                               PROSPECTUS SUMMARY


    THIS SUMMARY HIGHLIGHTS INFORMATION CONTAINED ELSEWHERE IN THIS PROSPECTUS.
YOU SHOULD READ THE ENTIRE PROSPECTUS CAREFULLY. WORLDWIDE FIBER INC. RECENTLY
HAS BEEN RENAMED 360NETWORKS INC. TO REFLECT OUR GLOBAL FOCUS AND EVOLUTION FROM
CONSTRUCTING NETWORKS TO OFFERING A RANGE OF NETWORK AND VALUE-ADDED SERVICES.
REFERENCES IN THIS PROSPECTUS TO "360NETWORKS," "WE," "OUR" AND "US" REFER TO
360NETWORKS INC. (AND ITS PREDECESSOR) AND ALL OF ITS SUBSIDIARIES AS A COMBINED
ENTITY, EXCEPT WHERE IT IS CLEAR THAT THOSE TERMS MEAN ONLY THE PARENT COMPANY.
INDUSTRY AND MARKET DATA IN THIS PROSPECTUS ARE BASED ON OR DERIVED FROM SOURCES
THAT WE BELIEVE ARE RELIABLE. THERE CAN BE NO ASSURANCE, HOWEVER, AS TO THE
ACCURACY OF THE INDUSTRY OR MARKET DATA.


                                  THE COMPANY


    We are a leading independent, facilities-based provider of fiber optic
communications network products and services. By the end of 2001, we expect our
network to consist of approximately 56,300 route miles:



    - 24,100 route miles in North America (of which more than 12,200 route miles
      have been developed to date);



    - 10,600 route miles in Europe (of which more than 4,900 route miles have
      been developed to date);



    - a 7,600 route mile fully protected undersea cable between North America
      and Europe; and



    - a 14,000 route mile fully protected undersea cable between South America
      and North America.



    We intend to expand our network to provide connectivity on a global basis.
Our network's design uses state-of-the-art optical technologies that we believe
greatly reduce complexity and cost while allowing us to offer increased
reliability and a wide range of products and services. We recently agreed,
subject to execution of definitive agreements, to acquire colocation facilities
in 13 cities in North America and Europe comprising approximately 3.9 million
square feet.



    We offer network services to meet our customers' demands, enable Internet
services and intend to develop products and services that capitalize on the
convergence of telecommunications and high-bandwidth applications and services.



    We believe that there is growing demand for fiber optic capacity and related
network elements to transmit and service high-bandwidth data, voice and video.
This growing demand is being accelerated by new applications and services and by
improvements in "last mile" technology such as digital subscriber line and cable
modems. In this changing market environment, we believe that we are in a
favorable competitive position to satisfy this demand relative to other service
providers due to our low-cost, seamless technologies and consistent network
architecture. We have achieved a low-cost position by:



    - leveraging our construction skills;



    - co-developing and swapping along some corridors of our network;



    - using equity as payment for important elements such as bulk rights-of-way;
      and



    - using optical design and technologies that eliminate layers of equipment
      traditionally required to support legacy systems.



    Our current and targeted customers include new and incumbent
telecommunications service providers, Internet service providers, application
service providers, storage service providers and large organizations with
enterprise network needs. We believe that these customers have a limited choice
of independent service providers capable of offering high-capacity, reliable,
secure and cost-effective services, including enabling Internet services,
between major population centers in North America, Europe and South America. As
a result, we believe that our targeted customers will


                                       1
<PAGE>

buy services from us rather than purchase them from another source or build
these service capabilities themselves. To meet our customers' requirements, we
offer a wide range of services on a scalable basis, including:



    - network services--optical channels, private line transmission,
      packet-based data services such as Internet protocol transport and
      Asynchronous Transfer Mode, and virtual voice trunking; and



    - network infrastructure--dark fiber and conduit for sale, grant of
      indefeasible right of use or lease and construction services supporting
      the development of our network.



    Through the colocation facilities that we have agreed to acquire we will be
able to provide additional network services such as Internet data centers,
applications hosting, electronic commerce support and web hosting. We intend to
expand our business to include additional network services such as video
transport, independent Internet access for transport and peering and management
services to allow carriers to migrate from circuit-switched technologies to
packet-based technologies.



    We expect to enable our customers to establish and maintain a strong
competitive position in providing services to their end users. We believe that
our independence, product design, seamless technology, consistent network
architecture, simple billing systems and end-to-end international connectivity
will enable us to gain a strong market position.


BUSINESS STRATEGY


    To exploit the growing demand for bandwidth and enhanced network services,
our strategy is to:



    - provide high-bandwidth connectivity between, and colocation facilities in,
      major global population centers;


    - develop and operate a technologically advanced, high-capacity, low-cost
      network;


    - extend the reach of our network through development, swaps and
      acquisitions of fiber and capacity;


    - expand our marketing capabilities;


    - increase, in collaboration with our customers, the number of products and
      services that we offer, including managed bandwidth and Internet enabling
      products and services;


    - capitalize on management experience and relationships; and


    - pursue additional strategic alliances in network services and technology.


THE NETWORK


    Our 56,300 route mile network is scheduled to be completed by the end of
2001. We plan to further develop and expand our network footprint in response to
customer demand. Our network consists of fiber optic assets and capacity that we
have installed or acquired from other developers and carriers through swaps,
purchases, leases, indefeasible rights of use or other contractual rights along
diverse rights-of-way.



    - NORTH AMERICA. In North America, our network is expected to cover
      approximately 24,100 route miles, of which more than 12,200 route miles
      have been developed to date, encompassing both long-haul and intra-city
      route miles and providing connectivity among approximately 50 major
      population centers.



    - EUROPE. In Europe, our network is expected to cover approximately 10,600
      long-haul route miles (assuming, with respect to 1,300 route miles, the
      exercise of an option that we have), of which more than 4,900 route miles
      have been developed to date, providing connectivity among approximately 35
      major population centers.


                                       2
<PAGE>

    - 360ATLANTIC UNDERSEA CABLE. Our 7,600 route mile undersea cable between
      North America and Europe will have the capacity to be a 1.92 terabits per
      second self-healing ring that will connect landing sites in Boston,
      Halifax, Dublin and Liverpool and to major gateway cities in Europe and
      North America, including London and New York.



    - 360AMERICAS UNDERSEA CABLE. Our planned 14,000 route mile undersea cable
      between South America and North America will have the capacity to be a
      1.28 terabits per second self-healing ring that will be able to offer
      city-to-city connectivity between 6 major population centers in Brazil,
      Venezuela, Bermuda and Argentina and the United States.



    - FUTURE EXPANSION. We intend to expand our planned network to more
      population centers through the addition of intercity and city ring
      capacity in North America, Europe and South America. We are also reviewing
      opportunities to expand the geographic reach of our network, including
      transpacific connectivity to Asia.



RECENT NETWORK EXPANSION



    EUROPE



    - KPNQWEST. We recently signed an agreement with KPNQwest to acquire
      indefeasible rights of use of fiber on its Southern European network,
      which is expected to be complete in the fourth quarter of 2001.



    - TELIA. We are swapping fiber on part of our North American network for
      fiber on significant parts of Telia's European network, which is expected
      to be complete in the fourth quarter of 2000.



    - TELEWEST. We have executed an agreement to develop with Telewest a
      multi-conduit network from London to Liverpool along diverse routes that
      pass through seven major population centers in England. We expect this
      network to be complete by the fourth quarter of 2000.



    - CARRIER1. We have an agreement with Carrier1 that provides us with
      wholesale capacity from London to 18 major European population centers. We
      also have options from Carrier1 to acquire dark fiber strands in Germany
      and/or wavelengths in France.



    SOUTH AMERICA



    - GLOBENET. In March 2000, we announced a definitive agreement to acquire
      GlobeNet Communications Group Limited, a Bermuda company, for Subordinate
      Voting Shares. GlobeNet is developing the 14,000 route mile undersea cable
      Atlantica-1, which we now call 360AMERICAS, between South America and
      North America.



    COLOCATION FACILITIES



    We have agreed, subject to execution of definitive agreements, to acquire
    colocation facilities in two North American cities, site rights in seven
    other North American cities and colocation facilities in four European
    cities, one of which is operational and three of which are under
    construction. The aggregate purchase price for these acquisitions is
    $439 million, payable in a combination of cash and Subordinate Voting
    Shares, of which $113 million is contingent upon the achievement of
    milestones.



RECENT SIGNIFICANT BANDWIDTH TRANSACTIONS



    - KPNQWEST. We recently signed an agreement with KPNQwest to sell capacity
      on 360ATLANTIC between New York City and London, which we will begin to
      deliver in March 2001.



    - SHAW COMMUNICATIONS. We recently signed a contract with Shaw
      Communications Inc., under which Shaw will lease bandwidth on designated
      segments of our network between


                                       3
<PAGE>

      Edmonton and Toronto and either purchase dark fiber or acquire
      indefeasible rights of use on other network segments for $153 million.



    - PSINET. We recently signed contracts with affiliates of PSINet to deliver
      high-speed bandwidth services on 360ATLANTIC from New York to London and
      to provide multiple dark fiber strands in eastern Canada and the northeast
      corridor of the United States. In addition, we have agreed to grant to
      affiliates of PSINet an indefeasible right of use for bandwidth capacity
      between Vancouver and Chicago, which we will deliver by the end of March
      2000.

                             SUMMARY FINANCIAL DATA


    The summary historical financial data for the year ended March 31, 1996, the
five months ended August 31, 1996, the year ended August 31, 1997 and the nine
months ended May 31, 1998 of our predecessor, the telecommunications division of
Ledcor Industries, are derived from the audited financial statements of the
predecessor division, which have been audited by Deloitte & Touche LLP,
independent auditors.



    Our summary consolidated historical financial data for the period from
February 5, 1998 to December 31, 1998 and year ended December 31, 1999 are
derived from our audited consolidated financial statements, which have been
audited by PricewaterhouseCoopers LLP, independent auditors.



    The unaudited pro forma financial data as at and for the year ended
December 31, 1999 are derived from our audited consolidated financial statements
for the year ended December 31, 1999 and the audited consolidated financial
statements of GlobeNet for the year ended December 31, 1999, audited by
PricewaterhouseCoopers LLP, independent auditors, included elsewhere in this
prospectus. The unaudited pro forma income statement for the year ended
December 31, 1999 gives effect to the following transactions as if they occurred
on January 1, 1999:



    - our acquisition of all outstanding stock of GlobeNet;



    - the interest expense on $1 billion of senior notes to be issued in the
      concurrent debt offerings;



    - the interest expense on $500 million of senior notes issued in July 1999;
      and



    - the amortization of goodwill arising from the acquisition of the minority
      equity interests in certain of our subsidiaries.



    The unaudited pro forma as adjusted balance sheet data at December 31, 1999
gives effect to the following transactions as if they occurred on December 31,
1999:



    - the issuance of 44,625,000 Subordinate Voting Shares for net proceeds to
      us of approximately $718 million;



    - our acquisition of all outstanding stock of GlobeNet;



    - the issuance of $1 billion of senior notes in the concurrent debt
      offerings;



    - the acquisition of the minority equity interests in certain of our
      subsidiaries and the related issuance of Series A Non-Voting Preferred
      Shares;



    - the conversion or exchange of our redeemable convertible preferred shares
      into Subordinate Voting Shares and our share capital reorganization;



    - the completion of the $565 million 360ATLANTIC credit facility, of which
      $100 million has been drawn; and



    - the Canadian telecommunications arrangement.



    Our consolidated financial statements, the divisional financial statements
of the predecessor division and the consolidated financial statements of
GlobeNet have been prepared in accordance with U.S. GAAP. The results of
operations for the predecessor division are not comparable to our results of
operations after the telecommunications division of Ledcor was reorganized.



    EBITDA presented in the following table consists of net income (loss) before
interest expense, net of interest income, provision for income taxes,
depreciation, stock-based compensation, amortization of goodwill and income
attributable to minority interest. EBITDA is presented because


                                       7
<PAGE>
we believe that it is a useful indicator of our ability to meet debt service and
capital expenditure requirements. It is not intended as an alternative measure
of operating results or cash flow from operations (as determined in accordance
with generally acceptable accounting principles). EBITDA is not necessarily
comparable to similarly titled measures for other companies and does not
necessarily represent amounts of funds available for management's discretionary
use.


    For purposes of calculating the ratio of earnings to fixed charges, earnings
consists of earnings (loss) before equity income, provision for income taxes,
income attributable to minority interest, amortization of goodwill and fixed
charges. Fixed charges consists of interest expensed and capitalized, the
portion of rental expense which we believe to be representative of interest
(assumed to be one-third of rental expense) and pre-tax earnings required to
cover the accretion on the redeemable convertible preferred shares. Pro forma
loss for the year ended December 31, 1999 would have been insufficient to cover
fixed charges by approximately $171 million.



    Capital expenditures represent actual cash expenditures incurred during the
period and do not include acquisitions of assets for non-cash consideration.
Route miles represent the number of miles spanned by fiber optic cable owned by
us or in respect of which we have acquired capacity pursuant to swaps, leases,
indefeasible rights of use or other contractual rights at the end of the period,
calculated without including physically overlapping segments of cable.



    The following table presents summary consolidated financial data derived
from our consolidated financial statements. You should read the following
information along with "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and the financial statements and the
related notes included elsewhere in this prospectus.

(1) To compute basic and fully diluted loss per share, net income of $23,640,000
    is reduced by a stock dividend of $5,000,000, the accretion on the Series A
    Non-Voting Preferred Shares of $6,465,000 and an amount of $22,070,000 which
    represents the fair value of the Series A Non-Voting Preferred Shares issued
    to the existing shareholders for no additional consideration as a result of
    anti-dilution provisions in the original subscription agreement, resulting
    in a net loss to holders of Subordinate Voting Shares and Multiple Voting
    Shares of $9,895,000.

                                  RISK FACTORS


    You should carefully consider the risks described below before deciding
whether to invest in our Subordinate Voting Shares. The risks and uncertainties
described below are not the only ones we face. Additional risks and
uncertainties not presently known to us may also impair our business operations.



    If we do not successfully address any of the risks described below, there
could be a material adverse effect on our business, financial condition or
results of operations. As a result, the trading price of our Subordinate Voting
Shares may decline and you may lose all or part of your investment. We cannot
assure you that we will successfully address these risks.


GENERAL BUSINESS

LIMITED HISTORY OF OPERATIONS--GIVEN OUR LIMITED OPERATING HISTORY, YOU SHOULD
CONSIDER OUR SHARES TO BE A HIGHLY SPECULATIVE INVESTMENT.


    You have very limited historical financial information upon which to base
your evaluation of our performance and an investment in our Subordinate Voting
Shares. We began operations as an independent company in May 1998 and have a
limited operating history. Before that time we conducted business as the
telecommunications division of Ledcor Industries. We believe that our financial
results are not directly comparable to theirs. You must consider our prospects
in light of the risks, expenses and difficulties frequently encountered by
companies in an early stage of development.


RISKS ASSOCIATED WITH DEVELOPMENT AND EXPANSION OF OUR NETWORK--OUR INABILITY TO
IMPLEMENT OUR BUSINESS STRATEGY AND MANAGE OUR GROWTH COULD IMPAIR OUR OPERATING
RESULTS.

    Successful implementation of our business strategy depends on numerous
factors beyond our control, including economic, competitive and other conditions
and uncertainties, the ability to obtain licenses, permits, franchises and
rights-of-way on reasonable terms and conditions and the ability to hire and
retain qualified personnel. Adverse economic or competitive conditions or the
failure to obtain the necessary authorizations or to hire and retain qualified
personnel could prevent or delay the completion of all or part of our network or
increase completion costs. In order to implement our proposed business strategy,
we must accomplish the following in a timely manner at a reasonable cost to us
and on acceptable conditions:

    - obtain continued access to capital markets;

    - design, engineer and operate fiber networks;

    - install fiber optic facilities, transmission equipment and related
      infrastructure;

    - acquire additional rights-of-way;


    - swap, lease, purchase or obtain other contractual rights in additional
      fiber optic facilities;


    - attract and retain high-quality operating personnel and management; and

    - continue to implement and improve our operational, financial and
      accounting systems.

    In addition, construction of future networks entails significant risks,
including:

    - management's ability to effectively control and manage these projects;

    - shortages of materials, equipment or skilled labor;

    - unforeseen engineering, environmental or geological problems; and

                                       11
<PAGE>
    - work stoppages, weather interference, floods and unanticipated cost
      increases.

    We cannot assure you that the anticipated costs of our current and future
projects will not be exceeded or that these projects will commence operations
within the contemplated schedules, if at all.


    Our success will depend, to a significant degree, upon our ability to secure
a market for our network capacity and obtain and maintain contractual and other
relationships with telecommunications service providers, Internet service
providers, application service providers, storage service providers and large
organizations with enterprise network needs. If we are unable to enter into
contracts, comply with the terms of contracts or maintain relationships with
these constituencies, our operations would be materially and adversely affected.
Some of our current contracts to supply fiber capacity allow the buyer or lessee
to terminate the contracts and provide for liquidated damages if we do not
supply the stated fiber capacity by a specified time. Terminating any of these
contracts could adversely affect our operations.



    Additionally, we expect to significantly expand the range of services that
we offer. This expansion includes providing various network services to carriers
and other service providers. We may enter into joint ventures where we or our
partners supply the venture with dark fiber and the appropriate optical
transmission equipment by facilitating the involvement of third party suppliers,
vendors and contractors. We cannot assure you that a market will develop for our
new services, that implementing these services will be technically or
economically feasible, that we can successfully develop or market them or that
we can operate and maintain our new services profitably.


    In order to reach our operating and financial goals, we must substantially
increase the current volume of voice, data, Internet and video transmission on
our network. If we do not develop long-term commitments with new large-volume
customers as well as maintain our relationships with current customers, we will
be unable to increase traffic on our network, which would adversely affect our
profitability.

RISK OF NETWORK FAILURE--NETWORK DISRUPTIONS COULD ADVERSELY AFFECT OUR
OPERATING RESULTS.

    Our success will require that our network provide competitive reliability,
capacity and security. Some of the risks to our network and infrastructure
include:

    - physical damage;

    - power loss;

    - capacity limitations;

    - hardware and software defects;

    - excessive sustained or peak user demand;

    - breaches of security; and

    - disruptions beyond our control.

    These disruptions may cause interruptions in service or reduced capacity for
customers, any of which could have an adverse effect on our ability to retain
customers.


    The sale or lease of network services will require the addition of
transmission equipment to our network. The network will use a combination of
communications equipment, software, operating protocols and proprietary
applications for the high speed transportation of large quantities of digital
signals among multiple locations. Given the complexity of our network, digital
signals may become lost or distorted, which may cause significant losses to our
customers. The network may also


                                       12
<PAGE>

contain undetected design faults and software "bugs" that, despite our testing,
may be discovered only after the network has been completed and is in use. The
failure of any equipment or facility on our network could result in the
interruption of customer service until we make necessary repairs or install
replacement equipment and have an adverse impact on our revenues and our ability
to secure customers in the future. We do not possess adequate insurance to guard
against the losses we could incur as a result of the factors enumerated above.



LIMITED EXPERIENCE--WE HAVE LITTLE EXPERIENCE IN THE OFFERING OF BANDWIDTH AND
VALUE ADDED NETWORK SERVICES AND THIS COULD INCREASE OUR RISK OF FAILURE.



    We expect an increasing portion of our revenues to be derived through our
offering of bandwidth and value added network services. We have limited
experience offering these services. Presently, we derive substantially all of
our revenues from the sale, grant of an indefeasible right of use or lease of
dark fiber and conduit and construction services. See "Business--Customers" and
"--Competition."



PRICING PRESSURES--WE ANTICIPATE THAT PRICES FOR NETWORK SERVICES AND FIBER
ASSETS WILL DECLINE.


    We anticipate that prices for our products and services specifically, and
network transmission capacity in general, will continue to decline over the next
several years, due primarily to the following:

    - price competition as various network providers complete construction of
      networks that will compete with our network;

    - installation by us and our competitors of fiber capacity in excess of
      actual demand;

    - recent technological advances that enable substantial increases in the
      transmission capacity of both new and existing fiber optic networks; and

    - strategic alliances or similar transactions, such as long distance
      capacity purchasing alliances, that increase our customers' purchasing
      power.

NEED FOR RIGHTS-OF-WAY--A FAILURE TO OBTAIN OR MAINTAIN APPROPRIATE
RIGHTS-OF-WAY COULD DELAY THE COMPLETION OF THE NETWORK AND INCREASE ITS COST.


    We cannot assure you that we will be successful in obtaining additional
rights-of-way and other permits required to install underground conduit from
parties such as railroads, utilities, highway authorities and governments and
transit authorities. After we have obtained rights-of-way, we may not be able to
maintain them. Some of our rights-of-way agreements may be short-term or
revocable at will. Some rights-of-way may require regulatory filings or may be
subject to legal challenge by third parties such as municipal governments,
aboriginal citizens or land owners concerning rights-of-way granted for specific
purposes. For example, WFI Urbanlink Ltd. ("Urbanlink"), the Canadian
telecommunications common carrier which has granted IRUs to us of its fiber
optic transmission facilities in Canada for sale on a resale basis, is seeking
an order from the Canadian Radio-television and Telecommunications Commission to
prescribe the terms and conditions of access to street crossings and other
municipal properties in the city of Vancouver. In a related matter, the city of
Vancouver has served the company that provides conduit to Urbanlink for certain
of its facilities located in the city of Vancouver with a notice of termination
for access to street crossings and other municipal property in the city. Failure
on the part of Urbanlink to obtain the order requested in its application to the
Canadian Radio-television and Telecommunications Commission or a renegotiation
of municipal access arrangements with the city of Vancouver by Urbanlink's
conduit provider which results in an increase to the costs of municipal access
could


                                       13
<PAGE>

have a material adverse effect on the business of Urbanlink and, as a result, on
our resale business in Canada. See "Regulation--Canada--CRTC Proceedings."



    In addition, in the United States, landholders who granted rights-of-way to
some railroad companies in the past have filed class action lawsuits against
communications carriers that received rights-of-way from railroad companies in
order to develop their fiber optic networks. The rights-of-way challenged in
these class action lawsuits are similar to some of the rights-of-way that we use
to develop our network, including the rights-of-way granted to us in the
agreements with Canadian National Railway Company and Illinois Central Railroad
Company. Loss of substantial rights and permits or loss of the ability to use
these rights-of-way or the failure to enter into or maintain required
arrangements for the network could have a material adverse effect on our
business, financial condition and results of operations, if, as a result, the
completion of our network is delayed or becomes more costly. See
"Business--Rights-of-way and Permitting."


RISKS ASSOCIATED WITH JOINT VENTURES--OUR BUSINESS STRATEGY CONTEMPLATES
INVESTMENTS IN JOINT VENTURES TO LEVERAGE OUR FIBER ASSETS. THESE INVESTMENTS
MAY INVOLVE SIGNIFICANT RISKS AND OUR CAPITAL ASSETS MAY NOT BE RETURNED.

    We are continually evaluating potential joint ventures and strategic
opportunities to expand our network, enhance our connectivity and add traffic to
our network. Although, except as described in this prospectus, we do not have
any definitive commitment or agreement concerning any material investment,
strategic alliance or related effort, we may seek additional arrangements of
this sort. Any investments, strategic alliances or related efforts are
accompanied by risks such as:

    - the difficulty of identifying appropriate joint venture partners or
      opportunities;

    - the time our senior management must spend negotiating agreements and
      monitoring joint venture activities;


    - the possibility that we may not be able to reach agreement on definitive
      agreements, including for our proposed colocation acquisitions;


    - potential regulatory issues applicable to telecommunications businesses;

    - the investment of our capital or fiber assets and the loss of control over
      the return of this capital or assets;

    - the inability of management to capitalize on the growth opportunities
      presented by joint ventures; and

    - the insolvency of any joint venture partner.

    We cannot assure you that we would be successful in overcoming these risks
or any other problems encountered with these joint ventures, strategic alliances
or related efforts.

RISKS ASSOCIATED WITH INTERNATIONAL MARKETS--WE WILL ENCOUNTER ADDITIONAL RISKS
AS WE PURSUE INTERNATIONAL BUSINESS OPPORTUNITIES.


    Our strategy includes expanding our services to provide fiber optic networks
and network services outside of North America. In particular, we have entered
into an agreement for an undersea cable between North America and Europe called
360ATLANTIC. We have also agreed to acquire GlobeNet, which is constructing an
undersea cable between South America and North America that we call 360AMERICAS.
We also recently announced the expansion of our network into Europe. We


                                       14
<PAGE>

are still evaluating all of the risks associated with these new projects. The
risks associated with 360ATLANTIC and 360AMERICAS include:



    - activities from our competitors which could limit the market share
      obtained by 360ATLANTIC and 360AMERICAS;


    - pricing pressures which could reduce profitability;

    - risk that there will be delay under our supply agreement as a result of
      the highly concentrated nature of the cable manufacturing and installation
      industry; and

    - inability to obtain sufficient pre-construction sales commitments and
      post-construction sales targets.


    Other risks associated with our international plans, including our expansion
into Europe and South America, are:


    - regulatory limitations restricting or prohibiting us from providing our
      services;

    - additional regulatory requirements, tariffs, customs, duties and other
      trade barriers;

    - difficulties in staffing and managing foreign operations;

    - problems in collecting accounts receivable;

    - political risks;

    - fluctuations in the currency exchange and restrictions on the repatriation
      of earnings;


    - delays from customs brokers or government agencies;



    - potentially adverse tax consequences resulting from operating in multiple
      countries with different laws and regulations; and



    - an economic downturn in the countries in which we expect to do business.


    Furthermore, the international rates customers are charged are likely to
decrease in the future for many reasons, including increased competition between
existing carriers, increased competition with new carriers in the international
markets and additional strategic alliances or joint ventures among large
international carriers that facilitate targeted pricing and cost reductions. We
cannot assure you that we will be successful in overcoming these risks or any
other problems arising from operating in international markets.

COMPETITION--OUR BUSINESS IS VERY COMPETITIVE AND INCREASED COMPETITION COULD
ADVERSELY AFFECT US.


    The telecommunications industry is extremely competitive, particularly
concerning price and service. It is relatively common for telecommunications
service providers to be both customers and competitors. This is a concept
referred to as co-opetition. Therefore, we face competition and co-opetition
from existing and planned telecommunications service providers and customers on
each of our planned routes. Our competitors include:



    - interexchange carriers, including AT&T Corp., MCI WorldCom, Inc., Sprint
      Corporation (MCI WorldCom, Inc. and Sprint Corporation have recently
      entered into an agreement to merge), British Telecommunications plc,
      Deutsche Telekom AG, France Telecom S.A. and Qwest Communications
      International Inc.;



    - wholesale providers of terrestrial and undersea connectivity, including
      Williams Communications Group, Inc., Global Crossing Ltd., KPNQwest, N.V.,
      Colt Telecom Group plc and Level 3 Communications, Inc.;


                                       15
<PAGE>

    - incumbent local exchange carriers, which currently dominate their local
      telecommunications markets, including SBC Communications Inc. and
      BellSouth Corporation;



    - competitive local exchange carriers, including NEXTLINK Communications,
      Inc. and Metromedia Fiber Network, Inc.; and



    - companies capable of offering services similar to those provided by us,
      including communications service providers, cable television companies,
      electric utilities, microwave carriers, satellite carriers and wireless
      telephone operators.



    Some of our competitors have already made substantial long term investments
in the construction of fiber optic networks and the acquisition of bandwidth.
Some of these competitors have substantially greater resources and more
experience than we do and could directly compete with us in marketing fiber
assets or network services.


    In addition, some communications carriers and local cable companies have
extensive networks in place that could be upgraded to fiber optic cable, as well
as numerous personnel and substantial resources to begin construction to equip
their networks. If communications carriers and local cable companies decide to
equip their networks with fiber optic cable, they could become significant
competitors of ours in a short period of time.

    Other companies may choose to compete with us in our current or planned
markets, by selling or leasing fiber assets or bandwidth to our targeted
customers. A significant increase in industry capacity or reduction in overall
demand would adversely affect our ability to maintain or increase prices.
Additional competition could materially and adversely affect our operations. See
"Business--Competition."


    Future sources of competition for the 360AMERICAS cable include:



    - Americas-2, a new carriers' consortium cable system with a scheduled ready
      for service date in the first half of 2000 that will connect Brazil,
      Venezuela, Florida and the Caribbean;



    - South American Crossing, a new self-healing ring cable system being
      developed by Global Crossing Ltd. that will link coastal countries in
      South America to Global Crossing's planned Mid-Atlantic Crossing in St.
      Croix, U.S.V.I. and Global Crossing's planned Pan American Crossing in Ft.
      Amador, Panama; and



    - the SAM-I cable system, a self-healing ring cable system being developed
      by Telefonica Internacional S.A. and Tyco International Ltd. that will
      connect the United States, Guatemala, Brazil, Argentina, Chile, Peru and
      Colombia.


DEPENDENCE ON THIRD PARTIES, INCLUDING SUPPLIERS--THE LOSS OF KEY SOURCES OF
SUPPLY COULD ADVERSELY AFFECT US.


    We are dependent upon third party suppliers, including Pirelli Cables and
Systems Inc., for fiber optic cable and a number of components and parts used in
the network, including optical equipment. Recently, some companies have
experienced a shortage of fiber optic cable. We cannot assure you that we will
not experience such a shortage. We are also dependent on Nortel Networks,
Newbridge Networks and Marconi plc for the transmission equipment we need to
offer network services. We believe that there are alternative suppliers or
alternative components for all of the components, including fiber optic cable
and transmission equipment contained in the network or required to offer network
services. However, any delay or extended interruption in the supply of fiber
optic cable or any other key network components, changes in the pricing
arrangements with our suppliers and manufacturers or delay in a transition to a
replacement supplier's product into the network could disrupt our operations. If
the disruption continued for an extended period of time, it could have a
material adverse effect on our business, financial condition and results of
operations.


                                       16
<PAGE>

In addition, we have contracted with Tyco Submarine Systems Ltd. as our primary
contractor for our 360ATLANTIC undersea cable project. Alcatel Submarine
Networks, Inc. is the primary contractor on the 360AMERICAS undersea cable
project. We plan to continue to use third party contractors on various segments
of the network. The failure of the contractors to complete their activities in a
timely manner, within anticipated budgets and in accordance with our quality
standards and performance criteria could have a material adverse effect on our
business, financial condition and results of operations, if, as a result, the
completion of our network is delayed or becomes more costly.


RAPID TECHNOLOGICAL CHANGE--NEW TECHNOLOGIES COULD REDUCE THE DEMAND FOR FIBER
OPTIC SYSTEMS.


    The telecommunications industry generally is subject to rapid and
significant changes in technology that may adversely affect the continued use of
fiber optic cable. Although we have been able to capitalize on some recent
technological advances, such as the use of dense wave division multiplexing to
greatly expand the capacity of our network at constant construction costs, we
cannot assure you that the introduction of new products or the emergence of new
technologies will not enable competitors to install competing systems at a lower
per-circuit cost on routes currently targeted by us. Moreover, these potential
competitors may be able to expand capacity on existing competitive systems,
which could render our network and network services uncompetitive from a cost
perspective. We cannot predict the likelihood of these changes and we cannot
assure you that any technological changes will not materially and adversely
affect our business and operating results.



POTENTIAL CONFLICTS OF INTEREST WITH LEDCOR--WE ARE CONTROLLED BY LEDCOR AND
RELY ON IT FOR PARTICULAR THINGS. ITS INTERESTS MAY CONFLICT WITH YOUR
INTERESTS.



    As of the date of this prospectus, Ledcor holds shares in us which entitle
Ledcor to approximately 90% of the votes attached to our shares and Ledcor has
the ability to control our affairs and business. Ledcor also owns 66 2/3% of the
voting shares of Urbanlink, which owns certain Canadian telecommunications
facilities used by us. See "Relationships and Related Party
Transactions--Transactions with Ledcor--Description of reorganization and
related agreements." This will continue to be the case following the closing of
the offering. It is possible that Ledcor's interests could conflict with your
interests. In addition, Ledcor may have an interest in causing us or Urbanlink
to pursue transactions that, in its judgment, enhance the value of its equity
investment in us or in Urbanlink, even though these transactions may involve
greater risks to you. There can be no assurance that any of these conflicts of
interests will be resolved in your favor.



    In Canada, our network is comprised in part of indefeasible rights of use in
fiber optic transmission facilities obtained from Urbanlink, as part of our
Canadian telecommunications arrangement. Because Urbanlink is controlled by
Ledcor, Urbanlink's interests could conflict with our interests as well as your
own. In addition, because we have no control over Urbanlink's operations, there
can be no assurance that Urbanlink will continue to supply us with fiber optic
transmission facilities and services should we require these facilities and
services from Urbanlink in the future. As part of our Canadian
telecommunications arrangement, we entered into a number of contractual
arrangements with Ledcor. See "Relationships and Related Party Transactions--
Transactions with Ledcor--Description of reorganization and related agreements."



    Ledcor has agreed not to compete with us in the business of developing or
constructing fiber optic communications infrastructure for a period ending on
the earlier of May 31, 2008 and six months after a change of control of
360NETWORKS INC. Ledcor has also agreed to grant to us a worldwide exclusive
license for the use and other exploitation of the railplow technology. The
license will cease to be exclusive six months after a change of control of
360NETWORKS INC. As a


                                       17
<PAGE>

result, if a change of control of 360NETWORKS INC. were to occur, Ledcor would
be legally entitled to compete with us and to grant a license for the use and
other exploitation of the railplow technology to competitors of ours. Either of
these events could have a material adverse effect on our business, financial
condition and results of operations. See "Relationships and Related Party
Transactions--Transactions with Ledcor--Description of reorganization and
related agreements."


LEVERAGE


NEGATIVE CASH FLOWS--GIVEN OUR NEGATIVE CASH FLOWS WHILE OUR NETWORK IS BEING
BUILT, YOU SHOULD CONSIDER AN INVESTMENT IN OUR SUBORDINATE VOTING SHARES TO BE
HIGHLY SPECULATIVE.


    Continued negative cash flow may restrict our ability to pursue our business
strategy. In addition, if we cannot achieve profitability or positive cash flows
from operating activities, we may not be able to meet our debt service
obligations, including our obligations under our existing indebtedness, capital
expenditure requirements or working capital needs.


    We intend to use most of the proceeds from the sale of these Subordinate
Voting Shares to develop and construct our network and expand our network
services business. Until the principal segments of the network are complete, we
will spend more money building the network than we will earn from exploiting it.
Accordingly, we expect to experience negative cash flows after capital
expenditures during network development. We cannot assure you that the
exploitation of our network, including the sale of our fiber and network
services, will result in an adequate revenue base to meet our debt service
obligations or that we will ever generate profitability or positive cash flow.


SUBSTANTIAL LEVERAGE--OUR SUBSTANTIAL DEBT COULD ADVERSELY AFFECT OUR FINANCIAL
HEALTH AND PREVENT US FROM FULFILLING OUR OBLIGATIONS UNDER OUR HIGH YIELD
NOTES.

    We have substantial debt and debt service requirements.

    Our substantial indebtedness could have important consequences to you. For
example, it could:


    - increase our vulnerability to general adverse economic and industry
      conditions;



    - limit our ability to fund future capital expenditures, working capital and
      other general corporate requirements;



    - require us to dedicate a substantial portion of our cash flow from
      operations to make interest and principal payments on our indebtedness,
      reducing the availability of our cash flow to fund capital expenditures,
      working capital and other general corporate purposes;



    - make it more difficult for us to make interest and principal payments on
      our other indebtedness, which would be a default under the indentures;



    - limit our flexibility in planning for, or reacting to, changes in our
      business and the industry in which we operate; and



    - place us at a competitive disadvantage compared to our competitors that
      have less debt. See "Description of Indebtedness." We also intend to
      obtain other sources of financing for the construction of the network,
      including project financing for individual segments of our network. This
      project financing would also be secured by the assets being financed. The

      subsidiaries and the related issuance of Series A Non-Voting Preferred
      Shares;

      into Subordinate Voting Shares and our share capital reorganization; and



    - the completion of the $565 million 360ATLANTIC credit facility, of which
      $100 million has been drawn.



    The initial annual interest expense on the $1 billion of senior notes to be
issued in concurrent debt offerings is $124 million and on the $500 million 12%
senior notes issued in July 1999 is $62 million.



    Pro forma loss for the year ended December 31, 1999 would have been
insufficient to cover fixed charges by approximately $171 million.


ADDITIONAL BORROWINGS REQUIRED--DESPITE OUR CURRENT DEBT LEVEL, WE AND OUR
SUBSIDIARIES MAY INCUR SUBSTANTIALLY MORE DEBT. INCREASED DEBT COULD WORSEN THE
RISKS DESCRIBED ABOVE, BUT FAILURE TO OBTAIN THE DEBT NEEDED COULD PREVENT THE
COMPLETION OF THE NETWORK.

    If additional debt is incurred, the risks mentioned above that are
associated with high leverage will increase. We expect to need significant
amounts of additional capital to complete the development of our planned network
and fulfill our long-term business strategies. The terms of our indentures
generally permit us and our restricted subsidiaries to incur additional debt to
finance the cost of designing and building or acquiring our network. The
indentures also allow us to incur additional indebtedness for other purposes,
subject to some limitations. In addition, the indentures permit us to create
"unrestricted subsidiaries" that will be allowed to incur debt without regard to
the limitations on debt incurrence contained in the indentures. Our ability to
arrange financing and the cost of financing depend upon many factors, including:

    - general economic and capital markets conditions, and in particular the
      non-investment grade debt market;

    - conditions in the telecommunications industry;

                                       19
<PAGE>
    - regulatory developments;

    - investor confidence and credit availability from banks or other lenders;

    - the success of our network; and

    - provisions of tax and securities laws that affect raising capital.

    Our inability to raise additional funds would have an adverse effect on our
ability to complete the network. If we decide to raise additional funds through
the incurrence of debt, we may become subject to additional or more restrictive
financial covenants. In addition, we expect to incur additional debt that is
secured by our assets and therefore those assets will be available to other
creditors before they are available to you.


    We are funding a portion of our anticipated investment in 360ATLANTIC from
our recently completed private sale of our equity securities. We also expect the
indebtedness to finance that project to be incurred by our subsidiary without
recourse to 360NETWORKS INC. We estimate that approximately $565 million of
indebtedness will be required for the 360ATLANTIC project. 360ATLANTIC will be
owned by one or more subsidiaries created for the purpose of owning the project.
They will not hold any assets unrelated to 360ATLANTIC and these subsidiaries
will not be restricted subsidiaries under the indentures. If we were to incur
additional debt at the 360NETWORKS INC. level in order to contribute to the
financing of 360ATLANTIC, however, it would further increase the risks
associated with high leverage.


ABILITY TO SERVICE DEBT--TO SERVICE OUR DEBT WE WILL REQUIRE SIGNIFICANT AMOUNTS
OF CASH AND OUR ABILITY TO GENERATE SUFFICIENT CASH WILL DEPEND ON MANY FACTORS
BEYOND OUR CONTROL.

    We cannot assure you that we will be successful in implementing our strategy
or in realizing our anticipated financial results. You should be aware that our
ability to repay or refinance our debt we incur will depend on our successful
financial and operating performance and on our ability to successfully implement
our business strategy. You should also be aware that our financial and operating
performance depends upon a number of factors, many of which are beyond our
control. These factors include:

    - our ability to complete network development on time and in a
      cost-effective manner;

    - the economic and competitive conditions in the telecommunications
      industry, including the demand for fiber-optic systems;

    - any construction or operating difficulties, increased operating costs or
      pricing pressures we may experience;

    - the passage of legislation or other regulatory developments that may
      adversely affect us; and

    - any material delays in implementing any strategic projects.

    We cannot assure you that our cash flow and capital resources will be
sufficient to repay the notes and any other debt we may incur in the future, or
that we will be successful in obtaining alternative financing. If we are unable
to repay our debts, we may be forced to reduce or delay the completion or
expansion of our network, sell some of our assets, obtain additional equity
capital or refinance or restructure our debt. If we are unable to meet our debt
service obligations or comply with our covenants, a default under our debt
agreements would result. To avoid a default, we might need waivers from third
parties, which might not be granted.

                                       20
<PAGE>
HOLDING COMPANY STRUCTURE--WE WILL DEPEND ON THE CASH FLOW OF OUR SUBSIDIARIES
TO SATISFY OUR OBLIGATIONS UNDER OUR INDEBTEDNESS.


    Our operating cash flow and our ability to service our indebtedness,
including our notes, depends upon the operating cash flow of our subsidiaries
and their payments to us in the form of loans, dividends or otherwise. Our
subsidiaries are separate legal entities and have no obligation to pay any
amounts due on the notes or to make any funds available for that purpose,
whether by dividends, interest, loans, advances or other payments. In addition,
our subsidiaries' payment of dividends and the making of loans, advances and
other payments to us may be subject to regulatory and contractual restrictions.
These restrictions include requirements to maintain minimum levels of working
capital and other assets. Subsidiary payments are contingent upon earnings and
various business and other considerations. As part of the Canadian
telecommunications arrangement we placed certain operating assets in Urbanlink,
which subsidiary we do not and cannot control.


RESTRICTIONS IMPOSED BY TERMS OF OUR INDEBTEDNESS--WE MAY BE UNABLE TO REPAY OUR
INDEBTEDNESS IF THERE IS AN EVENT OF DEFAULT.

    If an event of default occurs under any of our credit facilities or
indentures, the lenders under the credit facilities and the holders of our notes
could elect to declare all amounts outstanding under the credit facilities and
the notes, along with accrued and unpaid interest, to be immediately due and
payable. Our indentures limit, among other things, our ability to incur
additional indebtedness, pay dividends and make certain other restricted
payments, incur liens, enter into some transactions with affiliates and
consummate asset sales and impose restrictions on our ability to merge or
consolidate or sell, assign, transfer, lease, convey or otherwise dispose of all
or substantially all of our assets. In addition, credit facilities that we may
enter into in the future may contain other and more restrictive covenants,
including concerning debt incurrence and the making of capital expenditures and
may require us to meet or maintain specified financial ratios and tests. Our
ability to meet these financial ratios could be affected by events beyond our
control, and no assurance can be given that we will be able to comply with these
provisions. A breach of any of these covenants could result in a default under
these credit facilities and/or the indentures. If we were unable to repay any of
these amounts, the lenders could proceed against any collateral securing the
indebtedness, which could include security interests in all of our future
accounts receivable and inventory and other assets. If the lenders under
potential credit facilities were to accelerate the payment of the indebtedness
under these credit facilities, there would be no assurance that our assets at
the time would be sufficient to repay in full the indebtedness and our other
indebtedness, including the notes.


USE OF PROCEEDS--OUR MANAGEMENT HAS BROAD DISCRETION OVER THE USE OF PROCEEDS
FROM THE OFFERING, AND THEREFORE INVESTORS WILL NOT HAVE THE OPPORTUNITY TO
EVALUATE INFORMATION CONCERNING THE APPLICATION OF PROCEEDS.



    The net proceeds of this offering, together with the concurrent debt
offerings, are estimated to be approximately $1.7 billion after deducting the
estimated underwriting discount and offering expenses. Management will retain
broad discretion as to the use and allocation of those net proceeds.
Accordingly, our investors will not have the opportunity to evaluate the
economic, financial and other relevant information that we may consider in the
application of the net proceeds.

TELECOMMUNICATIONS REGULATION

EXTENSIVE REGULATION--REGULATORY MATTERS COULD IMPACT OUR ABILITY TO CONDUCT OUR
BUSINESS.

    Existing and future governmental regulation may substantially affect the way
in which we conduct business and the procedural and substantive regulatory
requirements with which we must comply. These regulations may increase the cost
of doing business or may restrict the way in which we offer products and
services. There is no way to predict the future regulatory framework of our
business. These regulations are summarized in more detail in the section
entitled "Regulation."

    UNITED STATES

    Federal telecommunications law directly shapes the telecommunications
market. Consequently, regulatory requirements and/or changes could adversely
affect our operations by increasing our costs or restricting the way in which we
offer products and services. Federal telecommunications law imposes special
legal requirements on "common carriers" who engage in "interstate or foreign
communication by wire or radio," and on "telecommunications carriers." The
different ways we intend to offer fiber-optic supported services could trigger
four alternative types of regulatory requirements: (1) non-communications
services, (2) private carrier services, (3) telecommunications services or
common carriage and (4) competitive local exchange carrier offerings. The law
establishing these alternative regulatory requirements is often unclear, so it
is impossible to predict in many instances how the Federal Communications
Commission will classify our services. Risks associated with each type of
offering are described below.

    NON-COMMUNICATIONS SERVICES

    The provision of dark fiber can be viewed as a non-communications service in
that it is not a service, but rather the provision of a physical facility that
is indistinguishable from other non-communications offerings such as the
construction of an office building. Many providers of dark fiber are currently
operating on the assumption that they are providing unregulated facilities.
Nevertheless, the Federal Communications Commission had previously found that
when an incumbent local exchange carrier provided dark fiber it was providing a
common carrier service. A federal appeals court reversed and remanded this
decision to the agency for further proceedings. The Federal Communications
Commission's action in response to this remand could affect our position that
dark fiber is not a communications service.

    PRIVATE CARRIER SERVICES


    Even if some of our offerings are treated as communications services, they
could be viewed as a private carrier offering. Private carrier offerings
typically entail the offering of telecommunications, but are provided to a
limited class of users on the basis of individually negotiated terms and
conditions that do not meet the definition of a telecommunications service under
the Telecommunications Act of 1996. If our services are treated as private
carriage, they are generally unregulated by the Federal Communications
Commission, but would be subject to universal service payments based on the
gross revenues from end users. See "Regulation--United States--
Federal--Telecommunications Services--Universal Service." Private carriers may
also be subject to access charges if they interconnect with local exchange
carriers.


    TELECOMMUNICATIONS SERVICES

    Some of our services, such as the provision of bandwidth capacity and lit
fiber, may be treated as telecommunications services by the Federal
Communications Commission. If any of our services are treated as
telecommunications services, we could be subject to a number of new and
potentially burdensome regulations.

                                       22
<PAGE>
    The precise parameters of the definition of a telecommunications service are
currently unclear. The Federal Communications Commission has held that
telecommunications and common carrier services are essentially the same. Some
railroad, power and telecommunications providers have asked the Federal
Communications Commission to clarify the status of fiber providers. If the
Federal Communications Commission decides that these companies are
telecommunication carriers, we would be subject to certain regulatory
requirements which may impose substantial administrative and other burdens on
us. If any of our services are treated as telecommunications services, we may be
subject to a number of new and potentially burdensome regulations. These general
regulations include the obligation not to charge unreasonable rates or engage in
unreasonable practices, the obligations not to unreasonably discriminate in our
service offerings, the need to tariff our services (subject to the proceeding
described below), the potential obligation to permit others to offer their
services for resale under certain circumstances and the fact that third parties
may file complaints against us at the Federal Communications Commission for
violations of the Communications Act of 1934 or the Federal Communications
Commission regulations. Certain statistical reporting requirements may also
apply. Telecommunications carriers are also required to interconnect, either
directly or indirectly, with the facilities of other telecommunications carriers
and to ensure that they do not install network features, functions or
capabilities that do not comply with Federal Communications Commission
guidelines on accessibility by disabled persons and regulations promoting
interconnectivity of networks. In addition, Federal Communications Commission
rules require that telecommunications carriers contribute to universal service
support mechanisms, the Telecommunications Relay Services fund, the number
portability fund and the North American Numbering Plan Administrator fund. Also,
the Communications Assistance for Law Enforcement Act requires
telecommunications carriers to provide law enforcement officials with
call-related information and reserved circuits. We cannot assure you that the
cost of compliance with these various programs will not have a material adverse
effect upon our results of operations and financial condition and our ability to
meet our obligations.

    The continuation of tariff filing requirements for interstate domestic
services provided by non-dominant carriers is in dispute. The Federal
Communications Commission has ordered that all non-dominant carriers, the
classification we would qualify for, may not file tariffs with the Federal
Communications Commission for domestic service. The D.C. Circuit has stayed the
effect of this decision. Filing tariffs can entail increased costs and may lead
to intrusive regulation by the Federal Communications Commission, although to
date the Federal Communications Commission has engaged in only minor regulation
of non-dominant carriers. On the other hand, if tariffs are no longer required,
telecommunications carriers will no longer be able to rely on the filing of
tariffs with the Federal Communications Commission as a means of providing
notice to customers of prices, terms and conditions on which they offer
interstate services, since tariff provisions limit carriers' liability for
defects in service and consequential damages from such defects. The Federal
Communications Commission has ruled that non-dominant interexchange carriers
must post on their Internet web site their rates, terms and conditions for all
of their interstate, domestic services if they have an Internet web site. This
ruling is to be effective when the decision to mandate de-tariffing takes place.
In addition, if tariffs are eliminated, we may become subject to significantly
increased liability risks, and there can be no assurance that the liabilities
will not have a material adverse effect on our results of operations and
financial conditions and our ability to meet our obligations.

    The Federal Communications Commission adopted rules which govern the use of
customer proprietary network information by telecommunications carriers. These
rules may impede our ability to effectively market integrated packages of
services and to expand existing customers' use of our offerings.

                                       23
<PAGE>
    COMPETITIVE LOCAL EXCHANGE CARRIER OFFERINGS

    It is also possible that some of our lit fiber or bandwidth capacity
services could be viewed as the provision of local exchange service. See
"Regulation--United States--Federal--Competitive Local Exchange Carrier
Offerings." To the extent that any of our offerings are treated as competitive
local exchange carrier services, we would also be subject to a number of
interconnection obligations under the Telecommunications Act of 1996. We would
be required to offer our services for resale at retail prices, provide number
portability if technically feasible, provide dialing parity to competing
providers and non-discriminatory access to telephone numbers, directory
assistance, operator services and directory listings, provide access to poles,
ducts, conduits and rights-of-way and establish reciprocal compensation
arrangements for the transport and termination of telecommunications. Although
competitive local exchange carrier interstate access charges are generally
regulated as non-dominant carrier offerings and subject to minimal burdens, the
Federal Communications Commission recently adopted a Notice of Proposed
Rulemaking that asks whether it should regulate the terminating access charges
of such providers.

    The Federal Communications Commission determined that Internet traffic is
interstate in nature, not local, and has initiated a proceeding to determine
appropriate carrier-to-carrier compensation. At the same time, the Federal
Communications Commission declined to overturn a multitude of state decisions
requiring incumbent local exchange carriers to pay competitive local exchange
carriers compensation for delivering Internet traffic to Internet service
providers. To the extent we are treated as a competitive local exchange carrier,
this ruling would adversely affect the revenues that we might expect to receive
from the carriage of Internet service provider-bound traffic.

    INTERNATIONAL FACILITIES

    We are required to obtain regulatory approval to construct and operate
facilities used to provide international telecommunications services. If any of
our services are treated as international telecommunications services, we may be
required to obtain regulatory approvals and file tariffs to offer these
international services. Although these facilities authorizations and tariffs are
regulated on a streamlined basis subject to minimal regulation, there is a risk
that the Federal Communications Commission may deny or place burdensome
conditions on authorizations and tariff filings.

    OTHER FEDERAL COMMUNICATIONS REGULATIONS


    With limited exceptions, the current policy of the Federal Communications
Commission prohibits incumbent local exchange carriers from lowering prices to
certain customers without also lowering charges for the same service to all
similarly situated customers in the same geographic area. The Federal
Communications Commission, however, modified this constraint on incumbent local
exchange carriers who have specified levels of competition from competing local
exchange service providers and permit them to offer special rate packages to
certain customers, as it has done in a few cases, and permit other forms of rate
flexibility. The rules contemplate an increasing level of flexibility on a
city-by-city basis as competitors have facilities in place to compete for local
exchange services in those markets. Once such facilities attain 50% coverage the
rules contemplate only minimal regulation of carrier access offerings. This
added flexibility could have a material adverse effect on our ability to compete
in providing facilities or services that compete with incumbent local exchange
carriers interstate access services.


    The Telecommunications Act of 1996 currently requires Regional Bell
Operating Companies to obtain Federal Communications Commission authorization
prior to providing inter-local area and transport area telecommunications. Bell
Atlantic received such authorization for New York in December 1999. It is
anticipated that additional Regional Bell Operating Companies may receive
authorization in some states to provide telecommunications during 2000. Such
authority, if granted,

                                       24
<PAGE>
could increase competition from Regional Bell Operating Companies in providing
fiber and fiber services, which could adversely affect our business operations.

    The Federal Communications Commission has the responsibility under the
Telecommunications Act of 1996 to determine what elements of an incumbent local
exchange carrier's network must be provided to competitors on an unbundled
basis. In August 1999, the Federal Communications Commission required dark fiber
to be offered as an unbundled element. In addition, the Federal Communications
Commission had previously allowed state commissions to establish additional
unbundling requirements, and some states have required that incumbent local
exchange carriers unbundle dark fiber. The decisions by the Federal
Communications Commission to require unbundling of incumbent local exchange
carriers' dark fiber could increase the supply of dark fiber and decrease the
demand for our dark fiber and thereby have an adverse effect on the results of
our operations.


    The Federal Communications Commission recently instituted a proceeding that
could impose obligations on telecommunication carriers' obligation to provide
access to competitors or customers to their wiring located in multi-tenant
residential and business buildings. It is unknown at this time how the Federal
Communications Commission will rule in this proceeding so it is impossible to
evaluate its impact on our operations.


    STATE REGULATION

    Each state in the United States, as well as the District of Columbia and
U.S. territories, which are treated as states for the purpose of regulation of
telecommunications services, has its own laws for regulating providers of some
telecommunications-related services as "common carriers," as "public utilities,"
or under similar rubrics. We believe that the sale or lease of dark fiber
facilities is not subject to this type of regulation in most jurisdictions in
which we plan to construct facilities. However, our offering of transmission
services, as distinct from dark fiber capacity, likely will be subject to
regulation in each of these jurisdictions to the extent that these services are
offered for intrastate use, and the regulation may have an adverse effect on the
results of our operations.

    LOCAL REGULATION

    In addition to federal and state laws, local governments exercise legal
authority that may affect our business. For example, some local governments
retain the ability to license public rights-of-way, subject to the federal
limitation that local authorities may not prohibit entities from entering
telecommunications markets. Compliance with local requirements may delay entry
and increase our costs of doing business.

    CANADA

    REGULATION UNDER THE TELECOMMUNICATIONS ACT (CANADA)


    REGULATION OF RESELLERS



    We offer network services to our customers in Canada through resale
arrangements. Under these resale arrangements, we obtain the use of transmission
facilities on a contractual basis from Urbanlink and then offer bandwidth
services to our customers through the subsequent sale or lease, on a commercial
basis, of these contracted facilities. As a reseller, we are not generally
subject to the regulatory requirements of the Telecommunications Act (Canada).
However, there can be no assurance that the regulation of resellers in Canada
may not become more extensive in the future. In addition, while we believe that
our operations as a reseller in Canada fully comply with Canadian law, there can
be no assurance that a future determination of the Canadian Radio-television and
Telecommunications Commission or events beyond our control will not result in a
change in our status or affect our ability to offer services in Canada.


                                       25
<PAGE>

    RESTRICTIONS ON FOREIGN OWNERSHIP


    Under the Canadian ownership provisions of the Telecommunications Act, a
"telecommunications common carrier" is not eligible to operate in Canada unless
it is owned and controlled by Canadians. Furthermore, no more than 20% of the
members of the board of directors of a telecommunications common carrier may be
non-Canadians, and no more than 20% of the voting shares of a telecommunications
common carrier may be beneficially owned by non-Canadians. In addition, no more
than 33 1/3% of the voting shares of a non-operating parent corporation of a
telecommunications common carrier may be beneficially owned or controlled by
non-Canadians and neither the telecommunications common carrier nor its parent
may be otherwise controlled in fact by non-Canadians.


    Although we believe that our activities in Canada, including the Canadian
telecommunications arrangement, comply with the foreign ownership provisions of
the Telecommunications Act, there can be no assurance that a future Canadian
Radio-television and Telecommunications Commission determination or events
beyond our control will not result in our being required to comply with the
ownership provisions of the Telecommunications Act.



    On October 1, 1998, the Canadian Radio-television and Telecommunications
Commission issued Telecom Decision CRTC 98-17, which established a framework for
competition in Canada's international telecommunications services market to
coincide with the Government of Canada's decision to terminate the monopoly of
Teleglobe Canada Inc. over telecommunications facilities linking Canada to
overseas destinations. In that decision, the Canadian Radio-television and
Telecommunications Commission determined that a party acquiring an indefeasible
right of use interest in an international submarine cable would not necessarily
fall within the definition of a telecommunications common carrier. As a result,
acquirers of indefeasible rights of use in international submarine cables need
not be Canadian owned and controlled. However, given the fact that the Canadian
Radio-television and Telecommunications Commission's findings in Decision 98-17
were limited to indefeasible right of use interests held in international
submarine cables, as well as the fact that indefeasible right of use
arrangements can involve varying degrees of ownership and control over fiber
facilities, there can be no assurance that holders of indefeasible rights of use
acquired in domestic fiber facilities, including those obtained by us from
Urbanlink, would be exempt from the Canadian ownership provisions contained in
the Telecommunications Act.


    CONTRIBUTION

    The Canadian Radio-television and Telecommunications Commission is
considering reform of the current contribution regime. The Canadian
Radio-television and Telecommunications Commission's contribution regime was
originally established in 1992 as a means of ensuring that rates for local
residential telephone service remain affordable. Under the regime, providers of
certain types of long distance voice and data services are required to pay a
subsidy or "contribution" on each minute of traffic that is originated or
terminated on local switched telephone networks or on cross-border or overseas
access circuits. These contribution payments are pooled within each incumbent
local exchange carriers' territory and are paid out to incumbent local exchange
carriers and competitive local exchange carriers serving residential local
customers, based on the number of residential network access services they serve
and the level of the subsidy available in the rate band being served. On
March 1, 1999, the Canadian Radio-television and Telecommunications Commission
initiated a proceeding to consider possible reforms to the current contribution
mechanism. In the public notice that initiated the proceeding, the Canadian
Radio-television and Telecommunications Commission invited interested parties to
submit proposals on other mechanisms which could be used to collect
contribution. Although this public notice proceeding is not yet closed, some
parties in the proceeding have advocated that the current contribution regime be
converted to a revenue-based regime under which contribution would be

                                       26
<PAGE>
paid on a percentage of a telecommunications service provider's revenues
(regardless of the types of services offered by the service provider), rather
than on certain types of telecommunications traffic.


    We do not believe that the majority of our operations in Canada are subject
to any requirement to pay contributions under the current contribution regime.
However, given that the current contribution regime is under review by the
Canadian Radio-television and Telecommunications Commission, there can be no
assurance that we would be exempt from the requirement to pay contributions in
the future, particularly if the Canadian Radio-television and Telecommunications
Commission decides to adopt a revenue-based regime.



    EUROPE



    In Europe, in addition to those risk factors mentioned, there may be
additional regulatory or legal factors or changes which could adversely affect
our operations by increasing our costs or restricting the way in which we offer,
or our ability to offer, products, services or dark fiber capacity.



    Major delays in the construction and establishment of submarine cables could
occur due to delays in the granting of the environmental, planning and other
permissions relating to land which are required in order to land such cables.



    We may be refused other requisite rights of way, or there may be delays in
construction due to delays in the granting of such rights of way.



    Contrary to what is expected to be the case, in some or all European
countries, an individual telecommunications license or other telecommunications
authorization may be required in order for us to offer or control dark fiber,
and there may consequently either be a delay in carrying out the construction of
the projected dark fiber network, or, contrary to EC directive requirements,
national authorities in particular states of the EU may refuse to grant a
license for such activities.



    Concerning other planned services, including the offering of lit capacity
and other telecommunications services, individual Member States of the European
Union might refuse to grant a license, contrary to the requirement of EC
directives, or may subject the grant of a license or other authorization to
onerous conditions, including but not limited to investment requirements or
commitments, guarantees or bonds, which make the supply of the projected
services less profitable or not commercially viable.



    Regulatory intervention by the EC or Member State telecommunications or
antitrust authorities could reduce the price level of local, national or
international leased circuits/capacity to a level where it is less profitable or
not commercially viable for the projected activities to be undertaken in
specific countries or in the European Union.



    To the extent that we qualify in any individual Member State of the European
Union as an operator with a right to interconnect pursuant to the
EC Interconnection directive, we may be required to negotiate interconnection
with other operators with a right to interconnect in that Member State or
throughout the European Union.



    If we are required to obtain a license or authorization in any Member State
of the European Union then we may be obliged to pay license or authorization
fees which are high, or higher than anticipated, or we may be subject to
statistical reporting requirements or other regulatory burdens pursuant to such
licenses or authorizations.



    OTHER REGULATION



    We have, or upon consummation of our acquisition of GlobeNet will have,
operations based in Canada and the United States, Brazil, Venezuela and Bermuda
and anticipate operations in Europe


                                       27

and other foreign jurisdictions. We are exposed to risks inherent in
international operations, including the following:


    - general economic, social and political conditions;

    - the difficulty of enforcing agreements and collecting receivables through
      some foreign legal systems;


    - tax rates in some foreign countries may exceed those in Canada and foreign
      earnings may be subject to withholding requirements or the imposition of
      tariffs, exchange controls or other restrictions;


    - required compliance with a variety of foreign laws and regulations; and


    - changes in Canadian laws and regulations relating to foreign trade and
      investment.


CAPITAL MARKETS

CURRENCY EXCHANGE RATE FLUCTUATIONS COULD ADVERSELY AFFECT OUR FINANCIAL RESULTS

    Fluctuations in foreign currency exchange rates may affect our results of
operations and the value of our foreign assets, which in turn may adversely
affect reported earnings and the comparability of period-to-period results of
operations. Changes in currency exchange rates may affect the relative prices at
which we and foreign competitors sell products in the same market. In addition,
changes in the value of the relevant currencies may affect the cost of items
required in our operations.


OUR SUBORDINATE VOTING SHARES HAVE NEVER BEEN PUBLICLY TRADED AND THEIR PRICE
MAY BE VOLATILE



    Prior to the equity offering, you could not buy or sell our Subordinate
Voting Shares publicly. For a discussion of the factors the underwriters will
consider in determining the initial public offering price, see the section of
this prospectus entitled "Underwriting." Although an application will be made to
list our Subordinate Voting Shares on the Nasdaq National Market and The Toronto
Stock Exchange, an active public market for our shares might not develop or be
sustained after the equity offering. Moreover, even if such a market does
develop, the market price of our shares may decline below the initial public
offering price. The market price of our shares could be subject to significant
fluctuations due to a variety of factors, including actual or anticipated
fluctuations in our operating results and financial performance, announcements
of technological innovations by our existing or future competitors or changes in
financial estimates by securities analysts.


    Historically, the market price for securities of emerging companies in the
communications industry have been highly volatile. In addition, the stock market
has experienced volatility that has affected the market prices of equity
securities of many companies and that often has been unrelated to the operating
performance of such companies. These broad market fluctuations may adversely
affect the market price of our shares. Furthermore, following periods of
volatility in the market price of a company's securities, stockholders of such a
company have often instituted securities class action litigation against the
company. Any such litigation against us could result in substantial costs and a
diversion of management's attention and resources, which could adversely affect
the conduct of our business.


FUTURE SALES OF STOCK MAY ADVERSELY AFFECT OUR SHARE PRICE



    The market price of our Subordinate Voting Shares could drop in response to
possible sales of a large number of shares in the market after the equity
offering or to the perception that such sales could occur. As a result, we may
be unable to raise additional capital through the sale of equity at prices
acceptable to us. Following the equity offering, we will have approximately
712,000,000 Subordinate Voting Shares outstanding, or approximately 719,000,000
shares outstanding if the


                                       28
<PAGE>

underwriters exercise their over-allotment option in full. Of these shares,
persons other than our "affiliates" (as this term is defined under the
Securities Act and which includes Ledcor Inc.) may freely transfer the shares
sold in the equity offering without restriction or further registration under
the Securities Act. We, Ledcor Inc., our executive officers, directors and
substantially all of our shareholders have agreed not to offer, sell, contract
to sell, pledge or grant any option to purchase or otherwise dispose of their
shares for the periods set forth herein under "Shares Eligible for Future Sale"
without the prior written consent of Goldman, Sachs & Co., Donaldson, Lufkin &
Jenrette Securities Corporation and us, subject to limited exceptions. Sales of
Subordinate Voting Shares at the termination of this period, or the anticipation
of such sales could adversely affect the market price for the Subordinate Voting
Shares. See the section of this prospectus entitled "Shares Eligible for Future
Sale" for more information.



    We have entered into registration rights agreements with Mi-Tech
Communications, LLC, Canadian National Railway Company, the investors in our
private placement of redeemable convertible preferred shares, a consultant, our
strategic investors and certain of our executive officers which in each case
enables them to require us to register their shares and to include those shares
in registrations of shares made by us in the future. We currently have no plan
to file a registration statement for the sale of Subordinate Voting Shares held
by any of these parties. All of the investors have agreed not to dispose of or
hedge any shares for 12 months. We are contractually obligated to file one or
more registration statements in the future on demand. See the section of this
prospectus entitled "Share Capital Reorganization and Description of Capital
Stock--Registration Rights" for more information.



A THIRD PARTY MAY BE DETERRED FROM ACQUIRING US



    Our restated articles of incorporation include provisions that could delay,
deter or prevent a future takeover or change in control of us. These provisions
include the disproportionate voting rights of the Multiple Voting Shares
(relative to the Subordinate Voting Shares) to elect the members of our board of
directors and the authorization of our board to issue, without stockholder
approval, one or more series of Preferred Shares. These provisions may have the
effect of discouraging a third party from making a tender offer or otherwise
attempting to obtain control of us, even though such a change in ownership would
be economically beneficial to us and our stockholders. See the section of this
prospectus entitled "Share Capital Reorganization and Description of Capital
Stock" for more information.


WE DO NOT ANTICIPATE PAYING CASH DIVIDENDS

    We intend to retain future earnings, if any, to finance the operation and
expansion of our business and do not anticipate paying any cash dividends in the
foreseeable future. Our ability to pay dividends is limited by our debt
instruments. See the section of this prospectus entitled "Dividend Policy" for
more information.


