shall apply
equally to each of the Lenders and shall be binding upon the Loan Parties, the
Lenders, the Administrative Agent and all future holders of the Loans. In the
case of any waiver, the Loan Parties, the Lenders and the Administrative Agent
shall be restored to their former position and rights hereunder and under the
other Loan Documents, and any Default or Event of Default waived shall be deemed
to be cured and not continuing; but no such waiver shall extend to any
subsequent or other Default or Event of Default, or impair any right consequent
thereon. Any such waiver, amendment, supplement or modification shall be
effected by a written instrument signed by the parties required to sign pursuant
to the foregoing provisions of this Section; provided, that delivery of an
                                             --------
executed signature page of any such instrument by facsimile transmission shall

                ------------------------------
delay in exercising, on the part of any Agent or any Lender, any right, remedy,
power or privilege hereunder or under the other Loan Documents shall operate as
a waiver thereof; nor shall any single or partial exercise of any right, remedy,
power or privilege hereunder preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege. The rights,
remedies, powers and privileges herein provided are cumulative and not exclusive
of any rights, remedies, powers and privileges provided by law.

          10.4  Survival of Representations and Warranties.  All representations
                ------------------------------------------

shall survive the execution and delivery of this Agreement and the making of the
Loans and other extensions of credit hereunder.

          10.5  Payment of Expenses.  The Borrower agrees (a) to pay or
                -------------------
reimburse the Agents for all their reasonable out-of-pocket costs and expenses

payable to syndicate members), development, preparation and execution of, and

Documents and any other documents prepared in connection herewith or therewith,

and thereby, including, without limitation, the reasonable fees and

incurred in connection with the enforcement or preservation (including pursuant
to a "workout") of any rights under this Agreement, the other Loan Documents and
any such other documents, including, without limitation, the fees and

respective affiliates, and their respective officers, directors, trustees,
employees, advisors, agents and controlling persons (each, an "Indemnitee") for,

Indemnitee harmless from and against any and all other liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever with respect to the execution,
delivery, enforcement, performance and administration of this Agreement, the
other Loan Documents and any such other documents, including, without
limitation, any of the foregoing relating to the use of proceeds of the Loans or
the violation of, noncompliance with or liability under, any Environmental Law
applicable to the operations of the Borrower or any of its Subsidiaries or any
of the Properties and the fees and disbursements and other charges of legal
counsel in connection with claims, actions or proceedings by any Indemnitee
against the Borrower hereunder (all the foregoing in this clause
(d), collectively, the "Indemnified Liabilities"), provided, that the Borrower
                        -----------------------    --------
shall have no obligation hereunder to any Indemnitee with respect to Indemnified
Liabilities to the extent such Indemnified Liabilities resulted from the gross
negligence or willful misconduct of such Indemnitee. Without limiting the
foregoing, and to the extent permitted by applicable law, the Borrower agrees
not to assert and to cause its Subsidiaries not to assert, and hereby waives and
agrees to cause its Subsidiaries so to waive, all rights for contribution or any
other rights of recovery with respect to all claims, demands, penalties, fines,
liabilities, settlements, damages, costs and expenses of whatever kind or
nature, under or related to Environmental Laws, that any of them might have by
statute or otherwise against any Indemnitee, except with respect to any of the
foregoing arising out of the gross negligence or willful misconduct of such
Indemnitee. All amounts due under this Section shall be payable not later than
30 days after written demand therefor. Statements payable by the Borrower
pursuant to this Section shall be submitted to the Borrower in accordance with
Section 10.2, or to such other Person or address as may be hereafter designated
by the Borrower in a written notice to the Administrative Agent. The agreements
in this Section shall survive repayment of the Loans and all other amounts
payable hereunder.

          10.6  Successors and Assigns; Participations and Assignments.  (a)
                ------------------------------------------------------
This Agreement shall be binding upon and inure to the benefit of the Borrower,
the Lenders, the Agents, all future holders of the Loans and their respective
successors and assigns, except that the Borrower may not assign or transfer any
of its rights or obligations under this Agreement without the prior written
consent of the Agents and each Lender.

          (b)  Any Lender may, without the consent of the Borrower, in
accordance with applicable law, at any time sell to one or more banks, financial
institutions or other entities (each, a "Participant") participating interests
                                         -----------
in any Loan owing to such Lender, any Commitment of such Lender or any other
interest of such Lender hereunder and under the other Loan Documents. In the
event of any such sale by a Lender of a participating interest to a Participant,
such Lender's obligations under this Agreement to the other parties to this
Agreement shall remain unchanged, such Lender shall remain solely responsible
for the performance thereof, such Lender shall remain the holder of any such
Loan for all purposes under this Agreement and the other Loan Documents, and the
Borrower and the Agents shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement and the other Loan Documents. In no event shall any Participant under
any such participation have any right to approve any amendment or waiver of any
provision of any Loan Document, or any consent to any departure by any Loan
Party therefrom, except to the extent that such amendment, waiver or consent
would require the consent of all Lenders pursuant to Section 10.1. The

                                                                              78

Borrower agrees that if amounts outstanding under this Agreement and the Loans
are due or unpaid, or shall have been declared or shall have become due and
payable upon the occurrence of an Event of Default, each Participant shall, to
the maximum extent permitted by applicable law, be deemed to have the right of
setoff in respect of its participating interest in amounts owing under this
Agreement to the same extent as if the amount of its participating interest were
owing directly to it as a Lender under this Agreement, provided that, in
                                                       --------
purchasing such participating interest, such Participant shall be deemed to have
agreed to share with the Lenders the proceeds thereof as provided in Section
10.7(a) as fully as if such Participant were a Lender hereunder. The Borrower
also agrees that each Participant shall be entitled to the benefits of Sections
2.17, 2.18 and 2.19 with respect to its participation in the Commitments and the
Loans outstanding from time to time as if such Participant were a Lender;
provided that, in the case of Section 2.18, such Participant shall have complied
- --------
with the requirements of said Section, and provided, further, that no
                                           --------  -------
Participant shall be entitled to receive any greater amount pursuant to any such
Section than the transferor Lender would have been entitled to receive in
respect of the amount of the participation transferred by such transferor Lender
to such Participant had no such transfer occurred.

          (c)  Any Lender (an "Assignor") may, in accordance with applicable law
                               --------
and upon written notice to the Administrative Agent, at any time and from time
to time assign to any Lender, any affiliate thereof or a Related Fund of any
Lender or, with the consent of the Borrower and the Administrative Agent and, in
the case of any Assignment of the Revolving Credit Commitments, the written
consent of each then Issuing Lender (which, in each case, shall not be
unreasonably withheld or delayed), to an additional bank, financial institution
or other entity (an "Assignee") all or any part of its rights and obligations
                     --------
under this Agreement pursuant to an Assignment and Acceptance, substantially in
the form of Exhibit E, executed by such Assignee and such Assignor (and, where
the consent of the Borrower, the Administrative Agent or the then Issuing
Lenders is required pursuant to the foregoing provisions, by the Borrower and
such other Persons) and delivered to the Administrative Agent for its acceptance
and recording in the Register; provided that no such assignment to an Assignee
                               --------
(other than any Lender or any affiliate or a Related Fund thereof) shall be in
an aggregate principal amount of less than $5,000,000 (other than in the case of
an assignment of all of a Lender's interests under this Agreement), unless
otherwise agreed by the Borrower, and the Administrative Agent. Any such
assignment need not be ratable as among the Facilities. Upon such execution,
delivery, acceptance and recording, from and after the effective date determined
pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be
a party hereto and, to the extent provided in such Assignment and Acceptance,
have the rights and obligations of a Lender hereunder with Commitments and/or
Loans as set forth therein, and (y) the Assignor thereunder shall, to the extent
provided in such Assignment and Acceptance, be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all of an Assignor's rights and obligations under this Agreement, such Assignor
shall cease to be a party hereto, except as to Section 2.17, 2.18 and 10.5 in
respect of the period prior to such effective date). Notwithstanding any
provision of this Section, the consent of the Borrower shall not be required for
any assignment that occurs at any time when any Event of Default shall have
occurred and be continuing.

                                                                              79

          (d)  The Administrative Agent shall, on behalf of the Borrower,
maintain at its address referred to in Section 10.2 a copy of each Assignment
and Acceptance delivered to it and a register (the "Register") for the
                                                    --------
recordation of the names and addresses of the Lenders and the Commitments of,
and principal amount of the Loans owing to, each Lender from time to time. The
entries in the Register shall be conclusive, in the absence of manifest error,
and the Borrower, each Agent and the Lenders shall treat each Person whose name
is recorded in the Register as the owner of the Loans and any Note evidencing
such Loans recorded therein for all purposes of this Agreement. Any assignment
of any Loan, whether or not evidenced by a Note, shall be effective only upon
appropriate entries with respect thereto being made in the Register (and each
Note shall expressly so provide). Any assignment or transfer of all or part of a
Loan evidenced by a Note shall be registered on the Register only upon surrender
for registration of assignment or transfer of the Note evidencing such Loan,
accompanied by a duly executed Assignment and Acceptance; thereupon one or more
new Notes in the same aggregate principal amount shall be issued to the
designated Assignee, and the old Notes shall be returned by the Administrative
Agent to the Borrower marked "canceled". The Register shall be available for
inspection by the Borrower or any Lender (with respect to any entry relating to
such Lender's Loans) at any reasonable time and from time to time upon
reasonable prior notice.

          (e)  Upon its receipt of an Assignment and Acceptance executed by an
Assignor and an Assignee (and, in any case where the consent of any other Person
is required by Section 10.6(c), by each such other Person) together with payment
to the Administrative Agent of a registration and processing fee of $3,500
(except that no such registration and processing fee shall be payable in the
case of (i) an Assignee which is already a Lender or is an affiliate of a
Lender, a Related Fund of a Lender or a Person under common management with a
Lender and (ii) an Assignee of the Arranger), the Administrative Agent shall (i)
promptly accept such Assignment and Acceptance and (ii) on the effective date
determined pursuant thereto record the information contained therein in the
Register and give notice of such acceptance and recordation to the Lenders, the
Agents and the Borrower. On or prior to such effective date, the Borrower, at
its own expense, upon request, shall execute and deliver to the Administrative
Agent (in exchange for the Note of the assigning Lender) a new Note to such
Assignee or its registered assigns in an amount equal to the Revolving Credit
Commitment and/or, prior to the Delayed Draw Termination Date, the Available
Delayed Draw Term Loan Commitment, and/or applicable Term Loans, as the case may
be, assumed or acquired by it pursuant to such Assignment and Acceptance and, if
the Assignor has retained a Revolving Credit Commitment and/or, prior to the
Delayed Draw Termination Date, any Available Delayed Draw Term Loan Commitment,
and/or applicable Term Loans, as the case may be, upon request, a new Note to
the order of the Assignor in an amount equal to the Revolving Credit Commitment
and/or prior to the Delayed Draw Termination Date, the Available Delayed Draw
Term Loan Commitment, and/or applicable Term Loans, as the case may be, retained
by it hereunder. Such new Note or Notes shall be dated the effective date of the
applicable Assignment and Acceptance and shall otherwise be in the form of the
Note or Notes replaced thereby.

          (f)  For avoidance of doubt, the parties to this Agreement acknowledge
that the provisions of this Section concerning assignments of Loans and Notes
relate only to absolute assignments and that such provisions do not prohibit
assignments creating security interests,
<PAGE>

                                                                              80

including, without limitation, any pledge or assignment by a Lender of any Loan
or Note to any Federal Reserve Bank in accordance with applicable law. Any
Lender that is a fund that invests in bank loans may pledge all or any portion
of its rights in connection with this Agreement to the trustee for holders of
obligations owed, or securities issued, by such fund as security for such
obligations or securities, provided, that any foreclosure or other exercise of
remedies by such trustee shall be subject to the provisions of this Section 10.6
regarding assignment in all respects. No pledge described in the immediately
preceding clause shall release such Lender from its obligations hereunder.

          10.7  Adjustments; Set-off.  (a) Except to the extent that this
                --------------------
Agreement provides for payments to be allocated to a particular Lender or to the
Lenders under a particular Facility, if any Lender (a "Benefitted Lender") shall
                                                       -----------------
at any time receive any payment of all or part of the Obligations owing to it,
or receive any collateral in respect thereof (whether voluntarily or
involuntarily, by set-off, pursuant to events or proceedings of the nature
referred to in Section 8(f), or otherwise), in a greater proportion than any
such payment to or collateral received by any other Lender, if any, in respect
of such other Lender's Obligations, such Benefitted Lender shall purchase for
cash from the other Lenders a participating interest in such portion of each
such other Lender's Obligations, or shall provide such other Lenders with the
benefits of any such collateral, as shall be necessary to cause such Benefitted
Lender to share the excess payment or benefits of such collateral ratably with
each of the Lenders; provided, however, that if all or any portion of such
                     --------  -------
excess payment or benefits is thereafter recovered from such Benefitted Lender,
such purchase shall be rescinded, and the purchase price and benefits returned,
to the extent of such recovery, but without interest.

          (b)  In addition to any rights and remedies of the Lenders provided by
law, each Lender shall have the right, without prior notice to the Borrower, any
such notice being expressly waived by the Borrower to the extent permitted by
applicable law, upon any amount becoming due and payable by the Borrower
hereunder (whether at the stated maturity, by acceleration or otherwise), to set
off and appropriate and apply against such amount any and all deposits (general
or special, time or demand, provisional or final), in any currency, and any
other credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time
held or owing by such Lender or any branch or agency thereof to or for the
credit or the account of the Borrower.  Each Lender agrees promptly to notify
the Borrower and the Administrative Agent after any such setoff and application
made by such Lender, provided that the failure to give such notice shall not
                     --------
affect the validity of such setoff and application.