INVESTORS WHO PURCHASE SUBORDINATE VOTING SHARES IN THE OFFERING WILL EXPERIENCE
IMMEDIATE AND SUBSTANTIAL DILUTION



    If you purchase our Subordinate Voting Shares in the offering, you will
experience immediate and significant dilution in the tangible book value of the
shares you purchase. This means that the price you pay will be significantly
greater than the net tangible book value of the shares you acquire. This
dilution is due to the fact that the effective cash cost to our existing
shareholders of the shares they have purchased in the past is significantly less
than the price at which our shares are being offered to the public in the
offering. See "Dilution."


                                       29
<PAGE>
                                USE OF PROCEEDS


    The estimated net proceeds from the sale of our Subordinate Voting Shares
are expected to be $718 million, net of underwriting discounts and other costs
and expenses payable by us. We expect our aggregate net proceeds from the
concurrent debt offerings to be $974 million. The closings of the Subordinate
Voting Shares offering and the debt offerings are not contingent on each other.



    We expect to use the net proceeds from the offerings and funds from
operations primarily:



    - to further develop and light our network;



    - to develop new facilities to enable us to provide value added network
      services such as colocation facilities and other communications services
      and products;



    - for future investments, acquisitions or strategic alliances in businesses
      or assets that are related or complementary to our existing business.
      However, we cannot assure you that we will successfully complete nor are
      we presently committed to make any such investments, acquisitions or
      strategic alliances; and



    - to fund operating losses, for working capital and for general corporate
      purposes.



    Following the consummation of our acquisition of GlobeNet, that company will
have an obligation to offer to purchase any and all of its $300 million
outstanding principal amount of senior notes. To the extent holders of the
senior notes accept that offer, some of the net proceeds may be used to purchase
those senior notes.


    We currently intend to allocate substantial proceeds to each of the
foregoing uses. However, the precise allocation of funds among these uses will
depend on future commercial, technological, regulatory and other developments
which may affect our business, the competitive climate in which we operate and
the emergence of future opportunities. Because of the number and variability of
factors that determine our use of the net proceeds of this offering, we cannot
assure you that our application of the net proceeds will not vary substantially
from our current intentions. Pending these uses, we intend to invest the net
proceeds of this offering in short-term U.S. investment grade and government
securities.


    Our 360ATLANTIC project, which has an estimated total cost of $865 million,
will be paid for with borrowings under our $565 million credit facility and
$300 million raised from private equity investors in September 1999. The
360ATLANTIC credit facility has been provided to a group of our subsidiaries and
is non-recourse to us.



    We anticipate that GlobeNet's 360AMERICAS project, which has an estimated
total cost of approximately $900 million, will be paid for with borrowings under
GlobeNet's $400 million credit facility, the proceeds of GlobeNet's
$300 million issuance of senior notes in July 1999 and GlobeNet's cash on hand.


    For more information about our anticipated funding sources and our uses of
these funds, see the section of this prospectus entitled "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."

<PAGE>
                                DIVIDEND POLICY

    We have never declared or paid any cash dividends on our shares. We intend
to retain any future earnings to support operations and to finance the growth
and development of our business and do not anticipate paying cash dividends on
our shares for the foreseeable future. In addition, the instruments governing
our debt restrict the payment of cash dividends on our shares.

                        DESCRIPTION OF OUR CAPITAL STOCK


    Concurrent with the closing of the offering, we will reorganize our share
capital so that it will consist of the following classes of shares:



    - Subordinate Voting Shares;



    - Multiple Voting Shares; and


    - Preferred Shares, issuable in series.


    We will be authorized to issue 500 billion shares of each of the foregoing
classes. On the closing of the offering, we will have 712,150,465 Subordinate
Voting Shares issued and outstanding, 81,840,000 Multiple Voting Shares issued
and outstanding and no Preferred Shares issued and outstanding.



    Our Subordinate Voting Shares and Multiple Voting Shares will be identical
except that:



    - each Subordinate Voting Share entitles the holder to one vote and each
      Multiple Voting Share entitles the holder to ten votes; and



    - each Multiple Voting Share is convertible at the option of the holder into
      one Subordinate Voting Share.



    We have appointed HSBC Bank USA and Montreal Trust Company of Canada as the
registrars and transfer agents for the Subordinate Voting Shares. For a
description of our share capital reorganization which will occur immediately
prior to closing and a more detailed description of the rights and attributes of
our capital stock, see "Share Capital Reorganization and Description of Capital
Stock."

                                    DILUTION



    As of December 31, 1999, our consolidated net tangible book value was
$357,489,000, or $0.53 per share. "Consolidated net tangible book value per
share" represents the total amount of our consolidated tangible assets, reduced
by the amount of total consolidated liabilities and divided by the number of
shares outstanding. Tangible assets are defined as our consolidated assets,
excluding intangible assets such as deferred financing costs. After giving
effect to the acquisition of GlobeNet, the acquisition of the minority interests
in certain of our subsidiaries, the issuance of additional shares derived from
the anti-dilution provisions afforded to certain shareholders and the equity
offering, after deducting underwriting discounts and commissions and estimated
expenses, our net consolidated tangible book value at December 31, 1999 would
have been $1,251,494,000 or $1.58 per share. This represents an immediate
increase in consolidated net tangible book value of approximately $1.05 per
share to the existing shareholders and an immediate dilution of $15.42 per share
to new investors in the equity offering.



    Dilution per share represents the difference between the price per share to
be paid by new investors and the net consolidated tangible book value per share
immediately after the equity offering. The following table illustrates the per
share dilution as of December 31, 1999.

    Our consolidated financial statements, the divisional financial statements
of the predecessor division and the consolidated financial statements of
GlobeNet have been prepared in accordance with U.S. GAAP. The results of
operations for the predecessor division are not comparable to our results of
operations after the telecommunications division of Ledcor was reorganized.



    EBITDA presented in the following table consists of net income (loss) before
interest expense, net of interest income, provision for income taxes,
depreciation, stock-based compensation,


                                       34

amortization of goodwill and income attributable to minority interest. EBITDA is
presented because we believe that it is a useful indicator of our ability to
meet debt service and capital expenditure requirements. It is not intended as an
alternative measure of operating results or cash flow from operations (as
determined in accordance with generally acceptable accounting principles).
EBITDA is not necessarily comparable to similarly titled measures for other
companies and does not necessarily represent amounts of funds available for
management's discretionary use.



    For purposes of calculating the ratio of earnings to fixed charges, earnings
consists of earnings (loss) before equity income, provision for income taxes,
income attributable to minority interest, amortization of goodwill and fixed
charges. Fixed charges consists of interest expensed and capitalized, the
portion of rental expense which we believe to be representative of interest
(assumed to be one-third of rental expense) and pre-tax earnings required to
cover the accretion on the redeemable convertible preferred shares. Pro forma
loss for the year ended December 31, 1999 would have been insufficient to cover
fixed charges by approximately $171 million.



    Capital expenditures represent actual cash expenditures incurred during the
period and do not include acquisitions of assets for non-cash consideration.
Route miles represent the number of miles spanned by fiber optic cable owned by
us or in respect of which we have acquired capacity pursuant to swaps, leases,
IRUs or other contractual rights at the end of the period, calculated without
including physically overlapping segments of cable.


    The following table presents selected consolidated financial data derived
from our consolidated financial statements. You should read the following

Condition and Results of Operations" and the financial statements and the

(1) To compute basic and fully diluted loss per share, net income of $23,640,000
    is reduced by a stock dividend of $5,000,000, accretion on preferred shares
    of $6,465,000 and an amount of $22,070,000 which represents the fair value
    of the Series A Non-Voting Preferred Shares issued to the existing
    shareholders for no consideration as a result of anti-dilution provisions in
    the original subscription agreement, resulting in a net loss to holders of
    Subordinate Voting Shares and Multiple Voting Shares of $9,895,000.

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

    The following should be read along with our Consolidated Financial
Statements and the Divisional Financial Statements of the telecommunications
division of Ledcor Industries, including the related notes, included elsewhere
in this prospectus.


GENERAL



    We were incorporated on February 5, 1998, but did not commence operations
until May 31, 1998. As of May 31, 1998 we entered into a series of agreements,
which we refer to as the reorganization, whereby Ledcor transferred to us the
construction equipment, some fiber optic strands and some other assets of Ledcor
Industries' telecommunications division. On September 27, 1999, we acquired
additional fiber optic network assets from Ledcor. Recently, we entered into a
series of agreements to transfer to Urbanlink certain Canadian
telecommunications facilities. We own 51% of the participating equity shares and
33 1/3% of the voting shares of Urbanlink. Because these transactions were
between entities under common control, the assets have been reflected in our
financial statements using the carrying amounts recorded in Ledcor's accounts.
We believe that the fair market values of the fiber assets we received and our
equity investment in Urbanlink are significantly greater than their carrying
amounts.



    We entered into two construction services agreements in which we agreed to
fulfill Ledcor's fiber optic network construction commitments concerning some
builds across Canada and the northern United States. In return, Ledcor paid us
an amount equal to 115% of our costs. Our obligations under these agreements
were substantially performed by January 1999. We also entered into a management
services agreement and two employee services agreements with Ledcor. See
"Relationships and Related Party Transactions--Transactions with
Ledcor--Description of reorganization and related agreements."



    Prior to the reorganization, we were a shell company created for the purpose
of continuing the business of Ledcor Industries' telecommunications division and
did not have any operations or material assets. Accordingly, two sets of
financial information are included in this prospectus. The Divisional Financial
Statements of Ledcor Industries' telecommunications division prior to May 31,
1998 reflect the operations of our predecessor as a contractor and network
developer. Our Consolidated Financial Statements for the period from the date of
incorporation through December 31, 1998 primarily reflect our operating results
due to the construction services agreements. Since January 1, 1999, the impact
of the construction services agreements has not been significant on our
consolidated financial statements.



REVENUES AND COSTS



    Since December 31, 1998 our revenues have been primarily generated from the
sale, lease or grant of indefeasible right of use ("IRU") of network
infrastructure. We anticipate a significant amount of our future revenues will
be derived from providing network services, including optical channels, private
line transmission, virtual voice trunking and packet-based data services
including Internet protocol ("IP") transport and Asynchronous Transfer Mode
("ATM"). We anticipate that, as we proceed with the development of our network,
the percentage of revenues which we receive from network services will increase
as a percentage of our total revenue and that by 2001 our network services will
provide our largest percentage of revenue on a consolidated basis and be a
significant source of income.



    Sales of network infrastructure include agreements in the form of
construction contracts and co-developments.


                                       38
<PAGE>

    Revenues from construction contracts to develop fiber optic systems are
calculated on the percentage of completion basis using the cost-to-cost method
over the life of the build. This method is used because we consider costs
incurred to be the best available measure of progress of these contracts. We
make provisions for all potential losses as soon as they become evident. We
recognize revenue for co-development agreements on a percentage of completion
basis.


    Following completion of a build, our retained fiber or conduit may be sold,
granted through an IRU or leased to a third party. Lease revenues are recognized
as earned over the life of the lease.

    In June 1999, the Financial Accounting Standards Board issued Interpretation
No. 43, "Real Estate Sales, an interpretation of FASB Statement No. 66." The
interpretation is effective for sales of real estate with property improvements
or integral equipment entered into after June 30, 1999. Under this
interpretation, title must transfer to a lessee in order for a lease transaction
to be accounted for as a sales-type lease.


    All future sales and grants of IRUs of dark fiber or capacity will be
evaluated under the new interpretation. If we do not pass title on the integral
equipment pursuant to the agreements related to future transactions involving
dark fiber or capacity sales and/or IRUs, or if such transactions otherwise do
not meet the criteria in FASB statement No. 66, we will recognize the transfer
prices as revenue ratably over the terms of the applicable agreements, rather
than when the applicable segments of our network are delivered to, and accepted
by, the purchaser. Usually, the purchaser pays the entire cash price to us upon
its acceptance. Therefore, although the application of the new interpretation
may affect the times of recognition of revenue from dark fiber and capacity
sales, we expect there will be no effect on our financial position or cash flows
from this prospective change in accounting.


    Cost of sales of network infrastructure, particularly dark fiber and
conduit, consist of direct costs such as the conduit, fiber optic cable,
construction of regeneration facilities, sales and commissions and labor and an
allocation of indirect costs such as rights-of-way ("ROW") environmental
restoration, equipment costs, insurance and interest charges. Costs of sales of
network services include only the direct costs of sales commissions and
points-of-presence ("POP") space. Indirect costs of network services are
included in general and administrative expenses and depreciation.

ELIMINATION OF MINORITY INTERESTS


    We have recently acquired the minority interest in each of WFI-CN
Fibre Inc. ("360-CN") and Worldwide Fiber IC Holdings Inc. ("IC Holdings") in a
cash and share exchange transaction, as a result of which CN will acquire
approximately 9,411,765 Subordinate Voting Shares. In addition, we have acquired
the remaining 25% minority interest in Worldwide Fiber (USA) Inc. ("360-USA")
from Mi-Tech Communications, LLC ("Michels") in exchange for approximately
18,352,941 Subordinate Voting Shares.


RESULTS OF OPERATIONS


360NETWORKS INC.
  YEAR ENDED DECEMBER 31, 1999 AND PERIOD FROM FEBRUARY 5, 1998 TO DECEMBER 31,
  1998 (OPERATIONS COMMENCED MAY 31, 1998)



    REVENUE for the year ended December 31, 1999 was $359,746,000, versus
$164,319,000 for the period from May 31, 1998 (commencement of operations) to
December 31, 1998. Revenue in the current year was primarily derived from sales
of conduit and fiber optic strands along segments in the Pacific Northwest,
Northeast U.S. and eastern Canada. Revenues in the seven month period


                                       39
<PAGE>

ended December 31, 1998 were primarily derived from the Construction Services
Agreements with Ledcor.



    COSTS were $250,612,000 (70% of revenue) for the year ended December 31,
1999, versus $147,621,000 (90% of revenue) for the period from May 31, 1998
(commencement of operations) to December 31, 1998.



    GROSS PROFIT for the year ended December 31, 1999 was $109,134,000 (30% of
revenue), versus $16,698,000 (10% of revenue) for the period from May 31, 1998
(commencement of operations) to December 31, 1998. The improvement in gross
margin reflects our evolution from network construction to ownership and
development of network infrastructure and services.



    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES were $21,846,000 (6% of
revenue) for the year ended December 31, 1999, versus $2,274,000 (1% of revenue)
for the period from May 31, 1998 (commencement of operations) to December 31,
1998. In the current year we completed a majority of the tasks necessary to
perform the transition from Ledcor's management information and accounting
systems to our own. General and administrative expenses are expected to continue
to increase as we develop our systems, hire additional personnel and implement
our marketing and sales strategy.



    STOCK-BASED COMPENSATION EXPENSE for the year ended December 31, 1999 was
$7,116,000 relating to stock options granted during the year. Additionally,
$188,553,000 of deferred compensation will be amortized over the remaining
vesting term of the stock options.



    INTEREST EXPENSE was $33,908,000 for the year ended December 31, 1999 and
was principally due to the issue of senior notes in December 1998 and
July 1999. Interest income totaled $18,122,000 and arose from the investment of
the proceeds of the senior notes in short-term, investment grade securities.
Interest expense and interest income for the period from May 31, 1998
(commencement of operations) to December 31, 1998 was $492,000 and $267,000,
respectively.



    INCOME TAXES provided for the year ended December 31, 1999 totaled
$30,314,000, versus $5,643,000 for the period from May 31, 1998 (commencement of
operations) to December 31, 1998. These consist primarily of current taxes
arising from our U.S. and Canadian operations.



    MINORITY INTEREST for the year ended December 31, 1999 totaled $7,434,000
and represents 25% of the net income of 360-USA, 360-CN and IC Holdings.


TELECOMMUNICATIONS DIVISION--LEDCOR INDUSTRIES
  NINE MONTHS ENDED MAY 31, 1998


    REVENUES GENERATED FROM CONTRACTS for the nine months ended May 31, 1998
were $54,633,888. The revenues for this period were principally derived from
development for Ledcor Industries.



    CONTRACT COSTS were $45,321,566 for the nine months ended May 31, 1998.
Contract costs primarily represent the costs associated with engineering,
designing, building and managing third-party construction contracts. Contract
costs as a percentage of revenue for the nine months ended May 31, 1998 were
83%.



    GENERAL AND ADMINISTRATIVE EXPENSES for the nine months ended May 31, 1998
were $710,240, representing 1% of revenues for the period. General and
administrative expenses for the nine month period ended May 31, 1998 are
primarily derived from overhead to accommodate progress on construction projects
for Ledcor Industries and management of builds for third parties.


    INCOME TAX EXPENSE (RECOVERY) for the nine months ended May 31, 1998
represents a current expense of $5,509,000 and a recovery, on a deferred basis,
of $1,600,000 using an effective tax rate

                                       40
<PAGE>
of 45%. As a division, we would not in fact report taxes, but would have been
consolidated within the tax return filed by Ledcor Industries. The difference
between current tax expense and deferred tax recovery is due to temporary
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases.

TELECOMMUNICATIONS DIVISION--LEDCOR INDUSTRIES
  YEAR ENDED AUGUST 31, 1997


    REVENUES GENERATED FROM CONTRACTS for the year ended August 31, 1997 were
$58,007,652. The revenues for this period are principally derived from the
commencement of building assets for Ledcor Industries and management of the
Alaska Fiber Star build in Alaska.



    CONTRACT COSTS were $49,184,985 for the year ended August 31, 1997. Contract
costs for this period are primarily derived from the costs associated with the
engineering, design and building of a construction project for Ledcor Industries
and management of the Alaska Fiber Star build in Alaska. Contract costs as a
percentage of revenue for the year ended August 31, 1997 were 85%. Contract
revenues and contract costs for the year ended August 31, 1997 increased
significantly due to the business in which Ledcor Industries had entered into,
which was the building of a construction project and selling of its components
to third parties. This was a different business than the business previously
conducted by the telecommunications division in which Ledcor Industries would
construct and develop fiber optic systems on a contract basis for specific
telecommunications clients. Since this was a new business for Ledcor Industries
the gross margin compared to prior years is not comparable.



    GENERAL AND ADMINISTRATIVE EXPENSES for the year ended August 31, 1997 were
$863,373, representing 2% of revenues for the period. The general and
administrative expenses for this period are primarily comprised of the overhead
necessary to accommodate the commencement of the Ledcor Industries project and
management of the Alaska Fiber Star build in Alaska.


    INCOME TAX EXPENSE for the year ended August 31, 1997 represents a current
expense of $338,000 and a deferred expense of $3,282,000 using an effective tax
rate of 45%. As a division, we would have been included within the tax return
filed by Ledcor Industries. The difference between current tax expense and
deferred tax expense is due to temporary differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases.


LIQUIDITY AND CAPITAL RESOURCES



    We have an aggressive business plan to build out our network. By the end of
2001, our planned network will consist of approximately 56,300 route miles in
North America, Europe and South America including an undersea cable between
North America and Europe and an undersea cable between South America and North
America. We intend to expand our network including network services to provide
connectivity on a global basis. We offer network services to meet our customers'
demands, enable Internet services and intend to develop products and services
that capitalize on the convergence of telecommunications and high-bandwidth
applications and services. Building out the network will require a significant
investment in the development of fiber and conduits held for sale, grant of IRU,
or lease and the purchase of additional network infrastructure and equipment to
establish transmission facilities.



    We estimate that the total cost to develop and light our network is
approximately $4.8 billion.



    - We estimate that the total cost to complete and light our network of
      24,100 route miles in North America will be $1.7 billion.



    - We estimate that the total cost to complete and light our network of
      10,600 route miles in Europe will be $360 million.


                                       41
<PAGE>

    - We estimate that the total cost of the 360ATLANTIC undersea cable project
      to be approximately $865 million. The majority of these costs are subject
      to fixed price contracts.



    - We estimate that the total cost of the 360AMERICAS undersea cable project
      to be approximately $900 million. The majority of these costs are subject
      to fixed price contracts.



    - We estimate that the total cost to acquire and develop existing and future
      colocation facilities in North America and Europe to be approximately
      $860 million.



    In order to finance the above costs of network development:



    - For North America, we have issued $675 million of senior notes and we plan
      to use some of the proceeds of this offering and concurrent debt offerings
      and cash from operations.



    - For Europe, we plan to use some of the proceeds of this offering,
      concurrent debt offerings and cash from operations.



    - For our 360ATLANTIC undersea cable project, we used a significant portion
      of the proceeds from our sale of our $345 million of redeemable
      convertible preferred shares in September 1999 and have also entered into
      a $565 million credit facility dedicated to the 360ATLANTIC undersea cable
      project, of which $100 million has been drawn. The 360ATLANTIC credit
      facility has been provided to a group of our subsidiaries and is
      non-recourse to us.



    - For our 360AMERICAS undersea cable project, we plan to issue Subordinate
      Voting Shares to acquire all of the outstanding shares of GlobeNet. We
      also plan to use the proceeds of GlobeNet's $300 million senior notes and
      GlobeNet's $400 million credit facility, of which $100 million has been
      drawn. The 360AMERICAS credit facility will be non-recourse to us. We are
      required to use GlobeNet's cash to fund the completion of this project.



    - For acquisition of the colocation facilities in North America and Europe
      that we have agreed, subject to execution of definitive agreements, to
      acquire, we plan to issue equity and use up to $250 million of our
      existing cash balances. We expect to use some of the proceeds of this
      offering and the concurrent debt offerings and cash from operations to
      further develop these facilities and to acquire and develop additional
      colocation facilities in North America and Europe.



    Our estimated capital expenditures for our current network development plans
for the year ending December 31, 2000 are $2.8 billion, of which approximately
$1.2 billion will be used for our terrestrial network in North America and
Europe, approximately $500 million will be used for 360ATLANTIC, approximately
$730 million will be used for 360AMERICAS and approximately $400 million will be
used for the acquisition and development of colocation facilities. We anticipate
that these funding sources will provide us with sufficient capital to complete
our terrestrial and undersea networks and to implement our related network
services strategy. However, because the cost of developing our network and
implementing our network services strategy will depend on a variety of factors,
many of which are beyond our control, including changes in the competitive
environment of our current and planned markets, we expect that our actual costs
may vary materially from those currently budgeted. In the event that our actual
costs exceed our current budget or we do not have the funds we anticipate, we
have the ability to adjust the number or sequence of segments we develop. We
anticipate that we will continue to experience negative cash flow (after capital
expenditures) as we build out the network which is expected to be completed by
the end of 2001.


                                       42
<PAGE>

    In addition to our planned network, we expect to pursue opportunities to
expand geographically or enhance the services that we offer our customers. We
will also seek to identify opportunities to develop new facilities which enable
us to provide value added network services such as colocation services and other
communications services and products. Accordingly, from time to time we may seek
to raise additional capital in the debt and/or equity capital markets prior to
completion of our planned network. We cannot assure you that we will be
successful in raising the capital necessary for completion of the remainder of
our planned network development, the implementation of our network services
strategy, the 360ATLANTIC and 360AMERICAS projects or for other opportunities on
a timely basis or on terms that are acceptable to us.



    We currently intend to offer $1.0 billion of senior notes in the concurrent
debt offerings. We may increase the aggregate amount of senior notes sold in
such offerings. Any such increase would increase our cash and cash equivalents
but would also increase our interest expense.



    At December 31, 1999, we had working capital of $655 million, including
$521 million in cash or cash equivalents. Cash used in operations during the
year ended December 31, 1999 totaled $97 million.



    We cannot assure you that our cash flow and capital resources will be
sufficient to repay the notes and any other debt we may incur in the future, or
that we will be successful in obtaining alternative financing. If we are unable
to repay our debts, we may be forced to reduce or delay the completion or
expansion of our network, sell some of our assets, obtain additional equity
capital or refinance or restructure our debt. If we are unable to meet our debt
service obligations or comply with our covenants, a default under our debt
agreements would result. To avoid a default, we might need waivers from third
parties, which might not be granted. See "Risk Factors--Leverage."


ACCOUNTING PRONOUNCEMENTS

    We adopted the American Institute of Certified Public Accountants' Statement
of Position 98-5, "Reporting on the Costs of Start-Up Activities" (SOP 98-5)
effective January 1, 1999. SOP 98-5 requires that all start-up costs be expensed
and that the effect of adopting SOP 98-5 be reported as the cumulative effect of
a change in accounting principle. The effect of adopting SOP 98-5 on our results
of operations was immaterial.


    We adopted the American Institute of Certified Public Accountants' Statement
of Position 98-1, ("SOP98-1"), "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use" effective January 1, 1999 which requires
that costs incurred for the development of internal use software be recorded as
an asset and amortized over its useful life. The effect of adopting SOP 98-1 on
our operations is not material.


    We adopted Statement of Financial Accounting Standards (SFAS) No. 131,
"Disclosures about Segments of an Enterprise and Related Information," during
the fourth quarter of 1998. SFAS No. 131 established standards for reporting
information about operating segments and related disclosures about products and
services, geographic areas and major customers.

    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." This statement
established accounting and reporting standards for derivative instruments,
including some derivative instruments embedded in other contracts and for
hedging activities. We do not expect the adoption of SFAS No. 133 to have a
material impact on our consolidated financial statements.

    In June 1999, the Financial Accounting Standards Boards (FASB) issued
Interpretation No. 43, "Real Estate Sales, an interpretation of FASB Statement
No. 66." The interpretation is effective for sales of real estate with property
improvements or integral equipment entered into after June 30, 1999. Under this
interpretation, title must transfer to a lessee in order for a lease transaction
to be

                                       43
<PAGE>
accounted for as a sales-type lease. After June 30, 1999, the effective date of
FASB Interpretation No. 43, sales-type lease accounting will only be appropriate
for dark fiber and capacity leases where title under the lease is transferred to
the lessee or if the agreement was entered into after June 30, 1999.
Transactions will be accounted for as operating leases where title is not
transferred to the lessee.

MARKET RISK DISCLOSURES

    INTEREST RATE RISK

    We have interest rate risk exposure related to our senior notes, which have
a fixed interest rate. The notes will be subject to interest rate risk resulting
from a future decrease in interest rates on obligations with comparable terms
below the interest rate on the senior notes. We currently do not mitigate the
risk of interest rate movements through the use of interest rate swaps or other
derivative instruments. However, subsequent to the offering we may choose to
manage our risk associated with interest rate movements through an appropriate
balance of fixed and variable rate obligations. To maintain an effective balance
of fixed and variable obligations, we may elect to enter into specific interest
rate swaps or other derivative instruments as we deem necessary. The senior
notes pay interest at fixed rates.

    The table below provides information about our senior notes.

have provisions which, in certain circumstances, permit or oblige us to redeem
all or part of the notes before their redemption dates.

    FOREIGN CURRENCY RISK

    We presently do not utilize derivative or other financial instruments to
hedge the risk associated with the movement in foreign currencies. However,
management continually monitors fluctuations in these currencies and will
consider the use of derivative financial instruments or employment of other
investment alternatives if cash flows or investment returns so warrant.

                                    BUSINESS


    We are a leading independent, facilities-based provider of fiber optic
communications network products and services. By the end of 2001, we expect our
network to consist of approximately 56,300 route miles in North America, Europe
and South America, including an undersea cable between North America and Europe
and an undersea cable between South America and North America. We recently
agreed, subject to execution of definitive agreements, to aquire colocation
facilities in 13 cities in North America and Europe comprising approximately
3.9 million square feet. We intend to expand our network to provide connectivity
on a global basis. Our network's design uses state-of-the-art optical
technologies that we believe greatly reduces complexity and cost while allowing
us to offer increased reliability and a wide range of products and services. In
addition, we offer network services to meet our customers' demands, enable
Internet services and intend to develop products and services that capitalize on
the convergence of telecommunications and high-bandwidth applications and
services. Our network is scheduled to be completed by the end of 2001.



    Our network consists of fiber optic assets and capacity that we have
installed or acquired from other developers and carriers through swaps,
purchases, leases, IRUs or other contractual rights along diverse ROW. In North
America, our network is expected to cover approximately 24,100 route miles, of
which more than 12,200 route miles have been developed to date, encompassing
both long-haul and intra-city route miles and providing connectivity among
approximately 50 major population centers. In Europe, our network is expected to
cover approximately 10,600 long-haul route miles (assuming, with respect to
1,300 route miles, the exercise of an option that we have), of which more than
4,900 route miles have been developed to date, providing connectivity among
approximately 35 major population centers. Our 7,600 route mile fully protected
undersea cable between North America and Europe will have the capacity to be a
1.92 terabits per second ("tbps"), self-healing ring that will connect landing
sites in Boston, Halifax, Dublin and Liverpool and to major gateway cities in
Europe and North America, including London and New York. Our planned 14,000
route mile fully protected undersea cable between South America and North
America will have the capacity to be a 1.28 terabits per second, self-healing
ring that will be able to offer city-to-city connectivity between 6 major
population centers in Brazil, Venezuela, Bermuda and Argentina and the United
States. We intend to expand our planned network to more population centers
through the addition of intercity and city ring capacity in North America,
Europe and South America. We are also reviewing opportunities to expand the
geographic reach of our network, including transpacific connectivity to Asia.



    We believe that there is growing demand for fiber optic capacity and related
network elements to transmit and service high-bandwidth data, voice and video.
This growing demand is being accelerated by new applications and services and by
improvements in "last mile" technology such as digital subscriber line ("DSL")
and cable modems. In this changing market environment, we believe that we are in
a favorable competitive position to satisfy this demand relative to other
service providers due to our low-cost, seamless technology and consistent
network operating architecture. We have achieved a low-cost position by:



    - leveraging our construction skills;



    - co-developing and swapping along some corridors of our network;



    - using equity as payment for important elements such as bulk rights-of-way;
      and



    - using optical design and technologies that eliminate layers of equipment
      traditionally required to support legacy systems.



    Our current and targeted customers include new and incumbent
telecommunications service providers ("TSPs"), Internet service providers
("ISPs"), application service providers ("ASPs"), storage service providers
("SSPs") and large organizations ("LORGs") with enterprise network needs. We
believe that these customers have a limited choice of independent service
providers


                                       45
<PAGE>

capable of offering high-capacity, reliable, secure and cost-effective services,
including enabling Internet services, between major population centers in North
America, Europe and South America. As a result, we believe that our targeted
customers will buy services from us rather than purchase them from another
source or build these service capabilities themselves. To meet our customers'
requirements, we offer a wide range of services on a scalable basis, including:



    - network services--optical channels, private line transmission,
      packet-based data services such as IP transport and ATM, and virtual voice
      trunking; and



    - network infrastructure--dark fiber and conduit for sale, grant of IRU or
      lease and construction services supporting the development of our network.



    Through the colocation facilities that we have agreed to acquire we will be
able to provide additional network services such as Internet data centers,
applications hosting, electronic commerce support and web hosting. We intend to
expand our business to include additional network services such as video
transport services, independent Internet access for transport and peering and
management services to allow carriers to migrate from circuit-switched
technologies to packet-based technologies.



    We expect to enable our customers to establish and maintain a strong
competitive position in providing services to their end users. We believe that
our independence, product design, seamless technology, consistent network
architecture, simple billing systems and end-to-end international connectivity
will enable us to gain a strong market position.



    We plan to realize the value of the network through developing a broad range
of managed bandwidth and Internet enabling products and services and the sale,
grant of IRU, lease or swap of dark fiber and conduit. We are adding the
necessary transmission equipment to enable us to provide bandwidth services and
other value-added network services to carriers and other service providers along
segments of our network. We intend to enhance the connectivity of the network
and satisfy customer demand through purchases, leases and swaps of bandwidth and
through joint ventures.


MARKET OPPORTUNITY

    Our network is designed to provide our customers with secure, independent
transmission facilities and sufficient capacity on a local, regional, national
or international basis to accommodate their increasing demand and plans for
expansion. According to The Yankee Group and other industry sources, growth in
the high-bandwidth telecommunications industry is expected to continue due to a
number of factors, which include:

    - INNOVATIONS AND ADVANCES IN TRANSMISSION TECHNOLOGY. Technological
      innovations continue to increase the capacity and speed of advanced fiber
      optic networks while decreasing the cost of transmission allowing for
      continued growth in Internet usage and increases in the number of network
      users. This increased capacity and speed has resulted in the development
      of bandwidth-intensive applications. Improvements in "last mile"
      technology, such as DSL, cable modems and fixed and 3G wireless access are
      contributing to the significant increase in the number of subscribers
      using such applications. In addition, the anticipated proliferation of
      wireless Internet and data technologies and devices such as 3G broadband
      technology are also expected to contribute to increases in demand for
      bandwidth.


    - INCREASING DEMAND FOR HIGH-BANDWIDTH APPLICATIONS, LARGELY DRIVEN BY THE
      INCREASE IN INTERNET TRAFFIC. There has been, and according to The Yankee
      Group there will continue to be a significant growth in demand for
      Internet, local loop data, video services and long distance. The increase
      in computer power and usage, as well as the continued demand for and
      development of faster Internet connection speeds, are driving significant
      increases in communications use for Internet and data services.


                                       46
<PAGE>
    - DEREGULATION OF THE TELECOMMUNICATIONS INDUSTRY, WHICH HAS RESULTED IN A
      PROLIFERATION OF SERVICE PROVIDERS. The telecommunications industry
      continues to experience liberalization on a global basis. Our
      high-bandwidth platform allows both new entrants to compete in this market
      and existing service providers to expand into new markets.

BUSINESS STRATEGY


    We believe that demand for high-bandwidth data transmission capacity from
TSPs, ISPs, ASPs, SSPs and LORGs with enterprise network needs will increase
substantially over the next several years. The key elements of our business
strategy to exploit the growing demand for bandwidth and enhanced network
services are to:



    PROVIDE HIGH-BANDWIDTH CONNECTIVITY BETWEEN, AND COLOCATION FACILITIES IN,
MAJOR GLOBAL POPULATION CENTERS.  The footprint of our network is designed with
the input of our customers and, when complete, our combination of terrestrial
and undersea fiber networks will allow us to offer our customers seamless and
scalable connectivity between major population centers in North America, Europe
and South America, areas in which bandwidth demand is high and is expected to
grow rapidly. We intend to expand our planned network to more population centers
through the addition of intercity and city ring capacity in North America,
Europe and South America. We are also reviewing opportunities to expand the
geographic reach of our network to have transpacific connectivity to Asia.



    DEVELOP AND OPERATE A TECHNOLOGICALLY ADVANCED, HIGH-CAPACITY, LOW-COST
NETWORK.  Our network is designed with the most advanced commercially available
technology to provide the highest levels of reliability, security and
flexibility demanded by our customers. Generally, construction to add to our
network is commenced only after we have pre-sold sufficient strands and conduit
to cover approximately 50% of our anticipated cost of that segment, thereby
reducing capital risk and creating a low-cost structure relative to our
competitors. In some segments we may seek a co-developer to fund a portion of
the project in exchange for receiving fiber or conduit assets. In appropriate
circumstances, the strategic nature of a segment may cause us to retain a higher
percentage of fiber and conduit, and associated costs, for our own account. We
believe that our network will have a low-cost basis relative to other
telecommunications carriers for the following reasons:



    - Sophisticated network architecture based on DWDM optics and packet
      switching reduces the complexity and the number of component systems that
      were previously required to deliver voice, Internet and data services.
      This simplified approach reduces our capital expenditures and operating
      expenses relating to billing support, program management and systems
      support.



    - The installation of multiple fibers per route mile and spare conduits
      reduces the per fiber mile cost to construct, operate and upgrade our
      network.


    - Some of our current ROW, licenses, permits and franchises are valuable
      assets that would be costly and difficult for others to procure or
      replicate in the future.


    - Where possible, our policy is to retain fiber assets for our own use along
      routes where we complete third-party construction.



    Our low-cost structure should allow us to remain price competitive with
other providers of broadband communications infrastructure and Internet
connectivity services while sustaining margins and providing customers a
cost-effective alternative to constructing their own networks.



    EXTEND THE REACH OF OUR NETWORK THROUGH DEVELOPMENT, SWAPS AND ACQUISITIONS
OF FIBER AND CAPACITY.  We plan to continue to develop our network to extend its
connectivity to major global population centers. For example, we have recently
entered into a joint build agreement with Telewest in the United Kingdom.
Further, we intend to continue to explore strategic opportunities


                                       47
<PAGE>

and the use of swaps of fiber and capacity to extend the reach of our network at
a low incremental cost. Our recent agreements with Telia to expand our network
footprint in Europe through a fiber swap and with GlobeNet to expand our
connectivity with South America through a cable acquisition are examples of this
strategy.



    EXPAND OUR MARKETING CAPABILITIES.  We are focused on providing our network
services to TSPs, ISPs, ASPs, SSPs and LORGs with enterprise network needs. In
North America, our customer relationships are cultivated and maintained by our
direct sales force and marketing staff. We intend to expand our European sales
and marketing efforts by hiring additional managers and salespeople in new
regional European sales offices by the end of the year.



    INCREASE, IN COLLABORATION WITH OUR CUSTOMERS, THE NUMBER OF PRODUCTS AND
SERVICES THAT WE OFFER, INCLUDING MANAGED BANDWIDTH AND INTERNET ENABLING
PRODUCTS AND SERVICES.  We offer our customers managed bandwidth and Internet
enabling products and services such as colocation facilities. We anticipate
offering services such as Internet data centers, applications hosting,
electronic commerce support and web hosting to meet our customers' evolving
needs and capitalize on the expanding demand for new telecommunications products
and services. We plan to develop an extensive range of innovative products and
services which will use our state-of-the-art IP-based network infrastructure.



    CAPITALIZE ON MANAGEMENT EXPERIENCE AND RELATIONSHIPS.  We have assembled
and will continue to build a strong management team and board of directors with
communications expertise and extensive experience in network design,
construction, operations and sales. Members of our board of directors and our
new Chief Executive Officer, Gregory Maffei, have extensive experience in
initiating, pursuing and implementing strategic alliances in communications and
technology industries. In addition, Michael Dell, Chairman and Chief Executive
Officer of Dell Computer Corporation, Terence Matthews, Chairman and Chief
Executive Officer of Newbridge Networks Corporation, Dr. Nathan Myhrvold, Chief
Technology Officer of Microsoft Corporation, Anthony Naughtin, President and
Chief Executive Officer of InterNAP Network Services Corporation, and Denis
O'Brien, Jr., Chairman of Esat Telecom Group, plc, each recently agreed to join
our Technology Advisory Board, which will advise us on network technology
directions, help us develop products and services to meet the requirements of
our customers and capitalize on the convergence of telecommunications and high
bandwidth applications and services.



    PURSUE ADDITIONAL STRATEGIC ALLIANCES IN NETWORK SERVICES AND
TECHNOLOGY.  We will pursue additional strategic alliances with communications
providers that have high-bandwidth needs and are willing to offer us long-term,
high capacity commitments for traffic on our network. Such strategic alliances
could also allow us to combine our capabilities with those of our strategic
alliance partners and thereby offer our customers additional products and
services. Our investment in TeraBeam Corporation, an emerging broadband services
provider, is an example of this strategy.


THE NETWORK


    Our network will cover approximately 56,300 route miles and will encompass
long-haul and intra-city routes and an undersea cable between North America and
Europe and an undersea cable between South America and North America. Our
network consists of fiber optic assets and capacity that we have installed or
acquired from other developers and carriers through swaps, purchases, leases,
IRUs or other contractual rights along diverse ROW. We intend to expand our
network including bandwidth and other Internet enhancing services to provide
connectivity on a global basis to meet our customers' demands and in response to
our needs for connectivity for our telecommunications business.


                                       48
<PAGE>
NORTH AMERICA


    In North America, our network is expected to cover approximately 24,100
route miles, encompassing both long-haul and intra-city route miles by the end
of 2001. We intend to further develop, swap, lease, obtain IRUs in respect of,
or purchase additional long-haul route miles and intra-city rings in North
America. The footprint will consist of the following:



    - a North American long-haul fiber optic network including: (1) three
      primary east-west routes and (2) three primary north-south routes, running
      along the West Coast, the Mississippi River Valley and the East Coast. Our
      network in North America will serve approximately 50 major population
      centers; and



    - a series of intra-city networks in Toronto, Vancouver, Montreal, Ottawa
      and Calgary, in addition to the city ring currently under construction in
      Seattle.



EUROPE



    In Europe, our network is currently expected to cover approximately 10,600
long-haul route miles (assuming, with respect to 1,300 route miles, the exercise
of an option that we have) providing connectivity among approximately 35 major
population centers by the end of 2001.



    The fiber we acquired via the KPNQwest, Telia, Telewest and Carrier1
transactions places our assets in ten European countries. The planned footprint
will consist of eight rings connecting the following cities:


    - Liverpool, Manchester, Birmingham, Bristol, London, Cambridge and
      Sheffield;

    - London, Paris, Strasbourg, Frankfurt, Dusseldorf, Hamburg and Amsterdam;

    - Hamburg, Kolding and Copenhagen;


    - Copenhagen, Stockholm and Oslo;



    - Frankfurt, Stuttgart, Munich, Dresden, Berlin, Hamburg and Cologne;



    - Stuttgart, Zurich, Milan, Torino, Marseilles, Lyon, Geneva, Basel and
      Kehl;



    - Paris, Lyon, Toulouse and Bordeaux; and



    - Lyon, Marseilles, Barcelona, Valencia, Bilbao, Bordeaux and Toulouse.


    These routes will be acquired through the following agreements:


    - KPNQWEST. In March 2000, we signed an agreement with KPNQwest Carrier
      Services B.V. ("KPNQwest"), under which we will purchase for a twenty-year
      period an IRU for approximately 4,500 route miles of multiple fiber
      strands on KPNQwest's Southern European network covering 25 population
      centers. The agreement contemplates that KPNQwest will deliver the fibers
      to us in segments and rings starting in the third quarter of 2000, with a
      final delivery date in the fourth quarter of 2001. In addition, KPNQwest
      will provide us with colocation and maintenance services. Also in March
      2000, we signed an agreement with KPNQwest Atlantic Limited under which
      KPNQwest Atlantic will purchase for a twenty-year period an IRU for
      capacity on our network between New York City and London. We will deliver
      this capacity over a two-year period starting in March 2001. Each of these
      two agreements is subject to due diligence and other conditions that
      entitle either party to terminate the agreements without penalty prior to
      May 1, 2000.



    - TELIA. In December 1999, we signed a contract with Telia under which we
      will swap for a twenty-year period an IRU for multiple fiber strands on
      part of our North American network in exchange for an IRU for
      approximately 4,000 route miles of multiple fiber strands of Telia's
      European network covering Germany, France, the United Kingdom, the
      Netherlands, Denmark, Sweden and Norway. The contract contemplates that we
      will deliver fibers to Telia by the end of the first quarter of 2001 and
      Telia will deliver the fibers to us by the end of the fourth quarter of
      2000. In addition, we will provide each other with colocation services,


                                       49
<PAGE>

      regeneration sites, points of presence in main cities and operations and
      maintenance services.



    - TELEWEST. In December 1999, we signed a co-development agreement with
      Telewest to provide us with multiple conduits on an approximate 780 route
      mile ring network which will connect Liverpool to London via Manchester,
      Birmingham and Bristol and via Sheffield and Cambridge. In addition, we
      have an option to require Telewest to provide access to existing dark
      fiber on two diverse routes connecting Liverpool to London on a backup
      network with common regeneration sites if the co-development assets are
      not delivered on schedule.



    - CARRIER1. In December 1999, we signed a contract with Carrier1 enabling us
      to order wholesale capacity on their network connecting London to 18 major
      population centers beginning March 1, 2001. In addition, the contract
      provides us with the option to acquire dark fiber strands in Germany
      and/or wavelengths in France.



UNDERSEA CABLES



    360ATLANTIC.  Our 7,600 route mile undersea cable between North America and
Europe cable project will have the capacity to be a 1.92 tbps, self-healing ring
that will connect landing sites in Boston, Halifax, Dublin and Liverpool and to
major gateway cities in Europe and North America, including London and New York.
In June 1999, we entered into a turnkey supply agreement with Tyco Submarine
Systems Ltd. ("Tyco") whereby Tyco will serve as the primary contractor for
360ATLANTIC, taking responsibility for the design, construction, installation
and testing of the cable. Tyco is a leading supplier of undersea communications
systems and services to various projects around the world. 360ATLANTIC's
self-healing ring design will have a capacity of 1.92 tbps on each segment using
4 fiber pair with state-of-the-art, 48-wavelength technology on each fiber pair.
Tyco is required to complete and deliver our 360ATLANTIC undersea cable by the
first quarter of 2001.



    360AMERICAS.  The planned 14,000 route mile undersea cable between South
America and North America we will acquire with the acquisition of GlobeNet will
have the capacity to be a 1.28 terabits per second, self-healing ring that will
be able to offer city-to-city connectivity between 6 major population centers in
Brazil, Venezuela, Bermuda and Argentina and the United States. Alcatel
Submarine Networks Inc. ("Alcatel") will serve as the primary contractor for
360AMERICAS on a turnkey basis, taking responsibility for the design,
construction and installation of the cable. Alcatel is a global leader in the
construction and installation of undersea fiber optic cables. Alcatel is
expected to complete and deliver the undersea portion of the 360AMERICAS cable
by the end of the second quarter of 2001.



    Among other conditions, the GlobeNet acquisition is subject to the approval
by a majority in number representing at least 75% in value of each of two
classes of GlobeNet shareholders present in person or by proxy and voting at a
separate meeting of each such class. Holders of over 75% of each class of
GlobeNet shares have entered into a voting agreement with GlobeNet and us to
approve the acquisition.



    We expect that some of GlobeNet's shareholders will purchase up to
$74.3 million of our Subordinate Voting Shares at the initial public offering
price.



FUTURE EXPANSION



    We believe that there may be opportunities in North America, Europe and
South America to further develop our network. We intend to expand our planned
network to more population centers through the addition of intercity and city
ring capacity in North America, Europe and South America. We are also reviewing
opportunities to expand the geographic reach of our network, including
transpacific connectivity to Asia.

COLOCATION FACILITIES



    NORTH AMERICA



    We have agreed, subject to execution of definitive agreements, to acquire
existing colocation facilities in two cities and site rights in seven other
cities totalling approximately 2.8 million square feet. These facilities are
expected to be completed by the end of 2001. In addition to the initial purchase
price of $156 million, of which $44 million is payable in our Subordinate Voting
Shares valued at the initial offering price, we anticipate spending
$400 million to complete the development of the facilities. Existing tenants
include major ILECs, CLECs and ISPs. There can be no assurance that we will be
successful in negotiating definitive agreements.



    EUROPE



    We have agreed, subject to execution of definitive agreements, to acquire
colocation facilities in four European cities, one of which is operational and
three of which are under construction. There can be no assurance that we will be
successful in negotiating definitive agreements.



PRODUCTS AND SERVICES



    We believe that our customers have a limited choice of independent service
providers capable of offering high-capacity, reliable, secure and cost-effective
services on a point-to-point basis between major population centers in North
America, Europe and South America. To meet our


                                       52
<PAGE>

customers' requirements, we offer a wide range of services on a scalable basis,
across an extensive geographic network, including:



NETWORK SERVICES



    The services we offer include:



    OPTICAL CHANNELS.  Dense wave division multiplexing ("DWDM") technology in
our network allows us to sell a customer exclusive long-term use of a portion of
the transmission capacity of a fiber optic strand rather than the entire strand.
We expect to be able to derive up to 160 individual wavelength channels at
either OC-48 or OC-192 per fiber pair. A purchaser of a wavelength may install
its own switching and routing equipment and has the choice of installing its own
protection equipment or use optical protection supplied as part of our service.
We offer the following services:


    - transparent OC-48 and OC-192 under IRU or lease;

    - optical ring protection; and

    - linear routes available, with add/drop along routes available.

    PRIVATE LINE TRANSMISSION.  We offer fixed amounts of point-to-point
connectivity. Our service has an advantage due to a low price point and flexible
commitment levels with higher reliability than is currently available on
traditional multiplexed services. We will offer these services through the sale
or lease of transparent connectivity up to OC-12.

    PACKET-BASED DATA SERVICES (IP TRANSPORT AND ATM).  We offer customers
variable capacity across our network to connect multiple service locations into
a single "Virtual Network" specific for each customer. Specific packet-based
services include ATM and IP transport.

    Our ATM service includes:

    - DS-3 to OC-48 interface rates;

    - all 5 classes of ATM service; and

    - switched virtual circuits available on customer premises equipment edge.

    Our IP transport includes:

    - protocol supports including Private Network to Network Interface ("PNNI"),
      ATM and packet over synchronous optical network technology ("SONET");

    - nodes in all major Internet-network access points; and

    - IP voice and modem transport and distribution, including virtual switching
      and compression.

    VIRTUAL VOICE TRUNKING.  We offer customers voice trunking services that can
be configured for sale as minutes of use. These services enable these customers
to originate and terminate long distance telephone calls connecting to local
exchange carriers ("LECs") with switched transport through our network. In
addition, we will provide our customers service on an as needed basis with
simple billing. The services we intend to offer include:

    - DS-1 to OC-3 structured services;

    - DS-0 switching and billing for usage;

    - transparent local interface;

    - SS7 signaling transport; and

    - advanced services, including compression.


    COLOCATION FACILITIES.  We intend to offer customers access and
interconnection to our network and services at various city points of presence
along our network. We will provide them with a variety of term and space
configurations ranging from secure cabinet rentals to longer term leases of cage
space.

NETWORK INFRASTRUCTURE

    DARK FIBER AND CONDUIT FOR SALE OR GRANT OF IRUS.  During the
pre-development and development stages of the network, we generally enter into
contracts with participants for the sale, lease or grant of IRUs for dark fiber
or conduit along one or more segments of the network. A typical contract for
sale currently provides for a sale price of $1,500 to $3,000 per fiber mile
(depending on geography and number of strands bundled together in the sale) and
requires a deposit upon execution of the contract. See "Risk Factors--Pricing
Pressures." Upon completion of the build, the participant is usually entitled to
a short period of time to test the system specifications and inspect the
shelters and other facilities (generally 15 to 20 days) prior to paying the
balance of the purchase price. In the case of a sale, title to the fiber or
conduit passes to the participant. An IRU is a long-term right of use, usually
of 10 to 20 years, with an option period for the user to renew at lower rates.
At the end of an IRU title may be passed to the user. The present value of the
initial contract term and extensions of an IRU usually equates to the comparable
sale price per fiber mile, which amount is generally paid in full at
commencement of the IRU.

    DARK FIBER AND CONDUIT FOR LEASE.  We lease dark fiber or conduit for a term
less than the period for which IRUs are typically granted. Leases are normally
structured with monthly payments over the term of the lease. We generally
realize a premium in lease pricing for bearing the risk that the lease will not
be renewed for the balance of the life of the asset.

    CONSTRUCTION SERVICES SUPPORTING THE DEVELOPMENT OF OUR NETWORK.  We are
continuing to construct and maintain fiber optic networks for third parties on a
contract basis. We focus on projects where we can retain fiber or conduit assets
on routes that complement and reduce the costs of completing the network or
where our construction services are connected to a sale of network capacity.

CUSTOMERS


    We are focused on providing our services to TSPs, ISPs, ASPs, SSPs and LORGs
with enterprise network needs. Typical targeted customers include a broad range
of companies, such as:


    - long distance companies;

    - incumbent local exchange carriers;

    - competitive local exchange carriers;

    - multi-service operators; and

    - local multipoint distribution service providers.

    Customers typically buy or lease fiber optic capacity with which they
develop their own communications networks or satisfy a need for redundant
capacity. The network provides such customers with a low-cost alternative to
building their own infrastructure or purchasing metered services from
communications carriers. Our customers can buy or lease fiber optic capacity on
a segmented basis or along our entire network.

SALES AND MARKETING


    We are building a highly motivated and experienced direct sales force and
customer care organization designed to capture new customers and to increase our
volume of business with existing customers. Because our target customers are
other TSPs, ISPs, ASPs, SSPs and LORGs with enterprise network needs, our sales
and marketing departments are focused and small compared to competitors that
have a broader retail strategy. Our direct sales organization consists of senior
level management personnel, experienced sales representatives and sales
engineers. Our sales force is made up of individuals with strong communications
and technical backgrounds which allows us to meet the needs of our target
customers. Direct sales tactics include direct contacts


                                       54
<PAGE>

with targeted ISPs and other potential corporate accounts by our sales
representatives and engineering support. In addition to helping to generate
initial sales, the sales engineer is responsible for ongoing technical support
and identifying new revenue opportunities with existing customers. Our sales and
marketing organization is segmented geographically between North America, Europe
and undersea to ensure they are able to meet the specific needs of their target
customers. We believe that the relationships established by our sales team and
management result in interactive exchanges that help us to design and market our
products in response to the needs of our potential customers.


    We believe that our new Chief Executive Officer brings additional valuable
relationships and contacts in the computer services, Internet, media and
financial communities in addition to traditional communications carriers that
will allow us to more easily gain access to these markets.

    NORTH AMERICA

    Our North American sales and marketing organization is divided into two
groups to meet the specific needs of our bandwidth customers and network
infrastructure customers.


    NETWORK SERVICES.  Our strategy is to target customers who have a need for
network services in areas covered by those portions of our network on which we
initially will be installing transmission equipment. We market a broad and
technically advanced range of network products and services. Consequently, we
are developing a dedicated sales and marketing team with the necessary technical
expertise.



    We commenced marketing our network services in the second quarter of 1999 to
targeted customers through a number of focused direct sales methods. Our
experienced sales team will qualify potential customers from their personal
contacts and direct sales efforts. In addition to our direct sales efforts, we
identify highly qualified prospective network customers through our network
infrastructure sales and marketing efforts. We also receive referenced
introductions from our suppliers when network requirements are identified while
they are making customer contacts in the process of doing their business. We
recently agreed to grant affiliates of PSINet an indefeasible right of use for
bandwidth capacity between Vancouver and Chicago, which we will deliver by the
end of March 2000, and to provide multiple dark fiber strands in eastern Canada
and the northeast corridor of the United States. We recently signed a contract
with Shaw Communications Inc. under which Shaw will lease bandwidth on
designated segments of our network between Edmonton and Toronto, and either
purchase dark fiber or acquire indefeasible rights of use on other network
segments for $153 million.


    NETWORK INFRASTRUCTURE.  Our strategy is to market to customers on a local,
regional and national basis. We market participation in infrastructure segments
of our network through personal contacts and relationships with prospective
customers, which consist primarily of large telecommunications companies. We
believe that we are known to most of our target customer group and that we have
good relations with them.


    Our current targeted customer base is comprised of approximately 200
companies. Most of our marketing and sales team have prior industry experience
with these companies, including MCI WorldCom, Inc. ("MCI WorldCom"), Sprint
Corporation ("Sprint"), AT&T Corp. ("AT&T"), Qwest Communications International
Inc. ("Qwest") and US West. In addition, as a result of our more than ten years
of experience in constructing fiber optic networks, our management also has
long-standing relationships in the telecommunications industry. We are also able
to identify potential participant and co-development customers that initially
approach us because of our reputation and experience in the design, construction
and development of fiber optic facilities.


                                       55
<PAGE>
    EUROPE


    NETWORK SERVICES.  Our strategy in Europe is to target customers by specific
geographic regions who have a need for network services in areas covered by
those portions of our network. In Europe, we intend to build out separate sales
and marketing organizations by region to enable us to address the specific
market, product and regulatory needs of our customers. Initially, we intend to
have regional offices in England, France, Germany and Scandinavia and will add
additional offices as we expand our European network. Each sales and marketing
managing director will report directly to our head of European sales and
marketing who will be responsible for coordinating our European efforts with our
North American and overseas teams. This structure will allow us to provide our
customers seamless service from anywhere in Europe to anywhere in North America.
We recently signed a contract with an affiliate of PSINet to deliver high-speed
bandwidth services from New York to London.



    UNDERSEA CABLES



    Our cable projects have been designed to be responsive to potential
customers' concerns, including the offer of diverse routes and landing sites,
protected capacity on two separate cables, seamless city-to-city availability
using our extensive backhaul terrestrial network and a firm, near-term delivery
date. In North America we have teams segregated by service provision type and in
Europe geographically by country. We are currently developing our sales
organization in the United States, Europe and South America to market and
distribute capacity on our cable. In addition to our direct sales efforts, we
have received referenced introductions from our suppliers.


    Our pricing strategy is to offer capacity at the lowest cost in the market
to our initial customers and reflects our belief that large buyers of capacity
will seek significant discounts and flexible payment terms in order to contract
for purchases prior to the ready-for-service date. We are offering a program
which gives initial buyers of capacity the option to make additional purchases
on system upgrades, at a cost which is a significant discount to current market
prices. Similarly, our proposed pricing of ongoing operations and maintenance
services reflects significant volume discounts and lower prices for upgrade
capacity versus the flat unit pricing traditionally offered in the marketplace.

NETWORK DESIGN AND INFRASTRUCTURE

    Our network utilizes state-of-the-art technologies based on DWDM optics and
packet-switched routing. This approach greatly reduces the complexity and number
of component systems that previously were required to deliver voice and data
services. Our network has the following characteristics:

    ADVANCED FIBER OPTIC CABLE.  Our network benefits from technologically
advanced fiber optic cable, including Corning E-leaf and single mode fiber that
allows us to expand our DWDM system to maximize the potential of DWDM
technologies.

    DENSE WAVE DIVISION MULTIPLEXING.  DWDM allows for increased network
capacity through the transmission of multiple waves of light over a single fiber
optic strand. Our DWDM optical system electronics are installed in shelters and
POPs in carrier interconnect locations along the route. Each route includes
several spans that are comprised of optical terminals at the ends of the span
and a combination of optical line amplifiers, electrical signal regeneration and
optical add/drop terminals to complete the path. Each system operates on a
single fiber providing bi-directional transport of up to 160 channels of OC-192
(10 gbps) wavelengths. The current network plan calls for a minimum of four
OC-48 channels per route, with four OC-192 channels installed in routes where we
believe that there will be sufficient market demand.

    OPTICAL TECHNOLOGY.  Our network's optical design will enable us to upgrade
installed equipment or to add new equipment to any segment of the network. Our
initial optical platform will

                                       56
<PAGE>
have a capacity of 32 wavelengths at 2.5 gbps or 10 gbps expandable to 160
wavelengths. We will use optical ring protection devices where a customer
requires redundant services.


    ATM CORE SWITCHING AND PROTECTION.  In place of the SONET equipment used by
older network architectures, we have chosen to use ATM as both the protection
and the switching layers to deliver services in addition to optical channels
derived on the DWDM equipment. ATM core switching is a packet-based switching
and transmission technology which sends various types of information, including
voice, data and video, in fixed-size cells. We utilize advanced equipment by
Marconi plc which enables packet-based networks to carry voice and data more
efficiently and at a lower cost than traditional voice and data networks. The
initial core switches have a throughput capacity of 40 gbps and network link
speed of 2.5 gbps.


    The ATM packet elements use multiple optical channels connecting directly to
the DWDM equipment providing meshed topology, a method of circuit protection
that is more reliable than a simple ring topology. The use of the PNNI
hierarchical routing protocol collects circuits into virtual paths and greatly
reduces the number of channels that the ATM switch is required to restore in the
event of an optical failure. This approach allows for the scalability and the
restoration timeframes that are as good as, or better than, those of a
traditional SONET-based architecture. Due to the nature of the ATM
configuration, all of the circuits are fully protected and there are no single
points of failure other than the customer connection port. This enables us to
offer traditional as well as dedicated IP services with guaranteed availability
in excess of 99.9% compared to the market standard of 99.7%.


    MULTI-SERVICE PLATFORM.  Our multi-service operating systems allow voice,
data and Internet services to be provided using a single ATM operating system.
Most communications service providers in North America, South America and Europe
use multiple platforms for the provision of different services, which create
distinct networks and increased operating and capital costs for each service
provided.


NETWORK OPERATIONS CENTER


    The Network Operations Center ("NOC") is the human service connection
between our customers and the technology that ultimately delivers their
services. Pursuant to an agreement with Urbanlink, we have the services of a NOC
in Vancouver 24x7. We will have redundant network services through Nortel until
June 30, 2000. As a result of the GlobleNet acquisition, we will have an
additional NOC in Bermuda that we intend to use to support the 360AMERICAS
cable.



    We are in the process of designing our NOC in Dublin, Ireland. Our Dublin
NOC will be primarily responsible for European operations and will be on line in
October 2000. Each NOC will serve as a back up to the other.



    In addition to the two main NOCs in Vancouver and Dublin, we are also
designing support centers in Denver to maintain North American cable operations
and the 360ATLANTIC cable. The NOCs allow us to provide the following services:


    - directing the repair efforts of cable restoration, optical and ATM system
      repairs and maintenance;

    - providing network management for the optical and ATM elements;

    - providing POP and customer record management; and

    - providing circuitry for customer and internal circuits.

    We are using a design based on IP technology that integrates all of the
alarm and monitoring of the network elements into an adaptive fabric to satisfy
our service level agreements. With this technology, access to the network
management layer is not restricted to the physical NOC as full operations
capabilities may be located at multiple locations. This allows us to extend
particular management services to our customers in a secure and reliable way.

                                       57
<PAGE>
NETWORK CONSTRUCTION


    The portions of our network constructed by us are designed to maximize
expandability and flexibility. Generally, at least 144 fiber optic strands will
be installed on major builds throughout the network. In high demand areas, 264
fibers or more may be installed in order to meet anticipated demand as well as
to enable us to swap fiber for fiber in other geographic areas both in the North
American market and internationally.



    Our network installation process along railroad ROW combines traditional
railroad activities and modern engineering and building techniques. Conduit and
fiber on railroad ROW is generally installed with our patented railplow. The
railplow reduces the time necessary to install network infrastructure on
railroad ROW because it allows movement of construction crews on and off the
tracks on short notice to allow trains to pass. As a result, we can construct
networks on railroad ROW much more quickly and efficiently than our competitors
who use traditional plow trains, which are not able to move on and off railroad
tracks on short notice. Each of Ledcor and us currently owns 50% of the common
shares of a holding company that owns the patent to the railplow and we have
received a commitment that a royalty-free, exclusive worldwide license to use
the railplow will be granted to us. In some circumstances, our ownership of this
company would be subject to change and our license would become non-exclusive.


    For routes not using railroad ROW, we use tractor plows. Tractor plows are
tractor-pulled plow vehicles equipped to plow trenches and install conduit.
Tractor plows also may be used in some places along railroad ROW, depending on
space, availability of track time and other factors. These tractor plows
generally perform the same functions as railplows. Many of the skills developed
in connection with the installation of fiber optic cable along railways are
transferable to non-rail installations.

    If fiber or conduit must be laid across a bridge or through a tunnel, we
typically place the conduit in a galvanized steel pipe that is attached to the
side of the bridge or along the tunnel floor or wall. When necessary to install
fiber or conduit under rivers or other obstructions, we use directional boring
techniques to bore small tunnels underneath the river or obstruction and feed
the conduit through the tunnel.


    After the conduit has been buried (or attached to a bridge or tunnel) and as
a segment nears completion, the fiber optic cable is installed or "jetted"
through the conduit. This is accomplished through the use of access boxes that
are installed along the network at approximately four to five mile intervals.
The access boxes also allow for the making of repairs, replacement of fiber and
installation of additional fiber. The access boxes typically contain an
additional loop of fiber optic cable to provide slack in the system to
accommodate displacement, disruption or movement of the conduit as a result of
digging or excavation activities, floods, earthquakes or other events. The
presence of additional fiber optic cable reduces the risk that the cable will be
cut or broken.


    We design and manufacture regeneration shelters that are installed along our
network at an average of 45 mile intervals. These shelters are secure,
climate-controlled structures with an individual compartment for each
participant to install its optical transmission equipment and related
electronics.

    The optical system electronics are installed in the shelter compartments
described in the preceding paragraph. Each route includes several spans that use
Optical Terminals at each end of the span and Optical Line Amplifiers,
regeneration shelters and Optical Add/Drop between Optical Terminals. Each
linear route includes a redundant system for reliability and maintenance. In the
case of diverse parallel routes, one of the parallel routes will include a
redundant system for additional reliability and system maintenance.

                                       58
<PAGE>
RIGHTS-OF-WAY AND PERMITTING


    To implement our business plan successfully, we must obtain licenses and
permits from third-party landowners and governmental authorities and complete
particular regulatory filings to permit us to install conduit and fiber. ROW are
generally non-exclusive. Where possible, we lease them under multi-year
agreements with renewal options. ROW agreements and permits provide a
contractual interest and do not create an interest in land. See "Risk
Factors--Need for Rights-of-Way." In the ordinary course of business each build
requires us to either obtain, lease, cure (or condemn) ROW or design re-routes,
on a daily basis. For example, to complete the Seattle-Portland segment of the
West Coast Build we obtained ROW agreements and permits from more than 700
individual landowners and local authorities. Alternative ROW for some route
miles must be identified, negotiated and obtained in the event that the original
route cannot be secured.


    It is also possible to obtain ROW in bulk. The majority of the ROW for the
FOTS was obtained from two Canadian railways. In June 1999, we announced
agreements with CN and IC which provide access to over 950 track miles in the
United States and 2,900 track miles in Canada which we believe will
substantially satisfy the ROW and permit requirements for the Central and
Northeast Builds. We believe that these ROW will be valuable to us, particularly
with the advantages of the railplow and the ROW's geographic location. The ROW
obtained from each of CN and IC may be subject to legal challenge. See "Risk
Factors--Need for Rights-of-Way."


    In Europe, all of our current and planned network assets have been acquired
through purchases or swaps of North American fiber optic cable, so there has
been no need thus far to obtain ROW in Europe. For 360ATLANTIC we have applied
for licenses with the governing authorities in each of Ireland, Canada, the
United Kingdom and the United States. The licenses have been granted in the
United States, Ireland and the United Kingdom. One license for which we applied
in Canada has been approved and a second license application in Canada is
pending. We also applied for various permits and consents for 360ATLANTIC in
Ireland, Canada, the United Kingdom and the United States. Approximately 45% of
these permits and consents have been granted and the remaining 55% are pending.
While there can be no assurance that the remaining licenses, permits and
consents will be granted, we do not anticipate any problems at this time.


SUPPLIERS


    The principal components of our network are fiber optic cable and conduit.
For those portions of our network that we construct ourselves, we purchase such
fiber optic cable and conduit from third-party suppliers. Fiber optic cable
suppliers generally require three to six months lead time for large orders,
while conduit is generally available on a spot basis from numerous suppliers.
Although in the past we have purchased cable from a single supplier, there are a
number of alternative suppliers from whom we regularly obtain quotes which are
competitive on price, delivery and specifications.


    We currently purchase the optical components from a single vendor. A number
of alternative suppliers have been identified from which it would be possible to
purchase the optics required to complete a new system with only minor changes to
the design of the NOC. With respect to the provision of ATM switches, we have
adopted a dual supplier approach.

COMPETITION

    The telecommunications industry is extremely competitive particularly
concerning price and service. It is relatively common for TSPs to be both
customers and competitors. This is a concept referred to as co-opetition.
Therefore, we face competition and co-opetition from existing and planned TSPs
and customers on each of our planned routes. We compete primarily on the basis
of price, availability, transmission quality and reliability, customer service
and the location of our systems.

    We believe that our competitive advantages in North America, Europe and
South America will be our ability to enable our customers to establish and
maintain a strong competitive position in providing services to their end users.
We believe that independence, services designed for the wholesale market and
simple billing systems will enable us to gain a significant position in this
market niche. We believe that our competitive advantages in providing our
undersea cable include our ability to provide end-to-end connectivity between
major North American, European and South American cities and attractive pricing
of capacity by initial purchasers of capacity.



    There are currently several communications companies with long distance and
city ring fiber optic networks and colocation facilities in North America,
Europe, South America and Asia. In North America, these include companies such
as Level 3 Communications, Inc. ("Level 3"), Qwest and Williams Communications
Group, Inc. ("Williams"). In Europe, these include companies such as MCI
WorldCom, Global Crossing Ltd. ("Global Crossing"), Global TeleSystems Europe
B.V., Viatel Inc., KPNQwest N.V., Colt Telecom Group plc, Energis plc and
Carrier 1 International S.A. In South America, these companies include IMPSAT
Corporation and Telemar.



    We believe that other companies are planning networks that, if constructed,
could employ advanced technology similar to that of our network. These
competitors, as well as traditional carriers, including AT&T, MCI WorldCom,
Sprint (MCI WorldCom and Sprint have recently entered into an agreement to
merge) Deutsche Telekom AG, France Telecom S.A., British Telecommunications plc,
Mannesmann AG and Cable & Wireless plc, may compete directly with us for
customers.



    UNDERSEA CABLES



    360ATLANTIC.  The route addressed by 360ATLANTIC is currently served by
several undersea cables. We anticipate that we will face competition primarily
from new transatlantic cable systems, including:


        (i) AC-2, a transatlantic cable system which is being developed by
    Global Crossing;

        (ii) FLAG Atlantic, a 50/50 joint venture between Global
    Telesystems Inc. and Flag Telecom;

        (iii) Level 3's linear Yellow cable project; and


        (iv) Tyco International Ltd.'s proposed transatlantic cable project.



    Three of these systems, including 360ATLANTIC, will have fully protected
ring designs. 360ATLANTIC will be the first of the new systems to be ready for
commercial service, and will be competing for clients directly with the other
two new ring systems.



    360AMERICAS.  We anticipate that we will face competition from the following
cable systems, all of which are currently under construction:



    - Americas-2, a new carriers' consortium cable system with a scheduled ready
      for service date in the first half of 2000 that will connect Brazil,
      Venezuela, Florida and the Carribean;



    - South American Crossing, a new self-healing ring cable system being
      developed by Global Crossing Ltd. that will link coastal countries in
      South America to Global Crossing's planned Mid-Atlantic Crossing in St.
      Croix, U.S.V.I. and Global Crossing's planned Pan American Crossing in Ft.
      Amador, Panama; and



    - The SAm-I cable system, a self-healing ring cable system being developed
      by Telefonica Internacional S.A. and Tyco International Ltd. that will
      connect the United States, Guatemala, Brazil, Argentina, Chile, Peru and
      Colombia.


EMPLOYEES

    As of December 31, 1999, we had approximately 1,000 full-time and seasonal
employees. Depending upon the level of development or construction activity, we
will increase or decrease our work force. Generally, non-management employees
from Canada are covered by a collective

                                       60
<PAGE>
bargaining agreement with the Christian Labor Association of Contractors, which
expires on February 28, 2001 and is automatically renewable unless either party
gives prior notice. We believe that our work force is highly capable and
motivated and that our relations with our employees are good. In connection with
the construction and maintenance of our fiber optic networks, we may use
third-party contractors to meet excess demand and harness local construction
knowledge, some of whose employees may be represented by other unions or covered
by collective bargaining agreements.

PROPERTIES


    We have executive and administrative offices in Vancouver, British Columbia
and Seattle, Washington. We also have administrative, sales, engineering and
operations offices located in Vancouver, Denver and Toronto. In addition to the
NOC located in Vancouver, British Columbia, we have a NOC located in Dublin,
Ireland.


    All of our offices are leased on a short-term basis except for our Toronto
office, which we occupy under a lease expiring in 2009. We expect to open
additional offices in multiple jurisdictions globally as required.

LEGAL PROCEEDINGS


    From time to time, we may be a party to various legal proceedings arising in
the ordinary course of our business. We are not party to any material legal
proceedings.



    In July 1999, after issuing a Certificate of Public Convenience and
Necessity ("CPCN") to Worldwide Fiber Networks, Inc. ("360-NI"), the California
Public Utilities Commission ("CPUC") issued a "stop work" order which required
us to submit an environmental assessment to comply with the California
Environmental Quality Act. We complied with this order and submitted the
required information. On January 6, 2000, the CPUC issued an order modifying the
CPCN, authorizing the recommencement of construction and adopting a mitigated
negative declaration imposing certain conditions on continued project
construction. We have since recommenced construction in compliance with the
terms of the CPUC order and do not expect that such compliance will have any
material delaying effect on ongoing construction. The CPUC retained jurisdiction
in further proceedings to determine the amount, if any, of civil penalties that
may be imposed upon us for construction that occurred in California prior to the
"stop work" order. This proceeding is ongoing, and we presently have no estimate
of any fines or penalties that may be imposed. The maximum allowable penalty
permitted by the California Public Utilities Code would be $3.6 million for the
period between December 2, 1998 and July 6, 1999.


PATENTS


    The patent for the railplow is owned by a company which is 50% owned by
Ledcor and 50% owned by us. We have a non-exclusive license in North America for
the use of the railplow. Ledcor has committed to cause a worldwide exclusive
license to be granted to a subsidiary of ours. This license would cease to be
exclusive after a change of control of 360NETWORKS INC. See "Relationships and
Related Party Transactions--Transactions with Ledcor--Description of
reorganization and related agreements--Railplow." As we develop value-added data
services we intend, when appropriate, to seek patents and other intellectual
property protection on an on-going basis. We currently do not have patentable
rights with respect to any value-added data services, and we cannot assure you
that we will in the future develop any such rights.

</TABLE>


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

(1) The options are exercisable in four equal annual installments commencing on
    June 30, 1999.

STOCK OPTION PLAN


    Our 1998 Long Term Incentive and Share Award Plan (as amended) permits the
grant of non-qualified stock options, incentive stock options, share
appreciation rights, restricted shares, restricted share units, performance
shares, performance units, dividend equivalents and other share-based awards to
employees and directors of ours or of our affiliates and subsidiaries. Any other
person who provides ongoing services to us or our affiliates is also eligible
for an award under the plan. A maximum of 71,133,008 Subordinate Voting Shares
may be subject to awards by us under the plan, and the maximum number of
Subordinate Voting Shares for which options and share appreciation rights may be
granted by us during a calendar year to any eligible person under the plan is
8,000,000. The number of Subordinate Voting Shares issued or reserved pursuant
to the plan (or pursuant to outstanding awards) is subject to adjustment on
account of share splits, share exchanges, mergers and other changes in the
Subordinate Voting Shares, to prevent dilution or enlargement of a participant's
rights under the plan. If any grants under the plan are cancelled, surrendered
or otherwise terminated without a distribution of Subordinate Voting Shares,
then those shares will again be available for further awards by us under the
plan.


    ADMINISTRATION


    The plan is administered by the compensation committee of our board of
directors, which may delegate its duties and powers to officers or managers of
ours or of our affiliates and subsidiaries. Our compensation committee has the
sole discretion to determine the eligible persons to whom awards may be granted
under the plan, the type and number of awards to be granted, and to what extent
an award may be settled in cash, Subordinate Voting Shares, property or other
awards.


    OPTIONS


    The plan permits our compensation committee to grant rights to purchase
Subordinate Voting Shares. The exercise price for each option granted under the
plan is set by the compensation committee. Unless otherwise determined by our
compensation committee, the term of each option will be ten years from the date
of the grant and the option will become exercisable in four equal annual
installments beginning on the first anniversary of the date of the grant.


    Incentive stock options may be granted to our employees and those of our
subsidiaries, while non-qualified stock options may be issued to all eligible
participants. Any incentive stock options that are awarded by our compensation
committees will comply in all respects with Section 422 of the U.S. Internal
Revenue Code.

                                       68
<PAGE>
    SHARE APPRECIATION RIGHTS


    Our compensation committees may grant share appreciation rights independent
of or in connection with an option. Each share appreciation right will entitle a
participant upon exercise to an amount equal to the excess of (1) the fair
market value on the exercise date of one Subordinate Voting Share over (2) the
exercise price of the share appreciation right as determined by our compensation
committees as of the date of grant of the share appreciation right. Payment will
be made in Subordinate Voting Shares, cash or property, as specified in the
award agreement or as determined by our compensation committee.


    RESTRICTED SHARES


    Restricted shares awarded by our compensation committees under the plan will
be subject to restrictions on transferability and other restrictions. The
restrictions will lapse as our compensation committee determines. If the
employment of a holder of restricted shares is terminated during a restriction
period, any Subordinate Voting Shares then subject to restrictions, and any
accrued and unpaid dividends, or dividend equivalents, will be forfeited unless
our compensation committee waives the forfeiture. Except to the extent
restricted by the award agreement, holders of restricted shares will have the
right to vote the restricted shares.


    RESTRICTED SHARES UNITS


    Our compensation committee may grant a right under the plan to receive
Subordinate Voting Shares or cash at the end of a specified period. Our
compensation committee may impose additional restrictions on the restricted
share units. If employment of a participant is terminated, or upon failure to
satisfy other conditions precedent to the delivery of cash or Subordinate Voting
Shares under the grant, all restricted share units still subject to a
restriction will be forfeited unless our compensation committee waives the
forfeiture.


    PERFORMANCE SHARES AND PERFORMANCE UNITS


    The plan permits our compensation committee to make awards based on the
attainment of performance objectives set by the committees for a performance
period of one or more years. At the beginning of a performance period, our
compensation committee will determine the range of Subordinate Voting Shares, in
the case of performance shares, and the range of dollar values, in the case of
performance units, which will be paid if the relevant measure of performance is
met.


    DIVIDEND EQUIVALENTS


    Our compensation committee may grant dividend equivalents under the plan
which give the participant the right to receive cash, Subordinate Voting Shares
or other property equal in value to dividends paid with respect to a specified
number of Subordinate Voting Shares. Dividend equivalents may be awarded by our
compensation committee alone or in connection with another type of award and may
be paid concurrently or on a deferred basis.


    OTHER SHARE BASED AWARDS


    The plan permits our compensation committee, subject to limitations under
applicable law, to grant to eligible persons awards that may be denominated or
payable in, valued in whole or in part by reference to, or otherwise based on,
or related to, Subordinate Voting Shares as deemed by our compensation committee
to be consistent with the purposes of the plan.


                                       69
<PAGE>
    TRANSFERABILITY


    Unless otherwise determined by our compensation committee, awards granted
under the plan are not transferable other than by will or by the laws of descent
and distribution.


    CHANGE IN CONTROL

    In the event of a change of control (as defined in the plan), all
outstanding awards then held by participants which have restrictions or
limitations shall become fully exercisable at the time of the change of control,
and all performance criteria and other conditions to the payment of awards will
be deemed to be achieved and will be waived by us at the time of the change of
control.

    AMENDMENT AND TERMINATION

    Our board of directors may amend, alter, suspend, discontinue or terminate
the plan in any respect, at any time, without the consent of holders of awards
or our shareholders (except to the extent shareholder approval is required by
Section 422 of the U.S. Internal Revenue Code), PROVIDED, HOWEVER, no amendment,
alteration, suspension, discontinuation, or termination of the plan may
materially and adversely affect the rights of a holder of an award and without
his or her consent.

                       PRINCIPAL AND SELLING SHAREHOLDER


PRINCIPAL SHAREHOLDERS


    The following table describes the beneficial ownership of our Class C
Multiple Voting Shares as of February 25, 2000 pro forma for the 2 for 1 split
of our shares by (i) each person or company known by us to own more than 10% of
our Class C Multiple Voting Shares, and (ii) all of our directors and officers
as a group. As of February 25, 2000, there were 81,840,000 Class C Multiple
Voting Shares outstanding.


    To calculate a shareholder's percentage of beneficial ownership, we must
include in the numerator and denominator those shares underlying options
beneficially owned by that shareholder. Options held by other shareholders,
however, are disregarded in this calculation. Therefore, in both this table and
the following table, the denominator used in calculating beneficial ownership
among our shareholders may differ.

(1) Concurrent with the closing of this offering, we will reorganize our share
    capital. Pursuant to this reorganization, the Class C Multiple Voting Shares
    will be redesignated as Multiple Voting Shares. See "Description of Capital
    Stock and Share Capital Reorganization."



    Worldwide Fiber Holdings Ltd. is an indirect, wholly owned subsidiary of
Ledcor Inc. David and Clifford Lede own, in the aggregate, more than 50% of the
outstanding shares of Ledcor Inc. The shares of Ledcor Inc. are not publicly
traded in the United States or Canada. Larry Olsen, our Vice Chairman and Chief
Financial Officer, and Madison Square Inc. a corporation caused to be formed by
Stephen Stow, our Executive Vice President; Managing Director, Asia ("Madison
Square"), each presently has the irrevocable right to buy ("IRTB") from
Worldwide Fiber Holdings Ltd. and Ledcor Limited Partnership 5% of our shares
owned by such entities. The numbers in the tables above and below do not reflect
this right. Mr. Stow disclaims beneficial ownership of the shares owned by the
corporation caused to be formed by him.


SELLING SHAREHOLDER


    The following table describes the ownership of our Class A Non-Voting Shares
by our selling shareholder as of February 25, 2000 and as adjusted to reflect
(i) the sale of Class A Non-Voting Shares by such selling shareholder in the
offering and (ii) the 2 for 1 split of our shares. As of


                                       71

February 25, 2000 there were 353,426,400 Class A Non-Voting Shares outstanding
and 150,951,312 Class A Non-Voting Shares issuable upon conversion of all
outstanding Preferred Shares.

                  RELATIONSHIPS AND RELATED PARTY TRANSACTIONS


TRANSACTIONS WITH LEDCOR


    DESCRIPTION OF REORGANIZATION AND RELATED AGREEMENTS


    Effective May 31, 1998, we entered into a series of agreements with Ledcor
to purchase the equipment, fiber optic strands and some other assets related to
the business of Ledcor Industries' telecommunications division. As part of the
reorganization, we also entered into the construction services agreements to
complete a construction project for Ledcor. Effective August 31, 1998, Ledcor
transferred to us their 50% interest in 360-USA and, in February 2000, 360-USA
became our wholly owned subsidiary.


    The material agreements we entered into with Ledcor in connection with the
reorganization are as follows:

    RAILPLOW.  Effective May 31, 1998, the patent for the railplow which we use
in connection with the construction of some portions of our network on railroad
ROW were transferred to a subsidiary of Ledcor that we refer to as "Patent Co.,"
and we were concurrently granted a non-exclusive license for its use at our
request. Effective December 1, 1998, one of our subsidiaries acquired 50% of the
shares of Patent Co. Ledcor has agreed to cause Patent Co. to grant to us a
royalty-free worldwide exclusive license for the use and other exploitation of
the plow technology. The license will cease to be exclusive six months after a
change of control of us. The shareholders agreement relating to Patent Co.
provides that Ledcor and our subsidiary have the option to acquire the other
party's shares of Patent Co. if the other party becomes insolvent, bankrupt or
subject to a change of control.


    MANAGEMENT SERVICES AGREEMENT.  We currently receive immaterial amounts of
management staff, administrative and other support pursuant to a management
services agreement with Ledcor. Under this agreement, prior to January 1, 2000
we reimbursed Ledcor for some of the related costs and paid a monthly fee of
Cdn.$200,000. Beginning January 1, 2000, the Cdn. $200,000 monthly obligation
was eliminated. This agreement is terminable at any time by either party.



    EMPLOYEE SERVICES AGREEMENTS.  We were previously a party to two employee
services agreements with Ledcor. Under these agreements, Ledcor provided us with
personnel for the design, engineering, construction and installation of the
network, and we reimbursed Ledcor for the direct costs of these personnel. These
agreements have terminated.



    CONSTRUCTION SERVICES AGREEMENTS.  We were previously party to construction
services agreements with Ledcor under which we agreed to provide fiber optic
network construction services to Ledcor and fulfill Ledcor's fiber optic network
construction commitments for some builds. We also agreed to procure the
requisite insurance necessary for these builds and perform all work in strict
compliance with the appropriate contract and applicable laws. In addition, we
agreed to indemnify Ledcor for particular losses, liabilities, damages and
claims that may arise under the agreements. In return, Ledcor paid us an amount
equal to costs incurred plus 15% of our total costs. Either party may terminate
these agreements at any time. Our obligations under these agreements were
complete by the end of January 1999.


    NON-COMPETE AGREEMENT.  Ledcor has agreed not to compete with us in the
business of developing or constructing fiber optic communications infrastructure
for a period ending on the earlier of May 31, 2008 and six months after a change
of control of us.


    SALE AND TRANSFER AGREEMENTS.  We entered into a series of agreements that
transferred equipment and other assets of Ledcor Industries' telecommunications
division including a minimum of 12 strands of dark fiber along Ledcor
Industries' project across Canada and the northeast United States.


                                       73
<PAGE>

PURCHASE OF SHARES OF 360-USA



    Effective August 31, 1998, each of Ledcor and Mi-Tech transferred their 50%
interest in 360-NI to 360-USA, a newly incorporated Nevada corporation. In
exchange, each of Ledcor and Mi-Tech acquired 50% of the common shares of
360-USA. At the same time, Ledcor exchanged with 360-USA a promissory note in
the amount of $3,915,000 payable by 360-NI to Ledcor for a promissory note of
the same face value payable by 360-USA to Ledcor. In addition, Mi-Tech exchanged
with 360-USA a promissory note in the amount of $7,231,230 payable by 360-NI to
Mi-Tech for a promissory note of the same face value payable by 360-USA to
Mi-Tech.



    In a subsequent series of transfers, also effective August 31, 1998, Ledcor
transferred to us their shares of 360-USA and the $3,915,000 promissory note
payable by 360-USA to Ledcor. In exchange, we issued additional shares and a
promissory note of the same face value to Ledcor.



    In March 2000, we agreed with Mi-Tech to acquire its remaining 25% interest
in 360-USA for 18,352,941 Subordinate Voting Shares.


    ACQUISITION, CONSTRUCTION AND CONSTRUCTION MANAGEMENT OF FIBER OPTIC NETWORK
    ASSETS

    On September 27, 1999, we concluded a transaction with Ledcor whereby we
acquired particular fiber optic network assets in consideration of the issue of
36,000,000 of our Class C Multiple Voting Shares. In addition, we assumed
defined rights and obligations of the affiliates under their build agreements
with a third party, including obligations relating to the completion of those
builds and particular support structure, maintenance, license and access and
underlying rights obligations.

    On June 25, 1999, we concluded a transaction with Ledcor whereby Ledcor
would complete an approximate 156-mile portion of the fiber optic build between
Portland and Sacramento for approximately $23.7 million.


    Effective as of May 1, 1999, we concluded a transaction with Ledcor whereby
personnel of Ledcor who were involved in the designing and planning of the
360ATLANTIC cable stations will oversee management and supervision of
construction of these facilities for a fee of approximately $1.7 million.



    CANADIAN TELECOMMUNICATIONS ARRANGEMENT



    Concurrent with the completion of the offering, we will conclude a series of
transactions to transfer our Canadian telecommunication transmission facilities
and certain related facilities to Urbanlink. The arrangement allows 360NETWORKS
to issue voting, as opposed to non-voting, shares in connection with the
offering and allows us to more easily expand our operations globally through
acquisitions. A subsidiary of Ledcor will own 66 2/3% of the voting
non-participating shares and 49% of the non-voting participating shares of the
holding company which will wholly own Urbanlink, and we will own 33 1/3% of the
voting non-participating shares and 51% of the non-voting participating shares
of that company. To acquire its non-voting participating shares, Worldwide Fiber
Holdings Ltd., ("WFHL") will contribute Subordinate Voting Shares of
360NETWORKS. Concurrent with the closing of the arrangement we will enter into
certain non-exclusive resale arrangements with Urbanlink, under which we will
receive bandwidth capacity for resale purposes, a NOC Operating Agreement
pursuant to which Urbanlink will operate the Vancouver NOC and a Shareholders
Agreement with the subsidiary of Ledcor that requires us to purchase the shares
of the holding company in the event of a change in the TELECOMMUNICATIONS ACT
(Canada) that eliminates the requirement that Canadian telecommunications
carriers be owned and controlled by Canadians. We will contribute certain
telecommunications assets under construction to Urbanlink in the future and WFHL
will contribute additional Subordinate Voting Shares.


                                       74

    LEASES

    Ledcor leases our facilities in Toronto to us for approximately $825,000 per
year under agreements that expire in 2009.

    BACKGROUND OF LEDCOR

    Ledcor, established in 1947, is among the largest diversified construction
companies in Canada and has substantial experience as a construction contractor
in the United States. Ledcor's core business activities, in addition to the
activities of the telecommunications division, are pipeline and civil
construction and diversified contracting, including major commercial and
industrial buildings and industrial and mining projects. Ledcor reported
revenues of more than Cdn.$900 million for the fiscal year ended August 31, 1999
from all activities, with significant contribution from the telecommunications
division.


    Ledcor began designing, engineering and constructing buried long distance
power generation and fiber optic telecommunications systems more than ten years
ago and has installed fiber optic cable networks on a contract basis for
numerous telecommunications companies, including Bell Canada, MTS Netcom Inc.,
AT&T, AT&T Canada, Alaska Fiber Star, FONOROLA Inc., Mi-Link Communications,
LLC, Champlain Telephone Company and World Net Communications Inc.



    In 1996, Ledcor installed its first fiber optic cable as a developer between
the cities of Edmonton and Calgary, Alberta. Ledcor sold fiber strands of this
cable, on a "condominium" basis prior to construction, to FONOROLA, Sprint
Canada and AT&T Canada. After the successful completion of this project, Ledcor
began, as a developer, the first trans-Canadian fiber optic cable network.


    The foundation of Ledcor's success and growth over the last 52 years has
been built on the strength of its dedicated people, ability to control costs and
its conservative but entrepreneurial approach to business. Ledcor believes it
has maintained an excellent reputation for the quality of its products and
services in its markets and enjoys substantial repeat business from major
customers.


TRANSACTIONS WITH CANADIAN NATIONAL



    In March 2000, we acquired the minority interest of each of 360-CN and IC
Holdings, as a result of which we issued to CN 9,411,765 Subordinate Voting
Shares, subject to adjustment based on the number of Subordinate Voting Shares
issued to certain other parties and based on the total value of Subordinate
Voting Shares issued in this transaction (based on the initial public offering
price) being not less than $100 million and not more than $160 million. In
addition, Claude Mongeau, a Senior Vice-President and the Chief Financial
Officer of CN, recently became one of our directors.


PURCHASE OF SHARES BY CHIEF EXECUTIVE OFFICER


    On December 22, 1999, Gregory Maffei purchased 52,160,000 of our Class A
Non-Voting Shares and 9,840,000 of our Class C Multiple Voting Shares for
$77.5 million, representing approximately 8% of our total equity diluted on a
fully diluted basis. To facilitate the sale, we advanced an amount equal to the
purchase price to Mr. Maffei under a limited recourse note maturing on
December 22, 2005. The note will mature, in whole or in part, as a result of the
sale of our shares by Mr. Maffei or Mr. Maffei's ceasing to be employed by us.



    We have the right to repurchase certain of Mr. Maffei's shares at the
original purchase price plus the pro rata amount of interest accrued on the note
in the event Mr. Maffei's employment with us is terminated before June 30, 2003.
In addition, Mr. Maffei has the right to require the repurchase of some or all
of his shares by us or, at our option, Worldwide Fiber Holdings Ltd.



IRREVOCABLE RIGHTS TO BUY



    Larry Olsen, our Vice Chairman and Chief Financial Officer, and Madison
Square, each presently has the irrevocable right to acquire from Worldwide Fiber
Holdings Ltd. and Ledcor Limited Partnership up to 5% of our shares owned by
each and to participate pro rata in sales of shares made by those entities.

                          DESCRIPTION OF CAPITAL STOCK
                        AND SHARE CAPITAL REORGANIZATION



    Concurrent with the closing of the offering, we will reorganize our share
capital so that it will consist of the following three classes of shares:



    - Subordinate Voting Shares,



    - Multiple Voting Shares, and



    - Preferred Shares, issuable in series,



each with the rights and attributes described below:



SUBORDINATE VOTING SHARES



    Our holders of Subordinate Voting Shares will be entitled to one vote per
share at any meeting of our shareholders except meetings at which only
shareholders of a specified class of shares (other than the Subordinate Voting
Shares) are entitled to vote. Subject to the preference of any outstanding
Preferred Shares, the holders of Subordinate Voting Shares will be entitled to
participate equally with holders of Multiple Voting Shares in any dividends our
board of directors declares out of funds legally available for the payment of
dividends. If we are liquidated, dissolved or wound up, holders of Subordinate
Voting Shares are entitled to share ratably with holders of Multiple Voting
Shares in all assets remaining after payment of our liabilities and any
liquidation preferences of any outstanding Preferred Shares.



    The Subordinate Voting Shares may not be subdivided, consolidated,
reclassified or otherwise changed unless, at the same time, the Multiple Voting
Shares are subdivided, consolidated, reclassified or otherwise changed equally,
share-for-share, in the same proportion and in the same manner.



MULTIPLE VOTING SHARES



    Holders of Multiple Voting Shares will be entitled to ten votes per share at
any meeting of our shareholders except meetings at which only shareholders of a
specified class of shares (other than the Multiple Voting Shares) are entitled
to vote. Subject to the preference of any outstanding Preferred Shares, the
holders of Multiple Voting Shares are entitled to participate equally with
holders of Subordinate Voting Shares in any dividends our board of directors
declares out of funds legally available for the payment of dividends. If we are
liquidated, dissolved or wound up, holders of Multiple Voting Shares are
entitled to share rateably with holders of Subordinate Voting Shares in all
assets remaining after payment of our liabilities and any liquidation
preferences of any outstanding Preferred Shares. Each Multiple Voting Shares is
convertible at any time, at the option of the holder, into one Subordinate
Voting Share.



    The Multiple Voting Shares may not be subdivided, consolidated, reclassified
or otherwise changed unless, at the same time, the Subordinate Voting Shares are
subdivided, consolidated, reclassified or otherwise changed equally,
share-for-share, in the same proportion and in the same manner.



NEW PREFERRED SHARES ISSUABLE IN SERIES



    On the closing of the offering, our board of directors will be authorized,
without further action by the shareholders, to issue Preferred Shares in one or
more series and to set the number of shares constituting any such series and the
designation, rights, privileges, restrictions and conditions attaching to the
shares of such series including dividend rights and rates, redemption provisions
(including sinking fund provisions), rights of conversion or exchange,
liquidation


                                       76
<PAGE>

preferences and voting rights, if any. The Preferred Shares as a class are
entitled to priority over the Subordinate Voting Shares and Multiple Voting
Shares if our Board of Directors decides to pay any dividends, and, if we are
dissolved, liquidated or wound up, the Preferred Shares are entitled as a class
to priority in respect of return of capital. Except as required by law or the
provisions of any designated series of Preferred Shares, the holders of
Preferred Shares as a class are not entitled to receive notice of, attend or
vote at any meeting of our shareholders.



TAKE-OVER BID PROTECTION



    Under applicable Canadian law, an offer to purchase Multiple Voting Shares
would not necessarily require that an offer be made to purchase Subordinate
Voting Shares. As a result, and to comply with policies adopted by Canadian
securities regulatory authorities and The Toronto Stock Exchange, our holders of
Multiple Voting Shares will enter into a transfer restriction agreement (the
"Transfer Restriction Agreement") with respect to not less than 80% of the
Multiple Voting Shares, effective upon the closing of this offering, with
Montreal Trust Company of Canada, as trustee, and us in order to provide the
holders of Subordinate Voting Shares with particular rights in the event of a
"take-over bid" for Multiple Voting Shares under Canadian law. A "take-over
bid", generally defined, is an offer to acquire outstanding equity or voting
shares of a class, where, upon completion of the offer, the offeror would own
more than 20% of the shares of the class.



    Under the Transfer Restriction Agreement, the parties will agree not to sell
the Multiple Voting Shares owned, directly or indirectly by them or their
affiliates, and which are subject to the Transfer Restriction Agreement, to any
person under circumstances in which (i) the offer or acceptance constitutes a
take-over bid under the Securities Act (Ontario) or the Securities Act (Quebec);
and (ii) securities legislation would have required the same offer to be made to
all holders of Subordinate Voting Shares if the offer had been for Subordinate
Voting Shares rather than Multiple Voting Shares.



    One circumstance where the Securities Act (Ontario) would not require the
same offer to be made to all holders of Subordinate Voting Shares is if:
(i) the purchase is made from not more than five persons; (ii) the bid is not
made generally to holders of the Multiple Voting Shares; and (iii) the price
does not exceed 115% of the market price of the Subordinate Voting Shares.



    The prohibition on sales of Multiple Voting Shares will not apply if an
offer identical in all material respects is made concurrently to purchase
Subordinate Voting Shares, which identical offer has no condition attached other
than the right not to take up and pay for shares tendered if no shares are
purchased pursuant to the offer for Multiple Voting Shares. Under the Transfer
Restriction Agreement, the parties will also agree not to transfer any Multiple
Voting Shares which are subject to the Transfer Restriction Agreement (other
than a transfer to a pledgee, as security or to another party to the Transfer
Restriction Agreement) unless the purchaser is or becomes a party to the
Transfer Restriction Agreement.



SHARE CAPITAL REORGANIZATION



    Our Articles of Continuance currently authorize us to issue an unlimited
number of Class A Non-Voting Shares, an unlimited number of Class B Subordinate
Voting Shares, an unlimited number of Class C Multiple Voting Shares,
100,000,000,000 Series A Non-Voting Preferred Shares, 100,000,000,000 Series B
Subordinate Voting Preferred Shares and 45,000,000 Class C Redeemable Preferred
Shares. Concurrent with the closing of the offering, the following share
conversions and steps to reorganize our capital will occur resulting in the
share capital structure described above:


                                       77
<PAGE>

    - the holders of our existing Class B Subordinate Voting Shares will convert
      or exchange their shares into Class A Non-Voting Shares and all authorized
      but unissued Class B Subordinate Voting Shares will be cancelled,



    - the Series A Non-Voting Preferred Shares will be converted or exchanged
      into our Class A Non-Voting Shares and all of the authorized but unissued
      Series A Non-Voting Preferred Shares, Series B Subordinate Voting
      Preferred Shares and Series C Redeemable Preferred Shares will be
      cancelled,



    - our existing Class A Non-Voting Shares will be redesignated as Subordinate
      Voting Shares and the terms shall be amended to provide the holders with
      one vote per share and otherwise attach those rights and attributes
      described above,



    - our existing Class C Multiple Voting Shares will be amended to provide the
      holders with ten votes per share and the Class C Multiple Voting Shares
      will be redesignated as Multiple Voting Shares, and



    - a class consisting of 500 billion Preferred Shares, issuable in series,
      will be created.



STRATEGIC INVESTORS



    Affiliates of Comcast Corporation, MSD Capital L.P., the private investment
fund for Michael Dell, Liberty Media Corporation, Shaw Communications Inc. and
Oak Investment Partners, Denis O'Brien, Jr., Kleiner Perkins Caufield & Byers,
Dr. Nathan Myhrvold and certain shareholders of GlobeNet, including Boston
Ventures Limited Partnership V, Kelso Investment Associates VI and Providence
Equity Partners III, have purchased or agreed to purchase from Ledcor Limited
Partnership in private transactions an aggregate of 46,956,255 Subordinate
Voting Shares for total cash consideration of approximately $646 million. The
average price per share paid by each of these affiliates was less than the
initial public offering price. The purchasers of these Subordinate Voting Shares
have agreed that they will not transfer their shares for 12 months.


REGISTRATION RIGHTS


    All of our shareholders, with the exception of Worldwide Fiber Holdings
Ltd., Ledcor Limited Partnership and MacKenzie Partners LLC, have demand and
piggyback registration rights. These shareholders own an aggregate of
287,244,777 Subordinate Voting Shares. All of these shareholders have agreed not
to dispose of or hedge any of their Subordinate Voting Shares during the period
from the date of this prospectus continuing through the periods set forth
herein. In addition, all of our shareholders have agreed to waive these
registration rights for at least 12 months. See "Shares Eligible for Future
Sale."

<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE


    Prior to this offering, there has been no market for our Subordinate Voting
Shares. Future sales of substantial amounts of our Subordinate Voting Shares in
the public market could adversely affect prevailing market prices. Sales of
substantial amounts of our Subordinate Voting Shares in the public market after
any restrictions on sale lapse could adversely affect the prevailing market
price of the Subordinate Voting Shares and impair our ability to raise equity
capital in the future.



    Upon completion of the offering, we will have 712,150,465 Subordinate Voting
Shares outstanding and outstanding options to purchase 50,448,100 Subordinate
Voting Shares, assuming no additional option or warrant grants or exercises
after March 17, 2000. None of the 46,000,000 Subordinate Voting Shares sold in
the offering will be subject to the lock-up agreements described below. We
expect that the Subordinate Voting Shares sold in the offering, including any
shares issued upon exercise of the underwriters' over-allotment option, will be
freely tradable without restriction under the Securities Act, unless purchased
by our "affiliates" as that term is defined in Rule 144 under the Securities
Act.



    The remaining 666,150,465 Subordinate Voting Shares outstanding and any
Subordinate Voting Shares subject to outstanding options which are not issued
pursuant to a registration statement are or will be "restricted securities"
within the meaning of Rule 144. Restricted securities may be sold in the public
market only if the sale is registered or if it qualifies for an exemption from
registration, such as under Rule 144, 144(k) or 701 promulgated under the
Securities Act, which are summarized below. Sales of restricted securities in
the public market, or the availability of such shares for sale, could adversely
affect the market price of the Subordinate Voting Shares.


LOCK-UP AGREEMENTS


    Our directors, officers and various other shareholders, who together hold
substantially all of our securities, have entered into lock-up agreements in
connection with this offering. These lock-up agreements generally provide that
the following holders will not offer, sell, contract to sell, grant any option
to purchase or otherwise dispose of our Subordinate Voting Shares or any
securities exercisable for or convertible into our Subordinate Voting Shares
owned by them for the following periods after the date of this prospectus
without the prior written consent of Goldman, Sachs & Co. and Donaldson, Lufkin
& Jenrette Securites Corporation and 360NETWORKS:



    - Ledcor, Worldwide Fiber Holdings Ltd., Madison Square and Mr. Olsen in
      connection with the IRTB shares--18 months;



    - our strategic investors, certain shareholders of GlobeNet (in connection
      with their strategic investment), Mr. Maffei, Mr. Stow, our directors, CN,
      Michels, and the consultant--12 months; and



    - our vice presidents--6 months.



The lock-up agreements cover Subordinate Voting Shares, notwithstanding possible
earlier eligibility for sale under the provisions of Rules 144, 144(k) and 701.


RULE 144

    In general, under Rule 144 as currently in effect, after the expiration of
the lock-up agreements, a person who has beneficially owned restricted
securities for at least one year would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of:


    - one percent of the number of shares of Subordinate Voting Shares then
      outstanding, which will equal approximately 7,121,505 shares immediately
      after this offering; and


                                       79
<PAGE>

    - the average weekly trading volume of our Subordinate Voting Shares during
      the four calendar weeks preceding the sale, which we cannot determine at
      this time.


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

RULE 144(K)

    Under Rule 144(k), a person who is not deemed to have been our affiliate at
any time during the three months preceding a sale, and who has beneficially
owned the shares proposed to be sold for at least two years, may sell these
shares without complying with the manner of sale, public information, volume
limitation or notice requirements of Rule 144.

RULE 701

    Rule 701, as currently in effect, permits our employees, officers, directors
or consultants who purchased shares pursuant to a written compensatory plan or
contract to resell such shares in reliance upon Rule 144, but without compliance
with some restrictions. Rule 701 provides that affiliates may sell their
Rule 701 shares under Rule 144 ninety days after effectiveness without complying
with the holding period requirement and that non-affiliates may sell such shares
in reliance on Rule 144 ninety days after effectiveness without complying with
the holding period, public information, volume limitation or notice requirements
of Rule 144.

REGISTRATION RIGHTS

    We have granted various registration rights to some of our shareholders,
which will enable these shareholders to cause us to register their shares for
sale either in connection with the exercise of a demand registration right or,
subject to particular cutbacks by managing underwriters, "piggyback"
registration rights. For a summary of these rights, please refer to the section
of this prospectus entitled "Share Capital Reorganization and Description of
Capital Stock--Registration Rights."

CANADIAN RESALE RESTRICTIONS


    The Subordinate Voting Shares outstanding immediately prior to the offering
or issued pursuant to the exercise of options granted prior to the offering may
not be sold or otherwise disposed of for value in Canada, except pursuant to
either a prospectus, a discretionary exemption or a statutory exemption
available only in specific limited circumstances, unless or until, among other
things, we have been a reporting issuer for at least twelve months and
disclosure to applicable Canadian securities regulatory authorities has been
made. We intend to apply to applicable Canadian securities regulatory
authorities to permit sales of such shares without the requirement that we be a
reporting issuer for at least twelve months prior to such sales. We will become
a reporting issuer in each of the provinces of Canada upon the filing of this
prospectus with, and the issuance of a receipt therefor by, such Canadian
securities regulatory authorities. In addition, sales of our shares in Canada by
our control shareholders (generally, persons or companies who alone or in
combination with others hold a sufficient number of securities to affect
materially the control of the issuer) will be restricted.

                                   REGULATION

    We do not believe our dark fiber offering is currently subject to extensive
regulation that would have a material adverse effect on our business, financial
condition, or operations. See "Risk Factors--Telecommunications
Regulation--Extensive Regulation." However, we are part of an industry that is
highly regulated by federal, state and local governments whose actions are often
subject to regulatory, judicial, or legislative modification. In addition, to
the extent that any bandwidth capacity and lit fiber offerings are treated as
private carriage, telecommunications services or competitive local exchange
carrier ("CLEC") offerings in the United States, additional federal and state
regulation would apply to those offerings. Accordingly, there can be no
assurance that regulations, current or future, will not have a material adverse
effect on us.

UNITED STATES

    FEDERAL


    U.S. Federal regulation has a significant impact on the telecommunications
industry. Federal regulations have undergone major changes in the last four
years as the result of the enactment of the Telecommunications Act of 1996 (the
"1996 Act") on February 8, 1996. The 1996 Act is the most comprehensive reform
of the U.S. telecommunications law since the Communications Act was enacted in
1934. For example, the 1996 Act imposes a number of interconnection and access
requirements on telecommunications carriers and on all LECs, including incumbent
local exchange carriers ("ILECs") and CLECs.


    The different ways we intend to offer fiber optic supported services could
trigger four alternative types of regulatory requirements:
(1) non-communications services, (2) private carrier services,
(3) telecommunications services or common carriage and (4) CLEC offerings. The
law establishing these alternative regulatory requirements is often unclear, so
it is impossible to predict in many instances how the Federal Communications
Commission ("FCC") will classify our services. Regulations associated with each
type of offering are described below.

    NON-COMMUNICATIONS SERVICES

    The provision of dark fiber can be viewed as a non-communications service in
that it is not a service, but rather the provision of a physical facility that
is indistinguishable from other non-communications offerings such as
constructing an office building. Many providers of dark fiber are currently
operating on the assumption that they are providing unregulated facilities.
Although the FCC attempted to regulate dark fiber as a common carrier service,
this position was vacated by the U.S. Court of Appeals for the District of
Columbia Circuit in 1994. The FCC has not addressed the issue since that time
and, thus, we believe that dark fiber is not regulated as a common carrier
service at this time. However, there is no assurance that the FCC, on remand,
may not take the position again that dark fiber offerings are subject to common
carrier regulation.

    PRIVATE CARRIER SERVICES


    Even if some of our offerings are treated as a communications service, they
could be viewed as a private carrier offering. Private carrier offerings
typically entail the offering of telecommunications, but are provided to a
limited class of users on the basis of individually negotiated terms and
conditions that do not meet the definition of a telecommunications service under
the 1996 Act. If our services are treated as private carriage, they are
generally unregulated by the FCC, but would be subject to universal service
payments based on the gross revenues from end users. See "Regulation--United
States--Federal--Telecommunications Services--Universal Service." Private
carriers may also be subject to access charges if interconnected to LECs.


                                       81

    TELECOMMUNICATIONS SERVICES

    Some of our services, such as the provision of bandwidth capacity and lit
fiber, may be treated as telecommunications services by the FCC. If some of our
services are treated as telecommunications services a significant number of
federal regulatory requirements will be applicable to those services.

    The law essentially defines telecommunications carriers to include entities
offering telecommunications services for a fee directly to the public or to
classes of users so as to be effectively available directly to the public,
regardless of the facilities used. "Telecommunications" is defined as the
transmission, between or among points specified by the user, of information of
the user's choosing, without change in the form or content of the information as
sent and received. For the reasons stated above regarding our belief that we are
not a common carrier, we also believe that we are not a telecommunications
carrier concerning our dark fiber offerings. The FCC has ruled that the term
"telecommunications carrier" is the same as the definition of common carrier
and, therefore, a company providing fiber facilities on an individualized and
selective basis, as we propose, is probably not a telecommunications carrier. A
decision to this effect has been appealed to federal court. A decision on this
appeal reversing or remanding the FCC's conclusion could require that our
services be treated as common carriage. Some railroad, power and
telecommunications associations--none of which are affiliated with us--have
petitioned the FCC to clarify the status of fiber providers in this regard. The
FCC's pending court remand, described above, might also address the application
of these requirements to us. If the FCC decides that these companies are
telecommunications carriers, we would be subject to some regulatory requirements
which may impose substantial administrative and other burdens on us.

    If the FCC finds some of our services to be a telecommunications service, we
may be regulated as a non-dominant common carrier. The FCC imposes regulations
on common carriers such as the Regional Bell Operating Companies ("RBOCs") that
have some degree of market power ("dominant carriers"). The FCC imposes less
regulation on common carriers without market power ("non-dominant carriers").
Under the FCC's rules, we would be a non-dominant carrier and as such do not
need authorization to provide domestic services and can file tariffs on one
day's notice. The FCC requires common carriers to obtain an authorization to
construct and operate telecommunication facilities and to provide or resell
telecommunications services, between the United States and international points.

    GENERAL OBLIGATIONS OF ALL TELECOMMUNICATIONS CARRIERS.  To the extent that
any of our offerings are treated as telecommunications services, we would be
subject to a number of general regulations at the federal level that apply to
all telecommunications carriers, including the obligation not to charge
unreasonable rates or engage in unreasonable practices, the obligation to not
unreasonably discriminate in our service offerings, the need to tariff our
services, the potential obligation to allow resale of our services in certain
circumstances and the fact that third parties may file complaints against us at
the FCC for violations of the Communications Act of 1934 or the FCC's
regulations. Certain statistical reporting requirements may also apply. In
addition, FCC rules require that telecommunications carriers contribute to
universal service support mechanisms, the Telecommunications Relay Service fund,
the number portability fund and the North American Number Plan Administrator
fund.

    INTERCONNECTION OBLIGATIONS OF ALL TELECOMMUNICATIONS CARRIERS.  All
telecommunications carriers have the basic duty to interconnect, either directly
or indirectly, with the facilities of other telecommunications carriers. This is
the minimum level of interconnection required and is generally viewed to impose
only minimal requirements as compared with the interconnection obligations
imposed on incumbent local exchange carriers ("ILECs") and CLECs described in
the next section. All telecommunications carriers must also ensure that they do
not install network features, functions

                                       82
<PAGE>
or capabilities that do not comply with guidelines and standards established by
the FCC to implement requirements to ensure accessibility for individuals with
disabilities and to regulations designed to promote interconnectivity of
networks. These regulations could be burdensome or expensive and could adversely
affect us. The FCC adopted regulations recently that clarify these statutory
requirements.

    If the FCC takes the position that some or all of our fiber offerings are
subject to common carrier regulation, we nonetheless believe that we could
provide facilities in the United States. To do so we would be obligated to
obtain Section 214 authorization to provide fiber between Canada and the United
States and to disclose, among other things, the extent to which we are owned or
controlled by non-U.S. entities. However, FCC policy permits 100 percent direct
or indirect non-U.S. investment in common carriers that do not hold radio
licenses. Thus, we believe that we could obtain Section 214 authority to provide
international common carrier services despite our foreign ownership.
Nevertheless, compliance with these regulatory requirements may impose
additional administrative and other burdens on us that could have a material
adverse effect on our business, financial condition or operations.

    TARIFFS AND PRICING REQUIREMENTS.  In October 1996, the FCC adopted an order
in which it eliminated the requirements that non-dominant interstate
interexchange carriers ("IXCs") maintain tariffs on file with the FCC for
domestic interstate services. The order does not apply to the switched and
special access services of the RBOCs or other LECs. The FCC order was issued
pursuant to authority granted to the FCC in the 1996 Act to "forbear" from
regulating any telecommunications services provider under particular
circumstances. After a nine-month transition period, relationships between
interstate carriers and their customers would be set by contract. At that point,
long distance companies would be prohibited from filing tariffs with the FCC for
interstate, domestic, interexchange services. Carriers have the option to
immediately cease filing tariffs. Several parties filed notices for
reconsideration of the FCC order and other parties have appealed the decision.
On February 13, 1997, the United States Court of Appeals for the District of
Columbia Circuit stayed the implementation of the FCC order pending its review
of the order on its merits. Currently, that stay remains in effect and
interstate long distance telephony companies are therefore still required to
file tariffs. A requirement to file tariffs could lead to regulation of our
offerings at the federal level, although the FCC's regulation of non-dominant
carriers' tariff filings has been minimal to date. Competitive access providers
do not have to file tariffs for their exchange access services, but may if they
choose to do so.

    If the stay is lifted and the FCC order becomes effective,
telecommunications carriers will no longer be able to rely on the filing of
tariffs with the FCC as a means of providing notice to customers of prices,
terms and conditions on which they offer their interstate services. The FCC has
required that non-dominant IXCs post their rates, terms and conditions for all
their interstate, domestic services on their Internet web sites if they have
one; this rule is effective once its mandatory detariffing order takes effect.
The obligation to provide non-discriminatory, just and reasonable prices remains
unchanged under the Communications Act of 1934. Tariffs also allow a carrier to
limit its liability to its customers, including in connection with service
interruptions. If tariffs are eliminated, we may become subject to liability
risks that we would have been able to limit through tariff filings, and there
can be no assurance that potential liabilities will not have a material adverse
effect on our results of operations and financial condition and ability to meet
our obligations under the notes. In addition, we must obtain prior FCC
authorization for installation and operation of international facilities and the
provision (including resale) of international long distance services. We are
considering whether to file tariffs for these services and would have to file
tariffs to the extent our international services are treated as
telecommunications services. There has been no proposal to detariff
international services.

                                       83
<PAGE>
    With limited exceptions, the current policy of the FCC for most interstate
access services dictates that ILECs charge all customers the same price for the
same service. Thus, the ILECs generally cannot lower prices to some customers
without also lowering charges for the same service to all similarly situated
customers in the same geographic area, including those whose telecommunications
requirements would not justify the use of the lower prices. The FCC in 1999,
however, modified this constraint on the ILECs when they face specified levels
of competition, which permits them to offer special rate packages to some
customers, as it has done in few cases, and other forms of rate flexibility. The
rules contemplate an increasing level of flexibility on a city-by-city basis as
competitors have facilities in place to compete for local exchange services in
those markets. Once such facilities attain 50% coverage the rules contemplate
only minimal regulation of carrier access offerings.

    CUSTOMER PROPRIETARY NETWORK INFORMATION.  In February 1998, the FCC adopted
rules implementing Section 222 of the Communications Act of 1934, which governs
the use of customer proprietary network information by telecommunications
carriers. Customer proprietary network information generally includes any
information regarding a subscriber's use of a telecommunications service, where
it is obtained by a carrier solely by virtue of the carrier-customer
relationship. Customer proprietary network information does not include a
subscriber's name, telephone number and address, if that information is
published or accepted for publication in any directory format. Under the FCC's
rules, a carrier may only use a customer's proprietary network information to
market a service that is "necessary to, or used in," the provision of a service
that the carrier already provides to the customer, unless it receives the
customer's prior oral or written consent to use that information to market other
services. The Court of Appeals for the Tenth Circuit recently invalidated the
FCC's rules with respect to how a carrier must obtain customer authorization for
the use of customer proprietary network information. The FCC is expected to
further challenge this court decision. In addition, the FCC recently relaxed a
number of the requirements it originally adopted, which gives some flexibility
to carriers on how to comply with these rules. These rules, either as adopted or
as modified, may impede our ability to effectively market integrated packages of
services and to expand existing customers' use of our services.

    UNIVERSAL SERVICE.  On May 8, 1997, the FCC released an order establishing a
significantly expanded federal universal service subsidy regime. For example,
the FCC established new subsidies for telecommunications and certain information
services provided to qualifying schools and libraries and for services provided
to rural health care providers. The FCC also expanded or revised the federal
subsidies for local exchange telephony services provided to low-income consumers
and consumers in high-cost areas. Providers of interstate telecommunications
services, as well as certain other entities, such as private carriers offering
excess capacity to end user customers, must pay for these programs. Our share of
these federal subsidy funds would be calculated based on end-user revenues. The
schools and libraries and rural health care support mechanisms are assessed
against interstate, international and intrastate end-user revenues. Currently,
the FCC is calculating assessments based on the prior year's revenues and has
recently increased the size of the schools and libraries fund by 50 percent.
Assuming that the FCC continues to calculate contributions based on the prior
year's revenues, we believe that we will not be liable for subsidy payments in
any material amount during 2000 because we had no significant end user revenues
in 1999. With respect to subsequent years, however, we are currently unable to
quantify the amount of subsidy payments that we will be required to make or the
effect that these required payments will have on our financial condition. In the
May 8th order, the FCC also announced that it would revise its rules for
subsidizing service provided to consumers in high-cost areas. The FCC has
recently adopted the cost model which it will use to determine the subsidies
needed for high-cost areas. The FCC also established the mechanism which will be
used starting January 1, 2000 to determine the level of high cost support
non-rural carriers will receive. This decision is expected to increase the fund
by only a modest amount. In addition, the Court of

                                       84
<PAGE>
Appeals for the Fifth Circuit recently affirmed the FCC's universal service
program in large part, except that contributions must be based entirely on
interstate and international services of interstate carriers (except for
carriers providing predominately international services). This decision could
substantially affect the level of contributions depending on the jurisdictional
nature of the services provided by a carrier. Several petitions for
administrative reconsideration of the original FCC order are pending.

    CALEA.  We might incur significant expenses to assure that our networks
comply with the requirements of CALEA. Under CALEA, telecommunications carriers
are required to: (1) provide law enforcement officials with call content and
call identifying information pursuant to a valid electronic surveillance warrant
("assistance capability requirements") and (2) reserve a sufficient number of
circuits for use by law enforcement officials in executing court authorized
electronic surveillance ("capability requirements"). To the extent that we
provide facilities-based services, we may incur costs in meeting both of these
requirements. In particular, regarding the assistance capability requirements,
the government is only required to compensate carriers for the costs of making
equipment installed or deployed before January 1, 1995 CALEA complaint. While
the telecommunications industry is attempting to negotiate legislative and
administrative changes to this reimbursement cut-off date, as it stands today,
we will be financially responsible for ensuring that our post-1995 equipment is
in compliance. Regarding the capacity requirements, the government will finance
any necessary increases in capacity for equipment installed or deployed prior to
September 8, 1998, and we are responsible for paying for any necessary increases
in capacity for equipment installed or deployed after that date.

    WIRING IN MULTI-TENANT BUILDINGS.  The FCC recently instituted a proceeding
that could impose obligations on telecommunication carriers' obligation to
provide access to competitors or customers to their wiring located in
multi-tenant residential and business buildings. It is unknown at this time how
the FCC will rule in this proceeding so it is impossible to evaluate its impact
on our operations.

COMPETITIVE LOCAL EXCHANGE CARRIERS OFFERINGS


    It is unclear whether we would be viewed as a CLEC with respect to the
provision of some of our services. A CLEC is defined as a provider of telephone
exchange service, which is an interconnected service of the character ordinarily
furnished by a single exchange, covered by the local exchange charge, or
comparable service provided through a system of switches, transmission
equipment, or other facilities, or combination thereof, by which a subscriber
can originate and terminate a telecommunications service. The full parameters of
what carriers are classified as a CLEC have never been fully defined by the FCC.
We do not intend to operate as a CLEC. However, the FCC may disagree with this
position. If we are classified as a CLEC, obligations described below that are
applicable to CLECs would apply.


    INTERCONNECTION OBLIGATIONS.  The 1996 Act is intended to increase
competition. The act opens the local services market by requiring ILECs and
CLECs, including us to the extent we are treated as a common carrier providing
local exchange service, to permit interconnection to their networks and
establishing obligations with respect to:

        RECIPROCAL COMPENSATION.  Requires all ILECs and CLECs to complete calls
    originated by competing carriers under reciprocal arrangements. The prices
    charged by ILECs for terminating calls originated on a CLEC's network must
    be based on a reasonable approximation of additional cost or through mutual
    exchange of traffic without explicit payment.

        RESALE.  Requires all ILECs and CLECs to permit resale of their
    telecommunications services without unreasonable restrictions or conditions.
    In addition, ILECs are required to offer

                                       85
<PAGE>
    all retail telecommunications services to other carriers for resale at
    discounted rates, based on the costs avoided by the ILEC in the offering.

        INTERCONNECTION.  Requires all ILECs and CLECs to permit their
    competitors to interconnect with their facilities. Requires all ILECs to
    permit interconnection at any technically feasible point within their
    networks, on nondiscriminatory terms, at prices based on cost (which may
    include a reasonable profit). At the option of the carrier seeking
    interconnection, collocation of the requesting carrier's equipment on the
    ILEC's premises must be offered, except where an ILEC can demonstrate space
    limitations or other technical impediments to collocation.

        UNBUNDLED ACCESS.  Requires all ILECs to provide nondiscriminatory
    access to unbundled network elements (including network facilities,
    features, functions and capabilities) at any technically feasible point
    within their networks, on nondiscriminatory terms, at prices based on cost
    (which may include a reasonable profit). In response to the Supreme Court's
    decision in AT&T V. IOWA UTILITIES BOARD that required the FCC to reconsider
    which elements should be unbundled, the FCC has adopted an order on remand
    that affirms its original decision in all significant respects.

        NUMBER PORTABILITY.  Requires all ILECs and CLECs to permit users of
    telecommunications services to retain existing telephone numbers without
    impairment of quality, reliability or convenience when switching from one
    LEC to another.

        DIALING PARITY.  Requires all ILECs and CLECs to provide
    nondiscriminatory access to telephone numbers, operator services, directory
    assistance and directory listing with no unreasonable dialing delays. They
    must also provide dialing parity for inter-local access and transport area
    ("LATA") services and for intra-LATA toll services. LECs are required to
    implement dialing parity for intra-LATA toll services during 1999.

        ACCESS TO ROW.  Requires all ILECs and CLECs to permit competing
    carriers access to poles, ducts, conduits and ROW at reasonable and
    nondiscriminatory rates, terms and conditions.

    ILECs are required to negotiate in good faith with carriers requesting any
or all of the above arrangements. If the negotiating carriers cannot reach
agreement within a prescribed time, either carrier may request binding
arbitration of the disputed issues by the state regulatory commission. Where an
agreement has not been reached, ILECs remain subject to interconnection
obligations established by the FCC and state telecommunication regulatory
commissions.

    In August 1996, the FCC released a decision (the "Interconnection Decision")
establishing rules implementing the 1996 Act requirements that ILECs negotiate
interconnection agreements and providing guidelines for review of these
agreements by state public utilities commissions. On July 18, 1997, the Eighth
Circuit vacated particular portions of the Interconnection Decision, including
provisions establishing a pricing methodology and a procedure permitting new
entrants to "pick and choose" among various provisions of existing
interconnection agreements between ILECs and their competitors. On October 14,
1997, the Eighth Circuit issued a decision vacating additional FCC rules. The
Supreme Court has reversed the Eighth Circuit's decision on the pricing and
"pick and choose" rules. The Eighth Circuit recently issued its mandate to
implement the Supreme Court's decision and established procedures for deciding
the remaining issues on appeal that were not addressed by the Eighth Circuit or
the Supreme Court. These regulations impose added obligations on potential
competitors of the company that we would not have to comply with if we were not
classified as a CLEC. To the extent that the FCC changes these regulations to be
less burdensome, we could face added competition from these companies in the
provision of our own services that could adversely affect us. To the extent that
carriers may obtain low-priced

                                       86
<PAGE>
access to CLEC and ILEC networks, this could reduce the demand for our fiber
services. Changes to these interconnection obligations that reduce the
interconnection obligations of our competitors could also adversely affect our
business.

    In addition, the FCC has the responsibility under the 1996 Act to determine
what elements of an ILEC's network must be provided to competitors on an
unbundled basis. In August 1999, the FCC required fiber to be offered as an
unbundled element. In addition, the FCC had previously allowed state commissions
to establish additional unbundling requirements, and some states have required
that ILECs unbundle fiber. These decisions to unbundle fiber may decrease the
demand for our offerings.

    OTHER FEDERAL COMMUNICATIONS REQUIREMENTS.  CLECs are also subject to other
FCC filing requirements. Compliance with these obligations, individually and in
the aggregate, may cause us to incur substantial expenses. There can be no
assurance that these expenses will not have a material adverse effect upon our
results of operations and financial condition and our ability to meet our
obligations under the notes. CLECs may, but are not required to, file tariffs
for their interstate access services and these rates are regulated as previously
described for non-dominant carriers. See "Regulation--United
States--Federal--Telecommunications Services--Tariffs and Pricing Requirements."
However, the FCC recently issued a Notice of Proposed Rulemaking asking whether
it should regulate the terminating access changes of such providers.

    To the extent we provide interexchange telecommunications service, we are
required to pay access charges to ILECs when we use the facilities of those
companies to originate or terminate interexchange calls. The interstate access
charges of ILECs are subject to extensive regulation by the FCC, while those of
CLECs or non-CLECs are subject to a lesser degree of FCC regulation but remain
subject to the requirement that all charges be just, reasonable and not
unreasonably discriminatory. With limited exceptions, the current policy of the
FCC for most interstate access services dictates that ILECs charge all customers
the same price for the same service. Thus, the ILECs generally cannot lower
prices to some customers without also lowering charges for the same service to
all similarly situated customers in the same geographic area. The FCC recently,
however, modified this constraint on the ILECs when specified levels of
competition from local exchange providers occur and permitted them to offer
special rate packages to some customers, as it has done in a few cases,
permitted other forms of rate flexibility. The rules contemplate an increasing
level of flexibility on a city-by-city basis as competitors have facilities in
place to compete for local exchange services in those markets. Once such
facilities attain 50% coverage the rules contemplate only minimal regulation of
carrier access offerings. In two orders released on December 24, 1996 and
May 16, 1997, the FCC made major changes in the interstate access charge
structure. The FCC removed restrictions on ILECs' ability to lower access
charges and relaxed the regulation of new switched access services in those
markets where there are other providers of access services. The May 16th order
increased the costs that price cap LECs recover through monthly, non-traffic
sensitive access charges and decreased reliance on traffic-sensitive charges. In
the May 16th order, the FCC also announced its plan to bring interstate access
rate levels more in line with cost. The plan will include rules that may grant
price cap LECs increased pricing flexibility if the ILEC demonstrates that it
faces increased competition (or potential competition) in relevant markets. The
manner in which the FCC implements this approach to lowering access charge
levels could have a material adverse effect on our ability to compete in
providing interstate access services. On appeal, the court upheld the FCC's
May 16th order in a decision issued on August 19, 1998.

    Under the 1996 Act, RBOCs are currently prohibited from providing inter-LATA
telecommunication services until they can demonstrate that they have opened
their local markets to competition. Bell Atlantic in New York received such
approval in December 1999. RBOCs are reported to have made substantial progress
in achieving compliance with the requirements for such approvals and one or more
RBOCs may receive inter-LATA approval in some states within the next

                                       87
<PAGE>
year. In anticipation of receiving inter-LATA approval, some RBOCs have made
investment in fiber providers that compete with us, e.g., Qwest and Williams. If
regulators grant widespread inter-LATA approvals, we could be adversely affected
through added competition because of these regulatory approvals.

    RECIPROCAL COMPENSATION.  All ILECs and CLECs must complete calls originated
by other carriers under reciprocal compensation arrangements. That is, the LEC
terminating a local call is entitled to payment from the LEC originating a call.
Charges assessed by the ILECs for terminating calls originated on a CLEC's
network must be based on a reasonable approximation of additional cost or
through mutual exchange of traffic without explicit payment. The FCC determined
that Internet traffic is interstate in nature, not local, and has initiated a
proceeding to determine appropriate carrier-to-carrier compensation. At the same
time, the FCC declined to overturn a multitude of state decisions requiring
ILECs to pay CLECs compensation for delivering Internet traffic to ISPs. The
FCC's decision is on appeal, and ILECs are expected to ask states or federal
courts to reverse the existing state determinations.

REGULATION OF CABLE

    The FCC has the responsibility under the Act Relating to the Landing and
Operation of Submarine Cables in the United States, 47 U.S.C.
SectionSection34-39 ("Cable Landing Act"), to issue licenses for the landing and
operation of submarine cables in the United States. The FCC routinely grants
cable landing licenses to applicants, similar to us, from WTO Member countries
subject to U.S. State Department approval. However, applicants must disclose the
extent to which they are owned or controlled by non-U.S. entities. Although the
FCC retains the right to restrict foreign ownership of cable landing licenses
that raise national security concerns, it has not yet done so. We already hold
one submarine cable landing license and believe that the FCC is unlikely to
restrict our ownership of additional cable landing licenses despite our foreign
ownership. Nevertheless, there can be no assurance that the FCC would not deny,
or condition, any application by us to provide common carrier services. No later
than 90 days prior to construction of the cable, however, applicants for cable
landing licenses must also provide ownership information with respect to the
cable landing station. The FCC may restrict non-U.S. ownership of cable landing
stations to protect the national security of the United States. The construction
of new submarine cable systems is categorically excluded from environmental
processing rules.

    STATE

    The 1996 Act prohibits state and local governments from enforcing any law,
rule or legal requirement that prohibits or has the effect of prohibiting any
entity from providing any interstate or intrastate telecommunications service.
In addition, under current FCC policies, any dedicated transmission service or
facility that is used more than 10% of the time for interstate or foreign
communication is generally subject to FCC jurisdiction rather than state
regulation.

    Despite these prohibitions and limitations, telecommunications services are
subject to various state regulations. Among other things, the states may:

    - require the certification of TSPs,

    - regulate the rates of intrastate offerings and the terms and conditions of
      both intrastate and certain interstate service offerings and

    - adopt regulations necessary to preserve universal service, ensure the
      continued quality of communications services, safeguard the rights of
      consumers and protect public safety and welfare. Accordingly, state
      involvement in telecommunications services may be substantial.

                                       88
<PAGE>
    In addition, state law may not recognize "private carriage" and, therefore,
even if certain of our offerings are treated as "private carriage" at the
federal level, they may be regulated as telecommunications or common carrier
services at the state level. At present, we, through various subsidiaries, have
tariffs on file with, and/or have obtained various certificates of operating
authority from, approximately 25 states that were necessary under state laws to
gain authorizations needed to operate as a carrier or to construct fiber
facilities in those states, even though we do not operate as a common carrier.
Those tariffs provide that prices, terms and conditions of an offering will be
set based upon individual determinations for each customer. These tariffs may be
subject to challenge, but usually are not challenged. None of our tariffs has
been changed to date. Various state regulators may attempt to regulate our rates
or practices, but, generally, state regulators do not actively regulate the
offerings of non-dominant carriers such as us.

    The state regulatory environment varies substantially from state to state.
For example, our pricing flexibility for products or services which are
intrastate in nature may be limited by regulation in some jurisdictions. In
addition, in arbitrating interconnection agreements under the 1996 Act between
ILECs and their potential competitors, some state commissions have considered
whether fiber should be an unbundled network element. The New York Public
Service Commission determined that it would not require NYNEX Corporation to
provide fiber as an unbundled network element. State commissions in Florida,
Maryland, North Carolina and Virginia have either refused to require the ILECs
to offer fiber to competitors or have stated that the issue would be addressed
at a later time. On the other hand, state commissions in Illinois,
Massachusetts, Arizona, Georgia, Minnesota, Ohio, Oregon and Tennessee have
found fiber to be a network element and required the ILECs to offer it on an
unbundled basis to CLECs. There can be no assurance that these requirements, and
the associated pricing methodologies, where applicable will not reduce the
demand for our offerings.

    LOCAL

    In addition to federal and state laws, local governments exercise legal
authority that may affect our business. For example, some local governments
retain the ability to license public ROW, subject, however, to the federal
limitation that local authorities may not prohibit entities from entering the
telecommunications market. Compliance with local requirements may delay and
increase the costs of our use of public ROW. Accordingly, these requirements
could impose substantial burdens on us.