          10.8  Counterparts.  This Agreement may be executed by one or more of
                ------------
the parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument. Delivery of an executed signature page of this Agreement by
facsimile transmission shall be effective as delivery of a manually executed
counterpart hereof. A set of the copies of this Agreement signed by all the
parties shall be lodged with the Borrower and the Administrative Agent.

          10.9   Severability.  Any provision of this Agreement that is
                 ------------
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

          10.10  Integration.  This Agreement and the other Loan Documents
                 -----------
represent the entire agreement of the Borrower, the Agents, the Arranger and the
Lenders with respect to the subject matter hereof and thereof, and there are no
promises, undertakings, representations or warranties by the Arranger, any Agent
or any Lender relative to subject matter hereof not expressly set forth or
referred to herein or in the other Loan Documents.

          10.11  GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
                 -------------
OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

          10.12  Submission To Jurisdiction; Waivers.  The Borrower hereby
                 -----------------------------------
irrevocably and unconditionally:

          (a)  submits for itself and its Property in any legal action or
     proceeding relating to this Agreement and the other Loan Documents to which
     it is a party, or for recognition and enforcement of any judgment in
     respect thereof, to the non-exclusive general jurisdiction of the courts of
     the State of New York, the courts of the United States of America for the
     Southern District of New York, and appellate courts from any thereof;

          (b)  consents that any such action or proceeding may be brought in
     such courts and waives any objection that it may now or hereafter have to
     the venue of any such action or proceeding in any such court or that such
     action or proceeding was brought in an inconvenient court and agrees not to
     plead or claim the same;

          (c)  agrees that service of process in any such action or proceeding
     may be effected by mailing a copy thereof by registered or certified mail
     (or any substantially similar form of mail), postage prepaid, to the
     Borrower at its address set forth in Section 10.2 or at such other address
     of which the Administrative Agent shall have been notified pursuant
     thereto;

          (d)  agrees that nothing herein shall affect the right to effect
     service of process in any other manner permitted by law or shall limit the

          10.15  Release of Collateral and Guarantee Obligations.
                 -----------------------------------------------

          (a)  Notwithstanding anything to the contrary contained herein or in
     any other Loan Document, upon request of the Borrower in connection with
     any Disposition of Property permitted by the Loan Documents, the
     Administrative Agent shall (without notice to, or vote or consent of, any
     Lender, or any affiliate of any Lender that is a party to any Specified
     Hedge Agreement) take such actions as shall be required to release its
     security interest in any Collateral being Disposed of in such Disposition,
     and to release any guarantee obligations under any Loan Document of any
     Person being Disposed of in
<PAGE>

                                                                              83

     such Disposition, to the extent necessary to permit consummation of such
     Disposition in accordance with the Loan Documents.

          (b)  Notwithstanding anything to the contrary contained herein or any
     other Loan Document, when all principal and interest and all other
     Obligations then due and payable (other than Obligations in respect of any
     Specified Hedge Agreement and contingent indemnification and reimbursement
     obligations) have been paid in full, all Commitments have terminated or
     expired and no Letter of Credit shall be outstanding, upon request of the
     Borrower, the Administrative Agent shall (without notice to, or vote or
     consent of, any Lender, or any affiliate of any Lender that is a party to
     any Specified Hedge Agreement) take such actions as shall be required to
     release its security interest in all Collateral, and to release all
     guarantee obligations under any Loan Document, whether or not on the date
     of such release there may be outstanding Obligations in respect of
     Specified Hedge Agreements. Any such release of guarantee obligations shall
     be deemed subject to the provision that such guarantee obligations shall be
     reinstated if after such release any portion of any payment in respect of
     the Obligations guaranteed thereby shall be rescinded or must otherwise be
     restored or returned upon the insolvency, bankruptcy, dissolution,
     liquidation or reorganization of the Borrower or any Subsidiary Guarantor,
     or upon or as a result of the appointment of a receiver, intervenor or
     conservator of, or trustee or similar officer for, the Borrower or any
     Subsidiary Guarantor or any substantial part of its property, or otherwise,
     all as though such payment had not been made.

          10.16  Accounting Changes.  In the event that any "Accounting Change"
                 ------------------
(as defined below) shall occur and such change results in a change in the method
of calculation of financial covenants, standards or terms in this Agreement,
then the Borrower and the Administrative Agent shall enter into negotiations in
order to amend such provisions of this Agreement so as to equitably reflect such
Accounting Change with the desired result that the criteria for evaluating the
Borrower's financial condition shall be the same after such Accounting Change as
if such Accounting Change had not been made. Until such time as such an
amendment shall have been executed and delivered by the Borrower, the
Administrative Agent and the Required Lenders, all financial covenants,
standards and terms in this Agreement shall continue to be calculated or
construed as if such Accounting Change had not occurred. "Accounting Change"
refers to changes in accounting principles required by the promulgation of any
rule, regulation, pronouncement or opinion by the Financial Accounting Standards
Board of the American Institute of Certified Public Accountants or, if
applicable, the SEC.

          10.17  WAIVERS OF JURY TRIAL.  THE BORROWER, THE AGENTS AND THE
                 ---------------------
LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL
ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND
FOR ANY COUNTERCLAIM THEREIN.

          10.18  Limitation of Interest.  It is the intent of the Borrower and
                 ----------------------
the Lenders in the execution and performance of this Agreement and all matters
incidental and related hereto and the other Loan Documents or any agreement or
instrument executed in connection herewith
<PAGE>

                                                                              84

or therewith or with any Indebtedness of the Borrower to the Lenders to remain
in strict compliance with all laws applicable to the Lenders from time to time
in effect, including, without Limitation, usury laws. In furtherance hereof, the
Borrower and the Lenders stipulate and agree that none of the terms and
provisions contained in or pertaining to this Agreement or in the other Loan
Documents or any other agreement or instrument ("Other Agreement") executed in
                                                 ---------------
connection herewith or with any Indebtedness of the Borrower to the Lenders
shall ever be construed to create a contract to pay for the use, forbearance or
detention of money with interest at a rate or in an amount in excess of the
maximum amount of interest permitted to be charged by the Lenders under all laws
in effect and applicable to the Lenders (the "Maximum Rate"). For purposes of
                                              ------------
this Agreement and the Notes, "interest" shall include the aggregate of all
amounts which constitute or are deemed to constitute interest under the
respective laws in effect and applicable to the Lenders that are contracted for,
chargeable, receivable (whether received or deemed to have been received) or
taken under this Agreement or the Notes or any Other Agreement. The Borrower
shall not be required to pay interest hereunder or on any Note or any Other
Agreement at a rate or in an amount in excess of the Maximum Rate with respect
to the Lenders or the maximum amount of interest that may be lawfully charged by
the Lenders under any law which is in effect and applicable to the Lenders, and
the provisions of this Section 10.18 shall control over all other provisions of
this Agreement and the Notes or any Other Agreement which may be in apparent
conflict herewith. If the effective rate or amount of interest which would
otherwise be payable under this Agreement or any Note or any Other Agreement, or
all of them, would exceed the Maximum Rate for the Lenders or the maximum amount
of interest the Lenders or any holder of any Note or any Other Agreement is
allowed by the relevant applicable law to charge, contract for, take or receive
or in the event the Lenders or any holder of any Note or any Other Agreement
shall charge, contract for, take or receive monies that are deemed to constitute
interest which could, in the absence of this provision, increase the effective
rate or amount of interest payable under this Agreement or any Note or any Other
Agreement, or all of them, to a rate or amount in excess of that permitted to be
charged, contracted for, taken or received under the applicable laws then in
effect with respect to the Lenders, then the principal amount of the Notes or
the obligations of the Borrower to the Lenders under this Agreement, the Notes
or any Other Agreement or the amount of interest which would otherwise be
payable to or for the account of the Lenders under this Agreement or the Notes
or any Other Agreement or all of them, shall be reduced to the amount allowed
under said laws as now or hereafter construed by the courts having jurisdiction,
and all such monies so charged, contracted for, or received that are deemed to
constitute interest in excess of the Maximum Rate for the Lenders or maximum
amount of interest permitted by the relevant applicable laws shall be
immediately returned to or credited to the account of the Company upon such
determination. In determining whether the interest paid or payable under any
specific contingency exceed the Maximum Rate, the Borrower and the Lenders
shall, to the maximum extent permitted by applicable law, (i) characterize any
non-principal payment as an expense, fee (excluding attorneys' and accountants'
fees) or premium rather than interest and (ii) amortize, prorate, allocate and
spread, in equal parts during the full term of the relevant Note, all interest
at any time contracted for, charged or received in connection with the relevant
Note.

     ISC agrees to and does hereby grant to Representative the right to market
     and resell the use of Infonet Services as defined herein, within the
     Territory.


3.   TRADEMARKS OR SERVICE MARKS
     ---------------------------

     3.1  ISC hereby grants to Representative, during the term and subsequent
          renewals of this Agreement, the non-transferable right and
          authorization to use within the Territory the Trademarks or Service
          Marks.

     3.2  Representative shall use the Trademarks or Service Marks only in
          respect to providing Infonet Services, the rights to which have been
          granted herein, and any services related thereto, so long as this
          Agreement remains in effect.

     3.3  Representative acknowledges the title of ISC to the Trademarks or
          Service Marks in the Territory and elsewhere and the validity of the
          registration of ISC as the proprietor in the Register of Trademarks or
          Service Marks. Representative shall not claim any ownership or similar
          right to the Trademarks or Service Marks by reason of their use
          thereof pursuant to this Agreement, and any rights which
          Representative should otherwise acquire in or to the Trademarks or
          Service Marks shall be deemed for the account and benefit of ISC.

     3.4  Representative shall use its best endeavors to preserve the value and
          validity of the Trademarks or Service Marks and in particular will:

          3.4.1  Endeavor to create, promote, and retain goodwill in the
                 business of selling the goods and services.

          3.4.2  Give to ISC any information as to Representative's use of the
                 Trademarks or Service Marks which ISC may require and otherwise
                 render any assistance to ISC in maintaining the Trademarks or
                 Service Marks duly registered except that ISC shall pay all
                 renewal fees.

                                       3
<PAGE>

          3.4.3  Use the Trademarks or Service Marks correctly spelled as
                 registered and not as a verb or in the plural.

          3.4.4  Not to use the Trademarks or Service Marks unaccompanied by
                 words describing the nature of the goods and services to which
                 they relate unless the Trademarks or Service Marks in question
                 are capitalized or otherwise distinguished from the surrounding
                 and adjacent text.

          3.4.5  In the event that the Trademarks or Service Marks are to be
                 used with another trademark or service mark or in relation to
                 the goods and services under the control of Representative,
                 Representative will use its best efforts to have both
                 trademarks or service marks represented equally legibly,
                 equally prominently, and of the same size as each other but
                 nevertheless separated from the other so that each mark appears
                 to be a mark in its own right distinct from the other mark.

          3.4.6  Representative agrees not to use in its business any other
                 trademark which is similar to or so nearly resembles the
                 Trademarks or Service Marks or any of them as to be likely to
                 cause deception or confusion.

          Revenues generated from provision of Infonet Services to customers
          contracting with Representative in the Territory. Invoices will be
          issued on a monthly basis.

    6.3   Any technology transfer tax, sales or turnover tax, value added tax,
          currency export tax, registration tax, or any other taxes as may be
          applied to the amounts payable to ISC hereunder shall be borne by
          Representative and not deducted from such amounts; except that any
          taxes by the national government or any other government

                                       5
<PAGE>

          on ISC's income (or a third party's income) hereunder shall be borne
          by ISC, or a third party as the case may be and, if required by law,
          shall be deducted from any payments made to ISC. If it is required by
          law that Representative deduct taxes from ISC's income hereunder then
          Representative agrees promptly to provide ISC with the original copy
          of each paid tax receipt on any taxes so withheld from payments to
          ISC, or a third party.

     6.5  Representative agrees that services utilized hereunder will not be
          used in contravention of national or international communications
          regulations, laws, or tariffs. Representative further agrees that in
          providing Infonet Services it will neither undertake, nor cause nor
          permit to be undertaken, any activity which either (a) is illegal
          under any laws, decrees, rules, or regulations in effect in the
          Territory, or (b) would have the effect of causing ISC to be in
          violation of any laws, decrees, rules, or regulations in effect in the
          Territory.

     6.6  Representative agrees that ISC has the right to approve the prices to
          be established by Representative for Infonet Services, the rights to
          which are granted hereunder, prior to any such prices being published
          and made available to Representative's customers in the Territory.
          Such approval shall not be unreasonably withheld.

     6.7  Representative and ISC will agree upon revenue targets to be achieved
          in the Territory for each calendar year starting with the first
          complete calendar year after the date of this Agreement, consistent
          with reasonable growth of the revenue in the Territory. In the event
          that the parties are not able to reach an agreement by the end of a
          calendar year, the revenue target for the following calendar year
          shall be two (2) times the revenue for the second and third quarter of
          the current calendar year multiplied by the average growth rate
          experienced by other Infonet representatives in the same region (as
          used herein, regions as defined for Notice Private services).
          Representative will make diligent efforts to achieve the targets. If
          the agreed revenue targets are not met, or if the parties fail to
          reach an agreement on revenue targets for two consecutive calendar
          years, ISC may, at its discretion, terminate this Agreement by giving
          one hundred eighty (180) days notice in writing to Representative.

     6.8  Representative and ISC will agree upon the number of job positions,
          the functions of the established positions, the number of employees to
          be assigned to the established positions, and the Representative
          employees assigned to the established positions required for the
          marketing, sales, and support efforts needed in the provision of
          Infonet Services, including an appropriately staffed helpdesk pursuant
          to the Infonet Customer Support Guidelines. If the parties fail to
          reach

           at its discretion, terminate this Agreement by giving one hundred
           eighty (180) days notice in writing to Representative.