CANADA


    We offer bandwidth services to our customers in Canada through resale
arrangements. Under these resale arrangements, we obtain the use of transmission
facilities on a non-exclusive, contractual basis from Urbanlink and then offer
bandwidth services to our customers through the subsequent sale or lease, on a
commercial basis, of these contracted facilities. As a reseller, we are not
generally subject to the regulatory requirements of the Telecommunications Act
(Canada). However, there can be no assurance that the regulation of resellers in
Canada may not become more extensive in the future. In addition, while we
believe that our operations as a reseller in Canada fully comply with Canadian
law, there can be no assurance that a future determination of the Canadian
Radio-television and Telecommunications Commission or events beyond our control
will not result in a change in our status or affect our ability to offer
services in Canada.



    The CRTC is considering reform of the current contribution regime. The
CRTC's contribution regime was originally established in 1992 as a means of
ensuring that rates for local residential telephone service remain affordable.
Under the regime, providers of certain types of long distance voice and data
services are required to pay a subsidy or "contribution" on each minute of
traffic that is originated or terminated on local switched telephone networks or
on cross-border or


                                       89
<PAGE>

overseas access circuits. These contribution payments are pooled within each
ILEC territory and are paid out to ILECs and CLECs serving residential local
customers, based on the number of residential network access services they serve
and the level of the subsidy available in the rate band being served. On
March 1, 1999, the CRTC initiated a proceeding to consider possible reforms to
the current contribution mechanism. In the public notice that initiated the
proceeding, the CRTC invited interested parties to submit proposals on other
mechanisms which could be used to collect contribution. Although this public
notice proceeding is not yet closed, some parties in the proceeding have
advocated that the current contribution regime should be converted into a
revenue-based regime under which contribution would be paid on a percentage of a
TSP's revenues (regardless of the types of services offered by the service
provider), rather than on certain types of telecommunications traffic.



    We do not believe that the majority of our activities in Canada are subject
to the requirement to pay contribution under the current contribution regime.
However, given that the current contribution regime is under review by the CRTC,
there can be no assurance that we would be exempt from the requirement to pay
contribution in the future, particularly if the CRTC decides to adopt a revenue-
based regime.


    RESTRICTIONS ON FOREIGN OWNERSHIP

    Under the Canadian ownership provisions of the Telecommunications Act,a
"telecommunications common carrier" is not eligible to operate in Canada unless
it is owned and controlled by Canadians. Furthermore, no more than 20% of the
members of the board of directors of a telecommunications common carrier may be
non-Canadian and no more than 20% of the voting shares of a telecommunications
common carrier may be beneficially owned by non-Canadians. In addition, no more
than 33 1/3% of the voting shares of a non-operating parent corporation of a
telecommunications common carrier may be beneficially owned or controlled by
non-Canadians and neither the telecommunications common carrier nor its parent
may be otherwise controlled in fact by non-Canadians.


    Although we believe that our activities in Canada, including the Canadian
telecommunications arrangement, comply with the foreign ownership provisions of
the Telecommunications Act, there can be no assurance that a future Canadian
Radio-television and Telecommunications Commission determination or events
beyond our control will not result in our being required to comply with the
ownership provisions of the Telecommunications Act.


    INTERNATIONAL TRAFFIC


    On October 1, 1998, the CRTC issued Telecom Decision CRTC 98-17 ("Decision
98-17") which established a framework for competition in Canada's international
telecommunications services market to coincide with the Government of Canada's
decision to terminate the monopoly of Teleglobe Canada Inc. over
telecommunications facilities linking Canada to overseas destinations. In that
decision, the CRTC determined that a party acquiring an IRU interest in an
international submarine cable would not necessarily fall within the definition
of a TCC. As a result, acquirers of IRUs in international submarine cables need
not be Canadian-owned and controlled. We believe that this determination by the
CRTC will create greater opportunities for foreign owned TSPs to purchase IRUs
and other types of wholesale bandwidth capacity in the Canadian portion of our
network. However, given the fact that the CRTC's findings in Decision 98-17 were
limited to IRU interests held in international submarine cables, as well as the
fact that IRU arrangements can involve various degrees of ownership and control
over fiber facilities, there can be no assurance that holders of IRUs acquired
in domestic fiber facilities, including those obtained by us from Urbanlink,
would be exempt from the Canadian ownership provisions contained in the
Telecommunications Act.


                                       90
<PAGE>

    In addition to determining the status of IRUs under the Telecommunications
Act, the CRTC made a determination in Decision 98-17 to eliminate Canada's
"bypass" rules, which had prohibited the routing of Canada-Canada and
Canada-overseas traffic through the United States. Effective October 1, 1998,
TSPs and users in Canada may route basic telecommunications traffic which either
originates or terminates in Canada through the United States. Given the fact
that a decision to bypass Canadian network facilities may be based on a variety
of factors, including, but not limited to, cost, technology, traffic patterns
and the availability of suitable facilities, there is a risk that prospective
customers for our bandwidth services in Canada may choose to purchase, lease or
obtain IRUs in dark or lit fiber in the United States rather than in Canada.
There can be no assurance that we will be able to attract and retain a
sufficient number of customers for the Canadian portions of our bandwidth
services in Canada, which could have a material adverse effect on our business,
financial condition and results of operations.


    On September 18, 1998, the Stentor alliance announced that, while it will
continue to coordinate national network management for the regionally based
ILECs, it will cease other joint initiatives in national product development,
marketing and other areas. We believe that the restructuring of the Stentor
alliance, the launch by Bell Canada of its national telecommunications company,
the merger of BC TELECOM Inc. and TELUS to create BCT.Telus and the merger of
ILECs in Atlantic Canada to create Aliant will create increased opportunities
for us in the Canadian carrier market as the ILECs expand beyond their
traditional serving territories.

    CRTC PROCEEDINGS


    On March 19, 1999, Urbanlink's predecessor filed an application with the
Canadian Radio-television and Telecommunications Commission seeking orders under
the Telecommunications Act which would permit Urbanlink's predecessor to
continue to have access to street crossings and other municipal properties in
the City of Vancouver for the purpose of constructing, testing and operating
Urbanlink's network facilities within that city. In an answer to that
application, the City of Vancouver took the position that Urbanlink's
predecessor was not eligible to apply to the Canadian Radio-television and
Telecommunications Commission for relief under the Telecommunications Act. On
the same day, the City filed an application with the Canadian Radio-television
and Telecommunications Commission requesting orders which would permit some of
the carriers that have obtained indefeasible rights of use from Urbanlink's
predecessor to continue to construct, operate and maintain those facilities on a
zero rate, interim basis until the Canadian Radio-television and
Telecommunications Commission has made a determination on the appropriate terms,
conditions and compensation that should be payable to the City for the use of
municipal property. In a ruling issued on October 27, 1999, the Canadian
Radio-television and Telecommunications Commission granted the City's request
for an interim order directing each of the carriers that obtained indefeasible
rights of use from Urbanlink's predecessor to pay the City $1.00 for the right
to access the City's municipal property during the period of time before the
Canadian Radio-television and Telecommunications Commission makes a
determination for the appropriate terms, conditions and compensation that should
be payable to the City for the use of municipal property. On December 3, 1999,
the Canadian Radio-television and Telecommunications Commission issued a public
notice which invited interested parties to comment on what the terms and
conditions of access by Canadian carriers to municipal property in Vancouver
should be for the purposes of constructing, maintaining and operating
transmission lines. We anticipate that the Canadian Radio-television and
Telecommunications Commission will render a decision on the March 19, 1999
application of Urbanlink's predecessor against the City at the same time that it
renders a decision on the matters raised by its public notice proceeding.
Failure to obtain the orders requested by Urbanlink's predecessor in its initial
application to the Canadian Radio-television and Telecommunications Commission
could result in increased costs to us which could have a material adverse effect
on our business, financial condition and results of operations.


                                       91
<PAGE>

    In a related matter, the City of Vancouver has served Telus, a conduit
provider to Urbanlink, with notices to terminate, effective December 31, 2000,
most existing agreements between Telus and the City for access to street
crossings and other municipal property. The City has stated that this will allow
an opportunity for meaningful negotiation based on the terms and conditions that
the Canadian Radio-television and Telecommunications Commission ultimately
prescribes for access to municipal property. We currently have IRUs in Urbanlink
facilities that are placed in the Telus conduit in the City of Vancouver. The
results of any such negotiations could lead to increased maintenance and
operation charges to us by Urbanlink. If our continued access to this conduit is
jeopardized, our ability to operate our Vancouver network may be impaired and
our business could be adversely affected.


EUROPEAN UNION

    Regulations of telecommunications in the European Union (Austria, Belgium,
Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, The
Netherlands, Portugal, Spain, Sweden and the United Kingdom) is subject to the
requirements of European Union Law. Apart from general antitrust rules, the
relevant European Union law mainly consists of directives adopted by the
European Council and the European Commission (pursuant to the Treaty of Rome),
which are addressed to, and are binding on, the member states of the European
Union, and which require implementation in the national laws of those states.
These directives are intended to establish harmonized core regulatory
requirements across the European Union. They do not, however, cover every aspect
of telecommunications regulation. In addition, in some cases they give a choice
of different options to the member countries, or are limited to giving general
principles, the detailed implementation of which must be established by the
relevant national legislation.

    European Union law requires that many of the rules concerning licensing,
interconnection, retail service and technical issues should have substantially
the same effect in all member countries. However, due to the permitted
discretion as to how EU rules are given effect within national boundaries,
and/or due to ambiguity in the EU rules giving rise to different interpretations
and/or due to failure by member states to properly implement such rules by the
required deadline or correctly, there are often important differences in the
applicable rules between member states. Private parties may, in reliance on
European Union Directives, be able to bring actions in their national courts
against national laws or regulations which fail to properly implement EU
Directives but legal proceedings are costly and take a long time. The European
Commission may bring actions in the European Court of Justice against the member
states for failure to implement EU legislation properly, but such action may
also take a long time, and the European Commission does not always take such
action or only takes such action after a considerable delay. In consequence, for
practical purposes, there may be significant differences between the rules
applying in different member states, even where European Law is intended to
introduce rules which are similar in effect.


    A Commission Directive known as the Full Competition Directive required all
member states except those with express derogations (Greece, Ireland,
Luxembourg, Portugal and Spain) to permit competition in all telecommunications
services by removing restrictions on the provision of telecommunications
services and telecommunications infrastructure by January 1, 1998.


    A directive known as the Licensing Directive establishes a framework for the
granting of national authorizations and licenses "for the purpose of providing
telecommunications services, including authorizations for the establishment
and/or operation of telecommunications networks required for the provision of
such services." We are advised that there is substantial support for the view
that this directive, and/or other directives only enable member states to
require telecommunications licenses, authorizations, or other forms of
permission, to the extent that a telecommunications service is being provided
and that absent such service, as in the case of the

                                       92
<PAGE>
mere construction or control of or provision of unlit optical fiber cables, no
telecommunications license, authorization or other permission can be required
under European Union law. However we are also advised not all member states may
interpret the requirements of European Union law in this manner, and that for
practical purposes it is therefore necessary to analyze national law and
regulation in each case. When we are operating or in control of fiber which is
functioning or "lit" we are advised that we may on the other hand, in any
particular member state, be required, to apply for an individual license if we
are deemed to be providing a public telecommunications network or publicly
available voice telephony services, or that we may benefit from applying for
such a license to gain the rights to numbers and to gain access to ROW in
respect of land. Alternatively, in some countries, we may simply be required to
comply with a notification or registration procedures.

    A directive known as the Interconnection Directive requires that in any
member state where we eventually offer leased lines to user premises, or control
access to network termination points identified by numbers in the national
numbering plan, we will have the right to negotiate interconnection with any
other operators and the obligation to negotiate such interconnection when so
requested. In addition, to the extent that we offer "bearer capabilities,"
individual member states may give us the right (and, if so, the obligation) to
negotiate interconnection with other operators.

    The Interconnection Directive also requires that to the extent that we are
included by any member state in the class of operators with a right and
obligation to interconnect as just described, then fixed network operators
deemed by the member state regulator, to have "significant market power" (as
defined in that directive) must offer us interconnection on standard, cost
oriented, non-discriminatory and transparent terms. However, to the extent that
we are not granted any interconnection rights in any member state, we will not
be entitled to cost-oriented charges from such an operator, and may be required
to pay tariffs which are significantly higher in most member states.

    The European Commission has recommended that cost-oriented interconnection
charges which some fixed network operators with significant market power are
required to apply, should be based on long run incremental costs, which is
similar to TELRIC, the cost model used by the FCC in the US. However, in the
absence of appropriate accounts or models of such rates, the Commission has
published benchmark interconnection rates, above which national regulators
should seek justification from the relevant fixed network operator.

    Each European Union member state in which we currently conduct our business
has a different regulatory regime and such differences are expected to continue.
In addition, in connection with the Telia agreement we will be operating a
segment of our European network in Norway, which is not a member of the European
Union and therefore not subject to the various rules and regulations governing
European Union member states. Norway does however have its own regulatory regime
to which our operations will be subject.


360AMERICAS



    Our planned 360AMERICAS undersea fiber optic cable facilities and
telecommunications services, including backhaul services, may be subject to
regulation in each jurisdiction where the 360AMERICAS cable and the BUS-1
undersea fiber optic cable system that connects Bermuda and the United States
("BUS-1") land. GlobeNet currently has in place all of the necessary licenses to
land and provide services from the BUS-1 system. In order to implement fully the
360AMERICAS cable, it may be necessary for GlobeNet to obtain authority to land
the cable and to offer telecommunications services, including backhaul, to our
customers in each jurisdiction in which the cable lands. See "Risk
Factors--Government Regulation."


                                       93
<PAGE>

UNITED STATES



    In the United States, the laws and regulations pertaining to undersea cable
systems and telecommunications services are well developed and an established
set of rules and procedures exist. GlobeNet has reviewed with Alcatel our
various options with respect to the most optimal landing locations. On June 2,
1999, GlobeNet submitted a cable landing license application to the FCC seeking
authority to land and operate the 360AMERICAS cable in Tuckerton, New Jersey
(next to the landing stations for the BUS-1 system) and Boca Raton, Florida. On
December 10, 1999, the FCC granted TeleBermuda International Limited ("TBI"), a
wholly owned subsidiary of GlobeNet, a landing license for the 360AMERICAS
cable.



    TBI's U.S. affiliate, TeleBermuda International L.L.C. ("TBI L.L.C."), was
formed in May 1996 as a limited liability company under the laws of the State of
Delaware. TBI L.L.C. holds the landing license for the BUS-1 system in the
United States issued by the FCC, as well as certain ownership and leasehold
rights with respect to BUS-1 system assets located in the United States. TBI
L.L.C. is a wholly owned subsidiary of TBI. Previously, TBI held a 20% ownership
interest in TBI L.L.C., and Elbac Cable Corporation ("Elbac") held the remaining
80% ownership interest. On October 29, 1999, the FCC issued a Memorandum Opinion
and Order granting authority for TBI to acquire Elbac, including the 80%
ownership interest held by Elbac in TBI L.L.C. This transaction was consummated
on November 1, 1999, thus providing TBI with a 100% ownership interest in TBI
L.L.C.



    TBI is authorized to operate in the United States as a common carrier
pursuant to Section 214 of the Communications Act of 1934, as amended. This
allows TBI to provide any telecommunications services, including backhaul
services, to or from the United States via any means, including our current and
future undersea fiber optic cable systems.



BRAZIL AND VENEZUELA



    In countries such as Brazil and Venezuela with recently privatized
telecommunications industries, many of the telecommunications laws and
regulations are relatively new and still evolving. In both of these countries,
there are no current statutes or regulations regarding the landing of undersea
fiber optic cable facilities. Accordingly, authorities have been consulted with
the appropriate regulatory authorities in Brazil (ANATEL) and Venezuela
(CONATEL). Based on these consultations, GlobeNet believes that it is the first
private undersea fiber optic cable operator to request governmental approval to
land an international fiber optic cable system in either jurisdiction. These
consultations have indicated to GlobeNet that the procompetitive effects of
deregulation and the desire to attract foreign investment have created flexible
regulatory environments in Brazil and Venezuela that are receptive to projects
such as the 360AMERICAS cable.



    The need for new undersea fiber optic cable systems is particularly strong
in these countries where former monopoly providers previously controlled access
to and from the country through their ownership of international capacity on
traditional consortium cable systems. Although competition in the provision of
telecommunications services has begun to be introduced in both jurisdictions,
the former monopoly carriers continue to control the existing inventory of
available undersea fiber optic capacity that lands in each country. Accordingly,
capacity remains scarce and very expensive.



BRAZIL





    On March 2, 1999, GlobeNet submitted a request to ANATEL seeking authority
to construct, land and operate the 360AMERICAS cable in Brazil. On October 13,
1999, in a response to this request, ANATEL indicated that the provision of
submarine cable infrastructure does not constitute a


                                       94
<PAGE>

telecommunications service and therefore no ANATEL license is necessary to
construct, own and operate the 360AMERICAS cable.



    Established regulations and procedures exist for obtaining
telecommunications services licenses in Brazil. Our operating subsidiary in
Brazil has received the necessary telecommunications services licenses from
ANATEL to provide backhaul services in Brazil. It is GlobeNet's expectation that
we will be able to sell or lease submarine cable fiber optic facilities to all
entities with authority to provide telecommunication services in Brazil. Under
the current regulatory regime in Brazil only Embratel and INTELIG have the
appropriate authority to offer long-distance and international switched voice
telephony services in Brazil. ANATEL is currently providing licenses on a
routine basis for companies seeking to offer international private network
services. It is not anticipated that regulatory authority will be required for
carrier-to-carrier contracts or the offering of value-added services. Thus,
today GlobeNet should be able to sell its facilities to the two public switched
telephony licensees, all private line licensees and value-added service
providers. The government of Brazil has announced that in January 2002, it will
lift current restrictions on the number of licensees in Brazil who may provide
switched voice telephony. At that time, GlobeNet should also be able to offer
our facilities to new competitive switched voice telephony providers.



VENEZUELA





    On March 16, 1999, GlobeNet submitted a letter to CONATEL seeking guidance
on what licenses or permits from CONATEL may be necessary to land the
360AMERICAS cable in Venezuela. In response to this letter, CONATEL informed
GlobeNet in writing that no authorization or permit from CONATEL is required to
construct and land the 360AMERICAS cable in Venezuela. Based on advice provided
by CONATEL, GlobeNet does not believe that any CONATEL permits or concessions
are necessary to operate the cable or sell capacity on the cable. In order to
provide backhaul services in Venezuela, GlobeNet must obtain a Private Network
Concession, which is required under Venezuelan law to install and operate a
telecommunications network for commercial purposes. GlobeNet shortly plans to
submit an application to CONATEL for this license. Although GlobeNet cannot
assure you that it will be granted this license, GlobeNet does not believe that
it will not be successful in obtaining it. It is GlobeNet's expectation that it
will be able to sell or lease submarine cable fiber optic facilities to all
entities with authority to provide telecommunications and value added network
services in Venezuela. Under the existing regulatory framework in Venezuela,
only CANTV can offer international public switched telephony services in
Venezuela. However, the Concession Agreement between the Republic of Venezuela
and CANTV provides that in November 2000 the telecommunications market will be
open for additional competition and the appropriate authority will be granted to
a number of companies seeking to offer switched voice telephony services.
Currently, CONATEL is issuing authority on a routine basis to companies seeking
to offer international or domestic private network services. Thus, today
GlobeNet can sell facilities to CANTV and private network and value added
service providers. Additionally, in November 2000 GlobeNet will be able to sell
facilities to newly licensed switched voice telephony providers.

Notes, which were issued pursuant to the 1998 Indenture, accrue interest at a
rate of 12 1/2% per annum. Interest is payable each June 15 and December 15,
commencing on June 15, 1999.



    RANKING.  The 1998 Notes rank senior in right of payment to any of our
future subordinated indebtedness and PARI PASSU in right of payment with all of
our senior indebtedness, including the 1999 Notes.


    OPTIONAL REDEMPTION.  The 1998 Notes are not redeemable prior to
December 31, 2003. Thereafter, the 1998 Notes will be redeemable, in whole or in
part, at our option, at the redemption prices set forth in the 1998 Indenture,
plus accrued and unpaid interest to the applicable redemption date.
Specifically, if redeemed during the 12-month period beginning on December 31 of
the years set forth below, the redemption price will be that amount, expressed
as a percentage of the principal amount of the 1998 Notes, listed below:

<TABLE>

    Despite the foregoing, however, we shall not be permitted to make an
optional redemption until we consummate an offer with respect to the amount of
cash generated by us which is not used for the provision of taxes, fixed
charges, extraordinary losses or to repay secured indebtedness (the "Accumulated
Excess Cash Flow Amount") existing at December 31, 2003 as described in "Excess
Cash Flow Offer" below.

    In addition, (1) prior to December 15, 2001, we may redeem up to 35% of the
originally issued principal amount of the 1998 Notes at 112.5% of their
principal amount, plus accrued and unpaid interest through the redemption date,
with the net cash proceeds of one or more public equity offerings; PROVIDED,
HOWEVER, that at least 65% of the originally issued principal amount of the 1998
Notes remains outstanding after the occurrence of the redemption and (2) we may
redeem the 1998 Notes at their face value if we become obligated to pay any
additional amounts as a result of change in the laws or regulations of Canada or
any Canadian taxing authority, or a change in any official position regarding
their application or interpretation.

    CHANGE OF CONTROL.  Upon the occurrence of a change of control, each holder
of 1998 Notes will have the right to require us to repurchase all or any part of
that holder's 1998 Notes at a purchase price in cash equal to 101% of their
principal amount, plus accrued and unpaid interest to the date of purchase.

    EXCESS CASH FLOW OFFER.  If at the end of our fiscal quarter ended
December 31, 2000 or any fiscal quarter ending on June 30 or December 31
thereafter, our Accumulated Excess Cash Flow Amount exceeds $10.0 million, we
will be required to make an offer to all holders of 1998 Notes to purchase the
maximum principal amount of 1998 Notes that may be purchased using that
Accumulated Excess Cash Flow Amount at an offer price equal to 110% of the
principal amount of the 1998 Notes, plus accrued and unpaid interest to the date
of purchase, subject to a limitation that we are not obliged to repurchase more
than 25% of the original principal amount of the 1998 Notes before December 31,
2003.


    COVENANTS.  The 1998 Indenture contains certain covenants that, among other
things, limit our ability and the ability of our restricted subsidiaries to:


    - borrow money;

    - pay dividends on stock or repurchase stock;

    - make investments;

    - use assets as security in other transactions; and

    - sell certain assets or merge with or into other companies.


    EVENTS OF DEFAULT.  The 1998 Indenture contains customary events of default,
including:


    - defaults in the payment of principal, premium or interest;


    - defaults in the compliance with covenants contained in the 1998 Indenture;


    - cross defaults on more than $10 million of other indebtedness;

    - failure to pay more than $10 million of judgments that have not been
      stayed by appeal or otherwise; and


    - the bankruptcy of 360NETWORKS INC. or certain of its subsidiaries.



360ATLANTIC CREDIT FACILITY



    In February 2000, a group of our subsidiaries entered into $565 million
senior secured credit facilities arranged by Goldman Sachs Credit Partners L.P.,
DLJ Capital Funding, Inc., Credit Suisse First Boston and Export Development
Corporation. This credit facility consists of a $365 million tranche A term loan
facility, a $175 million tranche B term loan facility and a $25 million working
capital revolving credit facility. Our subsidiaries have borrowed $100 million
under this credit facility and will use these proceeds, as well as future
proceeds, for the development, design, engineering, construction and
installation of 360ATLANTIC.



    The indebtedness outstanding under this credit facility is guaranteed by
four of our subsidiaries within the borrowing group and is secured by all of
their capital stock and substantially all of the assets and property owned by
our subsidiaries within the borrowing group. This credit facility is
non-recourse to 360NETWORKS INC.



    The credit facility contains customary covenants which restrict and limit
the ability of our subsidiaries within the borrowing group with respect to,
among other things, incurring indebtedness, entering into merger or
consolidation transactions, making certain restricted payments, creating liens
on assets, making investments and entering into sale and leaseback transactions
and transactions with affiliates. The credit facility also limits the ability of
our subsidiaries within the borrowing group to engage in activities unrelated to
360ATLANTIC. In addition, the credit facility also requires that our
subsidiaries within the borrowing group comply with various


                                       98
<PAGE>

financial covenants, including the receipt of a minimum amount of revenue
derived from sales of capacity on 360ATLANTIC, maximum leverage ratios and a
limit on capital expenditures.



    The credit facility also contains customary events of default, including the
nonpayment of principal, interest, fees or other amounts, a cross-default with
respect to other obligations of our subsidiaries within the borrowing group,
failure to materially comply with certain covenants, conditions or provisions
under the credit facility, the making of materially false or misleading
representations or warranties, the occurrence of any default under material
contracts related to 360ATLANTIC that could have a material adverse effect on
our subsidiaries within the borrowing group, the failure to achieve the
commercial operation date of 360ATLANTIC by a specified date, the occurrence of
reorganization, bankruptcy, insolvency or similar proceedings or the occurrence
of a change of control. Upon the occurrence and during the continuance of an
event of default under the credit facility, all obligations under the credit
facility could be deemed to be immediately due and payable.

         MATERIAL UNITED STATES AND CANADIAN INCOME TAX CONSIDERATIONS


    In this section we summarize the material U.S. federal and Canadian federal
income tax consequences of the ownership and disposition of Subordinate Voting
Shares beneficially owned by individuals, corporations, trusts and estates
which:



    - for purposes of the U.S. Internal Revenue Code of 1986, as amended through
      the date hereof (the "Code"), are U.S. persons and, for purposes of the
      Income Tax Act (Canada) (the "Income Tax Act") and the Canada-United
      States Income Tax Convention, are residents of the United States and not
      resident in Canada;



    - hold Subordinate Voting Shares as capital assets for purposes of the Code
      and capital property for purposes of the Income Tax Act;


    - deal at arm's length with us for purposes of the Income Tax Act; and


    - do not and will not use or hold the Subordinate Voting Shares in carrying
      on a business in Canada.


    We will refer to persons who satisfy the above conditions as "Unconnected
U.S. Shareholders."


    The tax consequences of an investment in Subordinate Voting Shares by
persons who are not Unconnected U.S. Shareholders may differ materially from the
tax consequences discussed in this section. The Income Tax Act contains rules
relating to securities held by some financial institutions. We do not discuss
these rules and holders that are financial institutions should consult their own
tax advisors.


    This discussion is based upon the following, all as currently in effect:

    - the Income Tax Act and regulations under the Income Tax Act;

    - the Code and Treasury regulations under the Code;

    - the Canada-United States Income Tax Convention (1980);

    - the administrative policies and practices published by the Canadian
      Customs and Revenue Agency, formerly Revenue Canada;

    - all specific proposals to amend the Income Tax Act and the regulations
      under the Income Tax Act that have been publicly announced by or on behalf
      of the Minister of Finance (Canada) prior to the date of this registration
      statement;

    - the administrative policies published by the U.S. Internal Revenue
      Service; and

    - judicial decisions.

    All of the foregoing are subject to change either prospectively or
retroactively. We do not take into account the tax laws of the various provinces
or territories of Canada or the tax laws of the various state and local
jurisdictions of the United States or foreign jurisdictions.


    THIS DISCUSSION SUMMARIZES THE MATERIAL U.S. FEDERAL AND CANADIAN FEDERAL
INCOME TAX CONSIDERATIONS OF THE OWNERSHIP AND DISPOSITION OF SUBORDINATE VOTING
SHARES. THIS DISCUSSION DOES NOT ADDRESS ALL POSSIBLE TAX CONSEQUENCES RELATING
TO AN INVESTMENT IN SUBORDINATE VOTING SHARES. WE HAVE NOT TAKEN INTO ACCOUNT
YOUR PARTICULAR CIRCUMSTANCES AND DO NOT ADDRESS CONSEQUENCES PECULIAR TO YOU IF
YOU ARE SUBJECT TO SPECIAL PROVISIONS OF U.S. OR CANADIAN INCOME TAX LAW
(INCLUDING, WITHOUT LIMITATION, DEALERS IN SECURITIES OR FOREIGN CURRENCY,
TAX-EXEMPT ENTITIES, BANKS, INSURANCE COMPANIES OR OTHER FINANCIAL INSTITUTIONS,
PERSONS THAT HOLD SUBORDINATE VOTING SHARES AS PART OF A "STRADDLE," "HEDGE" OR
"CONVERSION TRANSACTION," AND UNCONNECTED U.S. SHAREHOLDERS THAT HAVE A
"FUNCTIONAL CURRENCY" OTHER THAN


                                      100
<PAGE>

THE U.S. DOLLAR OR THAT OWN SUBORDINATE VOTING SHARES THROUGH A PARTNERSHIP OR
OTHER PASS-THROUGH ENTITY). THEREFORE, YOU SHOULD CONSULT YOUR OWN TAX ADVISOR
REGARDING THE TAX CONSEQUENCES OF PURCHASING SUBORDINATE VOTING SHARES IN THIS
OFFERING.


U.S. FEDERAL INCOME TAX CONSIDERATIONS


    Subject to the discussion below regarding Foreign Personal Holding Company
Rules, Passive Foreign Investment Company Rules and Controlled Foreign
Corporation Rules, this section summarizes U.S. federal income tax consequences
of the ownership and disposition of Subordinate Voting Shares.



    As an Unconnected U.S. Shareholder, you generally will be required to
include in income dividend distributions paid by us to the extent of our current
or accumulated earnings and profits attributable to the distribution as computed
based on U.S. income tax principles. The amount of any cash distribution paid in
Canadian dollars will be equal to the U.S. dollar value of the Canadian dollars
on the date of distribution based on the exchange rate on such date, regardless
of whether the payment is in fact converted to U.S. dollars and without
reduction for Canadian withholding tax. (For a discussion of Canadian
withholding taxes applicable to dividends paid by us, see "Certain Canadian
Federal Income Tax Considerations.") You will generally be entitled to a foreign
tax credit or deduction in an amount equal to the Canadian tax withheld. To the
extent distributions paid by us on the Subordinate Voting Shares exceed our
current or accumulated earnings and profits, they will be treated first as a
return of capital up to your adjusted tax basis in the shares and then as
capital gain from the sale or exchange of the shares.


    Dividends paid by us generally will constitute foreign source dividend
income and "passive income" for purposes of the foreign tax credit, which could
reduce the amount of foreign tax credits available to you. The Code applies
various limitations on the amount of foreign tax credits that may be available
to a U.S. taxpayer. Because of the complexity of those limitations, you should
consult your own tax advisor with respect to the availability of foreign tax
credits.


    Dividends paid by us on the Subordinate Voting Shares generally will not be
eligible for the "dividends received" deduction.



    If you sell the Subordinate Voting Shares, you generally will recognize gain
or loss in an amount equal to the difference between the amount realized on the
sale and your adjusted tax basis in the shares. Any such gain or loss will be
long-term or short-term capital gain or loss, depending on whether the shares
have been held by you for more than one year, and will generally be U.S. source
gain or loss.



    Dividends paid by us on the Subordinate Voting Shares generally will not be
subject to U.S. information reporting or the 31% backup withholding tax unless
they are paid in the United States through a U.S. or U.S.-related paying agent,
including a broker. If you furnish the paying agent with a duly completed and
signed Form W-9, such dividends will not be subject to the backup withholding
tax. You will be allowed a refund or a credit equal to any amount withheld under
the U.S. backup withholding tax rules against your U.S. federal income tax
liability, provided you furnish the required information to the Internal Revenue
Service.


FOREIGN PERSONAL HOLDING COMPANY RULES

    Special U.S. tax rules apply to a shareholder of a foreign personal holding
company ("FPHC"). We would be classified as a FPHC in any taxable year if both
of the following tests are satisfied:

    - five or fewer individuals who are U.S. citizens or residents own or are
      deemed to own more than 50% of the total voting power of all classes of
      our stock entitled to vote or the total value of our stock; and

                                      101
<PAGE>
    - at least 60% of our gross income consists of "foreign personal holding
      company income," which generally includes passive income such as
      dividends, interest, gains from the sale or exchange of stock or
      securities, rents and royalties.

    We believe that we are not a FPHC, and we do not expect to become a FPHC as
a result of the offering. However, we can not assure you that we will not
qualify as a FPHC in the future.

PASSIVE FOREIGN INVESTMENT COMPANY RULES

    The passive foreign investment company ("PFIC") provisions of the Code can
have significant tax effects on Unconnected U.S. Shareholders. We could be
classified as a PFIC if, after the application of certain "look through" rules,
for any taxable year, either:

    - 75% or more of our gross income is "passive income," which includes
      interest, dividends and certain rents and royalties; or

    - the average quarterly percentage, by fair market value of our assets that
      produce or are held for the production of "passive income" is 50% or more
      of the fair market value of all our assets.

    To the extent we own at least 25% by value of the stock of another
corporation, we are treated for purposes of the PFIC tests as owning our
proportionate share of the assets of such corporation, and as receiving directly
our proportionate share of the income of such corporation.


    Distributions which constitute "excess distributions" from a PFIC and
dispositions of Subordinate Voting Shares of a PFIC are subject to the following
special rules: (1) the excess distributions (generally any distributions
received by an Unconnected U.S. Shareholder on the shares in any taxable year
that are greater than 125% of the average annual distributions received by such
Unconnected U.S. Shareholder in the three preceding taxable years, or the
Unconnected U.S. Shareholder's holding period for the shares, if shorter) or
gain would be allocated ratably over an Unconnected U.S. Shareholder's holding
period for the shares, (2) the amount allocated to the current taxable year and
any taxable year prior to the first taxable year in which we are a PFIC would be
treated as ordinary income in the current taxable year, and (3) the amount
allocated to each of the other taxable years would be subject to the highest
rate of tax on ordinary income in effect for that year and to an interest charge
based on the value of the tax deferred during the period during which the shares
are owned.


    Subject to specific limitations, Unconnected U.S. Shareholders who actually
or constructively own marketable shares in a PFIC may make an election under
section 1296 of the Code to mark those shares to market annually, rather than
being subject to the above-described rules. Amounts included in or deducted from
income under this mark-to-market election and actual gains and losses realized
upon disposition, subject to specific limitations, will be treated as ordinary
gains or losses. For this purpose, we believe that our shares will be treated as
"marketable securities" within the meaning of Section 1296(e)(1) of the Code.

    We believe that we will not be a PFIC for the current fiscal year and we do
not expect to become a PFIC in future years. Whether we are a PFIC in any year
and the tax consequences relating to PFIC status will depend on the composition
of our income and assets, including cash. You should be aware, however, that if
we are or become a PFIC we may not be able or willing to satisfy record-keeping
requirements that would enable you to make a "qualified electing fund" election.
You should consult your tax advisor with respect to how the PFIC rules affect
your tax situation.

                                      102
<PAGE>
CONTROLLED FOREIGN CORPORATION RULES

    If more than 50% of the voting power or total value of all classes of our
shares is owned, directly or indirectly, by U.S. shareholders, each of which
owns 10% or more of the total combined voting power of all classes of our
shares, we could be treated as a controlled foreign corporation ("CFC") under
Subpart F of the Code. This classification would require such 10% or greater
shareholders to include in income their pro rata shares of our "Subpart F
Income," as defined in the Code. In addition, under Section 1248 of the Code,
gain from the sale or exchange of shares by an Unconnected U.S. Shareholder who
is or was a 10% or greater shareholder at any time during the five year period
ending with the sale or exchange will be ordinary dividend income to the extent
of our earnings and profits attributable to the shares sold or exchanged.

    We believe that we are not a CFC and we will not become a CFC as a result of
the offering. However, we can not assure you that we will not become a CFC in
the future.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS


    In this section, we summarize the material anticipated Canadian federal
income tax considerations relevant to your purchase of Subordinate Voting
Shares.



    Under the Income Tax Act, assuming you are an Unconnected U.S. Shareholder,
and provided the Subordinate Voting Shares are listed on a prescribed stock
exchange, which includes The Toronto Stock Exchange and Nasdaq, you will
generally be exempt from Canadian tax on a capital gain realized on an actual or
deemed disposition of the Subordinate Voting Shares unless you alone or together
with persons with whom you did not deal at arm's length owned or had rights to
acquire 25% or more of our issued shares of any class at any time during the
five year period before the actual or deemed disposition.



    Dividends paid, credited or deemed to have been paid or credited on the
Subordinate Voting Shares to Unconnected U.S. Shareholders will be subject to a
Canadian withholding tax at a rate of 25% under the Income Tax Act. Under the
Canada-United States Income Tax Convention, the rate of withholding tax on
dividends generally applicable to Unconnected U.S. Shareholders who beneficially
own the dividends is reduced to 15%. In the case of Unconnected U.S.
Shareholders that are corporations that beneficially own at least 10% of our
voting shares, the rate of withholding tax on dividends is reduced to 5%.



    Canada does not currently impose any estate taxes or succession duties.
However, if you die, there is generally a deemed disposition of the Subordinate
Voting Shares held at that time for proceeds of disposition equal to the fair
market value of the Subordinate Voting Shares immediately before the death.
Capital gains realized on the deemed disposition, if any, will have the income
tax consequences described above.

Credit Suisse First Boston Corporation, TD Securities Inc., Bear, Stearns &
Co. Inc., BMO Nesbitt Burns Inc., Morgan Stanley & Co. Incorporated, Chase
Securities Inc., RBC Dominion Securities Inc. and Warburg Dillon Read LLC will,

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


    The underwriting agreement provides that the obligations of the Underwriters
to purchase the Subordinate Voting Shares listed above are subject to certain
conditions set forth therein. The Underwriters are committed to purchase all of
the Subordinate Voting Shares offered by this prospectus (other than those
covered by the Underwriters' over-allotment option described below), if any are
purchased. In the event of default by any Underwriter, the underwriting
agreement provides that, in certain circumstances, the purchase commitments of
the non-defaulting Underwriters may be increased or the underwriting agreement
may be terminated. The obligations of the Underwriters under the underwriting
agreement are several and may be terminated in their discretion on the basis of
their assessment of the state of the financial markets and upon the occurrence
of certain stated events.



    We, our officers, directors and substantially all of our shareholders have
agreed with the Underwriters not to dispose of or hedge any of their Subordinate
Voting Shares or securities convertible into or exchangeable for shares of
Subordinate Voting Shares during the period from the date of this prospectus
continuing through the periods set forth herein after the date of this
prospectus, except with the prior written consent of Goldman, Sachs & Co.,
Donaldson, Lufkin & Jenrette Securities Corporation and 360NETWORKS. See "Shares
Eligible for Future Sale".



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



    In addition, in the U.S. the Underwriters also may impose a penalty bid.
This occurs when a particular Underwriter repays to the Underwriters a portion
of the underwriting discount received by it because the representatives have
repurchased shares sold by or for the account of such Underwriter in stabilizing
or short covering transactions. These activities by the Underwriters may
stabilize, maintain or otherwise affect the market price of the Subordinate
Voting Shares. As a result, the price of the Subordinate Voting Shares may be
higher than the price that otherwise might exist in the open market. If these
activities are commenced, they may be discontinued by the


                                      105
<PAGE>

Underwriters at any time. These transactions may be effected on the Nasdaq
National Market ("Nasdaq"), in the over-the-counter market or otherwise.



    Pursuant to policy statements issued by the Ontario Securities Commission
and the Commission des valeurs mobilieres du Quebec, the Underwriters may not,
throughout the period of distribution, bid for or purchase Subordinate Voting
Shares. The foregoing restriction is subject to certain exceptions, on the
condition that the bid or purchase not be engaged in for the purpose of creating
actual or apparent active trading in or raising the price of the Subordinate
Voting Shares. Those exceptions include a bid or purchase permitted under the
by-laws and rules of The Toronto Stock Exchange relating to market stabilization
and passive market making activities and a bid or purchase made for or on behalf
of a customer where the order was not solicited during the period of
distribution. Subject to the foregoing, in connection with this offering and
pursuant to the first-mentioned exception, the Underwriters may over-allot or
effect transactions which stabilize or maintain the market price of the
Subordinate Voting Shares at levels other than those which might otherwise
prevail on the open market. Such transactions, if commenced, may be discontinued
at any time.



    Application will be made to approve the Subordinate Voting Shares for
quotation on Nasdaq under the symbol "TSIX " and for listing on The Toronto
Stock Exchange under the symbol "TSX".



    Prior to the offering, there has been no public market for the Subordinate
Voting Shares. Consequently, the initial public offering price has been
determined through negotiations among us and Goldman, Sachs & Co. and Donaldson,
Lufkin & Jenrette Securities Corporation on behalf of the Underwriters. Among
the factors considered in making such determination were the prevailing market
conditions, our financial condition, our prospects and the prospects for our
industry in general, our management and the market prices of securities for
companies in businesses similar to ours.



    The Underwriters do not expect sales to discretionary accounts to exceed
five percent of the total number of shares offered.



    We estimate that our share of the total expenses of the offering, excluding
underwriting discounts and commissions, will be approximately $               .



    We and the selling shareholder have agreed to indemnify the several
Underwriters against certain liabilities, including liabilities under the
Securities Act of 1933.



    At our request, the Underwriters have reserved, at the initial public
offering price, approximately 5% of the Subordinate Voting Shares to be sold in
this offering for sale to our directors and employees and directors and
employees of our affiliates and certain other persons.


    The number of shares available for sale to the general public will be
reduced by the number of reserved shares sold. Any reserved shares not so
purchased will be offered by the Underwriters to the general public on the same
basis as other shares offered hereby.


    On September 9, 1999, affiliates of each of Goldman, Sachs & Co. and
Donaldson, Lufkin & Jenrette Securities Corporation invested in a private
placement of our redeemable convertible preferred shares. These shares will be
converted or exchanged into Subordinate Voting Shares concurrently with the
closing of this offering. Pursuant to a purchase price adjustment provision in
the purchase agreement governing the private placement, additional preferred
shares were issued to such affiliates in February 2000 and March 2000, upon the
issuance of Subordinate Voting Shares to CN and Michels, respectively, in
exchange for its interests in certain of our subsidiaries. In December 1999,
pursuant to that same purchase price adjustment provision, additional preferred
shares were again issued to such affiliates concurrently with the purchase by
Mr. Gregory Maffei, our Chief Executive Officer, of our capital stock. In
addition, under a shareholders agreement entered into in connection with the
preferred share purchase, each such affiliate received the right to designate a
member to our board of directors. For more information, please refer to the
section entitled "Management."

          ENFORCEABILITY OF CIVIL LIABILITIES AGAINST FOREIGN PERSONS


    We are a corporation organized under the laws of Canada. We intend to
continue under the laws of Nova Scotia, Canada prior to the closing of this
offering. A majority of our directors and officers, as well as certain experts
named in this prospectus, reside principally in Canada. Because all or a
substantial portion of our assets and the assets of these persons are located
outside the United States, it may not be possible for you to effect service of
process within the United States upon us or those persons. Furthermore it may
not be possible for you to enforce against us or them in the United States,
judgments obtained in U.S. courts based upon the civil liability provisions of
the U.S. Federal securities laws or other laws of the United States. We have
been advised by Farris, Vaughan, Wills & Murphy, our Canadian counsel, that
there is doubt as to the enforceability, in original actions in Canadian courts,
of liabilities based upon the U.S. Federal securities laws and as to the
enforceability in Canadian courts of judgments of U.S. courts obtained in
actions based upon the civil liability provisions of the U.S. Federal securities
laws. Therefore, it may not be possible to enforce those actions against us, our
directors and officers or the experts named in this prospectus.

2.  BASIS OF PRESENTATION


    The unaudited pro forma consolidated balance sheet and consolidated income
statement have been prepared by management in accordance with generally accepted
accounting principles in the United States and the pro forma assumptions and
adjustments described in notes 1, 4 and 5.



    The unaudited pro forma consolidated balance sheet and income statement as
at and for the year ended December 31, 1999 are based on the audited historical
consolidated financial statements of the Company for the year ended
December 31, 1999 and audited historical consolidated financial statements of
GlobeNet for the year ended December 31, 1999.



    The unaudited pro forma financial statements give effect to the acquisition
by the Company of GlobeNet in a transaction to be accounted for as a purchase.
The unaudited pro forma consolidated balance sheet is based on the individual
balance sheets of the Company and GlobeNet, and has been prepared to reflect the
acquisition by the Company of GlobeNet as of December 31, 1999. The unaudited
proforma income statement is based on the individual statements of income of the
Company and GlobeNet and combines the results of the operations for the year
ended December 31, 1999 as if the acquisition occurred on January 1, 1999.

</TABLE>



    Goodwill will be amortized over 25 years. The purchase price allocation is
preliminary subject to management's due diligence and the execution of
definitive agreements, which may result in a different allocation than presented
in these pro forma financial statements. This may result in a re-allocation of
the excess of cost over the book value of net assets to pro forma inventory,
property and equipment, assets under construction or long-term debt.



    (III) ISSUANCE OF $1,000,000,000 12% NOTES



    This adjustment records the issuance of $1,000,000,000 12% notes due 2010
(the "Notes") assuming the Notes were issued on December 31, 1999. Commissions
of $25,000,000 and issuance expenses of $1,000,000 have been recorded as
deferred financing costs which will be amortized over 10 years using the
effective interest rate method.



    (IV) CANADIAN TELECOMMUNICATIONS ARRANGEMENT OF CERTAIN ASSETS



    This adjustment records the transfer of certain telecommunications
facilities included in property & equipment to a company (the "transferee")
owned 66 2/3% by a subsidiary of Ledcor and 33 1/3% by the Company. This
transaction is recorded at the carrying value of the assets transferred of
$6,444,000 as the transaction is between parties under common control. The
Company's investment in the transferee is recorded using the equity basis of
accounting.

    This adjustment records the Company's acquisition of the shares in WFI USA
in exchange for 18,352,941 Subordinate Voting Shares of the Company. This

    Goodwill will be amortized over 25 years. The purchase price allocation is
preliminary subject to a detailed assessment of the fair values of the
underlying assets. This assessment may result in a re-allocation of the excess

equipment and assets under construction.

    This adjustment records the Company's acquisition of the shares in WFI-CN

connection with the issuance of Subordinate Voting Shares to CN, IC and Michels.



    (VIII) CONVERSION OR EXCHANGE OF SERIES A NON-VOTING PREFERRED SHARES INTO
     SUBORDINATE VOTING SHARES



    This adjustment records the conversion or exchange of all issued and
outstanding Series A Non-Voting Preferred Shares into Subordinate Voting Shares.



    (IX) SHARE CAPITAL REORGANIZATION



    This adjustment records the reorganization of share capital as follows:



    - The conversion of all outstanding Class B Subordinate Voting Shares into
      Class A Non-Voting Shares



    - The redesignation of all outstanding Class A Non-Voting Shares to
      Subordinate Voting Shares

      Multiple Voting Shares.



5.  PRO FORMA CONSOLIDATED INCOME STATEMENT ASSUMPTIONS AND ADJUSTMENTS FOR THE
    YEAR ENDED DECEMBER 31, 1999



    (I) ACQUISITION OF GLOBENET



    The pro forma income statement has been prepared to reflect the following
adjustments and assumptions resulting from the acquisition of GlobeNet:



    - This elimination of the amortization of deferred financing costs of
      $1,310,000 related to GlobeNet's debt.



    - The amortization of goodwill of $20,710,000.



    - The assumption that GlobeNet's long term debt will not be repaid as a
      result of a change in control of GlobeNet. If the Company had repurchased
      GlobeNet's $300,000,000 13% notes using proceeds from the Notes assumed to
      have an interest rate of 12%, pro forma interest expense net of taxes
      would be lower by $768,000 and an extraordinary loss net of taxes of
      $1,632,000 would have been recorded as a result of the premium paid on
      redemption of GlobeNet's notes.

    YEAR ENDED DECEMBER 31, 1999 (CONTINUED)


    (II) MICHELS AND CN/IC MINORITY INTEREST ACQUISITIONS



    This adjustment records the amortization of goodwill from the acquisition of
the minority equity interests of Michels and CN/IC and elimination of minority
interest earnings assuming the acquisitions occurred on January 1, 1999.



    (III) INTEREST EXPENSE ON THE NOTES AND 1999 NOTES



    This adjustment records the interest expense, including amortization of
deferred financing costs of $158,971,000 for the year ended December 31, 1999
assuming the Notes and the 1999 Notes were issued on January 1, 1999.
Amortization of the deferred financing costs was computed based on the effective
interest rate method. The Company would have capitalized a portion of interest
expense related to the Notes and the 1999 Notes to the cost of the fiber optic
network assets constructed in 1999, which is not reflected in these pro forma
statements.



    (IV) INCOME TAXES



    This adjustment records an income tax recovery of $40,615,000 for 1999 using
an effective tax rate of 45.6%. Management believes that, based on a number of
factors, it is more likely than not that the deferred tax asset will be fully
realized, such that no valuation allowance would be recorded.



    (V) CAPITAL TAXES



    This adjustment records estimated additional BC Corporation Capital taxes of
$4,970,000 for 1999 and Federal Large Corporation taxes of $3,730,000 for 1999
resulting from the proforma adjustments in notes 4 and 5.

                                AUDITORS' REPORT


TO THE DIRECTORS AND SHAREHOLDERS OF
360NETWORKS INC. (FORMERLY WORLDWIDE FIBER INC.)



    We have audited the consolidated balance sheets of 360NETWORKS INC.
(formerly Worldwide Fiber Inc.) as at December 31, 1999 and 1998 and the
consolidated income statements and statements of changes in shareholders' equity
and cash flows for the year ended December 31, 1999 and for the period from
February 5, 1998 (date of incorporation) to December 31, 1998. 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 in the United States. Those standards require that we plan and perform
an audit to obtain reasonable assurance 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.



    In our opinion, these consolidated financial statements present fairly, in
all material respects, the financial position of the Company as at December 31,
1999 and 1998 and the results of its operations and its cash flows for the year
ended December 31, 1999 and for the period from February 5, 1998 (date of
incorporation) to December 31, 1998 in accordance with generally accepted
accounting principles in the United States.



    On February 25, 2000 except for Note 16 which is as of March 20, 2000, we
reported separately to the Directors of 360NETWORKS INC. on consolidated
financial statements for the year ended December 31, 1999 and period from
February 5, 1998 (date of incorporation) to December 31, 1998 prepared in
accordance with generally accepted accounting principles in Canada.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


                           DECEMBER 31, 1999 AND 1998



            (TABULAR AMOUNTS EXPRESSED IN THOUSANDS OF U.S. DOLLARS)


    1.  THE COMPANY


    360NETWORKS INC. (formerly Worldwide Fiber Inc.) (the "Company") was
incorporated on February 5, 1998 and is indirectly a subsidiary of Ledcor Inc.
On May 31, 1998 the Company began its operations after certain assets of the
Telecommunications Division ("Division") of Ledcor Industries Limited
("Ledcor"), a Ledcor Inc. subsidiary were transferred to the Company. Prior to
May 31, 1998, the operations were carried out by the Division.



    The Company's operations consist of designing, engineering, constructing and
installing terrestrial and marine fiber optic systems for sale or lease to third
parties or for its own use. For the period ended December 31, 1998, the
Company's revenues related primarily to the Construction Services Agreements
with Ledcor (see note 1(b)). For the year ended December 31, 1999, the Company's
revenue is derived primarily from the construction of fibre optic network assets
for telecommunications companies in North America.



    TRANSACTIONS WITH LEDCOR AND ITS AFFILIATES



        a) On May 31, 1998, the Company entered into undertaking agreements
    whereby certain fiber optic network assets, located in Canada and the U.S.
    would be transferred to the Company by Ledcor in exchange for 319,995,200
    Class A Non-Voting Shares. The Company constructed these assets for Ledcor
    under the Construction Services Agreements noted below. Construction of the
    assets was substantially complete at December 31, 1998 and the Company
    completed the exchange on March 31, 1999. This transaction was accounted for
    using the carrying values reported in the accounts of Ledcor as a
    transaction between a parent and a wholly owned subsidiary and accordingly,
    the fixed assets acquired by the Company are recorded at the carrying amount
    of the assets in the accounts of Ledcor. The cost of property and equipment
    acquired at March 31, 1999 amounted to $21,883,000. As a result of the
    transaction, the Company also received a deferred tax benefit of $3,136,000
    which is reflected as a deferred tax asset.



        On May 28, 1999, the Company entered into an agreement with affiliates
    of Ledcor, whereby the Company would acquire certain fiber optic network
    assets. Closing occurred on September 27, 1999. As consideration, the
    Company issued 72,000,000 Class C Multiple Voting Shares to affiliates of
    Ledcor. In addition, the Company assumed certain rights and obligations
    under build agreements with a third party including obligations relating to
    the completion of those builds and certain support structure, maintenance,
    license and access, and underlying rights obligations. The cost of the
    property and equipment acquired amounted to $25,289,000, the cost of the
    assets in the accounts of Ledcor. The Company also received a deferred tax
    benefit of $3,341,000, as a result of a higher tax cost versus accounting
    cost of fixed assets. The Company also recorded deferred revenue of
    $25,000,000 relating to a build commitment assumed from Ledcor.



        b) Construction Services Agreements entered into May 31, 1998, to
    provide construction services to Ledcor to complete various projects
    including completion of the fiber optic network assets to be transferred to
    the Company. As the Company is required to obtain the fiber optic

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                           DECEMBER 31, 1999 AND 1998



            (TABULAR AMOUNTS EXPRESSED IN THOUSANDS OF U.S. DOLLARS)



    network assets from Ledcor, the revenues and costs associated with this
    portion of the agreement have not been reflected in the income statement for
    the period ended December 31, 1998. The costs to construct the network were
    reflected on completion of construction and the issuance of the shares. As
    at December 31, 1998, the Company had billed Ledcor $18,138,000 for the
    services related to construction of the fiber optic network assets which
    exceeds their costs by $2,099,000. This excess, net of income taxes of
    $945,000, had been excluded from the consolidated income statement and had
    been reported as additional paid in capital.



        c) A Management Services Agreement was entered into May 31, 1998 whereby
    Ledcor provides the Company with management staff, administrative and other
    support services. The Company reimburses Ledcor for direct costs and pays
    Cdn. $200,000 per month for the Company's share of corporate overheads.



        d) Employee Services Agreements were entered into May 31, 1998 whereby
    the Company obtains the services of certain employees from Ledcor on a cost
    reimbursement basis.



        e) The Company has entered into an agreement with Ledcor, whereby
    personnel of Ledcor who were involved in the designing and planning of the
    transatlantic 360ATLANTIC cable stations will oversee management and
    supervision of construction of these facilities for a fee to Ledcor of
    approximately $1,700,000.



    2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


    BASIS OF PRESENTATION


    These consolidated financial statements have been prepared in accordance
with generally accepted accounting principles in the United States and include
the accounts of the Company, its wholly owned subsidiaries and its 75% interests
in Worldwide Fiber (USA), Inc. ("WFI USA"), WFI-CN Fiber Inc. and Worldwide
Fiber IC LLC. All significant intercompany transactions and balances have been
eliminated on consolidation. For investments where the Company exercises
significant influence, the investment is accounted for using the equity method.



    On December 31, 1998, the Company increased its interest in WFI USA from 50%
to 75% (note 5). The 1998 consolidated income statement and statement of cash
flows accounted for the Company's initial 50% interest in WFI USA using the
equity method for the period May 31, 1998 to December 31, 1998. The Company's
consolidated balance sheets include WFI USA's assets and liabilities, and
minority interest therein.


    USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions which affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and revenues and expenses for the period reported. Actual results
could differ from those estimates.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                           DECEMBER 31, 1999 AND 1998



            (TABULAR AMOUNTS EXPRESSED IN THOUSANDS OF U.S. DOLLARS)


    CASH AND CASH EQUIVALENTS

    Cash and cash equivalents consists of cash on deposit and highly liquid
short-term interest bearing securities with maturity at the date of purchase of
three months or less.

    SHORT TERM INVESTMENTS

    Short term investments consist of highly liquid short term interest bearing
securities with maturities at the date of purchase greater than three months.
Interest earned is recognized immediately in the income statement.


    PROPERTY AND EQUIPMENT



    Fiber optic network assets constructed for the Company's own use are
recorded as property and equipment when the asset is fully constructed. Fiber
optic network assets, construction equipment and other property and equipment
are recorded at cost. Property and equipment are depreciated using the following
rates and methods:



    (a) Fiber optic network assets--straight-line method over 25 years.



    (b) Equipment--hourly usage rates, estimated to depreciate the equipment
       over the estimated useful lives of the equipment.



    ASSETS UNDER CONSTRUCTION



    Assets under construction include fiber optic network assets constructed for
the Company's own use and include direct expenditures of materials and labour,
indirect costs attributable to the projects and interest.



    LONG-LIVED ASSETS



    The company reviews the carrying amount of long-lived assets for impairment
whenever events or changes in circumstances indicate that the carrying amount
may not be recoverable. The determination of any impairment would include a
comparison of estimated future operating cash flows anticipated to be generated
during the remaining life of the asset to the net carrying value of the asset.


    INVENTORY

    Inventory consists of fiber optic network assets to be sold or leased under
sales-type leases, construction supplies and small tools.


    Fiber optic network assets are recorded at the lower of cost and market.
Cost includes direct materials and subcontractor charges, labour, and interest
(see "capitalization of interest") determined on an average cost basis.


    Construction supplies and small tools inventory are recorded at the lower of
cost and replacement value.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                           DECEMBER 31, 1999 AND 1998



            (TABULAR AMOUNTS EXPRESSED IN THOUSANDS OF U.S. DOLLARS)


    REVENUE RECOGNITION

    Revenue for services provided to Ledcor for construction projects is
recognized in the period the construction services are performed based on the
costs incurred.

    Revenue and income from construction contracts to develop fiber optic
network assets are determined on the percentage-of-completion basis using the
cost-to-cost method. Provision is made for all anticipated losses as soon as
they become evident. Claims for additional contract compensation are not
recognized until resolved.


    UNBILLED REVENUE



    Revenue recognized using the percentage-of-completion basis (see "Revenue
recognition") less billings to date is recorded as unbilled revenue. Unbilled
revenue classified as current represent billings expected to be collected within
the following fiscal year. Billings are rendered on the achievement of certain
construction milestones.


    CAPITALIZATION OF INTEREST


    Interest is capitalized as part of the cost of constructing fiber optic
network assets. Interest capitalized during the construction period is computed
by determining the average accumulated expenditures for each interim
capitalization period and applying the interest rate related to the specific
borrowings associated with each construction project. The total interest
capitalized in the year ended December 31, 1999 was $17,467,000 (December 31,
1998--$Nil).


    DEFERRED FINANCING COSTS

    Costs incurred in connection with obtaining the senior notes financing are
deferred and amortized, using the effective interest method, to interest expense
over the term of the senior notes.


    DEFERRED REVENUE



    Cash received from customers pursuant to contracts where construction has
not commenced is recorded as deferred revenue.


    FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS


    The functional currency of the Company's operations located in countries
other than the U.S. is generally the domestic currency. The consolidated
financial statements are translated to U.S. dollars using the period-end
exchange rate for assets and liabilities and weighted-average exchange rates for
the period for revenues and expenses. Translation gains and losses are deferred
and accumulated as a component of other comprehensive income in shareholders'
equity. Net gains and losses resulting from foreign exchange transactions are
included in the consolidated income statement.

            (TABULAR AMOUNTS EXPRESSED IN THOUSANDS OF U.S. DOLLARS)



    COMPREHENSIVE INCOME



    Comprehensive income consists of currency translation adjustments and net
income.


    INCOME TAXES


    Income taxes are accounted for using an asset and liability approach, which
requires the recognition of taxes payable or refundable for the current period
and deferred tax liabilities and assets for future tax consequences of events
that have been recognized in the Company's financial statements or tax returns.
The measurement of current and deferred tax liabilities and assets is based on
provisions of enacted tax laws; the effects of future changes in tax laws or
rates are not anticipated. The measurement of deferred tax assets is reduced, if
necessary, by a valuation allowance, where, based on available evidence, the
probability of realization of the deferred tax asset does not meet a more likely
than not criteria.


    FAIR VALUE OF FINANCIAL INSTRUMENTS


    The fair value of the Company's financial instruments, consisting of cash
and cash equivalents, short-term investments, accounts receivable, unbilled
revenue, due from parent, accounts payable and accrued liabilities, and income
taxes payable approximate their carrying values due to their short-term nature.
As at December 31, 1999, the fair value of the $500,000,000 12% Senior Notes was
$515,000,000 and the fair value of the $175,000,000 12.5% Senior Notes ("1998
Notes") was $182,000,000. The fair value of the 1998 Notes at December 31, 1998
approximated its carrying value. Fair value is based on a quoted market price.


    EARNINGS PER SHARE


    Basic earnings per share is computed by dividing net income available to
common stockholders by the weighted average number of common shares (including
Class A Non-Voting Shares, Class B Subordinate Voting Shares and Class C
Multiple Voting Shares) outstanding for the period. Diluted earnings per share
reflects the potential dilution of securities by including other potential
common stock, including stock options and redeemable convertible preferred
shares, in the weighted average number of common shares outstanding for a
period, if dilutive.



    The following table sets forth the computation of (loss) earnings per share:

    The Redeemable Convertible Preferred Shares and stock options are not
included in the computation of fully diluted earnings per share as their effect
is anti-dilutive.


    RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." This statement
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts and for
hedging activities. The Company does not expect the adoption of SFAS No. 133 to
have a material impact on its consolidated financial statements.


    In June 1999, the Financial Accounting Standards Boards (FASB) issued
Interpretation No. 43, "Real Estate Sales, an interpretation of FASB Statement
No. 66." The interpretation is effective for sales of real estate with property
improvements or integral equipment entered into after June 30, 1999. Under this
interpretation, title must transfer to a lessee in order for a lease transaction
to be accounted for as a sales-type lease. The accounting for indefeasible
rights of use of fiber optic network assets is evolving and currently being
considered by accounting standard setters in the U.S. These changes may have a
significant effect on the Company, however it is not possible to determine the
consequences of such changes until further accounting guidance has been
developed.

    5.  ACQUISITIONS

    TELECOMMUNICATIONS DIVISION ASSETS


    Effective May 31, 1998, the Company entered into a series of agreements
whereby equipment, fiber optic network assets and other assets related to the
business of the Telecommunications Division of Ledcor were transferred to the
Company. In addition, the Company was granted a license to use Ledcor's patented
rail plow technology. This license agreement was for an initial term

of ten years, renewable annually upon completion of the initial term. As part of
this transaction, Ledcor retained all existing construction contracts related to
the business. This transaction was between entities under common control and has
been accounted for using the carrying amounts recorded in Ledcor's accounts. The
tax basis of substantially all the Canadian assets transferred to the Company
was Ledcor's carrying values whereas the tax basis of the U.S. assets
transferred was their fair value. The deferred tax balances were adjusted for
the change in the tax basis of the U.S. assets with the adjustment being
reflected as additional paid in capital. As consideration for the transaction,
the Company issued 3,200 Class A Common Shares to Ledcor.


    The assets transferred and consideration given, in connection with this
transaction, were as follows:

    LEDCOM HOLDINGS LTD.


    On December 1, 1998 the Company acquired 50 Class A common Shares
representing a 50% interest of Ledcom Holdings Ltd. ("Ledcom") from Worldwide
Fiber Holdings Ltd. ("WFHL"), the Company's parent. As consideration, the
Company issued 32,000,000 Class A Non-Voting Shares. Ledcom holds the patent to
Ledcor's rail plow technology, and in conjunction with this acquisition Ledcor
has committed to grant to the Company a worldwide exclusive license for the use
of the rail plow technology. The license will become non-exclusive six months
after a change of control of the Company. This transaction was between entities
under common control and has been accounted for using the carrying value of the
investment recorded in WFHL's accounts which was $nil.


    INVESTMENT IN WFI USA


    On August 31, 1998, the Company purchased Ledcor's 50% interest in, and a
promissory note of $3,915,000 from WFI USA, in exchange for 48,000,000 Class A
Non-Voting Shares of the Company and the issuance of a promissory note by the
Company. WFI USA was a joint venture with Mi-Tech Communications LLC ("Mi-Tech")
which held the remaining 50% interest in WFI USA. WFI USA's operations consist
primarily of developing fiber optic network assets in the United States.



    As this transaction was between entities under common control, it was
accounted for in a manner similar to a pooling of interests. These financial
statements reflect the equity interest in the

income of WFI USA from May 31, 1998 to December 31, 1998 in the amount of
$928,000. Prior to May 31, 1998, the equity interest was reported as part of the
Telecommunications Division of Ledcor.



    On December 31, 1998 the Company increased its interest in WFI USA to 75% by
surrendering its note receivable from WFI USA of $3,915,000 for 100 non-voting
common shares and 100 Class A Voting Preferred Shares of WFI USA. The
acquisition has been accounted for using the purchase method effective
December 31, 1998. The purchase price of the additional 25% has been allocated
to assets and liabilities based on their fair values. As a result, the net
assets acquired were as follows:

    On December 31, 1998, the Company entered into a Shareholders' Agreement
("Agreement") with Ledcor, Mi-Tech and Michels Pipeline Construction, Inc.
("Michels") (an affiliate of Mi-Tech). Pursuant to this agreement, Mi-Tech will
have the option to convert all of its 25% interest in WFI USA into Shares of the
Company should the Company complete a public offering of Shares with an
aggregate value of at least $20,000,000 or there is a change of control of WFI
USA. In connection with the conversion, Mi-Tech will be granted certain
registration rights in accordance with the Agreement. In addition, after the
tenth anniversary of this agreement, Mi-Tech has the option to require WFI USA
to purchase all of the Shares owned by Mi-Tech and its affiliates at fair market
value. If Mi-Tech exercises this option, the Company can elect to sell all the
Shares or assets of WFI USA in which case it will not be required to purchase
Mi-Tech's Shares in WFI USA. In the event of a proposed sale of the Shares of
WFI USA held by the Company, Mi-Tech will have certain tag-along rights.


    Also as part of the Agreement the Company:



    a)  Agreed not to participate in any projects or business nor provide advice
       or assistance to any business which undertakes projects within WFI USA's
       scope of business, as defined in the Agreement, for a period of four
       years from the date of the Agreement.



    b)  Is restricted from selling, transferring, encumbering or divesting its
       ownership or control of WFI USA.



    c)  WFI USA has an option to purchase from Mi-Tech 24 fiber optic strands
       along certain existing routes owned by Mi-Tech and its affiliates at fair
       market value.