     6.9   Representative agrees to ensure that the employees assigned in
           accordance with paragraph 6.8 are properly trained and fully made
           aware of Infonet Services, and Infonet policies and procedures. As
           part of this commitment, Representative agrees to actively
           participate in ISC's regional and global conferences. Further,
           Representative and ISC will establish, when appropriate but at least
           once a year, specific training programs for each employee assigned to
           sell or support Infonet Services, and Representative will ensure that
           each employee will attend the specified ISC training courses or
           sessions.

           Services in accordance with ISC's standard support policies and

           inquiries received from ISC or Host Lessees, as hereinafter defined,
           within twenty-four (24) hours excluding weekends and holidays in
           ____________. Further, Representative will maintain, or make
           arrangements for the maintenance of the site for the Infonet node,
           and the test and monitoring equipment, in accordance with the
           specifications in the aforementioned standard support policies and
           procedures.

     6.11  Representative, to the extent permitted by law and regulations,
           agrees to provision Global Connect Services in accordance with the
           then current Global Connect policies and procedures. ISC reserves the
           right to audit Representative's compliance with the Global Connect
           policies and procedures.

     6.12  Representative shall forward the reports, as requested by ISC,
           necessary to monitor and manage the provisioning of Infonet Services
           in Representative's Territory.

     6.13  If Representative fails to meet its commitments as set forth in
           Paragraphs 6.9, 6.10, 6.11, and 6.12 above, ISC may, at its
           discretion, terminate this Agreement by giving one hundred eighty
           (180) days notice in writing to Representative.

     6.14  Representative agrees to subscribe to a white and/or yellow page
           listing in the appropriate telephone directories which would
           reference that the Representative is an Infonet Services provider,
           and would provide the telephone number to be used by an Infonet
           Services user to reach Representative.

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

     7.1   Should Representative acquire a customer with business interests in

<PAGE>

          and such customer operates on a multi-national basis and desires that
          its offices and/or personnel outside of the Territory shall have
          access to the common data base and/or program library and/or computer
          system totally or partially dedicated to the customer's use, then ISC
          and Representative agree that Representative shall have the primary
          responsibility to furnish the services specified in the Appendices to
          such customer (hereafter "Multi-National Customer") outside of the
          areas in which Representative is doing business.

     7.2  All expenses except as specifically set forth in Paragraph 7.3 arising
          from the acceptance of a Multi-National Customer shall be borne by
          Representative.

          National Customer's offices and/or personnel located in a country or
          place where ISC has not assigned, leased, or licensed others to
          perform Infonet services, ISC agrees to supply Normal Customer Support
          Services at ISC's expense when requested to do so by Representative
          provided that ISC is then currently providing such support services
          for its own customers in the immediate vicinity.

     7.4  Whenever Representative provides Infonet Services to a Multi-National
          Customer's offices and/or personnel located in a country or place
          where ISC has assigned, leased, or licensed others to perform Infonet
          Services, ISC agrees to exercise a diligent effort to bring about an
          agreement between Representative and ISC's assignee, lessee, or
          licensee (the "Host Lessee") which will require the Host Lessee to
          supply Normal Customer Support Services on the same terms as set forth
          in Paragraphs 7.3 above and 7.5 below.

     7.5  Whenever Representative provides Infonet Services to a Multi-National
          Customer, Representative agrees to pay to ISC (or Host Lessee as the
          case may be) the revenue share amounts set forth in the Appendices
          where ISC (or the Host Lessee) supplies Normal Customer Support
          Services.

     7.6  At the request and expense of Representative, ISC agrees to conduct an
          audit of any entity furnishing Infonet Services for which the
          Representative is entitled to receive revenues for the rendition of
          Normal Customer Support Services under this Agreement. ISC will submit
          to Representative a report of the findings of the audit. Expenses at
          any audit so conducted will be calculated based upon ISC's normal and
          prevailing labor rates and expenses incurred.

     7.7  Should ISC (or a Host Lessee provided that such Host Lessee has agreed
          to provide Normal Customer Support Services under Paragraph 7.4)
          acquire a customer with principal business interests outside of the
          Territory and such customer operates on a multi-national basis and
          desires that its offices and/or personnel within the Territory shall
          have access to a common data base and/or program library and/or
          computer system totally or partially dedicated to the customer's use
          located outside of the

                                       8

          Territory, Paragraph 7.1 through 7.5 shall apply mutatis mutandis.

     made available to Representative from network nodes configured to ISC
     specifications, installed at Representative's site, via an international
     leased line or lines from the aforementioned nodes to ISC network gateway
     nodes.  The costs for the international leased line(s) will be borne by the
     parties hereto in accordance with such cost-sharing agreements as may be
     agreed to from time-to-time by ISC and Representative.  Access to the
     aforementioned services will be made available in accordance with the then
     current provisions of Annex 1 of this Agreement.

     10.1  ISC warrants that the services, systems, and products furnished by
           ISC under this Agreement will be substantially similar to the
           services, systems, and products made available by ISC in the United
           States. THE PARTIES AGREE THAT ISC WILL NOT BE HELD TO ANY OTHER
           WARRANTIES DIRECTLY OR INDIRECTLY RELATED TO SERVICES, SYSTEMS, AND
           PRODUCTS, WHETHER EXPRESSED OR IMPLIED, INCLUDING BUT NOT LIMITED TO
           THE WARRANTY OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

     10.2  ISC shall not be liable for, and Representative assumes and will save
           harmless, ISC, its directors, officers, employees, and agents in
           respect of any loss, claim, damage, liability, or expense, including
           reasonable attorney's fees, that may arise through the marketing and
           use of the services, systems, and products in the Territory. In no
           event shall ISC be liable for any indirect, incidental, special,
           exemplary, or consequential damages such as, but not limited to, loss
           of anticipated profits or other economic loss, in connection with or
           arising out of the furnishing, performance, or use of the services,
           systems, and products provided for in this Agreement.

     10.3  Except as otherwise provided in this Agreement, neither party shall
           be held liable for any failure to perform or delay in performance of
           any obligation hereunder for reasons of "force majeure". The term
           "force majeure" as employed hereunder shall mean, but not be limited
           to, acts of God, acts or omissions of governments, acts or omissions
           of military authorities, strikes, lock-outs, or other industrial
           disturbances, acts of the public enemy, wars, blockades,
           insurrections, riots, epidemics, landslides, earthquakes, fires,
           storms, lightning, floods, washouts, civil disturbances, and any
           other acts or omissions, not within the control of the affected party
           and which by the exercise of due diligence said party is unable to
           overcome.


11.  TERM OF AGREEMENT AND TERMINATION
     ---------------------------------

     11.1  The duration of this Agreement shall be for a period of three (3)
           years from the date

                                       10
<PAGE>

           hereof, unless earlier terminated under the provisions of this
           Agreement. It is further agreed that this Agreement and the rights
           and authorizations granted hereunder shall be renewed automatically
           for additional successive one (1) year periods unless either party
           notifies the other party in writing of its intention not to have
           Agreement and the rights and authorizations renewed at least one
           hundred eighty (180) days prior to the expiration date of this
           Agreement, or its subsequent renewals.

     11.2  Either party may terminate this Agreement on ninety (90) days notice
           in writing to the other party upon failure of the other party to
           perform any of its obligations hereunder; provided, however, that
           during such ninety (90) day period the party in default shall have
           fulfilled its obligations, this Agreement shall continue in effect as
           if such notice had not been given.

     11.3  The right of termination by Representative or ISC under Paragraph
           11.2 and Paragraph 11.4 or by ISC under Paragraph 11.5 shall be in
           addition to any other rights or remedies permitted by operation of
           law or in equity or under any other provision of this Agreement.

     11.4  Subject to the rights of termination to ISC by Paragraph 11.5 below,
           either party may, upon written notice to the other, terminate and
           cancel this Agreement in the event that the other party voluntarily
           files a bankruptcy petition, and said petition is not disposed of
           within thirty (30) days, or in the event that the other party is
           insolvent and unable to pay its debts as they mature, or if such
           party shall make an assignment for the benefit of creditors or have a
           receiver appointed for it or its property.

     11.5  In the event Representative fails to make any payments required under
           this Agreement, ISC shall notify Representative of such failure in
           writing. ISC may terminate this Agreement and all rights and licenses
           hereunder upon thirty (30) days written notice if Representative
           fails to make the required payment within thirty (30) days following
           the receipt of the payment failure notice. The provisions of this
           paragraph shall not apply if Representative's failure to perform or
           delay in performance are for reasons of force majeure.

     11.6  In the event Representative establishes a business relationship with
           a service vendor other than ISC that provides substantially similar
           services to the services described herein, ISC reserves the right, at
           its discretion to terminate this Agreement by giving one hundred
           eighty (180) days notice in writing to Representative.

     11.7  ISC reserves the right to take all actions, including termination of
           services provided to Representative or Representative's customers
           pursuant to this Agreement, which ISC considers necessary to comply
           with applicable national or international communications regulations,
           laws, or tariffs.

12.  EFFECTS OF NONRENEWAL OR TERMINATION
     ------------------------------------

     12.1  In the event of expiration or termination of the Agreement, ISC will
           at its option assume responsibility for the Infonet Multi-National
           Customers in the Territory. Representative will exercise all
           diligence in transferring such customers to ISC's responsibility or
           the responsibility of ISC's nominee. Representative will pay the
           costs incurred by its own personnel in meeting the obligations of
           this paragraph.

     12.2  Expiration or termination of this Agreement shall not relieve the
           parties of any obligations due at the time of such expiration or
           termination, nor shall such expiration or termination prejudice any
           claim of either party accrued on account of any default or breach by
           the other.

     12.3  The non-renewal or termination of this Agreement shall not affect
           services in place for Representative's customers which explicitly or
           by their nature would continue beyond the non-renewal or termination
           of the Agreement unless the parties hereto both agree to have all
           such services concluded upon cessation of the Agreement.

     12.4  Upon agreement in writing by the parties hereto, ISC shall (i)
           support Representative's customers operating under this Agreement
           until the end of such customer's contract period; (ii) allow for the
           provision of additional circuits [sites], and new or additional
           Infonet Services, under an existing customer contract, and (iii)
           extend a customer's contract to a date beyond the termination of this
           Agreement if both ISC and Representative agree in writing.

     12.5  Upon termination or expiration of this Agreement, the Parties
           acknowledge that surviving obligations listed in Paragraph 12.4
           above, are subject to the following provisions: (i) prices for
           services shall be at ISC's then current prices; and (ii) the
           discounts offered under this Agreement are not valid after the
           completion of the customer's commitment period.


13.  POST TERMINATION
     ----------------

     Upon the non-renewal or termination of this Agreement, for any reasons
     whatsoever:

          products made available hereunder.

     (b)  Representative shall as soon as reasonably practical cause all entries
          in published material such as telephone directories to be removed and
          shall cause all stationery, advertisements, promotional materials, and
          signs to be changed, removed, or expunged so as to eliminate any
          reference to the Trademarks or Service Marks.

                                       12
<PAGE>

     (c)   Representative shall not thereafter use any trading style, trade
           name, trademark, or service mark which is similar to or so nearly
           resembles the Trademarks or Service Marks or any of them, as would or
           might be likely to cause confusion.

     (d)   Representative shall return to ISC within sixty (60) days of
           termination all copies of internal manuals, all copies of
           documentation, papers, and materials marked or stamped with the words
           designating such documents, or copies thereof, as proprietary or
           confidential to ISC, and all ISC copyrighted materials, and generally
           all documentation, papers, and materials referring to or concerning
           the provision of the services provided hereunder being in the
           possession of Representative at the time of termination.

     17.1  This Agreement shall be construed and governed by the substantive

           rules regarding choice of laws.

18.  ASSIGNMENT OF THE AGREEMENT
     ---------------------------

     18.1  Neither party shall assign, pledge, or in any manner delegate,
           transfer, convey, alienate, or encumber any right arising from or
           interest in the Agreement without obtaining the prior written consent
           of the other party, which consent shall not be unreasonably withheld.
           Any of the foregoing actions without such prior written consent shall
           be a nullity, and of no force nor effect.

     18.2  For Purposes of this Agreement, an "assignment", "pledge",
           "delegation," transfer", "conveyance", "alienation" or "encumbrance"
           shall be deemed to include, and be subject to the prior consent
           requirement of Paragraph 18.1, if: (a) Representative is acquired by,
           merged or consolidated into another entity; (b) all or substantially
           all the assets of Representative or a business unit of Representative
           responsible for the sale of INFONET services or products are acquired
           by another entity, or (c) Representative experiences a change of
           control, where "control" is defined as (i) change in ownership of at
           least 50% of the equity or beneficial ownership of

                                       15
<PAGE>

           Representative, or (ii) a change in the right to vote for or appoint
           a majority of the board of directors (or other governing body) of
           Representative, or (iii) the management or operational control of
           Representative by any entity (even though such entity may own less
           than 50% of the equity of Representative).


19.  SEVERABILITY
     ------------

     If one or more of the provisions or part thereof in this Agreement is held
     by a court of competent jurisdiction to be invalid, illegal, or
     unenforceable in any respect, the validity, legality, or enforceability of
     the remaining provisions shall not in any way be affected or impaired
     thereby. Notwithstanding the foregoing, ISC and Representative shall
     thereupon negotiate in good faith in order to agree to the term of a
     mutually satisfactory provision(s) to be substituted for the provision(s)
     so found to be void or unenforceable.


20.  INDEPENDENT CONTRACTOR
     ----------------------

     Relationship of parties hereunder shall always and only be that of
     independent contractors.


21.  NON-DISCLOSURE OF PROPRIETARY INFORMATION
     -----------------------------------------

     During the term of this Agreement it is anticipated that the parties hereto
     will disclose, each to the other, certain material and information which
     the disclosing party deems to be proprietary and confidential. The parties
     hereto agree to accept such information as proprietary and confidential
     that is appropriately identified in writing as such, and agree not to
     disclose hereafter such information and material to third parties. The
     parties hereto further agree to restrict circulation of such proprietary
     and confidential material and information within their own organization
     except to the extent necessary to fulfill the purposes of this Agreement.
     This restriction on the disclosure of proprietary information and materials
     will not apply to information which is in the public domain other than as a
     result of the acts or omissions of a party which was under an obligation to
     maintain the confidentiality of such materials and information.


22.  WAIVER
     ------

     No waiver of any remedy or of any default or breach of any covenant by
     either party hereunder shall be implied from any omission by either party
     to take action on account of such default if such default persists or is
     repeated, and no express waiver shall affect any default other than the
     default specified in the waiver, and then said waiver shall be operative
     only for the time and to the extent therein stated. Waivers of any
     covenant, term, or condition contained herein by either party shall not be
     construed as a waiver of any subsequent breach of the same covenant, term,
     or condition. A waiver of any right or

                                       16
<PAGE>

     remedy by a party hereto shall be construed as having been made only if
     express written notice of such waiver is delivered to the other party.

23.  INFRINGEMENT
     ------------

     23.1  Should Representative learn of any infringement or threatened
           infringement of the Trademarks or Service Marks, or any other
           registered mark licensed under this Agreement, or any unfair
           competition, or that any third party alleges or claims that such
           Trademarks or Service Marks are liable to cause deception or
           confusion to the public, Representative will forthwith notify ISC
           giving any particulars thereof and will provide all information and
           assistance to ISC in the event that ISC decides that proceedings
           should be commenced or defended. Any such proceedings shall be under
           the control of ISC and at ISC's cost.

     23.2  Should any third party allege infringement by use of the Registered
           Trademarks or Service Marks in the Territory by Representative, ISC
           will defend Representative against any such allegation. All such
           defenses shall be under ISC's control and at ISC's cost.
           Representative undertakes to assist ISC so far as it is within its
           power in the defense of such infringement proceedings.

     insofar as may be necessary to carry out this Agreement or conform to law.

     parties and is intended as the entire understanding between the parties and

          days' prior notice of the date it wishes to activate any of the
          Capacity.

     i.   Subject to payment of the purchase price for the Capacity Purchaser
          wishes to activate pursuant hereto, Purchaser shall have the right to
          use such Capacity from the date of activation until the end of its
          design life (25 years after 8 October 1997) or if earlier until the
          FLAG Cable System is decommissioned, which earlier decommissioning
          requires the unanimous agreement of FLAG and the FLAG Cable System
          landing parties under the C&MA. Purchaser shall not, pursuant to this
          Agreement, have any ownership or other rights in the FLAG Cable System
          itself. Nevertheless, except as otherwise provided in this Agreement,

[*] Confidential treatment requested

          Purchaser and FLAG, Purchaser shall have the rights and remedies under
          the C&MA with respect to the use of the Capacity as if Purchaser were
          a Non-Landing Party Signatory to the C&MA. FLAG shall have no greater
          obligations with regard to the Capacity or the use thereof than it
          would have under the C&MA if Purchaser were a Non-Landing Party
          Signatory to the C&MA.

2.   PAYMENTS

     a.   Purchaser shall pay to FLAG the purchase price of US$[*] for the
          Capacity (which includes standby operation and maintenance charges) as
          follows:

          (i)   [*]

          (ii)  [*]

          (iii) [*]

          FLAG shall render invoices for such amounts. For purposes hereof,
          activation of Capacity shall be as set forth in the FLAG Operations
          and Maintenance Plan.

     b.   Purchaser shall pay the required charges for each Drop and Insert
          prior to its activation. FLAG shall render invoices for such charges.

     c.   Purchaser shall pay to FLAG all other amounts and at such times as are
          set forth in, or determined pursuant to, Schedule 2 hereto.

     d.   Except for the payment under Section 2a(i), which is payable no later
          than 30 June 1999, Purchaser shall pay all invoices rendered by FLAG
          within 30 days after receipt by Purchaser. Any amount payable pursuant
          to this Agreement which is not paid when due shall accrue interest at
          the annual rate of 3% above the U.S. dollar LIBOR for one month as
          quoted in The Wall Street Journal on the first business day of the
                    -----------------------
          month in which the payment is due. All such default interest shall
          accrue from the day following the date payment of the relevant amount
          was due until it is paid in full. Such interest shall be payable on
          demand.

     e.   All amounts payable by Purchaser pursuant hereto shall be paid in full
          in U.S. dollars by wire transfer to such account as FLAG may by notice
          to Purchaser designate, without setoff or counterclaim and without
          reduction for any deduction or withholding for or on account of any
          tax, duty or other charge of whatever nature imposed by any taxing
          authority of the country of Purchaser. If Purchaser is required by law
          to make any deduction or withholding from any payment hereunder,
          Purchaser shall gross up the amount payable so that after such
          deduction or withholding the net amount received by FLAG will be not
          less than the amount FLAG would have received had such deduction or
          withholding not been required. Purchaser shall make the required
          deduction or withholding, shall pay the amount so deducted or withheld
          to the relevant governmental authority and shall promptly provide FLAG
          with evidence of such payment.

3.   PORTABILITY

     Purchaser may change the United Kingdom or Japan landing points of the
     Prime STM-1 or any Prime DS-3 or the landing points of any Drop and Insert
     at any time after it has been fully activated (provided that within the
     Prime STM-1 or each Prime DS-3 the STM-1s or DS-3s, as applicable, remain
     concatenated). Purchaser shall give FLAG not less than 90 days' notice of
     its desire to make any such change, which change will be subject to
     availability of the requested capacity on the FLAG Cable System and to
     Purchaser obtaining access to the FLAG Cable System through the relevant
     landing stations. The new capacity shall be Capacity for all purposes of
     this Agreement and the replaced capacity shall cease to be Capacity. Before
     the requested capacity is activated, Purchaser shall pay to FLAG a
     portability fee of US$[*].

4.   DEFAULT

     In the event that Purchaser shall have failed to pay any amount payable by
     Purchaser pursuant hereto for more than 30 days after its due date, then
     FLAG may upon 15 days' notice to Purchaser deactivate all then activated
     Capacity until Purchaser has paid in full all amounts overdue together with
     applicable default interest.

operate to exonerate or discharge the Guarantors from their obligations under

                                   ARTICLE I.
                                  DEFINITIONS

          Section 1.1  Certain Definitions.  In this Deed, the capitalized terms
                       -------------------
defined in Schedule 1.1 hereto shall have the meanings set forth or referred to
therein.

                                  ARTICLE II.
                                  CALL OPTION

to purchase with full title guarantee, at its sole option (the "Call Option")
                                                                -----------

                                       1
<PAGE>

          Section 2.2  Term of Call Option.  The time period (the "Option
                       -------------------                         ------
Period") during which ISC may exercise the Call Option shall commence on the day
- ------
following the Commencement Date and shall end at 5.00 pm London time on the
third anniversary of the Commencement Date; provided, however, that the Option
                                            --------  -------
Period shall end on the date of termination of the Management Agreement if
earlier; and provided, further, that if ISC has provided a Valuation Notice in
             --------  -------
accordance with Section 2.5 below with respect to a Valuation Date falling
within the Option Period, then ISC shall be entitled to exercise the Call Option
in accordance with Section 2.6(a) below with respect to the Written
Determination delivered pursuant to such Valuation Notice, whether or not the
date of such exercise occurs subsequent to the Option Period. If ISC has not
exercised the Call Option within the Option Period (or subsequent to the Option
Period to the extent set forth in the proviso above), the Call Option will
expire on the third anniversary of the Commencement Date without any further
action by the parties and be of no further force and effect. The Call Option may
be exercised no more than once in a calendar year by ISC during the Option
Period.

          Section 2.3  Call Price. The Call Price shall be exclusive of VAT if
                       ----------
payable and shall be equal to the Fair Market Value (as determined pursuant to
the provisions of Section 2.4 below) of the Assets on the Valuation Date (such
Call Price not to exceed Euro 123,246,000 (one hundred and twenty three million,
two hundred and forty six thousand Euro)).

          Section 2.4  Fair Market Value.  In order to determine from time to
                       -----------------
time the Fair Market Value of the Assets which are listed in a Valuation Notice
for purposes of permitting ISC to determine whether to exercise the Call Option,
upon receipt of a Valuation Notice, ISC and Unisource (on behalf of itself,
Unisource Nominee, the Unisource Stockholders or the AUCS Entities and
Subsidiaries (as applicable)) shall use their reasonable best efforts to
mutually agree on the Fair Market Value of the Assets, determined as provided in
Section 2.4(b), as of the Valuation Date. A Valuation Notice may only be served
up to two times in any calendar year. In the event they are unable to agree the
Fair Market Value of the Assets within ten business days of the date of the
Valuation Notice (the "Consultation Period"), then the Fair Market Value of the
                       -------------------
Assets shall be determined by appraisal pursuant to this Section 2.4, as
follows:

          (a)  The Fair Market Value of the Assets shall be determined for the
relevant Valuation Date by an appraiser mutually acceptable to ISC and
Unisource. If ISC and Unisource are unable to agree on an appraiser within ten
business days following expiration of the Consultation Period, the appraiser
shall be selected by the President for the time being of the Institute of
Chartered Accountants of England and Wales upon application by ISC or Unisource
whose choice of appraiser shall be binding upon the parties. The appraiser shall
conduct an appraisal under Section 2.4(b) and determine the Fair Market Value of
the Assets, which shall be final and binding on the parties to this Deed.
Unisource and ISC will equally share in the payment of the fees and expenses of
any appraiser named pursuant to this Section 2.4(a), unless otherwise determined
by the appraiser or the Arbitrators appointed under Section 9.2.

          (b)  The Fair Market Value of the Assets as of the Valuation Date
shall be determined on the day before the Valuation Date and after giving due
regard to the principles set forth in Schedule 2.4(b) and any other factors the
appraiser deems relevant, using accepted

                                       2
<PAGE>

valuation practices. In determining the Fair Market Value of the Assets, the
appraiser appointed under this Deed shall set forth its determination in writing
together with its opinions and the consideration upon which the opinions are
based (a "Written Determination"), with a signed counterpart to be delivered to
          ----------------------
each of ISC and Unisource within thirty days of commencing appraisal. Unisource
Sub, Unisource Nominee, the AUCS Entities and Subsidiaries shall provide access
to the appraiser to all of their records, except as restricted by law, and to
their employees, in order to enable the appraiser to make its determination.

          (c)  Any appraiser selected pursuant to Section 2.4(a) shall be an
investment bank of recognized international standing with respect to the
valuation of assets similar in nature to the Assets.

          Section 2.5  Valuation Notice.  At any time no less than thirty days
                       ----------------
and no more than sixty days prior to a Valuation Date ISC shall be entitled to
give notice (the "Valuation Notice") to Unisource requiring that the Fair Market
                  ----------------
Value of the Assets identified in the Valuation Notice be determined as of such
Valuation Date. The term "Valuation Date" shall mean a date within the Option
                          --------------
Period. For purposes of determining the Call Price, a determination of Fair
Market Value of the Assets, pursuant to Section 2.4 shall be binding if ISC
exercises the Call Option within thirty business days after receipt by ISC and
Unisource of the Written Determination required in Section 2.4 (or thirty
business days after ISC and Unisource mutually agree upon the Fair Market Value,
if applicable).

          Section 2.6  Exercise of Call Option.
                       -----------------------

          (a)  The Call Option may be exercised during the Option Period (or
subsequent to the Option Period to the extent set forth in the proviso of
section 2.2) at any time within thirty business days after receipt by ISC of the
Written Determination required in Section 2.4 (or thirty business days after ISC
and Unisource mutually agree upon the Fair Market Value, if applicable) by ISC
delivering a written notice of exercise ("Exercise Notice") to Unisource
                                          ---------------
specifying the date, which date shall be at least five days after the
date of the Exercise Notice but no later than 75 days after such date, upon
which ISC shall acquire the Assets (the "Option Commencement Date"); provided,
                                         ------------------------    --------
however, that the Option Commencement Date may be extended by ISC as reasonably
- -------
necessary in order to obtain any requisite governmental approvals, and if the
Option Commencement Date is so extended, the Option Commencement Date shall be
thirty (30) business days following receipt of such requisite governmental
approvals. Such exercise of the Call Option may be subject to the conditions set
forth in Section 2.6(b) below. If the Assets are not purchased because any of
the conditions in Section 2.6(b) are not met, the right to exercise the Call
Option at a future date in respect of the Assets will not be lost, assuming ISC
could otherwise give a Valuation Notice in such future period or periods.

          (b)  The completion of ISC's acquisition of the Assets pursuant to the
exercise of the Call Option shall take place at the London office of Latham &
Watkins (or such other place in London or in Amsterdam as is specified by ISC)
at 10:00 a.m. local time on the Option Commencement Date. ISC shall deliver to
Unisource (on behalf of AUCS N.V., AUCS v.o.f. and any Subsidiary which is
selling Assets in respect of which the Call Option is being

                                       3
<PAGE>

exercised) the Call Price payable in Immediately Available Funds and the AUCS
Entities shall deliver or cause delivery to ISC of physical possession of all
the Assets capable of passing by delivery with the intent that title in such
Assets shall pass by and upon such delivery and take such other actions as are
necessary to transfer ownership of the Assets to ISC. The Assets shall be
conveyed to ISC free and clear of all Encumbrances and with full title
guarantee.