    6.  DUE FROM PARENT


    The amounts due to and from parent are non-interest bearing, have no stated
terms of repayment and are due on demand. Contract amounts billed to parent and
costs charged by parent exceed revenues and costs as reported in the income
statement, for the period ended December 31, 1998, due to fiber optic network
assets to be transferred to the Company as described in note 1(b). The balance
as at December 31, 1999 of $7,297,000, is included in accounts payable.


    7.  SENIOR NOTES


    On July 28, 1999 the Company issued $500,000,000 12% senior notes (the
"Notes"). The Notes are unsecured obligations of the Company bearing interest at
12% payable semi-annually. The Notes are due August 1, 2009 and may be redeemed
by the Company on or after August 1, 2004 at certain specified redemption prices
ranging up to 106.00%. Up to 35% of the Notes may be redeemed by the Company
prior to August 1, 2002 at a redemption price of 112% of the principal amount
with the net proceeds from certain sales of the Company's common stock. If a
change in control occurs, as defined in the Notes indentures, the holders of the
Notes can require the Company to repurchase all or part of the Notes at 101% of
the principal amount. Where excess proceeds from certain asset sales, as defined
in the Notes indentures, exceeds $10,000,000 the Company is required to make an
offer to repurchase the maximum amount of Notes that can be repurchased with
such excess proceeds at an offer price equal to 100% of the principal amount.


    On December 23, 1998, the Company issued $175,000,000 12.5% senior notes
(the "1998 Notes"). The 1998 Notes are unsecured obligations of the Company
bearing interest at 12.5% payable semi-annually. The 1998 Notes are due
December 15, 2005 and may be redeemed by the Company on or after December 31,
2003 at certain specified redemption prices ranging up to 106.25% of the
principal amount. Up to 35% of the 1998 Notes may be redeemed by the Company
prior to December 15, 2001, at a redemption price of 112.5% of the principal
amount with the net proceeds from certain sales of the company's common equity
to the public. If a change of control occurs, as defined in the 1998 Notes
Indenture, the holders of the 1998 Notes can require the Company to repurchase
all or part of the 1998 Notes at 101% of the principal amount. If at the end of
December 31, 2000 and semi-annually thereafter, the Company's Accumulated Excess
Cash Flow, as defined in the 1998 Notes Indenture, exceeds $10,000,000, the
Company is required to make an offer to repurchase the maximum principal amounts
of 1998 Notes that may be purchased by such Accumulated Excess Cash Flow Amount
at an offer price equal to 110% of the principal amount of the 1998 Notes. Under
this Excess Cash Flow provision, the Company is not required to repurchase more
than 25% of the original principal amount of the 1998 Notes prior to
December 31, 2003.


    The Notes and 1998 Notes contain certain covenants that restrict the ability
of the Company and its subsidiaries to incur additional indebtedness and issue
certain preferred stock, pay dividends or make other distributions, repurchase
equity interests or subordinated indebtedness, engage in sale and leaseback
transactions, create certain liens, enter into certain transactions with

Shares to the holders of such shares pursuant to the terms of their original
purchase agreement dated September 7, 1999.



    The Series A Preferred Shares are entitled to dividends on an equivalent
basis to the Class A Non-Voting Shares into which the Series A Preferred Shares
can be converted. The Series A Preferred Shares rank senior to all classes of
capital stock upon liquidation, dissolution and wind-up and are junior in right
of payment of all indebtedness of the Company and its subsidiaries.



    The Series A Preferred Shares have a mandatory redemption on November 2,
2009 at a liquidation value consisting of the original purchase price of $2.43
per share plus an adjustment equal to 6% per annum of the purchase price, plus
declared and unpaid dividends and the excess of the market value of the Class A
Non-Voting Shares over the liquidation value.



    Upon a qualified underwritten public offering of at least $150,000,000 with
a share price of at least 300% of the purchase price of the Series A Preferred
Shares, each Series A Preferred Share may, at the option of the Company, be
converted into Class A Non-Voting Shares at a ratio equal to one plus 6% per
annum. If a qualified underwritten public offering occurs by September 9, 2000
the conversion will be on a one for one basis.



    The Series A Preferred Shares may be converted by the holders into Class A
Non-Voting Shares, at any time, on the same basis as the Company's conversion
right and may be converted into Series B Non-Voting Convertible Preferred Shares
on a one for one basis. In addition, the holders of the Series A Preferred
Shares have anti-dilution protection.



    SERIES B SUBORDINATE VOTING CONVERTIBLE PREFERRED SHARES



    The Series B Subordinate Voting Convertible Preferred Shares ("Series B
Preferred Shares) are entitled to dividends on an equivalent basis to any
dividends declared or paid on Class B Subordinate Voting Shares into which the
Series B Preferred Shares can be converted. The Series B Preferred Shares rank
senior to all classes of capital stock upon liquidation, dissolution and wind-up
and are junior in right of payment of all indebtedness of the Company and its
subsidiaries. The Series B Preferred Shares are entitled to one vote per share.



    The Series B Preferred Shares are mandatorily redeemable on November 2, 2009
at a liquidation value of $2.43 per share plus an adjustment equal to 6% per
annum of the purchase

the Class B Subordinate Voting Shares over the liquidation value.

a share price of at least 300% of the purchase price of the Series B Preferred
Shares, each Series B Preferred Share, may at the option of the Company, be
converted into Class B Subordinate Voting Shares at a ratio equal to one plus 6%
per annum. If a qualified underwritten public offering occurs by September 9,
2000 the conversion will be on a one for one basis.

    The Series B Preferred Shares may be converted into Class B Subordinate
Voting Shares, at any time on the same basis as the Company's conversion right
and may be converted into Series A Preferred Shares on a one for one basis. In
addition, the holders of the Series B Preferred Shares have anti-dilution
protection

    SERIES C REDEEMABLE PREFERRED SHARES


    On September 9, 1999, 80,000,000 Series C Redeemable Preferred Shares
("Series C Preferred Shares") were issued pursuant to a stock dividend and

Series C Preferred Shares for $45,000,000 (note 9). The holders of Series C
Preferred Shares are not entitled to dividends or voting rights and may redeem
the Series C Preferred Shares at $1 per share after November 2, 2009.


    9.  CAPITAL STOCK


    On September 9, 1999 the Company authorized various classes of capital stock
(see "Share capital transactions").

Shares, and Class C Multiple Voting Shares participate equally in dividends
declared subject to any preference priority on other classes of shares.



    The holders of the Class A Non-Voting Shares are not entitled to voting
rights. The holders of Class B Subordinate Voting Shares are entitled to one
vote per share, and the holders of Class C Multiple Voting Shares are entitled

share to the holders of the three classes of capital stock.


    The holders of Class A Non-Voting Shares are entitled to convert their
Shares to Class B Subordinate Voting Shares on a one for one basis. The holders
of Class B Subordinate Voting Shares are entitled to convert their Shares to
Class A Non-Voting Shares on a one for one basis at any time prior to
September 9, 2000 and into Series A Preferred Shares on a one for one basis. The
holders of Class C Multiple Voting Shares are entitled to convert their Shares
into Class A Non-Voting Shares or Class B Subordinate Voting Shares on a one for

RESTRICTED STOCK AND OTHER STOCK ISSUANCES



    During the year, the Company issued stock to certain directors and officers
of the Company. To the extent that these stock issuances are considered to be
below fair value, stock based compensation is recognized and amortized over the
appropriate periods. The Company recognized $176,164,000 of deferred stock-based
compensation related to stock issued to these officers and directors in 1999 of
which $2,832,000 was expensed in the year.



    The shares issued to the executive officer are subject to a repurchase by
the Company at the lesser of fair market value of the shares and the original
purchase price of the shares plus interest. The restriction lapsed with respect
to 15,500,000 shares immediately on commencement of employment and lapses for
12,400,000 shares in 2000, 13,639,968 shares in 2001 and 2002 and the remainder
in 2003. Under certain conditions, the executive officer may put back a certain
number of shares to the Company, or at the option of the Company to Worldwide
Fiber Holdings Ltd., at fair market value to repay the promissory note. Deferred
compensation related to these shares will be amortized over the periods covered
by the repurchase restriction.

</TABLE>



    Management believes that, based on a number of factors, it is more likely
than not that the deferred tax asset will be fully utilized, such that no
valuation allowance has been recorded.



    12.  CONCENTRATION OF CREDIT RISK


    Financial instruments that potentially subject the Company to a significant
concentration of credit risk consist primarily of cash and cash equivalents,
short-term investments, accounts receivable, unbilled revenue and due from
parent which are not collateralized. The Company limits its exposure to credit
loss by placing its cash and cash equivalents and short-term investments with
high credit quality financial institutions. Concentrations of credit risk with
respect to accounts receivable and unbilled revenue are considered to be limited
due to the credit quality of the customers comprising the Company's customer
base.


    The Company performs ongoing credit evaluations of its customers' financial
condition to determine the need for an allowance for doubtful accounts. The
Company has not experienced significant credit losses to date. Accounts
receivable was comprised of 22 customers at December 31, 1999 and 12 customers
at December 31, 1998.



    The concentration of credit risk relating to the amount due from the parent
is considered limited due to the credit quality of the Company's parent. The
Company's three largest customers represented 22%, 15% and 10% of the Company's
total revenue for 1999. As described in Note 1, substantially all of the
Company's revenues during the period ended December 31, 1998 were earned from
construction services provided to Ledcor.

1.  THE COMPANY

    Worldwide Fiber (USA), Inc. (the "Company"), was incorporated on August 7,
1998. The Company was inactive until August 31, 1998. On August 31, 1998, the
Company acquired 100% of the ownership interest of Worldwide Fiber
Networks, Inc. ("WFNI") from its two members, Ledcor Industries Limited
("Ledcor") and Mi-Tech Communications, LLC ("Mi-Tech"), in exchange for 100
non-voting common Shares and 100 Class A voting preferred Shares of the Company.
The acquisition was accounted for in a manner similar to a pooling of interests
on the basis that the ownership interests before and after the acquisition
remained the same. Accordingly, the financial statements presented include the
results of operations of the Company and WFNI from February 11, 1998, the date
that WFNI was organized.

    On December 31, 1998, the Company issued 100 Shares of non-voting common
Shares and 100 Class A voting preferred Shares as consideration for the
settlement of indebtedness owed to Worldwide Fiber Inc. ("WFI" or "parent") of
$3,915,000 increasing WFI's interest from 50% to 75%.

    The Company has entered into a shareholders' agreement among WFI, Ledcor,
Mi-Tech and Michels Pipeline Construction Inc. (an affiliate of Mi-Tech)
whereby:

    (i)  Any sale, transfer, assignment or encumbrance or divestment of any
       interest in or control of the Company to a third party is restricted. In
       the event of a proposed sale of the Shares of the Company held by WFI,
       Mi-Tech will have certain tag-along rights. If there is a change of
       control of the Company, Mi-Tech has the option to require the Company to
       purchase all of the Shares owned by Mi-Tech or its affiliates at the fair
       market value of such Shares. In addition, after the tenth anniversary of
       this agreement Mi-Tech has the option to require the Company to purchase
       all of the Shares owned by Mi-Tech and its affiliates at fair market
       value. If Mi-Tech exercises this option, WFI can elect to sell all of the
       Shares or assets of the Company to a third party in which case WFI will
       not be required to purchase Mi-Tech's Shares.

    (ii) The Company has an option to purchase from Mi-Tech, 24 fiber optic
       strands along certain existing routes owned by Mi-Tech and its affiliates
       at fair value. The Company also has an option to purchase from WFI and
       its affiliates indefeasible rights of use for 24 fiber optic strands from
       its Chicago-New Orleans route if and when built, at fair value. These
       options expire one year after the strands are available.

    (iii) If WFI were to issue Shares in a public offering having an aggregate
       value of at least $20,000,000, Mi-Tech has the option to convert all of
       the Shares of the Company held by Mi-Tech and its affiliates into the
       class and series of Shares being offered to the public.

    The Company's operations consist of developing, engineering, constructing,
installing and maintaining fiber optic network assets. The Company's primary
customers are telecommunications carriers and fiber optic systems developers
located in the U.S.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                               DECEMBER 31, 1998
            (TABULAR AMOUNTS EXPRESSED IN THOUSANDS OF U.S. DOLLARS)

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    BASIS OF PRESENTATION

    These consolidated financial statements have been prepared in accordance
with generally accepted accounting principles in the United States and include
the accounts of the Company and its wholly-owned subsidiaries. All significant
intercompany transactions and balances have been eliminated on consolidation.

    The Company's financial statements have been prepared for inclusion within
the Offering Memorandum prepared by WFI for the offer of Senior Notes in the
amount of $250,000,000. The consolidated balance sheet of the Company as at
December 31, 1998 has been excluded as WFI's most recent audited consolidated
balance sheet includes the assets and liabilities of the Company.

    USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions which affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and revenues and expenses for the period reported. Actual results
could differ from those estimates.

    INCOME TAXES

    Income taxes are accounted for using an asset and liability approach, which
requires the recognition of taxes payable or refundable for the current period
and deferred tax liabilities and assets for future tax consequences of events
that have been recognized in the Company's financial statements or tax returns.
The measurement of current and deferred tax liabilities and assets are based on
provisions of enacted tax laws; the effects of future changes in tax laws or
rates are not anticipated. The measurement of deferred tax assets is reduced, if
necessary, by a valuation allowance, where, based on available evidence, the
probability of realization of the deferred tax asset, does not meet a more
likely than not criteria.

    REVENUE RECOGNITION

    Revenue and income from construction contracts to develop fiber optic
network assets, are determined on the percentage-of-completion basis using the
cost-to-cost method. Provision is made for all anticipated losses as soon as
they become evident. Claims for additional contract compensation are not
recognized until resolved.

    FOREIGN CURRENCY TRANSACTIONS

    The Company uses the U.S. dollar as its functional currency. Gains or losses
from foreign currency transactions are included in the consolidated income
statement.

                                                                $980
                                                                ====
</TABLE>

    The Company's statutory rate of 34% is not materially different to its
effective rate of 34.6%.

6.  CONCENTRATION OF CREDIT RISK

    Financial instruments that potentially subject the Company to a significant
concentration of credit risk consist primarily of cash and cash equivalents,
accounts receivable and unbilled revenue. Accounts receivable are not
collateralized. The Company limits its exposure to credit loss by placing its
cash and cash equivalents with high credit quality financial institutions.
Concentrations of credit risk with respect to accounts receivable and unbilled
revenue are considered to be limited due to the credit quality of the customers
comprising the Company's customer base.

    The Company performs ongoing credit evaluations of its customers' financial
condition to determine the need for an allowance for doubtful accounts. The
Company has not experienced significant credit losses to date. At December 31,
1998 seven customers accounted for the entire accounts receivable and unbilled
revenue balances.

7.  REVENUE AND SIGNIFICANT CUSTOMERS

    During the period ended December 31, 1998, the Company's revenue from its
three largest customers represented individually 35%, 30% and 13% of total
revenue.

8.  RELATED PARTY TRANSACTIONS

    The Company reimburses Ledcor and Mi-Tech for expenses incurred on the
Company's behalf. For the period ended December 31, 1998 the amount of these
transactions with Ledcor and Mi-Tech was $1,469,000 and $1,401,000 respectively.
As at December 31, 1998 accounts payable includes $478,000 owed to Ledcor and
$524,000 owed to Mi-Tech.

9.  SEGMENTED INFORMATION

    The Company operates within a single operating segment being the
construction and installation of fiber optic network assets in the United
States. All revenues are earned from U.S. sources and all long-lived assets are
located in the U.S.

10.  COMMITMENTS

To the Directors of
Ledcor Industries Limited


    We have audited the divisional balance sheet of Ledcor Industries Limited--
Telecommunications Division as at May 31, 1998 and the divisional statements of
operations and retained earnings and cash flows for the nine months ended
May 31, 1998 and year ended August 31, 1997. These financial statements are the
responsibility of the Division'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 an audit to obtain
reasonable assurance 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.


    In our opinion, these divisional financial statements present fairly, in all
material respects, the financial position of the Division as at May 31, 1998 and
the results of its operations and cash flows for the periods ended May 31, 1998
and August 31, 1997 in accordance with generally accepted accounting principles

                  NOTES TO THE DIVISIONAL FINANCIAL STATEMENTS

                       (ALL FIGURES ARE IN U.S. DOLLARS)

1.  DESCRIPTION OF BUSINESS

    The Telecommunications Division (the "Division") is a division of Ledcor
Industries Limited ("LIL") which, in turn, is a wholly-owned subsidiary of
Ledcor Inc. The Division is in the business of providing long-haul fiber optic
systems, including planning, design, construction and maintenance to
telecommunications clients. The Division headquarters are in Vancouver, Canada
and its principal geographic areas of operation for these fiber optic systems
are Canada and the United States.

    The accompanying divisional financial statements include the assets,
liabilities, revenues and expenses of the Division. Since the Division has been
operating as a fully integrated part of the Company, all construction equipment
owned by LIL, but used in the Division's operations, was identified by LIL's
management and allocated to the Division. In addition, certain assets,
liabilities, revenues and expenses have been recorded by the Division using
management's best estimates (Note 3).

    The divisional financial statements have been prepared from the divisional
records maintained by LIL and may not necessarily be indicative of the
conditions that would have existed or the results of operations if the Division
had been operated as a stand-alone company.

    The Division does not hold any cash or cash equivalents. LIL uses central
bank accounts to deposit receipts and make payments on behalf of the Division.
These transactions are reflected in the inter-divisional account (Note 8).

    On May 31, 1998, LIL transferred the net assets (at book value) and the
operations of the Division to Worldwide Fiber Inc. (indirectly a wholly-owned
subsidiary of Ledcor Inc.).

2.  ACCOUNTING POLICIES

    A)    BASIS OF ACCOUNTING


    These divisional financial statements have been prepared in accordance with
    accounting principles generally accepted in the United States.


    B)    ACCOUNTING FOR CONTRACTS

    Revenue and income from construction contracts to develop fiber optic
    systems are determined on the percentage of completion basis using the
    cost-to-cost method. Due to the risks inherent in these contracts,
    management makes a provision for risk using their best estimate. This method
    is used because management considers costs incurred to be the best available
    measure of progress on these contracts. Provision is made for all
    anticipated losses as soon as they become evident. Claims for additional
    contract compensation are not recognized until resolved.

    C)    UNBILLED REVENUE

    Unbilled revenue comprises costs incurred and margin in excess of billings
    and advance deposits, representing unperformed work, on uncompleted
    contracts.

    D)    INVENTORY

    Inventory consists of fiber optic strands under construction and is valued
    at the lower of cost or market. Cost is determined using the full absorption
    method whereby the fiber optic strands have been allocated their
    proportionate share of materials, labour and overhead incurred.

            NOTES TO THE DIVISIONAL FINANCIAL STATEMENTS (CONTINUED)

                       (ALL FIGURES ARE IN U.S. DOLLARS)

    E)    FIXED ASSETS

    Construction equipment, fiber optic strands and other assets are recorded at
    cost. Fixed assets are depreciated using the following rates and methods:

    - Construction equipment--hourly usage rates, estimated to depreciate the
      equipment, over estimated useful lives, ranging from three to five years.

    - Fiber optic strands, under construction--depreciation, at appropriate
      rates, will be provided for when the related fiber optic systems are in
      use.

    - Other assets-straight--line method over the estimated useful lives of the
      assets, ranging from three to five years.

    F)    INCOME TAXES

    These are the financial statements of a Division, and not of a taxable legal
    entity. However, these financial statements present income taxes as if the
    Division was a stand-alone taxable legal entity. Current and deferred income
    taxes have been determined by applying the asset and liability method.

    The asset and liability method of accounting for income taxes recognizes
    deferred tax assets and liabilities for the future tax consequences
    attributable to temporary differences between the financial statement
    carrying amounts of existing assets and liabilities and their respective tax
    bases. Deferred tax assets and liabilities are measured using enacted tax
    rates expected to apply to taxable income in the years in which those
    temporary differences are expected to be recovered or settled.

    G)    TRANSLATION OF FOREIGN CURRENCY

    The functional currency of the Division is the Canadian dollar. The
    financial statements are translated into United States dollars using the
    period end exchange rate for assets and liabilities and weighted average
    exchange rates for the period for revenues and expenses. Translation gains
    and losses are deferred and included in divisional equity. Net gains and
    losses resulting from foreign exchange transactions are included in the
    statement of operations.

3.  USE OF ESTIMATES IN THE FINANCIAL STATEMENTS

    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 at
    the dates of the divisional financial statements and the reported amounts of
    revenues and expenses during the reporting periods. Actual results could
    differ from those estimates.

    Unbilled revenue, inventory, fiber optic strands capitalized, and revenue
    have all been calculated using management's best estimates. Total estimated
    costs is a component of the percentage of completion calculation which
    determines revenue recognized, unbilled revenue, inventory and fiber optic
    strands capitalized. However, there may be unforeseen conditions which could
    include weather patterns, the continuing deterioration of the Canadian
    dollar, and the outcome of ongoing negotiations. Such conditions could
    substantially change the values of the above mentioned items reflected in
    these financial statements. The impact of these unforeseen conditions cannot
    be estimated by management as at May 31, 1998.

             LEDCOR INDUSTRIES LIMITED--TELECOMMUNICATIONS DIVISION

            NOTES TO THE DIVISIONAL FINANCIAL STATEMENTS (CONTINUED)

                       (ALL FIGURES ARE IN U.S. DOLLARS)

    Corporate expenses are allocated from LIL to the Division based on a
percentage of the Division's revenue. Management is of the opinion that this
allocation percentage is reasonable since all divisions fully absorb LIL's
corporate expenses. Management regularly reviews this allocation basis and
considers the amounts allocated to fairly represent actual corporate expenses
incurred, on behalf of the Division, for the periods reported on. Because the
Division is fully integrated, management is unable to estimate the actual
corporate expenses that would have been incurred if the Division had operated on
a stand-alone basis.

    Interest is allocated from LIL by charging a floating rate of prime plus 1%
on the net cash position of the Division's projects at the end of each month.
Statement of Financial Accounting Standards No. 34, "Capitalization of Interest
Cost", requires that interest be capitalized as part of the historical cost of
constructing assets held for sale or lease. Management has capitalized interest
by capitalizing the portion of interest costs incurred to date which relates to
inventory and capital assets.

    The Division has no additional debt accruing interest which should be
capitalized. In addition, LIL has no additional debt which would result in
significant interest being allocated and capitalized.

4.  TRADE ACCOUNTS RECEIVABLE AND ACCOUNTS RECEIVABLE HOLDBACKS

    Trade accounts receivable are presented net of the allowance for doubtful
accounts (which was nil for all years reported on since the Division has not
experienced any bad debts).

    Accounts receivable holdbacks represent amounts billed but not yet paid
under retainage provisions in the project contracts. These provisions state that
holdbacks will be collected upon substantial completion of the projects.

5.  UNBILLED REVENUE

    Costs and billings on uncompleted contracts included in the divisional
financial statements are as follows:

    The Division's provision for deferred taxes approximates the amounts
computed by applying the Canadian and United States statutory rates to income
before taxes. There are no permanent differences or other reconciling items that
would result in an effective tax rate which is different from the statutory
rates applied.

9.  COMMITMENTS

    A)    FIBER OPTIC CONSTRUCTION PROJECT

    In 1996, the Division commenced construction of a Canadian-U.S. fiber optic
    telecommunications system (the Canadian FOTS) that is scheduled for
    completion in early 1999.

    B)    FONOROLA CONTRACT

    In a variety of contracts, commencing in April, 1997, the Division sold
    fiber optic strands of the Canadian FOTS. The Division has a commitment to
    complete construction of the fiber optic strands.

    C)    BELL CANADA CONTRACT

    In February, 1998, the Division sold fiber optic strands of the Canadian
    FOTS. The Division has a commitment to complete construction of the fiber
    optic strands.

    D)    METRONET CONTRACT

    Subsequent to period end (September, 1998), the Division sold fiber optic
    strands of the Canadian FOTS. The Division has a commitment to complete
    construction of the fiber optic strands.

    E)    LEASE COMMITMENTS

    The Division is committed under non-cancellable leases for equipment for the
    period ending April, 1999 in the amount of $826,271. The Division has an

                       (ALL FIGURES ARE IN U.S. DOLLARS)

    The Division also had significant accounts receivable from FONOROLAwhich
accounted for the following percentages of trade accounts receivable:


<TABLE>
<CAPTION>
                                                              MAY 31, 1998

FONOROLA....................................................       39%
</TABLE>


    The Division is receiving cash from this customer on a consistent basis and
management expects to collect on all other accounts receivables. Therefore no
provision for bad debts has been recorded for the reported periods. Based on
this significant customer's creditworthiness, the Division has not required it
to provide collateral against these receivables.

    There were no significant accounts payable to significant suppliers at the
balance sheet dates. However, since significant purchases are made from Pirelli
Cables, should this supplier fail to honor its contract and the Division was not
able to find a substitute supplier, the Division would not be able to meet its
commitments to complete the construction of the Canadian FOTS, as noted in 9(a).

11.  FINANCIAL INSTRUMENTS

    Financial instruments consist of recorded accounts receivables (and other
like accounts) which will result in future cash receipts, as well as accounts
payables, (and other like accounts) that will result in future cash outlays.


    The carrying values of the financial instruments of the Division as at
May 31, 1998 were approximately equal to their estimated fair market values at
these dates, due to the short-term nature of these instruments. Subjective
judgment and uncertainties arise in the determination of estimated fair market
values. Accordingly, the aggregate fair value should not be interpreted as being
realizable in an immediate settlement of the instruments.


12.  INDUSTRY AND GEOGRAPHIC AREA SEGMENT INFORMATION

    The Division currently operates in one industry segment (fiber optic
installations) and in two geographic segments (the Canadian FOTS is being
constructed in Canada and the U.S.). Revenue and total identifiable assets for
these geographic segments is as follows:

13.  UNCERTAINTY DUE TO THE YEAR 2000 ISSUE

    The Year 2000 Issue arises because many computerized systems use two digits
rather than four to identify a year. Date-sensitive systems may recognize the
year 2000 as 1900 or some other date, resulting in errors when information using
year 2000 dates is processed. In addition, similar problems may arise in some
systems which use certain dates in 1999 to represent something other than a
date. The effects of the Year 2000 Issue may be experienced before, on, or
after, January 1,

2000 and, if not addressed, the impact on operations and financial reporting may
range from minor errors to significant systems failure which could affect the
Division's ability to conduct normal business operations. It is not possible to
be certain that all aspects of the Year 2000 Issue affecting the Division,
including those related to the efforts of customers, suppliers, or other third
parties, will be fully resolved.

14.  SUBSEQUENT EVENTS

    A) AGREEMENTS WITH WFI

    Effective May 31 1998, LIL entered into a series of agreements to sell the
equipment, fiber optic strands and certain other assets related to the business
of Worldwide Fiber Inc. (an indirect wholly-owned subsidiary of Ledcor Inc.)
("WFI"). In addition, WFI was granted a licence by LIL to use certain processes
related to the business. This licence agreement is for an initial term of ten
years and will be renewable annually upon completion of the initial term. As
part of this transaction, LIL retained all existing construction contracts
related to the business. This transaction was between entities under common
control and has been accounted for using the carrying amounts recorded in LIL's
accounts. As consideration for the transaction, LIL was issued 200 Class A
Shares by WFI.

    B)    DISPOSITION OF FIBER ASSETS

    As part of these agreements WFI undertook to purchase from LIL certain fiber
optic system assets, located in both Canada and the U.S., which were not
completed at May 31, 1998. These assets will be purchased by WFI upon their
completion, which is estimated to be late 1998 or early 1999. As consideration,
WFI will issue a total of 19,999,700 Class A common Shares to LIL. These
transactions are between entities under common control and, will be accounted
for at their original construction costs.

    C)    CONSTRUCTION SERVICES

        WFI has agreed to provide construction services to LIL to complete
    certain construction contracts for fiber optic strands and related
    facilities to third party customers.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



              FOR THE YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997



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



1 NATURE OF OPERATIONS



    GlobeNet Communications Group Limited provides international
telecommunications services to both residential and commercial customers and is
a provider of telecommunications capacity. The Company is currently developing a
fibre optic submarine cable system called Atlantica-1 that will link Bermuda,
North and South America and offer capacity between major cities in the United
States, Bermuda, Brazil, Venezuela and Argentina. Atlantica-1 is currently being
constructed.



    In November 1997, the Company deployed a fibre optic submarine cable system
which connects Bermuda and the United States ("BUS-1"). The Company provides
international telecommunications services to both residential and commercial
customers in Bermuda through a subsidiary company, TeleBermuda International
Limited ("TBI") through the BUS-1.



    On January 10, 1997, TBI was granted its public telecommunications service
licence in Bermuda under the provisions of the Telecommunications Act, 1986 and
the Public Telecommunication Service (Licence) Regulations, 1988 for a five-year
term and began commercial operations in May 1997. TBI has an interconnection
agreement with the Bermuda Telephone Company ("BTC"), the domestic carrier in
Bermuda. No consideration was paid by the Company in relation to these
agreements.



2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES



    These consolidated financial statements are prepared in accordance with
accounting principles generally accepted in the United States. The following is
a summary of the significant accounting policies followed in the preparation of
these consolidated financial statements.



PRINCIPLES OF CONSOLIDATION



    The consolidated financial statements include the accounts of the Company
and all of its subsidiary companies. Intercompany accounts and transactions have
been eliminated on consolidation.



USE OF SIGNIFICANT ACCOUNTING ESTIMATES



    The preparation of financial statements in conformity with generally
accepted accounting principles in the United States requires management to make
estimates and assumptions that affect the reported amounts of assets and

REVENUE, DEFERRED REVENUE AND COST RECOGNITION



    REVENUE:  The Company provides telecommunication services and the granting
or leasing of indefeasible rights of use ("IRU") interests in its
telecommunications infrastructure.



    The Company records as revenue the amount of telecommunications services
rendered, as measured primarily by the minutes of traffic processed, after
deducting an estimate of the traffic for

which revenue will not be collected. Historical deductions have not been
material. Service discounts and incentives are accounted for as a reduction of
revenue when granted, or where provided in relation to a service contract,
rateably over the contract period.



    The Company has entered into certain IRU agreements. Such agreements are
accounted for as either service or lease transactions. Those IRU agreements that
meet all of the following characteristics have been accounted for as leases:



    (a) The purchaser has exclusive right to the purchased capacity for a
       specified period, generally the estimated useful life of the system,
       which is 25 years.



    (b) The Company cannot sell or otherwise use any of the purchaser's unused
       capacity for the term of the agreement.



    (c) The purchased capacity is physically limited to discrete channels on the
       purchaser's own dedicated circuits at a specified amount of capacity,
       which cannot be exceeded. The specific circuits are agreed to by the
       parties.



    (d) The Company has no right to move the purchased capacity to another
       discrete channel from the purchaser's dedicated circuits without the
       purchaser's permission.



    IRU agreements that meet these criteria are accounted for as lease
transactions. If the transactions meet the sales type lease criteria of
Financial Accounting Standard No. 13, including those related to collectibility
of the payments and the absence of any important uncertainties surrounding
unreimbursable costs yet to be incurred by the Company, then revenue is
recognized in the period that the IRUs are transferred and the capacity is
available for service. If these criteria are not met, the transactions are
accounted for as operating leases and revenue is recognized over the term of the
lease.



    To date, the Company has not entered into any IRU agreements that are
considered to be service transactions. Revenue from service transactions would
be recognized as earned over the term of the agreement.



    In addition, we note that the accounting for sales of capacity is evolving,
and is currently under consideration by accounting standard setters. Any change
in accounting literature may affect the timing and method of recognition of
these revenues and related costs.



    Revenues from private line services are recognized as earned.



    DEFERRED REVENUE:  Rent from the operating leases of capacity in the
telecommunications infrastructure to third party carriers is deferred and
recognized over the term of the lease on a straight-line basis. Revenue from the
sale of prepaid calling cards is recognized as the services are provided.



    COST:  Carrier charges are comprised primarily of local access charges and
international termination costs. These costs are recognized based on traffic
volume.

FIXED ASSETS



    Fixed assets are recorded at cost less accumulated amortization.
Amortization commences when an asset is available for use, and is calculated in
a systematic manner based on the expected useful lives of the assets as follows:

</TABLE>



CONSTRUCTION IN PROGRESS



    Construction in progress includes direct expenditures for the construction
of the Company's Atlantica-1 project and is stated at cost. Costs are
capitalized once it is probable that the fibre optic cable system will be
constructed, otherwise they are expensed as incurred. Capitalized costs include
costs incurred under the construction contract, advisory, consulting and legal
fees and interest.



DEFERRED FINANCING COSTS



    Deferred financing costs represent debt issuance costs, which are amortized
over the estimated term of the related debt.



INVESTMENTS



    The Company's investments are accounted for using the equity method.



FOREIGN CURRENCY TRANSLATION



    Monetary assets and liabilities denominated in foreign currencies are
translated into U.S. dollars at exchange rates prevailing at the balance sheet
date. Revenues and expenses are translated into U.S. dollars at the average
rates of exchange prevailing at the dates of the respective transactions.
Transactions are translated into U.S. dollars at the exchange rates in effect at
the time the transactions occur. Exchange gains and losses arising on
translation are included in the operating results for the year.



    Assets and liabilities of non-Bermudian subsidiaries where the functional
currency is other than the U.S. dollar are translated at the exchange rate in
effect at the balance sheet date. Revenues and expenses are translated at
average exchange rates prevailing during the year.

2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)


FINANCIAL INSTRUMENTS



    The fair value of financial assets and liabilities represents the amount at
which these instruments could be exchanged in an arm's length transaction
between willing parties.



    As at December 31, 1999, the carrying amounts of financial assets and
liabilities in the consolidated balance sheet approximate their fair values due
to the short-term nature of these instruments.



    The reported amount of fixed rate long-term debt instruments is estimated to
approximate fair value as actual rates are consistent with rates estimated to be
currently available for debt of similar terms and remaining maturities.



    In addition, the Company has entered into an interest rate cap agreement to
modify the interest characteristics of part of its outstanding long-term debt.
This agreement involves an exchange of amounts based on a fixed interest rate
for amounts based on a variable interest rate whenever the interest rate exceeds
the cap specified in the agreement. The premium paid by the Company upon
entering in the agreement is amortized over the term of the agreement and
recognized as an adjustment of interest expense related to the debt. The Company
does not use derivative financial instruments for speculative trading purposes.
As of December 31, 1999, the carrying value approximates fair value.



INCOME TAXES



    Under current Bermuda laws, the Company is not required to pay any taxes in
Bermuda on either income or capital gains. The Company has received an
undertaking from the Minister of Finance in Bermuda, pursuant to the Exempted
Undertakings Tax Protection Act 1966, which exempts the Company from any such
tax until March 28, 2016. Subsidiaries in other jurisdictions are subject to
local taxes.



STOCK BASED COMPENSATION



    The Company applies APB Opinion 25 ("Accounting for Stock Issued to
Employees") in accounting for its stock option plan, and, accordingly, does not
recognize compensation cost at the time options are granted unless the exercise
price is less than the market price of the stock on the measurement date.



RECENT ACCOUNTING PRONOUNCEMENTS



    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133
("SFAS 133"), "Accounting for Derivative Instruments and Hedging Activities"
which is effective for fiscal years beginning after June 15, 2000. SFAS 133, as
amended, requires the Company to recognize all derivatives as either assets or
liabilities and measure those instruments at fair value. It further provides
criteria for derivative instruments to be designated as fair value, cash flow,
and foreign currency hedges and establishes respective accounting standards for
reporting changes in the fair value of the derivative instruments. Upon
adoption, the Company will be required to adjust hedging

instruments to fair value in the balance sheet and recognize the offsetting
gains or losses as adjustments to be reported in net income or other
comprehensive income, as appropriate. Management has not determined the impact
of this statement on its financial position, results of operations and cash
flows.



    FASB Interpretation No. 43, "Real Estate Sales--an interpretation of FASB
Statement No. 66," was issued in June 1999. It clarifies the standards for
recognition of profit on all real estate sales transactions, including those
related to fibre optic cable that cannot be removed and used separately from the
real estate without incurring significant costs. This interpretation is
effective for all applicable transactions after June 30, 1999. However, no such
transactions have been entered into after June 30, 1999 and we have not yet
completed our analysis of the applicability or the impact of this statement on
future transactions.

10 GRANTING OF INDEFEASIBLE RIGHTS OF USE AND LEASING OF THE FIBRE OPTIC
SUBMARINE CABLE (CONTINUED)


    recognized with the granting of the IRUs are calculated as total capacity
    granted in relation to the total cost of the activated fibre optic submarine
    cable times the total cost of the fibre optic submarine cable system. In
    addition, under these IRU agreements, the third party carrier is responsible
    for paying its pro rata share of restoration costs. These costs are
    accounted for as expenses as they are incurred, less a recovery of expense
    being recorded to reflect the required pro rata reimbursement from the IRU
    customer.



b)  The Company has entered into an agreement to provide capacity in its fibre
    optic submarine cable to a third party. This arrangement is being accounted
    for as an operating lease. The term of the lease is for the greater of 25
    years or the operational life of the fibre optic submarine cable. If the
    operational life is less than 10 years, the Company must provide a refund on
    a pro rata basis for each year short of the 10-year period. For the first
    four years of the agreement, the Company is responsible for maintenance and
    operating costs, thereafter the lessee will pay a monthly charge for
    operating and maintenance costs. The total rental payment for this agreement
    was $8,000, of which $4,000 was paid in 1999 and $3,000 in 1998. The
    remaining payment of $1,000 is due on September 24, 2000. Lease income is
    being recognized on a straight-line basis over the 25-year term. During
    1999, lease income of $315 (1998--$263; 1997--$nil) was recognized.



    Under this agreement, the third party has the right to enter into a second
lease of capacity in the fibre optic submarine cable commencing September 24,
2001. The consideration for the second lease will be $4,000 payable upon
activation of the second circuit. If the third party elects not to proceed with
the second lease a penalty of $250 is payable to the Company.

    i)  On December 18, 1998 and May 21, 1999, the Board of Directors issued
       263,000 options and 5,000 options, respectively to employees and certain
       officers and directors at an exercise price of $9.00 per option, vesting
       over a three-year period, under the 1998 Share Option and Incentive Plan.
       In July 1999, when these options were approved by the shareholders, the
       market price of these options was $20.40. The difference between the
       market price and the exercise price has been reflected as deferred
       compensation in the statement of shareholders' equity and is being
       amortized over the vesting period as at December 31, 1999. Compensation
       expense in the amount of $1,794 has been recorded in the financial
       statements.



       On July 9, 1999, 35,000 options, with an exercise price of $19.00 with a
       ten-year term were granted to certain directors. The market price of
       these options on the measurement date was $20.40. The vesting of these
       options occurred on July 14, 1999. The difference between the exercise
       price and market price at the time of vesting amounted to $49 and has
       been reflected as compensation expense.



       On April 12, 1999, the Company granted 540,000 options at an exercise
       price of $9.00 with a ten-year term to certain officers and directors.
       These options vest in three separate tranches based upon the Company
       meeting certain milestones related to the Atlantica-1 project. On
       July 14, 1999, the first vesting milestone occurred on 165,000 of these
       options, when the financing was secured and the vesting period for
       another 165,000 options was determined. The difference between the
       exercise price and the market value amortized over the vesting period
       amounted to $2,364 and has been reflected as compensation expense.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)



              FOR THE YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997



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



13 COMMON SHARE OPTIONS (CONTINUED)


       On October 7, 1999, the Company granted 429,019 options at an exercise
       price of $20.40 to certain officers. Of these options, 129,019 vest
       immediately and 300,000 vest over three years although vesting on these
       options may be accelerated as a result of certain events.



       On October 22, 1999, the Company granted 5,000 options at an exercise
       price of $19.00 to an employee. These options vest over three years.



    Total stock-based compensation expense included in general and
administrative expenses for the year ended December 31, 1999 is $4,207
(1998--$nil; 1997--$nil).



    Had the Company elected to recognize compensation cost based on the fair
value of the options granted at the grant date as prescribed by SFAS 123, the
pro forma effects to reported net loss for the year and basic and fully diluted
loss per common share, would be as follows:

Net loss for the year--as reported..........................   15,906     4,944      5,296
Net loss for the year--pro forma............................   15,906     5,047      5,296
Basic and fully diluted loss per common share--as
  reported..................................................     1.60      1.41       1.52
Basic and fully diluted loss per common share--pro forma....     1.60      1.43       1.52
</TABLE>



    The fair value of each option grant has been estimated using the
Black-Scholes option pricing model, using a volatility assumption of 20%
(1998--20%; 1997--20%), expected life of 7 years (1998--7 years; 1997 -7 years),
a dividend rate of nil (1998--$nil; 1997--$nil) and a risk-free interest rate of
5.64% (1998--5.28%; 1997--6.33%).



    The above pro forma effects on the net loss for the year may not be
representative of the effects on the net loss for the year for future periods as
option grants typically vest over several years and additional options are
generally granted each year.



14 BASIC AND FULLY DILUTED LOSS PER COMMON SHARE



    The basic loss per common share is calculated using the weighted average
number of common shares outstanding of 9,911,341 (1998--3,515,927;
1997--3,492,915). The weighted average number of common shares on a fully
diluted basis is calculated on the same basis as the basic weighted average
number of shares as the Company is in a loss position and the effects of
possible conversion would be anti-dilutive.

and Exchange Commission. The offering price of the Subordinate Voting Shares
will be determined by negotiation between the Company and Goldman, Sachs & Co.,
Donaldson, Lufkin & Jenrette Securities Corporation, Credit Suisse First Boston
Corporation, TD Securities Inc., Bear, Stearns & Co. Inc., BMO Nesbitt
Burns Inc., Morgan Stanley & Co. Incorporated, Hambrecht & Quist LLC, RBC
Dominion Securities Inc. and Warburg Dillon Read LLC (collectively, the
"Underwriters"). The Subordinate Voting Shares are being offered in Canada by
Goldman Sachs Canada Inc., Credit Suisse First Boston Securities Canada Inc., TD
Securities Inc., BMO Nesbitt Burns Inc., Morgan Stanley Canada Limited, Bunting
Warburg Dillon Read Inc. and RBC Dominion Securities Inc. (collectively, the
"Canadian Underwriters").

    THERE IS CURRENTLY NO MARKET THROUGH WHICH THE SUBORDINATE VOTING SHARES MAY
BE SOLD. The offering price of each Subordinate Voting Share, after giving
effect to this offering, but before exercise of the Underwriters' over-allotment
option, exceeds the Company's consolidated net tangible book value as of   -  ,
2000 by U.S.$  -  , resulting in a dilution of   -  %. See "Dilution". AN
INVESTMENT IN SUBORDINATE VOTING SHARES IS SUBJECT TO A NUMBER OF RISK FACTORS
WHICH SHOULD BE CAREFULLY REVIEWED BY PROSPECTIVE PURCHASERS. SEE "RISK
FACTORS".

                                  RISK FACTORS

    Investment in the Company's Subordinate Voting Shares is subject to a number
of risk factors that prospective investors should carefully consider. These risk
factors include: the Company's limited history of operations; risks associated
with development and expansion of the Company's network; risk that network
failure or disruptions could adversely affect the Company's operating results;
the Company's limited experience in offering bandwidth and value added network
services; risk that prices for the Company's network services and fiber assets
will decline; the need to obtain additional rights-of-way; risks associated with
the Company's joint ventures; risks associated with the Company's operations in
international markets; competition; dependence of the Company on third parties,
including suppliers; rapid technological change which could reduce the demand
for fiber optic systems; potential conflicts of interest with Ledcor Inc. and
its subsidiaries; the Company's negative cash flow during the network
construction period; the Company's substantial leverage; the Company's need for
additional borrowings; the ability of the Company to service its debt; the
Company's holding company structure; restrictions imposed by the terms of the
Company's indebtedness; the discretion of the Company's management over the use
of proceeds; extensive telecommunications regulation applicable to the Company;
the impact of currency exchange rate fluctuations; potential price volatility of
the Subordinate Voting Shares; the impact of future sales of the Subordinate
Voting Shares; the voting attributes of the Company's issued and outstanding
shares which may deter a third party from acquiring the Company; lack of
anticipated cash dividends; and dilution. See "Risk Factors" in the U.S.
Prospectus.

                        SUPPLEMENTAL CANADIAN DISCLOSURE

    In accordance with the requirements of applicable securities laws in all
provinces of Canada, the disclosure in the U.S. Prospectus incorporated in this
prospectus is supplemented with the following additional disclosure. ALL DOLLAR
AMOUNTS IN THIS PROSPECTUS ARE STATED IN U.S. DOLLARS EXCEPT WHERE OTHERWISE
INDICATED.

CORPORATE MATTERS

    The principal and head office of 360NETWORKS INC. (formerly Worldwide
Fiber Inc.) is located at 1500 - 1066 West Hastings Street, Vancouver, British
Columbia, Canada, V6E 3X1. The Company was incorporated under the laws of the
province of Alberta on February 5, 1998, was continued as a corporation under
the CANADA BUSINESS CORPORATIONS ACT on August 17, 1999 and intends to continue
as a corporation under the Companies Act (Nova Scotia) prior to the closing of
the offering. Immediately prior to the closing of the offering, the articles of
the Company will be amended so that the share capital has the rights and
attributes described in the U.S. Prospectus under "Share Capital Reorganization
and Description of Capital Stock".

FINANCIAL PRESENTATION

    Consistent with the Company's practice since its incorporation, its
historical consolidated financial statements and those of its predecessor
division are presented in accordance with United States generally accepted
accounting principles ("U.S. GAAP"). These financial statements are included in
the U.S. Prospectus. In accordance with applicable Canadian securities laws,
these financial statements have also been presented herein in accordance with
Canadian generally accepted accounting principles ("Canadian GAAP").

    The Company's historical consolidated financial statements under Canadian
GAAP (the "Canadian Statements") for the years ended December 31, 1999 and
December 31, 1998 and those of its predecessor division for the periods ended
May 31, 1998, August 31, 1997 and 1996 and March 31, 1996 differ materially from
the Company's historical consolidated financial statements under U.S. GAAP (the
"U.S. Statements") in the following three respects:

    - Under U.S. GAAP, all assets and liabilities were translated into United
      States dollars using period end exchange rates. Under Canadian GAAP,
      monetary assets and liabilities were translated into United States dollars
      using period end exchange rates and non-monetary assets and liabilities
      using historical exchange rates.

    - In the Company's consolidated financial statements for the year ended
      December 31, 1999, its redeemable convertible preferred shares are
      presented as a separate line item between liabilities and shareholders'
      equity in the U.S. Statements and are apportioned and presented as debt
      and equity components as required under Canadian GAAP in the Canadian
      Statements. As a result of this classification, additional interest
      expense of $25,977,000 on the redeemable convertible preferred shares has
      been recorded in the Canadian Statements.

    - As required under U.S. GAAP, stock-based compensation charges of
      $7.1 million have been recorded in the Company's U.S. Statements for the
      year ended December 31, 1999. In accordance with Canadian GAAP, no
      stock-based compensation charges have been recorded in the Canadian
      Statements.

CAPITALIZATION

    The table below describes the Company's consolidated cash and capitalization
presented in accordance with Canadian GAAP as of December 31, 1999 and as of
February 29, 2000 on an actual basis and on a pro forma as adjusted basis to
give effect to:

    - the issuance of 44,625,000 Subordinate Voting Shares for net proceeds to
      us of approximately $718 million;

    - the acquisition of all outstanding stock of GlobeNet;

    - the issuance of $1 billion of senior notes in the concurrent debt

PURCHASERS' STATUTORY RIGHTS

    Securities legislation in several of the provinces of Canada provides
purchasers with the right to withdraw from an agreement to purchase securities
within two business days after receipt, or deemed receipt, of a prospectus and
any amendment. In several of the provinces securities legislation also provides
a purchaser with remedies for rescission or, in some provinces, damages where
the prospectus and any amendment contains a misrepresentation or is not
delivered to the purchaser, provided that such remedies for rescission or
damages are exercised by the purchaser within the time limit prescribed by the
securities legislation of the purchaser's province. A purchaser should refer to
any applicable provisions of the securities legislation of the puchaser's
province for the particulars of these rights or consult with a legal advisor.

CONTINUOUS DISCLOSURE

    Upon the filing of the final prospectus with the securities regulatory
authorities in the various provinces of Canada, the Company will become a
reporting issuer under the securities laws of those of such jurisdictions that
provide for a reporting issuer regime. Pursuant to the rules of the securities
regulatory authorities of such jurisdictions, the Company is generally exempt
from certain of the requirements of the laws of such jurisdictions relating to
continuous disclosure. These rules generally permit the Company to comply with
certain informational requirements applicable in the U.S. instead of the
continuous disclosure requirements normally applicable in such Canadian
jurisdictions, provided that the relevant documents are filed with the
securities regulatory authorities in the relevant Canadian jurisdictions.

5 PRO FORMA CONSOLIDATED INCOME STATEMENT ASSUMPTIONS AND ADJUSTMENTS FOR THE
  YEAR ENDED DECEMBER 31, 1999

(I) ACQUISITION OF GLOBENET

    The pro forma income statement has been prepared to reflect the following
adjustments and assumptions resulting from the acquisition of GlobeNet:

    - The elimination of the amortization of deferred financing costs of
      $1,310,000 related to GlobeNet's debt.

    - The amortization of goodwill of $20,710,000.

    - The assumption that GlobeNet's long term debt will not be repaid as a
      result of a change in control of GlobeNet. If the Company had repurchased
      GlobeNet's $300,000,000 13% notes using proceeds from the Notes assumed to
      have an interest rate of 12%, pro forma interest expense net of taxes
      would be lower by $768,000 and a loss on extinguishment of debt net of
      taxes of $1,632,000 would have been recorded as a result of the premium
      paid on repurchase of GlobeNet's notes.

II)  MICHELS AND CN/IC MINORITY INTEREST ACQUISITIONS

    This adjustment records the amortization of goodwill from the acquisition of
the minority equity interests of Michels and CN/IC and elimination of minority
interest earnings assuming the acquisitions occurred on January 1, 1999.

III) INTEREST EXPENSE ON THE NOTES AND 1999 NOTES

    This adjustment records the interest expense, including amortization of
deferred financing costs of $158,971,000 for the year ended December 31, 1999,
assuming the Notes and the 1999 Notes were issued on January 1, 1999.
Amortization of the deferred financing costs was computed based on the effective
interest rate method. The Company would have a capitalized a portion of interest
expense related to the Notes and the 1999 Notes to the cost of the fiber optic
network assets constructed in 1999, which is not reflected in these pro forma
statements.

5 PRO FORMA CONSOLIDATED INCOME STATEMENT ASSUMPTIONS AND ADJUSTMENTS FOR THE
  YEAR ENDED DECEMBER 31, 1999 (CONTINUED)
IV) INCOME TAXES

    This adjustment records an income tax recovery of $29,455,000 for 1999 using
an effective tax rate of 45.6%. Management believes that, based on a number of
factors, it is more likely than not that the deferred tax asset will be fully
realized, such that no valuation allowance would be recorded.

V)  CAPITAL TAXES

    This adjustment records estimated additional B.C. Corporation Capital taxes
of $4,970,000 for 1999 and Federal Large Corporation taxes of $3,730,000 for
1999 resulting from the pro forma adjustments in notes 4 and 5.

VI) INTEREST ON DEBT COMPONENT OF REDEEMABLE CONVERTIBLE PREFERRED SHARES

    This adjustment eliminates interest on the debt component of the redeemable
convertible preferred shares assuming the shares were converted to Subordinate
Voting Shares on September 7, 1999 (date of issuance).

VII) PRO FORMA BASIC AND FULLY DILUTED LOSS PER SHARE

    The weighted average number of shares used to compute pro forma basic and
fully diluted loss per share is determined as follows:

                                AUDITORS' REPORT

To the Directors and Shareholders of 360NETWORKS INC.

We have audited the consolidated balance sheets of 360NETWORKS INC. (formerly
Worldwide Fiber Inc.) as at December 31, 1999 and 1998 and the consolidated
income statements, and statements of changes in shareholders' equity and cash
flows for the year ended December 31, 1999 and period from February 5, 1998
(date of incorporation) to December 31, 1998. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with Canadian generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance 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.

In our opinion, these consolidated financial statements present fairly, in all
material respects, the financial position of the Company as at December 31, 1999
and 1998 and the results of its operations and the changes in its cash flows for
the year ended December 31, 1999 and the period from February 5, 1998 (date of
incorporation) to December 31, 1998, in accordance with Canadian generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                           DECEMBER 31, 1999 AND 1998
            (TABULAR AMOUNTS EXPRESSED IN THOUSANDS OF U.S. DOLLARS)

1. THE COMPANY

    360NETWORKS INC. (formerly Worldwide Fiber Inc.) (the "Company") was
incorporated on February 5, 1998 and is indirectly a subsidiary of Ledcor Inc.
On May 31, 1998 the Company began its operations after certain assets of the
Telecommunications Division ("Division") of Ledcor Industries Limited
("Ledcor"), a Ledcor Inc. subsidiary were transferred to the Company. Prior to
June 1, 1998, the operations were carried out by the Division.

    The Company's operations consist of designing, engineering, constructing and
installing terrestrial and marine fiber optic systems for sale or lease to third
parties or for its own use. For the period ended December 31, 1998, the
Company's revenues related to Construction Services Agreements with Ledcor (see
Note 1(b)). For the year ended December 31, 1999, the Company's revenue is
primarily derived from the construction of fiber optic network assets for
telecommunications companies in North America.

    TRANSACTIONS WITH LEDCOR AND ITS AFFILIATES

 (a) On May 31, 1998, the Company entered into undertaking agreements whereby
     certain fiber optic network assets, located in Canada and the U.S. would be
     transferred to the Company by Ledcor in exchange for 319,995,200 Class A
     Non-Voting Shares. The Company constructed these assets for Ledcor under
     the Construction Services Agreements noted below. Construction of the
     assets was substantially complete at December 31, 1998 and the Company
     completed the exchange on March 31, 1999. This transaction was accounted
     for using the carrying values reported in the accounts of Ledcor as a
     transaction between a parent and a wholly owned subsidiary and accordingly,
     the fixed assets acquired by the Company will be recorded at the carrying
     amount of the assets in the accounts of Ledcor. The cost of the assets
     acquired at March 31, 1999 amounted to $21,883,000. As a result of the
     transaction, the Company also received a deferred tax benefit of $3,136,000
     which is reflected as a deferred tax asset.

    On May 28, 1999, the Company entered into an agreement with affiliates of
    Ledcor, whereby the Company would acquire certain fiber optic network
    assets. Closing occurred on September 27, 1999. As consideration, the
    Company issued 72,000,000 Class C Multiple Voting Shares to affiliates of
    Ledcor. In addition, the Company assumed certain rights and obligations
    under build agreements with a third party including obligations relating to
    the completion of those builds and certain support structure, maintenance,
    license and access, and underlying rights obligations. The cost of the fixed
    assets acquired amounted to $25,289,000, the cost of the assets in the
    accounts of Ledcor. The Company also received a deferred tax benefit of
    $3,341,000, as a result of a higher tax cost versus accounting cost of fixed
    assets. The Company also recorded deferred revenue of $25,000,000 relating
    to a build commitment assumed from Ledcor.

 (b) Construction Services Agreements were entered into May 31, 1998 to provide
     construction services to Ledcor to complete various projects including
     completion of the fiber optic network assets to be transferred to the
     Company. As the Company is required to obtain the fiber optic network
     assets from Ledcor, the revenues and costs associated with this portion of
     the agreement have not been reflected in the income statement for the
     period ended December 31, 1998. The costs to construct the network were
     reflected on completion of construction and the issuance of the shares. As
     at December 31, 1998, the Company had billed Ledcor $18,138,000 for the
     services related to

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                           DECEMBER 31, 1999 AND 1998
            (TABULAR AMOUNTS EXPRESSED IN THOUSANDS OF U.S. DOLLARS)

1. THE COMPANY (CONTINUED)
    construction of the fiber optic network assets which exceeded their costs by
     $2,099,000. This excess, net of income taxes of $945,000, had been excluded
     from the consolidated income statement and had been reported as contributed
     surplus included in other capital accounts.

 (c) A Management Services Agreement was entered into May 31, 1998 whereby
     Ledcor provides the Company with management staff, administrative and other
     support services. The Company reimburses Ledcor for direct costs and pays
     Cdn. $200,000 per month for the Company's share of corporate overheads.

 (d) Employee Services Agreements were entered into May 31, 1998 whereby the
     Company obtains the services of certain employees from Ledcor on a cost
     reimbursement basis.

 (e) The Company has entered into an agreement with Ledcor whereby personnel of
     Ledcor who were involved in the designing and planning of the transatlantic
     Hibernia cable stations will oversee management and supervision of
     construction of these facilities for a fee of approximately $1,700,000.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    BASIS OF PRESENTATION

    These consolidated financial statements have been prepared in accordance
with generally accepted accounting principles in Canada and include the accounts
of the Company, its wholly owned subsidiaries and its 75% interests in Worldwide
Fiber (USA), Inc. ("WFI USA"), WFI-CN Fiber Inc. and Worldwide Fiber IC LLC. All
significant intercompany transactions and balances have been eliminated on
consolidation. For investments where the Company exercises significant
influence, the investment is accounted for using the equity method.

    On December 31, 1998, the Company increased its interest in WFI USA from 50%
to 75% (note 5). The 1998 consolidated income statement and statement of cash
flows accounted for the Company's initial 50% interest in WFI USA using the
equity method for the period May 31, 1998 to December 31, 1998. The Company's
consolidated balance sheets include WFI USA's assets and liabilities, and
minority interest therein.

    USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions which affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and revenues and expenses for the period reported. Actual results
could differ from those estimates.

    CASH AND CASH EQUIVALENTS

    Cash and cash equivalents consists of cash on deposit and highly liquid
short-term interest bearing securities with maturity at the date of purchase of
three months or less.

            (TABULAR AMOUNTS EXPRESSED IN THOUSANDS OF U.S. DOLLARS)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    SHORT TERM INVESTMENTS

    Short term investments consist of highly liquid short term interest bearing
securities with maturities at the date of purchase greater than three months.
Interest earned is recognized immediately in the income statement.

    PROPERTY AND EQUIPMENT

    Fiber optic network assets constructed for the Company's own use are
recorded as property and equipment when the asset is fully constructed. Fiber
optic network assets, construction equipment and other assets are recorded at
cost. Property and equipment are depreciated using the following rates and
methods:

    - Fiber optic network assets--straight-line over 25 years.

    - Equipment--hourly usage rates, estimated to depreciate the equipment over
      the estimated useful lives of the equipment.

ASSETS UNDER CONSTRUCTION

    Assets under construction include fiber optic network assets constructed for
the company's own use and include direct expenditures of materials and labor,
indirect costs attributable to the projects and interest.

    LONG-LIVED ASSETS

    The Company reviews the carrying amount of long-lived assets for impairment
whenever events or changes in circumstances indicate that the carrying amount
may not be recoverable. The determination of any impairment would include a
comparison of estimated future operating cash flows anticipated to be generated
during the remaining life of the assets to the net carrying value of the asset.

    INVENTORY

    Inventory consists of fiber optic network assets to be sold or leased under
sales-type leases, construction supplies and small tools.

    Fiber optic network assets are recorded at the lower of cost and market.
Cost includes direct materials and subcontractor charges, labour, and interest
(see "capitalization of interest") determined on an average cost basis.

    Construction supplies and small tools inventory are recorded at the lower of
cost and replacement value.

    REVENUE RECOGNITION

    Revenue for services provided to Ledcor for construction projects is
recognized in the period the construction services are performed based on the
costs incurred.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                           DECEMBER 31, 1999 AND 1998
            (TABULAR AMOUNTS EXPRESSED IN THOUSANDS OF U.S. DOLLARS)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Revenue and income from construction contracts to develop fiber optic
network assets are determined on the percentage-of-completion basis using the
cost-to-cost method. Provision is made for all anticipated losses as soon as
they become evident. Claims for additional contract compensation are not
recognized until resolved.

    UNBILLED REVENUE

    Revenue recognized using the percentage-of-completion basis (see "Revenue
recognition") less billings to date is recorded as unbilled revenue. Unbilled
revenue classified as current represents billings expected to be collected
within the following fiscal year. Billings are rendered on the achievement of
certain construction milestones.

    CAPITALIZATION OF INTEREST

    Interest is capitalized as part of the cost of constructing fiber optic
network assets. Interest capitalized during the construction period is computed
by determining the average accumulated expenditures for each interim
capitalization period and applying the interest rate related to the specific
borrowings associated with each construction project. The total interest
capitalized as at December 31, 1999 was $17,467,000 (December 31, 1998--$nil).

    DEFERRED FINANCING COSTS

    Costs incurred in connection with obtaining the Senior Notes financing are
deferred and amortized, using the effective interest method, to interest expense
over the term of the senior notes.

    DEFERRED REVENUE

    Cash received from customers pursuant to contracts where construction has
not commenced is recorded as deferred revenue.

    FOREIGN CURRENCY TRANSLATIONS AND TRANSACTIONS

    The functional currency of the Company's operations located in countries
other than the U.S. is generally the domestic currency. The consolidated
financial statements are translated to U.S. dollars using the period-end
exchange rate for assets and liabilities and weighted-average exchange rates for
the period for revenues and expenses. Translation gains and losses are deferred
and accumulated as a component of other comprehensive income in shareholder's
equity. Net gains and losses resulting from foreign exchange transactions are
included in the consolidated income statement.

    INCOME TAXES

    Income taxes are accounted for using an asset and liability approach, which
requires the recognition of taxes payable or refundable for the current period
and deferred tax liabilities and assets for future tax consequences of events
that have been recognized in the Company's financial statements or tax returns.
The measurement of current and deferred tax liabilities and assets is based on
provisions of

                                     CF-11
<PAGE>
                                360NETWORKS INC.

            (TABULAR AMOUNTS EXPRESSED IN THOUSANDS OF U.S. DOLLARS)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
enacted tax laws; the effects of future changes in tax laws or rates are not
anticipated. The measurement of deferred tax assets is reduced, if necessary, by
a valuation allowance, where, based on available evidence, the probability of
realization of the deferred tax asset does not meet a more likely than not
criterion.

    FAIR VALUE OF FINANCIAL INSTRUMENTS

    The fair value of the Company's financial instruments, consisting of cash
and cash equivalents, short-term investments, accounts receivable, unbilled
revenue, due from parent, accounts payable and accrued liabilities, and income
taxes payable approximate their carrying values due to their short-term nature.
As at December 31, 1999, the fair value of the $500,000,000 12% Senior Notes was
$515,000,000 and the fair value of the $175,000,000 12.5% Senior Notes ("1998
Notes") was $182,000,000. The fair value of the 1998 Notes at December 31, 1998
approximated its carrying value. Fair value is based on a quoted market price.

    EARNINGS PER SHARE

    Basic earnings per share is computed by dividing net income available to
common stockholders by the weighted average number of common shares (including
Class A Non-Voting Shares, Class B Subordinate Voting Shares and Class C
Multiple Voting Shares) outstanding for the period. Fully diluted earnings per
share reflects the potential dilution of securities by including other potential
common stock, including stock options and Redeemable Convertible Preferred
Shares, in the weighted average number of common shares outstanding for a
period, if dilutive.

    The following table sets forth the computation of (loss) earnings per share:

5. ACQUISITIONS

    TELECOMMUNICATIONS DIVISION ASSETS

    Effective May 31, 1998, the Company entered into a series of agreements
whereby equipment, fiber optic network assets and other assets related to the
business of the Telecommunications Division of Ledcor were transferred to the
Company. In addition, the Company was granted a license to use Ledcor's patented
rail plow technology. This license agreement was for an initial term of ten
years, renewable annually upon completion of the initial term. As part of this
transaction, Ledcor retained all existing construction contracts related to the
business. This transaction was between entities under common control and has
been accounted for using the carrying amounts recorded in Ledcor's accounts. The
tax basis of substantially all the Canadian assets transferred to the Company
was Ledcor's carrying values whereas the tax basis of the U.S. assets
transferred was their fair value. The deferred tax balances were adjusted for
the change in the tax basis of the U.S. assets with the adjustment being
reflected as other capital accounts. As consideration for the transaction, the
Company issued 3,200 Class A shares to Ledcor.

    The assets transferred and consideration given, in connection with this
transaction were as follows:

    LEDCOM HOLDINGS LTD.

    On December 1, 1998 the Company acquired 50 Class A common shares
representing a 50% interest of Ledcom Holdings Ltd. ("Ledcom") from Worldwide
Fiber Holdings Ltd. ("WFHL"), the Company's parent. As consideration, the
Company issued 32,000,000 Class A Non-Voting Shares. Ledcom holds the patent to
Ledcor's rail plow technology, and in conjunction with this acquisition Ledcor
has committed to grant to the Company a worldwide exclusive license for the use
of the rail plow technology. The license will become non-exclusive six months
after a change of control of the Company. This transaction was between entities
under common control and has been accounted for using the carrying value of the
investment recorded in WFHL's accounts which was $nil.

    INVESTMENT IN WFI USA

    On August 31, 1998, the Company purchased Ledcor's 50% interest in, and a
promissory note of $3,915,000 from WFI USA, in exchange for 48,000,000 Class A
Non-Voting Shares of the Company and

5. ACQUISITIONS (CONTINUED)
the issuance of a promissory note by the Company. WFI USA was a joint venture
with Mi-Tech Communications LLC ("Mi-Tech") which held the remaining 50%
interest in WFI USA. WFI USA's operations consist primarily of developing fiber
optic network assets in the United States.

    As this transaction was between entities under common control, it was
accounted for in a manner similar to a pooling of interests. These financial
statements reflect the equity interest in the income of WFI USA from May 31,
1998 to December 31, 1998 in the amount of $928,000. Prior to May 31, 1998, the
equity interest was reported as part of the Telecommunications division of
Ledcor.