     Unless waived by ISC, in its discretion, it shall be a condition to ISC's
obligation to purchase the Assets at such completion that customary
representations and warranties will be given by the Unisource Entities as of the
Option Commencement Date.  It shall be a condition to the obligation of the
Unisource Entities to consummate the sale of the Assets that all necessary
consents, approvals and authorizations of third parties and governmental
agencies required to be obtained with respect to the acquisition of the Assets
(including compliance with all necessary requirements under competition law)
shall have been obtained as of the Option Commencement Date; provided that each
of the Unisource Entities, the AUCS Entities and ISC shall take whatever steps
are reasonably necessary to obtain such consents, approvals and authorizations
to permit the legal transfer of the Assets to ISC and to ensure that ISC's
consummation of the purchase of the Assets will not create an event of default
under any of the Unisource Entities' or AUCS Entities' credit agreements or give
rise to an acceleration or requirement to make a change of control offer with
respect to any indebtedness of the Unisource Entities' or AUCS Entities;
provided that ISC shall not be obligated to dispose of any assets to obtain any
- --------
such consent, authorization or approval.  Each Party shall bear on its own
expenses incurred in connection with obtaining such consents, approvals and
authorizations.  Receipt by Unisource of the Call Price shall be full discharge
of all obligations of ISC to Unisource, the AUCS Entities or any Subsidiary to
pay for the Assets provided that ISC may direct that any or all of the Assets
acquired pursuant to this Deed shall be conveyed to any Affiliate.  Upon
purchase of the Assets ISC shall assume the related contractual obligations in
respect of such Assets incurred from and after the Option Commencement Date but
only to the extent disclosed by Unisource to ISC at the time of such transfer.

          Section 2.7  Exclusive Call Option.  This Call Option grants ISC the
                       ---------------------
sole right during the Option Period to acquire the Assets. ISC shall not
exercise the Option in respect of all or any material part of the Assets if such
exercise will leave the AUCS Entities unable to perform in all material respects
their obligations under any agreement between AUCS and any third party unless
reasonably satisfactory arrangements were put in place by the Parties to enable
AUCS Entities to fulfill such contractual objectives.

                                 ARTICLE III.
                                     TAXES

          Section 3.1  General.  The Party responsible under applicable law will
                       -------
pay documentary and transfer taxes, sales, use or other taxes for fees imposed
as a result of the execution or delivery of this Deed or the consummation of the
transactions contemplated hereby including all stamp duty, VAT and other taxes,
and notaries' fees.

                                       4
<PAGE>

          Section 3.2  VAT.  In the event that any tax authorities determine
                       ---
that VAT is chargeable in respect of the sale of Assets pursuant to this Call
Option Deed, Unisource shall deliver a valid VAT invoice therefor to ISC.

                                  ARTICLE IV.

          Section 7.2  If the AUCS Entities shall make default in the payment
when due of any amount payable to ISC and/or any other party under this Deed or
arising from the termination hereof, the Guarantors shall forthwith on demand by
ISC unconditionally pay to ISC in the manner prescribed in this Deed an amount
equal to the amount payable by the AUCS Entities.

          Section 7.3  As an independent and primary obligation, without
prejudice to Section 7.1 the Guarantors hereby unconditionally and irrevocably
agree to indemnify and keep indemnified ISC against all and any losses, costs,
claims, liabilities, damages, demands and expenses suffered or incurred by ISC
and/or any other Party arising from failure of the AUCS Entities to comply with
any of their obligations or discharge any of their liabilities under this Deed

time, performance or otherwise howsoever, or by any other indulgence being given
to the AUCS Entities or by any variation of the terms of this Deed or by any
act, thing, omission or means whatever which, but for this provision, might
operate to exonerate or discharge the Guarantors from their obligations under
the guarantee and indemnity continued in this Article.

                                  INDEMNITIES

          Section 8.1  Indemnity of the Unisource Entities and the AUCS
                       ------------------------------------------------
Entities.  The Unisource Entities and the AUCS Entities will, severally, defend,
- --------
indemnify and hold harmless ISC, its Affiliates and partners and their officers,
directors, employees and agents from all liabilities, damages, costs and
expenses (including, without limitation, reasonable counsel fees and expenses)
incurred in connection with (i) any breach by the Unisource Entities and/or the
AUCS Entities of their obligations under this Deed, or (ii) any third party
claim against ISC relating to breaches by the Unisource Entities of any of their
representations or warranties or any of their obligations hereunder provided
that the Unisource Entities and/or the AUCS Entities will not be liable pursuant
to this Section 8.1, (i) unless the aggregate amount otherwise due to ISC, its
Affiliates and partners and their officers, directors, employees and agents
exceeds on a cumulative basis Euro 100,000 and (ii) if such breach of any
representation or warranty or any of

                                       8
<PAGE>

their obligations under this Deed is caused by any willful misconduct or
negligence on the part of ISC.

          Section 8.2  Indemnification Procedures:  In the case of any claim
                       ---------------------------
asserted by a third party against a party entitled to indemnification under this
Deed (the "Indemnified Party"), notice shall be given by the Indemnified Party
           -----------------
to the party required to provide indemnification (the "Indemnifying Party")
                                                       ------------------
promptly after such Indemnified Party has actual knowledge of any claim as to
which indemnity may be sought, and the Indemnified Party shall permit the
Indemnifying Party (at the expense of such Indemnifying Party) to assume the
defence of any claim or any litigation resulting therefrom, provided that (i)
the counsel for the Indemnifying Party who shall conduct the defence of such
claim or litigation shall be reasonably satisfactory to the Indemnified Party,
(ii) the Indemnified Party may participate in such defence at such Indemnified
Party's expense, and (iii) the omission by any Indemnified Party to give notice
as provided herein shall not relieve the Indemnifying Party of its
indemnification obligation under this Deed except to the extent that such
omission results in a failure of actual notice to the Indemnifying Party and
such Indemnifying Party is materially damaged as a result of such failure to
give notice. Except with the prior written consent of the Indemnified Party, no
Indemnifying Party, in the defence of any such claim or litigation, shall
consent to entry of any judgment or enter into any settlement that provides for
injunctive or other non-monetary relief affecting the Indemnified Party or that
does not include as an unconditional term thereof the giving by each claimant or
plaintiff to such Indemnified Party of a release from all liability with respect
to such claim or litigation. In the event that the Indemnified Party shall in
good faith determine that the conduct of the defence of any claim subject to
indemnification hereunder or any proposed settlement of any such claim by the
Indemnifying Party might be expected to affect adversely the Indemnified Party's
tax liability or the ability of Indemnified Party to conduct its business, or
that the Indemnified Party may have available to it one or more defences or
counterclaims that are inconsistent with one or more of those that may be
available to the Indemnifying Party in respect of such claim or any litigation
relating thereto, the Indemnified Party shall have the right at all times to
take over and assume control over the defence, settlement, negotiations or
litigation relating to any such claim at the sole cost of the Indemnifying
Party, provided that if the Indemnified Party does so take over and assume
       --------
control, the Indemnified Party shall not settle such claim or litigation without
the written consent of the Indemnifying Party, such consent not to be
unreasonably withheld. In the event that the Indemnifying Party does not accept
the defence of any matter as above provided, the Indemnified Party shall have
the full right to defend against any such claim or demand and shall be entitled
to settle or agree to pay in full such claim or demand. In any event, the
Indemnifying Party and the Indemnified Party shall cooperate in the defence of
any claim or litigation subject to this Article VIII and the records of each
shall be available to the other with respect to such defence.

                                  ARTICLE IX.
                                 MISCELLANEOUS

transfer of all or substantially all the

                                       9

transfer, such transferee shall agree in writing with the other Parties to fully
perform and discharge all of the obligations of the relevant seller or
transferor under this Deed, except with the prior written approval of the other
Parties, which approval shall not be unreasonably withheld or delayed.

          Section 9.2  Governing Law and Arbitration.
                       -----------------------------

          (a)  This Deed shall be governed by and shall be construed in
accordance with English law, without reference to the choice of law provisions
thereof. Accordingly any dispute arising out of or having any connection with
this Deed shall be decided exclusively in accordance with English law, provided
that all such disputes shall be referred, in the first instance, to the
respective chief executive officers of the Parties for resolution.

          (b)  If a dispute, after having first been discussed by the chief
executive officers of each of the relevant Parties (provided that if the dispute
                                                    --------
is between ISC and an AUCS Entity, the matter shall be discussed between the
chief executive officers of ISC and Unisource), is not resolved by the said
chief executive officers within a maximum of 14 days, the dispute shall be
referred to and finally resolved by arbitration under the London Court of
International Arbitration ("LCIA") Arbitration Rules, which Arbitration Rules
                            ----
are deemed to be incorporated by reference to this Section 9.2.

          (c)  Any arbitration commenced pursuant to Section 9.2 shall be
administered by the LCIA and the standard LCIA administrative procedures and
schedule of costs shall apply. In any such arbitration, the appointing authority
shall be the LCIA. The number of arbitrators shall be three and such arbitrators
to include persons experienced in European telecommunications (the
"Arbitrators"). The place of arbitration shall be London and the language used
 -----------
in the arbitral proceedings shall be English. The governing law of the Agreement
shall be the substantive law of England.

          (d)  The fees of the Arbitrators, the costs of the LCIA and the cost
of the other parties relating to the arbitration (including, but not limited to,
the reasonable costs of professional advisers) shall be borne by those Parties
against whom the Arbitrators make any award in the proportion of any such award.

          (e)  The Arbitrators shall have authority to award interest on any
amount awarded by the Arbitrators up to the date of that award at the rate equal
to 1 (one) percentage point above the three month EURIBOR rate for Euros from
time to time. If any amount payable as a result of a decision of the Arbitrators
is not paid within 14 days of publication of that decision, interest will
thereafter accrue on the amount at the rate equal to 2 (two) percentage points
above the three month EURIBOR rate for Euros from time to time.

          (f)  The referral of a dispute to arbitration under Section 9.2 shall
not preclude any Party from obtaining interim relief on an urgent basis from a
court of competent jurisdiction pending any decision of the Arbitrators.

                                       10
<PAGE>

          (g)  Any decision of the Arbitrators shall be final, conclusive and
binding on the parties, and the parties agree to exclude, so far as lawfully
possible to exclude, any right of application or appeal to the English (or
other) courts in connection with any question of law arising in the arbitration
or in connection with any award or decision made by the Arbitrators, except as
may be necessary to enforce such award or decision.

          (h)  The provisions of this Section are severable from the rest of
this Deed and shall remain in effect despite the termination of or invalidity
for any reason of this Deed.

          Section 9.3  No Partnership.  Nothing in this Deed shall be deemed to
                       --------------
create any joint venture, partnership or principal and agent relationship
between any Unisource Entity, any AUCS Entity or Subsidiary and ISC and no party
shall hold itself out in its advertising or otherwise in any manner which would
indicate or imply any such relationship with the other.

          Section 9.4  Validity.  If any provision of this Deed is found or held
                       --------
to be invalid or unenforceable, the validity of all the other provisions hereof
shall not be affected thereby and the parties agree to meet and review the
matter and if any valid and enforceable means is reasonably available to achieve
the same object as the invalid or unenforceable provision, to adopt such means
by way of variation of this Deed.

          Section 9.5  Severability.  In the event that any of the terms of this
                       ------------
Deed are found to be invalid, unlawful or unenforceable, such terms (provided
that they are not fundamental to the deed) shall be severable from the remaining
terms, which shall continue to be valid and enforceable.

          Section 9.6  Variation.  No variation of or addition to this Deed
                       ---------
shall be of any force or effect unless reduced to writing, signed by or on
behalf of the Parties and expressed to amend this Deed.

          Section 9.7  Entire Agreement.  This Deed (including the documents
                       ----------------
referred to in it) replaces all prior agreements and arrangements between the
Parties and constitutes the entire understanding between the Parties relating to
the subject matter of this Deed. Each Party acknowledges that in agreeing to
enter into this Deed it has not relied on any representations, warranties or
promises (except those set out in this Deed) made by or on behalf of the other
Parties before the signature of this Deed. Each Party waives all rights and
remedies which, but for this Section, might otherwise be available to it in
respect of any such representation, warranty or promise, provided that nothing
in this Section shall limit or exclude any liability for fraud.

          Section 9.8  Waiver.  A waiver by a Party of a breach of any term or
                       ------
condition of this Deed in any one instance shall be in writing and shall not be
deemed as a continuing waiver or a waiver of any other or subsequent breach
unless the written notice so provides.

          Section 9.9  Notices.
                       -------

          (a)  The Parties choose the following addresses as the address at

                                 ARTICLE III.
                            SERVICES TO BE PROVIDED

          Section 3.1    Management Services.
                         --------------------

(a)  Except as otherwise expressly provided in this Agreement (including in this
Section 3.1 and Article XII), throughout the Term, ISC shall have the exclusive
right to manage the business, affairs, operations and actions of the AUCS
Entities as determined by ISC in its sole discretion. ISC is hereby empowered to
take any and all actions regarding the operations, strategy, marketing,
services, products, administration and general business of the AUCS Entities, as
determined by it in its sole and exclusive discretion.

                                       2
<PAGE>

(b)  The Parties agree that:

              (i)  the Supervisory Board of AUCS N.V. shall continue in
existence and have only the powers set forth in Section 12.1 of this Agreement;
and

              (ii) all other rights of the Unisource Entities under any
governing document or law with respect to the AUCS Entities shall be exercised
as directed by ISC.

(c)  In exercising its management powers under Section 3.1(a), ISC will use its
best efforts to act as a responsible manager of the AUCS Entities. In its
management of the AUCS Entities and while seeking over time to reduce the
expenses of the AUCS Entities, ISC will (i) use commercially reasonable efforts
to ensure continuity of Contract Services to customers, (ii) cause the AUCS
Entities to comply with the terms of the AT&T Exit Agreements and the
WorldPartners Membership Agreements, and (iii) cause the AUCS Entities to comply
in all material respects with the laws of all relevant jurisdictions.

(d)  The AUCS Entities, the Unisource Entities and the Indirect AUCS
Stockholders shall procure that the management boards of the AUCS Entities shall
appoint additional, changed or new officers (including the management director
and managing directors) as ISC shall recommend from time to time during the
Term, as soon as practicable upon ISC's recommendation, provided that such
appointments shall be subject, only to the extent required by applicable law, to
the advice of any works councils of AUCS. The Unisource Entities and the
Indirect AUCS Stockholders shall procure that the management boards of the AUCS
Entities shall not appoint additional, changed, or new officers (including the
management director and managing directors) or remove any of the foregoing
without the prior consultation and approval of ISC.

(e)  In order to effectuate the foregoing provisions of this Article III and to
fully empower ISC, each of the AUCS Entities hereby irrevocably appoints ISC and
any of its executive officers, their true and lawful attorney with full power of
substitution and with power for such person or entity in its own name and
capacity, together or separately, or in the name and capacity of the respective
AUCS Entity to manage the business, affairs, operations and actions of the
respective AUCS Entity as determined by ISC in its sole discretion; provided,
                                                                    --------
however, that such agency shall not create any fiduciary obligations. The
- -------
foregoing power of attorney is coupled with an interest.

(f)  Promptly following the Commencement Date, ISC shall (at AUCS' expense)
commence a review of the business, assets, operations, and prospects of the AUCS
Entities and prepare a proposal for the future operations of the AUCS Entities
(the "Review of Operations"). The Review of Operations shall consider, among
      --------------------
other things the profitability or potential profitability of the Contract
Services or other services, and the marketing, products, services,
administration, employee-related matters and general business of the AUCS
Entities. Every month during the preparation of the Review of Operations and
promptly following finalization of the Review of Operations ISC shall (i)
consult with the Indirect AUCS Stockholders as to the contents of the Review of
Operations (or the then current draft thereof) and (ii) inform Unisource to such
an extent which enables it to continue properly informing and consulting with
the Unisource European Works Council. ISC shall complete the Review of
Operations as soon as

                                       3
<PAGE>

practicable and in any event within 90 days following the Commencement Date.
Attached hereto as Exhibit 3.1(f) is a non-binding, preliminary draft
implementation plan and a non-binding outline social plan prepared by ISC and
presented by AUCS to the works council of AUCS.

                                  ARTICLE IV.
                             FUNDING REQUIREMENTS

          Section 4.1    Funding Requirements.
                         ---------------------
(a)  The Parties recognize that the AUCS Entities are likely to incur continuing
losses and in order to continue their business, it will be necessary for
Unisource to contribute further funds during the Term (the "Funding
                                                            -------
Requirements") to the AUCS Entities.  During the Term all Funding Requirements
- ------------
of the AUCS Entities will be paid by Unisource, by way of capital contribution
or loans (as described in Section 5.4), as and when requested by ISC pursuant to
Section 4.1(e) up to the limits set forth in Section 4.1(b). Funding
Requirements arising as a result of each of the categories (i) through (iv) set
forth in the following sentence shall be separately accounted for by AUCS when
made and each category shall be mutually exclusive. The Funding Requirements may
arise as a result of (i) the AUCS Entities' EBITDA Losses; (ii) Restructuring
Costs; (iii) Management Fees (payable pursuant to Section 5.1); and (iv)
Liquidation Costs (if any).

(b)  If the aggregate total of the AUCS Entities' Adjusted EBITDA Losses during
the Initial Term reaches Euro 368,316,000 (three hundred and sixty eight million
three hundred and sixteen thousand Euro) the "Review Point" shall have been
                                              ------------
reached.

(c)  If during the Initial Term, Management Accounts are delivered to Unisource
by AUCS showing that the Review Point has been exceeded, Unisource may
determine, within 30 days of receipt of such Management Accounts to terminate
this Agreement in accordance with Section 7.1(d) and (i) to liquidate the AUCS
Entities or (ii) take any other course of action not in violation of this
Agreement during the period of effectiveness of this Agreement and, if any such
determination to terminate this Agreement is made, Unisource shall so notify ISC
in writing, received by ISC within such 30 day period. Forthwith following such
determination, Unisource shall liquidate the AUCS Entities entirely at its own
cost and expense and in any event the Unisource Entities and the Indirect AUCS
Stockholders shall severally ensure that any and all of the obligations of the
AUCS Entities to Infonet are satisfied, whether by a Unisource Entity or an
Indirect AUCS Stockholder in place of the AUCS Entities or by some other
arrangement acceptable to ISC. In the event of a liquidation on a solvent basis,
Section 12.5 shall apply. If during the Initial Term, Management Accounts are
delivered to ISC by AUCS showing that the Review Point has been exceeded, ISC
may determine within 30 days of delivery of such Management Accounts to ISC to
terminate this Agreement in accordance with Section 7.1(d). If any such
determination is made, ISC shall so notify Unisource in writing, received by
Unisource within such 30 day period. For the avoidance of doubt, both Unisource
and ISC shall always have the right during the Initial Term to make any
determination permitted under this Section 4.1(c) within 30 days of receipt of
any Management Accounts which show that the Review Point has been exceeded.

                                       4
<PAGE>

(d)  Unisource shall make any Funding Requirement payments only to AUCS pursuant
to this Section 4.1 as requested by AUCS as directed by ISC and no later than 30
days after Unisource receives a written request therefor from ISC. Funding
Requirements shall be contributed as set forth in Section 5.4.

(e)  In order to assist Unisource in meeting such Funding Requirements, ISC
shall cause AUCS to provide Unisource with non-binding cash flow forecasts
setting forth AUCS' best estimates of the anticipated Funding Requirements for
the next calendar month, three months and year, such cash flow forecasts to be
provided not less than 30 days prior to commencement of the relevant period. The
untimely delivery of any such forecasts shall not limit in any way Unisource's
obligations under this Section 4.1 provided that no written request delivered
                                   --------
pursuant to Section 4.1(d) shall be binding on Unisource until the cash flow
forecast for the relevant period has been provided to Unisource. Any cash
surplus or deficit as set forth in the Commencement Date Financial Statements
(defined below) shall be considered an advance payment or an additional amount
due (as the respective case may be) in respect of any Funding Requirement.

(f)  ISC shall cause AUCS to prepare and to deliver to ISC and Unisource within
60 days following the Commencement Date, Consolidated Financial Statements,
prepared in accordance with Schedule C (the "Commencement Date Financial
                                             ---------------------------
Statements").  In connection with the Commencement Date Financial Statements,
- -----------
the Parties agree that in respect of revenues and costs of the AUCS Entities
represented by full and final settlements with customers and service providers
(rather than normal invoicing procedures) prior to the Commencement Date, such
settlements shall reflect fairly the relative proportion of the volume of the
business with such service provider or customers in the period prior to the
Commencement Date and that the settlement process shall be prepared and executed
with active involvement of Unisource. If within 30 days following the delivery
of the Commencement Date Financial Statements neither ISC nor Unisource has
given notice of its objection to the Commencement Date Financial Statements
(such notice must contain a statement of the basis of the objection) to the
other, then the Commencement Date Financial Statements shall be deemed to be
agreed between the Parties. If either ISC or Unisource gives such notice of
objection, Unisource and ISC will negotiate to resolve the issues in dispute for
14 days (or such longer period as they shall mutually agree) and, if not so
resolved, then the issues in dispute will be submitted to such independent "Big
5" accountants as ISC and Unisource agree and, in default of agreement such
independent "Big 5" firm of accountants as approved by the President for the
time being of the Institute of Chartered Accountants of England and Wales upon
the application of ISC or Unisource (the "Accountants"), for resolution and
                                          -----------
the Accountants shall be instructed to prepare independently audited
Commencement Date Financial Statements. If issues in dispute are submitted to
the Accountants for resolution, (i) each Party to this Agreement will furnish to
the Accountants such workpapers and other documents and information relating to
the AUCS Entities and the disputed issues as the Accountants may request and are
available to that Party or its subsidiaries (or its independent public
accountants), and Unisource and ISC will be afforded the opportunity to present
to the Accountants any material relating to the determination and to discuss the
determination with the Accountants; (ii) the determination by the Accountants,
as set forth in a notice delivered to Unisource and ISC by the Accountants and
the audited Commencement Date Financial Statements prepared by the Accountants,
will be binding and conclusive on the Parties;

                                       5
<PAGE>

and (iii) AUCS will bear the fees of the Accountants for such determination and
the preparation of the audited Commencement Date Financial Statements.

(g)  The Commencement Date Financial Statements shall be used to determine the
AUCS Entities' Adjusted EBITDA Losses during the Initial Term.

          Section 4.2  Capital Expenditures
                       --------------------

(a)  During the Term, it is anticipated that certain capital expenditures
("Capital Expenditure") shall be required to be made by the AUCS Entities
 ---------------------
for, amongst other things, maintenance and upgrade of the data transmission
platforms of the AUCS Entities.

(b)  Unisource agrees, in addition to the Funding Requirements, to provide such
funding to AUCS , as and when requested by AUCS as directed by Infonet, as will
permit Capital Expenditure by the AUCS Entities of up to Euro 2,844,000 (two
million eight hundred and forty four thousand Euro) over the Initial Term plus
                                                                          ----
any additional Capital Expenditure as is approved by the Supervisory Board, no
later than 30 days after Unisource has received a written request therefor, and
in the case of additional Capital Expenditure no later than 30 days after any
additional Capital Expenditure has been approved by the Supervisory Board.

(c)  Unisource shall have no obligation to fund any Capital Expenditure on
Infonet native platforms.

                                  ARTICLE V.
                             INVOICES AND PAYMENTS

          Section 5.1  Management Fee.  For each calendar quarter of the
                       ---------------
Initial Term, AUCS will pay to ISC in arrears, a fee in Euro equal to 1.5 per
cent of the total consolidated revenues of the AUCS Entities for such quarter as
set forth in the Management Accounts as a management fee (the "Management Fee")
                                                               --------------
up to an aggregate maximum during the Initial Term of Euro 17,065,000 (seventeen
million and sixty five thousand Euro) (plus any applicable VAT and any non
recoverable Dutch withholding taxes or any replacement therefor). AUCS shall pay
the Management Fee to ISC no later than the 30th calendar day of the month
following the last day of the calendar quarter for which the Management Fee is
due. AUCS shall pay the Management Fee by wire transfer of immediately available
funds to an account designated by ISC in writing.

          Section 5.2  Incentive Payments.
                       -------------------

(a)  If the cumulative sum of the AUCS Entities' Adjusted EBITDA Losses over the
Initial Term is below Euro 295,317,000 (two hundred and ninety five million
three hundred and seventeen thousand Euro) in the aggregate (the "Incentive
                                                                  ---------
Target"), ISC will receive as an incentive payment 100% of such difference
- ------
below Euro 295,317,000 (two hundred and ninety five million three hundred and
seventeen thousand Euro) from Unisource, such payment to be made by Unisource to
ISC by wire transfer of immediately available funds in Euro to an account
designated by ISC in writing within 30 days of the agreement, deemed agreement
or determination by the Accountant of the Closing Date Financial Statements for
the Initial Term in accordance with Section 5.2(c).

                                       6
<PAGE>

(b)  If the cumulative sum of the AUCS Entities' Adjusted EBITDA Losses over the
Initial Term exceeds the Incentive Target, then ISC shall rebate to AUCS (or as
otherwise directed by the Supervisory Board) such part of the Management Fees
paid or payable during the Initial Term as are equal to 25% of the aggregate of
the AUCS Entities' Adjusted EBITDA Losses, during the Initial Term which are in
excess of the Incentive Target, provided that such rebate shall never exceed the
Management Fee received or to be received by ISC.

(c)  Within 90 days following the end of the Initial Term, AUCS shall prepare
and deliver to ISC and Unisource Consolidated Financial Statements for the
Initial Term, and as of the Termination Date accompanied by a statement
setting forth the aggregate AUCS Entities' Adjusted EBITDA Losses, for the
Initial Term ("Closing Date Financial Statements") such Consolidated
               ---------------------------------
Financial Statements shall be subject to the same review, audit and dispute
mechanism resolution procedures set forth in Section 4.1(f) and upon agreement,
deemed agreement or determination by the Accountant shall be conclusive evidence
of (i) the consolidated revenues of the AUCS Entities and (ii) the AUCS
Entities' Adjusted EBITDA Losses, in each case during the Initial Term for the
purposes of calculating the amounts payable pursuant to Sections 5.1 and 5.2.

(d)  Unisource intends to propose to ISC a mechanism whereby ISC will be
incentivized to minimize the Restructuring Costs (if any).

          Section 5.3    Letters of Credit.
                         ------------------

(a)  The Indirect AUCS Stockholders shall establish with a major reputable bank
in the Netherlands reasonably acceptable to ISC letters of credit (unless as
otherwise agreed between the Indirect AUCS Stockholders and ISC that some other
form of facility be provided offering ISC similar comfort) in favor of AUCS for
the duration of this Agreement in a form acceptable to ISC (the "Letters of
                                                                 ----------
Credit"). Each quarter, the Indirect AUCS Stockholders shall adjust the Letters
- -------
of Credit so that the amount of funds available under such Letters of Credit is
at least equal, in the aggregate, to Euro 42,662,000 (forty two million six
hundred and sixty two thousand Euro) during the first year of the Initial Term
and an equal amount in the second and third years of the Initial Term unless, in
respect of the second and third years, the Indirect AUCS Stockholders and ISC
agree to lower such amount or waive the obligation of the Indirect AUCS
Stockholders under this Section 5.3(a) in respect of such period as the Indirect
AUCS Stockholders and ISC may in their discretion agree.