    On December 31, 1998 the Company increased its interest in WFI USA to 75% by
surrendering its note receivable from WFI USA of $3,915,000 for 100 non-voting
common shares and 100 Class A voting preferred shares of WFI USA. The
acquisition has been accounted for using the purchase method effective
December 31, 1998. The purchase price of the additional 25% has been allocated
to assets and liabilities based on their fair values. As a result, the net
assets acquired were as follows:

<TABLE>

</TABLE>

    On December 31, 1998, the Company entered into a Shareholders' Agreement
("Agreement") with Ledcor, Mi-Tech and Michels Pipeline Construction, Inc.
("Michels") (an affiliate of Mi-Tech). Pursuant to this agreement, Mi-Tech will
have the option to convert all of its 25% interest in WFI USA into shares of the
Company should the Company complete a public offering of shares with an
aggregate value of at least $20,000,000 or there is a change of control of WFI
USA. In connection with the conversion, Mi-Tech will be granted certain
registration rights in accordance with the Agreement. In addition, after the
tenth anniversary of this agreement, Mi-Tech has the option to require WFI USA
to purchase all of the shares owned by Mi-Tech and its affiliates at fair market
value. If Mi-Tech exercises this option, the Company can elect to sell all the
shares or assets of WFI USA in which case it will not be required to purchase
Mi-Tech's shares in WFI USA. In the event of a proposed sale of the shares of
WFI USA held by the Company, Mi-Tech will have certain tag-along rights.

    Also as part of the Agreement the Company:

    - Agreed not to participate in any projects or business nor provide advice
      or assistance to any business which undertakes projects within WFI USA's
      scope of business, as defined in the Agreement, for a period of four years
      from the date of the Agreement.

    - Is restricted from selling, transferring, encumbering or divesting its
      ownership or control of WFI USA.

    - WFI USA has an option to purchase from Mi-Tech 24 fiber optic strands
      along certain existing routes owned by Mi-Tech and its affiliates at fair
      market value.

6. DUE FROM PARENT

    The amounts due to and from parent are non-interest bearing, have no stated
terms of repayment and are due on demand. Contract amounts billed to parent and

assets to be transferred to the Company as described in note 1(b). The balance
as at December 31, 1999, of $7,297,000, is included in accounts payable.

12% payable semi-annually. The Notes are due August 1, 2009 and may be redeemed
by the Company on or after August 1, 2004 at certain specified redemption prices
ranging up to 106.00%. Up to 35% of the Notes may be redeemed by the Company
prior to August 1, 2002 at a redemption price of 112% of the principal amount
with the net proceeds from certain sales of the Company's common stock. If a
change in control occurs, as defined in the Notes indentures, the holders of the
Notes can require the company to repurchase all or part of the Notes at 101% of
the principal amount. Where excess proceeds from certain asset sales, as defined
in the Notes indentures, exceeds $10,000,000 the Company is required to make an
offer to repurchase the maximum amount of Notes that can be repurchased with
such excess proceeds at an offer price equal to 100% of the principal amount.

    On December 23, 1998, the Company issued $175,000,000 12.5% senior notes
(the "1998 Notes"). The 1998 Notes are unsecured obligations of the Company

Indenture, the holders of the 1998 Notes can require the Company to repurchase
all or part of the 1998 Notes at 101% of the principal amount. If at the end of
December 31, 2000 and semi-annually thereafter, the Company's Accumulated Excess
Cash Flow, as defined in the 1998 Notes Indenture, exceeds $10,000,000, the
Company is required to make an offer to repurchase the maximum principal amounts
of 1998 Notes that may be purchased by such Accumulated Excess Cash Flow Amount
at an offer price equal to 110% of the principal amount of the 1998 Notes. Under
this Excess Cash Flow provision, the Company is not required to repurchase more
than 25% of the original principal amount of the Notes prior to December 31,
2003.

    The Notes and 1998 Notes contain certain covenants that restrict the ability
of the Company and its subsidiaries to incur additional indebtedness, issue
certain preferred stock, pay dividends or make other distributions, repurchase
equity interests or subordinated indebtedness, engage in sale and leaseback
transactions, create certain liens, enter into certain transactions with
affiliates, sell assets of the Company or its subsidiaries, issue or sell equity

</TABLE>

    Management believes that, based on a number of factors, it is more likely
than not that the deferred tax asset will be fully utilized, such that no
valuation allowance has been recorded.

12. CONCENTRATION OF CREDIT RISK

    Financial instruments that potentially subject the Company to a significant
concentration of credit risk consist primarily of cash and cash equivalents,
short-term investments, accounts receivable, unbilled revenue and due from
parent which are not collateralized. The Company limits its exposure to credit
loss by placing its cash and cash equivalents and short-term investments with
high credit quality financial institutions. Concentrations of credit risk with
respect to accounts receivable and unbilled revenue are considered to be limited
due to the credit quality of the customers comprising the Company's customer
base. The maximum amount of credit risk exposure is limited to the carrying
amounts of these financial instruments.

    The Company performs ongoing credit evaluations of its customers' financial
condition to determine the need for an allowance for doubtful accounts. The
Company has not experienced significant credit losses to date. Accounts
receivable was comprised of 22 customers at December 31, 1999 and 12 customers
at December 31, 1998.

    The concentration of credit risk relating to the amount due from the parent
is considered limited due to the credit quality of the Company's parent. As
described in Note 1, substantially all of the Company's revenues for the period
ended December 31, 1998 was earned from construction services provided to
Ledcor.

Company formed subsidiary companies with CN (WFI-CN Fibre Inc.) and IC
(Worldwide Fiber LLC) (the Company having a 75% interest and CN or IC having the
remaining 25% interest) for the purpose of licensing the rights-of-way from CN
and IC and developing the projects along the Routes.

15. UNCERTAINTY DUE TO THE YEAR 2000 ISSUE

    The Year 2000 Issue arises because many computerized systems use two digits
rather than four to identify a year. Date-sensitive systems may recognize the
year 2000 as 1900 or some other date, resulting in errors when information using
the year 2000 dates is processed. In addition, similar problems may arise in
some systems which use certain dates in 1999 to represent something other than a
date. Although the change in date has occurred, it is not possible to conclude
that all aspects of the year 2000 Issue that may affect the entity, including
those related to customers, suppliers or other third parties, have been fully
resolved.

To the Directors of
Ledcor Industries Limited

    We have audited the divisional balance sheets of Ledcor Industries
Limited--Telecommunications Division as at May 31, 1998, August 31, 1997 and
August 31, 1996 and the divisional statements of operations and retained
earnings and cash flows for the nine months ended May 31, 1998, year ended
August 31, 1997, five months ended August 31, 1996 and year ended March 31,
1996. These financial statements are the responsibility of the Division's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

    We conducted our audits in accordance with Canadian generally accepted
auditing standards. Those standards require that we plan and perform an audit to
obtain reasonable assurance 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.

    In our opinion, these divisional financial statements present fairly, in all
material respects, the financial position of the Division as at May 31, 1998,
August 31, 1997 and August 31, 1996 and the results of its operations and cash
flows for the periods ended May 31, 1998, August 31, 1997, August 31, 1996 and

                  NOTES TO THE DIVISIONAL FINANCIAL STATEMENTS

                       (ALL FIGURES ARE IN U.S. DOLLARS)

1. DESCRIPTION OF BUSINESS

    The Telecommunications Division (the "Division") is a division of Ledcor
Industries Limited ("LIL") which, in turn, is a wholly-owned subsidiary of
Ledcor Inc. The Division is in the business of providing long-haul fiber optic
systems, including planning, design, construction and maintenance to
telecommunications clients. The Division headquarters are in Vancouver, Canada
and its principal geographic areas of operation for these fiber optic systems
are Canada and the United States.

    The accompanying divisional financial statements include the assets,
liabilities, revenues and expenses of the Division. Since the Division has been
operating as a fully integrated part of the Company, all construction equipment
owned by LIL, but used in the Division's operations, was identified by LIL's
management and allocated to the Division. In addition, certain assets,
liabilities, revenues and expenses have been recorded by the Division using
management's best estimates (Note 3).

    The divisional financial statements have been prepared from the divisional
records maintained by LIL and may not necessarily be indicative of the
conditions that would have existed or the results of operations if the Division
had been operated as a stand-alone company.

    The Division does not hold any cash or cash equivalents. LIL uses central
bank accounts to deposit receipts and make payments on behalf of the Division.
These transactions are reflected in the inter-divisional account (Note 8).

    On May 31, 1998, LIL transferred the net assets (at book value) and the
operations of the Division to Worldwide Fiber Inc. (indirectly a wholly-owned
subsidiary of Ledcor Inc.).

2. ACCOUNTING POLICIES

    A)  BASIS OF ACCOUNTING

       These divisional financial statements have been prepared in accordance
       with Canadian generally accepted accounting principles.

    B)  ACCOUNTING FOR CONTRACTS

       Revenue and income from construction contracts to develop fiber optic
       systems are determined on the percentage of completion basis using the
       cost-to-cost method. Due to the risks inherent in these contracts,
       management makes a provision for risk using their best estimate. This
       method is used because management considers costs incurred to be the best
       available measure of progress on these contracts. Provision is made for
       all anticipated losses as soon as they become evident. Claims for
       additional contract compensation are not recognized until resolved.

    C)  UNBILLED REVENUE

       Unbilled revenue comprises costs incurred and margin in excess of
       billings and advance deposits, representing unperformed work, on
       uncompleted contracts.

                                     CF-32

                       (ALL FIGURES ARE IN U.S. DOLLARS)

2. ACCOUNTING POLICIES (CONTINUED)
    D)  INVENTORY

       Inventory consists of fiber optic strands under construction and is
       valued at the lower of cost or market. Cost is determined using the full
       absorption method whereby the fiber optic strands have been allocated
       their proportionate share of materials, labour and overhead incurred.

    E)  FIXED ASSETS

       Construction equipment, fiber optic strands and other assets are recorded
       at cost. Fixed assets are depreciated using the following rates and
       methods:

       - Construction equipment--hourly usage rates, estimated to depreciate the
         equipment, over estimated useful lives, ranging from three to five
         years.

       - Fiber optic strands, under construction--depreciation, at appropriate
         rates, will be provided for when the related fiber optic systems are in
         use.

       - Other assets-straight--line method over the estimated useful lives of
         the assets, ranging from three to five years.

    F)  INCOME TAXES

       These are the financial statements of a Division, and not of a taxable
       legal entity. However, these financial statements present income taxes as
       if the Division was a stand-alone taxable legal entity. Current and
       deferred income taxes have been determined by applying the asset and
       liability method.

       The asset and liability method of accounting for income taxes recognizes
       deferred tax assets and liabilities for the future tax consequences
       attributable to temporary differences between the financial statement
       carrying amounts of existing assets and liabilities and their respective
       tax bases. Deferred tax assets and liabilities are measured using enacted
       tax rates expected to apply to taxable income in the years in which those
       temporary differences are expected to be recovered or settled.

    G)  TRANSLATION OF FOREIGN CURRENCY

       The functional currency of the Division is the Canadian dollar. The
       financial statements are translated into United States dollars.
       Transactions are translated into United States dollars at rates of
       exchange at the time of such transactions. At balance sheet date,
       monetary assets and liabilities are translated at current rates of
       exchange. Exchange gains and losses are included in the divisional
       statement of operations. There were no long-term foreign currency
       denominated monetary items during these periods.

3. USE OF ESTIMATES IN THE FINANCIAL STATEMENTS

    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 at the
dates of the divisional financial statements and the reported amounts of
revenues and expenses during the reporting periods. Actual results could differ
from those estimates.

                                     CF-33

            NOTES TO THE DIVISIONAL FINANCIAL STATEMENTS (CONTINUED)

                       (ALL FIGURES ARE IN U.S. DOLLARS)

3. USE OF ESTIMATES IN THE FINANCIAL STATEMENTS (CONTINUED)
    Unbilled revenue, inventory, fiber optic strands capitalized, and revenue
have all been calculated using management's best estimates. Total estimated
costs is a component of the percentage of completion calculation which
determines revenue recognized, unbilled revenue, inventory and fiber optic
strands capitalized. However, there may be unforeseen conditions which could
include weather patterns, the continuing deterioration of the Canadian dollar,
and the outcome of ongoing negotiations. Such conditions could substantially
change the values of the above mentioned items reflected in these financial
statements. The impact of these unforeseen conditions cannot be estimated by
management as at May 31, 1998.

    Corporate expenses are allocated from LIL to the Division based on a
percentage of the Division's revenue. Management is of the opinion that this
allocation percentage is reasonable since all divisions fully absorb LIL's
corporate expenses. Management regularly reviews this allocation basis and
considers the amounts allocated to fairly represent actual corporate expenses
incurred, on behalf of the Division, for the periods reported on. Because the
Division is fully integrated, management is unable to estimate the actual
corporate expenses that would have been incurred if the Division had operated on
a stand-alone basis.

    Interest is allocated from LIL by charging a floating rate of prime plus 1%
on the net cash position of the Division's projects at the end of each month.
Management has capitalized interest by capitalizing the portion of interest
costs incurred to date which relates to inventory and capital assets.

    The Division has no additional debt accruing interest which should be
capitalized. In addition, LIL has no additional debt which would result in
significant interest being allocated and capitalized.

4. TRADE ACCOUNTS RECEIVABLE AND ACCOUNTS RECEIVABLE HOLDBACKS

    Trade accounts receivable are presented net of the allowance for doubtful
accounts (which was nil for all years reported on since the Division has not
experienced any bad debts).

    Accounts receivable holdbacks represent amounts billed but not yet paid
under retainage provisions in the project contracts. These provisions state that
holdbacks will be collected upon substantial completion of the projects.

    The Division's provision for deferred taxes approximates the amounts
computed by applying the Canadian and United States statutory rates to income
before taxes. There are no permanent differences or other reconciling items that
would result in an effective tax rate which is different from the statutory
rates applied.

    A)  FIBER OPTIC CONSTRUCTION PROJECT

       In 1996, the Division commenced construction of a Canadian-U.S. fiber
       optic telecommunications system (the Canadian FOTS) that is scheduled for
       completion in early 1999.

    B)  FONOROLA CONTRACT

       In a variety of contracts, commencing in April, 1997, the Division sold
       fiber optic strands of the Canadian FOTS. The Division has a commitment
       to complete construction of the fiber optic strands.

    C)  BELL CANADA CONTRACT

       In February, 1998, the Division sold fiber optic strands of the Canadian
       FOTS. The Division has a commitment to complete construction of the fiber
       optic strands.

    D)  METRONET CONTRACT

       Subsequent to period end (September, 1998), the Division sold fiber optic
       strands of the Canadian FOTS. The Division has a commitment to complete
       construction of the fiber optic strands.

    E)  LEASE COMMITMENTS

       The Division is committed under non-cancellable leases for equipment for
       the period ending April, 1999 in the amount of $826,271. The Division has
       an option to withdraw from all leases in April, 1999 and therefore has no
       commitments beyond that date. Lease expenses were the following:

    The Division also had significant accounts receivable from FONOROLAwhich
accounted for the following percentages of trade accounts receivable:

FONOROLA.................       39%              52%                94%
</TABLE>

    The Division is receiving cash from this customer on a consistent basis and
management expects to collect on all other accounts receivables. Therefore no
provision for bad debts has been recorded for the reported periods. Based on
this significant customer's creditworthiness, the Division has not required it
to provide collateral against these receivables.

    There were no significant accounts payable to significant suppliers at the
balance sheet dates. However, since significant purchases are made from Pirelli
Cables, should this supplier fail to honor its contract and the Division was not
able to find a substitute supplier, the Division would not be able to meet its
commitments to complete the construction of the Canadian FOTS, as noted in 9(a).

11. FINANCIAL INSTRUMENTS

    Financial instruments consist of recorded accounts receivables (and other
like accounts) which will result in future cash receipts, as well as accounts
payables, (and other like accounts) that will result in future cash outlays.

    The carrying values of the financial instruments of the Division as at
May 31, 1998, August 31, 1997 and August 31, 1996 were approximately equal to
their estimated fair market values at these dates, due to the short-term nature
of these instruments. Subjective judgment and uncertainties arise in the
determination of estimated fair market values. Accordingly, the aggregate fair
value should not be interpreted as being realizable in an immediate settlement
of the instruments.

13. UNCERTAINTY DUE TO THE YEAR 2000 ISSUE

    The Year 2000 Issue arises because many computerized systems use two digits
rather than four to identify a year. Date-sensitive systems may recognize the
year 2000 as 1900 or some other date, resulting in errors when information using
year 2000 dates is processed. In addition, similar problems may arise in some
systems which use certain dates in 1999 to represent something other than a
date. The effects of the Year 2000 Issue may be experienced before, on, or
after, January 1, 2000 and, if not addressed, the impact on operations and
financial reporting may range from minor errors to significant systems failure
which could affect the Division's ability to conduct normal business operations.
It is not possible to be certain that all aspects of the Year 2000 Issue
affecting the Division, including those related to the efforts of customers,
suppliers, or other third parties, will be fully resolved.

14. SUBSEQUENT EVENTS

    A) AGREEMENTS WITH WFI

       Effective May 31 1998, LIL entered into a series of agreements to sell
       the equipment, fiber optic strands and certain other assets related to
       the business of Worldwide Fiber Inc. (an indirect wholly-owned subsidiary
       of Ledcor Inc.) ("WFI"). In addition, WFI was granted a licence by LIL to
       use certain processes related to the business. This licence agreement is
       for an initial term of ten years and will be renewable annually upon
       completion of the initial term. As part of this transaction, LIL retained
       all existing construction contracts related to the business. This
       transaction was between entities under common control and has been
       accounted for using the carrying amounts recorded in LIL's accounts. As
       consideration for the transaction, LIL was issued 200 Class A shares by
       WFI.

14. SUBSEQUENT EVENTS (CONTINUED)
    B) DISPOSITION OF FIBER ASSETS

       As part of these agreements WFI undertook to purchase from LIL certain
       fiber optic system assets, located in both Canada and the U.S., which
       were not completed at May 31, 1998. These assets will be purchased by WFI
       upon their completion, which is estimated to be late 1998 or early 1999.
       As consideration, WFI will issue a total of 19,999,700 Class A common
       shares to LIL. These transactions are between entities under common
       control and, will be accounted for at their original construction costs.

    C) CONSTRUCTION SERVICES

       WFI has agreed to provide construction services to LIL to complete
       certain construction contracts for fiber optic strands and related
       facilities to third party customers.

TO THE DIRECTORS AND SHAREHOLDERS OF
GLOBENET COMMUNICATIONS GROUP LIMITED

We have audited the accompanying consolidated balance sheets of GLOBENET
COMMUNICATIONS GROUP LIMITED as at December 31, 1999 and 1998 and the
consolidated statements of shareholders' equity, operations and cash flows for
the years ended December 31, 1999, 1998 and 1997. 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 Canadian generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance 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.

In our opinion, these consolidated financial statements present fairly, in all
material respects, the financial position of GLOBENET COMMUNICATIONS GROUP
LIMITED as at December 31, 1999 and 1998 and the results of its operations and
its cash flows for the years ended December 31, 1999, 1998 and 1997 in

1 NATURE OF OPERATIONS

    GlobeNet Communications Group Limited provides international
telecommunications services to both residential and commercial customers and is
a provider of telecommunications capacity. The Company is currently developing a
fibre optic submarine cable system called Atlantica-1 that will link Bermuda,
North and South America and offer capacity between major cities in the United
States, Bermuda, Brazil, Venezuela and Argentina. Atlantica-1 is currently being
constructed.

    In November 1997, the Company deployed a fibre optic submarine cable system
which connects Bermuda and the United States ("BUS-1"). The Company provides
international telecommunications services to both residential and commercial
customers in Bermuda through a subsidiary company, TeleBermuda International
Limited ("TBI") through the BUS-1.

    On January 10, 1997, TBI was granted its public telecommunications service
licence in Bermuda under the provisions of the Telecommunications Act, 1986 and
the Public Telecommunication Service (Licence) Regulations, 1988 for a five-year
term and began commercial operations in May 1997. TBI has an interconnection
agreement with the Bermuda Telephone Company ("BTC"), the domestic carrier in
Bermuda. No consideration was paid by the Company in relation to these
agreements.

2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    These consolidated financial statements are prepared in accordance with
Canadian generally accepted accounting principles ("Canadian GAAP"). These
principles conform in all material respects with accounting principles generally
accepted in the United States ("United States GAAP") except as described in
note 19. The following is a summary of the significant accounting policies
followed in the preparation of these consolidated financial statements.

    PRINCIPLES OF CONSOLIDATION

    The consolidated financial statements include the accounts of the Company
and all of its subsidiary companies. Intercompany accounts and transactions have
been eliminated on consolidation.

    USE OF SIGNIFICANT ACCOUNTING ESTIMATES

    The preparation of financial statements in conformity with Canadian
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could significantly differ from those
estimates.

    REVENUE, DEFERRED REVENUE AND COST RECOGNITION

    REVENUE:  The Company provides telecommunication services and the granting
or leasing of indefeasible rights of use ("IRU") interests in its
telecommunications infrastructure.

    The Company records as revenue the amount of telecommunications services
rendered, as measured primarily by the minutes of traffic processed, after
deducting an estimate of the traffic for which revenue will not be collected.
Historical deductions have not been material. Service discounts and

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

              FOR THE YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997
       (IN THOUSANDS OF U.S. DOLLARS, EXCEPT SHARE AND PER SHARE AMOUNTS)

2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
incentives are accounted for as a reduction of revenue when granted, or where
provided in relation to a service contract, rateably over the contract period.

    The Company has entered into certain IRU agreements. Such agreements are
accounted for as either service or lease transactions. Those IRU agreements that
meet all of the following characteristics have been accounted for as leases:

(a) The purchaser has exclusive right to the purchased capacity for a specified
    period, generally the estimated useful life of the system, which is
    25 years.

(b) The Company cannot sell or otherwise use any of the purchaser's unused
    capacity for the term of the agreement.

(c) The purchased capacity is physically limited to discrete channels on the
    purchaser's own dedicated circuits at a specified amount of capacity, which
    cannot be exceeded. The specific circuits are agreed to by the parties.

(d) The Company has no right to move the purchased capacity to another discrete
    channel from the purchaser's dedicated circuits without the purchaser's
    permission.

    IRU agreements that meet these criteria are accounted for as lease
transactions. If the transactions meet the sales type lease criteria, including
those related to collectibility of the payments and the absence of any important
uncertainties surrounding unreimbursable costs yet to be incurred by the
Company, then revenue is recognized in the period that the IRUs are transferred
and the capacity is available for service. If these criteria are not met, the
transactions are accounted for as operating leases and revenue is recognized
over the term of the lease.

    To date, the Company has not entered into any IRU agreements that are
considered to be service transactions. Revenue from service transactions would
be recognized as earned over the term of the agreement.

    In addition, we note that the accounting for sales of capacity is evolving,
and is currently under consideration by accounting standard setters. Any change
in accounting literature may affect the timing and method of recognition of
these revenues and related costs.

    Revenues from private line services are recognized as earned.

    DEFERRED REVENUE:  Rent from the operating leases of capacity in the
telecommunications infrastructure to third party carriers is deferred and
recognized over the term of the lease on a straight-line basis. Revenue from the
sale of prepaid calling cards is recognized as the services are provided.

    COST:  Carrier charges are comprised primarily of local access charges and
international termination costs. These costs are recognized based on traffic
volume.

    FIXED ASSETS

    Fixed assets are recorded at cost less accumulated amortization.
Amortization commences when an asset is available for use, and is calculated in
a systematic manner based on the expected useful lives of the assets as follows:

    CONSTRUCTION IN PROGRESS

    Construction in progress includes direct expenditures for the construction
of the Company's Atlantica-1 project and is stated at cost. Costs are
capitalized once it is probable that the fibre optic cable system will be
constructed, otherwise they are expensed as incurred. Capitalized costs include
costs incurred under the construction contract, advisory, consulting and legal
fees and interest.

    DEFERRED FINANCING COSTS

    Deferred financing costs represent debt issuance costs, which are amortized
over the estimated term of the related debt.

    INVESTMENTS

    The Company's investments are accounted for using the equity method.

    FOREIGN CURRENCY TRANSLATION

    Monetary assets and liabilities denominated in foreign currencies are
translated into U.S. dollars at exchange rates prevailing at the balance sheet
date. Revenues and expenses are translated into U.S. dollars at the average
rates of exchange prevailing at the dates of the respective transactions.
Transactions are translated into U.S. dollars at the exchange rates in effect at
the time the transactions occur. Exchange gains and losses arising on
translation are included in the operating results for the year.

    Assets and liabilities of non-Bermudian subsidiaries where the functional
currency is other than the U.S. dollar are translated at the exchange rate in
effect at the balance sheet date. Revenues and expenses are translated at
average exchange rates prevailing during the year.

2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    FINANCIAL INSTRUMENTS

    The fair value of financial assets and liabilities represents the amount at
which these instruments could be exchanged in an arm's length transaction
between willing parties.

    As at December 31, 1999, the carrying amounts of financial assets and
liabilities in the consolidated balance sheet approximate their fair values due
to the short-term nature of these instruments.

    The reported amount of fixed rate long-term debt instruments is estimated to
approximate fair value as actual rates are consistent with rates estimated to be
currently available for debt of similar terms and remaining maturities.

    In addition, the Company has entered into an interest rate cap agreement to
modify the interest characteristics of part of its outstanding long-term debt.
This agreement involves an exchange of amounts based on a fixed interest rate
for amounts based on a variable interest rate whenever the interest rate exceeds
the cap specified in the agreement. The premium paid by the Company upon
entering in the agreement is amortized over the term of the agreement and
recognized as an adjustment of interest expense related to the debt. The Company
does not use derivative financial instruments for speculative trading purposes.
As of December 31, 1999, the carrying value approximates fair value.

    INCOME TAXES

    Under current Bermuda laws, the Company is not required to pay any taxes in
Bermuda on either income or capital gains. The Company has received an
undertaking from the Minister of Finance in Bermuda, pursuant to the Exempted
Undertakings Tax Protection Act 1966, which exempts the Company from any such
tax until March 28, 2016. Subsidiaries in other jurisdictions are subject to
local taxes.

    STOCK BASED COMPENSATION

    The Company does not recognize compensation cost at the time options are
granted unless the exercise price is less than the market price of the stock on
the measurement date.

10 GRANTING OF INDEFEASIBLE RIGHTS OF USE AND LEASING OF THE FIBRE OPTIC
SUBMARINE CABLE

    a)  During 1998, the Company granted indefeasible rights of use ("IRUs") in
       its fibre optic submarine cable to certain third party carriers for a
       period of 25 years for $1,521. The costs recognized with the granting of
       the IRUs are calculated as total capacity granted in relation to the
       total cost of the activated fibre optic submarine cable times the total
       cost of the fibre optic submarine cable system. In addition, under these
       IRU agreements, the third party carrier is responsible for paying its pro
       rata share of restoration costs. These costs are accounted for as
       expenses as they are incurred, less a recovery of expense being recorded
       to reflect the required pro rata reimbursement from the IRU customer.

    b)  The Company has entered into an agreement to provide capacity in its
       fibre optic submarine cable to a third party. This arrangement is being
       accounted for as an operating lease. The term of the lease is for the
       greater of 25 years or the operational life of the fibre optic submarine
       cable. If the operational life is less than 10 years, the Company must
       provide a refund on a pro rata basis for each year short of the 10-year
       period. For the first four years of the agreement, the Company is
       responsible for maintenance and operating costs, thereafter the lessee
       will pay a monthly charge for operating and maintenance costs. The total
       rental payment for this agreement was $8,000, of which $4,000 was paid in
       1999 and $3,000 in 1998. The remaining payment of $1,000 is due on
       September 24, 2000. Lease income is being recognized on a straight-line
       basis over the 25-year term. During 1999, lease income of $315
       (1998--$263; 1997--$nil) was recognized.

       Under this agreement, the third party has the right to enter into a
       second lease of capacity in the fibre optic submarine cable commencing
       September 24, 2001. The consideration for the second lease will be $4,000
       payable upon activation of the second circuit. If the third party elects
       not to proceed with the second lease a penalty of $250 is payable to the
       Company.

11 MINORITY INTEREST AND EQUITY ACCOUNTED FOR INVESTMENTS

    ROCOM TBI LIMITED

    During 1998, the Company sold its interest in Rocom TBI Limited, a

    i)  On December 18, 1998 and May 21, 1999, the Board of Directors issued
       263,000 options and 5,000 options, respectively to employees and certain
       officers and directors at an exercise price of $9.00 per option, vesting
       over a three-year period, under the 1998 Share Option and Incentive Plan.
       In July 1999, when these options were approved by the shareholders, the
       market price of these options was $20.40. The difference between the
       market price and the exercise price has been reflected as deferred
       compensation in the statement of shareholders' equity and is being
       amortized over the vesting period as at December 31, 1999. Compensation
       expense in the amount of $1,794 has been recorded in the financial
       statements.

       On July 9, 1999, 35,000 options, with an exercise price of $19.00 with a
       ten-year term were granted to certain directors. The market price of
       these options on the measurement date was $20.40. The vesting of these
       options occurred on July 14, 1999. The difference between the exercise
       price and market price at the time of vesting amounted to $49 and has
       been reflected as compensation expense.

       On April 12, 1999, the Company granted 540,000 options at an exercise
       price of $9.00 with a ten-year term to certain officers and directors.
       These options vest in three separate tranches based upon the Company
       meeting certain milestones related to the Atlantica-1 project. On
       July 14, 1999, the first vesting milestone occurred on 165,000 of these
       options, when the financing was secured and the vesting period for
       another 165,000 options was determined. The difference between the
       exercise price and the market value amortized over the vesting period
       amounted to $2,364 and has been reflected as compensation expense.

       On October 7, 1999, the Company granted 429,019 options at an exercise
       price of $20.40 to certain officers. Of these options, 129,019 vest
       immediately and 300,000 vest over three years although vesting on these
       options may be accelerated as a result of certain events.

              FOR THE YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997
       (IN THOUSANDS OF U.S. DOLLARS, EXCEPT SHARE AND PER SHARE AMOUNTS)

13 COMMON SHARE OPTIONS (CONTINUED)
       On October 22, 1999, the Company granted 5,000 options at an exercise
       price of $19.00 to an employee. These options vest over three years.

    Total stock-based compensation expense included in general and
administrative expenses for the year ended December 31, 1999 is $4,207
(1998--$nil; 1997--$nil).

14 BASIC AND FULLY DILUTED LOSS PER COMMON SHARE

    The basic loss per common share is calculated using the weighted average
number of common shares outstanding of 9,911,341 (1998 - 3,515,927;
1997 - 3,492,915). The weighted average number of common shares on a fully
diluted basis is calculated on the same basis as the basic weighted average
number of shares as the Company is in a loss position and the effects of
possible conversion would be anti-dilutive.

15 SUPPLEMENTAL INFORMATION

    i)  Included in general and administrative expense are the following:

    b)  On June 16, 1999, the Company entered into a supply contract with
       Alcatel Submarine Networks ("Alcatel") to construct a fibre optic
       submarine cable called Atlantica-1 for a total contract price of
       $620,861, (of which $93,129 has been recorded at December 31, 1999),
       which is subject to amendment by the mutual agreement of the parties.

       Future payments are based upon a specified billing schedule and are due
       when the corresponding project milestone has been achieved and engineer
       acceptance has been provided. The future minimum payments, beyond the
       $93,129 that has been recorded as of December 31, 1999, required as a
       result of the contract, are as follows:

       construction costs under its participation in a cable network
       construction and maintenance agreement.

    d)  In the normal course of business, the Company has also entered into a
       number of contracts under which it is committed to the purchase and
       supply of telecommunication services at fixed prices. It is not
       anticipated that losses will be incurred on these contracts.

18 UNCERTAINTY DUE TO THE YEAR 2000 ISSUE

    The Year 2000 Issue arises because many computerized systems use two digits
rather than four to identify a year. Date-sensitive systems may recognize the
year 2000 as 1900 or some other date, resulting in errors when information using
year 2000 dates is processed. In addition, similar problems may arise in some
systems which use certain dates in 1999 to represent something other than a
date. Although the change in date has occurred, it is not possible to conclude
that all aspects of the Year 2000 Issue that may affect the entity, including
those related to customers, suppliers, or other third parties, have been fully
resolved.

19 RECONCILIATION TO UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES

    The consolidated financial statements of the Company have been prepared in
accordance with Canadian GAAP. The following adjustments and/or additional
disclosures, would be required in order to present the financial statements in
accordance with United States GAAP.

    a)  Stock based compensation

       The Company applies APB Opinion 25 ("Accounting for Stock Issued to
       Employees") in accounting for its stock option plan, and, accordingly
       does not recognize compensation cost at the time options are granted
       unless the exercise price is less than the market price of the stock on
       the measurement date.

       Had the Company elected to recognize compensation cost based on the fair
       value of the options granted at the grant date as prescribed by
       SFAS 123, the pro forma effects to reported net loss for the year and
       basic and fully diluted loss per common share, would be as follows:

<TABLE>
<CAPTION>
                                                         1999       1998       1997
                                                          $          $          $
                                                       --------   --------   --------
<S>                                                    <C>        <C>        <C>
Net loss for the year--as reported...................   15,906     4,944      5,296
Net loss for the year--pro forma.....................   15,906     5,047      5,296
Basic and fully diluted loss per common share--as
  reported...........................................     1.60      1.41       1.52
Basic and fully diluted loss per common share--pro
  forma..............................................     1.60      1.43       1.52
</TABLE>

       The fair value of each option grant has been estimated using the
       Black-Scholes option pricing model, using a volatility assumption of 20%
       (1998 - 20%; 1997 - 20%), expected life of 7 years (1998 - 7 years;
       1997 - 7 years), a dividend rate of nil (1998--$nil; 1997--$nil) and a
       risk-free interest rate of 5.64% (1998 - 5.28%; 1997 - 6.33%).

       The above pro forma effects on the net loss for the year may not be
       representative of the effects on the net loss for the year for future
       periods as option grants typically vest over several years and additional
       options are generally granted each year.

19 RECONCILIATION TO UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES
(CONTINUED)
    b)  Revenue recognition

       FASB Interpretation No. 43, "Real Estate Sales--an interpretation of FASB
       Statement No. 66," was issued in June 1999. It clarifies the standards
       for recognition of profit on all real estate sales transactions,
       including those related to fibre optic cable that cannot be removed and
       used separately from the real estate without incurring significant costs.
       This interpretation is effective for all applicable transactions after
       June 30, 1999. However, no such transactions have been entered into after
       June 30, 1999 and we have not yet completed our analysis of the
       applicability or the impact of this statement on future transactions.

    c)  Derivative instruments and hedging activities

       In June 1998, the Financial Accounting Standards Board issued SFAS
       No. 133 ("SFAS 133"), "Accounting for Derivative Instruments and Hedging
       Activities" which is effective for fiscal years beginning after June 15,
       2000. SFAS 133, as amended, requires the Company to recognize all
       derivatives as either assets or liabilities and measure those instruments
       at fair value. It further provides criteria for derivative instruments to
       be designated as fair value, cash flow, and foreign currency hedges and
       establishes respective accounting standards for reporting changes in the
       fair value of the derivative instruments. Upon adoption, the Company will
       be required to adjust hedging instruments to fair value in the balance
       sheet and recognize the offsetting gains or losses as adjustments to be
       reported in net income or other comprehensive income, as appropriate.
       Management has not determined the impact of this statement on its
       financial position, results of operations and cash flows.

20 SUBSEQUENT EVENT

    On February 15, 2000, the Company signed a contract variation with Alcatel
for the fixed price turnkey supply of all six undersea cable stations and the
associated overland routes from the cable stations to the cable beach landing
points at a cost of approximately $50 million.

ITEM 17. UNDERTAKINGS.

    The undersigned registrant hereby undertakes:

    (1) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities 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 its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue;


    (2) That, for purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of Prospectus filed as part of
this Registration Statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective; and


    (3) That, for the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

                                VOTING AGREEMENT


     THIS VOTING AGREEMENT (the "AGREEMENT") is entered into as of March 11,
2000, between the undersigned shareholders (the "SHAREHOLDERS") of GlobeNet
Communications Group Limited, a Bermuda company (the "COMPANY"), and Worldwide
Fiber Inc., a Canadian corporation ("WFI").

     WHEREAS, concurrently with the execution and delivery of this Agreement,
WFI and the Company have entered into an Agreement and Plan of Arrangement dated
as of March 10, 2000 (the "ARRANGEMENT AGREEMENT"), providing for the exchange
of shares of the Company and WFI (the "ARRANGEMENT") pursuant to the terms and
conditions of the Arrangement Agreement, and setting forth certain
representations, warranties, covenants and agreements of the parties thereto in
connection with the Arrangement; and

     WHEREAS, as an inducement and a condition to WFI entering into the
Arrangement Agreement, pursuant to which each Shareholder will receive Class A
Voting Shares, of WFI as specified in the Arrangement Agreement (the "WFI Class
A Stock") in exchange for each common share, par value $1.50 per share, of the
Company ("COMMON SHARES") and each share of Class B restricted voting shares,
par value $1.50 per share, of the Company ("CLASS B SHARES" and with the Common
Shares, collectively, "COMPANY COMMON STOCK") owned by such Shareholder, the
Shareholders each have agreed to enter into this Agreement;

     NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

     1. REPRESENTATIONS OF SHAREHOLDERS. Each of the Shareholders severally
represents as to himself or herself that such Shareholder:

          (a) is the holder in the capacity set forth on Exhibit A hereto of
     that number of shares of Company Common Stock set forth opposite such
     Shareholder's name on Exhibit A (such Shareholder's "SHARES");

          (b) does not beneficially own (as such term is defined in the
     Securities Exchange Act of 1934, as amended (the "1934 ACT")) any shares of
     Company Common Stock other than his or her Shares;

          (c) has the right, power and authority to execute and deliver this
     Agreement and to perform his obligations under this Agreement, and this
     Agreement has been duly executed and delivered by such Shareholder and
     constitutes a valid and legally binding agreement of such Shareholder,
     enforceable in accordance with its terms, subject to bankruptcy,
     insolvency, fraudulent transfer, reorganization, moratorium and similar
     laws of general applicability relating to or affecting creditors' rights
     and to general equity



<PAGE>

     principles; and such execution, delivery and performance by Shareholder of
     this Agreement will not (i) conflict with, require a consent, waiver or
     approval under, or result in a breach of or default under, any of the terms
     of any contract, commitment or other obligation (written or oral) to which
     such Shareholder is a party or by which such Shareholder is bound; (ii)
     violate any order, writ, injunction decree or statute, or any rule or
     regulation, applicable to Shareholder or any of the properties or assets of
     Shareholder; or (iii) result in the creation of, or impose any obligation
     on such Shareholder to create, any lien, charge or other encumbrance of any
     nature whatsoever upon the Shares;

          (d) There is no private or governmental action, suit, proceeding,
     claim, arbitration or investigation pending before any agency, court or
     tribunal, foreign or domestic, or, to the knowledge of such Shareholder or
     any of his affiliates, threatened against such Shareholder or any of his
     affiliates or any of their respective properties or any of their respective
     officers or directors, in the case of a corporate entity (in their
     capacities as such) that, individually or in the aggregate, could
     reasonably be expected to have a material adverse effect on his ability to
     consummate the transactions contemplated by this Agreement and the
     Arrangement Agreement. There is no judgment, decree or order against such
     Shareholder or any of his affiliates or, to the knowledge of such
     Shareholder or any of his affiliates, any of their respective directors or
     officers, in the case of a corporate entity (in their capacities as such)
     that could prevent, enjoin, alter or materially delay any of the
     transactions contemplated by this Agreement and the Arrangement Agreement,
     or that could reasonably be expected to have a material adverse effect on
     such Shareholder's ability to consummate the transactions contemplated by
     this Agreement and the Arrangement Agreement.

          (e) the Shares are now and will at all times during the term of this
     Agreement be held by such Shareholder, or by a nominee or custodian for the
     account of such Shareholder, free and clear of all pledges, liens, proxies,
     claims, charges, security interests, preemptive rights and any other
     encumbrances whatsoever with respect to the ownership, transfer or voting
     of such Shares; and except for the Amended and Restated Securityholders'
     Agreement, dated July 14, 1999 among the Company and 22 shareholders of the
     Company, there are no outstanding options, warrants or rights to purchase
     or acquire, or other agreements relating to, such Shares other than this
     Agreement.

The representations and warranties contained herein shall be made as of the date
hereof and on the date that the Arrangement is consummated.

     2. AGREEMENT TO VOTE SHARES. Each of the Shareholders severally agrees to
vote his or her Shares and any New Shares (as defined in Section 7 hereof), and
shall cause any holder of record of his or her Shares or New Shares to vote, (a)
in favor of adoption and approval of the Arrangement Agreement and the
Arrangement (and each other action and transaction contemplated by the
Arrangement Agreement and this Agreement) at every meeting of the shareholders
of the Company at which such matters are considered and at every adjournment
thereof and (b) against any action or proposal



                                       2
<PAGE>

that would compete with or could serve to materially interfere with, delay,
discourage, adversely affect or inhibit the timely consummation of the
Arrangement. Any such vote shall be cast or consent shall be given in accordance
with such procedures relating thereto as shall ensure that it is duly counted
for purposes of determining that a quorum is present and for purposes of
recording the results of such vote or consent. Each Shareholder severally agrees
to deliver to WFI upon request a proxy substantially in the form attached hereto
as Exhibit B, which proxy shall be coupled with an interest and irrevocable to
the extent permitted under Bermuda law, with the total number of such
Shareholder's Shares and any New Shares correctly indicated thereon. Each
Shareholder also agrees to use his reasonable efforts to take, or cause to be
taken, all action, and do, or cause to be done, all things necessary or
advisable in order to consummate and make effective the transactions
contemplated by this Agreement.

     3. NO VOTING TRUSTS. After the date hereof, the Shareholders severally
agree that they will not, nor will they permit any entity under their control
to, deposit any of their Shares in a voting trust or subject any of their Shares
to any arrangement with respect to the voting of such Shares other than
agreements entered into with WFI.

     4. NO PROXY SOLICITATIONS. Each of the Shareholders severally agrees that
such Shareholder will not, nor will such Shareholder permit any entity under
their control to, (a) solicit proxies or become a "participant" in a
"solicitation" (as such terms are defined in Regulation 14A under the 1934 Act)
in opposition to or competition with the consummation of the Arrangement or
otherwise encourage or assist any party in taking or planning any action which
would compete with or otherwise could serve to materially interfere with, delay,
discourage, adversely affect or inhibit the timely consummation of the
Arrangement in accordance with the terms of the Arrangement Agreement, (b)
directly or indirectly encourage, initiate or cooperate in a shareholders' vote
or action by consent of the Company's shareholders in opposition to or in
competition with the consummation of the Arrangement, or (c) become a member of
a "group" (as such term is used in Section 13(d) of the 1934 Act) with respect
to any voting securities of the Company for the purpose of opposing or competing
with the consummation of the Arrangement; provided, that the foregoing shall not
restrict any director of the Company from taking any action such director
believes is necessary to satisfy such director's fiduciary duty to shareholders
of the Company.

     5. TRANSFER AND ENCUMBRANCE. On or after the date hereof, each of the
Shareholders severally agrees not to voluntarily transfer, sell, offer, pledge
or otherwise dispose of or encumber ("TRANSFER") any of his or her Shares or New
Shares prior to the earlier of (a) the effective date of the Arrangement or (b)
the date this Agreement shall be terminated in accordance with its terms, except
that each of the Shareholders will be permitted to Transfer any of his or her
Shares or New Shares to an Affiliate (as defined in the Arrangement Agreement)
of such Shareholder provided, that such Affiliate agrees in writing to be bound
by the terms of this Agreement with respect to such Shares and New Shares.

     6. LEGEND. As soon as practicable after the execution of this Agreement,
each Shareholder shall surrender to the Company the certificates representing
the Shares



                                       3
<PAGE>

in his or her possession (and within 30 days the Shares not in his or her
possession), shall cause the following legend to be placed on the certificates
representing such Shares (in addition to any existing legend) and shall request
that such legend remain thereon until the earlier of (i) expiration or
termination of this Agreement or (ii) the consummation of the Arrangement:

          "The shares of capital stock represented by this certificate are
          subject to a Voting Agreement, dated as of March 10, 2000, among the
          Shareholders named therein and WFI, which, among other things, (a)
          restricts the sale or transfer of such shares except in accordance
          therewith, and (b) restricts the voting of such shares except in
          accordance therewith."

In the event that WFI requests that a proxy be executed and delivered by a
Shareholder to it pursuant to Section 2 hereof, such Shareholder shall promptly
surrender to the Company the certificates representing the Shares covered by
such proxy and cause the foregoing legend to be revised to add to the end of
such legend the following words:

          ", and such shares are also subject to an irrevocable proxy."

Each Shareholder shall provide WFI with reasonably satisfactory evidence of its
compliance with this Section 6 on or prior to the date five business days after
the execution hereof with respect to Shares in his possession (or within 30 days
with respect to Shares not in his possession) or of the request relating to such
Shareholder's proxy, as the case may be.

     7. ADDITIONAL PURCHASES. Each of the Shareholders severally agrees that in
the event (i) any stock dividend, stock split, recapitalization,
reclassification, combination or exchange of shares of capital stock of the
Company on, of or affecting the Shares of a Shareholder, (ii) such Shareholder
purchases or otherwise acquires beneficial ownership of any shares of Company
Common Stock after the execution of this Agreement, or (iii) such Shareholder
voluntarily acquires the right to vote or share in the voting of any shares of
Company Common Stock other than the Shares (collectively, "NEW SHARES"), such
Shareholder agrees to deliver promptly to WFI upon request of WFI an irrevocable
proxy substantially in the form attached hereto as Exhibit B with respect to
such New Shares. Each of the Shareholders also severally agrees that any New
Shares acquired or purchased by him or her shall be subject to the terms of this
Agreement to the same extent as if they constituted Shares.

     8. WFI CLASS A STOCK. Each of the Shareholders severally agree, that for a
period of 12 months commencing on the date of the Initial Public Offering (as
defined in the Arrangement Agreement), not to voluntarily Transfer any of the
WFI Class A Stock which it receives pursuant to the Arrangement Agreement,
except that each of the Shareholders will be permitted to Transfer any of the
WFI Class A Stock which it receives pursuant to the Merger Agreement to an
Affiliate of such Shareholder or a limited partner of such Shareholder,
provided, that such Transfer is exempt from registration under the Securities
Act of 1933, as amended and provided, further, that such



                                       4
<PAGE>

Affiliate or limited partner agrees in writing to be bound by the terms of this
Agreement with respect to such shares of WFI Class A Stock.

     9. SPECIFIC PERFORMANCE. Each party hereto severally acknowledges that it
will be impossible to measure in money the damage to the other parties if a
party hereto fails to comply with any of the obligations imposed by this
Agreement, and that, in the event of any such failure, the other parties will
not have an adequate remedy at law or damages. Accordingly, each party hereto
severally agrees that injunctive relief or other equitable remedy, in addition
to remedies at law or damages, is the appropriate remedy for any such failure.
Each party hereto severally agrees that it will not seek, and agrees to waive
any requirement for, the securing or posting of a bond in connection with any
other party's seeking or obtaining such equitable relief.

     10. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and assigns
and shall not be assignable without the written consent of all other parties
hereto.

     11. ENTIRE AGREEMENT. This Agreement supersedes all prior agreements,
written or oral, among the parties hereto with respect to the subject matter
hereof and contains the entire agreement among the parties with respect to the
subject matter hereof. This Agreement may not be amended, supplemented or
modified, and no provisions hereof may be modified or waived, except by an
instrument in writing signed by all the parties hereto. No waiver of any
provisions hereof by any party shall be deemed a waiver of any other provisions
hereof by any such party, nor shall any such waiver be deemed a continuing
waiver of any provision hereof by such party.

     12. MISCELLANEOUS.

          (a) This Agreement shall be deemed a contract made under, and for all
     purposes shall be construed in accordance with, the laws of the State of
     New York without regard to principles of conflict of laws.

          (b) If any provision of this Agreement or the application of such
     provision to any person or circumstances shall be held invalid by a court
     of competent jurisdiction, the remainder of the provision held invalid and
     the application of such provision to persons or circumstances, other than
     the party as to which it is held invalid, shall not be affected.

          (c) This Agreement may be executed in one or more counterparts, each
     of which shall be deemed to be an original but all of which together shall
     constitute one and the same instrument.

          (d) This Agreement shall terminate upon the earliest to occur of (i)
     the Effective Time (as defined in the Arrangement Agreement) or (ii)
     termination of the Arrangement Agreement.

                                  FORM OF PROXY


     The undersigned, for consideration received, hereby appoints ? or ? and
each of them my proxies, with power of substitution, to vote all (i) common

Bermuda company (the "Company") and (ii) Class B restricted voting shares, par
value $1.50 per share, of the Company, owned by the undersigned at the Special
Meeting of Shareholders of the Company to be held [insert date, time and place]
and at any adjournment thereof FOR approval and adoption of the Agreement and
Plan of Arrangement, dated as of March 10, 2000, by and among the Company and
Worldwide Fiber Inc., a Canadian corporation ("WFI"), providing for the exchange
of shares (the "Arrangement") of the Company and WFI, and the Arrangement, and
AGAINST any action or proposal that would compete with or could serve to
materially interfere with, delay, discourage, adversely affect or inhibit the

                                 TRUST AGREEMENT

         THIS AGREEMENT made as of the ____ day of ____________, 2000.

AMONG:

                  WORLDWIDE FIBER HOLDINGS LTD., of --

                  GREGORY B. MAFFEI, of --

                  MADISON SQUARE INC., of --

                  LARRY R. OLSEN, of --

                  (herein called the "Shareholders")

                                      -and-

                  WORLDWIDE FIBER INC., of 1500 - 1066 West Hastings Street,
                    Vancouver,  British Columbia, V6E 3X1

                  (herein called the "Company")

                                     -and -

                  -- TRUST COMPANY, of --

                  (herein called the "Trustee")

     WHEREAS there are -- Class C Multiple Voting Shares of the Company (the
"Multiple Voting Shares") issued and outstanding, all of which are owned by the
Shareholders;

     AND WHEREAS the Shareholders and the Company are desirous of entering into
this Agreement to secure the listing of the Class A Non-Voting Shares of the
Company (the "Non-Voting Shares") on The Toronto Stock Exchange and to derive
the benefits of such listing, and for the purpose of ensuring that the holders
from time to time of the Non-Voting Shares will not be deprived of any rights
under applicable take-over bid legislation to which they would have been
entitled in the event of a take-over bid if the Multiple Voting Shares and the
Non-Voting Shares were of a single class of shares, the Shareholders have agreed
that an aggregate of -- Multiple Voting Shares (the "Subject Multiple Voting
shares") as set out in Schedule A attached hereto, representing 80% of the
issued and outstanding Multiple Voting shares, will be subject to the terms of
this Agreement;

     AND WHEREAS the Shareholders and the Company desire to constitute the
Trustee as a trustee for the holders from time to time of the Non-Voting Shares
to the intent that


<PAGE>
                                      -2-


such holders, through the Trustee, will receive the benefits of the covenants of
the Shareholders and the Company contained in this Agreement;

     NOW THEREFORE THIS AGREEMENT WITNESSETH that in consideration of the
premises and agreements herein contained and for other good and valuable
consideration, the receipt of which is hereby acknowledged, the parties hereto
agree as follows:

1.   Subject to Section 2, the Shareholders shall not sell any Subject Multiple
Voting Shares, directly or indirectly, pursuant to a take-over bid, as defined
by applicable securities legislation, under circumstances in which securities
legislation would have required the same offer or a follow-up offer to be made
to holders of Non-Voting Shares if the sale had been of Non-Voting Shares rather
than Multiple Voting Shares, but otherwise on the same terms. For this purpose,
it shall be assumed that the offer that would have resulted in such sale of
Non-Voting Shares would have constituted a take-over bid under applicable
securities legislation, regardless of whether this actually would have been the
cause.


2.   Section 1 shall not apply to prevent a sale of Subject Multiple Voting
Shares by a Shareholder pursuant to a take-over bid if:

     (a)  such sale is made pursuant to an offer to purchase Multiple Voting
          Shares made to all holders of Multiple Voting Shares, and an identical
          offer (in terms of price per share, percentage of outstanding shares
          to be taken up exclusive of shares owned immediately prior to the
          offer by the offeror, or associates or affiliates of the offeror, and
          in all other material respects) concurrently is made to purchase
          Non-Voting Shares, which identical offer has no condition attached
          other than the right not to take up and pay for shares tendered if no
          shares are purchased pursuant to the offer for Multiple Voting Shares;
          or

     (b)  there is a concurrent unconditional offer to purchase all of the
          Non-Voting Shares at a price per share at least as high as the highest
          price per share paid pursuant to the take-over bid for the Multiple
          Voting Shares, and for the purposes of this Section 2 the varying of
          any term of an offer shall be deemed to constitute the making of a new
          offer.

3.   If the conditions attaching to the shares of the Company include a
provision that would have the effect of changing the voting rights attaching to
shares of the Company under certain circumstances, through an automatic
conversion of shares of one class into shares of another class or otherwise, and
if there is an offer that would have been a take-over bid if not for the
existence of such provision, such offer shall be deemed to be a "take-over bid"
for the purposes of this Agreement.

4.   For greater certainty, any sale which would result in a direct or indirect
acquisition of Subject Multiple Voting Shares or Non-Voting Shares, or in a
direct or indirect acquisition of control or direction over such shares, be
construed to be a sale of such Subject Multiple Voting Shares or Non-Voting
Shares, as the case may be, for the purposes of Section 1.


<PAGE>
                                      -3-


5.   Each Shareholder shall use its best efforts to prevent any person or
company it controls from carrying out a sale (including an indirect sale)
described in Section 1 in respect of any Subject Multiple Voting Shares owned
from time to time by such Shareholder, regardless of whether such person or
company is a party to this Agreement, unless Subsection 2(a) or 2(b) applies in
respect of such sale.

6.   If a Shareholder, or any person or company it controls, carries out a sale
(including an indirect sale) described in Section 1 in respect of any Subject
Multiple Voting Shares owned from time to time by such Shareholder, and if
neither Subsection 2(a) or 2(b) applies in respect of such sale, the Shareholder
shall not at the time such sale becomes effective or thereafter do any of the
following with respect to any of the Subject Multiple Voting Shares so sold: (a)
dispose of them without the prior written consent of the Trustee; (b) convert
them into Non-Voting Shares without the prior written consent of the Trustee; or
(c) exercise any voting rights attaching to them except in accordance with the
written instructions of the Trustee, and the Shareholder shall comply with such
instructions. The Trustee may attach conditions to any consent the Trustee gives
in exercising its rights hereunder. The Trustee shall exercise such rights in a
manner that the Trustee considers to be: (i) in the best interests of the
holders of the Non-Voting Shares, other than the Shareholders and other holders
thereof who, in the opinion of the Trustee, participated directly or indirectly
in the transaction that triggered the operation of this Section 6; and (ii)
consistent with the intentions of the Shareholders and the Company in entering
into this Agreement as such intentions are set out in the preamble to this
Agreement.

7.   No Shareholder shall dispose of any Subject Multiple Voting Shares,
directly or indirectly, unless the disposition is conditional upon the person or
company acquiring the shares entering into an agreement in the form of this
Agreement and under which such person or company shall have the same rights and
obligations as the Shareholder hereunder. If the conditions attaching to the
shares of the Company include a right of conversion of Multiple Voting Shares
into Non-Voting Shares, neither the exercise of such right nor the subsequent
sale of the Non-Voting shares resulting from the conversion shall constitute a
disposition of Subject Multiple Voting Shares for the purposes of this Section
7.

8.   If and whenever the Trustee has reasonable cause to believe that a
Shareholder or the Company may have breached, or may intend to breach, any
provision of this Agreement, the Trustee shall make reasonable enquiry to
determine whether such a breach has occurred or is intended, and if the Trustee
thereupon determines that such is the case the Trustee shall forthwith deliver
to the Company a certificate stating that the Trustee has made such
determination. The Trustee shall thereupon be entitled to take and, subject to
Section 10, shall take such action as the Trustee considers necessary to enforce
its rights under this Agreement on behalf of the holders of the Non-Voting
Shares.

9.   Subject to Section 10, if and whenever holders of not less than 10% of the
then outstanding Non-Voting Shares determine that a Shareholder or the Company
has breached, or intends to breach, any provision of this Agreement, such
holders may require the Trustee to take action in connection therewith by
delivering to the Trustee a requisition in writing signed in one or more
counterparts by such holders and setting forth the action to be taken by the
Trustee, and upon receipt by the Trustee of such a requisition the Trustee shall
forthwith take such action as is

<PAGE>
                                      -4-


specified in the requisition and any other action that the Trustee considers
necessary to enforce its rights under this Agreement on behalf of the holders of
the Non-Voting Shares.

10.  The obligation of the Trustee to take any action on behalf of the holders
of the Non-Voting Shares shall be conditional upon the Trustee receiving from
the Company or from one or more holders of Non-Voting Shares such funds and
indemnity as the Trustee may reasonably require in respect of any costs or
expenses which it my incur in connection with any such action. The Company shall
provide such funds and indemnity to the Trustee if the Trustee has delivered to
the Company the certificate referred to in Section 8.

11.  No holder of Non-Voting Shares shall have the right, other than through the
Trustee, to institute any action or proceeding or to exercise any other remedy
for the purpose of enforcing any rights arising from this Agreement unless
holders of Non-Voting Shares shall have requested in the manner specified in
Section 9 that the Trustee act and shall have provided reasonable funds and
indemnity to the Trustee and the Trustee shall have failed to so act within 30
days after the provision of such funds and indemnity. In such case any holder of
Non-Voting Shares acting on behalf of such holder and all other holders of
Non-Voting Shares shall be entitled to take proceedings in any court of
competent jurisdiction such as the Trustee might have taken.


12.  The Company shall do all things reasonably necessary to facilitate the due
performance of this Agreement, including the fulfilment by the Shareholders of
their obligations hereunder.

13.  The Trustee may resign and be discharged from all further duties and
liabilities hereunder, subject to this Section 13, after giving three months'
written notice to the Company, or such shorter notice as the Company may accept
as sufficient. In the event that the office of trustee becomes vacant, the
Company shall forthwith appoint a new trustee which shall be a corporation
authorized to carry on the business of a trust company in British Columbia;
failing such appointment, the Shareholders, the Trustee or any holder of
Non-Voting Shares may apply to a judge of the Supreme Court of British Columbia
for the appointment of a new trustee. Upon any new appointment the new trustee
shall be vested with the same powers, rights, duties and responsibilities as if
it had been originally named herein as the trustee, but there shall be
immediately executed, at the expense of the Company, all such instruments as may
be, in the opinion of counsel to the Company, necessary or desirable to assure
such vesting. Any resignation of the Trustee shall not become effective until
the successor party shall have executed an appropriate instrument accepting the
appointment as the new trustee.

14.  The Shareholders and the Company agree to indemnify and save harmless the
Trustee from and against all claims made against it by reason of the Trustee's
compliance in good faith with the terms hereof.

15.  The Company shall pay the reasonable fees and expenses of the Trustee in
connection with the performance of the Trustee's obligations hereunder,
including the reasonable fees and disbursements of counsel, but this Section 15
shall not require the Company to pay any fees or expenses in connection with any
action taken by the Trustee pursuant to Section 9


<PAGE>
                                      -5-


if the Trustee has not delivered to the Company the certificate referred to in
Section 8 in respect of such action.

16.  The Trustee hereby accepts the appointment as trustee for the holders from
time to time of the Non-Voting Shares upon the terms and conditions herein set
forth.

17.  This Agreement shall not be amended, and no provision thereof shall be
waived, except with the approval of at least two-thirds of the votes cast by the
holders of Non-Voting Shares present or represented at a meeting duly called for
the purpose of considering such amendment or waiver.

18.  Notwithstanding Section 17, the Company and the Trustee may, without
     reference to the holders of the Non-Voting Shares, amend this Agreement if
     such amendment is, in the opinion of the Trustee:

     (a)  beneficial to the holders of the Non-Voting Shares;

     (b)  for the purpose of complying with the legislation, rules or policies
          of any applicable regulatory authority; or

     (c)  necessary or desirable to overcome administrative difficulties arising
          in connection with administration of this Agreement;

and such amendment does not, in the opinion of the Trustee, adversely affect the
holders of the Non-Voting Shares.

19. Any notice or other communication required or contemplated under this
Agreement shall be sufficiently given if it is in writing and delivered,
telecopied or sent by prepaid registered mail to the following:

     if to the Shareholders:

                            Exchange of Certificates

         4.1. EFFECT ON CAPITAL STOCK. At the Effective Time, as a result of the
Arrangement and without any action on the part of the holder of any shares of
the Company:


         (a) ARRANGEMENT CONSIDERATION. (i) Each common share, par value $1.50
per share, of the Company (a "COMMON SHARE") issued and outstanding immediately
prior to the Effective Time (other than Common Shares owned by Parent or any
direct or indirect subsidiary of Parent (collectively, the "PARENT COMPANIES")
or Common Shares that are owned by any direct or indirect subsidiary of the
Company and in each case not held on behalf of third parties (each, an "EXCLUDED
SHARE" and collectively, "EXCLUDED SHARES")) shall be exchanged for that number
of Class A Subordinate Voting Shares of Parent ("PARENT CLASS A STOCK") equal to
(i) (x) 323,141,801 (300 million PLUS the Aggregate Strike Price (as defined
below)) DIVIDED BY 18,952,099 (the number of Common Shares outstanding, on a
fully diluted basis, as of the date of this Agreement) DIVIDED BY (y)) the
lesser of (A) 10 billion DIVIDED BY that number of shares of New Parent Capital
Stock (other than the Parent Class B Subordinate Voting Shares) to be
outstanding immediately following the Initial Public Offering (as defined below)
and (B) the Initial Public Offering Price PLUS (ii) (x) 323,141,801 (300 million
PLUS the Aggregate Strike Price DIVIDED BY 18,952,099 (the number of Common
Shares outstanding, on a fully diluted basis, as of the date of this Agreement))
DIVIDED BY (y) the Initial Public Offering Price (as defined below), stated as a
number ((i) and (ii) together the "ARRANGEMENT CONSIDERATION"). The "INITIAL
PUBLIC OFFERING PRICE" shall be the price of the first closed sale under a firm
commitment underwritten public offering of Parent Class A Stock pursuant to a
registration statement on Form F-1 (the "Initial Public Offering") under the
Securities Act of 1933, as amended (the "SECURITIES ACT"). The "AGGREGATE STRIKE
PRICE" shall be the aggregate exercise price for all Company Options (as defined
herein) outstanding as of the date of this Agreement. At the Effective Time, all
Common Shares (other than Excluded Shares) shall be transferred to, and
registered in the name of, Parent and a certificate for all such Common Shares
shall be issued and registered in the name of Parent, and each certificate (a
"CERTIFICATE") formerly representing any of such Common Shares shall thereafter
represent the right of the holders such Common Shares to receive the Parent
Class A Stock to which they are entitled pursuant to this Section 4.1.



                                       3
<PAGE>


         (ii) In consideration for the Parent Class A Stock issued pursuant to
Section 4.1(a)(i) (and for no further consideration) each class B restricted
voting share, par value $1.50 per share, of the Company (a "CLASS B SHARE" and
together 9with the Common Shares, the "SHARES") issued and outstanding
immediately prior to the Effective Time shall be transferred to, and registered
in the name of, Parent.

         (b) EXCLUDED SHARES. Each Excluded Share shall, by virtue of the
Arrangement and without any action on the part of the holder thereof, be
transferred to, and registered in the name of, Parent for no consideration.

         (c) FRACTIONAL SHARES. Notwithstanding any other provision of this
Agreement, no fractional shares of Parent Class A Stock will be issued. Parent
shall round to the nearest whole share, with .50 being rounded downward, the
number of shares of Parent Class A Stock that any holder of Shares would be
entitled to receive as Arrangement Consideration but for this Section 4.1(c).

         4.2. EXCHANGE OF CERTIFICATES FOR SHARES. (a) EXCHANGE AGENT. As of the
Effective Time, Parent shall deposit, or shall cause to be deposited, with an
exchange agent selected by Parent with the Company's prior approval, which shall
not be unreasonably withheld (the "EXCHANGE AGENT"), for the benefit of the
holders of Shares (other than holders of Excluded Shares), certificates
representing the shares of Parent Class A Stock to be issued pursuant to the
last sentence of Section 4.1(a) in exchange for Shares outstanding immediately
prior to the Effective Time upon due surrender of the Certificates (or
affidavits of loss or indemnities in lieu thereof) pursuant to the provisions of
this Article IV (such certificates for shares of Parent Class A Stock being
hereinafter referred to as the "EXCHANGE FUND").

         (b) EXCHANGE PROCEDURES. Promptly after the Effective Time, Parent
shall cause the Exchange Agent to mail to each holder of record of Shares (other
than holders of Excluded Shares) (i) a letter of transmittal specifying that
delivery shall be effected, and risk of loss to the Certificates shall be
issued, only upon delivery of the Certificates (or affidavits of loss or
indemnities in lieu thereof) to the Exchange Agent, such letter of transmittal
to be in such form and have such other provisions as Parent and the Company may
reasonably agree, and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for certificates representing shares of Parent
Class A Stock. Subject to Section 4.2(g), upon surrender of a Certificate to the
Exchange Agent together with such letter of transmittal, duly executed, the
holder of such Certificate shall be entitled to receive in exchange therefor a
certificate representing that number of whole shares of Parent Class A Stock
that such holder is entitled to receive pursuant to this Article IV.
Certificates surrendered to the Exchange Agent shall be held by the Exchange
Agent for delivery to Parent in a manner to be agreed upon by Parent and the
Exchange Agent. In the event of a transfer of ownership of Shares that is not
registered in the transfer records of the Company, a certificate representing
the proper number of shares of Parent Class A Stock may be issued to such a
transferee if the Certificate formerly representing such Shares is presented to
the Exchange Agent, accompanied by all documents required to

evidence and effect such transfer. If any certificate for shares of Parent Class
A Stock is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it shall be a condition of such
exchange that the Person (as defined below) requesting such exchange shall
provide evidence satisfactory to Parent with respect thereto.

         For the purposes of this Agreement, the term "PERSON" shall mean any
individual, corporation (including not-for-profit), general or limited
partnership, limited liability company, joint venture, estate, trust,
association, organization, Governmental Entity (as defined in Section 5.1(d)) or
other entity of any kind or nature.