(b)  AUCS may draw down funds from the Letters of Credit as required to satisfy
any Funding Requirements or Capital Expenditure which, in each case, has not
been paid by Unisource in a timely manner in accordance with Sections 4.1(d) and
4.2(b) as the case may be.

          Section 5.4  Payment of Funding Requirements.  The Funding
                       --------------------------------
Requirements shall be paid to AUCS in the form of loans made available on arm's
length terms by Unisource to AUCS for each quarter to cover the envisaged
Funding Requirements for that quarter. All quarterly loans (including accrued
interest) shall terminate at the end of the calendar year. New loans will be
made immediately following such terminations for an aggregate amount equivalent
to the aggregate amount of the loans so terminated, except to the extent that
any such loans are converted into equity in accordance with the following
sentence. Any outstanding loans made

                                       7
<PAGE>

under this Section 5.4 shall, at the end of a calendar year, be converted into
equity and contributed to the capital of AUCS as required such that the
consolidated interest bearing debt of the AUCS Entities is equal to the equity
in the Consolidated Financial Statements or any higher proportion of equity as
is necessary to ensure that (i) the AUCS Entities are solvent and continue
trading under all relevant laws and rules and (ii) the statutory auditors of the
AUCS Entities are able to deliver an unqualified audit opinion under Dutch GAAP
(or other applicable national GAAP).

- -------------------
of any claim as to which indemnity may be sought, and the Indemnified Party

Party to give notice as provided herein shall not relieve the Indemnifying Party
of its indemnification obligation under this Agreement except to the extent that
such omission results in a failure of actual notice to the Indemnifying Party
and such Indemnifying Party is materially damaged as a result of such failure to
give notice.  Except with the prior written consent of the Indemnified Party, no

<PAGE>

as an unconditional term thereof the giving by each claimant or plaintiff to
such Indemnified Party of a release from all liability with respect to such
claim or litigation. In the event that the Indemnified Party shall in good faith
determine that the conduct of the defence of any claim subject to
indemnification hereunder or any proposed settlement of any such claim by the
Indemnifying Party might be expected to affect adversely the Indemnified Party's
tax liability or the ability of Indemnified Party to conduct its business, or
that the Indemnified Party may have available to it one or more defences or
counterclaims that are inconsistent with one or more of those that may be
available to the Indemnifying Party in respect of such claim or any litigation
relating thereto, the Indemnified Party shall have the right at all times to
take over and assume control over the defence, settlement, negotiations or
litigation relating to any such claim at the sole cost of the Indemnifying
Party. In the event that the Indemnifying Party does not accept the defence of
any matter as above provided, the Indemnified Party shall have the full right to
defend against any such claim or demand and shall be entitled to settle or agree
to pay in full such claim or demand. In any event, the Indemnifying Party and
the Indemnified Party shall cooperate in the defence of any claim or litigation
subject to this Section 9.4 and the records of each shall be available to the
other with respect to such defence.

between ISC and an AUCS Entity, the matter shall be discussed between the
chief executive officers of ISC and Unisource), is not resolved by the said
chief executive officers within a maximum of 14 days, the dispute shall be
referred to and finally resolved by arbitration under the London Court of
International Arbitration ("LCIA") Arbitration Rules, which Arbitration

be the LCIA.  The number of arbitrators shall be three and such arbitrators
to include persons experienced in European telecommunications (the

(e)  The Arbitrators shall have authority to award interest on any amount
awarded by the Arbitrators up to the date of that award at the rate equal to 1
(one) percentage point above the three month EURIBOR rate for Euros from time to

paid within 14 days of publication of that decision, interest will thereafter
accrue on the amount at the rate equal to 2 (two) percentage points above the
three month EURIBOR rate for Euros from time to time.

(f)  The referral of a dispute to arbitration under Section 10.2(b) shall not
preclude any Party from obtaining interim relief on an urgent basis from a
court of competent jurisdiction pending any decision of the Arbitrators.

the Parties, and the Parties agree to exclude, so far as lawfully possible
to exclude, any right of application or appeal to the English (or other)
courts in connection with any question of law arising in the arbitration or
in connection with any award or decision made by the Arbitrators, except as
may be necessary to enforce such award or decision.

cause or will cause Infonet to have any fiduciary, trustee or similar
obligations to the AUCS Entities, Unisource, UPES or the Indirect AUCS
Stockholders.

          Section 10.5  Validity.  If any provision of this Agreement is found
                        ---------
or held to be invalid or unenforceable, the validity of all the other provisions
hereof shall not be affected thereby and the parties agree to meet and review
the matter and if any valid and enforceable means is reasonably available to
achieve the same object as the invalid or unenforceable provision, to adopt such
means by way of variation of this Agreement. However, if any invalid term is
capable of amendment to render it valid, the parties agree to negotiate an
amendment to remove the invalidity.

          Section 10.6  Due Diligence.  Prior to the date hereof, ISC has,
                        --------------
directly or through its representatives, reviewed the properties, books and
records of AUCS listed on the Data Room Index initialed by the Parties ISC and
Unisource comprising Exhibit 10.6 and their financial and legal condition to the
extent that it has deemed necessary or advisable to familiarize itself with the
properties and other matters related to the AUCS Entities; such review shall
not, however, affect the representations or warranties made by the AUCS
Entities, the Unisource Entities and the Indirect AUCS Stockholders herein, or
the remedies of ISC for the breach of those representations and warranties.

          Section 10.7  Severability.  In the event that any of the terms of
                        -------------
this Agreement are found to be invalid, unlawful or unenforceable, such terms
(provided that they are not fundamental to the agreement) shall be severable
 --------
from the remaining terms, which shall continue to be valid and enforceable.

          Section 10.8  Variation.  No variation of or addition to this
                        ----------
Agreement shall be of any force or effect unless reduced to writing, signed by
or on behalf of Unisource (on behalf of all the Unisource Entities and the
Indirect AUCS Stockholders), AUCS N.V. (on behalf of all the AUCS Entities) and
ISC and expressed to amend this Agreement.

          Section 10.9  Entire Agreement.  This Agreement (including the
                        -----------------
documents referred to in it) replaces all prior agreements and arrangements
between the Parties and constitutes the entire understanding between the parties
relating to the subject matter of this Agreement. Each Party acknowledges that
in agreeing to enter into this Agreement it has not relied on any
representations, warranties or promises (except those set out in this Agreement)
made by or on behalf of the other Parties before the signature of this
Agreement. Each Party

                                      17

waives all rights and remedies which, but for this Section, might otherwise be
available to it in respect of any such representation, warranty or promise,
provided that nothing in this Section shall limit or exclude any liability for
fraud.

          Section 10.10  Waiver.  A waiver by the Parties of a breach of any
                         -------
term or condition of this Agreement in any one instance shall be in writing and
shall not be deemed as a continuing waiver or a waiver of any other or
subsequent breach unless the written notice so provides.

prepare and deliver to ISC and Unisource Consolidated Financial Statements
audited for Unisource consolidation purposes (to the extent historically done by
AUCS) and a statement of the AUCS Entities' Adjusted EBITDA Losses for such
calendar year. In the event of any dispute between ISC and Unisource as to such
Consolidated Financial Statements or the statement of the AUCS Entities'
Adjusted EBITDA Losses, they shall be subject to the same review, and dispute
resolution procedures set forth in Section 4.1(f).

          Section 12.4  Agreements with Infonet.  During the Term, Infonet
                        -----------------------

negotiated and entered into on an arms-length basis. Not more than once in any
calendar year, during the Term, Unisource may, at its own cost and expense,

compliance with this Section 12.4.

exceeded and Unisource determines to liquidate the AUCS Entities or if within 30
days following the termination of this Agreement for any reason Unisource
decides to liquidate the AUCS Entities on a solvent basis, Unisource shall have
the right to request and upon such request ISC shall provide management support
to the AUCS Entities in connection with such liquidation, subject to the Parties
agreeing reasonably acceptable terms, including appropriate payment and

of the AUCS Entities and the Unisource Entities and all liabilities of Infonet
incurred in connection therewith.

                       AUCS & INFONET IMPLEMENTATION PLAN
                                     DRAFT
1.      Summary
        -------

Infonet plans to undertake a review of all AUCS operations over the first 90
days in order to formulate a business plan to meet the objectives agreed with
KPN, Swisscom and Telia.  During this review period Infonet proposes regular
consultation and meetings with the Works Council so that there will be ongoing
input in the decision process.  After this review period Infonet will then
implement the plan.

2.      Consulting and Planning Phase
        -----------------------------

2.1.    General
        -------

Although as a result of the due diligence effort and our long standing business
relationship, Infonet has a general understanding of the AUCS organization and
product offering, Infonet also knows that such general knowledge is not a
sufficient base to formulate a sound and detailed enough business plan.

As such Infonet plans to do a detailed on-site review of the total AUCS
organization during Step 1 of the initial phase.  This Step 1 is planned to take
up to 60 days.

Step 2 of this initial phase will be the preparation for implementation of the
business plan.  This Step 2 is planned to take up to an additional 30 days.

It is planned that during this initial phase there will be a consulting process
with the Works Council at least on a monthly base.

2.2.    Step 1 (Day 1 - Day 60)
        -----------------------

2.2.1.  Initial Staff update and ongoing information

On Day 1 it is planned to call a plenary meeting of all AUCS staff in order to
present Infonet, its senior management and to explain the agreements reached and
the general planning as outlined in this document.

The Infonet management team that will be involved on site during this initial
review will be presented as well as their general areas of responsibility.

It will be announced that after the initial Consulting and Planning Phase a new
plenary meeting will be held where the general vision and outline of the
business plan will be announced.

The name of a contact person will be provided to whom any questions can be
directed during this period that relate to a better understanding of the process
or the agreements made.

                                      xiv
<PAGE>

2.2.2.  AUCS management team

As early as possible in the process the onsite Infonet management team will do a
joint planning session with the AUCS management team on how best to understand
the organization, processes, products, current and planned activities.

As part of this process an inventory will be made of the non-standard ongoing
projects and priorities will be assigned taking into account the known synergies
between the companies and the knowledge that Infonet can bring to these
projects.

Also as part of this process it will be clarified in more detail what member of
the Infonet team will review and be involved in what part of the AUCS functional
organization.  Once this is defined the members of the respective AUCS
functional teams will be informed.

2.2.3.  Functional Organization Review

Once the teams are informed, the Infonet member will work with the staff
involved to understand the way their line of business is currently operating.
During this process it is planned that all staff members will have the
opportunity to meet and explain their current assignments, other interests and
ideas.

2.2.4.  Business Plan Preparation

Whilst individual functional business plans will be created as a result of these
reviews there will be a constant feedback to the senior management planning team
that will review this ongoing input and provide a cross functional view leading
to a joint business plan.

It is planned to have a first outline plan ready after 30 days, followed by
weekly revisions afterwards, resulting in a final plan after 60 days.

2.2.5.  Works Council Consultation

It is planned to inform and review the first outline plan (i.e. after 30 days)
with the Works Council and get their input as part of the ongoing planning
process.

The Works Council will also be consulted at the end of the week before the final
plan.

Upon finalization of the plan, the Works Council will be informed and planning
will be done for the joint responsibilities during Step 2 of the initial phase.

It is understood that if during this period substantial changes have to be made
to this Implementation Plan the Works Council shall be consulted as soon as
practical possible.

                                      xv
<PAGE>

2.2.6.  Administration and Billing

As a result of the agreements that will be in place, certain changes will be
required with respect to the billing structure as well as some additional
reporting requirements.  These will be addressed and start implementation as
soon as possible in the process.

2.3.    Step 2 (Day 61 - Day 90)
        ------------------------

The management teams will during this period start the implementation planning
for the business plan.

In as far as the result of the business plan shows an overstaffing in certain
areas, the management team will work together with the Works Council to prepare
a fair Social Plan - a draft outline was on request of the AUCS senior
management already prepared at this stage.

2.4.    Staff Information
        -----------------

As announced during the first plenary meeting a new meeting will be organized
and the outline and main ideas of the business plan will be presented to all
staff.

The name of a contact person will also be provided to whom additional questions
can be raised during the days following this meeting.

3.      Implementation Phase
        --------------------

All staff will now start towards the implementation of the business plan.
Performance against plan will be measured on a monthly base and at least on a
quarterly base be communicated to the staff.

4.      Business Plan Review
        --------------------

It is planned to review the Business Plan at least every 6 months in order to
update it to the then current situation.  The Works Council will be informed of
such updates and consulted in case this should result in major changes.

5.      Open Door Policy and Infonet Priorities
        ---------------------------------------

It will be made clear as of day one that the Infonet management style is a very
similar hands on open door approach.  Infonet is always looking for ideas,
suggestions, and comments and will share information as much as possible.

                                      xvi
<PAGE>

The priorities as communicated by Infonet senior management to its staff since
years are:

    .  Meet financial and operational commitments on a consistent basis.
    .  Increase pretax margins to the level of profitability to fuel future
       growth.
    .  Provide a customer perceived level of service that is unmatched in our
       industry.
    .  Establish a customer oriented working climate that supports risk taking,
       creativity, fairness, team spirit and mutual respect.
    .  Attract, train and retain top quality personnel.
    .  Provide the opportunity for stable employment through the steady growth
       of the company.

transaction between Infonet and AUCS.  Although it has been prepared in good
faith and is indicative of the current thinking, it is not a legally binding

Unisource, AUCS or Infonet can accept any liability to any person in connection
with this document or its contents.

                            AUCS SOCIAL PLAN OUTLINE

                                     Draft

1.  General
    -------

Although the business planning as defined in the AUCS & INFONET Implementation
Plan will first need to be conducted, it is acknowledged that the restructuring
as a result of the proposed transaction may result in redundancies.