         (c) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES; VOTING. (i) All
shares of Parent Class A Stock to be issued pursuant to the Arrangement shall be
deemed issued and outstanding as of the Effective Time and whenever a dividend
or other distribution is declared by Parent in respect of the Parent Class A
Stock, the record date for which is at or after the Effective Time, that
declaration shall include dividends or other distributions in respect of all
shares issuable pursuant to this Agreement. No dividends or other distributions
in respect of the Parent Class A Stock shall be paid to any holder of any
unsurrendered Certificate until such Certificate is surrendered for exchange in
accordance with this Article IV. Subject to the effect of applicable laws,
following surrender of any such Certificate, there shall be issued to the holder
of the certificates representing whole shares of Parent Class A Stock issued in
exchange therefor, without interest, (A) at the time of such surrender, the
dividends or other distributions with a record date after the Effective Time
theretofore payable with respect to such whole shares of Parent Class A Stock
and not paid and (B) at the appropriate payment date, the dividends or other
distributions payable with respect to such whole shares of Parent Class A Stock
with a record date after the Effective Time but with a payment date subsequent
to surrender.

         (ii) Holders of unsurrendered Certificates shall be entitled to vote
after the Effective Time at any meeting of Parent shareholders the number of
whole shares of Parent Class A Stock represented by such Certificates,
regardless of whether such holders have exchanged their Certificates.

         (d) TRANSFERS. After the Effective Time, there shall be no transfers on
the stock transfer books of the Company of the Shares that were outstanding
immediately prior to the Effective Time other than to Parent.

         (e) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund that
remains unclaimed by the shareholders of the Company for 180 days after the
Effective Time shall be returned to Parent. Any shareholders of the Company who
have not theretofore complied with this Article IV shall thereafter look only to
Parent for issuance of the Certificates for their shares of Parent Class A Stock
upon due surrender of their Certificates (or affidavits of loss or indemnity in
lieu thereof), without any interest thereon. Notwithstanding the foregoing, none
of Parent, the Exchange Agent or any other



                                       5
<PAGE>


Person shall be liable to any former holder of Shares for any amount properly
delivered to a public official pursuant to applicable abandoned property,
escheat or similar laws.

         (f) LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any
Certificate shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the Person claiming such Certificate to be lost,
stolen or destroyed or the posting by such Person of a bond in customary amount
as indemnity against any claim that may be made against it with respect to such
Certificate, as determined by Parent, the Exchange Agent will issue and deliver
in exchange for such lost, stolen or destroyed Certificate the shares of Parent
Class A Stock and any unpaid dividends or other distributions in respect thereof
pursuant to Section 4.2(c).

         (g) AFFILIATES. Notwithstanding anything herein to the contrary,
Certificates surrendered for exchange by any Affiliate (as determined pursuant
to Section 6.8) of the Company shall not be exchanged until Parent has received
a written agreement from such Person as provided in Section 6.8 hereof.

         4.3. ADJUSTMENTS TO PREVENT DILUTION. In the event that the Company
changes the number of Shares or securities convertible or exchangeable into or
exercisable for Shares, or Parent changes the number of shares of Parent Class A
Stock or securities convertible or exchangeable into or exercisable for shares
of Parent Class A Stock, issued and outstanding prior to the Effective Time as a
result of a reclassification, stock split (including a reverse split), stock
dividend or distribution, recapitalization, Arrangement, subdivision, issuer
tender or exchange offer, or other similar transaction, the Arrangement
Consideration shall be equitably adjusted, PROVIDED, HOWEVER, that all
Arrangement Consideration shall be in the form of shares of Parent Class A
Stock.

                                   ARTICLE V.

                         Representations and Warranties

         5.1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. Except as set forth
in the corresponding sections or subsections of the disclosure letter delivered
to Parent by the Company on or prior to entering into this Agreement (the
"COMPANY DISCLOSURE LETTER"), the Company hereby represents and warrants to
Parent that as of the date hereof and as of the Closing Date (except to the
extent such representations and warranties expressly speak as of an earlier
date):

         (a) ORGANIZATION, GOOD STANDING AND QUALIFICATION. Each of the Company
and its Subsidiaries is a corporation or other entity duly organized, validly
existing and in good standing under the laws of its respective jurisdiction of
organization and has all requisite corporate or similar power and authority to
own and operate its properties and assets and to carry on its business as
presently conducted and is qualified to do business and is in good standing as a
foreign corporation or other entity in each jurisdiction where the ownership or
operation of its assets or properties or conduct of its



                                       6
<PAGE>


business requires such qualification, except where the failure to be so
organized, qualified or in good standing, or to have such power or authority
when taken together with all other such failures, is not reasonably likely to
have a Material Adverse Effect (as defined below). The Company has made
available to Parent a complete and correct copy of the Company's and its
Subsidiaries' certificates of incorporation, memorandum of association and
bye-laws (or other constitutional documents), each as amended to date. The
Company's and its Subsidiaries' certificates of incorporation, memorandum of
association and bye-laws (or other constitutional documents) so delivered are in
full force and effect. The Company has made available to Parent the books and
records of the Company and its Subsidiaries. The books and records of the
Company and its Subsidiaries accurately reflect in all material respects any
transactions entered into by the Company or its Subsidiaries. Section 5.1(a) of
the Company Disclosure Letter contains a correct and complete list of each
jurisdiction where the Company and each of its Subsidiaries is organized and
qualified to do business.

         As used in this Agreement, the term (i) "SUBSIDIARY" means, with
respect to the Company or Parent, as the case may be, any entity, whether
incorporated or unincorporated, of which at least a majority of the securities
or ownership interests having by their terms ordinary voting power to elect a
majority of the board of directors or other persons performing similar functions
is directly or indirectly owned or controlled by such party or by one or more of
its respective Subsidiaries or by such party and any one or more of its
respective Subsidiaries and (ii) "MATERIAL ADVERSE EFFECT" means a material
adverse effect on the financial condition, properties, prospects, business or
results of operations of the Company and its Subsidiaries taken as a whole.

         (b) CAPITAL STRUCTURE. The authorized shares of the Company consists of
24,000,000 Common Shares, of which 17,043,900 shares were outstanding as of the
close of business on March 6, 2000, 100 Class A Restricted Voting Shares, par
value $1.50 per share ("CLASS A SHARES"), of which no shares were outstanding as
of the close of business on March 6, 2000, and 2,000 Class B Shares, of which
1,000 shares were outstanding as of the close of business on March 6, 2000. All
of the outstanding Shares have been duly authorized and are validly issued,
fully paid and nonassessable. The Company has no Shares or Class A Shares
reserved for issuance, except that, as of March 6, 2000, there were 1,908,199
Common Shares reserved for issuance pursuant to the Company's 1998 Share Option
and Incentive Plan and the 1997 TeleBermuda International Limited Directors,
Executives, Senior Management and Senior Staff Stock Option Plan (the "STOCK
PLANS") or otherwise. The Company Disclosure Letter contains a correct and
complete list of each outstanding option to purchase Common Shares (each a
"COMPANY OPTION"), including the holder, date of grant, exercise price and
number of Common Shares subject thereto. Each of the outstanding shares of
capital stock or other securities of each of the Company's Subsidiaries is duly
authorized, validly issued, fully paid and nonassessable and, except for
directors' qualifying shares, owned by a direct or indirect wholly-owned
Subsidiary of the Company, free and clear of any lien, pledge, security
interest, claim or other encumbrance ("LIENS"), except for those liens created
pursuant to the Credit Agreement or any Security Document (as such terms are
defined below). Except as set



                                       7
<PAGE>


forth in Section 5.1(b) of the Company Disclosure Letter, there are no
preemptive or other outstanding rights, options, warrants, conversion rights,
stock appreciation rights, redemption rights, repurchase rights, agreements,
arrangements, calls, commitments or rights of any kind that obligate the Company
or any of its Subsidiaries to issue or sell any shares of capital stock or other
securities of the Company or any of its Subsidiaries or any securities or
obligations convertible or exchangeable into or exercisable for, or giving any
Person a right to subscribe for or acquire, any securities of the Company or any
of its Subsidiaries, and no securities or obligations evidencing such rights are
authorized, issued or outstanding. The Company does not have outstanding any
bonds, debentures, notes or other obligations the holders of which have the
right to vote (or convertible into or exercisable for securities having the
right to vote) with the shareholders of the Company on any matter ("VOTING
DEBT"). For purposes of this Agreement, (i) "CREDIT AGREEMENT" means that
certain Credit Agreement dated as of July 14, 1999, among GlobeNet
Communications Holdings Ltd., Toronto Dominion (Texas) Inc., as administrative
agent, and certain other parties, as amended; and (ii) "SECURITY DOCUMENT" has
the meaning provided in the Credit Agreement.

         (c) CORPORATE AUTHORITY; APPROVAL AND FAIRNESS. (i) The Company has all
requisite corporate power and authority and has taken all corporate action
necessary in order to execute, deliver and perform its obligations under this
Agreement and to consummate, subject only to approval of the Arrangement by a
majority in number representing 75% in value of the holders of the outstanding
Common Shares and approval of the Scheme of Arrangement by a majority in number
representing 75% in value of the holders of the outstanding Class B Shares (the
"COMPANY REQUISITE VOTE"), the Arrangement. This Agreement is a valid and
binding agreement of the Company enforceable against the Company in accordance
with its terms, subject to bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and similar laws of general applicability relating to
or affecting creditors' rights and to general equity principles (the "BANKRUPTCY
AND EQUITY EXCEPTION").

         (ii) The board of directors of the Company has unanimously approved the
Arrangement and the other transactions contemplated hereby, other than Mark
Pelson who abstained from voting on such matters. It is agreed and understood
that such opinion is for the benefit of the Company's Board of Directors and may
not be relied on by Parent.

         (d) GOVERNMENTAL FILINGS; NO VIOLATIONS. (i) Except as set forth in
Section 5.1(d) of the Company Disclosure Letter, no notices, reports or other
filings are required to be made by the Company with, nor are any consents,
registrations, approvals, permits or authorizations required to be obtained by
the Company from, any domestic or foreign governmental or regulatory authority,
agency, commission, body or other governmental entity ("GOVERNMENTAL ENTITY"),
in connection with the execution and delivery of this Agreement by the Company
and the consummation by the Company of the Arrangement and the other
transactions contemplated hereby and thereby.



                                       8
<PAGE>


         (ii) Except as provided in Section 5.1(d)(ii) of the Company Disclosure
Letter, the execution, delivery and performance of this Agreement by the Company
does not, and the consummation by the Company of the Arrangement and the other
transactions contemplated hereby will not, constitute or result in (A) a breach
or violation of, or a default under, the memorandum of association or bye-laws
of the Company or the comparable governing instruments of any of its
Subsidiaries, (B) a breach or violation of, or a default under, the acceleration
of any obligations or the creation of a Lien on the assets of the Company or any
of its Subsidiaries (with or without notice, lapse of time or both) pursuant to,
any agreement, lease, license, contract, note, mortgage, indenture, arrangement
or other obligation with a term of six or more months after the date hereof or
involving payments of $50,000 or more after the date hereof ("CONTRACTS")
binding upon the Company or any of its Subsidiaries or any Law (as defined in
Section 5.1(i)) or governmental or non-governmental permit or license to which
the Company or any of its Subsidiaries is subject or (C) any change in the
rights or obligations of any party under any of the Contracts. Section 5.1(d) of
the Company Disclosure Letter sets forth, among other things, a correct and
complete list of Contracts of the Company and its Subsidiaries pursuant to which
consents or waivers are or may be required prior to consummation of the
transactions contemplated by this Agreement.

         (e) COMPANY REPORTS; FINANCIAL STATEMENTS. The Company has delivered to
Parent each registration statement, report, proxy statement or information
statement prepared by it since December 31, 1999 (the "AUDIT DATE"), each in the
form (including exhibits, annexes and any amendments thereto) filed with the
Securities and Exchange Commission (the "SEC") (collectively, including any such
reports filed subsequent to the date hereof and as amended, the "COMPANY
REPORTS"). As of their respective dates (or, if amended, as of the date of such
amendment), the Company Reports did not, and any Company Reports filed with the
SEC subsequent to the date hereof will not, contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements made therein, in light of the circumstances in
which they were made, not misleading. Each of the consolidated balance sheets
included in or incorporated by reference into the Company Reports (including the
related notes and schedules) fairly presents, or will fairly present, the
consolidated financial position of the Company and its Subsidiaries as of its
date and each of the consolidated statements of shareholders' equity, of
operations and of cash flows included in or incorporated by reference into the
Company Reports (including any related notes and schedules) fairly presents, or
will fairly present, the results of operations, cash flows and shareholders'
equity, as the case may be, of the Company and its Subsidiaries for the periods
set forth therein (subject, in the case of unaudited statements, to notes and
normal year-end audit adjustments that will not be material in amount or
effect), in each case in accordance with generally accepted accounting
principles ("GAAP") consistently applied during the periods involved, except as
may be noted therein.

         (f) ABSENCE OF CERTAIN CHANGES. Except as provided in Section 5.1(f) of
the Company Disclosure Letter, since the Audit Date the Company and its
Subsidiaries



                                       9
<PAGE>


have conducted their respective businesses in all material respects, and have
not engaged in any material transaction other than according to, the ordinary
and usual course of such businesses and there has not been (i) any change in the
financial condition, properties, prospects, business or results of operations of
the Company and its Subsidiaries or any development or combination of
developments of which management of the Company has knowledge that, individually
or in the aggregate, has had or is reasonably likely to have a Material Adverse
Effect other than any change, development or combination of developments which
apply generally to the fiber-optic submarine cable business; (ii) any material
damage, destruction or other casualty loss with respect to any material asset or
property owned, leased or otherwise used by the Company or any of its
Subsidiaries, whether or not covered by insurance; (iii) any declaration,
setting aside or payment of any dividend or other distribution in cash, stock or
property in respect of the capital stock of the Company, except for dividends or
other distributions on its capital stock publicly announced prior to the date
hereof and except as expressly permitted hereby; (iv) any change by the Company
in accounting principles, practices or methods; (v) issued or sold any shares of
any class of its capital stock, or any securities convertible into or
exchangeable for any such shares, or issued, sold, granted or entered into any
subscriptions, options, warrants, conversion or other rights, agreements,
commitments, arrangements or understandings of any kind, contingently or
otherwise, to purchase or otherwise acquire any such shares or any securities
convertible into or exchangeable for any such shares; (vi) incurred any
indebtedness for borrowed money, issued or sold any debt securities or prepaid
any debt except for borrowings and repayments in the ordinary course of
business; (vii) assigned, mortgaged, pledged or otherwise subjected to any lien,
any of its assets, except assignments to any Subsidiary or in the ordinary
course of business; (viii) forgiven, canceled, compromised, waived or released
any debts, claims or rights, except for debts, claims and rights forgiven,
canceled, compromised, waived or released which are immaterial or in the
ordinary course of business consistent with past practice; (ix) except in the
ordinary course of business, paid any bonus to any director, officer, manager or
employee or granted to any director, officer, manager or employee, any other
increase in compensation in any form; (x) entered into, adopted or amended any
employment, consulting, retention, change-in-control, collective bargaining,
bonus or other incentive compensation, profit-sharing, health or other welfare,
stock option or other equity, pension, retirement, vacation, severance, deferred
compensation or other employment, compensation or benefit plan, policy,
agreement, trust, fund or arrangement for the benefit of any officer, director
or employee; (xi) amended its memorandum of association or bye-laws; (xii)
incurred, assumed, guaranteed or otherwise became, directly or indirectly liable
with respect to any liability or obligation (whether absolute, accrued,
contingent or otherwise and whether direct or indirect, or as guarantor or
otherwise with respect to any liability or obligation of any other Person) in
excess of (A) $100,000 in each case, other than purchase orders and payroll
obligations in the ordinary course of business, or (B) except in the ordinary
course of business $250,000 in the aggregate at any one time outstanding; (xiii)

the aggregate, other than in the ordinary course of business consistent with
past practice; or (xiv) instituted, settled or agreed to settle any litigation,
action or



                                       10
<PAGE>


proceeding before any court or government body, other than in the ordinary
course of business consistent with past practice. Since the Audit Date, there
has not been any increase in the compensation payable or that could become
payable by the Company or any of its Subsidiaries to officers or key employees
or any amendment of any of the Compensation and Benefit Plans (as defined in
Section 5.1(h)(i)) other than as provided in Section 5.1(f) of the Company
Disclosure Letter or increases or amendments in the ordinary course.

         (g) LITIGATION AND LIABILITIES. (i) Except as disclosed in Section
5.1(g) of the Company Disclosure Letter, as of the date of this Agreement there
are no civil, criminal or administrative actions, suits, claims, hearings,
investigations or proceedings ("ACTIONS") pending or, to the knowledge of the
officers of the Company, threatened against the Company or any of its Affiliates
and as of the Effective Time there will not be any civil, criminal or
administrative Actions pending or, to the knowledge of the officers of the
Company, threatened against the Company or any of its Affiliates that are
material to the Company. Neither the Company nor any of its Subsidiaries is
subject to any settlement or similar agreement with any Governmental Entity, or
to any order, judgment, decree, injunction or award of any Governmental Entity
that, individually or in the aggregate, could reasonably be expected to have or
result in a Material Adverse Effect.

         (ii) Neither the Company nor any of its Subsidiaries has any
liabilities or obligations of any nature, whether known, unknown, absolute,
accrued, contingent or otherwise and whether due or to become due, except (A) as
set forth in Section 5.1(g) of the Company Disclosure Letter, (B) as and to the
extent disclosed on and adequately reserved against in the balance sheet of the
Company as of the Audit Date, which are included in the Company Reports, or (C)
for liabilities and obligations that (I) were incurred after December 31, 1999
in the ordinary course of business and are not prohibited by this Agreement and
(II) individually and in the aggregate have not had a Material Adverse Effect
and could not reasonably be expected to have or result in a Material Adverse
Effect.

         (h) EMPLOYEE BENEFITS.

         (i) A copy of each bonus, deferred compensation, pension, retirement,
profit-sharing, thrift, savings, employee stock ownership, stock bonus, stock
purchase, restricted stock, stock option, employment, termination, severance,
compensation, medical, health or other plan, agreement, policy or arrangement
that covers employees, directors, former employees or former directors of the
Company and its Subsidiaries (the "COMPENSATION AND BENEFIT PLANS") and any
trust agreement or insurance contract forming a part of such Compensation and
Benefit Plans has been made available to Parent prior to the date hereof. The
Compensation and Benefit Plans are listed in Section 5.1(h) of the Company
Disclosure Letter and any "change of control" or similar provisions therein are
specifically identified in Section 5.1(h) of the Company Disclosure Letter.



                                       11
<PAGE>


         (ii) All Compensation and Benefit Plans are in substantial compliance
with all applicable law. None of the Compensation and Benefit Plans is subject
to the Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
except as set forth in Section 5.1(b)(ii) of the Company Disclosure Letter.
Wherever required under applicable law or customary under applicable practice,
the Compensation and Benefit Plans are approved by the relevant taxation and
other governmental authorities such as to enable the Company, its Subsidiaries
and the beneficiaries under the Compensation and Benefits Plans and, in the case
of a Funded Benefit Plan (as defined below), the assets held for the purposes of
the Compensation and Benefits Plans, to enjoy the most favorable taxation status
possible, and, to the knowledge of the officers of the Company, there is no
ground on which such approval may be withdrawn or cease to apply. There is no
pending or, to the knowledge of the officers of the Company, threatened material
litigation relating to the Compensation and Benefit Plans.

         (iii) Neither the Company nor any entity which is considered one
employer with the Company under Section 4001 of ERISA has ever maintained or
contributed to any employee benefit plan subject to Title IV of ERISA. All
payments, deductions from wages, reports, returns and similar documents with
respect to the Compensation and Benefit Plan required to be filed with or paid
to any governmental authority or Compensation and Benefit Plan or distributed to
any Compensation and Benefit Plan participant have duly and timely filed, paid
or distributed.

         (iv) Each Compensation and Benefit Plan in or under which assets are
set aside in advance relating to the intended or promised benefits, other than a
"defined contribution plan" within the meaning of Section 3(34) of ERISA
("FUNDED BENEFIT PLAN") has been valued actuarially in the last three years
("VALUATION"). The last Valuation of each Funded Benefit Plan showed that the
Funded Benefit Plan was fully funded on the assumptions and methods adopted for
that Valuation. The assumptions and methods used in the last Valuation of each
Funded Benefit Plan were in accordance with applicable law and local practice
and were reasonable assumptions having regard to the nature and circumstances of
the Funded Benefit Plan.

         (v) In relation to a Compensation and Benefit Plan which is a Funded
Benefit Plan, all contributions and other payments due from the participating
employers and employees have been paid to the Compensation and Benefit Plan and
nothing has occurred or become known since the effective date of the Valuation
which might reasonably be expected to cause the result of an actuarial valuation
carried out at the date of this Agreement, adopting the same actuarial methods
and assumptions as were adopted for the purpose of the Valuation, to be
materially different from the result of the Valuation.

         (vi) In relation to a Compensation and Benefit Plan that is not a
Funded Benefit Plan, the Company or a Subsidiary maintains a book reserve in
respect of the Compensation and Benefit Plan to the extent required by
applicable law and generally accepted best local accounting practices and in any
event sufficient to provide all benefits under such Compensation and Benefit
Plan.



                                       12
<PAGE>


         (vii) Except for the Stock Plans and agreements set forth in Section
5.1(h) of the Company Disclosure Letter, the consummation of the Arrangement and
the other transactions contemplated by this Agreement will not (x) entitle any
employees of the Company or its Subsidiaries to severance pay, (y) accelerate
the time of payment or vesting or trigger any payment or funding (through a
grantor trust or otherwise) of compensation or benefits under, increase the
amount payable or trigger any other material obligation pursuant to, any of the
Compensation and Benefit Plans or (z) result in any breach or violation of, or a
default under, any of the Compensation and Benefit Plans.

         (i) COMPLIANCE WITH LAWS; PERMITS. (i) As of the date of this
Agreement, the businesses of each of the Company and its Subsidiaries have not
been, and are not being, conducted in violation of any federal, state, local or
foreign law, statute, ordinance, rule, regulation, judgment, order, injunction,
decree, arbitration award, agency requirement, license or permit of any
Governmental Entity (collectively, "LAWS") and as of the Effective Time, the
businesses of each of the Company and its Subsidiaries will not be conducted in
violation of any federal, state, local or foreign Laws except for any violation,
which individually or in the aggregate, would not be material to the Company.
Except as set forth in the Company Reports filed prior to the date hereof, no
investigation or review by any Governmental Entity with respect to the Company
or any of its Subsidiaries is pending or, to the knowledge of the officers of
the Company, threatened, nor has any Governmental Entity indicated an intention
to conduct the same. To the knowledge of the officers of the Company, no
material change is required in the Company's or any of its Subsidiaries'
processes, properties or procedures in connection with any Laws, and the Company
has not received any notice or communication of any material noncompliance with
any Laws that has not been cured as of the date hereof. Except as set forth in
Section 5.1(i) of the Company Disclosure Letter, as of the date of this
Agreement, the Company and its Subsidiaries each has all and as of the Effective
Time, the Company and its Subsidiaries each will have all permits, licenses,
franchises, variances, exemptions, orders and other governmental authorizations,
consents and approvals necessary to conduct its business as then conducted,
except where the failure to have any of the foregoing would not be material to
the Company.

         (ii) The Company and each of its Subsidiaries holds, and is qualified
and eligible to hold, all material licenses, permits and other authorizations
issued by the Federal Communications Commission (the "FCC") to such entity for
the operation of their respective businesses, all of which are set forth in
Section 5.1(i) of the Company Disclosure Letter (the "COMPANY FCC LICENSES").
The Company FCC Licenses are valid and in full force and effect and neither the
Company nor any of its Subsidiaries is or has been delinquent in payment on or
in default under any installment obligation owed to the United States Treasury
in connection with the Company FCC Licenses. As used herein, the term "full
force and effect" means that (A) the orders issuing the Company FCC Licenses
have become effective, (B) no stay of effectiveness of such orders has been
issued by the FCC, and (C) the Company FCC Licenses have not been invalidated by
any



                                       13
<PAGE>


subsequent published FCC action. All material reports and applications required
by the Communications Act of 1934, as amended (the "COMMUNICATIONS ACT"), or
required to be filed with the FCC by the Company or any of its Subsidiaries have
been filed and are accurate and complete in all material respects. The Company
and its Subsidiaries are, and have been, in compliance in all material respects
with, and the communications systems operated pursuant to the Company FCC
Licenses are and have been operated in compliance in all material respects with,
the Communications Act. There is not pending as of the date hereof any
application, petition, objection, pleading or proceeding with the FCC or any
public service commission or similar body having jurisdiction or authority over
the communications operations of the Company or any of its Subsidiaries which
questions the validity of or contests any Company FCC License or which presents
a substantial risk that, if accepted or granted, or concluded adversely, could
result in (as applicable) the revocation, cancellation, suspension, dismissal,
denial or any materially adverse modification of any Company FCC License or
imposition of any substantial fine or forfeiture against the Company or any of
its Subsidiaries except as set forth in Section 5.1(i) of the Company Disclosure
Letter. No fact is known to the Company or its Subsidiaries which if known by a
Governmental Entity of competent jurisdiction would present a substantial risk
that any Company FCC License could be revoked, cancelled, suspended or
materially adversely modified or that any substantial fine or forfeiture could
be imposed against the Company or any of its Subsidiaries.

         (iii) Each of the Company and its Subsidiaries has complied with the
United States Foreign Corrupt Practices Act and neither of them nor any Person
controlled by either of them, nor, to the knowledge of the officers of the
Company, any Person acting on behalf of any of the foregoing has directly or
indirectly offered or promised to transfer, or transferred or authorized the
transfer of, any money or thing of value to any governmental official, political

     6.2. ACQUISITION PROPOSALS. The Company agrees that neither it nor any of
its Subsidiaries nor any of the officers and directors of it or its Subsidiaries
shall, and that it shall direct and use its best efforts to cause its and its
Subsidiaries' employees, agents and representatives (including any investment
banker, attorney or accountant retained by it or any of its Subsidiaries) not
to, directly or indirectly, initiate, solicit, encourage or otherwise facilitate
any inquiries or the making of any proposal or offer with respect to a plan of
arrangement, merger, amalgamation, reorganization, share exchange, consolidation
or similar transaction involving, or any purchase of all or 15% or more of the
assets or any equity securities of, it or any of its Subsidiaries (any such
proposal or offer being hereinafter referred to as an "ACQUISITION PROPOSAL").
The Company further agrees that neither it nor any of its Subsidiaries nor any
of the officers and directors of it or its Subsidiaries shall, and that it shall
direct and use its best efforts to cause its and its Subsidiaries' employees,
agents and representatives (including any investment banker, attorney or
accountant retained by it or any of its Subsidiaries) not to, directly or
indirectly, engage in any negotiations concerning, or provide any confidential
information or data to, or have any discussions with, any Person relating to an
Acquisition Proposal, or otherwise facilitate any effort or attempt to make or
implement an Acquisition Proposal; provided, however, that nothing contained in
this Agreement shall prevent the Company or its Board of Directors from
complying with Rule 14e-2 promulgated under the Securities Exchange Act of 1934,
as amended (the "EXCHANGE ACT") with regard to an Acquisition Proposal. The
Company agrees that it will immediately cease and cause to be terminated any
existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any Acquisitions Proposal. The Company agrees that it
will take the necessary steps to promptly inform the individuals or entities
referred to in the first sentence hereof of the obligations undertaken in this
Section 6.2 and in the Confidentiality Agreement (as defined in Section 9.7).
The Company agrees that it will notify Parent immediately if any such inquiries,
proposals or offers are received by, any such information is requested from, or
any such discussions or negotiations are sought to be initiated or continued
with, any of its representatives indicating, in connection with such notice, the
name of such Person and the material terms and conditions of any proposals or
offers and thereafter shall keep Parent informed, on a current basis, on the
status and terms of any such proposals or offers and the status of any such
discussions or negotiations. The Company also agrees that it will promptly
request each Person that has heretofore executed a confidentiality agreement in
connection with its consideration of acquiring it or any of its Subsidiaries to
return all confidential information heretofore furnished to such Person by or on
behalf of it or any of its Subsidiaries.

     6.3. INFORMATION SUPPLIED. The Company and Parent each agrees, as to itself
and its Subsidiaries, that none of the information supplied or to be supplied by
it or its Subsidiaries for inclusion in the Company Proxy Statement (as defined
below) will at the date of mailing to shareholders and at the times of the
meeting of shareholders of the Company to be held in connection with the
Arrangement, contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they were


                                       25

<PAGE>

made, not misleading. The Company will ensure that the Company Proxy Statement
complies with all applicable Laws. The "COMPANY PROXY STATEMENT" shall mean the
notice of the special meeting of holders of Shares convened pursuant to an order
of the Bermuda Court to be sent to holders of Shares to consider this Agreement
and the Arrangement and the accompanying explanatory statement in connection
with such meeting, as supplemented or otherwise modified.

     6.4. IMPLEMENTATION STEPS. The Company will take, in accordance with
applicable Law and its memorandum of association and bye-laws, all action
necessary to (i) apply in a manner acceptable to Parent, under Section 99 of the
Bermuda Act for the "INTERIM ORDER" (as defined in the Scheme of Arrangement),
and thereafter proceed with and use reasonable best efforts to obtain the
Interim Order, (ii) subject to obtaining the Interim Order, convene a meeting of
holders of Shares (the "COMPANY SHAREHOLDERS MEETING") as promptly as
practicable to consider and vote upon the approval of the Arrangement, (iii)
subject to obtaining approval of the Company's shareholders as required by the
Bermuda Act, use reasonable best efforts to pursue the application to the
Bermuda Court for the Final Order, and (iv) subject to obtaining the Final Order
and the satisfaction or waiver of the other conditions contained in this
Agreement, send to the Bermuda Registrar, for registration by the Bermuda
Registrar, the Final Order of the Bermuda Court and such other documents as may
be required in connection therewith under the Bermuda Act to give effect to the
Arrangement. The Company's board of directors shall recommend approval of this
Agreement and the Arrangement and shall take all lawful action to solicit such
approval, it being understood that the Company's board of directors may withdraw
such approval if it determines in good faith, after consultation with and based
on the advice of its outside counsel, that it is necessary to do so in order to
comply with its fiduciary duties to the shareholders of the Company, provided
that in no event may the Company's board of directors fail to convene the
Company Shareholders Meeting.

     6.5. FILINGS; OTHER ACTIONS; NOTIFICATION. (a) The Company shall promptly
prepare the Company Proxy Statement. Parent shall use its reasonable best
efforts to obtain prior to the Effective Date all necessary U.S. federal
securities law, U.S. state securities law or "blue sky" permits and approvals
required in connection with the Arrangement and to consummate the other
transactions contemplated by this Agreement and will pay all expenses incident
thereto.

     (b) Parent and the Company shall use reasonable best efforts to prepare all
documents and obtain all orders required from the applicable Canadian securities
authorities to permit (i) the issuance of Parent Class A Stock pursuant to the
Arrangement in accordance with the applicable Canadian securities laws and the
resale thereof without any hold period or requirement that Parent be a
"reporting issuer" under applicable Canadian securities laws for any particular
period, and (ii) the issuance of the Parent Class A Stock issued from time to
time upon the exercise of the Company Options.

     (c) The Company and Parent shall cooperate with each other and use (and
shall cause their respective Subsidiaries to use) their respective reasonable
best efforts


                                       26
<PAGE>

to take or cause to be taken all actions, and do or cause to be done all things,
necessary, proper or advisable on its part under this Agreement and applicable
Laws to consummate and make effective the Arrangement and the other transactions
contemplated by this Agreement as soon as practicable, including preparing and
filing as promptly as practicable all documentation to effect all necessary
notices, reports and other filings and to obtain as promptly as practicable all
consents, registrations, approvals, permits and authorizations necessary or
advisable to be obtained from any third party and/or any Governmental Entity in
order to consummate the Arrangement or any of the other transactions
contemplated by this Agreement; provided, however, that nothing in this Section
6.5 shall require, or be construed to require, Parent to proffer to, or agree
to, sell or hold separate and agree to sell, before or after the Effective Time,
any assets, businesses, or interest in any assets or businesses of Parent, the
Company or any of their respective Affiliates (or to consent to any sale, or
agreement to sell, by the Company of any of its assets or businesses) or to
agree to any material changes or restriction in the operations of any such
assets or businesses. Subject to applicable laws relating to the exchange of
information, Parent and the Company shall have the right to review in advance,
and to the extent practicable each will consult the other on, all the
information relating to Parent or the Company, as the case may be, and any of
their respective Subsidiaries, that appear in any filing made with, or written
materials submitted to, any third party and/or any Governmental Entity in
connection with the Arrangement and the other transactions contemplated by this
Agreement. In exercising the foregoing right, each of the Company and Parent
shall act reasonably and as promptly as practicable.

     (d) As promptly as practicable after the execution and delivery of this
Agreement, Parent and the Company shall prepare all appropriate applications for
FCC approval, and such other documents as may be required, with respect to the
transfer of control of the Company to Parent (collectively, the "FCC
APPLICATIONS"). Not later than the tenth business day following execution and
delivery of this Agreement, the Company and Parent will exchange with each other
their respective completed portions of the FCC Applications. Not later than the
fifteenth business day following the execution and delivery of this Agreement,
the Company and Parent shall file, or cause to be filed, the FCC Applications.
No party hereto shall knowingly take, or fail to take, any action if the intent
or reasonably anticipated consequence of such action or failure to act is, or
would be, to cause the FCC not to grant approval of the FCC Applications or
delay either such approval or the consummation of the transfer of control of the
Company. Parent and the Company shall each pay one-half (1/2) of any FCC fees,
if applicable, in connection with the filing or granting of approval of the FCC
Applications. Each of Parent and the Company shall bear its own expenses in
connection with the preparation and prosecution of the FCC Applications, Parent
and the Company shall each use all commercially reasonable efforts to prosecute
the FCC Applications in good faith and with due diligence before the FCC and in
connection therewith shall take such action or actions as may be necessary or
reasonably required in connection with the FCC Applications.


                                       27
<PAGE>

     (e) The Company and Parent each shall, upon request by the other, furnish
the other with all information concerning itself, its Subsidiaries, directors,
officers and shareholders and such other matters as may be reasonably necessary
or advisable in connection with the Company Proxy Statement or any other
statement, filing, notice or application made by or on behalf of Parent, the
Company or any of their respective Subsidiaries to any third party and/or any
Governmental Entity in connection with the Arrangement and the transactions
contemplated by this Agreement.

     (f) The Company and Parent each shall keep the other apprised of the status
of matters relating to completion of the transactions contemplated hereby,
including promptly furnishing the other with copies of notices or other
communications received by Parent or the Company, as the case may be, or any of
its Subsidiaries, from any third party and/or any Governmental Entity with
respect to the Arrangement and the other transactions contemplated by this
Agreement. The Company shall give prompt notice to the Parent of any change that
is reasonably likely to result in a Material Adverse Effect.

     6.6. TAXATION. Parent agrees to enter into an election under Section 85 of
the Income Tax Act, Canada ("CANADIAN ITA") whereby it would jointly file a Form
T2057 or T2058 with any of the Company's shareholders resident in Canada for
purposes of the Canadian ITA that so desire at an amount as determined by the
particular shareholder, subject to the limitations set out in the Canadian ITA.

     6.7. ACCESS. Upon reasonable notice, and except as may otherwise be
required by applicable law, the Company shall (and shall cause its Subsidiaries
to) afford the Parent's officers, employees, counsel, accountants and other
authorized representatives ("REPRESENTATIVES") reasonable access, during normal
business hours throughout the period prior to the Effective Time, to its
properties, books, contracts and records and, during such period, each shall
(and shall cause its Subsidiaries to) furnish promptly to the other all
information concerning its business, properties and personnel as may reasonably
be requested, provided that no investigation pursuant to this Section shall
affect or be deemed to modify any representation or warranty made by the Company
and provided, further, that the foregoing shall not require the Company to
permit any inspection, or to disclose any information, that in the reasonable
judgment of the Company would result in the disclosure of any trade secrets of
third parties or violate any of its obligations with respect to confidentiality
if the Company shall have used reasonable best efforts to obtain the consent of
such third party to such inspection or disclosure. All requests for information
made pursuant to this Section shall be directed to an executive officer of the
Company or Parent, as the case may be, or such Person as may be designated by
either of its officers, as the case may be. All such information shall be
governed by the terms of the Confidentiality Agreement.

     6.8. AFFILIATES. Prior to the date of the Company Shareholders Meeting,
Parent shall deliver to the Company a list of names and addresses of those
Persons who will be, in the opinion of Parent, as of the time of the Company
Shareholders Meeting referred to in Section 6.4, "affiliates" of the Company
within the meaning of Rule 145


                                       28
<PAGE>

under the Securities Act. The Company shall provide to Parent such information
and documents as Parent shall reasonably request for purposes of preparing such
list. There shall be added to such list the names and addresses of any other
Person subsequently identified by either Parent or the Company as a Person who
may be deemed to be such an affiliate of the Company; provided, however, that no
such Person identified by Parent shall be added to the list of affiliates of the
Company if Parent shall receive from the Company, on or before the date of the
Company Shareholders Meeting, an opinion of counsel reasonably satisfactory to
Parent to the effect that such Person is not such an affiliate. The Company
shall exercise its reasonable best efforts to deliver or cause to be delivered
to Parent, prior to the date of the Company Shareholders Meeting, from each
affiliate of the Company identified in the foregoing list (as the same may be
supplemented as aforesaid), a letter dated as of the Closing Date substantially
in the form attached as Exhibit A (the "AFFILIATES LETTER"). The certificates
representing Parent Class A Stock received by such affiliates shall bear a
customary legend regarding applicable Securities Act restrictions and the
provisions of this Section.

     6.9. STOCK EXCHANGE LISTING AND DELISTING. Parent shall use its reasonable
best efforts to cause the Parent Class A Stock to be issued in the Arrangement
to be approved for listing on the NASDAQ and The Toronto Stock Exchange prior to
the Closing Date, subject to official notice of issuance. Parent shall use its
reasonable best efforts to cause the Common Shares to be delisted from the
Bermuda Stock Exchange as soon as practicable following the Effective Time.

     6.10. PUBLICITY. The initial press release shall be a joint press release
and thereafter the Company and Parent shall not, nor shall they permit their
respective Affiliates to, issue any press release or otherwise make any public
announcement or filing with any Governmental Entity in respect of this Agreement
or the transactions contemplated hereby, without the prior approval of the other
party, except as may be required by law or by obligations pursuant to any
listing agreement with or rules of any national securities exchange.

     6.11. BENEFITS. (a) STOCK OPTIONS.

     (i) At the Effective Time, each Company Option, whether vested or unvested,
shall be deemed to constitute an option to acquire, on the same terms and
conditions as were applicable under such Company Option, the same number of
shares of Parent Class A Stock as the holder of such Company Option would have
been entitled to receive pursuant to the Arrangement had such holder exercised
such option in full immediately prior to the Effective Time (rounded to the
nearest whole number, with .50 being rounded downward), at a price per share
(rounded to the nearest whole cent with .50 rounded downward) equal to (y) the
aggregate exercise price for the Common Shares otherwise purchasable pursuant to
such Company Option divided by (z) the number of full shares of Parent Class A
Stock deemed purchasable pursuant to such Company Option in accordance with the
foregoing. At or prior to the Effective Time, the Company shall make


                                       29
<PAGE>

all necessary arrangements with respect to the Stock Plans to permit the
assumption of the unexercised Company Options by Parent pursuant to this
Section.

     (ii) Effective at the Effective Time, Parent shall assume each Company
Option in accordance with its terms and, where applicable, the Stock Plan under
which it was issued. At or prior to the Effective Time, Parent shall take all
corporate action necessary to reserve for issuance a sufficient number of shares
of Parent Class A Stock for delivery upon exercise of Company Options assumed by
it in accordance with this Section.

     (b) EMPLOYEE BENEFITS. Parent agrees to consider all employees of the
Company and its Subsidiaries as of the date hereof for continued employment
after the Effective Time by Parent or any of its Subsidiaries and Parent will
make its employee long term option incentive program available to all employees
of the Company and its Subsidiaries who become direct or indirect employees of
Parent. Parent shall recognize all prior service of such employees with the
Company and its Subsidiaries for purposes of determining eligibility to
participate and vesting under any employee benefit plan maintained by Parent,
the Company or any of their Subsidiaries after the Effective Time. Parent shall,
and shall cause the Company to, honor all employee benefit obligations to
current and former employees of the Company and its Subsidiaries under the
Compensation and Benefit Plans and all employee severance plans (or policies),
employment and severance agreements in existence prior to the date hereof.

     6.12. EXPENSES. Parent shall pay all charges and expenses, including those
of the Exchange Agent, in connection with the transactions contemplated in
Article IV. Except as otherwise provided in Section 8.5(b), whether or not the
Arrangement is consummated, all costs and expenses incurred in connection with
this Agreement and the Arrangement and the other transactions contemplated by
this Agreement shall be paid by the party incurring such expense.

     6.13. INDEMNIFICATION. (a) From and after the Effective Time, Parent agrees
that it will indemnify and hold harmless each present and former director and
officer of the Company (when acting in such capacity) determined as of the
Effective Time (the "INDEMNIFIED PARTIES") against any costs or expenses
(including reasonable attorneys' fees), judgments, fines, losses, claims,
damages or liabilities (collectively, "COSTS") incurred in connection with any
claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of matters existing or occurring at
or prior to the Effective Time, whether asserted or claimed prior to, at or
after the Effective Time, to the fullest extent that the Company would have been
permitted under Bermuda law and its memorandum of association or bye-laws or
pursuant to other agreements in effect on the date hereof to indemnify such
Person (and Parent shall also advance expenses as incurred to the fullest extent
permitted under applicable law PROVIDED the Person to whom expenses are advanced
provides an undertaking to repay such advances if it is ultimately determined
that such Person is not entitled to indemnification).


                                       30
<PAGE>

     (b) Any Indemnified Party wishing to claim indemnification under paragraph
(a) of this Section 6.13, upon learning of any such claim, action, suit,
proceeding or investigation, shall promptly notify Parent thereof, using
reputable counsel, but the failure to so notify shall not relieve Parent of any
liability it may have to such Indemnified Party if such failure does not
materially prejudice the indemnifying party. In the event of any such claim,
action, suit, proceeding or investigation (whether arising before or after the
Effective Time), (i) Parent shall have the right to assume the defense thereof,
using reputable counsel, and Parent shall not be liable to such Indemnified
Parties for any legal expenses of other counsel or any other expenses
subsequently incurred by such Indemnified Parties in connection with the defense
thereof, except that if Parent elects not to assume such defense or counsel for
the Indemnified Parties advises that there are issues which raise conflicts of
interest between Parent and the Indemnified Parties, the Indemnified Parties may
retain counsel satisfactory to them, and Parent shall pay all reasonable fees
and expenses of such counsel for the Indemnified Parties promptly as statements
therefor are received; PROVIDED, however, that Parent shall be obligated
pursuant to this paragraph (b) to pay for only one firm of counsel for all
Indemnified Parties in any jurisdiction unless the use of one counsel for such
Indemnified Parties would present such counsel with a conflict of interest, (ii)
the Indemnified Parties will cooperate in the defense of any such matter and
(iii) Parent shall not be liable for any settlement effected without its prior
written consent; and PROVIDED, FURTHER, that Parent shall not have any
obligation hereunder to any Indemnified Party if and when a court of competent
jurisdiction shall ultimately determine, and such determination shall have
become final and non-appealable, that the indemnification of such Indemnified
Party in the manner contemplated hereby is prohibited by applicable law. Parent
may not agree to any settlement of any such claim or action, other than solely
for monetary damages for which the Parent shall be responsible hereunder,
without the prior written consent of the Indemnified Party, which consent shall
not be unreasonably withheld. In any action hereunder as to which the Parent has
assumed the defense thereof, the Indemnified Party shall continue to be entitled
to participate in the defense thereof, with counsel of its own choice, but the
Parent shall not be obligated hereunder to reimburse the indemnified party of
the costs thereof, except as provided in the immediately preceding sentence.

     (c) Parent shall for a period of six years from the Effective Time maintain
in effect the Company's current directors' and officers' liability insurance
covering all persons who are directors and officers of the Company on the date
of this Agreement to the extent such policy provides coverage for events
occurring prior to the Effective Time; PROVIDED, HOWEVER, that (i) in no event
shall Parent be required to expend in any one year an amount in excess of 150%
of the last annual premium paid by the Company prior to the date of this
Agreement for such insurance and (ii) Parent may substitute for such Company
policy, a policy or policies with at least the same coverage containing terms
and conditions which are no less advantageous to the persons who are directors
and officers of the Company on the date of this Agreement provided that said
substitution does not result in any gaps or lapses in coverage with respect to
matters occurring prior to the Effective Time.


                                       31
<PAGE>

     6.14. TAKEOVER STATUTE. If any Takeover Statute is or may become applicable
to the Arrangement or the other transactions contemplated by this Agreement,
each of Parent and the Company and its board of directors shall grant such
approvals and take such actions as are necessary so that such transactions may
be consummated as promptly as practicable on the terms contemplated by this
Agreement, or by the Arrangement and otherwise act to eliminate or minimize the
effects of such statute or regulation on such transactions.

     6.15. PARENT CAPITAL REORGANIZATION. Prior to the Effective Date, Parent
will use its best efforts to have its shareholders approve, either at a meeting,
or by consent in writing, a reorganization of its authorized and issued capital
stock in the following manner: (i) the issued and unissued Class A Non-Voting
Shares will be changed to Parent Class A Stock with 50 votes per share; (ii) the
issued Class B Subordinate Voting Shares will be converted or exchanged into
Parent Class A Stock and the unissued Class B Subordinate Voting Shares will be
cancelled; (iii) the issued Series A Non-Voting Preferred Shares will be
converted or exchanged into Parent Class A Stock and the unissued Series A
Non-Voting Preferred Shares will be cancelled; (iv) the Class C Redeemable
Preferred Shares will be cancelled; (v) each issued Class C Multiple Voting
Share will be exchanged for 500 Class B Subordinate Voting Shares and one Class
C Non-Voting Participating Share (together, a "UNIT"), and the unissued Class C
Multiple Voting Shares will be cancelled; (vi) a class of unlimited Class D
Multiple Voting Shares will be created; (vii) a class of unlimited Class E
Non-Voting Shares will be created; and (viii) a class of unlimited Preferred
Shares issuable in series will be created (collectively, the "CAPITAL
REORGANIZATION"); PROVIDED, HOWEVER, that (i) the ratio of the voting power of
each Parent Class D Multiple Voting Share to the voting power of each share of
Parent Class A Stock shall not be greater than 10:1, (ii) the ratio of the
voting power of each Unit to the voting power of each share of Parent Class A
Stock shall not be greater than 10:1, and (iii) the ratio of the voting power of
each share of Preferred Shares (if any) established prior to the Effective Time
to the voting power of each share of Parent Class A Stock shall not be greater
than 10:1. The rights, privileges, restrictions and preferences of each class of
the New Parent Capital Stock will be in accordance with this Section 6.15 and
otherwise in all material respects as set forth in Exhibit B to this Agreement.
Notwithstanding the foregoing, Parent may change the capital structure of Parent
to provide for changes in the classes of capital stock, so long as such changes
would be economically equivalent to the Company and its Shareholders in all
material respects and any such new structure shall be deemed the "Capital
Reorganization."

     6.16. COVENANTS RELATING TO TAX FREE STATUS OF THE ARRANGEMENT. The parties
intend the Arrangement to qualify as a reorganization under Section 368(a) of
the Code. Each party will (and will cause its Subsidiaries to) both before and
after the Effective Time (i) use all reasonable efforts to cause the Arrangement
to so qualify, (ii) refrain from taking any action that would reasonably be
expected to cause the Arrangement to fail to so qualify, and (iii) take the
position for all purposes that the Arrangement so qualifies. The Company and
Parent shall each reasonably cooperate in


                                       32
<PAGE>

connection with obtaining the opinions of special counsel described in Section
7.3(c) including, without limitation, providing to special counsel such
representations that are reasonably required by special counsel to enable it to
render such opinion.

     6.17. PFIC AND GRA COVENANTS. (a) Following the Effective Time, (i) Parent
will make a good faith determination whether it constitutes a "passive foreign
investment company" for U.S. federal income tax purposes (a "PFIC") for each
taxable year ending after the Effective Time and (ii) if Parent so determines
that it does constitute a PFIC for any taxable year ending after the Effective
Time, Parent shall (1) make a good faith determination as to which of its direct
or indirect Subsidiaries constitutes a PFIC for each taxable year for which
Parent has determined in good faith that it is a PFIC and for each subsequent
taxable year, (2) provide notice of such status as a PFIC of the Parent and any
such Subsidiary to each Person that (A) held any shares of Parent Class A Stock
during the taxable year for which such status has been determined and (B)
acquired any shares of Parent Class A Stock pursuant to the Arrangement, (3) in
good faith provide each such Person with the information necessary in order for
such Person to timely (including any applicable extensions) (A) make an election
under Section 1295 of the Code for Parent and each such Subsidiary and (B)
comply with the reporting requirements applicable under Section 1295 of the Code
and (4) in good faith take any other action reasonably necessary to be taken by
Parent and reasonably requested by such Person in order for any such election to
be effective.

     (b) Following the Effective Time, in the event that any Person who
(directly or indirectly) acquires any shares of Parent Class A Stock in the
Arrangement files (or notifies Parent that it intends to file) a Again
recognition agreement@ under Section 367 of the Code and the Treasury
Regulations issued thereunder with respect to the Arrangement, the Parent shall
cooperate in good faith in connection with the filing of such agreement and any
subsequent filings required by such agreement.

     (c) In any case where specific performance is not possible, any damages
incurred as a result of a breach of this Section 6.17 will be paid solely in
shares of Parent Class A Stock at their then current fair market value unless it
has been finally determined at the time when such damages are paid that for any
reason the Arrangement does not qualify as a reorganization within the meaning
of Section 368(a) of the Code. Any such shares will be subject to all the terms
and conditions of the Voting Agreement.

     6.18. SYSTEM EXPANSION REQUIREMENTS. (a) Exhibit G to this Agreement sets
forth a schedule of the Company's and its subsidiaries' near-term estimated
backhaul capacity requirements for the period covered thereby, including the
estimated date, cost, route and proposed provider of such backhaul (the
"BACKHAUL REQUIREMENTS"). The Parties agree that the implementation of any of
the following will not constitute a breach of any other provision of this
Agreement:

     (b) NORTH AMERICA. Parent and the Company agree to enter into an agreement
as soon as practicable but not later than April 1, 2000. Such agreement will


                                       33

Worldwide Fiber Inc.
800 Fifth Avenue
Suite 4100
Seattle, WA  98104

Ladies and Gentlemen:

                  The undersigned is a holder of Common Shares, par value
$1.50 per share ("Company Common Stock"), of GlobeNet Communications Group
Limited, a Bermuda company (the "Company") and/or shares of Class B
Restricted Voting Shares, par value $1.50 per share, of the Company ("Class B
Shares"). Pursuant to the terms of that certain Agreement and Plan of Merger,
dated as of March __, 2000, by and between the Company and Worldwide Fiber
Inc., a Canadian corporation ("WFI"), Company Common Stock will be exchanged
for shares of WFI (the "Arrangement"). In connection with the Arrangement,
the undersigned, as a holder of Company Common Stock will be entitled to
receive Class A Voting Shares of WFI (the "Securities") in exchange for the
shares of Company Common Stock held by the undersigned at the effective time
of the Arrangement.

                  The undersigned acknowledges that the undersigned may be
deemed an "affiliate" of the Company within the meaning of Rule 145 ("Rule 145")
promulgated under the Securities Act of 1933, as amended (the "Act"), and/or as
such term is used in and for purposes of Accounting Series Release Nos. 130 and
135, as amended, of the Securities and Exchange Commission (the "Commission") by
virtue of the undersigned's position as an officer or director of the Company or
ownership of Company Common Stock or Class B Shares, although nothing contained
herein shall be construed as an admission of such status.

                  If in fact the undersigned were an affiliate of the Company
under the Act, the undersigned's ability to sell, assign or transfer any
Securities received by the undersigned in exchange for any shares of Company
Common Stock pursuant to the Arrangement may be restricted unless such sale,
assignment or transfer is registered under the Act or an exemption from such
registration is available. The undersigned understands that such exemptions are
limited and the undersigned has obtained advice of counsel as to the nature and
conditions of such exemptions, including information with respect to the
applicability to the sale of such Securities of Rules 144 and 145(d) promulgated
under the Act.


                                      A-1

<PAGE>

                  The undersigned hereby represents to and covenants with WFI
that it will not sell, assign or transfer any Securities received by the
undersigned in exchange for shares of Company Common Stock pursuant to the
Arrangement except (i) pursuant to an effective registration statement under the
Act, (ii) by a sale made in conformity with the volume and other limitations of
Rule 145 (and otherwise in accordance with Rule 144 under the Act, if the
undersigned is an affiliate of WFI and if so required at the time) or (iii) in a
transaction which, in the opinion of independent counsel reasonably satisfactory
to WFI, or as described in a "no-action" or interpretive letter from the Staff
of the Commission reasonably satisfactory to WFI, is not required to be
registered under the Act.

                  The undersigned understands that WFI is under no obligation to
register the sale, assignment, transfer or other disposition of the Securities
by the undersigned or on behalf of the undersigned under the Act or to take any
other action necessary in order to make compliance with an exemption from such
registration available solely as a result of the Arrangement.

                  In the event of a sale of Securities pursuant to Rule 145, the
undersigned will supply WFI with evidence of compliance with such Rule, in the
form of customary seller's and broker's Rule 145 representation letters or as
WFI may otherwise reasonably request. The undersigned understands that WFI may
instruct its transfer agent to withhold the transfer of any Securities disposed
of by the undersigned in a manner inconsistent with this letter.

                  The undersigned acknowledges and agrees that appropriate
legends will be placed on certificates representing Securities received by the

                                    AGREEMENT

                                  WITNESSETH :

                  WHEREAS, the parties entered into a Shareholders' Agreement,
dated December 31, 1998, a copy of which is attached hereto as EXHIBIT A (the
"Shareholders' Agreement");

                  WHEREAS, Mi-Tech is the holder of 50 shares of Class A Voting
Preferred Stock and 50 shares of Non-Voting Common Stock of the Company
(collectively referred to herein as the "Company Shares");

                  WHEREAS, among other things, the Shareholders' Agreement
provides Mi-Tech with an option to convert its Company Shares into shares of 360
in the event 360 effects an underwritten initial public offering of its stock
(the "IPO");

                  WHEREAS, Articles IV, V and VI of the Shareholders' Agreement
set forth the manner in which the Company Shares are to be converted into shares
of 360 of the same class and series to be offered to the public;

                  WHEREAS, 360 and Mi-Tech wish to forego the procedures set
forth in Articles IV, V and VI of the Shareholders' Agreement and instead set
forth herein the agreement of 360 and Mi-Tech with respect to the amount of 360
shares Mi-Tech will receive in exchange for the Company Shares;

                  WHEREAS, Mi-Tech has agreed to exchange the Company Shares for
fully paid and non-assessable Class A Subordinate Voting Shares (the "Class A
Subordinate Voting Shares") of 360 pursuant to this Agreement; and

                  WHEREAS, 360, Mi-Tech and the other parties to this Agreement
also wish to set forth herein other agreements which relate to 360, Mi-Tech, the
Company, the other parties to this Agreement and the Shareholders' Agreement.

<PAGE>

                  NOW, THEREFORE, for good and valuable consideration, the
receipt of which is hereby acknowledged, the parties hereby agree as follows:

                  Section 1. CONVERSION OF COMPANY SHARES INTO 360 SHARES.
Subject to the terms and conditions set forth in this Agreement, at the Closing
(as hereinafter defined), all Company Shares held by Mi-Tech shall be
transferred to 360 and 360 shall, in the manner provided below, issue in
exchange therefor, the number of shares of Class A Subordinate Voting Shares
equal to the quotient obtained by dividing Three Hundred and Twelve Million
Dollars (US$312,000,000) by the initial public offering price to the public per
share of the Class A Subordinate Voting Shares as reflected in the final
prospectus distributed in connection with the IPO (the "IPO Price"). Such
transaction is hereinafter referred to as the "Exchange". Mi-Tech hereby assigns
to William Blair & Company ("Blair") 2% of the subscription rights held by
Mi-Tech in connection with the Exchange, so that Blair shall receive 2% of the
Class A Subordinate Voting Shares to be issued in the Exchange.

                  Section 2. CLOSING; EXCHANGE OF SHARES; VALIDITY OF WORLDWIDE
SHARES.

                  (a) CLOSING. Subject to the terms and conditions set forth in
this Agreement, the closing of the Exchange (the "Closing") shall take place at
such location as 360 shall specify by notice in writing to Mi-Tech, on the day
of and immediately prior to the IPO, or on such other Business Day as may be
agreed to in writing by Mi-Tech and 360 (the "Closing Date"). For purposes of
this Agreement, "Business Day" means any day other than a Saturday, a Sunday or
a day when commercial banks in Vancouver, British Columbia are required to be
closed.

                  (b) EXCHANGE. At the Closing, Mi-Tech shall cause to be
delivered to Worldwide certificates representing Mi-Tech's Company Shares
together with such documents and instruments of transfer necessary or required
to transfer the Company Shares on the books of the Company into the name of 360,
and, within three (3) Business Days after the Closing, 360 shall deliver (i) to
Mi-Tech a certificate or certificates representing ninety-eight percent (98%) of
the Class A Subordinate Voting Shares to be issued in the Exchange; and (ii) to
Blair a certificate or certificates representing two percent (2%) of the Class A
Subordinate Voting Shares issuable in the Exchange. Each certificate
representing 360 Shares issued to Mi-Tech and to Blair shall have a legend
containing the following:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN QUALIFIED
         FOR PUBLIC DISTRIBUTION IN CANADA AND HAVE NOT BEEN REGISTERED UNDER
         THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED. THE SECURITIES
         HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD, TRANSFERRED OR
         OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH APPLICABLE CANADIAN
         SECURITIES LAWS AND THE UNITED STATES SECURITIES ACT OF 1933, AS
         AMENDED.

         IN ADDITION, THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
         TO THE RESTRICTIONS ON TRANSFER SET FORTH IN THE WORLDWIDE FIBER, INC.
         SHAREHOLDERS AGREEMENT, DATED



                                      -2-
<PAGE>

         AS OF SEPTEMBER 9, 1999, AS AMENDED, BY THE CORPORATION AND THE PARTIES
         THERETO, A COPY OF WHICH IS ON FILE IN THE OFFICE OF THE CORPORATION.

The requirement that the above securities legend be placed upon certificates
evidencing any such securities shall cease and terminate upon the earliest of
the following events: (a) when such securities are transferred in a registered
offering subsequent to the IPO; (b) when such securities are transferred
pursuant to Rule 144 under the 1933 Act; or (c) when such securities are
transferred in any other transaction if the seller delivers to 360 an opinion of
its counsel, which counsel and opinion shall be reasonably satisfactory to 360,
to the effect that such legend is no longer necessary in order to protect 360
against a violation by it of applicable securities laws upon any sale or other
disposition of such securities without registration thereunder. The requirement
that the above legend regarding the Shareholders Agreement of 360, dated
September 9, 1999, as amended (the "360 Shareholders Agreement") be placed upon
certificates evidencing any such securities shall cease and terminate upon the
termination of the 360 Shareholders Agreement. Upon the occurrence of any event
requiring the removal of a legend hereunder, 360, upon the surrender of
certificates containing such legend, shall, at its own expense, deliver
immediately to the holder of any such securities as to which the requirement for
such legend shall have terminated, one or more new certificates evidencing such
securities not bearing such legend.

                  (c) CLOSING ESCROW AGREEMENT. As soon as practicable after the
execution of this Agreement 360, Mi-Tech and Michels shall execute and deliver a
Closing Escrow Agreement (the "Closing Escrow Agreement") in the form attached
as EXHIBIT B, and each of 360, Mi-Tech and Michels shall deliver to the escrow
agent named in the Closing Escrow Agreement (the "Closing Escrow Agent") the
closing documents described in the Closing Escrow Agreement as being delivered
by such party.

                  (d) VALIDITY OF SHARES. The Class A Subordinate Voting Shares
to be issued in the Exchange shall be duly authorized by all necessary corporate
action by 360 and, upon issuance in accordance with the provisions of Sections 1
and 2 of this Agreement, such Class A Subordinate Voting Shares to be issued in
the Exchange shall be validly issued, fully paid and nonassessable.

                  (e) NO FRACTIONAL SHARES. Notwithstanding any other provision
in this Agreement, no certificates or scrip for fractional shares of Class A
Non-Voting stock shall be issued in the Exchange. In lieu of any such fractional
shares, Mi-Tech or Blair, as the case may be, shall be entitled to receive a
cash payment equal to such fraction multiplied by the IPO Price.

                  Section 3. REGISTRATION RIGHTS. The parties acknowledge that
the Registration Rights Agreement attached hereto as EXHIBIT C (the
"Registration Rights Agreement") shall be executed and delivered by 360 and
Mi-Tech pursuant to the Closing Escrow Agreement and that such Registration
Rights Agreement shall be effective concurrent with the Closing.

                                    If and to the extent the Clause B Offer is
                                    not accepted, the applicable member of the
                                    Michel's Group may sell, transfer, or
                                    otherwise dispose of such assets, as
                                    described in the Clause B Offer, to any
                                    other person, firm or corporation, but only

                                    WFI and, if such member of the Michel's
                                    Group does not do so, the provisions of this
                                    Clause (B) will again become applicable to
                                    the sale, transfer or other disposition of
                                    such assets, and so on from time to time.

                           C.       If, during the six month period referred to
                                    in Clause (B), the applicable member of the

                                    the price and terms specified in the last
                                    Offer by such member of the Michel's Group
                                    to WFI under Clause (B), then such member of
                                    the Michel's Group shall deliver to WFI a
                                    notice in writing (the "Clause C Offer")

                                    such member of the Michel's Group proposes
                                    to enter into with such third party (the
                                    "Third Party Agreement"). The Clause C Offer
                                    shall be an offer to sell to WFI all or part
                                    of such assets that are the subject matter
                                    of the Third Party Agreement on the terms
                                    and conditions referred to in the Third
                                    Party Agreement. Michel's and Mi-Tech shall
                                    forthwith provide to WFI such additional
                                    information on such assets as WFI may
                                    reasonably request. The Offer shall be open
                                    for acceptance by WFI for a period of 10
                                    Business Days (as defined in Clause (D))
                                    after its receipt by WFI. WFI may accept the
                                    offer as to all or any contiguous part of
                                    such assets. If and to the extent that the
                                    Clause C Offer is not accepted, the
                                    applicable member of the Michel's Group may
                                    transfer such assets, as described in the
                                    Clause C Offer, to the Third Party at the
                                    price and terms specified in the Third Party
                                    Agreement and, if the applicable member of
                                    the Michel's Group does not do so, the
                                    provisions of Clause (B) and this Clause (C)
                                    will again become applicable to the sale,
                                    transfer or other disposition of such
                                    assets, and so on from time to time.

                           D.       The closing of any purchase and sale of
                                    assets to be effected as a result of the

                                    Offer by WFI shall take place at the offices
                                    of WFI at a date and time that is mutually
                                    acceptable to the applicable member of the
                                    Michel's Group, or, if no date and time for
                                    closing are so agreed upon, the time for
                                    closing shall be 11:00 a.m. (Vancouver, B.C.

                                    acceptance of the Offer by WFI. For the
                                    purposes of this Clause (C) and Clause (D),
                                    "Business Day" means any day other than a
                                    Saturday and Sunday or a day when commercial

                                    closing, the applicable member of the
                                    Michels Group shall deliver or cause to be
                                    delivered to WFI or its nominee such
                                    transfer documents as WFI may reasonably

                                    members of the Michels Group shall execute
                                    and deliver any further instruments or
                                    documents and take all such further actions
                                    as WFI may reasonably request in order to
                                    evidence or effect such transfer, against
                                    delivery by WFI or its nominee of payment of
                                    the purchase price for such assets.

                           E.       Except with respect to any Clause B Offer or
                                    Clause C Offers that have been made prior to
                                    December 31, 2002 (or that were required to

                                    of this Agreement prior to such date), the
                                    obligations of Mi-Tech and Michels under
                                    this Section 1.6 shall expire on December
                                    31, 2002.

                  (b) Notwithstanding the foregoing, the Parties acknowledge and
         agree that Worldwide and Michels are leading construction contractors
         with special expertise in telecommunications construction (the "Core
         Business"). The Parties expressly agree that no provision of this
         Agreement or any other agreement between them shall be interpreted as
         to restrain or in any manner impede Michels or any member of the
         Michel's Group, Ledcor or Worldwide from performing such Core Business,
         for consideration consisting of cash or cash equivalents, except that
         until December 31, 2002, Michels and Mi-Tech shall, and shall cause the
         other members of the Michels Group to, use their good faith reasonable
         efforts not to perform telecommunications construction on the same
         right of way as a competing contractor on contracts in excess of 50
         miles within 50 miles of any point along a contiguous 50-mile segment
         of an Active Company Project. For purposes of this Section 1.6(b), an
         "Active Company Project" shall mean any project being undertaken by the
         Company with respect to which the Company has secured the legal right
         to commence construction on a contiguous 50 or more miles segment of
         the route (including attempting to own or license the applicable right
         of way and to obtain all building and construction permits and
         franchises for such segment), has commenced construction with respect
         to such contiguous 50 or more miles segment, and has executed at least
         one contract with a purchaser of strands."

                  3.4 ADDITIONAL FIBER OPTIONS.

                  (a) Mi-Tech provided, and the original execution of this
Agreement constituted, an option to the Company to purchase from Mi-Tech and its
Affiliates 24 strands of the existing Montreal to Albany fiber optic build owned
by Mi-Tech and its Affiliates, at a price and on terms no less favorable than
the price paid by any third party for the purchase of an equivalent number of
strands of the Montreal to Albany build. Such option was to be exercisable
commencing on the date such strands were available and was to terminate one year
thereafter; provided, that if no third party had purchased an equivalent number
of strands of the Montreal to Albany build prior to exercise of the option, the
exercise price and terms upon which the option was to be exercisable was to be
as mutually agreed by Mi-Tech and the Company.

Mi-Tech and the Company shall negotiate reasonably and in good faith to conclude
a definitive agreement for such purchase.

                  (g) 360 acknowledges and agrees that the foregoing
         representations, warranties and covenants set out herein are made by
         360 with the intent that they be relied upon by Mi-Tech in determining

         that the foregoing representations and warranties are true as at the
         Closing Date with the same force and effect as if they had been made by

         any change in any representation, warranty or other information
         relating to 360 set forth herein that takes place prior to the Closing
         Date.

                 Section 10. REPRESENTATIONS AND WARRANTIES OF MICHELS AND
MI-TECH. Michels and Mi-Tech represent, warrant and acknowledge to 360 as of the
date hereof and, unless otherwise provided, as of the Closing Date, as follows:

                  (a) Mi-Tech is acquiring Class A Subordinate Voting Shares as
         principal with an aggregate acquisition cost to Mi-Tech of not less
         than C$150,000 and is purchasing the Class A Subordinate Voting Shares
         for investment only and not with a view to resale or distribution in
         violation of applicable securities laws.

                  (b) Mi-Tech, if a "U.S. Person" (as defined in Regulation S

         Act"), is an "Accredited Investor" (as defined in Rule 501 under the
         1933 Act). Mi-Tech is acquiring the Class A Subordinate Voting Shares
         for its own account, for investment purposes only and not with a view
         to any resale, distribution or other disposition of the Class A
         Subordinate Voting Shares in violation of the United States securities
         laws. If Mi-Tech decides to offer, sell or otherwise transfer any of
         the Class A Subordinate Voting Shares, it will not



                                      -11-
<PAGE>

         offer, sell or otherwise transfer any of such Class A Subordinate
         Voting Shares directly or indirectly, unless such sale is made in
         compliance with, or in reliance of an exemption from, the 1933 Act and
         applicable state securities laws. Mi-Tech understands and agrees that
         there may be material tax consequences to Mi-Tech of an acquisition or
         disposition of the Class A Subordinate Voting Shares and that, except
         as expressly set forth in this Agreement, 360 gives no opinion and
         makes no representation with respect to the tax consequences to
         Mi-Tech under United States, state, local or foreign tax law of
         Mi-Tech's acquisition or disposition of such securities.

                  (c) Mi-Tech acknowledges that no offering memorandum,
         prospectus or registration statement has been prepared or filed by 360
         with any securities commission or similar authority in any jurisdiction
         in connection with the Exchange and the issue and sale of Class A
         Subordinate Voting Shares to Mi-Tech is subject to such sale being
         exempt from the requirements of applicable securities laws as to the
         filing of an offering memorandum, prospectus or registration statement.

                  (d) Mi-Tech has received and reviewed 360's Registration
         Statement on Form F-1 as filed with the Securities and Exchange
         Commission of the United States on January 28, 2000 and has had the
         opportunity to discuss the disclosure therein, as well as developments,
         concerning 360 and the industry in which it competes, with
         representatives of 360 and has received complete answers to all of its
         questions. Mi-Tech is not relying on any written or oral
         representations made by 360, except to the extent expressly provided in
         this Agreement.

                  (e) To Mi-Tech's knowledge, the Class A Subordinate Voting
         Shares were not advertised in printed media of general and regular paid
         circulation, radio or television and Mi-Tech has not purchased the
         Class A Subordinate Voting Shares as a result of any form of general
         solicitation or general advertising, including advertisements,
         articles, notices or other communications published in any newspaper,
         magazine or similar media or broadcast over radio, or television, or
         any seminar or meeting whose attendees have been invited by general
         solicitation or general advertising.

                  (f) Mi-Tech has such knowledge and experience in financial and
         business affairs as to be capable of evaluating the merits and risks of
         the investment hereunder and is able to bear the economic risk of loss
         of such investment.

                  (g) Mi-Tech understands that the Class A Subordinate Voting
         Shares have not been and will not be registered under the 1933 Act, as
         amended, or the securities laws of any state of the United States and
         that the sale contemplated hereby is being made in reliance on an
         exemption from such registration requirements and Mi-Tech understands
         and agrees that the Class A Subordinate Voting Shares may not be traded
         in the United States or by or on behalf of a U.S. Person or a person in
         the United States unless permitted by the terms of the 360 Shareholders
         Agreement and either registered under the 1933 Act and any applicable
         state securities laws or an exemption from such registration
         requirements is available and that certificates representing the Class
         A Subordinate Voting Shares will bear a legend to such effect.

                  (h) Mi-Tech understands that no prospectus has been or will be
         filed in accordance with the securities laws, and the regulations
         thereunder, of, and the applicable published rules, policy statements,
         blanket orders and notices of the securities regulatory authorities in
         the provinces and territories of Canada (the "Canadian Securities
         Laws") qualifying the distribution of the Class A Subordinate Voting
         Shares in any province or territory of Canada and that the Class A
         Subordinate Voting Shares may not be offered or sold by Mi-Tech in any
         province or territory of Canada except pursuant to an applicable
         exemption from the prospectus requirements of the applicable Canadian
         Securities Laws and from a dealer appropriately registered under the
         applicable Canadian Securities Laws or, other than in Ontario, in
         accordance with an exemption from the registration requirements of such
         laws.

                  (i) Neither Mi-Tech nor Michels has employed any broker or
         finder in connection with the transactions contemplated by this
         agreement.

                  (j) The execution, delivery and performance by Mi-Tech and
         Michels of this Agreement, and the execution, delivery and performance
         by Mi-Tech of the 360 Transaction Documents and the Agreement to be
         Bound by the 360 Shareholders Agreement (collectively the "Mi-Tech
         Transaction Documents") and the consummation by Mi-Tech and Michels of
         the transactions contemplated hereby and thereby will not (i) violate
         any provision of law, statute, rule or regulation, or any ruling, writ,
         injunction, order, judgment or decree of any court, administrative
         agency or other governmental body applicable to it, or any of its
         properties or assets; (ii) conflict with or result in any breach of any
         of the terms, conditions or provisions of, or constitute (with due
         notice or lapse of time, or both) a default (or give rise to any right
         of termination, cancellation or acceleration) under any contract to
         which Mi-Tech or Michels is a party that would materially adversely
         affect their ability to consummate the transactions contemplated by
         this agreement or perform their obligations under any Mi-Tech
         Transaction Documents; or (iii) violate its constating documents.

                  (k) Mi-Tech is duly organized and validly existing under the
         laws of the jurisdiction of its organization, and Michels is duly
         incorporated and validly existing under the laws of its jurisdiction of
         incorporation, and each has all partnership, corporate or company

         thereunder. Each of the Mi-Tech Transaction Documents has been duly
         authorized by all necessary action on the part of Mi-Tech and Michels.
         Each of the Mi-Tech Transaction Documents constitutes a valid and
         binding agreement of Mi-Tech, and this Agreement constitutes a valid
         and binding agreement of Michels, enforceable against Mi-Tech and
         Michels, as the case may be, in accordance with its terms except to the
         extent that enforceability may be limited by bankruptcy, insolvency or
         other similar laws affecting creditors' rights generally and by
         equitable principles generally whether enforced in a court of law or at
         equity.

                  (l) No permit, authorization, consent or approval of or by, or
         any notification of or filing with, any Person is required in
         connection with the execution, delivery and



                                      -13-

         performance by Mi-Tech or Michels of any Mi-Tech Transaction Document,
         the consummation by Mi-Tech or Michels of the transactions
         contemplated hereby or thereby, or the issuance, purchase or delivery
         of the Mi-Tech Shares (other than such notifications or filings
         required under applicable securities laws, if any, which shall be made
         on a timely basis and other than provided for in any Mi-Tech
         Transaction Document).

                  (m) In respect of the Company Shares (i) no Person, other than
         360 or WFN, has any written or oral agreement or option or any right or
         privilege (whether by law, pre-emptive or contractual) capable of
         becoming an agreement or option for the purchase or acquisition from
         Mi-Tech of any of the Company Shares, (ii) no Person other than 360 or
         WFN has any agreement or option or any right or privilege (whether by
         law, pre-emptive or contractual) capable of becoming an agreement,
         including convertible securities, warrants or convertible obligations
         of any nature, for the purchase, subscription, allotment or issuance of
         any unissued shares or other securities of the Company, (iii) Mi-Tech
         is the registered and beneficial owner of the Company Shares, with good
         and marketable title thereto, free and clear of any mortgage, lien,
         security interest, pledge, escrow, charge, or other encumbrance of any
         kind or character whatsoever (an "Encumbrance") and, without limiting
         the generality of the foregoing, none of the Company Shares are subject
         to any voting trust, shareholder agreement or voting agreement other
         than the Shareholders Agreement, and (d) upon completion of the
         transaction contemplated by this agreement, all of the Company Shares
         will be owned by 360 as the registered and beneficial owner, with a
         good and marketable title thereto free and clear of any Encumbrance
         except for such Encumbrances as may have been granted by 360.

                  (n) Mi-Tech and Michels acknowledge and agree that the
         foregoing representations, warranties and covenants set out herein are
         made by Mi-Tech and Michels with the intent that they be relied upon in
         determining the suitability of Mi-Tech as a purchaser of Class A
         Subordinate Voting Shares. Mi-Tech and Michels further agree that by
         Mi-Tech accepting the Class A Subordinate Voting Shares, Mi-Tech and
         Michels shall be representing and warranting that the foregoing
         representations and warranties are true as at the Closing Date with the
         same force and effect as if they had been made by Mi-Tech and Michels
         at the Closing Date and shall continue in full force and effect
         notwithstanding any subsequent disposition by Mi-Tech of the Class A
         Subordinate Voting Shares. Mi-Tech and Michels undertake to notify 360
         in writing of any change in any representation, warranty or other
         information relating to Mi-Tech or Michels set forth herein that takes
         place prior to the Closing Date.

                  (a) [Deleted]

                  (b) At any time following one (1) year after the effective
date of the first registration statement filed by the Company under the
Securities Act covering an underwritten offering of its securities to the
general public, the Holder or Holders holding, in the aggregate, at



                                      -2-
<PAGE>

least fifty percent (50%) of the then outstanding Registrable Stock, may by
notice in writing to the Company request that the Company file a Registration
Statement with respect to all or any portion of shares of Registrable Stock the
aggregate proceeds of which (after deduction for underwriter's discounts and
expenses related to the issuance) are reasonably expected to exceed $5,000,000.
Notwithstanding anything to the contrary contained herein, if the Company shall
furnish to Holder a certificate signed by the President of the Company stating
that in good faith judgment of the Board it would be seriously detrimental to
the Company or its shareholders for a registration statement to be filed in the
near future due to pending Company events, or that it would require disclosure
of material non-public information relating to the Company which, in the
reasonable opinion of the Board, should not be disclosed, then the Company's
obligation to use all reasonable efforts to register, qualify or comply under
this Section 2 shall be deferred for a period not to exceed one hundred eighty
(180) days from the date of receipt of written request from such Holders;
PROVIDED, HOWEVER, that the Company may not utilize this right more than once in
any twelve (12) month period.

                  (c) Following receipt of any notice given under this Section 2
by Holders of Registrable Stock, the Company shall immediately notify all
Holders from whom notice has not been received that such registration is to be
effected and shall use its best efforts to register under the Securities Act the
number of shares of Registrable Stock specified in such notice (and in all
notices received by the Company from other holders within twenty (20) days after
the giving of such notice by the Company to such other Holders). The Holders of
a majority of the shares of Registrable Stock to be sold in such offering may
designate the managing underwriter of such offering (subject to the consent of
the Company, which consent will not be unreasonably withheld). The Company shall
be obligated to register Registrable Stock pursuant to Section 2(b) on two (2)
occasions only, PROVIDED, HOWEVER, that such obligation shall be deemed
satisfied only when a Registration Statement covering all shares of Registrable
Stock specified in notices received as aforesaid and which have not been
withdrawn by the Holders thereof shall have become effective. A registration
which does not become effective after the Company has filed a Registration
Statement with respect thereto solely by reason of the refusal of the requesting
Holders to proceed shall be deemed to have been effected by the Company at the
request of such requesting Holders unless such requesting Holders shall have
elected to pay all the Company's reasonable expenses in connection with such
registration.

                  (d) The Holders requesting registration under this Section 2
must distribute the Registrable Stock covered by their request by means of a
public offering underwritten by a reputable national or regional underwriter.
The rights of any Holder to include its Registrable Stock in such registration
under this Section 2 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Stock in the
underwriting to the extent provided herein. All Holders proposing to distribute
their Registrable Stock through such underwriting shall (together with the
Company as provided in Section 4(b)) enter into an underwriting agreement in
customary form with the managing underwriter designated for such underwriting.

                  (e) If in the good faith judgment of the managing underwriter
of such public offering the inclusion of all of the Registrable Stock requested
for inclusion pursuant to this Section 2 would interfere with the successful
marketing of a smaller number of shares to be



                                      -3-
<PAGE>

offered, then the number of shares of Registrable Stock to be included in the
offering shall be reduced to the required level. The Company shall be entitled
to include in any Registration Statement referred to in this Section 2 shares of
Common Stock to be sold by the Company for its own account, and pursuant to the
exercise of piggyback registration rights granted by the Company pursuant to the
Other Registration Rights Agreements, except as and to the extent that, in the
opinion of the managing underwriter, such inclusion would adversely affect the
marketing of the Registrable Stock of the Holders to be sold.

                  (f) Notwithstanding anything to the contrary contained herein,
the Company shall not be obligated to effect, or to take any action to effect,
any registration pursuant to Section 2(b) during the period starting with the
date sixty (60) days prior to the Company's good faith estimate of the date of
filing of, and ending on a date one hundred eighty (180) days after the
effective date of, a Company-initiated registration; PROVIDED, that the Company
is actively employing in good faith all reasonable efforts to cause such
registration statement to become effective.

                  3. INCIDENTAL REGISTRATION. Each time the Company shall
determine to file a Registration Statement (other than in connection with the
initial public offering of the Company) in connection with the proposed offer
and sale for money of any of its securities by it or any of its security
holders, the Company will give written notice of its determination to all
Holders. Upon the written request of a Holder given within ten (10) days after
the giving of any such notice by the Company, the Company will use its best
efforts to cause all such shares of Registrable Stock, the Holders of which have
so requested registration thereof, to be included in such Registration
Statement, all to the extent requisite to permit the sale or other disposition
by the prospective seller or sellers of the Registrable Stock to be so
registered. If the Registration Statement is to cover an underwritten
distribution, the Company shall use its best efforts to cause the Registrable
Stock requested for inclusion pursuant to this Section 3 to be included in the
underwriting on the same terms and conditions as the securities otherwise being
sold through the underwriters. If, in the good faith judgment of the managing
underwriter of such public offering, the inclusion of all of the Registrable
Stock requested for inclusion pursuant to this Section 3 and other securities
would interfere with the successful marketing of a smaller number of shares to
be offered, then the number of shares of Registrable Stock and other securities
to be included in the offering (except for shares: (a) to be issued by the
Company in an offering initiated by the Company; (b) shares to be registered
pursuant to the Private Equity Registration Rights Agreement; or (c) shares to
be registered pursuant to the exercise of a demand registration right held by
one of the Company's security holders) shall be reduced to the required level
with the participation in such offering to be PRO RATA among the holders thereof
requesting such registration, based upon the number of shares of Registrable
Stock and other securities owned by such holders.

                  4. REGISTRATION PROCEDURES. If and whenever the Company is
required by the provisions of Section 2 or 3 hereof to effect the registration
of shares of Registrable Stock under the Securities Act, the Company will, at
its expense, as expeditiously as possible:

                  (a) In accordance with the Securities Act and the rules and
         regulations of the Commission, prepare and file with the Commission a
         Registration Statement with respect to such securities and use its best
         efforts to cause such Registration Statement to become



                                      -4-
<PAGE>

         and remain effective for a period of one hundred twenty (120) days or
         until the securities covered by such Registration Statement have been
         sold, whichever first occurs, and prepare and file with the Commission
         such amendments to such Registration Statement (and use its best
         efforts to cause post-effective amendments to become and remain
         effective) and supplements to the prospectus contained therein as may
         be necessary to comply with the provisions of the Securities Act with
         respect to the disposition of all securities covered by such
         Registration Statement;

                  (b) If the offering is to be underwritten in whole or in part,
         enter into a written underwriting agreement in customary form with the
         managing underwriter of the public offering;

                  (c) Furnish to the participating Holders and to the
         underwriters such reasonable number of copies of the Registration
         Statement (including all exhibits thereto), preliminary prospectus,
         final prospectus and such other documents as such underwriters and
         participating Holders may reasonably request in order to facilitate the
         public offering of such securities;

                  (d) Use its best efforts to register or qualify the securities
         covered by such Registration Statement under such state securities or
         blue sky laws of such jurisdictions (i) as shall be reasonably
         appropriate for the distribution of the securities covered by such
         Registration Statement or (ii) as such participating Holders and
         underwriters may reasonably request within twenty (20) days following
         the original filing of such Registration Statement, except that the
         Company shall not for any purpose be required to execute a general
         consent to service of process, to subject itself to taxation, or to
         qualify to do business as a foreign corporation in any jurisdiction
         where it is not so qualified;

                  (e) Notify the Holders participating in such registration,
         promptly after it shall receive notice thereof, of the date and time
         when such Registration Statement and each post-effective amendment
         thereto has become effective or a supplement to any prospectus forming
         a part of such Registration Statement has been filed;

                  (f) Notify the Holders participating in such registration
         promptly of any request by the Commission or any state securities
         commission or agency for the amending or supplementing of such
         Registration Statement or prospectus or for additional information;

                  (g) Prepare and file with the Commission, promptly upon the
         request of any such participating Holders, any amendments or
         supplements to such Registration Statement or prospectus which is
         required under the Securities Act or the rules and regulations
         thereunder in connection with the distribution of the Registrable Stock
         by such participating Holders;

                  (h) Prepare and promptly file (in any event within twenty (20)
         days) with the Commission, and immediately notify such participating
         Holders of the need to file and of the filing of, such amendments or
         supplements to such Registration Statement or



                                      -5-
<PAGE>

         prospectus as may be necessary to correct any statements or omissions
         if, at the time when a prospectus relating to such securities is
         required to be delivered under the Securities Act, any event has
         occurred as the result of which any such prospectus or any other
         prospectus as then in effect would include an untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading;

                  (i) In case any of such participating Holders or any
         underwriter for any such Holders is required to deliver a prospectus at
         a time when the prospectus then in circulation is not in compliance
         with the Securities Act or the rules and regulations of the Commission,
         prepare promptly upon request such amendments or supplement to such
         Registration Statement and such prospectus as may be necessary in order
         for such prospectus to comply with the requirements of the Securities
         Act and such rules and regulations;

                  (j) Advise such participating Holders, promptly after it shall
         receive notice or obtain knowledge thereof, of the issuance of any stop
         order by the Commission or any state securities commission or agency
         suspending the effectiveness of such Registration Statement or the
         initiation or threatening of any proceeding for that purpose and
         promptly use its best efforts to prevent the issuance of any stop order
         or to obtain its withdrawal if such stop order should be issued;

                  (k) At the request of any participating Holder (i) furnish on
         the date that such Registrable Stock is delivered to the underwriters
         for sale in connection with such registration, an opinion, dated such
         date, of the counsel representing the Company for the purposes of such
         registration, addressed to the underwriters, in form and substance as
         it customarily provided by issuer's counsel to underwriters in an
         underwritten public offering and (ii) use its best efforts to furnish
         letters dated each such effective date and such closing date, from the
         independent certified public accountants of the Company, addressed to
         the underwriters, in form and substance as is customarily provided by
         independent certified public accountants to underwriters in an
         underwritten public offering; and

                  (l) Cooperate with the Holders to facilitate the timely
         preparation and delivery (under normal way settlement procedures) of
         certificates representing securities to be sold pursuant to any
         Registration Statement free of any restrictive legends and in such
         denominations and registered in such names as Holders may request prior
         to sales of securities pursuant to such Registration Statement.

                  5. EXPENSES. With respect to each registration effected
pursuant to Section 2 and 3 hereof, all fees, costs and expenses of and
incidental to such registration and the public offering in connection therewith
shall be borne by the Company; PROVIDED, HOWEVER, that security Holders
participating in any such registration shall bear (a) their PRO RATA share of
the underwriting discounts and selling commissions; (b) the fees and expenses of
more than one counsel for the selling Holders selected by Holders of a majority
of the Registrable Stock to be registered, which additional counsel, if any,
shall be paid by the Holder or Holders that engaged



                                      -6-
<PAGE>

such counsel; and (c) expenses in excess of $15,000 of any special audit
required in connection with a demand registration, which shall be paid by the
selling Holders in proportion to the aggregate value of the securities offered
for sale by each of them. The fees, costs and expenses of registration to be
borne by the Company as provided in this Section 5 above, shall include, without
limitation, all registration, filing fees, printing expenses, fees and
disbursements of counsel and accountants for the Company, fees and disbursements
of counsel for the underwriter or underwriters of such securities (if the
Company and/or selling security holders are otherwise required to bear such fees
and disbursements), all legal fees and disbursements and other expenses of
complying with state securities or blue sky laws of any jurisdictions in which
the securities to be offered are to be registered or qualified, reasonable fees
and disbursement of one counsel for the Holders and the premiums and other costs
of policies of insurance insuring the Company against liability arising out of
such public offering. Notwithstanding the foregoing, the Company shall not be
required to pay for any expenses of any registration proceeding begun pursuant
to Section 2 above if the registration request is subsequently withdrawn (other
than a withdrawal due to (i) a material adverse change in the Company's business
or financial condition or (ii) a reduction in the closing sale price of the
Company's Common Stock (as reported in THE WALL STREET JOURNAL) since the
registration was initiated by the Holders) at the request of the Holders of a
majority of the Registrable Stock to be registered (which Holders shall bear
such expenses), unless the Holders of a majority of the Registrable Stock agree
to forfeit the right to one demand registration pursuant to Section 2.

                  6. INDEMNIFICATION AND CONTRIBUTION.

                  (a) The Company will indemnify and hold harmless each Holder
of shares of Registrable Stock which are included in a Registration Statement
pursuant to the provisions of this Agreement, the directors, officers, employees
and agents of such Holder, any underwriter (as defined in the Securities Act) of
the securities covered by the Registration Statement, the directors, officers,
employees and agents of such underwriter, and any Person who controls such
Holder or such underwriter within the meaning of the Securities Act or the
Exchange Act, and each of their successors, from and against any and all claims,
actions, demands, losses, damages or liabilities (including legal and other
expenses reasonably incurred in connection with defending same), joint or
several (collectively, "Damages"), to which they or any of them may become
subject under the Securities Act, the Exchange Act or other federal or state
statutory law or regulation, at common law or otherwise, insofar as such Damages
arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in such Registration Statement (including all
documents incorporated therein by reference) as originally filed or in any
amendment thereto, any preliminary or final prospectus contained therein or any
amendment or supplement thereto, or arise out of or are based upon the ommission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading or arise out
of or are based on any violation or alleged violation of any federal, state or
common law rule or regulation applicable to the Company and relating to action
required of or inaction by the Company in connection with any such registration
and agrees to reimburse each such Holder, as incurred, for any legal or other
expenses reasonably incurred by it in connection with the investigation or
defending any such Damages; PROVIDED, HOWEVER, that the Company will not be
liable in any such case to the extent that any such Damages arise out of or are
based upon an untrue statement or alleged untrue statement or



                                      -7-
<PAGE>

omission or alleged omission so made in reliance upon and in strict conformity
with information furnished by such Holder, such underwriter or such controlling
Person in writing specifically for use in the preparation thereof. This
indemnity shall be in addition to any liability which the Company may otherwise
have and shall be in addition to any subsequently executed indemnity agreements.

                  (b) Each Holder of shares of the Registrable Stock which are
included in a registration pursuant to the provisions of this Agreement will,
severally, indemnify and hold harmless the Company, the directors, officers,
employees and agents of the Company, any underwriter (as defined in the
Securities Act) of the securities covered by the Registration Statement, the
directors, officers, employees and agents of such underwriter, and any Person
who controls the Company or such underwriter within the meaning of the
Securities Act or the Exchange Act, and each of their successors, from and
against any and all Damages, joint or several, to which they or any of them may
become subject under the Securities Act, the Exchange Act or other federal or
state statutory law or regulation, at common law or otherwise, insofar as such
Damages arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in such Registration Statement
(including all documents incorporated therein by reference) as originally filed
or in any amendment thereto, any preliminary or final prospectus contained
therein or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
in each case to the extent, but only to the extent that such untrue statement or
alleged untrue statement or omission or alleged omission was so made in reliance
upon and in strict conformity with written information furnished by such Holder
for use in the preparation thereof. This indemnity shall be in addition to any
liability which such Holder may otherwise have and shall be in addition to any
subsequently executed indemnity agreements.

                  (c) Promptly after receipt by a party to be indemnified
pursuant to the provision of paragraph (a) or (b) of this Section 6 (an
"indemnified party") of notice of the commencement of any action involving the
subject matter of the foregoing indemnity provisions, such indemnified party
will, if a claim thereof is to be made against the indemnifying party pursuant
to the provisions of paragraph (a) or (b), notify the indemnifying party of the
commencement thereof; but the omission so to notify the indemnifying party will
not relieve it from any liability which it may have to an indemnified party
otherwise than under this Section 6 and shall not relieve the indemnifying party
from liability under this Section 6 unless such indemnifying party is prejudice
by such omission. The indemnifying party shall be entitled to appoint counsel of
the indemnifying party's choice at the indemnifying party's expense to represent
the indemnified party in any action for which indemnification is sought (in
which case the indemnifying party shall not thereafter be responsible for the
fees and expenses of any separate counsel retained by the indemnified party or
parties except as set forth below); PROVIDED, HOWEVER, that such counsel shall
be reasonably satisfactory to the indemnified party. Notwithstanding the
indemnifying party's election to appoint counsel to represent the indemnified
party in an action, the indemnified party shall have the right to employ
separate counsel (including local counsel), and the indemnifying party shall
bear the reasonable fees, costs and expenses of such separate counsel (and local
counsel) if (i) the use of counsel chosen by the indemnifying party to represent
the indemnified party would present such counsel with a conflict



                                      -8-
<PAGE>

of interest; (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party; (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action; or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party. An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding.

                  (d) In order to provide for just and equitable contribution to
joint liability under the Securities Act in any case in which either (i) any
Holder exercising rights under this Agreement, or any controlling Person of any
such Holder, makes a claim for indemnification pursuant to this Section 6 but it
is judicially determined (by the entry of a final judgment or decree by a court
of competent jurisdiction and the expiration of time to appeal or the denial of
the last right of appeal) that such indemnification may not be enforced in such
case notwithstanding the fact that this Section 6 provides for indemnification
is such case, or (ii) contribution under the Securities Act may be required on
the part of any such selling Holder or any such controlling Person in
circumstances for which indemnification is provided under this Section 6; then,
and in each such case, the Company and such Holder will contribute to the
aggregate Damages in such proportion as is appropriate to reflect the relative
fault of the indemnifying party, on the one hand, and the indemnified party, on
the other. Relative fault shall be determined by reference to whether any
alleged untrue statement or omission relates to information provided by the
indemnifying party, on the one hand, or by the indemnified party, on the other
hand. The parties agree that it would not be just and equitable if contribution
were determined by pro rata allocation or any other method of allocation which
does not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section 6,
each Person who controls a Holder within the meaning of either the Securities
Act or the Exchange Act and each director, officer, employee and agent of such
Holder shall have the same rights to contribution as such Holder, and each
Person who controls the Company within the meaning of either the Securities Act
or the Exchange Act, each officer of the Company who shall have signed the
Registration Statement and each director of the Company shall have the same
rights to contribution as the Company, subject in each case to the applicable
terms and conditions of this paragraph (d); PROVIDED, HOWEVER, that, in any such
case, no Person or entity guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) will be entitled to contribution
from any Person or entity who was not guilty of such fraudulent
misrepresentation.


                                      -9-
<PAGE>

                  (e) Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

                  (f) The provisions of this Section 6 will remain in full force
and effect, regardless of any investigation made by or on behalf of any Holder
or the Company or any of the officers, directors, employees or agents or
controlling Persons referred to in Section 6 hereof, and will survive the sale
by a Holder of securities covered by a Registration Statement.

                  7. REPORTING REQUIREMENTS UNDER EXCHANGE ACT. When it is first
legally required to do so, the Company shall register its Common Stock under
Section 12 of the Exchange Act and shall keep effective such registration and
shall timely file such information, documents and reports as the Commission may
require or prescribe under Section 13 of the Exchange Act. From and after the
effective date of the first Registration Statement filed by the Company, the
Company shall (whether or not it shall then be required to do so) timely file
such information, documents and reports as the Commission may require or
prescribe under Section 13 or 15(d) (whichever is applicable) of the Exchange
Act. The Company acknowledges and agrees that the purposes of the requirements
contained in this Section 7 are (a) to enable any such Holder to comply with the
current public information requirement contained in Paragraph (c) of Rule 144
under the Securities Act should such Holder ever wish to dispose of any of the
securities of the Company acquired by it without registration under the
Securities Act in reliance upon Rule 144 (or any other similar or successor
exemptive provision), and (b) to qualify the Company for the use of Registration
Statements on Form S-3 or Form F-3 (or any successor form or forms). In
addition, the Company shall take such other measures and file such other
information, documents and reports, as shall hereafter be required by the
Commission as a condition to the availability of Rule 144 under the Securities
Act (or any similar or successor exemptive provision hereafter in effect) and
the use of Form S-3 or Form F-3 (or any successor form or forms). From and after
the effective date of the first Registration Statement filed by the Company, the
Company agrees to use its best efforts to facilitate and expedite transfers of
Registrable Stock pursuant to Rule 144 under the Securities Act (or any similar
or successor exemptive provision hereafter in effect), which efforts shall
include timely notice to its transfer agent to expedite such transfers of
Registrable Stock.

                  8. DELAY OF REGISTRATION. No Holder shall have any right to
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Agreement.

                  9. WAIVERS. The terms provided for in this Agreement may be
amended, waived, discharged or terminated (either generally or in a particular
instance and either retroactively or prospectively) only by a writing executed
by the Company and the Holders of a majority of the Registrable Stock, and any
such amendment, waiver, discharge or termination shall be binding on all the
Holders, but in no event shall the obligation of any Holder be materially
increased, except upon the written consent of such Holder.


                                      -10-
<PAGE>

                  10. ASSIGNMENT. The rights to cause the Company to register
securities granted to Holders by the Company pursuant hereto may not be
transferred or assigned for 180 days after the date of grant except to any
Affiliate of a Holder; PROVIDED that the Company is, within a reasonable period
of time after such transfer, furnished with written notice of the name and
address of such transferee or assignee and the securities with respect to which
such registration rights are being assigned; and PROVIDED, FURTHER, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Securities Act.

                  11. TERMINATION. The registration rights provided for in this
Agreement shall terminate as to all Holders on the fifth anniversary of the
closing of the Company's first public offering (the "Fifth Anniversary")
PROVIDED, HOWEVER, such termination shall be postponed until the later of (i)
that number of days following such Fifth Anniversary equal to the number of
days, if any, between the date of such first public offering and the Fifth
Anniversary that the Common Stock of the Company is not traded on a national
stock exchange or the Nasdaq National Market System (or any successor
organization) and (ii) if as of the Fifth Anniversary, the Company is not so
traded, then, one year following such date as the Company first resumes trading
on a national stock exchange or the Nasdaq National Market System (or any
successor organization).

                  12. THIRD PARTY BENEFICIARIES. Blair and any Affiliate of
Mi-Tech who is a Holder shall be express third party beneficiaries of this
Agreement.

                    BLAIR REPRESENTATION AND ACKNOWLEDGEMENT



TO:               360networks inc.

WHEREAS:

A.                By an Agreement made as of the 20th day of March 2000 (the
"Share Exchange Agreement") by and among 360networks inc. ("360"), Worldwide
Fiber (USA), Inc. (the "Company"), Mi-Tech Communications, LLC ("Mi-Tech"),
Michels Pipeline Construction, Inc. and the other parties named therein, Mi-Tech
agreed to exchange its shares of the Company for Class A Subordinate Voting
Shares of 360, and assigned 2% of its subscription rights in respect thereof to
William Blair & Company ("Blair").

B.                Under the Share Exchange Agreement Mi-Tech has agreed that,
prior to the issuance of shares (the "Blair Shares") by 360 to Blair, it shall
cause Blair to execute and deliver this instrument to 360.

THEREFORE, in consideration of the issuance of the Blair Shares to Blair, and
for other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, Blair covenants to and for the benefit of 360 as
follows:

                  Section 1. DEFINED TERMS. Terms having a meaning defined in
the Share Exchange Agreement shall have the same meaning when used in this
instrument, unless the context otherwise requires.

                  Section 2. REPRESENTATIONS AND WARRANTIES OF BLAIR. Blair
represents, warrants and acknowledges to 360 as of the date hereof and, unless
otherwise provided, as of the Closing Date, as follows:

                  (a) Blair is acquiring Class A Subordinate Voting Shares as
         principal with an aggregate acquisition cost to Blair of not less than

         applicable state securities laws. Blair understands and agrees that
         there may be material tax consequences to Blair of an acquisition or
         disposition of the Class A Subordinate Voting Shares and that, except
         as expressly set forth in this Agreement, 360 gives no opinion and
         makes no representation with respect to the tax consequences to Blair
         under United States, state, local or foreign tax law of Blair's
         acquisition or disposition of such securities.

                  (c) Blair acknowledges that no offering memorandum, prospectus
         or registration statement has been prepared or filed by 360 with any
         securities commission or similar authority in any jurisdiction in
         connection with the Exchange and the issue and sale of Class A
         Subordinate Voting Shares to Blair is subject to such sale being exempt
         from the requirements of applicable securities laws as to the filing of
         an offering memorandum, prospectus or registration statement.

         Statement on Form F-1 as filed with the Securities and Exchange
         Commission of the United States on January 28, 2000 and has had the
         opportunity to discuss the disclosure therein, as well as developments,
         concerning 360 and the industry in which it competes, with
         representatives of 360 and has received complete answers to all of its
         questions. Blair is not relying on any written or oral representations

         solicitation or general advertising, including advertisements,
         articles, notices or other communications published in any newspaper,
         magazine or similar media or broadcast over radio, or television, or
         any seminar or meeting whose attendees have been invited by general
         solicitation or general advertising.

                  (f) Blair has such knowledge and experience in financial and
         business affairs as to be capable of evaluating the merits and risks of
         the investment hereunder and is able to bear the economic risk of loss
         of such investment.

                  (g) Blair understands that the Class A Subordinate Voting
         Shares have not been and will not be registered under the 1933 Act, as
         amended, or the securities laws of any state of the United States and
         that the sale contemplated hereby is being made in reliance on an
         exemption from such registration requirements and Blair understands and
         agrees that the Class A Subordinate Voting Shares may not be traded in
         the United States or by or on behalf of a U.S. Person or a person in
         the United States unless permitted by the terms of the 360 Shareholders
         Agreement and either registered under the 1933 Act and any applicable
         state securities laws or an exemption from such registration
         requirements is available and that certificates representing the Class
         A Subordinate Voting Shares will bear a legend to such effect.

                  (h) Blair understands that no prospectus has been or will be
         filed in accordance with the securities laws, and the regulations
         thereunder, of, and the applicable

         the Class A Subordinate Voting Shares in any province or territory of
         Canada and that the Class A Subordinate Voting Shares may not be
         offered or sold by Blair in any province or territory of Canada except
         pursuant to an applicable exemption from the prospectus requirements

         appropriately registered under the applicable Canadian Securities Laws
         or, other than in Ontario, in accordance with an exemption from the
         registration requirements of such laws.

         with the transactions contemplated by the Share Exchange Agreement.

                  (j) Blair acknowledges and agrees that the foregoing

         notwithstanding any subsequent disposition by Blair of the Class A
         Subordinate Voting Shares. Blair undertakes to notify 360 in writing of
         any change in any representation, warranty or other information
         relating to Blair set forth herein that takes place prior to the

                                       and
                        CANADIAN NATIONAL RAILWAY COMPANY

                            SHARE EXCHANGE AGREEMENT

         THIS AGREEMENT, dated as of March 6, 2000 (as amended from time to
time, this "AGREEMENT") is entered into, by and among WORLDWIDE FIBER INC., a
Canadian corporation (the "CORPORATION"), and CANADIAN NATIONAL RAILWAY COMPANY,
a corporation continued under the laws of Canada ("CN").

                                   WITNESSETH:

WHEREAS:

A.       CN is the holder of 25 Class A common shares (the "CN WFI-CN SHARES")
in the capital stock of WFI-CN Fibre Inc., a Canadian corporation ("WFI-CN");

B.       CN has agreed to exchange the CN WFI-CN Shares and $20 million for a
total of 7,460,433 fully paid and non-assessable Class A Non-Voting Shares (the
"CLASS A NON-VOTING SHARES") in the capital stock of the Corporation, having the
terms set forth in the Articles (the "ARTICLES") of the Corporation in effect on
the date hereof, a copy of which is attached hereto as Schedule B.

         ACCORDINGLY, the parties hereto hereby agree as follows: SECTION 1-
EXCHANGE FOR CLASS A NON-VOTING SHARES

1.1      THE EXCHANGE.

         Subject to the terms and conditions set forth in this agreement, at the
Closing, CN shall transfer to the Corporation the CN WFI-CN Shares (which the
parties agree and declare have a value of $40 million) and pay to the
Corporation $20 million, and the Corporation shall issue to CN, in exchange
therefor, 7,460,433 Class A Non-Voting Shares (the "EXCHANGE"), subject to
adjustment as set forth in Section 1.4 (such Class A Non-Voting Shares or other
shares into which such Class A Non-Voting Shares have been converted, exchanged,
reclassified or recapitalized, together with all Class A Non-Voting Shares
issued or to be issued to CN and less any shares surrendered or to be
surrendered by CN to the Corporation pursuant to an adjustment made or to be
made pursuant to Section 1.4, all as the same may be subdivided, redivided,
consolidated, combined or reduced from time to time, and including any shares
issued thereon by way of a stock dividend or other distribution, are herein
called the "CN SHARES"). For greater clarity, the aggregate issue price of the
CN Shares shall be $60 million.



<PAGE>


1.2      THE CLOSING.

         Subject to the terms and conditions set forth in this agreement, the
closing of the Exchange (the "CLOSING") shall take place at the offices of
Campney & Murphy, 21st Floor, 1111 West Georgia Street, Vancouver, British
Columbia on March 6, 2000 or such other Business Day as may be agreed to in
writing by each of the parties hereto (the "CLOSING DATE"). For purposes of this
agreement, "BUSINESS DAY" means any day other than a Saturday, a Sunday or a day
when commercial banks in Vancouver, British Columbia are required to be closed.

1.3      DELIVERIES AT THE CLOSING (a) At the Closing, and each time Class A
Non-Voting Shares are issued to CN pursuant to Section 1.4, the Corporation
shall deliver to CN a certificate or certificates representing the Class A
Non-Voting Shares to be issued to CN in the Exchange or pursuant to Section 1.4,
as the case may be, registered in the name of CN, against, in the case of the
Class A Non-Voting Shares issued at the Closing, delivery at the Closing by CN
of payment of $20 million and certificates for the CN WFI-CN Shares, accompanied
by such documents and instruments of transfer necessary or required to transfer
the CN WFI-CN Shares, on the books of WFI-CN, into the name of the Corporation.

         Each certificate representing CN Shares shall bear a legend containing
the following words:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN QUALIFIED
         FOR PUBLIC DISTRIBUTION IN CANADA AND HAVE NOT BEEN REGISTERED UNDER
         THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED. THE SECURITIES
         HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD, TRANSFERRED OR
         OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH APPLICABLE CANADIAN
         SECURITIES LAWS AND THE UNITED STATES SECURITIES ACT OF 1933, AS
         AMENDED.

         IN ADDITION, THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
         TO THE RESTRICTIONS ON TRANSFER SET FORTH IN THE SHAREHOLDERS
         AGREEMENT, DATED AS OF SEPTEMBER 9, 1999, AS AMENDED, BY THE
         CORPORATION AND THE PARTIES THERETO, A COPY OF WHICH IS ON FILE IN THE
         OFFICE OF THE CORPORATION.

The requirement that the above securities legend be placed upon certificates
evidencing any such securities shall cease and terminate upon the earliest of
the following events: (a) when such securities are transferred in an initial
public offering; (b) when such securities are transferred pursuant to Rule 144
under the 1933 Act; or (c) when such securities are transferred in any other





                                      -2-
<PAGE>


transaction if the seller delivers to the Corporation an opinion of its counsel,
which counsel and opinion shall be reasonably satisfactory to the Corporation to
the effect that such legend is no longer necessary in order to protect the

1.4      ADJUSTMENTS

         (a) If at any time after the Closing and prior to the closing of the
issue of IPO Shares pursuant to the IPO, the Actual Number of Issue Event Shares
on an Adjustment Date:

             (i) is greater than 110% of the Assumed Number of Issue Event
             Shares, or

             (ii) is less than 90% of the Assumed Number of Issue Event Shares,

then the Corporation shall promptly thereafter advise CN by notice in writing of
the occurrence of such event and:

             (iii) if the Actual Number of Issue Event Shares is greater than
             110% of the Assumed Number of Issue Event Shares, then the
             Corporation will issue to CN for no additional payment by CN to the
             Corporation and as an adjustment to the number of Class A
             Non-Voting Shares to be issued to CN in the Exchange, (A) that
             number of Class A Non-Voting Shares equal to (2.040816% of that
             number which is the Actual Number of Issue Event Shares less the
             Assumed Number of Issue Event Shares) (B) less the aggregate number
             of Class A Non-Voting Shares issued pursuant to this subsection
             1.4(a)(iii) prior to such time, (C) plus the aggregate number of
             Class A Non-Voting Shares surrendered pursuant to subsection
             1.4(a)(iv) prior to such time; and

             (iv) if the Actual Number of Issue Event Shares is less than 90% of
             the Assumed Number of Issue Event Shares, then CN will surrender to
             the Corporation for cancellation and without further consideration,
             as an adjustment to the number of Class A Non-Voting Shares to be
             issued in the Exchange, (A) that number of Class A Non-Voting
             Shares equal to (2.040816% of that number which is the Assumed
             Number of Issue Event Shares less the Actual Number of Issue Event
             Shares) (B) less the aggregate number of Class A Non-Voting Shares
             surrendered pursuant to this subsection 1.4(a)(iv) prior to such
             time, (C) plus the

             aggregate number of Class A Non-Voting Shares issued pursuant to
             subsection 1.4(a)(iii).

If the Adjustment Date is on the occurrence of the IPO, then such issuance or
surrender shall be effected immediately prior to the IPO as soon as practicable
thereafter. If CN sells all of the CN Shares in a sale permitted under this
Agreement and the Other Transaction Documents, the obligations of the
Corporation and CN under this Section 1.4(a) shall terminate. If CN sells part
of the CN Shares prior to an Adjustment Date in a sale permitted under this
Agreement and the Other Transaction Documents, then the number of Shares to be
issued by the Corporation under subsection 1.4(a)(iii) or surrendered by CN
under subsection 1.4(a)(iv) shall be multiplied by a fraction, the numerator of
which is the number of CN Shares held by CN on the Adjustment Date, and the
denominator of which is the original number of CN Shares, as previously adjusted
under this subsection 1.4(a) and under subsection 1.4(e).

On the date of the IPO, or immediately prior to the IPO, the Corporation shall
give notice in writing to CN specifying the Actual Number of Issue Event Shares.

For purposes of this agreement:

"ACTUAL NUMBER OF ISSUE EVENT SHARES" means, at an Adjustment Date, the Assumed
Number of Issue Event Shares:

             (i) plus the number of any Common Shares or Common Share
             Equivalents issued by the Corporation after December 16, 1999 as
             Below Market Employee Shares, subject to adjustment as set forth in
             subsection 1.4(e); and

             (ii) in respect of the Michels Roll-up Transaction, if the actual
             number of Common Shares or Common Share Equivalents issued in
             respect of the Michels Roll-up Transaction, including Preferred
             Shares issued pursuant to the Preferred Share Purchase Agreement as
             a result of the Michels Roll-up Transaction (subject to adjustment

             ROLL-UP NUMBER") exceeds the sum of the totals of the Common Shares
             and Preferred Shares shown on Schedule 1.4 as having been assumed,

             Michels Roll-up Transaction, including pursuant to the Preferred
             Share Purchase Agreement as a result of the Michels Roll-up
             Transaction (subject to adjustment as set forth in subsection
             1.4(e), collectively the "ASSUMED MICHELS ROLL-UP NUMBER"), then
             plus the amount by which the Actual Michels Roll-up Number exceeds
             the Assumed Michels Roll-up Number or, if the Actual Michels
             Roll-up Number is less than the Assumed Michels Roll-up Number,
             then less the amount by which the Actual Michels Roll-up Number is
             less than the Assumed Michels Roll-up Number.

"ADJUSTMENT DATE" means the date of the closing of the IPO and, if the IPO has
not then occurred, June 30, 2000, September 30, 2000, December 31, 2000, and

(other than (i) Worldwide Fiber Holdings Ltd., Ledcor Limited Partnership, Larry
Olsen and Stephen Stow, to the extent of certain private sales agreed to before
the closing of the IPO, (ii) Ledcor Limited Partnership, the "selling
shareholder" identified in the registration statement filed with the U.S.
Securities and Exchange Commission on Form F-1 dated January 28, 2000, and (iii)
Ledcor Limited Partnership to the extent of transfers of shares pursuant to its
Designated Share Program) are also locked up for a period of not less than one
year from the effective date of the IPO. The Corporation shall exercise its
reasonable best efforts such that no waivers of such lockups be given by such
underwriter(s) or the Corporation prior to the end of such one-year period,
unless CN is granted a waiver for not less than a prorata portion of the number
of shares in respect of which the waiver is being granted. For the purpose of
this section "prorata" means that:

         (a) if a single such shareholder has its lockup waived so that it is
permitted to sell a percentage of its shares (the "Specified Percentage"), then
CN shall be entitled to a similar waiver of the Specified Percentage of CN's
holdings; and

         (b) if there are more than one such shareholder, then CN shall be
entitled to a similar waiver for the highest such Specified Percentage for all
such shareholders

         (calculated in each case to include the holdings of such shareholder
and of its affiliates). For purposes hereof, "affiliate" means any natural
person, partnership, corporation or other legal entity ("Person") that directly
or indirectly controls, or is under common control with, or is controlled by
another Person, where "control" means the possession, directly or indirectly, of
more than fifty percent (50%) of the combined voting power of all outstanding
securities, or the direction of management or policies (whether through
ownership of securities or partnership or other ownership interests, by contract
or otherwise).

SECTION 12 - REMEDIES.

         In case any one or more of the covenants and/or agreements set forth in
this agreement shall have been breached by any party hereto, each other party
may proceed to protect and enforce its rights either by suit in equity and/or by
action at law, including, but not limited to, an action for damages as a result
of any such breach and/or an action for specific performance of any such
covenant or agreement contained in this agreement, and to exercise all other
rights existing in their favor. The parties hereto agree and acknowledge that
money damages may not be an adequate remedy for any breach of the provisions of
this agreement and that each party may in its sole discretion apply to any court
of law or equity of competent jurisdiction for specific







                                    -21-

performance and/or injunctive relief (without posting a bond or other security)

agreement.

SECTION 13 - FURTHER ASSURANCES.

instruments or documents and to take all such further action as the other party
may reasonably request in order to evidence or effectuate the consummation of
the transactions contemplated hereby and to otherwise carry out the intent of
the parties hereunder.

                                 SCHEDULE 4.3(a)

                         SURVIVING IC SIDE LETTER TERMS

The terms in the Schedule relate to the Amended and Restated License Agreements
(each a "License Agreement" and collectively the "License Agreements") dated as
of March 6, 2000 among Worldwide Fiber Inc. ("WFI"), Illinois Central Railroad
Company ("IC"), and, respectively, IC Fiber Illinois LLC, IC Fiber Kentucky LLC,
IC Fiber Tennessee LLC, IC Fiber Mississippi LLC, IC Fiber Louisiana LLC, IC
Fiber Alabama LLC and IC Fiber Iowa LLC (each such limited liability company a
"Newco" and collectively the "Newcos").

1.       Any terms used in this Schedule as defined terms and not defined herein
         shall have the meanings assigned to them or in the License Agreements
         as the context requires.

2.       WFI and IC have entered into the License Agreements, each of which
         covers the IC ROW in one of the States of Illinois, Kentucky,
         Tennessee, Mississippi, Louisiana, Alabama and Iowa. Both WFI and IC
         believe the use of a separate License Agreement for the IC ROW located
         in each of such States is beneficial and furthers the purposes of the
         License Agreements. However, WFI has advised IC that WFI may in the
         future include the interest of the Newcos under the License Agreements
         in a public offering of securities ("Offering"), to be issued by WFI or
         an affiliate, and IC has agreed that, in the event it is reasonably
         determined by the lead underwriter for such Offering that the use of a
         separate License Agreement for each State (as opposed to one agreement
         covering the entire IC ROW in all of the States referred to above) will
         result in the Offering having a lower initial valuation than would be
         the case if one agreement were employed, IC will, within 14 days
         following written notice thereof from WFI, modify the License Agreement
         structure (other than a modification which would eliminate any of the
         Newcos) or enter into another arrangement in order to develop an
         alternative which provides WFI with an initial valuation at least equal
         to the initial valuation that would be achieved if one agreement were
         utilized for the entire IC ROW. In addition, IC has agreed that it will
         bear any incremental direct administrative costs (as reasonably
         determined by the management of WFI LLC) resulting from the current
         License Agreement structure.

3.       Should IC be required by judgement or other order of a court or other
         tribunal (notwithstanding that IC may appeal or otherwise contest such
         judgement or order) other than a judgement or order with respect to the
         existing agreements by and between CN and fONOROLA Telecommunications,
         Limited Partnership, or should IC reasonably determine that it has a
         legal obligation, to grant to a party other than the Newcos a license
         or other rights with respect to the IC ROW for the purpose of
         installing and maintaining a fiber optic communications system, IC
         hereby irrevocably appoints each Newco to negotiate the consideration
         (subject to any limitations imposed by an applicable law) for the
         license or other rights granted to such party on a per-mile basis, and
         IC will pay over to the appropriate Newco the net amount of such
         consideration when and as received by IC.

<PAGE>

4.       As soon as and to the extent practicable, the following grants of Fiber
         Optic Cable capacity shall be made to IC:

         (a)  to IC, upon request by IC, the rights, for railroad purposes, to
              Fiber Optic Cable capacity at all times equivalent to (i) two (2)
              Fiber Optic Cable strands along the entire length of the Initial
              Facility, including spur lines to major traffic centers, and (ii)
              two (2) Fiber Optic Cable strands along the entire length of each
              Additional Facility, including spur lines to major traffic
              centres.

5.       Pursuant to Section 4 and the License Agreements IC, from time to time,
         has the right to acquire Fiber Optic Cable capacity from the Newcos
         along the IC ROW. IC agrees that to the extent any of the Newcos or WFI
         LLC incur tax liability as a result of the acquisition of Fiber Optic
         Cable strands by IC, IC shall reimburse the Newcos or WFI LLC, as the
         case may be, for the amount of any tax which becomes payable (including
         all related costs, penalties and interest) by such Newco or WFI LLC, as
         the case may be.

                                 SCHEDULE 4.3(b)

                         SURVIVING CN SIDE LETTER TERMS

1.       In respect of the contractual relationship between CN and fONOROLA
         Telecommunications, Limited Partnership ("fONOROLA"), which includes a
         telecommunications agreement dated October 1, 1997 ("Telecommunications
         Agreement") and a License Agreement dated April 26, 1995, as amended on
         October 1, 1997 ("fONOROLA License Agreement") (the above-mentioned
         agreements being collectively referred to as the "fONOROLA
         Agreements"), CN has advised WFI as follows:

         (a)  Pursuant to the fONOROLA License Agreement, fONOROLA has a license
              to construct and install fiber optic telecommunications systems
              ("FOTS") along the CN right of way ("CN ROW"), solely for the
              purpose of carrying on the business of owning, upgrading,
              maintaining, installing and marketing Bulk Telecommunications
              Services (Bulk Telecommunications Services being defined as
              unchannelized dedicated and switched transmission capacity). CN
              undertakes not to extend or expand this right of fONOROLA by
              contractual amendment, waiver, renunciation or in any other matter
              whatsoever, without the prior written consent of WFI, over any
              portion of the CN ROW available to WFI or its subsidiary WFI-CN
              pursuant to the Amended and Restated License Agreement made as of
              March 6, 2000 between WFI, WFI-CN and CN ("CN License Agreement").

         (b)  In the event that fONOROLA decides to proceed with the
              construction of a FOTS pursuant to the fONOROLA Agreements, CN
              shall exercise its right as set forth in section 2.4 of the
              Telecommunications Agreement to act as subcontractor for the
              construction of such FOTS and shall engage WFI (or such other
              company as WFI may request), at a fair market rate, subject to the
              payment by WFI to CN of an appropriate referral fee.

         (c)  CN confirms that the only Existing FOTS Party with an ongoing
              right to build on the CN ROW is fONOROLA.

         (d)  In the event that WFI does not agree with CN's view as to
              fONOROLA's right to access the IC ROW under the terms of the
              fONOROLA License Agreement, CN, if so requested by WFI, will
              diligently and in good faith contest any such claim by fONOROLA
              that its license pursuant to the fONOROLA License Agreement
              extends to subsidiaries acquired by CN after April 26, 1995, such
              as IC, provided that all costs and expenses of any court or
              arbitration proceeding taken by or against CN or IC to contest any
              such claim (including reasonable legal fees) related to such
              contestation are paid by WFI and provided that WFI shall indemnify
              CN or IC from any costs or damages which are awarded against CN or
              IC in any such court or arbitration proceedings.

<PAGE>

         (e)  Should fONOROLA's license be found to apply to the right of way of
              Illinois Central Railroad Company ("IC") or part thereof ("IC
              ROW"), then CN shall cause IC to perform the obligations set forth
              in paragraphs 1(a) and (b) of this letter, MUTATIS MUTANDIS.

2.       In connection with the CN License Agreement, CN and WFI each understand
         that WFI-CN may suffer or incur a tax liability as a result of the
         transfer of fibre optic strands to CN and to WFI pursuant to Section
         2.1 of the CN License Agreement. CN agrees to indemnify and save
         harmless WFI-CN from and against any such tax liability suffered or
         incurred by WFI-CN from the disposition of fibre optic strands to CN
         pursuant to Section 2.1 of the CN License Agreement, and all related
         costs, penalties and interest.

3.       CN acknowledges that the licensing transactions between and among CN,
         IC and WFI are intended to include rights of way belonging to railways
         operated by the Grand Trunk Corporation ("GTC"), namely the Grand Trunk
         Western Railroad and the Duluth Winnipeg & Pacific Railroad. Should WFI
         elect to construct any Facility over all or a portion of the rights of
         way belonging to these railways, transaction documents paralleling the
         seven Amended and Restated License Agreements dated as March 6, 2000
         between WFI and IC ("IC License Agreements") on the one hand and each
         of IC Fiber Illinois LLC, IC Fiber Kentucky LLC, IC Fiber Tennessee
         LLC, IC Fiber Mississippi LLC, IC Fiber Louisiana LLC, IC Fiber Alabama
         LLC and IC Fiber Iowa LLC.

4.       CN, GTC and IC hold exclusive rights to grant licenses for the
         installation of fiber optic cable along certain rights of way not owned
         by CN, GTC or IC. The rights of way over which such right to grant
         licenses applies will be identified by CN and, if not previously
         provided by CN to WFI, the details with respect to such rights of way
         will be provided by CN to WFI within thirty days of the execution of
         this Agreement. Subject to the provisions of the agreements between CN,
         GTC and IC and the owners of such rights of way, WFI shall have the
         right to add all or a portion of such rights of way to the Reserved CN,
         IC or GTC ROW List, as the case may be.

5.       Should CN be required by judgement or other order of a court or other
         tribunal (notwithstanding that CN may appeal or otherwise contest such
         judgement or order) other than a judgement or order with respect to the
         existing agreements by and between CN and fONOROLA, or should CN
         reasonably determine that it has a legal obligation, to grant to a
         party other than WFI-CN a license or other rights with respect to the
         CN ROW for the purpose of installing and maintaining a fiber optic
         communications system, CN hereby irrevocably appoints WFI-CN to
         negotiate the consideration for the license or other rights granted to
         such party on a per-mile basis and will pay over to WFI-CN the net
         amount of such consideration when and as received by CN.

3. REPRESENTATIONS AND WARRANTIES OF SELLER AND IC. Seller and IC hereby jointly
and severally represent and warrant to Buyer as of the date hereof and, unless
otherwise provided, as of the Closing Date (as though made then and as though
the Closing Date were substituted for the date hereof throughout this Agreement)
as follows:

         (a)      Neither Seller nor IC has employed any broker or finder in
                  connection with the transactions contemplated by this
                  Agreement. The Buyer acknowledges that Seller and IC have
                  retained Merrill Lynch as an advisor to them, and Seller and
                  IC each represent, warrant and acknowledge to the Buyer that
                  Merrill Lynch is not employed as a broker or finder in
                  connection with the transactions contemplated by this
                  Agreement and that Seller or IC will be responsible for all
                  fees payable to Merrill Lynch.

         (b)      The execution, delivery and performance by Seller and IC of
                  this Agreement and each of the other Unit Transaction
                  Documents and the consummation by Seller and IC of the
                  transactions contemplated hereby and thereby will not (a)
                  violate any provision of law, statute, rule or regulation, or
                  any ruling, writ, injunction, order, judgment or decree of any
                  court, administrative agency or other governmental body
                  applicable to it, or any of its properties or assets; (b)
                  conflict with or result in any breach of any of the terms,
                  conditions or provisions of, or constitute (with due notice or
                  lapse of time, or both) a default (or give rise to any right
                  of termination, cancellation or acceleration) under any
                  contract to which Seller or IC is a party that would
                  materially adversely affect Seller's or IC's ability to
                  consummate the transactions contemplated by this Agreement or
                  perform its obligations under any Unit Transaction Documents;
                  or (c) violate the organizational documents (if any) of Seller
                  or IC.

         (c)      Each of Seller and IC is duly organized and validly existing
                  under the laws of the jurisdiction of its organization and has
                  all corporate power and authority to enter into and carry out
                  the transactions contemplated by each of the Unit Transaction
                  Documents and the performance by Seller and IC of their
                  obligations hereunder and thereunder. Each of the Unit
                  Transaction Documents has been duly authorized by all
                  necessary action on the part of Seller and IC. Each of the
                  Unit Transaction Documents constitutes a valid and binding
                  agreement of Seller and IC, as applicable, enforceable against
                  Seller or IC or both, as the case may be, in accordance with
                  its terms except to the extent that enforceability may be
                  limited by bankruptcy, insolvency or other similar laws
                  affecting creditors' rights generally and by equitable
                  principles generally whether enforced in a court of law or at
                  equity.

         (d)      No permit, authorization, consent or approval of or by, or any
                  notification of or filing with, any government, regulatory

4.       REPRESENTATIONS AND WARRANTIES OF BUYER

                  Buyer hereby represents and warrants to Seller and IC as of

though made then and as though the Closing Date were substituted for the date
hereof throughout this Agreement) as follows:

         (a)      Buyer is a corporation, duly organized, validly existing and
                  in good standing under the laws of the State of Nevada, and
                  has all requisite corporate power and authority to enter into

                  duly authorized by all requisite corporate action on the part
                  of the Buyer. Each Unit Transaction Document constitutes a
                  legal, valid and binding agreement of the Buyer, enforceable
                  against the Buyer in accordance with its terms except to the
                  extent that enforceability may be limited by bankruptcy,
                  insolvency or other similar laws affecting creditors' rights
                  generally and by equitable principles generally, whether
                  enforced in a court of law or at equity.

         (c)      The execution, delivery and performance by the Buyer of the
                  Unit Transaction Documents and the consummation by the Buyer
                  of the transactions contemplated thereby will not (a) violate
                  any provision of law, statute, rule or regulation, or any
                  ruling, writ, injunction, order, judgment or decree of any
                  court, administrative agency or other governmental body
                  applicable to it, or any of its properties or assets; (b)
                  conflict with or result in any breach of any of the terms,
                  conditions or provisions of, or constitute (with due notice or
                  lapse of time, or both) a default (or give rise to any right
                  of termination, cancellation or acceleration) under any
                  contract to which the Buyer is a party that would materially
                  adversely affect the Buyer's ability to consummate the
                  transactions contemplated by any Unit Transaction Document or
                  perform its obligations under any Unit Transaction Document;
                  or (c) violate its organizational documents.

         (d)      No permit, authorization, consent or approval of or by, or any
                  notification of or filing with, any Person is required in
                  connection with the execution, delivery and performance by the
                  Buyer of any Unit Transaction Document, the consummation by
                  the Buyer of the transactions contemplated hereby or thereby
                  (other than such notifications or filings required under
                  applicable securities laws, if any, which shall be made by the
                  Buyer on a timely basis and other than provided for in any
                  Unit Transaction Document).

         (e)      Buyer agrees that by Buyer accepting the Units at Closing,
                  Buyer shall be representing and warranting that the foregoing
                  representations and warranties are

                  if they had been made by Buyer at the Closing Date and shall
                  continue in full force and effect. Buyer undertakes to notify
                  Seller and IC in writing of any change in any representation,
                  warranty or other information relating to Buyer set forth

                  Buyer, Seller or IC containing, or based in whole or in part
                  on, any such information or reflecting any such information,
                  strictly confidential, and shall at no time convey or
                  disclose, or knowingly allow their respective directors,
                  officers, employees, agents, representatives or consultants,
                  if any, to convey or disclose, in any manner whatsoever, to
                  any person, firm or corporation any of the aforesaid
                  information. The parties hereto hereby further covenant and
                  agree with each other not to use, and to take all normal and
                  reasonable steps to ensure that their respective directors,
                  officers, employees, agents, representatives or consultants,
                  if any, do not use, any of the aforesaid information except
                  for the purposes of exercising their respective rights and
                  performing their respective obligations under this Agreement.

         (b)      Each party hereto hereby covenants and agrees with each other
                  party hereto to indemnify and hold harmless each other party
                  hereto from any losses, damages, charges, fees or expenses
                  (including reasonable attorneys' or solicitors' fees) arising
                  out of or resulting from any breach of subsection 6(a). The
                  parties hereto hereby further covenant and agree with each
                  other not to do any act, or knowingly

                  allow their respective directors, officers, employees, agents,
                  representatives or consultants, if any, to do any act, to
                  infringe upon any copyright, patent, industrial design or
                  other proprietary rights of Buyer or its affiliates.

         (c)      The parties hereto hereby further covenant and agree with each
                  other that, in the event they, or their respective directors,
                  officers, employees, agents, representatives or consultants,
                  if any, become legally compelled to disclose any of the
                  aforesaid information, or are advised by their respective
                  legal counsel that such disclosure is required to comply with
                  applicable law, to immediately provide the other parties with
                  written notice so that the other parties may seek a protective
                  order or other appropriate remedy, and to cooperate, and to
                  cause their respective directors, officers, employees, agents,
                  representatives and consultants, if any, to cooperate, with
                  the other parties in any effort undertaken to obtain a
                  protective order or other remedy. Each party hereto hereby
                  further covenants and agrees with each other party to, in the
                  event that such protective order or remedy is not obtained,
                  furnish, and to cause his directors, officers, employees,
                  agents, representatives and consultants, if any, to furnish,
                  only that portion of the aforesaid information which he is
                  legally required to furnish, and to use his best efforts, and
                  to cause his directors, officers, employees, agents,
                  representatives, and consultants, if any, to use their best
                  efforts, to obtain an assurance from the recipient of any of
                  the aforesaid information that confidential treatment will be
                  accorded to such information, to the extent that such
                  assurance is available. Notwithstanding the foregoing, each of
                  the parties acknowledges that the parties may be required to
                  disclose the terms of this Agreement, and provide a copy of
                  this Agreement, in filings made by such party under applicable
                  securities law, and may have to disclose the aforesaid
                  information in an open court in legal proceedings between the
                  parties, or between a party and others, and each of the
                  parties hereby consents to such disclosure and to the filing
                  of a copy of this Agreement for public viewing under filings
                  required to be made by a party under applicable securities
                  law.

         (d)      Each party hereto hereby acknowledges to and covenants and
                  agrees with each other party hereto that a breach by him of
                  any of his covenants contained in this Section 6 may result in
                  damages to each of the other parties and that a monetary award
                  would not adequately compensate for such damages, and,
                  accordingly, that in the event of any such breach, in addition
                  to all other remedies available in law or in equity, the other
                  parties, or any of them, shall be entitled as a matter of
                  right to apply to a court of competent equitable jurisdiction
                  for such relief by way of restraining order, injunction,
                  decree or otherwise as may be appropriate to ensure compliance
                  by him with Section 6.

         (e)      Each of the parties hereto hereby acknowledges to and
                  covenants and agrees with each of the other parties hereto
                  that, notwithstanding any provision of this Agreement, its
                  covenants contained in Section 6 survive any termination of
                  this Agreement.

                  affected by any investigation of the subject matter thereof
                  made by or on behalf of Buyer, Seller or IC. All statements
                  contained in any certificate or other instrument delivered by

                  protect and enforce its rights either by suit in equity and/or
                  by action at law, including, but not limited to, an action for
                  damages as a result of any such breach and/or an action for
                  specific performance of any such covenant or agreement
                  contained in this Agreement, and to exercise all other rights
                  existing in their favor. The parties hereto agree and
                  acknowledge that money damages may not be an adequate remedy
                  for any breach of the provisions of this Agreement and that
                  each party may in its sole discretion apply to any court of
                  law or equity of competent jurisdiction for specific
                  performance and/or injunctive relief (without posting a bond
                  or other security) in order to enforce or prevent any

                  instruments or documents and to take all such further action
                  as the other party may reasonably request in order to evidence
                  or effectuate the consummation of the transactions
                  contemplated hereby and to otherwise carry out the intent of
                  the parties hereunder.