Although management does not know if and what the redundancies will be, nor the
re-employment possibilities, it does understand the potential concerns and would
like to share its current thinking in order to confirm, that in such case this
will be handled professional and in a spirit of mutual respect.

As indicated in the Implementation Plan there will be regular consultation with
the Works Council and if such case should arise a detailed Social Plan will be
developed and reviewed.

The following represents the basic provisions that are seen at this stage.

2.  Basic Provisions
    ----------------

 .  If appropriate, staff will be reassigned between AUCS functional
   organizations.
 .  In case this is not appropriate, assignment within KPN, Telia, Swisscom,
   Infonet or an affiliated company will be explored.
 .  In case this is not appropriate an outplacement program will be considered
   and developed.
 .  In case staff is not covered by any of the above, fair redundancy
   arrangements will be made in line with the jurisdictions in force.

3.  Guidance and Monitoring
    -----------------------

Professional local advisor will in such case, in addition to the consultations
with the Works Council, be used to advise management on the correct legal and HR
procedures as well as the content of the social plan.

Management envisages that, during a to be agreed upon time, resources would be
made available to provide guidance and consultancy to staff affected.

platform, services, equipment or customer support which are used to provide
Contract Services to Non-AT&T Customers pursuant to Contracts or New Contracts
with Infonet's products, platforms, services, equipment or customer support as
determined by Infonet; provided that the replacement products, platforms,
                       --------
services, equipment or customer support provided shall be permitted under the
relevant Contract or New Contract or be otherwise satisfactory to such affected
Non-AT&T Customer.

Stockholders shall maintain their resources insofar as necessary to satisfy
their obligations under their respective Contracts.

     2.7  The Parties hereby consent to Infonet contracting with any Non-AT&T
Customer to provide any services.  The Parties acknowledge that this may result
in the termination of existing commercial relationships between the AUCS
Entities and any Non-AT&T Customer and shall raise no objection to any such
termination.  The Parties agree that from time to time ISC and Infonet may
terminate or amend any such contracts that they enter into with any Non-AT&T
Customer but always observing the terms of the contract with such Non-AT&T
Customer.

     2.8  The Parties shall use all reasonable endeavors to cause the Non-AT&T
Customers to enter into such documents as are necessary to evidence the
assignments and transfers described in this Article 2, including amending the
Contracts with distributors to non-exclusive arrangements.

     2.9  After the Effective Date, the AUCS Entities shall hold any payments
received by any of them from any customer as payment for services provided by
Infonet in trust for ISC in a bank account or accounts to be specified by ISC.
No AUCS Entity shall withdraw any monies from such aforementioned accounts
without the prior approval of ISC and shall pay over such monies to ISC at ISC's
request.

     (a)  Subject to Section 4.1 above, ISC indemnifies and holds harmless the
Unisource Entities, the AUCS Entities and the Indirect AUCS Stockholders, and
their respective officers, directors, employees and agents (individually, an
"AUCS Indemnified Party" and, collectively, the "AUCS Indemnified Parties" and

together with the ISC Indemnified Parties, the "Indemnified Parties") from and

against any and all Losses incurred by such AUCS Indemnified Party or AUCS
Indemnified Parties by reason of, or resulting from, the breach of any
representation, warranty or covenant made by ISC in this Agreement, provided
                                                                    --------

          ---------------------------
third party against an Indemnified Party, notice shall be given by the
Indemnified Party to the party required to provide indemnification (the
"Indemnifying Party") promptly after such Indemnified Party has actual knowledge
 ------------------
of any claim as to which indemnity may be sought, and the Indemnified Party
shall permit the Indemnifying Party (at the expense of such Indemnifying Party)
to assume the defence of any claim or any litigation resulting therefrom;
provided that (i) the counsel for the Indemnifying Party who shall conduct the
- --------
defence of such claim or litigation shall be reasonably satisfactory to the
Indemnified Party, (ii) the Indemnified Party may participate in such defence at
such Indemnified Party's expense, and (iii) the omission by any Indemnified
Party to give notice as provided herein shall not relieve the Indemnifying Party
of its indemnification obligation under this Agreement except to the extent that
such omission results in a failure of actual notice to the Indemnifying Party
and such Indemnifying Party is materially damaged as a result of such failure to
give notice. Except with the prior written consent of the Indemnified Party, no
Indemnifying Party, in the defence of any such claim or litigation, shall
consent to entry of any judgment or enter into any settlement that provides for
injunctive or other non-monetary relief affecting the Indemnified Party or that
does not include as an unconditional term thereof the giving by each claimant or
plaintiff to such Indemnified Party of a release from all liability with respect
to such claim or litigation. In the event that the Indemnified Party shall in
good faith determine that the conduct of the defence of any claim subject to
indemnification

                                       8
<PAGE>

hereunder or any proposed settlement of any such claim by the Indemnifying Party
might be expected to affect adversely the Indemnified Party's tax liability or
the ability of Indemnified Party to conduct its business, or that the
Indemnified Party may have available to it one or more defences or counterclaims
that are inconsistent with one or more of those that may be available to the
Indemnifying Party in respect of such claim or any litigation relating thereto,
the Indemnified Party shall have the right at all times to take over and assume
control over the defence, settlement, negotiations or litigation relating to any
such claim at the sole cost of the Indemnifying Party. In the event that the
Indemnifying Party does not accept the defence of any matter as above provided,
the Indemnified Party shall have the full right to defend against any such claim
or demand and shall be entitled to settle or agree to pay in full such claim or
demand. In any event, the Indemnifying Party and the Indemnified Party shall
cooperate in the defence of any claim or litigation subject to this Section 4.4
and the records of each shall be available to the other with respect to such
defence.

5. MISCELLANEOUS

     5.1  Governing Law and Arbitration.
          ------------------------------

     (a)  This Agreement shall be governed by and shall be construed in
accordance with English law, without reference to the choice of law provisions
thereof. Accordingly any dispute arising out of or having any connection with
this Agreement shall be decided exclusively in accordance with English law;
provided that all such disputes shall be referred, in the first instance, to the
- --------
respective chief executive officers of the Parties for resolution.

     (b)  If a dispute, after having first been discussed by the chief executive
officers of each of the relevant Parties (provided that if the dispute is
                                          --------
between ISC and an AUCS Entity, the matter shall be discussed between the chief
executive officers of ISC and Unisource), is not resolved by the said chief
executive officers within a maximum of 14 days, the dispute shall be referred to
and finally resolved by arbitration under the London Court of International
Arbitration ("LCIA") Arbitration Rules, which Arbitration Rules are deemed to be
incorporated by reference to this Section 5.1(b).

     (c)  Any arbitration commenced pursuant to Section 5.1(b) shall be
administered by the LCIA and the standard LCIA administrative procedures and
schedule of costs shall apply. In any such arbitration, the appointing authority
shall be the LCIA. The number of arbitrators shall be three and such arbitrators
to include persons experienced in European telecommunications (the
"Arbitrators"). The place of arbitration shall be London and the language used
 -----------
in the arbitral proceedings shall be English. The governing law of the Agreement
shall be the substantive law of England.

     (d)  The fees of the Arbitrators, the costs of the LCIA and the cost of the
other parties relating to the arbitration (including, but not limited to, the
reasonable costs of professional advisers) shall be borne by those Parties
against whom the Arbitrators make any award in the proportion of any such award.

     (e)  The Arbitrators shall have authority to award interest on any amount
awarded by the Arbitrators up to the date of that award at the rate equal to 1
(one) percentage point above the

                                       9
<PAGE>

three month EURIBOR rate for Euros from time to time. If any amount payable as a
result of a decision of the Arbitrators is not paid within 14 days of
publication of that decision, interest will thereafter accrue on the amount at
the rate equal to 2 (two) percentage points above the three month EURIBOR rate
for Euros from time to time.

     (f)  The referral of a dispute to arbitration under Section 5.1(b) shall
not preclude either party from obtaining interim relief on an urgent basis from
a court of competent jurisdiction pending any decision of the Arbitrators.

     (g)  Any decision of the Arbitrators shall be final, conclusive and binding
on the parties, and the parties agree to exclude, so far as lawfully possible to
exclude, any right of application or appeal to the English (or other) courts in
connection with any question of law arising in the arbitration or in connection
with any award or decision made by the Arbitrators, except as may be necessary
to enforce such award or decision.

     (h)  The provisions of this Section are severable from the rest of this
Agreement and shall remain in effect despite any invalidity for any reason of
this Agreement.

     5.2  General Cooperation; Further Assurances. Each Party, at its expense,
          ----------------------------------------
shall promptly and duly execute and deliver to the other Parties such further
documents and assurances and take such further action as the other Parties may
from time to time reasonably request in writing in order to carry out more
effectively the intent and purpose of this Agreement (including, without
limitation, any applications, documents and reports required by any governmental
authority).

     5.3  Confidential Information.  While this Agreement is in effect and for a
          -------------------------
period of 36 calendar months thereafter the Parties will hold in confidence the
terms and provisions of this Agreement, the Contracts and the New Contracts
(collectively the "Confidential Information").  The Parties hereby acknowledge
                  --------------------------
and agree that the Confidential Information is confidential and proprietary and
is not to be disclosed to third persons without the prior written consent of
both AUCS and ISC.  The Parties shall not disclose such Confidential Information
to any third party (other than to officers, directors, employees and agents of
AUCS and ISC, each of whom is bound by this Section 5.3) except:

     (a)  to the extent necessary to comply with applicable law or the valid
order of a governmental agency or court of competent jurisdiction; provided,
                                                                   --------
however, that the Party making such disclosure shall seek confidential treatment
- -------
of said information from such third parties;

     (b)  as part of its normal reporting or review procedure to regulatory
agencies, its parent company, its auditors and its attorneys; provided that the
Party making such disclosure to any such regulatory agency shall give the other
party advance written notice of any disclosure, shall seek confidential
treatment of such information and shall use commercially reasonable efforts to
cooperate with the other party in seeking confidential treatment of such
information; provided that any other third party (not being a regulatory agency)
to whom disclosure is made agrees to the confidential treatment of such
information;

                                       10
<PAGE>

     (c)  in order to enforce its rights and perform its obligations pursuant to
this Agreement, including obtaining any necessary government authorizations with
respect to this Agreement;

     (d)  to the extent required by any public offering of securities of ISC in
any jurisdiction;

     (e)  pursuant to the disclosure requirements of the U.S. Securities Act of

any jurisdiction, in each case as amended and the rules and regulations
promulgated thereunder; and

     (f)  to the extent necessary to obtain appropriate insurance, to its
insurance agent; provided that such agent agrees to the confidential treatment
                 --------
of such information.

          In the event that any Party is requested (the "Disclosing Party")
                                                         ----------------
pursuant to, or becomes compelled by, applicable law, regulation or legal
process to disclose any Confidential Information, the Disclosing Party will
provide any non-Disclosing Party with prompt written notice so that any non-
Disclosing Party may seek a protective order or other appropriate remedy.  In
the event that no such protective order or other remedy is obtained, the
Disclosing Party will furnish only that portion of the Confidential Information
which the Disclosing Party is advised by counsel is legally required and
cooperate, at the Disclosing Party's sole cost and expense, with the other
party's efforts to obtain reliable assurance that confidential treatment will be
accorded the Confidential Information.

     5.4  Validity.  If any provision of this Agreement is found or held to be
          ---------
invalid or unenforceable, the validity of all the other provisions hereof shall
not be affected thereby and the Parties agree to meet and review the matter and
if any valid and enforceable means is reasonably available to achieve the same
object as the invalid or unenforceable provision, to adopt such means by way of
variation of this Agreement.  However, if any invalid term is capable of
amendment to render it valid, the Parties agree to negotiate an amendment to
remove the invalidity.

     5.5  Severability.  In the event that any of the terms of this Agreement
          -------------
are found to be invalid, unlawful or unenforceable, such terms (provided that
                                                                --------
they are not fundamental to the agreement) shall be severable from the remaining
terms, which shall continue to be valid and enforceable.

     5.6  Variation.  No variation of or addition to this Agreement shall be of
          ----------
any force or effect unless reduced to writing, signed by or on behalf of
Unisource (on behalf of all the Unisource Entities and the Indirect AUCS
Stockholders), AUCS N.V. (on behalf of all the AUCS Entities) and ISC and
expressed to amend this Agreement.

     5.7  Entire Agreement.  This Agreement (including the documents referred to
          -----------------
in it) replaces all prior agreements and arrangements between the Parties and
constitutes the entire understanding between the Parties relating to the subject
matter of this Agreement. Each Party acknowledges that in agreeing to enter into
this Agreement it has not relied on any representations, warranties or promises
(except those set out in this Agreement) made by or on behalf of the other
Parties before the signature of this Agreement. Each Party waives all rights

                                       11
<PAGE>

and remedies which, but for this Section, might otherwise be available to it in
respect of any such representation, warranty or promise, provided that nothing
in this Section shall limit or exclude any liability for fraud.

     5.8  Waiver.  A waiver by the Parties of a breach of any term or condition
          -------
of this Agreement in any one instance shall be in writing and shall not be

To the Stockholders and Board of Directors of
 Infonet Services Corporation
El Segundo, California

      We have audited the consolidated financial statements of Infonet Services
Corporation and its subsidiaries as of March 31, 1998 and 1999, and for each of
the three years in the period ended March 31, 1999, and have issued our report
thereon dated June 14, 1999 (included elsewhere in this Registration

the responsibility of the Company's management. Our responsibility is to
express an opinion based on our audits. In our opinion, such financial
statement schedule, when considered in relation to the basic consolidated
financial statements taken as a whole, presents fairly in all material respects
